MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202537069910 A) filed by Huawei Technologies Co. Ltd., Guangdong, China, on July 23, for 'communication method and apparatus.'
Inventor(s) include Hou, Hailong; Jin, Zhe; and Wen, Ronghui.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "Provided in the present application are a communication method and apparatus, which are used for solving the problem of random access failure caused by the bandwidth of a downlink message exceeding the baseband processing capability of a terminal device. The method comprises: sending a first physical random access channel to a network device; and if a first random access response corresponding to the first physical random access channel is not received within a first random access response time window, sending the first physical random access channel to the network device within a first time period, wherein the duration of the first time period is greater than the duration of a second time period, the second time period is used for a second-type terminal device to perform random access again when a second random access response is not received within a random access response time window, and the second random access response is a random access response corresponding to a physical random access channel sent by the second-type terminal device. Upon random access failure, a physical random access channel is resent within an extended first time period, such that the probability of successful random access can be improved."
The patent application was internationally filed on Dec. 27, 2023, under International application No.PCT/CN2023/142344.
