Abstract
Methods, apparatuses, and computer-readable medium for DPD are provided. An example method may include receiving, from a base station, an uplink grant associated with one or more resources. The example method may further include transmitting, to the UE via the one or more resources, a DPD training signal at a first port of a plurality of ports. The example method may further include receiving, at a second port of the plurality of ports, the DPD training signal.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive, from a base station, an uplink grant associated with one or more resources;
- transmit, to the UE via the one or more resources, a digital pre-distortion (DPD) training signal at a first port of a plurality of ports;
- and
- receive, at a second port of the plurality of ports, the DPD training signal.
An apparatus for wireless communication at a base station, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- schedule one or more resources as a downlink grant;
- transmit, to the base station via the one or more resources, a digital pre-distortion (DPD) training signal at a first port of a plurality of ports;
- and
- receive, at a second port of the plurality of ports, the DPD training signal.
