Abstract

A method for operating a wireless communication device in a cellular network comprises the steps of: determining power consumption criteria for at least one first time period containing at least one data transmission, carrying out a data transmission session, in case that after said data transmission session the wireless communication device has changed from a first base node to a second base node of the cellular network: determining power consumption criteria for at least one second time period containing at least one data transmission on a second base node, comparing power consumption criteria of the first time period with power consumption criteria of the second time period, carrying out a cell reselection to the first base node, in case at the first time period the determined power consumption criteria indicate a lower power consumption than at the second time period.

Dependent claims

Method for operating a wireless communication device in a cellular network by operating with a first base node of the cellular network, the method comprises the steps for the wireless communication device of:

operating the wireless communication device in enhanced coverage mode;
determining power consumption criteria, based on at least coverage enhancement repetitions, associated with at least one first time period containing at least one data transmission,
after carrying out a data transmission session, switching the wireless communication device from operating with the first base node to operating with a second base node of the cellular network;
determining power consumption criteria, based on at least coverage enhancement repetitions, associated with at least one second time period containing at least one data transmission on the second base node, wherein said second time period occurs after said first time period and is equal in length to the first time period;
comparing the power consumption criteria, based on the at least coverage enhancement repetitions, associated with the first time period, with the power consumption criteria, based on the at least coverage enhancement repetitions, associated with the second time period;
upon determining, based on said comparison, that the power consumption criteria, associated with the first time period, indicates a lower power consumption than that associated with the second time period, carrying out a cell reselection to the first base node.
