Abstract:
1. A method at a network node in a wireless communications network, the method comprising: partitioning at least a subset of contention based resources for random access attempts into a plurality of partitions, wherein each of said plurality of partitions is associated with at least one precondition governing selection of the partition, the precondition being derived from at least one of: source of causation for the random access attempt, a device state, a device event, a device group, a traffic event, a traffic class, or an application characteristic, and wherein each of said plurality of partitions is further associated with at least one configuration parameter; and communicating configuration parameters for the plurality of partitions and preconditions governing partition usage to at least one of a plurality of user equipments; wherein the partitioning dimensions partitions based on a target probability of collision and access latency.
