[0027] To better understand the embodiments of the present application, the following three technical points will be introduced first:

[0028] 1. Introduction to Survival Time:

[0029] For services with higher reliability requirements, the sending of data packets has an expected arrival time or survival time. If the receiving end of the data does not receive the data at the expected arrival time of a specific piece of data, the application service will be in an unavailable state, and thus it will take a longer time to recover the normal application service process.

[0030] 2. Introduction to Packet Data Convergence Protocol (PDCP):

[0031] At the PDCP data sending end, for each PDCP service data unit (SDU) received from the upper layer, a discard timer (discardTimer) is started. When the timer times out, the UE discards the PDCP SDU and the corresponding PDCP PDU.

[0032] 3. Introduction to Medium Access Control (MAC)

[0033] Each transmitted data MAC protocol data unit (PDU) at the MAC layer sending end contains the MAC SDU data of one or more logical channels, and each MAC PDU is sent through a Hybrid Automatic Repeat reQuest (HARQ) process. The network side can re - transmit the MAC PDU by scheduling the re - transmission of the HARQ process.

[0034] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

However, the following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions, although these technologies can also be applied to applications other than NR system applications, such as the 6th Generation (6G) communication system. th Generation, 6G) communication system.

[0037] Figure 1The block diagram of a wireless communication system to which the embodiments of the present application can be applied is shown.

It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0038] The method for data processing provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0039] See Figure 2 , an embodiment of the present invention provides a method for data processing. The execution subject of this method can be a terminal, and the specific steps include: Step 201.

[0040] Step 201: The MAC entity of the terminal discards the first data packet, where the transmission delay of the first data packet exceeds a first predetermined duration, or the first data packet is a data packet indicated by the network side to be discarded, or the transmission delay of the data packet associated with the first data packet exceeds a second predetermined duration.

[0041] For example, if the transmission delay of data packet A exceeds a first predetermined duration, the MAC entity of the terminal discards the first data packet.

[0042] For another example, the terminal receives Downlink Control Information (DCI), and the DCI instructs the terminal to discard the first data packet, then the MAC entity of the terminal discards the first data packet.

[0043] For still another example, data packet A, data packet B, and data packet C form a data packet group. If the transmission delay of data packet B or data packet C exceeds a second predetermined duration, the MAC entity of the terminal discards data packet A.

[0044] Optionally, the first predetermined duration and / or the second predetermined duration are configured by the network-side device or agreed upon by the protocol. The first predetermined duration and the second predetermined duration may be the same or different.

[0045] In the embodiments of the present application, the MAC entity of the terminal discarding the first data packet includes any one or more of the following methods:

[0046] (1) If the media access layer protocol data unit contains the first data packet, discard the media access layer protocol data unit;

[0047] (2) If the first media access layer protocol data unit contains the first data packet, reconstruct a second media access layer protocol data unit based on the first media access layer protocol data unit, and the second media access layer protocol data unit does not include the first data packet;

[0048] (3) The MAC entity of the terminal clears a first buffer, and the first buffer is a buffer of a HARQ process containing the first data packet;

[0049] (4) The MAC entity of the terminal stops the retransmission of the HARQ process, and the HARQ process contains the first data packet.

[0050] In the embodiments of the present application, on the basis of Figure 2 After step 201, the method may further include: sending first information to the network-side device, where the first information represents the HARQ information corresponding to the first data packet.

[0051] For example, send the first information to the network-side device through uplink control information, a media access layer control unit, or a Radio Resource Control (RRC) message.

[0052] Optionally, the HARQ information includes at least one of the following: (1) a HARQ process number; (2) second information indicating whether retransmission of the HARQ process including the first data packet is required.

[0053] In an embodiment of the present application, the MAC entity of the terminal can identify the first data packet according to the identifier of the first data packet. The identifier of the first data packet may include at least one of the following: (1) a data flow identifier; (2) a data radio bearer identifier; (3) a session identifier; (4) a logical channel identifier; (5) a data packet size, and the data packet size is less than or equal to a threshold value configured by the network or agreed upon by the protocol.

[0054] For example, the identifier of the first data packet (such as a PDCP SDU) is a specified identifier by the network side or the protocol, such as a data flow identifier, a data radio bearer identifier, a session identifier, or a logical channel identifier. If the transmission delay of the first data packet with the specified identifier exceeds a first predetermined duration, or the network side instructs to discard the first data packet with the specified identifier, or the transmission delay of the data packet associated with the first data packet with the specified identifier exceeds a second predetermined duration, then the MAC entity of the terminal discards the first data packet with the specified identifier.

[0055] For another example, the MAC entity of the terminal can identify the first data packet according to the data packet size. Exemplarily, the size of the first data packet is less than the threshold value of 10 bytes (byte) configured by the network or agreed upon by the protocol. This type of data packet is identified as an unimportant data packet. That is, when the size of the first data packet is greater than or equal to 10 bytes, and the transmission delay of the first data packet exceeds a first predetermined duration, or the network side instructs to discard the first data packet with a data packet size less than or equal to 10 bytes, or the size of the first data packet is greater than or equal to 10 bytes, and the transmission delay of the data packet associated with the first data packet exceeds a second predetermined duration, then the MAC entity of the terminal discards the first data packet with a data packet size less than or equal to 10 bytes.

[0056] In an embodiment of the present application, the MAC entity of the terminal can discard a specified data packet, for example, the transmission delay of the specified data packet exceeds a predetermined duration, or the specified data packet is a data packet instructed by the network side to be discarded, or the transmission delay of the data packet associated with the specified data packet exceeds a predetermined duration, thereby saving data transmission resources.

[0057] See Figure 3 , an embodiment of the present invention provides a data processing method, and the execution subject of this method is a network-side device. The specific steps include: step 301 and step 302.

[0058] Step 301 receives first information from a terminal, where the first information represents HARQ information corresponding to a first data packet, the transmission delay of the first data packet exceeds a first predetermined duration, or the first data packet is a data packet indicated by the network side to be discarded, or the transmission delay of a data packet associated with the first data packet exceeds a second predetermined duration;

[0059] For example, the first information is received from the terminal through uplink control information, a media access control unit, or a radio resource control message.

[0060] In an embodiment of this application, the first predetermined duration and / or the second predetermined duration are configured by the network side device or agreed upon by a protocol.

[0061] Step 302: Stop the retransmission of the HARQ process corresponding to the HARQ information.

[0062] In an embodiment of this application, stopping the retransmission of the HARQ process corresponding to the HARQ information includes: (1) sending a new data packet through the HARQ process corresponding to the HARQ information; or, based on the first information, it is obtained that the data of the HARQ process corresponding to the HARQ information is successfully received by the terminal.

[0063] In an embodiment of this application, the MAC entity of the terminal can identify the first data packet according to the identifier of the first data packet. The identifier of the first data packet may include at least one of the following: (1) a data stream identifier; (2) a data radio bearer identifier; (3) a session identifier; (4) a logical channel identifier; (5) the size of the data packet, and the size of the data packet is less than or equal to a threshold value configured by the network or agreed upon by the protocol.

[0064] For example, the network side or a protocol stipulates that the identifier of the first data packet (such as a PDCP SDU) is a specified identifier, such as a data stream identifier, a data radio bearer identifier, a session identifier, or a logical channel identifier, etc. When the transmission delay of the first data packet with the specified identifier exceeds the first predetermined duration, or the first data packet with the specified identifier indicated by the network side to be discarded, or the transmission delay of a data packet associated with the first data packet with the specified identifier exceeds the second predetermined duration, the MAC entity of the terminal discards the first data packet with the specified identifier.

[0065] For another example, the MAC entity of the terminal can identify the first data packet according to the size of the data packet. Exemplarily, the size of the first data packet is less than the threshold value of 10 bytes (byte) configured by the network or agreed upon by the protocol. This type of data packet is identified as an unimportant data packet. That is, when the size of the first data packet is greater than or equal to 10 bytes, and the transmission delay of the first data packet exceeds the first predetermined duration, or the size of the first data packet indicated by the network side to be discarded is less than or equal to 10 bytes, or the size of the first data packet is greater than or equal to 10 bytes, and the transmission delay of the data packet associated with the first data packet exceeds the second predetermined duration, the MAC entity of the terminal discards the first data packet with a size less than or equal to 10 bytes.

[0066] In the embodiments of the present application, the HARQ information includes at least one of the following: (1) the HARQ process number; (2) second information, where the second information indicates whether retransmission of the HARQ process is required, and the HARQ process includes the first data packet.

[0067] In the embodiments of the present application, the MAC entity of the terminal can discard the specified data packet. For example, the transmission delay of the specified data packet exceeds the predetermined duration, or the specified data packet is the data packet indicated by the network side to be discarded, or the transmission delay of the data packet associated with the specified data packet exceeds the predetermined duration, thereby saving data transmission resources.

[0068] See Figure 4 , and the specific steps include step 401 to step 403.

[0069] Step 401: The UE, according to the network side configuration or protocol agreement, when the transmission delay of the first data packet exceeds the first predetermined duration, or when the first data packet is the data packet indicated by the network side to be discarded, or when the transmission delay of the data packet associated with the first data packet exceeds the second predetermined duration, the MAC entity of the UE discards the first data packet.

[0070] Among them, the identifier of the first data packet includes at least one of the following:

[0071] (1) Data flow identifier;

[0072] Optionally, the data flow identifier can be a Quality of Service flow, for example, QoSflow-1;

[0073] (2) Data Radio Bearer (DRB) identifier, for example, DRB-1;

[0074] (3) Session identifier, for example, PDU Session-1;

[0075] (4) Logical Channel IDentifier (LCID), for example, LCID-1.

[0076] (5) Packet size, which is less than or equal to the threshold value configured by the network or agreed upon by the protocol.

[0077] Optionally, the duration range of the predetermined duration is configured by the network or agreed upon by the protocol.

[0078] Optionally, when the transmission delay of the first packet exceeds the predetermined duration, the MAC entity of the UE determines whether to discard the first packet according to the preset discard judgment condition. If it meets the discard judgment condition, the first packet is discarded; otherwise, the first packet is not discarded.

[0079] Among them, the discard judgment condition includes any one of the following:

[0080] (1) Condition 1: If the MAC PDU only contains the first packet whose transmission delay exceeds the predetermined duration, the MAC entity of the UE discards the MAC PDU.

[0081] For example, MAC PDU-1 contains MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2), where both logical channel-1 and logical channel-2 are logical channels configured by the network side that can discard MAC data, and the transmission delays of MAC SDU-1 and MAC SDU-2 both exceed the predetermined duration, then the MAC entity of the UE discards the MAC PDU.

[0082] For example, MAC PDU-1 contains MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2), where only logical channel-1 is a logical channel configured by the network side that can discard MAC data, then the MAC entity of the UE does not discard the MAC PDU-1.

[0083] For example, MAC PDU-1 contains MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2), where both logical channel-1 and logical channel-2 are logical channels configured by the network side that can discard MAC data, and only the transmission delay of MAC SDU-1 exceeds the predetermined duration, then the MAC entity of the UE does not discard the MAC PDU.

[0084] Condition 2: If the MAC PDU contains the first packet whose transmission delay exceeds the predetermined duration, the UE reconstructs the MAC PDU and discards the MAC PDU, while the reconstructed MAC PDU does not contain the first packet whose transmission delay exceeds the predetermined duration.

[0085] For example, MAC PDU-1 contains MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2). Both logical channel-1 and logical channel-2 are logical channels configured by the network side that can discard MAC data. If only the transmission delay of MAC SDU-1 exceeds a predetermined duration, the MAC entity of the UE reconstructs this MAC PDU-1 to obtain MAC PDU-2, discards MAC PDU-1, and MAC PDU-2 does not include MAC SDU-1.

[0086] For example, MAC PDU-1 contains MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2). Only logical channel-1 is a logical channel configured by the network side that can discard MAC data. If the transmission delay of MAC SDU-1 exceeds a predetermined duration, the MAC entity of the UE reconstructs this MAC PDU-1 to obtain MAC PDU-2, and MAC PDU-2 does not include MAC SDU-1.

[0087] Among them, the MAC entity of the UE discarding the first data packet may include any one of the following:

[0088] (1) The MAC entity of the UE clears the cache of the HARQ process containing the first data packet.

[0089] For example, after the MAC entity of the UE determines to discard the MAC PDU-1 data packet and this MAC PDU-1 is cached in HARQ process-1, the UE clears the cache of HARQ process-1.

[0090] (2) The MAC entity of the UE stops the retransmission of the HARQ process containing the first data packet.

[0091] For example, after the MAC entity of the UE determines to discard the MAC PDU-1 data packet and this MAC PDU-1 is cached in HARQ process-1, if the UE receives a retransmission indication for HARQ process-1 again, the UE does not retransmit the HARQ process-1 containing MAC PDU-1.

[0092] Step 402: The UE sends first information to the network side device, and this first information indicates the HARQ information corresponding to the discarded data packet.

[0093] Among them, the HARQ information may include at least one of the following:

[0094] (1) HARQ process number, for example, HARQ process-1.

[0095] (2) Second information, which indicates whether to retransmit the discarded data packet. For example, 1 bit indicates whether it is necessary to retransmit the discarded data packet.

[0096] For example, the Physical Uplink Shared Channel (PUSCH) of the UE contains Uplink Control Information (UCI) and data information. Among them, the UCI contains 1-bit indication information. The value 1 indicated by the indication information means that the HARQ process corresponding to the PUSCH will no longer retransmit the discarded data packet.

[0097] Among them, the indication information can be sent by any one of the following methods:

[0098] (1) Sent through UCI;

[0099] (2) Sent through MAC CE (Control Element);

[0100] (3) Sent through RRC message.

[0101] Step 403: After receiving the indication information, the network side device stops the retransmission of the HARQ process.

[0102] For example, it indicates that the HARQ process sends new data, or indicates that the data of the HARQ process is successfully received.

[0103] In the embodiments of the present application, the MAC entity of the terminal can discard the specified data packet. For example, the transmission delay of the specified data packet exceeds the predetermined duration, or the specified data packet is the data packet indicated by the network side to be discarded, or the transmission delay of the data packet associated with the specified data packet exceeds the predetermined duration, thereby saving data transmission resources.

[0104] See Figure 5 , the embodiments of the present invention provide a data processing device, which is applied to a terminal. The device 500 includes:

[0111] Or,

[0112] The MAC entity of the terminal clears a first buffer, where the first buffer is a buffer of a hybrid automatic repeat request (HARQ) process that contains the first data packet;
