Abstract: Systems and methods for formatting frames in neighborhood aware networks are described herein. One aspect of the subject matter described in the disclosure provides a method of communicating in a wireless neighborhood aware network (NAN). The method includes determining a discovery period. The method further includes generating a discovery window information element indicating a start time of a discovery window. The method further includes generating a NAN beacon or other sync frame comprising the discovery period and the discovery window information element. The method further includes transmitting, at a wireless device, the NAN beacon or other sync frame during the discovery window.

Abstract: A method of providing rate adaptation in a multi-user wireless communication system including single-user beamforming (SU-BF) and multi-user multiple-input multiple-output (MU-MIMO) is described. In this method, a master rate, which is a modulation and coding scheme (MCS) for the SU-BF, is determined. An MCS for each transmit mode is derived from the master rate using a rate mapping. Using the results from the mapping, the master rate, instead of the MCS for each transmit mode, is tracked. In one embodiment, a mapping calibration is periodically performed.

Abstract: Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network includes transmitting, at an access point, a full beacon at a first multiple of a beacon interval. The method further includes transmitting a compressed beacon at each beacon interval that is not the first multiple of the beacon interval. Another method of communicating in a wireless network includes receiving, at a wireless device, a full beacon at a first multiple of a beacon interval. The method further includes receiving a compressed beacon at a beacon interval that is not the first multiple of the beacon interval.
