Description

上行控制信道传输方法及终端和基站 技术领域
本申请涉及无线通信技术，特别涉及上行控制信道传输技术。
背景技术
目前的5G的NR(new radio)系统中支持两种时间长度的物理上行控制信道PUCCH，即短PUCCH(short-PUCCH)和长PUCCH(long-PUCCH)。其中，短PUCCH包括1或2个时域符号，长PUCCH包括4－14个时域符号。传输上行调度请求SR的上行控制信道参数通常是半静态配置的(例如：周期、偏移、PUCCH资源等)。调度请求采用on-off传输机制，即当终端有调度请求时，在相应的资源上传输PUCCH；当终端无调度请求时，相应资源上不发送任何信息。对于调度请求SR传输由如下结论：一个SR的传输周期最小等于X个OFDM符号(至少针对使用短PUCCH传输的SR)，对于X的取值目前的工作假设为1。
当SR周期非常短时，在一个时隙slot内(包含14个符号)会有多个SR传输资源。当使用长PUCCH传输的其他上行控制信息同时在该slot内传输时，由于时域上存在多个SR传输资源，因此基站无法很好的依靠调度避免其他上行控制信息域SR碰撞，可能会出现如下情况：
1.其他上行控制信息使用PUCCH的传输时间长度大于传输SR的短PUCCH(如图1所示)
2.两个信道在时域上部分重叠(如图2所示)
此时若将SR信息嵌入到传输其他上行控制信息的信道中传输，将会增加SR的传输时延，对于时延敏感性业务是不可接受的。因此，对于不 能支持同时发送多个上行控制信道的终端，此时如何工作尚无明确方案。

为了更清楚地说明本发明的技术方案，接下来举一个典型的例子：
终端判断T与P是否满足第一约定关系。
如果满足第一约定关系，则终端在目标上行控制信道中同时传输SR和其他上行控制信息。例如P小于或等于K*T，其中K>0，K为恒定常数或由基站配置，较优的，K＝1。优选地，SR与其他上行控制信息进行联合编码后映射到目标上行控制信道中传输
如果不满足第一约定关系，则终端使用目标上行控制信道中第一类时域符号传输其他上行控制信息。具体而言有4种方法传输。
方法A：
终端侧行为：终端在SR对应的频域资源上发送SR，第一类时域符号为目标上行控制信道中所有时域符号中除实际传输SR所使用的时域符号之外的时域符号，如图5所示。
基站侧行为：基站首先在SR对应资源上检测是否有SR。若有SR，则对应时域符号不接收目标上行控制信道。若无SR，则对应时域符号上接收目标上行控制信道。
方法B：
终端侧行为：终端在SR对应的频域资源上发送SR，第一类时域符号为目标上行控制信道中所有时域符号中除SR时域资源外的之外的时域符号，如图6所示。
基站侧行为：基站在SR对应时域符号不接收所述第一上行控制信道。
方法C：
终端侧行为：终端在目标上行控制信道所在的频域资源上发送SR，第一类时域符号为目标上行控制信道中所有时域符号中除实际传输SR时域资源外的之外的时域符号。如图7所示。
基站侧行为：基站首先在目标上行控制信道所在的资源上检测是否有SR。若有SR，则对应时域符号不接收目标上行控制信道。若无SR，则对应时域符号上接收目标上行控制信道。
方法D：
终端侧行为：终端在目标上行控制信道所在的频域资源上发送SR，第一类时域符号为目标上行控制信道中所有时域符号中除SR时域资源外的之外的时域符号。如图8所示。
基站侧行为：基站在SR对应时域符号不接收所述第一上行控制信道。
在一个优选例中，终端判断目标上行控制信道的频域资源大小是否不 小于SR对应的频域资源大小。如果是，则使用方法C或方法D，否则使用方法A或方法B。
SR的传输方法有两种，一种是on-off方式(适用于方法A、B、C、D)，另一种是序列选择方式(只适用于方法D)。如图9所示。
on-off方式：当SR为正时，终端使用约定序列进行传输；SR为负时，终端不传输任何信息。相应的基站侧行为：基站首先在SR对应资源上检测是否有SR；若有SR，则对应时域符号不接收所述第一上行控制信道；若无SR，则对应时域符号上接收所述第一上行控制箱信道。
序列选择方式(只适用于方法d)：当SR为正时，终端传输第一约定序列；SR为负时，终端传输第二约定序列。相应的基站侧行为：基站在SR对应时域符号不接收所述第一上行控制信道。
本发明的各方法实施方式均可以以软件、硬件、固件等方式实现。不管本发明是以软件、硬件、还是固件方式实现，指令代码都可以存储在任何类型的计算机可访问的存储器中(例如永久的或者可修改的，易失性的或者非易失性的，固态的或者非固态的，固定的或者可更换的介质等等)。同样，存储器可以例如是可编程阵列逻辑(Programmable Array Logic，简称“PAL”)、随机存取存储器(Random Access Memory，简称“RAM”)、可编程只读存储器(Programmable Read Only Memory，简称“PROM”)、只读存储器(Read-Only Memory，简称“ROM”)、电可擦除可编程只读存储器(Electrically Erasable Programmable ROM，简称“EEPROM”)、磁盘、光盘、数字通用光盘(Digital Versatile Disc，简称“DVD”)等等。
需要说明的是，本发明各设备实施方式中提到的各单元都是逻辑单元，在物理上，一个逻辑单元可以是一个物理单元，也可以是一个物理单 元的一部分，还可以以多个物理单元的组合实现，这些逻辑单元本身的物理实现方式并不是最重要的，这些逻辑单元所实现的功能的组合才是解决本发明所提出的技术问题的关键。此外，为了突出本发明的创新部分，本发明上述各设备实施方式并没有将与解决本发明所提出的技术问题关系不太密切的单元引入，这并不表明上述设备实施方式并不存在其它的单元。
需要说明的是，在本专利的申请文件中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。本专利的申请文件中，如果提到根据某要素执行某行为，则是指至少根据该要素执行该行为的意思，其中包括了两种情况：仅根据该要素执行该行为、和根据该要素和其它要素执行该行为。多个、多次、多种等表达包括2个、2次、2种以及2个以上、2次以上、2种以上。
在本申请提及的所有文献都在本申请中引用作为参考，就如同每一篇文献被单独引用作为参考那样。此外应理解，在阅读了本申请的上述讲授内容之后，本领域技术人员可以对本申请作各种改动或修改，这些等价形式同样落于本申请所要求保护的范围。
