Dynamic DMRS mode switching

And performing dynamic DMRS mode switching. In one aspect of the present disclosure, a method, computer readable medium, and apparatus are provided. The apparatus may be a UE. In certain configurations, a UE receives a message having a demodulation reference signal (DMRS) switching bit that indicates which of a first DMRS mode or a second DMRS mode is being used. And the UE determines the DMRS mode being used according to the DMRS switching bit. The UE applies the determined DMRS mode being used to the processing of the uplink channel and the downlink channel. 动态DMRS模式切换。在本公开的一方面，提供了一种方法、计算机可读介质和装置。该装置可以是UE。在某些配置中，UE接收具有解调参考信号(DMRS)切换位的消息，该DMRS切换位指示第一DMRS模式或第二DMRS模式中的哪个DMRS模式正被使用。UE根据DMRS切换位确定正被使用的DMRS模式。UE将所确定的正被使用的DMRS模式应用于上行链路信道和下行链路信道的处理。
