Abstract
Certain aspects of the present disclosure provide techniques for transmitting simultaneous multi-beams on the same wireless resource. One example method includes determining a set of transmission (TX) beams for simultaneous transmissions to or from a user equipment (UE), signaling to the UE an indication of the TX beams, and transmitting simultaneously via the TX beams.
Claims23
A method of wireless communication by a base station (BS), comprising:
- determining a set of downlink transmission (TX) beams for simultaneous transmissions to a user equipment (UE);
- signaling to the UE an indication of the TX beams, wherein the indication of the TX beams is provided via a virtual transmission configuration indicator (TCI) state indicating a plurality of TCI states corresponding to the TX beams;
- and
- transmitting simultaneously via the TX beams.
1 more element
A method of wireless communication by a base station (BS), comprising:
- signaling, to a user equipment (UE), an indication of a plurality of transmission configuration indicator (TCI) states associated with antenna ports to be used to transmit channel state information reference signals (CSI-RSs) simultaneously via transmission (TX) beams, wherein the indication of the plurality of TCI states is provided via a virtual TCI state;
- and
- transmitting, to the UE, simultaneously the CSI-RSs via the TX beams.
An apparatus for wireless communication, comprising:
- a processing system configured to determine a set of downlink transmission (TX) beams for simultaneous transmissions to a user equipment (UE);
- and
- a transmitter configured to signal to the UE an indication of the TX beams and transmit simultaneously via the TX beams, wherein the indication of the TX beams is provided via a virtual transmission configuration indicator (TCI) state indicating a plurality of TCI states corresponding to the TX beams.
