Title: METHOD AND APPARATUS FOR CONFIGURING RANDOM ACCESS RESOURCES AND METHOD AND APPARATUS FOR RANDOM ACCESS
Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method and a device for configuring random access resources and a random access method and a device are provided. The method for configuring random access resources includes: (A) configuring preamble formats for user terminals within a base station coverage according to a carrier frequency range of the base station; (B) configuring physical random access channel resources for the user terminals within the base station coverage; (C) configuring preamble resource pools for the user terminals within the base station coverage; and (D) informing the user terminals within the base station coverage of the configured preamble formats, physical random access channel resources and preamble resource pools. According to the method and the device, proper preamble formats can be configured for the user terminals based on operating frequency bands of the base station so as to satisfy different requirements under different operating frequency bands.
