Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

For a better understanding of the present solution, the related concepts referred to in the present application are explained first:

HARQ-ACK information:

in order to ensure reliability and transmission efficiency of data transmission of a physical layer, the LTE employs HARQ, that is, transmitted data may correspond to a Transport Block (TB) in the physical layer, and the network device adds a Cyclic Redundancy Check (CRC) to the TB to Check whether the TB is successfully received by the terminal. Further, the TB may be further divided into several Code Blocks (CBs), and the network device may add a corresponding CRC to each CB for checking whether each CB is successfully received. After receiving the data, the terminal tries to decode the received data, and if the CRC of all CBs is successful and the CRC of the TB is successful, 1-bit TB-level Acknowledgement Character (ACK) information is fed back to the network equipment to indicate that the data is successfully received; if there is a CRC failure of a CB or a CRC failure of the TB, a 1-bit TB-level Negative Acknowledgement (NACK) message is fed back to the network device to indicate a data reception failure. At this point, the network device needs to retransmit the entire TB.

Here, ACK or NACK is referred to as HARQ-ACK information.

HARQ-ACK feedback codebook:

user Equipment (UE) may feed back, to the network device, a decoding result (HARQ-ACK Information) of Multiple data transmitted by the network device in Uplink Control Information (UCI), where the Multiple data may be from different downlink time units and/or different carriers under Multiple-Input Multiple-Output (MIMO) and different codewords and/or different carriers under carrier aggregation, and the decoding result included in the UCI is an HARQ-ACK feedback codebook.

Specifically, 1 UCI may need to feed back HARQ-ACK information of data transmitted in 1 or more downlink time units, and a set of downlink time units fed back is referred to as the HARQ multiplexing window, where the HARQ-ACK feedback codebook is transmitted through the HARQ multiplexing window.

Time unit:

in this application, a time unit may be a subframe, a transmission time interval (where one transmission time interval is equal to the length of several subframes and/or the sum of several transmission time intervals is equal to the length of one subframe), or may be 1 time domain symbol, multiple time domain symbols, 1 slot (slot), multiple slots, 1 mini-slot (mini-slot), multiple mini-slots, or a combination of a mini-slot and a slot, or a combination of a symbol and a slot, a mini-slot and a slot, or the like, and the number of symbols/the length of each time unit is not limited to be the same. If 1 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 fully occupy all time domain symbols and/or frequency domain resources of the time unit.

Licensed spectrum (licensed spectrum) and unlicensed spectrum (unlicensed spectrum):

for a commercial mobile communication system, an operator needs to auction authorized spectrum, and can use the corresponding spectrum to perform mobile communication operation activities after obtaining authorization. Unlicensed spectrum does not require auctioning and anyone can legally use unlicensed spectrum, such as Wireless Fidelity (WiFi) devices in the 2.4GHz and 5GHz bands. The carriers on the licensed spectrum are referred to as licensed carriers and the carriers on the unlicensed spectrum are referred to as unlicensed carriers. With the development of communication technology, the amount of information transmitted in a wireless communication network is increasing day by day, and the unauthorized spectrum transmission information is preempted, so that the data throughput in the wireless communication network can be improved, and the requirements of users can be better met.

The base station may contain one or more co-sited or non co-sited TRPs. The network device may 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 may also be a server, a wearable device, or a vehicle mounted device, etc. The following description will take a network device as an example of a base station. The multiple network devices may be base stations of the same type or different types. The base station may communicate with the terminal, or may communicate with the terminal through the relay station.

It should be noted that The technical solution shown in The present application can be applied to The 5th Generation mobile communication technology (5G for short) system, and can also be applied to Long Term Evolution (LTE) system, for example, a vehicle to all (V2X) system, a device to device (D2D) system, a Machine Type Communication (MTC) system, etc. in the LTE communication system, may also be applied to a Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (UTRAN) system, or a radio access network (GERAN) architecture of a global system for mobile communication (GSM)/enhanced data rate for GSM evolution (EDGE) system. The technical solution shown in the present application may also be applied to other communication systems, for example, an evolved communication system of a 5G system, and the like, and the present application does not limit this, as long as the communication system includes a network device and a user equipment, where the network device and the user equipment may perform information interaction through a wireless signal.

Specifically, in a wireless communication system, such as a New Radio (NR) communication system, information exchanged between a user equipment and a network device is carried through a physical channel. Data sent by the ue, that is, uplink data, is usually carried through a Physical Uplink Shared Channel (PUSCH); control information, i.e., uplink control information, transmitted by the ue is usually carried through a Physical Uplink Control Channel (PUCCH). In addition, the ue may also send a Sounding Reference Signal (SRS), and the network device may estimate channel qualities of the ue on different frequencies by receiving the SRS of the ue. Accordingly, the data transmitted by the network device to the user equipment may be referred to as downlink data.

Referring to fig. 1, a network device 101 and a 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 understood that the specific number of the network devices 101 and the user devices 102 may be determined according to actual situations, and is only an exemplary illustration in fig. 1.

It should be noted that the network architecture described in the present application is for more clearly illustrating the technical solution of the present application, and does not constitute a limitation to the technical solution provided in the present application, and as a person having ordinary skill in the art knows, along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the present application is also applicable to similar technical problems.

On the basis of the system described above, the following is a brief description of the related art background to which this application relates:

high-reliability low-latency (URLLC) service is supported in a 5G NR Communication system. The main technologies for realizing low delay by the 5G URLLC include: introducing smaller time resource units, such as a mini-slot (mini-slot); the uplink access adopts a mechanism without scheduling permission, and the terminal can directly access a channel; an asynchronous process is supported to save uplink time synchronization overhead; HARQ and fast dynamic scheduling are adopted.

Currently, the HARQ-ACK codebook of Type2 is an NR dynamic HARQ-ACK codebook, wherein the determination of the NR dynamic HARQ-ACK codebook is determined by a Downlink Assignment Index (DAI).

Specifically, the transmission of PDCCH is not completely reliable, and the UE may lose some Downlink Control Information (DCI), and for TDD, when some Downlink DCI in the HARQ feedback window is lost, ACK may be fed back erroneously, which results in high HARQ error rate. In order to avoid such problems, the PDCCH introduces a DAI field to tell the UE how many subframes contain downlink transmissions in the HARQ feedback window, so as to help the UE detect whether downlink DCI is lost, and avoid the situation that some downlink DCI is lost but ACK is fed back, and the DAI can help the UE determine how many bits of ACK/NACK information need to be fed back.

In the case where only 1 carrier is allocated, 1 Downlink Assignment Index (DAI) exists in each DCI, and this DAI may be referred to as a Counter Downlink Assignment Index (C-DAI).

The UE may determine the codebook size according to the DCI detected in the HARQ multiplexing window, and in a possible implementation, the UE determines the codebook size according to the DAI value of the last detected DCI, so as to arrange the HARQ-ACK information to a position corresponding to the DAI value in the DCI.

For the case of configuring more than 1 carrier, two DAIs (one is C-DAI, and the other is Total Downlink Assignment Index (T-DAI)) exist in each DCI, wherein the T-DAIs of all carriers on 1 time unit are equal

It should be noted that the names of the above T-DAI and C-DAI in specific applications may not be limited to T-DAI and C-DAI, as long as they enable the indexing of the number of time units. In addition, in a specific implementation scheme, the T-DAI and the C-DAI do not need to exist at the same time, only 1 DAI is needed, and the method is particularly suitable for application scenarios in which each carrier determines HARQ-ACK information or only 1 carrier is configured.

Currently, in a Long-Term Evolution-Assisted Access Using Long Term Evolution (LAA-LTE) system, data transmission of an unlicensed spectrum requires a Listen Before Talk (LBT) mechanism to use channel resources, so as to reduce the influence on other systems.

Specifically, in the authorized spectrum, the network device may determine the uplink resource occupied by the UE for sending the uplink feedback information to determine the Time of the uplink feedback information, however, in the unauthorized spectrum, because the UE is self-accessed through an LBT mechanism, the network device cannot determine the Time of the uplink feedback, which may cause the PDSCH and the uplink feedback channel to be in different Continuous occupancy durations (COTs), based on which, the NR-U introduces an enhanced dynamic codebook feedback scheme to solve the problem that the PDSCH and the uplink feedback channel are in different Continuous occupancy durations.

In the enhanced dynamic codebook Feedback scheme, the DCI may include information such as a PDSCH Group signaling (Group index), whether the DCI is a New ACK-Feedback Group Indicator (NFI), whether an unscheduled PDSCH Group is triggered, and the like.

The PDSCH group signaling is used to indicate the grouping of the PDSCH, and the NFI in this embodiment is used to indicate whether the PDSCH group is a new group, specifically, whether the PDSCH group is a new group compared to 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 before the current time unit is group 1, the 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, the NFI indicates that the current PDSCH group is not a new group.

In addition, since the downlink scheduling DCI cannot determine the specific time for HARQ-ACK feedback in some scenarios (e.g., exceeding the maximum occupied duration of the current downlink channel), a non-value K1 may be used to indicate the feedback time, where K1 is a PDSCH-to-HARQ-timing-indicator (PDSCH-to-HARQ-timing-indicator).

For the enhanced dynamic codebook, when the HARQ-ACK timing indication of one PDSCH is a non-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.

And in 5G NR, K0 may be used to indicate a time interval between a PDCCH and a PDSCH, where K0 and K1 are described below with reference to fig. 2, and fig. 2 is a schematic diagram of K0 and K1 provided in this embodiment of the present application.

Referring to fig. 2, fig. 2 includes 5 time units, DCI in the 1 st time unit, PDSCH in the second time unit, ACK/NACK in the 5th time unit, and K0 is used to identify a time interval between PDCCH and PDSCH in 5G NR, where PDCCH is used to transmit DCI and PDSCH is used to transmit downlink data, and it may be determined that, referring to the example of fig. 2, the time interval between DCI and PDCCH is 1 time unit, and then K0 may be 1 time unit, as shown in K0 in fig. 2.

And, in 5G NR, K1 is used to identify the time interval between PDSCH and ACK/NACK, it can be determined with reference to the example of fig. 2 that the time interval between PDSCH and ACK/NACK is 3 time units, and then K1 can be 3 time units, as shown by K1 in fig. 2.

In a possible implementation manner, the units of K0 and K1 may be slots (slots), and in an actual implementation process, the specific settings of K0 and K1 may be configured by the network device according to actual requirements, and the specific settings of K0 and K1 are not limited in this embodiment.

The following briefly introduces related background art for power control:

the DCI includes multiple formats (formats), and DCI information with different formats may be used for different purposes, for example, DCI allocated for downlink RB resources, DCI allocated for uplink RB resources, DCI adjusted for uplink power control, and DCI for downlink dual-stream space division multiplexing, where a protocol classifies DCIs with different uses and distinguishes the DCIs with different DCI formats.

In one possible implementation, the DCI of DCI format 0_1 is used for information such as Uplink PUSCH scheduling of a cell, where the DCI of format 0_1 may include, for example, a carrier indication, an Uplink (UL)/Supplemental Uplink (SUL) indication, and the like.

In a possible implementation manner, 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 configuration Grant Downlink Feedback Information (CG-DFI).

Wherein, the field "DFI flag" may be 1bit (bit), and when the field "DFI flag" is set to 1, it may indicate that the current DCI is used to carry a CG-DFI, and bits after the CG-DFI in the DCI may be set as follows, where the following is attached to an english protocol original text:

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

(HARQ-ACK bitmap–16bits,where the order of the bitmap to HARQ process index 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,value 1indicates ACK,and value 0indicates NACK.)

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

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

All remaining bits of format 0_1 are set to zero.

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

In DCI format 0_1, the TPC command is 2bits, and may be used to indicate a power adjustment amount, so as to indicate how much the power is increased, or may indicate how much the power is decreased, or may also indicate that the power is not changed.

Currently, the TPC command may be carried in DCI, and the power control may be divided into open-loop power control and closed-loop power control, where the open-loop power control refers to performing power control according to its own measurement without requiring feedback information of a receiving end, and the closed-loop power control refers to controlling transmission power by a transmitting end according to feedback information sent by the receiving end.

For the uplink, the closed-loop Power control of the uplink refers to that the network device determines a TPC command according to a measurement result of channel quality of an SRS and a Demodulation Reference Signal (DMRS) reported by the terminal device, a Power Headroom Report (PHR) reported by the terminal device, and other related statistics, and sends the TPC command to the terminal device, and then the terminal device adjusts Power according to the received TPC command.

The open-loop power control of the uplink refers to that the terminal device determines the size of the transmission power by itself without the input of the network device.

Currently, a Physical Random Access Channel (PRACH) in an uplink may employ open loop power control, and closed loop power control may be employed in addition to the PRACH.

On the basis of the related background art described above, the following describes the implementation of the prior art and the problems of the prior art to which the present application relates:

first, a problem of Out of Order execution (OoO) of HARQ-ACK feedback of different priority data in the prior art is introduced with reference to fig. 3, and fig. 3 is a schematic diagram of implementation of triggering HARQ-ACK feedback by a PDSCH provided by the present application.

Referring to fig. 3, fig. 3 includes two COTs (consecutive occupied times) and, within the first COT, includes two PDSCHs, which are PDSCH1 and PDSCH2, respectively.

Wherein PDSCH1 is triggered by PDCCH1, PDSCH1 belongs to group 1, HARQ-ACK feedback time of PDSCH1 is Non-Numerical value K1(Non-Numerical K1, NNK), and its feedback priority is low priority.

Wherein PDSCH2 is triggered by PDCCH2, PDSCH2 belongs to group 1, HARQ-ACK feedback time of PDSCH2 is Non-Numerical value K1(Non-Numerical K1, NNK), and its feedback priority is high priority.

Based on the above, it can be stated that K1 is a non-numeric value, and the specific value of K1 is determined by the next numeric value of K1.

Within the second COT, two PDSCHs are included, PDSCH3 and PDSCH4 respectively.

Wherein PDSCH3 is triggered by PDCCH3, PDSCH3 belongs to group 2, HARQ-ACK feedback time of PDSCH3 is value K1, and its feedback priority is low priority.

Wherein PDSCH4 is triggered by PDCCH4, PDSCH4 belongs to group 2, HARQ-ACK feedback time of PDSCH4 is value K1, and its feedback priority is high priority.

Here, because the priorities of PDSCH3 and PDSCH1 are both low priorities, and K1 of PDSCH3 is numeric, while the priority of PDSCH1 is non-numeric, PDSCH3 may trigger feedback of HARQ-ACKs of PDSCH1 and PDSCH3 together, i.e., feedback of HARQ-ACKs of both together through PUCCH1 in fig. 3.

And, because the priorities of PDSCH4 and PDSCH2 are both high priorities, and K1 of PDSCH4 is numeric while the priority of PDSCH2 is non-numeric, PDSCH4 may trigger feedback of HARQ-ACKs of PDSCH2 and PDSCH4 together, i.e., both through PUCCH2 in fig. 3.

However, in a possible implementation, if there is no PDSCH3 scheduling, that is, there is no low priority PDSCH scheduling, there is no low priority HARQ-ACK, which results in PUCCH1 not being transmitted, but PUCCH2 being transmitted, so that PUCCH2 of high priority HARQ-ACK is fed back earlier than PUCCH1 of low priority HARQ-ACK, because the transmission time of low priority PDSCH1 is earlier and the transmission time of high priority PDSCH2 is later, so the above-described HARQ-ACK feedback situation is not allowed, that is, there is a problem of disorder of HARQ-ACK feedback of different priority data in the prior art.

Another problem with the prior art is that only one TPC information can be indicated in the CG-DFI, since only one grant scheduling PUSCH was previously supported in the non-grant, there is no need to specifically indicate for which PUSCH power control this TPC signaling is used.

But now the configuration of the multiple grant scheduling PUSCH can be supported, so that when the HARQ-ACK of the multiple grant scheduling PUSCH is fed back in the CG-DFI at this time, it cannot be clearly indicated how the power control of the multiple grant scheduling PUSCH is performed.

In view of the above-mentioned problems, the present application provides an information processing method to effectively solve the OoO problem of HARQ-ACK feedback of data with different priorities, and can clarify the implementation manner of power control of PUSCH scheduled by multiple grants, and the method provided by the present application is described below with reference to specific embodiments.

First, an implementation manner for solving the problem of disorder of HARQ-ACK feedback of different priorities in the present application is introduced with reference to fig. 4, fig. 4 is a flowchart of an information processing method provided in an embodiment of the present application, and fig. 5 is an implementation schematic diagram of DCI triggering HARQ-ACK feedback provided in the present application.

As shown in fig. 4, the method includes:

s401, 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 identification.

In the communication process between the terminal device and the network device, the terminal device generally needs to receive DCI transmitted by the network device in order to receive the PDSCH or transmit the PUSCH, where the DCI may indicate all information required by the terminal device to receive the PDSCH or transmit the PUSCH.

In this embodiment, to avoid the problem of disorder in the HARQ-ACK feedback process, the DCI in this embodiment may include the first priority and the first group identifier, so as to trigger the feedback of the HARQ-ACK for the scheduled PDSCH corresponding to the first priority and the first group identifier.

The first group identifier is used for indicating a PDSCH group corresponding to the scheduled PDSCH, and the first priority is used for indicating the priority of the scheduled PDSCH.

Here, the PDSCH group is explained, and in LTE, the PDSCH is currently divided into group 0(Type0) and group 1(Type 1).

Group 0 is allocated in groups and the bitmap sent to the UE indicates which group is used, where the size of a group is related to the number of Resource Blocks (RBs).

Group 1 is a scheme that defines the system bandwidth into several subsets, and indicates the target subset when allocated to a UE, and then indicates that a certain RB or RBs within the target subset are available for use.

In one possible implementation, the first group identifier may be 0 to indicate that the PDSCH group corresponding to the scheduled PDSCH is group 0; alternatively, the first group identifier may be 1 to indicate that the PDSCH group to which the scheduled PDSCH corresponds is group 1.

Alternatively, the first group identifier may also be indication information that has a mapping relationship with group 0 and group 1, for example, may be in a binary implementation form, or may also be a corresponding mapping letter, and the like, which is not limited in this embodiment.

In addition, if there are more PDSCH groups in LTE, for example, there are further group 2, group 3 …, etc., the first group identifier correspondence may be 2, 3 …, etc., which is not limited in this embodiment.

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 also be different degrees of priority such as first priority/second priority/third priority, which depends on the implementation form of the priority, and this is not limited here.

S402, according to the DCI, sending hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback of the PDSCH corresponding to the first priority and the first group identifier to the network equipment.

In this embodiment, in order to avoid the above-described problem of disorder 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 indication of the DCI.

In a possible implementation manner, the DCI sent by the network device may further include Frequency domain resource allocation information, where a field of the Frequency domain resource allocation information in the DCI may be, for example, Frequency domain resource allocation.

The frequency domain resource allocation information may be set to a preset value, so as to trigger HARQ-ACK feedback of the PDSCH corresponding to the first priority and the first group identifier.

In a possible implementation manner, the preset value of the frequency domain resource allocation information may be, for example, all 0 s, or the frequency domain resource allocation information may be, for example, all 1 s, or the frequency domain resource allocation information may also be a preset combination of 0 s and 1 s, and the like.

Or, in another possible implementation manner, 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.

Taking the frequency domain resource allocation information as a preset value as an example, the implementation process of triggering HARQ-ACK feedback is understood with reference to fig. 5, referring to fig. 5, where fig. 5 includes two COTs (continuous occupied time), and in the first COT, includes two PDSCHs, which are PDSCH1 and PDSCH2 respectively.

Within the second COT, one PDSCH, specifically PDSCH3, is included.

Wherein PDSCH3 is triggered by PDCCH3, PDSCH3 belongs to group 2, HARQ-ACK feedback time of PDSCH3 is value K1, and its feedback priority is high priority.

Since the priorities of PDSCH3 and PDSCH2 are both high priorities, and K1 of PDSCH3 is numeric while the priority of PDSCH2 is non-numeric, PDSCH3 may trigger feedback of HARQ-ACKs of PDSCH2 and PDSCH3 together, i.e., both over PUCCH2 in fig. 5.

At this time, in order to avoid that the HARQ-ACK of the PDSCH2 with high priority is earlier than the HARQ-ACK feedback of the PDSCH1 with low priority, the network device may transmit DCI to the terminal device, where the first priority in the DCI may be low priority, and the first group identifier may be group 1.

In this implementation, the DCI has no data scheduling, but sets the frequency domain resource allocation information as a preset value to trigger the terminal device to perform HARQ-ACK feedback of the PDSCH1 corresponding to the low priority and the group 1, so that it is ensured that the PUCCH1 of the low priority HARQ-ACK is fed back earlier than the PUCCH2 of the high priority HARQ-ACK even though there is no PDSCH scheduling of the low priority currently, so as to effectively solve the problem of disorder of HARQ-ACK feedback of data with different priorities.

In a possible implementation manner, for example, a first time duration may be configured in the DCI, where the first time duration is, for example, K1, where the first time duration is used to indicate that the HARQ-ACK of the PDSCH1 is fed back before the HARQ-ACK of the PDSCH2, and a setting manner of the specific first time duration may be selected according to actual requirements as long as the sequential feedback of the HARQ-ACK can be implemented.

It should be noted that, in an actual implementation process, a time for the network device to send the DCI may be selected according to actual requirements, in an example in fig. 5, the time for sending the DCI is after PDSCH3, and it may also be before PDSCH3, for example, which is not limited in this embodiment, as long as the DCI may trigger corresponding HARQ-ACK feedback to ensure HARQ-ACK order feedback of data with different priorities.

It can be understood that, in an actual implementation process, relevant information for indicating HARQ-ACKA feedback, such as K1, NFI, and the like described above, may also be included in the DCI, so that all the relevant information for indicating HARQ-ACKA feedback may be information included in the DCI in this embodiment, and the specific implementation manner of the DCI is not particularly limited in this embodiment.

Meanwhile, the first group identifier and the first priority included in the DCI are determined by the PDSCH that the network device triggers HARQ-ACK feedback through DCI according to current needs, and may be, for example, the PDSCH1 described above, and there is no corresponding PDSCH scheduling of the first priority to trigger HARQ-ACK feedback, so that DCI in this embodiment is needed to trigger, or may also be a PDSCH that the network device determines needs to trigger feedback through DCI according to special needs.

In another possible implementation manner, if the network device determines that the data of the PDSCH does not need to be subjected to the special HARQ-ACK triggering provided in this embodiment currently, for example, the PDSCH corresponding to the first priority and the first group identifier may be subjected to HARQ-ACK feedback sequentially, it may be determined that the frequency domain resource allocation information is not a preset value, so as to perform normal HARQ-ACK triggering.

The information processing method provided by the embodiment of the application comprises the following steps: receiving Downlink Control Information (DCI) sent by network equipment, wherein the DCI comprises at least one of the following information: a first priority and a first group identification. And sending 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 the network equipment according to the DCI. The DCI is triggered to perform data-free scheduling through the DCI indication, and HARQ-ACK feedback of the PDSCH corresponding to the first priority and the first group identifier is triggered, so that the HARQ-ACK feedback of the PDSCH with the first priority can be realized effectively under the condition that the PDSCH scheduling of the numerical value K1 of the first priority does not exist, and the HARQ-ACK sequence feedback of data with different priorities is guaranteed.

On the basis of the foregoing embodiment, a possible implementation manner of the preset value of the frequency domain resource allocation information in the present application is described below, where in this embodiment, the frequency domain resource allocation information includes at least one bit:

if the DCI format only supports the resource allocation of type0 (i.e., indicates available PRBs in a bitmap manner), the frequency domain resource allocation information is preset values: all bits of the frequency domain resource allocation information are 0, that is, the frequency domain resource allocation information is set to 0.

If the DCI format only supports type1 resource allocation (i.e., indicates available PRBs by indicating the starting location and length of the resource), the frequency domain resource allocation information is preset as follows: all bits of the frequency domain resource allocation information are 1, that is, the frequency domain resource allocation information is set to be 1.

If the DCI format supports both the above-described type0 resource allocation and type1 resource allocation, the frequency domain resource allocation information is preset values: 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 s or all 0 s.

In addition, if the control information supports One-time HARQ-ACK feedback (type 3HARQ-ACK codebook), a first field may be set to 0, wherein the first field is a One-time HARQ-ACK requirement field (One-shot HARQ-ACK request).

The information processing method provided by the embodiment of the application can effectively solve the problem of disorder of HARQ-ACK with different priorities.

Meanwhile, the information processing method provided by the present application may also effectively instruct power control, and the following describes an implementation manner of power control with reference to fig. 6, where fig. 6 is a flowchart of an information processing method provided by another embodiment of the present application.

As shown in fig. 6, the method includes:

s601, receiving downlink control information DCI sent by a network device, where if a first field in the DCI for indicating downlink feedback information DFI is preset data, the DCI further includes indication information, and the indication information is used to indicate transmission power control TPC and/or a closed loop corresponding to the TPC.

In this embodiment, if configuration information (configurable granted grant) of a certain configuration granted PUSCH includes information of a powercontrolloopuse (power control loop to be used), it may be determined which loop (loop) corresponds to a current configuration granted PUSCH, and in one possible implementation manner, there may be two loops, or in a possible implementation manner, there may also be more than two loops, and the implementation manner may be adaptively extended with reference to the implementation manner of the two loops.

In this embodiment, if a first field in the DCI for indicating the downlink feedback information DFI is preset data, the DCI of this embodiment further includes indication information, where the indication information is used to indicate a closed loop corresponding to the transmission power control TPC and/or the TPC.

For example, the first field may be the DFI flag described in the above embodiment, and the first field as the preset data may be: DFI flag is 1, indicating that the current DCI is used to carry CG-DFI.

In this embodiment, in order to explicitly indicate how the TPC command implements power control on the multiple configuration grant PDSCHs, the DCI in this embodiment may further include indication information in addition to an existing field, where the indication information is used to indicate the TPC and/or indicate a closed loop to which the TPC corresponds.

In one possible implementation, the indication information is used to indicate an index of the closed loop, and the indication information is 1 bit.

For example, the indication information may be Closed loop index information (Closed loop indicator), because there are two loops, the Closed loop index information may be 1bit, so that which loop corresponds to the TPC command may be effectively indicated, and the configuration information of the PUSCH includes information of powerControlLoopToUse, so that power control indicating the corresponding PUSCH may be effectively implemented.

The closed-loop index information and the TPC command may be as follows:

Closed loop indicator–1bit.

TPC command–2bits

Closed loop indicator–1bit.

TPC command–2bits

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

In another possible implementation manner, the TPC commands of all the closed-loop indication index information may be arranged in an order of the closed-loop indication indexes, for example, the indication information includes at least two sub-indication information, where each sub-indication information is used for indicating the TPC of a corresponding closed loop.

For example, two closed loops currently exist, the indication information may include, for example, first sub-indication information and second sub-indication information, the first sub-indication information being used for indicating the TPC for the first closed loop, and the second sub-indication information being used for indicating the TPC for the second closed loop. Wherein, the first sub-indication information and the second sub-indication information are both 2 bits.

It can be understood that, assuming that two loops coexist, which are respectively denoted by loop0 and loop1, the TPC of the first closed loop0 may be indicated by the first sub-indication information, the TPC of the second closed loop2 may be indicated by the second sub-indication information, and the original TPC is 2bits, so that the first indication information and the second indication information are also 2bits, which may be implemented, for example, as follows:

TPC command for Closed loop indicator 0–2bits

TPC command for Closed loop indicator 1–2bits

the TPC command for Closed loop indicator 0 is a TPC command for the first Closed loop0, and the TPC command for Closed loop indicator 1 is a TPC command for the second Closed loop1, and the indication method is the same as the above-described TPC command, but the difference is that the TPC corresponding to each Closed loop is indicated by decibels, so that the power control indicating the corresponding PUSCH can be effectively realized.

Or, when there are more than two closed loops, the indication information correspondingly includes more than two sub-indication information, and the implementation manner is similar to that of the two closed loops described above, as long as corresponding expansion is performed.

And S602, adjusting the transmitting power according to the indication information.

The indication information in this embodiment may indicate the TPC corresponding to each closed loop, and then the transmit power of the channel corresponding to the closed loop may be adjusted according to the indication information, for example, the transmit power may be indicated to be increased, or the transmit power may be indicated to be decreased, or the transmit power may also be indicated to be unchanged, where the specific power adjustment depends on the indication of the TPC, which is not limited in this embodiment.

The information processing method provided by the embodiment of the application comprises the following steps: receiving Downlink Control Information (DCI) sent by network equipment, wherein if a first field used for indicating Downlink Feedback Information (DFI) in the DCI is preset data, the DCI also comprises indication information, and the indication information is used for indicating a closed loop corresponding to Transmission Power Control (TPC) and/or TPC. And adjusting the transmitting power according to the indication information. The indication information in the DCI indicates the TPC and/or a closed loop corresponding to the TPC, so that the power control of each PUSCH can be effectively realized under the condition of supporting the configuration of a plurality of authorized scheduling PUSCHs.
