In a shared-medium network, a hopping pattern provisioned by a transmitting device designates a plurality of frequency channels and a corresponding plurality of times. The transmitting device splits data into multiple radio-burst payloads, and transmits the data on the frequency channels according to the hopping pattern, wherein an intended receiving device has no prior knowledge of the hopping pattern. The resulting unpredictable transmission property provides robust, efficient, and interference-resistant reception in the presence of networks operating with different standards and disparate organization. Additional aspects allow reception of ad-hoc transmissions in dense environments without scheduling, CSMA/CA protocols, or scheduling feedback paths; and allows macro-diverse reception of transmissions at networks of connected receivers, thereby providing additional efficiency and security improvements that exploit route diversity of the network.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a feedback resource associated with a sidelink feedback channel, wherein the feedback resource is associated with an eight-level code division multiplexing (CDM) scheme. The UE may transmit a feedback communication associated with a sidelink data communication using the feedback resource, wherein transmitting the feedback communication is based at least in part on using the eight-level CDM scheme to generate the feedback communication. Numerous other aspects are described.
