Description

Communication method and communication apparatus

[0001] This application claims priority to the Chinese patent application No. 202411399560.9, filed on September 30, 2024, and entitled "Communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, and more particularly, to a communication method and a communication apparatus. BACKGROUND

[0003] In the fifth generation (5 th generation, 5G) system, the network can provide a certain air interface transmission rate guarantee for data transmission. Ideally, the data sending rate, i.e., the rate at which the data source delivers data to the network, matches the network transmission rate, which maximizes the utilization efficiency of network resources while guaranteeing user experience.

[0004] However, the actual network transmission rate fluctuates, which may vary with the number of available resources, congestion, channel quality, and other factors. The data source sending rate is less or not affected by these factors, and is usually stable, so in practice, the network transmission rate may be lower or higher than the data sending rate. When the transmission rate is lower than the sending rate, the data cannot be transmitted in time, resulting in increased latency or packet loss, affecting user experience. When the transmission rate is higher than the sending rate, the network resources may be idle, reducing resource utilization efficiency. Therefore, how the network device flexibly and accurately indicates the recommended rate to the terminal device is a problem to be solved in the field. SUMMARY

[0005] The present application provides a communication method and a communication apparatus, which can more flexibly and accurately indicate the recommended rate by dynamically indicating the rate multiplier by the network device.

[0006] In a first aspect, a communication method is provided. The method can be applied to a terminal device, i.e., the method can be executed by a terminal device, or can be executed by a component (such as a chip or a chip system or a circuit or a communication module or a processor) of the terminal device, which is not limited in the present application. Hereinafter, the terminal device will be mainly taken as an example for description.

[0007] The method can include: receiving first information, the first information indicating a first bit rate; receiving second information, the second information indicating a first value; determining a recommended data sending rate as a second bit rate, the second bit rate being determined based on the first value and the first bit rate.

[0008] Based on the technical solution, the terminal device can receive the first bit rate and the first value indicated by the network device, the network device can flexibly set and indicate the first value as needed, and then the terminal device can determine the recommended data sending rate according to the dynamically indicated first value and the first bit rate. Based on this, the network device can more flexibly and accurately indicate the recommended rate to the terminal device, the terminal device can more accurately determine the data sending rate, and then the terminal device can better match the data sending speed and the network transmission speed, thereby achieving the effects of reducing network transmission, reducing packet loss, and improving resource utilization efficiency.

[0009] Conversely, for example, the first value is a predefined or preconfigured static value, the number and value range of the recommended rate indicated by the network device to the terminal device are limited, and the recommended rate indicated by the network device to the terminal device is coarse and has poor flexibility and accuracy.

[0010] In combination with the first aspect, in some implementations of the first aspect, the second information indicates the first value, including: the second information includes the first value; or the second information includes a first index associated with the first value.

[0011] Based on the technical solution, the network device can directly indicate the value of the first value, or the network device can indirectly indicate the first value through an index, for example, the index can be associated with a configured or predefined table.

[0012] In combination with the first aspect, in some implementations of the first aspect, the second bit rate is determined based on the first value and the first bit rate, including: the second bit rate is the product of the first value and the first bit rate.

[0013] In combination with the first aspect, in some implementations of the first aspect, the method can further include: receiving third information, the third information indicating that the second bit rate is further determined based on a second value, and the second value is configured.

[0014] Based on the technical solution, the network device can indicate the terminal device that the second bit rate is further determined based on the second value, that is, the terminal device can determine the second bit rate in combination with the first bit rate, the first value, and the preconfigured second value, thereby further improving the flexibility of indicating the recommended rate.

[0015] In combination with the first aspect, in some implementations of the first aspect, the second bit rate is further determined based on the second value, including: the second bit rate satisfies: S2=S1 x f(n1, n2), where S2 represents the second bit rate, S1 represents the first bit rate, n1 represents the first value, and n2 represents the second value.

[0016] In a second aspect, a communication method is provided.

[0018] Based on the above technical solution, the terminal device can report one or more bit rates to the network device through the fourth information, and the network device can determine and send a third bit rate as a recommended data sending rate, the third bit rate belonging to the one or more bit rates. Based on this, the network device can accurately indicate the recommended rate within the rate range provided by the terminal device according to the business needs of the terminal device itself, so that the recommended rate indicated by the network device matches the optional rate of the terminal device itself, and then the terminal device effectively adjusts the rate.

[0019] Alternatively, based on the above technical solution, the network device can configure a dedicated rate range for the terminal device through the fourth information, and indicate a third bit rate as a recommended data sending rate through the fifth information based on the dedicated rate range. Based on this, by configuring the rate range by the network device, the recommended rate indicated by the network device can be more specific and accurate, and then the terminal device effectively adjusts the rate.

[0020] In combination with the second aspect, in some implementations of the second aspect, the fourth information indicating the one or more bit rates includes: the fourth information indicating a minimum value and a maximum value in the one or more bit rates, the minimum value and the maximum value being used to determine the one or more bit rates.

[0021] Based on the above technical solution, the network device or the terminal device can indicate one or more bit rates only through the maximum value and the minimum value, thereby reducing the signaling overhead.

[0024] Based on the above technical solution, the network device or the terminal device can indicate the minimum value and the maximum value in the one or more bit rates by using only one index, and then indicate the recommended rate range.

[0083] The technical solutions in the present application will be described below with reference to the drawings.

[0084] Before introducing the solutions of the present application, the following points are explained.

[0085] (1) In the present application, "indication" can include direct indication, indirect indication, explicit indication, implicit indication, etc. When describing that a certain indication information indicates A, it can be understood that the indication information carries A, carries an identifier of A, carries B having a correlation with A, carries an identifier of B having a correlation with A, etc. In other words, if the receiving side of certain indication information can determine A according to the indication information, it can be described that the indication information indicates A, and the specific determination manner is not limited. When it is understood that the indication information carries A, "indication" can be replaced by "includes", and at this time, similar to the expression "sending / receiving indication information, the indication information indicates A", the expression can be replaced by "sending / receiving A".

[0086] In the present application, the information indicated by the indication information is referred to as to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information, etc. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information has a correlation with the to-be-indicated information. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be realized by means of the arrangement order of each information agreed in advance (for example, a protocol stipulates), thereby reducing the indication overhead to a certain extent. In addition, the to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending occasion of these sub-information can be the same or different.

[0087] (2) In this application, the expression " / " is used to represent the relationship of "or" between the objects associated in front and back; for example, A / B can represent: A or B. The expression "and / or" is used to represent the relationship of both and or or between the objects associated in front and back; for example, A and / or B can represent the following cases: A exists alone, B exists alone, A and B exist together, wherein A, B can be single or multiple. "At least one of the following" or similar expressions are used to represent any combination of the listed items; for example, at least one of A, B and (or) C can represent the following cases: A exists alone, B exists alone, C exists alone, A and B exist together, B and C exist together, A and C exist together, A, B and C exist together, wherein A, B, C can be single or multiple.

[0088] (3) In this application, "send" and "receive" represent the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information being XX, which can include direct transmission through the air interface, or indirect transmission through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information being YY, which can include direct reception from YY through the air interface, or indirect reception from YY through the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0089] (4) In various embodiments of the present application, the terms and / or descriptions of different embodiments are consistent and can be mutually referenced if there is no special description and logical conflict. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0090] (5) In this application, "first", "second" are only for convenience of description, used to distinguish the objects, and not used to limit the scope of the embodiments of the present application. It should be understood that the objects thus described can be interchanged under appropriate circumstances in order to describe solutions other than the embodiments of the present application.

[0091] (6) In this application, "predefined" can mean standard protocol predefined, or can also mean pre-agreed or pre-negotiated between devices. Among them, "protocol" can refer to standard protocols in the communication field, which can include fourth generation (4 th generation, 4G) network, fifth generation (5th In this application, the new radio (NR) protocol, the 5.5G network protocol, the future communication network protocol, and the related protocol applied in the future communication system are not limited.

[0092] (7) In this application, the words such as "exemplarily", "for example" and the like are used to represent examples, illustrations or descriptions. Any embodiment or design scheme described as "example" in this application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the word "example" is used to present the concept in a specific way. In the embodiments of this application, "of", "corresponding" and "corresponding" are sometimes mixed. It should be pointed out that when the difference is not emphasized, the meanings expressed are consistent.

In other examples, the helicopter or the drone can be configured to act as a device communicating with another base station.

[0105] In some deployments, a plurality of RAN nodes cooperate to assist a terminal device to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a CU, a DU, a CU-CP, a CU-UP, or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can also be included in the same network element, such as a BBU.

[0109] Referring to FIG. 1, FIG. 1 is a schematic diagram of a communication architecture suitable for the embodiments of the present application. In the present application, the embodiments of the present application are described by taking a 5G base station as an example. As shown in FIG. 1, in the 5G system, the base station is referred to as gNB / ng-eNB, mainly including radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP), radio link control (RLC), medium access control (MAC) and physical layer (PHY), which can be collectively represented by gNB, and the gNBs are connected through an Xn interface. The gNB and the 5G core network are connected through an NG interface. In some deployments, the gNB can be composed of a CU and a DU, that is, the functions of the base station in the original access network are split, part of the functions of the base station are deployed in a CU, and the remaining functions are deployed in a DU, multiple DUs share one CU, which can save cost and facilitate network expansion. The split of the CU and the DU can be according to the protocol stack, and one possible way is to deploy the RRC, SDAP and PDCP layers in the CU, and the remaining RLC, MAC and PHY in the DU. The CU and the DU are connected through an F1 interface. The CU represents the gNB to connect with the core network through the NG interface, the CU represents the gNB to connect with other gNBs through the Xn interface, and the CU can also represent the gNB to connect with other eNBs through the X2 interface to perform a dual connection operation.

[0110] Referring to FIG. 2, FIG. 2 is a schematic diagram of a base station CU-DU separation architecture suitable for embodiments of the present application. As shown in FIG. 2, the CU can also be divided into a control plane (CU-CP) and a user plane (CU-UP).

The user plane of the CU, i.e., F1-U, is connected with the DU through an F1 interface. Of course, there is also a possible implementation that the PDCP-C is also in the CU-UP.

[0111] Referring to FIG. 3, FIG. 3 is a schematic diagram of a 5G XR communication architecture suitable for embodiments of the present application. Exemplarily, in FIG. 3, for a service, the following behaviors, data is generated by an application server, forwarded through a data network (Data Network, DN), sent to the core network through an N6 interface, the core network transmits data to the base station through an N3 interface, and the base station sends data to the UE through a Uu air interface. In addition, for sidelink (SL) communication, communication is carried out between user communication devices (e.g., XR devices) and user communication devices (e.g., XR devices).

[0112] It can be understood that FIG. 3 is only an example and is not a limitation on the application scenarios to which the present application is applied. Among them, the core network device refers to a device in the core network (CN) that provides service support for the terminal. At present, some examples of core network devices are: access and mobility management function (AMF) entity, session management function (SMF) entity, user plane function (UPF) entity, and the like, which are not listed one by one here. Among them, the AMF entity can be responsible for access management and mobility management of the terminal; the SMF entity can be responsible for session management, such as session establishment of a user; and the UPF entity can be a functional entity of the user plane, mainly responsible for connecting external networks. It should be noted that the entity in the present application can also be referred to as a network element or a functional entity, for example, the AMF entity can also be referred to as an AMF network element or an AMF functional entity, and for another example, the SMF entity can also be referred to as an SMF network element or an SMF functional entity, and the like.

[0113] For the convenience of understanding the embodiments of the present application, the terms involved in the present application are briefly explained.

[0114] 1. Access network bitrate recommendation (ANBR):

[0115] In the 5G system, the network device can provide a certain air interface transmission rate guarantee for data transmission. Ideally, the sending rate of data, i.e., the rate at which the data source delivers data to the network, matches the transmission rate of the network, which can maximize the utilization efficiency of network resources and at the same time guarantee the user experience.

[0116] However, the actual transmission rate of the network fluctuates, and this speed can change with the number of available resources, congestion conditions, channel quality, and other factors. The sending rate of the data source is less affected or not affected by these factors, and is usually stable, so in practice the network transmission rate can be lower or higher than the data sending rate. When the transmission rate is lower than the sending rate, the data cannot be transmitted in time, resulting in increased latency or packet loss, affecting the user experience. When the transmission rate is higher than the sending rate, the network resources can be idle, and the resource utilization efficiency is reduced.

[0117] To make the data sending rate more match the network transmission rate, ANBR supports network device to indicate recommended rate to terminal device. In response to the network device recommendation, the terminal device can adjust the uplink (UL) or downlink (DL) sending rate to a suitable level (downlink terminal device needs to inform the application server or inform the peer terminal device to adjust the rate), so as to match the network transmission rate. Correspondingly, the terminal device can also actively indicate the data sending rate expected by the terminal device to the network device.

[0118] Referring to FIG. 4, FIG. 4 is a medium access control control element (MAC CE) format applicable to the embodiments of the present application. In the ANBR technology, the network device can send the MAC CE in the format as shown in FIG. 4 to indicate the recommended rate. Among them, the logical channel identifier (LCID) can represent the identifier of the logical channel (LCH) to which the indicated recommended rate is directed; the uplink / downlink field can represent that the indicated recommended rate is directed to uplink or downlink; the bit rate field can correspond to the index in Table 1, which can be used to indicate the corresponding ANBR; the reserve field, also called R field, has no actual meaning. When the terminal device indicates the rate expected by the terminal device to the network device, the MAC CE format as shown in FIG. 4 can also be used.

[0119] Table 1

[0120] Table 1 is a possible ANBR recommended rate table, and the new radio recommended bit rate value corresponding to the index 0 in Table 1 is empty, which can be used to indicate that no new bit rate suggestion is given.

[0121] 2, Rate multiplier:

[0122] Since the recommended rate range defined by the above Table 1 is only 0-8 Mbps, ANBR can not be applicable to services with higher rates. To solve this problem, the network device can configure a rate multiplier for the terminal device, for example, the value of the rate multiplier can be 40, 70, 100 or 200.

[0123] Referring to FIG. 5, FIG. 5 is another MAC CE format applicable to the embodiments of the present application. Specifically, in order to use the rate multiplier, the MAC CE format of ANBR can be modified to the format shown in FIG. 5, in which an X field is added. The X field indicates whether the recommended rate uses the rate multiplier. For example, when X takes the value 1, it can indicate that the multiplier is used, in which case the recommended rate indicated by the MAC CE is the product of the rate corresponding to the bit rate field and the multiplier; when X takes the value 0, it can indicate that the multiplier is not used, in which case the recommended rate indicated by the MAC CE is the rate corresponding to the bit rate field. After the multiplier is added, the range of the recommended rate that can be indicated is expanded. For example, when the multiplier 40 is used, according to Table 1 above, the recommended rate can be indicated in the range of 0-320 Mbps.

[0124] One possible implementation can expand the range of the recommended rate that can be indicated by using the rate multiplier, thereby supporting rate adjustment of high-rate services. However, after the range of the indicated rate is expanded, the ANBR MAC CE can still only indicate 55 recommended rates, which results in a coarse granularity of the recommended rate, making it difficult for the network device to indicate an accurate recommended rate.

[0125] For example, assume that the transmission rate of a service can be adjusted among the rates of 300, 305, 310, 315, and 320 Mbps, and the network device needs to use the rate multiplier to indicate the recommended rate. Assume that the multiplier 40 is used. In this case, in Table 1, index 55 corresponds to the rate 300 Mbps, and index 56 corresponds to the rate 320 Mbps, which means that the network device cannot indicate the rates of 305, 310, and 315 Mbps when indicating the recommended rate. Similarly, the terminal device can only indicate the rates of 300 and 320 Mbps when indicating the expected rate to the network device. In this case, the network device cannot accurately indicate the real recommended rate, cannot make the transmission rate really reach the expectation, and still can affect the user experience or network efficiency.

[0126] Therefore, the present application proposes that the network device dynamically indicates the rate multiplier, and more flexibly and accurately indicates the recommended rate.

[0127] The method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments provided by the present application can be applied to the scenarios shown in the above figures, without limitation.

[0128] Referring to FIG. 6, as an example, FIG. 6 is a schematic diagram of a communication method 600 provided by the embodiments of the present application. For ease of description, the terminal device and the network device are taken as examples for illustrative description. The terminal device can be replaced by a component (for example, a chip or a chip system or a circuit or a communication module or a processor) of the terminal device, and the network device can be replaced by a component (for example, a chip or a chip system or a circuit or a communication module or a processor) of the network device. In addition, the steps described below as performed by a single execution subject can also be divided into steps performed by multiple execution subjects, which can be logically and / or physically separated. The method 600 shown in FIG. 6 can include the following steps.

[0129] S610, the network device sends first information. Correspondingly, the terminal device receives the first information. The first information indicates a first bit rate.

[0130] As an example, the bit rate can be used to represent the number of bits transmitted per unit time, the first bit rate can be used to determine the rate at which the network device recommends the terminal device to send data, and the first bit rate can also be referred to as a recommended rate, etc., and the naming does not limit the protection scope of the embodiments of the present application.

[0131] For example, the first bit rate can be 7.5 Mbps, which can be used to indicate that the network device recommends the terminal device to send data at a rate of 7.5 Mbps.

[0132] Referring to FIG. 7, as an example, FIG. 7 is a MAC CE format provided by the embodiments of the present application.

[0133] As an example, the first information can be carried in the MAC CE as shown in FIG. 7, wherein the first information can indicate the first bit rate through a first bit rate field, and the name of the first bit rate field is only an example, and the embodiments of the present application do not limit the field name.

[0134] Optionally, the first bit rate field can indicate the first bit rate through the table 1 described above. For example, the first bit rate field can include an index 55, according to the association relationship of the table 1, the index 55 can indicate that the first bit rate is 7.5 Mbps.

[0135] Optionally, the first bit rate field can indicate the first bit rate through other rate tables. For example, the other rate table can be a table redefined according to the service type.

[0136] Optionally, the first bit rate field can include a value of the first bit rate, or in other words, the first bit rate field can directly indicate the value of the first bit rate. The value of the first bit rate can be in units of Mbps or Kbps or other units, for example, the first bit rate field can directly indicate that the value of the first bit rate is 7.5 Mbps.

[0137] In addition, in the MAC CE format shown in FIG. 7, the logical channel identifier field can indicate the identity of the LCH to which the first information is directed, or the quality of service flow identifier (QFI) field can indicate the quality of service flow (QoS) to which the first information is directed, or the data radio bearer identifier (DRB ID) field can indicate the DRB.

[0138] In addition, in the MAC CE format shown in FIG. 7, the uplink / downlink field can indicate that the direction of the transmitted data to which the first information is directed is uplink or downlink.

[0139] S620, the network device transmits second information. Correspondingly, the terminal device receives the second information. The second information indicates the first value.

[0140] Optionally, the second information and the first information can respectively indicate the first value and the first bit rate. For example, the second information and the first information can be carried in different signaling.

[0141] Optionally, the network device can indicate the first value and the first bit rate in the same indication information, or in other words, the network device can indicate the first value when indicating the first bit rate. For example, the second information and the first information can be carried in the MAC CE in the format shown in FIG. 7, or in other words, the network device can transmit the MAC CE in the format shown in FIG. 7, which includes a first value field and a first bit rate field for indicating the first value and the first bit rate respectively.

[0142] As an example, the first value can be used to indicate the second bit rate in combination with the first bit rate, or in other words, the first value and the first bit rate are used to determine the second bit rate, which is the recommended data transmission rate. The first value can also be referred to as a first parameter or a first multiplier or a rate multiplier, etc., and the naming does not limit the protection scope of the embodiments of the present application.

[0143] As an example, the recommended data sending rate can include a rate at which the network device recommends the terminal device to submit data to the network, for example, the ANBR described above. The recommended data sending rate can also be referred to as a suggested data sending rate or a guided data sending rate, or, in order to distinguish from the first bit rate (recommended rate), the recommended data sending rate can also be referred to as an actual recommended rate, and the naming does not limit the protection scope of the embodiments of the present application.

[0144] It should be understood that the specific manner in which the first value and the first bit rate are used to determine the second bit rate will be described later with respect to S630, and the embodiments of the present application will not be described here.

[0145] As an example, the second information indicates the first value, and it can also be understood that the second information includes a first value field for indicating the first value.

[0146] Optionally, the second information indicates the first value, including that the second information includes the first value. Or, the second information directly indicates the numerical value of the first value. For example, please continue to refer to FIG. 7, the second information is carried in the MAC CE in the format shown in FIG. 7, and the first value field shown in FIG. 7 directly indicates that the numerical value of the first value is 4.

[0147] Optionally, the second information indicates the first value, including that the second information includes a first index associated with the first value.

[0148] As an example, the first index can be associated with the first value through a first list, and the first list can include one or more optional first values. Wherein, the first list can also be referred to as a first value list or a first parameter list or a first multiplier list or a rate multiplier list or a candidate list, and the naming does not limit the protection scope of the embodiments of the present application.

[0149] Optionally, the first list can be pre-configured.

[0150] For example, the first list can be {35, 36, 37, 38, 39, 40, 41, 42}, please continue to refer to FIG. 7, the second information is carried in the MAC CE in the format shown in FIG. 7, and the first value field shown in FIG. 7 indicates that the first index is 7, which can represent the 8th value in the first list, that is, indicating that the first value is 42.

[0151] In the embodiments of the present application, the network device can directly indicate the value of the first value, or the network device can indirectly indicate the first value through an index, for example, the index can be associated with a configured or predefined table.

[0152] S630, the terminal device determines that the recommended data sending rate is a second bit rate, which is determined based on the first value and the first bit rate.

[0153] Specifically, the terminal device determines that the data transmission rate recommended by the network device is the second bit rate. Wherein, the "recommended data transmission rate" can also be replaced by any of the following: data transmission rate, indicated data transmission rate.

[0154] As a possible implementation manner, the second bit rate is determined based on the first value and the first bit rate, including: the second bit rate is the product of the first value and the first bit rate.

[0155] For example, the first information indicates that the first bit rate is 7.5 Mbps, and the second information indicates that the first value is 42, which can indicate that the second bit rate is 315 Mbps. Wherein, the specific indication manner of the first bit rate and the first value can refer to any of the indication manners described in the foregoing.

[0156] For example, the first information and the second information are carried in the MAC CE in the format shown in FIG. 7, the first information includes a first bit rate field, the first bit rate field takes the value 55, which corresponds to the index 55 of the table 1 described in the foregoing, indicating that the first bit rate is 7.5 Mbps. The second information includes a first value field, the first value field takes the value 4. Based on the above first bit rate and first value, the terminal device can determine that the data transmission rate recommended by the network device is 7.5*4=30 Mbps.

[0157] For another example, the first information and the second information are carried in the MAC CE in the format shown in FIG. 7, the first information includes a first bit rate field, the first bit rate field takes the value 55, which corresponds to the index 55 of the table 1 described in the foregoing, indicating that the first bit rate is 7.5 Mbps. A first list {35, 36, 37, 38, 39, 40, 41, 42} is pre-configured, the second information includes a first value field, the first value field takes the value 7, indicating the 8th value in the first list, i.e. indicating that the first value is 42. Based on the above first bit rate and first value, the terminal device can determine that the data transmission rate recommended by the network device is 7.5*42=315 Mbps.

[0158] In the embodiment of the application, the terminal device can receive the first bit rate and the first value indicated by the network device, the network device can flexibly set and indicate the first value as needed, and then the terminal device can determine the recommended data transmission rate according to the dynamically indicated first value and the first bit rate. Based on this, the network device can more flexibly and accurately indicate the recommended rate to the terminal device, the terminal device can more accurately determine the data transmission rate, and then the terminal device can better match the data transmission speed and the network transmission speed, thereby achieving the effect of reducing network transmission, reducing packet loss and improving resource utilization efficiency.

[0159] Conversely, for example, the first value is a predefined or preconfigured static value, the number and value range of the recommended rate indicated by the network device to the terminal device are limited, and the recommended rate indicated by the network device is coarse in granularity, poor in flexibility and accuracy.

[0160] It should be noted that the above examples are mainly used to make it easier for the reader to understand the content of the embodiments of the present application, the specific manner in which the network device indicates the first bit rate and the first value is not limited by the embodiments of the present application, and the manner in which the second bit rate is determined based on the first bit rate and the first value is also not limited by the embodiments of the present application. For example, the second bit rate can also be determined by adding or subtracting or dividing the first bit rate and the first value.

[0161] As a possible implementation manner, the method 600 can further include that the network device sends third information. Correspondingly, the terminal device receives the third information. Wherein, the third information indicates that the second bit rate is further determined based on a second value, and the second value is configured.

[0162] As an example, the second value can be a configured or predefined value, and the second value can be used to determine the second bit rate together with the first bit rate and the first value. Wherein, the second value can also be referred to as a second parameter or a second multiplier or a semi-static rate multiplier, etc., and the naming does not limit the protection scope of the embodiments of the present application.

[0163] Optionally, the third information can be distinguished from the first information and / or the second information, and separately indicates whether the second bit rate is further determined based on the second value. For example, the third information can be carried in signaling different from the first information and / or the second information.

[0164] Optionally, the network device can indicate the third information, the first value and / or the first bit rate in the same indication information. For example, based on the MAC CE format shown in FIG. 7, an X field can also be included to indicate whether the second bit rate is further determined based on the second value.

[0165] As an example, the third information can include 1 bit of data. For example, X is 1 to indicate that the second bit rate is further determined based on the second value, and X is 0 to indicate that the second bit rate is not determined based on the second value; or X is 0 to indicate that the second bit rate is further determined based on the second value, and X is 1 to indicate that the second bit rate is not determined based on the second value.

[0166] As an example, it can be predefined that the second bit rate is further determined based on the second value. For example, when the network device sends the MAC CE in the format shown in FIG. 7, it can be defaulted that the second bit rate is further determined based on the second value.

[0167] Based on the technical solution, the network device can indicate the terminal device to determine the second bit rate based on the third information and the second value, that is, the terminal device can determine the second bit rate in combination with the first bit rate, the first value and the preconfigured second value, thereby further improving the flexibility of indicating the recommended rate.

[0168] As an example, the second bit rate is determined based on the second value, which can also be understood as the first value can be used in combination with the second value to determine the second bit rate.

[0169] As an example, the second bit rate is determined based on the second value, which can also be understood as the first value can be used in combination with the second value to determine the second bit rate.

[0170] As an example, the second bit rate is determined based on the second value, which can also be understood as the first value can be used in combination with the second value to determine the second bit rate.

[0171] As an example, f(n1, n2) = n1 + n2. The network device can configure the second value as 40 through RRC, and then when indicating the second bit rate using the MAC CE in the format shown in FIG. 7, if the first bit rate field indicates that the first bit rate is 7.5 Mbps and the first value field indicates that the first value is 2, the second bit rate can be 7.5*(2+40) = 315 Mbps.

[0172] It should be noted that the above examples are mainly used to make it easier for the reader to understand the content of the embodiments of the present application, and the embodiments of the present application do not limit the combination of the first value and the second value, f(n1, n2). For example, the combination of the first value and the second value can also be f(n1, n2) = n2 - n1, and the embodiments of the present application do not limit this.

[0173] It should be further noted that the foregoing mainly takes the network device indicating the recommended data transmission rate to the terminal device as an example for description. In addition, the terminal device can also indicate the expected data transmission rate to the network device through the same or similar manner, and the specific indication manner can be analogously referred to the content described in the foregoing, and the embodiments of the present application will not be described herein.

[0174] Referring to FIG. 8, as an example, FIG. 8 is a schematic diagram of a communication method 800 provided by an embodiment of the present application. The method 800 shown in FIG. 8 can include the following steps.

[0175] S810, the terminal device sends or receives fourth information. Correspondingly, the network device receives or sends the fourth information. The fourth information indicates one or more bit rates.

[0176] In the following, the specific implementation manner when the fourth information is sent by the terminal device or the network device is illustrated by way of example 1 and example 2.

[0177] In a first manner, the terminal device sends fourth information. Correspondingly, the network device receives the fourth information.

[0178] As an example, the fourth information can indicate one or more bit rates determined by the terminal device, which can be referred to as a rate range hereinafter for ease of description, and the terminal device can report the rate range to the network device. The rate range can be for the terminal device, or for a QoS flow, or an LCH, or a DRB associated with the terminal device. In addition, the rate range can be for uplink and / or downlink.

[0179] As an example, correspondingly, the network device can determine a specific rate indication table according to the fourth information, so that when indicating a recommended data transmission rate subsequently, the network device can refer to the table for indication to match the possible transmission rate of the terminal device.

[0180] As a first possible implementation, the fourth information indicating one or more bit rates includes that the fourth information includes a value of the one or more bit rates. This implementation can also be understood as that the terminal device directly reports a specific bit rate level. For example, the fourth information includes the following values of bit rates: {300, 305, 310, 315, 320, 325, 330, 335}, and the unit of the bit rate can be Mbps.

[0181] As an example, correspondingly, the network device can determine a rate table as shown in Table 2, and when indicating a recommended rate, the network device can indicate indexes 0 to 7 to correspond to rates 300 Mbps to 335 Mbps.

[0182] Table 2

[0183] As a second possible implementation, the fourth information indicating one or more bit rates includes that the fourth information indicates a minimum value and a maximum value in the one or more bit rates, and the minimum value and the maximum value are used to determine the one or more bit rates. For example, the fourth information indicates that the minimum value in the one or more bit rates is 300 Mbps and the maximum value is 335 Mbps. Correspondingly, the recommended data transmission rate determined by the network device can be greater than or equal to 300 Mbps and less than or equal to 335 Mbps.

[0184] In the embodiments of the present application, the terminal device can indicate one or more bit rates only by the maximum value and the minimum value, thereby reducing signaling overhead.

[0185] As an example, the minimum value and the maximum value are used to determine the one or more bit rates, including that the one or more bit rates are N bit rates between the minimum value and the maximum value, and N is a positive integer.

[0186] For example, N equals 8, assuming the rate range is linearly divided into 8 bins, the network device can also determine the rate table as shown in Table 2.

[0187] Optionally, the value of N can be predefined, or in other words, the number of bins for dividing the rate range can be predefined. For example, the network device uses 3 bits to indicate the recommended rate, which can indicate up to 8 bins, or in other words, the number of bins for dividing the rate range is up to 8.

[0188] It should be noted that the above examples are mainly described in a linear manner, and the bin division can also be in a non-linear manner, for example, the bins can be divided according to an exponential distribution, which is not limited by the embodiments of the application.

[0189] In a possible implementation, the fourth information indicates the minimum and maximum of the one or more bit rates, including: the fourth information includes the value of the minimum and the maximum, or in other words, the fourth information directly indicates the value of the minimum and the maximum, or in other words, the terminal device directly reports the value of the minimum and the maximum.

[0190] For example, the fourth information can include the following bit rate values: {300, 335}, which can be in Mbps, indicating that the minimum of the one or more bit rates is 300 Mbps and the maximum is 335 Mbps.

[0191] In another possible implementation, the fourth information indicates the minimum and maximum of the one or more bit rates, including: the fourth information includes an index of the minimum and an index of the maximum, and the index of the minimum and the index of the maximum are respectively associated with the value of the minimum and the value of the maximum.

[0192] For example, the fourth information can include the following indexes: {35, 56}, which can be associated with the value of the minimum of 1 Mbps and the value of the maximum of 8 Mbps through the aforementioned Table 1.

[0193] In yet another possible implementation, the fourth information includes a second index, and the fourth information indicates the minimum and maximum of the one or more bit rates, including: the fourth information indicates a third index and a fourth index associated with the minimum and the maximum, and the third index and / or the fourth index are determined according to the second index and a first parameter (parameter #1), and the first parameter is configured or predefined.

[0194] It should be understood that in the possible implementation, the first parameter used to determine the third index and / or the fourth index is different from the first parameter used to replace the first value name described above. For ease of illustration, hereinafter, the first parameter used to determine the third index and / or the fourth index is denoted as parameter #1.

[0195] As an example, the fourth information includes the second index, and it can also be understood that the terminal device can only report one index to indicate the rate range.

[0196] As a possible implementation, the third index and the fourth index are determined according to the second index and the parameter #1, and include: the third index is the second index minus the parameter #1, and the fourth index is the second index plus the parameter #1.

[0197] As an example, the second index can be denoted as index A, and the fourth information including the second index can indicate the rate range corresponding to index(A-L) to index(A+L), where L can represent the value of the parameter #1.

[0198] For example, A=48, L=1, the second index can be denoted as index48, the third index can be denoted as index47, and the fourth index can be denoted as index49. The second index to the fourth index can be associated with the bit rate through the table 1 described above, and then the rate range indicated by the second index A=48 can be 3.5Mbps to 4.5Mbps.

[0199] As another possible implementation, the third index and the fourth index are determined according to the second index and the parameter #1, and include: the third index is the second index minus the parameter #1, and the fourth index is the second index.

[0200] As an example, the second index can be denoted as index A, and the fourth information including the second index can indicate the rate range corresponding to index(A-L) to index A, where L can represent the value of the parameter #1.

[0201] For example, A=48, L=1, the second index can be denoted as index48, the third index can be denoted as index47, and the fourth index can be denoted as index48. The second index to the fourth index can be associated with the bit rate through the table 1 described above, and then the rate range indicated by the second index A=48 can be 3.5Mbps to 4Mbps.

[0202] As another possible implementation, the third index and the fourth index are determined according to the second index and the parameter #1, and include: the third index is the second index, and the fourth index is the second index plus the parameter #1.

[0203] As an example, the second index can be denoted as index A, and the fourth information including the second index can denote a rate range corresponding to index A to index (A+L), where L can denote a value of the parameter #1.

[0204] For example, A=48, L=1, the second index can be denoted as index 48, the third index can be denoted as index 48, and the fourth index can be denoted as index 49. The second index to the fourth index can be associated with a bit rate through Table 1 described above, and thus the rate range indicated by the second index A=48 can be 4Mbps to 4.5Mbps.

[0205] In the embodiments of the present application, the terminal device can indicate the minimum value and the maximum value in the one or more bit rates by only one index, and further indicate the recommended rate range. Based on this, the signaling overhead for indicating the recommended rate range can be further reduced.

[0206] Optionally, the parameter #1 can be predefined or configured by the network device.

[0207] As a possible implementation manner, the rate range is further determined according to a rate multiplier.

[0208] Optionally, the rate multiplier can be pre-configured by the network device, or the rate multiplier can be reported by the terminal device to the network device.

[0209] For example, when the index is reported to the network device to indicate the rate range by using Table 1 described above, the rate multiplier can be combined, for example, the terminal device reports index 50 of Table 1 to indicate the rate range, and indicates that the rate multiplier 40 is used. Assuming that L=1, according to the possible implementation manner described above, the rate range indicated by index 50 can be 200~220Mbps or 180~200Mbps or 180~220Mbps.

[0210] S820, the network device sends the fifth information. Correspondingly, the terminal device receives the fifth information. Wherein, the fifth information indicates a third bit rate, the third bit rate belongs to the one or more bit rates, and the third bit rate is a recommended data sending rate.

[0211] As an example, the fifth information can be carried in the MAC CE, and the third bit rate is indicated by the recommended rate field in the MAC CE.

[0212] As an example, the third bit rate belongs to the one or more bit rates, which can be understood as that the network device indicates the third bit rate in the rate range after obtaining the rate range reported by the terminal device.

[0213] For example, the network device determines the rate range as shown in Table 2, and the network device accurately indicates the third bit rate by indicating indexes 0 to 7 to the terminal device.

[0214] In the embodiments of the present application, the terminal device can report one or more bit rates to the network device through the fourth information, and the network device can determine and send a third bit rate as a recommended data sending rate, the third bit rate belonging to the one or more bit rates. Based on this, the network device can accurately indicate the recommended rate within the rate range provided by the terminal device according to the service needs of the terminal device itself, so that the recommended rate indicated by the network device matches the optional rate of the terminal device itself, and then the terminal device effectively adjusts the rate.

[0215] It should be noted that the network device determines the rate table as shown in Table 2 described above can be considered as the internal implementation operation of the network device, and the network device actually does not necessarily need to display the determined rate table, and the network device can only indicate the third bit rate based on the logic described in the embodiments of the present application according to the content reported by the terminal device.

[0216] Optionally, before S810, the method 800 can further include that the network device sends information #A, and correspondingly, the terminal device receives the information #A, the information #A being used to indicate the terminal device to send the fourth information. That is, before obtaining the rate range, the network device can send an indication information to the terminal device to indicate the terminal device to report the rate range.

[0217] Optionally, after S810, the method 800 can further include that the terminal device sends information #B, and correspondingly, the network device receives the information #B, the information #B being used to indicate the expected rate of the terminal device, the expected rate belonging to the rate range reported by the terminal device.

[0218] Optionally, after S810, the method 800 can further include that the terminal device sends information #B, and correspondingly, the network device receives the information #B, the information #B being used to indicate the expected rate of the terminal device, the expected rate belonging to the rate range reported by the terminal device.

[0219] As an example, the fourth information can indicate the one or more bit rates determined by the network device, or in other words, the fourth information can indicate the rate range determined by the network device, and the network device can configure the rate range to the terminal device. Wherein, the rate range can be for the terminal device, or for the QoS flow or LCH or DRB associated with the terminal device. In addition, the rate range can be for uplink and / or downlink.

[0220] As an example, the network device can configure multiple rate bins, or the network device can configure a minimum value and a maximum value of a rate range. For example, the network device can determine the minimum value and the maximum value of the rate range corresponding to the QoS flow according to a guaranteed flow bit rate (GFBR) and a maximum flow bit rate (MFBR) of the QoS flow. These information can be used for the fourth information to determine a specific rate indication table, so that when indicating the recommended data sending rate later, the network device can refer to the table to indicate the rate that can match the possible sending rate of the terminal device.

[0221] As a first possible implementation, the fourth information indicating one or more bit rates includes that the fourth information includes a value of one or more bit rates. This implementation can also be understood as that the network device directly configures specific bit rate bins. For example, the fourth information includes the following values of bit rates: {300, 305, 310, 315, 320, 325, 330, 335}, and the unit of the bit rate can be Mbps.

[0222] As an example, correspondingly, the network device can determine the rate table of Table 2 as described above, and when indicating the recommended rate, the network device can indicate indexes 0 to 7 to correspond to rates 300 Mbps to 335 Mbps.

[0223] As a second possible implementation, the fourth information indicating one or more bit rates includes that the fourth information indicates a minimum value and a maximum value of one or more bit rates, and the minimum value and the maximum value are used to determine the one or more bit rates. For example, the fourth information indicates that the minimum value of the one or more bit rates is 300 Mbps and the maximum value is 335 Mbps. Correspondingly, the recommended data sending rate determined by the network device can be greater than or equal to 300 Mbps and less than or equal to 335 Mbps.

[0224] In the embodiments of the present application, the network device can indicate one or more bit rates only by the maximum value and the minimum value, thereby reducing signaling overhead.

[0225] As an example, the minimum value and the maximum value are used to determine the one or more bit rates, including that the one or more bit rates are N bit rates between the minimum value and the maximum value, and N is a positive integer.

[0226] For example, N is equal to 8, and assuming that the rate range is divided into 8 bins, the network device can also determine the rate table as shown in Table 2.

[0227] Optionally, the value of N can be predefined, or in other words, the number of gears of the rate range division can be predefined. For example, if the network device uses 3 bits to indicate the recommended rate, up to 8 gears, or in other words, up to 8 gears of the rate range division, can be indicated.

[0228] It should be noted that the above examples are mainly described in a linear manner to divide the gears, and the gear division can also be in a non-linear manner, for example, the gears can be divided according to an exponential distribution, and the embodiments of the present application do not limit this.

[0229] In a possible implementation, the fourth information indicates a minimum value and a maximum value in the one or more bit rates, including: the fourth information includes the values of the minimum value and the maximum value, or in other words, the fourth information directly indicates the values of the minimum value and the maximum value, or in other words, the network device directly configures the values of the minimum value and the maximum value.

[0230] For example, the fourth information can include the following bit rate values: {300, 335}, which can be in Mbps, indicating that the minimum value in the one or more bit rates is 300 Mbps and the maximum value is 335 Mbps.

[0231] In another possible implementation, the fourth information indicates the minimum value and the maximum value in the one or more bit rates, including: the fourth information includes an index of the minimum value and an index of the maximum value, and the index of the minimum value and the index of the maximum value are respectively associated with the value of the minimum value and the value of the maximum value.

[0232] For example, the fourth information can include the following indexes: {35, 56}, and the two indexes can be associated with the value of the minimum value of 1 Mbps and the value of the maximum value of 8 Mbps through the table 1 described above.

[0233] In yet another possible implementation, the fourth information includes a second index, and the fourth information indicates the minimum value and the maximum value in the one or more bit rates, including: the fourth information indicates a third index and a fourth index associated with the minimum value and the maximum value, and the third index and / or the fourth index are determined according to the second index and a first parameter, and the first parameter is configured or predefined. For ease of description, hereinafter, the first parameter used to determine the third index and / or the fourth index is denoted as parameter #1.

[0234] As an example, the fourth information includes the second index, which can also be understood as the network device can only configure one index to indicate the rate range.

[0235] As a possible implementation, the third index and the fourth index are determined according to the second index and the parameter #1, including: the third index is the second index minus the parameter #1, and the fourth index is the second index plus the parameter #1.

[0236] As an example, the second index can be represented as index A, and the fourth information includes that the second index can represent a rate range from index (A-L) to index (A+L), where L can represent a value of the parameter #1.

[0237] For example, A=48, L=1, the second index can be represented as index 48, the third index can be represented as index 47, and the fourth index can be represented as index 49. The second index to the fourth index can be associated with a bit rate through the table 1 described above, and thus the rate range indicated by the second index A=48 can be 3.5 Mbps to 4.5 Mbps.

[0238] As another possible implementation, the third index and the fourth index are determined according to the second index and the parameter #1, and include: the third index is the second index minus the parameter #1, and the fourth index is the second index.

[0239] As an example, the second index can be represented as index A, and the fourth information includes that the second index can represent a rate range from index (A-L) to index (A+L), where L can represent a value of the parameter #1.

[0240] For example, A=48, L=1, the second index can be represented as index 48, the third index can be represented as index 47, and the fourth index can be represented as index 48. The second index to the fourth index can be associated with a bit rate through the table 1 described above, and thus the rate range indicated by the second index A=48 can be 3.5 Mbps to 4 Mbps.

[0241] As another possible implementation, the third index and the fourth index are determined according to the second index and the parameter #1, and include: the third index is the second index, and the fourth index is the second index plus the parameter #1.

[0242] As an example, the second index can be represented as index A, and the fourth information includes that the second index can represent a rate range from index (A-L) to index (A+L), where L can represent a value of the parameter #1.

[0243] For example, A=48, L=1, the second index can be represented as index 48, the third index can be represented as index 48, and the fourth index can be represented as index 49. The second index to the fourth index can be associated with a bit rate through the table 1 described above, and thus the rate range indicated by the second index A=48 can be 4 Mbps to 4.5 Mbps.

[0244] In the embodiments of the present application, the network device can indicate the minimum value and the maximum value in the one or more bit rates by only one index, and then indicate the recommended rate range. Based on this, the signaling overhead for indicating the recommended rate range can be further reduced.

[0245] Optionally, the parameter #1 can be predefined or configured by the network device.

[0246] As a possible implementation manner, the rate range is further determined according to a rate multiplier.

[0247] Optionally, the rate multiplier can be pre-configured by the network device, or the rate multiplier can be configured together with the recommended range by the network device to the terminal device.

[0248] For example, when the rate range is configured by using the index of Table 1 described above, the rate multiplier can be combined, for example, the network device configures the index 50 of Table 1 to indicate the rate range, and indicates that the rate multiplier 40 is used. Assuming that L=1, according to the possible implementation manner described above, the rate range indicated by the index 50 can be 200-220 Mbps or 180-200 Mbps or 180-220 Mbps.

[0249] S820, the network device sends the fifth information. Correspondingly, the terminal device receives the fifth information. The fifth information indicates the third bit rate, the third bit rate belongs to the one or more bit rates, and the third bit rate is the recommended data sending rate.

[0250] As an example, the fifth information can be carried in the MAC CE, and the third bit rate is indicated by the recommended rate field in the MAC CE.

[0251] As an example, the third bit rate belongs to the one or more bit rates, which can be understood as that the network device configures the rate range, and then indicates the third bit rate in the rate range.

[0252] For example, the rate range configured by the network device is shown in Table 2 described above, and the network device accurately indicates the third bit rate by indicating the index 0 to 7 to the terminal device.

[0253] In the embodiments of the present application, the network device can configure a dedicated rate range for the terminal device by the fourth information, and indicate the third bit rate as the recommended data sending rate by the fifth information based on the dedicated rate range. Based on this, by configuring the rate range by the network device, the recommended rate indicated by the network device can be more specific and accurate, and then the terminal device can effectively perform rate adjustment.

[0254] It should be noted that the foregoing determination of the rate table shown in Table 2 can be considered as an internal implementation operation of the network device and the terminal device, and in fact, the determined rate table does not necessarily need to be displayed. The network device and the terminal device can only determine the third bit rate based on the logic described in the embodiments of the present application.

[0255] Optionally, after S810, the method 800 can further include: the terminal device sends information #B, and correspondingly, the network device receives the information #B. The information #B is used to indicate the expected rate of the terminal device, and the expected rate belongs to the rate range configured by the network device.

[0256] It should be noted that the mode 1 and the mode 2 described above can be combined. For example, the terminal device can report the optional rate range #A, the network device can determine the final rate range #B based on the rate range #A reported by the terminal device, in combination with its own implementation, and configure the rate range #B to the terminal device. The possible implementation manner can be referred to the description in the mode 1 and the mode 2, and the embodiments of the present application will not be described herein.

[0257] Referring to FIG. 9, as an example, FIG. 9 is a schematic diagram of a communication method 900 provided by an embodiment of the present application. The method 900 shown in FIG. 9 can include the following steps.

[0258] Optionally, S910, the network device sends information #C, and correspondingly, the terminal device receives the information #C. The information #C indicates whether to use a new rate table.

[0259] As an example, the new rate table can be a rate table defined for a new service type, which can include an XR service, etc.

[0260] For example, considering the possible maximum rate and minimum rate of the XR service, the upper and lower boundaries of the new rate table can be determined. For example, the rate of the mainstream XR service can be in the range of 10 Mbps to 60 Mbps, and Table 3 is a possible design of the new rate table. Table 3 is similar to Table 1 described above, and can include 64 gears. The new air interface recommended bit rate value corresponding to index 0 in Table 3 is empty, which can be used to indicate that no new bit rate suggestion is given.

[0261] It should be understood that the 64 gears in Table 3 are only used as an example, and the number of gears included in the new table is not limited in the embodiments of the present application.

[0262] Table 3

[0263] It should also be understood that the recommended bit rates in Table 3 are evenly divided into 63 gears from 10 Mbps to 60 Mbps, and embodiments of the present application do not limit the specific division method. The gear division can also be in a non-linear manner, for example, the gears can be divided according to an exponential distribution, and embodiments of the present application do not limit this.

[0264] It should also be understood that Table 3 is only used to illustrate one possible new rate table, and embodiments of the present application do not limit the specific values in the new rate table. For example, Table 3 can also be a table with a minimum value of 0.25 Mbps and a maximum value of 1.5 Mbps, and the effect of indicating a 10-60 Mbps rate range can also be achieved by using a rate multiplier of 40.

[0265] S920, the network device sends information #D. Correspondingly, the terminal device receives the information #D. Wherein, the information #D indicates the recommended data sending rate.

[0266] As a possible implementation, the network device can indicate the information #D and the information #C in the same indication information.

[0267] Referring to FIG. 10, as an example, FIG. 10 is another MAC CE format provided by embodiments of the present application.

[0268] As an example, FIG. 10 can be based on FIG. 5, using 1 bit of reserved bits, denoted as T field, to indicate whether a new rate table is used.

[0269] For example, when T takes a value of 0, it means that the new table is not used, i.e., the rate table Table 1 is used, and when T takes a value of 1, it means that the newly defined rate table is used. Alternatively, when T takes a value of 1, it means that the new table is not used, i.e., the rate table Table 1 is still used, and when T takes a value of 0, it means that the newly defined rate table is used.

[0270] As another possible implementation, the network device can indicate the information #D and the information #C in different indication information respectively.

[0271] For example, the network device can first inform the terminal device to use a new rate table through an RRC message, and then use, for example, the MAC CE shown in FIG. 5 to indicate the recommended rate, but the terminal device understands that the recommended rate should be determined by referring to the newly defined table.

[0272] It should be noted that correspondingly, the terminal device can also use a method similar to the possible implementation described above to indicate to the network device to use the newly defined rate table to determine the expected rate of the terminal device, and the specific steps can be referred to the foregoing, and embodiments of the present application will not be described here.

[0273] In the embodiments of the present application, the protocol can redefine a new rate table for new services such as XR, so as to more match the actual rate range of the service when indicating the recommended rate, the network device is more specific and accurate when indicating the recommended rate, and the terminal device can effectively adjust the rate.

[0274] Referring to FIG. 11, as an example, FIG. 11 is a schematic diagram of a communication method 1100 provided by the embodiments of the present application. The method 1100 shown in FIG. 11 can include the following steps.

[0275] S1110, the network device sends the sixth information. Correspondingly, the terminal device receives the sixth information. Wherein, the sixth information indicates the fourth bit rate and the fifth bit rate.

[0276] As an example, the sixth information indicates the fourth bit rate and the fifth bit rate, which can also be understood as that the network device indicates multiple bit rates, and the multiple bit rates can be combined to more accurately indicate the recommended bit rate.

[0277] As an example, when indicating the recommended rate, the network device can indicate multiple rates at the same time, and determine the actual recommended rate by combining the multiple rates in the form of addition / subtraction, etc. For example, the network device can indicate multiple indexes in Table 1 described above in the MAC CE, so as to combine the actual recommended data transmission rate.

[0278] S1120, the terminal device determines the recommended data transmission rate based on the fourth bit rate and the fifth bit rate.

[0279] As an example, the fourth bit rate and the fifth bit rate can also be understood as multiple bit rates, and S1120 can also be understood as that the terminal device determines the recommended data transmission rate based on the multiple bit rates.

[0280] In the embodiments of the present application, the network device can indicate multiple bit rates to the terminal device through the sixth information, and the terminal device can more flexibly and accurately obtain the indication of the recommended rate based on the combination of the multiple bit rates.

[0281] As a possible implementation manner, the recommended data transmission rate in S1120 is the sum or difference of the fourth bit rate and the fifth bit rate. For example, the fourth bit rate is 8 Mbps, and the fifth bit rate is 2 Mbps, and then the recommended data transmission rate can be 10 Mbps or 6 Mbps.

[0282] As a possible implementation manner, the method 1100 can further include that the network device sends the seventh information. Correspondingly, the terminal device receives the seventh information. Wherein, the seventh information indicates that the recommended data transmission rate is further determined based on a third value, and the third value is configured.

[0283] As an example, the third value can be a configured or predefined value, and the third value can be used to determine the recommended data transmission rate together with the fourth bit rate and the fifth bit rate. The third value can also be referred to as a third parameter or a third multiplier or a semi-static rate multiplier, and the naming does not limit the protection scope of the embodiments of the present application.

[0284] Specifically, when the network device indicates a plurality of bit rates, each bit rate can be combined with the third value first, and then combined with other rates.

[0285] In the embodiments of the present application, the network device can indicate the terminal device that the recommended data transmission rate is determined based on the third value through the seventh information, that is, the terminal device can determine the recommended data transmission rate by combining the fourth bit rate, the fifth bit rate and the pre-configured third value, thereby further improving the flexibility of indicating the recommended rate.

[0286] As a possible implementation manner, the recommended data transmission rate is determined based on the third value, including that the recommended data transmission rate satisfies:

[0287] S3=S4×n3+S5; or,

[0288] S3=S4+S5×n3; or, S3=S4×n3+S5×n3;

[0289] Wherein, S3 represents the recommended data transmission rate, S4 represents the fourth bit rate, S5 represents the fifth bit rate, and n3 represents the third value.

[0290] Referring to FIG. 12, as an example, FIG. 12 is another MAC CE format provided by the embodiments of the present application. As shown in FIG. 12, the fourth bit rate and the fifth bit rate can be indicated by the index in Table 1, and X can represent whether the multiplier is used for the fourth bit rate.

[0291] It should be understood that the fourth bit rate field and the fifth bit rate field in FIG. 12 are used to indicate the values of the fourth bit rate and the fifth bit rate, and the embodiments of the present application do not limit the field names.

[0292] For example, the fourth bit rate field indicates that the fourth bit rate is 8 Mbps, X indicates that the multiplier 40 is used, and the fifth bit rate field indicates that the rate is 8 Mbps. Then the sixth information actually indicates that the recommended rate can be 8*40+8=328 Mbps, which is more accurate than indicating the recommended rate by using an index alone.

[0293] Referring to FIG. 13, as an example, FIG. 13 is another MAC CE format provided by the embodiments of the present application. As shown in FIG. 13, the fourth bit rate and the fifth bit rate can be indicated by the indexes in Table 1, X1 can represent whether the fourth bit rate uses a multiplier, and X2 can represent whether the fifth bit rate uses a multiplier.
