摘要： In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be.

摘要： The invention relates to a method and an arrangement for obtaining efficient radio resource utilization in a communication network comprising a communication network entity transmitting data on a downlink channel over a radio interface to one or more user equipments, each of which is transmitting data on an uplink channel to said communication network entity over said radio interface. The communication network entity receives transmit power control (TPC) commands on said uplink channel and, further, monitors a channel quality indicator (CQI) on said uplink channel from said user equipment in order to obtain channel quality indicator measurements. If there is a channel quality indicator available, the communication network entity calculates a required downlink power. Otherwise, the communication network entity decodes said received transmit power control commands. Thereafter said transmission power is adjusted either based on the calculated downlink power or based on the decoded transmit power control commands in order to obtain efficient radio resource utilization.

摘要： The signalling overhead in cellular communication systems such as OFDMA is reduced by calculating a report value as a function of each measurement value that is to be reported from a user terminal to the network. The report value is preferably based on a maximum value for the parameter measured, and can be represented by fewer bits than the measurement value. The overhead may be further reduced by selecting only the best measurement values for reporting from the user terminal to the network.

摘要翻译： 通过计算作为从用户终端向网络报告的每个测量值的函数的报告值来减少诸如OFDMA的蜂窝通信系统中的信令开销。 报告值优选地基于所测量的参数的最大值，并且可以由比测量值更少的比特来表示。 可以通过仅选择用于从用户终端向网络报告的最佳测量值来进一步降低开销。

摘要： Out-of-sync and in-sync detections and downlink power control by UTRAN user equipment are improved in Continuous Packet Connectivity mode featuring discontinuous UL DPCCH transmission by requiring all F-DPCH transmissions from a base station to the user equipment to be valid during a UL DTX gated period. Additionally, the user equipment receives and considers all F-DPCH transmissions during the UL DTX gated period, for power control, out-of-sync and in-sync detections. If the user equipment detects an out-of-sync condition, it may immediately transmit a scheduling request to notify the network, temporarily or permanently annulling the discontinuous UL DPCCH transmission.
