摘要： A device is configured to perform a method of wireless communication in a wireless communication network. The method includes receiving, from a communications controller, a device-to-device (D2D) subframe configuration to communicate with one or more second wireless devices, the subframe configuration indicating one or more subframes in which to transmit a D2D signal or receive one or more D2D signals. The method also includes receiving, from the communications controller, scheduling information to transmit a first signal to the communications controller on a subframe indicated by the D2D subframe configuration. The method further includes prioritizing the transmission of the first signal over a transmission of the D2D signal or a reception of the one or more D2D signals, and transmitting the first signal.

摘要： Embodiments are provide for communicating data or other non-control information messages within a downlink control channel directly, rather than in a data channel or broadcast channel. Thereby, radio resource utilization can be substantially improved in the cellular system, such as in the case of transmitting smaller data packets. In an embodiment, a transmitter arranges a set of time-frequency radio resources, associated with a downlink control channel, for transmitting information other than control information sent on the downlink control channel. The transmitter then sends, on the set of time-frequency radio resources, a data information message comprising the information other than the control information. The information other than the control information comprises one of user-specific data information and broadcast data information. A receiver then receives on the downlink control channel, control information and the data information message.

摘要： A method for performing open discovery in a communications system includes determining, by a device-to-device (D2D ) device, resource allocation information for a discovery cycle including discovery resources allocated for transmission of discovery signals by D2D devices. The method also includes selecting, by the D2D device, a first discovery resource of the discovery cycle in accordance with the resource allocation information, and transmitting, by the D2D device, a discovery signal in the selected first discovery resource.

摘要： A system and method for transmitting control information are provided. A method for communications controller operations includes combining control data for each relay node of at least one relay node into a control channel data stream, mapping a plurality of transmission resources for the control channel data stream into a plurality of physical resource blocks using a distributed virtual resource mapping rule, and transmitting the plurality of physical resource blocks to the set of at least one relay node. The plurality of transmission resources are mapped to physical resource blocks that are non-contiguous in a frequency domain.

摘要： Embodiments are provided to support device-to-device (D2D) communications in a time-division duplexing (TDD) communications system, and ensure that D2D discovery signals are transmitted by user devices on an uplink subframe when there is a TDD frame configuration change. In an embodiment, a user device receives form the network a TDD frame configuration selected from a set of available TDD frame configurations according to the TDD configuration. The device further receives a D2D discovery configuration for a discovery time interval. The user device then allocates a transmission resource a D2D discovery signal within the discovery time interval according to the D2D discovery configuration. The user device is also configured to receive from another device a second D2D discovery signal during the discovery time interval in accordance with the TDD configuration and the D2D discovery configuration.
