DYNAMIC ANTENNA ADAPTATION IN SECONDARY CELL DORMANCY - A simplified explanation of the abstract

This abstract first appeared for US patent application 17546746 titled 'DYNAMIC ANTENNA ADAPTATION IN SECONDARY CELL DORMANCY

Simplified Explanation

Methods, systems, and devices for wireless communications are described in this patent application. The innovation focuses on improving the channel state information (CSI) reporting process in a wireless network. Here are the key points:

  • User equipment (UE) receives signaling from a base station indicating a CSI report configuration.
  • The CSI report configuration specifies the mapping between CSI reference signal (CSI-RS) resources for dormant secondary cells and the antenna panel configuration of the base station.
  • Based on this configuration, the UE receives one or more CSI-RSs on the specified CSI-RS resources of the dormant secondary cells.
  • The UE may also receive an antenna adaptation indication by monitoring a downlink control channel or through scheduling information for a downlink shared channel.
  • The UE then transmits a message reporting CSI feedback to the base station according to the received antenna adaptation indication.

Potential applications of this technology:

  • Wireless communication systems and networks
  • Mobile devices and user equipment
  • Base stations and antennas

Problems solved by this technology:

  • Efficient and accurate reporting of channel state information in wireless networks
  • Optimization of antenna configurations for secondary cells in a dormancy state

Benefits of this technology:

  • Improved wireless communication performance
  • Enhanced network efficiency and capacity
  • Better utilization of antenna resources
  • More reliable and accurate channel state information reporting


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, signaling indicating a channel state information (CSI) report configuration. The CSI report configuration may indicate a mapping between one or more CSI reference signal (CSI-RS) resources for use in a dormancy state for one or more secondary cells and at least one antenna panel configuration of the base station. Based on the configuration, the UE may receive one or more CSI-RSs on the CSI-RS resources of the one or more dormant secondary cells. In some cases, the UE may receive an antenna adaptation indication based on monitoring a downlink control channel. Additionally or alternatively, the UE may receive scheduling information for a downlink shared channel containing an antenna adaptation indication. The UE may transmit a message reporting CSI feedback to the base station in accordance with the antenna adaptation indication.
