摘要： Aspects of a method and system for utilizing Givens rotation expressions for asymmetric beamforming matrices in explicit feedback information are presented. In one aspect of the invention, Givens matrices may be utilized to reduce a quantity of information communicated in explicit feedback information via an uplink RF channel. The explicit feedback information may include specifications for a feedback beamforming matrix that may be utilized when transmitting signals via a corresponding downlink RF channel. The feedback beamforming matrix may represent a rotated version of an un-rotated matrix. The Givens matrices may be utilized to apply one or more Givens rotations to un-rotated matrix. The feedback beamforming matrix may be computed based on a matrix product of a plurality of Givens matrices. The feedback beamforming matrix may be encoded utilizing fewer bits than may be required to encode the un-rotated matrix.

摘要： Distributed signal field for communications within multiple user, multiple access, and/or MIMO wireless communications. In accordance with wireless communications, a signal (SIG) field employed within such packets is distributed or partitioned into at least two separate signal fields (e.g., SIG A and SIG B) that are located in different portions of the packet. A first of the SIG fields includes information that may be processed and decoded by all wireless communication devices, and a second of the SIG fields includes information that is specific to one or more particular wireless communication devices (e.g., a specific wireless communication device or a specific subset of the wireless communication devices). The precise locations of the at least first and second SIG fields within a packet may be varied, including placing a second of the SIG fields (e.g., including user-specific information) adjacent to and preceding a data field in the packet.

摘要： Management frame map directed operational parameters within multiple user, multiple access, and/or MIMO wireless communications. A management frame map may be generated within and transmitted from a first wireless communication device to a number of other wireless communication devices. Thereafter, certain subsequently transmitted packets may be analyzed and processed by the receiving wireless communication devices based on that earlier received management frame map. One or more operational parameters are determined for a subsequently transmitted packet based on the previously received management frame map; such operational parameters then govern the manner in which at least a portion of the subsequently transmitted packet is processed. Some examples of such operational parameters include a cluster on which a least a portion of the packet is transmitted, a modulation coding scheme (MCS), a forward error correction (FEC) coding scheme, space time block coding (STBC), an antenna configuration within the wireless communication device, etc.

摘要： Management frame directed cluster assignment within multiple user, multiple access, and/or MIMO wireless communications. From a first wireless communication device, a management frame may be transmitted to a number of other wireless communication devices to assign respective clusters (i.e., cluster being one or more channels within one or more bands) for use in communications by those other wireless communication devices. The first wireless communication device may be an access point (AP), and the others may be wireless stations (STAs); alternatively, all of the wireless communication devices in the communication system (e.g., including the first wireless communication device) may be STAs. The cluster assignment may be modified for any of a number of various reasons (e.g., periodically, after a certain number of packets being transmitted and/or received, communication system operating condition change, change in number, type, capabilities, etc. of the various wireless communication devices in the communication system, etc.).
