Abstract

Disclosed are a scheduling request transmission control method and a related product. In the method, a terminal acquires reference information about a first parameter needing to be indicated to a network side device, wherein the first parameter is a parameter associated with cached data to be transmitted of the terminal. The terminal queries a pre-set mapping relationship between information about the first parameter and information about a second parameter of a physical uplink control channel (PUCCH) resource, and acquires reference information, corresponding to the reference information about the first parameter, about the second parameter of the PUCCH resource, wherein the second parameter is a parameter associated with the PUCCH resource for transmitting a scheduling request (SR). The terminal transmits the SR for scheduling the cached data on the PUCCH resource determined by means of the reference information about the second parameter.

Claims

acquiring, by a terminal, reference information of a first parameter required to be indicated to a network-side device, the first parameter being a parameter associated with cached data to be transmitted of the terminal, the reference information of the first parameter being used for the network-side device to determine a licensed resource, the licensed resource being used to transmit the cached data;

querying, by the terminal, a preset mapping relationship between information of a first parameter and information of a second parameter of a Physical Uplink Control Channel (PUCCH) resource to acquire reference information, corresponding to the reference information of the first parameter, of the second parameter of the PUCCH resource, the second parameter being a parameter associated with the PUCCH resource used to transmit an SR; and

transmitting, by the terminal, the SR used to schedule the cached data, on the PUCCH resource determined by the reference information of the second parameter.

2. The method of claim 1, before acquiring, by the terminal, the reference information of the first parameter required to be indicated to the network-side device, further comprising:

acquiring, by the terminal, the cached data.

3. The method of claim 1, wherein acquiring, by the terminal, the reference information of the first parameter required to be indicated to the network-side device comprises:

responsive to detecting that no Uplink Shared Channel (UL-SCH) resource is obtained to transmit the cached data, acquiring, by the terminal, the reference information of the first parameter required to be indicated to the network-side device.

4. The method of claim 1, wherein the cached data comprises at least one of:

data cached in a Radio Link Control (RLC) layer of the terminal or data cached in a Packet Data Convergence Protocol (PDCP) layer of the terminal.

5. The method of claim 1, wherein the parameter associated with the cached data to be transmitted of the terminal comprises any one of:

a Physical (PHY)-layer parameter numerology of the licensed resource used to transmit the cached data, a Transmission Time Interval (TTI) duration of the licensed resource used to transmit the cached data or a data size of the cached data; and

the second parameter comprises at least one of;

a resource type of the PUCCH resource, a resource block identifier of the PUCCH resource or a total number of repeated SR transmission times on the PUCCH resource.

6. The method of claim 1, wherein the PUCCH resource comprises at least one of:

a short-duration PUCCH resource or a long-duration PUCCH resource.

7. A terminal, comprising a processor and a transceiver, wherein p1 the transceiver is configured to acquire reference information of a first parameter required to be indicated to a network-side device, the first parameter being a parameter associated with cached data to be transmitted of the terminal, the reference information of the first parameter being used for the network-side device to determine a licensed resource and the licensed resource being used to transmit the cached data;

the processor is configured to query a preset mapping relationship between information of a first parameter and information of a second parameter of a Physical Uplink Control Channel (PUCCH) resource to acquire reference information, corresponding to the reference information of the first parameter, of the second parameter of the PUCCH resource, the second parameter being a parameter associated with the PUCCH resource used to transmit a Scheduling Request (SR); and

the transceiver is configured to transmit, through the communication unit, the SR used to schedule the cached data, on the PUCCH resource determined by the reference information of the second parameter.

8. The terminal of claim 7, wherein the transceiver is further configured to, before acquiring, by the terminal, the reference information of the first parameter required to be indicated to the network-side device, acquire the cached data.

9. The terminal of claim 7, wherein the transceiver is configured to:

responsive to detecting that no Uplink Shared Channel (UL-SCH) resource is obtained to transmit the cached data, acquire the reference information of the first parameter required to be indicated to the network-side device.

10. The terminal of claim 7, wherein the cached data comprises at least one of:

data cached in a Radio Link Control (RLC) layer of the terminal or data cached in a Packet Data Convergence Protocol (PDCP) layer of the terminal.
