Interference reduction for terminals operating on neighboring bands in wireless communication systems
A wireless communication user terminal includes a controller communicably coupled to a transceiver. The controller is configured to tune the transceiver to transmit on a narrowband uplink control channel within a wideband frequency resource. The uplink control channel includes a pair of uplink control channels separated within the wideband frequency resource wherein the pair of uplink control channels are each located within a corresponding PUCCH resource region. The controller is also configured to change a frequency location of at least one of the uplink control channels, within the corresponding PUCCH resource region, away from an edge of the wideband frequency resource.
1. A wireless communication infrastructure entity in a wireless communication system implementing an uplink control channel using a narrowband frequency resource within a wideband frequency resource, the entity comprising:
a wireless transceiver;
a controller communicably coupled to the transceiver,

the uplink control channel includes at least a pair of uplink control channels separated within the wideband frequency resource, each of the uplink control channels located within an overprovisioned corresponding PUCCH resource region, each of the overprovisioned corresponding PUCCH resource regions specified in terms of resource blocks,
the uplink control channel accommodating simultaneous uplink transmissions by multiple user equipment communicating in the wireless communication system,
wherein allocation of a plurality of control channel resources the begins at a specified resource block according to the uplink control channel offset within at least one of the overprovisioned corresponding PUCCH resource regions, away from an edge of the wideband frequency resource.
2. The entity of claim 1 , the controller configured to cause the transceiver to signal the uplink control channel offset for at least one of the uplink control channels relative to a reference location.
3. The entity of claim 1 , the uplink control channel is a PUCCH located within the overprovisioned PUCCH resource regions.
4. The entity of claim 1 , the controller configured to cause the transceiver to signal, to user equipment that communicates with the wireless communication infrastructure entity, a transmit power limitation for at least one of the uplink control channels conditioned on a narrowband frequency resource allocated for at least one of the uplink control channels.
5. The entity of claim 4 , the controller configured to cause the transceiver to signal the transmit power limitation by enabling or disabling the transmit power limitation using a bit field in a system information block message.
6. A wireless communication user terminal for communicating in a wireless communication system, the terminal comprising:
