[0123] Some of the CDM clusters in the multiple CDM clusters to which the multiple CSI-RS resources are mapped are configured in an interleaving manner, and the remaining CDM clusters are not configured in an interleaving manner.

[0124] All of the configurations of multiple CSI-RS resources using an interleaved manner may include, but are not limited to, at least one of the following:

[0125] All CSI-RS resources of the multiple CSI-RS resources are configured in an interleaving manner, and the remaining CSI-RS resources of the multiple CSI-RS resources are not configured in an interleaving manner.

[0126] All CDM clusters included in multiple CSI-RS resources are configured in an interleaving manner.

[0127] In some embodiments, configuring multiple CSI-RS resources using an interleaved manner may include at least one of the following:

[0128] Determine the frequency domain positions of multiple CSI-RS resources based on the interleaving method;

[0129] The time domain positions of multiple CSI-RS resources are determined based on the interleaving method.

[0130] In some embodiments, multiple CSI-RS resources are configured based on an interleaving pattern of designated resource elements.

[0131] In some embodiments, the number of REs included in a CSI-RS resource is equal to the number of antenna ports mapped to the CSI-RS resource.

[0132] In some embodiments, the designated resource unit may be a CSI-RS resource.

[0133] In some embodiments, the designated resource unit may be a CDM cluster.

[0134] In some embodiments, the designated resource unit may be a CDM group.

[0135] In some embodiments, the plurality of CSI-RS resources include one or more CDM clusters.

[0136] In some embodiments, configuring the plurality of CSI-RS resources using an interleaving manner may include configuring the plurality of CSI-RS resources based on an interleaving parameter.

[0137] In some embodiments, the interleaving parameters may include, but are not limited to, at least one of the following:

[0138] interweaving density;

[0139] interwoven sequences;

[0140] Interweaving type.

[0141] In some embodiments, the interleaving density may be the size of the interval between two designated resource units of adjacent resource indices.

[0142] In some embodiments, the interleaving sequence may be generated according to an interleaving density.

[0143] In some embodiments, different interleaving types correspond to different designated resource units. For example, interleaving based on CSI-RS resources and interleaving based on CDM clusters belong to different interleaving types.

[0144] Figures 1B to 1D show different types of CDM patterns. Different types of CDM patterns map CDM groups containing different numbers of REs. Different types of CDM patterns may include at least one of the following: CDM-2, CDM-4, ​​and CDM-8. In Figures 1B to 1D, one square represents one RE. In the CDM-2 pattern shown in Figure 1B, frequency division multiplexing is used between different REs in the CDM group mapped by the CDM pattern. In the CDM-4 pattern shown in Figure 1C, the CDM group mapped by the CDM-4 CDM pattern includes 4 REs. These 4 REs use both time division multiplexing and frequency division multiplexing. In the CDM-8 pattern shown in Figure 1D, the CDM group mapped by the CDM-8 pattern includes 8 REs. These 8 REs use both time division multiplexing and frequency division multiplexing.

[0145] In some embodiments, the plurality of CSI-RS resources may include one or more CDM clusters.

[0146] In some embodiments, one CSI-RS resource may be mapped to one or more CDM clusters.

[0147] In one embodiment, a CDM cluster includes at least one CDM group, that is, a CDM cluster may include one or more CDM groups.

[0148] In some embodiments, when a CDM cluster includes multiple CDM groups, these CDM groups may correspond to the same CDM pattern.

[0149] Exemplarily, when the number of antenna ports P mapped to a CSI-RS resource is equal to 32, the number of REs included in the CSI-RS resource is equal to 32. If a CSI-RS resource may include 16 CDM-2s, or a CSI-RS resource may include 4 CDM clusters.

[0150] In some embodiments, when multiple CSI-RS resources are configured using an interleaving manner, the multiple CSI-RS resources are configured according to an interleaving granularity.

[0151] In some embodiments, the interleaving granularity p may be equal to any positive integer greater than or equal to 1.

[0152] The CSI-RS resources are configured in an interleaving manner according to an interleaving granularity p, and designated resource units with adjacent indexes in multiple CSI-RS resources are spaced apart by p designated resource units in the frequency domain and / or time domain.

[0153] In some embodiments, when multiple CSI-RS resources are configured using an interleaving manner, the multiple CSI-RS resources are configured according to an interleaving sequence.

[0154] In some embodiments, the interleaving sequence includes multiple elements, each of which corresponds to a resource index of a specified resource unit. The position of the element corresponding to the resource index in the interleaving sequence can be used to determine the resource position of the specified resource unit indicated by the resource index.

[0155] In some embodiments, the interleaving sequence is generated according to an interleaving granularity.

[0156] In some embodiments, the interleaving sequence is selected from a set of candidate sequences.

[0157] In some embodiments, multiple CSI-RS resources are configured based on an interleaving manner of CSI-RS resources. In this case, the resources are interleaved according to the resource index of the CSI-RS resources. For example, when multiple CSI-RS resources are configured without an interleaving manner, the multiple CSI-RS resources can be mapped to the frequency domain and / or time domain in the order of the resource index. When multiple CSI-RS resources are configured in an interleaving manner, the multiple CSI-RS resources can be mapped to the frequency domain and / or time domain according to the interleaving sequence. The interleaving sequence is used to disrupt the resource indexes of multiple CSI-RS resources. The multiple CSI-RS resources are mapped to the frequency domain and / or time domain in a disordered order of the resource indexes using an interleaving manner.

[0158] As shown in Figure 2B , there are four CSI-RS resources with resource indices of 1 to 4. When multiple CSI-RS resources are configured using interleaving sequences of 1, 3, 2, and 4, the four CSI-RS resources are mapped to the frequency domain in the order of resource indices 1, 3, 2, and 4, rather than in the order of 1, 2, 3, and 4.

[0159] In some embodiments, multiple CSI-RS resources are configured based on an interleaving manner of code division multiplexing (CDM) clusters.

[0160] In some embodiments, if multiple CSI-RS resources are configured based on the interleaving method of CDM clusters, multiple CDM clusters of one CSI-RS resource can be interleaved and mapped to the frequency domain and / or time domain, thereby achieving finer-grained resource interleaving.

[0161] In some embodiments, multiple CSI-RS resources are configured based on an interleaving pattern between different CDM groups within a CDM group.

[0162] For example, if a CSI-RS resource includes N CDM groups corresponding to CDM-x, these N CDM groups are mapped to the frequency domain and / or time domain in an interleaved manner. N can be any positive integer.

[0163] For example, if the multiple CSI-RS resources include M CDM groups corresponding to CDM-x, the M CDM groups are mapped to the frequency domain and the time domain in an interleaved manner. M may be a positive integer.

[0164] For example, if the M CDM groups of the plurality of CSI-RS resources are continuously distributed in the frequency domain or continuously distributed in the time domain, in some embodiments, CDM-x may be CDM-2, CDM-4 and / or CDM-8, etc.

[0165] In some embodiments, multiple CSI-RS resources correspond to the same type of CDM pattern, and CDM groups with the same resource index of the multiple CSI-RS resources belong to the same CDM cluster.

[0166] For a CSI measurement of 64 ports, a network device can configure four CSI-RS resources. If CDM groups with the same resource index within multiple CSI-RS resources are grouped into one CDM cluster, these four CSI-RS resources can be divided into two CDM clusters, and one CDM cluster can include four CDM groups. These two CDM clusters are CDM Cluster 0 and CDM Cluster 1.

[0167] Frequency-domain interleaving is not performed for the different CDM groups within CDM cluster 0, but frequency-domain interleaving is performed for the different CDM groups within CDM cluster 1. The resulting image of these four CSI-RS resources is shown in Figure 2C. Interleaving the different CDM groups within CDM cluster 1 using interleaving sequences 1, 3, 2, and 4 results in the frequency-domain ordering of the four CDM groups within CDM cluster 1 being CDM group 1, CDM group 3, CDM group 2, and CDM group 4.

[0168] In some embodiments, if multiple CSI-RS resources correspond to two or more CDM patterns, CDM groups mapped to the same CDM pattern in the multiple CSI-RS resources can be assigned to one CDM cluster. The CSI-RS resources are configured based on the interleaving of different CDM groups within the CDM cluster in the frequency and / or time domains.

[0169] For a CSI measurement of 64 antenna ports, 4 CSI-RS resources can be configured, and these 4 CSI-RS resources contain 2 CDM clusters corresponding to CDM-8, and the cluster indices of these two CDM clusters are 0 and 1, respectively. When configuring CSI-RS resources, frequency domain interleaving mapping is first performed between the 4 CSI resources, and then frequency domain interleaving mapping is performed between different CDM groups within the CDM cluster. The effect diagram can be shown in Figure 2D. In Figure 2D, REs with the same filling belong to one CSI-RS resource, and CDM groups at different time domain positions belong to different CDM clusters. As shown in Figure 2D, the 4 CSI-RS resources are first interleaved in the frequency domain according to interleaving sequences 1, 3, 2, and 4, and then the CDM groups within the CDM cluster are interleaved for CDM cluster 1.

[0170] In some embodiments, if multiple CSI-RS resources include multiple CDM clusters, the interleaving sequences of the multiple CDM clusters may be different, so that the resource positions of CDM groups of the same CSI-RS resources in different CDM clusters are different, thereby obtaining better channel measurement results.

[0171] In some embodiments, at least some of the CSI-RS resources among the multiple CSI-RS resources are adjacent in the frequency domain; and / or, at least some of the CSI-RS resources among the multiple CSI-RS resources are adjacent in the time domain, and / or, the CDM groups included in at least some of the CDM clusters of the multiple CSI-RS resources are adjacent in the frequency domain, and / or, the CDM groups included in at least some of the CDM clusters of the multiple CSI-RS resources are adjacent in the time domain.

[0172] In some embodiments, at least some of the multiple CSI-RS resources being frequency-domain adjacent may include: the multiple CSI-RS resources being frequency-domain adjacent; and / or some of the multiple CSI-RS resources being frequency-domain adjacent.

[0173] In some embodiments, the time domain proximity of at least some of the multiple CSI-RS resources may include: the time domain proximity of the CDM groups included in each CDM cluster of the multiple CSI-RS resources; and / or the time domain proximity of the CDM groups included in some of the CDM clusters of the multiple CSI-RS resources.

[0174] In some embodiments, the frequency domain proximity of the CDM groups included in at least some CDM clusters of multiple CSI-RS resources may include: the frequency domain proximity of the CDM groups included in each CDM cluster of multiple CSI-RS resources; and / or, the frequency domain proximity of the CDM groups included in some CDM clusters of multiple CSI-RS resources.

[0175] In some embodiments, CDM groups within one or more CDM clusters of multiple CSI-RS resources are adjacent in frequency domain, and / or CDM groups within one or more CDM clusters of multiple CSI-RS resources are adjacent in time domain.

[0176] In some embodiments, multiple CDM groups within a CDM cluster have the same frequency domain position or the same time domain position.

[0177] For example, multiple CDM groups within a CDM cluster have the same frequency domain position and different time domain positions.

[0178] For another example, multiple CDM groups within a CDM cluster have the same time domain position and different frequency domain positions.

[0179] In some embodiments, multiple CDM groups within a CDM cluster having the same frequency domain location may include but are not limited to at least one of the following:

[0180] Multiple CDM groups within a CDM cluster have the same subcarriers;

[0181] Multiple CDM groups within a CDM cluster are located in the same RB;

[0182] Multiple CDM groups in a CDM cluster are located in the same RE.

[0183] In some embodiments, multiple CDM groups within a CDM cluster having the same time domain location may include but are not limited to at least one of the following:

[0184] Multiple CDM groups in a CDM cluster have the same time slot;

[0185] Multiple CDM groups in a CDM cluster have the same mini-time slot;

[0186] The orthogonal frequency division multiplexing (OFDM) symbols of multiple CDM groups in a CDM cluster are the same.

[0187] In some embodiments, multiple CDM groups within a CDM cluster are adjacent in frequency domain but have corresponding orthogonal frequency division multiplexing (OFDM) symbols that are the same.

[0188] In some other embodiments, multiple CDM groups within a CDM cluster are adjacent in time domain but have the same corresponding RBs or REs.

[0189] In some embodiments, CDM groups in different CDM clusters are adjacent in the frequency domain and / or in the time domain.

[0190] Of course, in other embodiments, the CDM groups of different CDM clusters may be separated in the frequency domain and / or the time domain.

[0191] If the resource locations of multiple CSI-RS resources are adjacent in the frequency domain, the frequency points used by the multiple CSI-RS resources are the same or similar, which can improve the channel correlation and thus improve the channel measurement quality.

[0192] If the resource locations of multiple CSI-RS resources are adjacent in the time domain, the multiple CSI-RS resources involved in one CSI measurement can be measured within a short continuous time, thereby improving the channel correlation and further improving the channel measurement quality.

[0193] In some embodiments, the multiple CSI-RS resources are from one or more CSI-RS resource sets.

[0194] In some embodiments, a CSI-RS resource set may include one or more candidate CSI-RS resources.

[0195] In some embodiments, the designated resource parameters of each candidate resource in a CSI-RS resource set are the same.

[0196] In some embodiments, the specified resource parameters include but are not limited to at least one of the following:

[0197] The number of mapped ports, frequency domain density, starting position of resource blocks (RBs), number of RBs, and CDM pattern.

[0200] In some embodiments, the multiple CSI-RS resources come from different CSI-RS resource sets, and at least one of the number of ports mapped to each CSI-RS resource in the multiple CSI-RS resources, the frequency domain density, the starting position of the resource block RB, the bandwidth, the subcarrier position, the time slot, the RE position, and the CDM pattern is different.

[0201] In some embodiments, the number of ports mapped to a CSI-RS resource is: the number of antenna ports that can be used to measure the CSI-RS sent in one CSI-RS resource.

[0202] In some embodiments, the frequency domain density may be: the number of resource blocks (RBs) to which the number of REs corresponding to one antenna port belongs.

[0203] In some embodiments, an RB is also called a physical resource block (PRB).

[0204] The starting RB position of a CSI-RS resource may be the RB where the RE with the smallest index occupied by the CSI-RS resource in the frequency domain is located.

[0205] The number of RBs of a CSI-RS resource may be the number of RBs to which REs included in the CSI-RS resource belong.

[0206] Different CDM patterns of a CSI-RS resource mapping include different CDM groups.

[0213] In some embodiments, the number of the first resource may be 1.

[0214] In some embodiments, the second resource may be other CSI-RS resources other than the first resource.

[0215] In some embodiments, the first resource may be the CSI-RS resource with the smallest resource index among multiple CSI-RS resources, the CSI-RS resource with the largest resource index among multiple CSI-RS resources, or a pre-agreed CSI-RS resource among multiple CSI-RS resources.

[0216] In some embodiments, the pre-agreed CSI-RS resources may be agreed upon by a protocol.

[0217] In some embodiments, the second information may enable configuration of multiple CSI-RS resources with a smaller bit overhead by indicating relative resource positions.

[0218] In some embodiments, the second information may be a frequency domain offset and / or a time domain offset. For example, the frequency domain offset indicates the relative position of the second resource relative to the first resource in the frequency domain. The time domain offset indicates the relative position of the second resource relative to the first resource in the time domain.

[0219] Exemplarily, the second information may include 1 or 2 positive integers.

[0220] In some embodiments, the third information may indicate an interleaving method used when configuring multiple CSI-RS resources, so that after receiving the configuration information, the terminal can determine the resource locations of all CSI-RS resources in combination with the resource location of the first resource.

[0221] In some embodiments, the third information may include an interleaving mode index. In this case, the third information may be a positive integer.

[0222] In other embodiments, the third information may be an interleaving parameter corresponding to the interleaving method.

[0223] In some cases, the configuration information may include fourth information. The fourth information may be used for relative resource positions of the plurality of CSI-RS resources relative to the designated resource.

[0224] The designated resource may be a resource agreed upon in a protocol. The designated resource may belong to multiple CSI-RS resources or may not belong to multiple CSI-RS resources.

[0230] In some embodiments, the interleaving mode may be divided into a CSI-RS resource-based interleaving mode and a CDM cluster-based interleaving mode according to the size of the designated resource unit used in the interleaving mode.

[0243] Multiple CSI-RS resources correspond to multiple types of CDM patterns. CDM groups corresponding to the same type of CDM pattern in multiple CSI-RS resources belong to the same CDM cluster; CDM groups corresponding to different types of CDM patterns have different numbers of resource units RE.

[0244] In other embodiments, when multiple CSI-RS resources are configured in an interleaving manner based on code division multiplexing (CDM) clusters, different CDM clusters correspond to different interleaving sequences.

[0259] In some embodiments, optional implementations of S3102 may refer to S2102 of the embodiment corresponding to FIG. 2A .

[0260] In some embodiments, S3101 is an optional step. For example, the configuration operation of multiple CSI-RS resources can be completed by other network devices, and the current network device can directly send the configuration information of the CSI-RS resources received from the other network devices. For example, for a dual-connected terminal, the terminal's primary node can complete the configuration of the CSI-RS resources. The primary node transmits the configuration information to the terminal's secondary node, and the secondary node sends the configuration information received from the primary node.

[0267] In some embodiments, multiple CSI-RS resources are configured using an interleaving manner.

[0268] In some embodiments, the multiple CSI-RS resources are configured based on interleaving parameters. The multiple CSI-RS resources configured based on interleaving parameters are CSI-RS resources configured in an interleaving manner.

[0269] In some embodiments, the interleaving parameters include, but are not limited to, at least one of the following:

[0270] interweaving type;

[0271] interweaving density;

[0272] Interleaved sequences, etc.

[0273] In some embodiments, multiple CSI-RS resources are configured based on an interleaving manner of CSI-RS resources; and / or, multiple CSI-RS resources are configured based on an interleaving manner of code division multiplexing (CDM) clusters; and multiple CSI-RS resources include one or more CDM clusters.

[0274] In some embodiments, multiple CDM groups of a CDM cluster correspond to the same CDM pattern.

[0275] In some embodiments, the interleaving manner of the CDM cluster may be an interleaving manner between CDM groups based on the same CDM cluster.

[0276] A CDM cluster includes one or more CDM groups corresponding to the same CDM pattern.

[0277] Multiple CDM groups within a CDM cluster have the same time domain position; or, multiple CDM groups within a CDM cluster have the same frequency domain position.

[0278] In some embodiments, multiple CSI-RS resources correspond to the same type of CDM pattern, and CDM groups with the same resource index in the multiple CSI-RS resources belong to the same CDM cluster. In some embodiments, multiple CSI-RS resources correspond to different types of CDM patterns, and CDM groups corresponding to the same type of CDM pattern in the multiple CSI-RS resources belong to the same CDM cluster; CDM groups corresponding to different types of CDM patterns have different numbers of resource elements (REs).

[0279] In some embodiments, when multiple CSI-RS resources are configured in an interleaving manner based on code division multiplexing (CDM) clusters, different CDM clusters correspond to different interleaving sequences.

[0280] In some embodiments, at least some of the CSI-RS resources among the multiple CSI-RS resources are adjacent in the frequency domain; and / or, at least some of the CSI-RS resources among the multiple CSI-RS resources are adjacent in the time domain, and / or, the CDM groups included in at least some of the CDM clusters of the multiple CSI-RS resources are adjacent in the frequency domain, and / or, the CDM groups included in at least some of the CDM clusters of the multiple CSI-RS resources are adjacent in the time domain.

[0281] In some embodiments, the multiple CSI-RS resources are from one or more CSI-RS resource sets.

[0282] In some embodiments, multiple CSI-RS resources come from the same CSI-RS resource set, and one or more of the number of ports mapped to each CSI-RS resource in the multiple CSI-RS resources, the frequency domain density, the starting position of the resource block RB, the bandwidth, the subcarrier position, and the CDM pattern are the same; and / or, the resource unit RE positions of the multiple CSI-RS resources in different time slots are the same.

[0283] In some embodiments, the multiple CSI-RS resources come from different CSI-RS resource sets, and at least one of the number of ports mapped to each CSI-RS resource in the multiple CSI-RS resources, the frequency domain density, the starting position of the resource block RB, the bandwidth, the subcarrier position, the time slot, the RE position, and the CDM pattern is different.

[0286] First information, used to indicate a first resource;

[0287] The second information is used to indicate a relative resource position between the second resource and the first resource;

[0289] Multiple CSI-RS resources for one CSI measurement are configured in an interleaved manner to support channel measurement of a larger antenna port while ensuring channel measurement accuracy.

[0290] The N (N>1) CSI-RS resource configurations for channel measurement can be as follows:

[0291] N CSI-RS resources with the same or different port numbers use the same or different CDM groups and come from M CSI-RS resource sets.

[0292] When M=1, the N CSI-RS resources have the same number of ports, density, RB starting position, number of RBs, and CDM pattern.

[0293] For N CSI-RS resources from M>1 CSI-RS resource sets, the number of ports, density, RB starting position, number of RBs, and CDM pattern of the N CSI-RS resources may be different or the same.

[0294] Configure N CSI-RS resources in an interleaved manner. The following options are provided:

[0296] The position indication of the CSI-RS resource mapped to the RE may include a position indicating a reference CSI-RS resource. For example, the position indication may be used to indicate the time-frequency domain position of the reference CSI-RS resource, and the time-frequency domain positions of the other N-1 CSI-RS resources are determined based on the time-frequency domain position of the reference CSI-RS resource and the interleaving method defined in the above-mentioned optional method 1.

[0300] An indication of the time-frequency domain location of the reference CSI-RS resource;

[0301] The time-frequency domain positions of the other N-1 CSI-RS resources are as indicated by the defined interleaving sequence;

[0305] All or part of the CSI-RS resources are adjacently arranged in the frequency domain and / or time domain.

[0306] At least some CDM groups with the same CSI-RS resource index are adjacently arranged in the frequency domain and / or time domain.

[0307] The position indication where the CSI-RS resource is mapped to the RE may include at least one of the following:

[0308] An indication of the time-frequency domain location of the reference CSI-RS resource;

[0309] The time-frequency domain positions of the other N-1 CSI-RS resources are as indicated by the defined interleaving sequence;

[0310] An indication of the time-frequency domain positions of the other N-1 CSI-RS resources relative to the reference CSI-RS resource.

[0311] In some embodiments, the location indication here may be composed of specific information of the aforementioned configuration information.

[0312] The following are some specific configuration examples:

[0313] Example 1:

[0314] Assume that the base station configures four CSI-RS resources for the terminal, the number of ports mapped to each CSI-RS resource is P = 16, and the CDM pattern is CDM-8. These four CSI-RS resources come from the same CSI-RS resource set. Therefore, these four resources have the same number of ports, CSI-RS resource density, CDM pattern, RB starting position, and bandwidth.

[0315] Assume that the configured CSI-RS resource identifications (IDs) are 0, 1, 2, and 3, respectively. The CSI-RS resources are indexed as 1, 2, 3, and 4 in order of the resource IDs, and the resource with the smallest ID (i.e., the first CSI-RS resource) is defined as the reference resource.

[0316] For the N=4 CSI-RS resources, two CSI-RS resources are adjacent in the frequency domain, and the CSI-RS resources are interleaved with an interleaving density of ρ=1. That is, the interleaving sequences of the four CSI-RS resources indexed 1, 2, 3, and 4 are 1, 3, 2, and 4, as shown in FIG2B .

[0317] If the number of configured CSI-RS resources N = 8, the CSI-RS resources can be interleaved with an interleaving density of ρ = 2 to achieve 8 CSI-RS resources. That is, the interleaving sequences of the 8 CSI-RS resources indexed as 1, 2, 3, 4, 5, 6, 7, and 8 are defined as 1, 2, 5, 6, 3, 4, 7, and 8.

[0318] The base station can indicate the time-frequency domain position of the first CSI-RS resource through the RRC message. Since the CDM pattern of these four resources is the same and these CSI-RS resources are adjacent to each other in the frequency domain, once the interleaving sequence of the CSI-RS resources is determined, the frequency domain positions of the remaining three CSI-RS resources can also be determined, and the time domain positions are the same as the time domain positions of the reference resources.

[0319] Example 2:

[0320] Assume that the base station configures four CSI-RS resources for the terminal, each CSI-RS resource is mapped to 16 ports, and the CDM pattern is CDM-8. Furthermore, these four CSI-RS resources come from the same CSI-RS resource set. Therefore, these four resources have the same number of ports, CSI-RS resource density, CDM pattern, RB starting position, and bandwidth. In the disclosed embodiments, resource interleaving is performed using CDM clusters.

[0321] Based on the above configuration, the multiple CSI-RS resources configured at once include two CDM clusters, defined as indexes 0 and 1. CDM cluster indexed 1 undergoes CDM group-based interleaving, and the four CDM groups within this cluster are interleaved. Assuming interleaving density ρ = 1, the interleaving sequences are defined as 2, 1, 4, and 3. The multiple CDM groups within the CDM cluster indexed 0 are not interleaved, as shown in Figure 2C.

[0322] The base station can indicate the time-frequency domain starting position of the reference resource through an RRC message. The time-frequency domain positions of the other three resources can be determined based on the reference time-frequency domain position. For example, the time domain positions of the other three resources (including the time domain positions of each CDM) are consistent with the time domain position of the reference resource, while the frequency domain positions can be determined based on the interleaving sequences used by different CDM clusters and their frequency domain proximity.

[0323] Example 3:

[0324] Assume that the base station configures four CSI-RS resources for the terminal, with each CSI-RS resource mapped to 16 ports (P) and a CDM pattern of CDM-8. These four CSI-RS resources are from the same CSI-RS resource set. Therefore, these four resources have the same number of ports, CSI-RS resource density, CDM pattern, RB starting position, and bandwidth. CDM groups with the same resource index belong to the same CDM cluster, resulting in two CDM clusters: CDM0 and CDM1.

[0325] In the disclosed embodiments, CSI-RS resources are configured using two interleaving methods: CSI-RS resource interleaving and CDM group interleaving within a CDM cluster. First, four CSI-RS resources are interleaved in the interleaving sequence of 1, 3, 2, and 4. Then, the CDM group with index 0 is interleaved in the sequence of 1, 2, 3, and 4, while the CDM group with index 1 is interleaved in the sequence of 2, 1, 4, and 3. This is shown in Figure 2D.

[0326] The base station indicates the starting time-frequency domain position of the reference resource through an RRC message. The time-frequency domain positions of the other three resources can be determined based on the reference time-frequency domain position. For example, the time domain positions of the other three resources (including the time domain positions of each CDM) are determined by the time domain position of the reference resource, while the frequency domain positions are determined by the interleaving sequence of the CSI-RS resource and the interleaving sequences used by different CDM clusters.

[0327] In summary, the N>1 CSI-RS resource configuration method can reduce signaling indication overhead and ensure that the terminal is based on the interleaved CSI-RS configuration, improve the correlation between the policy ports, obtain more accurate channel measurements, and thus improve system performance.
