通信系统中用于控制数据的子载波分配
摘要：
描述了通信系统中用于控制数据的子载波分配。一种通信系统，其中，用户设备被分配了要在其上向基站发送上行链路数据的子载波。随后由基站在依据用于承载上行链路数据的子载波的子载波上发送针对在上行链路上发送的数据的ACK/NACK消息。优选地使用直接映射功能从上行链路子载波中确定要用于ACK/NACK消息的子载波。在另一个实施例中，优选地通过在用户设备的控制信道中向该用户设备发送一个或多个索引值，在预先对用户设备标识的子载波上向用户设备发送ACK/NACK消息。
摘要（英）：

The invention discloses sub-carrier allocation for control data in a communication system. A communications system is described in which user devices are allocated sub-carriers on which to transmit uplink data to a base station. ACK/NACK messages for the data transmitted on the uplink are then transmitted by the base station on sub-carriers that depend on the sub-carriers used to carry the uplink data. A direct mapping function is preferably used to determine the sub-carriers to be used for the ACK/NACK messages from the uplink sub-carriers. In another embodiment, the ACK/NACK messages are transmitted to the user devices on sub-carriers that are previously identified to the user devices, preferably by transmitting one or more index values to the user device in a control channel thereof.
