  • Devices and methods for facilitating signal-to-interference ratio estimates for closed-loop transmission diversity communications
    Patent number: 9531483
    Abstract: UEs are adapted to facilitate calculation of signal-to-interference ratio (SIR) estimates in closed-loop transmission diversity (CLTD) communications before downlink and uplink synchronization is achieved. A UE may receive a transmission sent using transmission diversity. According to one example, the UE may calculate a plurality of signal-to-interference ratio (SIR) estimates for the received transmission, where each signal-to-interference ratio estimate is calculated using a different weight factor. The UE may further select one of the calculated signal-to-interference ratio (SIR) estimates to be employed for the received transmission. According to another example, the UE may calculate a signal-to-interference ratio (SIR) estimate for the received transmission without employing any weight factor. Other aspects, embodiments, and features are also included.
