TECHNICAL FIELD
Embodiments of the present invention relate to the field of communications technologies, and in particular, to a measurement method, a base station, and a user equipment.
BACKGROUND
In a Long Term Evolution (LTE) system, a smallest unit of a resource is a resource element (RE). An RE is a symbol in a time domain and is a subcarrier in a frequency domain. A resource block (RB) is a smallest unit for resource scheduling. An RB is a timeslot in the time domain and is 12 contiguous subcarriers in the frequency domain.
A heterogeneous network refers to a network including nodes with different powers. These nodes may include a macro base station (macro evolved NodeB, hereinafter referred to as macro eNB), a micro cell (Pico Cell), a home evolved NodeB (HeNB), a relay, and the like. Compared with a homogeneous network (that is, a network including macro base stations having a same transmit power), when heterogeneous network technologies are used, because an additional new serving node is introduced, an effect of cell splitting can be achieved, thereby improving system performance. However, in the heterogeneous network, because a low-power serving node is introduced, an interference scenario is different from that in the homogeneous network. If working frequencies of an interfering cell and an interfered-with cell are the same, a time division multiplexing (TDM) solution and a frequency division multiplexing (FDM) solution may be used to solve a problem of interference on a data channel.
In the TDM solution, an interfering cell (for example, a macro cell) transmits signals of different power levels in different subframes. In this way, because a low transmit power is allocated to some subframes or no data is sent in some subframes, these subframes are referred to as almost blank subframes (ABS). Therefore, in these subframes, an interfered-with cell (for example, a Pico Cell) schedules a user equipment (UE) in these subframes, where the user equipment is easily affected by the interfering cell, so as to reduce interference from the interfering cell (for example, the macro cell) to the UE in these subframes, thereby solving a problem of strong interference to the interfered-with cell (for example, the Pico Cell).
Because an ABS is introduced, interference features in different subframes may differ greatly. If measured subframes are not distinguished, it may cause wrong scheduling by a base station (evolved NodeB, hereinafter referred to as eNB). Therefore, the prior art introduces two subframe sets CCSI,0, and CCSI,1, which are used to measure resource-restricted channel state information (CSI) and provide feedback. Specifically, subframes having a same interference feature are grouped into one set, and a network may configure UE to perform channel quality indication (CQI) measurement and reporting in each of the two subframe sets. In this way, the eNB can schedule the UE in a more targeted manner according to measurement results that are reported by the UE and acquired in different measurement sets. However, similarly, the foregoing two measurement sets correspond to a same node connected to the UE.
In the prior art, a multiple stream aggregation (MSA) scenario is introduced in an LTE system, that is, one UE may be connected to multiple stations at the same time and receives service data from the multiple stations. The UE in the MSA scenario has a feature of dual connectivity, that is, one UE may be connected to multiple stations at the same time. For example, one UE may be connected to a macro base station and a micro base station (Pico eNB, hereinafter referred to as PeNB), where the macro base station and the PeNB may have a same frequency or may have different frequencies. Coverage areas of PeNBs are small, and if a UE moves fast, the UE easily moves from a coverage area of one PeNB into a coverage area of another PeNB frequently, causing frequent handovers of the UE. Dual connectivity enables a UE to keep connected to a macro base station and a PeNB at the same time, where the macro base station provides the UE with a service for content related to mobility management and a real-time service, while the PeNB provides only a data service. In this way, dual connectivity can avoid frequent handovers.
In the MSA scenario, for a UE on an edge of a coverage area of a Pico, a macro cell may serve the UE in a specific subframe (for example, a non-ABS of the macro cell) of the macro cell, while the Pico Cell serves the UE in a specific subframe (for example, a subframe corresponding to an ABS of the macro cell) of the Pico Cell. In this case, CSI measurement performed by the UE on the macro cell and the Pico Cell needs to correspond to a resource that can serve the UE, so that reference can be made to corresponding channel state information to satisfy a requirement for proper scheduling.
That is, in the MSA scenario, at least two transmission points provide data transmission services for a UE, and each serving point serves the UE in only a specific radio resource set.
In the prior art, there may be two sets on a node, and after a UE is notified of a configuration condition of the two sets, the UE performs CSI measurement on each of the two sets and provides feedback, so that a base station can perform data scheduling for the UE on a suitable resource.
However, in the prior art, only in a case in which two restricted measurement sets are from a same transmission point and only two restricted CSI measurement sets are configured on a node, a UE can be notified of a restricted measurement resource, but in an MSA scenario, when one or more specific radio resource sets are configured on each transmission point for the UE, the UE cannot be notified of the foregoing configured specific radio resource set.

DESCRIPTION OF EMBODIMENTS
To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
FIG. 1 is a flowchart of a measurement method according to an embodiment of the present invention. As shown in FIG. 1, the measurement method may include:
Step 101: A base station sends signaling to a user equipment, where the signaling carries node indication information, where the node indication information is used to indicate nodes corresponding to channel state information measurement sets configured by the base station for the user equipment, so that the user equipment measures, according to the node indication information, the nodes corresponding to the channel state information measurement sets on a resource corresponding to the channel state information measurement sets configured by the base station for the user equipment.
Step 102: The base station receives a measurement result reported by the user equipment, and schedules the user equipment according to the measurement result.
In the foregoing embodiment, signaling sent by a base station to a user equipment carries node indication information, where the node indication information is used to indicate nodes corresponding to channel state information measurement sets configured by the base station for the user equipment. In this way, the user equipment can learn, according to the node indication information, the nodes corresponding to the channel state information measurement sets configured by the base station for the user equipment; then, the user equipment can measure the nodes corresponding to the channel state information measurement sets on a resource corresponding to the channel state information measurement sets configured by the base station for the user equipment and provide feedback, so that the base station can schedule the user equipment according to a measurement result of the user equipment.
In a specific implementation manner of the embodiment shown in FIG. 1 of the present invention, on the basis of restricted resource CSI measurement sets currently configured for the user equipment, node indication information may be added, where the node indication information is used to indicate nodes corresponding to the restricted resource CSI measurement sets. Specifically, in step 101 in the embodiment shown in FIG. 1 of the present invention, that the signaling carries node indication information, where the node indication information is used to indicate nodes corresponding to channel state information measurement sets configured by the base station for the user equipment may be that: a channel state information subframe pattern configuration parameter carried in the signaling includes at least two newly-added channel state information measurement subframe set indication fields, where values of the at least two channel state information measurement subframe set indication fields indicate the nodes corresponding to the channel state information measurement sets configured by the base station for the user equipment.
The channel state information subframe pattern configuration parameter field may be CSI-SubframePatternConfig-r12, and the channel state information measurement subframe set indication field may be a csi-MeasSubframeSetCellId-r12 field. Certainly, this is merely an example, and this embodiment of the present invention is not limited thereto. Specific representation forms of the channel state information subframe pattern configuration parameter and the channel state information measurement subframe set indication field are not limited in this embodiment of the present invention.
For example, a csi-MeasSubframeSet1CellId-r12 field and a csi-MeasSubframeSet2CellId-r12 field may be added to CSI-SubframePatternConfig-r12, where a value of the csi-MeasSubframeSet1CellId-r12 field indicates a node corresponding to csi-MeasSubframeSet1-r10, and a value of the csi-MeasSubframeSet2CellId-r12 field indicates a node corresponding to csi-MeasSubframeSet2-r10. Specific implementation may be as follows:

 }



}









In this case, if the user equipment works in an MSA state, the nodes corresponding to the channel state information measurement sets and indicated by the values of the at least two channel state information measurement subframe set indication fields are completely different or completely the same or partially the same. Specifically, FIG. 2 is a schematic diagram of a resource set of a serving node of a user equipment working in an MSA state according to an embodiment of the present invention. As can be seen from FIG. 2, the channel state information measurement sets configured by the base station for the user equipment include csi-MeasSubframeSet1-r10 and csi-MeasSubframeSet2-r10, where csi-MeasSubframeSet1-r10 is an odd-number subframe set on a TP1, and csi-MeasSubframeSet2-r10 is an even-number subframe set on a TP2. In this case, a csi-MeasSubframeSet1CellId-r12 field and a csi-MeasSubframeSet2CellId-r12 field may be added to CSI-SubframePatternConfig-r12, where a value of the csi-MeasSubframeSet1CellId-r12 field is used to indicate that a node corresponding to csi-MeasSubframeSet1-r10 is the TP1, and a value of the csi-MeasSubframeSet2CellId-r12 field is used to indicate that a node corresponding to csi-MeasSubframeSet2-r10 is the TP2.
Certainly, FIG. 2 shows merely an embodiment of a channel state information measurement set configured by the base station for the user equipment. In FIG. 2, the base station configures only two channel state information measurement sets for the user equipment, and the two channel state information measurement sets are on different nodes. This embodiment of the present invention is not limited thereto; and the base station may configure at least two channel state information measurement sets for the user equipment, and nodes corresponding to the at least two channel state information measurement sets are completely different or completely the same or partially the same.
That nodes corresponding to the at least two channel state information measurement sets are completely different or completely the same or partially the same includes the following cases:
(1) the nodes corresponding to the at least two channel state information measurement sets are completely different;
(2) the nodes corresponding to the at least two channel state information measurement sets are a same node; and
(3) some of the at least two channel state information measurement sets correspond to a same node, and the other sets correspond to at least one node.
For example, the channel state information measurement sets configured by the base station for the user equipment may include csi-MeasSubframeSet1-r10, csi-MeasSubframeSet2-r10, csi-MeasSubframeSet3-r10, and csi-MeasSubframeSet4-r10, where csi-MeasSubframeSet1-r10 and csi-MeasSubframeSet2-r10 are subframe sets on a TP1, csi-MeasSubframeSet3-r10 is a subframe set on a TP2, and csi-MeasSubframeSet4-r10 is a subframe set on a TP3. In this case, a csi-MeasSubframeSet1CellId-r12 field, a csi-MeasSubframeSet2CellId-r12 field, a csi-MeasSubframeSet3CellId-r12 field, and a csi-MeasSubframeSet4CellId-r12 field may be added to CSI-SubframePatternConfig-r12, where a value of the csi-MeasSubframeSet1CellId-r12 field is used to indicate that a node corresponding to csi-MeasSubframeSet1-r10 is the TP1, a value of the csi-MeasSubframeSet2CellId-r12 field is used to indicate that a node corresponding to csi-MeasSubframeSet2-r10 is the TP1, a value of the csi-MeasSubframeSet3CellId-r12 field is used to indicate that a node corresponding to csi-MeasSubframeSet3-r10 is the TP2, and a value of the csi-MeasSubframeSet4CellId-r12 field is used to indicate that a node corresponding to csi-MeasSubframeSet4-r10 is the TP3.
If the user equipment works in a non-MSA state, the nodes corresponding to the channel state information measurement sets and indicated by the values of the at least two channel state information measurement subframe set indication fields are a same node. Specifically, FIG. 3 is a schematic diagram of a resource set of a serving node of a user equipment working in a non-MSA state according to an embodiment of the present invention. As can be seen from FIG. 3, the channel state information measurement sets configured by the base station for the user equipment include csi-MeasSubframeSet1-r10 and csi-MeasSubframeSet2-r10, where csi-MeasSubframeSet1-r10 is an odd-number subframe set on a TP2, and csi-MeasSubframeSet2-r10 is an even-number subframe set on the TP2. In this case, a csi-MeasSubframeSet1CellId-r12 field and a csi-MeasSubframeSet2CellId-r12 field may be added to CSI-SubframePatternConfig-r12, where a value of the csi-MeasSubframeSet1CellId-r12 field is used to indicate that a node corresponding to csi-MeasSubframeSet1-r10 is the TP2, and a value of the csi-MeasSubframeSet2CellId-r12 field is used to indicate that a node corresponding to csi-MeasSubframeSet2-r10 is the TP2.
In another specific implementation manner of the embodiment shown in FIG. 1 of the present invention, further, in step 101 in the embodiment shown in FIG. 1 of the present invention, the signaling may further carry measurement set indication information, where the measurement set indication information is used to indicate the channel state information measurement sets configured by the base station on the nodes for the user equipment.
Specifically, in step 101 in the embodiment shown in FIG. 1 of the present invention, that the signaling carries node indication information, where the node indication information is used to indicate nodes corresponding to channel state information measurement sets configured by the base station for the user equipment may be that: a configuration parameter carried in the signaling includes a newly-added channel state information measurement subframe indication field, where different values of the channel state information measurement subframe indication field indicate the nodes corresponding to the channel state information measurement sets configured by the base station for the user equipment; and

The channel state information measurement subframe indication field may be a csi-MeasSubframeCellId-r12 field, and the channel state information subframe pattern configuration parameter field may be a csi-SubframePatternConfig-r12 field. Certainly, this is merely an example, and this embodiment of the present invention is not limited thereto. Specific representation forms of the channel state information measurement subframe indication field and the channel state information subframe pattern configuration parameter field are not limited in this embodiment of the present invention.
For example, a csi-MeasSubframeCellId-r12 field may be newly added to CQI-ReportConfig-r12, where values of the csi-MeasSubframeCellId-r12 field indicate the nodes corresponding to the channel state information measurement sets configured by the base station for the user equipment; and a csi-SubframePatternConfig-r12 field is newly added to CQI-ReportConfig-r12, where values of the csi-SubframePatternConfig-r12 field indicate at least one channel state information measurement set configured by the base station on the nodes for the user equipment.

If the user equipment works in a non-MSA state, the base station sets the channel state information measurement subframe indication field to a fifth value, so as to indicate a node corresponding to channel state information measurement sets configured by the base station for the user equipment; and sets the channel state information subframe pattern configuration parameter field to a sixth value and a seventh value, so as to indicate that the two channel state information measurement sets configured by the base station on the node for the user equipment are a set indicated by the sixth value and a set indicated by the seventh value.
That the base station configures two channel state information measurement sets on a node for the user equipment in a non-MSA state is merely used as an example for description in the foregoing, and this embodiment of the present invention is not limited thereto. If the user equipment works in a non-MSA state, the base station may configure at least one channel state information measurement set on a node for the user equipment, and different values of the channel state information subframe pattern configuration parameter field can indicate the at least one channel state information measurement set configured by the base station on the node for the user equipment.

In this embodiment of the present invention, the channel state information measurement sets configured by the base station for the user equipment are orthogonal.
FIG. 4 is a flowchart of a measurement method according to another embodiment of the present invention. As shown in FIG. 4, the measurement method may include:
Step 401: A user equipment receives signaling sent by a base station, where the signaling carries node indication information, where the node indication information is used to indicate nodes corresponding to channel state information measurement sets configured by the base station for the user equipment.
Step 402: The user equipment measures, according to the node indication information, the nodes corresponding to the channel state information measurement sets on a resource corresponding to the channel state information measurement sets configured by the base station for the user equipment.
Step 403: The user equipment reports a measurement result to the base station, so that the base station schedules the user equipment according to the measurement result.

The channel state information subframe pattern configuration parameter field may be CSI-SubframePatternConfig-r12, and the channel state information measurement subframe set indication field may be a csi-MeasSubframeSetCellId-r12 field. Certainly, this is merely an example, and this embodiment of the present invention is not limited thereto. Specific representation forms of the channel state information subframe pattern configuration parameter and the channel state information measurement subframe set indication field are not limited in this embodiment of the present invention.
The channel state information subframe pattern configuration parameter field may be CSI-SubframePatternConfig-r12, and the channel state information measurement subframe set indication field may be a csi-MeasSubframeSetCellId-r12 field. Certainly, this is merely an example, and this embodiment of the present invention is not limited thereto. Specific representation forms of the channel state information subframe pattern configuration parameter and the channel state information measurement subframe set indication field are not limited in this embodiment of the present invention.
In this case, if the user equipment works in an MSA state, the nodes corresponding to the channel state information measurement sets and indicated by the values of the at least two channel state information measurement subframe set indication fields are completely different or completely the same or partially the same; or if the user equipment works in a non-MSA state, the nodes corresponding to the channel state information measurement sets and indicated by the values of the at least two channel state information measurement subframe set indication fields are a same node.
In another implementation manner of this embodiment, in step 401, the signaling received by the user equipment further carries measurement set indication information, where the measurement set indication information is used to indicate the channel state information measurement sets configured by the base station on the nodes for the user equipment.
Specifically, that the signaling carries node indication information, where the node indication information is used to indicate nodes corresponding to channel state information measurement sets configured by the base station for the user equipment may be that: a configuration parameter carried in the signaling includes a newly-added channel state information measurement subframe indication field, where different values of the channel state information measurement subframe indication field indicate the nodes corresponding to the channel state information measurement sets configured by the base station for the user equipment; and
that the signaling further carries measurement set indication information, where the measurement set indication information is used to indicate the channel state information measurement sets configured by the base station on the nodes for the user equipment may be that: the configuration parameter carried in the signaling includes a newly-added channel state information subframe pattern configuration parameter field, where different values of the channel state information subframe pattern configuration parameter field indicate at least one channel state information measurement set configured by the base station on the nodes for the user equipment.
In this implementation manner, if the user equipment works in an MSA state, when a value of the channel state information measurement subframe indication field is a first value, it indicates that a first channel state information measurement set configured by the base station for the user equipment corresponds to a first node; and when a value of the channel state information subframe pattern configuration parameter field is a second value, it indicates that the first channel state information measurement set configured by the base station on the first node for the user equipment is a set indicated by the second value; and/or
when a value of the channel state information measurement subframe indication field is a third value, it indicates that a second channel state information measurement set configured by the base station for the user equipment corresponds to a second node; and when a value of the channel state information subframe pattern configuration parameter field is a fourth value, it indicates that the second channel state information measurement set configured by the base station on the second node for the user equipment is a set indicated by the fourth value.
The foregoing is merely an example, and this embodiment of the present invention is not limited thereto. If the user equipment works in an MSA state, the base station may configure at least two channel state information measurement sets for the user equipment, and in this case, a channel state information measurement subframe indication field may be newly added to a configuration parameter carried in the signaling, where different values of the channel state information measurement subframe indication field indicate nodes corresponding to the at least two channel state information measurement sets configured by the base station for the user equipment. It should be noted that the nodes corresponding to the at least two channel state information measurement sets configured by the base station for the user equipment are completely different or completely the same or partially the same, which includes the following cases:
(1) the nodes corresponding to the at least two channel state information measurement sets are completely different;
(2) the nodes corresponding to the at least two channel state information measurement sets are a same node; and
(3) some of the at least two channel state information measurement sets correspond to a same node, and the other sets correspond to at least one node.
If the user equipment works in a non-MSA state, when a value of the channel state information measurement subframe indication field is a fifth value, it indicates a node corresponding to channel state information measurement sets configured by the base station for the user equipment; and when values of the channel state information subframe pattern configuration parameter field are a sixth value and a seventh value, it indicates that the at least two channel state information measurement sets configured by the base station on the node for the user equipment are a set indicated by the sixth value and a set indicated by the seventh value.
That the base station configures two channel state information measurement sets on a node for the user equipment in a non-MSA state is merely used as an example for description in the foregoing, and this embodiment of the present invention is not limited thereto. If the user equipment works in a non-MSA state, the base station may configure at least one channel state information measurement set on a node for the user equipment, and different values of the channel state information subframe pattern configuration parameter field indicate the at least one channel state information measurement set configured by the base station on the node for the user equipment.
For example, the base station may set the channel state information measurement subframe indication field to a fifth value, so as to indicate a node corresponding to channel state information measurement sets configured by the base station for the user equipment; and set the channel state information subframe pattern configuration parameter field to a sixth value, a seventh value, and an eighth value, so as to indicate that the channel state information measurement sets configured by the base station on the node for the user equipment are a set indicated by the sixth value, a set indicated by the seventh value, and a set indicated by the eighth value.
In the foregoing embodiment, signaling sent by a base station to a user equipment carries node indication information, where the node indication information is used to indicate nodes corresponding to channel state information measurement sets configured by the base station for the user equipment. In this way, the user equipment can learn, according to the node indication information, the nodes corresponding to the channel state information measurement sets configured by the base station for the user equipment; then, the user equipment can measure the nodes corresponding to the channel state information measurement sets on a resource corresponding to the channel state information measurement sets configured by the base station for the user equipment and provide feedback, so that the base station can schedule the user equipment according to a measurement result of the user equipment.
According to the measurement method provided in the embodiments of the present invention, the node indication information is added, to indicate the nodes corresponding to the channel state information measurement sets configured by the base station for the user equipment, so that a same message can be used for resource configuration for restricted CSI measurement sets in an MSA scenario and a non-MSA scenario, and therefore, measurement resource configuration is flexible.
