[0058] 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.

[0059] The following section describes the relevant technologies involved in the embodiments of this application:

[0060] Physical downlink control channel detection:

[0061] Network devices send Downlink Control Information (DCI) to terminal devices. DCI is 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). DCI is also used to transmit common control information, carried via PDCCH. 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 within the search space. The maximum number of PDCCHs a terminal device can monitor in a single time slot is related to the subcarrier spacing. For example, with a 15kHz subcarrier spacing, the maximum number of PDCCHs a terminal device can monitor in a single time slot is 44. Referring to Table 1, when the subcarrier spacing parameter μ takes values ​​of 0, 1, 2, and 3, it corresponds to subcarrier spacings of 15kHz, 30kHz, 60kHz, and 120kHz, respectively.

[0062] Table 1

[0063] 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.

[0064] 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 one PRB in the frequency domain and one 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.

[0065] Table 2

[0066] Terminal device complexity optimization:

[0067] Terminal devices, often simply referred to as terminals, are designed to support extremely high peak data rates in NR Release 15 or 16 (R15 / R16). Therefore, the requirements for terminal capabilities are 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, and a maximum carrier bandwidth of 400MHz for millimeter-wave frequencies. 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, while NR R15 requires two transmit and four receive antennas for frequencies above 2500MHz. NR R15 / R16 also does not support half-duplex, requiring data processing capabilities for all uplink and downlink time slots.

[0068] 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 capabilities.

[0069] 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.

[0070] 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.

[0071] In some embodiments, a set of transmission resources configured by the network device for the terminal device includes at least two transmission resources.

[0072] Optionally, a set of transmission resources includes a first transmission resource and other transmission resources, wherein the other transmission resources are at least one transmission resource in the set of transmission resources other than the first transmission resource. The other transmission resources include: at least one second transmission resource; and / or, at least one third transmission resource. The first transmission resource is used to transmit first indication information, which indicates the transmission content on the other transmission resources; the second transmission resource is used for downlink transmission; and the third transmission resource is used for uplink transmission.

[0073] In a set of transmission resources, there may be multiple first transmission resources, second transmission resources, and third transmission resources. The following embodiments mainly illustrate this by using other transmission resources including one second transmission resource and one third transmission resource.

[0074] In this embodiment, the network device configures a first transmission resource and a second transmission resource to the terminal device, and the first and second transmission resources are associated with each other; alternatively, the network device configures a first transmission resource and a third transmission resource to the terminal device, and the first and third transmission resources are associated with each other; or alternatively, the network device configures a first transmission resource, a second transmission resource, and a third transmission resource to the terminal device, and the first, second, and third transmission resources are associated with each other. The terminal device can determine the location of the second and / or third transmission resources based on the location of the first transmission resource.

[0075] The correspondence and location relationships between transmission resources:

[0076] In some embodiments, the correspondence may also be referred to as the association relationship, and the correspondence relationship includes at least one of the following:

[0077] (1) The correspondence between the first transmission resource and the second transmission resource is one-to-one or many-to-one; where one-to-one means that one first transmission resource corresponds to one second transmission resource, and many-to-one means that multiple first transmission resources correspond to the same second transmission resource.

[0078] (2) The correspondence between the first transmission resource and the third transmission resource is one-to-one or many-to-one; where one-to-one means that one first transmission resource corresponds to one third transmission resource, and many-to-one means that multiple first transmission resources correspond to the same third transmission resource.

[0079] (3) The correspondence between the second transmission resource and the third transmission resource is one-to-one or many-to-one; where one-to-one means that one second transmission resource corresponds to one third transmission resource, and many-to-one means that multiple second transmission resources correspond to the same third transmission resource.

[0080] Figure 2 illustrates a schematic diagram of the correspondence between transmission resources provided in an exemplary embodiment of this application.

[0081] Referring to Figure 2, the first transmission resource carries first indication information, the second transmission resource is used to transmit DCI and / or downlink data, and the third transmission resource is used to transmit feedback information and / or uplink data. In Figure 2(a), the correspondence between the first and second transmission resources is one-to-one, and the correspondence between the first and third transmission resources is also one-to-one. In Figure 2(b), the correspondence between the first and second transmission resources is one-to-one, and the correspondence between the first and third transmission resources is many-to-one, meaning that two first transmission resources correspond to the same third transmission resource.

[0082] Figure 3 illustrates a schematic diagram of the positional relationship between transmission resources provided in an exemplary embodiment of this application.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] In some embodiments, the location of the third transmission resource is determined based on the location of the second transmission resource; or, there is a predefined relationship between the location of the third transmission resource and the location of the second transmission resource based on a communication protocol; or, there is a pre-configured relationship between the location of the third transmission resource and the location of the second transmission resource based on a network.

[0089] By way of example and not limitation, the positional relationship between the third transmission resource and the second transmission resource includes at least one of the following:

[0090] The third transmission resource and the second transmission resource are not adjacent in the time domain; the third transmission resource and the second transmission resource are adjacent in the time domain; the starting position of the frequency domain of the third transmission resource is the same as the starting position of the frequency domain of the second transmission resource; the center position of the frequency domain of the third transmission resource is the same as the center position of the frequency domain of the second transmission resource; the ending position of the frequency domain of the third transmission resource is the same as the ending position of the frequency domain of the second transmission resource.

[0091] In this context, the temporal adjacency between the third transmission resource and the second transmission resource means that the temporal end position of the second transmission resource is adjacent to the temporal start position of the third transmission resource.

[0092] In part (f) of Figure 3, the third transmission resource and the second transmission resource are not adjacent in the time domain, and the frequency domain center position of the third transmission resource is the same as that of the second transmission resource.

[0093] In part (g) of Figure 3, the third transmission resource and the second transmission resource are not adjacent in the time domain, and the starting position of the frequency domain of the third transmission resource is the same as that of the second transmission resource.

[0094] In part (h) of Figure 3, the third transmission resource and the second transmission resource are not adjacent in the time domain, and the frequency domain end position of the third transmission resource is the same as that of the second transmission resource.

[0095] A set of transmission resource types:

[0096] In some embodiments, a set of transmission resources is a common transmission resource shared by multiple terminal devices; or, a set of transmission resources is a group transmission resource shared by a group of terminal devices; or, a set of transmission resources is a proprietary transmission resource used by a terminal device.

[0097] In some embodiments, when a set of transmission resources is a common transmission resource shared by multiple terminal devices or a group transmission resource shared by a group of terminal devices, the other transmission resources in the set of transmission resources include a second transmission resource. 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.

[0098] In some embodiments, when a set of transmission resources is a common transmission resource shared by multiple terminal devices or a group transmission resource shared by a group of terminal devices, other transmission resources in the set of transmission resources include a third transmission resource, which is used for terminal transmission of random access sequences.

[0099] 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 own 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.

[0100] 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.

[0101] 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.

[0102] The network device is configured with a set of transmission resources for transmitting common DCI and / or common downlink data. 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.

[0103] In some embodiments, multiple terminal devices detect whether there is first indication information on the first transmission resource based on the same common sequence.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] In some embodiments, 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, wherein the second group transmission resource is used to transmit group common DCI and group common downlink data.

[0110] Optionally, the terminal equipment group includes all terminal equipment within the cell, and the first transmission resource of the group and the second transmission resource of the group can also be referred to as the shared first transmission resource and the shared second transmission resource.

[0111] For example, public DCI and public 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) information, uplink transmission cancellation indication information, and wake-up indication information.

[0112] In some embodiments, the network device configures a user-specific first transmission resource and a user-specific second transmission resource for each terminal device, which are used to transmit the user-specific DCI and user-specific downlink data corresponding to each terminal device, respectively.

[0113] 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.

[0114] For example, Figure 4 illustrates a schematic diagram of configuring transmission resources according to 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 common second transmission resources; the group transmission resources include two groups of first transmission resources and group second transmission resources; and the dedicated transmission resources include eight groups of dedicated first transmission resources and dedicated second transmission resources. For 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 common second transmission resources, one group of group first transmission resources and 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 group of transmission resources into different types of transmission resources, when the network device configures at least one of common transmission resources, group transmission resources, and dedicated transmission resources, the scope of detection by the terminal device is narrowed, and detection efficiency is improved.

[0115] First instruction message:

[0116] In some embodiments, the first transmission resource is used to transmit first indication information, the second transmission resource is used to transmit downlink control information (DCI) or PDCCH, or downlink data, and the third transmission resource is used to transmit uplink data and / or feedback information.

[0117] Figure 5 shows a schematic diagram of the indication method of the first indication information provided in an exemplary embodiment of this application.

[0118] In some embodiments, the first indication information is used to indicate transmission content on other transmission resources, and the first indication information is used to indicate at least one of the following:

[0119] Method 1: Indicate that no transmission is performed on the second transmission resource.

[0120] If the first indication information indicates that no transmission is to be performed on the second transmission resource, the terminal device does not need to perform detection on the second transmission resource;

[0121] 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.

[0122] 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.

[0123] Method 2: Instruct the transmission of DCI or PDCCH on the second transmission resource.

[0124] In some embodiments, DCI or PDCCH is received on a second transport resource based on first indication information.

[0125] 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.

[0126] By only detecting PDCCH on the second transmission resource when the first indication information indicates that DCI or PDCCH is being transmitted on the second transmission resource, it is not necessary to continuously detect PDCCH on all second transmission resources, which reduces the complexity of detection and achieves the effect of energy saving and consumption reduction.

[0127] 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.

[0128] Method 3: Instruct the second transmission resource to transmit uplink and downlink data.

[0129] In some embodiments, the terminal device receives downlink data on the second transmission resource based on first indication information. Optionally, if there is no indication that downlink data is being transmitted on the second transmission resource, it is not necessary to detect downlink data on the second transmission resource.

[0130] When the first instruction information indicates that the first downlink data is to be transmitted on the second transmission resource, the terminal device detects the downlink data on the second transmission resource.

[0131] Optionally, the downlink data is carried via PDSCH;

[0132] Optionally, a third value, a third state, or a third sequence is determined based on the first indication information, and downlink data is transmitted on the second transmission resource based on the third value, the third state, or the third sequence.

[0133] Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the first downlink data are determined based on protocol predefined information or network configuration information. In some embodiments, the transmission parameters include at least one of the following:

[0134] The modulation scheme or modulation and coding scheme (MCS) level corresponding to the downlink data; the coding scheme corresponding to the downlink data; the coding rate corresponding to the downlink data; the MCS table corresponding to the first downlink data; the number of layers corresponding to the downlink data; the antenna port information corresponding to the downlink data; and the demodulation reference signal (DMRS) information corresponding to the downlink data.

[0135] The TBS can be configured in the network. 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 redundant bits.

[0136] Optionally, the DMRS information corresponding to the downlink data is determined through network configuration information, and 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 the DMRS sequence initialization information.

[0137] In some embodiments, the first downlink data corresponds to small packet transmission. Small packet transmission can be understood as a transport block size less than or equal to a threshold value, which is determined based on protocol predefined information or network configuration information.

[0138] Method 4: Instruct the second transmission resource to transmit downlink data and the third transmission resource to transmit feedback information.

[0139] In some embodiments, downlink data is received on a second transmission resource based on first indication information, and feedback information corresponding to the downlink data is transmitted on a third transmission resource.

[0140] When the first indication information instructs the transmission of downlink data on the second transmission resource and the third transmission resource instructs the transmission of feedback information, the terminal device detects the downlink data on the second transmission resource. Optionally, the downlink data is carried via the PDSCH.

[0141] The terminal device transmits feedback information, such as Hybrid Automatic Repeat Request (HARQ) information, on the third transmission resource. The HARQ information is used to indicate whether the downlink data has been received correctly. The HARQ information includes ACK or NACK.

[0142] Optionally, a fourth value, a fourth state, or a fourth sequence is determined based on the first indication information, and downlink data is transmitted on the second transmission resource based on the fourth value, the fourth state, or the fourth sequence; and feedback information is transmitted on the third transmission resource.

[0143] Method 5: Instruct the second transmission resource to transmit downlink data, and the third transmission resource to transmit feedback information and / or uplink data.

[0144] When the first indication information indicates that downlink data is transmitted on the second transmission resource and feedback information and / or uplink data is transmitted on the third transmission resource, the terminal device detects downlink data on the second transmission resource; and the terminal device transmits feedback information and / or uplink data on the third transmission resource, wherein the feedback information is used to indicate whether the downlink data has been correctly received.

[0145] Optionally, a fifth value, a fifth state, or a fifth sequence is determined based on the first indication information, and downlink data is transmitted on the second transmission resource based on the fifth value, the fifth state, or the fifth sequence; feedback information and uplink data are transmitted on the third transmission resource.

[0146] In some embodiments, the feedback information and the first uplink data are multiplexed. The feedback information is carried through the MAC CE, and the MAC CE and the first uplink data are carried through the PUSCH. The first uplink data is carried through the PUSCH, and the feedback information and the PUSCH are multiplexed. That is, the feedback information and the PUSCH correspond to different resources in the third transmission resources.

[0147] Optionally, the first uplink data corresponds to a small packet transmission. Small packet transmission can be understood as a transmission block size less than or equal to a threshold value, which is determined based on protocol predefined information or network configuration information.

[0148] Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the first uplink data are determined based on protocol definition information or network configuration information.

[0149] Method 6: Indicates that uplink data is transmitted on the third transmission resource.

[0150] In some embodiments, uplink data is transmitted on a third transmission resource based on first indication information.

[0151] When the first instruction information indicates that uplink data should be transmitted on the third transmission resource, the terminal device transmits uplink data on the third transmission resource.

[0152] Optionally, uplink data is carried via PUSCH;

[0153] Optionally, a sixth value, a sixth state, or a sixth sequence is determined based on the first indication information, and uplink data is transmitted on the third transmission resource based on the sixth value, the sixth state, or the sixth sequence.

[0154] In some embodiments, the network device configures a third transmission resource for the terminal device to perform uplink transmission. The network device sends a first indication message to the terminal device through the first transmission resource to indicate whether the terminal device can perform uplink transmission on the third transmission resource.

[0155] For example, the network device configures a third transmission resource for the terminal device. The third transmission resource is an uplink configuration grant (UL Configured Grant, UL CG) resource, including a type 1 uplink configuration grant resource or a type 2 uplink configuration grant resource, or other types of uplink configuration grant resources. When the network device sends a first indication information to the terminal indicating a sixth value, the terminal can use the third transmission resource to send uplink data.

[0156] Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the uplink data are determined based on protocol predefined information or network configuration information. In some embodiments, the transmission parameters include at least one of the following:

[0157] The MCS level corresponding to the uplink data; the encoding method corresponding to the uplink data; the encoding rate corresponding to the uplink data; the number of layers corresponding to the uplink data; the antenna port information corresponding to the uplink data; and the demodulation reference signal information (DMRS information) corresponding to the uplink data.

[0158] The TBS can be configured in the network. 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 redundant bits.

[0159] Optionally, the DMRS information corresponding to the uplink data is determined by the network configuration information, and 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 the DMRS sequence initialization information.

[0160] In some embodiments, the first uplink data corresponds to a small packet transmission. A small packet transmission can be understood as a transport block size less than or equal to a threshold value, which is determined based on protocol predefined information or network configuration information.

[0161] Characteristics of the first instruction information:

[0162] 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. The advantages of sending the first indication information by sequence are: the terminal device can determine the information indicated by the first indication information based on sequence detection (such as sequence correlation detection), avoiding decoding processing, and reducing the terminal's power consumption and processing latency.

[0163] Optionally, the length of the sequence used to carry the first indication information is determined in the following way:

[0164] Determined based on protocol definition information;

[0165] Determined based on network configuration information;

[0166] • Determined based on the size of the frequency domain resources included in the first transmission resource.

[0167] For example, the first transmission resource includes M subcarriers or resource elements (REs), and the sequence length L corresponds to the largest prime number less than or equal to M, or the sequence length L corresponds to the largest prime number less than or equal to (M / A), where A is a positive integer, such as A = 2 or 4. For example, M = 60, L = 59; for another example, M = 72, L = 71; for yet another example, M = 120, L = 113.

[0168] The first indication information is used to indicate the first value:

[0169] In some embodiments, the first indication information is used to indicate a first value, which is associated with the transmitted content.

[0170] Optionally, the correspondence between the first value and the transmitted content is determined through protocol predefined information or network configuration information.

[0171] For example, the first indication information is used to indicate three values ​​of the first value, and the correspondence between the first value and the transmitted content is shown in Table 3:

[0172] Table 3

[0173] The first indication information is carried through a sequence:

[0174] In some embodiments, the first indication information is carried by a sequence, and the sequence index of the sequence is associated with the transmitted content.

[0175] Optionally, the correspondence between sequence indexes and transmitted content can be determined through protocol predefined information or network configuration information.

[0176] For example, the first indication information is carried by three sequences, and the correspondence between the sequence index and the transmitted content is shown in Table 4.

[0177] Table 4

[0178] For example, the first indication information is used to indicate the six values ​​of the first value. The correspondence between the first value and the transmission content is shown in Table 5. "No transmission" means that there is no transmission on the transmission resource, or "not involved" means that the information is not used to indicate the transmission on the transmission resource.

[0179] Table 5

[0180] For example, the first indication information is carried by 6 sequences, and the correspondence between the sequence index and the transmitted content is shown in Table 6.

[0181] Table 6

[0182] The second transmission resource is used to transmit DCI, PDCCH or downlink data. The terminal device determines whether to detect DCI, PDCCH or downlink data on the second transmission resource based on the first indication information.

[0183] (1) The second transmission resource is used to transmit DCI or PDCCH.

[0184] In some embodiments, DCI is carried by 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.

[0185] In some embodiments, where the first indication information is used to indicate the transmission of DCI or downlink control channel on the second transport resource, at least one of the following information is determined based on protocol predefined information or network configuration information:

[0186] The DCI format corresponding to the DCI; the number of bits corresponding to the DCI; the radio network temporary identifier associated with the DCI or downlink control channel; the coding method corresponding to the DCI or downlink control channel; the coding rate corresponding to the DCI or downlink control channel; the number of CCEs corresponding to the DCI or downlink control information; the aggregation level corresponding to the DCI or downlink control channel; and the number of candidate PDCCHs associated with the aggregation level.

[0187] The number of bits corresponding to DCI corresponds to the maximum number of bits, and the encoding methods include Polar code, Low Density Parity Check code (LDPC), or small block length encoding.

[0188] (2) The second transmission resource is used to transmit downlink data.

[0189] In some embodiments, the second transport resource is used to transmit downlink data, which is carried by the PDSCH.

[0190] Since the first indication information does not include transmission resource indication information and transmission parameter indication information, the transmission parameters corresponding to the downlink data are determined based on protocol predefined information or network configuration information.

[0191] In some embodiments, when the first indication information is used to indicate the transmission of downlink data on the second transmission resource, at least one of the following information is determined based on protocol predefined information or network configuration information:

[0192] The following information is required: the TBS corresponding to the downlink data; the MCS table corresponding to the downlink data; the modulation scheme or MCS level corresponding to the downlink data; the coding scheme corresponding to the downlink data; the coding rate corresponding to the downlink data; the number of layers corresponding to the downlink data; the antenna port information corresponding to the downlink data; the rate matching information corresponding to the downlink data; the DMRS information corresponding to the downlink data; the number of Physical Resource Blocks (PRBs) included in the resource block group; and the PRB binding size indication information.

[0193] The TBS can be configured in 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 redundant bits.

[0194] 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.

[0195] In some embodiments, the second transport resource is used only for transmitting small data packets, or the second transport resource is used only for small data transmission (SDT). A small data packet can be understood as a transport block size (TBS) less than or equal to a threshold value, which is determined based on protocol predefined information or network configuration information.

[0196] The third transmission resource is used to transmit feedback information and / or uplink data.

[0197] The terminal device determines, based on the first indication information, whether to transmit feedback information, uplink data, or both feedback information and uplink data on the third transmission resource.

[0198] (1) The third transmission resource is used to transmit feedback information.

[0199] In some embodiments, if a first indication message sent on a first transmission resource indicates that downlink data is transmitted on a second transmission resource, the terminal detects the first downlink data on the second transmission resource and provides feedback. Since there is a correlation between the first transmission resource and the third transmission resource, the terminal device can determine the third transmission resource based on the first transmission resource and transmit the feedback information (such as HARQ feedback information ACK or NACK) corresponding to the first downlink data on the third transmission resource.

[0200] It should be understood that, in the embodiments of this application, the feedback information transmitted on the third transmission resource may include one or more of the following: HARQ feedback information; Precoding Matrix Indicator (PMI); Rank Indicator (RI); Channel State Information (CSI); Channel Interference Information (CLI); Reference Signal Index Information; and Link Recovery Request (LRR). The specific type of feedback information can be determined based on network configuration information or the first indication information. Among these, the HARQ feedback information includes acknowledgment feedback or denial feedback corresponding to downlink data transmitted on the second transmission resource or the downlink shared channel.

[0201] Optionally, the feedback information transmitted on the third transmission resource is carried through the Physical Uplink Control Channel (PUCCH), and the PUCCH format and / or PUCCH resources are determined through network configuration information or first indication information.

[0202] In some embodiments, where multiple second transmission resources correspond to one third transmission resource, the feedback information transmitted on the third transmission resource is feedback information for downlink data on the second transmission resource.

[0203] In some embodiments, the first transmission resource and the third transmission resource have a many-to-one correspondence, or the second transmission resource and the third transmission resource have a many-to-one correspondence, that is, n (n greater than 1) second transmission resources correspond to one third transmission resource. In this case, the third transmission resource is used to transmit feedback information corresponding to the downlink data on the n second transmission resources. Specific feedback methods may include the following:

[0204] Feedback Method 1: Bundling Feedback of n Feedback Messages: Perform a bit AND operation or a bit OR operation on the feedback messages corresponding to the downlink data transmitted on the n second transmission resources to obtain 1 bit of information, and use this 1 bit of information for feedback.

[0205] Feedback Method 2: The feedback information includes n information fields (n bits), which correspond to downlink data on n second transmission resources respectively.

[0206] If the terminal device detects downlink data on the i-th second transmission resource (detection successful or detection failed), the terminal device will send an ACK or NACK response on the i-th bit; if the terminal device does not detect downlink data on the i-th second transmission resource, the terminal device will not send a response on the i-th bit (e.g., fill in the specified character NULL) or will send a NACK or ACK response.

[0207] Figure 6 illustrates a schematic diagram of a feedback method provided by an exemplary embodiment of this application. The second and third transmission resources have a many-to-one correspondence; in Figure 6, four second transmission resources correspond to one third transmission resource, and the feedback information corresponding to the downlink data on the four second transmission resources is fed back through the same third transmission resource.

[0208] Assume that the first second transmission resource transmits downlink data 1, the terminal device detects it successfully and sends an ACK message; the fourth second transmission resource transmits downlink data 2, the terminal device fails to detect it and sends a NACK message; no transmission occurs on the second and third second transmission resources.

[0209] If feedback method 1 is adopted, multiple feedback information are bound together (e.g., bit AND operation) for feedback. Since the feedback information corresponding to the fourth second transmission resource is NACK, the feedback information corresponds to 1 bit NACK.

[0210] If feedback method 2 is used, the feedback information of the third transmission resource corresponds to 4 bits, which correspond to the downlink transmissions on the four second transmission resources respectively. Downlink data 1 and downlink data 2 correspond to the first and fourth bits of the 4 bits respectively. The second and third bits of the 4 bits correspond to the second and third second transmission resources. Since no transmission is performed on these two second transmission resources, their corresponding feedback information bits are empty (or NULL).

[0211] Optionally, if the first indication information indicates that the first downlink data is transmitted on the second transmission resource and the terminal device fails to detect the first downlink data, the terminal device sends a NACK on the third transmission resource; if the terminal device successfully detects the first downlink data, the terminal device does not provide feedback on the third transmission resource (i.e., does not send an ACK).

[0212] Optionally, if the first indication information indicates that the first downlink data is transmitted on the second transmission resource and the terminal device successfully detects the first downlink data, the terminal device sends an ACK on the third transmission resource; if the terminal device fails to successfully detect the first downlink data, the terminal device does not provide feedback on the third transmission resource (i.e., does not send a NACK).

[0213] (2) The third transmission resource is used to transmit uplink data.

[0214] In some embodiments, when the first indication information is used to indicate the transmission of uplink data on a third transport resource, at least one of the following information is determined based on protocol predefined information or network configuration information:

[0215] The TBS corresponding to the uplink data; the MCS table corresponding to the uplink data; the modulation scheme or MCS level corresponding to the uplink data; the coding scheme corresponding to the uplink data; the coding rate corresponding to the uplink data; the number of layers corresponding to the uplink data; the antenna port information corresponding to the uplink data; and the DMRS information corresponding to the uplink data.

[0216] Optionally, the DMRS information corresponding to the uplink 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 uplink data is determined based on protocol predefined information, network configuration information, or first indication information.

[0217] (3) The third transmission resource is used to transmit feedback information and uplink data.

[0218] In some implementations, if the second transmission resource is used to transmit downlink data, the feedback information corresponding to the downlink data (such as HARQ feedback information ACK or NACK) is transmitted through the third transmission resource; if the third transmission resource simultaneously transmits uplink data, then the HARQ feedback information and the uplink data are transmitted simultaneously through the third transmission resource. Specifically, the feedback information and the uplink data can be multiplexed in the following way:

[0219] • Feedback information is carried via the MAC CE, and the MAC CE and uplink data are carried via the PUSCH;

[0220] • Uplink data is carried through PUSCH. The feedback information and PUSCH are multiplexed, meaning that the feedback information and PUSCH correspond to different resources in the third transmission resource.

[0221] Optionally, uplink data corresponds to small packet transmission. A small packet can be understood as a transport block size (TBS) less than or equal to a threshold value, which is determined based on protocol predefined information or network configuration information.

[0222] Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the uplink data are determined based on protocol definition information or network configuration information; these transmission parameters are as described in the previous section and will not be repeated here.

[0223] Figure 7 illustrates a flowchart of a communication 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:

[0229] The correspondence between the first transmission resource and the third transmission resource is one-to-one or many-to-one;

[0302] In summary, the method provided in this application involves a network device sending first indication information on a first transmission resource. This first indication information indicates the transmission content on other transmission resources. These other transmission resources include a second transmission resource for downlink transmission and a third transmission resource for uplink transmission. The first indication information is based on sequence bearers. The terminal device performs detection according to the first indication information, eliminating the need for blind detection. Detection on other transmission resources is only performed when necessary, avoiding wasted energy due to blind detection and promoting energy conservation and consumption reduction in the terminal device.

[0303] Next, based on the embodiments shown in Figures 7 and 8, we will further introduce the first indication information used to indicate the transmission parameters corresponding to the transmission content on other transmission resources.

[0304] In some embodiments, the terminal device determines the transmission parameter values ​​corresponding to the transmission content on other transmission resources from among multiple or multiple sets of candidate parameter values ​​based on the first information associated with the first indication information. The first indication information is carried by a sequence, and the first information associated with the first indication information is sequence-related information. Optionally, the first information associated with the first indication information includes at least one of: the length of the sequence, the frequency domain resource corresponding to the sequence, the time domain resource corresponding to the sequence, the sequence index corresponding to the sequence, or the sequence group index.

[0305] The following explanation uses other transmission resources, including the second transmission resource, as an example.

[0306] Optionally, other transmission resources can be used as an example of the second transmission resource. The second transmission resource is a transmission resource configured by the network device for the terminal device, and it is used for downlink transmission. Optionally, the second transmission resource is used to transmit downlink control information and / or downlink data. The terminal device detects at least one of downlink control information, downlink control channel, downlink data, downlink shared channel, and downlink data channel on the second transmission resource based on the first indication information. The downlink control information is carried through the downlink control channel; or, the downlink control information is carried through the downlink shared channel.

[0307] The first indication information is used to indicate the value of the transmission parameters corresponding to the transmission content on the second transmission resource, wherein the transmission parameters include at least one of the following:

[0308] • Downlink control information or the aggregation level corresponding to the downlink control channel;

[0309] • The number of CCEs corresponding to downlink control information or downlink control channels;

[0310] • The amount of resources used to transmit downlink control information or downlink control channels;

[0311] • The modulation scheme corresponding to the downlink data;

[0312] • The MCS level corresponding to the downlink data;

[0313] • The MCS table corresponding to the downlink data;

[0314] • TBS corresponding to downlink data.

[0315] In some embodiments, the value of the transmission parameter corresponding to the transmission content on the second transmission resource is determined based on the first information associated with the first indication information. This can be understood as determining the value of the transmission parameter indicated by the transmission content on the second transmission resource based on the first information associated with the first indication information, or it can also be understood as indicating the value of the transmission parameter corresponding to the transmission content on the second transmission resource based on the first information associated with the first indication information. Optionally, the following five different indication methods can be used to indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource.

[0316] Indication Method 1: Indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource based on the length of the sequence;

[0317] Indication Method 2: Based on the frequency domain resource indication of the sequence, indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0318] Indication Method 3: Based on the time-domain resource indication of the sequence, indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0319] Indication Method 4: Based on the sequence index corresponding to the sequence, indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0320] Indication Method 5: Based on the sequence group index corresponding to the sequence, indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource.

[0321] The five different instruction methods will be introduced below.

[0322] Regarding the above instruction method one:

[0323] In some embodiments, the length of the sequence indicates the value of the transmission parameter corresponding to the transmission content on the second transmission resource.

[0324] Optionally, taking downlink control information or downlink control channel as an example, the value of the aggregation level corresponding to the downlink control information or downlink control channel, the value of the number of CCEs, and the value of the number of resources are indicated based on the length of the sequence.

[0325] Optionally, taking downlink data as an example, the transmission content on the second transmission resource is indicated by at least one of the following: the value of the modulation scheme corresponding to the downlink data based on the sequence length; the value of the MCS level; the value of the MCS table; and the value of the TBS.

[0326] In some embodiments, the network device configures sequences of different lengths for transmitting first indication information, and the terminal device performs detection based on sequences of different lengths. Optionally, taking the first indication information determining that the transmission content on the second transmission resource is downlink control information or a downlink control channel as an example, the terminal device determines at least one of the following based on the detected sequence length corresponding to the first indication information: the aggregation level of the downlink control information or the downlink control channel; the number of CCEs; and the number of resources. Optionally, taking the first indication information determining that the transmission content on the second transmission resource is downlink data as an example, the terminal device determines at least one of the following based on the detected sequence length corresponding to the first indication information: the modulation scheme of the downlink data; the MCS level; the MCS table; and the TBS.

[0327] 1. The transmission content on the second transmission resource includes downlink control information or downlink control channel.

[0328] In some embodiments, a first transmission resource is used to transmit first indication information, which is used to determine (or be understood as indicating) that the content transmitted on a second transmission resource is downlink control information or a downlink control channel. The first indication information is carried by a sequence. Optionally, the network device can configure different sequence lengths, where different sequence lengths correspond to different aggregation levels corresponding to downlink control information or downlink control channels; or, different numbers of CCEs; or, different numbers of resources.

[0329] It should be noted that the lengths of different sequences correspond to different aggregation levels for downlink control information or downlink control channels. This can be understood as determining the aggregation level based on the sequence length. Similarly, the lengths of different sequences correspond to different numbers of CCEs for downlink control information or downlink control channels. Finally, the lengths of different sequences correspond to the amount of resources associated with downlink control information or downlink control channels.

[0330] Different aggregation levels can be considered as different values ​​of aggregation level; different CCE quantities can be considered as different values ​​of CCE quantity; different resource quantities can be considered as different values ​​of resource quantity. In the following text, "different aggregation levels" can be understood as "different values ​​of aggregation level"; "different CCE quantities" can be understood as "different values ​​of CCE quantity"; "different resource quantities" can be understood as "different values ​​of resource quantity".

[0331] In some embodiments, the first information associated with the first indication information includes the length of the sequence. The sequence length has A1 possible values, and the transmission parameters (e.g., aggregation level, number of CCEs, number of resources) have A2 possible values. A first correspondence exists between the sequence length values ​​and the transmission parameter values. Optionally, the first correspondence is determined based on protocol predefined information or network configuration information. Here, A1 is an integer greater than or equal to 1, and A2 is an integer greater than or equal to 1.

[0332] 1) Different sequence lengths correspond to different aggregation levels.

[0333] In some embodiments, different sequence lengths correspond to different aggregation levels. This can also be understood as different sequence lengths corresponding to different aggregation level values, i.e., the aggregation level value is determined based on the sequence length.

[0334] In some embodiments, the network device is configured with different sequence lengths, each corresponding to a different aggregation level of the downlink control channel. The downlink control channel is aggregated from one or more CCEs, and the number of CCEs represents 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}.

[0335] In some embodiments, taking the frequency domain resource size corresponding to the second transmission resource as N as an example, the granularity of frequency domain resource partitioning can optionally be bandwidth, physical resource block (PRB), bandwidth part (BWP), subband, subchannel, or subcarrier. For example, taking subcarrier partitioning as an example, the frequency domain resource size corresponding to the second transmission resource is N, that is, the number of frequency domain subcarriers is N. The relationship between the length of different sequences and the aggregation level values ​​configured by the network device is shown in Table 7.

[0336] Table 7

[0337] For example, the first information includes the length of the sequence, which has four possible values, and the aggregation level also has four possible values. There is a first correspondence between the sequence length and the aggregation level. Optionally, when the sequence length is a first length, it corresponds to a first aggregation level; when the sequence length is a second length, it corresponds to a second aggregation level; when the sequence length is a third length, it corresponds to a third aggregation level; and when the sequence length is a fourth length, it corresponds to a fourth aggregation level. The first correspondence between the sequence length and the aggregation level is determined based on protocol predefined information or network configuration information.

[0338] The length of the above sequence is determined based on the frequency domain resource size corresponding to the second transmission resource. For example, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to the frequency domain resource size N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 4, for example, the third length corresponds to the largest prime number less than N / 4 or the third length is equal to N / 4; the fourth length is determined based on N / 8, for example, the fourth length corresponds to the largest prime number less than N / 8 or the fourth length is equal to N / 8. Alternatively, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 3, for example, the third length corresponds to the largest prime number less than N / 3 or the third length is equal to N / 3; the fourth length is determined based on N / 4, for example, the fourth length corresponds to the largest prime number less than N / 4 or the fourth length is equal to N / 4. The aforementioned first, second, third, and fourth aggregation levels each include one of the aggregation levels {1, 2, 4, 8, 16}. Optionally, the first, second, third, and fourth aggregation levels may not be completely identical or may each be different; this application does not impose any limitation on this.

[0339] For example, the frequency domain resource N corresponding to the second transmission resource is 36. The first length of the sequence is the largest prime number less than N, i.e., the first length is 31. The second length of the sequence is the largest prime number less than N / 2, i.e., the second length is 17. The third length of the sequence is the largest prime number less than N / 4, i.e., the third length is 7. The fourth length of the sequence is the largest prime number less than N / 8, i.e., the fourth length is 3. The first aggregation level is 16, the second aggregation level is 8, the third aggregation level is 2, and the fourth aggregation level is 1. Optionally, different sequence lengths correspond to different aggregation levels. For example, a sequence length of 31 corresponds to aggregation level 16, a sequence length of 17 corresponds to aggregation level 8, a sequence length of 7 corresponds to aggregation level 2, and a sequence length of 3 corresponds to aggregation level 1. The above are merely illustrative examples and do not constitute a limitation.

[0340] It should be noted that Table 7 above is merely an exemplary illustration of the first correspondence between sequence length and aggregation level values, and the method implemented in this application is not limited to the correspondence in Table 7. In some embodiments, the correspondence of network configurations only includes a portion of the content in the table above, such as only any two rows in the table; in some embodiments, the correspondence of network configurations includes K sequence lengths, and the corresponding aggregation level values ​​are also K, where K is an integer greater than or equal to 1.

[0341] 2) Different sequence lengths correspond to different numbers of CCEs

[0342] In some embodiments, different sequence lengths correspond to different CCE numbers. This can also be understood as different sequence lengths corresponding to different CCE values, i.e., the CCE number is determined based on the sequence length.

[0343] In some embodiments, network devices are configured with different sequence lengths, each corresponding to a different number of Control Center Equipment (CCEs). A downlink control channel is composed of one or more CCEs, and the transmission resources of a downlink control channel include one or more CCEs. Optionally, a CCE is the basic 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 occupied by the downlink control channel, 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.

[0344] For example, taking the subcarrier as the granularity of frequency domain resource partitioning, the size of the frequency domain resource corresponding to the second transmission resource is N, that is, the number of frequency domain subcarriers is N. The relationship between the length of different sequences and the number of CCEs configured by the network device is shown in Table 8.

[0345] Table 8

[0346] For example, the first information includes the length of the sequence. Taking the sequence length and the number of CCEs as examples, which both have four possible values, there is a first correspondence between the sequence length and the number of CCEs. Optionally, when the sequence length is a first length, it corresponds to a first number of CCEs; when the sequence length is a second length, it corresponds to a second number of CCEs; when the sequence length is a third length, it corresponds to a third number of CCEs; and when the sequence length is a fourth length, it corresponds to a fourth number of CCEs. The first correspondence between the sequence length and the number of CCEs is determined based on protocol predefined information or network configuration information.

[0347] The length of the above sequence is determined based on the frequency domain resource size corresponding to the second transmission resource. For example, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 4, for example, the third length corresponds to the largest prime number less than N / 4 or the third length is equal to N / 4; the fourth length is determined based on N / 8, for example, the fourth length corresponds to the largest prime number less than N / 8 or the fourth length is equal to N / 8. Alternatively, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 3, for example, the third length corresponds to the largest prime number less than N / 3 or the third length is equal to N / 3; the fourth length is determined based on N / 4, for example, the fourth length corresponds to the largest prime number less than N / 4 or the fourth length is equal to N / 4. The number of first, second, third, and fourth CCEs mentioned above includes one of {1, 2, 4, 8, 16}. Optionally, the number of first, second, third, and fourth CCEs may not be exactly the same or may be different, and this application does not limit this.

[0348] For example, the frequency domain resource N corresponding to the second transmission resource is 36. The first length of the sequence is the largest prime number less than N, i.e., the first length is 31. The second length of the sequence is the largest prime number less than N / 2, i.e., the second length is 17. The third length of the sequence is the largest prime number less than N / 4, i.e., the third length is 7. The fourth length of the sequence is the largest prime number less than N / 8, i.e., the fourth length is 3. The first CCE number is 16, the second CCE number is 8, the third CCE number is 2, and the fourth CCE number is 1. Optionally, different sequence lengths correspond to different numbers of CCEs. For example, a sequence length of 31 corresponds to 16 CCEs, a sequence length of 17 corresponds to 8 CCEs, a sequence length of 7 corresponds to 2 CCEs, and a sequence length of 3 corresponds to 1 CCE. The above are merely illustrative examples and do not constitute a limitation.

[0349] It should be noted that Table 8 above is merely an exemplary illustration of the first correspondence between the sequence length and the number of CCEs, and the method implemented in this application is not limited to the correspondence in Table 8. In some embodiments, the correspondence of network configurations 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 configurations includes K sequence lengths, and the corresponding number of CCEs also has K values, where K is an integer greater than or equal to 1.

[0350] 3) Different sequence lengths correspond to different resource quantities.

[0351] In some embodiments, different sequence lengths correspond to different resource quantities. This can also be understood as different sequence lengths corresponding to different resource quantity values, i.e., the resource quantity value is determined based on the sequence length.

[0352] In some embodiments, network devices are configured with different sequence lengths, each corresponding to a different number of resources (resources can also be called transmission resources). The number of resources refers to the amount of physical resources required to transmit specific information (such as control information or data information). The number of resources typically refers to the number of specific resources allocated to a particular transmission task, such as Physical Resource Blocks (PRBs) and Resource Elements (REs). Different transmission tasks may require different amounts of resources to meet their bandwidth, power, and reliability requirements. Optionally, the number of resources includes the number of time-domain resources and / or frequency-domain resources; for example, the number of resources includes the number of subcarriers and OFDM symbols.

[0353] In some embodiments, when downlink control information or a downlink control channel is transmitted on the second transmission resource, the code rate of the downlink control information can be adjusted by changing the number of resources carrying the downlink control information or the downlink control channel, thereby achieving link adaptive adjustment. The relationship between the length of different sequences and the number of resources configured by the network device is shown in Table 9.

[0354] Table 9

[0355] For example, the first information includes the length of the sequence. Taking the sequence length and the number of resources as examples, which each have four possible values, there is a first correspondence between the sequence length and the number of resources. Optionally, when the sequence length is a first length, it corresponds to a first number of resources (transmission resources); when the sequence length is a second length, it corresponds to a second number of resources; when the sequence length is a third length, it corresponds to a third number of resources; and when the sequence length is a fourth length, it corresponds to a fourth number of resources. The first correspondence between the sequence length and the number of resources is determined based on protocol predefined information or network configuration information.

[0356] For example, the number of resources can be represented as the number of frequency domain units, where frequency domain units include PRBs, subbands, subcarriers, resource units, RBGs, etc.

[0357] For example, the number of resources can be represented as the number of time-domain units, where time-domain units include time slots, OFDM symbols, etc.

[0358] For example, the number of resources can be represented as the number of REGs.

[0359] In some embodiments, the above-mentioned resource quantity is determined based on the quantity of the second transmission resource. For example, the first quantity corresponds to the quantity of all transmission resources included in the second transmission resource, the second quantity corresponds to the quantity of half of the transmission resources included in the second transmission resource, the third quantity corresponds to the quantity of one-quarter of the transmission resources included in the second transmission resource, and the fourth quantity corresponds to the quantity of one-eighth of the transmission resources included in the second transmission resource. This application does not limit this quantity.

[0360] The length of the above sequence is determined based on the frequency domain resource size corresponding to the second transmission resource. For example, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 4, for example, the third length corresponds to the largest prime number less than N / 4 or the third length is equal to N / 4; the fourth length is determined based on N / 8, for example, the fourth length corresponds to the largest prime number less than N / 8 or the fourth length is equal to N / 8. Alternatively, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 3, for example, the third length corresponds to the largest prime number less than N / 3 or the third length is equal to N / 3; the fourth length is determined based on N / 4, for example, the fourth length corresponds to the largest prime number less than N / 4 or the fourth length is equal to N / 4. Optionally, the first, second, third, and fourth quantities in Table 9 may not be exactly the same or may be different from each other, and this application does not impose any restrictions on this.

[0361] It should be noted that Table 9 above is merely an exemplary illustration of the first correspondence between the sequence length and the resource quantity values, and the method implemented in this application is not limited to the correspondence in Table 9. In some embodiments, the correspondence of network configurations 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 configurations includes a sequence length of K, and the corresponding resource quantity values ​​are also K, where K is an integer greater than or equal to 1.

[0362] 2. The transmission content on the second transmission resource includes downlink data.

[0363] In some embodiments, a first transmission resource is used to transmit first indication information, which is used to determine (or be understood as indicating) that the content transmitted on a second transmission resource is downlink data. The first indication information is carried by a sequence. Optionally, the network device can configure different sequence lengths, which correspond to different modulation orders used by the downlink data; or, different MCS tables; or, different MCS levels; or, different TBSs.

[0364] It should be noted that different sequence lengths correspond to different modulation orders used in the downlink data. This can be understood as determining the modulation order based on the sequence length. Similarly, different sequence lengths correspond to different MCS tables used in the downlink data. Likewise, different sequence lengths correspond to different MCS levels used in the downlink data. Finally, different sequence lengths correspond to different TBS values ​​used in the downlink data.

[0365] Different modulation orders can be considered as different values ​​of the modulation order; different MCS tables can be considered as different values ​​of the MCS table; different MCS levels can be considered as different values ​​of the MCS level; different TBSs can be considered as different values ​​of the TBS. In the following text, "different modulation orders" can be understood as "different values ​​of the modulation order" or "different modulation methods"; "different MCS tables" can be understood as "different values ​​of the MCS table"; "different MCS levels" can be understood as "different values ​​of the MCS level"; and "different TBSs" can be understood as "different values ​​of the TBS".

[0366] In some embodiments, the first information associated with the first indication information includes the length of the sequence. The sequence length has A1 possible values, and the transmission parameters (e.g., modulation scheme, MCS table, MCS level, TBS) have A2 possible values. A first correspondence exists between the sequence length values ​​and the transmission parameter values. Optionally, the first correspondence is determined based on protocol predefined information or network configuration information. Here, A1 is an integer greater than or equal to 1, and A2 is an integer greater than or equal to 1.

[0367] In some embodiments, when downlink data is transmitted on the second transmission resource, the link adaptive adjustment of downlink data transmission can be achieved by changing the modulation scheme (determined by the modulation order), MCS table, MCS level, or TBS corresponding to the downlink data.

[0368] For example, Table 10 shows the MCS table that supports 64QAM modulation. Based on Table 10, a preliminary introduction to modulation order, MCS level, MCS index and MCS table is given.

[0369] Table 10

[0370] The MCS index is a number or indicator used to identify a specific modulation and coding scheme in the MCS table. Optionally, each MCS index corresponds to a specific set of modulation schemes and coding rates. The modulation order refers to the order of the modulation scheme, used to indicate the number of bits included in the data signal, usually denoted by Qm. For example, QPSK (Quadrature Phase Shift Keying) has Qm=2, 16QAM has Qm=4, and 64QAM has Qm=6. Optionally, a higher modulation order usually provides a higher data transmission rate, but also requires higher channel quality. The target code rate is the effective code rate of the coding scheme, representing the ratio of information bits to coded bits, that is, how many bits in the encoded bitstream are actual data (effective data) bits. Spectral efficiency represents the amount of data transmitted per unit bandwidth. Spectral efficiency is related to the modulation order and the target code rate, reflecting the transmission capability of the communication system under given spectrum resources.

[0371] 1) Different sequence lengths correspond to different modulation methods

[0372] In some embodiments, different sequence lengths correspond to different modulation schemes. This can also be understood as different sequence lengths corresponding to different modulation scheme values, i.e., the modulation scheme value is determined based on the sequence length.

[0373] In some embodiments, the network device is configured with different sequence lengths, each corresponding to a different modulation scheme used for downlink data. These modulation schemes include, for example, QPSK / 16QAM / 64QAM / 256QAM / 1024QAM / 4096QAM. Optionally, the modulation scheme is determined based on the modulation order, which refers to the number of bits represented by each symbol in the modulation scheme. QPSK has a modulation order of 2, meaning each symbol represents 2 bits; 16QAM has a modulation order of 4, meaning each symbol represents 4 bits; 64QAM has a modulation order of 6, meaning each symbol represents 6 bits; 256QAM has a modulation order of 8, meaning each symbol represents 8 bits; 1024QAM has a modulation order of 10, meaning each symbol represents 10 bits; and 4096QAM has a modulation order of 12, meaning each symbol represents 12 bits. Optionally, a higher modulation order results in a larger amount of data transmitted per unit time, but also requires higher signal quality. The relationship between the length of different sequences and the modulation scheme in network device configurations is shown in Table 11.

[0374] Table 11

[0375] For example, the first information includes the length of the sequence. Taking the sequence length and modulation scheme as examples, which each have four possible values, there is a first correspondence between the sequence length and modulation scheme values. Optionally, when the sequence length is a first length, it corresponds to a first modulation scheme; when the sequence length is a second length, it corresponds to a second modulation scheme; when the sequence length is a third length, it corresponds to a third modulation scheme; and when the sequence length is a fourth length, it corresponds to a fourth modulation scheme. The first correspondence between the sequence length and the modulation scheme is determined based on protocol predefined information or network configuration information.

[0376] The length of the above sequence is determined based on the frequency domain resource size corresponding to the second transmission resource. For example, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 4, for example, the third length corresponds to the largest prime number less than N / 4 or the third length is equal to N / 4; the fourth length is determined based on N / 8, for example, the fourth length corresponds to the largest prime number less than N / 8 or the fourth length is equal to N / 8. Alternatively, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 3, for example, the third length corresponds to the largest prime number less than N / 3 or the third length is equal to N / 3; the fourth length is determined based on N / 4, for example, the fourth length corresponds to the largest prime number less than N / 4 or the fourth length is equal to N / 4. The above modulation scheme can employ different modulation schemes. The first modulation scheme, the second modulation scheme, the third modulation scheme, and the fourth modulation scheme can be any one of QPSK / 16QAM / 64QAM / 256QAM / 1024QAM / 4096QAM. Optionally, the first modulation scheme, the second modulation scheme, the third modulation scheme, and the fourth modulation scheme may not be completely identical or may be different from each other; this application does not impose any limitation on this.

[0377] For example, the frequency domain resource N corresponding to the second transmission resource is 36. The first length of the sequence is the largest prime number less than N, i.e., the first length is 31. The second length of the sequence is the largest prime number less than N / 2, i.e., the second length is 17. The third length of the sequence is the largest prime number less than N / 4, i.e., the third length is 7. The fourth length of the sequence is the largest prime number less than N / 8, i.e., the fourth length is 3. The first modulation scheme is 256QAM, the second modulation scheme is 64QAM, the third modulation scheme is 16QAM, and the fourth modulation scheme is QPSK. Optionally, different sequence lengths correspond to different modulation schemes; for example, a sequence length of 31 corresponds to the first modulation scheme 256QAM.

[0378] It should be noted that Table 11 above is merely an exemplary illustration of the first correspondence between sequence length and modulation scheme values, and the method implemented in this application is not limited to the correspondence in Table 11. 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 sequence lengths, and the corresponding modulation scheme values ​​are also K, where K is an integer greater than or equal to 1.

[0379] 2) Different sequence lengths correspond to different MCS tables.

[0380] In some embodiments, different sequence lengths correspond to different MCS tables. This can also be understood as different sequence lengths corresponding to different MCS table values, i.e., the MCS table value is determined based on the sequence length.

[0381] In some embodiments, the network device is configured with different sequence lengths, each corresponding to a different MCS table for the downlink data. MCS tables may include, for example, MCS tables supporting a maximum of 64QAM, a maximum of 256QAM, a maximum of 1024QAM, a maximum of 4096QAM, or MCS tables supporting low spectral efficiency.

[0382] 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 code rate. The relationship between the length of different sequences configured in network devices and the values ​​of the MCS table is shown in Table 12.

[0383] Table 12

[0384] For example, the first information includes the length of the sequence. Taking the example that the sequence length has four possible values ​​and the MCS table also has four possible values, there is a first correspondence between the sequence length values ​​and the MCS table values. Optionally, when the sequence length is a first length, it corresponds to a first MCS table; when the sequence length is a second length, it corresponds to a second MCS table; when the sequence length is a third length, it corresponds to a third MCS table; and when the sequence length is a fourth length, it corresponds to a fourth MCS table. The first correspondence between the sequence length and the MCS table is determined based on protocol predefined information or network configuration information.

[0385] The length of the above sequence is determined based on the frequency domain resource size corresponding to the second transmission resource. For example, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 4, for example, the third length corresponds to the largest prime number less than N / 4 or the third length is equal to N / 4; the fourth length is determined based on N / 8, for example, the fourth length corresponds to the largest prime number less than N / 8 or the fourth length is equal to N / 8. Alternatively, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 3, for example, the third length corresponds to the largest prime number less than N / 3 or the third length is equal to N / 3; the fourth length is determined based on N / 4, for example, the fourth length corresponds to the largest prime number less than N / 4 or the fourth length is equal to N / 4. The first, second, third, and fourth MCS tables mentioned above can be MCS tables that support a maximum of 64QAM, a maximum of 256QAM, a maximum of 1024QAM, a maximum of 4096QAM, or MCS tables that support low spectral efficiency. Optionally, the first, second, third, and fourth MCS tables may not be completely identical or may each be different; this application does not impose any limitations on this.

[0386] It should be noted that Table 12 above is merely an exemplary illustration of the first correspondence between sequence lengths and the values ​​in the MCS table, and the method implemented in this application is not limited to the correspondence in Table 12. In some embodiments, the correspondence of network configurations only includes a portion of the contents of the table above, such as only any two rows in the table; in some embodiments, the correspondence of network configurations includes K sequence lengths, and the corresponding MCS table values ​​are also K, where K is an integer greater than or equal to 1.

[0387] 3) Different sequence lengths correspond to different MCS levels.

[0388] In some embodiments, different sequence lengths correspond to different MCS levels. This can also be understood as different MCS level values ​​corresponding to different sequence lengths, i.e., the MCS level value is determined based on the sequence length.

[0389] In some embodiments, the network device is configured with different sequence lengths, each corresponding to a different MCS level (or MCS index) for the downlink data. The MCS index is a concrete 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. The relationship between the network settings for different sequence lengths and the values ​​of the MCS level is shown in Table 13.

[0390] Table 13

[0391] For example, the first information includes the length of the sequence. Taking the example that the sequence length has four possible values ​​and the MCS level also has four possible values, there is a first correspondence between the sequence length and the MCS level. Optionally, when the sequence length is a first length, it corresponds to a first MCS level; when the sequence length is a second length, it corresponds to a second MCS level; when the sequence length is a third length, it corresponds to a third MCS level; and when the sequence length is a fourth length, it corresponds to a fourth MCS level. The first correspondence between the sequence length and the MCS level is determined based on protocol predefined information or network configuration information.

[0392] The length of the above sequence is determined based on the frequency domain resource size corresponding to the second transmission resource. For example, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 4, for example, the third length corresponds to the largest prime number less than N / 4 or the third length is equal to N / 4; the fourth length is determined based on N / 8, for example, the fourth length corresponds to the largest prime number less than N / 8 or the fourth length is equal to N / 8. Alternatively, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 3, for example, the third length corresponds to the largest prime number less than N / 3 or the third length is equal to N / 3; the fourth length is determined based on N / 4, for example, the fourth length corresponds to the largest prime number less than N / 4 or the fourth length is equal to N / 4. The aforementioned first MCS level, second MCS level, third MCS level, and fourth MCS level correspond to an MCS level in the MCS table, for example, to an MCS level (or MCS index) in an MCS table that supports a maximum of 64QAM. Optionally, the first MCS level, second MCS level, third MCS level, and fourth MCS level may not be exactly the same or may be different from each other, and this application does not limit this.

[0393] It should be noted that Table 13 above is merely an exemplary illustration of the first correspondence between sequence length and MCS level values, and the method implemented in this application is not limited to the correspondence in Table 13. In some embodiments, the correspondence of network configurations only includes a portion of the content in the table above, such as only any two rows in the table; in some embodiments, the correspondence of network configurations includes K sequence lengths, and the corresponding MCS level values ​​are also K, where K is an integer greater than or equal to 1.

[0394] 4) Different sequence lengths correspond to different TBSs

[0395] In some embodiments, different sequence lengths correspond to different TBS values, which can also be understood as different TBS values ​​corresponding to different sequence lengths, i.e., the TBS value is determined based on the sequence length.

[0396] In some embodiments, network devices are configured with different sequence lengths, each corresponding to a different Transport Block Size (TBS) for downlink data. TBS is a parameter describing the physical layer transport block size, representing the amount of data transmitted under a specific modulation and coding scheme. TBS depends on the size of the resource block allocated to the second transport resource, including the number of subcarriers and OFDM symbols. When the second transport resource is used to transmit downlink data, the size of the TBS affects the reliability of the transmission. For example, with a fixed second transport resource size, a larger TBS requires a higher code rate or modulation order, resulting in a shorter transmission distance or lower transmission reliability; conversely, a smaller TBS requires a lower code rate or modulation order, resulting in a longer transmission distance or higher transmission reliability. The relationship between the network device's configured sequence lengths and the TBS values ​​is shown in Table 14.

[0397] Table 14

[0398] For example, the first information includes the length of the sequence. Taking the sequence length and the TBS as examples, which each have four possible values, there is a first correspondence between the sequence length and the TBS. Optionally, when the sequence length is a first length, it corresponds to a first value of TBS; when the sequence length is a second length, it corresponds to a second value of TBS; when the sequence length is a third length, it corresponds to a third value of TBS; and when the sequence length is a fourth length, it corresponds to a fourth value of TBS. The first correspondence between the sequence length and TBS is determined based on protocol predefined information or network configuration information.

[0399] The length of the above sequence is determined based on the frequency domain resource size corresponding to the second transmission resource. For example, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 4, for example, the third length corresponds to the largest prime number less than N / 4 or the third length is equal to N / 4; the fourth length is determined based on N / 8, for example, the fourth length corresponds to the largest prime number less than N / 8 or the fourth length is equal to N / 8. Alternatively, the first length is determined based on the frequency domain resource size N, for example, the first length corresponds to the largest prime number less than N or the first length is equal to N; the second length is determined based on N / 2, for example, the second length corresponds to the largest prime number less than N / 2 or the second length is equal to N / 2; the third length is determined based on N / 3, for example, the third length corresponds to the largest prime number less than N / 3 or the third length is equal to N / 3; the fourth length is determined based on N / 4, for example, the fourth length corresponds to the largest prime number less than N / 4 or the fourth length is equal to N / 4. The first, second, third, and fourth values ​​of TBS mentioned above are not exactly the same or are all different, and this application does not limit them.

[0400] It should be noted that Table 14 above is merely an exemplary illustration of the first correspondence between sequence length and TBS value, and the method implemented in this application is not limited to the correspondence in Table 14. 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 sequence lengths, and the corresponding TBS values ​​are also K, where K is an integer greater than or equal to 1.

[0401] The mapping method of the sequence carrying the first indication information on the first transmission resource:

[0402] In some embodiments, the mapping method of sequence to first transmission resource includes a mapping method with or without frequency domain offset.

[0403] In some embodiments, a frequency domain unit includes at least one of bandwidth, carrier, physical resource block (PRB), bandwidth portion (BWP), subband, subchannel, subcarrier, and units based on other frequency domain units. Of course, frequency domain units are not limited to those listed above, and units defined in future communication protocols also apply to this application.

[0404] In some embodiments, the length of the sequence carrying the first indication information is L1, and the number of frequency domain units corresponding to the first transmission resource is L2, wherein the length of the sequence is not greater than the number of frequency domain units corresponding to the first transmission resource, that is, L1 is less than or equal to L2. Optionally, the sequence carrying the first indication information can be mapped onto the first transmission resource according to different mapping methods.

[0405] In some embodiments, the length L1 of the sequence is determined based on the number of frequency domain units L2. Here, L1 is the largest prime number less than L2, or L1 is equal to L2.

[0406] In some embodiments, the length L1 of the sequence is determined based on L2 / A, where parameter A is an integer greater than or equal to 1.

[0407] The sequence length L1 is determined based on the number of frequency domain units L2.

[0408] Mapping Method 1: Map the sequence on the first transmission resource in ascending order of frequency domain resources.

[0409] In some embodiments, sequences are mapped on the first transmission resource in ascending order of frequency domain resources, or in descending order of frequency domain resources. Optionally, if the length L1 of the sequence is less than the number of frequency domain units L2 corresponding to the first transmission resource, some frequency domain resources will not have mapped sequences. Here, L1 and L2 are positive integers, and L1 is less than or equal to L2.

[0410] Referring to Figure 9, the following example illustrates the process, where the number of frequency domain units L2 corresponding to the first transmission resource is 36 and the sequence length L1 is 31. The sequence length L1 is the largest prime number less than the number of frequency domain units L2. As shown in Figure 9(a), mapping begins from the lowest frequency domain position, and the sequence is mapped on the first transmission resource in ascending order of frequency domain resources. The sequence includes 31 data points, which are sequentially mapped onto 36 frequency domain units, with one data point mapped onto each frequency domain unit. There are 5 frequency domain resources without a mapped sequence.

[0411] In some embodiments, the sequence is mapped on the first transmission resource in ascending order of frequency domain resources. The first (L2-L1) data of the sequence are also mapped to the (L2-L1) frequency domain units with the highest frequency domain position of the first transmission resource. Alternatively, the first (L2-L1) data of the sequence are mapped to the remaining (L2-L1) frequency domain units.

[0412] In some embodiments, the sequence is mapped on the first transmission resource in descending order of frequency domain resources. The first (L2-L1) data of the sequence are also mapped to the (L2-L1) frequency domain units with the lowest frequency domain position of the first transmission resource. Alternatively, the first (L2-L1) data of the sequence are mapped to the remaining (L2-L1) frequency domain units.

[0413] Referring to Figure 9, the following example illustrates the process with the number of frequency domain units L2 corresponding to the first transmission resource being 36 and the sequence length L1 being 31. As shown in Figure 9(b), mapping begins from the lowest frequency domain position, and the sequence is mapped on the first transmission resource in ascending order of frequency domain resources. The 31 data points are sequentially mapped onto 36 frequency domain units, with the first 5 data points of the sequence mapped onto the 5 frequency domain units with the highest frequency domain positions on the first transmission resource.

[0414] Mapping Method 2: Map the sequence on the first transmission resource from the frequency domain position indicated by the reference point.

[0415] In some embodiments, a sequence is mapped onto a first transmission resource from a frequency domain location indicated by a reference point.

[0416] Optionally, a sequence is mapped onto the first transmission resource from a first frequency domain position indicated by a reference point. The first frequency domain position includes one of the following: the lowest frequency domain position of the first transmission resource; the highest frequency domain position of the first transmission resource; the frequency domain position corresponding to the floor value or floor value of the first difference; where the first difference is the difference between the number of frequency domain units corresponding to the first transmission resource and the length of the sequence. The frequency domain position corresponding to the floor value or floor value of the first difference corresponds to the frequency domain position of floor((L2-L1) / 2) or ceil((L2-L1) / 2). Here, floor() represents the floor operation, and ceil() represents the floor operation.

[0417] Referring to Figure 9, taking the example of the number of frequency domain units L2 corresponding to the first transmission resource being 36 and the sequence length L1 being 31, as shown in Figures (a) and (b) of Figure 9, the reference point position is the lowest frequency domain position of the first transmission resource.

[0418] Referring to Figure 9, taking the example of the number of frequency domain units L2 corresponding to the first transmission resource being 36 and the sequence length L1 being 31, as shown in Figure 9(c), the difference between the number of frequency domain units corresponding to the first transmission resource and the sequence length is 5, the reference point position is 3, and the two frequency domain units at the lowest frequency position and the three frequency domain units at the highest position do not map the sequence.

[0419] Referring to Figure 9, taking the example of the number of frequency domain units L2 corresponding to the first transmission resource being 36 and the sequence length L1 being 31, as shown in Figure 9(d), the difference between the number of frequency domain units corresponding to the first transmission resource and the sequence length is 5, the first frequency domain offset is 3, and the 3 frequency domain units at the lowest frequency domain position and the 2 frequency domain units at the highest position do not map the sequence.

[0420] The length L1 of the sequence is determined based on L2 and A.

[0421] In some embodiments, the length L1 of the sequence is determined based on the number of frequency domain units L2 corresponding to the first transmission resource and parameter A. Parameter A is the interval between two adjacent frequency domain units in the subset of the first transmission resource. Parameter A is an integer greater than or equal to 1. Optionally, the value of parameter A includes one of {2, 3, 4, 6, 12}.

[0422] Mapping Method 3: Map the sequence to different frequency domain units of the first transmission resource subset.

[0423] In some embodiments, when the length of the sequence is determined based on the number of frequency domain units corresponding to the first transmission resource and parameter A, the sequence is mapped to different frequency domain units of the first transmission resource subset. The first transmission resource subset is a resource set consisting of some transmission resources in the first transmission resource. The first transmission resource subset includes n frequency domain units, and the interval between two adjacent frequency domain units in the first transmission resource subset is parameter A.

[0424] In some embodiments, the first transmission resource subset may be referred to as the first comb-shaped resource subset, wherein the n frequency domain units in the first transmission resource subset are arranged in a comb-like pattern. Mapping method three may also be referred to as a mapping method using comb teeth.

[0425] In some embodiments, the first subset of transmission resources refers to a subset of the first transmission resources, consisting of a portion of the transmission resources (e.g., frequency domain units). Optionally, the first subset of transmission resources contains n frequency domain units. The spacing between any two adjacent units in the first transmission resource is determined by parameter A, where n is determined based on the quotient of the number of frequency domain units corresponding to the first transmission resource and parameter A. One frequency domain unit from each set of A frequency domain units is used to map the sequence, and the value of parameter A includes one of {2, 3, 4, 6, 12}.

[0426] Referring to Figure 10, the following example illustrates the situation with the first transmission resource having 36 frequency domain units (L2), a parameter A of 2, and a sequence length (L1) of 17. The first transmission resource can include two subsets, each containing 18 frequency domain units. As shown in Figure 10(a), with parameter A of 2, the first transmission resource can include two subsets. The frequency domain offset of the first subset is 0, and the frequency domain offset of the second subset is 1. The interval between two adjacent frequency domain units in the first subset is 2. Mapping the sequence to the first subset results in a frequency domain offset of 0. As shown in Figure 10(b), with parameter A of 2, the first transmission resource can include two subsets. The frequency domain offset of the first subset is 0, and the frequency domain offset of the second subset is 1. The interval between two adjacent frequency domain units in the first transmission resource subset is 2. The sequence is mapped to the second first transmission resource subset, and the frequency domain offset of the sequence mapping is 1.

[0427] In some embodiments, mapping method three and mapping method one can be combined. When mapping a sequence to the first transmission resource subset, the sequence is mapped on the first transmission resource subset in ascending order of frequency domain resources. The first (L2 / A-L1) data of the sequence are also mapped to the (L2 / A-L1) frequency domain units with the highest frequency domain position in the first transmission resource subset. In some embodiments, when mapping a sequence to the first transmission resource subset, the sequence is mapped on the first transmission resource subset in descending order of frequency domain resources. The first (L2 / A-L1) data of the sequence are also mapped to the (L2 / A-L1) frequency domain units with the lowest frequency domain position in the first transmission resource subset.

[0428] Referring to Figure 10, taking an example where the number of frequency domain units L2 corresponding to the first transmission resource is 36, parameter A is 2, and the sequence length L1 is 17, as shown in Figure 10(c), parameter A is 2. The first transmission resource can include two subsets of the first transmission resource. The frequency domain offset of the first subset is 0, and the frequency domain offset of the second subset is 1. The interval between two adjacent frequency domain units in the first subset is 2. One frequency domain unit in every two frequency domain units is used to map the sequence to the first subset of the first transmission resource. The frequency domain offset of the sequence mapping is 0. One frequency domain unit at the high-frequency position in the first subset of the first transmission resource is not mapped. The first bit of the sequence (the first frequency domain unit in the first subset of the first transmission resource) is mapped to the one frequency domain unit at the high-frequency position in the first subset of the first transmission resource. As shown in Figure 10(d), parameter A is 2. The first transmission resource can include two subsets of the first transmission resource. The frequency domain offset of the first subset is 0, and the frequency domain offset of the second subset is 1. The interval between two adjacent frequency domain units in the first subset is 2. One frequency domain unit in every two frequency domain units is used to map the sequence to the second subset of the first transmission resource. The frequency domain offset of the sequence mapping is 1. One frequency domain unit at the high-frequency position in the second subset of the first transmission resource is not mapped. The first bit of the sequence (the first frequency domain unit in the second subset of the first transmission resource) is mapped to one frequency domain unit at the high-frequency position in the second subset of the first transmission resource.

[0429] Mapping Method 4: Map the sequence to different frequency domain units of the second transmission resource subset.

[0430] In some embodiments, when the length of the sequence is determined based on the number of frequency domain units corresponding to the first transmission resource and parameter A, the sequence is mapped to different frequency domain units of the second transmission resource subset. The second transmission resource subset is a resource set consisting of a portion of the transmission resources in the first transmission resource. The second transmission resource subset includes n frequency domain units and includes n consecutive frequency domain units of the first transmission resource.

[0431] In some embodiments, the second subset of transmission resources refers to a continuous portion of the first transmission resource, which contains n consecutive frequency domain units. Alternatively, the second subset of transmission resources can be understood as a set of n consecutive frequency domain units in the first transmission resource. Optionally, the n consecutive frequency domain units of the first transmission resource are determined based on parameter A. The n consecutive frequency domain units are (L2 / A) frequency domain units, and each (L2 / A) consecutive frequency domain units is mapped to a sequence. The value of parameter A includes one of {2, 3, 4, 6, 12}.

[0432] Referring to Figure 10, the following example illustrates the situation with the first transmission resource having 36 frequency domain units (L2), a parameter A of 2, and a sequence length (L1) of 17. The first transmission resource can include two subsets of the second transmission resource. Each subset comprises 18 consecutive frequency domain units of the first transmission resource. The first subset includes 18 frequency domain units at low-frequency locations within the first set of transmission resources, and the second subset includes 18 frequency domain units at high-frequency locations within the first set of transmission resources. As shown in Figure 10(e), one sequence is mapped to every 18 frequency domain units. The number of frequency domain units corresponding to the first transmission resource can map to two sequences, each with a length of 17.

[0433] In some embodiments, mapping method four and mapping method one can be combined. When mapping a sequence to the second transmission resource subset, the sequence is mapped on the second transmission resource subset in ascending order of frequency domain resources. The first (L2 / A-L1) data of the sequence are also mapped to the (L2 / A-L1) frequency domain units with the highest frequency domain position in the second transmission resource subset. In some embodiments, when mapping a sequence to the second transmission resource subset, the sequence is mapped on the second transmission resource subset in descending order of frequency domain resources. The first (L2 / A-L1) data of the sequence are also mapped to the (L2 / A-L1) frequency domain units with the lowest frequency domain position in the second transmission resource subset.

[0434] Referring to Figure 10, the following example illustrates the situation with the first transmission resource having 36 frequency domain units (L2), a parameter A of 2, and a sequence length (L1) of 17. The second transmission resource subset includes 18 consecutive frequency domain units of the first transmission resource. As shown in Figure 10(f), a sequence is mapped onto every 18 frequency domain units, with a sequence length of 17. On the second transmission resource subset of the first transmission resource, the sequences are mapped in ascending order of frequency domain resources. This allows the first data element of the sequence to be mapped to a frequency domain unit located at a high-frequency position on the second transmission resource subset.

[0435] Regarding the second instruction method mentioned above:

[0436] In some embodiments, the values ​​of transmission parameters corresponding to the transmission content on the second transmission resource are indicated based on the frequency domain resource corresponding to the sequence.

[0437] Optionally, taking downlink control information or downlink control channel as an example, the value of the aggregation level corresponding to the downlink control information or downlink control channel based on the frequency domain resource indicator of the sequence; the value of the number of CCEs; and the value of the number of resources are taken as at least one of the following:

[0438] Optionally, taking downlink data as an example, the transmission content on the second transmission resource is based on at least one of the following: the value of the modulation scheme corresponding to the downlink data based on the frequency domain resource indicator corresponding to the sequence; the value of the MCS level; the value of the MCS table; and the value of the TBS.

[0439] In some embodiments, the first information associated with the first indication information includes the frequency domain resources corresponding to the sequence. The number of frequency domain resources available for transmitting the sequence is B1, and the transmission parameters have B2 possible values. There is a second correspondence between the frequency domain resources corresponding to the sequence and the values ​​of the transmission parameters. Optionally, the second 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.

[0440] In some embodiments, B1 frequency domain resources available for transmitting sequences correspond to different frequency domain portions of the first transmission resource; or, B1 frequency domain resources available for transmitting sequences correspond to B1 first transmission resources, and the B1 first transmission resources are associated with the same second transmission resource.

[0441] 1. The sub-frequency domain of the first transmission resource is used to indicate the transmission parameters indicated by the first indication information.

[0442] In some embodiments, the different values ​​of transmission parameters corresponding to different sub-frequency domains of the first transmission resource can also be understood as the different values ​​of transmission parameters corresponding to different sub-frequency domains of the first transmission resource, that is, the values ​​of transmission parameters are determined based on the sub-frequency domains of the first transmission resource.

[0443] In some embodiments, the network device configures a first transmission resource and a second transmission resource with an association relationship. The first transmission resource includes multiple frequency domain resources that can be used to transmit first indication information. Optionally, the frequency domain resources of the first transmission resource are divided into multiple different frequency domain portions, each frequency domain portion being called a sub-frequency domain (or sub-frequency domain resource), and each sub-frequency domain is used to transmit (indicate) different values ​​of transmission parameters or the same values ​​of transmission parameters. Optionally, frequency domain resources that can be used to transmit sequences carrying the first indication information are corresponding to different frequency domain portions of the first transmission resource.

[0444] For example, referring to Figure 11, as shown in Figure 11(a), the frequency domain resources of the first transmission resource are divided into four different frequency domain parts, each of which is called a sub-frequency domain (or sub-frequency domain resource). The network device can transmit first indication information in each sub-frequency domain to indicate the values ​​of the transmission parameters corresponding to the transmission content on the second transmission resource. That is, the network device can configure the values ​​of the transmission parameters indicated by the first indication information transmitted in each sub-frequency domain. The second correspondence between the network device's configured frequency domain range index and the values ​​of the transmission parameters indicated by the first indication information is shown in Table 15 below.

[0445] Table 15

[0446] The frequency domain range index represents the sub-frequency domain range index within the frequency domain range corresponding to the first transmission resource. As shown in Figure 11(a), the first transmission resource is divided into four sub-frequency domains, and the sub-frequency domain range indices corresponding to the four sub-frequency domains are "0", "1", "2", and "3", respectively. The transmission parameters indicated by the first indication information are the transmission parameters corresponding to the transmission content on the second transmission resource. The transmission parameters may include at least one of the following: downlink control information or the aggregation level corresponding to the downlink control channel; the number of CCEs; the number of resources; the modulation scheme corresponding to the downlink data; the MCS level; the MCS table; and the TBS.

[0447] For example, the transmission parameters correspond to the number of CCEs in the downlink control channel. When the sub-frequency domain range index of the first transmission resource is "0", it means that the number of CCEs is 16; when the sub-frequency domain range index of the first transmission resource is "1", it means that the number of CCEs is 8; when the sub-frequency domain range index of the first transmission resource is "2", it means that the number of CCEs is 4; and when the sub-frequency domain range index of the first transmission resource is "3", it means that the number of CCEs is 2.

[0448] For example, the transmission parameters correspond to the modulation scheme of the downlink data. When the sub-frequency domain range index of the first transmission resource is "0", it indicates that the modulation scheme is QPSK (or Qm = 2); when the sub-frequency domain range index of the first transmission resource is "1", it indicates that the modulation scheme is 64QAM (or Qm = 6); when the sub-frequency domain range index of the first transmission resource is "2", it indicates that the modulation scheme is 256 (or Qm = 8); when the sub-frequency domain range index of the first transmission resource is "3", it indicates that the modulation scheme is 1024QAM (or Qm = 10).

[0449] For example, the transmission parameters correspond to the MCS table for downlink data. When the sub-frequency range index of the first transmission resource is "0", it indicates that the MCS table supports a maximum of 64QAM; when the sub-frequency range index of the first transmission resource is "1", it indicates that the MCS table supports a maximum of 256QAM; when the sub-frequency range index of the first transmission resource is "2", it indicates that the MCS table supports a maximum of 1024QAM; and when the sub-frequency range index of the first transmission resource is "3", it indicates that the MCS table supports low spectral efficiency.

[0450] It should be noted that Table 15 above is merely an exemplary illustration of the second correspondence between the frequency domain range index and the values ​​of the transmission parameters indicated by the first indication information. The method implemented in this application is not limited to the correspondence in Table 15. In some embodiments, the correspondence of network configuration only includes a portion of the contents of the table above, such as only any two rows in the table above; in some embodiments, the correspondence of network configuration includes K frequency domain range indices, and the corresponding values ​​of the transmission parameters indicated by the first indication information are also K, where K is an integer greater than or equal to 1.

[0451] It should be noted that the first, second, third, and fourth values ​​in Table 15 above are not exactly the same or are all different, but this application does not limit this.

[0452] 2. Multiple first transmission resources are used to indicate the transmission parameters indicated by the first indication information.

[0453] In some embodiments, the different values ​​of transmission parameters corresponding to different first transmission resources can also be understood as the different values ​​of transmission parameters corresponding to different first transmission resources, that is, the values ​​of transmission parameters are determined based on the resource index corresponding to the first transmission resource.

[0454] In some embodiments, the network device configures a first transmission resource and a second transmission resource with an association relationship. The first transmission resource includes multiple frequency domain resources that can be used to transmit first indication information. Optionally, the network device can configure multiple first transmission resources to be associated with the same second transmission resource, and each first transmission resource can be used to transmit the first indication information. The first indication information transmitted using different first transmission resources is used to indicate different or identical values ​​of transmission parameters. Optionally, frequency domain resources available for transmitting sequences can be mapped to multiple first transmission resources.

[0455] For example, as shown in Figure 11(b), the network device is configured with four first transmission resources. The network device can transmit first indication information on each first transmission resource to indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource. The second correspondence between the network device's configured first transmission resource index and the value of the transmission parameter indicated by the first indication information is shown in Table 16 below.

[0456] Table 16

[0457] Here, the first transmission resource index represents a different first transmission resource index among multiple first transmission resources configured by the network device. As shown in Figure 11(b), the network device is configured with four first transmission resources, and the first transmission resource indices corresponding to the four first transmission resources are "0", "1", "2", and "3", respectively. The transmission parameters indicated by the first indication information are the transmission parameters corresponding to the transmission content on the second transmission resource. The transmission parameters may include at least one of the following: downlink control information or the aggregation level corresponding to the downlink control channel; number of CCEs; number of resources; modulation scheme corresponding to the downlink data; MCS level; MCS table; and TBS.

[0458] For example, the transmission parameters correspond to the number of CCEs in the downlink control channel. When the first transmission resource index is "0", it means that the number of CCEs in the downlink control channel indicated by the first indication information is 16; when the first transmission resource index is "1", it means that the number of CCEs is 8; when the sub-frequency domain range index of the first transmission resource is "2", it means that the number of CCEs is 4; when the sub-frequency domain range index of the first transmission resource is "3", it means that the number of CCEs is 2.

[0459] For example, the transmission parameters correspond to the modulation scheme of the downlink data. When the first transmission resource index is "0", it indicates that the modulation scheme is QPSK (or Qm = 2); when the first transmission resource index is "1", it indicates that the modulation scheme is 64QAM (or Qm = 6); when the first transmission resource index is "2", it indicates that the modulation scheme is 256 (or Qm = 8); when the first transmission resource index is "3", it indicates that the modulation scheme is 1024QAM (or Qm = 10).

[0460] For example, the transmission parameters correspond to the MCS table for downlink data. When the first transmission resource index is "0", it indicates that the MCS table supports a maximum of 64QAM; when the first transmission resource index is "1", it indicates that the MCS table supports a maximum of 256QAM; when the first transmission resource index is "2", it indicates that the MCS table supports a maximum of 1024QAM; and when the first transmission resource index is "3", it indicates that the MCS table supports low spectral efficiency.

[0461] It should be noted that Table 16 above is merely an exemplary illustration of the second correspondence between the first transmission resource index and the values ​​of the transmission parameters indicated by the first indication information. The method implemented in this application is not limited to the correspondence in Table 16. In some embodiments, the correspondence of network configuration only includes a portion of the contents of the table above, such as only any two rows in the table above; in some embodiments, the correspondence of network configuration includes K first transmission resource indices, and the corresponding values ​​of the transmission parameters indicated by the first indication information are also K, where K is an integer greater than or equal to 1.

[0462] It should be noted that the first, second, third, and fourth values ​​in Table 16 above are not exactly the same or are all different, but this application does not limit this.

[0463] 3. The frequency domain offset is used to indicate the value of the transmission parameter indicated by the first indication information.

[0464] In some embodiments, different frequency domain offsets correspond to different values ​​of transmission parameters. This can also be understood as different frequency domain offsets corresponding to different values ​​of transmission parameters, i.e., the values ​​of transmission parameters are determined based on the frequency domain offsets.

[0465] In some embodiments, the sequence is mapped onto the third subset of transmission resources using a comb-like method (mapping method three). The number of frequency domain resources available for transmitting the sequence is B1, and the B1 available frequency domain resources correspond to different frequency domain offsets. The third subset of transmission resources corresponds to one of the B1 available frequency domain resources for transmitting the sequence.

[0466] In some embodiments, each third subset of transmission resources can be considered as a comb-shaped frequency domain resource; or, each third subset of transmission resources can be considered as a set of frequency domain resources arranged in a comb-like pattern. Optionally, each third subset of transmission resources can be considered as a set of equally spaced frequency domain resources. For example, each third subset of transmission resources includes 1 / 4 of the frequency domain resources in the first transmission resources, and the interval between two adjacent frequency domain resources in each third subset of transmission resources is 4 frequency domain units.

[0467] For example, referring to Figure 12, the first transmission resource has 36 frequency domain units, parameter A is 4, and the sequence length is 9. The third transmission resource subset includes 9 frequency domain units. As shown in Figure 12(a), parameter A is 4, meaning the interval between two adjacent frequency domain units in the third transmission resource subset is 4. One frequency domain unit out of every 4 is used to map the sequence to the first frequency domain unit in the third transmission resource subset, and the frequency domain offset of the sequence mapping is 0.

[0468] As shown in Figure 12(b), parameter A is 4, that is, the interval between two adjacent frequency domain units in the third transmission resource subset is 4. One frequency domain unit in every 4 frequency domain units is used to map the sequence to the second frequency domain unit in the third transmission resource subset. The frequency domain offset of the sequence mapping is 1.

[0469] As shown in Figure 12(c), parameter A is 4, that is, the interval between two adjacent frequency domain units in the third transmission resource subset is 4. One frequency domain unit in every 4 frequency domain units is used to map the sequence to the third frequency domain unit in the third transmission resource subset. The frequency domain offset of the sequence mapping is 2.

[0470] As shown in Figure 12(d), parameter A is 4, that is, the interval between two adjacent frequency domain units in the third transmission resource subset is 4. One frequency domain unit in every 4 frequency domain units is used to map the sequence to the fourth frequency domain unit in the third transmission resource subset. The frequency domain offset of the sequence mapping is 3.

[0471] In some embodiments, B1 frequency domain resources available for transmitting sequences correspond to different frequency domain offsets, and different frequency domain offsets correspond to different first indication information. The first indication information is used to indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource. That is, each frequency domain offset corresponds to a different value of the transmission parameter indicated by the first indication information. The terminal device detects the first indication information on the first transmission resource for different frequency domain offsets. If a sequence carrying the first indication information is detected based on a certain frequency domain offset, the transmission parameters of the first indication information it carries can be determined according to the second correspondence between the frequency domain offset and the value of the transmission parameter indicated by the first indication information. The second correspondence between the network configuration frequency domain offset and the value of the transmission parameter indicated by the first indication information is shown in Table 17 below.

[0472] Table 17

[0473] The frequency domain offset is the frequency domain offset when the sequence is mapped onto the third subset of the first transmission resource using a comb-like method. The transmission parameters indicated by the first indication information are the transmission parameters corresponding to the transmission content on the second transmission resource. The transmission parameters may include at least one of the following: downlink control information or the aggregation level corresponding to the downlink control channel; number of CCEs; number of resources; modulation scheme corresponding to the downlink data; MCS level; MCS table; and TBS.

[0474] For example, the transmission parameters correspond to the number of CCEs in the downlink control channel. When the frequency domain offset is 0, it means that there are 16 CCEs; when the frequency domain offset is 1, it means that there are 8 CCEs; when the frequency domain offset is 1, it means that there are 4 CCEs; and when the frequency domain offset is 1, it means that there are 2 CCEs.

[0475] For example, the transmission parameters correspond to the modulation scheme of the downlink data. When the frequency domain offset is 0, it indicates that the modulation scheme is QPSK (or Qm = 2); when the frequency domain offset is 1, it indicates that the modulation scheme is 64QAM (or Qm = 6); when the frequency domain offset is 2, it indicates that the modulation scheme is 256 (or Qm = 8); when the frequency domain offset is 3, it indicates that the modulation scheme is 1024QAM (or Qm = 10).

[0476] For example, the transmission parameters correspond to the MCS table for downlink data. When the frequency domain offset is 0, it means that the MCS table supports a maximum of 64QAM; when the frequency domain offset is 1, it means that the MCS table supports a maximum of 256QAM; when the frequency domain offset is 2, it means that the MCS table supports a maximum of 1024QAM; and when the frequency domain offset is 3, it means that the MCS table with low spectral efficiency is supported.

[0477] It should be noted that Table 17 above is merely an exemplary illustration of the second correspondence between the frequency domain offset and the values ​​of the transmission parameters indicated by the first indication information. The method implemented in this application is not limited to the correspondence in Table 17. In some embodiments, the correspondence of network configuration only includes a portion of the contents of the table above, such as only any two rows in the table above; in some embodiments, the correspondence of network configuration includes K frequency domain offsets, and the corresponding values ​​of the transmission parameters indicated by the first indication information are also K, where K is an integer greater than or equal to 1.

[0478] It should be noted that the first, second, third, and fourth values ​​in Table 17 above are not exactly the same or are all different, but this application does not limit this.

[0479] In some embodiments, different frequency domain resources indicate different aggregation levels; or, different frequency domain resources indicate different CCE numbers; or, different frequency domain resources indicate different resource numbers; or, different frequency domain resources indicate different modulation schemes; or, different frequency domain resources indicate different MCS tables; or, different frequency domain resources indicate different MCS levels; or, different frequency domain resources indicate different TBS. For details, please refer to the specific content of "Regarding the above indication method one" above, which will not be repeated here.

[0480] In some embodiments, the mapping method for the sequence carrying the first indication information to the frequency domain can also be any one of mapping method one, mapping method two, mapping method three and mapping method four, or a combination of different mapping methods, such as mapping method three and mapping method one. For details on the mapping methods, please refer to the four mapping methods mentioned above, which will not be repeated here.

[0481] Regarding the above-mentioned instruction method three:

[0482] In some embodiments, the values ​​of transmission parameters corresponding to the transmission content on the second transmission resource are indicated based on the temporal resource corresponding to the sequence.

[0483] Optionally, taking downlink control information or downlink control channel as an example, the value of the aggregation level corresponding to the downlink control information or downlink control channel, the value of the number of CCEs, and the value of the number of resources are taken based on the time-domain resource indicator corresponding to the sequence.

[0484] Optionally, taking downlink data as an example, the transmission content on the second transmission resource is indicated by at least one of the following: the value of the modulation scheme corresponding to the downlink data based on the time domain resource corresponding to the sequence; the value of the MCS level; the value of the MCS table; and the value of the TBS.

[0485] In some embodiments, the first information associated with the first indication information includes the time-domain resources corresponding to the sequence. The number of time-domain resources available for transmitting the sequence is C1, and the transmission parameters have C2 possible values. There is a third correspondence between the time-domain resources corresponding to the sequence and the values ​​of the transmission parameters. Optionally, the third 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.

[0486] In some embodiments, time-domain resources include time slots or time-domain symbols. Optionally, the granularity of time-domain resource partitioning may also include at least one of frames, subframes, mini-time slots, sub-time slots, symbols, symbol groups, and units based on other time-domain units. This application uses OFDM symbols as an example to illustrate the granularity of time-domain resource partitioning. An OFDM symbol can be understood as a time-domain unit with a certain time-domain length. Optionally, the time-domain length of an OFDM symbol is related to the subcarrier spacing; for example, the larger the subcarrier spacing, the shorter the time-domain length of an OFDM symbol.

[0487] The first transmission resource includes multiple OFDM symbols that can be used to transmit the first indication information. The network device is configured with a correspondence between the symbol information of the OFDM symbols used to transmit the first indication information and the first indication information. Optionally, the OFDM symbols are described using the granularity of time-domain resource division, and there is a one-to-many correspondence between the OFDM symbols and the values ​​of the transmission parameters indicated by the first indication information; or, there is a one-to-one correspondence between the OFDM symbols and the values ​​of the transmission parameters indicated by the first indication information.

[0488] Time-domain resources are used to indicate the values ​​of the transmission parameters indicated by the first indication information.

[0489] In some embodiments, different values ​​of transmission parameters corresponding to different time-domain resources can also be understood as different values ​​of transmission parameters corresponding to different time-domain resources, that is, determining the value of transmission parameters based on time-domain resources.

[0490] In some embodiments, time-domain resources include OFDM symbols or time slots.

[0491] In some embodiments, the network device is configured with an associated first transmission resource and a second transmission resource. The first transmission resource includes a plurality of OFDM symbols that can be used to transmit first indication information. The first information associated with the first indication information is used to indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource.

[0492] For example, referring to Figure 13, as shown in Figure 13(a), the time domain resources of the first transmission resource include two OFDM symbols, each of which can be used to transmit the first indication information. The third correspondence between the network device configuration OFDM symbol index and the values ​​of the transmission parameters indicated by the first indication information is shown in Table 18 below.

[0493] Table 18

[0494] The OFDM symbol index represents the index of OFDM symbols within the first transmission resource range, used to identify and distinguish the numbers or identifiers of different OFDM symbols. The transmission parameters indicated by the first indication information are the transmission parameters corresponding to the transmission content on the second transmission resource. The transmission parameters may include at least one of the following: downlink control information or the aggregation level corresponding to the downlink control channel; number of CCEs; number of resources; modulation scheme corresponding to the downlink data; MCS level; MCS table; and TBS.

[0495] For example, the transmission parameters correspond to the number of CCEs in the downlink control channel. When the OFDM symbol index is "0", it means that the number of CCEs is 16; when the OFDM symbol index is "1", it means that the number of CCEs is 8.

[0496] For example, the transmission parameters correspond to the modulation scheme of the downlink data. When the OFDM symbol index is "0", it means that the modulation scheme is QPSK (or Qm=2); when the OFDM symbol index is "1", it means that the modulation scheme is 64QAM (or Qm=6).

[0497] For example, the transmission parameters correspond to the MCS table for downlink data. When the OFDM symbol index is "0", it means that the maximum supported MCS table is 64QAM; when the OFDM symbol index is "1", it means that the maximum supported MCS table is 256QAM.

[0498] It should be noted that Table 18 above is merely an exemplary illustration of the third correspondence between OFDM symbol indices and the values ​​of transmission parameters indicated by the first indication information. The method implemented in this application is not limited to the correspondence in Table 18. In some embodiments, the correspondence of network configuration only includes a portion of the contents of the table above, such as only including any one row in the table above; in some embodiments, the correspondence of network configuration includes K OFDM symbol indices, and the corresponding values ​​of transmission parameters indicated by the first indication information are also K, where K is an integer greater than or equal to 1.

[0499] It should be noted that the first and second values ​​in Table 18 above are not exactly the same or are not the same, but this application does not limit this.

[0500] For example, referring to Figure 13, as shown in Figure 13(b), the time domain resources of the first transmission resource are divided into 4 OFDM symbols. Each OFDM symbol can be used to transmit the first indication information. The third correspondence between the OFDM symbol index configured by the network device and the values ​​of the transmission parameters indicated by the first indication information is shown in Table 19 below.

[0501] Table 19

[0502] The OFDM symbol index represents the index of OFDM symbols within the first transmission resource range, used to identify and distinguish the numbers or identifiers of different OFDM symbols. The transmission parameters indicated by the first indication information are the transmission parameters corresponding to the transmission content on the second transmission resource. The transmission parameters may include at least one of the following: downlink control information or the aggregation level corresponding to the downlink control channel; number of CCEs; number of resources; modulation scheme corresponding to the downlink data; MCS level; MCS table; and TBS.

[0503] For example, the transmission parameters correspond to the number of CCEs in the downlink control channel. When the OFDM symbol index is "0", it means that the number of CCEs is 16; when the OFDM symbol index is "1", it means that the number of CCEs is 8; when the OFDM symbol index is "2", it means that the number of CCEs is 4; and when the OFDM symbol index is "3", it means that the number of CCEs is 2.

[0504] For example, the transmission parameters correspond to the modulation scheme of the downlink data. When the OFDM symbol index is "0", it indicates that the modulation scheme is QPSK (or Qm = 2); when the OFDM symbol index is "1", it indicates that the modulation scheme is 64QAM (or Qm = 6); when the OFDM symbol index is "2", it indicates that the modulation scheme is 256 (or Qm = 8); when the OFDM symbol index is "3", it indicates that the modulation scheme is 1024QAM (or Qm = 10).

[0505] For example, the transmission parameters correspond to the MCS table for downlink data. When the OFDM symbol index is "0", it indicates that the MCS table supports a maximum of 64QAM; when the OFDM symbol index is "1", it indicates that the MCS table supports a maximum of 256QAM; when the OFDM symbol index is "2", it indicates that the MCS table supports a maximum of 1024QAM; and when the OFDM symbol index is "3", it indicates that the MCS table supports low spectral efficiency.

[0506] It should be noted that Table 19 above is merely an exemplary illustration of the third correspondence between OFDM symbol indices and the values ​​of transmission parameters indicated by the first indication information. The method implemented in this application is not limited to the correspondence in Table 19. In some embodiments, the correspondence of network configuration only includes a portion of the contents of the table above, such as only any two rows in the table above; in some embodiments, the correspondence of network configuration includes K OFDM symbol indices, and the corresponding values ​​of transmission parameters indicated by the first indication information are also K, where K is an integer greater than or equal to 1.

[0507] It should be noted that the first, second, third, and fourth values ​​in Table 19 above are not exactly the same or are all different, but this application does not limit this.

[0508] In some embodiments, different time-domain resources indicate different aggregation levels; or, different time-domain resources indicate different CCE numbers; or, different time-domain resources indicate different resource numbers; or, different time-domain resources indicate different modulation schemes; or, different time-domain resources indicate different MCS tables; or, different time-domain resources indicate different MCS levels; or, different time-domain resources indicate different TBS. For details, please refer to the specific content of "Regarding the above indication method one" above, which will not be repeated here.

[0509] In some embodiments, the mapping method for the sequence carrying the first indication information to the frequency domain can also be any one of mapping method one, mapping method two, mapping method three and mapping method four, or a combination of different mapping methods, such as mapping method three and mapping method one. For details on the mapping methods, please refer to the four mapping methods mentioned above, which will not be repeated here.

[0510] Regarding the above-mentioned instruction method four:

[0511] In some embodiments, the sequence index corresponding to the sequence indicates the value of the transmission parameter corresponding to the transmission content on the second transmission resource.

[0512] Optionally, taking downlink control information or downlink control channel as an example, the value of the aggregation level corresponding to the downlink control information or downlink control channel is indicated by the sequence index corresponding to the sequence; the value of the number of CCEs; and the value of the number of resources.

[0513] Optionally, taking downlink data as an example of the transmission content on the second transmission resource, the value of the modulation scheme corresponding to the downlink data is indicated by the sequence index corresponding to the sequence; the value of the MCS level; the value of the MCS table; and the value of the TBS.

[0514] In some embodiments, the first information associated with the first indication information includes the sequence index corresponding to the sequence. The sequence index corresponding to the sequence includes D1 values, and the transmission parameter values ​​include D2 values. There is a fourth correspondence between the sequence index corresponding to the sequence and the transmission parameter values, which 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.

[0515] In some embodiments, a sequence index is an identifier for a sequence, and the sequence index is an index number used to uniquely identify and select the sequence. Optionally, the first indication information is carried by multiple sequences, that is, the first indication information is indicated by multiple sequences jointly. The sequence index is an identifier for multiple sequences.

[0516] For example, the first part of the first indication information is carried by all the bits of the first sequence, or the first part of the first indication information is carried by some bits of the first sequence; the second part of the first indication information is carried by all the bits of the second sequence, or the second part of the first indication information is carried by some bits of the second sequence.

[0517] In some embodiments, the network device is configured with associated first transmission resources and second transmission resources, wherein the first indication information transmitted on the first transmission resource may include multiple sequences, and the sequence for carrying the first indication information is determined by a first parameter, which includes at least one of the following:

[0518] • Parameters used to determine the initial values ​​of the pseudo-random sequence generator;

[0519] • Parameters used to determine the cyclic shift value;

[0520] • Parameters used to determine the base sequence number.

[0521] The parameter of the pseudo-random sequence generator initial value is used to determine the initial value of the sequence; different initial values ​​will produce different sequences.

[0522] In some embodiments, the sequence used to carry the first indication information is determined by the first parameter, and the fourth correspondence between the network device configuration of the first parameter and the value of the transmission parameter indicated by the first indication information is shown in Table 20 below.

[0523] Table 20

[0524] The first parameter can take the value of at least one of the following: the initial value of the pseudo-random sequence generator, the cyclic shift value, and the base sequence number. The transmission parameters indicated by the first indication information are the transmission parameters corresponding to the transmission content on the second transmission resource. The transmission parameters may include at least one of the following: downlink control information or the aggregation level corresponding to the downlink control channel; the number of CCEs; the number of resources; the modulation scheme corresponding to the downlink data; the MCS level; the MCS table; and the TBS.

[0525] For example, the transmission parameters correspond to the number of CCEs in the downlink control channel. When the first parameter is valued as A, it means that the number of CCEs is 16; when the first parameter is valued as B, it means that the number of CCEs is 8; when the first parameter is valued as C, it means that the number of CCEs is 4; and when the first parameter is valued as D, it means that the number of CCEs is 2.

[0526] For example, the transmission parameters correspond to the modulation scheme of the downlink data. When the value of the first parameter is A, it indicates that the modulation scheme is QPSK (or Qm = 2); when the value of the first parameter is B, it indicates that the modulation scheme is 64QAM (or Qm = 6); when the value of the first parameter is C, it indicates that the modulation scheme is 256 (or Qm = 8); when the value of the first parameter is D, it indicates that the modulation scheme is 1024QAM (or Qm = 10).

[0527] For example, the transmission parameters correspond to the MCS table for downlink data. When the first parameter is valued as A, it indicates that the MCS table supports a maximum of 64QAM; when the first parameter is valued as B, it indicates that the MCS table supports a maximum of 256QAM; when the first parameter is valued as C, it indicates that the MCS table supports a maximum of 1024QAM; and when the first parameter is valued as D, it indicates that the MCS table supports low spectral efficiency.

[0528] It should be noted that Table 20 above is only an exemplary illustration of the fourth correspondence between the value of the first parameter and the value of the transmission parameter indicated by the first indication information. The method implemented in this application is not limited to the correspondence in Table 20.

[0529] It should be noted that the first, second, third, and fourth values ​​in Table 20 above are not exactly the same or are all different, but this application does not limit this.

[0530] In some embodiments, different sequence indices indicate different aggregation levels; or, different sequence indices indicate different CCE numbers; or, different sequence indices indicate different resource numbers; or, different sequence indices indicate different modulation schemes; or, different sequence indices indicate different MCS tables; or, different sequence indices indicate different MCS levels; or, different sequence indices indicate different TBSs. For details, please refer to the specific content of "Regarding the above indication method one" above, which will not be repeated here.

[0531] In some embodiments, the mapping method for the sequence carrying the first indication information to the frequency domain can also be any one of mapping method one, mapping method two, mapping method three and mapping method four, or a combination of different mapping methods, such as mapping method three and mapping method one. For details on the mapping methods, please refer to the four mapping methods mentioned above, which will not be repeated here.

[0532] Regarding the above-mentioned instruction method five:

[0533] In some embodiments, 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 sequence.

[0534] Optionally, taking downlink control information or downlink control channel as an example, the value of the aggregation level corresponding to the downlink control information or downlink control channel is indicated by the sequence group index corresponding to the sequence; the value of the number of CCEs; and the value of the number of resources.

[0535] Optionally, taking downlink data as an example, the transmission content on the second transmission resource is based on at least one of the following: the value of the modulation scheme corresponding to the downlink data indicated by the sequence group index corresponding to the sequence; the value of the MCS level; the value of the MCS table; and the value of the TBS.

[0536] In some embodiments, the first information associated with the first indication information includes the sequence group index corresponding to the sequence. The sequence group index corresponding to the sequence includes E1 values, and the transmission parameter values ​​include E2 values. There is a fifth correspondence between the sequence group index corresponding to the sequence and the transmission parameter values, which 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.

[0537] In some embodiments, a sequence group consists of one or more sequences, and a sequence group index is used to identify a sequence group, which is used to determine a set of related sequences.

[0538] In some embodiments, the network device is configured with associated first transmission resources and second transmission resources. The first indication information transmitted on the first transmission resource may include multiple sequence groups. The sequence group carrying the first indication information is determined by a first parameter, which includes at least one of the following:

[0539] • Parameters used to determine the initial values ​​of the pseudo-random sequence generator;

[0540] • Parameters used to determine the cyclic shift value;

[0541] • Parameters used to determine the group number;

[0542] • Parameters used to determine the base sequence number.

[0543] In some embodiments, the sequence group used to carry the first indication information is determined by the first parameter, and the fifth correspondence between the network device configuration of the first parameter and the value of the transmission parameter indicated by the first indication information is shown in Table 21 below.

[0544] Table 21

[0545] The first parameter can take the value of at least one of the following: the initial value of the pseudo-random sequence generator, the cyclic shift value, the group number, and the base sequence number. The transmission parameters indicated by the first indication information are the transmission parameters corresponding to the transmission content on the second transmission resource. The transmission parameters may include at least one of the following: downlink control information or the aggregation level corresponding to the downlink control channel; the number of CCEs; the number of resources; the modulation scheme corresponding to the downlink data; the MCS level; the MCS table; and the TBS.

[0546] For example, the transmission parameters correspond to the number of CCEs in the downlink control channel. When the first parameter is valued at the E-th value, it means that the number of CCEs is 16; when the first parameter is valued at the F-th value, it means that the number of CCEs is 8; when the first parameter is valued at the G-th value, it means that the number of CCEs is 4; and when the first parameter is valued at the H-th value, it means that the number of CCEs is 2.

[0547] For example, the transmission parameters correspond to the modulation scheme of the downlink data. When the value of the first parameter is E, it indicates that the modulation scheme is QPSK (or Qm = 2); when the value of the first parameter is F, it indicates that the modulation scheme is 64QAM (or Qm = 6); when the value of the first parameter is G, it indicates that the modulation scheme is 256 (or Qm = 8); when the value of the first parameter is H, it indicates that the modulation scheme is 1024QAM (or Qm = 10).

[0548] For example, the transmission parameters correspond to the MCS table for downlink data. When the first parameter is valued as E, it indicates that the MCS table supports a maximum of 64QAM; when the first parameter is valued as F, it indicates that the MCS table supports a maximum of 256QAM; when the first parameter is valued as G, it indicates that the MCS table supports a maximum of 1024QAM; and when the first parameter is valued as H, it indicates that the MCS table supports low spectral efficiency.

[0549] It should be noted that Table 21 above is only an exemplary illustration of the fifth correspondence between the value of the first parameter and the value of the transmission parameter indicated by the first indication information. The method implemented in this application is not limited to the correspondence in Table 21.

[0550] It should be noted that the first, second, third, and fourth values ​​in Table 21 above are not exactly the same or are all different, but this application does not limit this.

[0551] In some embodiments, different sequence group indexes indicate different aggregation levels; or, different sequence group indexes indicate different CCE numbers; or, different sequence group indexes indicate different resource numbers; or, different sequence group indexes indicate different modulation schemes; or, different sequence group indexes indicate different MCS tables; or, different sequence group indexes indicate different MCS levels; or, different sequence group indexes indicate different TBSs. For details, please refer to the specific content of "Regarding the above indication method one" above, which will not be repeated here.

[0552] In some embodiments, the mapping method for the sequence carrying the first indication information to the frequency domain can also be any one of mapping method one, mapping method two, mapping method three and mapping method four, or a combination of different mapping methods, such as mapping method three and mapping method one. For details on the mapping methods, please refer to the four mapping methods mentioned above, which will not be repeated here.

[0553] The following explanation uses other transmission resources, including third-party transmission resources, as an example.

[0554] Optionally, taking other transmission resources as an example, the third transmission resource is a transmission resource configured by the network device for the terminal device, and the third transmission resource is used for uplink transmission. Optionally, the third transmission resource is used to transmit feedback information and / or uplink data. The terminal device transmits at least one of the following on the third transmission resource based on the first indication information: feedback information, uplink data, uplink shared channel, and uplink data channel. The feedback information includes at least one of the following: HARQ feedback information; precoding matrix indication information; rank indication information; channel state information; channel interference information; reference signal index information; and link recovery request information.

[0555] The first indication information is used to indicate the value of the transmission parameters corresponding to the transmission content on the third transmission resource, wherein the transmission parameters include at least one of the following:

[0556] • The modulation scheme corresponding to the uplink data;

[0557] • The MCS level corresponding to the uplink data;

[0558] • The MCS table corresponding to the upstream data;

[0559] • The TBS corresponding to the uplink data.

[0560] In some embodiments, the value of the transmission parameter corresponding to the transmission content on the third transmission resource is determined based on the first information associated with the first indication information. This can be understood as determining the value of the transmission parameter indicated by the transmission content on the third transmission resource based on the first information associated with the first indication information, or it can also be understood as indicating the value of the transmission parameter corresponding to the transmission content on the third transmission resource based on the first information associated with the first indication information. Optionally, the following five different indication methods can be used to indicate the value of the transmission parameter corresponding to the transmission content on the third transmission resource.

[0561] Indication Method Six: Indicate the value of the transmission parameter corresponding to the transmission content on the third transmission resource based on the sequence length;

[0562] Indication Method 7: Based on the frequency domain resource indication of the sequence, indicate the value of the transmission parameter corresponding to the transmission content on the third transmission resource;

[0565] Indication Method 10: Based on the sequence group index corresponding to the sequence, indicate the value of the transmission parameter corresponding to the transmission content on the third transmission resource.

[0566] The five different instruction methods will be introduced below.

[0567] In some embodiments, the transmission parameters corresponding to the transmission content on the third transmission resource are indicated based on the length of the sequence; or, based on the frequency domain resources corresponding to the sequence; or, based on the sequence index or sequence group index corresponding to the sequence.

[0568] Optionally, taking the transmission content on the third transmission resource as uplink data as an example, the transmission content is based on at least one of the following: the length of the sequence; or, the frequency domain resource corresponding to the sequence; or, the time domain resource corresponding to the sequence; or, the value of the modulation scheme corresponding to the uplink data indicated by the sequence index or sequence group index corresponding to the sequence; the value of the MCS level; the value of the MCS table; or the value of the TBS.

[0569] Based on the length of the sequence, the values ​​of the transmission parameters corresponding to the transmission content on the third transmission resource are indicated. For details, please refer to the specific content of "Regarding the above indication method one" above. The implementation of indication method six is ​​the same as that of indication method one, and will not be repeated here.

[0570] The frequency domain resource indication based on the sequence indicates the value of the transmission parameter corresponding to the transmission content on the third transmission resource. For details, please refer to the specific content of "Regarding the above indication method two" in the previous text. The implementation of indication method seven is the same as the implementation of indication method two, and will not be repeated here.

[0571] The sequence-based time-domain resource indication specifies the values ​​of the transmission parameters corresponding to the transmission content on the third transmission resource. For details, please refer to the previous section "Specific content for the above indication method three". The implementation of indication method eight is the same as that of indication method three, and will not be repeated here.

[0572] The sequence index based on the sequence indicates the value of the transmission parameter corresponding to the transmission content on the third transmission resource. For details, please refer to the specific content of "Regarding the above indication method four" in the previous text. The implementation of indication method nine is the same as that of indication method four, and will not be repeated here.

[0573] The sequence group index based on the sequence indicates the value of the transmission parameter corresponding to the transmission content on the third transmission resource. For details, please refer to the specific content of "Regarding the above-mentioned indication method five" in the previous text. The implementation of indication method ten is the same as that of indication method five, and will not be repeated here.

[0574] In some embodiments, the mapping method of the sequence carrying the first indication information (the first indication information indicates the third transmission resource) to the frequency domain can be any one of mapping method one, mapping method two, mapping method three and mapping method four, or a combination of different mapping methods, such as mapping method three and mapping method one. For details on the mapping method, please refer to the four mapping methods mentioned above, which will not be repeated here.

[0575] It should be noted that the above table is merely an illustrative example, and the methods implemented in this application are not limited to the correspondences in the table. In some possible implementations, certain rows, columns, and cells in the table may form a new table, or may form a new table with other rows, columns, and cells not shown, and this application does not limit this.

[0576] The transmission content on other transmission resources is determined based on the different first information associated with the first indication information.

[0577] In some embodiments, the first indication information is carried by first information associated with the sequence, and the first information is determined based on at least one of the following: the length of the sequence; the frequency domain resources corresponding to the sequence; the time domain resources corresponding to the sequence; the sequence index corresponding to the sequence; and the sequence group index corresponding to the sequence.

[0578] For example, different lengths of a sequence correspond to different values, different states, or different sequences, thereby indicating different transmission content on other transmission resources.

[0579] For example, different frequency domain resources corresponding to a sequence may correspond to different values, different states, or different sequences, thereby indicating different transmission content on other transmission resources.

[0580] For example, different time-domain resources corresponding to a sequence may correspond to different values, different states, or different sequences, thereby indicating different transmission content on other transmission resources.

[0581] For example, different sequence groups corresponding to a sequence may correspond to different values, different states, or different sequences, thereby indicating different transmission content on other transmission resources.

[0582] In some embodiments, the transmission content on other transmission resources is determined based on different first information associated with the first indication information. This can be understood as indicating the transmission content on other transmission resources based on different first information associated with the first indication information.

[0583] In some embodiments, the other transmission resources include a second transmission resource and a third transmission resource, and the transmission content on the other transmission resources includes at least one of the following: no transmission on the second transmission resource; transmission of DCI or PDCCH on the second transmission resource; transmission of downlink data on the second transmission resource; transmission of DCI and downlink data on the second transmission resource; no transmission on the third transmission resource; transmission of feedback information on the third transmission resource; transmission of uplink data on the third transmission resource; transmission of feedback information and uplink data on the third transmission resource.

[0584] In some embodiments, the transmission content on other transmission resources is determined based on different first information associated with the first indication information.

[0585] Indication Method A: Indicates the transmission content on other transmission resources based on the length corresponding to the sequence.

[0586] Indication Method B: Indicates the transmission content on other transmission resources based on the frequency domain resources corresponding to the sequence.

[0587] Indication method C: Indicates the transmission content on other transmission resources based on the time-domain resources corresponding to the sequence.

[0588] Indication method D: Indicates the transmission content on other transmission resources based on the sequence index corresponding to the sequence.

[0589] Indication method E: Indicates the transmission content on other transmission resources based on the sequence group index corresponding to the sequence.

[0590] Regarding the above instruction method A:

[0591] There is a correlation or correspondence between sequence length and transmitted content, which is determined based on protocol predefined information or network configuration information.

[0592] In some embodiments, a first transmission resource is used to transmit first indication information, which is used to determine (or be understood as indicating) transmission content on other transmission resources. Optionally, the network device is configured with sequences of different lengths, with the length of each sequence corresponding to different transmission content.

[0593] In some embodiments, different sequence lengths correspond to different transmission contents. The transmission contents include: no transmission on the second transmission resource; transmission of DCI or PDCCH on the second transmission resource; transmission of downlink data on the second transmission resource; transmission of both DCI and downlink data on the second transmission resource; no transmission on the third transmission resource; transmission of feedback information on the third transmission resource; transmission of uplink data on the third transmission resource; and transmission of at least one of feedback information and uplink data on the third transmission resource. The relationship between different sequence lengths and different transmission contents configured in the network device is shown in Table 22.

[0594] Table 22

[0595] For example, the first information includes the length of the sequence. Taking an example where the sequence length has eight possible values, there is a correspondence between the sequence length values ​​and the transmitted content. Optionally, when the sequence length is a first length, the corresponding transmitted content is no transmission on the second transmission resource; when the sequence length is a second length, the corresponding transmitted content is DCI or PDCCH transmission on the second transmission resource; when the sequence length is a third length, the corresponding transmitted content is downlink data transmission on the second transmission resource; when the sequence length is a fourth length, the corresponding transmitted content is DCI and downlink data transmission on the second transmission resource; when the sequence length is a fifth length, the corresponding transmitted content is no transmission on the third transmission resource; when the sequence length is a sixth length, the corresponding transmitted content is feedback information transmission on the third transmission resource; when the sequence length is a seventh length, the corresponding transmitted content is uplink data transmission on the third transmission resource; and when the sequence length is an eighth length, the corresponding transmitted content is feedback information and uplink data transmission on the third transmission resource. The correspondence between the sequence length and the transmitted content is determined based on protocol predefined information or network configuration information.

[0596] It should be noted that Table 22 above is merely an illustrative example of the correspondence between sequence length and transmitted content, and does not constitute a limitation on the correspondence between sequence length and transmitted content. For example, when the sequence length is the first length, the transmitted content can be indicated as no transmission on the third transmission resource and transmission of DCI or PDCCH on the second transmission resource; as another example, when the sequence length is the second length, the transmitted content can be indicated as transmission of feedback information and uplink data on the third transmission resource.

[0597] It should be noted that the correspondence of network configurations only includes a portion of the content in the table above, such as any two rows in the table; in some implementations, the correspondence of network configurations includes a sequence length of K, and the corresponding transmission content is also K, where K is an integer greater than or equal to 1. This application does not impose any limitations on this.

[0598] Regarding instruction method B above:

[0599] There is an association or correspondence between the frequency domain resources corresponding to the sequence and the transmitted content. This association or correspondence is determined based on protocol predefined information or network configuration information.

[0600] In some embodiments, the transmission content on other transmission resources is indicated based on the frequency domain resources corresponding to the sequence.

[0601] In some embodiments, a first transmission resource is used to transmit first indication information, which is used to determine (or be understood as indicating) transmission content on other transmission resources.

[0602] In some embodiments, the frequency domain resources of the first transmission resource are divided into multiple different frequency domain parts, each frequency domain part being called a sub-frequency domain (or sub-frequency domain resource), and each sub-frequency domain is used to transmit (indicate) different transmission content. Each sub-frequency domain can be used to transmit first indication information, which is used to indicate the transmission content on other transmission resources. The correspondence between the network device configuration frequency domain range index and the transmission content indicated by the first indication information is shown in Table 23 below.

[0603] Table 23

[0604] The frequency domain range index represents the sub-frequency domain range index within the frequency domain range corresponding to the first transmission resource.

[0605] For example, the first information includes the frequency domain resources of the sequence, and the first transmission resources are divided into 8 sub-frequency domains, with the sub-frequency domain range indices corresponding to "0", "1", "2", "3", "4", "5", "6", and "7" respectively. There is a correspondence between the sub-frequency domains of the sequence and the transmission content. Optionally, when the sub-frequency domain range index of the first transmission resource is "0", the corresponding transmission content is no transmission on the second transmission resource; when the sub-frequency domain range index of the first transmission resource is "1", the corresponding transmission content is DCI or PDCCH transmission on the second transmission resource; when the sub-frequency domain range index of the first transmission resource is "2", the corresponding transmission content is downlink data transmission on the second transmission resource; when the sub-frequency domain range index of the first transmission resource is "3", the corresponding transmission content is DCI and downlink data transmission on the second transmission resource; when the sub-frequency domain range index of the first transmission resource is "4", the corresponding transmission content is no transmission on the third transmission resource; when the sub-frequency domain range index of the first transmission resource is "5", the corresponding transmission content is feedback information transmission on the third transmission resource; when the sub-frequency domain range index of the first transmission resource is "6", the corresponding transmission content is uplink data transmission on the third transmission resource; when the sub-frequency domain range index of the first transmission resource is "7", the corresponding transmission content is feedback information and uplink data transmission on the third transmission resource. The correspondence between the frequency domain range index of the first transmission resource and the transmission content is determined based on protocol predefined information or network configuration information.

[0606] It should be noted that Table 23 above is merely an illustrative example of the correspondence between frequency domain range indices and transmission content, and does not constitute a limitation on the correspondence between frequency domain range indices and transmission content. For example, when the sub-frequency domain range index of the first transmission resource is "0", the indicated transmission content may be no transmission on the third transmission resource and DCI or PDCCH transmission on the second transmission resource; as another example, when the sub-frequency domain range index of the first transmission resource is "0", the indicated transmission content may be feedback information and uplink data transmission on the third transmission resource.

[0607] It should be noted that the correspondence of network configurations only includes a portion of the content in the table above, such as any two rows in the table; in some implementations, the correspondence of network configurations includes a sequence length of K, and the corresponding transmission content is also K, where K is an integer greater than or equal to 1. This application does not impose any limitations on this.

[0608] In some embodiments, the sequence is mapped using a comb-like method (mapping method three). Frequency domain resources available for transmitting the sequence correspond to different frequency domain offsets, and different frequency domain offsets correspond to different first indication information. Optionally, different transmission content on other transmission resources is indicated according to different frequency domain offsets.

[0609] In some embodiments, the network device configures sequences of different frequency domain resources. Optionally, different transmission content on other transmission resources is indicated according to the sequences of different frequency domain resources. For details, please refer to indication method A above; this application will not elaborate further.

[0610] Regarding the above instruction method C:

[0611] There is an association or correspondence between the time-domain resources and the transmitted content corresponding to the sequence, and this association or correspondence is determined based on protocol predefined information or network configuration information.

[0612] In some embodiments, the transmission content on other transmission resources is indicated based on the time-domain resources corresponding to the sequence.

[0613] In some embodiments, time-domain resources include time slots or time-domain symbols. Optionally, the granularity of time-domain resource partitioning may also include at least one of frames, subframes, mini-slots, sub-slots, symbols, symbol groups, and units based on other time-domain units. This application uses OFDM symbols as an example to illustrate the partitioning granularity of time-domain resources. An OFDM symbol can be understood as a time-domain unit with a certain time-domain length.

[0614] In some embodiments, the first transmission resource includes a plurality of OFDM symbols that can be used to transmit first indication information. The network device configures a correspondence between the symbol information of the OFDM symbols used to transmit the first indication information and the first indication information. Optionally, different transmission content on other transmission resources is indicated according to different OFDM symbol indices. The correspondence between the OFDM symbol indices and the transmission content indicated by the first indication information configured by the network device is shown in Table 24 below.

[0615] Table 24

[0616] The OFDM symbol index represents the index of OFDM symbols within the first transmission resource range, used to identify and distinguish the numbers or identifiers of different OFDM symbols.

[0617] For example, the first information includes the time-domain resources of the sequence, and the OFDM symbol indices in the first transmission resources are "0", "1", "2", "3", "4", "5", "6", and "7", respectively. There is a correspondence between the OFDM symbol indices and the transmission content. Optionally, when the OFDM symbol index is "0", the corresponding transmission content is no transmission on the second transmission resource; when the OFDM symbol index is "1", the corresponding transmission content is DCI or PDCCH transmission on the second transmission resource; when the sub-frequency domain range index of the first transmission resource is "2", the corresponding transmission content is downlink data transmission on the second transmission resource; when the OFDM symbol index is "3", the corresponding transmission content is DCI and downlink data transmission on the second transmission resource; when the OFDM symbol index is "4", the corresponding transmission content is no transmission on the third transmission resource; when the OFDM symbol index is "5", the corresponding transmission content is feedback information transmission on the third transmission resource; when the OFDM symbol index is "6", the corresponding transmission content is uplink data transmission on the third transmission resource; when the OFDM symbol index is "7", the corresponding transmission content is feedback information and uplink data transmission on the third transmission resource. The correspondence between the frequency domain range index of the first transmission resource and the transmission content is determined based on protocol predefined information or network configuration information.

[0618] It should be noted that Table 24 above is merely an illustrative example of the correspondence between OFDM symbol indices and transmission content, and does not constitute a limitation on the correspondence between OFDM symbol indices and transmission content. For example, when the OFDM symbol index is "0", it can indicate that there is no transmission on the third transmission resource and DCI or PDCCH is transmitted on the second transmission resource; as another example, when the OFDM symbol index is "0", it can indicate that feedback information and uplink data are transmitted on the third transmission resource.

[0619] It should be noted that the correspondence of network configurations only includes a portion of the content in the table above, such as any two rows in the table; in some implementations, the correspondence of network configurations includes a sequence length of K, and the corresponding transmission content is also K, where K is an integer greater than or equal to 1. This application does not impose any limitations on this.

[0620] In some embodiments, the network device configures sequences of different time-domain resources. Optionally, different transmission content on other transmission resources is indicated according to the sequences of different time-domain resources. For details, please refer to indication method A described above; this application will not elaborate further.

[0621] Regarding the above instruction method D:

[0622] There is an association or correspondence between the sequence index corresponding to the sequence and the transmitted content, which is determined based on protocol predefined information or network configuration information. In some embodiments, the transmitted content on other transmission resources is indicated based on the sequence index corresponding to the sequence.

[0623] In some embodiments, a sequence index is an identifier for a sequence, and the sequence index is an index number used to uniquely identify and select a specific resource or configuration. Optionally, the first indication information is carried by multiple sequences, that is, the first indication information is indicated jointly by multiple sequences. The sequence index is an identifier for multiple sequences.

[0624] In some embodiments, the sequence used to carry the first indication information is determined by a first parameter. The first parameter includes at least one of the following: a parameter for determining the initial value of the pseudo-random sequence generator; a parameter for determining the cyclic shift value; and a parameter for determining the base sequence number. The correspondence between the network device configuration of the first parameter and the transmission content indicated by the first indication information is shown in Table 25 below.

[0625] Table 25

[0626] The first parameter can take the value of at least one of the following: the initial value of the pseudo-random sequence generator, the cyclic shift value, and the base sequence number.

[0627] For example, there is a correspondence between the value of the first parameter and the transmitted content. Optionally, when the first parameter is a first value, the corresponding transmitted content is no transmission on the second transmission resource; when the first parameter is a second value, the corresponding transmitted content is DCI or PDCCH transmission on the second transmission resource; when the first parameter is a third value, the corresponding transmitted content is downlink data transmission on the second transmission resource; when the first parameter is a fourth value, the corresponding transmitted content is DCI and downlink data transmission on the second transmission resource; when the first parameter is a fifth value, the corresponding transmitted content is no transmission on the third transmission resource; when the first parameter is a sixth value, the corresponding transmitted content is feedback information transmission on the third transmission resource; when the first parameter is a seventh value, the corresponding transmitted content is uplink data transmission on the third transmission resource; when the first parameter is an eighth value, the corresponding transmitted content is feedback information and uplink data transmission on the third transmission resource. The correspondence between the value of the first parameter and the transmitted content is determined based on protocol predefined information or network configuration information.

[0628] It should be noted that Table 25 above is merely an illustrative example of the correspondence between the values ​​of the first parameter and the transmitted content, and does not constitute a limitation on the correspondence between the values ​​of the first parameter and the transmitted content. For example, when the first parameter is a first value, the transmitted content can be indicated as no transmission on the third transmission resource and transmission of DCI or PDCCH on the second transmission resource; as another example, when the first parameter is a second value, the transmitted content can be indicated as transmission of feedback information and uplink data on the third transmission resource.

[0629] It should be noted that the correspondence of network configurations only includes a portion of the content in the table above, such as any two rows in the table; in some implementations, the correspondence of network configurations includes a sequence length of K, and the corresponding transmission content is also K, where K is an integer greater than or equal to 1. This application does not impose any limitations on this.

[0630] In some embodiments, the network device is configured with sequence indices of different sequences. Optionally, different sequence indices can be used to indicate different transmission content on other transmission resources. This application will not elaborate on this.

[0631] Regarding the above instruction method E:

[0632] 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.

[0633] In some embodiments, the sequence group index corresponding to the sequence indicates the transmission content on other transmission resources.

[0634] In some embodiments, a sequence group consists of one or more sequences, and a sequence group index is used to identify a sequence group, which is used to determine a set of related sequences. In some embodiments, the sequence group used to carry the first indication information is determined by a first parameter. Optionally, the network device configures the correspondence between the first parameter and the transmission content indicated by the first indication information. The implementation can refer to indication method D described above, and will not be repeated here.

[0635] In some embodiments, the network device configures sequence group indexes with different sequences. Optionally, different sequence group indexes indicate different transmission content on other transmission resources. This application will not elaborate on this.

[0636] In some embodiments, in the above indication methods A to E, determining the transmission content of the second transmission resource and the third transmission resource simultaneously based on different first information associated with the first indication information can be understood as simultaneously indicating the transmission content of the second transmission resource and the third transmission resource based on different first information associated with the first indication information.

[0637] In some embodiments, the transmission content of the second transmission resource and the third transmission resource can be indicated simultaneously based on sequence length, frequency domain resources, time domain resources, sequence index, and sequence group index.

[0638] For example, the first information includes the length of the sequence. When the sequence length is a first length, the corresponding transmission content is no transmission on the second transmission resource and no transmission on the third transmission resource; when the sequence length is a second length, the corresponding transmission content is DCI or PDCCH transmission on the second transmission resource and no transmission on the third transmission resource; when the sequence length is a third length, the corresponding transmission content is downlink data transmission on the second transmission resource and feedback information transmission on the third transmission resource; when the sequence length is a fourth length, the corresponding transmission content is downlink data transmission on the second transmission resource and uplink data transmission on the third transmission resource. This is merely an illustrative example and does not constitute a limitation on the transmission content of the second and third transmission resources.

[0639] For example, the first information includes the frequency domain resources of the sequence. The first transmission resource is divided into multiple (e.g., four) sub-frequency domains, with sub-frequency domain range indices of "0", "1", "2", and "3" respectively. When the sub-frequency domain range index of the first transmission resource is "0", the corresponding transmission content is no transmission on the second transmission resource and no transmission on the third transmission resource; when the sub-frequency domain range index of the first transmission resource is "1", the corresponding transmission content is DCI or PDCCH transmission on the second transmission resource and no transmission on the third transmission resource; when the sub-frequency domain range index of the first transmission resource is "2", the corresponding transmission content is downlink data transmission on the second transmission resource and feedback information transmission on the third transmission resource; when the sub-frequency domain range index of the first transmission resource is "3", the corresponding transmission content is downlink data transmission on the second transmission resource and uplink data transmission on the third transmission resource. This is merely an illustrative example and does not constitute a limitation on the transmission content of the second and third transmission resources.

[0640] In some embodiments, the first indication information can simultaneously indicate the transmission content and the values ​​of the transmission parameters corresponding to the transmission content. Optionally, the first indication information is carried by first information associated with the first sequence. The transmission content and the values ​​of the transmission parameters corresponding to the transmission content on other transmission resources are determined based on the different first information associated with the first indication information. The first information is determined based on at least one of the following: the length of the sequence; the frequency domain resource corresponding to the sequence; the time domain resource corresponding to the sequence; the sequence index corresponding to the sequence; and the sequence group index corresponding to the sequence.

[0641] In some embodiments, the first indication information can be jointly indicated by at least two of the following: the length corresponding to the sequence; the frequency domain resource corresponding to the sequence; the time domain resource corresponding to the sequence; the sequence index corresponding to the sequence; and the sequence group index corresponding to the sequence. That is, the transmission content and the value of the transmission parameters corresponding to the transmission content can be jointly indicated by at least two of the following: the length corresponding to the sequence; the frequency domain resource corresponding to the sequence; the time domain resource corresponding to the sequence; the sequence index corresponding to the sequence; and the sequence group index corresponding to the sequence.

[0642] For example, in one possible implementation, the transmission content on other transmission resources is indicated based on the length corresponding to the sequence, while the values ​​of transmission parameters corresponding to the transmission content on other transmission resources are indicated based on the frequency domain resources corresponding to the sequence; or, the transmission content on other transmission resources is indicated based on the length corresponding to the sequence, while the values ​​of transmission parameters corresponding to the transmission content on other transmission resources are indicated based on the time domain resources corresponding to the sequence; or, the transmission content on other transmission resources is indicated based on the length corresponding to the sequence, while the values ​​of transmission parameters corresponding to the transmission content on other transmission resources are indicated based on the sequence index corresponding to the sequence; or, the transmission content on other transmission resources is indicated based on the frequency domain resources corresponding to the sequence, while the values ​​of transmission parameters corresponding to the transmission content on other transmission resources are indicated based on the time domain resources corresponding to the sequence; or, the transmission content on other transmission resources is indicated based on the frequency domain resources corresponding to the sequence, while the values ​​of transmission parameters corresponding to the transmission content on other transmission resources are indicated based on the sequence index corresponding to the sequence; or, the transmission content on other transmission resources is indicated based on the sequence index corresponding to the sequence, while the values ​​of transmission parameters corresponding to the transmission content on other transmission resources are indicated based on the sequence group index corresponding to the sequence. It should be noted that the above joint indications are merely illustrative examples and do not exhaust all possible combinations.

[0643] The transmission content on the aforementioned other transmission resources includes at least one of the following: no transmission on the second transmission resource; transmission of DCI or PDCCH on the second transmission resource; transmission of downlink data on the second transmission resource; transmission of both DCI and downlink data on the second transmission resource; no transmission on the third transmission resource; transmission of feedback information on the third transmission resource; transmission of uplink data on the third transmission resource; transmission of both feedback information and uplink data on the third transmission resource. The transmission parameters corresponding to the transmission content on the aforementioned other transmission resources include at least one of the following: the aggregation level corresponding to the downlink control information or downlink control channel; the number of CCEs corresponding to the downlink control information or downlink control channel; the number of resources used for transmitting downlink control information or downlink control channel; the modulation scheme corresponding to the downlink data; the MCS level corresponding to the downlink data; the MCS table corresponding to the downlink data; the TBS corresponding to the downlink data; the modulation scheme corresponding to the uplink data; the MCS level corresponding to the uplink data; the MCS table corresponding to the uplink data; the TBS corresponding to the uplink data.

[0644] Figure 14 illustrates a flowchart of a communication 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:

[0645] Step 1210: Obtain the second indication information, which is used to indicate the configuration information.

[0646] In some embodiments, the terminal device obtains second indication information, which is used to indicate configuration information, and the configuration information includes at least one of the following:

[0652] • The number of transport layers;

[0653] • Antenna port information;

[0654] • Rate matching indication information;

[0655] • Demodulation reference signal information.

[0656] In some embodiments, the second indication information and the first indication information are carried in the same indication information, or the second indication information is determined based on protocol predefined information or network configuration information.

[0657] In summary, the method provided in this application embodiment allows a terminal device to obtain first indication information on a first transmission resource configured on a network device. This first indication information is used to indicate transmission content on other transmission resources. The terminal device can also obtain second indication information, which is used to indicate configuration information, including downlink control information, downlink control channel information, or downlink data-related information transmitted on the second transmission resource.

[0658] In some embodiments, the second transmission resources configured by the network device are used to transmit downlink control information detection or downlink control channel. The terminal device performs downlink control information detection or downlink control channel detection based on configuration information, which includes at least one of the following: downlink control information format, the number of information bits corresponding to the downlink control information, RNTI information, encoding information, and code rate. This allows the terminal device to detect downlink control information or downlink control channel more accurately, reducing the probability of false detections and missed detections.

[0659] In some embodiments, the second transmission resources configured by the network device are used to transmit downlink data. The terminal device detects downlink data based on configuration information. The configuration information corresponding to the downlink data is determined based on protocol definition information or network configuration. The configuration information includes at least one of the following: the number of transport layers, antenna port information, rate matching indication information, and demodulation reference signal information. The configuration information helps the terminal device effectively utilize the second transmission resources, ensuring efficient and rational resource allocation and avoiding resource waste.

The multiplexing of downlink control information and downlink data on the second transmission resource includes at least one of the following: downlink control information is carried via a MAC CE, and the MAC CE and downlink data information are carried via a downlink shared channel; or, downlink data is carried via a downlink shared channel, with the downlink control information and downlink data corresponding to different resources in the second transmission resource. By multiplexing downlink control information and downlink data on the same transmission resource, limited spectrum resources can be utilized more efficiently, and different multiplexing methods can increase the flexibility and reliability of data transmission.

[0661] In some embodiments, feedback information and uplink data are transmitted on a third transmission resource configured in the network device. The multiplexing of feedback information and uplink data on the third transmission resource includes at least one of the following: feedback information is carried via a MAC CE, and the MAC CE and uplink data information are carried via an uplink shared channel; or, uplink data is carried via an uplink shared channel, and the uplink shared channel corresponds to different resources in the third transmission resource. By multiplexing feedback information and uplink data on the same transmission resource, limited spectrum resources can be utilized more efficiently, while transmission delays between information can be reduced.

[0662] In some embodiments, the first indication information is used to indicate whether there is a transmission on other transmission resources; when the first indication information indicates that there is a transmission on other transmission resources, the first indication information is used to indicate the transmission content on other transmission resources.

[0663] In some embodiments, the first indication information is used to indicate whether there is transmission on the second transmission resource and / or the third transmission resource; when the first indication information indicates that there is transmission on the second transmission resource, the first indication information is used to indicate the content of transmission on the second transmission resource; when the first indication information indicates that there is transmission on the third transmission resource, the first indication information is used to indicate the content of transmission on the third transmission resource. By informing other transmission resources in advance of whether there is transmission and the specific content of transmission through the first indication information, the terminal device can schedule and receive data more efficiently, reduce transmission latency, improve overall transmission efficiency, and save energy consumption of the terminal device.

[0664] It should be noted that the above embodiments can be combined with different indication methods of the first indication information to form new embodiments, or the above embodiments can be combined with different mapping methods of the sequence to form new embodiments, or the above embodiments can be combined with the embodiments of FIG7, FIG8, and FIG14 to form new embodiments.
