With the continuous development of AI technology and the continuous evolution of wireless communication systems, the 3rd Generation Partnership Project (3GPP) is currently discussing the combination of AI technology and communication technology. For AI-enabled channel state information (CSI) compression and recovery, the terminal device needs to use the AI model to compress the channel information it obtains and then report it to the network side; correspondingly, the network side will also use the AI model to perform corresponding decompression in order to restore the channel information.

Of course, the terminal device can also perform corresponding processing (such as encoding, quantization, etc.) on the compressed information before reporting it to the network device, and there is no specific restriction on this.

Correspondingly, after receiving the compressed information from the terminal device, the network device will input the compressed information into the AI module for corresponding decompression in order to recover the channel information/CSI parameters, thereby realizing CSI recovery through the AI model.

Specifically, the prediction information may include channel information/CSI parameters corresponding to one or more times/moments/time units/time domain positions after the one or more CSI-RS transmission opportunities.

The time unit can be understood as the communication granularity in the time domain. For example, the time unit can be a subframe, a time slot, a symbol, a mini-time slot, etc., and there is no specific limitation on this.

In some possible implementations, the terminal device can detect beam information such as beam distribution/beam signal strength at the current moment/current time, and then input the beam information into the AI model for prediction to obtain predicted beam information, thereby realizing beam prediction through the AI model.

For example, the predicted beam information may include beam information such as beam distribution/beam signal strength at a moment after the current moment/current time, and may also include beam information such as beam distribution/beam signal strength of an unmeasured beam at the current moment/current time.

In some possible implementations, the terminal device can input partial beam information into the AI model for prediction to obtain all beam information or beam information of unmeasured beams, thereby realizing beam prediction through the AI model.

3. Communication process under the combination of AI technology and communication technology

1. Description

Combined with the content in "II. Combination of AI technology and communication technology" above, in order to perform AI-based CSI reporting, the terminal device may determine CQI and/or RI based on the obtained channel information. However, there may be a deviation between the channel information obtained by the terminal device and the channel information restored by the network device, which may cause the CQI and/or RI determined by the terminal device to be incompatible with the channel information restored by the network device and/or the determined precoding/CSI parameters, etc., and this incompatibility will affect the reliability of communication transmission.

Based on this, the embodiment of the present application introduces parameter information, and determines CQI and/or RI based on the parameter information, so as to avoid as much as possible the incompatibility between the CQI and/or RI determined by the terminal device and the channel information recovered by the network device, the determined precoding information/CSI parameters, etc., thereby facilitating the adaptation and accuracy of CQI and/or RI, and ensuring the reliability of communication transmission.

2. Specific instructions

The technical solutions, beneficial effects, concepts, etc. involved in the embodiments of the present application are described in detail below.

1) Parameter information

It should be noted that for AI-enabled CSI compression and recovery, the CQI and/or RI determined by the terminal device may not be compatible with the channel information recovered by the network device and/or the precoding information/CSI parameters determined. parameter information so as to avoid the incompatibility problem as much as possible according to the parameter value indicated by the parameter information.

For example, after obtaining the parameter information, the terminal device can compensate the CQI and/or RI according to the parameter value indicated by the parameter information, so that the compensated CQI and/or RI of the terminal device is as adaptable as possible to the channel information recovered by the network device and/or the determined precoding information/CSI parameters, etc.

Of course, the parameter information may also be described using other terms, such as compensation information, compensation factor, etc., and there is no specific limitation on this.

In some possible implementations, the parameter value indicated by the parameter information may be one or more, and there is no limitation on this.

2) How to obtain parameter information

It should be noted that the embodiments of the present application can adopt a variety of methods to obtain parameter information in order to improve flexibility and adapt to various communication scenario requirements.

For example, the parameter information may be configured by the network, that is, the parameter information is sent to the terminal device through the network device, so that the terminal device acquires the parameter information.

For another example, the parameter information may be pre-configured or specified by a protocol. That is, the parameter information is configured to the terminal device in a pre-configured or protocol-specified manner, so that the terminal device acquires the parameter information.

3) Network configuration parameter information

It should be noted that the embodiment of the present application can carry the parameter information through network signaling, and the network signaling may include at least one of RRC signaling, MAC signaling, and downlink control information (Downlink Control Information, DCI).

In this way, the network device can send the network signaling to the terminal device, so that the terminal device receives the network signaling to obtain the parameter information, thereby realizing the network configuration of the parameter information.

4) Identification information

It should be noted that for AI-enabled CSI compression and recovery, the terminal device can determine the CQI and/or RI based on the obtained channel information, and then use the AI model to compress the channel information obtained by itself, and finally report it to the network device; correspondingly, the network device will also use the AI model to perform corresponding decompression in order to restore the channel information.

In order to ensure the consistency of the AI model used by the terminal device and the AI model used by the network device, the embodiment of the present application introduces identification information, and the identification information is used to indicate the identification of the AI model.

In this way, the network device can send the identification information to the terminal device, so that the terminal device receives the identification information to know which AI model should be used, so as to ensure the consistency of the AI model.

Of course, the network device may not send the identification information to the terminal device. In this case, the terminal device may use the default AI model.

In addition, the network device may only send parameter information to the terminal device without sending identification information. In this case, the parameter value indicated by the parameter information may be applicable to all default AI models.

In some possible implementations, the identification information may be carried by network signaling, thereby enabling the network to configure the identification information.

It should be noted that the network signaling carrying parameter information and the network signaling carrying identification information may be the same network signaling or may be different network signaling.

That is to say, the embodiments of the present application can carry parameter information and identification information at the same time through the same network signaling, so as to realize the network configuring parameter information and identification information at the same time; or, carry parameter information and identification information respectively through different network signaling, wherein the network signaling carrying the parameter information and the network signaling carrying the identification information can be sent successively or simultaneously, and there is no specific limitation on this.

In some possible implementations, the identification information may also be used to indicate a CSI report identification.

In some possible implementations, the identifier of the AI model indicated by the identification information may be one or more, and no specific limited.

5) There is an association between the parameter value indicated by the parameter information and the identifier of the AI model

①Description

It should be noted that the parameter value indicated by the parameter information of the embodiment of the present application may have an association relationship with the identifier of the AI model, wherein the association relationship may be implicit or explicit.

In this way, the terminal device can not only determine the CQI and/or RI based on the acquired channel information, but also supplement the CQI and/or RI based on the parameter value indicated by the parameter information to ensure adaptation and accuracy. At the same time, the terminal device can also compress the acquired channel information according to the AI model associated with the parameter value, and finally report it to the network device.

②The association is implicit

Combined with the content in the above "4) Identification Information", the embodiment of the present application can carry parameter information and identification information at the same time through the same network signaling. At this time, there is an implicit association between the parameter value indicated by the parameter information and the identifier of the AI model indicated by the identification information. Alternatively, the embodiment of the present application can only carry parameter information through network signaling. At this time, the parameter value indicated by the parameter information can be applied to all AI models by default, indicating that there is an implicit association between the parameter value indicated by the parameter information and all AI models.

In addition, since the parameter value indicated by the parameter information can be one or more, and the identifier of the AI model indicated by the identifier information can also be one or more, one parameter value can be associated with the identifier of at least one AI model, or multiple parameter values can be associated with the identifier of one AI model.

For example, the parameter value and the identifier of the AI model associated with it can be in two adjacent bytes of the network signaling.

For example, taking the network signaling as MAC signaling, the MAC signaling includes multiple bytes, each byte includes 8 bits. Among them, the first byte carries the parameter value, the second byte carries the identifier of the AI model, the third byte carries the parameter value, the fourth byte carries the identifier of the AI model, and so on. At this time, the parameter value carried by the first byte is associated with the identifier of the AI model carried by the second byte; the parameter value carried by the third byte is associated with the identifier of the AI model carried by the fourth byte, and so on.

For example, the parameter value and the identifier of the AI model associated with it can be in two adjacent fields of the network signaling.

For example, taking the network signaling as DCI as an example, the DCI includes multiple reserved fields. Among them, the first reserved field indicates the parameter value, the second reserved field indicates the identifier of the AI model, the third reserved field indicates the parameter value, and the fourth reserved field carries the identifier of the AI model, and so on. At this time, the parameter value indicated by the first reserved field is associated with the identifier of the AI model indicated by the second reserved field; the parameter value indicated by the third reserved field is associated with the identifier of the AI model indicated by the fourth reserved field, and so on.

③The association is explicit

a. Description

It should be noted that since only one of the parameter information and the identification information may need to be configured, or the parameter information and the identification information are not carried by the same network signaling, the embodiments of the present application can also configure the explicit association relationship between the parameter value indicated by the parameter information and the identification of the AI model according to network configuration, pre-configuration, etc.

In this way, when only one of the parameter information and the identification information is configured, the terminal device can also determine the other one based on the explicit association relationship, so as to perform the above operations to avoid incompatibility and ensure the consistency of the AI model. Alternatively, when the parameter information and the identification information are not carried by the same network signaling, the terminal device can also learn the association relationship between them based on the explicit association relationship.

For example, after the terminal device learns the parameter value indicated by the parameter information, it can determine the AI model used based on the explicit association relationship; or, after the terminal device learns the AI model used, it can determine the parameter value used based on the association relationship.

In addition, the explicit association relationship between the parameter value indicated by the parameter information of the embodiment of the present application and the identifier of the AI model can be obtained through multiple This is achieved in a manner that helps to improve the flexibility of configuring the association relationship so as to adapt to various communication scenario requirements. The following is a detailed description.

b. A parameter value is associated with the identifier of at least one AI model

It should be noted that a parameter value is associated with the identifier of at least one AI model. In this way, after the terminal device obtains the parameter value indicated by the parameter information, it can determine the identifier of at least one AI model from the above-mentioned association relationship; or, after the terminal device obtains the identifier of the AI model, it can determine a parameter value from the above-mentioned association relationship.

Since a parameter value may be associated with the identifiers of multiple AI models, and the terminal device may know the parameter value first, the embodiment of the present application needs to determine one from the identifiers of the multiple AI models so that the terminal device can finally use it.

To this end, the present application may adopt at least one of the following methods:

The first is that the terminal device directly selects the smallest identifier from the identifiers of the multiple AI models to use.

The second is that the terminal device directly selects the largest identifier from the identifiers of the multiple AI models to use.

The third is that the terminal device directly selects any one identifier from the multiple AI model identifiers to use.

The fourth is that the network indicates one from the identifiers of the multiple AI models.

For example, the network indicates one from the identifiers of the multiple AI models through DCI.

It can be seen that the embodiments of the present application can adopt a variety of methods to determine one from the identifiers of multiple AI models, which is conducive to improving flexibility and adapting to the needs of various communication scenarios.

c. Multiple parameter values are associated with an AI model identifier

It should be noted that multiple parameter values are associated with the identifier of an AI model. In this way, after the terminal device obtains the parameter value indicated by the parameter information, it can determine the identifier of an AI model from the above-mentioned association relationship; or, after the terminal device obtains the identifier of the AI model, it can determine multiple parameter values from the above-mentioned association relationship.

Since multiple parameter values are associated with the identifier of an AI model, and the terminal device may first know the identifier of the AI model, the embodiment of the present application needs to determine one from the multiple parameter values so that the terminal device can use it.

To this end, the present application may adopt at least one of the following methods:

The first one is that the terminal device directly selects the minimum value from the multiple parameter values for use.

The second is that the terminal device directly selects the maximum value from the multiple parameter values for use.

The third is that the terminal device directly selects any one value from the multiple parameter values to use.

A fourth type is that the network indicates one from the multiple parameter values.

For example, the network indicates one from the multiple parameter values through DCI.

It can be seen that the embodiments of the present application can adopt multiple methods to determine one from multiple parameter values, which is conducive to improving flexibility and adapting to various communication scenario requirements.

6) Network signaling

①Description

In combination with the above, it can be known that the embodiment of the present application can carry parameter information and/or identification information through network signaling to implement network configuration. Among them, the network signaling can include at least one of RRC signaling, MAC signaling, and DCI. The following embodiment of the present application is mainly described by taking MAC signaling and DCI as examples.

②MAC signaling

In an embodiment of the present application, MAC signaling may include a MAC control element (MAC CE).

In this way, network configuration is implemented by carrying parameter information and/or identification information through MAC CE.

In order to implement MAC CE to carry parameter information and/or identification information, MAC CE may include at least one of at least one first-class bit, at least one second-class bit, at least one third-class bit, etc. Among them, the values of each first-class bit may be the same or different; the values of each second-class bit may be the same or different; the values of each third-class bit may be the same or different. The following are respectively explained.

◆First Class Bit

In an embodiment of the present application, the first type of bit can be used to indicate whether parameter information and/or identification information exists in the next byte of the byte where the first type of bit is located.

In this way, it can be determined through the first type of bits whether there is parameter information and/or identification information in the next byte.

Specifically, the number of bits of the first type of bits may be one or more.

For example, taking the number of bits of the first type of bit as one, the first type of bit is one bit in a byte. If the value of the bit is 1, it means that the next byte of the byte where the bit is located has parameter information and/or identification information; if the value of the bit is 0, it means that the next byte of the byte where the bit is located does not have parameter information and/or identification information. On the contrary, if the value of the bit is 1, it means that the next byte of the byte where the bit is located does not have parameter information and/or identification information; if the value of the bit is 0, it means that the next byte of the byte where the bit is located has parameter information and/or identification information.

Specifically, the first type of bit can be located at the first one or more bits in a byte, at the last one or more bits in a byte, or at any bit in a byte. In this way, the location of the first type of bit can be flexibly set according to actual communication conditions.

For example, if the number of the first type of bits is one and the first type of bits is located at the first bit in the byte, the first type of bits is the first bit in the byte. In this way, when decoding the bytes in the MAC CE, the first type of bits can be decoded first, so as to know whether there is a next byte first.

In some possible implementations, a MAC CE may include multiple first-class bits, wherein each first-class bit may be located in a different byte of the MAC CE; and the values of each first-class bit may be the same or different.

For example, taking a MAC CE including three first-class bits, the three first-class bits are the first first-class bit, the second first-class bit, and the third first-class bit.

The first first-class bit is located at the first byte of MAC CE, the second first-class bit is located at the second byte of MAC CE, and the third first-class bit is located at the third byte of MAC CE.

The three first-category bits are all 1 bit; among them, the value of the first first-category bit is 0, the value of the second first-category bit is 1; and the value of the third first-category bit is 0.

◆ Type II Bit

In an embodiment of the present application, the second type of bits can be used to indicate the above-mentioned parameter information.

Specifically, the number of the second type of bits may be multiple. In this case, the second type of bits is multiple bits in a byte, and the multiple bits are used to determine the CQI and/or RI.

Specifically, the position of the second type of bits can be on the first multiple bits in a byte, on the last multiple bits in a byte, on any bit in a byte, distributed in a single byte, or distributed in multiple bytes. In this way, the position of the second type of bits can be flexibly set according to actual communication conditions.

For example, taking the position of the second type of bits distributed in two bytes as an example, the position of the second type of bits can be distributed in two consecutive bytes. This is because the bits used to indicate parameter information in the first byte are limited, so some bits in the second byte are needed to jointly indicate the parameter information.

In some possible implementations, a MAC CE may include multiple second-class bits. Each second-class bit may be located at On different bytes of the MAC CE, the values of each second type bit may be the same or different.

For example, taking a MAC CE including three second-class bits, the three second-class bits are the first second-class bit, the second second-class bit, and the third second-class bit.

The first second-class bit is located at the first byte of MAC CE, the second second-class bit is located at the second byte of MAC CE, and the third second-class bit is located at the third byte of MAC CE.

The three second-category bits are all 2 bits; among them, the value of the first second-category bit is "00", which means that the parameter value indicated by the first second-category bit is K1; the value of the second first-category bit is "01", which means that the parameter value indicated by the second second-category bit is K2; the value of the third second-category bit is "10", which means that the parameter value indicated by the third second-category bit is K3.

◆The third type of bit

In an embodiment of the present application, the third type of bits can be used to indicate the above-mentioned identification information.

Specifically, the number of bits of the third type of bits may be one or more. In this case, the third type of bits are regarded as one or more bits in a byte, and the one or more bits are used to identify the AI model.

Specifically, the position of the third type of bits can be on the first multiple bits in a byte, on the last multiple bits in a byte, on any bit in a byte, distributed in a single byte, or distributed in multiple bytes. In this way, the position of the third type of bits can be flexibly set according to actual communication conditions.

For example, taking the position of the third type of bits distributed in two bytes as an example, the position of the third type of bits can be distributed in two consecutive bytes. This is because the bits used to identify the AI model in the first byte are limited, so some bits in the second byte are needed to jointly identify the AI model.

In some possible implementations, a MAC CE may include multiple third-category bits, wherein each third-category bit may be located in a different byte of the MAC CE; and the values of each third-category bit may be the same or different.

For example, taking a MAC CE including three third-category bits, the three third-category bits are the first third-category bit, the second third-category bit, and the third third-category bit.

The first third-category bit is located at the first byte of MAC CE, the second third-category bit is located at the second byte of MAC CE, and the third third-category bit is located at the third byte of MAC CE.

The three third-category bits are all 2 bits; among them, the value of the first third-category bit is "00", the value of the second third-category bit is "01"; and the value of the third third-category bit is "10".

③DCI

a.DCI is public control information

Description

It should be noted that the DCI of the embodiment of the present application may be public control information. Wherein, DCI is public control information, which can be understood as that the DCI can be sent to multiple terminal devices in a group, similar to a multicast mode, and the DCI will carry parameter information and/or identification information.

◆The first dedicated Radio Network Temporary Identity (RNTI)

Since terminal devices in some groups need to perform CQI and/or RI compensation, while terminal devices in another group do not need to perform CQI and/or RI compensation, the DCI belonging to the public control information may carry parameter information and/or identification information, or may not carry parameter information and/or identification information. Therefore, in order to distinguish, an embodiment of the present application introduces a first dedicated RNTI, which is used for the transmission of parameter information and/or identification information, and the cyclic redundancy check (Cyclic Redundancy Check, CRC) of the PDCCH used to carry the DCI is scrambled by the first dedicated RNTI to indicate that the DCI will carry parameter information and/or identification information.

In this way, when terminal devices in some groups need to perform CQI and/or RI compensation, these terminal devices can use the first dedicated RNTI to perform corresponding descrambling in order to obtain parameter information and/or identification information.

◆Block in DCI

Since DCI belonging to public control information will be sent to multiple terminal devices in a group, and different terminal devices in the group may need to be configured with different parameter information and/or identification information, in order to distinguish them, the DCI may include at least one block, and different blocks are used to configure different terminal devices, and each block may carry parameter information and/or identification information. For a terminal device, which block belongs to it can be learned through high-level configuration information.

b.DCI is user-specific control information

Description

It should be noted that the DCI of the embodiment of the present application may be user-specific control information, which can be understood as that the DCI is specifically sent to a specific terminal device, and the DCI will carry parameter information and/or identification information.

◆Second dedicated RNTI

In order to determine to which terminal device the DCI belonging to the user-specific control information is sent, an embodiment of the present application introduces a second dedicated RNTI, which is used to identify the terminal device, and the CRC of the PDCCH used to carry the DCI is scrambled by the second dedicated RNTI, so that the DCI is sent to a dedicated terminal device.

In this way, the terminal device identified by the second dedicated RNTI can use the second dedicated RNTI to perform corresponding descrambling in order to obtain parameter information and/or identification information.

◆DCI is used for non-scheduling

It should be noted that the DCI belonging to user-specific control information may be used for non-scheduling. In this case, some existing fields in the DCI may not indicate the original information.

For example, the frequency domain resource assignment field in the DCI may not indicate the frequency domain resources to the terminal device; the new data indicator (NDI) field in the DCI may not indicate the newly transmitted data to the terminal device; the HARQ process number (HARQ process number) field in the DCI may not indicate to the terminal device which HARQ process is used for this transmission application; the redundancy version (RV) field in the DCI may not indicate the redundancy version to the terminal device; the modulation and coding scheme (MCS) field in the DCI may not indicate the modulation mode, coding rate and transmission block size, etc. to the terminal device.

Based on this, the embodiments of the present application can reuse the existing fields in the DCI to improve the utilization efficiency. The term "reuse" can also be understood as "reuse" and is not specifically limited thereto.

For example, which existing field or fields in the DCI can be used for multiplexing may be specified by the protocol. For example, the protocol directly specifies that the frequency domain resource allocation field in the DCI is used for multiplexing, and directly specifies the value of the frequency domain resource allocation field.

For example, which existing field or fields in the DCI can be used for multiplexing can be indicated by the network. For example, there is a field in the DCI, which is used to indicate which existing field or fields are used for multiplexing, and the field can be a newly added field, a reserved field, etc.

In some possible implementations, the existing fields used for multiplexing in the DCI may include at least one of the following: a frequency domain resource allocation field, an NDI field, a HARQ process number field, an RV field, an MCS field, a transmission power control command for a scheduled physical uplink control channel (TPC command for scheduled PUCCH) field, a PUCCH resource indication (PUCCH resource indicator) field, an antenna port (Antenna port(s)) field, a sounding reference signal request (SRS request) field, a demodulation reference signal sequence initialization (DMRS sequence initialization) field, a first downlink assignment index ( ^1st downlink assignment index) field, a transmission power control command for a scheduled physical uplink shared channel (TPC command for scheduled PUSCH), and a physical uplink shared channel for scheduling. Second transmission power control command (Second TPC command for scheduled PUCCH) field, downlink assignment index (Downlink assignment index) field, etc.

In some possible implementations, the existing fields in the DCI indicate in a multiplexed manner that the DCI carries parameter information and/or identification information.

For example, the existing field may be all 0s or all 1s to indicate that the DCI carries parameter information and/or identification information.

For example, taking the existing field as the NDI field, if the value of the NDI field is 0, it means that the DCI carries parameter information and/or identification information; on the contrary, if the value of the NDI field is 1, it means that the DCI carries parameter information and/or identification information.

For another example, taking the existing field as the RV field, if the value of the RV field is all 1, it means that the DCI carries parameter information and/or identification information. On the contrary, if the value of the RV field is all 0, it means that the DCI carries parameter information and/or identification information.

It should be noted that the existing fields here can also be other fields listed above in this application, which will not be repeated here.

Of course, the embodiment of the present application can jointly indicate that the DCI carries parameter information and/or identification information through one or more existing fields in a multiplexed manner.

For example, taking the two existing fields as the NDI field and the RV field as an example, the NDI field and the RV field can jointly indicate that the DCI carries parameter information and/or identification information. For example, if the value of the NDI field is 0 and the RV field is all 1, it means that the DCI carries parameter information and/or identification information; or, if the value of the NDI field is 1 and the RV field is all 1, it means that the DCI carries parameter information and/or identification information, and so on.

It should be noted that the existing fields here can also be other fields listed above in this application, which will not be repeated here.

In some possible implementations, the existing fields in the DCI are multiplexed to indicate that the DCI does not carry parameter information and/or identification information.

For example, taking the existing field as the NDI field, if the value of the NDI field is 0, it means that the DCI does not carry parameter information and/or identification information; on the contrary, if the value of the NDI field is 1, it means that the DCI does not carry parameter information and/or identification information.

For another example, taking the existing field as the RV field, if the RV field is all 0s, it means that the DCI does not carry parameter information and/or identification information.

It should be noted that the existing fields here can also be other fields listed above in this application, which will not be repeated here.

Of course, the embodiment of the present application can use one or more existing fields in a multiplexed manner to jointly indicate that the DCI does not carry parameter information and/or identification information.

In some possible implementations, the existing fields in the DCI indicate parameter information and/or identification information in a multiplexed manner.

For example, taking the existing field as a HARQ process number field as an example, the HARQ process number field indicates parameter information in a multiplexed manner. For another example, taking the existing field as an MCS field as an example, the MCS field indicates identification information in a multiplexed manner.

It should be noted that the existing fields here can also be other fields listed above in this application, which will not be repeated here.

Of course, the embodiments of the present application can jointly indicate parameter information and/or identification information through one or more existing fields in a multiplexed manner, which will not be described in detail.

◆DCI is used for scheduling

It should be noted that the DCI belonging to user-specific control information may be used for scheduling. In this case, the existing fields in the DCI will indicate the original information.

Based on this, the embodiments of the present application may add new fields or newly define fields for the DCI, or utilize the reserved resources in the DCI for use.

In some possible implementations, there is a new field or a reserved field in the DCI, and the new field or the reserved field is used to indicate that the DCI carries parameter information and/or identification information, or does not carry parameter information and/or identification information.

In some possible implementations, there is a new field or a reserved field in the DCI, and the new field or the reserved field is used to indicate the parameter information and/or identification information.

Furthermore, the field used to indicate parameter information and the field used to indicate identification information may be adjacent to each other.
