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.

Adjusting polarization states for wireless transmission

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.

Broadcasting public warning messages over N3GPP access node of a non-3GPP network

A method for controlling access to a radio channel in a single frequency network in which multiple base stations transmit the same data simultaneously to a user equipment, UE device, includes a first plurality of base stations transmitting a set of random access parameters of the single frequency network. The method also includes a second plurality of base stations receiving a random access preamble transmitted by the UE device. The second plurality of base stations the same or a subset of the first. The method also includes transmitting responses to the random access preamble from a third plurality of bases stations. The third plurality of base stations the same as or a subset of the second. The method also includes a fourth plurality of base stations receiving a scheduled transmission in response to the responses. The fourth plurality of base stations the same as or a subset of the third.

Single frequency network random access

The present invention provides a method of selecting an optimal communication routing between a UE and a core network wherein a plurality of differing communication paths are establishable between the UE and the network. Duplicate packets are transmitted over two communication paths and a latency difference determined between the two paths. This latency difference is used to select a communication path for subsequent communication.

Differential latency measurement

A method of providing feedback from a plurality of base stations of a single frequency network to a user equipment device to indicate if a data transmission has been received successfully, wherein a positive acknowledgement of successful receipt is transmitted using a first feedback resource and a negative acknowledgement of unsuccessful receipt is transmitted using a second feedback resource, the first and second feedback resources being mutually orthogonal.

ACK/NACK messaging in a single frequency network

The present invention provides a method of communicating vehicle positioning information, wherein signals are transmitted from at least one vehicle mounted antenna for indicating a position of the vehicle to another entity, the signals including information concerning at least one of an identity of the at least one antenna and information providing a displacement between the at least one antenna and a boundary of the vehicle.
