Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the base station performs beam indication to the relay node by indicating a combination of beam information and time resource set, then spatial directivity of forwarding by the relay node is improved, but beam indication conflict occurs and operation confusion of the relay node increases
Solution Approach 1:
The patent segments the time resource set into multiple time resources and associates each time resource with specific beam information. The relay node determines its state based on the correspondence between time resources and beam information, avoiding conflicts by clearly defining which beam to apply in each time resource.
Solution Approach 2:
The base station pre-configures the time resource set and beam information associations before beam indication. The relay node receives and stores this configuration in advance, so when beam indication is performed, the relay node can directly determine its state without confusion by referencing the pre-established correspondence.
2Measurement precision
If multiple beam information and time resource sets are indicated, then beam indication accuracy is improved, but power consumption of the relay node increases
Solution Approach 1:
The relay node processes only the beam information and time resource set correspondence that is relevant to the current time resource being served. It does not need to continuously process all possible beam information combinations, reducing computational overhead and power consumption while maintaining accurate beam indication.
Solution Approach 2:
The beam indication is performed periodically with the time resource set, and the relay node determines its state periodically based on the current time resource's associated beam information. This periodic operation reduces continuous processing requirements and associated power consumption.
3Measurement precision
If beam information and time resource sets are indicated together, then spatial directivity is improved, but signaling overheads increase
Solution Approach 1:
The patent merges the beam information indication with the time resource set indication into a single signaling process. The base station indicates both beam information and time resource set together, and the relay node determines state by the correspondence between them, reducing the need for separate signaling messages and lowering overall signaling overhead.
4Measurement precision
If multiple beam information and time resource sets are indicated, then spatial directivity is improved, but transfer delay increases
Solution Approach 1:
The correspondence between time resources and beam information is pre-configured and stored in the relay node before actual beam indication is needed. When beam indication is performed, the relay node can immediately determine its state by referencing the pre-established correspondence, avoiding time-consuming processing and reducing transfer delay.
