Description

Technical Field

[0001] This application belongs to the technical field of wireless communication, and specifically relates to a transmission method, apparatus, communication device, and terminal.

Background Art

[0002] In related technologies, in some cases, the space information of a certain uplink channel or uplink signal needs to be determined based on the space information of a reference resource. Primarily includes: receiving space information used for downlink channels and downlink signals when the reception of space information for downlink channels and downlink signals is not configured, activated, or instructed, and in other cases where it cannot be determined, where downlink channels include Physical downlink shared channels (PDSCH) or PDSCH scheduled by Component Carrier (CC), and downlink signals include Aperiodic Channel State Information Reference Signals (AP-CSI-RS), and transmitting space information used for uplink channels and uplink signals when the transmission of space information for uplink channels and uplink signals is not configured, activated, or instructed, and in other cases where it cannot be determined, where uplink channels include Physical Uplink Shared Channels (PUSCH), Physical Uplink Control Channels (PUCCH), and uplink signals include Sounding Reference Signals (SRS), etc. In the above case, the downlink channel, the space information for receiving the downlink signal, the uplink channel, and the space information for transmitting the uplink signal generally correspond to the space information of the reference resource, where the reference resource may be a control resource set (CORESET), a physical downlink control channel (PDCCH) that schedules this downlink channel / signal and uplink channel / signal, or other channels / signals.

[0003] For example, if the upper-layer parameter tci-PresentInDCI, located in a CORESET for a single terminal (also called User Equipment, UE), is set to "enabled," the UE assumes that the Downlink Control Information (DCI) format 1_1 or DCI Format 1_2 in the PDCCH transmitted over this CORESET includes a Transmission Configuration Indication (TCI) field, which is used to indicate information including the spatially received beam, such as the TCI state. Only if the UE detects the DCI can it correctly decode the TCI state and determine the received beam used to receive the PDSCH scheduled by this PDCCH. If the UE needs a certain amount of time to detect the DCI and switch beams based on the TCI indication, and the DCI format 1_1 indicates a time offset for scheduling the PDSCH, then the UE may receive the PDSCH of the serving cell according to the received beam indicated by the TCI field in this DCI, i.e., the Demodulation Reference Signal (DMRS) port and the TCI field of the single-slot or multi-slot PDSCH indicate a TCI state reference signal (RS) which can be considered quasi-co-located (QCL).If the upper-layer parameter tci-PresentInDCI, which is placed in one CORESET, is set to "enabled", or if the upper-layer parameter tci-PresentInDCI is not placed, then all TCI code points activated by the Control Element (CE) of the Medium Access Control (MAC) layer are mapped as a single TCI state, and the above time offset is less than timeDurationForQCL, then the UE has not completed DCI detection or the receive beam switching operation, and the UE may cache the received signals on these symbols using the default receive beam, thereby facilitating the demodulation of the scheduled PDSCH after successful DCI detection. The UE may receive the PDSCH using the default receive beam, i.e., the UE may consider the DMRS port of the serving cell's PDSCH and the RS in the QCL parameter for PDCCH QCL indication in the CORESET to be the QCL, where the CORESET is the CORESET having the smallest CORESET ID associated with the monitoring search space (SS) in one or more CORESETs on the activated bandwidth part (BWP) of the serving cell monitored by the UE in the nearest slot.

[0004] However, in some scenarios, a reference resource for an uplink or downlink channel or uplink / downlink signal may correspond to multiple spatial information, and in such cases, the communication equipment cannot determine the spatial information for the uplink or downlink channel or uplink / downlink signal. For example, in a multi-transmission and reception point (TRP) scenario, as an implementation to enhance the reliability of the control channel, a PDCCH is transmitted across multiple TRPs to reduce the probability of beamlink failure. In such cases, the PDCCH may correspond to multiple TCI states or QCLs, and if the UE assumes that RS in the QCL parameter for PDCCH QCL indication in the DMRS port of the serving cell's PDSCH and CORESET is QCL, then the UE cannot determine the spatial information for receiving the PDSCH because the PDCCH corresponds to multiple different TCI states or QCLs.

[0021] In the following, with reference to the drawings, the transmission method according to the embodiments of the present application will be described in detail by way of specific embodiments and their application scenarios.

[0022] FIG. 2 shows a flowchart of the transmission method in the embodiments of the present application. This method 200 may be executed by a communication device. In other words, the method may be executed by software or hardware installed in the communication device. As shown in FIG. 2, this method may include the following steps.

[0023] In S210, when the first space information of the target object is determined based on the second space information corresponding to the reference resource, the communication device determines that the first space information of the target object corresponds to the target space information, where the reference resource corresponds to a plurality of second space information, and the target space information is one or more of the plurality of second space information.

[0024] In the embodiments of this application, the fact that the first spatial information of the target is determined based on the second spatial information corresponding to the reference resource means that the first spatial information of the target cannot adopt the spatial information indicated in the downlink control information, or that the first spatial information of the target is not indicated in the downlink control information. For example, if the upper-layer parameter tci-PresentInDCI placed on a single CORESET is set to "enabled", and the DCI in the PDCCH transmitted on this CORESET adopts DCI format 1_1 or DCI format 1_2, and this DCI includes a TCI field, and the symbol interval between the last symbol of the PDCCH where this DCI is located and the first symbol of the single-slot or multi-slot PDSCH it schedules is smaller than a first preset threshold (timeDurationForQCL), then the first spatial information of the target object (in this case the PDSCH) is determined based on the second spatial information of the reference resource, where the reference resource is the CORESET with the smallest ID among the CORESETs associated with the monitored search space of the nearest time unit (e.g., a slot, sub-slot, or multiple OFDM symbols in one or more slots (e.g., SPAN)).

[0025] In the embodiments of this application, the fact that the reference resource corresponds to a plurality of second spatial information includes having one reference resource corresponding to a target object, and this reference resource corresponding to a plurality of second spatial information, or having a plurality of reference resources corresponding to a target object, i.e., the reference resource includes a plurality of sub-reference resources, each sub-reference resource corresponding to one or more second spatial information.

[0026] For example, taking the reference resource as a PDCCH or search space, in a real application, the PDCCH may be transmitted using one of the following methods (1) or (2).

[0027] (1) A time-frequency resource of a PDCCH or search space corresponds to different second space information according to certain rules based on a certain resource granularity and is transmitted using frequency division multiplexing (FDM) or time division multiplexing (TDM). Here, the resource granularity may be a control-channel element (CCE), a resource element group (REG), a REG bundle, a precoder granularity, a PDCCH candidate, a search space detection opportunity, etc.

[0028] (2) Different second spatial information corresponding to multiple transmissions of a single PDCCH is transmitted using Spatial Division Multiplexing (SDM), FDM, TDM, or a combination thereof.

[0029] Therefore, in one possible implementation, PDCCH corresponding to multiple second space information includes at least one of the following (1) to (4).

[0030] (1) A single PDCCH belongs to a single search space, or multiple transmissions of a PDCCH belong to a single search space, and this search space is associated with a single CORESET, where this CORESET corresponds to at least two second space information units.

[0031] (2) A single PDCCH belongs to a single search space, or multiple transmissions of a PDCCH belong to a single search space, and this search space is associated with at least two CORESETs, where each CORESET corresponds to a second space information.

[0032] (3) Multiple transmissions of PDCCH belong to different search spaces, and each search space is associated with the same CORESET, where this CORESET corresponds to at least two second space information units.

[0033] (4) Multiple transmissions of PDCCH belong to different search spaces, and each search space is associated with one CORESET, where each CORESET corresponds to one second space information.

[0034] In another possible implementation, the terminal is arranged such that multiple search spaces are used to transmit the same PDCCH, and the multiple search spaces correspond to multiple second space information, which includes at least one of (1) and (2) below.

[0035] (1) The plurality of search spaces are associated with at least two CORESETs, where each CORESET corresponds to one second space information.

[0036] (2) The plurality of search spaces are associated with the same CORESET, where this CORESET corresponds to at least two second space information, and each search space corresponds to one of the second space information of this CORESET.

[0037] The above-mentioned PDCCH, search space, or CORESET may each belong to the same TRP. In a Multiple TRP (MTRP) scenario, the above-mentioned PDCCH, search space, or CORESET may each belong to different TRPs.

[0038] In the embodiments of this application, the target space information may be one or more of a plurality of second space information, and whether it is specifically one or more may be determined based on a pre-set, agreed upon, or actual scheduling. For example, if there are a plurality of space information indicated by the DCI for scheduling downlink channels / downlink signals or uplink channels / uplink signals, the target space information may be a plurality of the plurality of second space information, or if there are a plurality of second space information for locating and / or activating reference resources, the target space information may be a plurality of the plurality of second space information.

[0039] In one possible implementation, the target space information may be one or more second space information pieces with the strongest signal strength among a plurality of second space information pieces. Here, if the communication device is a terminal, the signal strength may be obtained by measuring the received signals corresponding to the plurality of second space information pieces. For example, the signal strength of this space information may be obtained by measuring the quality of the DMRS signal of a PDCCH transmitted using a certain space information or the RS quality transmitted using a certain space information. If this possible implementation is adopted and the target is an uplink channel or uplink signal, the transmission of the target can be guaranteed to ensure the reliability of the uplink channel or uplink signal transmission by adopting the first space information corresponding to the second space information with the strongest signal strength.

[0040] Alternatively, in another possible implementation, the target space information may be one or more pre-specified second space information from among a plurality of second space information, for example, the first space information of a reference resource.

[0041] In another possible implementation, if the reference resource includes multiple sub-reference resources, the target space information may be a second space information corresponding to one or more pre-configured sub-reference resources among the multiple sub-reference resources. For example, if the reference resource includes multiple search spaces for transmitting the same PDCCH, and the multiple search spaces are associated with different CORESETs, and each CORESET corresponds to one of the multiple space information, then the target space information may be the space information corresponding to the CORESET with the smallest CORESET ID among the multiple CORESETs, or the target space information may be a space relationship corresponding to a CORESET associated with a particular search space among the multiple search spaces.

[0042] In the above possible implementation, the number of second space information entries corresponding to the pre-configured sub-reference resource may be pre-configured or agreed upon to be one or more. For example, if the protocol specifies that there is one space information entry corresponding to CORESET#0 (e.g., TCI status or QCI), or if DCI scheduling indicates that the target (e.g., PDSCH or PUSCH) is a multi-TRP transmission, the number of second space information entries corresponding to the pre-configured sub-reference resource may be pre-configured, agreed upon, or activated to be multiple. That is, in this possible implementation, the number of second space information entries corresponding to the pre-configured sub-reference resource may be pre-configured, agreed upon, or activated to be the same as the number of second space information entries included in the target space information.

[0043] Alternatively, in another possible implementation, if the reference resource includes multiple sub-reference resources, the target space information is one or more second space information pieces with the strongest signal strength among multiple second space information pieces corresponding to the multiple sub-reference resources. Here, if the communication device is a terminal, the signal strength may be obtained by measuring based on signals transmitted from multiple TRPs, for example, by measuring the DMRS signal quality of a PDCCH transmitted using a certain space information or the RS quality transmitted using a certain space information to obtain the signal strength of this space information.

[0044] In one possible transmission scheme, the target object may have multiple transmission resources, and the first spatial information used for the transmission of the target object on different transmission resources may correspond to a plurality of second spatial information contained in the target spatial information according to a mapping rule, wherein the plurality of transmission resources include at least one of a plurality of time-division multiplexing transmission resources, a plurality of frequency-division multiplexing transmission resources, a plurality of spatial-division multiplexing transmission resources, and a plurality of code-division multiplexing transmission resources.

[0045] For example, if the target is transmitted at different frequencies, the first spatial information used for the transmission of the target at different frequencies may correspond to a plurality of second spatial information contained in the target spatial information, according to a pre-set mapping rule. For example, if the plurality of second spatial information contained in the target spatial information are spatial information 1 and spatial information 2, and the target is transmitted over frequency-domain orthogonal subcarrier group 1 and subcarrier group 2, according to the mapping rule, it can be determined that the first spatial information used by the target in subcarrier group 1 corresponds to spatial information 1, and the first spatial information used by subcarrier group 2 corresponds to spatial information 2.

[0046] Alternatively, the target object may be transmitted multiple times on orthogonal time resources, and the first spatial information used in each transmission corresponds to one of the multiple second spatial information pieces included in the target spatial information, according to the mapping rule. For example, if the target spatial information includes two second spatial information pieces, spatial information 1 and spatial information 2, according to the alternating mapping rule, the first spatial information of the target object in the first transmission corresponds to spatial information 1, the first spatial information of the second transmission corresponds to spatial information 2, the first spatial information of the third transmission corresponds to spatial information 1, and the first spatial information of the fourth transmission corresponds to spatial information 2, and so on, with the mapping alternating. Alternatively, a mapping rule may be adopted in which n consecutive repetitions correspond to the same second spatial information. For example, if n=2 and the target spatial information includes two second spatial information pieces, spatial information 1 and spatial information 2, then the first spatial information of the first transmission of the target corresponds to spatial information 1, the first spatial information of the second transmission corresponds to spatial information 1, the first spatial information of the third transmission corresponds to spatial information 2, the first spatial information of the fourth transmission corresponds to spatial information 2, and so on, mapping in a cyclical manner.

[0047] Alternatively, when the target object is transmitted over different spatial domain resources (e.g., different layers of MIMO), the first spatial information used for transmitting the target object in different spaces may correspond to multiple second spatial information pieces included in the target spatial information, according to pre-configured mapping rules. For example, if the multiple second spatial information pieces included in the target spatial information are spatial information 1 and spatial information 2, and the target object is transmitted over layers 1 and 2, according to the mapping rules, it can be determined that the first spatial information used by the target object at layer 1 corresponds to spatial information 1, and the first spatial information used at layer 2 corresponds to spatial information 2.

[0048] Alternatively, in another feasible transmission method, the target object has one or more transmission resources, and the target space information is one of the multiple second space information pieces, that is, in this feasible implementation method, even if the target object has multiple transmission resources, the first space information used for transmission in each transmission resource corresponds to the same second space information, that is, the first space information used for transmission in each transmission resource is the same.

[0049] In each of the possible implementations described above, if multiple first identifiers are placed on the terminal transmitting the target object, the first identifier corresponding to the reference resource is the same as the first identifier corresponding to the target object. For example, the first identifier may be a CORESETPoolIndex, which is a Radio Resource Control (RRC) parameter used to identify a TRP. The network may place multiple CORESETs on the terminal, each associated with a different CORESETPoolIndex value, to distinguish the TRP to which each CORESET belongs.

[0050] In one possible implementation, the reference resource may be located in the same time unit as the target object. That is, in this possible implementation, the first spatial information of the target object corresponds to the second spatial information of the reference resource within the same time unit.

[0051] In the above possible implementation methods, a single time unit may be a single slot, or a portion of orthogonal frequency division multiplex (OFDM) symbols within a single slot, or multiple slots, or a portion of OFDM symbols within multiple slots; this embodiment is not specifically limited to these.

[0052] In one possible implementation, the target may include any one of the following: an uplink channel, a downlink channel, an uplink signal, a downlink signal, and CORESET#0.

[0053] In one possible implementation, the reference resource includes one of the following: a CORESET, a search space, a PDCCH for scheduling the target, a Physical Up-link Control Channel (PUCCH), space information to be located and / or activated, and a Synchronization Signal and PBCH block (SSB).

[0054] In one possible implementation, the first spatial information includes one of the following: TCI state, QCL, and Spatial Relation.

[0055] In the embodiments of this application, the first space information corresponding to the target space information may be target space information, for example, the target space information may be a TCI state and the first space information may be this TCI state. Alternatively, the first space information corresponding to the target space information may be space information having a correspondence with the target space information, for example, the target space information may be a TCI state or QCL and the first space information may be a space relationship corresponding to this TCI state or QCL.

[0056] In S212, The first spatial information determined is used to transmit the target object. .

[0057] In embodiments of this application, transmitting the target object includes receiving the target object or transmitting the target object. For example, if the target object is a downlink channel (e.g., PDSCH), the communication device may be a network-side device or a terminal. If it is a network-side device, it transmits the downlink channel by adopting first space information corresponding to the target space information, and if it is a terminal, it receives the downlink channel by adopting first space information corresponding to the target space information.

[0058] The following describes the technical proposal according to the embodiments of this application, using a terminal as an example and applying to different target objects.

[0059] Example 1 In this embodiment, the technical proposal according to the embodiment of this application will be explained using the PDSCH as an example.

[0060] In this embodiment, when the PDCCH where the DCI detected by the UE is located corresponds to multiple TCI states, if the DCI does not indicate a TCI state for the PDSCH, for example, if the detected DCI is DCI format 1_0, or if the detected DCI is DCI format 1_1 or DCI format 1_2 in which tci-PresentInDCI is not placed, or if the detected DCI indicates one TCI state, but the symbol interval between the last OFDM symbol of the PDCCH where this DCI is located and the first OFDM symbol of the single-slot or multi-slot PDSCH scheduled by this PDCCH is smaller than a first threshold (e.g., timeDurationForQCL), then the TCI state or QCL of the PDSCH scheduled by this PDCCH is determined based on the TCI state or QCL corresponding to a reference resource (a given CORESET, i.e., a CORESET associated with the nearest time unit detection search space).

[0061] In a multi-TRP scenario, PDCCH can be enhanced by employing (1) a method in which the time-frequency resources of a single PDCCH are transmitted in an FDM or TDM manner according to certain rules based on a resource granularity, corresponding to different TCI states, and (2) a method in which multiple transmissions of a single PDCCH correspond to different TCI states and are transmitted in an SDM, FDM, TDM, or combination thereof manner.

[0062] Therefore, the PDCCH where the DCI detected by the UE is located can correspond to multiple TCI states, including, but not limited to, the following 1) to 4).

[0063] 1) A single PDCCH detected by the UE belongs to a first search space, or multiple transmissions of a PDCCH belong to a first search space, and this first search space is associated with a CORESET, where this CORESET corresponds to at least two TCI states.

[0064] 2) A single PDCCH detected by the UE belongs to a second search space, or multiple transmissions of a PDCCH belong to a second search space, and this second search space is associated with at least two CORESETs, where each CORESET corresponds to a single TCI state.

[0065] 3) Multiple transmissions of PDCCH detected by the UE belong to different third search spaces (i.e., a single search space group), and each of these third search spaces is associated with the same CORESET, where this CORESET corresponds to at least two TCI states.

[0066] 4) Multiple transmissions of PDCCH detected by the UE belong to different fourth search spaces, and each fourth search space is associated with one CORESET, where each CORESET corresponds to one TCI state.

[0067] In this embodiment, if no TCI state is indicated in the detected DCI, or if one TCI state is indicated in the detected DCI, and if the symbol spacing offset1 between the last OFDM symbol of the PDCCH where this DCI is located and the first OFDM symbol of the single-slot or multi-slot PDSCH scheduled by this PDCCH is smaller than the first threshold timeDurationForQCL, then the space information of the PDSCH (e.g., TCI state) can be determined according to the following methods (1) and (2) when there are no multiple first identifiers (CORESETPoolIndex) and all activated TCI code points correspond to a single TCI state or QCL.

[0068] (1) If the CORESET associated with the monitored search space of the nearest time unit (e.g., a slot, sub-slot, or multiple OFDM symbols in one or more slots (e.g., SPAN)) corresponds to K distinct TCI states, then the TCI states of this PDSCH are the same as M of these K distinct TCI states, where K is an integer greater than 1 and M is an integer greater than or equal to 1. For example, the nth or nth ~ (n+M-1)th TCI state among the multiple distinct TCI states corresponding to the CORESET associated with the monitored search space of the nearest time unit are the same, where the value of n may be predetermined or agreed upon. Alternatively, the TCI states of this PDSCH are the M TCI states with the strongest signal intensity among these K distinct TCI states.

[0069] (2) If the nearest time unit detection search space relates to multiple CORESETs, the TCI state or QCL of this PDSCH corresponds to the TCI state of the CORESET with the smallest identifier (ID) among these multiple CORESETs. Alternatively, the TCI state of this PDSCH is the M TCI states with the strongest signal intensity among the multiple TCI states corresponding to these multiple CORESETs, where M is an integer of 1 or more. In this possible implementation, it is possible to pre-set or agree that M TCI states are assigned to the CORESET having the smallest identifier. For details, see Table 1. Here, in this embodiment, the target in Table 1 is the PDSCH.

[0070] In this embodiment, if the detected DCI does not indicate a TCI state, and the symbol spacing offset1 between the last OFDM symbol of the PDCCH where the DCI is located and the first OFDM symbol of the single-slot or multi-slot PDSCH scheduled by this PDCCH is greater than or equal to a first threshold timeDurationForQCL, then the TCI state of the PDSCH can be determined according to one of the following methods (1) and (2), provided that there are no multiple first identifiers (CORESETPoolIndex) and each activated TCI code point corresponds to only one TCI state or QCL.

[0071] (1) When the time-frequency resource of the PDCCH where the detected DCI is located is transmitted in FDM or TDM mode according to a certain rule based on a resource granularity, corresponding to different space information, it is determined that the space information of the PDSCH transmitted once or multiple times is one of multiple space information corresponding to the PDCCH (i.e., the PDCCH is the reference resource of the PDSCH). That is, the TCI state of the PDSCH transmitted each time corresponds to one TCI state or QCL in the PDCCH. Alternatively, for the PDSCH transmitted multiple times, it is determined that the space information of the PDSCH transmitted each time corresponds to one of multiple space information corresponding to the PDCCH according to a predetermined rule. For example, alternating or consecutive n transmissions correspond to the same space information. For example, if PDCCH corresponds to TCI state 1 and TCI state 2 respectively according to a certain rule based on a resource granularity, then the space information of the first transmission of a PDSCH transmitted multiple times corresponds to TCI state 1, the space information of the second transmission corresponds to TCI state 2, the space information of the third transmission corresponds to TCI state 1, and so on, alternating between the two.

[0072] (2) When multiple transmissions of the PDCCH in which the detected DCI is located correspond to different space information and are transmitted using SDM, FDM, TDM, or a combination thereof, it is determined that the space information of the PDSCH transmitted once or the PDSCH transmitted multiple times corresponds to the space information of one of the multiple transmissions of the PDCCH, for example, to the space information of the first, nth, or last transmission of the PDCCH, or for the PDSCH transmitted multiple times, it is determined that the space information of the PDSCH transmitted each time corresponds to one of the multiple space information of the PDCCH transmitted multiple times according to a predetermined rule. For example, they correspond alternately. For example, if the TCI state of the first transmission of the PDCCH is TCI state 1 and the TCI state of the second transmission is TCI state 2, then the space information of the first transmission of the PDSCH transmitted multiple times corresponds to TCI state 1, the space information of the second transmission corresponds to TCI state 2, and the space information of the third transmission corresponds to TCI state 1, and so on, they correspond alternately. For details, please refer to Table 1.

[0073] [Table 1]

[0074] In a multi-TRP scenario, control signaling may originate from multiple TRPs and is called multi-TRP, which is scheduled by multi-DCI, i.e., each TRP transmits its own PDCCH, each PDCCH schedules its own PDSCH, AP CSI-RS, PUSCH, or SRS, and multiple CORESETs located in the UE are associated with different RRC parameters CORESETPoolIndex and correspond to different TRPs.

[0075] In this embodiment, when no TCI state is indicated in the detected DCI, or when one TCI state is indicated in the detected DCI, and the symbol spacing offset1 between the last OFDM symbol of the PDCCH where this DCI is located and the first OFDM symbol of the single-slot or multi-slot PDSCH scheduled by this PDCCH is smaller than the first threshold timeDurationForQCL, and when multiple first identifiers (CORESETPoolIndex) are placed in the UE and each activated TCI code point corresponds to only one TCI state or QCL, then the PDSCH space information is similar to that of the case where multiple first identifiers are not placed, the difference being that in such a case, the TCI state or QCL of the PDSCH corresponds to one or more TCI states corresponding to a CORESET belonging to the same CORESETPoolIndex as this PDSCH, associated with the nearest monitored search space for time units. As shown in Table 2, in this embodiment, the target object in Table 2 is the PDSCH.

[0076] [Table 2]

[0077] In a multi-TRP scenario, the control signaling may originate from a single TRP and is called multi-TRP scheduled by a single DCI, i.e., one TRP transmits a PDCCH to schedule one PDSCH, which includes various multi-TRP transmission schemes, such as data on different layers of the PDSCH originating from different TRPs, or data on different frequency domain subcarriers originating from different TRPs, or time domain overlaps of each iteration originating from different TRPs. In such cases, the MAC CE activates at most eight TCI codepoints, where at least one TCI codepoint corresponds to two TCI states. If a TCI codepoint indicated by the TCI field in the detected DCI corresponds to two TCI states and one of the TCI states includes "QCL-TypeD" (i.e., space beam type QCL), it instructs the MAC CE to schedule the PDSCH for the multi-TRP transmission. The specific transmission scheme is determined in other ways, for example, by higher-layer parameters. If the above time offset offset1 is smaller than timeDurationForQCL, the UE may receive the PDSCH using multiple default receive beams, i.e., the UE may consider the DMRS port of the serving cell's PDSCH and two TCI states RS indicated by the code point of the smallest index among two different TCI states to be QCL. This is shown in Table 3.

[0078] Table 3. At least one activated TCI code point corresponds to two TCI states (MTRP for single DCI). [Table 3]

[0079] Furthermore, the target may be a cross-carrier scheduling PDSCH. If a PDCCH transmitting a scheduling DCI is in the first CC, but the PDSCH scheduled by this DCI is in the second CC (where the first and second CCs are different), and the UE is configured to allow the use of the default beam for cross-carrier scheduling, then currently, the above Offset1 is smaller than timeDurationForQCL+Δ1, where Δ1 is a time adjustment value due to the different subcarrier intervals of the two CCs. If the DCI does not include a TCI field, and the TCI state for the PDSCH activated on the activated BWP in the second CC has multiple TCI states, then the QCL from which the UE receives the PDSCH may correspond to one of these multiple TCI states, for example, the first one, or the QCL from which the UE receives the PDSCH may correspond to the one with the strongest signal among the multiple TCI states. In this embodiment, the reference resource is the multiple space information to be activated, specifically the multiple TCI states used for the PDSCH.

[0080] Example 2 In this embodiment, the technical proposal according to the embodiment of this application will be explained using the example that the target is Channel State Information (CSI) and Reference Signal (RS).

[0081] If the CSI-RS is not configured to have parameter repetition "on", and one CSI-RS resource is located in the UE, and this CSI-RS resource is in the same OFDM symbol as one search space associated with one CORESET, then the space information for this CSI-RS may be determined based on this CORESET (i.e., the reference resource). If this CORESET corresponds to multiple TCI states or QCLs, the UE may assume that one of the multiple TCI states or QCLs corresponding to the DMRS of the PDCCH of all search space sets associated with this CSI-RS and this CORESET is QCL-TypeD, and if QCL-TypeD is available, for example, the first TCI state or QCL, or if this CORESET corresponds to one or more TCI states or QCLs with the strongest signal intensity among multiple TCI states or QCLs, the UE may determine that the space information of this CSI-RS corresponds to one or more TCI states or QCLs in this CORESET, and this one or more TCI states or QCLs may be a predetermined one, for example, the first one, or it may be one or more TCI states or QCLs with the strongest signal intensity among multiple TCI states or QCLs corresponding to this CORESET.

[0082] The proposed technology according to this embodiment is also applicable when CSI-RS and CORESET are on different intra-band carriers.

[0083] Example 3 In this embodiment, the technical proposal according to the embodiment of this application will be explained using as an example that the target is an aperiodic CSI-RS (A-CSI-RS) related to a CSI trigger state indicated by DCI.

[0084] In this embodiment, the CSI trigger state indicated by the DCI detected by the UE is associated with A-CSI-RS, where at least one CORESET is located in the BWP where A-CSI-RS is located.

[0085] In this embodiment, if the scheduling offset of the A-CSI-RS is smaller than a second preset value, the space information of the A-CSI-RS is determined by a CORESET placed in the BWP where the A-CSI-RS is located, where the scheduling offset is the number of symbols between the last symbol of the PDCCH transmitting the DCI and the first symbol of the A-CSI-RS resource where no transmission information (trs-Info) in the CSI-RS resource set placement parameters is placed.

[0086] In this embodiment, if there are no multiple CORESETPoolIndexes (i.e., the first identifier) ​​in the UE, and each activated TCI code point corresponds to only one TCI state, and the A-CSI-RS does not have the same OFDM symbol as other downlink signals, and at least one CORESET is located in the BWP where the A-CSI-RS is located, then the space information of the A-CSI-RS can be determined according to methods 1-1-1, 2-1-1, or 2-1-2 in Table 1 above, provided that the scheduling offset offset2 is smaller than a second preset value (i.e., threshold 2). Specifically, this is shown in Table 4.

[0087] [Table 4]

[0088] Here, other downlink signals include PDSCH with a scheduling offset greater than or equal to timeDurationForQCL, periodic CSI-RS (P-CSI-RS), semi-sustained CSI-RS (SP-CSI-RS), and AP-CSI-RS with a scheduling offset greater than or equal to threshold 2.

[0089] Here, if the threshold beamSwitchTiming reported by the UE is one in {14, 28, 48} and enableBeamSwitchTiming-r16 is not placed in the network, then threshold 2 is the threshold beamSwitchTiming reported by the UE; if the threshold beamSwitchTiming reported by the UE is one in {224, 336} and enableBeamSwitchTiming-r16 is not placed in the network, then threshold 2 is 48. If the PDCCH triggering A-CSI-RS and A-CSI-RS have different subcarrier intervals (e.g., cross-carrier scheduling may occur), then threshold 2 is beamSwitchTiming + Δ2 (where Δ2 is the time adjustment value for the different subcarrier intervals).

[0090] When multiple CORESETPoolIndexes (i.e., the first identifier) ​​are assigned to a UE and an MTRP scheduled by multi-DCI is adopted, In this embodiment, if the A-CSI-RS does not have the same OFDM symbol as other downlink signals, and at least one CORESET is located in the BWP where the A-CSI-RS is located, then the space information of the A-CSI-RS can be determined according to methods 1-1-1, 2-1-1, or 2-1-2 in Table 1, where the CORESET in Table 1 is the CORESET corresponding to the same first identifier as the target object (the A-CSI-RS in this embodiment).

[0091] Example 4 In this embodiment, the technical proposal according to the embodiment of this application will be explained using the example that the target object is a PUCCH.

[0092] One UE, (1) Reports on beamCorrespondenceWithoutUL-BeamSweeping, and (2) pathlossReferenceRSs is not placed in PUCCH-PowerControl, and (3) enableDefaultBeamPlForPUCCH is placed and (4) If PUCCH-SpatialRelationInfo is not placed, The space information (space relationship) from which this UE transmits PUCCH is determined based on the space information corresponding to the reference resource, where the reference resource includes a first target CORESET, and the first target CORESET is the CORESET with the smallest identifier on the downlink BWP that is activated for the cell transmitting the PUCCH.

[0093] In this embodiment, determining that the first space information of the target object corresponds to the target space information may include one of the following:

[0094] (1) The first space information of a PUCCH transmitted once or multiple times is determined to correspond to the target space information, and for example, for a single PUCCH transmission or multiple PUCCH transmissions, the space relationship for transmitting a PUCCH corresponds to one of the multiple TCI states or QCLs corresponding to the CORESET, and for example, the first TCI state or multiple TCI states corresponds to a TCI state with a relatively strong signal.

[0095] (2) For PUCCH transmitted multiple times, the first space information of each transmitted PUCCH is determined to correspond to one of the multiple space information of the first target CORESET according to a predetermined rule. For example, for repeated transmission of multiple PUCCHs, the space relationship for each PUCCH transmission corresponds to one of the multiple TCI states or QCLs corresponding to the CORESET according to the rule, and they correspond, for example, alternately.

[0096] Example 5 In this embodiment, the technical proposal according to the embodiment of this application will be explained using the example that the target object is a PUSCH.

[0097] In one possible implementation of this embodiment, if the detected DCI is DCI format 0_0, then because the uplink scheduling DCI format 0_0 does not contain a PUSCH transmit space relation instruction (SRI), the space relation of the PUSCH scheduled by DCI format 0_0 is determined based on space information corresponding to the target PUCCH resource (i.e., the reference resource of the PUSCH) on the uplink BWP activated by the cell transmitting the PUSCH, where the target PUCCH resource is the PUCCH resource having the smallest identifier on the uplink BWP activated by this cell. In such a case, determining that the first space information of the target corresponds to the target space information may include any one of the following:

[0098] (1) Determine one of the first space information of a PUSCH transmitted once or multiple times, and one of the multiple second space information corresponding to the target PUSCH resource, and the space relationship for transmitting a single PUSCH or multiple PUSCHs corresponds to one of the multiple space relationships of this target PUSCH resource, for example, the first one or one of the pre-configured ones, (2) For PUSCH transmitted multiple times, the first space information of each transmitted PUSCH is determined to correspond to one of a plurality of second space information corresponding to the target PUSCH resource, according to a predetermined rule. For example, when transmitting multiple PUSCHs, the space relationship of each PUSCH transmission opportunity corresponds to one of a plurality of space relationships of this PUSCH resource, according to the rule, and they correspond, for example, alternately.

[0099] In another possible embodiment of this embodiment, if the UE upper layer parameter enableDefaultBeamPlForPUSCH0_0 in the RRC connection state is set to "enabled", and no PUCCH resource is located on the uplink BWP to be activated, or none of the PUCCH resources located on the uplink BWP to be activated have a space relationship, then the reference resource for the PUSCH includes a second target CORESET, and the second target CORESET is the CORESET with the smallest identifier on the downlink BWP to be activated of the CC or cell transmitting the PUSCH, and if the CORESET with the smallest identifier corresponds to multiple TCI states, then determining that the first space information of the target corresponds to the target space information includes one of the following:

[0100] (1) The first space information of a PUSCH transmitted once or multiple times is determined to correspond to the target space information, and for example, for a single PUSCH transmission or multiple PUSCH transmissions, the space relationship for transmitting a PUSCH corresponds to one of the multiple TCI states or QCLs corresponding to the second CORESET, and for example, the first TCI state or multiple TCI states corresponds to a TCI state with a relatively strong signal.

[0101] (2) For PUSCH transmitted multiple times, the first space information of each transmitted PUSCH is determined to correspond to one of the multiple space information of the second target CORESET according to a predetermined rule. For example, for repeated PUSCH transmissions, the space relationship for each PUSCH transmission corresponds to one of the multiple TCI states or QCLs corresponding to the second CORESET according to the rule, for example, alternatingly.

[0102] Example 6 In this embodiment, the technical proposal according to the embodiment of this application will be explained using the example that the target is a Sounding Reference Signal (SRS).

[0103] UE, (1) The upper-level parameter enableDefaultBeamPlForSRS is set to "Enabled", and (2) The parameter usage in SRS-ResourceSet is set to "beamManagement" or {set to "nonCodebook" and associatedCSI-RS is placed} or SRS-PosResourceSet-r16 is placed in the SRS resource, and the higher-level parameter spatialRelationInfo is not placed in FR2, (3) There are no multiple CORESETPoolIndex values ​​with different values ​​(it is not an MTRP scheduled by multiple DCIs), and (4) If the TCI codebook containing two corresponding TCI states is not in place (i.e., not an MTRP scheduled by a single DCI), The spatial relationship of the aforementioned SRS is determined based on the smallest CORESET (i.e., the third target CORESET) of the identifiers on the uplink BWP activated on the carrier or cell transmitting the SRS, and if the third target CORESET corresponds to multiple TCI states or QCLs, determining that the first spatial information of the target corresponds to the target spatial information may include any one of the following:

[0104] (1) A space relationship that transmits one SRS resource, or a space relationship that transmits one SRS resource multiple times, or a space relationship that transmits multiple SRS resources corresponds to a reference signal (RS) having "QCL-TypeD", and if QCL-TypeD is available, this RS corresponds to one of the multiple TCI states or QCLs corresponding to the third target CORESET, for example, the first TCI state, or to the TCI state with the strongest signal among the multiple TCI states.

[0105] (2) The space relationships for each repeated transmission of an SRS in multiple repeated transmissions of a single SRS resource, or the space relationships for transmitting each SRS resource in multiple SRS resources, correspond to RS having "QCL-TypeD" according to the rules, and if QCL-TypeD is available, each RS corresponds to one of multiple TCI states or QCLs corresponding to the third target CORESET according to the rules, for example, alternating between each other.

[0106] Example 7 In this embodiment, the technical proposal according to the embodiment of this application will be explained using CORESET#0 as an example.

[0107] In a CORESET, CORESET#0 may have different characteristics from other CORESETs. For example, CORESET#0 may be provided by the portion of the Master Information Block (MIB) transmitted over a Physical Broadcast Channel (PBCH) that is configured as the initial bandwidth portion (BWP). CORESET#0 may also be a CORESET for monitoring a Physical Downlink Link Control Channel (PDCCH) for scheduling a Physical Downlink Link Shared Channel (PDSCH) on which a System Information Block (SIB1) is carried, and may be used to receive other system information and additional configuration information. Alternatively, another CORESET may be provided by dedicated RRC signaling, and this CORESET can be used to receive specific control information of the UE. Furthermore, CORESET#0 may not have an explicit setting for the TCI state. Therefore, it is necessary to determine the space information for CORESET#0. Since the TCI state of CORESET#0 is related to a reference signal associated with the synchronization signal / physical broadcast channel block (SSB, which may also be called the synchronization signal block), the TCI state of CORESET#0 is determined based on the space information corresponding to the SSB (i.e., the reference resource).

[0108] Multiple spatial information is placed in the search space (i.e., SS#0) of CORESET#0. For example, multiple tracking reference signals (TRS) are placed in SS0, and each TRS is associated with one SSB. Different TRS are associated with different SSBs, but different SSBs have different spatial information. In such a case, the reference resource (i.e., SSB) of CORESET#0 corresponds to multiple spatial information. In this embodiment, it is determined that the spatial information of CORESET#0 (e.g., TCI state or QCL) corresponds to the spatial information of one of the SSBs, for example, a pre-specified SSB. When the UE detects this SSB, it can determine that the spatial information of CORESET#0 corresponds to the spatial information of this SSB based on the spatial information of this SSB (e.g., the received beam).

[0109] It should be explained that while terminals are used as examples in each of the above embodiments, the network-side equipment can employ a method corresponding to the terminal, determine the first space information of the target object, and transmit the target object based on the first space information. Further explanation is not provided for the embodiments of this application.

[0110] Figure 3 shows a flowchart of a method for determining a detection opportunity in an embodiment of the present application, and this method 300 may be performed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in Figure 3, this method may include the following steps.

[0111] In S310, if multiple space relationships are placed in a search space associated with CORESET#0, and the multiple space relationships correspond to multiple synchronization signal blocks, and different synchronization signal blocks correspond to different space relationships, the terminal determines the detection opportunity for the search space based on one of the synchronization signal blocks, or determines multiple detection opportunities for the search space based on the multiple synchronization signal blocks.

[0112] For example, when a terminal detects a single synchronization signal block, it may determine the opportunity to detect the search space of CORESET#0 based on the detected synchronization signal block, and then detect CORESET#0 at the appropriate opportunity. Alternatively, the terminal may determine multiple opportunities to detect the search space of CORESET#0 based on multiple detected SSBs.

[0113] In one possible implementation, a terminal determining a search space detection opportunity based on one of the synchronization signal blocks includes determining the time-frequency resources and space relationships of the search space detection opportunity based on the one of the synchronization signal blocks, and determining multiple detection opportunities of the search space based on multiple synchronization signal blocks includes determining the time-frequency resources and space relationships of the multiple detection opportunities of the search space based on the multiple synchronization signal blocks. That is, in this possible implementation, determining a search space detection opportunity includes determining the time-frequency resources and space relationships of the detection opportunity.

[0114] For non-broadcast PDCCH, the network-side equipment and the UE have the same understanding of SSB / CORESET#0 / SS#0 in connection mode. Therefore, in this embodiment, the detection opportunity for SS#0 of CORESET#0 can be determined based on the detected SSB. If multiple SSBs are deployed, one detection opportunity may be determined based on one of the SSBs, or multiple detection opportunities may be determined based on multiple SSBs.

[0115] The detection opportunity determination method according to the embodiment of this application allows for the determination of a detection opportunity for the search space based on one of the synchronization signal blocks, or for determining multiple detection opportunities for the search space based on the multiple synchronization signal blocks, when a plurality of space relationships are arranged in a search space associated with CORESET#0, and the plurality of space relationships correspond to a plurality of synchronization signal blocks, and different synchronization signal blocks correspond to different space relationships.

[0116] It should be explained that, in the transmission method according to the embodiment of this application, the execution body may be a transmission device or a control module for executing the transmission method in this transmission device. In the embodiment of this application, the transmission device according to the embodiment of this application will be described as an example in which the transmission device executes the transmission method.

[0118] In embodiments of this application, the first determination module 401 is used to determine that the first space information of a target corresponds to target space information when the first space information of a target is determined based on second space information corresponding to a reference resource, wherein the reference resource corresponds to a plurality of second space information, and the target space information is one or more of the plurality of second space information, and the transmission module 402 is The first spatial information determined is used to transmit the target object.

[0122] In one possible implementation, the target object has multiple transmission resources, and the first spatial information used for transmitting the target object on different transmission resources corresponds to a plurality of second spatial information contained in the target spatial information according to a mapping rule, wherein the plurality of transmission resources include at least one of a plurality of time-division multiplexing transmission resources, a plurality of frequency-division multiplexing transmission resources, a plurality of spatial-division multiplexing transmission resources, and a plurality of code-division multiplexing transmission resources.

[0123] In one possible implementation, the target object has one or more transmission resources, and the target space information is one of a plurality of the second space information.
