DOWNLINK CONTROL INFORMATION DESIGN FOR MULTI-COMPONENT CARRIER SCHEDULING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240137945 titled 'DOWNLINK CONTROL INFORMATION DESIGN FOR MULTI-COMPONENT CARRIER SCHEDULING

Simplified Explanation

The patent application describes methods, systems, and devices for wireless communications, specifically related to transmitting downlink control information (DCI) to user equipment (UE) in a carrier aggregation configuration.

• The base station transmits DCI to the UE indicating a joint field for at least a first component carrier (CC) and a second CC, including indications for rate matching (RM) and zero power channel state information reference signal (ZP-CSI-RS) for both CCs.
• The RM indication may include a common RM resource configuration or per-CC RM resource configurations.
• The ZP-CSI-RS indication may include a set identifier indicating a resource set for ZP-CSI-RS resources for both CCs.

Original Abstract Submitted

methods, systems, and devices for wireless communications are described. a base station may transmit downlink control information (dci) to a user equipment (ue) indicating a joint field for at least a first component carrier (cc) and a second cc of a carrier aggregation configuration. for example, the joint field may include a rate matching (rm) indication for the first cc and the second cc, a zero power channel state information reference signal (zp-csi-rs) indication for the first cc and the second cc, or both. in some cases, the rm indication may include a common rm resource (rmr) configuration applicable for both the first cc and the second cc or per-cc rmr configurations that indicate separate rmrs for each of the ccs. additionally, the zp-csi-rs indication may include a set identifier that indicates a resource set for zp-csi-rs resources for both the first cc and the second cc.
