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： In a communication system having a plurality of user equipment (UE) devices that are operating in a contention based mode for device-to-device (D2D) communication, each UE device transmits a preferred transmission indicator when a condition for preferred transmission is met at the UE device. If a UE device receives a preferred transmission indicator, the UE device delays transmission of a D2D scheduling assignment (SA) to contend for communication resources for D2D communication. The length of the delay can be based on a number of preferred transmission indicators that are received. The preferred transmission indicator is based on a buffer size in one example.

摘要： A transmitting user equipment (UE) device selects between a cellular communication link and a device-to-device (D2D) communication link for transmission for data from the transmitting UE device to a receiving UE device. Based on cellular channel characteristic information and D2D channel characteristic information, the UE device selects between the cellular communication link and the D2D communication link. The cellular channel characteristic information is indicative of at least a portion of a cellular communication link through a base station (eNB) and the D2D channel characteristic information is indicative of the D2D communication link between the transmitting UE device and the receiving UE device.

摘要： An apparatus, system, and method dynamically adjust an antenna network frequency response in accordance with an operation mode of a half duplex call. One of a plurality of antenna network configurations is selected based at least partly on the half duplex operation mode which comprises a talk mode and a listen mode. When the portable communication device is in a listen mode, the antenna network is tuned to a reception configuration which results in a reception efficiency that is greater for at least a portion of a reception frequency band than the reception efficiency resulting from at least one other antenna network configuration. The antenna network is maintained in a default configuration unless antenna adjustment conditions are met. In some situations, the antenna network is set to a transmission configuration to improve transmission efficiency relative to the default configuration.

摘要： An apparatus, system, and method manage a transmission antenna system by measuring an antenna performance indicator of an alternate antenna configuration during a reduced data rate transmission. After an antenna performance indicator is measured in a current (first) antenna system configuration, the antenna system is configured to an alternate (second) configuration during a reduced data rate transmission and the antenna performance indicator of the alternate (second) configuration is measured. The antenna performance indicators for both configurations are evaluated to determine the optimum antenna system configuration for transmission. If the alternate (second) configuration will result in decreased performance, the antenna system is changed back to the first antenna system configuration. Otherwise, the alternate (second) configuration is defined as the current configuration and the first antenna configuration is evaluated during reduced rate transmissions.

摘要： A detecting base station transmits user zone information to wireless communication device when the presence of a wireless communication device is detected. A detecting base station receives a detection signal, such as an uplink signal, transmitted from the wireless communication device to determine the presence of the wireless communication device. The detecting base station notifies the core network the detection by transmitting a device proximity message and, after receiving authorization from the network, transmits the user zone information within the broadcast channel used by the originating base station communicating to the wireless communication device.

摘要： A base station is configured to reduce interference with other base stations and/or devices in a multi-cell wireless network. The base station includes a wireless interface, detector and controller. To reduce interference, the wireless interface may provide services to a first wireless communication device (WCD) using a pilot signal emitted from the base station at a reduced power level. In the reduced pilot signal mode, when the detector detects a second WCD within the base station's service area, the controller increases the pilot signal's power level above the reduced power level in order to establish communications with the second WCD. Upon successfully connecting to the first and second WCDs, the base station may again reduce the pilot signal's power level to reduce interference with other base stations or wireless devices.
