    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system Has RA been for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be Yes applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Described is a method of operating a mobile terminal in a wireless communications network, the mobile terminal being arranged to communicate with a base station, the method comprising: one or more of: determining a cause of the Random Access procedure initiation following initiation of a Random Access procedure; and determining one or more transmission priority factors indicating an operating parameter of the network; and based on one or more of the determined cause of Random Access procedure initiation and the determined one or more transmission priority factors, performing one of: prioritising Random Access signal transmission over signal transmission on the up-link shared channel; prioritising signal transmission on the uplink shared channel over Random Access signal transmission; or making no change to the existing signal transmission protocol. Also described is a method of operating a base station in in a wireless communications network, the base station being arranged to communicate with a mobile terminal, the method comprising determining a prioritisation action for the mobile terminal to perform based on one or more of a determined indication and a received indication from the mobile terminal. Also described is a method and apparatus for signalling for group handover or cell re-selection in non-terrestrial networks.

    Abstract: The disclosure relates to a method and apparatus for controlling packet duplication transmission in a wireless communication system. According to an embodiment of the disclosure, a method, performed by a user equipment (UE), of controlling packet duplication transmission in a wireless communication system includes: receiving a packet duplication configuration for a radio bearer, through a radio resource control (RRC) message, from a base station; determining whether each of a plurality of radio link control (RLC) entities is configured to be used for uplink packet duplication transmission; and performing, when packet duplication transmission is activated, packet duplication transmission by using a RLC entity set to be used for uplink packet duplication transmission.

    Abstract: There is disclosed a method of a User Equipment, UE, in a 3rd Generation Partnership Project, 3GPP, compliant mobile communications network supporting dual connectivity, and a corresponding UE. The method comprises detecting a signalled reconfiguration procedure of a Data Radio Bearer, DRB, having or changing to a DRB type in which downlink, DL, data is received from only serving cells of a Secondary Cell Group, SCG, connected to a Secondary eNB, SeNB, via an SCG DRB, or in which DL data is received from a SCG and also from serving cells of a Master Cell Group, MCG, connected to a Master eNB, MeNB, via a split DRB. If a DRB reconfiguration procedure type including one or more of: a handover; an SCG change; and DRB type change; is detected, the method further comprises: deciding one or more required layer 2 DRB-related actions resulting from the DRB reconfiguration based on: the initial DRB configuration; the final DRB configuration; and relevant DRB reconfiguration procedure types; and performing said decided layer 2 DRB-related actions.

    Abstract: A method, by a terminal, of performing a random access in a wireless communication system is provided. The method includes identifying a random access occasion configured for an active uplink (UL) bandwidth part (BWP) of a serving cell and when the serving cell is a special cell (SpCell) and an identity (ID) of an active downlink (DL) BWP does not correspond to an ID of the active UL BWP, switching the active DL BWP to a DL BWP with ID corresponding to the ID of the active UL BWP, based on BWP configuration information for the serving cell, and performing a random access on the switched DL BWP.
