Title:
制御チャネルリソースを決定するための方法及びユーザ装置
Document Type and Number:
Japanese Patent JP5819524
Kind Code:
B2
Abstract:
The present invention discloses a method and a user equipment for determining a control channel resource. The method includes: detecting a downlink control channel that carries scheduling information of a downlink data channel and is sent by a base station, where the downlink control channel is formed by at least one control channel logical element, and the at least one control channel logical element is mapped to at least one antenna port; acquiring at least one of antenna port information of a first antenna port corresponding to a first control channel logical element of the successfully detected downlink control channel and an offset, and sequence number information of the first control channel logical element; and determining, according to at least one of the antenna port information and the offset, as well as the sequence number information, a first control channel resource used to feed back ACK/NACK information with respect to a downlink data channel corresponding to the successfully detected downlink control channel. By using the method and the user equipment according to embodiments of the present invention, a resource used to feed back the ACK/NACK information can be dynamically determined.
