摘要： Systems, apparatuses and methods described herein provide a method for padding a signal extension of orthogonal frequency-division multiplexing (OFDM) symbols. A transceiver may obtain a plurality of data symbols for transmission, and determine that a number of information bits for a last symbol of the plurality of data symbols is not an integer value. A special padding rule may be applied to add padding bits to the last symbol. A number of coded bits for the last symbol may be determined when the number of information bits for the last symbol has changed, and the plurality of data symbols for data transmission may be encoded based on the determined number of coded bits for the last symbol.

摘要： In a method of generating a field of a physical layer (PHY) header of a data unit, bits to be included in the field are generated and the bits are duplicated to generate duplicated bits. First modulation data is generated based on the duplicated bits. The first modulation data corresponds to a first set of orthogonal frequency domain multiplexing (OFDM) sub-carriers corresponding to a first frequency band. Second modulation data is generated using the first modulation data. The second modulation data corresponds to a second set of OFDM sub-carriers corresponding to a second frequency band. One or more signals i) that span the first frequency band and the second frequency band and ii) that correspond to field of the PHY header are generated. Generating the one or more signals includes performing a frequency domain to time domain conversion based on the first modulation data and the second modulation data.

摘要： A wireless communication system and method uses a spatial spreading matrix to distribute the encoded spatial data streams to a number of transmit chains and further uses the spatial spreading matrix for antenna selection computation in a transmitter. The spatial spreading matrix is designed such that a receiver is able to know and utilize the spatial spreading matrix for computing transmission antenna selection, receiver antenna selection and joint transmission/receiving antenna selection. The use of this spatial spreading matrix for antenna selection computation provides increased accuracy in antenna selection for transmission of spatial data streams, where the number of spatial data streams is less than the number of transmit or receive chains between the transmitter and receiver, and the number of transmit or receive chains is less than the corresponding transmission or receiving antennas.

摘要： A communication device sets a first channel access timer to a first duration in which at least a first portion of a communication channel is expected to be busy, the first timer corresponding to a first one of a plurality of component channels of the communication channel. The communication device also sets a second channel access timer to a second duration in which at least a second portion of the communication channel is expected to be busy, the second timer corresponding to a second one of the plurality of component channels. The communication device counts down the first timer and the second timer. When at least one of the first timer and the second timer reaches zero, the communication device determines whether one or more of the component channels are idle, and transmits at least one signal in at least one of the component channels determined to be idle.

摘要： Embodiments described herein provide a method for fragmenting and reassembling data frames on a medium access control (MAC) layer in a wireless local area network. A datagram is received from an application running on a first network device, for transmission over a wireless communication link in the wireless local area network. A negotiation request is initiated with a second network device for determining whether both the first network device and the second network device have enhanced directional multi-gigabit capability (EMDG) for data segmentation and reassembly. When both devices have EMDG capability and the size of the datagram exceeds the maximum size defined by the wireless local area network transmission protocol, the datagram is segmented into a plurality of transmission data units on the MAC layer.
