Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beam measurement methods in massive MIMO systems waste time resources due to inefficient measurement modes that do not consider the maximum measurement capability of User Equipment (UE), leading to prolonged beam training times and reduced data transmission efficiency.
Innovation Solution
A beam measurement processing method that determines completion times for beam sweeping operations, allowing for optimized switching between transmission and reception beams, enabling the UE to perform measurements within non-integral multiples of OFDM symbols, thus maximizing measurement capability and reducing time wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional beam measurement modes are used that do not consider UE measurement capability, then beam measurement can be performed, but time resources are wasted and beam training time is prolonged
Solution Approach 1:
The patent applies dynamics by making the beam measurement process adaptive to UE capability. The network device dynamically adjusts the beam measurement configuration based on the maximum measurement times capability of the UE, allowing the system to optimize measurement scheduling in real-time rather than using fixed conventional modes. This resolves the contradiction by enabling efficient resource utilization without exceeding UE capabilities.
Solution Approach 2:
The patent changes the parameter of measurement scheduling from fixed conventional modes to flexible timing based on completion times. By determining completion times for beam sweeping operations and allowing measurements to complete across non-integral multiples of OFDM symbols, the system optimizes time resource usage while adapting to UE measurement capacity, thereby reducing wasted time resources.
2Device complexity
If beam sweeping is completed within integral multiples of OFDM symbols, then measurement scheduling is simplified, but time resources are wasted due to inability to utilize partial symbols
Solution Approach 1:
The patent segments the beam measurement process into distinct completion time points that are independent of OFDM symbol boundaries. By allowing beam sweeping to complete at any time point rather than requiring alignment with symbol boundaries, the system can utilize partial OFDM symbols for measurements, thereby reducing time resource waste while maintaining manageable scheduling complexity through clear completion time determination.
3Ease of operation
If maximum measurement capability of UE is not considered, then measurement configuration is simpler, but measurement capacity is not fully utilized and time resources are wasted
Solution Approach 1:
The patent implements feedback by having the network device obtain the maximum measurement times capability of the UE and using this information to configure beam measurement operations. This feedback loop enables the system to simplify configuration while fully utilizing UE measurement capacity, as the network device automatically adjusts measurements based on reported UE capabilities without requiring complex manual configuration.

AI summary
A beam measurement processing method and a beam measurement processing device are provided. The beam measurement processing method for a network side device includes: when Beam Pair Link (BPL) quality is measured in a first mode, determining a first completion time at which a beam sweeping for all reception beams has been completed by a User Equipment (UE) corresponding to a current transmission beam, and transmitting a next transmission beam after the first completion time; and/or when the BPL quality is measured in a second mode, determining a second completion time at which a beam sweeping for all transmission beams has been completed by a network side device corresponding to a current reception beam, and performing a next beam sweeping for all the transmission beams after the second completion time.
