Claim of US Patent No. 10,462,813

1. A method in a wireless communication network node for signaling contention-based uplink grants to user equipments, said method comprising:dynamically allocating a continuous range of uplink resource blocks for use in making a plurality of contention-based uplink grants for a given scheduling interval, wherein the range of uplink resource blocks comprises different subsets of uplink resource blocks and wherein each contention-based uplink grant in the plurality of contention-based uplink grants maps to a subset of uplink resource blocks out of the different subsets within the allocated range of uplink resource blocks;
indicating a number of contention-based uplink grants represented by the allocated continuous range of uplink resource blocks; and
transmitting a single contention-based uplink grant message on a physical downlink control channel that indicates the allocated range of uplink resource blocks from which the user equipment selects one of the subsets of uplink resource blocks that corresponds to one of the contention-based uplink grants to send a contention-based uplink transmission within the given scheduling interval.
