Title:
AIR INTERFACE DELAY DETERMINATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/042380
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provides an air interface delay determination method and apparatus. The method comprises: an access network device obtains an air interface delay of a downlink data packet, and schedules the downlink data packet according to the air interface delay of the downlink data packet, the air interface delay of the downlink data packet being obtained by calculation according to a loopback delay, and the loopback delay referring to the delay that needs to be met from a terminal sending an uplink data packet to receiving a downlink data packet corresponding to the uplink data packet. In the method, the access network device can schedule the downlink data packet according to the air interface delay of the downlink data packet, thereby accurately controlling the delay of uplink and downlink data transmission, and providing a guarantee for the uplink and downlink data transmission meeting the loopback delay.
