Description

Signaling indication method and device, network side equipment and terminal

[0001] The present disclosure claims priority to the Chinese patent application No. 202411089559.6 entitled "Signaling indication method and device, network side equipment and terminal" filed on August 9, 2024 with the China Patent Office, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of communication, and particularly refers to a signaling indication method, device, network side equipment and terminal. BACKGROUND

[0003] In a communication system, for a terminal using carrier aggregation and in a radio resource control (RRC) connected state, the serving cells of the terminal include a primary cell (Pcell) and secondary cells (Scells). The primary cell of the terminal will always send synchronization signals and PBCH blocks (SSBs) so that the terminal can keep synchronization with the primary cell and establish a data communication link. The number of secondary cells can be large, and in order to save energy of the base station, a part of the secondary cells will also send SSBs so that the terminal can receive services from these secondary cells. For another part of the secondary cells, the base station will let them enter an energy saving state, in which these secondary cells do not send SSBs or send long period SSBs. When these energy saving secondary cells are needed to provide data transmission services to the terminal, these energy saving secondary cells will be instructed to send on-demand SSBs so that the terminal can complete random access and downlink fine synchronization based on the on-demand SSBs, and the terminal will also report measurement results of the on-demand SSBs so that the base station can select appropriate secondary cells to activate the energy saving secondary cells.

[0004] Channel state information (CSI) reporting is an important reporting approach, which is used for a terminal to report CSI measurement results to a base station. According to the current CSI framework, the terminal is currently allowed to report measurement results of at most one carrier in each reporting triggered by a downlink control information (DCI) sent by the base station, and can only report measurement results of normal SSBs.

[0005] In the SCell activation and on-demand SSB sending process, the number of configured SCells to be activated is multiple. According to the current CSI framework, the terminal needs to report the on-demand SSB measurement results on multiple SCells to the base station multiple times, resulting in a high delay in reporting the on-demand SSB measurement of the SCell to be activated, which may cause a large SCell activation delay. SUMMARY

[0006] The purpose of the present disclosure is to provide a signaling indication method and device, a network side device and a terminal, to solve the problem of high delay in reporting the measurement of the on-demand signal of the energy-saving secondary cell in the related art.

[0187] In at least one embodiment of the disclosure, the CRC of the first DCI is scrambled by a new Radio Network Temporary Identifier (RNTI) to indicate that the first DCI is used to trigger semi-persistent reporting of the first object.

[0188] In a case where the CRC of the first DCI is scrambled by the first RNTI, the first DCI is used to trigger CSI reporting associated with the first object.

[0189] The first RNTI is an RNTI for the first object, or the first RNTI is a network energy savings (NES)-RNTI. In some embodiments, the NES-RNTI is different from an existing SP-CSI-RNTI.

[0190] The embodiments of the present disclosure introduce a new first RNTI for the first object, and the CRC of the first DCI is scrambled by the first RNTI; the first RNTI is used to indicate that the first DCI is used to trigger CSI reporting for the first object.

[0191] In some embodiments, in the case that the CRC of the first DCI is scrambled by the first RNTI, the trigger state information corresponding to the first DCI is trigger state information for the first object.

[0192] In at least one embodiment of the present disclosure, the first trigger state list information includes at least one trigger state information; wherein the trigger state information includes:

[0193] A plurality of first CSI reporting configuration identification numbers, the first CSI reporting configuration identification numbers being associated with at least the first object;

[0194] Or,

[0195] At least one first CSI reporting configuration identification number list, the first CSI reporting configuration identification number list being associated with at least the first object.

[0196] Or,

[0197] At least one first reporting configuration information, the first reporting configuration information being associated with at least the first object.

[0198] In the embodiments of the present disclosure, the first trigger state list information is used to configure a trigger state list for a terminal to semi-persistently report CSI in L1 (Layer 1), which contains measurement information of a plurality of first objects, such as measurement information of 32 first objects.

[0199] For example, the first CSI reporting configuration identification number described above can be configured up to 32 to support the reporting of measurement results of on-demand SSBs of 32 secondary cells.

[0200] For another example, the first CSI reporting configuration identification number list described above can be configured up to 32 first CSI reporting configuration identification numbers to support the reporting of measurement results of on-demand SSBs of up to 32 secondary cells.

[0201] Each first CSI reporting configuration identification number list includes N first CSI reporting configuration identification numbers; N is an integer;

[0202] Alternatively, the CSI reporting configuration indicated by the first CSI reporting configuration identification number comprises a CSI reporting configuration including the first object.

[0203] It should be noted that the maximum value of N is consistent with the maximum value of the number of secondary cells configured by the network. For example, the maximum value of the number of secondary cells configured by the network to the terminal is 32, and the maximum value of N is 32, that is, each first CSI reporting configuration identification number corresponds to one secondary cell to be activated which has been configured.

[0204] In some embodiments, the method further comprises:

[0205] The network side device configures, for the terminal, a correspondence between an index number of the first CSI reporting configuration identification number list and at least one first CSI reporting configuration identification number by a first manner; wherein the first manner comprises at least one of predefinition, pre-configuration, and semi-static signaling configuration.

[0206] Correspondingly, the terminal can determine the first CSI reporting configuration identification number based on the index number of the first CSI reporting configuration identification number list according to the correspondence between the index number of the first CSI reporting configuration identification number list and at least one first CSI reporting configuration identification number configured by the network side device.

[0207] In at least one embodiment of the present disclosure, the method further comprises:

[0208] The network side device configures, for the terminal, reporting priorities of the plurality of CSIs indicated by the trigger state information indication by a second manner; wherein

[0209] The plurality of CSIs comprises at least two of the CSI associated with the first object, the CSI associated with the L1 / L2 triggered mobility (LTM), and the CSI associated with the multiple-input multiple-output (MIMO).

[0210] The second manner comprises at least one of predefinition, pre-configuration, and semi-static signaling configuration.

[0211] In some embodiments, the CSI reporting with high priority will be preferentially semi-persistently reported by the terminal through the PUSCH.

[0212] The priorities of the plurality of CSIs from high to low are:

[0213] The CSI associated with the LTM, the CSI associated with the first object, and the CSI associated with the MIMO.

[0214] For example, when the CSI reporting associated with the LTM is configured, the terminal preferentially reports the CSI reporting associated with the LTM.

[0215] To sum up, in the embodiments of the present disclosure, the network side device triggers the CSI reporting associated with the on-demand SSB and / or the on-demand TRS through the first DCI, and / or the network side device indicates the trigger state information associated with the on-demand SSB and / or the on-demand TRS through the first trigger state list information; the terminal determines whether to report the measurement result applicable to the on-demand SSB and / or the on-demand TRS to the network side device based on the received first DCI and / or the first trigger state list information, solves the reporting trigger problem of the measurement result of the on-demand SSB and / or the on-demand TRS of multiple secondary cells, and enables the base station to select and activate a suitable secondary cell according to the received measurement result of the on-demand SSB, thereby improving the quality and efficiency of the secondary cell activation, and further reducing the energy consumption of the network side device.

[0216] As shown in FIG. 2, the embodiments of the present disclosure further provide a signaling indication method, which comprises:

[0217] Step 201, the terminal receives the first DCI sent by the network side device, or receives the first trigger state list information sent or configured by the network side device.

[0218] The first DCI is used to trigger the channel state information (CSI) reporting associated with the first object; or the first trigger state list information is used to indicate the trigger state information associated with the first object.

[0219] The first object is the on-demand SSB and / or the on-demand TRS.

[0220] In some embodiments, the trigger state information associated with the first object is used to indicate the trigger state of the first object.

[0221] It should be noted that the first trigger state list information sent by the network side device mentioned in the embodiments of the present disclosure can be understood as that the network side device sends the first trigger state list information to the terminal through a separate signaling; and the first trigger state list information configured by the network side device can be understood as that the network side device configures the first trigger state list information to the terminal through a radio resource control (RRC) configuration signaling; which is not limited here.

[0222] In the embodiments of the present disclosure, the network side device triggers the CSI reporting associated with the on-demand SSB and / or the on-demand TRS through the first DCI, and / or the network side device indicates the trigger state information associated with the on-demand SSB and / or the on-demand TRS through the first trigger state list information; the terminal determines whether to report the measurement result applicable to the on-demand SSB and / or the on-demand TRS to the network side device based on the received first DCI and / or the first trigger state list information, solves the reporting trigger problem of the measurement result of the on-demand SSB and / or the on-demand TRS of the plurality of secondary cells, and enables the base station to select and activate a suitable secondary cell according to the received measurement result of the on-demand SSB, thereby improving the quality and efficiency of the secondary cell activation, and further reducing the energy consumption of the network side device.

[0223] In some embodiments, the method further comprises:

[0227] Alternatively,

[0228] The terminal reports the CSI associated with the first object to the network side device according to the first DCI and the first trigger state list information.

[0229] In some embodiments, the first DCI is used to trigger the CSI reporting associated with the first object, comprising:

[0232] In some embodiments, the non-periodic reporting manner based on the PUSCH can be understood as: the terminal reports through the PUSCH, and the first DCI triggers once, and only one PUSCH is reported.

[0233] In at least one embodiment of the present disclosure, a first field of the first DCI is used to trigger the CSI reporting associated with the first object.

[0234] and / or, the first field of the first DCI is a CSI request field;

[0235] and / or, the second field of the first DCI is used to indicate whether the first DCI triggers the CSI reporting associated with the first object,

[0236] and / or, the second field of the first DCI is a reserved bit of the first DCI.

[0237] In some embodiments, the second field is a transform precoder indicator.

[0238] In one implementation, the first field is multiplexed with a CSI request field, and the first field is used to trigger a PUSCH-based semi-persistent CSI reporting including measurement results of the first object.

[0239] In another implementation, the second field is a reserved bit (e.g., a transform precoder indicator) of the first DCI, and the second field is used to indicate whether the first DCI triggers the semi-persistent CSI reporting for the first object.

[0240] In some embodiments, in a case where the second field indicates that the first DCI triggers the CSI reporting associated with the first object, the trigger state information corresponding to the first DCI is trigger state information for the first object.

[0241] and / or,

[0242] In a case where the second field indicates that the first DCI does not trigger the CSI reporting associated with the first object, the trigger state information corresponding to the first DCI is trigger state information for a signal other than the first object.

[0243] In some embodiments, the second field indicating that the first DCI does not trigger the CSI reporting associated with the first object can also be understood as: the second field indicates that the first DCI triggers the semi-persistent CSI reporting for a signal other than the first object.

[0244] In some embodiments, a cyclic redundancy check code (CRC) of the first DCI is scrambled by a semi-persistent channel state information radio network temporary identifier (SP-CSI-RNTI).

[0245] and / or, the first DCI is of a DCI format 0_1 or a DCI format 0_2.

[0246] In at least one embodiment of the present disclosure, the CRC of the first DCI is scrambled by a new RNTI, which is used to indicate that the first DCI is used to trigger the semi-persistent reporting of the first object; specifically:

[0247] In the case that the CRC of the first DCI is scrambled by the first RNTI, the first DCI is used to trigger the CSI reporting associated with the first object.

[0248] Wherein, the first RNTI is an RNTI for the first object; and / or, the first RNTI is a network energy saving NES-RNTI. In some embodiments, the NES-RNTI is different from the existing SP-CSI-RNTI.

[0249] Embodiments of the present disclosure introduce a new first RNTI for the first object, and the CRC of the first DCI is scrambled by the first RNTI; the first RNTI is used to indicate that the first DCI is used to trigger the CSI reporting for the first object.

[0250] In at least one embodiment of the present disclosure, the first trigger state list information includes at least one trigger state information; wherein, the trigger state information includes:

[0251] A plurality of first CSI reporting configuration identification numbers, the first CSI reporting configuration identification numbers are associated with at least the first object;

[0252] Or,

[0253] At least one first CSI reporting configuration identification number list, the first CSI reporting configuration identification number list is associated with at least the first object.

[0254] Or,

[0255] At least one first reporting configuration information, the first reporting configuration information is associated with at least the first object.

[0256] In embodiments of the present disclosure, the first trigger state list information is used to configure a trigger state list for the terminal to semi-persistently report CSI in L1 (Layer 1), which contains the measurement information of a plurality of first objects, such as the measurement information of 32 first objects.

[0257] For example, the first CSI reporting configuration identification number described above can be configured up to 32 to support the reporting of the measurement results of the on-demand SSB of up to 32 secondary cells.

[0258] For another example, the first CSI reporting configuration identification number list described above can be configured up to 32 first CSI reporting configuration identification numbers to support the reporting of the measurement results of the on-demand SSB of up to 32 secondary cells.

[0259] Each first CSI reporting configuration identification number list includes N first CSI reporting configuration identification numbers; N is an integer;

[0260] Alternatively, the CSI reporting configuration indicated by the first CSI reporting configuration identification number includes the CSI reporting configuration of the first object.

[0261] It should be noted that the maximum value of N is consistent with the maximum value of the number of configured secondary cells. For example, the maximum value of the number of secondary cells configured by the network to the terminal is 32, and the maximum value of N is 32, that is, each first CSI reporting configuration identification number corresponds to one configured secondary cell to be activated.

[0262] In some embodiments, the method further comprises:

[0263] The terminal receives the correspondence between the index number of the first CSI reporting configuration identification number list configured by the network side device through the first mode and the at least one first CSI reporting configuration identification number; wherein the first mode includes at least one of predefinition, pre-configuration, and semi-static signaling configuration; the first CSI reporting configuration identification number list includes N first CSI reporting configuration identification numbers; N is an integer.

[0264] Correspondingly, the terminal can determine the first CSI reporting configuration identification number based on the index number of the first CSI reporting configuration identification number list according to the correspondence between the index number of the first CSI reporting configuration identification number list configured by the network side device and the at least one first CSI reporting configuration identification number.

[0265] In at least one embodiment of the present disclosure, the method further comprises:

[0266] The terminal receives the reporting priority of the plurality of CSIs indicated by the trigger state information configured by the network side device through the second mode; wherein,

[0267] The plurality of CSIs includes at least two of the CSI associated with the first object, the CSI associated with the layer 1 / layer 2 triggered mobility LTM, and the CSI associated with the multiple-input multiple-output MIMO.

[0268] The second mode includes at least one of predefinition, pre-configuration, and semi-static signaling configuration; and the first trigger state list information includes at least one trigger state information.

[0269] The priority of the plurality of CSIs from high to low is:

[0270] The CSI associated with the LTM, the CSI associated with the first object, and the CSI associated with the MIMO.

[0271] In some embodiments, the method further comprises:

[0272] The terminal preferentially reports the CSI with the highest priority.

[0273] In the case where the terminal capability supports and the reported channel capacity is sufficient, after the terminal completes the reporting of the CSI with the highest priority, the terminal continues to report the CSI with a lower priority.

[0274] For example, when the CSI reporting associated with the LTM is configured, the terminal preferentially reports the CSI reporting associated with the LTM.

[0275] In summary, in the embodiments of the present disclosure, the network side device triggers the CSI reporting associated with the on-demand SSB and / or the on-demand TRS through the first DCI, and / or the network side device indicates the trigger state information associated with the on-demand SSB and / or the on-demand TRS through the first trigger state list information; the terminal determines whether to report the measurement result applicable to the on-demand SSB and / or the on-demand TRS to the network side device based on the received first DCI and / or the first trigger state list information, which solves the reporting trigger problem of the measurement result of the on-demand SSB and / or the on-demand TRS of multiple secondary cells, so that the base station can select and activate a suitable secondary cell according to the received measurement result of the on-demand SSB, thereby improving the quality and efficiency of the secondary cell activation, and further reducing the energy consumption of the network side device.

[0276] In order to more clearly describe the signaling indication method provided by the embodiments of the present disclosure, several examples are described below.

[0277] Example one

[0278] The network side device triggers the terminal to report the CSI associated with the first object (such as the on-demand SSB) in a semi-persistent reporting manner based on PUSCH using the first DCI.

[0279] The first DCI uses a reserved bit Transform precoder indicator to indicate that the first DCI is used to trigger the semi-persistent reporting of the first object, and a first field in the first DCI is used to trigger the CSI reporting of the first object based on PUSCH. Specifically:

[0280] The first field in the first DCI is used to trigger the semi-persistent CSI reporting based on PUSCH, and the CSI reporting includes the measurement result of the first object. The first field multiplexes the CSI request field.

[0281] The second field in the first DCI is used to indicate whether the first DCI triggers the semi-persistent CSI reporting for the first object. The second field in the first DCI is a reserved bit Transform precoder indicator.

[0282] When the second field in the first DCI indicates that the first DCI triggers the semi-persistent CSI reporting for the first object, the trigger state corresponding to the DCI is the trigger state for the first object.

[0283] When the second field in the first DCI indicates that the first DCI triggers the semi-persistent CSI reporting for the signal other than the first object, the trigger state corresponding to the DCI is the trigger state for the signal other than the first object.

[0284] The CRC of the first DCI is scrambled by the SP-CSI-RNTI.

[0285] The first DCI is DCI format 0_1 or DCI format 0_2.

[0286] In this example, in order to determine the secondary cell that needs to be activated, the network side device instructs multiple secondary cells to send on-demand SSB. The reason for sending on-demand SSB instead of normal SSB is to save network energy. The terminal measures the on-demand SSB sent by the secondary cell according to the indication signaling of the measurement reporting configuration sent by the network, and reports the measurement result of the on-demand SSB to the base station. Then, the base station will select and activate the appropriate secondary cell according to the measurement result.

[0287] In order to instruct the terminal to report the measurement result of the on-demand SSB, the network side device sends a first DCI to trigger the terminal to send a PUSCH-based CSI report, and the CSI report contains the measurement result of the on-demand SSB. As shown in Table 1, the first DCI contains the following information. The CRC of the first DCI is scrambled by the SP-CSI-RNTI, so that the network side device can indicate the purpose and destination of the first DCI to the terminal through the scrambled RNTI. The size of the first field in the first DCI, that is, the number of bits occupied by the first field, is indicated by the higher layer signaling, which contains at most 6 bits, that is, the first field may occupy 0-6 bits. The first field multiplexes the CSI request field. Even if the first DCI is scrambled by the SP-CSI-RNTI, the first DCI can be used for CSI reporting for MIMO or for on-demand SSB, so the second field in the first DCI is used to indicate whether the DCI triggers the CSI reporting for the on-demand SSB. When the CRC of the first DCI is scrambled by the SP-CSI-RNTI, the transform precoder indicator of the first DCI is a reserved bit, which can be used for other purposes, so the second field in the first DCI can be the transform precoder indicator. When the second field in the first DCI indicates that the DCI triggers the semi-persistent CSI reporting for the first object, the trigger state corresponding to the DCI is the trigger state for the first object. When the second field in the first DCI indicates that the DCI triggers the semi-persistent CSI reporting for other signals (that is, signals other than the first object), the trigger state corresponding to the DCI is the trigger state for the other signals. In some embodiments, the first DCI is a DCI format 0_1 or a DCI format 0_2.

[0288] Table 1

[0289] In this example, the network side device triggers the terminal to report the measurement result of the on-demand SSB through the first DCI, the first DCI is scrambled by the SP-CSI-RNTI, and the second field in the first DCI is used to indicate whether the DCI triggers the CSI reporting for the on-demand SSB. Then the terminal can be instructed to report the measurement result of the on-demand SSB through the DCI, which solves the problem of dynamic triggering and reporting of the measurement result of the on-demand SSB of the secondary cell, so that the base station can select and activate a suitable secondary cell according to the received measurement result of the on-demand SSB, thereby improving the quality and efficiency of the secondary cell activation, and further improving the data transmission rate of the first terminal and reducing the energy consumption of the base station.

[0290] Example two

[0291] The network-side device triggers the terminal to report the CSI associated with the first object (such as on-demand SSB) in a PUSCH-based semi-persistent reporting manner using the first DCI.

[0292] A new first RNTI for the first object is introduced, and the CRC of the first DCI is scrambled using the first RNTI to indicate that the DCI is used to trigger the CSI reporting for the first object.

[0293] In this example, the CRC of the first DCI is scrambled using the new RNTI to indicate that the DCI is used to trigger the semi-persistent reporting of the on-demand SSB.

[0294] A new first RNTI for the first object is introduced, and the CRC of the first DCI is scrambled using the first RNTI.

[0295] The first RNTI is used to indicate that the DCI is used to trigger the CSI reporting for the first object.

[0296] The first RNTI is NES-RNTI, which is different from the existing SP-CSI-RNTI.

[0297] When the CRC of the first DCI is scrambled using the first RNTI, the trigger state corresponding to the DCI is the trigger state for the first object.

[0298] In this example, the network-side device indicates multiple secondary cells to send on-demand SSBs in order to determine the secondary cells that need to be activated. The reason for sending on-demand SSBs instead of normal SSBs is to save network energy. The terminal measures the on-demand SSBs sent by the secondary cells according to the indication signaling of the measurement reporting configuration sent by the network, and reports the measurement results of the on-demand SSBs to the base station. Then, the base station selects appropriate secondary cells to be activated according to the measurement results.

[0299] The signaling indication method shown in FIG. 3 includes:

[0300] Step 31, the primary cell indicates the secondary cell to send an on-demand SSB;

[0301] Step 32, the secondary cell sends an on-demand SSB;

[0302] Step 33, the primary cell scrambles the CRC of the first DCI using the NES-RNTI;

[0303] Step 34, the primary cell sends a first DCI to the first terminal, triggering the first terminal to send a PUSCH-based CSI report. The CSI report contains measurement results of the on-demand SSB. The CRC of the first DCI is scrambled by the NES-RNTI. When the CRC of the first DCI is scrambled by the NES-RNTI, the trigger state corresponding to the first DCI is the trigger state for the first object. In this way, the primary cell can indicate to the terminal through the scrambled RNTI that the first DCI is used to trigger the CSI report for the on-demand SSB.

[0304] Step 35, the first terminal completes downlink fine synchronization and performs CSI measurement according to the on-demand SSB.

[0305] Step 36, the first terminal reports the measurement results of the on-demand SSB to the primary node based on PUSCH.

[0306] In this example, the network side device triggers the terminal to report the measurement results of the on-demand SSB through the first DCI. The first DCI is scrambled by the NES-RNTI, which is used to indicate that the DCI triggers the CSI report for the on-demand SSB. Therefore, the terminal can be instructed to report the measurement results of the on-demand SSB through the first DCI, solving the problem of dynamic triggering and reporting of the measurement results of the on-demand SSB of the secondary cell. The network side device can select and activate a suitable secondary cell according to the received measurement results of the on-demand SSB, thereby improving the quality and efficiency of the activation of the secondary cell, and further improving the data transmission rate of the first terminal and reducing the energy consumption of the base station.

[0307] Example Three

[0308] The network side device uses the first trigger state list information to indicate the trigger state information for the first object to the terminal. The first trigger state list information includes one or more trigger state information. The trigger state information contains a plurality of first CSI reporting configuration identification numbers for the first object, or the trigger state information contains at least one first CSI reporting configuration identification number list for the first object.

[0309] For example, up to 32 new reporting configuration information for the on-demand SSB is added in the trigger state information. Specifically,

[0310] The first trigger state list information is used to configure a trigger state list for the terminal to semi-persistently report channel state information (CSI) in L1, which contains up to 32 measurement information of the first object.

[0311] The first trigger state list information includes at least one trigger state information, and the trigger state information includes at least one and at most 32 CSI reporting configuration identification numbers for the first object, or at least one CSI reporting configuration identification number list for the first object;

[0312] The CSI reporting configuration identification number list for the first object includes at least one and at most 32 CSI reporting configuration identification numbers.

[0313] At least one CSI reporting configuration identification number in the CSI reporting configuration identification number list for the first object corresponds to the reporting configuration of the first object.

[0314] The correspondence between the CSI reporting configuration identification number list index number and the at least one CSI reporting configuration identification number is configured by a predefinition, preconfiguration or semi-static signaling configuration.

[0315] The first trigger state list information refers to a CSI semi-persistent trigger state list on PUSCH (CSI-SemiPersistentOnPUSCH-TriggerStateList).

[0316] The trigger state information refers to a CSI semi-persistent trigger state on PUSCH (CSI-SemiPersistentOnPUSCH-TriggerState).

[0317] In this example, the network side device indicates a plurality of secondary cells to send on-demand SSBs in order to determine the secondary cells that need to be activated. The reason for sending on-demand SSBs instead of normal SSBs is to save network energy. The terminal measures the on-demand SSBs sent by the secondary cells according to the indication signaling of the measurement reporting configuration sent by the network, and reports the measurement results of the on-demand SSBs to the base station. Then, the base station will select and activate appropriate secondary cells according to the measurement results.

[0318] As shown in Table 2, Table 3, and Table 4, the first trigger state list (i.e., the CSI semi-persistent trigger state list on PUSCH) is used to configure the UE with a trigger state list for semi-persistent reporting of channel state information in L1; the first trigger state list contains 4 first trigger states (i.e., CSI semi-persistent trigger states #1-#4 on PUSCH). As shown in Table 2, the CSI semi-persistent trigger states on PUSCH contain 4 CSI reporting configuration identifiers (i.e., CSI reporting configurations #1-#4), which correspond to the on-demand SSB reporting configuration and are used to indicate the on-demand SSB reporting configuration information. As shown in Table 3, the CSI semi-persistent trigger states on PUSCH contain 1 CSI reporting configuration identifier list for a first object; the CSI reporting configuration identifier list for a first object contains 2 CSI reporting configuration identifiers; at least one CSI reporting configuration identifier in the CSI reporting configuration identifier list for a first object corresponds to the reporting configuration of a first object. As shown in Table 4, the correspondence between the CSI reporting configuration identifier list index and the 2 CSI reporting configuration identifiers is configured by RRC signaling.

[0319] Table 2

[0320] Table 3

[0321] Table 4

[0322] In this example, the network-side device configures the terminal with trigger states through the first trigger state list information to semi-persistently report CSI in L1, so that the terminal can report the measurement results of the on-demand SSB through the trigger states, thereby solving the problem of reporting configuration of the measurement results of the on-demand SSB of the secondary cell, enabling the base station to select and activate a suitable secondary cell according to the received measurement results of the on-demand SSB, thereby improving the quality and efficiency of secondary cell activation, and further improving the data transmission rate of the first terminal and reducing the energy consumption of the base station.

[0323] Example Four

[0324] The network-side device indicates the trigger state information of a first object to the terminal using the first trigger state list information. Specifically, the priority of the CSI reporting associated with the on-demand SSB, the CSI reporting associated with the LTM, and the semi-persistent CSI reporting associated with the MIMO in the first trigger state list information is configured by predefinition, pre-configuration, or semi-static signaling configuration.

[0325] The priority of the CSI reporting associated with the on-demand SSB, the CSI reporting associated with the LTM, and the semi-persistent CSI reporting associated with the MIMO in the first trigger state list is configured by predefinition, pre-configuration, or semi-static signaling configuration.

[0326] The CSI reporting with high priority is reported by the terminal through the PUSCH in priority.

[0327] The priority of the default semi-persistent reporting is in descending order: the priority of the CSI reporting associated with the LTM is the highest, the priority of the CSI reporting associated with the on-demand SSB is the second, and the priority of the CSI reporting associated with the MIMO is the lowest. When the CSI reporting associated with the LTM is configured, the CSI reporting associated with the LTM is reported in priority.

[0328] In some embodiments, the first trigger state list information not only contains the CSI reporting configuration information associated with the on-demand SSB, but also contains the reporting configuration information associated with the LTM and the reporting configuration information associated with the MIMO. At this time, considering the capacity of the PUSCH and the processing capability of the terminal, the priority order of the semi-persistent reporting between these reporting configuration information needs to be defined, so that the terminal selects the appropriate CSI for reporting according to the priority.

[0329] When the CSI semi-persistent trigger state #1 on the PUSCH contains the CSI reporting configuration associated with the on-demand SSB, the CSI reporting configuration associated with the LTM, and the CSI reporting configuration associated with the MIMO, the priority of the CSI reporting associated with the on-demand SSB, the CSI reporting associated with the LTM, and the CSI reporting associated with the MIMO in the first trigger state is configured by predefinition, pre-configuration, or semi-static signaling configuration. The CSI reporting with high priority is reported by the terminal in priority. The priority of the default semi-persistent reporting is in descending order: the priority of the CSI reporting associated with the LTM is the highest, the priority of the CSI reporting associated with the on-demand SSB is the second, and the priority of the CSI reporting associated with the MIMO is the lowest. When the CSI reporting associated with the LTM is configured, the CSI reporting associated with the LTM is reported in priority. As shown in Table 5, since the CSI semi-persistent trigger state #1 on the PUSCH contains the CSI reporting configuration associated with the LTM, the terminal reports the CSI information associated with the LTM in priority.

[0330] Table 5

[0331] In the example, the network side device configures the trigger state for the terminal through the first trigger state list information, and defines the priority order of the semi-persistent reporting between the reporting configuration information, so that the terminal selects the appropriate CSI for reporting according to the priority, solves the priority problem of multiple CSI semi-persistent reporting, and also takes into account the capacity of PUSCH and the processing capability of the terminal.

[0332] Example five

[0333] The semi-persistent reporting mechanism of the on-demand SSB measurement result based on PUSCH is suitable for the terminal to semi-persistently report the measurement result of the on-demand SSB through PUSCH, and the complete process is as follows:

[0334] The base station first configures the terminal to semi-persistently report the first trigger state list information of the on-demand SSB through RRC signaling, and the list information contains up to 64 trigger states, and each trigger state contains up to 32 reporting configurations of the on-demand SSB. Then the terminal is triggered to semi-persistently report the measurement result of the on-demand SSB through the first DCI, and the 6 bits in the first DCI will indicate the specific reporting trigger state of the on-demand SSB in the 64 trigger states through mapping. Once the network side device issues the trigger first DCI to the terminal, the terminal reports the measurement result of the on-demand SSB according to the on-demand SSB reporting configuration in the trigger state corresponding to the first DCI configured in the previous RRC signaling.

[0335] In summary, in the embodiment of the disclosure, the network side device triggers the CSI reporting associated with the on-demand SSB and / or on-demand TRS through the first DCI, and / or the network side device indicates the trigger state information associated with the on-demand SSB and / or on-demand TRS through the first trigger state list information; the terminal determines whether to report the measurement result suitable for the on-demand SSB and / or on-demand TRS to the network side device based on the received first DCI and / or first trigger state list information, solves the reporting trigger problem of the measurement result of the on-demand SSB and / or on-demand TRS of multiple secondary cells, so that the base station can select to activate the appropriate secondary cell according to the received measurement result of the on-demand SSB, improves the quality and efficiency of the secondary cell activation, and further reduces the energy consumption of the network side device.
