US 2026/0095280 A1 · TECHNOLOGIES FOR COHERENT JOINT TRANSMISSION CODEBOOK

Abstract

The present application relates to devices and components including apparatuses, systems, and methods for coherent joint transmission (CJT) codebook reporting. For example, techniques are described for determination of CJT codebook feedback with phase offset compensation. Additionally, techniques are described for associating an offset report of phase, frequency, and/or time offset with a CJT codebook report.

Claims20

Dependent claims

An apparatus comprising:

processing circuitry to:
identify an association between a coherent joint transmission (CJT) codebook report and an offset report, wherein the offset report indicates offset values corresponding to respective channel state information-reference signal (CSI-RS) resources;
generate, in accordance with the association, CJT codebook feedback based on the offset values;
and
encode the CJT codebook report for transmission, the CJT codebook report to include the CJT codebook feedback;
and
interface circuitry coupled to the processing circuitry to enable communication.
