  • Publication number: 20200107334
    Abstract: A base station assigns a first set of device-to-device (D2D) communication resources to a first D2D group and assigns a second set of D2D communication resources to a second D2D group. The D2D communication resources of the first set are different from the D2D communication resources of the second set. The first set of D2D communication resources and the second set of D2D communication resources are subsets of reserved D2D communication resources which are a subset of defined uplink communication resources defined by a communication specification for uplink communication between the D2D UE devices and a base station where the reserved D2D communication resources not used for uplink transmission to the base station.

  • Publication number: 20200008097
    Abstract: A base station includes a controller that performs multicast service SC-PTM transmission, and a transmitter that transmits SC-PTM configuration information related to a configuration of the SC-PTM transmission via a SC-PTM control channel, which is a logical channel different from a MCCH, and transmits multicast data via a traffic channel for the SC-PTM transmission. Each of the SC-PTM control channel and the traffic channel is mapped on a DL-SCH. The transmitter transmits a SIB related to the SC-PTM control channel via a BCCH, transmits first resource allocation information for transmitting the SC-PTM configuration information via a PDCCH, where a predetermined RNTI for the SC-PTM control channel is applied to transmission of the first resource allocation information, and transmits second resource allocation information for transmitting multicast data by the SC-PTM transmission via the PDCCH.

  • Patent number: 10439791
    Abstract: In a time division duplex (TDD) communication system, an unconnected base station that is not directly connected to a core network transmits uplink backhaul signals to a connected base station when the unconnected base station is transmitting downlink signals to one or more user equipment (UE) devices and receives downlink backhaul signals from the connected base station when receiving uplink signals from one or more UE devices. After determining the transmission schedule of the connected base station, the unconnected base station selects a transmission schedule that is orthogonal to the connected base station transmission schedule. Depending on the particular implementation, the unconnected base station may be a repeater base station, a relay base station, or a self-backhauled base station.

  • Publication number: 20190281505
    Abstract: A user equipment (UE) device is scheduled to transmit an uplink data transmission to its serving base station. The uplink data transmission) includes a special subframe that has a different subframe structure than a subframe structure used by at least one other UE device being served by the serving base station. For example, the special subframe includes a blanked portion of the first symbol of the special subframe and a higher Reference Signal symbol density when compared to the subframe structure used by other UE devices. A target base station receives and decodes the uplink data transmission, utilizing the features of the special subframe to acquire and estimate the uplink channel between the UE device and the target base station. After decoding the uplink data transmission, the UE device is handed over from the serving base station to the target base station.

  • Patent number: 10412706
    Abstract: An in-coverage (InC) relay user equipment (Relay-UE) device selects a resource allocation from a communication resource pool or receives the selected resource allocation from an eNB, and then transmits the selected resource allocation to one or more out-of-coverage (OoC) UE devices. The resource allocation is for a device-to-device (D2D) communication link between the InC Relay-UE device and the OoC UE devices. After receiving the resource allocation, an OoC UE device may relay data to a base station (eNB) by way of the InC Relay-UE, using the allocated transmission resources.

  • Patent number: 10390319
    Abstract: An in-coverage (InC) user equipment (UE) device transmits a device-to-device synchronization signal (D2DSS) and device-to-device (D2D) discovery resource pool information message to an out-of-coverage (OoC) UE device. The D2DSS is based on timing information obtained directly from an eNB and based on at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The D2D discovery resource pool information message identifies a set of communication resources authorized for transmission of D2D discovery signals where the set of resources are identified in an eNB discovery resource pool message received at the InC UE device from the eNB. The OoC UE device selects communication resources from the set of communication resources to transmit a discovery signal.

  • Publication number: 20190238212
    Abstract: A signal forwarding device receives a dual-encoded first set of data that is encoded according to first and second sets of encoding parameters. The signal forwarding device decodes the dual-encoded first set of data, using decoding parameters that correspond to the second set of encoding parameters, to generate a single-encoded first set of data that is encoded according to the first set of encoding parameters. The signal forwarding device transmits the single-encoded first set of data to the destination device, which decodes the single-encoded first set of data using decoding parameters that correspond to the first set of encoding parameters. If the decoding is unsuccessful, the destination device requests retransmission. The signal forwarding device decodes a stored copy of the single encoded first set of data, using decoding parameters that correspond to the first set of encoding parameters, and retransmits the first set of data to the destination device.

  • Patent number: 10361769
    Abstract: A signal forwarding device forwards signals between a user equipment (UE) device and a base station using a partial decode and forward (PDF) signal forwarding scheme where an incoming signal is demodulated and forwarded to a destination as a forwarded signal without decoding the incoming signal. The signal forwarding device transmits, to the base station, channel information regarding the UE-SFD channel between the UE device and the signal forwarding device. A base station (BS) scheduler determines the coding rate to be used by the UE device at least partially based on the channel information. The base station transmits coding rate information indicative of the coding rate to the signal forwarding device. A signal forwarding device (SFD) scheduler schedules communication resources for use by the UE device at least partially based on the coding rate information.
