    Abstract: In a communication system that includes at least a first base station having a first geographical service area and second base station having a second geographical service area that overlaps at least partially with the first geographical service area, a relaying mobile wireless communication device receiving service from the second base station receives and forwards scheduling information to the second base station, where the scheduling information is transmitted by the first base station and identifies communication resources that will be used for wireless communication by the first base station. Based at least on the scheduling information, the second base station schedules communication resources to mobile wireless communication devices receiving service from the second base station such that interference is reduced, minimized, or eliminated.

    Abstract: An eNB transmits a preamble signal including synchronization information before transmitting data in an unlicensed band where the synchronization information is in accordance with a licensed frequency band communication standard used in a primary cell (Pcell) provided by the eNB. The preamble signal is transmitted in accordance with a timing structure used in the Pcell using the licensed frequency band. The eNB provides a secondary cell (Scell) that has a service area that at least partially overlaps with a service area of the Pcell. The preamble signal provides synchronization information to a user equipment (UE) device for the Scell.

    Abstract: A base station (eNB) determines device-to-device (D2D) transmission parameters for signal transmission over a D2D communication link between a first user equipment (UE) device and a second UE device. The eNB instructs the first UE device to transmit a reference signal that is received by the second UE device. The second UE device reports D2D channel characteristic information indicative of the received reference signal. Based on the D2D channel characteristic information, the base station determines the D2D transmission parameters and provides the parameters to the first UE device.

    Abstract: A first wireless communication device transmits a reference signal at a series of transmission times to transmit a plurality of reference signals over time. The first wireless communication device receives a communication signal from a second device. In response to determining at the first device that an acknowledgment response should be sent to the second device in response to the communication signal, the first wireless communication device applies a code to the reference signal for at least one of the transmission times of the series of transmission times. The resulting coded reference signal indicates an acknowledgment response to the second wireless communication device.

    Abstract: Macrocell communication resources are assigned for device-to-device (D2D) communication between two wireless communication user equipment (UE) devices. A scheduler in a communication system schedules (assigns) scheduled downlink communication resources for downlink transmission of signals from a base station, schedules (assigns) scheduled uplink communication resources for uplink communication from wireless communication (UE) devices to base stations, and schedules (assigns) (D2D) communication resources for (D2D) communication between wireless communication (UE) devices. The (D2D) communication resources are selected from either defined downlink communication resources or defined uplink communication resources that are defined by communication specification. The base station sends communication resource allocation (CRA) information to at least one of the wireless communication (UE) devices where the communication resource allocation information identifies the (D2D) communication resources for use by the wireless communication (UE) devices to communicate through a device-to-device (D2D) communication link.
