Description

一种反馈信息长度的确定方法及装置、通信设备 技术领域
本申请实施例涉及移动通信技术领域，具体涉及一种反馈信息长度的确定方法及装置、通信设备。
背景技术
随着无线通信技术的发展，长期演进(LTE，Long Term Evolution)系统和新空口(NR，New Radio)系统都会考虑在免授权频谱上布网，以利用免授权频谱来进行数据业务的传输。
为了降低先听后说(LBT，Listen Before Talk)的使用，发送端一旦抢占信道成功应该尽可能占用连续的资源进行数据传输。另一方面，接收端应该尽可能的将反馈信息(即ACK/NACK信息)复用传输，即占用少量的时域资源，避免不必要的LBT过程。当接收端将多个数据信道对应的反馈信息通过复用的方式反馈给发送端时，如何高效的确定反馈信息的比特长度是一个需要解决的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global  System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
示例性的，本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用 户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
可选地，终端设备120之间可以进行终端直连(Device to Device，D2D)通信。
可选地，5G系统或5G网络还可以称为新无线(New Radio，NR)系统或NR网络。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
为便于理解本申请实施例的技术方案，以下对本申请实施例涉及到的相关技术进行说明。
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如，在一些地区，通信设备遵循“先听后说”原则， 即通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。
LTE系统和NR系统都会考虑在免授权频谱上布网，以利用免授权频谱来进行数据业务的传输。在NR系统应用到免授权频谱(简称为NR-U)上时，同样需要遵循LBT原则，本申请实施例的技术方案可以但不局限于应用于NR-U系统中，例如也可以应用于LTE-U系统中。此外，本申请实施例的技术方案适用于上行ACK/NACK传输也适用于下行ACK/NACK传输。
图2为本申请实施例提供的反馈信息长度的确定方法的流程示意图，如图2所示，所述反馈信息长度的确定方法包括以下步骤：
步骤201：第一节点根据HARQ进程数信息和传输资源的信息，确定反馈信息的比特数量。
本申请实施例中，所述第一节点确定出反馈信息的比特数量后，基于所确定的反馈信息的比特数量，向第二节点发送反馈信息。
这里，第一节点和第二节点可以有如下两种实现方式：
1)所述第一节点为终端，所述第二节点为基站；或者，
2)所述第一节点为基站，所述第二节点为终端。
这里，终端可以是手机、平板电脑、车载终端、笔记本等任意能够与网络进行通信的设备。基站的类型不受限制，例如5G中的gNB。
本申请实施例中，第一节点是指数据接收端，也即反馈信息的发送端。对应地，第二节点是指数据发送端，也即反馈信息的接收端。
本申请实施例的技术方案适用于上行ACK/NACK传输也适用于下行ACK/NACK传输。例如：基站向UE发送下行数据后，UE需要向基站进行上行的HARQ-ACK反馈。再例如：UE向基站发送上行数据后，基站需要向UE进行下行的HARQ-ACK反馈。
本申请实施例中，所述HARQ进程数信息包括：
1)所述第一节点支持的HARQ进程数的最大值；或者，
2)基站配置的HARQ进程数，其中，所述基站配置的HARQ进程数小于等于所述第一节点支持的HARQ进程数的最大值。
举个例子：所述第一节点支持的HARQ进程数的最大值为32，所述HARQ进程数信息可以是32，也可以是由基站配置的比32小的正整数。
本申请实施例中，所述传输资源是指能够用于承载目标数据的传输资源，所述第一节点传输所述目标数据的反馈信息。进一步，所述目标数据对应的反馈信息通过复用方式进行传输。
这里，所述目标数据对应的反馈信息通过复用方式进行传输，可以但不局限于通过时分复用的方式进行传输。
本申请实施例中，所述传输资源的信息可以为：
1)至少一个信道占用时间(COT，Channel Occupation Time)内的传输资源单元的数量，进一步，所述传输资源的信息包括：至少一个COT内的具有相同传输方向的传输资源单元的数量。或者，
2)第一时间与第二时间之间的全部传输资源单元的数量，进一步，所述传输资源的信息包括：第一时间与第二时间之间的具有相同传输方向的全部传输资源单元的数量。
这里，一个传输资源单元为一个时隙；或者，一个传输资源单元为一个载波内的一个时隙；或者，一个传输资源单元为一个带宽部分(BWP，Band Width Part)内的一个时隙。
需要说明的是，对于上行数据传输而言，所述传输资源单元为上行传输资源单元；对于下行数据传输而言，所述传输资源单元为下行传输资源单元。
上述方案中，第二节点(数据发送端)可以在所述第一时间与所述第二时间之间的全部传输资源单元上向第一节点发送目标数据，即：所述第一节点在所述第一时间与所述第二时间之间的全部传输资源单元上接收到目标数据；或者，第二节点(数据发送端)可以在所述第一时间与所述第二时间之间的部分传输资源单元上向第一节点发送目标数据，即：所述第一节点在所述第一时间与所述第二时间之间的部分传输资源单元上接收到目标数据。
再举个例子：第一节点为UE1，第二节点为基站，第一时间为t1，第二时间为t2，那么，基站在以t1为起始时间，以t2为结束时间之内10个时隙向多个终端发送下行数据，对于UE1来说只在其中的2个时隙中接收到数据，但是UE1认为对应的传输资源依然是10个时隙。
本申请实施例中，所述第一时间和/或所述第二时间，可以通过以下方式确定：
1)所述第一时间和/或所述第二时间为基站配置的；或者，
2)所述第一时间和/或所述第二时间基于处理时延确定。
进一步，所述第一时间根据所述第一节点前一次发送反馈信息的起始时间和所述处理时延确定，进一步，所述第一时间根据所述第一节点前一次发送反馈信息的起始时间减去所述处理时延得到的值确定，例如：所述第一时间小于等于所述第一节点前一次发送反馈信息的时间减去所述处理时延；和/或，所述第二时间根据所述第一节点本次发送反馈信息的起始时间和所述处理时延确定，进一步，所述第二时间根据所述第一节点本次发送反馈信息的起始时间减去所述处理时延得到的值确定，例如所述第二时间小于等于所述第一节点本次发送反馈信息的时间减去所述处理时延。参照图3，图3中示意出了两个COT，分别为COT1和COT2，COT1早于COT2，COT1内的UL对应的时间代表了第一节点前一次发送反馈信息的时间置N1，COT2内的PUCCH对应的时间代表了第一节点本次发送反馈信息的时间N2，假设第一节点的处理时延为X，那么，t1<N1+X，t2<N2+X。需要明确的是，t1到t2跨越了两个COT，第一节点在COT2内的PUCCH上发送的反馈信息是针对两部分的下行数据，参照图3中的COT1内大括号对应的DL部分和COT2内大括号对应的DL部分。
进一步，如果所述第一时间和所述第二时间所确定的时间段在时间上具有周期性，那么，所述第一节点前一次接收传输资源对应的第二时间为所述第一节点本次接收传输资源对应的第一时间。
本申请实施例中，所述第一节点根据HARQ进程数信息和传输资源的信息之间的最小值，确定反馈信息的比特数量。进一步，所述第一节点将所述HARQ进程数信息和传输资源的信息之间的最小值乘以第一系数，作为所述反馈信息的比特数量。这里，所述第一系数为常数；或者，所述第一系数为一个HARQ进程包括的最大传输块(TB，Transmission Block)数；或者；所述第一系数为一个HARQ进程包括的最大码块组(CBG，Code Block Group)数。
举个例子：假设HARQ进程数信息为N harq，传输资源的信息为N slot，那么，反馈信息的比特数量为C·min(N harq,N slot)，其中，C为第一系数。
进一步，如果所述HARQ进程数信息和传输资源的信息之间的最小值为所述传输资源信息，则所述反馈信息与所述传输资源的索引信息具有对应关系，其中，所述传输资源的索引信息包括时域索引信息和/或频域索引信息。
举个例子：传输资源对应10个slot{S1，S2，S3……，S10}，HARQ进程数为16，且为单TB传输。终端在S1和S2中接收到PDSCH，其他slot内未收到数据，则终端 得到10比特反馈信息，分别对应于10个slot，{b1，b2，NACK,NACK,……NACK}，其中b1和b2分别对应S1和S2中PDSCH的反馈信息(根据译码结果确定为ACK或NACK)，其他比特位使用NACK占位。
进一步，如果所述HARQ进程数信息和传输资源的信息之间的最小值为所述HARQ进程数信息，则所述反馈信息与所述HARQ进程的索引信息具有对应关系。
举个例子：传输资源对应10个slot{S1，S2，S3……，S10}，HARQ进程数为8，单TB传输。终端在S1中接收到PDSCH对应的HARQ进程号为4，在S3中接收到PDSCH对应的HARQ进程号为1，其他slot内未收到数据，则终端得到8比特反馈信息，分别对应于8个HARQ进程，{b S3，NACK,NACK,b S1,NACK,……NACK}，其中b S3为S3中PDSCH的反馈信息(根据译码结果确定为ACK或NACK)，b S1为S1中PDSCH的反馈信息，其他比特位使用NACK占位。
