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： LDPC coding systems for 60 GHz millimeter wave based physical layer extension. LDPC (Low Density Parity Check) encoding in cooperation with sub-carrier interleaving, in the context of orthogonal frequency division multiplexing (OFDM), and appropriate symbol mapping is performed in accordance with transmit processing as may be performed within a communication device. In a receiving communication device, receive processing may be performed on a received signal based on the type of LDPC, sub-carrier interleaving, and symbol mapping thereof. The LDPC code employed in accordance with such LDPC encoding may have a partial-tree like structure. In addition, appropriate manipulation of the bits assigned to respective sub-carriers may be performed to ensure that the bits emplaced in the MSB (Most Significant Bit) location of various symbols has some desired diversity (e.g., from different codewords, from appropriately different locations within a given codeword, etc.).
