Optimized uplink performance via antenna selection

摘要

Embodiments of the disclosure provide systems and methods for improving user equipment performance in up-link transmission by implementing antenna selection based on channel measurements in the down-link. In various embodiments, first and second antennas are used to receive desired signals on a downlink and to transmit signals on an uplink. A plurality of signals received on the downlink are used to generate a plurality of antenna parameter measurements derived from multiple correlations of a known reference sequence of data signals transmitted on the downlink. The plurality of antenna parameter measurements is then used to select either the first antenna or the second antenna for transmitting data signals by said user equipment device on the uplink.
