Patent number: 10681590Abstract: The embodiments of the invention, as described below, introduce a new full configuration flag to distinguish full configurations of low complexity category UEs from other categories. The new full configuration flag will also be referred to herein as an “enhanced” full configuration flag. A network node, such as a source eNB, can see the enhanced full configuration flag from the RRC configuration message that is prepared by another network node, for example a target eNB. If the target eNB sends a RRC configuration that contains a legacy version of the full configuration flag for a low complexity category UE, the source eNB knows that the target eNB does not comprehend Rel-12 and the low complexity category. Accordingly the source eNB can refrain from performing the handover. In addition, the UE can infer from the flag version if the target eNB has comprehended the UE category and accordingly it knows whether the configuration is valid or not.Type: GrantFiled: April 9, 2015Date of Patent: June 9, 2020Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventor: Kai-Erik Sunell

Publication number: 20200120560Abstract: Methods for handover of a wireless device from a source cell served by a source base station to a target cell served by a target base station. An example method, implemented in the source base station, comprises obtaining a command for transmission to the wireless device, the command comprising configuration information that comprises an indication of at least one uplink grant time for uplink resources in the target cell, specified in terms of at least one system frame number (SFN) value. The method further comprises transmitting the command to the wireless device. The configuration information in the command comprises information sufficient to enable the wireless device to determine a time or times for accessing uplink resources in the target cell without obtaining SFN values from the target cell. The command may be a handover command for a random access channel-less (RACH-less) handover of the wireless device to the target cell.Type: ApplicationFiled: October 9, 2017Publication date: April 16, 2020Inventors: Kai-Erik Sunell, Jens Bergqvist, Henrik Enbuske
