For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0070] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0071] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0072] This disclosure provides an information determination method and apparatus to ensure the accuracy of terminal measurements.

[0073] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0074] Referring to Figure 1, which is a flowchart of an information determination method provided in an embodiment of this disclosure, applied to a terminal, as shown in Figure 1, it includes the following steps:

[0075] Step 101: Determine the TCI State of the non-periodic layer 1 cross-interference measurement resource based on at least one of the following methods: protocol specification; first indication of network equipment (such as base station).

[0076] The aperiodic layer 1 cross-interference measurement resources include: resources for measuring received RSSI, and / or resources for measuring SRS-RSRP, wherein the TCI state contains quasi-co-located QCL information.

[0077] The resource used to measure RSSI can be aperiodic (AP) L1 cross-link interference (CLI)-RSSI (AP L1 CLI-RSSI), and the resource used to measure SRS-RSRP can be AP L1 CLI-SRS-RSRP.

[0078] The method for determining the TCI State of non-periodic layer 1 cross-interference measurement resources can be applied to one or more of the following cases:

[0079] The first case is that the interval between the last symbol of the PDCCH carrying the trigger DCI and the first symbol of the triggered aperiodic layer 1 cross-interference measurement resource is less than the beam switching time reported by the terminal. Here, the trigger DCI is the DCI carrying trigger status information.

[0080] The second scenario: The terminal is configured with a downlink TCI list or a combined TCI list that includes multiple TCI states before applying an indicated TCI state.

[0081] In the first scenario, the protocol specifies or the first indication indicates that the terminal assumes the triggered aperiodic L1 crosstalk measurement resource is quasi-co-located with one of the following channels, signals, or measurement resources, with the quasi-co-location type being type D:

[0082] One of the most recently received PDSCH and the most recently monitored CORESET by the terminal; or, one of the most recently received PDSCH, the most recently monitored CORESET, and the most recently received CSI reference signal CSI-RS by the terminal; or,

[0083] The protocol specifies, or the first indication is used to instruct, that the terminal applies the indicated TCI State to the aperiodic L1 cross-interference measurement resources; or,

[0084] The protocol specifies, or the network device indicates, that if the target channel, target signal, or target measurement resource has the indicated TCI State, the terminal applies the quasi-co-address assumption of the target channel, target signal, or target measurement resource to the triggered aperiodic L1 cross-interference measurement resource; otherwise, one of the following quasi-co-address information is applied to the triggered aperiodic L1 cross-interference measurement resource:

[0085] Quasi-co-address information of one of the most recently received PDSCH and the most recently monitored CORESET of the terminal;

[0086] Quasi-co-address information of one of the terminal’s most recently received PDSCH, most recently monitored CORESET, and most recently received CSI reference signal CSI-RS;

[0087] The indicated TCI state;

[0088] Quasi-co-address information for the first CORESET;

[0089] Wherein, the target channel or target signal or target measurement resource and the triggered aperiodic L1 cross-interference measurement resource are located on the same symbol; the first CORESET is the CORESET with the smallest control resource set ID (controlResourceSetId) in the most recent time slot monitored by one or more CORESETs in the active BWP of the serving cell.

[0090] In the above description, "nearest" can be understood as the time slot or moment that is closest to the time domain location of the measurement resource.

[0091] The target channel, target signal, or target measurement resource includes at least one of the following:

[0092] The scheduled PDSCH has an offset greater than or equal to the threshold value timeDurationForQCL reported by the terminal. The threshold value defines the minimum number of OFDM symbols required for the terminal to receive the PDCCH and apply the quasi-co-address information received in the DCI to the PDSCH processing. The DCI is the DCI carried in the PDCCH received by the terminal.

[0093] Aperiodic CSI, wherein the scheduling offset of the aperiodic CSI is greater than or equal to the beam switching time reported by the terminal;

[0094] Periodic CSI;

[0095] Semi-continuous CSI;

[0096] Non-periodic L1 CLI-RSSI or L1 CLI-SRS-RSRP measurement resources, wherein the offset of the non-periodic L1 CLI-RSSI or L1 CLI-SRS-RSRP measurement resource scheduling is greater than or equal to the beam switching time reported by the terminal.

[0097] Periodic L1 CLI-RSSI or L1 CLI-SRS-RSRP measurement resources;

[0098] Semi-continuous L1 CLI-RSSI or L1 CLI-SRS-RSRP measurement resources.

[0099] Here, "offset" refers to the interval between the last symbol of the PDCCH carrying the trigger DCI and the first symbol of the trigger aperiodic layer 1 cross-interference measurement resource.

[0100] In the process of determining the TCI State of the aperiodic L1 cross-interference measurement resource, if the quasi-co-location information of the first CORESET is applied to the triggered aperiodic L1 cross-interference measurement resource, the terminal may also receive the downlink or joint TCI State list (dl-OrJointTCI-StateList) configured by the network device, and receive the TCI State indicated by the network device, wherein the indicated TCI State is associated with the PCI of other cells, and the other cells are different from the serving cell.

[0101] In the process of determining the TCI State of the non-periodic layer 1 cross-interference measurement resources, if the indicated TCI State is applied to the L1 cross-interference measurement resources, the terminal may also receive the dl-OrJointTCI-StateList configured by the network device, and receive the TCI State indicated by the network device, wherein the indicated TCI State is associated with the PCI of the serving cell.

[0102] In some embodiments, if the interval between the last symbol of the physical downlink control channel (PDCCH) carrying triggering downlink control information (DCI) and the first symbol of the triggered aperiodic L1 cross-interference measurement resource is greater than or equal to the beam switching time reported by the terminal, the TCI State of the triggered aperiodic L1 cross-interference measurement resource is: the TCI State of the aperiodic L1 cross-interference measurement resource configured by the network device.

[0103] In the second scenario, the protocol specifies or the first indication indicates that the triggered aperiodic L1 crosstalk measurement resource is quasi-co-located with one of the following resources, channels, or signals:

[0104] SSBs identified during random access;

[0105] SSB or CSI-RS resources identified during random access triggered by the synchronization reconfiguration process;

[0106] One of the most recently received PDSCH and the most recently monitored CORESET;

[0107] One of the most recently received PDSCH, the most recently monitored CORESET, and the most recently received CSI-RS;

[0108] Alternatively, the protocol specifies that the TCI State of the triggered aperiodic L1 cross-interference measurement resource is the TCI State with the lowest or highest ID among the TCI States configured by the network device.

[0109] In the above description, "nearest" can be understood as the time slot or moment that is closest to the time domain location of the measurement resource.

[0110] Based on the different situations mentioned above, the terminal can determine the TCI State of the non-periodic layer 1 cross-interference measurement resources according to the protocol or the instructions of the network device.

[0111] For example, in the first scenario, the terminal receives a trigger DCI, which includes a CSI request field. This CSI request field indicates the aperiodic L1-CLI trigger state. The L1-CLI trigger state is associated with one or more AP L1CLI-RSSI / CLI-SRS-RSRP measurement resources, and the temporal location of these AP L1 CLI-RSSI / CLI-SRS-RSRP measurement resources is configured via Radio Resource Control (RRC).

[0112] If the interval between the last symbol of the PDCCH carrying the trigger DCI and the first symbol of the triggered AP L1 CLI-RSSI / CLI-SRS-RSRP measurement resource is greater than or equal to the beam switching time reported by the terminal, for the TCI State of the triggered AP L1 CLI-RSSI / CLI-SRS-RSRP measurement resource, the terminal applies the TCI state of the AP L1 CLI-RSSI / CLI-SRS-RSRP measurement resource configured by the network device.

[0113] If the interval between the last symbol of the PDCCH carrying the trigger DCI and the first symbol of the triggered AP L1 CLI-RSSI / CLI-SRS-RSRP measurement resource is less than the beam switching time reported by the terminal, when the terminal measures the AP L1 CLI-RSSI / CLI-SRS-RSRP measurement resource:

[0114] The terminal assumes that the AP L1 CLI-RSSI / CLI-SRS-RSRP measurement resource is quasi-co-located with one of the following channels, resources, signals, or measurement resources, with the quasi-co-location type being type D: one of the terminal's most recently received PDSCH and the most recently monitored CORESET; or, one of the terminal's most recently received PDSCH, the most recently monitored CORESET, and the most recently received CSI-RS. Accordingly, the terminal applies one of the QCL assumptions of the most recently received PDSCH and the most recently monitored CORESET; or, the terminal applies one of the QCL assumptions of the most recently received PDSCH, the most recently monitored CORESET, and the most recently received CSI-RS. Alternatively,

[0115] The TCI state indicated by the terminal application can optionally be the TCI state indicated by the application when the network device has configured a dl-OrJointTCI-StateList for the terminal and the indicated TCI state is associated with the serving cell (the indicated TCI state is associated with the PCI of the serving cell). Alternatively,

[0116] The terminal determines whether there are other channels, signals, or measurement resources with indicated TCI states on the same symbol as the triggered AP L1 CLI-RSSI / CLI-SRS-RSRP measurement resource. If so, the terminal applies the QCL assumption of the other channel, signal, or measurement resource, which refers to the aforementioned target channel, target signal, or target measurement resource. If not, the terminal applies one of the QCL assumptions of the most recently received PDSCH and the most recently monitored CORESET, or one of the QCL assumptions of the most recently received PDSCH, the most recently monitored CORESET, and the most recently received CSI-RS, or the terminal applies the QCL assumption of the first CORESET, which is the CORESET with the smallest controlResourceSetId in the associated monitoring search space among the most recently monitored slots of one or more CORESETs within the active BWP of the serving cell. Optionally, when the network device configures a dl-OrJointTCI-StateList for the terminal and the indicated TCI state is associated with another cell that is different from the serving cell (the indicated TCI state is associated with the PCI of another cell), the QCL assumption of the first CORESET is applied.

[0117] In the second scenario, the terminal receives an initial higher-layer configuration, which includes a list of downlink or combined TCI states for multiple TCI states.

[0118] Before applying the indicated TCI state, where the indicated TCI state is one of the TCI states in the list of TCI states configured by the higher layer as indicated by the network device. The terminal assumes that the L1 CLI-RSSI / CLI-SRS-RSRP measurement resources are quasi-co-located with the SSB identified during random access; or, for the synchronization reconfiguration process, the terminal assumes that the L1 CLI-RSSI / CLI-SRS-RSRP measurement resources are quasi-co-located with the SSB or CSI-RS resources identified during the random access process triggered by the synchronization reconfiguration; or, the terminal assumes that the L1 CLI-RSSI / CLI-SRS-RSRP measurement resources are quasi-co-located with one of the most recently received PDSCH and the most recently monitored CORESET; or, the terminal assumes that the L1 CLI-RSSI / CLI-SRS-RSRP measurement resources are quasi-co-located with one of the most recently received PDSCH, the most recently monitored CORESET, and the most recently received CSI-RS. Alternatively, the protocol specifies that the TCI state with the lowest or highest ID among the TCI states configured by the network device is used.

[0119] For the first and second scenarios above, the QCL assumptions for L1 CLI-RSSI / CLI-SRS-RSRP measurement resources can be specified by agreement, or the network device can indicate the QCL assumptions for L1 CLI-RSSI / CLI-SRS-RSRP measurement resources through indication information.

[0120] For schemes that determine the quasi-co-location of periodic, aperiodic, or semi-persistent layer 1 cross-interference measurement resources with one or more of the resources described above in terms of resources, it is not limited to applying the first and second cases described above.

[0121] In this embodiment of the disclosure, the TCI State of the non-periodic layer 1 (L1) cross-interference measurement resources and the determination method of the periodic, non-periodic, or semi-persistent layer 1 cross-interference measurement resources can be determined, thereby enabling the terminal to determine the beam information related to the measurement and ensuring the accuracy of the terminal measurement.

[0122] In one embodiment of this disclosure, the terminal can determine that a periodic, aperiodic, or semi-persistent Layer 1 cross-interference measurement resource is quasi-co-located with one or more of the following resources in terms of resources, wherein the quasi-co-location type is type D:

[0123] The Channel State Information (CSI) reporting configuration for the periodic, aperiodic, or semi-persistent Layer 1 cross-interference measurement resources includes the Non-Zero Power CSI-RS (NZP CSI-RS) resource for channel measurement, the CSI Intereference Measurement (CSI-IM) resource for interference measurement, and the NZP CSI-RS resource for interference measurement.

[0124] The periodic, aperiodic, or semi-persistent layer 1 cross-interference measurement resources include: resources for measuring RSSI, and / or resources for measuring SRS-RSRP. The resources for measuring RSSI can be AP L1 CLI-RSSI, and the resources for measuring SRS-RSRP can be AP L1 CLI-SRS-RSRP.

[0125] By using the methods described above, channel estimation errors can be reduced, and the reliability and rate of data transmission can be improved.

[0126] Referring to Figure 2, which is a flowchart of an information determination method provided in an embodiment of this disclosure, applied to a network device, as shown in Figure 2, the method includes the following steps:

[0127] Step 201: Send a first instruction to the terminal to indicate the TCI State of the aperiodic layer 1 cross-interference measurement resource; or, determine the TCI State of the aperiodic layer 1 cross-interference measurement resource according to the protocol.

[0128] The non-periodic layer 1 cross-interference measurement resources include: resources for measuring RSSI, and / or resources for measuring SRS-RSRP, wherein the TCI state contains QCL information.

[0129] The meaning of the first indication is the same as described in the foregoing embodiments. If the TCI State of the aperiodic Layer 1 cross-interference measurement resource is determined according to the protocol, the network device can determine the TCI State of the aperiodic Layer 1 cross-interference measurement resource for the first and second scenarios described above, based on the following protocol provisions:

[0130] For the first scenario:

[0131] The protocol specifies that the terminal assumes that the triggered aperiodic L1 crosstalk measurement resource is quasi-co-located with one of the following channels, signals, or measurement resources, with the quasi-co-location type being type D:

[0132] One of the most recently received PDSCH and the most recently monitored CORESET by the terminal; or, one of the most recently received PDSCH, the most recently monitored CORESET, and the most recently received CSI reference signal CSI-RS by the terminal; or,

[0133] The protocol specifies or the first indication is used to instruct: the terminal to apply the indicated TCI State to the aperiodic L1 cross-interference measurement resource; or,

[0134] The protocol specifies or the first indication is used to indicate that: if the target channel or target signal or target measurement resource has the indicated TCI State, the quasi-co-location assumption of the target channel or target signal or target measurement resource is applied to the triggered aperiodic L1 crosstalk measurement resource; otherwise, any of the following information is applied to the triggered aperiodic L1 crosstalk measurement resource:

[0135] Quasi-co-address information of one of the most recently received PDSCH and the most recently monitored CORESET of the terminal;

[0136] Quasi-co-address information of one of the terminal’s most recently received PDSCH, most recently monitored CORESET, and most recently received CSI reference signal CSI-RS;

[0137] Indicated TCI State;

[0138] Quasi-co-address information for the first CORESET;

[0139] Wherein, the target channel or target signal or target measurement resource and the triggered aperiodic L1 cross-interference measurement resource are located on the same symbol; the first CORESET is the CORESET with the smallest control resource set ID in the most recent time slot monitored among one or more CORESETs within the active bandwidth portion (BWP) of the serving cell, associated with the monitoring search space.

[0140] For the second scenario:

[0141] The protocol specifies that the triggered aperiodic L1 crosstalk measurement resource is quasi-co-located with one of the following channels, resources, or signals:

[0142] SSBs identified during random access;

[0143] SSB or CSI-RS resources identified during random access triggered by the synchronization reconfiguration process;

[0144] One of the most recently received PDSCH and the most recently monitored CORESET;

[0145] One of the most recently received PDSCH, the most recently monitored CORESET, and the most recently received CSI-RS;

[0146] or,

[0147] The protocol specifies that the TCI State of the triggered aperiodic L1 cross-interference measurement resource is the TCI State with the lowest or highest ID among the TCI State configured by the network device.

[0148] Based on the above protocol provisions, network devices can determine the TCI State of the aperiodic layer 1 cross-interference measurement resources.

[0149] In this embodiment of the disclosure, the TCI State of the non-periodic layer 1 (L1) cross-interference measurement resources and the determination method of the periodic, non-periodic, or semi-persistent layer 1 cross-interference measurement resources can be determined, thereby enabling the terminal to determine the beam information related to the measurement and ensuring the accuracy of the terminal measurement.
