The sensor unit detects removal of an option device, which is configured to be attachable/detachable to/from a body portion of the image forming apparatus, with respect to the body portion.

The judgment unit judges, when the sensor unit detects removal of the option devices, whether at least one of the programs to be stored in the storage unit becomes non-executable due to the removal of the option devices.

Abstract: The invention relates to a method for transmitting power headroom information from a user equipment to the base station. The transmission is made dependent on scheduling type of the uplink resource, for which the power headroom information is to be calculated and over which it is to be transmitted. If the uplink resource is dynamically scheduled, then the extended power headroom report according to Rel. 10 is transmitted; if it is scheduled persistently, e.g. as part of a semi-persistent scheduling configuration, then a basic power headroom report according to Rel. 8/9 is transmitted. The invention circumvents the problem of delaying data in persistently allocated uplink resources when transmitting an extended power headroom report.
