Detailed implementation manners

Apparently, the described embodiments are some, but not all, of the embodiments of this application.

[0045] To illustrate the present application more clearly, the related technologies involved in the present application are introduced below.
[0046] The terminal can receive the PDSCH based on the DCI in the PDCCH. Specifically, the terminal can look up the (m + 1)-th row of the TDRA table based on the value m of the Time Domain Resource Assignment (TDRA) field in the DCI to obtain the time domain resources of the PDSCH, and receive the PDSCH on the corresponding time domain resources.
[0047] The TDRA table includes the slot offset K0 between the PDSCH and the PDCCH (which can also be referred to as the slot offset between the PDSCH and the DCI), the start symbol of the PDSCH, and the Start and Length Indicator Value (SLIV) (or directly represented by the start symbol S and the allocated length L), and the PDSCH mapping type.
[0048] Exemplarily, the TDRA table can be as shown in Table 1.

[0050] Index K0 Mapping type SLIV 0 0 A 58 1 1 A 56 2 4 B c 3 6 A d … … … … 15 32 B p
[0051] When the index is 0, the time domain position of the PDSCH scheduled by the PDCCH can be as Figure 1 shown; when the index is 1, the time domain position of the PDSCH scheduled by the PDCCH can be as Figure 2 shown.
[0052] To facilitate understanding, the communication system architecture of the embodiments of the present application is described below.
[0053] Figure 3 It is a schematic diagram of an architecture of the communication system provided by the embodiments of the present application. As Figure 3 shown, the architecture includes a network device 301 and a terminal 302.
[0054] The network device in this application is a device with wireless transceiver functions, including but not limited to: evolved Node B (eNB or eNodeB) in Long Term Evolution (LTE), gNodeB or gNB or multi-transmission and receiving points (M-TRP) in New Radio (NR), base stations in subsequent evolved systems, access nodes in Wireless Fidelity (WiFi) systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: macro base station, micro base station, pico base station, small cell, relay station, or balloon station, etc. Multiple base stations can support the networks of the same technology mentioned above, or can support the networks of different technologies mentioned above. The base station can include one or more co-located or non-co-located TRPs.
[0055] The terminal in this application is a device with wireless transceiver functions. The terminal can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water (such as on a ship, etc.); it can also be deployed in the air (such as on an airplane, balloon, satellite, etc.). The terminal can be a mobile phone, tablet (Pad), computer with wireless transceiver functions, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, vehicle-mounted terminal device, wireless terminal in self-driving, wireless terminal device in remote medical, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, wireless terminal device in smart home, wearable terminal device, etc. The terminal involved in the embodiments of this application can also be referred to as user equipment (UE), access terminal, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile terminal, remote station, remote user equipment, mobile device, wireless communication device, UE agent or UE device, etc. The terminal can also be fixed or mobile.
[0056] In the 52.6GHz access technology of the 3rd Generation Partnership Project (3GPP) standard, a scheduling method that supports a maximum of 8 PDSCHs scheduled by one DCI can be implemented by configuring the TDRA table. Specifically, the higher layer configures a maximum of 8 TDRA tables, and each table corresponds to one PDSCH. Since each PDSCH has an independent TDRA table, K0 can be configured with different values, which means that the PDSCHs can be discontinuous in time slots.
[0057] For terahertz (THz), a 1920KHz subcarrier spacing (SCS) may be introduced. If the scheduling method of a maximum of 8 PDSCHs at 52.6GHz is continued to be used, it will lead to an increase in the power consumption of PDCCH monitoring and an increase in the requirements for PDCCH decoding capabilities.
[0058] To solve the above technical problems, the present application provides a communication method. By sending PDSCHs in a bound group manner, the number of PDSCHs that can be scheduled by a single DCI is increased, thereby reducing the complexity of PDCCH monitoring, and further reducing the power consumption of PDCCH monitoring and the requirements for PDCCH decoding capabilities.
[0059] Next, the technical solutions shown in the present application will be described in detail through specific embodiments. It should be noted that the following several embodiments can exist independently or be combined with each other. For the same or obvious content, it will not be repeated in different embodiments.
[0060] Figure 4 It is a schematic flowchart of a communication method provided by an embodiment of the present application. Please refer to Figure 4 The method includes:
[0061] S401. The network device sends a DCI to the terminal. The DCI is used to schedule multiple PDSCHs. The DCI includes indication information, and the indication information is used to indicate that the multiple PDSCHs are sent in a bound group manner and indicate the number of PDSCHs in the bound group.
[0062] In other words, the terminal receives the DCI sent by the network device.
[0063] The DCI is carried on the PDCCH.
[0064] Exemplarily, if the indication information is indicated by 2 bits, when the values of the 2 bits are 00, it may indicate that multiple PDSCHs are transmitted in an unbound manner; when the values of the 2 bits are 01, it may indicate that multiple PDSCHs are transmitted in a bound group manner, and the number of PDSCHs in the bound group is 2; when the values of the 2 bits are 10, it may indicate that multiple PDSCHs are transmitted in a bound group manner, and the number of PDSCHs in the bound group is 3; when the values of the 2 bits are 11, it may indicate that multiple PDSCHs are transmitted in a bound group manner, and the number of PDSCHs in the bound group is 4.
[0065] It should be noted that the number of bits occupied by the above indication information is only an example, and the indication information can also be indicated by other numbers of bits. The present application does not limit the number of bits occupied by the indication information.
[0066] The number of PDSCHs in each bound group can be the same.
[0067] The number of PDSCHs in the bound group can be 2, 3, 4, etc. The present application does not limit the number of PDSCHs in the bound group.
[0068] In a possible implementation manner, the number of bound groups can be indicated by DCI or determined by the number of TDRA tables.
[0069] Exemplarily, if DCI indicates that the number of bound groups is 4, and the indication information indicates that the PDSCH is transmitted in a bound group manner, and the number of PDSCHs in the bound group is 4, then the total amount of PDSCHs scheduled by DCI is 16.
[0070] In another example, if the number of TDRA tables configured by the higher layer is 2, and the indication information indicates that the PDSCH is transmitted in a bound group manner, and the number of PDSCHs in the bound group is 8, since the number of TDRA tables is the same as the number of bound groups, when the number of TDRA tables is 2, the number of bound groups is also 2. At this time, the total amount of PDSCHs scheduled by DCI is 16.
[0071] In a possible implementation manner, for any bound group, the hybrid automatic repeat request (HARQ) process identifier, redundancy version (RV), and new data indicator (NDI) of each PDSCH in the bound group are also the same.
[0072] In a possible implementation, for any binding group, one binding group corresponds to one TDRA table, that is, the SLIV and mapping type corresponding to each PDSCH within the binding group are the same. K0 is the slot offset between the first PDSCH within the binding group and the DCI, and the position of the subsequent PDSCH is obtained by adding one to the position of the previous PDSCH in terms of slots.
[0073] Exemplarily, if the number of PDSCHs within the binding group is 4, the DCI is in the first slot, and K0 is 1, then the first PDSCH within the binding group is in the second slot, the second PDSCH is in the third slot, the third PDSCH is in the fourth slot, and the fourth PDSCH is in the fifth slot.
[0074] It should be noted that the previous PDSCH and the subsequent PDSCH are two adjacent PDSCHs. For example, if there are a total of 3 PDSCHs, and their positions in the time domain are the first PDSCH, the second PDSCH, and the third PDSCH in sequence, then the first PDSCH can be the previous PDSCH of the second PDSCH, the second PDSCH can be the subsequent PDSCH of the first PDSCH, the second PDSCH can be the previous PDSCH of the third PDSCH, and the third PDSCH can be the subsequent PDSCH of the second PDSCH.
[0075] In a possible implementation, the K0 in the TDRA table corresponding to the subsequent binding group and the K0 in the TDRA table corresponding to the previous binding group satisfy the following relational expression:
[0076] K02 ≥ K01 + the number of PDSCHs within the binding group - 1
[0077] Wherein, K02 is the K0 in the TDRA table corresponding to the subsequent binding group, and K01 is the K0 in the TDRA table corresponding to the previous binding group.
[0078] It should be noted that the previous binding group and the subsequent binding group are two adjacent binding groups. For example, if there are a total of 3 binding groups, which are the first binding group, the second binding group, and the third binding group in sequence, then the first binding group can be the previous binding group of the second binding group, the second binding group can be the subsequent binding group of the first binding group, the second binding group can be the previous binding group of the third binding group, and the third binding group can be the subsequent binding group of the second binding group.
[0079] In a possible implementation, the value of K0 can be increased to 64.
[0080] When the value of K0 is increased to 64, it can provide greater flexibility for the scheduling of PDSCHs and can also increase the number of PDSCHs within each binding group.
[0081] If the network device indicates a maximum scheduling of 8 PDSCHs (existing scheduling method), the terminal can detect the PDCCH at a maximum interval of 8 time slots; if the network device indicates a maximum scheduling of 8 binding groups, and the number of PDSCHs in each binding group is 2 (scheduling method of the embodiments of the present application), the terminal can detect the PDCCH at a maximum interval of 16 time slots, greatly reducing the monitoring complexity of the PDCCH.
[0082] S402. The network device sends multiple PDSCHs to the terminal.
[0083] In other words, the terminal receives multiple PDSCHs sent by the network device based on the DCI.
[0084] After receiving the DCI, the terminal can determine the time domain position of each PDSCH based on the indication information in the DCI and the TDRA table configured by the higher layer, and then receive the PDSCH based on the time domain position of each PDSCH. The time domain position of the PDSCH can be as Figure 1 or Figure 2 shown.
[0085] In a possible implementation manner, for any binding group, the HARQ response information of the PDSCHs within the binding group can also be bound.
[0086] The binding process may refer to performing a logical AND calculation on the HARQ response information of all the PDSCHs within the binding group and feeding back the result of the logical AND calculation.
[0087] Regardless of the number of PDSCHs within the binding group, only one HARQ response information is fed back.
[0088] In Figure 4 the shown embodiment, the network device sends DCI to the terminal. The DCI is used to schedule multiple PDSCHs. The DCI includes indication information, and the indication information is used to indicate that the multiple PDSCHs are sent in a binding group manner and indicates the number of PDSCHs within the binding group. The terminal receives the multiple PDSCHs based on the received DCI. Sending the PDSCHs in a binding group method increases the number of PDSCHs that can be scheduled by a single DCI, thereby reducing the monitoring complexity of the PDCCH.
[0089] Figure 4 The shown embodiment gives a method for reducing the monitoring complexity of the PDCCH. Next, other ways for reducing the monitoring complexity of the PDCCH are given.
[0090] Method 1: The higher layer configures the number of transport blocks (TBs) and the TDRA table.
[0091] If the number of TDRA tables is 1 and the number of TBs is 16, it means that DCI can schedule up to 16 PDSCHs at most. That is, these 16 PDSCHs share one TDRA table. Among them, K0 in the TDRA table is the slot offset between the first PDSCH and DCI. The position of the subsequent PDSCH is obtained by adding 1 to the position of the previous PDSCH in the slot. The terminal can receive multiple PDSCHs scheduled by DCI based on the high-layer configuration and DCI.
[0092] In this case, the HARQ process identifiers, NDI, and RV of the 16 PDSCHs are the same, and the SLIVs and mapping types corresponding to the 16 PDSCHs are the same.
[0093] If the number of TDRA tables is 2 and the number of TBs is 8, it means that DCI can schedule up to 16 PDSCHs at most. One TDRA table can indicate the time-domain positions of 8 PDSCHs. The HARQ process identifiers, NDI, and RV of these 8 PDSCHs are the same, and the SLIVs and mapping types corresponding to the 8 PDSCHs are the same.
[0094] K0 in each TDRA table is the slot offset between the first PDSCH and DCI. The position of the subsequent PDSCH is obtained by adding 1 to the position of the previous PDSCH in the slot. The terminal can receive multiple PDSCHs scheduled by DCI based on the high-layer configuration and DCI.
[0095] Method 2: The high layer configures the TDRA table, and the number of TDRA tables is greater than eight.
[0096] Exemplarily, for THz and 1920KHz SCS, the high layer can configure 16 TDRA tables. One TDRA table corresponds to one PDSCH. At this time, DCI can schedule up to 16 PDSCHs at most. The HARQ process identifiers, NDI, and RV of these 16 PDSCHs are different from each other. The terminal can receive multiple PDSCHs scheduled by DCI based on the high-layer configuration and DCI.
[0097] Since the current NR system only supports 16 HARQs, it means that there will be a HARQ order conflict problem in subsequent multi-PDSCH scheduling. It is necessary to increase the HARQ process identifier indication field by 1 bit to extend the maximum value of the HARQ process identifier to 32.
[0098] The NDI indication field needs to be extended to 16 bits, and the RV indication field needs to be extended to 16 bits.
[0099] It should be noted that the number of bits of the above-mentioned HARQ process identification indication field, NDI indication field, and RV indication field is only an example, and the number of bits of the HARQ process identification indication field, NDI indication field, and RV indication field can be adaptively adjusted according to the number of TDRA tables configured by the upper layer.
[0100] Through the method of the present application, the number of PDSCHs that can be scheduled by a single DCI is increased, thereby reducing the monitoring complexity of the PDCCH.
