Abstract:
Methods, devices, and computer program products for improving training field design in packets with increased symbol durations are disclosed. In one aspect, a method of transmitting a packet on a wireless communication network is disclosed. The method includes transmitting a preamble of the packet over one or more space-time-streams, the preamble including one or more training fields configured to be used for channel estimation, the one or more training fields each comprising one or more symbols of a first symbol duration. The method further includes transmitting a payload of the packet over the one or more space-time-streams, the payload comprising one or more symbols of a second symbol duration, the second symbol duration greater than the first symbol duration.
Abstract:
Peer to peer direct mode connection is either time or frequency multiplexed with traffic towards an AP. One peer requests a first time or a first frequency for transmitting to a peer. Once the request is accorded and the direct traffic mode is carried out with the peer, in a second time or in a different frequency, further traffic is carried out by the peers with the AP.
Abstract:
Methods and apparatuses are proposed for supporting one or more user-dependent channel state information (CSI) feedback rates in a downlink spatial division multiple access (SDMA) system. For certain aspects, an access point (AP) may receive a channel evolution feedback from one or more stations and send a request for CSI to the stations whose CSI values need to be updated. For certain aspects, the AP may poll the stations for updated CSI values. For certain aspects, deterministic back-off timers may be assigned to the stations indicating when to send their CSI feedback. The proposed methods may improve system performance.
Abstract:
Se proporcionan métodos y aparatos para el enlace ascendente de múltiples usuarios. En un aspecto, se proporciona un método para la comunicación inalámbrica. El método incluye la transmisión de un mensaje de listo para transmitir (CTX) a dos o más estaciones, indicando el CTX una oportunidad de transmisión ascendente, comprendiendo además el mensaje CTX una solicitud de que las dos o más estaciones transmitan simultáneamente datos ascendentes en un momento específico. El método incluye además la recepción de una pluralidad de datos ascendentes desde al menos dos estaciones en el momento específico. (Traducción automática con Google Translate, sin valor legal)
