    Abstract: Embodiments of this application provide example data transmission methods. One example method includes: receiving, by a receiving device, first data on a first time-frequency resource, and receiving second data on a second time-frequency resource. When the first time-frequency resource and the second time-frequency resource have an overlapped target frequency domain resource in frequency domain, the receiving device can then use a first DMRS mapped to a target frequency domain resource of the first time-frequency resource to demodulate the second data mapped to a target frequency domain resource of the second time-frequency resource.

    Abstract: This application provides a control information transmission method, and relates to the field of wireless communications. The method includes: determining, by a terminal device, whether to monitor an uplink preemption indication (PI) based on whether a time-frequency resource used to transmit uplink data overlaps a reference uplink resource (RUR), to effectively avoid blind detection performed on the uplink PI by terminal devices that do not need to receive the uplink PI, and reduce overheads of blind detection performed on the uplink PI by the terminal devices.

    Abstract: A system and method for multiplexing traffic. A wireless device such as a base station may schedule a first transmission of first data (e.g., latency tolerant data) to a first UE on first resources, and transmit second data (e.g., low latency data) to a second UE on a portion of the first resources. The base station may signal a first indicator e.g. via Radio Resource Control (RRC) signaling to the first UE indicating that the first UE is to monitor for a second indicator that itself indicates the presence of second data on the first resources. The base station may then signal a second indicator to the first UE to indicate the presence of the second data on the first resources. By using the first indicator to initiate the monitoring of the second indicator, the first UE can reduce the amount of monitoring it needs to perform if there is no second data traffic in a certain period of time or in a certain frequency band.

    Abstract: A data input method and apparatus, and user equipment are provided. The method includes: when it is determined that an operation of a user on the user equipment UE is not performed in a preset display area, deliver an event corresponding to the operation to a first operating environment for processing, where the preset display area runs in a second operating environment of the UE, and the second operating environment has a higher security level than the first operating environment. This can better improve security of an event generated when the user operates a program that runs in a Normal World of the user equipment, and can directly operate an event that runs in the Normal World.

    Abstract: The present disclosure relates to the communications field, and specifically, to a flow table processing method and an apparatus. The method includes: monitoring, by a switch, a flow table load of the switch; when the flow table load of the switch exceeds a preset threshold, determining, by the switch, a diffusion target of a target data flow according to a matching rule of a diffusive flow table; and when the determined diffusion target is a neighboring switch of the switch, forwarding, by the switch, the target data flow to the neighboring switch. When the flow table load of the switch exceeds the preset threshold, the switch may have been attacked. A data flow that fails to be matched to a flow entry is forwarded to the neighboring switch according to a diffusion probability, for processing by the neighboring switch.
