Abstract: Embodiments provide a data exchange method, a terminal device, and a network device. In accordance with the disclosure, a terminal device can obtain resource information for communicating with another terminal device. The resource information can indicate a time-frequency resource and an antenna port corresponding to an antenna polarization direction. The terminal device can then send scheduling information and data information to the another terminal device using the time-frequency resource and the antenna polarization direction. Time-frequency resources and/or antenna polarization directions used by any two terminal devices to send scheduling information and data information to other terminal devices can be different. In this way, terminal devices using different transmit antenna ports can use a same time-frequency resource, and an optional dimension of resource information is increased, thereby increasing an overall system communication capacity.

Abstract: The present disclosure includes example device-to-device (D2D) communication methods and devices. In one example method, a user equipment (UE) sends first service cycle indication information to a base station, the first service cycle indication information indicating that a service cycle of to-be-sent data is a first cycle. The UE receives first transmission resource indication information from the base station used to indicate a first transmission resource that meets the first cycle. The UE then performs D2D communication on the first transmission resource. The UE then sends second service cycle indication information to the base station when the service cycle changes to a second cycle different than the first cycle. The second service cycle indication information indicates the change of the service cycle to the second cycle.

Abstract: Example scheduling assignment information transmission methods, systems, and devices are described. One example method includes obtaining, by a user equipment (UE), a multiplexing manner used to indicate a relationship between a time-frequency resource for transmitting scheduling assignment information and a time-frequency resource for transmitting data information. The UE receives downlink control information comprising scheduling assignment resource indication information sent by a network device, and obtains, based on the scheduling assignment resource indication information and the multiplexing manner, resource location information occupied to transmit the scheduling assignment information. The UE can then transmit the scheduling assignment information based on the resource location information occupied by the scheduling assignment information.
