Abstract: Certain aspects of the present disclosure provide methods and apparatus for secure transmission of packets with short headers. The methods may include temporarily suspending the use of packets that use a short MAC header (that lack a Key ID field) during re-keying procedures and resuming the use of such packets after a new default Key ID is established via the re-keying procedures.

Abstract: A first wireless station provides a configuration indication value that specifies a maximum number of medium access control layer service data units (MSDUs) that may be included in each medium access control layer protocol data unit (MPDU), or in each aggregated MPDU (A-MPDU), received by the first wireless station. A second wireless station receives the configuration indication value from the first wireless station, and in response, transmits only MSDUs (or A-MSDUs) having no more than the specified maximum number of MSDUs to the first wireless station. The configuration indication value can be included in various elements transmitted between the first and second wireless stations, including for example, a high throughput (HT) capabilities element, a very high throughput (VHT) capabilities information field, a VHT operation element or an add block acknowledge (ADDBA) response frame.

Abstract: Methods, systems, and devices are described for selectively enabling legacy protection in a WLAN. A method may include receiving, by an access point, a DSSS signal from a station, and activating legacy protection within a WLAN of the access point based at least in part on the received DSSS signal. For instance when a station cannot be initially detected, the access point may transmit an OFDM signal indicating a NAV period associated with a remote station initial access period. The access point may then receive a DSSS transmission from a remote station during the remote station initial access period. A method may include receiving, at a wireless station, an indication of a NAV period associated with remote station initial access, monitoring for radio transmissions during the NAV period, and transmitting a DSSS signal during the NAV period based on the monitoring.
