[Object] To make it possible to select a cell that is more preferable for a terminal device in an environment in which beamforming is performed. [Solution] There is provided a device including: an acquiring unit configured to acquire received quality information indicating received quality of a reference signal in a terminal device; and a control unit configured to perform cell selection for the terminal device based on the received quality information. When a predetermined condition related to use of weight sets for beamforming by a base station is satisfied, the control unit does not perform the selection based on the received quality information.

The invention provides a method of controlling a mobile communication network, the method comprising, an uplink controlling entity, in response to reception quality measurement reports sent by a plurality of reception points within the mobile communication network following a transmission of data by a user equipment device, the reception quality measurement reports being responsive to the reception of the transmission, configuring the reception points within the mobile communication network such that each of the multiple reception points is configured to exhibit a participation behaviour with respect to at least one of subsequent measurement reporting and payload reporting with regard to transmissions from the user equipment device, the participation behaviour being dependent on the reception quality measurement report.

This application provides a data transmission method and apparatus. A terminal device sends first data to a network device in the n.sup.th time unit, where n is an integer greater than or equal to 0. The terminal device send second data to the network device when the terminal device does not receive the response message corresponding to the first data before the (n+k).sup.th time unit, wherein the second data is new data which is different from the first data, where k is a positive integer. According to the data transmission method provided in some embodiments of this application, the terminal device may flexibly determine the transmission mode of the second data based on an actual situation, so as to reduce a transmission delay of uplink data and improve transmission reliability of the uplink data.

A multi-user uplink transmission is performed by analyzing, by a first wireless station, a spatial reuse field in a first frame, and generating, by the first wireless station, a second frame, wherein the second frame includes a spatial reuse field that is generated based on the spatial reuse field of the first frame. The first frame and the second frame are within the same transmission opportunity (TXOP) and the first frame is transmitted prior to the second frame during the TXOP.
