METHODS AND APPARATUS FOR ENHANCEMENT OF SRS

Abstract: according to embodiments, a ue receives, from a network device, a configuration of a sounding reference signals (srs) resource with 8 antenna ports, a transmission comb configuration for the srs resource, and a cyclic shift (cs) configuration for the srs resource. the transmission comb configuration indicates a comb value k. k is one of 2, 4, or 8. the transmission comb configuration further indicates a configured comb offset (k). k is an integer between 0 and k−1. the cs configuration indicates cs positions. the ue maps each port of the 8 antenna ports to corresponding resource elements (res) in the frequency domain and a corresponding cs. the corresponding res are a subset of a plurality of res and on every k-th re with an offset based on the configured comb offset (k) within an srs transmission bandwidth. the ue transmits srss using the 8 antenna ports based on the mapping.
