Problems solved by technology

[0005] Due to the particularity of unlicensed carriers, such as the need to perform LBT before transmission, the transmission of SS / PBCH blocks and / or discovery signals is faced with uncertainty, and is also limited by the rules of unlicensed frequency bands. If the design is not appropriate, it will be serious. Affects the performance of cell search, synchronization and measurement
[0006] For the above-mentioned problems existing in the related art, no effective solution has been found in the related art

Embodiment 3

[0060] This embodiment considers the SS / PBCH block (synchronization / broadcast channel block, referred to as SSB) and / or discovery signal transmission problem in the unlicensed carrier scenario, and improves the SS / PBCH block and / or under the premise of ensuring fairness. Discover signal sending opportunities.

[0061] This embodiment provides a pattern design and / or transmission manner of a signal or channel in an unlicensed carrier, where the signal or channel at least includes an SSB or a discovery signal (DRS, discovery reference signal). Wherein, the composition of the discovery signal includes at least the SSB and one or more other signals or channels. SSB and discovery signals are mainly used for functions such as cell search, time-frequency synchronization and measurement.

[0062] The SS / PBCH block (ie SSB) in this embodiment corresponds to the SS / PBCH block defined in 3GPP TS38.211 / 213-f00. SSB mainly includes PSS, SSS, PBCH and related DMRS, occupying 4 OFDM symbol...

Abstract

The invention provides a signal channel sending method, a base station, a storage medium and an electronic device, and the method comprises the steps: configuring a signal channel which is used for cell searching, synchronization and measurement; and sending the signal channel to a terminal. According to the invention, the technical problem that the discovery signal cannot be fairly sent in the prior art is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method for sending a signal channel, a base station, a storage medium, and an electronic device. Background technique [0002] In related technologies, when NR (New Radio) utilizes unlicensed carriers, it will face many problems. First of all, in some countries and regions, there are corresponding control policies for the use of unlicensed spectrum. For example, a device must perform Listen Before Talk (LBT for short, also known as Clear Channel Assessment (CCA for short)) before using an unlicensed carrier to send data. Only devices with successful LBT can Data is sent on the unlicensed carrier. [0003] For unlicensed carrier operations, the same as licensed carriers, it is first necessary to consider how to perform cell search, synchronization and measurement, and send necessary system information. In the related art, in the NR licensed carrier, the SS / PBCH block (SSB) ...
