Patent number: 11895542Abstract: A technique of performing a HO includes the source BS sending a HO resume message to the UE at the conclusion of a RACH access procedure that occurs in response to a HO command while a second TRX of the UE continues to exchange data packets with the source BS as if no HO command were issued. By continuing to exchange data with the source BS as if there were no HO command until the HO resume message reintroduces a RACH-less HO procedure, the interruption may be reduced to about 4 msec. At any point in time the UE handles only one protocol stack and only one security, which avoids the complexity of the advanced prior art methods.Type: GrantFiled: October 10, 2019Date of Patent: February 6, 2024Assignee: Nokia Technologies OyInventors: Ingo Viering, Jedrzej Stanczak, Ahmad Awada, Tero Henttonen

Patent number: 11864242Abstract: An example embodiment relates to Random Access Channel, RACH, procedure, for example in the New Radio, NR. Random access procedures may be of two types, contention based CBRA and contention free, CFRA. A client device may only perform CBRA fallback when none of the reference signal received strengths, RSRPs, of the synchronization signal blocks, SSBs, which is associated with the CFRA resources is above a predefined threshold, T1. All SSBs and CSI-RS with associated CFRA resources may be below the threshold. Then, the client device may select an SSB or CSI-RS according to a predefined rule and perform CFRA when CFRA resources are associated. Devices, methods and computer programs are disclosed accordingly.Type: GrantFiled: August 14, 2019Date of Patent: January 2, 2024Assignee: Nokia Technologies OyInventors: Ingo Viering, Ahmad Awada, Jedrzej Stanczak, Samuli Heikki Turtinen

Patent number: 11849358Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for a handover of a coordinated multi-point connection. For example, certain embodiment may transfer a first coordinated multi-point connection (e.g., a further enhanced multiple input multiple output (FeMIMO) connection) to a second coordinated multi-point connection where the network may instruct the UE to not perform at least one random access procedure. The first coordinated multi-point connection may be controlled by a first cell (the serving cell) where the UE is ready to receive from and transmit to a first set of cells that comprises the serving cell and one or more non-serving cells. After handover, the second coordinated multi-point connection may be controlled by a previous non-serving cell, and the UE may be ready to receive from and transmit to a second set of cells that comprises the previous non-serving cell.Type: GrantFiled: December 11, 2020Date of Patent: December 19, 2023Assignee: NOKIA TECHNOLOGIES OYInventors: Ingo Viering, Panagiotis Spapis, Alperen Gündogan, Ahmad Awada, Jedrzej Stanczak, Timo Koskela
