摘要： A system and method are presented for determining when to exit an existing wireless communications 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 method uses the threshold boundary line to partition a coverage area for the existing coverage network into first and second zones. Then, the method decrements the running sum for sample point positions in the first zone and increments the running sum sample point positions in the second zone. The method exits the existing coverage network when the running sum is greater than or equal to a predetermined terminal value and then resets the running sum to the predetermined initial value.

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： A relay node receives a data block containing multiplexed data streams intended for multiple user equipment (UE) devices being served by the relay node. The relay node extracts the data streams from the data block and allocates them each to a separate narrowband channel that is associated with a particular UE device. The relay node repeatedly transmits the narrowband channels to the UE devices in a broadcast transmission that is transmitted for a predetermined number of repetitions. Each UE device decodes their own respective narrowband channel to obtain the data stream intended for the UE device associated with a particular narrowband channel. A feedback mechanism is utilized by the relay node to determine whether to retransmit a data packet or a new data packet in subsequent broadcast transmissions.

摘要： 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.

摘要： A mesh network communication system includes a plurality of access points connected to a wireless local area network (WLAN) controller where at least one access point is a detection access point (DAP) that receives reverse link (RL) wireless wide area network (WWAN) signals transmitted from a multi-mode wireless communication device. Based on an intercepted RL WWAN signal, the DAP forwards reverse link (RL) information to the WLAN controller, which then generates and sends, to the WWAN communication system, a device to access point association list (device-AP association list) comprising one or more device identifiers associated with one or more target access point identifier. The device identifier uniquely identifies a multi-mode wireless communication device within a maximum proximity of a target access point identified by the target access point identifier. The WWAN system applies the device-AP association list to efficiently manage handoffs to access points in the mesh network.

摘要： An access node receives a device beacon transmitted from a wireless communication device in accordance with a system timing of a wireless wide area network (WWAN). When transmitted within a WWAN uplink channel, the device beacon is mapped to designated beacon channels within the time-frequency space of the uplink WWAN channel assignment. In response to the reception of the device beacon, communications between the wireless communication device and the access node are established. In one example, the access node is a femtocell base station. In another example, the access node is a wireless local area network (WLAN) access point.
