Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method and apparatus for determining airspace resource information, a storage medium, and a user equipment. Background Art

[0002] In the New Radio (NR) standard versions 15 / 16 (R15 / R16), the path loss reference signal of the Physical Uplink Control Channel (PUCCH) or the Sounding Reference Signal (SRS) resource can be the Transmission Configuration Indicator (TCI) state or the Quasi co-location (QCL) assumption of the Control Resource Set (CORESET) with the minimum identifier (ID) of the downlink active part bandwidth, where the QCL-TypeD periodic Reference Signal (RS). The path loss reference signal of the SRS resource can also be the QCL-TypeD periodic Reference Signal (RS) of the activated TCI state with the minimum ID of the downlink active part bandwidth applicable to the Physical Downlink Shared Channel (PDSCH).

[0028] As described in the background art, in NR version 17 (R17), the QCL-TypeD RS in the TCI state may be the uplink (UL) RS. When the QCL-TypeD RS of the TCI state of the CORESET with the smallest ID is the UL RS, or the QCL-TypeD RS of the active TCI state with the smallest ID applicable to the PDSCH is the UL RS, it cannot be used as the path loss reference signal. There is no specific solution to the above problem currently.

[0029] In the technical solution of the present invention, the spatial domain resource information of the resource is determined by using the QCL-TypeD reference signal of the downlink active part bandwidth as the CORESET of the downlink reference signal, which can avoid the situation where the spatial domain resource information cannot be determined when the QCL-TypeD reference signal of the CORESET is the uplink reference signal, ensure the spatial domain resource information, that is, the availability of the path loss reference signal and / or the spatial domain information, and further ensure the reliability of signal transmission.

[0030] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0031] Figure 1 It is a flowchart of a method for determining spatial domain resource information according to an embodiment of the present invention.

[0032] Figure 1 The method for determining spatial domain resource information shown can be used in a User Equipment (UE), and the method specifically may include the following steps:

[0033] Step S101: Determine the type of the resource, and the type of the resource is selected from PUCCH and / or sounding reference signal;

[0034] Step S102: Determine the spatial domain resource information of the resource at least according to the type of the resource and the CORESET in which the QCL-TypeD reference signal of the downlink active part bandwidth is the downlink reference signal, and the spatial domain resource information is selected from the path loss reference signal and / or the spatial domain information.

[0035] It should be noted that the sequence numbers of the steps in this embodiment do not represent the limitation of the execution sequence of each step.

[0036] In the embodiment of the present invention, the type of the resource is selected from PUCCH and / or sounding reference signal; the spatial domain resource information is selected from the path loss reference signal (pathlossReferenceSignal) and the spatial domain information (SpatialRelationInfo). That is to say, when the UE needs to send a signal, it can determine the path loss reference signal and / or the spatial domain information of the PUCCH, and the path loss reference signal and / or the spatial domain information of the sounding reference signal resource.

[0037] In the embodiment of the present invention, the spatial domain information refers to the directivity of the spatial domain, that is, the spatial domain direction in which the UE sends a signal, or the spatial domain transmission filter; the path loss reference signal can be used for path loss estimation, that is, it can be used to estimate the power when the UE sends a signal.

[0038] It can be understood that each step of the above method is performed when the UE is not provided with the path loss reference signal and spatial domain information of the PUCCH, and the path loss reference signal and spatial domain information of the SRS resource. Among them, the SRS resource cannot be an SRS resource for beam management, or an SRS resource configured by a higher layer for positioning, or an SRS resource configured with an associated Channel State Information reference signal (CSI-RS) and used for non-codebook SRS resources.

[0039] The implementation timing of step S102 can be when the UE needs to send a signal. It can also be other timings when it is necessary to determine the spatial domain resource information, and the embodiments of the present invention do not limit this.

[0040] The QCL-TypeD reference signal of the downlink active part bandwidth may be an uplink signal or a downlink signal, and the uplink signal cannot be used to determine the spatial domain resource information. Therefore, in the specific implementation of step S102, the spatial domain resource information of the resource can be determined according to the CORESET in which the QCL-TypeD reference signal of the downlink active part bandwidth (Bandwidth part, BWP) is a downlink reference signal.

[0041] In the embodiments of the present invention, the spatial domain resource information of the resource is determined by the CORESET in which the QCL-TypeD reference signal of the downlink active part bandwidth is a downlink reference signal, which can avoid the situation where the spatial domain resource information cannot be determined when the QCL-TypeD reference signal of the CORESET is an uplink reference signal, ensure the availability of the spatial domain resource information, that is, the path loss reference signal and / or the spatial domain information, and further ensure the reliability of signal transmission.

[0042] In a non-limiting embodiment of the present invention, the resource is a PUCCH, and the spatial domain resource information is spatial domain information. Please refer to Figure 2 , Figure 1 The step S102 shown may include the following steps:

[0043] Step S201: Determine the spatial domain information of the PUCCH, which is consistent with the spatial domain information of the PDCCH associated with the CORESET with the smallest Identity (ID) in the CORESET in which the QCL-TypeD reference signal of the downlink active part bandwidth of the serving cell is a downlink reference signal.

[0044] In this embodiment, the UE may determine that the spatial domain information of the PUCCH is the same as the spatial domain information of the PDCCH associated with the CORESET with the smallest ID in the CORESET of the DL RS whose QCL-TypeD RS for receiving the downlink active part bandwidth of the Primary cell (Pcell) is the DL RS. In other words, the CORESET with the smallest ID is located in the downlink active part bandwidth of the Pcell, and the QCL-TypeD RS in the CORESET with the smallest ID is the DL RS, and the spatial domain information of the PUCCH is the same as the spatial domain information of the PDCCH for receiving the CORESET associated with the smallest ID (a spatial setting for a PUCCH transmission from the UE is same as a spatial setting for PDCCH receptions by the UE in the CORESET with the lowest ID and QCL-TypeD RS is DL RS on the active DL BWP of the PCell).

[0045] Furthermore, with continued reference to Figure 2 , the method for determining the spatial domain resource information may further include the following steps: Step S202: If the QCL-TypeD reference signals of the CORESET in the downlink active part bandwidth of the primary cell are all uplink reference signals, determine that the spatial domain information of the PUCCH is consistent with the spatial domain information of the active TCI state with the smallest identifier for which the QCL-TypeD reference signal applicable to the PDSCH in the downlink active part bandwidth of the primary cell is a downlink reference signal. That is, the spatial domain information of the PUCCH is consistent with the spatial domain information of the TCI state with the smallest identifier in the active TCI state for which the QCL-TypeD reference signal applicable to the PDSCH in the downlink active part bandwidth of the primary cell is a downlink reference signal.

[0046] In this embodiment, since the QCL-TypeD RSs of the CORESET in the downlink active part bandwidth of the Pcell are all UL RSs, it is impossible to determine the spatial domain information of the PUCCH based on the CORESET in the downlink active part bandwidth of the Pcell. In this case, it is possible to determine the activated TCI state with the smallest Identity (ID) of the QCL-TypeD reference signal applicable to the PDSCH in the downlink active part bandwidth of the Pcell being a DL RS, and then determine that the spatial domain information of the PUCCH is consistent with the spatial domain information of this activated TCI state (a spatial setting for a PUCCH transmission from the UE is same asspatial domain transmission filter used for the reception of the TCI statewith the lowest ID in the activated TCI state(s)with QCL-TypeD RS is DL RSapplicable to PDSCH in the active DL BWP of the PCell).

[0047] In a non-limiting embodiment of the present invention, the resource is a PUCCH, and the spatial domain resource information is a path loss reference signal. Please refer to Figure 3 , Figure 1 shown. Step S102 may include the following steps:

[0048] Step S301: Determine the path loss reference signal of the PUCCH, which is the TCI state of the CORESET with the smallest ID in the CORESET where the QCL-TypeD reference signal in the downlink active part bandwidth of the primary cell is a downlink reference signal, or the QCL-TypeD periodic reference signal in the QCL assumption.

[0049] Different from the foregoing embodiments, the path loss reference signal of the PUCCH is determined in the embodiment of the present invention. The path loss reference signal of the PUCCH may be the TCI state of the CORESET with the smallest ID or the QCL-TypeD RS in the QCL assumption.

[0050] Furthermore, continue to refer to Figure 3, the method for determining the airspace resource information may further include the following steps: Step S302: If the QCL-TypeD reference signals of the CORESET in the downlink active part bandwidth of the primary cell are all uplink reference signals, determine the path loss reference signal of the PUCCH, and it is the QCL-TypeD reference signal of the activated TCI state with the smallest identifier for the QCL-TypeD reference signal applicable to the PDSCH in the downlink active part bandwidth of the primary cell that is a downlink reference signal.

[0051] Different from Figure 2 the embodiment shown, when the QCL-TypeD RSRs of the CORESET in the downlink active part bandwidth of the Pcell are all UL RRs, the path loss reference signal of the PUCCH may be the QCL-TypeD reference signal of the activated TCI state with the smallest identifier.

[0052] In a non-limiting embodiment of the present invention, the resource is the SRS resource, and the airspace resource information is airspace information. Please refer to Figure 4 , Figure 1 the steps shown in S102 may include the following steps:

[0053] Step S401: If the current carrier configures the CORESET, determine the airspace information of the sounding reference signal, which is consistent with the airspace information of the PDCCH associated with the CORESET with the smallest identifier in the CORESET where the QCL-TypeD reference signal of the downlink active part bandwidth of the current carrier is a downlink reference signal.

[0054] Different from Figure 2 the embodiment shown, the airspace information determined in the embodiment of the present invention is the airspace information of the SRS. The airspace information of the SRS is determined according to the CORESET where the QCL-TypeD reference signal of the downlink active part bandwidth of the current carrier is a downlink reference signal, and specifically may be consistent with the airspace information of the PDCCH associated with the CORESET with the smallest identifier (with the same spatial domain transmission filter used for the reception of the CORESET with the lowest controlResourceSetId in the CORESET(s) with QCL-TypeD RS is DLRS in the active DL BWP in the CC (Carrier component, CC)). Herein, the current carrier refers to the carrier where the SRS is located.

[0055] Furthermore, continuing to refer to Figure 4 , the method for determining airspace resource information may further include the following steps:

[0056] Step S402: If all the QCL-TypeD reference signals of the CORESET in the downlink active part bandwidth of the current carrier are uplink reference signals, determine that the airspace information of the sounding reference signal is consistent with the airspace information of the activated TCI state with the smallest identifier for which the QCL-TypeD reference signal applicable to the PDSCH in the downlink active part bandwidth of the current carrier is a downlink reference signal.

[0057] Unlike the Figure 2 embodiment shown, in the embodiment of the present invention, all the QCL-TypeD RSs in the downlink active part bandwidth of the current carrier are UL RSs. At this time, the airspace information of the SRS can be determined according to the activated TCI state with the smallest identifier for which the QCL-TypeD RS applicable to the PDSCH in the downlink active part bandwidth of the current carrier is a DL RS.

[0058] Furthermore, if no CORESET is configured for the current carrier, determine that the airspace information of the sounding reference signal is consistent with the airspace information of the activated TCI state with the smallest identifier for which the QCL-TypeD reference signal applicable to the PDSCH in the downlink active part bandwidth of the current carrier is a downlink reference signal (with the same spatial domain transmission filter used for the reception of the TCI state with the lowest ID in the activated TCI state(s) with QCL-TypeD RS is DL RS applicable to PDSCH in the active DL BWP of the CC if the UE is not configured with any CORESET in the CC).

[0059] In a non-limiting embodiment of the present invention, the resource is an SRS resource, and the airspace resource information is a path loss reference signal. Please refer to Figure 5 , Figure 1 Step S102 shown may include the following steps:

[0060] Step S501: If the current carrier configures a CORESET, determine the path loss reference signal of the sounding reference signal, which is the QCL-TypeD reference signal of the downlink active part bandwidth of the current carrier and is the TCI state of the CORESET with the smallest identifier in the CORESET of the downlink reference signal or the periodic reference signal of QCL-TypeD in the QCL assumption.

[0061] Different from the Figure 4 illustrated embodiment, what is determined in the embodiment of the present invention is the path loss reference signal of the SRS resource. The path loss reference signal of the SRS resource can be the TCI state of the CORESET with the smallest identifier or the periodic reference signal of QCL-TypeD in the QCL assumption.

[0062] Furthermore, with continued reference to Figure 5 , the method for determining the spatial domain resource information may further include the following steps:

[0063] Step S502: If the QCL-TypeD reference signals of the CORESET of the downlink active part bandwidth of the current carrier are all uplink reference signals, determine the path loss reference signal of the sounding reference signal, which is the QCL-TypeD reference signal applicable to the PDSCH of the downlink active part bandwidth of the current carrier and is the QCL-TypeD reference signal of the smallest identified active TCIstate of the downlink reference signal.

[0064] Different from the Figure 4 illustrated embodiment, in the embodiment of the present invention, the QCL-TypeD RSs of the downlink active part bandwidth of the current carrier are all UL RSs. At this time, the path loss reference signal of the SRS can be determined according to the QCL-TypeD RS applicable to the PDSCH of the downlink active part bandwidth of the current carrier, which is the smallest identified active TCI state of the DL RS.

[0065] Even further, if the current carrier does not configure a CORESET, determine the path loss reference signal of the sounding reference signal as the QCL-TypeD reference signal applicable to the PDSCH of the downlink active part bandwidth of the current carrier and is the periodic reference signal of QCL-TypeD in the smallest identified active TCI state of the downlink reference signal.

[0066] In a specific application scenario of the present invention, if the UE is not provided with a path loss reference signal (pathlossReferenceRS), and is also not provided with spatial domain information (SpatialRelationInfo) or TCIstate, the UE determines the path loss reference signal and spatial domain information of the PUCCH in the following manner:

[0067] - Determine that the spatial domain information of the PUCCH is the same as the spatial domain information of the PDCCH associated with the CORESET with the smallest ID in the CORESET of the DLRS for the QCL-TypeD RS that receives the downlink active part bandwidth of the Pcell;

[0068] - Determine that the QCL-TypeD RS for the downlink active part bandwidth of the Pcell is the periodic RS of QCL-TypeD in the TCI state or QCL assumption of the CORESET with the smallest ID in the CORESET of the DL RS, and use it as the path loss reference signal of the PUCCH.

[0069] Furthermore, if the QCL-TypeD RSs of the CORESETs for the downlink active part bandwidth of the Pcell are all UL RSs, then

[0070] - Determine that the spatial domain information of the PUCCH is the same as the spatial domain information of the activated TCI state with the smallest ID of the QCL-TypeD RS for the downlink active part bandwidth of the receiving Pcell applicable to the PDSCH;

[0071] - Determine that the QCL-TypeD RS for the downlink active part bandwidth of the Pcell applicable to the PDSCH is the QCL-TypeD RS of the activated TCI state with the smallest ID of the DL RS, and use it as the path loss reference signal of the PUCCH.

[0072] In another specific application scenario of the present invention, if the UE is not provided with a path loss reference signal and is not provided with spatial domain information either, the UE determines the path loss reference signal and spatial domain information of the SRS resource (wherein, the SRS resource cannot be an SRS resource for beam management, or an SRS resource configured by the higher layer for positioning, or an SRS resource configured with an associated CSI-RS and used for non-codebook) in the following manner:

[0073] If the terminal is configured with a CORESET on the CC, the UE determines the path loss reference signal and spatial domain information of the SRS resource in the following manner:

[0074] - Determine that the spatial domain information of the SRS is the same as the spatial domain information of the PDCCH associated with the CORESET with the smallest ID in the CORESET of the DL RS for the QCL-TypeD RS that receives the downlink active part bandwidth of the CC;

[0075] - Determine that the QCL-TypeD RS for the downlink active part band of the CC is the periodic RS of QCL-TypeD in the TCI state or QCL assumption of the CORESET with the smallest ID of the DL RS, and use it as the path loss reference signal of the SRS.

[0076] Further, if all the QCL-TypeD RSs of the CORESET in the downlink active part bandwidth of the CC are UL RSs, the UE determines the path loss reference signal and spatial domain information of the SRS resource in the following manner:

[0077] - Determine that the spatial domain information of the SRS is the same as the spatial domain information of the activated TCI state with the smallest ID for which the QCL-TypeD RS applicable to the PDSCH in the downlink active part bandwidth of the received CC is a DL RS;

[0078] - Determine the periodic RS of QCL-TypeD in the activated TCI state with the smallest ID for which the QCL-TypeD RS applicable to the PDSCH in the downlink active part bandwidth of the CC is a DL RS as the path loss reference signal of the SRS.

[0079] If no CORESET is configured for the terminal on the CC, the UE determines the path loss reference signal and spatial domain information of the SRS resource in the following manner:

[0080] - Determine that the spatial domain information of the SRS is the same as the spatial domain information of the activated TCI state with the smallest ID for which the QCL-TypeD RS applicable to the PDSCH in the downlink active part bandwidth of the received CC is a DL RS;

[0081] - Determine the periodic RS of QCL-TypeD in the activated TCI state with the smallest ID for which the QCL-TypeD RS applicable to the PDSCH in the downlink active part bandwidth of the CC is a DL RS as the path loss reference signal of the SRS.

[0085] In the embodiment of the present invention, the spatial domain resource information of the resource is determined by using the QCL-TypeD reference signal of the downlink active partial bandwidth as the CORESET of the downlink reference signal, which can avoid the situation where the spatial domain resource information cannot be determined when the QCL-TypeD reference signal is the uplink reference signal, ensure the availability of the spatial domain resource information, that is, the path loss reference signal and / or the spatial domain information, and further ensure the reliability of signal transmission.
