摘要： The present invention provides a unified, rank independent mapping between antenna ports and group/code pairs. Each antenna port is uniquely associated with one code division multiplexing (CDM) group and one orthogonal cover code (OCC). The mapping between antenna ports and group/code pairs is chosen such that, for a given antenna port, the CDM group and OCC will be the same for every transmission rank.

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 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.
