Description

PUCCH传输功率的控制方法、装置及终端
交叉引用
本申请要求在2021年09月26日提交中国专利局、申请号为202111130451.3、名称为“PUCCH传输功率的控制方法、装置及终端”的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
技术领域
本申请属于无线通信技术领域,具体涉及一种物理上行控制信道(Physical Uplink Control Channel,PUCCH)的传输功率控制方法、装置及终端。
背景技术
在新空口(New Radio,NR)系统中,考虑到一个用户设备(User Equipment,UE)可能同时支持不同的业务,而不同的业务对应不同的业务需求,如时延、可靠性等方面。因此引入了标记物理上行控制信道(Physical Uplink Control Channel,PUCCH)和/或物理上行共享信道(Physical Uplink Shared Channel,PUSCH)优先级的机制。具体的引入了2级物理层优先级,即高优先级、低优先级。
上行控制信息(Uplink Control Information,UCI)在物理上行控制信道(PUCCH)上传输。由于起始符号和符号长度等原因,可能出现不同的PUCCH之间在时间上重叠。在不同优先级的PUCCH时域资源重叠时,简单的丢弃低优先级的PUCCH会对低优先级的业务传输产生较大的性能影响,因此为了降低对低优先级传传输的影响,要求通信系统支持不同优先级的PUCCH之间的复用,例如,当承载高优先级(High priority,HP)混合自动 重传请求应答(Hybrid automatic repeat request acknowledgement,HARQ-ACK)的PUCCH与承载低优先级(Low priority,LP)HARQ-ACK的PUCCH的时域资源重叠且满足一定条件时,用户设备(User Equipment,UE)将HP HARQ-ACK和LP HARQ-ACK复用在一个PUCCH上传输。由于HP HARQ-ACK和LP HARQ-ACK的可靠性要求不一样,因此需要对应不同的传输码率,即需要分别编码。同样,不同优先级的UCI复用也需要满足一定的时间线要求。
然而,在现有技术中只支持相同优先级间的信道复用,一个PUCCH资源上承载一个优先级的UCI。UE在进行PUCCH传输功率控制时需要根据单位资源单元比特数(Bit Pre Resource Element,BPRE)确定传输功率,UE根据要传输的UCI的比特数和资源单元(Resource Element,RE)数确定BPRE。现有技术中一个PUCCH只有一个BPR。当一个PUCCH资源上复用了不同优先级的UCI时(如LP HARQ-ACK,HP HARQ-ACK),一个PUCCH格式可以配置2个码率,一个是低优先级UCI的编码码率,一个是高优先级UCI的编码码率,在这种情况下,如何确定复用不同优先级的PUCCH的传输功率目前尚未给出有效的解决方案。
发明内容

在一个可能的实现方式中,在S220中,终端可以根据所述第一比特数,确定所述PUCCH的PUCCH传输功率调整因子,然后再根据所述PUCCH传输功率调整因子,确定所述PUCCH的传输功率。
例如,终端可以先确定PUCCH小区c(例如,主小区PCell,主辅小区PScell,PUCCH辅小区SCell等)的载波f的BWP b上的PUCCH传输功率调整因子Δ TF,b,f,c(i),然后根据PUCCH传输功率调整因子Δ TF,b,f,c(i),确定PUCCH的传输功率。
由于不同PUCCH格式的信道结构、能承载的UCI的比特数等不同,例如,PUCCH格式0和PUCCH格式1只能承载1或2比特的UCI,而PUCCH格式2、PUCCH格式3以及PUCCH格式4,承载大于2比特UCI。因此,在本申请实施例中,针对不同的PUCCH格式,提供不同的PUCCH传输功率调整因子的确定方法。
在一个可能的实现方式中,PUCCH的格式包括以下之一:PUCCH格式 2、PUCCH格式3、PUCCH格式4。
