Wireless communication method for reporting csi values and identifiers
A recently granted patent (Publication Number: US11777576B2) describes a wireless communication method and apparatus for improving signal quality in wireless networks. The method involves receiving a reporting configuration by a communication node, which is associated with a channel measurement resource (CMR) group and an interference measurement resource (IMR) group. Each IMR in the IMR group is associated with different spatial domain filters. The communication node then transmits a report that includes a channel state information (CSI) value, describing the signal-to-interference-plus-noise ratio (SINR). The CSI value is determined by performing channel measurement on a CMR in the CMR group, and the report includes identifiers associated with the CMRs from the CMR group.
Additionally, the method includes obtaining an interference measurement for at least one CSI value based on at least one IMR. The IMR includes a resource for interference measurement. The wireless communication apparatus, which includes a memory and a processor, implements the method by receiving the reporting configuration and transmitting the report. The interference measurement for at least one CSI value is obtained based on at least one IMR, and the IMR includes a resource for interference measurement.
The patent also mentions that at least one CMR and at least one IMR are associated with at least one CSI value. Furthermore, the IMR group in the reporting configuration is associated with the CMR group associated with the reporting configuration.
In summary, the granted patent describes a wireless communication method and apparatus that utilize channel measurement and interference measurement resources to improve signal quality in wireless networks. By performing channel measurement on specific CMRs and obtaining interference measurements based on IMRs, the system can provide accurate channel state information and enhance the signal-to-interference-plus-noise ratio. This technology has the potential to improve the performance and reliability of wireless communication systems.
