METHOD OF PROCESSING CHANNEL AND APPLIANCE STATUS INFORMATION [001] This application claims priority from Chinese Patent Application No. 201710314139.7, filed with the National Intellectual Property Administration of China on May 5, 2017 and entitled CHANNEL STATE INFORMATION PROCESSING METHOD AND APPARATUS THEREOF, which is incorporated herein by reference in its entirety.
TECHNICAL FIELD [002] The present invention relates to the communications field and, in particular, to a method of processing channel status information and an apparatus thereof.
BACKGROUND [003] In a multi-point coordinated multi-station base transmission scenario, a network side needs to configure a plurality of channels and interference measurement features, and a terminal device side needs to measure and feed back channel state information ( Channel State Information, CSI) in one or more cases of interference, so that the network side appropriately determines a coordinated multi-point multi-base transmission transmission scheme, corresponding adaptive link configuration, and a scaling policy based on a plurality of parts of CSI.
[004] Figure 1 is a schematic diagram of a multipoint transmission scenario coordinated by three base stations. A Transmission Reception Point (TRP) 1, a TRP 2, and a TRP 3 are transmission base stations coordinated in a coordination set, and a TRP 4 is an interference base station located outside the
Petition 870190075528, of 08/06/2019, p. 7/84
2/70 coordination set. For TRP 1, the following possible combinations of interference exist:
an interference 1 measurement hypothesis: interference from TRP 2 in the coordination set and interference from TRP 4 outside the coordination set;
an interference measurement hypothesis 2: interference from TRP 3 in the coordination set and interference from TRP 4 outside the coordination set;
an interference measurement hypothesis 3: interference from TRP 2 and TRP 3 in the coordination set and interference from TRP 4 outside the coordination set; and an interference measurement hypothesis 4: interference from TRP 4 outside the coordination set.
[005] The terminal device needs to measure and feedback CSI in one or more of the interference measurement assumptions above, so that the network side determines the multi-base coordinated transmission scheme, the corresponding adaptive link configuration, and programming policy.
[006] In Long Term Evolution (LTE), the network side sets up a CSI process and the terminal device performs measurements and reports based on the configured CSI process. A plurality of CSI processes need to be set up to measure the CSI in different cases of interference. A CSI process corresponds to an interference measurement hypothesis. When a quantity
Petition 870190075528, of 08/06/2019, p. 8/84
3/70 coordinated base stations are increased, a number of interference measurement possibilities are also increased. Consequently, the number of CSI processes required for measurement and reporting is increased, and a system is not scalable. A CSI process includes a non-zero power channel state information reference reference signal resource (NZP CSI-RS) used for channel measurement and a zero power channel state information reference (Zero Power Channel State Information-Reference Signal, ZP CSI-RS) used for interference measurement, and when the number of interference measurement hypotheses is increased, it is necessary to configure more ZP CSI-RS. Consequently, a large amount of downlink transmission resources are occupied.

DESCRIPTION OF THE MODALITIES [0039] The modalities of the present invention can be applied to a wireless communication system. The wireless communications system generally includes a cell, each cell incorporates a base station (Base Station, BS), and the base station provides a communication service for a plurality of terminal devices. The base station includes a base band unit (Baseband Unit, BBU) and a remote radio unit (Remote Radio Unit, RRU). BBU and RRU can be arranged in different locations. For example, the RRU is remote and is arranged close to a wide region of heavy traffic, and the BBU is arranged in a central equipment room. BBU and RRU can alternatively be placed in the same equipment room. BBU and RRU can be alternatively different components in the same

19/70 structure.
[0040] It should be noted that the wireless communications system mentioned in the modalities of the present invention includes, but is not limited to, a narrowband Internet of Things (NB-IoT) system, a Global System for Mobile Communications (Global System for Mobile Communications, GSM), enhanced data rates for the GSM evolution system (Enhanced Data rate for GSM Evolution, EDGE), a Multiple Access system by Broadband Code Division ( Wideband Code Division Multiple Access, WCDMA), a Code Division Multiple Access 2000 system (Code Division Multiple Access2000, CDMA 2000), a Time Division Synchronization Code Division Multiple Access System Access, TD-SCDMA), a Long Term Evolution System,
LTE), a NR system it is a future system communications furniture. [0041] THE station base in the modalities gives gift invention is one device what is implanted in a network access
radio and that is configured to provide a wireless communication function for a terminal device. The base station can include a macro base station, a micro base station (also referred to as a small cell), a relay station, an access point, a TRP, and the like in various forms. In systems that use different radio access technologies, the names of a device that has a base station function can be different. For example, in an LTE system, the device is referred to as an evolved NodeB (evolved NodeB, eNB or eNodeB) and, in an
Petition 870190075528, of 08/06/2019, p. 25/84
20/70
3rd generation (3rd Generation, 3G), the device is referred to as NodeB (Node B NB). To facilitate description, in all embodiments of the present invention, all prior devices that provide a wireless communication function for the terminal device are collectively referred to as a network device.
[0042] The terminal device in the embodiments of the present invention can include various portable devices, devices in vehicles, wearable devices, or computing devices that have a wireless communication function, or other processing devices connected to a wireless modem. The terminal device can also be referred to as a mobile station (mobile station, MS) or a terminal (terminal) and can also include a subscriber unit (subscriber unit), a cell phone (cellular phone), a smartphone (smartphone), a wireless data card, a personal digital assistant (PDA), a tablet, a wireless modem (modem), a portable device (handset), a laptop (laptop computer), a communication terminal of the type machine type communication, MTC) and the like. For ease of description, in all embodiments of the present invention, the devices mentioned above are collectively referred to as the terminal device.
[0043] The modalities of the present invention can be applied to a schematic diagram of a three base station coordinated multipoint transmission scenario shown in Figure 1. A TRP 1, TRP 2 and TRP 3 are coordinated transmission base stations in one coordination set, and a TRP 4 is an interference base station
Petition 870190075528, of 08/06/2019, p. 26/84
21/70 located outside the coordination set. For a TRP in the coordination set, there is at least one interference caused by other TRPs in the coordination set for the TRP and interference caused by the TRP outside the coordination set for the TRP. For example, for TRP 1, there are four possible hypotheses for measuring interference. A first interference measurement hypothesis is interference from TRP 2 in the coordination set and TRP 4 interference outside the coordination set, a second interference measurement hypothesis is interference from TRP 3 in the coordination set and interference from TRP 4 outside the coordination set, a third interference measurement hypothesis is interference from TRP 2 and TRP in the coordination set and interference from TRP outside the coordination set, and a fourth hypothesis Interference measurement is interference from TRP 4 outside the coordination set. For a case where there is a plurality of interference measurement assumptions, the terminal device needs to measure and feedback CSI on one or more of the interference measurement assumptions, so that a network side determines a multi-coordinate transmission scheme base station, corresponding adaptive link configuration, and a programming policy.
[0044] In LTE, the network side configures a CSI process for an interference measurement hypothesis. When an amount of coordinated base stations is increased, an amount of interference measurement hypotheses is also increased. Consequently, the number of CSI processes that need to be configured is increased and a system
Petition 870190075528, of 08/06/2019, p. 27/84
22/70 is not scalable. A CSI process includes a non-zero energy channel status reference signal feature, NZP CSI-RS, used for channel measurement and a ZP CSI-RS feature used for interference measurement. When the number of interference measurement hypotheses increases, more features of ZP CSI-RS need to be configured. Consequently, a large amount of downlink transmission resources are occupied.
[0045] With this in mind, the modalities of the present invention provide a method of processing channel state information and an apparatus thereof, so that when an amount of coordinated base stations is increased, the system can be scalable and a case where excessive downlink transmission resources are busy can be avoided.
[0046] A new Third Generation Partnership (3GPP) project defines a new CSI reporting and measurement architecture, including CSI reporting setting information (CSI Reporting Setting), resource setting information (Resource Setting) and information Measurement Setting. For a terminal device, a metering configuration is configured, and the metering configuration includes at least one CSI reporting configuration, at least one resource configuration and at least one association (link) relationship. A link indicates an association between a CSI reporting configuration and a resource configuration, and indicates that the resource configuration is used for channel or interference measurement.
[0047] Figure 2 is an example diagram of a measurement configuration indication scheme based on
Petition 870190075528, of 08/06/2019, p. 28/84
23/70 CSI measurement and reporting architecture. A CSI 0 reporting configuration is used as an example and the CSI 0 reporting configuration is connected to a resource configuration 0 and a resource configuration 1 using two links. The resource configuration 0 includes K channel state information-interference measurement (CSIIM) capabilities used for interference measurement. Resource configuration 1 includes a channel state informationreference signal, CSI-RS, used for channel measurement. In the scheme, I CSI-IM resources are selected from the K CSI-IM resources and used as an interference measurement hypothesis. When the CSI is calculated, the channel information measured using the CSI-RS resource in resource configuration 1 is used as a signal part and the channel information measured using a CSI-IM resource in resource configuration 0 is used as a part of interference. If the measurement needs to be performed based on a plurality of interference measurement assumptions, the network side needs to indicate the plurality of interference measurement assumptions, needs to perform the indication several times and indicate several CSI-IM features each time . Consequently, there is a large number of referral overheads.
[0048] Figure 3 is an example diagram of an existing measurement and reporting method. The network side configures three resource settings. A resource configuration 0 corresponds to channel measurement, a resource configuration 1 corresponds to interference measurement 1 and a configuration
Petition 870190075528, of 08/06/2019, p. 29/84
24/70 of resource 2 corresponds to interference measurement 2. In Figure 3, there are four interference measurement hypotheses (Hypotheses H1 to H4). The terminal device selects, according to one criterion, a CSI report
corresponding to one or more hypotheses in measurement in interference and information in recommendation gives hypothesis in interference measurement corresponding, and report O
CSI report and referral information. The interference measurement hypothesis indication information includes a sequence number for one or more resource configurations. For example, to report CSI reports corresponding to Hl and H3, sequence numbers 1 and 2 for resource configurations corresponding to Hl, and a sequence number 2 of a resource configuration corresponding to H3 must be reported. When a number of coordinated base stations is increased, a number of resource configurations are also increased, and a number of interference measurement hypotheses and a number of resource configurations included in each interference measurement hypothesis are also increased, leading to an increase in reporting overhead from the terminal device.
[0049] In view of the disadvantages that when the number of coordinated base stations is increased, the indication overheads generated when the network side indicates that the interference measurement hypotheses increase and the report overheads generated when a terminal side executes reports are increased, in the method of processing channel status information and the apparatus thereof that are provided in the modalities of the present invention, the

25/70 network can instruct the terminal side to selectively perform measurement and reporting, and measurement and reporting are performed based on a CSI-RS feature set, thereby reducing reporting overheads and reporting overheads.
[0050] The method of processing channel state information provided in the embodiments of the present invention is described in detail below with reference to Figure 4 to Figure 9.
[0051] Figure 4 is a schematic communication diagram of a method of processing channel state information according to an embodiment of the present invention. The description is provided from the perspective of interaction between a network device and a terminal device, and the method includes, but is not limited to, the following steps.
[0052] Step S201: A network device configures at least a part of the CSI report configuration information and resource configuration information corresponding to at least a part of the CSI report configuration information.
[0053] Specifically, the network device can configure at least a part of the CSI reporting setting information (CSI Reporting Setting) and resource setting information (Resource Setting) corresponding to at least a part of the report configuration information of CSI for any terminal device in the coverage of the device network. A portion of the CSI reporting configuration information corresponds to at least two pieces of
Petition 870190075528, of 08/06/2019, p. 31/84
26/70 feature. The resource configuration information corresponding to at least part of the CSI report configuration information is a set, and the set includes at least two parts of resource configuration information corresponding to each part of the CSI report configuration information . To be specific, the network device can configure at least two resource configuration information for each of at least a portion of the CSI reporting configuration information in an associated manner, in other words, each portion of the configuration information for CSI report corresponds to at least two pieces of resource configuration information. This embodiment of the present invention is described using an example in which there are two parts of resource configuration information, and a case of at least three parts of resource configuration information can be obtained by analogy.
[0054] One of the at least two pieces of resource configuration information corresponding to a portion of the configuration information of the CSI report is used for interference measurement, includes a CSI-RS resource set (CSI-RS Resource Set) , and specifically includes at least one CSI-RS feature set. One of at least two pieces of resource configuration information is used for channel metering, includes an NZP CSI-RS resource, and specifically includes at least one NZP CSI-RS resource. A CSI-RS resource set corresponds to at least one interference measurement hypothesis, and the CSI-RS resource set includes at least one NZP CSI resource
Petition 870190075528, of 08/06/2019, p. 32/84
27/70
RS and a ZP CSI-RS feature. For example, a CSI-RS feature set corresponds to an interference measurement hypothesis, and a CSI-RS # 1 feature set includes an NZP CSI-RS B feature and a ZP CSI-RS D feature. In this case, the CSI-RS # 1 feature set corresponds to an interference measurement hypothesis.
[0055] For example, a resource configuration 0 and a resource configuration 1 are configured for a CSI reporting configuration 0 in an associated manner. The resource setting 0 is used for channel measurement and includes at least one NZP CSI-RS resource. Feature 1 configuration is used for interference measurement and includes at least one CSI-RS feature set.
[0056] A CSI-RS resource set corresponds to at least one CSI report, and a CSI report includes a channel measurement result and an interference measurement result. When the resource configuration information used for channel measurement includes an NZP CSI-RS resource, a CSI-RS resource set corresponds to a CSI report. When the resource configuration information used for channel measurement includes at least two NZP CSI-RS resources, one CSIRS resource set corresponds to at least two CSI reports.
[0057] A portion of the CSI reporting configuration information corresponds to at least two pieces of resource configuration information, and the resource configuration information used for interference measurement corresponds to at least one CSI-RS resource set. , so that it can be learned by analogy that some of the CSI reporting configuration information corresponds
Petition 870190075528, of 08/06/2019, p. 33/84
28/70 to at least one CSI-RS resource set, and one can also learn by analogy that at least a portion of the CSI report configuration information corresponds to at least one CSI-RS resource set. In all embodiments of the present invention, it is assumed that an amount of all CSI-RS resource sets corresponding to at least part of the CSI reporting configuration information is M, in other words, at least part of the CSI report configuration information corresponds to M CSI-RS resource sets, where M is a positive integer, M> 1 and a specific value of M is not limited.
[0058] CSI report configuration information includes configuration information for a CSI report. The configuration information for the CSI report can be used to instruct the terminal device to report the contents of the CSI report. The content of the CSI report can include at least one of the parameters such as a channel quality indicator (CQI), a precoding matrix indicator (PMI), a ranking indication (rank indication, RI) and a channel state information-reference signal resource indicator indicator, CRI. The configuration information of the CSI report can further instruct the terminal device to report a time domain characteristic, a frequency domain characteristic, and the like.
[0059] The network device can configure indication indication information corresponding to at least one
Petition 870190075528, of 08/06/2019, p. 34/84
29/70 part of the CSI report configuration information, and a part of the CSI report configuration information corresponds to at least two pieces of association indication information (link). The membership indication information corresponding to at least a portion of the CSI report configuration information is a set, and the set includes at least two pieces of association indication information corresponding to each part of the CSI report configuration information . To be specific, the network device can configure at least two pieces of association indication information for each piece of CSI report configuration information. One of the at least two membership indication information indicates an identifier for the CSI reporting configuration information and an identifier for a portion of the resource configuration information, and indicates that the resource configuration information is used for channel measurement . One of the at least two association indication information indicates the identifier for the CSI reporting configuration information and an identifier for a portion of the resource configuration information, and indicates that the resource configuration information is used for interference measurement. This embodiment of the present invention is described using an example in which there are two pieces of association indication information, and a case of at least three pieces of association indication information can be obtained by analogy. For example, link 1 and link 2 are configured for the CSI 0 reporting configuration. Link 1 indicates that an
Petition 870190075528, of 08/06/2019, p. 35/84
30/70 CSI report is 0 and a resource configuration identifier is 0 and indicates that resource configuration 0 is used for channel measurement. Link 2 indicates that the CSI reporting configuration identifier is 0 and a resource configuration identifier is 1, and indicates that resource configuration 1 is used for interference measurement.
[0060] The network device can configure, in the radio resource control signaling (RRC), at least a part of the CSI report configuration information and the resource configuration information corresponding to at least one part of CSI report configuration information. The network device can configure, in the RRC signaling, at least a part of the CSI report configuration information, the resource configuration information corresponding to at least a part of the CSI report configuration information and the indication information of association corresponding to at least a portion of the CSI reporting configuration information.
[0061] Based on the schematic diagram of the scenario shown in Figure 1, referring to a table of examples of CSI-RS resource allocation that is based on Figure 1 and which is shown in Figure 5, a NZP CSI- RS (A) is allocated to a TRP 1, an NZP CSI-RS (B) resource is allocated to a TRP 2, an NZP CSI-RS (C) resource is allocated to a TRP 3, and a ZP resource CSI-RS (D) is allocated for TRP 1, TRP 2 and TRP 3. The NZP CSI-RS feature can be used for interference measurement or can be used for channel measurement. The ZP CSI-RS (D) feature can be used

32/70 [0063] It can be learned from the four CSI-RS resource sets that two CSI-RS resource sets can include the same NZP CSI-RS resource, can include the same ZP CSI-RS resource, or they can include the same NZP CSP-RS resource and the same ZP CSI-RS resource. In addition, it can be learned by analogy that the same CSI-RS resource can be shared among a plurality of CSI-RS resource sets, so that a disadvantage that a large amount of connection transmission resources can be overcome Downstream is busy and CSI processes cannot share a measurement resource and measurement result in LTE, thereby saving downlink transmission resources and increasing a degree of sharing of the measurement resource and the measurement result.
[00 64] Figure 7 is an example diagram of configuration according to an embodiment of the present invention. Based on the schematic diagram of the scenario shown in Figure 1, the network device configures the CSI reporting configuration 0, and configures resource configuration 0, resource configuration 1, link 1 (Link 1) and link 2 ( Link 2) for the CSI 0 reporting configuration in an associated manner. Link 1 indicates an association between CSI report configuration 0 and resource configuration 0 and indicates that resource configuration 0 is used for channel measurement. Link 2 indicates an association between CSI report configuration 0 and resource configuration 1, and indicates that resource configuration 1 is used for interference measurement. The resource configuration 0 includes the resource
Petition 870190075528, of 08/06/2019, p. 38/84
33/70 NZP CSI-RS (A), and resource configuration 1 includes the four CSI-RS resource sets.
[0065] Figure 8 is another example diagram of configuration according to an embodiment of the present invention. The network device configures CSI 0 reporting configuration and configures resource 0 configuration, resource 1 configuration, link 1 and link 2 for CSI 0 reporting configuration in an associated manner. Link 1 indicates an association between the CSI report configuration 0 and resource configuration 0 and indicates that resource configuration 0 is used for channel measurement. Link 2 indicates an association between the CSI 0 reporting configuration and resource 1 configuration, and indicates that resource 1 configuration is used for interference measurement. Resource configuration 0 includes the NZP CSI-RS resource (A) and the NZP CSI-RS resource (B), and resource configuration 1 includes the following three CSI-RS resource sets:
one set of resource in CSI-RS #1, including O resource in NZP CSI-RS (C) and the resource from ZP CSI -RS (D); one set of resource in CSI-RS #2, including O resource in NZP CSI-RS (A) and the resource from ZP CSI -RS (D); and one set of resource in CSI-RS # 3, including O resource in ZP CSI-RS (D).
[0066] It should be noted that Figure 7 and Figure 8 are described using a CSI report setup as an example, and a case of at least two CSI report settings can be obtained by analogy based on Figure 7 and Figure 8. Figure 7 uses an example in which resource configuration 0 includes only NZP resource
Petition 870190075528, of 08/06/2019, p. 39/84
34/70
CSI-RS (A), Figure 8 uses an example in which resource configuration 0 includes only two NZP CSI-RS resources, and a case in which the resource configuration information used for channel metering includes at least two NZP CSI-RS resources can be obtained through an extension based on Figure 8.
[0067] When the amount of NZP CSI-RS resources included in the resource configuration information used for channel measurement is greater than 1, the network device may configure a match between an NZP CSI-RS resource used for measurement of channel channel and a CSI-RS feature set used for interference measurement. For example, in Figure 8, the network device configures the following matches:
a match 1 between the NZP CSI-RS resource (A) and the CSI-RS resource set # 1;
a match 2 between the NZP CSI-RS resource (A) and the CSI-RS resource set # 3;
a match 3 between the NZP CSI-RS resource (B) and the CSI-RS resource set # 1;
a match 4 between the NZP CSI-RS resource (B) and the CSI-RS resource set # 2; and a match 5 between the NZP CSI-RS resource (B) and the CSI-RS resource set # 3.
[0068] Correspondences 1 to 5 are used to indicate correspondences between the resource configuration information 0 used for channel measurement and the resource configuration information 1 used for interference measurement in Figure 8. If there is also a correspondence between the configuration information of
Petition 870190075528, of 08/06/2019, p. 40/84
35/70 resource 0 and the resource configuration information 2 that is used for interference measurement, the five matches can be referred to as a first match, and a match between a NZP CSI-RS feature in the feature 0 configuration information and a CSI-RS resource set in resource configuration information 2 are referred to as a second match.
[0069] Optionally, the network device can configure, in RRC signaling, the correspondence between a NZP CSI-RS resource used for channel measurement and a set of CSI-RS resource used for interference measurement. The RRC signaling can be the same or different from the RRC signaling to configure at least part of the CSI reporting configuration information.
[0070] Optionally, the network device configures, in dynamic signaling, the correspondence between a NZP CSI-RS resource used for channel measurement and a set of CSI-RS resource used for interference measurement. Dynamic signaling can be a media access control element (MAC-CE) or other layer 2 signaling. Dynamic signaling can alternatively be downlink control information control information, DCI).
[0071] Using the previous configuration, when an amount of coordinated base stations is increased, an amount of interference measurement hypotheses is also increased. In this case, the network device only needs to increase a number of CSI-RS resource sets
Petition 870190075528, of 08/06/2019, p. 41/84
36/70 of CSI resource reports or settings, so that a system can be scalable.
[0072] Optionally, the network device can also configure, in at least part of the CSI report configuration information, if the terminal device performs periodic reports. For example, the network device configures that the terminal device performs periodic reports, configures that the terminal device performs aperiodic reports, or configures that the terminal device performs semi-persistent reports (semipersistent).
[0073] Optionally, the network device can also configure, in the resource configuration information, that a CSI-RS resource is periodically sent, or that a CSI-RS resource is periodically sent, or that a CSI- RS is sent semi-persistently. The CSI-RS resource can be a NZP CSI-RS resource or a ZP CSIRS resource.
[0074] Step S202: The network device sends at least a portion of the CSI reporting configuration information and the resource configuration information corresponding to at least a portion of the CSI reporting configuration information to a terminal device.
[0075] Optionally, after sending at least a part of the CSI report configuration information and the resource configuration information corresponding to at least a part of the CSI report configuration information to the terminal device, the network device sends association indication information
Petition 870190075528, of 08/06/2019, p. 42/84
37/70 corresponding to at least a portion of the CSI reporting configuration information.
[0076] Optionally, after sending the indication of association information corresponding to at least a portion of the CSI report configuration information to the terminal device, the network device sends at least a portion of the CSI report configuration information and the resource configuration information corresponding to at least a portion of the CSI report configuration information.
[0077] Optionally, the network device simultaneously sends at least a part of the CSI report configuration information, the resource configuration information corresponding to at least a part of the CSI report configuration information and the indication of information association corresponding to at least a portion of the CSI reporting configuration information for the terminal device.
[0078] The network device can send at least a part of the CSI report configuration information and the resource configuration information corresponding to at least a part of the CSI report configuration information to the terminal device using RRC signaling . The network device can send the association indication information corresponding to at least a portion of the CSI report configuration information to the terminal device using RRC signaling.
[0079] If the network device sets up the correspondence between an NZP CSI-RS resource used for channel metering and a used CSI-RS resource set
Petition 870190075528, of 08/06/2019, p. 43/84
38/70 for interference measurement, the network device will send the correspondence between an NZP CSI-RS resource used for channel measurement and a set of CSI-RS resource used for interference measurement on the terminal device. The network device can send the correspondence using RRC signaling or dynamic signaling.
[0080] Step S203: The terminal device receives at least a portion of the CSI reporting configuration information and the resource configuration information corresponding to at least a portion of the CSI reporting configuration information that is sent by the network device .
[0081] Specifically, the terminal device can receive, using the RRC signaling, at least a part of the CSI report configuration information and the resource configuration information corresponding to at least a part of the CSI report configuration information , and can also receive, using the RRC signaling, the association indication information corresponding to at least a part of the CSI report configuration information. Upon receiving the configuration information, the terminal device can store the configuration information.
[0082] If the network device sends correspondence between an NZP CSI-RS resource used for channel measurement and a CSI-RS resource set used for interference measurement, the terminal device will still receive correspondence between a NZP CSI-RS used for channel measurement and a CSI-RS feature set used for interference measurement.
[0083] Step S204: The terminal device performs the
Petition 870190075528, of 08/06/2019, p. 44/84
39/70 measurement based on resource configuration information corresponding to at least part of the CSI report configuration information.
[0084] Specifically, the terminal device performs the measurement based on the resource configuration information that corresponds to at least part of the CSI report configuration information and that is used for channel measurement. For example, in Figure 7, the terminal device can perform the measurement based on the NZP CSI-RS (A) feature, to obtain a channel measurement result. / 0 channel measurement result can be used to calculate at least one of the parameters, such as a CQI, an RI, a PMI and a CRI.
[0085] The terminal device performs the measurement based on the resource configuration information that corresponds to at least part of the CSI report configuration information and that is used for interference measurement.
[0086] In a possible implementation, the terminal device can perform the measurement based on the M CSI-RS resource sets corresponding to at least part of the CSI report configuration information. In other words, the terminal device performs the measurement based on all CSI-RS resource sets configured by the network device.
[0087] For example, in Figure 7, the resource configuration 0 corresponding to the CSI report configuration 0 includes a NZP resource CSI-RS (A) used for channel measurement, the resource configuration 1 includes four resource sets CSI-RS, and each CSI-RS resource set
Petition 870190075528, of 08/06/2019, p. 45/84
40/70 includes at least one of a ZP CSI-RS (D) feature used for interference measurement and two NZP CSI-RS (B, C) features used for interference measurement. The terminal device can perform measurements based on the NZP CSI-RS (A) feature used for channel measurement and the four CSI-RS feature sets, to obtain four CSI reports. To be specific, the terminal device obtains a CSI report performing the measurement based on an NZP CSI-RS feature used for channel measurement and a set of CSI-RS feature used for interference measurement.
[0088] For another example, in Figure 8, the resource 0 setting corresponding to the CSI 0 reporting setting includes two NZP CSI-RS resources (A, B) used for channel measurement, resource 1 setting includes three CSI-RS resource sets and each CSI-RS resource set includes at least one of a ZP CSI-RS (D) resource used for interference measurement and two NZP CSI-RS (A, C) resources used for interference measurement. The end device can perform the measurement based on the NZP CSI-RS (A) feature used for channel measurement, the CSI-RS # 1 feature set, and the CSI-RS # 3 feature set, to obtain two CSI reports; and you can perform measurements based on the NZP CSI-RS (B) resource used for channel measurement and the three CSI-RS resource sets, to obtain three CSI reports. To be specific, the end device can obtain two CSI reports by performing measurements based on the CSI-RS # 1 feature set, can obtain a CSI report by performing measurements based on the CSIRS # 2 feature set, and can obtain two CSI reports performing measurements
Petition 870190075528, of 08/06/2019, p. 46/84
41/70 based on the CSI-RS # 3 feature set.
[0089] It can be understood that the possible implementation may correspond to the case in which the network device configures that the terminal device performs periodic reports, or it can correspond to the case in which the network device configures that the terminal device performs aperiodic reports, or may correspond to the case where the network device configures that the terminal device runs semi-persistent reports.
[0090] In a possible implementation, the terminal device can perform the measurement based on N of the M CSI-RS resource sets corresponding to at least part of the CSI report configuration information. The N CSI-RS resource sets can be indicated by the network device, N is a positive integer and 1 d N <M.
[0091] It can be understood that the possible implementation may correspond to the case where the network device configures that the terminal device runs periodic reports, or it can correspond to the case where the network device configures that the terminal device runs aperiodic reports, or may correspond to the case where the network device configures that the terminal device runs semi-persistent reports.
[0092] In a possible implementation, the terminal device can perform the measurement based on N of the M CSI-RS resource sets corresponding to at least part of the CSI report configuration information. An identifier for each of the N CSI-RS resource sets can be indicated by the network device, N is a positive integer and 1 d N <M.
Petition 870190075528, of 08/06/2019, p. 47/84
42/70 [0093] It can be understood that the possible implementation may correspond to the case where the network device configures that the terminal device performs aperiodic reports, or it can correspond to the case where the network device configures that the terminal device executes reports semi-persistent.
[0094] Specifically, the network device sends indication information of measurement resource to the terminal device. The measurement resource indication information instructs the terminal device to perform measurement based on the N CSI-RS resource sets, to be specific, measure the interference of the N CSI-RS resource sets. Upon receiving the measurement resource indication information, the terminal device performs the measurement based on the N CSI-RS resource sets.
[0095] Optionally, the measurement resource indication information can also indicate the identifier of each of the N CSI-RS resource sets.
[0096] Optionally, when a quantity of NZP CSI-RS resources included in the resource configuration information used for channel measurement is greater than 1, the measurement resource indication information may also indicate an identifier for an NZP resource CSI-RS corresponding to each of the N CSIRS resource sets, for example, indicate the CSI-RS # 2 resource set and the NZP CSP-RS (A) resource corresponding to the CSI-RS # resource set 2.
[0097] Optionally, when a quantity of NZP CSI-RS resources included in the resource configuration information used for channel measurement is greater than 1, the
Petition 870190075528, of 08/06/2019, p. 48/84
43/70 measurement resource indication information indicates a match identifier, for example, indicates match 1, to be specified, instructs the terminal device to perform measurements based on the NZP CSIRS resource (A) and the set of CSI-RS # 1 feature. In this case, the terminal device performs the measurement based on the NZP CSI-RS resource (A), the NZP CSI-RS resource (C) and the ZP CSI-RS resource (D).
[0098] The measurement resource indication information can be sent using dynamic signaling, and dynamic signaling can be a control element for access control to the medium (Media Access Control-Control Element, MAC-CE) or other signaling of media. layer 2. The dynamic signaling can alternatively be downlink control information, DCI.
[0099] When the amount of NZP CSI-RS resources included in the resource configuration information used for channel measurement is 1, the measurement resource indication information may indicate, in the following two ways, at least one the identifier of each of the N CSI-RS resource sets and the N CSI-RS resource sets.
[00100] Way 1: The N CSI-RS resource sets can be indicated using an S bit bitmap (bitmap). When a specific bit in the S bits is set, the terminal device is instructed to perform the measurement based on a CSI-RS resource set corresponding to the bit. A number of bits that are defined in the S bits is a value of N. Based on Figure 7, S represents a
Petition 870190075528, of 08/06/2019, p. 49/84
44/70 number of CSI-RS resource sets included in resource configuration 1 and the N CSI-RS resource sets are indicated using four bits. For example, 0001 indicates that N = 1 and indicates that the network device chooses to activate the CSI-RS # 1 resource set to instruct the terminal device to perform the measurement based on the CSI-RS # 1 resource set. For another example, 1010 indicates that N = 2, and the network device chooses to activate the CSI-RS # 4 feature set and the CSI-RS # 2 feature set, to instruct the terminal device to perform measurements based on in the CSI-RS # 4 feature set and the CSI-RS # 2 feature set.
[00101] Way 2: The N CSI-RS resource sets
ΑχΓζ ^ Ί can be indicated using ¹¹ bits. Based on Figure
7, N represents a number of CSI-RS resource sets required for interference measurement, S represents a number of CSI-RS resource sets included in resource configuration 1, and Γ Ί represents the calculation of the smallest integer greater than or equal to one
It is the result. ^{1 1} bits are used to indicate a sequence number for one of the CSI-RS resource sets, as shown in the following table:
Sequence number Recommendation of a set of 2-bit CSI-RS resource1 00 2 01 3 10 4 11
[00102] For example, two bits indicate that N = 1, two
Petition 870190075528, of 08/06/2019, p. 50/84
45/70 bits are used to indicate a CSIRS resource set and 11 indicates that the network device chooses to activate the CSI-RS # 4 resource set, to instruct the terminal device to perform measurements based on the resource set of CSI-RS # 4. For another example, four bits indicate that N = 2, four bits are used to indicate two sets of CSI-RS resources and 1101 indicates that the network device chooses to activate the set of CSI-RS # 4 and the set of CSI-RS # 2 feature, to instruct the terminal device to perform the measurement based on the CSI-RS # 4 feature set and the CSI-RS # 2 feature set.
[00103] In addition to the two previous ways, the network device can also perform the indication in another way of indicating, and a specific way of indicating used is not limited in this embodiment of the present invention. The indication method used by the network device can be notified in advance to the terminal device, so that a set of CSI-RS resources used by the terminal device for measurement is the same as a set of CSI-RS resources indicated by the network device .
[00104] The network device instructs the terminal device to selectively perform measurements and perform interference measurements based on the CSI-RS resource set, so that when the number of coordinated base stations is increased, the resource indication overheads measurement can be reduced.
[00105] Step S205: The terminal device sends a CSI measurement result to the network device.
[00106] Specifically, the terminal device sends the
Petition 870190075528, of 08/06/2019, p. 51/84
46/70 CSI measurement result for the network device. The CSI measurement result includes a CSI report and a CSI-RS resource set corresponds to at least one CSI report.
[00107] In a possible implementation, the CSI measurement result includes M 'CSI reports. To be specific, M 'CSI reports are reported to M
sets in CSI-RS resource, that is , fur any less one report in Corresponding CSI every one of all the sets in CSI-RS feature is reported . 0 results in
CSI measurement may further include an identifier for a CSI-RS resource set corresponding to each of the M 'CSI reports. As for the possible implementation, the terminal device performs the measurement based on the M CSI-RS resource sets by default, and reports all CSI reports by default.

[00127] When the amount of NZP CSI-RS resources included in the resource configuration information used for channel measurement is greater than 1, the report indication information may further instruct the terminal device to report an identifier from a corresponding match to each of the K CSI reports.
[00128] For the various previous optional ways, when the report indication information instructs the terminal device to report a CSI report, the indication can be performed using the information from [log ₂ l report indication using ^{1 1} bits. Based on Figure

[00129] When the amount of NZP CSI-RS resources included in the resource configuration information used
Petition 870190075528, of 08/06/2019, p. 59/84
54/70 for the channel measurement is equal to 1, the terminal device may indicate the CSI-RS resource set identifier in the following two ways:
[00130] Way 1: The terminal device indicates the identifier of the CSI-RS resource set using an N bit bitmap. Based on Figure 7, it is assumed that TRP 1 instructs the terminal device to perform the measurement based on the CSI-RS # 1 resource set for the CSI-RS # 4 resource set, that is, N = 4, and TRP 1 further instructs the terminal device to report a CSI report, that is, L = 1. In this case, the terminal device reports a CSI report and sets a bit from the CSI-RS resource set corresponding to the CSI on a 4-bit bitmap. For example, the CSI report reported by the terminal device corresponds to the CSI-RS # 3 feature set. In that case, when reporting the CSI report, the terminal device can report a 4-bit bitmap 0100, to indicate that a sequence number of the CSI-RS resource set corresponding to the CSI report is 3.
[00131] Based on Figure 7, TRP 1 is assumed to instruct the end device to perform interference measurement based on the CSI-RS # 1 resource set for the CSI-RS # 4 resource set, or that is, N = 4, and TRP 1 further instructs the terminal device to report two CSI reports, that is, L = 2. In this case, the terminal device reports two CSI reports and sets bits of CSI- RS corresponding to the two CSI reports on a 4-bit bitmap. For example, the two CSI reports reported by the device
Petition 870190075528, of 08/06/2019, p. 60/84
55/70 terminal corresponds to the CSI-RS # 1 resource set and the CSI-RS # 3 resource set. In this case, when reporting the two CSI reports, the terminal device can report a 4-bit bitmap 0101, to indicate that the sequence numbers of the CSI-RS resource sets corresponding to the two CSI reports are respectively 1 and 3.
[00132] Way 2: The terminal device indicates the identifier of the CSI-RS resource set using LxF / og ^ l ^{1 1} bits. Based on Figure 7, TRP 1 is presumed to instruct the terminal device to perform interference measurement based on the CSI-RS # 1 resource set for the CSI-RS # 4 resource set, that is, N = 4, and TRP 1 further instructs the terminal device to report a CSI report, that is, L = 1. In this case, the terminal device reports a CSI report and indicates, using two bits, an identifier for a set of CSI-RS resource corresponding to the CSI report. For example, the CSI report reported by the terminal device corresponds to the CSI-RS # 3 feature set. In this case, when reporting the CSI report, the terminal device can report two bits 10 (see the table in step S204), to indicate that a sequence number of the CSI-RS resource set corresponding to the CSI report is 3.
[00133] Based on Figure 7, TRP 1 is presumed to instruct the end device to perform interference measurement based on the CSI-RS # 1 resource set for the CSI-RS # 4 resource set, or that is, N = 4, and TRP 1 also instructs the terminal device to report
Petition 870190075528, of 08/06/2019, p. 61/84
56/70 two CSI reports, that is, L = 2. In this case, the terminal device reports two CSI reports and indicates, using four bits, identifiers of the CSI-RS resource sets corresponding to the two CSI reports. For example, the two CSI reports reported by the terminal device correspond to the CSI-RS # 1 resource set and the CSI-RS # 3 resource set. In this case, when reporting the two CSI reports, the terminal device can report four bits 0010, to indicate that the sequence numbers of the CSI-RS resource sets corresponding to the two CSI reports are 1 and 3 respectively.
[00134] In addition to the two preceding ways, the terminal device can also indicate the identifier of the CSI-RS resource set in another way, and a specific way used is not limited in this embodiment of the present invention.
[00135] The terminal device runs reports for the CSI-RS resource set and runs reports based on the report indication information, so that when the number of coordinated base stations is increased, the report overheads can be reduced.
[00136] Step S206: The network device receives the CSI measurement result sent by the terminal device.
[00137] Specifically, the network device receives the CSI measurement result sent by the terminal device and can determine a multi-base station coordinated transmission scheme, corresponding adaptive link configuration, and a programming policy based on the measurement result of CSI.
Petition 870190075528, of 08/06/2019, p. 62/84
57/70 [00138] In the embodiment shown in Figure 4, ο network device configures and sends at least a portion of the CSI report configuration information and the resource configuration information corresponding to at least a portion of the information from CSI reporting configuration, so that the terminal device performs the measurement based on the corresponding resource configuration information for at least a portion of CSI reporting configuration information. Therefore, when the number of coordinated base stations is increased, only the number of CSI-RS resource sets configured needs to be increased, and neither an amount of CSI reporting configuration information nor an amount of resource configuration information needs to be increased. be increased so that the system can be scalable. In addition, the same CSI-RS resource can be shared between a plurality of CSI-RS resource sets, so that downlink transmission resources can be saved, and a degree of sharing of a metering resource and a measurement result can be increased.
