Abstract

This disclosure introduces an advancement to the error indication message to provide detailed information about errors in configurations that are arriving from the Layer 2 to the Layer 1. A method is disclosed, comprising: performing physical layer control (PHY) of a wireless signal at a Layer 1 (L1) software module; performing medium access control (MAC) of the wireless signal at a Layer 2 (L2) software module; providing an application programming interface between the L1 software module and the L2 software module for receiving L1 configuration messages and providing error codes to the L2 software module; receiving a L1 configuration message at a Layer 1 software module; and providing an enhanced error code progressively from a L1 software module to the Layer 2 (L2) software module.

Claims (24)

1. A method, comprising:

performing, in a wireless network including an Long Term Evolution (LTE) base station, physical layer control (PHY) of a wireless signal at a Layer 1 (L1) software module;

performing medium access control (MAC) of the wireless signal at a Layer 2 (L2) software module of the LTE base station;

providing an application programming interface between the L1 software module and the L2 software module for receiving L1 configuration messages and providing error codes to the L2 software module of the LTE base station;

receiving a L1 configuration message at the Layer 1 software module; and

providing a progressively generated enhanced error code from the L1 software module to the Layer 2 (L2) software module,

the enhanced error code based on progressive error checking of the received L1 configuration message at the L1 software module prior to installation as a configuration for the L1 software module.

2. The method of claim 1 , wherein providing the enhanced error code further comprises performing boundary range error checking of each parameter sent in the L1 configuration message against an acceptable range for the each parameter.

3. The method of claim 2 , wherein providing the enhanced error code further comprises subsequently performing error checking of a number of requested downlink (DL) or uplink (UL) protocol data units (PDUs) sent in the L1 configuration message against a supported number of DL or UL PDUs supported by the L1 software module.

4. The method of claim 3 , wherein providing the enhanced error code further comprises subsequently performing error checking of a scheduling configuration sent in the L1 configuration message against a computation capacity constraint of the L1 software module.

5. The method of claim 4 , wherein providing the enhanced error code further comprises subsequently performing error checking of each configuration instruction sent in the L1 configuration message to identify pointer violation or memory alignment issues.

6. The method of claim 5 , wherein providing the enhanced error code further comprises subsequently performing error checking of calculated parameters based on parsing parameters sent in the L1 configuration message, and of a scheduling limitation of the L1 software module.

7. The method of claim 1 , wherein providing the enhanced error code further comprises:

performing boundary range error checking of each parameter sent in the L1 configuration message against an acceptable range for the each parameter;

performing error checking of a number of requested downlink (DL) or uplink (UL) protocol data units (PDUs) sent in the L1 configuration message against a supported number of DL or UL PDUs supported by the L1 software module;

performing error checking of a scheduling configuration sent in the L1 configuration message against a computation capacity constraint of the L1 software module;

performing error checking of each configuration instruction sent in the L1 configuration message to identify pointer violation or memory alignment issues; and

performing error checking of calculated parameters based on parsing parameters sent in the L1 configuration message, and of a scheduling limitation of the L1 software module.

8. The method of claim 1 , further comprising creating the enhanced error code based on a union of multiple error checking results, thereby providing error codes reflecting a plurality of errors in the L1 configuration message.

9. The method of claim 1 , further comprising creating an error record in a database, the error record being the L1 configuration message associated with the enhanced error code.

10. The method of claim 1 , further comprising correcting a subsequent L1 configuration message based on the error record.

11. The method of claim 1 , further comprising storing a corrected L1 configuration message in association with the error record, and substituting a subsequent L1 configuration message with the corrected L1 configuration message prior to providing the corrected L1 configuration message to the L1 software module.

12. The method of claim 1 , wherein the application programming interface is a Fast Application Programming Interface (FAPI).

13. The method of claim 1 , wherein the L1 software module and the L2 software module are located at a 5G base station, and wherein receiving the L1 configuration message and providing the enhanced error code are performed at the 5G base station.
