Problems solved by technology

[0004] In order to accommodate narrowband access, the physical broadcast channel and the third synchronization signal will be time-multiplexed with the primary synchronization signal and the secondary synchronization signal, so that they will be in the synchronization signal block Occupying more symbols leads to a larger total number of symbols occupied during the beam scanning process, which makes the cell search and measurement process lengthened, which increases the delay and affects the performance of beam training
In addition, more continuous downlink symbols configured in the frame structure will also lengthen the delay of Hybrid Automatic Repeat reQuest (HARQ) feedback, which affects the efficiency of information transmission from the network side to the user equipment side

Embodiment Construction

[0039] Those skilled in the art understand that, as mentioned in the background, in a synchronization signal block (SS-block) of the fifth-generation mobile communication technology (5th-Generation, 5G for short) system, the primary synchronization signal (Primary Synchronization Signal, PSS for short) The secondary synchronization signal (Secondary Synchronization Signal, SSS for short) is time-division multiplexed. Further, in order to support the narrowband access of the user equipment, a physical broadcast channel (Physical Broadcast Channel, PBCH for short) is also transmitted in the synchronization signal block, and may be time-division multiplexed with the primary synchronization signal and the secondary synchronization signal. Similarly, in order to support the narrowband access of the user equipment, a third synchronization signal (Tertiary Synchronization Signal, TSS for short) is also in the synchronization signal block, and may be time-division multiplexed with the pr...

Abstract

A beam scanning sending method, receiving method and device, the sending method includes: configuring a synchronization signal burst set, the synchronization signal burst set includes a plurality of synchronization signal bursts, the synchronization signal burst includes a plurality of A synchronization signal block: sending the synchronization signal burst set at a preset period, wherein the physical broadcast channel and the third synchronization signal multiplex the same group of symbols in the synchronization signal block. The technical solution provided by the invention can reduce the number of symbols in the synchronization signal block, and optimize the time domain positions of the physical broadcast channel and the third synchronization signal in the scanning beam.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a beam sweeping sending method, receiving method and device. Background technique [0002] In the fifth-generation mobile communication technology (5th-Generation, referred to as 5G) system, the synchronization signal block (Synchronization signal block, referred to as SS-block) will include the primary synchronization signal (Primary Synchronization Signal, referred to as PSS) and the secondary synchronization signal (Secondary Synchronization Signal, referred to as SSS). In general, in a sync signal block, the primary sync signal and the secondary sync signal each occupy one symbol [0003] On the other hand, a physical broadcast channel (Physical Broadcast Channel, PBCH for short) is also included in the synchronization signal block; a third synchronization signal (Tertiary Synchronization Signal, TSS for short) can also be included in the synchronization signa...
