Abstract:
1. A method for antenna selection (AS) in a wireless communication network, the network comprising a transceiver, wherein the transceiver has a set of antennas, and wherein the transceiver is configured to transmit a broadband frequency-hopped sounding reference signal (SRS) over a subband of a bandwidth of a frequency from a subset of antennas at a time, wherein the bandwidth of the frequency includes a plurality of subbands, comprising in the transceiver: determining a type of a transmission based on a relationship between a number of the subbands and a number of the antennas in the set; transmitting, if the number of subbands is not integer multiplier of the number of the antennas, the frequency-hopped broadband SRSs over the plurality of subbands from subsets of antennas in the set of antennas alternately, such that any two subsequently transmitted broadband SRSs are transmitted from different subsets of antennas; receiving, in response to the transmitting, information indicative of an optimal subset of antennas; and transmitting data from the optimal subset of antennas.
