Abstract
While a user equipment (UE) is in a connected mode, the UE may receive only a limited quantity of data. During this phase, a receive diversity configuration may not be enabled, in an effort to conserve power on the UE side. However, in marginal signal conditions and a poor radio environment, downlink performance at the UE side may be enhanced by enabling receive diversity, irrespective of the limited data received by the UE. However, while receive diversity may improve the signal-to-noise ratio (SNR) at the UE end in marginal signal conditions, the UE may also incur a penalty on power consumption. Therefore, certain aspects of the present disclosure provide techniques for dynamically controlling the receive diversity of a wireless device to improve the downlink procedure performance, while minimizing power consumption due to the usage of a second receive chain when in connected mode.
