Abstract
Techniques for limiting cell reselection in response to a variable channel are disclosed. In one aspect, a measurement of received pilot power from a base station is used as an indication of channel quality. In another aspect, hysteresis is applied to limit cell reselection, wherein the hysteresis is greater in relatively higher quality channel environments and lower in relatively lower channel quality environments. Various other aspects are also presented. These aspects have the benefit of reducing cell reselection, thus increasing time spent in low-power mode, thereby reducing power consumption and increasing standby time.
