Patent number 372024 has been granted to Telefonaktiebolaget LM Ericsson that is titled UPLINK SYNCHRONIZATION PROCESSING. The primary independent claim of this patent states a method of enabling uplink synchronization of user equipment present in a cell served by a radio base station, wherein it includes transmission of a first timing alignment command to a user equipment by a transmitter that further triggers the timing alignment timer of user equipment with a defined length of an associated time interval. The patent applicant responded to this objection by stating that the present invention provides a portable device (e.g. synchronization device) that include transmitters, timing measurer, timing determiner and transmission scheduler i.e, synchronization device in a whole, that enables uplink synchronization of user equipment present in a cell that is served by a radio base station. This patent falls under the category of Communication. Overall, this patent covers uplink synchronization of user equipment by a radio base station, which is enabled by triggering start of timing alignment, in response to a first TA command.
