摘要： There is provided a base station (BS) (1000) and a method at the BS that is capable of enhancing network capacity with low transmission power in a radio network. The method comprises serving a cell with one or more first carriers. The method further comprises serving a hot-spot within the cell with one or more beam-formed second carriers, wherein the first and second carriers share a total transmission power for serving the cell. Beam-forming based hot-spot carriers can efficiently save transmission power and contribute to the total power utilization efficiency. The base station (1000) thus can meet the capacity enhancement requirement with low transmission power.

摘要： The present invention discloses a network node (100) for multi-user scheduling involving retransmission. The network node comprises a receiver (110) adapted to receive channel quality indicator (CQI) report from a user equipment (UE),an adjuster (120) adapted to adjust signal to interference and noise ratio (SINR) derived from the CQI report to obtain SINR for retransmission, a combiner (130) adapted to combine SINR for initial transmission and SINR for one or a plurality of retransmission to obtain effective SINR, and a scheduler (140) adapted to perform multi-user scheduling on the basis of priority metric derived from the effective SINR. The present invention improves multi-user scheduling by taking HARQ combining gain into account. Instantaneous throughput as well as priority metric can be accurately measured, because SINR from not only channel quality (e.g.CQI) but also HARQ processing gain are both included.

摘要： A method in a receiving node for sending an acknowledgement/not acknowledgement 'ACK/NACK' feedback report of received data units over a radio link is provided. When the receiving node have received (301 ) data units in a number of subframes over a first radio link from a sending node, it creates (302) an ACK/NACK feedback report. The report is compressed such that it comprises one single ACK/NACK feedback relating to the data units in the number of received subframes, and the report comprises an indicator indicating said number of received subframes. The receiving node then transmits (303) the created ACK/NACK feedback report to the sending node over a second radio link. The feedback report renders it feasible for the sending node to decide whether a retransmission of any subframe is required or not based on a comparison of the reported number of received subframes with the known transmitted number of subframes per frame, together with the compressed ACK/NACK feedback report.

摘要： When more than two layers are multiplexed in one CDM group, length-4 OCC has to be used across both clusters in one subframe. This means that slot-by-slot channel estimation according to conventional schemes cannot be exploited and Doppler impact cannot be well overcome. By introducing virtual variables and virtual channel samples that are used in processing two time slots in a subframe independently and applying a frequency domain filter based on the virtual variables and then performing postprocessing based on virtual channel samples, slot-by-slot processing is possible to reduce latency and overcome Doppler impact. Code de- spreading of length-4 OCC is no longer processed in time domain, but in frequency domain with two adjacent CDM subgroups. As a result, the frequency domain filtering can start earlier whereby detection latency and processing time for OCC of length longer than 2 is reduced. It can also be used for the length-2 OCC.
摘要翻译：当一个CDM组中多于两层复用时，必须在一个子帧中跨两个簇使用长度为4的OCC。这意味着根据常规方案的逐时隙信道估计不能被利用，并且多普勒影响不能很好地克服。通过引入用于独立处理子帧中的两个时隙的虚拟变量和虚拟信道样本，并且基于虚拟变量应用频域过滤器，然后基于虚拟信道样本执行后处理，逐个时隙处理是可能的减少延迟并克服多普勒影响。长度为4的OCC的码扩展不再在时域中进行处理，而在频域中具有两个相邻的CDM子组。结果，可以更早地开始频域滤波，从而降低长度大于2的OCC的检测等待时间和处理时间。它也可以用于长度为2的OCC。

摘要： Downlink control information (DCI) extensions to support 3GPP Rel-10 functionalities comprise minimal extensions of DCI format 2B. In some embodiments, only two extra bits (20) are introduced to signal rank up to eight, by reusing the Scrambling Identity bit (16) while at the same time supporting different MU-MIMO dimensioning for the important cases of rank-1 and rank-2. This new DCI format can potentially support not only single cell downlink transmission but also some other Rel-10 functionalities, e.g. CoMP or relaying/HetNet.
摘要翻译：用于支持3GPP Rel-10功能的下行链路控制信息（DCI）扩展包括DCI格式2B的最小扩展。在一些实施例中，通过重新使用加扰标识位（16），同时支持秩-1和重要情况的不同的MU-MIMO尺寸标注，仅引入两个额外的比特（20）来信号等级达到八个 -2。这种新的DCI格式不仅可以支持单小区下行链路传输，还可以支持一些其他Rel-10功能，例如， CoMP或中继/ HetNet。
