Systems and Methods for Operation of Wireless User Devices with Cellular and Wi-Fi Interfaces

摘要

An embodiment method for wireless communication includes grouping a plurality of user equipments (UEs) wirelessly coupled to a cellular base station (BS) into a UE cluster to function as a Wi-Fi virtual station (V-STA), and communicating with an access point (AP) to contend for a Wi-Fi transmission opportunity (TXOP) for the V-STA. In a further embodiment, the cellular BS contends for the TXOP on behalf of the UE cluster using a carrier sense multiple access with collision avoidance (CSMA-CA) procedure. In an alternative embodiment, one UE in the UE cluster is selected as a leader UE to contend for the TXOP on behalf of the UE cluster using a CSMA-CA procedure.

主权项

1. A method for wireless communications by a first user equipment (UE) having a cellular air interface and a wireless-fidelity (Wi-Fi) air interface, the method comprising:
receiving, by the first UE, a cellular message from a base station (BS) instructing the UE to be a member of a UE cluster with at least one other UE; and transmitting, by the first UE, data to an access point (AP), synchronously with the UE cluster in accordance with cellular timing information, and in a virtual station (V-STA) transmit opportunity (TXOP).
