INITIAL ACCESS METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240305350 titled 'INITIAL ACCESS METHOD AND APPARATUS

Simplified Explanation

The patent application introduces a method and apparatus for reducing time domain resource overheads of a synchronization signal block (SSB) while ensuring communication efficiency. This is achieved by using a wide beam to send the SSB and a narrow beam for a reference signal (RS) set, which helps in optimizing beam pointing to a user equipment (UE).

An RS set corresponding to an SSB is introduced.
The SSB is sent using a wide beam, while an RS in the RS set is sent using a narrow beam.
The narrow beam training is completed using the RS set to find the optimal beam pointing to a UE.
This method effectively reduces time domain resource overheads of the SSB.

Original Abstract Submitted

an initial access method and an apparatus are provided. in the method, an rs set corresponding to an ssb is introduced. the ssb is sent by using a wideband and a wide beam, and an rs in the rs set occupies a small quantity of time domain resources through frequency division multiplexing and is sent by using a narrow beam. a transmit beam of the rs in the rs set is a refinement of a transmit beam of the ssb. narrow beam training is completed by using the rs set, to find an optimal narrow beam pointing to a ue, so that in the method, time domain resource overheads of the ssb can be effectively reduced while communication efficiency is ensured.
