Abstract: Systems and techniques are described herein for generating and/or processing virtual content in a distributed system (e.g., a distributed extended reality system). For example, a first device (e.g., a client device) of a distributed extended reality system may transmit one or more sets of pose prediction parameters (e.g., prediction coefficients, prediction time associated with raw pose data, and/or the raw pose data) to a second device (e.g., a server device) of the distributed extended reality system. The second device may predict one or more poses of the second device based on the set(s) of pose prediction parameters, and may generate virtual content based on a pose of the predicted pose(s) of the first device. The second may transmit and the first device may receive the virtual content. The first device may then display one or more virtual objects based at least in part on the received virtual content.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a server device may receive, during a first time window, information indicating a plurality of client round-trip times (CRTTs) associated with a client device. The server device may compute a plurality of network round-trip times (NRTTs) based at least in part on the plurality of CRTTs, each NRTT in the plurality of NRTTs corresponding to a respective CRTT in the plurality of CRTTs. The server device may compute one or more NRTT metrics for the first time window using the plurality of NRTTs. The server device may selectively adjust a bitrate used for a transmission to the client device based at least in part on a determination of whether the one or more NRTT metrics satisfy one or more NRTT metric thresholds. Numerous other aspects are described.
