Abstract

A wireless device comprises one or more processors and memory storing instructions. When executed by the one or more processors, the instructions cause the wireless device to receive 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 configured with uplink switching based on switched uplink. The instructions cause the wireless device to transmit, based on a first band pair, of the plurality of band pairs, being configured with dual uplink: a first uplink transmission via a first band of the first band pair; and a second uplink transmission via a second band of the first band pair.

Claims (47)

1 . A wireless device comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the wireless device to:

receive a radio resource control (RRC) reconfiguration or setup message comprising configuration parameters, of at least one cell comprising a plurality of uplink carriers, indicating:

uplink switching with three or more uplink bands, wherein each uplink carrier of the plurality of uplink carriers is in a respective uplink band of the three or more uplink bands; and

a plurality of uplink band pairs, from the three or more uplink bands, for the uplink switching, wherein the configuration parameters comprise, for each uplink band pair of the plurality of uplink band pairs, a respective parameter indicating whether a corresponding uplink band pair is configured with:

uplink switching based on dual uplink; or

uplink switching based on switched uplink; and

a second uplink transmission on a second uplink band of the first uplink band pair.

2 . The wireless device of claim 1 , further comprising, based on the first uplink band pair being configured with the uplink switching based on dual uplink, simultaneously transmitting the first uplink transmission and the second uplink transmission.

3 . The wireless device of claim 1 , wherein the first uplink transmission is a first one-port physical uplink shared channel (PUSCH) transmission on a first uplink carrier, of the plurality of uplink carriers, on the first uplink band.

4 . The wireless device of claim 1 , further comprising transmitting capability information of the wireless device indicating a supported band combination comprising the first uplink band and the second uplink band.

5 . The wireless device of claim 1 , wherein the configuration parameters further indicate at least one uplink carrier, of the plurality of uplink carriers, associated with each cell of the at least one cell.
