Wireless HARQ Feedback Repetition for Random Access Procedures
Summary
Koninklijke Philips N.V. filed patent application US20260100785A1 covering wireless devices and methods for hybrid automatic repeat request (HARQ) feedback repetition in random access procedures. The invention enables devices to dynamically determine repetition numbers for HARQ feedback and preamble transmissions based on reference signal received power thresholds. The application was published on April 9, 2026, with a filing date of December 2, 2025.
What changed
Koninklijke Philips N.V. filed patent application US20260100785A1 for wireless HARQ feedback repetition technology. The invention covers methods for wireless devices to receive RRC messages indicating repetition numbers for HARQ feedback and preamble transmissions, determine RA type and repetition parameters based on RSRP thresholds, and transmit/receive messages accordingly.
For manufacturers of telecommunications equipment and wireless devices, this patent application represents a potential future intellectual property consideration. If granted, the patent would cover specific mechanisms for dynamic HARQ feedback repetition based on signal conditions. Patent applicants should monitor this application for prosecution updates.

Abstract
A wireless device receives radio resource control (RRC) messages indicating repetition numbers for hybrid automatic repeat request (HARQ) feedback for messages of a random access (RA) procedure, and second repetition numbers for transmission of a preamble for the RA procedure. The wireless device determines, for the RA procedure: an RA type from a 4-step RA type and a 2-step RA type, based on a reference signal received power (RSRP) and a first RSRP threshold; and a second repetition number from the second repetition numbers based on the RSRP and one or more second RSRP thresholds. The wireless device transmits the preamble with the second repetition number and receives downlink control information (DCIs): scheduling the messages of the RA procedure; and comprising a bit field indicating a repetition number for the HARQ feedback. The wireless device receives the messages and transmits the HARQ feedback with the repetition number.
