Abstract: A communication method includes sending, by a terminal device, first indication information to a first communication device. The first indication information indicates the first communication device to render first foreground content, and the first foreground content is to-be-displayed foreground content of the terminal device. The communication information also includes receiving, by the terminal device, first information from the first communication device. The first information comprises second foreground content and second background content. The second foreground content is obtained by rendering the first foreground content. The second background content is obtained by decoding third background content. The third background content is determined based on first background content. The first background content is to-be-displayed background content of the terminal device.

Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: After determining that transmission of a first data frame fails, an access stratum of a terminal sends first indication information to an application layer of the terminal, where the first indication information indicates that transmission of the first data frame fails. In other words, the access stratum of the terminal may notify the application layer of the terminal that transmission of the first data frame fails, so that the application layer of the terminal can adjust a coding scheme of a subsequent data frame in a timely manner, thereby improving a probability of successfully decoding the subsequent data frame.

Abstract: This application relates to data processing methods and apparatuses. In an example method, a receive end obtains first indication information that indicates a maximum serial number of one or more data units that are discarded. The receive end updates a value of a first variable maintained by an entity at the receive end to be greater than the maximum serial number, where the first variable may indicate that a data unit whose serial number is greater than or equal to the value of the first variable is to be processed by the entity at the receive end; or updates a value of a first variable maintained by an entity at the receive end to be equal to the maximum serial number, where the first variable may indicate that a data unit whose serial number is greater than the value of the first variable is to be processed by the entity at the receive end.

Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives first indication information from an access network device. The first indication information indicates time-frequency positions of M transmission opportunities, an amount of data that can be carried on each of the M transmission opportunities matches a data amount of a first-type video frame, and the data amount of the first-type video frame is less than a data amount of a second-type video frame. The M transmission opportunities include a first transmission opportunity, the first transmission opportunity corresponds to a first video frame, and M is a positive integer. If the first video frame belongs to the second-type video frame, the terminal device sends the first video frame to the access network device on a second transmission opportunity.

Abstract: Embodiments of this application provide a communication method and apparatus. The method includes: A first device (for example, a terminal device or a network device) determines that a first data frame is lost. The first device discards a first data packet received from an upper layer, where the first data packet is a part of or all data packets in a second data frame, the second data frame is located after the first data frame, and the second data frame is associated with the first data frame. According to the method disclosed in this application, a data frame transmission failure is identified, and proactive discarding of a data packet in a subsequent data frame associated with the lost data frame is triggered, to avoid a waste of air interface resources and transmission resources, reduce execution of unnecessary decoding operations, and reduce power consumption of the device while improving resource utilization.

Abstract: This application provides an information processing method and apparatus. In the information processing method provided in this application, a transmitter uses, as a reference data packet, an Ethernet data packet generated based on data collected by a sensor at a historical moment, establishes corresponding data tables at a receiver and the transmitter, then differentiates a first Ethernet data packet generated based on data subsequently collected by the sensor from the reference data packet to obtain deviation information, compresses the deviation information by using a preset coding algorithm to obtain compressed information for transmission, and finally transmits, to the receiver, packet identification information corresponding to the reference data packet, second identification information of a first sensor, and the compressed information, to compress the first Ethernet data packet.

The radio equipment in the communication system can be connected to a plurality of radio equipment controllers, and the radio equipment can obtain a carrier establishment request from one of the plurality of radio equipment controllers, and determine, based on the carrier establishment request, a physical resource used to establish a carrier. Because at least two radio equipment controllers correspond to different physical resources in the radio equipment, the radio equipment can determine, based on the physical resource determined based on the carrier establishment request and the physical resources corresponding to the radio equipment controllers in the radio equipment, whether to establish the carrier. Therefore, when the plurality of radio equipment controllers share same radio equipment, flexibility of managing the radio equipment by the radio equipment controller can be improved.

Abstract: An endoscopic injection needle device includes a flexible elongate sheath attached to a handle. Disposed within the sheath is drive shaft having a lumen within and a needle at its distal end. The drive shaft is movable longitudinally within the sheath and is attached at its proximal end within the handle to an actuator. Advancing the actuator extends the needle from the distal end of the device. The actuator includes a locking mechanism that locks it in place with the handle when advanced a certain distance. The locking mechanism includes multiple locking positions wherein the exposed length of the needle corresponds to the distance advanced by the actuator at each locking position. Also included in the distal end of the sheath are a spring coil and a collar. The collar is positioned distal to the spring coil and includes a dome shaped distal end that extends beyond the distal end of the sheath. The drive shaft extends through the spring coil and, when retracted, the needle is housed within the collar.
