The network may configure a contention-based resource pool for user equipments (UEs) to transmit uplink data with reduced signaling overhead. A UE may select to transmit an uplink message in a configured contention-based resource of the contention-based resource pool without receiving an uplink grant for the contention-based resource. Some uplink traffic types may have stricter delay budgets than other types of uplink traffic. A UE may select an uplink contention-based resource from a contention-based resource pool based on the delay status of an uplink data packet. The UE may determine a probability of accessing the uplink contention-based resource based on the remaining delay budget of the uplink packet. For example, the network may configure a function for the UE to determine the probability of accessing an uplink contention-based resource based on the delay status of a given uplink packet. ## Claims ### Claim 1 A user equipment (UE), comprising: one or more memories storing processor-executable code;
