Abstract
A user equipment (UE) the UE being configured to receive a message comprising configuration information, CI, indicating that a reference signal, RS, is quasi-co-located, QCL, with a transmission; and adjust a spatial Tx configuration for the transmission based on an RS associated with the received CI.
Claims15
A user equipment (UE), the UE comprising:
- a transmitter for performing uplink (UL) transmissions;
- and
- a receiver for receiving a message comprising configuration information (CI) indicating that a reference signal (RS) is quasi-co-located (QCL) with an UL transmission, wherein the UE is configured to:
- determine a spatial transmit (Tx) configuration for the UL transmission based on the RS associated with the received CI, where the RS is a downlink (DL) RS or an uplink (UL) RS, and
- use the determined spatial Tx configuration to perform the UL transmission, wherein
- if the RS is the DL RS, then the UE determines the spatial Tx configuration based on a spatial receive (Rx) configuration that was used to receive the DL RS, otherwise, the RS is the UL RS, and the UE determines the spatial Tx configuration based on a spatial Tx configuration that was used to transmit the UL RS.

A method performed by a user equipment (UE), the method comprising:
- receiving a message comprising configuration information (CI) indicating that a reference signal (RS) is quasi-co-located (QCL) with an uplink (UL) transmission;
- determining a spatial transmit (Tx) configuration for the UL transmission based on the RS associated with the received CI, where the RS is a downlink (DL) RS or an uplink (UL) RS;
- and
- using the determined spatial Tx configuration to perform the UL transmission, wherein
- if the RS is the DL RS, then the UE determines the spatial Tx configuration based on a spatial receive (Rx) configuration that was used to receive the DL RS, otherwise, the RS is the UL RS, and the UE determines the spatial Tx configuration based on a spatial Tx configuration that was used to transmit the UL RS.
