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 translation: 用于在数据通信会话期间（例如，对于LTE（VoLTE）语音通信）的用户设备（UE）进行减少的混合自动重复请求（HARQ）操作的设备和方法。 UE可以最初通过增强型节点B（eNodeB）通知该网络UE能够执行高级HARQ功能。 eNodeB可以进一步评估各种网络条件以确定何时应采用减少的HARQ操作。 当网络条件允许时，eNodeB可以向UE发送RRC消息，包括减少的HARQ时间线配置信息。 此后，UE和eNodeB可以协作来实现减少的HARQ时间线，以在数据通信会话期间调度应用数据重传。 减少的HARQ操作可以结合各种半静态调度（SPS）和连接的模式不连续接收（C-DRX）操作来执行，以进一步节省UE设备资源。

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.
