摘要： A communication device determines that simultaneous transmission and reception via multiple frequency segments in a WLAN is not permitted. The communication device transmits a first packet in a first frequency segment beginning at a first time, and transmits a second packet in a second frequency segment beginning at a second time that is different than the first time. Transmission of the second packet overlaps in time with transmission of the first packet. In response to having determined that simultaneous transmission and reception via multiple frequency segments is not permitted, the communication device includes in the first packet padding so that an end of transmission of the first packet occurs at a same time as an end of transmission of the second packet.

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： A communication device receives a plurality of information bits and determines a maximum number of information bits that can be encoded such that, after the plurality of information bits have been encoded using i) a forward error correction scheme, and ii) a block coding scheme, the block coded bits fit within a single orthogonal frequency division multiplex (OFDM) symbol. The maximum number of information bits is based on a number of repetitions of coded information bits by the block coding scheme, and a number of block coded bits for the maximum number of information bits is less than a number of data tones of the single OFDM symbol. The communication device encodes the plurality of information bits using the forward error correction scheme and the block coding scheme to generate block coded bits, and generates a physical layer data unit to include the block coded bits in the single OFDM symbol.

摘要： A first communication device generates a range measurement packet (or a packet that includes a probe response frame, a TIM frame, etc.) associated with a range measurement signal exchange session between the first communication device and a second communication device. The first communication device records a time value of a first timer corresponding to a time of transmission of the packet, and includes timing information corresponding to the recorded time value in the packet. The first communication device transmits the packet to the second communication device. The timing information in the packet is useable by a third communication device to adjust time values corresponding to a second timer, which the third communication device includes.

摘要： A communication device determines, in connection with a prior uplink multi- user (UL MU) communication in which the communication device participated, whether the communication device is to use one or more first channel access parameters, or one or more second channel access parameters for accessing a communication medium for a single user (SU) transmission by the communication device, where using the one or more first channel access parameters is associated with a greater probability of obtaining access to the communication medium as compared to using the one or more second channel access parameters. Depending on the determination made, the communication device uses the one or more first channel access parameters, or the one or more second channel access parameters to attempt to access the communication medium. In response to accessing the communication medium, the communication device transmits the SU transmission via the communication medium.
