Optimized uplink performance via antenna selection |
摘要 |
<p>Embodiments of the invention 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 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 or a combination of both through splitting of the signal for transmitting data signals by said user equipment device on the uplink.
