摘要： The present invention discloses a method for transmitting data. In the embodiments of the present invention, whether to send blocking information used to block low priority data sent by an upper layer is determined through monitoring a delay of data during transmission, so as to prevent data overflow in a retransmission buffer of the sending end, thus achieving higher INP protection for the low priority data. Meanwhile, only the low priority data is blocked at this time, therefore, a sending end may further continue receiving high priority data, and mark the high priority data with a flag indicating retransmission is not needed when encapsulating the high priority data, so that a receiving end does not apply for retransmission of the high priority data when receiving the high priority data, thus ensuring the short delay requirement of the high priority data.

摘要翻译： 本发明公开了一种发送数据的方法。 在本发明的实施例中，通过监视发送期间的数据延迟来确定是否发送用于阻止由上层发送的低优先级数据的阻塞信息，以防止发送端的重发缓冲器中的数据溢出， 从而为低优先级数据实现更高的INP保护。 同时，此时只有低优先级数据被阻塞，因此发送端可以进一步继续接收高优先级数据，并且在封装高优先级数据时不需要标记指示重传的标志来标记高优先级数据，使得 接收端在接收到高优先级数据时不适用于高优先级数据的重传，从而确保高优先级数据的短延迟要求。
