    Abstract: Methods and apparatus for managing radio measurements during discontinuous reception. In one exemplary embodiment, the distribution of Long Term Evolution (LTE) DRX measurements is staggered or distributed across multiple DRX cycles (which may be contiguous or non-contiguous) so as to reduce the transceiver activity and power consumption. The exemplary UE in one implementation only performs a subset of measurements during each DRX cycle. By staggering or distributing cell measurements over multiple DRX cycles, the UE can improve power consumption, while still conforming to measurement requirements.

    Abstract: A station performing a method to toggle a channel estimation setting between a full channel estimation that includes estimating the channel based upon a predetermined number of received reference symbols prior to a current subframe and a partial channel estimation that includes estimating the channel based upon a subset of the predetermined number of received reference symbols. The method includes changing the setting from full to partial when a predetermined number of consecutive subframes immediately prior to the current subframe had no downlink allocated and a reliability value indicates that control signals are capable of being reliably received. The method also includes changing the setting from partial to full when the current subframe had a downlink allocated thereto or the reliability value indicates that the control signals are incapable of being received to estimate the channel using the partial channel estimation.

    Abstract: Methods and apparatus for correcting quantization errors in signal reception based on estimated network loading including solutions for preserving cellular network performance in low noise, high interference environments. In one embodiment, a data channel is amplified with respect to other signals based on network load during periods of relatively low network utilization. Dynamic modification of the data channel's power level is configured to overcome quantization errors, rather than the true noise floor (which is insignificant in low noise environments). Such solutions provide both the fidelity necessary to enable high degrees of unwanted signaling rejection, while still preserving data channel quality.
