CSI-RS Resource Configuration for Multi-Port Transmission Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in efficiently transmitting channel state information reference signals (CSI-RS) with varying numbers of ports, as current methods fail to accurately reflect spatial position and polarization attributes, leading to inadequate resource utilization and increased overhead.
Innovation Solution
The proposed solution involves configuring CSI-RS resources with specific configuration information, including the number of ports, resource configurations, sequence numbers, aggregation sequence numbers, and a port numbering mode, to enable accurate reflection of spatial and polarization attributes, allowing for efficient transmission of CSI-RS with different port quantities using a single resource overhead.

Engineering Contradiction Analysis
1Quantity of substance
If a CSI-RS with a relatively large number of ports is transmitted using a resource and a part of the transmission signal is taken as a CSI-RS with a relatively small number of ports, then resource overhead is reduced, but the codeword vector in the codebook cannot reflect the spatial position and polarization attribute of the port
Solution Approach 1:
The patent segments the port numbering into different ranges: ports 0-31 use one codeword vector mapping relationship, while ports 32-63 use another codeword vector mapping relationship. This segmentation allows each segment to have its own appropriate codebook, enabling the codebook to accurately reflect spatial position and polarization attributes for both small and large port numbers while using a single CSI-RS resource overhead.
2Quantity of substance
If the same CSI-RS is used as an integral part of the CSI-RS with a relatively large number of ports and also serves as the independent CSI-RS with a relatively small number of ports, then resource overhead is reduced, but transmission requirements of a plurality of CSI-RSs with different numbers of ports cannot be satisfied
Solution Approach 1:
The patent dynamically adjusts the codebook mapping relationship based on the port number. When ports are in the range of 0-31, one mapping relationship is used; when ports are in the range of 32-63, another mapping relationship is used. This dynamic adaptation allows the system to satisfy transmission requirements for different port configurations while using a single CSI-RS resource.
