Problems solved by technology

[0003] Embodiments of the present invention provide a method for sending and receiving information, a control node, and a terminal to solve the problem that in communication technologies other than the NR Uu interface, NR SSB generation, scrambling, and transmission procedures cannot be used to generate, scramble, and transmit other information. The technical broadcast channel causes incomplete network communication process and cannot guarantee the reliability of communication

Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] When describing the embodiments of the present invention, some concepts used in the following description are explained first.

[0055] 1. New air interface (New radio, NR) physical broadcast channel (Physical Broadcast Channel, PBCH)

[0056] Such as figure 1 shown (where, figure 1 The horizontal line filled box in the box indicates the frequency domain position of NR-PSS transmission, the oblique line filled box indicates the frequency domain position of NR-PBCH and PBCH-DMRS transmission, the grid filled box indicates the frequency domain position of NR-SSS transmission), NR The Synchronization Signal Block (SSB) structure is as follows:

[0057] A11, primary synchronization signal (Primary Synchronization Signal, PSS): m-sequence lengt...

Abstract

The invention provides an information sending and receiving method, a control node and a terminal, and relates to the technical field of communication. The information sending method is applied to the sending end, including: generating first information; sending the first information to the receiving end through a broadcast channel; wherein, the generation method of the first information includes the following one: generated by a physical layer; Generated by higher layers; some information generated by the physical layer and some information generated by higher layers. The above solution defines the generation and transmission process of the broadcast channel of communication technologies other than the NR Uu interface by specifying the information generation method in the broadcast channel, improves the network communication process, and ensures the reliability of network communication.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an information sending and receiving method, a control node and a terminal. Background technique [0002] In addition to the interface between the R15 New radio (New radio, NR) terminal and the network (ie Uu interface), the period, transmission time interval (Transmission Time Interval, TTI) and format of the broadcast channel in subsequent evolution versions or other technologies may be Unlike the NR Synchronization Signal Block (SSB), the NR SSB generation, scrambling and transmission process cannot be directly applied to generate, scramble and transmit broadcast channels of other technologies. Contents of the invention [0003] Embodiments of the present invention provide a method for sending and receiving information, a control node, and a terminal to solve the problem that in communication technologies other than the NR Uu interface, NR SSB generation, scrambling, a...
