  • Patent number: 9949253
    Abstract: A method for communicating data between a base station and a terminal device in a wireless telecommunications system, for example an LTE-based system. The wireless communication system uses plural frequency sub-carriers spanning a system frequency band. Physical-layer control information for the terminal device is transmitted from the base station using sub-carriers selected from across the system frequency band, for example to provide frequency diversity. However, higher-layer data for the terminal device is transmitted using only sub-carriers selected from within a restricted frequency band which is smaller than and within the system frequency band. The terminal device is aware of the restricted frequency band, and as such need only buffer and process data within this restricted frequency band during periods where higher-layer data is being transmitted. The terminal device buffers and processes the full system frequency band during periods when physical-layer control information is transmitted.

  • Patent number: 9942846
    Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for a user equipment (UE) to delay RLC retransmissions (e.g., during off-durations, including CDRX off-durations). According to aspects of the present disclosure, a UE may delay triggering an RLC retransmission of an RLC PDU until after a next opportunity for the UE to receive an RLC ACK of the RLC PDU. By delaying RLC retransmissions, a UE may be prevented from waking up from one or more CDRX off-durations and using power associated with waking up from the one or more CDRX off-durations.
