[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202311440117.7 filed in China on October 31, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of wireless communication technology, and specifically relates to an information processing method, a processing device, a communication device, and a readable storage medium. Background Art

[0004] In a type of data processing, data is processed at a granularity of packet sets (such as Protocol Data Unit (PDU) Sets) rather than packets. A packet set may include one or more packets. During data transmission, it may happen that some data in a packet set is successfully transmitted while other data fails to be transmitted. In some scenarios, when some packets in a PDU Set are missing, the PDU Set can still be used. For example, due to the use of technologies such as Forward Error Correction (FEC), a packet set with missing data can still be decoded and used. Therefore, there is no solution on how to determine whether a packet set is successful or failed, or how to discard packets in a packet set.

[0243] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0244] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects, for example, the first object can be one or more. In addition, "or" in this application represents at least one of the connected objects. For example, "A or B" covers three options, namely, Option 1: including A but not including B; Option 2: including B but not including A; Option 3: including both A and B. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0245] The term "indication" in this application can be either a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.

[0246] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) or other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than NR systems, such as 6th Generation (6G) communication systems.

[0247] A data packet set (eg, a PDU Set) is a collection of one or more data packets (eg, PDUs).

[0248] In one scenario, a PDU Set is considered successfully delivered only if all packets in the PDU Set are successfully delivered. This means that if even one packet fails, the terminal can discard the remaining packets. For example, if an uplink PDU Set contains 10 packets and the first four succeed but the fifth fails, the remaining five packets can be discarded.

[0249] One PDU Set success criterion is that the PDU Set is considered successful only when all data packets in the PDU Set are successfully transmitted or received.

[0250] However, in other scenarios, some data packets may be missing, but a PDU Set can still be used. For example, due to the use of technologies such as FEC, some PDU Sets may be usable if X% of the data packets are obtained (for example, the PDU Set can be decoded and used). Correspondingly, if X% of the data packets in the PDU Set are successful (the proportion of successful data packets to all data packets in the PDU Set is greater than or equal to X%, where X is an agreed value), the PDU Set can be considered successful. However, the X% caused by FEC may be the same or different for different PDU Sets.

[0251] The existing PDU Set Integrated Handling Information (PSIHI) is only sent through the control plane and can only indicate whether all PDUs of the PDU Set are needed to use the PDU set (The PDU PSIHI indicates whether all PDUs of the PDU Set are needed for the usage of the PDU Set). According to the new scenario, the PSIHI should also be updated accordingly. For example, if 80% of the data packets of the PDU Set are obtained, the PDU Set can be used. Then the packet loss operation based on the new PSIHI will also change. That is, if more than or equal to 20% of the data packets fail, the remaining data packets will be discarded. Otherwise, the data packets can still be sent. For example, an uplink PDU Set has 10 packets. If more than or equal to 3 data packets fail, the remaining data packets will be discarded.

[0252] In some PDU sets, the first packet often carries control information. If the first packet fails to be transmitted, the PDU set cannot be used (i.e., if the first packet of the PDU set is missing, the PDU set cannot be decoded). Therefore, in another scenario, if the first packet of a PDU set fails, the PDU set can be considered failed. Therefore, the PSIHI should also be updated accordingly. In this scenario, if the first packet in the PDU set fails, the remaining packets can be discarded.

[0253] Problem 1: In scenarios where different PDU Set success criteria vary, the following issues need to be addressed:

[0254] The problem is how to expand the value of PSIHI and how to guide the UE to perform packet loss based on the new PSIHI information.

[0255] In one solution, the PSIHI may be extended to indicate one of the following: the PDU Set may be used only when packets accounting for greater than or equal to X% of the PDU Set are obtained; or the PDU Set may be used only when the first packet in the PDU Set is obtained.

[0256] For the first value, when greater than or equal to (1-X%) failures occur in a PDU Set, the remaining data packets in the PDU Set may be discarded.

[0257] For the second value, when the first data packet in the PDU Set fails, the remaining data packets in the PDU Set may be discarded.

[0258] Alternatively, the Radio Access Network (RAN) can indicate to the UE one of the following:

[0259] When greater than or equal to Y% (1-X%) of data packets in a PDU Set fail, the remaining data packets in the PDU Set may be discarded.

[0260] For the second value, when the first data packet in the PDU Set fails, the remaining data packets in the PDU Set may be discarded.

[0261] In one embodiment, when it is determined that the criterion for judging the success or failure of a PDU Set is applicable to both the uplink and downlink of a data flow, the RAN instructs the user equipment (UE) to perform a packet loss operation upon obtaining the criterion for judging the success or failure of the PDU Set.

[0262] Question 2: In some scenarios, the success or failure criteria for different PDU Sets within the same data stream are consistent. In this case, these criteria for determining PDU Set success or failure can be communicated via control plane signaling. In other scenarios, the success or failure criteria for different PDU Sets within the same data stream are inconsistent. That is, the principles for determining success or failure for different PDU Sets differ. For example, for the first PDU Set, 100% reception is required for it to be considered successful. For the second PDU Set, only 85% of the packets need to be successfully transmitted for it to be considered successful. Therefore, the criteria for determining PDU Set success or failure communicated via the control plane cannot be met.

[0263] One solution is to assume that the server is aware of this situation. It can set different PDU Set success and failure criteria per PDU. The Packet Service Anchor (PSA) UPF detects this information and carries it in the GPRS Tunneling Protocol-User Plane (GTP-U) header of the packet. The RAN can use the per-PDU Set success and failure criteria to determine whether the PDU Set was delivered successfully or not, and whether to discard any remaining packets.
