ENHANCED BROADCAST SERVICES (EBCS) DOWNLINK BROADCASTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17382218 titled 'ENHANCED BROADCAST SERVICES (EBCS) DOWNLINK BROADCASTS

Simplified Explanation

This patent application describes methods, devices, and systems for delivering enhanced broadcast services (EBCS) downlink packets to wireless stations (STAs) that support EBCS while maintaining compatibility with STAs that do not support EBCS.

  • The wireless communication device broadcasts EBCS DL packets containing data related to an EBCS service.
  • A trigger frame is transmitted to request information about missed EBCS DL packets from EBCS STAs in the area.
  • Signaling within each EBCS DL packet indicates that the broadcast data is intended only for EBCS STAs.
  • An EBCS traffic advertisement is broadcasted to indicate the timing of the EBCS DL packets.

Potential Applications

  • Enhanced broadcast services in wireless communication networks
  • Reliable delivery of data to wireless stations supporting EBCS

Problems Solved

  • Ensuring reliable delivery of EBCS DL packets to EBCS STAs
  • Maintaining interoperability with STAs that do not support EBCS

Benefits

  • Improved delivery of enhanced broadcast services
  • Compatibility with both EBCS and non-EBCS supporting STAs


Original Abstract Submitted

This disclosure provides methods, devices and systems for reliable delivery of enhanced broadcast services (EBCS) downlink (DL) packets to wireless stations (STAs) that support EBCS (also referred to as “EBCS STAs”) and maintaining interoperability with STAs that do not support EBCS. A wireless communication device may broadcast one or more EBCS DL packets carrying data associated with an EBCS service. In some aspects, the wireless communication device may subsequently transmit a trigger frame soliciting information indicating which, if any, of the EBCS DL packets were missed by EBCS STAs in the vicinity. In some other aspects, each EBCS DL packet may carry signaling indicating that the broadcast data is intended only for EBCS STAs. Still further, in some aspects, the wireless communication device may broadcast an EBCS traffic advertisement indicating a timing of the one or more EBCS DL packets.
