Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

In the related art, the configuregrant and the msg a PUSCH are basic information for configuring, by the network side, a PUSCH for transmitting uplink data, and include MCS information.

Configuration information (configuredprintconfig information element) of the Configured grant is as follows:

in the configuration information of the Configured grant, the underlined and bolded part is MCS information.

The configuration information (MsgA-PUSCH-configuration information element) of the PUSCH for transmitting msg a in 2-STEP RA is as follows:

in the 2-STEP RA, the underlined and bolded parts in the configuration information of the PUSCH for transmitting msg a are MCS information.

The MCS information in the Configured grant and the msg a PUSCH for transmitting the uplink data is Configured by the network side, and a terminal (User Equipment, UE) cannot perform MCS adaptive adjustment according to the current Radio Resource Control (RRC) state, the buffer data amount, and the like, for example, for a case where only a small amount of data needs to be transmitted by the terminal side, the terminal may improve the reliability of transmission by adjusting the MCS level.

Referring to fig. 1, fig. 1 is a schematic flow chart of a transmission method according to an embodiment of the present invention, where the method is applied to a terminal, and includes the following steps:

step 11: receiving first information sent by a network side device, wherein the first information comprises information of at least two MCS or information of an MCS group, and the MCS group comprises at least two MCS;

that is to say, the network side device may configure a plurality of MCSs for the terminal to use, and specifically, the network side device may directly configure a plurality of MCSs for the terminal, or may configure a plurality of MCSs for the terminal in the form of MCS groups. The MCS set may be one set or multiple sets.

Step 12: selecting one MCS from the at least two MCSs to use. The at least two MCSs may be directly configured MCSs or MCSs in an MCS set (the same applies hereinafter, and the description of the repetition is omitted).

For example, the network side device may configure a plurality of MCSs for the terminal, so that when the terminal transmits the PUSCH in msg a of 2-STEP RA (or uplink data carried by msg a), the terminal selects an appropriate MCS according to the data amount of the PUSCH in msg a to modulate and encode the PUSCH in msg a.

As will be appreciated by those skilled in the art, PUSCH is used for transmitting uplink data.

The embodiment of the invention provides a data transmission scheme of a terminal in a self-adaptive mode on uplink resource configuration, and network side equipment can configure a plurality of MCS (modulation and coding schemes) for the terminal, so that the terminal can select a proper MCS to use according to actual needs, and the data transmission efficiency and the transmission reliability are improved.

The above-described transmission method is exemplified below.

Optionally, the selecting one MCS from the at least two MCSs comprises:

That is, the terminal may select one MCS from a plurality of MCSs configured by the network side device to use, for example, for transmitting PUSCH in msg a, according to at least one of the current channel related information, the buffer data amount, and the radio resource control state.

Of course, the terminal may also select MCS according to other decision conditions, which is not exhaustive here.

The buffer Data amount may specifically be a size of Data to be transmitted buffered in the terminal, where the Data to be transmitted buffered in the terminal includes Data buffered in a Service Data Attachment Protocol (SDAP) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer, and of course, if there is no Data to be transmitted buffered in one or more Protocol function layers, the Data buffered in the corresponding layer does not need to be considered.

The channel-related information may be channel conditions including Synchronization Signal/physical broadcast channel Signal Block (SSB) (i.e., SS/PBCH Block) quality, Reference Signal Received Power (RSRP) of the SSB, and the like.

Optionally, the first information is carried by broadcast information and/or radio resource control release message (RRC release message).

That is, the broadcast message may carry the first information, and the RRC release message may also carry the first information.

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

Further, the first information may be carried in a suspend configuration (suspend config) in the RRC release message.

In an optional specific implementation manner, the receiving first information sent by the network side device includes:

receiving the broadcast information carrying the first information sent by the network side equipment;

after receiving the broadcast information, if two-step random access is to be initiated, the terminal may select one MCS of the multiple MCSs indicated by the first information carried in the broadcast information according to actual needs (for example, the size of data that needs to be carried), to transmit the PUSCH of msg a.

Receiving the RRC release message carrying the first information and sent by the network side equipment;

after receiving the RRC release message, the terminal switches to an inactive state, and if uplink data needs to be sent after the terminal is in the inactive state, according to actual needs, one MCS may be selected from multiple MCSs indicated in the first information carried by the RRC release message to modulate and encode the data to be uploaded.

Of course, in other optional specific embodiments, only the broadcast information may carry the first information, and the RRC release message does not carry the first information, specifically, the RRC release message may not carry information related to an MCS, and may also carry second information, where the second information includes only information related to an MCS. Or, only the RRC release message carries the first information, the broadcast information does not carry the first information, and the broadcast information may carry the second information, where the second information only includes information related to one MCS.

In other words, the plurality of MCSs configured by the RRC release message may be the same as the plurality of MCSs configured by the broadcast information; the plurality of MCSs configured by the RRC release message may be different from the plurality of MCSs configured by the broadcast information, that is, the RRC release message may update the MCSs configured in the broadcast information.

Optionally, if the first information is carried by the broadcast information, the selecting one MCS from the at least two MCSs to use includes:

Optionally, if the first information is carried by the rrc release message, the selecting one MCS from the at least two MCSs for use includes:

and selecting one MCS from at least two MCSs in the first information carried by the radio resource control release message to modulate and encode the PUSCH to be sent.

After receiving the RRC release message, the terminal may switch to the inactive state, and if uplink data needs to be sent after the terminal is in the inactive state, according to actual needs, one MCS may be selected from multiple MCSs indicated in the first information carried by the RRC release message to modulate and encode the data to be uploaded.

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

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

That is, the terminal may notify the network side device of the MCS selected by the terminal.

Specifically, the notification information may include absolute index (index) information of the MCS selected by the terminal, where a value of the index is 0 to 15 and occupies 4 bits (bit). The notification information may include relative information of the MCS selected by the terminal, for example, the MCS selected by the terminal is indicated according to the order of the MCS configured by the network side device, and when the network side device configures L MCSs, the occupied bit number is N, 2^N≤L＜2^N-1。

For example, the terminal may indicate information of MCS selected by the terminal for transmitting PUSCH in msg a through msg a (PUSCH).

modulating and coding the PUSCH to be transmitted by using the selected MCS;

That is, the corresponding relationship between the uplink resource and the at least two MCSs is carried by the first information.

Referring to fig. 2, fig. 2 is a schematic flow chart of a transmission method according to a second embodiment of the present invention, where the method is applied to a network side device, and includes the following steps:

step 21: and sending first information, wherein the first information comprises information of at least two MCSs or information of an MCS group, and the MCS group comprises at least two MCSs.

In an optional specific embodiment, the sending the first information includes:

transmitting the broadcast information to a terminal;

and sending the radio resource control release message to the terminal.

Optionally, the method includes:

receiving a PUSCH sent by a terminal;

Specifically, the network side device may sequentially analyze the PUSCH transmitted by the terminal by using MCSs corresponding to the information of the at least two MCSs directly carried in the first information, or may sequentially analyze the PUSCH transmitted by the terminal by using the at least two MCSs in the MCS set.

In the embodiment of the invention, if the terminal does not support reporting of the MCS selected by the terminal, the network side equipment does not have the corresponding relation between the uplink transmission resource and the MCS agreed with the terminal in advance, and the network side equipment does not have other means to know the MCS selected by the terminal, the network side equipment can only try to analyze the MCS configured to the terminal one by one successfully after acquiring the PUSCH at a certain time domain position.

Optionally, the method further includes:

receiving a PUSCH sent by a terminal;

It should be noted that the PUSCH is used for transmitting uplink data.

In the 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 by msga, and the network side device may analyze the PUSCH information according to the MCS information reported by the terminal.

In addition, the terminal may indicate the MCS selected by the terminal by transmitting the uplink resource of the PUSCH. Specifically, the network side device may configure a corresponding relationship between the uplink resource and the MCS in advance, and then, after the terminal selects a certain MCS, the terminal transmits the PUSCH using the uplink resource corresponding to the selected MCS.

For example, msg a includes a random access preamble (preamble) and uplink data (PUSCH), and the network side device may configure a correspondence between a preamble timing (occasion) and an MCS and/or a correspondence between a PUSCH occasion and the MCS in advance. After the terminal selects the MCS, the preamble is sent by using the preamble occasion corresponding to the selected MCS, or the PUSCH information is sent by using the PUSCH occasion corresponding to the selected MCS, and the network side equipment analyzes by using the MCS corresponding to the preamble occasion after receiving the PUSCH information, or analyzes by using the MCS corresponding to the PUSCH occasion.
