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.

Interference reduction for terminals operating on neighboring bands in wireless communication systems

A method and apparatus for User Equipment (UE) power class adaptation for coverage extension in Long Term Evolution (LTE) includes setting a maximum transmit power to a predefined level that is below a maximum capability of a high power UE (HPUE); responsive to determining, based on detected operating conditions local to the HPUE, that an increase in transmit range is required, raising the maximum transmit power towards or to the maximum capability of the HPUE; and subsequently transmitting at an operating transmit power at or below the maximum transmit power as a function of the detected operating conditions local to the HPUE. The method and apparatus allow the HPUE to infer how to configure its maximum power to mitigate interference to the same class of cells, without assistance from an Evolved Node B (eNB) and within the existing 3GPP LTE framework.

Method and apparatus for power reduction for E-TFC selection

An apparatus and method to reduce uplink compressed mode monitoring in a communication device includes a first step of monitoring a neighboring channel and measuring a channel signal strength. An desense of the monitoring receiver is estimated to determine a threshold, which is compared to the signal strength. If the signal strength is less than the threshold, a new neighboring channel is monitored to see if the signal strength changes. If not, the measured signal is probably interference. In this case, the communication device can request uplink compressed mode to get an accurate signal strength measurement. Only under these condition are uplink compressed mode called for, instead of full time compressed mode, thereby maintaining data capacity.
