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： Techniques for performing decision feedback equalization are described. A feed-forward filter response and a feedback filter response are derived based on a channel estimate and a reliability parameter and further without constraint on the feedback filter response or with a constraint of no feedback for an on-time sample. The reliability parameter is indicative of the reliability of the feedback used for equalization and may be frequency dependent or frequency invariant. Different feed-forward and feedback filter responses may be derived with different constraints on the feedback filter and different assumptions for the reliability parameter. Equalization is performed with the feed-forward and feedback filter responses. If equalization is performed for multiple iterations then, for each iteration, the reliability parameter may be updated, the feed-forward and feedback filter responses may be derived based on the updated reliability parameter, and equalization may be performed with the filter responses for the iteration.

摘要： Methods and apparatuses are provided that facilitate allocating a portion of a resource block to a power-limited device for communicating therewith. The power-limited device may not be capable of transmitting over an entire resource block due to power limitations; thus, a portion of the resource block can be assigned thereto, allowing for allocating at least a different portion of the resource block to at least one different device to optimize communications over the resource block. In addition, the portion of the resource block can be allocated across one or more bundled time transmit intervals (TTI) to allow for effective communication of time-sensitive data, such as voice over internet protocol (VoIP).

摘要： An equalization filter is provided with the ability to softly switch between pure linear equalization and decision feedback equalization. A reliability gain factor and an associated gain factor calculated by a predetermined mapping relation are provided in a decision feedback path and a feedforward path, respectively. Increasing the reliability gain factor increases the significance of the decision feedback filtering. Better performance than pure linear equalization and pure decision feedback equalization can be achieved.

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： Systems and methodologies are described herein that facilitate control and data multiplexing for uplink (UL) multiple-input-multiple-output (MIMO) communication within a wireless communication system. As described herein, a device conducting uplink MIMO communication in a wireless communication system can multiplex control signaling and data across one or more of a plurality of layers (e.g., corresponding to spatial layers, codewords, etc.) associated with an uplink transmission. Techniques are described herein for selecting layers of a transmission on which to schedule control signaling and selecting offsets to apply to the control signaling scheduled on selected layers. Further, techniques are described herein for leveraging a multi-layer transmission to increase the efficiency of acknowledgement communication. In addition, techniques are described for selecting a modulation and coding scheme (MCS) to apply to control signaling that is combined with data in an uplink multi-layer transmission.
