[0036] In a first aspect, an embodiment of the present disclosure provides a method for activating a channel state information (CSI) report configuration, wherein the method is performed by a terminal. The method includes:

[0037] The network device sends a media access control MAC control unit CE to the terminal, where the MAC CE is used to activate or deactivate a CSI report configuration, where the CSI report configuration includes a first type of report configuration and / or a second type of report configuration; the first type of report configuration includes one or more sub-configurations.

[0038] In the above embodiment, the network device can activate different types of CSI report configurations by sending a MAC CE-based message to the terminal. When the activated CSI report configuration is the first type of report configuration, the activation or deactivation of the sub-configuration granularity can also be achieved, thereby reducing the measurement power consumption of the terminal and saving bit overhead.

[0039] In combination with some embodiments of the first aspect, in some embodiments, the MAC CE includes:

[0040] The first indication bit is used to indicate activation or deactivation of the CSI report configuration;

[0041] The second indication bit is used by the terminal to determine activation or deactivation of a sub-configuration in the activated first type of reporting configuration.

[0042] In the above embodiment, an indication bit indicating activation or deactivation of a sub-configuration is introduced into the MAC CE, so that activation or deactivation indication at a sub-configuration granularity can be implemented.

[0043] In combination with some embodiments of the first aspect, in some embodiments, the length of the MAC CE is variable, and the length of the MAC CE is related to the activated CSI reporting configuration.

[0044] In the above embodiment, the length of the MAC CE is variable, and the length of the MAC CE is related to the activated CSI report configuration. In this way, on the one hand, the required CSI report configuration can be activated through the MAC CE, and the length of the MAC CE is related to the activated CSI report configuration rather than a fixed length, which can reduce unnecessary bit waste.

[0045] In combination with some embodiments of the first aspect, in some embodiments, the first indication bit is located in the first octet of the MAC CE; the second indication bit is located in the second octet of the MAC CE.

[0046] Based on the above scheme, a bit distribution example of a MAC CE is given, which has the characteristics of high effective utilization rate of the bits of the MAC CE and simple implementation.

[0047] In combination with some embodiments of the first aspect, in some embodiments, a second octet is used for sub-configuration activation of an activated first-class reporting configuration.

[0055] Based on the above scheme, the second indication bit can use a bit map or a joint indication method to indicate the activation or deactivation of the configuration. When the activated CSI report configuration is the second type of sub-configuration, the value of the corresponding octet is simple to implement.

[0056] In conjunction with some embodiments of the first aspect, in some embodiments, the length of the MAC CE is constant;

[0057] The second indication bit is used to indicate activation or deactivation of the sub-configuration of the activated first-type reporting configuration.

[0061] In the above embodiment, the terminal receives the first MAC CE sent by the network device and uses the first information in the first MAC CE to indicate the activation or deactivation of the sub-configuration, thereby realizing the activation or deactivation of a finer-grained CSI report configuration, thereby reducing the measurement power consumption of the terminal and saving bit overhead.

[0062] In combination with some embodiments of the second aspect, in some embodiments, the MAC CE includes:

[0063] The first indication bit is used to indicate activation or deactivation of the CSI report configuration;

[0064] The second indication bit is used by the terminal to determine activation or deactivation of a sub-configuration in the activated first type of reporting configuration.

[0065] In combination with some embodiments of the second aspect, in some embodiments, the length of the MAC CE is variable, and the length of the MAC CE is related to the activated CSI reporting configuration.

[0066] In combination with some embodiments of the second aspect, in some embodiments, the first indication bit is located in the first octet of the MAC CE; the second indication bit is located in the second octet of the MAC CE.

[0067] In combination with some embodiments of the second aspect, in some embodiments, a second octet is used for sub-configuration activation of an activated first-class reporting configuration.

[0068] In conjunction with some embodiments of the second aspect, in some embodiments, a second octet corresponds to an activated CSI reporting configuration;

[0069] When the activated CSI report configuration corresponding to the nth second octet is the second type of report configuration, the nth second octet has a first value, where n is a positive integer.

[0070] In combination with some embodiments of the first aspect, in some embodiments, when one bit in the nth second octet is used to indicate a subconfiguration, the value of each bit in the nth second octet is “0” or the value of each bit in the nth second octet is “1”;

[0071] or,

[0072] When a bit value of the nth second octet is used to indicate a combination of activation or deactivation of at least one sub-configuration, a first value of the nth second octet is a set value.

[0132] R: indicates a reserved field, and the bit value is set to 0.

[0133] Figure 2 FIG. 1 is an interactive diagram of a method for activating a channel state information (CSI) report configuration according to an exemplary embodiment. Figure 2 As shown, the embodiment of the present disclosure relates to a method for activating a channel state information CSI report configuration, which is used in a communication system 100, and the method includes:

[0134] Step S2101: The network device sends a MAC CE to the terminal.

[0135] In some embodiments, the terminal receives a MAC CE sent by a network device.

[0136] In some embodiments, the network device may include but is not limited to an access network device.

[0137] In some embodiments, the terminal may be various types of communication devices. The terminal may be a mobile terminal or a fixed terminal. For example, the terminal may be a mobile phone, a tablet computer, a smart office device, a smart home device, a vehicle-mounted device, and / or an aircraft device.

[0138] In some embodiments, the MAC CE may be used to activate or deactivate a semi-persistent channel state information (SP-CSI) reporting configuration or an aperiodic CSI reporting configuration.

[0139] In some embodiments, the type of MAC CE may include one of the following:

[0140] The first type of MAC CE is used to activate or deactivate the reporting of CSI reports with sub-configuration granularity, that is, the first MAC CE can be used for activation or deactivation of the first type of reporting configuration, but not for activation or deactivation of the second type of reporting configuration.

[0141] The second type of MAC CE is used to activate or deactivate the reporting of CSI reports with CSI report configuration as the granularity, that is, the second MAC CE can be used for activation or deactivation of the second type of report configuration, but not for activation or deactivation of the first type of report configuration.

[0142] The third type of MAC CE can be used for activation or deactivation of the first type of reporting configuration, and can also be used for activation or deactivation of the second type of reporting configuration.

[0143] In some embodiments, the MAC CE sent by the network device may be used for activation or deactivation of the first type of reporting configuration and / or the second type of reporting configuration.

[0144] In some embodiments, the MAC CE sent by S2101 may be any one of the above.

[0145] Optionally, the MAC CE sent by the network device in the embodiment of the present disclosure may be a third type of MAC CE.

[0146] In some embodiments, the CSI report configuration is used for CSI measurement and / or CSI measurement reporting of the terminal.

[0147] In some embodiments, the terminal performs CSI measurement according to the CSI report configuration, and performs reporting only when the reporting condition is met. The reporting here is to send the measured CSI information to the network device.

[0148] In some embodiments, the CSI report configuration may include at least one of the following:

[0149] Time-frequency resource information of the measured reference signal;

[0150] Indication information of the reported quantity.

[0151] In some embodiments, a sub-configuration may include one or more of the following:

[0152] Transmission parameters of the measured reference signal, including but not limited to time-frequency resource location, whether beam transmission is used, and / or transmission direction when beam transmission is used, etc.;

[0153] Indication information of the reported quantity.

[0154] In some embodiments, the reporting amounts defined by different sub-configurations may be the same or different.

[0155] In some embodiments, the network device may send one or more CSI report configurations; different CSI report configurations may correspond to different CSI resource configurations; multiple CSI report configurations may correspond to the same CSI resource configuration; the CSI report configuration may include a semi-static CSI report configuration, a dynamic CSI report configuration and / or a periodic CSI report configuration. Among them, the dynamic CSI report configuration may also be called a non-periodic CSI report configuration; different CSI report configurations may have different identifiers.

[0156] In some embodiments, different sub-configurations may correspond to the same CSI resource configuration and / or different CSI resource configurations.

[0157] In some embodiments, the CSI reporting configuration includes a first type of reporting configuration and / or a second type of reporting configuration.

[0158] In some embodiments, the first type of reporting configuration may be an enhanced reporting configuration based on the second type of reporting configuration.

[0159] In some embodiments, the first type of reporting configuration may be an enhanced CSI reporting configuration.

[0160] In some embodiments, the second type of report configuration may be a legacy CSI report configuration (reportconfig).

[0161] In some embodiments, the first type of reporting configuration includes one or more sub-configurations.

[0162] In some embodiments, the second type of reporting configuration does not include sub-configurations.

[0163] In some embodiments, the sub-configuration corresponds to a spatial pattern (SD) element and / or transmit power consumption.

[0164] It should be noted that each first-type reporting configuration may include multiple sub-configurations; each sub-configuration may be associated with a spatial pattern (spatial pattern, SD) and / or multiple power consumption (power) standards.

[0165] In some embodiments, the first type of reporting configuration may include a first parameter. In some embodiments, the first parameter may be referred to as a legacy parameter for performing CSI measurement reporting without distinguishing between SD and / or transmission power.

[0166] In some embodiments, the first parameter may be a common CSI parameter that is not included in any sub-report.

[0167] In some embodiments, the first parameter may be a CSI parameter included in a specific sub-configuration in the first type of reporting configuration. Exemplarily, the specific sub-configuration may be a default sub configuration.

[0168] In some embodiments, the first parameter may indicate a reference signal for performing CSI measurement, a resource location of the reference signal, a reporting amount and / or a reporting condition.

[0169] In the embodiment of the present disclosure, the MAC CE includes: a first indication bit for indicating activation or deactivation of the CSI reporting configuration, and a second indication bit for the terminal to determine activation or deactivation of a sub-configuration in the activated first type of reporting configuration.

[0170] In some embodiments, the MAC CE sent by the network device may include one or more bitmaps.

[0171] In some embodiments, the MAC CE sent by the network device may include multiple octets.

[0172] In some embodiments, an octet may include 8 bits.

[0173] In some embodiments, at least one second indication bit is a bitmap, wherein one bit in the bitmap is used to indicate activation or deactivation of a subconfiguration.

[0174] It should be noted that at least one second indication bit can indicate the activation or deactivation of at least one sub-configuration in the first type of reporting configuration by means of a bitmap. Each bit in the bitmap corresponds to a sub-configuration, and different bits carry specific bit values ​​to indicate the activation or deactivation of the sub-configuration corresponding to the bit.

[0175] It is worth noting that the method of indicating the activation or deactivation of the sub-configuration based on the bit map can effectively reduce the decoding complexity of the second indication bit in the first MAC CE. However, since one bit in the bit map corresponds to one sub-configuration, the number of sub-configurations that can be indicated by the second indication bit in the first MAC CE is limited by the number of second indication bits in the MACCE.

[0176] In some embodiments, the second indication bit may indicate a combined state of activation or deactivation of one or more sub-configurations in a first type of reporting configuration by means of a joint indication. For example, at this time, a value of the plurality of second indication bits may correspond to a combined state of activation or deactivation of sub-configurations in the first type of reporting configuration, and different values ​​correspond to different combined states.

[0177] In some embodiments, the header and the payload of the MAC protocol data unit (PDU) in which the MAC CE is located. The header of the header MAC sub-PDU may include an LCID field, and the LCID carried in the LCID field may be used. The first indication bit and the second indication bit may be included in the payload.

[0178] In some embodiments, the second indication bit may be a reserved bit within the MAC CE.

[0179] like Figure 1B The illustrated MAC CE may include two octets.

[0180] The first octet (oct 1) has 1 reserved bit, and the second octet (oct 2) has 4 reserved bits. Oct 2 also has 4 bits for indicating activation or deactivation of the CSI report configuration, which are the first indication bits.

[0181] The reserved bits of oct 1 and / or oct 2 can both be used as the second indication bits.

[0182] Oct 1 is also used to indicate the serving cell identifier and / or the partial bandwidth BWP identifier. For example, 2 bits in Oct 1 are used to indicate the BWP identifier, and 5 bits in Oct 1 are used to indicate the cell identifier. The cell identifier is used to identify the cell that sends the MAC CE, or to identify the cell in which the MAC CE is effective.

[0183] For example, the reserved bits in oct 1 and oct 2 can both be used as the second indication bit, and the bit distribution of MAC CE can be as follows: Figure 3A As shown. Figure 3A Where Ni represents the second indication bit, and the value of i is 0 to 4. Figure 3AIn , Sj represents the first indication bit, and the value range of j is 0 to 3.

[0184] For example, the reserved bits in oct 2 can all be used as the second indication bits, and the bit distribution of MAC CE can be as follows: Figure 3B As shown. Figure 3A Where Ni represents the second indication bit, and the value of i is 0 to 3. Figure 3A In , Sj represents the first indication bit, and the value range of j is 0 to 3.

[0185] In some embodiments, the numbers of the second indication bits indicating the sub-configuration in the MAC CE are sorted from high to low according to the identifier of the sub-configuration, or the numbers of the second indication bits indicating the sub-configuration in the MAC CE are sorted from low to high according to the identifier of the sub-configuration.

[0186] In some embodiments, the numbers of the second indication bits indicating the sub-configuration in the MAC CE are sorted from front to back in the CSI reporting configuration according to the sub-configuration, or the numbers of the second indication bits indicating the sub-configuration in the MAC CE are sorted from back to front in the CSI reporting configuration according to the sub-configuration.

[0187] In some embodiments, the CSI report configuration may be sent by an RRC message. The RRC message may carry one or more information elements (IEs). Assuming that an IE configures a CSI report configuration, the position of a sub-configuration in the IE determines the context of the sub-configuration among multiple sub-configurations. Assuming that an IE configures multiple CSI report configurations, the position of a sub-configuration in the IE depends on both the position of the CSI report configuration in the IE and its own position in the CSI report configuration.

[0188] like Figure 3A and 3B As shown, the MAC CE may include more than two octets, in which case the bits included in the octet of oct3 of the MAC CE may all be second indication bits.

[0189] In some embodiments, the length of the MAC CE is variable.

[0190] In some embodiments, when the length of the MAC CE is variable, the MAC CE may include two or more octets.

[0191] In some embodiments, when the length of the MAC CE is variable, the MAC CE may include oct3, which can be used to indicate activation or deactivation of a sub-configuration.

[0192] In some embodiments, when the number of the second indication bits in the MAC CE is greater than the number of sub-configurations included in the activated CSI report configuration, the excess second indication bits have a first value. Exemplarily, the first value may be "0".

[0193] When the activated CSI report configuration corresponding to the nth second octet is the second type of report configuration, the nth second octet has a first value, where n is a positive integer.

[0194] In combination with some embodiments of the first aspect, in some embodiments, when a bit in the nth second octet is used to indicate a sub-configuration, the value of each bit in the nth second octet is "0" or the value of each bit in the nth second octet is "1".

[0195] When a bit value of the nth second octet is used to indicate a combination of activation or deactivation of at least one sub-configuration, a first value of the nth second octet is a set value.

[0196] In some embodiments, the setting value may be indicated by the network device or agreed upon by a protocol.

[0197] In some other embodiments, when the number of bits of the second indication bit in the MAC CE is greater than the number of sub-configurations included in the activated CSI report configuration, the value of the second indication bit of the excess part may be randomly set, but the indication content of the second indication bit of the excess part is invalid. In this case, when the terminal receives such a MAC CE, the second indication bit of the excess part will be ignored.

[0198] In some embodiments, when the length of the MAC CE is variable, the length of the MAC CE is related to the activated CSI reporting configuration.

[0199] In some embodiments, when the length of the MAC CE is variable, the length of the MAC CE is related to the number of activated CSI reporting configurations.

[0200] In some embodiments, when the length of the MAC CE is variable, the length of the MAC CE is positively correlated with the number of activated CSI reporting configurations. That is, in this embodiment, the more the number of activated CSI reporting configurations is, the longer the length of the MAC CE is.

[0201] In some embodiments, when the length of the MAC CE is variable, the length of the MAC CE may be variable in steps of one octet.

[0202] like FIG. 3C to FIG. 3EAs shown, the first indication bit is located in the first octet of the MAC CE (e.g., oct2); the second indication bit is located in the second octet of the MAC CE (e.g., octn), where n may be greater than or equal to 3.

[0203] In some embodiments, the first octet and the second octet may be the same octet or different octets.

[0204] exist FIG. 3C to FIG. 3E Where Ni represents the second indication bit, and the value of i is 0 to 4. Figure 3A In , Sj represents the first indication bit, and the value range of j is 0 to 3.

[0205] Figure 3C The MAC CE shown has N octets. Figure 3D The MAC CE shown has 3 octets. Figure 3E The MAC CE shown has 4 octets.

[0206] In one embodiment, a second octet is used for sub-configuration activation of an activated first type reporting configuration.

[0207] In this implementation manner, the MAC CE has only the second indication bit for the sub-configuration of the first type of reporting configuration, that is, the number of the second indication bits is related to the number of the first type of reporting configurations activated by the MAC CE.

[0208] For example, an activated first-class report configuration corresponds to an octet. In the case where the MAC CE activates M first-class sub-configurations, there are M second indication bits contained in the octets in the MAC CE. The larger M is, the more bits of the second indication bit in the MAC CE, or the more octets the MAC CE contains, the longer the MAC CE is.

[0209] In other embodiments, a second octet corresponds to an activated CSI report configuration, and the CSI report configuration at this time may be the first type of report configuration and / or the second type of report configuration activated by the MAC CE. For example, if the MAC CE activates X CSI report configurations, then there are X octets in the MAC CE corresponding to the X activated CSI report configurations. In this case, a second octet corresponds to an activated CSI report configuration; when the activated CSI report configuration corresponding to the nth second octet is the second type of report configuration, the nth second octet has a first value, where n is a positive integer.

[0210] In some embodiments, n may be less than or equal to N, where N may be the number of CSI reporting configurations activated by the MAC CE.

[0211] In some embodiments, when one bit in the nth second octet is used to indicate a subconfiguration, the value of each bit in the nth second octet is "0" or the value of each bit in the nth second octet is "1".

[0212] In some embodiments, when a bit value of the nth second octet is used to indicate a combination of activation or deactivation of at least one sub-configuration, the first value of the nth second octet is a set value. When an octet corresponds to an activated CSI report configuration in the MACCE, the more the number of activated CSI report configurations, the larger the length of the MAC CE.

[0213] The octets corresponding to the CSI reporting configurations activated in the MAC CE are sorted from large to small according to the identifiers of the activated CSI reporting configurations, or, the octets corresponding to the CSI reporting configurations activated in the MAC CE are sorted from small to large according to the identifiers of the activated CSI reporting configurations, or, the octets corresponding to the CSI reporting configurations activated in the MAC CE are sorted from large to small according to the numbers of the first indication bits corresponding to the activated CSI reporting configurations, or, the octets corresponding to the CSI reporting configurations activated in the MAC CE are sorted from small to large according to the numbers of the first indication bits corresponding to the activated CSI reporting configurations, or, the octets corresponding to the CSI reporting configurations activated in the MAC CE are sorted from large to small according to the indexes of the activated CSI reporting configurations, and the octets corresponding to the CSI reporting configurations activated in the MAC CE are sorted from small to large according to the indexes of the activated CSI reporting configurations.

[0214] In one embodiment, since an octet corresponds to an activated CSI reporting configuration, the octet may indicate the activation or deactivation of a sub-configuration in a bitmap manner. In this case, if the second indication bit included in an octet is greater than the number of sub-configurations included in an activated CSI reporting configuration, the second indication bits of the excess part are invalid or ignored.

[0215] In some other implementations, the eight second indication bits included in an octet may also jointly indicate the activation status of multiple sub-configurations in the CSI report configuration.

[0216] In some embodiments, the length of the MAC CE is constant. Exemplarily, the length of the MAC CE is constant at 16 bits, that is, the MAC CE constantly includes two octets.

[0217] In this case, the MAC CE contains octets oct1 and oct2, and the reserved bits in oct1 and / or oct2 can be used as the second indication bit, and the second indication bit is used to indicate the activation or deactivation of the sub-configuration of the activated first type reporting configuration.

[0218] In some embodiments, if the MAC CE does not activate any first-type reporting configuration, the value of the reserved bit in oct1 and / or oct2 may be the first value, or remain in the reserved state.

[0219] In some embodiments, the second indication bits of the subconfiguration indicated by a second octet are numbered from high to low according to the identifier of the subconfiguration in the corresponding activated CSI reporting configuration, or the second indication bits of the subconfiguration indicated by a second octet are numbered from low to high according to the identifier of the subconfiguration in the corresponding activated CSI reporting configuration.

[0220] In some embodiments, the second indication bits of the subconfigurations indicated by a second octet are numbered in order from front to back in the activated CSI reporting configuration according to the subconfigurations, or the second indication bits of the subconfigurations indicated by a second octet are numbered in order from back to front in the CSI reporting configuration according to the subconfigurations.

[0221] like Figure 4 As shown, the embodiment of the present disclosure provides a CSI report configuration activation method, which is performed by a network device. The method may include:

[0222] S3101: The network device sends a MAC CE.

[0223] In some embodiments, the network device may include but is not limited to an access network device.

[0224] In some embodiments, the network device sends a MAC CE to the terminal.

[0225] In some embodiments, the MAC CE may be used to activate or deactivate a semi-persistent channel state information (SP-CSI) reporting configuration or an aperiodic CSI reporting configuration.

[0226] It is worth noting that the optional implementation of S3101 can be found in Figure 2 Related description of the corresponding embodiment.

[0227] In some embodiments, the MAC CE sent by the network device may be used for activation or deactivation of the first type of reporting configuration and / or the second type of reporting configuration.

[0228] In some embodiments, the MAC CE includes:

[0229] The first indication bit is used to indicate activation or deactivation of the CSI report configuration;

[0230] The second indication bit is used by the terminal to determine activation or deactivation of a sub-configuration in the activated first type of reporting configuration.

[0231] In some embodiments, the length of the MAC CE is variable, and the length of the MAC CE is related to the activated CSI reporting configuration.

[0232] In some embodiments, the first indication bit is located in the first octet of the MAC CE; and the second indication bit is located in the second octet of the MAC CE.

[0233] In some embodiments, a second octet is used for sub-configuration activation of an activated first type reporting configuration.

[0234] In some embodiments, a second octet corresponds to an activated CSI reporting configuration;

[0235] When the activated CSI report configuration corresponding to the nth second octet is the second type of report configuration, any bit value in the nth second octet is the first value, where n is a positive integer.

[0236] In some embodiments, n may be less than or equal to N, where N may be the number of CSI reporting configurations activated by the MAC CE.

[0237] In some embodiments, the length of the MAC CE is constant.

[0238] The second indication bit is used to indicate activation or deactivation of the sub-configuration of the activated first-type reporting configuration.

[0239] like Figure 5 As shown, the embodiment of the present disclosure provides a CSI report configuration activation method, which is executed by a terminal. The method may include:

[0240] S4101: The terminal receives MAC CE.

[0241] In some embodiments, the terminal receives a MAC CE sent by a network device.

[0242] In some embodiments, the MAC CE is used to activate or deactivate the CSI reporting configuration.

[0243] In some embodiments, the MAC CE sent by the network device may be used for activation or deactivation of the first type of reporting configuration and / or the second type of reporting configuration.

[0244] In some embodiments, the CSI reporting configuration includes a first type of reporting configuration and / or a second type of reporting configuration; the first type of reporting configuration includes one or more sub-configurations.

[0245] It is worth noting that the relevant description of the MAC CE in this embodiment, the relevant description of the first type of report configuration and / or the second type of report configuration can be found in Figure 2 The relevant parts of the corresponding embodiments will not be repeated here.

[0246] MAC CE includes:

[0247] The first indication bit is used to indicate activation or deactivation of the CSI report configuration;

[0248] The second indication bit is used by the terminal to determine activation or deactivation of a sub-configuration in the activated first type of reporting configuration.

[0249] In some embodiments, the length of the MAC CE is variable, and the length of the MAC CE is related to the activated CSI reporting configuration.

[0250] In some embodiments, the first indication bit is located in the first octet of the MAC CE; and the second indication bit is located in the second octet of the MAC CE.

[0251] In some embodiments, a second octet is used for sub-configuration activation of an activated first type reporting configuration.

[0252] In some embodiments, a second octet corresponds to an activated CSI reporting configuration;

[0253] When the activated CSI report configuration corresponding to the nth second octet is the second type of report configuration, the nth second octet has a first value, where n is a positive integer.

[0254] In some embodiments, specific examples of the first value can be found in Figure 2 Related description of the corresponding embodiment.

[0255] In some embodiments, n may be less than or equal to N, where N may be the number of CSI reporting configurations activated by the MAC CE.

[0256] In some embodiments, the length of the MAC CE is constant.

[0257] The second indication bit is used to indicate activation or deactivation of the sub-configuration of the activated first-type reporting configuration.

[0258] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc., which will not be repeated here.

[0259] In order to reduce the power consumption of network equipment, network equipment can dynamically reduce the number of spatial elements or transmission power corresponding to the transmission of downlink data based on the dynamic changes of transmission load, thereby reducing network energy consumption. Considering the dynamic adjustment of spatial elements or transmission power, the spatial pattern (SD) mode is adopted.

[0260] In some cases, sub-configurations are introduced in the CSI report configuration. A CSI report configuration may include one or more sub-configurations. At this time, the terminal can report CSI measurements with sub-configuration as the granularity. For the same CSI report config, L sub-configurations may be included, and each sub-configuration is associated with a specific spatial pattern (spatial pattern, SD) and / or multiple power consumption (power) standards.

[0261] To improve the reporting efficiency of the terminal and reduce the corresponding reporting overhead, for the configured L sub-configurations, the base station can activate / deactivate N of the sub-configurations through relevant signaling. For SP type CSI reporting, it can be activated / deactivated through MAC CE.

[0262] Under the condition that a CSI report config contains multiple reporting sub-configurations, the signaling indication activation / deactivation reporting sub-configuration is designed to improve the efficiency and accuracy of CSI measurement reporting and achieve consistent understanding between the terminal and the base station.

[0263] Under the condition that a CSI report configuration includes multiple reporting sub-configurations, the terminal can perform corresponding CSI measurement reporting according to the activated reporting sub-configuration.

[0264] In some embodiments, when the activated CSI report configuration corresponding to the nth second octet is the second type of report configuration, the terminal ignores the indication information of the nth second octet.

[0265] In this case, how to activate the CSI report configuration and / or the sub-configuration in the CSI report configuration is an issue that needs to be further resolved.

[0266] The embodiments of the present disclosure provide a method for activating a CSI reporting configuration including at least one sub-configuration.

[0267] When a CSI report config contains multiple reporting sub-configurations, the terminal receives the MAC CE and determines the activation status of the corresponding report config and / or sub-configuration. The activation status can be activated or deactivated.

[0268] Specific implementations include:

[0269] Mode 1: The activation or deactivation of a sub-configuration of a specific CSI report configuration is indicated through MAC CE, and the activation or deactivation of the sub-configuration is determined based on each CSI report configuration.

[0270] The MAC CE indicates the state of at least one CSI reportconfig based on a bitmap, where the state indicates activation or deactivation of the CSI report configuration.

[0271] The MAC CE indicates the activation status of the sub-configuration corresponding to the activated CSI report based on a bitmap.

[0272] The number of bits occupied by the MAC CE is determined based on the total number of activated report configs. For a legacy CSI report config, the corresponding sub-configuration indication value is 0.

[0273] The number of bits occupied by the MAC CE is determined based on the activated enhanced CSI report configuration. This enhanced CSI report configuration may include at least one sub-configuration. For the traditional CSI report configuration, the indication bit of the sub-configuration is not introduced.

[0274] In this case, the size of the MAC CE is variable, that is, the length of the MAC CE is a variable length, which can be understood as the length of the MAC CE.

[0275] Mode 2: For the activation status of a sub-configuration of a specific report config, and the indication signaling corresponding to the sub-configuration is applied to multiple sub-configurations.

[0276] The MAC CE indicates the activation status of at least one CSI report config based on a bitmap.

[0277] The MAC CE indicates the activation status of the sub-configuration corresponding to the activated enhanced CSI reporting configuration based on a bitmap.

[0278] For the base station, under the condition that a CSI report config contains multiple reporting sub-configurations, the base station sends a MAC CE to indicate the activation status of the corresponding report config and / or sub-configuration.

[0279] Mode 1: The activation or deactivation of a sub-configuration of a specific CSI report configuration is indicated through MAC CE, and the activation or deactivation of the sub-configuration is determined based on each CSI report configuration.

[0280] The MAC CE indicates the state of at least one CSI reportconfig based on a bitmap, where the state indicates activation or deactivation of the CSI report configuration.

[0281] The MAC CE indicates the activation status of the sub-configuration corresponding to the activated CSI report based on a bitmap.

[0282] The number of bits occupied by the MAC CE is determined based on the total number of activated report configs. For a legacy CSI report config, the corresponding sub-configuration indication value is 0.

[0283] The number of bits occupied by the MAC CE is determined based on the activated enhanced CSI report configuration. This enhanced CSI report configuration may include at least one sub-configuration. For the traditional CSI report configuration, the indication bit of the sub-configuration is not introduced.

[0284] In this case, the size of the MAC CE is variable, that is, the length of the MAC CE is a variable length, which can be understood as the length of the MAC CE.

[0285] Mode 2: For the activation status of a sub-configuration of a specific report config, and the indication signaling corresponding to the sub-configuration is applied to multiple sub-configurations.

[0286] The MAC CE indicates the activation status of at least one CSI report config based on a bitmap;

[0287] The MAC CE indicates the activation status of the sub-configuration corresponding to the activated enhanced CSI reporting configuration based on a bitmap.

[0288] The following will describe the specific implementation of the present invention from the perspective of the terminal:

[0289] The terminal is a terminal that supports NES features. To support measurement reports of multiple SDs (spatial patterns) and / or multiple power standards, NES supports sub-CSI reports that define multiple sub-configurations for the same CSI report config. Compared with one CSI report config corresponding to one CSI report, one CSI report config of NES corresponds to multiple sub-configurations, and each sub-configuration corresponds to one sub-CSI measurement report, which can effectively improve the performance of dynamic CSI measurement reports.

[0290] It is worth noting that the enhanced CSI report configuration under NES refers to a CSI report configuration that contains at least one sub-configuration. The legacy CSI report configuration does not contain the corresponding sub-configuration.

[0291] The embodiment of the present invention will describe the specific implementation methods for the indication signaling of sub-configuration under different reporting types, including:

[0292] Implementation method 1: design a new MAC CE, add a corresponding field, and indicate the activation status of the corresponding sub-configuration.

[0293] like Figure 3C As shown, the corresponding N0, ..., N7 in an Oct is applied to the corresponding activated CSIreport config indicated by S0, S1, ..., S3, the proportion of MAC CE is variable, and the value of n is a positive integer less than or equal to N.

[0294] Method 1-1: The number of bits occupied by the MAC CE is determined based on the total number of activated report configs.

[0295] Example scenarios such as Figure 3E As shown, if the report config corresponding to S0 and S1 is activated, and the CSIreportconfig corresponding to S1 is the legacy CSI report configuration, and the CSI report configuration corresponding to S0 is the enhanced CSI report configuration, then the corresponding MAC CE accounts for 32 bits. N0 to N7 of Oct 4 correspond to the CSI report configuration of S1, and the N0 to N7 indication bit value of Oct 4 is 0.

[0296] Method 1-2: The number of bits occupied by MAC CE is determined based on the total number of activated report configs. The exemplary scenario is as follows: Figure 3D As shown, if the CSI reporting configurations corresponding to S0 and S1 are activated, and the CSI reporting configuration corresponding to S1 is the legacy CSI reporting configuration, and the CSI reporting configuration corresponding to S0 is the enhanced CSI reporting configuration, then the number of bits corresponding to MAC CE is equal to 24 bits. N0 to N7 of Oct3 correspond to the enhanced CSI reporting configuration of S0, and N0 to N7 of Oct 3 indicate the activation status of the sub-configuration of the enhanced CSI reporting configuration t corresponding to S0.

[0297] Implementation 2: Use MAC CE to indicate activation or deactivation of a sub-configuration. For example, re-farming an existing reserved bit. For example, "R" is used to indicate the activation status of the corresponding sub-configuration. The specific MAC CE structure can be as follows: Figure 3A and / or Figure 3B shown.

[0298] Ni is the activation status of the sub-configuration corresponding to at least one activated CSI report. The percentage of MACCE is always 16 bits. The information field Ni (i=0, 1, 2, ...) indicating the sub-configuration applies to the activated CSI report configuration. The CSI report configuration includes at least one enhanced CSI report configuration.

[0299] If the corresponding activated CSI report configuration is the legacy CSI report configuration, the terminal ignores the corresponding Ni field.

[0300] In this embodiment, corresponding indication signaling is designed for a scenario where the enhanced CSI report configuration and the legacy CSI report configuration coexist in the NES scenario to determine the activation status of the CSI report configuration.

[0301] Under the condition that a CSI report config contains multiple reporting sub-configurations, the terminal receives the MAC CE and determines the activation status of the corresponding report config and / or sub-configuration.

[0302] Under the condition that a CSI report config contains multiple reporting sub-configurations, the base station sends a MAC CE to indicate the activation status of the corresponding report config and / or sub-configuration.
