Abstract:
A user equipment (UE) utilizes a first group of antenna ports at the UE for transmitting and receiving while utilizing a second group of antenna ports for receiving but not transmitting. The UE transmits to a base station (BS) a sounding reference signal (SRS) via the first group of antenna ports through a first channel of a communication link between the UE and the BS. The UE receives from the BS a channel state information reference signal (CSI-RS) via the first and second groups of antenna ports through the first channel and a second channel of the communication link. The UE determines an estimated channel response and a matrix such that a product of the matrix and a channel response of the first channel approximates a channel response of the second channel. The UE transmits to the BS a CSI feedback indicating at least the matrix.

Claim (Index 5):
A method, comprising:\n receiving, by a processor of a base station, from a user equipment (UE) a sounding reference signal (SRS) transmitted via a first group of antenna ports of two groups of antenna ports at the UE through a first channel of a communication link between the UE and the base station; transmitting, by the processor, to the UE a channel state information reference signal (CSI-RS) which is received by the UE via the first group and a second group of the two groups of antenna ports through the first channel and a second channel of the communication link; and receiving, by the processor, from the UE a CSI feedback indicating a matrix, a transmission rank, and a channel quality indicator (CQI), wherein the UE uses the first group of antenna ports for both transmitting and receiving, wherein the UE uses the second group of antenna ports for receiving but not transmitting, and wherein a product of the matrix and a channel response of the first channel approximates a channel response of the second channel.
