Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to a communication method, device and storage medium. BACKGROUND

[0002] With the rapid development of extended reality (XR) technology, virtual reality (VR), augmented reality (AR) and other applications have put forward higher and higher requirements on network bandwidth and low delay. Especially in the context of the next generation of communication networks such as the 5th generation (5G), the demand for real-time data transmission of XR applications is more stringent. In order to ensure the smoothness and immersion of XR experience, the network must be able to dynamically adjust the data transmission rate and accurately control the bandwidth and delay. Through the control of the data transmission rate, resources can be flexibly allocated, network efficiency can be improved, congestion can be avoided, and user experience can be guaranteed. In order to realize the control of the data transmission rate, the network needs the terminal device to report the current data transmission rate, and then realizes the adjustment and control of the rate. How the terminal device reports the current rate becomes a problem to be solved. SUMMARY

[0003] Embodiments of the present application provide a communication method, device and storage medium, wherein a terminal device reports the current rate of a quality of service (QoS) flow whose rate changes, thereby avoiding repeated reporting and saving signaling overhead.

[0004] In a first aspect, embodiments of the present application provide a communication method, which is applied to a terminal device or a chip in a terminal device, and the method comprises: receiving a query request from a network device, wherein the query request is used to request to query the rate of a quality of service (QoS) flow; in response to the query request, sending a response message, wherein the response message indicates whether the current rate of the QoS flow is the same as the historical rate of the QoS flow, and in the case that the current rate of the QoS flow is different from the historical rate of the QoS flow, the response message includes the current rate of the QoS flow; the historical rate of the QoS flow is the rate of the QoS flow last sent by the terminal device to the network device.

[0005] The method of the first aspect is implemented, when the network device queries the rate of the QoS flow of the terminal device, the terminal device reports the current rate of the QoS flow whose current rate changes relative to the historical rate to the network device, and does not report the current rate of the QoS flow which does not change, thereby avoiding repeated reporting of the rate which does not change, and saving signaling overhead.

[0006] In a possible implementation, the query request is used to request to query rates of N QoS flows, where N is an integer greater than or equal to 1.

[0007] The response message includes a first field, which indicates whether the current rate of each QoS flow in the N QoS flows is the same as the historical rate.

[0008] In this way, the network device can determine the QoS flow corresponding to the reported current rate by indicating, through the first field, whether the rate of each QoS flow changes.

[0009] In a possible implementation, the first field includes a first bitmap, different bits in the first bitmap correspond to different QoS flows, and a bit value of a bit in the first bitmap is a first value to indicate that the second field includes a current rate of a corresponding QoS flow that is different from a historical rate, and the bit value of the bit in the first bitmap is a second value to indicate that the current rate of the corresponding QoS flow is the same as the historical rate.

[0010] In this way, the QoS flows whose rates change can be indicated through the bitmap, and signaling overhead can be saved.

[0011] In a possible implementation, the N QoS flows include M first QoS flows, the current rate of the first QoS flow is different from the historical rate of the first QoS flow, and the response message further includes a second field, which includes a current rate of each first QoS flow in the M first QoS flows, where M is an integer greater than or equal to 1 and less than or equal to N.

[0012] In this way, when the network device queries the rates of the N QoS flows, the terminal device reports the current rate of the QoS flow whose rate changes in the N QoS flows to the network device, so that repeated reporting is avoided, and signaling overhead is saved.

[0013] In a possible implementation, the query request includes a third field, the third field includes a second bitmap, different bits in the second bitmap correspond to different QoS flows, and a bit value of a bit in the second bitmap is a first value to indicate that the current rate of a corresponding QoS flow is queried; and bit values of N bits in the second bitmap are the first value, where the N bits are bits corresponding to the N QoS flows.

[0014] In this way, the second bitmap can be used to flexibly indicate the QoS flow that needs to be queried by the network device, and signaling overhead can be saved.

[0015] In a possible implementation, the first bitmap and the second bitmap include the same number of bits, and the first bitmap and the second bitmap include a number of bits greater than or equal to the N;

[0016] The first bitmap and the second bitmap have the same correspondence between bits and QoS flows.

[0017] Implementing this mode, the correspondence between bits in the first bitmap and the second bitmap and QoS flows is the same, and the correspondence between bits and QoS flows is not changed, thereby facilitating the network device to quickly determine the QoS flow corresponding to the current rate in the response message.

[0018] In a possible implementation, the method further includes:

[0019] Determining, from the N QoS flows, a second QoS flow with a current rate same as a historical rate;

[0020] Updating a bit value of a bit corresponding to the second QoS flow in the second bitmap from a first value to a second value to obtain the first bitmap.

[0021] Implementing this mode, when the first bitmap is generated, the bit value of the bit with the first value in the second bitmap can be changed, that is, the bit value of the bit corresponding to the QoS flow with the unchanged rate is updated to the second value, and other bit values remain unchanged, thereby improving the generation efficiency of the first bitmap.

[0022] In a possible implementation, the method further includes:

[0023] Based on expiration of timers corresponding to the M first QoS flows respectively, the response message is sent in response to the query request;

[0024] The M first QoS flows include a critical QoS flow and / or a non-critical QoS flow, and a delay requirement of the critical QoS flow is higher than a delay requirement of the non-critical QoS flow.

[0025] The timer corresponding to the critical QoS flow has a timing duration less than a timing duration of the timer corresponding to the non-critical QoS flow.

[0026] Implementing this mode, different timing durations of timers are set for the critical QoS flow and the non-critical QoS flow respectively, thereby realizing high-frequency and real-time reporting of the critical QoS flow and low-frequency and throttling reporting of the ordinary flow.

[0027] In a possible implementation, the method further includes:

[0028] receive a timing duration of a timer corresponding to the key QoS flow and a timing duration of a timer corresponding to the non-key QoS flow.

[0029] In this way, the timing duration of the timer corresponding to the key QoS flow and the timing duration of the timer corresponding to the non-key QoS flow are distinguished, so that the key QoS flow is reported in high frequency and real time, and the ordinary flow is reported in low frequency and throttling.

[0030] In a possible implementation, after the response message is sent, the method further includes:

[0031] restart the timers corresponding to the M first QoS flows, respectively.

[0032] In this way, the rate reporting of the QoS flow is controlled by restarting the timer and timing expiration, so that the rate reporting frequency of each QoS flow is reasonably controlled.

[0033] In a possible implementation, the timing duration of the timer corresponding to the key QoS flow and the timing duration of the timer corresponding to the non-key QoS flow are determined based on a physical resource block (PRB) utilization rate and a channel quality indicator (CQI).

[0034] In this way, the timing duration of the timer corresponding to the key QoS flow and the timing duration of the timer corresponding to the non-key QoS flow can be accurately set.

[0035] In a possible implementation, the method further includes:

[0036] receiving indication information from the network device, the indication information being used to indicate that differential reporting is allowed, the differential reporting being reporting the QoS flow with different current rate and historical rate;

[0037] In response to the query request, sending a response message, including:

[0038] In response to the query request, sending the response message according to the indication information.

[0039] In this way, when the network device indicates that the differential reporting is allowed, the terminal device differentially reports. If the network device indicates that the differential reporting is not allowed, such as the network device does not support or the terminal device does not support the differential reporting, the terminal device reports the current rate of the N QoS flows, so as to be compatible with the existing rate reporting mode and meet various scene requirements.

[0040] In a second aspect, an embodiment of the present application provides a communication method, the method being applied to a network device or a chip in the network device, and the method includes: sending a query request to a terminal device, the query request being used to query a rate of a quality of service (QoS) flow.

[0041] receiving a response message;

[0042] The response message indicates whether the current rate of the QoS flow is the same as the historical rate of the QoS flow, and in the case where the current rate of the QoS flow is different from the historical rate of the QoS flow, the response message includes the current rate of the QoS flow. The historical rate of the QoS flow is the rate of the QoS flow that the terminal device last sent to the network device.

[0043] In a possible implementation, the query request is used to request to query the rates of N QoS flows, where N is an integer greater than or equal to 1.

[0044] The response message includes a first field, and the first field indicates whether the current rate of each QoS flow in the N QoS flows is the same as the historical rate of the QoS flow.

[0045] In a possible implementation, the first field includes a first bit map, different bits in the first bit map correspond to different QoS flows, and a bit value of a bit in the first bit map is a first value to indicate that the current rate of the corresponding QoS flow is different from the historical rate of the QoS flow, and the bit value of the bit in the first bit map is a second value to indicate that the current rate of the corresponding QoS flow is the same as the historical rate of the QoS flow.

[0046] In a possible implementation, the N QoS flows include M first QoS flows, and the current rate of the first QoS flow is different from the historical rate of the first QoS flow.

[0047] The response message further includes a second field, and the second field includes the current rate of each first QoS flow in the M first QoS flows, where M is an integer greater than or equal to 1 and less than or equal to N.

[0048] In a possible implementation, the query request includes a third field, and the third field includes a second bit map, different bits in the second bit map correspond to different QoS flows, and a bit value of a bit in the second bit map is a first value to indicate that the current rate of the corresponding QoS flow is queried; and N bits in the second bit map have the first value, where the N bits are bits corresponding to the N QoS flows.

[0049] In a possible implementation, the number of bits included in the first bit map and the second bit map is the same, and the number of bits included in the first bit map and the second bit map is greater than or equal to N.

[0050] The first bitmap and the second bitmap have the same correspondence between bits and QoS flows.

[0051] In a possible implementation, the M first QoS flows include critical QoS flows and / or non-critical QoS flows, the latency requirement of the critical QoS flows is higher than that of the non-critical QoS flows.

[0052] The timing duration of the timer corresponding to the critical QoS flows is less than the timing duration of the timer corresponding to the non-critical QoS flows.

[0053] The method further includes:

[0054] The timing duration of the timer corresponding to the critical QoS flows and the timing duration of the timer corresponding to the non-critical QoS flows are transmitted.

[0055] In a possible implementation, the method further includes:

[0056] The timing duration of the timer corresponding to the critical QoS flows and the timing duration of the timer corresponding to the non-critical QoS flows are determined based on physical resource block (PRB) utilization and channel quality indication (CQI) of the network.

For example, the chip system can include a chip and can also include other discrete devices.

[0086] The communication method involved in the embodiments of the present application is described below.

[0087] Please refer to Figure 2 A flowchart of a communication method provided in the embodiments of the present application is shown in FIG. 1, which includes the following steps: Figure 2

[0088] 201, the network device sends a query request. Correspondingly, the terminal device receives the query request.

[0089] ​A query request is used to request the rate of a QoS flow. For example, a network device might periodically poll the terminal device, sending query requests to determine if the rate stored by the network device is up-to-date. Another example is when a network device predicts network congestion and sends query requests to the terminal device. For instance, when a network device detects increased cell load, it can send a query request to the terminal device to obtain its current rate and predict network congestion. Yet another example is when a network device sends a query request to ensure critical services are served, obtaining the current rate of the terminal device and determining if it matches the bandwidth requirements of the critical service, such as the QoS flow of an XR application. Finally, a query request can be sent when a network device detects a network anomaly, obtaining the current rate of the terminal device. For example, if the feedback information sent by the terminal device in the last transaction is lost or incomplete, the terminal device can send a query request.

[0090] In some embodiments, the query request can be used to request the rates of N QoS flows, where N is an integer greater than or equal to 1. In this embodiment, a second bitmap can be used to indicate the N QoS flows to be queried. For example, the query request includes a third field, which includes the second bitmap. Different bits in the second bitmap can correspond to different QoS flows. If the bit value of a bit in the second bitmap is a first value, it indicates that the current rate of the QoS flow corresponding to that bit needs to be queried. Since the network device needs to query the rates of N QoS flows, the bit values ​​of the N bits in the second bitmap are the first values, and these N bits are the bits corresponding to the N QoS flows. The first value can be, for example, 1. The number of bits included in the second bitmap can be greater than or equal to N. If the number of bits included in the second bitmap is equal to N, then the bit values ​​of all bits in the second bitmap are the first values. If the second bitmap includes more than N bits, for example, Q bits (where Q is an integer greater than N), each of the Q bits corresponds to a QoS flow, and these Q QoS flows can be all QoS flows managed by the terminal device. The first value is N bits out of the Q bits. The second value is QN bits excluding the N bits. The second value can be, for example, 0.

[0091] The following is combined with Figure 3 For example, Figure 3 The diagram shown is a schematic of a query request provided in an embodiment of this application. The query request includes a third field, which carries a second bitmap. Figure 3 Taking the second bitmap, which consists of 16 bits (Q=16), as an example, each bit corresponds to a QoS stream. Figure 3QoS flow is identified by QFi. For example, if the third field carries a bitmap as shown in FIG. 8, it indicates that 6 QoS flows, i.e., N = 6, need to be queried, and the identifiers of the 6 QoS flows are QF0, QF1, QF8, QF9, QF10, and QF11, respectively. Figure 4

[0092] 202, the terminal device sends a response message in response to the query request. Correspondingly, the network device receives the response message.

[0093] The response message indicates whether the current rate of the QoS flow is the same as the historical rate of the QoS flow, and in the case where the current rate of the QoS flow is different from the historical rate of the QoS flow, the response message includes the current rate of the QoS flow; the historical rate of the QoS flow is the rate of the QoS flow that the terminal device last sent to the network device.

[0094] The historical rate of the QoS flow can be the rate of the QoS flow that the terminal device last sent to the network device. The last time can be the last time the terminal device has sent the rate of the QoS flow to the network device. For example, the terminal device reports the rate at times t1, t2, and t3, respectively. The times t1, t2, and t3 can be sorted in chronological order. If the terminal device reports the rate of the QoS flows identified by QF0 and QF1 at time t1, the rate of the QoS flows identified by QF9 and QF10 at time t2, and the rate of the QoS flow identified by QF7 at time t3, it is detected that the rate of the QoS flow identified by QF1 has changed. Specifically, the last rate of the QoS flow identified by QF1 sent to the network device is the rate reported at time t1, i.e., the historical rate of the QoS flow identified by QF1 is the rate of the QoS flow identified by QF1 reported at time t1. The current rate of the QoS flow identified by QF1 is different from the historical rate, and therefore the response message needs to include the current rate of the QoS flow identified by QF1.

[0095] The response message can be carried in a media access control (MAC) control element (CE).

[0096] ​In some embodiments, the query request can be used to request querying the rate of N QoS flows. The response message can include a first field indicating whether the current rate of each QoS flow in the N QoS flows is the same as the historical rate. If M QoS flows in the N QoS flows have different current rates and historical rates, for the purpose of description, the M QoS flows are referred to as M first QoS flows, and the response message further includes a second field including the current rate of each first QoS flow in the M first QoS flows, M being an integer greater than or equal to 1 and less than or equal to N. In some embodiments, if the current rate of all QoS flows in the N QoS flows is the same as the historical rate, the first field in the response message can indicate that the rate of the N QoS flows has not changed, and the response message can not include the second field. In the embodiments of the present application, when the network device requests to query the N QoS flows, the terminal device reports the current rate of the QoS flow with different current rate and historical rate, and does not report the QoS flow with the same current rate and historical rate. This reporting method can be referred to as differential reporting.

[0097] For example, the response message includes a first field and a second field, the first field can include a first bit map, different bits in the first bit map correspond to different QoS flows, and a bit value of a bit in the first bit map being a first value indicates that the current rate of the corresponding QoS flow is different from the historical rate, which can also be understood as the bit value of the bit in the first bit map being the first value indicating that the second field includes the current rate of the corresponding QoS flow. The bit value of the bit in the first bit map being a second value indicates that the current rate of the corresponding QoS flow is the same as the historical rate, which can also be understood as the bit value of the bit in the first bit map being the first value indicating that the second field does not include the current rate of the corresponding QoS flow.

[0098] For example, the current rate of M first QoS flows differs from their historical rates. The response message includes the current rates of M first QoS flows. Therefore, the bit values ​​of the M bits in the first bitmap are first values, and these M bits correspond to the M first QoS flows. The bit values ​​of the other bits in the first bitmap besides these M bits are second values. The first value can be, for example, 1, and the second value can be, for example, 0. In this embodiment, the second field includes the current rate of each of the M first QoS flows. The current rates of the M first QoS flows can be sorted in ascending order of the QF index values, or they can be sorted according to the order of the M bits. For example, the second field can include M bitrate fields, each bitrate field including the current rate of a first QoS flow. Bits in the first bitmap with a first value are used to indicate that the second field includes the bitrate field of the corresponding QoS flow, and correspondingly includes the current rate of that QoS flow. Bits in the first bitmap with a second value are used to indicate that the second field does not include the bitrate field of the corresponding QoS flow, and correspondingly does not include the current rate of that QoS flow.

[0099] In this embodiment of the application, the first bitmap included in the response message and the second bitmap included in the query request contain the same number of bits, and the number of bits included in the first bitmap and the second bitmap is greater than or equal to N. The correspondence between each bit in the first bitmap and the second bitmap and the QoS stream is the same.

[0100] The following is combined with Figure 5 For example, Figure 5 The diagram shown is a schematic of a response message provided in an embodiment of this application. The response message includes a first field and a second field. The first field carries a first bitmap, and the correspondence between each bit in the first bitmap and the QoS stream is... Figure 3 The correspondence between each bit in the second bitmap and the QoS stream is the same.

[0101] When generating a response message, the terminal device can determine the second QoS stream with the same current rate as the historical rate from the N QoS streams to be queried, update the bit value of the bit corresponding to the second QoS stream in the second bit map from the first value to the second value to indicate that the rate of the corresponding second QoS stream has not changed, and keep the other bit values ​​in the second bit map unchanged, thus obtaining the first bit map. Below... Figure 6 For example, if the rates of the QoS flows identified by QF8 and QF9 remain unchanged (i.e., the QoS flows identified by QF8 and QF9 are the second QoS flows), update the bit values ​​of the two corresponding bits of QF8 and QF9 from 1 to 0, while keeping the other bit values ​​unchanged, thus obtaining the first bitmap. See [link to documentation]. Figure 6The diagram shown is a schematic of the first bit map carried by the first field.

[0102] It should be noted that if the current rate and historical rate of the N QoS flows are the same, that is, if the rates of the N QoS flows have not changed, the response message sent by the terminal device can include only the first field, in which the first bitmap carried by the first field has all bits set to 0. The response message may not include the second field, thus saving signaling overhead.

[0103] The following is combined with Figure 7 For an example illustrating the differential reporting method of this application, please refer to... Figure 7 This is an example of differential reporting provided in an embodiment of this application. The terminal device synchronizes the rates of each QoS stream to the network device, such as... Figure 7 Table 1 and Figure 7 As shown in Table 2, the terminal device synchronizes the rates of the six QoS flows with the network device. Figure 7 Table 1 shows the correspondence between QoS streams and rates stored on the terminal device. These rates can be understood as historical rates. Figure 7 Table 2 shows the correspondence between QoS flows and rates stored by network devices.

[0104] When the network device queries the terminal device for the current rates of the six QoS flows, the terminal device determines... Figure 7 The current rate of QoS flow 1 in Table 3 is relative to... Figure 7 Table 1 shows the historical rate changes of QoS flow 1. Figure 7 The current rate of QoS flow 2 in Table 3 is relative to Figure 7 The historical rate of QoS flow 2 in Table 1 has changed. Figure 7 Table 3 in the table can be based on the terminal device. Figure 7 From Table 1, when Figure 7 When the rate of the QoS stream in Table 1 changes, the terminal device updates the rate of that QoS stream. Figure 7 Table 3 shows the updated QoS flow and rate correspondence. When a network device queries the QoS flow rate, the terminal device determines that the rates of QoS flow 1 and QoS flow 2 have changed. The terminal device can perform differential reporting, that is, send the current rates of QoS flow 1 and QoS flow 2 to the network device. The terminal device can indicate to the network device that the current rate of QoS flow 1 is 300 Mbps and the current rate of QoS flow 2 is 80 Mbps, thereby allowing the network device to update the rates of QoS flow 1 and QoS flow 2. Figure 8 The rates of QoS flow 1 and QoS flow 2 in Table 4 are updated.

[0105] In some embodiments, the network device can send indication information to the terminal device, the indication information can be used to indicate whether to allow differential reporting, the differential reporting refers to that the terminal device reports the QoS flow with different current rate and historical rate. In the case that the indication information indicates to allow differential reporting, the terminal device sends a response message according to the indication information in response to the query request, the response message includes M first QoS flows with different current rate and historical rate. In the case that the indication information indicates not to allow differential reporting, the terminal device needs to report the current rate of N QoS flows.

[0106] In the embodiments of the present application, the QoS flow can be divided into key QoS flow and non-key QoS flow, the delay requirement of the key QoS flow is higher than that of the non-key QoS flow. The non-key QoS flow can also be referred to as a common QoS flow. The key QoS flow requires low delay, high real-time or strong interactivity, and needs to be transmitted in real time. For example, the key QoS flow can include key control plane information of the XR / VR video stream, and the key control plane information can include, for example, pose position tracking information. For another example, the key QoS flow can include interactive and control signaling flow, and the interactive and control signaling flow can include, for example, XR control instruction and gesture recognition signaling. The delay requirement of the non-key QoS flow is relatively low. For example, the non-key QoS flow can include large bandwidth video data or image data, and the large bandwidth video data or image data can include, for example, texture download in the XR rendering scene and upload of high-definition content. For another example, the non-key QoS flow can include synchronization of background data, and the synchronization of background data can include, for example, application log, statistical data, non-real-time application state reporting, and the like.

[0107] A corresponding timer can be set for the QoS flow, the timer can be used to control the rate reporting of the QoS flow, and the rate of the QoS flow can be reported only when the corresponding timer of the QoS flow expires, which can avoid frequent reporting of the rate of the same QoS flow. The timer can also be referred to as a prohibit timer. In the embodiments of the present application, the current rate of the QoS flow is reported only when the corresponding timer of the QoS flow expires and the current rate of the QoS flow is different from the historical rate, which can also be referred to as differential reporting. That is, the corresponding timers of the M first QoS flows reported in the present application expire, and the current rates of the M first QoS flows are different from the historical rates. Based on the fact that the corresponding timers of the M first QoS flows expire and the current rates of the M first QoS flows are different from the historical rates, the response message is sent, and the response message includes the current rate of each first QoS flow in the M first QoS flows.

[0108] In the embodiments of the present application, the timing duration of the timer corresponding to the key QoS flow is less than the timing duration of the timer corresponding to the non-key QoS flow. For example, the timing duration of the timer corresponding to the key QoS flow is very short, for example, 5 ms-10 ms, so as to ensure that the terminal device can quickly trigger the reporting when the rate of the key QoS flow changes, thereby ensuring the real-time performance. The timing duration of the timer corresponding to the non-key QoS flow is relatively long, for example, 50 ms-100 ms, so as to avoid that the non-key QoS flow is reported frequently and occupies network resources.

[0109] For example, the network device can configure the terminal device with the timing duration of the timer corresponding to the key QoS flow and the timing duration of the timer corresponding to the non-key QoS flow.

[0110] In the embodiments of the present application, one timer corresponds to each QoS flow in the N QoS flows, and the rate reporting of each QoS flow is controlled in a more fine-grained manner. Specifically, the terminal device receives the query request of the network device, and in response to the query request, the terminal device detects the rate state of each QoS flow in the N QoS flows, so as to determine whether the rate of the QoS flow changes (i.e., whether the current rate of the QoS flow is the same as the historical rate). If the rate of the QoS flow changes, the terminal device can detect whether the timer corresponding to the QoS flow expires. If the timer expires, the terminal device can perform the differential reporting of the QoS flow, i.e., the QoS flow is the first QoS flow that needs to be reported. If the timer does not expire, the terminal device waits for the next time to report the current rate of the QoS flow. It can be understood that if the rates of the N QoS flows do not change, the response message sent by the terminal device can only include the first bitmap, or the terminal device can not report until the next time the network device queries. After the current rate of the QoS flow is reported, the timer corresponding to the QoS flow can be restarted. In the embodiments of the present application, the M first QoS flows are the QoS flows whose current rates are different from the historical rates, and the timers corresponding to the M first QoS flows expire, so the response message includes the current rates of the M first QoS flows. After the rates of the M first QoS flows are reported, the timers corresponding to the M first QoS flows are restarted.

[0111] In the embodiments of the present application, the corresponding timer is set for the QoS flow, which can avoid that the terminal device reports the rate of the QoS flow frequently, and can distinguish the key QoS flow and the non-key QoS flow. Different timing durations are set for the corresponding timers, so as to ensure that the key QoS flow is reported preferentially.

[0112] In some embodiments, after the terminal device establishes a connection with the network device, the network state of the cell can be fluctuating, and the network state of the cell can be determined based on a physical resource block (PRB) utilization rate and a channel quality indicator (CQI). In the embodiments of the present application, based on the network state, the time length of the timer corresponding to the key QoS flow and the non-key QoS flow is set (or determined). Based on the network state, the time length of the timer corresponding to the key QoS flow and the non-key QoS flow can also be understood as being based on the PRB utilization rate and the CQI to set (or determine) the time length of the timer corresponding to the key QoS flow and the non-key QoS flow. As shown in Table 1, the network state corresponding to the PRB utilization rate and the CQI in different ranges:

[0113] Table 1

[0114]

[0115] Among them, the PRB utilization rate < 60% means that the cell resources are relatively free. The CQI is the channel quality score reported by the terminal device, usually in the range of 0-15, the larger the number, the better the signal quality, which can use higher order modulation coding, such as 64 quadrature amplitude modulation (QAM), 256 QAM, and higher transmission rate. CQI ≥ 10 means that the channel is very good, the block error rate (BLER) is low, and the high-speed transmission can be safely carried out.

[0116] When the PRB utilization rate < 60% and the CQI ≥ 10, it means that the resources are abundant and the link condition is good. The terminal device is allowed to report the key QoS flow and the non-key QoS flow more frequently, that is, even if the network device triggers multiple queries at the same time, the terminal device can also prioritize uploading the key QoS flow query according to the uplink shared channel (UL-SCH) resource capacity, and the non-key QoS flow query continues to remain in a pending state, waiting for the next UL resource.

[0117] Please refer to Figure 8 for a specific example of a communication method provided by the embodiments of the present application. As shown in Figure 2 , the communication method includes but is not limited to the following steps:

[0118] 801, the terminal device establishes a radio resource control (RRC) connection with the network device.

[0119] 802, the network device sends configuration information to the terminal device. Correspondingly, the terminal device receives the configuration information.

[0120] The configuration information can be configured through an RRC layer.

[0121] The configuration information can include at least one of the following: a duration of a timer corresponding to a critical QoS flow, a duration of a timer corresponding to a non-critical QoS flow, and indication information indicating whether differential reporting is allowed. Differential reporting refers to the terminal device reporting the current rate of a QoS flow whose current rate is different from the historical rate. For details, see the description of the foregoing embodiments. Figure 2 For example, the duration of the timer corresponding to the critical QoS flow is 10 ms, and the duration of the timer corresponding to the non-critical QoS flow is 80 ms.

[0122] 803, the network device sends a query request to the terminal device. Correspondingly, the terminal device receives the query request.

[0123] For details of the query request, see the related description of the foregoing embodiments. Figure 9

[0124] 804, the network device allocates uplink channel resources to the terminal device.

[0125] The network device can send an uplink grant to the terminal device, and the terminal device obtains the uplink channel resources.

[0126] After the logical channel priority is sorted, the terminal device can determine whether the allocated uplink channel resources can accommodate the MAC CE carrying the response message. If the uplink channel resources are sufficient and can accommodate the current rates of all OoS flows in the N QoS flows whose rates have changed, the terminal device differentially reports the N OoS flows, that is, reports the OoS flows whose rates have changed. If the uplink channel resources are insufficient and cannot accommodate the current rates of all OoS flows in the N QoS flows whose rates have changed, the terminal device can select to differentially report the critical QoS flow first.

[0127] 805, the terminal device differentially reports to the network device.

[0128] For details of the differential reporting method, see the related description of the foregoing embodiments. For example, the terminal device reports the rate of a QoS flow whose current rate is different from the historical rate.

[0129] ​When the network state is good and stable, such as a good channel or a medium channel, the key QoS flow and the non-key QoS flow can be set with a short timer length, the network device triggers a query request once, and the terminal device differentially reports the current rate of the key QoS flow and the non-key QoS flow together. When the network state is poor and unstable, such as a congested channel, the network device can trigger multiple query requests, the timer length set for the key QoS flow is less than the timer length set for the non-key QoS flow, and the terminal device can preferentially differentially report the key QoS flow, and the differential reporting of the non-key QoS flow can wait for the next scheduling and query of the network device. The network state determination method is described in the foregoing embodiments.

[0130] The following is an example of a scenario to which the embodiments of the application can be applied:

[0131] 1. 5G network and industrial Internet of Things application

[0132] The rate reporting mechanism of the embodiments of the application can be widely applied to ultra-reliability and ultra-low latency communication (URLLC) in a 5G network, such as intelligent factories, remote medical care, and the like. In these scenarios, key QoS flows such as control signaling and device monitoring data require low latency and high reliability, while non-key QoS flows such as background logs and status updates allow for delayed processing. By hierarchically managing the timer lengths of the key QoS flow and the non-key QoS flow, high-priority key QoS flows can be ensured to be uploaded in time, while the overhead of low-priority QoS flows is reduced, and resource utilization is optimized.

[0133] 2. Augmented reality, virtual reality, and smart city

[0134] In augmented reality (AR) / virtual reality (VR) applications, such as XR games and interactive experiences, the rate reporting mechanism of the embodiments of the application can ensure that real-time data such as pose, position tracking, and control signaling are preferentially uploaded, avoiding the discomfort caused by delay. While scene rendering, video content, and the like can be uploaded in batches when resources are sufficient, ensuring a smooth user experience. Similarly, the rate reporting mechanism of the embodiments of the application can also be very effective in traffic control in a smart city, ensuring that key QoS flows such as traffic signals and control instructions are not delayed due to resource shortages.

[0135] 3. Smart home and medical health field

[0136] In the field of smart home and medical health, the rate reporting mechanism of the embodiments of the present application can effectively distinguish between key QoS flows and non-key QoS flows. Key QoS flows such as emergency alarm signals, device control instructions, etc. are preferentially transmitted to ensure home safety and real-time response. Non-key QoS flows such as environmental data, health monitoring information, etc. can be uploaded with delay to reduce bandwidth occupation. In remote medical treatment and surgery, the uploading of real-time monitoring data and video streams is particularly important, while non-real-time diagnostic information can be uploaded with delay.

[0137] 4. Satellite communication and deep space exploration

[0138] The rate reporting mechanism of the embodiments of the present application can also have important applications in satellite communication and deep space exploration environments. Through the rate reporting mechanism of the embodiments of the present application, key data such as satellite control signaling and positioning information can be preferentially transmitted to ensure that ground stations can respond in time in emergency situations. While ordinary flows such as satellite images and monitoring data can be uploaded with delay to optimize the use of satellite bandwidth and ensure the immediacy and accuracy of important information.

[0182] Figure 9 The specific description of the apparatus embodiment and the beneficial effects can refer to the description of the foregoing method embodiments, and will not be described here.

[0183] The terminal device and the network device of the embodiments of the present application are introduced above, and it should be understood that any form of product that has the functions of the terminal device or the network device described above falls within the protection scope of the embodiments of the present application. Figure 10 The terminal device or Figure 11 The network device has the functions of the terminal device or the network device described above falls within the protection scope of the embodiments of the present application.

[0184] Please refer to Figure 11 , Figure 11is a structural schematic diagram of another communication apparatus provided by an embodiment of the present application, which is used to implement the functions of the network device in the method embodiments or to implement the functions of the terminal device in the method embodiments. The communication apparatus 1300 can be a network device or an apparatus for a network device. The apparatus for a network device can be a chip system or a chip in the network device. The communication apparatus can also be a terminal device or an apparatus for a terminal device. The apparatus for a terminal device can be a chip system or a chip in the terminal device. The chip system can be composed of a chip or can include a chip and other discrete devices.

[0185] The communication apparatus 1300 includes at least one processor 1320, which is used to implement the data processing functions of the network device or the terminal device in the methods provided by the embodiments of the present application. The communication apparatus 1300 can also include a communication interface 1310, which is used to implement the transceiving operations of the network device or the terminal device in the methods provided by the embodiments of the present application. In the embodiments of the present application, the processor 1320 can be a central processing unit (CPU), and the processor can also be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor. In the embodiments of the present application, the communication interface 1310 can be a transceiver, a circuit, a bus, a module or other types of communication interfaces, which are used to communicate with other devices through transmission media. For example, the communication interface 1310 is used for the communication apparatus 1300 to communicate with other devices. The processor 1320 transceives data by using the communication interface 1310, and is used to implement the methods described in the method embodiments.

[0186] The communication apparatus 1300 can also include at least one memory 1330, which is used to store program instructions and / or data. The memory 1330 is coupled with the processor 1320. The coupling in the embodiments of the present application is indirect coupling or communication connection between apparatuses, units or modules, which can be electrical, mechanical or other forms, and is used for information interaction between the apparatuses, units or modules. The processor 1320 can operate cooperatively with the memory 1330. The processor 1320 can execute the program instructions stored in the memory 1330.

Figure 11 (Not shown) The RF circuit processes the baseband signal and then transmits the RF signal outward as electromagnetic waves through the antenna. When data is sent to the communication device 1300, the RF circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 1320. The processor 1320 converts the baseband signal into data and processes the data.

Figure 11 The connections between other components are shown in bold and are for illustrative purposes only, not as limiting information. The bus can be divided into address bus, data bus, control bus, etc. For ease of illustration, ​ The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0190] When the communication device 1300 is specifically used in network equipment, such as when the communication device 1300 is specifically a chip or chip system, the communication interface 1310 can output or receive baseband signals. When the communication device 1300 is specifically a terminal device, the communication interface 1310 can output or receive radio frequency signals.

[0191] It should be noted that the device can perform the relevant steps of the network device or terminal device in the foregoing method embodiments. For details, please refer to the implementation methods provided in the above steps, which will not be repeated here.
