摘要： A system includes a temporal key module, a nonce module, and a security module. The temporal key module is configured to generate a first temporal key. The first temporal key is to be used to encrypt a plurality of packets. The nonce module is configured to generate a nonce for each packet encrypted based on the first temporal key. Each nonce includes a packet number that is different than packet numbers associated with other nonces generated by the nonce module. The security module is configured to determine when the packet number included in the nonce generated by the nonce module is greater than or equal to a predetermined threshold.

摘要： In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, the PHY data unit is generated according to a first PHY format when the PHY data unit is to be transmitted in a regular mode, wherein the first PHY format corresponds to a first bandwidth. The PHY data unit is generated according to a second PHY format when the PHY data unit is to be transmitted in an extended range mode, wherein the second PHY format corresponds to a second bandwidth. A preamble of the PHY data unit is modulated such that a receiving device can auto-detect whether the PHY data unit was transmitted at the first bandwidth or the second bandwidth.

摘要： A system includes a medium access control device receiving data for N of M stations transmitted from an access point to the N stations. A multicast module determines whether the received data includes first data, and to which grouping(s) of the M stations the access point is to transmit the first data. A unicast module determines whether the received data includes second data, and to which ones of the N stations the access point is to transmit the second data. A bitmap module generates a PVB including a first identifier for the grouping(s) of the M stations and second identifiers for the ones of the N stations. A segmentation module generates segmentation information indicating whether to divide the PVB into fragments. A message control module transmits a TIM indicating bit states of the first identifier and the second identifiers to ones of the N stations based on the segmentation information.

摘要： A method of generating packets for transmission in a wireless communication system, wherein each packet includes a SIG field that includes a first SIG subfield, includes generating a data packet and a null data packet. Generating the data packet includes generating information bits of the first SIG subfield of the data packet and generating the data portion of the data packet. The information bits of the first SIG subfield of the data packet indicate, to a receiving device, a length corresponding to a data portion of the data packet. Generating the null data packet includes generating information bits of the first SIG subfield of the null data packet. The information bits of the first SIG subfield of the null data packet indicate, to a receiving device, a first physical layer (PHY) parameter value associated with the null data packet. The first PHY parameter value is not a length value.
