Description

混合自动重传请求应答码本确定方法、装置及其设备 技术领域
本申请涉及通信技术领域，尤其涉及一种码本反馈的技术领域。
背景技术
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。
NR(New Radio，新无线)的免授权频谱系统引入的一种新的HARQ(Hybrid Automatic Repeat-reQuest，混合自动重传请求)反馈方式为One-Shot(单次)HARQ反馈。网络设备可以通过DCI(Downlink Control Information，下行控制信息)信息触发UE(User Equipment，用户设备)进行One-Shot HARQ反馈，即，反馈一个Type3码本给网络设备。其中，Type3码本可以包括两种类型：类型1是携带NDI(New Data Indicator，新数据指示符)的One-Shot HARQ反馈；类型2是不携带NDI的One-Shot HARQ反馈。网络设备可以通过RRC(Radio Resource Control，无线资源控制)信令对UE进行配置，使得UE在进行HARQ反馈时携带NDI信息，或不携带NDI信息。
但是，在现有技术中，当用户设备反馈不携带NDI信息的One-Shot HARQ反馈时，Type-3 HARQ-ACK码本的重置过程会导致用户设备不能正确传输HARQ-ACK信息。

步骤S220，所述用户确定Type-3 HARQ-ACK码本；具体的，所述用户设备根据目标混合自动重传请求HARQ进程中的目标传输块TB对应的数据调度信息，确定Type-3 HARQ-ACK码本中的所述目标HARQ进程中的所述目标TB的HARQ-ACK信息；其中，所述Type-3 HARQ-ACK码本包括一个物理上行控制信道PUCCH组中所有配置的载波上的所有HARQ进程对应的HARQ-ACK信息；
步骤S230，所述网络设备接收所述用户设备反馈的所述Type-3 HARQ-ACK码本。其中，Type3码本包括两种类型：类型1是携带NDI(New Data Indicator，新数据指示符)的One-Shot HARQ反馈；类型2是不携带NDI的One-Shot HARQ反馈。网络设备可以通过RRC(Radio Resource Control，无线资源控制)信令对UE(User Equipment，用户设备)进行配置，使得UE在进行HARQ反馈时携带NDI信息，或者不携带NDI信息。
类型1：携带NDI的One-Shot HARQ反馈
1)用户设备反馈最近一次收到的HARQ进程号对应的NDI信息和HARQ-ACK信息。
2)如果某个HARQ进程没有先验NDI信息，用户设备假设NDI取值为0。
3)每个TB对应一个NDI值。
类型2：不携带NDI的One-Shot HARQ反馈
1)用户设备反馈HARQ进程号对应的HARQ-ACK信息且不反馈对应的NDI信息。
2)对于某一个HARQ进程，如果用户设备进行过一次ACK反馈后，应对该HARQ进程进行状态重置。
所述数据调度信息可用于指示所述目标TB当前被调度新传、重传还是未被调度。
所述HARK-ACK信息包括ACK信息或NACK信息。
可选的，所述目标TB对应的数据调度信息包括第一信息、第二信息和第三信息中的一种。其中：
所述第一信息包括：所述目标TB当前被调度新传的信息；
所述第二信息包括：所述目标TB当前被调度重传的信息；
所述第三信息包括：所述目标TB当前未被调度的信息。
可选的，所述目标TB当前被调度新传的信息包括：所述目标TB当前的NDI信息相对于上一次的NDI信息取值不同，或所述目标TB为半持续调度SPS PDSCH中的TB。
可选的，所述目标TB当前被调度重传的信息包括：所述目标TB当前的NDI信息相对于上一次的NDI信息取值相同，或所述目标TB为SPS PDSCH中的TB且NDI信息取值为1。

可选地，所述目标TB当前不对应DCI信息，包括：所述目标TB当前没有被DCI指示NDI信息。
具体而言，对于有PDCCH调度的数据传输，DCI中包括NDI域，或者说，每个TB对应一个NDI信息。对于被调度的某个HARQ进程中的某个TB标号，如果终端设备收到的该TB标号对应的NDI信息相对于上一次该终端设备收到该TB标号对应的NDI信息翻转，说明该终端设备当前收到的该TB是一个新传；如果终端设备收到该TB标号的NDI信息相对于上一次该终端设备收到该TB标号对应的NDI信息未翻转，说明该终端设备当前收到的该TB是一个重传。
对于没有PDCCH调度的数据传输，如SPS(Semi-Persistent Scheduling，半持续性调度)配置资源上的传输，下行SPS配置资源上传输的SPS PDSCH只包括初传。若某个HARQ进程初传失败需要重传，网络设备会通过CS-RNTI(Configured Scheduling Radio Network Temporary Identifier，配置的无线网络临时标识)扰码的DCI来调度相同的HARQ进程，并将NDI域设置为“1”。即，如果终端设备收到CS-RNTI扰码的DCI且NDI域设置为“1”，终端设备会认为该DCI调度的HARQ进程为重传。或者说，该HARQ进程中传输的NDI域设置为“1”的TB为SPS PDSCH中的TB。

请参见图3，现有技术中，对于不包括NDI的Type-3 HARQ-ACK码本，在按CBG的反馈的过程中，针对目标HARQ进程中的目标TB，若UE之前已经上报了ACK，那么UE将对应的HARQ-ACK信息比特置为NACK；否则，UE将反馈对应的HARQ-ACK信息。在该过程中可能会出现的问题是，当同一个HARQ进程在两次Type-3 HARQ-ACK码本反馈过程中均被调度且对应的译码信息均为ACK的情况下，第二次Type-3 HARQ-ACK码本中则不包括该HARQ进程第二次被调度时得到的ACK信息，而是在上一次调度中反馈了ACK信息后被设置为NACK的HARQ-ACK信息。由此导致Type-3 HARQ-ACK码本反馈不正确。
同样的，对于不包括NDI的Type-3 HARQ-ACK码本，在按TB的反馈的过程中，针对目标HARQ进程中的目标TB，如果UE之前已经上报了NACK，那么UE将反馈对应的HARQ-ACK信息；否则，UE将对应的HARQ-ACK信息比特置为NACK。在该过程中可能会出现的问题是，当同一个HARQ进程在两次Type-3 HARQ-ACK码本反馈过程中均被调度且第一次的译码信息为ACK的情况下，第二次Type-3 HARQ-ACK码本中则不包括该HARQ进程第二次被调度时得到的ACK信息，而是在上一次调度中反馈了ACK信息后被设置为NACK的HARQ-ACK信息。由此导致Type-3 HARQ-ACK码本反馈不正确。
本申请的实施方式一，如图4所示，在针对每个TB的HARQ-ACK信息比特反馈时，根据目标HARQ进程中的目标TB对应的数据调度信息，来确定反馈的Type-3HARQ-ACK码本所包含的HARQ-ACK信息。而不是，用户终端已上报ACK了，就直接将所述HARQ-ACK信息设置为NACK。由此，保证使Type-3 HARQ-ACK码本正确重置或生成。
