Abstract: Uplink waveforms for operating long term evolution (LTE) in an unlicensed band (i.e., long term evolution-unlicensed (LTE-U) communication) are disclosed. Carrier aggregation (CA) and standalone (SA) are disclosed. LTE on the licensed channel may provide both control and data, LTE on the unlicensed channel may provide data. Managing variable transmission time interval (TTI) continuous transmission is disclosed for transmission over multiple subframes of an unlicensed carrier in LTE-U. Listen-before-talk (LBT) requirements of unlicensed carriers provide for additional channel occupancy constraints when scheduling resources for multiple UEs for variable TTI continuous uplink transmissions over multiple subframes. A joint control channel is disclosed that provides control information for all of the potentially available subframes to be scheduled for the uplink transmissions. In addition to management of the variable TTI continuous transmissions, adjustments to uplink signal parameters are also disclosed that address the constraints due to the LBT requirements of unlicensed carriers.

Abstract: A control scheme using packet headers allows GSM EDGE Radio Access Network (GERAN) systems to increase spectral efficiency through multiplexing techniques, such as superposition coding, multi-user packet transmission, joint detection, and/or joint decoding. A fast feedback scheme for GERAN allows Voice over Internet Protocol (VoIP) frames to be transmitted over GERAN air interfaces without excessive feedback latency. As a result, Hybrid Automatic Repeat-reQuest (H-ARQ) acknowledgements may be timely provided for end-to-end VoIP calls that traverse GERAN air interfaces. Additionally, Incremental Redundancy H-ARQ and link quality feedback latencies are decreased.

Abstract: Downlink power control commands are mapped to resources used for uplink communications within a wireless communication system. A base station receives communications from UEs and determines the resources used by the UEs for those transmissions on the uplink which are transmitted at non-optimum power levels. Power control messages are formulated wherein the location of the power control commands is mapped to particular resources used by the UEs for their uplink transmissions. This facilitates the base station to dynamically assign resources for the power control commands while permitting the UEs to decode the power control messages to adjust their power accordingly.

Abstract: Methods and apparatus for performing radio resource management (RRM) measurements in a heterogeneous network (HetNet) are provided in an effort to prevent failure of RRM measurement procedures in a dominant interference scenario. Several alternatives are provided for determining particular resources (e.g., subframes) to use for performing the RRM measurements, wherein the particular resources are based on cooperative resource partitioning between cells of the HetNet, wherein the cells may be of different types (e.g., macro, pico, or femto cells). These alternatives include, for example: (1) intra-frequency or intra-RAT (radio access technology) alternatives, which may involve transmitting resource partitioning information (RPI) in or deriving non-serving cell RPI based on the serving cell's RPI, as well as (2) inter-frequency or inter-RAT alternatives, where the RRM measurements may be performed during a measurement gap.

Abstract: Systems and methods for facilitating inter-cell interference coordination using load indication are described. A UE may receive load indicator signals from a plurality of base stations in adjacent cells and determine, based at least in part on the load indicator signals, a transmit power metric. The transmit power metric may be provided to a serving base station, which may allocate uplink resources based on the transmit power metric. Additional information related to receiver sensitivity and/or path loss may be used to determine the transmit power metric.
