  • Patent number: 9894647
    Abstract: Aspects of the present disclosure provide techniques and apparatus for enhancing downlink coverage for certain user equipments (UEs) (e.g., low cost, low data rate UEs). Certain types of UEs may have limited coverage or should receive enhanced coverage relative to other types of UEs. For example, some types of low cost UEs may have only a single receive chain, thereby limiting DL coverage, while other types of UEs benefit from multiple receive chains. One example method generally includes identifying a first type of one or more UEs that is to receive enhanced downlink (DL) coverage relative to a second type of UEs and utilizing one or more DL coverage enhancement techniques when communicating with the first type of UEs, the one or more DL coverage enhancement techniques designed to adjust at least for reduced DL processing gain of the first type of UEs relative to the second type of UEs.

  • Patent number: 9887761
    Abstract: A wireless relay serves a first User Equipment (UE). A first eNodeB in the relay wirelessly exchanges UE signaling data and UE user data with the first UE. The first eNodeB processes the UE signaling data to generate S1-MME signaling data and exchanges the S1-MME signaling data with a second UE in the relay. The first eNodeB processes the UE user data to generate S1-U user data and exchanges the S1-U user data with a Local Serving Gateway (L-SGW) in the relay. The L-SGW terminates the S1-U user data to generate non-General Packet Radio Service Transfer Protocol (non-GTP) user data. The L-SGW exchanges the non-GTP user data with the second UE in the relay. The second UE compresses/decompresses the non-GTP user data and the S1-MME signaling data. The second UE wirelessly exchanges the compressed non-GTP user data the compressed S1-MME signaling data with a second eNodeB.

  • Patent number: 9848414
    Abstract: A method is provided for transmitting a power headroom report at a user equipment (UE) in a wireless communication system. The UE configures a first cell group having a primary cell (PCell) and a second cell group having one or more secondary cells (SCells). The UE transmits the power headroom report. If the first cell group and the second cell group are managed by a same base station, the power headroom report indicates power headroom information regarding the first and second cell groups. If the first cell group and the second cell group are managed by different base stations, the power headroom report indicates power headroom information regarding only one of the first cell group and the second cell group.
