Abstract: A device is configured to perform a method of device-to-device (D2D) communication in a wireless communication network in accordance with a Long Term Evolution (LTE) standard. The method includes entering an RRC-Idle state or an RRC-Connected state. The method also includes transmitting, in the RRC-Idle state or RRC-Connected state, a D2D discovery signal for receipt by at least one second device in the network. The method further includes receiving, in the RRC-Idle state or RRC-Connected state, at least one D2D discovery signal from the at least one second device in the network.

Abstract: Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

Abstract: A system and method of scheduling transmissions. A wireless device such as an eNodeB (eNB) may schedule a transmission of a wideband (WB) signal on a micro-frame selected from a plurality of WB micro-frames of a WB carrier. A narrowband (NB) subframe may span a portion of the selected WB micro-frame in the frequency-domain, and the selected WB micro-frame may overlap at least a portion of the NB subframe in the time-domain. The WB signal and an NB signal may be transmitted over the WB micro-frame and the NB subframe in accordance with a first numerology and a second numerology, respectively. A WB subframe may be divided into a plurality of micro-frames. The transmission direction of the WB micro-frame may be scheduled according to a transmission rule based on the contents of a payload in the NB subframe.

Abstract: In certain embodiments, a method includes, by a first mobile device, obtaining a data packet and determining, from a first set of resources, control resources for transmitting scheduling information associated with the data packet. The control resources include a physical sidelink control channel (PSCCH). The method includes determining, by the first mobile device from a second set of resources, acknowledgement (ACK)/negative acknowledgement (NACK) resources associated with the data packet and related to the control resources. The scheduling information includes transmission information for transmitting the data packet and an indication of the ACK/NACK resources. The method includes transmitting, by the first mobile device to a second mobile device, the scheduling information on the control resources and the data packet on a set of resources indicated by the transmission information and listening, by the first mobile device, for an ACK/NACK transmitted by the second mobile device on the ACK/NACK resources.

Abstract: A method includes determining a first subframe on which to transmit a first downlink control information (DCI) message and determining a second subframe on which to transmit a first information. The method also includes determining a delay between the first subframe and the second subframe and transmitting, by a communications controller to a user equipment (UE), the second subframe in accordance with the delay.

Abstract: A device and method for transmission and reception of control and data channels with a group reference signal (GRS). A GRS may include a first common reference signal associated with a first group of users and a second common reference signal associated with a second group of users. Some users or channels can be grouped to use one set of common reference signals and other users or channels can be grouped to use another set of common reference signals.

Abstract: 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.
