Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] In the new air interface (NR, New Radio) Rel15, the SSB can be transmitted multiple times in a half frame and numbered in time order. For a specific frequency and subcarrier spacing, it is assumed that the candidate position of the SSB is determined in the half frame. The network device can select the location for sending the SSB according to different situations. Therefore, the actual transmitted SSB is indicated in the system information block...

Abstract

The embodiment of the present invention discloses an SSB transmission indication method, device, terminal, device and medium. The method is applied to a terminal, and the method includes: receiving SSB transmission indication information, and the SSB transmission indication information is used to indicate Candidate temporal positions for SSBs. The embodiment of the present invention can indicate SSB transmission when the time position of SSB transmission is uncertain.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, relate to an SSB transmission indication method, device, terminal, device and medium. Background technique [0002] When the communication system operates in an unlicensed frequency band, before sending information, the terminal or network device needs to perform Clear Channel Assessment (CCA) or extended Clear Channel Assessment (eCCA) to monitor the channel, that is, to perform Energy Detection (Energy Detection, ED), when the energy is lower than a certain threshold, the channel is judged to be empty, and the transmission can start. [0003] Since the unlicensed frequency band is shared by multiple technologies or multiple transmission nodes, this contention-based access method leads to uncertainty in the channel availability time. When the channel is available (available), the transmission position of the signal transmission on the network side may be It...
