摘要： Methods, devices and systems for allocating spectrum in a wireless local area network. A bit representation of the availability or unavailability of a plurality of sub-bands of a portion of frequency spectrum is generated and included in a physical layer protocol data unit, which is transmitted to a target station to allocate resource units within the portion of frequency spectrum for use by the target station. The sub-bands may be 20 MHz spectrum sub-bands for large-size resource units, or the portion of frequency spectrum may be a single 20 MHz band sub-divided into multiple sub-bands for allocating small-size resource units. A station that receives the data unit may decode the bit representation and use the allocated resource units to communicate over the wireless local area network.

摘要： An association beamforming training (A-BFT) method between an access point communicatively coupleable to a plurality of stations through a plurality of channels is described. The method includes: receiving a first sector sweep (SSW) frame from a first station on a first channel; receiving a second SSW frame from a second station on a second channel; processing the first and second SSW frames to determine corresponding first and second sector sweep feedback (SSW-feedback) frames; and transmitting the first and second SSW-feedback frames to the first and second stations, respectively, wherein the second SSW frame may be orthogonal to the first SSW frame, and wherein the first SSW frame may be spread using a first spreading sequence, the second SSW frame may be spread using a second spreading sequence, and wherein the first and second spreading sequences are mutually orthogonal.

摘要： An aspect of the disclosure provides a wireless frame transmission method. Such a method includes duplicating a preamble in the frequency domain to form at least one duplicate preamble, each preamble having multiple fields. The method further includes puncturing at least one of the preamble fields in the preamble with a first puncturing pattern and puncturing corresponding preamble fields in the at least one duplicate preamble with at least one additional puncturing pattern. The method further includes transmitting a frame including the preamble, the at least one duplicate preamble and a payload. In some embodiments the preamble and the duplicate preambles are each at different frequencies.

摘要： Transmitting, in a wireless local area network (WLAN), a second punctured coded bit sequence generated by puncturing coded data using a second puncturing pattern, wherein the coded data has previously been punctured using a first puncturing pattern to generate a first punctured coded bit sequence transmitted in the WLAN. The second puncturing pattern is different than the first puncturing pattern to cause at least some bits of the coded data that were omitted in the first punctured coded bit sequence to be included in the second punctured coded bit sequence.

摘要： A method and apparatus for authenticating a directional multi gigabit device for communication in an IEEE 802.11-compliant wireless network are provided. Network association and authentication can be performed in parallel, with association and authentication information elements included in common frames. Authentication information elements are included in at least one and potentially a sequence of management frames transmitted between an access point of the wireless network and the device. The authentication information elements are thereby exchanged between the access point and the device. The exchanged authentication information elements are used to establish that both the access point and the device possess a common cryptographic key. The exchanged management frames can also facilitate network association. Authentication information elements can also be included in non-management frames. A format for the authentication information elements is presented.
