[0002] Based on current discussions in the 3rd Generation Partnership Project (3GPP), support is proposed for rate control involving the Radio Access Network (RAN), where Extended Reality (XR) applications (e.g., by modifying frame rate / resolution during network congestion) dynamically adjust their data rates and coding parameters to ensure a seamless and high-quality user experience. Furthermore, it is feasible for the RAN to estimate congestion information for each Quality of Service (QoS) flow and / or each Data Radio Bearer (DRB) in the downlink and uplink directions, and it is feasible for the RAN to estimate congestion information for each QoS flow and / or each DRB in the uplink (UL) without the influence of User Equipment (UE).

[0038] As stated above, based on current discussions in 3GPP, support for rate control involving the RAN has been proposed, where XR applications (e.g., by modifying frame rate / resolution during network congestion) dynamically adjust their data rates and coding parameters to ensure a seamless and high-quality user experience. The objectives of the XR work items in 3GPP Rel-19 are listed in the table below.

[0039]

[0040]

[0041] Solutions regarding recommended bitrate procedures have been previously proposed. While current solutions to recommended bitrate procedures (such as via MAC CE) can provide information similar to that expected for XR rate control, there are aspects of XR rate control that are not supported by the currently specified recommended bitrate MAC CE. As an example, currently, a total of 64 QoS flow IDs can be supported, but not all QoS flows will be associated with XR rate control. Therefore, an indication supporting all possible QoS flows is unnecessary. The problem is that the current recommended bitrate procedure cannot support rate control for every QoS flow / DRB. Another example is that different XR applications can support different ranges of bitrate adaptation. Additionally, all bitrates supported in the recommended bitrate procedure (e.g., from 0 kbps to 8,000 kbps) may not be used for XR, as XR is primarily designed for high data rates. Another example is that in the current solution, the UE can continue using the old bitrate even when congestion is resolved, without the UE querying for a new bitrate. The only way to achieve this is to send another rate control signal to the UE at the cost of increased overhead and resources, given the number of QoS flows. Other examples will not be listed.

[0042] At least some of the above problems can be solved according to the example embodiments of this disclosure.

[0043] In the context of this disclosure, QoS flows are used as examples of data flows to describe some specific example embodiments of this disclosure. Note that such example embodiments described are for illustrative purposes only and do not imply any limitation. In fact, the solutions discussed herein can be applied to other data flows, including but not limited to DRB, LCH, LCG, MMS, etc.

[0044] In the context of this disclosure, uplink data rate control is used as an example of data flow to describe some specific example embodiments of this disclosure. Note that such example embodiments described are for illustrative purposes only and do not imply any limitation. In fact, the solutions discussed herein can be applied to both uplink data rate control and downlink data rate control.

[0045] In the context of this disclosure, the terms "data rate control" and "bit rate control" are used interchangeably.

[0046] Example Environment Figure 1An example communication environment 100 in which exemplary embodiments of the present disclosure can be implemented is shown. The communication environment 100 includes a first device 110 and a second device 120. The service area provided by the second device 120 is called a cell. Furthermore, the second device 120 can provide one or more cells; for example, cell 102 is provided by the second device 120, such as... Figure 1 As shown.

[0047] In some example embodiments, the first device 110 may be included in the terminal device / apparatus, and the second device 120 may be included in the network device / apparatus serving the terminal device / apparatus.

[0048] In some example embodiments, the transmission direction from the second device 120 to the first device 110 is referred to as the downlink (DL), and the transmission direction from the first device 110 to the second device 120 is referred to as the uplink (UL). In the DL, the second device 120 is a transmitting (TX) device (or transmitter), and the first device 110 is a receiving (RX) device (or receiver). In the UL, the first device 110 is a TX device (or transmitter), and the second device 120 is an RX device (or receiver).

[0049] In the following description, for illustrative purposes, some exemplary embodiments are depicted in which the first device 110 operates as a terminal device and the second device 120 operates as a network device. However, in some exemplary embodiments, the operations described in connection with the terminal device can be implemented at the network device or other devices, and the operations described in connection with the network device can be implemented at the terminal device or other devices.

[0050] In some example embodiments, if the first device 110 is a terminal device and the second device 120 is a network device, the link from the second device 120 to the first device 110 is referred to as a downlink (DL), and the link from the first device 110 to the second device 120 is referred to as an uplink (UL). In the DL, the second device 120 is a transmitting (TX) device (or transmitter), and the first device 110 is a receiving (RX) device (or receiver). In the UL, the first device 110 is a TX device (or transmitter), and the second device 120 is an RX device (or receiver).

[0051] It should be understood that Figure 1The number of devices and their connections shown are for illustrative purposes only and do not imply any limitation. Communication environment 100 may include any suitable number of devices configured to implement the exemplary embodiments of this disclosure. Although not shown, it should be understood that one or more additional devices may be located in cell 102, and one or more additional cells may be deployed in communication environment 100. It should be noted that although the second device 120 is shown as a network device, the second device 120 may be another device different from a network device. Although shown as a terminal device, the first device 110 may be another device other than a terminal device.

[0052] Communication in communication environment 100 can be implemented according to any suitable communication protocol(s), including but not limited to cellular communication protocols, wireless local area network communication protocols (such as IEEE 802.11, etc.) and / or any other currently known or future-developed protocols. Furthermore, communication can utilize any suitable wireless communication technology, including but not limited to: Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplex (FDD), Time Division Duplex (TDD), Multiple Input Multiple Output (MIMO), Orthogonal Frequency Division Multiple Access (OFDM), Discrete Fourier Transform Extended OFDM (DFT-s-OFDM) and / or any other currently known or future-developed technologies.

[0053] Working principles and example signaling for communication The specified recommended bit rate procedure provides a framework for controlling the bit rate based on, for example, radio link quality. In operation, the recommended bit rate procedure can be used to provide the MAC entity with information about the recommended bit rate for the gNB. The bit rate is the recommended bit rate at the physical layer. An average window with a default value of 2000ms will be applied.

[0054] The gNB can send a recommended bit rate MAC control element (CE) to the UE's MAC entity (as...). Figure 2A The example MACCE structure in the example indicates the recommended bit rate for a UE for a specific logical channel and a specific direction (uplink or downlink).

[0055] Upon receiving a recommended bit rate MAC CE, the MAC entity can indicate the recommended bit rate to the upper layer for the indicated logical channel and direction.

[0056] In addition, the MAC entity can request the gNB to indicate a recommended bit rate for a specific logical channel and direction. If the upper layer requests the MAC entity to query the gNB for a recommended bit rate for a logical channel and direction (i.e., uplink or downlink), the MAC entity will trigger a recommended bit rate query for that logical channel, direction, and desired bit rate if such a query has not yet been triggered.

[0057] If the MAC entity has UL resources allocated for the new transmission, then the MAC entity should: 1> For each recommended bitrate query, the recommended bitrate process is determined to have been triggered and not canceled: 2> If used for logical channels bitRateQueryProhibitTimer If the direction of the recommended bitrate query is configured, it will not run; and 2> If the MAC entity has UL resources allocated for the new transmission, and the allocated UL resources can accommodate the recommended bit rate MAC CE plus its sub-header as the result of Logical Channel Prioritization (LCP): 3> Instructions for the multiplexing and assembly process to generate a recommended bit rate MAC CE for the logical channel and the direction of querying that recommended bit rate; 3> Initiate the logical channel bitRateQueryProhibitTimer And the direction of the recommended bit rate query; 3> Cancel the recommended bitrate query.

[0058] exist Figure 2A In the example, the recommended bit rate MAC CE is identified by a MAC subheader with a Logical Channel Identifier (LCID), which is used for both the bit rate recommendation message from the gNB to the UE and the bit rate recommendation query message from the UE to the gNB. It has a fixed size and consists of two octets defined as follows: -LCID: This field indicates the identifier of the logical channel to which the recommended bit rate or recommended bit rate query applies. The field length is 6. - Uplink / Downlink (UL / DL): This field indicates whether the recommended bit rate or recommended bit rate query is applicable to uplink or downlink. The field length is 1 bit. A UL / DL field set to 0 indicates downlink. A UL / DL field set to 1 indicates uplink; - Bitrate: This field indicates, for example... Figure 2B The index of the table shown. This field is 6 bits long. For bitrate recommendations, this value indicates the recommended bitrate. For bitrate recommendation queries, this value indicates the desired bitrate. -X: Bit rate multiplier. For UEs that support the recommended bit rate multiplier, when configured for the logical channel indicated by the LCID field... bitRateMultiplier When the X field is set to 1, the actual value of the bit rate is multiplied by the index indicated by the bit rate field. bitRateMultiplier The corresponding value.

[0059] -R: Reserve bits, set to 0.

[0060] To support uplink (or downlink) bit rate control, in some example embodiments of this disclosure, the gNB can configure the UE with a bit rate range (to indicate, for example, minimum and maximum bit rates or multiple bit rates). The following bit rate control signaling (e.g., MAC CE) can then be based on the pre-configured bit rate range. Optionally, in this solution, a novel signaling (such as MAC CE) is proposed to carry information including a bit rate index, where the bit rate index can be based on a pre-configured bit rate range, and the size of the bit rate index can be shortened.

[0061] Alternatively or additionally, in some example embodiments of this disclosure, bit rate control may be limited to a subset of data streams that support bit rate control. If so, a new signaling (e.g., MAC CE) is proposed to carry relevant information including the data stream index. In particular, the data stream index may be a relative data stream ID (such as a QoS stream index) rather than an absolute data stream ID, so that the size of the data stream index can be shortened.

[0062] Alternatively or additionally, in some example embodiments of this disclosure, the network may configure the validity period of the bit rate information, which may be used to instruct the UE to switch back to using the previous bit rate or the default bit rate once the timer expires (which may be configured by the network or defined in the specification).

[0063] Reference Figures 3A to 3C Discuss the above example embodiments, Figures 3A to 3C Signaling flows 300A to 300C of communications according to some embodiments of this disclosure are shown. For purposes of discussion, reference will be made, for example, to the use of the first device 110 and the second device 120. Figure 1 The signaling flows 300A to 300C are discussed, wherein the first device 110 can be used as a terminal device, and the second device 120 can be used as a network device. Note that... Figures 3A to 3C The sequence of actions shown is merely an example and not a limitation. Actions can be performed in any suitable manner. Reference Figures 3A to 3C The described example embodiments can be implemented individually or in any combination. For example, one or more example embodiments shown in a single figure can be combined with one or more example embodiments shown in one or more other figures.

[0064] Furthermore, it should be understood that the operations at the first device 110 and the second device 120 should be coordinated. In other words, the second device 120 and the first device 110 should have a common understanding regarding configuration, parameters, etc. Such a common understanding can be achieved through any suitable interaction between the second device 120 and the first device 110, or by both the second device 120 and the first device 110 applying the same rules, strategies, etc.

[0065] In the following description, although some operations are presented from the perspective of the first device 110, it should be understood that the corresponding operations should be performed by the second device 120. Similarly, although some operations are presented from the perspective of the second device 120, it should be understood that the corresponding operations should be performed by the first device 110. For the sake of brevity, some identical or similar content has been omitted here.

[0066] Reference Figure 3A This section discusses example implementations regarding pre-configured bit rate ranges.

[0067] In operation, such as Figure 3A As shown, the second device sends configuration information (302-1) indicating a bit rate range to the first device 110, and the first device 110 accordingly receives configuration information (302-2) from the second device 120. In some example embodiments, the configuration information may be included in at least one of the following: RRC signaling or MAC CE. It should also be noted that the configuration information may be included in a single message or multiple different messages.

[0068] In some example embodiments, the bit rate range is configured specific to at least one of the following: QoS stream, DRB, LCH, LCG, MMS, QoS stream set, DRB set, LCH set, LCG set, MMS set.

[0069] In some example embodiments, the bit rate range can be indicated by a bit rate index defined in a table comprising multiple entries, each entry indicating the correspondence between the bit rate index and the bit rate value. (See reference) Figure 2B To better understand. Figure 2B In the example, the table includes bit rate indices 250-1 and 250-2 and bit rate values ​​260-1 and 260-2.

[0070] In some example embodiments, the bit rate range may be indicated by at least one of the following: a maximum bit rate, a minimum bit rate, at least one allowed bit rate, or a number of allowed bit rates. As an example, the bit rate range may be... Figure 2B A subset of the bit rate index in the table.

[0071] It should be noted that, in addition to the bit rate index, as discussed below in this disclosure, the configuration information discussed herein may include other relevant information (such as effective duration information, multiplication factor, subset of the data stream set supporting bit rate control, etc.) that may also be included in the configuration information. For the sake of brevity only, some of the same or similar contexts will not be described again.

[0072] Then, the second device 120 may send a command (306-1) to the first device 110 (such as a MAC CE for bit rate control), and the first device 110 accordingly receives (306-2) the command. Specifically, the command may include data stream identification information of at least one data stream ID, wherein the at least one data stream may include at least one of the following: at least one Quality of Service (QoS) stream, at least one Data Radio Bearer (DRB), at least one Logical Channel (LCH), at least one Logical Channel Group (LCG), and at least one Multimodal Service (MMS). Alternatively or additionally, the command may include bit rate information to be applied to the at least one data stream. In particular, the bit rate information is based on a bit rate range.

[0073] As described above, as an example embodiment, the bit rate range may correspond to at least one bit rate index included in a table, wherein the table includes multiple entries, and each entry indicates the correspondence between the bit rate index and the bit rate value. If so, the bit rate information indicated by the command may be one of at least one bit rate index.

[0074] In some example embodiments, the bit rate range may correspond to at least one allowed bit rate, and the size of the bit rate index of the bit rate information may be determined based on the number of allowed bit rates corresponding to the bit rate range. For example, if the number of allowed bit rates is 8, the size of the bit rate index of the bit rate information may be 3 bits.

[0075] Optionally, command transmission can be conditionally executed. Specifically, in some example embodiments, the second device 120 can send commands to the first device 110 based on the detection (304) of uplink or downlink congestion.

[0076] According to the command, the first device 110 determines (308) the bit rate to be applied to the at least one data stream based at least in part on the bit rate information.

[0077] Additionally, to support higher bit rates, a multiplication factor can be applied. Specifically, in some example embodiments, the first device 110 can receive an indication from the second device 120 of the multiplication factor to be applied to the bit rate information, and then the bit rate can be determined based on the bit rate information and the multiplication factor.

[0078] In some example implementations, the multiplication factor may be included in the command.

[0079] Alternatively or additionally, the multiplication factor can be included in the configuration information. For example, the multiplication factor can be configured via RRC signaling and / or configured together with / separately with the bit rate range.

[0080] Additionally, the multiplication factor can be configured specific to at least one of the following: QoS flow, DRB, LCH, LCG, MMS, QoS flow set, DRB set, LCH set, LCG set, and MMS set. Furthermore, the configured multiplication factor can be different for different QoS flows, DRBs, LCHs, LCGs, MMS, different QoS flow sets, different DRB sets, different LCH sets, different LCG sets, and different MMS sets. For example, a first multiplication factor is configured for a first QoS flow (or a first group of QoS flows), and a different second multiplication factor is configured for a second QoS flow (or a second group of QoS flows).

[0081] Reference Figure 3B This section discusses example implementations regarding configuring the effective duration.

[0082] In operation, such as Figure 3B As shown, the second device 120 can send a command (326-1) to the first device 110 (such as a MACCE for bit rate control), and the first device 110 accordingly receives (326-2) the command. Specifically, the command may include data stream identification information for at least one data stream, wherein the at least one data stream may include at least one of the following: at least one Quality of Service (QoS) stream, at least one Data Radio Bearer (DRB), at least one Logical Channel (LCH), at least one Logical Channel Group (LCG), and at least one Multimodal Service (MMS). Alternatively or additionally, the command may include bit rate information to be applied to the at least one data stream.

[0083] Optionally, command transmission can be conditionally executed. Specifically, in some example embodiments, the second device 120 can send commands to the first device 110 based on the detection (324) of uplink or downlink congestion.

[0084] Then, the first device 110 may apply (328) the bit rate information to at least one data stream during the effective duration. Specifically, in some example embodiments, the first device 110 may apply a bit rate based on the bit rate information during the effective duration, and when the effective duration expires, the first device 110 may switch the bit rate to a previous bit rate or a default value. In some example embodiments, the default value may be configured by the second device 120 or a predefined value (such as a predefined value specified in 3GPP). In some other example embodiments, the first device 110 may apply (328) the bit rate information to at least one data stream until a new command is received from the second device 120. In other words, the length of the effective duration is the interval between two commands.

[0085] In this way, the application of bit rate control commands can be restricted by defining the effective duration, since congestion is usually temporary.

[0086] In some cases, the effective duration can be defined as a default configuration. As an example, the first device 110 can apply the bit rate based on the bit rate information for a predetermined duration since the command was received.

[0087] In some other cases, the effective duration can be configured by the second device 120. For example... Figure 3B As shown, the second device can send (322-1) configuration information indicating the effective duration to the first device 110, and the first device 110 can receive (322-2) configuration information accordingly.

[0088] In addition to the effective duration, the configuration information may also include a field indicating whether the effective duration should be applied by the first device 110. Note that, as stated above, the configuration information discussed herein may include other relevant information discussed in this disclosure.

[0089] In some example embodiments, the effective duration is configured specific to at least one of the following: QoS flow, DRB, LCH, LCG, MMS, QoS flow set, DRB set, LCH set, LCG set, and MMS set.

[0090] In some cases, when an effective duration is provided, the second device 120 may determine whether to apply the effective duration. Specifically, in some example embodiments, the command may include a field indicating whether the effective duration should be applied by the first device 110.

[0091] In some cases, when an effective duration is provided, whether to apply the effective duration can be determined by the first device 110. Specifically, in some example embodiments, the first device 110 may apply the configuration of the effective duration if the bit rate determined based on the bit rate information is less than or not greater than the bit rate currently applied for the indicated data stream. Alternatively or additionally, in some embodiments, the first device 110 may apply the configuration of the effective duration if the bit rate determined based on the bit rate information is less than or not greater than a threshold. Alternatively or additionally, in some embodiments, the first device 110 may apply the configuration of the effective duration if the data stream identification information corresponds to at least one of a specific QoS stream, a specific LCH, a specific LCG, a specific DRB, or a specific MMS.

[0092] Reference Figure 3C This section discusses example implementations of introducing relative data stream IDs.

[0093] In operation, such as Figure 3C As shown, the second device 120 can send a command (346-1) to the first device 110 (such as a MAC CE for bit rate control), and the first device 110 receives the command (346-2) accordingly. Optionally, the transmission of the command can be conditionally executed. Specifically, in some example embodiments, the second device 120 can send a command to the first device 110 based on the detection (344) of uplink congestion or downlink congestion.

[0094] exist Figure 3C In the example, the command may include data stream identification information for at least one data stream, wherein the at least one data stream may include at least one of the following: at least one Quality of Service (QoS) stream, at least one Data Radio Bearer (DRB), at least one Logical Channel (LCH), at least one Logical Channel Group (LCG), and at least one Multimodal Service (MMS). Alternatively or additionally, the command may include bit rate information to be applied to the at least one data stream. Specifically, the first device 110 is configured with a set of data streams, a subset of which supports rate control, and the data stream identification information is an identifier indexed in the subset rather than in the set.

[0095] In some example implementations, the size of the data stream identification information can be determined based on the number of data streams in the subset. For example, if the number of data streams in the subset is 8, then the size of the data stream identification information is 3 bits. This reduces signaling overhead.

[0096] In some example embodiments, the data stream identification information may be a first data stream identifier, which is determined by re-indexing the data streams included in the subset according to the ascending or descending order of a second data stream identifier, which is used to identify the data stream in the data stream set. For example, if QoS streams with QoS stream ID1, QoS stream ID4, and QoS stream ID7 are subject to rate control, the rate control signal uses relative index 1, relative index 2, and relative index 3 for QoS stream ID1, QoS stream ID4, and QoS stream ID7, respectively.

[0097] Upon receiving the command, the first device 110 determines (348) at least one data stream to which the bit rate information will be applied based on the data stream identification information.

[0098] In some cases, the IDs of data streams that support data rate control can be defined by default. For example, data stream IDs #0 to #7 can be assigned to data streams that support data rate control according to 3GPP standards.

[0099] In some other cases, the first device 110 may determine a subset of QoS flows and report that subset to the second device 120. Specifically, in some example embodiments, the first device 110 may send information about a subset of QoS flows to the second device 120.

[0100] In some other cases, a subset of QoS flows may be provided by the second device 120. Specifically, in some example embodiments, the first device 110 may receive configuration information (such as RRC / MAC CE) indicating a subset of QoS flows from the second device 120.

[0101] As mentioned above, the configuration information discussed herein may include other relevant information discussed in this disclosure.

[0102] For better understanding, some example operations for uplink bit rate control are discussed below.

[0103] In summary, for uplink rate control, it proposes to independently (e.g., via RRC or MAC CE) allocate a range of bit rates to QoS flows and / or indicate the applicable bit rate for QoS flows by using the relative order of QoS flow IDs. Alternatively or additionally, the network can set the effective duration of the bit rate information.

[0104] In some example implementations, the rate control signal can be a MAC CE. Furthermore, how congestion is detected and when the rate control signal is sent depends on the NW implementation.

[0105] In some example embodiments, for rate control operations, the gNB can provide bit rate range information to the UE. In some example embodiments, the bit rate range can be provided per QoS stream, LCH, LCG, DRB, or MMS. One option is to send the bit rate range for each stream, LCH, DRB, or MMS; another option is to send a set of streams, LCHs, DRBs, or MMS that can use a specific bit rate range.

[0106] In some example embodiments, the bitrate range may indicate a minimum bitrate and a maximum bitrate, or multiple bitrates. In some example embodiments, when indicating a bitrate index, a table of bitrate fields used for recommending a bitrate MACCE (i.e., ...) can be used. Figure 2B (See the table in the table). As an example, the bit rate range used for rate control can be indicated by indices 41 and 56 as the minimum and maximum bit rates.

[0107] In some example implementations, the bit rate range can be signaled via RRC or MAC CE, per QoS stream, LCH, LCG, DRB, or MMS.

[0108] In some example embodiments, the gNB may also provide a bit rate multiplier to indicate higher bit rates beyond the table.

[0109] In some example embodiments, whether multiplication occurs is also indicated via the X field in the MAC CE. However, when targeting XR applications with higher data rates, this dynamic determination (e.g., MAC CE) may not be necessary, and static configuration via RRC will be sufficient and even beneficial for a compact design of a new MAC CE for rate control.

[0110] In some example embodiments, when the gNB sends a rate control signal including bit rate information to the UE, the QoS flow to which the bit rate information will be applied may be indicated as follows.

[0111] In some example implementations, the size of the bit rate range field may be less than 5 bits, for example, 3 or 4 bits.

[0112] In some example embodiments, instead of the absolute value of the QoS flow ID, a relative order can be used. In some example embodiments, for example, the relative order can be an ascending order of the QoS flow IDs of the QoS flows to which rate control can be applied. For example, if a QoS flow with QoS flow ID 1, QoS flow ID 4, and QoS flow ID 7 is subject to rate control, then the rate control signal uses relative index 1, relative index 2, and relative index 3 for QoS flow ID 1, QoS flow ID 4, and QoS flow ID 7, respectively.

[0113] In some example embodiments, it can be assumed that the gNB and UE know which QoS flow(s) support rate control. In some example embodiments, the QoS flow index field may be less than 6 bits, for example, 3 or 4 bits.

[0114] In some example embodiments, the gNB can provide the UE with the validity period of the indicated bit rate information. In some example embodiments, the validity period value can be provided per QoS stream, LCH, LCG, DRB, or MMS.

[0115] In some example implementations, if a valid time value is not provided, the valid time may not be applied.

[0116] In some example embodiments, if a valid time value is provided, whether to apply the valid time can be further determined based on conditions. For example, the UE may apply the valid time in the following limited cases: when the indicated bit rate is lower than the bit rate currently used for the indicated QoS flow; when the indicated bit rate is lower than a configured threshold in terms of bit rate; when the indicated bit rate is applied to a specific QoS flow, LCH, LCG, DRB, or MMS.

[0117] In some example embodiments, the gNB can explicitly indicate whether a valid time is applied via a rate control signal, for example, using a valid time field in the MAC CE.

[0118] In some example implementations, when the gNB configures the UE using a rate control procedure, for example, when the gNB provides the UE with bit rate range information, it can provide the UE with a value for the effective time.

[0119] In some example embodiments, when the UE receives bit rate information for a QoS flow, the UE can apply the received bit rate information to the indicated QoS flow for the effective duration corresponding to the QoS flow (i.e., the UE applies the received bit rate information to the indicated QoS flow for the effective duration corresponding to the QoS flow).

[0120] In some example embodiments, when the effective time expires, the UE can switch back to using the previous bit rate or the default bit rate. In some example embodiments, the default bit rate can be configured by the gNB when the gNB configures the rate control procedure for the UE.

[0121] Now for reference Figure 4A and Figure 4B It shows two example MAC CE structures. Figure 4A In the example, MAC CE includes a 4-bit QoS flow index field and a 4-bit bitrate index field.

[0122] Additionally, in some example implementations, a bit rate multiplier can be pre-configured for QoS flows. If so, the bit rate indicated for the QoS flow is always multiplied by the multiplier.

[0123] Additionally, in some example embodiments, a valid duration / timer can be pre-configured for the QoS flow. If so, the UE can apply the valid duration / timer when the indicated bit rate is lower than the currently used bit rate. Alternatively, the UE determines whether to apply the valid duration based on other conditions as described above.

[0124] exist Figure 4B In the example, the MAC CE includes a 5-bit QoS flow index field. Similar to the recommended bitrate MAC CE, it includes a 6-bit bitrate index field and a 1-bit bitrate multiplier field to reuse the bitrate table defined for the recommended bitrate MAC CE.

[0125] Additionally, in some example embodiments, the MAC CE may include a V field, which is a validity period field. If it is set to 1, the UE applies the indicated bit rate to the corresponding QoS stream during the validity period. If it is set to 0, the UE continues to use the indicated bit rate for the corresponding QoS stream until it receives another bit rate information for the QoS stream from the gNB.

[0126] In some example embodiments, the rate control MAC CE is assigned a new LCID value that differs from the recommended bit rate MAC CE, for example, a value between 35 and 46, which is currently reserved for further use.

[0127] It is worth noting that the number of bits carrying QoS flow index information can also have other lengths, similar to the number of bits carrying bit rate index.

[0128] exist Figure 4A and Figure 4B In the example, although only one QoS flow is shown, the proposed MACCE can actually be extended to cover multiple QoS flows by including multiple information elements. It should be noted that, for illustrative purposes, in Figure 4A and Figure 4B The example uses QoS streams without implying any limitations. Relative indexes can also be applied to other data stream formats, such as LCH, LCG, DRB, or MMS for MAC CE.

[0129] According to example embodiments of this disclosure, the UE can dynamically adjust the bit rate and coding parameters of each QoS stream by taking into account the capabilities of the application layer to which the QoS stream belongs. Furthermore, the rate control signaling overhead can be reduced with the configurable bit rate range and effective time.
