Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and specifically to a CSI reporting indication method, configuration method, device and readable storage medium. Background Art

[0002] In the topic of network energy saving, it is necessary to study flexible antenna adaptation mechanisms to achieve energy saving. For example, when the business volume is small and the user throughput requirement is not high, some antenna arrays are turned off and only some antenna arrays are used to serve users, thereby achieving base station energy saving, which is called space / domain adaptation or antenna adaptation.

[0003] In order to achieve efficient transmission of user data, the base station must first obtain channel state information and perform matching scheduling. For the downlink channel, the network obtains the downlink channel state information by sending a channel state information reference signal (CSI-RS) resource and configuring the terminal to feedback the channel state information specified by the base station based on the CSI-RS resource. Therefore, in the case of antenna adaptation, the terminal needs to obtain the channel state information of different antenna adaptation patterns or spatial adaptation patterns. Currently, for spatial adaptation, it is considered to configure corresponding CSI-RS resources for different spatial adaptation patterns. Similarly, a matching CSI reporting configuration is also performed for each spatial adaptation pattern.

[0004] 1. The configuration of CSI-RS resources includes the following two methods:

[0005] A1-1-revised: Multiple CSI-RS resources in the same CSI resource set correspond to different spatial adaptation patterns, see Figure 1 .

[0006] A1-2-revised: A CSI-RS resource in the same CSI resource set corresponds to one or more adaptive patterns, see Figure 2 .

[0007] 2. For CSI reporting configuration, at least the following configurations are currently supported:

[0008] A2-2: A CSI reporting configuration contains multiple CSI reporting sub-configurations. Each CSI reporting sub-configuration corresponds to a spatial adaptive pattern. Figure 3 .

[0009] Based on the above CSI resource configuration and CSI reporting configuration, CSI reporting includes periodic reporting, semi-persistent (SP)-CSI reporting and aperiodic CSI reporting.

[0010] For non-periodic CSI and SP-CSI reporting, when carried on the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), reporting based on a trigger of the downlink control channel (Downlink Control Information, DCI) is supported.

[0077] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0078] The term "comprise" and any variation thereof in the specification and claims of the present application are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. In addition, the use of "and / or" in the specification and claims to indicate at least one of the connected objects, such as A and / or B, means that A alone, B alone, and A and B exist in three cases.

[0079] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0080] See also Figure 4 An embodiment of the present application provides a CSI reporting indication method, which is applied to a terminal, and the specific steps include: Step 401.

[0081] Step 401: In a CSI trigger state, a CSI reporting sub-configuration corresponding to the CSI trigger state is indicated by a first bitmap, the CSI reporting configuration associated with the CSI trigger state includes L CSI reporting sub-configurations, and a bitmap length of the first bitmap is an integer less than or equal to L.

[0082] For example, the first bitmap may indicate N CSI reporting subconfigurations corresponding to the CSI triggering state, that is, the first bitmap may indicate selecting N CSI reporting subconfigurations from L CSI reporting subconfigurations in the CSI reporting configuration, thereby achieving flexibility in CSI reporting configuration selection.

[0083] In one implementation of the present application, before, after, or simultaneously with indicating a CSI reporting subconfiguration corresponding to the CSI triggering state by a first bitmap in the CSI triggering state, the method further includes:

[0084] CSI reporting is performed through the CSI reporting subconfiguration indicated by the first bitmap.

[0085] In an implementation manner of the present application, performing CSI reporting through the CSI reporting subconfiguration indicated by the first bitmap includes:

[0086] Receive DCI;

[0087] Trigger or activate a CSI trigger state according to a CSI request field in the DCI;

[0088] CSI reporting is performed according to the CSI reporting subconfiguration corresponding to the CSI triggering state indicated by the first bitmap.

[0089] In this embodiment, the CSI request field in the DCI is multiplexed to implement the CSI reporting sub-configuration corresponding to the CSI triggering state indicated by the first bitmap.

[0090] In one implementation of the present application, there is a one-to-one correspondence between the L CSI sub-configurations and the bits in the first bitmap;

[0091] Wherein, when the bit in the first bitmap is the first value (for example, the first value is 1), the bit indicates that the current CSI triggering state includes the corresponding CSI reporting sub-configuration;

[0092] When the bit in the first bitmap is the second value (for example, the second value is 0), the bit indicates that the current CSI triggering state does not include the corresponding CSI reporting sub-configuration.

[0093] In an implementation manner of the present application, the first bitmap is a bitmap in a bitmap list, and each bitmap in the bitmap list indicates a CSI reporting sub-configuration corresponding to a CSI triggering state.

[0094] In one embodiment of the present application, the method further includes:

[0095] Get the current working status of the network side device;

[0096] According to the current working state of the network side device, select the corresponding first bitmap, where there is a corresponding relationship between the first bitmap and the working state of the network side device;

[0097] According to the first bitmap, a CSI reporting subconfiguration corresponding to the CSI triggering state in the current working state is determined.

[0098] In one implementation manner of the present application, the working state includes at least one of the following: energy saving mode, antenna working mode, antenna activation state, space adaptation state, space adaptation mode, power control offset value (powerControlOffset).

[0099] When a network side device (e.g., a base station) is configured with different powerControlOffsets, including a power offset value of a resource element (RE) of a physical downlink shared channel (PDSCH) compared to a CSI-RS RE, or a power offset value of a CSI-RS RE compared to a secondary synchronization signal (SSS) RE, the working state of the network side device may also correspond to a state in which different power offset values ​​are effective.

[0100] The above-mentioned state or mode does not mean to explicitly define the state or mode of the network side device, but refers to a working state of the network side device.

[0101] In another embodiment of the present application, the method further comprises:

[0102] Obtaining third information sent by the network side device;

[0103] According to the third information, selecting the corresponding first bitmap from the bitmap list, where there is a corresponding relationship between the bitmaps in the bitmap list and the values ​​of the third information;

[0104] Determine a CSI reporting subconfiguration corresponding to the CSI triggering state according to the first bitmap.

[0105] For example, when the third information takes the first value, it corresponds to the first bitmap in the bitmap list, when the third information takes the second value, it corresponds to the second bitmap in the bitmap list, and so on. When the third information takes the Nth value, it corresponds to the Nth bitmap in the bitmap list.

[0106] Optionally, the terminal obtains the first indication information sent by the network side device according to the working state of the network side device. In this way, the network side device does not need to let the terminal know the specific working mode or state of the network side device, but only needs to let the terminal and the network side device establish a corresponding relationship with the bitmap in the bitmap list through different values ​​of the first indication information, so that the two form a consistent understanding and determine the corresponding CSI reporting sub-configuration.

[0107] In one implementation manner of the present application, the CSI trigger state is a CSI aperiodic trigger state (CSI-AperiodicTriggerState), or the CSI trigger state is a CSI semi-persistent trigger state (CSI-SemiPersistentOnPUSCH-TriggerState).

[0108] In an implementation manner of the present application, all associated reporting configuration information (CSI-AssociatedReportConfigInfo) in the CSI aperiodic trigger state corresponds to the same bitmap.

[0109] That is, all associated reporting configuration information in the CSI aperiodic triggering state may share one bitmap.

[0110] The bitmap indicates the CSI reporting sub-configuration corresponding to the CSI triggering state.

[0111] In one embodiment of the present application, at least one CSI-associated reporting configuration information in the CSI-AperiodicTriggerState corresponds to a bitmap, for example, a bitmap is independently configured for each CSI-AssociatedReportConfigInfo to select a CSI reporting sub-configuration, allowing greater flexibility, that is, M (M is usually a maximum of 16, not limited here) CSI-AssociatedReportConfigInfo can correspond to their own bitmaps, respectively, to achieve the selection of CSI reporting sub-configurations corresponding to different spatial adaptive patterns. In this case, the CSI reporting configuration corresponding to each CSI-AssociatedReportConfigInfo in the M CSI-AssociatedReportConfigInfo may have different L sub-configurations, that is, the L value may be different in different CSI reporting configurations. In this case, the length of the bitmap in each CSI-AssociatedReportConfigInfo may also be different, and the length is determined by the number of CSI reporting sub-configurations in the CSI reporting configuration to which it is associated. This method of independently configuring the bitmap can achieve the most flexible selection of CSI reporting sub-configurations.

[0112] When CSI-AperiodicTriggerState includes M CSI-AssociatedReportConfigInfo, it is also possible to configure a bitmap for only part of the CSI-AssociatedReportConfigInfo, and not configure a bitmap for other CSI-AssociatedReportConfigInfo, but use all L CSI reporting sub-configurations, which is also allowed.

[0113] In the present application, the CSI reporting sub-configuration corresponding to the CSI trigger state is indicated by the first bitmap in the CSI trigger state, the CSI reporting configuration associated with the CSI trigger state includes L CSI reporting sub-configurations, and the bitmap length of the first bitmap is an integer less than or equal to L. The first bitmap can be used to flexibly select the CSI reporting sub-configuration.

[0114] See also Figure 5 , an embodiment of the present application provides a CSI reporting configuration method, which is applied to a network side device, and the specific steps include: step 501.

[0115] Step 501: Send first information, where the first information is used to configure the terminal to indicate a CSI reporting sub-configuration corresponding to the CSI trigger state through a first bitmap in a CSI trigger state, the CSI reporting configuration associated with the CSI trigger state includes L CSI reporting sub-configurations, and a bitmap length of the first bitmap is an integer less than or equal to L.

[0116] In one implementation of the present application, after sending the first information, the method further includes:

[0117] Receive the CSI reported by the terminal through the CSI reporting subconfiguration indicated by the first bitmap.

[0118] In one embodiment of the present application, before, after, or simultaneously with step 501, the method further includes:

[0119] A DCI is sent, where the CSI request field in the DCI is used to trigger or activate a CSI triggering state.

[0120] In one implementation of the present application, there is a one-to-one correspondence between the L CSI reporting sub-configurations and the bits in the first bitmap;

[0121] Wherein, when the bit in the first bitmap is the first value, the bit indicates that the current CSI triggering state includes the corresponding CSI reporting sub-configuration;

[0122] When the bit in the first bitmap is the second value, the bit indicates that the current CSI triggering state does not include the corresponding CSI reporting sub-configuration.

[0123] In an implementation manner of the present application, the first bitmap is a bitmap in a bitmap list, and each bitmap in the bitmap list indicates a CSI reporting sub-configuration corresponding to a CSI triggering state.

[0124] In one implementation of the present application, there is a corresponding relationship between the bitmap in the bitmap list and the working status of the network side device.

[0125] In one embodiment of the present application, before, after, or simultaneously with sending the first information, the method further includes:

[0126] sending a second message;

[0127] The second information is used to indicate the current working status of the network side device; or, there is a corresponding relationship between the second information and the current working status of the network side device.

[0128] In one embodiment of the present application, before, after, or simultaneously with sending the first information, the method further includes:

[0129] Send third information, where the third information is used to select the corresponding first bitmap from the bitmap list, and there is a corresponding relationship between the bitmaps in the bitmap list and the values ​​of the third information.

[0130] For example, the network side device sends the third information according to the working status of the network side device.

[0131] In one implementation of the present application, the working state includes at least one of the following: energy saving mode, antenna working mode, antenna activation state, spatial adaptation state, spatial adaptation mode, and power control offset value.

[0132] In an implementation manner of the present application, the CSI trigger state is CSI-AperiodicTriggerState, or the CSI trigger state is CSI-SemiPersistentOnPUSCH-TriggerState.

[0133] In one implementation of the present application, all associated reporting configuration information in the CSI-AperiodicTriggerState corresponds to the same bitmap;

[0134] or,

[0135] At least one CSI-related reporting configuration information in the CSI-AperiodicTriggerState corresponds to a bitmap;

[0136] The bitmap indicates the CSI reporting sub-configuration corresponding to the CSI triggering state.

[0137] In the present application, a network side device sends a first information, and the first information is used to configure the terminal to indicate the CSI reporting sub-configuration corresponding to the CSI trigger state through a first bitmap in the CSI trigger state, and the CSI reporting configuration associated with the CSI trigger state includes L CSI reporting sub-configurations, and the bitmap length of the first bitmap is an integer less than or equal to L. The first bitmap can be used to achieve flexible selection of the CSI reporting sub-configuration.

[0138] The implementation method of the present application is introduced below in combination with Example 1 and Example 2.

[0139] Embodiment 1: triggering or activating non-periodic CSI reporting.

[0140] Because the downlink control information (Downlink Control Information, DCI) selects a state to be activated from the CSI-AperiodicTriggerState configured by the Radio Resource Control (Radio Resource Control, RRC), or selects a state to be activated from a maximum of 64 CSI-AperiodicTriggerStates after the Medium Access Control Control Element (Medium Access Control Control Element, MAC-CE) sub selection.

[0141] Each CSI-AperiodicTriggerState contains up to 16 reporting configurations for aperiodic reporting, namely "CSI-AssociatedReportConfigInfo", and each CSI-AssociatedReportConfigInfo gives the CSI reporting configuration used and the corresponding CSI-RS resources. When DCI selects a CSI-AperiodicTriggerState, the corresponding up to 16 CSI reporting configurations are also determined accordingly. Therefore, one implementation method is to configure N1 CSI reporting sub-configurations in the CSI-ReportConfig whose reporting configuration type (reportConfigType) is aperiodic.

[0142] For different CSI-AperiodicTriggerState, the corresponding aperiodic CSI-ReportConfig is configured with N2 CSI reporting sub-configurations, N1 can be equal to N2 or different. When a certain aperiodic trigger state (aperiodic trigger state) is triggered by DCI, the N2 CSI reporting sub-configurations in the corresponding CSI-ReportConfig are selected accordingly.

[0143] The above solution needs to determine which of the L spatial adaptive patterns it corresponds to when configuring each CSI-ReportConfig. When the base station wants to adjust the corresponding spatial adaptive patterns in certain CSI-ReportConfigs, it needs to release these CSI-ReportConfigs and then reconfigure them. And these CSI-ReportConfigs already correspond to the determined N CSI reporting sub-configurations, which is not conducive to being reused by different non-periodic trigger states.

[0144] Furthermore, this embodiment also provides a more flexible configuration method, which does not require modification of the configuration in CSI-ReportConfig, that is, L CSI reporting sub-configurations are still configured in CSI-ReportConfig, corresponding to L spatial adaptive patterns.

[0145] N CSI reporting sub-configurations are selected by means of the first bitmap in CSI-AperiodicTriggerState. The bitmap length of the first bitmap is an integer less than or equal to L. If the bitmap length of the first bitmap is an integer equal to L, for all L CSI reporting sub-configurations in the CSI report, a bit in the first bitmap of "1" indicates that the corresponding CSI reporting sub-configuration is selected, and CSI feedback of the corresponding CSI reporting sub-configuration is required. A bit in the first bitmap of "0" indicates that it is not selected by the current trigger state, and CSI feedback of the corresponding sub-configuration is not required.

[0146] This method determines N types of CSI reporting sub-configurations corresponding to the current state in the non-periodic trigger state, and different non-periodic trigger states can be associated with the same CSI report. Only by changing the value of the first bitmap, for example, changing the bitmap value of the CSI reporting sub-configuration selection parameter (subConfigSelection), the effect of triggering the CSI reporting sub-configuration corresponding to different spatial adaptive patterns can be achieved.

[0147] All "CSI-AssociatedReportConfigInfo" in the same CSI-AperiodicTriggerState triggered in this way select the same N CSI reporting sub-configurations. There is a one-to-one correspondence between the L CSI reporting sub-configurations of all CSI-Reports and the bits in the first bitmap used for CSI reporting sub-configuration selection in CSI-AperiodicTriggerState.

[0148] Another implementation method is to select the CSI reporting sub-configuration in CSI-AssociatedReportConfigInfo (select N from L CSI reporting sub-configurations, 1<=N<=L). A CSI-ReportConfig is associated with the CSI-AssociatedReportConfigInfo through the CSI reporting configuration identifier (CSI-ReportConfigId). L CSI reporting sub-configurations are configured in this CSI-ReportConfig. Therefore, a first bitmap is introduced in CSI-AssociatedReportConfigInfo to select the CSI reporting sub-configuration of the associated CSI-ReportConfig. The bitmap length of the first bitmap is an integer less than or equal to L, where L can represent the maximum number of spatial adaptation patterns (maxNrofSpatialAdaptionPattern). When the bitmap length of the first bitmap is L, it can correspond to all L CSI reporting sub-configurations in the CSI report. A bit in the first bitmap of "1" indicates that the corresponding CSI reporting sub-configuration is selected, and CSI feedback of the corresponding CSI reporting sub-configuration is required. A bit in the first bitmap of "0" indicates that it is not selected by the current trigger state, and CSI feedback of the corresponding CSI reporting sub-configuration is not required.

[0149] Since CSI-AperiodicTriggerState contains a maximum of 16 "CSI-AssociatedReportConfigInfo", each CSI-AssociatedReportConfigInfo independently configures the first bitmap for CSI reporting sub-configuration selection, allowing greater flexibility, that is, the 16 CSI-AssociatedReportConfigInfo can respectively implement the selection of CSI reporting sub-configurations corresponding to different spatial adaptation patterns.

[0150] Furthermore, considering the original maximum of 128 CSI-AperiodicTriggerStates, different spatial adaptive patterns were not considered in the design. These aperiodic trigger states correspond to different aperiodic trigger states under the same antenna configuration, for example, they may correspond to different report quantities, different CSI-RS resources, different report frequency configurations, and other parameters in the CSI report config. If the states in 128 are used to select different CSI reporting sub-configurations, the flexibility of the corresponding CSI-AperiodicTriggerState configuration becomes poor.

[0151] In order to maintain the flexibility of the CSI-AperiodicTriggerState configuration, this embodiment also provides for introducing multiple bitmaps for CSI reporting sub-configuration selection in the above-mentioned CSI-AperiodicTriggerState or CSI-AssociatedReportConfigInfo. That is, a bitmap list for CSI reporting sub-configuration selection is introduced. Each bitmap for CSI reporting sub-configuration selection in the bitmap list can select a different CSI reporting sub-configuration.

[0152] Each bitmap (e.g., the first bitmap) in the bitmap list for selecting a CSI reporting sub-configuration may correspond to a working state of a network side device. Optionally, the working state of the network side device may include at least one of the following: energy saving mode, antenna working mode, activated antenna state, spatial adaptation state, spatial adaptation pattern, power control offset value (powerControlOffset), that is, different working states may correspond to different working modes, such as different energy saving states, different antenna working modes, different numbers of activated antennas, different spatial adaptation states, different spatial adaptation patterns, etc. The above-mentioned state or mode does not mean that the state or mode is explicitly defined, but refers to a working state.

[0153] For example, when the base station operates in the spatial adaptation mode 1, for 128 types of CSI-AperiodicTriggerState, it is more desirable to trigger aperiodic reporting of certain CSI reporting sub-configurations.

[0154] For example, if the base station is currently operating in the 64TxRU state, the non-periodic triggering of the base station would prefer to obtain the channel status of the 64TxRU and the case where half of the TxRU is turned off. When the base station is in the 8TxRU state, it would prefer to obtain whether half of the antenna can be turned off again, or the channel status of the 64TxRU case can be restored.

[0155] Therefore, in the multiple bitmap lists for CSI reporting sub-configuration selection introduced in CSI-AperiodicTriggerState or CSI-AssociatedReportConfigInfo, the first CSI reporting sub-configuration selected bitmap in the bitmap list is used for base station working state 1, the second CSI reporting sub-configuration selected bitmap is used for base station working state 2, and so on.

[0156] Step 1: According to the current base station working state, a CSI reporting sub-configuration selection bitmap (eg, the first bitmap) corresponding to the base station working state in the CSI reporting sub-configuration selection bitmap list can be matched.

[0157] Optionally, the terminal may obtain the working status of the current base station through an explicit indication of the base station or through an implicit corresponding relationship.

[0158] (1) The base station explicitly indicates through MAC-CE or DCI to use a CSI reporting sub-configuration selection bitmap (for example, the first bitmap) in the sub-configuration selection bitmap list.

[0159] (2) The corresponding bitmap (eg, the first bitmap) for selecting the CSI reporting sub-configuration is implicitly determined through the switching indication of the working state of the base station.

[0160] Step 2: All CSI-AperiodicTriggerStates determine the corresponding CSI reporting sub-configuration selection bitmap (eg, the first bitmap) according to the base station working state, and the CSI reporting sub-configuration corresponding to the CSI-AperiodicTriggerState in the current base station working state can be determined.

[0161] Step 3: A CSI-AperiodicTriggerState can be triggered through the CSI request field in the DCI;

[0162] Step 4: The UE reports CSI according to the selected CSI reporting subconfiguration in the CSI reporting configuration (CSI reportconfig) corresponding to the CSI-AperiodicTriggerState, and uses the measurement resources in the CSI report config to perform measurement.

[0163] Embodiment 2: Activation of semi-persistent CSI reporting on the PUSCH.

[0164] For the semi-persistent CSI reporting of PUSCH, activation or deactivation of the CSI semi-persistent CSI trigger state is achieved through the CSI request field in DCI format 0_1 ​​or DCI format 0_2.

[0165] The network configures up to 64 CSI semi-persistent trigger states (CSI-SemiPersistentOnPUSCH-TriggerState) through RRC signaling.

[0166] Therefore, for the implementation method of selecting N types of CSI reporting sub-configurations from L types of CSI reporting sub-configurations in CSI-ReportConfig, a similar method to aperiodic CSI reporting may be referred to.

[0167] One is to configure N CSI reporting sub-configurations in CSI-ReportConfig with reportConfigType being semiPersistentOnPUCCH. The N CSI reporting sub-configurations configured in CSI-ReportConfig with different reportConfigType being semiPersistentOnPUCCH can be the same or different, and even the N value can be different.

[0168] Since CSI-SemiPersistentOnPUSCH-TriggerState is associated with a CSI-ReportConfig, different CSI-SemiPersistentOnPUSCH-TriggerStates are selected through the CSI request field in DCI format 0_1 ​​or DCI format 0_2, and N CSI reporting sub-configurations in the corresponding CSI-ReportConfig are selected accordingly.

[0169] Similarly, in order to improve the flexibility of configuration, L types of CSI reporting sub-configurations are still configured in CSI-ReportConfig, corresponding to L types of spatial adaptive patterns. N types of CSI reporting sub-configurations are selected by means of the first bitmap in CSI-SemiPersistentOnPUSCH-TriggerState. The bitmap length of the first bitmap is an integer less than or equal to L. When the length of the first bitmap is an integer equal to L, for all L types of CSI reporting sub-configurations in the CSI report, a bit in the first bitmap of "1" indicates that the corresponding CSI reporting sub-configuration is selected and CSI feedback of the corresponding CSI reporting sub-configuration is required. A bit in the first bitmap of "0" indicates that it is not selected by the current trigger state, and CSI feedback of the corresponding CSI reporting sub-configuration is not required.

[0170] Similar to the case of non-periodic CSI reporting, multiple bitmaps for CSI reporting sub-configuration selection can also be introduced in CSI-SemiPersistentOnPUSCH-TriggerState. That is, a bitmap list for CSI reporting sub-configuration selection is introduced. Each bitmap for CSI reporting sub-configuration selection in the bitmap list can select a different CSI reporting sub-configuration.

[0171] Each bitmap for CSI reporting sub-configuration selection may correspond to a base station working state (the base station working state may correspond to at least one of the energy saving mode, antenna working mode, activated antenna state, spatial adaptation state, spatial adaptation pattern, and power control offset value (powerControlOffset), that is, different working states may correspond to different network working modes, such as different energy saving states, different antenna working modes, different numbers of activated antennas, different spatial adaptation states, different spatial adaptation patterns, etc. The above states or modes do not mean that the states or modes are explicitly defined, but refer to a working state). For example, when the base station works in spatial adaptation mode 1, for the 64 CSI-SemiPersistentOnPUSCH-TriggerStates, it is more desirable to trigger the semi-persistent CSI reporting of certain sub configurations.

[0172] For example, if the base station is currently operating in the 64TxRU state, the base station would like to obtain the channel state of the 64TxRU and half of the TxRUs when the semi-persistentCSI report is turned off. When the base station is in the 8TxRU state, it would like to obtain whether it can turn off half of the antenna or restore the channel state to the 64TxRU state.

[0173] Therefore, in the bitmap list for CSI reporting sub-configuration selection introduced in CSI-SemiPersistentOnPUSCH-TriggerState, the first CSI reporting sub-configuration selected bitmap in the bitmap list is used for base station working state 1, the second CSI reporting sub-configuration selected bitmap is used for base station working state 2, and so on.

[0174] Step 1: According to the current base station working state, a CSI reporting sub-configuration selection bitmap (eg, the first bitmap) corresponding to the base station working state in the CSI reporting sub-configuration selection bitmap list can be matched.

[0175] The terminal can obtain the working status of the current base station through explicit instructions from the base station or through implicit correspondence.

[0176] (1) The base station explicitly indicates through MAC-CE or DCI to use a CSI reporting sub-configuration selection bitmap (for example, the first bitmap) in the sub-configuration selection bitmap list.

[0177] (2) The corresponding bitmap (eg, the first bitmap) for selecting the CSI reporting sub-configuration is implicitly determined through the switching indication of the working state of the base station.

[0178] Step 2: All CSI-SemiPersistentOnPUSCH-TriggerStates determine the corresponding CSI reporting sub-configuration selection bitmap (e.g., the first bitmap) according to the base station working state, and then the CSI reporting sub-configuration corresponding to the CSI-SemiPersistentOnPUSCH-TriggerState in the current base station working state can be determined.

[0179] Step 3: Through the CSI request field in the DCI, a CSI-SemiPersistentOnPUSCH-TriggerState can be activated or deactivated;

[0180] Step 4: The UE reports CSI according to the selected CSI reporting sub-configuration in the CSI reporting configuration corresponding to the CSI-SemiPersistentOnPUSCH-TriggerState, and performs measurement using the measurement resources in the CSI reporting configuration.
