摘要： The present invention relates to methods and arrangements for providing a more flexible configuration of SRS transmission. This is achieved by dynamically triggering a mobile terminal to transmit SRS. Thus, embodiments of the invention allow dynamically trigged SRS in any uplink subframe, even without necessarily reserving resources semi-statically on cell level. This is done by signaling to the terminal whether the mobile terminal should leave the predefined uplink symbol empty for sounding reference signals or use it for data transmission. In case a terminal leaves the last symbol empty for sounding reference signals, there are two possibilities, either the UE shall transmit one or several reference signals from one or several antennas, or the terminal shall leave the last symbol blank since another terminal may be using the resource for sounding. Accordingly, in a specific embodiment, there are at least three different messages that can be conveyed to the terminal: use the predefined uplink symbol for data, leave it blank or use it for sounding reference signals.
摘要翻译：本发明涉及用于提供更灵活的SRS传输配置的方法和装置。这通过动态触发移动终端来发送SRS来实现。因此，本发明的实施例允许在任何上行链路子帧中动态触发SRS，甚至不必在小区级别上半静态地保留资源。这通过向终端发信号完成，移动终端是否应该将预定义的上行链路符号留空以用于探测参考信号或者将其用于数据传输。在终端将最后一个符号留空以用于探测参考信号的情况下，存在两种可能性：UE应该从一个或多个天线发送一个或几个参考信号，或者终端应该将最后一个符号留空，因为另一个终端可能正在使用侦听资源。因此，在具体实施例中，存在可以传送到终端的至少三个不同的消息：使用预定义的上行链路符号用于数据，将其留空或用于探测参考信号。

摘要： The present invention relates to methods and arrangements in a wireless communication system that enable the use of multi-codeword transmission and ACK/NACK compression with low performance loss. It also enables the use of advanced receivers of reasonable complexity. This is achieved by a solution based on the even distribution of the symbols of separately coded blocks of information bits over the available physical resources before transmission. Each physical resource will thus carry a mixture of symbols from all blocks of information bits, which results in a more similar channel quality for the blocks of information bits. A compressed ACK/NACK message corresponding to the blocks of information bits will thus be more accurate and the performance loss due to the ACK/NACK compression can be reduced.
摘要翻译：本发明涉及无线通信系统中的方法和装置，其能够使用多码字传输和具有低性能损失的ACK / NACK压缩。它还可以使用合理复杂的高级接收机。这是通过基于在传输之前的可用物理资源上的分开编码的信息比特块的符号的均匀分布的解决方案来实现的。因此，每个物理资源将携带来自所有信息比特块的符号的混合，这导致信息比特块的更相似的信道质量。因此，与信息比特块相对应的压缩ACK / NACK消息将更加准确，并且可以减少由于ACK / NACK压缩引起的性能损失。
