摘要： In a cellular radio communication system, a base station or a mobile station has a TA (Time Alignment)-range-out detection function, so that when a TA-range-out state that is unable to compensate with a guard interval is detected, the transmission condition of an uplink signal at the mobile station is changed by the mobile station autonomously or by the base station and the mobile station cooperatively.

摘要： A multistage relay communication system 100 includes a trunk network 1 and branch networks 2 (2a, 2b), each of which includes one or more communication apparatuses 4. The communication apparatus 4 can switch between a trunk mode to operate in the trunk network 1 and a branch mode to operate in the branch network 2. In the trunk network 1, the communication apparatus 4 carries out fixing of a communication path and redundancy of data based on a path table in order to achieve real-timeness and a data arrival rate. Meanwhile, in the branch network 2, when a communication failure occurs, the communication apparatus 4 autonomously searches for a communication path and constructs a path table, in order to at least secure a data arrival rate even if real-timeness is impaired within an allowable range.

摘要： It is provided a wireless communication system comprising base stations that communicate with a terminal. Each of the base station has antennas. Each of the base stations transmits a first reference signal unique to each of the antennas which does not overlap with another antenna among the base stations at least in a vicinity thereof.

摘要： In a wireless communications system operating according to CDMA or the like, when one terminal simultaneously performs communication using multiple wireless resources (e.g., multiple carriers), there was a problem that when it was attempted to guarantee network mobility by the same soft handoff system as in the case where communication was performed using only one wireless resource, efficiency suffered from the viewpoint of network forwarding load, processing load and wireless resource occupancy time. Soft handoff termination is judged and soft handoff is forcibly terminated according to whether or not the data rate obtained for all resources on the network side satisfies a requested rate, based on a reception state notification from a terminal concerning wireless resources. By performing this processing, the soft handoff period is shortened, sufficient received strength in the terminal is maintained and terminal mobility is guaranteed, while at the same time network forwarding load, terminal processing load and wireless resource occupancy time are suppressed to the absolute minimum.
摘要翻译： 在根据CDMA等操作的无线通信系统中，当一个终端同时使用多个无线资源（例如，多个载波）进行通信时，存在如下问题：当尝试通过相同的软切换系统来保证网络移动性时 在仅使用一个无线资源进行通信的情况下，从网络转发负载，处理负荷和无线资源占用时间的观点来看，效率受到影响。 根据来自有关无线资源的终端的接收状态通知，根据网络侧所有资源获得的数据速率是否满足请求速率，判断软切换终止，并强制终止软越区切换。 通过执行该处理，可以缩短软切换时段，维持终端的接收强度，确保终端移动性，同时将网络转发负载，终端处理负荷和无线资源占用时间抑制到绝对最小。
