摘要： A method and device for controlling a mobile user equipment being in radio communication with base stations of a wireless communication system. The transmit power of the user equipment is controlled by the communication system. Immediately before sending an event message by the user equipment, the transmit power is increased by the user equipment, in order to increase the likelihood that the message is properly received by the base station. The message may be a soft handover event message. The transmit power is increased by opening a closed loop power control circuit, which normally controls the transmit power of the user equipment. By opening the closed loop circuit, the user equipment takes over the control of its transmitted power for increase thereof. Following the sending of the message, the user equipment may control the base station to send with increased power by increasing a target signal-to-interference ratio value (SIR ref ) by means of which the base station power level is controlled. In this way, the likelihood of receiving any acknowledgement messages and event messages from the base station is increased.

摘要： A user equipment (UE) in a mobile communications system is operated in a manner that alleviates or avoids an overload condition in the UE. This involves operating a receiver of the UE to receive one or more data blocks via a channel. In response to a user equipment overload condition being detected, a channel quality indicator (CQI) value is reported to a serving base station, wherein the reported CQI value represents a channel quality that is lower than an actual quality of the channel. The UE is then operated in a manner that is consistent with the reported CQI value. UE overload conditions include overheating, and an inability to process received data blocks at the rate at which they are being received.

摘要： Methods and apparatus that improve interference (Ι) estimation in CDMA systems in which the DPCH is sorted under a scrambling code different from the scrambling code of a channel such as the CPICH are described. In such systems, DPCH Ι-estimation cannot be done by measuring on the CPICH and transforming to the DPCH due to the different interference situations on the two channels. Instead, the DPCH interference is estimated by using knowledge of empty channelization codes in the alternative or secondary scrambling code that can be used for Ι estimation, or using symbols (e.g., control symbols on the DPCCH) on the DPCH, or searching for an empty channelization code and using a found empty code for Ι-estimation.These techniques improve the SIR estimate in comparison to prior techniques and hence also improve the performance of power control, increasing the system’s capacity.
摘要翻译：描述了在CDMA系统中改善干扰（Iota）估计的方法和装置，其中DPCH在不同于诸如CPICH的信道的扰码之类的扰码下排序。在这种系统中，DPCH Iota估计不能通过在CPICH上测量并且由于两个信道上的不同干扰情况而转换到DPCH来完成。相反，通过使用可用于Iota估计的替代或辅助扰码中的空信道化码的知识，或者使用DPCH上的符号（例如DPCCH上的控制符号）或搜索空的信道化代码，并使用发现的空代码进行Iota估计。与以前的技术相比，这些技术改进了SIR估计，从而也提高了功率控制的性能，增加了系统的容量。

摘要： In third generation mobile communications networks, e.g. CDMA systems, a mobile station intending to access a base station transmits a request for access to a base station and waits for a response in the form of an indicator signal. Both detecting a signal as an acknowledgement message without one being sent from the base station and failing to detect such an acknowledgement message can give rise to noise and interference in the whole cell. The invention provides a method and a user equipment for determining the received signal strength in an access slot in a downlink channel and for asserting whether detection of an indicator signal from the base station in the access slot in the downlink channel is reliable. Hereby, a more secure reception of indicator signals can be obtained, which leads to reduced interference and noise in the whole cell.

摘要： Teachings presented herein provide reduced computational complexity and/or memory requirements for a mobile terminal to determine the power backoff required for a multi-carrier uplink signal. In particular, the mobile terminal determines whether its power headroom falls below a pre-defined power headroom threshold, indicating that it is headroom limited. If so, it5 quantizes power allocated to each carrier of the multi-carrier uplink signal according to a pre-defined quantization policy. In doing so, the mobile terminal thereby reduces the possible configurations that may be selected for the multi-carrier uplink signal. Thus, in one embodiment, the mobile terminal stores the required backoff in a look-up table for only the configurations that may be selected when the mobile terminal is headroom limited. This relieves10 the memory requirements of the mobile terminal as compared to storing the required backoff for all possible configurations of the multi-carrier uplink signal.
摘要翻译：本文提出的教学提供了移动终端降低的计算复杂度和/或存储器要求，以确定多载波上行链路信号所需的功率回退。特别地，移动终端确定其功率余量是否低于预定义的功率余量阈值，指示其净空限制。如果是，则它根据预定义的量化策略量化分配给多载波上行链路信号的每个载波的功率。在这样做时，移动终端因此减少了可能为多载波上行链路信号选择的可能配置。因此，在一个实施例中，移动终端仅在移动终端被限制空间时可以选择的配置在查找表中存储所需的退避。与存储针对多载波上行链路信号的所有可能配置的所需退避相比，这减轻了移动终端的存储器要求。

摘要： A technique for improving open loop power control in spread spectrum telecommunications systems is disclosed. In a preferred embodiment, the technique is realized by transmitting at least one first access channel probe for a first message from a mobile station to a base station, wherein the transmission power level of each access channel probe in the at least one first access channel probe is increased until a base station acknowledgment is received for a specific access channel probe of the at least one first access channel probe at a first transmission power level. The first transmission power level is then stored at the mobile station. At least one second access channel probe for a second message is then transmitted from the mobile station to the base station, wherein the transmission power level of an initial access channel probe of the at least one second access channel probe for the second message is based upon the first transmission power level.
