Embodiment Construction
[0070] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0071] In order to solve the access requirements of systems with a large high-frequency range, the embodiments of the present disclosure include different strategies for indicating random access in the configuration information, that is, the first strategy can be used for relatively low-frequency systems, and the relatively high-frequency The system can adopt the second strategy (low frequency a...

The present disclosure relates to a random access method and device, user equipment, and a computer-readable storage medium. Among them, the random access method includes: determining the strategy adopted by the current UE random access according to the received configuration information, the configuration information includes different strategies used to indicate random access; determining the uplink physical random access strategy corresponding to the adopted strategy Access channel PRACH resources; send a preamble sequence to the base station based on the determined uplink PRACH resources. In this disclosure, by including different strategies for indicating random access in the configuration information, the UE can determine the strategy adopted by itself for random access according to the received configuration information, and determine the uplink PRACH resource corresponding to the adopted strategy, and then The preamble sequence is sent to the base station based on the determined uplink PRACH resource, which satisfies the configuration requirements and access requirements of the system with a large high-frequency range.
Description
technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a random access method and device, user equipment, and a computer-readable storage medium. Background technique [0002] In the fourth generation mobile communication technology (4h Generation, 4G for short) system, the random access process is based on omnidirectional transmission of uplink and downlink signals, and the user equipment (UE) only needs to select appropriate resources according to the system information, and use this resource Randomly select a preamble sequence (preamble) to initiate random access. [0003] However, for a system with a large high-frequency range, the aforementioned random access method cannot well meet the access requirements. Contents of the invention [0004] In view of this, the present application discloses a random access method, device, device, and computer-readable storage medium, so as to solve the configuration an...
