Description

Data sending and receiving method and device Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] During the standardization process for Release 18 (Rel-18), the 3GPP standardization organization conducted research on Layer 1 / Layer 2 Triggered Mobility (LTM). The goal of Rel-18 LTM is to reduce handover interruptions by performing cell handovers based on Layer 1 / Layer 2 signaling (Layer 1 / Layer 2 triggered), thereby enabling faster handovers from the serving cell (source cell) to the target cell.

[0003] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of this application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are explained in the background technology part of this application.

[0004] Summary of the Invention

[0005] Rel-18 studies Layer 1 / Layer 2 Triggered Mobility (LTM). For Rel-18 LTM, the goal is to reduce handover interruption through cell switching based on Layer 1 / Layer 2 signaling (Layer 1 / Layer 2 triggered), so as to switch from the serving cell (source cell) to the target cell faster. The target cell is the cell after switching, which can be a serving cell or a non-serving cell. Handover interruption refers to the time from the terminal device receiving the cell switch command to the first successful completion of uplink or downlink transmission between the terminal device and the target cell. Compared with the traditional cell switching based on Layer 3 signaling, the cell switching based on Layer 1 / Layer 2 signaling can further reduce handover interruption. To achieve cell switching based on layer 1 / layer 2, the terminal device measures multiple candidate cells, for example, measures the layer 1-reference signal receiving power (L1-RSRP) of the system synchronization block (SSB); and reports the measurement results to the source cell, for example, sends a channel state information report (CSI report). The source cell indicates to the terminal device which candidate cell to switch to through a cell switching command (the indicated candidate cell becomes the target cell); and indicates the beam used for uplink and downlink transmission in the target cell after switching, for example, the transmission configuration indication state (TCI state). The source cell, candidate cell, and target cell in Rel-18 LTM all support the Rel-17 unified TCI state (unified TCI). Therefore, the aforementioned indicated TCI state is the unified TCI state.

[0006] In addition, in Rel-18 LTM, the candidate cell configuration (candidate cell configuration), measurement configuration and reporting configuration (CSI report configuration) are provided by the source cell to the terminal device before the cell switching command. The candidate cell configuration includes the Radio Resource Control (RRC) configuration applied by the terminal device after switching to the target cell, that is, the RRC configuration of the target cell. The terminal device can immediately apply the RRC configuration of the target cell after the cell switching, thereby quickly completing the successful uplink or downlink transmission with the target cell; the measurement configuration mainly includes the configuration of the measurement reference signal (such as SSB); the CSI report configuration configures the information required for reporting. For a specific RRC signaling structure, for example, the CSI report configuration is included in the serving cell configuration, and the measurement configuration is located outside the serving cell configuration and the candidate cell configuration.

[0007] The inventors discovered that because the terminal device is configured with measurement configuration information and CSI reporting configuration information independently, a configuration conflict may occur: according to the CSI reporting configuration, the terminal device needs to include the measurement of the SpCell's SSB in the CSI report. However, the measurement configuration does not configure the SpCell's SSB for the terminal device, so the terminal device cannot measure the SpCell's SSB. This configuration conflict can cause undefined device behavior when the terminal device sends CSI reports, resulting in CSI report transmission failures.

[0008] To address at least one of the above problems, embodiments of the present application provide a method and apparatus for sending and receiving data.

[0009] According to one aspect of an embodiment of the present application, a data sending method is provided, which is applied to a terminal device, and the method includes:

[0019] A second sending unit, which sends first configuration information and second configuration information to the terminal device, wherein the first configuration information includes first reference signal location information of one or more candidate cells;

[0020] A second receiving unit receives a channel state information report sent by the terminal device according to the first configuration information and / or the second configuration information; wherein, when the terminal device is configured to include measurements of special cells in the channel state information report, the channel state information report includes or does not include measurements of the special cells.

[0021] According to another aspect of an embodiment of the present application, a communication system is provided, including:

[0024] One of the beneficial effects of the embodiments of the present application is that: a terminal device receives first configuration information and second configuration information, wherein the first configuration information includes first reference signal location information of one or more candidate cells; and sends a channel state information report based on the first configuration information and / or the second configuration information; wherein, when the channel state information report is configured to include measurements of special cells, the channel state information report may or may not include measurements of the special cells. Thus, uncertain device behavior caused by configuration conflicts can be avoided, and inconsistent understanding of CSI report content between the terminal device and the network device can be avoided, thereby avoiding CSI report transmission failures.

[0054] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present application, which schematically illustrates a situation taking a terminal device and a network device as an example. As shown in Figure 1 , a communication system 100 may include a first network device 101, a second network device 102, and a terminal device 103. For simplicity, Figure 1 only illustrates two network devices and one terminal device as an example, but the embodiment of the present application is not limited to this.

[0055] For example, the first network device 101 is the serving cell (source cell) of the terminal device 103 , and the second network device 102 is the cell after switching (target cell) of the terminal device 103 .

[0056] The inventors discovered that: the terminal device is configured with measurement configuration information and CSI report configuration information; the two are configured independently, so the following configuration conflict may occur: according to the CSI report configuration, the terminal device needs to include the measurement of the SSB of the SpCell in the CSI report, however, the measurement configuration does not configure the SSB of the SpCell for the terminal device, so the terminal device cannot measure the SSB of the SpCell. This configuration conflict will cause the terminal device to produce uncertain device behavior when sending the CSI report, resulting in the failure of the CSI report transmission. This configuration conflict is easy to occur because the measurement configuration is configured outside the serving cell configuration (ServingCellConfig) and the candidate cell configuration (candidate cell configuration), while the CSI report configuration information is configured within the serving cell configuration, and the two are independently configured.

[0057] To address at least one of the above problems, embodiments of the present application provide a method and apparatus for sending and receiving data.

[0058] Embodiments of the first aspect

[0059] An embodiment of the present application provides a data sending method, which is applied on a terminal device side.

[0060] FIG2 is a schematic diagram of a data transmission method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0061] 201. A terminal device receives first configuration information and second configuration information, wherein the first configuration information includes first reference signal location information of one or more candidate cells.

[0062] 202. The terminal device sends a CSI report according to the first configuration information and / or the second configuration information; wherein, when the CSI report is configured to include measurements of special cells (SpCells), the CSI report includes or does not include measurements of the special cells (SpCells).

[0063] Thus, the terminal device receives first configuration information and second configuration information, wherein the first configuration information includes first reference signal position information of one or more candidate cells; and sends a channel state information report according to the first configuration information and / or the second configuration information; wherein, in the case where the channel state information report is configured to include measurements of special cells, the channel state information report includes or does not include measurements of the special cells, and when a configuration conflict occurs such as "the terminal device is configured to include measurements of the SSB of the SpCell in the CSI report, but the measurement configuration does not configure the SSB of the SpCell for the terminal device", the terminal device determines the SSB of the SpCell based on the existing configuration when the SpCell is the serving cell, and includes measurements of the SSB of the SpCell and an indication of the SpCell in the CSI report. Thus, uncertain device behavior caused by configuration conflicts can be avoided, and inconsistent understanding of the CSI report content by the terminal device and the network device can be avoided, thereby avoiding failure in CSI report transmission.

[0064] It is worth noting that FIG2 above is merely a schematic illustration of an embodiment of the present application, using a terminal device as an example, but the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, other operations may be added or some operations may be reduced, and the objects of the aforementioned operations may be adjusted. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG2 above.

[0065] In some embodiments, terms such as "transmission configuration indication state (TCI state)" and "beam" can be used interchangeably; "cell" can be equivalently replaced by "carrier" or "component carrier"; "TCI state pool" can be equivalently replaced by "TCI state set" or "TCI state list"; the above is only an exemplary description, and the embodiments of the present application are not limited to this.

[0066] In some embodiments, the serving cell is at least one of the following: a special cell (SpCell), an Scell, an activated cell, and a deactivated cell. Rel-18 LTM supports handover from one cell to a serving cell, an intra-frequency cell, and an inter-frequency cell. For example, a cell to which a terminal device may handover is called a candidate cell, and the cell to which the terminal device actually handsover is called a target cell. A candidate cell can be a serving cell or a non-serving cell.

[0067] For example, for the specific definition of a special cell (Special Cell, SpCell), please refer to the prior art, and this application does not impose any limitation on this.

[0068] In some embodiments, before receiving a cell switch command, the terminal device is configured with one or more candidate cells and provided with configuration information related to the candidate cells; the cell switch command then instructs the terminal device to switch to one or more of the candidate cells (i.e., target cells).

[0069] In some embodiments, the cell to which the terminal device belongs before cell switching is called a "serving cell" or a "source cell," and the cell to which the terminal device belongs after cell switching is called a target cell; for example, the "serving cell" sends a cell switch command to the terminal device, for example, the cell switch command is carried by a media access control layer control element (MAC CE). Thus, the cell switch is indicated by layer 1 or layer 2 signaling, so that the terminal device can quickly switch cells. For example, the MAC CE format corresponding to the cell switch command can refer to the existing technology, and this application does not limit this.

[0070] In some embodiments, the first reference signal is an SSB; the first configuration information is measurement configuration information; and the second configuration information is CSI report configuration information.

[0071] For example, the "serving cell" sends measurement configuration information to the terminal device, and the measurement configuration information includes the candidate cell identifier, first reference signal (for example, SSB) related information, for example, "first reference signal position information", represented by "ssb-PositionsInBurst"; for example, the "serving cell" also sends CSI report configuration information to the terminal device, for example, the terminal device sends a CSI report to the serving cell according to the CSI report configuration information, and the CSI report configuration information includes an indication of whether the CSI report includes measurements of special cells (SpCell).

[0072] Table 1 schematically illustrates the signaling formats of the "first configuration information" and "second configuration information" of this application:

[0073] Table 1

[0074] For example, as shown in Table 1, the first configuration information (measurement configuration information) of the present application includes at least the above-mentioned information element (IE): "LTM-SSB-Info-r18". For example, as shown in Table 1, the second configuration information (CSI report configuration information) of the present application includes at least the above-mentioned IE: "LTM-CSI-ReportConfig". For example, the measurement configuration may not include the above-mentioned "LTM-SSB-Info-r18", and the CSI report configuration may not include "LTM-CSI-ReportConfig". Alternatively, the measurement configuration may include an IE that is different in wording from "LTM-SSB-Info-r18" but has the same function, and the CSI report configuration may also include an IE that is different in wording from "LTM-SSB-Info-r18" but has the same function; this application is not limited to this.

[0075] The terminal device sending the CSI report according to the first configuration information and / or the second configuration information includes:

[0076] For example, the measurement configuration is mainly used to configure the measurement reference signal. The terminal device is configured with measurement configuration information, and the measurement configuration information includes the ssb-PositionsInBurst of the candidate cell. The candidate cell identifier is LTM-CandidateCellId (can also be replaced by ltm-CandidateCellId), which can be a logical cell identifier or a physical cell identifier. The definition of ssb-PositionsInBurst is the same as the existing standard, that is, it indicates the time domain position of the SSB sent in the half frame. This application does not provide detailed descriptions of this; the terminal device measures all or part of the SSB in the ssb-PositionsInBurst, and includes the measured L1-RSRP in the CSI report for transmission.

[0077] In some embodiments, the terminal device may be "configured to include measurements of special cells (SpCells) in the CSI report" according to the received second configuration information and / or fifth configuration information.

[0078] For example, the terminal device is configured by the second configuration information to include measurements of a special cell (SpCell) in the CSI report, including:

[0079] For example, the terminal device is configured with CSI report configuration information through LTM-CSI-ReportConfig, and sends a CSI report according to the CSI report configuration information. For example, the terminal device measures the SSBs of M candidate cells, and then includes the measurements of N (N≤M) candidate cells in the CSI report, that is, selects N from the M candidate cells for reporting. The terminal device can be configured to always include measurements of SpCell in the CSI report, for example, by enabling this function through the IE in Table 1: "SpCellInclusion". If this function is not enabled (disenabled), the selected N cells may include SpCell or not; if this function is enabled (enabled), the selected N cells must include SpCell; the SpCell refers to the SpCell to which the terminal device belonged before the cell switching.

[0080] For example, the terminal device is configured by the fifth configuration information to include measurements of special cells (SpCells) in the CSI report, including:

[0081] In some embodiments, the method further includes: receiving fifth configuration information, wherein the fifth configuration information configures the CSI report to include measurements of special cells (SpCells).

[0082] In some implementations, the fifth configuration information is included in the second configuration information.

[0083] For example, the fifth configuration information configures the CSI report to include the measurement of the special cell (SpCell) in a CSI report per CSI report.

[0084] For example, as shown in Table 1, the fifth configuration information is "SpCellInclusion." "SpCellInclusion" is configured per CSI report. Different CSI reports can have different configurations, i.e., some CSI reports can be configured to include SpCell measurements, while others can be configured not to. This provides greater flexibility in CSI report configuration.

[0085] In some embodiments, the fifth configuration information is configured on a per-UE basis to include measurements of the special cell (SpCell) in the CSI report.

[0086] For another example, taking the fifth configuration information as "SpCellInclusion", "SpCellInclusion" can be configured per terminal device, for example, in addition to "LTM-CSI-ReportConfig" in Table 1. In this case, all CSI reports of the terminal device have the same configuration, that is, all CSI reports of the terminal device include SpCell measurements, or all CSI reports of the terminal device do not include SpCell measurements. As a result, each CSI report is treated equally, making it easier to uniformly process different CSI reports, and saving signaling overhead.

[0087] Thus, the terminal device can be configured to include measurements of special cells (SpCells) in the CSI report according to the second configuration information and / or the fifth configuration information, and send the CSI report according to the configuration of the second configuration information and / or the fifth configuration information.

[0088] After determining the relevant configurations of the "first configuration information", "second configuration information", "fifth configuration information", etc., the following example illustrates "the CSI report includes measurements of the special cell (SpCell):

[0089] In some embodiments, the first configuration information includes first reference signal position information of the special cell (SpCell), and the CSI report includes measurements of the special cell (SpCell); in some embodiments, the first reference signal position information is indicated by the following field: ssb-PositionsInBurst.

[0090] For example, the terminal device is configured to include the measurement of SpCell in the CSI report, for example, by enabling "SpCellInclusion" in Table 1, the N cells selected by the terminal device from the M candidate cells must include SpCell, and "the selected N cells must include SpCell" means that the terminal device must have measured the SSB of SpCell. Since the SSB of SpCell comes from the ssb-PositionsInBurst of SpCell, the measurement configuration information is required to include the ssb-PositionsInBurst of SpCell. If the terminal device is configured to include the measurement of SpCell in the CSI report, the measurement configuration information must include the ssb-PositionsInBurst of SpCell. In other words, when taking SpCell as a candidate cell and configuring the ssb-PositionsInBurst of the candidate cell in the measurement configuration, the ssb-PositionsInBurst of SpCell is also configured.

[0091] In this way, configuration conflicts can be avoided, and inconsistent understanding of the CSI report content between the terminal device and the network device can be avoided, thereby avoiding failure in CSI report transmission.

[0092] In some implementations, the method further includes: 203, the terminal device receives the first information and / or the third configuration information.

[0093] In some embodiments, when the first configuration information does not include the first reference signal location information of the special cell (SpCell), the first reference signal location information of the special cell (SpCell) is determined based on the first reference signal location information in the first information or the third configuration information, and the CSI report includes measurements of the special cell (SpCell).

[0094] In some implementations, the first information is carried by system information; the third configuration information is carried by an RRC message; the system information includes SIB1, and the RRC message includes "ServingCellConfigCommon".

[0095] In some implementations, the first information and / or the third configuration information are parameters configured for the special cell (SpCell). For example, SIB1 and / or ServingCellConfigCommon are parameters configured for the SpCell.

[0096] FIG3 is an example diagram of a CSI report configuration according to an embodiment of the present application.

[0097] For example, as shown in Figure 3, a CSI report configuration is associated with the ssb-PositionsInBurst of M candidate cells (identified by LTM-CandidateCellId), and the CSI report includes measurements of the SSBs of N (N≤M) of these candidate cells. For example, the terminal device is configured to include measurements of SpCell in the CSI report, but the measurement configuration does not configure the ssb-PositionsInBurst of SpCell. In this case, the terminal device determines the ssb-PositionsInBurst of SpCell based on the existing configuration when SpCell is the serving cell. For example, the ssb-PositionsInBurst in SIB1 or "ServingCellConfigCommon" is used as the ssb-PositionsInBurst of SpCell. For example, when both SIB1 and "ServingCellConfigCommon" are configured with ssb-PositionsInBurst, the terminal device determines the ssb-PositionsInBurst of the SpCell based on the ssb-PositionsInBurst configured in "ServingCellConfigCommon".

[0098] For example, the terminal device measures one or more SSBs in the ssb-PositionsInBurst of the SpCell and M candidate cells, and includes the measurement of the SSBs of N cells in the CSI report, and one of the N cells must be the SpCell.

[0099] In this way, the terminal device can determine the ssb-PositionsInBurst of SpCell, so that even if a configuration conflict occurs, the measurement of SpCell can be included in the CSI report, thereby avoiding inconsistent understanding of the CSI report content by the terminal device and the network device, thereby avoiding failure of CSI report transmission.

[0100] In some implementations, the candidate cell identifier of the special cell (SpCell) is a specific value; in some implementations, the specific value is 0.

[0101] For example, the terminal device is configured to include measurements of SpCell in the CSI report. When the measurement configuration does not configure ssb-PositionsInBurs for SpCell, the terminal device uses ssb-PositionsInBurst in SIB1 or ServingCellConfigCommon as ssb-PositionsInBurst for SpCell, and considers that the candidate cell identifier of SpCell is a specific value, that is, the LTM-CandidateCellId of SpCell is a fixed value.

[0102] For example, the specific value mentioned above is a reserved value, used exclusively by the SpCell in the event of a configuration conflict. For example, if the specific value is 0, the value range of LTM-CandidateCellId is [1, Nmax]. Only in the event of a configuration conflict can LTM-CandidateCellId use the specific value 0. In other cases, the value of LTM-CandidateCellId satisfies 1≤LTM-CandidateCellId≤Nmax.

[0103] In some implementations, sending the CSI report includes: the CSI report includes a candidate cell identifier of the special cell (SpCell).

[0104] FIG4 is an example diagram of a CSI report according to an embodiment of the present application.

[0105] For example, as shown in Figure 4, the terminal device includes L1-RSRP, SSB index (SSB index) and candidate cell identifier (LTM-CandidateCellId) in the CSI report to indicate that: for example, L1-RSRP#1 is an SSB measurement for a candidate cell with a candidate cell identifier of LTM-CandidateCellId#1 and an SSB index of SSB index#1. In this CSI report format, when reporting L1-RSRP for SpCell, a specific value is reported as the candidate cell identifier of SpCell. This is because: according to Table 1, if the measurement configuration does not configure ssb-PositionsInBurst for SpCell (for example, LTM-SSB-Info-r18 is not configured for SpCell), then LTM-CandidateCellId is not configured for SpCell. Both the terminal device and the network device use a specific value to avoid ambiguity.

[0106] As a result, both the terminal device and the network device can determine the candidate cell identifier of the SpCell, thereby unifying the understanding of the CSI report content by the terminal device and the network device, thereby avoiding CSI report transmission failure.

[0107] In some implementations, the terminal device may also determine the SSB in the SpCell by using the “first reference signal set associated with the CSI report”, as illustrated below:

[0108] In some embodiments, the method further includes: receiving fourth configuration information, wherein the fourth configuration information configures a first reference signal set associated with the CSI report.

[0109] In some implementations, the fourth configuration information configures the first reference signal of the special cell (SpCell) in the first reference signal set according to the candidate cell identifier of the special cell (SpCell).

[0110] FIG5 is another example diagram of a CSI report configuration according to an embodiment of the present application.

[0111] For example, as shown in Figure 5, the terminal device is configured with an SSB set (LTM-CSI-SSB-Resourcelist) associated with the CSI report. More specifically, a CSI report configuration is not directly associated with the SSB position information (ssb-PositionsInBurst) of the M candidate cells, but is associated with the LTM-CSI-SSB-Resourcelist. The SSB set represented by the LTM-CSI-SSB-Resourcelist includes some or all of the SSBs in the ssb-PositionsInBurst of the M candidate cells. The candidate cell set (LTM-CandidateCellId-list) is an LTM-CandidateCellId set. The elements in the LTM-CandidateCellId set correspond one-to-one to the elements in the SSB set, and are used to identify the candidate cell to which the SSB belongs.

[0112] For example, the terminal device is configured with a candidate cell set and an SSB set associated with the CSI report, where the candidate cell set includes multiple candidate cell identifiers, each of which corresponds to an SSB index in the SSB set. For example, the candidate cell identifier of an SpCell corresponds to the SSB of the SpCell. The terminal device can determine the SSB of the SpCell based on the candidate cell identifier of the SpCell and perform measurements.

[0113] For example, the first two LTM-CandidateCellIds of the candidate cell set shown in Figure 5 are candidate cell identifiers of SpCell, for example, a specific value of "0", which corresponds to the first two SSB indexes of the SSB set, for example, SSB index#1 and SSBindex#2, wherein SSB index#1 and SSBindex#2 are included in the same "ssb-PositionsInBurst", so the terminal device does not need to measure all SSBs in the "ssb-PositionsInBurst", but only needs to measure SSB index#1 and SSBindex#2, which can further reduce the power consumption of the terminal device.

[0114] Table 2 provides a schematic illustration of the signaling format of LTM-CSI-SSB-Resourcelist and LTM-CandidateCellId-list.

[0115] For example, the terminal device is configured to include measurements of SpCell in the CSI report, but the measurement configuration does not configure the ssb-PositionsInBurst of SpCell. In this case, the candidate cell identifier of SpCell can be used to configure the SSB of SpCell for LTM-CSI-SSB-Resourcelist, for example, one or more LTM-CandidateCellIds with a value of 0 (i.e., the specific value described above) are configured in LTM-CandidateCellId-list, and the SSB indexes associated with these LTM-CandidateCellIds are configured in LTM-CSI-SSB-Resourcelist, and these SSB indexes are the SSB indexes in the ssb-PositionsInBurst of SpCell. Although the measurement configuration does not configure the ssb-PositionsInBurst of SpCell, by using the ssb-PositionsInBurst in SIB1 or ServingCellConfigCommon as the ssb-PositionsInBurst of SpCell and using LTM-CandidateCellId with a value of 0 to identify SpCell, the purpose of configuring the SSB of SpCell in LTM-CSI-SSB-Resoutrcelist can still be achieved.

[0116] Table 2

[0117] In some implementations, the fourth configuration information is included in the second configuration information.

[0118] Table 3 provides another schematic illustration of the signaling format of LTM-CSI-SSB-Resourcelist and LTM-CandidateCellId-list.

[0119] Table 3

[0120] For example, as shown in Table 3, the "SSB set associated with the CSI report (LTM-CSI-SSB-Resourcelist) and the candidate cell identifier set (LTM-CandidateCellId-list)" in Figure 5 (corresponding to the fourth configuration information) are configured in the CSI report configuration (LTM-CSI-ReportConfig) (corresponding to the second configuration information).

[0121] In some embodiments, the first reference signal set includes a first reference signal of the special cell (SpCell), and the channel state information report includes a measurement of the special cell.

[0122] For example, if SpCellInclusion is configured, the LTM-CSI-SSB-Resourcelist must include the SSB index of the SpCell.

[0123] For example, if "SpCellInclusion" in Table 1 is configured as "Enabled," the N cells selected by the terminal device from the M candidate cells must include the SpCell. "The selected N cells must include the SpCell" means that the terminal device must have measured the SSB of the SpCell. Therefore, the first reference signal set must include the first reference signal of the special cell (SpCell). For example, the "LTM-CSI-SSB-Resourcelist" must include the SSB index of the SpCell.

[0124] Therefore, by configuring the SSB set associated with the CSI report, the number of SSBs that the terminal device needs to measure can be reduced. Even if the measurement configuration does not configure the SpCell's ssb-PositionsInBurst, the SpCell's SSB can be configured in the SSB set associated with the CSI report, so that the terminal device can include the measurement of the SpCell in the CSI report, avoiding the CSI report transmission failure caused by configuration conflict.

[0125] In some embodiments, when the first reference signal set does not include the first reference signal of the special cell (SpCell), it is considered that the first reference signal set includes the determined first reference signal position information of the special cell (SpCell), and the CSI report includes measurements of the special cell (SpCell); wherein the first reference signal position information of the special cell (SpCell) is determined based on at least one of the following: the first reference signal position information in the first information, the first reference signal position information in the third configuration information, or the first reference signal position information of the special cell in the first configuration information.

[0126] For example, the terminal device is configured to include measurements of SpCell in the CSI report. In this case, even if the LTM-CSI-SSB-Resourcelist does not include the SSB of SpCell, the terminal device considers that the LTM-CSI-SSB-Resourcelist includes the SSB of SpCell. Furthermore, the terminal device considers that the LTM-CSI-SSB-Resourcelist includes all SSBs in the ssb-PositionsInBurst of SpCell. When the measurement configuration information does not include the ssb-PositionsInBurst of SpCell, the terminal device uses the ssb-PositionsInBurst in SIB1 or ServingCellConfigCommon as the ssb-PositionsInBurst of SpCell; when the measurement configuration information includes the ssb-PositionsInBurst of SpCell, but the LTM-CSI-SSB-Resourcelist does not include the SSB of SpCell, the terminal device uses the ssb-PositionsInBurst of SpCell in the measurement configuration information as the ssb-PositionsInBurst of SpCell.

[0127] Therefore, when the first reference signal set does not include the first reference signal of the special cell (SpCell), the terminal device can also determine the first reference signal of the SpCell, so that even if a configuration conflict occurs, the measurement of the SpCell can be included in the CSI report, thereby avoiding inconsistent understanding of the CSI report content by the terminal device and the network device, thereby avoiding failure of CSI report transmission.

[0128] In some implementations, sending the CSI report includes: the CSI report includes a first reference signal resource indicator (SSB Resource Indicator).

[0129] In some implementations, the first reference signal resource indication of the first reference signal in the first reference signal location information of the special cell (SpCell) belongs to the first interval.

[0130] FIG6 is another example diagram of a CSI report according to an embodiment of the present application.

[0131] For example, as shown in Figure 6, the terminal device includes L1-RSRP and SSB resource indicator (SSBRI) in the CSI report. SSBRI is a global index of the SSB in the LTM-CSI-SSB-Resourcelist. For example, still taking Figure 5 as an example, the SSB set associated with the CSI report (LTM-CSI-SSB-Resourcelist) includes 4 SSBs (corresponding to different SSB indexes). For example, the SSBRIs corresponding to the SSB indexes from left to right are "0, 1, 2, 3" respectively. Thus, one SSBRI can identify a candidate cell and an SSB belonging to the candidate cell. If the LTM-CSI-SSB-Resourcelist does not include the SSB of the SpCell, the SSB of the SpCell does not have an SSBRI. In order to still be able to report the SSB of the SpCell in this case, the SSBRI can be determined for the SSB of the SpCell according to predefined rules, so that the terminal device and the network device can have a consistent understanding.

[0132] For example, when the LTM-CSI-SSB-Resourcelist does not include the SSB of SpCell, the terminal device considers that the LTM-CSI-SSB-Resourcelist includes all SSBs in the ssb-PositionsInBurst of SpCell, and considers that the SSBs in the ssb-PositionsInBurst are cascaded with the current LTM-CSI-SSB-Resourcelist into a larger SSB set, and SSBRI is a global index of the SSB in this cascaded large SSB set.

[0133] In some embodiments, the first interval is determined based on a first number of minimum first reference signal resource indications or a first number of maximum first reference signal resource indications, wherein the first number is equal to the number of first reference signals in the first reference signal location information of the special cell (SpCell).

[0134] FIG7 is an example diagram of the first interval of an embodiment of the present application; FIG8 is another example diagram of the first interval of an embodiment of the present application.

[0135] As shown in Figure 7, the ssb-PositionsInBurst of SpCell is concatenated with the LTM-CSI-SSB-Resourcelist in a "pre-positioned" manner; as shown in Figure 8, the ssb-PositionsInBurst of SpCell is concatenated with the LTM-CSI-SSB-Resourcelist in a "post-positioned" manner. Assuming that the SSBRIs are numbered from left to right in ascending order, since the SSBRI is a global index for the concatenated large SSB set, the SSBRI value of the SSB in the ssb-PositionsInBurst of SpCell will be located in a specific first interval, such as the first interval including several minimum SSBRIs in Figure 7, and the first interval including several maximum SSBRIs in Figure 8.

[0136] For example, assuming that the SSBRIs are numbered from left to right in ascending order, as shown in Figure 7, the first interval is an interval including S (first number) minimum SSBRIs, and as shown in Figure 8, the first interval is an interval including S maximum SSBRIs, where S is equal to the number of SSBs in the ssb-PositionsInBurst of the SpCell, that is, the number of SSBs sent in the half frame indicated by ssb-PositionsInBurst.

[0137] Therefore, when there is a configuration conflict, the measurement of the SSB of the SpCell can be included in the CSI report, so that the terminal device and the network device can unify their understanding of the CSI report content, thereby avoiding CSI report transmission failure.

[0138] The following is an example of "the CSI report does not include measurements of the special cell (SpCell)":

[0139] In some embodiments, when the first configuration information does not include the first reference signal location information of the special cell (SpCell), the CSI report does not include measurement of the special cell (SpCell).

[0140] For example, although the terminal device is configured to include SpCell measurements in the CSI report, if the measurement configuration information does not include SpCell's ssb-PositionsInBurst, the terminal device can ignore the configuration of "including SpCell measurements in the CSI report" and thus does not include SpCell measurements in the CSI report. In other words, it is equivalent to the configuration of "including SpCell measurements in the CSI report" being overwritten. For example, "SpCellInclusion" is configured in Table 1, but Table 1 does not configure "LTM-SSB-Info-r18" for SpCell, that is, "ssb-PositionsInBurst" of SpCell is not configured. At this time, the CSI reporting behavior of the terminal device is the same as the CSI reporting behavior when "SpCellInclusion" is not configured. In this way, inconsistent understanding of the CSI report content by the terminal device and the network device can be avoided, thereby avoiding failure in CSI report transmission.

[0141] In some embodiments, when the first reference signal set does not include the first reference signal of the special cell (SpCell), the CSI report does not include measurements of the special cell (SpCell).

[0142] For example, even if a terminal device is configured to include SpCell measurements in a CSI report, if the LTM-CSI-SSB-Resourcelist does not include the SpCell's SSB, the terminal device may ignore the "include SpCell measurements in the CSI report" configuration and thus exclude SpCell measurements from the CSI report. This prevents inconsistent understanding of the CSI report content between the terminal device and the network device, thereby preventing CSI report transmission failures.

[0143] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0144] As can be seen from the above embodiment, the terminal device receives first configuration information and second configuration information, wherein the first configuration information includes first reference signal location information of one or more candidate cells; and sends a channel state information report based on the first configuration information and / or the second configuration information; wherein, when the channel state information report is configured to include measurements of special cells, the channel state information report may or may not include measurements of the special cells. This can avoid uncertain device behavior caused by configuration conflicts, avoid inconsistent understanding of the CSI report content by the terminal device and the network device, and thus avoid CSI report transmission failure.

[0145] Embodiments of the second aspect

[0146] The embodiment of the present application provides a data receiving method, which is applied to a network device.

[0162] As can be seen from the above embodiment, the terminal device receives first configuration information and second configuration information, wherein the first configuration information includes first reference signal location information of one or more candidate cells; and sends a channel state information report based on the first configuration information and / or the second configuration information; wherein, when the channel state information report is configured to include measurements of special cells, the channel state information report may or may not include measurements of the special cells. This can avoid uncertain device behavior caused by configuration conflicts, avoid inconsistent understanding of the CSI report content by the terminal device and the network device, and thus avoid CSI report transmission failure.

[0168] Thus, the terminal device receives first configuration information and second configuration information, wherein the first configuration information includes first reference signal location information of one or more candidate cells; and sends a channel state information report based on the first configuration information and / or the second configuration information; wherein, when the channel state information report is configured to include measurements of special cells, the channel state information report may or may not include measurements of the special cells.
