MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202647081321 A) filed by Qualcomm Incorporated on July 01, 2026, for Techniques For Two-Step Random Access Procedures Using Dedicated Sub- Band Full Duplex Resources.
Inventors include Abdelghaffar, Muhammad Sayed Khairy; Abotabl, Ahmed Attia; Saha, Chiranjib; Ibrahim, Abdelrahman Mohamed Ahmed Mohamed Number; Krishnan, Shankar; Zheng, Ruiming; Phuyal, Umesh; and Kadiri, Prasad Reddy.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more random access channel (RACH) configurations and one or more physical uplink channel (PUSCH) configurations for performing a two-step RACH procedure with the network. The RACH configurations and PUSCH configurations may include common RACH occasions (ROs) and common PUSCH occasions (POs) within half-duplex slots usable by both legacy UEs and full-duplex UEs, as well as full- duplex ROs and full-duplex POs within full-duplex slots (e.g., sub-band full-duplex (SBFD) slots) usable only by full-duplex UEs. The UE may then perform a two-step RACH procedure using the common ROs or the full-duplex ROs, and using either the common POs or the full-duplex POs. The use of full-duplex ROs and full-duplex POs may enable signaling of the two-step RACH procedure to be performed within SBFD slots.
