Description

Technical Field

[0001] This application relates to the field of communications, and more particularly, to a communication method and a communication device. Background Art

[0002] To meet people's needs for new media services, extended reality (XR) services are introduced in the fifth generation (5G) mobile communication technology. XR is a general term for immersive technologies such as augmented reality (AR), virtual reality (VR), and mixed reality (MR). XR services pose higher requirements for large capacity and low latency. To meet the needs of XR services, the 3rd generation partnership project (3GPP) standard protocol is currently discussing how to enhance the priority of logical channels (LCH), but there is no clear solution yet. Summary of the Invention

[0003] In view of this, this application provides a communication method, a communication device, a chip system, a computer-readable storage medium, a computer program product, and a communication system. By dynamically adjusting the remaining time threshold of a logical channel according to the uplink channel quality, a UE determines the priority of a first logical channel based on the first remaining time threshold. For example, the priority of the first logical channel is increased, thereby enhancing the network's support for low-latency services.

[0004] In a first aspect, a communication method is provided. This method can be executed by a UE, or by a component (such as a circuit, a chip, or a chip system, etc.) configured in the UE, or by a logical module or software that can implement all or part of the UE functions. This application does not limit this.

[0005] Specifically, the method includes: the UE obtains a first remaining time threshold, where the first remaining time threshold is determined according to the channel quality of the uplink channel; then determines the priority of a first logical channel according to the first remaining time threshold; and finally uses transmission resources to transmit the data to be transmitted on the first logical channel, where the transmission resources are allocated according to the priority of the first logical channel. Compared with using a fixed remaining time threshold, in the embodiments of this application, the first remaining time threshold is dynamically adjusted according to the channel quality of the uplink channel, and the optimal scheduling of resources is achieved by sensing the channel quality, which helps to improve the transmission reliability of low-latency services and also helps to improve resource utilization.

[0006] Optionally, the data to be transmitted of the first service is included in the first logical channel. The first service refers to a service with high latency requirements (such as XR service).

[0007] In the embodiments of the present application, whether the channel quality is good or bad, the remaining time threshold can be adjusted in combination with the channel quality. Then, when it is monitored that the remaining time of the data to be transmitted in the first logical channel in the logical channel is less than or equal to the first remaining time threshold, the extra priority of the first logical channel is triggered, or in other words, the priority of the first logical channel is increased. In this way, transmission resources are preferentially allocated to the first logical channel, which can ensure the smooth transmission of the data to be transmitted in the first logical channel.

[0008] The embodiments of the present application do not limit the specific manner in which the UE obtains the first remaining time threshold. Optionally, the first remaining time threshold is directly sent by the network device to the UE; or, the first remaining time threshold is determined by the UE according to the channel quality of the uplink channel and the first mapping table. The first mapping table refers to the mapping relationship between the channel quality and the remaining time threshold. The following will be described separately.

[0009] In a possible implementation manner, the UE receives a first signaling from the network device, and the first signaling includes the first remaining time threshold, where the first remaining time threshold is determined by the network device according to the channel quality of the uplink channel.

[0010] Therefore, the network device directly sends the first remaining time threshold to the UE. This method saves the process for the UE to determine the first remaining time threshold. For example, it omits the process of querying the remaining time threshold in the mapping table, and the implementation manner is relatively simple. Moreover, since the first remaining time threshold is determined according to the channel quality of the uplink channel, and the channel quality result measured by the network device for the uplink channel is more accurate, that is, the channel quality result measured by the network device can accurately reflect the actual situation of the uplink channel, the determined first remaining time threshold is also more appropriate.

[0011] In another possible implementation manner, the UE determines the channel quality of the uplink channel; according to the correspondence between the first remaining time threshold and the first channel quality interval and the channel quality of the uplink channel, the first remaining time threshold is determined, and the channel quality of the uplink channel is within the first channel quality interval. Therefore, the UE can autonomously determine the first remaining time threshold based on the correspondence between the first remaining time threshold and the first channel quality interval, avoiding the UE's dependence on the real-time scheduling instructions of the network device.

[0012] It can be understood that the correspondence between the first remaining time threshold and the first channel quality interval can be predefined by the protocol or sent by the network device to the UE.

[0013] The embodiments of the present application do not specifically limit the representation form or corresponding manner of the correspondence between the first remaining time threshold and the first channel quality interval. For example, the correspondence between the first remaining time threshold and the first channel quality interval can be a one-to-one relationship or a one-to-many relationship. For another example, the correspondence between the first remaining time threshold and the first channel quality interval is presented in the form of a mapping table.

[0014] Optionally, before determining the first remaining time threshold according to the correspondence between the first remaining time threshold and the first channel quality interval and the channel quality of the uplink channel, the method further includes: The UE receives a second signaling from the network device, and the second signaling includes the first mapping table, and the first mapping table at least includes the correspondence between the first remaining time threshold and the first channel quality interval. Therefore, the network device sends the first mapping table to the UE, and then the UE looks up the corresponding remaining time threshold in the first mapping table. In this way, the UE is avoided from relying on the real-time scheduling instructions of the network device.

[0015] Optionally, the UE determines the channel quality of the uplink channel, including: measuring the channel quality of the downlink channel; determining the channel quality of the uplink channel according to the channel quality of the downlink channel. Since the UE determines the uplink channel quality by using channel reciprocity, the overhead of uplink measurement is reduced.

[0016] In a possible implementation manner, the value of the first remaining time threshold is negatively correlated with the channel quality of the uplink channel. That is, the better the channel quality of the uplink channel, the smaller the value of the first remaining time threshold; the worse the channel quality of the uplink channel, the larger the value of the first remaining time threshold. Therefore, by using the channel quality of the uplink channel as a key parameter for determining the remaining time threshold, the priority of each logical channel can be flexibly triggered, and fine-grained resource allocation can be realized to meet the low-latency requirements of services.

[0017] Exemplarily, the value of the first remaining time threshold being negatively correlated with the channel quality of the uplink channel includes: when the channel quality value of the uplink channel is in the first channel quality interval, the first remaining time threshold is the first threshold; when the channel quality value of the uplink channel is in the second channel quality interval, the first remaining time threshold is the second threshold; when the channel quality value of the uplink channel is in the third channel quality interval, the first remaining time threshold is the third threshold; where the first channel quality interval, the second channel quality interval, and the third channel quality interval represent gradually better channel qualities in sequence; and the values of the first threshold, the second threshold, and the third threshold decrease in sequence.

[0018] The embodiments of the present application do not specifically limit the signaling or message type used by the network device to send the first remaining time threshold or the first mapping table to the UE.

[0019] Optionally, the first signaling or the second signaling is any one of the following signaling: Medium Access Control Control Element (MAC CE) signaling, Radio Resource Control (RRC) signaling, and Downlink Control Information (DCI).

[0020] In a possible implementation manner, the UE determines the priority of the first logical channel according to the first remaining time threshold, including: when the remaining time of the data to be transmitted on the first logical channel is less than or equal to the first remaining time threshold, determining the priority of the first logical channel from the first priority to the second priority (i.e., the additional priority), where the second priority is higher than the first priority, and the first priority is the initial priority of the first logical channel. Therefore, when the remaining time reaches (for example, the remaining time is equal to the first remaining time threshold) the first remaining time threshold, the UE triggers the additional priority of the first logical channel, or in other words, raises the priority of the first logical channel, so that the transmission resources are preferentially allocated to the first logical channel, which can ensure the smooth transmission of the data to be transmitted on the first logical channel.

[0021] Optionally, the method further includes: the UE receives the updated first mapping table sent by the network device; and determines the priority of the first logical channel according to the updated first mapping table and the channel quality of the uplink channel. Therefore, by receiving the updated first mapping table sent by the network device, the UE can determine the remaining time threshold based on the latest first mapping table, and thus determine the priority of the logical channel.

[0022] The embodiments of the present application do not specifically limit the standard parameters (or quantization metrics) of the channel quality. Optionally, the channel quality of the uplink channel is characterized by one or more of the following parameters: Reference Signal Received Power (RSRP), Signal-to-Interference-plus-Noise Ratio (SINR), and Reference Signal Received Quality (RSRQ).

[0023] In a second aspect, a communication method is provided. This method can be executed by a network device, or can also be executed by a component (such as a circuit, a chip, or a chip system, etc.) configured in the network device, or can also be implemented by a logic module or software that can implement all or part of the functions of the network device. The present application does not limit this.

[0024] Specifically, the method includes: the network device determines a first remaining time threshold or a first mapping table by measuring the channel quality of the uplink channel; and sends the first remaining time threshold or the first mapping table to the UE, specifically including: the network device sends a first signaling to the user equipment UE, the first signaling includes the first remaining time threshold, where the first remaining time threshold is determined by the network device according to the channel quality of the uplink channel; or sends a second signaling to the UE, the second signaling includes the first mapping table, the first mapping table at least includes the correspondence between the first remaining time threshold and the first channel quality interval, and the first mapping table is determined by the network device according to the channel quality of the uplink channel, so that the UE determines the priority of the logical channel based on the first remaining time threshold. Compared with using a fixed remaining time threshold, in the embodiment of the present application, the first remaining time threshold is dynamically adjusted according to the channel quality of the uplink channel, and the optimal scheduling of resources is realized by sensing the channel quality, which helps to improve the transmission reliability of low-latency services and also helps to improve the resource utilization rate.

[0025] The embodiment of the present application does not specifically limit the type of signaling or message used by the network device to send the first remaining time threshold or the first mapping table to the UE.

[0026] In a possible implementation manner, the first signaling or the second signaling is any one of the following signaling: media access control control element MAC CE signaling, radio resource control RRC signaling, and downlink control information DCI.

[0027] In a possible implementation manner, the value of the first remaining time threshold is negatively correlated with the channel quality of the uplink channel. For the relationship between the channel quality and the first remaining time threshold, reference can be made to the description of the first aspect. For the sake of brevity, it will not be elaborated here.

[0028] Optionally, the value of the first remaining time threshold being negatively correlated with the channel quality of the uplink channel includes: when the channel quality value of the uplink channel is in the first channel quality interval, the first remaining time threshold is the first threshold; when the channel quality value of the uplink channel is in the second channel quality interval, the first remaining time threshold is the second threshold; when the channel quality value of the uplink channel is in the third channel quality interval, the first remaining time threshold is the third threshold; where the first channel quality interval, the second channel quality interval, and the third channel quality interval represent gradually better channel quality in sequence; and the values of the first threshold, the second threshold, and the third threshold decrease in sequence.

[0029] Optionally, the method further includes: the network device updates the first mapping table based on a first period, and sends the updated first mapping table to the UE. Therefore, the network device can update the first mapping table periodically, so as to adjust the first mapping table according to the actual condition of the uplink channel, and send the updated first mapping table to the UE, so that the UE can determine the remaining time threshold based on the latest first mapping table, and thus determine the priority of the logical channel.

[0030] Optionally, the channel quality of the uplink channel is characterized by one or more of the following parameters: reference signal received power (RSRP), signal-to-interference-plus-noise ratio (SINR), and reference signal received quality (RSRQ).

The access network device and / or the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on airplanes, balloons, and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the access network device and the terminal. The access network device and the terminal device can be deployed in the same scenario or different scenarios. For example, the access network device and the terminal device are both deployed on land; or, the access network device is deployed on land and the terminal device is deployed on the water surface, etc., and will not be listed one by one.

[0080] In the embodiments of the present application, each element in the communication system can be regarded as a network element in the communication system. For example, Figure 1The helicopter or drone 120i therein can be configured as a mobile access network device. For the terminal devices 120j accessing the radio access network 100 through 120i, the helicopter or drone 120i is an access network device; but for the access network device 110a, 120i is a terminal device, that is, the communication between 110a and 120i is through the radio air interface protocol. The communication between 110a and 120i can also be through the interface protocol between access network devices. At this time, relative to 110a, 120i is also an access network device. Therefore, both access network devices and terminal devices can be uniformly referred to as communication devices. Figure 1 The 110a and 110b therein can be referred to as communication devices with the functions of access network devices. Figure 1 The 120a - 120k therein can be referred to as communication devices with the functions of terminal devices.

[0081] In this application, the device for implementing the functions of a network device can be a network device or a device capable of supporting the network device to implement such functions, such as a processor, a circuit, a chip, or a chip system, etc. This device can be installed in the network device or used in connection with the network device. Alternatively, the device for implementing the functions of a network device can also be a control subsystem containing the functions of a network device. For example, the control subsystem containing the functions of an access network device can be a control center in scenarios applicable to terminals such as smart grids, industrial control, intelligent transportation, or smart cities. In the technical solution provided in this application, the case where the device for implementing the functions of a network device is a network device is taken as an example to describe the technical solution provided in this application.

[0082] In this application, the device for implementing the functions of a terminal device can be a terminal device or a device capable of supporting the terminal device to implement such functions, such as a processor, a circuit, a chip, a chip system, etc. This device can be installed in the terminal device or used in connection with the terminal device. In the technical solution provided in this application, the case where the device for implementing the functions of a terminal device is a UE is taken as an example to describe the technical solution provided in this application.

[0083] The communication between the access network device and the terminal device can follow a certain protocol layer structure. Exemplarily, the protocol layer structure can include a control plane protocol layer structure and a user plane protocol layer structure. For example, the control plane protocol layer structure can include at least one of the following: radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access control (MAC) layer, or physical (PHY) layer, etc. For example, the user plane protocol layer structure can include at least one of the following: service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer, or physical layer, etc.

[0084] As Figure 2 shown, the access network device can include a CU and a DU. This design can be referred to as the separation of CU and DU. Multiple DUs can be centrally controlled by one CU. As an example, the interface between the CU and the DU is called the F1 interface. Among them, the control plane (CP) interface can be F1-C, and the user plane (UP) interface can be F1-U. The embodiments of the present application do not limit the specific names of each interface. The CU and the DU can be divided according to the protocol layers of the wireless network: for example, the functions of the PDCP layer and the upper protocol layers (such as the RRC layer and the SDAP layer, etc.) are set in the CU, and the functions of the protocol layers below the PDCP layer (such as the RLC layer, the MAC layer, and the PHY layer, etc.) are set in the DU; or for another example, the functions of the protocol layers above the PDCP layer are set in the CU, and the functions of the PDCP layer and the lower protocol layers are set in the DU, without limitation.

[0085] The above division of the processing functions of the CU and the DU according to the protocol layers is only an example, and it can also be divided in other ways. For example, the CU or the DU can be divided into functions with more protocol layers, or for another example, the CU or the DU can be divided into partial processing functions of the protocol layers. For example, some functions of the RLC layer and the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements, such as dividing by delay, setting the functions that need to meet the delay requirements in the DU, and setting the functions that do not need to meet the delay requirements in the CU.

[0086] Optionally, the CU can have one or more functions of the core network.

[0087] Optionally, the radio unit (RU) of the DU can be remotely deployed. The RU has radio frequency functions. Exemplarily, the DU and the RU can be divided at the PHY layer. For example, the DU can implement the high-layer functions in the PHY layer, and the RU can implement the low-layer functions in the PHY layer. When used for transmission, the functions of the PHY layer can include at least one of the following: adding cyclic redundancy check (CRC) bits, channel coding, rate matching, scrambling, modulation, layer mapping, precoding, resource mapping, physical antenna mapping, or radio frequency transmission functions. When used for reception, the functions of the PHY layer can include at least one of the following: CRC check, channel decoding, descrambling, demodulation, de-layer mapping, channel detection, resource demapping, physical antenna demapping, or radio frequency reception functions. The high-layer functions in the PHY layer can include a part of the functions of the PHY layer, and this part of the functions is closer to the MAC layer; the low-layer functions in the PHY layer can include another part of the functions of the PHY layer. For example, this part of the functions is closer to the radio frequency functions. For example, the high-layer functions in the PHY layer can include adding CRC bits, channel coding, rate matching, scrambling, modulation, and layer mapping, and the low-layer functions in the PHY layer can include precoding, resource mapping, physical antenna mapping, and radio frequency transmission functions; or, the high-layer functions in the PHY layer can include adding CRC bits, channel coding, rate matching, scrambling, modulation, layer mapping, and precoding, and the low-layer functions in the PHY layer can include resource mapping, physical antenna mapping, and radio frequency transmission functions. For example, the high-layer functions in the PHY layer can include CRC check, channel decoding, descrambling, decoding, demodulation, and de-layer mapping, and the low-layer functions in the PHY layer can include channel detection, resource demapping, physical antenna demapping, and radio frequency reception functions; or, the high-layer functions in the PHY layer can include CRC check, channel decoding, descrambling, decoding, demodulation, de-layer mapping, and channel detection, and the low-layer functions in the PHY layer can include resource demapping, physical antenna demapping, and radio frequency reception functions.

[0088] Optionally, the functions of the CU can be further divided to separate the control plane and the user plane and implement them through different entities. The separated entities are the control plane CU entity (i.e., the CU-CP entity) and the user plane CU entity (i.e., the CU-UP entity) respectively. The CU-CP entity and the CU-UP entity can be respectively connected to the DU. In the embodiments of the present application, an entity can be understood as a module or a unit, and its existence form can be a hardware structure, a software module, or a combination of a hardware structure and a software module, which is not limited.

[0089] Optionally, any one of the above CU, CU-CP, CU-UP, DU, and RU can be a software module, a hardware structure, or a combination of a software module and a hardware structure, without limitation. Among them, the existence forms of different entities can be the same or different. For example, CU, CU-CP, CU-UP, and DU are software modules, and RU is a hardware structure. For the sake of concise description, all possible combination forms are not listed one by one here. These modules and the methods they execute are also within the protection scope of the embodiments of the present application. For example, when the method of the embodiments of the present application is executed by an access network device, it can be specifically executed by at least one of CU, CU-CP, CU-UP, DU, or RU.

[0090] To facilitate the understanding of the embodiments of the present application, the terms involved in the present application are briefly described first. Optionally, the explanations of some terms can also refer to the explanations in the 3rd generation partnership project (3GPP) standard protocol.

[0091] 1. XR service The XR service includes, but is not limited to, one or more of the following services: AR service, VR service, MR service, and cloud gaming. In the embodiments of the present application, the terminal device can be a device for implementing the XR service.

[0092] The XR service has relatively high requirements for transmission latency. If the data of the XR service is not transmitted successfully within the latency budget, the data of the XR service will time out and thus become ineffective. Exemplarily, for the uplink AR service, its typical packet delay budget (PDB) is 30 ms, that is, the upper limit of the transmission latency of the data packet is 30 ms. If the data packet is not transmitted successfully within the time required by this PDB, it is considered that this data packet has timed out and become ineffective.

[0093] 2. Remaining time of the logical channel and remaining time threshold Taking the XR service as an example, in order to avoid affecting the service experience due to timeout, the data of the XR service needs to complete data scheduling and transmission within the latency budget. For the uplink XR service, in order to enable the network device to understand the consumption of the latency budget of the data in the UE cache, the concept of remaining time and the reporting mechanism have been introduced in 3GPP currently.

[0094] Also, to meet the services that need to temporarily boost the priority when the latency is approaching, 3GPP further proposes a remaining time threshold for each logical channel (LCH). The remaining time threshold is used to trigger the additional priority of the logical channel. The additional priority refers to the additional priority introduced in addition to the initial priority (or static priority) of the logical channel. Moreover, only one additional priority is configured for each logical channel. That is, when the remaining time is less than or equal to the remaining time threshold, the additional priority of the logical channel is triggered. Among them, each logical channel is configured with an additional priority for enhancing the logical channel prioritization (LCP). By providing a dynamic dual-priority policy for the same LCH, the priority can be temporarily boosted during critical periods to optimize the transmission reliability of XR services. For example, the critical period refers to the time period when the data latency of the XR service is approaching the threshold.

[0095] A unified explanation is given here. The terms involved in the embodiments of this application (including the terms introduced here and the terms involved in the implementation manners hereinafter) do not limit the protection scope of the embodiments of this application. For example, the above terms "remaining time" or "remaining time threshold" do not limit the protection scope of the embodiments of this application. In fact, the terms involved in the embodiments of this application can be equivalently replaced by other terms or names with the same function or role.

[0096] 3. Channel Quality Channel quality refers to the quality of the physical channel. Channel quality can be characterized by parameters used to measure and / or describe channel quality or performance. For example, channel quality can be characterized by one or more of the following quantization metrics: reference signal received power (RSRP), block error rate (BLER), reference signal received quality (RSRQ), received signal strength indicator (RSSI), signal to interference and noise ratio (SINR), signal to noise ratio (SNR), channel quality indicator (CQI), correlation and other metric indicators. It should be understood that the metric indicators for channel quality in the embodiments of this application are not limited.

[0097] In the embodiments of the present application, the channel quality of the uplink channel or the downlink channel can be characterized by the above quantization metrics, and the embodiments of the present application do not make specific limitations thereto.

[0098] It should be understood that the quantization metrics shown above are only exemplary descriptions, and the embodiments of the present application are not limited thereto. In fact, those skilled in the art can use other reasonable methods or metrics to characterize the channel quality.

[0099] Currently, the remaining time threshold is a key parameter for triggering the extra priority of the logical channel, but there is no clear conclusion in the standard protocol on how to determine the remaining time threshold of the logical channel.

[0100] In view of this, the embodiments of the present application provide a communication method that uses the channel quality as a decision factor for the remaining time threshold, can dynamically adjust the remaining time threshold, enables the UE to dynamically adjust the logical channel priority based on the remaining time threshold, and thus improves the network's support ability for low-latency services.

[0101] The solution provided by the present application will be described in detail below in conjunction with the corresponding flowcharts. It can be understood that in the schematic flowcharts provided by the present application, different devices (such as a UE or a network device) are mainly used as the execution subjects of the interaction schematic to illustrate the method, but the present application does not limit the execution subjects of the interaction schematic. For example, the devices (such as a UE or a network device) in the schematic flowcharts can also be a chip, a chip system, or a processor that supports the device to implement the method, and can also be a logic module or software that can implement all or part of the functions of the device.

[0102] For a unified description here, in the interaction process of the embodiments of the present application, the message or signaling interaction involved can use the messages or signaling in the standard, or can also be newly introduced messages or signaling, and the embodiments of the present application do not make specific limitations thereto.

[0103] Figure 3A is an example interaction diagram of a communication method in the embodiments of the present application. It can be understood that Figure 3A the network device in Figure 1 or Figure 2 the access network device shown, or can also refer to the device in the access network device (such as a processor, a chip, or a chip system, etc.); Figure 3A the UE in Figure 1 can be any terminal device (such as an XR device) in Figure 3A or can also refer to the device in the terminal device (such as a processor, a chip, or a chip system, etc.). Among them, Figure 3A the UE in Step 301, the UE obtains a first remaining time threshold, and the first remaining time threshold is determined according to the channel quality of the uplink channel.

[0104] In the embodiments of the present application, the first remaining time threshold is determined by the UE or the network device according to the channel quality of the uplink channel. In other words, the value of the first remaining time threshold specifically depends on the quality of the uplink channel. The first remaining time threshold can be adaptively adjusted, or dynamically adjusted, according to the actual quality of the uplink channel.

[0105] In the case of poor channel quality, the system bit error rate increases, and at the same time the channel capacity decreases, and a lower-order modulation and coding scheme (MCS) or multiple retransmissions are required, resulting in an extended transmission time; if a fixed remaining time threshold is used, it may cause data to not be transmitted in time. Therefore, it is necessary to dynamically adjust the remaining time threshold in the case of poor channel quality. Similarly, in the case of good channel quality, the MCS can be upgraded to a higher order, shortening the transmission time; if a fixed remaining time threshold is used, it may cause the additional priority of the logical channel to be triggered prematurely, causing resources to be preempted by high-priority services, resulting in a decrease in the throughput of low-priority services due to resource preemption, which is not conducive to the fair use of resources. Therefore, it is necessary to dynamically adjust the remaining time threshold in the case of good channel quality. By using the channel quality of the uplink channel as the key parameter for determining the remaining time threshold, the embodiments of the present application can flexibly trigger the priority of each logical channel, achieve refined resource allocation, and meet the low-latency requirements of services. The following describes the determination method of the remaining time threshold.

[0106] Optionally, the value of the first remaining time threshold is negatively correlated with the channel quality, that is, the better the channel quality of the uplink channel, the smaller the value of the first remaining time threshold; the worse the channel quality of the uplink channel, the larger the value of the first remaining time threshold. The channel quality can be characterized by the aforementioned quantization index, that is, the quality of the channel can be characterized by the channel quality value.

[0107] Exemplarily, the value of the first remaining time threshold is negatively correlated with the channel quality, including: when the channel quality value of the uplink channel is within the first channel quality interval, the first remaining time threshold is the first threshold; when the channel quality value of the uplink channel is within the second channel quality interval, the first remaining time threshold is the second threshold; when the channel quality value of the uplink channel is within the third channel quality interval, the first remaining time threshold is the third threshold; wherein, the first channel quality interval, the second channel quality interval, and the third channel quality interval represent gradually better channel quality in sequence; the values of the first threshold, the second threshold, and the third threshold decrease in sequence. Among them, each channel quality interval is determined by a channel quality threshold value (including a channel quality upper limit value and / or a lower limit value).

[0108] Optionally, the above-mentioned first channel quality interval, second channel quality interval, and third channel quality interval are different quality intervals divided by threshold value 1 and threshold value 2. For example, the first channel quality interval is expressed as ; the second channel quality interval is expressed as ; the third channel quality interval is expressed as ; that is, the three channel quality intervals are divided by and obtained by division.

[0109] It should be understood that the embodiments of the present application do not make a specific limitation on the number of channel quality intervals. The above is only described by taking 3 channel quality intervals corresponding to 3 remaining time thresholds as an example. For example, in practical applications, there may be more or fewer channel quality intervals; correspondingly, the remaining time thresholds corresponding to the channel quality intervals may also be more or fewer remaining time thresholds.

[0110] It should also be understood that the embodiments of the present application do not make a limitation on the values of the upper boundary and / or lower boundary corresponding to each channel quality interval. For example, the values of the upper boundary and / or lower boundary corresponding to the channel quality interval can be reasonable values determined by the network device based on historical data, or values determined based on the actual situation of the channel quality. The embodiments of the present application do not make a limitation on the specific manner in which the UE obtains the first remaining time threshold.

[0111] Optionally, the first remaining time threshold is directly sent by the network device to the UE; or, the first remaining time threshold is determined by the UE according to the channel quality of the uplink channel and the corresponding relationship between the first remaining time threshold and the first channel quality interval. Among them, the corresponding relationship between the first remaining time threshold and the first channel quality interval can be predefined by the protocol or sent by the network device to the UE.

[0112] The embodiments of the present application do not specifically limit the representation form or corresponding manner of the correspondence between the first remaining time threshold and the first channel quality interval. For example, the correspondence between the first remaining time threshold and the first channel quality interval can be a one-to-one relationship or a one-to-many relationship. For another example, the correspondence between the first remaining time threshold and the first channel quality interval is presented in the form of a first mapping table.

[0113] The first mapping table refers to the mapping relationship between the channel quality interval and the remaining time threshold. It can be understood that the first mapping table includes one or more corresponding relationships, and each corresponding relationship is a mapping relationship or an association relationship between the channel quality interval and the remaining time threshold. For example, the corresponding relationship between the aforementioned channel quality intervals (including the first channel quality interval, the second channel quality interval, and the third channel quality interval) and the first remaining time threshold can constitute the first mapping table.

[0114] Regarding the specific acquisition method of the first remaining time threshold, it will be described in detail later in combination with Figure 4 and Figure 5 the interaction process shown in

[0115] Step 302, the UE determines the priority of the first logical channel according to the first remaining time threshold. The first logical channel can generally refer to any logical channel in the UE. That is, the first logical channel is only introduced for the convenience of description, and the method of the embodiments of the present application is not limited to a specific logical channel. Optionally, the first logical channel at least includes the data to be transmitted of the first service. The first service is generally used to refer to a service with high requirements for delay, or a low-latency service, or a service with low-latency requirements. For example, the first service is an XR service. For another example, the data to be transmitted is the critical delay data of the XR service.

[0116] The embodiments of the present application do not specifically limit the service type of the data to be transmitted in the first logical channel. Optionally, in addition to including the data to be transmitted of the first service, the first logical channel may further include the data to be transmitted of other services.

[0117] After obtaining the first remaining time threshold, the UE monitors the remaining time in the logical channel, so as to adjust the priority of the first logical channel, or improve the priority of the first logical channel, based on the remaining time and the first remaining time threshold, to meet the requirements of low-latency services.

[0118] Optionally, step 302 includes: when the remaining time of the data to be transmitted in the first logical channel is less than or equal to the first remaining time threshold, the priority of the first logical channel is determined from the first priority to the second priority, and the second priority is higher than the first priority, and the first priority is the initial priority of the first logical channel.

[0119] Among them, the second priority can be understood as the additional priority of the first logical channel. For the description of the additional priority, reference can be made to the foregoing text. For the sake of brevity, it will not be elaborated here. The first remaining time threshold can be understood as the trigger threshold for triggering the additional priority of the logical channel.

[0120] That is to say, the UE monitors in real time the remaining time of the data to be transmitted of the first service in the first logical channel; when the remaining time reaches (for example, the remaining time is equal to the first remaining time threshold) the first remaining time threshold, the additional priority of the first logical channel is triggered, or in other words, the priority of the first logical channel is increased. In this way, transmission resources will be preferentially allocated to the first logical channel, which can ensure the smooth transmission of the data to be transmitted on the first logical channel.

[0121] It should be noted that the remaining time threshold is independently configured for each logical channel. The embodiments of the present application do not specifically limit whether the remaining time thresholds of each logical channel are the same, that is, the remaining time thresholds corresponding to each logical channel may be the same or different.

[0122] Exemplarily, the UE's determination of the priority of a certain logical channel may include the following first stage and second stage. The method of the embodiments of the present application is applied to the second stage. In the first stage (or called the initial stage), the UE allocates uplink resources for each logical channel according to the 3GPP protocol according to the static priority and prioritised bit rate (PBR) of the logical channel. The reason for the UE to allocate uplink transmission resources in the first stage is: to avoid affecting the throughput of other services and ensure the fairness of resource allocation; that is to say, since the XR service (or XR traffic) has a burst period and a stable period, and different XR services have different latency requirements, even for the XR service, the UE cannot allocate a very high priority to the logical channel where the XR service is located throughout the process, and the continuous resource preemption by the XR service is not conducive to the throughput of other services and the fairness of resource allocation. In the second stage, the UE dynamically increases the priority of the logical channel by monitoring the magnitude relationship between the remaining time of the XR service in the logical channel and the remaining time threshold. That is, when the remaining time is less than or equal to the remaining time threshold, the logical channel is triggered to temporarily increase the priority to optimize the transmission reliability of the XR service.

[0123] It should also be noted that when the UE allocates transmission resources according to the priority of the logical channel, it can preferentially allocate resources to the logical channel containing delay-critical data. Delay-critical data can be understood as data with high requirements for time delay, such as XR data. For the logical channel containing delay-critical data, the UE will trigger an additional priority when the remaining time of the delay-critical data in the logical channel reaches the remaining time threshold, and preferentially allocate transmission resources to the delay-critical data.

[0124] Exemplarily, as Figure 3B shown, LCH1 not only includes delay-critical data, but also includes non-delay-critical data, such as non-delay-critical data A and non-delay-critical data B; the data included in LCH2 are all non-delay-critical data, such as non-delay-critical data A and non-delay-critical data B. The UE preferentially allocates transmission resources to LCH1 containing delay-critical data. Specifically, when the remaining time of the delay-critical data in LCH1 reaches the remaining time threshold, an additional priority is triggered, that is, the initial priority of LCH1 is raised to a high priority. Of course, in the case of triggering the additional priority of the logical channel of LCH1, the additional priority is applied to all data of LCH1. For LCH2, the original normal priority, that is, the initial priority of LCH2, is still maintained, and LCH2 will not be upgraded.

[0125] Therefore, through the above delay-aware LCP setting, the UE side can dynamically select the priority of the logical channel, so as to achieve refined resource allocation, ensure that the delay-critical data of the first service can be timely allocated transmission resources, meet the transmission of low-latency services, and at the same time avoid non-delay-critical data from always occupying high-priority resources.

[0126] Step 303, the UE uses the transmission resources to transmit the data to be transmitted on the first logical channel, and the transmission resources are allocated according to the priority of the first logical channel.

[0127] Through step 302, the UE adjusts the priority of the first logical channel, and then the UE allocates transmission resources based on the priority of the first logical channel to realize the transmission of the data to be transmitted on the first logical channel.

[0128] Exemplarily, in the case of raising the priority of the first logical channel from the first priority to the second priority, the UE allocates transmission resources based on the second priority to ensure that low-latency services are timely allocated transmission resources, so as to meet the transmission of low-latency services.

[0129] In an embodiment of the present application, the UE obtains a first remaining time threshold, which is dynamically determined according to the channel quality of the uplink channel; determines the priority of the first logical channel according to the first remaining time threshold; and finally uses the transmission resources to transmit the data to be transmitted on the first logical channel. Compared with using a fixed remaining time threshold, in the embodiment of the present application, the first remaining time threshold is dynamically adjusted according to the channel quality of the uplink channel, and the optimal scheduling of resources is achieved by sensing the channel quality, which helps to improve the transmission reliability of low-latency services and also helps to improve the resource utilization rate.

[0130] As described above, the first remaining time threshold may be directly sent by the network device to the UE or determined by the UE itself. The following describes different implementation manners in combination with Figure 4 and Figure 5 It should be understood that Figure 4 or Figure 5 The devices involved in the interaction process in Figure 3A can refer to the description in

[0131] For the sake of brevity, the following will not elaborate further.

[0131] Referring to Figure 4 , Figure 4 shows an interaction example diagram of the communication method in an embodiment of the present application. As Figure 4 shown, it at least includes the following steps: Step 410, the network device measures the channel quality of the uplink channel.

[0132] It can be understood that the network device can measure or evaluate the channel quality of the uplink channel by measuring the reference signal sent by the UE. In the embodiment of the present application, no specific limitation is imposed on the reference signal sent by the UE.

[0133] Optionally, the method further includes: Step 400, the UE sends a sounding reference signal (SRS) to the network device. Correspondingly, the network device receives the SRS from the UE and measures the channel quality of the uplink channel through the SRS. It can be understood that the SRS is a reference signal for the network device to evaluate the uplink channel quality.

[0134] It should be noted that in the embodiment of the present application, no specific limitation is imposed on the triggering condition for the network device to measure the channel quality of the uplink channel. For example, in order to collect the channel quality information of the uplink channel, the network device can actively measure the channel quality of the uplink channel periodically. Another example is that the network device can measure the channel quality of the uplink channel based on the request of the UE. Of course, no matter which way triggers the network device to measure the channel quality of the uplink channel, it can provide a basis for determining the first remaining time threshold subsequently.

[0135] Step 420: The network device determines a first remaining time threshold according to the channel quality of the uplink channel.

[0136] After evaluating the channel quality status of the uplink channel, the network device can determine the first remaining time threshold based on the channel quality of the uplink channel. Of course, the principle for the network device to determine the first remaining time threshold can also refer to the description above, that is, the value of the first remaining time threshold specifically depends on the quality of the uplink channel.

[0137] Optionally, the value of the first remaining time threshold is negatively correlated with the channel quality. The description of the negative correlation between the value of the first remaining time threshold and the channel quality can refer to the description of step 301 above. For the sake of brevity, it will not be elaborated here. In addition, the quantization index of the channel quality can refer to the description above and will not be elaborated here.

[0138] Step 430: The network device sends a first signaling to the UE. Correspondingly, the UE receives the first signaling. The first signaling includes the first remaining time threshold.

[0139] That is to say, after determining the first remaining time threshold, the network device can send the first remaining time threshold to the UE through the first signaling, so that the UE can determine the remaining time threshold of the first logical channel.

[0140] The embodiments of this application do not specifically limit the type of the first signaling. Optionally, the first signaling is any one of the following signaling: media access control control element (MACCE) signaling, radio resource control (RRC) signaling, and downlink control information (DCI).

[0141] Step 440: The UE determines the priority of the first logical channel according to the first remaining time threshold.

[0142] Step 450: The UE uses the transmission resources to transmit the data to be transmitted on the first logical channel, and the transmission resources are allocated according to the priority of the first logical channel.

[0143] For the descriptions of step 440 and step 450, reference can be made to the descriptions of step 302 and step 303 above respectively. For the sake of brevity, it will not be elaborated here.

[0144] Based on Figure 4In the interaction process shown, the network device directly sends the first remaining time threshold to the UE. This method saves the process for the UE to determine the first remaining time threshold. For example, it omits the process of querying the remaining time threshold in the mapping table, and the implementation method is relatively simple. Moreover, since the first remaining time threshold is determined according to the channel quality of the uplink channel, and the network device measures the channel quality result of the uplink channel more accurately, that is, the channel quality result measured by the network device can accurately reflect the actual situation of the uplink channel, so the determined first remaining time threshold is also more appropriate.

[0145] Reference Figure 5 , Figure 5 shows another interaction example diagram of the communication method according to an embodiment of the present application. Compared with Figure 4 the interaction process shown, in Figure 5 the interaction process shown, what the network device sends to the UE is the first mapping table, rather than directly sending the first remaining time threshold. As Figure 5 shown, it at least includes the following steps: Step 510, the network device measures the channel quality of the uplink channel.

[0146] Optionally, the method further includes: Step 500, the UE sends a sounding reference signal SRS to the network device. Correspondingly, the network device receives the SRS from the UE.

[0147] The descriptions of Step 510 and Step 500 can refer to the descriptions of Step 410 and Step 400 in the previous text. For the sake of brevity, they are not elaborated here.

[0148] Step 520, the network device determines the first mapping table according to the channel quality of the uplink channel.

[0149] Optionally, the network device determines the first mapping table according to different channel quality values. For example, the different channel quality intervals described above correspond to different remaining time thresholds.

[0150] Exemplarily, the first mapping table is shown in Table 1 below: Table 1

[0151] In Table 1 above, the first column represents different channel quality intervals or rather channel quality ranges, representing the channel quality value of the uplink channel; the second column represents different remaining time thresholds, and . Taking the corresponding relationship shown in the second row of Table 1 as an example, when , the remaining time threshold is T1. In the embodiments of the present application, the value of the remaining time threshold is adaptively adjusted according to the channel quality, which helps to reduce the delay and improve the transmission reliability.

[0152] A unified description is given here. The content included in the first mapping table shown in the embodiments of the present application is only an exemplary description. In fact, the first mapping table may include a greater or smaller number of corresponding relationships (i.e., the corresponding relationship between the channel quality interval and the remaining time threshold).

[0153] It should be noted that the value of the remaining time threshold in the embodiments of the present application is adaptively adjusted according to the channel quality. Exemplarily, the value of the remaining time threshold is determined in the following manner: When the channel quality is poor, by increasing the value of the remaining time threshold, such as T1 in Table 1, the additional priority of the logical channel can be triggered in advance (i.e., the initial priority of the logical channel is adjusted to the additional priority, or the priority of the logical channel is increased), so as to compensate for the problems of channel quality degradation and retransmission time consumption, so that low-latency services (such as XR services) can ensure low latency and packet loss rate even when the channel quality is poor.

[0154] When the channel quality is medium, the value of the remaining time threshold is set to the reference threshold, such as T2 in Table 1, to achieve smooth adjustment of the remaining time threshold.

[0155] When the channel quality is good, by reducing the value of the remaining time threshold, such as T3 in Table 1, unnecessary preemption can be reduced and transmission resources can be released, so as to improve the throughput of non-critical services (or non-critical data), which helps to achieve more refined scheduling, helps to optimize resource utilization, and ensures the dynamic balance of service priorities. Among them, non-critical services refer to services with low requirements for latency, or ordinary services, or non-first services.

[0156] In the case where various services (such as the first service and non-critical services) coexist in the UE, based on the above adaptive adjustment method, the remaining time threshold can be dynamically adjusted according to the channel quality, so as to simultaneously take into account the low latency of the first service and the high throughput requirements of non-critical services.

[0157] It should be understood that the first mapping table shown in Table 1 above is only an exemplary description, and the embodiments of the present application are not limited thereto. For example, the first mapping table shown in Table 2 below is described by taking the channel quality value as SINR.

[0158] Exemplarily, the first mapping table is as shown in Table 2 below: Table 2

[0159] In Table 2, the channel quality of the uplink channel is characterized by SINR, that is, the channel quality value in the channel quality interval is the SINR value. In Table 2 It can be a preset reference threshold (or reference threshold) for different XR service types (such as AR service, VR service, cloud game, or MR service). The embodiments of the present application do not specifically limit the preset reference thresholds for each service type. For example, The value can be a prior value or a reasonable value set based on actual requirements.

[0160] It should be noted that the relationship between the remaining time threshold and the channel quality interval in Table 2 also satisfies the aforementioned principle: that is, the better the channel quality of the uplink channel, the smaller the value of the remaining time threshold; the worse the channel quality of the uplink channel, the larger the value of the remaining time threshold. Based on this principle, the coefficient involved in Table 2 that is multiplied satisfies the following conditions: .

[0161] It should be understood that the above description of the value range of each coefficient is only an example, and the embodiments of the present application are not limited thereto.

[0162] It should also be understood that Table 2 only describes SINR as an example for characterizing the channel quality of the uplink channel, and the embodiments of the present application are not limited thereto. For example, SINR in Table 2 can also be replaced by other quantization metrics, including but not limited to RSRP or RSRQ values.

[0163] Step 530, the network device sends a second signaling to the UE. Correspondingly, the UE receives the second signaling. The second signaling includes a first mapping table. The first mapping table at least includes the correspondence between the first remaining time threshold and the first channel quality interval.

[0164] That is to say, the network device can send the first mapping table to the UE through the second signaling so that the UE can query the corresponding remaining time value based on the first mapping table.

[0165] Similarly, the embodiments of the present application do not specifically limit the type of the second signaling. Optionally, the second signaling is any one of the following signaling: Media Access Control Control Element MAC CE signaling, Radio Resource Control RRC signaling, and Downlink Control Information DCI.

[0166] Since the channel condition will change dynamically, after the network device sends the first mapping table, it can periodically update the first mapping table and send the updated first mapping table to the UE. Optionally, the network device updates the first mapping table based on the first period and sends the updated first mapping table to the UE. Correspondingly, the UE receives the updated first mapping table sent by the network device. Of course, the UE can re-determine the remaining time threshold of the logical channel based on the updated first mapping table and the channel quality of the uplink channel.

[0167] Compared with the first mapping table before the update, some or all of the parameters in the updated first mapping table may change, and no specific limitations are imposed thereon. For example, in the updated first mapping table, the division of the channel quality intervals of each uplink channel changes, and the value of the remaining time threshold corresponding to a certain channel quality interval also changes.

[0168] It should be understood that the embodiments of the present application do not specifically limit the message or signaling used by the network device to send the updated first mapping table. For example, the network device sends the updated first mapping table through MAC CE signaling, RRC signaling, or DCI.

[0169] That is to say, the network device can periodically update the first mapping table to adjust the first mapping table according to the actual conditions of the uplink channel, and send the updated first mapping table to the UE, so that the UE can determine the remaining time threshold based on the latest first mapping table, and thus determine the priority of the logical channel.

[0170] It should be noted that here, the example of the network device determining and sending the first mapping table to the UE is described, but the embodiments of the present application are not limited thereto. Optionally, as a possible implementation manner, the first mapping table is pre-defined by the protocol, or the correspondence between the first remaining time threshold and the first channel quality interval is pre-defined by the protocol.

[0171] A unified description is made here. The specific implementation manner of "pre-defined" may include any one of the following: pre-defined by the protocol, or specified by the manufacturer of the communication device, or defined by the communication operator, or pre-set in the communication device when the communication device leaves the factory, or pre-agreed by other agreed manners.

[0172] When the UE obtains the first mapping table, it can look up the corresponding remaining time threshold in the first mapping table through the channel quality value of the uplink channel, or use the channel quality value of the uplink channel to traverse each channel quality interval in the first mapping table and select the corresponding remaining time threshold. Since the UE cannot directly obtain the channel quality of the uplink channel, the UE can measure the channel quality of the downlink link through the downlink reference signal and determine the channel quality of the uplink channel according to the channel reciprocity, which can reduce the uplink measurement overhead of the UE. The process of the UE determining the uplink channel quality is described below in combination with step 541 and step 542.

[0173] Step 541, the UE measures the channel quality of the downlink channel.

[0174] It can be understood that the UE can measure or evaluate the channel quality of the downlink channel by measuring the downlink reference signal sent by the network device. The embodiments of the present application do not specifically limit the downlink reference signal sent by the network device.

[0175] Optionally, step 541 includes: step 540, where the network device sends a channel state information-reference signal (CSI-RS) to the UE. Correspondingly, the UE receives the CSI-RS. The UE measures the downlink channel quality through the CSI-RS.

[0176] Step 542, the UE determines the uplink channel quality according to the downlink channel quality.

[0177] Exemplarily, in a TDD system, the uplink and downlink channels share the same frequency band. Therefore, based on channel reciprocity, the uplink channel quality can be deduced using the measurement result of the downlink channel quality.

[0178] The above steps 541 and 542 can be understood as the process by which the UE determines the uplink channel quality. Of course, if there are other processes for measuring the uplink channel quality, steps 541 and 542 above can be replaced.

[0179] Step 550, the UE determines a first remaining time threshold according to the correspondence between the first remaining time threshold and the first channel quality interval and the uplink channel quality.

[0180] Optionally, the first mapping table at least includes the correspondence between the first remaining time threshold and the first channel quality interval, and the uplink channel quality is within the first channel quality interval.

[0181] That is to say, after the UE obtains the uplink channel quality value through steps 541 and 542, it looks up the channel quality interval that matches the channel quality value in the first mapping table, and selects the remaining time threshold corresponding to the channel quality interval, for example, the first remaining time threshold.

[0182] Step 560, the UE determines the priority of the first logical channel according to the first remaining time threshold.

[0183] Step 570, the UE uses the transmission resources to transmit the data to be transmitted on the first logical channel, and the transmission resources are allocated according to the priority of the first logical channel.

[0184] For the descriptions of steps 560 and 570, reference can be made to the descriptions of steps 302 and 303 above respectively. For the sake of brevity, they are not elaborated here.

[0185] Based on Figure 5In the interaction process shown, the network device sends the first mapping table to the UE, and then the UE looks up the corresponding remaining time threshold in the first mapping table. In this way, the UE is prevented from relying on the real-time scheduling instructions of the network device and can autonomously adjust the remaining time threshold. Moreover, since the UE determines the uplink channel quality using channel reciprocity, the overhead of uplink measurement is reduced.

[0186] In summary, the communication method introduced in the embodiments of the present application dynamically determines the remaining time threshold of the logical channel based on the channel quality of the uplink channel, which helps to improve the transmission reliability, also helps to improve the resource utilization rate, and can meet the low-latency requirements of services.
