アンテナポートモードと送信モードとの移行のための無線通信装置、基地局および方法

Title:

アンテナポートモードと送信モードとの移行のための無線通信装置、基地局および方法

Document Type and Number:

Japanese Patent JP5508554

Kind Code:

B2

Abstract:

A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.
