Abstract

The embodiment of the invention provides a method for sending a synchronization signal block and network equipment, and the method comprises the steps: determining the second transmitting power of other OFDM symbols in an SSB according to the first transmitting power of a target OFDM symbol in the SSB; determining target transmitting power according to the first transmitting power and the second transmitting power; sending the SSB through the target transmitting power. In the method disclosed in the embodiment of the invention, the network equipment determines the second transmitting power ofthe rest OFDM symbols in the SSB according to the first transmitting power of the target OFDM symbol, and determines the target transmitting power according to the first transmitting power and the second transmitting power, so that the transmitting power of the SSB is stable, and the difficulty of detecting the synchronization signal by the terminal is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a method for sending a synchronization signal block and a network device. Background technique [0002] The fifth generation communication technology (5 th generation, 5G) is a representative of the new generation of information technology, which introduces a new architecture and a variety of innovative key technologies. 5G aims to serve three major scenarios, namely, Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communications (URLLC) and massive Machine Type of Communication (mMTC) . Among them, eMBB is the most important application scenario for the initial commercial use of 5G, which provides higher system capacity, higher data throughput rate, more seamless wireless connection, and better user experience. [0003] In 5G New Radio (NR), the terminal (UE) acquires time and frequency synchronization with the serving cel...
