摘要： A broadcast-centric cellular communication system improves broadcast channel performance by exploiting the benefits of macro-diversity in a cellular communication system having a plurality of base stations that transmit signals within a plurality of associated cells. The system constructs an identical paging signal at the plurality of base stations, and controls the base stations to simultaneously transmit the identical paging signal. A mobile station camps on a paging channel that is common to the plurality of base stations, and listens to paging messages being simultaneously broadcast by the plurality of base stations. The mobile station selects a base station having a suitable signal quality, and transmits to the selected base station, a response to a paging message addressed to the mobile station.

摘要： In a wireless network, plural downlink signals from plural base stations (210-1, 210-2, 210-3) are transmitted to a terminal (240). The plural downlink signals all carry the same information to the terminal (240). The terminal (240) provides feedback on the downlink channels. The feedback provides information on the taps of the channels. The amount of information fed back is constrained. Based on the feedback, transmission parameters of the downlink signals are adjusted. The process of transmitting, providing feedback, and adjusting the parameters continue so that the energy of the downlink signal is enhanced at the terminal location and suppressed elsewhere. Beam forming can be used to further suppress the energy signature at locations other than the terminal location.
摘要翻译：在无线网络中，来自多个基站（210-1,210-2,210-3-3）的多个下行链路信号被发送到终端（240）。多个下行链路信号都携带相同的信息到终端（240）。终端（240）提供对下行链路信道的反馈。反馈提供有关通道的抽头的信息。反馈的信息量受到限制。基于反馈，调整下行链路信号的传输参数。发送，提供反馈和调整参数的过程继续进行，使得下行链路信号的能量在终端位置得到增强，并在其他地方被抑制。波束形成可用于进一步抑制终端位置之外的位置处的能量特征。

摘要： The present invention relates to a broadcast-centric cellular communication system that improves broadcast channel performance by exploiting the benefits of macro-diversity in a cellular communication system having a plurality of base stations that transmit signals within a plurality of associated cells. System-specific control information common to all cells is synchronously and simultaneously broadcast from multiple base stations using a broadcast channel that is identical across the entire system. Cell-specific control information is transmitted individually from each base station. Mobile stations use the broadcast information for initial synchronization to the system, and to obtain most relevant system information. After system synchronization, the mobile stations identify the connected cell through a physical layer characteristic, and perform initial access to the system. The invention furthermore relates to a mobile station for operating in such communication system and a method in said mobile station.

摘要： A method and arrangement for improving channel decoding performance in a radio receiver. Data bits from previously decoded messages are analyzed to provide a priori information to a channel decoder (27), which is decoding a currently received message of the same type. The invention may analyze both the header and data fields of the previously decoded message frames to detect fields that are unchanging or rarely changing from one frame to the next. Probabilistic knowledge (a) of the bits in these unchanging or rarely changing fields is then used to improve the decoding performance for the current message (39). If a message cannot be successfully decoded, soft values of the bits are stored (46) and then soft-combined (48) with selected bits in the next message received prior to decoding. The invention is applicable to any type of message that has data components that are repeated with varying degrees of probability in successive transmissions.
摘要翻译：一种用于提高无线电接收机中的信道解码性能的方法和装置。分析来自先前解码的消息的数据比特，以将先验信息提供给频道解码器（27），该解码器解码当前接收到的相同类型的消息。本发明可以分析先前解码的消息帧的报头和数据字段，以检测不一致或很少从一帧改变到下一帧的场。然后使用这些不变或很少变化的字段中的比特的概率知识（a）来提高当前消息的解码性能（39）。如果消息无法被成功解码，则在解码之前，将比特的软值存储（46），然后与接收到的下一个消息中的所选位进行软组合（48）。本发明可应用于具有在连续传输中以不同程度的概率重复的数据分量的任何类型的消息。
