摘要： A radio network element includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the radio network element to: configure a quasi-co-location-type information entry included in a transmission configuration indication state (S604) for a downlink transmission beam between the radio network element and a user equipment based on at least one beam report, the at least one beam report including at least one transmission parameter for the downlink transmission beam, and the quasi-colocation-type information entry being indicative of one or more sources of inter-beam-interference on the downlink transmission beam at the user equipment; and transmit the transmission configuration indication state including the quasi-co-location-type information entry to the user equipment (S606).

摘要： The specification and drawings present methods and apparatuses for feedback signaling for beamforming purposes in a multiple input-multiple output (MIMO) radio environment. According to an embodiment of the invention, a mobile device is configured to measure an integer number P of different beam groups, each group representing one or more transmit beams and each group corresponding to one or more antenna ports at the mobile device. The mobile device is triggered according to the configuration to provide feedback. The radio access node transmits reference signals on each of the transmit beams across all of the groups for measurement by the mobile device and receives the triggered feedback including, for each of the different beam groups, at least one best match between a transmit beam of the respective group and a corresponding antenna port and an indication of measurement results for the best match.

摘要： Various communication systems may benefit from improved signaling. For example, communication systems may benefit from sending a multi-numerology reference signal that allows a receiving user equipment to perform simultaneous beamforming training, and channel estimation or channel state information acquisition. A method may include receiving at a user equipment a multi-numerology joint reference signal (610). The reference signal may include a reference signal for data channel demodulation or channel state information acquisition, and beamforming training. The method may also include performing simultaneous beamforming training and channel estimation or channel state information acquisition based on the multi-numerology joint reference signal (620).

摘要： Systems, methods, apparatuses, and computer program products relating to physical resource block (PRB) bundling size and/or precoding resource block group (PRG) configuration are provided. One method may include determining a minimum PRG size based at least on a user equipment's operating bandwidth, defining a configurable PRG set based on the minimum PRG size, and signaling the PRG set to the user equipment.

摘要： A mapping is selected, for DMRSs for one or more transmissions on a channel, using information for ranks higher than four that has ports assigned for the DRMSs mapped to different codewords and to different CDM groups. Layers are distributed over the CDM groups. The DMRSs are transmitted on the channel.

摘要： Multi-cell physical uplink shared channel scheduling with sounding reference signal resource sets is provided. The method may include receiving, from a network entity, a first configuration for multi-cell physical uplink shared channel scheduling for a set of cells and receiving a second configuration that includes at least two uplink sounding reference signal resource sets for at least one serving cell of the set of cells. At least two uplink sounding reference signal resource sets may include information relating to usage of codebook and/or non-codebook based physical uplink shared channel transmission. The method also includes receiving a scheduling message indicating to transmit one or more respective physical uplink shared channels on one or more cells, and determining one SRS resource set for the PUSCH transmission including one or more repetitions for the at least one serving cell of the set of cells.

摘要： Example embodiments of the present disclosure relate to methods and apparatuses for codebook-based uplink transmission. A first apparatus obtains a codepoint value and determines at least one table entry for precoding based on the codepoint value. The codepoint value indicates selection of a transmission mode and one or multiple maximum ranks, and at least a maximum rank of a first codepoint value is different from a maximum rank of a second codepoint value. Through this solution, multi-panel simultaneous transmission in the scenarios of single and multiple transmission-reception points (TRPs) can be supported in a simple and easily adoptable way.
