Abstract: Notifying served user equipments (UEs) of the presence or absence of cell-specific reference signal (CRS) symbols transmitted by neighboring base stations in the physical downlink shared channel (PDSCH) region of a subframe can be achieved through various of signaling techniques. The served UE may be notified by communicating a one or multi-bit indicator in a physical layer signaling channel of the serving cell, such as the physical downlink control channel (PDCCH) of the subframe. Alternatively, the served UE may be notified through higher layer signaling.

Abstract: A method and system for including a base station that configures a first user equipment (UE) that is in a radio resource control connected state with the base station. The UE is configured to be a synchronization source and transmit a first device-to-device synchronization signal (D2DSS) by using a synchronization resource that comprises a time resource, a frequency resource or a time and frequency resource. The base station instructs the first UE to transmit the first D2DSS using the synchronization resource. The base station signals the UE to configure the UE separately from the signal to transmit the D2DSS, and both of the signals are performed with radio resource control signaling from the base station to the UE.

Abstract: A method for allocating network resources to user equipments (UEs) includes configuring a first group of component carriers with resource allocations indicated by a joint downlink control information (DCI) message, configuring a second group of component carriers with resource allocations for each component carrier indicated by a dedicated DCI message, generating the joint DCI message indicating first resource allocations for a first subset of the first group of component carriers, generating a plurality of dedicated DCI messages, wherein each dedicated DCI message indicates a second resource allocation for a component carrier in a second subset of the second group of component carriers, mapping each one of the joint DCI message and the plurality of dedicated DCI messages to a control channel, and sending the control channels to the UE.

Abstract: When at least one of device-to-device UEs in connections of a group of D2D UEs is outside of the coverage area of mobile network of an access point, an information exchange mechanism established directly between the D2D UEs without involving a third party, is provided. A Sidelink Control Information (SCI) message type comprises one or more format flags indicating the respective resource allocation format, obtaining a first SCI message, adjusting a size of the first SCI message based on the determined size, and transmitting the adjusted first SCI message by a first UE in a Physical Sidelink Control Channel (PSCCH) to one or more second UEs for establishing the D2D communication link.

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: An embodiment of a system for operating a communications controller for a group of user equipments engaged in a DMC link in a wireless communications system is provided. The communications controller is configured to allocate a set of subframes in one periodic group of subframes to the group of UEs for the DMC link, signal the set of allocated subframes to the group of UEs, and transmit parameters related to a group of HARQ processes of the DMC link. In an embodiment, the communication controller uses HARQ processes for cellular UE transmission that are determined independently from HARQ processes of the group of HARQ processes for the DMC link, and the parameters are configured to enable the group of UEs to manage the group of HARQ processes for the DMC link.
