Techniques for adaptive sub-band usage for uplink control channel

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors configured to:
• identify a control channel resource configuration associated with an unlicensed spectrum, wherein the control channel resource configuration includes an indication of whether a resource, to be used for an uplink control channel in the unlicensed spectrum, is a fixed resource, a floating resource, or an adaptive resource,
• wherein the fixed resource is associated with a fixed frequency location,
• wherein the floating resource is associated with a fixed bandwidth and a variable frequency location, and
• wherein the adaptive resource is associated with a variable bandwidth and a variable frequency location;
• identify the resource based at least in part on the control channel resource configuration;
• and
• transmit uplink control information on the identified resource.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
• identify a control channel resource configuration associated with an unlicensed spectrum, wherein the control channel resource configuration includes an indication of whether a resource, to be used for an uplink control channel in the unlicensed spectrum, is a fixed resource, a floating resource, or an adaptive resource,
• wherein the fixed resource is associated with a fixed frequency location,
• wherein the floating resource is associated with a fixed bandwidth and a variable frequency location, and
• wherein the adaptive resource is associated with a variable bandwidth and a variable frequency location;
• identify the resource based at least in part on the control channel resource configuration;
• and
• transmit uplink control information on the identified resource.

An apparatus for wireless communication, comprising:

• means for identifying a control channel resource configuration associated with an unlicensed spectrum, wherein the control channel resource configuration includes an indication of whether a resource, to be used for an uplink control channel in the unlicensed spectrum, is a fixed resource, a floating resource, or an adaptive resource,
• wherein the fixed resource is associated with a fixed frequency location,
• wherein the floating resource is associated with a fixed bandwidth and a variable frequency location, and
• wherein the adaptive resource is associated with a variable bandwidth and a variable frequency location;
• means for identifying the resource based at least in part on the control channel resource configuration;
• and
• means for transmitting uplink control information on the identified resource.
