摘要： A method and system for wireless communication in a wireless network is provided. One implementation involves a requesting wireless station directionally transmitting a request to a coordinator for access to a communication channel; the request packet includes a field indicating the length of the desired reservation period; and upon successfully receiving the request from the wireless station, the coordinator reserving a channel time period for data transmission by the requesting wireless station, and at least pseudo-omni-directionally broadcasting a packet to all wireless stations in the network indicating the reservation. All other stations refrain from contending the channel during the reserved channel time period.

摘要： Wireless communication between a first transmitter and a first receiver for a new transmission is established on the same wireless data channel used for ongoing transmission between a second transmitter and a second receiver. This is achieved by determining if the second receiver can receive signals from the first transmitter, and determining if the first receiver can receive signals from the second transmitter. If the second receiver cannot receive signals from the first transmitter, and the first receiver cannot receive signals from the second transmitter, then a new transmission is performed from the first transmitter to the first receiver by spatial reuse of the wireless data channel at least partially concurrently with said ongoing transmission on said data channel.

摘要： An apparatus and method for achieving power saving for a portable device in a wireless network for transmitting audio/video (A/V) data is disclosed. An optimal transmit power level is selected by transmitting multiple probe messages by a portable device at increasing transmit power levels until a response to one of the probe messages is received within a preset allowed response time. A relay node is selected by a portable device for receiving compressed A/V data, uncompressing the compressed A/V data, and transmitting the uncompressed A/V data to an intended receiver.
