Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station (BS), a UE capability indicator of a capability of the UE. The BS may select an uplink switch mode. The UE may receive, from the BS, signaling identifying the uplink switch mode, of a plurality of uplink switch modes, for switching one or more transmit chains of the UE between a first uplink duplex configuration and a second uplink duplex configuration. The UE may switch at least one uplink duplex configuration of at least one transmit chain of the UE based at least in part on the uplink switch mode. Numerous other aspects are provided.

A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- transmit, to a network node, a UE capability indicator of a capability of the UE;
- receive, from the network node, signaling identifying an uplink switch mode, of a plurality of uplink switch modes, for switching one or more transmit chains of the UE between a first duplex configuration and a second duplex configuration,
- wherein the first duplex configuration is associated with the UE transmitting on a first uplink using a first carrier and a first transmit chain and transmitting on a second uplink using a second carrier and a second transmit chain, and
- wherein the second duplex configuration is associated with the UE transmitting on a third uplink using the second carrier and both the first transmit chain and the second transmit chain;
- and
- switch amongst the first duplex configuration and the second duplex configuration based at least in part on the uplink switch mode.
A network node for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- receive, from a user equipment (UE), a UE capability indicator of a capability of the UE;
- select, based at least in part on the UE capability indicator, an uplink switch mode, of a plurality of uplink switch modes, for switching one or more transmit chains of the UE between a first duplex configuration and a second duplex configuration,
- wherein the first duplex configuration is associated with the UE transmitting on a first uplink using a first carrier and a first transmit chain and transmitting on a second uplink using a second carrier and a second transmit chain, and
- wherein the second duplex configuration is associated with the UE transmitting on a third uplink using the second carrier and both the first transmit chain and the second transmit chain;
- and
- transmit, to the UE, signaling identifying the uplink switch mode to enable the UE to switch amongst the first duplex configuration and the second duplex configuration.
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting, to a network node, a UE capability indicator of a capability of the UE;
- receiving, from the network node, signaling identifying an uplink switch mode, of a plurality of uplink switch modes, for switching one or more transmit chains of the UE between a first duplex configuration and a second duplex configuration,
- wherein the first duplex configuration is associated with the UE transmitting on a first uplink using a first carrier and a first transmit chain and transmitting on a second uplink using a second carrier and a second transmit chain, and
- wherein the second duplex configuration is associated with the UE transmitting on a third uplink using the second carrier and both the first transmit chain and the second transmit chain;
- and
- switching amongst the first duplex configuration and the second duplex configuration based at least in part on the uplink switch mode.
A method of wireless communication performed by a network node, comprising:
- receiving, from a user equipment (UE), a UE capability indicator of a capability of the UE;
- selecting, based at least in part on the UE capability indicator, an uplink switch mode, of a plurality of uplink switch modes, for switching one or more transmit chains of the UE between a first duplex configuration and a second duplex configuration,
- wherein the first duplex configuration is associated with the UE transmitting on a first uplink using a first carrier and a first transmit chain and transmitting on a second uplink using a second carrier and a second transmit chain, and
- wherein the second duplex configuration is associated with the UE transmitting on a third uplink using the second carrier and both the first transmit chain and the second transmit chain;
- and
- transmitting, to the UE, signaling identifying the uplink switch mode to enable the UE to switch amongst the first duplex configuration and the second duplex configuration.
