Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support hybrid automatic repeat request (HARQ) schemes to improve the likelihood that information is received correctly over a wireless communications link. In HARQ, when a transmitting device determines that a receiving device failed to successfully decode a transmission of information, the transmitting device may retransmit the information to the receiving device. In some cases, HARQ techniques may be used for communications associated with different types of services. In such cases, to keep the latency of communications within a latency budget for a particular type of service, wireless devices may utilize the techniques described herein to dynamically terminate HARQ retransmissions. For instance, a transmitting device may avoid retransmitting information when an amount of time that has elapsed since an original transmission of the information has exceeded the latency budget.

A method of transmitting messages from a sender to a recipient over a wireless channel, the messages including a sequence counter and a frame counter. The method comprises establishing initial values of the sequence counter and the frame counter at the sender. Initial values of the frame counter and the sequence counter are provided to the recipient. The sender sends compressed messages including the value of the sequence counter and not the frame counter and monitors for an acknowledgement of receipt by the recipient. When no acknowledgment is received, the sender sends uncompressed messages until an acknowledgement of receipt is received from the recipient. The sequence counter is incremented and the next value of the frame counter is established as the integer next larger than previous value of the frame counter which is congruent to the sequence counter modulo 256.

A vital-signs patch for a patient monitoring system that includes a housing containing a sensor that makes physiological measurements of a patient, a transmitter, a receiver, a memory, and a processor. The processor periodically takes a measurement from the sensor, converts the measurement to a data record, and stores the data record in the memory. Upon receipt of a signal from another device, the processor retrieves at least a portion of the data record, converts the retrieved portion of the data record to a vital-sign signal, and causes the transmitter to transmit the vital-sign signal to the other device.

This application provides a data transmission method and related apparatus. The data transmission method is applied to a communications system. An access point in the communications system includes a first communications apparatus and a second communications apparatus, and a station in the communications system includes a third communications apparatus and a fourth communications apparatus. The data transmission method includes that after failing to send a first data frame to the third communications apparatus through a first channel, the first communications apparatus retransmits the first data frame, and sends a same second data frame to the second communications apparatus. The first communications apparatus receives a first notification message sent by the second communications apparatus. The first communications apparatus stops, in response to the first notification message, sending the first data frame.

A data scan system is introduced, including an electronic device including a data scan module. The data scan module includes a data capture unit and a data processing control unit. The data capture unit is used to capture a target data and assign a plurality of corresponding labels to the target data. The data processing control unit is coupled to the data capture module, and includes an exception processing sub-unit for performing an exception processing mechanism on the target data, a control status switching sub-unit, a backup sub-unit, and a remote control sub-unit, an error report sub-unit, a flow monitoring sub-unit and a shortest path handling sub-unit. It can greatly improve the degree of control over the subsequent processing of data, thereby achieving the purpose of improving the security of data transmission.
