[0065] The mobile communication system provided in this application embodiment can be applied to at least one of the following communication scenarios: uplink communication scenario, downlink communication scenario, and sidelink communication scenario.

[0066] The following section describes the relevant technologies involved in the embodiments of this application:

[0067] • Physical downlink control channel detection:

[0068] Network devices send DCIs to terminal devices. DCIs are used for downlink scheduling, such as scheduling the Physical Downlink Shared Channel (PDSCH), or for uplink granting, such as scheduling the Physical Uplink Shared Channel (PUSCH), or for transmitting common control information. DCIs are carried via PDCCHs. Network devices configure a search space for terminal devices. Different aggregation levels (ALs) can be configured, and at each aggregation level, the number of candidate PDCCHs the terminal device needs to monitor is configured. Terminal devices need to perform PDCCH detection in the search space. The maximum number of PDCCHs the terminal device needs to monitor in a time slot is related to the subcarrier spacing. For example, with a 15kHz subcarrier spacing, the maximum number of PDCCHs the terminal device needs to monitor in a time slot is 44. Referring to Table 1, subcarrier spacing parameter μ values ​​of 0, 1, 2, and 3 correspond to subcarrier spacings of 15kHz, 30kHz, 60kHz, and 120kHz, respectively.

[0069] Table 1

[0070] In 5G NR systems, DCI uses Polar encoding. Each time the terminal detects PDCCH, it needs to perform decoding, which leads to higher power consumption and increased processing latency.

[0071] A PDCCH's transmission resources can include M1 Control Channel Elements (CCEs), corresponding to different aggregation levels (ALs). For example, M1 = 1, 2, 4, 8, 16. The relationship between aggregation level and the number of CCEs is shown in Table 2 below. Each CCE can include M2 ​​Resource Element Groups (REGs). For example, M2 = 6. One REG corresponds to a Physical Resource Block (PRB) in the frequency domain and an Orthogonal Frequency Division Multiplexing (OFDM) symbol in the time domain. The transmission reliability varies depending on the number of CCEs occupied by the PDCCH. For example, the more CCEs a PDCCH occupies, the higher its transmission reliability.

[0072] Table 2

[0073] • Optimization of terminal device complexity:

[0074] Terminal devices, often simply referred to as terminals, are designed to support extremely high peak data rates. Therefore, the requirements for terminal capabilities are quite high. The LTE standard defines a maximum single-carrier bandwidth of 20MHz, with larger bandwidths achieved through multi-carrier aggregation. 5G NR ultimately defines a maximum carrier bandwidth of 100MHz for frequencies below 6GHz, five times that of LTE, while the maximum carrier bandwidth for millimeter-wave frequencies is 400MHz. The required multiple-input multiple-output (MIMO) antenna configuration for NR has also been further increased. The reference antenna configuration for LTE terminals is one transmit and two receive antennas, while NR R15 requires two transmit and four receive antennas at frequencies above 2500MHz.

[0075] However, some NR applications do not require such high processing power in terms of capacity and speed. These applications include the Internet of Things (IoT), industrial automation, and wearable devices. These scenarios demand communication hardware with low size and power consumption; lightweight capability is a characteristic of these terminals. Based on this consideration, NR Release 17 research introduced a compact terminal standard with reduced capability (RedCap).

[0076] The Compact Terminal standard reduces some mandatory capabilities of NR R15 / R16. Corresponding terminal function groups are defined for these capabilities. The Compact Terminal standard also further optimizes terminal identification, access procedures, and power consumption in measurements to suit relevant application scenarios. This compact terminal design significantly reduces the complexity of terminal hardware and correspondingly reduces power consumption, thus achieving energy savings.

[0077] Before introducing the technical solution of this application, some contents involved in this application will be described first. The following contents are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and all of them fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0078] In some embodiments, the set of transmission resources configured by the network device for the terminal device includes at least two types of transmission resources.

[0079] Optionally, a set of transmission resources includes a first transmission resource and other transmission resources, where the other transmission resources are those other than the first transmission resource. For example, the other transmission resources include a second transmission resource. The first transmission resource is used to transmit first indication information, and the second transmission resource is used for downlink transmission. The transmission content of the downlink transmission (i.e., the downlink transmission content) includes downlink data and / or downlink control information (DCI). The following embodiments primarily illustrate this by citing the inclusion of a second transmission resource among the other transmission resources, but are not limited thereto. For example, the other transmission resources may also include a third transmission resource for uplink transmission.

[0080] In this embodiment, the network device configures a first transmission resource and a second transmission resource to the terminal device, and there is an association between the first transmission resource and the second transmission resource. The terminal device can determine the location of the second transmission resource based on the location of the first transmission resource.

[0081] The correspondence between the first transmission resource and the second transmission resource

[0082] In some embodiments, the correspondence may also be referred to as the association.

[0083] In some embodiments, the correspondence between the first transmission resource and the second transmission resource is one-to-one, many-to-one, one-to-many, or many-to-many; wherein, one-to-one means that one first transmission resource corresponds to one second transmission resource, many-to-one means that multiple first transmission resources correspond to the same second transmission resource, one-to-many means that one first transmission resource corresponds to multiple second transmission resources, and many-to-many means that multiple first transmission resources correspond to multiple second transmission resources.

[0084] Optionally, when the correspondence between the first transmission resources and the second transmission resources is many-to-one, at least one of the time-domain resources, frequency-domain resources, or code-domain resources corresponding to the multiple first transmission resources is different. For example, the multiple first transmission resources have the same time-domain resources but different frequency-domain resources; or, the multiple first transmission resources have different time-domain resources but the same frequency-domain resources; or, the multiple first transmission resources have the same time-domain resources and the same frequency-domain resources, but different code-domain resources. For example, the multiple first transmission resources are located in the same time-domain symbol, but the corresponding PRBs are different; or, for another example, the multiple first transmission resources are located in different time-domain symbols, but the same frequency-domain resources; or, for yet another example, the multiple first transmission resources are located in the same time-domain symbol, the same frequency-domain resources, but correspond to different sequences.

[0085] Optionally, when the correspondence between the first and second transmission resources is one-to-many, the multiple second transmission resources have the same time-domain resources but different frequency-domain resources; or, the multiple second transmission resources have different time-domain resources but the same frequency-domain resources. For example, the multiple second transmission resources are located in the same time-domain symbol, but their corresponding PRBs are different; or, for another example, the multiple second transmission resources have different time-domain resources but the same frequency-domain resources.

[0086] Optionally, when the correspondence between the first transmission resource and the second transmission resource is many-to-many, if the multiple first transmission resources include A first transmission resources and the multiple second transmission resources include B second transmission resources, then A1 first transmission resources correspond to B1 second transmission resources, where A, A1, B, and B1 are integers, 1≤A1≤A, and 1≤B1≤B.

[0087] Figure 2 illustrates a schematic diagram of the correspondence between transmission resources provided in an exemplary embodiment of this application.

[0088] In Figure 2(a), the first transmission resource and the second transmission resource have a one-to-one correspondence, that is, one first transmission resource corresponds to one second transmission resource; in Figure 2(b), the first transmission resource and the second transmission resource have a many-to-one correspondence, that is, two first transmission resources correspond to the same second transmission resource; in Figure 2(c), the first transmission resource and the second transmission resource have a one-to-many correspondence, that is, one first transmission resource corresponds to two second transmission resources; in Figure 2(d), the first transmission resource and the second transmission resource have a many-to-many correspondence, that is, any one of the two first transmission resources corresponds to both of the two second transmission resources, or, any one of the two first transmission resources corresponds to either of the two second transmission resources.

[0089] Positional relationship between the first transmission resource and the second transmission resource

[0090] In some embodiments, the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the location of the second transmission resource and the location of the first transmission resource based on a communication protocol; or, there is a pre-configured relationship between the location of the second transmission resource and the location of the first transmission resource based on a network.

[0091] By way of example and not limitation, the positional relationship between the first transmission resource and the second transmission resource includes at least one of the following:

[0092] The first transmission resource and the second transmission resource are not adjacent in the time domain; the first transmission resource and the second transmission resource are adjacent in the time domain; the start position of the time domain of the first transmission resource is the same as the start position of the time domain of the second transmission resource; the start position of the frequency domain of the first transmission resource is the same as the start position of the frequency domain of the second transmission resource; the center position of the frequency domain of the first transmission resource is the same as the center position of the frequency domain of the second transmission resource; the end position of the frequency domain of the first transmission resource is the same as the end position of the frequency domain of the second transmission resource.

[0093] The temporal adjacency between the first transmission resource and the second transmission resource means that the temporal end position of the first transmission resource is adjacent to the temporal start position of the second transmission resource.

[0094] Figure 3 illustrates a schematic diagram of the positional relationship between transmission resources provided in an exemplary embodiment of this application.

[0095] In part (a) of Figure 3, the first transmission resource and the second transmission resource are not adjacent in the time domain, and the frequency domain center position of the first transmission resource is the same as that of the second transmission resource.

[0096] In part (b) of Figure 3, the first transmission resource and the second transmission resource are temporally adjacent, and the frequency domain center position of the first transmission resource is the same as that of the second transmission resource.

[0097] In part (c) of Figure 3, the starting position of the time domain of the first transmission resource is the same as the starting position of the time domain of the second transmission resource, and the starting position of the frequency domain of the first transmission resource is the same as the starting position of the frequency domain of the second transmission resource.

[0098] In part (d) of Figure 3, the starting position of the time domain of the first transmission resource is the same as the starting position of the time domain of the second transmission resource, and the center position of the frequency domain of the first transmission resource is the same as the center position of the frequency domain of the second transmission resource.

[0099] In part (e) of Figure 3, the time domain start position of the first transmission resource is the same as the time domain start position of the second transmission resource, and the frequency domain end position of the first transmission resource is the same as the frequency domain end position of the second transmission resource.

[0100] Types of first and second transmission resources

[0101] In some embodiments, the first transmission resource and the second transmission resource are common transmission resources shared by multiple terminal devices; or, the first transmission resource and the second transmission resource are group transmission resources shared by a group of terminal devices; or, the first transmission resource and the second transmission resource are proprietary transmission resources used by a single terminal device.

[0102] In some embodiments, when the first transmission resource and the second transmission resource are common transmission resources shared by multiple terminal devices or group transmission resources shared by a group of terminal devices, the second transmission resource is used to transmit common DCI and / or common downlink data. The common DCI and / or common downlink data is used to transmit at least one of the following information: broadcast information, system information, paging information, and random access response information.

[0103] In some embodiments, the network device configures the same first transmission resource and the same second transmission resource for multiple terminal devices, that is, the first transmission resource and the second transmission resource are shared by multiple terminal devices; the network device configures the same sequence for multiple terminal devices, or the network device configures their respective corresponding sequences for multiple terminal devices, and the terminal devices detect the first indication information on the first transmission resource based on the configured sequence.

[0104] For example, the network device configures Sequence 1 for terminal device 1 and Sequence 1 for terminal device 2. Both terminal device 1 and terminal device 2 detect first indication information on the first transmission resource based on Sequence 1.

[0105] For example, the network device configures sequence 1 for terminal device 1 and sequence 2 for terminal device 2. Terminal device 1 detects first indication information on the first transmission resource based on sequence 1, and terminal device 2 detects first indication information on the first transmission resource based on sequence 2.

[0106] The network device is configured with a first transmission resource and a second transmission resource for transmitting common DCI and / or common downlink data. A first indication information is transmitted on the first transmission resource, and the sequence corresponding to the first indication information is a common sequence. Common DCI and / or common downlink data are transmitted on the second transmission resource.

[0107] In some embodiments, multiple terminal devices detect whether there is first indication information on the first transmission resource based on the same common sequence.

[0108] For example, the network device configures a common sequence 1 for terminal device 1 and terminal device 2, and terminal device 1 and terminal device 2 detect first indication information on the first transmission resource based on the common sequence 1.

[0109] If the terminal device detects the first indication information, it detects common DCI and / or common downlink data on the second transmission resource based on the first indication information. The common DCI and common downlink data are used to transmit at least one of the following information: broadcast information, system information, paging information, and random access response information.

[0110] This includes broadcast information such as Master Information Block (MIB) information; system information such as System Information Block (SIB) information; paging information such as paging information; and random access response information such as Random Access Response (RAR) information.

[0111] In some embodiments, the network device is configured with common transport resources, including common first transport resources and common second transport resources, for transmitting common DCI and common downlink data.

[0112] The common first transmission resource and the common second transmission resource can also be referred to as cell-specific first transmission resource and cell-specific second transmission resource, or common first transmission resource and common second transmission resource.

[0113] Optionally, network devices can be configured with different types of group transmission resources. It should be noted that the "group" in group transmission resources here refers to a terminal group, not the group in the group transmission resources mentioned above.

[0114] In some embodiments, in a first configuration, the network device configures a group transmission resource shared by a group of terminal devices, including a first group transmission resource and a second group transmission resource. The second group transmission resource is used to transmit group common DCI or group common downlink data. Optionally, the terminal device group includes all terminal devices within the cell, and the first group transmission resource and the second group transmission resource can also be referred to as shared first transmission resource and shared second transmission resource. For example, the common DCI and common downlink data are used to transmit at least one of the following: slot format information, channel occupation time duration information, available resource block set information, search space set group switching information, pre-emption indication information, transmission power control (TPC), uplink transmission cancellation indication information, and wake-up indication information.

[0115] In some embodiments, in the second configuration, the network device configures a group transmission resource shared by a group of terminal devices, including a group second transmission resource. The network device configures different first transmission resources for the group of terminal devices. For example, the network device configures the same second transmission resource for the group of terminal devices, but configures different first transmission resources. For each terminal device, there is an association between its configured first transmission resource and second transmission resource; this configuration method can enable multiple terminal devices to reuse or share the second transmission resource.

[0116] For example, Figure 4 shows a schematic diagram of the configuration transmission resources provided in an exemplary embodiment of this application.

[0117] Part (a) in Figure 4 corresponds to the first configuration method described above, where the network device configures the same first transmission resource and the same second transmission resource for UE1 and UE2, and UE1 and UE2 share the first and second transmission resources. In some embodiments, the network device only sends the first indication information to UE1 to indicate the transmission content on the second transmission resource. UE1 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource. In some embodiments, the network device only sends the first indication information to UE2 to indicate the transmission content on the second transmission resource. UE2 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource.

[0118] Part (b) in Figure 4 corresponds to the second configuration described above, where the network device configures the same second transmission resource for UE1 and UE2, and different first transmission resources for UE1 and UE2, with UE1 and UE2 sharing the second transmission resource. In some embodiments, the network device only sends the first indication information for UE1 to indicate that UE1's transmission content is being transmitted on the second transmission resource, without sending the first indication information for UE2, or sends the first indication information for UE2 to indicate that there is no transmission on the second transmission resource. UE1 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource. UE2 determines that detection is not needed on the second transmission resource based on the first indication information detected on the first transmission resource. In some embodiments, the network device only sends the first indication information for UE2 to indicate that UE2's transmission content is being transmitted on the second transmission resource, without sending the first indication information for UE1, or sends the first indication information for UE1 to indicate that there is no transmission on the second transmission resource. UE2 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource. UE1 determines that detection is not needed on the second transmission resource based on the first indication information detected on the first transmission resource.

[0119] Part (c) of Figure 4 corresponds to the second configuration method described above. Part (c) of Figure 4 has the same configuration method as part (b) of Figure 4, that is, the network device configures the same second transmission resource for UE1 and UE2, and configures different first transmission resources for UE1 and UE2. UE1 and UE2 share the second transmission resource. In part (c) of Figure 4, the first indication information sent by the network device to either UE1 or UE2 indicates the value of the transmission parameters corresponding to the content transmitted on the second transmission resource. For example, the first indication information sent on the first transmission resource of UE1 indicates that the transmission resource of UE1's DCI occupies only half of the second transmission resource; the first indication information sent on the first transmission resource of UE2 also indicates that the transmission resource of UE2's DCI occupies only half of the second transmission resource, and UE1 and UE2 occupy different resources on the second transmission resource, thus allowing the two UEs to simultaneously reuse the second transmission resource for transmission.

[0120] In some embodiments, the network device configures a user-specific first transmission resource and a user-specific second transmission resource for each terminal device. The user-specific first transmission resource is used to transmit a first indication information specific to each terminal device, and the user-specific second transmission resource is used to transmit a user-specific DCI or user-specific downlink data for each terminal device.

[0121] In some embodiments, the proprietary first transmission resources of different terminal devices do not overlap, completely overlap, or partially overlap, and the proprietary second transmission resources of different terminal devices do not overlap, completely overlap, or partially overlap.

[0122] For example, Figure 5 illustrates a schematic diagram of the configuration of transmission resources provided in an exemplary embodiment of this application. The network device is configured with common transmission resources, group transmission resources, and dedicated transmission resources. The common transmission resources include two groups of common first transmission resources and two groups of common second transmission resources; the group transmission resources include two groups of group first transmission resources and two groups of group second transmission resources; and the dedicated transmission resources include eight groups of dedicated first transmission resources and dedicated second transmission resources. For the dedicated transmission resources, the network device can configure one or more dedicated first transmission resources and dedicated second transmission resources for each terminal device. Assuming the network device configures one group of common first transmission resources and one group of common second transmission resources, one group of group first transmission resources and one group of group second transmission resources, and two groups of dedicated first transmission resources and dedicated second transmission resources for a terminal device, the terminal device needs to perform detection in these four groups of transmission resources (e.g., detecting the presence of first indication information in the first transmission resources), and then detect DCI and / or downlink data in the corresponding second transmission resources. By dividing a set of transmission resources into different types of transmission resources, and with network devices configured with at least one of public transmission resources, group transmission resources, and dedicated transmission resources, the scope of terminal device detection is narrowed, and detection efficiency is improved.

[0123] The method of instruction for the first instruction information

[0124] Figure 6 illustrates a schematic diagram of the indication method of the first indication information provided in an exemplary embodiment of this application. The first indication information is used to indicate at least one of the following:

[0125] Method 1: Indicates that the second transmission resource is not transmitting.

[0126] If the first indication information indicates that there is no transmission on the second transmission resource, the terminal device does not need to perform detection on the second transmission resource;

[0127] Optionally, a first value, a first state, or a first sequence is determined based on the first indication information, and it is determined not to transmit on the second transmission resource based on the first value, the first state, or the first sequence.

[0128] Here, the first value is a single bit value or a group of bit values, such as 1 or 0; the first state is an on or off state, which can be represented by a high or low voltage level or a high or low energy level, or by a bit value; the first sequence is a sequence used to represent the first indication information, such as the ZC sequence. The representation principles of other values, states, and sequences, such as the second value, second state, second sequence, third value, third state, and third sequence, are the same and will not be repeated.

[0129] In some implementations, if the terminal does not detect the first indication information on the first transmission resource, it can be determined that there is no transmission on the second transmission resource. That is, the absence of the first indication information on the first transmission resource is used to determine that there is no transmission on the second transmission resource.

[0130] Method 2: Instruct the transmission of DCI or PDCCH on the second transmission resource.

[0131] In some embodiments, DCI or PDCCH is received on a second transport resource based on first indication information.

[0132] When the first indication information indicates that DCI or PDCCH is transmitted on the second transmission resource, the terminal device detects DCI or PDCCH on the second transmission resource. For example, a search space is configured on the second transmission resource, and the terminal device detects DCI or PDCCH in the search space. In some embodiments, the detection complexity of the search space is low, such as configuring only one aggregation level in the search space, and configuring 2 candidate PDCCHs under the aggregation level, that is, the terminal device only needs to perform a maximum of 2 PDCCH detections in the search space.

[0133] Optionally, a second value, a second state, or a second sequence is determined based on the first indication information, and DCI or PDCCH is transmitted on the second transmission resource based on the second value, the second state, or the second sequence.

[0134] Method 3: Instruct the second transmission resource to transmit the first downlink data.

[0135] In some embodiments, the terminal device receives first downlink data on the second transmission resource based on first indication information. Optionally, if there is no indication that first downlink data is being transmitted on the second transmission resource, it is not necessary to detect the first downlink data on the second transmission resource.

[0136] When the first indication information indicates that the first downlink data is to be transmitted on the second transmission resource, the terminal device detects the first downlink data on the second transmission resource. Optionally, the first downlink data is carried via PDSCH;

[0137] Optionally, a third value, a third state, or a third sequence is determined based on the first indication information, and the first downlink data is transmitted on the second transmission resource based on the third value, the third state, or the third sequence.

[0138] Method 4: Instruct the transmission of DCI and first downlink data on the second transmission resource.

[0139] In some embodiments, based on the first indication information, DCI and first downlink data are simultaneously received on the second transmission resource, or, based on the first indication information, downlink control channel and first downlink data are simultaneously received on the second transmission resource.

[0140] As an example and not a limitation, DCI is used to schedule second downlink data; or, DCI is used to schedule second uplink data.

[0141] Wherein, the DCI used for scheduling the second downlink data includes: the DCI used to indicate the transmission resources of the second downlink data, and / or, the DCI used to indicate the transmission parameters of the second downlink data; the DCI used for scheduling the second uplink data includes: the DCI used to indicate the transmission resources of the second uplink data, and / or, the DCI used to indicate the transmission parameters of the second uplink data.

[0142] Features of the first instruction information

[0143] In some embodiments, the first indication information is indicated by a sequence, or it can be understood that the first indication information is carried by a sequence. The sequence type used to carry the first indication information includes at least one of complex (vector) sequences and real sequences. The complex (vector) sequences include at least one of the following: Constant Amplitude Zero Auto-Corelation (CAZAC) sequences; ZC (Zaddoff Chu) sequences. The real sequences include at least one of the following: pseudo-random sequences; Gold sequences; m-sequences; Hadamard sequences. Alternatively, the sequence used to carry the first indication information is generated or determined based on the above sequence types.

[0144] Sending the first indication information in a sequential manner allows the terminal device to determine the information indicated by the first indication information based on sequence detection (such as sequence correlation detection), avoiding decoding processing and reducing the power consumption and processing latency of the terminal device.

[0145] In some embodiments, the first indication information is carried by a first sequence, the length of which is determined by at least one of the following methods: based on protocol predefined information; based on configuration information sent by the network; or based on the size of the frequency domain resources included in the first transmission resources.

[0146] For example, the first transmission resource includes K subcarriers or resource elements (REs), the sequence length L is the largest prime number less than or equal to K, or is the largest prime number less than or equal to (K / A), and A is a preset positive integer, such as A = 2 or 4.

[0147] For example, the sequence length L is the largest prime number less than or equal to K, K = 60, L = 59; or K = 72, L = 71; or K = 120, L = 113.

[0148] In some embodiments, the first indication information is carried by a first bit or at least one bit, which is processed by channel coding, modulation, etc., to generate a data packet or transport block.

[0149] The first indication information is carried by a sequence or at least one bit.

[0150] In some embodiments, the first indication information is carried by a sequence or at least one bit; this application primarily describes the first indication information carried by a sequence. Optionally, the sequence index of the sequence is associated with the transmitted content. Here, at least one bit may also be referred to as at least one information bit, or a bit sequence. Optionally, the correspondence between the sequence index and the transmitted content is determined through protocol predefined information or network configuration information.

[0151] For example, the first indication information is carried by four sequences, and the correspondence between the sequence index and the transmitted content is shown in Table 3.

[0152] Table 3

[0153] For example, when the sequence index is 0, the corresponding transmission content is "no transmission on the second transmission resource"; when the sequence index is 1, the corresponding transmission content is "transmission of the second DCI on the second transmission resource"; when the sequence index is 2, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource"; and when the sequence index is 3, the corresponding transmission content is "transmission of the first downlink data and the second DCI on the second transmission resource". The sequence index is represented in decimal, but in actual implementation, it can be represented in binary. This embodiment does not limit this.

[0154] It should be noted that Table 3 above is merely an exemplary illustration of the correspondence between sequence indices and transmitted content, and the method implemented in this application is not limited to the correspondence in Table 3. In some embodiments, the correspondence of network configuration only includes a portion of the content in the table above, such as only including any two rows in the table above; in some embodiments, the correspondence of network configuration includes K sequence indices, and the corresponding transmitted content is also K, where K is an integer greater than or equal to 1.

[0155] The first indication information is used to indicate the first value.

[0156] In some embodiments, the first indication information is used to indicate a first value, which is associated with the transmitted content.

[0157] Optionally, the correspondence between the first value and the transmitted content is determined through protocol predefined information or network configuration information.

[0158] For example, the first indication information is used to indicate four values ​​of the first value, and the correspondence between the first value and the transmitted content is shown in Table 4:

[0159] Table 4

[0160] For example, when the first value is 0, the corresponding transmission content is "no transmission on the second transmission resource"; when the first value is 1, the corresponding transmission content is "transmission of the second DCI on the second transmission resource"; when the first value is 2, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource"; and when the first value is 3, the corresponding transmission content is "transmission of the first downlink data and the second DCI on the second transmission resource". The first value is represented in decimal, but in actual implementation, it can be represented in binary. This embodiment does not limit this.

[0161] It should be noted that Table 4 above is merely an exemplary illustration of the correspondence between the first value and the transmitted content, and the method implemented in this application is not limited to the correspondence in Table 4. In some embodiments, the correspondence of network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the correspondence of network configuration includes K first values, and the corresponding transmitted content is also K, where K is an integer greater than or equal to 1.

[0162] The transmission content on the second transmission resource is determined based on the first indication information and / or the first information associated with the first indication information.

[0163] In some embodiments, the transmission content on the second transmission resource is determined based on the first indication information; or, the transmission content on the second transmission resource is determined based on the first information associated with the first indication information; or, the transmission content on the second transmission resource is determined based on the information combination of the first indication information and the first information associated with the first indication information.

[0164] In some embodiments, the first indication information is carried by a first sequence or at least one bit. Determining the transmission content on the second transmission resource based on the first indication information can also be understood as determining the transmission content on the second transmission resource based on the sequence or at least one bit carrying the first indication information. Optionally, different sequences or different bits indicate different transmission content on the second transmission resource.

[0165] In some embodiments, the first information includes at least one of the following: frequency domain resources corresponding to the first indication information, time domain resources corresponding to the first indication information, and first parameters corresponding to the first sequence carrying the first indication information. Optionally, the first parameters include at least one of the following: an initial value corresponding to the first sequence, a cyclic shift value corresponding to the first sequence, a group number corresponding to the first sequence, a root sequence number within the group corresponding to the first sequence, a sequence length corresponding to the first sequence, and a sequence index corresponding to the first sequence. The first sequence is used to carry the first indication information.

[0166] For example, different lengths of the first sequence correspond to different values, different states, different sequences, or different indices, thereby indicating different transmission content on the second transmission resource.

[0167] For example, the different frequency domain resources corresponding to the first indication information correspond to different values, different states, different sequences, or different indices, thereby indicating different transmission content on the second transmission resource, wherein the sequence is used to carry the first indication information.

[0168] For example, the different time-domain resources corresponding to the first indication information correspond to different values, different states, different sequences, or different indices, thereby indicating different transmission content on the second transmission resource, wherein the sequence is used to carry the first indication information.

[0169] For example, different sequence groups corresponding to the first sequence correspond to different values, different states, different sequences, or different indices, thereby indicating different transmission content on the second transmission resource.

[0170] In some embodiments, the transmission content on the second transmission resource is determined based on different first information associated with the first indication information. This can be understood as indicating the transmission content on the second transmission resource based on different first information associated with the first indication information.

[0171] In some embodiments, the transmission content on the second transmission resource is determined based on different values ​​of the first information associated with the first indication information. This can be understood as indicating the transmission content on the second transmission resource based on different values ​​of the first information associated with the first indication information.

[0172] Taking the use of first indication information to indicate the transmission content on the second transmission resource as an example, the first indication information is carried by a first sequence or at least one bit, and different values ​​of different first sequences or at least one bit can be used to indicate the transmission content on the second transmission resource.

[0173] Taking the use of first information to indicate the transmission content on the second transmission resource as an example, at least five different indication methods can be used to indicate the transmission content on the second transmission resource, wherein the first sequence is used to carry the first indication information.

[0174] Indication Method A: Indicates the transmission content on the second transmission resource based on the length corresponding to the first sequence;

[0175] Instruction Method B: Indicates the transmission content on the second transmission resource based on the frequency domain resource corresponding to the first instruction information;

[0176] Instruction Method C: Indicates the transmission content on the second transmission resource based on the time domain resource corresponding to the first instruction information;

[0177] Indication method D: Indicates the transmission content on the second transmission resource based on the sequence index corresponding to the first sequence;

[0178] Indication method E: Indicates the transmission content on the second transmission resource based on the sequence group index corresponding to the first sequence.

[0179] In some embodiments, the content transmitted on the second transmission resource includes at least one of the following:

[0180] No transmission on the second transmission resource; DCI or PDCCH is transmitted on the second transmission resource; first downlink data is transmitted on the second transmission resource; DCI and first downlink data are transmitted on the second transmission resource.

[0181] For indication method A: The transmission content on the second transmission resource is indicated based on the length corresponding to the first sequence;

[0182] There is a correlation or correspondence between sequence length and transmitted content, which is determined based on protocol predefined information or network configuration information.

[0183] For example, the length corresponding to the first sequence indicates a transmission content on the second transmission resource, the length index value 1 indicates that there is no transmission on the second transmission resource, the length index value 2 indicates that DCI or PDCCH is transmitted on the second transmission resource, the length index value 3 indicates that the first downlink data is transmitted on the second transmission resource, etc. This application does not limit this.

[0184] For indication method B: The transmission content on the second transmission resource is indicated based on the frequency domain resource corresponding to the first indication information;

[0185] There is an association or correspondence between the frequency domain resources and the transmission content corresponding to the first indication information, and this association or correspondence is determined based on protocol predefined information or network configuration information.

[0186] The frequency domain resources corresponding to the first indication information can be understood as the frequency domain resources corresponding to the first transmission resources where the first indication information is located; or, they can be understood as the frequency domain resources corresponding to the first indication information in the first transmission resources; or, they can be understood as the frequency domain resources that carry the first indication information in the first transmission resources.

[0187] For example, based on the frequency domain resource corresponding to the first indication information, a transmission content is indicated on the second transmission resource; frequency domain resource index value 1 indicates that there is no transmission on the second transmission resource; frequency domain resource index value 2 indicates that DCI or PDCCH is transmitted on the second transmission resource; frequency domain resource index value 3 indicates that the first downlink data is transmitted on the second transmission resource, etc. This application does not limit this.

[0188] For indication method C: The transmission content on the second transmission resource is indicated based on the time domain resource corresponding to the first indication information;

[0189] There is an association or correspondence between the time-domain resources and the transmitted content corresponding to the first indication information, and this association or correspondence is determined based on protocol predefined information or network configuration information.

[0190] The time-domain resource corresponding to the first indication information can be understood as the time-domain resource corresponding to the first transmission resource where the first indication information is located; or, it can be understood as the time-domain resource corresponding to the first indication information in the first transmission resource; or, it can be understood as the time-domain resource carrying the first indication information in the first transmission resource.

[0191] For example, based on the time domain resource corresponding to the first indication information, a transmission content is indicated on the second transmission resource; time domain resource index value 1 indicates that there is no transmission on the second transmission resource; time domain resource index value 2 indicates that DCI or PDCCH is transmitted on the second transmission resource; time domain resource index value 3 indicates that the first downlink data is transmitted on the second transmission resource, etc. This application does not limit this.

[0192] For indication method D: The transmission content on the second transmission resource is indicated based on the sequence index corresponding to the first sequence;

[0193] There is an association or correspondence between the sequence index corresponding to the sequence and the transmitted content. This association or correspondence is determined based on protocol predefined information or network configuration information.

[0194] For example, the sequence index corresponding to the first sequence indicates a transmission content on the second transmission resource, sequence index 1 indicates no transmission on the second transmission resource, sequence index 2 indicates DCI or PDCCH transmission on the second transmission resource, sequence index 3 indicates first downlink data transmission on the second transmission resource, etc. This application does not limit this.

[0195] For indication method E: The transmission content on the second transmission resource is indicated based on the sequence group index corresponding to the first sequence.

[0196] There is an association or correspondence between the sequence group index corresponding to the sequence and the transmitted content. This association or correspondence is determined based on protocol predefined information or network configuration information.

[0197] For example, the sequence group index corresponding to the first sequence indicates a transmission content on the second transmission resource, sequence group index 1 indicates no transmission on the second transmission resource, sequence group index 2 indicates DCI or PDCCH transmission on the second transmission resource, sequence group index 3 indicates first downlink data transmission on the second transmission resource, etc. This application does not limit this.

[0198] The first indication information is carried in a sequence, which allows the terminal device to determine the content indicated by the first indication information based on sequence detection. Based on sequence detection, the transmission behavior on the subsequent second transmission resource can be determined, and decoding processing is avoided, reducing the power consumption and processing latency of the terminal device.

[0199] Second transmission resources

[0200] In some embodiments, the second transmission resource is used to transmit DCI or downlink data, and the terminal device determines whether to perform detection on the second transmission resource based on the first indication information, or determines to detect DCI or downlink data on the second transmission resource based on the first indication information.

[0201] 1) The second transmission resource is used to transmit DCI.

[0202] First indication information is transmitted on a first transmission resource, and the first indication information indicates that DCI is transmitted on a second transmission resource. Optionally, DCI is used to schedule the transmission of uplink data (e.g., PUSCH), or to schedule the transmission of downlink data (e.g., PDSCH), or for other purposes, which are not limited in this application embodiment.

[0203] Figure 7 shows a schematic diagram of DCI scheduling data provided in an exemplary embodiment of this application.

[0204] In Figure 7(a), when the DCI is used to schedule downlink data, the DCI indicates that downlink data should be transmitted on the third transmission resource. The DCI can also indicate parameters for downlink data transmission, which the terminal device uses to perform downlink data reception based on the indicated parameters.

[0205] In Figure 7(b), when the DCI is used to schedule uplink data, the DCI indicates that uplink data should be transmitted on the fourth transport resource. The DCI can also indicate parameters for uplink data transmission, which the terminal device uses to perform uplink data transmission based on the indicated parameters.

[0206] In some embodiments, DCI is carried on PDCCH, and the network device configures the search space in the second transport resource by sending network configuration information, and the terminal device detects PDCCH in the search space. Optionally, DCI is carried on PDCCH or PDSCH.

[0207] In some embodiments, at least one of the following information is determined based on protocol predefined information or network configuration information:

[0208] The DCI format; the number of bits corresponding to the DCI; the Radio Network Temporary Identifier (RNTI) corresponding to the DCI; the encoding method corresponding to the DCI; the encoding rate corresponding to the DCI; the number of CCEs corresponding to the DCI; the aggregation level corresponding to the DCI; and the number of candidate PDCCHs associated with the aggregation level.

[0209] The number of bits corresponding to DCI corresponds to the maximum number of bits. The encoding methods include, but are not limited to, convolutional codes, Turbo codes, polar codes, low-density parity check (LDPC) codes, or small block length encoding.

[0210] 2) The second transmission resource is used to transmit the first downlink data.

[0211] In some embodiments, the second transport resource is used to transmit downlink data, which is carried by the PDSCH.

[0212] In some embodiments, the transmission parameters corresponding to downlink data are determined based on protocol predefined information or network configuration information.

[0213] In some embodiments, where the first indication information is used to indicate the transmission of first downlink data on a second transport resource, at least one of the following information is determined based on protocol predefined information or network configuration information:

[0214] The following information is provided: Transport Block Size (TBS) for the first downlink data; Modulation and Coding Scheme (MCS) level for the first downlink data; Coding scheme for the first downlink data; Coding rate for the first downlink data; MCS table for the first downlink data; Number of layers for the first downlink data; Antenna port information for the first downlink data; Rate matching information for the first downlink data; Number of Physical Resource Blocks (PRBs) included in the Resource Block Group; PRB binding size indication information; Transmission configuration indication message; DeModulation Reference Signal (DMRS) information for the first downlink data. The TBS can be configured by the network device. If the data packet to be transmitted is smaller than the TBS, the data packet size can be made equal to the TBS by padding with redundant bits.

[0215] Optionally, the DMRS information corresponding to the downlink data is determined through protocol predefined information or network configuration information. The DMRS information includes at least one of the following: the time domain location of the DMRS; the frequency domain location of the DMRS; the pattern of the DMRS; and DMRS sequence initialization information. Optionally, the DMRS information corresponding to the first downlink data is determined based on protocol predefined information, network configuration information, or first indication information.

[0216] In some embodiments, the second transmission resource is used only for transmitting small data packets, or the second transmission resource is used only for small data packet transmission (SDT).

[0217] 3) No transmission on the second transmission resource

[0218] In some embodiments, there is no transmission on the second transmission resource.

[0219] In some embodiments, the terminal determines whether there is transmission on the second transmission resource, or whether it is necessary to detect the second transmission resource, based on the detected first indication information. In this case, the indication content of the first indication information includes indication information that there is no transmission on the second transmission resource.

[0220] In some embodiments, the terminal determines whether there is a transmission on the second transmission resource, or whether it needs to detect the second transmission resource, based on whether the first indication information is detected. In this case, the presence or absence of transmission on the second transmission resource is determined by whether the first indication information is detected.

[0221] In some embodiments, the terminal detects first indication information on the first transmission resource, which indicates that there is no transmission on the second transmission resource. Therefore, the terminal does not need to perform detection on the second transmission resource.

[0222] In some embodiments, the terminal detects the first indication information on the first transmission resource. If the terminal does not detect the first indication information, it means that there is no transmission on the second transmission resource. Therefore, the terminal does not need to perform detection on the second transmission resource.

[0223] The transmission parameters on the second transmission resource are determined based on the first indication information and / or the first information associated with the first indication information.

[0224] In some embodiments, transmission parameters on the second transmission resource are determined based on first indication information and / or first information associated with the first indication information. That is, the transmission parameters on the second transmission resource are determined based on the first indication information; or, the transmission parameters on the second transmission resource are determined based on the first information associated with the first indication information; or, the transmission parameters on the second transmission resource are determined based on a combination of the first indication information and the first information.

[0225] In some embodiments, the first indication information is carried by a sequence or at least one bit. Determining the transmission parameters corresponding to the transmission content on the second transmission resource based on the first indication information can also be understood as determining the transmission parameters corresponding to the transmission content on the second transmission resource based on the sequence or at least one bit carrying the first indication information. Optionally, different sequences or different bits indicate the transmission parameters corresponding to different transmission contents on the second transmission resource.

[0226] In some embodiments, the first information includes at least one of the following: frequency domain resources corresponding to the first indication information, time domain resources corresponding to the first indication information, and first parameters corresponding to the first sequence carrying the first indication information. Optionally, the first parameters include at least one of the following: an initial value corresponding to the first sequence, a cyclic shift value corresponding to the first sequence, a group number corresponding to the first sequence, a root sequence number within the group corresponding to the first sequence, a sequence length corresponding to the first sequence, and a sequence index corresponding to the first sequence. The first sequence is used to carry the first indication information.

[0247] Taking the use of first indication information to indicate transmission parameters as an example, the first indication information is carried by a first sequence or at least one bit, and different values ​​of different first sequences or at least one bit can be used to indicate transmission parameters.

[0248] Taking the use of first information to indicate transmission parameters as an example, at least five different indication methods are given below for indicating the values ​​of transmission parameters corresponding to the transmission content on the second transmission resource. Among them, the first sequence is used to carry the first indication information.

[0249] Indication Method 1: Based on the length of the first sequence, indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0250] Instruction Method 2: Based on the frequency domain resources corresponding to the first instruction information, indicate the values ​​of the transmission parameters corresponding to the transmission content on the second transmission resource;

[0251] Instruction Method 3: Based on the time domain resource corresponding to the first instruction information, instruct the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0252] Indication Method 4: Based on the sequence index corresponding to the first sequence, indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0253] Indication Method 5: Based on the sequence group index corresponding to the first sequence, indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource.

[0254] For indication method one: the value of the transmission parameter corresponding to the transmission content on the second transmission resource is indicated based on the length corresponding to the first sequence;

[0255] For example, different lengths of the sequence correspond to different values, different states, or different sequences, thereby indicating different values ​​of the transmission parameters corresponding to the transmission content on the second transmission resource. In some embodiments, the first parameter associated with the first indication information includes the length of the sequence. The length of the sequence includes A1 values, and the transmission parameters (e.g., aggregation level, number of CCEs, number of resources, modulation scheme, MCS table, MCS level, TBS) include A2 values. There is an A-th correspondence between the length of the sequence and the values ​​of the transmission parameters. Optionally, the A-th correspondence is determined based on protocol predefined information or network configuration information. Wherein, A1 is an integer greater than or equal to 1, and A2 is an integer greater than or equal to 1.

[0256] For indication method two: based on the frequency domain resource indication corresponding to the first indication information, the values ​​of the transmission parameters corresponding to the transmission content on the second transmission resource are indicated;

[0257] For example, different frequency domain resources corresponding to the first indication information correspond to different values, different states, or different sequences, thereby indicating different values ​​of transmission parameters corresponding to the transmission content on the second transmission resource. In some embodiments, the first parameter associated with the first indication information includes the frequency domain resources corresponding to the first indication information. The number of frequency domain resources available for transmitting the first indication information is B1, and the values ​​of the transmission parameters (e.g., aggregation level, number of CCEs, number of resources, modulation scheme, MCS table, MCS level, TBS) include B2 values. There is a Bth correspondence between the frequency domain resources corresponding to the first indication information and the values ​​of the transmission parameters. Optionally, the Bth correspondence is determined based on protocol predefined information or network configuration information; wherein, B1 is an integer greater than or equal to 1, and B2 is an integer greater than or equal to 1. In some embodiments, B1 frequency domain resources available for transmitting the first indication information correspond to different frequency domain portions of the first transmission resource; or, B1 frequency domain resources available for transmitting the first indication information correspond to B1 first transmission resources, and the B1 first transmission resources are associated with the same second transmission resource. In some embodiments, different frequency domain offsets correspond to different values ​​of the transmission parameters.

[0258] For indication method three: based on the time domain resource corresponding to the first indication information, indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0259] For example, different time-domain resources corresponding to the first indication information correspond to different values, different states, or different sequences, thereby indicating different values ​​of the transmission parameters corresponding to the transmission content on the second transmission resource. In some embodiments, the first parameter associated with the first indication information includes the time-domain resource corresponding to the first indication information. The number of time-domain resources available for transmitting the first indication information is C1, and the values ​​of the transmission parameters include C2 values. There is a Cth correspondence between the time-domain resources corresponding to the first indication information and the values ​​of the transmission parameters. Optionally, the Cth correspondence is determined based on protocol predefined information or network configuration information; wherein, C1 is an integer greater than or equal to 1, and C2 is an integer greater than or equal to 1. In some embodiments, the time-domain resource includes a time slot or a time-domain symbol. Optionally, the granularity of the time-domain resource division may also include at least one of frame, subframe, mini-time slot, sub-time slot, symbol, symbol group, and unit based on other time-domain units.

[0260] For indication method four: based on the sequence index corresponding to the first sequence, indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0261] For example, the sequence index corresponding to the first sequence indicates different values ​​of the transmission parameters corresponding to the transmission content on the second transmission resource. In some embodiments, the first parameter associated with the first indication information includes the sequence index corresponding to the first sequence. The sequence index corresponding to the sequence includes D1 values, and the values ​​of the transmission parameters include D2 values. There is a Dth correspondence between the sequence index corresponding to the sequence and the values ​​of the transmission parameters, and the Dth correspondence is determined based on protocol predefined information or network configuration information; wherein, D1 is an integer greater than or equal to 1, and D2 is an integer greater than or equal to 1.

[0262] For indication method five: the value of the transmission parameter corresponding to the transmission content on the second transmission resource is indicated based on the sequence group index corresponding to the first sequence.

[0263] For example, different sequence groups corresponding to the first sequence correspond to different values, different states, or different sequences, thereby indicating different values ​​of the transmission parameters corresponding to the transmission content on the second transmission resource. In some embodiments, the first parameter associated with the first indication information includes the sequence group index corresponding to the first sequence. The sequence group index corresponding to the sequence includes E1 values, and the values ​​of the transmission parameters include E2 values. There is an Eth-order correspondence between the sequence group index corresponding to the sequence and the values ​​of the transmission parameters, and the Eth-order correspondence is determined based on protocol predefined information or network configuration information; wherein, E1 is an integer greater than or equal to 1, and E2 is an integer greater than or equal to 1. In some embodiments, a sequence group consists of one or more sequences, and the sequence group index is used to identify a sequence group, and the sequence group index is used to determine a set of related sequences.

[0264] Based on the first indication information and / or the first information associated with the first indication information, determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource.

[0265] In some embodiments, the value of the transmission parameter corresponding to the transmission content on the second transmission resource can be determined by the first indication information, thereby enabling link adaptive adjustment of the DCI or downlink data transmitted on the second transmission resource. When the transmission parameter corresponds to different values, the number or size of transmission resources required for the DCI or downlink data transmitted on the second transmission resource are also different.

[0266] In some embodiments, the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the first indication information; or, the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the first information associated with the first indication information; or, the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the information combination of the first indication information and the first information.

[0267] Taking the determination of resource location using the first information associated with the first indication information as an example, as shown in part (a) of Figure 8, if the size of the second transmission resource configured by the network device corresponds to the size of 8 CCEs, when the transmission parameter value is 2 CCEs, the DCI transmitted on the second transmission resource only needs to occupy 1 / 4 of the size of the second transmission resource. If the network device configures 4 UEs to share the second transmission resource, and the transmission parameter value of each UE is 2 CCEs, then the second transmission resource can be used to transmit the DCIs of these four UEs simultaneously at most. As shown in part (b) of Figure 8, the starting position of the transmission resource corresponding to the DCIs transmitted by these four UEs on the second transmission resource is configured by the network device.

[0268] In some embodiments, the terminal device receives first indication information on the first transmission resource, and determines the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first information associated with the first indication information. The downlink transmission content is the transmission content in the second transmission resource. The first indication information is used to indicate the transmission content on the second transmission resource and / or the value of the transmission parameters corresponding to the transmission content.

[0269] In some embodiments, the downlink transmission content is the transmission content within the second transmission resource, and the transmission resource corresponding to the downlink transmission content is a portion of the resources within the second transmission resource. Optionally, the second transmission resource includes n sub-resources, and the transmission resource corresponding to the downlink transmission content is the first sub-resource among the n sub-resources. The resource location of the transmission resource corresponding to the downlink transmission content is a location within the second transmission resource, that is, the location of the first sub-resource within the second transmission resource.

[0270] In some embodiments, the first indication information is carried by a sequence. The first information can also be replaced by information associated with the sequence, such as sequence information, sequence attribute information, or parameters corresponding to the sequence. This application does not limit this. Optionally, the first information includes at least one of the following: time-domain resources corresponding to the first indication information, frequency-domain resources corresponding to the first indication information, and first parameters corresponding to the sequence carrying the first indication information. The first parameters include at least one of the following: an initial value corresponding to the sequence, a cyclic shift value corresponding to the sequence, a group number corresponding to the sequence, a root sequence number within the group corresponding to the sequence, a sequence length corresponding to the sequence, and a sequence index corresponding to the sequence.

[0271] In some embodiments, there is a correspondence between the first information and the resource location. The terminal device determines the first information associated with the first indication information based on the first indication information received on the first transmission resource, and then determines the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource. In some embodiments, the resource location includes at least one of a resource start position, a resource end position, and a resource size. The resource start position includes at least one of a time-domain start position, a frequency-domain start position, and a logical resource start position. The resource end position includes at least one of a time-domain end position, a frequency-domain end position, and a logical resource unit end position. The resource size includes at least one of the number of time-domain units, the number of frequency-domain units, and the number of logical resource units.

[0272] Alternatively, there are eight different methods for determining the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource.

[0273] Method 1: Determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the time domain resource corresponding to the first indication information;

[0274] Method 2: Determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the frequency domain resource corresponding to the first indication information;

[0275] Method 3: Determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first parameter corresponding to the first indication information;

[0276] Method 4: Determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the time domain resources and frequency domain resources corresponding to the first indication information;

[0277] Method 5: Determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the time domain resource corresponding to the first indication information and the first parameter;

[0278] Method Six: Determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the frequency domain resource corresponding to the first indication information and the first parameter;

[0279] Method 7: Determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the time domain resource, frequency domain resource and first parameter corresponding to the first indication information;

[0280] Method 8: Determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first indication information.

[0281] Methods one through seven determine the resource location of the transmission resource corresponding to the downlink transmission content within the second transmission resource based on the first information associated with the first indication information. Method eight determines the resource location of the transmission resource corresponding to the downlink transmission content within the second transmission resource based on the first indication information.

[0282] The following explanation uses the example of determining the location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first information.

[0283] Regarding the first determination method mentioned above: In some embodiments, the first information includes the time-domain resource corresponding to the first indication information, and the first indication information transmitted on different first transmission resources is associated with different time-domain resources. It can also be understood that at least two first transmission resources are associated with different time-domain resources, or that a portion of the first transmission resources are associated with different time-domain resources. This application does not limit this.

[0284] In some embodiments, the first information includes time-domain resources corresponding to the sequence. The resource location is determined based on the time-domain resources corresponding to the first indication information and a first correspondence relationship, which includes the correspondence between time-domain resources and resource locations. In some embodiments, the first correspondence relationship, which includes the correspondence between time-domain resources and resource locations, can be understood as including the correspondence between time-domain resources and resource start positions, or the correspondence between time-domain resources and resource end positions, or the correspondence between time-domain resources and resource sizes. The first correspondence relationship is determined based on protocol predefined information or network configuration information. Optionally, the first correspondence relationship includes a one-to-one correspondence, a many-to-one correspondence, and a one-to-many correspondence.

[0285] For example, referring to Figure 9, the first indication information is carried by a sequence. The network device configures four first transmission resources for the terminal device, that is, the second transmission resources are associated with the four first transmission resources, and the sequence transmitted on the four first transmission resources is associated with four OFDM symbols. Each OFDM symbol can be used to transmit the sequence carrying the first indication information. As shown in part (a) of Figure 9, the second transmission resources include four time-domain start positions. The network device configures the first correspondence between the OFDM symbols for transmitting the first indication information and the time-domain start positions as a one-to-one correspondence. Optionally, when the OFDM symbol is 0, it corresponds to the time-domain start position A on the second transmission resource; when the OFDM symbol is 1, it corresponds to the time-domain start position B on the second transmission resource; when the OFDM symbol is 2, it corresponds to the time-domain start position C on the second transmission resource; and when the OFDM symbol is 3, it corresponds to the time-domain start position D on the second transmission resource. As shown in part (b) of Figure 9, the second transmission resources include four frequency-domain start positions. The network device is configured to have a one-to-one correspondence between the OFDM symbols and frequency domain start positions for transmitting the first indication information. Optionally, when the OFDM symbol is 0, it corresponds to frequency domain start position a on the second transmission resource; when the OFDM symbol is 1, it corresponds to frequency domain start position b on the second transmission resource; when the OFDM symbol is 2, it corresponds to frequency domain start position c on the second transmission resource; and when the OFDM symbol is 3, it corresponds to frequency domain start position d on the second transmission resource. As shown in part (c) of Figure 9, the second transmission resource includes four logical resource start positions, for example, four CCE start positions. The network device is configured to have a one-to-one correspondence between the OFDM symbols and logical resource start positions for transmitting the first indication information. Optionally, when the OFDM symbol is 0, the CCE index on the second transmission resource is 0; when the OFDM symbol is 1, the CCE index on the second transmission resource is 1; when the OFDM symbol is 2, the CCE index on the second transmission resource is 2; and when the OFDM symbol is 3, the CCE index on the second transmission resource is 3.

[0286] Regarding the second determination method described above: In some embodiments, the first information includes the frequency domain resource corresponding to the first indication, and the first indication information transmitted on different first transmission resources is associated with different frequency domain resources. This can also be understood as at least two first transmission resources being associated with different frequency domain resources, or a subset of first transmission resources being associated with different frequency domain resources. This application does not limit this.

[0287] In some embodiments, the first information includes frequency domain resources corresponding to the first indication information. The resource location is determined based on the frequency domain resources corresponding to the first indication information and a second correspondence. The second correspondence includes the correspondence between frequency domain resources and resource locations. This second correspondence can be understood as including the correspondence between frequency domain resources and resource start locations, or the correspondence between frequency domain resources and resource end locations, or the correspondence between frequency domain resources and resource sizes. The second correspondence is determined based on protocol predefined information or network configuration information. Optionally, the second correspondence includes a one-to-one correspondence, a many-to-one correspondence, and a one-to-many correspondence.

[0288] In some embodiments, the frequency domain resources of a sequence are characterized by at least one of the following parameters: the frequency domain start position of the frequency domain resources, the frequency domain offset of the frequency domain resources, and the frequency domain resource size.

[0289] In some embodiments, the frequency domain start position based on the frequency domain resources represents the frequency domain resources of the sequence, and there is a second correspondence between different frequency domain start positions and different resource positions on the second transmission resource, that is, there is a second correspondence between different frequency domain start positions of the first transmission resource and different resource positions on the second transmission resource. Optionally, there is a second correspondence between different frequency domain start positions and different resource start positions on the second transmission resource; or, there is a second correspondence between different frequency domain start positions and different resource end positions on the second transmission resource; or, there is a second correspondence between different frequency domain start positions and different resource sizes on the second transmission resource.

[0290] For example, referring to Figure 10, taking the transmission of first indication information via a sequence as an example, the network device configures four first transmission resources for the terminal device. That is, the second transmission resources are associated with the four first transmission resources, and the sequences transmitted on the four first transmission resources are associated with four frequency domain units, such as sub-bands. Each sub-band can be used to transmit a sequence carrying first indication information. As shown in part (a) of Figure 10, the second transmission resources include four time-domain start positions. The network device configures a one-to-one correspondence between the sub-bands transmitting the first indication information and the time-domain start positions. Optionally, when the sub-band is 0, it corresponds to the time-domain start position A on the second transmission resource; when the sub-band is 1, it corresponds to the time-domain start position B on the second transmission resource; when the sub-band is 2, it corresponds to the time-domain start position C on the second transmission resource; and when the sub-band is 3, it corresponds to the time-domain start position D on the second transmission resource. As shown in part (b) of Figure 10, the second transmission resources include four frequency-domain start positions. The network device configures a one-to-one correspondence between the sub-bands transmitting the first indication information and the frequency-domain start positions. Optionally, when the subband is 0, it corresponds to the frequency domain start position a on the second transmission resource; when the subband is 1, it corresponds to the frequency domain start position b on the second transmission resource; when the subband is 2, it corresponds to the frequency domain start position c on the second transmission resource; and when the subband is 3, it corresponds to the frequency domain start position d on the second transmission resource.

[0291] In some embodiments, the frequency domain offset based on the frequency domain resources characterizes the frequency domain resources of the sequence. Different frequency domain offsets have a second correspondence with different resource positions on the second transmission resource; that is, different frequency domain offsets of the first transmission resource have a second correspondence with different resource positions on the second transmission resource. Optionally, different frequency domain offsets have a second correspondence with different resource start positions on the second transmission resource; or, different frequency domain offsets have a second correspondence with different resource end positions on the second transmission resource; or, different frequency domain offsets have a second correspondence with different resource sizes on the second transmission resource. The sequence is mapped to the first transmission resource in a comb-like manner, and the frequency domain offset indicates the offset corresponding to the comb-like resource occupied by the sequence in the first transmission resource. The first transmission resource can be called a first comb-like resource. Optionally, the first transmission resource includes n frequency domain units, and the n frequency domain units in the first transmission resource are arranged in a comb-like pattern.

[0292] For example, as shown in Figure 11, taking the transmission of the first indication information via a sequence as an example, the network device configures four first transmission resources for the terminal device. That is, the second transmission resource is associated with the four first transmission resources. All four first transmission resources are comb-shaped frequency domain resources, and each comb-shaped frequency domain resource has a different frequency domain offset. For example, the frequency domain offset of comb-shaped frequency domain resource (a) is 0, the frequency domain offset of comb-shaped frequency domain resource (b) is 1, the frequency domain offset of comb-shaped frequency domain resource (c) is 2, and the frequency domain offset of comb-shaped frequency domain resource (d) is 3. Each comb-shaped frequency domain resource can be used to transmit the sequence carrying the first indication information. The second transmission resource includes four time domain start positions. The network device configures a one-to-one correspondence between the frequency domain offset and the time domain start positions. Optionally, when the frequency domain offset is 0, it corresponds to the time domain start position A on the second transmission resource; when the frequency domain offset is 1, it corresponds to the time domain start position B on the second transmission resource; when the frequency domain offset is 2, it corresponds to the time domain start position C on the second transmission resource; and when the frequency domain offset is 3, it corresponds to the time domain start position D on the second transmission resource.

[0293] In some embodiments, the frequency domain resource size (or sequence length) represents the frequency domain resources of the sequence, and there is a second correspondence between different frequency domain resource sizes and different resource positions on the second transmission resource; that is, there is a second correspondence between different frequency domain resource sizes of the first transmission resource and different resource positions on the second transmission resource. Optionally, there is a second correspondence between different frequency domain resource sizes and different resource start positions on the second transmission resource; or, there is a second correspondence between different frequency domain resource sizes and different resource end positions on the second transmission resource; or, there is a second correspondence between different frequency domain resource sizes and different resource sizes on the second transmission resource.

[0294] For example, referring to Figure 12, the network device configures four first transmission resources for the terminal device. That is, the second transmission resources are associated with the four first transmission resources, and the sequences transmitted on the four first transmission resources are associated with four frequency domain units, such as subbands. The sequence used to carry the first indication information can occupy different numbers of subbands, such as 1 subband, 2 subbands, and 4 subbands. Optionally, the longer the sequence carrying the first indication information, the more subbands it occupies. The second transmission resources include four frequency domain start positions. As shown in part (a) of Figure 12, the size of the frequency domain resource for transmitting the first indication information is 1 subband; as shown in part (b) of Figure 12, the size of the frequency domain resource for transmitting the first indication information is 2 subbands; and as shown in part (c) of Figure 12, the size of the frequency domain resource for transmitting the first indication information is 4 subbands. Optionally, when the frequency domain resource size is 1, that is, the sequence carrying the first indication information can occupy 1 sub-band, and the first indication information can be transmitted based on any one of the sub-bands from sub-band 0 to sub-band 3, corresponding to the frequency domain start position d on the second transmission resource; when the frequency domain resource size is 2, that is, the sequence carrying the first indication information can occupy 2 sub-bands, and the first indication information can be transmitted based on sub-band 0 and sub-band 1, or sub-band 1 and sub-band 2, or sub-band 2 and sub-band 3, corresponding to the frequency domain start position c on the second transmission resource; when the frequency domain resource size is 4, the first indication information can be transmitted based on sub-band 0, sub-band 1, sub-band 2 and sub-band 3, corresponding to the frequency domain start position a on the second transmission resource.

[0295] Regarding the third determination method mentioned above: In some embodiments, the first information includes a first parameter corresponding to the sequence carrying the first indication information, and sequences transmitted on different first transmission resources are associated with different first parameters. This can also be understood as at least two first transmission resources being associated with different first parameters, or a subset of first transmission resources being associated with different first parameters. This application does not limit this.

[0296] In some embodiments, the first information includes a first parameter corresponding to a sequence carrying first indication information. The resource location is determined based on the first parameter corresponding to the sequence and a third correspondence, which includes the correspondence between the first parameter and the resource location. This third correspondence can be understood as including the correspondence between the first parameter and the resource start position, or the correspondence between the first parameter and the resource end position, or the correspondence between the first parameter and the resource size. The third correspondence is determined based on protocol predefined information or network configuration information. Optionally, the third correspondence includes a one-to-one correspondence, a many-to-one correspondence, and a one-to-many correspondence.

[0297] Based on the first parameter corresponding to the detected sequence, the terminal can determine the resource location corresponding to the transmission resource of DCI or downlink data transmitted on the second transmission resource, such as the time-domain start position. Optionally, the network device configures a third correspondence between the first parameter and the time-domain start position on the second transmission resource, as shown in Table 5 below.

[0298] Table 5

[0299] For example, referring to Figure 13, the network device configures four first transmission resources for the terminal device; that is, the second transmission resources are associated with the four first transmission resources. The sequence transmitted on each first transmission resource is determined based on a different first parameter, and the sequences transmitted on the four first transmission resources are determined based on four first parameters. For example, the network device configures four sequences that can be used to carry first indication information, corresponding to sequence 0, sequence 1, sequence 2, and sequence 3, respectively. All four sequences can be transmitted on the first transmission resources. The second transmission resources include four time-domain start positions. Optionally, when the first parameter takes a first value, it corresponds to time-domain start position A on the second transmission resource; when the first parameter takes a second value, it corresponds to time-domain start position B on the second transmission resource; when the first parameter takes a third value, it corresponds to time-domain start position C on the second transmission resource; and when the first parameter takes a fourth value, it corresponds to time-domain start position D on the second transmission resource.

[0300] In some embodiments, the sequence carrying the first indication information is a pseudo-random sequence, which is determined based on the value of the parameter Cinit. Optionally, the network configures four Cinit values, for example, 17, 53, 127, and 131, and four sequences can be determined based on these four values. The second transmission resource includes four logical resource start positions, for example, the second transmission resource includes four CCE start positions. For example, these four sequences are used to indicate different aggregation levels corresponding to the DCI transmitted on the second transmission resource: aggregation level 1, aggregation level 2, aggregation level 4, and aggregation level 8, and the number of CCEs corresponding to aggregation level 1, aggregation level 2, aggregation level 4, and aggregation level 8 are 1, 2, 4, and 8, respectively. Optionally, the total number of CCEs used for transmitting DCI on the second transmission resource is 8, corresponding to CCE indices 0 to 7. Optionally, the network device configures a third correspondence between the value of the first parameter and the logical resource start position, that is, the network configures the correspondence between the value of Cinit and the start position of the CCE for transmitting DCI on the second transmission resource, as shown in Table 6 below.

[0301] Table 6

[0302] For example, the first information includes the first parameter corresponding to the sequence. The network device configures four first transmission resources for the terminal device, that is, the second transmission resource is associated with four first transmission resources. The sequence transmitted on each first transmission resource is determined based on different first parameters, and the sequence transmitted on the four first transmission resources is determined based on four first parameters. Among them, the CCE index indicates the starting position of the CCE. Optionally, the total number of CCEs used for transmitting DCI on the second transmission resource is 8, corresponding to indices 0 to 7 respectively. As shown in Table 6 above, when the value of the first parameter is 17 (corresponding to the first sequence), the aggregation level of the DCI it indicates is 1, that is, one CCE is needed to carry the DCI, and the CCE index on the second transmission resource is 7, and the DCI is mapped to the CCE with index 7; when the value of the first parameter is 53 (corresponding to the second sequence), the aggregation level of the DCI it indicates is 2, that is, two CCEs are needed to carry the DCI, and the CCE index on the second transmission resource is 4, and the DCI is mapped to two CCEs with indices 4 or 5; When the value of one parameter is 127 (corresponding to the third sequence), the aggregation level of the DCI indicated is 4, which means that 4 CCEs are needed to carry the DCI. The corresponding CCE index on the second transmission resource is 4, and the DCI is mapped to CCEs with indices 4, 5, 6, and 7. When the value of the first parameter is 151 (corresponding to the fourth sequence), the aggregation level of the DCI indicated is 8, which means that 8 CCEs are needed to carry the DCI. The corresponding CCE index on the second transmission resource is 0, and the DCI is mapped to 8 consecutive CCEs starting from index 0.

[0303] It should be noted that the above determination methods one to three respectively introduce the method of determining the resource location of the downlink transmission content on the second transmission resource based on the time domain resources, frequency domain resources and the first parameter corresponding to the first indication information. It should be understood that the above determination methods can be used in combination, and the combination results in determination methods four to seven, which will not be elaborated here.

[0304] The following explanation uses the example of determining the location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first indication information.

[0305] Regarding the above-mentioned determination method eight: In some embodiments, the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the first indication information. The resource location includes at least one of the following: resource start location, resource end location, and resource size.

[0306] In some embodiments, the first indication information is carried by a sequence, or the first indication information is carried by a bit sequence comprising L bits, where L is an integer greater than or equal to 1. Determining the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first indication information can also be understood as determining the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the sequence carrying the first indication information or at least one bit.

[0307] In some embodiments, the network device configures at least two first transmission resources corresponding to one second transmission resource, that is, one second transmission resource is associated with at least two first transmission resources. Each of the at least two first transmission resources can be used to transmit first indication information. Optionally, there is a correspondence between the first indication information and the resource location; this can also be understood as a correspondence between the sequence carrying the first indication information or at least one bit and the resource location. The eighth correspondence is determined based on protocol predefined information or network configuration information. Optionally, the eighth correspondence includes a one-to-one correspondence, a many-to-one correspondence, and a one-to-many correspondence.

[0308] For example, taking the first indication information as a sequence carrier, sequence 0 represents resource location 0, sequence 1 represents resource location 1, and sequence 2 represents resource location 2.

[0309] The following explanation uses the example of determining the location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first indication information and the first information.

[0310] In some embodiments, the combination of the first indication information and the first information associated with the first indication information has a correspondence with the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource. Based on the combination of the first indication information and the first information, the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined.

[0311] In some embodiments, the first information associated with the first indication information includes at least one of the time-domain resources corresponding to the first indication information, the frequency-domain resources corresponding to the first indication information, and the first parameters corresponding to the sequence carrying the first indication information. The first parameters include at least one of the following: the initial value corresponding to the sequence, the cyclic shift value corresponding to the sequence, the group number corresponding to the sequence, the root sequence number within the group corresponding to the sequence, the sequence length corresponding to the sequence, and the sequence index corresponding to the sequence.

[0312] Optionally, the first information can be considered to have eight types, namely, the first information includes at least one of the following: time domain resources corresponding to the first indication information, frequency domain resources corresponding to the first indication information, initial value corresponding to the sequence, cyclic shift value corresponding to the sequence, group number corresponding to the sequence, root sequence number within the group corresponding to the sequence, sequence length corresponding to the sequence, and sequence index corresponding to the sequence.

[0313] In some embodiments, the first indication information is carried by a sequence. Based on the combination of the first indication information and at least one type of first information, the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined. This can be understood as determining the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the combination of the sequence carrying the first indication information and the first information. The at least one type of first information can be considered to be at least one of the eight types of information mentioned above.

[0314] For example, taking the first information as the time-domain resource corresponding to the first indication information, the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the information combination of the first indication information and the time-domain resource. For example, sequence 0 and the time-domain position 0 of the first transmission resource represent resource position 0 in the second transmission resource; sequence 0 and the time-domain position 1 of the first transmission resource represent resource position 1 in the second transmission resource; sequence 1 and the time-domain position 0 of the first transmission resource represent resource position 2 in the second transmission resource; and sequence 1 and the time-domain position 1 of the first transmission resource represent resource position 3 in the second transmission resource.

[0315] It should be noted that, based on the combination of the first indication information and the first information, the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource can be determined by combining at least one of the above-mentioned "for determination method eight" and "for determination methods one to seven", which will not be elaborated here.

[0316] Repeatedly transmit the first indication information on at least two first transmission resources.

[0317] In related technologies, a terminal device constantly in a detection state consumes its energy, and it cannot determine the transmission resources corresponding to downlink data. In this application, the network device configures a first transmission resource to transmit first indication information, and the terminal device determines the transmission information on a second transmission resource by receiving the first indication information. However, in situations with poor signal strength, the terminal device may not be able to accurately receive the first indication information. Therefore, this application configures multiple first transmission resources to repeatedly transmit the first indication information. This method helps improve the reception success rate and the reliability of the first indication information detection.

[0318] In some embodiments, the terminal device receives first information sent by the network device. The first information is used to configure or indicate at least two first transmission resources. The at least two first transmission resources are used to repeatedly transmit first indication information. The first indication information and / or the first information associated with the first indication information are used to indicate transmission information on a second transmission resource.

[0319] In some embodiments, the transmission resources configured by the network device for the terminal device include at least a first transmission resource and a second transmission resource. Optionally, the first transmission resource and the second transmission resource have a many-to-one relationship, that is, multiple first transmission resources correspond to one second transmission resource, or it can be understood that one second transmission resource is associated with multiple first transmission resources. The aforementioned at least two first transmission resources are all or part of the multiple first transmission resources. Optionally, the multiple first transmission resources are divided into at least two groups, and the at least two first transmission resources are one of the at least two groups of first transmission resources.

[0320] In some embodiments, at least two sets of first transmission resources satisfy at least one of the following: the time-domain resources corresponding to the at least two sets of first transmission resources are different; the frequency-domain resources corresponding to the at least two sets of first transmission resources are different; the sequences transmitted on the at least two sets of first transmission resources are different, wherein the sequences are used to carry first indication information.

[0321] For example, referring to Figure 14, the first indication information is carried by a sequence. As shown in part (a) of Figure 14, the network device configures four first transmission resources for the terminal device. The four first transmission resources correspond to different time-domain resources. For example, the sequence transmitted on the four first transmission resources is associated with four OFDM symbols, and each OFDM symbol can be used to transmit the sequence carrying the first indication information. The network device is configured to repeatedly transmit the sequence 0 carrying the first indication information on all or part of the four first transmission resources. For example, the sequence 0 is repeatedly transmitted on all four first transmission resources.

[0322] As shown in part (b) of Figure 14, the network device configures four first transmission resources for the terminal device. The four first transmission resources correspond to different frequency domain resources. For example, the sequences transmitted on the four first transmission resources are associated with four sub-bands, and each sub-band can be used to transmit a sequence carrying first indication information. The network device is configured to repeatedly transmit the sequence 0 carrying the first indication information on all or part of the four first transmission resources. For example, taking the frequency domain positions arranged from top to bottom as an example, the sequence 0 is repeatedly transmitted on the first transmission resource with the highest frequency position and the first transmission resource with the lowest frequency position.

[0323] As shown in part (c) of Figure 14, the network device configures four first transmission resources for the terminal device. The sequences transmitted on these four first transmission resources are different; for example, the sequences transmitted on the four first transmission resources may be associated with two OFDM symbols. Each OFDM symbol includes two sub-bands, and each sub-band on each symbol can be used to transmit a sequence carrying first indication information. The network device is configured to repeatedly transmit sequence 0 carrying the first indication information on all or part of the four first transmission resources. For example, taking the frequency domain positions arranged from top to bottom, sequence 0 is repeatedly transmitted on the first transmission resource at the highest frequency position of the first symbol (symbol 0) and the first transmission resource at the lowest frequency position of the second symbol (symbol 1). The network device repeatedly transmits the first indication information on at least two first transmission resources, thereby improving the reliability of the first indication information detection.

[0324] In some embodiments, the first information is used to configure or indicate the quantity and location of at least two first transmission resources. Optionally, the first information includes index information, which is used to configure or indicate the quantity and location of at least two first transmission resources. The index information corresponds to at least two first transmission resources. In some embodiments, the network device configures N first transmission resources corresponding to second transmission resources for the terminal device; that is, the second transmission resources are associated with N first transmission resources, where N is a positive integer greater than 1. Optionally, the index information corresponding to the N first transmission resources is 0, 1, 2, 3, ..., N-1.

[0325] For example, as shown in part (a) of Figure 14, the index information corresponding to the first transmission resources on the four symbols from left to right is 0, 1, 2, 3, that is, symbol 0 corresponds to index 0, symbol 1 corresponds to index 1, symbol 2 corresponds to index 2, and symbol 3 corresponds to index 3.

[0326] As shown in part (b) of Figure 14, the index information corresponding to the first transmission resources on the four sub-bands from bottom to top is 0, 1, 2, 3, that is, sub-band 0 corresponds to index 0, sub-band 1 corresponds to index 1, sub-band 2 corresponds to index 2, and sub-band 3 corresponds to index 3.

[0327] As shown in part (c) of Figure 14, the first transmission resources on the four symbols are indexed in the order of frequency domain first and then time domain (or time domain first and then frequency domain). The corresponding index information is 0, 1, 2, 3, that is, the lowest position of the frequency domain on symbol 0 corresponds to index 0, the highest position of the frequency domain on symbol 0 corresponds to index 1, the lowest position of the frequency domain on symbol 1 corresponds to index 2, and the highest position of the frequency domain on symbol 1 corresponds to index 3.

[0328] In some embodiments, the first information includes index information, which corresponds to at least two first transmission resources. That is, when the index information is X, it corresponds to at least two first transmission resources. This can be understood as follows: when the index information is X, the first indication information is transmitted through the at least two first transmission resources corresponding to the index information, where X is a positive integer. The correspondence between the network device configuration index information and the first transmission resources (based on the first transmission resource index representation) is shown in Table 7 below.

[0329] Table 7

[0330] For example, the first information is used to configure or indicate at least one first transmission resource, which is used to transmit the first indication information. The first information includes index information, which corresponds to the first transmission resource.

[0331] Optionally, when the index information is 0, the corresponding first transmission resource is index 0, that is, the first indication information is transmitted through the first transmission resource of index 0; when the index information is 1, the corresponding first transmission resource is index 1, that is, the first indication information is transmitted through the first transmission resource of index 1; when the index information is 2, the corresponding first transmission resource is index 2, that is, the first indication information is transmitted through the first transmission resource of index 2; when the index information is 3, the corresponding first transmission resource is index 3, that is, the first indication information is transmitted through the first transmission resource of index 3.

[0332] When the index information is 0 to 3, the number of configured or indicated first transmission resources is 1, that is, the first indication information is transmitted on a first transmission resource.

[0333] For example, the first information is used to configure or indicate at least two first transmission resources, which are used to repeatedly transmit the first indication information. The first information includes index information, which corresponds to the at least two first transmission resources.

[0334] Optionally, when the index information is 4, the corresponding first transmission resources are index 0 and index 1. That is, the first indication information is transmitted through the first transmission resource of index 0, and the first indication information is repeatedly transmitted through the first transmission resource of index 1. This can also be understood as the first indication information being repeatedly transmitted twice through the first transmission resources of index 0 and index 1. When the index information is 5, the corresponding first transmission resources are index 0 and index 2. That is, the first indication information is repeatedly transmitted twice through the first transmission resources of index 0 and index 2, and so on.

[0335] When the index information is 4 to 9, the number of configured or indicated first transmission resources is 2, that is, the first indication information is repeatedly transmitted on two first transmission resources.

[0336] Optionally, when the index information is 10, the corresponding first transmission resources are index 0, index 1 and index 2, that is, the first indication information is repeatedly transmitted 3 times through the first transmission resources of index 0, index 1 and index 2...

[0337] When the index information is 10 to 13, the number of configured or indicated first transmission resources is 3, that is, the first indication information is repeatedly transmitted on three first transmission resources.

[0338] Optionally, when the index information is 14, the corresponding first transmission resources are index 0, index 1, index 2 and index 3, that is, the first indication information is repeatedly transmitted 4 times through the first transmission resources of index 0, index 1, index 2 and index 3.

[0339] When the index information is 14, the number of configured or indicated first transmission resources is 4, that is, the first indication information is repeatedly transmitted on four first transmission resources.

[0340] It should be noted that Table 7 above is merely an exemplary illustration of the correspondence between index information and the first transmission resource index, and the method implemented in this application is not limited to the correspondence in Table 7. In some embodiments, the correspondence of network configuration only includes a portion of the content in the table above, such as only including any two rows in the table above; in some embodiments, the correspondence of network configuration includes K index information items, and the corresponding first transmission resource indexes are L, where K and L are integers greater than or equal to 1.

[0341] In some embodiments, the network device configures the correspondence between index information and at least two first transmission resources based on broadcast information or RRC signaling. Optionally, the first information is carried in at least one of the following messages: RRC; MAC CE; DCI. The terminal device receives the first information and determines the number and location of at least two first transmission resources for repeated transmission based on the index information in the first information. Optionally, the network device configures the correspondence between the index information and the two first transmission resources based on broadcast information or RRC signaling as shown in Table 8 below.

[0342] Table 8

[0343] For example, the first information includes index information. For instance, when the index information is 0, the corresponding first transmission resources are index 0 and index 1, meaning that the first indication information is repeatedly transmitted twice using the first transmission resources of index 0 and index 1. Referring to part (a) of Figure 14, index 0 corresponds to symbol 0, and index 1 corresponds to symbol 1, meaning that the first indication information is repeatedly transmitted using the first transmission resources on symbols 0 and 1. When the first indication information is based on a sequence, repeatedly transmitting the first indication information using the first transmission resources on symbols 0 and 1 can also be understood as repeatedly transmitting the sequence carrying the first indication information using the first transmission resources on symbols 0 and 1. Optionally, the terminal device receives the first information sent by the network device and determines, based on the first information, whether to detect the first indication information on the first transmission resource of symbol 0, or on the first transmission resource of symbol 1, or on the first transmission resources of both symbols 0 and 1. Optionally, the terminal device performs combined detection on the first transmission resources of symbols 0 and 1.

[0344] As can be seen from the above examples, the first transmission resource can be used to repeatedly transmit the first indication information. The first indication information transmitted on the first transmission resource and / or the first information associated with the first indication information can be used to indicate the transmission content on the second transmission resource, or to indicate the transmission parameters corresponding to the transmission content on the second transmission resource, or to indicate the resource position of the transmission resource corresponding to the transmission content on the second transmission resource.

[0345] The above embodiments repeatedly utilize the association relationships (or correspondence relationships) configured by network devices. For example, in "Regarding the above determination method three," Table 5 shows the association relationship between the first parameter and the resource location corresponding to the sequence carrying the first indication information, and Table 6 shows the association relationship between the first parameter and the transmission parameters corresponding to the sequence carrying the first indication information. The terminal device can determine one type of information from another through the association relationships configured by the network device. For the terminal device, obtaining the association relationships between different types of information is crucial. The following describes how the network device configures these association relationships.

[0346] Figure 15 illustrates a flowchart of a resource configuration method provided by some exemplary embodiments of this application. The method is illustrated illustratively, taking the execution of the method by a terminal device as an example. The method includes:

[0347] Step 910: Receive first configuration information, which is used to configure at least two types of indication information and the association between the at least two types of indication information.

[0348] In some embodiments, the terminal device receives first configuration information sent by the network device. The first configuration information is used to configure at least two types of indication information, which can be understood as the first configuration information being used to configure at least two types of indication information that are of different types.

[0349] In some embodiments, the first configuration information is further used to configure the association relationship between at least two types of indication information. For example, there are multiple instances of each type of indication information, and there is a one-to-many, many-to-one, or many-to-many association relationship between the two types of indication information. At least two types of indication information are related to a first transmission resource and a second transmission resource. This association relationship can also be referred to as a correspondence relationship.

[0350] In some embodiments, the first configuration information is carried in at least one of the following messages: RRC signaling; MAC CE; DCI signaling.

[0351] In some embodiments, at least two types of indication information include at least two of the following:

[0352] • First transmission resource indication information, which is used to indicate the resource information of the first transmission resource;

[0353] • Sequence indication information, which is used to determine the sequence transmitted on the first transmission resource, the sequence is used to carry first indication information, and the first indication information is used to indicate the transmission information of the second transmission resource;

[0354] • Repeat transmission indication information, which is used to indicate at least two first transmission resources for repeating the first indication information;

[0355] • Transmission content indication information, which is used to indicate the transmission content of the second transmission resource;

[0356] • Transmission parameter indication information, which is used to indicate the transmission parameters corresponding to the transmission content of the second transmission resource;

[0357] • Resource location indication information: This information is used to indicate the resource location of the transmission resource corresponding to the transmission content on the second transmission resource.

[0358] In some embodiments, the first configuration information configures a relationship between at least two types of indication information. This can also be understood as a relationship between the information indicated by the first configuration information and the content indicated by the at least two types of indication information. For example, if the first configuration information configures at least two types of indication information including first transmission resource indication information and resource location indication information, configuring a relationship between the first transmission resource indication information and resource location indication information can also be understood as configuring a relationship between the first transmission resource and the resource location.

[0359] In some embodiments, before receiving the first configuration information, the terminal device also receives second configuration information sent by the network device. This can also be understood as the terminal device acquiring the second configuration information sent by the network device. The second configuration information is used to configure at least one set of transmission resources. The set of transmission resources includes at least a first transmission resource and a second transmission resource that are associated with each other, and the second transmission resource is associated with at least one first transmission resource. Optionally, the first configuration information and the second configuration information are the same configuration information, or the first configuration information and the second configuration information are the same configuration information, or the first configuration information and the second configuration information are independent configuration information. This application does not limit this.

[0360] In some embodiments, the first transmission resource and the second transmission resource are associated. Optionally, the first transmission resource and the second transmission resource belong to a set of transmission resources configured by the network device. Here, a set of transmission resources refers to configuring the first transmission resource and the second transmission resource together. Optionally, a second transmission resource is associated with at least one first transmission resource, which can be understood as a second transmission resource being associated with at least one first transmission resource within a set of transmission resources. Optionally, the association between the second transmission resource and the first transmission resource is reflected in at least one of the following: the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the locations of the second transmission resource and the first transmission resource based on a communication protocol; or, there is a pre-configured relationship between the locations of the second transmission resource and the first transmission resource based on network configuration.

[0361] In some embodiments, the first transmission resource is used to transmit first indication information. Optionally, the first indication information is carried by a sequence, or by at least one bit.

[0362] In some embodiments, the second transmission resource is a transmission resource configured by the network device for the terminal device, and the second transmission resource is used for downlink transmission. Optionally, the second transmission resource is used to transmit downlink control information and / or downlink data.

[0363] In summary, the method provided in this application embodiment involves a network device sending first configuration information to configure the association between at least two types of indication information. By flexibly configuring the association between at least two types of indication information, the network device can reduce the number of signaling messages that need to be transmitted separately and improve resource utilization efficiency.

[0364] Furthermore, at least two types of indication information in the first configuration information are related to the first transmission resource and the second transmission resource. Relative to the terminal device, the terminal device receives the first configuration information sent by the network device, and through the association between the at least two types of indication information in the first configuration information, determines the implicit indication information based on the association in the subsequent transmission process, thereby reducing the amount of control signaling required in the subsequent transmission process.

[0365] Figure 16 illustrates a flowchart of a resource configuration method provided by some exemplary embodiments of this application. The method is illustrated illustratively, taking the execution of the method by a network device as an example. The method includes:

[0366] Step 1010: Send first configuration information, which is used to configure at least two types of indication information and the association between the at least two types of indication information.

[0367] In some embodiments, the network device sends first configuration information to the terminal device. The first configuration information is used to configure at least two types of indication information. This can be understood as the first configuration information being used to configure at least two types of indication information that are of different types.

[0368] In some embodiments, the first configuration information is further used to configure the association relationship between at least two types of indication information. For example, there are multiple instances of each type of indication information, and there is a one-to-many, many-to-one, or many-to-many association relationship between the two types of indication information. At least two types of indication information are related to a first transmission resource and a second transmission resource. This association relationship can also be referred to as a correspondence relationship.

[0369] In some embodiments, the first configuration information is carried in at least one of the following messages: RRC signaling; MAC CE; DCI signaling.

[0370] In some embodiments, at least two types of indication information include at least two of the following:

[0371] • First transmission resource indication information, which is used to indicate the resource information of the first transmission resource;

[0372] • Sequence indication information, which is used to determine the sequence transmitted on the first transmission resource, the sequence is used to carry first indication information, and the first indication information is used to indicate the transmission information of the second transmission resource;

[0373] • Repeat transmission indication information, which is used to indicate at least two first transmission resources for repeating the first indication information;

[0374] • Transmission content indication information, which is used to indicate the transmission content of the second transmission resource;

[0375] • Transmission parameter indication information, which is used to indicate the transmission parameters corresponding to the transmission content of the second transmission resource;

[0376] • Resource location indication information: This information is used to indicate the resource location of the transmission resource corresponding to the transmission content on the second transmission resource.

[0377] In some embodiments, the first configuration information configures a relationship between at least two types of indication information. This can also be understood as a relationship between the information indicated by the first configuration information and the content indicated by the at least two types of indication information. For example, if the first configuration information configures at least two types of indication information including first transmission resource indication information and resource location indication information, configuring a relationship between the first transmission resource indication information and resource location indication information can also be understood as configuring a relationship between the first transmission resource and the resource location.

[0378] In some embodiments, before receiving the first configuration information, the network device further sends second configuration information to the terminal device. The second configuration information is used to configure at least one set of transmission resources, and the set of transmission resources includes at least a first transmission resource and a second transmission resource that are associated with each other, with the second transmission resource associated with at least one first transmission resource. Optionally, the first configuration information and the second configuration information are the same configuration information, or the first configuration information and the second configuration information are the same configuration information, or the first configuration information and the second configuration information are independent configuration information. This application does not limit this.

[0379] In some embodiments, the first transmission resource and the second transmission resource are associated. Optionally, the first transmission resource and the second transmission resource belong to a set of transmission resources configured by the network device. Here, a set of transmission resources refers to configuring the first transmission resource and the second transmission resource together. Optionally, a second transmission resource is associated with at least one first transmission resource, which can be understood as a second transmission resource being associated with at least one first transmission resource within a set of transmission resources. Optionally, the association between the second transmission resource and the first transmission resource is reflected in at least one of the following: the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the locations of the second transmission resource and the first transmission resource based on a communication protocol; or, there is a pre-configured relationship between the locations of the second transmission resource and the first transmission resource based on network configuration.

[0380] In some embodiments, the first transmission resource is used to transmit first indication information. Optionally, the first indication information is carried by a sequence, or by at least one bit.

[0381] In some embodiments, the second transmission resource is a transmission resource configured by the network device for the terminal device, and the second transmission resource is used for downlink transmission. Optionally, the second transmission resource is used to transmit downlink control information and / or downlink data.

[0382] In summary, the method provided in this application embodiment involves a network device sending first configuration information to configure the association between at least two types of indication information. By flexibly configuring the association between at least two types of indication information, the network device can reduce the number of signaling messages that need to be transmitted separately and improve resource utilization efficiency.

[0383] Furthermore, at least two types of indication information in the first configuration information are related to the first transmission resource and the second transmission resource. Relative to the terminal device, the terminal device receives the first configuration information sent by the network device, and through the association between the at least two types of indication information in the first configuration information, determines the implicit indication information based on the association in the subsequent transmission process, thereby reducing the amount of control signaling required in the subsequent transmission process.

[0384] Next, based on the embodiments shown in Figures 15 and 16, at least two types of indication information in the first configuration information will be further introduced.

[0385] In some embodiments, the first configuration information sent by the network device is used to configure at least two types of indication information and the association between the at least two types of indication information. The indication information in the at least two types of indication information can be considered to be indication information of different types belonging to the first indication information.

[0386] Among them, at least two types of indication information include at least two of the following types of indication information:

[0387] The first type: First transmission resource indication information, which is used to indicate the resource information of the first transmission resource;

[0388] The second type: sequence indication information. The sequence indication information is used to determine the sequence transmitted on the first transmission resource. The sequence is used to carry the first indication information, which is used to indicate the transmission information of the second transmission resource.

[0389] The third type: Repeat transmission indication information, which is used to indicate at least two first transmission resources for repeating the first indication information;

[0390] The fourth type: Transmission content indication information, which is used to indicate the transmission content of the second transmission resource;

[0391] The fifth type: transmission parameter indication information, which is used to indicate the transmission parameters corresponding to the transmission content of the second transmission resource;

[0392] The sixth type: resource location indication information. Resource location indication information is used to indicate the resource location of the transmission resource corresponding to the transmission content on the second transmission resource.

[0393] The different types of indication information in the first configuration information are described below.

[0394] For the first transmission resource indication information (first type):

[0395] In some embodiments, the first configuration information is used at least to configure first transmission resource indication information, which indicates the resource information of the first transmission resource. Optionally, the resource information of the first transmission resource includes, but is not limited to, at least one of the time-domain resource information, frequency-domain resource information, and index information of the first transmission resource.

[0396] In some embodiments, the first configuration information is used to configure the association between at least two types of indication information. Optionally, the first configuration information is used to configure the association between first transmission resource indication information and other types of indication information.

[0397] In some embodiments, the first configuration information is used to configure the association between a first transmission resource indication information and other types of indication information. These other types of indication information include at least one type. For example, configuring the association between the first transmission resource indication information and resource location indication information.

[0398] In some embodiments, the first configuration information is used to configure the association between a plurality of first transmission resource indication information and other types of indication information.

[0424] For example, the sequence carrying the first indication information is a pseudo-random sequence, that is, the sequence is generated or determined based on a pseudo-random sequence. For example, the pseudo-random sequence is c(n), and the length of the pseudo-random sequence is M. pn The pseudo-random sequence is determined by the following formula (1): c(n)=(x1(n+N) C )+x2(n+NC ))mod2 (1) x1(n+31)=(x1(n+3)+x1(n))mod2 x2(n+31)=(x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod2

[0428] In some embodiments, the sequence used to carry the first indication information is obtained by cyclically shifting a base sequence, wherein the cyclic shift value corresponding to the cyclic shifting is determined based on the cyclic shift value indication information.

[0429] For example, the first indication information is carried by a sequence, which is determined by the following formula (2):

[0430] in, Let M represent the base sequence, α represent the cyclic shift, and the value of α corresponds to the cyclic shift value. ZC Indicates the sequence length.

[0431] 3) Group number indication information corresponding to the sequence

[0432] In some embodiments, the sequence indication information includes group number indication information corresponding to the sequence, which is used to determine the group number to which the sequence corresponds. In some embodiments, the sequences are divided into different groups (or sets), and the group number indication information is used to explicitly identify the group number associated with the sequence.

[0433] For example, the first indication information is carried by a sequence, which is determined by the following formula (2):

[0434] in, Let M represent the base sequence, α represent the cyclic shift, and the value of α corresponds to the cyclic shift value. ZC Indicates the sequence length.

[0435] Optionally, base sequence The data is divided into multiple groups, where u∈{0,1,...,29} represents the group number; the value of u can be determined based on the group number information.

[0436] 4) Indication information for the base sequence number corresponding to the sequence.

[0437] In some embodiments, the sequence indication information includes base sequence number indication information corresponding to the sequence, which is used to determine the base sequence number corresponding to the sequence. The base sequence is typically a predefined or network-preconfigured basic sequence, and other complex sequences can be generated through encoding, modulation, etc. The base sequence number is an identifier used to identify the base sequence.

[0438] For example, the first indication information is carried by a sequence, which is determined by the following formula (2):

[0439] Among them, M ZC Indicates the sequence length. Let represent the base sequence (or root sequence), u represent the group number (e.g., u∈{0,1,...,29}), v represent the base sequence number within the group, and α represent the cyclic shift value. Optionally, the value of α in the above formula is determined based on the cyclic shift value indication information corresponding to the sequence, the value of u is determined based on the group number indication information corresponding to the sequence, and the value of v is determined based on the base sequence number indication information corresponding to the sequence.

[0440] 5) Sequence length indication information corresponding to the sequence.

[0441] In some embodiments, the sequence indication information includes sequence length indication information corresponding to the sequence, which is used to determine the length of the sequence.

[0442] For example, taking the sequence "10110101" as an example, the sequence length indicator information indicates that the sequence length is 8. Optionally, when the sequence is determined based on the pseudo-random sequence of the above formula (1), the sequence length corresponds to M. PN When the sequence is determined based on the sequence in formula (2) above, the sequence length corresponds to M. ZC M can be determined based on the sequence length indication information corresponding to the sequence. PN Or M ZC .

[0443] 6) Sequence index indication information corresponding to the sequence.

[0444] In some embodiments, the sequence indication information includes sequence index indication information corresponding to the sequence. The sequence index indication information is associated with a sequence and is used to determine the index information of the sequence. For example, a network device configures N sequences for transmitting first indication information, and indexes each sequence, with index numbers n = 0, 1, ..., N-1. The first configuration information sent by the network device includes the sequence index indication information, and the sequence transmitted on the first transmission resource can be determined based on the index indication information.

[0445] In some embodiments, the first configuration information sent by the network device is used to configure the first transmission resource indication information and the sequence indication information, as well as to configure the association between the first transmission resource indication information and the sequence indication information. The association can also be understood as a correspondence.

[0446] In some embodiments, the first configuration information configures a correspondence between the first transmission resource indication information and the sequence indication information. Optionally, the correspondence between the first transmission resource indication information and the sequence indication information includes a one-to-one correspondence, i.e., one first transmission resource corresponds to one sequence; or, the correspondence between the first transmission resource indication information and the sequence indication information includes a one-to-many correspondence, i.e., one first transmission resource corresponds to multiple sequences; or, the correspondence between the first transmission resource indication information and the sequence indication information includes a many-to-one correspondence, i.e., multiple first transmission resources correspond to one sequence; or, the correspondence between the first transmission resource indication information and the sequence indication information includes a many-to-many correspondence, i.e., multiple first transmission resources correspond to multiple sequences.

[0447] For example, a network device configures two first transmission resources, denoted as first transmission resource A and first transmission resource B, respectively. The sequences transmitted on these first transmission resources are a first sequence, a second sequence, a third sequence, and a fourth sequence, respectively. The first sequence, second sequence, third sequence, and fourth sequence are determined based on the values ​​corresponding to the sequence indication information. For instance, if the correspondence between the first transmission resource indication information and the sequence indication information includes a one-to-one correspondence, the network device can configure first transmission resource A to be associated with the first sequence, and first transmission resource B to be associated with the second sequence. Alternatively, if the correspondence between the first transmission resource indication information and the sequence indication information includes a one-to-many correspondence, the network device can configure first transmission resource A to be associated with the first sequence and the second sequence, and first transmission resource B to be associated with the third and fourth sequences. Furthermore, if the correspondence between the first transmission resource indication information and the sequence indication information includes a many-to-one correspondence, the network device can configure first transmission resource A and first transmission resource B to be associated with the first sequence. For example, when the correspondence between the first transmission resource indication information and the sequence indication information includes a many-to-many correspondence, the network device can configure the first transmission resource A to be associated with the first sequence and the second sequence, and the first transmission resource B to be associated with the first sequence and the second sequence.

[0448] For duplicate transmission indication information (third type):

[0449] In some embodiments, the first configuration information is used to configure at least repeat transmission indication information. The repeat transmission indication information indicates at least two first transmission resources used for repeatedly transmitting the first indication information. Alternatively, it can be understood that the repeat transmission indication information indicates at least two first transmission resources used for repeatedly transmitting the same first indication information. The at least two first transmission resources are transmission resources configured by the network device for the terminal device. Optionally, the transmission resources include, but are not limited to, resources in at least one dimension of time-domain resources, frequency-domain resources, code-domain resources, and spatial-domain resources.

[0450] Optionally, at least two first transmission resources correspond to different time-domain resources, and each of the different time-domain resources can be used to transmit the same first indication information. Optionally, at least two first transmission resources correspond to different frequency-domain resources, and each of the different frequency-domain resources can be used to transmit the same first indication information. Optionally, at least two first transmission resources correspond to different logical resource units, and each of the different logical resource units can be used to transmit the same first indication information. Optionally, at least two first transmission resources transmit different sequences, and each of the different sequences can be used to carry the same first indication information.

[0451] For example, the first transmission resource indication information in the first configuration information is used to indicate K first transmission resources, where K is an integer greater than or equal to 1; the value corresponding to the sequence indication information in the first configuration information is used to determine a sequence, denoted as the first sequence. The same first sequence is transmitted on K first transmission resources. When K is greater than 1, it means that the first sequence is repeatedly transmitted on multiple first transmission resources.

[0452] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and has a corresponding relationship with the repeated transmission indication information. The corresponding relationship includes a one-to-one correspondence; or a one-to-many correspondence; or a many-to-one correspondence; or a many-to-many correspondence.

[0453] For transmission content indication information (fourth type):

[0454] In some embodiments, the first configuration information is used at least to configure transmission content indication information, which is used to indicate the transmission content of the second transmission resource.

[0455] In some embodiments, the transmission content of the second transmission resource includes, but is not limited to, no transmission on the second transmission resource; transmission of DCI on the second transmission resource; transmission of downlink data on the second transmission resource; and transmission of at least one of DCI and downlink data on the second transmission resource.

[0456] For example, in some embodiments, the content transmitted on the second transmission resource includes no transmission, transmission of DCI, transmission of downlink data, and transmission of downlink data and DCI. In other embodiments, the content transmitted on the second transmission resource includes transmission of DCI, transmission of downlink data, and transmission of downlink data and DCI. In this case, if the first indication information is not detected on the first transmission resource, the terminal does not need to perform detection on the second transmission resource. In other embodiments, the content transmitted on the second transmission resource includes no transmission, transmission of DCI, and transmission of downlink data. In other embodiments, the content transmitted on the second transmission resource includes transmission of DCI and transmission of downlink data. In this case, if the first indication information is not detected on the first transmission resource, the terminal does not need to perform detection on the second transmission resource. In other embodiments, the content transmitted on the second transmission resource includes transmission of DCI. In this case, if the first indication information is not detected on the first transmission resource, the terminal does not need to perform detection on the second transmission resource; if the first indication information is detected on the first transmission resource, the terminal detects DCI on the second transmission resource.

[0457] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and these correspond to the transmission content indication information. The correspondence may include a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0458] For transmission parameter indication information (fifth type):

[0459] In some embodiments, the first configuration information is used at least to configure transmission parameter indication information, which indicates the transmission parameters corresponding to the transmission content of the second transmission resource. Optionally, the transmission parameter indication information includes DCI-related transmission parameter indication information or downlink data-related transmission parameter indication information. The DCI-related transmission parameter indication information or downlink data-related transmission parameter indication information can also be considered as subtype indication information of transmission parameter indication information, or as candidate information for transmission parameter indication information.

[0460] In some embodiments, the transmission parameter indication information is used to indicate the transmission parameters corresponding to the DCI transmitted on the second transmission resource; or, the transmission parameter indication information is used to indicate the transmission parameters corresponding to the downlink data transmitted on the second transmission resource; or, the transmission parameter indication information is used to indicate the transmission parameters corresponding to both the DCI and the downlink data transmitted on the second transmission resource. The DCI is carried via the PDCCH, and the downlink data is carried via the PDSCH.

[0461] In some embodiments, the first configuration information is used to configure the first transmission resource indication information and / or sequence indication information, and has a corresponding relationship with the transmission parameter indication information. The corresponding relationship includes a one-to-one correspondence; or a one-to-many correspondence; or a many-to-one correspondence; or a many-to-many correspondence.

[0462] The following section will introduce DCI, which refers to the content transmitted on the second transmission resource.

[0463] Optionally, taking the transmission content on the second transmission resource as DCI as an example, the transmission parameter indication information includes DCI-related transmission parameter indication information. The DCI-related transmission parameter indication information includes at least one of the following: format indication information corresponding to the DCI; bit count indication information corresponding to the DCI; aggregation level indication information corresponding to the DCI; CCE quantity indication information corresponding to the DCI; resource quantity indication information corresponding to the DCI; first identifier indication information; DMRS indication information; DMRS sequence initialization indication information; spatial filter indication information associated with the DCI; and encoding indication information.

[0464] 1) Format indication information corresponding to DCI

[0465] In some embodiments, the DCI-related transmission parameter indication information includes the format indication information corresponding to the DCI, which is used to determine the DCI format transmitted on the second transmission resource.

[0466] In some embodiments, the DCI transmitted on the second transmission resource includes at least one DCI format. If the first indication information transmitted on the first transmission resource indicates that DCI is transmitted on the second transmission resource, the terminal device performs DCI detection on the second transmission resource based on the configured DCI format.

[0467] In some embodiments, the network device sends first configuration information to the terminal device, wherein the first configuration information configures a correspondence between first transmission resource indication information and / or sequence indication information and the format indication information corresponding to the DCI. The correspondence includes a one-to-one correspondence; or a one-to-many correspondence; or a many-to-one correspondence; or a many-to-many correspondence.

[0468] Optionally, the association between the first transmission resource indication information and the format indication information corresponding to the DCI is configured in the first configuration information; that is, the first transmission resource is associated with the DCI format. Optionally, the first transmission resource is determined based on the first transmission resource indication information, and the first transmission resource is used to transmit the first indication information. For example, the DCI format is a first DCI format. If the first indication information is detected on the first transmission resource, and the first indication information indicates that DCI is transmitted on the second transmission resource, the terminal device determines the associated first DCI format based on the first transmission resource, and detects DCI on the second transmission resource based on the first DCI format.

[0469] Optionally, the association between sequence indication information and format indication information corresponding to DCI is configured in the first configuration information; that is, the sequence is configured to be associated with the DCI format. Optionally, the sequence is determined based on the sequence indication information. For example, the sequence is determined to be a first sequence based on the sequence indication information. When the terminal device detects the first sequence on the first transmission resource, the first sequence carries first indication information, which indicates that DCI is transmitted on the second transmission resource. The terminal device determines the corresponding first DCI format based on the first sequence, and detects DCI on the second transmission resource based on the first DCI format.

[0470] Optionally, the first configuration information configures the association between the first transmission resource indication information, the sequence indication information, and the format indication information corresponding to the DCI; that is, it configures the first transmission resource, the sequence, and the DCI format to be associated. Alternatively, the first configuration information configures the first transmission resource indication information and the sequence indication information, and associates them with the format indication information corresponding to the DCI. Optionally, the first transmission resource is determined based on the first transmission resource indication information, and the sequence is determined based on the sequence indication information.

[0471] For example, a sequence is determined as the first sequence based on sequence indication information. M1 first transmission resources are associated with N1 first sequences, N2 first sequences are associated with P1 DCI formats, and M2 first transmission resources are associated with P2 DCI formats. Wherein, M1, M2, N1, N2, P1, and P2 are integers greater than or equal to 1.

[0472] For example, M1=1, N1=1, N2=1, P1=1, meaning a first transmission resource is associated with a first sequence, and a first sequence is associated with a DCI format. The terminal device detects a first sequence carrying first indication information on the first transmission resource, determines the corresponding first DCI format based on the first transmission resource or the first sequence, and then detects the DCI on the second transmission resource based on the first DCI format.

[0473] For example, M1=1, N1=2, N2=1, P1=1, meaning one first transmission resource is associated with two first sequences, and one first sequence is associated with one DCI format. If the terminal device detects a first first sequence carrying first indication information on the first transmission resource, it determines the corresponding first DCI format based on the first first sequence. The terminal device then detects the DCI on the second transmission resource based on the first DCI format. If the terminal device detects a second first sequence carrying first indication information on the first transmission resource, it determines the corresponding second DCI format based on the second first sequence. The terminal device then detects the DCI on the second transmission resource based on the second DCI format.

[0474] For example, M1=1, N1=1, N2=1, P1=2, meaning one first transmission resource is associated with one first sequence, and one first sequence is associated with two DCI formats, denoted as the first DCI format and the second DCI format. If the terminal device detects a first sequence carrying first indication information on the first transmission resource, it determines the corresponding first DCI format and second DCI format based on the first sequence. The terminal device then detects DCI on the second transmission resource based on the first DCI format and the second DCI format.

[0475] 2) Bit count indication information corresponding to DCI

[0476] In some embodiments, the transmission parameter indication information related to the DCI includes the number of bits corresponding to the DCI, which is used to determine the number of bits contained in the DCI transmitted on the second transmission resource. The number of bits contained in the DCI refers to the number of information bits contained in the DCI, or it can be considered as the total number of effective bits contained in the DCI, or the total number of bits contained in the DCI.

[0477] Optionally, the DCI includes multiple information fields, or in other words, multiple fields. Each information field can be used to carry different types of control information. The terminal device detects the DCI based on the number of bits included in the DCI. If the number of bits included in the DCI is different, the terminal device needs to perform DCI detection separately for each type of field.

[0478] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and these configurations correspond to the bit count indication information corresponding to the DCI. The correspondence may include a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0479] It should be noted that the relationship between configuring the first transmission resource indication information and / or sequence indication information and the number of bits corresponding to the DCI is implemented in a similar way to "1) for the format indication information corresponding to the DCI" above, and will not be repeated here.

[0480] 3) Aggregation level indication information corresponding to DCI

[0481] In some embodiments, the DCI-related transmission parameter indication information includes the aggregation level indication information corresponding to the DCI, which is used to determine the aggregation level corresponding to the DCI transmitted on the second transmission resource.

[0482] The transmission resources of the downlink control channel include one or more CCEs. The number of CCEs is the aggregation level. Different numbers of CCEs correspond to different aggregation levels. Optionally, the aggregation level can be one of {1, 2, 4, 8, 16}.

[0483] Optionally, the DCI transmitted on the second transmission resource includes at least one aggregation level. If the first indication information transmitted on the first transmission resource indicates that the DCI is transmitted on the second transmission resource, the terminal device performs DCI detection on the second transmission resource based on the aggregation level corresponding to the configured DCI.

[0484] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and has a corresponding relationship with the aggregation level indication information corresponding to DCI. The corresponding relationship includes a one-to-one correspondence; or a one-to-many correspondence; or a many-to-one correspondence; or a many-to-many correspondence.

[0485] Optionally, the first configuration information can be configured to associate the first transmission resource indication information with the aggregation level indication information corresponding to the DCI; that is, the first transmission resource can be associated with the aggregation level corresponding to the DCI. For example, when the terminal device detects the first indication information on the first transmission resource, and the first indication information indicates that the DCI is transmitted on the second transmission resource, the terminal device determines the corresponding aggregation level based on the first transmission resource, and then the terminal device detects the DCI on the second transmission resource.

[0486] Optionally, the first configuration information configures the association between sequence indication information and aggregation level indication information corresponding to the DCI; that is, it configures the sequence to be associated with the aggregation level corresponding to the DCI. For example, a sequence is determined to be a first sequence based on the sequence indication information. When the terminal device detects the first sequence on the first transmission resource, the first sequence carries first indication information, which indicates that the DCI is transmitted on the second transmission resource. The terminal device determines the corresponding aggregation level based on the first sequence, and then detects the DCI on the second transmission resource.

[0487] It should be noted that the relationship between the configuration of the first transmission resource indication information, the sequence indication information, and the aggregation level indication information corresponding to the DCI is implemented in a similar way to "1) for the format indication information corresponding to the DCI" above, and will not be repeated here.

[0488] 4) CCE quantity indication information corresponding to DCI

[0489] In some embodiments, the transmission parameter indication information related to DCI includes the number of CCEs corresponding to DCI, which is used to determine the number of CCEs corresponding to DCI transmitted on the second transmission resource.

[0490] The transmission resources of the downlink control channel include one or more Control Cell Equipment (CCEs). Optionally, a CCE is a resource unit used by the downlink control channel to transmit downlink control information. Optionally, the transmission reliability varies depending on the number of CCEs occupied by the downlink control channel; for example, the more CCEs the downlink control channel occupies, the higher its transmission reliability. Occupying more CCEs can provide more redundancy and fault tolerance mechanisms, thereby enhancing the reliability of the downlink control channel and reducing the probability of transmission errors.

[0515] 9) Spatial filter indication information associated with DCI

[0516] In some embodiments, the DCI-related transmission parameter indication information includes DCI-associated spatial filter indication information, which is used to determine the DCI-associated spatial filter transmitted on the second transmission resource. Optionally, the spatial filter indication information includes Transmission Configuration Indicator (TCI) status information or Channel State Information Reference Signal Resource Indicator (CRI) information.

Optionally, the spatial filter includes a spatial transmit filter and / or a spatial receive filter, and the spatial transmit and receive filters have a corresponding relationship. That is, for a given spatial transmit filter, there can be a corresponding spatial receive filter. When the network device uses the spatial transmit filter for DCI transmission, the terminal device uses the corresponding spatial receive filter for reception. The spatial transmit filter can also be called a transmit beam, and the spatial receive filter can also be called a receive beam.

[0530] 1) Modulation mode indication information for downlink data

[0531] In some embodiments, the downlink data-related transmission parameter indication information includes modulation scheme indication information corresponding to the downlink data. The modulation scheme indication information is used to determine the modulation scheme corresponding to the downlink data transmitted on the second transmission resource. The modulation scheme includes, but is not limited to, at least one of BPSK, QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, 4096QAM, or other modulation schemes.

[0532] In some embodiments, the downlink data transmitted on the second transmission resource includes at least one modulation scheme. If the first indication information transmitted on the first transmission resource indicates that downlink data is transmitted on the second transmission resource, the terminal device performs downlink data detection on the second transmission resource based on the modulation scheme corresponding to the configured downlink data.

[0533] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and these configurations correspond to the modulation scheme indication information corresponding to the downlink data. The correspondence may include a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0534] Optionally, the association between the first transmission resource indication information and the modulation scheme indication information corresponding to the downlink data is configured in the first configuration information; that is, the first transmission resource is associated with the modulation scheme corresponding to the downlink data. Optionally, the first transmission resource is determined based on the first transmission resource indication information, and the modulation scheme corresponding to the downlink data is determined based on the modulation scheme indication information corresponding to the downlink data. For example, the terminal device detects the first indication information on the first transmission resource, and the first indication information indicates that downlink data is transmitted on the second transmission resource. The terminal device determines the corresponding modulation scheme based on the first transmission resource, for example, the modulation scheme is QPSK, and the terminal device detects downlink data on the second transmission resource based on the QPSK modulation scheme.

[0535] Optionally, the first configuration information configures the association between sequence indication information and modulation scheme indication information corresponding to downlink data; that is, it configures the sequence to be associated with the modulation scheme corresponding to downlink data. Optionally, the sequence is determined based on the sequence indication information. The modulation scheme corresponding to the downlink data is determined based on the modulation scheme indication information corresponding to the downlink data. For example, the sequence is determined to be a first sequence based on the sequence indication information. When the terminal device detects the first sequence on the first transmission resource, the first sequence carries first indication information, which indicates that downlink data is transmitted on the second transmission resource. The terminal device determines the corresponding modulation scheme based on the first sequence, for example, the modulation scheme is 16QAM. The terminal device detects downlink data on the second transmission resource based on the 16QAM modulation scheme.

[0536] Optionally, the first configuration information configures the association between the first transmission resource indication information, the sequence indication information, and the modulation scheme indication information corresponding to the downlink data; that is, it configures the first transmission resource, the sequence, and the modulation scheme corresponding to the downlink data to be associated. Alternatively, the first configuration information configures the first transmission resource indication information and the sequence indication information, and associates them with the modulation scheme indication information corresponding to the downlink data. Optionally, the first transmission resource is determined based on the first transmission resource indication information, and the sequence is determined based on the sequence indication information.

[0537] For example, a sequence is determined as the first sequence based on sequence indication information. M1 first transmission resources are associated with N1 first sequences, N2 first sequences are associated with P1 DCI formats, and M2 first transmission resources are associated with P2 DCI formats. Wherein, M1, M2, N1, N2, P1, and P2 are integers greater than or equal to 1.

[0538] For example, M1=1, N1=1, N2=1, P1=1, meaning that a first transmission resource is associated with a first sequence, and a first sequence is associated with a modulation scheme. The terminal device detects the first sequence carrying the first indication information on the first transmission resource, determines the corresponding modulation scheme based on the first transmission resource or the first sequence, and detects DCI on the second transmission resource based on the modulation scheme corresponding to the downlink data.

[0539] For example, M1=1, N1=2, N2=1, P1=1, meaning one first transmission resource is associated with two first sequences, and one first sequence is associated with one modulation scheme. If the terminal device detects a first first sequence carrying first indication information on the first transmission resource, it determines the corresponding first DCI format based on the first first sequence, and the terminal device detects DCI on the second transmission resource based on the first DCI format. If the terminal device detects a second first sequence carrying first indication information on the first transmission resource, it determines the corresponding second DCI format based on the second first sequence, and the terminal device detects DCI on the second transmission resource based on the second DCI format.

[0540] For example, M1=1, N1=1, N2=1, P1=2, meaning one first transmission resource is associated with one first sequence, and one first sequence is associated with two modulation schemes, denoted as the first modulation scheme and the second modulation scheme. If the terminal device detects a first sequence carrying first indication information on the first transmission resource, it determines the corresponding first modulation scheme and the second modulation scheme based on the first sequence. The terminal device then detects DCI on the second transmission resource based on the first modulation scheme and the second modulation scheme.

[0541] 2) MCS level indication information corresponding to downlink data

[0542] In some embodiments, the downlink data-related transmission parameter indication information includes MCS level indication information corresponding to the downlink data. The MCS level indication information is used to determine the MCS level corresponding to the downlink data transmitted on the second transmission resource. The MCS level can also be referred to as the MCS index. The MCS index is a specific representation of the MCS level. Each MCS level corresponds to a specific set of modulation schemes and coding rates, used to select appropriate transmission parameters based on channel quality.

[0543] In some embodiments, downlink data transmitted on the second transmission resource corresponds to at least one MCS level. If the first indication information transmitted on the first transmission resource indicates that downlink data is transmitted on the second transmission resource, the terminal device performs downlink data detection on the second transmission resource based on the configured MCS level corresponding to the downlink data.

[0544] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and these first configuration information correspond to the MCS level indication information corresponding to the downlink data. The correspondence may include a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0545] The following explanation uses the association between the sequence indication information configured in the first configuration information and the MCS level indication information corresponding to the downlink data as an example. The sequence indication information and the MCS level indication information corresponding to the downlink data are associated; this can also be understood as the first transmission resource being associated with the MCS level. For example, a sequence is determined as the first sequence based on the sequence indication information. When the terminal device detects the first sequence on the first transmission resource, this first sequence carries first indication information, which indicates that downlink data will be transmitted on the second transmission resource. The terminal device determines the corresponding MCS level based on this first sequence; for example, if the MCS level is 12, the terminal device detects downlink data on the second transmission resource based on MCS level 12.

[0546] It should be noted that the relationship between configuring the first transmission resource indication information and / or sequence indication information and the MCS level indication information is implemented in a similar way to "1) Modulation mode indication information corresponding to downlink data" above, and will not be repeated here.

[0547] 3) MCS table indication information corresponding to downlink data

[0548] In some embodiments, the downlink data-related transmission parameter indication information includes MCS table indication information corresponding to the downlink data.

The MCS table includes an MCS table supporting a maximum of 64QAM, an MCS table supporting a maximum of 256QAM, an MCS table supporting a maximum of 1024QAM, an MCS table supporting a maximum of 4096QAM, or an MCS table supporting low spectral efficiency.

[0549] Among them, the highest modulation order in the MCS table that supports up to 64QAM is 6, meaning each symbol carries 6 bits of information (in 2^64QAM). 6 =64 different symbol representations). The highest modulation order in the MCS table that supports a maximum of 256QAM is 8, meaning each symbol carries 8 bits of information (in 2^35QAM). 8 =256 different symbol representations). The highest modulation order in the MCS table that supports up to 1024QAM is 10, meaning each symbol carries 10 bits of information (in 2... 10=1024 different symbol representations). The highest modulation order in the MCS table that supports a maximum of 4096QAM is 12, and each symbol carries 12 bits of information (in 2^32). 12 =4096 different symbol representations). The MCS table supporting low spectral efficiency includes MCS schemes with lower modulation order and lower coding rate. The modulation order refers to the order of the modulation scheme, used to indicate the number of bits included in the data signal.

[0550] In some embodiments, downlink data transmitted on the second transmission resource corresponds to at least one MCS table. If the first indication information transmitted on the first transmission resource indicates that downlink data is transmitted on the second transmission resource, the terminal device performs downlink data detection on the second transmission resource based on the configured MCS table corresponding to the downlink data.

[0551] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and these first configuration information correspond to the MCS table indication information corresponding to the downlink data. The correspondence may include a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0552] It should be noted that the relationship between the configuration of the first transmission resource indication information and / or sequence indication information and the MCS table indication information is implemented in a similar way to "1) the modulation scheme indication information corresponding to downlink data" above, and will not be repeated here.

The correspondence may include a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0557] It should be noted that the relationship between configuring the first transmission resource indication information and / or sequence indication information and the encoding indication information corresponding to the downlink data is implemented in a similar way to "1) the modulation scheme indication information corresponding to the downlink data" above, and will not be repeated here.

[0559] In some embodiments, the transmission parameter indication information related to downlink data includes the coding rate indication information corresponding to the downlink data, which is used to determine the coding rate corresponding to the downlink data transmitted on the second transmission resource.

[0560] Encoding rate refers to the ratio of the original data volume to the encoded data volume in data transmission. In other words, the encoding rate is the ratio of the effective data bits after encoding to the total number of transmitted bits, reflecting the effectiveness of the encoded information relative to the total transmitted information.

[0561] In some embodiments, the first configuration information sent by the network device includes the coding rate. If the first indication information transmitted on the first transmission resource indicates that downlink data is transmitted on the second transmission resource, the terminal device performs downlink data detection on the second transmission resource based on the coding rate corresponding to the configured downlink data.

[0565] In some embodiments, the transmission parameter indication information related to downlink data includes TBS indication information corresponding to downlink data, which is used to determine the TBS corresponding to the downlink data transmitted on the second transmission resource.

[0566] TBS is a parameter used to describe the physical layer transport block size, representing the amount of data transmitted. The size of the TBS is related to parameters such as the size of the second transport resource, modulation scheme, and coding rate.

[0567] In some embodiments, the first configuration information sent by the network device includes TBS indication information.

[0582] In some embodiments, resource block group (RBG) indication information is used to indicate the number of Physical Resource Blocks (PRBs) contained within a resource block group. A resource block (PRB) is the smallest unit used for scheduling and transmitting data; each PRB typically contains 12 consecutive subcarriers and occupies one time slot in the time domain. A resource block group (RBG) is a collection of resource blocks (PRBs) and can be considered a larger scheduling unit. For example, an RBG may contain 4, 8, or 16 PRBs.

When the second transmission resource is used to transmit downlink data, the resource block binding size indication information is used to indicate the number of PRBs that can be bound and processed. The terminal device performs downlink data detection on the second transmission resource based on the configured number of PRBs corresponding to the downlink data.

[0589] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and these correspond to resource block binding size indication information. The correspondence may include a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0590] It should be noted that the relationship between configuring the first transmission resource indication information and / or sequence indication information and the resource block binding size indication information is implemented in a similar way to "1) the modulation scheme indication information corresponding to downlink data" above, and will not be repeated here.

[0591] 11) Regarding the demodulation reference signal (DMRS) indication information

[0592] In some embodiments, the downlink data-related transmission parameter indication information includes demodulation reference signal indication information, which is used to indicate DMRS information corresponding to the downlink data transmitted on the second transmission resource. Optionally, the DMRS information includes at least one of the following: time-domain resources of the DMRS; frequency-domain resources of the DMRS; and a pattern of the DMRS.

[0593] In some embodiments, downlink data is carried via the PDSCH. To receive downlink data, the terminal device performs channel estimation based on the DMRS. Optionally, the PDSCH's DMRS supports multiple DMRS patterns. The terminal device determines the DMRS pattern, or the time-domain resources of the DMRS, or the frequency-domain resources of the DMRS based on demodulation reference signal indication information. For example, the PDSCH's DMRS supports multiple DMRS patterns, each corresponding to a specific time-domain resource and frequency-domain resource.

[0594] In some embodiments, the first configuration information sent by the network device includes demodulation reference signal indication information, and the downlink data transmitted on the second transmission resource corresponds to at least one DMRS information. If the first indication information transmitted on the first transmission resource indicates that downlink data is transmitted on the second transmission resource, the terminal device performs downlink data detection on the second transmission resource based on the DMRS information corresponding to the configured downlink data.

[0595] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and these correspond to demodulation reference signal indication information. The correspondence may include a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0596] It should be noted that the relationship between configuring the first transmission resource indication information and / or sequence indication information and the demodulation reference signal indication information is implemented in a similar way to "1) the modulation scheme indication information corresponding to downlink data" above, and will not be repeated here.

[0597] 12) Initialization indication information for the demodulation reference signal (DMRS) sequence.

[0598] In some embodiments, the downlink data-related transmission parameter indication information includes demodulation reference signal sequence initialization indication information, which is used to indicate the DMRS sequence corresponding to the downlink data transmitted on the second transmission resource.

[0599] In some embodiments, the demodulation reference signal corresponds to a DMRS sequence, which is determined based on a first initial value. The terminal device determines the initial value corresponding to the DMRS sequence based on the demodulation reference signal sequence initialization information, and thus determines the DMRS sequence. For example, the DMRS sequence is determined based on the following formula (3):

[0600] Where c(i) corresponds to a pseudo-random sequence, which can be generated based on formula (1) above, with parameter C init It can be determined based on the first parameter, the value of which is determined based on the demodulation reference signal sequence initialization information.

[0601] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and has a correspondence with demodulation reference signal sequence initialization indication information. The correspondence includes a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0602] It should be noted that the relationship between configuring the first transmission resource indication information and / or sequence indication information and the demodulation reference signal sequence initialization indication information is implemented in a similar way to "1) the modulation scheme indication information corresponding to downlink data" above, and will not be repeated here.

[0603] 13) Spatial filter indication information for downlink data association

[0604] In some embodiments, the downlink data-related transmission parameter indication information includes downlink data-associated spatial filter indication information, which is used to determine the spatial filter associated with the downlink data transmitted on the second transmission resource. Optionally, the spatial filter indication information includes Transmission Configuration Indication (TCI) status information or Channel State Information Reference Signal Resource Indication (CRI) information.

[0605] In some embodiments, network devices and terminal devices use beams for data transmission and reception; these beams are also referred to as spatial filters. Optionally, the spatial filter includes a spatial transmit filter and / or a spatial receive filter, and these filters have a corresponding relationship. That is, for one spatial transmit filter, there can be a corresponding spatial receive filter. When the network device uses the spatial transmit filter to transmit downlink data, the terminal device uses the corresponding spatial receive filter to receive data. The spatial transmit filter can also be called a transmit beam, and the spatial receive filter can also be called a receive beam.

[0606] In some embodiments, the first configuration information sent by the network device includes spatial filter indication information, and the terminal device determines the corresponding spatial receiving filter based on the spatial filter indication information in order to receive and detect downlink data.

[0607] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and has a corresponding relationship with the spatial filter indication information associated with downlink data. The corresponding relationship includes a one-to-one correspondence; or a one-to-many correspondence; or a many-to-one correspondence; or a many-to-many correspondence.

[0608] It should be noted that the relationship between the configuration of the first transmission resource indication information and / or sequence indication information and the spatial filter indication information associated with the downlink data is implemented in a similar way to "1) the modulation scheme indication information corresponding to the downlink data" above, and will not be repeated here.

[0609] Regarding resource location indication information (sixth type):

[0610] In some embodiments, the first configuration information is used to configure resource location indication information, which is used to indicate the resource location of the transmission resource corresponding to the transmission content on the second transmission resource.

[0611] In some embodiments, the resource location indication information includes at least one of resource start location indication information, resource end location indication information, and resource size indication information. The resource start location indication information indicates the start position of the transmission resource corresponding to the transmission content on the second transmission resource. The resource end location indication information indicates the end position of the transmission resource corresponding to the transmission content on the second transmission resource. The resource size indication information indicates the resource size occupied by the transmission resource corresponding to the transmission content on the second transmission resource. The indication information included in the above-mentioned resource location indication information can be considered as subtype indication information of resource location indication information, or it can be considered as candidate information of resource location indication information.

[0612] In some embodiments, the resource location of the transmission resource corresponding to the transmission content within the second transmission resource includes, but is not limited to, at least one of a resource start position, a resource end position, and a resource size. The resource start position includes at least one of a time-domain start position, a frequency-domain start position, and a logical resource unit start position. The resource end position includes at least one of a time-domain end position, a frequency-domain end position, and a logical resource unit end position. The resource size includes at least one of the number of time-domain units, the number of frequency-domain units, and the number of logical units.

[0613] In some embodiments, the network device sends first configuration information to the terminal device, which configures first transmission resource indication information and / or sequence indication information, and these correspond to resource location indication information. The correspondence may include a one-to-one correspondence; a one-to-many correspondence; a many-to-one correspondence; or a many-to-many correspondence.

[0614] The following explanation uses the example of resource location indication information used to indicate the frequency domain starting position of the transmission resource corresponding to the transmission content on the second transmission resource.

[0615] Optionally, the association between the first transmission resource indication information and the resource location indication information is configured in the first configuration information, that is, the first transmission resource is associated with the resource location. Optionally, the first transmission resource is determined based on the first transmission resource indication information. For example, the resource location is determined as the first frequency domain start position based on the resource location indication information. If the terminal device detects the first indication information on the first transmission resource, and the first indication information indicates that DCI or downlink data is transmitted on the second transmission resource, the terminal device determines the associated first frequency domain start position based on the first transmission resource, that is, it starts detecting DCI or downlink data on the second transmission resource from the first frequency domain start position.

[0616] Optionally, the association between sequence indication information and resource location indication information is configured in the first configuration information, that is, the sequence is associated with the resource location. For example, the sequence is determined as a first sequence based on the sequence indication information, and the resource location is determined as a first frequency domain start position based on the resource location indication information. If the terminal device detects the first sequence on the first transmission resource, the first sequence carries first indication information, and the first indication information indicates that DCI or downlink data is transmitted on the second transmission resource. The terminal device determines the associated first frequency domain start position based on the first sequence, that is, it starts detecting DCI or downlink data on the second transmission resource from the first frequency domain start position.

[0617] Optionally, the first configuration information configures the association between the first transmission resource and sequence indication information and the resource location indication information; that is, it configures the first transmission resource and sequence to be associated with the resource location. For example, a sequence is determined as a first sequence based on the sequence indication information, and a resource location is determined as a first frequency domain start position based on the resource location indication information. One first transmission resource is associated with one first sequence, and one first sequence is associated with a first frequency domain start position. When the terminal device detects the first sequence carrying the first indication information on the first transmission resource, it determines the corresponding first frequency domain start position based on the first transmission resource or the first sequence; that is, it starts detecting DCI or downlink data on the second transmission resource from the first frequency domain start position.

[0618] The first configuration information is used to configure the association between at least two types of indication information.

[0619] In some embodiments, the network device sends first configuration information to the terminal device. The first configuration information is used to configure the association relationship between at least two types of indication information. Here, the association relationship can also be referred to as the correspondence relationship.

[0620] In some embodiments, the first configuration information is used to configure the association between two types of indication information. The first configuration information is used to configure the association between any two types of indication information among the first transmission resource indication information, sequence indication information, repeated transmission indication information, transmission content indication information, transmission parameter indication information, and resource location indication information.

[0621] For example, the first configuration information is used to configure the association between the first transmission resource indication information and the sequence indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information and the repeat transmission indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information and the transmission content indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information and the transmission parameter indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information and the resource location indication information; for example, the first configuration information is used to configure the association between the sequence indication information and the repeat transmission indication information; for example, the first configuration information is used to configure the association between the sequence indication information and the transmission content indication information; for example, the first configuration information is used to configure the association between the sequence indication information and the transmission parameter indication information; for example, the first configuration information is used to configure the association between the sequence indication information and the resource location indication information; for example, the first configuration information is used to configure the association between the repeat transmission indication information and the transmission content indication information... This application does not limit this.

[0622] In some embodiments, the first configuration information is used to configure the association between three types of indication information. The first configuration information is used to configure the association between any three types of indication information among the first transmission resource indication information, sequence indication information, repeated transmission indication information, transmission content indication information, transmission parameter indication information, and resource location indication information.

[0623] For example, the first configuration information is used to configure the association between the first transmission resource indication information and the sequence indication information and the repeated transmission indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information and the sequence indication information and the transmission content indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information and the sequence indication information and the transmission parameter indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information and the sequence indication information and the resource location indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information and the repeated transmission indication information and the transmission content indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information and the repeated transmission indication information and the transmission parameter indication information... This application does not limit this.

[0624] In some embodiments, the first configuration information is used to configure the association between four types of indication information. The first configuration information is used to configure the association between any four types of indication information, including first transmission resource indication information, sequence indication information, repeated transmission indication information, transmission content indication information, transmission parameter indication information, and resource location indication information.

[0625] For example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, repeated transmission indication information, and transmission content indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, repeated transmission indication information, and transmission parameter indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, repeated transmission indication information, and resource location indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, transmission content indication information, and transmission parameter indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, transmission content indication information, and resource location indication information... This application does not limit this.

[0626] In some embodiments, the first configuration information is used to configure the association between five types of indication information. The first configuration information is used to configure the association between any five types of indication information among the first transmission resource indication information, sequence indication information, repeated transmission indication information, transmission content indication information, transmission parameter indication information, and resource location indication information.

[0627] For example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, repeated transmission indication information, transmission content indication information, and transmission parameter indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, repeated transmission indication information, transmission content indication information, and resource location indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, repeated transmission indication information, transmission parameter indication information, and resource location indication information; for example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, transmission content indication information, transmission parameter indication information, and resource location indication information... This application does not limit this.

[0628] In some embodiments, the first configuration information is used to configure the association between six types of indication information, namely, the first transmission resource indication information, the sequence indication information, the repeated transmission indication information, the transmission content indication information, the transmission parameter indication information, and the resource location indication information.

[0629] For example, the first configuration information is used to configure the association between the first transmission resource indication information, sequence indication information, repeated transmission indication information, transmission content indication information, transmission parameter indication information and resource location indication information.

[0630] It should be noted that each type of indication information above also includes sub-type indication information. For example, the sub-type indication information of the first transmission resource indication information includes at least one of the time domain resource information, the frequency domain resource information, and the index information of the first transmission resource; as another example, the sub-type indication information of the sequence indication information includes at least one of the initial value indication information corresponding to the sequence, the cyclic shift value indication information corresponding to the sequence, the group number indication information corresponding to the sequence, the base sequence number indication information corresponding to the sequence, the sequence length indication information corresponding to the sequence, and the sequence index indication information corresponding to the sequence.

[0631] The aforementioned first configuration information is used to configure the association between at least two types of indication information, and also includes configuring the association between at least one type of indication information and subtype indication information included in another type of indication information (examples are illustrated in the "Further Introduction to Indication Information in the First Configuration Information" section above), for example, there is an association between the first transmission resource indication information and the format indication information corresponding to DCI. The aforementioned first configuration information is used to configure the association between at least two types of indication information, and also includes configuring the association between at least one subtype of indication information and another subtype of indication information. This application does not limit this aspect.

[0632] The following describes different scenarios of the association between at least two types of indication information in the first configuration information. It should be noted that the following examples are provided but cannot exhaust all possible combinations; the examples are for illustrative purposes only.

[0633] Scenario 1: The first configuration information is used to configure the first association between the first transmission resource indication information and the sequence indication information.

[0634] In some embodiments, the network device sends first configuration information to the terminal device. This first configuration information is used to configure a first association between first transmission resource indication information and sequence indication information. Alternatively, it can be understood that the first configuration information is used to configure a first association between a first transmission resource and a sequence. Specifically, the first transmission resource indication information indicates the resource information of the first transmission resource. The sequence indication information determines the sequence transmitted on the first transmission resource, and the sequence carries the first indication information. The first indication information also indicates the transmission information of a second transmission resource.

[0635] In some embodiments, the network device configures a first association between at least one first transmission resource indication information and at least one sequence indication information. Optionally, the network device configures each of the at least one first transmission resource indication information to have a corresponding sequence indication information.

[0636] For example, the network device configures an association between two first transmission resource indication information and sequence indication information, namely, first transmission resource indication information A and first transmission resource indication information B. For instance, it configures an association between first transmission resource indication information A and first sequence indication information, meaning that the first transmission resource indicated by first transmission resource indication information A is associated with at least one sequence. Similarly, it configures an association between first transmission resource indication information B and second sequence indication information, meaning that the first transmission resource indicated by first transmission resource indication information B is associated with at least one sequence.

[0637] In some embodiments, the resource information of the first transmission resource includes, but is not limited to, at least one of the following: time-domain resource information, frequency-domain resource information, and index information of the first transmission resource. The sequence indication information includes, but is not limited to, at least one of the following: initial value indication information corresponding to the sequence; cyclic shift value indication information corresponding to the sequence; group number indication information corresponding to the sequence; base sequence number indication information corresponding to the sequence; sequence length indication information corresponding to the sequence; and sequence index indication information corresponding to the sequence.

[0638] In some embodiments, the first association relationship may be the association relationship between the subtype indication information of the first transmission indication information and the subtype indication information of the sequence indication information. Alternatively, it can be understood that the first configuration information is used to configure the first association relationship between the subtype indication information of the first transmission indication information and the subtype indication information of the sequence indication information. For example, the first association relationship may be the association relationship between the time-domain resource information of the first transmission resource and the initial value indication information corresponding to the sequence; or, for example, the first association relationship may be the association relationship between the frequency-domain resource information of the first transmission resource and the cyclic shift value indication information corresponding to the sequence; or, for example, the first association relationship may be the association relationship between the index information of the first transmission resource and the group number indication information corresponding to the sequence… This application does not limit this to any particular type.

[0639] It should be noted that the sub-type indication information corresponding to each type of indication information can also be regarded as the candidate information (candidate configuration information) corresponding to each type of indication information. The same applies below, and will not be repeated here.

[0640] For example, referring to Figure 17, the network device configures two associated first transmission resources and one associated second transmission resource, that is, one second transmission resource is associated with two first transmission resources. The two first transmission resources are each associated with two OFDM symbols, symbol 0 and symbol 1 respectively. The first configuration information sent by the network device is used to configure a first association relationship between the first transmission resources and the sequence carrying the first indication information; that is, the first configuration information is used to configure the first transmission resources and the sequence carrying the first indication information to correspond (or be associated). Optionally, the first indication information is used to indicate the transmission content on the second transmission resource, or to indicate the transmission parameters corresponding to the transmission content on the second transmission resource, or to indicate the resource position of the transmission resource corresponding to the transmission content on the second transmission resource.

[0641] As shown in Figure 17(a), the first configuration information sent by the network device is used to configure a one-to-one correspondence between the first transmission resource and the sequence, that is, one first transmission resource is associated with one sequence. For example, the first transmission resource of symbol 0 corresponds to sequence 0, and the first transmission resource of symbol 1 corresponds to sequence 1. Relative to the terminal device, sequence 0 is detected on the first transmission resource of symbol 0, and sequence 1 is detected on the first transmission resource of symbol 1. The second transmission resource is then detected based on the first indication information carried by the detected sequence.

[0642] As shown in Figure 17(b), the first configuration information sent by the network device is used to configure a one-to-many correspondence between the first transmission resource and the sequence, that is, one first transmission resource is associated with multiple sequences. For example, the first transmission resource of symbol 0 corresponds to sequence 0 and sequence 1, and the first transmission resource of symbol 1 corresponds to sequence 2 and sequence 3. Relative to the terminal device, sequence 0 or sequence 1 is detected on the first transmission resource of symbol 0, and sequence 2 or sequence 3 is detected on the first transmission resource of symbol 1. The second transmission resource is then detected based on the first indication information carried by the detected sequence.

[0643] Scenario 2: The first configuration information is used to configure the second association relationship between the first transmission resource indication information, sequence indication information, and transmission content indication information.

[0644] In some embodiments, the network device sends first configuration information to the terminal device. The first configuration information is used to configure a second association between first transmission resource indication information, sequence indication information, and transmission content indication information. Alternatively, the first configuration information can be understood as configuring a second association between first transmission resources, the sequence carrying the first indication information, and the transmission content.

[0645] The first transmission resource indication information is used to indicate the resource information of the first transmission resource. The sequence indication information is used to determine the sequence transmitted on the first transmission resource, the sequence is used to carry the first indication information, and the first indication information is used to indicate the transmission information of the second transmission resource. The transmission content indication information is used to indicate the transmission content of the second transmission resource.

[0646] In some embodiments, the resource information of the first transmission resource includes, but is not limited to, at least one of the following: time-domain resource information, frequency-domain resource information, and index information of the first transmission resource. The sequence indication information includes, but is not limited to, at least one of the following: initial value indication information corresponding to the sequence; cyclic shift value indication information corresponding to the sequence; group number indication information corresponding to the sequence; base sequence number indication information corresponding to the sequence; sequence length indication information corresponding to the sequence; and sequence index indication information corresponding to the sequence.

[0647] In some embodiments, the second association relationship may be the association relationship between the subtype indication information of the first transmission indication information, the subtype indication information of the sequence indication information, and the transmission content indication information. Alternatively, it can be understood that the first configuration information is used to configure the second association relationship between the subtype indication information of the first transmission indication information, the subtype indication information of the sequence indication information, and the transmission content indication information. For example, the second association relationship may be the association relationship between the time-domain resource information of the first transmission resource, the initial value indication information corresponding to the sequence, and the transmission content indication information; or, for example, the second association relationship may be the association relationship between the frequency-domain resource information of the first transmission resource, the cyclic shift value indication information corresponding to the sequence, and the transmission content indication information; or, for example, the second association relationship may be the association relationship between the index information of the first transmission resource, the group number indication information corresponding to the sequence, and the transmission content indication information… This application does not limit this to any particular type.

[0648] For example, referring to Figure 18, the network device configures two associated first transmission resources and one associated second transmission resource, that is, one second transmission resource is associated with two first transmission resources. The two first transmission resources are each associated with two OFDM symbols, symbol 0 and symbol 1 respectively. The first configuration information sent by the network device is used to configure a second association relationship between the first transmission resources, the first indication information, and the transmission content; that is, the first configuration information is used to configure the correspondence (or association) between the first transmission resources, the sequence carrying the first indication information, and the transmission content.

[0649] As shown in Figure 18(a), the first configuration information sent by the network device is used to configure a one-to-many correspondence between the first transmission resource and the sequence, that is, one first transmission resource is associated with multiple sequences. For example, the first transmission resource of symbol 0 corresponds to sequence 0 and sequence 1. Sequence 0 is used to indicate that the transmission content on the second transmission resource is DCI transmission, and sequence 1 is used to indicate that the transmission content on the second transmission resource is downlink data transmission; the first transmission resource of symbol 1 corresponds to sequence 0 and sequence 1. Sequence 0 is used to indicate that the transmission content on the second transmission resource is DCI and downlink data transmission, and sequence 1 is used to indicate that the transmission content on the second transmission resource is no transmission. Relative to the terminal device, sequence 0 or sequence 1 is detected on the first transmission resource of symbol 0, and sequence 0 or sequence 1 is detected on the first transmission resource of symbol 1. The transmission content on the second transmission resource is determined based on the first indication information carried by the detected sequence.

[0650] As shown in Figure 18(b), the first configuration information sent by the network device is used to configure a one-to-many correspondence between the first transmission resource and the sequence, that is, one first transmission resource is associated with multiple sequences. For example, the first transmission resource of symbol 0 corresponds to sequence 0 and sequence 1. Sequence 0 is used to indicate that the transmission content on the second transmission resource is DCI transmission, and sequence 1 is used to indicate that the transmission content on the second transmission resource is downlink data transmission. The first transmission resource of symbol 1 corresponds to sequence 2 and sequence 3. Sequence 2 is used to indicate that the transmission content on the second transmission resource is DCI and downlink data transmission, and sequence 3 is used to indicate that the transmission content on the second transmission resource is no transmission. Relative to the terminal device, sequence 0 or sequence 1 is detected on the first transmission resource of symbol 0, and sequence 2 or sequence 3 is detected on the first transmission resource of symbol 1. The transmission content on the second transmission resource is determined based on the first indication information carried by the detected sequence.

[0651] Scenario 3: The first configuration information is used to configure the third association between the first transmission resource indication information, sequence indication information, transmission content indication information, and transmission parameter indication information.

[0652] In some embodiments, the network device sends first configuration information to the terminal device. This first configuration information is used to configure a third association between first transmission resource indication information, sequence indication information, transmission content indication information, and transmission parameter indication information. Alternatively, the first configuration information can be understood as configuring a third association between first transmission resources, the sequence carrying the first indication information, transmission content, and transmission parameters.

[0653] The first transmission resource indication information is used to indicate the resource information of the first transmission resource. The sequence indication information is used to determine the sequence transmitted on the first transmission resource, the sequence is used to carry the first indication information, and the first indication information is used to indicate the transmission information of the second transmission resource. The transmission content indication information is used to indicate the transmission content of the second transmission resource. The transmission parameter indication information is used to indicate the transmission parameters corresponding to the transmission content of the second transmission resource. Optionally, the transmission parameter indication information includes DCI-related transmission parameter indication information, or the transmission parameter indication information includes downlink data-related transmission parameter indication information.

[0654] In some embodiments, the third association relationship may be the association relationship between the subtype indication information of the first transmission indication information, the subtype indication information of the sequence indication information, the transmission content indication information, and the subtype indication information of the transmission parameter indication information. It can also be understood that the first configuration information is used to configure the third association relationship between the subtype indication information of the first transmission indication information, the subtype indication information of the sequence indication information, the transmission content indication information, and the subtype indication information of the transmission parameter indication information. For example, the third association relationship may be the association relationship between the time-domain resource information of the first transmission resource, the initial value indication information corresponding to the sequence, the transmission content indication information, and the format indication information corresponding to the DCI; or, for example, the third association relationship may be the association relationship between the frequency-domain resource information of the first transmission resource, the cyclic shift value indication information corresponding to the sequence, the transmission content indication information, and the aggregation level indication information corresponding to the DCI; or, for example, the third association relationship may be the association relationship between the index information of the first transmission resource, the group number indication information corresponding to the sequence, the transmission content indication information, and the modulation scheme indication information corresponding to the downlink data… This application does not limit this.

[0655] For example, referring to Figure 19, the network device configures two associated first transmission resources and one associated second transmission resource, that is, one second transmission resource is associated with two first transmission resources. The two first transmission resources are each associated with two OFDM symbols, symbol 0 and symbol 1 respectively. The first configuration information sent by the network device is used to configure the third association relationship between the first transmission resources, the first indication information, the transmission content, and the transmission parameters.

[0656] As shown in Figure 19(a), the first configuration information sent by the network device is used to configure a one-to-many correspondence between the first transmission resources and sequences, that is, one first transmission resource is associated with multiple sequences. For example, the first transmission resource with symbol 0 corresponds to sequences 0 and 1. Sequences 0 and 1 on the first transmission resource with symbol 0 are used to indicate that the transmission content on the second transmission resource is DCI transmission. Sequence 0 indicates that the DCI transmitted by the second transmission resource corresponds to 2 CCEs, and sequence 1 indicates that the DCI transmitted by the second transmission resource corresponds to 4 CCEs. The first transmission resource with symbol 1 corresponds to sequences 0 and 1. Sequences 0 and 1 on the first transmission resource with symbol 0 are used to indicate that the transmission content on the second transmission resource is downlink data. Sequence 0 indicates that the modulation scheme of the downlink data transmitted by the second transmission resource is QPSK, and sequence 1 indicates that the modulation scheme of the downlink data transmitted by the second transmission resource is 16QAM. For the terminal device, if sequence 0 or sequence 1 is detected on the first transmission resource of symbol 0, it is determined that DCI is transmitted on the second transmission resource, and the number of CCEs corresponding to DCI can be determined to be 2 or 4 respectively; if sequence 0 or sequence 1 is detected on the first transmission resource of symbol 1, it is determined that downlink data is transmitted on the second transmission resource, and the modulation scheme corresponding to the downlink data can be determined to be QPSK or 16QAM respectively.
