  • one or a plurality of CSI-RSs that are resources for measuring and reporting CSI to the mobile station UE can be set.
  • the transmission unit 12 uses the bits C 1 to C 7 in the newly defined dedicated MAC-CE signal D to specify the CSI process to report the above CSI. It may be configured to do.
  • the first feature of the present embodiment is a mobile communication method, in which the radio base station eNB transmits subordinate cells # 1 to # 5 when performing CoMP transmission processing (multipoint coordinated transmission processing) in the downlink.
  • the process A for setting the CSI process by the RRC signal for the connected mobile station UE Step B for designating a CSI process to report CSI

Abstract

La présente invention concerne un procédé de communication mobile comprenant : une étape (A) dans laquelle une station de base sans-fil (eNB) définit, au moyen d'un signal RRC, des processus CSI destinés à une station mobile (UE) connectée à une cellule subordonnée; une étape (B) dans laquelle la station de base sans-fil (eNB) indique, dans l'ensemble des processus CSI, un processus CSI devant rapporter le CSI à la station mobile (UE) au moyen d'un signal MAC-CE; et une étape (C) dans laquelle la station mobile (UE) rapporte le CSI au moyen de ressources associées au processus CSI indiqué, à la station de base sans-fil (eNB).
