The access network device can include a base station, a wireless local area network (WLAN) access point (AP) or a wireless fidelity (WiFi) node, etc. Among them, the base station can be referred to as a node B (NB), an evolved node B (eNB), a next generation node B (gNB), a new radio node B (NR node B), an access point, a relay base station (RBS), a serving base station (SBS), a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a home node B (HNB), a home evolved node B, a transmit / receive point (TRP), a non-terrestrial network (NTN) device (such as a satellite or a high altitude platform station, etc.) or some other suitable term in the art, as long as the same technical effect is achieved. The base station is not limited to a specific technical term, and 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 for introduction, and the specific type of the base station is not limited.

[0096] Optionally, the core network device can also be referred to as a core network node, a core network function, or a core network network element, etc., which includes but is not limited to at least one of the following: a mobility management entity (MME), an access and mobility management function (AMF), a session management function (SMF), a user plane function (UPF), a policy control function (PCF), a policy and charging rules function (PCRF), an edge application server discovery function (EASDF), a unified data management (UDM), a unified data repository (UDR), a home subscriber server (HSS), a centralized network configuration (CNC), a network repository function (NRF), a network exposure function (NEF), a local NEF (L-NEF), a binding support function (BSF), an application function (AF), a location management function (LMF), a gateway mobile location center (GMLC), a network data analytics function (NWDAF), a non-terrestrial network (NTN) device (such as a satellite or a high altitude platform station, etc.), and the like.It should be noted that only the core network device in the NR system is taken as an example for introduction in the embodiments of the present application, and the specific type of the core network device is not limited.

[0098] For better understanding of the embodiments of the present application, the delivery of the payload in the non-access layer (Non-Access Stratum, NAS) message related to the present application is described.

[0099] Sometimes, some payload needs to be delivered in the NAS message, such as LPP message, SM message, SOR message, and the like. These payloads are generally carried in the Payload container IE of the NAS message. The following Table 1 takes the encoding of the uplink NAS transmission (UL NAS TRANSPORT) message as an example. The UL NAS TRANSPORT message includes a payload container type information element (Payload container type IE) and a payload container information element (Payload container IE) parameter.

[0100] Table 1

[0101] In detail, in the above Table 1, the Payload container type IE and the Payload container IE are mandatory parameters, wherein the Payload container type IE is used to indicate the content delivered in the Payload container, and the Payload container IE is used to encapsulate the payload. In this way, the receiver determines how to process or forward the payload according to the type of the payload in the NAS message after receiving the NAS message. For example, when the Payload container type IE indicates "N1 SM information", the Payload container IE carries a 5G SM message, and the AMF generally delivers the 5G SM message to the appropriate SMF for processing after receiving the message. For another example, when the Payload container type IE indicates "Multiple payloads", the Payload container IE carries multiple payloads.

[0102] In the related art, the payload container type IE can be represented by 4-bit information, which can be as shown in Table 2.

[0103] Table 2

[0104] Specifically, as shown in Table 2, the encoding field of the payload container type IE only has 3 bits left unused, i.e., the bit information 0000 / 1101 / 1110 is not used. If multiple new payloads need to be delivered in the payload container IE in the future, a resource shortage may occur if one bit of information is still used to identify one type of payload.

[0105] The wireless communication method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0106] FIG. 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 2, the wireless communication method 200 can include at least part of the following contents:

[0107] S210, the terminal sends a first message to the network side device; and / or, the terminal receives a second message from the network side device;

[0108] The first message includes at least one of the following:

[0109] The first information includes at least one first payload and / or at least one second payload.

[0110] The first indication information indicates a type of the payload carried in the first information.

[0111] The second indication information indicates that the type of the payload carried in the first information is an extended type.

[0112] The second message includes at least one of the following:

[0113] The second information includes at least one first payload and / or at least one second payload.

[0114] The third indication information indicates a type of the payload carried in the second information.

[0115] The fourth indication information indicates that the type of the payload carried in the second information is an extended type.

[0116] It should be understood that FIG. 2 illustrates steps or operations of the wireless communication method 200, but these steps or operations are only examples, and the present application can also perform other operations or variations of the individual operations in FIG. 2.

[0117] It should be understood that the above S210 can include that the terminal sends the first message to the network side device, and does not include that the terminal receives the second message from the network side device; or the above S210 can include that the terminal receives the second message from the network side device, and does not include that the terminal sends the first message to the network side device; or in the above S210, first, the terminal sends the first message to the network side device, and then the terminal receives the second message from the network side device; or in the above S210, first, the terminal receives the second message from the network side device, and then the terminal sends the first message to the network side device. In other words, there is no fixed order between the terminal sending the first message and the terminal receiving the second message. For example, after the terminal sends the first message to the network side device, the terminal receives the second message from the network side device. For another example, before the terminal sends the first message to the network side device, the terminal receives the second message from the network side device.

[0118] The payload described in the embodiments of the present application can also be referred to as or replaced by load, load, bearing, etc., or similar names, and the embodiments of the present application do not limit this.

[0123] In the embodiments of the present application, in the case of insufficient resources of the first message (such as a NAS message), the type of the load carried in the first information in the first message is indicated by the first indication information and / or the second indication information in the first message, in the case that the type of the load carried in the first information is an extended load type, in other words, in the case that the first information includes at least one first load or the first information includes at least one first load and at least one second load, the indication field for indicating the type of the load in the first message is extended, the first message is allowed to transmit more loads, the available resources for transmitting the load in the first message are extended, the case that the load cannot be transmitted due to insufficient indication field for indicating the type of the load is avoided, good scalability and compatibility are achieved, and the communication efficiency of the first message is improved to a certain extent.

[0124] Optionally, the type of the load carried in the second information is the same as the type of the load carried in the first information, and / or the encapsulation manner of the load carried in the second information is the same as the encapsulation manner of the load carried in the first information.

[0140] In some embodiments, the type of payload carried in the second information is an extended payload type.

[0141] Optionally, the extended payload type includes, but is not limited to, at least one of the following:

[0142] sensing payload, ambient internet of things (A-IoT) payload, task payload.

[0143] Optionally, the extension of the payload container type IE can be represented by the existing bit information of the second indication information (such as the payload container type IE), for example, the bit information 0000 / 1101 / 1110 can be used to represent the extension of the payload container type, further, the first indication information (such as the spare half octet) is used to represent the type of the specific payload, thus, since the two fields (the payload container type IE and the spare half octet) are consecutive bit information when encoding, that is, a total of 8 bit information is connected together, thus, the type of the carried payload can be represented as an extended type or directly represent a new type of payload. Specifically, the payload container type IE and the spare half octet can be as shown in Table 3, wherein, for example, the payload container type IE is represented by 1101 to represent the extended payload container type information element, the spare half octet is used by 0001 to indicate that the extended payload type is a sensing payload, the spare half octet is used by 0010 to indicate that the extended payload type is an A-IoT payload, the spare half octet is used by 0011 to indicate that the extended payload type is a task payload, and the spare half octet is used by 0100 to indicate that the extended payload type is a combined payload. Thus, when the receiver receives the bit 1 to the bit 4 of the Payload container type (for example, Table 3 uses the bit information 1101 as an example, and can also be 1110 or 0000), it can be judged that the sender has extended the payload container type information element, and further, the specific payload type is judged by the spare half octet field of the bit 5 to the bit 8.

[0144] Table 3

[0145] In some embodiments, the first indication information indicates that the type of the payload carried in the first information is the first payload type, and the first information includes one first payload.

[0146] Specifically, if the terminal needs to send a first payload, the terminal encapsulates the first payload in the first information, and indicates the type of the payload carried in the first information as the type of the first payload through the first indication information. It can be understood that the first indication information is used to indicate the type of the first payload in the case that the terminal needs to send the first payload.

[0147] In some embodiments, the first indication information indicates that the type of the payload carried in the first information is a first type, and the first information includes at least one first payload. Optionally, the first indication information can be or be indicated by a payload container type IE.

[0148] In some embodiments, if the terminal needs to send a sensor payload, the bit of the first indication information (such as the payload container type IE) can be set to 1101 to indicate that the type of the payload carried in the first information is the sensor payload, and the first information can be a payload container IE carrying a sensor payload. The same applies to the task payload or the environmental Internet of Things payload, which will not be described here.

[0149] Optionally, the first type is one of the following: additional payload, extended payload, and new payload.

[0150] In this embodiment, the first indication information indicates that the type of the payload carried in the first information is a first type, and the first information includes at least one first payload. Specifically, this embodiment introduces the first type, expands the type of the payload carried in the first information indicated by the first indication information, allows more payloads to be encapsulated in the first information, expands the available resources when the first message passing payload is transmitted, and avoids the case that the indication domain for indicating the type of the payload is insufficient to transmit the payload.

[0151] In some embodiments, the first indication information indicates that the type of the payload carried in the first information is a second type, and the first information includes at least one first payload and / or at least one second payload.

[0152] Optionally, the second type is one of the following: additional payload, extended payload, and new payload.

[0153] In the embodiment, the first indication information indicates that the type of the payload carried in the first information is the second type, and the first information includes at least one first payload and / or at least one second payload. Specifically, the embodiment introduces the second type, expands the type of the payload carried in the first information indicated by the first indication information, allows more payloads to be encapsulated in the first information, expands the available resources when the first message carries the payload, and avoids the case that the indication field for indicating the type of the payload is insufficient to carry the payload.

[0154] For example, the first indication information is a numerical field in a payload container type information element, such as 1101, and details are shown in Table 4. That is, 1101 indicates that the type of the payload carried in the first information is the first type (such as extended payload), or 1101 indicates that the type of the payload carried in the first information is the second type (such as extended payload). Alternatively, the first indication information can also be 1110 or 0000 in the payload container type information element, which is not limited in the embodiment.

[0155] Table 4

[0156] For example, the first indication information is a numerical field in a payload container type information element, such as 1101, and details are shown in Table 5. That is, 1101 indicates that the type of the payload carried in the first information is the first type (such as additional payload), or 1101 indicates that the type of the payload carried in the first information is the second type (such as additional payload). Alternatively, the first indication information can also be 1110 or 0000 in the payload container type information element, which is not limited in the embodiment.

[0157] Table 5

[0158] For example, the first indication information is a numerical field in the Payload container type information element, as shown in 1101 in Table 6, i.e., the type of the payload carried in the first information is the first type (e.g., New extended payload) indicated by 1101, or the type of the payload carried in the first information is the second type (e.g., New extended payload) indicated by 1101. Alternatively, the first indication information can also be 1110 or 0000 in the Payload container type information element, which is not limited in the embodiment.

[0159] Table 6

[0160] In some embodiments, the first indication information indicates that the type of the payload carried in the first information is a third type, and the first information includes at least one first payload and at least one second payload.

[0161] Alternatively, the third type is one of the following:

[0162] Multiple payload, combined payload.

[0163] It should be noted that the multiple payload or the combined payload means that multiple payloads of the same type or multiple payloads of different types are encapsulated together, which can be understood as the total number of payloads exceeding two. For example, when the terminal or the network side device needs to encapsulate one sensory payload and one A-IoT payload, or encapsulate one SMS payload and one SOR transparent payload, or encapsulate three task payloads (e.g., the three task payloads are sent to different destinations), or encapsulate one SMS payload and one task payload, the first indication information can be set to the third type, i.e., multiple payload or combined payload.

[0164] It should be noted that the combined payload can also be understood as encapsulating at least one first payload and at least one second payload together, which can be understood as the total number of payloads exceeding two and being a combination of the first payload and the second payload. For example, when the terminal or the network side device needs to encapsulate one SMS payload and one task payload, or encapsulate one LPP message payload and one sensory payload, or encapsulate one LCS payload, one terminal policy payload and one A-IoT payload, the first indication information can be set to the third type, i.e., combined payload.

[0165] In the embodiment, the first indication information indicates that the type of the payload carried in the first information is the third type, and the first information includes at least one first payload and at least one second payload.

[0166] Specifically, the embodiment introduces the third type, expands the type of the payload carried in the first information indicated by the first indication information, allows more payloads to be encapsulated in the first information, expands the available resources when the first message carries the payload, and avoids the case that the indication domain for indicating the type of the payload is insufficient to carry the payload.

[0167] For example, one encoding implementation of the first indication information can be as shown in Table 7. The first indication information is a numerical field in the payload container type information element (Payload container type information element), such as 1101 or 1110. Specifically, 1101 indicates that the type of the payload carried in the first information is the first type (such as Additional payload), and 1110 indicates that the type of the payload carried in the first information is the third type (such as Combined payload). Alternatively, 1101 indicates that the type of the payload carried in the first information is the second type (such as Additional payload), and 1110 indicates that the type of the payload carried in the first information is the third type (such as Combined payload).

[0168] Table 7
