Description

[Technical Field]

[0001] The present application belongs to the technical field of wireless communication, and specifically relates to a transmission method, a communication device and a readable storage medium. [Background technology]

[0002] In the related art, in some cases, the space information of a certain uplink / downlink channel or uplink / downlink signal needs to be determined based on the space information of a reference resource, mainly including: when reception of the space information of the downlink channel or downlink signal is not configured, activated or indicated, and in other cases that cannot be determined, the space information used for these downlink channels or downlink signals is received, where the downlink channel includes a physical downlink shared channel (PDSCH) or a PDSCH scheduled by a component carrier (CC), and the downlink signal includes an aperiodic channel state information reference signal (Aperiodic The AP transmits space information used for uplink channels and uplink signals when the transmission of space information for these uplink channels and uplink signals is not configured, activated, or indicated, and when it cannot be determined otherwise, the uplink channels include a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), and the like, and the uplink signals include a Sounding Reference Signal (SRS). In the above case, the downlink channel, space information for receiving the downlink signal, the uplink channel, space information for transmitting the uplink signal generally correspond to space information of the reference resource, where the reference resource may be a control resource set (CORESET), a physical downlink control channel (PDCCH) for scheduling the downlink channel / signal, the uplink channel / signal, or other channels / signals.

[0003] For example, if the higher layer parameter tci-PresentInDCI configured in one CORESET for one terminal (User Equipment, UE) is set to "enabled," the UE considers that Downlink Control Information (DCI) format 1_1 or DCI format 1_2 in the PDCCH transmitted on this CORESET includes a Transmission Configuration Indication (TCI) field, which is used to indicate information including a spatial receive beam, such as the TCI state. Only when the UE detects the DCI can it then correctly decode the TCI state and determine the receive beam to be used to receive the PDSCH scheduled by this PDCCH. It takes a certain time for the UE to detect the DCI and switch beams based on the TCI indication. If DCI format 1_1 indicates a time offset for scheduling the PDSCH, and the symbol interval between the last symbol of the PDCCH where the DCI is located and the first symbol of the single-slot or multi-slot PDSCH it schedules is greater than or equal to the threshold timeDurationForQCL, the UE may receive the PDSCH of the serving cell according to the receiving beam indicated by the TCI field in this DCI. That is, the Demodulation Reference Signal (DMRS) port of the single-slot or multi-slot PDSCH and the Reference Signal (RS) of the TCI state indicated by the TCI field may be considered to be Quasi Co-Located (QCL).When the upper layer parameter tci-PresentInDCI configured in one CORESET is set to "enabled" or the upper layer parameter tci-PresentInDCI is not configured, if all TCI code points activated by the control unit (Control Element, CE) of the medium access control layer (MAC) are mapped as one TCI state and the above time offset is smaller than timeDurationForQCL, then the UE has not completed DCI detection or has not completed the receive beam switching operation, and the UE may cache the received signals on these symbols using the default receive beam, thereby facilitating demodulation of the scheduled PDSCH after successful DCI detection. The UE may receive the PDSCH using a default receiving beam, i.e., the UE may consider the RS in the DMRS port of the PDSCH of the serving cell and the QCL parameter for the PDCCH QCL indication in the CORESET to be the QCL, where this CORESET is the CORESET with 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 of a certain uplink / downlink channel or uplink / downlink signal may correspond to multiple space information, and in such a case, the communication device cannot determine the space information of the uplink / downlink channel or uplink / downlink signal. For example, in a scenario of multiple transmission and reception points (TRPs), as an implementation method for enhancing the reliability of the control channel, the PDCCH is transmitted through multiple TRPs to reduce the probability of beam link failure. In such a case, the PDCCH may correspond to multiple TCI states or QCLs. When the UE considers that the RS in the DMRS port of the PDSCH of the serving cell and the QCL parameter for the PDCCH QCL indication in the CORESET is QCL, the PDCCH corresponds to multiple different TCI states or QCLs, and therefore the UE cannot determine the space information for receiving the PDSCH.

[0021] The following describes in detail the transmission method according to the embodiments of the present application through specific examples and application scenarios in conjunction with the drawings.

[0022] 2 shows a flowchart of a transmission method in an embodiment of the present application, where the method 200 may be performed by a communication device. In other words, the method may be performed by software or hardware installed in the communication device. As shown in FIG. 2, the method may include the following steps:

[0023] At S210, when the first space information of the target object is determined based on second space information corresponding to a reference resource, the communication device determines that the first space information of the target object corresponds to 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 an embodiment of the present application, the first space information of the target object is determined based on the second space information corresponding to the reference resource, which means that the first space information of the target object cannot adopt the space information indicated in the downlink control information, or the first space information of the target object is not indicated in the downlink control information. For example, if the upper layer parameter tci-PresentInDCI configured on one CORESET is set to "enabled", the DCI in the PDCCH transmitted on this CORESET adopts DCI format 1_1 (DCI format 1_1) or DCI format 1_2 (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), the first space information of the target object (the PDSCH at this time) is determined based on the second space 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, a subslot, or multiple OFDM symbols in one slot or multiple slots (e.g., SPAN)).

[0025] In an embodiment of the present application, the reference resource corresponding to multiple second space information includes that there is one reference resource corresponding to the target object, and this reference resource corresponds to multiple second space information, or that there are multiple reference resources corresponding to the target object, that is, the reference resource includes multiple sub-reference resources, and each sub-reference resource corresponds to one or more second space information.

[0026] For example, taking the reference resource as a PDCCH or a search space, in practical application, the PDCCH may be transmitted by adopting one of the following schemes (1) and (2):

[0027] (1) The time-frequency resources of one PDCCH or search space correspond to different second space information according to a certain rule based on a certain resource granularity, and are transmitted in a frequency division multiplex (FDM) or time division multiplex (TDM) manner. Here, the resource granularity may be a control channel element (CCE), a resource element group (REG), a REG bundle, a precoding granularity, a PDCCH candidate, a search space detection opportunity, etc.

[0028] (2) Different second space information corresponding to multiple transmissions of one PDCCH is transmitted by spatial division multiplexing (SDM), FDM, TDM, or a combination thereof.

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

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

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

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

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

[0034] In another possible implementation manner, the terminal is configured so that multiple search spaces are used to transmit the same PDCCH, and the multiple search spaces corresponding to multiple second space information includes at least one of the following (1) and (2).

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

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

[0037] At least two pieces of second space information corresponding to the PDCCH, search space, or CORESET may belong to the same TRP. In a multiple TRP (MTRP) scenario, at least two pieces of second space information corresponding to the PDCCH, search space, or CORESET may belong to different TRPs.

[0038] In an embodiment of the present application, the target space information may be one or more of a plurality of second space information, and whether it is one or more may be determined in advance, agreed upon, or based on actual scheduling. For example, if there is a plurality of space information indicated in the DCI for scheduling the downlink channel / downlink signal or the uplink channel / uplink signal, the target space information may be a plurality of the second space information, or if there is a plurality of second space information for configuring and / or activating the reference resource, the target space information may be a plurality of the second space information.

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

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

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

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

[0043] Alternatively, in another possible implementation manner, if the reference resource includes multiple sub-reference resources, the target space information is one or more pieces of second space information with the strongest signal strength among multiple pieces of second space information 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 certain space information or the RS quality transmitted using certain space information.

[0044] In one possible transmission method, the target object may have multiple transmission resources, and the first space information adopted for transmitting to the target object on different transmission resources may correspond to multiple second space information included in the target space information according to a mapping rule, where the multiple transmission resources include at least one of multiple transmission resources of time division multiplexing, multiple transmission resources of frequency division multiplexing, multiple transmission resources of space division multiplexing, and multiple transmission resources of code division multiplexing.

[0045] For example, when a target object is transmitted at a different frequency, the first space information adopted for the transmission of the target object at the different frequency may correspond to a plurality of second space information included in the target space information according to a predetermined mapping rule. For example, when the plurality of second space information included in the target space information is space information 1 and space information 2, and the target object is transmitted on frequency-domain orthogonal subcarrier group 1 and subcarrier group 2, it can be determined according to the mapping rule that the first space information adopted by the target object in subcarrier group 1 corresponds to space information 1, and the first space information adopted by the target object in subcarrier group 2 corresponds to space information 2.

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

[0047] Alternatively, when a target object is transmitted on different spatial domain resources (e.g., different layers of MIMO), the first space information adopted for transmission of the target object in different spaces may correspond to multiple pieces of second space information included in the target space information according to a preset mapping rule. For example, when the multiple pieces of second space information included in the target space information are space information 1 and space information 2 and the target object is transmitted on layer 1 and layer 2, it can be determined according to the mapping rule that the first space information adopted by the target object on layer 1 corresponds to space information 1, and the first space information adopted on layer 2 corresponds to space information 2.

[0048] Or, in another possible transmission method, the target object has one transmission resource or multiple transmission resources, and the target space information is one of the multiple second space information, that is, in this possible implementation method, even if the target object has multiple transmission resources, the first space information adopted for transmission on each transmission resource corresponds to the same second space information, that is, the first space information adopted for transmission on each transmission resource is the same.

[0049] In each of the above possible implementations, if multiple first identifiers are configured in a terminal transmitting a 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 generally used to identify a TRP. The network may configure multiple CORESETs associated with different CORESETPoolIndex values ​​in the terminal 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, i.e., in this possible implementation, the first space information of the target object corresponds to the second space information of the reference resource in the same time unit.

[0051] In the above possible implementation manner, one time unit may be one slot, or a portion of Orthogonal Frequency Division Multiplexing (OFDM) symbols in one slot, or multiple slots, or a portion of OFDM symbols in multiple slots, and this embodiment does not specifically limit it.

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

[0053] In one possible implementation manner, the reference resource includes any one of a CORESET, a search space, a PDCCH for scheduling the target object, a Physical Uplink Control Channel (PUCCH), space information to be configured and / or activated, and a Synchronization Signal and PBCH block (SSB).

[0054] In one possible implementation, the first spatial information includes one of a TCI state, a QCL, and a spatial relation.

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

[0056] In S212, the determined first space information is adopted to transmit to the target object.

[0057] In an embodiment of the present 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 (for example, PDSCH), the communication device may be a network side device or a terminal, and if the network side device, it will adopt first space information corresponding to target space information to transmit this downlink channel, and if the terminal, it will adopt first space information corresponding to target space information to receive this downlink channel.

[0058] Hereinafter, taking a terminal as an example, the technical solutions according to the embodiments of the present application will be described according to different target objects.

[0059] Example 1 In this embodiment, the target object is PDSCH as an example to describe the technical solution according to the embodiment of the present application.

[0060] In this embodiment, when the PDCCH in which the DCI detected by the UE is located corresponds to multiple TCI states, the TCI state of the PDSCH is not indicated in the DCI, for example, the detected DCI is DCI format 1_0, or the detected DCI is DCI format 1_1 or DCI in which tci-PresentInDCI is not located. If the format is 1_2, or if the detected DCI indicates one TCI state but the symbol interval between the last OFDM symbol of the PDCCH in which 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), the TCI state or QCL of the PDSCH scheduled by this PDCCH is determined based on the TCI state or QCL corresponding to the reference resource (a predetermined CORESET, i.e., the CORESET associated with the detection search space of the nearest time unit).

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

[0062] Therefore, the PDCCH in which the DCI detected by the UE is located may correspond to a plurality of TCI states, including, but not limited to, the following 1) to 4).

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

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

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

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

[0067] In this embodiment, when the detected DCI does not indicate a TCI state or indicates one TCI state, if the symbol interval offset1 between the last OFDM symbol of the PDCCH in which 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 timeDurationForQCL, and when multiple first identifiers (CORESETPoolIndex) are not configured and all of the activated TCI code points correspond to one TCI state or QCL, the PDSCH space information (e.g., TCI state) can be determined according to the following methods (1) and (2).

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

[0069] (2) If the closest time unit detection search space is associated with multiple CORESETs, the TCI state or QCL of this PDSCH corresponds to the TCI state corresponding to the CORESET with the smallest identifier (ID) among these multiple CORESETs. Or, the TCI state of this PDSCH is M TCI states with the strongest signal strength among the multiple TCI states corresponding to these multiple CORESETs, where M is an integer equal to or greater than 1. In this possible implementation, it may be preset or agreed that the M TCI states are arranged in the CORESET with the smallest identifier. For details, see Table 1. In this embodiment, the target object in Table 1 is the PDSCH.

[0070] In this embodiment, if the detected DCI does not indicate a TCI state, and the symbol interval offset1 between the last OFDM symbol of the PDCCH in which this DCI is located and the first OFDM symbol of the single-slot or multi-slot PDSCH scheduled by this PDCCH is equal to or greater than a first threshold timeDurationForQCL, and if multiple first identifiers (CORESETPoolIndex) are not configured and all activated TCI codepoints correspond to only one TCI state or QCL, the TCI state of the PDSCH can be determined according to one of the following methods (1) and (2).

[0071] (1) When the time-frequency resource of the PDCCH in which the detected DCI is located corresponds to different space information according to a certain rule based on a certain resource granularity and is transmitted in an FDM or TDM manner, the space information of the PDSCH transmitted once or the PDSCH transmitted multiple times is determined to be 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, the space information of the PDSCH transmitted each time is determined to correspond 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 the PDCCH corresponds to TCI state 1 and TCI state 2 according to a certain rule based on a certain resource granularity, the space information of the first transmission of the PDSCH, which is 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, alternating in this manner.

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

[0073] [Table 1]

[0074] In a multi-TRP scenario, the control signaling may come from multiple TRPs, referred to as multi-TRP scheduled by multiple DCI, i.e., each TRP transmits a respective PDCCH, each PDCCH schedules a respective 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 the detected DCI does not indicate a TCI state or indicates one TCI state, if the symbol interval offset1 between the last OFDM symbol of the PDCCH in which the 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 timeDurationForQCL, and multiple first identifiers (CORESETPoolIndex) are configured in the UE and each activated TCI codepoint corresponds to only one TCI state or QCL, the space information of the PDSCH is similar to that when multiple first identifiers are not configured, except that in this 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, which is associated with the nearest time unit detection search space (monitored search space). 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, control signaling may be from one TRP, referred to as multi-TRP scheduled by a single DCI. That is, one TRP transmits a PDCCH to schedule one PDSCH, and the PDSCH includes various multi-TRP transmission schemes, such as: data on different layers of the PDSCH from different TRPs, data on different frequency domain subcarriers from different TRPs, or time domain overlapping each time 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 the TCI codepoints indicated in the TCI field in the detected DCI correspond to two TCI states and one TCI state is indicated to include "QCL-Type D" (i.e., space beam type QCL), the MAC CE indicates that the PDSCH for the multi-TRP transmission should be scheduled. The specific transmission scheme is determined in other manners, for example, configured in higher layer parameters. If the time offset offset1 is smaller than timeDurationForQCL, the UE may receive the PDSCH using multiple default receiving beams, i.e., the UE may consider the DMRS port of the PDSCH of the serving cell and the two TCI state RSs indicated by the codepoint with the smallest index among the codepoints containing two different TCI states as QCL, as shown in Table 3.

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

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

[0080] Example 2 In this embodiment, the target object is a Channel State Information (CSI) Reference Signal (RS) as an example to describe the technical solution according to the embodiment of the present application.

[0081] If the CSI-RS is not configured with parameter repetition set to "on", and one CSI-RS resource is configured in the UE and this CSI-RS resource is in the same OFDM symbol or symbols as a search space associated with a CORESET, the space information of this CSI-RS may be determined based on this CORESET (i.e., reference resource). If this CORESET corresponds to multiple TCI states or QCLs, the UE may assume that this CSI-RS and one of the multiple TCI states or QCLs corresponding to the DMRS of the PDCCH of all search space sets associated with this CORESET are QCL-Type D. If QCL-Type D 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 strength among the 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 pre-specified, for example the first one, or may be one or more TCI states or QCLs with the strongest signal strength among the multiple TCI states or QCLs corresponding to this CORESET.

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

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

[0084] In this embodiment, the CSI trigger state indicated in the DCI detected by the UE is related to the A-CSI-RS, and at least one CORESET is configured in the BWP where the 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 configured 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 carrying the DCI and the first symbol of the A-CSI-RS resource where transmission information (trs-Info) is not configured in the CSI-RS resource set configuration parameters.

[0086] In this embodiment, when multiple CORESETPoolIndexes (i.e., the first identifiers) are not configured in a UE, and each activated TCI codepoint corresponds to only one TCI state, the A-CSI-RS does not have the same OFDM symbol as other downlink signals, and at least one CORESET is configured in the BWP where the A-CSI-RS is located, if the scheduling offset offset2 is smaller than a second preset value (i.e., threshold 2), the space information of the A-CSI-RS can be determined according to scheme 1-1-1, 2-1-1, or 2-1-2 in Table 1. This is specifically shown in Table 4.

[0087] [Table 4]

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

[0089] Here, if the threshold beamSwitchTiming reported by the UE is one in {14, 28, 48} and enableBeamSwitchTiming-r16 is not configured in the network, threshold2 is the threshold beamSwitchTiming reported by the UE, and if the threshold beamSwitchTiming reported by the UE is one in {224, 336} and enableBeamSwitchTiming-r16 is not configured in the network, threshold2 is 48. If the PDCCH that triggers the A-CSI-RS and the A-CSI-RS have different subcarrier spacings (e.g., when cross-carrier scheduling is possible), threshold2 is beamSwitchTiming+Δ2 (Δ2 is the time adjustment value for the different subcarrier spacings).

[0090] When multiple CORESETPoolIndexes (i.e., the first identifiers) are configured in the UE and MTRP scheduled by multiple DCIs 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 configured in the BWP where the A-CSI-RS is located, and if the scheduling offset (offset2) is smaller than a second preset value (i.e., threshold 2), then the space information of the A-CSI-RS can be determined according to schemes 1-1-1, 2-1-1, or 2-1-2 in Table 1 above, where 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 target object is taken as an example to describe the technical solution according to the embodiment of the present application.

[0092] One UE, (1) beamCorrespondenceWithoutUL-BeamSweeping is reported, and (2) pathlossReferenceRSs is not configured in PUCCH-PowerControl, and (3) enableDefaultBeamPlForPUCCH is placed, and (4) If PUCCH-SpatialRelationInfo is not placed, The space information (space relationship) for this UE to transmit the 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 activated downlink BWP of 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) Determine that the first space information of a PUCCH transmitted once or a PUCCH transmitted multiple times corresponds to the target space information, for example, for one PUCCH transmission or multiple PUCCH transmissions, the space relationship for transmitting the PUCCH corresponds to one TCI state or QCL among multiple TCI states or QCLs corresponding to the above CORESET, for example, the first TCI state or multiple TCI states corresponds to a TCI state in which the signal is relatively strong.

[0095] (2) For a PUCCH that is transmitted multiple times, determine that the first space information of the PUCCH that is transmitted each time corresponds to one of the multiple space information of the first target CORESET according to a predetermined rule. For example, for multiple PUCCH repeated transmissions, the space relationship of each PUCCH transmission corresponds to one TCI state or QCL among the multiple TCI states or QCLs that correspond to the CORESET according to a rule, for example, alternately.

[0096] Example 5 In this embodiment, the target object is PUSCH as an example to describe the technical solution according to the embodiment of the present application.

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

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

[0099] In another possible embodiment of this embodiment, when the UE upper layer parameter enableDefaultBeamPlForPUSCH0_0 in the RRC connected state is set to 'enabled', and no PUCCH resource is configured in the activated uplink BWP or no space relationship is configured for any of the PUCCH resources configured on the activated uplink BWP, the reference resource of the PUSCH includes a second target CORESET, and the second target CORESET is the CORESET with the smallest identifier on the activated downlink BWP of the CC or cell transmitting the PUSCH, and when this CORESET with the smallest identifier corresponds to multiple TCI states, determining that the first space information of the target object corresponds to the target space information includes any one of the following:

[0100] (1) Determine that the first space information of the PUSCH transmitted once or the PUSCH transmitted multiple times corresponds to the target space information, for example, for one PUSCH transmission or multiple PUSCH transmissions, the space relationship for transmitting the PUSCH corresponds to one TCI state or QCL among multiple TCI states or QCLs corresponding to the second CORESET, for example, the first TCI state or multiple TCI states corresponds to a TCI state in which the signal is relatively strong.

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

[0102] Example 6 In this embodiment, the target object receives a sounding reference signal. The technical solutions according to the embodiments of the present application will be described using a SRS (Signal Reference Signal) as an example.

[0103] UE, (1) The upper layer parameter enableDefaultBeamPlForSRS is set to "enabled", and (2) The parameter usage in the SRS-ResourceSet is set to “beamManagement” or {set to “nonCodebook” and associatedCSI-RS is configured}, or the SRS resource is configured with SRS-PosResourceSet-r16, and the upper layer parameter spatialRelationInfo is not configured in FR2, and (3) Multiple different values ​​of CORESETPoolIndex are not configured (MTRP is not scheduled by multiple DCIs), and (4) If the TCI codebook including the corresponding two TCI states is not configured (the MTRP is not scheduled by a single DCI), The spatial relationship of the SRS is determined based on the CORESET (i.e., the third target CORESET) with the smallest identifier on the uplink BWP activated on the carrier or cell transmitting this SRS, and if the third target CORESET corresponds to multiple TCI states or QCLs, determining that the first spatial information of the target object corresponds to the target spatial information may include any one of the following:

[0104] (1) The space relationship for transmitting one SRS resource, or the space relationship for repeatedly transmitting one SRS resource multiple times, or the space relationship for transmitting multiple SRS resources corresponds to a reference signal (RS) having “QCL-Type D”, and if QCL-Type D is available, this RS corresponds to one of multiple TCI states or QCLs corresponding to the third target CORESET, for example, the first TCI state, or the TCI state with the strongest signal among the multiple TCI states.

[0105] (2) The spatial relationship of each SRS repeated transmission among multiple repeated transmissions of one SRS resource or the spatial relationship of transmitting each SRS resource among multiple SRS resources corresponds to an RS having “QCL-Type D” according to the rule, and if QCL-Type D is available, each RS corresponds to one of multiple TCI states or QCLs corresponding to the third target CORESET according to the rule, for example, alternately.

[0106] Example 7 In this embodiment, the target object is CORESET#0 as an example to describe the technical solution according to the embodiment of the present application.

[0107] Among CORESETs, CORESET#0 may have different characteristics from other CORESETs. For example, CORESET#0 may be provided by a portion configured as the initial bandwidth portion (BWP) of the master information block (MIB) transmitted on the physical broadcast channel (PBCH). CORESET#0 may be a CORESET for monitoring the physical downlink control channel (PDCCH) for scheduling the physical downlink shared channel (PDSCH) carrying the system information block (SIB1), and may be used to receive other system information and additional configuration information. On the other hand, another CORESET may be provided by dedicated RRC signaling, and this CORESET can be used to receive UE-specific control information. Also, CORESET#0 may not have an explicit configuration for the TCI state. Therefore, the space information for CORESET#0 needs to be determined. Since the TCI state of CORESET#0 is related to a reference signal associated with a synchronization signal / physical broadcast channel block (SSB, which may also be called a synchronization signal block), the TCI state of CORESET#0 is determined based on space information corresponding to the SSB (i.e., reference resource).

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

[0109] It should be noted that the above embodiments use a terminal as an example, but are not limited thereto. The network side equipment can adopt a method corresponding to the terminal to determine the first space information of the target object, and transmit to the target object based on the first space information. No further specific description will be given in the embodiments of this application.

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

[0111] In S310, multiple space relationships are arranged in a search space associated with CORESET#0, and when the multiple space relationships correspond to multiple synchronization signal blocks and different synchronization signal blocks correspond to different space relationships, the terminal determines a 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 one synchronization signal block, the terminal may determine a detection opportunity for the search space of CORESET#0 based on the detected synchronization signal block and detect CORESET#0 at the corresponding detection opportunity. Alternatively, the terminal may determine multiple detection opportunities for the search space of CORESET#0 based on multiple detected SSBs.

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

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

[0115] According to the method for determining detection opportunities in the embodiments of the present application, when multiple space relationships are arranged 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 detection opportunity for the search space can be determined based on one of the synchronization signal blocks, or multiple detection opportunities for the search space can be determined based on the multiple synchronization signal blocks.

[0116] It should be noted that, for the transmission method according to the embodiment of the present application, the execution body may be a transmission device or a control module for executing the transmission method in the transmission device. In the embodiment of the present application, the transmission device according to the embodiment of the present application will be described by taking the transmission method executed by the transmission device as an example.

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

[0122] In one possible implementation manner, the target object has a plurality of transmission resources, and the first space information adopted for transmission to the target object on different transmission resources corresponds to a plurality of the second space information included in the target space information according to a mapping rule, where the plurality of transmission resources include at least one of a plurality of transmission resources of time division multiplexing, a plurality of transmission resources of frequency division multiplexing, a plurality of transmission resources of space division multiplexing, and a plurality of transmission resources of code division multiplexing.

[0123] In one possible implementation manner, the target object has one transmission resource or multiple transmission resources, and the target space information is one of the multiple pieces of second space information.

[0124] In one possible implementation manner, when multiple first identifiers are configured in the terminal transmitting the target object, the reference resource and the target object correspond to the same first identifier.

[0125] In one possible implementation, the reference resource and the target object are located in the same time unit.

[0128] In one possible implementation manner, the reference resource includes any one of a CORESET, a search space, a PDCCH scheduling the target object, a PUCCH, space information to be configured and / or activated, and an SSB.

[0129] In one possible implementation, the space information includes one of a Transmission Configuration Indicator (TCI) state, a Quasi-Collocation (QCL), and a space relationship.
