Detailed Description
The present application will be described with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
In New Radio (NR) Release15, time and frequency resources controlled by a base station (e.g., gNB or TRP) may be used for the UE to report CSI. The CSI may be composed of a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Channel State Information-reference Signal Resource Indicator (CRI), an SS/PBCH Block Resource Indicator (SSBRI), a Layer Indicator (LI), a Rank Indicator (RI), and the like.
Fig. 1 is a schematic diagram of a TRP and terminal communication according to an embodiment. The base station side can flexibly configure the number of CMR resource resources, the measurement mode and the like. As shown in fig. 1, a TRP may transmit one or more CMR resources to a UE through a beam. In addition, the TRP may also configure the UE with one or more CSI reporting feedback settings (CSI-ReportConfig) and one or more CSI resource settings (CSI-resourceconconfig), where one CSI reporting feedback setting may be linked to at most three CSI resource settings. And the UE measures and reports the CSI according to the CMRs.
The base station side may configure one or more Channel State Information-reference Signal (CSI-RS) resources for the UE to be used for useful Channel Measurement, and configure one or more Channel State Information Interference Measurement (CSI-IM) resources for Interference Measurement, where the CSI-RS resources and the CSI-IM resources are in a one-to-one correspondence relationship. Under the condition that one CSI-RS resource is used, the UE reports the CSI including RI, PMI, CQI and the like according to the measurement of the CSI-RS resource; in the case that there are multiple CSI-RS resources, usually multiple CSI-RS resources are precoded, each CSI-RS resource represents a precoding matrix, and precoding information for CSI-RS can be determined by the base station side, for example, by traversing Discrete Fourier Transform (DFT) beamforming vectors in the whole space, or by calculating from measurements on Sounding Reference Signals (SRS). The UE measures a plurality of CSI-RS resources, selects one CSI-RS resource with the best channel quality from the CSI-RS resources, reports CRI indicating the CSI-RS resource, and further feeds back CSI such as RI, PMI and CQI according to the measurement of the CSI-RS resource. If the base station side sets one CSI-RS resource for the UE for useful channel measurement and one or more CSI-RS resources for interference measurement, the measurement of the useful channel is associated with all interference measurement resources. In the CSI-RS interference measurement resources, each CSI-RS antenna port corresponds to one interference layer, a channel matrix measured by the UE on a plurality of antenna ports of each CSI-RS interference resource is an interference channel matrix, and the UE can further calculate a covariance matrix, a null space and the like of the interference channel through the matrix so as to calculate and feed back an optimal precoding matrix and CQI under the interference channel.
In the embodiment of the application, a method for reporting channel state information is provided, in which, in a process of measuring CSI, according to a pairing relationship between reference signal measurement resources corresponding to beams transmitted by different TRPs, interference between the reference signal measurement resources is considered, so that accuracy of CSI measurement and reporting is improved.
Fig. 2 is a flowchart of a method for reporting channel state information according to an embodiment, and as shown in fig. 2, the method according to this embodiment includes steps 110 and 120.
In step 110, a measurement resource configuration signaling is received, where the measurement resource configuration signaling is used to indicate M reference signal measurement resources and pairing information of the reference signal measurement resources, and M > 1.
In this embodiment, the pairing information is used to indicate a pairing relationship between the reference signal measurement resources, that is, indicate which reference signal measurement resources have interference therebetween. For example, the pairing information may be the number and number of resource pairs with interference in the M reference signal measurement resources, and/or the arrangement position in the buffer, and the UE may consider the interference caused by another reference signal measurement resource paired with the UE in the process of measuring the CSI of one reference signal measurement resource, thereby improving the accuracy of measurement. In addition, the pairing information may further include CSI reporting feedback settings or CSI resource settings corresponding to the M reference signal measurement resources, so as to instruct the UE to report CSI in different CSI reporting feedback settings for each reference signal measurement resource, or to combine CSI of resource pairs with interference and report the CSI in one CSI reporting feedback setting.
In step 120, the channel state information is reported according to the pairing information.
In this embodiment, when measuring the CSI of one reference signal measurement resource, the UE may consider interference caused by another reference signal measurement resource paired with the UE, so as to improve the measurement accuracy. The CSI can also be reported in different CSI reporting feedback settings for each reference signal measurement resource, or the CSI of the resource pair with interference can be combined and reported in one CSI reporting feedback setting.
In an embodiment, each reference signal measurement resource corresponds to at least one group identifier.
In this embodiment, the base station may configure at least one group identifier (GroupID) for each CMR Resource through Radio Resource Control (RRC) signaling, so as to indicate whether the CMR is used for pairing. A plurality of different group identities may be configured for CMR resources that may or may not be paired with other CMR resources.
In one example, each reference signal measurement resource corresponds to a respective packet identifier. For example, beams transmitted by the TRP1 are denoted as beam1, beam2, beam3, and beam4, and the corresponding CMR resources are denoted as CMR1, CMR2, CMR3, and CMR 4. Beams transmitted by the TRP2 are marked as beam5, beam6, beam7 and beam8, and corresponding CMR resources are marked as CMR5, CMR6, CMR7 and CMR 8. Wherein [ beam3, beam5], [ beam4, beam6] form two paired beam pairs, and beam1, beam2, beam7, beam8 do not perform beam pairing. In this case, the CMR resources in the CSI reporting feedback setting are { CMR3, CMR5, CMR4, CMR6, CMR1, CMR2, CMR7, and CMR8 }.
Table 1 is a mapping table of reference signal measurement resources and packet identifications. As shown in Table 1, CMR3 and CMR5 may correspond to the same group identity, with a GroupID of 0; CMR4 and CMR6 may correspond to the same group identity, with a GroupID of 1; there is no pairing relationship among the CMRs 1, 2, CMR7 and CMR8, and the corresponding group identifiers are 2, 3, 4 and 5 respectively. CMR3, CMR5, and CMR4, CMR6 are associated with the base station being a Multiple Transmission Reception Point (MTRP), while CMR1, CMR2, CMR7, CMR8 are associated with the base station being a Single Transmission Reception Point (STRP).
Table 1 mapping table of reference signal measurement resources and packet identities
Figure BDA0002877719360000041
In one example, each reference signal measurement resource may also correspond to multiple packet identifications. For example, if a CMR resource is associated with both STRP and MTRP, the base station configures two groupids for the CMR resource. For example, if beam3 of TRP1 may or may not be paired with beam5 of TRP2, CMR3 may correspond to two groupids.
Table 2 is another mapping table of reference signal measurement resources and packet identifications. As shown in table 2, CMR3 may correspond to two groupids, one GroupID being 0, indicating that CMR3 is paired with CMR5, [ CMR3, CMR5] associated with the base station being MTRP; another GroupID is 2, indicating that CMR3 is not paired with other CMR resources and CMR3 is associated with a STRP.
Table 2 mapping table of reference signal measurement resource and packet identifier
Figure BDA0002877719360000042
In an embodiment, reference signal measurement resources with the same group identity have a pairing relationship.
In this embodiment, the base station configures the same group identifier for the paired CMR resources, and configures an individual group identifier for the reference signal measurement resource that does not have a pairing relationship, so that the UE can accurately obtain pairing information of the CMR resources, and specify the CMR resources in which interference exists.
In this embodiment, in the process of configuring the group identifier for the CMR resource associated with the STRP and the CMR resource associated with the MTRP, the CMR resource associated with the STRP may be first allocated to the CMR resource associated with the MTRP and then allocated to the CMR resource associated with the STRP, regardless of the sequence, that is, the group identifier is increased from small to large.
In an embodiment, the measurement resource configuration signaling includes the number of resource pairs having a pairing relationship, N ≦ M/2.
In this embodiment, the base station configures a parameter N for indicating the number of resource pairs having a pairing relationship through RRC, and if there is no CMR resource that needs to be paired, N is 0.
For example, beams transmitted by the TRP1 are denoted as beam1, beam2, beam3, and beam4, and the corresponding CMR resources are denoted as CMR1, CMR2, CMR3, and CMR 4. Beams transmitted by the TRP2 are marked as beam5, beam6, beam7 and beam8, and corresponding CMR resources are marked as CMR5, CMR6, CMR7 and CMR 8. Wherein [ beam3, beam5], [ beam4, beam6] form two paired beam pairs, and beam1, beam2, beam7, beam8 do not perform beam pairing. In this case, the CMR resource in the CSI reporting feedback setting is { CMR3, CMR5, CMR4, CMR6, CMR1, CMR2, CMR7, CMR8}, where N is 2. The UE may sequentially take 4 CMR resources from front to back in the CMR resources requiring CSI reporting according to N-2, and pair every two CMR resources in sequence.
In some embodiments, in the case of N ═ 2, 4 CMR resources may also be taken in sequence from back to front and paired two by two in sequence, and of course, the CMR resources in the corresponding positions may also be paired in other predefined sequences and pairing rules.
In one embodiment, in a set low frequency band, a measurement reference signal resource with a pairing relationship is associated with a single transmission receiving node; in the set high frequency band, the measurement reference signal resources with the pairing relationship do not support the single transmission receiving node.
In this embodiment, in the low frequency band, the measurement reference signal resource having the pairing relationship supports association with STRP, that is, one CMR resource may be paired with other CMR resources, or may not be paired, for example, CMR3 in table 2; in setting the high frequency band, the measurement reference signal resources having a pairing relationship do not support being associated with STRP, i.e., one CMR resource cannot be associated with MTRP and STRP at the same time. In an embodiment, the reference signal measurement resources having a pairing relationship among the M reference signal measurement resources satisfy a predefined relative order relationship.
In this embodiment, the predefined relative order relationship includes: the reference signal measurement resources with the pairing relationship are adjacent, and are positioned at the front end, the rear end, the middle or two sides in the reference signal measurement resource configuration; alternatively, the first and second electrodes may be,
the reference signal measurement resources with the pairing relation are positioned in front of, behind, in the middle of or on two sides of the unpaired reference signal measurement resources;
correspondingly, the CMR resources having a pairing relationship are located in the buffer at the left side, the right side, the middle side or both sides of the buffer, or at the left side, the right side, the middle side or both sides of the unpaired CMR resources.
In one embodiment, the predefined relative order relationship comprises:
the reference signal measurement resources with the pairing relationship are adjacent and located in front of or behind or in the middle of or on both sides of the reference signal measurement resource configuration or unpaired reference signal measurement resources in the M reference signal measurement resources.
Fig. 3 is a diagram illustrating a relative order of reference signal measurement resources according to an embodiment. In this embodiment, when receiving the beams of TRP1 and TRP2, the UE stores the paired CMR resources in the left side of the buffer in the order from right to left, and stores the unpaired CMR resources in the right side of the buffer in the order from left to right. As shown in FIG. 3, the CMR resources shown in the shaded area represent the paired CMR resources. [ beam3, beam5], [ beam4, beam6] form two paired beam pairs, and beam1, beam2, beam7, beam8 do not perform beam pairing, so that CMR3, CMR5, CMR4, CMR6 are sequentially stored from the middle of the buffer to the left; the CMR1, CMR2, CMR7 and CMR8 are stored in order from the middle of the buffer to the right.
On the basis of fig. 3, if N is 2, the UE sequentially takes the first 4 CMRs from front to back in the CMR resources and pairs them to obtain { [ CMR6, CMR4], [ CMR5, CMR3] } associated MTRP, and the remaining CMR resources { CMR1, CMR2, CMR7, CMR8} associated STRP.
Fig. 4 is a diagram illustrating a relative order of reference signal measurement resources according to another embodiment. As shown in fig. 4, when the UE receives the beams of TRP1 and TRP2, the paired CMR resources may be sequentially stored on the left side of the buffer in the order from left to right, and the unpaired CMR resources may be sequentially stored on the right side of the buffer in the order from left to right.
It will be appreciated that in some embodiments, paired CMR resources may also be stored sequentially on the right side of the buffer, and unpaired CMR resources may also be stored sequentially on the left side of the buffer.
Fig. 5 is a diagram illustrating a relative order of reference signal measurement resources according to yet another embodiment. In this embodiment, the UE may symmetrically store the paired CMR resources at both sides of the buffer, and store the unpaired CMR resources in the middle of the buffer. As shown in FIG. 5, the CMR resources shown in the shaded area represent the paired CMR resources. For example, [ beam3, beam5], [ beam4, beam6] form two paired beam pairs, beam1, beam2, beam7, beam8 do not perform beam pairing, then CMR3 and CMR5 are stored in the first and last bits of the buffer, CMR4, CMR6 are stored in the second and penultimate bits of the buffer; CMR1, CMR2, CMR7, CMR8 are stored in the middle of the buffer.
Fig. 6 is a diagram illustrating a relative order of reference signal measurement resources according to yet another embodiment. As shown in fig. 6, when receiving the TRP1 and TRP2 beams, the UE may store the paired CMR resources symmetrically in the middle of the buffer and store the unpaired CMR resources on both sides of the buffer.
Fig. 7 is a diagram illustrating a relative order of reference signal measurement resources according to yet another embodiment. In this embodiment, if a CMR resource is associated with both STRP and MTRP, the CMR resource may be stored on both the left and right sides of the buffer. As shown in FIG. 7, the CMR resources shown in the shaded area represent the paired CMR resources, stored on the left side of the buffer, and the CMR resources shown in the unshaded area are stored on the right side of the buffer. The CMR3 resource is associated with both the STRP and the MTRP, in this case, the CMR resource in the CSI report feedback setting is { CMR6, CMR4, CMR5, CMR3, CMR3, CMR1, CMR2, CMR7, CMR8}, and CMR3 is stored on both sides of the buffer at the same time. On the basis, according to the condition that N is 2, the UE can sequentially pair every two of the first 4 CMR resources from front to back in the CMR resources to obtain { [ CMR6, CMR4], [ CMR5, CMR3] } associated MTRP, and the rest CMR resources { CMR3, CMR1, CMR2, CMR7, CMR8} associated STRP, wherein CMR3 is associated with both STRP and MTRP.
In one embodiment, the method further comprises:
step 130: and determining the number of bits of the CRI according to the number M of the reference signal measurement resources and the number N of the resource pairs with the pairing relation in the set high-frequency band.
In this embodiment, for setting the high frequency band FR2, each reference signal measurement resource is only associated with STRP or only associated with MTRP, in this case, the UE measures M measurement reference signal resources and resource Configuration signaling transmitted by two TRPs according to two Transmission Configuration Indicators (TCIs), so as to determine the number N of resource pairs having a pairing relationship, and determine CSI and the number of bits of CRI according to M and N.
In an embodiment, the CSI includes a CRI for indicating one of M reference signal measurement resources or one of N resource pairs having a pairing relationship; the CRI occupies at least

And (4) a bit.
In an embodiment, the value of N may be smaller than the number of resource pairs actually having a pairing relationship, in which case part of the CMR resources with interference may be ignored by the UE. For example, when [ beam3, beam5], [ beam4, beam6] form two paired beam pairs, if N is configured to be 1, the following CMR resources { CMR1, CMR2, [ CMR3, CMR5], and CMR4} are obtained in the CSI reporting feedback setting of TRP1, and at this time, the interference resource of TRP2 to TRP1 is obtained as CMR 5. Since N is 1, the interference resource CMR6 of TRP2 to TRP1 is ignored. Similarly, the following CMR resources { [ CMR5, CMR3], CMR6, CMR7, and CMR8} are obtained in the CSI reporting feedback setting of the TRP2, the interference resource obtained from the TRP1 to the TRP2 is CMR3, and the interference resource CMR4 from the TRP2 to the TRP1 is ignored because N ═ 1.
In an embodiment, the reference signal measurement resources having the pairing relationship correspond to the same CSI reporting feedback setting, or the same reference signal measurement resource configuration, or the same reference signal measurement resource set.
In this embodiment, the UE stores the reference signal measurement resources having the pairing relationship in the same CSI reporting feedback setting for reporting.
In an embodiment, the reference signal measurement resources having the pairing relationship correspond to different CSI reporting feedback settings, or different reference signal measurement resource sets.
In this embodiment, the UE stores the reference signal measurement resource having the pairing relationship in two CSI reporting feedback settings for reporting. And at the base station side, configuring the ID of the CMR resource of another TRP for the CMR resource set by the CSI reporting feedback to explicitly indicate that the two CMR resources have interference. In addition, the reconfiguration parameter N may be used to indicate the number of pairs of CMR resources in the CSI reporting feedback setting, and if there is no CMR resource to be paired, N is 0.
For example, beams transmitted by the TRP1 are beam1, beam2, beam3 and beam4, and corresponding CMR resources are CMR1, CMR2, CMR3 and CMR 4; beams transmitted by the TRP2 are beam5, beam6, beam7 and beam8, and corresponding CMR resources are CMR5, CMR6, CMR7 and CMR8, wherein [ beam3, beam5], [ beam4 and beam6] are two groups of paired beam pairs. beam1, beam2, beam7, beam8 were not beam paired. In the CSI reporting feedback setting of the TRP1, N is 2, and association relations are respectively established between CMR5 and CMR6 and CMR3 and CMR4 of the TRP 1.
In an embodiment, in each CSI reporting feedback setting, or in each reference signal measurement resource set, it is satisfied that: the first N reference signal measurement resources are in one-to-one correspondence and have a pairing relationship; or, the last N reference signal measurement resources are in one-to-one correspondence and have a pairing relationship.
Fig. 8 is a diagram illustrating a channel sounding reference signal resource configuration according to an embodiment. As shown in fig. 8, the pairing relationship between TRP1 and the CMR Resource in TRP2 may be established at a Report Setting Level (Report Setting Level), a Resource Setting Level (Resource Setting Level), or a Resource Set Level (Resource Set Level).
And establishing an association relationship between CMR3, CMR5 and CMR4, CMR6 by respectively matching the IDs of CMR5 and CMR6 indicated on the report setting2 and the IDs of CMR3 and CMR4 indicated on the report setting 1.
The association relationship between CMR3, CMR5 and CMR4, CMR6 is established at the resource setting level, namely, the IDs of CMR5 and CMR6 indicated on resource setting2 are respectively arranged below CMR3 and CMR4 indicated on resource setting 1.
The association relationship between CMR3, CMR5 and CMR4, CMR6 is established at the resource set level by matching the IDs of CMR5 and CMR6 indicated on resource set2 below CMR3 and CMR4 indicated on resource set1, respectively.
On this basis, the following CMR resources { CMR1, CMR2, [ CMR3, CMR5], [ CMR4, CMR6] } can be obtained in the CSI reporting feedback setting of the TRP 1. Therefore, interference resources of TRP2 on TRP1 are CMR5 and CMR 6.
Similarly, the following CMR resources { [ CMR5, CMR3], [ CMR6, CMR4], CMR7, and CMR8} can be obtained in the CSI reporting feedback setting of TRP 2. Therefore, interference resources of TRP1 on TRP2 are CMR3 and CMR 4.
In an embodiment, of two reference signal measurement resources having a pairing relationship, a first reference signal measurement resource is used for channel measurement, and a second reference signal measurement resource is a second type of channel state information reference signal with non-zero power and is used for interference measurement.
In this embodiment, the UE reports the two sets of CMRs associated with the MTRP in two CSI reporting feedback settings, respectively. And at the base station side, configuration of a second type of channel state information reference signal is additionally added in two CSI reporting feedback settings respectively for implicitly indicating that another CMR belongs to interference. The first non-zero power reference signal measurement resource is a traditional CSI-RS, and is used for measuring the interference of other users in a cell where the UE is located; the added second type of non-zero power reference signal measurement resource is a second type of channel state information reference signal, CSI-RS, for measuring interference from another TRP.
Fig. 9 is a diagram of an embodiment of a reference signal measurement resource configuration with increased non-zero power of a second type. As shown in fig. 9, the first CSI reporting feedback setting includes a CMR resource, a CSI-RS resource, and a CSI-IM resource, which are respectively used for channel measurement, intra-cell interference measurement, and inter-cell interference measurement. In the MTRP scenario, there is also inter-Port (Port) interference measurement in the presence of beam pairing, i.e. the CMR resource of one TRP may cause interference to the channel measurement of another TRP. In a second CSI reporting feedback setting, CSI-RS is additionally configured for measuring inter-port interference. Assume that beams transmitted by the TRP1 are beam1, beam2, beam3 and beam4, and the corresponding CMR resources are CMR1, CMR2, CMR3 and CMR 4. Beams transmitted by the TRP2 are beam5, beam6, beam7 and beam8, and corresponding CMR resources are CMR5, CMR6, CMR7 and CMR 8.
