A communication system is disclosed in which a communication device transmits, to a base station and using communication resources that may be used for grant-free uplink communications, uplink data and information from which the communication device can be identified, wherein the information from which the communication device can be identified comprises a Cyclic Redundancy Check (CRC) value that is encoded with identity information identifying the communication device (for example, a C-RNTI of the communication device).

Communication system

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.

Communication system with beam quality measurement

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.

Apparatus and methods for communicating control resource set data

A communication system is disclosed in which a base station communicates with user equipment via an associated cell having a system bandwidth. The system bandwidth comprises a bandwidth part having a set of contiguous physical resource blocks. The base station initiates a random access procedure with the user equipment; provides first information identifying a set of frequency resources for an uplink channel; and provides second information identifying at least one specific frequency resource, within said set of frequency resources, for said uplink communication. The first information is provided prior to completion of the random access procedure.

A communication system is disclosed which a base station configures a user equipment (UE) to carry out measurements of signals transmitted in a plurality of neighbour cells and to transmit a measurement report. The UE performs the signal measurements and transmits the measurement report, which comprises the measurement results for at least one neighbour cell and further includes, for at least one reported neighbour cell, an associated unique cell identifier together with the corresponding measurement. The base station identifies a corresponding neighbour cell, from among a plurality of neighbour cells, based on the reported unique cell identifier, and triggers a communication procedure involving the UE and that neighbour cell.

Determining handover target cell among neighbour cells based on measurement report and cell identifier

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.
