Abstract
A method of transmitting data to a communications device from a wireless communications network comprising one or more infrastructure equipment, the method comprises configuring one or more of the infrastructure equipment for transmitting one or more candidate beams of signals which can be used to transmit the data to the communications device from each of one or more cells of the wireless communications device formed by the infrastructure equipment. Each of the candidate beams is configured with a different directional bias with respect to a location of the one or more cells from which the signals of the candidate beam can be received when transmitted.
Claims20
A communications device, comprising:
- circuitry configured to
- transmit signals to an infrastructure equipment of a wireless communications network via a wireless access interface provided by the infrastructure equipment;
- receive signals from the infrastructure equipment via the wireless access interface;
- form a set of beams, from which data is received from the wireless communications network, from a plurality of candidate beams of signals to receive data transmitted by the infrastructure equipment from one or more of the cells of the wireless communications network or to transmit data to the one or more cells, wherein each candidate beam of the plurality of candidate beams has a directional bias with respect to a location of a cell from which signals of the candidate beam are received or transmitted, and the set of beams comprises one or more serving beams and one or more fallback beams;
- and
- switch a fallback beam of the one or more fallback beams to be one of the one or more serving beams.
An infrastructure equipment, the infrastructure equipment comprising:
- circuitry configured to
- transmit signals to a communications device via a wireless access interface which forms a cell of a wireless communications network;
- receive signals from the communications device via the wireless access interface;
- transmit one or more candidate beams of signals to transmit data to the communications device, or receive the one or more candidate beams of signals to receive the data from the communications device, wherein each candidate beam of the one or more candidate beams has a directional bias with respect to a location of a cell from which the signals of the candidate beam are received or transmitted;
- and
- determine whether each candidate beam of the one or more candidate beams is to form one or more serving beams or one or more fallback beams, with which the data can be transmitted or received from the communications device.
A transmission method, comprising:
- transmitting signals to a communications device via a wireless access interface which forms a cell of a wireless communications network;
- receiving signals from the communications device via the wireless access interface;
- transmitting one or more candidate beams of signals to transmit data to the communications device, or receive the one or more candidate beams of signals to receive the data from the communications device, wherein each candidate beam of the one or more candidate beams has a directional bias with respect to a location of a cell from which the signals of the candidate beam are received or transmitted;
- and
- determining whether each candidate beam of the one or more candidate beams is to form one or more serving beams or one or more fallback beams, with which the data can be transmitted or received from the communications device.
