Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-frequency wireless cellular networks, the increased path loss due to higher carrier frequencies leads to unreliable data reception and packet loss when multiple terminals access the same beam, reducing data receiving effectiveness.
Innovation Solution
A method and device for data transmission where a terminal receives beam configuration information from a base station, acquires multiple candidate beams, and receives data using these beams, thereby reducing packet loss and improving data receiving reliability.

Engineering Contradiction Analysis
1Area of stationary object
If multiple terminals access the same beam in high-frequency networks, then network coverage is extended, but path loss increases causing unreliable data reception and packet loss
Solution Approach 1:
The patent segments the single beam into multiple candidate beams (first candidate beam, second candidate beam, etc.). Each terminal can be assigned to different beam segments, allowing multiple terminals to access the base station through different beam paths simultaneously, thereby maintaining data reception reliability while extending network coverage area.
Solution Approach 2:
The patent introduces spatial dimensionality by utilizing multiple beams from different directions or angles. Instead of a single-dimensional beam access, terminals can select from multiple beams spanning different spatial dimensions, which diversifies the transmission paths and reduces the impact of path loss on any single terminal.
2Device complexity
If a single beam is used for data transmission, then device complexity is reduced, but data receiving effectiveness decreases due to packet loss
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple candidate beams and their corresponding time-frequency resources before actual data transmission. The terminal performs beam measurement and selection in advance, identifying the best candidate beam from the pre-configured options. This preliminary beam selection process ensures reliable data reception without requiring complex real-time beam management during transmission.

AI summary
A data transmission method includes: receiving beam configuration information sent by a base station; according to the beam configuration information, obtaining a plurality of candidate beams from among a plurality of beams supported by the base station; performing data reception according to the plurality of candidate beams. A plurality of candidate beams can therefore be obtained from among a plurality of beams supported by a base station according to beam configuration information sent by the base station, and thus perform data reception according to the plurality of candidate beams, thereby implementing a multi-beam data reception solution, reducing the probability of packet loss during data reception, and increasing the reliability of data reception.
