Title:
MULTI-TRANSMISSION MECHANISM INDICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/088267
Kind Code:
A1
Abstract:
The present application discloses a multi-transmission mechanism indication method and device. Said method comprises the following steps: high-layer signaling containing first indication information, the first indication information identifying a type of TDM transmission mechanism; the high-layer signaling containing second indication information, the second indication information identifying a type of FDM transmission mechanism; and downlink control signaling containing dynamic indication information, the dynamic indication information being used for distinguishing TDM, FDM, and SDM transmission mechanisms. The present application further comprises a terminal device, a network device, and a system using said method. The solution of the present application solves the problem of low efficiency during establishment of a transmission mechanism between a network device and a terminal device, satisfying the requirements of dynamically switching transmission mechanisms when a service changes, and reducing signaling overheads to the greatest extent.
