Patent number: 10575236Abstract: Improved mechanisms for wireless cellular access using coverage extension techniques are described. A UE needing to use coverage extension to request access to a prospective serving cell detects cells (other than the prospective serving cell) on its frequency, and then investigates each such cell (for example, by attempting to read its system information block and, if the system information block can be read, determining if the cell supports access using coverage extension. If detected cells do not support coverage extension, the UE does not use coverage extension techniques to request access, but if all detected cells support coverage extension, the UE requests access using coverage extension techniques.Type: GrantFiled: March 20, 2014Date of Patent: February 25, 2020Assignee: Nokia Solutions and Networks OyInventors: Guillaume Decarreau, Benoist Pierre Sebire, Woonhee Hwang, Rapeepat Ratasuk

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.
