    • A first parameter such as an indicator of modulation and coding scheme MCS for a first shared channel SCH codeword and a second parameter for a second SCH codeword are determined. From a locally stored mapping rule a bit sequence that explicitly indicates the first parameter and that implicitly indicates the second parameter is chosen, and a first control channel CCH codeword is transmitted with the explicit bit sequence that explicitly indicates the first parameter for the first SCH codeword and a second CCH codeword is sent companion to the first CCH codeword, wherein the second parameter for the second SCH codeword is implicitly indicated by the explicit bit sequence of the first CCH codeword. The receiving party determines the second parameter by its own locally stored mapping rule, and an indicator in each CCH codeword may be used to inform the receiver that the two (or more) CCH codewords are associated with one another and to use its mapping rule to determine the second parameter.

    • Disclosed herein are apparatus, methods and computer program products for transmitting signals in different frequency sub-bands used in a particular cell of a cellular wireless communications system in accordance with a power sequence and for selecting modulation schemes to be used in transmitting the signals in the different frequency sub- bands in dependence on signal transmission power allocated to the sub-bands in the power sequence. In the power sequence, signals to be transmitted in at least one sub- band are allocated a higher signal transmission power level than signals to be transmitted in other sub-bands used in the particular cell of the cellular wireless communication system. The differing signal transmission power levels allocated to the different sub- bands typically results in different SINR for signals transmitted at the higher signal transmission power levels and signal transmitted at the lower signal transmission power levels, hi order to reduce the SINR difference between signals transmitted in the different sub-bands, modulation schemes are selected in dependence on the signal transmission power levels allocated to signals transmitted in the sub-bands.
    • 本文公开了用于根据功率序列在蜂窝无线通信系统的特定小区中使用的不同频率子带中发送信号的装置,方法和计算机程序产品,并且用于选择要在传输信号中使用的信号的调制方案 根据分配给功率序列中的子带的信号传输功率,不同的频率子带。 在功率序列中,要在至少一个子带中发送的信号被分配比在蜂窝无线通信系统的特定小区中使用的其他子带中要发送的信号更高的信号发射功率电平。 分配给不同子频带的不同信号传输功率电平通常会导致在较高信号传输功率电平下传输的信号和以较低信号传输功率电平传输的信号的不同SINR。为了减少传输的信号之间的SINR差异 根据分配给在子带中发送的信号的信号传输功率电平来选择不同的子带调制方案。

    • A method, device, computer program product, integrated circuit, and system are described to dispose pilot sequences (for aiding a receiver in estimating a channel) in a frame structure that has subframes of sub-carriers and symbol positions. Locations of common pilot sequences are predetermined, and includes 1) in each subframe, a pilot sequence is disposed in a first symbol position for each of at least two staggered sub-carriers, and 2) in at least one subframe, at least one pilot sequence is disposed in other than the first symbol position and in a sub-carrier other than any of the at least two staggered sub- carriers. Dedicated pilot sequences, whose locations in the frame are not predetermined, are disposed in response to an indication of channel quality received over a wireless link. Common pilot sequences may relate to one or two transmit antennas, and dedicated pilot sequences may enable addition of third and fourth transmit antennas.
