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

This abstract first appeared for US patent application 18495199 titled 'DOWNLINK CONTROL INFORMATION DESIGN FOR MULTI-COMPONENT CARRIER SCHEDULING

Simplified Explanation

The abstract 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.
• The joint field includes 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 configurations.
• The ZP-CSI-RS indication may include a set identifier 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.
