The present invention provides for a method and related system and communication terminal devices, for assigning a radio resource allocation mode to a mobile radio communications device for device-to-device communication within a wireless communication network environment, the method including the step of identifying at the mobile radio communications device an initial radio resource allocation mode and further including the step of signalling from the network to the mobile radio communications device configuration data relating to an authorized radio resource allocation mode to be employed for the device-to-device communication and defining at least one operation requirement of the mobile radio communications device when employing the said authorized mode.

Device-to-device radio resource management

The present invention provides for a method of configuring a physical channel, such as a physical control channel, for device-to-device communication between mobile terminal devices within a cellular communications network environment and comprising a step of locating a device-to-device control channel within a cellular uplink signaling spectrum, and applying a frequency offset parameter to determine separation of the device-to-device control channel from a cellular uplink control channel, and to related terminal devices and computer program products.

Channel configuration in device-to-device communications

The present invention provides for a method of configuring a physical channel, such as a physical control channel, for device-to-device communication between mobile terminal devices within a cellular communications network environment and comprising a step of locating a device-to-device control channel within a cellular uplink signalling spectrum, and applying a frequency offset parameter to determine separation of the device-to-device control channel from a cellular uplink control channel, and to related terminal devices and computer program products.

A mobile device () configured to provide relay capabilities in a communications system () by communicating network-level mobile device relaying capabilities and radio-level mobile device relaying capabilities from the mobile device () to a communications node () of the communications system () so that the mobile device () can relay communications between the communications node () and another mobile device (). User subscription information related to relaying is also disclosed.

Mobile communications device and system

The invention relates to a method for relaying a communication in a network, wherein a user equipment (UER) relays a communication between a network node entity (eNB) and a target entity (UET), the method including the steps, generating a logical channel at least between the user equipment relay (UER) and the target entity (UET), and assigning at least one identifier (LC_ID_R) to said logical channel, and upon reception from the network node entity (eNB), at the user equipment relay (UER), of data received with said identifier (LC_ID_R), the user equipment relay (UER) forwards the received data to the target entity (UET).

Optimized user equipment supporting relay communication, and related method

The invention relates to a method for relaying a communication in a network, wherein a user equipment (UER) relays a communication between a network node entity (eNB) and a target entity (UET), the method including the steps, generating a logical channel at least between the user equipment relay (UER) and the target entity (UET), and assigning at least one identifier (LC_ID_R) to the logical channel, and upon reception from the network node entity (eNB), at the user equipment relay (UER), of data received with the identifier (LC_ID_R), the user equipment relay (UER) forwards the received data to the target entity (UET).

Optimized user equipment replaying

A communications apparatus capable of detecting a signal transmitted by another apparatus in a first band of spectrum is described. The apparatus identifies at least one second band of spectrum, different from the first band of spectrum, in which no signal is detected and then determines a noise characteristic for the at least one second band of spectrum. The determined noise characteristic may then be used by an energy detector operating in the first band of spectrum to ensure reliable detection of signals transmitted by the other apparatus.
