METHODS AND SYSTEMS FOR BEAM RECOVERY AND MANAGEMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240023183 titled 'METHODS AND SYSTEMS FOR BEAM RECOVERY AND MANAGEMENT
Simplified Explanation
The patent application describes a system and methods for managing and recovering from beam failures in multi-carrier communications with beamforming. Here is a simplified explanation of the abstract:
- A wireless transmit/receive unit (WTRU) monitors and detects a beam failure of a beam associated with a secondary cell (Scell). - The WTRU selects a candidate beam for the Scell. - The WTRU transmits a medium access control (MAC) control element (CE) on an uplink resource in a primary cell (SPcell), indicating the Scell beam failure and identifying the selected candidate beam. - The WTRU receives a response on the SPcell indicating an Scell index and a downlink (DL) quasi co-location (QCL) reference associated with the Scell. - The WTRU verifies that the DL QCL reference matches with the candidate beam. - The WTRU performs random access on the Scell using the selected QCL reference and the selected candidate beam.
Potential applications of this technology:
- Wireless communication systems with beamforming capabilities. - Multi-carrier communication networks. - Cellular networks with secondary cells.
Problems solved by this technology:
- Beam failures in multi-carrier communications can lead to loss of signal and degraded performance. This technology provides a method for detecting and recovering from beam failures. - The system allows for the selection of a candidate beam and verification of the DL QCL reference, ensuring reliable communication in the Scell.
Benefits of this technology:
- Improved reliability and performance in multi-carrier communications with beamforming. - Efficient recovery from beam failures, minimizing signal loss and downtime. - Enhanced management of secondary cells in cellular networks.
Original Abstract Submitted
a system and methods for beam failure recovery and management for multi-carrier communications with beamforming are disclosed herein. a wireless transmit/receive unit (wtru) may monitor for and detect a beam failure of a beam associated with a secondary cell (scell). the wtru may select an scell candidate beam. the wtru may transmit using a selected uplink (ul) resource in a primary cell (spcell) a medium access control (mac) control element (ce) including an indication of scell beam failure and identifying the selected candidate beam. the wtru may receive an scell beam failure indication response on the spcell indicating an scell index and a downlink (dl) quasi co-location (qcl) reference associated with the scell. the wtru may verify that the dl qcl reference matches with the candidate beam. the wtru may perform random access on the scell using the selected qcl reference and the selected candidate beam.
