Title
(EN) TRANSMITTING MULTIPLEXED SOUNDING REFERENCE SIGNAL PORTS IN NEW RADIO
(ZH) 在新无线电中发送经复用的探测参考信号端口
Abstract
(EN)
Certain aspects of the present disclosure relate to methods and apparatus for transmitting multiplexed sounding reference signal (SRS) ports in communications systems operating according to new radio(NR) technologies. An exemplary method includes obtaining an indication of a technique to use in transmitting sounding reference signals (SRS) via five or more antenna ports in one slot and transmitting the SRS via the five or more antenna ports according to the indicated technique.
