    Abstract: The present disclosure relates to providing a method of improving data rates in a heterogeneous network which is composed of macro cells and pico cells. User equipment is connected to the network via a macro base station serving a macro cell or a low power node serving a pico cell. A signal strength indicator is received from one or more UEs located in a macro cell and adjacent one or more pico cell. The location of a UE within a region of a macro cell or a pico cell is identified according to the signal strength indicator. Then, a weak coverage area of macro cell is identified according to the signal strength indicator and a beam forming antenna of a macro base station serving the macro cell where the UE is located, is directed to steer the antenna beam to an area of the cell requiring an improved signal strength indicator.

    Abstract: Methods and apparatus are provided for sensing a paper low condition for fan-folded tickets in a ticket printer. An aperture is provided in a bottom portion of a paper tray which supports a stack of fan-folded tickets. The aperture may be positioned underneath an end of the ticket stack. A reflective sensor is positioned underneath the aperture. Light from the reflective sensor is reflected off a bottom ticket of the ticket stack and back to the sensor when the bottom ticket covers the aperture, indicating the presence of the tickets in the paper tray. A paper low condition may be sensed when enough tickets are printed such that the end of the ticket stack is lifted off the bottom portion of the paper tray and away from the aperture such that light is not reflected back to the sensor.

    Abstract: Presented is an apparatus and methods for determining if a determined systematic imbalance difference between a serving base station and one or more candidate base stations exceeds a threshold value and, if so, then using uplink information as part of a handover mechanism. The selective usage of uplink information in the handover mechanism can improve handover performance without unduly adding to complexity and signaling overhead.

    Abstract: The base stations in a coordinating set, i.e., CoMP set, implement distributed V-MIMO processing to decode uplink signals transmitted from multiple user terminals over the same time and frequency resources. Each base station uses the extrinsic information received from its coordinating base stations to facilitate demodulation and decoding. In the event that one of the base stations successfully decodes an uplink signal, it may provide the decoded data to the other coordinating base stations in the coordinating set. In this case, the coordinating base stations do not need to decode the uplink signal. Even if the uplink signal is not successfully decoded, the demodulated data received from the coordinating base station increases the likelihood of successfully decoding uplink signal in the next iteration of a HARQ process.

    Abstract translation: 协调集合中的基站,即CoMP集合,实现分布式V-MIMO处理,以在相同的时间和频率资源上解码从多个用户终端发送的上行链路信号。 每个基站使用从其协调基站接收的外在信息来促进解调和解码。 在基站中的一个成功解码上行链路信号的情况下,它可以将解码的数据提供给协调集合中的其他协调基站。 在这种情况下,协调基站不需要对上行链路信号进行解码。 即使上行链路信号没有成功解码,从协调基站接收到的解调数据增加了下一次HARQ过程中成功解码上行链路信号的可能性。
