Description
相关申请的交叉引用
本申请要求在2019年07月19日提交中国专利局、申请号为201910656646.8、申请名称为“信息传输方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信技术领域,尤其涉及信息传输方法及装置。
在NR(New Radio,新空口)***中,定义了NR物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)格式(format)0、1、2、3、4共5种PUCCH format,其中,format 0和1的PUCCH可以承载1~2比特UCI(Uplink Control Information,上行控制信息)传输,PUCCH format 2、3和4可以承载大于2比特UCI传输。混合自动重传请求应答(Hybrid Automatic Repeat Request-Acknowledge Character,HARQ-ACK)可以使用这5种PUCCH format中的任何一种。终端根据HARQ-ACK的比特数在预先配置给终端的多个PUCCH资源集合中选择一个,其中,每个PUCCH资源集合对应一个比特数范围。调度请求(Scheduling Request,SR)可以使用PUCCH format 0或1传输,所使用的PUCCH资源由高层信令配置。周期信道状态信息(Channel State Information,CSI)可以配置使用PUCCH format 2或3或4传输,所使用的PUCCH资源由高层信令配置。
在NR版本15(R15)***中,承载CSI/SR的PUCCH与一个承载HARQ-ACK的PUCCH发生资源重叠时,根据如下的方法进行复用传输:
当承载SR的PUCCH与承载HARQ-ACK的PUCCH格式0重叠时,通过HARQ-ACK的PUCCH资源复用传输SR和HARQ-ACK;
当承载SR的PUCCH格式0与承载HARQ-ACK的PUCCH格式1重叠时,丢弃SR;
当承载SR的PUCCH格式1与承载HARQ-ACK的PUCCH格式1重叠时,积极SR时HARQ-ACK放在SR的PUCCH资源上传输,消极SR时HARQ-ACK放在HARQ-ACK的PUCCH资源上传输;
当承载SR的PUCCH与承载HARQ-ACK的PUCCH格式2/3/4重叠时,SR(包括积极的和消极的SR)和HARQ-ACK都放在HARQ-ACK的资源上进行传输;
当承载SPS(Semi-Persistent Scheduling,半永久性调度/半静态调度)HARQ-ACK,即对应SPS PDSCH(Physical Downlink Shared Channel,物理下行链路共享信道)的HARQ-ACK的PUCCH与承载CSI的PUCCH重叠时,将SPS HARQ-ACK转移到CSI对应的PUCCH资源上与CSI复用传输。当承载动态的(dynamic)HARQ-ACK(即对应具有对应的DCI调度的PDSCH的HARQ-ACK)的PUCCH与承载CSI的PUCCH重叠时,根据HARQ-ACK和CSI的比特数,在配置的PUCCH资源集合中选择一个集合,再根据调度PDSCH的DCI中的PUCCH资源指示域从选择的一个集合中确定出一个PUCCH资源,用于同时承载HARQ-ACK和CSI。
综上所述,在现有技术中,只存在一个HARQ-ACK的PUCCH资源和CSI/SR的PUCCH资源重叠的情况,并不存在多个时分复用的用于承载HARQ-ACK的PUCCH和一个用于承载SR/CSI的PUCCH资源重叠的情况,在Rel-16(版本16)中将支持一个时隙中传输多个时分复用的用于承载HARQ-ACK的PUCCH,因此当多个承载HARQ-ACK的PUCCH资源和用于承载SR/CSI的PUCCH资源重叠时,目前还没有解决方案。
