Abstract

The embodiment of the invention discloses an effective time determination method and device, and the method comprises the steps: receiving system information through at least one system information window in a predefined time domain range, determining the effective time of first information according to a signaling carried in the system information, and enabling a terminal device to determine the effective time of the first information while determining the effective time of the first information, the system information in different system information windows can be combined and received, so that the information transmission efficiency and the information receiving accuracy are effectively improved, the transmission robustness of the communication system is improved, and the system information can be updated under the condition of updating the system information. And the consistent understanding of the network equipment and the terminal equipment on the effective time of the updated system information can be ensured.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and device for determining an effective time. Background technique [0002] With the continuous development of wireless communication technology, satellite communication is considered to be an important aspect of the future development of wireless communication technology. In the scenario of satellite communication, due to the long signal transmission distance between the sender and the receiver, data transmission has a large delay. For transmission with an uplink-downlink relationship, the terminal device can compensate for the transmission delay by using ephemeris information and commonTA (common timing advance, common timing advance) related information. Ephemeris information and common TA information are notified to terminal equipment through system information. [0003] In the related art, the terminal device considers the previously acquir...
