DOWNLINK CONTROL CHANNEL SIGNALING FOR AN APERIODIC CHANNEL STATE INFORMATION TRIGGER

Abstract:

Embodiments described herein relate to downlink (DL) control channel signaling for an aperiodic channel state information (A-CSI) trigger. In one example, a user equipment (UE) communicates with a network to receive first configuration signaling to identify a first downlink control information (DCI) in a physical downlink control channel (PDCCH). The UE also receives, from the network, the first DCI. The first DCI is appended with cyclic redundancy check (CRC) bits that are scrambled by a common radio network temporary identifier (RNTI) and is to indicate an aperiodic channel state information (A-CSI) trigger. Next, the UE receives, from the network, channel state information (CSI) reference signals in one or more occasions that follow an occasion in which the first DCI is received and generates and transmits a CSI report in a physical uplink control channel (PUCCH) based on the CSI reference signals.
