In this embodiment, after determining the second frequency domain resource, the terminal sends an uplink service to the network device according to the second frequency domain resource.

A possible implementation manner of the S104 is that the terminal uses the second frequency domain resource for the terminal to send the uplink service, that is, the terminal sends the uplink service to the network device on the second frequency domain resource.

A feasible implementation manner of the S104 is: the terminal determines the frequency domain resource that the terminal actually uses for the uplink service transmission from the second frequency domain resource. For the specific implementation process, refer to the related description in the following embodiments. No longer. The terminal then transmits data to the network device on the frequency domain resource that is actually used for uplink traffic transmission. The frequency domain resource actually used for uplink service transmission belongs to the second frequency domain resource (which may be part of the second frequency domain resource, or may be all second frequency domain resources).

In this embodiment, since the first frequency domain resource is indicated by the network device to the terminal, the first frequency domain resource is determined by the network device, and may be changed according to the actual network situation, and is no longer fixed. The terminal can determine a suitable frequency domain resource for transmitting the uplink service from the variable first frequency domain resource, thereby reducing the collision probability of each terminal uplink service transmission, reducing the delay, and saving network resources.

Optionally, a feasible implementation manner of the foregoing S102 is: the terminal determines, according to the second indication information, a size of the first target frequency domain resource.

For example, the second indication information is used to indicate the correspondence between the size of each uplink service and the size of each of the first target frequency domain resources, and the terminal determines, according to the size of the uplink service sent in S104 and the corresponding relationship indicated by the second indication information.

Optionally, a feasible implementation manner of the foregoing S102 is: determining, by the terminal, the size of the first target frequency domain resource according to the size of the first frequency domain resource.

For example, the terminal determines, according to the size of the first frequency domain resource, the size of a frequency domain resource from the first set as the size of the first target frequency domain resource, where the first set includes the size of at least one frequency domain resource, and each frequency The size of the domain resources is different. The first set is, for example, {1 RB, 2 RB, 4 RB, 8 RB, .... kRB}. Other multiples are not excluded, and other possible set forms are not excluded. The first set may be specified in a communication protocol or sent by the network device to the terminal.

The size of the domain resource. Optionally, the terminal may also be the first according to the current uplink service size and the current delay requirement. The size of one frequency domain resource is determined in the set as the size of the first target frequency domain resource.

The first coefficient is a number less than 1 and greater than 0; the size of the first frequency domain resource is substituted into a preset formula, and the obtained value is the size of the first target frequency domain resource.

Optionally, the terminal may further determine the second frequency domain resource from the first frequency domain resource according to at least one of a physical cell identifier, a terminal identifier, a current subframe number, and a current slot number. Optionally, the terminal may further determine the second frequency domain resource from the first frequency domain resource according to the current uplink service size or the current delay requirement.

Optionally, a possible implementation manner of the S103 is: determining, by the terminal, the first resource set according to the first frequency domain resource and the size of the first target frequency domain resource, where the first resource set is Include at least one first sub-resource, the size of each first sub-resource is the same as the size of the first target frequency-domain resource, and the location of each first sub-resource is different; and the terminal is from the first resource A first sub-resource is determined in the set as the second frequency domain resource.

The frequency domain resource of the size of the target frequency domain resource is used as the first sub-resource in the first resource set. For example, the size of the first target frequency domain resource is 5 RBs, and each first sub-resource in the first resource set is a frequency domain resource of each consecutive 5 RB in the first frequency domain resource. It should be noted that the embodiment is not limited thereto.

The first feasible implementation manner of determining, by the terminal, a first sub-resource from the first resource set as the second frequency domain resource, is that the terminal randomly selects one from the first resource set. The first sub-resource is used as the second frequency domain resource. Regardless of whether the uplink service is a first transmission service or a retransmission service, the terminal arbitrarily selects a first sub-resource from the first resource set as the second frequency domain resource.

The second feasible implementation manner of determining, by the terminal, a first sub-resource as the second frequency domain resource from the first resource set is: when the uplink service is a first-transmission service, the terminal is Any one of the first resource sets is arbitrarily selected as the second frequency domain resource.

The third feasible implementation manner of determining, by the terminal, a first sub-resource as the second frequency domain resource from the first resource set is: when the uplink service is a retransmission service, according to the Determining, by the first resource set, at least one of the frequency domain resources available for the uplink service transmission, and determining, by the first resource set, a first sub-resource as the second frequency domain resource; N is an integer greater than zero. For example, the second frequency domain resource obtained in this embodiment is not completely the same as the at least one of the frequency domain resources available for uplink service transmission in the first N times of transmission; thus, the first uplink service and the retransmission uplink service can be enabled. Obtain a frequency grading gain.

The size of the resource is the size of the second target frequency domain resource.

For example, the terminal acquires the size of the second target frequency domain resource according to the size of the first frequency domain resource or the size of the second frequency domain resource, and a preset formula, where the preset formula is, for example, the size of the first frequency domain resource multiplied by The value obtained by a coefficient is further rounded, and the second coefficient is a number less than 1 and greater than 0; the size of the first frequency domain resource is substituted into a preset formula, and the obtained value is the size of the second target frequency domain resource. Alternatively, the preset formula is, for example, the size of the second frequency domain resource multiplied by the value obtained by the third coefficient, and the third coefficient is a number less than 1 and greater than 0; and the size of the second frequency domain resource is substituted into the preset formula. The value obtained is the size of the second target frequency domain resource.

Each of the second sub-resources belongs to the second frequency domain resource.

The method for determining, by the terminal, the second resource set according to the second frequency domain resource and the size of the second target frequency domain resource is: the terminal is consecutively second from the second frequency domain resource.

For example, the third frequency domain resource obtained in this embodiment is not completely the same as the at least one of the frequency domain resources actually used for uplink service transmission when the previous M times are sent; In this way, the first-level uplink service and the re-transmitted uplink service can obtain the frequency grading gain.

The terminal may determine a suitable frequency domain resource that can be used for uplink service transmission from the variable first frequency domain resource, and then determine a frequency domain resource that is actually used for uplink service transmission, thereby reducing uplink service transmission of each terminal. The collision probability of time reduces the delay and saves network resources.
