Description
本發明屬於通信技術領域,尤其是關於一種配置和確定PUCCH(Physical Uplink Control Channel,實體上行鏈路控制信)資源的方法、使用者終端、網路側設備、裝置及電腦程式介質。 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.
隨著行動視頻服務、對等組播/廣播流服務的發展,通過行動網路的軟體升級,群組通信以及廣播/組播LoT(Internet Of Things,物聯網)應用的日益普及,全球行動通信業界達成共識,將來的第五代行動通信5G網路需要具備在單播型服務及組播型服務間靈活、動態地進行無線頻譜及網路資源配置的能力,並需要支援對於廣播/組播網路的獨立部署。 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.
在當前的5G中,基地台向終端發送的資料包括兩種資料類型:一種是面向終端的資料,該資料只有目標終端才能接收到,這種資料成為單播資料;另一種是面向本社區內所有終端或者特定群組的資料,即社區內的所有使用者或者特定群組使用者能夠接收該服務。 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.
為了保障資料的通信品質,對於發送廣播組播服務資料,需要UE進行UCI(Uplink Control Information,上行控制資訊)如HARQ-ACK(Hybrid Automatic Repeat Request-ACK Nowledgement,混合自動重傳請求確認)回饋, HARQ-ACK的回饋是基於資料接收結果的回饋資訊,當資料接收正確時回饋ACK(即正確接收確認),當資料接收不正確時回饋NACK(即資料未正確接收確認)。 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).
對於現有技術,基於單播的HARQ調度過程,只適合一個接收UE做HARQ-ACK回饋,但對於廣播組播服務,接收該服務的是一組UE或者社區內的所有UE,因此現有單播的HARQ調度及回饋指示機制,不適合基於蜂窩的廣播組播回饋。 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.
對於現有技術,基於邊鏈路的HARQ調度過程中回饋NACK/ACK的過程,需要對所有UE進行分配上行回饋資源,會有兩個問題:一是接收端UE處於和基地台的位置不同,為了有效回饋HARQ-ACK,有的需要佔用2個符號,有的需要佔用4個符號,甚至有的需要佔用14個符號,而現有方案的上行回饋資源配置是統一的一種格式,無法滿足蜂窩的回饋HARQ-ACK的需求;二是當前設計只支持1位元的回饋,當廣播組播的服務需要回饋多位元的HARQ-ACK回饋資訊時(如UE接收多個PDSCH(Physical Downlink Shared channel,實體下行共用通道)資料包,在一個PUCCH上回饋),當前技術無法滿足上述要求。 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.
可見目前調度信令機制,無法讓UE有效的回饋HARQ-ACK編碼簿資訊,對於HARQ-ACK編碼簿外其他UCI控制資訊,同樣存在目前調度信令無法滿足UE回饋需求的問題。 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.

目前HARQ-ACK(Hybrid Automatic Repeat Request-ACK Nowledgement,混合自動重傳請求確認)回饋機制主要有單播服務的HARQ-ACK回饋及邊鏈路side link的廣播組播服務的HARQ-ACK的回饋,具體如下該。 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.
一、基於單播服務的HARQ-ACK回饋機制 1. HARQ-ACK feedback mechanism based on unicast service
在無線通訊的環境中,由於通道品質是快速變化的,即資料的傳輸有可能發生錯誤,為提高資料傳輸的可靠性,滿足不同服務不同傳輸品質的要求。標準採用混合自動重傳HARQ過程,也就是接收端對接收到的資料進行解碼,並將解碼結果回饋給發送端,當解碼結果正確時,回饋ACK資訊,當解碼錯誤時,回饋NACK資訊。資料發送端根據接收到的解碼回饋資訊,確定是否進行資料重新傳輸,一般的,當資料發送端收到的回饋資訊是NACK資訊時,進行資料重傳,當接收到的回饋資訊是ACK資訊時,不進行資料重傳,本次資料傳輸結束。 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.
具體的HARQ過程描述如圖1所示,假設初次傳輸解碼錯誤,二次傳輸解碼正確,具體的HARQ過程如下:1)發送端gNB初次發送資料傳輸區塊TB1(Transport Block,傳輸區塊)給接收端UE,並指示UE回饋HARQ-ACK的PUCCH(Physical Uplink Control Channel,實體上行鏈路控制信的時槽和頻域資源資訊; 2)接收端UE對TB1進行解碼,解碼結果為錯誤,在指定時槽的PUCCH資源上回饋NACK給發送端;3)發送端gNB收到NACK資訊,表明UE沒有正確接收到TB1,則對資料傳輸區塊TB1重新發送(即重傳),並指示UE回饋HARQ-ACK的PUCCH的時槽和頻域資源資訊;4)接收端UE對TB1再次進行解碼(UE可能會和前一次的資料進行合併),解碼結果為正確,回饋ACK給資料發送端,發送端在指定時槽的PUCCH資源上回饋ACK資訊給資料發送端。 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.
發送端收到ACK資訊後,確定UE正確接收到TB1,此次資料發送過程完成。 After the sending end receives the ACK information, it determines that the UE has correctly received TB1, and the data sending process is completed.
如圖2所示,為HARQ過程中資料調度及HARQ-ACK回饋通道示意圖,相關內容具體描述如下所述。 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)發送端gNB在時槽slot n中,在PDCCH(Physical Downlink Control Channel,實體下行控制通道)上發送資料調度資訊,調度資訊包括如下內容:資料通道的時域和頻域位置:圖中k0表示資料通道相對於控制通道的偏移時槽數,即PDSCH和PDCCH時槽的距離。當k=0時,表示和PDCCH在同一個時槽,當k0=1時,表示PDSCH在PDCCH所在時槽的後一個時槽,圖2中假設k0為2。 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.
資料通道的調製和編碼格式:表示PDSCH採用的調製階數以及通道編碼速率。 Modulation and coding format of data channel: Indicates the modulation order and channel coding rate adopted by PDSCH.
回饋HARQ-ACK的時域資訊:表示HARQ-ACK的回饋時槽距離PDSCH的位置,當k1=0時,表示和PDSCH在一個時槽中回饋,圖2中k1=4。 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.
回饋HARQ-ACK資訊在指定時槽的PUCCH的頻域資源。 Feed back HARQ-ACK information in the frequency domain resources of the PUCCH in the specified time slot.
2)接收端UE在時槽slot n中,檢測PDCCH,並根據PDCCH上傳輸的資料調度資訊接收PDSCH資料,進行資料的解調和解碼,並將解碼結果(如果解碼正確,回饋ACK,如果解碼錯誤,回饋NACK)在指定時槽的PUCCH頻域資源上回饋給基地台。 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.
二、side link的廣播組播服務的HARQ-ACK的回饋機制 2. HARQ-ACK feedback mechanism of side link broadcast multicast service
Side link是基於終端到終端的通訊連結,對於Sidelink廣播組播通信來說,主要就是方案是基於HARQ ACK/NACK的回饋方式:在這種方式下每個接收UE(Rx UE)都有自己獨立的PSFCH(Physical Side Feedback Channel,實體邊鏈路回饋通道)資源,每個Rx UE根據自己是否正確接收PSSCH(Physical Side Shared Channel,實體邊鏈路共用通道),從而在對應的PSFCH資源上發送HARQ ACK/NACK資訊。 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.
上述方案主要的應用場景是組內UE比較少的時候,且只支持1位元的HARQ-ACK回饋。 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.
可見目前基地台發送廣播組播資料時,發送的是基於群組的調度消息,當UE需要回饋HARQ-ACK時,現有空口的調度信令機制,無法讓UE有效的回饋HARQ-ACK資訊,同樣,對除HARQ-ACK外其他UCI(Uplink Control Information,上行控制資訊)也存在無法滿足UE回饋需求的問題。 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.
針對目前空口的調度信令機制無法滿足UE回饋UCI需求的問題,本發明實施例提供了一種解決方案,提出配置至少一個PUCCH資源單元,用於 一組或多組UE進行DCI回饋,上述UCI可以為HARQ-ACK,也可以為CSI(Channel State Information,通道狀態資訊),或者可以是HARQ-ACK和CSI,或者其它上報給網路側設備的資訊。相應地,進行DCI回饋時的位元數,可以對應是終端的HARQ-ACK位元數、對應CSI的位元數,或者HARQ-ACK的位元數加上CSI的位元數。 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.

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.
作為一種可選的實施方式,網路側設備向該UE指示該UE在對應的PUCCH資源單元組的時槽偏移值。UE根據網路側的指示,確定該UE對應的PUCCH資源單元組的時槽偏移值;根據該調度信令指示的HARQ回饋時槽,並將該HARQ回饋時槽偏移該時槽偏移值後,得到PUCCH資源所在的時槽。 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.

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.
需要說明的是,這裡的G-RNTI-DCI(Group-Radio Network Tempory Identity-Downlink Control Information)是基於組的無線網路臨時標識RNTI(Radio Network Tempory Identity),用於UE對廣播組播空通道檢測,在實施中,可以是其它名稱。PUCCH是上行控制通道,用於傳輸HARQ-ACK資訊的通道,在實施中,也可以是其它名稱。G-RNTI-PDSCH(Group-Radio Network Tempory Identity-Physical Downlink Shared channel)也是基於組的無線網路標識,用於對資料通道PDSCH接收使用,在實施過程中,也可以是其他名稱,同時G-RNTI-PDSCH可以和G-RNTI-DCI相同或者不同。 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.

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.
上述G-RNTI-DCI和G-RNTI-PDSCH可以相同(即同一個參數),也可以不同。 The above-mentioned G-RNTI-DCI and G-RNTI-PDSCH may be the same (that is, the same parameter), or they may be different.

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.

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.

下面給出UE確定對應的PUCCH資源單元組後,根據組編號及需回饋的HARQ-ACK編碼簿,確定回饋該HARQ-ACK編碼簿佔用的PUCCH資源的具體過程。 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.
UE確定回饋該HARQ-ACK編碼簿所使用的PUCCH資源單元組後,可以計算出回饋HARQ-ACK編碼簿需要的PUCCH參數,具體包括:每個PUCCH佔用的RB數,需要PUCCH的數量,UE所在PUCCH資源的頻域起始位置RB_start1,從而實現組內UE利用對應的PUCCH資源組中PUCCH資源進行編碼簿回饋,計算上述PUCCH參數需要基於以下兩個資訊:UE對應的PUCCH資源單元組的配置資訊(如包含PUCCH個數:M=3,每個PUCCH通道的RB數:X=2,多工的使用者數N=1);UE計算的回饋HARQ-ACK編碼簿需要的位元數OAck,如計算得到OAck為5。 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.
基於上述PUCCH參數,UE根據回饋的HARQ-ACK編碼簿的位元數OAck和調製編碼格式,確定回饋HARQ-ACK編碼簿佔用的RB數X1,這裡的X1是指,通道RB數為X1時,能夠承載OAck個回饋位元,當RB數為(X1-1)時,就不能承載OAck個回饋位元;UE確定X1後,計算UE在對應的PUCCH資源單元組中佔用的PUCCH資源的頻域起始位置:,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.

如圖7所示,使用者數user_number=6,PUCCH上可多工的使用者數N=1,根據上述公式計算各UE的頻域起始位置為:UE(0)=0,UE(1)=1,UE(2)=2,UE(3)=3,UE(4)=4,UE(5)=5。 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.
本發明實施例中UE根據回饋HARQ-ACK編碼簿需要的位元數,按照上述方式計算PUCCH資源佔用的頻域資源數,可以讓回饋通道佔用的資源數和回饋信息量相匹配,從而節約資源或者增加回饋通道,如圖7中,網路側設備配置了M=3個通道,每個通道佔用2RB,按照現有回饋機制可最多供3個UE進行回饋,而根據本實施例的方案,當回饋bit數較少時,通道減少到1RB,可提供6個PUCCH回饋通道,從而增大了UE的回饋容量。 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.
如果廣播組播服務組內的UE過多,在進行回饋時需要的PUCCH資源,超過了基地台配置的通道資源數(如圖7的PUCCH資源單元組中,若對應的廣播組播服務組內UE有8個,實際最多有6個通道,則有兩個剩餘UE無法有效回饋HARQ-ACK資訊),當回饋資訊只有1位元時,本實施例對於不能夠回饋HARQ-ACK的UE可以採用如下任一處理方法。 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)確定回饋HARQ-ACK編碼簿佔用的PUCCH,超出UE對應的PUCCH資源單元組時,將對應的PUCCH資源單元組中的一個PUCCH通道作為公共通道,在該公共通道上僅回饋ACK資訊或僅回饋NACK資訊;對於沒有分配到PUCCH回饋的剩餘UE,當在公共通道上設置為僅回饋ACK資訊時,如果UE接收資料正確,則在公共通道上回饋ACK,否則不進行資訊回饋;對於沒有分配到PUCCH回饋的剩餘UE,當在公共通道上設置僅回饋NACK時,如果UE沒有正確接收資料,則在公共通道上回饋NACK,否則不進行資訊回饋。 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.
UE可以根據網路側的指示確定公共通道,也可以根據協定約定確定公共通道。 The UE can determine the public channel according to instructions from the network side or according to the agreement.
2)確定回饋HARQ-ACK編碼簿佔用的PUCCH,超出對應的PUCCH資源單元組時,將對應的PUCCH資源單元組中的兩個PUCCH通道作為公共通道,在其中一個公共通道上僅回饋ACK資訊,在另一個公共通道上僅回饋NACK資訊;對於沒有分配到PUCCH回饋的剩餘UE,如果接收資料正確,則在回饋ACK的公共通道上回饋ACK;如果接收錯誤,則再另外一個公共通道回饋NACK。 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.
UE可以根據網路側的指示確定公共通道,也可以根據協定約定確定公共通道。 The UE can determine the public channel according to instructions from the network side or according to the agreement.
3)不回饋任何HARQ-ACK資訊。 3) Does not return any HARQ-ACK information.
本發明實施例支援通過設計不同PUCCH資源單元組,有效解決UE和基地台不同距離對回饋資源的訴求不同的問題,提高了回饋HARQ-ACK的可靠度。同時,根據實際傳輸的回饋資訊位元,計算資源組中通道的資源需求RB數,有效節約了空口資源。 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.
下面從網路側設備和UE進行互動的角度,給出本發明實施例中網路側設備配置PUCCH資源及UE確定PUCCH資源可能的實施方式。 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.
實施方式1 Embodiment 1
本實施例中假設配置一個PUCCH資源單元組,PUCCH資源單元組中PUCCH資源的格式配置為PUCCH格式1,每個PUCCH上多工使用者可變(即根據實際回饋bit數調整每個PUCCH通道上的使用者多工數)。 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).
本實施例中HARQ編碼簿回饋過程具體如下: The HARQ codebook feedback process in this embodiment is as follows:
步驟1,UE接收基地台配置的一個或者多個PUCCH資源單元組,用於1組或者多組UE回饋HARQ-ACK編碼簿資訊;
基地台配置了1組上行PUCCH資源單元組-0,如表6所示,包含如下幾項內容:
如圖8所示為定義的一個PUCCH單元資源組示意圖,其M=4(4個PUCCH通道)。startRB=0(資源組的起始位置為RB0),每個PUCCH通道佔用1 RB,符號數為4。每個PUCCH資源上多工的使用者數:N=2或者N=4。其中:回饋HARQ-ACK編碼簿資訊為1bit時,多工4個UE,對應4個UE的初始迴圈位移索引為{0,3,6,9}。初始迴圈位移索引(initial cyclic shift indexes),為在同一個PUCCH通道上區分使用者所使用的參數,可以和3GPP NR中的定義保持一致。 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.
回饋HARQ-ACK編碼簿資訊為2bit時,多工2個使用者,對應2個UE的初始迴圈位移索引為{0,6}。 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}.
這裡需要說明以下兩點:初始迴圈位移索引數值可以為其它數值(如通過不同的正交序列索引(Orthogonal sequences index)得到),配置參數可以不是{0,6}或者{0,3,6,9},只要能夠區分不同UE即可。 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.
上述配置資訊可以通過專用信令(如RRC消息)配置,也可以通過公共信令配置,如通過BCCH(Broadcast Control Channel,廣播控制通道),或者MCCH(Multicast Control Channel)組播通道配置。 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.
步驟2,UE接收基地台發送的廣播組播服務組配置資訊,主要包括以下過程。 Step 2: The UE receives the broadcast multicast service group configuration information sent by the base station, which mainly includes the following processes.
A,基地台發送廣播組播服務組的RNTI配置資訊。 A. The base station sends the RNTI configuration information of the broadcast multicast service group.
上述RNTI配置資訊包括用於檢測控制通道的G-RNTI-DCI,及用於接收廣播組播服務PDSCH的G-RNTI-PDSCH,UE用G-RNTI-DCI作為擾碼來檢測控制通道,使用G-RNTI-PDSCH作為參數生成服務通道的擾碼序列。 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和G-RNTI-PDSCH可以相同(即同一個參數),也可以不同。這裡假設在基地台的覆蓋社區內,所有UE和基地台的距離相當或者基地台不進行區分,只用一個DCI進行調度PDSCH,此時G-RNTI-DCI和G-RNTI-PDSCH是同一個參數。 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,基地台發送UE在對應的PUCCH資源單元組的組編號資訊。 B. The base station sends the group number information of the UE in the corresponding PUCCH resource unit group.
本實施例中一個廣播組播服務組的UE被分配在一個PUCCH資源單元組,組編號可從0開始,如UE0的組編號是0,UE1的組編號是1,以此類推。 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.
步驟3,UE接收調度信令,計算HARQ-ACK的回饋位元數。 Step 3: The UE receives the scheduling signaling and calculates the number of feedback bits of HARQ-ACK.
調度信令是基地台發送的廣播組播服務調度信令,基於現有標準協定,確定UE需要回饋的廣播組播的HARQ-ACK位元數,支援現有NR協定中的半靜態編碼簿和動態編碼簿、以及增強型動態編碼簿,或其他類型的編碼簿。 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.
廣播組播的調度信令的內容參見上述描述,這裡不再重述,本實施例假設K=1,即只配置了一個PUCCH資源單元組-0,即Y=0位元,因此不需要在調度信令中攜帶PUCCH資源單元組指示。 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.
經過計算需要回饋的位元數為:OACK,假設有兩種情況:OACK=1,OACK=2。 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.
步驟4,根據UE對應的PUCCH資源單元組,UE的組編號(i),HARQ-ACK回饋的位元數,確定待回饋的HARQ-ACK編碼簿的PUCCH資源。 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.
依據調度信令接收PDSCH並進行在指定的PUCCH資源上回饋HARQ-ACK。 Receive PDSCH according to the scheduling signaling and feed back HARQ-ACK on the designated PUCCH resource.
本實施中UE的組編號(i),可以通過高層消息配置,具體的由基地台發送編號資訊給UE,假設共有user_number=8個使用者,UE0對應組編號0,UE1對應組編號1...UE7對應組編號7。 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.
計算回饋HARQ-ACK需要的PUCCH參數,主要包括:每個PUCCH佔用的RB數,需要PUCCH的數量,UE所在PUCCH資源的頻域起始位置RB_start1和初始迴圈位移索引指示。具體計算過程為:計算回饋的HARQ-ACK編碼簿需要的頻域RB數X1:由於PUCCH格式1的RB配置為1,因此無法再進行縮減,實際PUCCH的RB為1,即X1=1;計算總共需要PUCCH的通道數量:;計算UE所在PUCCH資源的頻域起始位置:;計算UE所在PUCCH的初始迴圈位移索引指示:index=i mod N;公式,表示向上取整的含義,表示向下取整的含義,/表示相除,mod表示求餘。 The PUCCH parameters required to calculate feedback HARQ-ACK mainly include: the number of RBs occupied by each PUCCH, the number of required PUCCHs, the frequency domain starting position RB_start1 of the PUCCH resource where the UE is located and the initial loop displacement index indication. The specific calculation process is: Calculate the frequency domain RB number The total number of channels requiring PUCCH: ;Calculate the frequency domain starting position of the PUCCH resource where the UE is located: ; Calculate the initial loop displacement index indication of the PUCCH where the UE is located: index=i mod N; Formula , indicating the meaning of rounding up, It means rounding down, / means division, and mod means finding the remainder.
假設user_number=8,OACK=1,N=4,資源配置如圖9所示:M1=8/4=2;;計算後得到UE(0)=0,UE(1)=0,UE(2)=0,UE(3)=0,UE(4)=1,UE(5)=1,UE(6)=1,UE(7)=1。 Assume user_number=8, O ACK =1, N=4, the resource configuration is as shown in Figure 9: M1=8/4=2; ;After calculation, we get UE(0)=0,UE(1)=0,UE(2)=0,UE(3)=0,UE(4)=1,UE(5)=1,UE(6) =1,UE(7)=1.
初始迴圈位移索引指示Index=i mod 4;即:UE(0)=0,UE(1)=1,UE(2)=2,UE(3)=3,UE(4)=0,UE(5)=1,UE(6)=2,UE(7)=3,這裡索引對應步驟1中{0,3,6,9}。 The initial loop displacement index indicates Index=i mod 4; that is: UE(0)=0, UE(1)=1, UE(2)=2, UE(3)=3, UE(4)=0, UE (5)=1, UE(6)=2, UE(7)=3, where the index corresponds to {0,3,6,9} in step 1.
如:user_number=8,OACK=2,N=2,資源配置如圖10所示:M1=8/2=4;;UE(0)=0,UE(1)=0,UE(2)=1,UE(3)=1,UE(4)=2,UE(5)=2,UE(6)=3,UE(7)=3。 For example: user_number=8, O ACK =2, N=2, the resource configuration is shown in Figure 10: M1=8/2=4; ;UE(0)=0,UE(1)=0,UE(2)=1,UE(3)=1,UE(4)=2,UE(5)=2,UE(6)=3, UE(7)=3.
初始迴圈位移索引指示Index=i mod 2;計算後得到UE(0)=0,UE(1)=1,UE(2)=0,UE(3)=1,UE(4)=0,UE(5)=1,UE(6)=0,UE(7)=1,這裡索引對應步驟1中{0,6}。 The initial loop displacement index indicates Index=i mod 2; after calculation, UE(0)=0, UE(1)=1, UE(2)=0, UE(3)=1, UE(4)=0, UE(5)=1, UE(6)=0, UE(7)=1, the index here corresponds to {0,6} in step 1.
本實施例配置了一個PUCCH資源單元組-0,因此PUCCH資源單元組指示bit數為0,同時,為了基地台調度靈活性,可以配置K個PUCCH資源單元組-0,則PUCCH資源單元組指示所需要的bit數為log2(K),並取整數的上限數值,K為大於1的正整數。 This embodiment configures one PUCCH resource unit group-0, so the number of PUCCH resource unit group indication bits is 0. 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.
實施方式2 Embodiment 2
本實施例中採用多DCI調度的方法,每個DCI針對一組近似距離的一組UE,網路側設備配置多個PUCCH資源單元組,不同廣播組播服務組對應的UE距離網路側設備的距離不同,或者路徑損耗不同,一組PUCCH資源單元組對應UE距離網路側設備的距離差值在設定範圍內容,或者路徑損耗差值在設定範圍內。上述網路側設備為基地台,UE進行編碼簿回饋過程如下該。 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.
步驟1,UE接收基地台配置的一個或者多個PUCCH資源單元組,用於1組或者多組UE回饋行HARQ-ACK編碼簿資訊。 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.
以基地台配置2個PUCCH資源單元組為例,不同資源單元組對應的UE組距離基地台的距離不同,或者到基地台的路徑損耗不同。 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.
基地台配置的PUCCH資源單元組-0參數如表7所示:
採用格式2的PUCCH的參數配置如表8所示:
基地台配置的PUCCH資源單元組-1參數如表9所示:表9 PUCCH資源單元組-1的配置資訊
採用格式3的PUCCH的參數配置,如表10所示:
如圖11所示為本實施例配置的2個PUCCH資源單元組示意圖,需要說明的是,這個2個PUCCH資源單元組,可以是在一個時槽中,也可以在 不同的時槽中,這裡不做限制。另外:為了簡化終端和基地台的實現,PUCCH單元資源組內的PUCCH通道格式相同。 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.
當以廣播的方式指示給UE時,可以將2個以上的PUCCH單元資源組配置資訊承載在BCCH或者MCCH上指示給UE。 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.
步驟2,UE接收基地台發送的廣播組播服務組配置資訊。 Step 2: The UE receives the broadcast multicast service group configuration information sent by the base station.
A.基地台發送給特定廣播組播服務分配的RNTI,具體參見實施方式1的說明,這裡的G-RNTI-DCI和G-RNTI-PDSCH可以是相同(即同一個參數),也可以不同。 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.
當通過廣播的方式將上述廣播組播服務組配置資訊指示UE時,廣播資訊中可指示多個不同G-RNTI-DCI(如:G-RNTI-DCI-1,G-RNTI-DCI-2,G-RNTI-DCI-3),同時還需要通過專用信令指示UE進行通道檢測時使用的哪一個G-RNTI-DCI。 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.
當通過專用信令將上述廣播組播服務組配置資訊指示UE時,專用信令指示一個G-RNTI-DCI(如:G-RNTI-DCI-1,或G-RNTI-DCI-2,或G-RNTI-DCI-3),以及一個G-RNTI-PDSCH。 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.基地台發送UE在對應的PUCCH資源單元組的組編號資訊。 B. The base station sends the group number information of the UE in the corresponding PUCCH resource unit group.
本實施例中一個廣播組播服務組中UE使用多組PUCCH資源單元組,可以將UE在廣播組播服務組中的編號,對應分配到PUCCH資源單元組,並確定UE在對應PUCCH資源單元中的組編號。編號(i)可從0開始,如UE0的編號是0,UE1的編號是1,以此類推。 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.
如共12個UE對某一特定的廣播組播服務感興趣,經過和基地台互動及配置資訊後,可生成如表11的內容。 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.
通過上述配置,不同DCI調度不同廣播組播服務組內UE,具體根據DCI調度不同廣播組播服務組內UE的調度及HARQ回饋PUCCH資源位置示意如圖12所示。 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.
步驟3,UE接收調度信令,計算HARQ-ACK的回饋位元數。 Step 3: The UE receives the scheduling signaling and calculates the number of feedback bits of HARQ-ACK.
調度信令是基地台發送的廣播組播服務調度信令,基於現有標準協定,確定UE需要回饋的廣播組播的HARQ-ACK位元數,支援現有NR協定中的半靜態編碼簿和動態編碼簿、以及增強型動態編碼簿,或其他類型的編碼簿。假設經過計算需要回饋的位元數為:OACK,假設需要回饋的位元數為:OACK=5。 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.
步驟4,根據UE對應的PUCCH資源單元組,組編號(i),HARQ-ACK回饋的位元數,確定待回饋的HARQ-ACK編碼簿的PUCCH資源。 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.
在接收調度信令前,基地台專用信令(如通過DCCH)指示UE所在PUCCH資源單元組及編號(i),這裡假設總共有user_number=6個使用者,UE0對應編號0,UE1對應編號1...UE5對應編號5。 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.
UE接收基地台發送的調度信令(假設以G-RNTI-DCI-1檢測得到的控制信令),依據調度信令接收PDSCH並進行在指定的PUCCH資源上回饋HARQ-ACK。 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.
調度信令內容參見上述實施方式的描述,這裡不再重述,需要說明的是,由於在專用信令中已經配置了PUCCH資源單元組,本實施例中調度信令中PUCCH資源單元組指示為0位元。 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.
計算回饋HARQ-ACK需要的PUCCH參數,包括:每個PUCCH佔用的RB數,需要PUCCH的數量,UE所在PUCCH資源的頻域起始位置RB_start1。 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.
所需相關參數包括:步驟1中配置的PUCCH資源單元組(每個PUCCH通道的RB數:X=2,包含PUCCH個數:M=3,多工的使用者數N=1);步驟2中的HARQ-ACK位元數OACK假設為5;計算每個PUCCH需要的頻域RB數X1:UE根據OACK和配置的調製階數和碼率等,選擇合適的RB數X1,這裡的合適RB數X1是指,通道RB數為X1時,能夠承載OACK個回饋位元,當通道RB數為(X1-1)時,就不能承載OACK個回饋位元。 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.
假設經計算需要RB數X1=1 RB。 Assume that the number of RBs required after calculation is X1=1 RB.

假設使用者數user_number=6,N=1,根據RB_strat1=i*1RB+RB_start得到:UE(0)=0,UE(1)=1,UE(2)=2,UE(3)=3,UE(4)=4,UE(5)=5。 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.
具體的PUCCH資源佔用示意圖如圖7所示。 The specific PUCCH resource occupation diagram is shown in Figure 7.
進一步的,DCI-RNTI-1對應配置的PUCCH資源單元組-0,DCI-RNTI-2對應配置的PUCCH資源單元組-1,因此調度信令中的資源單元組指示bit數為0,同時,為了基地台調度靈活性,可以配置K個PUCCH資源單元組-0作為第一資源單元組集合或者K個PUCCH資源單元組-1作為第二資源單元組集合,PUCCH資源單元組指示所需要的bit數為log2(K),並取整數的上限數值,這樣UE通過DCI-RNTI-1檢測的PDCCH,只去索引對應配置的PUCCH資源單元組。 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.
進一步地,為了滿足指示更大HARQA-ACK回饋位元數OACK,基地台可以配置不同的PUCCH資源單元在集合,每個集合對應不同的回饋位元數OACK,每個資源單元集合包含一個或者多個PUCCH資源單元組,範例如後。 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.
PUCCH資源單元組集合(0):包含4個PUCCH資源單元組(PUCCH資源單元組-0,PUCCH資源單元組-1,PUCCH資源單元組-2,PUCCH資源單元組-3),支援回饋位元0<OACK 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.
PUCCH資源單元組集合(1):包含4個PUCCH資源單元組(PUCCH資源單元組-0,PUCCH資源單元組-1,PUCCH資源單元組-2,PUCCH資源單元組-3),支援回饋位元2<OACK 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.
實施方式3 Embodiment 3
本實施例中配置多個PUCCH資源單元組,對應的多個UE組中UE與基地台的距離不同或路徑損耗不同,具體HARQ-ACK過程如下: 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:
步驟1,UE接收基地台配置的一個或者多個PUCCH資源單元組,用於1組或者多組UE回饋行HARQ-ACK資訊;基地台配置2個或者多個PUCCH資源單元組,每個資源單元組對應不同的UE,如表12所示,基地台配置的PUCCH資源單元組-0參數如下:
上述採用格式2的PUCCH的參數配置如表13所示:
另外,為了進一步增加回饋通道調度的靈活性,增加指示pucch_slot_offset,該數值表示相對於調度信令中「HARQ回饋時間指示」表示的時槽的偏移量。如:UE接收到廣播組播的PDSCH是在時槽n,調度信令中HARQ回饋時間指示資訊為k1,在UE在該PUCCH上回饋HARQ-ACK的時槽為:n+k1+pucch_slot_offset。在預設不配置的情況下,pucch_slot_offset=0。 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可以在調度信令中指示,也可以在高層信令中指示。本實施例假設在高層信令中指示,且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.
基地台配置的PUCCH資源單元組-1參數如表14所示:
上述採用格式3的PUCCH參數配置如表15所示:
另外,為了進一步增加回饋通道調度的靈活性,進一步指示pucch_slot_offset,該數值表示相對於調度信令中「HARQ回饋時間指示」表示 的時槽的偏移量。如:UE接收到廣播組播的PDSCH是在時槽n,調度信令中「HARQ回饋時間指示」資訊為k1,在UE在該PUCCH上回饋HARQ-ACK的時槽為:n+k1+pucch_slot_offset。在預設不配置的情況下,pucch_slot_offset=0。 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可以在調度信令中指示,也可以在高層信令中指示。本實施例假設在高層信令中指示,且pucch_slot_offset=1。 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.
如圖11所示為本實施例配置的2個PUCCH資源單元組示意圖。 Figure 11 shows a schematic diagram of two PUCCH resource unit groups configured in this embodiment.
以廣播的方式指示上述配置資訊時,可以將2個以上的PUCCH單元資源組配置資訊,承載在BCCH或者MCCH上指示給UE。 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.
步驟2,UE接收基地台發送的廣播組播服務組配置資訊。 Step 2: The UE receives the broadcast multicast service group configuration information sent by the base station.
A,基地台發送廣播組播服務組的RNTI配置資訊。 A. The base station sends the RNTI configuration information of the broadcast multicast service group.
RNTI配置資訊的內容參見實施方式1的描述,這裡不再重述,本實施方式使用一個調度信令調度PDSCH(即使用一個G-RNTI-DCI),對於UE使用的PUCCH資源單元組及UE在廣播服務組內的編號通過專用信令發送。因此本實施的G-RNTI-DCI和G-RNTI-PDSCH是相同的。 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:基地台發送UE在對應的PUCCH資源單元內的組編號資訊。 B: The base station sends the group number information of the UE in the corresponding PUCCH resource unit.
為了更好的適應終端位置的變化,及時有效的調整UE對應的PUCCH資源單元組,本實施例分成兩個步驟指示:Step 1,指示UE所在廣播組播服務組的編號(k),編號可從0開始,如UE0的編號是0,UE1的編號是1,UE2的編號是2,UEx的編號是X;Step 2,指示廣播組播服務組內UE對應的PUCCH資源單元組資訊,從而使UE結合上述編號和對應的PUCCH資源單元資訊,得到UE在對應PUCCH資源單元組內的組編號,具體指示方式如下: 在一個廣播組播服務組對應多個PUCCH資源單元組時,接收網路側設備發送的指示廣播組播服務組各UE順序的編號及各UE對應的PUCCH資源單元組的點陣圖,根據屬於同一PUCCH資源單元組的UE在該點陣圖中的編號順序,確定該UE的組編號。 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.
當PUCCH資源單元組分為2個組時,PUCCH資源單元組點陣圖為[X]bit,X是step1步驟中的UE數,每個點陣圖指示數值為0或者1。0表示對應UE在PUCCH資源單元組0,1表示對應UE在PUCCH資源單元組1,或者相反。同時每個UE在PUCCH資源單元組內的編號,按照點陣圖指示的順序進行遞增。 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.
如圖13所示為兩個PUCCH資源單元組點陣圖,其中有6個UE在某個廣播組播服務組中,UE0,UE1,UE2...UE5。 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.
Step1中,UE在廣播組播服務組的編號(k)為:UE0=0,UE1=1,UE2=2,UE3=3,UE4=4,UE5=5。 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.
Step 2中,點陣圖指示為001101,0表示對應編號k的UE配置為PUCCH資源單元組-0,1表示對應編號k的UE配置為PUCCH資源單元組-1,相應UE在對應的PUCCH資源單元組的組編號(i)為: 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資源單元組-0:UE0,UE1,UE4,在對應的PUCCH資源單元組內的組編號為:0,1,2。 PUCCH resource unit group-0: UE0, UE1, UE4. The group numbers in the corresponding PUCCH resource unit group are: 0, 1, 2.
PUCCH資源單元組-1:UE2,UE3,UE5,在對應的PUCCH資源單元組內的組編號為: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.
上述步驟中,step1可以採用高層信令的方法進行半靜態配置,更新間隔週期較長。Step2可以採用實體層指示或者高層信令指示,更新間隔週期較短,以適應UE和基地台距離變化以及回饋通道品質的變化。 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.
步驟3,UE接收調度信令,計算HARQ-ACK的回饋位元數。 Step 3: The UE receives the scheduling signaling and calculates the number of feedback bits of HARQ-ACK.
調度信令是基地台發送的廣播組播服務調度信令,基於現有標準協定,確定UE需要回饋的廣播組播的HARQ-ACK位元數,支援現有NR協定中的半靜態編碼簿和動態編碼簿、以及增強型動態編碼簿,或其他類型的編碼簿。假設經過計算需要回饋的位元元元數為:OACK。 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 .
步驟4,根據配置的PUCCH資源單元組,所在組編號(i),HARQ-ACK回饋的位元數,確定待回饋的HARQ-ACK編碼簿的PUCCH資源,和回饋時槽。 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.
UE接收基地台發送廣播組播調度信令的內容參見上述示例的描述,這裡不再重述,依據調度信令進行廣播組播資料接收並確定需回饋的HARQ-ACK編碼簿,並進行如下計算: 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:計算回饋PUCCH的時槽位置;所需的參數為步驟1中配置的每個PUCCH資源單元組的pucch_slot_offset。(資源單元組-0 pucch_slot_offset=0,資源單元組-1 pucch_slot_offset=1。)。 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.).
調度信令中的HARQ回饋時間指示,假設k1=3。 HARQ feedback time indication in scheduling signaling, assuming k1=3.
接收PDSCH對應的上行時槽位置:假設為slot n。 The uplink slot position corresponding to the received PDSCH: assumed to be slot n.
步驟2中的分組資訊:PUCCH資源單元組-0:UE0,UE1,UE4,在對應的PUCCH資源單元組內的組編號為:0,1,2; PUCCH資源單元組-1:UE2,UE3,UE5,在對應的PUCCH資源單元組內的編號為:0,1,2。 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.
回饋PUCCH的時槽位置為:slot n+k1+pucch_slot_offset。即PDSCH接收對應的上行時槽加上k1再加上偏移量,本示例的回饋時槽位置如圖14所示,PUCCH資源單元組-1中UE的PUCCH時槽位置向後偏移了1個時槽。 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:回饋HARQ-ACK需要的PUCCH參數;回饋HARQ-ACK需要的PUCCH參數,包括:每個PUCCH佔用的RB數,需要PUCCH的數量,UE所在PUCCH資源的頻域起始位置RB_start1。 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.
這裡以PUCCH資源單元組-1為例,PUCCH資源單元組-0的計算方法相同,不再重述。 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.
計算上述PUCCH需要的相關參數:步驟1中配置的PUCCH資源單元組(每個PUCCH通道的RB數:X=2,包含PUCCH個數:M=3,多工的使用者數N=1);步驟2中的HARQ-ACK位元數OACK假設為5;計算每個PUCCH需要的頻域RB數X1:UE根據OACK和配置的調製階數,碼率等,選擇合適的RB數X1。這裡的合適RB數X1是指,通道RB數為X1時,能夠承載OACK個回饋位元;當通道RB數為(X1-1)時,就不能承載OACK個回饋位元。 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.
假設經計算需要RB數X1=1 RB。 Assume that the number of RBs required after calculation is X1=1 RB.
計算UE所在PUCCH資源的頻域起始位置:。 Calculate the frequency domain starting position of the PUCCH resource where the UE is located: .
表示向下取整,「/」表示相除。 means rounding down, "/" means division.
如:user_number=6,N=1,UE佔用的PUCCH資源示意圖如圖7所示。 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。 RB_strat1=i*1RB+RB_start.
計算得到UE(0)=0,UE(1)=1,UE(2)=2,UE(3)=3,UE(4)=4,UE(5)=5。 The calculation results are UE(0)=0, UE(1)=1, UE(2)=2, UE(3)=3, UE(4)=4, UE(5)=5.
本實施例技術方案補充說明:本實施例配置了一個「PUCCH資源單元組-0」和一個「PUCCH資源單元組-1」,如果通過廣播組播配置資訊進行指示,則調度信令中的PUCCH資源單元組指示的bit數為0,同時,為了基地台調度靈活性,基地台還可以配置多個「PUCCH資源單元組-0」,如配置了K個「PUCCH資源單元組-0」和K個「PUCCH資源單元組-1」,則調度信令總的PUCCH資源單元組指示所需要的bit數為log2(M),並取整數的上限數值。 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.
為了滿足指示更大HARQA-ACK回饋位元元數OACK,基地台可以配置不同的PUCCH資源單元在集合。每個集合對應不同的回饋位元數OACK,每個資源單元集合包含一個或者多個PUCCH資源單元組。例如:PUCCH資源單元組集合(0):包含4個PUCCH資源單元組(PUCCH資源單元組-0,PUCCH資源單元組-1,PUCCH資源單元組-2,PUCCH資源單元組-3),支援回饋位元0<OACK 2;PUCCH資源單元組集合(1):包含4個PUCCH資源單元組(PUCCH資源單元組-0,PUCCH資源單元組-1,PUCCH資源單元組-2,PUCCH資源單元組-3),支援回饋位元2<OACK 16; 當UE回饋HARQ-ACK時,根據回饋位元OACK,選擇資源單元集合。如小於等於2bit選擇集合(0),大於2bit選擇集合(1)。然後根據PUCCH資源單元組指示選擇資源單元組。 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 the set. Each set corresponds to a different number of feedback bits O ACK , and each resource unit set contains one or more PUCCH resource unit groups. For example: PUCCH resource unit group set (0): contains 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), and supports feedback Bit 0<O ACK 2; 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), supports feedback Bit 2<O ACK 16; When the UE feeds back HARQ-ACK, select the resource unit set according to the feedback bit O ACK . If it is less than or equal to 2bit, select the set (0), and if it is greater than 2bit, select the set (1). Then select a resource unit group according to the PUCCH resource unit group indication.
