What changed

The United States Patent and Trademark Office (USPTO) has published a patent application, US20260088948A1, concerning a Type-II coherent joint transmission codebook for 5G networks. The application, filed on November 4, 2022, by inventors Jing DAI, Lei XIAO, Peter GAAL, Mostafa KHOSHNEVISAN, Yu ZHANG, Liangming WU, and Wei XI, outlines methods for user equipment (UE) to manage communication with multiple transmission and reception points (TRPs) using a shared codebook structure. It details how a UE can receive configuration information, measure channel state information reference signals (CSI-RSs) from multiple TRPs, and transmit a report with coefficients for the shared codebook.

This publication represents a new patent application and does not impose immediate regulatory obligations or compliance deadlines on entities. However, it signifies ongoing innovation in 5G technology, particularly in efficient data transmission and reception. Companies involved in developing or deploying 5G infrastructure, user equipment, or related telecommunications technologies should monitor this and similar patent filings as they may influence future standards, product development, and intellectual property landscapes within the industry.

Abstract

Certain aspects of the present disclosure provide techniques for determining coefficients for a codebook to use for coherent joint transmission (CJT) by multiple transmission and reception points (TRPs) transmitting with a same transmit power per TRP. A method that may be performed by a user equipment (UE) includes receiving configuration information indicating resources associated with at least two transmission reception points (TRPs) with which the UE is configured to communicate using a codebook structure with a matrix of coefficients shared between the at least two TRPs; measuring channel state information (CSI) reference signals (CSI-RSs) from the at least two TRPs according to the configuration information; and transmitting a report with coefficients for the matrix of coefficients shared between the at least two TRPs.
