Abstract: Apparatus and methods for performing reduced hybrid automatic repeat request (HARQ) operations for a user equipment (UE) during a data communications session, e.g., for voice over LTE (VoLTE) communications. The UE can initially inform the network, via an enhanced NodeB (eNodeB), that the UE is capable of performing advanced HARQ functions. The eNodeB can further evaluate various network conditions to determine when reduced HARQ operations should be employed. When network conditions allow, the eNodeB can transmit an RRC message to the UE, including reduced HARQ timeline configuration information. Thereafter, the UE and the eNodeB can collaborate to institute the reduced HARQ timeline to schedule an application data retransmission during the data communications session. The reduced HARQ operations can be performed in conjunction with various semi-persistent scheduling (SPS) and connected mode discontinuous reception (C-DRX) operations, to further conserve UE device resources.

Abstract: The disclosure describes apparatus and methods for including downlink control information (DCI) normally associated with the physical downlink control channel (PDCCH) within a physical downlink shared channel (PDSCH) to reduce power consumption for a user equipment (UE) operating in a Long Term Evolution (LTE) radio resource control (RRC) connected mode. An enhanced NodeB base station can be configured to generate DCI associated with a future downlink resource assignment or uplink grant for the UE on the PDSCH or a physical uplink shared channel (PUSCH), and then include this DCI within the payload of a current PDSCH communication, such that the PDCCH does not need to be decoded by the UE during a time when DCI for future PDSCH communication is included within a current PDSCH.

Abstract: This disclosure relates to aligning semi-persistent scheduling (SPS) uplink and downlink communications. In one embodiment, a cellular base station may select SPS parameters for a wireless device. The SPS parameters may include a subframe offset, a downlink SPS interval, and an uplink SPS interval. The subframe offset may indicate a subframe at which both an initial downlink subframe and an initial uplink subframe are scheduled. An indication of the SPS parameters may be transmitted to the UE. The wireless device and the cellular base station may perform uplink and downlink communication according to the SPS parameters.
