User Equipment Capability Reporting for Multi-Carrier Power Class
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accurately distinguishing the specific capabilities of user equipment, particularly when supporting both uplink multiple input multiple output (MIMO) and intra-band contiguous uplink carrier aggregation, leading to inconsistencies in power class reporting.
Innovation Solution
The method involves transmitting uplink signaling from user equipment to a network device, which includes capability indication information related to the power class of the user equipment in multi-carrier transmission. This information allows the network device to accurately determine the radio frequency structure of the user equipment, enabling more precise power configuration and improved transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user equipment transmits capability indication information for power class in multi-carrier transmission, then the network device can accurately determine radio frequency structure and configure power settings, but the signaling complexity and overhead increase
Solution Approach 1:
The capability indication information is segmented into multiple fields: a first field indicating whether the user equipment supports intra-band contiguous uplink carrier aggregation, and a second field indicating whether the user equipment supports uplink MIMO. This segmentation allows the network device to accurately determine the radio frequency structure by interpreting specific field combinations, thereby resolving the contradiction between reporting accuracy and signaling complexity.
2Productivity
If the network device configures power settings based on accurate capability reporting, then transmission efficiency improves, but the user equipment must process and transmit detailed capability information increasing processing overhead
Solution Approach 1:
The user equipment performs preliminary action by pre-configuring and transmitting capability indication information before actual data transmission. This includes setting the first field to indicate support for intra-band contiguous uplink carrier aggregation and the second field to indicate support for uplink MIMO. By doing this in advance, the network device can accurately determine the radio frequency structure and configure appropriate power settings, improving transmission efficiency without requiring complex real-time processing.
3Adaptability or versatility
If the system supports both intra-band contiguous carrier aggregation and uplink MIMO with detailed capability reporting, then the adaptability and versatility of the communication system improve, but the difficulty of detecting and measuring capabilities increases
Solution Approach 1:
The solution applies local quality by assigning specific meanings to specific fields in the capability indication information. The first field locally indicates support for intra-band contiguous uplink carrier aggregation, while the second field locally indicates support for uplink MIMO. The network device detects capabilities by examining these localized field values rather than analyzing the entire capability message, significantly reducing detection difficulty while maintaining high system adaptability.
