TRP SUBSET SELECTION AND REPORTING: abstract simplified (18295219)

• This abstract for appeared for patent application number 18295219 Titled 'TRP SUBSET SELECTION AND REPORTING'

Simplified Explanation

This abstract describes apparatuses and methods for selecting and reporting a subset of transmit-receive points (TRP) in a wireless communication system. The method involves a user equipment (UE) receiving information about a channel state information (CSI) report, which includes details about multiple groups of CSI reference signal (CSI-RS) ports and a list of states. Each state corresponds to a subset of the CSI-RS port groups. The UE then selects at least one state from the list, measures the CSI-RS ports in the selected state, and determines CSI based on the measurements. Finally, the UE transmits the CSI report, including the determined CSI.

Original Abstract Submitted

Apparatuses and methods for transmit-receive point (TRP) subset selection and reporting. A method performed by a user equipment (UE) is provided. The method includes receiving information about a channel state information (CSI) report. The information indicates N>1 groups of CSI reference signal (CSI-RS) ports and a list of S states. Each of the S states correspond to a subset of the N groups of CSI-RS ports. The method further includes, based on the information, selecting at least one state from the list of S states, measuring at least one of the N groups of CSI-RS ports, and determining CSI based on the measurement. The method further includes transmitting the CSI report including the determined CSI.
