Abstract
Wireless communications systems and methods related to wireless communications in a system are provided. A user equipment (UE) may transmit to a base station (BS), an indication of a maximum transmit power capability of the UE. The UE may receive from the BS, a transmit precoding configuration based on the UE's maximum transmit power capability. Additionally, the UE may transmit to the BS, a communication signal using the transmit precoding configuration.
Claims24
A method of wireless communication performed at a user equipment (UE), the method comprising:
- transmitting, to network node, an indication including:
- a single value, including at least a bit value, indicating whether the UE supports full transmit power capability across all bands supported by the UE, and
- a mode indicator, different from the single value, indicating that the UE supports:
- a first mode only, the first mode being associated with the UE supporting full power transmission using full coherent precoders,
- a second mode only, the second mode associated with the UE supporting full power transmission using a virtual port, or
- both the first mode and the second mode;
- receiving, from the network node, a transmit precoding matrix indicator (TPMI) index based on the indication;
- and
- transmitting, to the network node, a communication signal with a power level based on the TPMI index via a delay applied to a baseband signal with transform precoding disabled.

A user equipment (UE), comprising:
- at least one memory;
- and
- at least one processor, coupled to the at least one memory, configured to:
- transmit, to a network node, an indication including:
- a single value, including at least a bit value, indicating whether the UE supports full transmit power capability across all bands supported by the UE, and

- a second node only, the second mode associated with the UE supporting full power transmission using a virtual port, or
- both the first mode and the second mode;
- receive, from the network node, a transmit precoding matrix indicator (TPMI) index based on the indication;
- and
- transmit, to the network node, a communication signal with a power level based on the TPMI index via a delay applied to a baseband signal with transform precoding disabled.
