技术领域
本公开实施例涉及无线通信技术领域,尤其涉及一种PUCCH的发送方法、接收方法、终端和网络侧设备。
背景技术
在对4G以后的下一代通信系统研究中,将系统支持的工作频段提升至6GHz以上,最高约达100GHz。高频段具有较为丰富的空闲频率资源,可以为数据传输提供更大的吞吐量。目前3GPP正在开展新空口(New Radio,NR)中高频段的研究和标准化工作,高频信号的波长短,同低频段相比,能够在同样大小的天线面板上布置更多的天线阵元,利用波束赋形技术形成指向性更强、波瓣更窄的波束。因此,将大规模天线和高频通信相结合,也是未来的趋势之一。
在高频段通信系统中,由于无线信号的波长较短,较容易发生信号传播被阻挡等情况,导致信号传播中断。如果采用相关技术中的无线链路重建,则耗时较长,因此引入了波束失败恢复机制。
对于多载波的场景(可以理解为载波聚合(CA),有多个载波(carrier),或多个成员载波(CC),或多个小区(cell)),其中,存在一个主小区(如主小区群(master cell group,MCG)中的主小区(Primary cell,PCell),或辅小区群(secondary cell group,SCG)中的主辅小区(Primary secondary cell,PSCell)),存在至少一个辅小区(Secondary cell,Scell)。
在相关技术中刚刚启动对多载波场景的波束失败恢复机制的研究。需要面临的问题是:当一个或多个小区发生波束失败事件,并且执行波束失败恢复过程时,怎样确定这些小区上物理上行控制信道(Physical Uplink Control  Channel,PUCCH)的波束信息。
发明内容
