The invention relates to a wireless device capable of receiving at least one message from a base station. The message may include configuration parameters. Configuration settings can indicate periodic resources for a configured authorization. The configured permission can be configured in an uplink bandwidth portion. Configuration settings can specify a timer value for a bandwidth part inactivity timer. The bandwidth portion inactivity timer can be started in response to the activation of a downlink bandwidth portion. At least one data packet may be transmitted through a first transmission interval of a first resource of the periodic resources of the uplink bandwidth portion. The bandwidth portion inactivity timer can be restarted at a certain time based on the first transmission interval. In response to an expiry of the bandwidth portion inactivity timer, the wireless device may switch from the downlink bandwidth portion to a default bandwidth portion as an active bandwidth portion. |
