Patent number: 11424851Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications network may operate in accordance with an open-RAN (ORAN) network specification which may support functional splitting between the ORAN distributed unit (O-DU) and the ORAN radio unit (RU) located at a base station. The O-DU may communicate with the O-RU using control messaging, and the O-DU may signal whether various resource block groups are used for data allocation by enabling or disabling bits in a bit mask parameter in a header of the control message. To increase communications efficiency and reduce overhead, the O-DU may dynamically configure the number of bits included in a bit mask based on a radio access technology (RAT) type. The O-DU may determine the size of the bit mask in the control message based on the RAT type and may generate the control message that includes the bit mask.Type: GrantFiled: December 9, 2020Date of Patent: August 23, 2022Assignee: QUALCOMM IncorporatedInventors: Sudeepta Kumar Nath, Tushar Singh, Ashok Kumar Tripathi, Anil Kumar Devpura, Loksiva Paruchuri, Satish Kumar
