Due to the special environment of a hospital, which needs to use inter-device communication to implement a related technical solution, prior art 3GPP paper R1-144572 discloses an inter-device communication technique, in which a first mobile terminal sends a reservation message in a first subframe within an SA cycle period of a first scheduling cycle, a second mobile terminal sends a reservation message in a second subframe within the SA cycle period of the first scheduling cycle, and both mobile terminals select to reserve at least the same subframe within a data period of the first scheduling cycle. The problems of the prior art are as follows: since it is necessary to avoid transmitting data on the overlapped subframes, the mobile terminal can transmit only the reserved resource identifier and cannot transmit the scheduling information in the SA period of the first scheduling cycle. This is because the mobile terminal does not know whether other mobile terminals will occupy their scheduled data resources, and if other mobile terminals subsequently reserve the same resources as the scheduled resources, this overlapping resource must be discarded according to the prior art method, which will result in an error in the scheduling information that the mobile terminal initially transmits. That is, in the first scheduling period, any mobile terminal can only transmit the occupation information, which wastes the resources of the SA channel and increases the scheduling delay. Simply discarding all resources involved in the overlap results in a waste of resources, which is not significant when the number of overlapping resources is small, but the number of overlapping resources cannot be only 1 subframe on 1 subband, and is excessive when the number of subframes and the number of subbands increase. The present application is directed to efficient and waste-less scheduling of inter-device communications.
