[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] In order to better understand this solution, the relevant concepts involved in this application are first explained:

[0063] HARQ-ACK information:

[0064] In order to ensure the reliability and efficiency of data transmission at the physical layer, LTE adopts HARQ, that is, the data sent can correspond to a transmission block (TB) at the physical layer, and the network device adds a cyclic redundancy check (CRC) to the TB for the terminal to verify whether the TB is successfully received. Furthermore, the TB can be divided into several code blocks (CBs), and the network device can add a corresponding CRC to each CB to verify whether each CB is successfully received. After receiving the data, the terminal attempts to decode the received data. If the CRC of all CBs is successfully checked and the CRC of the TB is successfully checked, a 1-bit TB-level acknowledgement character (ACK) is fed back to the network device to indicate that the data is successfully received; if the CRC check of a certain CB fails or the CRC check of the TB fails, a 1-bit TB-level negative acknowledgement (NACK) is fed back to the network device to indicate that the data reception failed. At this time, the network device needs to retransmit the entire TB.

[0065] Among them, ACK or NACK is called HARQ-ACK information.

[0066] HARQ-ACK feedback codebook:

[0067] The user equipment (UE) can feed back the decoding results (HARQ-ACK information) of multiple data transmitted by the network device to the network device in an uplink control information (UCI), wherein the multiple data may come from different downlink time units and / or different codewords under multiple-input multiple-output (MIMO) and / or different carriers under carrier aggregation, and the decoding result contained in the UCI is the HARQ-ACK feedback codebook.

[0068] Specifically, one UCI may need to feedback HARQ-ACK information of data transmitted in one or more downlink time units, and the feedback downlink time unit set is called the above-mentioned HARQ multiplexing window, wherein the HARQ-ACK feedback codebook is transmitted through the HARQ multiplexing window.

[0069] Time unit:

[0070] In the present application, a time unit may be a subframe, a transmission time interval (wherein a transmission time interval is equal to the sum of several subframe lengths, or the sum of several transmission time intervals is equal to one subframe length), or may be one time domain symbol, multiple time domain symbols, one slot, multiple slots, one mini-slot, multiple mini-slots, or a combination of mini-slots and slots, or a combination of symbols and slots, a combination of mini-slots and slots, etc. The number of symbols / lengths of each time unit is not limited to be the same. If one time unit carries a physical downlink shared channel (PDSCH) or a physical downlink control channel (PDCCH) or UCI, etc., the PDSCH or PDCCH or UCI may not need to completely occupy all time domain symbols and / or frequency domain resources of the time unit.

[0071] Licensed spectrum and unlicensed spectrum:

[0072] For commercial mobile communication systems, operators need to auction the licensed spectrum and obtain authorization before they can use the corresponding spectrum to carry out mobile communication operations. Unlicensed spectrum does not need to be auctioned, and anyone can legally use unlicensed spectrum, such as Wireless Fidelity (WiFi) devices on the 2.4GHz and 5GHz frequency bands. The carrier on the licensed spectrum is called the licensed carrier, and the carrier on the unlicensed spectrum is called the unlicensed carrier. With the development of communication technology, the amount of information transmitted in wireless communication networks is increasing. Seizing the unlicensed spectrum to transmit information can improve the data throughput in the wireless communication network and better meet the needs of users.

[0073] Combine the following Figure 1 The system architecture used by the information processing method provided in this application is briefly described. Figure 1 A system diagram of the information processing method provided in the embodiment of the present application, such as Figure 1 As shown:

[0074] It includes a network device 101 and a user device 102 .

[0075] Among them, the network device 101 is a device with wireless transceiver function. Including but not limited to: Evolutional Node B (eNB or eNodeB) in LTE, base station (gNodeB or gNB) or transmission receiving point / transmission receptionpoin (TRP) in new radio (NR), base station in subsequent evolution system, access node in wireless fidelity (WiFi) system, wireless relay node, wireless backhaul node, etc. The base station can be: macro base station, micro base station, micro-micro base station, small station, relay station, or balloon station, etc. Multiple base stations can support the networks of the same technology mentioned above, or they can support the networks of different technologies mentioned above. The base station can include one or more co-site or non-co-site TRPs. The network device can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The network device can also be a server, a wearable device, or a vehicle-mounted device, etc. 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 or communicate with the terminal through a relay station. The terminal may communicate with multiple base stations of different technologies. For example, the terminal may communicate with a base station supporting an LTE network or a base station supporting a 5G network. It may also support dual connections with base stations of an LTE network and a base station of a 5G network, and may also support dual connections with base stations of a 5G network.

[0076] Among them, the user equipment 102 is a device with wireless transceiver function. The user equipment can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The user equipment can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) user equipment, an augmented reality (AR) user equipment, a wireless terminal in industrial control, a vehicle-mounted user equipment, a wireless terminal in self-driving, a wireless user equipment in remote medical, a wireless user equipment in smart grid, a wireless user equipment in transportation safety, a wireless user equipment in smart city, a wireless user equipment in smart home, a wearable user equipment, etc. The user equipment involved in the embodiments of the present application may also be referred to as a terminal, user equipment (UE), access user equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote user equipment, mobile device, UE user equipment, wireless communication equipment, UE agent or UE device, etc. The user equipment may also be fixed or mobile.

[0077] It is worth noting that the technical solution shown in the present application can be applied to the fifth generation mobile communication technology (5G) system, and can also be applied to the long term evolution (LTE) system, for example, the vehicle to X (V2X) system, device to device (D2D) system, machine type communication (MTC) system, etc. in the LTE communication system, and can also be applied to the universal mobile telecommunications system (UMTS) terrestrial radio access network (UMTS terrestrial radio access network, UTRAN) system, or the global system for mobile communications (GSM) / enhanced data rate for GSM evolution (EDGE) system The radio access network (GSM EDGE radio access network, GERAN) architecture. The technical solution shown in this application can also be applied to other communication systems, such as the evolved communication system of the 5G system, etc. This application is not limited to this, as long as the communication system includes network equipment and user equipment, where the network equipment and the user equipment can exchange information through wireless signals.

[0078] Specifically, in wireless communication systems, such as new radio (NR) communication systems, information exchanged between user equipment and network equipment is carried through physical channels. Among them, the data sent by the user equipment, that is, uplink data, is usually carried by the physical uplink shared channel (PUSCH); the control information sent by the user equipment, that is, uplink control information, is usually carried by the physical uplink control channel (PUCCH). In addition, the user equipment can also send a sounding reference signal (SRS). By receiving the SRS of the user equipment, the network equipment can estimate the channel quality of the user equipment at different frequencies. Accordingly, the data sent by the network equipment to the user equipment can be called downlink data.

[0079] See also Figure 1The network device 101 and the user device 102 may form a communication system, in which the user device 102 may send uplink data to the network device 101, and the network device 101 may send downlink data to the user device 102. It is understandable that the specific number of the network device 101 and the user device 102 may be determined according to the actual scenario. Figure 1 The description is for exemplary purposes only.

[0080] It should be noted that the network architecture described in this application is for the purpose of more clearly illustrating the technical solution of this application, and does not constitute a limitation on the technical solution provided by this application. A person of ordinary skill in the art can know that with the evolution of the network architecture and the emergence of new business scenarios, the technical solution provided by this application is also applicable to similar technical problems.

[0081] Based on the above-mentioned system, the following briefly describes the relevant technical background involved in this application:

[0082] Ultra Reliable & Low Latency Communication (URLLC) services are supported in 5G NR communication systems. The main technologies for 5G URLLC to achieve low latency include: introducing smaller time resource units, such as mini-slots; adopting a scheduling-free permission mechanism for uplink access, so that terminals can directly access the channel; supporting asynchronous processes to save uplink time synchronization overhead; and adopting HARQ and fast dynamic scheduling.

[0083] Currently, the Type 2 HARQ-ACK codebook is the NR dynamic HARQ-ACK codebook, wherein the NR dynamic HARQ-ACK codebook is determined by the downlink assignment index DAI (Downlink Assignment Index, DAI).

[0084] Specifically, the transmission of PDCCH is not completely reliable, and the UE may lose some downlink control information (DCI). For TDD, when some downlink DCI in the HARQ feedback window is lost, ACK may be fed back incorrectly, resulting in a higher HARQ error rate. To avoid such problems, PDCCH introduces a DAI field to tell the UE how many subframes in the HARQ feedback window contain downlink transmissions, which can help the UE detect whether the downlink DCI is lost and avoid the situation where ACK is fed back even though some downlink DCI is lost. DAI can also help the UE determine how many bits of ACK / NACK information need to be fed back.

[0085] In the case where only one carrier is configured, there is one downlink assignment index DAI (Downlink Assignment Index, DAI) in each DCI, and the DAI may also be called a counter downlink assignment index (Counter Downlink Assignment Index, C-DAI).

[0086] The UE may determine the codebook size according to the DCI detected within the HARQ multiplexing window. In one possible implementation, the UE determines the codebook size according to the DAI value of the last detected DCI to arrange the HARQ-ACK information at a position corresponding to the DAI value in the DCI.

[0087] For the case where more than one carrier is configured, there are two DAIs in each DCI (one is C-DAI and the other is Total Downlink Assignment Index (T-DAI), where the T-DAI of all carriers on one time unit is equal.

[0088] It should be noted that the names of the above T-DAI and C-DAI may not be limited to T-DAI and C-DAI in specific applications, as long as they can achieve the number of indexed time units. In addition, in a specific implementation, it is not necessary to have both T-DAI and C-DAI at the same time, and only one DAI may be needed, which is called DAI. This method is particularly suitable for application scenarios where each carrier determines HARQ-ACK information or only one carrier is configured.

[0089] Currently, in the Licensed-Assisted Access Using Long Term Evolution (LAA-LTE) system, data transmission in unlicensed spectrum requires a listen before talk (LBT) mechanism to use channel resources to reduce the impact on other systems.

[0090] Specifically, in the licensed spectrum, the network equipment can determine the uplink resources occupied by the UE to send the uplink feedback information to determine the time of the uplink feedback information. However, in the unlicensed spectrum, because the UE accesses by itself through the LBT mechanism, the network equipment cannot determine the time of the uplink feedback, which will cause the PDSCH and the uplink feedback channel to be in different continuous occupancy times (Continuous Occupy Time, COT). Based on this, NR-U introduces an enhanced dynamic codebook feedback scheme to solve the problem of different continuous occupancy times of the PDSCH and the uplink feedback channel.

[0091] In the enhanced dynamic codebook feedback solution, the DCI may include PDSCH group signaling (group index), whether it is a new ACK feedback group indication (New ACK-Feedback Group Indicator, NFI), whether a non-scheduled PDSCH group is triggered, and other information.

[0092] Among them, PDSCH group signaling is used to indicate the grouping of PDSCH, and in this embodiment, NFI is used to indicate whether the PDSCH group is a new group. Specifically, it is whether it is a new group compared with the PDSCH group before the current time unit. Assuming that the PDSCH group before the current time unit is group 0, and the PDSCH group of the current time unit is group 1, then NFI indicates that the current PDSCH group is a new group; or, assuming that the PDSCH group before the current time unit is group 0, and the PDSCH group of the current time unit is group 0, then NFI indicates that the current PDSCH group is not a new group.

[0093] In addition, since the downlink scheduling DCI cannot determine the specific time of HARQ-ACK feedback in some scenarios (such as exceeding the current maximum occupancy time of the downlink channel), a non-numerical value K1 can be used to indicate the feedback time, where K1 is the PDSCH-to-HARQ timing indicator (PDSCH-to-HARQ-timing-indicator).

[0094] For the enhanced dynamic codebook, when the HARQ-ACK timing indication of a PDSCH is a non-numeric value K1, the specific K1 is obtained by the feedback triggered by the value K1 in the next downlink DCI and including the PDSCH group.

[0095] And in 5G NR, K0 can be used to represent the time interval between PDCCH and PDSCH. Figure 2 Introduce K0 and K1. Figure 2 Schematic diagram of K0 and K1 provided in an embodiment of the present application.

[0096] See also Figure 2 , Figure 2 The 5th time unit includes 5 time units, including DCI in the first time unit, PDSCH in the second time unit, and ACK / NACK in the fifth time unit. In 5G NR, K0 is used to identify the time interval between PDCCH and PDSCH, where PDCCH is used to transmit DCI and PDSCH is used to transmit downlink data. Figure 2 It can be determined from the example that the time interval between DCI and PDCCH is 1 time unit, then K0 can be 1 time unit, such as Figure 2 As shown in K0.

[0097] And, in 5G NR, K1 is used to identify the time interval between PDSCH and ACK / NACK, see Figure 2 It can be determined from the example that the time interval between PDSCH and ACK / NACK is 3 time units, then K1 can be 3 time units, such as Figure 2 As shown in K1.

[0098] In a possible implementation, the units of K0 and K1 may be time slots. In the actual implementation process, the specific settings of K0 and K1 may be configured by the network device according to actual needs. This embodiment does not limit the specific settings of K0 and K1.

[0099] The following is a brief introduction to the relevant background technology of power control:

[0100] DCI includes multiple formats. DCI information in different formats can be used for different purposes. For example, there is DCI for allocating downlink RB resources, there is DCI for allocating uplink RB resources, there is DCI for adjusting uplink power control, and there is DCI specifically for downlink dual-stream spatial division multiplexing. The protocol classifies DCI for different purposes and distinguishes them with different DCI formats.

[0101] In a possible implementation, DCI format 0_1 ​​is used for information such as uplink PUSCH scheduling of a cell, wherein the DCI format 0_1 ​​may include, for example, a carrier indication, an uplink (UL) / supplementary uplink (SUL) indication, and the like.

[0102] In a possible implementation, the DCI format 0_1 ​​may include a field “DFI flag”, where the field “DFI flag” may be used to indicate whether the current DCI is used to carry configured grant downlink feedback information (Configured Grant Downlink Feedback Information, CG-DFI).

[0103] Among them, the field "DFI flag" can be 1 bit. When the field "DFI flag" is set to 1, it can indicate that the current DCI is used to carry CG-DFI. At this time, the bits after CG-DFI in the DCI can be set as shown below. The original English protocol is attached below:

[0104] -HARQ-ACK bitmap – 16 bits, where the order of bitmap to HARQ process index mapping is such that the HARQ process index is mapped in ascending order from the Most Significant Bit (MSB) of the bitmap to the Linux Standards Base (LSB). For each bit of the bitmap, a value of 1 indicates ACK and a value of 0 indicates NACK.

[0105] (HARQ-ACK bitmap–16bits,where the order of the bitmap to HARQ processindex mapping is such that HARQ process indices are mapped in ascending order from MSB to LSB of the bitmap.For each bit of the bitmap,value1indicates ACK,and value 0indicates NACK.)

[0106] - Transmit Power Control (TPC) command for scheduled PUSCH – 2 bits, as defined in clause 7.1.1 of [5, TS38.213]

[0107] (-TPC command for scheduled PUSCH–2bits as defined in Clause 7.1.1of[5,TS38.213])

[0108] - All remaining bits of format 0_1 ​​are set to zero.

[0109] (All the remaining bits in format 0_1are set to zero)

[0110] The TPC command is used to indicate the adjustment of power. In DCI format 0_1, the TPC command is 2 bits, which can be used to indicate the power adjustment amount, thereby indicating how much the power is increased, or how much the power is reduced, or it can also indicate that the power remains unchanged.

[0111] Currently, TPC commands can be carried in DCI. Power control can be divided into open-loop power control and closed-loop power control. Open-loop power control refers to power control based on its own measurements without the need for feedback information from the receiving end. Closed-loop power control refers to the transmitter controlling the transmit power based on the feedback information sent by the receiving end.

[0112] For the uplink, the closed-loop power control of the uplink means that the network equipment determines the TPC command based on the measurement results of the channel quality of the SRS and demodulation reference signal (DMRS) reported by the terminal equipment and the power headroom report (PHR) reported by the terminal equipment and other related statistics, and sends the TPC command to the terminal equipment. The terminal equipment then adjusts the power according to the received TPC command.

[0113] Among them, the open-loop power control of the uplink means that the terminal device determines the size of the transmission power by itself without the need for input from the network device.

[0114] Currently, the Physical Random Access Channel (PRACH) in the uplink can adopt open-loop power control, and all channels except PRACH can adopt closed-loop power control.

[0115] Based on the above-mentioned related background technologies, the implementation scheme of the prior art involved in this application and the problems of the prior art are described below:

[0116] First combine Figure 3 The problem of out-of-order execution (OoO) of HARQ-ACK feedback of different priority data in the prior art is introduced. Figure 3 A schematic diagram of the implementation of PDSCH triggered HARQ-ACK feedback provided in this application.

[0117] See also Figure 3 , Figure 3 It includes two COTs (continuous occupation times). In the first COT, it includes two PDSCHs, namely PDSCH1 and PDSCH2.

[0118] Among them, PDSCH1 is triggered by PDCCH1, PDSCH1 belongs to group 1, the HARQ-ACK feedback time of PDSCH1 is non-numerical K1 (NNK), and its feedback priority is low priority.

[0119] Among them, PDSCH2 is triggered by PDCCH2, PDSCH2 belongs to group 1, the HARQ-ACK feedback time of PDSCH2 is non-numerical K1 (NNK), and its feedback priority is high priority.

[0120] Based on the above, it can be introduced that K1 is a non-numeric value, and the specific value of K1 depends on the next numerical value of K1.

[0121] The second COT includes two PDSCHs, namely PDSCH3 and PDSCH4.

[0122] Among them, PDSCH3 is triggered by PDCCH3, PDSCH3 belongs to group 2, the HARQ-ACK feedback time of PDSCH3 is the value K1, and its feedback priority is low priority.

[0123] Among them, PDSCH4 is triggered by PDCCH4, PDSCH4 belongs to group 2, the HARQ-ACK feedback time of PDSCH4 is a value K1, and its feedback priority is high priority.

[0124] Among them, because the priorities of PDSCH3 and PDSCH1 are both low priorities, and K1 of PDSCH3 is numerical, while the priority of PDSCH1 is non-numerical, PDSCH3 can trigger the HARQ-ACK of PDSCH1 and PDSCH3 to be fed back together, that is, through Figure 3 The PUCCH1 in the communication channel feeds back the HARQ-ACK of both parties together.

[0125] And, because the priorities of PDSCH4 and PDSCH2 are both high priorities, and K1 of PDSCH4 is numerical, while the priority of PDSCH2 is non-numerical, PDSCH4 can trigger the HARQ-ACK of PDSCH2 and PDSCH4 to be fed back together, that is, through Figure 3 The PUCCH2 in the communication channel feeds back the HARQ-ACK of both parties together.

[0126] However, in one possible implementation, if there is no scheduling of PDSCH3, that is, there is no low-priority PDSCH scheduling, there will be no low-priority HARQ-ACK, which will result in PUCCH1 not being sent, but PUCCH2 being sent, resulting in the high-priority HARQ-ACK PUCCH2 being fed back earlier than the low-priority HARQ-ACK PUCCH1, because the low-priority PDSCH1 is sent earlier and the high-priority PDSCH2 is sent later, so the above-mentioned HARQ-ACK feedback situation is not allowed, that is to say, there is a disorder problem of HARQ-ACK feedback of different priority data in the prior art.

[0127] Another problem with the prior art is that only one TPC information can be indicated in the CG-DFI. Because only one authorized scheduling PUSCH was supported in the non-authorized mode, there is no need to specifically indicate which PUSCH the TPC signaling is used for power control.

[0128] However, the configuration of multiple granted scheduled PUSCHs can now be supported, resulting in that when the HARQ-ACK of multiple granted scheduled PUSCHs is fed back in the CG-DFI, it is unable to clearly indicate how the power control of multiple granted scheduled PUSCHs is performed.

[0129] In response to the above-mentioned problems, the present application provides an information processing method to effectively solve the OoO problem of HARQ-ACK feedback of data of different priorities, and can clarify the implementation method of power control of PUSCHs of multiple authorization scheduling. The method provided by the present application is introduced below in combination with specific embodiments.

[0130] First combine Figure 4 The implementation method of solving the disorder problem of HARQ-ACK feedback of different priorities in this application is introduced. Figure 4 A flowchart of an information processing method provided in an embodiment of the present application, Figure 5 A schematic diagram of the implementation of DCI triggered HARQ-ACK feedback provided in this application.

[0131] like Figure 4 As shown, the method includes:

[0132] S401. Receive downlink control information DCI sent by a network device, where the DCI includes at least one of the following information: a first priority and a first group identifier.

[0133] During the communication process between the terminal device and the network device, in order to receive PDSCH or send PUSCH, the terminal device generally needs to receive DCI sent by the network device, where the DCI can indicate all the information required for the terminal device to receive PDSCH or send PUSCH.

[0134] In this embodiment, in order to avoid the disorder problem in the HARQ-ACK feedback process, the DCI in this embodiment may include a first priority and a first group identifier to trigger the feedback of the HARQ-ACK of the scheduled PDSCH corresponding to the first priority and the first group identifier.

[0135] The first group identifier is used to indicate the PDSCH group corresponding to the scheduled PDSCH, and the first priority is used to indicate the priority of the scheduled PDSCH.

[0136] Here, the PDSCH group is explained. In LTE, the PDSCH is currently divided into group 0 (Type 0) and group 1 (Type 1).

[0137] Group 0 is allocated by group during allocation, and the bitmap sent to the UE indicates which group is used, wherein the size of the group is related to the number of bandwidth resource blocks (RBs).

[0138] Group 1 defines the system bandwidth into several subsets. When allocating to a UE, the target subset is indicated, and then one or some RBs in the target subset are indicated as usable.

[0139] In a possible implementation, the first group identifier may be 0 to indicate that the PDSCH group corresponding to the scheduled PDSCH is group 0; or, the first group identifier may be 1 to indicate that the PDSCH group corresponding to the scheduled PDSCH is group 1.

[0140] Alternatively, the first group identifier may also be indication information that has a mapping relationship with group 0 and group 1, for example, it may be a binary implementation form, or it may also be a corresponding mapping letter, etc. This embodiment does not impose any limitation on this.

[0141] In addition, if there are more PDSCH groups in LTE later, for example, there are further group 2, group 3, etc., then the first group identifier may correspond to 2, 3, etc., which is not limited in this embodiment.

[0142] In this embodiment, the first priority included in the DCI is used to indicate the priority of the scheduled PDSCH, which may be, for example, high priority / low priority, or may be first-level priority / second-level priority / third-level priority and other priorities, depending on the implementation form of the priority, which is not limited here.

[0143] S402: Send, according to the DCI, a hybrid automatic repeat request-acknowledgement HARQ-ACK feedback of a physical downlink shared channel PDSCH corresponding to the first priority and the first group identifier to a network device.

[0144] In this embodiment, in order to avoid the above-mentioned disorder problem of HARQ-ACK, the network device triggers HARQ-ACK feedback of the PDSCH corresponding to the first priority and the first group identifier according to the instruction of the DCI.

[0145] In a possible implementation manner, the DCI sent by the network device may further include frequency domain resource allocation information, wherein the field of the frequency domain resource allocation information in the DCI may be, for example, Frequency domain resourceassignment.

[0146] Then, the frequency domain resource allocation information may be set to a preset value, thereby triggering HARQ-ACK feedback of the PDSCH corresponding to the first priority and the first group identifier.

[0147] In one possible implementation, the preset value of the frequency domain resource allocation information may be, for example, all 0s, or the frequency domain resource allocation information may be, for example, all 1s, or the frequency domain resource allocation information may also be a preset combination of 0 and 1, etc. This embodiment does not limit the specific implementation method of the preset value of the frequency domain resource allocation information, and it can be selected based on actual needs, as long as a preset value is preset and the corresponding HARQ-ACK feedback can be triggered by the preset value.

[0148] Alternatively, in another possible implementation, the DCI may further include indication information, where the indication information is used to trigger HARQ-ACK feedback for the PDSCH corresponding to the first priority and the first group identifier.

[0149] The following takes the frequency domain resource allocation information as a preset value as an example. Figure 5 To understand the implementation process of triggering HARQ-ACK feedback, see Figure 5 , Figure 5 It includes two COTs (continuous occupation times). In the first COT, it includes two PDSCHs, namely PDSCH1 and PDSCH2.

[0150] Among them, PDSCH1 is triggered by PDCCH1, PDSCH1 belongs to group 1, the HARQ-ACK feedback time of PDSCH1 is non-numerical K1 (NNK), and its feedback priority is low priority.

[0151] Among them, PDSCH2 is triggered by PDCCH2, PDSCH2 belongs to group 1, the HARQ-ACK feedback time of PDSCH2 is non-numerical K1 (NNK), and its feedback priority is high priority.

[0152] Based on the above, it can be introduced that K1 is a non-numeric value, and the specific value of K1 depends on the next numerical value of K1.

[0153] The second COT includes a PDSCH, specifically PDSCH3.

[0154] Among them, PDSCH3 is triggered by PDCCH3, PDSCH3 belongs to group 2, the HARQ-ACK feedback time of PDSCH3 is the value K1, and its feedback priority is high priority.

[0155] Because the priorities of PDSCH3 and PDSCH2 are both high, and the K1 of PDSCH3 is numerical, while the priority of PDSCH2 is non-numerical, PDSCH3 can trigger the HARQ-ACK of PDSCH2 and PDSCH3 to be fed back together, that is, through Figure 5 The PUCCH2 in the communication channel feeds back the HARQ-ACK of both parties together.

[0156] At this time, in order to avoid the HARQ-ACK of the high-priority PDSCH2 being fed back earlier than the HARQ-ACK of the low-priority PDSCH1, the network device can send a DCI to the terminal device, the first priority in the DCI can be a low priority, and the first group identifier can be group 1.

[0157] In this implementation, the DCI has no data scheduling, but instead triggers the terminal device to perform HARA-ACK feedback of PDSCH1 corresponding to low priority and group 1 by setting the frequency domain resource allocation information to a preset value. This ensures that even though there is no low priority PDSCH scheduling at present, it can still ensure that the PUCCH1 of the low priority HARQ-ACK is fed back earlier than the PUCCH2 of the high priority HARQ-ACK, thereby effectively solving the disorder problem of HARQ-ACK feedback of data of different priorities.

[0158] In one possible implementation, for example, the first time length can be configured in the DCI, and the first time length can be, for example, K1, wherein the first time length is used to indicate that the HARQ-ACK of PDSCH1 is fed back before the HARQ-ACK of PDSCH2, and the specific setting method of the first time length can be selected according to actual needs, as long as the sequential feedback of HARQ-ACK can be achieved.

[0159] It should be noted that, in the actual implementation process, the time when the network device sends the DCI can be selected according to actual needs. Figure 5 In the example, the DCI is sent after PDSCH3, and it may also be sent before PDSCH3. This embodiment does not impose any limitation on this, as long as the DCI can trigger the corresponding HARQ-ACK feedback to ensure the sequential feedback of HARQ-ACK for data of different priorities.

[0160] It can be understood that in the actual implementation process, the DCI may also include relevant information for indicating HARQ-ACKA feedback, such as K1 and NFI introduced above. Therefore, all relevant information for indicating HARQ-ACKA feedback can be used as the information included in the DCI in this embodiment. This embodiment does not impose any special restrictions on the specific implementation method of DCI.

[0161] At the same time, the first group identifier and the first priority included in the DCI are determined by the network device according to the current need to trigger the PDSCH of HARQ-ACK feedback through DCI. For example, it can be the PDSCH1 introduced above. There is no corresponding first priority PDSCH scheduling to trigger HARQ-ACK feedback, so the DCI in this embodiment is required to trigger it, or it can also be the PDSCH that needs to be triggered by DCI for feedback determined by the network device according to special needs. This embodiment does not limit the implementation method of the first group identifier and the first priority.

[0162] In another possible implementation, if the network device determines that there is currently no need to perform the special HARQ-ACK trigger provided in this embodiment on the PDSCH data, for example, the PDSCH corresponding to the first priority and the first group identifier can perform HARQ-ACK feedback sequentially, then the frequency domain resource allocation information can be set not to the preset value to perform normal HARQ-ACK triggering.

[0163] The information processing method provided by the embodiment of the present application includes: receiving downlink control information DCI sent by a network device, wherein the DCI includes at least one of the following information: a first priority and a first group identifier. According to the DCI, a hybrid automatic repeat request-acknowledgement reply HARQ-ACK feedback of a physical downlink shared channel PDSCH corresponding to the first priority and the first group identifier is sent to the network device. The DCI is not triggered by the indication of the DCI, but the HARQ-ACK feedback of the PDSCH corresponding to the first priority and the first group identifier is triggered, so as to effectively realize that in the absence of PDSCH scheduling of the first priority value K1, the HARQ-ACK feedback of the PDSCH of the first priority can also be realized, so as to ensure the sequential feedback of the HARQ-ACK of data of different priorities.

[0164] Based on the above embodiment, the following is an introduction to possible implementation methods of the preset value of the frequency domain resource allocation information in the present application. In this embodiment, the frequency domain resource allocation information includes at least one bit:

[0165] If the DCI format only supports type 0 resource allocation (ie, indicating available PRBs by means of a bitmap), the frequency domain resource allocation information is preset to: all bits of the frequency domain resource allocation information are 0, that is, the frequency domain resource allocation information is set to all 0.

[0166] If the DCI format only supports type 1 resource allocation (i.e., indicating available PRBs by indicating the starting position and length of resources), the frequency domain resource allocation information is preset to: all bits of the frequency domain resource allocation information are 1, that is, the frequency domain resource allocation information is set to all 1s.

[0167] If the DCI format supports both the type 0 resource allocation described above and the type 1 resource allocation, the frequency domain resource allocation information is preset to: all bits of the frequency domain resource allocation information are 1, or all bits of the frequency domain resource allocation information are 0. That is, the frequency domain resource allocation information is set to all 1 or all 0.

[0168] In addition, if the control information supports one-shot HARQ-ACK feedback (type 3 HARQ-ACK codebook), the first field may be set to 0, where the first field is a one-shot HARQ-ACK request field (One-shot HARQ-ACK request).

[0169] The information processing method provided in the embodiment of the present application can effectively solve the disorder problem of HARQ-ACK of different priorities.

[0170] At the same time, the information processing method provided by the present application can also effectively indicate power control. Figure 6 The implementation method of power control is described. Figure 6 A flowchart of an information processing method provided by another embodiment of the present application.

[0171] like Figure 6 As shown, the method includes:

[0172] S601. Receive downlink control information DCI sent by a network device, wherein if the first field in the DCI used to indicate downlink feedback information DFI is preset data, the DCI also includes indication information, and the indication information is used to indicate the transmission power control TPC and / or the closed loop corresponding to the TPC.

[0173] In this embodiment, if the configuration information (configuredgrantconfig) of a configuration grant PUSCH of the terminal device contains information about powerControlLoopToUse (power control loop to be used), it can be determined which loop the current configuration grant PUSCH corresponds to. In one possible implementation method, there may be two loops, or in a possible implementation method, there may be more than two loops, and the implementation method may be adaptively expanded with reference to the implementation method of the two loops.

[0174] In this embodiment, if the first field in the DCI for indicating the downlink feedback information DFI is preset data, the DCI in this embodiment also includes indication information, wherein the indication information is used to indicate the transmission power control TPC and / or the closed loop corresponding to the TPC.

[0175] The first field may be, for example, the DFI flag introduced in the above embodiment, and the first field as preset data may be: DFI flag=1, indicating that the current DCI is used to carry CG-DFI.

[0176] In this embodiment, in order to clearly indicate how the TPC command implements power control of multiple configured authorized PDSCHs, the DCI in this embodiment may include indication information in addition to the existing fields, wherein the indication information is used to indicate TPC and / or indicate the closed loop corresponding to TPC.

[0177] In a possible implementation manner, the indication information is used to indicate the index of the closed loop, and the indication information is 1 bit.

[0178] For example, the indication information may be closed loop index information (Closed loop indicator). Since there are two loops, the closed loop index information may be 1 bit, thereby effectively indicating which loop the TPC command corresponds to, and the configuration information of the PUSCH includes the information of powerControlLoopToUse, thereby effectively implementing the power control of the corresponding PUSCH.

[0179] The closed-loop index information and the TPC command may be, for example, as follows:

[0180] Closed loop indicator–1 bit.

[0181] TPC command–2 bits

[0182] Closed loop indicator–1 bit.

[0183] TPC command–2 bits

[0184] If there are more than two loops, the number of bits of the closed-loop index information may be increased accordingly.

[0185] In another possible implementation, the TPC commands of all closed-loop indication index information may be arranged in the order of the closed-loop indication index, for example, the indication information includes at least two sub-indication information, wherein each sub-indication information is used to indicate the TPC of the corresponding closed loop.

[0186] For example, if there are currently two closed loops, the indication information may include first sub-indication information and second sub-indication information, wherein the first sub-indication information is used to indicate the TPC of the first closed loop, and the second sub-indication information is used to indicate the TPC of the second closed loop. The first sub-indication information and the second sub-indication information are both 2 bits.

[0187] It can be understood that, assuming that there are two loops, represented by loop0 and loop1 respectively, the first sub-indication information can be used to indicate the TPC of the first closed loop loop0, for example, and the second sub-indication information can be used to indicate the TPC of the second closed loop loop2, for example. The original TPC is 2 bits, so the first indication information and the second indication information are also 2 bits, and the implementation method thereof can be, for example:

[0188] TPC command for Closed loop indicator 0–2bits

[0189] TPC command for Closed loop indicator 1–2bits

[0190] Among them, TPC command for Closed loop indicator 0 is the TPC command for the first closed loop loop0, and TPC command for Closed loop indicator 1 is the TPC command for the second closed loop loop1. The indication method is the same as the TPC command introduced above, except that the TPC corresponding to each closed loop is indicated in decibels, so that the power control of the corresponding PUSCH can be effectively implemented.

[0191] Alternatively, when there are more than two closed loops, the indication information correspondingly includes more than two sub-indication information, and its implementation method is similar to the implementation method of the two closed loops introduced above, and only needs to be expanded accordingly.

[0192] S602: Adjust the transmit power according to the instruction information.

[0193] The indication information in this embodiment can indicate the TPC corresponding to each closed loop. Then, according to the indication information, the transmission power of the channel corresponding to the closed loop can be adjusted. For example, the transmission power can be indicated to be increased, or the transmission power can be indicated to be decreased, or the transmission power can be indicated to remain unchanged. The specific power adjustment depends on the indication of TPC, and this embodiment does not limit this.

[0194] The information processing method provided by the embodiment of the present application includes: receiving downlink control information DCI sent by a network device, wherein if the first field in the DCI used to indicate downlink feedback information DFI is preset data, the DCI also includes indication information, and the indication information is used to indicate the transmission power control TPC and / or the closed loop corresponding to TPC. The transmit power is adjusted according to the indication information. The TPC and / or the closed loop corresponding to TPC are indicated by the indication information in the DCI, so that the power control of each PUSCH can be effectively realized while supporting the configuration of multiple authorization scheduling PUSCHs.

[0196] The receiving module 701 is configured to receive downlink control information DCI sent by a network device, wherein the DCI includes at least one of the following information: a first priority and a first group identifier;

[0197] The sending module 702 is used to send a hybrid automatic repeat request-acknowledgement HARQ-ACK feedback of the physical downlink shared channel PDSCH corresponding to the first priority and the first group identifier to a network device according to the DCI.

[0199] The sending module 702 is specifically used for:

[0209] In one possible design, the first type of resource allocation is a resource allocation that indicates available resources by means of a bitmap, and the second type of resource allocation is a resource allocation that indicates available resources by indicating a starting position and a length.
