[0185] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0186] As shown in FIG. 1A , a communication system 100 includes a terminal 101 and a network device 102 .

[0187] 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.

[0188] 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 .

[0189] In some embodiments, the access network device 102-1 is, for example, a node or device that accesses a terminal to a wireless network.

The CU-DU structure may be used to separate the protocol layers of the access network device, with some functions of the protocol layers being centrally controlled by the CU, and the remaining functions of some or all of the protocol layers being distributed in the DU, which is centrally controlled by the CU, but is not limited thereto.

[0191] 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 element 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).

[0192] 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.

[0193] In some embodiments, the terminal 101 is connected to the core network device 102 - 2 through the access network device 102 - 1 .

[0194] 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.

[0195] 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 .

[0196] The embodiments of the present disclosure may 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), 6th generation mobile communication system (6G), 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.

[0197] An SBFD-aware terminal can perform SBFD operations on semi-static downlink (DL) symbols and semi-static flexible symbols indicated by common TDD configuration signaling, as shown in Figure 1B. On SBFD symbols, the SBFD operations include at least one of the following:

[0198] The terminal performs uplink transmission within the uplink subband (UL subband);

[0199] The terminal performs downlink reception within the DL subband range;

[0200] Figure 1C shows an example of the UL subband, DL subband, and guard band. The guard band provides frequency domain isolation and suppresses self-interference. Given that a terminal only has half-duplex capability, it can only perform one of the SBFD operations in the same time domain unit: uplink transmission or downlink reception.

[0201] As described above, for an SBFD terminal, one possible behavior thereof on an SBFD symbol includes: performing downlink transmission within a frequency domain corresponding to a DL subband.

[0202] To obtain the channel state information (CSI) within the frequency domain corresponding to the DL subband, the terminal can perform corresponding CSI measurements based on the following Channel State Information-Reference Signal (CSI-RS) resource configuration:

[0203] The corresponding CSI-RS resource configuration methods may include one or more of the following:

[0204] Different DL subbands are configured with different CSI-RS resources, where two CSI-RS resources are associated;

[0205] Different DL subbands are configured with the same CSI-RS resource for CSI measurement. The CSI-RS resource can be configured based on different DL subbands and / or Guard bands, and the configured resources can be discontinuous; alternatively, the CSI-RS resource is still configured as a continuous resource based on the active Bandwith Part (active BWP), and the terminal excludes resources other than the DL subband and / or Guard band.

[0206] After performing measurements based on CSI-RS resources, the terminal reports the CSI measurement results. For downlink resources corresponding to SBFD symbols and non-downlink symbols, the corresponding CSI measurement results are different due to the different downlink frequency ranges. Therefore, any of the following CSI reporting configurations can be used:

[0207] Mode 1: Configure different CSI reports based on different symbol types, for example, different CSI reports are configured based on SBFD symbols and non-SBFD symbols.

[0208] Mode 2: Configure the same CSI report based on different symbol types.

[0209] Among them, the above-mentioned method 1 is conducive to the terminal reporting CSI measurement results of different symbol types based on different reporting configurations. However, method 1 increases the configuration overhead of the CSI report configuration (CSI report config).

[0210] Among them, the above-mentioned method 2 can effectively reduce the configuration overhead of the corresponding CSI report config, but it needs to carry CSI measurement results of two symbol types.

[0211] In addition, to reduce network device power overhead, 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 overhead. Taking into account the dynamic adjustment (spatial adaptation, SD) pattern of spatial elements or transmission power, CSI reporting with sub-configuration granularity can be provided. For the same CSI report configuration, it can contain L sub-configurations, each sub-configuration is associated with a specific SD pattern and / or power.

[0212] Taking each sub-config as being associated with an SD pattern as an example, the corresponding CSI report config structure is shown in FIG1D .

[0213] The above method can carry the CSI corresponding to multiple SD patterns / patterns by introducing multiple sub-reports in the CSI report configuration, but does not consider the impact of different symbol types in the SBFD scenario.

[0214] The present disclosure provides the following information transmission method, apparatus, and storage medium. The CSI reporting configuration can be used in SBFD scenarios, so that CSI measurements can be performed and CSI measurement results can be reported based on one or more sub-configurations included in the CSI reporting configuration, thereby reducing the signaling overhead of the CSI reporting configuration and improving the reliability of CSI measurement reporting.

[0215] FIG2 is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to an information transmission method, which includes:

[0216] Step S2101 : The network device 102 sends a CSI report configuration to the terminal 101 .

[0217] In some embodiments, the CSI reporting configuration is used to configure the terminal 101 to perform CSI reporting. In some embodiments, the CSI reporting configuration may include one or more sub-configurations, thereby reducing the signaling overhead of the CSI reporting configuration.

[0218] In one example, the CSI reporting configuration is used to configure the terminal 101 to report CSI measurement results. In the embodiment of the present disclosure, the CSI reporting configuration is used in the SBFD scenario, which can be used to configure the terminal 101 to report CSI measurement results corresponding to different symbol types based on different sub-configurations.

[0219] In some embodiments, terminal 101 receives the CSI reporting configuration.

[0220] Step S2102 : The terminal 101 determines that the CSI reporting configuration is for the SBFD scenario.

[0221] In some embodiments, the terminal 101 may determine that the CSI reporting configuration is for the SBFD scenario in at least one of the following ways, but not limited to:

[0222] In method 1, based on the explicit signaling sent by the network device 102 , it is determined that the CSI report configuration is for the SBFD scenario.

[0223] In one example, the display signaling may be the first signaling, and the first signaling may include but is not limited to Radio Resource Control (RRC) signaling; Downlink Control Information (DCI); Medium Access Control Element (MAC CE), etc. The present disclosure does not limit the first signaling.

[0224] In one example, the display signaling may include CSI report configuration.

[0225] In one example, display signaling may be determined based on a CSI reporting configuration.

[0226] Exemplarily, the terminal 101 determines that a first information element (IE) is added to the first signaling, where the first IE may be used to indicate that the CSI report configuration is for an SBFD scenario. For example, when the first IE indicates SBFD, the terminal 101 may determine that the CSI report configuration is for an SBFD scenario.

[0227] Exemplarily, when a first IE is added to the first signaling and the first IE indicates non-SBFD, the terminal 101 may determine that the CSI report configuration is used for other scenarios, such as a Network Energy Saving (NES) scenario.

[0228] Exemplarily, when the first IE is added or included in the first signaling, the terminal 101 may directly determine that the CSI report configuration is for an SBFD scenario.

[0229] Exemplarily, when the first IE is not added or included in the first signaling, the terminal 101 may determine that the CSI report configuration is used for other scenarios, such as the NES scenario.

[0230] In one example, display signaling may be determined based on the CSI sub-configuration.

[0231] Exemplarily, if the first signaling includes a second configuration, the terminal 101 may determine that the CSI report configuration is used for the SBFD scenario, wherein the second configuration is a configuration of the SBFD symbol type associated with each of the sub-configurations.

[0232] For example, the first signaling includes a second configuration, and the second configuration indicates that the symbol type associated with subconfiguration #1 is SBFD, the symbol type associated with subconfiguration #2 is non-SBFD, ..., then the terminal 101 can determine that the CSI report configuration is used for the SBFD scenario.

[0233] It should be noted that if network device 102 performs both uplink transmission and downlink reception on a symbol, the symbol type of the symbol is SBFD, i.e., the symbol is an SBFD symbol, such as slots #n+1, #n+2, and #n+3 in FIG1B . If network device 102 performs only uplink transmission or downlink reception on a symbol, the symbol type of the symbol is non-SBFD, i.e., the symbol is a non-SBFD symbol, such as slots #n and #n+4 in FIG1B .

[0234] Exemplarily, if the first signaling does not include the second configuration, the terminal 101 may determine that the CSI report configuration is used for other scenarios, such as the NES scenario.

[0235] In some embodiments, the CSI-RS resources corresponding to the SBFD symbols and the non-SBFD symbols may be the same.

[0236] In one example, based on the aforementioned optional configuration of CSI-RS resources, if the CSI-RS resources corresponding to the same CSI-RS identifier can be configured on either SBFD symbols or non-SBFD symbols, then the terminal 101 can accordingly perform CSI measurements within one or more downlink subbands (DL subbands) of SBFD symbols, or within the uplink and downlink bandwidth (DL BWP) of non-SBFD symbols, based on the CSI-RS resources corresponding to the same CSI-RS identifier.

[0237] Exemplarily, the non-continuous frequency domain range on the SBFD symbol is based on a CSI-RS resource. For example, in the scenario where CSI-RS resource #1 is configured, the network device 102 can also configure CSI-RS resource #1 in the non-SBFD symbol, and the terminal 101 excludes frequency domain resources outside the DL subband range on the SBFD symbol.

[0238] In some embodiments, the CSI-RS resources corresponding to the SBFD symbols and the non-SBFD symbols may be different.

[0239] Based on the aforementioned optional configuration of CSI-RS resources, if the CSI-RS resources corresponding to the same CSI-RS identifier can only be configured on SBFD symbols or non-SBFD symbols, then the terminal 101 can only perform CSI measurement on one symbol type based on the CSI-RS resources corresponding to the same CSI-RS identifier.

[0240] Exemplarily, the non-continuous frequency domain range on the SBFD symbol is based on a CSI-RS resource. For example, in the scenario where CSI-RS resource #1 is configured, the CSI-RS resource #1 is non-continuous in the frequency domain range. The network device 102 may also configure CSI-RS resource #2 in the non-SBFD symbol, and the CSI-RS resource #2 is non-continuous in the frequency domain range.

[0241] It should be noted that, in the embodiments of the present disclosure, it can be applied in scenarios where the CSI-RS resources corresponding to SBFD symbols and non-SBFD symbols are the same, or it can be applied in different scenarios, and the present disclosure does not impose any restrictions on this.

[0242] The above description is merely an exemplary description, and all solutions in which the terminal 101 determines the CSI report configuration for the SBFD scenario based on the first signaling sent by the network device 102 should fall within the protection scope of the present disclosure.

[0243] Mode 2: Based on a predefined rule, determine that the CSI report configuration is used for the SBFD scenario.

[0244] In an example, if the CSI report identifier belongs to a first identifier set, the terminal 101 may determine that the CSI report configuration is for the SBFD scenario. The first identifier set is a set of CSI report identifiers that can be used in the SBFD scenario.

[0245] Exemplarily, the first identifier set can be determined based on a predefined rule or a predefined method. For example, the protocol stipulates that the first identifier set is {0, 1}. If the CSI report identifier corresponding to the CSI report configuration is 0 or 1, the terminal 101 can determine that the CSI report configuration is used for the SBFD scenario.

[0246] Exemplarily, the first identifier set can be indicated by the network device 102 through signaling. For example, the network device 102 sends a fourth signaling to the terminal 101, and the fourth signaling configures the first identifier set as {1, 2}. If the CSI report identifier corresponding to the CSI report configuration is 1 or 2, the terminal 101 can determine that the CSI report configuration is used for the SBFD scenario.

[0247] Exemplarily, the first identifier set may be determined based on a predefined rule and an indication by the network device 102. For example, the protocol stipulates that the first identifier set is {0, 1}, and the first identifier set indicated by the network device 102 is {1}. If the CSI reporting identifier corresponding to the CSI reporting configuration is 1, the terminal 101 may determine that the CSI reporting configuration is used for the SBFD scenario.

[0248] Exemplarily, if the CSI report identifier does not belong to the first identifier set, the terminal 101 may determine that the CSI report configuration is used for other scenarios, such as the NES scenario.

[0249] In an example, if each sub-configuration does not include the NES parameter, the terminal 101 may determine that the CSI reporting configuration is used for the SBFD scenario.

[0250] For example, the NES parameters may include but are not limited to at least one of the following:

[0251] Spatial Adaptation (SD) pattern related parameters;

[0252] Power Adaptation (PD) mode related parameters;

[0253] Cell list.

[0254] In an example, if at least one sub-configuration includes an NES parameter, the terminal 101 may determine that the CSI reporting configuration is used for other scenarios, such as the NES scenario.

[0255] In one example, if the sub-configuration includes a cell list, and there are identical cells between the first cell list and the second cell list, the terminal 101 can determine that the CSI report configuration is used for the SBFD scenario, wherein the first cell list is a cell list included in the first sub-configuration, and the second cell list is a cell list included in the second sub-configuration.

[0256] It can be understood that in the NES scenario, the cell lists corresponding to different sub-configurations are only completely the same or completely different. In the embodiment of the present disclosure, if the sub-configuration is introduced in the SBFD scenario and the cell list included in the sub-configuration contains the same cells, the terminal 101 can determine that the current scenario is an SBFD scenario.

[0257] Exemplarily, if a sub-configuration includes a cell list, and the cell lists included in different sub-configurations are completely the same or completely different, the terminal 101 may determine that the CSI reporting configuration is for other scenarios, such as an NES scenario.

[0258] For example, the sub-configuration includes a cell list, and the cell lists included in any two sub-configurations do not contain the same cell. The terminal 101 may determine that the CSI reporting configuration is for other scenarios, such as the NES scenario.

[0259] For another example, the sub-configuration includes a cell list, and the cell lists included in any two sub-configurations are the same. The terminal 101 may determine that the CSI reporting configuration is used for other scenarios, such as the NES scenario.

[0260] In an example, if the first resource satisfies the first condition, the terminal 101 may determine that the CSI report configuration is for the SBFD scenario, where the first resource may include but is not limited to at least one of the following:

[0261] CSI-RS resources associated with the CSI report configuration;

[0262] The resources corresponding to the CSI report.

[0263] Exemplarily, if the CSI-RS resources associated with the CSI report configuration are configured based on SBFD symbols and / or non-SBFD symbols, the terminal 101 may determine that the CSI report configuration is used for the SBFD scenario; otherwise, the terminal 101 may determine that the CSI report configuration is used for other scenarios.

[0264] Exemplarily, if the corresponding CSI report is reported based on SBFD symbols and / or non-SBFD symbols, the terminal 101 may determine that the CSI report configuration is for the SBFD scenario; otherwise, the terminal 101 may determine that the CSI report configuration is for other scenarios.

[0265] Exemplarily, if the corresponding CSI report is reported based on the frequency domain range corresponding to the downlink BWP and / or downlink subband, the terminal 101 can determine that the CSI report configuration is used for the SBFD scenario; otherwise, the terminal 101 can determine that the CSI report configuration is used for other scenarios.

[0266] The above description is merely an exemplary description, and any solution in which the terminal 101 determines, based on predefined rules, that the CSI report configuration is used for the SBFD scenario should fall within the scope of protection of the present disclosure.

[0267] In some embodiments, the terminal 101 may determine, based on a predefined rule and the first signaling sent by the network device 102 , that the CSI report configuration is for the SBFD scenario.

[0268] For example, when the CSI report identifier belongs to the first identifier set, the first signaling includes the first IE, and the first IE indicates SBFD, the terminal 101 determines that the CSI report configuration is used for the SBFD scenario.

[0269] For another example, each sub-configuration does not include the NES parameter, and the first signaling includes the first IE, and the terminal 101 determines that the CSI report configuration is used for the SBFD scenario.

[0270] For another example, if the sub-configuration includes a cell list, and the first cell list and the second cell list contain the same cells, the first signaling includes the second configuration, and the terminal 101 determines that the CSI report configuration is for the SBFD scenario.

[0271] The above description is merely exemplary, and any solution in which the terminal 101 determines that the CSI report configuration is used for the SBFD scenario based on predefined rules and the signaling sent by the network device 102 should fall within the scope of protection of the present disclosure.

[0272] Step S2103: Terminal 101 determines the symbol type associated with each sub-configuration.

[0273] In some embodiments, the terminal 101 may determine that the CSI reporting configuration is for the SBFD scenario in at least one of the following ways, but not limited to:

[0274] Mode 1: Determine the symbol type associated with each sub-configuration based on the display signaling sent by the network device 102.

[0275] In an example, the terminal 101 receives second signaling sent by the network device 102, where the second signaling is used to indicate a symbol type associated with each of the sub-configurations.

[0276] For example, the second signaling may indicate that the symbol type associated with subconfiguration #1 is SBFD, the symbol type associated with subconfiguration #2 is non-SBFD, .... Terminal 101 may determine, based on the second signaling, that the symbol type associated with subconfiguration #1 is SBFD, the symbol type associated with subconfiguration #2 is non-SBFD, ....

[0277] Illustratively, the second signaling and the first signaling may be signalings of the same or different types, which is not limited in the present disclosure.

[0278] Mode 2: Determine the symbol type associated with each sub-configuration based on a predefined rule.

[0279] In one example, the correspondence between the CSI sub-report identifier and the symbol type may be agreed upon by a protocol, and the terminal 101 determines the symbol type associated with each sub-configuration according to the CSI sub-report identifier included in each sub-configuration.

[0280] For example, the protocol stipulates that the symbol type corresponding to CSI sub-report identifiers 1, 2, and 5 is SBFD, and the symbol type corresponding to CSI sub-report identifiers 3 and 4 is non-SBFD. Terminal 101 can determine that the symbol type associated with sub-configuration #1, sub-configuration #2, and sub-configuration #5 is SBFD, and the symbol type associated with sub-configuration #3 and sub-configuration #4 is non-SBFD.

[0281] In one example, the relationship between the sub-configuration identifier associated with an SBFD symbol and the sub-configuration identifier associated with a non-SBFD symbol may be stipulated by a protocol. For example, the sub-configuration identifier associated with an SBFD symbol is smaller than the sub-configuration identifier associated with a non-SBFD symbol. Alternatively, the sub-configuration identifier associated with an SBFD symbol is larger than the sub-configuration identifier associated with a non-SBFD symbol.

[0282] Exemplarily, if the sub-configuration identifier associated with the SBFD symbol is smaller than the sub-configuration identifier associated with the non-SBFD symbol, when the first sub-configuration identifier is smaller than the second sub-configuration identifier, the terminal 101 can determine that the symbol type associated with the first sub-configuration is SBFD, and the symbol type associated with the second sub-configuration is non-SBFD.

[0283] Exemplarily, if the sub-configuration identifier associated with the SBFD symbol is greater than the sub-configuration identifier associated with the non-SBFD symbol, when the first sub-configuration identifier is greater than the second sub-configuration identifier, the terminal 101 can determine that the symbol type associated with the first sub-configuration is SBFD, and the symbol type associated with the second sub-configuration is non-SBFD.

[0284] The above description is merely an exemplary description, and the present disclosure does not limit the scheme in which the terminal 101 determines the symbol type associated with each sub-configuration.

[0285] In step S2104, the terminal 101 determines the CSI-RS resources associated with each of the sub-configurations.

[0286] In some embodiments, the CSI-RS resource lists associated with different sub-configurations may be different.

[0287] Accordingly, the terminal 101 may determine the CSI-RS resource associated with each sub-configuration in at least one of the following ways, but not limited to:

[0288] Mode 1: Based on explicit signaling sent by the network device 103, the CSI-RS resource associated with each sub-configuration is determined.

[0289] In one example, the network device 103 sends a third signaling to the terminal 101. The third signaling may be used to indicate at least one of the following:

[0290] A list of CSI-RS resources associated with each sub-configuration;

[0291] Each of the subconfigurations is associated with a symbol type.

[0292] The terminal 101 determines the CSI-RS resources associated with each of the sub-configurations based on the third signaling.

[0293] Exemplarily, the third signaling is used to indicate a CSI-RS resource list associated with each sub-configuration, and the terminal 101 can determine the CSI-RS resource associated with each sub-configuration based on the third signaling. The CSI-RS resource is from the CSI-RS resource list associated with the sub-configuration.

[0294] Exemplarily, the third signaling is used to indicate the symbol type associated with each of the sub-configurations, and the terminal 101 determines the CSI-RS resource associated with each of the sub-configurations based on the symbol type associated with the sub-configuration.

[0295] For example, the symbol type associated with the first sub-configuration is SBFD, and the terminal 101 may determine that the CSI-RS resources associated with the first sub-configuration include one or more CSI-RS resources configured on SBFD symbols.

[0296] For another example, the symbol type associated with the first sub-configuration is non-SBFD, and the terminal 101 may determine that the CSI-RS resources associated with the first sub-configuration include one or more CSI-RS resources configured on non-SBFD symbols.

[0297] Mode 2: Determine the CSI-RS resource associated with each sub-configuration based on a predefined method.

[0298] Exemplarily, the symbol type associated with the first sub-configuration is SBFD, and the terminal 101 may determine that the CSI-RS resources associated with the first sub-configuration include one or more CSI-RS resources configured on SBFD symbols.

[0299] Exemplarily, the symbol type associated with the first sub-configuration is non-SBFD, and the terminal 101 may determine that the CSI-RS resources associated with the first sub-configuration include one or more CSI-RS resources configured on non-SBFD symbols.

[0300] It should be noted that, for the above-mentioned methods 1 and 2 for determining the CSI-RS resources associated with each sub-configuration, the corresponding configuration parameters can be configured based on the sub-configuration, for example, different sub-configurations correspond to different CSI-RS resource lists, or the configuration parameters can be configured based on the CSI report configuration, for example, different sub-configurations correspond to the same CSI-RS resource lists. This disclosure is not limited to this.

[0301] In some embodiments, the CSI-RS resources corresponding to the SBFD symbols and the non-SBFD symbols are the same, and the CSI-RS resource lists associated with different sub-configurations are also the same.

[0302] For the terminal 101, it can first determine a first resource set, which is a set of CSI-RS resources associated with the CSI reporting configuration. Further, it can be determined that the CSI-RS resources associated with each sub-configuration belong to the first resource set.

[0303] In an example, the first resource set is assumed to include n CSI-RS resources, and the CSI-RS resources associated with each sub-configuration may be part or all of the n CSI-RS resources.

[0304] For example, the set of CSI-RS resources associated with each sub-configuration is the same as the first resource set.

[0305] For another example, the set of CSI-RS resources associated with each sub-configuration is a subset of the first resource set.

[0306] In step S2105 , the terminal 101 performs CSI measurement in the SBFD scenario and sends the CSI measurement result to the network device 102 .

[0307] In some embodiments, in an SBFD scenario, the terminal 101 measures the CSI-RS based on the symbol type and the associated CSI-RS resource associated with each sub-configuration, obtains a CSI measurement result, and then sends the CSI measurement result to the network device 102.

[0308] In some embodiments, in an SBFD scenario, if the symbol type associated with the first sub-configuration is SBFD, the terminal 101 can measure the CSI-RS associated with the first sub-configuration on the SBFD symbol to obtain a CSI measurement result. Furthermore, the CSI measurement result can be sent to the network device 102 based on the first sub-configuration. At this time, the CSI measurement result includes the CSI measurement result corresponding to the SBFD symbol.

[0309] In some embodiments, in an SBFD scenario, if the symbol type associated with the first sub-configuration is non-SBFD, the terminal 101 can measure the CSI-RS associated with the first sub-configuration on the non-SBFD symbol to obtain a CSI measurement result. Furthermore, the CSI measurement result can be sent to the network device 102 based on the first sub-configuration. At this time, the CSI measurement result includes the CSI measurement result corresponding to the SBFD symbol.

[0310] In some embodiments, the network device 102 receives the CSI measurement results sent by the terminal 101, which may include CSI measurement results corresponding to different symbol types.

[0311] In an example, the symbol type associated with the first sub-configuration is SBFD, and the network device 102 receives the CSI measurement result sent by the terminal based on the first sub-configuration, where the CSI measurement result includes the CSI measurement result corresponding to the SBFD symbol.

[0312] In one example, the symbol type associated with the first sub-configuration is non-SBFD, and the network device 102 receives the CSI measurement result sent by the terminal based on the first sub-configuration, and the CSI measurement result includes the CSI measurement result corresponding to the non-SBFD symbol.

[0313] In some embodiments, considering that the symbol types corresponding to the CSI measurement results reported by the terminal 101 are different based on different symbol types, the network device 102 may configure the report quantity based on different sub-configurations.

[0314] Exemplarily, the reported quantity may include but is not limited to at least one of the following: Channel Quality Indicator (CQI); precoding matrix indicator (PMI); reference signal receiving power (RSRP); reference signal receiving quality (RSRQ).

[0315] For example, the reporting quantity corresponding to the first sub-configuration may include CQI and RSRP, and the reporting quantity corresponding to the second sub-configuration may include PMI, RSRP and RSRQ...

[0316] In some embodiments, considering that the downlink frequency domain ranges corresponding to SBFD symbols and non-SBFD symbols are different, the report frequency domain configuration (reportFreqConfiguration) can be configured based on the sub-configuration. For example, when the symbol type associated with the first sub-configuration is SBFD, the corresponding reportFreqConfiguration can be configured as subband, and when the symbol type associated with the second sub-configuration is non-SBFD, the corresponding reportFreqConfiguration can be configured as wideband.

[0325] In some embodiments, step S2104 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if the CSI-RS resources associated with each sub-configuration are determined by another device or the terminal 101 has already determined the CSI-RS resources associated with each sub-configuration, step S2104 may not be performed.

[0326] In some embodiments, step S2105 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, step S2105 may not be performed when the system is in another scenario, such as an NES scenario, or when the network device 102 obtains CSI measurement results from another execution entity.

[0327] In some embodiments, steps S2101 to S2105 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0359] Step S3202: Acquire CSI measurement results.

[0360] In some embodiments, the CSI measurement result is obtained by the terminal 101 performing CSI measurement in an SBFD scenario.

[0361] In an example, the symbol type associated with the first sub-configuration is SBFD, and the network device 102 receives the CSI measurement result sent by the terminal based on the first sub-configuration, where the CSI measurement result includes the CSI measurement result corresponding to the SBFD symbol.

This improves the reliability of CSI measurement reporting.

[0371] The above content is further illustrated below with examples.

[0372] In the disclosed embodiment, in an SBFD scenario, different sub-reports within the same CSI report configuration carry CSI measurement results of different symbol types, which helps reduce the signaling overhead of the CSI report configuration while improving CSI measurement reporting performance.

[0427] Method 2-1: The network device sends configuration signaling and indicates that the CSI report is configured as an SBFD specific CSI report based on the following method:

[0428] The method is similar to method 1-1 and will not be repeated here;

[0429] In method 2-2, the network device sends configuration signaling. The CSI report configuration includes one or more sub-configurations and indicates the symbol type corresponding to the sub-configuration based on the following method:

[0430] The method is similar to method 1-2 and will not be repeated here.

[0431] In method 2-3, the network device sends configuration signaling. The CSI report configuration includes one or more sub-configurations and configures the CSI-RS resource associated with the sub-configurations based on the following method:

[0432] The CSI-RS resource associated with the sub-configuration is the same as the CSI-RS resource associated with the CSI configuration;

[0433] The CSI-RS resource associated with different sub-configurations is the same.

[0434] The implementation is as follows:

[0435] Assuming the terminal is a Release 18 or later terminal and supports the SBFD feature, the terminal performs corresponding SBFD operations based on SBFD symbols. The SBFD symbols are symbols that configure DL subbands, and / or UL subbands, and / or Guard bands on DL and / or flexible symbols, as shown in Figure 1B.

[0436] Assuming a network device, such as a base station, is Release 18 or later and supports the SBFD feature, the base station performs SBFD operations based on SBFD symbols. The SBFD symbols are symbols that configure DL subbands, UL subbands, and / or Guard bands on DL and / or flexible symbols, as shown in Figure 1B.

[0437] In some embodiments, the corresponding concepts involved in the solutions of the present invention are described as follows:

[0438] SBFD symbols: The base station can perform downlink transmission within the DL subband range on the SBFD symbols configured in the UL subband. Correspondingly, the terminal can perform uplink transmission within the UL subband on the SBFD symbols configured in the UL subband. From another perspective, the downlink resources that can be transmitted by the CSI-RS resource are no longer the DL BWP in which it is located, but the frequency domain range corresponding to the DL subband. The frequency domain resources corresponding to the CSI-RS resource can be continuous or discontinuous.

[0439] Non-SBFD symbols: On non-SBFD symbols corresponding only to the DL BWP transmission range, the downlink resource that can be transmitted by the CSI-RS resource is the DL BWP in which it is located, and the frequency domain resources corresponding to the CSI-RS resource are continuous;

[0440] CSI configuration in SBFD scenarios: As mentioned above, the transmittable downlink resources corresponding to SBFD symbols and non-SBFD symbols are different, which may lead to different CSI measurement results. The CSI configuration in SBFD scenarios in the solution of the present invention refers to the corresponding CSI-RS resource configuration based on the above-mentioned differences in different symbol types. At the same time, the terminal performs CSI-RS measurement and reporting under different symbol types based on the CSI-RS resource configuration;

[0441] The CSI-RS resource corresponding to the SBFD symbol and the non-SBFD symbol is the same: based on the optional configuration method of the CSI-RS resource, if the CSI-RS resource corresponding to the same identifier can be configured on both the SBFD symbol and the non-SBFD symbol; correspondingly, the terminal can perform CSI measurements within one or more DL subband ranges of the SBFD symbol, or perform CSI measurements within the DL BWP range on the non-SBFD symbol based on the CSI-RS resource corresponding to the same identifier. For example, in a scenario where the non-continuous frequency domain range on the SBFD symbol is based on one CSI-RS resource, such as CSI-RS resource#1 configuration, the base station can also configure CSI-RS resource#1 on the non-SBFD symbol, and the terminal excludes frequency domain resources outside the DL subband range on the SBFD symbol;

[0442] The CSI-RS resources corresponding to SBFD symbols and non-SBFD symbols are different: Based on the optional configuration method of CSI-RS resource, if the CSI-RS resource corresponding to the same identifier can only be configured on SBFD symbols or non-SBFD symbols; or, based on the CSI-RS resource corresponding to the same identifier, the terminal can only perform CSI measurement of one symbol type. For example, in the scenario where the non-continuous frequency domain range on the SBFD symbol is based on a CSI-RS resource, for example, CSI-RS resource#1 is configured, the CSI-RS resource#1 is non-continuous in the frequency domain range, and the base station can also configure CSI-RS resource#2 in the non-SBFD symbol, and the CSI-RS resource#2 is non-continuous in the frequency domain range;

[0443] It is worth noting that the solution of the present invention can be applied to scenarios where the CSI-RS resources corresponding to SBFD symbols and non-SBFD symbols are the same, and can also be applied to scenarios where the CSI-RS resources corresponding to SBFD symbols and non-SBFD symbols are different, and the present invention does not limit this.

[0444] In one implementation scenario, the CSI configuration corresponding to the solution of the present invention may be a CSI report config, and correspondingly, the sub-(CSI) configuration corresponding to the solution of the present invention may be a sub-CSI report config, which is not limited by the present invention.

[0445] The solution of the present invention primarily considers scenarios where the same CSI report is configured based on both SBFD and non-SBFD symbol types. By introducing a sub-CSI report configuration corresponding to different symbol types into the CSI report, the terminal can simultaneously report CSI measurement results for different symbol types using the same CSI report resource. This helps reduce CSI configuration overhead while improving the number of CSI measurement reporting types.

[0446] From the perspective of the terminal, the specific process involved in the solution of the present invention includes:

[0447] In step 1, the terminal receives the CSI report configuration and determines, based on embodiment 1-1 or embodiment 2-1, that the CSI report configuration is a CSI report configuration applied in an SBFD scenario.

[0448] In step 2, the terminal receives at least one sub-configuration included in the CSI report, and determines the SBFD symbol type corresponding to the sub-configuration based on embodiment 1-2 or embodiment 2-2.

[0449] In step 3, the terminal receives at least one sub-configuration included in the CSI report, and determines a CSI-RS resource associated with the sub-configuration based on Embodiment 1-3 or Embodiment 2-3.

[0450] Furthermore, the terminal performs corresponding CSI measurement reporting based on the CSI report configuration.

[0451] Correspondingly, from the perspective of the base station, the specific process involved in the solution of the present invention includes:

[0452] Step 1: The base station configures the CSI report configuration applied in the SBFD scenario based on Example 1-1 or Example 2-1, and sends the corresponding CSI configuration.

[0453] In step 2, the base station configures CSI report sub-configurations applied to different symbol types based on embodiment 1-2 or embodiment 2-2, and sends the corresponding sub-configurations.

[0454] Step 3: The base station configures CSI-RS resources associated with the CSI report sub-configuration based on embodiment 1-2 or embodiment 2-2, and sends the corresponding CSI sub-configuration.

[0455] The base station receives corresponding CSI measurement results in corresponding time-frequency domain resources based on the CSI report configuration.

[0456] In Example 1, this embodiment of the present invention primarily considers scenarios where there are no restrictions on CSI-RSs corresponding to SBFD symbols and non-SBFD symbol types. That is, one or more CSI-RSs exist within a CSI configuration, and the CSI-RSs are applied to only one symbol type. In contrast, if the first and second sub-configurations corresponding to the CSI configuration have different associated SBFD symbol types, the CSI-RS lists associated with the first and second sub-configurations are not identical.

[0457] In view of the above scenario, the present invention describes the specific implementation of the present invention from the perspective of the terminal side:

[0458] In Example 1-1, the terminal receives a corresponding CSI reporting configuration and, based on a display signaling indication, determines that the CSI configuration is a CSI configuration for use in an SBFD scenario. Possible implementations include:

[0459] In embodiment 1, the display signaling is determined based on the CSI configuration. For example, if an IE is added to the CSI report, for example, an applied scenario IE, and if the IE indicates SBFD, the terminal determines that the CSI configuration is a CSI configuration applied in the SBFD scenario. If the IE indicates 'not SBFD' or the corresponding IE does not exist, the terminal determines that the CSI configuration is not a CSI configuration applied in the SBFD scenario.

[0460] In embodiment 2, the display signaling is determined based on the sub-configuration. For example, if the sub-configuration includes a configuration of an associated SBFD symbol type, for example, the associated symbol (associated symbol type) = SBFD or = non-SBFD, the terminal determines that the CSI configuration associated with the sub-configuration is a CSI report configuration applied in the SBFD scenario. If the display signaling is not configured, the terminal determines that the CSI configuration associated with the CSI sub-configuration is not a CSI configuration applied in the SBFD scenario.

[0461] The terminal receives the corresponding CSI configuration and determines, based on pre-definition, that the CSI configuration is a CSI configuration applied in the SBFD scenario. Possible implementations include:

[0462] In implementation mode 3, a first set to which a report identifier corresponding to a CSI report configuration in an SBFD scenario belongs is determined by a predefined rule. The first set may be determined based on a signaling indication or a predefined method. For example, if the first set is {0, 1} and the corresponding report id = 0, the terminal determines that the CSI configuration is a CSI configuration applied in an SBFD scenario.

[0463] In implementation mode 4, the terminal determines the type of CSI configuration based on the sub-configuration under the CSI report. Exemplarily, under the condition that the corresponding CSI report contains one or more sub-configurations, for example, two CSI sub-configurations, if any of the sub-configurations does not include NES-related parameters, e.g., SD pattern-related parameters (e.g., portSubsetIndicator-r18), PD pattern-related parameters (e.g., powerOffset-r18), cell lists (e.g., nzp-CSI-RS-ResourceList-r18), or the CSI report sub-configuration includes a cell list, and the cell lists included in different CSI report sub-configurations include the same cell, then the terminal determines that the CSI configuration does not apply to the NES scenario. Correspondingly, the terminal determines that the CSI configuration is a CSI configuration applied in the SBFD scenario.

[0464] In implementation mode 5, the terminal determines the application scenario of the CSI configuration based on the CSI resource configured under the CSI report or the time-frequency domain resource corresponding to the CSI report. For example, when one or more of the following conditions are met,

[0465] One or more CSI resources are configured based on SBFD / non-SBFD symbols.

[0466] The corresponding CSI report is based on SBFD / non-SBFD symbols.

[0467] The corresponding CSI report is reported based on the frequency domain range corresponding to DL BWP / DL subband;

[0468] In Embodiment 1-2, the terminal receives a corresponding CSI configuration, where the CSI configuration signaling includes a CSI subconfiguration, and determines, based on the method of this embodiment, a symbol type corresponding to the subconfiguration. It is noteworthy that, if the symbol type associated with the CSI subconfiguration is an SBFD symbol, the terminal performs corresponding CSI measurement on the SBFD symbol based on the subconfiguration, and reports the CSI result corresponding to the SBFD symbol based on the subconfiguration. Correspondingly, if the symbol type associated with the CSI subconfiguration is a non-SBFD symbol, the terminal performs corresponding CSI measurement on the non-SBFD symbol based on the subconfiguration, and reports the CSI result corresponding to the non-SBFD symbol based on the subconfiguration.

[0469] Possible implementations include:

[0470] In implementation mode 1, the terminal determines the symbol type corresponding to the sub-configuration based on display signaling. The display signaling is determined based on the sub-configuration, exemplarily:

[0471] Exemplarily, under the condition that the first sub-configuration indicates that the associated symbol type is SBFD, eg, symbol type = SBFD, the terminal determines that the sub-configuration is associated with the SBFD symbol;

[0472] Exemplarily, under the condition that the first sub-configuration indicates that the associated symbol type is non-SBFD, e.g., symbol type = non-SBFD, the terminal determines that the sub-configuration is associated with the non-SBFD symbol;

[0473] In implementation mode 2, the terminal determines the symbol type corresponding to the sub-configuration based on a predefined method. The display signaling is determined based on the sub-configuration, exemplarily:

[0474] For example, the correspondence between the size of the sub report id and different symbol types is predefined.

[0475] Exemplarily, under the condition that the sub report id associated with SBFD is less than the sub report id of non-SBFD, if the sub configuration id of the first sub configuration is less than the sub configuration id of the second sub configuration, the terminal determines that the symbol type associated with the first sub configuration is SBFD and the symbol type associated with the second sub configuration is non-SBFD;

[0476] Exemplarily, under the condition that the sub report id associated with SBFD is greater than the sub report id of non-SBFD, if the sub configuration id of the first sub configuration is greater than the sub configuration id of the second sub configuration, the terminal determines that the symbol type associated with the first sub configuration is non-SBFD and the symbol type associated with the second sub configuration is SBFD;

[0477] In embodiments 1-3, the terminal receives the corresponding CSI configuration, the CSI configuration signaling includes a CSI sub-configuration, and based on the method of this embodiment, determines the CSI-RS resource associated with the sub-configuration. It is worth noting that in the corresponding scenario of this embodiment, the CSI-RS resource lists associated with different sub-configurations are not exactly the same.

[0478] Possible implementations include:

[0479] In implementation mode 1, the terminal determines the CSI-RS resource associated with the sub-configuration based on display signaling. The display signaling is determined based on the sub-configuration, exemplarily:

[0480] The terminal determines the associated CSI-RS based on the associated CSI-RS list configured in the CSI sub-configuration;

[0481] In implementation mode 2, the terminal determines the CSI-RS resource associated with the sub-configuration based on display signaling. The display signaling is determined based on the CSI configuration, exemplarily:

[0482] When the CSI-RS resource associated with the CSI configuration is configured based on SBFD and non-SBFD respectively, for example, based on different CSI-RS resource set configurations, or based on the same CSI-RS resource set but based on different resource ids or list index configurations, the terminal determines the associated CSI-RS resource based on the SBFD symbol type associated with the sub-configuration.

[0483] In implementation mode 3, the terminal determines the CSI-RS resource associated with the sub-configuration based on predefined conditions.

[0484] If the first sub-configuration is associated with the SBFD symbol, the terminal determines that the first sub-configuration is associated with all CSI-RS resources configured on the SBFD symbol, where the CSI-RS resources are based on the CSI report configuration;

[0485] If the first subconfiguration is associated with a non-SBFD symbol, the terminal determines that the first subconfiguration is associated with all CSI-RS resources configured on the non-SBFD symbol, where the CSI-RS resources are based on the CSI report configuration;

[0486] Based on any of the above embodiments, the corresponding configuration parameters can be configured based on the sub-configuration, and different sub-configurations correspond to different configuration parameters. They can also be configured based on the CSI configuration, and different sub-configurations correspond to the same configuration parameters. The present invention does not limit this.

[0487] Exemplarily, considering that the base station may have different reporting types based on different SBFD symbol types, the corresponding report quantity may be configured based on different sub-configurations.

[0488] Exemplarily, considering that the DL frequency domain ranges corresponding to the SBFD symbol type and the non-SBFD symbol type are different, the corresponding report frequency domain configuration (reportFreqConfiguration) can be configured based on the sub-report configuration (sub-report config). Exemplarily, if the first sub-configuration is associated with the SBFD symbol type, the corresponding reportFreqConfiguration can be configured as subband; exemplarily, if the second sub-configuration is associated with the non-SBFD symbol type, the corresponding reportFreqConfiguration can be configured as wideband.

[0489] In Example 2, this embodiment of the present invention primarily considers scenarios where the CSI-RS corresponding to SBFD symbols and non-SBFD symbol types is the same CSI-RS. That is, one or more CSI-RSs exist within a CSI configuration, and the CSI-RS is only applied to scenarios with two symbol types. In contrast, if the corresponding first and second sub-configurations within a CSI configuration have different associated SBFD symbol types, the CSI-RS lists associated with the first and second sub-configurations are the same.

[0490] In view of the above scenario, the present invention describes the specific implementation of the present invention from the perspective of the terminal side:

[0491] In Example 2-1, the terminal receives the corresponding CSI configuration and determines, based on a predefined or displayed signaling indication, that the CSI configuration is a CSI configuration applied in an SBFD scenario. The specific implementation method is the same as that of Example 1-1 and will not be repeated here.

[0492] In Example 2-2, the terminal receives the corresponding CSI configuration, and the CSI configuration signaling includes a CSI sub-configuration, and determines the symbol type corresponding to the sub-configuration based on the method of this embodiment. It is worth noting that if the symbol type associated with the CSI sub-configuration is an SBFD symbol, the terminal performs the corresponding CSI measurement on the SBFD symbol based on the sub-configuration, and reports the CSI result corresponding to the SBFD symbol based on the sub-configuration; correspondingly, if the symbol type associated with the CSI sub-configuration is a non-SBFD symbol, the terminal performs the corresponding CSI measurement on the non-SBFD symbol based on the sub-configuration, and reports the CSI result corresponding to the non-SBFD symbol based on the sub-configuration; the possible implementation method is the same as that of Example 1-2 and will not be repeated here.

[0493] In Example 2-3, the terminal receives the corresponding CSI configuration, the CSI configuration signaling includes a CSI sub-configuration, and based on the method of this embodiment, determines the CSI-RS resource associated with the sub-configuration. It is worth noting that in the corresponding scenario of this embodiment, the CSI-RS resource lists associated with different sub-configurations are exactly the same.

[0494] Possible implementations include:

[0495] In embodiment 1, a terminal determines, based on a CSI configuration, a CSI-RS resource set (CSI-RS resource set) associated with the configuration for channel measurement and / or for interference measurement. The terminal determines that the CSI-RS resources associated with the corresponding sub-configurations are identical. Furthermore, the resources included in the CSI-RS resource set associated with the CSI configuration for channel measurement and / or for interference measurement are identical.

[0496] Based on any of the above embodiments, the corresponding configuration parameters can be configured based on the sub-configuration, and different sub-configurations correspond to different configuration parameters. They can also be configured based on the CSI configuration, and different sub-configurations correspond to the same configuration parameters. The present invention does not limit this.

[0497] Exemplarily, considering that the base station may have different reporting types based on different SBFD symbol types, the corresponding report quantity may be configured based on different sub-configurations.

[0498] Exemplarily, considering that the DL frequency domain ranges corresponding to the SBFD symbol type and the non-SBFD symbol are different, the corresponding report frequency domain configuration (reportFreqConfiguration) can be configured based on the sub-report config. Exemplarily, if the first sub-configuration is associated with the SBFD symbol type, the corresponding report frequency domain configuration (reportFreqConfiguration) can be configured as subband; Exemplarily, if the second sub-configuration is associated with the non-SBFD symbol type, the corresponding reportFreqConfiguration can be configured as wideband;

[0499] The present invention mainly designs CSI configuration rules in corresponding SBFD scenarios, so as to enable the terminal to report SBFD and non-SBFD symbol types based on different configurations.
