Title: COMMUNICATIONS DEVICE AND METHOD
Abstract:
A communications device is configured to detect one or more beams of signals transmitted by each of a plurality of infrastructure equipment forming a plurality of cells of the wireless communications network, each of the beams transmitted from each of the infrastructure equipment being separately identifiable and forming a directional bias with respect to a location of the infrastructure equipment in which the signals can be received. The communications device is further configured to perform measurements for evaluating a quality of the plurality of cells consisting of one or more beams belonging to one or more of the plurality of infrastructure equipment on signals received from each of the detected beams, to determine from the evaluation of each of the cells whether one or more of the cells satisfies predetermined conditions, and if one or more of the cells satisfies the predetermined conditions to perform a process for identifying one or more of the cells which should be used by the communications device for transmitting data to or receiving data from the infrastructure equipment. The communications device is configured to determine, from the evaluation of each of the cells whether one or more of the cells satisfies predetermined conditions, by determining a number of the detected beams for receiving signals from each of the cells, and adapting one or both of the predetermined conditions or the evaluation of each of the cells in accordance with the determined number of the detected beams for receiving signals from the same cell to bias the predetermined conditions in accordance with the determined number of the detected beams. The communications device can be configured therefore to consider a number of beams provided by each cell and/or a quality of the beams as part of a process for identifying the cell via which the communications device should transmit or receive data.
