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.
Claims35
A method of wireless communication by a base station (BS), comprising:
- 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.
A method of wireless communication by a user equipment, comprising:
- receiving, from a base station (BS), an indication of transmission (TX) beams for simultaneous transmissions to or from the UE;
- determining, based on the indication, the TX beams for simultaneous transmissions to or from the UE;
- and
- receiving transmissions based on the indication via one or more reception (RX) beams.
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;
- and
- transmitting, to the UE, simultaneously the CSI-RSs via the TX beams.
A method of wireless communication by a user equipment (UE), comprising:
- receiving, from a base station (BS), 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;
- determining, based on the indication, the TCI states associated with the antenna ports and the CSI-RSs;
- and
- receiving, from the BS, simultaneously the CSI-RSs via one or more reception (RX) beams.
