context: To verify intra-frequency DAPS handover requirements - The UE capable of intra-frequency asynchronous DAPS handover on any band needs to be tested only in asynchronous scenario. - The UE not capable of intra-frequency asynchronous DAPS handover on any band but capable of synchronous DAPS handover on some band needs to be tested only in synchronous scenario. To verify intra-band inter-frequency DAPS handover requirements - The UE capable of intra-band inter-frequency asynchronous DAPS handover on any band needs to be tested only in asynchronous scenario. - The UE not capable of intra-band inter-frequency asynchronous DAPS handover on any band but capable of intra-band inter-frequency synchronous DAPS handover on some band needs to be tested only in synchronous scenario. To verify inter-band inter-frequency DAPS handover requirements - The UE capable of inter-band inter-frequency asynchronous DAPS handover on any band combination needs to be tested only in asynchronous scenario. - The UE
description: Dual Active Protocol Stack (DAPS) is a technology that enables the simultaneous use of two protocol stacks, typically for different radio access technologies (RATs), within a single device or network component.
explanation: The context provided from 3GPP TS 38.133 highlights DAPS in relation to handover scenarios and testing requirements across various bands and frequencies, indicating its role as a technology standard governing telecommunications operations.
