Reciprocity-based beamforming for architecture-aware user equipment
The UE sends UE capability messages to the base station to indicate the supported demodulation mode, which solves the problem of mismatch between the precoding scheme and the demodulation mode between the UE and the base station, and achieves more efficient and reliable wireless communication.

AI Technical Summary
Technical Problem
In wireless communication systems, there may be a mismatch between the precoding scheme and the demodulation mode between the UE and the base station, resulting in poor wireless communication performance.
Method used
The UE capability message is sent to the base station through the UE indicating the supported demodulation mode, the base station precodes based on this information, and the UE demodulates according to the received instructions.
Benefits of technology
The precoding scheme used by the base station is coordinated with the demodulation mode of the UE, and the efficiency and reliability of wireless communication are improved.

Abstract
Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may send a UE capability message to a base station indicating support for at least a first demodulation mode or a second demodulation mode. The first demodulation mode may correspond to a single demodulation process associated with a set of antenna ports at the UE, and the second demodulation mode may correspond to multiple demodulation processes, each process associated with a corresponding subset of antenna ports at the UE. In some cases, the UE may flexibly switch between demodulation modes. The UE may receive one or more downlink signals from the base station via one or more downlink beams based on an indication of the first demodulation mode or the second demodulation mode. The UE may demodulate the one or more downlink signals based on the indicated (e.g., active) demodulation mode.
