INDICATING TRANSMISSION CONFIGURATION INDICATOR STATE BASED ON APERIODIC CHANNEL STATE INFORMATION REFERENCE SIGNAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18482234 titled 'INDICATING TRANSMISSION CONFIGURATION INDICATOR STATE BASED ON APERIODIC CHANNEL STATE INFORMATION REFERENCE SIGNAL
The patent application relates to wireless communication technology, specifically focusing on configuring transmission configuration indicator states based on aperiodic channel state information reference signals.
- User equipment (UE) receives a configuration that sets TCI states using AP-CSI-RSs, with each state including an AP-TRS and an AP-CSI-RS.
- The UE gets downlink control information triggering a specific set of AP-CSI-RSs associated with QCL Type-D resources.
- The UE sends a report indicating AP-CSI-RSs and receives an activation command for a TCI state linked to a narrow beam.
- A combination of specific resources uniquely identifies the narrow beam.
- Potential Applications:**
- 5G and future wireless communication systems - Beamforming and beam management in wireless networks
- Problems Solved:**
- Efficient configuration of transmission indicators in wireless communication - Enhanced beamforming capabilities for improved network performance

Original Abstract Submitted
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that configures transmission configuration indicator (TCI) states based at least in part on aperiodic channel state information reference signals (AP-CSI-RSs), where each TCI state includes a first resource that is an aperiodic tracking reference signal (AP-TRS) and a second resource that is an AP-CSI-RS. The UE may receive first downlink control information that triggers a first AP-CSI-RS resource set that includes AP-CSI-RSs that are each associated with a quasi-co-location (QCL) Type-D resource. The UE may transmit a report that indicates one or more AP-CSI-RSs. The UE may receive an activation command that activates a TCI state associated with a first narrow beam, where a combination of a first AP-CSI-RS and a first associated QCL Type-D resource uniquely indicates the first narrow beam. Numerous other aspects are described.
