The present disclosure provides a wireless audio data transmission method and related devices. The method comprises: broadcasting, by a transmitting device, a hybrid auxiliary synchronization packet to a plurality of receiving devices. The hybrid auxiliary synchronization packet comprises a first link information and a second link information, the first link information is used by a first receiving device among the plurality of receiving devices to synchronize with the transmitting device and establish a first Broadcast Isochronous Group (BIG) link, and the second link information is used by a second receiving device among the plurality of receiving devices to synchronize with the transmitting device and establish a second BIG link; transmitting a first broadcast data packet based on the first BIG link, and/or transmitting a second broadcast data packet based on the second BIG link. The method enables more flexible applications of multi-channel wireless broadcast audio.

An electronic device and a method for implementation for schedule-based channel bonding for delivery of media content. The system determines a schedule of delivery of a media file to a plurality of receiver devices that are within a coverage area of the broadcast station. The system broadcasts, over a signal, signaling information that includes the schedule to the plurality of receiver devices. The system performs, based on the signaling information, a channel bonding operation to combine a plurality of radio channels into a bonded channel, wherein the plurality of radio channels is associated with one or more radio transmission spectrums. The system transmits the media file to the plurality of receiver devices over the bonded channel, based on the schedule.
