Abstract

The present invention discloses a method and device for determining resources. The method includes: determining the correlation between a target signal and a physical random access channel transmission opportunity RO resource according to a preset rule, and the target signal includes a synchronization signal block SSB or Channel State Information Reference Signal CSI‑RS. Through the method for determining resources disclosed in the present invention, according to setting preset rules, terminal devices or network devices can determine the association relationship between target signals and RO resources according to the above preset rules. In addition, after determining the association relationship between the target signal and the RO resource, the terminal device can determine the RO resource for initiating random access according to the association relationship, and initiate random access on the determined RO resource, which is convenient Improve the success rate of random access.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource determination method and device. Background technique [0002] In the new radio (New Radio, NR), the terminal device can transmit a preamble (preamble) code according to the configured physical random access channel transmission occasion (PRACH transmission occasion, which can also be written as PRACH occasion, referred to as RO resource). At a time point (time instance, that is, the time domain position of an RO), there may be multiple ROs performing frequency division multiplexing (Frequency-division multiplexing, FDM), and an RO performing FDM at a time point (time domain position) The number of can be: {1, 2, 4, 8}. There is an association relationship between the RO and the synchronization signal block SSB, and the number of SSBs associated with an RO may be: {1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, 16}. Alternatively, there may be an association relationship between the RO...
