Abstract:
Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for maintaining simultaneous connection with a network in dual-active protocol stack (DAPS) handover (HO), such as, for example, in packet data convergence protocol (PDCP) duplication applications that require a user equipment (UE) to maintain up to four simultaneous connections with the network, such as in an multi-radio access transfer (RAT) dual connectivity (MR-DC) to MR-DC HO. In some embodiments, the UE is configured during various phases of a DAPS HO. In some other embodiments, the UE may be configured for multi-TRP operations.
