Method and apparatus for adaptive bandwidth usage in a wireless communication network

A method of a wireless communication device configured for operation in a wireless communication network, comprising, based on controlling a dynamically configurable bandwidth of receiver circuitry of the wireless communication device:

• monitoring a first downlink bandwidth for downlink transmissions by a serving node of the wireless communication device in the wireless communication network, the first downlink bandwidth being only a portion of an overall system bandwidth of the serving node;
• receiving control signaling in the first downlink bandwidth, indicating a change from the first downlink bandwidth to a second downlink bandwidth;
• in response to the indicated change, monitoring the second downlink bandwidth for downlink transmissions by the serving node, the second downlink bandwidth being only a portion of the overall system bandwidth;
• and
• in response to expiration of a reception inactivity timer while monitoring the second downlink bandwidth, changing from the second downlink bandwidth to the first downlink bandwidth or a third downlink bandwidth, the third downlink bandwidth being only a portion of the overall system bandwidth.

A non-transitory computer readable medium storing a computer program comprising instructions that, when executed on a processor of a wireless communication device, cause the wireless communication device to control a dynamically configurable bandwidth of receiver circuitry of the wireless communication device, to:

• monitor a first downlink bandwidth for downlink transmissions by serving node of the wireless communication network in the wireless communication network, the first downlink bandwidth being only a portion of an overall system bandwidth of the serving node;
• receive control signaling in the first downlink bandwidth, indicating a change from the first downlink bandwidth to a second downlink bandwidth;
• in response to the indicated change, monitor the second downlink bandwidth for downlink transmissions by the serving node, the second downlink bandwidth being only a portion of the overall system bandwidth;
• and
• in response to expiration of a reception inactivity timer while monitoring the second downlink bandwidth, change from the second downlink bandwidth to the first downlink bandwidth or a third downlink bandwidth, the third downlink bandwidth being only a portion of the overall system bandwidth.
