1. A receiving communications device comprising
a receiver configured to receive signals from one or more of a plurality of other communications devices within sidelink communications resources of a plurality of instances of a resource pool of a sidelink interface, the resource pool being formed of a plurality of time-divided slots and a plurality of frequency-divided regions, and
a controller configured in combination with the receiver
to monitor for one or more first current signals transmitted by at least a first transmitting communications device of the other communications devices to the receiving communications device in a first subset of the time-divided slots and the frequency-divided regions of the resource pool during a first of the resource pool instances,
wherein the first subset is dependent on which of the time-divided slots and the frequency-divided regions of the resource pool in which one or more first previous signals were received by the receiving communications device from the first transmitting communications device during a second of the resource pool instances during which the receiving communications device is configured to monitor a larger number of the time-divided slots of the resource pool than in the first subset and/or a larger number of the frequency-divided regions of the resource pool than in the first subset, wherein the second resource pool instance is a preceding resource pool instance to the first resource pool instance.
