Abstract: A system and method are provided for controlling bandwidth allocation in a wireless local area network (wLAN). The method comprises: expressing device bandwidth allocations in terms of a time base; in response to expressing the bandwidth allocation in terms of a time base, monitoring network communications; and, measuring the allocated bandwidths. The method may further comprise: establishing polling schedules in response to the time-based bandwidth allocation; and, de-energizing devices in response to the polling schedules. Expressing device bandwidth allocations in terms of a time base includes establishing: an inter-transmission opportunity (TXOP) interval; and, a TXOP jitter. These fields are supplied in the IEEE 802.11e transmit specification (TSPEC). Then, de-energizing devices in response to the polling schedule includes disengaging transmission and receiving functions in the minimum TXOP intervals between polling events, where the minimum TXOP interval is the inter-TXOP interval minus the TXOP jitter.

Abstract: A mobile device in a communication system executes transmitting and/or receiving in any of sequential slots each having a fixed time interval. The mobile device receives downlink data from a base station and indicates a successful receipt or an unsuccessful receipt of the downlink data to the base station. In a case of the unsuccessful receipt, the mobile device receives retransmission downlink data from the base station in a slot that is equal to or more than a first number of slots after a slot in which the downlink data has been received. The mobile device activates reception for the retransmission downlink data in the slot that is the first number of slots after the slot in which the downlink data has been received.

Abstract: A method and system for optimizing channel quality indicator (CQI) transmissions by mobile devices in a cellular network allows transmission of CQIs at a slower rate and with fewer bits during voice-over-internet-protocol (VoIP) sessions than during non-real-time (NRT) data transmissions. A VoIP transmission typically includes "talkspurt" periods, during which VoIP packets are transmitted, and silence periods, which start with a silence indication (SID) packet and continue with periodic SID packets until a VoIP packet is received. When the base station is transmitting NRT data, the mobile device transmits CQIs to the base station at a first rate, with each CQI having a first fixed number of bits. When the base station is transmitting VoIP to the mobile device, then during a talkspurt period, the mobile device may transmit CQIs to the base station at a second rate slower than the first rate, and each CQI may have a second fixed number of bits less than the first fixed number of bits. However, during a silence period, the mobile device does not transmit CQIs to the base station, and uplink channel resources allocated for the CQIs can be reallocated to other mobile devices.

Abstract: Embodiments of the present invention comprise methods and systems for MAC layer acknowledgement of the receipt of network data in a multicast transfer environment. Some embodiments include methods wherein data is sent from a source to a MAC layer multicast address followed by separate acknowledgement requests, which are sent to each data recipient's MAC layer unicast address. Each recipient may then acknowledge receipt of the multicast data thereby allowing the source to resend any lost data. The MAC layer acknowledgement of these embodiments allows fast quality of service assurance compatible with demanding audio and video applications where higher level acknowledgement is not effective
