    摘要: A method for wireless communications is disclosed that includes receiving a plurality of requests to transmit data from a plurality of apparatuses; determining resource allocation for a set of apparatuses in the plurality of apparatuses, wherein the determination is based on the plurality of requests; and transmitting a message comprising the resource allocation to the set of apparatuses to permit data transmission. Another method for wireless communications is disclosed that includes contending for access to a medium based on a request, by an apparatus, with a plurality of other apparatuses; receiving a message, the message comprising a resource allocation based on requests from the apparatus and the other apparatuses, wherein the resource allocation permits data transmission from the apparatus and some of the other apparatuses; and transmitting data by the apparatus based on the message. Apparatuses for performing the methods are also disclosed.

    摘要: Certain aspects of the present disclosure provide techniques and apparatus for managing group identifiers (IDs) in multiuser multiple-input multiple-output (MU-MIMO) schemes to ensure that the group ID maps to the same assigned spatial stream position for a particular station (STA), for either Direct Link Service (DLS) or downlink (DL) MU-MIMO transmissions. One example method generally includes transmitting, form a first apparatus to a second apparatus, a message requesting assignment of a group ID identifying a group of apparatuses for receiving MU transmissions; and receiving, from the second apparatus, an indication of the assigned group ID, such that spatial stream assignments for the group of apparatuses are the same between the first and second apparatuses, the spatial stream assignments corresponding to the assigned group ID.

    摘要: Simultaneous, multi-user uplink communication is scheduled in a wireless network by transmitting a poll message to a plurality of access terminals in response to receiving a first request to transmit data via uplink. The poll message includes a solicitation for requests to transmit data from each of the plurality of access terminals. The poll message also includes a medium reservation and schedule for transmission of the requests from the access terminals. Based on the requests received from the access terminals, a number of the access terminals are selected for simultaneous transmission of data via uplink. A transmit start message is sent to each of the selected access terminals indicating when and for how long the selected access terminals may transmit data via uplink. After the data is received, a block ACK message is sent to each of the selected access terminals indicating successful simultaneous communication.

    摘要: Transmission parameters are determined for communication between apparatuses. These transmission parameters may specify, for example, a number of spatial streams, a bandwidth, and a transmission rate. Based on the determined parameters, a table of a set of tables comprising transmission parameters is identified and an index from the table is determined. Rate information is then sent in a frame from one of the apparatuses to the other. The rate information comprises several fields indicative of the index, the number of spatial streams, and bandwidth. The apparatus that receives the rate information may then use this information to identify the table and obtain transmission parameters from the table.
