    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be 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 uplink 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 present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Described is a method for providing a Phase Tracking Reference Signal (PTRS) in a wireless communication system comprising at least a first base station and a second base station, and a mobile device. The first and second base stations cooperate to jointly support the mobile device. The method comprises identifying at least two mutually exclusive sets of frequency resources. The method further comprises mapping, by the first base station, at least a portion of PTRS information of the first base station to a first set of the frequency resources, mapping, by the first base station, a zero-power PTRS to a second set of the frequency resources, or leaving, by the first base station, the second set of frequency resources empty, and transmitting, by the first base station, a signal comprising the PTRS information of the first base station according to the frequency resource mapping. The method further comprises mapping, by the second base station, at least a portion of PTRS information of the second base station to the second set of the frequency resources, mapping, by the second base station, a zero-power PTRS to the first set of the frequency resources, or leaving, by the second base station, the first set of frequency resources empty, and transmitting, by the second base station, a signal comprising the PTRS information of the second base station according to the frequency resource mapping.
