[0036] Embodiments of the present disclosure provide an information processing method, a communication device, a communication system, a storage medium, and a program product.

[0037] In a first aspect, an embodiment of the present disclosure provides an information processing method, wherein the method is executed by a network device, and the method includes: sending a first media access control MAC control unit CE to a terminal; wherein the first MAC CE includes first information, and the first information is used to indicate a first bit rate recommended by the network device, and the first MAC CE is a MAC CE of a first format, and a value range of the recommended bit rate indicated by the MAC CE of the first format is greater than a value range of the recommended bit rate indicated by the MAC CE of the second format.

[0038] In the above embodiment, the network device sends a first MAC CE to the terminal to indicate the first bit rate recommended by the network device to the terminal through the first MAC CE. Since the first MAC CE is a MAC CE of the first format, compared with the MAC CE of the second format, the recommended bit rate that can be indicated by the network device through the MAC CE of the first format has a wider range of values, thereby being able to meet the high rate requirements of specific types of services (such as XR services) of the terminal, so as to facilitate the terminal to adjust the rate of specific types of services to reduce the degree of network congestion.

[0039] In combination with some embodiments of the first aspect, in some embodiments, a first set of MAC CE associations in a first format is used to determine a value of a first bit rate; the first set includes multiple bit rate values ​​and indexes corresponding to the multiple bit rate values.

[0040] In the above embodiment, a new first set is introduced for the MAC CE of the first format, and the value of the first bit rate indicated by the MAC CE of the first format can be determined by the first set. The first set includes multiple bit rate values ​​and indexes corresponding to the multiple bit rate values. When the first MAC CE is a MAC CE of the first format, the bit rate value corresponding to the index indicated by the first MAC CE can be determined through the correspondence between the index and the bit rate value described in the first set, thereby obtaining the first bit rate indicated by the first MAC CE.

[0041] In combination with some embodiments of the first aspect, in some embodiments, the MAC CE of the first format includes: at least one first bit, the first bit being a reserved bit in the MAC CE of the first format; wherein the at least one first bit is used to indicate indexes corresponding to multiple bit rate values.

[0042] In the above embodiment, at least one reserved bit (i.e., the first bit) in the MAC CE of the first format can be extended as an indication bit indicating the index corresponding to multiple bit rate values, so as to increase the number of indication bits of the bit rate domain in the MAC CE of the first format, so as to increase the value range of the recommended bit rate indicated by the MAC CE of the first format.

[0043] In combination with some embodiments of the first aspect, in some embodiments, a MAC CE of the first format is associated with a first multiplication factor; the first multiplication factor is used to determine the first bit rate.

[0044] In the above embodiment, a new multiplication factor (i.e., the first multiplication factor) is introduced for the MAC CE of the first format. When the first MAC CE is a MAC CE of the first format, the first bit rate can be determined by the first multiplication factor and the bit rate value corresponding to the index indicated by the first MAC CE; thereby, the first multiplication factor is used to further expand the value range of the first bit rate indicated by the first MAC CE.

[0045] In combination with some embodiments of the first aspect, in some embodiments, the method also includes: sending second information to the terminal, the second information including at least one of the following: first indication information, used to indicate the terminal to determine the value of the first bit rate through the first set or the second set; wherein the second set is different from the first set; second indication information, used to indicate the terminal to use the first multiplication factor or the second multiplication factor; wherein the first multiplication factor is different from the second multiplication factor.

[0046] In the above embodiment, for the MAC CE of the first format, the correspondence between the index indicated by the MAC CE of the first format and the bit rate value can be the correspondence described by the first set or the correspondence described by the second set; in this case, the network device can send the first indication information to the terminal so that the network device and the terminal can reach a consistent understanding on whether the value of the first bit rate indicated by the first MAC CE is determined by the first set or the second set. Similarly, the network device can send the second indication information to the terminal so that the network device and the terminal can reach a consistent understanding on whether the multiplication factor of the first MAC CE is the first multiplication factor or the second multiplication factor. In this way, the first MAC CE sent by the network device can be correctly decoded by the terminal.

[0047] In combination with some embodiments of the first aspect, in some embodiments, the MAC CE of the first format includes: a second bit, the second bit is a reserved bit in the MAC CE of the first format; the second bit is used to indicate at least one of the following: the terminal determines the value of the first bit rate through the first set or the second set; the second set is different from the first set; the terminal uses the first multiplication factor or the second multiplication factor; the first multiplication factor is different from the second multiplication factor.

[0048] In the above embodiment, at least one reserved bit (i.e., the second bit) in the MAC CE of the first format can be extended as an indication bit to indicate whether the value of the first bit rate indicated by the first MAC CE is determined by the first set or the second set, and / or, to indicate whether the multiplication factor of the first MAC CE uses the first multiplication factor or the second multiplication factor. In the embodiment of the present disclosure, the reserved bit of the MAC CE of the first format is used to indicate the above information without the need for the network device to send additional indication information to the terminal, so that the network device and the terminal reach a consistent understanding of the above information, so that the first MAC CE sent by the network device can be correctly decoded by the terminal.

[0049] In combination with some embodiments of the first aspect, in some embodiments, the method also includes: sending third information to the terminal, the third information is used to indicate whether the terminal uses an extended buffer status report (Buffer Status Reports, BSR) table for BSR reporting, and the third information is also used to indicate at least one of the following: the terminal uses the first set or the second set to determine the value of the first bit rate; the second set is different from the first set; the terminal uses the first product parameter or the second product parameter; the first product factor is different from the second product factor.

[0050] In the above embodiment, the network device can reuse the existing indication information (i.e., the third information) to implicitly indicate whether the terminal uses which set to determine the value of the first bit rate, and which multiplication factor the terminal uses, thereby reducing signaling overhead. Since the value range of the buffer size indicated by the extended BSR table is larger, if the third information indicates that the terminal uses the extended BSR table to report the BSR, it means that the data rate of the logical channel is relatively large. In this case, in order to meet the high rate requirements of the logical channel, the value of the first bit rate indicated by the first MAC CE should be determined by the first set, and / or the multiplication factor of the first MAC CE should be the first multiplication factor, so as to expand the value range of the first bit rate that the first MAC CE can indicate.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the first bit rate is any one of the following: a bit rate for each logical channel (Logic Channel, LCH); a bit rate for each data radio bearer (Data Radio Bearer, DRB); a bit rate for each quality of service (Quality of Service, QoS) flow.

[0052] In the above embodiment, the first bit rate indicated by the first MAC CE may be of LCH granularity, or of DRB granularity, or of QoS flow granularity, so that the terminal can implement rate adjustment of different granularities when performing rate adjustment.

[0053] In combination with some embodiments of the first aspect, in some embodiments, the MAC CE of the first format includes multiple first identifiers and first bit rates corresponding to the multiple first identifiers; wherein the first identifier is used to indicate one of the LCH, DRB and Qos flows.

[0054] In the above embodiment, the MAC CE of the first format may include multiple first identifiers and first bit rates corresponding to the multiple first identifiers, thereby using one MAC CE to simultaneously indicate multiple first bit rates, thereby improving the efficiency of the network device in recommending bit rates to the terminal.

[0055] In combination with some embodiments of the first aspect, in some embodiments, a MAC CE of the first format includes: multiple information field pairs; wherein each information field pair includes: a first information field and a second information field; the first information field is used to indicate a first identifier; and the second information field is used to indicate a first bit rate corresponding to the first identifier.

[0056] In the above embodiment, the MAC CE of the first format may include multiple information field pairs, each of which includes a first information field and a second information field, so as to indicate the first identifier through the first information field and indicate the first bit rate corresponding to the first identifier through the second information field, thereby realizing the simultaneous indication of multiple first bit rates. The embodiment of the present disclosure provides a format of a MAC CE that can simultaneously indicate multiple first bit rates, and the implementation is simple.

[0057] In combination with some embodiments of the first aspect, in some embodiments, the first MAC CE includes: a second identifier, where the second identifier is used to indicate the format of the first MAC CE.

[0058] In the above embodiment, the first MAC CE may include a second identifier to indicate the format of the first MAC CE through the second identifier, so that after receiving the first MAC CE, the terminal can determine the format of the first MAC CE based on the second identifier, thereby determining which set to use and / or which multiplication factor to use to determine the first bit rate indicated by the first MAC CE.

[0059] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0060] A second MAC CE sent by a receiving terminal is received, where the second MAC CE is a MAC CE in a first format, and the second MAC CE carries fourth information, where the fourth information is used to indicate a first bit rate requested by the terminal.

[0062] In combination with some embodiments of the first aspect, in some embodiments, the method also includes: sending fifth information to the terminal, the fifth information is used to configure the first timer; wherein the first timer is used to prohibit the terminal from sending a second MAC CE during the operation of the first timer.

[0063] In the above embodiment, the network device can send the fifth information to the terminal to configure the first timer for the terminal through the fifth information, so that the terminal stops sending the second MAC CE to the network device during the operation of the first timer, thereby reducing the situation where the terminal frequently sends the second MAC CE and reducing the waste of communication resources.

[0064] In combination with some embodiments of the first aspect, in some embodiments, the first timer includes at least one of the following: a second timer, the second timer is configured for each LCH; a third timer, the third timer is configured for each DRB; a fourth timer, the fourth timer is configured for each Qos flow.

[0065] In the above embodiment, the first timer configured by the network device can be of LCH granularity, DRB granularity and / or Qos flow granularity, so that first timers of different granularities can be configured for the terminal according to different granularities of the first bit rate requested by the terminal. When the terminal requests first bit rates of different granularities through the second MAC CE, different restrictions are imposed on the sending frequency of requests for first bit rates of different granularities.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0067] The sixth information sent by the receiving terminal is used to indicate whether the terminal supports the MAC CE in the first format.

[0068] In the above embodiment, the network device can receive the sixth information sent by the terminal to determine whether the terminal supports the first format of MAC CE based on the sixth information, so that the network device can determine which format of MAC CE to send to the terminal, thereby reducing the situation where the MAC CE in the first format sent by the network device cannot be decoded by the terminal because the terminal does not support the MAC CE in this format.

The statement of the description object refers to the description in the context of the claims or embodiments, and should not constitute unnecessary restrictions due to the use of prefixes. For example, if the description object is a "field", the ordinal number before the "field" in the "first field" and the "second field" does not limit the position or order between the "fields", and the "first" and "second" do not limit whether the "fields" they modify are in the same message, nor do they limit the order of the "first field" and the "second field". For another example, if the description object is a "level", the ordinal number before the "level" in the "first level" and the "second level" does not limit the priority between the "levels". For another example, the number of description objects is not limited by the ordinal number, and can be one or more. Taking the "first device" as an example, the number of "devices" can be one or more. In addition, the objects modified by different prefixes may be the same or different. For example, if the description object is "device", then the "first device" and the "second device" may be the same device or different devices, and their types may be the same or different. For another example, if the description object is "information", then the "first information" and the "second information" may be the same information or different information, and their contents may be the same or different.

[0122] In some embodiments, the access network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be referred to as a control unit (control unit). The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

[0123] In some embodiments, the core network device may be a device including a first network element, etc., or may be a plurality of devices or a group of devices, each including a first network element.

[0130] In some embodiments, the terminal sends a request to the base station for a recommended bit rate. Figure 1B As shown, Figure 1BThe present invention is a schematic diagram of an interaction between a terminal and a network device for bit rate recommendation according to an exemplary embodiment. The terminal sends a MAC CE to a base station, and the MAC CE includes a recommended bit rate query message. The terminal receives a MAC CE carrying a recommended bit rate from the base station, so that the terminal can adjust the codec bit rate when the network is congested.

[0131] In some embodiments, Figure 1C As shown, Figure 1C The MAC CE format diagram according to an exemplary embodiment is shown in FIG. The MAC CE may include: an LCID field, an uplink (UL) / downlink (DL) field, a bit rate (Bit Rate) field, an X field, and an R field.

[0132] In some embodiments, the LCID field is used to indicate the identifier of a logical channel to which the recommended bit rate information or the recommended bit rate query information is applicable; the length of the LCID field is 6 bits.

[0133] In some embodiments, the UL / DL domain is used to indicate whether the recommended bit rate information or the recommended bit rate query information is applicable to the uplink or the downlink. The length of the UL / DL domain is 1 bit. A bit value of 0 in the UL / DL domain may indicate that the recommended bit rate information or the recommended bit rate query information is applicable to the downlink, and a bit value of 1 in the UL / DL domain may indicate that the recommended bit rate information or the recommended bit rate query information is applicable to the uplink.

[0134] In some embodiments, the bit rate field may indicate recommended bit rate information or recommended bit rate query information. The length of the bit rate field is 6 bits. In one embodiment, when the MAC CE includes recommended bit rate information, the bit rate field is used to indicate the recommended bit rate value. In one embodiment, when the MAC CE includes recommended bit rate query information, the bit rate field is used to indicate the recommended bit rate value requested by the terminal. In one embodiment, the recommended bit rate value may come from a bit rate value set associated with the MAC CE (such as a second set), as shown in Table 1 below, wherein the bit rate value set includes 56 bit rate values. In one embodiment, each bit rate value in the bit rate value set is associated with an index. Based on this, the recommended bit rate value may be indicated by the index contained in the bit rate field.

[0135] In some embodiments, the X field, i.e., the bit rate multiplier field, for a terminal supporting the recommended bit rate multiplier parameter, when the logical channel indicated by the LCID field is configured with the bit rate product parameter, the bit value of the X field is 1, used to indicate that the actual value of the recommended bit rate is the recommended bit rate value corresponding to the index indicated by the bit rate field multiplied by the bit rate multiplier parameter; the bit value of the X field is 0, used to indicate that the actual value of the recommended bit rate is the recommended bit rate value corresponding to the index indicated by the bit rate field.

[0136] In some embodiments, the R field, ie, the reserved field, has its bit value set to 0.

[0137]

[0138] Table 1

[0139] In some embodiments, it is necessary to consider using the MAC CE as a congestion indication information to facilitate the terminal to adjust the rate. However, the MAC CE in the above format (hereinafter referred to as the MAC CE in the second format) can only indicate the bit rate values ​​corresponding to 56 indexes, and the range of the bit rate values ​​is small. For some specific types of services, such as XR services, since the rate of XR services is higher, the range of the bit rate values ​​indicated by the MAC CE in the second format cannot meet the rate requirements of the XR services, so optimization is required.

[0140] In order to solve the above problems, the embodiments of the present disclosure provide an information processing method, a communication device, a communication system, a storage medium and a program product to enhance the MAC CE, thereby meeting the rate requirements of the XR service and improving the reliability of the system.

[0141] Figure 2A FIG. 1 is an interactive schematic diagram of an information processing method according to an exemplary embodiment. Figure 2A As shown, the embodiment of the present disclosure relates to an information processing method, which is used in a communication system 100, and the method includes:

[0142] Step S2101: The network device sends a first MAC CE to the terminal.

[0143] In some embodiments, the terminal receives a first MAC CE sent by a network device.

[0144] In some embodiments, the first MAC CE may be a MAC CE in a first format. In one embodiment, the MAC CE in the first format may be a MAC CE in an enhanced format, which is used for rate adjustment of XR services.

[0145] In some embodiments, the range of values ​​of the recommended bit rate indicated by the MAC CE in the first format is greater than the range of values ​​of the recommended bit rate indicated by the MAC CE in the second format. In one embodiment, for a first type of service with a higher data rate requirement, such as an XR service, the MAC CE in the first format can be used as congestion indication information to facilitate the terminal to adjust the rate of the first type of service. Compared with the range of values ​​of the recommended bit rate indicated by the MAC CE in the second format, the range of values ​​of the recommended bit rate indicated by the MAC CE in the first format can meet the high rate requirements of the first type of service (such as the XR service) and improve the reliability of the system.

[0146] In some embodiments, the terminal or the network device may select one or more recommended bit rate values ​​from the first set as the recommended bit rate value indicated by the MAC CE in the first format.

[0147] In some embodiments, the MAC CE of the first format is different from the MAC CE of the second format. In one embodiment, the value range of the recommended bit rate indicated by the MAC CE of the first format is greater than the value range of the recommended bit rate indicated by the MAC CE of the second format.

[0148] In one embodiment, a MAC CE of a first format is associated with a first set, and the first set may include multiple bit rate values. A value range (i.e., the value range of multiple bit rates in the first set) can be determined based on the maximum and minimum values ​​of these bit rate values. The second set associated with the second MAC CE is different. The second set may include multiple bit rate values. A value range (i.e., the value range of multiple bit rates in the second set) can be determined based on the maximum and minimum values ​​of these bit rate values. The maximum value of the multiple bit rate values ​​in the first set is greater than the maximum value of the multiple bit rate values ​​in the second set. In this way, the value range of the recommended bit rate indicated by the MAC CE of the first format is greater than the value range of the recommended bit rate indicated by the MAC CE of the second format. In an example, the first set may include 8 bit rate values, such as {25, 29, 32, 36, 40, 48, 56, 72}, in which case the value range of the multiple bit rate values ​​in the first set may be [25, 72]. The second set may include 8 bit rate values, such as {0,9,11,13,17,21,25,29}. In this case, the value range of the multiple bit rate values ​​in the second set may be [0,29]. In this case, 72>29, and the value range of the recommended bit rate indicated by the MAC CE of the first format is greater than the value range of the recommended bit rate indicated by the MAC CE of the second format. In an example, the first set may include 8 bit rate values, such as {25,29,32,36,40,48,56,72}. In this case, the value range of the multiple bit rate values ​​in the first set may be [25,72]. The second set may include 8 bit rate values, such as {0,9,11,13,17,21,25,29}. In this case, the value range of the multiple bit rate values ​​in the second set may be [0,29]. At this time, 72>29, the value range of the recommended bit rate indicated by the MAC CE in the first format is greater than the value range of the recommended bit rate indicated by the MAC CE in the second format.

[0149] In some embodiments, the number of the plurality of bit rates in the first set may be greater than the number of the plurality of bit rates in the second set. In some embodiments, the number of the plurality of bit rates in the first set may be equal to the number of the plurality of bit rates in the second set.

[0150] In some embodiments, the presentation form of the first set is not specifically limited, as long as it can be used to indicate the correspondence between the bit rate value and the index. For example, the first set can be in the form of a table, and the table is also used to indicate the correspondence between the index and the bit rate value.

[0151] In one embodiment, the correspondence between the index indicated by the first set and the bit rate value is different from the correspondence between the index indicated by the second set and the bit rate value.

[0152] In some embodiments, the bit rate value corresponding to the same index in the first set is greater than the bit rate value corresponding to the same index in the second set. It should be noted that the bit rate value corresponding to the same index in the first set is greater than that in the second set. In this case, although the number of indexes included in the first set is the same as the number of indexes included in the second set, the range of bit rates that can be indicated by the first set is greater than the range of bit rates that can be indicated by the second set.

[0153] In some embodiments, the number of indexes included in the first set is greater than the number of indexes included in the second set. It should be noted that, in this case, the bit rate value corresponding to the same index in the first set is the same as the bit rate value corresponding to the same index in the second set, but because the number of indexes included in the first set is greater than the number of indexes included in the second set, the value range of the bit rate value that can be indicated by the first set is greater than the value range of the bit rate value that can be indicated by the second set.

[0154] In one example, the second set includes 56 bit rate values, as shown in the above Table 1. The first set includes more than 56 bit rate values.

[0155] In some embodiments, the first set may be configured by the network device to the terminal; or, the first set may be pre-defined in the network device and the terminal by protocol agreement or the like.

[0156] In some embodiments, the MAC CE of the first format includes at least one first bit, and the first bit is a reserved bit in the MAC CE of the first format. Among them, the at least one first bit is used to indicate the index corresponding to multiple bit rate values. In some embodiments, the reserved bit in the MAC CE of the first format can be used to increase the number of indication bits of the bit rate field in the MAC CE of the first format, thereby increasing the value range of the recommended bit rate indicated by the MAC CE of the first format.

[0157] In one example, compared to the MAC CE of the second format that can indicate 56 bit rate values, the reserved bits in the MAC CE of the first format can be extended as indication bits of the bit rate field, so that the indication bits of the bit rate field in the MAC CE of the first format are increased. When the indication bits in the bit rate field of the MAC CE of the first format are 8 bits, the MAC CE of the first format can indicate 256 bit rate values.

[0158] In some embodiments, the value of the recommended bit rate indicated by the MAC CE in the first format may be determined according to the first set. It should be noted that the value of the recommended bit rate indicated by the MAC CE in the first format is determined by the first set. In this case, when the format of the MAC CE is determined, it is also determined by which set the value of the recommended bit rate indicated by the MAC CE is determined, and there is no need to additionally indicate through indication information whether the recommended bit rate is determined by the first set or the second set.

[0159] In some embodiments, the value of the recommended bit rate indicated by the MAC CE of the first format may be determined according to the first set or the second set. It should be noted that the value of the recommended bit rate indicated by the MAC CE of the first format may be determined by the first set or the second set. In this case, since the correspondence between the index indicated by the first set and the bit rate value is different from the correspondence between the index indicated by the second set and the bit rate value, the network device needs to reach a consistent understanding with the terminal in order to correctly decode the MAC CE of the first format and determine the value of the recommended bit rate indicated by the MAC CE of the first format.

[0160] In some embodiments, the network device may send first indication information to the terminal, and the first indication information is used to indicate that the terminal determines the value of the recommended bit rate indicated by the MAC CE in the first format through the first set or the second set. In some embodiments, when the value of the recommended bit rate indicated by the MAC CE in the first format can be determined by the first set or by the second set, the network device may send the first indication information to the terminal so that the terminal determines the value of the recommended bit rate indicated by the MAC CE in the first format through the first set or the second set according to the first indication information.

[0161] In some embodiments, the MAC CE of the first format is associated with a first multiplication factor.

[0162] In some embodiments, the first multiplication factor is used to determine the recommended bit rate indicated by the MAC CE of the first format. In one embodiment, the actual value of the recommended bit rate indicated by the MAC CE of the first format is determined based on the product between the bit rate value corresponding to the index and the first multiplication factor.

[0163] In some embodiments, the name of the first multiplication factor is not specifically limited, and may be, for example, a first multiplication parameter, a first multiplier, etc.

[0164] The first multiplication factor is different from the second multiplication factor.In some embodiments, the second multiplication factor is associated with a MAC CE of a second format.

[0165] In some embodiments, the value range of the first multiplication factor is different from the value range of the second multiplication factor.

[0166] In some embodiments, the value of the first multiplication factor is determined by a parameter value associated with a MAC CE of a first format, and the value of the second multiplication factor is determined by a parameter value associated with a MAC CE of a second format.

[0167] In some embodiments, a MAC CE of a first format is associated with multiple parameter values, and a MAC CE of a second format is associated with multiple parameter values; wherein the number of parameter values ​​associated with the MAC CE of the first format is greater than the number of parameter values ​​associated with the MAC CE of the second format. In some embodiments, compared with the parameter values ​​associated with the MAC CE of the second format, the number of parameter values ​​associated with the MAC CE of the first format is greater, so that the first multiplication factor has a larger value range.

[0168] In some embodiments, the third set of MAC CE associations in the first format includes multiple parameter values, and the fourth set of MAC CE associations in the second format includes multiple parameter values. The fourth set may be a subset of the third set. In some embodiments, the embodiments of the present disclosure may expand the value range of the existing multiplication factor (i.e., the second multiplication factor) to obtain a new value range, and use the value range as the value range of the first multiplication factor, thereby meeting the high rate requirement of the first type of service.

[0169] In an example, the fourth set may be {40, 70, 100, 200}; the third set may be {20, 30, 40, 70, 100, 150, 200}.

[0170] In some embodiments, multiple parameter values ​​associated with the MAC CE in the first format may be configured by the network device to the terminal; or, may be pre-defined in the network device and the terminal by protocol agreement or the like.

[0171] In some embodiments, the value of the recommended bit rate indicated by the MAC CE in the first format may be determined according to a fifth set, and the fifth set may include multiple bit rate values ​​and indexes corresponding to the multiple bit rate values.

[0172] In some embodiments, the correspondence between the index indicated by the fifth set and the bit rate value is determined based on the maximum bit rate value, the minimum bit rate value and the number of indexes.

[0173] In some embodiments, the maximum bit rate value may be the maximum value of the recommended bit rate that the network device can provide, or the maximum bit rate value may be the maximum value of the recommended bit rate requested by the terminal.

[0174] In some embodiments, the minimum bit rate value may be the minimum value of the recommended bit rate that the network device can provide, or the minimum bit rate value may be the minimum value of the recommended bit rate requested by the terminal.

[0175] In some embodiments, the number of indexes is determined according to the number of indicator bits used to indicate the index corresponding to the bit rate value in the MAC CE of the first format. For example, if 8 indicator bits in the MAC CE of the first format are used to indicate the index corresponding to the bit rate value, the number of indexes can be determined to be 256.

[0176] In some embodiments, the number of indexes may be determined by negotiation between the network device and the terminal. It should be noted that the network device and the terminal negotiate to determine the number of indexes of the fifth set, on this basis, the network device and the terminal also reach a consistent understanding of the number of indication bits for indicating the index corresponding to the bit rate value in the MACCE of the first format.

[0177] In some embodiments, the network device may determine multiple indexes in the fifth set and bit rate values ​​corresponding to the multiple indexes according to the maximum bit rate value, the minimum bit rate value, and the number of indexes.

[0178] In an example, the correspondence between each index in the fifth set and the bit rate value corresponding to the index can be determined according to expression (1):

[0179] Where p = (B max / B min ) 1 / (N-1) -1; (1)

[0180] Among them, B min is the minimum bit rate value, B max is the maximum bit rate value, N is the value from B min To B max The number of values ​​of the amount of data, is an upward value function, where k is an integer greater than or equal to 0, and k is less than or equal to N.

[0181] In some embodiments, the network device may send seventh information to the terminal, and the seventh information is used by the terminal to generate the fifth set; the seventh information may be used to indicate the maximum bit rate value, the minimum bit rate value, and the number of indexes required to generate the fifth set. It should be noted that after generating the fifth set, the network device may send the seventh information to the terminal so that the terminal generates the fifth set according to the seventh information, so that the network device and the terminal reach a consistent understanding of the multiple bit rate values ​​contained in the fifth set and the indexes corresponding to the multiple bit rate values.

[0182] In some embodiments, the terminal may send eighth information to the network device, and the eighth information is used by the network device to generate the fifth set; the eighth information may be used to indicate the maximum bit rate value, the minimum bit rate value, and the number of indexes required to generate the fifth set. It should be noted that after generating the fifth set, the terminal may send the eighth information to the network device so that the network device generates the fifth set according to the eighth information, so that the network device and the terminal reach a consistent understanding of the multiple bit rate values ​​contained in the fifth set and the indexes corresponding to the multiple bit rate values.

[0183] In some embodiments, the first multiplication factor is a third multiplication factor. In some embodiments, the third multiplication factor may be a new multiplication factor introduced by the embodiments of the present disclosure, and the third multiplication factor may be directly used as the first multiplication factor associated with the MAC CE of the first format.

[0184] In some embodiments, the first multiplication factor is the product of the third multiplication factor and the second multiplication factor. In some embodiments, the third multiplication factor may be a new multiplication factor introduced by the embodiments of the present disclosure, and the product of the existing multiplication factor (i.e., the second multiplication factor) and the third multiplication factor may be used as the first multiplication factor associated with the MAC CE of the first format. In this way, the value range of the first multiplication factor associated with the MAC CE of the first format is different from the value range of the second multiplication factor associated with the MAC CE of the second format.

[0185] In some embodiments, the third multiplication factor may be configured by the network device to the terminal; or, it may be predefined in the network device and the terminal by protocol agreement or the like.

[0186] In some embodiments, the recommended bit rate indicated by the MAC CE of the first format may be determined by the product of the first multiplication factor and the bit rate value indicated by the index. In this case, when the format of the MAC CE is determined, it is also determined which multiplication factor is used in the process of determining the actual value of the recommended bit rate indicated by the MAC CE, and there is no need to indicate it additionally through the indication information.

[0187] In some embodiments, the recommended bit rate indicated by the MAC CE of the first format may be determined by the product of a first multiplication factor and a bit rate value indicated by an index, or may be determined by the product of a second multiplication factor and a bit rate value indicated by an index. In this case, since the first multiplication factor and the second multiplication factor are different, the network device needs to reach a consistent understanding with the terminal regarding the multiplication factor used in the process of determining the actual value of the recommended bit rate indicated by the MAC CE of the first format, in order to correctly decode the MAC CE of the first format and determine the value of the recommended bit rate indicated by the MAC CE of the first format.

[0188] In some embodiments, the network device may send second indication information to the terminal, where the second indication information is used to instruct the terminal to use the first multiplication factor or the second multiplication factor.

[0189] In some embodiments, the recommended bit rate indicated by the MAC CE of the first format can be determined by the product of the first multiplication factor and the bit rate value indicated by the index, or can be determined by the product of the second multiplication factor and the bit rate value indicated by the index. In this case, the network device can send a second indication message to the terminal so that the terminal determines whether to use the first multiplication factor or the second multiplication factor based on the second indication information.

[0190] In some embodiments, a MAC CE of a first format includes: a second bit, the second bit is a reserved bit in the MAC CE of the first format, and the second bit is used to indicate at least one of the following: the terminal determines the value of the recommended bit rate indicated by the MAC CE of the first format through the first set or the second set; the terminal uses the first multiplication factor or the second multiplication factor. It should be noted that the reserved bit in the MAC CE of the first format can be extended as an indication bit to use different bit values ​​of the second bit to indicate that the terminal determines the value of the recommended bit rate indicated by the MAC CE of the first format through the first set or the second set. And / or, different bit values ​​of the second bit can be used to indicate that the terminal uses the first multiplication factor or the second multiplication factor, so that there is no need for the network device to send additional indication information to the terminal, thereby reducing information overhead.

[0191] In some embodiments, the reserved bits in the MAC CE of the first format may include: bits of the R field.

[0192] In some embodiments, the reserved bits in the MAC CE of the first format may also include: bits of the UL / DL domain. In some embodiments, the bits of the UL / DL domain in the MAC CE of the first format may be extended for other purposes. For example, the bits of the UL / DL domain in the MAC CE of the first format may be extended as an indication bit of an index corresponding to an indication bit rate value. In some embodiments, the reserved bits in the MAC CE of the first format may also include: bits of the X domain. In some embodiments, the bits of the X domain in the MAC CE of the first format may be extended for other purposes. For example, the bits of the X domain in the MAC CE of the first format may be extended as an indication bit of an index corresponding to an indication bit rate value. It should be noted that the X domain in the MAC CE of the first format may be cancelled, in other words, the X domain is no longer used to indicate whether the recommended bit rate indicated by the MAC CE of the first format is determined by a multiplication factor. In this case, the recommended bit rate indicated by the MAC CE of the first format is determined by the bit rate value corresponding to the index.

[0193] In one embodiment, the first bit in the MAC CE of the first format may include: a bit of the X field and a bit of the R field. As an example, the network device may extend the X field bit and one bit of the R field of the MAC CE of the first format as the first bit. In other words, the 6 bits of the bit rate field, one bit of the X field, and one bit of the R field in the MAC CE of the first format are used together to indicate the index of multiple bit rate values. It should be noted that the indication bit used to indicate the index in the MAC CE of the first format may be predefined in the network device and the terminal by a protocol agreement or the like. When the indication bit used to indicate the index in the MAC CE of the first format also includes a bit of the X field, it indicates that the X field in the MAC CE of the first format is cancelled, and the recommended bit rate indicated by the MAC CE of the first format is determined by the bit rate value corresponding to the index.

[0194] In some embodiments, the network device may send third information to the terminal, where the third information is used to indicate whether the terminal uses an extended BSR table to report the BSR.

[0195] In some embodiments, the third information is also used to instruct the terminal to determine the value of the recommended bit rate indicated by the MAC CE of the first format through the first set or the second set.

[0196] In some embodiments, the third information is further used to instruct the terminal to use the first multiplication factor or the second multiplication factor.

[0197] In some embodiments, the third information is indication information for indicating whether the terminal uses an extended BSR table. The network device can reuse the existing indication information to implicitly indicate which set the terminal uses to determine the value of the recommended bit rate indicated by the MACCE of the first format, and indicate the terminal to use the first multiplication factor or the second multiplication factor. It can be understood that since the value range of the amount of data indicated by the extended BSR table is larger, if the logical channel used by the terminal is configured to use the extended BSR table, it means that the data rate of the logical channel is relatively large. In this case, the value range of the recommended bit rate indicated by the MAC CE of the first format needs to meet the high rate requirements of the logical channel, so the value of the recommended bit rate indicated by the MAC CE of the first format can be determined by the first set, and the multiplication factor used in the determination process of the recommended bit rate indicated by the MAC CE of the first format can be the first multiplication factor. If the logical channel used by the terminal is not configured to use the extended BSR table, it means that the data rate of the logical channel is relatively small. In this case, the value of the recommended bit rate indicated by the MAC CE in the first format may be determined by the second set, and the multiplication factor used in the determination process of the recommended bit rate indicated by the MAC CE in the first format may be the second multiplication factor.

[0198] In some embodiments, a MAC CE of a first format may be used to indicate a recommended bit rate. It should be noted that, in the case where a MAC CE of a first format is used to indicate a recommended bit rate, the MAC CE of the first format maintains the size of the original MAC CE of the second format, but is different from the MAC CE of the second format in that the MAC CE of the first format extends at least part of the reserved bits to a new purpose. In one example, the reserved bit may be extended as a first bit, in other words, the reserved bit is used as an indication bit to indicate an index corresponding to a bit rate value. In one example, the reserved bit may be extended as a second bit, in other words, the reserved bit is used to indicate a value of the recommended bit rate determined according to the first table or the second table.

[0199] In some embodiments, a MAC CE of a first format may be used to indicate multiple recommended bit rates.

[0200] In some embodiments, the multiple recommended bit rates indicated by the MAC CE of the first format may be for multiple LCHs.

[0201] In some embodiments, the multiple recommended bit rates indicated by the MAC CE in the first format may be for multiple DRBs.

[0202] In some embodiments, the multiple recommended bit rates indicated by the MAC CE in the first format may be for multiple QoS flows.

[0203] In some embodiments, the MAC CE in the first format may include multiple recommended bit rates and first identifiers corresponding to the multiple recommended bit rates.

[0204] In some embodiments, the first identifier may be used to identify one of LCH, DRB and QoS flow. In one embodiment, the first identifier may be LCH identifier ID, DRB ID or QoS flow ID.

[0205] In some embodiments, the MAC CE of the first format includes: a plurality of information field pairs, each information field pair including a recommended bit rate corresponding to the first identifier.

[0206] In one example, if Figure 1D As shown, Figure 1D 1 is a schematic diagram of a MAC CE of a first format according to an exemplary embodiment. Each information field pair in the MAC CE of the first format may include: an LCID field, a UL / DL field, a bit rate field, an X field, and an R field. The format of each information field pair in the MAC CE of the first format may be the same as that of the MAC CE of the second format.

[0207] In some embodiments, a MAC CE of a first format may include N information fields, where N is a positive integer greater than or equal to 3. The N information fields include: a third information field and multiple fourth information fields. Among them, the third information field includes a bitmap, and multiple bits in the bitmap are associated with multiple first identifiers, and each first identifier is associated with a bit. Each fourth information field is used to indicate the recommended bit rate corresponding to each first identifier. It should be noted that in order to save the indication overhead of the first identifier in the MAC CE of the first format, multiple first identifiers can be indicated by a bitmap.

[0208] In some embodiments, each bit having a first bit value in the bitmap corresponds to a first identifier. It should be noted that the number of bits included in the bitmap is greater than or equal to the number of first identifiers.

[0209] In one example, each bit in the bitmap corresponds to an LCH. The bit corresponding to an LCH is a first bit value, which is used to indicate that a MAC CE of a first format includes a recommended bit rate corresponding to the LCH; and the bit corresponding to an LCH is a second bit value, which is used to indicate that a MAC CE of a first format does not include a recommended bit rate corresponding to the LCH.

[0210] In one example, if Figure 1E As shown, Figure 1E This is a schematic diagram 2 of a MACCE of a first format shown according to an exemplary embodiment. The MAC CE of the first format includes: a third information field and multiple fourth information fields. The multiple bits in the third information field correspond to LCH8 to LCH1 respectively. Each fourth information field may include a bit rate field, an X field, and an R field, and the bit rate field in each fourth information field is used to indicate the recommended bit rate corresponding to the bit with the first bit value in the third information field. For example, the values ​​of the multiple bits of the third information field are 00101000, the first fourth information field of the two fourth information fields is used to indicate the recommended bit rate corresponding to LCH6, and the second fourth information field is used to indicate the recommended bit rate corresponding to LCH4.

[0211] In some embodiments, each bit in the bitmap corresponds to a first identifier. It should be noted that the number of bits included in the bitmap depends on the number of first identifiers. In one embodiment, the bitmap is used to indicate the LCH corresponding to the recommended bit rate, rather than indicating all LCHs, thereby reducing the number of bits in the bitmap and reducing signaling overhead.

[0212] In some embodiments, in the case where the terminal supports a MAC CE in a first format, the first MAC CE may be a MAC CE in the first format.

[0213] In some embodiments, the first MAC CE may be a MAC CE in the second format. In some embodiments, when the terminal does not support the MAC CE in the first format, the first MAC CE sent by the network device may be a MAC CE in the second format.

[0214] In some embodiments, before the network device sends the first MAC CE to the terminal, the terminal may send sixth information to the network device, where the sixth information indicates whether the terminal supports the MAC CE in the first format. It should be noted that the terminal sends the sixth information to the network device so that the network device knows whether the terminal supports the MAC CE in the first format, so that the network device determines whether to send the MAC CE in the first format or the MAC CE in the second format to the terminal.

[0215] In some embodiments, the present disclosure does not specifically limit the name of the sixth information, and may be, for example, capability information, capability indication information, etc.

[0216] In some embodiments, the first MAC CE includes: a second identifier, the second identifier is used to indicate the format of the first MAC CE. In one embodiment, the second identifier can indicate that the first MAC CE is a MAC CE of the first format. In one embodiment, the second identifier can indicate that the first MAC CE is a MAC CE of the second format. Based on this, the terminal can determine whether the first MAC CE is a MAC CE of the first format or a MAC CE of the second format according to the second identifier.

[0217] In some embodiments, the format of the first MAC CE can be indicated by different values ​​of the second identifier. In one example, the second identifier is a first value (such as 1) to indicate that the first MAC CE is a MAC CE of the first format. The second identifier is a second value (such as 0) to indicate that the first MAC CE is a MAC CE of the second format.

[0218] In some embodiments, the format of the first MAC CE can be indicated by whether it contains a second identifier. In one example, the second identifier is used to indicate that the first MAC CE is a MAC CE of the first format. Based on this, the inclusion of the second identifier in the first MAC CE can indicate that the first MAC CE is a MAC CE of the first format. Conversely, the fact that the first MAC CE does not include the second identifier can indicate that the first MAC CE is a MAC CE of the second format. In one example, the second identifier is used to indicate that the first MAC CE is a MAC CE of the second format. Based on this, the fact that the first MAC CE does not include the second identifier can indicate that the first MAC CE is a MAC CE of the first format. Conversely, the fact that the first MAC CE includes the second identifier can indicate that the first MAC CE is a MAC CE of the second format.

[0219] In some embodiments, the second identifier may be configured by the network device to the terminal; or, it may be pre-defined in the network device and the terminal by a protocol agreement or the like.

[0220] In one embodiment, the second identifier may be a reserved extended logical channel identifier (eLCID). In one embodiment, the second identifier may be an eLCID selected by the network device from an eLCID reserved pool, wherein the eLCID reserved pool may include multiple eLCIDs. The network device may configure the selected eLCID to the terminal as the second identifier.

[0221] In some embodiments, the second identifier may be included in the header of the first MAC CE. In this way, the second identifier can be used to indicate the format of the first MAC CE, and the impact on the first MAC CE can be reduced, thereby simplifying the implementation.

[0222] In some embodiments, the first MAC CE includes first information, and the first information is used to indicate a first bit rate recommended by the network device.

[0223] In some embodiments, the name of the first information is not specifically limited. For example, the first information may be recommended bit rate information, recommended rate information, etc.

[0224] In some embodiments, the first bit rate may be a bit rate for each LCH. In some embodiments, the first bit rate recommended by the network device indicated by the first information may be of LCH granularity, in other words, the terminal may adjust the data rate of a logical channel according to the first bit rate indicated by the first information.

[0225] In some embodiments, the first bit rate may be a bit rate for each DRB. In some embodiments, the first bit rate indicated by the first information may also be DRB granularity, in other words, the terminal may adjust the data rate of a DRB according to the first bit rate indicated by the first information.

[0226] In some embodiments, the first bit rate may be a bit rate for each QoS stream. In some embodiments, the first bit rate indicated by the first information may also be QoS stream granularity, in other words, the terminal may adjust the data rate of a QoS stream according to the first bit rate indicated by the first information.

[0227] In some embodiments, the first MAC CE may include a first identifier and a first bit rate corresponding to the first identifier. In this case, the format of the first MAC CE may be the same as the MAC CE of the second format, but the reserved bit in the first MAC CE may be extended as the first bit, or the reserved bit in the first MAC CE may be extended as the second bit.

[0228] In some embodiments, the first MAC CE may include multiple first identifiers and first bit rates corresponding to the multiple first identifiers. In this case, the format of the first MAC CE may be as follows: Figure 1D Alternatively, the format of the first MAC CE may be as follows: Figure 1E The format shown.

[0229] Step S2102: The terminal determines a first bit rate according to the first MAC CE.

[0230] In some embodiments, the first MAC CE is a MAC CE of a first format.

[0231] In some embodiments, before the terminal determines the first bit rate according to the first MAC CE, the terminal determines the format of the received first MAC CE.

[0232] In some embodiments, the terminal may determine the format of the first MAC CE according to the second identifier included in the first MAC CE. In some embodiments, the terminal may determine the format of the first MAC CE according to different values ​​of the second identifier included in the first MAC CE.

[0233] In some embodiments, the terminal may determine the format of the first MAC CE according to whether the first MAC CE includes a second identifier. In one example, the second identifier is used to indicate that the first MAC CE is a MAC CE of the first format. In some embodiments, when the first MAC CE includes the second identifier, the terminal may determine that the first MAC CE is a MAC CE of the first format. On the contrary, when the first MAC CE does not include the second identifier, the terminal may determine that the first MAC CE is a MAC CE of the second format. In one example, the second identifier is used to indicate that the first MAC CE is a MAC CE of the second format. Based on this, when the first MAC CE includes the second identifier, the terminal may determine that the first MAC CE is a MAC CE of the second format. On the contrary, when the first MAC CE does not include the second identifier, the terminal may determine that the first MAC CE is a MAC CE of the first format.

[0234] In some embodiments, the terminal determines the first bit rate indicated by the first MAC CE according to the first set, wherein the first MAC CE is a MAC CE of the first format. It should be noted that, when the protocol stipulates that the value of the recommended bit rate indicated by the MAC CE of the first format is determined according to the first set, after determining that the received first MAC CE is a MAC CE of the first format, the terminal can determine the bit rate value corresponding to the index indicated by the first MAC CE according to the first set, and determine the bit rate value as the value of the first bit rate.

[0235] In some embodiments, the terminal may receive first indication information sent by a network device, and determine, based on the first indication information, whether to use the first set or the second set to determine the value of the first bit rate indicated by the first MAC CE, wherein the first MACCE is a MAC CE in a first format. It should be noted that, in the case where the value of the recommended bit rate indicated by the MAC CE in the first format can be determined by the first set or the second set, the network device may send the first indication information to the terminal, so that the terminal device determines, based on the first indication information, which set of the first set and the second set to use to determine the bit rate value corresponding to the index indicated by the first MACCE.

[0236] In some embodiments, the terminal determines whether to use the first set or the second set to determine the value of the first bit rate indicated by the first MAC CE based on the bit value of the second bit in the first MAC CE. The first MAC CE is a MAC CE of the first format. It should be noted that, in the case where the value of the recommended bit rate indicated by the MAC CE of the first format can be determined by the first set or the second set, the reserved bit (i.e., the second bit) in the first MAC CE can be extended as an indication bit to use different bit values ​​of the second bit to indicate that the terminal determines the value of the first bit rate through the first set or the second set. After the terminal determines that the received first MAC CE is a MAC CE of the first format, it can determine which set of the first set and the second set to determine the bit rate value corresponding to the index indicated by the first MAC CE based on the bit value of the second bit in the first MAC CE.

[0237] In some embodiments, the terminal may determine, based on the third information sent by the network device, whether to use the first set or the second set to determine the value of the first bit rate indicated by the first MAC CE.

[0238] In some embodiments, when the third information is used to instruct the terminal to use an extended BSR table to report the BSR, the terminal determines to use the first set to determine the value of the first bit rate indicated by the first MAC CE.

[0239] In some embodiments, when the third information is used to indicate that the terminal does not use the extended BSR table to report the BSR, the terminal determines to use the second set to determine the value of the first bit rate indicated by the first MAC CE.

[0240] In some embodiments, the first set may be configured by the network device to the terminal; or, the first set may be pre-defined in the network device and the terminal by protocol agreement or the like.

[0241] In some embodiments, the terminal may determine a value of the first bit rate indicated by the first MAC CE according to the fifth set.

[0242] In some embodiments, the correspondence between the index indicated by the fifth set and the bit rate value is determined based on the maximum bit rate value, the minimum bit rate value and the number of indexes.

[0243] In some embodiments, the terminal may determine multiple indexes in the fifth set and bit rate values ​​corresponding to the multiple indexes according to the maximum bit rate value, the minimum bit rate value and the number of indexes.

[0244] In some embodiments, the terminal may receive the seventh information sent by the network device, and the seventh information is used by the terminal to generate the fifth set; the seventh information may be used to indicate the maximum bit rate value, the minimum bit rate value, and the number of indexes required to generate the fifth set. It should be noted that when the terminal receives the seventh information sent by the network device, indicating that the value of the recommended bit rate indicated by the MAC CE of the first format can be determined according to the fifth set, the terminal needs to generate the fifth set based on the seventh information to correctly decode the received MAC CE of the first format.

[0245] In some embodiments, the terminal may send eighth information to the network device, and the eighth information is used by the network device to generate the fifth set; the eighth information may be used to indicate the maximum bit rate value, the minimum bit rate value, and the number of indexes required to generate the fifth set. It should be noted that after generating the fifth set, the terminal may send the eighth information to the network device so that the network device generates the fifth set according to the eighth information, so that the network device and the terminal reach a consistent understanding of the multiple bit rate values ​​contained in the fifth set and the indexes corresponding to the multiple bit rate values.

[0246] In some embodiments, when the first MAC CE does not include the X field, the terminal may determine the first bit rate according to the bit rate value corresponding to the index indicated by the first MAC CE. In some embodiments, when the protocol stipulates that the reserved bits of the MAC CE of the first format include bits of the X field, it indicates that the X field in the MAC CE of the first format is cancelled. In other words, the X field is no longer used to indicate whether the recommended bit rate indicated by the MAC CE of the first format is determined by the multiplication factor. In this case, the recommended bit rate indicated by the MAC CE of the first format is determined by the bit rate value corresponding to the index.

[0247] In some embodiments, the first MAC CE includes an X field, and the X field is used to indicate whether the first bit rate is determined by the multiplication factor. In one example, the X field includes an indication bit, and different bit values ​​of the indication bit are used to indicate whether the first bit rate is determined by the multiplication factor.

[0248] In some embodiments, when the X field indicates that the first bit rate is not determined by a multiplication factor, the terminal may determine the first bit rate according to a bit rate value corresponding to an index indicated by the first MAC CE.

[0249] In some embodiments, when the X field indicates that the first bit rate is determined by a multiplication factor, the terminal may determine the first bit rate according to the product of the first multiplication factor and the bit rate value corresponding to the index.

[0250] In some embodiments, when the X domain indicates that the first bit rate is determined by a multiplication factor, the terminal may determine, based on the second indication information sent by the network device, whether to determine the first bit rate based on the product of the first multiplication factor and the bit rate value corresponding to the index, or to determine the first bit rate based on the product of the second multiplication factor and the bit rate value corresponding to the index. In some embodiments, the recommended bit rate indicated by the MAC CE of the first format may be determined by the product between the first multiplication factor and the bit rate value indicated by the index, or by the product between the second multiplication factor and the bit rate value indicated by the index. In this case, the terminal may determine whether to use the first multiplication factor or the second multiplication factor based on the second indication information sent by the network device, so that the terminal and the network device reach a consistent understanding of the multiplication factor used in the process of determining the actual value of the recommended bit rate indicated by the MAC CE of the first format.

[0251] In some embodiments, when the X field indicates that the first bit rate is determined by a multiplication factor, the terminal determines whether to determine the first bit rate according to the product of the first multiplication factor and the bit rate value corresponding to the index, or to determine the first bit rate according to the product of the second multiplication factor and the bit rate value corresponding to the index, according to the bit value of the second bit in the first MAC CE. In some embodiments, the reserved bit (i.e., the second bit) in the first MAC CE can be extended as an indication bit to indicate the terminal to use the first multiplication factor or the second multiplication factor using different bit values ​​of the second bit. In this case, the terminal can determine whether to use the first multiplication factor or the second multiplication factor according to the second bit of the first MAC CE, so that the terminal and the network device reach a consistent understanding of the multiplication factor used in the process of determining the actual value of the recommended bit rate indicated by the MAC CE of the first format.

[0252] In some embodiments, when the X field indicates that the first bit rate is determined by a multiplication factor, the terminal can determine, based on the third information sent by the network device, whether to determine the first bit rate based on the product of the first multiplication factor and the bit rate value corresponding to the index, or to determine the first bit rate based on the product of the second multiplication factor and the bit rate value corresponding to the index.

[0253] In some embodiments, when the third information is used to instruct the terminal to use an extended BSR table to report the BSR, the terminal determines the first bit rate according to the product of the first multiplication factor and the bit rate value corresponding to the index.

[0254] In some embodiments, when the third information is used to indicate that the terminal does not use the extended BSR table to report the BSR, the terminal determines the first bit rate according to the product of the second multiplication factor and the bit rate value corresponding to the index.

[0255] In some embodiments, when the terminal determines to use the first multiplication factor, the terminal may determine the value of the first multiplication factor according to multiple parameter values ​​associated with the MAC CE in the first format. In one example, the terminal may determine the value of the first multiplication factor according to the third set.

[0256] In some embodiments, when the terminal determines to use the first multiplication factor, the terminal may receive third indication information sent by the network device, and the third indication information is used to determine the value of the first multiplication factor. It should be noted that the MAC CE of the first format is associated with multiple parameter values, and the value of the first multiplication factor is determined by the parameter value associated with the MAC CE of the first format. The terminal may determine the first parameter value from the multiple parameter values ​​according to the third indication information, and determine the value of the first multiplication factor according to the first parameter value, so as to subsequently determine the first recommended value according to the first multiplication factor.

[0257] In one example, the third indication information may be used to indicate a sequence number of the parameter value. The terminal determines the first parameter value from the multiple parameter values ​​according to the sequence number indicated by the third indication information.

[0258] In some embodiments, when the terminal determines to use the first multiplication factor, the terminal may determine the third multiplication factor as the first multiplication factor; or, the terminal may determine the first multiplication factor based on the product of the third multiplication factor and the second multiplication factor. It should be noted that, when the protocol stipulates that there is a third multiplication factor or the network device configures the third multiplication factor for the terminal, the third multiplication factor can be directly used as the multiplication factor associated with the MAC CE of the first format to determine the first bit rate. Alternatively, the product of the existing multiplication factor (i.e., the second multiplication factor) and the third multiplication factor can be used as the multiplication factor associated with the MAC CE of the first format to determine the first bit rate.

[0259] In some embodiments, the terminal may determine the indicator bit used to indicate the index in the MAC CE of the first format according to the protocol agreement, thereby determining the bit value of the indicator bit in the received first MAC CE and determining the index indicated by the first MAC CE.

[0260] In some embodiments, the MAC CE of the first format may include at least one first bit, where the first bit is a reserved bit of the MAC CE of the first format. The at least one first bit is used to indicate indexes corresponding to multiple bit rate values.

[0261] In some embodiments, when the first bit includes a bit of the X field, the terminal may determine the first bit rate according to the bit rate value corresponding to the index indicated by the first MAC CE. It should be noted that when the first bit includes a bit of the X field, it indicates that the X field in the MAC CE of the first format is cancelled. In other words, the X field is no longer used to indicate whether the recommended bit rate indicated by the MAC CE of the first format is determined by the multiplication factor. In this case, the recommended bit rate indicated by the MAC CE of the first format is determined by the bit rate value corresponding to the index.

[0262] In some embodiments, when the first MAC CE includes multiple information field pairs, the terminal can determine the first identifier and the first bit rate corresponding to the first identifier based on the first information field and the second information field in each information field pair, thereby adjusting the rate of the LCH, DRB or Qos flow indicated by the first identifier according to the first bit rate corresponding to the first identifier.

[0263] In some embodiments, when the first MAC CE is a MAC CE in the second format, the terminal may determine the value of the first bit rate according to the second set.

[0264] In some embodiments, the term "information" can be interchangeably with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0265] In some embodiments, the term "send" can be interchangeable with terms such as "transmit", "report", and "transmit".

[0266] Figure 2B FIG. 2 is an interactive schematic diagram of an information processing method according to an exemplary embodiment. Figure 2B As shown, the embodiment of the present disclosure relates to an information processing method, which is used in a communication system 100, and the method includes:

[0267] Step S2201: The terminal sends a second MAC CE to the network device.

[0268] In some embodiments, the network device receives a second MAC CE sent by the terminal.

[0269] In some embodiments, the second MAC CE may be a MAC CE in the first format. In the embodiments of the present disclosure, the description of the MAC CE in the first format may refer to the description of the MAC CE in the first format in step S2101, which will not be repeated here.

[0270] In some embodiments, in the case where the terminal supports a MAC CE in a first format, the second MAC CE may be a MAC CE in the first format.

[0271] In some embodiments, the second MAC CE may be a MAC CE in the second format. In some embodiments, in the case where the terminal does not support the MAC CE in the first format, the second MAC CE may be a MAC CE in the second format.

[0272] In some embodiments, the second MAC CE includes: a third identifier, the third identifier is used to indicate the format of the second MAC CE. In one embodiment, the third identifier can indicate that the second MAC CE is a MAC CE in the first format. In one embodiment, the third identifier can indicate that the second MAC CE is a MAC CE in the second format. Based on this, the terminal can determine whether the second MAC CE is a MAC CE in the first format or a MAC CE in the second format according to the third identifier.

[0273] In some embodiments, the format of the second MAC CE can be indicated by different values ​​of the third identifier. In one example, the third identifier is a first value (such as 1) to indicate that the second MAC CE is a MAC CE of the first format. The third identifier is a second value (such as 0) to indicate that the second MAC CE is a MAC CE of the second format.

[0274] In some embodiments, the format of the second MAC CE can be indicated by whether it contains a third identifier. In one example, the third identifier is used to indicate that the second MAC CE is a MAC CE of the first format. Based on this, the inclusion of the third identifier in the second MAC CE can indicate that the second MAC CE is a MAC CE of the first format. Conversely, the fact that the second MAC CE does not include the third identifier can indicate that the second MAC CE is a MAC CE of the second format. In one example, the third identifier is used to indicate that the second MAC CE is a MAC CE of the second format. Based on this, the fact that the second MAC CE does not include the third identifier can indicate that the second MAC CE is a MAC CE of the first format. Conversely, the fact that the second MAC CE includes the third identifier can indicate that the second MAC CE is a MAC CE of the second format.

[0275] In some embodiments, the third identifier may be configured by the network device to the terminal; or, it may be pre-defined in the network device and the terminal by a protocol agreement or the like.

[0276] In one embodiment, the third identifier may be a reserved extended logical channel identifier (eLCID). In one embodiment, the third identifier may be an eLCID selected by the network device from an eLCID reserved pool, wherein the eLCID reserved pool may include multiple eLCIDs. The network device may configure the selected eLCID to the terminal as the third identifier.

[0277] In some embodiments, the third identifier may be included in the header of the second MAC CE. In this way, the third identifier can be used to indicate the format of the second MAC CE, and the impact on the second MAC CE can be reduced, thereby simplifying the implementation.

[0278] In some embodiments, the second MAC CE includes fourth information, and the fourth information is used to indicate the first bit rate requested by the terminal.

[0279] In some embodiments, the name of the fourth information is not specifically limited. For example, the first information may be recommended bit rate query information, recommended bit rate inquiry information, etc.

[0280] In some embodiments, the first bit rate may be a bit rate for each LCH. In some embodiments, the first bit rate requested by the terminal indicated by the second information may be of LCH granularity, in other words, the terminal may adjust the data rate of a logical channel according to the first bit rate indicated by the second information.

[0281] In some embodiments, the first bit rate may be a bit rate for each DRB. In some embodiments, the first bit rate requested by the terminal indicated by the second information may also be DRB granularity, in other words, the terminal may adjust the data rate of a DRB according to the first bit rate indicated by the second information.

[0282] In some embodiments, the first bit rate may be a bit rate for each QoS stream. In some embodiments, the first bit rate requested by the terminal indicated by the second information may also be of QoS stream granularity, in other words, the terminal may adjust the data rate of a QoS stream according to the first bit rate indicated by the second information.

[0283] In some embodiments, the second MAC CE may include a first identifier and a first bit rate corresponding to the first identifier. In this case, the format of the second MAC CE may be the same as the MAC CE of the second format, but the reserved bit in the second MAC CE may be extended as the first bit, or the reserved bit in the second MAC CE may be extended as the second bit.

[0284] In some embodiments, the second MAC CE may include multiple first identifiers and first bit rates corresponding to the multiple first identifiers. In this case, the format of the second MAC CE may be as follows: Figure 1D Alternatively, the format of the second MAC CE may be as follows: Figure 1E The format shown.

[0285] In some embodiments, the network device may send fifth information to the terminal, where the fifth information is used to configure the first timer.

[0286] In some embodiments, the first timer is used to prohibit the terminal from sending the second MAC CE during the operation of the first timer. It should be noted that in order to limit the terminal from frequently sending the second MAC CE to the network device, the network device can configure the first timer for the terminal; thereby prohibiting the terminal from sending the second MAC CE to the network device during the operation of the first timer, and after the first timer times out, the terminal can resend the second MAC CE to the network device.

[0287] In some embodiments, the first timer may be an inhibit timer.

[0288] In some embodiments, the terminal may send sixth information to the network device, the sixth information indicating whether the terminal supports the MAC CE in the first format. It should be noted that the terminal sends the sixth information to the network device so that the network device learns whether the terminal supports the MAC CE in the first format.

[0289] In some embodiments, the first timer may include at least one of the following: a second timer, the second timer is configured for each LCH; a third timer, the third timer is configured for each DRB; a fourth timer, the fourth timer is configured for each Qos flow.

[0290] In some embodiments, the network device may determine the first information according to the first bit rate requested by the terminal. It should be noted that if the network device can provide the terminal with the first bit rate requested by the terminal, the network device may determine the first information according to the first bit rate requested by the terminal.

[0291] In some embodiments, the network device may determine the first information by itself. It should be noted that, when the network device cannot provide the terminal with the first bit rate requested by the terminal, the network device may determine the first information according to the first bit rate that the network device can provide.

[0297] In some embodiments, step S2201 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understandable that the network device may actively send the first MAC CE to the terminal without the terminal first sending the second MAC CE to the network device.

[0333] Figure 5 FIG. 3 is an interactive schematic diagram of an information processing method according to an exemplary embodiment. Figure 5 As shown, the embodiment of the present disclosure relates to an information processing method, which is used in a communication system 100, and the method includes one of the following steps:

[0334] Step S5101: The network device sends a first MAC CE to the terminal.

[0335] In some embodiments, the first MAC CE includes first information, and the first information is used to indicate a first bit rate recommended by the network device.

[0336] In some embodiments, the first MAC CE is a MAC CE of a first format, and a value range of a recommended bit rate indicated by the MAC CE of the first format is greater than a value range of a recommended bit rate indicated by the MAC CE of the second format.

[0337] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc., which will not be repeated here.

[0338] In order to better understand the embodiments of the present disclosure, the present disclosure is further described below through some exemplary embodiments.

[0339] In the prior art, a MAC CE for recommending a bit rate has been defined, which is used by a base station to notify a terminal of its recommended bit rate (downlink direction), and is also used by a terminal to inquire a base station for a recommended bit rate (uplink direction).

[0340] In some embodiments, it is necessary to consider using the MAC CE as a congestion indication information to facilitate the terminal to adjust the bit rate. That is, in the downlink direction, the base station notifies the terminal of its recommended bit rate, and the terminal can perform appropriate bit rate adjustment.

[0341] The existing MAC CE of the recommended bit rate calculates a specific bit rate according to a corresponding table, that is, some code points are used for indication, that is, a corresponding relationship between the code points and the values ​​of the bit rate field is established.

[0342] At the same time, a multiplier is also added. When the multiplier is enabled, the multiplier configured by RRC in 331 is multiplied by the bit rate value indicated by the bit rate field to obtain the final recommended bit rate. If the multiplier is not enabled, the multiplier is not multiplied.

[0343] However, in XR services, considering that the rate of XR services is higher, the existing table (such as Table 1 above) only includes 56 indexes, which cannot meet the rate requirements of XR services, so optimization is needed. The present disclosure proposes an enhanced format MAC CE for rate adjustment of XR services.

[0344] Embodiment 1: Introducing an enhanced recommended bit rate command instruction, namely, the first MAC CE.

[0345] Optionally, the instruction adopts a newly defined first MAC CE format, which is different from a second MAC CE format used by the original recommended bit rate.

[0346] This approach has better scalability and does not require consideration of the second MAC CE format used for the original recommended bit rate.

[0347] Optionally, the instruction may adopt the original second MAC CE format and expand some bits for use. This solution is relatively simple, that is, the size of the second MAC CE format is maintained, but only some reserved bits are expanded to new usage purposes during design.

[0348] Optionally, the instruction is for a specific type of service, such as an XR service.

[0349] Optionally, the instruction may be used to instruct the base station to notify the terminal of a recommended bit rate that it can provide.

[0350] Optionally, the instruction may be used for the terminal to notify the base station of the recommended bit rate it requests.

[0351] Embodiment 2, based on embodiment 1, the network or protocol agrees on the value of the bit rate field (Bit Rate field).

[0352] Optionally, the protocol defines a new bit rate field table (ie, the first table) for a specific type of service.

[0353] Optionally, a new bit rate field table (i.e., the first table) defined for a specific type of service has the same number of codepoints as an existing bit rate field table (i.e., the second table) in the protocol, but the corresponding value ranges of the codepoints are different.

[0354] In one example, considering that the rate of the XR service is relatively high, the value range of the bit rate corresponding to the code point in the first table is greater than the value range of the bit rate corresponding to the same code point in the second table.

[0355] In one example, considering that the rate of the XR service is relatively high, the value range of the bit rate corresponding to the code point in the first table, the first code point can be encoded from the Bit Rate field corresponding to 200 or more in the original table.

[0356] Optionally, a new bit rate field table (i.e., a first table) defined for a specific type of service has a different number of code points from an existing bit rate field table (i.e., a second table) in the protocol. For example, the number of code points included in the first table is greater than 56. For example, increasing the indicator bits to 8 can indicate 256 code points.

[0357] Optionally, the network indicates whether the indicated bit rate is determined according to the value of the bit rate field of the first table or the value of the bit rate field of the second table. The network can be configured through RRC signaling (the granularity can be terminal, MAC entity, LCH, etc.). The network can also indicate through a bit field in the MAC CE.

[0358] In some embodiments, in order to utilize more bits to extend the code point, it may be considered to use other fields in the original MAC CE as extended code points.

[0359] Optionally, the bit rate multiplier field, that is, the X field in the 5G NR recommended bit rate MAC CE, is cancelled for use in extended code points. Only the bit rate field is used to indicate the rate, and the steps of multiplying the multiplier in the original mechanism are omitted, which is simpler.

[0360] In one embodiment, the bit field uses 8 bits (e.g., 6 bits of the bit rate field in the 5G NR recommended bit rate MAC CE + the multiplication factor field + the R field). Based on this, 2 bits are added to the original 6 bits, which can be used to indicate more code points.

[0361] Optionally, an algorithm for designing the index of the bit rate field and the indicated bit rate is shown in expression (1):

[0362] Where p = (B max / B min ) 1 / (N-1) -1; (1)

[0363] Among them, B min is the minimum bit rate value, B max is the maximum bit rate value, N is the value from B min To B max The number of values ​​of the amount of data, is an upward value function, where k is an integer greater than or equal to 0, and k is less than or equal to N.

[0364] In one example, assuming the bit rate is in kbit / s, B min =20, B max =1600000, N=254, the corresponding relationship between the corresponding index and the indicated bit rate is shown in Table 2.

[0365]

[0366] Table 2

[0367] Embodiment 3, the multiplication factor (Bit Rate Multiplier) used by the terminal is extended to determine the final recommended bit rate.

[0368] Optionally, the existing multiplication factor can be extended to a wider range to meet the high-rate requirements of XR services. For example, the existing multiplication factor values ​​are only 40, 70, 100 and 200, which is relatively rough. The value range can be increased or a more refined spacing expression can be adopted. For example, the extended multiplication factor values ​​can be 20, 30, 40, 70, 100, 150 and 200, etc.

[0369] Optionally, a new multiplication factor (bitRateMultiplier') may be introduced based on the existing multiplication factors.

[0370] In one example, the terminal may directly use the new multiplication factor to obtain a finer calculation granularity.

[0371] In one example, the terminal may multiply the existing multiplication factor by a new multiplication factor to expand the value range.

[0372] In embodiment 4, the enhanced recommended bit rate command instruction may indicate a per LCH granularity, a per DRB granularity, or a per Qos flow granularity.

[0373] In embodiment 5, the enhanced recommended bit rate command instruction may carry information on at least one LCH or DRB or Qos flow at the same time.

[0374] Optionally, the first MAC CE may carry multiple information field pairs, each of which indicates an LCHID and a corresponding recommended bit rate, such as Figure 1D shown.

[0375] Optionally, in order to save the indication overhead of the LCH / DRB / Qos flow ID, a bitmap may be used for expression; wherein the LCH / DRB / Qos flow ID index may be arranged in ascending or descending order, such as Figure 1E shown.

[0376] In one example, N bits (e.g., 32 bits) may be used for the LCH ID, wherein the bit position corresponding to the LCH that does not enable the enhanced recommended bit rate command instruction function is 0; and the bit position corresponding to the LCH that enables the function is 1, which also means that the LCH has a corresponding recommended bit rate indication; otherwise, the LCH has no recommended bit rate indication.

[0377] In one example, in order to reduce signaling overhead, the bitmap only indicates the LCHs that enable the function, and the LCHs may be arranged in ascending or descending order according to the LCHID index.

[0378] In Embodiment 6, for the first MAC CE, a reserved eLCID is added thereto to indicate the format of the first MAC CE.

[0379] In Embodiment 7, if the first MAC CE reuses the second MAC CE format of the original recommended bit rate, the reserved bits therein can be extended for use.

[0380] In one embodiment, the network indicates whether to enable the reserved bit in the second MAC CE format of the original recommended bit rate to extend the function used, that is, the terminal can use the reserved bit only when the function is enabled.

[0381] Embodiment 8: In order to increase the number of code points in the first table, the reserved bits in the second MAC CE format may be extended or new bits may be added.

[0382] Optionally, the reserved bit may be a bit in the R domain, or a bit in the UL / DL domain.

[0383] It should be noted that if the recommended bit rate instruction is only used for downlink, the bit in the UL / DL domain can be used as an indicator code point.

[0384] In Embodiment 9, the reserved bit may be used to indicate whether the recommended bit rate indicated by the MAC CE is determined according to the value of the bit field in the first table or the value of the bit field in the second table.

[0385] In one embodiment, the indication may be indicated by one of the R fields in the MAC CE. If the bit of the R field is 0, the second table is used; if the bit of the R field is 1, the first table is used. Alternatively, if the bit of the R field is 1, the second table is used; if the bit of the R field is 0, the first table is used.

[0386] In one embodiment, the indication may be indicated by a bit in the UL / DL domain in the MAC CE. If the bit in the UL / DL domain is 0, the second table is used, and if the bit in the UL / DL domain is 1, the first table is used. Alternatively, if the bit in the UL / DL domain is 1, the second table is used, and if the bit in the UL / DL domain is 0, the first table is used.

[0387] In Embodiment 10, the network may explicitly indicate the parameters used for the LCH / DRB / Qos flow, for example, whether the recommended bit rate is determined according to the first table or the second table, or whether the multiplication factor uses the original multiplication factor or the extended multiplication factor.

[0388] In embodiment 11, the network may also implicitly indicate the parameters used for the LCH / DRB / Qos flow, for example, whether the recommended bit rate is determined according to the first table or the second table, or whether the multiplication factor uses the original multiplication factor or the extended multiplication factor.

[0389] In one embodiment, the existing indication message (e.g., additionalBSR-TableAllowed) can be reused to indicate whether the value of the recommended bit rate is determined according to the first table or the second table. It can be understood that only the logical channel using the extended BSR table means that the rate of the logical channel is larger, and the first table needs to be used at this time.

[0390] Based on this, by adopting the implicit notification method, there is no need to use additional signaling to indicate whether the recommended bit rate is determined according to the first table or the second table. Or, whether the multiplication factor uses the original multiplication factor or the extended multiplication factor.

[0391] In one example, if the logical channel is configured with a table using an extended BSR, it means that the network indicates that the value of the recommended bit rate indicated is determined according to the first table, otherwise the value of the recommended bit rate is still determined according to the second table.

[0392] Embodiment 12: In order to limit the terminal from frequently sending requests for the recommended bit rate, the prohibition timer may be started per LCH, per DRB or per Qos flow.

[0393] Embodiment 13, based on embodiment 1, introduces new terminal capabilities to support the enhanced recommended bit rate instruction and the above process.

[0394] The embodiments of the present disclosure also provide a device for implementing any of the above methods, for example, a device is provided, the above device includes a unit or module for implementing each step performed by the terminal in any of the above methods.
