摘要： A detection strategy is selected for use in detecting a shared control channel that is transmitted on a physical channel in a communication system. This involves using a previously selected detection strategy to detect the shared control channel. The power of the detected shared control channel is measured. At least two correlation results are generated by correlating the measured power with each of at least two parameters that are associated with one or more other physical channels used in the communication system. Based on the at least two correlation results, a detection strategy is selected for upcoming use in detecting the shared control channel.

摘要： A multi-branch OFDM receiver combines diversity signals received over different receiver branches using interference rejection combining. The receiver generates first channel estimates associated with a serving base station, second channel estimates associated with at least one non-serving base station, and a time offset between the serving base station and non-serving base station. The receiver computes a noise covariance matrix based on the second channel estimates and the time offset, and then combines the diversity signals received over different branches using the first channel estimates and the noise covariance matrix.

摘要： A method for estimating a plurality of delay values in a multi-path communication signal. Correlation values are generated that correspond to a plurality of delay values associated with the multi-path communication signal. A first power-delay profile (PDP) sequence is produced from the correlation values and is used to estimate a first delay value. A first reference PDP sequence is generated based on a predefined PDP sequence and the first PDP sequence. The first reference PDP sequence is removed from the first PDP sequence so as to remove at least a portion of the contributions to the first PDP sequence from the first delay value, and to provide a second PDP sequence. A second value is estimated based on the second PDP sequence.

摘要： A method of performing cell measurements in a telecommunications system. The method includes the steps of receiving a signal by a user equipment (UE) operating within the telecommunications system and served by a serving cell, storing the received signal in a buffer, and determining a first portion of the signal related to the serving cell and a second portion related to neighbor (NB) cells. The first portion of the signal is decoded by the Fast Fourier Transforms (FFT) and the signal strength is estimated by a measurement unit coupled to the FFT. Next, any approximately synchronized NB cell signals in the second portion of the signal are then decoded and a signal strength is estimated. It is then determined if sufficient time remains to process unsynchronized NB cell signals of the second portion of the signal. If it is determined that sufficient time remains, the second portion of the signal is played back and decoded using the FFT and a signal strength of any unsynchronized NB cell signals of the second portion of the received signal is estimated.

摘要： A bit error rate estimation is generated for a received signal. This involves using an error correction decoding technique to generate a block of decoded bits from the received signal, and using an error detection technique to determine whether at least one of the decoded bits from the block of decoded bits has an erroneous value. If none of the decoded bits from the block of decoded bits has an erroneous value, then the bit error rate estimate is calculated from the received signal. Otherwise, the bit error rate estimate is set equal to a value that is based on a previously calculated bit error rate. This may be further refined by using a predetermined value in place of a value based on the previously calculated bit error rate if it is detected that a number of consecutively received blocks were received with non-correctable errors.
摘要翻译：针对接收到的信号生成误码率估计。这涉及使用纠错解码技术来从接收信号生成解码比特块，并且使用错误检测技术来确定来自解码比特块的至少一个解码比特是否具有错误值。如果来自解码比特块的解码比特中没有一个具有错误值，则从接收到的信号计算比特差错率估计。否则，将误码率估计值设置为等于基于先前计算的误码率的值。如果检测到多个连续接收的块被接收到具有不可校正的错误，则可以通过使用预定值代替基于先前计算的误比特率的值来进一步细化。

摘要： Methods and apparatus for changing the transmission/reception setup of a base station (BS) in a communication network to another transmission/reception setup (such as one using fewer transmit antennas and/or lower channel bandwidths) without affecting communication with user equipments involve “replacing” the existing BS with a “virtual” BS that has the other transmission/reception setup. Replacement can be performed by, for example, ramping down the power of the existing, or first, BS, which has a respective first cell identification (ID), and simultaneously ramping up the power of the virtual, or second, BS, which has a respective second cell ID.
