    Abstract: The subject matter disclosed herein provides methods and apparatus for determining a singular value decomposition, providing feedback from a client station to a base station, and closed loop operation of a wireless system implementing multiple-input multiple-output (MIMO). The method may include determining one or more singular vectors using a closed form singular value decomposition. The one or more determined singular vectors may be provided to a precoder at the base station as feedback. The method may include aligning a phase of one or more singular vectors. The method may also include determining, at a client station, a plurality of singular vectors for channels used in a MIMO transmission from a base station to a client station. The client station may provide an indication to the base station regarding whether to use a singular value decomposition or a uniform channel decomposition. Related systems, apparatus, methods, and/or articles are also described.

    Abstract: A system for controlling a contention state for a communication link between a base station controller and customer premises equipment in point-to-multipoint communication. The contention state is controlled using a state machine, which includes a grant pending absent state in which a unicast request slot is maintained open for use by the customer premises equipment. During the grant pending absent state, the customer premises equipment sends no upstream data to the base station controller but can use the unicast request slot to request a data slot for sending upstream data to the base station controller. In the grant pending state, the customer premises equipment preferably uses piggybacking to request grant of a next data slot while sending upstream data to the base station controller.

    Abstract: Methods and apparatus permitting the coexistence of multiple communication links to distinct wireless systems in a client device are disclosed. A wireless device can interface with both a primary communications system and at least one distinct communications system by managing the coexistence of active communications with the multiple communication systems. The wireless device can initially configure communications with the primary communications system for dynamically reconfigurable time multiplexed operation having scheduled periods of inactivity. The wireless device can determine timing and scheduling of communications with the distinct communications systems and can schedule the communications with the distinct communications systems during periods of inactivity in the primary communications system. The periods of inactivity may be limited to the scheduled periods of inactivity or can include unscheduled periods of inactivity occurring during active periods of the time multiplexed operation. The device may also use data priorities of communications to override overlapping communication activity.

    Abstract: Methods and apparatus are described for determining, via a Hybrid Automatic Repeat Request (HARQ) module, that a maximum number of retransmissions has been reached for a HARQ packet. The HARQ module may communicate an internal NACK to a message retransmission module indicating a transmission failure. The message retransmission module may retransmit at least a part of the message. The retransmission may be performed prior to the expiration of a timer.
