By applying this method, the peak data rate can be determined for an eRedCap terminal with degraded capabilities to meet the requirement of further restricted TBS, such that the ratio of the sum of all TBSs of an eRedCap terminal scheduled by a base station within one slot to the duration of this time slot needs to be within the constraint range of this newly determined peak data rate.

Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a method and apparatus for determining peak data rate. Background Art

[0002] The ratio of the sum of the total transport block sizes (TBS) of all transport blocks scheduled by a base station for a terminal within a time slot (slot) to the time length (slot duration) of the time slot needs to be within the constraint range of the peak data rate (or maximum data rate).

[0003] Currently, for reduced capability (eRedCap) terminals, a possible solution with reduced complexity is to limit the TBS. This solution is beneficial for reducing the buffer size of hybrid automatic repeat request (HARQ), and the cost of devices such as low density parity check code (LDPC) encoding. However, if the TBS is further restricted, the peak data rate of traditional terminals as a constraint condition for the TBS will no longer apply.

[0004] However, there is currently a lack of an effective solution for determining the peak data rate for eRedCap terminals. Summary of the Invention

[0042] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, but should not be construed as limiting the present application.

[0044] It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0045] For ease of understanding, the terms involved in this embodiment are introduced first.

[0046] 1. Physical Uplink Shared Channel (PUSCH)

[0047] As the main uplink data bearing channel in the physical layer, PUSCH is used for the scheduled transmission of uplink data and can carry control information, user service information, broadcast service information, etc.

[0048] 2. Physical Downlink Shared Channel (PDSCH)

[0049] PDSCH is used to carry data from the Downlink Shared Channel (DSCH).

[0050] 3. eRedCap terminal

[0051] The 3rd Generation Partnership Project (3GPP) established a dedicated standard project in the communication protocol Release 17 (Rel-17) stage to analyze and optimize the functional characteristics of existing 5G terminals and networks, so as to enable 5G Internet of Things (IoT) terminals to access the 5G core network through the 5G New Radio (NR). In this standard project, 3GPP proposed NR devices supporting Reduced Capability, that is, RedCap terminals. Compared with traditional enhanced mobile broadband (eMBB) devices and ultra-reliable and low latency communication (URLLC) devices, RedCap terminal devices have the advantages of lower cost, lower complexity, more compact size, and sufficient performance. And eRedCap terminals further reduce the terminal cost on the basis of RedCap terminals to support 5G IoT terminals with lower rates to use NR technology.

[0052] Currently, for eRedCap terminals, a possible solution to reduce complexity is to limit the Transport Block Size (TBS). This solution is beneficial to the HARQ buffer size and the reduction of the cost of components such as LDPC coding. If the TBS is further restricted, the peak data rate (or the maximum data rate) of traditional terminals as a constraint condition of the TBS will no longer be applicable.

[0053] Therefore, this embodiment proposes a method and device for determining the peak data rate, providing an effective solution for determining the peak data rate of eRedCap terminals to meet the requirement of further restricting the TBS.

[0054] The following will introduce in detail the method and device for determining the peak data rate provided by this application with reference to the accompanying drawings.

[0055] Figure 1 The flowchart of one method for determining the peak data rate according to an embodiment of this application is shown. It can be applied to the eRedCap terminal side or the base station side. As Figure 1 shown, it may include the following steps.

[0056] Step 101, obtain the maximum uplink TBS supported by the eRedCap terminal, and obtain the maximum downlink TBS supported by the eRedCap terminal.

[0057] The maximum uplink TBS and the maximum downlink TBS supported by the eRedCap terminal can be obtained from the communication protocol. For example, it can be directly specified in the communication protocol that the maximum uplink TBS (transport block size) supported by the eRedCap terminal is U bits (number of bits), and it can be directly specified in the communication protocol that the maximum downlink TBS supported by the eRedCap terminal is D bits. These contents can be preset in the communication protocol.

[0058] Step 102: Determine the peak data rate of the uplink supported by the eRedCap terminal according to the maximum uplink TBS supported by the eRedCap terminal, the duration of a time slot, and the maximum number of uplink TBs supported by the eRedCap terminal in this time slot, and determine the peak data rate of the downlink supported by the eRedCap terminal according to the maximum downlink TBS supported by the eRedCap terminal, the duration of a time slot, and the maximum number of downlink TBs supported by the eRedCap terminal in this time slot.

[0059] For example, according to the maximum uplink TBS (U bits) supported by the eRedCap terminal specified in the communication protocol, the slot duration, and the maximum number of uplink TBs supported by the eRedCap terminal in a slot, calculate the peak data rate of the uplink supported by the eRedCap terminal; and according to the maximum downlink TBS (D bits) supported by the eRedCap terminal specified in the communication protocol, the slot duration, and the maximum number of downlink TBs supported by the eRedCap terminal in the slot, calculate the peak data rate of the downlink supported by the eRedCap terminal.

[0060] By applying the method for determining the peak data rate provided in this embodiment, the peak data rate of the uplink supported by the eRedCap terminal can be determined according to the maximum uplink TBS supported by the eRedCap terminal specified in the communication protocol, the duration of a time slot, and the maximum number of uplink TBs supported by the eRedCap terminal in this time slot, and the peak data rate of the downlink supported by the eRedCap terminal can be determined according to the maximum downlink TBS supported by the eRedCap terminal specified in the communication protocol, the duration of a time slot, and the maximum number of downlink TBs supported by the eRedCap terminal in this time slot. Furthermore, the peak data rate can be determined for the eRedCap terminal to meet the requirement of further restricted TBS.

[0061] Figure 2 shows a schematic flowchart of one method for determining the peak data rate according to an embodiment of the present application. Based onFigure 1 The illustrated embodiment, such as Figure 2 shown, can be applied to the eRedCap terminal side or the base station side, and the method may include the following steps.

[0062] Step 201: Obtain the maximum uplink TBS supported by the eRedCap terminal and obtain the maximum downlink TBS supported by the eRedCap terminal.

[0063] Step 202: Multiply the maximum uplink TBS supported by the eRedCap terminal by the maximum number of uplink TBs supported by the eRedCap terminal in one time slot, and then divide by the duration of the time slot to obtain the peak data rate of the uplink supported by the eRedCap terminal, and multiply the maximum downlink TBS supported by the eRedCap terminal by the maximum number of downlink TBs supported by the eRedCap terminal in one time slot, and then divide by the duration of the time slot to obtain the peak data rate of the downlink supported by the eRedCap terminal.

[0064] For example, to determine the peak data rate of the uplink supported by the eRedCap terminal in TS38.306 protocol, as shown in the following formula (1):

[0065] Peak data rate of the uplink supported by the eRedCap terminal = U * M1 / T_slot (Formula 1)

[0066] In Formula 1, U is the maximum uplink TBS supported by the eRedCap terminal, M1 is the maximum number of uplink TBs that can be transmitted or supported by the eRedCap terminal in one slot, and T_slot is the duration of the slot.

[0067] To determine the peak data rate of the downlink supported by the eRedCap terminal in TS38.306 protocol, as shown in the following formula (2):

[0068] Peak data rate of the downlink supported by the eRedCap terminal = D * M2 / T_slot (Formula 2)

[0069] In Formula 2, D is the maximum downlink TBS supported by the eRedCap terminal, M2 is the maximum number of downlink TBs that can be transmitted or supported by the eRedCap terminal in one slot, and T_slot is the duration of the slot.

[0070] By applying the method for determining the peak data rate provided in this embodiment, the maximum uplink transport block size (TBS) supported by the eRedCap terminal specified in the communication protocol can be multiplied by the maximum number of uplink transport blocks (TBs) supported by the eRedCap terminal within one time slot, and then divided by the duration of this time slot to obtain the peak data rate of the uplink supported by the eRedCap terminal. Also, the maximum downlink TBS supported by the eRedCap terminal specified in the communication protocol can be multiplied by the maximum number of downlink TBs supported by the eRedCap terminal within one time slot, and then divided by the duration of this time slot to obtain the peak data rate of the downlink supported by the eRedCap terminal. Furthermore, the peak data rate can be determined for the eRedCap terminal to meet the requirement of further restricted TBS.

[0071] Figure 3 Fig. 4 shows a flowchart of one method for determining the peak data rate according to an embodiment of the present application. Based on Figure 1 the embodiment shown, as Figure 3 shown, it can be applied to the eRedCap terminal side or the base station side, and this method may include the following steps.

[0072] Step 301, obtain the maximum uplink TBS supported by the eRedCap terminal and obtain the maximum downlink TBS supported by the eRedCap terminal.

[0073] After obtaining the maximum uplink TBS supported by the eRedCap terminal and the maximum downlink TBS supported by the eRedCap terminal, this embodiment may further include: if the uplink TBS determined according to the scheduling information of the downlink control information (DCI) of the eRedCap terminal is greater than the maximum uplink TBS supported by the eRedCap terminal specified in the communication protocol, then restrict the eRedCap terminal from processing this physical uplink shared channel (PUSCH) or not processing all PUSCHs within the time slot; or, restrict the base station from performing the corresponding scheduling; if the downlink TBS determined according to the scheduling information of the DCI of the eRedCap terminal is greater than the maximum downlink TBS supported by the eRedCap terminal specified in the communication protocol, then restrict the eRedCap terminal from processing this physical downlink shared channel (PDSCH) or not processing all PDSCHs within the time slot; or, restrict the base station from performing the corresponding scheduling. By this optional method, the normal operation of the communication service of the eRedCap terminal can be ensured.

[0074] For example, on the eRedCap terminal side, if the uplink TBS determined by the eRedCap terminal according to the DCI scheduling information is greater than U bits (the maximum uplink TBS supported by the eRedCap terminal specified in the communication protocol), the processing of this PUSCH is not performed, or the processing of all PUSCHs within this slot is not performed. Or on the base station side, if the uplink TBS determined according to the DCI scheduling information is greater than U bits, the base station is restricted from performing this scheduling.

[0075] For another example, on the eRedCap terminal side, if the downlink TBS determined by the eRedCap terminal according to the DCI scheduling information is greater than D bits (the maximum downlink TBS supported by the eRedCap terminal specified in the communication protocol), the processing of this PDSCH is not performed, or the processing of all PDSCHs within this slot is not performed. Or on the base station side, if the downlink TBS determined according to the DCI scheduling information is greater than D bits, the base station is restricted from performing this scheduling.

[0076] Step 302: Determine the peak data rate supported by the eRedCap terminal for the uplink based on the maximum uplink TBS supported by the eRedCap terminal, the duration of a time slot, and the maximum number of uplink TBs supported by the eRedCap terminal within this time slot, and determine the peak data rate supported by the eRedCap terminal for the downlink based on the maximum downlink TBS supported by the eRedCap terminal, the duration of a time slot, and the maximum number of downlink TBs supported by the eRedCap terminal within this time slot.

[0077] Step 303: If the uplink data rate determined according to Formula 3 is greater than the peak data rate supported by the eRedCap terminal for the uplink, restrict the eRedCap terminal from processing the PUSCH within the time slot, or restrict the base station from performing the corresponding scheduling; if the downlink data rate determined according to Formula 4 is greater than the peak data rate supported by the eRedCap terminal for the downlink, restrict the eRedCap terminal from processing the PDSCH within the time slot, or restrict the base station from performing the corresponding scheduling.

[0078] Among them, Formula 3 is as follows:

[0079]

[0080] In Formula 3, M' is the number of TBs for uplink transmission within the time slot, m' is the m-th TB for uplink transmission, V m' is the TBS of the m-th TB for uplink transmission, and T slot is the duration of the time slot.

[0081] Formula 4 is as follows:

[0082]

[0083] In Formula 4, M" is the number of TBs for downlink transmission within a time slot, m" is the m-th TB for downlink transmission, V m" is the TBS of the m-th TB for downlink transmission, and T slot is the duration of the time slot.

[0084] For example, on the eRedCap terminal side, if the uplink data rate determined by the eRedCap terminal according to Formula 3 is greater than the peak uplink data rate supported by the eRedCap terminal calculated in step 302, then the PUSCH within this slot is not processed; or on the base station side, if the uplink data rate determined according to Formula 3 is greater than the peak uplink data rate supported by the eRedCap terminal calculated in step 302, then the base station is restricted from performing this scheduling. Furthermore, it is possible to accurately limit the maximum uplink TBS supported by the eRedCap terminal according to the peak uplink data rate supported by the eRedCap terminal.

[0085] For another example, on the eRedCap terminal side, if the downlink data rate determined by the eRedCap terminal according to Formula 4 is greater than the peak downlink data rate supported by the eRedCap terminal calculated in step 302, then the PDSCH within this slot is not processed; or on the base station side, if the downlink data rate determined according to Formula 4 is greater than the peak downlink data rate supported by the eRedCap terminal calculated in step 302, then the base station is restricted from performing this scheduling. Furthermore, it is possible to accurately limit the maximum downlink TBS supported by the eRedCap terminal according to the peak downlink data rate supported by the eRedCap terminal.

[0086] It should be noted that although Figure 3 the illustrated embodiment is described based on Figure 1 the illustrated embodiment, similarly, this Figure 3 illustrated embodiment can also be based on Figure 2 the illustrated embodiment, and will not be elaborated here.

[0087] By applying the method provided in this embodiment, the peak data rate can be determined for the eRedCap terminal to meet the requirement that the TBS is further restricted. If the uplink TBS determined according to the scheduling information of the eRedCap terminal DCI is greater than the maximum uplink TBS supported by the eRedCap terminal specified in the communication protocol, the eRedCap terminal is restricted from processing the PUSCH or from processing all PUSCHs within a time slot; alternatively, the base station is restricted from performing the corresponding scheduling. If the downlink TBS determined according to the scheduling information of the eRedCap terminal DCI is greater than the maximum downlink TBS supported by the eRedCap terminal specified in the communication protocol, the eRedCap terminal is restricted from processing the PDSCH or from processing all PDSCHs within a time slot; alternatively, the base station is restricted from performing the corresponding scheduling. And it can be realized to accurately restrict the maximum uplink TBS supported by the eRedCap terminal according to the peak data rate supported by the uplink of the eRedCap terminal and to accurately restrict the maximum downlink TBS supported by the eRedCap terminal according to the peak data rate supported by the downlink of the eRedCap terminal, so as to ensure the normal operation of the communication services of the eRedCap terminal.

[0088] Figure 4 FIG. is a schematic flowchart of a method for determining a peak data rate according to an embodiment of the present application. As Figure 4 shown, it can be applied to the eRedCap terminal side or the base station side, and the method may include the following steps.

[0089] Step 401, obtain a first scaling factor of the PUSCH channel and a second scaling factor of the PDSCH channel.

[0090] Among them, both the first scaling factor and the second scaling factor are greater than 0 and less than 1. The first scaling factor and the second scaling factor can be obtained through the communication protocol or determined by the terminal itself and reported to the base station. Optionally, the maximum uplink TBS supported by the eRedCap terminal specified in the communication protocol is the maximum uplink TBS supported by the traditional terminal multiplied by the first scaling factor, and the maximum downlink TBS supported by the eRedCap terminal is the maximum downlink TBS supported by the traditional terminal multiplied by the second scaling factor.

[0091] For example, it can be stipulated in the communication protocol that the maximum uplink TBS supported by the eRedCap terminal is the maximum uplink TBS supported by the traditional terminal multiplied by a first scaling factor, and the first scaling factor can be 1 / A1, where A1>1; and it can be stipulated in the communication protocol that the maximum downlink TBS supported by the eRedCap terminal is the maximum downlink TBS supported by the traditional terminal multiplied by a second scaling factor, and the second scaling factor can be 1 / A2, where A2>1. Through this stipulated content, the first scaling factor 1 / A1 of the PUSCH and the second scaling factor 1 / A2 of the PDSCH can be obtained. Among them, the PDSCH channel and the PUSCH channel can have different scaling factors, that is, 1 / A1 and 1 / A2 can be different.

[0092] Step 402: Determine the peak data rate of the uplink supported by the eRedCap terminal according to the peak data rate of the uplink supported by the traditional terminal and the first scaling factor of the PUSCH channel, and determine the peak data rate of the downlink supported by the eRedCap terminal according to the peak data rate of the downlink supported by the traditional terminal and the second scaling factor of the PDSCH channel.

[0093] For example, according to the peak data rate of the uplink supported by the traditional terminal (different from the eRedCap terminal) and the first scaling factor 1 / A1 (A1>1) of the PUSCH channel, determine the peak data rate of the uplink supported by the eRedCap terminal, and according to the peak data rate of the downlink supported by the traditional terminal and the second scaling factor 1 / A2 (A2>1) of the PDSCH channel, determine the peak data rate of the downlink supported by the eRedCap terminal.

[0094] By applying the method for determining the peak data rate provided in this embodiment, the peak data rate of the uplink supported by the eRedCap terminal can be determined according to the peak data rate of the uplink supported by the traditional terminal and the first scaling factor of the PUSCH channel, and the peak data rate of the downlink supported by the eRedCap terminal can be determined according to the peak data rate of the downlink supported by the traditional terminal and the second scaling factor of the PDSCH channel. Furthermore, the peak data rate can be determined for the eRedCap terminal to meet the requirement that the TBS is further restricted.

[0095] Figure 5 It is a schematic flowchart of a method for determining a peak data rate according to an embodiment of the present application. Based on Figure 4 the embodiments shown, as Figure 5 shown, it can be applied to the eRedCap terminal side or the base station side, and can include the following steps.

[0096] Step 501: Obtain the first scaling factor of the PUSCH channel and the second scaling factor of the PDSCH channel.

[0097] Both the first scaling factor and the second scaling factor are greater than 0 and less than 1.

[0098] Step 502: Multiply the peak data rate of the uplink supported by a legacy terminal by the first scaling factor of the PUSCH channel to obtain the peak data rate of the uplink supported by the eRedCap terminal, and multiply the peak data rate of the downlink supported by the legacy terminal by the second scaling factor of the PDSCH channel to obtain the peak data rate of the downlink supported by the eRedCap terminal.

[0099] For example, multiply the peak data rate (peak data rate) of the uplink supported by a legacy terminal by the first scaling factor 1 / A1 (A1 > 1) of the PUSCH channel to obtain the peak data rate of the uplink supported by the eRedCap terminal, and multiply the peak data rate of the downlink supported by the legacy terminal by the second scaling factor 1 / A2 (A2 > 1) of the PDSCH channel to obtain the peak data rate of the downlink supported by the eRedCap terminal.

[0100] By applying the method provided in this embodiment, the peak data rate of the uplink supported by a legacy terminal can be multiplied by the first scaling factor of the PUSCH channel to obtain the peak data rate of the uplink supported by the eRedCap terminal, and the peak data rate of the downlink supported by the legacy terminal can be multiplied by the second scaling factor of the PDSCH channel to obtain the peak data rate of the downlink supported by the eRedCap terminal. Furthermore, the peak data rate can be determined for the eRedCap terminal to meet the requirement of further restricted TBS.

[0101] Figure 6 shows a schematic flowchart of a method for determining one of the peak data rates according to an embodiment of the present application. Based on Figure 4 the shown embodiment, as Figure 6 shown, it can be applied to the eRedCap terminal side or the base station side, and the method may include the following steps.

[0102] Step 601: Obtain the first scaling factor of the PUSCH channel and the second scaling factor of the PDSCH channel.

[0103] Both the first scaling factor and the second scaling factor can be greater than 0 and less than 1.

[0104] Step 602: Determine the peak uplink data rate supported by the eRedCap terminal based on the peak uplink data rate supported by the traditional terminal and the first scaling factor of the PUSCH channel, and determine the peak downlink data rate supported by the eRedCap terminal based on the peak downlink data rate supported by the traditional terminal and the second scaling factor of the PDSCH channel.

[0105] Step 603: If the uplink data rate determined according to Formula 3 is greater than the peak uplink data rate supported by the eRedCap terminal, then restrict the eRedCap terminal from processing the PUSCH within the time slot, or restrict the base station from performing the corresponding scheduling; if the downlink data rate determined according to Formula 4 is greater than the peak downlink data rate supported by the eRedCap terminal, then restrict the eRedCap terminal from processing the PDSCH within the time slot, or restrict the base station from performing the corresponding scheduling.

[0106] It should be noted that the content of Formula 3 and Formula 4 used in Step 603 can refer to the content of Formula 3 and Formula 4 in the above Step 303, which will not be elaborated here.

[0107] For example, in the eRedCap terminal, if the uplink data rate determined by the eRedCap terminal according to Formula 3 is greater than the peak uplink data rate supported by the eRedCap terminal calculated in Step 602, then the eRedCap terminal does not process the PUSCH within this slot. Or on the base station side, if the uplink data rate determined according to Formula 3 is greater than the peak uplink data rate supported by the eRedCap terminal calculated in Step 602, then the base station is restricted from performing this scheduling. Thus, the maximum uplink TBS supported by the eRedCap terminal can be accurately restricted according to the peak uplink data rate supported by the eRedCap terminal.

[0108] For another example, in the eRedCap terminal, if the downlink data rate determined by the eRedCap terminal according to Formula 4 is greater than the peak downlink data rate supported by the eRedCap terminal calculated in Step 602, then the eRedCap terminal does not process the PDSCH within this slot. Or on the base station side, if the downlink data rate determined according to Formula 4 is greater than the peak downlink data rate supported by the eRedCap terminal calculated in Step 602, then the base station is restricted from performing this scheduling. Thus, the maximum downlink TBS supported by the eRedCap terminal can be accurately restricted according to the peak downlink data rate supported by the eRedCap terminal.

[0109] It should be noted that although Figure 6 the illustrated embodiment is described based on Figure 4 the illustrated embodiment, similarly, thisFigure 6 The illustrated embodiments may also be based on Figure 5 the illustrated embodiments, which will not be elaborated herein.

[0110] By applying the method provided in this embodiment, the peak data rate can be determined for the eRedCap terminal to meet the requirement of further restricted TBS. And it can be realized to accurately limit the maximum uplink TBS supported by the eRedCap terminal according to the peak data rate supported by the uplink of the eRedCap terminal, and accurately limit the maximum downlink TBS supported by the eRedCap terminal according to the peak data rate supported by the downlink of the eRedCap terminal, so as to ensure the normal operation of the communication service of the eRedCap terminal.

[0111] Figure 7 The flowchart of one method for determining the peak data rate according to an embodiment of the present application is shown. As Figure 7 shown, it can be applied to the eRedCap terminal side or the base station side, and may include the following steps.

[0112] Step 701, obtain the peak data rate supported by the uplink of the eRedCap terminal specified in the communication protocol as the peak data rate supported by the uplink of the eRedCap terminal, and obtain the peak data rate supported by the downlink of the eRedCap terminal specified in the communication protocol as the peak data rate supported by the downlink of the eRedCap terminal.

[0113] For example, the specific value of the peak data rate of the eRedCap terminal can be directly specified in the communication protocol, and different values can be set for the uplink and downlink. Furthermore, the peak data rate supported by the uplink of the eRedCap terminal specified in the communication protocol can be obtained as the peak data rate supported by the uplink of the eRedCap terminal, and the peak data rate supported by the downlink of the eRedCap terminal specified in the communication protocol can be obtained as the peak data rate supported by the downlink of the eRedCap terminal.

[0114] By applying the method for determining the peak data rate provided in this embodiment, the peak data rate supported by the uplink of the eRedCap terminal specified in the communication protocol can be obtained as the peak data rate supported by the uplink of the eRedCap terminal, and the peak data rate supported by the downlink of the eRedCap terminal specified in the communication protocol can be obtained as the peak data rate supported by the downlink of the eRedCap terminal. Furthermore, the peak data rate can be determined for the eRedCap terminal to meet the requirement of further restricted TBS.

[0115] Figure 8 The flowchart shows one of the methods for determining the peak data rate according to an embodiment of the present application. Based on Figure 7 the shown embodiment, as Figure 8 shown, it can be applied to the eRedCap terminal side or the base station side. The method may include the following steps.

[0116] Step 801: Obtain the peak uplink data rate supported by the eRedCap terminal specified in the communication protocol as the peak uplink data rate supported by the eRedCap terminal, and obtain the peak downlink data rate supported by the eRedCap terminal specified in the communication protocol as the peak downlink data rate supported by the eRedCap terminal.

[0117] Step 802: If the uplink data rate determined according to Formula 3 is greater than the peak uplink data rate supported by the eRedCap terminal, then restrict the eRedCap terminal from processing PUSCH within the time slot, or restrict the base station from performing corresponding scheduling; if the downlink data rate determined according to Formula 4 is greater than the peak downlink data rate supported by the eRedCap terminal, then restrict the eRedCap terminal from processing PDSCH within the time slot, or restrict the base station from performing corresponding scheduling.

[0118] It should be noted that for Formula 3 and Formula 4 used in Step 802, refer to the content shown in Formula 3 and Formula 4 in the above Step 303, which will not be elaborated here.

[0119] For example, on the eRedCap terminal side, if the uplink data rate determined by the eRedCap terminal according to Formula 3 is greater than the peak uplink data rate supported by the eRedCap terminal calculated in Step 801, then the eRedCap terminal does not process PUSCH within this slot. Or on the base station side, if the uplink data rate determined according to Formula 3 is greater than the peak uplink data rate supported by the eRedCap terminal calculated in Step 801, then the base station is restricted from performing this scheduling. Thus, it is possible to accurately limit the maximum uplink TBS supported by the eRedCap terminal according to the peak uplink data rate supported by the eRedCap terminal.

[0120] For another example, on the eRedCap terminal side, if the downlink data rate determined by the eRedCap terminal according to Formula 4 is greater than the peak data rate of the downlink supported by the eRedCap terminal calculated in step 801, the processing of PDSCH within this slot is not performed. Or on the base station side, if the downlink data rate determined by Formula 4 is greater than the peak data rate of the downlink supported by the eRedCap terminal calculated in step 801, the base station is restricted from performing this scheduling. Furthermore, it is possible to accurately limit the maximum downlink TBS supported by the eRedCap terminal according to the peak data rate of the downlink supported by the eRedCap terminal.

[0121] By applying the method for determining the peak data rate provided in this embodiment, the peak data rate can be determined for the eRedCap terminal to meet the requirement of further restricting the TBS. And it is possible to accurately limit the maximum uplink TBS supported by the eRedCap terminal according to the peak data rate of the uplink supported by the eRedCap terminal and accurately limit the maximum downlink TBS supported by the eRedCap terminal according to the peak data rate of the downlink supported by the eRedCap terminal, thereby ensuring the normal operation of the communication services of the eRedCap terminal.

[0122] The above-mentioned Figures 1 to 3 The method shown determines the peak data rate of the uplink supported by the eRedCap terminal based on the maximum uplink TBS supported by the eRedCap terminal, the duration of the time slot, and the maximum number of uplink TBs supported by the eRedCap terminal within the time slot, and can determine the peak data rate of the downlink supported by the eRedCap terminal based on the maximum downlink TBS supported by the eRedCap terminal, the duration of the time slot, and the maximum number of downlink TBs supported by the eRedCap terminal within the time slot. The above-mentioned Figures 4 to 6 The method shown determines the peak data rate of the uplink supported by the eRedCap terminal based on the peak data rate of the uplink supported by the traditional terminal and the first scaling factor 1 / A1 (A1>1) of the PUSCH channel, and determines the peak data rate of the downlink supported by the eRedCap terminal based on the peak data rate of the downlink supported by the traditional terminal and the second scaling factor 1 / A2 (A2>1) of the PDSCH channel. And the above-mentioned Figures 7 to 8 The method shown obtains the peak data rate of the uplink supported by the eRedCap terminal specified in the communication protocol as the peak data rate of the uplink supported by the eRedCap terminal, and obtains the peak data rate of the downlink supported by the eRedCap terminal specified in the communication protocol as the peak data rate of the downlink supported by the eRedCap terminal.

[0123] It should be noted that the above several methods can be comprehensively analyzed according to actual requirements in actual use, so as to determine the peak data rate of the eRedCap terminal. For example, their respective corresponding priorities can be pre-configured, and then according to the priorities, the determination method with the highest priority is selected to obtain the peak data rate of the eRedCap terminal; for another example, the results obtained by these several determination methods can also be weighted and averaged through a weighted average calculation method, so as to determine the peak data rate of the eRedCap terminal, etc.
