Abstract

The invention relates to the technical field of wireless, in particular to a single-point-to-multipoint wireless audio two-way transmission method, system and device. The single-point-to-multipoint wireless audio two-way transmission method comprises the following steps: controlling the access opportunity of the slave equipment by the master equipment and the slave equipment through a random access window period and a control time slot based on the isochronous communication time slot structure, configuring a link resource for the slave equipment, and completing the broadcast transmission of a data packet of the master equipment in a point-to-multipoint audio broadcast time slot, independent sending of slave device data packets is completed in multipoint-to-multipoint audio transmission time slots, efficient management and allocation of link resources are achieved, and the problems that in the prior art, a single-point-to-multipoint wireless audio two-way transmission link is low in efficiency and the like are comprehensively solved.

Description

technical field [0001] The present application relates to the field of wireless technologies, and in particular, to a method, system and device for bidirectional transmission of wireless audio from single point to multipoint. Background technique [0002] At present, wireless audio technology brings people unfettered free calls and music enjoyment, and is widely loved by people. In particular, the Bluetooth Low Energy (BLE: Bluetooth Low Energy) audio (Audio) technology adopts the synchronous isochronous channel (Isochronous Channels) protocol, that is, a single-point-to-single-point communication connected isochronous stream (CIS: Connected Isochronous Stream) link And the Connected Isochronous Group (CIG: Connected Isochronous Group) protocol composed of multiple CIS links realizes single-point to single-point one-way or two-way audio transmission, and broadcast isochronous flow (BIS: Broadcast) of single-point-to-multipoint communication. Isochronous Stream) link and the...
