Non-competitive random access resource allocation method, base station and storage medium

Abstract

The invention discloses a non-competitive random access resource allocation method, a base station and a storage medium. The method comprises the following steps: receiving an allocation request of non-competitive random access resources of user equipment, scheduling idle non-competitive random access resources according to the allocation request, and allocating the idle non-competitive random access resources to user equipment. According to the scheme, when a plurality of SSBs are mapped to one RO, due to the fact that the number of the non-competitive random access resources is relatively small, the problem that distribution of the non-competitive random access resources fails in some scenes or functions, time delay becomes long, and even the functions are unavailable is solved, the distribution failure probability of the non-competitive random access resources can be reduced, and the utilization efficiency of the non-competitive random access resources is improved.

Description

technical field [0001] The present application relates to the field of wireless communication, and in particular to a method and a base station for allocating non-contention random access resources. Background technique [0002] In 5G, each cell has 64 available preamble (random access preamble) sequences, one of which is selected by UE (User Equipment, user equipment) or designated by gNB (gNodeB, 5G NR base station) in PRACH (Physical Random Access Channel, physical random access channel) transmission. These 64 preamble sequences can be divided into three parts, one part is used for contention random access, one part is used for non-competition random access, and the other part is reserved for other scenarios, such as Request OSI (request OSI). [0003] The high-level parameter ssb-per-RACH-Occasion indicates that ssb-per-RACH-Occasion (hereinafter referred to as N) SSB (Synchronization Signal Block, synchronization signal block) is mapped to a RO (Random AccessChannel Oc...

AI Technical Summary

Problems solved by technology

[0006] This application provides a method, base station, and storage medium for allocating non-competitive random access resources, so as to at least solve the problem of some scenarios caused by the relatively small number of non-competitive random access resources when multiple SSBs are mapped to one RO. Or the non-competitive random access resource allocation failure under the function, resulting in longer delay or even unavailable function
