QUALCOMM patent: default beams for multi-PDSCH repetitions
Summary
The USPTO has granted QUALCOMM Incorporated a patent (US12587322B2) for techniques related to default beams for multi-PDSCH repetitions in wireless communications. The patent covers methods for user equipment to receive downlink control messages and transmission repetitions, particularly when certain time duration conditions are not met.
What changed
The United States Patent and Trademark Office (USPTO) has issued patent US12587322B2 to QUALCOMM Incorporated. This patent details "Techniques for using default beams for multi-PDSCH repetitions" in wireless communication systems. The core innovation involves methods for user equipment (UE) to manage multiple downlink transmission repetitions of transport blocks, specifically addressing scenarios where a default transmission configuration indicator (TCI) state is used when a specified TCI state fails to meet time duration requirements.
This patent grant is primarily relevant to entities involved in the design and manufacturing of wireless communication hardware and software, particularly those developing user equipment and network infrastructure. While this is a patent grant and not a regulatory rule imposing direct compliance obligations, it establishes intellectual property rights that may influence future product development and licensing in the telecommunications sector. Companies operating in this space should be aware of this patent as it pertains to their technological advancements and potential licensing needs.

Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a downlink control message scheduling multiple downlink transmission repetitions of multiple transport blocks (TBs), the downlink control message indicating a specified transmission configuration indicator (TCI) state for receiving the multiple downlink transmission repetitions according to the scheduling, the multiple downlink transmission repetitions including a first set of downlink transmission repetitions and a second set of downlink transmission repetitions. The UE may be configured to receive, via a default TCI state different from the specified TCI state, a first subset of downlink transmission repetitions from the first set of downlink transmission repetitions, the second set of downlink transmission repetitions, or both, based on a first time interval between a receipt of the downlink control message and a receipt of at least one downlink transmission repetition failing to satisfy a time duration.
