摘要： A system and method for paging wireless mobile devices selectively varies the effective modulation order of a paging channel to achieve improved coverage in a wireless wide area network (WWAN) cell. In one embodiment, the paging channel modulation order is selected based on a measured signal strength and/or common channel error rate. The selected modulation order is directly related to the quality of the channel environment. In another embodiment, a page message is segregated into base and extended components that are layer modulated. With layered modulation, wireless mobile devices in good coverage regions can successfully demodulate both the base and extended components to recover the entire page message. Wireless mobile devices in poor coverage regions can successfully demodulate the base component of the page message, and then request that the extended component of the page message be re-broadcast as a base component to thereby recover the entire page message.

摘要： To improve WWAN coverage, an access node broadcasts overhead messages on a first channel covering a first channel environment and a second channel covering a second channel environment within a coverage region. The overhead messages carry network overhead parameters for allowing wireless mobile devices to acquire and maintain traffic channels within the cellular system. The overhead message channels are configured so that a user perceives uninterrupted wireless services while moving through different channel environments in the coverage region. In one embodiment, the overhead message channels are separate physical channels configured with different broadcast parameters to provide coverage in different environments. In another embodiment, the overhead parameter information is segregated into base and extended components that are encoded and layer modulated onto separate logical channels. Using layered modulation, wireless mobile devices can receive base components in poor coverage regions. The base components include overhead parameters for acquiring a WWAN channel.
摘要翻译：为了改善WWAN覆盖，接入节点在覆盖第一信道环境的第一信道和覆盖覆盖区域内的第二信道环境的第二信道上广播开销消息。开销消息携带网络开销参数，以允许无线移动设备获取和维护蜂窝系统内的业务信道。开销消息信道被配置为使得用户在移动通过覆盖区域中的不同信道环境时感知不间断的无线服务。在一个实施例中，开销消息信道是配置有不同广播参数的分离物理信道，以在不同环境中提供覆盖。在另一个实施例中，开销参数信息被分离成基本和扩展组件，其被编码和层调制到单独的逻辑信道上。使用分层调制，无线移动设备可以在较差的覆盖区域中接收基本组件。基本组件包括用于获取WWAN通道的开销参数。

摘要： A base station routes data between a wireless communication device and a local device through a local network. When a route-local indicator is received from the wireless communication device, the base station routes data through the local network to the local device without routing the data through a cellular network. Accordingly, the physical path of the data includes the base station and the local network and does not include cellular equipment other than the base station.

摘要： An origination device (e.g., a base station) transmits a “received signal” to a signal forwarding device. The “received signal” comprises a first set of data, a first set of control information, and a second set of control information. The first and second sets of control information are both associated with the first set of data. The first set of control information contains instructions pertaining to the signal forwarding device processing the first set of data. The second set of control information contains instructions pertaining to a destination device (e.g. a user equipment (UE) device) processing the first set of data. The signal forwarding device transmits a “forwarded signal” to the destination device. The “forwarded signal” contains forwarded data, based on the first set of data, and forwarded control information, based on the second set of control information.

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： 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 device-specific synchronization signal (DS-SS) is transmitted by a base station within a data channel transmission prior to a page timing window (PTW) of designated for at least one mobile device. The DS-SS includes a plurality of sequence instances where each sequence instance is based on a single root sequence. Prior to entering a sleep state, the mobile device receives transmission information indicative of the DS-SS transmission including at least one of a timing and format of the DS-SS transmission. After a sleep state, a mobile device acquires the DS-SS.

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.

摘要： A receiving user equipment (UE) device sends a location unavailable notification to a transmitting UE device indicating that location information is unavailable. The receiving UE device is one of a group of UE devices receiving a groupcast data transmission from the transmitting UE device where the groupcast data transmission comprises a distance-based hybrid automatic repeat request (HARQ) feedback configuration. The receiving UE determines that location information is unavailable and sends the location unavailable notification. The location unavailable notification may be a broadcast message or message send over unicast communication link.

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.
