Abstract
The embodiments of the invention provide a method for selecting antennas for date transmission in a wireless communication network including user equipment (UE). The network is assigned a band of frequencies, wherein the band is partitioned into at least one set of subbands of the band according to a sounding reference signal (SRS) bandwidth configuration in a form of a codetree having a plurality levels and each level is associated with a partition coefficient. The UE is configured to transmit frequency-hopped SRS on the set of subbands using subsets of the set of antennas. First, the method determines if a number of subbands in the set of the subbands is odd or even based on the SRS bandwidth configuration, and selects a particular subset of the antennas according to whether the number is odd or even. Then, the SRS is transmitted from the particular subset of the antennas.
