[0058] The following section describes the relevant technologies involved in the embodiments of this application:
[0059] • Physical downlink control channel detection:
[0060] Network devices send Data Interchange Channels (DCIs) to terminal devices. DCIs are used for downlink scheduling, such as scheduling the Physical Downlink Shared Channel (PDSCH), or for uplink granting, such as scheduling the Physical Uplink Shared Channel (PUSCH), or for transmitting common control information. DCIs are carried over PDCCHs. Network devices configure a search space for terminal devices. Different aggregation levels (ALs) can be configured, and at each aggregation level, the number of candidate PDCCHs the terminal device needs to monitor is configured. Terminal devices need to perform PDCCH detection within the search space. Since the terminal device does not know which resources in the search space the network device will transmit PDCCHs on, it needs to detect each candidate PDCCH resource in the search space; this process is called blind PDCCH detection. The maximum number of PDCCHs a terminal device needs to monitor in a time slot is related to the subcarrier spacing. For example, with a 15kHz subcarrier spacing, the maximum number of PDCCHs a terminal device needs to monitor in a 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.
[0061] Table 1
[0062] 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.
[0063] A PDCCH's transmission resources can include M1 Control Channel Elements (CCEs), corresponding to different aggregation levels (ALs). For example, M1 = 1, 2, 4, 8, 16. The relationship between aggregation level and the number of CCEs is shown in Table 2 below. Each CCE can include M2 Resource Element Groups (REGs). For example, M2 = 6. One REG corresponds to a Physical Resource Block (PRB) in the frequency domain and an Orthogonal Frequency Division Multiplexing (OFDM) symbol in the time domain. The transmission reliability varies depending on the number of CCEs occupied by the PDCCH. For example, the more CCEs a PDCCH occupies, the higher its transmission reliability.
[0064] Table 2
[0065] • Optimization of terminal device complexity:
[0066] Terminal devices, often simply referred to as terminals, are designed to support extremely high peak data rates. Therefore, the requirements for terminal capabilities are quite high. The LTE standard defines a maximum single-carrier bandwidth of 20MHz, with larger bandwidths achieved through multi-carrier aggregation. 5G NR ultimately defines a maximum carrier bandwidth of 100MHz for frequencies below 6GHz, five times that of LTE, while the maximum carrier bandwidth for millimeter-wave frequencies is 400MHz. The required multiple-input multiple-output (MIMO) antenna configuration for NR has also been further increased. The reference antenna configuration for LTE terminals is one transmit and two receive antennas, while NR R15 requires two transmit and four receive antennas at frequencies above 2500MHz.
[0067] However, some NR applications do not require such high processing power in terms of capacity and speed. These applications include the Internet of Things (IoT), industrial automation, and wearable devices. These scenarios demand communication hardware with low size and power consumption; lightweight capability is a characteristic of these terminals. Based on this consideration, NR Release 17 research introduced a compact terminal standard with reduced capability (RedCap).
[0068] 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.
[0069] 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.
[0070] In some embodiments, the set of transmission resources configured by the network device for the terminal device includes at least two types of transmission resources.
[0071] Optionally, a set of transmission resources includes a first transmission resource and other transmission resources, where the other transmission resources are those other than the first transmission resource. For example, the other transmission resources include a second transmission resource. The first transmission resource is used to transmit first indication information, and the second transmission resource is used for downlink transmission. The transmission content of the downlink transmission (i.e., the downlink transmission content) includes downlink data and / or downlink control information (DCI). The following embodiments primarily illustrate this by citing the inclusion of a second transmission resource among the other transmission resources, but are not limited thereto; for example, the other transmission resources may also include a third transmission resource.
[0072] In this embodiment, the network device configures a first transmission resource and a second transmission resource to the terminal device, and there is an association between the first transmission resource and the second transmission resource. The terminal device can determine the location of the second transmission resource based on the location of the first transmission resource.
[0073] Correspondence between the first transmission resource and the second transmission resource
[0074] In some embodiments, the correspondence may also be referred to as the association.
[0075] In some embodiments, the correspondence between the first transmission resource and the second transmission resource is one-to-one, many-to-one, one-to-many, or many-to-many; wherein, one-to-one means that one first transmission resource corresponds to one second transmission resource, many-to-one means that multiple first transmission resources correspond to the same second transmission resource, one-to-many means that one first transmission resource corresponds to multiple second transmission resources, and many-to-many means that multiple first transmission resources correspond to multiple second transmission resources.
[0076] Optionally, when the correspondence between the first transmission resources and the second transmission resources is many-to-one, at least one of the time-domain resources, frequency-domain resources, or code-domain resources corresponding to the multiple first transmission resources is different. For example, the multiple first transmission resources have the same time-domain resources but different frequency-domain resources; or, the multiple first transmission resources have different time-domain resources but the same frequency-domain resources; or, the multiple first transmission resources have different time-domain resources and different frequency-domain resources; or, the multiple first transmission resources have the same time-domain resources and the same frequency-domain resources, but different code-domain resources. For example, the multiple first transmission resources are located in the same time-domain symbol, but the corresponding PRBs are different; or, the multiple first transmission resources are located in different time-domain symbols, but the same frequency-domain resources; or, the multiple first transmission resources are located in different time-domain symbols, but different frequency-domain resources; or, the multiple first transmission resources are located in the same time-domain symbol, but the same frequency-domain resources, but correspond to different sequences.
[0077] Optionally, when the correspondence between the first and second transmission resources is one-to-many, the multiple second transmission resources have the same time-domain resources but different frequency-domain resources; or, the multiple second transmission resources have different time-domain resources but the same frequency-domain resources; or, the multiple second transmission resources have different time-domain resources and different frequency-domain resources. For example, the multiple second transmission resources are located in the same time-domain symbol, but their corresponding PRBs are different; or, for another example, the multiple second transmission resources have different time-domain resources but the same frequency-domain resources; or, for yet another example, the multiple second transmission resources have different time-domain resources and different frequency-domain resources.
[0078] Optionally, when the correspondence between the first transmission resource and the second transmission resource is many-to-many, if the multiple first transmission resources include A first transmission resources and the multiple second transmission resources include B second transmission resources, then A1 first transmission resources correspond to B1 second transmission resources, where A, A1, B, and B1 are integers, 1≤A1≤A, and 1≤B1≤B.
[0079] Figure 2 illustrates a schematic diagram of the correspondence between transmission resources provided in an exemplary embodiment of this application.
[0080] In Figure 2(a), the first transmission resource and the second transmission resource have a one-to-one correspondence, that is, one first transmission resource corresponds to one second transmission resource; in Figure 2(b), the first transmission resource and the second transmission resource have a many-to-one correspondence, that is, two first transmission resources correspond to the same second transmission resource; in Figure 2(c), the first transmission resource and the second transmission resource have a one-to-many correspondence, that is, one first transmission resource corresponds to two second transmission resources; in Figure 2(d), the first transmission resource and the second transmission resource have a many-to-many correspondence, that is, any one of the two first transmission resources corresponds to both of the two second transmission resources, or, any one of the two first transmission resources corresponds to either of the two second transmission resources.
[0081] Positional relationship between the first transmission resource and the second transmission resource
[0082] In some embodiments, the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the location of the second transmission resource and the location of the first transmission resource based on a communication protocol; or, there is a pre-configured relationship between the location of the second transmission resource and the location of the first transmission resource based on a network.
[0083] By way of example and not limitation, the positional relationship between the first transmission resource and the second transmission resource includes at least one of the following:
[0084] The first transmission resource and the second transmission resource are not adjacent in the time domain; the first transmission resource and the second transmission resource are adjacent in the time domain; the start position of the time domain of the first transmission resource is the same as the start position of the time domain of the second transmission resource; the start position of the frequency domain of the first transmission resource is the same as the start position of the frequency domain of the second transmission resource; the center position of the frequency domain of the first transmission resource is the same as the center position of the frequency domain of the second transmission resource; the end position of the frequency domain of the first transmission resource is the same as the end position of the frequency domain of the second transmission resource.
[0085] The temporal adjacency between the first transmission resource and the second transmission resource means that the temporal end position of the first transmission resource is adjacent to the temporal start position of the second transmission resource.
[0086] Figure 3 illustrates a schematic diagram of the positional relationship between transmission resources provided in an exemplary embodiment of this application.
[0087] 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.
[0088] 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.
[0089] 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.
[0090] 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.
[0091] 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.
[0092] Types of first and second transmission resources
[0093] In some embodiments, the first transmission resource and the second transmission resource are common transmission resources shared by multiple terminal devices; or, the first transmission resource and the second transmission resource are group transmission resources shared by a group of terminal devices; or, the first transmission resource and the second transmission resource are proprietary transmission resources used by a single terminal device.
[0094] In some embodiments, when the first transmission resource and the second transmission resource are common transmission resources shared by multiple terminal devices or group transmission resources shared by a group of terminal devices, the second transmission resource is used to transmit common DCI and / or common downlink data. The common DCI and / or common downlink data is used to transmit at least one of the following information: broadcast information, system information, paging information, and random access response information.
[0095] In some embodiments, the network device configures the same first transmission resource and the same second transmission resource for multiple terminal devices, that is, the first transmission resource and the second transmission resource are shared by multiple terminal devices; the network device configures the same sequence for multiple terminal devices, or the network device configures their respective corresponding sequences for multiple terminal devices, and the terminal devices detect the first indication information on the first transmission resource based on the configured sequence.
[0096] 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.
[0097] 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.
[0098] The network device is configured with a first transmission resource and a second transmission resource for transmitting common DCI and / or common downlink data. A first indication information is transmitted on the first transmission resource, the sequence corresponding to the first indication information being a common sequence. Common DCI and / or common downlink data are transmitted on the second transmission resource.
[0099] In some embodiments, multiple terminal devices detect whether there is first indication information on the first transmission resource based on the same common sequence.
[0100] 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.
[0101] 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.
[0102] 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.
[0103] 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.
[0104] 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.
[0105] Optionally, network devices can be configured with different types of group transmission resources. It should be noted that the "group" in group transmission resources here refers to a terminal group, not the group in the group transmission resources mentioned above.
[0106] In some embodiments, in a first configuration, the network device configures a group transmission resource shared by a group of terminal devices, including a first group transmission resource and a second group transmission resource. The second group transmission resource is used to transmit group common DCI or group common downlink data. Optionally, the terminal device group includes all terminal devices within the cell, and the first group transmission resource and the second group transmission resource can also be referred to as shared first transmission resource and shared second transmission resource. For example, the common DCI and common downlink data are used to transmit at least one of the following: slot format information, channel occupation time duration information, available resource block set information, search space set group switching information, pre-emption indication information, transmission power control (TPC), uplink transmission cancellation indication information, and wake-up indication information.
[0107] In some embodiments, in the second configuration, the network device configures a group transmission resource shared by a group of terminal devices, including a group second transmission resource. The network device configures different first transmission resources for the group of terminal devices. For example, the network device configures the same second transmission resource for the group of terminal devices, but configures different first transmission resources. For each terminal device, there is an association between its configured first transmission resource and second transmission resource; this configuration method can enable multiple terminal devices to reuse or share the second transmission resource.
[0108] For example, Figure 4 shows a schematic diagram of the configuration transmission resources provided in an exemplary embodiment of this application.
[0109] Part (a) in Figure 4 corresponds to the first configuration method described above, where the network device configures the same first transmission resource and the same second transmission resource for UE1 and UE2, and UE1 and UE2 share the first and second transmission resources. In some embodiments, the network device only sends the first indication information to UE1 to indicate the transmission content on the second transmission resource. UE1 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource. In some embodiments, the network device only sends the first indication information to UE2 to indicate the transmission content on the second transmission resource. UE2 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource.
[0110] Part (b) in Figure 4 corresponds to the second configuration described above, where the network device configures the same second transmission resource for UE1 and UE2, and different first transmission resources for UE1 and UE2, with UE1 and UE2 sharing the second transmission resource. In some embodiments, the network device only sends the first indication information for UE1 to indicate that UE1's transmission content is being transmitted on the second transmission resource, without sending the first indication information for UE2, or sends the first indication information for UE2 to indicate that there is no transmission on the second transmission resource. UE1 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource. UE2 determines that detection is not needed on the second transmission resource based on the first indication information detected on the first transmission resource. In some embodiments, the network device only sends the first indication information for UE2 to indicate that UE2's transmission content is being transmitted on the second transmission resource, without sending the first indication information for UE1, or sends the first indication information for UE1 to indicate that there is no transmission on the second transmission resource. UE2 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource. UE1 determines that detection is not needed on the second transmission resource based on the first indication information detected on the first transmission resource.
[0111] Part (c) of Figure 4 corresponds to the second configuration method described above. Part (c) of Figure 4 has the same configuration method as part (b) of Figure 4, that is, the network device configures the same second transmission resource for UE1 and UE2, and configures different first transmission resources for UE1 and UE2. UE1 and UE2 share the second transmission resource. In part (c) of Figure 4, the first indication information sent by the network device to either UE1 or UE2 indicates the value of the transmission parameters corresponding to the content transmitted on the second transmission resource. For example, the first indication information sent on the first transmission resource of UE1 indicates that the transmission resource of UE1's DCI occupies only half of the second transmission resource; the first indication information sent on the first transmission resource of UE2 also indicates that the transmission resource of UE2's DCI occupies only half of the second transmission resource, and UE1 and UE2 occupy different resources on the second transmission resource, thus allowing the two UEs to simultaneously reuse the second transmission resource for transmission.
[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. The user-specific first transmission resource is used to transmit a first indication information specific to each terminal device, and the user-specific second transmission resource is used to transmit a user-specific DCI or user-specific downlink data for each terminal device.
[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 5 illustrates a schematic diagram of the configuration of transmission resources provided in an exemplary embodiment of this application. The network device is configured with common transmission resources, group transmission resources, and dedicated transmission resources. The common transmission resources include two groups of common first transmission resources and two groups of common second transmission resources; the group transmission resources include two groups of group first transmission resources and two groups of group second transmission resources; and the dedicated transmission resources include eight groups of dedicated first transmission resources and dedicated second transmission resources. For the dedicated transmission resources, the network device can configure one or more dedicated first transmission resources and dedicated second transmission resources for each terminal device. Assuming the network device configures one group of common first transmission resources and one group of common second transmission resources, one group of group first transmission resources and one group of group second transmission resources, and two groups of dedicated first transmission resources and dedicated second transmission resources for a terminal device, the terminal device needs to perform detection in these four groups of transmission resources (e.g., detecting the presence of first indication information in the first transmission resources), and then detect DCI and / or downlink data in the corresponding second transmission resources. By dividing a set of transmission resources into different types of transmission resources, and with network devices configured with at least one of public transmission resources, group transmission resources, and dedicated transmission resources, the scope of terminal device detection is narrowed, and detection efficiency is improved.
[0115] In the above embodiments, the first indication information can be used to indicate the transmission content in the second transmission resource, such as indicating that a DCI is transmitted on the second transmission resource. The DCI transmitted on the second transmission resource can correspond to various transmission parameters. When the first indication information is carried by a sequence, and the first indication information carried by the sequence simultaneously indicates the transmission of a DCI and the corresponding transmission parameters on the second transmission resource, on the one hand, the information that the sequence can carry is limited, and on the other hand, the detection complexity of the terminal device will increase. Therefore, it is crucial to reduce the detection complexity of the DCI by the terminal device.
[0116] Figure 6 illustrates a flowchart of a transmission 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:
[0117] Step 610: Obtain first indication information on the first transmission resource. The first indication information is used to indicate the relevant information of the first DCI on the second transmission resource. The first DCI is used to indicate the relevant information of the second DCI on the third transmission resource.
[0118] Among these, at least two of the first, second, and third transmission resources are associated with each other, and the first DCI and / or the second DCI are used to schedule PDSCH or PUSCH transmissions. Alternatively, at least two of the first, second, and third transmission resources are configured as a set or in groups.
[0119] In some embodiments, before obtaining the first indication information on the first transmission resource, the terminal device also receives first configuration information sent by the network device. This can also be understood as the terminal device obtaining the first configuration information sent by the network device. Optionally, the first configuration information is used to configure an association relationship between at least two of the first, second, and third transmission resources. In some embodiments, the first configuration information configures the first and second transmission resources to be associated; or, the first and third transmission resources to be associated; or, the second and third transmission resources to be associated; or, the first, second, and third transmission resources to be associated.
[0120] Optionally, the first transmission resource and the second transmission resource are associated, including at least one of the following: the first transmission resource and the second transmission resource have a one-to-one relationship; the first transmission resource and the second transmission resource have a one-to-many relationship; the first transmission resource and the second transmission resource have a many-to-one relationship; the first transmission resource and the second transmission resource have a many-to-many relationship.
[0121] Optionally, the first transmission resource and the third transmission resource are associated, including at least one of the following: the first transmission resource and the third transmission resource have a one-to-one relationship; the first transmission resource and the third transmission resource have a one-to-many relationship; the first transmission resource and the third transmission resource have a many-to-one relationship; the first transmission resource and the third transmission resource have a many-to-many relationship.
[0122] Optionally, the second transmission resource and the third transmission resource are associated, including at least one of the following: the second transmission resource and the third transmission resource have a one-to-one relationship; the second transmission resource and the third transmission resource have a one-to-many relationship; the second transmission resource and the third transmission resource have a many-to-one relationship; the second transmission resource and the third transmission resource have a many-to-many relationship.
[0123] Optionally, the first transmission resource, the second transmission resource, and the third transmission resource are associated, including the first transmission resource and the second transmission resource being associated, and the second transmission resource and the third transmission resource being associated. The correspondence between the first transmission resource and the second transmission resource is one-to-one; or one-to-many; or many-to-one; or many-to-many. The correspondence between the second transmission resource and the third transmission resource is one-to-one; or one-to-many; or many-to-one; or many-to-many.
[0124] In some embodiments, the network device configures a first transmission resource and a second transmission resource to be associated. The first transmission resource is used to transmit first indication information, which indicates that there is no transmission or that a first DCI is being transmitted on the second transmission resource. If the first indication information indicates that a first DCI is being transmitted on the second transmission resource, the network device transmits the first DCI on the second transmission resource. The first DCI is used to indicate information related to a second DCI on a third transmission resource. In some embodiments, the first DCI is also used to indicate scheduling information (which includes a portion of the scheduling information for PDSCH or PUSCH transmission). The network device transmits the second DCI on the third transmission resource, and the second DCI is used to indicate all or a portion of the scheduling information for PDSCH or PUSCH transmission. For example, as shown in FIG7, the terminal device obtains first indication information on the first transmission resource, which indicates a first DCI on the second transmission resource, and the first DCI indicates information related to a second DCI on the third transmission resource.
[0125] In some embodiments, the network device transmits a first DCI on a second transmission resource, which may also be referred to as a first-order DCI, and the network device transmits a second DCI on a third transmission resource, which may also be referred to as a second-order DCI.
[0126] In some embodiments, the first DCI and / or the second DCI are used to schedule PDSCH or PUSCH transmissions.
[0127] In some embodiments, the first DCI is used to indicate relevant information of the second DCI, and the second DCI is used to schedule PDSCH or PUSCH transmissions.
[0128] In some embodiments, the first DCI is used to indicate relevant information of the second DCI and includes a portion of the scheduling information for the PDSCH or PUSCH transmission, and the second DCI includes another portion of the scheduling information for the PDSCH or PUSCH transmission.
[0129] Optionally, the first DCI and the second DCI jointly schedule PDSCH or PUSCH transmissions. The first DCI is used not only to indicate relevant information of the second DCI, such as transmission parameters and / or transmission resources, but also to indicate a first portion of the information in the PDSCH or PUSCH transmission, while the second DCI indicates another portion of the information. For example, referring to FIG8, the terminal device obtains first indication information on a first transmission resource. This first indication information indicates the first DCI on a second transmission resource, and the first DCI is used to indicate the second DCI on a third transmission resource. The first DCI and the second DCI jointly schedule PDSCH or PUSCH transmissions. The first DCI is also used to indicate a portion of the information in the PDSCH or PUSCH transmission on a fourth transmission resource, while the second DCI indicates another portion of the information in the PDSCH or PUSCH transmission on the fourth transmission resource.
[0130] Optionally, the second DCI is used to schedule PDSCH or PUSCH transmissions. The first DCI is used to indicate relevant information (or scheduling information, authorization information) of the second DCI, and the second DCI is used to indicate relevant information (or scheduling information, authorization information) of PDSCH or PUSCH transmissions. For example, referring to FIG9, the terminal device obtains first indication information on the first transmission resource. The first indication information indicates the first DCI on the second transmission resource, and the first DCI is used to indicate the second DCI on the third transmission resource. The second DCI is used to schedule PDSCH or PUSCH transmissions; for example, the second DCI is used to indicate the transmission parameters of PDSCH or PUSCH transmissions on the fourth transmission resource.
[0131] In summary, the method provided in this application embodiment allows the terminal device to obtain first indication information on the first transmission resource. By detecting the first indication information on the first transmission resource, it can determine whether it is necessary to detect the first DCI (also known as the first-order DCI) on the second transmission resource based on the first indication information. Then, it can confirm the relevant information of the second DCI (also known as the second-order DCI) based on the first DCI. This method schedules PDSCH or PUSCH transmission through two-order DCI. This tiered scheduling method can reduce the complexity of DCI detection.
[0132] Furthermore, for each group of transmission resources, only the first indication information on the first transmission resource needs to be detected. Based on the first indication information, the transmission behavior on subsequent transmission resources is determined. Compared with blind detection in related technologies, blind detection is not required or its complexity is reduced, achieving the effect of energy saving and consumption reduction.
[0133] Figure 10 illustrates a flowchart of a transmission method provided by some exemplary embodiments of this application. The method is illustrated illustratively, taking the execution of the method by a network device as an example. The method includes:
[0134] Step 710: Send first indication information on the first transmission resource. The first indication information is used to indicate the relevant information of the first DCI on the second transmission resource. The first DCI is used to indicate the relevant information of the second DCI on the third transmission resource.
[0135] Among these, at least two of the first, second, and third transmission resources are associated with each other, and the first DCI and / or the second DCI are used to schedule PDSCH or PUSCH transmissions. Alternatively, at least two of the first, second, and third transmission resources are configured as a set or in groups.
[0136] In some embodiments, before the terminal device obtains the first indication information on the first transmission resource, the network device further sends first configuration information to the terminal device. Optionally, the first configuration information is used to configure an association relationship between at least two of the first, second, and third transmission resources. In some embodiments, the first configuration information configures the first and second transmission resources to be associated; or, the first and third transmission resources to be associated; or, the second and third transmission resources to be associated; or, the first, second, and third transmission resources to be associated.
[0137] Optionally, the first transmission resource and the second transmission resource are associated, including at least one of the following: the first transmission resource and the second transmission resource have a one-to-one relationship; the first transmission resource and the second transmission resource have a one-to-many relationship; the first transmission resource and the second transmission resource have a many-to-one relationship; the first transmission resource and the second transmission resource have a many-to-many relationship.
[0138] Optionally, the first transmission resource and the third transmission resource are associated, including at least one of the following: the first transmission resource and the third transmission resource have a one-to-one relationship; the first transmission resource and the third transmission resource have a one-to-many relationship; the first transmission resource and the third transmission resource have a many-to-one relationship; the first transmission resource and the third transmission resource have a many-to-many relationship.
[0139] Optionally, the second transmission resource and the third transmission resource are associated, including at least one of the following: the second transmission resource and the third transmission resource have a one-to-one relationship; the second transmission resource and the third transmission resource have a one-to-many relationship; the second transmission resource and the third transmission resource have a many-to-one relationship; the second transmission resource and the third transmission resource have a many-to-many relationship.
[0140] Optionally, the first transmission resource, the second transmission resource, and the third transmission resource are associated, including the first transmission resource and the second transmission resource being associated, and the second transmission resource and the third transmission resource being associated. The correspondence between the first transmission resource and the second transmission resource is one-to-one; or one-to-many; or many-to-one; or many-to-many. The correspondence between the second transmission resource and the third transmission resource is one-to-one; or one-to-many; or many-to-one; or many-to-many.
[0141] In some embodiments, the network device configures a first transmission resource and a second transmission resource to be associated. The first transmission resource is used to transmit first indication information, which indicates that there is no transmission or that a first DCI is being transmitted on the second transmission resource. If the first indication information indicates that a first DCI is being transmitted on the second transmission resource, the network device transmits the first DCI on the second transmission resource. The first DCI is used to indicate information related to a second DCI on a third transmission resource. In some embodiments, the first DCI is also used to indicate scheduling information (which includes a portion of the scheduling information for PDSCH or PUSCH transmission). The network device transmits the second DCI on the third transmission resource, and the second DCI is used to indicate all or a portion of the scheduling information for PDSCH or PUSCH transmission. For example, as shown in FIG7, the terminal device obtains first indication information on the first transmission resource, which indicates a first DCI on the second transmission resource, and the first DCI indicates information related to a second DCI on the third transmission resource.
[0142] In some embodiments, the network device transmits a first DCI on a second transmission resource, which may also be referred to as a first-order DCI, and the network device transmits a second DCI on a third transmission resource, which may also be referred to as a second-order DCI.
[0143] In some embodiments, the first DCI and / or the second DCI are used to schedule PDSCH or PUSCH transmissions.
[0144] In some embodiments, the first DCI is used to indicate relevant information of the second DCI, and the second DCI is used to schedule PDSCH or PUSCH transmissions.
[0145] In some embodiments, the first DCI is used to indicate relevant information of the second DCI and includes a portion of the scheduling information for the PDSCH or PUSCH transmission, and the second DCI includes another portion of the scheduling information for the PDSCH or PUSCH transmission.
[0146] Optionally, the first DCI and the second DCI jointly schedule PDSCH or PUSCH transmissions. The first DCI is used not only to indicate relevant information of the second DCI, such as transmission parameters and / or transmission resources, but also to indicate a first portion of the information in the PDSCH or PUSCH transmission, while the second DCI indicates another portion of the information. For example, referring to FIG8, the terminal device obtains first indication information on a first transmission resource. This first indication information indicates the first DCI on a second transmission resource, and the first DCI is used to indicate the second DCI on a third transmission resource. The first DCI and the second DCI jointly schedule PDSCH or PUSCH transmissions. The first DCI is also used to indicate a portion of the information in the PDSCH or PUSCH transmission on a fourth transmission resource, while the second DCI indicates another portion of the information in the PDSCH or PUSCH transmission on the fourth transmission resource.
[0147] Optionally, the second DCI is used to schedule PDSCH or PUSCH transmissions. The first DCI is used to indicate relevant information (or scheduling information, authorization information) of the second DCI, and the second DCI is used to indicate relevant information (or scheduling information, authorization information) of PDSCH or PUSCH transmissions. For example, referring to FIG9, the terminal device obtains first indication information on the first transmission resource. The first indication information indicates the first DCI on the second transmission resource, and the first DCI is used to indicate the second DCI on the third transmission resource. The second DCI is used to schedule PDSCH or PUSCH transmissions; for example, the second DCI is used to indicate the transmission parameters of PDSCH or PUSCH transmissions on the fourth transmission resource.
[0148] In summary, the method provided in this application involves a network device configuring a set of associated transmission resources. The terminal device obtains first indication information on the first transmission resource. It only needs to detect the first indication information on the first transmission resource to determine whether it is necessary to detect the first DCI (also known as the first-order DCI) on the second transmission resource. Then, it confirms the relevant information of the second DCI (also known as the second-order DCI) based on the first DCI. This method schedules PDSCH or PUSCH transmission through two-order DCI. This tiered scheduling method can reduce the complexity of DCI detection.
[0149] Furthermore, for each group of transmission resources, only the first indication information on the first transmission resource needs to be detected. Based on the first indication information, the transmission behavior on subsequent transmission resources is determined. Compared with blind detection in related technologies, blind detection is not required or its complexity is reduced, achieving the effect of energy saving and consumption reduction.
[0150] Next, based on the embodiments shown in Figures 6 and 10, the first indication information on the first transmission resource will be further described.
[0151] In some embodiments, a network device transmits first indication information on a first transmission resource, a terminal device obtains the first indication information on the first transmission resource, and determines the relevant information of the first DCI transmitted on a second transmission resource based on the first indication information.
[0152] The method of instruction for the first instruction information
[0153] Optionally, the first indication information indicates relevant information about the first DCI, including at least one of the following:
[0154] • Indicates that there is no transmission on the second transmission resource;
[0155] • Indicates that there is a first DCI transmission on the second transmission resource;
[0156] • Indicates the detection of the first DCI on the second transmission resource.
[0157] In some embodiments, the first indication information is used to indicate that no first DCI is transmitted on the second transmission resource. Optionally, a first value, a first state, or a first sequence is determined based on the first indication information, and the absence of first DCI transmission on the second transmission resource is determined based on the first value, the first state, or the first sequence. The first value is a single bit value or a set of bit values; for example, a single bit value of 0 represents the first value. The first state is an on or off state, which can be represented by a high or low voltage level, such as an off state representing the first state; it can also be represented by a bit value, such as the first indication information being carried by a single bit, where a single bit value of "FALSE," "F," "NO," or "N" represents the first state. The first sequence is a sequence used to represent the first indication information.
[0158] In some embodiments, the first indication information is used to indicate the transmission of the first DCI on the second transmission resource. Optionally, a second value, a second state, or a second sequence is determined based on the first indication information, and the transmission of the first DCI on the second transmission resource is determined based on the second value, the second state, or the second sequence. The second value is a single bit value or a set of bit values; for example, a bit value of 1 represents the second value. The second state is an on or off state, which can be represented by a high or low voltage level, such as an on state representing the second state; it can also be represented by a bit value, such as the first indication information being carried by 1 bit, where a bit value of "TRUE", "T", "YES", or "Y" represents the second state. The second sequence is another sequence used to represent the first indication information.
[0159] In some embodiments, the first indication information is used to indicate that the first DCI is detected on the second transmission resource. Optionally, the terminal device determines whether it needs to detect the first DCI on the second transmission resource based on whether it detects the first indication information. For example, if the terminal device does not detect the first indication information on the first transmission resource, it indicates that the first DCI is not transmitted on the second transmission resource, and the terminal device does not need to detect the second transmission resource. For example, if the terminal device detects the first indication information on the first transmission resource, the terminal device detects the second transmission resource, or detects the first DCI on the second transmission resource.
[0160] The first indication information is carried by a sequence or at least one bit.
[0161] In some embodiments, the first indication information is based on a sequence bearer. The first indication information being based on a sequence bearer can also be understood as indicating the first indication information in a sequential manner.
[0162] Optionally, the sequence type includes at least one of the following: Constant Amplitude Zero Auto-Corelation (CAZAC) sequence; ZC sequence; Pseudo-random sequence; Gold sequence; m-sequence; Hadamard sequence. Alternatively, the sequence used to carry the first indication information is generated or determined based on the above sequence types. Sending the first indication information in a sequence manner allows the terminal device to determine the information indicated by the first indication information based on sequence detection (such as sequence correlation detection), avoiding decoding processing and reducing the power consumption and processing latency of the terminal device.
[0163] In some embodiments, the length of the sequence is determined by at least one of the following methods: based on protocol predefined information; based on configuration information sent by the network device; or based on the size of the frequency domain resources included in the first transmission resource. Optionally, when determining the length of the sequence based on the configuration information sent by the network device, the configuration information may be the first configuration information sent by the network device, or other configuration information sent by the network device, and this application does not limit this.
[0164] For example, the first transmission resource includes K subcarriers or resource elements (REs), and the sequence length L is the largest prime number less than or equal to K, or the largest prime number less than or equal to (K / A), where A is a preset positive integer, such as A = 2 or 4. For example, the sequence length L is the largest prime number less than or equal to K, where K = 60 and L = 59; or K = 72 and L = 71; or K = 120 and L = 113.
[0165] In some embodiments, the first indication information is carried by at least one information bit. At least one information bit may also be referred to as a bit sequence.
[0166] For example, the first indication information is carried by a bit sequence comprising L bits, where L is an integer greater than or equal to 1.
[0167] In some embodiments, at least one information bit (or a bit sequence comprising L bits) is processed through channel coding, modulation, etc., to generate a data packet or transport block. Specifically, at least one bit may be encoded after adding a Cyclic Redundancy Check (CRC) code.
[0168] In some embodiments, the encoding method corresponding to at least one information bit includes at least one of the following: convolutional code; Manchester code; pulse interval encoding (PIE); bi-phase space coding; Miller coding. Optionally, the encoded at least one information bit is transmitted after modulation.
[0169] In some embodiments, the modulation scheme corresponding to at least one information bit includes at least one of the following: On-Off Keying (OOK) modulation; Phase Shift Keying (PSK) modulation; Binary Phase Shift Keying (BPSK) modulation; Frequency Shift Keying (FSK) modulation; and Orthogonal Frequency Division Multiplexing (OFDM) modulation.
[0170] The content of the first instruction information
[0171] In some embodiments, the first transmission resource is used to transmit first indication information. Optionally, the first transmission resource and the second transmission resource are associated, including a one-to-one relationship between the first transmission resource and the second transmission resource; a one-to-many relationship between the first transmission resource and the second transmission resource; a many-to-one relationship between the first transmission resource and the second transmission resource; and a many-to-many relationship between the first transmission resource and the second transmission resource.
[0172] In some embodiments, where there is a many-to-one relationship between the first transmission resource and the second transmission resource, a plurality of first indication information is transmitted on the plurality of first transmission resources. The plurality of first indication information is used to indicate at least one of the following transmission information:
[0173] Transmission Message 1: Indicates the content to be transmitted on the second transmission resource;
[0174] Transmission information two: Indicates the transmission parameters corresponding to the transmission content on the second transmission resource;
[0175] Transmission information three: Instruction to repeatedly transmit the first instruction information on at least two first transmission resources; the at least two first transmission resources are at least two of a plurality of first transmission resources.
[0176] In some embodiments, a plurality of first indication information is used to indicate the same transmission information; or, a plurality of first indication information is used to indicate different transmission information; or, a portion of a plurality of first indication information indicates the same transmission information, and another portion indicates different transmission information.
[0177] Optionally, multiple first indication messages are used to indicate the same transmission information. For example, a network device may configure two first transmission resources and one second transmission resource to be associated, that is, the second transmission resource is associated with two first transmission resources. Optionally, the two first transmission resources may be used to repeatedly transmit the same first indication message. For example, multiple first indication messages may be used to indicate the transmission content on the second transmission resource, and the first indication messages transmitted on the two first transmission resources may be used to indicate the transmission of a first DCI on the second transmission resource.
[0178] Optionally, multiple first indication information are used to indicate different transmission information. For example, a network device is configured to associate two first transmission resources and one second transmission resource; that is, the second transmission resource is associated with the two first transmission resources. Optionally, the two first transmission resources are used to indicate different transmission information. For example, the first indication information transmitted on the two first transmission resources is used to indicate the transmission content and corresponding transmission parameters on the second transmission resource: the first indication information transmitted on the first first transmission resource indicates that a first DCI is transmitted on the second transmission resource, and the first indication information transmitted on the second first transmission resource indicates the DCI format corresponding to the first DCI transmitted on the second transmission resource.
[0179] Optionally, a portion of the multiple first indication information indicates the same transmission information, while another portion indicates different transmission information. For example, a network device is configured to associate four first transmission resources with one second transmission resource; that is, the second transmission resource is associated with the four first transmission resources. Optionally, the four first transmission resources are divided into two groups, each group used to repeatedly transmit the same first indication information. For example, the first indication information repeatedly transmitted on two first transmission resources in the first group is used to indicate the transmission content on the second transmission resource, and the first indication information repeatedly transmitted on two first transmission resources in the second group is used to indicate the transmission parameters corresponding to the transmission content on the second transmission resource: the first indication information repeatedly transmitted on two first transmission resources in the first group is used to indicate the transmission of a first DCI on the second transmission resource, and the first indication information repeatedly transmitted on two first transmission resources in the second group is used to indicate the DCI format corresponding to the first DCI transmitted on the second transmission resource.
[0180] The three transmission methods described above will be introduced below.
[0181] Regarding the aforementioned transmitted information
[0182] In some embodiments, the first indication information is used at least to indicate the transmission content on the second transmission resource, including one or more pieces of first indication information used at least to indicate the transmission content on the second transmission resource. This application does not limit this.
[0183] The content transmitted on the second transmission includes either no transmission on the second transmission resource or transmission of the first DCI on the second transmission resource.
[0184] In some embodiments, the first indication information is carried by a sequence or information bits. The first indication information is used at least to indicate the transmission content on the second transmission resource, and can also be understood as indicating the transmission content on the second transmission resource based on the sequence or information bits carrying the first indication information. Optionally, different sequences or different information bits indicate different transmission content on the second transmission resource.
[0185] In some embodiments, the first indication information indicates at least the transmission content on the second transmission resource; or, the related information associated with the first indication information indicates at least the transmission content on the second transmission resource; or, the combination of the first indication information and the related information associated with the first indication information indicates at least the transmission content on the second transmission resource.
[0186] The relevant information includes at least one of the following: frequency domain resources corresponding to the first indication information, time domain resources corresponding to the first indication information, and first parameters corresponding to the sequence carrying the first indication information. Optionally, the first parameter includes at least one of the following: initial value corresponding to the sequence, cyclic shift value corresponding to the sequence, group number corresponding to the sequence, root sequence number within the group corresponding to the sequence, sequence length corresponding to the sequence, and sequence index corresponding to the sequence. That is, the relevant information includes at least one of eight types of information.
[0187] Taking the use of first indication information to indicate at least the transmission content on the second transmission resource as an example, the first indication information is carried by a sequence or information bits, and different sequences or different values of information bits can be used to indicate the transmission content on the second transmission resource.
[0188] Taking the use of relevant information to at least indicate the transmission content on the second transmission resource as an example, the following are at least nine different indication methods that can be used to indicate the transmission content on the second transmission resource, wherein the sequence is used to carry the first indication information.
[0189] Indication method A1: Based on the frequency domain resources corresponding to the first indication information, at least the transmission content on the second transmission resource is indicated;
[0190] Instruction method B1: Based on the time domain resources corresponding to the first instruction information, at least the transmission content on the second transmission resource is indicated;
[0191] Indication method C1: Based on the initial value corresponding to the sequence, at least the transmission content on the second transmission resource is indicated;
[0192] Indication method D1: Based on the cyclic shift value corresponding to the sequence, at least the transmission content on the second transmission resource is indicated;
[0193] Indication method E1: Based on the group number corresponding to the sequence, at least the transmission content on the second transmission resource is indicated;
[0194] Indication method F1: Based on the root sequence number within the group corresponding to the sequence, at least the transmission content on the second transmission resource is indicated;
[0195] Indication method G1: Based on the sequence length corresponding to the sequence, at least the transmission content on the second transmission resource is indicated;
[0196] Indication method H1: Based on the sequence index corresponding to the sequence, at least the transmission content on the second transmission resource is indicated;
[0197] Indication method I1: Indicates the transmission content on the second transmission resource based on a combination of at least two of the above indication methods.
[0198] For example, the frequency domain resources corresponding to the first indication information indicate at least the transmission content on the second transmission resource. There is an association or correspondence between the frequency domain resources corresponding to the first indication information and the transmission content, and this association or correspondence is determined based on protocol predefined information or network configuration information. The frequency domain resources corresponding to the first indication information can be understood as the frequency domain resources corresponding to the first transmission resource where the first indication information is located; or, they can be understood as the frequency domain resources corresponding to the first indication information in the first transmission resource; or, they can be understood as the frequency domain resources carrying the first indication information in the first transmission resource. For example, a network device configures two first transmission resources for a terminal device. The frequency domain resources corresponding to the two first transmission resources are different, and the two first transmission resources are associated with two sub-bands. The first indication information transmitted on sub-band 1 indicates that there is no transmission on the second transmission resource, and the first indication information transmitted on sub-band 2 indicates that the first DCI is transmitted on the second transmission resource.
[0199] For example, the sequence length corresponding to the sequence indicates at least the content transmitted on the second transmission resource. There is an association or correspondence between the sequence length and the transmitted content, which is determined based on protocol predefined information or network configuration information. For instance, a network device configures two first transmission resources for a terminal device, transmitting one sequence on each first transmission resource. The sequence length corresponding to sequence 1 indicates that there is no transmission on the second transmission resource, and the sequence length corresponding to sequence 2 indicates that a first DCI is transmitted on the second transmission resource.
[0200] For example, the transmission content on the second transmission resource is indicated based on the combination of the sequence index corresponding to the sequence and the frequency domain resource corresponding to the first indication information. There is an association or correspondence between the sequence index corresponding to the sequence, the frequency domain resource corresponding to the first indication information, and the transmission content. This association or correspondence is determined based on protocol predefined information or network configuration information. For instance, the network device configures four first transmission resources for the terminal device. The frequency domain resources corresponding to the four first transmission resources are different. For example, the sequences transmitted on the four first transmission resources are associated with four sub-bands, and each sub-band can be used to transmit a sequence carrying the first indication information. Taking the frequency domain positions arranged from top to bottom as an example, they are sub-band 0, sub-band 1, sub-band 2, and sub-band 3. Sequence 0 is transmitted on sub-band 0 and sub-band 1, indicating that there is no transmission on the second transmission resource. Sequence 1 is transmitted on sub-band 2 and sub-band 3, indicating that the first DCI is transmitted on the second transmission resource.
[0201] In this embodiment, the terminal device receives first indication information on a first transmission resource configured on the network device, and determines the transmission content on the second transmission resource through the first indication information and / or related information associated with the first indication information (at least one of the above eight types). Compared with PDCCH monitoring in related technologies, it does not require long-term monitoring or blind detection, which is beneficial for energy saving and consumption reduction of the terminal device.
[0202] Regarding the above-mentioned transmitted information two
[0203] In some embodiments, the first indication information is used at least to indicate the transmission parameters corresponding to the transmission content on the second transmission resource, including one or more pieces of first indication information used at least to indicate the transmission parameters corresponding to the transmission content on the second transmission resource. This application does not limit this.
[0204] In some embodiments, when the content transmitted on the second transmission resource is the transmission of the first DCI, the transmission parameters corresponding to the content are also the transmission parameters corresponding to the DCI, including at least one of the following: the format corresponding to the DCI; the number of bits corresponding to the DCI; the aggregation level corresponding to the DCI; the number of control channel units (CCEs) corresponding to the DCI; the number of resources corresponding to the DCI; the modulation scheme corresponding to the DCI; the code rate corresponding to the DCI; and the encoding scheme corresponding to the DCI.
[0205] In some embodiments, the first indication information is carried by a sequence or information bits. The first indication information is used at least to indicate the transmission parameters corresponding to the transmission content on the second transmission resource, and can also be understood as indicating the transmission parameters corresponding to the transmission content on the second transmission resource based on the sequence or information bits carrying the first indication information. Optionally, different sequences or different information bits indicate different transmission parameters corresponding to the transmission content on the second transmission resource.
[0206] In some embodiments, the first indication information at least indicates the transmission parameters corresponding to the transmission content on the second transmission resource; or, the related information associated with the first indication information at least indicates the transmission parameters corresponding to the transmission content on the second transmission resource; or, the combination of the first indication information and the related information associated with the first indication information at least indicates the transmission parameters corresponding to the transmission content on the second transmission resource. The related information includes at least one of the eight types of information mentioned above.
[0207] Taking the first indication information as an example, which indicates at least the transmission parameters corresponding to the transmission content (first DCI) on the second transmission resource, the first indication information is carried by a sequence or information bits, and different values of different sequences or information bits can be used to indicate the transmission parameters corresponding to the first DCI on the second transmission resource.
[0208] Taking the use of relevant information to at least indicate the transmission parameters corresponding to the transmission content (first DCI) on the second transmission resource as an example, the following examples illustrate at least nine different indication methods that can be used to indicate the transmission parameters corresponding to the first DCI on the second transmission resource, wherein the sequence is used to carry the first indication information.
[0209] Indication method A2: Based on the frequency domain resources corresponding to the first indication information, at least the transmission parameters corresponding to the first DCI on the second transmission resource are indicated;
[0210] Indication method B2: Based on the time domain resources corresponding to the first indication information, at least the transmission parameters corresponding to the first DCI on the second transmission resource are indicated;
[0211] Indication method C2: Based on the initial value corresponding to the sequence, at least the transmission parameters corresponding to the first DCI on the second transmission resource are indicated;
[0212] Indication method D2: Based on the cyclic shift value corresponding to the sequence, at least the transmission parameters corresponding to the first DCI on the second transmission resource are indicated;
[0213] Indication method E2: Based on the group number corresponding to the sequence, at least the transmission parameters corresponding to the first DCI on the second transmission resource are indicated;
[0214] Indication method F2: Based on the root sequence number within the group corresponding to the sequence, at least the transmission parameters corresponding to the first DCI on the second transmission resource are indicated;
[0215] Indication method G2: Based on the sequence length corresponding to the sequence, at least the transmission parameters corresponding to the first DCI on the second transmission resource are indicated;
[0216] Indication method H2: Based on the sequence index corresponding to the sequence, at least the transmission parameters corresponding to the first DCI on the second transmission resource are indicated;
[0217] Indication method I2: Based on a combination of at least two of the above indication methods, the transmission parameters corresponding to the first DCI on the second transmission resource are indicated.
[0218] For example, the frequency domain resources corresponding to the first indication information at least indicate the transmission parameters corresponding to the first DCI on the second transmission resource. Optionally, different frequency domain resources corresponding to the first indication information may correspond to different values, different states, or different sequences, thereby indicating different values of the transmission parameters corresponding to the first DCI on the second transmission resource. For example, the network device configures two first transmission resources for the terminal device. The frequency domain resources corresponding to the two first transmission resources are different, and the two first transmission resources are associated with two sub-bands. The first indication information transmitted on sub-band 1 indicates the DCI format corresponding to the first DCI, and the first indication information transmitted on sub-band 2 indicates the number of bits corresponding to the first DCI.
[0219] For example, the transmission parameters corresponding to the first DCI on the second transmission resource are indicated based on the combination of the sequence index corresponding to the sequence and the frequency domain resources corresponding to the first indication information. There is an association or correspondence between the sequence index corresponding to the sequence, the frequency domain resources corresponding to the first indication information, and the transmission parameters corresponding to the first DCI. This association or correspondence is determined based on protocol predefined information or network configuration information. For instance, the network device configures four first transmission resources for the terminal device. The frequency domain resources corresponding to the four first transmission resources are different. For example, the sequences transmitted on the four first transmission resources are associated with four sub-bands, and each sub-band can be used to transmit a sequence carrying the first indication information. Taking the frequency domain positions arranged from top to bottom as an example, they are sub-band 0, sub-band 1, sub-band 2, and sub-band 3. Sequence 0 is transmitted on sub-band 0 and sub-band 1, and sequence 0 indicates the aggregation level corresponding to the first DCI. Sequence 1 is transmitted on sub-band 2 and sub-band 3, and sequence 1 indicates the number of CCEs corresponding to the first DCI.
[0220] In this embodiment, the terminal device receives first indication information on a first transmission resource configured on the network device, and determines the transmission parameters corresponding to the transmission content on the second transmission resource through the first indication information and / or related information associated with the first indication information (at least one of the above eight types). Compared with PDCCH monitoring in related technologies, it does not require long-term monitoring or blind detection, which is beneficial to energy saving and consumption reduction of the terminal device.
[0221] Regarding the above-mentioned transmission information three
[0222] In some embodiments, the relationship between the first transmission resource and the second transmission resource is many-to-one, that is, multiple first transmission resources correspond to one second transmission resource, or one second transmission resource is associated with multiple first transmission resources. Optionally, the first indication information is repeatedly transmitted on at least two transmission resources, where the at least two first transmission resources are at least two of the multiple first transmission resources. By configuring at least two first transmission resources to repeatedly transmit the first indication information, this approach helps to improve the reception success rate and the reliability of the first indication information detection.
[0223] In some embodiments, the network device configures a second transmission resource to associate with multiple first transmission resources. When at least two of the multiple first transmission resources are used to repeatedly transmit the first indication information, the terminal device detects the first indication information on at least two first transmission resources and obtains the detection results of at least two first indication information. Each first transmission resource corresponds to one detection result.
[0224] Optionally, if at least two detection results correspond to the same detection result, the terminal device determines the detection result corresponding to the at least two detection results as the final detection result. Optionally, if at least two detection results correspond to different detection results, the terminal device determines the final detection result of the first indication information from the at least two detection results.
[0225] In some embodiments, at least two detection results correspond to at least two first transmission resources. Optionally, when at least two detection results have a one-to-one relationship with at least two first transmission resources, it can be understood that each of the at least two first transmission resources corresponds to one detection result, or it can be understood that the terminal device has different detection results for the first indication information on at least two first transmission resources.
[0226] In some embodiments, the terminal device determines the final detection result of the first indication information from at least two detection results, including but not limited to at least one of the following detection methods:
[0227] Detection Method 1: Based on the signal quality corresponding to at least two first transmission resources, determine the final detection result of the first indication information from at least two detection results;
[0228] Detection Method 2: Based on the peak values corresponding to the detection of at least two sequences transmitted by the first transmission resources, the final detection result of the first indication information is determined from at least two detection results, and the sequence is used to carry the first indication information;
[0229] Detection Method 3: Based on the number of the same detection results, determine the final detection result of the first indication information from at least two detection results.
[0230] The three different detection methods will be introduced separately below.
[0231] Regarding the above detection method one
[0232] In some embodiments, the terminal device measures at least two first transmission resources and determines first indication information based on the signal quality corresponding to the at least two first transmission resources. That is, based on the signal quality corresponding to the at least two first transmission resources, the final detection result of the first indication information is determined from at least two detection results.
[0233] In some embodiments, the terminal device measures the signal quality corresponding to at least two first transmission resources. Optionally, the signal quality includes at least one of the following: RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality), RSSI (Received Signal Strength Indicator), SINR (Signal-to-noise and Interference ratio), and SNR (Signal-to-noise ratio).
[0234] In some embodiments, the final detection result of the first indication information is determined from at least two detection results based on the signal quality corresponding to at least two first transmission resources. Optionally, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource with the best signal quality.
[0235] For example, a network device is configured to repeatedly transmit first indication information on two first transmission resources. The first indication information is used to indicate transmission information on the second transmission resource, such as the transmission content on the second transmission resource. The first indication information is also used to indicate whether the first DCI is transmitted on the second transmission resource. Table 3 shows a method for determining the final detection result of the first indication information based on signal quality.
[0236] Table 3
[0237] For example, referring to Table 3 above, the network device is configured to repeatedly transmit first indication information on two first transmission resources. The first indication information is used to indicate whether DCI is transmitted on the second transmission resource. Optionally, the terminal device detects the first indication information on these two first transmission resources, and the detection results are as follows: the detection result for the first first transmission resource is that there is no first DCI transmission on the second transmission resource, and the detection result for the second first transmission resource is that there is first DCI transmission on the second transmission resource. Optionally, the terminal device measures the signal quality corresponding to each of the two first transmission resources. The signal quality corresponding to the first first transmission resource is the first signal quality, and the signal quality corresponding to the second first transmission resource is the second signal quality. Optionally, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource with the best signal quality.
[0238] If the signal quality of the first signal quality is the best, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource of the first signal quality, that is, the final detection result is that there is no first DCI transmission on the second transmission resource. If the signal quality of the second signal quality is the best, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource of the second signal quality, that is, the final detection result is that there is first DCI transmission on the second transmission resource.
[0239] For example, the signal quality is the RSRP measurement result. The signal quality corresponding to the first first transmission resource is the first RSRP measurement result, and the signal quality corresponding to the second first transmission resource is the second RSRP measurement result. If the signal quality of the first signal quality is the best, that is, the first RSRP measurement result is the best, then the final detection result is that there is no first DCI transmission on the second transmission resource; if the signal quality of the second signal quality is the best, that is, the second RSRP measurement result is the best, then the final detection result is that there is first DCI transmission on the second transmission resource.
[0240] It should be noted that Table 3 above is merely an exemplary illustration of the final detection result for determining the first indication information based on signal quality. The method implemented in this application is not limited to the correspondence in Table 3. In some embodiments, the correspondence of network configuration only includes a portion of the content in the table above, such as only any two rows in the table above; in some embodiments, the correspondence of network configuration includes K transmission information items, and the corresponding detection results and signal quality items are also K, where K is an integer greater than or equal to 1.
[0241] Regarding the above-mentioned detection method two
[0242] In some embodiments, the first indication information is based on a sequence bearer or at least one information bit (bit sequence). The terminal device can detect the sequence through sequence correlation processing, and the peak value of the sequence detection is the maximum value of the sequence correlation processing.
[0243] In some embodiments, the terminal device measures at least two first transmission resources and determines first indication information based on the detection peak value of the sequence transmitted by the at least two first transmission resources. That is, based on the detection peak value of the sequence transmitted by the at least two first transmission resources, the final detection result of the first indication information is determined from at least two detection results. Here, the detection peak value of the sequence can be considered as the peak value corresponding to the detection of the sequence.
[0244] In some embodiments, based on the detection peak values of the sequences transmitted by at least two first transmission resources, a final detection result of the first indication information is determined from at least two detection results. The final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource with the highest detection peak value among the sequences transmitted by at least two first transmission resources. The sequence is used to carry the first indication information.
[0245] For example, a network device is configured to repeatedly transmit first indication information on two first transmission resources. The first indication information is used to indicate transmission information on the second transmission resource, such as the transmission content on the second transmission resource. The first indication information is also used to indicate whether the first DCI is transmitted on the second transmission resource. Table 4 shows a method for determining the final detection result of the first indication information based on the detection peak of the sequence.
[0246] Table 4
[0247] For example, referring to Table 4 above, the network device is configured to repeatedly transmit first indication information on two first transmission resources. The first indication information is used to indicate whether the first DCI is transmitted on the second transmission resource. Optionally, the terminal device detects the first indication information on these two first transmission resources, and the detection results are as follows: the detection result on the first first transmission resource is that there is no first DCI transmission on the second transmission resource, and the detection result on the second first transmission resource is that the first DCI is transmitted on the second transmission resource. Optionally, the terminal device measures the detection peak value of the sequence transmitted by the two first transmission resources respectively. The detection peak value of the sequence transmitted by the first first transmission resource is the first peak value, and the detection peak value of the sequence transmitted by the second first transmission resource is the second peak value. Optionally, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource with the highest detection peak value of at least two first transmission resource transmission sequences.
[0248] If the first peak value is the highest, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource of the first peak value, that is, the final detection result is that there is no first DCI transmission on the second transmission resource. If the second peak value is the highest, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource of the second peak value, that is, the final detection result is that there is first DCI transmission on the second transmission resource.
[0249] It should be noted that Table 4 above is merely an exemplary illustration of determining the final detection result of the first indication information based on the peak value of the sequence. The method implemented in this application is not limited to the correspondence in Table 4. In some embodiments, the correspondence of the 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 the network configuration includes K transmission information items, and the corresponding detection results and peak values of the sequence are also K, where K is an integer greater than or equal to 1.
[0250] Regarding the above-mentioned detection method three
[0251] In some embodiments, the terminal device measures at least two first transmission resources and determines first indication information based on the number of identical detection results, that is, based on the number of identical detection results, determines the final detection result of the first indication information among at least two detection results.
[0252] In some embodiments, the terminal device measures at least two first transmission resources, that is, the terminal device measures the first indication information transmitted on at least two first transmission resources. Optionally, the terminal device detects N possible results for the first indication information on the at least two first transmission resources, where N is a positive integer greater than or equal to 1. If N is 1, the detection result of the first indication information on the at least two first transmission resources is one detection result, and the final detection result is that detection result. If N is greater than 1, the detection result of the first indication information on the at least two first transmission resources is multiple detection results, and the final detection result is the same detection result that appears most frequently among the multiple detection results.
[0253] In some embodiments, the same detection result means that the first transmission resources in at least two first transmission resources correspond to the same detection result. It can also be understood that the detection result of the terminal device for the first indication information on at least two first transmission resources is the same detection result. It can also be understood that the detection result corresponding to the first transmission resources in at least two first transmission resources is the same. It can also be understood that the detection result of the terminal device for the first indication information on at least two first transmission resources is the same detection result.
[0254] In some embodiments, the final detection result of the first indication information is determined from at least two detection results based on the number of identical detection results. The final detection result of the first indication information is the identical detection result that appears most frequently among the at least two detection results.
[0255] For example, a network device is configured to repeatedly transmit first indication information on three first transmission resources. The first indication information is used to indicate transmission information on second transmission resources. For instance, the transmission information is the content transmitted on the second transmission resource, and the first indication information is used to indicate whether a first DCI is transmitted on the second transmission resource. Table 5 shows a method for determining the final detection result of the first indication information based on the number of identical detection results.
[0256] Table 5
[0257] For example, referring to Table 5 above, the network device is configured to repeatedly transmit the first indication information on three first transmission resources. The first indication information is used to indicate whether the first DCI is transmitted on the second transmission resource. Optionally, the terminal device detects the first indication information on these two first transmission resources, and the detection results are as follows: the detection result on the first first transmission resource is that there is no first DCI transmission on the second transmission resource; the detection result on the second first transmission resource is that there is no first DCI transmission on the second transmission resource; and the detection result on the third first transmission resource is that there is first DCI transmission on the second transmission resource.
[0258] Optionally, the terminal device determines the number of identical detection results in each of the three first transmission resources. Specifically, no first DCI transmission on the second transmission resource is considered a first detection result, and first DCI transmission on the second transmission resource is considered a second detection result. The number of first detection results is 2, meaning there are 2 instances of no first DCI transmission on the second transmission resource; the number of second detection results is 1, meaning there is 1 instance of first DCI transmission on the second transmission resource. Optionally, the final detection result of the first indication information is the identical detection result with the highest frequency among at least two detection results. That is, the final detection result of the first indication information is no first DCI transmission on the second transmission resource.
[0259] It should be noted that Table 5 above is merely an exemplary illustration of determining the final detection result of the first indication information based on the number of the same detection result. The method implemented in this application is not limited to the correspondence in Table 5. In some embodiments, the correspondence of the 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 the network configuration includes K transmission information items, and the corresponding detection results and the number of detection results are also K, where K is an integer greater than or equal to 1.
[0260] In this embodiment, the network device configures at least two first transmission resources to repeatedly transmit the first indication information, thereby achieving repeated transmission of the first indication information. By repeatedly receiving the first indication information on at least two first transmission resources, the terminal device can improve the reliability and success rate of first indication information detection.
[0261] The first DCI transmitted on the second transmission resource is described below.
[0262] In some embodiments, the terminal device obtains first indication information on a first transmission resource, the first indication information being used to indicate relevant information of a first DCI on a second transmission resource. Optionally, the second transmission resource is used to transmit the first DCI.
[0263] In some embodiments, the first DCI is carried via PDCCH; or, the first DCI is carried via PDSCH.
[0264] In some embodiments, the terminal device receives second configuration information sent by the network device. The second configuration information is used to configure indication information corresponding to the first DCI, and the indication information corresponding to the first DCI is used to indicate the transmission parameters related to the first DCI transmitted on the second transmission resource. Optionally, the second configuration information and the first configuration information described above are the same configuration information, or the second configuration information and the first configuration information described above are different configuration information; this application does not limit this.
[0265] The indication information corresponding to the first DCI is the first information.
[0266] In some embodiments, when the first DCI is carried by the PDCCH, the indication information corresponding to the first DCI is first information, which is used to indicate the transmission parameters related to the first DCI transmitted on the second transmission resource.
[0267] Optionally, the first information includes at least one of the following: format indication information corresponding to the first DCI; bit count indication information corresponding to the first DCI; aggregation level indication information corresponding to the first DCI; CCE quantity indication information corresponding to the first DCI; resource quantity indication information corresponding to the first DCI; first identifier indication information; demodulation reference signal (DMRS) indication information corresponding to the first DCI; spatial filter indication information associated with the first DCI; encoding indication information corresponding to the first DCI; and modulation scheme indication information corresponding to the first DCI.
[0268] In some embodiments, the second configuration information is further used to configure at least one indication information to have an association with the first information (the indication information corresponding to the first DCI). The at least one indication information includes at least one of the following:
[0269] • First transmission resource indication information, which is used to indicate the resource information of the first transmission resource;
[0270] • Second transmission resource indication information, which is used to indicate the resource information of the second transmission resource;
[0271] • Sequence indication information, which is used to determine the sequence transmitted on the first transmission resource, the sequence is used to carry first indication information, and the first indication information is used to indicate the transmission information of the second transmission resource.
[0272] In some embodiments, the association between at least one indication information and the first information includes at least one of the following:
[0273] • The first transmission resource indication information is associated with the first information;
[0274] • The second transmission resource indication information is associated with the first information;
[0275] • The sequence indication information is associated with the first information;
[0276] • First transmission resource indication information or sequence indication information, associated with the first information;
[0277] • The second transmission resource indication information or sequence indication information is associated with the first information.
[0278] The aforementioned relationships include one-to-one, one-to-many, many-to-one, and many-to-many relationships. This application does not limit these relationships.
[0279] In this embodiment, the second configuration information can be used to configure the association between at least one indication information and the first information (the indication information corresponding to the first DCI). By flexibly configuring the association between the two types of indication information, the network device can reduce the number of signaling messages that need to be transmitted separately and improve resource utilization efficiency. Relative to the terminal device, the terminal device receives the second configuration information sent by the network device, and through the association between the two types of indication information in the second configuration information, determines the implicit indication information based on this association during subsequent transmission, thereby reducing the number of control signaling messages required during subsequent transmission.
[0280] 1) The first information includes the format indication information corresponding to the first DCI.
[0281] In some embodiments, the first information includes format indication information corresponding to the first DCI, which is used to determine the DCI format corresponding to the first DCI on the second transport resource.
[0282] In some embodiments, the first DCI transmitted on the second transmission resource includes at least one DCI format. If the first indication information transmitted on the first transmission resource indicates that the first DCI is transmitted on the second transmission resource, the terminal device performs first DCI detection on the second transmission resource based on the configured DCI format.
[0283] In some embodiments, the network device sends second configuration information to the terminal device. The second configuration information includes format indication information for configuring the first DCI. The terminal device determines the DCI format corresponding to the first DCI based on the format indication information corresponding to the first DCI.
[0284] In some embodiments, the second configuration information sent by the network device includes index information and an association between the network device configuration index information and the DCI format corresponding to the first DCI. The terminal device can determine the DCI format corresponding to the first DCI based on the index information and the association. For example, there is an association between index information 1 and DCI format 1, and an association between index information 2 and DCI format 2. The terminal device can determine the DCI format corresponding to the first DCI based on index information 1 and index information 2.
[0285] In some embodiments, the network device configures at least one of the following indication information in the second configuration information: first transmission resource indication information, second transmission resource indication information, and sequence indication information, which has an association relationship with the format indication information corresponding to the first DCI. This association relationship can also be called a correspondence relationship. Optionally, the association relationship includes a one-to-one relationship; a one-to-many relationship; a many-to-one relationship; or a many-to-many relationship. The second configuration information and the first configuration information mentioned above (the first configuration information is used to configure the association relationship between the first and second transmission resources) can be the same configuration information.
[0286] Optionally, the second configuration information configures the association between the first transmission resource indication information / second transmission resource indication information and the format indication information corresponding to the first DCI. That is, it configures the first transmission resource to be associated with the DCI format corresponding to the first DCI, or configures the second transmission resource to be associated with the DCI format corresponding to the first DCI. For example, the terminal device detects the first indication information on the first transmission resource, and this first indication information indicates that the first DCI is transmitted on the second transmission resource. The terminal device determines the associated first DCI format based on the first or second transmission resource, and detects the first DCI on the second transmission resource based on the first DCI format.
[0287] Optionally, the first configuration information configures the association between sequence indication information and format indication information corresponding to the first DCI; that is, it configures the sequence to be associated with the DCI format corresponding to the first DCI. Optionally, the sequence is determined based on the sequence indication information. For example, the sequence is determined to be a first sequence based on the sequence indication information. When the terminal device detects the first sequence on the first transmission resource, the terminal device determines the corresponding first DCI format based on the first sequence, and detects the first DCI on the second transmission resource based on the first DCI format.
[0288] Optionally, the first configuration information configures the association between the first transmission resource indication information / second transmission resource indication information, the sequence indication information, and the format indication information corresponding to the first DCI; that is, it configures the association between the first transmission resource / second transmission resource, the sequence, and the DCI format corresponding to the first DCI. Alternatively, the first configuration information configures the first transmission resource indication information / second transmission resource indication information and the sequence indication information, and associates them with the format indication information corresponding to the first DCI. Optionally, the first transmission resource / second transmission resource is determined based on the first transmission resource indication information / second transmission resource indication information, and the sequence is determined based on the sequence indication information.
[0289] For example, the sequence is determined as the first sequence based on sequence indication information. M1 first transmission resources / second transmission resources are associated with N1 first sequences, N2 first sequences are associated with the DCI formats corresponding to P1 first DCIs, and M2 first transmission resources / second transmission resources are associated with the DCI formats corresponding to P2 first DCIs. Wherein, M1, M2, N1, N2, P1, and P2 are integers greater than or equal to 1.
[0290] For example, M1=1, N1=1, N2=1, P1=1, meaning a first transmission resource is associated with a first sequence, and a first sequence is associated with a DCI format. The terminal device detects the first sequence carrying first indication information on the first transmission resource, determines the corresponding first DCI format based on the first transmission resource or the first sequence, and detects the first DCI on the second transmission resource based on the first DCI format.
[0291] For example, M1=1, N1=2, N2=1, P1=1, meaning one first transmission resource is associated with two first sequences, and one first sequence is associated with one DCI format. If the terminal device detects a first first sequence carrying first indication information on the first transmission resource, it determines the corresponding first DCI format based on the first first sequence. The terminal device then detects the first DCI on the second transmission resource based on the first DCI format. If the terminal device detects a second first sequence carrying first indication information on the first transmission resource, it determines the corresponding second DCI format based on the second first sequence. The terminal device then detects the first DCI on the second transmission resource based on the second DCI format.
[0292] For example, M1=1, N1=1, N2=1, P1=2, meaning one first transmission resource is associated with one first sequence, and one first sequence is associated with two DCI formats, denoted as the first DCI format and the second DCI format. If the terminal device detects a first sequence carrying first indication information on the first transmission resource, it determines the corresponding first DCI format and second DCI format based on the first sequence. The terminal device then detects the first DCI on the second transmission resource based on the first DCI format and the second DCI format.
[0293] 2) The first information includes the bit count indication information corresponding to the first DCI.
[0294] In some embodiments, the first information includes bit count indication information corresponding to the first DCI, which is used to determine the number of bits contained in the first DCI transmitted on the second transmission resource. The number of bits contained in the first DCI refers to the number of information bits contained in the first DCI, or it can be considered as the total number of effective bits contained in the first DCI, or the total number of bits contained in the first DCI.
[0295] Optionally, the first DCI includes multiple information fields, or in other words, the first DCI includes multiple fields. Each information field can be used to carry different types of control information. The terminal device detects the first DCI based on the number of bits included in the first DCI. If the number of bits included in the first DCI is different, the terminal device needs to perform the first DCI detection separately.
[0296] In some embodiments, the network device sends second configuration information to the terminal device. The second configuration information includes bit count indication information for configuring the first DCI. The terminal device determines the number of bits contained in the first DCI (or the number of bits corresponding to the first DCI) based on the bit count indication information corresponding to the first DCI.
[0297] In some embodiments, the second configuration information sent by the network device includes index information and an association between the network device configuration index information and the number of bits corresponding to the first DCI. The terminal device can determine the number of bits corresponding to the first DCI based on the index information and the association. For example, index information 1 is associated with the first number of bits (e.g., 2 bits), and index information 2 is associated with the second number of bits (e.g., 4 bits). The terminal device can determine the number of bits corresponding to the first DCI based on index information 1 and index information 2.
[0298] In some embodiments, the network device configures at least one of the following indication information in the second configuration information: first transmission resource indication information, second transmission resource indication information, and sequence indication information, which is associated with the bit count indication information corresponding to the first DCI. This association relationship can also be called a correspondence relationship. Optionally, the association relationship includes a one-to-one relationship; a one-to-many relationship; a many-to-one relationship; or a many-to-many relationship. The second configuration information and the first configuration information mentioned above (the first configuration information is used to configure the association relationship between the first and second transmission resources) can be the same configuration information.
[0299] It should be noted that the relationship between configuring at least one of the first transmission resource indication information, the second transmission resource indication information, and the sequence indication information, and the bit number indication information corresponding to the first DCI is implemented in a similar way to "1) the first information includes the format indication information corresponding to the first DCI" above, and will not be repeated here.
[0300] 3) The first information includes the aggregation level indication information corresponding to the first DCI.
[0301] In some embodiments, the first information includes aggregation level indication information corresponding to the first DCI, which is used to determine the aggregation level corresponding to the first DCI transmitted on the second transport resource.
[0302] The transmission resources of the Physical Downlink Control Channel (PDCCH) include one or more CCEs. The number of CCEs is the aggregation level. Different numbers of CCEs correspond to different aggregation levels. Optionally, the aggregation level can be one of {1, 2, 4, 8, 16}.
[0303] Optionally, the first DCI transmitted on the second transmission resource corresponds to at least one aggregation level. If the first indication information transmitted on the first transmission resource indicates that the first DCI is transmitted on the second transmission resource, the terminal device performs first DCI detection on the second transmission resource based on the aggregation level corresponding to the configured first DCI.
[0304] In some embodiments, the network device sends second configuration information to the terminal device. The second configuration information includes aggregation level indication information for configuring the first DCI. The terminal device determines the aggregation level corresponding to the first DCI based on the aggregation level indication information corresponding to the first DCI.
[0305] In some embodiments, the second configuration information sent by the network device includes index information and the association between the network device configuration index information and the aggregation level corresponding to the first DCI. The terminal device can determine the aggregation level corresponding to the first DCI based on the index information and the association. For example, index information 1 is associated with the first aggregation level (e.g., aggregation level is 1), and index information 2 is associated with the second aggregation level (e.g., aggregation level is 4). The terminal device can determine the aggregation level corresponding to the first DCI based on index information 1 and index information 2.
[0306] In some embodiments, the network device configures at least one of the following indication information in the second configuration information: first transmission resource indication information, second transmission resource indication information, and sequence indication information, which is associated with the aggregation level indication information corresponding to the first DCI. This association relationship can also be referred to as a correspondence relationship. Optionally, the association relationship includes a one-to-one relationship; a one-to-many relationship; a many-to-one relationship; or a many-to-many relationship. The second configuration information and the first configuration information mentioned above (the first configuration information is used to configure the association relationship between the first and second transmission resources) can be the same configuration information.
[0307] It should be noted that the relationship between the configuration of at least one of the first transmission resource indication information, the second transmission resource indication information, and the sequence indication information and the aggregation level indication information corresponding to the first DCI is implemented in a similar way to the above "1) the first information includes the format indication information corresponding to the first DCI", and will not be repeated here.

[0309] In some embodiments, the first information includes CCE quantity indication information corresponding to the first DCI, which is used to determine the number of CCEs corresponding to the first DCI transmitted on the second transmission resource.
[0310] The transmission resources of the Physical Downlink Control Channel (PDCCH) include one or more Control Cell Equipment (CCEs). Optionally, a CCE is a resource unit used by the PDCCH to transmit downlink control information. Optionally, the transmission reliability varies depending on the number of CCEs occupied by the PDCCH; for example, the more CCEs the PDCCH occupies, the higher its transmission reliability. Occupying more CCEs provides more redundancy and fault tolerance mechanisms, thereby enhancing the reliability of the PDCCH and reducing the probability of transmission errors.
[0311] In some embodiments, the second configuration information sent by the network device includes index information, which establishes an association between the network device's configuration index information and the number of CCEs corresponding to the first DCI. The terminal device can determine the number of CCEs corresponding to the first DCI based on the index information and the association. For example, index information 1 is associated with the number of the first CCEs (e.g., 1 CCE), and index information 2 is associated with the number of the second CCEs (e.g., 4 CCEs). The terminal device can determine the number of CCEs corresponding to the first DCI based on index information 1 and index information 2.

Resource quantity 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, resource quantity includes the amount of time-domain resources and / or frequency-domain resources; for example, resource quantity includes the number of subcarriers and / or OFDM symbols.

[0367] In some embodiments, the network device configures at least one of the following indication information in the second configuration information: first transmission resource indication information, second transmission resource indication information, and sequence indication information, which is associated with the modulation scheme indication information corresponding to the PDSCH. This association relationship can also be referred to as a correspondence relationship. Optionally, the association relationship includes a one-to-one relationship; a one-to-many relationship; a many-to-one relationship; or a many-to-many relationship. The second configuration information and the first configuration information mentioned above (the first configuration information is used to configure the association relationship between the first and second transmission resources) can be the same configuration information.
[0368] Optionally, the second configuration information configures the association between the first transmission resource indication information / second transmission resource indication information and the modulation scheme indication information corresponding to the PDSCH. That is, it configures the first transmission resource to be associated with the modulation scheme corresponding to the PDSCH, or configures the second transmission resource to be associated with the modulation scheme corresponding to the PDSCH. For example, the terminal device detects the first indication information on the first transmission resource, and this first indication information indicates that the first DCI is transmitted on the second transmission resource. The terminal device determines the modulation scheme corresponding to the associated PDSCH based on the first or second transmission resource, for example, the modulation scheme is QPSK. The terminal device detects the first DCI (or downlink data) on the second transmission resource based on the QPSK modulation scheme.
[0369] Optionally, the first configuration information configures the association between sequence indication information and modulation scheme indication information corresponding to PDSCH; that is, it configures the sequence to be associated with the modulation scheme corresponding to PDSCH. Optionally, the sequence is determined based on the sequence indication information. For example, the sequence is determined as a first sequence based on the sequence indication information. When the terminal device detects the first sequence on the first transmission resource, the terminal device determines the modulation scheme corresponding to the PDSCH associated with it based on the first sequence, for example, the modulation scheme is 16QAM. The terminal device detects the first DCI (or downlink data) on the second transmission resource based on the 16QAM modulation scheme.
[0370] Optionally, the first configuration information configures the association between the first transmission resource indication information / second transmission resource indication information, the sequence indication information, and the modulation scheme indication information corresponding to the PDSCH; that is, it configures the first transmission resource / second transmission resource, the sequence, and the modulation scheme corresponding to the PDSCH to be associated. Alternatively, the first configuration information configures the first transmission resource indication information / second transmission resource indication information and the sequence indication information, and associates them with the modulation scheme indication information corresponding to the PDSCH. Optionally, the first transmission resource / second transmission resource is determined based on the first transmission resource indication information / second transmission resource indication information, and the sequence is determined based on the sequence indication information.
[0371] For example, the sequence is determined as the first sequence based on sequence indication information. M1 first transmission resources / second transmission resources are associated with N1 first sequences, N2 first sequences are associated with P1 DCI formats, and M2 first transmission resources / second transmission resources are associated with P2 DCI formats. Wherein, M1, M2, N1, N2, P1, and P2 are integers greater than or equal to 1.
[0372] For example, M1=1, N1=1, N2=1, P1=1, meaning that a first transmission resource is associated with a first sequence, and a first sequence is associated with a modulation scheme. The terminal device detects the first sequence carrying the first indication information on the first transmission resource, determines the corresponding modulation scheme based on the first transmission resource or the first sequence, and detects the first DCI on the second transmission resource based on the modulation scheme corresponding to the PDSCH.
[0373] For example, M1=1, N1=2, N2=1, P1=1, meaning one first transmission resource is associated with two first sequences, and one first sequence is associated with one modulation scheme. If the terminal device detects the first first sequence carrying the first indication information on the first transmission resource, it determines the corresponding first modulation scheme based on the first first sequence. The terminal device then detects the first DCI on the second transmission resource based on the first modulation scheme. If the terminal device detects the second first sequence carrying the first indication information on the first transmission resource, it determines the corresponding second modulation scheme based on the second first sequence. The terminal device then detects the first DCI on the second transmission resource based on the second modulation scheme.
[0374] For example, M1=1, N1=1, N2=1, P1=2, meaning one first transmission resource is associated with one first sequence, and one first sequence is associated with two modulation schemes, denoted as the first modulation scheme and the second modulation scheme. If the terminal device detects a first sequence carrying first indication information on the first transmission resource, it determines the corresponding first modulation scheme and second modulation scheme based on the first sequence. The terminal device then detects the first DCI on the second transmission resource based on the first modulation scheme and the second modulation scheme.
[0375] 2) The second information includes the MCS level indication information corresponding to the PDSCH.
[0376] In some embodiments, the second information includes MCS level indication information corresponding to the PDSCH. The MCS level indication information is used to determine the MCS level corresponding to the PDSCH transmitted on the second transmission resource. The MCS level can also be called an MCS index. The MCS index is a specific representation of the MCS level. Each MCS level corresponds to a specific set of modulation schemes and coding rates, used to select appropriate transmission parameters based on channel quality.
[0377] In some embodiments, the PDSCH transmitted on the second transport resource corresponds to at least one MCS level. The terminal device detects the first DCI (or downlink data) on the second transport resource based on the configured MCS level corresponding to the PDSCH.
[0378] In some embodiments, the network device sends second configuration information to the terminal device. The second configuration information includes MCS level indication information for configuring the PDSCH. The terminal device determines the MCS level corresponding to the PDSCH based on the MCS level indication information corresponding to the PDSCH.
[0379] In some embodiments, the network device configures at least one of the following indication information in the second configuration information: first transmission resource indication information, second transmission resource indication information, and sequence indication information, which is associated with the MCS level indication information corresponding to the PDSCH. This association relationship can also be referred to as a correspondence relationship. Optionally, the association relationship includes a one-to-one relationship; a one-to-many relationship; a many-to-one relationship; or a many-to-many relationship. The second configuration information and the first configuration information mentioned above (the first configuration information is used to configure the association relationship between the first and second transmission resources) can be the same configuration information.
[0380] The following explanation uses the association between the sequence indication information configured in the second configuration information and the MCS level indication information corresponding to the PDSCH as an example. The sequence indication information and the MCS level indication information corresponding to the PDSCH are associated; this can also be understood as the first transmission resource being associated with the MCS level. For example, the sequence is determined as the first sequence based on the sequence indication information. When the terminal device detects the first sequence on the first transmission resource, this first sequence carries first indication information, which indicates that the PDSCH is transmitted on the second transmission resource. The terminal device determines the corresponding MCS level based on this first sequence, for example, MCS level 12. The terminal device detects the first DCI on the second transmission resource based on MCS level 12.
[0381] It should be noted that the relationship between configuring at least one of the first transmission resource indication information, the second transmission resource indication information, and the sequence indication information and the MCS level indication information corresponding to the PDSCH is implemented in a similar way to "1) the second information includes the modulation scheme indication information corresponding to the PDSCH" above, and will not be repeated here.
[0382] 3) The second information includes the MCS table indication information corresponding to the PDSCH.
[0383] In some embodiments, the second information includes MCS table indication information corresponding to the PDSCH, which is used to determine the MCS table corresponding to the PDSCH transmitted on the second transport resource. The MCS table includes 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.
[0384] 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 contains MCS schemes with lower modulation order and lower coding rate. The modulation order refers to the order of the modulation scheme, used to indicate the number of bits in the modulated data signal.
[0385] In some embodiments, the PDSCH transmitted on the second transport resource corresponds to at least one MCS table. The terminal device detects the first DCI (or downlink data) on the second transport resource based on the configured MCS table corresponding to the PDSCH.
[0386] In some embodiments, the network device configures at least one of the following indication information in the second configuration information: first transmission resource indication information, second transmission resource indication information, and sequence indication information, which is associated with the MCS table indication information corresponding to the PDSCH. This association relationship can also be referred to as a correspondence relationship. Optionally, the association relationship includes a one-to-one relationship; a one-to-many relationship; a many-to-one relationship; or a many-to-many relationship.

[0394] In some embodiments, the second information includes coding rate indication information corresponding to the PDSCH, which is used to determine the coding rate corresponding to the PDSCH transmitted on the second transmission resource.
[0395] Encoding rate refers to the ratio of the original data volume to the encoded data volume in data transmission. In other words, the encoding rate is the ratio of the effective data bits after encoding to the total number of transmitted bits, reflecting the effectiveness of the encoded information relative to the total transmitted information.
[0396] In some embodiments, the network device sends second configuration information to the terminal device, the second configuration information including coding rate indication information corresponding to the PDSCH, and the terminal device detects the first DCI (or downlink data) on the second transmission resource based on the coding rate corresponding to the configured PDSCH.

If the first indication information indicates that a first DCI is being transmitted on the second transmission resource, the network device transmits the first DCI on the second transmission resource. The first DCI is used to indicate information related to a second DCI on a third transmission resource.

[0518] In some embodiments, the network device transmits a first DCI on a second transmission resource, which may also be referred to as a first-order DCI, and the network device transmits a second DCI on a third transmission resource, which may also be referred to as a second-order DCI.

The first DCI is used not only to indicate relevant information of the second DCI, such as transmission parameters and / or transmission resources, but also to indicate a first portion of the information in the PDSCH or PUSCH transmission, while the second DCI indicates another portion of the information. For example, referring to FIG8, the acquisition module 1110 acquires first indication information on the first transmission resource. The first indication information indicates the first DCI on the second transmission resource, and the first DCI is used to indicate the second DCI on the third transmission resource. The first DCI and the second DCI jointly schedule PDSCH or PUSCH transmissions. The first DCI is also used to indicate a portion of the information in the PDSCH or PUSCH transmission on the fourth transmission resource, while the second DCI indicates another portion of the information in the PDSCH or PUSCH transmission on the fourth transmission resource.

The first DCI is used to indicate relevant information (or scheduling information, authorization information) of the second DCI, and the second DCI is used to indicate relevant information (or scheduling information, authorization information) of PDSCH or PUSCH transmissions. For example, referring to FIG9, the acquisition module 1110 acquires first indication information on the first transmission resource. The first indication information indicates the first DCI on the second transmission resource, and the first DCI is used to indicate the second DCI on the third transmission resource. The second DCI is used to schedule PDSCH or PUSCH transmissions; for example, the second DCI is used to indicate the transmission parameters of PDSCH or PUSCH transmissions on the fourth transmission resource.

[0525] In summary, the method provided in this application embodiment allows the transmission device to obtain first indication information on the first transmission resource. By detecting the first indication information on the first transmission resource, it can determine whether it is necessary to detect the first DCI (also known as the first-order DCI) on the second transmission resource based on the first indication information. Then, it can confirm the relevant information of the second DCI (also known as the second-order DCI) based on the first DCI. This method schedules PDSCH or PUSCH transmission through two-order DCI. This tiered scheduling method can reduce the complexity of DCI detection.
[0526] Furthermore, for each group of transmission resources, only the first indication information on the first transmission resource needs to be detected. Based on the first indication information, the transmission behavior on subsequent transmission resources is determined. Compared with blind detection in related technologies, blind detection is not required or its complexity is reduced, achieving the effect of energy saving and consumption reduction.

Then, it confirms the relevant information of the second DCI (also known as the second-order DCI) based on the first DCI. This method schedules PDSCH or PUSCH transmission through two-order DCI. This tiered scheduling method can reduce the complexity of DCI detection.
[0544] Furthermore, for each group of transmission resources, only the first indication information on the first transmission resource needs to be detected. Based on the first indication information, the transmission behavior on subsequent transmission resources is determined. Compared with blind detection in related technologies, blind detection is not required or its complexity is reduced, achieving the effect of energy saving and consumption reduction.
