Abstract: Methods and apparatuses to reduce resource consumption by a mobile wireless device when decoding control channel information, such as a physical downlink control channel (PDCCH), in a subframe received from an LTE wireless network are disclosed. Representative methods include demodulating a first set of one or more PDCCH OFDM symbols contained in the subframe based on a first channel estimate; obtaining a second channel estimate based on a second OFDM symbol before demodulating a second set of one or more PDCCH OFDM symbols contained in the subframe based on both the first channel estimate and the second channel estimate. When the PDCCH indicates no downlink assignments for the subframe, the mobile wireless device enters a reduced power consumption mode after demodulating the PDCCH.

Abstract: Apparatus and methods are disclosed for performing delayed hybrid automatic repeat request (HARQ) communications in the downlink (DL) to reduce power consumption for a user equipment (UE) during a connected mode discontinuous reception (C-DRX) cycle. An enhanced NodeB can be configured to monitor a physical uplink control channel (PUCCH) for DL HARQ information to determine when the PUCCH contains a negative acknowledgement (NACK) message, and in response to determining that the PUCCH contains a NACK message, the eNodeB can wait until a next C-DRX ON duration to transmit a HARQ DL retransmission. The eNodeB can also determine whether or not to bundle the HARQ DL retransmission in consecutive transmission time intervals, based on a signal to interference plus noise ratio (SINR) associated with the UE.

Abstract: This disclosure relates to optimizing power consumption for cellular communication based on transport block size in combination with channel condition measurements via power amplifier biasing. According to one embodiment, an indication of a transport block size to be used for uplink communication with a base station may be received. It may be determined that the transport block size provides more robust communication characteristics than required for current channel conditions. A power amplifier (PA) bias current for uplink communication with the cellular base station may be selected based at least in part on determining that the transport block size provides more robust communication characteristics than required for the current channel conditions. In particular, PA bias current selection may be biased to reduce power consumption at a cost of greater non-linearity based on the transport block size providing more robust communication characteristics than required for the current channel conditions.
