摘要： Transmission of eMBMS signals by at least one network entity of a wireless communications system may include coordinating transmission of eMBMS signaling with a remote access point of a wireless communications system to broadcast the eMBMS signaling from a multiple antenna matrix comprising at least one antenna of the network entity and at least one antenna of the access node. The network entity may be an access point. The access point may vary a precoding matrix applied to the eMBMS signaling to transmit from the network entity, or use alternative techniques for providing transmit diversity. Accordingly, the access point may provide transmit diversity for the eMBMS signaling transmitted from the multiple antenna matrix implemented between different cells on the wireless communication network. The access point may vary the precoding matrix to cause cyclical rotation of beam direction for the eMBMS transmissions from different cells of the network.

摘要： Systems and methodologies are described that facilitate determining control region parameters related to a plurality of carriers and/or coordinated multiple point (CoMP) access points. Wireless devices can receive control region parameters related to the carriers or CoMP access points from a serving access point over control channel resources. Additionally or alternatively, wireless devices can assume all carriers or CoMP access points have substantially the same control region as indicated in a control format indicator channel from the serving access point or based on a configured value.

摘要： A system and method for inter-cell power control for interference management in an OFDM system is provided. The system provides for a combination use of open loop and closed loop PSD control algorithms. The open loop control is a function of path loss from the serving cell as well as the neighboring cells. The closed loop control updates the end node transmit PSD by listening to the load indicators from the serving cell and at least one other neighboring non-serving cell which generates the highest level of interference. The system thus provides a fast and tight control with multi-cell information that allows improved inter-cell interference control.

摘要： Systems and methodologies are described that facilitate defining a new control region over resources allocated for communicating general non-control data in a legacy network specification. The new control region can comprise multiple control channels, which can be multiplexed together and/or with general data channels. Devices can receive control data over the new control region as well as information regarding the region, such as location of the region, location of specific resources, multiplexing schemes, frequency hopping patterns, and/or the like to appropriately decode relevant control data. This allows for expanded control resources to support multicarrier assignments, large numbers of devices being addressed, special operation modes, new downlink control information (DCI) formats, and/or the like.

摘要： Certain aspects of the present disclosure provide methods and apparatus for subframe muting and/or discontinuous reception (DRX) mode related to sleep mode for user equipment (UE) relays. One method generally includes measuring, at a UE functioning as a relay (i.e., a UE relay), signals of one or more other UEs functioning as relays during one or more particular subframes and reporting the measurements of the signals to an apparatus. Another method generally includes determining, at a first UE functioning as a relay, that no UEs are being served by the first UE; based on the determination, increasing an interval between broadcast signals; and transmitting the broadcast signals according to the increased interval.

摘要： Techniques for sending control information on a variable control channel are described. Different structures for mapping control information to control channel resources may be used depending on various factors such as operating configuration, the available resources for the control channel, the type(s) of control information being sent, the amount of control information being sent for each type, whether or not data is being sent, etc. In one design, at least one type of control information being sent may be determined and may comprise channel quality indicator (CQI) information, acknowledgement (ACK) information, and/or other types of control information. A structure of the control channel may be determined based on operating configuration (e.g., system configuration such as asymmetry of downlink and uplink allocations) and/or other factors. The at least one type of control information may be mapped to the resources for the control channel based on the structure.

摘要： 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.

摘要： Systems and methodologies are described that facilitate efficiently indicating parameter(s) associated with a base station utilizing synchronization signals in a wireless communication environment. For instance, relative locations of a PSC and a SSC in a radio frame can be a function of a parameter. Further, a PSC sequence utilized to generate PSCs can be selected based upon a parameter. Moreover, inclusion or exclusion of PSCs from a radio frame can be a function of a parameter. Additionally or alternatively, pseudo random sequence mappings (e.g., to cell IDs, tone locations) can be a function of a parameter. Example parameters can be whether the base station is part of a TDD or a FDD system, whether the radio frame employs FS1 or FS2, whether the base station is associated with a macro or a femto cell, or whether the base station is associated with a unicast or a multicast system.
