1. A method for wireless communications, comprising:
gaining access to a shared channel bandwidth for an occupancy time based at least in part on a channel access procedure, wherein the channel access procedure succeeds in a first slot of the occupancy time;
identifying a second set of resources for transmission of a sharing indicator comprising sharing information for the occupancy time;
transmitting, based at least in part on the gaining access to the shared channel bandwidth and on a sub-channel of the shared channel bandwidth, an occupancy signal via a first set of resources that are included in the first slot of the occupancy time and are prior to the second set of resources for transmission of the sharing indicator in time, wherein the first set of resources and the second set of resources are contiguous in the first slot, and wherein the occupancy signal comprises a repetition of at least a portion of the sharing information included in the sharing indicator;
transmitting, on the sub-channel of the shared channel bandwidth and via the second set of resources after the first set of resources, a sidelink control message comprising the sharing indicator, the sharing information included in the sharing indicator indicating time-division multiplexing (TDM) sharing for a portion of the occupancy time, frequency-division multiplexing (FDM) sharing for the portion of the occupancy time, or a combination thereof; and
communicating during the occupancy time based at least in part on the sharing indicator.
