Abstract: Techniques discussed herein may better ensure efficient fine time tracking during a second cell (SCell) activation procedure by using a tracking reference signal (TRS) that is User Equipment (UE) specific. A primary cell (PCell) may provide a UE with a TRS configuration that includes a UE-specific reference signal (RS) with periodicity or aperiodicity. In response to receiving a SCell activation command from the PCell, the UE may perform cell activation with fine time tracking in accordance with the UE-specific RS. As the delay time for the UE-specific RS may be less than the delay time for a system synchronization block (SSB) from the SCell, use of the UE-specific RS may expedite the cell activation procedure.

Abstract: Dynamically re-locating transcoding processes of live content data is described herein. In an example, a computer system causes a first server to execute a first transcode process on a first portion of live stream content. A first output of executing the first transcode process includes first transcoded content. The computer system determines a transcode capacity of one or more servers. The computer system determines that transcoding the live stream content is to be moved to a second server based at least in part on the transcode capacity and a transcode optimization parameter. The computer system causes the second server to execute a second transcode process on a second portion of the live stream content. The second transcode process is equivalent to the first transcode process. A second output of executing the second transcode process includes second transcoded content.
