Patent ID: 11063727

Abstract:
The present disclosure provides a method and a device in User Equipment and a base station for multi-antenna system. The UE first receives a first signaling, a second signaling, a first reference signal and a second reference signal; and transmits first channel information. The first and second reference signals respectively comprises Q1 RS port(s) and Q2 RS port(s), the Q1 RS port(s) and Q2 RS port(s) are respectively transmitted by Q1 antenna port(s) and Q2 antenna port(s). The first signaling and second signaling are respectively used to determine L1 antenna port(s) and Q1 antenna port(s), the Q1 antenna port(s) is(are) a subset of the L1 antenna port(s). Herein, the Q1 and Q2 are positive integers respectively, the L1 is a positive integer greater than or equal to the Q1. The first channel information corresponds to Q antenna ports, the Q is a sum of the Q1 and Q2.
