Document Type and Number:

WIPO Patent Application WO/2023/129674

Kind Code:

A3

Abstract:

A wireless device receives one or more radio resource control (RRC) messages indicating: a plurality of band pairs for uplink switching and whether each band pair, of the plurality of band pairs, is configured with uplink switching based on dual uplink or switched uplink. The wireless device may also transmit a first uplink transmission via the first band of the first band pair and a second uplink transmission via a second band of the first band pair. The transmission may be based on a first band pair being configured with dual uplink.
