Abstract: A communication system is disclosed in which an NR radio access network (RAN) node identifies resources, that the NR RAN node is to use for transmissions, for protection from interference from another RAN node. The NR RAN node sends, to the other RAN node, information indicating the identified resources for protection from interference. The information indicating the identified resources comprises a list of parameters, typically including resource bitmaps, based on which the other RAN node is able to determine the resources for protection from interference.

Abstract: A communication system is disclosed in which a base station manages the transmission of on-demand system information to optimise the trade-off between the additional signalling overhead associated with on-demand transmission and the resource usage inefficiencies associated with the sometimes unnecessary transmission of system information on a periodic basis. The base station manages switching from on-demand transmission to periodic transmission, and vice versa, based on one or more utilisation thresholds.

Abstract: A method, performed by a communication device, including a) measuring a respective beam quality for each of a plurality of beams of a cell, b) identifying, within said plurality of beams, a first group of beams comprising a number, N, of beams, c) selecting, from within said first group of beams, a second group of beams comprising a number, M, of beams, and d) deriving a cell quality for the cell based on the measured beam qualities for the M beams of the second group.

Abstract: A system is disclosed in which an item of user equipment (UE) obtains a reference signal received power (RSRP) threshold value for transmitting a random access message (MsgA) comprising both a preamble part and a Physical Uplink Shared Channel (PUSCH) transmission part. The UE obtains information identifying at least one respective offset associated with at least one priority level, and determines a type of random access procedure (two-step or legacy random access procedure) to be performed based on an RSRP measured by the UE, the RSRP threshold value, and a priority level associated with the UE.

Abstract: A communication system is disclosed in which a base station serves a communication area, wherein the communication area is formed by a plurality of directional beams each covering a respective portion of the communication area and each having a different respective beam identifier. The base station communicates control information, for a communication device (UE), using at least one directional beam associated with that communication device (e.g. a UE-specific operational beam set).

Abstract: A communication system is disclosed in which a communication device and a base station initially communicate using a first bandwidth. The communication device monitors for control data transmitted, by the base station, using a first control resource set conveyed in the first bandwidth. The communication device and the base station switch to using a second bandwidth, wherein the second bandwidth is different to the first bandwidth, and the communication device monitors for control data transmitted, by the base station, using a second control resource set that is conveyed in the second bandwidth.

Abstract: A communication system is disclosed in which a home base station operates a home cell and a macro base station operates a macro cell. The home base operates a cell located at least partially within the macro cell. The home base station can obtain information identifying a quantity of home base stations that each operate at least one respective cell that is located at least partially within the macro cell and from this information, and further information identifying resource usage via said home base station, can set a target power for said home base station.
