Abstract: A system and method for predicting multi-agent locations is disclosed herein. A computing system retrieves tracking data from a data store. The computing system generates a predictive model using a conditional variational autoencoder. The conditional variational autoencoder learns one or more paths a subset of agents of the plurality of agents are likely to take. The computing system receives tracking data from a tracking system positioned remotely in a venue hosting a candidate sporting event. The computing system identifies one or more candidate agents for which to predict locations. The computing system infers, via the predictive model, one or more locations of the one or more candidate agents. The computing system generates a graphical representation of the one or more locations of the one or more candidate agents.

Abstract: Described are embodiments for transmitting hybrid automatic repeat request (HARQ) feedback information. In one embodiment, a wireless device receives a first downlink control information (DCI) indicating a first slot for transmission of uplink control information (UCI) comprising the HARQ feedback information. The wireless device receives a second DCI scheduling a plurality of physical uplink channels (PUSCHs) in a plurality of consecutive slots comprising the first slot. The wireless device multiplexes the UCI in a first PUSCH, of the plurality of PUSCHs, in the first slot. In response to a failed listen-before-talk (LBT) procedure for the first slot, the wireless device determines a second slot associated with a second PUSCH of the plurality of PUSCHs, and transmits, in response to a successful LBT procedure for the second slot, the UCI via the second PUSCH.

Abstract: A signaling of at least one characteristic for layers of a multi-layered video signal such as, for example, for each layer the indication of dependent layers to which the respective layer directly relates via inter-layer prediction, or the signaling of the afore-mentioned second inter-dependency syntax structure, is described. A maximum syntax element is signaled within the multi-layered video signal to indicate a maximally used value of an extension layer-ID field of the packets of the multi-layered video signal, the scope of the maximum syntax element being, for example, a predetermined portion of the multi-layered video signal extending, for example, across several portions of the multi-layered video signal. Accordingly, it is feasible for devices such as decoders or network elements receiving the multi-layered video signal to gain, for a relatively large predetermined portion of the multi-layered video signal, knowledge about the actually consumed portion of the possible domain of possible values.
