technical field

The present application belongs to the technical field of wireless communication, and specifically relates to a method, device and terminal for determining the number of occupied CSI processing units (CSI Processing Unit, CPU) reported by Channel State Information (CSI).

Background technique

Coordinated Multiple Points (CoMP) transmission refers to multiple geographically separated transmission points that cooperate to participate in data transmission for a terminal or jointly receive data sent by a terminal. Multiple transmission points participating in cooperation usually refer to Base stations in different cells. The cooperation of multiple cell base stations can use the interference signal as a useful signal, thereby reducing the interference between cells and improving the spectrum utilization rate of the system.

Each of the common CoMP schemes can be classified into one of the following categories: Joint Processing (JP) or Coordinated Scheduling (CS)/Coordinated Beamforming (CB).

Among them, joint processing (JP) means that the data of a user terminal (User Equipment, UE) is available on more than one time-frequency resource point in the CoMP cooperation set, including:

(1) Joint Transmission (JT). For example, data is simultaneously transmitted from multiple points (a part of the CoMP cooperating set or the entire CoMP cooperating set) to one UE or multiple UEs in one time-frequency resource. Alternatively, data is transmitted to the UE simultaneously from multiple points, eg, to improve received signal quality and/or data throughput (coherently or non-coherently).

(2) Dynamic point selection (DPS)/FM. Data transmission occurs from one point (within a CoMP cooperating set) in one time-frequency resource. The transmission/mixing point can be changed from one subframe to another, including the change on the radio bearer (Radio Bearer, RB) pair within a subframe. Data is available at multiple points simultaneously. Dynamic site selection/FM can include dynamic cell selection (Dynamic cell selection, DCS).

(3) The combination of DPS and JT. In this case, multiple points can be selected in the time-frequency resource for data transmission. Coordinated Scheduling/Beamforming (CS/CB) means that for a time-frequency resource, UE data is only available at one point in the CoMP cooperating set and transmitted from that point (Downlink, DL) data transmission from that point on), but user scheduling/beamforming decisions are coordinated between points corresponding to the CoMP cooperating set. The selection of the transmission point is semi-static, that is, semi-static point selection (SSPS), that is, each time a transmission is made from a point to a specific UE, the transmission point can only be changed in a semi-static manner.

The current Multiple Transmission Reception Point (MTRP) transmission is generally non-coherent joint transmission (Non-Coherent Joint Transmission, NCJT), that is, each transmission reception point (Transmission Reception Point, TRP) sends an independent layer (layer ), therefore, the network configures one or more pairs of Channel Measurement Resource (CMR) pairs for the terminal, and the terminal calculates NCJT CSI based on the CMR pair and feeds back, for example, 2 TRPs feed back 2 precoding matrix indications (Precoding matrix indicator, PMI), 2 rank indicators (Rank indicator, RI), 1 channel quality indicator (Channel quality indicator, CQI), etc.

Each terminal has its ability to process CSI reports, that is, the number N _CPUs of simultaneous calculation of CSI is supported. If a terminal supports N _CPUs of simultaneous CSI calculations, the UE supports up to N _CPUs of CPUs for processing CSI reports of all configured cells . Therefore, before updating the CSI report, the terminal needs to determine the number of CPUs required to update the CSI report (that is, the number of CPUs occupied by the CSI report) to determine whether the number of CPUs exceeds the number of CPUs available to the terminal. However, the current method for determining the number of CPU occupations reported by CSI is only applicable to the CSI transmitted by a single TRP and the CSI transmitted by non-coherent cooperative transmission of two TRPs, but not applicable to the CSI transmitted by multiple TRPs.

In this embodiment of the present application, the CSI reporting setting (CSI reporting setting) may be configured by the network side device to the terminal through high-layer signaling CSI-Report Config.

In a possible implementation manner, the CPU usage quantity includes at least one of the following:

(1) n times the first quantity, wherein n is an integer greater than 0.

For example, the network side device configures a CSI report setting for the terminal, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set to obtain coherent joint transmission CSI, Then the terminal determines that the number of CPUs occupied by the first CSI report (the CSI report including the coherent joint transmission CSI) configured by the CSI report setting is 4.

It should be noted that although n=1 in the above example, it is not limited thereto. In practical applications, n may also take other integers greater than 0, which are not limited in this embodiment of the present application.

(2) 1/m times the second number, wherein m is an integer greater than 0.

For example, the network-side device configures a CSI report setting for the terminal. The CSI report setting is associated with a channel measurement resource set. A CMR with 32 ports is configured in the channel measurement resource set to obtain coherent transmission CSI. By default, the terminal measures 8-port channels If one CPU needs to be occupied, the terminal determines that the number of CPUs occupied by the first CSI report configured in the CSI report setting is 4.

For another example, the network side device configures a CSI report setting for the terminal, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR (used to obtain coherent joint transmission CSI) and a 16-port CMR are configured in the channel measurement resource set. Port CMR (used to obtain Single-TRP transmission CSI). By default, the terminal needs to occupy 1 CPU for measuring 8-port channels, and the terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting is 4.

For another example, the network side device configures a CSI report setting for the terminal. The CSI report setting is associated with a channel measurement resource set. A CMR with 16 ports is configured in the channel measurement resource set to obtain CSI for coherent joint transmission. The terminal measures 16 by default. If the port channel needs to occupy 1 CPU, the terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting is 1.

It should be noted that although m is 8 and 16 in the above examples, it is not limited thereto. In practical applications, m can also take other integers greater than 0, which are not limited in the specific embodiments of the present application.

(3) k times the third quantity, wherein k is an integer greater than 0.

For example, the network side device configures a CSI report setting for the terminal, and the CSI report setting is associated with a channel measurement resource set, and 4 CMR groups (each CMR group includes a CMR) are configured in the channel measurement resource set to obtain coherent joint When transmitting CSI, the terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting is 4.

It should be noted that although k=1 in the above example, it is not limited to this, and in actual application In use, k may also take other integers greater than 0, which are not specifically limited in the embodiments of the present application.

(4) s times the fourth quantity, wherein s is an integer greater than 0.

For example, the network-side device configures a CSI report setting for the terminal. The CSI report setting is associated or configured with 4 coherent joint transmission measurement hypotheses. The terminal measures the 4 measurement hypotheses to obtain 4 CSIs, and selects the optimal CSI for feedback. Then The terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting is 4.

It should be noted that although in the above example, s=1, it is not limited thereto. In practical applications, s may also take other integers greater than 0, which are not limited in this embodiment of the present application.

(5) p times the fifth quantity, wherein p is an integer greater than 0.

For example, the network side device configures a CSI report setting for the terminal, and the CSI report setting association or configured measurement hypothesis includes a Single-TRP transmission measurement hypothesis, which corresponds to a CMR measurement resource, and the terminal measures the non-coherent coordinated transmission If the measurement occupies 1 CPU, the terminal determines that the CPU occupied by the first CSI report configured by the CSI report setting includes 1 CPU.

For another example, the network side device configures a CSI report setting for the terminal, and the CSI report setting association or configured measurement hypothesis includes an NCJT transmission measurement hypothesis, and the measurement hypothesis corresponds to 2 CMR measurement resources or 1 CMR measurement resource pair, The terminal measures that the non-coherent coordinated transmission measurement occupies 2 CPUs, and then the terminal determines that the first CSI report configured by the CSI report setting configuration occupies 2 CPUs.

In an actual application, the CPU occupation amount reported by the first CSI may be one of the above items, or a combination of multiple items thereof.

For example, the network-side device configures a CSI report setting for the terminal. The CSI report setting is associated or configured with a coherent joint transmission measurement hypothesis and a Single-TRP transmission measurement hypothesis. The coherent joint transmission measurement hypothesis corresponds to a CMR measurement resource. The CMR If the resource is configured with 4 CMR port groups, it needs to occupy 4 CPU resources. For the non-coherent transmission measurement assumption, the measurement assumption corresponds to a CMR measurement resource and occupies 1 CPU resource. In summary, the terminal determines the CSI report setting The number of CPUs occupied by the configured first CSI report is 5.

For another example, the network side device configures a CSI report setting for the terminal. The CSI report setting is associated or configured with a coherent joint transmission measurement hypothesis and an NCJT transmission measurement hypothesis. The coherent joint transmission measurement hypothesis corresponds to a CMR measurement resource. The CMR resource If 4 CMR port groups are configured, 4 CPU resources are required. For NCJT transmission The measurement assumption corresponds to one CMR measurement resource pair and occupies 2 CPU resources. In summary, the terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting is 6.

For another example, the network side device configures a CSI report setting for the terminal, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set (for obtaining coherent joint transmission CSI) and a 16-port CMR with 1 port group (used to obtain non-coherent joint transmission CSI), the terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting is 5.

In a possible implementation manner, the CPU usage number may also be t times the sixth number, where t is an integer greater than 0, and the sixth number is a measurement assumption associated or configured in the CSI report setting The sum of the number of CPUs occupied by multiple measurement assumptions in .

In the above possible implementation manner, optionally, the multiple measurement assumptions include a first measurement assumption and a second measurement assumption; wherein, the number of CPUs occupied by the first measurement assumption is the channel measurement corresponding to the first measurement assumption N times the number of resources; and/or, the number of CPUs occupied by the second measurement hypothesis is one of the following: M1 times the number of channel measurement resources corresponding to the second measurement hypothesis, the channel corresponding to the second measurement hypothesis M2 times the number of port groups of measurement resources, and 1/M3 times the number of ports of channel measurement resources corresponding to the second measurement assumption; wherein, N, M1, M2, and M3 are integers greater than 0, and the first measurement The assumption is a non-coherent cooperative transmission measurement hypothesis in the associated or configured measurement assumptions in the CSI report setting, and the second measurement hypothesis is a coherent coordinated transmission measurement assumption in the associated or configured measurement assumptions in the CSI report setting.

For example, the network-side device configures a CSI report setting for the terminal. The CSI report setting is associated or configured with 1 coherent coordinated transmission measurement hypothesis and 1 non-coherent coordinated transmission measurement hypothesis. The coherent coordinated transmission measurement hypothesis corresponds to 1 CMR measurement resource. , the CMR resource is configured with 16 port CMRs. By default, the terminal needs to occupy 1 CPU to measure 8-port channels, so the coherent cooperative transmission measurement assumption needs to occupy 2 CPU resources. For the non-coherent transmission measurement assumption, the measurement assumption corresponds to a The CMR measurement resource occupies 1 CPU resource. In summary, the terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting is (2+1)*2, that is, 6 CPUs.

For example, the network-side device configures a CSI report setting for the terminal. The CSI report setting is associated or configured with 1 coherent coordinated transmission measurement hypothesis and 1 non-coherent coordinated transmission measurement hypothesis. The coherent coordinated transmission measurement hypothesis corresponds to 1 CMR measurement resource. , the CMR resource There are 16 port CMRs configured, with a total of 4 CMR port groups. The coherent cooperative transmission measurement assumption needs to occupy 4 CPU resources. For the non-coherent transmission measurement assumption, the measurement assumption corresponds to a CMR measurement resource pair and occupies 2 CPU resources. In summary, the terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting is 2+4, that is, 6 CPUs.

In this embodiment of the present application, after S210, the terminal may update the CSI according to the number of CPUs occupied by the terminal and the number of unoccupied CPUs of the terminal.

In a possible implementation, when updating the CSI, when the number of unoccupied CPUs of the terminal is less than the number of CPUs occupied and greater than or equal to 1, the terminal uses the unoccupied The CPU updates part of the CSI in the first CSI report. Through this possible implementation manner, when the number of CPUs available to the terminal is not enough, the terminal can only calculate part of the CSI, thereby maximizing the use of resources and avoiding waste of resources.

Wherein, the number of unoccupied CPUs of the terminal (that is, the number of CPUs available to the terminal) may be based on the number of N_CPUs that the terminal supports to simultaneously calculate CSI and the CPUs that are occupied to process CSI reports on a certain OFDM symbol Quantity determines the number of possible CPUs for the endpoint. For example, in a certain OFDM symbol, if L CPUs are already occupied to process the CSI report, the UE still has N_CPU-L available CPUs. In the above implementation, if in S210, the number of CPUs occupied by the terminal O_CPU^((n)) is greater than N_CPU-L, and N_CPU-L is greater than or equal to 1, then the terminal uses the available N_CPU-L CPUs to update Part of the CSI in the first CSI report. For example, the terminal may update part of the CSI in the first CSI report according to the order of CSI in the CSI report setting, or the terminal may also determine which part of the first CSI report to update according to the CPU mathematics occupied by the CSI in the first CSI report. Part of CSI.

For example, the network-side device configures a CSI report setting for the terminal. The CSI report setting is associated with or configured with one coherent transmission measurement hypothesis and one non-coherent transmission measurement hypothesis. For a coherent transmission measurement hypothesis, it corresponds to a CMR measurement resource. If there are 4 CMR port groups in resource configuration, 4 CPU resources need to be occupied. For the non-coherent transmission measurement assumption, the measurement assumption corresponds to one CMR measurement resource and occupies 1 CPU resource. When the terminal has only one available CPU resource left at the current moment, the terminal only updates the CSI corresponding to the feedback non-coherent transmission measurement hypothesis.

In the foregoing possible implementation manner, after updating the partial CSI in the first CSI report, the terminal may feed back the updated partial CSI to the network side device.

In a possible implementation manner, when the terminal performs CSI update according to the number of CPUs occupied by the terminal and the number of unoccupied CPUs of the terminal, When the number of CPUs is less than the number of CPUs occupied and the first CSI report contains target coherent cooperative transmission CSI, if the first number of CPUs is less than the second number of CPUs and greater than or equal to 1, the terminal can use the calculation method of the target Part of the target resource acquisition part of the coherent coordinated transmission CSI is the target coherent coordinated transmission CSI, wherein the first number of CPUs is the number of CPUs that can be used to update the coherent coordinated transmission CSI among the unoccupied CPUs of the terminal, and the second 2. The number of CPUs is the number of CPUs required to obtain the complete target coherent cooperative transmission CSI, and the target resources include at least one of the following: channel measurement resources, channel measurement resource groups, channel measurement resource port groups, and channel measurement resource ports. Through this possible implementation manner, when the number of CPUs available to the terminal is insufficient, the terminal can use part of the resources to measure incomplete CSI reports, thereby maximizing the use of resources and avoiding waste of resources.

For example, the network side device configures a CSI report setting for the terminal, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set to obtain coherent cooperative transmission CSI, Then the terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting (including the CSI report of coherent cooperative transmission CSI) is 4, but at this time the number of CPUs available to the terminal is 3, and the terminal follows the default rule. Only use the channel The first 3 port groups of the measurement resource set obtain incomplete coherent transmission CSI.

In a possible implementation manner, after obtaining part of the target coherent coordinated transmission CSI by using part of the target resources used to calculate the target coherent coordinated transmission CSI, the terminal may feed back the obtained part of the target coherent coordinated transmission CSI, for example, the terminal reports A second CSI report, where the second CSI report includes the obtained partial target coherent coordinated transmission CSI.

In a possible implementation manner, the second CSI report may further include indication information, where the indication information is used to indicate at least one of the following: the CSI included in the second CSI report is partial target coherent coordinated transmission CSI, Acquire the target resource of the CSI included in the second CSI report. Through this possible implementation manner, the network side device can know the size of the second CSI report, so as to correctly demodulate the second CSI report.

For example, the network side device configures a CSI report setting for the terminal, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set to obtain coherent transmission CSI, then The terminal determines that the number of CPUs occupied by the CSI report (including the CSI report of coherent cooperative transmission CSI) is 4, but at this time the number of CPUs available to the terminal is 3, then the terminal only uses the first 3 in the channel measurement resource set according to the default rules The port group obtains incomplete coherent transmission CSI and feeds back the CSI report , the terminal can report and calculate that the CSI report occupies 3 CPUs, and the network-side device can obtain the coherent transmission CSI included in the CSI report as the CSI corresponding to three port groups (that is, three TRPs). Therefore, the network-side device The size of the corresponding CSI report can be known, so as to correctly demodulate the CSI report.

In another possible implementation manner, after calculating the target coherent coordinated transmission CSI using part of the target resource acquisition part of the target coherent coordinated transmission CSI, the terminal may send a notification to the network side device through the feedback target indication information, wherein the target indication includes one of the following: channel measurement resource indication, channel measurement resource group indication, channel measurement resource port group indication, channel measurement resource port indication; the notification information is used to indicate at least one of the following: The CSI included in the second CSI report fed back by the terminal is part of the target coherent coordinated transmission CSI, and the target resource for obtaining the CSI included in the second CSI report.

For example, the network side device configures a CSI report setting for the terminal, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set to obtain coherent transmission CSI, then the terminal It is determined that the number of CPUs occupied by the first CSI report configured by the CSI report setting (CSI report including coherent cooperative transmission CSI) is 4, but at this time the number of CPUs available to the terminal is 3, then the terminal uses port group 1/2/3 to obtain Incomplete coherent transmission CSI, when feeding back the CSI report, the terminal can report the port group indication for calculating the CSI report, which is associated with port group 1/2/3, and the network side device can obtain the coherent cooperation included in the CSI report The transmission CSI is the CSI corresponding to the three port groups (that is, the three TRPs), so the network side device can obtain the size of the corresponding CSI report, so as to correctly demodulate the CSI report.

In yet another possible implementation, after calculating the target coherent coordinated transmission CSI using part of the target resource acquisition part of the target coherent coordinated transmission CSI, the terminal sends notification information to the network side device through the fed back PMI, wherein, The notification information is used to indicate at least one of the following: the CSI included in the second CSI report fed back by the terminal is part of the target coherent coordinated transmission CSI, and the target resource for obtaining the CSI included in the second CSI report.

For example, the network side device configures a CSI report setting for the terminal, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set to obtain coherent transmission CSI, then The terminal determines that the number of CPUs occupied by the first CSI report configured by the CSI report setting (the CSI report including the coherent cooperative transmission CSI) is 4, but at this time the number of CPUs available to the terminal is 3, and the terminal uses the port Group 1/2/3 obtains incomplete coherent cooperative transmission PMI, which is composed of multiplication of multiple parts, one of which is composed of airspace information of 4 port groups (4 TRPs), if the terminal only reports three of them The airspace information of the port group, the airspace information of another port group is empty or 0 vector, then the network side device can determine the three port groups (that is, three TRPs) by first demodulating the CSI part including the airspace information, so as to obtain The remaining CSI part corresponds to three TRPs, therefore, the network side device can know the size of the corresponding remaining part, so as to correctly demodulate the CSI report.

For another example, the network side device is configured with a CSI report setting, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set to obtain coherent transmission CSI, then the terminal It is determined that the number of CPUs occupied by the CSI report (including the CSI report of coherent cooperative transmission CSI) is 4, but at this time the number of CPUs available to the terminal is 3, then the terminal uses port group 1/2/3 to obtain the incomplete coherent cooperative transmission PMI, The PMI is composed of multiple parts, one of which is composed of coefficients (magnitude coefficient and phase coefficient). The network can obtain the number of non-zero coefficients through the first demodulated CSI part, and obtain the coherence through the number of non-zero coefficients The transmission PMI is calculated for 3 port groups, so that the remaining CSI part corresponds to three TRPs. Therefore, the network can know the size of the corresponding remaining part, so as to correctly demodulate the CSI report.

In a possible implementation manner, when the terminal performs CSI update according to the number of CPUs occupied by the terminal and the number of unoccupied CPUs of the terminal, when the number of unoccupied CPUs of the terminal is smaller than the number of CPUs occupied by the terminal number and the first CSI report includes target coherent cooperative transmission CSI, if the first number of CPUs is less than the second number of CPUs and greater than or equal to 1, the terminal uses the first target CSI calculation delay to obtain the complete The target coherent coordinated transmission CSI, or use the second target CSI reference resource to obtain the complete target coherent coordinated transmission CSI; wherein, the first number of CPUs is the number of unoccupied CPUs of the terminal that can be used to update the coherent coordinated transmission The number of CPUs that transmit CSI, the second number of CPUs is the number of CPUs required to obtain the complete target coherent cooperative transmission CSI, and the first target CSI calculation delay is the orthogonal frequency corresponding to the first CSI report One of the first N1 CSI calculation delays with the largest number of division multiplexing (Orthogonal frequency division multiplex, OFDM) symbols, or the calculation delay corresponding to the first target CSI report through the first CSI report (ie The number of OFDM symbols) is obtained by calculating the first number of CPUs and the second number of CPUs, and the second target CSI reference resource is the first N2 CSIs with the smallest corresponding reference resource time slot in the first CSI report One of, N1 and N2 is greater than 0 an integer of .

For example, if the network side device is configured with a CSI report setting, the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set to obtain coherent transmission CSI, then the terminal determines The number of CPUs occupied by the CSI report (including the CSI report of coherent cooperative transmission CSI) is 4, but the number of CPUs available to the terminal at this time is 3, assuming that when the terminal uses 4 CPUs, the calculation delay of the CSI report is T, then at this time The calculation delay for the terminal to calculate the CSI report is 4/3*T.

For another example, the network side device is configured with a CSI report setting, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set to obtain coherent transmission CSI, and at the same time, The agreement agrees on the delay requirement table for the cooperative transmission CSI report. If the number of CPUs occupied by the terminal to obtain the CSI report (including the CSI report of coherent cooperative transmission CSI) is 4, but the number of CPUs available to the terminal at this time is 3, then this When the terminal calculates the calculation delay of the CSI report, the delay requirement with a large number of symbols in the table is adopted.

For another example, the network side device is configured with a CSI report setting, and the CSI report setting is associated with a channel measurement resource set, and a 16-port CMR with 4 port groups is configured in the channel measurement resource set to obtain coherent transmission CSI, and at the same time, The protocol agrees on multiple delay requirement tables for the cooperative transmission CSI report. If the terminal obtains the CSI report (including the CSI report of the coherent cooperative transmission CSI), the number of CPUs occupied is 4, but the number of CPUs available to the terminal at this time is 3. At this time, the calculation delay for the terminal to calculate the CSI report is obtained through the delay defined in the table with a larger delay.

In a possible implementation manner, before the terminal performs CSI update according to the number of CPUs occupied by the terminal and the number of unoccupied CPUs of the terminal, the method further includes: the terminal configures and/or Or the capability of the terminal is determined, when the number of unoccupied CPUs of the terminal is less than the number of CPUs occupied and the first CSI report includes target coherent cooperative transmission CSI, the first number of CPUs is less than the first When the number of two CPUs is greater than or equal to 1, the coherent cooperative transmission CSI is updated. That is to say, in this possible implementation, if the number of CPUs available to the terminal is insufficient, whether the terminal performs CSI update and acquisition can be determined by high-level parameter configuration. For example, if the high-level parameter configuration terminal cannot update incomplete Coordinated transmission CSI, or do not configure the parameters for updating incomplete cooperative transmission CSI, then when the number of CPUs that the terminal can use to update the cooperative transmission CSI is greater than or equal to 1 and less than the number of CPUs required to obtain complete coherent cooperative transmission CSI, the terminal does not update the cooperative transmission CSI. In addition, the terminal can also determine according to its capabilities. If the terminal has the ability to calculate the CSI of incomplete coherent cooperative transmission, it can calculate the CSI of incomplete coherent cooperative transmission based on the configuration of high-level parameters. Otherwise, the terminal does not perform CSI of incomplete coherent cooperative transmission. calculation.

In a possible implementation manner, when the terminal performs CSI update according to the number of CPUs occupied by the terminal and the number of unoccupied CPUs of the terminal, the number of unoccupied CPUs of the terminal is smaller than the number of CPUs In the case of the occupied quantity, the terminal does not update the CSI. That is to say, if the available CPU of the terminal is insufficient, the terminal does not update and feed back the CSI.

For example, the network-side device configures a CSI report setting for the terminal. The CSI report setting is associated with or configured with one coherent transmission measurement hypothesis and one non-coherent transmission measurement hypothesis. For a coherent transmission measurement hypothesis, it corresponds to a CMR measurement resource. If there are 4 CMR port groups in resource configuration, 4 CPU resources need to be occupied. For the non-coherent transmission measurement assumption, the measurement assumption corresponds to one CMR measurement resource and occupies 1 CPU resource. When the terminal has only one available CPU resource left at the current moment, the terminal does not update the CSI, that is, does not update the CSI report.
