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 method performed by a user equipment in a communication system is disclosed in which the user equipment communicates data with a base station using at least one data radio bearer (DRB). The data is communicated using a plurality of data flows that are mapped to a single DRB. Each data flow is configured to have a respective set of quality of service (QoS) characteristics specific to that data flow. The user equipment measures quality of experience (QoE) parameters for the data flows and reports QoE information to the base station based on the measurement of the QoE parameters.

Abstract: A system is disclosed in which a base station receives information indicating a cell category associated with a neighbour cell and stores the cell category information in a neighbour cell relation table. The base station May receive the cell category information from a UE, from an Access and Mobility Function, or from a base station operating the neighbour cell. The cell category information may indicate, amongst others, that the neighbour cell is a cell of a non-terrestrial network, a small cell, or an energy saving cell.

Abstract: A communication system is disclosed in which a user equipment (UE) communicate with a base station via a non-terrestrial network. The UE obtains information identifying a threshold associated with a timing advance value applicable for communications between the UE and the network node via the non-terrestrial network, acquires a timing advance value for said communications with the network node, and determines whether to transmit a timing advance report to the network node based on the timing advance value and the threshold.

Abstract: In one aspect, a method performed by a base station includes:
performing a Radio Resource Control (RRC) resume procedure for a user equipment (UE) in a cell of a non-public network; obtaining i) information identifying whether or not the UE is authorised to access the cell of a non-public network or ii) information identifying at least one non-public network that the UE is authorised to access, from another base station; verifying, based on the information of i) or ii), whether the UE is authorised to access the non-public network, wherein the information of i) or ii) is stored, in a UE context for the UE in the another base station in a process of a RRC setup for the UE in another cell of a network.-

Abstract: A communication system is disclosed in which a distributed base station apparatus comprises a central unit for control plane signalling (CU-CP), at least one a central unit for user plane signalling (CU-UP), and at least one distributed unit. The CU-CP obtains information indicating whether a security configuration is supported by a CU-UP and selects a security configuration for an item of user equipment (UE) based on the obtained information.

Abstract: A communication system is described in which a base station transmits, to a UE (user equipment), via a data radio bearer (DRB), a downlink data packet that includes information identifying a data flow. The downlink data packet is transmitted prior to commencement of transmission, via that DRB, of data packets comprising any downlink user-plane data associated with the identified data flow.
