Abstract:
1. A method for antenna selection (AS) in a wireless communication network, the network comprising a base station and a transceiver, wherein the transceiver has a set of antennas, and wherein the transceiver is configured to transmit a frequency-hopped sounding reference signal (SRS) from a subset of antennas at a time, comprising at the base station: determining a type of a training transmission based on a number of the subbands and a number of subsets in the set of antennas, wherein the type is a transmitting substantially alternately, if the number of subbands is an integer multiplier of the number of subsets, and wherein the type is a transmitting alternately, if the number of subbands is not the integer multiplier of the number of subsets; and transmitting an instruction including the type to the transceiver, such that the transceiver is instructed to transmit the SRS from each subset in the set of antennas alternately, if the type is the transmitting alternately, and is instructed to transmit the SRS from each subset in the set of antennas alternately, while periodically altering an index of a transmitting subset, if the type is the transmitting substantially alternately.
