[0153] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0154] As shown in FIG. 1A , a communication system 100 includes a terminal 101 and a network device 102 .

[0155] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0156] In some embodiments, the network device 102 may include but is not limited to at least one of an access network device 102 - 1 and a core network device 102 - 2 .

[0157] In some embodiments, the access network device 102-1 is, for example, a node or device that accesses a terminal to a wireless network.

[0158] In some embodiments, the access network device 102-1 can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0159] In some embodiments, the core network device 102-2 may be a device including one or more network elements, or may be multiple devices or a group of devices. The network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0160] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0161] In some embodiments, in some embodiments, the terminal 101 is connected to the core network device 102-2 through the access network device 102-1.

[0162] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0163] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0164] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, systems utilizing other communication methods, and next-generation systems based on these. Furthermore, a combination of multiple systems (for example, a combination of LTE or LTE-A with 5G) may also be used.

[0165] In the disclosed embodiments, considering the dynamic adaptation of spatial elements or transmit power, Release 18 defines Channel State Information (CSI) reporting at a sub-configuration granularity. A single CSI report configuration may contain L sub-configurations, each associated with a specific spatial domain (SD) adaptation pattern and / or power domain (PD) adaptation pattern.

[0166] In some embodiments, at least one of the following adaptive methods may be included but is not limited to:

[0167] Type 1 SD (also referred to as Type 1 SD in subsequent embodiments): A Channel State Information-Reference Signal (CSI-RS) resource corresponding to Type 1 SD corresponds to multiple SD patterns. Referring to Figure 1B , in Type 1 SD mode, port #x is in the disabled state in SD pattern #2.

[0168] Type 2 SD (also referred to as the second type of SD in subsequent embodiments): A CSI-RS resource corresponding to a type 2 SD corresponds to an SD pattern, but the same antenna port is mapped to different numbers of antenna elements, and different SD patterns correspond to the same number of antenna ports. As shown in Figure 1C, in the type 2 SD mode, when port #x is mapped to different antenna elements, port #x remains active.

[0169] PD: A CSI-RS resource can correspond to different power control offsets (powercontroloffset). Powercontroloffset is used to indicate the power offset between the Physical Downlink Shared Channel (PDSCH) Resource Element (RE) and the Non-Zero Power Channel State Information-Reference Signal (NZP CSI-RS) RE.

[0170] In some embodiments, when the CSI reporting configuration includes multiple sub-configurations, the configuration manner of the sub-configurations may correspond to any of the following adaptive manners:

[0171] The first type is type 1 SD only adaptation;

[0172] The second type is type 2 SD only adaptive;

[0173] The third type is PD only adaptation;

[0174] The fourth type is joint adaptation between type 1 SD and PD;

[0175] The fifth type is joint adaptation between type 2 SD and PD.

[0176] Considering that in type 1 SD, different SD patterns correspond to different numbers of antenna ports, that is, the number of antenna ports is variable, but in type 2 SD, different SD patterns correspond to the same number of antenna ports, that is, the number of antenna ports remains unchanged, therefore, joint adaptation between type 1 SD and type 2 SD is not supported.

[0177] To reduce network device energy consumption, for example but not limited to in Network Energy Saving (NES) scenarios, network device 102 can dynamically change the number of spatial elements or transmission power, and accordingly, the sub-configuration configuration method can be changed. To improve the availability of controlling network energy consumption and avoid the number of antenna ports configured on a network device exceeding the terminal capabilities, the present disclosure provides the following port number determination method, apparatus, and storage medium.

[0178] FIG2A is an interactive diagram illustrating a method for determining the number of ports according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a method for determining the number of ports, and the method includes:

[0179] In step S2100 , the terminal 101 sends terminal capability information.

[0180] In some embodiments, the terminal capability information is used to indicate the antenna port capabilities supported by the terminal 101 .

[0181] Exemplarily, the terminal capability information is used to indicate whether the terminal 101 supports dynamic changes in the number of antenna ports.

[0182] Exemplarily, the terminal capability information is used to indicate the maximum number of antenna ports supported by the terminal 101.

[0183] Exemplarily, the terminal capability information is used to indicate whether the terminal 101 supports dynamic changes in the number of antenna ports, and the maximum number of antenna ports supported by the terminal 101.

[0184] In some embodiments, the terminal 101 may report the terminal capability information to the network device 102 via a Radio Resource Control (RRC) message.

[0185] In some embodiments, the network device 102 receives the terminal capability information.

[0186] In step S2101 , the network device 102 determines X.

[0187] Here, X is associated with the sub-configurations configured or activated within the CSI reporting configuration. It is understood that X may refer to the number of sub-configurations configured within the CSI reporting configuration, or the number of sub-configurations activated within the CSI reporting configuration.

[0188] In some embodiments, network device 102 may determine X based on the type of CSI-RS resource and / or the type of CSI report.

[0189] In one example, when the network device 102 determines X based on the type of the CSI-RS resource, it may include any of the following:

[0190] If the CSI-RS resource belongs to a periodic (P) resource, X is determined to be equal to the total number of sub-configurations configured in the CSI report configuration.

[0191] For example, a total of L sub-configurations are configured in the CSI report configuration, and for PCSI resources, X=L.

[0192] If the CSI-RS resource is a semi-persistent (SP) resource, X is determined to be equal to the total number of sub-configurations configured in the CSI reporting configuration, or X is determined to be equal to the number of corresponding activated sub-configurations in the CSI reporting configuration.

[0193] For example, a total of L sub-configurations are configured in the CSI report configuration, and for SP CSI resources, X=L, where L is a positive integer.

[0194] For another example, a total of L sub-configurations are configured in the CSI report configuration, the number of sub-configurations in the activated state is N, N is less than or equal to L, and for SP CSI resources, X=N, where N and L are positive integers.

[0195] If the CSI-RS resource belongs to an aperiodic (AP) resource, X is determined to be equal to the number of sub-configurations in the CSI report configuration that are in the corresponding activated state.

[0196] For another example, a total of L sub-configurations are configured in the CSI report configuration, the number of sub-configurations in the activated state is N, N is less than or equal to L, and for AP CSI resources, X=N, where N and L are positive integers.

[0197] In one example, when the network device 102 determines X based on the type of the CSI report, it may include any of the following:

[0198] If the CSI report belongs to a PCSI report, X is determined to be equal to the total number of subconfigurations configured in the CSI report configuration.

[0199] For example, a total of L sub-configurations are configured in the CSI report configuration. For PCS report, X=L.

[0200] If the CSI report belongs to an SP CSI report, X is determined to be equal to the total number of subconfigurations configured in the CSI report configuration, or X is determined to be equal to the number of corresponding subconfigurations in the CSI report configuration that are in an activated state.

[0201] For example, a total of L sub-configurations are configured in the CSI report configuration, and for SP CSI reporting, X=L, where L is a positive integer.

[0202] For another example, a total of L sub-configurations are configured in the CSI report configuration, the number of sub-configurations in the activated state is N, N is less than or equal to L, and for SP CSI reporting, X=N, where N and L are positive integers.

[0203] If the CSI report belongs to an AP CSI report, X is determined to be equal to the number of corresponding sub-configurations in the CSI report configuration that are in an activated state.

[0204] For another example, a total of L sub-configurations are configured in the CSI report configuration, the number of sub-configurations in the activated state is N, N is less than or equal to L, and for AP CSI reporting, X=N, where N and L are positive integers.

[0205] In one example, the network device 102 may determine X based on the type of CSI-RS resource and / or the type of CSI report, which may include but is not limited to any of the following:

[0206] For PCSI-RS resources and / or PCCSI reports, X=L;

[0207] For SP CSI-RS resources and / or SP CSI reports, X=L or X=N;

[0208] For AP CSI-RS resources and / or AP CSI reports, X=N;

[0209] For other types of CSI-RS resources and / or other types of combinations of PC CSI reports, for example, SP CSI-RS resources and AP CSI reports, X=N.

[0210] The above description is merely an example, and all solutions for determining the value of X should fall within the scope of protection of this disclosure.

[0211] In step S2102 , the network device 102 determines the number of antenna ports.

[0212] In some embodiments, the number of antenna ports is the number of antenna ports corresponding to one CSI-RS resource in one CSI reporting configuration.

[0213] In some embodiments, the number of antenna ports determined by the network device 102 does not exceed the terminal capability.

[0214] In some embodiments, the CSI reporting configuration includes multiple sub-configurations.

[0215] In some embodiments, the CSI-RS resource is associated with M sub-configurations among X sub-configurations included in the CSI reporting configuration, where X and M are positive integers and M is less than or equal to X.

[0216] Here, X is associated with the sub-configurations configured or activated within the CSI reporting configuration. It is understood that X may refer to the number of sub-configurations configured within the CSI reporting configuration, or the number of sub-configurations activated within the CSI reporting configuration.

[0217] Wherein, M is the number of sub-configurations associated with the CSI-RS resource, and the sub-configuration associated with the CSI-RS resource belongs to X sub-configurations.

[0218] In some embodiments, the network device 102 may first determine the value of X based on step S2101 and then determine the number of antenna ports.

[0219] In some embodiments, the network device 102 determines the number of antenna ports corresponding to a CSI reporting configuration for a CSI-RS resource as follows:

[0220] In the first manner, when the sub-configuration in the CSI report configuration corresponds to SD adaptation and the corresponding SD type is a first type SD (type 1 SD), the number of antenna ports is determined to be equal to the first value.

[0221] Any sub-configuration in a CSI reporting configuration is associated with all resources within a set. In the disclosed embodiment, a set refers to a CSI-RS resource set, and all resources within a set refer to all CSI-RS resources within the CSI-RS resource set. A CSI-RS resource within the set is associated with all sub-configurations, and all CSI-RS resources within the set have the same number of antenna ports.

[0222] For example, the first value may be M P s The sum of the values ​​and the maximum value in P, P s is the number of antenna ports corresponding to the sub-configuration s among the M sub-configurations, and P is the default number of antenna ports corresponding to the CSI-RS resources.

[0223] For example, P s is the number of antenna ports corresponding to the sub-configuration s among the M sub-configurations, and P is the default number of antenna ports corresponding to the CSI-RS resources.

[0224] The default number of antenna ports can be determined using any of the following methods:

[0225] After the network device 102 determines the default number of antenna ports, it configures it to the terminal 101 through the RRC parameter nrofport;

[0226] The network device 102 determines, based on a predefined method, such as a protocol agreed method, that the number of default antenna ports is equal to the maximum number of antenna ports corresponding to the CSI-RS resources. For example, the number of default antenna ports is 32.

[0227] In the second manner, when the sub-configuration in the CSI report configuration corresponds to SD adaptation and the corresponding SD type is type 2 SD, the network device 102 may determine that the number of antenna ports is equal to the product of M and P.

[0228] Where P is the default number of antenna ports corresponding to the CSI-RS resource. The method for determining the default number of antenna ports has been described in the above embodiment and will not be repeated here. M is the number of subconfigurations associated with the CSI-RS resource. The subconfiguration associated with the CSI-RS resource belongs to X subconfigurations.

[0229] Any sub-configuration in a CSI reporting configuration can be associated with some resources within a set. In the embodiment of the present disclosure, the set refers to a CSI-RS resource set, and some resources within the set refer to some CSI-RS resources within the CSI-RS resource set. A CSI-RS resource within the set is associated with only one sub-configuration (in the embodiment of the present disclosure, a single CSI-RS resource can only be associated with one SD), and all CSI-RS resources within the set have the same number of antenna ports.

[0230] Exemplarily, the number of antenna ports = M × P, where P is the default number of antenna ports corresponding to the CSI-RS resource. M is the number of subconfigurations associated with the CSI-RS resource, and the subconfiguration associated with the CSI-RS resource belongs to X subconfigurations.

[0231] In a third approach, when a subconfiguration in the CSI reporting configuration corresponds to PD adaptation, network device 102 may determine that the number of antenna ports is equal to the product of M and P. P is the default number of antenna ports corresponding to the CSI-RS resource. The method for determining the default number of antenna ports has been described in the above embodiment and will not be repeated here. M is the number of subconfigurations associated with the CSI-RS resource, and the subconfiguration associated with the CSI-RS resource belongs to X subconfigurations.

[0232] Any subconfiguration in a CSI reporting configuration is associated with all resources within a set. In the disclosed embodiment, a set refers to a CSI-RS resource set, and a portion of resources within a set refers to a portion of CSI-RS resources within the CSI-RS resource set. A CSI-RS resource within the set is associated with all subconfigurations, each subconfiguration corresponds to an offset value, and all resources within the set have the same number of antenna ports.

[0233] Exemplarily, the number of antenna ports = M × P, where P is the default number of antenna ports corresponding to the CSI-RS resource. M is the number of subconfigurations associated with the CSI-RS resource, and the subconfiguration associated with the CSI-RS resource belongs to X subconfigurations.

[0234] The fourth method is that when the sub-configuration in the CSI report configuration corresponds to the joint adaptation between SD and PD, specifically, corresponds to the joint adaptation between the first type of SD (type 1 SD) and PD, it can be determined that the number of antenna ports is equal to the first value.

[0235] One CSI-RS resource corresponding to the first type of SD corresponds to multiple SD patterns.

[0236] The first type of joint adaptation between SD and PD may mean that the same CSI-RS resource may correspond to multiple SD patterns, and different sub-configurations under the same SD pattern may correspond to different PD offsets.

[0237] For example, as shown in Figure 2B, resource #1 corresponds to SD pattern #1 and SD pattern #2, where SD pattern #1 corresponds to 32 antenna ports and SD pattern #2 corresponds to 16 antenna ports. In addition, under SD pattern #1, sub-configuration #1 to sub-configuration #3 correspond to different PD offsets.

[0238] For example, the first value may be M P s The sum of the values ​​and the maximum value in P, P sis the number of antenna ports corresponding to the sub-configuration s in the M sub-configurations, and P is the default number of antenna ports corresponding to the CSI-RS resources. That is, a minimum value of the first value may be limited, and the minimum value may be P.

[0239] For example, P s is the number of antenna ports corresponding to the sub-configuration s among the M sub-configurations, and P is the default number of antenna ports corresponding to the CSI-RS resources.

[0240] For example, the first value may be M P s The sum of P s is the number of antenna ports corresponding to the sub-configuration s in the M sub-configurations. That is, the minimum value of the first value may not be limited.

[0241] For example, Among them, P s is the number of antenna ports corresponding to sub-configuration s among the M sub-configurations.

[0242] For example, the first value may be L P s The sum of P s is the number of antenna ports corresponding to the sub-configuration s in the M sub-configurations. Similarly, the minimum value of the first value may not be limited.

[0243] For example, Among them, P s is the number of antenna ports corresponding to subconfiguration s in the M subconfigurations. L is the total number of subconfigurations configured in the CSI reporting configuration.

[0244] Alternatively, in a fourth manner, when the sub-configuration in the CSI report configuration corresponds to the joint adaptation between SD and PD, specifically, corresponds to the joint adaptation between the first type of SD (type 1 SD) and PD, it can be determined that the number of antenna ports is equal to the product of M and P.

[0245] One CSI-RS resource corresponding to the first type of SD corresponds to multiple SD patterns.

[0246] The first type of joint adaptation between SD and PD may mean that the same CSI-RS resource may correspond to multiple SD patterns, and different sub-configurations under the same SD pattern may correspond to different PD offsets, as shown in FIG2B .

[0247] In this case, the number of antenna ports can be equal to the product of M and P, that is, the number of antenna ports = M × P. P is the default number of antenna ports corresponding to the CSI-RS resource. M is the number of subconfigurations associated with the CSI-RS resource, and the subconfiguration associated with the CSI-RS resource belongs to X subconfigurations.

[0248] It should be noted that, in the fourth manner, the network device 102 needs to perform joint adaptive configuration restriction to ensure that the number of antenna ports is equal to the product of M and P.

[0249] In one example, the number of antenna ports corresponding to the M sub-configurations configured by the network device 102 is equal to P. That is, the number of antenna ports corresponding to each of the M sub-configurations configured by the network device 102 is P. P is the default number of antenna ports corresponding to the CSI-RS resources.

[0250] For the terminal 101, when the CSI-RS resources correspond to the joint adaptation between the first type of SD and PD, it can be determined that the number of antenna ports corresponding to the M sub-configurations is equal to P.

[0251] In one example, if Ps is less than P, P s Where is the number of antenna ports corresponding to subconfiguration s among the M subconfigurations, and P is the default number of antenna ports corresponding to the CSI-RS resource, then for a type 1 SD image of the CSI-RS resource, network device 102 will not configure a PD pattern. For subconfigurations that do not have a PD pattern configured, the default PD offset can be set to 0. Alternatively, if subconfiguration s and subconfiguration m (s≠m) correspond to the same type 1 SD pattern, network device 102 will not configure different PD offsets for subconfiguration s and subconfiguration m.

[0252] Accordingly, terminal 101 does not expect the CSI-RS resources to be configured with a PD pattern under the first type SD pattern. For subconfigurations that do not have a PD pattern configured, the default PD offset can be 0. Alternatively, if subconfiguration s and subconfiguration m (s≠m) correspond to the same type 1 SD pattern, the terminal does not expect subconfiguration s and subconfiguration m to be configured with different PD offsets.

[0253] In one example, Pc is less than P, P c is the number of antenna ports corresponding to pattern c in different SD patterns, and P is the default number of antenna ports corresponding to the CSI-RS resource. Therefore, when the CSI-RS resource is in the SD pattern corresponding to Pc, the network device 102 will not configure multiple PD patterns.

[0254] Accordingly, at this time, the terminal 101 does not expect the CSI-RS resources to be configured with multiple PD patterns under the SD pattern corresponding to Pc.

[0255] In some embodiments, to reduce computational load and complexity of terminal 101, network device 102 may not configure joint adaptation between type 1 SD (type 1 SD) and PD. In other words, if joint adaptation between SD and PD is configured, only joint adaptation between type 2 SD (type 2 SD) and PD is configured.

[0256] Accordingly, for the terminal 101, the terminal 101 does not expect the CSI reporting configuration to be a CSI reporting configuration corresponding to the joint adaptation between the first type SD (type 1 SD) and PD.

[0257] In the fifth method, when the sub-configuration in the CSI report configuration corresponds to the joint adaptation between SD and PD, specifically, corresponds to the joint adaptation between the second type of SD (type 2 SD) and PD, it can be determined that the number of antenna ports is equal to the product of M and P.

[0258] Among them, one CSI-RS resource corresponding to the second type of SD corresponds to one SD pattern.

[0259] The second type of joint adaptation between SD and PD may mean that the same CSI-RS resource corresponds to one SD pattern, and different sub-configurations correspond to different PD offsets.

[0260] For example, as shown in Figure 2C, resource #1 corresponds to the same SD pattern, namely SD pattern #1. Resource #4 corresponds to the same SD pattern, namely SD pattern #2. SD pattern #1 and SD pattern #2 both correspond to the same number of antenna ports, 8. Different sub-configurations correspond to different PD offsets.

[0261] Exemplarily, at this time, the number of antenna ports = M × P, where P is the default number of antenna ports corresponding to the CSI-RS resource. M is the number of sub-configurations associated with the CSI-RS resource, and the sub-configuration associated with the CSI-RS resource belongs to X sub-configurations.

[0262] The above description is merely an example, and all solutions for determining the number of antenna ports by the network device 102 should fall within the scope of protection of this disclosure.

[0263] In step S2103 , the network device 102 performs joint adaptive configuration restriction.

[0264] In some embodiments, when the sub-configuration in the CSI report configuration corresponds to joint adaptation between SD and PD, specifically, joint adaptation between a first type SD (type 1 SD) and PD, network device 102 may enforce the joint adaptation configuration restriction. The specific implementation has been described in the fourth approach in step S2102 and will not be repeated here.

[0265] In some embodiments, the network device 102 may not configure joint adaptation between type 1 SD and PD. That is, if joint adaptation between SD and PD is configured, only joint adaptation between type 2 SD and PD is configured.

[0266] In step S2104 , the network device 102 sends a CSI report configuration to the terminal 101 .

[0267] In some embodiments, the number of antenna ports corresponding to the CSI report configuration of the CSI-RS resources configured by the network device 102 should not exceed the terminal capability.

[0268] In some embodiments, terminal 101 receives the CSI reporting configuration.

[0269] In some embodiments, after receiving the CSI report configuration, the terminal 101 can determine the reference resource corresponding to the CSI report, receive the CSI-RS based on the reference resource, measure the CSI-RS to generate one or more CSIs, and send a CSI report, wherein the CSI report includes at least one of the generated CSIs.

[0270] Exemplarily, if the terminal 101 does not receive all resources associated with all sub-configurations configured by the CSI reporting configuration no later than the time slot corresponding to the reference resource, the terminal discards the CSI corresponding to the CSI reporting configuration.

[0271] Exemplarily, if the terminal 101 does not receive any resource associated with all sub-configurations configured by the CSI reporting configuration no later than the time slot corresponding to the reference resource, the terminal discards the CSI corresponding to the CSI reporting configuration.

[0272] Exemplarily, if the terminal 101 does not receive all resources associated with all sub-configurations activated by the CSI reporting configuration no later than the time slot corresponding to the reference resource, the terminal discards the CSI corresponding to the CSI reporting configuration.

[0273] Exemplarily, if the terminal 101 does not receive any resource associated with all sub-configurations activated by the CSI reporting configuration no later than the time slot corresponding to the reference resource, the terminal discards the CSI corresponding to the CSI reporting configuration.

[0274] In step S2105 , the terminal 101 determines X.

[0275] In some embodiments, where X is associated with a configured or activated subconfiguration within a CSI reporting configuration, it is understood that X may refer to the number of configured subconfigurations within a CSI reporting configuration, or the number of activated subconfigurations within a CSI reporting configuration.

[0276] In some embodiments, terminal 101 may determine X based on the type of CSI-RS resource and / or the type of CSI report.

[0277] In some embodiments, the terminal 101 determines X in a similar manner to the network device 102 . For details, please refer to the implementation of step S2101 , which will not be repeated here.

[0278] In step S2106 , the terminal 101 determines the number of antenna ports.

[0279] In some embodiments, the number of antenna ports is the number of antenna ports corresponding to one CSI-RS resource in one CSI reporting configuration.

[0280] In some embodiments, the number of antenna ports determined by terminal 101 does not exceed the terminal capability.

[0281] In some embodiments, the CSI reporting configuration includes multiple sub-configurations.

[0282] In some embodiments, the CSI-RS resource is associated with M sub-configurations among X sub-configurations included in the CSI reporting configuration, where X and M are positive integers and M is less than or equal to X.

[0283] In some embodiments, the terminal 101 may first determine the value of X based on step S2104 and then determine the number of antenna ports.

[0284] In some embodiments, the terminal 101 determines the number of antenna ports as follows:

[0285] In the first manner, when the sub-configuration in the CSI report configuration corresponds to SD adaptation and the corresponding SD type is a first type SD (type 1 SD), the number of antenna ports is determined to be equal to the first value.

[0286] For example, the first value may be M P s The sum of the values ​​and the maximum value in P, P s is the number of antenna ports corresponding to the sub-configuration s among the M sub-configurations, and P is the default number of antenna ports corresponding to the CSI-RS resources.

[0287] For example, P s is the number of antenna ports corresponding to the sub-configuration s among the M sub-configurations, and P is the default number of antenna ports corresponding to the CSI-RS resources.

[0288] The default number of antenna ports can be determined using any of the following methods:

[0289] The terminal 101 determines the default number of antenna ports based on the RRC parameters (e.g., nrofport) sent by the network device 102;

[0290] The terminal 101 determines, based on a predefined manner, such as a protocol agreement, that the number of default antenna ports is equal to the maximum number of antenna ports corresponding to the CSI-RS resources. For example, the number of default antenna ports is 32.

[0291] In the second approach, when the subconfiguration in the CSI report configuration corresponds to SD adaptation and the corresponding SD type is type 2 SD, terminal 101 may determine that the number of antenna ports is equal to the product of M and P. For example, the number of antenna ports = M × P, where P is the default number of antenna ports corresponding to the CSI-RS resource. M is the number of subconfigurations associated with the CSI-RS resource, and the subconfiguration associated with the CSI-RS resource belongs to X subconfigurations.

[0292] In a third manner, when the sub-configuration in the CSI report configuration corresponds to PD adaptation, the terminal 101 may determine that the number of antenna ports is equal to the product of M and P.

[0293] Exemplarily, the number of antenna ports = M × P, where P is the default number of antenna ports corresponding to the CSI-RS resource. M is the number of subconfigurations associated with the CSI-RS resource, and the subconfiguration associated with the CSI-RS resource belongs to X subconfigurations.

[0294] The fourth method is that when the sub-configuration in the CSI report configuration corresponds to the joint adaptation between SD and PD, specifically, corresponds to the joint adaptation between the first type of SD (type 1 SD) and PD, the terminal 101 can determine that the number of antenna ports is equal to the first value.

[0295] One CSI-RS resource corresponding to the first type of SD corresponds to multiple SD patterns.

[0296] The first type of joint adaptation between SD and PD may mean that the same CSI-RS resource may correspond to multiple SD patterns, and different sub-configurations under the same SD pattern may correspond to different PD offsets.

[0297] For example, the first value may be M P s The sum of the values ​​and the maximum value in P, P s is the number of antenna ports corresponding to the sub-configuration s in the M sub-configurations, and P is the default number of antenna ports corresponding to the CSI-RS resources. That is, a minimum value of the first value may be limited, and the minimum value may be P.

[0298] For example, P s is the number of antenna ports corresponding to the sub-configuration s among the M sub-configurations, and P is the default number of antenna ports corresponding to the CSI-RS resources.

[0299] For example, the first value may be M P s The sum of P s is the number of antenna ports corresponding to the sub-configuration s in the M sub-configurations. That is, the minimum value of the first value may not be limited.

[0300] For example, Among them, P s is the number of antenna ports corresponding to sub-configuration s among the M sub-configurations.

[0301] For example, the first value may be L P s The sum of P s is the number of antenna ports corresponding to the sub-configuration s in the M sub-configurations. Similarly, the minimum value of the first value may not be limited.

[0302] For example, Among them, P s is the number of antenna ports corresponding to subconfiguration s in the M subconfigurations. L is the total number of subconfigurations configured in the CSI reporting configuration.

[0303] For example, as shown in Figure 2B , resource #1 corresponds to SD pattern #1 and SD pattern #2. SD pattern #1 corresponds to 32 antenna ports, while SD pattern #2 corresponds to 16 antenna ports. Furthermore, under SD pattern #1, subconfigurations #1 through #3 correspond to different PD offsets. P is 32.

[0304] in,

[0305] or,

[0306] or,

[0307] Alternatively, in a fourth manner, when the sub-configuration in the CSI report configuration corresponds to joint adaptation between SD and PD, specifically, corresponds to joint adaptation between the first type of SD (type 1 SD) and PD, the terminal 101 can determine that the number of antenna ports is equal to the product of M and P.

[0308] Exemplarily, at this time, the number of antenna ports = M × P, where P is the default number of antenna ports corresponding to the CSI-RS resource. M is the number of sub-configurations associated with the CSI-RS resource, and the sub-configuration associated with the CSI-RS resource belongs to X sub-configurations.

[0309] In one example, when the CSI report configuration corresponds to joint adaptation between type 1 SD and PD, and the CSI-RS resource corresponds to joint adaptation between type 1 SD and PD, the terminal 101 determines that the number of antenna ports of the M sub-configurations is equal to P. That is, the terminal 101 determines that the number of antenna ports of each sub-configuration in the M sub-configurations is configured as P.

[0310] In one example, when a subconfiguration in a CSI report configuration corresponds to joint adaptation between a first type of SD (type 1 SD) and PD, and a CSI-RS resource corresponds to joint adaptation between a first type of SD and PD, if Ps is less than P, terminal 101 does not expect the CSI-RS resource to be configured with a PD pattern under the first type of SD pattern. For a subconfiguration that is not configured with a PD pattern, the PD offset may be defaulted to 0. Alternatively, under the condition that subconfiguration s and subconfiguration m (s≠m) correspond to the same type 1 SD pattern, terminal 101 does not expect subconfiguration s and subconfiguration m to be configured with different PD offsets.

[0311] Accordingly, terminal 101 determines that the number of antenna ports is equal to the product of M and P.

[0312] For example, as shown in Figure 2D , in the CSI reporting configuration, the subconfiguration corresponds to joint adaptation between type 1 SD and PD, and resource #1 corresponds to joint adaptation between type 1 SD and PD. Subconfigurations #1 through #3 correspond to SD pattern #1, with a corresponding number of antenna ports of 32. Subconfigurations #4 through #6 correspond to SD pattern #1, with a corresponding number of antenna ports of 16. P is 32, and the PD offset corresponding to subconfiguration #4 is 0. Therefore, subconfigurations #5 and #6 are not configured in the CSI reporting configuration because their number of antenna ports is not 32 and their PD offset is not 0.

[0313] Terminal 101 determines that the number of antenna ports corresponding to resource #1 = 3×32 + 1×0 = 96.

[0314] In one example, when the sub-configuration in the CSI report configuration corresponds to joint adaptation between type 1 SD and PD, if Pc is less than P, the terminal 101 does not expect the CSI-RS resource to be configured with multiple PD patterns under the SD pattern corresponding to Pc. c is the number of antenna ports corresponding to pattern c in different SD patterns, and P is the number of default antenna ports corresponding to CSI-RS resources.

[0315] In one example, the terminal 101 does not expect the network device 102 to configure the first type of joint adaptation between the SD and the PD. That is, if joint adaptation occurs, it will only be the second type of joint adaptation between the SD and the PD.

[0316] The fifth method is that when the sub-configuration in the CSI report configuration corresponds to the joint adaptation between SD and PD, specifically, corresponds to the joint adaptation between the second type of SD (type 2 SD) and PD, the terminal 101 can determine that the number of antenna ports is equal to the product of M and P.

[0317] Exemplarily, at this time, the number of antenna ports = M × P, where P is the default number of antenna ports corresponding to the CSI-RS resource. M is the number of sub-configurations associated with the CSI-RS resource, and the sub-configuration associated with the CSI-RS resource belongs to X sub-configurations.

[0318] For example, as shown in Figure 2C, resource #1 corresponds to the same SD pattern, SD pattern #1. Resource #4 corresponds to the same SD pattern, SD pattern #2. Both SD patterns #1 and #2 have the same number of antenna ports: 8. Different subconfigurations correspond to different PD offsets. Therefore, the number of antenna ports corresponding to resource #1 = M × P = 3 × 8 = 24.

[0319] The above description is merely an exemplary description, and all solutions for the terminal 101 to determine the number of antenna ports should fall within the scope of protection of this disclosure.

X and M are positive integers, and M is less than or equal to X. This prevents the number of antenna ports scheduled by the network device from exceeding the terminal's capabilities, thereby improving the availability and reliability of controlling network energy consumption overhead.

[0364] In the above embodiment, the network device can determine the number of antenna ports to avoid the number of scheduled antenna ports exceeding the capability of the terminal, thereby improving the availability and reliability of controlling network energy consumption overhead.

[0365] The above process is further illustrated by the following examples:

[0366] In an embodiment of the present disclosure, taking the NES scenario as an example, of course, the solution of the present disclosure is not limited to the NES scenario. Among them, a CSI report config includes multiple sub-configurations, and the CSI report config corresponds to the joint adaptation of SD and PD, designs corresponding rules, and determines the port counting rules for the corresponding CSI-RS resource.

[0367] Terminal side:

[0368] Under the condition that a CSI report config contains multiple reporting sub-configurations (sub-configuration), and the CSI report config corresponds to the joint adaptation (adaptation) of SD and PD, if a CSI-RS resource is associated with M sub-configs among the X sub-configurations included in the report, the terminal determines the port number corresponding to the CSI-RS resource based on the following rules:

[0369] Solution 1: For the joint adaptation of type 2 SD and PD, the number of ports it occupies is equal to: M×P; Solution 2: For type

[0370] 1 joint adaptation of SD and PD, the number of ports it occupies is as follows: [[ID=1④]]

[0371] Solution 2-1: Or, Or [[ID=②2]]

[0372] Solution 2-2: M×P;

[0373] Among them, the number of antenna ports corresponding to M sub-configurations is equal to P;

[0374] [[ID=2⑨]]If the port number Ps of the SD corresponding to the CSI-RS is less than P, the terminal does not expect the CSI-RS resource to configure multiple PD patterns under the SD;

[0375] If Pc is less than P, the terminal does not expect the CSI-RS resource to configure multiple PD patterns under the SD pattern corresponding to Pc, P c is the number of antenna ports corresponding to pattern c in different SD patterns.

[0376] Solution 2-3: M×P, the terminal does not expect to configure the joint adaptation of type 1 SD and PD;

[0377] Among them, P is the default port number of CSI-RS resource based on nrofports configuration or the maximum number of antenna ports corresponding to CSI-RS resource, P s The number of ports associated with sub-configuration s. The CSI-RS resource is associated with sub-configuration s.

[0378] For X, it is defined as follows:

[0379] For PCSI-RS resource, X = L is the number of configured sub-configs;

[0380] For SP CSI-RS resource, X = L is the number of configured sub-configs, or X = N is the number of activated sub-configs;

[0381] For AP CSI-RS resource, X = N is the number of activated sub-configs;

[0382] Alternatively, X can be defined as follows:

[0383] For PCSI report, X = L is the number of configured sub-configs;

[0384] For SP CSI report, X = L is the number of configured sub-configs, or X = N is the number of activated sub-configs;

[0385] For AP CSI report, X=N is the number of activated sub-configs.

[0386] Network device side:

[0387] A CSI report configuration contains multiple reporting sub-configurations, and the CSI report configuration corresponds to SD and PD joint adaptation. If a CSI-RS resource is associated with M sub-configurations out of X sub-configurations contained in the report, the network device determines the number of ports corresponding to the CSI-RS resource based on the following rules:

[0388] Solution 1: For type 2 SD and PD combined adaptation, the number of ports occupied is equal to: M × P;

[0389] Solution 2: For the joint adaptation of type 1 SD and PD, the number of ports it occupies:

[0390] Solution 2-1: Or, Or

[0391] Solution 2-2: M × P;

[0392] Among them, the number of antenna ports corresponding to the configured M sub-configurations is equal to P;

[0393] If the port number Ps of the SD corresponding to the CSI-RS is less than P, the network device does not configure CSI-RS resources and configures multiple PD patterns under the SD;

[0394] Pc is less than P, the network device configures CSI-RS resources and corresponds to one PD pattern under the SD pattern corresponding to Pc, P c is the number of antenna ports corresponding to pattern c in different SD patterns.

[0395] Solution 2-3: M × P, the network device does not configure the joint adaptation of type 1 SD and PD;

[0396] Among them, P is the number of ports configured by the CSI-RS resource based on nrofports, P s is the number of ports associated with sub-configuration s, and the CSI-RS resource is associated with sub-config s;

[0397] For X, it is defined based on the following method:

[0398] For the P CSI-RS resource, X = L is the number of configured sub-configs;

[0399] For the SP CSI-RS resource, X = L is the number of configured sub-configs, or X = N is the number of activated sub-configs;

[0400] For the AP CSI-RS resource, X = N is the number of activated sub-configs;

[0401] Or, X can also be defined based on the following method <着

[0402] For the P CSI report, X = L is the number of configured sub-configs;

[0403] For SP CSI report, X = L is the number of configured sub-configs, or X = N is the number of activated sub-configs;

[0404] For AP CSI report, X=N is the number of activated sub-configs.

[0405] The following will describe the specific implementation of the present invention from the perspective of the terminal:

[0406] In Example 1, it is assumed that the terminal is a Rel-18 or later terminal and supports the NES feature. To support measurement reporting for multiple SDs and / or multiple power standards, the NES supports sub-CSI reporting for multiple sub-configurations defined for the same CSI report config. Compared to the existing mechanism where one CSI report config corresponds to one CSI, the Rel-18 NES corresponds one CSI report config to multiple sub-configurations, with each sub-configuration corresponding to a sub-CSI report, effectively improving the performance of dynamic CSI measurement reporting.

[0407] The solution of the present invention mainly considers the SD and PD joint adaptation scenario corresponding to the CSI-report, designs corresponding rules, and determines the port counting rules corresponding to the CSI-RS resource.

[0408] Under the condition that L sub-configurations are configured in the CSI-report, among the X sub-configurations, for a specific CSI-RS resource, if the CSI-RS resource is associated with M sub-configurations, and M sub-configurations belong to the X sub-configurations, then the number of antenna ports corresponding to the CSI-RS resource is associated with M. For specific rules, see the following embodiment.

[0409] In one possible implementation, X is associated with a sub-config configured or activated in a CSI-report, and is defined as follows:

[0410] For P CSI-RS resource, X = L is the number of sub-configs configured for CSI-report;

[0411] For SP CSI-RS resource, X = L is the number of configured sub-configs, or X = N is the number of activated sub-configs;

[0412] AP CSI-RS resource, X = N is the number of activated sub-configs;

[0413] In one possible implementation, X is associated with a sub-config configured or activated in a CSI-report, and is defined as follows:

[0414] If the CSI-report is a periodic CSI-report, X = L is the number of sub-configs configured for the CSI-report;

[0415] If the CSI-report is a semi-persistent CSI-report, X=L is the number of sub-configs configured for the CSI-report, or X=N is the number of activated sub-configs;

[0416] For AP CSI report, X = N is the number of activated sub-configs;

[0417] Define P as the default number of antenna ports. Exemplarily, P is based on the nrofPorts configuration corresponding to the CSI-RS resource or is the maximum number of antenna ports corresponding to the CSI-RS resource. Define Ps as the number of antenna ports corresponding to sub-config s, where the CSI-RS resource is associated with sub-config s, and Ps ≤ P.

[0418] Implementation 1: For the combined type 2 SD and PD method, if a CSI-RS resource is associated with M of the X sub-configurations included in the report, the number of ports associated with the resource is equal to: M × P, where P is the default number of antenna ports. For example, as shown in Figure 2C, if the number of antenna ports configured for CSI-RS1 is P = 8, then the number of ports corresponding to the CSI-RS report for CMR#1 is equal to: 8 × 3 = 24.

[0419] Implementation 2: For type 1 SD and PD combined, if a CSI-RS resource is associated with M sub-configurations out of the X sub-configurations included in the report, the number of ports associated with the resource is equal to:

[0420] Implementation 2-1: Among them, P, P sDetermined based on the above definition. For example, as shown in FIG2B , the number of antenna ports corresponding to the CSI-RS report of resource #1 is equal to: 32×3+16×3=144.

[0421] Implementation 2-2: If the number of ports corresponding to the sub-config#s corresponding to the CSI-RS resource is P s If it is not equal to P, the terminal does not expect sub-config s to configure power offset, and / or the terminal does not expect sub-config m to exist (m≠s), and sub-config m and sub-config s correspond to the same type 1SD pattern (eg, the corresponding number of ports P). s ), and corresponding to different power offsets. For example, if a sub-config does not have a corresponding power offset configured, the terminal can interpret it as power offset = 0. Based on the above restrictions, different power offsets corresponding to different PDs can only be associated with a sub-config with a port number of P. In this scenario, the corresponding number of ports is equal to: M × P.

[0422] For example, as shown in FIG2D , if P corresponding to CMR# 1 = 32, then the number of ports corresponding to the CSI-report of resource # 1 is equal to: 32×3=96.

[0423] Implementation 2-3: To avoid computational complexity and reduce terminal processing complexity, the terminal does not allow Type 1 SD and PD joint adaptation. That is, the terminal does not expect to configure Type 1 SD and PD joint adaptation in one CSI-report.

[0424] The embodiment of the present invention mainly designs rules to determine the corresponding port counting rules in the scenario of SD and PD joint adaptation, which is conducive to achieving consistent understanding between network devices and terminals.

[0425] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network device, etc.) in any of the above methods.

[0426] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions.
