The present invention provides a mobile communication system sub-network comprising a macrocell base station, and a plurality of small cell base stations, the plurality of small cell base stations being in wireless communication with the macrocell base station, wherein each small cell base station is either in direct connection with the macrocell base station or is in connection with the macrocell base station via one or more other small cell base stations, wherein the macrocell base station is arranged to configure a UE device having a RRC connection to the macrocell base station with candidate small cell base station information for enabling the UE device to switch autonomously between small cell base stations, and wherein the macrocell base station is arranged to configure the small cell base stations with small cell base station configuration information.

Integrated access and backhaul mobility

The present invention provides a mechanism for a receiver to determine a quality of orthogonality of received polarized signals by monitoring polarized reference signals RSwhich either change polarization with time or are aligned with polarized data signals. Depending on the quality, multiplexing may change between polarization division multiplexing and spatial division multiplexing.

The present invention provides a method of operating a user equipment, UE device in communication with a non-terrestrial communication system comprising a plurality of transmission points, the method comprising in the UE device triggering a transmission of a measurement report dependent on a measurement by the UE device of a received signal parameter of a signal received from a transmission point of the system and a comparison of the measured parameter with a threshold, the threshold varying according to a predetermined function dependent on an expected position of the UE device with respect to the transmission point.

Predictive measurement for non-terrestrial communication

The present invention provides a method of determining a transmission power for device to device, D2D, transmissions between a first user equipment device and a second user equipment device using transmission resources being used for transmissions to a cellular network entity by a third user equipment device, the method comprising determining a measure of a path loss between the cellular network entity and the first user equipment device, and using the measure of the path loss to determine a maximum transmission power such that the D2D transmissions are received at the cellular network entity with a signal level around or below a noise level.

Reuse of transmission resources for device to device communication

The present invention provides a method of performing by a UE device a random access attempt in a communication system comprising at least one non-terrestrial transmission station, the method comprising receiving reference signals transmitted by the non-terrestrial transmission station; determining from the received reference signals a trip time between the UE device and the non-terrestrial transmission station; and using the trip time to control the random access attempt.

Random access in a satellite communication system

The invention provides a method of transferring resource control unit operational control functionality within a single frequency network, in which multiple transmission points transmit identical downlink data packets in a synchronized manner, from a first node to a second node, the method comprising receiving at a resource control unit a set of resource control information from at least one candidate node; determining using the resource control information a suitability of the at least one candidate node to be the second node; and initiating transfer of the resource control unit operational control functionality from the first node to the second node.

SFN inter node messaging

A method of reducing interference in a mobile communication system is provided to reduce interference caused by a first user equipment, UE, device operating in a cell at a significantly higher altitude than other UE devices in the cell so as to cause interference. The method detects that the first UE device is operating at an altitude considered by the mobile communication system to be an extraordinary altitude and reduces interference caused by the first UE device operating at the extraordinary altitude by controlling the operation of the first UE device.

Reducing interference from devices at extraordinary altitudes

The present invention provides a method of transmitting data to a receiving entity, the method comprising establishing a plurality of transmission channels to the receiving entity, the transmission channels being established using more than one radio access technology; for each transmission channel determining a buffer status of a data buffer containing data to be transmitted using that transmission channel; and determining if transmission capacity is available in a packet data unit of a first radio access technology and if such transmission capacity is available determining whether data may be taken from a data buffer of a transmission channel of a second radio access technology and transmitted to the receiving entity in the packet data unit.

Coordination of logical channel priorities

The present invention provides a method of establishing a wireless communication link between two infrastructure nodes in a wireless communication system, the method comprising at a user equipment, UE, device receiving a link establishment request message transmitted by a first node; obtaining information relating to a position of the first node; and transmitting a message to a second node informing the second node of the position of the first node to assist in establishing the link between the first and second nodes.

Communication system link establishment

A method of enabling a provision of public warning system, PWS, messages to a user equipment, UE, device via a non-3GPP radio network including establishing an internet protocol security, IPSec, tunnel connection from the UE device to a non-3GPP interworking function, N3IWF, via a non-3GPP, N3GPP, radio access technology, requesting from a first core network, CN, entity a provision of public warning system, PWS, messages; and providing the first CN entity with information about a location of the UE device.
