As shown in fig. 1B, in the frequency division duplex (frequency division duplex, FDD) mode, in order to perform downlink precoding that better matches the channel characteristics, a User Equipment (UE) needs to feed back a CSI report (report) obtained by processing to a network side, for example, a base station side (gNB) corresponding to an access network device.

Along with the high-precision requirement on the precoding matching channel characteristics, the UE also needs to feed back the CSI report with higher precision, the number of CSI report bits which the UE needs to feed back is also increased, and the overhead on an air interface is also increased. In order to reduce the overhead of the air interface as much as possible, the base station side can obtain good downlink channel state information.

In some embodiments, AI-based CSI compression is performed using a bilateral model, as shown in fig. 1C. Among them, the model on the UE side is called an Encoder (Encoder), or CSI generation model (generation model); the Network (NW) side model is called Decoder, or CSI reconstruction model (reconstruction model). The CSI reconstruction model may also be referred to as a CSI recovery model.

In order to ensure system performance, when performance of an artificial intelligence (artificial intelligence, AI) model is degraded, operations such as model switching and the like need to be performed in time. In order to monitor the performance of the model, model monitor (model monitor) is needed, and this operation can be divided into UE side monitor (UE side model monitor) and NW side monitor (NW side model monitor), and this scheme considers the NW side performance monitor as follows.

At this time, the UE side needs to feed back, in addition to the output (AI-based CSI report) of CSI generation model, a high-precision conventional CSI report (group-trunk CSI), as a baseline, to evaluate the performance of the AI model, so as to support the model performance monitoring on the NW side.

As shown in fig. 1D, an input (input) may be input to the CSI generating model and the high-precision CSI reconstruction model, and Loss values (Loss) are calculated for the outputs of the respective models with the corresponding CSI reports as labels, so as to obtain Loss1 and Loss2, respectively, and thus performance quality assessment of the AI model is achieved through the Loss value calculation.

As shown in fig. 1E, the conventional (Legacy) CSI report and the AI-based CSI report may overlap in the time domain, so that transmission of the two CSI reports collide.

In the existing standard, CSI in NR is completely reported in one time slot, but since the number of CSI bits is related to a part (RI) of CSI, that is, different RI selected by UE may result in different number of bits of CSI. Under the condition that the base station cannot determine the CSI bit number, the base station can only try various possibilities in a blind detection mode, so that the complexity is increased, and the performance cannot be guaranteed.

To solve the problem of ambiguity of CSI bit number, CSI report is split into two parts: a first part (part 1) and a second part (part 2). Wherein the number of bits of the first part (part 1) is fixed and the number of bits of the second part can be determined from the content of the first part (part 1), as in table 1.

TABLE 1

RI in table 1 is a rank indication, which is an abbreviation for rank indication.

PMI in table 1 is a precoding matrix indicator, which is an abbreviation of Precoding Matrix Indicator.

LI in Table 1 is a Layer indicator, which is an abbreviation for Layer indicator.

CQI in table 1 is an abbreviation for channel quality indication, channel Quality Indicator.

Wherein RI, CQI, and other information in the first part may be used to indicate the amount of data in the second part.

The amount of data of the first portion is fixed.

The second part includes at least the output of the CSI model.

CSI reporting supporting periodicity (Periodic, P) and semi-persistent (Semi Persistent On PUCCH, SP On PUCCH) On NR PUCCH.

Each CSI report transmitted through the PUCCH has a corresponding PUCCH resource. The configuration of CSI reporting may be as shown in fig. 1F. The configuration of the CSI report may include: report configuration identity (reportcongigiid), carrier configuration, serving cell identity (ServCellIndex), etc. The configuration at this CSI report has a report configuration type (reportConfigType). The CSI report type shown in fig. 1F indicates a periodic (periodic) report of the type. Meanwhile, in the configuration of the CSI report, there are resources configured to transmit the CSI report. The Resource that transmits the CSI report in fig. 1F may be a physical uplink control channel (Physcial Uplink Control Channel, PUCCH) Resource (PUCCH-CSI-Resource).

Fig. 1G shows that two PUCCH resources for transmitting CSI reports are configured in the same slot, and at this time, a transmission collision of CSI occurs. When more than one CSI report (Multi CSI) based on PUCCH transmission needs to be reported in the same slot, such collision can be solved in the manner shown in fig. 1H. Assuming that J Multi-CSI ucchs (Multi-CSI ucchs) are ordered from small to large in bearer capacity, CSI reports are traded off according to their priorities in order to ensure high priority CSI report transmission within the bearer capacity. The carrying capacity of the PUCCH resource can be calculated according to the factors of the target code rate, the time-frequency domain resource, the spread spectrum and the like.

At this time, regarding priority determination of CSI reports, the following provides a manner of priority determination of CSI reports:

Pri _iCSI (y，k，c，s)＝2·N _cells ·M _s ·y+N _cells ·M _s ·k+M _s ·c+s

wherein, the meaning represented by each parameter is as follows:

y=0 is used for aperiodic CSI reporting carried on PUSCH; y=1 is used for semi-persistent CSI reporting carried on PUSCH; y=2 is used for semi-persistent CSI reporting carried on PUCCH; y=3 is used for periodic CSI reporting carried on PUCCH;

k=0 represents CSI reporting of the reference signal received power (Layer one-Reference Signal Recived Power, L1-RSRP) of the bearer Layer 1, and k=1 represents CSI reporting of not carrying the L1-RSRP;

c represents a serving cell index;

N _cells a value of a maximum number of serving cells (maxNrofServingCells) which is a higher layer parameter;

s is the value of the reporting configuration identity (reportConfigID) of the higher layer parameters;

M _s is the value of the maximum number of CSI report configurations (maxNrofCSI-ReportConfigurations) of the higher layer parameters;

global priority value Pri _iCSI The smaller the priority indicating the CSI report is higher.

If the time domain occupancy of the physical channel scheduled to carry CSI reports overlaps in at least one orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol and is transmitted on the same carrier, then two CSI reports are said to collide.

When the UE configures to transmit two conflicting CSI, if the y value between the two reported CSI is different, CSI report with lower priority value will be transmitted. Unless one of the y values is 2 and the other is 3. I.e. two CSI reports where collision occurs, one is a periodic CSI report and the other is a PUCCH based semi-persistent CSI report.

If one of the y values is 2 and the other is 3, the two reported CSI are multiplexed or discarded according to the priority value.

After the AI-based CSI feedback scheme appears, consider the situation of performing model performance monitoring on the Network (NW) side, since the UE needs to feedback a conventional high-precision conventional (legacy) CSI report as a baseline in addition to the AI-based CSI feedback, the coexistence problem of the two feedback needs to be considered. Specifically, there may be the following two problems:

Problem 1: when two CSI are reported using the same CSI-ReportConfigId, the PMI in this report should include two PMs calculated in two ways. The NW needs to distinguish the PMIs of the two CSI respectively so as to perform model monitoring;

problem 2: when two kinds of CSI are not reported using the same CSI-ReportConfigId, considering that there is a collision in reporting in the same time slot, the collision needs to be considered, which may involve the following two aspects:

in the first aspect, the time domain configuration type of both CSI may be a collision based on a type of PUCCH Periodic/semi Periodic (P/SP) P/SP;

in a second aspect, the time domain configuration types of both CSI may be P/SP based PUCCH and physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) aperiodic/semi-persistent (AP/SP) collision.

When both CSI are transmitted on the same CSI report, it may be as shown in fig. 1I. The legacy CSI report (report) and AI-based CSI report (report) t are reported in the same CSI-ReportConfigId #1, this reporting configuration being associated with the downlink resource CSI-ResourceConfigId # 1. The traditional CSI report (report) is calculated by a CSI Processing Unit (Processing Unit) of the UE from a channel state information-Reference Signal (CSI-RS) in CSI-resource econfigid # 1; AI-based CSI reporting (report) is calculated by the CSI generation model (generation model) at the UE side, and also by the CSI-RS in CSI-resource configid # 1.

For this CSI report, the content in the second portion of CSI would include two parts:

a second portion of CSI of the legacy CSI report;

the UE-side CSI generates the output of the model (i.e., AI-based CSI report).

Fig. 2 is an interactive schematic diagram illustrating a method for processing channel state information CSI according to an embodiment of the present disclosure. As shown in fig. 2, an embodiment of the present disclosure relates to a method for processing channel state information CSI, for use in a communication system 100. The communication system 100 may include a terminal and an access network device. The access network device may include base stations such as enbs and/or gnbs.

The method comprises the following steps:

s2101: and the terminal determines the sending behaviors of the at least two CSI according to the transmission relevance of the at least two CSI.

In some embodiments, the at least two CSI comprises: a first CSI and a second CSI.

In some embodiments, the first CSI is CSI generated based on Artificial Intelligence (AI) and/or Machine Learning (ML).

Illustratively, the first CSI may be the output of the CSI generating model as shown in fig. 1D.

In other embodiments, the second CSI is different from the first CSI. I.e. the second CSI is not CSI generated based on the AL model and/or the ML model. Illustratively, the first CSI may be CSI carried by AI-based CSI reports as shown in fig. 1I. Also illustratively, the second CSI may be CSI carried by a conventional CSI report as shown in fig. 1I.

The second CSI may be CSI obtained by the terminal based on CSI-RS measurement, for example.

In some embodiments, the sending behavior may be a behavior in which the terminal sends CSI. Illustratively, the act of transmitting may include: determining whether to transmit the first CSI and/or the second CSI, determining which part of the first CSI and/or the second CSI to transmit, and/or transmitting the first CSI and the second CSI specifically.

In some embodiments, the first CSI and the second CSI belong to different kinds of CSI.

In some embodiments, at least two CSI herein may include multiple CSI of the same type, or may be CSI of different types.

For example, the first CSI and the second CSI may be one or more.

In some embodiments, the specific content of the first CSI and the second CSI may be referred to in table 1, but it is noted that the specific content of the first CSI and the second CSI is not limited to table 1.

In some embodiments, the transmission association of at least two CSI may depend on the transmission configuration of the two CSI. The CSI is encapsulated or carried for transmission in CSI reports.

The transmission of different CSI may be determined by CSI reporting configuration (CSI-ReportConfig). The CSI-ReportConfig may determine a resource type, a resource amount, and/or a resource location, etc. of the CSI.

According to the physical channel corresponding to the resource, the resource type may at least include: PUCCH resources and/or PUSCH resources.

According to the time domain characteristics corresponding to the resource, the resource may at least include: periodic resources, semi-persistent resources, and/or aperiodic resources.

For example, aperiodic resources may also be referred to as dynamic resources, i.e., resources that can be dynamically scheduled through network signaling. For example, PUCCH resources and/or PUSCH resources for transmitting CSI are scheduled using downlink control information (Downlink Control Information, DCI).

The amount of resources may include: the number of time domain units and/or the number of frequency domain units.

Time domain units include, but are not limited to, minislots and/or symbols.

The frequency domain units may include, but are not limited to, resource Blocks (RBs) and/or Resource Elements (REs), etc.

That is, in some embodiments, the transmission behavior for at least another CSI is determined from the correlation between the transmission configurations of at least two CSI.

In some embodiments, the transmission association of the at least two CSI comprises at least one of:

whether the CSI reports of the at least two CSI are the same;

whether transmission resources of at least two CSI overlap in the time domain.

In some embodiments, at least two CSI, such as the first CSI and the second CSI, may be transmitted (or carried) by the same CSI report, i.e., the at least two CSI share one CSI report.

In other embodiments, the first CSI and the second CSI may be sent in different CSI reports.

Thus, in some cases, it is desirable to determine whether the first CSI and the second CSI are transmitted in the same CSI report.

In some cases, if the first CSI and the second CSI are transmitted in different CSI reports, the CSI configuration on the network side may select the same or different physical channels and/or time domain transmission behaviors, which are embodied in the time domain configuration type.

The time domain configuration types may include: periodic, semi-persistent, and/or aperiodic.

The time domain configuration type may include: periodic PUCCH, semi-persistent PUCCH, periodic PUSCH, semi-persistent PUSCH, and/or aperiodic PUSCH, and the like.

In some example embodiments, at least two CSI are configured to be transmitted on PUCCH resources and/or PUSCH, but the configured PUSCH resources and/or PUCCH resources may collide at specific locations in the time domain, e.g., the transmission resources of at least two CSI may be in the same time domain unit or may also be in different time domain units.

The time domain unit may include a slot, a minislot, a subframe, a radio frame, or the like. The specific time domain unit is not limited here.

In some embodiments, whether the physical uplink control channel resource PUCCH transmitting at least two CSI is located in the same time domain unit may at least include: whether the physical uplink control channel resource PUCCH transmitting at least two CSI is located in the same time slot or not.

In another embodiment, further, at least two CSI are configured to be sent on PUCCH resources and/or PUSCH, but the configured PUSCH resources and/or PUCCH resources are in specific positions in the time domain, not only may collision occur in the same time slot, but also whether there is overlap may be further determined.

In particular, the method is not limited to any of the above correlations, and the transmission behavior of at least two CSI may be determined, and whether to jointly transmit at least two CSI may be determined according to a transmission time interval and/or a transmission frequency domain interval of the two CSI. That is, the transmission association of at least two CSI is not limited to the above example.

In some embodiments, at least two CSI are transmitted via the same CSI report, determining to send a first CSI and a second CSI via one CSI report, wherein the first CSI and the second CSI share a first portion of the CSI report, and sequentially populating the first CSI and the second CSI to a second portion of the CSI report.

In the embodiment of the present disclosure, in order to reduce the resources that can be provided by the second portion of the CSI report configured by the network device because the first CSI and the second CSI need to be carried in the same CSI report at the same time, in the embodiment of the present disclosure, the first CSI and the second CSI are sequentially filled, so after the access network device on the network side receives the CSI report, it is known whether the currently decoded CSI belongs to the first CSI or the second CSI according to the decoding result, which is easy to distinguish.

In some embodiments, the modulation coding strategy MCS is determined according to the amount of resources of the second portion of the CSI report, the amount of data of the first CSI and the second CSI, and the amount of data before the first CSI and the second CSI are not encoded;

and writing the CSI to be transmitted to a second part of the CSI report according to a predetermined sequence of the first CSI and the second CSI filled into the CSI report.

For example, the first CSI and the second CSI may be sequentially padded into the CSI report directly without compressing the required amount of resources, which is smaller than the amount of resources of the second portion of the CSI report.

In some embodiments, the order in which the second portion of the CSI report is filled may be first CSI and then second CSI. The first CSI may be first and then the second CSI.

However, in either order, both the terminal and the access network device are aware, so that the access network device can obtain all the first CSI and the second CSI after decoding.

In some embodiments, the first CSI is preferentially padded to the second portion of the CSI report and the second CSI is refilled, so that it may be ensured that the first CSI is preferentially written to the CSI report.

In some embodiments, at least two CSI are transmitted via different CSI reports, and the transmitting behavior of the at least two CSI is determined according to the time domain configuration type of the at least two CSI transmissions.

In some embodiments, the at least two CSI are sent through different CSI reports, which may include that the first CSI and the second CSI are sent through different CSI, at which time the sending behavior of the at least two CSI may be determined according to the time domain configuration type of the at least two CSI transmission.

The time domain configuration type may include: periodic, aperiodic, and/or semi-persistent time domain configuration types.

In some embodiments, the sending behavior of the at least two CSI is determined based on whether the time domain configuration types of the at least two CSI transmissions are the same.

In some embodiments, in a case where the time domain configuration types of the at least two CSI transmissions are the same, the sending behavior of the at least two CSI may be determined further according to the time domain positions of the at least two CSI transmissions.

In other embodiments, in a case that the time domain configuration types of at least two CSI transmissions are different, it is determined to transmit various CSI or to jointly transmit at least two CSI, respectively, according to the time domain configuration types of at least two CSI transmissions.

In some embodiments, the time domain configuration type of the at least two CSI transmissions is periodic and/or semi-persistent PUCCH transmissions, and the transmitting behavior of the at least two CSI is determined according to whether PUCCHs transmitting the first CSI and the second CSI are located in the same slot.

In some embodiments, the PUCCH resources corresponding to periodic PUCCH transmissions are periodically distributed in the time domain. Semi-persistent PUCCH transmissions are also periodically distributed for any two PUCCH resources within a semi-persistent scheduled time range.

Thus, in some embodiments, if the time domain configuration type of at least two CSI transmissions is periodic and/or plate-persistent PUCCH transmissions, it is illustrated that there may be multiple PUCCH resources periodically distributed in the time domain for transmission of CSI reports. At this time, according to whether the first CSI and the second CSI specific PUCCH resources are located in the same slot, the transmitting behavior of at least two CSI is further determined.

In some embodiments, in the case that the PUCCH resource for transmitting the first CSI and the PUCCH resource for transmitting the second CSI are in the same time slot, the collision rule for multi-CSI transmission is satisfied, in this case, the transmission behaviors applicable to the first CSI and the second CSI are determined according to the fact that the PUCCH resources for transmitting the first CSI and the PUCCH resources for transmitting the second CSI are in the same time slot.

In some embodiments, the PUCCH resources transmitting the first CSI and the PUCCH resources transmitting the second CSI are configured as multiple CSI ucch resources. It can be appreciated that PUCCH resources transmitting the first CSI and PUCCH resources transmitting the second CSI are considered as multi-CSIPUCCH resources.

Typically, one multi-CSIPUCCH resource corresponds to multiple PUCCH resources.

In some embodiments, the PUCCH resources corresponding to the multiple CSIPUCCH resources may include, but are not limited to: PUCCH resources of the first CSI and PUCCH resources of the second CSI.

In some embodiments, the first CSI and the second CSI are based on periodic and/or persistent PUCCH resources, and the first CSI and the second CSI are located on the same slot, in which case, the PUCCH resources transmitting the first CSI and the PUCCH resources transmitting the second CSI are regarded as multiple CSI ucch resources, and then the rule of transmitting multiple CSI by the multiple CSI ucch resources needs to be satisfied.

In some embodiments, the PUCCH resources transmitting the first CSI and the PUCCH resources and transmitting the second CSI are configured as multiple CSI ucch resources, with the higher priority of transmitting the first CSI and the second CSI on one PUCCH resource of the multiple CSI ucch resources.

For example, among a plurality of PUCCH resources associated with one multi-CSI ucch resource, the PUCCH resource with the largest resource amount is selected for CSI transmission. And when one selected PUCCH resource cannot support all CSI transmission, the CSI with high priority can be prioritized.

For example, at this time the first CSI and the second CSI may be sent in CSI reports carried in the same or different, and sent on the same PUCCH resource.

For example, when the PUCCH resource with the largest amount of resources among the plurality of PUCCH resources associated with one multi-CSI ucch resource is enough to carry the data amounts of the first CSI and the second CSI, both the first CSI and the second CSI may be transmitted on the PUCCH resource. At this time, the first CSI and the second CSI may be transmitted on the PUCCH resource in a predetermined order. Or, simultaneously sending the first CSI and the second CSI on the PUCCH resource, and respectively sending identifiers of the first CSI and the second CSI, so as to facilitate the access network device to distinguish the two CSI transmitted on the same PUCCH resource.

In some embodiments, when there is no PUCCH resource that can carry the first CSI and the second CSI in the multiple PUCCH resources associated with one multiple CSIPUCCH resource, it is necessary to select to send CSI with high priority according to the priority of the first CSI and the second CSI, and discard CSI with low priority, or send CSI with low priority on the next PUCCH resource.

In some embodiments, the PUCCH resource for transmitting the first CSI and the PUCCH resource for transmitting the second CSI are in the same time slot, and the collision rule for multi-CSI transmission is satisfied no matter whether the PUCCH resource for transmitting the first CSI and the PUCCH resource for transmitting the second CSI overlap in time domain, in which case, the transmission behaviors applicable to the first CSI and the second CSI are determined according to the fact that the PUCCH resource for transmitting the first CSI and the PUCCH resource for transmitting the second CSI are in the same time slot. That is, in the case that the PUCCH resource for transmitting the first CSI and the PUCCH resource for transmitting the second CSI are in the same time slot, and the PUCCH resource for transmitting the first CSI and the PUCCH resource for transmitting the second CSI are overlapped or not overlapped in the time domain, it may be determined that the CSI with the high priority is preferentially transmitted on one PUCCH resource on the corresponding multi-CSI ucch resource according to the fact that the PUCCH resource for transmitting the first CSI and the PUCCH resource for transmitting the second CSI are in the same time slot.

In some embodiments, the priority of the first CSI and the second CSI may be specified by a protocol convention or a network device.

Illustratively, the priority of the first CSI is higher than the priority of the second CSI, etc.

In some embodiments, the priorities of the first CSI and the second CSI are determined using the same functional relationship;

or,

In some embodiments, the priorities of the first CSI and the second CSI are calculated using a functional relationship, and no protocol conventions are required, nor network side designations are required. Without protocol conventions, the priorities of the first CSI and the second CSI may be dynamically adjusted instead of fixed. No indication by network equipment is needed, no signaling is consumed, and signaling overhead is saved.

In some embodiments, the first CSI and the second CSI are different types of CSI, and thus the parameters of the CSI are different, the same functional relationship may be used, and different priorities may be calculated. If the same functional relationship is used to calculate the priorities of the first CSI and the second CSI respectively, the terminal and the access network device only need to maintain one functional relationship.

In other embodiments, because the first CSI and the second CSI are different types of CSI, different functional relationships may be used to calculate the priorities, so that the priority calculation of the first CSI and the second CSI may be separated according to the need, and flexibility of priority setting of the first CSI and the second CSI is improved.

In some embodiments, using the same functional relationship, determining the priority of the first CSI and the second CSI comprises:

Pri _iCSI (y,k,c,s)＝2·N _cells ·M _s ·y+N _cells ·M _s ·k+M _s c+s (functional relation 1);

wherein, for aperiodic first CSI of PUSCH transmission, y=0;

for the semi-persistent first CSI of PUSCH transmission, then y=1;

for the semi-persistent first CSI of PUCCH transmission, then y=2;

for the first CSI of the period of PUCCH transmission, then y=3;

for aperiodic second CSI of PUSCH transmission, y=4;

a second CSI for PUSCH transmission semi-persistent, then y=5;

for the second CSI of the period of PUCCH transmission, then y=7;

c represents a serving cell index;

N _cells is the number maxNrofServingCells of the maximum serving cell;

s is the value of report configuration identification reportConfigID;

M _s Is the CSI report configuration maximum maxNrofCSI-ReportConfigurations;

Pri _iCSI representing priority, pri _iCSI Is inversely related to the priority level

Of course, the above is merely an example of calculating the first CSI and the second CSI using the same functional relationship, and the specific implementation is not limited to the above example.

In some cases, the above functional relationship 1 may introduce one or more coefficients, and/or one or more bias values.

In other embodiments, using different functional relationships to determine the priority of the first CSI and the second CSI, respectively, includes:

determining the priority of the second CSI by adopting the following function;

Pri _iCSI (y ₁ ,y ₂ ,k,c,s)＝3·N _cells ·M _s ·y ₁ +2·N _cells ·M _s ·y ₂ +N _cells ·M _s ·k+M _s c+s (functional relationship 2);

wherein, for aperiodic first CSI of PUSCH transmission, y=0;

for the semi-persistent first CSI of PUSCH transmission, then y=1;

for the semi-persistent first CSI of PUCCH transmission, then y=2;

for the first CSI of the period of PUCCH transmission, then y=3;

for aperiodic second CSI of PUSCH transmission, y=4;

c represents a serving cell index;

N _cells is the maximum number of serving cells (maxNrofServingCells);

s is the value of the report configuration identity (reportConfigID);

M _s is CSI report configuration maximum (maxNrofCSI-ReportConfigurations);

In some embodiments, using different functional relationships to determine the priority of the first CSI and the second CSI, respectively, includes:

determining the priority of the second CSI by adopting the following function;

Pri _iCSI (y,k,c,s)＝2·N _cells ·M _s ·y+N _cells ·M _s ·k+M _s c+s (functional relation 3);

for aperiodic second CSI of PUSCH transmission, y=0;

a second CSI for PUSCH transmission semi-persistent, then y=1;

a second CSI for half-duration of PUCCH transmission, then y=2;

for the second CSI of the period of PUCCH transmission, then y=3;

c represents a serving cell index;

N _cells is the maximum number maxNrofServingCells of the serving cell;

s is the value of report configuration identification reportConfigID;

M _s is the CSI report configuration maximum maxNrofCSI-ReportConfigurations;

It can be seen that the priorities of the first CSI and the second CSI are calculated using the functional relation 2 and the functional relation 3, respectively.

Of course, the above embodiments are specific implementations of calculating priorities, and the specific implementations are not limited to the above examples.

In other embodiments, determining the transmission behavior of at least two CSI according to whether PUCCH resources transmitting the first CSI and the second CSI are located in the same slot includes:

The first CSI and the second CSI transmitted jointly may have at least one of the following characteristics:

the first CSI and the second CSI may use MCSs;

the first CSI and the second CSI are not limited to one PUCCH resource transmission, e.g., a portion of PUCCH resources of the first CSI may be used to transmit the second CSI; for another example, part of the content of the first CSI may be transmitted on the PUCCH resource of the second CSI, so that when one CSI of the first CSI and the second CSI does not need to occupy one PUCCH resource, the remaining PUCCH resource may be used for transmission of the other CSI.

In one embodiment, jointly transmitting the first CSI and the second CSI includes:

CSI is transmitted on two PUCCH resources.

In some embodiments, the first CSI and the second CSI are modulated and encoded by using the same MCI, so that the first CSI and the second CSI can be sent to the network side through the respective corresponding CSI as much as possible.

In some embodiments, the time domain configuration types of the at least two CSI transmissions include: and determining the sending behaviors of at least two CSI according to whether the PUCCH transmission and the PUSCH transmission are overlapped in time domain or not.

In some embodiments, PUCCH and PUSCH are used to transmit different CSI of the at least two CSI, respectively.

When one of the transmission resources of the first CSI and the second CSI is the PUCCH resource and the other is the PUSCH resource, the transmission behavior for the first CSI and the second CSI is determined according to whether the transmission resources overlap in the time domain.

In some embodiments, the PUCCH resources and PUSCH resources for transmitting the first CSI and the second CSI overlap in the time domain, where one case discards the CSI transmitted by the PUCCH, and another case may transfer the CSI transmitted by the PUCCH onto the PUSCH for transmission. If the CSI transmitted by the PUCCH resource is transferred to the PUCSH for transmission, the access network device may also receive two CSI, i.e., the first CSI and the second CSI.

In other embodiments, the second portion of the CSI report of the PUCCH transmission is transferred to the PUCSH for transmission.

In some embodiments, if the two PUCCH resources overlap in time domain, the first CSI and the second CSI may be continuously transmitted using the two PUCCH resources in combination according to whether the two PUCCH resources overlap in frequency domain or not, and if the two PUCCH resources do not overlap in frequency domain.

In still other embodiments, if two PUCCH resources overlap in time domain and overlap in frequency domain, the CSI of high priority may be preferentially transmitted according to priorities of the first CSI and the second CSI.

The priorities of the first CSI and the second CSI may be defined by a protocol convention, specified by the network device, or calculated using any one of the foregoing functional relationships 1, 2, and 3.

In the case of joint transmission of the first CSI and the second CSI, in order to facilitate the access network device to distinguish the first CSI from the second CSI, a separator is provided between the first CSI and the second CSI.

In some embodiments, the PUCCH transmission and the PUCSH transmission overlap in the time domain, determining to transfer a second portion of a third CSI of the PUCCH transmission to the PUCSH transmission; wherein, the tri-CSI is the first CSI or the second CSI.

At this time, the first CSI and the second CSI may share the same first portion of CSI report, which saves resources on the one hand, saves signaling overhead on the other hand, and may further enable the access network device to receive the complete first CSI and the complete second CSI on the other hand.

The network device may configure one or more PUCSH resources for the terminal, and the transmission content of a specific PUCSH resource may be freely controllable by the terminal within a network device configuration specification type.

In some embodiments, the third CSI may be calculated in a plurality of ways, and examples are provided below, and the embodiments are not limited to these examples.

In some embodiments, the third CSI is the first CSI, and the fourth SCI is the second CSI; and the third CSI is the second CSI, and the fourth CSI is the first CSI.

In some embodiments, any relevant technique may be used to calculate the PUSCH resources of the first CSI or the second CSI, and if twice the pucch resources are directly used, the PUSCH resources are directly multiplied by 2 after the amount of the pucch resources required for the first CSI or the second CSI that is originally configured to be transmitted using the PUSCH is calculated. At this time, the access network device receives the CSI transmitted by the PUCSH, and directly determines, according to the state of the resource pair half, which of the decoded information belongs to the first CSI and which of the decoded information belongs to the second CSI.

S2102: and the terminal transmits the CSI according to the determined transmission behavior.

In some embodiments, according to determining the sending behavior of at least two CSI, CSI is sent on PUCCH resources and/or PUSCH resources corresponding to CSI.

In some embodiments, according to determining the sending behavior of at least two CSI, the first CSI and/or the second CSI are sent on PUCCH resources and/or PUSCH resources corresponding to the CSI.

S2103: the access network equipment determines the receiving behaviors aiming at least two CSI according to the transmission relevance of the at least two CSI; the at least two CSI includes: a first CSI and a second CSI; wherein the first CSI is CSI generated based on artificial intelligence and/or machine learning; the second CSI is different from the first CSI.

In some embodiments, the access network device configures the CSI reporting configuration of each CSI for the terminal, and then the access network device itself knows each CSI reporting configuration, so that the receiving behavior for at least two CSI can be determined according to the transmission association of at least two CSI.

In some embodiments, when determining the sending behavior of at least two CSI, the terminal determines according to a protocol convention, the access network device will also know the protocol convention, so that the access network device can determine the receiving behavior for at least two CSI according to the transmission association of two CSI described by the protocol convention, in a manner known together with the terminal.

Here, the receiving behavior of the access network device for at least two CSI is the same as the transmitting behavior of the terminal for at least two CSI.

In this common embodiment, the manner in which the access network device determines the receiving behavior for at least two CSI may be referred to in step S2101, and the detailed description will not be repeated here.

In some embodiments, the terminal performs a determined transmit behavior, and the base station performs a determined receive behavior.

On the one hand, the method for processing the CSI can solve the problem that the content of the CSI reported to the base station is lacking due to insufficient configured resources when two CSI are sent by using the same CSI report. For example, in this way, it may be possible for both the first CSI and the second CSI to be reported to the value access network device.

On the other hand, if at least two CSI are transmitted using different CSI reports, appropriate transmitting and receiving behaviors of at least two CSI are selected according to whether the resources for transmitting at least two CSI collide or not and further according to the transmission association, so as to realize flexible reception of CSI and the like.

Notably, are: s2101 and S2103 may not have a certain order, for example, S2101 and S2103 may be executed synchronously, or S2101 may be executed first and S2103 may be executed second, or S2103 may be executed first and S2101 may be executed second.

If the access network device executes S2103, S2101 and S2103 may be provided before S2102.

In some embodiments, the access network device may not perform S2103, and the access network device may passively receive CSI sent by the terminal on the corresponding resource, and the specific received CSI type and the like may be determined according to decoding the received data.

Fig. 3 is an interaction diagram illustrating a method for processing channel state information CSI according to an embodiment of the present disclosure. As shown in fig. 3, an embodiment of the present disclosure relates to a method for processing channel state information CSI, for a terminal. The terminal may also be referred to as a User Equipment (UE).

As shown in fig. 4, an embodiment of the present disclosure relates to a method for processing channel state information CSI, which is used for an access network device. Including but not limited to various base stations or access points.

In the present public embodiment, the specific execution of S4101 can be referred to S2103 of the corresponding embodiment of fig. 2.

In some embodiments, the method may further comprise:

s3102, performing the determined transmission behavior.

In some embodiments, when two CSI are transmitted on the same CSI report, as shown in fig. 1I.

As shown in fig. 1I and 5A, both CSI are transmitted on the same CSI report.

At this time, the contents in the conventional CSI report and the AI-based CSI report CSI part 2 may include two parts:

CSI part 2 of the legacy CSI report;

the output of the UE side CSI generation model (AI-based CSI report).

At this time, in order to better perform the differentiation of the two-part CSI part 2, allocation may be made such that solution 1 for problem 1 is as follows:

since the bit number of AI-based CSI report is determined, in order for the NW side to be able to distinguish the two parts of content in CSI part 2, the following allocation may be made as shown in fig. 5A.

The number of bits of the AI-based CSI report is relatively determined, for example, once the AI model or the ML model is determined, the number of bits used by the output of the AI/ML model.

In this way, even if the number of PUCCH resources allocated to CSI part 2 is smaller than the enhanced part 2 bit stream to be transmitted in fig. 5A, the two parts of CSI part 2 contents to be transmitted jointly perform operations such as channel coding and rate matching existing in the existing standard, and are transmitted in limited PUCCH resources after being affected by the same level of error code. After the channel is passed, the CSI part 2 bit stream recovered at the gNB end can still distinguish two parts of part 2 content, and network side model monitoring is carried out according to the two parts of part 2 content.

In some embodiments, when two CSI are transmitted on different reports, the following two cases can be separated:

the time domain behaviors of the two CSI are P/SP on PUCCH;

the time domain behaviors of the two CSI are P/SP on PUCCH and AP/SP on PUSCH respectively.

The two cases will be separately elucidated and corresponding solutions are proposed.

In some embodiments of the present invention, in some embodiments,

for the case that two kinds of CSI are transmitted on different reports and the time domain behaviors are P/SP on PUCCH, if the PUCCH resources corresponding to the two CSI reports are not transmitted on the same time slot, namely, collision does not occur on the same time slot, no influence is exerted on the existing standard.

Therefore, mainly consider the case where two CSI reports whose time domain behaviors are P/SP on PUCCH are configured to be transmitted on the same slot and the periods are different, as follows. In this case, two CSI reports occur with multi-CSI collision. As shown in the figure IE, CSI-ReportConfigId #1 transmitting the legacy CSI and CSI-ReportConfigId #2 transmitting the AI-based CSI are transmitted on the same slot, which are associated with PUCCH-resource id #1 and PUCCH-resource id #2, respectively.

In this case, both CSI bearers are transmitted on the same PUCCH slot.

At this time, consider the RRC signaling configuration of the CSI report, and the PUCCH configuration carrying this CSI report, as shown in fig. 5B.

Fig. 5B shows the association of CSI-ReportConfig and PUCCH-CSI-Resource. In fig. 5B, PUCCH resources corresponding to two CSI reports transmitted using two PUCCH resources of the same slot are configured as multiple CSI ucch resources, and finally transmitted on one PUCCH resource among the multiple CSI PUCCH resources.

Thus, for the case where two CSI reports are configured on the same time slot, there may be the following solutions:

one multi-CSI ucch resource is configured to be associated with PUCCH resources corresponding to the two CSI-ReportConfigId.

That is, PUCCH-resourceid#1 and PUCCH-resourceid#2 must be included in the multi-CSI-PUCCH-ResourceList as shown in fig. 5C.

And when the CSI resources required to be transmitted exceed the bearing capacity of the multi-CSI UCCH resources, whether the CSI resources are required to be selected or not according to the priority of the CSI is ensured, so that the two CSI reports can be completely reported in the same PUCCH (PUCCH with larger bearing capacity).

In view of this, two ways are presented for CSI transmission. One is to transmit CSI with high priority preferentially based on priority, and the other is to perform joint transmission of two kinds of CSI.

Option 1: consider the priority design of CSI reporting after adding AI-based CSI report.

Option 1-1: the priority formula design in the existing standard is reused, but the y value reported by the CSI based on the AI is newly added.

Wherein:

y=0 is used for aperiodic AI-based CSI reporting carried on PUSCH, y=1 is used for semi-static AI-based CSI reporting carried on PUSCH, y=2 is used for semi-static AI-based CSI reporting carried on PUCCH, and y=3 is used for periodic AI-based CSI reporting carried on PUCCH;

y=4 is used for aperiodic CSI reporting carried on PUSCH, y=5 is used for semi-static CSI reporting carried on PUSCH, y=6 is used for semi-static CSI reporting carried on PUCCH and y=7 is used for periodic CSI reporting carried on PUCCH.

k=0 represents CSI reporting carrying L1-RSRP, k=1 represents CSI reporting not carrying L1-RSRP;

c represents a serving cell index;

N _cells is the value of the higher layer parameter maxNrofServingCells;

s is the value of the higher layer parameter reportConfigID;

M _s is the value of the higher layer parameter maxNrofCSI-ReportConfigurations;

Option 1-2: considering AI-based CSI reporting, the priority formula in the existing standard is extended as follows.

Pri _iCSI (y ₁ ，y ₂ ，k，c，s)＝3·N _cells ·M _s ·y ₁ +2·N _cells ·M _s ·y ₂ +N _cells ·M _s ·k+M _s ·c+s

Wherein:

y ₁ =0 for aperiodic AI-based CSI reporting carried on PUSCH, y ₁ =1 semi-static AI-based CSI reporting for bearers on PUSCH, y ₁ =2 semi-static AI-based CSI reporting for bearers on PUCCH, y ₁ =3 for periodic AI-based CSI reporting carried on PUCCH;

y ₂ =0 for aperiodic CSI reporting carried on PUSCH, y ₂ =1 semi-static CSI reporting for PUSCH bearers, y ₂ =2 semi-static CSI reporting for PUCCH bearers and y ₂ =3 for periodic CSI reporting carried on PUCCH.

c represents a serving cell index;

N _cells is the value of the higher layer parameter maxNrofServingCells;

s is the value of the higher layer parameter reportConfigID;

Option 2: when two PUCCH resources are transmitted only on the same slot and there is no collision of time-frequency resources: when the configured multi-CSIUCCH resources are fully utilized and multi-CSI conflicts generated in the existing standard are changed, the conflicting multiple CSI are limited to be transmitted on the same multi-CSI UCCH, and when the configured multi-CSI UCCH resources are insufficient for transmitting two CSI reports, at most two multi-CSI UCCHs can be combined for common transmission, so that all CSI contents are reported.

Fig. 5D is a flow chart for joint transmission of multiple CSI for multiple CSI ucchs. The union of the embodiments to be written is understood as common.

Wherein, the union may represent: if the first PUCCH resource is not enough to transmit the corresponding CSI report, but the second resource is rich, a portion beyond which the second Multi-CSI ucch resource is transmitted may be selected; of course, this is merely an example and does not exclude other possibilities.

In some cases, simultaneous transmission of CSI by PUCCH and PUSCH is not supported, and thus, when transmission times of both overlap, one channel transmission needs to be selected.

When two CSI are transmitted on different CSI reports and the time domain behaviors are P/SP on PUCCH and AP/SP on PUSCH, respectively, there are different combinations of the time domain behaviors of the two CSI as follows:

the time domain behavior of the CSI based on the AI is P/SP on PUCCH, and the time domain behavior of the traditional CSI is AP/SP on PUSCH;

the time domain behavior of the CSI based on AI is AP/SP on PUSCH, and the time domain behavior of the traditional CSI is P/SP on PUCCH.

However, since the collision problem is considered, that is, when PUCCH and PUSCH resources are completely or partially overlapped in the time domain, the problems and solutions of the two cases are the same, and thus, they will not be distinguished in the following.

As shown in fig. 5E, in the case of collision between the PUCCH and the single-slot PUSCH, when CSI transmission exists in both the PUSCH and the PUCCH, HARQ/ACK carried in the PUCCH needs to be transferred to PUSCH for transmission, and CSI in the PUCCH is discarded, so that redundant transmission of CSI is avoided.

Considering AI-based CSI reporting, it is necessary to avoid discarding important information such as PMI, so as to support model monitoring on NW side, and as shown in fig. 5F, enhance PUCCH and PUSCH collision resolution, and transfer at least the second part of CSI report of PUCCH transmission to PUSCH for transmission. At this time, the calculation of the resource amount of PUSCH is re-involved. More specifically, there are two options and corresponding uplink resource calculation modes:

option 1: and calculating the required part 2 CSI' according to the part 1CSI information in the PUSCH, and adding the part 2 CSI transmitted on the PUCCH to the back of the PUSCH part 2 CSI.

The part 2 CSI' at this time includes part 2 CSI which should be transmitted on the PUSCH and part 2 CSI which should be transmitted on the PUCCH;

and calculating the uplink resource required by the part 2 CSI' according to the following scheme, wherein the required uplink resource is twice the uplink resource required by the part 2 CSI in the existing standard. According to the calculation of the uplink resources required by the part 2 CSI in the existing standard, the calculation of the part 2 CSI' can be divided into the following cases:

For CSI part 2 transmission on PUSCH without repetition type B with UL-SCH, and if higher layer parameter number of slotstboms is not present in the resource allocation table, or if higher layer parameter number of slotstboms is present in the resource allocation table and the value of number of slotstboms indicated by the time domain resource allocation field of DCI is 1, the number of coded modulation symbols per layer for part 2 CSI' transmission is determined as follows:

If the number of information bits of HARQ-ACK is 1 or 2, Q' _ACK ＝0；

If both HARQ-ACK and CG-UCI exist on the same PUSCH with UL-SCH, Q' _ACK/CG-UCI ＝Q′ _ACK And: q'. _ACK The number of modulation symbols is coded for each layer for HARQ-ACK and CG-UCI transmitted on PUSCH.

At this time, since the number of resources required is added, the number of resources actually used for PUSCH UCI transmission as a whole becomes large

Option 2: and synthesizing part 2 CSI information carried in the PUSCH and the PUCCH, calculating required uplink resources, adding the part 2 CSI transmitted on the PUCCH to the rear of the PUSCH part 2 CSI, and adding an indicating bit between the original PUSCH part 2 CSI and the original PUSCH part 2 CSI in order to indicate the demarcation of the two part 2 CSI.

The new CSI part 2 in this option requires no more than 2 times the original resources, reducing the uplink overhead of the transmission in this collision situation.

Mode 2: at this time, the uplink resources required for the part 2 CSI' are calculated as follows.

Representing the number of bits required for part 2 CSI transmitted on PUCCH;

the number of bits required for the original PUSCH part 2 CSI is represented. Other parameters are referred to in the corresponding embodiments described above.

Option 1: for PUSCH without UL-SCH repetition type B, if there is a numberOfSlotsTBoMS in the resource allocation table and the value of numberOfSlotsTBoMS indicated by the time domain resource allocation field in the DCI is greater than 1, the number of coded modulation symbols per layer for part 2 CSI' transmission is determined as follows:
