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.

Abstract: The present invention discloses a resource reuse apparatus, user equipment, and a resource reuse method. The method includes: monitoring, by first user equipment, idle resources so as to obtain a first idle resource set; claiming, in a first cycle, to use a first resource, where the first resource is a resource in the first idle resource set; determining whether the first resource exists in a first claimed resource set, where the first claimed resource set is a set of resources that are claimed to be used by another user equipment except the first user equipment; and if the first resource exists in the first claimed resource set, claiming, in a second cycle, to use a second resource, where the second resource is a resource, in the first idle resource set, that is different from the first resource; or reclaiming a resource after at least one cycle following the first cycle.

Abstract: A communication control method and a related apparatus are disclosed. A communication control method includes transmitting, by a base station, a configuration message to N user terminals in a cell, where the configuration message carries a secondary configuration indication, and the secondary configuration indication is used to indicate a secondary transmission configuration configured by the base station for the N user terminals, where the secondary transmission configuration of the N user terminals is different from a primary transmission configuration of M user terminals in the cell. The method also includes obtaining, by the base station, interference parameters about interference that the N user terminals receive from neighboring user terminals in a full-duplex subframe, and activating the secondary transmission configuration for K user terminals in the N user terminals by using an activation message.
