Referring to fig. 2, fig. 2 is a protocol architecture for transmitting data according to an embodiment of the present disclosure.

It should be noted that, after the MAC entity receives a Medium Access Control Protocol Data Unit (MAC PDU), the MAC entity demultiplexes the MAC PDU. When detecting that the MAC PDU has an abnormal Medium Access Control Service Data Unit (MAC SDU), the whole MAC PDU packet needs to be discarded. In some specific application scenarios, when data transmission of a certain logical channel is performed, data in the MAC PDU may include configuration messages and data of the logical channel that is not established, and at this time, because the logical channel is not established yet, an identifier of the logical channel cannot be found in one or more logical channel identifiers of the logical channel that is successfully established and stored in the MAC entity, the data of the logical channel belongs to abnormal logical channel data for the MAC PDU, and the entire MAC PDU is discarded. Such an approach may reduce the utilization of the MAC PDU.

A method for providing data processing according to an embodiment of the present application is described below based on the network architecture and the device described in the foregoing, and referring to fig. 3, fig. 3 is a flowchart of a data processing method provided by an embodiment of the present application.

S101, the MAC entity receives the MAC PDU.

In this example, the MAC PDU includes one or more MAC SDUs. Referring to fig. 4, fig. 4 is a schematic structural diagram of a MAC PDU provided in an embodiment of the present application, where a MAC PDU includes a MAC header, one or more MAC SDUs, one or more MAC control elements, and possibly padding. The length of the MAC header and the length of the MAC SDU are variable.

In a possible case, the MAC entity receives a MAC PDU reported by a physical layer, where one or more MAC SDUs included in the MAC PDU may have an abnormal condition, for example, a logical channel identifier corresponding to some MAC SDUs cannot be confirmed.

S102, the MAC entity demultiplexes the MAC PDU.

In this example, demultiplexing refers to the MAC entity demultiplexing the received MAC PDU reported by the physical layer into MAC SDUs. Optionally, by demultiplexing, the MAC entity may determine the logical channel identifier corresponding to each MAC SDU. It should be noted that, through demultiplexing, the MAC entity may also determine other information included in the MAC PDU. Based on the mode, one or more MAC SDUs included in the MAC PDU can be conveniently processed subsequently.

S103, when the first MAC SDU with the abnormity exists in the MAC PDU, the MAC entity uploads the second MAC SDU except the first MAC SDU in the MAC PDU to the RLC entity.

In this example, the first MAC SDU is contained in one or more MAC SDUs. For example, the MAC PDU includes 10 MAC SDUs, and when 7 abnormal MAC SDUs are detected in the MAC PDU, the MAC entity uploads the remaining 3 MAC SDUs to the RLC entity except for the 7 abnormal MAC SDUs in the MAC PDU. Based on the mode, the MAC SDU which is judged to be non-abnormal in the abnormal MAC PDU can be uploaded to the RLC entity, and the utilization rate of the MAC PDU can be improved.

The following describes a manner of determining whether one MAC SDU is abnormal. In one possible implementation manner, the MAC entity stores one or more logical channel identifiers of the logical channels that have been successfully established, where the one or more logical channel identifiers do not include the corresponding logical channel identifier of the first MAC SDU. Note that the first MAC SDU is an abnormal MAC SDU. Wherein one logical channel corresponds to one logical channel identifier. After the logical channel is successfully established, the MAC entity stores one or more logical channel identifiers of the logical channel that has been successfully established. After the MAC entity demultiplexes the received MAC PDU, if the logical channel identifier corresponding to one MAC SDU does not belong to one or more stored logical channel identifiers, the MAC SDU is determined to be an abnormal MAC SDU. In the embodiment of the present application, in the case where the one MAC SDU is an abnormal MAC SDU, the one MAC SDU belongs to the first MAC PDU. It should be noted that the first MAC PDU may contain one or more MAC SDUs.

In one example, a MAC PDU is transmitted in logical channel 2, where the MAC PDU includes 2 logical channel identification 1 MAC SDUs, 3 logical channel identification 2 MAC SDUs, and 4 logical channel identification 3 MAC SDUs. The MAC entity stores the identifier 1 and the identifier 2 of the logical channel that has been successfully established. It can be seen that the MAC entity stores the identifier of the logical channel that has been successfully established and does not include logical channel identifier 3, so the first abnormal MAC SDU is the MAC SDUs with 4 logical channel identifiers 3.

Referring to fig. 5, fig. 5 is a flowchart of another data processing method provided in the embodiment of the present application. Step S204 to step S207 are a specific implementation manner of processing the first MAC SDU.

S201, the MAC entity receives the MAC PDU.

S202, the MAC entity demultiplexes the MAC PDU.

S203, when the first MAC SDU with the abnormality in the MAC PDU is detected, the MAC entity uploads the second MAC SDU except the first MAC SDU in the MAC PDU to the RLC entity.

The execution manner of steps S201 to S203 may refer to the execution manner described in steps S101 to S103 in the above description, and will not be described herein again.

S204, the MAC entity caches the first MAC SDU.

In this example, after detecting that the MAC PDU has an abnormal first MAC SDU, the MAC entity buffers the first MAC SDU. Based on the mode, the first MAC SDU can be further analyzed and processed conveniently.

S205, after the preset time period, the MAC entity determines whether the one or more logical channel identifiers include a corresponding logical channel identifier of the first MAC SDU. If the one or more logical channel identifiers do not include the corresponding logical channel identifier of the first MAC SDU, step S206 is performed. If one or more logical channel identifiers include the corresponding logical channel identifier of the first MAC SDU, step S207 is performed.

It should be noted that the MAC entity stores one or more logical channel identifiers of the successfully established logical channels, which are increased with the successful establishment of a new logical channel, or decreased with the release of a logical channel.

In this example, the MAC entity initially stores one or more logical channel identifiers of the successfully established logical channel that do not include the corresponding logical channel identifier of the first MAC SDU. However, within a preset time period, the MAC entity may receive other MAC PDUs, and after demultiplexing, the terminal device may establish a new logical channel according to one or more MAC SDUs uploaded by the MAC entity, where an identifier of the new logical channel may be a logical channel identifier corresponding to the first MAC SDU, and then the MAC entity may store the logical channel identifier corresponding to the first MAC SDU. Therefore, after the preset time period, the MAC entity needs to determine again whether the stored one or more logical channel identifiers of the successfully established logical channel include the corresponding logical channel identifier of the first MAC SDU. Based on the mode, the first MAC SDU is further analyzed and processed, and the utilization rate of the MAC PDU can be improved.

Optionally, the preset time period may be a time range. For example, the preset time period is one of 5 to 20 milliseconds. For example, the preset time period is 10 ms, after the MAC entity buffers the first MAC SDU, after the time period of 10 ms, the MAC entity may determine again whether one or more logical channel identifiers include the corresponding logical channel identifier of the first MAC SDU.

S206, the MAC entity discards the first MAC SDU.

In this example, after the preset time period, if the one or more logical channel identifiers do not include the corresponding logical channel identifier of the first MAC SDU, indicating that the corresponding logical channel of the first MAC SDU is still not successfully established within the preset time period, the MAC entity discards the first MAC SDU.

For example, assuming that the corresponding logical channel identifier of the first MAC PDU is 3, the MAC entity stores logical channel identifiers 1 and 2. In a preset time period, the MAC entity continues to receive other MAC PDUs, and after demultiplexing the MAC PDUs, the terminal device establishes a logical channel through one or more MAC SDUs uploaded by the MAC entity. After a preset period of time, the MAC entity stores logical channel identities that are still 1 and 2. At this time, the one or more logical channel identifications still do not contain the corresponding logical channel identification of the first MAC SDU, and thus, the MAC entity will discard the first MAC SDU.

S207, the MAC entity uploads the first MAC SDU to the RLC entity.

In this example, after the preset time period, if the one or more logical channel identifiers include the corresponding logical channel identifier of the first MAC SDU, which indicates that the corresponding logical channel of the first MAC SDU is successfully established within the preset time period, the MAC entity uploads the first MAC SDU to the RLC entity.

For example, assuming that the corresponding logical channel identifier of the first MAC PDU is 3, the MAC entity stores logical channel identifiers 1 and 2. In a preset time period, the MAC entity continues to receive other MAC PDUs, and after demultiplexing the MAC PDUs, the terminal device establishes a logical channel through one or more MAC SDUs uploaded by the MAC entity. After a preset period of time, the MAC entity stores logical channel identifications 1, 2, and 3. At this time, the one or more logical channel identifiers include a corresponding logical channel identifier of the first MAC SDU, and thus, the MAC entity uploads the first MAC SDU to the RLC entity.

In a possible implementation manner, if the first MAC SDU comprises multiple MAC SDUs, the MAC entity determines whether the multiple MAC SDUs included in the first MAC SDU are abnormal, that is, the MAC entity determines whether one or more stored logical channel identifiers of the successfully established logical channel include logical channel identifiers corresponding to the multiple MAC SDUs included in the first MAC SDU, respectively. And the MAC entity uploads the MAC SDU which is judged to be abnormal in the plurality of MAC SDUs to the RLC entity and discards the MAC SDU which is judged to be abnormal.

For example, assuming that the first MAC SDU includes 10 MAC SDUs, the MAC entity determines whether the 10 MAC SDUs included in the first MAC SDU are abnormal, that is, the MAC entity determines whether the stored one or more logical channel identifiers include logical channel identifiers corresponding to the 10 MAC SDUs included in the first MAC SDU, respectively. After the determination, 7 MAC SDUs are determined as non-abnormal, and the other 3 MAC SDUs are determined as abnormal. Therefore, the MAC entity uploads 7 MAC SDUs determined to be non-abnormal to the RLC entity and discards the other 3 MAC SDUs determined to be abnormal.

Referring to fig. 6, fig. 6 is a flowchart of another data processing method provided in the embodiment of the present application. Step S304 to step S308 are another specific implementation manner of processing the first MAC SDU.

S301, the MAC entity receives the MAC PDU.

S302, the MAC entity demultiplexes the MAC PDU.

S303, when the first MAC SDU with abnormity exists in the MAC PDU, the MAC entity uploads the second MAC SDU except the first MAC SDU in the MAC PDU to the RLC entity.

The execution manner of steps S301 to S303 can refer to the execution manner described in steps S201 to S203 in the above description, and will not be described herein again.

S304, the terminal device establishes the logical channel based on the configuration message of the logical channel which is not established.

In this example, the second MAC SDU uploaded to the RLC entity contains a configuration message of an un-established logical channel, and the terminal device will establish the logical channel based on the configuration message of the un-established logical channel. Based on the mode, the second MAC SDU uploaded to the RLC entity is further processed, and the utilization rate of the MAC PDU can be improved.

S305, the MAC entity buffers the first MAC SDU.

The execution manner of step S305 may refer to the execution manner described in step S204 in the above description, and is not described herein again.

S306, the MAC entity judges whether the first MAC SDU is abnormal or not based on the logic channel. If the first MAC SDU is determined not to be abnormal, step S307 is performed. If the first MAC SDU is determined to be abnormal, step S308 is executed.

In this example, after the logical channel is established, the MAC entity determines whether a first MAC SDU cached before is abnormal based on the logical channel, and performs corresponding processing on the first MAC SDU according to a determination result. Based on the mode, the first MAC SDU is further analyzed and processed, and the utilization rate of the MAC PDU can be improved.

In a possible implementation manner, the determining, by the MAC entity, whether the first MAC SDU is abnormal based on the logical channel includes: and the MAC entity judges whether the first MAC SDU is abnormal or not based on the channel identification of the logical channel.

Optionally, the manner of determining, by the MAC entity, whether the first MAC SDU is abnormal based on the logical channel is as follows: the MAC entity updates one or more stored logical channel identifications of the successfully established logical channels based on the logical channel identifications of the logical channels; if the logical channel identifier corresponding to the first MAC SDU belongs to the one or more logical channel identifiers, determining that the first MAC SDU is non-abnormal; and if the logical channel identifier corresponding to the first MAC SDU does not belong to the one or more logical channel identifiers, determining that the first MAC SDU is abnormal.

For example, the first MAC SDU may contain data of an unestablished logical channel. The terminal device establishes a logical channel based on a configuration message of an unestablished logical channel uploaded by the MAC entity, after the logical channel is established, the MAC entity updates one or more stored logical channel identifications of the successfully established logical channel, and further judges whether the previously cached first MAC SDU is abnormal or not based on the logical channel, namely, whether the one or more updated stored logical channel identifications of the successfully established logical channel contain the logical channel identification corresponding to the previously cached first MAC SDU or not is determined.

In other possible implementation manners, the MAC entity determines whether the first MAC SDU is abnormal based on other information of the logical channel, which is not limited in this embodiment of the present application.

S307, the MAC entity uploads the first MAC SDU to the RLC entity.

In this example, after the logical channel is established, if the first MAC SDU is determined to be non-abnormal, the MAC entity uploads the first MAC SDU to the RLC entity. Based on the mode, the first MAC SDU is further analyzed and processed, and the utilization rate of the MAC PDU can be improved.

For example, the first MAC SDU may be data of an un-established logical channel, where the logical channel identification bit of the data of the un-established logical channel is 3. The terminal equipment successfully establishes the logical channel 3 based on the configuration message of the logical channel 3 which is not established and uploaded by the MAC entity. After logical channel 3 establishment, the MAC entity updates the stored logical channel identification or identifications of the logical channels that have been successfully established. When the MAC entity determines that the first MAC SDU cached before is not abnormal based on the logical channel 3, it indicates that the logical channel identifier corresponding to the first MAC SDU exists in the one or more logical channel identifiers. Therefore, the MAC entity uploads the first MAC SDU to the RLC entity.

S308, the MAC entity discards the first MAC SDU.

In this example, after the logical channel is established, if the first MAC SDU is determined to be abnormal, the MAC entity discards the first MAC SDU. Based on the mode, the first MAC SDU is further analyzed and processed, and the utilization rate of the MAC PDU can be improved.

For example, the first MAC SDU may be data of an un-established logical channel, where the logical channel identification bit of the data of the un-established logical channel is 3. The terminal equipment successfully establishes the logical channel 4 based on the configuration message of the logical channel 4 which is uploaded by the MAC entity and is not established, and after the logical channel 4 is established, the MAC entity updates one or more stored logical channel identifications of the logical channel which is successfully established. When the MAC entity determines that the first MAC SDU cached before is abnormal based on the logical channel 4, it indicates that the logical channel identifier corresponding to the first MAC SDU does not exist in the one or more logical channel identifiers. Therefore, the MAC entity discards the first MAC SDU.

In a possible implementation manner, if the first MAC SDU contains multiple MAC SDUs, the MAC entity determines whether the multiple MAC SDUs contained in the first MAC SDU are abnormal based on the logical channel, uploads the MAC SDUs determined to be non-abnormal among the multiple MAC SDUs to the RLC entity, and discards the MAC SDUs determined to be abnormal.

For example, the terminal device successfully establishes the logical channel 4 based on the configuration message of the logical channel 4 uploaded by the MAC entity, and after the logical channel 4 is established, the MAC entity updates the stored one or more logical channel identifiers of the logical channel that has been successfully established. Assuming that the first MAC SDU includes 10 MAC SDUs, the MAC entity determines whether the 10 MAC SDUs included in the first MAC SDU are abnormal, that is, the MAC entity determines whether the updated one or more logical channel identifiers include logical channel identifiers corresponding to the 10 MAC SDUs included in the first MAC SDU, respectively. After the determination, 7 MAC SDUs are determined as non-abnormal, and the other 3 MAC SDUs are determined as abnormal.
