Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the RSRP measurement period is shortened for multi-receiver chain terminals, then measurement speed and responsiveness are improved, but the complexity of managing measurement cycles and communication scheduling increases
Solution Approach 1:
The measurement process is segmented by receiver chain, with each receiver chain having its own measurement cycle. The base station configures separate measurement cycles for different receiver chains, allowing independent optimization of measurement timing for each chain while managing overall complexity through structured configuration.
Solution Approach 2:
The measurement cycle configuration is made dynamic and adaptable. The base station can configure different measurement cycles based on terminal capabilities, network conditions, and service requirements. This dynamic configuration allows the system to optimize measurement speed while adapting to varying complexity requirements.
2Reliability
If RRM measurements are performed with multi-receiver chains, then measurement accuracy and reliability are improved, but communication interruptions increase
Solution Approach 1:
RRM measurements are performed periodically with configured measurement cycles for each receiver chain. This periodic approach allows measurements to be conducted at optimal intervals without requiring continuous interruption of communication, thereby maintaining reliability while minimizing time loss.
Solution Approach 2:
Measurement configurations and timing are predetermined and configured in advance by the base station. The terminal is pre-configured with measurement cycles and parameters, allowing measurements to be executed efficiently without ad-hoc interruptions to communication.
3Measurement precision
If multiple measurement cycles are managed for multi-receiver chains, then measurement precision and coverage are improved, but scheduling complexity and resource management overhead increase
Solution Approach 1:
Measurement management is segmented by receiver chain, with each chain having dedicated measurement cycles and configurations. This segmentation allows precise measurement management for each chain while the base station maintains overall coordination, distributing complexity rather than centralizing it.
Solution Approach 2:
The system implements feedback mechanisms where measurement results from multiple receiver chains are collected and used to optimize future measurement scheduling. The base station receives measurement reports and adjusts measurement cycle configurations based on observed conditions, improving precision while adapting to actual system state.

AI summary
A disclosure of the present specification provides a method of performing communication by a UE. The method comprises the steps in which: the UE has a capability of receiving a signal by means of a first antenna panel and a second antenna panel, and receives control or data from a first base station through the first antenna panel; and the UE receives a reference signal from a second base station through the second antenna panel to perform radio resource management (RRM) measurement, wherein the UE skips the step of receiving the control or data in an interval of performing the RRM measurement.
