Antenna selection with frequency-hopped sounding reference signals

摘要

The embodiments of the invention describe a method for antenna selection in a wireless communication network. The network includes a transceiver having a set of antennas. The transceiver is configured to transmit a frequency-hopped sounding reference signal (SRS) over a subband from a subset of antennas at a time. The transceiver transmits the frequency-hopped SRS from subsets of antennas in the set of antennas substantially alternately. In response to the transmitting, the transceiver receives information indicative of an optimal subset of antennas and transmits data from the optimal subset of antennas.

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 frequency-hopped sounding reference signal (SRS) over a subband from a subset of antennas at a time, comprising in the transceiver:
receiving an instruction regarding a type of the transmission; transmitting the frequency-hopped SRS from subsets of antennas in the set of antennas alternately so that the SRSs are transmitted from each subset in the set of antennas alternately, and periodically an order of subsets schedule for the transmission is altered; receiving, in response to the transmitting, information indicative of an optimal subset of antennas; and transmitting data from the optimal subset of antennas.
