摘要： A rake receiver finger assignor is configured to assign a rake receiver finger to a time offset between identified signal path time offsets in accordance with a concentration of identified signal paths from a transmitter to a rake receiver. In accordance with the exemplary embodiment, a number of identified signal paths having time offsets within a time window are observed to determine the concentration of signal paths identified by a path searcher. If the number of identified signal paths indicates a concentrated distribution of signal paths such as during a fat path condition, at least one rake finger is assigned between at a time offset between two identified signal paths.

摘要： The reliability of transmit power control (TPC) commands received from a transmitter is determined based on a TPC target value. The TPC target value is derived based on a TPC threshold and possibly a weight, depending on the receiver implementation. A received TPC command is considered reliable if its absolute value exceeds the TPC target value. Received TPC commands deemed as unreliable are discarded and not used for power control. Multiple TPC target values, used for detecting UP and DOWN commands, may be derived with multiple scaling factors. For a receiver in soft handover and receiving TPC commands from multiple transmitters, a different TPC target value may be derived for each transmitter. The received TPC commands for each transmitter are compared against that transmitter's TPC target value. Received TPC commands deemed as unreliable are discarded and not combined.
摘要翻译：基于TPC目标值确定从发射机接收的发射功率控制（TPC）命令的可靠性。 TPC目标值基于TPC阈值和可能的权重导出，这取决于接收机实现。如果接收到的TPC命令的绝对值超过TPC目标值，则认为它是可靠的。被认为不可靠的TPC命令被丢弃，不用于功率控制。用于检测UP和DOWN命令的多个TPC目标值可以用多个缩放因子导出。对于软切换中的接收机和从多个发射机接收TPC命令，可以为每个发射机导出不同的TPC目标值。每个发射机接收的TPC命令与该发射机的TPC目标值进行比较。被认为不可靠的TPC命令被丢弃并不组合。

摘要： Techniques for reducing the time required for frequency scan in acquisition are disclosed. In one aspect, received power measurements are made at one or more of the possible carrier frequencies and system search is performed on one or more of those frequencies when the power measurement exceeds a threshold. In another aspect, the power is measured at one or more frequencies in a band of frequencies surrounding a frequency at which the measured power exceeded a threshold. If the measured power at one or more of the frequencies in the band exceeds a second threshold, a system search is performed at one or more of those frequencies. In yet another aspect, frequencies meeting certain criteria are sorted in order of measured power prior to system search or further power measurement, and subsequent processing is performed in order of descending measured power. Various other aspects are also presented. These aspects have the benefit of reducing acquisition time, which results in faster system access and allows for more efficient use of system resources.
摘要翻译：公开了减少采集中频率扫描所需时间的技术。在一个方面，在一个或多个可能的载波频率进行接收功率测量，并且当功率测量超过阈值时，对这些频率中的一个或多个进行系统搜索。在另一方面，在测量功率超过阈值的频率周围的频率带中的一个或多个频率处测量功率。如果频带中的一个或多个频率处的测量功率超过第二阈值，则在这些频率中的一个或多个频率处执行系统搜索。在另一方面，满足某些标准的频率在系统搜索或进一步功率测量之前按照测量的功率的顺序进行分类，并且随后的处理按照下降的测量功率的顺序执行。还提出了各种其他方面。这些方面具有减少采集时间的优点，这导致更快的系统访问并且允许更有效地使用系统资源。

摘要： Techniques to more efficiently control the transmit power for a data transmission that uses a number of formats (e.g., rates, transport formats). Different formats for a given data channel (e.g., transport channel) may require different target SNIRs to achieved a particular BLER. In one aspect, individual target BLER may be specified for each format of each data channel. In another aspect, various power control schemes are provided to achieve different target SNIRs for different formats. In a first power control scheme, multiple individual outer loops are maintained for multiple formats. For each format, its associated outer loop attempts to set the target SNIR such that the target BLER specified for that format is achieved. In a second power control scheme, multiple individual outer loops are maintained and the base station further applies different adjustments to the transmit power levels for different formats.

摘要： Techniques are provided to control the transmit power for data transmission on multiple transport channels having different signal quality (SIR) targets. A single SIR target is maintained for all transport channels, and this SIR target is adjusted based only on active transport channels. For each update interval, a data processor processes at least one data block received in the current update interval on at least one of the transport channels and provides the status of each received data block. A controller increases the SIR target based on an up step if any received data block is erased and decreases the SIR target based on a down step if all received data blocks are good. If any received data block is erased, the down step used to adjust the SIR target may be set to the smallest down step size required by all transport channels with erased data blocks.

摘要： Techniques to quickly adjust an SIR target toward a final value needed to achieve a specified target BLER for a data transmission. The outer loop may be implemented with multiple modes. The SIR target may be maintained fixed in a hold mode, adjusted in large down steps to speed up convergence in an acquisition mode, and adjusted by a small down step and a large up step for good and erased blocks, respectively, in a tracking mode. Various schemes may be used to adjust the SIR target by larger down steps in the acquisition mode. These schemes may be used even if data is transmitted intermittently, the target BLER is set to a low value, and/or one or multiple transport channels are used for data transmission. The SIR target may be boosted by a particular amount upon transitioning from the acquisition mode to the tracking mode.
