Patent number: 12089100Abstract: Aspects relate to techniques for expediting New Radio (NR) cell addition in non-standalone (NSA) mode. The UE may receive a conditional handover (CHO) command from a first anchor cell operating a first frequency range (e.g., a Long Term Evolution (LTE) frequency range) that enables the UE to subsequently select a different anchor cell to which to perform a handover. The UE may then receive a deconfiguration from the first anchor cell of a measurement object for secondary cell addition in a second frequency range (e.g., a NR frequency range). Based on the CHO command and the deconfiguration of the measurement object, the UE may then perform a handover to a second anchor cell in the first frequency range to facilitate addition of at least one secondary cell in the second frequency range.Type: GrantFiled: October 20, 2021Date of Patent: September 10, 2024Assignee: QUALCOMM IncorporatedInventors: Rishika Tindola, Uttam Vyas, Muralidharan Murugan

Publication number: 20240080738Abstract: Techniques for recovering quickly from a radio link failure (RLF) by identifying potentially strong candidate cells, while avoiding the conventional delays from relying only on initial ACQ DB scans followed by band-scanning, are disclosed. In one aspect, a wireless apparatus such as a user equipment (UE) may identify a radio link failure (RLF) of an existing wireless connection.
