摘要： A front-end module (185) for Time Division Duplex, TDD, with Carrier Aggregation, CA, wherein the front-end module reuses the band selection filters (206, 207) for the aggregated bands and provides switched connections to antenna (1.87, 188, 220) and transmitter/receiver (1.90, 191, 193, 194, 222, 223) according to the Uplink/ Downlink configuration. The use of switches on both the antenna side and the transmitter receiver side of the front-end module enables the reuse of the band selection filters. The front-end module according to the present invention reduces the number of required filters to only one filter for each TDD-CA Component Carrier, CC, band. Thus, the front-end module avoids unnecessary baud selection filters, and thereby also controls the cost of implementation of front-end modules in wireless units operating in the TDD-CA mode.
摘要翻译：一种用于时分双工（TDD）的前端模块（185），其具有载波聚合（CA），其中所述前端模块重新使用所述聚合频带的频带选择滤波器（206,207），并提供到天线（1.87， 188,220）以及根据上行链路/下行链路配置的发射机/接收机（1.90,191,193,194,222,223）。在前端模块的天线侧和发射机接收机侧使用开关使得能够重新使用频带选择滤波器。根据本发明的前端模块将针对每个TDD-CA分量载波，CC，频带的所需滤波器数量减少到仅一个滤波器。因此，前端模块避免了不必要的波特率选择滤波器，从而也可以控制在TDD-CA模式下工作的无线单元中实现前端模块的成本。

摘要： A multi-stage equalizer implementing a low complexity sequence estimation technique referred to as serial localization with indecision (SLI). The multi-stage equalizer includes a plurality of stages including one or more preliminary stages and a final stage. Each stage includes a demodulator that simultaneously equalizes and demodulates an input signal to generate an intermediate sequence estimate comprising a sequence of intermediate symbol estimates. The preliminary stages further include a signal generator to generate the input signal to the next stage. The signal generator includes a modulator to re -modulate the intermediate symbol estimates generated in the same stage and a combiner to subtract the re -modulated symbols from the input signal to generate a residual signal for input to the next stage. The signal generator is not needed in the final stage. A combiner adds the intermediate sequence estimates produced in each stage to produce the final sequence estimate. The combiner may be implemented as a single combiner or as multiple combiners to generate cumulative intermediate symbols estimates at each stage. These intermediate symbol estimates can be used as affective pilot symbols to improve channel estimation for later stages.
摘要翻译：实现低复杂度序列估计技术的多级均衡器被称为具有不确定性的串行定位（SLI）。多级均衡器包括多个级，包括一个或多个初级和最后级。每个级包括解调器，其同时均衡和解调输入信号以产生包括中间符号估计序列的中间序列估计。初级阶段还包括一个信号发生器，用于产生到下一级的输入信号。信号发生器包括用于重新调制在同一级产生的中间符号估计的调制器和组合器，以从输入信号中减去重新调制的符号，以产生用于输入到下一级的残余信号。在最后阶段不需要信号发生器。组合器将在每个阶段产生的中间序列估计值加上以产生最终序列估计。组合器可以被实现为单个组合器或多个组合器，以在每个阶段产生累积中间符号估计。这些中间符号估计可以用作情感导频符号，以改进后期阶段的信道估计。

摘要： RF impairment parameters, including frequency- dependent IQ imbalance, are estimated in a wideband received signal on a per- sub-band (or per sub-band pair) basis. In one embodiment, block- type pilot signals are received, such as on SCH, and IQ imbalance and carrier frequency offset are estimated from the block- type pilot signals. Data and comb- type pilot signals are then received on all sub-bands. Phase noise and channel coefficients are estimated for the first sub-band, based on the IQ imbalance and carrier frequency offset estimates. IQ imbalance is then successively estimated, on a per- sub- band (or per sub-band pair) basis, based on the comb- type pilot signals, the previously estimated carrier frequency offset estimate, and the phase noise and IQ imbalance estimates from prior sub-bands (or pairs). This may comprise iterative estimation based on decision feedback.

摘要： The present invention relates to a method in a receiver for decoding at least two received communication signals, wherein the communication signals are modulated, pre-coded by a discrete Fourier transform and transmitted by means of single-carrier frequency division multiple access scheme (SC-FDMA). The method comprises the steps of : performing an antenna combining and equalization on a signal observed at the receiver; performing inverse discrete Fourier transform on a model of the observed signal; whitening a time domain model of the observed signal; and jointly detecting the received at least two communication signals by performing soft value calculations based on maximum likelihood detection of a whitened time domain model using a whitened time domain channel estimate.

摘要： Methods of operating a first communication node are disclosed. The first communication node communicates by multiple-input-multiple-output (MJMO) wireless communications with a second communication node of a wireless communication system. The method includes receiving a Sounding Reference Signal (SRS) over a plurality of subcarriers transmitted by the second communication node for MIMO communications. Channel quality is measured responsive to the sounding reference signal to output a first channel quality value. A demodulation reference signal is received over a plurality of subcarriers transmitted by the second communication node for MIMO communications. Channel quality is measured responsive to the demodulation reference signal to output a second channel quality value. Reliability of the measurements of the first channel quality value and the second channel quality value is determined. The first channel quality value and the second channel quality value are combined while compensating for the determined reliability difference between the measurements to generate a combined channel quality value. Related communication nodes are disclosed.

摘要： Systems and methods are disclosed for measuring received signal power at a mobile terminal in a cellular communications network in such a manner as to efficiently provide highly accurate received signal power measurements in the presence of strong inter-cell interference. In one embodiment, in order to measure received signal power for a measured cell, a mobile terminal selects weighting parameters for a number of time-frequency samples of a reference signal of the measured cell based, at least in part, on inter-cell interference from one or more synchronized interfering cells and inter-cell interference from one or more non-synchronized interfering cells. The mobile terminal applies the time-frequency samples of the reference signal of the measured cell and the corresponding weighting parameters to corresponding time-frequency samples of a received signal from the measured cell in order to obtain a measurement of the received power for the measured cell.

摘要： Conventional mode adaptation does not account for the gain imbalance between channels for measurement and for data reception. Therefore, the precoder, which is selected based on the measurement channel may not be the optimal precoder for the data reception channel. By maintaining relative SINR ordering between transmission modes, a receiver (110) may select the transmission mode for a transmitter (130) that maximizes the actual throughput even in the presence of inter-antenna gain increase or decrease.
摘要翻译：常规模式适配不考虑用于测量和数据接收的通道之间的增益不平衡。因此，基于测量信道选择的预编码器可能不是数据接收信道的最佳预编码器。通过维持传输模式之间的相对SINR排序，接收机可以选择发射机的传输模式，即使在存在天线间增益增加或减小的情况下也能最大化实际吞吐量。

The method further includes comparing the value, N, to a threshold, wherein if the value, N, is greater than the threshold, mobility pattern information for the UE includes an indication of high mobility, and if the value, N, is less than or equal to the threshold, the mobility pattern information includes an indication of low mobility. The method also includes transmitting machine device capability information, including the indicated mobility pattern information, to be used for determining an adjustment to a resource management procedure for the UE.
