图2a示出的初始接入过程与图2b示出的初始接入过程的区别在于：图2a示出的初始接入过程中，步骤S203a为终端设备向网络设备发送RRC连接建立请求消息，说明图2a示出的初始接入过程中终端设备首次与网络设备建立RRC连接，或者在图2a示出的初始接入过程之前终端设备与网络设备建立的RRC连接被释放。图2b示出的初始接入过程中，步骤S203b为终端设备向网络设备发送RRC连接恢复请求消息，这时，说明终端设备在上一次与网络设备建立RRC连接之后，当网络设备判断出终端设备不需要传输数据时，网络设备将终端设备挂起(Suspend)，即网络设备释放与终端设备的RRC连接，但是网络设备保存终端设备的上下文信息，并且终端设备保存网络设备配置给当前终端设备的RRC配置信息；当终端设备需要传输数据时，终端设备向网络设备发送RRC连接恢复请求消息，进而使得网络设备为终端设备恢复RRC连接。图2b相比于图2a示出的初始接入过程，图2b示出的初始接入过程减少了网络设备与终端设备建立RRC连接的时间开销、以及信令开销。The initial access procedure shown in FIG. 2a is different from the initial access procedure shown in FIG. 2b in that, in the initial access procedure shown in FIG. 2a, step S203a sends an RRC connection setup request message to the network device for the terminal device, saying In the initial access procedure shown in FIG. 2a, the terminal device establishes an RRC connection with the network device for the first time, or the RRC connection established by the terminal device with the network device is released before the initial access procedure shown in FIG. 2a. In the initial access process shown in FIG. 2b, step S203b sends an RRC connection recovery request message to the network device for the terminal device. In this case, after the terminal device establishes an RRC connection with the network device, the network device determines the terminal device. When the data is not required to be transmitted, the network device suspends the terminal device (Suspend), that is, the network device releases the RRC connection with the terminal device, but the network device saves the context information of the terminal device, and the terminal device saves the network device configuration to the current terminal device. RRC configuration information; when the terminal device needs to transmit data, the terminal device sends an RRC connection recovery request message to the network device, so that the network device restores the RRC connection for the terminal device. 2b Compared to the initial access procedure illustrated in FIG. 2a, the initial access procedure illustrated in FIG. 2b reduces the time overhead and signaling overhead for the network device to establish an RRC connection with the terminal device.

需要说明的是，上述初始接入过程中终端设备与网络设备交互的第三条消息为It should be noted that the third message that the terminal device interacts with the network device in the initial access process is

RRC连接建立请求消息或RRC连接恢复请求消息，但随着***的演进，初始接入过程中终端设备与网络设备交互的第三条消息可能为其他消息，此时仍适用于本申请实施例提供的技术方案。The RRC connection setup request message or the RRC connection recovery request message, but the third message that the terminal device interacts with the network device in the initial access process may be other messages, which is still applicable to the embodiment of the present application.

图15为本申请实施例提供的再一种确定传输块大小的方法流程示意图。如图15所示，该方法包括：FIG. 15 is a schematic flowchart of still another method for determining a transport block size according to an embodiment of the present application. As shown in Figure 15, the method includes:

401、终端设备接收网络设备发送的随机接入响应，随机接入响应中包括资源分配字段和指示第一索引的字段，第一索引是第一传输块大小索引或者第一调制编码方式索引。401. The terminal device receives a random access response sent by the network device, where the random access response includes a resource allocation field and a field indicating a first index, where the first index is a first transport block size index or a first modulation and coding mode index.

402、终端设备采用第一查询方式，根据资源分配字段和指示第一索引的字段，确定上行信息的传输块大小。402. The terminal device adopts a first query manner, and determines a transport block size of the uplink information according to the resource allocation field and a field indicating the first index.

其中，步骤402，具体包括：Wherein, step 402 specifically includes:

4021、终端设备根据指示第一索引的字段，确定第一索引；4041. The terminal device determines, according to a field indicating the first index, a first index.

4022、终端设备根据第一索引，确定第二索引，其中，第二索引是第二传输块大小索引或者第二调制编码方式索引，第二索引大于或者等于第一索引；4042: The terminal device determines, according to the first index, a second index, where the second index is a second transport block size index or a second modulation and coding mode index, where the second index is greater than or equal to the first index;

4023a、终端设备将与资源分配字段和第二索引对应的传输块大小，确定为上行信息的传输块大小。 4023a. The terminal device determines a transport block size corresponding to the resource allocation field and the second index as a transport block size of the uplink information.

在可选的是一种实施方式中，步骤4023a，具体包括：In an optional implementation, the step 4023a specifically includes:

4023、终端设备根据资源分配字段和第二索引，在传输块大小表格中查询与资源分配字段和第二索引对应的传输块大小；4023. The terminal device queries, according to the resource allocation field and the second index, a transport block size corresponding to the resource allocation field and the second index in the transport block size table.

4024、终端设备确定查询到的传输块大小，为上行信息的传输块大小。4024. The terminal device determines the size of the transport block that is queried, and is the transport block size of the uplink information.

具体来说，首先，终端设备接收到随机接入响应之后，终端设备根据指示第一索引的字段，确定该指示第一索引的字段所指示的第一索引。Specifically, after the terminal device receives the random access response, the terminal device determines, according to the field indicating the first index, the first index indicated by the field indicating the first index.

然后，终端设备根据第一索引，确定第二索引，其中，确定出的第二索引大于等于第一索引的。其中，第一索引为第一TBS索引，则第二索引为第二TBS索引；第一索引为第一MCS索引，则第二索引为第二MCS索引。Then, the terminal device determines, according to the first index, a second index, where the determined second index is greater than or equal to the first index. The first index is the first TBS index, and the second index is the second TBS index; the first index is the first MCS index, and the second index is the second MCS index.

在一种可选的实施方式中，终端设备可以根据索引映射关系，确定与第一索引对应的第二索引，其中，索引映射关系包括与第一索引分别一一对应的第二索引，且每一个第一索引小于等于与该第一索引对应的第二索引。本申请中采用的索引映射关系中第二索引的取值，不做限定。In an optional implementation manner, the terminal device may determine, according to the index mapping relationship, a second index corresponding to the first index, where the index mapping relationship includes a second index corresponding to the first index, and each A first index is less than or equal to a second index corresponding to the first index. The value of the second index in the index mapping relationship used in this application is not limited.

在另一种可选的实施方式中，终端设备将第一索引加上一个预设值shift，得到第二索引；即，第二MCS索引＝第一MCS索引+shift，第二TBS索引＝第一TBS索引+shift。例如，若shift＝8，第一MCS索引＝0～7，新的解读方法范围为第二MCS索引＝8～15，此时对应的TBS索引取值为8～14；若shift＝6,第一TBS索引＝0～3，新的解读方法范围为第二TBS索引＝6～9。In another optional implementation manner, the terminal device adds a preset value shift to the first index to obtain a second index; that is, the second MCS index=the first MCS index+shift, and the second TBS index=the second A TBS index + shift. For example, if shift=8, the first MCS index is 0 to 7, the new interpretation method ranges from the second MCS index=8 to 15, and the corresponding TBS index is 8 to 14; if shift=6, the first A TBS index = 0 to 3, and the new interpretation method ranges from the second TBS index = 6 to 9.

然后，终端设备根据资源分配字段指示的资源指示值，确定第一物理资源数；这里，确定第一物理资源数的方法可以采用图8的步骤102中的确定第一物理资源数的方法。接着，根据第一物理资源数和第二索引，在传输块大小表格中查询与第一物理资源数和第二索引对应的TBSize。进而，终端设备可以将查询到的传输块大小，作为上行信息的传输块大小。并且，在查询到的传输块大小小于等于预设比特值时，终端设备确定查询到的传输块大小为上行信息的传输块大小；在查询到的传输块大小大于预设比特值时，终端设备确定预设比特值为上行信息的传输块大小；或者，在查询到的传输块大小大于预设比特值时，终端设备将TBS索引进行回退，直至查找到一个小于等于预设比特值的传输块大小，并将该传输块大小作为上行信息的传输块大小，同时，这种情况下，终端设备保持查表所用的物理资源数不变。在可选的一种实施方式中，预设比特值为1000比特。Then, the terminal device determines the first physical resource number according to the resource indication value indicated by the resource allocation field. Here, the method for determining the first physical resource number may adopt the method for determining the first physical resource number in step 102 of FIG. 8 . Then, according to the first physical resource number and the second index, the TBSize corresponding to the first physical resource number and the second index is queried in the transport block size table. Furthermore, the terminal device can use the queried transport block size as the transport block size of the uplink information. And, when the queried transport block size is less than or equal to the preset bit value, the terminal device determines that the queried transport block size is the transport block size of the uplink information; and when the queried transport block size is greater than the preset bit value, the terminal device Determining that the preset bit value is a transport block size of the uplink information; or, when the queried transport block size is greater than the preset bit value, the terminal device rewinds the TBS index until a transmission less than or equal to the preset bit value is found. The block size is used as the transport block size of the uplink information, and in this case, the number of physical resources used by the terminal device to keep the table lookup does not change. In an optional embodiment, the preset bit value is 1000 bits.

举例来说，针对于CE ModeA的终端设备，资源分配字段所指示的第一物理资源数的个数可以为1、2、3、6，第一MCS索引＝0～7，终端设备将第一索引加上一个预设值shift＝8，终端设备可以确定第二MCS索引＝8～15，此时对应的TBS取值为8～14。然后，终端设备可以在TBS表格中确定出的TBSize的范围如表12所示，此时，终端设备采用第一物理资源数的个数取值为1、2、3、6，TBS索引取值为8～14进行查表，对应的TBSize的数据最大为1736比特。但是由于CE ModeA的终端设备限制了上行信息的最大TBSize不可以超过预设比特值，例如该预设比特值为1000比特，进而此时确定TBSize的数据最大为936比特。For example, for the terminal device of the CE ModeA, the number of the first physical resources indicated by the resource allocation field may be 1, 2, 3, and 6, the first MCS index is 0 to 7, and the terminal device will be the first. The index adds a preset value of shift=8, and the terminal device can determine that the second MCS index is 8 to 15, and the corresponding TBS value is 8 to 14. Then, the range of the TBSize that the terminal device can determine in the TBS table is as shown in Table 12. In this case, the number of the first physical resource used by the terminal device is 1, 2, 3, and 6, and the TBS index is used. Look up the table for 8~14, The corresponding TBSize data is up to 1736 bits. However, since the terminal device of the CE ModeA limits the maximum TBSize of the uplink information to not exceed the preset bit value, for example, the preset bit value is 1000 bits, and thus the data of the TBSize is determined to be at most 936 bits.

表12步骤402针对CE ModeA的终端设备确定的TBSize的范围Step 12 of Table 12 determines the range of TBSize for the terminal device of CE ModeA.

又举例来说，针对于CE ModeB的终端设备，资源分配字段所指示的第一物理资源数的个数可以为3、6，第一TBS索引＝0～3，终端设备将第一索引加上一个预设值shift＝6，终端设备可以确定第二TBS索引＝6～9。然后，终端设备可以在TBS表格中确定出的TBSize的范围如表13所示，此时，终端设备采用第一物理资源数的个数取值为3、6，TBS索引取值为6～9进行查表，对应的TBSize的数据最大为936比特。并且，CE ModeB的终端设备可以限制了上行信息的最大TBSize不可以超过预设比特值，例如该预设比特值为1000比特。For example, for the terminal device of the CE ModeB, the number of the first physical resources indicated by the resource allocation field may be 3 or 6, and the first TBS index is 0 to 3, and the terminal device adds the first index. A preset value shift=6, the terminal device can determine the second TBS index=6-9. Then, the range of the TBSize that the terminal device can determine in the TBS table is as shown in Table 13. In this case, the number of the first physical resource number of the terminal device is 3, 6, and the TBS index is 6-9. For table lookup, the corresponding TBSize data is up to 936 bits. Moreover, the terminal device of the CE ModeB can limit the maximum TBSize of the uplink information to not exceed the preset bit value, for example, the preset bit value is 1000 bits.

501、终端设备接收网络设备发送的随机接入响应，随机接入响应中包括资源分配字段和指示第一索引的字段，第一索引是第一传输块大小索引或者第一调制编码方式索引。501. The terminal device receives a random access response sent by the network device, where the random access response includes a resource allocation field and a field indicating a first index, where the first index is a first transport block size index or a first modulation and coding mode index.

在可选的是一种实施方式中，随机接入响应中还包括：类型指示字段；类型指示字段用于指示终端设备是否采用第一查询方式确定上行信息的传输块大小。 In an optional implementation manner, the random access response further includes: a type indication field, where the type indication field is used to indicate whether the terminal device determines the transport block size of the uplink information by using the first query manner.

其中，步骤502，具体包括：Wherein, step 502 specifically includes:

5021、终端设备根据指示第一索引的字段，确定第二索引，其中，第二索引是第二传输块大小索引或者第二调制编码方式索引，第二索引大于或者等于第一索引；The second index is determined according to the field indicating the first index, where the second index is a second transport block size index or a second modulation and coding mode index, and the second index is greater than or equal to the first index.

在可选的是一种实施方式中，步骤5022a，包括：In an optional embodiment, step 5022a includes:

5022、终端设备根据资源分配字段和第二索引，在传输块大小表格中查询与资源分配字段和第二索引对应的传输块大小；5022. The terminal device queries, according to the resource allocation field and the second index, a transport block size corresponding to the resource allocation field and the second index in the transport block size table.

5023、终端设备确定查询到的传输块大小，为上行信息的传输块大小。5023. The terminal device determines the size of the transport block that is queried, and is the transport block size of the uplink information.

具体来说，首先，终端设备根据指示第一索引的字段，确定出第二索引，并且第二索引大于或者等于指示第一索引的字段所指示出的第一索引。其中，第一索引为第一TBS索引，则第二索引为第二TBS索引；第一索引为第一MCS索引，则第二索引为第二MCS索引。Specifically, first, the terminal device determines the second index according to the field indicating the first index, and the second index is greater than or equal to the first index indicated by the field indicating the first index. The first index is the first TBS index, and the second index is the second TBS index; the first index is the first MCS index, and the second index is the second MCS index.

在一种可选的实施方式中，终端设备根据UL grant中的预留比特位，确定指示第一索引的字段指示的状态。例如，现有的指示MCS索引的字段包含3比特，为b₂b₁b₀，预留比特为R，结合后的得到的字段为Rb₂b₁b₀，当UL grant中的R置为1时，Rb₂b₁b₀指示的状态为1000～1111，对应的MCS的索引为8～17共8种状态。又例如，现有的指示MCS索引的字段包含3比特，为b₂b₁b₀，预留比特为R₁和R₀，结合后的得到的字段为R₁R₀b₂b₁b₀；当UL grant中的R置为1时，R₁R₀b₂b₁b₀指示的状态为01000～11111，对应的MCS的索引为8～31。再例如，CE ModeB时，现有的指示TBS索引的字段包含2比特，为b₁b₀，预留比特为R，结合后的得到的字段为Rb₁b₀；当UL grant中的R置为1时，Rb₁b₀指示的状态为100～111，对应的MCS的索引为4～7共4种状态。举例来说，若第一MCS索引＝0～7，当UL grant中的R置为1时，第二MCS索引的范围为8～15，对应的TBS索引取值为8～14，其中第一MCS、第二MCS索引、TBS索引都是整数；若第一TBS索引＝0～3，当UL grant中的R置为1时，则联合编码后的第二TBS索引取值为4～7，其中，第一TBS索引、第二TBS索引都是整数。In an optional implementation manner, the terminal device determines, according to the reserved bit in the UL grant, a status indicating a field indication of the first index. For example, the existing field indicating the MCS index includes 3 bits, which is b ₂ b ₁ b ₀ , the reserved bit is R, and the combined field obtained is Rb ₂ b ₁ b ₀ , when the R in the UL grant is set to At 1 o'clock, the state indicated by Rb ₂ b ₁ b ₀ is 1000 to 1111, and the index of the corresponding MCS is 8 states of 8 to 17 in total. For another example, the existing field indicating the MCS index includes 3 bits, which is b ₂ b ₁ b ₀ , the reserved bits are R ₁ and R ₀ , and the combined fields obtained are R ₁ R ₀ b ₂ b ₁ b ₀ When R in the UL grant is set to 1, the state indicated by R ₁ R ₀ b ₂ b ₁ b ₀ is 01000 to 11111, and the index of the corresponding MCS is 8 to 31. For example, in CE ModeB, the existing field indicating the TBS index contains 2 bits, which is b ₁ b ₀ , the reserved bit is R, and the combined field is Rb ₁ b ₀ ; when the R in the UL grant is set When it is 1, the state indicated by Rb ₁ b ₀ is 100 to 111, and the index of the corresponding MCS is 4 to 7 in total. For example, if the first MCS index is 0 to 7, when the R in the UL grant is set to 1, the range of the second MCS index is 8 to 15, and the corresponding TBS index is 8 to 14, wherein the first The MCS, the second MCS index, and the TBS index are all integers; if the first TBS index is 0 to 3, when the R in the UL grant is set to 1, the joint encoded second TBS index is 4 to 7. The first TBS index and the second TBS index are all integers.

然后，终端设备根据资源分配字段指示的资源指示值，确定第一物理资源数；这里，确定第一物理资源数的方法可以采用图8的步骤102中的确定第一物理资源数的方法。接着，终端设备根据第一物理资源数和第二索引，在传输块大小表格中查询与第一物理资源数和第二索引对应的TBSize。进而，终端设备可以将查询到的传输块大小，作为上行信息的传输块大小。并且，在查询到的传输块大小小于等于预设比特值时，终端设备确定查询到的传输块大小为上行信息的传输块大小；在查询到的传输块大小大于预设比特值时，终端设备确定预设比特值为上行信息的传输块大小；或者，在查询到的传输块大小大于预设比特值时，终端设备将TBS索引进行回退，直至查找到一个小于等于预设比特值的传输块大小，并将该传输块大小作为上行信息的传输块大小，同时，这种情况下，终端设备保持查表所用的物理资源数不变。在可选的一种实施方式中，预设比特值为1000比特。Then, the terminal device determines the first physical resource number according to the resource indication value indicated by the resource allocation field. Here, the method for determining the first physical resource number may adopt the method for determining the first physical resource number in step 102 of FIG. 8 . Next, the terminal device queries the TBSize corresponding to the first physical resource number and the second index in the transport block size table according to the first physical resource number and the second index. Furthermore, the terminal device can use the queried transport block size as the transport block size of the uplink information. And, the size of the transport block that is queried is less than or equal to the preset bit value. The terminal device determines that the queried transport block size is the transport block size of the uplink information; when the queried transport block size is greater than the preset bit value, the terminal device determines that the preset bit value is the transport block size of the uplink information; or When the queried transport block size is greater than the preset bit value, the terminal device rewinds the TBS index until a transport block size less than or equal to the preset bit value is found, and the transport block size is used as the transport block of the uplink information. Size, at the same time, in this case, the number of physical resources used by the terminal device to keep the table looked unchanged. In an optional embodiment, the preset bit value is 1000 bits.

举例来说，预留比特位R置为1时，针对于CE ModeA的终端设备，终端设备可以根据指示第一索引的字段，确定出第二MCS索引可以为8～15中的任意一个值，对应的TBS索引取值为8～14。此时，终端设备可以在TBS表格中确定出的TBSize的范围如表14所示，此时，终端设备采用第一物理资源数的个数取值为1、2、3、6，TBS索引取值为8～14进行查表，对应的TBSize的数据最大为1736比特。但是由于CEModeA的终端设备限制了上行信息的最大TBSize不可以超过预设比特值，例如该预设比特值为1000比特，进而此时确定TBSize的数据最大为936比特。For example, when the reserved bit R is set to 1, the terminal device can determine, according to the field indicating the first index, that the second MCS index can be any one of 8 to 15, according to the terminal device of the CE ModeA. The corresponding TBS index is 8 to 14. At this time, the range of the TBSize that the terminal device can determine in the TBS table is as shown in Table 14. At this time, the number of the first physical resource used by the terminal device is 1, 2, 3, and 6, and the TBS index is taken. The value is 8 to 14 for table lookup, and the corresponding TBSize data is up to 1736 bits. However, since the terminal device of the CEModeA limits the maximum TBSize of the uplink information to not exceed the preset bit value, for example, the preset bit value is 1000 bits, and thus the data of the TBSize is determined to be at most 936 bits.

表14步骤502针对CE ModeA的终端设备确定的TBSize的范围Table 14 Step 502: Range of TBSize determined for the terminal device of CE ModeA

又举例来说，预留比特位R置为1时，针对于CE ModeB的终端设备，终端设备可以根据指示第一索引的字段，确定出第二TBS索引可以为4～7中的任意一个值。此时，终端设备可以在TBS表格中确定出的TBSize的范围如表15所示，此时，终端设备采用第一物理资源数的个数取值为3、6，TBS索引取值为4～7进行查表，对应的TBSize的数据最大为712比特。并且，CE ModeB的终端设备可以限制了上行信息的最大TBSize不可以超过预设比特值，例如该预设比特值为1000比特。 For example, when the reserved bit R is set to 1, the terminal device can determine, according to the field indicating the first index, that the second TBS index can be any one of 4 to 7 for the terminal device of the CE ModeB. . At this time, the range of the TBSize that can be determined by the terminal device in the TBS table is as shown in Table 15. At this time, the number of the first physical resource used by the terminal device is 3, 6, and the value of the TBS index is 4 to 7 to check the table, the corresponding TBSize data is up to 712 bits. Moreover, the terminal device of the CE ModeB can limit the maximum TBSize of the uplink information to not exceed the preset bit value, for example, the preset bit value is 1000 bits.
