- the handover between two sets requires a predetermined handover delay, and then until a new handover signaling is received or a predetermined time arrives, UB-SRS set2 is used as the active set, that is, PUSCH
- the transmit spatial filtering parameters in can only come from UB-SRS set2. It can be similarly used in the handover of the other sets mentioned above. That is, for example, Q objects are configured in high-level signaling, and the indication information of Q objects is notified in the physical layer dynamic control signaling. When the indicated Q objects are different from the current object, the object switching process is started, and the current object is activated to new. For the object, a new object notified in the physical layer dynamic control signaling is used on the time domain resource after the handover. It is also possible to switch from one object to another and to switch from one time-domain resource collection to another time-domain resource collection by means of a scheduled time.
