[0103] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0104] In the related art, configuredgrant and msg A PUSCH are both basic information of PUSCH configured by the network side for transmitting uplink data, which includes MCS information.

[0105] The configuration information of Configured grant (ConfiguredGrantConfig information element) is as follows:

[0106]

[0107] In the configuration information of the above Configured grant, the underlined and bolded part is the MCS information.

[0108] The configuration information (MsgA-PUSCH-Config informationelement) of the PUSCH for transmitting msg A in 2-STEP RA is as follows:

[0109]

[0110]

[0111] In the configuration information of the PUSCH for transmitting msg A in the above 2-STEP RA, the underlined and bolded part is the MCS information.

[0112] The above-mentioned MCS information in the Configured grant and msg A PUSCH for transmitting uplink data is configured by the network side. The terminal (User Equipment, UE) cannot perform MCS adaptive adjustment according to the current Radio Resource Control (Radio Resource Control, RRC) state, the amount of cached data, etc. For example, when only a small amount of data needs to be transmitted on the terminal side, the terminal can improve the reliability of transmission by adjusting the MCS level.

[0113] See also Figure 1 , Figure 1 A schematic flow chart of a transmission method provided in Embodiment 1 of the present invention, wherein the method is applied to a terminal and comprises the following steps:

[0114] Step 11: receiving first information sent by a network side device, where the first information includes information of at least two MCSs or information of an MCS group, where the MCS group includes at least two MCSs;

[0115] That is to say, the network side device can configure multiple MCSs for the terminal for use by the terminal. Specifically, the network side device can directly configure multiple MCSs for the terminal, or can configure multiple MCSs for the terminal in the form of MCS groups. The MCS group can be one group or multiple groups.

[0116] Step 12: Select one MCS from the at least two MCSs for use. The at least two MCSs may be directly configured MCSs or MCSs in an MCS group (the same applies below, and the repetitions are not repeated).

[0117] For example, the network side device can configure multiple MCSs for the terminal so that when the terminal sends the PUSCH in msg A of 2-STEP RA (which can also be said to be the uplink data carried by msg A), it can select an appropriate MCS to modulate and encode the PUSCH in msg A according to the data volume of the PUSCH in msg A.

[0118] Those skilled in the art should understand that the PUSCH is used to transmit uplink data.

[0119] The embodiment of the present invention provides a terminal adaptive data transmission solution on the configuration of uplink resources. The network side device can configure multiple MCSs for the terminal, so that the terminal can select a suitable MCS for use according to actual needs, thereby improving data transmission efficiency and transmission reliability.

[0120] The above transmission method is described below with examples.

[0121] Optionally, the selecting one MCS from the at least two MCSs to use includes:

[0122] An MCS is selected from the at least two MCSs for use according to at least one of current channel-related information, a buffered data amount, and a radio resource control state.

[0123] That is to say, the terminal can select an MCS from multiple MCSs configured by the network side device based on at least one of the current channel-related information, the amount of cached data and the wireless resource control state, for example, for transmitting the PUSCH in msg A.

[0124] Of course, the terminal may also select the MCS according to other decision conditions, which are not listed here.

[0125] Regarding the amount of cached data, it can specifically be the size of the data to be transmitted cached in the terminal. The data to be transmitted cached in the terminal includes the data cached in the terminal-side Service Data Adaption Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC) layer and Media Access Control (MAC) layer. Of course, if there is no cached data to be transmitted in one or several of the protocol function layers, there is no need to consider the data cached in the corresponding layer.

[0126] Channel-related information may include channel conditions, including the quality of the synchronization signal / physical broadcast channel signal block (Synchronization Signal and PBCH block, SSB (ie, SS / PBCH Block)), such as the reference signal received power (Reference Signal Received Power, RSRP) of the SSB, etc.

[0127] Optionally, the first information is carried by broadcast information and / or a radio resource control release message (RRCrelease message).

[0128] That is to say, the broadcast information may carry the above-mentioned first information, and the RRC release message may also carry the above-mentioned first information.

[0129] The MCS indicated by the first information carried in the broadcast information can be used to modulate and encode the PUSCH in msg A. The MCS indicated by the first information carried in the RRC release message can be used to modulate and encode uplink data sent by the terminal when it is in an inactive state (RRC inactive state). In other words, the network side device can indicate the MCS used when the terminal is in the RRC inactive state in the RRC release message.

[0130] Furthermore, the first information may be carried in a suspend configuration in an RRC release message.

[0131] In one optional specific implementation manner, the receiving first information sent by the network side device includes:

[0132] Receiving the broadcast information carrying the first information sent by the network side device;

[0133] After receiving the broadcast information, if the terminal wants to initiate two-step random access, it can select one of the multiple MCSs indicated by the first information carried in the broadcast information to transmit the PUSCH of msg A according to actual needs (such as the size of the data to be carried).

[0134] Receiving the RRC release message carrying the first information sent by the network side device;

[0135] After receiving the RRC release message, the terminal switches to an inactive state. If uplink data needs to be sent in the inactive state, an MCS can be selected from multiple MCSs indicated in the first information carried by the RRC release message to modulate and encode the uploaded data according to actual needs.

[0136] Of course, in other optional specific implementations, only the broadcast information may carry the first information, and the RRC release message may not carry the first information. Specifically, the RRC release message may not carry information related to the MCS, and may carry the second information, and the second information only includes relevant information of one MCS. Alternatively, only the RRC release message carries the first information, and the broadcast information does not carry the first information. The broadcast information may carry the second information, and the second information only includes relevant information of one MCS.

[0137] Optionally, the first information carried by the broadcast information is the same as or different from the MCS information in the first information carried by the wireless resource control release message; or, the first information carried by the broadcast information is the same as or different from the MCS group information in the first information carried by the wireless resource control release message.

[0138] In other words, the multiple MCSs configured through the RRC release message can be the same as the multiple MCSs configured through the broadcast information; the multiple MCSs configured through the RRC release message can be different from the multiple MCSs configured through the broadcast information, that is, the RRC release message can update the MCS configured in the broadcast information.

[0139] Optionally, if the first information is carried by the broadcast information, the selecting an MCS from the at least two MCSs for use includes:

[0140] From at least two MCSs in the first information carried by the broadcast information, select one MCS to modulate and encode the PUSCH in msg A.

[0141] After receiving the broadcast information, if the terminal wants to initiate two-step random access, it can select one of the multiple MCSs indicated by the first information carried in the broadcast information to transmit the PUSCH of msg A according to actual needs (such as the size of the data to be carried).

[0142] Optionally, if the first information is carried by the radio resource control release message, the selecting an MCS from the at least two MCSs for use includes:

[0143] An MCS is selected from at least two MCSs in the first information carried in the radio resource control release message to modulate and encode a PUSCH to be sent.

[0144] After receiving the RRC release message, the terminal can switch to an inactive state. If uplink data needs to be sent in the inactive state, an MCS can be selected from multiple MCSs indicated in the first information carried by the RRC release message to modulate and encode the uploaded data according to actual needs.

[0145] In the embodiment of the present invention, uplink data is transmitted by PUSCH, and therefore may also be referred to as PUSCH information.

[0146] Optionally, after selecting one MCS from the at least two MCSs for use according to at least one of current channel-related information, buffered data volume, and radio resource control state, the method further includes:

[0147] Send notification information to the network side device, where the notification information is used to notify the network side device of the MCS used by the terminal.

[0148] That is to say, the terminal can notify the network side device of the MCS selected by the terminal.

[0149] Specifically, the notification information may include the absolute index information of the MCS selected by the terminal, the index value is 0-15, and occupies 4 bits. The notification information may include the relative information of the MCS selected by the terminal, for example, indicating the MCS selected by the terminal according to the order in which the network side device configures the MCS. When the network side device configures L MCSs, the number of bits occupied is N, 2 N ≤L<2 N-1 .

[0150] Optionally, the notification information is carried by a PUSCH modulated and encoded using the selected MCS or carried by msg A.

[0151] For example, the terminal may indicate, through msg A (preamble, PUSCH), information of the MCS selected by the terminal for transmitting the PUSCH in msg A.

[0152] Optionally, after selecting one MCS from the at least two MCSs for use according to at least one of current channel-related information, buffered data volume, and radio resource control state, the method further includes:

[0153] Modulate and code the PUSCH to be transmitted using the selected MCS;

[0154] The modulated and coded PUSCH is sent to the network side device using a first uplink resource, where the first uplink resource corresponds to the selected MCS.

[0155] Optionally, the first information also includes a correspondence between uplink resources and the at least two MCSs.

[0156] That is, the correspondence between the uplink resources and the at least two MCSs is carried by the first information.

[0157] See also Figure 2 , Figure 2 1 is a flow chart of a transmission method provided in Embodiment 2 of the present invention. The method is applied to a network side device and includes the following steps:

[0158] Step 21: Send first information, where the first information includes information of at least two MCSs or information of an MCS group, and the MCS group includes at least two MCSs.

[0159] That is to say, the network side device can configure multiple MCSs for the terminal for use by the terminal. Specifically, the network side device can directly configure multiple MCSs for the terminal, or can configure multiple MCSs for the terminal in the form of MCS groups. The MCS group can be one group or multiple groups.

[0160] The embodiment of the present invention provides a terminal adaptive data transmission solution on the configuration of uplink resources. The network side device can configure multiple MCSs for the terminal, so that the terminal can select a suitable MCS for use according to actual needs, thereby improving data transmission efficiency and transmission reliability.

[0161] Optionally, the first information is carried by broadcast information and / or a radio resource control release message.

[0162] In one optional specific implementation manner, the sending of the first information includes:

[0163] Sending the broadcast information to a terminal;

[0164] Sending the radio resource control release message to the terminal.

[0165] Optionally, the first information carried by the broadcast information is the same as or different from the MCS information in the first information carried by the wireless resource control release message; or, the first information carried by the broadcast information is the same as or different from the MCS group information in the first information carried by the wireless resource control release message.

[0166] Optionally, the method comprises:

[0167] Receiving PUSCH sent by the terminal;

[0168] The PUSCH sent by the terminal is parsed using the MCSs of the at least two MCSs in sequence until the parsing is successful.

[0169] Specifically, the network side device may sequentially use the MCS corresponding to the information of at least two MCSs directly carried in the first information to parse the PUSCH sent by the terminal, or may sequentially use at least two MCSs in the MCS group to parse the PUSCH sent by the terminal.

[0170] In an embodiment of the present invention, if the terminal is not supported to report the MCS selected by the terminal, the network side device has not agreed with the terminal in advance on the correspondence between the uplink transmission resources and the MCS, and the network side device has no other means to obtain the MCS selected by the terminal, then after the network side device obtains the PUSCH at a certain time domain position, it can only try one by one to see if the MCS configured for the terminal can be successfully parsed.

[0171] Optionally, the method further includes:

[0172] Receiving PUSCH sent by the terminal;

[0173] Parsing a PUSCH sent by the terminal using a first MCS among the at least two MCSs;

[0174] The first MCS corresponds to an uplink resource for sending a PUSCH by the terminal, or the first MCS is determined according to notification information of the terminal.

[0175] It should be noted that the PUSCH is used to transmit uplink data.

[0176] In an embodiment of the present invention, the terminal may notify the network side device of the MCS selected by the terminal. For example, the terminal may indicate the MCS selected by the terminal through msg A, and the network side device may parse the PUSCH information according to the MCS information reported by the terminal.

[0177] In addition, the terminal can also indicate the MCS selected by the terminal by sending the uplink resource of PUSCH. Specifically, the network side device can configure the correspondence between uplink resources and MCS in advance, and then after the terminal selects a certain MCS, it uses the uplink resource corresponding to the selected MCS to send PUSCH.

[0178] For example, msg A includes a random access preamble and uplink data (PUSCH). The network side device can configure the correspondence between the preamble occasion and the MCS and / or the correspondence between the PUSCH occasion and the MCS in advance. After the terminal selects the MCS, it sends the preamble using the preamble occasion corresponding to the selected MCS, or sends the PUSCH information through the PUSCH occasion corresponding to the selected MCS. After receiving the PUSCH information, the network side device uses the MCS corresponding to the preamble occasion for parsing, or uses the MCS corresponding to the PUSCH occasion for parsing.
