The resource determination function may be the same or different between the first and second sets of TD-OCCs, i.e., (9) (10) and (11) (12) may be the same or different.
Based on the above concept that resources occupied by ports in time frequency units of different configuration types can be determined based on the absolute sequence number of a scheduling time unit, i.e., the timeslot number of the system, the present application provides a time frequency resource configuration method, which refers to the flowchart of the method shown in fig. 2, including but not limited to the following steps.
S201, the network device sends first information to the terminal, where the first information may include an absolute sequence number of a scheduling time unit.
S202, the terminal determines the resources occupied by the target port on the target time frequency unit according to the absolute sequence number of the scheduling time unit. The target port may be scheduled to the terminal by the network device, and the target time-frequency unit may be a time-frequency unit corresponding to the scheduling time unit.
For example, when the type of the time frequency unit is the first configuration type, the determination function that the port occupies the resource in the time frequency unit is equation (1), and the port scheduled by the network device to the terminal is port 1, if the absolute sequence number of the scheduling time unit sent by the network device to the terminal is slot number 1 of the system, the terminal determines, with reference to the embodiment shown in fig. 1A, that the port n-1 occupies the resource in the time frequency unit corresponding to the slot number k-1 of the system, and the resource may be used to carry the reference signal.
For another example, when the type of the time-frequency unit is the second configuration type, the determination function that the port occupies the resource in the time-frequency unit is equation (2), and the port scheduled by the network device to the terminal is port 1, if the absolute sequence number of the scheduling time unit sent by the network device to the terminal is slot number 1 of the system, the terminal determines, with reference to the embodiment shown in fig. 1B, that the port n-1 occupies the resource in the time-frequency unit corresponding to the slot number k-1 of the system, and so on.
It should be noted that, in this application, the network device may only schedule the absolute sequence number of one scheduling time unit each time it schedules, and the terminal may only determine, according to the absolute sequence number of the scheduling time unit, the resource occupied by the port on the target time-frequency unit corresponding to the absolute sequence number of one scheduling time unit each time. For example, the network device may schedule only one absolute sequence number of the scheduling time unit, such as the timeslot number 1 of the system, each time it schedules.
In this embodiment of the present application, the type of the time frequency unit and the determining function of the resource occupied by the port on the time frequency unit may be notified to the terminal by the network device, or may be specified in a standard or a protocol of the system, which is not limited herein.
In the embodiment of the application, the terminal can determine the resources occupied by the ports according to the absolute serial numbers of the scheduling time units, so that the network equipment can schedule only one scheduling time unit at each time, and when the network reverse link data is transmitted, the network equipment can schedule the time units in time for reverse transmission, thereby improving the flexibility of scheduling the system resources.
Optionally, the first network device may further determine, according to the absolute sequence number of the scheduling time unit, resources occupied by the target port in the target time-frequency unit, where the target port may be scheduled by the second network device to the terminal, and it may be understood that the second network device may be the same as or different from the first network device. Specifically, the first network device determines, according to the type of the time-frequency unit, the determination function of the resource occupied by the target port in the time-frequency unit, and the absolute sequence number of the scheduling time unit, the resource occupied by the target port in the target time-frequency unit, and the like, where descriptions of the determination method for the resource occupied by the target port in the target time-frequency unit may be shown in fig. 1A to 1F, and are not repeated here.
Optionally, in order to avoid using OCCs for distinguishing between ports as much as possible and ensure performance of channel estimation, if the first network device schedules a target port for a terminal, the first network device preferentially schedules a port consistent with a TD-OCC corresponding to the target port for the terminal again; and if the port which is consistent with the TD-OCC corresponding to the target port is scheduled, the first network equipment schedules the port which is inconsistent with the TD-OCC corresponding to the target port for the terminal. For example, when the type of the time-frequency unit is the second type, if the target port scheduled by the first network device for the terminal is port 1 in fig. 1B, the first network device may preferentially schedule port 2, port 3, or port 4 that is consistent with the TD-OCC corresponding to port 1 for the terminal, and if the port that is consistent with the TD-OCC corresponding to port 1 is scheduled completely, the first network device may schedule port 5, port 6, port 7, or port 8 that is inconsistent with the TD-OCC corresponding to port 1 for the terminal again. When the type of the time-frequency unit is a fourth type, if the target port scheduled by the first network device for the terminal is port 1 in fig. 1E, the first network device may preferentially schedule port 2, port 3, port 4, port 5, or port 6 that are consistent with the TD-OCC corresponding to port 1 for the terminal, and if the port that is consistent with the TD-OCC corresponding to port 1 is scheduled completely, the first network device may schedule port 7, port 8, port 9, port 10, port 11, or port 12 that are inconsistent with the TD-OCC corresponding to port 1 for the terminal again.
The type of the time-frequency unit is a second type, when the first network device schedules a port consistent with the TD-OCC corresponding to the target port for the terminal, the first network device may preferentially schedule a port consistent with the TD-OCC corresponding to the target port and consistent with the cyclic shift for the terminal, and if the port consistent with the TD-OCC corresponding to the target port and consistent with the cyclic shift is scheduled, the first network device schedules a port consistent with the TD-OCC corresponding to the target port and inconsistent with the cyclic shift for the terminal. For example, when the type of the time-frequency unit is the second type, if the target port scheduled by the first network device for the terminal is port 1 in fig. 1B, the first network device may preferentially schedule port 3 for the terminal, which is consistent with the TD-OCC corresponding to port 1 and consistent with the cyclic shift, and if port 3 is already scheduled, the first network device may schedule port 2 or port 4 for the terminal, which is consistent with the TD-OCC corresponding to port 1 and inconsistent with the cyclic shift.
Optionally, in order to avoid using the OCCs for distinguishing between the ports as much as possible and ensure the performance of channel estimation, if the first network device schedules a target port for the terminal, the first network device preferentially schedules a port consistent with the FD-OCC corresponding to the target port for the terminal again; and if the port which is consistent with the FD-OCC corresponding to the target port is scheduled, the first network equipment schedules the port which is inconsistent with the FD-OCC corresponding to the target port for the terminal. For example, when the type of the time-frequency unit is the third type, if the target port scheduled by the first network device for the terminal is port 1 in fig. 1D, the first network device may preferentially schedule port 3 or port 5 that is consistent with the FD-OCC corresponding to port 1 for the terminal, and if the port that is consistent with the FD-OCC corresponding to port 1 is scheduled completely, the first network device may schedule port 2, port 4, or port 6 that is inconsistent with the FD-OCC corresponding to port 1 for the terminal.
