Abstract: An antenna system for a moving vehicle, the antenna system comprising: a main antenna to generate a main beam; a measurement antenna to generate a measurement beam; and control circuitry to perform an adjustment process by: rotating the main beam to an initial bearing angle; rotating the measurement beam independently of the main beam to receive signals at positions to either side of the initial bearing angle; comparing at least one metric measured for the signals received by the measurement antenna at the positions to either side of the initial bearing angle to generate a comparison output; and determining, based on the comparison output, a correction to be applied to the initial bearing angle of the main beam.

Abstract: A base station for wireless communication is provided. The base station including communication circuitry configured to, during transmission time slots, transmit downlink data for reception by terminals, and configured to, during reception time slots, receive uplink data transmitted by the terminals. Downlink scheduling circuitry determines, for each transmission time slot, downlink data allocations, each identifying a terminal to which downlink data is to be transmitted, and wireless communication resources to be used by the wireless communication circuitry to transmit the downlink data to the identified terminal. Uplink scheduling circuitry determines a candidate list of uplink data allocations identifying, for reception time slots, terminals to be allocated to transmit uplink data within the reception time slots and, for each identified terminal, the wireless communication resources to be used.

Abstract: A base station for wireless communication with a plurality of terminals and a method of operating a base station are described. The base station comprises downlink scheduling circuitry to perform a downlink scheduling process and uplink scheduling circuitry to perform a corresponding uplink scheduling process, the uplink scheduling process being constrained based on results of the downlink scheduling process. In addition, the uplink scheduling circuitry is configured to provide, to the downlink scheduling circuitry, a control signal to influence the downlink scheduling process.

Abstract: There is provided an apparatus and method for use with a moving vehicle. The apparatus comprises antenna circuitry for communicating with a main cell using an antenna configuration. Configuration circuitry performs an analysis process in which the antenna configuration is changed to communicate with and create a measurement of each of a plurality of candidate cells including the main cell, and to provide a result of the analysis process to the main cell. Control circuitry causes the configuration circuitry to perform the analysis process with a predetermined period. The control circuitry is configured to dynamically change the predetermined period based on at least one characteristic of a received signal of the main cell.
