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

This abstract first appeared for US patent application 17382212 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.
  • Each EBCS DL packet carries signaling indicating 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 of this technology:

  • Enhanced broadcast services (EBCS) in wireless communication networks.
  • Delivering specific data to wireless stations that support EBCS while maintaining compatibility with non-EBCS stations.

Problems solved by this technology:

  • Ensuring reliable delivery of EBCS downlink packets to EBCS supporting wireless stations.
  • Maintaining interoperability with wireless stations that do not support EBCS.

Benefits of this technology:

  • Improved delivery of enhanced broadcast services to compatible wireless stations.
  • Efficient utilization of network resources by targeting EBCS data only to supporting stations.
  • Seamless coexistence of EBCS and non-EBCS stations in the same network.


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.
