Abstract: A communication system includes a control wireless station. One or more data payload-conveying wireless stations rely on the control wireless station to provide control information to a mobile communication device to control conveyance of data over one or more data channels to the mobile communication device. For example, to connect to a remote network, a mobile communication device establishes a first wireless communication link with the control wireless station. The mobile communication device establishes a second wireless communication link with a data conveying wireless station. The first wireless link conveys control information from the control wireless station to the mobile communication device. The second wireless link conveys data payload information. The control information conveyed over the first wireless link controls conveyance of the data payload information over the second wireless communication link.

Abstract: An apparatus includes a first communication device with multiple antennas, operably coupled to a processor and configured to access a codebook of transformation matrices. The processor generates a set of symbols based on an incoming data, and applies a permutation to each of the symbols to produce a set of permuted symbols. The processor transforms each of the permuted symbols based on at least one primitive transformation matrix, to produce a set of transformed symbols. The processor applies, to each of the transformed symbols, a precode matrix selected from the codebook of transformation matrices to produce a set of precoded symbols. The codebook of transformation matrices is accessible to a second communication device. The processor sends a signal to cause transmission, to the second communication device, of multiple signals, each representing a precoded symbol from the set of precoded symbols, each of the signals transmitted using a unique antenna from the plurality of antennas.

Abstract: 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.

Abstract: An apparatus, method, system, and computer-readable medium are provided for enhancing the quality of content. A determination may be made that a portion of the content received using a base feed or bitrate completed early. In response to that determination, an attempt may be made to download that portion of the content using a differential bitrate or feed corresponding to a higher quality. Another determination may be made whether the differential bitrate or feed download completed early, and if so, then the differential bitrate or feed may be used as a new base bitrate or feed for downloading additional portions of the content. The differential bitrate or feed download may also provide for a secondary playback of the content at higher quality.

Abstract: A data system is provided for analyzing and maintaining data obtained from one or more data sources on which the data system depends. The system includes a primary database including current values used by the system and a collection of executable algorithms used to generate the data maintained in the primary database. In response to receiving a notification regarding a change in one of the data sources, a dependency database is used to establish an execution order for algorithms of the algorithm collection that are directly or indirectly dependent on the changed data. The algorithms identified in the execution order are then executed in accordance with the execution order and the corresponding result is stored in the primary database. The system may include data harvesters adapted to recognize changes in the data sources and to generate and transmit corresponding change notifications when such changes occur.
