Description

Configuration method and device of uplink control channel

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for configuring an uplink control channel.

Background

Semi-persistent scheduling SPS (Semi-Persistent Scheduling, or Semi-persistent scheduling) allows resources of a PDSCH or PUSCH to be periodically allocated to a specific UE through one physical downlink control channel PDCCH scheduling, unlike when the network device transmits the physical downlink control information to the terminal device UE once every scheduling of the physical downlink shared channel PDSCH or the physical uplink shared channel PUSCH during dynamic scheduling. In this procedure, the base station uses the CS-RNTI-scrambled PDCCH to specify radio resources (which will be referred to herein as SPS resources) used by the UE, which the UE uses to receive or transmit data every one period. The base station does not need to issue PDCCH to assign the allocated resources, namely SPS scheduling has the characteristics of one-time allocation and multiple use. In addition, SPS scheduling can avoid the base station from sending scheduling information corresponding to PDSCH to the UE when downlink data is required, can reduce the time delay of downlink data transmission, and can meet the requirement of time delay sensitive service transmission.

The SPS scheduled data supports HARQ transmission, and for each PDSCH transmission according to SPS scheduling, the UE transmits acknowledgement ACK or non-acknowledgement NACK information corresponding to each PDSCH on PUCCH resources corresponding to the PDSCH. The ACK and NACK information are collectively referred to as hybrid automatic repeat request acknowledgement information HARQ-ACK. The entirety of HARQ-ACK information fed back by the UE on one HARQ feedback resource (PUCCH or PUSCH) is referred to as a HARQ-ACK codebook.

The timing relationship between PDSCH and PUCCH is as follows: if the UE receives the PDSCH related to SPS scheduling in the time slot n, the UE feeds back the HARQ-ACK corresponding to the PDSCH in the time slot n+k. The value of k is determined by a "PDSCH-to-HARQ-timing-indicator" field in the PDCCH, or by higher layer signaling "dl-DataToUL-ACK". If the value of k is determined by "PDSCH-to-HARQ-timing-indicator" in the PDCCH, the field indicates that the value of k is one of a plurality of values configured by "dl-DataToUL-ACK". Taking k=4 as an example, when the period of SPS configuration is 2ms, after acquiring PDCCH activating SPS, UE receives PDSCH configured by SPS in time slots n, n+2, n+4, n+6, … …, and sends acknowledgement ACK or non-acknowledgement NACK information of each PDSCH configured by feedback SPS in time slots n+4, n+6, … … according to decoding result.

In the NR TDD system, the frame format configuration is very flexible, and if a slot in which a PUCCH for feeding back HARQ-ACK of the SPS PDSCH is located is configured as a downlink slot, or a symbol of a PUCCH resource for feeding back HARQ-ACK of the SPS PDSCH is configured as a downlink symbol or a flexible symbol, the PUCCH will be cancelled. Accordingly, the network device can only execute retransmission scheduling on the corresponding SPS PDSCH under the condition that HARQ-ACK information is not acquired. In case the terminal device has actually correctly acquired PDSCH of the SPS, the system efficiency is low.

The above problem is particularly serious in the case where the period of SPS configuration is short.

Detailed Description

For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

Fig. 1 is a schematic diagram illustrating that HARQ-ACK feedback corresponding to SPS configured PDSCH in a TDD system is cancelled.

Taking the configuration period of SPS as 1 slot as an example, as shown in fig. 1, k=3. If the slot is configured as "DDDUU", the HARQ-ACK of SPS PDSCH transmitted by slot n, slot n+1, slot n+2 are respectively in slot n+3, slot n+4, and slot n+5. Since slot n+5 is configured as a downlink slot, the HARQ-ACK of SPS PDSCH transmitted by slot n+2 will be forced to cancel, affecting system efficiency.

Fig. 2 is a modification of HARQ-ACK feedback timing corresponding to SPS configured PDSCH in a TDD system.

For the problem that the HARQ-ACK feedback corresponding to the SPS configuration PDSCH in the TDD system is cancelled, and the system efficiency is affected, one possible solution is to delay the cancelled HARQ-ACK feedback to be transmitted on the next PUCCH. As shown in fig. 2, HARQ-ACK delay for SPS PDSCH of slot n+2 is transmitted on PUCCH of slot n+8.

In the prior art, the configuration information used by all slots is the same whether the PUCCH resources for HARQ-ACK information feedback configured to SPS, PUCCH resources for channel state information feedback, or PUCCH resources for HARQ-ACK information feedback configured to dynamically scheduled PDSCH. Therefore, the maximum capacity of each type of PUCCH is the same in all slots on the basis of ensuring a specific transmission performance.

However, the delayed transmission of HARQ-ACKs corresponding to SPS configured PDSCH in TDD systems may cause great differences in HARQ-ACK feedback requirements for different time slots. For example, slot n+8 shown in fig. 2 needs to carry a delayed HARQ-ACK while slot n+9 does not need to carry a delayed HARQ-ACK. The configuration resource of the PUCCH can ensure the transmission performance of the control information without delaying the HARQ-ACK, but when the PUCCH is used to carry the delayed HARQ-ACK, the performance of the delayed HARQ-ACK cannot be ensured, and the performance of the uplink control information originally carried by the PUCCH is affected.

For example, if the bearer delay HARQ-ACK is not considered or the number of delay HARQ-ACKs is small, the network device configures two PUCCH resources to the UE through AN SPS-PUCCH-AN-List-r16 message (or a multi-CSI-PUCCH-resource List message, a resource esttolelease message) in the higher layer signaling PUCCH-Config configuration information: PUCCH-a and PUCCH-B. PUCCH-A resources are used for bearing 1-X ₁ Bit information, PUCCH-B for bearer (X ₁ +1)～X ₂ Bit information. However, the UE needs to carry a large amount of delayed HARQ-ACKs of the burst, and UCI information needed to be carried may reach X ₃ Bits, where X ₃ ＞＞X ₂ . At this time, the PUCCH-B cannot directly carry X ₃ Bit information, if a large number of delayed HARQ-ACKs are carried, the coding rate must be increased or a part of the information must be discarded, resulting in a significant decrease in the reliability of the PUCCH. On the other hand, if the configured PUCCH-B capacity is suitable for the bearer (X ₁ +1)～X ₃ The bit information inevitably causes resource waste in a time slot in which the delay of the HARQ-ACK does not occur or occurs less, the multiplexing capability of the uplink resource of the system is deteriorated, and the efficiency is reduced.

Referring to 3gpp TS 38.213 V16.3.0 and 3gpp TS 38.331 V16.3.0, PUCCH resources for transmitting HARQ-ACK information for downlink SPS are configured using SPS-PUCCH-AN-List-r16 message in configuration information PUCCH-Config. If the bearing delay HARQ-ACK is not considered, the maximum capacity PUCCH in the PUCCH configuration has the number of resource blocks of

Information that may cause actual transmission when delayed HARQ-ACK occurs exceeds + ->

The number of uplink control information bits which can be carried by each resource block according to the set coding rate can only be carried by a mode of improving the coding rate, thus affecting the performance of HARQ-ACK and further affecting the downlink efficiency of the system. On the contrary, the method comprises the steps of,if the maximum demand of the bearing delay HARQ-ACK is considered, the configured PUCCH resource capacity is larger than the actual demand in the time slot with no or less occurrence of the delay HARQ-ACK, and the multiplexing efficiency of the uplink resource of the system is affected.

For another example, PUCCH resources for transmitting channel state information are configured using a multi-CSI-PUCCH-resource list message in the configuration information PUCCH-Config. If the bearing delay HARQ-ACK is not considered, the maximum capacity PUCCH in the PUCCH configuration has the number of resource blocks of

The number of uplink control information bits which can be carried by the resource blocks according to the set coding rate, and partial CSI on the PUCCH are discarded, so that the uplink control information carried on the PUCCH does not exceed +.>

The number of uplink control information bits that can be carried by each resource block according to the set coding rate. Discarding CSI will affect the performance of CSI feedback, further affecting the downlink efficiency of the system. Otherwise, if the maximum requirement of carrying delayed HARQ-ACK is considered, the configured PUCCH resource capacity is larger than the actual requirement in the time slot in which the delayed HARQ-ACK does not occur or occurs less, and the multiplexing efficiency of the uplink resource of the system is affected.

For another example, HARQ-ACKs for transmitting dynamically scheduled PDSCH are configured using a resourcesettetreleaselist message in the configuration information PUCCH-Config. If the bearing delay HARQ-ACK is not considered, the PUCCH resources in the PUCCH resource group with the largest capacity in the PUCCH configuration have the number of resource blocks of

The uplink control information bit number that can be carried by each resource block according to the set coding rate, the CSI with lower priority on these PUCCH resource groups will be discarded, affecting the performance of CSI feedback, and further affecting the downlink efficiency of the system. If the uplink control information is still above +. >

The number of uplink control information bits that can be carried by each resource block according to the set coding rate is required to be carried by increasing the coding rate. Otherwise, if the maximum requirement of carrying delayed HARQ-ACK is considered, the capacity of the configured PUCCH resource group is larger than the actual requirement in the time slot in which the delayed HARQ-ACK does not occur or occurs less, and the multiplexing efficiency of the uplink resource of the system is affected.

The invention solves the problem of how the network equipment configures PUCCH resources under the condition of HARQ-ACK delay transmission of SPS PDSCH so as to meet UCI feedback requirements at different moments and solve the problem of low system efficiency.

the application provides a configuration method of an uplink control channel, which comprises the following steps:

step 101, configuring at least 2 PUCCH sets, wherein each PUCCH set contains at least one PUCCH or PUCCH resource group; the first PUCCH is the largest capacity PUCCH or PUCCH resource group in the first PUCCH set, and the second PUCCH is the largest capacity PUCCH or PUCCH resource group in the second PUCCH set, and the capacity of the second PUCCH is larger than the capacity of the first PUCCH.

The number of "at least one" herein is 1 or more, and a specific number of embodiments are described in step 103B.

At least one of the following is different between the first PUCCH and the second PUCCH: the number of included resource blocks, the number of symbols, the modulation order, and the maximum coding rate.

Step 102, determining that HARQ-ACK feedback of PDSCH of SPS configuration is cancelled due to configuration collision.

The configuration collision means that a slot in which a PUCCH for feeding back HARQ-ACK of SPS PDSCH is located is configured as a downlink slot, or a symbol of a PUCCH resource for feeding back HARQ-ACK of SPS PDSCH is configured as a downlink symbol or a flexible symbol. In particular, the configuration conflict includes that a preset PUCCH resource for feeding back HARQ-ACK conflicts with a flexible symbol or a downlink symbol in TDD configuration.

The timing relationship between the PDSCH of SPS and the corresponding HARQ-ACK feedback is determined by the "PDSCH-to-HARQ-timing-indicator" field in the PDCCH that activates SPS, or by higher layer signaling "dl-DataToUL-ACK". For one active SPS configuration, the feedback time difference between each SPS PDSCH and its corresponding HARQ-ACK is "k". In the TDD system, if a slot in which a PUCCH for feeding back HARQ-ACK of SPS PDSCH is located is configured as a downlink slot, or at least one symbol of a PUCCH resource for feeding back HARQ-ACK of SPS PDSCH is configured as a downlink symbol or a flexible symbol, the PUCCH will be cancelled. And the network equipment can only execute retransmission scheduling on the PDSCH of the SPS corresponding to the network equipment under the condition that the HARQ-ACK information is not acquired. In case the terminal device has actually correctly acquired PDSCH of the SPS, the system efficiency is low. The above problem is particularly serious in the case where the period of SPS configuration is short.

Therefore, when the preset PUCCH resources corresponding to the HARQ-ACKs of the SPS-configured PDSCH are cancelled due to collision with the flexible symbols or downlink symbols in the TDD configuration, the HARQ-ACKs of the SPS-configured PDSCH will be transmitted in other PUCCH delays, and in this application, these delayed transmitted HARQ-ACKs are referred to as "delayed HARQ-ACKs".

Step 103, in the target time unit, determining a target PUCCH or a target PUCCH resource group in the first PUCCH set or the second PUCCH set according to the number of delayed HARQ-ACKs supported in UCI and a preset value size.

The target time unit here, for example, a subsequent symbol or slot including PUCCH discarded due to configuration collision, is a time unit in which the target PUCCH for transmitting the delayed HARQ-ACK is located.

For example, the PUCCH transmitting the delayed HARQ-ACK is a PUCCH resource configured for HARQ-ACK information feedback of SPS. Some uplink timeslots need to carry HARQ-ACKs for SPS PDSCH transmitted with delay, e.g., slot n+8, while some uplink timeslots do not need to carry HARQ-ACKs for SPS PDSCH transmitted with delay, e.g., slot n+9. Further, for different TDD configurations, there are more HARQ-ACKs for the SPS PDSCH that needs to be carried with delay in some uplink timeslots, and there are fewer HARQ-ACKs for the SPS PDSCH that needs to be carried with delay in some uplink timeslots. This means that the demands of different slots on the PUCCH resources with the largest capacity are different, so that the corresponding PUCCH sets in determining the target PUCCH may be different in slots with different numbers of supported delayed HARQ-ACKs.

Step 103A, selecting a group of PUCCH configurations in an uplink slot in which HARQ-ACK is transmitted.

In the subsequent uplink time slot, when the number of the delayed HARQ-ACKs supported in the UCI is not greater than a preset value, determining a target PUCCH in the first PUCCH set, and when the number of the delayed HARQ-ACKs supported in the UCI is greater than the preset value, determining a target PUCCH in the second PUCCH set.

The PUCCH resources configured for HARQ-ACK information feedback for SPS in the prior art are the same for all slots, which means that the maximum capacity of PUCCH is the same for all slots on the basis of guaranteeing specific transmission performance. If there are uplink timeslots that need to carry more HARQ-ACKs for the SPS PDSCH that is transmitted with delay, there are uplink timeslots that need to carry fewer HARQ-ACKs for the SPS PDSCH that is transmitted with delay. This means that different slots have different demands for the maximum capacity PUCCH resources. The PUCCH configuration in the prior art may cause that the reliability of the uplink control information may not meet the requirement, or the resource usage efficiency of the system is poor.

In order to solve the problem, the network device base station gNB may determine the maximum capacity of the second PUCCH according to the number of delayed HARQ-ACKs supported by the UE and the maximum capacity of the first PUCCH, and when the number of delayed HARQ-ACKs for carrying is greater than a preset value, use any one of the second PUCCH sets to carry uplink control information. The delayed HARQ-ACK information which can be carried by at least one PUCCH in the second PUCCH set is larger than a preset value, the transmission performance of the delayed HARQ-ACK and other uplink control information in the target PUCCH is not affected, excessive resources are not allocated to the uplink control information, and the system efficiency is not affected.

By using the scheme of the invention, the gNB can configure the first PUCCH set and the second PUCCH set according to the quantity of the delayed HARQ-ACK information supported by the UE, and the gNB is respectively used for determining the target PUCCH under the condition that the quantity of the delayed HARQ-ACK carried by the gNB is not more than a preset value and the quantity of the delayed HARQ-ACK carried by the gNB is more than the preset value.

For example, configured PUCCH-A resources are used to carry 1-X ₁ Bit information, PUCCH-B for bearer (X ₁ +1)～X ₂ Bit information, PUCCH-C, for carrying (X ₁ +1)～X ₃ Bit information. In the time slot that the number of the carried delayed HARQ-ACK is not more than the preset value, the UE considers the PUCCH resources configured for the HARQ-ACK information feedback of the SPS to comprise PUCCH-A and PUCCH-B. The number of delayed HARQ-ACKs on the bearer is largeIn a time slot with a preset value, the UE considers that the PUCCH resources for feeding back the HARQ-ACK information configured to the SPS comprise PUCCH-A and PUCCH-C. At this time, the first PUCCH set includes PUCCH-A and PUCCH-B, and the second PUCCH set includes PUCCH-A and PUCCH-C. The first PUCCH is PUCCH-B, and the second PUCCH is PUCCH-C. Or in the time slot that the number of the carried delayed HARQ-ACKs is larger than the preset value, the UE considers that the PUCCH resources configured for the HARQ-ACK information feedback of the SPS comprise PUCCH-A, PUCCH-B and PUCCH-C, and at the moment, the second PUCCH set comprises PUCCH-A, PUCCH-B and PUCCH-C. The first PUCCH is PUCCH-B, and the second PUCCH is PUCCH-C.

Step 103B, determining a target PUCCH in the selected PUCCH set configuration.

For example, the selected PUCCH set is configured as the first type PUCCH.

The network equipment configures 1-4 PUCCH resources with different capacities to the UE through SPS-PUCCH-AN-List-r16 information in the high-layer signaling PUCCH-Config configuration information, and the capacities are sequentially increased. According to O by UE _UCI One of the 1-4 PUCCH resources is determined as a target PUCCH of a feedback HARQ-ACK codebook, wherein O _UCI Is the total number of bits of the HARQ-ACK codebook (containing delayed HARQ-ACK information) and possibly SRs:

if O _UCI 2, wherein the target PUCCH is 1 st of 4 PUCCH resources;

if 2<O _UCI ≤N _1,SPS The target PUCCH is 2 nd of 4 PUCCH resources, and if the configuration parameter of the second PUCCH includes maximum bit number configuration information, N _1,SPS Is the number of bits of the configuration, otherwise N _1,SPS Equal to 1706;

if N _1,SPS <O _UCI ≤N _2,SPS The target PUCCH is 3 rd, N of 4 PUCCH resources _1,SPS Is the maximum number of bits configured for the 2 nd PUCCH, if the configuration parameter of the 3 rd PUCCH includes the maximum number of bits configuration information, N _2,SPS Is the number of bits of the configuration, otherwise N _2,SPS Equal to 1706;

if N _2,SPS <O _UCI ≤N _3,SPS The target PUCCH is the 4 th, N, of 4 PUCCH resources _2,SPS Is the maximum number of bits configured for the 2 nd PUCCH, N _3,SPS Equal to 1706.

After determining the target PUCCH, if the target PUCCH is format 2 or format 3 of the PUCCH, the target PUCCH resource includes

The number of resource blocks, the resources actually used for transmitting the HARQ-ACK are a plurality of resource blocks starting from the initial resource block of the target PUCCH, and the specific number of the plurality of resource blocks is one of the following:

if it is

The number of resource blocks actually used for transmitting HARQ-ACK and possible SR in the target PUCCH is +.>

And (b) wherein

Is not greater than->

And satisfy the condition->

And->

Is an integer of (a). That is, when the UCI bit number does not exceed the limit, the number of PUCCH resource blocks actually used is determined according to the actual requirement of the HARQ-ACK bit number, and fewer HARQ-ACK bit numbers use fewer resource blocks.

If it is

The number of resource blocks actually used for transmitting HARQ-ACKs and possibly SRs is +.>

And each. I.e. the UCI number of bits exceeds a certain limit, only +.>

Is available. When the UCI bit number is large, the coding rate will be high and the transmission performance is poor.

Wherein O is _ACK Is the number of bits of HARQ-ACK, O _CRC Is the number of cyclic redundancy check bits appended before the coding of the HARQ-ACK information,

Q _m and r are the number of subcarriers included in a resource block of one PUCCH, the number of symbols included in the PUCCH, the modulation order of the PUCCH, and the maximum coding rate of the PUCCH, respectively.

It should be noted that, when the number of delayed HARQ-ACKs of the supported bearers is not greater than the preset value, the number of bits that the first PUCCH set may accommodate UCI is not greater than 1706. When the delayed HARQ-ACK of the supported bearer is large, the number of bits that the second PUCCH can accommodate UCI may be greater than 1706.

For another example, the selected PUCCH set is configured as a second type PUCCH.

The network device configures resources of J.ltoreq.2 PUCCH formats 2, 3 or 4 for the UE through a multi-CSI-PUCCH-resource list message in the high-level signaling PUCCH-Config configuration information. The capacity of the J PUCCHs increases in sequence. The UE determines one of the J PUCCH resources as a target PUCCH for transmitting the channel state information and HARQ-ACK information of the DL SPS, and possibly an uplink scheduling request SR.

Wherein O is _ACK Is the number of bits of HARQ-ACK, O _SR Is the number of bits of SR, O _CSI Is the bit number of CSI, O' _CSI Is the number of bits to select the reported CSI.

Q _m And r are the number of subcarriers included in a resource block of one PUCCH, the number of symbols included in the PUCCH, the modulation order of the PUCCH, and the maximum coding rate, respectively. That is, according to O _ACK +O _SR +O _CSI +O _CRC After determining which PUCCH resource to use as the target PUCCH, all resource blocks of the target PUCCH are actually used for CSI/HARQ-ACK/SR information.

For another example, the selected PUCCH set is configured as a third type PUCCH.

When the HARQ-ACK of the dynamically scheduled PDSCH and the HARQ-ACK of the SPS configured PDSCH are located in the same slot, the HARQ-ACK codebook includes two types of HARQ-ACK information: HARQ-ACKs for DL SPS and HARQ-ACKs for dynamically scheduled PDSCH, where SPS configured PDSCH HARQ-ACKs in turn contain delayed HARQ-ACK information. In addition to the HARQ-ACK codebook, at the feedback time of the PUCCH, the terminal device may need to feed back other uplink control information such as the scheduling request SR and/or channel state information to the network device, where the number of bits of the uplink control information UCI is denoted as O _UCI 。

The network device configures 1-4 PUCCH resource groups for the UE through a resource eSeretToReleaseList message in the PUCCH-Config configuration information.

Fig. 4 is a flowchart of an embodiment of a method of the present application for a network device.

The method according to any one of the embodiments of the first aspect of the present application, for a network device, includes the following steps 201 to 204:

step 201, sending first configuration information and second configuration information; the first configuration information is used for configuring a first PUCCH set; the second configuration information is used for configuring a second PUCCH set;

transmitting the first configuration information and the second configuration information; the first configuration information is used for determining a first PUCCH set, and the number of the delayed HARQ-ACKs used for the supported bearer by the first PUCCH set is not larger than a preset value; the second configuration information is used for determining a second PUCCH set, the number of delayed HARQ-ACKs used for supported bearers is greater than a preset value, the preset value is greater than or equal to zero, the delayed HARQ-ACKs are HARQ-ACK information of SPS PDSCH that is delayed to be sent, and when HARQ-ACK feedback of PDSCH configured by SPS is cancelled due to configuration collision.

In an embodiment, the first configuration information and the second configuration information may be used to configure the first PUCCH and the second PUCCH, respectively. The capacity of the second PUCCH is greater than the capacity of the first PUCCH. The specific configuration information about the first PUCCH and the second PUCCH in the first configuration information and the second configuration information is different in at least one of the number of resource blocks of the PUCCH, the number of symbols included in the PUCCH, the modulation order of the PUCCH, the maximum coding rate of the PUCCH, and the format parameter of the PUCCH. For the configuration items with the same parameters and parameter values in the first configuration information and the second configuration information, the network device may send only once.

With the scheme of the invention, the gNB can configure the first PUCCH and the second PUCCH according to the quantity of the delayed HARQ-ACK information supported by the UE. As in the example above, the first configuration information configures PUCCH-B for the bearer (X ₁ +1)～X ₂ Bit information. The second configuration information configures PUCCH-C for a bearer (X ₁ +1)～X ₃ Bit information. The UE considers that the first PUCCH set resources configured for HARQ-ACK information feedback of the SPS are PUCCH-A and PUCCH-B, and the second PUCCH set resources are PUCCH-A and PUCCH-C.

Alternatively, the first configuration information configures PUCCH-B for a bearer (X ₁ +1)～X ₂ Bit information. Second configuration information configures PUCCH-C for bearer (X ₂ +1)～X ₃ Bits. The UE considers that the first PUCCH set resources configured for HARQ-ACK information feedback of the SPS are PUCCH-A and PUCCH-B, and the second PUCCH set resources are PUCCH-A, PUCCH-B and PUCCH-C.

In this way, in some time slots, the second PUCCH corresponding to the second configuration information may carry delayed HARQ-ACK information greater than a preset value, and the transmission performance of the delayed HARQ-ACK and other uplink control information is not affected; in other time slots, the first PUCCH corresponding to the first configuration information may carry delayed HARQ-ACK information smaller than a preset value, and may not allocate excessive resources for the uplink control information, so as to affect system efficiency.

Step 202, determining a configuration conflict, comparing the number of delayed HARQ-ACKs supported by UCI with a preset value in a target time unit, and determining a target PUCCH (or PUCCH resource group) in a first PUCCH set or a second PUCCH set;

by adopting the scheme of the embodiment, different from the prior art, the transmission performance of uplink control information including delay HARQ-ACK in the PUCCH can be ensured and the system efficiency can be ensured by independently selecting and configuring different time slots according to the quantity of delay HARQ-ACK information supported by the UE and configuring different PUCCH maximum resources for different time slots.

Step 203, receiving the delayed HARQ-ACK in the target PUCCH.

Receiving first type uplink control information at an actual resource of a target PUCCH, wherein the number of delay HARQ-ACK included in the first type uplink control information is not more than a preset value; and receiving second-type uplink control information at the actual resource of the target PUCCH, wherein the delay HARQ-ACK information included in the second-type uplink control information is larger than a preset value.

If it is determined that the first type of uplink control information is received in the target PUCCH, the actual resource on the target PUCCH for transmission of the first type of uplink control information may be part or all of the target PUCCH.

Fig. 5 is a flowchart of an embodiment of a method for a terminal device according to the present application.

The method according to any one of the embodiments of the first aspect of the present application is used for a terminal device, and includes the following steps 301 to 304:

step 301, receiving first configuration information and second configuration information; the first configuration information is used for configuring a first PUCCH set; the second configuration information is used for configuring a second PUCCH set;

the terminal equipment acquires first configuration information and second configuration information; determining a first PUCCH set when the number of the delayed HARQ-ACKs supported by the carrier is not more than a preset value through first configuration information; and determining a second PUCCH set when the number of the delayed HARQ-ACKs of the supported bearer is larger than a preset value through second configuration information.

Step 302, determining configuration conflict, in a target time unit, comparing the number of delayed HARQ-ACKs supported by UCI with a preset value, and determining a target PUCCH in a first PUCCH set or a second PUCCH set;

the terminal equipment determines the number of the delayed HARQ-ACKs supported by the target UCI; when the number of the carried delayed HARQ-ACKs is not greater than a preset value, determining a target PUCCH in a first PUCCH set, further determining actual resources and sending the target UCI; and when the number of the supported delayed HARQ-ACKs is larger than a preset value, determining a target PUCCH in the second PUCCH set, further determining actual resources and sending the target UCI. The UE may determine a target PUCCH at the target PUCCH resource group through scheduling indication information transmitted by the network device.

Step 303, transmitting the delayed HARQ-ACK in the target PUCCH.

As described above, in the related art, the configuration information is the same in all slots regardless of PUCCH resources for HARQ-ACK information feedback configured for PDSCH configured for SPS, PUCCH resources for channel state information feedback, or PUCCH resources for HARQ-ACK information feedback including dynamically scheduled PDSCH. If the number of HARQ-ACKs of the SPS PDSCH that needs to be carried and delayed for transmission in some uplink timeslots is large, and the number of HARQ-ACKs of the SPS PDSCH that needs to be carried and delayed for transmission in some uplink timeslots is small, the PUCCH configuration method in the prior art may cause that the reliability of uplink control information cannot meet the requirement, or the resource utilization efficiency of the system is poor. By adopting the scheme of the embodiment, the gNB determines the maximum capacity of the second PUCCH set according to the quantity of the delayed HARQ-ACK information supported by the UE and the maximum capacity of the first PUCCH set, and when the quantity of the delayed HARQ-ACK for the supported bearer is larger than a preset value, the gNB uses a target PUCCH in the second PUCCH set to bear uplink control information.

It should be noted that, in the embodiment of the present application, the preset value may be greater than or equal to zero. If the preset value is equal to zero, the present embodiment is equivalent to configuring different maximum resources for PUCCHs carrying and not carrying delayed HARQ-ACKs through configuration information of the target PUCCH. If the preset value is greater than zero, the present embodiment configures different resources for the supported PUCCHs carrying different numbers of delayed HARQ-ACKs through the configuration information of the PUCCHs.

When the first PUCCH set and the second PUCCH set in the present application include a plurality of PUCCH resource groups, the first PUCCH may be a first PUCCH resource group, the second PUCCH may be a second PUCCH resource group, and the target PUCCH may be a target PUCCH resource group.
