[0038] In a first aspect, the embodiments of the present disclosure provide a method of processing information, wherein the method is performed by a network device, and the method comprises: sending, to a terminal, a first medium access control (MAC) control element (CE); wherein the first MAC CE comprises first information, the first information being 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 the first format of the MAC CE indicates a value range of the recommended bit rate that is greater than a value range of a recommended bit rate indicated by a MAC CE of a second format.

[0039] In the above embodiments, the network device sends the first MAC CE to the terminal, so as 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 the MAC CE of the first format, compared with the MAC CE of the second format, the network device can indicate a value range of the recommended bit rate that is greater through the MAC CE of the first format, so as to meet the high-rate requirement of a specific type of service (such as an XR service) of the terminal, so as to facilitate the rate adjustment of the specific type of service of the terminal, so as to alleviate the degree of network congestion.

[0040] In some embodiments of the first aspect, in some embodiments, the first set of MAC CEs of the first format is associated with determining the value of the first bit rate; the first set comprises a plurality of bit rate values and indexes corresponding to the plurality of bit rate values.

[0041] In the above embodiments, a new first set is introduced for the MAC CEs of the first format, and the value of the first bit rate indicated by the MAC CEs of the first format can be determined by the first set. The first set comprises a plurality of bit rate values and indexes corresponding to the plurality of bit rate values. In the case where the first MAC CE is of the first format, the value of the first bit rate indicated by the first MAC CE can be determined by the correspondence between the indexes and the bit rate values described by the first set, so that the value of the first bit rate indicated by the first MAC CE is known.

[0042] In some embodiments of the first aspect, in some embodiments, the MAC CE of the first format comprises 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 the indexes corresponding to the plurality of bit rate values.

[0043] In the above embodiments, 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 for indicating the indexes corresponding to the plurality of bit rate values, so as to increase the number of indication bits of the bit rate field in the MAC CE of the first format, and increase the range of the value of the recommended bit rate indicated by the MAC CE of the first format.

[0044] In some embodiments of the first aspect, in some embodiments, the MAC CE of the first format is associated with a first product factor; the first product factor is used to determine the first bit rate.

[0045] In the above embodiments, a new product factor (i.e. the first product factor) is introduced for the MAC CEs of the first format. In the case where the first MAC CE is of the first format, the first bit rate can be determined by the first product factor and the bit rate value corresponding to the index indicated by the first MAC CE; so as to further expand the range of the value of the first bit rate indicated by the first MAC CE by using the first product factor.

[0046] In some embodiments of the first aspect, the method further comprises: sending second information to the terminal, the second information comprising at least one of the following: first indication information, used to instruct the terminal to determine the value of the first bit rate by using the first set or a second set; wherein the second set is different from the first set; second indication information, used to instruct the terminal to use a first product factor or a second product factor; wherein the first product factor is different from the second product factor.

[0047] In the above embodiments, 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 in the first set or the correspondence described in the second set; in this case, the network device can send first indication information to the terminal, so that the network device and the terminal 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 second indication information to the terminal, so that the network device and the terminal reach a consistent understanding on whether the product factor of the first MAC CE is the first product factor or the second product factor. In this way, the first MAC CE sent by the network device can be correctly decoded by the terminal.

[0048] In some embodiments of the first aspect, the MAC CE of the first format includes: a second bit, the second bit being a reserved bit in the MAC CE of the first format; the second bit being used to indicate at least one of the following: the terminal determines the value of the first bit rate by the first set or the second set; the second set being different from the first set; the terminal uses the first product factor or the second product factor; the first product factor being different from the second product factor.

[0049] In the above embodiments, 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 product factor of the first MAC CE is the first product factor or the second product factor. The embodiments of the present disclosure use the reserved bit of the MAC CE of the first format to indicate the above information without the need for the network device to additionally send indication information to the terminal, so that the network device and the terminal reach a consistent understanding on the above information, so that the first MAC CE sent by the network device can be correctly decoded by the terminal.

Since the extended BSR table indicates a larger range of buffer sizes, if the third information indicates that the terminal uses the extended BSR table for BSR reporting, it indicates that the data rate of the logical channel is high. In this case, 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 through the first set, and / or, the product factor of the first MAC CE should be the first product factor, thus expanding the range of values ​​of the first bit rate that the first MAC CE can indicate.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the first bit rate is any one of the following: the bit rate for each logical channel (LCH); the bit rate for each data radio bearer (DRB); or the bit rate for each quality of service (QoS) stream.

[0123] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), wherein the CU can also be referred to as a control unit (control unit). The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers are controlled by the CU, and the rest or all of the protocol layers are distributed in the DU and controlled by the CU, but is not limited thereto.

Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0131] In some embodiments, the terminal sends a request to the base station for recommended bit rate. In an example, as shown in FIG. IB, which is a schematic diagram of an interaction between a terminal and a network device for recommended bit rate according to an example embodiment, the terminal sends a MAC CE to the base station, which includes a recommended bit rate query message. The terminal receives a MAC CE from the base station carrying a recommended bit rate, so that the terminal can adjust the codec rate when the network is congested.

[0132] In some embodiments, as shown in FIG. 1C, which is a schematic diagram of a format of a MAC CE according to an example embodiment, the MAC CE can include an LCID field, an Uplink (UL) / Downlink (DL) field, a Bit Rate field, an X field, and an R field.

[0133] In some embodiments, the LCID field is used to indicate the identity of a logical channel to which the recommended bit rate information or the recommended bit rate query information applies; the LCID field has a length of 6 bits.

[0134] In some embodiments, the UL / DL field is used to indicate whether the recommended bit rate information or the recommended bit rate query information applies to uplink or downlink. The UL / DL field has a length of 1 bit. A bit value of 0 of the UL / DL field can indicate that the recommended bit rate information or the recommended bit rate query information applies to downlink, and a bit value of 1 of the UL / DL field can indicate that the recommended bit rate information or the recommended bit rate query information applies to uplink.

[0135] In some embodiments, the Bit Rate field can indicate the recommended bit rate information or the recommended bit rate query information. The Bit Rate field has a length of 6 bits. In an embodiment, in the case that the MAC CE contains the recommended bit rate information, the Bit Rate field is used to indicate the recommended bit rate value. In an embodiment, in the case that the MAC CE contains the recommended bit rate query information, the Bit Rate field is used to indicate the recommended bit rate value requested by the terminal. In an embodiment, the recommended bit rate value can be from a set of bit rate values (such as the second set) associated with the MAC CE, as shown in Table 1 below, wherein the set of bit rate values includes 56 bit rate values. In an embodiment, each bit rate value in the set of bit rate values is associated with an index. Based on this, the recommended bit rate value can be indicated by the index included in the Bit Rate field.

[0136] In some embodiments, the X field, i.e., the bit rate multiplier field, for terminals supporting the recommended bit rate multiplier parameter, when the LCID field indicates the logical channel configuration bit rate multiplier 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.

[0137] In some embodiments, the R field, i.e., the reserved field, the bit value of the R field is set to 0.

[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 of the above format (hereinafter referred to as the second format of the MAC CE) can only indicate the bit rate values corresponding to 56 indexes, and the value range of the bit rate value is small. For some specific types of services, such as XR services, because the rate of the XR service is larger, the value range of the bit rate value indicated by the second format of the MAC CE cannot meet the rate requirement of the XR service, and therefore needs to be optimized.

[0140] 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 realize the enhancement of the MAC CE, so as to meet the rate requirement of the XR service and improve the reliability of the system.

[0141] FIG. 2A is an interaction schematic diagram I of an information processing method according to an exemplary embodiment. As shown in FIG. 2A, the embodiments of the present disclosure relate to an information processing method for a communication system 100, the method comprising:

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

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

[0144] In some embodiments, the first MAC CE can be a first format of MAC CE. In an embodiment, the first format of MAC CE can be an enhanced format of MAC CE, used for rate adjustment of the XR service.

[0145] In some embodiments, the range of values of the recommended bit rate indicated by the MAC CE of the first format is larger than the range of values of the recommended bit rate indicated by the MAC CE of the second format. In an embodiment, for a first type of service with higher data rate requirement, such as XR service, the MAC CE of the first format can be used as the 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 of the second format, the range of values of the recommended bit rate indicated by the MAC CE of the first format can satisfy the high rate requirement of the first type of service (such as XR service) and improve the reliability of the system.

[0146] In some embodiments, the terminal or the network device can select one or more values of the recommended bit rate from the first set as the values of the recommended bit rate indicated by the MAC CE of 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 an embodiment, the range of values of the recommended bit rate indicated by the MAC CE of the first format is larger than the range of values of the recommended bit rate indicated by the MAC CE of the second format.

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

[0149] In some embodiments, the number of the plurality of bit rates in the first set can 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 can 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 limited, as long as it can be used to indicate the correspondence between the bit rate values and the indices. For example, the first set can be in the form of a table, which is also used to represent the correspondence between the indices and the bit rate values.

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

[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 the bit rate value corresponding to the same index in the second set. In this case, although the number of indexes contained in the first set is the same as the number of indexes contained in the second set, the range of bit rate values that the first set can indicate is greater than the range of bit rate values that the second set can indicate.

[0153] In some embodiments, the number of indexes contained in the first set is greater than the number of indexes contained 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 since the number of indexes contained in the first set is greater than the number of indexes contained in the second set, the range of bit rate values that the first set can indicate is greater than the range of bit rate values that the second set can indicate.

[0154] In an example, the second set contains 56 bit rate values, as shown in Table 1 above. The number of bit rate values contained in the first set is greater than 56.

[0155] In some embodiments, the first set can be configured by the network device to the terminal; or, it can also be predefined 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. The at least one first bit is used to indicate the indexes corresponding to the plurality of 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, so as to increase the range of recommended bit rates indicated by the MAC CE of the first format.

[0157] In an example, compared with the MAC CE of the second format which can indicate 56 bit rate values, the reserved bit in the MAC CE of the first format can be expanded as an indication bit of the bit rate field, so that the number of indication bits of the bit rate field in the MAC CE of the first format is increased. When the number of indication bits in the bit rate field of the MAC CE of the first format is 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 of the first format can be determined according to the first set. It should be noted that the value of the recommended bit rate indicated by the MAC CE of the first format is determined by the first set. In this case, when the format of the MAC CE is determined, it is determined that the value of the recommended bit rate indicated by the MAC CE is determined by which set, and it is not necessary to additionally indicate whether the recommended bit rate is determined by the first set or the second set through the indication information.

[0159] In some embodiments, the value of the recommended bit rate indicated by the MAC CE of the first format can 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 can be determined by the first set or the second set. In this case, since the correspondence between the index and the bit rate value indicated by the first set is different from the correspondence between the index and the bit rate value indicated by the second set, the network device needs to reach a consensus with the terminal to determine whether the value of the recommended bit rate indicated by the MAC CE of the first format is determined by the first set or the second set, so as to realize correct decoding of 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 can 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 of the first format through the first set or the second set. In some embodiments, in the case that 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 network device can 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 of 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 product factor.

[0162] In some embodiments, the first product 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 according to the product between the bit rate value corresponding to the index and the first product factor.

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

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

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

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

[0167] In some embodiments, the MAC CE of the first format is associated with multiple parameter values, and the MAC CE of the 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, 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, so that the first product factor has a larger value range.

[0168] In some embodiments, the third set associated with the MAC CE of the first format includes multiple parameter values, and the fourth set associated with the MAC CE of the second format includes multiple parameter values. In some embodiments, the fourth set can be a subset of the third set. In some embodiments, the embodiments of the present disclosure can expand the value range of the existing product factor (i.e., the second product factor) to obtain a new value range, and use the new value range as the value range of the first product factor, so as to meet the high rate requirement of the first type of service.

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

[0170] In some embodiments, the multiple parameter values associated with the MAC CE of the first format can be configured by the network device to the terminal; or, the multiple parameter values associated with the MAC CE of the first format can be predefined 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 of the first format can be determined according to a fifth set, and the fifth set can include multiple bit rate values and multiple indexes corresponding to the multiple bit rate values.

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

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

[0174] In some embodiments, the minimum bit rate value can be a minimum value of the recommended bit rate that the network device can provide. Alternatively, the minimum bit rate value can be a 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 indication bits in the MAC CE of the first format for indicating the indexes corresponding to the bit rate values. For example, if 8 indication bits in the MAC CE of the first format are used to indicate the indexes corresponding to the bit rate values, it can be determined that the number of indexes is 256.

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

[0177] In some embodiments, the network device can determine the plurality of indexes in the fifth set and the bit rate values corresponding to the plurality of 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] wherein p = (B max / B min ) 1 / (N-1) -1; (1)

[0180] wherein B min is the minimum bit rate value, B max is the maximum bit rate value, and N is the number of values of the data amount from B min to B max . is a ceiling function. Wherein 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 can send the seventh information to the terminal, and the seventh information is used for the terminal to generate the fifth set; the seventh information can be used to indicate the maximum bit rate value, the minimum bit rate value and the number of indexes required for generating the fifth set. It should be noted that the network device can send the seventh information to the terminal after generating the fifth set, 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 plurality of bit rate values contained in the fifth set and the indexes corresponding to the plurality of bit rate values.

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

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

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

[0185] In some embodiments, the third product factor can be configured by the network device to the terminal; or, the third product factor can also be predefined in the network device and the terminal by means of protocol agreement or the like.

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

[0187] In some embodiments, the recommended bit rate indicated by the MAC CE of the first format can be determined by the product between the first product factor and the bit rate value indicated by the index, or can be determined by the product between the second product factor and the bit rate value indicated by the index. In this case, since the first product factor and the second product factor are different, the network device needs to reach a consistent understanding with the terminal on the product factor used in the determination process of the actual value of the recommended bit rate indicated by the MAC CE of the first format, so as to enable correct decoding of the MAC CE of the first format and determination of the value of the recommended bit rate indicated by the MAC CE of the first format.

[0188] In some embodiments, the network device can send, to the terminal, second indication information, the second indication information being used to indicate whether the terminal uses the first product factor or the second product factor.

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

[0190] In some embodiments, the MAC CE in the first format comprises a second bit, the second bit being a reserved bit in the MAC CE in the first format, the second bit being used to indicate at least one of the following: the terminal determines the value of the recommended bit rate indicated by the MAC CE in the first format by using the first set or the second set; the terminal uses the first product factor or the second product factor. It should be noted that the reserved bit in the MAC CE in the first format can be extended as an indication bit to indicate, by using different bit values of the second bit, that the terminal determines the value of the recommended bit rate indicated by the MAC CE in the first format by using 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 product factor or the second product factor, so that the network device does not need to send additional indication information to the terminal, thereby reducing information overhead.

[0191] In some embodiments, the reserved bit in the MAC CE in the first format can comprise a bit of the R field.

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

[0193] In an embodiment, the first bit in the MAC CE of the first format can comprise a bit of the X field and a bit of the R field. As an example, the network device can 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 and one bit of the X field and one bit of the R field in the MAC CE of the first format are collectively used to indicate the index of the plurality of bit rate values. It should be noted that the indication bit in the MAC CE of the first format for indicating the index can be predefined in the network device and the terminal by protocol convention or the like. When the indication bit in the MAC CE of the first format for indicating the index further comprises a bit of the X field, it is indicated 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 can send third information to the terminal, the third information being used to indicate whether the terminal uses the extended BSR table for BSR reporting.

[0195] In some embodiments, the third information is further used 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.

[0196] In some embodiments, the third information is further used to indicate that the terminal uses the first product factor or the second product factor.

[0197] In some embodiments, the third information is indication information used to indicate whether the terminal uses the extended BSR table, and the network device can multiplex the existing indication information to implicitly indicate which set the terminal uses to determine the value of the recommended bit rate indicated by the MAC CE of the first format, and to indicate that the terminal uses the first product factor or the second product factor. It can be understood that, since the value range of the data amount 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 indicates that the data rate of the logical channel is 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 requirement 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 product factor used in the determination process of the recommended bit rate indicated by the MAC CE of the first format can be the first product factor. If the logical channel used by the terminal is not configured to use the extended BSR table, it indicates that the data rate of the logical channel is small. In this case, the value of the recommended bit rate indicated by the MAC CE of the first format can be determined by the second set, and the product factor used in the determination process of the recommended bit rate indicated by the MAC CE of the first format can be the second product factor.

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

[0199] In some embodiments, the MAC CE in the first format can be used to indicate multiple recommended bit rates.

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

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

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

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

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

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

[0206] In an example, as shown in FIG. 1D, FIG. 1D is a schematic diagram of a first format of MAC CE according to an example embodiment. Each information field pair in the MAC CE in the first format can include an LCID field, an 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 in the first format can be the same as that of the MAC CE in the second format.

[0207] In some embodiments, the MAC CE of the first format can 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 a plurality of fourth information fields. The third information field includes a bitmap, and each bit in the bitmap is associated with a first identifier. Each fourth information field is used to indicate a recommended bit rate corresponding to each first identifier. It should be noted that, in order to save the indication overhead of the first identifiers in the MAC CE of the first format, the plurality of first identifiers can be indicated by a bitmap.

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

[0209] In an example, each bit in the bitmap corresponds to an LCH. A bit corresponding to an LCH having a first bit value indicates that the MAC CE of the first format includes a recommended bit rate corresponding to the LCH; and a bit corresponding to an LCH having a second bit value indicates that the MAC CE of the first format does not include a recommended bit rate corresponding to the LCH.

[0210] In an example, as shown in FIG. IE, which is a schematic diagram of a MAC CE of a first format according to an example embodiment, the MAC CE of the first format includes a third information field and a plurality of fourth information fields. The plurality of bits in the third information field correspond to LCH8 to LCH1, respectively. Each fourth information field can include a bit rate field, an X field, and an R field. The bit rate field in each fourth information field is used to indicate a recommended bit rate corresponding to a bit in the third information field having a first bit value. For example, if the values of the plurality of bits in the third information field are 00101000, the first fourth information field in the two fourth information fields is used to indicate a recommended bit rate corresponding to LCH6, and the second fourth information field is used to indicate a 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 in the bitmap depends on the number of first identifiers. In an embodiment, the bitmap is used to indicate LCHs corresponding to recommended bit rates, instead of all LCHs, so as to reduce the number of bits in the bitmap and reduce the signaling overhead.

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

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

[0214] In some embodiments, before the network device sends the first MAC CE to the terminal, the terminal can send sixth information to the network device, the sixth information indicating whether the terminal supports the first format of the MAC CE. 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 first format of the MAC CE, and thus the network device determines whether to send the first format of the MAC CE or the second format of the MAC CE to the terminal.

[0215] In some embodiments, the name of the sixth information is not specifically limited in the embodiments of the present disclosure. For example, it can be capability information, capability indication information, etc.

[0216] In some embodiments, the first MAC CE includes a second identifier, the second identifier being used to indicate the format of the first MAC CE. In an embodiment, the second identifier can indicate that the first MAC CE is a MAC CE of the first format. In an 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 an example, the second identifier being a first value (such as 1) can indicate that the first MAC CE is a MAC CE of the first format. The second identifier being a second value (such as 0) can 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 the second identifier is included. In an 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 exclusion of the second identifier from the first MAC CE can indicate that the first MAC CE is a MAC CE of the second format. In an 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 exclusion of the second identifier from the first MAC CE can indicate that the first MAC CE is a MAC CE of the first format. Conversely, the inclusion of the second identifier in the first MAC CE can indicate that the first MAC CE is a MAC CE of the second format.

[0219] In some embodiments, the second identity can be configured to the terminal by the network device; or, it can also be predefined in the network device and the terminal by protocol convention or the like.

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

[0221] In some embodiments, the second identity can be contained in the header of the first MAC CE. In this way, the second identity can be used to indicate the format of the first MAC CE in this way, 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 the 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 can be recommended bit rate information, recommended rate information, etc.

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

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

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

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

[0228] In some embodiments, the first MAC CE can include a plurality of first identifiers and a plurality of first bit rates corresponding to the plurality of first identifiers. In this case, the format of the first MAC CE can be the format as shown in FIG. 1D. Alternatively, the format of the first MAC CE can be the format as shown in FIG. 1E.

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

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

[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 can determine the format of the first MAC CE according to the second identifier contained in the first MAC CE. In some embodiments, the terminal can determine the format of the first MAC CE according to different values of the second identifier contained in the first MAC CE.

[0233] In some embodiments, the terminal can determine the format of the first MAC CE according to whether the first MAC CE contains the second identifier. In an example, the second identifier is used to indicate that the first MAC CE is a first format of the MAC CE. In some embodiments, in the case that the first MAC CE contains the second identifier, the terminal can determine that the first MAC CE is a first format of the MAC CE. Conversely, in the case that the first MAC CE does not contain the second identifier, the terminal can determine that the first MAC CE is a second format of the MAC CE. In an example, the second identifier is used to indicate that the first MAC CE is a second format of the MAC CE. Based on this, in the case that the first MAC CE contains the second identifier, the terminal can determine that the first MAC CE is a second format of the MAC CE. Conversely, in the case that the first MAC CE does not contain the second identifier, the terminal can determine that the first MAC CE is a first format of the MAC CE.

[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, in the case where the protocol stipulates that the recommended bit rate indicated by the MAC CE of the first format is determined according to the first set, after the terminal determines 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 can receive first indication information sent by the network device, and determine to use the first set or the second set to determine the value of the first bit rate indicated by the first MAC CE according to the first indication information, wherein the first MAC CE is a MAC CE of the first format. It should be noted that, in the case where the recommended bit rate indicated by the MAC CE of the first format can be determined according to the first set or the second set, the network device can send the first indication information to the terminal, so that the terminal determines which of the first set and the second set to use to determine the bit rate value corresponding to the index indicated by the first MAC CE according to the first indication information.

[0236] In some embodiments, the terminal determines to use the first set or the second set to determine the value of the first bit rate indicated by the first MAC CE according to the bit value of the second bit in the first MAC CE, wherein the first MAC CE is a MAC CE of the first format. It should be noted that, in the case where the recommended bit rate indicated by the MAC CE of the first format can be determined according to 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 indicate the terminal to determine the value of the first bit rate according to the first set or the second set by using different bit values of the second bit. After the terminal determines that the received first MAC CE is a MAC CE of the first format, the terminal can determine which of the first set and the second set to use to determine the bit rate value corresponding to the index indicated by the first MAC CE according to the bit value of the second bit in the first MAC CE.

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

[0238] In some embodiments, in the case where the third information is used to instruct the terminal to use the 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, in the case that the third information is used to indicate that the terminal does not use the extended BSR table for BSR reporting, the terminal determines the value of the first bit rate indicated by the first MAC CE using the second set.

[0240] In some embodiments, the first set can be configured to the terminal by the network device; or, it can also be predefined in the network device and the terminal by protocol agreement or the like.

[0241] In some embodiments, the terminal can determine the 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 can determine the multiple indexes in the fifth set and the 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 can receive the seventh information sent by the network device, and the seventh information is used for the terminal to generate the fifth set; the seventh information can be used to indicate the maximum bit rate value, the minimum bit rate value, and the number of indexes required for generating the fifth set. It should be noted that when the terminal receives the seventh information sent by the network device, it means that the value of the recommended bit rate indicated by the first format of MAC CE can be determined according to the fifth set, and the terminal needs to generate the fifth set based on the seventh information to correctly decode the received first format of MAC CE.

[0245] In some embodiments, the terminal can send the eighth information to the network device, and the eighth information is used for the network device to generate the fifth set; the eighth information can be used to indicate the maximum bit rate value, the minimum bit rate value, and the number of indexes required for generating the fifth set. It should be noted that after generating the fifth set, the terminal can 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, in a case where the first MAC CE does not include the X field, the terminal can determine the first bit rate according to the bit rate value corresponding to the index indicated by the first MAC CE. In some embodiments, in a case where the reserved bit of the MAC CE of the first format according to the protocol convention includes the bit of the X field, it is explained 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 product 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 the X field, and the X field is used to indicate whether the first bit rate is determined by the product factor. In an example, the X field includes one indication bit, and different bit values of the indication bit are used to indicate whether the first bit rate is determined by the product factor.

[0248] In some embodiments, in a case where the X field indicates that the first bit rate is not determined by the product factor, the terminal can determine the first bit rate according to the bit rate value corresponding to the index indicated by the first MAC CE.

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

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

[0251] In some embodiments, in the case that the X field indicates that the first bit rate is determined by a product factor, the terminal determines, according to the bit value of the second bit in the first MAC CE, whether the first bit rate is determined according to the product of the first product factor and the bit rate value corresponding to the index or is determined according to the product of the second product factor and the bit rate value corresponding to the index. 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, by different bit values of the second bit, whether the terminal uses the first product factor or the second product factor. In this case, the terminal can determine, according to the second bit of the first MAC CE, whether to use the first product factor or the second product factor, so that the terminal and the network device reach a consistent understanding of the product factor used in the determination of the actual value of the recommended bit rate indicated by the MAC CE of the first format.

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

[0253] In some embodiments, in the case that the third information is used to indicate that the terminal uses the extended BSR table for BSR reporting, the terminal determines that the first bit rate is determined according to the product of the first product factor and the bit rate value corresponding to the index.

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

[0255] In some embodiments, in the case that the terminal determines to use the first product factor, the terminal can determine the value of the first product factor according to the plurality of parameter values associated with the MAC CE of the first format. In an example, the terminal can determine the value of the first product factor according to the third set.

[0256] In some embodiments, in the case that the terminal determines to use the first product factor, the terminal can receive third indication information sent by the network device, the third indication information being used to determine the value of the first product factor. It should be noted that the value of the first product factor is determined by the parameter values associated with the MAC CE of the first format. The terminal can determine, according to the third indication information, the first parameter value from the plurality of parameter values, determine the value of the first product factor according to the first parameter value, and subsequently determine the first recommended value according to the first product factor.

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

[0258] In some embodiments, in a case where the terminal determines to use the first product factor, the terminal can determine the third product factor as the first product factor; or the terminal can determine the first product factor according to a product of the third product factor and the second product factor. It should be noted that in a case where the third product factor is agreed in the protocol or the network device configures the terminal with the third product factor, the third product factor can be directly used as the product factor associated with the MAC CE of the first format for determining the first bit rate. Or, a product of the existing product factor (i.e., the second product factor) and the third product factor can be used as the product factor associated with the MAC CE of the first format for determining the first bit rate.

[0259] In some embodiments, the terminal can determine the indication bit in the MAC CE of the first format for indicating the index according to the protocol agreement, thereby determining the bit value of the indication 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 can include at least one first bit, and 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 the index corresponding to the plurality of bit rate values.

[0261] In some embodiments, in a case where the first bit includes the bit of the X field, the terminal can 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 the 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 product 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, in a case where the first MAC CE includes a plurality of information field pairs, the terminal can determine the first identifier and the first bit rate corresponding to the first identifier according to the first information field and the second information field in each information field pair, and adjust 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, in a case where the first MAC CE is the MAC CE of the second format, the terminal can determine the value of the first bit rate according to the second set.

[0264] In some embodiments, the term “information” can be mutually interchangeable with the terms “message”, “signal”, “signaling”, “report”, “configuration”, “indication”, “instruction”, “command”, “channel”, “parameter”, “field”, “data”, and the like.

[0265] In some embodiments, the term “sending” can be mutually interchangeable with the terms “transmitting”, “reporting”, “transferring”, and the like.

[0266] FIG. 2B is a second interaction diagram illustrating a method of processing information according to an example embodiment. As shown in FIG. 2B, the embodiments of the present disclosure relate to a method of processing information, for the communication system 100, the method comprising:

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

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

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

[0270] In some embodiments, in the case that the terminal supports the MAC CE of the first format, the second MAC CE can be the MAC CE of the first format.

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

[0272] In some embodiments, the second MAC CE comprises a third identifier, the third identifier being used to indicate the format of the second MAC CE. In an embodiment, the third identifier can indicate that the second MAC CE is the MAC CE of the first format. In an embodiment, the third identifier can indicate that the second MAC CE is the MAC CE of the second format. Based on this, the terminal can determine whether the second MAC CE is the MAC CE of the first format or the MAC CE of 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 an example, the third identifier being a first value (e.g., 1) can indicate that the second MAC CE is a MAC CE of the first format. The third identifier being a second value (e.g., 0) can 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 the third identifier is included. In an 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 third identifier being included in the second MAC CE can indicate that the second MAC CE is a MAC CE of the first format. Conversely, the second MAC CE not including the third identifier can indicate that the second MAC CE is a MAC CE of the second format. In an 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 second MAC CE not including the third identifier can indicate that the second MAC CE is a MAC CE of the first format. Conversely, the second MAC CE including 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 can be configured to the terminal by the network device; or, it can also be predefined in the network device and the terminal by protocol agreement or the like.

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

[0277] In some embodiments, the third identifier can 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 at the same time, 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 can be recommended bit rate query information, recommended bit rate inquiry information, etc.

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

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

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

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

[0284] In some embodiments, the second MAC CE can include a plurality of first identifiers and a plurality of first bit rates corresponding to the plurality of first identifiers. In this case, the format of the second MAC CE can be as shown in FIG. 1D. Alternatively, the format of the second MAC CE can be as shown in FIG. 1E.

[0285] In some embodiments, the network device can send the fifth information to the terminal, and 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 running 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; so as to prohibit the terminal from sending the second MAC CE to the network device during the running of the first timer, after the first timer expires, the terminal can send the second MAC CE to the network device again.

[0287] In some embodiments, the first timer can be a prohibit timer.

[0288] In some embodiments, the terminal can send sixth information to the network device, the sixth information indicating whether the terminal supports the first format of MAC CE. 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 first format of MAC CE.

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

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

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

[0333] FIG. 5 is an interaction diagram three of a method of information processing according to an example embodiment. As shown in FIG. 5, the embodiments of the present disclosure relate to a method of information processing, which is used in the communication system 100, and the method comprises 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 comprises 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 the first format indicates a range of values of the recommended bit rate that is larger than a range of values of the recommended bit rate indicated by the second format.

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

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

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

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

[0341] The existing MAC CE for recommended bit rate is calculated according to a corresponding table to obtain a specific bit rate, that is, some code points are used to indicate, 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 multiplication factor (Bit Rate Multiplier) is also attached. When the multiplication factor is enabled, the multiplication factor configured by the RRC in 331 and the bit rate value indicated by the bit rate field are multiplied to obtain the final recommended bit rate, and if the multiplication factor is not enabled, the multiplication factor is not multiplied.

[0343] However, in XR services, considering that the rate of XR services is larger; the existing table (such as Table 1 in the above) only includes 56 indexes, which cannot meet the rate requirement of XR services, and therefore needs to be optimized. The present disclosure proposes a MAC CE of an enhanced format for rate adjustment of XR services.

[0344] Embodiment 1: Introducing an enhanced recommended bit rate command instruction, that is, a first MAC CE.

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

[0346] In this way, the extension is better, and there is no need to consider the second MAC CE format used by the original recommended bit rate.

[0347] Alternatively, the instruction can extend the use of part of the bits in the original second MAC CE format. In this scheme, it is relatively simple, that is, the size of the second MAC CE format is maintained, but only part of the reserved bits is extended to a new use purpose when designed.

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

[0349] Alternatively, the instruction can be used to indicate that the base station informs the terminal of the recommended bit rate it can provide.

[0350] Alternatively, the instruction can be used to indicate that the terminal informs 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.

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

[0353] Alternatively, the new table of the bit rate field (i.e. the first table) defined for a specific type of service has the same number of code points as the existing table of the bit rate field (i.e. the second table) in the protocol, but the value range corresponding to the code points is different.

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

[0355] In an example, considering that the rate of XR service is large, the value range of the bit rate corresponding to the code points in the first table is greater than the value range of the bit rate corresponding to the same code points in the second table.

[0356] Alternatively, the new table of the bit rate field (i.e. the first table) defined for a specific type of service has a different number of code points than the existing table of the bit rate field (i.e. the second table) in the protocol. For example, the first table contains more than 56 code points. For example, 8 indication bits are added, which 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 configure (the granularity can be a terminal, a MAC entity, an LCH, etc.) through RRC signaling. The network can also indicate through a bit field in the MAC CE.

[0358] In some embodiments, in order to expand the code point with more bits, the use of other fields in the original MAC CE can be considered as an extension of the code point.

[0359] Optionally, the product factor (Bit Rate Multiplier) field, i.e. the X field in the 5G NR Recommended Bit Rate MAC CE, is used for expanding the code point. Only the bit rate field is used to indicate the rate, and the step of multiplying the product factor in the original mechanism is 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 + product factor field + R field). Based on this, i.e. on the basis of the original 6 bits, 2 bits are added, which can be used to indicate more code points.

[0361] Optionally, an algorithm for designing an 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] where B min is the minimum bit rate value, B max is the maximum bit rate value, N is the number of values of the data amount from B min to B max , is a value-up function. Wherein k is an integer greater than or equal to 0, and k is less than or equal to N.

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

[0365] Table 2

[0366] Embodiment 3: The product factor (Bit Rate Multiplier) is extended for the terminal to determine the final recommended bit rate.

[0367] Optionally, the existing product factor can be extended to a larger range to meet the high speed requirement of XR service. For example, the existing product factor only takes values of 40, 70, 100 and 200; it is relatively rough; then the value range can be increased or a more refined interval expression can be adopted. For example, the extended product factor can take values of 20, 30, 40, 70, 100, 150 and 200, etc.

[0368] Optionally, a new product factor (bitRateMultiplier’) can be introduced on the basis of the existing product factor.

[0369] In an example, the terminal can directly use the new product factor to obtain a finer calculation granularity.

[0370] In an example, the terminal can multiply the new product factor on the basis of the existing product factor to expand the value range.

[0371] Embodiment 4: The enhanced recommended bit rate command instruction can indicate per LCH granularity or per DRB granularity or per Qos flow granularity.

[0372] Embodiment 5: The enhanced recommended bit rate command instruction can simultaneously carry information for at least one LCH or DRB or Qos flow.

[0373] Optionally, the first MAC CE can carry multiple information pairs, each of which indicates an LCH ID and a corresponding recommended bit rate, as shown in FIG. 1D.

[0374] Optionally, in order to save the indication overhead of LCH / DRB / Qos flow ID, a bitmap can be used for expression; wherein, the LCH / DRB / Qos flow ID can be arranged in ascending order or descending order according to the index, as shown in FIG. 1E.

[0375] In an example, for the LCH ID, N bits (for example, 32 bits) can be used, wherein the bit position corresponding to the LCH without the function of enabling the enhanced recommended bit rate command instruction is 0; and the bit position corresponding to the LCH with 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.

[0376] In an example, in order to reduce the signaling overhead, only the LCHs enabling the function are indicated in the bitmap, which can be arranged in ascending order or descending order according to the LCH ID index.

[0377] Embodiment 6, for the first MAC CE, add a reserved eLCID to indicate the format of the first MAC CE.

[0378] Embodiment 7, if the first MAC CE multiplexes the second MAC CE format of the original recommended bit rate, the reserved bit therein can be extended for use.

[0379] In an embodiment, the network indicates whether the function of extending the use of the reserved bit in the second MAC CE format of the original recommended bit rate is enabled, i.e., the terminal can only use the reserved bit when the function is enabled.

[0380] Embodiment 8, in order to increase the number of code points of the first table, the reserved bit in the second MAC CE format can be extended or a new bit can be added.

[0381] Optionally, the reserved bit can be a bit of the R field, or a bit of the UL / DL field.

[0382] It should be noted that if the recommended bit rate instruction is only used for downlink, the bit of the UL / DL field can be used as an indication code point.

[0383] Embodiment 9, the reserved bit can be used to indicate whether the recommended bit rate indicated by the MAC CE is determined according to the value of the bit field of the first table or the value of the bit field of the second table.

[0384] In an embodiment, the indication can 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.

[0385] In an embodiment, the indication can be indicated by the bit of the UL / DL field in the MAC CE. If the bit of the UL / DL field is 0, the second table is used; if the bit of the UL / DL field is 1, the first table is used. Alternatively, if the bit of the UL / DL field is 1, the second table is used; if the bit of the UL / DL field is 0, the first table is used.

[0386] Embodiment 10, the network can explicitly indicate the parameters used for LCH / DRB / Qos flow, for example, whether the recommended bit rate is determined according to the first table or the second table. Alternatively, whether the product factor uses the original product factor or the extended product factor.

[0387] In one embodiment, the network can also implicitly indicate the parameters used for 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 product factor is the original product factor or the extended product factor.

[0388] In one embodiment, the existing indication message (e.g., additionalBSR-TableAllowed) can be reused to indicate whether 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 large, at which time the first table needs to be used.

[0389] Based on this, by using this implicit notification, 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 product factor is the original product factor or the extended product factor.

[0390] In one example, if the logical channel is configured to use the extended BSR table, it means that the network indicates that the recommended bit rate is determined according to the first table. Otherwise, the recommended bit rate is determined according to the second table.

[0391] In one embodiment, the network can also implicitly indicate the parameters used for 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 product factor is the original product factor or the extended product factor.

[0392] In one embodiment, the network can also implicitly indicate the parameters used for 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 product factor is the original product factor or the extended product factor.

[0393] The embodiments of the present disclosure also provide a device for implementing any of the above methods. For example, a device is provided, which includes units or modules for implementing the steps performed by the terminal in any of the above methods. For another example, another device is provided, which includes units or modules for implementing the steps performed by the network device (e.g., an access network device, or a core network device, etc.) in any of the above methods.
