Patent Description:
In high-frequency or low-frequency communication scenarios, accurate channel measurement techniques are required for improving communication transmission throughput and lowering communication delay. In a <NUM> generation-new radio system (<NUM>-NR), a flexible channel state information (CSI) measurement and reporting mechanism meets requirements on accurate CSI in different scenarios, especially high-frequency communication scenarios. Generally speaking, a network device usually configures CSI measurement resources to allow a terminal equipment to measure CSI in corresponding resources. Furthermore, the network device needs to make the terminal equipment know calculation results of which CSI need to be fed back.

In existing techniques, a <NUM>-NR system may indicate a measurement purpose of CSI. That is, by indicating the number of CSI measurement resources corresponding to the CSI report resource, the terminal equipment may learn the measurement purpose of the CSI measurement resource, so as to perform corresponding feedback of calculation. <FIG> shows three pieces of different measurement feedback. As shown in <FIG>, when a CSI report setting configuration (CSI-Report) is associated with a resource setting, for example, when the CSI-Report is associated with a channel measurement resource (CMR), the resource setting (such as a CMR) is used for layer <NUM> reference signal received power (L1-RSRP) channel measurement; when a CSI report setting configuration is associated with more than one resource settings, for example, the CSI-Report is associated with the CMR and a non-zero power CSI reference signal-based (NZP-CSI-RS based) interference measurement resource (IMR) (NZP-IMR for short), or the CSI-Report is associated with the CMR and a zero power CSI reference signal-based (ZP-CSI-RS based) interference measurement resource (IMR) (ZP-IMR for short), or the CSI-Report is associated with the CMR, the NZP-IMR and the ZP-IMR, a first resource setting (such as a CMR) is used for channel measurement instead of L1-RSRP measurement, and the other resource settings (such as the NZP-IMR and/or the ZP-IMR) are used for interference measurement.

Prior art document "<NPL>) is a 3GPP change request relating to modification of CPU occupancy rules when reportQuantity is set to 'none'.

Prior art document "<NPL>) is a 3GPP discussion and decision document relating to proposals on the details of CSI calculation time for aperiodic CSI reporting, several open issues for the location of CSI reference resource for periodic and semi-persistent CSI reporting, details of CSI processing unit definition and other remaining issues on NR CSI reporting.

Prior art document "<NPL>) is a 3GPP discussion and decision document relating to remaining issues on CSI reporting including definition of CSI processing unit, rule for multiple CSI reports, and CSI report linked with multiple CSI-RS resources.

It was found by the inventors that in performing communications in high frequency band, if L1-RSRP-based channel measurement feedback is only relied on, a communication system is unable to successfully perform beam management in a strong interference environment. In order to better deal with interference by the beam management in high frequency band, a L1-SINR-based channel measurement feedback mechanism is indispensable, which may effectively make up for the deficiencies of existing mechanisms.

However, when L1-SINR is added as a new CSI reporting indicator into a framework of CSI measurement reporting, existing mechanisms of a <NUM>-NR system are unable to determine a purpose of measurement of a CSI resource in some cases. As shown in <FIG>, when a CSI report setting configuration is associated with more than one resource settings, a terminal equipment is unable to determine purposes of these resource settings. A reason is that it is possible that channel measurement resources (CMRs) and interference measurement resources (IMRs) may be both configured at the same time for L1-SINR-based beam management measurement and general channel measurement (non-L1-SINR). If the terminal equipment is unable to distinguish a measurement purpose to which the CSI measurement resources correspond, it is possible that the following two situations may occur where:.

In addition, for measurement reference signals of different purposes, the CSI calculation resources occupied thereby are also different. For example, when L1-SINR-based beam management is adopted, the calculation resources occupied by its corresponding measurement resources are unclear, which may make it impossible for the terminal equipment and network device to make an agreement on the number of occupied CSI calculation resources within a period of time, and as a result, the number of CSI measurements or calculations configured by the network device for the terminal equipment goes beyond the computing capacity of the terminal equipment, which affects the system performance.

In order to solve at least one of the above problems or other similar problems, embodiments of this disclosure provide a method and apparatus for indicating a resource occupied for channel state information and a system.

Implementations of the embodiments of this disclosure shall be described below with reference to the accompanying drawings. These implementations are illustrative only, and are not intended to limit this disclosure. Examples <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM> and <NUM> are not encompassed by the wording of the claims but are considered as useful for understanding the invention.

The example of this disclosure provides a method for indicating a measurement purpose of CSI, applicable to a terminal equipment. <FIG> is a schematic diagram of the method for indicating a measurement purpose of CSI of this example. Referring to <FIG>, the method includes:.

In this example, the network device directly indicates a measurement purpose of a CSI measurement resource set via the above first indication information. Therefore, the terminal equipment may directly determine the measurement purpose of the CSI measurement resource set after receiving the first indication information. Thus, CSI measurement errors due to misunderstanding of the purpose of the CSI measurement resource set by the network device and the terminal equipment may be avoided.

In this example, the above measurement purpose may be channel measurement, or interference measurement, or channel measurement and interference measurement. The channel measurement may be channel measurement used for beam management, or channel measurement used for CSI acquisition, or channel measurement used for time-frequency pursuit, or any combination thereof.

In this example, the channel measurement used for beam management may include at least one of the following:.

In this example, the channel measurement used for CSI acquisition may include at least one of the following:.

What described above are examples only. Types of the channel measurement and interference measurement are not limited in this example, and reference may be made to existing standards or future-developed channel measurement or interference measurement techniques.

In this example, at least one CSI measurement resource in the first CSI measurement resource set may be used to perform at least one of the following measurements:.

Therefore, the terminal equipment may acknowledge which one or more of the above types are measurement purposes of the CSI measurement resources in the first CSI measurement resource set according to the first indication information.

In this example, the above first CSI measurement resource set may be any one of the following:.

Therefore, the terminal equipment may acknowledge measurement purposes of the reference signal resources in any one of the above sets according to the first indication information.

In this example, the above one or more CSI measurement resource sets may be associated with a CSI report set.

In this example, the above first CSI measurement resource set may include at least one of the following reference signal resources:.

Therefore, the terminal equipment may acknowledge the measurement purposes of the reference signal resources included in the first CSI measurement resource set according to the first indication information.

In this example, the measurement purpose of the first CSI measurement resource set may be identical to a measurement purpose of another CSI measurement resource set (referred to as a second CSI measurement resource set), and the first CSI measurement resource set is related to the second CSI measurement resource set.

In one implementation, the second CSI measurement resource set may be a set of all CSI measurement resources.

In this implementation, the first CSI measurement resource set may be a subset of the second CSI measurement resource set, that is, the network device indicates a measurement purpose of a part of the CSI measurement resources via the first indication information.

In this implementation, the first CSI measurement resource set and the second CSI measurement resource set may be identical, that is, the network device indicates measurement purpose of all CSI measurement resources via the first indication information. In addition, the first CSI measurement resource set may correspond to all resources with which a CSI report is associated.

In this implementation, the CSI report set with which the second CSI measurement resource set is associated and the CSI report set with which the first CSI measurement resource set is associated may be identical. Hence, the first indication information may indicate more flexibly. For example, a CSI measurement resource set to which a CSI report set A corresponds is {A0, A1, A2, A3}. The first CSI measurement resource set is A1, and the second CSI measurement resource set is {A0, A1, A2, A3}. thus, it may be extended to indicating all or a part of resources included in the entire CSI report set A by indicating a purpose of one resource.

With the method of this example, the network device directly indicates the measurement purpose of the CSI measurement resource set, thereby avoiding CSI measurement errors due to misunderstanding of the measurement purpose of the CSI measurement resource set by the network device and the terminal equipment.

The example provides a method for indicating a measurement purpose of CSI, applicable to a network device. This method is processing at a network device side corresponding to the method of Example <NUM>, with contents identical to those in Example <NUM> being not going to be described herein any further.

<FIG> is a schematic diagram of the method for indicating a measurement purpose of CSI of this example. As shown in <FIG>, the method includes:.

In this example, a manner of generating the first indication information is not limited.

The example of this disclosure provides a method for indicating a measurement purpose of CSI, applicable to a terminal equipment. Different from the methods in Examples <NUM> and <NUM> where indication is performed directly, the measurement purpose of the first CSI measurement resource set is indirectly indicated in this example. <FIG> is a schematic diagram of the method for indicating a measurement purpose of CSI of this example. Referring to <FIG>, the method includes:.

In this example, the network device indicates via the second indication information that a CSI measurement resource set (referred to as a second CSI measurement resource set) is related to one or some aspects. Hence, after receiving the second indication information, the terminal equipment may indirectly determine the measurement purpose of the CSI measurement resource set, thereby avoiding CSI measurement errors due to misunderstanding of the measurement purpose of the CSI measurement resource set by the network device and the terminal equipment.

Generally speaking, a CSI measurement resource set used for beam management uses an indication "repetition = on". Therefore, an IE "repetition" has a strong correlation with a measurement purpose of CSI-RS (especially beam management). In this example, whether the IE is configured may be taken as a basis for determining whether the CSI measurement resource set is for beam management (such as L1-SINR or L1-RSRP or L1-RSRQ, etc.). In addition, an SSB itself occupies less time-frequency resources and is not suitable for being taken as a measurement purpose of CSI acquisition or time-frequency pursuit. Therefore, when measurement resources include SSB resources, the purpose of the measurement resource set may be used for beam management (L1 -SINR or L1-RSRP or L1-RSRQ etc.). In addition, for a CSI measurement resource set, its corresponding reported contents may indirectly indicate the purpose of the CSI measurement resource in many cases. For example, if a reported content corresponding to a CSI measurement resource is related to L1-SINR, L1 -RSRP and L1-RSRQ, the set may be used for beam management, and if the set is related to PMI, LI, CQI, and RI, etc., the set may be used for CSI acquisition.

In one implementation of this example, in the CSI measurement resource set for channel measurement associated with the CSI report set corresponding to the second CSI measurement resource set, if the above "repetition" is configured, the measurement purpose of the second CSI measurement resource set is channel measurement for beam management.

In this implementation, the above "repetition" refers to an IE in RRC signaling, which is used to configure an NZP CSI-RS measurement set. When the set is configured with the above "repetition", it may have two possible states: repetition=on and repetition=off.

In a case where repetition=on, all NZPCSI-RS resources in the above NZP CSI-RS measurement set are transmitted by the same spatial filter, and each of the above NZPCSI-RS resources is transmitted on different OFDM symbols.

In a case where repetition=off, the terminal equipment shall not assume that all CSI-RS resources in the NZP CSI-RS measurement set are transmitted by the same spatial filter.

Therefore, the terminal equipment may determine the measurement purpose of the second CSI measurement resource set according to the above relationship (for the second CSI measurement resource set, whether "repetition" is configured) indicated by the second indication information.

In another implementation of this example, in the CSI measurement resource set for channel measurement associated with the CSI report set corresponding to the second CSI measurement resource set, if the above "SSB" is included, the measurement purpose of the above second CSI measurement resource set is for channel measurement for beam management. The above CSI measurement resource set used for channel measurement including "SSB" refers to that the CSI measurement resource set only includes "SSB" resources or the CSI measurement resource set includes not only "SSB" resources but also "CSI-RS" resources. The SSB is a synchronization signal/physical broadcast channel (SS/PBCH) block.

Therefore, the terminal equipment may determine the measurement purpose of the second CSI measurement resource set according to the relationship indicated by the second indication information (the second CSI measurement resource set includes the "SSB"). In addition, the second CSI measurement resource may include only CSI measurement resources, or may include CSI measurement resources and interference measurement resources related to the CSI measurement resources.

In a further implementation of this example, if the CSI measurement resource used for channel measurement in the second CSI measurement resource set includes at least one CSI-RS set and the CSI-RS set is configured with "repetition", the measurement purpose of the second CSI measurement resource set is channel measurement for beam management, and the second CSI measurement resource set includes at least one of the following: a CSI measurement resource used for channel measurement, and an interference measurement resource related to the CSI measurement resource used for channel measurement.

Thus, the terminal equipment may determine the measurement purpose of the second CSI measurement resource set according to the relationship indicated by the above second indication information (the second CSI measurement resource set includes a CSI-RS, and the CSI-RS is configured with "repetition"). And the second CSI measurement resource set may include only CSI measurement resources used for channel measurement, or include not only the CSI measurement resources used for channel measurement, but also interference measurement resources related to the CSI measurement resources used for channel measurement.

In another implementation of this example, if the report information corresponding to the CSI measurement resources used for channel measurement in the second CSI measurement resource set is related to at least one of L1-RSRP, L1-RSRQ, and an L1-SINR , the measurement purpose of the second CSI measurement resource set is channel measurement for beam management, and the second CSI measurement resource set includes at least one of the following: CSI measurement resources used for channel measurement, and interference measurement resources related to the CSI measurement resources used for channel measurement.

Therefore, the terminal equipment may determine the measurement purpose of the second CSI measurement resource set according to the relationship indicated by the second indication information (the report information is related to at least one of L1-RSRP, L1-RSRQ and an L1-SINR). And the second CSI measurement resource set may include only CSI measurement resources used for channel measurement, or may include not only the CSI measurement resources used for channel measurement, but also interference measurement resources related to the CSI measurement resources used for channel measurement.

In the above implementation of this example, the channel measurement used for beam management may be at least one of the following: channel measurement used for L1-RSRP calculation, channel measurement used for L1-RSRQ calculation, and channel measurement used for L1-SINR calculation. Implementations of channel measurement used for beam management are not limited in this example.

In a further implementation of this example, if the CSI measurement resources used for channel measurement in the second CSI measurement resource set include at least one CSI-RS set and the CSI-RS set is not configured with "repetition", the measurement purpose of the second CSI measurement resource set is CSI acquisition or time-frequency pursuit, and the second CSI measurement resource set includes at least one of the following: CSI measurement resources used for channel measurement, and interference measurement resources related to the CSI measurement resources used for channel measurement.

Therefore, the terminal equipment may determine the measurement purpose of the second CSI measurement resource set according to the relationship indicated by the second indication information (the second CSI measurement resource set includes an CSI-RS, and the CSI-RS is not configured with "repetition"). And the second CSI measurement resource set may include only CSI measurement resources used for channel measurement, or may include not only the CSI measurement resources used for channel measurement, but also interference measurement resources related to the CSI measurement resources used for channel measurement.

In still another implementation of this example, if the report information corresponding to the CSI measurement resources used for channel measurement in the second CSI measurement resource set is related to at least one of a CQI, a PMI, an RI and L1, the measurement purpose of the second CSI measurement resource set is CSI acquisition or time-frequency pursuit, and the second CSI measurement resource set includes at least one of the following: CSI measurement resources used for channel measurement, and interference measurement resources related to the CSI measurement resources used for channel measurement.

Therefore, the terminal equipment may determine the measurement purpose of the second CSI measurement resource set according to the relationship indicated by the second indication information (the report information is related to at least one of a CQI, a PMI, an RI and L1). And the second CSI measurement resource set may include only CSI measurement resources used for channel measurement, or may include not only the CSI measurement resources used for channel measurement, but also interference measurement resources related to the CSI measurement resources used for channel measurement.

In yet another implementation of this example, the measurement purpose of the second CSI measurement resource set is for L1-RSRP or L1-RSRQ measurement if at least one of the following conditions is satisfied:.

Therefore, when the terminal equipment acknowledges according to the above second indication information that at least one of the above conditions is satisfied, it may determine that the measurement purpose of the second CSI measurement resource set is L1-RSRP or L1-RSRQ measurement.

In this implementation, in the above second condition, the CSI measurement resource set used for channel measurement is not used for time-frequency pursuit, that is, the CSI measurement resource set used for channel measurement is not configured with trs-info, the trs-info IE being used to indicate that all CSI-RS resources in the set have identical antenna ports.

In this implementation, in the above third condition, being only associated with the CSI measurement resources used for channel measurement refers that, being not associated with the interference measurement resources.

In yet still another implementation of this example, the measurement purpose of the second CSI measurement resource set is L1-SINR measurement if at least one of the following conditions is satisfied:.

Therefore, when the terminal equipment acknowledges according to the above second indication information that at least one of the above conditions is satisfied, it may determine that the measurement purpose of the second CSI measurement resource set is L <NUM>-SINR measurement.

In this implementation, a meaning of the fifth condition is identical to that of the second condition, and shall not be described herein any further.

In this example, if the CSI measurement resources used for channel measurement in the second CSI measurement resource set include one of a CSI-RS and an SSB, a relationship between the CSI-RS or SSB and a corresponding interference measurement resource is of a quasi-colocation (QCL) type C and/or a quasi-colocation type D.

That is, the CSI measurement resources used for channel measurement in the second CSI measurement resource set include only CSI-RSs or include only SSBs, and a relationship between the CSI measurement resources (CSI-RSs or SSBs) and corresponding interference measurement resources is of the QCL Type-C and/or the QCL Type-D. <FIG> is a schematic diagram of the relationship between the CSI-RSs or SSBs and the corresponding interference measurement resources.

In this example, if the CSI measurement resources used for channel measurement in the second CSI measurement resource set include CSI-RSs and SSBs, a relationship between the CSI-RSs and SSBs and corresponding interference measurement resources is of the QCL Type-C and/or the QCL Type-D.

That is, the CSI measurement resources used for channel measurement in the second CSI measurement resource set include not only CSI-RSs but also SSBs, the relationship between the CSI measurement resources (CSI-RSs and SSBs) and the corresponding interference measurement resources is of the QCL Type-C and/or QCL Type-D. <FIG> is a schematic diagram of the relationship between the CSI-RSs and SSBs and the corresponding interference measurement resources.

In this example, if the CSI measurement resources used for channel measurement in the second CSI measurement resource set include CSI-RSs and SSBs, the numbers of the CSI-RSs and SSBs may be identical, and they may one by one to correspond each other according to their orders in respective resource sets, as shown in <FIG>.

In this example, the CSI measurement resource used for channel measurement in the second CSI measurement resource set and a QCL assumption of the corresponding interference measurement resources may be identical. Thus, when the resources used for channel measurement and the resources used for interference measurement use identical QCL assumptions, their spatial filters for reception are identical. Hence, consistency of the channel measurement and the interference measurement may be ensured, and inaccurate measurement results may be avoided.

In this example, the number of subsets of CSI measurement resources used for channel measurement in the second CSI measurement resource set and the number of subsets of corresponding interference measurement resources may be identical and sequentially correspond, as shown in <FIG> or <FIG>. The subsets may have only one reference signal (an SSB or a CSI-RS), or they may have multiple reference signals. In addition, serial numbers (#<NUM>, and #<NUM>, etc.) in <FIG> and <FIG> may refer to one or more than one reference signal resources.

In this example, if the second CSI measurement resource set is related to at least one of L1-RSRP, L1-RSRQ and an L1-SINR, contents reported by the terminal equipment may consist of a part (CSI feedback consist of a single part). Therefore, as the reported contents of L1-RSRP, L1-RSRQ and L1-SINR need less bits, there is no need to divide them into multiple parts for performing CSI feedback. Therefore, all CSI feedback needs to be reported at a time to avoid additional overhead.

With the method of this example, the network device indirectly indicates the measurement purpose the CSI measurement resource set, thereby avoiding CSI measurement errors due to misunderstanding of the measurement purpose of the CSI measurement resource set by the network device and the terminal equipment.

In this example, a manner of generating the second indication information is not limited.

With the method of this example, the network device indirectly indicates the measurement purpose of the CSI measurement resource set, thereby avoiding CSI measurement errors due to misunderstanding of the measurement purpose of the CSI measurement resource set by the network device and the terminal equipment.

The embodiment of this disclosure provides a method for indicating a resource occupied for CSI calculation, applicable to a terminal equipment. Different from the methods in Examples <NUM> and <NUM> where the measurement purpose of CSI is directly indicated and the methods in Examples <NUM> and <NUM> where the measurement purpose of CSI is indirectly indicated, in this embodiment, according to specific rules, indication information from a base station is interpreted as corresponding resource occupied for CSI calculation. As the purpose of CSI measurement can be different, the resources occupied for CSI calculation can be different, hence, the resource occupied for CSI calculation is a representation of a measurement purpose of CSI (this embodiment is not limited thereto). This embodiment may also be understood as that a terminal equipment directly associates an indication of the base station with the resources occupied for CSI calculation, independent of the measurement purpose of CSI, which is hereby stated.

In Examples <NUM>-<NUM>, after receiving the above indication information (the first indication information or the second indication information), the terminal equipment may determine a measurement purpose of a corresponding CSI measurement resource set. For CSI report or CSI measurement to which CSI measurement resource sets of different measurement purposes correspond, the number and duration of CSI processing units (CPUs in brief) occupied thereby are different. In this embodiment, it may also be understood as that the terminal equipment directly determines the number and duration of CPUs corresponding to the indication information after receiving the above indication information (the first indication information or second indication information).

<FIG> is a schematic diagram of the method for indicating a resource occupied for CSI calculation of this embodiment. As shown in <FIG>, the method includes:.

In this embodiment, the conditions associated with a first CSI report set include:.

In this embodiment, the terminal equipment determines the time T and the number K of the CPUs occupied by the CSI report or the CSI measurement to which the first CSI report set corresponds according to the conditions associated with the first CSI report set indicated by the third indication information.

In this embodiment, the number K of the CPUs occupied by the CSI report or the CSI measurement to which the first CSI report set corresponds may be at least one of the following: <NUM>; <NUM>; <NUM>; Ks; and NCPU.

In this embodiment, Ks may be at least one of the following: the number of SSB resources, the number of CSI-RS resources, a maximum value of the number of CSI-RS resources and the number of SSB resources, and a sum of the number of CSI-RS resources and the number of SSB resources.

For example, if the CSI channel measurement resource set with which the first CSI report set is associated only includes the SSBs, Ks is the number of SSB resources; if the CSI channel measurement resource set with which the first CSI report set is associated only includes CSI-RSs, Ks is the number of CSI-RS resources; and if the CSI channel measurement resource set with which the first CSI report set is associated includes CSI-RSs and SSBs, Ks is a maximum value of the number of CSI-RS resources and the number of SSB resources, or Ks is the sum of the number of CSI-RS resources and the number of SSB resources.

In this embodiment, the above NCPU is the number of parallel CPUs supported by the terminal equipment. In this embodiment, the terminal equipment may report its parallel CSI calculation capability NCPU to the network side according to its own capabilities. NCPU refers to the number of CSI processing units (CPUs) used by terminal equipment in CSI report processing in all configured cells. If L CPUs on a given OFDM symbol are occupied to calculate the CSI report, it is deemed that the terminal equipment has NCPU-L unoccupied CPUs. Assuming that the number of pieces of CSI report is n=<NUM>,<NUM>,. ,N-<NUM>, in which the number of CPUs occupied by each pieces CSI report is
<MAT>
if
<MAT>
is satisfied, where <NUM>≤M≤N, the terminal equipment needs not to report measurement results of N-M pieces of CSI of lowest priorities.

In this embodiment, if the terminal equipment needs to perform CSI report, a time T of a CPU occupied by CSI report corresponding to the first CSI report set may be at least one of the following:
for example, if the CSI report is aperiodic CSI report, time T of the CPU occupied by the CSI report is: from a first or a last symbol after downlink control information (PDCCH) triggering the CSI report to a first or a last symbol of an uplink shared channel (PUSCH) or an uplink control channel (PUCCH) carrying the CSI report.

<FIG> shows an example of a time T of a CPU occupied by CSI report in a case of aperiodic CSI report. In this example, the time T is from a first symbol after a PDCCH triggering the CSI report to a last symbol of a PUCCH/PUSCH carrying the CSI report.

For another example, if the CSI report is periodic CSI report, time T of the CPU occupied by the CSI report is: from a first or a last symbol of a CSI measurement occasion related to the CSI report to a first or a last symbol of an uplink shared channel (PUSCH) or an uplink control channel (PUCCH) carrying the CSI report.

The above CSI measurement occasion refers to that there are total Q CSI measurement resources related to the CSI report, measurement occasions where each resource corresponds to a latest measurement occasion for the CSI report and not later than the corresponding CSI reference resource are expressed as a set M = {O<NUM>, O<NUM>,. ,OQ}, an earliest measurement occasion M' is taken from the set M, and M' is the above CSI measurement occasion.

CSI measurement resources to which the above CSI measurement occasion corresponds may be channel measurement resources or interference measurement resources (if there exist interference measurement resources). In particular, they may be CSI-RS resources, or CSI-IM resources, or SSB resources.

<FIG> shows an example of a time T of a CPU occupied by CSI report in a case of periodic CSI report. In this example, the time T is from a first symbol of a CSI measurement occasion to a last symbol of a PUCCH or PUSCH carrying the CSI report.

For a further example, if the above CSI report is semi-persistent CSI report carried by an uplink shared channel (PUSCH) and is initially triggered by downlink control information (PDCCH), the time T of the CPU occupied by the CSI report is: from a first or a last symbol after the downlink control information (PDCCH) triggering the CSI report to a first or a last symbol of the uplink shared channel (PUSCH) carrying the CSI report.

<FIG> shows an example of a time T of a CPU occupied by CSI report in a case of semi-persistent CSI report triggered by a PDCCH. In this example, as shown in <FIG>, for CSI report initially triggered by the PDCCH, the time T is from a first symbol after the PDCCH triggering the CSI report to a last symbol of a PUSCH carrying the CSI report.

For still another example, if the above CSI report is semi-persistent CSI report carried by an uplink shared channel (PUSCH) but is not initially triggered by downlink control information (PDCCH), the time T of the CPU occupied by the CSI report is: from a first or a last symbol of a CSI measurement occasion related to the CSI report to a first or a last symbol of an uplink shared channel (PUSCH) carrying the CSI report. Meanings of the CSI measurement occasion and CSI measurement resources to which the CSI measurement occasion corresponds are identical to those described above, and shall not be described herein any further.

As shown in <FIG>, a time T of a CPU occupied by other CSI report than the CSI report initially triggered by the PDCCH is from a first symbol of a corresponding CSI measurement occasion (corresponding to the CSI measurement occasion in the above examples) to the last symbol of the PUSCH carrying the CSI report. <FIG> shows an example of a time T of a CPU occupied by CSI report in a case of semi-persistent CSI report triggered by an MAC-CE. In this example, a time T of a CPU occupied by the CSI reports is from a first symbol of a corresponding CSI measurement occasion (corresponding to the CSI measurement occasion in the above examples) to the last symbol of the PUSCH carrying the CSI report.

In this embodiment, if the terminal equipment needs not to perform CSI report, the time (T) of CPUs occupied by CSI measurement to which the first CSI report set corresponds (i.e. CPUs occupied by calculating the CSI measurement) may be at least one of the following.

For example, if a time domain behavior to which the CSI report set corresponds is aperiodic, the time (T) of CPUs occupied by the CSI measurement to which the CSI report set corresponds is: from a first or a last symbol after the downlink control information (PDCCH) triggering the CSI report set to a maximum value of x+Z<NUM> and y+Z<NUM>.

The above x is the first or last symbol after the downlink control information (PDCCH) triggering the CSI report set, the above Z<NUM> is a CSI calculation time related to the CSI measurement or report triggered by the control information, the above y is a last symbol of a latest CSI channel measurement resource or interference measurement resource related to the CSI report set, and the above Z<NUM> is a CSI calculation time related to the CSI measurement resource.

The above Z<NUM> is related to a subcarrier spacing, and/or is related to a calculation purpose and/or a reported content (L1-RSRP, L1-SINR, L1-RSRQ) corresponding to the above CSI report set; for example, when the calculation purpose is L1-RSRP, for a value of Zo, when a subcarrier spacing is <NUM>, Zo=<NUM> symbols; when a subcarrier spacing is <NUM>, Zo=<NUM> symbols; when a subcarrier spacing is <NUM>, Zo=min(<NUM>, Z<NUM>+KB1) symbols; and when a subcarrier spacing is <NUM>, Zo=min(<NUM>, Z<NUM>+KB2) symbols; wherein KB1 and KB2 are related to an ability of the terminal equipment to report to the network side. The ability refers to a time needed by the terminal equipment in receiving a PDCCH and applying space (QCL) information indicated by the PDCCH to receive a corresponding PDSCH. For example, at <NUM>, KB1 = {<NUM>,<NUM>,<NUM>}; and at <NUM>, KB2 = {<NUM>,<NUM>}. When the calculation purpose is for L1-SINR, a value of Z<NUM> is greater than a value of Z<NUM> (when the calculation purpose is for L1-RSRP or L1-RSRQ). This is because that a calculation complexity of L1-SINR is higher than that of L1-RSRP or L1-RSRQ, and a longer CSI calculation time is needed.

The above Z<NUM> is related to an ability of the terminal equipment to report to the network side. The ability refers to that the terminal equipment reports different report processing times related to the CSI calculation for beam management to the network side according to different subcarrier spacings. The processing times related to the CSI calculation for beam management may refer to being related a calculation purpose (L1-RSRP, L1-SINR, L1-RSRQ) corresponding to the above CSI report set.

The above channel measurement resources or interference measurement resources may be used for L1-SINR measurement, for example, they may be one of a CSI-RS, an SSB, and a CSI-IM. furthermore, periods of the above channel measurement resources and interference measurement resources (if there exist interference measurement resources) used for the L1-SINR measurement may be identical. An advantage that the periods of these resources are identical is that fairness and accuracy of results of joint estimation by channel measurement and interference measurement may be ensured.

<FIG> shows two examples of a time T of a CPU occupied by corresponding CSI measurement in a case where a CSI report set is aperiodic. As shown on the left side of <FIG>, x+Z<NUM><y+Z<NUM>, and the time T of the CPU occupied by the corresponding CSI measurement is a first symbol after a PDCCH triggering the CSI report to y+Z<NUM>; as shown on the right side of <FIG>, x+Z<NUM>>y+Z<NUM>, and the time T of the CPU occupied by the corresponding CSI measurement is a first symbol after a PDCCH triggering the CSI report to x+Z<NUM>.

For another example, if the time domain behavior corresponding to the above CSI report set is periodic, the time (T) of the CPU occupied by the CSI measurement corresponding to the CSI report set is: from a first symbol of an earliest measurement occasion in measurement occasions of the CSI measurement resources associated with the CSI report set in a transmission occasion associated with the CSI report set to y'+Z<NUM>. A meaning of Z<NUM> is identical to what is described above, and y' is a last symbol of a latest measurement occasion in transmission occasions of the CSI measurement resources related to the CSI report set in the above transmission occasions. The above CSI measurement resources may be resources used for CSI channel measurement, and may also be resources used for interference measurement.

<FIG> shows an example of a time T of a CPU occupied by CSI measurement in a case where a CSI report set is periodic. As shown in <FIG>, in transmission occasion #<NUM> or transmission occasion #N, the CPU occupancy time is from resource #<NUM> to resource #<NUM>+Z<NUM>, resource #<NUM> is (the first symbol of) the above earliest measurement occasion, and resource #<NUM> is (the first or last symbol of) the above latest measurement occasion.

For another example, if the time domain behavior corresponding to the above CSI report set is semi-persistent, and initial CSI measurement corresponding to the CSI report set is triggered by downlink control information (PDCCH), for the CSI measurement, the time (T) of the CPU it occupies is from a first symbol after the downlink control information (PDCCH) triggering the CSI report set to a maximum value of x+Z<NUM> and y+Z<NUM>. Meanings of x, Z<NUM>, y and Z<NUM> are identical to what is described above.

<FIG> and <FIG> show two examples of a time T occupied by CSI measurement corresponding to the CSI report set in a case of a semi-persistent CSI report set triggered by a PDCCH. In the example of <FIG>, x+Z<NUM><y+Z<NUM>, for CSI measurement initially triggered by the PDCCH, the time T of the CPU occupied by the CSI measurement is a first symbol after the PDCCH triggering the CSI measurement to y+Z<NUM>; and in the example in <FIG>, x+Z<NUM>>y+Z<NUM>, the time T of the CPU occupied by the CSI measurement is a first symbol after the PDCCH triggering the CSI report to x+Z<NUM>.

For another example, if the time domain behavior corresponding to the above CSI report set is semi-persistent, a time (T) of a CPU occupied by CSI measurement to which the CSI report corresponds other than CSI measurement initially triggered by a PDCCH is: from a first symbol of an earliest measurement occasion in measurement occasions of the CSI measurement resources related to the CSI report set to y'+Z<NUM>. Meanings of y' and Z<NUM> are identical to what is described above. The above CSI measurement resources may be resources used for CSI channel measurement, and may also be resources used for interference measurement.

<FIG> shows an example of a time T of a CPU occupied by CSI measurement to which a CSI report set corresponds in a case of semi-persistent CSI report triggered by an MAC-CE. In this example, as shown in <FIG>, for each transmission occasion, the CPU occupancy time T is from resource #<NUM> to resource #<NUM>+Z<NUM>, resource #<NUM> is (the first symbol of) the above earliest measurement occasion, and resource #<NUM> is (the first symbol of) the above latest measurement occasion. As shown in <FIG> and <FIG>, the CPU occupancy time T for each of other transmission occasions than the transmission occasion (a first transmission occasion) to which related CSI measurement initially triggered by a PDCCH corresponds is from resource #<NUM> to resource #<NUM>+Z<NUM>, resource #<NUM> is (the first symbol of) the earliest transmission occasion in the other transmission occasions, and resource #<NUM> is (the last symbol of) the latest measurement occasion in the other transmission occasions.

In an example, the terminal equipment receives signaling (such as RRC signaling) from a network device. The signaling indicates that the above CSI report set needs to perform CSI report and a content of the CSI report is related to L1-SINR measurement, then the CSI report to which the CSI report set corresponds occupies K CPUs, and a corresponding occupancy time is the occupancy time T in the case where the terminal equipment needs to perform CSI report described
above, examples of which being as shown in <FIG>.

In another example, the terminal equipment receives signaling (such as RRC signaling) from the network device. The signaling indicates that the above CSI report set need not to perform CSI report, and a channel measurement set to which the CSI report set corresponds is not used for time-frequency pursuit ("trs-info" is not configured), and the CSI measurement resource set with which the CSI report set is associated includes only a channel measurement resource set (not including an interference measurement resource set), then the CSI measurement to which the CSI report set corresponds occupies K CPUs, and a corresponding occupancy time is the occupancy time T in the case where the terminal equipment does not need to perform CSI report described above, examples of which being as shown in <FIG>.

The signaling indicates that the above CSI report set need not to perform CSI report, and a channel measurement set to which the CSI report set corresponds is not used for time-frequency pursuit ("trs-info" is not configured), and the CSI measurement resource set with which the CSI report set is associated includes not only a channel measurement resource set but also an interference measurement resource set, then the CSI measurement to which the CSI report set corresponds occupies K CPUs, and a corresponding occupancy time is the occupancy time T in the case where the terminal equipment does not need to perform CSI report described above, examples of which being as shown in <FIG>.

In still another example, the terminal equipment receives signaling (such as RRC signaling) from the network device. The signaling indicates that the above CSI report set needs to perform CSI report and a channel measurement set to which the CSI report set corresponds is configured with "repetition", then the CSI report to which the CSI report set corresponds occupies K CPUs, and a corresponding occupancy time is the occupancy time T in the case where the terminal equipment needs to perform CSI report described above, examples of which being as shown in <FIG>.
