Claim 17:
18. A cellular base station (BS), comprising:
at least one antenna;
at least one radio coupled to the at least one antenna; and
at least one processor coupled to the at least one radio;
wherein the cellular base station is configured to support a target cell operating in frequency range 2 (FR2) above 24 GHz, and wherein the at least one processor is configured to cause the BS to:
receive, from a wireless device, one or more indications of a dual active protocol stack (DAPS) handover capability of the wireless device corresponding to FR2 wherein the one or more indications further indicate a capability of the wireless device to support DAPS handover in FR2 with common beam management (CBM) or independent beam management (IBM);
transmit, to the wireless device, a command to perform a DAPS handover from a source cell operating in the FR to the target cell;
receive, from the wireless device, signaling corresponding to a physical random access channel (PRACH) procedure; and
transmit, upon successful completion of the PRACH procedure, a source cell release command to the wireless device,
wherein the source cell release command is configured to indicate a release of a data connection between the wireless device and the source cell.
