摘要： A method in a radio network node for transmitting a reference signal over an antenna port includes transmitting the reference signal over a first code division multiplexing (CDM) subgroup using an orthogonal cover code. The first CDM subgroup includes a first set of resource elements in a first time slot and a second set of resource elements in a subsequent time slot. The radio network node selects a permutation of the orthogonal cover code and transmits the reference signal over a second CDM subgroup using the permutation. The second CDM subgroup includes a third set of resource elements in the first time slot and a fourth set of resource elements in the subsequent time slot. The permutation is selected to enable decoding of the reference signal in the frequency domain, by applying the orthogonal cover code to the first set resource elements and to the third set of resource elements.

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.

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.
