Title:
BEAM INDICATION METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/213921
Kind Code:
A1
Abstract:
A beam indication method, a device, and a system, the method comprising: a terminal device receives activation signaling, the activation signaling activating at least one transmission; the terminal device sends or receives the at least one transmission on the basis of the understanding that: before receiving deactivation signaling or subsequent activation signaling, all transmissions activated by the activation signaling use the same spatial filter or transmission assumptions, or use respective spatial filters or transmission assumptions determined by means of dynamic interpretation of the activation signaling. Thus, for semi-persistently scheduled or periodically scheduled transmissions, the same spatial filter or transmission assumptions, or respective spatial filters or transmission assumptions determined by means of dynamic interpretation of activation signaling are used between activation signaling and deactivation signaling or subsequent activation signaling to perform sending or receiving, solving the problem of beam indication fuzziness in the described interval.
