    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: Performing cell re-selection by a wireless user equipment (UE) device. A first cell on which to camp may be selected. The UE may camp on the first cell in an idle-mode. The UE may be configured to perform searches for neighboring cells according to an idle-mode timeline while camping on the first cell. The UE may transmit a connection request to the first cell in order to transition the UE from the idle-mode to a connected-mode via the first cell. One or more searches for neighboring cells may be performed according to a connected-mode timeline after transmitting the connection request, in response to transmitting the connection request. The one or more searches may be performed before the UE establishes the connected-mode with the first cell.

First channel quality information may be generated and transmitted to the BS. A first MCS allocation, which may be based at least in part on the first channel quality information, may be received from the BS. Second channel quality information may be generated and transmitted to the BS, where the second channel quality information is modified by an offset configured to modify a second MCS allocation.

    Abstract: A wireless communication system is presented in which subframe-specific link adaptation is performed. A mobile device can transmit a signal that informs a base station whether a particular subframe was received successfully. Additionally the mobile device can calculate channel state information (CSI) for a subframe and report the CSI to a base station. The reported CSI may or may not include an indicator for informing the base station about from which type of subframe the CSI was derived. The base station can receive the signal, the CSI and/or the indicator. Based on what information the base station has received, it performs subframe-specific BLER filtering and subframe-specific link adaptation scheduling and MCS adjustments.
