Abstract

A method for a wireless terminal of a New Radio (NR) system is provided. The method includes receiving, in a physical downlink control channel (PDCCH) associated with a first serving cell of a plurality of serving cells, downlink control information (DCI). The DCI includes configuration information for one or more physical uplink shared channels (PUSCHs), each PUSCH of the one or more PUSCHs being associated with a corresponding one of one or more of the plurality of serving cells. The DCI also includes trigger information to trigger a generation of a channel state information (CSI) report at the wireless terminal. The method further includes generating, in response to receiving the trigger information, the CSI report, selecting the PUSCH associated with one serving cell of the one or more of the plurality of serving cells, and transmitting the CSI report on the PUSCH associated with the one serving cell.

First claim

1 . A wireless terminal for channel status information (CSI) reporting in a multi-cell scheduling environment, the wireless terminal comprising:
a transmitter; a receiver; one or more non-transitory computer-readable media storing computer-executable instructions; and at least one processor coupled to the one or more non-transitory computer-readable media and configured to execute the computer-executable instructions to cause the wireless terminal to perform operations comprising: receiving, by the receiver, in a physical downlink control channel (PDCCH) associated with a first serving cell of a plurality of serving cells, downlink control information (DCI) including:
configuration information for more than one physical uplink shared channels (PUSCHs), each PUSCH of the more than one PUSCHs being associated with a corresponding one of more than one of the plurality of serving cells, and
trigger information to trigger a CSI report at the wireless terminal;
generating, in response to receiving the trigger information, the CSI report; selecting the PUSCH associated with one serving cell of the more than one of the plurality of serving cells; and transmitting, by the transmitter, the CSI report on the selected PUSCH.

2 . The wireless terminal of claim 1 , wherein:
the one serving cell is a serving cell with the lowest serving cell index of the more than one of the plurality of serving cells.

3 - 15 . (canceled)

16 . A method performed by a wireless terminal for channel status information (CSI) reporting in a multi-cell scheduling environment, the method comprising:
receiving in a physical downlink control channel (PDCCH) associated with a first serving cell of a plurality of serving cells, downlink control information (DCI) including:
configuration information for more than one physical uplink shared channel (PUSCH), each PUSCH of the more than one PUSCH being associated with a corresponding one of more than one of the plurality of serving cells, and
trigger information to trigger a CSI report at the wireless terminal;

generating, in response to receiving the trigger information, the CSI report;
selecting the PUSCH associated with one serving cell of the more than one of the plurality of serving cells; and
transmitting the CSI report on the selected PUSCH.
