Doctrine Join - 没有名字的关联

I have a problem with join in Symfony Doctrine.
I have a master Entity:

class PosterCartelli{
   ...

   /**
    * @var int|null
    *
    * @ORM\Column(name="id_poster_categoria", type="integer", nullable=false)
    * @ORM\ManyToOne(targetEntity="App\Entity\PosterCategorie", inversedBy="idPosterCategoria")
    * @JoinColumn(name="id_poster_categoria", referencedColumnName="id_poster_categoria")
    */
     private $idPosterCategoria;
    ...
 }

And join with this Entity:

class PosterCategorie{

  /**
   * @ORM\Id()
   * @ORM\GeneratedValue()
   * @ORM\Column(name="id_poster_categoria", type="integer")
   * @ORM\OneToMany(targetEntity="App\Entity\PosterCartelli", mappedBy="idPosterCategoria")
   */
    private $idPosterCategoria;
    ...
  }

My Select in PosterCartelliRepository is:

 return $this->createQueryBuilder('pc')
        ->andWhere('pc.stato = \'Y\'')
        ->join('pc.idPosterCategoria', 'ipc')
        ->orderBy('pc.numeroCartello', 'ASC')
        ->getQuery()
        ->getResult();

But I have always the same error: [Semantical Error] line 0, col 76 near 'ipc WHERE pc.stato': Error: Class App\Entity\PosterCartelli has no association named idPosterCategoria

I tried in different way but I don't have success. I think that everything is correct, because PosterCartelli.idPosterCagoria is declare ManyToOne with "IdPosterCategory" and viceversa.

Can anyone help me, please?
