摘要： A network node and a method for determining a transmission parameter for a transmission to a wireless device. (i) path gain information relating to the wireless device, or (ii) downlink received power relating to Cell-specific Reference Signal(s), CRS(s), transmitted by at least the serving network node, and load information of network nodes that are potentially strong interferers to the wireless device are obtained. A Channel State Information, CSI, report is received from the wireless device, and a CQI offset is determined using (i) the obtained path gain information or (ii) the downlink received power, and the obtained load information. The CQI offset is the difference between a Signal to Interference and Noise Ratio, SINR, for a data signal and an SINR for a CRS. The transmission parameter is based on the reported CSI and CQI offset.

摘要： A method performed by a network node for beam management. The network node receives one or more quality values from a User Equipment (UE). The one or more quality values are measured by the UE on first reference signals transmitted by the network node in respective one or more beams in a first set of candidate beams. The A serving beam is selected out of the first set of candidate beams based on the received quality values for data communication with the UE. The network node creates a rule related to signal quality. The network node obtains one or more second quality values related to respective subsequent messages transmitted to the UE in the selected serving beam. As long as the rule is fulfilled with respect to the second quality value, the network node transmits one or more further subsequent messages only in the serving beam.

摘要： A transmitting node and methods thereinA transmitting node and a method therein for controlling a transmission rank in a wireless communications system. The wireless communications system comprises the transmitting node and a receiving node. The transmitting node is configured to transmit on multiple antennas according to the transmission rank. The transmitting node allocates one or more first transmission resources between the transmitting node and the receiving node to operate according to a first transmission rank, and one or more second transmission resources between the transmitting node and the receiving node to operate according to a second transmission rank. When a performance of the second transmission rank outperforms a performance of the first transmission rank, the transmitting node configures at least one of the one or more first transmission resources to operate according to the second transmission rank.

摘要： A method performed by a network node (110) for estimating a convergence time of interference processing in a user equipment, UE (121), served by the network node (110) in a radio communications network (100) is provided. The network node has at least one Channel State Information, CSI, process configured for the UE. The network node receives, from the UE, at least one first CSI report based on signals transmitted on interference measurement resources of a first CSI process of the UE, wherein the first CSI process is in a first interference state.

After the switch, the network node receives, from the UE, at least one second CSI report based on signals transmitted on the interference measurement resources of the first CSI process of the UE, wherein the first CSI process is in the second interference state. Then, the network node estimates the convergence time of the interference processing in the UE using the received at least one first CSI report and the received at least one second CSI report. A network node (110) for estimating a convergence time of interference processing in a user equipment, a computer program and carrier are also provided.

摘要： A method performed by a network node for configuring interference signal transmissions from transmission points, TPs, in a radio communications network is provided. The network node starts by obtaining estimates indicative of the interference received by one or more wireless devices from the TPs. Then, the network node determines an interference impact value, K, for at least one TP which correspond to the estimates indicative of the interference received by the one or more wireless devices from the at least one TP in relation to the estimates indicative of the interference received by the one or more wireless devices from other TPs of the TPs than the at least one TP. After the determination, the network node configures interference signal transmissions from the TPs based on the at least one interference impact value, K.

摘要： A method in a network node for determining a measure of a downlink interference in a wireless communications network. The downlink interference comprises a first interference in one or more first user equipments in a first cell served by a first base station. The respective interference originates from a second base station when the second base station communicates with one or more second user equipments in a second cell. The network node obtains a first metric representing a count of the second cell as the strongest interfering cell for the one or more first user equipments in the first cell based on a respective information from the one or more first user equipments. The respective information indicates a strongest interfering cell for the respective first user equipment. The network node determines a measure of the downlink interference, based on the first metric.
