    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.

    Abstract: Un dispositivo inalámbrico (112, 202) para monitorizar un número de dispositivos inalámbricos vecinos (114, 116, 118, ..., 138) en una red inalámbrica (100), en el que el dispositivo inalámbrico está configurado para: recibir un mensaje de uno de los dispositivos inalámbricos vecinos (114, 116, 118, ..., 138), comprendiendo el mensaje un identificador asociado con dicho uno de los dispositivos inalámbricos vecinos; añadir el identificador como una cadena de entrada en un filtro Bloom (600) que incluye una matriz de bits de un número entero de m bits y un número entero de k funciones resumen diferentes suministrando el identificador como una cadena de entrada a cada uno del número entero k de diferentes funciones resumen, en el que cada función hash aplica la cadena de entrada a una posición en una matriz del filtro Bloom, y estableciendo los bits en las posiciones de la matriz identificadas por las k diferentes funciones resumen en uno; y estimar el número de cadenas distintas que se han añadido al filtro Bloom (600) en base al número de unos o el número de ceros en el filtro Bloom (600) dividido por la longitud de la matriz, el número de cadenas distintas que representan una estimación del número de dispositivos inalámbricos vecinos (114, 116, 118, ..., 138) en la red inalámbrica (100).

    Abstract: Method, devices, and computer program products communicating discovery information in a wireless neighborhood aware network (NAN). One method includes receiving (1310), at a first wireless device, a massage from a neighboring wireless device. The message includes a data structure indicative of discovered device identifiers. The method further includes determining (1320) whether the data structure indicates an identifier of the first wireless device. The method further includes transmitting (1330) a message including the identifier of the first wireless device when the data structure does not indicate the identifier of the first wireless device.

    Abstract: CERTAIN ASPECTS OF THE PRESENT DISCLOSURE PROVIDE TECHNIQUES AND APPARATUS FOR SIGNALING THE BANDWIDTH TO BE USED FOR WIRELESS COMMUNICATIONS USING AN RTS/CTS (REQUEST TO SEND/CLEAR TO SEND) FRAME EXCHANGE, PROVIDING FOR BANDWIDTHS OF AT LEAST 20 MHZ, 40 MHZ, 80 MHZ, 160 MHZ, OR HIGHER. THIS EXCHANGE OF BANDWIDTH INFORMATION MAY BE PERFORMED IMPLICITLY-BY DETERMINING THE CHANNELS IN WHICH THE RTS/CTS FRAMES ARE ACTUALLY SENT-OR EXPLICITLY. IN ADDITION TO THIS BANDWIDTH INFORMATION EXCHANGE, ASPECTS OF THE PRESENT DISCLOSURE MAY ALSO ALLOW FOR NETWORK ALLOCATION VECTOR (NAV) PROTECTION IN MULTIPLE CHANNELS. IN THIS MANNER, THE WIRELESS MEDIUM MAY BE RESERVED, AND THE TRANSMISSION MAY BE PROTECTED FROM HIDDEN NODES. (FIGURE 6)
