Beam Sequence Configuration for Wireless Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beam indication methods in wireless communication systems result in high signaling overheads, particularly in scenarios where terminal devices move regularly, leading to wastage of signaling resources.
Innovation Solution
Configuring and sending beam sequence information to terminal devices, which includes identification information for multiple beams, periodicity, and transmission moments, allowing network devices and terminal devices to synchronize signal transmission based on pre-defined sequences, thereby simplifying the beam indication process and reducing signaling overheads.

Engineering Contradiction Analysis
1Reliability
If beam indication is performed once at each location at which uplink and downlink data are sent and received, then communication reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring beam sequences and their corresponding identification information before actual communication occurs. The network device configures multiple beam sequences with different periodicities in advance, and the terminal device selects appropriate beams based on its movement pattern without requiring continuous beam indication signaling during data transmission.
Solution Approach 2:
The patent utilizes periodic action by introducing beam sequences with different periodicities (first periodicity and second periodicity) that correspond to different terminal device movement patterns. The terminal device selects a beam sequence based on whether its movement periodicity matches the first or second periodicity, thereby adapting beam indication to the actual communication needs and reducing unnecessary signaling.
2Measurement precision
If conventional beam indication manner is used for regularly moving terminal devices, then beam alignment accuracy is improved, but signaling resource utilization deteriorates
Solution Approach 1:
The patent applies dynamics by making the beam indication system adaptive to terminal device movement characteristics. The terminal device dynamically selects between different beam sequences (with different periodicities) based on its movement pattern, and the network device dynamically determines which beam sequence to use based on feedback or pre-agreed rules, thereby optimizing signaling resource usage while maintaining beam alignment accuracy.
Solution Approach 2:
The patent utilizes parameter changes by varying the periodicity parameter of beam sequences to match different terminal device movement patterns. The system configures at least two beam sequences with different periodicities, and the terminal device selects the appropriate sequence based on whether its movement periodicity corresponds to the first or second periodicity, thereby changing the beam indication parameters to suit the actual communication scenario.

AI summary
An information transmission method comprising configuring, by a network device, first beam sequence information, where the first beam sequence information indicates a plurality of pieces of first identification information, and where each of the plurality of pieces of first identification information indicates one beam that carries a transmission signal, sending, by the network device, the first beam sequence information to a terminal device, and performing, by the network device, signal transmission with the terminal device using the beams indicated by the plurality of pieces of first identification information.
