Beamforming assistance

A user equipment (UE) comprising a processor configured to cause the UE to:

• send, to a base station of a wireless communication network, UE capability information indicative of multiple input multiple output (MIMO) related capabilities, the UE capability information being indicative of whether the UE needs to be configured with quasi colocation (QCL) Type D type of QCL by:
• indicating a number of channel state information reference signals (CSI-RS) repetitions per resource set, the indicated number of repetitions indicating whether the UE needs to be configured with QCL Type D type;
• receive, from the base station, configuration information for transmission configuration indication (TCI) state configuration associated to spatial quasi co-location (QCL) assistance, the spatial QCL assistance being a QCL Type D source reference signal (RS) information indicative of whether a first and a second signal is to be received at the UE with the same beam or spatial filter;
• and
• receive, from the base station, physical download control channel (PDCCH) information, to determine a PDSCH scheduling referring to the TCI state.

A method in a base station of a wireless communications network, wherein the wireless communications network provides a radio connection of a user equipment (UE) to the base station, the method comprising:

• receiving, from the UE, UE capability information indicative of multiple input multiple output (MIMO) related capabilities, the UE capability information being indicative of whether the UE needs to be configured with quasi colocation (QCL) Type D type of QCL by:
• indicating a number of channel state information reference signals (CSI-RS) repetitions per resource set, the indicated number of repetitions indicating whether the UE needs to be configured with QCL Type D type;
• determining that the UE needs spatial quasi co-location (QCL) assistance, the spatial QCL assistance being a QCL Type D source RS information indicative of whether a CSI-RS and a PDSCH DMRS signal is to be received with the same beam or spatial filter;
• and
• sending, to the UE, configuration information for a transmission configuration indication (TCI) state configuration associated to spatial QCL assistance.
