A wireless device may perform a listen-before transmit (LBT) procedure for an uplink transmission. An LBT failure recovery procedure may be initiated based on a failure of one or more LBT procedures. The LBT failure recovery procedure may be aborted and/or canceled based on one or more conditions, such as receiving configuration (or reconfiguration) parameters, receiving an indication of a bandwidth part switching, deactivating a cell, and/or receiving a request to set (or reset) a communication layer of the wireless device.
Systems, apparatuses, and methods are described for wireless communications. Beam failure recovery (BFR) may be used for recovering a beam pair link between a base station and a wireless device. A wireless device and/or a base station may detect a beam failure and determine a type of BFR procedure, resources for the BFR procedure, and a transmission power for the BFR procedure.

Systems, apparatuses, and methods are described for wireless communications. Random access procedures may include various types of procedures, such as four-step or two-step random access procedures. One or more indicators may be included in one or more messages for a handover to indicate a type of a random access procedure. Additionally or alternatively, one or more indicators for transmission power may be used to determine a random access procedure.
A wireless device receives one or more messages. The one or more messages may comprise a first RNTI for a first SPS and a second for a second SPS. A downlink control information (DCI) corresponding to one of the first RNTI or the second RNTI may be received. The DCI may be validated, at least based on a cyclic shift value associated with the DCI, if the DCI corresponds to the first RNTI. Otherwise, the DCI may be validated without considering the cyclic shift value. One of the first SPS or the second SPS, corresponding to the DCI, may be activated in response to the validating being successful.
Systems for distributed controlled access to data stored across a plurality of sources are disclosed. A plurality of content providers maintain user databases. A first distributed database contains a master identifier for each user of each content provider. Stored in relation to the master identifier are the locations of the user's data in each of the content providers. A second distributed database comprises data identifying for each of the users, entities that are authorized to access the user's data. In response to a request from an entity, the second database is queried and, based upon access rights data, user's whose data the requesting entity may view are determined. The first distributed database is queried to determine for the identified user, the location of user data. The data is retrieved and stored at a location accessible by the entity. The second distributed database is updated to record the data access.

A content adaptation method includes: obtaining a primary metadata profile associated with a particular time point of primary content; obtaining secondary metadata profiles each associated with corresponding secondary content of a plurality of secondary content; identifying one of the plurality of secondary content associated with a secondary metadata profile having a desired similarity value with the primary metadata profile associated with the primary content; and matching the identified secondary content with the particular time point of the primary content.

A computing device may be configured to provide authorization to a first content source to provide first content to a user device. The computing device may receive a request from the first content source to identify a location of second content to be presented to the user device and respond to the request by providing an address to the first content source. At the provided address, a request for the second content from the user device may be received. When responding to the request, the computing device may retrieve information associated with the user (e.g., user preference information) from the user device. Using this information, the computing device may generate at least one parameter for selecting the second contend and send a response to the user device. The response may include an address for the second content and the at least one parameter for selecting the second content.
Aspects of the disclosure relate to routing queries to a network repository and load balancing in a network. For a network repository having a plurality of content storage sites, relative replication latency of data among a pair of content storages sites can be monitored. Data indicative of such replication latency can be distributed among the content storage sites and can be provided, for example, to a network node in a system layer. A traffic and control manager can determine routing pathways for queries based at least in part on the relative replication latency data and performance conditions of network nodes.
The features relate generally to acquiring, formatting, and distributing video content to a variety of devices in multiple geographies. Some features described herein relate to preserving the stereoscopic effect for the formatting and distribution of 3D video content. Additionally, features described herein relate to customized and/or dynamic generation of a 3D stream based on a user device and/or user preferences.
A modem system may include modems that have multiple upstream transmitters for transmitting signals upstream in a communication network. In some embodiments herein, one or more of those upstream transmitters may be retasked to transmit downstream signals for reception at devices within a modem's premises. The downstream signal may be modulated differently from its original modulation as received by the modem, and may be modulated in a manner that can be received by legacy components on the premises, such as analog televisions.

A system and method of providing content in a digital video network are disclosed. The system may detect the resolution capability of a user's device, and automatically configure electronic program guide (EPG), viewing and/or recording options accordingly. User preferences may also be used. Record and viewing requests may result in tuning to and decoding different datastreams.
A stereoscopic production solution, e.g., for live events, that provides 3D video asset distribution to multiple devices and networks is described. In some embodiments, live or recorded 3D video content may be accessible by different service providers with different subscribers/users and protocols across a network of the content provider. A first video signal corresponding to a first video feed for one eye of a viewer may be received and a second video signal corresponding to a second video feed for the second eye of the viewer may be received. The first video signal and the second video signal may be encoded. The encoded first video signal and the encoded second video signal may be transmitted independently over a network. The two video signals may be received and frame synced at an off-site location for eventual rendering to a display device.

CONTROL PLANE ARCHITECTURE FOR MULTICAST CACHE-FILL
A multicast content delivery system can use both multicast and unicast streams to efficiently use available bandwidth to deliver content. Available multicast content can be identified to gateways serving consumption devices, and the gateways can receive requests for unicast content deliver, but honor the requests with multicast group sessions.
To be accessed on different media players, requested content must be delivered in a format that is supported by the requesting device. A dynamic content packager for encrypting and packaging requested content for different requesting devices at the time of consumption is disclosed.
