Problems solved by technology

However, this method will cause a waste of RO resources, and because the RO corresponds to the access resources in the time domain, it will affect the delay of random access, which is not conducive to meeting the access requirements of low-latency services

Embodiment Construction

[0109] 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.

[0110] figure 1 is a flow chart of a RO configuration method shown in an exemplary embodiment of the present application. This embodiment is described from the base station side, as figure 1 As shown, the RO configuration methods include:

[0111] In step S101, the number of SSBs and the number of ROs currently configured to be sent are determined.

[0112] Wherein, SSB refers to a synchroniz...

Abstract

The present disclosure relates to a method and apparatus for configuring an RO, a random access method and apparatus, a base station, user equipment, and a computer readable storage medium. The methodfor configuring the RO includes: determining the number of synchronous broadcast blocks SSB and the number of ROs sent by the current configuration; sending the number of the SSBs and the number of the ROs to the user equipment UE; determining whether the remainder of the number of ROs divided by the current number of SSBs is greater than or equal to the target number according to the configuration rule, wherein the target number is determined based on the current number of the SSBs; if the remainder is greater than or equal to the target number, establishing a corresponding relation betweenthe remaining number of ROs and the SSBs sent by the current configuration in a one-to-one manner. Embodiments of the present disclosure can reduce RO resource waste and the time delay of and random access.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a random access opportunity (RO) configuration method and device, a random access method and device, a base station, user equipment, and a computer-readable storage medium. Background technique [0002] With the rapid development of wireless communication technology, a fifth generation of mobile communication technology (5th Generation, 5G for short) appears. In the recent 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) discussion, the number of random access opportunities (RO) corresponding to the SSB can be from a fraction less than 1 (for example, 1 / 4 ) to an integer greater than 1 (for example, 4), that is to say, one RO can correspond to multiple SSBs, and one SSB can also correspond to multiple ROs. However, the number of ROs is not always divisible by the number of SSBs. [0003] In related technologies,...
