Wideband PDCCH for unlicensed band useful for new radio

An apparatus, comprising at least one processor and at least one memory including computer instructions that, when executed by the at least one processor, cause the apparatus to:

• perform at a user equipment first control channel monitoring according to a first control resource set and at least one first search space set configuration, the first control channel monitoring performed on n subbands, n>1, able to be transmitted by a base station in an unlicensed band carrier;
• determine, in response to a detection of a control channel in the monitoring and from the control channel, transmission bandwidth configuration to be used by the base station in the unlicensed band carrier for control channels;
• and
• perform by the user equipment second control channel monitoring according to a second control resource set and at least one second search space set configuration, the second control channel monitoring performed on m subbands, m≤n, in the unlicensed band carrier, the m subbands being a subset of the n of subbands.
