一种时分双工系统中应答消息的发送方法及系统
摘要：
一种时分双工系统中应答消息的发送方法及系统，适用于被配置为采用物理上行控制信道(PUCCH)格式3来反馈混合自动重传请求应答消息(HARQ-ACK)的终端中，该方法包括：在绑定窗内接收来自服务小区的物理下行共享信道(PDSCH)；当在该绑定窗内仅接收到主服务小区的一个没有PDCCH的PDSCH和一个下行分配索引值等于1的PDCCH所对应的PDSCH时，按照以下方式之一反馈相应的HARQ-ACK：采用PUCCH格式3反馈相应的HARQ-ACK；采用PUCCH格式1b反馈相应的HARQ-ACK；采用PUCCH格式1b联合信道选择的方式反馈相应的HARQ-ACK。本发明不会对现有协议造成影响。
摘要（英）：

The invention provides a method and system for sending an acknowledgement character message in a time division duplex system, which are suitable for being configured in a terminal for feeding back a hybrid automatic retransmission request acknowledgement character message (HARQ-ACK) by adopting a physical uplink control channel (PUCCH). The method comprises the steps of: receiving a physical downlink sharing channel (PDSCH) from a service cell in a binding window; when one PDSCH without the PDCCH and one PDSCH corresponding to the PDCCH with a downlink allocation index value equal to 1 of a main service cell are received in the binding window, feeding back a corresponding HARQ-ACK according to one of the following modes: feeding back a corresponding HARQ-ACK by adopting a PUCCH format 3, feeding back a corresponding HARQ-ACK by adopting a PUCCH format 1b, and feeding back a corresponding HARQ-ACK by combining a PUCCH format 1b with a channel selection mode. The invention does not influence the traditional protocol.
