摘要： In a method of determining an available channel bandwidth in a communication system, wherein the communication system utilizes i) a set of component channels for transmitting data streams and ii) a set of access control channels, and wherein each of at least some of the access control channels partially overlaps, in frequency, at least one of the component channels, whether a primary channel of the access control channels is idle is determined. The primary channel partially overlaps, in frequency, at least a first one of the component channels. That a composite channel includes one or more of the component channels is determined based at least on a determination of whether the primary channel is idle. A signal is caused to be transmitted via the composite channel after determining that the composite channel includes one or more of the component channels.

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.
