Abstract: Embodiments of the present disclosure disclose devices, methods and apparatuses of coherent joint transmission. A terminal device may receive a QCL source configuration from a network device. The QCL source configuration may indicate at least two transmission configuration indication (TCI) states that indicate reference signals from valid QCL sources for a coherent joint transmission (CJT) of tracking reference signals (TRSs). The terminal device may perform a QCL property estimation on received TRSs based on the QCL source configuration.

Abstract: 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.

Abstract: 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.

Abstract: 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.
