Detailed Description The section headings are used in this document only to promote readability and do not limit the scope of the embodiments and techniques disclosed in each section to only that section. Furthermore, for ease of understanding, some embodiments are described with reference to the third generation partnership project (Third Generation Partnership Project,3 GPP) New Radio (NR) standard ("5G"), and the described techniques may be implemented in different wireless systems implementing protocols other than the 5G protocol. The term augmented Reality (eXtended Reality, XR) denotes augmented Reality (Augmented Reality, AR), mixed Reality (MR), and/or Virtual Reality (VR). XR technology combines virtual information generated by real world and digital devices. XR enables user-perceived immersive experience in a mixed reality virtual environment. In order to support high quality XR services, the network needs to provide high data rates and low latency. For example, for downstream XR traffic (e.g., from a base station to a user device), a single stream may include video frames, each having a left eye frame and a right eye frame, sharing the same buffer. Different types of multi-stream (stream) traffic (also referred to as multi-stream (flow)) may be used, such as video stream (stream/flow) and audio stream (stream/flow), field of view (FOV) stream (stream/flow), and omni-directional stream (stream/flow). Packet success rates for XR traffic typically require up to 99% or more. The present application discloses various techniques that may be applied to wireless communication systems to increase bandwidth capacity and reduce latency. In particular, in view of consistency and periodicity in XR traffic (e.g., multiple slots of an XR frame need to be scheduled for packet transmission to achieve data rate and capacity requirements), at the physical layer, a single down
