Description

Information transmission and reception method and apparatus TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication technology. BACKGROUND

[0002] The 3GPP standardization organization studies layer 1 / layer 2 triggered mobility (LTM) in the standardization process of release 18 (Rel-18). For Rel-18 LTM, the goal is to reduce hand over interruption through layer 1 / layer 2 signaling-based (layer 1 / layer 2 triggered) cell switching, so as to switch faster from a serving cell (source cell) to a target cell. The target cell is the cell after switching, which can be a serving cell or a non-serving cell. Hand over interruption refers to the time from receiving a cell switch command by a terminal device to the first successful completion of uplink or downlink transmission by the terminal device with the target cell. Compared with the traditional layer 3 signaling-based cell switching, the layer 1 / layer 2 signaling-based cell switching can further reduce the hand over interruption.

[0003] Rel-18 LTM includes measurement, reporting, beam indication, cell switching, etc. The terminal device measures the system synchronization block (SSB) of the candidate cell, reports the layer 1-reference signal receiving power (L1-RSRP) obtained by measurement to the serving cell, and the serving cell can activate the transmission configuration indication state (TCI state) of the candidate cell for the terminal device. Then, the serving cell sends a cell switching command, instructs the terminal device to switch to a certain candidate cell (i.e., target cell), and indicates the TCI state used in the target cell in the cell switching command.

[0004] For Rel-18 LTM, the terminal device is provided with measurement resource configuration (resource configuration) and reporting configuration, measures the measurement reference signal (such as synchronization signal and PBCH block (SSB), for example, referred to as synchronization information block (SSB)) of the candidate cell according to the resource configuration, and reports the measurement result (such as L1-RSRP) to the serving cell according to the reporting configuration.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical scheme of the present application and facilitating the understanding of those skilled in the art. The above technical scheme cannot be considered as known to those skilled in the art merely because it is described in the background section of the present application.

[0006] SUMMARY

[0007] Rel-19 will continue to enhance LTM, one of the enhancements includes supporting terminal device to perform channel state information reference signal (CSI-RS) based measurement before cell switching. Compared with Rel-18 LTM which only supports SSB based measurement, CSI-RS based measurement is beneficial for terminal device to report narrower beam or more accurate channel state information before cell switching, so that network device can quickly apply narrower beam or more accurate channel state information after terminal device switches to candidate cell, thus enabling terminal device to immediately perform high-reliability and high-speed uplink and downlink transmission after cell switching.

[0008] By enabling terminal device to report measurement results for candidate cell CSI-RS before receiving cell switching command, network device can quickly apply narrower beam or more accurate channel state information after terminal device switches to candidate cell. However, existing standards do not support activating or deactivating semi-persistent CSI-RS resources for candidate cell. How to activate or deactivate semi-persistent CSI-RS resources for candidate cell in LTM procedure is a problem to be solved.

[0009] To at least one of the above problems, the embodiments of the present application provide an information receiving and transmitting method and device.

[0010] According to an aspect of the embodiments of the present application, an information receiving and transmitting device is provided, applied to a terminal device, comprising:

[0011] a first receiving unit configured to receive first information of activating or deactivating semi-persistent channel state information reference signal (CSI-RS) resources and / or semi-persistent channel state information interference measurement (CSI-IM) resources of a first cell or a second cell, wherein the first cell is a serving cell and the second cell is a candidate cell in a Layer 1 / Layer 2 Triggered Mobility (LTM) procedure;

[0012] a first sending unit configured to perform measurement according to the first information and send a CSI report.

[0013] According to another aspect of the embodiments of the present application, an information receiving and transmitting device is provided, applied to a network device, comprising:

[0014] a second sending unit configured to send first information of semi-persistent channel state information reference signal (CSI-RS) resources and / or semi-persistent channel state information interference measurement (CSI-IM) resources of a first cell or a second cell, the first cell being a serving cell of the terminal device, the second cell being a candidate cell in a layer 1 / layer 2 triggered mobility (LTM) procedure;

[0015] a second receiving unit configured to receive a CSI report sent by the terminal device, the CSI report including measurement results of the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources of the candidate cell.

[0016] One of the beneficial effects of the embodiments of the present application is that the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources of the candidate cell in the LTM procedure are activated or deactivated by the first information, thereby facilitating flexible control of the overhead of measurement reference signals, and the CSI report sent by the terminal device includes measurement results of the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources of the candidate cell, which can be applied to a narrower beam or more accurate channel state information after switching to the candidate cell.

[0055] In the embodiments of the present application, the signaling may, for example, be radio resource control (RRC) signaling; for example, referred to as an RRC message (RRC message), for example, including an MIB, system information, a dedicated RRC message; or referred to as an RRC IE (RRC information element). The signaling may, for example, also be MAC (Medium Access Control) signaling; or referred to as a MAC CE (MAC control element). However, the present application is not limited thereto.

[0056] In the following description, the terms “PDCCH” and “physical downlink control channel” or “downlink control information” can be interchangeable without causing confusion, and the terms “PDSCH” and “physical downlink data channel” or “downlink data” can also be interchangeable.

[0057] The terms “PUCCH” and “physical uplink control channel” or “uplink control information” can be interchangeable, and the terms “PUSCH” and “physical uplink data channel” or “uplink data” can also be interchangeable. In addition, transmitting or receiving a PUCCH can be understood as transmitting or receiving downlink control information carried by the PUCCH; and transmitting or receiving a PUSCH can be understood as transmitting or receiving downlink data carried by the PUSCH.

[0058] The following describes some techniques in the LTM process for the convenience of understanding.

[0059] The terminal device measures according to the SSB or the CSI-RS, and according to the above measurement, downlink synchronization with the candidate cell (including the target cell) can be achieved to a certain extent. The terminal device can be triggered by the physical downlink control channel command (PDCCH order) sent by the serving cell to send the physical random access channel (PRACH) to the candidate cell, so as to realize uplink synchronization with the candidate cell. The serving cell indicates the terminal device to switch to which candidate cell (the indicated candidate cell becomes the target cell) through the cell switching command (for example, carried by the medium access control (MAC) control element (CE)), and indicates the beam used for uplink and downlink transmission on the target cell after switching, for example, the beam refers to the transmission configuration indication state (TCI state), wherein the serving cell, the candidate cell and the target cell in the LTM all support the unified TCI state (unified TCI state), therefore, the aforementioned indicated TCI state is the unified TCI state. The terminal device receives the cell switching command, and the cell switching command indicates the target cell and the TCI state applied on the target cell. The terminal device has completed synchronization with the target cell before receiving the cell switching command, and can perform uplink and downlink transmission with the target cell according to the indicated TCI state after switching to the target cell. The source reference signal included in the TCI state IE can be SSB or TRS.

[0060] The unified TCI state can be a joint TCI state or a separate TCI state. The joint TCI state is both a downlink TCI state and an uplink TCI state; the separate TCI state is a downlink TCI state or an uplink TCI state. The serving cell can activate the TCI state of the candidate cell for the terminal device before the cell switching command, and then indicate one (or a pair) of activated TCI states in the cell switching command; or, the serving cell can also indicate one (or a pair) of unactivated TCI states in the cell switching command, which is equivalent to directly indicating and activating the TCI state in the cell switching command.

[0061] A cell that a terminal device can switch to in the LTM is referred to as a candidate cell, and a cell that the terminal device actually switches to is referred to as a target cell. The candidate cell can be a serving cell or a non-serving cell. The terminal device can be provided with a candidate cell configuration, receive a cell switch command and a TCI state indication, switch to the target cell, and apply the indicated TCI state on the target cell.

[0062] FIG. 2 is a schematic diagram of cell switching of the LTM according to an embodiment of the present application. As shown in FIG. 2, the cell CO, the cell CI, and the cell C2 belong to serving cells. For example, the cell CO, the cell CI, and the cell C2 are a group of cells of carrier aggregation, the cell CO is a primary cell (Pcell), and the cell CI and the cell C2 are secondary cells (Scells). For example, the serving cell is at least one of the following: a special cell (SpCell), a Scell, an activated cell, and a deactivated cell. The cell C3, the cell C4, the cell C5, and the cell C6 belong to non-serving cells. For example, the cell C3, the cell C4, the cell C5, and the cell C6 are a group of cells of carrier aggregation, the cell C3 is a Pcell, and the cell C4, the cell C5, and the cell C6 are Scells. Both the serving cells and the non-serving cells can serve as candidate cells.

[0063] The LTM supports switching from one serving cell to another serving cell, an intra-frequency cell, or an inter-frequency cell. For example, switching from the serving cell CO to the serving cell C2 (i.e., the serving cell C2 changes from a Scell to a Pcell), the cell C3 (an intra-frequency cell), or the cell C6 (an inter-frequency cell).

[0064] The terminal device can switch to one or more target cells. For example, switching from a group of serving cells (the cell CO, the cell CI, and the cell C2) of carrier aggregation to a group of non-serving cells (the cell C3, the cell C4, the cell C5, and the cell C6) of carrier aggregation.

[0065] In the following embodiments, "ID" can be replaced by "index" or "identifier". Possible measurement results include at least one of the following information: Reference Singal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Reference Singal Strength Indicator (RSSI), Signal to Interference plus Noise Ratio (SINR) or other signal quality information. The above measurement results can be layer 1 measurement results, and in the following embodiments, L1-RSRP can be replaced by RSRP, L1-SINR can be replaced by SINR, and the like. For the MAC CE shown in the figure, one row of the MAC CE represents one byte (8 bits); the MAC CE does not necessarily include all the fields shown in the figure, and can only include part of the fields; the "R" field represents a reserved bit, which takes a value of 0.

[0066] The inventors have found that how to activate or deactivate a semi-persistent CSI-RS resource for a candidate cell in an LTM procedure is a problem to be solved. In addition, the signaling format for providing a terminal device with CSI-RS resource configuration and CSI report configuration has not been determined. In view of at least one of the above problems, the following embodiments are described.

[0067] Embodiments of the first aspect

[0068] Embodiments of the present application provide an information transceiving method, which is described from the terminal device side.

[0069] FIG. 3 is a schematic diagram of an information transceiving method according to an embodiment of the present application. As shown in FIG. 3, the method comprises:

[0070] 301, a terminal device receives first information for activating or deactivating a semi-persistent Channel State Information Reference Signal (CSI-RS) resource and / or a semi-persistent Channel State Information Interference Measurement (CSI-IM) resource of a first cell or a second cell, wherein the first cell is a serving cell and the second cell is a candidate cell in a Layer 1 / Layer 2 Triggered Mobility (LTM) procedure;

[0071] 302, the terminal device performs measurement according to the first information and sends a CSI report.

[0072] In some embodiments, the semi-persistent CSI-RS resource includes a CSI-RS resource (first semi-persistent CSI-RS resource) for channel measurement and / or a CSI-RS resource (second semi-persistent CSI-RS resource) for interference measurement, and the semi-persistent CSI-IM resource includes a CSI-IM resource for interference measurement. In the following embodiments, the description of the semi-persistent CSI-IM resource can be applied to the second semi-persistent CSI-RS resource, and the following embodiments take the first semi-persistent CSI-RS resource as an example for description.

[0073] In some embodiments, the first cell is a serving cell of the terminal device, and the second cell is a candidate cell in a Layer 1 / Layer 2 Triggered Mobility (LTM) procedure, wherein the first cell can be one or more, and the second cell can be one or more.

[0074] In some embodiments, the terminal device can receive measurement configuration information (CSI-MeasConfig) sent by the network device, which can be used to determine the CSI-RS resource set (NZP-CSI-RS-ResourceSet) and / or the CSI-IM resource set (CSI-IM-ResourceSet) of the first cell, and / or the CSI-RS resource (NZP-CSI-RS-Resource) and / or the CSI-IM resource (CSI-IM-Resource).

[0075] Regarding the measurement configuration information (CSI-MeasConfig), using ASN.1 can be expressed as:

[0076] The following is only an example of an RRC IE, and it is not required that all RRC IEs are established at the same time. Some RRC IEs can be used, and the names of the above IEs are only for illustration. The embodiments of the present application are not limited in this regard.

[0077] In some embodiments, the terminal device can receive the related configuration information (LTM-Config) of the LTM configured by the high layer signaling of the network device, which includes the configuration list (ltm-CandidateToAddModList) of the second cell and the list (ltm-CSI-ResourceConfigToAddModList) of the resource configuration (LTM resource configuration).

[0078] For example, the resource configuration (LTM-CSI-ResourceConfig) includes a resource configuration ID (ltm-CSI-ResourceConfigld), a configuration of a CSI-RS resource group (ltm-NZP-CSI-RS-ResourceGroup) or a CSI-IM resource group (ltm-CSI-IM-ResourceGroup), and the configurations of the CSI-RS resource group and the CSI-IM resource group do not appear simultaneously; wherein the CSI-RS resource group (ltm-NZP-CSI-RS-ResourceGroup) includes a CSI-RS resource list (ltm-NZP-CSI-RS-ResourceList) and a second cell list (ltm-CandidateIdList), and the CSI-RS resources in the CSI-RS resource list and the second cells in the second cell list are in one-to-one correspondence. For example, the ltm-NZP-CSI-RS-ResourceGroup includes a CSI-RS resource ID (NZP-CSI-RS-ResourceId) list and a second cell ID (LTM-CandidateId) list, and the elements of the two lists have a one-to-one mapping relationship, so the ltm-NZP-CSI-RS-ResourceList can include CSI-RS resources from multiple second cells. The CSI-IM resource group (ltm-CSI-IM-ResourceGroup) includes a CSI-IM resource list (ltm-CSI-IM-ResourceList) and a second cell list (ltm-CandidateIdList), and the CSI-IM resources in the CSI-IM resource list and the second cells in the second cell list are in one-to-one correspondence. For example, the ltm-CSI-IM-ResourceGroup includes a CSI-IM resource ID (CSI-IM-ResourceId) list and a second cell ID (LTM-CandidateId) list, and the elements of the two lists have a one-to-one mapping relationship, so the ltm-CSI-IM-ResourceList can include CSI-IM resources from multiple second cells.

[0079] For example, the configuration of the second cell (LTM-Candidate) includes a second cell identity (ltm-CandidateId), a configuration of a CSI-RS resource set (NZP-CSI-RS-ResourceSet), and / or a configuration of a CSI-IM resource set (CSI-IM-ResourceSet), in addition to a configuration of a CSI-RS resource (NZP-CSI-RS-Resource) and / or a configuration of a CSI-IM resource (CSI-IM-Resource).

[0080] The relevant configuration information (LTM-Config) of the LTM can be represented using ASN.1 as follows:

[0081] The following is only an example of RRC IE, and all RRC IEs do not need to be established at the same time. Some RRC IEs can be used, and the names of the above IEs are only examples. Embodiments of the present application are not limited thereto.

[0082] In some embodiments, the terminal device can further receive reporting configuration information sent by the network device, the reporting configuration information including one or more reporting configurations (LTM-CSI-ReportConfig). The reporting configuration indicates which measurement results of which semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources for which cells are reported by the terminal device. The reporting configuration (LTM-CSI-ReportConfig) is associated with the first resource configuration (LTM-CSI-ResourceConfig) and / or the second resource configuration (LTM-CSI-ResourceConfig). The first resource configuration includes a configuration of a CSI-RS resource for channel measurement, and the second resource configuration includes a configuration of a CSI-IM resource or a CSI-RS resource for interference measurement.

[0083] The reporting configuration (LTM-CSI-ReportConfig) can be represented using ASN.1 as follows:

[0084] The following is only an example of RRC IE, and all RRC IEs do not need to be established at the same time. Some RRC IEs can be used, and the names of the above IEs are only examples. Embodiments of the present application are not limited thereto.

[0085] Among them, one LTM report configuration (LTM-CSI-ReportConfig) can be associated with one LTM resource configuration (ltm-ResourcesForChannelMeasurement) for channel measurement, thereby supporting L1-RSRP or L1-SINR reporting (for example, the channel measurement and interference measurement of L1-SINR are both based on the CSI-RS resource in the same LTM resource configuration), or can be associated with one LTM resource configuration (ltm-ResourcesForChannelMeasurement) for channel measurement and one LTM resource configuration (ltm-csi-IM-ResourcesForInterference) for interference measurement, that is, the interference measurement is based on the CSI-IM resource, thereby supporting L1-SINR reporting, or can be associated with one LTM resource configuration (ltm-ResourcesForChannelMeasurement) for channel measurement and one LTM resource configuration (ltm-nzp-CSI-RS-ResourcesForInterference) for interference measurement, that is, the interference measurement is based on the CSI-RS resource, thereby supporting L1-SINR reporting.

[0086] In some embodiments, the report configuration (LTM-CSI-ReportConfig) can be provided in the measurement configuration information (CSI-MeasConfig), which can be represented as:

[0087] The following is only an example of an RRC IE, not all RRC IEs must be true at the same time, and only part of the RRC IEs can be used, and the names of the above IEs are only for example, and the embodiments of the present application are not limited thereto.

[0088] Fig. 10 is a schematic diagram of reporting configuration, resource configuration and association with second cells according to an embodiment of the application. As shown in Fig. 10, LTM-CSI-ResourceConfig with ID 1 associated with ltm-NZP-CSI-RS-ResourceList is used to configure semi-persistent CSI-RS resources, and LTM-CSI-ResourceConfig with ID 2 associated with ltm-CSI-IM-ResourceList is used to configure semi-persistent CSI-IM resources. For example, LTM-CSI-ResourceConfig is a parent IE of ltm-NZP-CSI-RS-ResourceList (or ltm-CSI-IM-ResourceList), i.e. one LTM-CSI-ResourceConfig is used to configure semi-persistent CSI-RS resources or semi-persistent CSI-IM resources. ltm-NZP-CSI-RS-ResourceList can include semi-persistent CSI-RS resources from multiple second cells, for example, it includes Q subsets of NZP-CSI-RS-ResourceSet (i.e. CSI-RS subsets in the figure) from Q second cells. Similarly, ltm-CSI-IM-ResourceList can include semi-persistent CSI-IM resources from multiple second cells. For example, for ltm-NZP-CSI-RS-ResourceList and ltm-CSI-IM-ResourceList associated with the same LTM-CSI-ResourceConfig, the i-th (i≥1) element of ltm-NZP-CSI-RS-ResourceList and the i-th element of ltm-CSI-IM-ResourceList are associated with the same second cell, i.e. are used for channel measurement and interference measurement of the same second cell, for example, ltm-NZP-CSI-RS-ResourceList and ltm-CSI-IM-ResourceList include the same number of elements, and the ltm-CandidateIdList associated with them is the same. One LTM CSI reporting configuration (LTM-CSI-ReportConfig) can be associated with LTM-CSI-ResourceConfig #1 and LTM-CSI-ResourceConfig #2, so that the terminal device reports L1-SINR according to the reporting configuration. In Fig. 10, LTM-CSI-ResourceConfig #2 can also not exist, so that the terminal device reports L1-RSRP or L1-SINR (for example, the channel measurement and interference measurement in L1-SINR are determined according to semi-persistent CSI-RS resources) according to the reporting configuration.

[0089] The above mainly takes the configuration of semi-persistent CSI-RS (CSI-IM) as an example to explain the RRC IE, and the above RRC IE is also applicable to the configuration of periodic CSI-RS (CSI-IM) and / or aperiodic CSI-RS (CSI-IM). Similarly, the above mainly takes the configuration of semi-persistent CSI reporting as an example to explain the RRC IE, and the above RRC IE is also applicable to the configuration of periodic CSI reporting and / or aperiodic CSI reporting.

[0090] In some embodiments, before receiving the cell switching command, the terminal device can also receive first information sent by the network device, and then measure the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource from the first cell and / or the second cell activated by the first information, obtain the measurement result, and send a CSI report including the measurement result to the serving cell according to the aforementioned report configuration (for example, LTM-CSI-ReportConfig), wherein the CSI report includes the measurement result of the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell and / or the second cell. The network device generates a cell switching command according to the measurement result and sends it to the terminal device. The terminal device receives the cell switching command and switches to the target cell. In addition, the first information can also realize the function of deactivating the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell and / or the second cell.

[0091] In some embodiments, the first information includes a first medium access control layer control unit (first MAC CE), wherein the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell or the second cell. That is, one first MAC CE can be used to activate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell, and also can be used to activate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell. Alternatively, the first information includes a first MAC CE and / or a second MAC CE, wherein the second MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell, and the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell. That is, the first MAC CE is only used to activate or deactivate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell, and the second MAC CE is only used to activate or deactivate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell. That is, independent MAC CEs are used for activation or deactivation of the first cell and the second cell, respectively.

[0092] The following are described respectively.

[0093] (I) The first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell or the second cell.

[0094] In some embodiments, one first MAC CE is associated with one logical channel ID (LCID) or enhanced logical channel ID (eLCID).

[0095] In some embodiments, the first MAC CE includes a first field, when the first field is a first value, the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell, or is used for LTM; when the first field is a second value, the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell, or is not used for LTM.

[0096] Figure 4 is an example diagram of the first MAC CE of the embodiments of the present application, as shown in Figure 4, the first field (“L or R” field) indicates whether the first MAC CE is used for the activation / deactivation of the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell of LTM. For example, if the field is 1, the first MAC CE is used to activate / deactivate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource from the second cell, i.e. is used for LTM; if the field is 0, the first MAC CE is used to activate / deactivate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource from the first cell, i.e. is not used for LTM, and vice versa. If the terminal device is not configured with LTM CSI report (e.g. is not configured with ltm-CSI-ReportConfigToAddModList), the first field (“L or R” field) is considered as a reserved field, i.e. is considered as an R field (field is 0).

[0097] In some embodiments, the first MAC CE further includes a second field, when the first field is a first value, the second field indicates the identity of the second cell; when the first field is a second value, the second field indicates the identity of the first cell.

[0098] For example, as shown in FIG. 4, in the case that the first field is 1, the second field (the "Serving / Candidate Cell ID" field) indicates the identity of the second cell (e.g., taking a value equal to ltm-CandidateId minus 1), and the first MAC CE acts on the second cell (e.g., the first MAC CE activates the semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources of the second cell); in the case that the first field is 0, the second field (the "Serving / Candidate Cell ID" field) indicates the identity of the first cell, and the first MAC CE acts on the first cell (e.g., the first MAC CE activates the semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources of the first cell). For example, as shown in FIG. 5, in the case that the first field (the "L or R" field) is 1, the lowest Y bits of the second field are used to indicate the second cell ID, without loss of generality, the "lowest Y bits" can also be replaced by "highest Y bits", and Y can be equal to 3 or other values, which are not limited by the embodiments of the present application.

[0099] In some embodiments, the first MAC CE further comprises a third field, when the first field is a first value, the third field is a reserved field; when the first field is a second value, the third field indicates a BandWidth Part (BWP) identity.

[0100] For example, as shown in FIG. 4, in the case that the first field (the "L or R" field) is 1, the "BWP ID" field is considered as a reserved field, i.e., considered as two R fields, at this time the MAC CE in the eyes of the terminal device is as shown in FIG. 5. In the case that the first field (the "L or R" field) is 0, the "BWP ID" field indicates the BWP on which the first MAC CE acts. In the LTM, the terminal device can not know the BWP configuration of the second cell before the cell switching, therefore, the first MAC CE does not need to indicate the BWP of the second cell when activating / deactivating the semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources of the second cell. Here, the BWP refers to the downlink BWP.

[0101] In some embodiments, the first MAC CE further comprises a fourth field, when the first field is a first value, the fourth field indicates a CSI-RS resource set of the second cell; when the first field is a second value, the fourth field indicates a CSI-RS resource set of the first cell; and / or, the first MAC CE further comprises a fifth field, when the first field is the first value, the fifth field indicates a CSI-IM resource set of the second cell; when the first field is the second value, the fifth field indicates a CSI-IM resource set of the first cell.

[0102] For example, the CSI-RS resource set and / or the CSI-IM resource set corresponding to the second cell can be determined according to the aforementioned IE LTM-Candidate, and the CSI-RS resource set and / or the CSI-IM resource set corresponding to the first cell can be determined according to the aforementioned IE CSI-MeasConfig. Taking the CSI-RS resource set as an example, the NZP-CSI-RS-ResourceSet of the second cell is associated with the ltm-NZP-CSI-RS-ResourceSetToAddModList (including one or more CSI-RS resource sets belonging to the second cell), and the NZP-CSI-RS-ResourceSet of the first cell is associated with the nzp-CSI-RS-ResourceSetToAddModList (including one or more CSI-RS resource sets belonging to the first cell). The CSI-IM-ResourceSet of the second cell is associated with the ltm-CSI-IM-ResourceSetToAddModList, and the CSI-IM-ResourceSet of the first cell is associated with the csi-IM-ResourceSetToAddModList. The maxNrofNZP-CSI-RS-ResourceSets of the second cell is the same as or different from the maxNrofNZP-CSI-RS-ResourceSets of the first cell.

[0103] For example, as shown in FIG. 4, the fourth field (the "SP CSI-RS resource set ID" field) indicates the ID of a NZP-CSI-RS-ResourceSet, where the NZP-CSI-RS-ResourceSet includes one or more semi-persistent CSI-RS resources. In the case that the first field (the "L or R" field) is 1, this field indicates a NZP-CSI-RS-ResourceSet of a second cell, where the second cell is indicated by the second field (the "Serving / Candidate Cell ID" field); in the case that the first field (the "L or R" field) is 0, this fourth field indicates a NZP-CSI-RS-ResourceSet of a first cell, where the first cell is indicated by the second field (the "Serving / Candidate Cell ID" field). Thus, the first MAC CE can activate a semi-persistent CSI-RS resource in a certain NZP-CSI-RS-ResourceSet of a first cell or a second cell, which is illustrated in FIG. 6, where, according to the aforementioned IE example, each first cell or second cell can be configured with multiple NZP-CSI-RS-ResourceSet. Without loss of generality, the NZP-CSI-RS-ResourceSet of the second cell can be replaced with a LTM-NZP-CSI-RS-ResourceSet, i.e., using independent parameters from the NZP-CSI-RS-ResourceSet of the first cell.

[0104] For example, as shown in FIG. 4, the fifth field (the "SP CSI-IM resource set ID" field) indicates the ID of a CSI-IM-ResourceSet, where the CSI-IM-ResourceSet includes one or more semi-persistent CSI-IM resources. In the case that the first field (the "L or R" field) is 1, this fifth field indicates a CSI-IM-ResourceSet of a second cell; in the case that the first field (the "L or R" field) is 0, this fifth field indicates a CSI-IM-ResourceSet of a first cell. The case of "CSI-IM resource" is similar to the case of "CSI-RS resource" above, and other similarities are not repeated.

[0105] In some embodiments, as shown in FIG. 4, the first MAC CE can also include an “IM” field, which indicates whether the byte including the fifth field (“SP CSI-IM resource set ID” field) appears in the first MAC CE. If the “IM” field is 1, the byte appears; if the “IM” field is 0, the byte does not appear. For example, if the CSI report is a report on L1-RSRP, there is no need to perform interference measurement, so the byte does not need to appear.

[0106] In some embodiments, in Rel-19, LTM can also not support L1-SINR reporting, i.e., there is no need to perform interference measurement, so the first MAC CE also does not need to include the fifth field (“SP CSI-IM resource set ID” field). To this end, for example, the terminal device can determine according to the “IM” field (according to the foregoing method), at this time, the byte including the fifth field (“SP CSI-IM resource set ID” field) can be made not to appear in the first MAC CE by setting the “IM” field to 0 (for example, by the following restriction: when the first field (“L or R” field) is 1, the “IM” field must be 0); for another example, when the “L or R” field is 1, the terminal device always considers that the byte including the fifth field (“SP CSI-IM resource set ID” field) does not appear in the first MAC CE, at this time, the “IM” field is considered as the “R” field, i.e., the terminal device does not determine according to the “IM” field, but determines according to the first field (“L or R” field).

[0107] In some embodiments, as shown in FIG. 4, the first MAC CE can also include a “TCI State ID iTCI state ID, which is used as the quasi co-location reference for the CSI-RS resources in the NZP-CSI-RS-ResourceSet, which is indicated by the fourth field (the "SP CSI-RS resource set ID" field). The "TCI State ID0" field indicates the TCI state for the first CSI-RS resource in the NZP-CSI-RS-ResourceSet, the "TCI State ID1" field indicates the TCI state for the second CSI-RS resource in the NZP-CSI-RS-ResourceSet, and so on. The case of the "CSI-IM resource" is similar to the case of the "CSI-RS resource" above, and other similarities are not repeated. The embodiments of the present application do not limit the quasi co-location assumption for the CSI-IM resource, for example, for the CSI-IM resource for interference measurement and the CSI-RS resource for channel measurement associated with the same report configuration, each CSI-IM resource and each CSI-RS resource are quasi co-located with respect to "typeD", and therefore there is no need to explicitly indicate the TCI state for the CSI-IM resource.

[0108] In some embodiments, the first MAC CE further includes an eighth field (the "A / D" field) indicating activation or deactivation, for example, if the eighth field is 1, it means to activate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell or the second cell, and if the eighth field is 0, it means to deactivate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell or the second cell. The first MAC CE including the eighth field can realize both the function of activation and the function of deactivation. In addition, optionally, if the eighth field (the "A / D" field) is 0, all the bytes of the "TCI State ID i " field do not appear in the first MAC CE.

[0109] Alternatively, the first MAC CE can not include the above-mentioned eighth field, i.e., does not explicitly indicate the activation or deactivation through the eighth field, but indicates the activation or deactivation in an implicit manner. When the first MAC CE indicates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell, the first MAC CE activates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell; when the first MAC CE does not indicate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell, the first MAC CE deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell, or the first MAC CE is not used to activate or deactivate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell.

[0110] For example, for “the first MAC CE indicates the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1”, it includes that the first MAC CE indicates the identity of the second cell #1 and / or indicates the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource, or the first MAC CE acts on the second cell #1 and / or the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource.

[0111] For example, for “the first MAC CE does not indicate the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1”, it includes that the first MAC CE indicates any semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #2, or the first MAC CE indicates the second semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1, or the first MAC CE does not act on (i.e., is not used to activate or deactivate) any semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1.

[0112] For example, if the terminal device receives a first MAC CE indicating the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1, it is implicitly indicated that the first MAC CE activates the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1; if the terminal device then receives a first MAC CE that does not indicate the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1, it is implicitly indicated that the first MAC CE deactivates the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell #1. If the terminal device receives a first MAC CE that does not indicate the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1, and the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1 has not been activated before (i.e., is not currently in the activated state), the first MAC CE does not act on the first semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell #1.

[0113] (ii) The second MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell, and the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell. For example, the second MAC CE can be the existing MAC CE used to activate the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the first cell, which will not be described here again. The first MAC CE can be a newly introduced MAC CE, which will be described below.

[0114] In some embodiments, the first MAC CE has a first LCID or eLCID, and the second MAC CE has a second LCID or eLCID. The MAC CE has a first (or second) LCID or eLCID” means that the LCID or eLCID field of the MAC subheader of the MAC CE has a fifth (or sixth) value. That is, after receiving a MAC CE, it is distinguished whether the MAC CE is the first MAC CE or the second MAC CE according to the value of the LCID or eLCID field of the subheader of the MAC CE.

[0115] As some embodiments, the first MAC CE activates or deactivates the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources in a cell unit, and / or, the first MAC CE activates or deactivates the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources in a resource set unit. That is, the first MAC CE activates or deactivates in a cell and / or resource set granularity.

[0116] In some embodiments, the first MAC CE activates or deactivates the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources in one second cell, or, the first MAC CE activates or deactivates the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources in S second cells, where 1≤S≤Smax, 1<Smax.

[0117] In some embodiments, the first MAC CE activates or deactivates the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources in one resource set, or, the first MAC CE activates or deactivates the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources in U resource sets, where 1≤U≤Umax, 1<Umax.

[0118] In some examples, the first MAC CE activates or deactivates the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources in one second cell. The first MAC CE includes a ninth field indicating one second cell, and the ninth field indicates one second cell. The first MAC CE activates or deactivates the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources in one or two resource sets, for example, one of the two resource sets is a CSI-RS resource set and the other is a CSI-IM resource set. Therefore, the first MAC CE includes one or two tenth fields indicating the resource sets, where one of the tenth fields indicates a CSI-RS resource set or a CSI-IM resource set, or, the first MAC CE includes a fourth bitmap indicating whether the first MAC CE is used to activate or deactivate the semi-persistent CSI-RS resources and / or the semi-persistent CSI-IM resources in one or two resource sets, where each bit of the fourth bitmap corresponds to one resource set respectively. One second cell can have multiple CSI-RS resource sets and / or CSI-IM resource sets, and each bit of the tenth field or the fourth bitmap indicates one of the resource sets including semi-persistent CSI-RS resources or semi-persistent CSI-IM resources. For example, only one bit of the fourth bitmap is 1 or 0, and the resource set corresponding to the bit is the resource set including semi-persistent CSI-RS resources or semi-persistent CSI-IM resources.

[0119] For example, FIG. 7 is a first MAC CE example diagram of the embodiments of the present application. As shown in FIG. 7, the ninth field (the "Candidate Cell ID" field, for example, 3 bits in bit width) indicates which second cell the MAC CE acts on. The first MAC CE includes two tenth fields, i.e., the "SP CSI-RS resource set ID" field and the "SP CSI-IM resource set ID" field. The tenth field can refer to the fourth field or the fifth field in (I), and the definition of other fields can also refer to the related description in (I), which will not be repeated here. The first MAC CE shown in FIG. 7 can be regarded as being activated or deactivated in the granularity of the second cell, or can be regarded as being activated or deactivated in the granularity of the second cell and the resource set. As described in the foregoing (I), if the byte including the "SP CSI-IM resource set ID" field does not exist, the first MAC CE only activates or deactivates the semi-persistent CSI-RS resource in one resource set.

[0120] In some examples, the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource of S second cells, where 1≤S≤Smax, 1<Smax. The first MAC CE includes a first bit map indicating whether the first MAC CE is used to activate or deactivate the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource of one or more second cells, where each bit of the first bit map corresponds to one second cell respectively. The first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource in U resource sets, where 1≤U≤Umax, 1<Umax. The first MAC CE includes a plurality of tenth fields indicating one resource set, or the first MAC CE includes a fourth bit map indicating whether the first MAC CE is used to activate or deactivate the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource in one or more resource sets, where each bit of the fourth bit map corresponds to one resource set respectively.

[0121] For example, FIG. 8 is a first MAC CE example diagram of the embodiments of the present application. As shown in FIG. 8, the difference from the method described above is that the first MAC CE can activate or deactivate the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource of more than one second cell. Assuming that the terminal device is configured with a maximum of 8 candidate cells, the first bit map is C8C7C6C5C4C3C2C1, "C i" field (i = 1, 2, …, 8) indicates whether the first MAC CE is used for (activates or deactivates) the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the ith second cell. If the "C i " field is 1, it means that the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the ith second cell is used (activated or deactivated); if the "C i " field is 0, it means that the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the ith second cell is not used (activated or deactivated), and vice versa.

[0122] For example, for the second cell on which the first MAC CE acts on the "C i " field is 1, for example, if the "A / D" field is 1, it means that the first MAC CE activates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell on which the "C i " field is 1; if the "A / D" field is 0, it means that the first MAC CE deactivates the semi-persistent CSI-RS resource and / or semi-persistent CSI-IM resource of the second cell on which the "C i " field is 1. As shown in FIG. 8, the value of Umax is equal to Umax = 2M + 2, where the M + 1 tenth fields ("SP CSI-RS resource set ID0" field to "SP CSI-RS resource set ID M " field) respectively indicate the resource set including the semi-persistent CSI-RS resource for M + 1 (M + 1 ≤ 8) activated second cells, where the activated second cells are arranged in ascending order of i value, but not limited thereto. In other words, the M + 1 activated second cells respectively correspond to 0, 1, …, M in ascending order of i. The "TCI State ID 0,0 " field to "TCI State ID 0,n0 " field respectively indicate the TCI state used as the quasi co-location reference for n0 + 1 CSI-RS resources included in the CSI-RS resource set 0, where the CSI-RS resource set 0 is indicated by the "SP CSI-RS resource set ID0" field. The "TCI State ID 1,0 " field to "TCI State ID 1,n1The M+l tenth fields (the "SP CSI-IM resource set ID0" field to the "SP CSI-IM resource set ID M The M+l tenth fields (the "SP CSI-IM resource set ID0" field to the "SP CSI-IM resource set ID

[0123] The above examples of the tenth field indicating the resource set in FIG. 7 and FIG. 8, but the embodiments of the present application can also use the fourth bitmap to indicate, and the indication method can refer to the first bitmap, which will not be repeated here.

[0124] As some embodiments, the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource in the unit of resource configuration.

[0125] In some embodiments, the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource associated with one resource configuration. The first MAC CE includes the sixth field indicating the one resource configuration, or the first MAC CE includes the second bitmap indicating whether the first MAC CE is used to activate or deactivate the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource associated with one or more resource configurations, wherein each bit of the second bitmap corresponds to one resource configuration. The first MAC CE can or can not include the field indicating the second cell. Wherein the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource associated with the resource configuration indicated by the sixth field or the resource configuration corresponding to the bit with the third value in the second bitmap corresponds to one or more second cells (for example, the association relationship is determined as shown in FIG. 10).

[0126] For example, FIG. 9 is a first MAC CE example diagram of the embodiments of the present application, the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource in the unit of LTM CSI resource configuration (LTM-CSI-ResourceConfig), the first MAC CE can activate or deactivate one LTM-CSI-ResourceConfig for channel measurement or one LTM-CSI-ResourceConfig for interference measurement. The sixth field (the “LTM CSI-RS / CSI-IM resource configuration ID” field) indicates the LTM-CSI-ResourceConfig for configuring the semi-persistent CSI-RS resource, or indicates the LTM-CSI-ResourceConfig for configuring the semi-persistent CSI-IM resource. As shown in FIG. 10, the first MAC CE activates in the unit of LTM-CSI-ResourceConfig, and can activate or deactivate the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource of multiple second cells. The definitions of other fields are the same as described above, and will not be described here. For example, if the sixth field (the “LTM CSI-RS / CSI-IM resource configuration ID” field) indicates the LTM-CSI-ResourceConfig for configuring the semi-persistent CSI-IM resource, the bytes of the “TCI State ID i ” field do not exist; if the sixth field (the “LTM CSI-RS / CSI-IM resource configuration ID” field) indicates the LTM-CSI-ResourceConfig for configuring the semi-persistent CSI-RS resource, the bytes of the “TCI State ID i ” field exist, for example, the “TCI State ID 0,0 ” field to the “TCI State ID 0,n0 ” field indicate the quasi co-location reference of the CSI-RS resource in the ltm-NZP-CSI-RS-ResourceList for channel measurement.

[0127] In some embodiments, the first MAC CE activates or deactivates R resource configurations associated semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources, where 1≤R≤Rmax, 1<Rmax. For example, when R=2, the two resource configurations can be a CSI-RS resource configuration and a CSI-IM resource configuration respectively, and when R>2, the R resource configurations include R1 CSI-RS resource configurations and R2 CSI-IM resource configurations, where R1 and R2 are integers greater than or equal to 0 and less than R. For example, the first MAC CE includes an eleventh field and a twelfth field indicating two resource configurations, or the first MAC CE includes a second bitmap indicating whether the first MAC CE is used to activate or deactivate semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources associated with one or more resource configurations, where each bit of the second bitmap corresponds to a resource configuration. The first MAC CE can or can not include a field indicating the second cell. The semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources associated with the resource configuration corresponding to the two resource configurations indicated by the eleventh field and the twelfth field or the bit of the second bitmap with the third value correspond to one or more second cells (the association relationship is determined as shown in FIG. 10, for example).

[0128] For example, FIG. 11 is an example diagram of the first MAC CE according to an embodiment of the present application, which can activate or deactivate one LTM-CSI-ResourceConfig for channel measurement and one LTM-CSI-ResourceConfig for interference measurement. The eleventh field (the “LTM CSI-RS resource configuration ID” field) indicates an LTM-CSI-ResourceConfig for configuring semi-persistent CSI-RS resources, and the twelfth field (the “LTM CSI-IM resource configuration ID” field) indicates an LTM-CSI-ResourceConfig for configuring semi-persistent CSI-IM resources. The definitions of other fields are the same as or can be obtained according to the foregoing, which will not be described here.

[0129] For example, FIG. 12 is an example diagram of the first MAC CE according to an embodiment of the present application, as shown in FIG. 12, the first MAC CE can activate or deactivate one or more LTM-CSI-ResourceConfig, i.e., activate or deactivate the semi-persistent CSI-RS resources or semi-persistent CSI-IM resources associated therewith. It is assumed that the terminal device is configured with a maximum of 112 LTM-CSI-ResourceConfig, C 112 C 111…C1 is a second bitmap, wherein, "C i " field (i = 1, 2, …, 112) indicates whether to act on (activate or deactivate) the i-th LTM-CSI-ResourceConfig's semi-persistent CSI-RS resource or semi-persistent CSI-IM resource. For all LTM-CSI-ResourceConfig associated with semi-persistent CSI-RS resource activated or deactivated by this first MAC CE, arrange them in ascending order of i. "TCI State ID0" field indicates the quasi co-location reference for the first CSI-RS resource configured by the first LTM-CSI-ResourceConfig (e.g. the first CSI-RS resource in ltm-NZP-CSI-RS-ResourceList in FIG. 10), "TCI State ID1" field indicates the quasi co-location reference for the second CSI-RS resource configured by the first LTM-CSI-ResourceConfig (e.g. the second CSI-RS resource in ltm-NZP-CSI-RS-ResourceList in FIG. 10), and so on until "TCI State ID N " field indicates the quasi co-location reference for the last CSI-RS resource configured by the last LTM-CSI-ResourceConfig.

[0130] In the foregoing embodiments, the first MAC CE can also not consider the second cell, but activate or deactivate semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources separately in resource set granularity. For example, as shown in FIG. 11, the LTM CSI-RS resource configuration ID of the first MAC CE can be replaced by the NZP-CSI-RS-ResourceSet ID of the LTM; similarly, as shown in FIG. 11, the LTM CSI-IM resource configuration ID can be replaced by the CSI-IM-ResourceSet ID of the LTM. Here, no longer one by one example.

[0131] As some embodiments, the first MAC CE activates or deactivates semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources in reporting configuration units.

[0132] In some embodiments, the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource associated with one reporting configuration. The first MAC CE includes a seventh field indicating the one reporting configuration, or the first MAC CE includes a third bitmap indicating whether the first MAC CE is used to activate or deactivate the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource associated with one or more reporting configurations, wherein each bit of the third bitmap corresponds to one of the reporting configurations respectively. The semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource associated with the reporting configuration indicated by the seventh field or the reporting configuration corresponding to the bit with the fourth value in the third bitmap is corresponding to one or more second cells (for example, the association is determined as shown in FIG. 10).

[0133] For example, FIG. 13 is an example diagram of the first MAC CE according to an embodiment of the present application. As shown in FIG. 13, the first MAC CE activates or deactivates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource in units of LTM CSI reporting configuration (LTM-CSI-ReportConfig). The first MAC CE can activate or deactivate one LTM-CSI-ReportConfig (and thus activate or deactivate the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource associated with the LTM-CSI-ReportConfig). The first MAC CE includes a seventh field LTM CSI report configuration ID indicating the one reporting configuration LTM-CSI-ReportConfig. As shown in FIG. 10, one LTM-CSI-ReportConfig can be associated with one LTM-CSI-ResourceConfig for configuring the semi-persistent CSI-RS resource, or can be associated with one LTM-CSI-ResourceConfig for configuring the semi-persistent CSI-RS resource and one LTM-CSI-ResourceConfig for configuring the semi-persistent CSI-IM resource, thereby determining the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource associated with the LTM-CSI-ReportConfig. For all semi-persistent CSI-RS resources (for example, the CSI-RS resources included in ltm-NZP-CSI-RS-ResourceList in FIG. 10) activated by the first MAC CE, the “TCI State ID0” field is indicated by the first CSI-RS resource as the quasi co-location reference, the “TCI State ID1” field is indicated by the second CSI-RS resource as the quasi co-location reference, and so on.

[0134] In some embodiments, the first MAC CE activates or deactivates the semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources associated with P reporting configurations, where 1≤P≤Pmax, 1<Pmax. The first MAC CE includes a plurality of seventh fields each indicating one of the reporting configurations, or the first MAC CE includes a third bitmap indicating whether the first MAC CE is used to activate or deactivate the semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources associated with one or more reporting configurations, where each bit of the third bitmap corresponds to one of the reporting configurations. The semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources associated with the reporting configuration indicated by the seventh field or the reporting configuration corresponding to the bit of the third bitmap having the fourth value are associated with one or more second cells (for example, the association is determined as shown in FIG. 10).

[0135] For example, FIG. 14 is an example diagram of a first MAC CE according to an embodiment of the present application. As shown in FIG. 14, the first MAC CE can activate or deactivate one or more LTM-CSI-ReportConfig, i.e., activate or deactivate the semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources associated therewith. Assume that the terminal device is configured with a maximum of 48 LTM-CSI-ReportConfig, C 48 C 47 …C1 corresponds to the third bitmap, “C i ” field (i=1, 2, …, 48) indicates whether to act on (activate or deactivate) the semi-persistent CSI-RS resources and / or semi-persistent CSI-IM resources of the i-th LTM-CSI-ResourceConfig. For all LTM-CSI-ReportConfig activated by the first MAC CE, they are arranged in order of i from small to large. The TCI State ID0 field indicates the quasi co-location reference for the first CSI-RS resource associated with the first LTM-CSI-ReportConfig (for example, the first CSI-RS resource in ltm-NZP-CSI-RS-ResourceList in FIG. 10), the TCI State ID1 field indicates the quasi co-location reference for the second CSI-RS resource associated with the first LTM-CSI-ReportConfig (for example, the second CSI-RS resource in ltm-NZP-CSI-RS-ResourceList in FIG. 10), and so on, until the “TCI State ID N ” field indicates the quasi co-location reference for the last CSI-RS resource associated with the last LTM-CSI-ReportConfig.

[0136] For the foregoing embodiments, for example, Figs. 7-9, 11-14, the first MAC CE further comprises an eighth field (an “A / D” field) indicating activation or deactivation, or, when the first MAC CE indicates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource of the second cell, the first MAC CE activates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource of the second cell; when the first MAC CE does not indicate the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource of the second cell, the first MAC CE deactivates the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource of the second cell, or the first MAC CE is not used to activate or deactivate the semi-persistent CSI-RS resource and / or the semi-persistent CSI-IM resource of the second cell. For the foregoing embodiments of activation or deactivation, refer to (1) above, which will not be repeated here.
