Description

[0001] This application claims the priority of a patent application filed with the China Patent Office on October 16, 2019, with application number PCT / CN2019 / 111544 and invention name “An Information Processing Method, Terminal Device and Network Device”, the entire contents of which are incorporated by reference in this application. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and in particular to an information processing method, a terminal device, and a network device. Background Art

[0003] In a communication system, one downlink control information (DCI) schedules one transport block (TB) or schedules multiple transport blocks.

[0004] When DCI schedules a TB, DCI also indicates a hybrid automatic retransmission request (HARQ) process number. For example, if the user equipment (UE) supports 8 HARQ processes, DCI uses 3 bits from 0 to 7 to indicate the HARQ process number used by the TB scheduled by the DCI. When DCI schedules a TB, DCI also indicates whether the data carried by the transport block scheduled by the DCI is new data or retransmission data.

[0005] In order to reduce the overhead of DCI transmission and save transmission resources, one DCI can be used to schedule multiple TBs. When one DCI schedules multiple transmission blocks, the DCI can indicate multiple HARQ process numbers, where each HARQ process number corresponds to or is associated with the transmission of one transmission block. In order to further reduce the overhead when one DCI schedules multiple transmission blocks, it is necessary to constrain the HARQ process numbers used by multiple transmission blocks to be continuous, and it is also necessary to fix the first HARQ process number among the multiple HARQ process numbers. For example, a DCI schedules N transmission blocks, and the HARQ process number of the first transmission block among the N transmission blocks is fixed, for example, fixed to 0, then the HARQ process numbers of the remaining N-1 transmission blocks among the N transmission blocks are 1, 2, ..., N-1.

[0006] For the case where DCI can schedule up to N transport blocks, N bits are required to indicate the new data indicator (NDI) information of each transport block in a bitmap manner, and N bits are required to indicate whether the HARQ process number of each transport block is used in a bitmap manner. In addition, 1 bit is required in DCI to distinguish between multi-TB scheduling and single-TB scheduling.

[0007] Therefore, the above solution has the problem that the DCI scheduling is not flexible enough. Summary of the invention

Or the first communication device may include: a network device, and the second communication device may include: another network device.

[0064] Figure 1 A schematic diagram of the structure of a possible radio access network (RAN) of an embodiment of the present application is shown. The RAN may be a base station access system of a 2G network (i.e., the RAN includes a base station and a base station controller), or may be a base station access system of a 3G network (i.e., the RAN includes a base station and an RNC), or may be a base station access system of a 4G network (i.e., the RAN includes an eNB and an RNC), or may be a base station access system of a 5G network.

[0065] The RAN includes one or more network devices. The network device may be any device with a wireless transceiver function, or a chip set in a device with a specific wireless transceiver function. The network device includes, but is not limited to, a base station (e.g., a base station BS, a base station NodeB, an evolved base station eNodeB or eNB, a base station gNodeB or gNB in ​​a fifth-generation 5G communication system, a base station in a future communication system, an access node in a WiFi system, a wireless relay node, a wireless backhaul node), etc. The base station may be: a macro base station, a micro base station, a micro-micro base station, a small station, a relay station, etc. Multiple base stations may support a network of one or more of the above-mentioned technologies, or a future evolution network. The core network may support a network of one or more of the above-mentioned technologies, or a future evolution network. The base station may include one or more co-sited or non-co-sited transmission receiving points (TRP). The network device may also be a wireless controller, a centralized unit (CU), or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The network device may also be a server, a wearable device, or a vehicle-mounted device. The following description is made by taking a base station as an example of a network device. The multiple network devices may be base stations of the same type or different types. The base station may communicate with the terminal devices 1-6, or may communicate with the terminal devices 1-6 through a relay station. The terminal devices 1-6 may support communication with multiple base stations of different technologies. For example, the terminal device may support communication with a base station supporting an LTE network, may support communication with a base station supporting a 5G network, and may support dual connection with a base station of an LTE network and a base station of a 5G network. For example, the terminal is connected to a RAN node of a wireless network. Currently, some examples of RAN nodes are: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), basestation controller (BSC), base transceiver station (BTS), home evolved NodeB (or home NodeB, HNB), base band unit (BBU), or wireless fidelity (Wifi) access point (AP), etc.In a network structure, the network device may include a centralized unit (CU) node, or a distributed unit (DU) node, or a RAN device including a CU node and a DU node.

[0066] The terminal device 1-6, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), terminal, etc., is a device that provides voice and / or data connectivity to a user, or a chip set in the device, for example, a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminal devices are: mobile phones, tablet computers, laptops, PDAs, mobile Internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc. The terminal device provided in the embodiments of the present application may be a low-complexity terminal device and / or a terminal device in coverage enhancement A mode.

[0067] In an embodiment of the present application, the base station and UE1 to UE6 form a communication system, in which the base station sends one or more system information, RAR messages and paging messages to one or more UEs among UE1 to UE6. In addition, UE4 to UE6 also form a communication system, in which UE5 can be implemented as the function of a base station, and UE5 can send one or more system information, control information and paging messages to one or more UEs among UE4 and UE6.

[0068] In this application, transmission can be sending or receiving. When one side of the communication is sending, the other end of the communication is receiving. TB can be a TB for uplink transmission or a TB for downlink transmission.

[0069] The i-th TB in the present invention is defined below. DCI indicates or schedules N HARQ processes, and the N HARQ process numbers are arranged in ascending order. Assume that the HARQ process numbers after the N HARQ process numbers are arranged in ascending (or descending) order are M(0), M(1), ..., M(N-1). The HARQ process number of the i-th TB is M(i-1), where i=1, ..., N.

[0070] See also Figure 2 As shown, it is a schematic diagram of an interactive process of an information processing method provided in an embodiment of the present application. The subsequent steps 201 to 206 are described from the side of the network device, and the subsequent steps 211 to 215 are described from the side of the terminal device, which mainly includes the following steps:

[0071] 201. The network device determines the number L of transmission blocks TB scheduled by downlink control information, where the downlink control information can schedule a maximum of N TBs, N and L are positive integers, and 1≤L≤N.

[0072] The downlink control information can schedule one or more TBs, for example, the number of TBs scheduled by the downlink control information is represented by the letter L. The downlink control information can schedule a maximum of N TBs, where N is a positive integer, L is a positive integer, and 1≤L≤N, and the specific value of L is not limited here.

[0073] The number L of transport blocks TB scheduled by the downlink control information may also be the number L of hybrid automatic repeat request HARQ processes indicated by the downlink control information, that is, the number of TBs and the number of HARQ processes are in one-to-one correspondence.

[0074] 202. The network device determines the HARQ process numbers of the L TBs.

[0075] In the embodiment of the present application, when the network device determines that the number of TBs scheduled by the downlink control information is L, the network device also needs to determine the HARQ process numbers of the L TBs, for example, determine the HARQ process number of each TB in the L TBs, and the HARQ process number can also be called the HARQ process index. For example, when N is equal to 4, the TBs scheduled by the downlink control information can use up to 4 process numbers, namely H0, H1, H2, and H3.

[0076] 203. The network device determines L TB of new data indication NDI information.

[0077] In the embodiment of the present application, when the network device determines that the number of TBs scheduled by the downlink control information is L, the network device also needs to determine the NDI information of the L TBs, for example, the network device needs to determine the NDI information of each TB in the L TBs. For example, the NDI information is carried in the downlink control information.

[0078] It should be noted that the NDI information indicates whether the TB scheduled by the downlink control information is a new transmission TB or a retransmission TB. For example, the NDI information may include feedback information of each TB in L TBs, where the feedback information of the TB may also be referred to as the response information of the TB.

[0079] There is no time sequence between step 202 and step 203. For example, the network device may first execute any one of step 202 to step 203, or the network device may execute step 202 to step 203 at the same time.

[0080] 204. The network device sends downlink control information to the terminal device, where the downlink control information includes a first bit, and the first bit includes 2 bits.

[0081] Among them, the bit state of the first bit belongs to the first state set, the first state set is {01, 10, 11}, N=4, and the downlink control information includes a first field, the bit state of the first bit is used to indicate the number of TBs L scheduled by the downlink control information, and the bit state of 5 bits of the first field is used to indicate the HARQ process numbers of L TBs and the NDI information of L TBs; or, the bit state of the first bit is the second state, the second state is 00, N=1, the HARQ process index indication field included in the downlink control information is used to indicate the HARQ process number of 1 TB, and the NDI field included in the downlink control information is used to indicate the NDI information of 1 TB.

[0082] The first bit includes 2 bits, and there are four bit states of the first bit: 01, 10, 11, and 00, among which 01, 10, and 11 belong to the first state set, and 00 is the second state. According to whether the bit state of the first bit belongs to the first state set or the second state, the downlink control information includes different fields, thereby realizing the indication of the HARQ process number and NDI information of each TB at different L times.

[0083] like Figure 3aAs shown, the first bit includes 2 bits. If the bit state of the first bit is 01, or 10, or 11, the bit state of the first bit belongs to the first state set. Each bit state of the first bit can correspond to a value of L. For example, the bit state of the first bit is 01, corresponding to L=2, the bit state of the first bit is 10, corresponding to L=3, and the bit state of the first bit is 11, corresponding to L=4. At this time, the downlink control information includes the first field, and the field name of the first field is not limited. The first field includes 5 bits, that is, the size of the first field can be 5 bits. The bit state of the 5 bits of the first field is used to indicate the HARQ process number of L TBs and the NDI information of L TBs. For example, 5 bits can represent 2 5 32 bit states, that is, 32 states can be used for the HARQ process number corresponding to each TB and whether each TB is a new transmission TB or a retransmission TB.

[0084] like Figure 3b As shown, the first bit includes 2 bits. If the bit state of the first bit is 00, the bit state of the first bit belongs to the second state. At this time, N=1, and the downlink control information schedules a single TB. The downlink control information may include: a HARQ process index indication field and an NDI field. The HARQ process index indication field occupies 1 bit, and the NDI field occupies 1 bit. The HARQ process index indication field is used to indicate the HARQ process number of 1 TB, and the NDI field is used to indicate the NDI information of 1 TB. In the embodiment of the present application, it is not necessary to use 1 bit alone in the downlink control information to indicate single TB scheduling or multi-TB scheduling. Therefore, when N=4, only 7 bits are needed at most to support the scheduling of any number of TBs in N TBs by a downlink control information, and any HARQ process number can be indicated for each scheduled TB, thereby improving the flexibility of scheduling and saving the bit overhead of the downlink control information.

[0085] In an embodiment of the present application, the downlink control information is capable of simultaneously scheduling new transmission TBs and retransmission TBs, wherein "capable" refers to the ability of a network device to schedule different TB types (e.g., new transmission TBs and retransmission TBs) through downlink control information. The downlink control information is capable of simultaneously scheduling new transmission TBs and retransmission TBs, but the network device can determine the type of TB actually scheduled in the downlink control information based on the type of TB that needs to be fed back.

[0086] 211. The terminal device receives downlink control information from the network device, wherein the downlink control information can schedule a maximum of N transmission blocks TB, where N is a positive integer; the downlink control information includes a first bit, and the first bit includes 2 bits.

[0087] Among them, the network device sends downlink control information to the terminal device, and the downlink control information includes a first bit, and the first bit includes 2 bits. According to different values ​​of the bit state of the first bit, the terminal device parses the downlink control information in different ways. For example, if the bit state of the first bit belongs to the first state set, the terminal device executes step 212. If the bit state of the first bit is the second state, the terminal device executes step 213.

[0088] 212. The bit state of the first bit belongs to a first state set, the first state set is {01, 10, 11}, N=4, and the downlink control information includes a first field, the first field includes 5 bits, the terminal device determines the number of TBs L scheduled by the downlink control information according to the bit state of the first bit, and the terminal device determines the hybrid automatic repeat request HARQ process number of L TBs and the new data indication NDI information of L TBs according to the bit state of the 5 bits of the first field; or,

[0089] 213. The bit state of the first bit is the second state, the second state is 00, N=1, the terminal device determines the HARQ process number of 1 TB according to the HARQ process index indication field included in the downlink control information, and determines the NDI information of 1 TB according to the NDI field included in the downlink control information.

[0090] In an embodiment of the present application, when the bit state of the first bit belongs to the first state set, step 212 can be executed, and when the bit state of the first bit is the second state, step 213 can be executed. The specific step to be executed needs to be determined based on the bit state of the first bit determined by the network device, which is not limited here.

[0091] like Figure 3a As shown, the first bit includes 2 bits. If the bit state of the first bit is 01, or 10, or 11, the bit state of the first bit belongs to the first state set. Each bit state of the first bit can correspond to a value of L. For example, the bit state of the first bit is 01, corresponding to L=2, the bit state of the first bit is 10, corresponding to L=3, and the bit state of the first bit is 11, corresponding to L=4. At this time, the downlink control information includes the first field, and the field name of the first field is not limited. The first field includes 5 bits, that is, the size of the first field can be 5 bits. The bit state of the 5 bits of the first field is used to indicate the HARQ process number of L TBs and the NDI information of L TBs. For example, 5 bits can represent 2 5 32 bit states, that is, 32 states can be used to indicate the HARQ process number corresponding to each TB and whether each TB is a new transmission TB or a retransmission TB.

[0092] like Figure 3bAs shown, the first bit includes 2 bits. If the bit state of the first bit is 00, the bit state of the first bit belongs to the second state. At this time, N=1, and the downlink control information schedules a single TB. The downlink control information may include: a HARQ process index indication field and an NDI field. The HARQ process index indication field occupies 1 bit, and the NDI field occupies 1 bit. The HARQ process index indication field is used to indicate the HARQ process number of 1 TB, and the NDI field is used to indicate the NDI information of 1 TB. In the embodiment of the present application, it is not necessary to use 1 bit alone in the downlink control information to indicate single TB scheduling or multi-TB scheduling. Therefore, when N=4, only 7 bits are needed at most to support the scheduling of any number of TBs in N TBs by a downlink control information, and any HARQ process number can be indicated for each scheduled TB, thereby improving the flexibility of scheduling and saving the bit overhead of the downlink control information.

[0093] The embodiment of the present application can be applicable to the scenario of uplink transmission or the scenario of downlink transmission. For example, in downlink transmission, the network device sends L TBs and the terminal device receives L TBs. In uplink transmission, the terminal device sends L TBs and the network device receives L TBs. In the scenario of downlink transmission of L TBs, subsequent steps 205 and 214 are performed.

[0095] 214. The terminal device receives L TBs according to the determined HARQ process number of each TB in the L TBs and the NDI information of each TB in the L TBs.

[0096] The embodiments of the present application may be applicable to scenarios of uplink transmission or downlink transmission. For example, in downlink transmission, the network device sends L TBs and the terminal device receives L TBs. In uplink transmission, the terminal device sends L TBs and the network device receives L TBs. In the scenario of uplink transmission of L TBs, subsequent steps 215 and 206 are performed.

[0097] 215. The terminal device sends L TBs according to the determined HARQ process number of each TB in the L TBs and the NDI information of each TB in the L TBs.

[0099] It can be seen from the examples of the above embodiments that the network device sends downlink control information to the terminal device, and the downlink control information can schedule up to N TBs, and the downlink control information includes a first bit.

In an embodiment of the present application, the first bit is 2 bits, and the bit state of the first bit can belong to the first state set or the second state, so that the terminal device can adopt multi-TB scheduling or single-TB scheduling according to the first bit. The bit state of the first bit belongs to the first state set, and the first state set is {01, 10, 11}, N=4, and the downlink control information includes a first field, and the first field includes 5 bits. The bit state of the first bit can determine the number of TBs L scheduled by the downlink control information, and the bit state of the 5 bits of the first field can determine the HARQ process number of the L TBs and the information of the L TBs, so that the downlink control information supports the scheduling of any number of TBs in the N TBs, and can indicate any HARQ process number and any NDI information for each scheduled TB, thereby improving the flexibility of scheduling.

[0100] See also Figure 4 As shown, it is a schematic diagram of an interactive process of an information processing method provided in an embodiment of the present application. The subsequent steps 401 to 406 are described from the network device side, and the subsequent steps 411 to 416 are described from the terminal device side, which mainly includes the following steps:

[0101] 401. The network device determines the number L of transmission blocks TB scheduled by downlink control information, where the downlink control information can schedule a maximum of N TBs, N and L are positive integers, and 1≤L≤N.

[0102] 402. The network device determines the hybrid automatic repeat request HARQ process numbers of L TBs.

[0103] 403. The network device determines L TBs of new data indication NDI information.

[0104] The execution method of step 401 to step 403 is similar to the execution method of step 201 to step 203 of the aforementioned embodiment, and will not be repeated here.

[0105] 404. The network device sends downlink control information to the terminal device, where the downlink control information includes a first bit, and the first bit includes 1 bit.

[0106] like Figure 5a As shown, the bit state of the first bit is the third state, N is greater than 1, and the downlink control information includes a second field, and the second field indicates the number of TBs L scheduled by the downlink control information, the HARQ process numbers of the L TBs, and the NDI information of the L TBs in the first value set; or,

[0107] like Figure 5b As shown, the bit state of the first bit is the fourth state, the downlink control information also includes a second bit, the second bit includes 1 bit, the bit state of the second bit is the fifth state, N is greater than 1, and the downlink control information includes a third field, the third field indicates the number of TBs L scheduled by the downlink control information, the HARQ process numbers of the L TBs, and the NDI information of the L TBs in the second value set, wherein the second value set and the first value set are different sets, and the number of bits included in the third field is one bit less than the number of bits included in the second field; or,

[0108] like Figure 5c As shown, the bit state of the first bit is the fourth state, the downlink control information also includes a second bit, the second bit includes 1 bit, the bit state of the second bit is the sixth state, N=1, the HARQ process index indication field included in the downlink control information is used to indicate the HARQ process number of 1 TB, and the NDI field included in the downlink control information is used to indicate the NDI information of 1 TB.

[0109] For example, the third state may be 1. When the bit state of the first bit is the third state, and N is greater than 1, it indicates that the downlink control information schedules multiple TBs. In this case, in addition to the first bit, the downlink control information may also include a second field. The second field indicates the number of TBs L, the HARQ process numbers of the L TBs, and the NDI information of the L TBs scheduled by the downlink control information in the first value set. Among them, the second field in the first value set may be an index value corresponding to the bit state of the second field belonging to the first value set, or the second field in the first value set may be a value of the second field belonging to the first value set. For example, if the size of the downlink control information is 7 bits and the first bit is 1 bit, the second field is 6 bits. The bit state of the 6 bits of the second field is used to indicate the HARQ process numbers of L and L TBs and the NDI information of L TBs. For example, 6 bits can represent 2 664 bit states, that is, 64 states can be used to indicate the HARQ process number corresponding to each TB and whether each TB is a new transmission TB or a retransmission TB.

[0110] For example, the fourth state may be 0. When the bit state of the first bit is the fourth state, the downlink control information also includes the second bit, the second bit includes 1 bit, and the bit state of the second bit is the fifth state. For example, the fifth state is 1, and N is greater than 1, indicating that the downlink control information schedules multiple TBs. In addition to the first bit and the second bit, the downlink control information also includes a third field. The third field indicates the number of TBs L, the HARQ process numbers of the L TBs, and the NDI information of the L TBs scheduled by the downlink control information in the second value set. Among them, the third field in the second value set may be that the index value corresponding to the bit state of the third field belongs to the second value set, or the third field in the second value set may be that the value of the third field belongs to the second value set. For example, if the size of the downlink control information is 7 bits, the first bit is 1 bit, and the second bit is 1 bit, then the third field is 5 bits, and the bit state of the 5 bits of the third field is used to indicate the HARQ process numbers of L and L TBs and the NDI information of L TBs. For example, 5 bits can represent 2 5 32 bit states, that is, 32 states can be used to indicate the HARQ process number corresponding to each TB and whether each TB is a new transmission TB or a retransmission TB.

[0111] The second value set is different from the first value set, and the number of bits contained in the third field is one bit less than the number of bits contained in the second field, for example, the third field is 5 bits and the second field is 6 bits. For different values ​​of the bit state of the first bit, the downlink control information includes different fields, and the terminal device needs to determine which method to use to parse the downlink control information according to the indication of the first bit.

[0112] For example, the fourth state may be 0, the bit state of the first bit is the fourth state, the downlink control information also includes a second bit, the second bit includes 1 bit, and the bit state of the second bit is the sixth state. For example, the sixth state is 0, and N=1, indicating that the downlink control information schedules a single TB. The downlink control information may include: a HARQ process index indication field and an NDI field. The HARQ process index indication field occupies 1 bit, and the NDI field occupies 1 bit. The HARQ process index indication field is used to indicate the HARQ process number of 1 TB, and the NDI field is used to indicate the NDI information of 1 TB. In the embodiment of the present application, it is not necessary to use 1 bit separately in the downlink control information to indicate single-TB scheduling or multi-TB scheduling, and it is possible to support the scheduling of any number of TBs in N TBs by one downlink control information, and any HARQ process number can be indicated for each scheduled TB, thereby improving the flexibility of scheduling and saving the bit overhead of the downlink control information.

[0113] 411. The terminal device receives downlink control information from the network device, wherein the downlink control information can schedule a maximum of N transmission blocks TB, where N is a positive integer; the downlink control information includes a first bit, and the first bit includes 1 bit.

[0114] Among them, the network device sends downlink control information to the terminal device, and the downlink control information includes a first bit, and the first bit includes 1 bit. According to different values ​​of the bit state of the first bit, the terminal device parses the downlink control information in different ways. For example, if the bit state of the first bit is the third state, the terminal device executes step 412. If the bit state of the first bit is the fourth state and the second bit is the fifth state, the terminal device executes step 413. If the bit state of the first bit is the fourth state and the second bit is the sixth state, the terminal device executes step 414.

[0115] 412. The bit state of the first bit is the third state, N is greater than 1, and the downlink control information includes a second field, and the terminal device determines the number of TBs L, the HARQ process numbers of the L TBs, and the NDI information of the L TBs scheduled by the downlink control information in the first value set according to the second field; or,

[0116] 413. The bit state of the first bit is the fourth state, the downlink control information also includes a second bit, the second bit includes 1 bit, the bit state of the second bit is the fifth state, N is greater than 1, and the downlink control information includes a third field, and the terminal device determines the number of TBs L, the HARQ process numbers of the L TBs, and the NDI information of the L TBs scheduled by the downlink control information in the second value set according to the third field, wherein the second value set and the first value set are different sets, and the number of bits included in the third field is one bit less than the number of bits included in the second field; or

[0117] 414. The bit state of the first bit is the fourth state, the downlink control information also includes a second bit, the second bit includes 1 bit, the bit state of the second bit is the sixth state, N=1, the terminal device determines the HARQ process number of 1 TB according to the HARQ process index indication field included in the downlink control information, and determines the NDI information of 1 TB according to the NDI field included in the downlink control information.

[0118] like Figure 5a As shown, the bit state of the first bit is the third state, N is greater than 1, and the downlink control information includes a second field, and the second field indicates the number of TBs L scheduled by the downlink control information, the HARQ process numbers of the L TBs, and the NDI information of the L TBs in the first value set; or,

[0119] like Figure 5b As shown, the bit state of the first bit is the fourth state, the downlink control information also includes a second bit, the second bit includes 1 bit, the bit state of the second bit is the fifth state, N is greater than 1, and the downlink control information includes a third field, the third field indicates the number of TBs L scheduled by the downlink control information, the HARQ process numbers of the L TBs, and the NDI information of the L TBs in the second value set, wherein the second value set and the first value set are different sets, and the number of bits included in the third field is one bit less than the number of bits included in the second field; or,

[0120] like Figure 5c As shown, the bit state of the first bit is the fourth state, the downlink control information also includes a second bit, the second bit includes 1 bit, the bit state of the second bit is the sixth state, N=1, the HARQ process index indication field included in the downlink control information is used to indicate the HARQ process number of 1 TB, and the NDI field included in the downlink control information is used to indicate the NDI information of 1 TB.

[0121] For example, the third state may be 1. When the bit state of the first bit is the third state, and N is greater than 1, it indicates that the downlink control information schedules multiple TBs. In this case, in addition to the first bit, the downlink control information may also include a second field. The second field indicates the number of TBs L, the HARQ process numbers of the L TBs, and the NDI information of the L TBs scheduled by the downlink control information in the first value set. Among them, the second field in the first value set may be an index value corresponding to the bit state of the second field belonging to the first value set, or the second field in the first value set may be a value of the second field belonging to the first value set. For example, if the size of the downlink control information is 7 bits and the first bit is 1 bit, the second field is 6 bits. The bit state of the 6 bits of the second field is used to indicate the HARQ process numbers of L and L TBs and the NDI information of L TBs. For example, 6 bits can represent 2 6 64 bit states, that is, 64 states can be used to indicate the HARQ process number corresponding to each TB and whether each TB is a new transmission TB or a retransmission TB.

[0122] For example, the fourth state may be 0. When the bit state of the first bit is the fourth state, the downlink control information also includes the second bit, the second bit includes 1 bit, and the bit state of the second bit is the fifth state. For example, the fifth state is 1, and N is greater than 1, indicating that the downlink control information schedules multiple TBs. In addition to the first bit and the second bit, the downlink control information also includes a third field. The third field indicates the number of TBs L, the HARQ process numbers of the L TBs, and the NDI information of the L TBs scheduled by the downlink control information in the second value set. Among them, the third field in the second value set may be that the index value corresponding to the bit state of the third field belongs to the second value set, or the third field in the second value set may be that the value of the third field belongs to the second value set. For example, if the size of the downlink control information is 7 bits, the first bit is 1 bit, and the second bit is 1 bit, then the third field is 5 bits, and the bit state of the 5 bits of the third field is used to indicate the HARQ process numbers of L and L TBs and the NDI information of L TBs. For example, 5 bits can represent 2 5 32 bit states, that is, 32 states can be used to indicate the HARQ process number corresponding to each TB and whether each TB is a new transmission TB or a retransmission TB.

[0123] The second value set is different from the first value set, and the number of bits contained in the third field is one bit less than the number of bits contained in the second field, for example, the third field is 5 bits and the second field is 6 bits. For different values ​​of the bit state of the first bit, the downlink control information includes different fields, and the terminal device needs to determine which method to use to parse the downlink control information according to the indication of the first bit.

[0124] For example, the fourth state may be 0, the bit state of the first bit is the fourth state, the downlink control information also includes a second bit, the second bit includes 1 bit, and the bit state of the second bit is the sixth state. For example, the sixth state is 0, and N=1, indicating that the downlink control information schedules a single TB. The downlink control information may include: a HARQ process index indication field and an NDI field. The HARQ process index indication field occupies 1 bit, and the NDI field occupies 1 bit. The HARQ process index indication field is used to indicate the HARQ process number of 1 TB, and the NDI field is used to indicate the NDI information of 1 TB. In the embodiment of the present application, it is not necessary to use 1 bit separately in the downlink control information to indicate single-TB scheduling or multi-TB scheduling, and it is possible to support the scheduling of any number of TBs in N TBs by one downlink control information, and any HARQ process number can be indicated for each scheduled TB, thereby improving the flexibility of scheduling and saving the bit overhead of the downlink control information.

[0141] Among them, the network device can determine that the DCI can schedule a maximum of N TBs. N can be a fixed value specified by the standard, or the network device configures N to the terminal device. For example, the network device configures N to the terminal device through radio resource control signaling, or the network device configures N to the terminal device through media access control signaling, or the network device configures N to the terminal device through physical layer signaling. For example, the value set of N is {1, 2, 4, 8}. Or, the value set of N is {2, 4, 8}. Or, the value set of N is {1, 4, 8}. Or, the value set of N is {1, 2, 8}, or, the value set of N is {2, 8}.

[0143] See also Figure 6 As shown, it is a schematic diagram of an interactive process of an information processing method provided in an embodiment of the present application. The subsequent steps 601 to 606 are described from the network device side, and the subsequent steps 611 to 616 are described from the terminal device side, which mainly includes the following steps:

[0144] 601. The network device determines the number L of transmission blocks TB scheduled by downlink control information, where the downlink control information can schedule a maximum of N TBs, N and L are positive integers, and 1≤L≤N;

[0145] 602. The network device determines the hybrid automatic repeat request HARQ process numbers of L TBs;

[0148] 604. The network device sends downlink control information to the terminal device. The downlink control information includes a first bit and a second bit. The first bit includes 7 bits, and the second bit includes 3 bits.

[0149] The first bit is used to indicate the number of transport blocks TB scheduled by downlink control information, and is also used to indicate the index of the modulation and coding scheme (MCS);

[0150] L=1, one bit in the second bit is a new data indication NDI bit, and the bit states of the two bits in the second bit except the one NDI bit are used to indicate the hybrid automatic repeat request HARQ process number of one TB; or,

[0155] Specifically, the first bit is 7 bits, and 3 bits of the first bit and 4 bits of the MCS index indicated by the downlink control information are jointly encoded to indicate the number of TBs scheduled by the downlink control information and the MCS index. Therefore, the number of TBs L and the MCS index can be determined according to the first bit, and the MCS index requires a total of 10 or 11 bit states to indicate. The downlink control information can schedule a maximum of N TBs, N = 4, then the number of TBs L scheduled by the downlink control information can be 1, or 2, or 3, or 4, and the different bit states in the first bit can be used to specifically determine that L can be 1, or 2, or 3, or 4.

[0156] In some embodiments of the present application, the network device can determine that L=1, the second bit has a total of 3 bits, 1 bit of the second bit is the new data indication NDI bit, so the NDI information of 1 TB can be determined through the NDI bit, and the bit state of 2 bits in the second bit except 1 NDI bit is used to indicate the hybrid automatic repeat request HARQ process number of 1 TB, so the HARQ process number of 1 TB can be indicated as any HARQ process number, thereby realizing flexible scheduling of downlink control information.

[0157] In some embodiments of the present application, the network device can determine that L=2, the second bit has a total of 3 bits, 2 of the second bits are NDI bits, and therefore the NDI information of 2 TBs can be determined by 2 NDI bits. The bit state of 1 bit in the second bit other than the 2 NDI bits and the bit state of the first bit are used to indicate the HARQ process number of the 2 TBs, and therefore the HARQ process number of the 3 TBs can be indicated as any HARQ process number, thereby realizing flexible scheduling of downlink control information.

The bit state of the first bit is used to indicate the HARQ process number of the 3 TBs, and therefore the HARQ process number of the 3 TBs can be indicated as any HARQ process number, thereby realizing flexible scheduling of downlink control information.

[0159] In some embodiments of the present application, the network device can determine that L=4, the downlink control information schedules 4 TBs, and the 4 TBs can use 4 HARQ process numbers, that is, all HARQ process numbers need to be used, and the downlink control information does not need to indicate the HARQ process numbers of the 4 TBs. The second bit has a total of 3 bits, and 3 bits in the second bit are NDI bits corresponding to 3 TBs out of the 4 TBs. Therefore, the NDI information of the 3 TBs can be determined by the 3 NDI bits. The bit state of the first bit is used to indicate the NDI bit corresponding to 1 TB out of the 4 TBs except the 3 TBs corresponding to the NDI bit. The bit state of the first bit can also indicate the NDI information of the 4th TB out of the 4 TBs. Therefore, the NDI information of the 4 TBs can be indicated, and flexible scheduling of downlink control information can be achieved.

[0160] 611. The terminal device receives downlink control information from the network device, wherein the downlink control information can schedule a maximum of 4 transport blocks TB; the downlink control information includes a first bit and a second bit, the first bit includes 7 bits, the second bit includes 3 bits,

[0169] Specifically, the first bit is 7 bits, and 3 bits of the first bit and 4 bits of the MCS index indicated by the downlink control information are jointly encoded to indicate the number of TBs scheduled by the downlink control information and the MCS index. Therefore, the number of TBs L and the MCS index can be determined according to the first bit, and the MCS index requires a total of 10 or 11 bit states to indicate. The downlink control information can schedule a maximum of N TBs, N = 4, then the number of TBs L scheduled by the downlink control information can be 1, or 2, or 3, or 4, and the different bit states in the first bit can be used to specifically determine that L can be 1, or 2, or 3, or 4.

[0173] In some embodiments of the present application, the network device can determine that L=4, the downlink control information schedules 4 TBs, and the 4 TBs can use 4 HARQ process numbers, that is, all HARQ process numbers need to be used, and the downlink control information does not need to indicate the HARQ process numbers of the 4 TBs. The second bit has a total of 3 bits, and 3 bits in the second bit are NDI bits corresponding to 3 TBs out of the 4 TBs. Therefore, the NDI information of the 3 TBs can be determined by the 3 NDI bits. The bit state of the first bit is used to indicate the NDI bit corresponding to 1 TB out of the 4 TBs except the 3 TBs corresponding to the NDI bit. The bit state of the first bit can also indicate the NDI information of the 4th TB out of the 4 TBs.

[0196] In order to better understand and implement the above-mentioned solutions in the embodiments of the present application, the following examples are given for specific explanation by using corresponding application scenarios.

[0197] In an embodiment of the present application, a first node sends first information to a second node. The first node may be a base station, or a device with a sending capability. The second node may be a user equipment, or a device with a receiving capability, or a base station. For example, the first node sends the first information to the second node via downlink control information. That is, the downlink control information includes the first information. Alternatively, the first node sends the first information to the second node via radio resource control signaling or media access control signaling. That is, the radio resource control signaling or media access control signaling includes the first information.

[0198] It should be noted that in the embodiments of the present application, transmission is sending or receiving. If one end of the communication implements the transmission as sending, the other end of the communication implements it as receiving.

[0199] Step S01: A first node determines first information.

[0200] Step S02: The first node sends first information to the second node.

[0201] The first node may be a base station, or a device with a sending capability. The second node may be a user equipment, or a device with a receiving capability, or a base station. For example, the first node sends the first information to the second node via downlink control information (DCI). That is, the downlink control information includes the first information. Alternatively, the first node sends the first information to the second node via radio resource control signaling or media access control signaling. That is, the radio resource control signaling or media access control signaling includes the first information.

[0202] It should be noted that in the embodiments of the present application, transmission is sending or receiving. If one end of the communication implements the transmission as sending, the other end of the communication implements it as receiving.

[0203] One DCI can schedule a maximum of N TBs. The value of the HARQ process number of each TB is 0, 1, 2...N-1.

[0204] N can be a fixed value specified by the standard, or the first node configures N to the second node. For example, the first node configures N to the second node through radio resource control signaling, or the first node configures N to the second node through media access control signaling, or the first node configures N to the second node through physical layer signaling. For example, the value set of N is {1, 2, 4, 8}. Or, the value set of N is {2, 4}. Or, the value set of N is {1, 4}. Or, the value set of N is {1, 4, 8}.

[0205] When N is greater than 1, the DCI supports that the multiple TBs scheduled may include new transmission TBs and retransmission TBs, and the HARQ process number corresponding to each TB in the multiple TBs scheduled may also be arbitrary.

[0206] As shown in Table 1 below, 7 bits are used to indicate the number of scheduled TBs L, the HARQ process number of each TB, and the NDI of each TB.

[0207] First Bit TB number L, HARQ process number and NDI 00 L = 1, 1 bit indicates the HARQ process number, 1 bit indicates NDI 01 L = 2, 5 bits are used to indicate the HARQ process number and 2 TB NDI 10 L = 3, 5 bits are used to indicate the HARQ process number and the NDI of 3 TBs 11 L = 4, 5 bits are used to indicate the HARQ process number and the NDI of 4 TBs

[0208] As shown in Table 1, the downlink control information includes a first bit, and the first bit includes 2 bits. When the bit state of the first bit is the first state set {01, 10, 11}, N=4, and the first bit is used to indicate the number of TBs L scheduled by the DCI. Further, the downlink control information includes a first field, and the first field includes 5 bits, which are used to indicate the number of TBs L scheduled by the DCI, the HARQ process number corresponding to each scheduled TB, and the NDI information of each TB. When the bit state of the first bit is the second state {00}, N=1, the downlink control information includes a HARQ process index indication field and an NDI indication field, which are respectively used to indicate the HARQ process number and NDI information corresponding to 1 TB scheduled by the DCI;

[0209] As shown in Table 2 below, K bits indicate the number of TBs scheduled by DCI, the HARQ process number corresponding to each TB, and the new transmission and retransmission indication of each TB.

[0210]

[0211] As shown in Table 2, the first bit includes 1 bit, when the bit state of the first bit is 1, N is greater than 1, and the downlink control information includes a second field, and the second field indicates the number of TBs L scheduled by DCI, the HARQ process number of each TB, and the NDI information of each TB in the first value set. When the bit state of the first bit is 0, the downlink control information includes a second bit, and the second bit includes one bit. When the bit state of the second bit is 1, N is greater than 1, and the downlink control information includes a third field, and the third field indicates the number of TBs L scheduled by DCI, the HARQ process number corresponding to each TB, and the NDI information of each TB in the second value set, wherein the second value set and the first value set are different sets, and the third field is 1 bit less than the second field; when the bit state of the second bit is 0, N=1, and the downlink control information includes a HARQ process index indication field and an NDI indication field, which are respectively used to indicate the HARQ process number and NDI information corresponding to 1 TB scheduled by DCI.

[0212] The following describes an implementation scenario of the embodiment of the present application from the first node side:

[0213] The first node indicates the number of TBs scheduled.

[0214] The first node determines the number of TBs scheduled by a DCI, and indicates the first bit according to the number of scheduled TBs L. If L=1, the first bit is 00; if L=2, the first bit is 01; if L=3, the first bit is 10; if L=4, the first bit is 11.

[0215] The first node indicates the HARQ process number corresponding to each TB and the NDI information of each TB.

[0216] The first node determines the HARQ process number corresponding to each scheduled TB and the NDI information of each TB. If the first bit state is the first state set, the first node indicates the HARQ process number corresponding to each scheduled TB and the NDI information of each TB with 5 bits in the first field. If the first bit state is the second state, the first node indicates the HARQ process number of 1 TB with 1 bit, and indicates the NDI information of 1 TB with 1 bit.

[0217] The first node sends a DCI to the second node.

[0218] The specific implementation method of the embodiment of the present application is illustrated below with L=4. A total of 7 bits are required for multi-TB scheduling indication, including the number of scheduled TBs, the HARQ process number of each TB, and the NDI information of each TB.

[0219] The base station determines to schedule 4 TBs, that is, L=4. Therefore, the base station sets the first bit state to 11.

[0220] The base station determines that the HARQ process numbers corresponding to each scheduled TB are 0, 1, 2, and 3 respectively, and the NDI information of each TB is 0, 0, 0, 0 respectively. The base station sets the bit state of the first field to 00000 according to the correspondence between the bit state of the first field in Table 3 and the HARQ process number and NDI information.

[0221] As shown in Table 3 below, DCI schedules 4 TBs, and the first field bit status indicates the HARQ process number and NDI.

[0222] Bit status of the first field HARQ process number and NDI 00000 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=0,N1=0,N2=0,N3=0]]> 00001 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=0,N1=0,N2=0,N3=1]]> 00010 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=0,N1=0,N2=1,N3=0]]> 00011 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=0,N1=0,N2=1,N3=1]]> 00100 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=0,N1=1,N2=0,N3=0]]> 00101 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=0,N1=1,N2=0,N3=1]]> 00110 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=0,N1=1,N2=1,N3=0]]> 00111 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=0,N1=1,N2=1,N3=1]]> 01000 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=1,N1=0,N2=0,N3=0]]> 01001 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=1,N1=0,N2=0,N3=1]]> 01010 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=1,N1=0,N2=1,N3=0]]> 01011 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=1,N1=0,N2=1,N3=1]]> 01100 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=1,N1=1,N2=0,N3=0]]> 01101 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=1,N1=1,N2=0,N3=1]]> 01110 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=1,N1=1,N2=1,N3=0]]> 01111 <![CDATA[H0=0,H1=1,H2=2,H3=3,N0=1,N1=1,N2=1,N3=1]]>

[0223] Therefore, the bit state of the DCI indicating the scheduled 4 TBs is 1100000. The base station sends the indication to the user equipment through signaling.

[0224] The following describes an implementation scenario of the embodiment of the present application from the second node side:

[0225] The second node receives the DCI.

[0226] The second node determines the number L of TBs scheduled by the DCI.

[0227] The second node determines the bit state of the first bit, and determines the number of TBs scheduled by the DCI accordingly. If the first bit is 00, L=1; if the first bit is 01, L=2; if the first bit is 10, L=3; if the first bit is 11, L=4.

[0228] The second node determines the HARQ process number corresponding to each scheduled TB and the NDI information of each TB.

[0229] If the second node determines that the bit state of the first bit belongs to the first state set, the second node determines the HARQ process number corresponding to each TB in the L scheduled TBs and the NDI information of each TB according to the bit state of the first field; if the second node determines that the bit state of the first bit belongs to the second state, the second node determines the HARQ process number corresponding to 1 scheduled TB according to the HARQ index indication field, and determines the NDI information of the TB according to the NDI field.

[0230] The implementation of the embodiment of the present application is explained below by taking the second node receiving a specific bit state. For example, the bit state received by the second node is 1100000.

[0231] The first bit state is 11, and the second node determines that the DCI schedules 4 TBs according to the first bit state.

[0232] The second node determines that the first bit state belongs to the first state set, and further determines that the HARQ process numbers used for the scheduled 4 TBs are 0, 1, 2, 3 respectively according to the correspondence between the bit state of the first field and the HARQ process number and NDI information in Table 3, and the NDI corresponding to each TB is 0, 0, 0, 0.

[0233] The following describes an implementation scenario of the embodiment of the present application from the first node side:

[0234] The first node indicates the number of scheduled TBs, the HARQ process number corresponding to each TB, and the NDI information of each TB.

[0235] The first node determines the number of TBs scheduled by a DCI, the HARQ process number corresponding to each TB, and the NDI information of each TB.

[0236] The first node indicates that the bit state of the first bit is 1, and the second field indicates the number L of TBs scheduled by DCI, the HARQ process number corresponding to each TB, and the NDI information of each TB in the first value set; the first node indicates that the bit state of the first bit is 0, the bit state of the second bit is 1, and the third field indicates the number L of TBs scheduled by DCI, the HARQ process number corresponding to each TB, and the NDI information of each TB in the second value set; the first node indicates that the bit state of the first bit is 0, the bit state of the second bit is 0, and the second node uses the HARQ process index indication field to indicate the HARQ process number used for 1 TB, and uses the NDI field to indicate the NDI information of 1 TB.

[0237] The first node sends a DCI to the second node.

[0238] The following example uses N=4 and L=4 as an example to illustrate an implementation scenario of the present application. A total of K=7 bits are required for multi-TB scheduling indication, including the number of scheduled TBs, the HARQ process number of each TB, and the NDI of each TB. Assume that the number of TBs included in the first value set is {2, 3}; the number of TBs included in the second value set is {4}.

[0239] The base station indicates that DCI schedules 4 TBs, the HARQ process numbers corresponding to each TB are 0, 1, 2, and 3, and the NDI indications of each TB are 0, 0, 0, and 0, respectively. Therefore, the base station sets the first bit state to 0 and the second bit to 1, and indicates that the bit state of the third field is 00000 according to the correspondence between the third field and L, HARQ process number, and NDI information in Table 4.

[0240] As shown in Table 4 below, DCI schedules 4 TBs, and the third field bit status indicates L, HARQ process number and NDI.

[0241]

[0242]

[0243] Therefore, the bit state of the DCI indicating scheduling of 4 TBs is 0100000. The base station sends the indication to the user equipment through signaling.

[0244] The following describes an implementation scenario of the embodiment of the present application from the second node side:

[0245] The second node determines that the DCI can schedule a maximum of N TBs.

[0246] N can be a fixed value specified by the standard, or the first node configures N to the second node. For example, the first node configures N to the second node through radio resource control signaling, or the first node configures N to the second node through media access control signaling, or the first node configures N to the second node through physical layer signaling. For example, the value set of N is {1, 2, 4, 8}. Or, the value set of N is {2, 4}. Or, the value set of N is {1, 4}. Or, the value set of N is {1, 4, 8}.

[0247] The second node receives the DCI, and determines the number of TBs scheduled by the DCI, the HARQ process number corresponding to each TB, and the NDI information of each TB.

[0248] The second node determines that the bit state of the first bit is 1, then the second node determines the number of TBs scheduled by DCI, the HARQ process number corresponding to each TB and the NDI information of each TB in the first value set according to the second field; the second node determines that the bit state of the first bit is 0 and the bit state of the second bit is 1, then the second node determines the number of TBs scheduled by DCI, the HARQ process number corresponding to each TB and the NDI information of each TB in the first value set according to the third field; the second node determines that the bit state of the first bit is 0 and the bit state of the second bit is 0, then the second node determines the HARQ process number used for 1 TB according to the HARQ process index indication field, and determines the NDI information of 1 TB according to the NDI field.

[0249] The following describes an implementation method of the present application embodiment using a specific bit state received by the second node. Assume that N=4, the number of TBs included in the first value set is {2, 3}; the number of TBs included in the second value set is {4}, and the bit state of the 7 bits received by the second node is 0100000.

[0250] The second node determines that the bit state of the first bit is 0, and the bit state of the second bit is 1. The second node determines that the DCI schedules 4 TBs according to the correspondence between the third field and L, the HARQ process number, and the NDI information in Table 4, and the HARQ process number corresponding to each TB is 0, 1, 2, and 3, respectively, and the NDI indication of each TB is 0, 0, 0, and 0, respectively.

[0251] From the above examples, we can see that only bits can support scheduling of any number of TBs in N TBs by one DCI, and can indicate any HARQ process number for each scheduled TB, thereby improving scheduling flexibility and saving DCI bit overhead.

[0252] When scheduling a maximum of N TBs, the embodiment of the present application requires bits are used to indicate multi-TB scheduling, so the embodiments of the present application can flexibly indicate the HARQ process number of each TB during multi-TB scheduling with less bit overhead, and can distinguish between multi-TB scheduling and single TB scheduling.

[0253] Next, another embodiment of the present application is described.

[0254] The first node determines first information.

[0255] The first node sends first information to the second node.

[0256] The first node may be a base station, or a device with a sending capability. The second node may be a user equipment, or a device with a receiving capability, or a base station. For example, the first node sends the first information to the second node via downlink control information (DCI). That is, the downlink control information includes the first information. Alternatively, the first node sends the first information to the second node via radio resource control signaling or media access control signaling. That is, the radio resource control signaling or media access control signaling includes the first information. The first information includes 6+S bits, that is, 6+S bits in the DCI indicate the first information.

[0257] It should be noted that in the embodiments of the present application, transmission is sending or receiving. If one end of the communication implements the transmission as sending, the other end of the communication implements it as receiving.

[0258] One DCI can schedule up to 4 TBs. The value of the HARQ process number of each TB is {0-3}.

[0259] The maximum number of 4 TBs to be scheduled may be a fixed value specified by the standard, or the first node may configure N to the second node. For example, the first node may configure N to the second node through radio resource control signaling, or the first node may configure N to the second node through media access control signaling, or the first node may configure N to the second node through physical layer signaling.

[0260] The multiple TBs scheduled by DCI may include new transmission TBs and retransmission TBs, and the HARQ process number corresponding to each TB in the multiple TBs scheduled may also be arbitrary.

[0261] The first information includes a first bit (also referred to as a first field). When the bit state of the first bit is a first state (such as 1), the first node indicates that the DCI schedules multiple TBs, and the number of scheduled TBs is a first set {2, 4}. The remaining 5 bits in the first information except the S bits can represent 2 5 = 32 bit states, used to indicate the number of TBs scheduled from the first set, the HARQ process number corresponding to each TB, and whether each TB is newly transmitted or retransmitted, and the 32 states are used to indicate some combinations of scheduling 2 TBs and 4 TBs. For example, 24 combinations of scheduling 4 TBs and 8 combinations of scheduling 2 TBs are indicated, or 16 combinations of scheduling 2 TBs and 16 combinations of scheduling 4 TBs are indicated.

[0262] When the bit state of the first bit is the second state (such as 0), the first node indicates that the DCI schedules one or more TBs, and the number of scheduled TBs is a second set, and the second set includes one or more TB numbers.

[0263] Further, when the state of the first bit is the second state (such as 0), the method in which the DCI schedules the TB is determined according to the bit state of the second bit. When the bit state of the second bit is the first state (such as 1), the first node indicates that the DCI can schedule multiple TBs, and the number of scheduled TBs is the third set {3}, and the remaining 4 bits in the first information except the S bits are combined with the field indicated by the S bits through compression or joint coding to save one bit to represent 2 5 = 32 bit states. For example, the MCS field and the repetition number RN field may be jointly encoded and indicated by S-1 bits in the DCI. The 32 bit states are used to indicate all combinations of scheduling 3 TBs.

[0264] Further, when the bit state of the second bit is the second state (such as 0), the DCI is determined according to the bit state of the third bit in which way to schedule the TB. When the bit state of the third bit is the first state (such as 1), the first node indicates that the DCI can schedule multiple TBs, and the number of scheduled TBs is the fourth set, and the fourth set and the first set have one element different. The remaining 3 bits in the first information except the S bits can represent 8 states, which are used to indicate the number of TBs scheduled from the fourth set, the HARQ process number corresponding to each TB, and whether each TB is newly transmitted or retransmitted. The 8 states and the 32 states indicating the first set indicate all combinations of scheduling 4 TBs and 2 TBs. When the bit state of the third bit is the second state (such as 0), the first node indicates that the DCI schedules a single TB, and the remaining 3 bits in the first information except the S bits indicate the HARQ process number corresponding to the scheduled TB and whether the TB is newly transmitted or retransmitted according to the existing single TB scheduling method.

[0265] As shown in Table 5, 6 bits are introduced into the DCI to indicate that a maximum of 4 TBs are scheduled.

[0266] Table 5, 13 bits indicate scheduling of up to 4 TBs.

[0267]

[0268] The first set, the second set, the third set and the fourth set may be fixed values ​​specified by the standard, or the first node may be configured to the second node. For example, the first node may be configured to the second node via radio resource control signaling, or the first node may be configured to the second node via media access control signaling, or the first node may be configured to the second node via physical layer signaling.

[0269] The following describes an embodiment of the present application from the first node side:

[0270] The first node indicates the number of scheduled HARQ processes, the HARQ process number corresponding to each scheduled TB, whether each scheduled TB is a new transmission or a retransmission, the MCS and the RN.

[0271] The first node determines the number of TBs scheduled by a DCI, the HARQ process number used for each scheduled TB, and whether each scheduled TB is newly transmitted or retransmitted, and determines the TB number set to which the scheduled TB number belongs accordingly. If the scheduled TB number belongs to the first set, the first node sets the bit state of the first bit to 1, uses 7 bits to indicate MCS and RN in an existing manner, and uses 5 bits other than the 7 bits and the first bit to indicate the number of TBs scheduled by the DCI, the HARQ process number used for each scheduled TB, and whether each scheduled TB is newly transmitted or retransmitted; if the scheduled TB number belongs to the second set, the first node sets the bit state of the first bit to 0.

[0272] If the first node sets the first bit to 0, further determine the TB number set to which the number of TBs scheduled by the DCI belongs. If the number of TBs scheduled belongs to the third set, the first node sets the bit state of the second bit to 1, jointly encodes the MCS field and the RN field, uses 6 bits to indicate the information, and uses 5 bits other than the 6 bits, the first bit, and the second bit to indicate the HARQ process number used for each TB scheduled by the DCI and whether each scheduled TB is newly transmitted or retransmitted.

[0273] If the number of TBs scheduled by DCI belongs to the fourth set, the first node sets the bit state of the second bit to 0 and the bit state of the third bit to 1, uses 7 bits to indicate MCS and RN in the existing manner, and uses 3 bits other than the 7 bits, the first bit, the second bit, and the third bit to indicate the HARQ process number used for each TB scheduled by DCI and whether each scheduled TB is a new transmission or a retransmission.

[0274] If DCI schedules a single TB, the second node sets the bit state of two bits to 0, and sets the bit state of the third node to 0, and uses 7 bits to indicate MCS and RN in the existing manner, and uses 3 bits other than the 7 bits, the first bit, the second bit, and the third bit to indicate the HARQ processnumber corresponding to the DCI-scheduled TB and whether the TB is newly transmitted or retransmitted in accordance with the existing technology.

[0275] The first node sends a DCI to the second node.

[0276] The following describes an embodiment of the present application from the second node side:

[0277] The second node receives DCI, which includes 13 bits, indicating the number of scheduled HARQ processes, the HARQ process number corresponding to each TB, whether each TB is newly transmitted or retransmitted, and MCS and RN indications.

[0278] The second node determines the bit state of the first bit of the 13 bits. If the bit state of the first bit is 1, the second node determines that the number of scheduled TBs belongs to the first set. Further, the MCS and RN are determined according to the 7 bits, and the number of DCI scheduled TBs, the HARQ process number corresponding to each scheduled TB, and whether each TB is newly transmitted or retransmitted are determined according to the 5 bits other than the 7 bits and the first bit.

[0279] If the bit state of the first bit is 0, the second node determines the bit state of the second bit. If the bit state of the second bit is 1, the second node determines that the number of scheduled TBs belongs to the third set. Further, the MCS and RN are determined according to the 6 bits, and the HARQ process number corresponding to each TB scheduled by the DCI and whether each TB is newly transmitted or retransmitted are determined according to the 5 bits other than the 6 bits, the first bit and the second bit.

[0280] If the bit state of the second bit is 0, the second node determines the bit state of the third bit. If the bit state of the third bit is 1, the second node determines that the number of scheduled TBs belongs to the fourth set. Further, the second node determines the MCS and RN according to the 7 bits, and determines the HARQ process number corresponding to each TB scheduled by the DCI and whether each TB is newly transmitted or retransmitted according to 3 bits other than the 7 bits, the first bit, the second bit and the three bits.

[0281] If the bit state of the third bit is 0, the second node determines that the DCI schedules 1 TB. Further, the second node determines the MCS and RN according to the 7 bits, and determines the HARQ process number corresponding to the TB scheduled by the DCI and whether the TB is newly transmitted or retransmitted according to 3 bits other than the 7 bits, the first bit, the second bit and the third bit.

[0282] 6+S bits are used to indicate multi-TB scheduling and other fields in the DCI respectively. Any HARQ process number can be used to indicate multiple TBs for scheduling, and multi-TB scheduling and single-TB scheduling can be distinguished. However, in essence, only 6 bits are added compared to the existing DCI bit number, which reduces the bit overhead while ensuring the flexibility of scheduling.

[0283] When DCI schedules up to 4 TBs, the embodiment of the present application actually introduces 6 bits for multi-TB scheduling indication, while the prior art requires 8 bits for multi-TB scheduling indication. Therefore, while reducing the bit overhead, the embodiment of the present application can flexibly indicate the HARQ process number of each TB and can also distinguish between multi-TB scheduling and single TB scheduling.

[0284] Next, another embodiment of the present application is described.

[0285] The first node determines first information.

[0286] The first node sends first information to the second node.

[0287] The first node may be a base station, or a device with a sending capability. The second node may be a user equipment, or a device with a receiving capability, or a base station. For example, the first node sends the first information to the second node via downlink control information (DCI). That is, the downlink control information includes the first information. Alternatively, the first node sends the first information to the second node via radio resource control signaling or media access control signaling. That is, the radio resource control signaling or media access control signaling includes the first information. The first information includes 6+S bits, that is, 6+S bits in the DCI indicate the first information.

[0288] It should be noted that in the embodiments of the present application, transmission is sending or receiving. If one end of the communication implements the transmission as sending, the other end of the communication implements it as receiving.

[0289] One DCI can schedule up to 4 TBs. The value of the HARQ process number of each TB is {0-3}.

[0290] The maximum number of 4 TBs to be scheduled may be a fixed value specified by the standard, or the first node may configure N to the second node. For example, the first node may configure N to the second node through radio resource control signaling, or the first node may configure N to the second node through media access control signaling, or the first node may configure N to the second node through physical layer signaling.

[0291] The multiple TBs scheduled by DCI may include new transmission TBs and retransmission TBs, and the HARQ process number corresponding to each TB in the multiple TBs scheduled may also be arbitrary.

[0292] As shown in Table 5, 10 bits are used to indicate the scheduling of {1 to 4} TBs and the indication of the MCS index. The downlink control information includes a first bit and a second bit, the first bit includes 7 bits, and the second bit includes 3 bits. The bit state of the first bit is used to indicate the number of TBs L scheduled by the DCI and other information. If L=1, 1 bit in the second bit is used to indicate the NDI information of 1 TB, and the remaining 2 bits in the second bit are used to indicate the HARQ process number corresponding to 1 TB; if L=2, 2 bits in the second bit are used to indicate the NDI information of 2 TBs, and the sum of the remaining one bit in the second bit and the first bit are used to indicate the HARQ process number corresponding to 2 TBs; if L=3, 3 bits in the second bit are used to indicate the NDI information of 3 TBs, and the first bit is used to indicate the HARQ process number corresponding to 3 TBs; if L=4, 3 bits in the second bit are used to indicate the NDI information of 3 TBs out of the 4 scheduled TBs, and the first bit is used to indicate the NDI information corresponding to the remaining 1 TB.

[0293] As shown in Table 6, 10 bits indicate the number of TBs scheduled by DCI, the HARQ process number corresponding to each TB, the NDI and MCS of each TB.

[0294]

[0295] Table 7 shows the bit state of the first bit and the HARQ process number or NDI corresponding to the scheduled TB.

[0296]

[0297]

[0298] The implementation of the embodiment of the present application is described below from the first node side.

[0299] The first node indicates the number of TBs scheduled by the DCI, the HARQ process corresponding to each scheduled TB, the NDI information and MCS information of each scheduled TB.

[0300] The first node determines the number of TBs scheduled by a DCI, the HARQ process corresponding to each TB scheduled by the DCI, whether each scheduled TB is newly transmitted or retransmitted, and MCS information.

[0301] If the first node determines that DCI schedules 1 TB, the first node uses 1 bit in the second bit to indicate whether the scheduled TB is a new transmission or a retransmission, the first node uses the remaining 2 bits in the second bit to indicate the HARQ process number corresponding to the scheduled TB, and the first node uses the first bit to indicate the MCS information according to the corresponding relationship in Table 7.

[0302] If the first node determines that DCI schedules 2 TBs, the first node uses 2 bits in the second bit to indicate the NDI information of the scheduled TB, the first node uses the first bit to indicate the MCS information, and according to the correspondence in Table 7, uses bit b2 in the second bit and the first bit to indicate the HARQ process number corresponding to each scheduled TB.

[0303] If the first node determines that DCI schedules 3 TBs, the first node uses 3 bits in the second bit to indicate the NDI information of the scheduled TB, the first node uses the first bit to indicate the MCS information, and uses the first bit to indicate the HARQ process number corresponding to each scheduled TB according to the corresponding relationship in Table 7.

[0304] If the first node determines that DCI schedules 4 TBs, the first node uses 3 bits of the second bit to indicate the NDI information of 3 TBs among the 4 scheduled TBs, the first node uses the first bit to indicate the MCS information, and uses the first bit to indicate the HARQNDI information corresponding to the remaining 1 TB scheduled according to the corresponding relationship in Table 7.

[0305] The first node sends a DCI to the second node.

[0379] Another implementation of the embodiment of the present application is described below from the first node side:

[0380] The first node sends downlink control information to the second node. The first node indicates the number of TBs scheduled by the downlink control information, the HARQ process number corresponding to each TB, the NDI of each TB, and the MCS index. There are 11 MCS indexes in total. The downlink control information includes a first bit and a second bit. The first bit includes 6 bits, and the second bit includes 4 bits. The value indicated by the first bit is used to indicate the MCS index and to indicate the number of TBs scheduled.

[0381] The value V indicated by the first bit is used to indicate the MCS index Imcs. Wherein, V=Imcs*5. The value V indicated by the first bit is also used to determine the number of scheduled TBs.

[0382] For example, if DCI schedules 1 TB or DCI schedules 2 TB, and the NDI of the first TB is 0, the value V indicated by the first bit is a multiple of 5. Two bits of the second bit are used to indicate the first HARQ process number (H0). Two bits of the second bit are also used to indicate the second HARQ process number (H1). For example, H0 is indicated in {0,1,2,3}. For example, H1 is indicated in {0,1,2,3}. DCI indicates that 1 TB is scheduled, then H0=H1. And the HARQ process number of this TB is H0. DCI schedules 2 TBs, then H0≠H1, and the HARQ process numbers of the 2 TBs are H0 and H1 respectively. The NDI of the second TB is 0, then H0 H1. Or, the NDI of the second TB=0, then H0>H1. The NDI of the second TB=1, then H0 <H1。 <h1>

[0383] For example, if DCI schedules 1 TB or DCI schedules 2 TB, and the NDI of the first TB is 1, the value indicated by the first bit is V=5m+1, where m is 0 or a positive integer. Two bits of the second bit are used to indicate the first HARQ process number (H0), and two bits of the second bit are used to indicate the second HARQ process number (H1). For example, H0 is indicated in {0,1,2,3}. For example, H1 is indicated in {0,1,2,3}. DCI indicates that 1 TB is scheduled, then H0=H1. And the HARQ process number of this TB is H0. DCI indicates that 2 TBs are scheduled, then H0≠H1, and the HARQ process numbers of the 2 TBs are H0 and H1 respectively. If the NDI of the second TB is 0, then H0 H1. The NDI of the second TB=0, then H0>H1. The NDI of the second TB=1, then H0 <H1。 <h1>

[0384] For example, if DCI schedules 3 TBs, and the NDI of the first TB is 0, the value indicated by the first bit is V=5m+2, where m is 0 or a positive integer. Two bits of the second bit are used to indicate the NDI of the other two TBs except the first TB among the three TBs. There are also two bits in the second bit to indicate the three HARQ process numbers H2 corresponding to the three TBs. For example, H2 is indicated in {012, 013, 023, 123}. Alternatively, two bits of the second bit indicate the NDI of the other two TBs except the first TB among the three TBs. There are also two bits in the second bit to indicate the unscheduled HARQ process number H2 (H2 takes the value of 0, 1, 2, or 3). At this time, the HARQ process numbers corresponding to the three TBs are the remaining three process numbers in {0, 1, 2, 3} except H2.

[0385] For example, if DCI schedules 3 TBs, and the NDI of the first TB is 1, the value indicated by the first bit is V=5m+3, where m is 0 or a positive integer. Two bits of the second bit are used to indicate the NDI of the other two TBs except the first TB among the three TBs. There are also two bits in the second bit to indicate the three HARQ process numbers H2 corresponding to the three TBs. For example, H2 is indicated in {012, 013, 023, 123}. Alternatively, two bits of the second bit indicate the NDI of the other two TBs except the first TB among the three TBs. There are also two bits in the second bit to indicate the unscheduled HARQ process number H2 (H2 takes the value of 0, 1, 2, or 3). At this time, the HARQ process numbers corresponding to the three TBs are the remaining three process numbers in {0, 1, 2, 3} except H2.

[0386] For example, if DCI schedules 4 TBs, the value indicated by the first bit is V=5m+4, where m is 0 or a positive integer. The HARQ process numbers corresponding to the 4 TBs are 0, 1, 2, and 3. The 4 bits of the second bit indicate the NDI corresponding to each of the 4 TBs.

[0387] For example, the following table represents another indication method. In the following table, Ni is the NDI of TBi or the i+1th TB. Where i is 0, 1, 2, 3. For example, V in the following table is the value indicated by the first bit. Floor is a rounding operation. The second bit contains 4 bits: b0, b1, b2, and b3.

[0388]

[0389] Another implementation of the embodiment of the present application is described below from the second node side:

[0390] The second node receives the downlink control information sent by the first node. The second node determines the number of scheduled transport blocks (TBs), the HARQ process number corresponding to each TB, the new data indicator (NDI) of each TB, and the modulation and coding scheme (MCS) index through the received downlink control information. Among them, there are 11 kinds of MCS indexes. The downlink control information includes a first bit and a second bit. The first bit consists of 6 bits, and the second bit consists of 4 bits. The second node also determines the number of scheduled TBs according to the value indicated by the first bit.

[0391] The second node determines the MCS index Imcs according to the value V indicated by the first bit. Where V = Imcs * 5. The second node also determines the number of scheduled TBs according to the value V indicated by the first bit.

[0392] For example, if the value V indicated by the first bit is a multiple of 5, then the downlink control information (DCI) schedules 1 TB or the DCI schedules 2 TBs, and the NDI of the first TB = 0. Two bits in the second bit are used to indicate the first hybrid automatic repeat request (HARQ) process number (H0). Another two bits in the second bit are used to indicate the second HARQ process number (H1). For example, H0 is indicated in {0, 1, 2, 3}. For example, H1 is indicated in {0, 1, 2, 3}. If H0 = H1, then the DCI indicates that 1 TB is scheduled, and the HARQ process number of this TB is H0. If H0 ≠ H1, then the DCI schedules 2 TBs, and the HARQ process numbers of the 2 TBs are H0 and H1 respectively. If H0 < H1, then the NDI of the second TB = 0. If H0 > H1, then the NDI of the second TB = 1. If H0 > H1, then the NDI of the second TB = 0. If H0 < H1, then the NDI of the second TB = 1.

[0393] For example, if the value V indicated by the first bit = 5m + 1, where m is 0 or a positive integer, then the DCI schedules 1 TB or the DCI schedules 2 TBs, and the NDI of the first TB = 1. Two bits in the second bit are used to indicate the first HARQ process number (H0), and another two bits in the second bit are used to indicate the second HARQ process number (H1). For example, H0 is indicated in {0, 1, 2, 3}. For example, H1 is indicated in {0, 1, 2, 3}. If H0 = H1, then the DCI indicates that 1 TB is scheduled, and the HARQ process number of this TB is H0. If H0 ≠ H1, then the DCI schedules 2 TBs, and the HARQ process numbers of the 2 TBs are H0 and H1 respectively. If H0 < H1, then the NDI of the second TB = 0. If H0 > H1, then the NDI of the second TB = 1. If H0 > H1, then the NDI of the second TB = 0. If H0 < H1, then the NDI of the second TB = 1.

[0394] For example, the value V indicated by the first bit is 5m+2, where m is 0 or a positive integer, then the DCI schedules 3 TBs, and the NDI of the first TB is 0. Two bits of the second bit are used to indicate the NDI of the other two TBs in the three TBs except the first TB. There are also two bits in the second bit to indicate the three HARQ process numbers H2 corresponding to the three TBs. For example, H2 is indicated in {012, 013, 023, 123}. Or, there are 2 bits in the second bit to indicate the NDI of the other two TBs in the three TBs except the first TB. There are also two bits in the second bit to indicate the unscheduled HARQ process number H2 (H2 takes the value 0, 1, 2, or 3). At this time, the HARQ process numbers corresponding to the three TBs are the remaining three process numbers in {0, 1, 2, 3} except H2.

[0395] For example, the value V indicated by the first bit is 5m+3, where m is 0 or a positive integer, then the DCI schedules 3 TBs, and the NDI of the first TB is 1. Two bits of the second bit are used to indicate the NDI of the other two TBs in the three TBs except the first TB. There are also two bits in the second bit to indicate the three HARQ process numbers H2 corresponding to the three TBs. For example, H2 is indicated in {012, 013, 023, 123}. Or, there are 2 bits in the second bit to indicate the NDI of the other two TBs in the three TBs except the first TB. There are also two bits in the second bit to indicate the unscheduled HARQ process number H2 (H2 takes the value 0, 1, 2, or 3). At this time, the HARQ process numbers corresponding to the three TBs are the remaining three process numbers in {0, 1, 2, 3} except H2.

[0396] For example, the value indicated by the first bit is V=5m+4, where m is 0 or a positive integer, and the DCI schedules 4 TBs. The HARQ process numbers corresponding to the 4 TBs are 0, 1, 2, and 3. The 4 bits of the second bit indicate the NDI corresponding to each of the 4 TBs.

[0397] The following table shows another indication method. In the following table, Ni is the NDI of TBi or the i+1th TB. Where i is 0, 1, 2, 3. For example, V in the following table is the value indicated by the first bit. Floor is a rounding operation. The second bit contains 4 bits: b0, b1, b2, and b3.

[0398] The second node determines the MCS index by a value obtained by rounding 5 according to the value indicated by the first bit. Imcs=floor(V / 5). The second node determines the number of TBs to be scheduled by a value obtained by modulo 5 according to the value indicated by the first bit.

[0399]

[0400] The value obtained by taking the remainder of the value indicated by the first bit with respect to 5 is 0. The second node determines that the DCI schedules 1 TB or 2 TBs, and determines that the NDI of the first TB is 0. The second node determines the first HARQ process number (H0) according to two bits in the second bit, and the second node determines the second HARQ process number (H1) according to the other two bits in the second bit. If H0 = H1, the second node determines that the DCI schedules 1 TB, and the HARQ process number of this TB is H0. If H0 ≠ H1, the second node determines that the DCI schedules 2 TBs, and the HARQ process numbers of the 2 TBs are H0 and H1 respectively. If H0 < H1, the NDI of the second TB is 0. If H0 > H1, the NDI of the second TB is 1. Or, if H0 > H1, the NDI of the second TB is 0. If H0 < H1, the NDI of the second TB is 1.

[0401] The value obtained by taking the remainder of the value indicated by the first bit with respect to 5 is 1. The second node determines that the DCI schedules 1 TB or 2 TBs, and determines that the NDI of the first TB is 1. The second node determines the first HARQ process number (H0) according to two bits in the second bit, and the second node determines the second HARQ process number (H1) according to the other two bits in the second bit. If H0 = H1, the second node determines that the DCI schedules 1 TB, and the HARQ process number of this TB is H0. If H0 ≠ H1, the second node determines that the DCI schedules 2 TBs, and the HARQ process numbers of the 2 TBs are H0 and H1 respectively. If H0 < H1, the NDI of the second TB is 0. If H0 > H1, the NDI of the second TB is 1. Or, if H0 > H1, the NDI of the second TB is 0. If H0 < H1, the NDI of the second TB is 1.

[0402] The value obtained by taking the remainder of the value indicated by the first bit with respect to 5 is 2. The second node determines that the DCI schedules 3 TBs, and determines that the NDI of the first TB is 0. The second node determines the NDI of the other 2 TBs among the 3 TBs except the first TB according to 2 bits in the second bit. The second node determines the HARQ process number H2 corresponding to the 3 TBs according to the other two bits in the second bit. For example, it indicates H2 in {012, 013, 023, 123}. Or, the second node determines the NDI of the other 2 TBs among the 3 TBs except the first TB according to 2 bits in the second bit. The second node determines the un-scheduled HARQ process number H2 (H2 takes values 0, 1, 2, or 3). At this time, the HARQ process numbers corresponding to the 3 TBs are the remaining 3 process numbers in {0, 1, 2, 3} except H2..

[0403] The value indicated by the first bit is 3 after the modulo operation of 5. The second node determines that the DCI schedules 3 TBs and determines that the NDI of the first TB is 1. The second node determines the NDI of the other 2 TBs in the 3 TBs except the first TB based on 2 bits in the second bit. The second node determines the HARQ process number H2 corresponding to the 3 TBs based on the other two bits in the second bit. For example, H2 is indicated in {012, 013, 023, 123}. Alternatively, the second node determines the NDI of the other 2 TBs in the 3 TBs except the first TB based on 2 bits in the second bit. The second node determines the unscheduled HARQ process number H2 (H2 takes the value 0, 1, 2, or 3) based on the other two bits in the second bit. At this time, the HARQ process numbers corresponding to the 3 TBs are the remaining 3 process numbers in {0, 1, 2, 3} except H2.

[0404] The value indicated by the first bit modulo 5 is 4, and the second node determines that the DCI schedules 4 TBs, and determines that the HARQ process numbers corresponding to the 4 TBs are 0, 1, 2, and 3. The second node determines the NDI corresponding to each TB based on the 4 bits of the second bit.

[0405] 10 bits are used to indicate multi-TB scheduling and other fields in the DCI respectively. Any HARQ process number can be used to indicate multiple TBs for scheduling, and the existing single-TB scheduling method can be supported. However, in essence, only 4 bits are added compared to the existing DCI bit number, and the flexibility of indicating other fields is not affected. While ensuring the flexibility of scheduling, the bit overhead is reduced.

[0406] When scheduling up to 4 TBs, the embodiment of the present application essentially introduces 4 bits for multi-TB scheduling indication. The prior art needs to add at least 5 bits for multi-TB scheduling indication. Therefore, while reducing the bit overhead, the embodiment of the present application can flexibly indicate the HARQ process number of each TB, and can ensure that any number of TBs scheduled by DCI does not affect the flexibility of indicating other fields. It should be noted that for the aforementioned method embodiments, for the sake of simple description, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited to the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously.
