Patent number: 10425212Abstract: Format of a downlink control channel for a user equipment UE is changed in conjunction with switching the UE between being enabled for cross carrier scheduling and being disabled for cross carrier scheduling. The changed format is used on at least one serving cell of the UE's configured set of component carriers CCs. In one embodiment the changed format comprises an explicit carrier indicator field CIF for the case in which the switching is from disabled to enabled; and the changed format has no explicit CIF when the switching is from enabled to disabled. In another embodiment switching from disabled to enabled comprises the UE's configured set of CCs being changed from one to multiple cells; and switching from enabled to disabled comprises the UE's configured set of CCs being changed from multiple cells to one cell. In one embodiment the changed format is implicit.Type: GrantFiled: December 2, 2014Date of Patent: September 24, 2019Assignee: CELLULAR COMMUNICATIONS EQUIPMENT LLCInventors: Woonhee Hwang, Jarkko T.

Patent number: 9414223Abstract: A method for security for inter-RAT carrier aggregation is disclosed. The method includes encrypting a message using an encryption technique for a first RAT. The method also includes sending, to a UE, at least a portion of the encrypted message using a different, second RAT. Sending using the second RAT does not further encrypt the at least a portion of the encrypted message. The method further includes receiving the at least a portion of the message encrypted using the first RAT protocol. Receiving uses the second, different RAT. The method also includes decrypting the at least a portion of the message using the first RAT protocol. Apparatus and computer readable media are also described.Type: GrantFiled: February 17, 2012Date of Patent: August 9, 2016Assignee: Nokia Technologies OyInventors: Philip Ginzboorg, Esa M.
