摘要： A method and apparatus for assigning holding packets in a wireless communication system or network includes determining an invalid station address that corresponds to an invalid station and that does not correspond to the address of an affiliated station. The invalid station address is assigned to a holding packet. The holding packet is transmitted to allocate a transmit period to the invalid station. This generates a quiet time in the wireless communication system or network during the transmit period.

摘要： A method and apparatus for dynamic frequency selection in a wireless communication system or network includes processing that begins when an access point determines interference on a wireless channel that is being used by the access point. When the interference exceeds an interference threshold, the access point provides a request packet to affiliated stations being serviced by the access point for channel spectrum information. The processing continues as the affiliated stations generate the channel spectrum information regarding each of the wireless channels in the wireless communication network. The processing proceeds then as the affiliated stations provide the channel spectrum information to the access point via the current wireless channel. The access point interprets the channel spectrum information to determine a desired wireless channel of the plurality of wireless channels within the wireless communication network. The access point then provides a selection packet to the affiliated stations via the current wireless channel to indicate that the access point will begin using the desired wireless channel at a particular future time.

摘要： A method and apparatus for controlling transmit power of a wireless communication device includes processing that begins when a transmitting wireless communication device transmits a packet to a targeted wireless device via a wireless channel of a communication system at a 1st power level. The processing continues by having the targeted wireless device determining signal strength of the packet received via the wireless channel. The processing then continues when the targeted and/or transmitting device determines the adequacy of the 1st power level based on the determined signal strength. If the 1st power level is adequate, the transmitting wireless device continues to transmit information at the 1st power level. If, however, the 1st power level is not adequate, the transmitting communication device adjusts its transmit power up or down to provide an adequate power level.

摘要： A method for feeding back transmitter beamforming information from a receiving wireless communication device to a transmitting wireless communication device includes a receiving wireless communication device receiving a preamble sequence from the transmitting wireless device. The receiving wireless device estimates a channel response based upon the preamble sequence and then determines an estimated transmitter beamforming unitary matrix based upon the channel response and a receiver beamforming unitary matrix. The receiving wireless device then decomposes the estimated transmitter beamforming unitary matrix to produce the transmitter beamforming information and then wirelessly sends the transmitter beamforming information to the transmitting wireless device.

摘要： Aspects of a method and system for coexistence between 20 MHz and 40 MHz OBSSes in WLANs. Aspects of a system may include a receiving device, such as a WLAN station (STA), which enables reception of an information frame, such as a management frame, via a wireless communication medium. The receiving device may be associated with a wireless network device group, such as a basic service set (BSS). The information frame received by the receiving device may transmitted by a transmitting device, such as a transmitting access point (AP), which is associated with a foreign wireless network device group, for example a foreign BSS. The receiving device may be reconfigured to restrict RF channel bandwidth utilized for transmitting and/or receiving signals via the wireless communication medium based on the received information frame.

摘要： A method and apparatus for accessing, controlling and utilizing a network communication medium. Various aspects of the present invention may comprise a first networked device with power-save capability. The first networked device may acquire control of a communication medium utilizing a medium access protocol, which may be contention-based. The first networked device may utilize the communication medium to communicate information to a second networked device. The first networked device may transfer control of the communication medium to the second networked device, whereby the second networked device may control the communication medium without having to acquire control of the communication medium by utilizing the medium access protocol. The second networked device may utilize the communication medium to communicate information to the first networked device while maintaining control over the communication medium. The second networked device may have buffered such information for delayed delivery to the first networked device.
