Problems solved by technology

Since the time information in the communication system is broadcast by system frame number (System Frame Number, SFN), although the UE can know that the paging message of the UE is at the Kth PO, it still cannot know where the Kth PO is located. The number of the subframe of the frame, causing the UE to be unable to accurately identify the position of the PO

Abstract

The embodiment of the present application discloses a communication method and device. The method includes: the first device acquires the first number of time units included in PO, and the second number of frames included in PF, and the time unit is a subframe or a time slot; A device obtains PO information according to the first quantity and the second quantity; the first device sends a paging message to the second device at the PO indicated by the PO information. By adopting the embodiment of the present application, it is convenient for the second device to accurately identify the position of the PO.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] The base station may send a paging message to a user equipment (User Equipment, UE), and the paging message may be used to notify the UE of receiving a paging request, update system information, or notify the UE of receiving an earthquake, tsunami warning system or commercial mobile warning service. In consideration of energy saving, the paging reception of the UE follows the principle of discontinuous reception (Discontinuous Reception, DRX). In New Radio (NR), the UE is located under the coverage of different beams. In the case where the beam direction of the UE is unknown, in order to ensure that the UE can receive the paging message, the base station can scan the beam ( beam sweep) to send a paging message to the UE, that is, the base station sends a paging message in all beam directions of ...
