Abstract:
A station (STA) comprising: a transmitter configured to transmit information to an access point (AP); a receiver configured to receive, from the AP, a management frame that includes an indication of an assigned group; wherein the transmitter is further configured to transmit, to the AP, an acknowledgement associated with the management frame; wherein the receiver is further configured to receive a data frame, wherein the data frame comprises a data packet and a group identifier; and a processor configured to determine whether the group identifier received in the data frame corresponds to the assigned group, and wherein the processor is further configured to cause the STA to enter a power saving mode on a condition that the group identifier received in the data frame does not correspond to the assigned group.
Abstract:
The present invention is directed to methods and wireless communication devices that are configured to enhance communication capacity in a wireless network. In one aspect of the invention various scheduling processes and schedulers (40) for the transmissions of data packets (46) are disclosed. In another aspect of the invention, the selection of appropriate transmission rates to advertise by a common unit which provides wireless service to different types of wireless transmit receive units WTRUs is addressed.
Abstract:
A method and system for wireless mobile unit communication within a wireless network having geographic areas for preferred communication usage is provided. An estimated geographic location of a mobile unit is determined. The mobile unit is provided with relative position data of at least one preferred communication area relative to the determined mobile unit estimated location. The mobile unit is then relocated to a preferred communication area based on the relative position data. Preferably, a request for a pre-designated preferred communication area location is initiated by a mobile unit transmission and received by a network base station. The mobile unit can be equipped with a global positioning system (GPS) to determine the mobile unit's estimated location. Transmission of estimated location data can be dependent upon whether the mobile unit or the network calculates relative position data.
Abstract:
A peer-to-peer communication system using a direct link setup (DLS) is disclosed. A mobile station (STA) establishes a direct communication link with another STA by sending a message requesting a DLS to an access point (AP), (i.e., a centralized controller). The AP may accept or reject the DLS request based on channel measurements. If the DLS request is accepted, the DLS is established such that the STAs may directly communicate with each other. An established DLS connection may be torn down by the AP sending a message including a DLS teardown request to one of the STAs, or based on channel measurements. The system may be an Ad hoc network comprising a plurality of STAs without an AP where each STA maintains a database of one-hop and two-hop STAs, and establishes a direct link to other STAs after informing neighboring STAs of an intention to establish a direct communication link.
Abstract:
A method and apparatus for selecting one of a plurality of multi-band access points (APs) to associate with a multi-band wireless transmit/receive unit (WTRU) are disclosed. The multi-band APs broadcast frequency band information regarding multiple frequency bands on which the multi-band AP is configured to operate. The multi-band WTRU selects a particular multi-band AP to associate with and a frequency band to use to communicate with the selected multi-band AP based on the frequency band information. If the multi-band WTRU receives frequency band information from the selected multi-band AP which indicates that a characteristic, (e.g., throughput, path loss, load, capacity, backhaul), of the selected frequency band is unacceptable, the multi-band WTRU determines whether to disassociate with the selected multi-band AP or to continue to associate with the selected multi-band AP via a different frequency band.
Abstract:
Un método para unidades inalámbricas transmisoras/receptoras, WTRU, comprendiendo el método: que la WTRU reciba desde un Nodo B evolucionado (eNB) una primera asignación, siendo la primera asignación una asignación de un canal de control de enlace ascendente no sujeto a disputa, NCB, comprendiendo la primera asignación una configuración para transmitir solicitudes de planificación (SP) por el canal NCB de control de enlace ascendente, e indicando la configuración una periodicidad en la que los recursos físicos del canal NCB de control de enlace ascendente están dedicados a la WTRU para transmitir SP; transmitir una solicitud de planificación por el canal NCB de control de enlace ascendente según la primera asignación; que la WTRU monitorice un canal de control de enlace descendente; que la WTRU detecte que una transmisión por el canal de control de enlace descendente está prevista para la WTRU en función de un identificador de WTRU indicado en la transmisión por el canal de control de enlace descendente, comprendiendo la transmisión por el canal de control de enlace descendente una segunda asignación, siendo la segunda asignación una asignación de un canal compartido de enlace ascendente; y que la WTRU transmita datos por el canal compartido de enlace ascendente según la segunda asignación.
