Patent ID: 10574321

Abstract:
In one aspect, a base station (e.g., a TRP) transmits an indication of a joint P3 sweep to a wireless device which triggers the wireless device (e.g., a UE) to perform the joint P3 sweep. In another aspect, the wireless device performs the joint P3 sweep by obtaining measurements based on a first set and second set of one or more one-port or two-port channel state information reference signal (CSI-RS) transmissions from the TRP. The wireless device determines the aggregated channel estimation based on the obtained measurements. The wireless device determines at least one or more of a precoding matrix indicator (PMI), a modulation and coding scheme (MCS), and a rank based on the determined aggregated channel estimation and reports the determined at least one or more PMI, MCS, and rank in one channel state information (CSI) report.
