    Abstract: Embodiments disclosed herein for MAC processing for efficient use of high throughput systems and that may be backward compatible with various types of legacy systems. In one aspect, a data transmission structure comprises a consolidated poll and one or more frames transmitted in accordance with the consolidated poll. In another aspect, a Time Division Duplexing (TDD) data transmission structure comprises a pilot, a consolidated poll, and zero or more access point to remote station frames in accordance with the consolidated poll. In one aspect, frames are transmitted sequentially with no or substantially reduced interframe spacing. In another aspect, a guard interframe spacing may be introduced between frames transmitted from different sources, or with substantially different power levels. In another aspect, a single preamble is transmitted in association with one or more frames. In another aspect, a block acknowledgement is transmitted subsequent to the transmission of one or more sequential frames.

    Abstract: Disclosed is a method for facilitating in-order processing of data packets in wireless communication handover which is performed by at least one apparatus in a wireless communication network. Firstly, a handover command for transferring the communications of a mobile device (402) to a target base (412) station is received. A sequence index of a last service data unit received in order from the mobile device (402) is determined. The sequence index is then transmitted to the target base station (412) in response to the handover command. Wireless communications apparatuses for performing this method are also disclosed.

    Abstract: Methods and apparatus are described comprising receiving, at a station, a slow delivery traffic identification message, DTIM, sent at a slower rate than a regular DTIM, with the regular DTIM indicating first broadcast and multicast traffic and the slow DTIM indicating second broadcast and multicast traffic; and receiving the second broadcast and multicast traffic as indicated by the slow DTIM.

    Abstract: The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network. While communicating over the packet-switched network, the device negotiates a sleep interval that is longer than the ordinary interval available using the packet-switched network. In this manner, the device wakes less frequently and thereby conservers power. A buffering system is included so that data directed towards the device while it is asleep may be buffered for later delivery when the device awakens.

    METHOD AND APPARATUS FOR POLLING IN A WIRELESS COMMUNICATION SYSTEM

    Abstract: METHOD AND APPARATUS FOR POLLING IN A WIRELESS COMMUNICATION SYSTEMA data packet communication system employs radio link control (RLC) transmission between a transmitter and a receiver with an Automatic Repeat Request (ARQ) arrangement whereby polling of the receiver is accomplished with reduced amount of redundantly transmitted data, such as between an access node and terminal. Upon a polling event, such as emptying of a transmission buffer of the transmitter, expiration of a polling timer, or reaching a radio link control (RLC) protocol data units (PDUs) count threshold, the transmitter sends a polling command to the receiver. This polling command is smaller than any of the RLC PDUs, which are conventionally resent with a polling bit set to evoke a STATUS PDU from the receiver. With evolving communication standards tending toward larger PDUs, such as in excess of a kilobyte for HSPA+ (High-Speed Packet Access Evolution) and 3GPP LTE (Long Term Evolution), this inefficiency can be of increasing impactFigure 1

    Abstract: An apparatus that facilitates continuous sequencing of packets for transmission through a handoff is disclosed. The apparatus comprises: (a) means for receiving one or more selectively forwarded packets for communication in connection with a handoff; (b) means for identifying state information and order information associated with the packets that facilitate lossless delivery of the packets, where at least a portion of the identifying means includes sequence number information forwarded directly from a source eNode B to a target eNode B; and (c) means for transmitting respective packets subsequent to the selectively forwarded packets using the state information in an order specified by the order information.
