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 disclosed in which a base station apparatus obtains information identifying a total integrity protected uplink data rate for a user equipment (UE), allocates a portion of the total integrity protected uplink data rate to a secondary node (SN), and notifies the UE about the portion allocated to the SN.

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 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.

Abstract: 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.
