摘要:
A communication control method according to the present embodiment comprises: a step of transmitting, by a user terminal located inside a cell, detection information indicating that a D2D synchronization signal is detected, to a base station that manages the cell, when receiving the D2D synchronization signal from another user terminal; and a step of transmitting, to the user terminal, by the base station, on the basis of the detection information received from the user terminal, setting information for setting the user terminal to a D2D synchronization source.

A mobile communication system includes a base station configured to transmit system information on at least one D2D available cell in which D2D communication is available; and a user terminal that exists in a cell of the base station, and configured to receive the system information from the base station. The system information includes frequency information that indicates a frequency to which the D2D available cell belongs.

Various embodiments relate to wireless communications, and more particularly, to methods and apparatus for authorizing use of spectrum, e.g. , through the issuance of spectrum access keys, and/or preventing or discouraging the unauthorized use of licensed spectrum. Peer to peer wireless communications between authorized users of licensed spectrum may involve scrambling/descrambling of information communicated between authorized devices. In some embodiments air interface timing and/or other information received from a second device, e.g. , a beacon or GPS transmitter, is incorporated into a computation of a pseudo-random bit sequence which is also computed based on a spectrum access key communicated to authorized spectrum users. In some embodiments authorized peer to peer devices scramble communicated information based on the generated pseudo random bit sequence thereby preventing or discouraging communication with devices which are not authorized to use the spectrum and lack a spectrum access key used to generate the pseudo random bit sequence.

Systems, apparatus, user equipment (UE), evolved node B (eNB), and methods are described for machine-type communications (MTC) with narrowband deployment comprising including MTC Physical Control Format Indicator (M-PCFICH). One embodiment includes control circuitry configured to determine a super-frame structure, wherein the super-frame structure is set, at least in part, on a bandwidth of the narrowband deployment. The embodiment further comprises circuitry to determine configuration information for a UE in communication with the eNB, generate a configuration for an MTC Control Format Indicator (M-CFI) for the UE to indicate the determined configuration information, and transmit the M-CFI through a narrowband M-PCFICH within the super-frame structure.

UE 100 that supports D2D proximity service comprises: a transmitter configured to transmit a synchronization signal for D2D and a predetermined signal for D2D used for a D2D proximity service; and a controller configured to monitor a reception status of the synchronization signal and the predetermined signal. When the UE 100 is out of a network coverage, the transmitter transmits the synchronization signal, when the controller receives neither the synchronization signal nor the predetermined signal from another user terminal, the UE 100 determines that the another user terminal synchronized with the UE 100 is not present in the neighborhood.

In an embodiment, a P2P device discovers other P2P devices that belong to a P2P group. The P2P device determines a multicast address to be used for signaling related to floor arbitration of a P2P session with the P2P group. The P2P device exchanges signaling with one or more of the discovered P2P devices over a multicast signaling control channel of a P2P interface using the multicast address. The P2P device identifies a leader (e.g., the P2P device itself and/or one or more of the other P2P devices) that is responsible for performing a floor arbitration function for the P2P session. The P2P devices participates in the P2P session by exchanging media with the P2P group over a media channel of the P2P interface that is separate from the multicast signaling control channel in accordance with the floor arbitration function performed by the leader.

A method, wireless communication device, and computer readable medium, are disclosed, for wireless transmission of real-time media from a source to a sink over a wireless transmission channel. The wireless device initiates a peer-to-peer communication session between the sink and the source, and determines based on a time-allocation for the wireless transmission, an available bandwidth for the wireless transmission. The wireless device encodes the real-time media for the wireless transmission such that a time-required for transmission of the first frame-type is less than or equal to a period-of-availability for transmission defined in the time-allocation for the wireless transmission.

A serving gateway (S-GW) in a radio access network (RAN) server system for peer-to-peer (P2P) communication can include a P2P content manager. The P2P content manager can be configured for receiving P2P data content from other nodes in a P2P network, forwarding the P2P data content to other nodes in the P2P network, and transmitting the P2P data content to a mobile device associated with the S-GW in a downlink (DL) transmission. The serving gateway can be a node in the P2P network and coupled to a transmission station in the RAN. The P2P data content includes at least one P2P data packet.
