Classification: CPC H | IPC H

Claim 14:
15. A communications device for transmitting data to or receiving data from a wireless communications network, the communications device comprising
transmitter circuitry configured to transmit signals via a wireless access interface provided by the wireless communications network,
receiver circuitry configured to receive signals transmitted via the wireless access interface, and
controller circuitry configured to control the transmitter circuitry and the receiver circuitry to transmit or to receive the signals, the control circuitry being configured to control the receiver circuitry to
detect a plurality of beams of radio signals each being transmitted periodically according to a time divided structure of the wireless access interface provided by the wireless communications network in different spatial directions,
select a first of the plurality of beams of radio signals for detecting a first version of a synchronisation signal transmitted with the first beam of radio signals,
select a second of the plurality of beams of radio signals for detecting a second version of the synchronisation signal transmitted with the second beam of radio signals,
synchronise the transmitter circuitry and the receiver circuitry with the time divided structure of the wireless access interface from at least one of the first version of the synchronisation signal and the second version of the synchronisation signal, and
select one of the first beam or the second beam from which to receive data transmitted via the wireless access interface or to transmit data via the wireless access interface on a first uplink beam paired with the first beam or a second uplink beam paired with the second beam.
