    • The present invention relates to a method for link adaptation in a wireless communication system. The method comprises: determining whether a UE operates in a SU-MIMO transmission mode or in a MU-MIMO transmission mode; applying, in responsive to determination that the UE operates in the SU-MIMO transmission mode, a SU-MIMO OLLA offset to a signal to interference and noise ratio adjusted with inner loop link adaptation; applying, in responsive to determination that the UE operates in the MU-MIMO transmission mode, a MU-MIMO OLLA offset to a signal to interference and noise ratio adjusted with inner loop link adaptation, wherein the MU-MIMO OLLA offset is based on the SU-MIMO OLLA offset and an extra offset which is indicative of inter-user interference, wherein the SU-MIMO OLLA offset and the extra offset are updated in responsive to receipt of an ACK/NACK message for a packet reported from the UE.
    • 本发明涉及无线通信系统中的链路自适应的方法。 该方法包括:确定UE是以SU-MIMO传输模式还是以MU-MIMO传输模式运行; 在响应于UE在SU-MIMO传输模式中操作的确定的情况下应用针对由内环路适配调整的信噪比和噪声比的SU-MIMO OLLA偏移; 在响应于确定UE在MU-MIMO传输模式中操作的应用中,将MIMO-MIMO OLLA偏移量应用于通过内环路链路自适应调整的信噪比和噪声比,其中MU-MIMO OLLA偏移基于 SU-MIMO OLLA偏移和指示用户间干扰的额外偏移,其中,响应于从UE报告的分组的ACK / NACK消息的接收,SU-MIMO OLLA偏移和额外偏移被更新。

    • Disclosed are a device and a method for low-complexity implementation of a bidirectional arbitrated adaptive decision feedback equalizer in order to transmit messages via channels that are disturbed by intersymbol interference. The equalizer comprises two prefilters (203, 207), each of which is composed of one or two time reversing operations and no or one IIR filter. The two prefilters split a non-minimum phase channel into two time-reverse near-minimum phase channels which are equalized simultaneously in the forward and reverse direction. The SBS arbiter (212) selects, among the two candidate decisions of the two ADFEs, the one that best represents the sampled receive signal.
