Title:
ＭＩＭＯをサポートする無線通信システムにおけるアップリンクでの再伝送制御方法及び装置
Document Type and Number:
Japanese Patent JP5882411
Kind Code:
B2
Abstract:
A method is provided for controlling retransmission by a User Equipment (UE) in a wireless communication system supporting Multiple Input Multiple Output (MIMO) technology. A plurality of transport blocks is initially transmitted to a Node B. A retransmission request for at least one transport block among the plurality of transport blocks is received from the Node B. A precoding matrix is determined based on a number of at least one layer corresponding to the at least one transport block negatively acknowledged (NACKed) from the Node B, if the UE does not receive a Physical Downlink Control CHannel (PDCCH) intended for the UE from the Node B.
