摘要： A method for sending a multi-rate multi-receiver message containing a multi-receiver multi-response aggregate. The multi-rate multi-receiver aggregate is transmitted until a multi-receiver multi-response aggregate embedded within the multi-rate multi-receiver aggregate is encountered. Transmission of the multi-rate multi-receiver aggregate is suspended for a predetermined time period. After the expiration of the predetermined time period, transmission of the multi-rate multi-receiver aggregate resumes.

摘要： In accordance with an example embodiment, there is disclosed herein an apparatus where transmitter operating parameters are adjusted based on channel condition data obtained from a transmitter and/or from a receiver communicating with the transmitter. For example, the transmitter's contention window may be increased responsive to determining channel occupancy at the receiver is increasing. As another example, aggregation/fragmentation may be adjusted based on channel occupancy at the receiver. Still another example, the data rate employed by the transmitter may be changed responsive to changes in receiver success count.

摘要： A method for evaluating number of additional admissible calls for use in call admission control includes tracking a percentage of channel busy time and transmission time of downlink and uplink voice packets, receiving a call admission request, and calculating the number of admissible calls. The number of admissible calls is calculated based on a channel bandwidth requirement determined from the percentage of channel busy time and a voice packet queuing requirement determined from the transmission time of downlink and uplink voice packets. The call admission request is approved if the number of admissible calls is greater than one and rejected if the number of admissible calls is less than one.

摘要： A technique for multiple receiver aggregation that allows for multiple immediate responses of acknowledgements or block acknowledgements. The technique uses a spoofed network allocation vector (NAV) implemented within an aggregate's PLCP header to protect the aggregate and all of the immediate responses from multiple receivers. The immediate responses are scheduled, the information indicating the scheduled offset time and granted transmission duration for response of each receiver being included in the physical sublayer data unit (PSDU) headers within the aggregate.

摘要： Reducing latencies for content protection in audio/video networks includes reserving a wireless channel for a time period to accommodate control message exchange for content protection in data communication between a wireless transmitter and wireless receiver over a wireless channel. The control message exchange includes wirelessly transmitting a control request message from the transmitter for content protection to the receiver, and transmitting a control response message from the receiver to the transmitter in reply. Reserving the wireless channel includes reserving the wireless channel for a time period that accommodates the control message exchange. The time period includes a single transmission opportunity period for communication on the wireless channel, to reduce latency for the control message exchange between the transmitter and receiver.
