Uplink sending method and apparatus

Abstract

Provided in the embodiments of the present application are an uplink sending method and apparatus. In the embodiments of the present application, uplink data is distributed by means of priorities, and high-priority data and low-priority data are transmitted by means of different channels. In this way, it is ensured that a core network preferentially acquires the high-priority data, such as I-frame data and action data, so as to guarantee lag-free performance in an XR scenario and a cloud game, without affecting the usage experience of a user. Since the low-priority data, such as P frames and B frames, has low timeliness requirements and is sent by means of a secondary channel, the network load can be better balanced, so as to ensure that the high-priority data can still be quickly processed even during network congestion. Thus, multi-channel transmission is utilized to the maximum extent, so that the capacity and coverage range of a communication system are increased, thereby meeting the communication requirements of scenarios with large data traffic, such as an XR scenario or a cloud game scenario.

Description

Uplink sending method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on February 20, 2024, with application number 202410188770.7 and invention name “A method and device for uplink transmission”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a downlink power allocation method and device. Background Art

[0003] With the development of mobile communication technology, the functionality of communication systems is constantly increasing. Specifically, communication systems can provide ultra-reliable low-latency communications (uRLLC), thereby meeting the ultra-high reliability and low latency requirements of wireless communication networks in mission-critical scenarios where network applications require uninterrupted and stable data links.

[0004] The communication system may include network equipment such as base stations, and each base station may support communication with multiple terminal devices. The terminal device may be user equipment (UE). At present, in order to improve the throughput of data transmission, multi-radio dual connectivity (MR-DC) has been introduced in the communication system. MR-DC refers to a technology that allows the UE to communicate with two base stations at the same time when it is in a connected state. Among them, the two base stations include a primary base station and a secondary base station. The primary base station is also called a master node (MN), and the secondary base station is also called a secondary node (SN). The UE makes the main communication connection with the MN, and the SN assists the MN in making the communication connection with the UE. The set of service cells under the control of the MN is defined as the master cell group (MCG). The set of service cells under the control of the SN is defined as the secondary cell group (SCG).

[0005] According to the 3rd Generation Partnership Project (3GPP) specifications, UEs that support MR-DC are usually configured by network equipment. The network equipment has a main channel and a secondary channel for uplink transmission. Among them, the main channel is configured as one of MCG and SCG, and the other is configured as a secondary channel. The main channel is the main transmission channel for transmitting uplink data. In addition, the network also indicates the uplink split threshold to control the UE to distribute uplink data between the main channel and the secondary channel. However, at present, when uplink data is sent on the main channel and / or secondary channel, the uplink coverage of the communication system is weak and the transmission capacity is limited, which affects the performance of the communication system and makes the communication system unsuitable for scenarios with large amounts of transmission data, such as extended display (Extended Reality, XR) and cloud games. How to enhance the uplink coverage and transmission capacity of the communication system has become a key issue of concern in the industry. Summary of the Invention

[0006] The embodiments of the present application provide an uplink transmission method and apparatus for solving the problem that the uplink coverage of a communication system is weak and the transmission capacity is limited, which affects the performance of the communication system.

[0007] In a first aspect, an embodiment of the present application provides an uplink transmission method, which is applied to a terminal device in a multi-air-interface dual-connection MR-DC. The terminal device communicates with a network device through different channels, including a primary channel and an auxiliary channel. The terminal device receives downlink control signaling and determines a first priority channel and a second priority channel. The downlink control signaling carries indication information for determining the first priority channel and the second priority channel of the different channels. The terminal device sends first priority data to the network device through the first priority channel, and sends second priority data to the network device through the second priority channel. Exemplarily, the transmission timeliness of the first priority data is greater than the transmission timeliness of the second priority data.

[0008] Therefore, the embodiment of the present application diverts the uplink data and transmits high-priority data and low-priority data through different channels. This ensures that the core network gives priority to high-priority data, such as I-frame data and action data, to ensure that XR scenes and cloud games are not stuck and do not affect the user experience. Since low-priority data such as P frames and B frames do not have high timeliness requirements, sending them through auxiliary channels can better balance the network load and ensure that high-priority data is processed quickly even when the network is congested. This maximizes the use of multi-channel transmission, improves the capacity and coverage of the communication system, and meets the communication needs of scenes with relatively large data traffic, such as XR scenes or cloud game scenes.

[0009] In one possible implementation, a first downlink control signaling sent by a network device is received, and a primary channel is determined to be a first-priority channel, and an auxiliary channel is determined to be a second-priority channel; the first downlink control signaling carries first channel indication information indicating that the primary channel is the first-priority channel; the first downlink control signaling is radio resource control (RRC) signaling and / or media access control element (MAC) CE signaling; first-priority data is sent to the network device via the primary channel, and second-priority data is sent to the network device via the auxiliary channel. Because the primary channel has higher transmission efficiency and is more reliable than the auxiliary channel, high-priority data is transmitted via the primary channel, and low-priority data is transmitted via the auxiliary channel.

[0010] In another possible implementation, a first downlink control signaling sent by a network device is received, and the main channel is determined to be a first priority channel and the auxiliary channel is determined to be a second priority channel; the first downlink control signaling carries first channel indication information indicating that the main channel is the first priority channel and indicating that the auxiliary channel is the second priority channel; the first downlink control signaling is a radio resource control RRC signaling, and / or a media access control element MAC CE signaling; the first priority data is sent to the network device through the main channel, and the second priority data is sent to the network device through the auxiliary channel.

[0011] In another possible implementation, a second downlink control signaling sent by a network device is received to determine a first priority channel and a second priority channel; the second downlink control signaling carries second channel indication information for determining the first priority channel and the second priority channel; the second downlink control signaling is determined according to the channel quality of the main channel and the channel quality of the auxiliary channel according to a preset period. Channel quality is the ability to transmit data. The ability to transmit data specifically refers to the reliability of transmitted data and the efficiency of transmission. When the base station determines that the ability of the main channel to transmit data is lower than the ability of the auxiliary channel to transmit data, the auxiliary channel can be adjusted to the first priority channel and the main channel to the second priority channel. This ensures that the channel for transmitting first priority data is a highly reliable and efficient transmission channel.

[0012] In another possible implementation, a reporting message is sent indicating that the terminal device supports sending data of different priorities via both the primary and secondary channels, before receiving downlink control signaling. The terminal can support dual-channel, prioritized transmission and send data of varying priorities according to the network device's configuration and requirements, ensuring proper interaction between the network device and the terminal. By adding pre-defined reporting items, terminal device behavior can be further constrained, improving the overall performance of the communication system.

[0013] In another possible implementation, the first priority channel uses a first link adaptation algorithm, and the second priority channel uses a second link adaptation algorithm. The block error rate (BLER) of the second link adaptation algorithm is higher than that of the first link adaptation algorithm, and / or the hybrid automatic repeat request (HARQ) times of the second link adaptation algorithm are lower than those of the first link adaptation algorithm. By adopting a relaxed link adaptation algorithm, the low-priority channel can better adapt to fluctuations and changes in channel conditions without significantly affecting system performance. This strategy can balance the priorities and transmission requirements of different channels, improving the flexibility and efficiency of the entire system.

[0014] Optionally, the first priority data includes intra-frame coded images I frames and motion data in the video frames; the second priority data includes predictive coded images P frames and bidirectional predictive coded images B frames in the video frames.

[0015] On the second aspect, an embodiment of the present application provides an uplink sending method, which is applied to a network device in a multi-air-interface dual-connected MR-DC. The network device configures different channels for the terminal device, and the different channels include a main channel and an auxiliary channel. The network device determines a first priority channel and a second priority channel from the main channel and the auxiliary channel; and sends a downlink control signaling to the terminal device, and the downlink control signaling carries indication information for determining the first priority channel and the second priority channel of the different channels. Then the network device receives the first priority data sent by the terminal device through the first priority channel, and receives the second priority data sent by the terminal device through the second priority channel; and sends the received first priority data and second priority data to the core network. Exemplarily, the transmission time efficiency of the first priority data is greater than the transmission time efficiency of the second priority data.

[0016] Therefore, the embodiment of the present application diverts the uplink data by priority, and transmits high-priority data and low-priority data through different channels. This ensures that the core network gives priority to obtaining high-priority data, such as I-frame data and action data, thereby ensuring that the XR scene and cloud games are not stuck and do not affect the user experience. Since low-priority data such as P frames and B frames do not have high timeliness requirements, they are sent through auxiliary channels, which can better balance the network load and ensure that high-priority data is processed quickly even when the network is congested. This maximizes the use of multi-channel transmission, improves the capacity and coverage of the communication system, and meets the communication needs of scenes with relatively large data traffic, such as XR scenes or cloud game scenes.

[0017] In one possible implementation, a first downlink control signaling is sent to a terminal device, the first downlink control signaling carrying first channel indication information, the first channel indication information being used to indicate that a primary channel is a first priority channel; the first downlink control signaling is radio resource control (RRC) signaling and / or media access control element (MAC) CE signaling; first priority data sent by the terminal device is received via the primary channel, and second priority data sent by the terminal device is received via the secondary channel. Because the primary channel has higher transmission efficiency and is more reliable than the secondary channel, high priority data is transmitted via the primary channel, and low priority data is transmitted via the secondary channel.

[0018] In another possible implementation, a first downlink control signaling is sent to the terminal device, the first downlink control signaling carries first channel indication information, the first channel indication information is used to indicate that the main channel is the first priority channel, and to indicate that the auxiliary channel is the second priority channel; the first downlink control signaling is RRC signaling, and / or MAC CE signaling; the first priority data sent by the terminal device is received through the main channel, and the second priority data sent by the terminal device is received through the auxiliary channel.

[0019] In another possible embodiment, a first priority channel and a second priority channel are determined according to the channel quality of the main channel and the channel quality of the auxiliary channel according to a preset period; a second downlink control signaling is sent to the terminal device, and the second downlink control signaling carries second channel indication information, and the second channel indication information is used to determine the first priority channel and the second priority channel; the second downlink control signaling is RRC signaling, or one of MAC CE signaling. Channel quality, that is, the ability to transmit data. The ability to transmit data specifically refers to the reliability of transmitted data and the efficiency of transmission. When the base station determines that the ability of the main channel to transmit data is lower than the ability of the auxiliary channel to transmit data, the auxiliary channel can be adjusted to the first priority channel and the main channel to the second priority channel. This ensures that the channel for transmitting first priority data is a highly reliable and efficient transmission channel.

[0020] In another possible implementation, if a change in the quality relationship between the primary channel and the secondary channel is detected, a second downlink control signaling message is sent to the terminal device. The second downlink control signaling message carries second channel indication information, which is used to determine the first priority channel and the second priority channel. When the network device detects a change in the quality relationship, it sends the second downlink control signaling message, thereby avoiding technical issues such as data transmission freezes caused by untimely changes to the data transmission channel.

[0021] Optionally, a terminal device may receive a report indicating that the terminal device supports sending data of different priorities via both the primary and secondary channels. The terminal device can support dual-channel, different-priority transmission and send data of different priorities according to the network device's configuration and requirements, thus ensuring proper interaction between the network device and the terminal. By adding pre-set reporting items, terminal behavior can be further constrained, improving the overall performance of the communication system.

[0022] In another possible implementation, the first priority channel uses a first link adaptation algorithm, and the second priority channel uses a second link adaptation algorithm. The block error rate (BLER) of the second link adaptation algorithm is higher than that of the first link adaptation algorithm, and / or the hybrid automatic repeat request (HARQ) times of the second link adaptation algorithm are lower than those of the first link adaptation algorithm. By adopting a relaxed link adaptation algorithm, the low-priority channel can better adapt to fluctuations and changes in channel conditions without significantly affecting system performance. This strategy can balance the priorities and transmission requirements of different channels, improving the flexibility and efficiency of the entire system.

[0023] Optionally, the first priority data includes intra-frame coded images I frames and motion data in the video frames; the second priority data includes predictive coded images P frames and bidirectional predictive coded images B frames in the video frames.

[0024] In a third aspect, an embodiment of the present application provides a communication device, which is applied to a terminal device in an MR-DC. The terminal device uses different channels configured by a network device, where the different channels include a primary channel and a secondary channel. The device includes:

[0025] A first receiving unit is used to receive downlink control signaling to determine a first priority channel and a second priority channel; the downlink control signaling carries indication information for determining the first priority channel and the second priority channel of different channels; a first sending unit is used to send the first priority data to the network device through the first priority channel, and send the second priority data to the network device through the second priority channel.

[0026] In a fourth aspect, an embodiment of the present application provides a communication device, which is applied to a network device in an MR-DC.

It should be noted that in the description of the embodiments of the present application, the words "first" and "second" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0047] The embodiments of the present application are applied to communication systems, which may be 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 may emerge in future communication developments.

[0048] The communication system includes network equipment and terminal equipment. Among them, the network equipment is a device for providing network communication functions, and in some cases it is also called a network element. The network equipment can generally be a base station, a functional unit of a base station, and other ground network equipment. In an embodiment of the present application, in order to improve the throughput of data transmission, the communication system introduces MR-DC. The communication system based on MR-DC is shown in Figure 1. Figure 1 includes a first base station 1, a second base station 2, a core network 3, and a terminal device 4. The terminal device can communicate with the first base station 1 and the second base station 2 at the same time. The first base station 1 and the second base station 2 can be connected, and the access technologies used by the first base station 1 and the second base station 2 can be the same or different. The first base station 1 and the second base station 2 can both be connected to the core network 3. One of the first base station 1 and the second base station 2 is used as an MN, and the other is used as an SN.

[0049] MR-DC specifically includes the following scenarios:

[0050] Evolved universal terrestrial radio access (E-UTRA) and new radio (NR) dual connectivity (E-UTRA-NR dual connectivity (EN-DC), next generation (NG) radio access network (RAN) E-UTRA and NR dual connectivity (NG-RANE-UTRA-NR dual connectivity (NGEN-DC), NR and E-UTRA dual connectivity (NR-E-UTRA Dual Connectivity (NE-DC), and NR-NR dual connectivity (NR-DC).

[0051] In the embodiments provided in the present application, the base station can be any device with wireless transceiver functions, including but not limited to: an evolved base station (NodeB or eNB or e-NodeB, evolutionary Node B) in long term evolution (LTE), a base station (gNodeB or gNB) or a transmission receiving point (TRP) in new radio (NR), a base station of subsequent evolution of 3GPP, an access node in a Wi-Fi system, a wireless relay node, a wireless backhaul node, etc. The base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. The base station can include one or more co-site or non-co-site transmission points (Transmission Reception Point, TRP). The base station can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The base station can communicate with a terminal device, or communicate with the terminal device through a relay station. The terminal device can communicate with multiple base stations of different technologies. For example, the terminal device can communicate with a base station that supports the LTE network, and can also communicate with a base station that supports the 5G network. It can also establish dual connections with a base station that supports the LTE network and a base station that supports the 5G network.

[0052] In the embodiments provided herein, the terminal device 4 may be in various forms providing XR technology or cloud gaming, such as a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, 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 sometimes referred to as a terminal device, user equipment (UE), an access terminal device, an in-vehicle terminal device, an industrial control terminal device, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal device, a mobile device, a UE terminal device, a terminal device, a wireless communication device, a UE agent, or a UE device. The terminal device may also be a fixed terminal device or a mobile terminal device.

[0053] Figure 2 shows a schematic diagram of a protocol architecture for network devices based on MR-DC. The protocol architecture shown in Figure 2 includes a primary channel and a secondary channel. The primary channel is configured as either an MCG or SCG, and the secondary channel is configured as the other of the MCG and SCG. It should be noted that the primary channel refers to the primary data transmission channel in a communication system. Compared to the secondary channel, the primary channel has higher bandwidth and lower latency, enabling efficient and reliable data transmission. Uplink data transmitted on the primary channel has low latency and high reliability.

[0054] Figure 2 configures the primary channel as the first CG and the secondary channel as the second CG. The first CG is sent to the packet data convergence protocol (PDCP) layer via the first media access control (MAC) layer and the first radio link control protocol (RLC) layer. The PDCP layer processes the received data and sends the processed data to the core network 3 via the service data adaptation protocol (SDAP) layer. The second CG is sent to the PDCP layer via the second MAC layer and the second RLC layer. The PDCP layer processes the received data, such as replay, decryption, and integrity verification, and sends the processed data to the core network 3 via the SDAP layer.

[0055] During uplink data transmission, when the flow of uplink data is less than or equal to the threshold value, the network device instructs the terminal device to always send uplink data on the main channel. If the flow of uplink data is greater than the threshold value, the uplink data exceeding the threshold value is transmitted by the auxiliary channel. Exemplary explanation: suppose the threshold value is 8M. If the uplink data is 4M, it is less than 8M, then the network device instructs the terminal device to send uplink data on the main channel. If the uplink data is 12M, 8M of uplink data is sent through the main channel, and the other 4M of uplink data is sent through the auxiliary channel.

[0056] However, the above-mentioned method of shunting transmission based on uplink data exceeding the threshold value cannot maximize the use of multi-channel transmission, resulting in limited transmission capacity and coverage of the communication system, affecting the communication performance of the communication system. For example, in scenarios with relatively large amounts of uplink data such as XR or cloud gaming, part of the uplink data is transmitted through the main channel, and the other part of the uplink data is transmitted through the auxiliary channel. This will cause the I-frame data and action data in the video frame data to be unable to be effectively transmitted to the core network, causing the XR or cloud gaming interface to freeze. Therefore, how to enhance the uplink coverage and transmission capacity of the communication system has become a key issue of concern in the industry.

[0057] In view of the above problems, an embodiment of the present application provides an uplink sending method, which performs diversion by priority, that is, data of different priorities go through different channels, thereby maximizing the use of multi-channel transmission, improving the transmission capacity and coverage of the communication system, and meeting the communication needs of scenarios with relatively large data traffic, such as XR scenarios or cloud gaming scenarios.

[0058] The uplink sending method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0059] First, analyze the important data of XR scenarios or cloud gaming scenarios.

[0060] The data in XR scenes or cloud gaming scenes includes action data and video frame data. Video frame data includes intra-coded picture (I) frames, forward reference (P) frames, and bidirectionally predicted picture (B) frames. See Figure 3, which shows a schematic diagram of the transmission encoding of video frame data.

[0061] I-frames, also known as keyframes or independent frames, consider only their own data during encoding, independent of information from other frames. They store complete image data and serve as a reference point in the encoding sequence. During the encoding process, each I-frame serves as a key point, used to recover the complete image data.

[0062] P-frames are predictively coded frames that rely on the previous I-frame for encoding. They only store the differences from the previous I-frame and are therefore typically smaller than I-frames. P-frames require a complete I-frame to be correctly decoded.

[0063] B frames are bidirectionally predictively coded, relying on the preceding I or P frame and the following I or P frame. Figure 3 shows the differences between a B frame, the preceding P frame, and the following I frame. Decoding a B frame requires reference to both the preceding and following reference frames. For Figure 3, decoding a B frame requires considering both the preceding P frame and the following I frame.

[0064] In summary, I-frames are more important than P-frames and B-frames and require priority processing. Specifically, P-frame and B-frame bit errors will not cause the video display interface to freeze, but I-frame bit errors will cause the video display interface to freeze. Therefore, in this embodiment of the application, I-frames are set as first-priority data, and P-frames and B-frames are set as second-priority data, with first-priority data having a higher priority than second-priority data.

[0065] In addition, in XR scenarios or cloud gaming scenarios, motion data is also extremely important. Motion data, such as body language, gestures, and body posture, is important data for improving user experience, ensuring natural and intuitive interactions, and achieving a high-quality immersive experience. In the embodiments of this application, data such as motion data can also be set as first-priority data.

[0066] In addition, those skilled in the art may also determine some other data as first priority data and second priority data as needed. This application does not specifically limit the specific content of the first priority data and the second priority data.

[0067] The channel priority configuration method provided in the embodiments of the present application is described below in conjunction with different embodiments.

[0068] Example 1

[0069] The following describes a method for configuring channel priority.

[0070] In an embodiment of the present application, the base station configures the main channel as the first priority channel and the auxiliary channel as the second priority channel. The first priority channel sends first priority data, and the second priority channel sends second priority data. Thus, high priority data is sent through the main channel and low priority data is sent through the auxiliary channel. When the amount of uplink data is large, low priority data can be transmitted in the remaining bandwidth on the basis of ensuring the reliability and real-time performance of high priority data transmission, thereby maximizing the use of multi-channel resources, improving the transmission capacity and coverage of the communication system, and meeting the communication needs of scenes with relatively large data traffic, such as XR scenes or cloud gaming scenes.

[0071] In an embodiment of the present application, the base station may configure the primary channel and the secondary channel by issuing a first downlink control signaling. The first downlink control signaling carries first channel indication information, and the first channel indication information is used to indicate that the primary channel is the first priority channel. Alternatively, the first channel indication information carried in the first downlink control signaling is used to indicate that the primary channel is the first priority channel and that the secondary channel is the second priority channel.

[0072] In one example, the base station may configure the primary channel as the first priority channel through radio resource control (RRC). Specifically, the base station may configure the priority of the relevant channel through RRC signaling. For example, when configuring multiple RLC fields, the primary channel is configured as the first priority channel in the following manner.

[0073] ul-DataSplitPriority is the first channel indication information carried in the RRC signaling. When BOOLEAN is assigned a value of 1, it indicates that the main channel is the first priority channel. If BOOLEAN is assigned a value of 0, it indicates that when the main channel is activated, the main channel does not send the first priority data according to the priority. Or when BOOLEAN is assigned a value of 0, it indicates that the main channel is the first priority channel. If BOOLEAN is assigned a value of 1, it indicates that the main channel is activated, and the main channel does not send the first priority data according to the priority. By assigning BOOLEAN of ul-DataSplitPriority, the configuration of the main channel can be realized when configuring RLC. The operation is simple and easy to implement.

[0074] In another example, when the base station configures the primary channel as the first priority channel in RRC, the base station may directly activate the primary channel as the first priority channel, or the primary channel may have the function of a first priority channel but the function has not yet been activated. In this case, the function of sending high priority data on the primary channel may be activated through a MAC control element (CE).

[0075] Specifically, in one possible manner, MAC CE multiplexes a known MAC CE. The known MAC CE refers to the scheduling activation / deactivation (also known as Duplication Activation / Deactivation) MAC CE, and its corresponding LCID value is 56. The structure of MAC CE includes the N1 field and the N2 field, wherein the N1 field is the primary channel field and the N2 is the secondary channel field. When the N1 field is filled with 1, it indicates that the primary channel is activated to send the first priority data. When the N1 field is filled with 0, it indicates that the primary channel is deactivated and the first priority data is no longer sent according to the priority. When the N2 field is filled with 1, it indicates that the secondary channel is activated to send the second priority data. When the N2 field is filled with 0, it indicates that the secondary channel is deactivated and the second priority data is no longer sent.

[0076] In another possible embodiment, the MAC CE is a newly defined MAC CE. The newly defined MAC CE includes the N1 field for the primary channel and the N2 field for the secondary channel. When the N1 field is filled with 1, the primary channel is activated to send first-priority data. When the N1 field is filled with 0, the primary channel is deactivated and no longer sends first-priority data according to priority. When the N2 field is filled with 1, the secondary channel is activated to send second-priority data. When the N2 field is filled with 0, the secondary channel is deactivated and no longer sends second-priority data.

[0077] Based on the above-mentioned primary channel configuration method, an embodiment of the present application provides an implementation method for uplink transmission. See Figure 4, which is a flowchart of an implementation method for uplink transmission provided by an embodiment of the present application. The method specifically includes the following steps:

[0078] S41: The terminal device receives a first downlink control signaling sent by the network device and determines a first priority channel and a second priority channel.

[0079] S42: The terminal device sends the first priority data to the network device through the main channel.

[0080] The terminal device sends the first priority data to the core network on the network device side through the main channel. Specifically, the first priority data is sent to the PDCP layer through the first CG, the first MAC layer, and the first RLC layer. The PDCP layer processes the received data and sends the processed data to the core network through the SDAP layer.

[0081] S43: The terminal device sends the second priority data to the network device through the auxiliary channel.

[0082] The terminal device sends the second priority data to the PDCP layer through the second CG, the second MAC layer, and the second RLC layer. The PDCP layer processes the received data and sends the processed data to the core network on the network device side through the SDAP layer.

[0083] In one possible scenario, the primary channel is first activated, making the primary channel the configured primary channel, and the first priority data is sent to the core network through the configured channel. After the primary channel is activated for a preset period of time, the secondary channel is activated and the second priority data is sent through the secondary channel.

[0084] In another possible case, the primary channel and the secondary channel are activated at the same time, and the terminal device simultaneously sends the first priority data to the core network through the configured primary channel and sends the second priority data to the core network through the secondary channel.

[0085] It should be noted that the execution order of step S42 and step 43 is not limited. For example, step S43 may be executed first, then step S42, or step S43 and step S42 may be executed simultaneously. Specific steps can be adjusted by those skilled in the art as needed.

[0086] Therefore, the embodiment of the present application transmits high-priority data through the main channel and low-priority data through the auxiliary channel. This ensures that the core network gives priority to obtaining high-priority data, such as I-frame data and action data, thereby ensuring that XR scenes and cloud games are not stuck and do not affect the user experience. Since low-priority data such as P frames and B frames do not have high timeliness requirements, sending them through the auxiliary channel can better balance the network load and ensure that high-priority data is processed quickly even when the network is congested. This maximizes the use of multi-channel transmission, improves the capacity and coverage of the communication system, and meets the communication needs of scenes with relatively large data traffic, such as XR scenes or cloud game scenes.

[0087] Example 2

[0088] The following describes another way to configure channel priority.

[0089] The base station dynamically adjusts the priorities of the primary channel and the secondary channel according to the channel state information (CSI) of different uplink paths or the channel state information such as the supplementary uplink (SUL).

[0090] Channel status information describes the channel quality of the primary and secondary channels. This information can include CSI or information such as whether a SUL has been added. Using this information, the base station can determine the channel quality of the primary and secondary channels, specifically their data transmission capabilities. Data transmission capabilities specifically refer to data transmission reliability and efficiency. If the base station determines that the data transmission capability of the primary channel is lower than that of the secondary channel, it can configure the secondary channel as a first-priority channel and the primary channel as a second-priority channel. This ensures that the channel transmitting first-priority data is a highly reliable and efficient transmission channel.

[0091] In this embodiment of the present application, the base station can dynamically adjust the priority of the primary channel and the secondary channel by issuing a second downlink control signaling. The second downlink control signaling carries second channel indication information, and the second channel indication information is used to determine the first priority channel and the second priority channel.

[0092] In one example, the base station notifies the terminal device of the new priority setting via RRC signaling. The RRC signaling includes parameters such as the primary and secondary channel priority. After receiving the RRC signaling from the base station, the terminal device dynamically adjusts the uplink data transmission method and priority according to the base station's instructions to match the base station's configuration.

[0093] In another example, the base station switches the priority of the primary and secondary channels through MAC CE signaling. The base station notifies the terminal device of the new priority settings through MAC CE signaling. The MAC CE signaling includes parameters for the primary and secondary channels' priorities. After receiving the MAC CE signaling from the base station, the terminal device dynamically adjusts the uplink data transmission method and priority based on the base station's instructions to match the base station's configuration.

[0094] In one possible approach, a MAC CE reuses a known MAC CE. The known MAC CE refers to the scheduling activation / deactivation (also known as duplication activation / deactivation) MAC CE, whose corresponding LCID value is 56. For the MAC CE structure, when the N1 field is filled with 1, the primary channel is the first priority channel; when the N1 field is filled with 0, the primary channel is the second priority channel. When the N2 field is filled with 1, the secondary channel is the first priority channel; when the N2 field is filled with 0, the secondary channel is the second priority channel.

[0095] In another possible embodiment, the MAC CE is a newly defined MAC CE. The newly defined MAC CE includes an N1 field and an N2 field. The N1 field represents the primary channel, and the N2 field represents the secondary channel. When the N1 field is filled with 1, it indicates that the primary channel is the first priority channel; when the N1 field is filled with 0, it indicates that the primary channel is the second priority channel. When the N2 field is filled with 1, it indicates that the secondary channel is the first priority channel; when the N2 field is filled with 0, it indicates that the secondary channel is the second priority channel.

[0096] Based on the dynamic adjustment of the priority channels of the primary channel and the secondary channel, the embodiment of the present application also provides another implementation method of uplink transmission. See Figure 5, which is an interaction diagram of another implementation method of uplink transmission provided by the embodiment of the present application. The method specifically includes the following steps:

[0097] S51: The base station monitors the channel quality of the primary channel and the channel quality of the secondary channel.

[0098] The base station monitors the CSI of the primary channel and the secondary channel and / or whether the SUL is added in real time, and determines the channel quality of the primary channel and the channel quality of the secondary channel according to the CSI and / or whether the SUL is added.

[0099] S52: The base station determines the priority channels of the primary channel and the secondary channel according to the channel quality of the primary channel and the channel quality of the secondary channel.

[0100] If the base station determines that the channel quality of the primary channel is not less than that of the secondary channel, the primary channel is adjusted to the first priority channel and the secondary channel is adjusted to the second priority channel. If the base station determines that the channel quality of the primary channel is less than that of the secondary channel, the primary channel is adjusted to the second priority channel and the secondary channel is adjusted to the first priority channel.

[0101] S53: The base station sends the priority channels of the primary channel and the secondary channel to the terminal device through the second downlink control signaling.

[0102] In one possible implementation, the base station sends the priority channels of the primary channel and the auxiliary channel to the terminal device through the second downlink control signaling based on a preset period, such as 1ms or 5ms. Alternatively, the base station detects a change in the quality relationship between the channel quality of the primary channel and the channel quality of the auxiliary channel and directly sends the second downlink control signaling.

[0103] The second downlink control signaling may be RRC signaling or MAC CE signaling.

[0104] For example, if the first priority channel is a secondary channel and the second priority channel is a primary channel, the following signaling may be sent to the terminal device: ul-HighPriority ENUMERATED{secondary,primary}, where secondary is the secondary channel and primary is the primary channel.

[0105] S54: The terminal device determines a first priority channel and a second priority channel.

[0106] The specific implementation is the same as step S41 and will not be discussed here.

[0107] S55: The terminal device sends the uplink data to the network device according to the received priority channels of the primary channel and the secondary channel.

[0108] Exemplarily, if the main channel received by the terminal device from the base station is the first priority channel and the auxiliary channel is the second priority channel, the first priority data is sent to the core network through the main channel, and the second priority data is sent to the core network through the auxiliary channel. If the main channel received by the terminal device from the base station is the second priority channel and the auxiliary channel is the first priority channel, the second priority data is sent to the core network through the main channel, and the first priority data is sent to the core network through the auxiliary channel.

[0109] Therefore, the embodiment of the present application ensures that the channel for transmitting first priority data is a highly reliable and efficient transmission channel by dynamically adjusting the priority channels of the main channel and the auxiliary channel.

[0110] Example 3

[0111] The following describes another way to configure channel priority.

[0112] The terminal device has UE reporting capability, such as splitDRB-withUL-different-priority.

[0113] Specifically, before the base station configures the first priority channel and the second priority channel, the terminal device sends reporting information to the network device, where the reporting information is used to indicate that the terminal device can support dual-channel different priority transmission modes.

[0114] After receiving the reported information, the base station determines that the terminal device has the ability to support dual-channel different priority transmission modes, and configures the terminal device with a dual-channel transmission mode of a first priority channel and a second priority channel.

[0115] In one example, when the terminal device does not have the ability to support dual-channel different priority transmission, the terminal device can send non-support information to the network device. After receiving the non-support information, the network device no longer performs the operation of determining the first priority channel and the second priority channel.

[0116] In another example, when the terminal device does not have the ability to support dual-channel different priority sending methods, the terminal device does not send reporting information to the network device. After the network device does not receive the reporting information within a preset time, it no longer performs the operation of determining the first priority channel and the second priority channel.

[0117] Therefore, by adding preset reporting items before configuration, the embodiment of the present application can better constrain the behavior of terminal devices and network devices, avoid network devices from performing subsequent operations such as determining the first priority channel and the second priority channel, and improve the overall performance of the communication system.

[0118] Example 4

[0119] In addition, an embodiment of the present application also provides another implementation method for configuring channel priority.

[0120] When configuring the priorities of the primary and secondary channels, the base station uses different link adaptation methods for each channel. The first-priority channel uses the first link adaptation algorithm, while the second-priority channel uses the second link adaptation algorithm. The first link adaptation algorithm has a higher error rate for handling transmission errors than the second link adaptation algorithm. In other words, the lower-priority channel uses a relaxed link adaptation algorithm to accommodate different channel conditions and transmission requirements.

[0121] As shown in FIG2 , the primary channel and the secondary channel each have their own MAC entity. The primary channel corresponds to the first MAC, and the secondary channel corresponds to the second MAC.

[0122] In one example, if the primary channel is a high-priority channel and transmits high-priority data, and the secondary channel is a low-priority channel and transmits low-priority data, the primary channel needs to adopt a stricter link adaptation algorithm. For example, the block error rate (BLER) can be controlled at a lower level, such as 10%, and the number of hybrid automatic repeat requests (HARQ) is set to a maximum of 3 retransmissions. The secondary channel needs to adopt a relaxed link adaptation algorithm. For example, the BLER can be controlled at 15%, and the HARQ is set to a maximum of 2 retransmissions.

[0123] In another example, if the primary channel is a low-priority channel and transmits low-priority data, and the secondary channel is a high-priority channel and transmits high-priority data. In this case, the secondary channel needs to adopt a stricter link adaptation algorithm. For example, the block error rate (BLER) can be controlled at a lower level, such as 10%, and the number of hybrid automatic repeat requests (HARQ) is set to a maximum of 3 retransmissions. The primary channel needs to adopt a relaxed link adaptation algorithm. For example, the BLER can be controlled at 15%, and the HARQ can be set to a maximum of 2 retransmissions.

[0124] As a result, the network equipment controls the BLER of the low-priority channel at a higher level, which can reduce the requirements for transmission quality and allow data transmission to be maintained even when the channel conditions are poor.

[0125] HARQ is a mechanism used to improve data transmission reliability. By reducing the number of HARQ cycles for low-priority channels, network devices can reduce the need for retransmissions, thereby reducing transmission latency and increasing system capacity. By employing a relaxed link adaptation algorithm, low-priority channels can better adapt to fluctuating and changing channel conditions without significantly impacting system performance. This strategy balances the priorities and transmission requirements of different channels, improving overall system flexibility and efficiency.

[0126] In addition, an embodiment of the present application provides a communication device applied to a terminal device in MR-DC, wherein the terminal device uses different channels configured by a network device, wherein the different channels include a primary channel and a secondary channel.
