Set Based Beam Reporting for Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies, such as LTE and NR, face challenges in optimizing beam reporting for accurate channel and interference measurements, leading to suboptimal transmission quality due to the lack of comprehensive cross-beam interference consideration.
Innovation Solution
The method involves the base station providing sets of candidate beams to user equipment, where each set includes two beam combinations: one for channel measurement and another for interference measurement, allowing the equipment to report measurement values that account for cross-beam interference, thereby improving decision-making and transmission quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional single-beam measurement reporting is used, then the measurement process is simple, but the transmission quality is suboptimal due to lack of cross-beam interference consideration
Solution Approach 1:
The patent segments the beam measurement process into multiple candidate beam combinations within sets, where each set contains multiple beam pairs. This segmentation allows the system to evaluate different beam combinations independently and select the optimal set, improving transmission quality by considering cross-beam interference while maintaining manageable measurement complexity through structured organization of candidate beams.
2Reliability
If comprehensive beam measurement sets are reported, then transmission quality improves, but processing and signaling resources are wasted on unsuccessful transmissions
Solution Approach 1:
The patent applies preliminary action by having the base station pre-configure multiple sets of candidate beam combinations before actual transmission. The UE measures and reports on these pre-configured sets, allowing the base station to identify and select the optimal beam set in advance. This preliminary measurement and reporting process prevents resource wastage by ensuring that only promising beam combinations are selected for actual data transmission, thereby improving transmission quality while avoiding energy loss on unsuccessful transmissions.
3Measurement precision
If multiple beam combinations are measured for cross-beam interference, then measurement precision improves, but the quantity of measurements increases
Solution Approach 1:
The patent segments the large number of beam measurements into organized sets of candidate beam combinations. Each set contains multiple beam pairs that are measured together to evaluate cross-beam interference. This segmentation approach improves measurement precision by systematically evaluating interference relationships between beams while managing the quantity of measurements through structured set organization, where the base station can configure multiple sets but the UE measures them in an organized manner.

AI summary
Various aspects of the present disclosure generally relate to techniques for set based beam reporting. In some aspects, a user equipment (UE) may receive, from a base station, an indication of one or more sets of candidate beams, where each set of candidate beams includes a first beam combination and a second beam combination. The first beam combination may include a first beam as a channel measurement resource (CMR) and a second beam as an interference measurement resource (IMR), and the second beam combination may include the second beam as a CMR and the first beam as an IMR. The UE may determine measurement values for beam combinations in the sets and determine a candidate set to report based at least in part on the measurement values. The UE may transmit a measurement report with measurement values for the first and second beam combinations of the candidate set.
