Abstract:
1. A mobile radio communication network device comprising: a receiver configured to receive control information from a mobile terminal wherein the receiver is configured to receive the control information in a first mode or in a second mode, wherein in the second mode, less of the control information is received in time from the mobile terminal than in the first mode, a controller configured to control the receiver to receive the control information in the first mode if the mobile terminal is associated with a first mobile terminal mobility class and to control the receiver to receive the control information in the second mode if the mobile terminal is associated with a second mobile terminal mobility class, wherein the second mobile terminal mobility class is a class of terminals with lower mobility than the first mobile terminal mobility class, and to select an extension factor, if the mobile terminal is associated with the second mobility class, based on a number of mobile terminals currently camped on a cell on which the mobile terminal is camped or a semi-static value; and a signaling circuit configured to signal the extension factor to the mobile terminal to adjust a frequency at which the control information is to be transmitted.
