[0038] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement.

[0042] Please refer to FIG1 , which shows a schematic diagram of a network architecture 100 provided by an embodiment of the present application. The network architecture 100 may include: a terminal device 10 , an access network device 20 , and a core network device 30 .

[0043] The terminal device 10 may refer to a UE (User Equipment), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user apparatus.

For ease of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in each cell managed by an access network device 20. In the embodiments of the present application, “terminal device” and “UE” are often used interchangeably, but those skilled in the art will understand that the two generally express the same meaning.

[0044] Access network equipment 20 is a device deployed in an access network to provide wireless communication capabilities for terminal device 10. Access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different wireless access technologies, the names of devices that provide access network equipment functions may vary. For example, in 5G NR systems, they are referred to as gNodeBs or gNBs. As communication technologies evolve, the term "access network equipment" may change. For ease of description, in the embodiments of this application, the aforementioned devices that provide wireless communication capabilities for terminal device 10 are collectively referred to as access network equipment. Optionally, a communication relationship can be established between terminal device 10 and core network equipment 30 through access network equipment 20. For example, in an LTE (Long Term Evolution) system, access network equipment 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs within EUTRAN. In a 5G NR system, access network equipment 20 may be a Radio Access Network (RAN) or one or more gNBs within the RAN. In the embodiment of the present application, unless otherwise specified, the "network device" refers to the access network device 20, such as a base station.

[0045] The core network device 30 is a device deployed in the core network. The functions of the core network device 30 are mainly to provide user connections, user management, and service bearer, and to provide an interface to the external network as a bearer network. For example, the core network devices in the 5G NR system may include devices such as the AMF (Access and Mobility Management Function) entity, the UPF (User Plane Function) entity, and the SMF (Session Management Function) entity.

[0046] In some embodiments, the access network device 20 and the core network device 30 communicate with each other via an air interface technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other via an air interface technology, such as the Uu interface.

[0047] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, subsequent evolution systems of 5G NR systems, and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, and this application does not limit this.

[0048] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0049] Before introducing the technical solutions of this application, we first introduce and explain some of the background technologies involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0050] 1. Zero-power communication network

[0051] Zero-power communication networks are a type of wireless communication technology suitable for short-distance, low-speed communications. Zero-power terminal devices primarily combine RF energy harvesting, backscattering, and low-power computing technologies to achieve the advantage of not requiring a power supply.

[0052] The core of RF energy harvesting technology is to convert RF energy into DC. RF energy can be stored in batteries or capacitors, or it can be directly used to drive logic circuits, digital chips or sensor devices after harvesting, to complete functions and applications such as modulation and transmission of backscattered signals, and collection and processing of sensor information.

[0053] The zero-power communication network is shown in Figure 2. A zero-power terminal device (Tag) 210 includes an energy harvesting module 211, a backscatter communication module 212, and a low-power computing module 213. The zero-power terminal device (Tag) 210 communicates with other terminal devices (e.g., a reader / writer) 220. Of course, the zero-power terminal device can also communicate with access network devices and core network devices, but this is only for illustrative purposes.

[0054] With the development of 5G systems, there is a growing demand for 5G systems to support network access by zero-power terminal devices. This primarily targets scenarios with the following characteristics: extreme environments unsuitable for standard terminals; extremely low power consumption and cost; and battery-free terminals.

[0055] Zero-power communication systems can be applied in scenarios such as wireless industrial sensing networks, smart agriculture, smart warehousing and logistics, and smart homes.

[0056] Based on the energy source and usage of zero-power terminal devices, zero-power terminal devices can be divided into the following types:

[0057] 1. Passive zero-power terminal equipment

[0058] Zero-power terminal devices do not require internal batteries. When they approach network equipment (such as the reader / writer of an RFID (Radio Frequency Identification) system), they are within the near-field range formed by the network equipment's antenna radiation. Therefore, the zero-power terminal device's antenna generates an induced current through electromagnetic induction. This induced current drives the low-power chip circuit of the zero-power terminal device to perform tasks such as demodulating forward link signals and modulating backward link signals. For backscatter links, zero-power terminal devices use backscattering to transmit signals.

[0059] It can be seen that the passive zero-power terminal device does not require a built-in battery to drive either the forward link or the reverse link, and is a true zero-power terminal device.

[0060] Passive zero-power terminal devices do not require batteries, and the RF circuit and baseband circuit are very simple. For example, they do not require LNA (Low Noise Amplifier), PA (Power Amplifier), crystal oscillator, ADC (Analog to Digital Converter) and other devices. Therefore, they have many advantages such as small size, light weight, very low price and long service life.

[0061] This type of terminal device also has the following characteristics: no battery; obtains energy from the surrounding environment (such as radio waves, solar energy, wind energy, mechanical kinetic energy, etc.); no USIM (Universal Subscriber Identity Module) card; and can also use the surrounding environment to store a certain amount of energy, but the energy is very small, so the functional logic supported is much less than that of ordinary terminal devices.

[0062] 2. Semi-passive zero-power terminal equipment

[0063] Semi-passive zero-power terminal devices do not have conventional batteries themselves, but instead use RF (Radio Frequency) energy harvesting modules to harvest radio wave energy and store the harvested energy in an energy storage unit (such as a capacitor). This energy storage unit then drives the low-power chip circuitry of the zero-power terminal device, enabling tasks such as demodulating forward link signals and modulating backward link signals. For backscatter links, the zero-power terminal uses backscattering to transmit signals.

[0064] It can be seen that the semi-passive zero-power terminal device does not require a built-in battery to drive either the forward link or the reverse link. Although energy stored in capacitors is used in operation, the energy comes from the radio energy collected by the energy harvesting module. Therefore, it is also a true zero-power terminal.

[0065] Semi-passive zero-power terminal equipment inherits many advantages of passive zero-power terminal equipment, so it has many advantages such as small size, light weight, very low price, and long service life.

[0066] 3. Active zero-power terminal equipment

[0067] In some scenarios, zero-power terminal devices can also be active zero-power devices, which can have built-in batteries. The battery is used to drive the low-power chip circuits of the zero-power terminal device, performing tasks such as demodulating forward link signals and modulating reverse link signals. However, for backscatter links, the zero-power terminal uses backscattering to transmit signals. Therefore, the zero-power nature of this type of terminal lies primarily in the fact that reverse link signal transmission does not require the terminal device's own power, but instead uses backscattering.

[0068] Active zero-power terminal devices have built-in batteries that power the RFID chip, increasing their read and write range and improving communication reliability. Therefore, they are suitable for scenarios with relatively high requirements for communication distance and read latency. These zero-power terminal devices can be tags or standard devices.

[0069] 2. Access Layer Protocol Stack

[0070] In the related art, the access layer protocol stack is shown in Figure 3: the user plane protocol layer includes PHY, MAC, RLC, PDCP and SDAP. The user plane upper layer data generated by the application layer is passed to PHY through SDAP, PDCP, RLC, and MAC layers, and sent by PHY. In some embodiments, above the SDAP layer and below the application layer, it may also include a UDP / TCP (User Datagram Protocol / Transmission Control Protocol) layer and an IP (Internet Protocol) layer, that is, the user plane upper layer data needs to be passed through UDP / TCP, IP, SDAP, PDCP, RLC, and MAC layers before being passed to PHY. The receiving process is received by PHY, and then passed to the application layer through MAC, RLC, PDCP, SDCP, IP, and UDP / TCP layers. User plane data transmission is carried out between the terminal device and the access network device based on the access layer protocol stack shown in Figure 3.

[0071] As shown in Figure 4, the control plane protocol layer includes RRC (Radio Resource Control). The control plane upper layer signaling generated by RRC is transmitted to PHY through the protocol stack layer by layer, and transmitted by PHY. Control plane data transmission is based on RRC between the terminal device and the access network device.

[0072] In some embodiments, the terminal device and the core network device can communicate through NAS (Non-access stratum). The control plane upper layer signaling generated by NAS is transmitted to PHY through the protocol stack layer by layer, and PHY transmits the control plane upper layer signaling to the core network device.

[0073] Of course, in the sidelink, communication between terminal devices can also be carried out through the above-mentioned access layer protocol stack.

[0074] However, in related technologies, different access layers are designed to implement complex functions. For example, the MAC is designed to perform the following functions:

[0075] Mapping between logical channels and transport channels;

[0076] Multiplex MAC Service Data Units (MAC SDUs) belonging to one or different logical channels onto a transport channel and deliver them to the physical layer's transport block (TB), or demultiplex them from a transport block.

[0077] Dispatch information report;

[0078] Error correction via HARQ (Hybrid Automatic Repeat-reQuest) (one HARQ entity per cell in the case of CA);

[0079] Priority handling between UEs with the help of dynamic scheduling;

[0080] Prioritize logical channels within a UE with the help of logical channel prioritization;

[0081] Prioritization between overlapping resources of a UE;

[0082] ·filling.

[0083] The access layer protocol stack is too complex, which causes the communication process based on the access layer protocol stack to be correspondingly highly complex.

[0084] Please refer to Figure 5, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The method is executed by a terminal device and may include the following step 510.

[0085] Step 510: Transmit user plane upper layer data directly carried by the physical layer.

[0086] In some embodiments, transmitting the user plane upper layer data directly carried by the physical layer refers to sending or receiving the user plane upper layer data directly carried by the physical layer. In this embodiment, sending the user plane upper layer data directly carried by the physical layer is used as an example for illustrative description.

[0087] In some embodiments, the above-mentioned transmission of user plane upper layer data directly carried by the physical layer can be the transmission of user plane data between terminal devices, or the transmission of user plane data between terminal devices and network devices. This application does not limit this.

[0088] In some embodiments, the terminal device may be a zero-power consumption terminal device.

[0089] User plane upper layer data refers to user plane data generated by the protocol layer above the physical layer.

[0090] In some embodiments, the user plane upper layer data refers to service data of the user plane, such as service data of a voice service. In the embodiments of the present application, the specific service type of the user plane upper layer data is not limited.

[0091] In some embodiments, the upper layer data of the user plane may be referred to as data, or as data bearer, or as user plane information, or other names, which are not limited in this application.

[0092] In some embodiments, the data bearer refers to a DRB (Data Radio Bearer).

[0093] Exemplarily, user plane upper layer data is transmitted through the protocol stack shown in Figure 6, and the user plane upper layer data is directly carried by the physical layer, that is, UE1 sends user plane upper layer data to UE2 through the physical layer, and UE2 receives and parses the user plane upper layer data from UE1 through the physical layer.

[0094] In some embodiments, the user plane upper layer data includes at least one of the following: IP-based upper layer data, Ethernet-based upper layer data, unstructured-based upper layer data, and application layer data.

[0095] In the TCP / IP protocol, packets that transmit data using the IP protocol are called IP datagrams. Each datagram contains the content specified by the IP protocol. These contents specified by the IP protocol are called IP datagrams or IP packets. An IP datagram consists of two parts: a header (called a packet header) and data. The first part of the header is a fixed length of 20 bytes and is required for all IP packets. Following the fixed part of the header are several optional fields of variable length. Every IP datagram begins with an IP header. The source device constructs this IP header, and the destination device processes the data using the information encapsulated in the IP header. The IP header contains a large amount of information, such as the source IP address, destination IP address, packet length, and IP version number. Each piece of information is called a field.

[0096] Ethernet is a baseband local area network technology. Ethernet communication is a communication method that uses coaxial cable as the network medium and adopts carrier multiple access and collision detection mechanism. The data transmission rate reaches 1Gbit / s, which can meet the needs of non-continuous network data transmission.

[0097] The application layer is used to provide a network interface to applications and provide services directly to users. The application layer data is the application data.

[0098] In some embodiments, the user plane upper layer data is generated by a protocol layer.

[0099] In some embodiments, a first protocol layer for generating user plane upper layer data is located above the physical layer.

[0100] In some embodiments, user plane upper layer data is sent directly to the physical layer via the first protocol layer, and user plane upper layer data received from the first protocol layer is sent via the physical layer. That is, there are no other protocol layers between the first protocol layer and the physical layer, and user plane upper layer data generated by the first protocol layer is sent directly to the physical layer without being transferred or forwarded by other protocol layers.

[0101] In some embodiments, the user plane upper layer data includes application layer data, and the first protocol layer includes the application layer, that is, the application layer is located above the physical layer, and the application layer data is directly sent to the physical layer through the application layer, and the application layer data is received from the application layer through the physical layer. Exemplarily, as shown in Figure 7, the protocol stack includes the application layer and the physical layer, and the application layer generates application layer data, sends the application layer data directly to the physical layer, and sends the application layer data received from the application layer through the physical layer.

[0102] In some embodiments, the user plane upper layer data includes IP-based upper layer data, and the first protocol layer includes the IP layer, that is, the IP layer is located above the physical layer, and the IP-based upper layer data is sent directly to the physical layer through the IP layer, and the IP-based upper layer data received from the IP layer is sent through the physical layer.

[0103] Exemplarily, as shown in FIG8 , the protocol stack includes an IP layer and a physical layer. The IP layer generates IP-based upper layer data, the IP layer sends IP-based upper layer data directly to the physical layer, and sends IP-based upper layer data received from the IP layer through the physical layer.

[0104] Exemplarily, as shown in FIG8 , the protocol stack includes an application layer, a UDP / TCP layer, an IP layer, and a physical layer. The application layer generates user-plane upper-layer data, sends the user-plane upper-layer data to the IP layer through the UDP / TCP layer, obtains IP-based upper-layer data after processing by the IP layer, and the IP layer sends the IP-based upper-layer data to the physical layer, which sends the IP-based upper-layer data received from the IP layer through the physical layer.

[0105] In some embodiments, the user plane upper layer data includes Ethernet-based upper layer data, and the first protocol layer includes the Ethernet layer (or called the 802.1Q layer), that is, the Ethernet layer is located above the physical layer, and the Ethernet-based upper layer data is sent directly to the physical layer through the Ethernet layer, and the Ethernet-based upper layer data received from the Ethernet layer is sent through the physical layer.

[0106] Exemplarily, as shown in FIG9 , the protocol stack includes an Ethernet layer and a physical layer. The Ethernet layer generates Ethernet-based upper layer data, which the Ethernet layer sends directly to the physical layer. The Ethernet-based upper layer data is sent through the physical layer to the Ethernet-based upper layer data received from the Ethernet layer.

[0107] Exemplarily, as shown in FIG9 , the protocol stack includes an IP layer, an Ethernet layer, and a physical layer. The IP layer generates user-plane upper-layer data and sends the user-plane upper-layer data to the Ethernet layer. The Ethernet layer processes the obtained Ethernet-based upper-layer data. The Ethernet layer sends the Ethernet-based upper-layer data to the physical layer, and sends the Ethernet-based upper-layer data received from the Ethernet layer through the physical layer.

[0108] For example, as shown in Figure 9, the protocol stack includes the application layer, UDP / TCP layer, IP layer, Ethernet layer, and physical layer. The application layer generates user plane upper layer data, which is sent to the Ethernet layer via the UDP / TCP layer and IP layer. The Ethernet layer processes the data to obtain Ethernet-based upper layer data. The Ethernet layer sends the Ethernet-based upper layer data to the physical layer, which then sends the Ethernet-based upper layer data received from the Ethernet layer via the physical layer.

[0109] In some embodiments, the user plane upper layer data includes unstructured upper layer data, and the protocol stack includes an unstructured layer and a physical layer. As shown in Figure 10, the protocol stack includes an unstructured layer and a physical layer. The unstructured layer generates unstructured upper layer data and sends the unstructured upper layer data to the physical layer, and the unstructured upper layer data is sent through the physical layer.

[0110] In some embodiments, the user plane upper layer data may further include control information. The control information refers to control information generated by the user plane protocol layer located above the physical layer, such as control information generated by the IP layer.

[0111] In some embodiments, the method further includes step 520, sending indication information through a physical layer control channel, where the indication information is used to indicate information related to the transmission.

[0112] The physical layer control channel may include at least one of the following: PSCCH (Physical Sidelink Control Channel), PUCCH (Physical Uplink Control Channel), and PDCCH (Physical Downlink Control Channel).

[0113] In some embodiments, the indication information is used to indicate at least one of the following information:

[0114] Transmission carries data;

[0115] The transmission carries padding bits.

[0116] The transmission carries data and padding bits;

[0117] The length of the data carried by the transmission;

[0118] The length of the padding bits carried in the transport;

[0119] The length of the data and padding bits carried by the transmission;

[0120] The ratio of the length of the data carried by the transmission to the length of the padding bits.

[0121] The user plane upper layer data may include at least one of data and padding bits, that is, the user plane upper layer data may include data, padding bits, or both data and padding bits.

[0122] Exemplarily, the indication information is used to indicate the length of the data carried by the transmission, that is, the indication information is used to indicate the number of bits occupied by the data carried by the transmission.

[0123] Exemplarily, the indication information is used to indicate the length of the padding bits of the transmission bearer, that is, the indication information is used to indicate the number of bits occupied by the padding bits of the transmission bearer.

[0124] Exemplarily, the indication information is used to indicate the length of the data carried by the transmission and the length of the padding bits, that is, the indication information is used to indicate the number of bits occupied by the data carried by the transmission and the number of bits occupied by the padding bits.

[0125] Exemplarily, the indication information is used to indicate the length ratio of the data carried by the transmission and the padding bits, that is, the indication information is used to indicate the ratio between the number of bits occupied by the data carried by the transmission and the number of bits occupied by the padding bits. For example, if the number of bits occupied by the data is 5 bits and the number of bits occupied by the padding bits is 3 bits, then the indication information is used to indicate that the length ratio of the data carried by the transmission and the padding bits is 5:3.

[0126] The technical solution provided by the embodiment of the present application directly carries the user plane upper layer data through the physical layer and transmits the user plane upper layer data. The physical layer directly obtains the user plane upper layer data to be transmitted from the protocol layer that generates the user plane upper layer data, without the need to pass through the PDCP, RLC, and MAC layers. This reduces the complexity of the protocol stack, simplifies the complexity of terminal device transmission of data, and helps to reduce the power consumption of the terminal device during transmission.

[0127] In zero-power terminal devices, since zero-power terminal devices cannot support complex protocol stacks and complex communication processes, the technical solution provided by the embodiment of the present application reduces the complexity of the protocol stack, simplifies the transmission complexity, and can be more suitable for zero-power terminal devices.

[0128] Please refer to Figure 11, which shows a flowchart of a wireless communication method provided by another embodiment of the present application. The method is executed by a terminal device and may include at least one of the following steps 1110 to 1120.

[0129] Step 1110: Transmit user plane upper layer data directly carried by the physical layer.

[0130] Step 1120: Transmit the control plane upper layer signaling directly carried by the physical layer.

[0131] In some embodiments, the above-mentioned transmission of the control plane upper layer signaling directly carried by the physical layer includes sending or receiving the control plane upper layer signaling directly carried by the physical layer.

[0132] In some embodiments, control plane upper layer signaling refers to control signaling generated by the protocol layer above the physical layer. For example, signaling that controls call flow establishment, maintenance, and release. In the embodiments of the present application, the specific functions and content of the control plane upper layer signaling are not limited.

[0133] In some embodiments, the control plane upper layer signaling includes at least one of the following: RRC layer signaling, non-access layer signaling.

[0134] RRC layer signaling refers to signaling from the RRC layer, and non-access layer signaling refers to signaling from the NAS.

[0135] In some embodiments, a second protocol layer for generating control plane upper layer signaling is located above the physical layer.

[0136] In some embodiments, the control plane upper layer signaling is directly sent to the physical layer through the second protocol layer; and the control plane upper layer signaling received from the second protocol layer is sent through the physical layer.

[0137] In some embodiments, the control plane upper layer signaling includes RRC layer signaling, that is, the second protocol layer includes the RRC layer, the RRC layer is located above the physical layer, the RRC layer signaling is directly sent to the physical layer through the RRC layer, and the RRC signaling received from the RRC layer is sent through the physical layer. Exemplarily, as shown in Figure 12, the protocol stack includes the RRC layer and the physical layer, the RRC layer directly sends the RRC layer signaling to the physical layer, and the RRC layer signaling received from the RRC layer is sent through the physical layer.

[0138] In some embodiments, in uplink communication or downlink communication, the control plane upper layer signaling includes non-access layer signaling, that is, the second protocol layer includes NAS, the NAS is located above the physical layer, the non-access layer signaling is sent to the RRC layer through the NAS, the non-access layer signaling is directly sent to the physical layer through the RRC layer, and the non-access layer signaling received from the RRC layer is sent through the physical layer.

[0139] Exemplarily, as shown in FIG13 , the protocol stack includes NAS, RRC layer and physical layer. NAS sends non-access stratum signaling to the RRC layer. The RRC layer directly sends non-access stratum signaling to the physical layer, and sends non-access stratum signaling received from the RRC layer through the physical layer.

[0140] In some embodiments, in sidelink communications, control plane upper layer signaling may also include sidelink control signaling, such as PC5-S (ProSe Communication 5-Signal, ProSe Communication 5 Interface Signaling). The sidelink control protocol layer (such as the PC5-S layer) generates sidelink control signaling and sends the sidelink control signaling directly to the physical layer, which in turn sends the sidelink control signaling from the sidelink control protocol layer via the physical layer. Sidelink control signaling refers to control signaling related to sidelink communications generated by the control plane protocol layer located above the physical layer.

[0141] 14 , the protocol stack includes a PC5-S layer and a physical layer. The PC5-S layer generates PC5-S signaling and sends the PC5-S signaling directly to the physical layer, which then sends the PC5-S signaling received from the PC5-S layer through the physical layer.

[0142] In some embodiments, the transmitted user plane upper layer data and control plane upper layer signaling can be combined arbitrarily, and during transmission, the protocol stack only needs to include a first protocol layer for generating user plane upper layer data carried by the physical layer, and a second protocol layer for generating control plane upper layer signaling carried by the physical layer. The protocol layer corresponding to the user plane upper layer data not carried by the physical layer and the protocol layer corresponding to the control plane upper layer signaling not carried by the physical layer may not be called in the communication process.

[0143] Exemplarily, the user plane upper layer data carried by the physical layer includes application layer data, and the control plane upper layer signaling carried by the physical layer includes RRC layer signaling, then the protocol stack includes the RRC layer, application layer and physical layer, without calling the IP layer, Ethernet layer and NAS.

[0144] In some embodiments, the second protocol layer used to generate the upper layer signaling of the control plane is a protocol layer for the interface between terminals, or a protocol layer for the interface between the terminal and the network.

[0145] Exemplarily, the RRC layer may be an RRC layer for an interface between terminals, or an RRC layer for an interface between a terminal and a network.

[0146] In some embodiments, the RRC layer can be the RRC layer between the zero-power terminal device and the read-write device, such as the RRC layer between the tag and the reader, or it can be the RRC layer between the network device and the zero-power terminal device, such as the RRC layer between the network device and the tag.

[0147] Exemplarily, the NAS may be a NAS for an interface between terminals, such as PC5-S, or a NAS for an interface between a terminal and a network.

[0148] In some embodiments, NAS can be NAS between a zero-power terminal device and a read-write device, such as NAS between a tag and a reader, or NAS between a network device and a zero-power terminal device, such as NAS between a network device and a tag.

A transport bearer may include user plane upper layer data and control plane upper layer signaling, i.e., a transport bearer may include data, signaling, padding bits, signaling and padding bits, data and padding bits, or data, signaling, and padding bits.

[0169] Exemplarily, the indication information is used to indicate the length of the padding bits of the transmission bearer, that is, the indication information is used to indicate the number of bits occupied by the padding bits of the transmission bearer.

[0178] The technical solution provided by the embodiment of the present application directly carries the user plane upper layer data and the control plane upper layer signaling through the physical layer, and transmits the user plane upper layer data and the control plane upper layer signaling. The physical layer directly obtains the user plane upper layer data to be transmitted from the protocol layer that generates the user plane upper layer data, and obtains the control plane upper layer signaling to be transmitted from the protocol layer that generates the control plane upper layer signaling. There is no need to pass through the PDCP, RLC, and MAC layers, which reduces the complexity of the protocol stack, simplifies the transmission processing process, and further reduces the power consumption of the device.

[0179] The above embodiments are only illustrative of the sending process, and the technical solution provided in this application can also be applied to the receiving process.

[0180] In some embodiments, the above method can be applied in the communication process between terminal devices.

[0181] For example, as shown in FIG15 , the communication process between a zero-power terminal device Tag and a reader is taken as an example.

[0182] For user-side upper layer data:

[0183] On the tag side, the physical layer receives user plane upper layer data from the first protocol layer and sends the user plane upper layer data to the reader through the physical layer. For example, the physical layer receives application layer data from the application layer and sends the application layer data to the reader through the physical layer.

[0184] On the reader side, the physical layer receives user plane upper layer data from the tag and sends the user plane upper layer data to the first protocol layer through the physical layer. For example, the physical layer receives application layer data from the tag and sends the application layer data to the application layer through the physical layer.

[0185] For control plane upper layer signaling:

[0186] On the tag side, the physical layer receives the control plane upper layer signaling from the second protocol layer, and sends the control plane upper layer signaling to the reader through the physical layer. For example, the physical layer receives the RRC layer signaling from the RRC layer, and sends the RRC layer signaling to the reader through the physical layer.

[0187] On the reader / writer side, the physical layer receives the control plane upper layer signaling from the tag, and sends the control plane upper layer signaling to the second protocol layer through the physical layer. For example, the physical layer receives the RRC layer signaling from the tag, and sends the RRC layer signaling to the RRC layer through the physical layer.

[0188] In some embodiments, the above method can be applied in the communication process between the terminal device and the network device. The terminal device and the network device can communicate directly or through a relay device. This application does not limit this.

[0189] For example, as shown in FIG16 , the communication process between a zero-power terminal device Tag and a network device through a relay device reader is taken as an example.

[0190] For user-side upper layer data:

[0191] On the tag side, the physical layer receives user plane upper layer data from the first protocol layer, and sends user plane upper layer data (Tag) to the reader through the physical layer. For example, the physical layer receives application layer data from the application layer, and sends application layer data to the reader through the physical layer.

[0192] On the reader / writer side, the physical layer receives the user plane upper layer data (Tag) from the Tag, and sends the user plane upper layer data (Tag) to the first protocol layer through the physical layer. For example, the physical layer receives the application layer data from the Tag, and sends the application layer data to the application layer through the physical layer.

[0193] The physical layer can send user-plane upper layer data (Reader) to an access network device (e.g., a gNB), and the application layer can send application-layer data to an application server (APP Server). For example, the physical layer sends user-plane upper layer data to the gNB. The gNB's physical layer receives the user-plane upper layer data and forwards it to the application server, which decodes the user-plane upper layer data.

[0194] On the access network device side, the physical layer receives user-side upper layer data from the reader / writer (Reader).

[0195] Application server side: receives application layer data from the reader.

[0196] For control plane upper layer signaling:

[0197] On the tag side, the physical layer receives the control plane upper layer signaling (Tag) from the second protocol layer, and sends the control plane upper layer signaling (Tag) to the reader through the physical layer. For example, the physical layer receives the RRC layer signaling from the RRC layer, and sends the RRC layer signaling to the reader through the physical layer.

[0198] On the reader / writer side, the physical layer receives the control plane upper layer signaling (Tag) from the Tag, and sends the control plane upper layer signaling (Tag) to the second protocol layer through the physical layer. For example, the physical layer receives the RRC layer signaling from the Tag, and sends the RRC layer signaling to the RRC layer through the physical layer.

[0199] The physical layer can send control plane upper layer signaling (Reader) to the access network device, the RRC layer can send RRC signaling to the access network device, and the NAS layer can send non-access layer signaling to the core network device (AMF). For example, the physical layer sends RRC signaling to the access network device, and the physical layer of the access network device receives the RRC signaling. For example, the physical layer sends NAS signaling to the access network device, and the physical layer of the access network device receives the NAS signaling and forwards it to the core network device, which decodes the NAS signaling.

[0200] Core network equipment side: NAS receives non-access stratum signaling from the reader / writer.

[0201] Access network equipment side: The physical layer receives control plane upper layer signaling from the reader (Reader), and the RRC layer receives RRC signaling from the reader.
