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.

摘要： Embodiments described herein provide a method for resource unit signaling with reduced data bits in a wireless local area network. At a wireless transceiver, a data frame may be obtained for transmission. The data frame includes a first preamble portion and a second preamble portion compliant with a wireless local area network communication protocol. When an available resource unit for transmitting the data frame is less than an allowed bandwidth, the first preamble portion and the second preamble portion may be configured with resource unit signaling bits. When the available resource unit is greater than or equal to the allowed bandwidth, the resource unit may be virtually divided into a plurality of channels. At least one of the first preamble portion and the second preamble portion may be configured with a first number of bits representing a number of users spatially multiplexed on a channel from the plurality of channels.

摘要： In a method for reducing interference in wireless communications, a beamforming matrix is determined at a first communication device based on an estimate of a multiple input, multiple output (MIMO) communication channel between the first communication device and a second communication device. Both the first communication device and the second communication device belong to a first wireless network. Alternatively, the beamforming matrix may be generated based on the estimate of the MIMO communication channel and received at the first communication device. The beamforming matrix is used at the first communication device for the purpose of reducing interference to a second wireless network, where the interference is caused by the first communication device transmitting to the second communication device via the MIMO communication channel.

摘要： In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, information bits to be included in the PHY data unit are received. A number of padding bits are added to the information bits. The number of padding bits is determined based on respective virtual values of each of one or more encoding parameters. The information bits are parsed to a number of encoders and are encoded, using the number of encoders, to generate coded bits. The coded bits are padded such that padded coded bits correspond to respective true values of each of the one or more encoding parameters. The PHY data unit is generated to include the padded coded bits.

摘要： A method for generating OFDM signals is implemented in a device operating according to a communication protocol. The protocol defines non-duplicate mode data units corresponding to single component channels of a BSS channel, and non-duplicate mode data units corresponding to sets of adjacent component channels. Non-duplicate mode data units corresponding to a set of component channels have more lower-edge and/or upper-edge guard tones than non-duplicate mode data units corresponding to single component channels. The method includes determining that a duplicate mode will be utilized for an OFDM transmission in the set of component channels and, in response, generating a duplicate mode data unit. The duplicate mode data unit has fewer lower- edge and/or upper-edge guard tones than a non-duplicate mode data unit corresponding to a set of component channels, and includes one duplicate of the non-duplicate mode data unit corresponding to the single component channel for each adjacent component channel.
