Abstract
Certain aspects of the present disclosure provide techniques for scaling transmission power across transmit chains for physical uplink shared channel (PUSCH) transmissions.
Claims30
A method of wireless communications by a user equipment (UE), comprising:
- determining a transmit power budget and an allocation of the transmit power budget across transmit chains for a scheduled physical uplink shared channel (PUSCH) transmission according to a plurality of power scaling factors;
- transmitting, to a network entity that scheduled the PUSCH, a power headroom report (PHR) including the plurality of power scaling factors;
- and
- transmitting the PUSCH using the transmit chains according to the allocation of the transmit power budget.
1 more element
A method of wireless communications by a network entity, comprising:
- scheduling physical uplink shared channel (PUSCH) transmissions from a user equipment (UE);
- receiving a power headroom report (PHR) including a plurality of power scaling factors used by the UE to allocate transmit power budgets across transmit chains of the UE for the PUSCH transmission;
- and
- using the plurality of power scaling factors to select one or more parameters for scheduling subsequent transmissions from the UE.
1 more element
An apparatus for wireless communications by a user equipment (UE), comprising:
- at least one processor configured to determine a transmit power budget and an allocation of the transmit power budget across transmit chains for a scheduled physical uplink shared channel (PUSCH) transmission according to a plurality of power scaling factors;
- and
- a transmitter configured to:
- transmit, to a network entity that scheduled the PUSCH, a power headroom report (PHR) including the plurality of power scaling factors;
- and
- transmit the PUSCH using the transmit chains according to the non uniform allocation of the transmit power budget.
3 more elements
An apparatus for wireless communications by a network entity, comprising:
- at least one processor configured to schedule a physical uplink shared channel (PUSCH) transmission from a user equipment (UE);
- and
- a receiver configured to receive a power headroom report (PHR) including a plurality of power scaling factors used by the UE to allocate transmit power budgets across transmit chains of the UE for the PUSCH transmission, wherein the at least one processor is further configured to use the plurality of power scaling factors to select one or more parameters for scheduling subsequent transmissions from the UE.
