A gateway function converts IP-based content to a VOD asset, and renders the VOD asset to a set top box while mapping digital rights management information for the VOD asset. Conversely, the gateway function may convert a VOD asset to IP-based content that can be played on an IP-based device.
H04N 21/472 - End-user interface for requesting content, additional data or services; End-user interface for interacting with content, e.g. for content reservation or setting reminders, for requesting event notification or for manipulating displayed content
H04N 21/231 - Content storage operation, e.g. caching movies for short term storage, replicating data over plural servers or prioritizing data for deletion
H04N 21/222 - Secondary servers, e.g. proxy server or cable television Head-end
H04N 21/2343 - Processing of video elementary streams, e.g. splicing of video streams or manipulating MPEG-4 scene graphs involving reformatting operations of video signals for distribution or compliance with end-user requests or end-user device requirements
H04L 61/103 - Mapping addresses of different types across network layers, e.g. resolution of network layer into physical layer addresses or address resolution protocol [ARP]
H04L 65/1069 - Session establishment or de-establishment
Wireless communications may use one or more devices for transmission and/or reception that may lead to potentially harmful exposure. One or more safety measures may be used for wireless communication devices, such as maximum power exposure (MPE) reporting and/or related operations. An MPE report may be sent based on MPE detection and one or more messages, such as for cell activation, bandwidth part (BWP) or other wireless resource activation and/or switching, and/or a discontinuous reception (DRX) or other state transition.
H04W 52/36 - Transmission power control [TPC] using constraints in the total amount of available transmission power with a discrete range or set of values, e.g. step size, ramping or offsets
H04W 72/0453 - Resources in frequency domain, e.g. a carrier in FDMA
H04W 72/1263 - Mapping of traffic onto schedule, e.g. scheduled allocation or multiplexing of flows
H04W 74/08 - Non-scheduled access, e.g. random access, ALOHA or CSMA [Carrier Sense Multiple Access]
Systems, apparatuses, and methods are described for generating tokens for user devices to request content items from one or more content delivery networks via networks provided by a network service provider. The tokens may be generated based on rules provided by the network service provider and may indicate whether the content delivery networks have permission to send targeted content items to the user device. Tokens provided to a user device may prevent repeated delivery of the same content item to the user device.
A wireless device may communicate with a base station. Timing advance information may be provided for scheduling sidelink transmission. For example, a wireless device may send a sidelink transmission to another device during a time duration that may be determined based on a timing advance value and/or a timing advance group index.
H04W 72/232 - Control channels or signalling for resource management in the downlink direction of a wireless link, i.e. towards a terminal the control data signalling from the physical layer, e.g. DCI signalling
Multiple transmission reception points (multi-TRP) and single TRP modes may be enabled in a wireless device. By activating one or more transmission configuration indicator (TCI) states, a base station may dynamically switch the wireless device between the Multi-TRP and single TRP modes. A quantity of power headroom values in a power headroom report (PHR), sent to the base station, may be based on the quantity of active TCI states.

CONTROLLING SHARING OF CONTENT TARGETING DATA WITH CONTENT DELIVERY NETWORKS
Systems, apparatuses, and methods are described for controlling sharing of content targeting data (e.g., user-specific data and/or device-specific data) with content- outputting software applications outputting both primary content and secondary content. A user may specify whether the user wants to receive targeted secondary content from the content outputting- software applications. The user may also specify whether the user wants to share content targeting data with the content- outputting software applications. Content targeting data may be shared based on whether the content targeting data is used for selecting targeted secondary content for the user.
Downlink control information (DCI) may be used to schedule a downlink signal for a wireless device that may have a plurality of transmission configuration indicator (TCI) states activated. Each of the TCI states may be associated with a physical cell identifier (PCI) of a cell or a PCI different from the PCI of the cell. The downlink signal may be received using a TCI state determined from the plurality of activated TCI states, based on the quantity of TCI states associated with the PCI of the cell.

H04B 7/0408 - Diversity systems; Multi-antenna systems, i.e. transmission or reception using multiple antennas using two or more spaced independent antennas using two or more beams, i.e. beam diversity
H04W 72/1273 - Mapping of traffic onto schedule, e.g. scheduled allocation or multiplexing of flows of downlink data flows
H04W 72/231 - Control channels or signalling for resource management in the downlink direction of a wireless link, i.e. towards a terminal the control data signalling from the layers above the physical layer, e.g. RRC or MAC-CE signalling
H04W 72/50 - Allocation or scheduling criteria for wireless resources
Encoding and/or decoding a block of a video frame may be based on a previously decoded reference block in the same frame or a different frame. The reference block may be indicated by a block vector (BV). A block vector (BV) may be based on a block vector predictor (BVP) and a block vector difference (BVD). The BVD may be indicated based on a prediction about the magnitude of the BVD, which may improve the compression efficiency of one or more magnitude symbols of a BVD and reduce signaling overhead required for indicating the BVD. The disclosures described herein and used to indicate a BVD also may be used to indicate a motion vector difference (MVD).
