1. A method comprising:

  • receiving, by a first user device from a base station, control information indicating an assignment of the first user device to a first scheduling request sub-pool of resources of one or more scheduling request sub-pools, and an assignment of the first user device to a first data sub-pool of resources of one or more data sub-pools, wherein the sub-pools assigned to the first user device allow a contention-based grant-free mode transmission from the first user device of both a data and a scheduling request via different resources;

    wherein for at least a plurality of user devices, no two user devices are assigned to both a same data sub-pool and a same scheduling request sub-pool to allow the base station to detect a collision condition for the first user device with respect to both data and a scheduling request, in which a grant-free mode transmission of both a data and a scheduling request at the same time from the first user device collided with uplink transmissions from other user devices.
