In order to solve the problem that uplink transmission scheduled by a PDCCH overlaps with a Configured grant and the uplink transmission scheduled by a prioritized PDCCH affects high-priority data transmission in a service with a delay requirement in the prior art, an embodiment of the present invention provides an uplink resource scheduling method, which indicates, through a configuration information identifier in resource configuration information of a target logical channel Configured by an RRC, whether a priority of an uplink resource based on the Configured scheduled Configured grant is higher than an uplink resource scheduled by a physical downlink control channel PDCCH, so as to ensure rationality of uplink resource scheduling, and avoid the problem that the uplink transmission scheduled by the PDCCH is preferentially performed and the high-priority data transmission in the service with the delay requirement is affected.

The uplink resource scheduling method according to an embodiment of the present invention is applied to a terminal, and as shown in fig. 2, the method includes:

s210, acquiring resource configuration information of a target logical channel configured by a Radio Resource Control (RRC);

Optionally, in step S210, when the configuration information is identified as a preset character, it indicates that the priority of the uplink resource based on the Configured grant is higher than the uplink resource scheduled by the PDCCH.

For example, the preset character may be true or may be enable.

Optionally, the configuration information identifier may indicate that the priority of the uplink resource based on the Configuredgrant is higher than that of the uplink resource scheduled by the PDCCH only by using preset characters; when the priority of the uplink resource based on the Configured grant is not higher than the uplink resource scheduled by the PDCCH, the resource configuration information may not include the configuration information identifier, that is, does not include the preset character.

Optionally, the configuration information identifier indicates that a preset character of the uplink resource based on the Configured grant, the priority of which is higher than that of the uplink resource scheduled by the PDCCH, is a first preset character; the priority of the uplink resource based on the Configured grant may be further represented by a second preset character different from the first preset character, to be not higher than the uplink resource scheduled by the PDCCH.

Optionally, in step S210, the resource allocation information is used to allocate a Configured grant of a first type or a Configured grant of a second type for the target logical channel.

It should be noted that the uplink resources of the target logical channel Configured by the network side device through the RRC may include two types, one of which is a Configured grant of the second type, and the PDCCH may activate and deactivate the use of the uplink resources; the other is a Configured grant of the first type, which does not require activation and deactivation of uplink resource usage by the PDCCH, wherein the first type Configured grant is Allowed to use a Configured grant type1Allowed parameter in the resource configuration information (e.g., Logical Channel configuration can be Configured for Logical channels) to indicate whether the corresponding target Logical Channel can be Allowed to use the Configured grant of the first type.

When the configurable granttype1Allowed parameter is set to true, it indicates that the target logical channel may be Allowed to use the Configured grant of the first type, and when the configurable granttype1Allowed parameter is set to false, it indicates that the target logical channel is not Allowed to use the Configured grant of the first type.

Optionally, when the configurable granted type1Allowed parameter is true, it indicates that the priority of the uplink resource based on the Configured scheduled Configured grant is higher than the uplink resource scheduled by the physical downlink control channel PDCCH, and the target logical channel may use the Configured grant of the first type Configured by the resource configuration information, and the logical channel group where the target logical channel is located has the cache data.

Specifically, when the resource configuration information is used to configure the Configured grant of the first type for the target logical channel, the Configured granttype1Allowed parameter is represented as true, which indicates that the target logical channel may use the Configured grant of the first type Configured by the resource configuration information, and the logical channel group where the target logical channel is located has cache data, that is, uplink data is sent on the target logical channel, it is determined that the priority of the uplink resource based on the Configured scheduled Configured grant is higher than the uplink resource scheduled by the PDCCH on the physical downlink control channel, and the uplink resource scheduling of the PDCCH may not preempt the uplink resource of the Configured grant, and the target logical channel performs uplink data transmission on the uplink resource corresponding to the Configured grant.

Optionally, with the uplink resource scheduling method according to the embodiment of the present invention, after step S210, the method further includes:

and if the configuration information identifier is used for indicating that the priority of the uplink resource based on the Configured grant is higher than that of the uplink resource scheduled by the PDCCH for the target logical channel, and the uplink resource scheduled by the PDCCH overlaps with the uplink resource of the Configured grant, the target logical channel performs uplink data transmission by using the uplink resource of the Configured grant.

According to the uplink resource scheduling method, whether the priority of the uplink resource based on the Configured scheduled configuration grant is higher than the uplink resource scheduled by the Physical Downlink Control Channel (PDCCH) is indicated through the configuration information identifier in the resource configuration information of the target logical channel Configured by the RRC, so that the rationality of uplink resource scheduling is ensured, and the problem that the uplink transmission of PDCCH scheduling is preferentially carried out to influence high-priority data transmission in services with time delay requirements is avoided.
