Abstract: When a terminal switches from a downlink subframe to an adjacent uplink subframe, generating a first guard period, where that the terminal does not process any signal in the first guard period is defined, that is, the terminal neither receives downlink data nor sends an uplink signal in the first guard period, and therefore uncertainty of a terminal behavior during a downlink-to-uplink switching process of the terminal is avoided, and successful sending of the uplink subframe can be ensured; and when the terminal switches from an uplink subframe to a downlink subframe, generating a second guard period, where the second guard period overlaps the uplink subframe or the downlink subframe, and that the terminal does not process any signal in the second guard period is defined, and therefore uncertainty of a terminal behavior during an uplink-to-downlink switching process of the terminal is avoided.
Abstract translation: 当终端从下行链路子帧切换到相邻的上行链路子帧时，定义终端不处理第一保护周期中的任何信号的第一保护周期，即终端既不接收下行链路数据也不发送上行链路 信号在第一保护时段中，因此避免了在终端的下行链路到上行链路切换过程期间的终端行为的不确定性，并且可以确保成功发送上行链路子帧; 并且当终端从上行链路子帧切换到下行链路子帧时，产生第二保护周期，其中第二保护周期与上行链路子帧或下行链路子帧重叠，并且终端不处理第二保护周期中的任何信号被定义 因此避免了在终端的上行链路到下行链路切换过程期间的终端行为的不确定性。
