| 摘要 |
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 (404, 502, 702). 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 (406, 504). The UE may further select one of the calculated signal-to- interference ratio (SIR) estimates to be employed for the received transmission (506). According to another example, the UE may calculate a signal-to-interference ratio (SIR) estimate for the received transmission without employing any weight factor (704). Other aspects, embodiments, and features are also included. employing any weight factor. Other aspects, embodiments, and features are also included. |
