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.

Dynamic measurement periods in wireless communications

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.
