Resource allocation and signaling methods for scheduling in unlicensed spectrum

A network node for a wireless communication network, comprising:

• a processor;
• and memory storing instructions executable by the processor whereby the network node is configured to:
• signal, to a wireless device, an indication of one or more allocated sets of resource blocks that are allocated to the wireless device by an uplink grant for transmission on an uplink carrier in an unlicensed frequency spectrum wherein the one or more allocated sets of resource blocks are a particular combination from among a plurality of combinations of one or more of a plurality of defined sets of resource blocks that correspond to a plurality of interlaces, respectively, that each spread out across an entire bandwidth of the uplink carrier as defined by a default table stored in the wireless device;
• and signal, to the wireless device, via Radio Resource Control signaling, a new table to replace the default table, wherein the new table defines a plurality of new combinations of one or more of the plurality of defined sets of resource blocks that correspond to the plurality of interlaces, respectively, wherein the new table is to be used to interpret one or more subsequent indications of one or more allocated sets of resource blocks for one or more subsequent uplink grants.

A method of operation of a wireless device in a wireless communication network, comprising:

• receiving, from a network node, an indication of one or more allocated sets of resource blocks that are allocated to the wireless device by an uplink grant for transmission on an uplink carrier in an unlicensed frequency spectrum, wherein the one or more allocated sets of resource blocks are a particular combination from among a plurality of combinations of one or more of a plurality of defined sets of resource blocks that correspond to a plurality of interlaces, respectively, that each spread out across an entire bandwidth of the uplink carrier as defined by a default table stored in the wireless device;
• receiving, from the network node, via Radio Resource Control signaling, a new table to replace the default table at the wireless device wherein the new table defines a plurality of new combinations of one or more of the plurality of defined sets of resource blocks that correspond to the plurality of interlaces, respectively, wherein the new table is to be used to interpret one or more subsequent indications of one or more allocated sets of resource blocks for one or more subsequent uplink grants;
• and
• performing uplink transmission on the uplink carrier in accordance with the indication of the one or more allocated sets of resource blocks.
