How to use parameters list from the schema?

Hello. Is there is any way to define the parameters list of the path by extending parameters from the schema?

openapi: "3.0.0"
info:
  title: Demo
  version: 1.0.0

paths:
  /api/v3/places/poi:
    get:
      tags:
        - places
      summary: 'Get POI data'
      operationId: poi
      parameters:
        # This causes an error
        $ref: '#/components/schemas/POIRequest'
      responses:
        '200':
          description: Success

components:
  schemas:
    POIRequest:
      title: 'Points of intereset search request'
      required:
        - lat
        - lng
      properties:
        lat:
          description: 'Point''s latitude'
          type: number
          format: float
          maximum: 90
          minimum: -90
        lng:
          description: 'Point''s longitude'
          type: number
          format: float
          maximum: 180
          minimum: -180
        lang:
          description: 'Prefered language for results'
          type: string
          default: en
          example: ru
      type: object

@erickskrauch Do you maybe mean something like this?

      parameters:
        - in: query
          name: poi
          schema:
            $ref: '#/components/schemas/POIRequest'
          style: form
          explode: true

This is considered a single parameter with an object value, but this object will be sent as individual property=value query parameters in the request URL:

GET /api/v3/places/poi?lat=10&long=20&lang=en

@erickskrauch check out the syntax guide on swagger.io, it has many examples: https://swagger.io/docs/specification/describing-parameters/ https://swagger.io/docs/specification/serialization/
