Abstract

Un punto de potencia alta (110) y uno o más puntos de potencia baja (120) transmiten señales que están asociadas con el mismo identificador de celda en un despliegue de celdas heterogéneo. Las áreas de cobertura correspondientes a los puntos de potencia baja (120) caen por lo menos parcialmente dentro del área de cobertura para el punto de potencia alta (110), de modo que las estaciones móviles (130) dentro de un alcance de punto de potencia baja también están dentro del alcance del punto de potencia alta (110), desde una perspectiva de enlace descendente. Las mismas señales de CRS son transmitidas tanto por el (macro)punto de potencia alta (110) como algunos o todos los (pico)puntos de potencia baja (120) . Al mismo tiempo, la red transmite PDSCH basado en CRS para un UE particular tanto en el punto de potencia alta (110) como en algunos o todos los puntos de potencia baja (120). En algunas modalidades, sólo un subconjunto de los puntos, v.gr., aquellos puntos que el UE escucha suficientemente bien, participan en la transmisión de PDSCH usando CRS para estimación de canal.
