[0035] Embodiments of the present disclosure provide a method and apparatus for activating channel state information (CSI) report configuration, a communication device, a communication system, and a storage medium.
[0036] In a first aspect, an embodiment of the present disclosure provides a method for activating a channel state information (CSI) reporting configuration, wherein the method is performed by a terminal. The method includes:
[0037] The network device sends a media access control MAC control element CE to the terminal. The MAC CE is used to activate or deactivate a CSI reporting configuration. The CSI reporting configuration includes a first-type reporting configuration and / or a second-type reporting configuration. The first-type reporting configuration includes one or more sub-configurations.
[0038] In the above embodiment, the network device can activate different types of CSI reporting configurations by sending a MAC CE-based message to the terminal. When the activated CSI reporting configuration is the first type of reporting configuration, 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 conjunction 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 reporting 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 reporting configuration.
[0042] In the above embodiment, an indication bit indicating activation or deactivation of a sub-configuration is introduced into the MAC CE, thereby enabling activation or deactivation indication at a sub-configuration granularity.
[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 reporting configuration. In this way, on the one hand, the required CSI reporting configuration can be activated through the MAC CE, and the length of the MAC CE is related to the activated CSI reporting 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; and the second indication bit is located in the second octet of the MAC CE.
[0046] Based on the above solution, an example of MAC CE bit distribution is given, which has the characteristics of high effective utilization of MAC CE bits 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-type reporting configuration.

[0054] 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.
[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.
[0058] In the above embodiment, the length of the MAC CE may be constant, so that one or more unused bits in the MAC CE may be used to indicate activation or deactivation of a sub-configuration, thereby reusing the MAC CE in the related art to activate or deactivate the sub-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 reporting configuration, thereby reducing the measurement power consumption of the terminal and saving bit overhead.
[0062] In conjunction 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 reporting 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 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-type 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 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, the first value of the nth second octet is a set value.

[0133] FIG2 is an interactive diagram illustrating a method for activating a channel state information (CSI) report configuration according to an exemplary embodiment. As shown in FIG2 , an 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 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 any type of communication device. 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 reporting configuration, and is not used for activation or deactivation of the first type of reporting configuration.
[0142] The third type of MAC CE can be used to activate or deactivate the first type of reporting configuration, and can also be used to activate or deactivate the second type of reporting configuration.
[0143] In some embodiments, the MAC CE sent by the network device may be used to activate or deactivate 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 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 reporting configuration and performs reporting only when the reporting conditions are met. Reporting here means sending the measured CSI information to the network device.
[0148] In some embodiments, the CSI reporting configuration may include at least one of the following:
[0149] Time-frequency resource information of the measured reference signal;
[0150] Indication 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;
[0153] Indication 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, a network device may send one or more CSI reporting configurations. Different CSI reporting configurations may correspond to different CSI resource configurations. Multiple CSI reporting configurations may correspond to the same CSI resource configuration. A CSI reporting configuration may include a semi-static CSI reporting configuration, a dynamic CSI reporting configuration, and / or a periodic CSI reporting configuration. A dynamic CSI reporting configuration may also be referred to as an aperiodic CSI reporting configuration. Different CSI reporting 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 reporting configuration may be a legacy CSI reporting configuration.
[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 (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 transmit 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 an embodiment of the present disclosure, the MAC CE includes: a first indication bit for indicating activation or deactivation of a 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, the 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 may indicate the activation or deactivation of at least one subconfiguration within the first type of reporting configuration via a bitmap. Each bit in the bitmap corresponds to a subconfiguration, and different bits carry specific bit values to indicate the activation or deactivation of the subconfiguration 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 MAC CE.
[0176] In some embodiments, the second indicator bit may indicate the combined activation or deactivation status of one or more sub-configurations in a first-type reporting configuration by means of a joint indication. For example, a value of the plurality of second indicator bits may correspond to a combined activation or deactivation status of the sub-configurations in the first-type reporting configuration, with different values corresponding to different combined statuses.
[0177] In some embodiments, the header and payload of the MAC protocol data unit (PDU) in which the MAC CE is located. The header of the 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] The MAC CE shown in FIG. 1B 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 used to indicate 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] Octet 1 is also used to indicate the serving cell identifier and / or the BWP identifier. For example, two bits in Octet 1 are used to indicate the BWP identifier, and five bits in Octet 1 are used to indicate the cell identifier. The cell identifier is used to identify the cell that sent the MAC CE, or the cell in which the MAC CE is valid.
[0183] For example, if the reserved bits in both oct 1 and oct 2 can be used as the second indicator bit, the bit distribution of the MAC CE can be as shown in Figure 3A. In Figure 3A, Ni represents the second indicator bit, and the value of i ranges from 0 to 4. In Figure 3A, Sj represents the first indicator bit, and the value of j ranges from 0 to 3.
[0184] For example, the reserved bits in oct 2 can all be used as the second indicator bit, and the bit distribution of the MAC CE can be as shown in Figure 3B. In Figure 3A, Ni represents the second indicator bit, and the value of i ranges from 0 to 3. In Figure 3A, Sj represents the first indicator bit, and the value of j ranges from 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 reporting configuration may be sent via an RRC message. The RRC message may carry one or more Information Elements (IEs). Assuming that one IE configures one CSI reporting configuration, the position of a sub-configuration within the IE determines the context of the sub-configuration within multiple sub-configurations. Assuming that one IE configures multiple CSI reporting configurations, the position of a sub-configuration within the IE depends on both the position of the CSI reporting configuration within the IE and its own position within the CSI reporting configuration.
[0188] As shown in Figures 3A and 3B, the MAC CE may include more than two octets. In this case, the bits included in the octet of oct3 in 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 a 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 and may be used to indicate activation or deactivation of a sub-configuration.
[0192] In some embodiments, when the number of second indication bits in the MAC CE is greater than the number of sub-configurations included in the activated CSI reporting configuration, the excess second indication bits have a first value, exemplarily, "0".
[0193] When the activated CSI report configuration corresponding to the nth second octet is the second type 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, the 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 other embodiments, when the number of second indication bits in a MAC CE exceeds the number of sub-configurations included in the activated CSI reporting configuration, the values of the second indication bits in the excess portion may be randomly set, but the indication content of the second indication bits in the excess portion is invalid. In this case, when the terminal receives such a MAC CE, the second indication bits in the excess portion are 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 such embodiments, the greater the number of activated CSI reporting configurations, the longer the MAC CE length.
[0201] In some embodiments, when the length of the MAC CE is variable, the length of the MAC CE may be variable with a step of one octet.
[0202] As shown in Figures 3C to 3E, the first indication bit is located in the first octet (e.g., oct2) of the MAC CE; the second indication bit is located in the second octet (e.g., octn) of the MAC CE, 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] In FIG3C to FIG3E , Ni represents the second indicator bit, and the value of i ranges from 0 to 4. In FIG3A , Sj represents the first indicator bit, and the value of j ranges from 0 to 3.
[0205] The MAC CE shown in Figure 3C has N octets. The MAC CE shown in Figure 3D has 3 octets. The MAC CE shown in Figure 3E 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 embodiment, the MAC CE only has 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, if an activated first-class reporting configuration corresponds to one octet, then when the MAC CE activates M first-class sub-configurations, the MAC CE contains M second indication bits in each octet. The larger M is, the more second indication bits there are 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 reporting configuration, in which case the CSI reporting configuration may be a first-category reporting configuration and / or a second-category reporting configuration activated by the MAC CE. For example, if the MAC CE activates X CSI reporting configurations, then the MAC CE contains X octets corresponding to these X activated CSI reporting configurations. In this case, a second octet corresponds to an activated CSI reporting configuration; when the activated CSI reporting configuration corresponding to the nth second octet is the second-category reporting configuration, then the nth second octet has the 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 in a MAC CE corresponds to an activated CSI reporting configuration, the greater the number of activated CSI reporting configurations, the greater 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 identifier 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 identifier 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 number of the first indication bit 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 number of the first indication bit 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 index 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 index 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 subconfiguration using a bitmap. In this case, if the number of second indicator bits in an octet is greater than the number of subconfigurations in an activated CSI reporting configuration, the excess second indicator bits 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 reporting configuration.
[0216] In some embodiments, the length of the MAC CE is constant. For example, the length of the MAC CE is constant at 16 bits, that is, the MAC CE always 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 numbering of the second indication bits of the subconfiguration indicated by a second octet is sorted from high to low according to the identifier of the subconfiguration in the corresponding activated CSI reporting configuration, or the numbering of the second indication bits of the subconfiguration indicated by a second octet is sorted from low to high according to the identifier of the subconfiguration in the corresponding activated CSI reporting configuration.
[0220] In some embodiments, the numbers of the second indication bits of the subconfigurations indicated by a second octet are sorted from front to back in the activated CSI reporting configuration according to the subconfigurations, or the numbers of the second indication bits of the subconfigurations indicated by a second octet are sorted from back to front in the CSI reporting configuration according to the subconfigurations.
[0221] As shown in FIG4 , an embodiment of the present disclosure provides a method for activating a CSI report configuration, 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: for optional implementation of S3101, please refer to the relevant description of the corresponding embodiment in Figure 2.
[0227] In some embodiments, the MAC CE sent by the network device may be used to activate or deactivate 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 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, the value of any bit 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] As shown in FIG5 , an embodiment of the present disclosure provides a method for activating a CSI report configuration, 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 to activate or deactivate 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 descriptions of the MAC CE, the first type of reporting configuration and / or the second type of reporting configuration in this embodiment can be found in the relevant parts of the embodiment corresponding to FIG2 , and will not be repeated here.
[0246] MAC CE includes:
[0247] The first indication bit is used to indicate activation or deactivation of the CSI reporting 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 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 reporting 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 the relevant description of the embodiment corresponding to FIG2 .
[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. embodiments, which will not be repeated here.
[0259] To reduce network device power consumption, network devices can dynamically reduce the number of spatial elements or transmission power corresponding to downlink data transmission based on dynamic changes in transmission load, thereby reducing network energy consumption. This dynamic adjustment of spatial elements or transmission power is considered in the spatial adaptation (SD) model.
[0260] In some cases, sub-configurations are introduced in the CSI reporting configuration. A CSI reporting configuration may include one or more sub-configurations. In this case, the terminal can report CSI measurements at the granularity of the sub-configuration. For the same CSI reporting configuration, L sub-configurations may be included, each of which is associated with a specific spatial pattern (SD) and / or multiple power consumption standards.
[0261] To improve terminal reporting efficiency and reduce corresponding reporting overhead, the base station can activate / deactivate N of the configured L sub-configurations through relevant signaling. For SP-type CSI reporting, activation / deactivation can be performed through MAC CE.
[0262] When a CSI report configuration contains multiple reporting sub-configurations, signaling is designed to indicate activation / deactivation of the reporting sub-configuration to improve the efficiency and accuracy of CSI measurement reporting and achieve consistent understanding between the terminal and the base station.
[0263] When a CSI report configuration includes multiple reporting sub-configurations, the terminal may 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 reporting configuration, the terminal ignores the indication information of the nth second octet.
[0265] In this case, how to activate the CSI reporting configuration and / or the sub-configuration in the CSI reporting configuration is an issue that needs to be further addressed.
[0266] 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 divided into activation or deactivation.
[0268] Specific implementations include:
[0269] Method 1: The activation or deactivation of a sub-configuration of a specific CSI report configuration is indicated through the 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 status of at least one CSI report configuration based on a bitmap, which indicates whether the CSI report configuration is activated or deactivated.
[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 configurations. For the legacy CSI report configuration, the corresponding sub-configuration indicator value is 0.
[0273] The number of bits occupied by the MAC CE is determined based on the activated enhanced CSI reporting configuration. This enhanced CSI reporting configuration may include at least one sub-configuration. For traditional CSI reporting configurations, no sub-configuration indication bits are introduced.
[0274] In this case, the size of the MAC CE is variable. That is, the length of the MAC CE is variable. This size 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 configuration, 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] Method 1: The activation or deactivation of a sub-configuration of a specific CSI report configuration is indicated through the 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 status of at least one CSI report configuration based on a bitmap, which indicates whether the CSI report configuration is activated or deactivated.
[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 configurations. For the legacy CSI report configuration, the corresponding sub-configuration indicator value is 0.
[0283] The number of bits occupied by the MAC CE is determined based on the activated enhanced CSI reporting configuration. This enhanced CSI reporting configuration may include at least one sub-configuration. For traditional CSI reporting configurations, no sub-configuration indication bits are introduced.
[0284] In this case, the size of the MAC CE is variable. That is, the length of the MAC CE is variable. This size 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 configuration, 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 supports the NES feature. To support measurement reporting for multiple SDs (spatial patterns) and / or multiple power standards, the NES supports sub-CSI reporting for multiple sub-configurations defined for the same CSI report configuration. While one CSI report configuration corresponds to one CSI report, the NES supports multiple sub-configurations for one CSI report configuration, each corresponding to a sub-CSI measurement report. This effectively improves dynamic CSI measurement reporting performance.
[0290] It is worth noting that an enhanced CSI report configuration under NES refers to a CSI report configuration that includes at least one sub-configuration. The legacy CSI report configuration does not include the corresponding sub-configuration.
[0291] The embodiment of the present invention will describe the specific implementation methods of the sub-configuration indication signaling 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] As shown in FIG3C , the corresponding N0, ..., N7 in an Oct is applied to the corresponding activated CSI report 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] In the exemplary scenario shown in Figure 3E , if the report configs corresponding to S0 and S1 are activated, and the CSI report config corresponding to S1 is the legacy CSI report config, and the CSI report config corresponding to S0 is the enhanced CSI report config, the corresponding MAC CE percentage is 32 bits. N0-N7 of Oct 4 correspond to the CSI report configuration of S1, and the N0-N7 indicator bit value of Oct 4 is 0.
[0296] Method 1-2: The number of bits occupied by the MAC CE is determined based on the total number of activated report configurations. For an exemplary scenario, as shown in Figure 3D , 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, the number of bits occupied by the corresponding MAC CE is 24 bits. N0-N7 of Oct 3 correspond to the enhanced CSI reporting configuration of S0, and N0-N7 of Oct 3 indicate the activation status of the subconfiguration of the enhanced CSI reporting configuration corresponding to S0.
[0297] Implementation 2: Using a MAC CE to indicate activation or deactivation of a sub-configuration. For example, refarming an existing reserved bit, such as "R," indicates activation of the corresponding sub-configuration. The specific MAC CE structure may be as shown in FIG3A and / or FIG3B.
[0298] Ni represents the activation status of the sub-configuration corresponding to at least one activated CSI report. The MAC CE bit percentage 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] This embodiment designs corresponding indication signaling for the NES scenario where the enhanced CSI reporting configuration and the legacy CSI reporting configuration coexist to determine the activation status of the CSI reporting configuration.
[0301] 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.
[0302] When 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.
