Abstract:
Un procedimiento de sincronización de un aparato de comunicación inalámbrica (202), comprendiendo el procedimiento: la recepción de uno o más mensajes de sincronización (500), teniendo cada mensaje de sincronización información de temporización (514) y un identificador de grupo (510), comprendiendo la información de temporización información de temporización de anclaje, siendo el identificador de grupo el mismo valor que un identificador de grupo del aparato; la determinación de si una diferencia entre un valor temporal cuando un nodo de transmisión actualizó por última vez la información de temporización de anclaje y un valor temporal mantenido por el aparato es superior a un umbral; la actualización selectiva de un valor temporal del aparato inalámbrico basándose en la información de temporización en los uno o más mensajes de sincronización recibidos, en el que la actualización selectiva del valor temporal del aparato de comunicación inalámbrica comprende: la actualización del valor temporal con un valor temporal de un mensaje de sincronización recibido con un valor de preferencia maestro mayor que los valores de preferencia maestros de los otros uno o más mensajes de sincronización recibidos; la actualización del valor temporal con un valor temporal en la información de temporización de un mensaje de sincronización recibido con la información de temporización de anclaje más reciente entre los uno o más mensajes de sincronización recibidos; el descarte del mensaje de sincronización recibido si la diferencia supera el umbral.
Abstract:
Methods, systems, and devices are described for wireless communication. In one aspect, a method of wireless communication includes determining a transmit time metric associated with each transmission group of a number of transmission groups based at least in part on an amount of data in a transmit queue and a modulation and coding scheme (MCS) data rate for at least one wireless communication device in the transmission group. The method also includes scheduling a transmission to a first transmission group of the number of transmission groups based at least in part on the transmit time metric for the first transmission group.
Abstract:
This disclosure describes techniques operating a client device to com¬ municate with a wireless access point. The client device may awake from a low power mode of operation (401) receive a first portion of a beacon (402) from the access point that includes a delivery traffic identification (DTIM) message (403 404). According to the techniques described herein the client device may determine based on the DTIM message whether or not one or more packets of data are forthcoming from the access point (405). If one or more packets of data are forth¬ coming from the access point the client device may remain in an ac¬ tive mode of operation to receive the forthcoming packets (and/or a second portion of the beacon) (406). However if no packets of data are forthcoming from the access point the client device may return to the low power mode of operation before receiving and/or processing the second portion of the beacon (408).
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:
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.
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 creating a shortened network identifier having a first length from a full network identifier having a second length. The first length is shorter than the second length. The method further includes generating a compressed beacon including the shortened network identifier. The method further includes transmitting, at an access point, the compressed beacon.
