Abstract: Systems, apparatuses, and methods are described for wireless communications. A base station may transmit indications of target received powers for a random access procedure and a beam failure recovery procedure. A wireless device may transmit a random access preamble and a beam failure recovery preamble using different transmission powers based on the indications of target received powers.

Abstract: Aspects described herein relate to wireless communications. According to some aspects, a first base station may coordinate with a second base station to select beamforming codewords. The first base station may receive an index indicating beamforming codewords used by a second base station. The first base station may select a beamforming codeword for use in transmitting signals to a wireless device based on the beamforming codeword indicated by the second base station.

Abstract: Systems, apparatuses, and methods are described for wireless communications. A wireless device may select a reference signal and/or random access channel resource based on configuration parameters for a beam failure recovery procedure. A base station may send configuration parameters using a medium access control (MAC) control element (CE).

Abstract: Methods and systems for content optimization are described. A computing device may determine a predictability score that indicates a probability that a device will access a first content item. The computing device may send a second content item associated with the first content item. The second content item may be based on the predictability score, and the predictability score may be modified. Additional content consumption and/or recommendations may be adjusted based on the predictability score.

Abstract: Uplink resources for semi-persistent channel state information (SP-CSI) reports and other uplink transport block transmissions may be managed. If resources allocated to the SP-CSI reports overlap, in time, with resources allocated to the uplink transport block transmissions, a determination of whether to drop an SP-CSI report may be made. Various selection criteria may be used to make this determination.

Abstract: Systems, apparatuses, and methods are described for preauthorizing a batch of access rights licenses, e.g., Digital Rights Management (DRM) licenses, and storing them at a location. The preauthorization may be based on predicting a batch of content items to be viewed. The location may be a content server or a user device. After receiving a request from the user device to play back a content item of the batch of predicted content items, the DRM license may be provided from the storage location instead of performing an authorization operation to obtain one from a DRM server. Providing the DRM license from the storage location may take less time than performing the authorization operation to obtain the DRM license from the DRM server.

Abstract: Systems, methods, and apparatuses are described for authenticating a user device and/or user application. A user device may receive, based on a first authentication request, a plurality of messages sent over a plurality of channels of communication (e.g., a message to a URL address associated with the user device and a binary Short Message Service (SMS) message). Based on information from the messages, the user device may transmit a second authentication request.

Abstract: According to some aspects, disclosed methods and systems may include having a user input one or more speech commands into an input device of a user device. The user device may communicate with one or more components or devices at a local office or headend. The local office or the user device may transcribe the speech commands into language transcriptions. The local office or the user device may determine a mood for the user based on whether any of the speech commands may have been repeated. The local office or the user device may determine, based on the mood of the user, which content asset or content service to make available to the user device.

Abstract: Delay in output of a requested content asset by a user device may be reduced by sending a portion of the content asset to the user device in a particular type of format, such as an unsecured format. The unsecured portion of the content asset may be sent to the user device while a license for the content asset is being processed. The size of the unsecured portion of the content asset may be determined based on a time for the user device to receive the license. The time for the user device to receive the license may be determined based on a time to process the license. After sending the license to the user device, another portion of the content asset may be sent to the user device in a secured format. The user device may use the license to access the secured portion of the content asset.

Abstract: A wireless device may receive at least one message comprising configuration parameters of a plurality of cells being in a cross-carrier scheduling group comprising a first cell and a second cell. The first cell identified by a first cell identifier may employ a first number of bits. The configuration parameters may indicate that the second cell is a cross-carrier scheduling cell for the first cell. The configuration parameters may comprise the first cell identifier and a first cell indicator field. The first cell indicator field may employ a second number of bits. The wireless device may receive downlink control information via a control channel of the second cell for a packet transmitted via the first cell. The downlink control information may comprise the first cell indicator field identifying the first cell. The wireless device may receive the packet on the first cell via radio resources identified by the downlink control information.

Abstract: 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.

Abstract: Systems, apparatuses, and methods are described for wireless communications. A wireless device may distribute power for various transmission types based on a priority, which may be received from a base station.

Abstract: Wireless communications may use a plurality of cell groups. A downlink-uplink cell may be assigned to each cell group of a plurality of cell groups, and each of a plurality of downlink-only cells may be assigned to a cell group of the plurality of cell groups. A wireless device may transmit an uplink signal via a downlink-uplink cell based on a timing advance command.

Abstract: A method of data conditioning is disclosed that in one aspect can include the steps of receiving a data stream, encoding a time code in the data stream to identify a portion of the data stream corresponding to a content fragment, and separating the identified portion of the data stream to define the content fragment, wherein the content fragment comprises the encoded time code.

Abstract: A wireless device may receive configuration parameters of cells comprising a primary cell that is not configured with scheduling request (SR) resources and a secondary cell that is configured with SR resources and that is in a secondary timing advance group (sTAG). A wireless device may determine to perform an SR process. Based on the wireless device not having an uplink data channel resource available in a time interval and not having a valid timing advance for the secondary cell in the time interval, the wireless device may initiate a random access procedure.

Abstract: Disclosed are methods and systems for providing content. An example method can comprise receiving, at a content provider, a request for a content transmission from a first device and determining a parameter related to the first content transmission and comparing the parameter to a threshold. An example method can comprise determining, by the content provider, a second content transmission based on the comparison to the threshold and providing the second content transmission to the first in response to the request.

Abstract: An encoder may determine one or more encoding characteristics associated with a content segment of a content asset. The one or more encoding characteristics may comprise an estimated bitrate required for transmission of the content segment over a network. The one or more encoding characteristics associated with the content segment may be inserted into a portion of an other content segment, such as into a header of the other content segment. The content segment and the other content segment may be configured for linear transmission, such as using adaptive bitrate streaming. When the other content segment is received at a playback device prior to the content segment, the playback device may use the one or more encoding characteristics of the content segment embedded in the header of the other content segment to determine one or more playback characteristics of the content segment.

Abstract: A wireless device may receive radio resource control (RRC) messaging comprising a field indicating a starting symbol for a physical downlink control channel (PDCCH). The wireless device may monitor for at least one PDCCH candidate. A PDCCH candidate may start based on a listen-before-talk (LBT) procedure, the starting symbol, and the offset value.

Abstract: Wireless communications are described. A central unit control plane (CU-CP) node of a base station may activate and/or deactivate packet duplication based on status information from self-monitoring, from a distributed unit (DU), from a wireless device, and/or from a central unit user plane (CU-UP) node. The CU-UP node and/or the DU may activate and/or deactivate packet duplication based on status information from self-monitoring, from each other, from the wireless device, and/or from the CU-CP node. The CU-UP node and/or the DU, after activating and/or deactivating packet duplication, may report the activation and/or deactivation to the CU-CP node.

Abstract: A computing device may provide content items to user devices requesting the content items. The computing device may receive the content item, in portions, from a source, and may send the portions to the user device. The computing device may send a first portion before the computing device receives all of the content item from the source. The request may also be associated with an expiration period, and the expiration period may affect the sending of the content item to the user device.
