Abstract
The invention refers to a method in a user equipment, UE (100) of a wireless communications network, wherein the communications network provides a radio connection of the UE to a base station, gNB (200), comprising the steps of sending the gNB (200) UE capability information indicative of multiple input multiple output, MIMO, capabilities, receiving from the gNB (200) configuration information for a transmission configuration indication, TCI, state configuration associated to spatial quasi co-location, QCL, assistance, and receiving from the gNB (200) physical download control channel, PDCCH, information to determine PDSCH scheduling referring to the TCI state; the invention further refers to a corresponding method in a gNB, and to a corresponding UE and gNB.

-29. (canceled)
A method in a user equipment (UE) of a wireless communications network, wherein the wireless communications network provides a radio connection of the UE to a base station, comprising:
- sending, to the base station, UE capability information indicative of multiple input multiple output (MIMO) related capabilities;
- receiving, from the base station, configuration information for a transmission configuration indication (TCI) state configuration associated to spatial quasi co-location (QCL) assistance;
- and
- receiving, from the base station, physical download control channel (PDCCH) information to determine a physical download shared channel (PDSCH) scheduling referring to the TCI state.
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;
- receive, from the base station, configuration information for transmission configuration indication (TCI) state configuration associated to spatial quasi co-location (QCL) assistance;
- 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;
- determining if the UE needs spatial quasi co-location (QCL) assistance;
- and
- sending, to the UE, configuration information for a transmission configuration indication (TCI) state configuration associated to spatial QCL assistance.
A base station comprising a processor configured to cause the base station to:
- receive, from a user equipment (UE), UE capability information indicative of multiple input multiple output (MIMO) capabilities;
- determine if UE needs spatial QCL assistance;
- and
- send, to the UE, configuration information for a transmission configuration indication (TCI) state configuration associated to spatial quasi co-location (QCL) assistance.
