摘要： The embodiments relate to a method and a base station (110) for interference management in a cellular network (100) employing Space-Division uplink (UL) downlink (DL) Duplexing (SDD). The base station (110) assigns a plurality of Remote Radio Units (RRU) as Tx RRUs operable to dedicatedly transmit downlink signals to a plurality of UEs and Rx RRUs operable to dedicatedly receive uplink signals from the plurality of UEs at the same frequency band and same time as the transmission of the Tx RRUs. The base station then suppresses the interference caused by simultaneous transmission on the same frequency band by using a Tx spatial beamforming weighting matrix and a Rx spatial beamforming weighting matrix. In addition, the base station may perform cross-talk cancellation on the residual interference contained in the received signals by using the knowledge of the downlink traffic data.

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： In some embodiments, a method is provided in a radio network node for transmitting a reference signal over an antenna port, wherein the reference signal is transmitted in a code division multiplexing, CDM, group. The CDM group comprises at least two CDM subgroups, each CDM subgroup being transmitted on a different subcarrier. Each CDM subgroup comprises resource elements. In a first step, the radio network node transmits the reference signal over a first CDM subgroup using an orthogonal cover code. The first CDM subgroup comprises resource elements in a first time slot and a subsequent time slot. In a further step, the radio network node transmits the reference signal over a second CDM subgroup using a permutation of the orthogonal cover code. The second CDM subgroup comprises resource elements in the first time slot and the second time slot. The permutation of the orthogonal cover code is selected in such a way as to enable decoding of the reference signal in the frequency domain, by applying the orthogonal cover code only to resource elements in the CDM group which are comprised in the first time slot.
