Abstract: A method includes receiving, by a user equipment (UE), a first signal from a first apparatus, the first signal comprising a first data for presentation by a second apparatus and a second data for presentation by a third apparatus, the first data and the second data being synchronized with each other in time. The UE extracts the first and second data from the first signal, and determines a timing for transmitting a second signal that comprises the first data to the second apparatus and for transmitting a third signal that comprises the second data to the third apparatus, the timing configured to approximately synchronize in time presentation of the first data and second data by the respective second and third apparatuses. The UE transmits the second signal to the second apparatus based on the timing, and transmits the third signal to the third apparatus based on the timing.

Abstract: Methods, apparatuses, and computer program products are provided for facilitating seamless split rendering session relocation when a quality of a rendered viewport for extended Reality (XR) media content from a current split rendering server becomes degraded. A new split rendering server can be provisioned in parallel with the current split rendering server and a rendered viewport negotiation or comparison can be carried out. A split rendering client can provide pose information and sensor data for viewport and/or field of view prediction to both the current split rendering server and the new split rendering server during a transition period. The current split rendering server can continue during this transition period to provide rendered viewport-specific XR media content to the split rendering client while an application function or session management function determines when the split rendering session should be relocated to the newly provisioned split rendering server.
