1. A method for wireless communications at a user equipment (UE), comprising:
transmitting an indication of a UE capability to support an extended cyclic prefix;
determining to transmit an uplink message on resources of an uplink channel;
performing a listen-before-talk procedure based at least in part on the determining to transmit the uplink message;
determining a duration of the extended cyclic prefix associated with the resources of the uplink channel;
identifying uplink control information to transmit on the uplink channel based at least in part on an event trigger;
multiplexing the uplink control information and at least one symbol of the uplink message on the uplink channel based at least in part on a timeline that comprises a minimum number of symbols required by the UE between when the event trigger occurs and a start of the uplink channel, the extended cyclic prefix, a timing advance, or a combination thereof; and
transmitting, on the resources of the uplink channel, the extended cyclic prefix according to the determined duration followed by a first symbol of one or more symbols of the uplink message, the extended cyclic prefix based at least in part on the first symbol.
