Control signaling for uplink multiple input multiple output, channel state information reference signal configuration and sounding reference signal configuration

Abstract:

Systems, apparatuses, methods, and computer-readable media are provided for time domain resource allocations in wireless communications systems. Disclosed embodiments include time-domain symbol determination and/or indication using a combination of higher layer and downlink control information signaling for physical downlink shared channel and physical uplink shared channel; time domain resource allocations for mini-slot operations; rules for postponing and dropping for multiple mini-slot transmission; and collision handling of sounding reference signals with semi-statically or semi-persistently configured uplink transmissions. Other embodiments may be described and/or claimed.
