Resource allocation for random access preamble based on terminal capability
The patent application (Publication Number: US20230422315A1) describes a terminal apparatus and a base station apparatus designed to optimize the transmission of random access preambles in a wireless communication system. The terminal apparatus includes a processor and memory storing instructions for selecting a resource based on the capability of the apparatus to transmit the preamble. This resource selection ensures efficient communication with the base station apparatus. Additionally, the base station apparatus, equipped with a processor and memory, detects the random access preamble and determines whether to instruct the terminal apparatus to perform repeated transmission based on the selected resource. This control mechanism enhances the connection establishment process in the system.
Furthermore, the patent application outlines control methods and computer-readable storage mediums for implementing the resource selection and transmission processes in both the terminal and base station apparatuses. By specifying distinct resources for different capabilities and optimizing the random access preamble transmission, the proposed technology aims to improve the overall efficiency and reliability of wireless communication systems. The differentiation of resources based on frequency, time, and code usage contributes to better signal quality and connection management between the terminal and base station apparatuses, ultimately enhancing the performance of the communication network.
