Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
In the 5G NR system, the granularity of RA preamble configuration may be refined to SSB, that is, the network configures the preamble number corresponding to SSB in addition to the preamble number of non-contention random access, the preamble number of group a, and the preamble number of group B. The parameter SSB-perRACH-occidionandbb-preablesperssb (the specific configuration is shown in fig. 1) gives the number of SSBs corresponding to each RACH occalasion (which can be understood as the time-frequency domain resource for transmitting preambles) and the number of preambles corresponding to each SSB. The number of preambles corresponding to each RACH occision is CB-preamble perssb max (1, ssb-perRACH-allocation).
Based on the design characteristics of the 5G NR system, statistics of corresponding RA preambles are needed to be carried out so as to better optimize PRACH configuration.
Based on this, an embodiment of the present invention provides a measurement method applied to a network device (may be a base station or the like in actual application), as shown in fig. 2, where the method includes:
Step 200: determining a measurement quantity to be measured;

After obtaining the measurement quantity, the network device knows the use condition of the random access resource, so that the random access resource configuration can be optimized. For example, when the random access resource usage rate corresponding to a certain SSB or a certain RACH occalation or BWP or a network slice is not high, the network device may reduce the corresponding random access resource. When the random access resource usage rate corresponding to a certain SSB or a certain RACH occalation or BWP or a network slice is too high, the network device may increase the corresponding random access resource.
