Description

Wireless communication method, terminal device and network device Technical Field

[0002] To ensure the harmonious coexistence of various communication systems using unlicensed spectrum (also known as unlicensed spectrum or shared spectrum) for wireless communications, some countries or regions have established regulatory requirements for the use of unlicensed spectrum. For example, communication devices adhere to the Listen Before Talk (LBT) principle, meaning that before transmitting on a channel in unlicensed spectrum, they must first sense the channel. Only when the sensed channel indicates that the channel is idle can the device transmit. If the sensed channel indicates that the channel is busy, the device cannot transmit.

[0003] In some scenarios, terminal devices can use resources on the unlicensed spectrum to transmit side services. LBT needs to be performed before transmitting the side services. When there are services on the licensed spectrum and side services on the unlicensed spectrum at the same time, how to transmit the services is an urgent problem that needs to be solved.

A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0042] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0048] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0049] Figure 1 is a schematic diagram of a communication system applicable to embodiments of the present application. Transmission resources for vehicle-mounted terminals (vehicle-mounted terminal 121 and vehicle-mounted terminal 122) are allocated by base station 110. The vehicle-mounted terminals transmit data on the sidelink based on the resources allocated by base station 110. Specifically, base station 110 can allocate resources for a single transmission to a terminal, or it can allocate resources for semi-static transmission to the terminal.

[0050] Figure 2 is a schematic diagram of another communication system applicable to an embodiment of the present application. Vehicle-mounted terminals (vehicle-mounted terminal 131 and vehicle-mounted terminal 132) autonomously select transmission resources on the sidelink for data transmission. Alternatively, the vehicle-mounted terminals can select transmission resources randomly or through interception.

[0051] It should be noted that device-to-device communication is a sidelink (SL) transmission technology based on device-to-device (D2D). Unlike traditional cellular systems, where communication data is received or sent via base stations, the connected vehicle system uses direct device-to-device communication, resulting in higher spectrum efficiency and lower transmission latency. 3GPP defines two transmission modes: Mode A (sidelink resource allocation mode A) and Mode B (sidelink resource allocation mode B).

[0052] Mode A: The terminal's transmission resources are allocated by the base station, and the terminal sends data on the sidelink based on the resources allocated by the base station. The base station can allocate resources for a single transmission or for semi-static transmission.

[0053] Mode B: The terminal selects a resource in the resource pool for data transmission.

[0054] Proximity-based services (ProSe) involve device-to-device communication, primarily for public safety services. In ProSe, by configuring resource pools in the time domain (for example, discontinuous resource pools), the UE can transmit and receive data discontinuously on the sidelink, thereby saving power.

[0055] The IoV system primarily focuses on vehicle-to-vehicle communication scenarios, primarily targeting relatively high-speed vehicle-to-vehicle and vehicle-to-pedestrian communications. In V2X, power efficiency is less of a concern due to the continuous power supply provided by the onboard system, while data transmission latency is the primary concern. Therefore, the system design requires continuous transmission and reception by terminal devices.

[0056] Wearable device (FeD2D) scenario, which studies the scenario where wearable devices access the network through mobile phones, is mainly aimed at scenarios with low mobile speed and low power access.

[0057] In FeD2D, a base station can configure the discontinuous reception (DRX) parameters of a remote terminal through a relay terminal.

[0058] In some scenarios, a multi-carrier mechanism is introduced, which is mainly reflected in that the UE can support packet segmentation, transmit data packets through multiple carriers to improve data transmission rate; packet replication, copy an identical data packet twice and send it through two carriers to improve transmission reliability; and multi-carrier reception enhancement at the receiving end. Specifically, for packet replication: sidelink communication supports sidelink packet replication, and is executed at the Packet Data Convergence Protocol (PDCP) layer of the UE. For sidelink packet replication for transmission, the PDCP protocol data unit (PDU) is replicated at the PDCP entity. The replicated PDCP PDU of the same PDCP entity is submitted to two different Radio Link Control (RLC) entities and associated with two different sidelink logical channels respectively. The replicated PDCP PDU of the same PDCP entity is only allowed to be transmitted on different sidelink carriers.

[0059] New Radio-Vehicle to Everything (NR-V2X) supports autonomous driving, which places higher requirements on data exchange between vehicles, such as higher throughput, lower latency, higher reliability, wider coverage, and more flexible resource allocation.

[0060] In the LTE-V2X system, broadcast transmission is supported, and in the NR-V2X system, unicast and multicast transmission modes are introduced.

[0061] Similar to the LTE V2X system, the NR V2X system can also define the two resource grant modes mentioned above, Mode A and Mode B. Resource acquisition is indicated by sidelink grants, that is, the sidelink grants indicate the time-frequency location of the corresponding Physical Sidelink Control Channel (PSCCH) and Physical Sidelink Shared Channel (PSSCH) resources.

[0062] In addition to the feedback-free, UE-initiated Hybrid Automatic Repeat reQuest (HARQ) retransmission, feedback-based HARQ retransmission is introduced in NR V2X, which is not limited to unicast communication but also includes multicast communication.

[0063] In NR V2X, since the on-board system has continuous power supply, power efficiency is not the main issue, but the delay of data transmission is the main issue. Therefore, the system design requires the terminal equipment to perform continuous transmission and reception.

[0064] In some scenarios, a Layer 2 UE-to-Network (UE-to-Network) relay UE is introduced to directly connect to the network. Specifically, the remote terminal connects to the access network (e.g., gNB) and the core network (CN) (e.g., 5GC) through the UE-to-Network relay UE.

[0065] Figure 3 shows a schematic diagram of the 5G system's transport protocol stack, specifically involving the remote UE, Layer 2 UE-to-Network relay UE, gNB, and 5GC. As shown in Figure 3, the remote UE may include the following layers: Internet Protocol (IP), Uu-Service Data Adaptation Protocol (SDAP), Uu-Packet Data Convergence Protocol (PDCP), PC5-Radio Link Control (RLC), PC5-Media Access Control (MAC), and PC5-Physics (PHY). The UE-to-Network relay UE may include the following layers: Adaptation (ADAPT), PC5-RLC, PC5-MAC, PC5-PHY, Uu-RLC, Uu-MAC, and Uu-PHY. The gNB may include the following layers: Uu-SDAP, Uu-PDCP, ADAPT, Uu-RLC, Uu-MAC, Uu-PHY, and the N3 protocol stack. 5GC may include the following layers: IP, N3 protocol stack.

[0066] As shown in Figure 3, the relay UE adaptation layer (ADAPT) is implemented above the control plane and user plane RLC layers of the Uu interface between the relay UE and the gNB. Uu-SDAP, Uu-PDCP, and Radio Resource Control (RRC) terminate between the remote UE and the gNB, while RLC, MAC, and PHY terminate in every link (including the link between the remote UE and the relay UE and the link between the relay UE and the gNB).

[0067] In some embodiments, the link between the relay UE and the network can be called a Uu link, a Uu path, the direct link between the remote UE and the network can also be called a Uu link, a Uu path, and the link between the remote UE and the relay UE can be called a PC5 link, a PC5 path.

[0068] For the uplink of L2 UE-to-Network relay UE:

[0069] The adaptation layer of the relay UE supports uplink bearer mapping between access PC5 RLC channels for transmission on the Uu path between the relay UE and the network and for accessing outbound Uu channels. For uplink relay services, different end-to-end bearers (e.g., signaling radio bearers (SRBs) and data radio bearers (DRBs)) for the same remote UE and / or different remote UEs can be mapped N:1 and data multiplexed on a single Uu RLC channel.

[0070] The adaptation layer of the relay UE includes the identification information of the remote terminal of the uplink service to be relayed and the identification information of the radio bearer of the remote terminal, so that the gNB can associate the received data packets of the specific Packet Data Convergence Protocol (PDCP) entity associated with the radio bearer of the remote terminal.

[0071] For the downlink of L2 UE-to-Network relay UE:

[0072] The adaptation layer of the relay UE may be configured to support downlink bearer mapping at the gNB to map the end-to-end radio bearers (e.g., SRBs, DRBs) of the remote terminal to Uu RLC channels over the Uu path between the relay UE and the network. The adaptation layer of the relay UE may be configured to support downlink N:1 bearer mapping and data multiplexing between multiple end-to-end radio bearers (e.g., SRBs, DRBs) of the remote UE and / or different remote UEs and Uu RLC channels over the Uu path between the relay UE and the network.

[0073] The relay UE's adaptation layer includes the remote terminal's identification information for the downlink service to be relayed. The remote terminal's radio bearer identification information and the remote terminal's identification information must be placed in the relay UE's adaptation layer by the gNB so that the relay UE can map data packets received from the remote terminal's radio bearer to the PC5 RLC channel associated with that radio bearer.

[0074] In some cases, the terminal device may trigger the sidelink RRC reconfiguration procedure in the following scenarios:

[0075] Release sidelink data bearer in unicast communication;

[0076] Establishing a sidelink data bearer in unicast communication;

[0077] Modify the relevant configuration of the sidelink data bearer in unicast communication;

[0078] In the terminal-to-network relay scenario, the PC5 RLC channel between the Layer 2 relay terminal and the remote terminal is released;

[0079] In the terminal-to-network relay scenario, a PC5 RLC channel is established between the Layer 2 relay terminal and the remote terminal;

[0080] In a terminal-to-network relay scenario, modify the configuration parameters related to the PC5 RLC channel between the Layer 2 relay terminal and the remote terminal;

[0081] Reconfiguration of NR sidelink measurement reporting related parameters;

[0082] Reconfiguration of sidelink channel state information (CSI) reference signal resources and CSI reporting delay bounds;

[0083] Reconfigure the line link discontinuous reception (DRX) on the opposite terminal side.

[0084] In some scenarios, terminal devices can use unlicensed spectrum to transmit side services. LBT needs to be performed before transmitting side services. When there are services on the licensed spectrum and side services on the unlicensed spectrum at the same time, how to transmit the services is an urgent problem that needs to be solved.

[0085] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0086] FIG4 is a schematic interaction diagram of a wireless communication method 400 according to an embodiment of the present application. As shown in FIG4 , the method 400 includes at least part of the following:

[0087] S410: The terminal device adjusts the priority of the sidelink service on the unlicensed spectrum according to the channel status of the unlicensed spectrum.

[0088] That is to say, in the embodiment of the present application, the priority of the side services on the unlicensed spectrum is not fixed. The terminal device can adjust the priority of the side services on the unlicensed spectrum according to the channel status of the unlicensed spectrum, which is conducive to ensuring that the side services on the unlicensed spectrum are transmitted in an appropriate transmission mode under different channel states of the unlicensed spectrum, thereby improving transmission performance.

[0089] In some embodiments, the lower the priority value of the sideline service, the higher the priority.

[0090] In some embodiments of the present application, S410 may include:

[0091] When the channel state on the unlicensed spectrum is better, the priority of the sideline service on the unlicensed spectrum is increased, that is, the priority value of the sideline service is reduced; or

[0092] When the channel state on the unlicensed spectrum is poor, the priority of the sideline service on the unlicensed spectrum is reduced, that is, the value of the priority of the sideline service is increased.

[0093] In some embodiments, the channel status on the unlicensed spectrum is correlated with the LBT event on the unlicensed spectrum.

[0094] In some embodiments, the channel status on the unlicensed spectrum includes but is not limited to at least one of the following:

[0095] An LBT failure occurs on the unlicensed spectrum;

[0096] No LBT failure occurs on the unlicensed spectrum;

[0097] A continuous LBT failure occurs on the unlicensed spectrum;

[0098] No sustained LBT failure occurs on the unlicensed spectrum;

[0099] LBT recovery (or LBT failure recovery) occurs on the unlicensed spectrum.

[0100] It should be understood that the embodiments of the present application do not limit the method for determining LBT continuous failure and LBT recovery.

[0101] In some embodiments, if an LBT failure or persistent LBT failure occurs on the unlicensed spectrum, the channel state on the unlicensed spectrum is considered poor. Therefore, when an LBT failure or persistent LBT failure occurs, the terminal device can lower the priority of the side traffic on the unlicensed spectrum. This allows the other services on the licensed spectrum to be transmitted first when the side traffic on the unlicensed spectrum conflicts with other services on the licensed spectrum, thereby improving overall transmission performance.

[0102] In some embodiments, if no LBT failure or persistent LBT failure occurs on the unlicensed spectrum, or if LBT recovery occurs, the channel state on the unlicensed spectrum is considered superior. Therefore, if no LBT failure or persistent LBT failure occurs, or if LBT recovery occurs, the terminal device can increase the priority of the side traffic on the unlicensed spectrum, thereby prioritizing the transmission of the side traffic on the unlicensed spectrum and improving overall transmission performance.

[0103] In some embodiments of the present application, the step 410 includes:

[0104] Adjust the priority of the side traffic on the unlicensed spectrum according to the channel status on the unlicensed spectrum and the first information, wherein the first information is used to indicate the adjustment information of the priority of the side traffic on the unlicensed spectrum, and the adjustment information is related to the channel status on the unlicensed spectrum.

[0105] In some embodiments, the first information is related to the channel status of the unlicensed spectrum, and may also include the first information being related to an LBT event on the unlicensed spectrum.

[0106] In some embodiments, the first information can be used to determine the target priority (i.e., the adjusted priority) of the side traffic on the unlicensed spectrum. For example, the first information is used to determine the adjustment amount (or, the adjusted priority) of the priority of the side traffic on the unlicensed spectrum when a specific LBT event occurs, or the adjustment amount (or, the adjusted priority) of the priority of the side traffic on the unlicensed spectrum when the LBT event on the unlicensed spectrum is converted from one LBT event to another LBT event, or, it can also be used to determine the correspondence between the priorities of the side traffic on the unlicensed spectrum before and after the occurrence of a specific LBT event, or, the correspondence between the priorities of the side traffic on the unlicensed spectrum when the LBT event on the unlicensed spectrum is converted from one LBT event to another LBT event.

[0107] Optionally, different priority adjustment amounts may correspond to different LBT events (or different channel states), or different priority adjustment amounts may correspond to different initial priorities. This application does not limit the specific adjustment method.

[0108] In some embodiments, the first information is used to indicate a correspondence between the channel state on the unlicensed spectrum and adjustment information of the priority of the side traffic on the unlicensed spectrum. The adjustment information here may refer to an adjustment amount, or may also refer to an adjusted priority.

[0109] Example 1: The first information is used to indicate a correspondence between a channel state on an unlicensed spectrum and an adjustment amount of a priority of a sidelink service on the unlicensed spectrum.

[0110] In a specific embodiment, the first information includes but is not limited to at least one of the following:

[0111] The first indication information is used to indicate an adjustment amount of the priority of the sidewalk service on the unlicensed spectrum when the first LBT event occurs relative to the priority of the sidewalk service on the unlicensed spectrum when the first LBT event does not occur;

[0112] The second indication information is used to indicate an adjustment amount of the priority of the sidewalk service on the unlicensed spectrum when the second LBT event occurs relative to the priority of the sidewalk service on the unlicensed spectrum when the first LBT event occurs;

[0113] The third indication information is used to indicate the adjustment amount of the priority of the side traffic on the unlicensed spectrum when the second LBT event occurs relative to the priority of the side traffic on the unlicensed spectrum when the first LBT event does not occur.

[0114] Example 2: The first information is used to indicate the correspondence between the channel state on the unlicensed spectrum and the adjusted priority of the sidelink service on the unlicensed spectrum.

[0115] In a specific embodiment, the first information includes but is not limited to at least one of the following:

[0116] A first correspondence relationship is used to indicate a correspondence relationship between the priority of the side traffic on the unlicensed spectrum when the first LBT event does not occur and the priority of the side traffic on the unlicensed spectrum when the first LBT event occurs;

[0117] The second correspondence is used to indicate the correspondence between the priority of the side traffic on the unlicensed spectrum when the second LBT event occurs and the priority of the side traffic on the unlicensed spectrum when the first LBT event occurs;

[0118] A third correspondence is used to indicate a correspondence between the priority of the side traffic on the unlicensed spectrum when the first LBT event does not occur and the priority of the side traffic on the unlicensed spectrum when the second LBT event occurs;

[0119] A first priority level, used to indicate an adjusted priority level of the side traffic on the unlicensed spectrum when a first LBT event occurs;

[0120] The second priority is used to indicate the adjusted priority of the side traffic on the unlicensed spectrum in the event of a second LBT event.

[0121] In some embodiments, the first LBT event may be an event indicating a poor channel state on the unlicensed spectrum, including but not limited to an LBT failure event and / or an LBT continuous failure event. The following description uses the LBT failure event as an example, but the present application is not limited thereto.

[0122] In some embodiments, the second LBT event may be an event indicating that the channel status on the unlicensed spectrum is better, for example including but not limited to an LBT recovery event.

[0123] In some embodiments, the first indication information is used to indicate a first adjustment amount. When an LBT failure occurs, the terminal device may determine the adjusted priority of the side traffic on the unlicensed spectrum when the LBT failure occurs based on the priority of the side traffic on the unlicensed spectrum when the LBT failure does not occur and the first adjustment amount.

[0124] In some embodiments, the second indication information is used to indicate a second adjustment amount. When LBT recovery occurs, the terminal device may determine the adjusted priority of the side traffic on the unlicensed spectrum when LBT recovery occurs based on the priority of the side traffic on the unlicensed spectrum when the LBT failure occurs and the second adjustment amount.

[0125] In some embodiments, the third indication information is used to indicate a third adjustment amount. When LBT recovery occurs, the terminal device may determine the adjusted priority of the side traffic on the unlicensed spectrum when LBT recovery occurs based on the priority of the side traffic on the unlicensed spectrum when no LBT failure occurs and the third adjustment amount.

[0126] In some embodiments, the first adjustment amount can be a positive value. When an LBT failure occurs, the terminal device can add the first adjustment amount to the priority of the side service on the unlicensed spectrum when no LBT failure occurs, and obtain the adjusted priority of the side service on the unlicensed spectrum when the LBT failure occurs, thereby achieving the purpose of lowering the priority of the side service on the unlicensed spectrum, and further causing the side service on the unlicensed spectrum to be transmitted with low priority.

[0127] In some embodiments, the second adjustment amount can be a negative value. Then, when LBT recovery occurs, the terminal device can add the second adjustment amount to the priority of the side service on the unlicensed spectrum when LBT failure occurs, and obtain the adjusted priority of the side service on the unlicensed spectrum when LBT recovery occurs, thereby achieving the purpose of improving the priority of the side service on the unlicensed spectrum, and further allowing the side service on the unlicensed spectrum to be transmitted preferentially.

[0128] In some embodiments, the third adjustment amount can be a negative value. Then, when LBT recovery occurs, the terminal device can add the third adjustment amount to the priority of the side traffic on the unlicensed spectrum when no LBT failure occurs, and obtain the adjusted priority of the side traffic on the unlicensed spectrum when LBT recovery occurs, thereby achieving the purpose of improving the priority of the side traffic on the unlicensed spectrum, and further allowing the side traffic on the unlicensed spectrum to be transmitted preferentially.

[0129] In some embodiments, when a first LBT event occurs, the terminal device may adjust the priority of the side traffic on the unlicensed spectrum to the first priority. For example, when a first LBT event occurs, the terminal device may adjust the priority of all side traffic on the unlicensed spectrum to a fixed priority.

[0130] In some embodiments, when the second LBT event occurs, the terminal device may adjust the priority of the side traffic on the unlicensed spectrum to the second priority. For example, when the second LBT event occurs, the terminal device may adjust the priority of all side traffic on the unlicensed spectrum to a fixed priority.

[0131] In some embodiments, the first correspondence is used to indicate the correspondence between the priority of the side traffic on the unlicensed spectrum when an LBT failure occurs and the priority of the side traffic on the unlicensed spectrum when no LBT failure occurs.

[0132] Optionally, in the first correspondence, the priority of the side traffic on the unlicensed spectrum in the event of an LBT failure is priority 1, and the priority of the side traffic on the unlicensed spectrum in the event of no LBT failure is priority 2, wherein the value of priority 1 is higher than the value of priority 2, that is, the priority corresponding to the side traffic on the unlicensed spectrum in the event of an LBT failure is lower than the priority corresponding to the side traffic on the unlicensed spectrum in the event of no LBT failure.

[0133] Therefore, by adjusting the priority of the side services on the unlicensed spectrum based on the first corresponding relationship, it is possible to adjust the priority of the side services on the unlicensed spectrum to a lower priority when an LBT failure occurs, so that the side services on the unlicensed spectrum are transmitted with low priority, and then the services on the licensed spectrum are transmitted with priority, thereby improving the overall transmission performance.

[0134] In some embodiments, the second correspondence is used to indicate the correspondence between the priority of the side traffic on the unlicensed spectrum when LBT recovery occurs and the priority of the side traffic on the unlicensed spectrum when LBT failure occurs.

[0135] Optionally, in the second correspondence, the priority of the side traffic on the unlicensed spectrum when LBT recovery occurs is priority 3, and the priority of the side traffic on the unlicensed spectrum when LBT failure occurs is priority 4, wherein the value of priority 4 is higher than the value of priority 3, that is, the priority corresponding to the side traffic on the unlicensed spectrum when LBT failure occurs is lower than the priority corresponding to the side traffic on the unlicensed spectrum when LBT recovery occurs.

[0136] Therefore, by adjusting the priority of the side services on the unlicensed spectrum based on the second corresponding relationship, it is possible to adjust the priority of the side services on the unlicensed spectrum to a higher priority when LBT recovery occurs, so that the side services on the unlicensed spectrum are transmitted first, thereby improving the overall transmission performance.

[0137] In some embodiments, the third correspondence is used to indicate the correspondence between the priority of the side traffic on the unlicensed spectrum when LBT recovery occurs and the priority of the side traffic on the unlicensed spectrum when no LBT failure occurs.

[0138] Optionally, in the third correspondence, the priority of the side traffic on the unlicensed spectrum when no LBT failure occurs is priority 5, and the priority of the side traffic on the unlicensed spectrum when no LBT failure occurs is priority 6, wherein the value of priority 6 is higher than the value of priority 5, that is, the priority corresponding to the side traffic on the unlicensed spectrum when no LBT failure occurs is lower than the priority corresponding to the side traffic on the unlicensed spectrum when LBT recovery occurs.

[0139] Therefore, by adjusting the priority of the side services on the unlicensed spectrum based on the third corresponding relationship, it is possible to adjust the priority of the side services on the unlicensed spectrum to a higher priority when LBT recovery occurs, so that the side services on the unlicensed spectrum are transmitted first, thereby improving the overall transmission performance.

[0140] It should be understood that the specific content included in the first information and the method of adjusting the priority of the side traffic on the unlicensed spectrum according to the channel status on the unlicensed spectrum are merely examples, and the present application is not limited thereto.

[0141] In some embodiments, the first information is configured by the network device, or is predefined, or is determined according to a preset rule.

[0142] It should be understood that all the content in the first information may be configured by the network device, or part of the content may be configured by the network device, and the rest of the content may be predefined or determined according to preset rules. This application does not limit this.

[0143] That is, the network device and the terminal device have the same understanding of the first information.

[0144] In some embodiments of the present application, the method 400 further includes:

[0145] S401: The network device sends first information to the terminal device.

[0146] In some embodiments, the first information may be configured by at least one of the following signaling:

[0147] Broadcast messages, dedicated signaling, such as RRC signaling.

[0148] Optionally, for a terminal device in an RRC idle state or an inactive state, the network device may send the first information via a broadcast message.

[0149] Optionally, for a terminal device in an RRC connected state, the network device may send the first information via dedicated signaling.

[0150] Optionally, for terminal devices outside the coverage area, the first information may be obtained in a pre-configuration manner.

[0151] In some embodiments of the present application, the S410 may include:

[0152] When a first LBT event or a second LBT event occurs on the unlicensed spectrum, the priority of the side traffic on the unlicensed spectrum is adjusted according to the channel status on the unlicensed spectrum.

[0153] In some embodiments, when an LBT failure occurs on the unlicensed spectrum, the terminal device adjusts the priority of the side traffic on the unlicensed spectrum according to the first indication information, the first correspondence or the first priority.

[0154] For example, the priority of the sideline service when no LBT failure occurs is added to the adjustment amount indicated by the first indication information as the adjusted priority of the sideline service, wherein the adjustment amount indicated by the first indication information is a positive value.

[0155] For another example, the priority of the sideline service when no LBT failure occurs in the first corresponding relationship is determined to be the priority corresponding to the priority when the LBT failure occurs, and the corresponding priority is determined as the adjusted priority of the sideline service.

[0156] For another example, the first priority is determined as the adjusted priority of the sideline service.

[0157] In other embodiments, when LBT recovery occurs on the unlicensed spectrum, the terminal device adjusts your sideline priority on the unlicensed spectrum according to the second indication information, the third indication information, the second correspondence, the third correspondence or the second priority.

[0158] For example, the priority of the sideline service when an LBT failure occurs is added to the adjustment amount indicated by the second indication information as the adjusted priority of the sideline service, wherein the adjustment amount indicated by the second indication information is a negative value. Alternatively, the priority of the sideline service when no LBT failure occurs is added to the adjustment amount indicated by the third indication information as the adjusted priority of the sideline service, wherein the adjustment amount indicated by the third indication information is a negative value.

[0159] For another example, the priority of the sideline service when LBT failure occurs in the second correspondence is determined to correspond to the priority when LBT is restored, and the corresponding priority is determined as the adjusted priority of the sideline service. Alternatively, the priority of the sideline service when LBT failure does not occur in the third correspondence is determined to correspond to the priority when LBT is restored, and the corresponding priority is determined as the adjusted priority of the sideline service.

[0160] For another example, the second priority is determined as the adjusted priority of the sideline service.

[0161] In some embodiments of the present application, the method 400 further includes:

[0162] According to the priorities of multiple services to be transmitted, prioritized services and / or de-prioritized services are determined among the multiple services to be transmitted, and the multiple services to be transmitted include side services on unlicensed spectrum and services on licensed spectrum.

[0163] In an embodiment of the present application, the priority of the side service on the unlicensed spectrum may be the adjusted priority of the side service (for the specific adjustment method, refer to the relevant description of the aforementioned embodiment), or it may be the unadjusted priority.

[0164] For ease of distinction and explanation, in the following text, the priority of the side service on the unlicensed spectrum refers to the unadjusted priority, and the adjusted priority of the side service on the unlicensed spectrum refers to the priority adjusted according to the channel status on the unlicensed spectrum.

[0165] In some embodiments, the multiple services to be transmitted include at least two of the following services:

[0166] Sidelink services on licensed spectrum, sidelink services on unlicensed spectrum, and uplink services.

[0167] In some embodiments, the side traffic on the licensed spectrum may include but is not limited to the side traffic in the LTE system, such as V2X traffic.

[0168] In some embodiments, the side traffic on the unlicensed spectrum may include but is not limited to the side traffic on the unlicensed spectrum in the NR system.

[0169] It should be understood that in some embodiments of the present application, when there are multiple services to be transmitted, the terminal device may first determine whether the terminal device is capable of transmitting the multiple services to be transmitted. In the case where the terminal device is capable of transmitting the multiple services to be transmitted at the same time, the terminal device may determine to transmit the multiple services to be transmitted at the same time. In the case where the terminal device is not capable of transmitting the multiple services to be transmitted at the same time, the terminal device may determine the services to be transmitted with priority and / or the services to be transmitted with low priority among the multiple services to be transmitted. For example, the terminal device determines the services to be transmitted with priority and / or the services to be transmitted with low priority based on the priorities of the multiple services to be transmitted and / or the channel status of the unlicensed spectrum.

[0170] Optionally, in some embodiments, when the terminal device determines a service to be transmitted with priority and / or a service to be transmitted with low priority among multiple services to be transmitted, it may directly compare the priorities of the multiple services to be transmitted, or it may also compare the priority of the service to be transmitted with the corresponding priority threshold. For example, a service with a priority higher than the priority threshold is determined to be a service that can be transmitted with priority, and a service with a priority lower than the priority threshold is determined to be a service that cannot be transmitted with priority (or, a service with low priority).

[0171] Scenario 1: The multiple services to be transmitted include side services on the licensed spectrum and side services on the unlicensed spectrum.

[0172] In this scenario, the terminal device can compare the priorities of the multiple services to be transmitted to determine the services to be transmitted with priority and / or the services to be transmitted with low priority.

[0173] Scenario 2: The multiple services to be transmitted include uplink services and sidelink services on unlicensed spectrum.

[0174] In this scenario, the terminal device can compare the priority thresholds corresponding to the uplink service and the sidelink service on the authorized spectrum to determine the service to be transmitted with priority and / or the service to be transmitted with low priority.

[0175] In some embodiments, the priority threshold of the side traffic on the unlicensed spectrum may be a first priority threshold.

[0176] Optionally, the first priority threshold may be a priority threshold dedicated to the side traffic on the unlicensed spectrum, or may be a priority threshold shared by the side traffic on the unlicensed spectrum and the side traffic on the licensed spectrum.

[0177] In some embodiments, the first priority threshold may be configured by the network device, or may be predefined, or may be determined according to a preset rule.

[0178] In some embodiments, if the priority of the side service on the unlicensed spectrum is higher than the first priority threshold (i.e., the value of the priority is less than the first priority threshold), it indicates that the terminal device can give priority to transmitting the side service on the unlicensed spectrum, that is, the side service can be transmitted with priority. Alternatively, if the priority of the side service on the unlicensed spectrum is lower than the first priority threshold (i.e., the value of the priority is greater than the first priority threshold), it indicates that the terminal device cannot give priority to transmitting the side service on the unlicensed spectrum, that is, the side service cannot be transmitted with priority.

[0179] Hereinafter, the transmission modes of services in the above-mentioned scenarios 1 and 2 will be described respectively in combination with Example 1 and Example 2.

[0180] Example 1: Multiple services to be transmitted include side services on the licensed spectrum and side services on the unlicensed spectrum

[0181] In some embodiments, when the terminal device is capable of simultaneously transmitting side traffic on the licensed spectrum and side traffic on the unlicensed spectrum, the terminal device may simultaneously transmit side traffic on the licensed spectrum and side traffic on the unlicensed spectrum.

[0182] In some embodiments, when the terminal device cannot simultaneously transmit the side traffic on the licensed spectrum and the side traffic on the unlicensed spectrum, the terminal device may determine the priority transmission service and / or the low priority transmission service based on at least one of the priority of the side traffic on the licensed spectrum, the target priority of the side traffic on the unlicensed spectrum, and the channel status on the unlicensed spectrum.

[0183] Optionally, the terminal device may compare the priority of the side service on the licensed spectrum with the target priority of the side service on the unlicensed spectrum to determine the service to be transmitted with priority and / or the service to be transmitted with low priority, wherein the target priority of the side service on the unlicensed spectrum may be the priority adjusted according to the channel status on the unlicensed spectrum (for the specific adjustment method, refer to the relevant description of the aforementioned embodiment), or it may also be the unadjusted priority of the side service on the unlicensed spectrum.

[0184] For example, when the target priority of the side traffic on the unlicensed spectrum is higher than the priority of the side traffic on the licensed spectrum, the terminal device can prioritize the transmission of the side traffic on the unlicensed spectrum and / or transmit the side traffic on the licensed spectrum with low priority.

[0185] For another example, when the priority of the side traffic on the licensed spectrum is higher than the target priority of the side traffic on the unlicensed spectrum, the terminal device may transmit the side traffic on the licensed spectrum first and / or transmit the side traffic on the unlicensed spectrum with low priority.

[0186] Example 1-1:

[0187] In some embodiments, when a first LBT event or a second LBT event occurs on the unlicensed spectrum, the terminal device determines the priority transmission service and / or low priority transmission service based on the adjusted priority of the side traffic on the unlicensed spectrum (for the specific adjustment method, refer to the relevant description of the aforementioned embodiment) and the priority of the side traffic on the licensed spectrum.

[0188] For example, if the adjusted priority of the side traffic on the unlicensed spectrum is higher than the priority of the side traffic on the licensed spectrum, it is determined to prioritize the transmission of the side traffic on the unlicensed spectrum and / or to transmit the side traffic on the licensed spectrum with low priority.

[0189] For another example, if the adjusted priority of the side traffic on the unlicensed spectrum is lower than the priority of the side traffic on the authorized spectrum, it is determined to prioritize the transmission of the side traffic on the authorized spectrum and / or to transmit the side traffic on the unlicensed spectrum with low priority.

[0190] Example 1-2:

[0191] In some embodiments, when the first LBT event does not occur on the unlicensed spectrum, the terminal device determines the priority transmission service and / or low priority transmission service based on the priority of the side traffic on the unlicensed spectrum (i.e., without adjusting the priority) and the priority of the side traffic on the licensed spectrum.

[0192] For example, if the priority of the side traffic on the unlicensed spectrum is higher than the priority of the side traffic on the licensed spectrum, it is determined to prioritize the transmission of the side traffic on the unlicensed spectrum and / or to transmit the side traffic on the licensed spectrum with low priority.

[0193] For another example, if the priority of the side traffic on the unlicensed spectrum is lower than the priority of the side traffic on the authorized spectrum, it is determined to prioritize the transmission of the side traffic on the authorized spectrum and / or to transmit the side traffic on the unlicensed spectrum with low priority.

[0194] Example 1-3:

[0195] In some embodiments, when the terminal device cannot obtain the first information, the terminal device can determine the priority transmission services and / or low priority transmission services based on the channel status on the unlicensed spectrum, the priority of the side services on the unlicensed spectrum (i.e., without adjusting the priority) and the priority of the side services on the licensed spectrum.

[0196] Optionally, if no LBT failure event or no LBT continuous failure event occurs on the unlicensed spectrum, the terminal device may determine the priority transmission service and / or the low priority transmission service based on the priority of the side traffic on the unlicensed spectrum (i.e., without adjusting the priority) and the priority of the side traffic on the authorized spectrum. For example, if the priority of the side traffic on the unlicensed spectrum is higher than the priority of the side traffic on the authorized spectrum, it is determined to prioritize the transmission of the side traffic on the unlicensed spectrum and / or to transmit the side traffic on the authorized spectrum with low priority. For another example, if the priority of the side traffic on the unlicensed spectrum is lower than the priority of the side traffic on the authorized spectrum, it is determined to prioritize the transmission of the side traffic on the authorized spectrum and / or to transmit the side traffic on the unlicensed spectrum with low priority.

[0197] Optionally, if an LBT failure event or an LBT continuous failure event occurs on the unlicensed spectrum, the terminal device may determine to prioritize the transmission of the side traffic on the licensed spectrum and / or to transmit the side traffic on the unlicensed spectrum with low priority.

[0198] Optionally, if an LBT recovery event occurs on the unlicensed spectrum, the terminal device may determine to prioritize transmission of the side traffic on the unlicensed spectrum and / or to give low priority to transmission of the side traffic on the licensed spectrum.

[0199] It should be understood that the above-mentioned embodiments 1-1, 1-2 and 1-3 may be executed when the terminal device cannot simultaneously transmit the multiple services to be transmitted, or may be irrelevant to the capabilities of the terminal device, and this application does not limit this.

[0200] In some embodiments of the present application, the terminal device may determine to prioritize transmission of the side traffic on the licensed spectrum and / or to prioritize transmission of the side traffic on the unlicensed spectrum when the first condition is met;

[0201] The first condition includes at least one of the following:

[0202] A first LBT event occurs on the unlicensed spectrum;

[0203] The priority of the side traffic on the licensed spectrum is higher than the priority of the side traffic on the unlicensed spectrum;

[0204] The priority of the side traffic on the licensed spectrum is higher than the adjusted priority of the side traffic on the unlicensed spectrum.

[0205] In some embodiments of the present application, the terminal device may determine to prioritize transmission of the side traffic on the unlicensed spectrum and / or to give low priority transmission of the side traffic on the licensed spectrum when the second condition is met;

[0206] The second condition includes at least one of the following:

[0207] No first LBT event occurs in the unlicensed spectrum;

[0208] A second LBT event occurs on the unlicensed spectrum;

[0209] The priority of the side traffic on the unlicensed spectrum is higher than the priority of the side traffic on the licensed spectrum;

[0210] The adjusted priority of the side traffic on the unlicensed spectrum is higher than the priority of the side traffic on the licensed spectrum.

[0211] Embodiment 2: Multiple services to be transmitted include sidelink services and uplink services on the unlicensed spectrum

[0212] In some embodiments, when the multiple services to be transmitted include uplink services, it can be determined whether to transmit the uplink services first according to the priority of the uplink services.

[0213] For example, when the priority of the uplink service is higher than the priority threshold corresponding to the uplink service (i.e., the priority of the uplink service is higher), it is determined to prioritize the transmission of the uplink service and / or low-priority transmission of the side service on the unlicensed spectrum.

[0214] For another example, when the priority of the uplink service is lower than the priority threshold corresponding to the uplink service (i.e., the priority of the uplink service is low), the terminal device can determine the priority transmission service and / or the low priority transmission service based on whether the side service on the unlicensed spectrum can be transmitted first. Optionally, the terminal device can determine whether the side service on the unlicensed spectrum can be transmitted first based on the target priority of the side service on the unlicensed spectrum.

[0215] That is to say, when the priority of the uplink service is lower than the priority threshold corresponding to the uplink service, the terminal device can determine the priority transmission service and / or low priority transmission service based on the target priority of the side service on the unlicensed spectrum.

[0216] Optionally, the target priority of the side traffic on the unlicensed spectrum may be a priority adjusted according to a channel state on the unlicensed spectrum, or may be an unadjusted priority of the side traffic on the unlicensed spectrum.

[0217] Optionally, when a first LBT event or a second LBT event occurs on the unlicensed spectrum, the terminal device determines the priority transmission service and / or low priority transmission service based on the adjusted priority of the side traffic on the unlicensed spectrum.

[0218] Optionally, when no first LBT event occurs on the unlicensed spectrum, the terminal device determines the priority transmission services and / or low priority transmission services based on the unadjusted priority of the side traffic on the unlicensed spectrum.

[0219] In a specific example, when the target priority of the side traffic on the unlicensed spectrum is higher than or equal to (or higher than) the priority threshold corresponding to the side traffic on the unlicensed spectrum (i.e., the side traffic on the unlicensed spectrum can be transmitted with priority, or in other words, the priority of the side traffic on the unlicensed spectrum is higher), it is determined to give priority to transmitting the side traffic on the unlicensed spectrum and / or to transmit the uplink traffic with low priority.

[0220] In a specific example, when the target priority of the side traffic on the unlicensed spectrum is lower than (or, lower than or equal to) the priority threshold corresponding to the side traffic on the unlicensed spectrum (i.e., the side traffic on the unlicensed spectrum cannot be transmitted with priority, or in other words, the priority of the side traffic on the unlicensed spectrum is low), it is determined to give priority to transmitting the uplink traffic and / or to transmit the side traffic on the unlicensed spectrum with low priority.

[0221] Example 2-1:

[0222] In some embodiments, when the first LBT event does not occur on the unlicensed spectrum, the priority transmission service and / or the low priority transmission service are determined based on the priority of the side traffic on the unlicensed spectrum (i.e., the priority is not adjusted) and the priority threshold corresponding to the side traffic on the unlicensed spectrum. For example, when the priority of the side traffic on the unlicensed spectrum is higher than or equal to the priority threshold corresponding to the side traffic on the unlicensed spectrum, it is determined to prioritize the transmission of the side traffic on the unlicensed spectrum and / or to prioritize the transmission of the uplink traffic. For another example, when the priority of the side traffic on the unlicensed spectrum is lower than the priority threshold corresponding to the side traffic on the unlicensed spectrum, it is determined to prioritize the transmission of the uplink traffic and / or prioritize the transmission of the side traffic on the unlicensed spectrum.

[0223] Example 2-2:

[0224] In some embodiments, when a first LBT event or a second LBT event occurs on the unlicensed spectrum, the terminal device determines the priority transmission service and / or the low priority transmission service based on the adjusted priority of the side traffic on the unlicensed spectrum and the priority threshold corresponding to the side traffic on the unlicensed spectrum.

[0225] For example, if the adjusted priority of the side service on the unlicensed spectrum is higher than or equal to the priority threshold corresponding to the side service on the unlicensed spectrum, it is determined to give priority to transmitting the side service on the unlicensed spectrum and / or to transmit the uplink service with low priority.

[0226] For another example, if the adjusted priority of the side traffic on the unlicensed spectrum is lower than the priority threshold corresponding to the side traffic on the unlicensed spectrum, it is determined to prioritize the transmission of the uplink traffic and / or transmit the side traffic on the unlicensed spectrum with low priority.

[0227] Example 2-3:

[0228] In some embodiments, when the terminal device cannot obtain the first information, the terminal device can determine the priority transmission services and / or low priority transmission services based on the channel status on the unlicensed spectrum, the priority of the sidelink services on the unlicensed spectrum (i.e., without adjusting the priority) and the priority of the uplink services.

[0229] Optionally, if the priority of the uplink service is higher than or equal to the priority threshold corresponding to the uplink service, it is determined to prioritize transmission of the uplink service and / or low-priority transmission of the sidelink service on the unlicensed spectrum.

[0230] Optionally, if the priority of the uplink service is lower than the priority threshold corresponding to the uplink service, the priority transmission service and / or low priority transmission service is determined based on the priority of the sidelink service on the unlicensed spectrum (i.e., the priority is not adjusted) and the channel status on the unlicensed spectrum.

[0231] For example, if no LBT failure event or LBT continuous failure event occurs on the unlicensed spectrum, the terminal device can determine to give priority to transmitting the sidelink service on the unlicensed spectrum and / or transmit the uplink service with low priority.

[0232] For another example, if an LBT failure event or an LBT continuous failure event occurs on the unlicensed spectrum, the terminal device may determine to prioritize transmission of uplink services and / or low-priority transmission of side services on the unlicensed spectrum.

[0233] For another example, if an LBT recovery event occurs on the unlicensed spectrum, the terminal device may determine to prioritize the transmission of the sidelink service on the unlicensed spectrum and / or to transmit the uplink service with low priority.

[0234] It should be understood that the above-mentioned embodiments 2-1, 2-2 and 2-3 may be executed when the terminal device cannot simultaneously transmit the multiple services to be transmitted, or may be irrelevant to the capabilities of the terminal device, and this application does not limit this.

[0235] In some embodiments of the present application, the terminal device may determine to prioritize transmission of the sidelink service on the unlicensed spectrum and / or to transmit the uplink service with low priority when a third condition is met, wherein the third condition includes at least one of the following:

[0236] No first LBT event occurs in the unlicensed spectrum;

[0237] A second LBT event occurs on the unlicensed spectrum;

[0238] The priority of the uplink service is lower than the priority threshold corresponding to the uplink service;

[0239] The priority of the side traffic on the unlicensed spectrum is higher than the priority threshold corresponding to the side traffic on the unlicensed spectrum;

[0240] The adjusted priority of the side traffic on the unlicensed spectrum is higher than a priority threshold corresponding to the side traffic on the unlicensed spectrum.

[0241] In some embodiments of the present application, the terminal device may determine to prioritize transmission of the uplink service and / or to prioritize transmission of the sidelink service on the unlicensed spectrum when a fourth condition is met, wherein the fourth condition includes at least one of the following:

[0242] A first LBT event occurs on the unlicensed spectrum;

[0243] The priority of the uplink service is higher than the priority threshold corresponding to the uplink service;

[0244] The priority of the side traffic on the unlicensed spectrum is lower than the priority threshold corresponding to the side traffic on the unlicensed spectrum;

[0245] The adjusted priority of the side traffic on the unlicensed spectrum is lower than a priority threshold corresponding to the side traffic on the unlicensed spectrum.

[0246] It should be understood that the above-mentioned embodiment 1 and embodiment 2 can be implemented separately or in combination, and this application does not limit this.

[0247] In some embodiments, when multiple services to be transmitted include side services on licensed spectrum, side services on unlicensed spectrum and uplink services, the terminal device can first determine the service to be transmitted first based on the priority of the uplink service and the priority threshold corresponding to the uplink service.

[0248] For example, if the priority of the uplink service is higher than the priority threshold corresponding to the uplink service, it is determined that the uplink service is transmitted first.

[0249] For another example, if the priority of the uplink service is lower than the priority threshold corresponding to the uplink service, the service to be transmitted with priority can be determined based on the priority of the side service on the authorized spectrum and the priority of the side service on the unlicensed spectrum. For example, the service to be transmitted with priority can be determined according to the method in Example 1.

[0250] In summary, in the embodiments of the present application, the terminal device can adjust the priority of the side services on the unlicensed spectrum according to the channel status of the unlicensed spectrum, which is conducive to ensuring that the side services on the unlicensed spectrum are transmitted in an appropriate transmission mode under different channel states of the unlicensed spectrum, thereby improving transmission performance.

[0251] In some implementations, when there are side services on the unlicensed spectrum and side services on the authorized spectrum that need to be transmitted at the same time, the terminal device can select the service to be transmitted first based on the priority of the side services on the unlicensed spectrum and the priority of the side services on the authorized spectrum. When comparing based on priority, the priority of the side services on the unlicensed spectrum can be adjusted based on the channel status on the unlicensed spectrum, or it can be an unadjusted priority.

[0252] In some implementations, when both a side service and an uplink service on an unlicensed spectrum need to be transmitted, the terminal device may first determine the service to be transmitted first based on the priority of the uplink service and the priority threshold corresponding to the uplink service. For example, when the priority of the uplink service is higher than the priority threshold corresponding to the uplink service, the uplink service is transmitted first. When the priority of the uplink service is lower than the priority threshold corresponding to the uplink service, the service to be transmitted first is determined based on the priority of the side service on the unlicensed spectrum and the priority threshold corresponding to the side service on the unlicensed spectrum. For example, when the priority of the side service on the unlicensed spectrum is higher than the priority threshold corresponding to the side service on the unlicensed spectrum, the priority of the side service on the unlicensed spectrum is transmitted first. Alternatively, when the priority of the side service on the unlicensed spectrum is lower than the priority threshold corresponding to the side service on the unlicensed spectrum, the uplink service is transmitted first. The priority of the side service on the unlicensed spectrum may be obtained by adjusting the channel status on the unlicensed spectrum, or may be an unadjusted priority.

[0253] The above text, in conjunction with Figure 4, describes in detail the method embodiment of the present application. The following text, in conjunction with Figures 5 to 9, describes in detail the device embodiment of the present application. It should be understood that the device embodiment and the method embodiment correspond to each other, and similar descriptions can refer to the method embodiment.

[0254] FIG5 shows a schematic block diagram of a terminal device 500 according to an embodiment of the present application. As shown in FIG5 , the terminal device 500 includes:

[0255] The processing unit 510 is configured to adjust the priority of the sidelink service on the unlicensed spectrum according to the channel status on the unlicensed spectrum.

[0256] In some embodiments, the channel status on the unlicensed spectrum includes at least one of the following:

[0257] Listen-before-talk (LBT) failure occurs on the unlicensed spectrum;

[0258] No LBT failure occurs on the unlicensed spectrum;
