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： Improved ACK/NACK detection in a mobile terminal of a wireless communication system is disclosed. The ACK/NACK detection uses knowledge about the power of the acknowledgment/negative acknowledgment signal along with the probability that a DTX will occur to increase the probability that the ACK signal will be correctly detected. The probability that a DTX will occur is determined by observing the transmit power commands issued to the mobile terminal. A high number of power up commands relative to power down commands may indicate a poor quality uplink meaning that a DTX is likely to occur.

摘要： A cell searching procedure is modified to enable a user terminal to determine whether a detected signal originates in a known cell or a new cell having the same cell identifier as the known cell. When a signal is detected, the user terminal determines the cell identifier and timing of the detected signal. If the cell identifier matches a known cell and the timing is outside the timing window of the known cell, the user terminal compares detected signal with a corresponding received signal received from the known cell having the same cell identifier as the detected signal source. The user terminal determines, based on said comparison, whether the detected signal is from the known cell or a new cell.

摘要： A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.
