阅读说明：本技术 一种时刻信息的通知方法和装置 (Method and device for notifying time information ) 是由 胡星星 张宏平 曾清海 于 2019-09-30 设计创作，主要内容包括：本申请实施例提供一种时刻信息的通知方法和通信装置,涉及通信领域,能够降低终端设备由于通过RRC消息反馈时延测量的时刻信息时终端设备的处理复杂度。其方法为：终端设备确定服务数据单元SDU的时刻信息,时刻信息指示所终端设备的第一协议层从上层接收到SDU的时刻；终端设备向网络设备发送第一控制协议数据单元PDU,第一控制PDU指示SDU的时刻信息。本申请实施例用于计算网络设备与终端设备之间的上行时延或下行时延。(The embodiment of the application provides a notification method and a communication device of time information, relates to the field of communication, and can reduce the processing complexity of terminal equipment when the terminal equipment feeds back time information measured by time delay through RRC (radio resource control) messages. The method comprises the following steps: the terminal equipment determines the time information of a Service Data Unit (SDU), wherein the time information indicates the time when a first protocol layer of the terminal equipment receives the SDU from an upper layer; and the terminal equipment sends a first control Protocol Data Unit (PDU) to the network equipment, wherein the first control PDU indicates the time information of the SDU. The method and the device are used for calculating the uplink time delay or the downlink time delay between the network device and the terminal device.)
