The terminal device uses resourced configured for the active uplink (UL) BWP but with the different periodicity. In this way, it allows sounding reference signal (SRS)/channel state information (CSI) reporting without duplicating configurations of BWPs. It can configure a required longer periodicity but reduce the SRS configuration for each UL BWP. | 2021-11-25 |
