Description

A communication method, communication device and storage medium

[0001] This application claims priority to Chinese Patent Application No. 202411056478.6, filed on August 1, 2024, entitled "A Communication Method, Communication Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, communication device and storage medium. Background Technology

[0003] Because delay-critical protocol data unit (PDCP SDU) has high latency requirements during data transmission, when there is delay-critical data that needs to be transmitted in the logical channel (LCH) of the terminal device, the delay-critical data should be mapped to an uplink licensed resource for transmission.

[0004] However, there are currently no clear regulations on how to utilize uplink license resources to transmit delayed critical data, resulting in low utilization of uplink license resources and wasted resources. Summary of the Invention

[0005] This application provides a communication method, communication device, and storage medium, with the aim of improving the utilization rate of uplink licensed resources.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A first aspect of this application provides a communication method applied to a terminal device, the method comprising:

[0008] When a logical channel includes delay-critical data, the logical channel is mapped to uplink authorized resources based on resource mapping rules. The resource mapping rules are used to indicate that the uplink authorized resources can be used to transmit delay-critical data.

[0009] The data in the logical channel is sent to the network device through the uplink authorized resources.

[0010] In the above implementation scheme, in order to improve the utilization rate of uplink license resources, when the logical channel includes delay-critical data, the terminal device can map the data, including delay-critical data, on the logical channel to the uplink license resources for transmission based on the pre-configured resource mapping rules, thereby enabling the uplink license resources to be effectively utilized and improving the utilization rate of uplink license resources.

[0011] In one possible implementation of the first aspect of this application, when the resource mapping rule stipulates that the uplink licensed resources are only used for transmitting delay-critical data, mapping the logical channel to the uplink licensed resources based on the resource mapping rule includes: mapping the delay-critical data of the logical channel to the uplink licensed resources. In the above implementation, when the resource mapping rule in the terminal device specifically stipulates that the uplink licensed resources are only used for transmitting delay-critical data, the terminal device can fill the uplink licensed resources with the delay-critical data from the logical channel based on the resource mapping rule. That is, it can map the delay-critical data from the logical channel to the uplink licensed resources for transmission based on the resource mapping rule, thereby enabling the uplink licensed resources to be effectively utilized and improving their utilization rate.

[0012] In one possible implementation of the first aspect of this application, when the resource mapping rule allows the uplink grant resource to be used for transmitting delay-critical data and non-delay-critical data, the step of mapping the logical channel to the uplink grant resource based on the resource mapping rule includes: mapping the delay-critical data of the logical channel to the uplink grant resource; if the uplink grant resource has a first remaining resource, then mapping the non-delay-critical data of the logical channel to the uplink grant resource, wherein the first remaining resource is the mappable resource in the uplink grant resource after mapping all delay-critical data in the logical channel to the uplink grant resource. In the above implementation scheme, when the resource mapping rule in the terminal device is specifically that the uplink authorized resources can be used to transmit delay-critical data and non-delay-critical data, the terminal device can first fill the uplink authorized resources with delay-critical data in the logical channel based on the resource mapping rule. If there are still first remaining resources that can be mapped after filling all the delay-critical data, then the non-delay-critical data in the logical channel can be mapped to fill the first remaining resources of the uplink authorized resources. That is, the delay-critical data and non-delay-critical data in the logical channel can be mapped to the uplink authorized resources for transmission based on the resource mapping rule, thereby enabling the uplink authorized resources to be effectively utilized and improving the utilization rate of the uplink authorized resources.

[0013] In one possible implementation of the first aspect of this application, when the resource mapping rule stipulates that the uplink licensed resources are only used for transmitting data in a delay-critical logical channel, mapping the logical channel to the uplink licensed resources based on the resource mapping rule includes: mapping the delay-critical logical channel to the uplink licensed resources; wherein, the delay-critical logical channel is a logical channel that includes delay-critical data. In the above implementation, when the resource mapping rule in the terminal device specifically stipulates that the uplink licensed resources are only used for transmitting data in a delay-critical logical channel, the terminal device can fill the uplink licensed resources with data from the delay-critical logical channel that includes delay-critical data based on the resource mapping rule. That is, the entire channel of the delay-critical logical channel can be mapped to the uplink licensed resources for transmission, thereby enabling the uplink licensed resources to be effectively utilized and improving the utilization rate of the uplink licensed resources.

[0014] In one possible implementation of the first aspect of this application, when the resource mapping rule allows the uplink grant resource to be used for transmitting delay-critical logical channels and non-delay-critical logical channels, the step of mapping logical channels to uplink grant resources based on the resource mapping rule includes: mapping delay-critical logical channels to the uplink grant resource; if the uplink grant resource has a second remaining resource, then mapping non-delay-critical logical channels to the uplink grant resource; wherein, the non-delay-critical logical channel is a logical channel that does not include delay-critical data; and the second remaining resource is the mappable resource in the uplink grant resource after mapping all delay-critical logical channels in the logical channel to the uplink grant resource. In the above implementation scheme, when the resource mapping rule in the terminal device is specifically that the uplink authorized resources can be used to transmit delay-critical logical channels and non-delay-critical logical channels, the terminal device can first fill the uplink authorized resources with data on delay-critical logical channels that include delay-critical data based on the resource mapping rule. If there are still second remaining resources that can be mapped after filling all delay-critical logical channels, then the second remaining resources of the uplink authorized resources can be filled with non-delay-critical logical channels that do not include delay-critical data. That is, delay-critical logical channels and non-delay-critical logical channels that conform to the delay resource mapping rule can be mapped to the uplink authorized resources for transmission, thereby enabling the uplink authorized resources to be effectively utilized and improving the utilization rate of the uplink authorized resources.

[0015] In one possible implementation of the first aspect of this application, mapping the non-delay critical logical channel to the uplink grant resource includes: mapping the non-delay critical logical channel to the uplink grant resource based on a logical channel mapping rule, wherein the logical channel mapping rule is used to indicate the uplink grant resources that the logical channel can be mapped to. In the above implementation, when the terminal device is configured with both resource mapping rules and logical channel mapping rules, the terminal device can use the logical channel mapping rules to fill the remaining resources of the uplink grant resource with data from non-delay critical logical channels that conform to both resource mapping rules and logical channel mapping rules. That is, data from non-delay critical logical channels that conform to both resource mapping rules and logical channel mapping rules can be mapped to the uplink grant resource for transmission, thereby enabling the uplink grant resource to be effectively utilized and improving its utilization rate.

[0016] In one possible implementation of the first aspect of this application, the method further includes: when all logical channels do not contain delay-critical data, mapping the logical channels to the uplink grant resources based on logical channel mapping rules, wherein the logical channel mapping rules are used to indicate the uplink grant resources that can be mapped to the logical channels. In the above implementation, when there is no delay-critical data to be transmitted in all logical channels of the terminal device, and the terminal device is configured with both resource mapping rules and logical channel mapping rules, the terminal device can ignore the resource mapping rules and map the logical channels that conform to the logical channel mapping rules to the uplink grant resources for transmission based on the logical channel mapping rules, thereby enabling the uplink grant resources to be effectively utilized and improving the utilization rate of the uplink grant resources.

[0017] In one possible implementation of the first aspect of this application, the method further includes: invalidating the resource mapping rule. In the above implementation, when there is no delay-critical data to be transmitted in any of the terminal device's logical channels, and the terminal device is configured with resource mapping rules, the terminal device can invalidate the resource mapping rules. This allows the terminal device to use other resource mapping rules or be unrestricted by the resource mapping rules to map data in the logical channels to uplink licensed resources for filling, thereby enabling the uplink licensed resources to be effectively utilized and improving their utilization rate.

[0018] In one possible implementation of the first aspect of this application, when the logical channel includes delay-critical data, the logical channel mapping rule becomes invalid. The logical channel mapping rule is used to indicate the uplink grant resources that the logical channel can be mapped to. In the above implementation, the terminal device can configure both resource mapping rules and logical channel mapping rules. When the logical channel includes delay-critical data, and the terminal device is configured with both resource mapping rules and logical channel mapping rules, the terminal device can enable only the resource mapping rules, i.e., disable the logical channel mapping rules. This allows the terminal device to map data, including delay-critical data, on the logical channel to uplink grant resources for transmission based solely on the resource mapping rules, thereby enabling effective utilization of uplink grant resources and improving their utilization rate.

[0019] In one possible implementation of the first aspect of this application, mapping a logical channel to uplink grant resources based on resource mapping rules includes: mapping the logical channel to the uplink grant resources based on the resource mapping rules and logical channel mapping rules, wherein the logical channel mapping rules are used to indicate uplink grant resources that can be mapped to the logical channel. In the above implementation, the terminal device can configure both resource mapping rules and logical channel mapping rules. The terminal device can fill uplink grant resources with data from logical channels that conform to both resource mapping rules and logical channel mapping rules, i.e., it can map data from logical channels that conform to both resource mapping rules and logical channel mapping rules to uplink grant resources for transmission, thereby enabling effective utilization of uplink grant resources and improving their utilization rate.

[0020] In one possible implementation of the first aspect of this application, the method further includes: receiving first indication information from a network device, wherein the first indication information is used to indicate resource mapping rules. In the above implementation, when a new resource mapping rule needs to be configured in the terminal device, the first indication information from the network device can be used to indicate resource mapping rules that have not been configured in the terminal device. This allows the terminal device to map data, including delay-critical data, on the logical channel to uplink licensed resources for transmission based on the resource mapping rules indicated by the network device, thereby enabling effective utilization of the uplink licensed resources and improving their utilization rate.

[0021] In one possible implementation of the first aspect of this application, the method further includes: receiving second indication information from a network device, the second indication information being used to activate the resource mapping rule indicated by the first indication information. In the above implementation, when the first indication information from the network device indicates one or more resource mapping rules, the terminal device can further determine the activated resource mapping rule from the one or more resource mapping rules indicated in the first indication information based on the second indication information from the network device. This allows the terminal device to map data, including delay-critical data, on the logical channel to uplink licensed resources for transmission according to the activated resource mapping rule, thereby enabling effective utilization of the uplink licensed resources and improving their utilization rate.

[0022] In one possible implementation of the first aspect of this application, the logical channel includes third indication information, which indicates whether the logical channel can be mapped to the uplink grant resource. Mapping the logical channel to the uplink grant resource based on resource mapping rules includes mapping the logical channel to the uplink grant resource based on the third indication information and the resource mapping rules. In the above implementation, the logical channel of the terminal device may further include third indication information that indicates whether the logical channel can be mapped to the uplink grant resource. In this case, the terminal device can determine the logical channel that can be mapped to the uplink grant resource based on the third indication information and the resource mapping rules, and fill the uplink grant resource with data from the logical channel. That is, the logical channel that can be mapped to the uplink grant resource, determined based on the third indication information and the resource mapping rules, can be mapped to the uplink grant resource for transmission, thereby enabling effective utilization of the uplink grant resource and improving its utilization rate.

[0023] In one possible implementation of the first aspect of this application, the method further includes: receiving fourth indication information from a network device, the fourth indication information being used to indicate that the resource mapping rule is invalid. In the above implementation, the terminal device can also invalidate the resource mapping rule based on the fourth indication information from the network device, so that the terminal device can use other resource mapping rules or be unrestricted by the resource mapping rules to map data in the logical channel to uplink licensed resources for filling, thereby enabling the uplink licensed resources to be effectively utilized and improving the utilization rate of the uplink licensed resources.

[0024] In one possible implementation of the first aspect of this application, according to the method of claim 1, the method is characterized in that, if the data transmitted by the uplink grant resource includes delay-critical data, the step of sending the data in the logical channel to the network device through the uplink grant resource includes: if there is a conflict with other resources when transmitting data in the logical channel through the uplink grant resource, the data in the logical channel is preferentially sent to the network device through the uplink grant resource. In the above implementation, since delay-critical data has high latency requirements during data transmission, when using the uplink grant resource to transmit delay-critical data and a conflict occurs with other resources, the priority of the uplink grant resource whose data includes delay-critical data can be higher than that of other resources. That is, the uplink grant resource that includes delay-critical data can be preferentially transmitted, thereby ensuring the validity of the delay-critical data transmitted by the uplink grant resource.

[0025] A second aspect of this application provides a communication method applied to a network device, the method comprising:

[0026] Receive data from the logical channel transmitted by the terminal device through uplink authorized resources;

[0027] Wherein, when the logical channel of the terminal device includes delay-critical data, the data in the logical channel is mapped to the uplink authorized resource by the terminal device based on resource mapping rules, and the resource mapping rules are used to indicate that the uplink authorized resource can be used to transmit delay-critical data.

[0028] In the above implementation scheme, in order to improve the utilization rate of uplink licensed resources, when the logical channel of the terminal device includes delay-critical data, the network device can receive data including delay-critical data in the logical channel that the terminal device maps to the uplink licensed resources based on the pre-configured resource mapping rules and uses the uplink licensed resources for transmission. This enables the uplink licensed resources to be effectively utilized and improves the utilization rate of uplink licensed resources.

[0029] In one possible implementation of the second aspect of this application, when all logical channels of the terminal device do not include delay-critical data, the data in the logical channels is mapped to the uplink licensed resources by the terminal device based on logical channel mapping rules, wherein the logical channel mapping rules are used to indicate the uplink licensed resources that can be mapped by the logical channels.

[0030] In one possible implementation of the second aspect of this application, the method further includes: sending first indication information to a terminal device, the first indication information being used to indicate resource mapping rules.

[0031] In one possible implementation of the second aspect of this application, the method further includes: sending second indication information to a terminal device, the second indication information being used to activate the resource mapping rule indicated by the first indication information.

[0032] In one possible implementation of the second aspect of this application, the method further includes: sending a fourth indication message to a terminal device, the fourth indication message being used to indicate that the resource mapping rule has failed.

[0033] A third aspect of this application provides a communication device, specifically a terminal device, comprising:

[0034] The mapping module is used to map the logical channel to uplink licensed resources based on resource mapping rules when the logical channel includes delay-critical data. The resource mapping rules are used to indicate that the uplink licensed resources can be used to transmit delay-critical data.

[0035] The sending module is used to send data in the logical channel to the network device through the uplink authorized resources.

[0036] A fourth aspect of this application provides a communication device, specifically a network device, comprising:

[0037] A receiving module is used to receive data in a logical channel transmitted by a terminal device through uplink authorized resources. When the logical channel of the terminal device includes delay-critical data, the data in the logical channel is mapped to the uplink authorized resources by the terminal device based on resource mapping rules. The resource mapping rules are used to indicate that the uplink authorized resources can be used to transmit delay-critical data.

[0038] A fifth aspect of this application provides a communication device, comprising: a memory and at least one processor. The memory is used to store a program, and the at least one processor is used to execute the computer program or computer instructions stored in the memory, so that the communication device implements any of the communication methods provided in the first aspect of this application.

[0039] A sixth aspect of this application provides a communication device, comprising: a memory and at least one processor. The memory is used to store a program, and the at least one processor is used to execute the computer program or computer instructions stored in the memory, so that the communication device implements any of the communication methods provided in the second aspect of this application.

[0040] The seventh aspect of this application is a computer storage medium for storing a computer program, which, when executed, implements any one of the communication methods provided in the first or second aspect of this application.

[0041] The eighth aspect of this application provides a computer program product containing instructions that, when run on a computer, cause the computer to perform any of the communication methods described in the first or second aspect above.

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application.

[0059] The embodiments of this application can be applied to communication systems, including second-generation (2G) communication systems, third-generation (3G) communication systems, LTE systems, fifth-generation (5G) communication systems, LTE and 5G hybrid architectures, 5G New Radio (5G NR) systems, and new communication systems that will emerge in the future development of communication.

[0060] A communication system may include a first device and a second device. The first device may be a network-side device used to provide network communication functions, sometimes also referred to as a network device or network element. A network device is typically a base station (including functional units of a base station, or a combination of functional units of base stations) or a core network unit. The core network unit may be a functional unit within the core network, including but not limited to Access and Mobility Management Function (AMF) units or Session Management Function (SMF) units. The second device may be a device accessing the network, typically a terminal device. An example of a communication system is shown in Figure 1, which includes a base station 11 and a terminal 12.

[0061] In the embodiments provided in this application, the base station can be any device with wireless transceiver capabilities, including but not limited to: evolved base stations (NodeB, eNB, or e-NodeB) in Long Term Evolution (LTE), base stations (gNodeB or gNB) or transmission receiving points / transmission reception points (TRPs) in New Radio (NR), base stations in subsequent 3GPP evolutions, access nodes in Wi-Fi systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: macro base station, micro base station, pico base station, small cell, relay station, or balloon station, etc. The base station can include one or more co-located or non-co-located Transmission Reception Points (TRPs). The base station can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. The base station can communicate with terminal devices or communicate with terminal devices through relay stations. Terminal devices can communicate with multiple base stations using different technologies. For example, a terminal device can communicate with a base station that supports LTE networks, or with a base station that supports 5G networks, or even have dual connections with both LTE and 5G base stations.

[0062] In the embodiments provided in this application, the terminal device can be of various forms, such as a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, an extended reality (XR) terminal device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, an in-vehicle terminal device, a wireless terminal device in self-driving, a wireless terminal device in remote medical care, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, a wearable terminal device, etc. The terminal device may also be referred to as a terminal device, user equipment (UE), access terminal device, in-vehicle terminal device, industrial control terminal device, UE unit, UE station, mobile station, mobile station, remote station, remote terminal device, mobile device, UE terminal device, terminal device, wireless communication device, UE agent, or UE device, etc. The terminal device can be a fixed terminal device or a mobile terminal device.

[0063] In communication systems, Delay-critical Protocol Data Units (PDCP SDUs) refer to service data units with high latency requirements during data transmission. The PDCP (Packet Data Convergence Protocol) layer, as a key sublayer in the Radio Access Network (RAN), is responsible for handling various functions, including data integrity, encryption, header compression, and reordering, to ensure efficient and secure data transmission. If the remaining time of delay-critical data is less than a threshold, and the PDCP layer has already submitted the data packet to the RLC (Radio Link Control) layer, it notifies the RLC layer of the dropped packet. If the RLC layer receives this indication, it can determine that the data packet is delay-critical. Delay-critical data is latency-sensitive, meaning it has high latency requirements. This implies that it needs to be transmitted from the sender to the receiver in the shortest possible time to meet the needs of real-time applications, such as voice calls and video streaming. To meet the latency requirements of delay-critical data, the network needs to dynamically adjust resource allocation, such as allocating more bandwidth or reducing the priority of other non-critical data, to ensure smooth transmission of delay-critical data.

[0064] Uplink license resources refer to the combination of parameters such as time, frequency, modulation and coding scheme, and power used for uplink data transmission, indicated by network devices to user equipment through specific signaling, such as DCI (Downlink Control Information) signaling. These resources must be adhered to by terminal equipment during uplink transmission to ensure the accuracy and reliability of data transmission. Furthermore, in 5G NR (New Radio), configuration licensing is an important method for allocating uplink license resources. It allows network devices to configure a range of uplink license resources for terminal equipment through higher-layer signaling, such as Radio Resource Control (RRC) signaling, and allows user equipment to autonomously use these resources for uplink transmission under certain conditions (such as automatic activation upon meeting specific conditions). Configuration licensing is divided into two types: Type 1 and Type 2, configured and indicated by RRC signaling and DCI signaling, respectively.

[0065] As can be seen from the above, since the latency requirements of delay-critical data are high during data transmission, when there is delay-critical data that needs to be transmitted in the logical channel (LCH) of the terminal device, the delay-critical data should be mapped to an uplink licensed resource for transmission.

[0066] However, there are currently no clear regulations on how to utilize uplink license resources for transmitting delayed critical data, resulting in low utilization of uplink license resources and wasted resources. This application provides a communication method, communication device, and storage medium that can improve the utilization rate of uplink license resources.

[0067] To make the technical solution of this application clearer and easier to understand, a communication method according to an embodiment of this application is described below with reference to the accompanying drawings. This embodiment is applicable to data transmission processes in wireless communication scenarios. This embodiment uses data transmission between a terminal device and a network device as an example, such as data transmission between a single terminal device and a network device. The above-described data transmission between a terminal device and a network device is merely a feasible example. This embodiment can be applied to data transmission between terminal devices, data transmission between network devices, or data transmission between two network elements in a wireless communication network.

[0068] Please refer to Figure 2, which shows a schematic diagram of an interaction process between a network device and a terminal device provided in an embodiment of this application. The communication method provided in this embodiment mainly includes the following steps:

[0069] 201. When the logical channel includes delay-critical data, the terminal device maps the logical channel to uplink authorized resources based on resource mapping rules.

[0070] Among them, the resource mapping rules are used to indicate that uplink authorized resources can be used to transmit latency-critical data.

[0071] In this embodiment, to improve the utilization rate of uplink license resources, when a logical channel includes delay-critical data (i.e., at least one logical channel in the terminal device includes delay-critical data), the terminal device can map the data, including delay-critical data, on the logical channel to uplink license resources based on pre-configured resource mapping rules. This allows the terminal device to transmit data, including delay-critical data, through the uplink license resources, thereby effectively utilizing the uplink license resources and improving their utilization rate. It is understood that the resource mapping rules can be pre-configured by the network device for the terminal device to restrict the data that can be transmitted using the uplink license resources; specifically, they can restrict the use of uplink license resources for transmitting delay-critical data.

[0072] Specifically, network devices can pre-configure one or more resource mapping rules for terminal devices, meaning terminal devices can pre-store one or more resource mapping rules. When a terminal device needs to utilize uplink licensed resources for data transmission, it can determine the effective resource mapping rule from the pre-configured one or more resource mapping rules, or from one or more resource mapping rules included in the configuration information sent by the network device. This allows the terminal device to map data, including delay-critical data, on the logical channel to uplink licensed resources based on the effective resource mapping rule. Consequently, it can transmit data, including delay-critical data, through the uplink licensed resources, thereby ensuring the effective utilization of uplink licensed resources and improving their utilization rate.

[0073] Furthermore, a logical channel is a channel that transmits different types of information over a physical channel. It is a logical division of the physical channel and a service provided by the Medium Access Control (MAC) entity to the upper layer to indicate what content is being carried. In this embodiment, logical channels can be divided into delay-critical logical channels and non-delay-critical logical channels based on whether they include delay-critical data. Delay-critical logical channels include delay-critical data, while non-delay-critical logical channels do not.

[0074] In this embodiment, in addition to resource mapping rules for indicating the uplink grant resources that can transmit latency-critical data, the terminal device can also be configured with logical channel mapping rules. These logical channel mapping rules restrict how logical channels are associated and mapped with transmission resources and physical channels to ensure data can be correctly transmitted in the communication system. Specifically, logical channel mapping rules indicate the uplink grant resources that can be mapped to logical channels in the terminal device; that is, the terminal device can limit the uplink grant resources that can be mapped to each logical channel based on the parameters of each logical channel. Specifically, logical channel mapping rules may include the duration of the Physical Uplink Shared Channel (PUSCH) of the uplink grant resources that can be mapped to the logical channel, whether the logical channel meets the requirements of the Subcarrier Spacing (SCS) list, whether the logical channel can use type 1 configuration grant, the serving cell that the data in the logical channel can transmit to, the configuration grant that the logical channel can use, and the dynamic grant that the logical channel can use. It is understood that the logical channel mapping rules configured by the terminal device may or may not be effective.

[0075] In one possible implementation of this application embodiment, when the logical channel includes delay-critical data, the logical channel mapping rule is invalidated. The logical channel mapping rule is used to indicate the uplink grant resources that the logical channel can be mapped to. In this application embodiment, when the logical channel includes delay-critical data, that is, at least one logical channel in the terminal device includes delay-critical data, and the terminal device is configured with both resource mapping rules and logical channel mapping rules, the terminal device can enable the resource mapping rules and disable the logical channel mapping rules. That is, the terminal device can enable only the resource mapping rules, so that when transmitting data, the terminal device can map the data, including delay-critical data, on the logical channel to uplink grant resources for transmission based solely on the resource mapping rules. This enables the uplink grant resources to be effectively utilized and improves the utilization rate of uplink grant resources.

[0076] It is understood that the resource mapping rules may include any one of the first resource mapping rule, the second resource mapping rule, the third resource mapping rule, and the fourth resource mapping rule; wherein, the first resource mapping rule is that uplink authorized resources are used only for transmitting delay-critical data; the second resource mapping rule is that uplink authorized resources can be used for transmitting both delay-critical data and non-delay-critical data; the third resource mapping rule is that uplink authorized resources are used only for transmitting data in a delay-critical logical channel, where the delay-critical logical channel is a logical channel that includes delay-critical data; and the fourth resource mapping rule is that uplink authorized resources can be used for transmitting both delay-critical logical channels and non-delay-critical logical channels, where the non-delay-critical logical channel is a logical channel that does not include delay-critical data. In the embodiments of this application, the resource mapping rules pre-configured by the terminal device may include at least one of the first, second, third, and fourth resource mapping rules, and the resource mapping rules effective in the terminal device may be any one of the first, second, third, and fourth resource mapping rules.

[0077] When the terminal device maps the logical channel to the uplink licensed resource based on the first resource mapping rule, that is, when the effective resource mapping rule is that the uplink licensed resource is only used to transmit delay-critical data, the terminal device can fill the uplink licensed resource with delay-critical data in the logical channel, but cannot map non-delay-critical data in the logical channel to the uplink licensed resource for filling. In other words, the terminal device can map delay-critical data on the logical channel to the uplink licensed resource for transmission, thereby enabling the uplink licensed resource to be effectively utilized and improving the utilization rate of the uplink licensed resource.

[0078] When the terminal device maps logical channels to uplink licensed resources based on the second resource mapping rule (i.e., the effective resource mapping rule allows uplink licensed resources to be used for transmitting delay-critical data and non-delay-critical data), the terminal device can fill the uplink licensed resources with delay-critical data and non-delay-critical data from the logical channel. Specifically, the terminal device can prioritize mapping delay-critical data on the logical channel to uplink licensed resources for transmission. If there are still remaining uplink licensed resources that can be mapped after all delay-critical data has been filled, then non-delay-critical data can be mapped to the uplink licensed resources for transmission. This ensures effective utilization of the uplink licensed resources and improves their utilization rate.

[0079] When the terminal device maps logical channels to uplink licensed resources based on the third resource mapping rule, that is, when the effective resource mapping rule is that the uplink licensed resources are only used to transmit data in the delay-critical logical channel, the terminal device can fill the uplink licensed resources with data from the delay-critical logical channel that includes delay-critical data, but cannot transmit data from the non-delay-critical logical channel that does not include delay-critical data to the uplink licensed resources. In other words, the entire delay-critical logical channel can be mapped to the uplink licensed resources for transmission, thereby enabling the uplink licensed resources to be effectively utilized and improving the utilization rate of the uplink licensed resources.

[0080] When the terminal device maps logical channels to uplink licensed resources based on the fourth resource mapping rule (i.e., the effective resource mapping rule allows uplink licensed resources to be used for transmitting delay-critical logical channels and non-delay-critical logical channels), data from both delay-critical logical channels (including delay-critical data) and non-delay-critical logical channels (excluding delay-critical data) can be used to fill uplink licensed resources. Specifically, the terminal device can prioritize mapping data from delay-critical logical channels to uplink licensed resources for transmission. If there are still unmapped uplink licensed resources after filling all delay-critical logical channels, then the remaining uplink licensed resources can be filled with non-delay-critical logical channels (excluding delay-critical data). This ensures effective utilization of uplink licensed resources and improves their utilization rate.

[0081] In one possible implementation of this application embodiment, when the resource mapping rule is that the uplink licensed resource is only used for transmitting latency-critical data, step 201, where the terminal device maps the logical channel to the uplink licensed resource based on the resource mapping rule, includes:

[0082] A1. The terminal device maps the delay-critical data in the logical channel to the uplink licensed resources.

[0083] In this embodiment, when the effective resource mapping rule in the terminal device is the first resource mapping rule (i.e., the resource mapping rule used when mapping data in the logical channel to uplink licensed resources specifically means that the uplink licensed resources are only used for transmitting delay-critical data), the terminal device can fill the uplink licensed resources with delay-critical data from the logical channel based on the first resource mapping rule. This ensures that all data filled into the uplink licensed resources is delay-critical data, meaning the terminal device can map delay-critical data from the logical channel to the uplink licensed resources for transmission based on the first resource mapping rule. This allows the uplink licensed resources to be effectively utilized, improving their utilization rate. It is understood that the total amount of delay-critical data mapped to the uplink licensed resources should not exceed the transmittable data amount of the uplink licensed resources.

[0084] Specifically, as shown in Figure 3, when the first resource mapping rule is in effect, if the terminal device has a first logical channel LCH1, a second logical channel LCH2, and a third logical channel LCH3, and LCH1 and LCH2 contain delay-critical data while LCH3 does not, then the delay-critical data in LCH1 and LCH2 can be mapped to uplink licensed resources for filling. This means that uplink licensed resources can be used to transmit the delay-critical data in LCH1 and LCH2, thereby enabling effective utilization of the uplink licensed resources and improving their utilization rate.

[0085] In one possible implementation of this application embodiment, when the resource mapping rule is that the uplink licensed resources can be used to transmit delay-critical data and non-delay-critical data, step 201, the terminal device maps the logical channel to the uplink licensed resources based on the resource mapping rule, including:

[0086] B1. The terminal device maps the latency key data of the logical channel to the uplink licensed resources.

[0087] B2. If there is a first remaining resource in the uplink grant resource, the terminal device will map the non-delay key data of the logical channel to the uplink grant resource.

[0088] The first remaining resource is the mappable resource in the uplink licensed resources after mapping all delay-critical data in the logical channel to the uplink licensed resources.

[0089] In this embodiment, when the effective resource mapping rule in the terminal device is the second resource mapping rule, that is, when the resource mapping rule used to map data in the logical channel to the uplink licensed resource is specifically that the uplink licensed resource can be used to transmit delay-critical data and non-delay-critical data, the terminal device can fill the uplink licensed resource with delay-critical data and non-delay-critical data in the logical channel, so that the data filled in the entire uplink licensed resource includes both delay-critical data and non-delay-critical data. In other words, the terminal device can map delay-critical data and non-delay-critical data in the logical channel to the uplink licensed resource for transmission based on the second resource mapping rule. Specifically, the terminal device can first map all delay-critical data in the logical channel to the uplink licensed resource for filling based on the second resource mapping rule, and then determine whether there is a first remaining resource that can be mapped after filling all delay-critical data. If there is still a first remaining resource in the uplink licensed resource, all non-delay-critical data in the logical channel can be mapped to the first remaining resource of the uplink licensed resource for filling based on the second resource mapping rule. It is understood that the total amount of delay-critical data and non-delay-critical data mapped to the uplink licensed resource should not exceed the amount of data that the uplink licensed resource can transmit.

[0090] Specifically, as shown in Figure 4, when the second resource mapping rule is in effect, if the terminal device has a first logical channel LCH1, a second logical channel LCH2, and a third logical channel LCH3, and LCH1 and LCH2 include delay-critical data while LCH3 does not, then the delay-critical data in LCH1 and LCH2 can be mapped to the uplink licensed resources for filling. If there are still first remaining resources in the uplink licensed resources, then the non-delay-critical data in LCH1, LCH2, and LCH3 can be mapped to the first remaining resources in the uplink licensed resources for filling. That is, the uplink licensed resources can be used to transmit the delay-critical data in LCH1 and LCH2 as well as the non-delay-critical data in LCH1, LCH2, and LCH3, thereby enabling the uplink licensed resources to be effectively utilized and improving the utilization rate of the uplink licensed resources.

[0091] In one possible implementation of this application embodiment, when the resource mapping rule is that the uplink licensed resources are only used for data in the transmission delay-critical logical channel, step 201, where the terminal device maps the logical channel to the uplink licensed resources based on the resource mapping rule, includes:

[0092] C1. The terminal device maps the delay-critical logical channel to the uplink licensed resource.

[0093] The delay-critical logical channel is a logical channel that includes delay-critical data.

[0094] In this embodiment, when the effective resource mapping rule in the terminal device is the third resource mapping rule, that is, when the resource mapping rule used to map data in the logical channel to the uplink licensed resource is specifically that the uplink licensed resource is only used to transmit data in the delay-critical logical channel, the terminal device can fill the uplink licensed resource with data from the delay-critical logical channel, including delay-critical data, so that the data filled into the uplink licensed resource is all data from the delay-critical logical channel. In other words, the terminal device can map data from the delay-critical logical channel in the logical channel to the uplink licensed resource for transmission based on the third resource mapping rule, thereby enabling the uplink licensed resource to be effectively utilized and improving its utilization rate. It is understood that the total amount of data in the delay-critical logical channel mapped to the uplink licensed resource should not exceed the transmittable data amount of the uplink licensed resource.

[0095] Specifically, as shown in Figure 5, when the third resource mapping rule is in effect, if the terminal device has a first logical channel LCH1, a second logical channel LCH2, and a third logical channel LCH3, and LCH1 and LCH2 contain delay-critical data (i.e., LCH1 and LCH2 are delay-critical logical channels), while LCH3 does not contain delay-critical data (i.e., LCH3 is a non-delay-critical logical channel), then all data on LCH1 and LCH2 can be mapped to uplink licensed resources for filling. This means that uplink licensed resources can be used to transmit data on delay-critical channels LCH1 and LCH2, thereby effectively utilizing the uplink licensed resources and improving their utilization rate.

[0096] Furthermore, when the terminal device is configured with not only resource mapping rules but also logical channel mapping rules, and both the third resource mapping rules and the logical channel mapping rules are in effect, the terminal device can fill uplink authorized resources with data on the delay-critical logical channels that conform to both the third resource mapping rules and the logical channel mapping rules, based on the third resource mapping rules and the logical channel mapping rules. In other words, data on logical channels that conform to both the third resource mapping rules and the logical channel mapping rules can be mapped to uplink authorized resources for transmission.

[0097] In one possible implementation of this application embodiment, when the resource mapping rule is that uplink granted resources can be used for transmission delay-critical logical channels and non-delay-critical logical channels, step 201, the terminal device maps the logical channels to uplink granted resources based on the resource mapping rule, including:

[0098] D1. The terminal device maps the delay critical logical channel to the uplink licensed resource.

[0099] D2. If there is a second remaining uplink licensed resource, the terminal device will map the non-delay critical logical channel to the uplink licensed resource.

[0100] Among them, the non-delay critical logical channel is the logical channel that does not include delay critical data; the second remaining resource is the mappable resource in the uplink authorized resource after mapping all delay critical logical channels in the logical channel to the uplink authorized resource.

[0101] In this embodiment, when the resource mapping rule in effect in the terminal device is the fourth resource mapping rule, that is, when the resource mapping rule used to map data in the logical channel to the uplink grant resource is specifically that the uplink grant resource can be used to transmit delay-critical logical channels and non-delay-critical logical channels, the terminal device can determine the delay-critical logical channel and non-delay-critical logical channel from the logical channel based on the resource mapping rule, and first fill the uplink grant resource with the data on the delay-critical logical channel. At this time, the terminal device can determine whether there is still a second remaining resource that can be mapped after the uplink grant resource has filled all the data of the delay-critical logical channels. If there is still a second remaining resource that can be mapped after filling the data on the delay-critical logical channel, then the remaining resources of the uplink grant resource are filled with the non-delay-critical logical channel that does not contain delay-critical data. The order in which the delay-critical logical channel and the non-delay-critical logical channel are mapped to the uplink grant is according to the priority order of the logical channel. In other words, terminal devices can map data from delay-critical logical channels and non-delay-critical logical channels that conform to resource mapping rules to uplink licensed resources for transmission. This enables effective utilization of uplink licensed resources and improves their utilization rate. It is understood that the data volume of non-delay-critical logical channels should not exceed the remaining uplink licensed resources; that is, the total data volume mapped to uplink licensed resources from both delay-critical and non-delay-critical logical channels should not exceed the transmittable data volume of the uplink licensed resources.

[0102] Furthermore, when the terminal device is configured with both fourth resource mapping rules and logical channel mapping rules, the fourth resource mapping rules and logical channel mapping rules can include multiple activation strategies. The first activation strategy is as follows: for delay-critical logical channels, the fourth resource mapping rule is activated; for non-delay-critical logical channels, the logical channel mapping rule is activated. The second activation strategy is as follows: for both delay-critical and non-delay-critical logical channels, both the fourth resource mapping rule and the logical channel mapping rule are activated. The third activation strategy is as follows: for delay-critical logical channels, the fourth resource mapping rule is activated; for non-delay-critical logical channels, both the fourth resource mapping rule and the logical channel mapping rule are activated.

[0103] When the terminal device adopts the first effective strategy, it can determine the delay-critical logical channels that conform to the fourth resource mapping rule from the logical channels based on the fourth resource mapping rule, and determine the non-delay-critical logical channels from the logical channels based on the logical channel mapping rule. When the terminal device adopts the second effective strategy, it can determine the delay-critical logical channels that conform to both the fourth resource mapping rule and the logical channel mapping rule from the logical channels based on the fourth resource mapping rule and the logical channel mapping rule, and determine the non-delay-critical logical channels from the logical channels based on the fourth resource mapping rule and the logical channel mapping rule. When the terminal device adopts the third effective strategy, it can determine the delay-critical logical channels that conform to both the fourth resource mapping rule and the logical channel mapping rule from the logical channels based on the fourth resource mapping rule, and determine the non-delay-critical logical channels from the logical channels based on the fourth resource mapping rule and the logical channel mapping rule. Furthermore, the uplink grant resource can be filled with data from the delay critical logic channel first. At this time, the terminal device can determine whether there are any remaining resources that can be mapped after the uplink grant resource has been filled with data from all delay critical logic channels. If there are remaining resources that can be mapped after the data from the delay critical logic channel has been filled, then the remaining resources of the uplink grant resource can be filled with data from the non-delay critical logic channel.

[0104] It is understandable that when the terminal device fills the uplink authorized resources with data on the delay critical logical channels based on the fourth resource mapping rule, if there are no second remaining resources that can be mapped after filling all the data on the delay critical logical channels, the terminal device can stop mapping. That is, it can choose not to map the data on the non-delay critical logical channels to the uplink authorized resources for transmission. In other words, when the fourth resource mapping rule is in effect, the uplink authorized resources can be filled with data on the delay critical logical channels, excluding data on the non-delay critical logical channels.

[0105] In one possible implementation of this application embodiment, if there are remaining uplink grant resources in step D2, the terminal device maps non-delayed critical logical channels to uplink grant resources, including:

[0106] D21. The terminal device maps non-delay critical logical channels to uplink licensed resources based on logical channel mapping rules.

[0107] Among them, the logical channel mapping rule is used to indicate the uplink licensed resources that can be mapped to the logical channel.

[0108] In this embodiment, when the terminal device is configured with not only resource mapping rules but also logical channel mapping rules for indicating uplink grant resources that can be mapped by logical channels, the terminal device can map data on non-delay key logical channels that can be mapped to uplink grant resources to the second remaining resources of uplink grant resources based on the logical channel mapping rules. The terminal device can also fill the second remaining resources of uplink grant resources with data on non-delay key logical channels that conform to both resource mapping rules and logical channel mapping rules based on the logical channel mapping rules. In other words, data on non-delay key logical channels that conform to both resource mapping rules and logical channel mapping rules can be mapped to uplink grant resources for transmission, thereby enabling the uplink grant resources to be effectively utilized and improving the utilization rate of uplink grant resources.

[0109] Specifically, as shown in Figure 6, when the fourth resource mapping rule is in effect, if the terminal device has a first logical channel LCH1, a second logical channel LCH2, and a third logical channel LCH3, and LCH1 and LCH2 include delay-critical data, that is, LCH1 and LCH2 are delay-critical logical channels, and LCH3 does not include delay-critical data, that is, LCH3 is a non-delay-critical logical channel. At this point, the terminal device can first map the data in LCH1 and LCH2 to the uplink licensed resources for filling based on the resource mapping rules. If there are still second remaining uplink licensed resources that can be mapped after filling the data on LCH1 and LCH2, and it is determined based on the logical channel mapping rules that LCH3 can be mapped to the uplink licensed resources, the data on LCH3 can be mapped to the second remaining uplink licensed resources for filling. That is, the uplink licensed resources can be used to transmit data on LCH1 and LCH2 that conform to the resource mapping rules, and the uplink licensed resources can also be used to transmit data on LCH3 that conforms to the logical channel mapping rules. This enables the uplink licensed resources to be effectively utilized and improves the utilization rate of the uplink licensed resources.

[0110] In one possible implementation of this application embodiment, step 201, where the terminal device maps the logical channel to uplink licensed resources based on resource mapping rules, includes:

[0111] E1. The terminal device maps the logical channel to the uplink authorized resource based on the resource mapping rules and logical channel mapping rules.

[0112] Among them, the logical channel mapping rule is used to indicate the uplink licensed resources that can be mapped to the logical channel.

[0113] In this embodiment, when the terminal device is configured with not only resource mapping rules but also logical channel mapping rules indicating uplink grant resources that can be mapped to logical channels, the terminal device can fill uplink grant resources with data from logical channels that conform to both resource mapping rules and logical channel mapping rules. Specifically, data from logical channels that conform to both resource mapping rules and logical channel mapping rules can be mapped to uplink grant resources for transmission. This can specifically involve mapping data from delay-critical logical channels that conform to both resource mapping rules and logical channel mapping rules to uplink grant resources for transmission, thereby enabling effective utilization of uplink grant resources and improving their utilization rate. If a logical channel only conforms to resource mapping rules but the logical channel mapping rules indicate that the logical channel cannot be mapped to uplink grant resources, then data from the logical channel cannot be mapped to uplink grant resources for transmission.

[0114] Specifically, as shown in Figure 7, when both the resource mapping rule and the logical channel mapping rule are effective, if the terminal device has a first logical channel LCH1, a second logical channel LCH2, and a third logical channel LCH3, and LCH1 and LCH2 contain delay-critical data (i.e., LCH1 and LCH2 are delay-critical logical channels), while LCH3 does not contain delay-critical data (i.e., LCH3 is a non-delay-critical logical channel), the terminal device determines that LCH1 and LCH2 can be mapped to uplink licensed resources according to the resource mapping rule, and determines that LCH1 can be mapped to uplink licensed resources, while LCH2 cannot be mapped to uplink licensed resources. In this case, all data on LCH1 can be mapped to uplink licensed resources for filling, but data on LCH2 cannot be mapped to uplink licensed resources for filling. That is, uplink licensed resources can be used to transmit data on the delay-critical channel LCH1, thereby enabling effective utilization of uplink licensed resources and improving their utilization rate.

[0115] In one possible implementation of this application embodiment, the logical channel includes third indication information, which is used to indicate whether the logical channel can be mapped to uplink licensed resources. Step 201, the terminal device maps the logical channel to uplink licensed resources based on resource mapping rules, including:

[0116] F1. The terminal device maps the logical channel to the uplink authorized resource based on the third indication information and resource mapping rules.

[0117] In this embodiment, different logical channels may include different third indication information. The third indication information included in each logical channel can be used to indicate whether the corresponding logical channel can be mapped to uplink licensed resources for transmission. When the terminal device not only configures resource mapping rules, but also includes third indication information in the logical channel to indicate whether the logical channel can be mapped to uplink licensed resources, and when the third indication information indicates that the logical channel can be mapped to uplink licensed resources configured with resource mapping rules, the terminal device can determine the logical channel that can be mapped to uplink licensed resources based on the third indication information included in the logical channel and the resource mapping rules. That is, it determines the logical channel that conforms to the resource mapping rules and whose included third indication information indicates that it can be mapped to uplink licensed resources, and maps the determined logical channel to the uplink licensed resources for transmission, thereby enabling the uplink licensed resources to be effectively utilized and improving the utilization rate of uplink licensed resources.

[0118] In one possible implementation of this application embodiment, the method further includes:

[0119] G1. When all logical channels do not include delay-critical data, the terminal device maps the logical channels to uplink licensed resources based on the logical channel mapping rules.

[0120] Among them, the logical channel mapping rule is used to indicate the uplink licensed resources that can be mapped to the logical channel.

[0121] In this embodiment, when none of the logical channels in the terminal device contain delay-critical data (i.e., the MAC entity of the terminal device does not contain the delay-critical data to be transmitted), and the terminal device is configured with not only resource mapping rules but also logical channel mapping rules for indicating uplink grant resources that can be mapped to logical channels, the resource mapping rules configured by the terminal device become invalid, and the logical channel mapping rules become effective. The terminal device can map data from logical channels that do not contain delay-critical data to uplink grant resources for filling based on the logical channel mapping rules. In other words, the terminal device can ignore the resource mapping rules and can map data from logical channels that conform to the logical channel mapping rules but do not contain delay-critical data to uplink grant resources for transmission, thereby enabling effective utilization of uplink grant resources and improving their utilization rate. It is understood that the total data volume of logical channels mapped to uplink grant resources should not exceed the transmittable data volume of the uplink grant resources.

[0122] Specifically, as shown in Figure 8, if the terminal device has a first logical channel LCH1, a second logical channel LCH2, and a third logical channel LCH3, and none of LCH1, LCH2, and LCH3 contain delay-critical data (i.e., LCH1, LCH2, and LCH3 are non-delay-critical logical channels), and based on the logical channel mapping rules, it is determined that LCH1 and LCH2 can be mapped to uplink licensed resources, then the terminal device can map the data on LCH1 and LCH2 to the uplink licensed resources for filling. This means the uplink licensed resources can be used to transmit data on LCH1 and LCH2 that conforms to the logical channel mapping rules, thereby enabling effective utilization of the uplink licensed resources and improving their utilization rate.

[0123] In one possible implementation of this application embodiment, the method further includes:

[0124] H1. When all logical channels do not contain delay-critical data, the terminal device maps the logical channels to uplink licensed resources.

[0125] In this embodiment, when no delay-critical data is included in any logical channel of the terminal device (i.e., the MAC entity of the terminal device does not contain the delay-critical data to be transmitted), and the terminal device only has resource mapping rules set, the terminal device can default to the resource mapping rules being invalid. The terminal device can then fill uplink licensed resources with data from any logical channel, meaning it can map any logical channel to uplink licensed resources for transmission. This allows for effective utilization of uplink licensed resources and improves their utilization rate. It is understood that the total data volume of logical channels mapped to uplink licensed resources should not exceed the transmittable data volume of the uplink licensed resources.

[0126] Specifically, as shown in Figure 9, if the terminal device has a first logical channel LCH1, a second logical channel LCH2, and a third logical channel LCH3, and none of LCH1, LCH2, and LCH3 contain delay-critical data (i.e., LCH1, LCH2, and LCH3 are non-delay-critical logical channels), and if the terminal device is only configured with resource mapping rules, then the terminal device can map the data of at least one of the logical channels LCH1, LCH2, and LCH3 to uplink licensed resources for filling. This means the terminal device can utilize uplink licensed resources to transmit data from any one or more of the logical channels LCH1, LCH2, and LCH3, thereby enabling effective utilization of the uplink licensed resources and improving their utilization rate.

[0127] In one possible implementation of the first aspect of this application, when all logical channels do not contain delay-critical data, the resource mapping rule is invalidated. In this embodiment, when all logical channels in the terminal device do not contain delay-critical data, that is, the MAC entity of the terminal device does not contain the delay-critical data to be transmitted, and the terminal device is configured with resource mapping rules, the terminal device can invalidate the resource mapping rules. That is, when mapping data on logical channels to uplink licensed resources, the terminal device can ignore the resource mapping rules, so that the terminal device can use other resource mapping rules or be unrestricted by the resource mapping rules to map data in the logical channels to uplink licensed resources for filling, thereby enabling the uplink licensed resources to be effectively utilized and improving the utilization rate of uplink licensed resources.

[0128] In one possible implementation of this application embodiment, the method further includes:

[0129] J1. The terminal device receives the first instruction information from the network device.

[0130] The first indication information is used to indicate the resource mapping rules.

[0131] In this embodiment, the terminal device can configure resource mapping rules by receiving first indication information from the network device. When the terminal device is not configured with resource mapping rules required to map data in the logical channel to uplink licensed resources, it can configure the unconfigured resource mapping rules by receiving the first indication information from the network device. This allows the terminal device to map data, including delay-critical data, on the logical channel to uplink licensed resources for transmission based on the resource mapping rules indicated by the network device, thereby enabling effective utilization of uplink licensed resources and improving their utilization rate. It is understood that the resource mapping rules indicated by the first indication information may include one or more resource mapping rules.

[0132] In one possible implementation of this application embodiment, the method further includes:

[0133] J2, Receive second instruction information from the network device.

[0134] The second instruction information is used to activate the resource mapping rule indicated by the first instruction information.

[0135] In this embodiment, when a terminal device configures one or more resource mapping rules via first indication information from a network device, it needs to determine the effective resource mapping rule from the configured one or more resource mapping rules. That is, it needs to determine the resource mapping rule required to map data in the logical channel to uplink licensed resources. The terminal device can further determine the activated and effective resource mapping rule from the one or more resource mapping rules indicated in the first indication information based on second indication information from the network device. This allows it to map data, including delay-critical data, on the logical channel to uplink licensed resources for transmission according to the activated and effective resource mapping rule, thereby enabling effective utilization of uplink licensed resources and improving their utilization rate.

[0136] In one possible implementation of this application embodiment, the method further includes:

[0137] K1. The terminal device receives the fourth instruction information from the network device.

[0138] The fourth indication information is used to indicate that the resource mapping rule has failed.

[0139] In this embodiment of the application, the terminal device can receive a fourth instruction from the network device to invalidate the resource mapping rules in the terminal device, so that the terminal device can use other rules or not be restricted by the resource mapping rules to map the data in the logical channel to the uplink licensed resources for filling, thereby enabling the uplink licensed resources to be effectively utilized and improving the utilization rate of the uplink licensed resources.

[0140] 202. The terminal device sends data in the logical channel to the network device through the uplink authorized resources.

[0141] In this embodiment, after mapping a logical channel to uplink licensed resources based on resource mapping rules, the terminal device can transmit data in the logical channel through the uplink licensed resources. Specifically, data in the logical channel can be transmitted to the network device through the uplink licensed resources. By first mapping data, including delay-critical data, on the logical channel to uplink licensed resources based on the set resource mapping rules, and then transmitting the mapped data in the logical channel through the uplink licensed resources, the terminal device can effectively utilize the uplink licensed resources and improve their utilization rate.

[0142] In one possible implementation of this application embodiment, if the data transmitted by the uplink grant resource includes delay-critical data, step 202, in which the terminal device sends the data in the logical channel to the network device through the uplink grant resource, includes:

[0143] L1. If there is a conflict with other resources when transmitting data in the logical channel through uplink grant resources, the data in the logical channel shall be sent to the network device first through uplink grant resources.

[0144] In this embodiment, if a terminal device encounters a conflict with other resources in terms of transmission time or sequence during the transmission of delayed critical data using uplink license resources, the terminal device can prioritize transmitting the data from the uplink license resource because delayed critical data has high latency requirements during data transmission. Specifically, if the terminal device maps delayed critical data or data in a delayed critical logical channel containing delayed critical data to uplink license resources based on resource mapping rules, and a conflict arises between the terminal device and other resources in terms of transmission time or sequence when transmitting the uplink license resource, the terminal device can readjust the priority of the uplink license resource and other resources, making the transmission priority of the uplink license resource higher than other resources. That is, the uplink license for transmitting delayed critical data has the highest priority, and the uplink license resource containing delayed critical data can be transmitted first, thereby ensuring the validity of the delayed critical data transmitted by the uplink license resource. It is understood that if a conflict arises during the transmission of uplink license resources containing delayed critical data with other uplink license resources that also contain delayed critical data, the transmission priority of the uplink license resource can be left unchanged, and the uplink license resource can be transmitted according to a predetermined transmission priority.

[0145] 203. The network device receives data from the terminal device through the logical channel transmitted via the uplink authorized resources.

[0146] In this embodiment of the application, after the terminal device maps the logical channel to the uplink licensed resource based on the resource mapping rule and transmits the data in the logical channel through the uplink licensed resource, the network device can receive the data in the logical channel transmitted by the terminal device through the uplink licensed resource, thereby enabling the uplink licensed resource to be effectively utilized and improving the utilization rate of the uplink licensed resource.

[0147] In one possible implementation of this application embodiment, the method further includes:

[0148] M1, the network device sends the first instruction information to the terminal device.

[0149] The first indication information is used to indicate the resource mapping rules.

[0150] In this embodiment, the network device can configure the resource mapping rules of the terminal device by sending a first indication message to the terminal device. When the terminal device is not configured with resource mapping rules required to map data in the logical channel to uplink licensed resources, the network device can configure the unconfigured resource mapping rules by sending the first indication message. This allows the terminal device to map data, including delay-critical data, on the logical channel to uplink licensed resources for transmission based on the resource mapping rules indicated by the network device, thereby enabling effective utilization of uplink licensed resources and improving their utilization rate. It is understood that the resource mapping rules indicated by the first indication message may include one or more resource mapping rules.

[0151] In one possible implementation of this application embodiment, the method further includes:

[0152] M2, the network device sends a second instruction message to the terminal device.

[0153] The second instruction information is used to activate the resource mapping rule indicated by the first instruction information.

[0154] In this embodiment, when the network device configures one or more resource mapping rules for the terminal device using the first indication information, it needs to indicate the effective resource mapping rule from the configured one or more resource mapping rules, that is, determine the resource mapping rule required to map data in the logical channel to uplink licensed resources. The network device can further indicate the activated and effective resource mapping rule from the one or more resource mapping rules indicated in the first indication information by sending the second indication information, so that the terminal device can map data, including delay-critical data, on the logical channel to uplink licensed resources for transmission according to the activated and effective resource mapping rule, thereby enabling the uplink licensed resources to be effectively utilized and improving the utilization rate of uplink licensed resources.

[0155] In one possible implementation of this application embodiment, the method further includes:

[0156] N1. The network device sends the fourth instruction information to the terminal device.

[0157] The fourth indication information is used to indicate that the resource mapping rule has failed.

[0158] In this embodiment of the application, the network device can send a fourth indication message to the terminal device to indicate that the effective resource mapping rule in the terminal device has become invalid, so that the terminal device can use other rules or not be restricted by the resource mapping rule to map the data in the logical channel to the uplink licensed resource for filling, thereby enabling the uplink licensed resource to be effectively utilized and improving the utilization rate of the uplink licensed resource.

[0159] As illustrated by the foregoing embodiments, compared to the prior art which does not explicitly specify how to utilize uplink license resources for transmitting delay-critical data, resulting in low utilization of uplink license resources and resource waste, this application embodiment aims to improve the utilization of uplink license resources. When the logical channel includes delay-critical data, the terminal device can map the data, including delay-critical data, on the logical channel to uplink license resources for transmission based on pre-configured resource mapping rules. This enables the uplink license resources to be effectively utilized and improves their utilization rate.
