  • Optimized uplink performance via antenna selection
    Patent number: 8953474
    Abstract: 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.

  • METHODS FOR DETECTION OF FAILURE AND RECOVERY IN A RADIO LINK
    Publication number: 20130315358
    Abstract: A method, telecommunication apparatus, and electronic device for detecting a status of a radio link are disclosed. A transceiver 302 may maintain a radio link with a network base station 104. A processor 304 may map channel state information to a synchronization status associated with the radio link based on the received signal and determine the synchronization status via a block error rate estimate in the radio link based on the channel state information.
