Abstract: Example uplink control information sending methods, network devices, and terminals are described. In one example method, a terminal determines physical uplink control channel PUCCH channel resource configuration information. The PUCCH channel resource configuration information is used to instruct the terminal to send uplink control information based on a configured PUCCH channel resource, and the PUCCH channel resource configuration information is preconfigured, or is sent by a network device. The terminal sends the uplink control information based on the PUCCH channel resource configuration information using the configured PUCCH channel resource. The uplink control information includes one or a combination of downlink data acknowledgement information, a downlink channel state information, a scheduling request, and buffer state information.

Abstract: Embodiments of the present disclosure include example device-to-device communication methods and terminal devices. One example method includes determining, by a terminal device, a first resource, where the first resource is some time-frequency resources in a first resource set, where the first resource set is all time-frequency resources that can be used to detect a first transmission resource. The first transmission resource is a spectrum resource used to transmit first data. The terminal device can then perform detection for the first transmission resource in the first resource. In some instances, the terminal device can then send first data on the first transmission resource.

Abstract: Embodiments disclose a signal processing method and a network device, so as to number a transmission time interval (TTI) in a frame structure and generate a signal sequence by using a number of the TTI. The method includes: determining a number of a transmission time interval TTI in a frame structure, where the TTI includes a time length less than 1 millisecond; and generating a signal sequence of the TTI based on the number of the TTI. The number of the TTI less than 1 millisecond or equal to 1 millisecond in the frame structure is determined, and the signal sequence of the TTI is generated based on the number of the TTI. This prevents interference between adjacent or neighboring TTIs or intersymbol interference (ISI) from being generated due to generation and use of a same signal sequence because for all short TTIs.
