摘要： An electronic device is provided. The electronic device includes a first subscriber identity module (SIM), a second SIM, and a processor. The processor is configured to merge a first signal from the first SIM and a second signal from the second SIM and transmit the first signal and the second signal through a radio frequency front end (RFFE) transmission path concurrently, in response to a determination that the first signal and the second signal are intra-band signals and the first SIM and the second SIM share one RFFE transmission path.

摘要： A method of delivering media content, where a streaming server provides a media content to a streaming client. The media content includes multiple media tracks. A first group of entities is specified for the media content. Each entity in the first group of entities is a media track, an item, or a child group of entities. A first data structure is populated to specify one or more arrays of entity identifiers for the first group of entities. Each array of entity identifiers has one or more identifiers of the entities in the first group. Each array of entity identifiers is associated with one reference type that describes the entities identified by the array of entity identifiers. The first data structure is provided to the streaming client, which provides entities of the first group from the media content for playback according to the first data structure.

摘要： Aspects of the disclosure provide a method, an apparatus, and a non-transitory computer-readable medium for compressing channel state information (CSI). Under the method, a CSI matrix is decomposed, at a first device, into a first vector including a plurality of significant numbers extracted from the CSI matrix. A second vector is generated by multiplying the first vector with a linear operator. A length of the second vector is less than a length of the first vector. The second vector is sent from the first device to a second device along with a number of the plurality of significant numbers in the first vector. The method is implemented in software instructions, and when processing circuitry of the apparatus executes the software instructions, the processing circuitry of the apparatus performs the method. The software instructions are stored in the non-transitory computer-readable medium.

摘要： The invention provides method and apparatus augmenting functionality of an antenna-in-module (AiM) of a user equipment (UE) to proximity detection (and more) besides wireless communication. The AiM may comprise a radiator set and a channel circuit set. The radiator set may comprise one or more radiators, and the channel circuit set may comprise one or more channel circuits. The method may comprise: causing a first subset of the channel circuit set to transmit outgoing electromagnetic (EM) waves by circular polarization of a first rotation sense, causing a second subset of the channel circuit set to receive incoming EM waves by circular polarization of a second rotation sense different from the first rotation sense, accordingly obtaining one or more received detection signals, and executing the proximity detection according to the one or more received detection signals.
