摘要： A processing node (10) for a radio telecommunications network (1) comprising an input (11) for radio signals, a receiver (12) arranged to detect radio signals received at the input (11) and a code-detecting circuit (14) coupled to the receiver arranged to determine the presence of any of a first set of codes, typically preamble codes such as those employed in the UMTS system, in the received signal, in which the processing node (10) further comprises an interference-determining circuit (20) coupled to the receiver (12), arranged to perform a comparison of the received signals with a second set of codes that are orthogonal to the first set of codes. This can enable a determination of the impairment covariance in the received signals to be determined, and hence be used to suppress or whiten noise and interference.

摘要： A radio network provides centralized load control in order to control uplink interference in a cell while at the same time permitting adaptation to fast channel variations. The radio network sends to a mobile terminal a percentage of time that the mobile terminal may transmit over a radio channel in the uplink direction to the radio network. The mobile determines a current or future condition of the radio channel and restricts uplink transmissions based on the received percentage and the radio channel condition. Transmissions are restricted to times when the current or future condition is favorable up to the percentage amount. Channel condition favorability may be determined by the mobile station, in one example embodiment, by comparing the radio channel condition to an average condition of the channel, such as a local or moving average channel condition. Also in an example embodiment, the mobile may determine a current or future channel condition using transmit power control commands received from the radio network.

摘要： A signal power associated with a signal received in a current time period is determined. The determined signal power is combined with a predicted effective interference to form a predicted signal-to-interference indicator. The predicted signal-to-interference indicator is compared to a target signal-to-interference indicator. One or more transmit power control commands are generated based on the comparison. In one example embodiment, the predicted effective interference is based on an effective interference estimated for a previous time period. In another example embodiment, the predicted effective interference is based on interference contributions estimated in a current time period and a predicted interference cancellation efficiency. The predicted interference cancellation efficiency is based on the estimated interference cancellation efficiency for a previous time period. The technology is particularly useful in receivers that use interference cancellation and achieves excellent transmit power control performance both in terms of accuracy and speed.

摘要： The present invention relates to an arrangement and a method in a user equipment of saving radio resources in a communication network system comprising a communication network node (15) communicating withto one or more user equipments (18) on uplink (17) and downlink (16) data channels over a radio interface, whereby a transmission power 5 value on said uplink data channel (17) is determined by adding a power offset value to a pre-determined reference power value.

摘要： The present invention relates to methods and arrangements in a wireless communication system, and in particular to uplink outer loop power control. A Node B identifies if a UE from which the Node B receives data is in a predetermined set of power challenged situations. The Node B transmits to the RNC an indication to hold the SIR target of the UE if the UE has been identified to be in a power challenged situation. As a consequence, the uplink outer loop power control (OLPC) procedure in the RNC will not change the SIR target of the UE. This implies that the output power level of the UE remains unchanged as long as the UE remains in the power challenged situation. Thus, user and network performance are improved in the wireless communication system.
摘要翻译：本发明涉及无线通信系统中的方法和装置，特别涉及上行链路外环功率控制。节点B识别节点B从其接收数据的UE是否处于预定的功率挑战情况集合中。如果UE已被识别为处于功率受到挑战的情况，则节点B向RNC发送保持UE的SIR目标的指示。因此，RNC中的上行外环功率控制（OLPC）过程不会改变UE的SIR目标。这意味着只要UE保持在功率受到挑战的情况下，UE的输出功率电平保持不变。因此，无线通信系统中的用户和网络性能得到改善。

摘要： A PCID conflict resolution procedure is implemented with the aid of a user terminal that is capable of detecting and reporting PCID conflicts between two neighboring neighbor cells. A base station in a serving cell configures measurement reporting by user terminals within the cell capable of reporting PCID conflicts. Once measurement reporting by one or more user terminals is configured, the base station will receive measurement reports from the capable user terminals. If a capable user terminal detects a PCID conflict, the user terminal will include an indication of the PCID conflict in the measurement report. When the base station receives a measurement report with an indication of a PCID conflict, the base station implements an autonomous PCID conflict resolution to resolve the PCID conflict.

摘要： A cellular system includes a first cell associated with a first base station, a second cell associated with a second base station, and a mobile radio currently served by the first base station. Distributed resource control may be used in which the first base station alone or in combination with the mobile station makes resource management decisions without having to involve a central controller. In ad-hoc networking, access points can manage resources in a distributed fashion. Relative path gain is determined for an uplink signal from the mobile radio. Relative path gain is based on a comparison of a first path gain related quantity for a mobile uplink signal to the second base station with a second path gain related quantity for the mobile uplink signal to the second base station. Uplink resources in the first cell are managed based on the relative path gain related quantity.
