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： An exemplary method for selecting one of a plurality of systems on a multi-mode device capable of communicating on a first air interface technology and a second air interface technology is disclosed. Initially, a carrier input associated with one of the first and second air interface technologies is received. The carrier input typically defines at least one system selection event. Next, a first network acquisition attempt of the other one of the first and second air interface technologies is triggered responsive to the system selection event. The results of the first network acquisition attempt are determined and stored, and subsequently used for subsequent system selection determinations between the first and second air interface technologies.

摘要： In response to detecting a call attempt for a priority call on the originating wireless network by an initiating access terminal, at least one active call having a priority level less than the priority call is transferred to an alternate technology wireless network. If a call attempt is placed when a transfer threshold has been exceeded, candidate transferring terminals are identified based on multi-mode capabilities and network conditions. One or more of the candidate transferring terminals engaged in calls that have a priority level less than the priority call are transferred from the originating wireless network to the alternate technology wireless network when the transfer threshold is exceeded.

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： 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： A common group cell identifier is transmitted by adjacent base stations. Handover processing is minimized for mobile relays traveling along a predetermined path that traverses the adjacent base stations. A first base station along the path transmits a group cell identifier and a first single cell identifier within a first service area. An adjacent base station transmits the group cell identifier and a second single cell identifier within a second service area that at least partially overlaps the first service area. The mobile relay monitors the group cell identifier in certain situations and only performs a handover when the group cell identifier changes. As a result, no handovers are initiated as the mobile relay travels down the path since the group cell identifier transmitted by the base stations along the path are the same.

摘要翻译： 公共组小区标识符由相邻基站发送。 对于沿着穿过相邻基站的预定路径行进的移动中继站，切换处理被最小化。 沿着路径的第一基站在第一服务区域内发送组小区标识符和第一单个小区标识符。 相邻基站在与第一服务区域至少部分重叠的第二服务区域内发送组小区标识符和第二单个小区标识符。 移动中继在某些情况下监视组信元标识符，并且仅当组信元标识符改变时执行切换。 结果是，由于基站沿着路径发送的组小区标识符相同，因此随着移动中继站沿着路径的向下移动，不会切换切换。
