摘要： A serving base station allocates communication resources to be used by an aerial vehicle user equipment device (AV-UE) for uplink data transmissions. A neighboring base station is informed, via an air interface, of the communication resources that were allocated to the AV-UE. In some examples, the AV-UE retransmits scheduling assignment information, received from the serving base station, to the neighboring base station. In still other examples, the AV-UE transmits a sounding reference signal (SRS) to the neighboring base station. The neighboring base station can decode the retransmitted scheduling assignment information and/or the SRS to obtain information regarding the communication resources that have been allocated to the AV-UE for uplink data transmissions. The neighboring base station mitigates interference from the uplink data transmissions sent by the AV-UE.

摘要： 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.

摘要： The methods and systems discussed herein describe a first wireless communication device forwarding a first reservation signal, which identifies one or more time-slots that have been reserved by a second wireless communication device, to avoid “merging collisions.” In some examples, the first wireless communication device also receives a second reservation signal from a third wireless communication device, which identifies at least one time-slot that is the same as a time-slot that was identified in the first reservation signal. The first wireless communication device transmits a forwarded reservation signal that identifies the time-slots reserved by whichever of the second wireless communication device and the third wireless communication device has higher priority data to transmit. In other examples, the first wireless communication device transmits the forwarded reservation signal if a received power value of the first reservation signal is within a pre-defined received power range.

摘要： The methods, devices, and systems discussed herein describe a wireless communication device transmitting a discovery channel message, at least a portion of which, is embedded in the control channel of a groupcast transmission. In some examples, the discovery channel message is transmitted using a pre-defined, fixed transmit power and modulation and coding scheme (MCS), which facilitates the receiving wireless communication devices' ability to decode the control channel, including the embedded discovery channel message. If a receiving wireless communication device can decode the discovery channel message above a configured threshold (e.g., a received power threshold and/or a signal-to-noise ratio (SNR)) but is unable to decode the data portion of the groupcast transmission, which was intended for the receiving wireless communication device, then the receiving wireless communication device will transmit a negative-acknowledgement (NACK) to the wireless communication device that transmitted the groupcast transmission.

摘要： A base station broadcasts information to machine type communication (MTC) devices in the coverage area of the base station using multiple transmissions with layered modulation. Each transmission includes a different sequence of bits representing the information. A MTC device receiving the signals for the transmissions at a sufficiently high quality can recover the information by using a high modulation order on one of the transmissions. A MTC device receiving the signals of the transmissions at less than the sufficient quality can receive the information by applying a lower modulation order to multiple transmissions.

摘要： Systems and methods for transparent handovers of mobile relays on high-speed vehicles. In an embodiment, a base station of a wireless communications network transmits identification data to a mobile relay on a high-speed vehicle. The identification data identifies base stations which are configured for transparent handovers. The network also receives data indicative of a scheduled path of the high-speed vehicle, which it uses to select a target base station for communication with the mobile relay. Once the target base station has been selected, the network begins servicing the mobile relay from the second base station, without requiring any measurement values from the mobile relay and without handover signaling.

摘要： In a communication system that includes at least a first base station (206) having a first geographical service area (12) and second base station (210) having a second geographical service area (16) that overlaps at least partially with the first geographical service area (12), a relaying mobile wireless communication device (202) receiving service from the second base station (210) receives and forwards scheduling information (204) to the second base station (210), where the scheduling information (204) is transmitted by the first base station (206) and identifies communication resources that will be used for wireless communication with the first base station. Based at least on the scheduling information, the second base station (210) schedules communication resources to mobile wireless communication devices (202, 212) receiving service from the second base station (210) such that interference is reduced, minimized, or eliminated.

摘要： A system and method are described for determining when to exit an existing wireless communication coverage network. The method samples the device geographical position, determines a threshold boundary line, measures the position of each sample point with respect to the threshold boundary line, and, beginning at a predetermined initial value, maintains a running sum in response to measuring position. The existing coverage network is exited when the running sum is greater than or equal to a predetermined terminal value.

摘要： The methods, devices, and systems discussed herein describe a wireless communication device broadcasting a periodic discovery channel message that includes an identifier associated with the wireless communication device that indicates its presence to neighboring wireless communication devices. If the neighboring wireless communication devices receive the periodic discovery channel message transmission above a pre-defined received power threshold and successfully decode the periodic discovery channel message, then the transmitting wireless communication device is added to the neighboring wireless communication devices neighboring device list. After receiving the periodic discovery channel messages from all of the neighboring wireless communication devices, a wireless communication device is able to identify all of its immediate neighboring devices and form its neighboring device list. Based on detecting periodic discovery channel message transmissions, a wireless communication device periodically updates its neighboring device list with new additions or removals of neighboring wireless communication devices.
