Title:
METHODS AND DEVICES FOR DETERMINING SPATIAL RELATION, USER EQUIPMENT AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/013013
Kind Code:
A1
Abstract:
The embodiments of the present application provide methods and devices for determining a spatial relation, user equipment (UE) and network device. The method includes: receiving, by UE, first configuration information from a network device, the first configuration information being used to determine N transmission configuration indicator (TCI) state configurations, N being a positive integer; wherein each of the N TCI state configuration is used to determine a reference signal, the reference signal is used to determine a quasi co-location (QCL) type D parameter, the QCL type D parameter is used by the UE to receive physical downlink shared channel (PDSCH); the reference signal is further used to determine a spatial relation information, the spatial relation information is used by the UE to transmit physical uplink shared channel (PUSCH).
