摘要： A method and an apparatus select an access point (AP) in a wireless LAN to associate or reassociate, based on considerations that take into account the quality-of-service (QoS) status of the stations (STAs) and the potential hidden terminal effect. The method utilizes advertised or requested information obtained from an AP which includes the QoS status in each basic service set (BSS) and estimates the potential hidden terminal (HT) effect based on local channel sensing by the STA. The method selects the AP in a manner that reduces the possibility of collision from equal and higher priority HTs, thus providing greater transmission throughput and improving performance.

摘要： Embodiments of the present invention include a method and apparatus for reducing control signaling overhead in a hybrid wireless network. The method comprises receiving a wireless frame in the hybrid wireless network at a first terminal, and determining whether the received wireless frame is a control frame for a wireless channel reservation; if the received wireless frame is a control frame for the wireless channel reservation, reading by the first terminal a value of Duration field in control frame, and updating a timer for a channel reservation period in the first terminal with the value of Duration field, instead of updating network allocation vector of the first terminal; determining whether the remaining time of the timer for the channel reservation period is longer than the time required for transmitting the data frame or not before transmitting a data frame by the first terminal; and transmitting the data frame directly by the first terminal without transmission of a control frame for the wireless channel reservation if the remaining time is longer than the time required for transmitting the data frame.

摘要： A method for accessing a hybrid network including a wide area network and a distributed network, a gateway apparatus, a wireless terminal and a gateway communication system are disclosed for reducing the power consumption of the wireless terminal which is an access gateway. The method comprises: sensing by a gateway apparatus a relay request slot on a downlink common control channel of the wide area network; transmitting by a wireless terminal a relay request signal requesting to relay a data packet to be transmitted, in the relay request slot on the downlink common control channel; and if the relay request signal from the wireless terminal is sensed in the relay request slot, establishing by the gateway apparatus a connection with the wireless terminal in a distributed network environment. As such, the gateway apparatus accesses the wireless distributed network only when the surrounding wireless terminals require data relay, without sensing signals on both networks simultaneously, in order to reduce the power consumption.
