Description

A method of determining and configuring physical uplink control channel resources, user terminals, network-side equipment, devices and computer program media

The present invention belongs to the field of communication technology, and in particular relates to a method of configuring and determining PUCCH (Physical Uplink Control Channel, physical uplink control channel) resources, user terminals, network side equipment, devices and computer program media.

With the development of mobile video services and peer-to-peer multicast/broadcast streaming services, through software upgrades of mobile networks, group communications and broadcast/multicast LoT (Internet of Things, Internet of Things) applications are increasingly popular, global mobile communications The industry has reached consensus that the future fifth-generation mobile communication 5G network needs to have the ability to flexibly and dynamically allocate wireless spectrum and network resources between unicast services and multicast services, and needs to support broadcast/multicast Independent deployment of the network.

In the current 5G, the data sent by the base station to the terminal includes two types of data: one is terminal-oriented data, which can only be received by the target terminal, and this kind of data becomes unicast data; the other is data oriented within the community. All terminals or specific group data, that is, all users in the community or specific group users can receive the service.

In order to ensure the communication quality of the data, for sending broadcast multicast service data, the UE is required to perform UCI (Uplink Control Information, uplink control information) such as HARQ-ACK (Hybrid Automatic Repeat Request-ACK Nowledgement, Hybrid Automatic Repeat Request Acknowledgment) feedback. The feedback of HARQ-ACK is based on the feedback information of the data reception result. When the data is received correctly, ACK is returned (that is, correct reception confirmation), and when the data is received incorrectly, NACK is returned (that is, data is not received correctly and confirmed).

For existing technologies, the unicast-based HARQ scheduling process is only suitable for one receiving UE to perform HARQ-ACK feedback. However, for broadcast multicast services, a group of UEs or all UEs in the community receive the service. Therefore, the existing unicast HARQ scheduling and feedback indication mechanisms are not suitable for cellular-based broadcast multicast feedback.

For the existing technology, the process of feeding back NACK/ACK in the HARQ scheduling process based on side links requires uplink feedback resources to be allocated to all UEs. There are two problems: First, the receiving UE is in a different position from the base station. To effectively feed back HARQ-ACK, some need to occupy 2 symbols, some need to occupy 4 symbols, and some even need to occupy 14 symbols. However, the uplink feedback resource configuration of the existing solution is a unified format, which cannot meet the needs of cellular feedback. HARQ-ACK requirements; secondly, the current design only supports 1-bit feedback. When broadcast and multicast services need to feedback multi-bit HARQ-ACK feedback information (such as the UE receiving multiple PDSCH (Physical Downlink Shared channel, entity Downlink shared channel) data packet, fed back on a PUCCH), current technology cannot meet the above requirements.

It can be seen that the current scheduling signaling mechanism cannot allow the UE to effectively feedback HARQ-ACK codebook information. For other UCI control information outside the HARQ-ACK codebook, there is also a problem that the current scheduling signaling cannot meet the UE's feedback needs.

In order to help the review committee understand the technical features, content and advantages of the present invention and the effects it can achieve, the present invention is described in detail below in conjunction with the accompanying drawings and in the form of embodiments. The drawings used therein are as follows. The subject matter is only for illustration and auxiliary description, and does not necessarily represent the actual proportions and precise configurations after implementation of the present invention. Therefore, the proportions and configuration relationships of the attached drawings should not be interpreted to limit the scope of rights of the present invention in actual implementation. Let’s explain first.

Currently, the HARQ-ACK (Hybrid Automatic Repeat Request-ACK Nowledgement) feedback mechanism mainly includes HARQ-ACK feedback for unicast services and HARQ-ACK feedback for broadcast multicast services on side links. The details are as follows.

1. HARQ-ACK feedback mechanism based on unicast service

In a wireless communication environment, since the channel quality changes rapidly, data transmission errors may occur. In order to improve the reliability of data transmission, we must meet the different transmission quality requirements of different services. The standard adopts the hybrid automatic retransmission HARQ process, that is, the receiving end decodes the received data and feeds back the decoding result to the sending end. When the decoding result is correct, ACK information is fed back. When the decoding is incorrect, NACK information is fed back. The data sending end determines whether to retransmit the data based on the received decoded feedback information. Generally, when the feedback information received by the data sending end is NACK information, the data is retransmitted. When the feedback information received is ACK information, the data sending end will retransmit the data. , no data retransmission is performed, and this data transmission ends.

The specific HARQ process description is shown in Figure 1. Assume that the initial transmission decoding is incorrect and the secondary transmission decoding is correct. The specific HARQ process is as follows: 1) The sending end gNB sends the data transmission block TB1 (Transport Block, Transport Block) for the first time to The receiving end UE, and instructs the UE to feed back the PUCCH (Physical Uplink Control Channel, physical uplink control channel) time slot and frequency domain resource information of the HARQ-ACK; 2) The receiving end UE decodes TB1, and the decoding result is an error, and feeds back NACK to the sending end on the PUCCH resource of the specified time slot; 3) The sending end gNB receives the NACK information, indicating that the UE did not receive TB1 correctly, then the data The transmission block TB1 is resent (i.e., retransmitted), and instructs the UE to feed back the time slot and frequency domain resource information of the PUCCH of HARQ-ACK; 4) The receiving end UE decodes TB1 again (the UE may compare it with the previous data Merge), the decoding result is correct, and ACK is fed back to the data sending end. The sending end feeds back ACK information to the data sending end on the PUCCH resource of the specified time slot.

After the sending end receives the ACK information, it determines that the UE has correctly received TB1, and the data sending process is completed.

As shown in Figure 2, it is a schematic diagram of the data scheduling and HARQ-ACK feedback channel in the HARQ process. The relevant content is described in detail below.

1) The sending end gNB sends data scheduling information on PDCCH (Physical Downlink Control Channel, physical downlink control channel) in time slot slot n. The scheduling information includes the following content: The time domain and frequency domain position of the data channel: k0 in the figure Indicates the offset time slot number of the data channel relative to the control channel, that is, the distance between the PDSCH and PDCCH time slots. When k=0, it means that it is in the same time slot as PDCCH. When k0=1, it means that PDSCH is in the time slot after the time slot where PDCCH is located. In Figure 2, k0 is assumed to be 2.

Modulation and coding format of data channel: Indicates the modulation order and channel coding rate adopted by PDSCH.

Feedback HARQ-ACK time domain information: Indicates the position of the HARQ-ACK feedback time slot from the PDSCH. When k1=0, it means that the HARQ-ACK feedback time slot is fed back in the same time slot as the PDSCH. In Figure 2, k1=4.

Feed back HARQ-ACK information in the frequency domain resources of the PUCCH in the specified time slot.

2) The receiving end UE detects the PDCCH in time slot slot n, receives the PDSCH data according to the data scheduling information transmitted on the PDCCH, demodulates and decodes the data, and sends the decoding result (if the decoding is correct, feedback ACK, if the decoding is wrong , feedback NACK) is fed back to the base station on the PUCCH frequency domain resource of the designated time slot.

2. HARQ-ACK feedback mechanism of side link broadcast multicast service

Side link is based on end-to-end communication link. For Sidelink broadcast multicast communication, the main solution is based on HARQ ACK/NACK feedback method: In this method, each receiving UE (Rx UE) has its own independent PSFCH (Physical Side Feedback Channel, physical side link feedback channel) resource, each Rx UE determines whether it correctly receives the PSSCH (Physical Side Shared Channel, physical side link shared channel), thereby sending HARQ on the corresponding PSFCH resource ACK/NACK information.

The main application scenario of the above solution is when there are relatively few UEs in the group and only supports 1-bit HARQ-ACK feedback.

It can be seen that when the base station currently sends broadcast multicast data, it sends group-based scheduling messages. When the UE needs to feedback HARQ-ACK, the existing air interface scheduling signaling mechanism cannot allow the UE to effectively feedback HARQ-ACK information. Similarly , In addition to HARQ-ACK, other UCI (Uplink Control Information, uplink control information) also has the problem of being unable to meet the UE feedback needs.

Aiming at the problem that the current air interface scheduling signaling mechanism cannot meet the UE's demand for UCI feedback, embodiments of the present invention provide a solution and propose to configure at least one PUCCH resource unit for One or more groups of UEs perform DCI feedback. The above UCI can be HARQ-ACK, or CSI (Channel State Information, channel state information), or it can be HARQ-ACK and CSI, or other information reported to the network side device. information. Correspondingly, the number of bits when performing DCI feedback may correspond to the number of HARQ-ACK bits of the terminal, the number of corresponding CSI bits, or the number of HARQ-ACK bits plus the number of CSI bits.

Example 1.

In view of this, embodiments of the present invention provide a system for configuring and determining PUCCH resources, which can meet different PUCCH resource occupation requirements and effectively solve the UCI feedback problem of UE in a broadcast multicast scenario. As shown in Figure 3, embodiments of the present invention provide configuration The system for determining PUCCH resources includes a user terminal 301 and a network side device 302.

In the embodiment of the present invention, the user terminal UE may specifically refer to an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication Device, user agent, or user device. The access terminal may be a cellular phone, a wireless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a wireless Handheld devices with communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, and mobile stations in 5G networks or future evolved Public Land Mobile Network (PLMN) networks Subscription devices on the road, etc.

The network side equipment can be a next-generation base station (generation Node B, gNB) in the 5G system, which can be a Global System of Mobile communication (GSM) system or a Code Division Multiple Access (CDMA) system. Base station (Base Transceiver Station, BTS), or the base station (NodeB, NB) in the Wideband Code Division Multiple Access (WCDMA) system, or the evolution in the Long Term Evolution (LTE) system Type base station (Evolutional Node B, eNB or eNodeB), etc.

The communication spectrum between terminals and network equipment can be licensed spectrum, unlicensed spectrum, or visible light.

When the feedback link is a side link, the network device can be a terminal or a roadside unit.

It should be noted that the above system architecture is only an example of the system architecture applicable to the embodiment of the present invention. Compared with the system architecture shown in Figure 3, the system architecture applicable to the embodiment of the present invention may also add other entities or reduce some entities.

In the above system, the user terminal 301 is used to obtain the configuration information of at least one PUCCH resource unit group, where a PUCCH resource unit group includes at least one PUCCH resource and is used for UCI feedback by UEs in a broadcast multicast service group; the receiving network The broadcast multicast configuration information sent by the road side and the group number of the UE in the corresponding PUCCH resource unit group; channel detection is performed based on the broadcast multicast configuration information, the scheduling signaling is obtained, and the broadcast multicast data is received according to the scheduling signaling and Determine the UCI that needs to be fed back; determine the PUCCH resources occupied by the UCI that are fed back according to the configuration information of the PUCCH resource unit group corresponding to the UE, the group number, and the UCI that needs to be fed back.

In the above system, the network side device 302 is used to configure at least one PUCCH resource unit group, where one PUCCH resource unit group includes at least one PUCCH resource, which is used for UCI feedback by UEs in a broadcast multicast service group; sends the broadcast group to the UE broadcast configuration information and the group number of the UE in the corresponding PUCCH resource unit group; send scheduling signaling for channel detection to the UE, And send broadcast multicast data; after receiving the UE to determine the PUCCH resource according to the configuration information of the corresponding PUCCH resource unit group, the group number and the UCI to be fed back, use the PUCCH resource to feed back the UCI.

The above-mentioned UE obtains the configuration information of at least one PUCCH resource unit group, which may be according to the agreement, or may be based on the notification from the network side device, or part of the configuration information of at least one PUCCH resource unit group may be determined according to the agreement, and in addition, Part of the information is determined based on the notification from the network side device, and the network side device can notify the above configuration information through high-level signaling.

The above-mentioned PUCCH resource unit group can be configured as one or multiple different groups. Each PUCCH resource unit group includes at least one PUCCH resource. The UEs that use the PUCCH resources in each PUCCH resource unit group are a broadcast multicast service group. , a UE in a broadcast multicast service group can use only one PUCCH resource unit group, or can be allocated to different PUCCH resource unit groups. The UE using each PUCCH resource unit group can be one or multiple. When configuring a PUCCH resource unit group, the PUCCH resource unit group includes multiple PUCCHs, and the multiple PUCCHs can adopt the same format or different formats.

The PUCCH resources in the PUCCH resource unit group may be distributed in one time slot, or may not be in one time slot.

The following embodiment takes the UCI information as HARQ-ACK as an example for explanation. The specific implementation methods of other UCI information are the same, but the difference lies in the content of the UCI information.

As an optional implementation manner, the UE determines the time slot for feeding back the HARQ-ACK codebook according to the scheduling signaling, and based on the configuration information of the PUCCH resource unit group corresponding to the UE, the group number and the HARQ-ACK codebook to be fed back, Determine the PUCCH resources occupied by the HARQ-ACK codebook to be fed back. There is one PUCCH resource unit group corresponding to the UE, which can be configured by the network side. set and indicated to the UE. When multiple UEs are configured in one PUCCH resource unit group, the network side further indicates the group number of the UE in the corresponding PUCCH resource unit group to the UE.

The above configuration information of at least one PUCCH resource unit may include the frequency domain starting position of the PUCCH in the occupied time slot in the PUCCH resource unit group. Furthermore, the number of multiplexed users and PUCCH resources in the PUCCH resource unit group may also be configured. The maximum bit carrying capacity on the. The above-mentioned number of multiplexing users can be a fixed value greater than 1, or 1, or a variable value, and the specific value of the number of multiplexing users is determined by the UE after calculation. By configuring the maximum bit carrying capacity on the PUCCH resource, the number of multiplexed users N on one PUCCH channel can be determined: such as

N1 is the user multiplexing number set when configuring PUCCH, that is, assuming that the number of feedback HARQ-ACK bits is equal to the maximum bit carrying capacity.

As another optional implementation manner, embodiments of the present invention may configure multiple PUCCH resource unit groups. Each PUCCH resource unit group includes multiple PUCCHs. The multiple PUCCHs may adopt the same format or may adopt different formats.

Based on the above PUCCH resource unit group configuration scheme, it can support configuring different PUCCH resource unit groups to meet different feedback requirements. During specific configuration, multiple PUCCH resource unit groups can be configured. Different PUCCH resource units meet different feedback requirements, or configure Multiple PUCCH resource unit group sets, different PUCCH resource unit sets meet different feedback requirements, wherein a PUCCH resource unit group set includes at least one PUCCH resource unit group.

The above network side device indicates to the UE the PUCCH resource unit group corresponding to the UE, and the UE determines the PUCCH resource unit group corresponding to the UE according to the instruction from the network side; or The above network side device indicates to the UE the corresponding PUCCH resource unit group set, and the PUCCH resource unit group corresponding to the UE in the corresponding PUCCH resource unit group set; the UE determines the PUCCH corresponding to the UE according to the instructions from the network side Resource unit group set, and the PUCCH resource unit group corresponding to the UE in the corresponding PUCCH resource unit group set.

Specifically, different PUCCH resource unit groups can be configured to meet different feedback requirements in any of the following ways: multiple PUCCH resource unit groups or sets of PUCCH resource unit groups corresponding to different bit numbers. The number of bits is The number of bits occupied by the UE feedback HARQ-ACK codebook. For example, different PUCCH resource unit groups/PUCCH resource unit group sets can be configured to support HARQ-ACK codebook feedback with different number of bits. For example, a PUCCH resource unit can be configured. Group-0 supports HARQ-ACK codebook feedback in the first range of bits, configured PUCCH resource unit group-1 supports HARQ-ACK codebook feedback in the second range of bits, PUCCH in PUCCH resource unit group-1 The number of RBs in PUCCH is larger, the number of RBs in PUCCH in PUCCH resource unit group-0 is smaller, and the number of bits in the first range is greater than the number of bits in the second range.

Multiple PUCCH resource unit groups or PUCCH resource unit group sets corresponding to different distances. The distance is the distance between the UE and the network side device. For example, a PUCCH resource unit group-0 can be configured for a group of UEs whose distance is less than the set value. Configure PUCCH resource unit group-1 for another group of UEs whose distance is greater than the set value. PUCCH resource unit group-1 occupies a larger number of symbols, and PUCCH resource unit group-0 occupies a smaller number of symbols.

Multiple PUCCH resource unit groups or PUCCH resource unit group sets corresponding to different path losses. The path loss is the path loss corresponding to the HARQ-ACK codebook fed back by the UE.

Further, in order to simplify the implementation of UE and network side equipment, the PUCCH formats in the same PUCCH resource unit group are the same, the number of RBs included in the PUCCH is the same, or the number of symbols occupied by the PUCCH is the same.

The format of the above-mentioned PUCCH resources can adopt the PUCCH frequency domain resource format defined in the existing protocol. Currently, in order to support UE feedback of unicast HARQ-ACK information, 5G has designed five PUCCH frequency domain resource formats, which are briefly introduced below.

As shown in Table 1, it is the frequency domain resource corresponding to PUCCH format 0. PUCCH in this format can be multiplexed with other users. Different initial cyclic shifts (Initial Cyclic Shift) are used to distinguish the multiplexers, which can meet the requirements. A small number of bits are fed back, and UEs closer to the base station perform HARQ-ACK feedback.

As shown in Table 2, it is the frequency domain resource corresponding to PUCCH format 1. PUCCH in this format can be multiplexed with other users. When multiplexing, different initial cyclic shifts (Initial Cyclic Shift) are used to distinguish or use different The orthogonal sequences (Orthogonal Sequences) are distinguished, which can satisfy a small number of bit feedback, and UEs far away from the base station perform HARQ-ACK feedback.

As shown in Table 3, it is the frequency domain resource corresponding to PUCCH format 2. The PUCCH in this format can satisfy more bit feedback. UEs that are closer to the base station perform HARQ-ACK feedback. In actual transmission, the number of RBs used can Less than X RB.

As shown in Table 4, it is the frequency domain resource corresponding to PUCCH format 3/4. The PUCCH in this format can satisfy more bit feedback. UEs far away from the base station perform HARQ-ACK feedback, in which RB is used in actual transmission. The number can be less than X RB.

Among them, Format 4 can perform multiple tasks with other users. Different orthogonal sequences are used to distinguish between multiple tasks.

Figure 4 shows a schematic diagram of the above-mentioned PUCCH format (0/1/2) resources. For specific resource occupation, please refer to the content in the above table, which will not be described in detail here.

Each PUCCH resource unit group configured in this embodiment includes at least one of the following: the number of PUCCH resources; The starting resource block RB position of the PUCCH resource; the format of the PUCCH resource; the number of multiplexed users on the PUCCH resource; the maximum bit carrying capacity on the PUCCH resource.

As shown in Table 5, the content items included in each PUCCH resource unit group are:

As shown in Figure 5, the network side device in the example of the embodiment of the present invention configures 2 PUCCH resource unit groups. Each of the 2 PUCCH resource unit groups includes 3 PUCCHs. Each PUCCH adopts PUCCH format 1, where the PUCCH resource unit group- The PUCCH in 0 is 2 symbols and occupies 2 RBs. The PUCCH in single PUCCH resource unit group-1 is 6 symbols and occupies 2 RBs. Two PUCCH resource unit groups can be in one time slot or in different time slots. There is no Make restrictions. As shown in Figure 6, PUCCH resource unit group-0 can be used for one or a group of UEs to perform HARQ-ACK codebook feedback; PUCCH resource unit group-1 can be used for one or a group of UEs to perform HARQ-ACK codebook feedback.

As an optional implementation manner, the network side device indicates to the UE the time slot offset value of the UE in the corresponding PUCCH resource unit group. The UE determines the time slot offset value of the PUCCH resource unit group corresponding to the UE according to the instructions from the network side; according to the HARQ feedback time slot indicated by the scheduling signaling, and offsets the HARQ feedback time slot by the time slot offset value Finally, the time slot where the PUCCH resource is located is obtained.

The network side device sends broadcast multicast configuration information to the UE, and the UE performs control channel and data channel detection based on the received broadcast multicast configuration information. In implementation, the above broadcast multicast configuration information includes the G-RNTI (Group Radio Network Tempory Identity, Group Radio Network Temporary Identity) of the broadcast multicast service.

It should be noted that the G-RNTI-DCI (Group-Radio Network Tempory Identity-Downlink Control Information) here is a group-based wireless network temporary identity RNTI (Radio Network Tempory Identity), which is used by the UE to broadcast multicast empty channels. The detection, depending on the implementation, may have other names. PUCCH is an uplink control channel, a channel used to transmit HARQ-ACK information. In implementation, it can also be named by another name. G-RNTI-PDSCH (Group-Radio Network Tempory Identity-Physical Downlink Shared channel) is also a group-based wireless network identifier, used to receive and use the data channel PDSCH. During the implementation process, it can also be other names. At the same time, G- RNTI-PDSCH can be the same as or different from G-RNTI-DCI.

Specifically, the network side device allocates RNTI to a specific broadcast multicast service and sends broadcast multicast configuration information. The execution process is as follows: The network side equipment is configured to detect the G-RNTI-DCI of the control channel. The UE uses the received G-RNTI-DCI as the scrambling code detection control channel to receive scheduling signaling through the control channel; the network side equipment is configured to assist in receiving the broadcast group G-RNTI-PDSCH that broadcasts service data (PDSCH data). The UE will receive G-RNTI-PDSCH as a parameter to generate a scrambling sequence, and use the above scrambling sequence to receive broadcast multicast data according to the scheduling signaling.

The above-mentioned G-RNTI-DCI and G-RNTI-PDSCH may be the same (that is, the same parameter), or they may be different.

When the network side device in the embodiment of the present invention sends broadcast multicast configuration information, it can also send the group number of the UE in the broadcast multicast service group at the same time or separately. This group number is used to assist the UE in the used PUCCH resource unit group. , determine the occupied PUCCH resources, and different UEs use different group numbers to avoid conflicts in determining PUCCH resources. Specifically, the value of the group number (i) of the broadcast service group where the UE is located can start from 0, for example, the group number of UE0 is (0), the group number of UE1 is 1, the group number of UE2 is 2, and so on.

As an optional implementation manner, when there are multiple UEs in each PUCCH resource unit group, the network side device sends the above group number to the UE as follows: When a broadcast multicast service group corresponds to a PUCCH resource unit group, the receiving network The number sent by the roadside device indicating the order of each UE in the broadcast multicast service group, and the group number of the UE is determined based on this number; or when a broadcast multicast service group corresponds to multiple PUCCH resource unit groups, the indication sent by the network side device is received The sequential numbers of each UE in the broadcast multicast service group and the bitmap diagram of the PUCCH resource unit group corresponding to each UE do not determine the group number of the UE based on the numbering sequence of the UEs belonging to the same PUCCH resource unit group in the bitmap diagram. , the above dot matrix diagram is arranged according to the number of the UE, and the corresponding bits are used to indicate the corresponding PUCCH resource unit group.

The network side device sends scheduling signaling to the UE through the control channel. The UE receives the broadcast multicast data according to the received scheduling signaling and determines the HARQ-ACK codebook to be fed back. The scheduling signaling includes the following content: Frequency domain resource configuration indication (Frequency domain resource assignment), occupying L bits, used to indicate the bandwidth and location of the frequency domain of the scheduled PDSCH, where the number of occupied bandwidths is related to the total schedulable maximum bandwidth; indicating the time domain resources of the time domain of the scheduled PDSCH Configuration information (Time domain resource assignment), which occupies 4 bits, is information indicating the time domain for scheduling PDSCH; indicates the modulation and coding scheme (Modulation and coding scheme) of the modulation order and channel coding rate used by PDSCH, which occupies 5 bits. Bit; redundancy version used for channel decoding and demodulation, occupying 2 bits, redundancy version number for data transmission, used for channel decoding and demodulation; feedback time of HARQ-ACK codebook Indicator (PDSCH-to-HARQ_feedback timing indicator), which occupies 3 bits, represents the timing of feedback HARQ-ACK, from the start of PDSCH to the time slot of feedback HARQ-ACK.

When the network side device configures multiple PUCCH resource unit groups, the network side device indicates to the UE the PUCCH resource unit group used to feed back the HARQ-ACK codebook, and the UE determines to feed back the HARQ-ACK codebook according to the instructions from the network side. The PUCCH resource unit group used.

The network side device may schedule signaling to indicate the PUCCH resource unit group corresponding to the UE, or may indicate the PUCCH resource unit group corresponding to the UE by broadcasting multicast service group configuration information. The specific process is as follows.

1) The network side device indicates to the UE the PUCCH resource unit group corresponding to the UE by broadcasting the G-RNTI-DCI in the multicast service configuration information; different G-RNTI-DCI corresponds to different PUCCH resource unit groups, and the UE receives After broadcasting the multicast configuration information, according to the corresponding relationship between different G-RNTI-DCI and PUCCH resource unit groups, determine the PUCCH resource unit group corresponding to the G-RNTI-DCI in the broadcast multicast service configuration information, which is the PUCCH corresponding to the UE. The resource unit group is used as the PUCCH resource unit group when feeding back the HARQ-ACK codebook.

2) The network side device indicates to the UE the PUCCH resource unit group used to feed back the HARQ-ACK codebook through the PUCCH resource unit group indication in the scheduling signaling. The UE determines the corresponding PUCCH resource unit group according to the PUCCH resource unit group indication in the scheduling signaling. PUCCH resource unit group.

3) The network side device indicates the corresponding PUCCH resource unit group set to the UE through the G-RNTI-DCI in the broadcast multicast service configuration information, and indicates to the UE through the PUCCH resource unit group indication in the scheduling signaling. The PUCCH resource unit group corresponding to the UE; the UE determines the PUCCH corresponding to the UE based on the corresponding relationship between different G-RNTI-DCI and PUCCH resource unit group sets, and the G-RNTI-DCI in the broadcast multicast service configuration information. The resource unit group set determines the PUCCH resource unit group corresponding to the UE according to the PUCCH resource unit group indication in the scheduling signaling.

For the case where multiple PUCCH resource unit group sets are configured, each PUCCH resource unit group set includes at least one PUCCH resource unit group. In the implementation, different set identifiers are used to distinguish the PUCCH resource unit group sets. For the PUCCH resource unit group set, PUCCH resource unit groups, use different resource unit group identifiers to distinguish different PUCCH resource unit groups, and different resource unit group identifiers in different PUCCH unit sets can be the same.

The following is a specific process for the UE to determine the corresponding PUCCH resource unit group and determine the PUCCH resources occupied by the HARQ-ACK codebook to be fed back based on the group number and the HARQ-ACK codebook to be fed back.

After the UE determines the PUCCH resource unit group used to feed back the HARQ-ACK codebook, it can calculate the PUCCH parameters required to feed back the HARQ-ACK codebook, specifically including: the number of RBs occupied by each PUCCH, the number of PUCCHs required, and the location of the UE. The frequency domain starting position of the PUCCH resource is RB_start1, so that the UE in the group can use the PUCCH resources in the corresponding PUCCH resource group to perform codebook feedback. The calculation of the above PUCCH parameters needs to be based on the following two pieces of information: the configuration information of the PUCCH resource unit group corresponding to the UE (For example, the number of PUCCHs: _M =3, the number of RBs for each PUCCH channel: , as calculated, O _Ack is 5.

，其中，i為該組編號，startRB為所使用的PUCCH資源單元組內起始RB，N為PUCCH資源上多工的使用者數。 Based on the above PUCCH parameters, the UE determines the number of RBs occupied by the feedback HARQ-ACK codebook X1 based on the number of bits O _Ack of the feedback HARQ-ACK codebook and the modulation coding format. X1 here refers to when the number of channel RBs is X1 , can carry O _Ack feedback bits. When the number of RBs is (X1-1), it cannot carry O _Ack feedback bits; after the UE determines X1, calculate the PUCCH resources occupied by the UE in the corresponding PUCCH resource unit group The frequency domain starting position of:

, where i is the group number, startRB is the starting RB in the used PUCCH resource unit group, and N is the number of multiplexed users on the PUCCH resource.

表示向下取整，「/」表示相除。 formula

means rounding down, "/" means division.

As shown in Figure 7, the number of users user_number=6, the number of users that can be multiplexed on the PUCCH is N=1, and the frequency domain starting position of each UE is calculated according to the above formula: UE(0)=0, UE(1 )=1, UE(2)=2, UE(3)=3, UE(4)=4, UE(5)=5.

In the embodiment of the present invention, the UE calculates the number of frequency domain resources occupied by the PUCCH resources according to the number of bits required to feed back the HARQ-ACK codebook in the above manner, which can match the number of resources occupied by the feedback channel with the amount of feedback information, thereby saving resources. Or add a feedback channel. As shown in Figure 7, the network side device is configured with M = 3 channels. Each channel occupies 2RB. According to the existing feedback mechanism, up to 3 UEs can provide feedback. According to the solution of this embodiment, when feedback When the number of bits is small, the channel is reduced to 1RB, which can provide 6 PUCCH feedback channels, thus increasing the feedback capacity of the UE.

If there are too many UEs in the broadcast multicast service group, the PUCCH resources required for feedback exceed the number of channel resources configured by the base station (in the PUCCH resource unit group as shown in Figure 7, if the UEs in the corresponding broadcast multicast service group There are 8 channels. In fact, there are at most 6 channels, so there are two remaining UEs that cannot effectively feedback HARQ-ACK information). When the feedback information is only 1 bit, this embodiment can use the following method for UEs that cannot feedback HARQ-ACK information. Any processing method.

1) Determine the PUCCH occupied by the HARQ-ACK codebook to be fed back. When it exceeds the PUCCH resource unit group corresponding to the UE, use a PUCCH channel in the corresponding PUCCH resource unit group as a public channel, and only ACK information or only ACK information is fed back on the public channel. Feed back NACK information; for the remaining UEs that are not allocated to PUCCH feedback, when the public channel is set to feedback only ACK information, if the UE receives the data correctly, ACK will be fed back on the public channel, otherwise no information feedback will be performed; for those that are not allocated For the remaining UEs that feed back to the PUCCH, when only NACK is set to be fed back on the public channel, if the UE does not receive the data correctly, NACK will be fed back on the public channel, otherwise no information will be fed back.

The UE can determine the public channel according to instructions from the network side or according to the agreement.

2) Determine the PUCCH occupied by the feedback HARQ-ACK codebook. When it exceeds the corresponding PUCCH resource unit group, use the two PUCCH channels in the corresponding PUCCH resource unit group as public channels, and only feedback ACK information on one of the public channels. Only NACK information is fed back on another public channel; for the remaining UEs that are not allocated to PUCCH feedback, if the received data is correct, ACK is fed back on the public channel that feeds back ACK; if the reception error is received, NACK is fed back on another public channel.

The UE can determine the public channel according to instructions from the network side or according to the agreement.

3) Does not return any HARQ-ACK information.

Embodiments of the present invention support the design of different PUCCH resource unit groups to effectively solve the problem of different demands for feedback resources at different distances between the UE and the base station, and improve the reliability of feedback HARQ-ACK. At the same time, based on the actual transmitted feedback information bits, the resource requirement RB number of the channel in the resource group is calculated, effectively saving air interface resources.

From the perspective of interaction between the network side device and the UE, possible implementation methods for the network side device to configure PUCCH resources and the UE to determine the PUCCH resources in the embodiment of the present invention are given below.

Embodiment 1

In this embodiment, it is assumed that a PUCCH resource unit group is configured. The format of the PUCCH resources in the PUCCH resource unit group is configured as PUCCH format 1. The multiplexing user on each PUCCH is variable (that is, the number of feedback bits on each PUCCH channel is adjusted according to the actual number of feedback bits. number of users).

The HARQ codebook feedback process in this embodiment is as follows:

Step 1: The UE receives one or more PUCCH resource unit groups configured by the base station, which are used for one or more groups of UEs to feedback HARQ-ACK codebook information; the base station configures one group of uplink PUCCH resource unit group-0, as shown in the table As shown in 6, it includes the following contents:

Figure 8 shows a schematic diagram of a defined PUCCH unit resource group, with M=4 (4 PUCCH channels). startRB=0 (the starting position of the resource group is RB0), each PUCCH channel occupies 1 RB, and the number of symbols is 4. Number of multiplexing users on each PUCCH resource: N=2 or N=4. Among them: when the feedback HARQ-ACK codebook information is 1 bit, 4 UEs are multiplexed, and the initial loop displacement index corresponding to the 4 UEs is {0,3,6,9}. Initial cyclic shift indexes (initial cyclic shift indexes) are parameters used to distinguish users on the same PUCCH channel and can be consistent with the definition in 3GPP NR.

When the feedback HARQ-ACK codebook information is 2 bits, two users are multiplexed, and the initial loop displacement index corresponding to the two UEs is {0,6}.

The following two points need to be explained here: the initial loop displacement index value can be other values (such as obtained through different orthogonal sequence indexes), and the configuration parameters may not be {0, 6} or {0, 3, 6 ,9}, as long as different UEs can be distinguished.

The above configuration information can be configured through dedicated signaling (such as RRC messages), or through public signaling, such as BCCH (Broadcast Control Channel, broadcast control channel), or MCCH (Multicast Control Channel) multicast channel configuration.

Step 2: The UE receives the broadcast multicast service group configuration information sent by the base station, which mainly includes the following processes.

A. The base station sends the RNTI configuration information of the broadcast multicast service group.

The above RNTI configuration information includes G-RNTI-DCI used to detect the control channel, and G-RNTI-PDSCH used to receive the broadcast multicast service PDSCH. The UE uses G-RNTI-DCI as a scrambling code to detect the control channel, using G -RNTI-PDSCH is used as a parameter to generate the scrambling sequence of the service channel.

G-RNTI-DCI and G-RNTI-PDSCH can be the same (that is, the same parameter), or they can be different. It is assumed here that within the coverage community of the base station, all UEs are at the same distance from the base station or the base station does not differentiate and only uses one DCI to schedule PDSCH. At this time, G-RNTI-DCI and G-RNTI-PDSCH are the same parameters. .

B. The base station sends the group number information of the UE in the corresponding PUCCH resource unit group.

In this embodiment, UEs in a broadcast multicast service group are allocated to a PUCCH resource unit group, and the group number can start from 0. For example, the group number of UE0 is 0, the group number of UE1 is 1, and so on.

Step 3: The UE receives the scheduling signaling and calculates the number of feedback bits of HARQ-ACK.

Scheduling signaling is a broadcast multicast service scheduling signaling sent by the base station. Based on the existing standard protocol, it determines the number of HARQ-ACK bits of the broadcast multicast that the UE needs to feedback. It supports the semi-static codebook and dynamic coding in the existing NR protocol. codebooks, and enhanced dynamic codebooks, or other types of codebooks.

Please refer to the above description for the content of broadcast multicast scheduling signaling, which will not be repeated here. This embodiment assumes that K=1, that is, only one PUCCH resource unit group-0 is configured, that is, Y=0 bits, so there is no need to The scheduling signaling carries a PUCCH resource unit group indication.

After calculation, the number of bits that need to be fed back is: O _ACK . Assume that there are two situations: O _ACK =1, O _ACK =2.

Step 4: Determine the PUCCH resources of the HARQ-ACK codebook to be fed back based on the PUCCH resource unit group corresponding to the UE, the group number (i) of the UE, and the number of bits fed back by HARQ-ACK.

Receive PDSCH according to the scheduling signaling and feed back HARQ-ACK on the designated PUCCH resource.

In this implementation, the group number (i) of the UE can be configured through high-level messages. Specifically, the base station sends the number information to the UE. Assume that there are a total of user_number=8 users, UE0 corresponds to group number 0, and UE1 corresponds to group number 1.. .UE7 corresponds to group number 7.

At the same time, for the flexibility of base station scheduling, K PUCCH resource unit groups-0 can be configured, then the PUCCH resource unit group indication The number of bits required is log ₂ (K), and the upper limit of the integer is taken. K is a positive integer greater than 1.

Embodiment 2

In this embodiment, a multi-DCI scheduling method is adopted. Each DCI is targeted at a group of UEs at a similar distance. The network side device configures multiple PUCCH resource unit groups. The distances between the UEs corresponding to different broadcast multicast service groups and the network side device are Different, or the path loss is different, the distance difference between a group of PUCCH resource unit groups corresponding to the UE and the network side device is within the set range, or the path loss difference is within the set range. The above-mentioned network side equipment is a base station, and the codebook feedback process of the UE is as follows.

Step 1: The UE receives one or more PUCCH resource unit groups configured by the base station, which are used for one or more groups of UEs to feed back HARQ-ACK codebook information.

Taking the base station configured with two PUCCH resource unit groups as an example, the UE groups corresponding to different resource unit groups are at different distances from the base station, or have different path losses to the base station.

The PUCCH resource unit group-0 parameters configured by the base station are shown in Table 7:

The parameter configuration of PUCCH using format 2 is shown in Table 8:

The PUCCH resource unit group-1 parameters configured by the base station are shown in Table 9: Table 9 Configuration information of PUCCH resource unit group-1

The parameter configuration of PUCCH using format 3 is shown in Table 10:

Figure 11 shows a schematic diagram of two PUCCH resource unit groups configured in this embodiment. It should be noted that these two PUCCH resource unit groups can be in one time slot or in In different time slots, there are no restrictions here. In addition: In order to simplify the implementation of terminals and base stations, the PUCCH channel formats within the PUCCH unit resource group are the same.

When indicated to the UE in a broadcast manner, more than two PUCCH unit resource group configuration information can be carried on the BCCH or MCCH and indicated to the UE.

Step 2: The UE receives the broadcast multicast service group configuration information sent by the base station.

A. For the RNTI allocated by the base station to a specific broadcast multicast service, please refer to the description of Embodiment 1 for details. The G-RNTI-DCI and G-RNTI-PDSCH here may be the same (that is, the same parameter) or different.

When the above broadcast multicast service group configuration information is directed to the UE through broadcasting, multiple different G-RNTI-DCIs (such as: G-RNTI-DCI-1, G-RNTI-DCI-2, etc.) may be indicated in the broadcast information. G-RNTI-DCI-3), and also needs to use dedicated signaling to indicate which G-RNTI-DCI to use when the UE performs channel detection.

When the above broadcast multicast service group configuration information is indicated to the UE through dedicated signaling, the dedicated signaling indicates a G-RNTI-DCI (such as: G-RNTI-DCI-1, or G-RNTI-DCI-2, or G -RNTI-DCI-3), and a G-RNTI-PDSCH.

B. The base station sends the group number information of the UE in the corresponding PUCCH resource unit group.

In this embodiment, the UE in a broadcast multicast service group uses multiple PUCCH resource unit groups. The number of the UE in the broadcast multicast service group can be assigned to the PUCCH resource unit group correspondingly, and it is determined that the UE is in the corresponding PUCCH resource unit. group number. The number (i) can start from 0, for example, the number of UE0 is 0, the number of UE1 is 1, and so on.

For example, if a total of 12 UEs are interested in a specific broadcast multicast service, after interacting with the base station and configuring information, content as shown in Table 11 can be generated.

Through the above configuration, different DCIs schedule UEs in different broadcast multicast service groups. Specifically, the scheduling of UEs in different broadcast multicast service groups according to DCI and the location of HARQ feedback PUCCH resources are shown in Figure 12.

Step 3: The UE receives the scheduling signaling and calculates the number of feedback bits of HARQ-ACK.

Scheduling signaling is a broadcast multicast service scheduling signaling sent by the base station. Based on the existing standard protocol, it determines the number of HARQ-ACK bits of the broadcast multicast that the UE needs to feedback. It supports the semi-static codebook and dynamic coding in the existing NR protocol. codebooks, and enhanced dynamic codebooks, or other types of codebooks. Assume that the number of bits that need to be fed back after calculation is: O _ACK , and it is assumed that the number of bits that need to be fed back is: O _ACK =5.

Step 4: Determine the PUCCH resources of the HARQ-ACK codebook to be fed back based on the PUCCH resource unit group corresponding to the UE, the group number (i), and the number of bits fed back by HARQ-ACK.

Before receiving the scheduling signaling, the base station's dedicated signaling (such as through DCCH) indicates the PUCCH resource unit group and number (i) where the UE is located. It is assumed here that there are a total of user_number=6 users, UE0 corresponds to number 0, and UE1 corresponds to number 1 ...UE5 corresponds to number 5.

The UE receives the scheduling signaling sent by the base station (assuming the control signaling detected by G-RNTI-DCI-1), receives the PDSCH according to the scheduling signaling and feeds back HARQ-ACK on the designated PUCCH resource.

For the content of scheduling signaling, please refer to the description of the above embodiments, which will not be repeated here. It should be noted that since the PUCCH resource unit group has been configured in the dedicated signaling, in this embodiment, the PUCCH resource unit group indication in the scheduling signaling is 0 bits.

Calculate the PUCCH parameters required to feed back HARQ-ACK, including: the number of RBs occupied by each PUCCH, the number of required PUCCHs, and the frequency domain starting position RB_start1 of the PUCCH resource where the UE is located.

Required relevant parameters include: PUCCH resource unit group configured in step 1 (number of RBs for each PUCCH channel: X=2, number of PUCCHs included: M=3, number of multiplexed users N=1); Step 2 The number of HARQ-ACK bits in O _ACK is assumed to be 5; calculate the number of frequency domain RBs X1 required for each PUCCH: The UE selects the appropriate number of RBs X1 based on O _ACK and the configured modulation order and code rate. The appropriate number of RBs X1 means that when the number of channel RBs is X1, it can carry O _ACK feedback bits. When the number of channel RBs is (X1-1), it cannot carry O _ACK feedback bits.

Assume that the number of RBs required after calculation is X1=1 RB.

。 Calculate the frequency domain starting position of the PUCCH resource where the UE is located:

.

It means rounding down, and "/" means division.

Assume that the number of users user_number=6, N=1, according to RB_strat1=i*1RB+RB_start: UE(0)=0, UE(1)=1, UE(2)=2, UE(3)=3, UE(4)=4,UE(5)=5.

The specific PUCCH resource occupation diagram is shown in Figure 7.

Further, DCI-RNTI-1 corresponds to the configured PUCCH resource unit group-0, and DCI-RNTI-2 corresponds to the configured PUCCH resource unit group-1. Therefore, the number of resource unit group indication bits in the scheduling signaling is 0. At the same time, For base station scheduling flexibility, K PUCCH resource unit groups-0 can be configured as the first resource unit group set or K PUCCH resource unit groups-1 as the second resource unit group set. The PUCCH resource unit group indicates the required bits The number is log ₂ (K), and the upper limit of the integer is taken. In this way, the PDCCH detected by the UE through DCI-RNTI-1 only indexes the corresponding configured PUCCH resource unit group.

Further, in order to satisfy the requirement of indicating a larger number of HARQA-ACK feedback bits O _ACK , the base station can configure different PUCCH resource units in sets. Each set corresponds to a different number of feedback bits O _ACK . Each resource unit set contains a Or multiple PUCCH resource unit groups, examples are as follows.

2。 PUCCH resource unit group set (0): includes 4 PUCCH resource unit groups (PUCCH resource unit group-0, PUCCH resource unit group-1, PUCCH resource unit group-2, PUCCH resource unit group-3), supporting feedback bits 0< _OACK

2.

16； 當UE回饋HARQ-ACK時，可以根據DCI-RNTI確定使用的資源單元集合。如小於等於2bit選擇PUCCH資源單元組集合(0)，大於2bit選擇PUCCH資源 單元組集合(1)，然後根據PUCCH資源單元組指示選擇資源單元組。 PUCCH resource unit group set (1): includes 4 PUCCH resource unit groups (PUCCH resource unit group-0, PUCCH resource unit group-1, PUCCH resource unit group-2, PUCCH resource unit group-3), supporting feedback bits 2< _OACK

16; When the UE feeds back HARQ-ACK, the set of resource units used can be determined based on the DCI-RNTI. If it is less than or equal to 2 bits, select the PUCCH resource unit group set (0), and if it is greater than 2 bits, select the PUCCH resource unit group set (1), and then select the resource unit group according to the PUCCH resource unit group indication.

Embodiment 3

In this embodiment, multiple PUCCH resource unit groups are configured. In the corresponding multiple UE groups, the distance between the UE and the base station is different or the path loss is different. The specific HARQ-ACK process is as follows:

Step 1: The UE receives one or more PUCCH resource unit groups configured by the base station, which are used to feed back HARQ-ACK information to one or more groups of UEs; the base station configures two or more PUCCH resource unit groups, each resource unit The groups correspond to different UEs. As shown in Table 12, the PUCCH resource unit group-0 parameters configured by the base station are as follows:

The parameter configuration of the above PUCCH using format 2 is shown in Table 13:

In addition, in order to further increase the flexibility of feedback channel scheduling, the instruction pucch_slot_offset is added. This value represents the offset relative to the time slot indicated by the "HARQ feedback time indication" in the scheduling signaling. For example: the UE receives the broadcast multicast PDSCH in time slot n, the HARQ feedback time indication information in the scheduling signaling is k1, and the time slot in which the UE feeds back HARQ-ACK on the PUCCH is: n+k1+pucch_slot_offset. When not configured by default, pucch_slot_offset=0.

pucch_slot_offset can be indicated in scheduling signaling or in high-layer signaling. This embodiment assumes that it is indicated in higher layer signaling and pucch_slot_offset=0.

The PUCCH resource unit group-1 parameters configured by the base station are shown in Table 14:

The above PUCCH parameter configuration using format 3 is shown in Table 15:

In addition, in order to further increase the flexibility of feedback channel scheduling, pucch_slot_offset is further indicated. This value represents the relative value to the "HARQ feedback time indication" in the scheduling signaling. The offset of the time slot. For example: the UE receives the broadcast multicast PDSCH in time slot n, the "HARQ feedback time indication" information in the scheduling signaling is k1, and the time slot in which the UE feeds back HARQ-ACK on the PUCCH is: n+k1+pucch_slot_offset . When not configured by default, pucch_slot_offset=0.

pucch_slot_offset can be indicated in scheduling signaling or in high-layer signaling. This embodiment assumes that it is indicated in high-layer signaling and pucch_slot_offset=1.

Figure 11 shows a schematic diagram of two PUCCH resource unit groups configured in this embodiment.

When the above configuration information is indicated in a broadcast manner, more than two PUCCH unit resource group configuration information can be carried on the BCCH or MCCH and indicated to the UE.

Step 2: The UE receives the broadcast multicast service group configuration information sent by the base station.

A. The base station sends the RNTI configuration information of the broadcast multicast service group.

For the content of RNTI configuration information, please refer to the description of Embodiment 1, which will not be repeated here. This embodiment uses one scheduling signaling to schedule PDSCH (that is, uses one G-RNTI-DCI). For the PUCCH resource unit group used by the UE and the UE in The number within the broadcast service group is sent through dedicated signaling. Therefore, G-RNTI-DCI and G-RNTI-PDSCH in this implementation are the same.

B: The base station sends the group number information of the UE in the corresponding PUCCH resource unit.

In order to better adapt to changes in terminal location and adjust the PUCCH resource unit group corresponding to the UE in a timely and effective manner, this embodiment is divided into two steps: Step 1, indicating the number (k) of the broadcast multicast service group where the UE is located. The number can be Starting from 0, for example, the number of UE0 is 0, the number of UE1 is 1, the number of UE2 is 2, and the number of UEx is The UE combines the above number with the corresponding PUCCH resource unit information to obtain the group number of the UE in the corresponding PUCCH resource unit group. The specific indication method is as follows: When a broadcast multicast service group corresponds to multiple PUCCH resource unit groups, receive a bitmap sent by the network side device indicating the sequence number of each UE in the broadcast multicast service group and the PUCCH resource unit group corresponding to each UE, according to the bitmap that belongs to the same The numbering sequence of the UEs in the PUCCH resource unit group in the dot diagram determines the group number of the UE.

When the PUCCH resource unit group is divided into 2 groups, the PUCCH resource unit group bitmap is [X] bit, X is the number of UEs in step 1, and each bitmap indicates a value of 0 or 1. 0 indicates the corresponding UE In PUCCH resource unit group 0,1, it means that the corresponding UE is in PUCCH resource unit group 1, or vice versa. At the same time, the number of each UE in the PUCCH resource unit group increases in the order indicated by the bitmap.

Figure 13 shows a dot matrix diagram of two PUCCH resource unit groups, in which there are 6 UEs in a broadcast multicast service group, UE0, UE1, UE2...UE5.

In Step 1, the UE numbers (k) in the broadcast multicast service group are: UE0=0, UE1=1, UE2=2, UE3=3, UE4=4, UE5=5.

In Step 2, the bitmap indication is 001101, 0 means that the UE corresponding to number k is configured as PUCCH resource unit group-0, 1 means that the UE corresponding to number k is configured as PUCCH resource unit group-1, and the corresponding UE is in the corresponding PUCCH resource The group number (i) of the unit group is:

PUCCH resource unit group-0: UE0, UE1, UE4. The group numbers in the corresponding PUCCH resource unit group are: 0, 1, 2.

PUCCH resource unit group-1: UE2, UE3, UE5. The group numbers in the corresponding PUCCH resource unit group are: 0, 1, 2.

Among the above steps, step 1 can use high-level signaling method for semi-static configuration, and the update interval is longer. Step 2 can use physical layer indication or high-level signaling indication, and the update interval period is short to adapt to changes in the distance between the UE and the base station and changes in feedback channel quality.

Step 3: The UE receives the scheduling signaling and calculates the number of feedback bits of HARQ-ACK.

Scheduling signaling is a broadcast multicast service scheduling signaling sent by the base station. Based on the existing standard protocol, it determines the number of HARQ-ACK bits of the broadcast multicast that the UE needs to feedback. It supports the semi-static codebook and dynamic coding in the existing NR protocol. codebooks, and enhanced dynamic codebooks, or other types of codebooks. Assume that the number of bits that need to be fed back after calculation is: O _ACK .

Step 4: Determine the PUCCH resources of the HARQ-ACK codebook to be fed back, and the feedback time slot according to the configured PUCCH resource unit group, group number (i), and the number of bits to be fed back by HARQ-ACK.

For the content of the broadcast multicast scheduling signaling sent by the base station when the UE receives it, please refer to the description of the above example. It will not be repeated here. According to the scheduling signaling, it receives the broadcast multicast data and determines the HARQ-ACK codebook that needs to be fed back, and performs the following calculations. :

A: Calculate the time slot position of the feedback PUCCH; the required parameter is the pucch_slot_offset of each PUCCH resource unit group configured in step 1. (Resource unit group-0 pucch_slot_offset=0, resource unit group-1 pucch_slot_offset=1.).

HARQ feedback time indication in scheduling signaling, assuming k1=3.

The uplink slot position corresponding to the received PDSCH: assumed to be slot n.

Grouping information in step 2: PUCCH resource unit group-0: UE0, UE1, UE4, the group numbers in the corresponding PUCCH resource unit group are: 0, 1, 2; PUCCH resource unit group-1: UE2, UE3, UE5, the numbers in the corresponding PUCCH resource unit group are: 0, 1, 2.

The time slot position of feedback PUCCH is: slot n+k1+pucch_slot_offset. That is, the uplink time slot corresponding to PDSCH reception plus k1 plus the offset. The feedback time slot position in this example is shown in Figure 14. The PUCCH time slot position of the UE in PUCCH resource unit group-1 is shifted backward by 1 time slot.

B: PUCCH parameters needed to feed back HARQ-ACK; PUCCH parameters needed to feed back HARQ-ACK, including: the number of RBs occupied by each PUCCH, the number of required PUCCHs, and the frequency domain starting position RB_start1 of the PUCCH resource where the UE is located.

Here, PUCCH resource unit group-1 is taken as an example. The calculation method of PUCCH resource unit group-0 is the same and will not be repeated.

Calculate the relevant parameters required for the above PUCCH: PUCCH resource unit group configured in step 1 (number of RBs for each PUCCH channel: X=2, number of PUCCHs included: M=3, number of multiplexed users N=1); The number of HARQ-ACK bits O _ACK in step 2 is assumed to be 5; calculate the number of frequency domain RBs X1 required for each PUCCH: The UE selects the appropriate number of RBs X1 based on O _ACK and the configured modulation order, code rate, etc. The appropriate number of RBs X1 here means that when the number of channel RBs is X1, it can carry O _ACK feedback bits; when the number of channel RBs is (X1-1), it cannot carry O _ACK feedback bits.

Assume that the number of RBs required after calculation is X1=1 RB.

。 Calculate the frequency domain starting position of the PUCCH resource where the UE is located:

For example: user_number=6, N=1, the schematic diagram of the PUCCH resources occupied by the UE is shown in Figure 7.

RB_strat1=i*1RB+RB_start.

The calculation results are UE(0)=0, UE(1)=1, UE(2)=2, UE(3)=3, UE(4)=4, UE(5)=5.

Supplementary explanation of the technical solution of this embodiment: This embodiment configures a "PUCCH resource unit group-0" and a "PUCCH resource unit group-1". If the instructions are broadcast through multicast configuration information, the PUCCH in the scheduling signaling The number of bits indicated by the resource unit group is 0. At the same time, for the flexibility of base station scheduling, the base station can also configure multiple "PUCCH resource unit groups-0", such as configuring K "PUCCH resource unit groups-0" and K "PUCCH resource unit group-1", then the number of bits required for the total PUCCH resource unit group indication in scheduling signaling is log ₂ (M), and the upper limit of the integer is taken.
