A method for selecting subframes of single-cell transmission of Multimedia Broadcast Multicast Service (MBMS) is provided by the present invention. The method includes: the base station only uses subframes that cannot be used for multi-cell transmission of MBMS service to transmit single-cell MBMS service; or when the subframes that cannot be used for multi-cell transmission of MBMS service are not enough for the base station to transmit single-cell MBMS service, it is judged if subframes that are not used for multi-cell transmission of MBMS service are present, and if present, subframes that are not used for multi-cell transmission of MBMS service are selected to transmit single-cell MBMS service. Using the method of the present invention, the conflict of the subframe configuration is avoided when single-cell transmission of MBMS service and multi-cell transmission of MBMS service are performed. The schedule of the resources of MBMS service in the whole system is more convenient, the schedule of the resources is favorable to be implemented when multi-cell transmission of MBMS service is performed, and the high efficiency of the whole MBMS system is implemented.

The invention discloses a method of predicating time duration. The method comprises the following steps: acquiring waiting time duration of to-be-executed tasks in a distributed system and execution time duration of executing the to-be-executed tasks, wherein the waiting time duration of one task is a time duration interval between the current time and the execution starting time of one task, and the execution time duration of one task is a time duration interval between the execution starting time and the execution finishing time of one task; acquiring residual time duration of the to-be-executed tasks according to the waiting time duration and execution time duration of the to-be-executed tasks, wherein the residual time duration of one task is a time duration interval between the current time and the execution finishing time of one task. By applying the method disclosed by the invention, the residual time duration of the to-be-executed tasks can be obtained, i.e., the time duration interval between the current time and the execution finishing time of each to-be-executed task is obtained, and thus subsequent resource scheduling and other task arrangement can be facilitated.

The invention discloses a method for detecting path loss. The method comprises the following steps that: a base station sends SNPL detection information on the path loss of a neighbor cell; a terminal detects the pass loss of the adjacent cell having the same frequency as the terminal according to the SNPL detection information, and works out an SNPL value; and the terminal sends the SNPL value to the base station. The invention also discloses a system and the equipment for detecting the path loss. According to the technical scheme provided by the invention, the terminal can accurately detectthe path loss the neighbor cells with the same frequency, the system can accurately understand the communication environment of the current terminal, the resource allocation of the system can be conveniently made, and simultaneously the uplink interference control by the system can also be made convenient.

The present invention provides a method for scheduling resources based on beam hopping, which includes the following steps: dividing the satellite coverage area into multiple cells; dividing each cell into multiple rectangular units of equal size; representing each The actual channel capacity of the rectangular unit at different times; use the second three-dimensional matrix to indicate whether to serve each rectangular unit at different times, wherein element 1 of the second three-dimensional matrix indicates that the corresponding rectangular unit is served by hopping beams at a certain time, and element 0 Indicates that the corresponding rectangular unit is not served at a certain moment; the target matrix is ​​represented by the product of the first three-dimensional matrix and the second three-dimensional matrix; the second three-dimensional matrix is ​​adjusted so that the sum of all elements of the target matrix is ​​the largest; and according to the adjusted second The three-dimensional matrix serves the corresponding rectangular unit. Through this method, the allocation of beam-hopping beam resources in each satellite coverage area can be optimized for the scene of fast moving low-orbit satellites, so as to better schedule precious space resources.
