What changed

This USPTO patent application (US20260088961A1) describes a novel approach to managing wireless communication by identifying specific control channel resources for transmitting uplink control information. The invention focuses on user equipment receiving different physical downlink control channel (PDCCH) candidates and subsequently identifying a physical uplink control channel (PUCCH) resource based on control channel element (CCE) indices. This aims to improve the efficiency and reliability of data transmission in wireless networks.

As this is a patent application, it does not impose immediate regulatory obligations. However, companies involved in developing wireless communication technologies, particularly those related to 5G and beyond, should monitor this application and related patents. Successful patenting could lead to licensing requirements or influence future industry standards for network resource allocation and control channel management.

IDENTIFICATION OF CONTROL CHANNEL RESOURCE

Abstract

Aspects relate to transmission of physical uplink control channel (PUCCH) information. A user equipment may receive a first physical downlink control channel (PDCCH) candidate carried by a control resource set that also carries a second PDCCH candidate, where these PDCCH candidates are associated with different aggregation levels. The user equipment may identify a PUCCH resource for transmission of information (e.g., an ACK or a NACK) that is associated with a physical downlink shared channel (PDSCH) transmission scheduled by the first PDCCH candidate. For example, the user equipment may identify the PUCCH resource based on a control channel element (CCE) index that corresponds to a starting CCE of the first PDCCH candidate and the second PDCCH candidate.
