[0045] Summary-

[0046] So-called receiver diversity techniques are widely used in several wireless network standards such as Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), Wireless Microwave Access (WiMAX), etc. to improve reception performance. During diversity operation, a mobile device, such as a user equipment (UE), receives transmissions via two or more different communication channels, where each of the different communication channels experiences different fading and interference effects. By combining transmissions from different communication channels, diversity operation compensates for fading and interference effects, which greatly improves device reception.

[0047] Unfortunately, diversity techniques consume significantly more power than non-diversity operation. However, the performance gain from receiver diversity is not always predictable. T...

Abstract

Methods and apparatus for adaptively adjusting receiver operation for e.g., power optimization. In one embodiment, operation during diversity operation is adaptively adjusted. Diversity techniques consume significantly more power than non-diversity operation. However, the performance gain from receiver diversity is not always predictable. Consequently, in one embodiment, a device evaluates the overall performance gain contributed by diversity operation and, where the performance gain is insignificant or inadequate, the device disables diversity operation. In one implementation, the device can operate in a static single antenna mode, a dynamic single antenna mode and a dynamic multi-antenna mode.
