 FIG. 1 is a flowchart of an embodiment of a resource allocation method provided by the present invention. As shown in FIG. 1, the method includes:

 5101. The first central controller acquires configuration information of a resource set corresponding to the CID according to the group identifier CID of the coordinated multi-point CoMP set, where the CoMP set includes at least one node, where the resource set includes at least one first resource, and configuration information of the resource set. The configuration information of the at least one first resource is included.

 The first central controller sends the configuration information of the at least one first resource in the resource set to the user equipment, so that the user equipment determines the at least one first resource according to the configuration information of the at least one first resource, and performs the first resource by using the first resource. measuring.

 A CoMP set may include at least one node, and a node involved in all embodiments of the present invention may also refer to a cell. All nodes in a CoMP set can be controlled by a central controller. The central controller may be a base station or other network node, or the central controller may be a unit or module in the base station or other network node.

The first resource may be configured with the corresponding configuration information for each of the first resources, or may be configured with the corresponding configuration information for the first resource. The different first resources may be configured with the same configuration information, or may be configured differently. Configuration information. In the embodiment of the present invention, each CoMP set corresponds to a cluster indicator (CID). When at least two nodes are included in the CoMP set, then these nodes all correspond to the CID of the CoMP set to which they belong.

 In the embodiment of the present invention, one CoMP set corresponds to one CID, and each CID corresponds to one resource set, and the resource set may include at least one first resource. Optionally, the first resource may be: an interference measurement resource IMR or a non-zero power channel-state information reference signal (NZP CSI-RS). It can be understood that the first resource involved in the present invention is not limited to IMR or NZP CSI-RS, and may be other resources.

 It should be noted that the CoMP set that is far away can use the same CID, and because the CoMP set is far away, even if the two CoMP sets use the same resource set, it will not cause a large mutual influence. That is to say, the resource set can be reused between CoMP sets that are distant from each other in the network.

 In the embodiment of the present invention, all available first resources, for example: IMR or NZP CSI-RS, may be divided into multiple resource sets, each resource set corresponding to one CID, and each CoMP set corresponds to one CID, so that the CoMP set Each node in the pair corresponds to a CID, and the resource set used in the CoMP set is a resource set corresponding to the CID.

 The CID of the CoMP set may be configured to the cell or the node or the base station corresponding to the CoMP set, and the central controller determines the resource set corresponding to the CID by the CID corresponding to the cell or node or the base station corresponding to the CoMP set; or the CID corresponding to the CoMP set may be directly Configured to the central controller, then the central controller CID determines the corresponding set of resources.

 It should be noted that when at least two first resources are included in one resource set, at least two first resources are orthogonal to each other.

The first resource may have multiple patterns, such as a pattern of multiple first resources in a physical resource block (PRB) pair (pair), for example, the implementation of the first resource in the IMR. In a scenario, a PRB pair may include a pattern of 20 IMRs numbered 0 to 19, according to which the resource set may be divided according to the pattern number of the first resource. For example: Each of the five numbered IMR patterns can be divided into one resource set, and the IMR pattern numbered 0-4 can be divided into one resource set, and the IMR pattern numbered 5-9 can be divided into one resource set. analogy. In the division mode of such a resource set, all the first resources in the resource set The subframe configuration may be corresponding to the subframe configuration, and the subframe configuration includes: a subframe period and an offset position of the subframe in which the resource set is located in the subframe period. For example, if the subframe period is 5, the offset position of the subframe in which the resource set is located in the period may be 0-4.

 As a possible implementation manner, the configuration information of the resource set may include: a pattern number of the at least one first resource included in the resource set, and subframe configuration information of the resource set, where the subframe configuration information includes a subframe period and a resource. The offset position of the subframe in which the collection is located in the subframe period.

 After the first central controller acquires the configuration information of the corresponding resource set according to the CID of the CoMP set, the first central controller may send configuration information of the at least one first resource in the resource set to the user equipment, so that the user equipment is configured according to at least one The configuration information of the first resource determines at least one first resource, and performs measurement by using the first resource.

 The first central controller may send configuration information of the at least one first resource to the user equipment by using the serving cell or the serving base station of the user equipment, or the first central controller directly sends configuration information of the at least one first resource to the user equipment. The serving cell of the user equipment may be a cell that provides a data transmission service for the user equipment or a cell that transmits control information to the user equipment. The serving cell of the user equipment may be a cell in a CoMP set providing data transmission services for the user, or may be another cell. It should be noted that one UE may use one or more first resources in the resource set corresponding to the CoMP set. For example, if the first set of resources is included in the resource set, the UE may use one or two of the first resources.

 It can be understood that the configuration information of the resource set may include: a pattern number of the at least one first resource included in the resource set and subframe configuration information of the resource set. Therefore, the configuration information of the first resource sent by the first central controller to the user equipment may be: a pattern number of the first resource and subframe configuration information of the first resource, where the subframe configuration information of the first resource includes a subframe period and The subframe in which the first resource is located is at an offset position within the period.

 As another possible implementation manner, all available or used first resources may also be numbered, for example, all first resources having the same or different subframe configurations may be numbered. In this implementation scenario, the configuration information of the resource set may be: a number of at least one first resource included in the resource set. Correspondingly, the configuration information of the first resource sent by the first central controller to the user equipment may be: a number of the first resource, to enable the user equipment to determine the at least one first resource according to the configuration information of the at least one first resource, and pass the The first resource is measured.

In the embodiment of the present invention, the method for determining, by the user equipment, the first resource number and the network side node are The method of determining the first resource number is the same, so that the user equipment may determine related configuration information of the first resource according to the number of the first resource, for example: determining a pattern of the first resource according to the number of the first resource, or determining the first resource. Pattern and subframe configuration. The determining of the first resource number may be performed by using a predefined method, or may be notified to the user equipment by the serving cell of the user equipment. The pattern of the first resource may be a pattern in which the first resource hops or does not jump on different subframes.

 According to the resource allocation method provided by the embodiment of the present invention, a CID is configured for each CoMP set, and the central controller determines the resource set used by each CoMP set and the configuration information of the corresponding resource set according to the relationship between the resource set and the CID, and passes the serving cell. The configuration information of the at least one first resource in the corresponding resource set is sent to the user equipment, and the CID identifier used by the CoMP set is different from each other, so that the first resources used by the corresponding CoMP set can be coordinated with each other without overlapping Therefore, the complexity of the actual system resource allocation can be reduced, and the first resource allocated to different CoMP sets that are closer to each other can be easily avoided, and the accuracy according to the measurement of the first resource is ensured. 2 is a flowchart of still another embodiment of a resource allocation method according to the present invention. As shown in FIG. 2, the method includes:

 S201. The user equipment receives configuration information of at least one first resource in a resource set sent by the first central controller, where the resource set corresponds to a group identifier CID of the coordinated multi-point CoMP set to which the user equipment belongs, and the CoMP set includes at least one node. The resource set includes at least one first resource, and the configuration information of the resource set includes configuration information of the at least one first resource.

 S202. The user equipment determines the at least one first resource according to the configuration information of the at least one first resource, and performs measurement by using the first resource.

 The first central controller may allocate, for the UE in the CoMP set, at least one first resource in the resource set, and send configuration information of the first resource to the user equipment. The first resource may be an IMR or an NZP CSI-RS, and each resource set may include at least one first resource, or a partial resource set may include at least one first resource. The first resource in the present invention is not limited to IMR or NZP CSI-RS, and may be other resources.

In the present invention, one CoMP set corresponds to one CID, and one CID corresponds to one resource set, so that the resource set used by the CoMP set is the resource set corresponding to the CID. The resource collection here is the resource collection of the first resource. Specifically, the CoMP set of the serving cell of the user equipment or the cell that provides the data transmission service for the user equipment corresponds to a CID, and the CID corresponds to a resource set, so that the resource set used by the CoMP set is the resource corresponding to the CID. set.

 Optionally, the configuration information that the user equipment receives the first resource sent by the first central controller may be: a pattern number of the first resource and subframe configuration information of the first resource, where the subframe configuration information of the first resource includes The frame period and the offset position of the subframe in which the first resource is located within the period.

 Optionally, all first resources having the same or different subframe configurations may also be numbered, in this implementation scenario. The configuration information that the user equipment receives the first resource sent by the first central controller may be: a number of the first resource.

 After receiving the configuration information of the first resource sent by the first central controller, the user equipment may determine the first resource according to the configuration information of the first resource, and perform measurement on the resource. For example, in an implementation scenario where the first resource is an IMR, after the user equipment determines the IMR allocated by the first central controller, the interference can be measured on the IMR; in the implementation scenario where the first resource is the NZP CSI-RS, the user The device can perform channel measurement through the NZP CSI-RS.

 The resource allocation method provided by the embodiment of the present invention may configure one for each CoMP set.

The CID is configured to configure a CID for each CoMP set in the partial CoMP set, and the central controller determines the resource set used by the CoMP set and the configuration information of the corresponding resource set according to the relationship between the resource set and the CID, and sends the configuration information to the user equipment through the serving cell. The configuration information of the at least one first resource in the corresponding resource set is different, and the CID identifier used by the CoMP set is smaller than the CID identifier, so that the first resources used by the corresponding CoMP set can be coordinated and not overlapped with each other, thereby The complexity of the actual system resource allocation can be reduced, and the first resource allocated to different CoMP sets that are closer to each other can be easily avoided, and the accuracy according to the measurement of the first resource can be ensured. The present invention further provides another embodiment of the resource allocation method. In this embodiment, the configuration information of the resource set may include: a pattern number of at least one first resource included in the resource set, and subframe configuration information of the resource set, and a subframe configuration. The information includes the subframe position and the offset position of the subframe in which the resource set is located in the subframe period. Correspondingly, the configuration information of the first resource that is sent by the serving cell of the UE to the UE may include: a pattern number of the first resource and subframe configuration information of the first resource, where the subframe configuration information of the first resource includes a subframe period and a The offset of the subframe in which a resource is located during the period. Optionally, the mapping between the pattern number of the first resource and the CID in the resource set corresponding to the CID may be: X mod M=CID, where X is the pattern number of the first resource, CID is the value of the CID, and M is The maximum number of CIDs that can be used in the network.

 In this implementation scenario, correspondingly, the pattern number of the first resource may be determined by a CID, (X-CID)/M information, and a value of M corresponding to the resource set to which the first resource belongs, where X is the first resource. The pattern number, CID is the value of CID, and M is the maximum number of CIDs that can be used in the network. Wherein, M may be predefined or notified to the UE by the serving cell of the UE.

 Optionally, the first central controller may further obtain the integrated number, and obtain the CID by using the integrated number; wherein, the integrated number is a number according to different combinations of the CID and the subframe configuration information of the resource set. The correspondence between the integrated number and the CID may be: the integrated number is equal to (k-1) * the sum of the value of the CID and the subframe configuration number of the resource set, where k is the maximum value of the subframe configuration number, and the CID is the CID Value.

 In this implementation scenario, the configuration information of the first resource sent by the first central controller to the UE may include: determined by the integrated number of the resource set to which the first resource belongs and the (X-CID)/M information and the value of M a pattern number of the first resource, and subframe configuration information of the resource set, where X is a pattern number of the first resource, CID is a value of CID, and M is a maximum number of CIDs that can be used in the network. Where k and M are both predefined or notified to the UE by the serving cell of the UE. The present invention further provides another embodiment of the resource allocation method. In this embodiment, all the first resources are numbered for detailed description. This resource allocation method can be used in embodiments of the present invention. In this implementation scenario, the resource set can be uniformly divided among all the first resources.

 In this implementation scenario, the resource set may be composed of the first resource numbered X, and the number X of the first resource may be determined by the following formula: X=l_subframe*P+p, where P is the first resource The maximum number of patterns, p is the pattern number of the first resource, and l_subframe is the subframe configuration number of the first resource. For example, in the implementation scenario where the first resource is an IMR, the number of the subframe configuration may be 0-4, the corresponding subframe period is 5ms, and the offset position of the subframe in the period is 0-4. When P = 20, the period is 5 (the offset position of the subframe is 0-4 in the period), then the number of IMR in one cycle is 20 * 5 = 100.

Optionally, in the implementation scenario, the correspondence between the number of the first resource and the CID may be: floor (X/N)=CID, where X is the number of the first resource, and N is the Resource set The number of the first resources included in the combination, the CID is the value of the CID, and the floor ( ) indicates that the rounding operation is performed.

 For example, according to X = l_subframe*P + p, the first resource in one cycle can be numbered from 0 to 99. If the number of first resources included in the resource set is N=5, then the number is 0~4. The first resource is a resource set, the first resource numbered 5-9 is a resource set, and so on. In this implementation scenario, the first resource numbered 0 ~ 19, the first resource numbered 20 ~ 39, the first resource numbered 40 ~ 59, the first resource numbered 60 ~ 79, number 80 The first resources of ~99 are respectively located in the same subframe, and therefore have the same subframe configuration. Therefore, when N is 1/2/4/5/10/20, all the first resources in the resource set obtained according to floor(X/N)=CID have the same subframe configuration and can be allocated to one user equipment. For interference measurement, the subframe period can be 5ms.

 Since the resource set is uniformly numbered by all the first resources, the configuration information of the resource set corresponding to the CID of each or part of the CoMP set may be: the number of all the first resources included in the resource set. It can be understood that the configuration information of the first resource that is sent by the first central controller to the UE includes: a number of the first resource; or, a CI D and an X mod CI D corresponding to the resource set to which the first resource belongs Information and the number of the first resources included in the resource set to which the first resource belongs. Thus, the user equipment can obtain the number of the X first resource by CID*N+ ( X mod CID ) =X. In the present invention, N may be predefined or notified to the UE by the serving cell of the UE.

 Optionally, the resource set is divided into at least one resource subset, and the subframe configuration between the at least one resource subset may be different. Thus different subsets of resources included within a resource set can have different subframe configurations. The first central controller may allocate a resource subset to a user equipment. In an implementation scenario where the first resource is an IMR, each of the CoMP sets may have a plurality of different subframe configured resource subsets for interference measurement. .

 In this implementation scenario, the correspondence between the number of the first resource and the CID may be: floor ( X / ( N / T ) ) = SSID, where X is the first resource No. N is the number of the first resources included in the resource set, SSID mod M=CID, CID is the value of the CID, and M is the maximum number of the CIDs that can be used in the network, SSID The number of the resource subset.

Optionally, the first resource used in all networks may only be the first corresponding to the same subframe period. A resource, but the subframe offset position in the subframe configuration of each of the first resources may be different, and the subframe configuration number l_subframe may be replaced by the subframe offset position number l_offset.

 In the present invention, the method for the user equipment to determine the first resource number is the same as the method for the network side node to determine the first resource number, so that the user equipment can determine related configuration information of the first resource according to the number of the first resource, for example: a pattern, Or pattern and subframe configuration. The method for determining the first resource number is predefined or notified to the user equipment by the serving cell of the user equipment.

 Based on the foregoing embodiment, the first central controller may further send the CID of the CoMP set to the second central controller, where the second central controller may be a central controller that is closer to the first central controller. Or the adjacent central controller of the first central controller, and the specific first central controller may send the CID of the CoMP set to the second through a core network interface with the second central controller, for example: an X2 interface. a central controller, such that the second central controller coordinates the first resource of the second central controller according to the first resource of the first central controller, for example: the first CoMP set can be changed Or the CID corresponding to the second CoMP set, so that each CoMP set under the first central controller and the resource set used by each CoMP set under the second central controller are prevented from overlapping.

 It should be noted that the number of CIDs in the network may be determined according to the number of the largest first resource available or used. For example, if the maximum first resource number is NUM_MAX, the number of CIDs in the network may be a divisor of NUM_MAX.

 The present invention also provides another resource allocation method, in which the CID of the CoMP set can correspond to different resource sets in different first time periods, and the CoMP set can correspond to different in different first time periods. Collection of resources. The first central controller may determine, according to a jump pattern that includes the CI D corresponding to the resource set in different first time periods, that the CID of the CoMP set corresponds to a different first time period. A collection of resources, and obtaining configuration information of the collection of resources. That is, the resource set corresponding to the CoMP set can be jumped in different first time periods. Because the first resources in the resource set are orthogonal to each other, it can be ensured that a CoMP set is orthogonal to each other in the corresponding resource set at any time when the corresponding resource set jumps.

For example, the first time period may be one or more subframes, and determining the CI D of the CoM P set according to the jump pattern and the first time period may also be a jump according to the corresponding resource set in the corresponding first time period. The number of the pattern and the subframe determines that the CID of the CoMP set corresponds in the corresponding subframe. Collection of resources.

 The jump pattern includes a predefined jump pattern, and/or a jump pattern that is configured by the core network and notified to the first central controller. Specifically, the jump pattern may be determined by a jump sequence consisting of a resource set number (including a sequence of resource set numbers) and a jump pattern initialization parameter, where the jump pattern initialization parameter may be the starting resource set number or jump The offset value of the resource collection number. The offset value of the resource set number at the time of the jump may be determined by the CID and the correspondence between the CID and the offset value. The jump pattern initialization parameter, that is, the starting resource set number or the offset value of the resource set number at the time of the jump, may also be determined by the CID or not bound to the CID and determined by the dedicated jump pattern initialization parameter.

 Optionally, the first central controller may determine a jump pattern according to a CID of the CoMP set or according to a CID and a jump pattern initialization parameter of the CoMP set; and determining, by the resource set corresponding to the CoMP set, the resource set according to the jump pattern initialization parameter. When the jump is made, the configuration information of the resource set may further include a jump pattern initialization parameter. Or,

 The first central controller may further determine, according to the CID, a relationship between the CID and a jump sequence consisting of the resource set number, a jump sequence consisting of the resource set number, according to the jump sequence and the resource at the time of the jump. The offset value of the set number determines the jump pattern; or

 The first central controller may further determine, according to the CID, an offset value of the resource set number at the time of the jump according to the relationship between the CID and the offset value of the resource set number at the time of the jump, according to the jump composed of the resource set number. The sequence and the offset value determine the jump pattern.

 Correspondingly, the configuration information of the resource set may further include: a jump sequence composed of the resource set number and an offset value of the resource set number at the time of the jump, or a jump pattern.

Specifically: when the resource set corresponding to the CoMP set jumps in different first time periods, the jump pattern may be determined according to the CID of the CoMP set, so that each CID corresponds to a certain jump pattern. Each jump pattern may have a certain first time period or determine a set of resources to jump to according to a historical resource set in a predefined or dynamic manner. For example, when CID=1, the jump pattern sequence number corresponding to the jump pattern can be 1, 2, 3, 4, 5, so that the CoMP set with CID 1 is used in the first first time period in order. The resource set corresponding to number 1 (that is, the first resource set of the jump pattern), after the jump, the resource set corresponding to number 2 (ie, the second resource set of the jump pattern) is used, and the number 3 is used when jumping. The corresponding collection of resources, and so on, continue to loop. In addition, you can also determine a starting resource set number when determining the transition, for example: Determining the starting resource set number of the CoMP set is 3, then when CID=1, the jump pattern is 1, 2, 3, 4, 5, so that the CoMP set with CID 1 is in the first first time period in order. The resource set corresponding to the number 3 is used internally, and the resource set corresponding to the number 4 is used after the jump, and the resource set corresponding to the number 5 is used when the jump occurs, and so on, and the loop is continuously performed. Optionally, the starting resource set number may be determined according to the CID. For example, when CID=1, the starting resource set number is 3, and when CID=2, the starting resource set number is 5. The above determined relationship may be pre-defined or notified by the core network.

 Specifically, the determining of the jump pattern may be jointly determined according to the jump sequence consisting of the resource set number corresponding to the CID (ie, the resource set number) and the offset value of the resource set number at the time of the jump, for example, according to the jump pattern sequence. The jump sequence is 1, 2, 3, 4, 5, and the offset value of the resource set number at the time of the jump is 3, then the jump sequence corresponding to the jump pattern at the jump is 1 + 3, 2+3, 3+3, 4+3, 5+3, which is 4, 5, 6, 7, 8. If the resource set number exceeds the maximum resource set number G after using the offset value of the resource set number at the time of the jump, the resource set number obtained by the offset of the resource set number after the offset G is used as the resource set number used after the jump. . The determination of the jump pattern may also be determined according to the offset value of the resource set number at the time of the jump and the jump sequence (ie, the resource set number) composed of the resource set number corresponding to the CID, and the manner of determining the jump pattern is similar, no longer Narration. The above determined relationship may be predefined or notified by the core network.

 The jump pattern can also be determined based on the jump pattern parameters, and for each CoMP set, the jump pattern parameters can be predefined or core network notified. The jump pattern parameter may include a jump pattern sequence, a starting resource set number, or an offset value of the resource set number at the time of the jump. The manner of determining the jump pattern using the jump pattern parameter may be the same as the manner of determining the jump pattern using the CID, that is, determining the jump pattern sequence and the starting resource set according to the values of the jump pattern parameter, such as 1, 2, and the like according to the above manner. The offset value of the resource collection number when numbering or jumping.

 The jump pattern may also be jointly determined according to the CID and the jump pattern parameter. At this time, the jump sequence may be determined according to the CID, and the starting resource set number or the offset value of the resource set number at the time of the jump may be determined according to the jump pattern parameter; or Determining a jump sequence according to the jump pattern parameter, determining an initial resource set number or an offset value of the resource set number at the time of the jump according to the CID; or jointly determining the jump sequence and the starting resource set according to the CID and the jump pattern parameter The offset value of the resource collection number when numbering or jumping.

Optionally, when a resource set corresponding to a CoMP set is hopped, the first central controller may determine a jump of the resource set, and the number of the first resource in the resource set after the jump becomes X=N (D +D_init)+X_sub, where N is the resource collection size and D is determined according to the jump pattern sequence The resource set number corresponding to the jump time, DJnit is the jump initialization parameter, that is, the offset value of the resource set number at the time of the jump, X_sub is the number of the first resource in the resource set or X_sub can be the first resource before the jump Numbering. According to the difference of the jump pattern design, if the first resource number obtained according to X = N(D+D_init)+X_sub may exceed the maximum number of the first resource, the first resource number in the resource set after the jump may also be X = [N (D+D_init)+X_sub] mod X_max, where X_max is the maximum number of first resources. It may also be that if D+D_init is greater than the maximum resource set number G, the first resource number in the resource set after the jump is X=N [(D+D_init) mod G]+X_sub.

 Optionally, the configuration information of the first resource sent by the first central controller to the user equipment may further include: a jump parameter of the first resource; when determining the configuration information of the at least one first resource, the user equipment may be according to the first The jump parameter of the resource determines configuration information of at least one first resource in a different first time period. The jump parameter herein may correspond to a first resource jump pattern, where the first resource jump pattern includes a correspondence between different first time periods and the first resource.

 Optionally, the CID of the CoMP set may also correspond to different resource sets in different first frequency cycles, and the resource allocation method is similar to the foregoing method, and details are not described herein.

 It should be noted that the determining method of the correspondence between the CoMP set and the first resource set and the determining method of the first resource set jump corresponding to the CoMP set may be used independently or in combination. Since the CID identifier of the CoMP set can correspond to different resource sets in different first time periods, the flexibility of allocating resource sets for one CoMP set is increased, and the probability of the first resource overlap used between the CoMP sets is further reduced. FIG. 3 is a flowchart of another embodiment of a resource allocation method according to the present invention. As shown in FIG. 3, the method includes:

 The central controller acquires, according to the physical cell identifier PCID of the physical cell, configuration information of the non-zero power channel state information reference signal NZP CSI-RS set corresponding to the PCID, where

The NZP CSI-RS set includes at least one NZP CS Bu RS.

 The central controller sends configuration information of the at least one NZP CSI-RS in the NZP CSI-RS set to the user equipment, so that the user equipment determines the NZP CSI according to the configuration information of the NZP CSI-RS. RS, and performs channel measurement according to the NZP CSI-RS.

In the embodiment of the present invention, each physical cell corresponds to one physical cell identifier (Physical Cell) Indicator, PCID).

 In the embodiment of the present invention, each PCID corresponds to one NZP CSI-RS set, and the NZP CSI-RS set may include at least one NZP CSI-RS, so that the NZP CSI-RS corresponding to each physical cell can be coordinated, and the distance is reduced. The probability that the nearest physical cell uses the same NZP CSI-RS.

 The central controller may determine the PCID of the corresponding physical cell, and may further obtain configuration information of the corresponding NZP CSI-RS set according to the PCID.

 The central controller may send configuration information of at least one NZP CSI-RS to the user equipment through the serving cell or the serving base station of the user equipment, or the central controller directly sends configuration information of the at least one NZP CSI-RS to the user equipment. The serving cell of the user equipment may be a cell that provides a data transmission service to the user equipment to the user equipment or a cell that sends control information to the user equipment. The serving cell of the user equipment may or may not be a cell in the CoMP set that provides the user with data transmission services.

 In the embodiment of the present invention, the central controller may be a station or other network node, or the central controller may be a unit or module in the base station or other network nodes.

 As a possible implementation, a PRB pair has a plurality of patterns of NZP CSI-RSs, according to which the resource sets can be divided according to the pattern number of the NZP CSI-RS. In the division mode of the NZP CSI-RS set, each NZP CSI-RS set has the same subframe configuration, and the subframe configuration includes: a subframe period and a subframe in which the NZP CSI-RS set is located in the subframe period. Offset position. For example, if the subframe period is 5, the subframe where the NZP CSI-RS set is located may have an offset position of 0-4 in the period.

 In the implementation scenario where the NZP CSI-RS set can be divided according to the pattern number of the NZP CSI-RS, the configuration information of the NZP CSI-RS set may be: the pattern number of at least one NZP CSI-RS included in the NZP CSI-RS set. And subframe configuration information of the NZP CSI-RS set.

 After obtaining the configuration information of the corresponding NZP CSI-RS set according to the PCID of the physical cell, the central controller may send configuration information of at least one NZP CSI-RS in the corresponding NZP CSI-RS set to the UE.

It can be understood that the configuration information of the NZP CSI-RS set may include: a pattern number of at least one NZP CSI-RS included in the NZP CSI-RS set and subframe configuration information of the NZP CSI-RS set. Therefore, at least one of the central controller sends to the user equipment The configuration information of the NZP CSI-RS may be: a pattern number of the at least one NZP CSI-RS and subframe configuration information of the at least one NZP CSI-RS, thereby enabling the user equipment to configure information according to the at least one NZP CSI-RS Determining the at least one NZP CSI-RS and performing channel measurement according to the NZP CSI-RS.

 Optionally, the mapping between the pattern number of the NZP CSI-RS and the PCID of the corresponding physical cell may be: X mod 1 = PCID mod K, where X is the pattern number of the NZP CSI-RS resource, and the PCID is the PCID of the physical cell. , K is the maximum number of patterns of NZP CSI-RS. It should be noted that X here is the number of the pattern of available NZP CSI-RS resources, numbered from 0 or numbered from 1, such as NZP CSI-RS pattern number available in some systems from 20 (using normal cyclic prefix) Time) or 16 (when the extended cyclic prefix is used), but in the embodiment of the present invention, the number of X still starts from 0. For example, if the NZP CSI-RS pattern number in the system is 20, the X is 0, and the NZP CSI in the system. -RS pattern number 21 corresponds to X being 1, and so on.

 In this implementation scenario, the configuration information of the NZP CSI-RS sent by the central controller to the user equipment by the serving cell of the user equipment may include: (PCID mod K ) information and subframe configuration information of the NZP CSI-RS, NZP CSI- The subframe configuration information of the RS includes the subframe period and the offset position of the subframe in which the NZP CS is located in the period, so that the UE can determine according to the PCID, the (PCID mod K ) information, and the subframe configuration information of the NZP CSI-RS. NZP CSI-RS.

 As another possible implementation, all available or used NZP CSI-RSs can also be numbered, in this implementation scenario. The configuration information of the NZP CSI-RS set may be: a number of at least one NZP CSI-RS included in the NZP CSI-RS set. Correspondingly, the configuration information of the at least one NZP CSI-RS sent by the central controller to the user equipment by the serving cell of the user equipment may be: a number of the at least one NZP CSI-RS, so that the user equipment can be based on the at least one NZP CSI The number of the RS determines the configuration information of the at least one NZP CSI-RS, including the subframe configuration information.

 Specifically, the NZP CSI-RS set may also be divided into sub-collections, and NZPs in each sub-set

The subframe configuration of the CSI-RS can be different.

Specifically, the PCID of each physical cell may also correspond to different NZP CSI-RS sets in different first time periods, and the central controller may correspond to the NZP CSI-RS set according to the included PCID in different first time periods. The jump pattern of the relationship determines the corresponding NZP CSI-RS set of the PCID of the physical cell in different first time periods, and acquires the NZP CSI-RS set Configuration information. The NZP CSI-RS set hopping mode corresponding to the PCID of each physical cell and the resource set corresponding to the CoMP set in a manner that the central controller determines different NZP CSI-RS set configuration information in a different first time period The manner of the hopping is similar to the manner in which the central controller determines the corresponding resource set in the different first time period. For details, refer to the related description in the foregoing embodiment, and details are not described herein.

 On the basis of the foregoing embodiment, the central controller may also send the PCID of the physical cell to other central controllers or adjacent central controllers that are closer, for example, may be sent through a core network interface, for example, an X2 interface. The PCID of the physical cell, so that the NZP CSI-RS can be coordinated with the central controller or the adjacent central controller that is closer, so that the NZP CSI-RS sets do not coincide.

The PCID acquires configuration information of the corresponding NZP CSI-RS set, and sends configuration information of at least one NZP CSI-RS in the corresponding NZP CSI-RS set to the user equipment, so that the user equipment is based on the NZP CSI-RS. The configuration information determines the NZP CSI-RS and performs channel measurement according to the NZP CSI-RS. The PCID identifiers used by the relatively close physical cells are different, and the NZP CSI-RSs used by the corresponding physical cells can be coordinated and not overlapped with each other, thereby reducing the complexity of the actual system resource allocation and realizing the allocation to the distance. The NZP CSI-RS of different physical cells can be easily avoided, ensuring accuracy according to the measurement of the NZP CSI-RS. 4 is a schematic structural diagram of an embodiment of a central controller according to the present invention.
