[0047] Before the embodiments of the present application are described, the following briefly introduces the flexible duplex (flexible duplex) in the related art:

[0048] When deploying a conventional cellular network, based on the available spectrum and service characteristics, etc., a duplex mode of frequency division duplex (FDD) or time division duplex (TDD) can be used. When FDD is used, uplink transmission and downlink transmission are located at different frequency points, and they do not interfere with each other, and can be performed simultaneously. When TDD is used, uplink transmission and downlink transmission are located at the same frequency point, and are staggered by time division. The above two duplex modes have advantages and disadvantages.

[0049] In order to more flexibly use limited spectrum resources, to dynamically match service requirements, to improve resource utilization efficiency, and to improve the performance of uplink coverage, time delay, etc. of data transmission, a flexible duplex mode is proposed. A flexible duplex mode based on frequency domain non-overlapping sub-band, i.e. non-overlapping sub-band full duplex (SBFD) (which can be simply referred to as sub-band full duplex) is as follows:

[0050] 1. Network side full duplex

[0051] From the network side perspective, at the same time, uplink transmission and downlink transmission can be carried out simultaneously in different frequency domain subbands. In order to avoid interference between uplink and downlink, a certain guard band can be left between the frequency domain subbands corresponding to different transmission directions (for example, uplink subband and downlink subband).

[0052] 2. Terminal side half duplex or full duplex

[0053] When the terminal side supports half duplex, at the same time, only uplink transmission or downlink transmission can be carried out, and both cannot be carried out simultaneously. It can be understood that in this case, the uplink transmission and downlink transmission of the network side at the same time can only be for different terminals.

[0054] When the terminal side supports full duplex, similar to the network side, at the same time, uplink transmission and downlink transmission can be carried out simultaneously in different frequency domain subbands.

[0055] Figure 2 A schematic diagram of the above flexible duplex mode is given. The network side divides the frequency domain of a single carrier into three subbands in a part of downlink symbols, wherein the two sides of the carrier are downlink subbands, and the center is an uplink subband, so as to reduce the interference caused to adjacent carriers. In the third time slot, UE1 and UE2 carry out uplink transmission and downlink reception, respectively.

[0056] In Figure 2Under the scenario of the flexible duplex mode shown, a time domain unit can correspond to or distinguish multiple time domain types, such as SBFD symbols and non-SBFD symbols. For a serving cell or bandwidth part (BWP) that enables SBFD, at the network side, the settings of antennas or RFs corresponding to SBFD symbols and non-SBFD symbols can be different, to provide self-interference suppression and other capabilities for SBFD operation. Accordingly, the spatial correlation or transmission configuration indication (TCI) state corresponding to an uplink channel or signal in an SBFD symbol can also be different from that in a non-SBFD symbol. For the determination of the spatial correlation or TCI state corresponding to each channel or signal, a general idea of separate configuration has been initially formed in the study item (SI) stage, but there is a lack of research and discussion on operation details and signaling design, which leads to the terminal not knowing how to perform uplink transmission.

[0057] In view of this, the embodiments of the present application provide an uplink transmission method, an uplink transmission device, and a communication device to solve the problem of how the terminal performs uplink transmission under the flexible duplex mode.

[0058] To facilitate the description of the schemes below, the following concepts and explanations are given first:

[0059] Based on the TDD pattern configuration information provided by the network side to the UE (for example, tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated provided for a certain serving cell of the UE), the following symbol types can be distinguished: downlink symbols (DL symbols), uplink symbols (UL symbols), and flexible symbols (Flexible symbols).

[0060] When tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated is not provided for a certain Serving cell, each symbol can be considered as Flexible symbol, or follow the rules or operations corresponding to Flexible symbol.

[0061] Based on the above TDD pattern configuration information, and the SBFD configuration information provided by the network side to the UE, the following Symbol types can be further distinguished:

[0062] 1、SBFD symbol

[0063] The network side can configure some symbols as symbols that can perform SBFD operation through SBFD configuration information, that is, configure these symbols as SBFD symbols. For example, some or all symbols in a single period determined based on the TDD pattern are configured as SBFD symbols. These symbols configured as SBFD symbols can be some or all types of Symbol types distinguished based on the TDD pattern configuration information.

[0064] For a certain Serving cell configured or activated for the UE, the SBFD symbols on the Serving cell can be further distinguished as the following Symbol types:

[0065] (1) SBFD symbol for duplex mode 1

[0066] For Duplex mode 1, the network side supports SBFD operation based on full duplex; the UE side only supports SBFD operation based on half duplex, that is, the UE can only perform uplink transmission or downlink reception in a single SBFD symbol, and cannot simultaneously perform uplink transmission and downlink reception based on FDM (Frequency Division Multiplexing).

[0067] (2) SBFD symbol for duplex mode 2

[0068] For Duplex mode 2, network side supports full-duplex based SBFD operation; UE side can support full-duplex based SBFD operation, i.e., UE can perform FDM based uplink transmission and downlink reception simultaneously within a single SBFD symbol. Generally, UE supporting full-duplex based SBFD operation (i.e., supporting Duplex mode 2, or, supporting SBFD symbol for duplex mode 2) must also support half-duplex based SBFD operation (i.e., supporting Duplex mode 1, or, supporting SBFD symbol for duplex mode 1).

[0069] 2、non-SBFD symbol

[0070] A symbol not configured (or indicated) to perform SBFD operation can be considered as non-SBFD symbol.

[0071] In Rel-18 Duplex study item, it is generally agreed that different symbol types (e.g., SBFD symbol and non-SBFD symbol, or, SBFD symbol for duplex mode 1, SBFD symbol for duplex mode 2 and non-SBFD symbol) based on SBFD configuration information can be differentiated, and corresponding parameters of each Channel / Signal can be respectively (or directly) configured or (implicitly based on frequency domain offset, respective starting reference point, etc.) derived to consider / compensate for different symbol types corresponding to antenna and RF configuration (including antenna location, antenna number, connection relationship between antenna and RF chain, etc.), interference situation and limitation (including self-interference (SI), cross link interference (CLI) and corresponding limitations), etc. Accordingly, the spatial relation / TCI state (in the case of joint mode, TCI state can also be applied to uplink Channel / Signal) corresponding to uplink Channel / Signal within SBFD symbol can also be different from non-SBFD symbol.

[0072] The uplink transmission method provided by the embodiments of the present application is described in detail below in combination with some embodiments and application scenarios thereof.

[0073] Figure 3 A flowchart of an uplink transmission method provided by the embodiments of the present application is shown. As shown in Figure 3 The uplink transmission method comprises the following steps:

[0074] Step 301: The terminal determines the spatial domain transmission parameter corresponding to the first uplink transmission based on the first time domain type corresponding to the first uplink transmission.

[0075] Step 302: The terminal transmits the first uplink transmission according to the spatial domain transmission parameter corresponding to the first uplink transmission.

[0076] The first uplink transmission can comprise at least one of a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH) and a sounding reference signal (SRS).

[0077] The spatial domain transmission parameter can comprise at least one of spatial correlation information (i.e., Spatial relation) and a TCI state (i.e., TCI state).

[0078] The time domain type can be understood as the type of time domain unit. The time domain type may, for example, comprise two types of SBFD time domain unit and non-SBFD time domain unit, wherein the SBFD time domain unit can further comprise two types of SBFD time domain unit for duplex mode 1 and SBFD time domain unit for duplex mode 2. The time domain unit can be a slot (Slot), a symbol (Symbol) or the like. In the present application, the time domain unit is described by taking the symbol as an example, at this time, the time domain type can be referred to as Symbol type, which may, for example, comprise two types of SBFD symbol and non-SBFD symbol, wherein the SBFD symbol can further comprise two types of SBFD symbol for duplex mode 1 and SBFD symbol for duplex mode 2. When the time domain unit is Slot, the time domain type can be referred to as Slot type, which is not limited in the present application.

[0079] Embodiments of the present application can be applied to a Serving cell / BWP enabled with SBFD. For a Serving cell / BWP enabled with SBFD, a UE can determine a spatial relation / TCI state corresponding to an uplink channel / signal based on a symbol type. Here, the UE can be understood as a SBFD capable UE or a SBFD aware UE.

[0080] In the embodiments of the present application, the terminal determines a spatial domain transmission parameter corresponding to the first uplink transmission based on a first time domain type corresponding to the first uplink transmission; and the terminal transmits the first uplink transmission according to the spatial domain transmission parameter corresponding to the first uplink transmission; wherein the first uplink transmission includes at least one of PUCCH, PUSCH and SRS; and the spatial domain transmission parameter includes at least one of spatial correlation information and TCI state. In this way, when multiple time domain types are corresponding or distinguished in a time domain unit, the terminal can determine a spatial domain transmission parameter corresponding to an uplink transmission based on a time domain type corresponding to the uplink transmission, so that the terminal can implement flexible and reliable uplink transmission according to the determined spatial domain transmission parameter, thereby realizing uplink transmission of the terminal in a flexible duplexing scenario.

[0081] The following describes embodiments related to PUCCH transmission by taking the first uplink transmission including PUCCH as an example.

[0082] In some embodiments, the first uplink transmission includes the PUCCH.

[0083] The method further includes:

[0084] The terminal receives first information from a network side device, and the first information is used for configuring at least one set, and each set in the at least one set includes at least one spatial domain transmission parameter.

[0085] The terminal determines a spatial domain transmission parameter corresponding to the first uplink transmission based on a first time domain type corresponding to the first uplink transmission, including:

[0086] The terminal determines a spatial domain transmission parameter corresponding to the first uplink transmission from the at least one set based on a first time domain type corresponding to the first uplink transmission.

[0087] Optionally, the at least one set includes at least one of:

[0088] A first set, and any spatial domain transmission parameter in the first set can be used for any time domain type.

[0089] at least one second set, each spatial domain transmission parameter in the at least one second set corresponds to a time domain type determined by configuration information of the spatial domain transmission parameter;

[0090] a third set, each spatial domain transmission parameter in the third set corresponds to a time domain type determined by a position of the spatial domain transmission parameter in the third set;

[0091] at least one fourth set, all spatial domain transmission parameters in each of the fourth sets correspond to a same time domain type, and different fourth sets correspond to different time domain types.

[0092] Optionally, the configuration information of the spatial domain transmission parameter comprises at least one of the following:

[0093] an identifier of the spatial domain transmission parameter, and a time domain type corresponding to each spatial domain transmission parameter in the at least one second set is determined by a value of the identifier of the spatial domain transmission parameter;

[0094] first indication information of the spatial domain transmission parameter, the first indication information is used to indicate a time domain type, and a time domain type corresponding to each spatial domain transmission parameter in the at least one second set is a time domain type indicated by the first indication information of the spatial domain transmission parameter.

[0095] Optionally, the third set comprises one or more subsets, and each subset of the third set satisfies at least one of the following:

[0096] each subset of the third set is sorted according to a predetermined order, and the predetermined order represents an order of the time domain types;

[0097] a number of spatial domain transmission parameters included in each subset of the third set is allocated in a predefined manner, or directly configured or indicated.

[0098] For example, the number of spatial domain transmission parameters included in each subset of the third set can be semi-statically configured through high-layer signaling, or can be dynamically indicated by downlink control information (DCI) or medium access control (MAC) control element (CE) signaling.

[0099] For ease of understanding, the embodiments of the present application take the first information used for configuring PUCCH Spatial Relation Info as an example to exemplarily describe the configuration modes of various PUCCH Spatial Relation Info.

[0100] PUCCH Spatial Relation Info configuration mode 1: no distinction between Symbol types, and a unified configured Spatial Relation Info set (i.e., the first set) is applied.

[0101] PUCCH Spatial Relation Info configuration mode 1 can be understood as follows: for any PUCCH transmission (also referred to as PUCCH sending) corresponding to a Symbol type, or for any PUCCH transmission within a Symbol corresponding to a Symbol type, any Spatial Relation Info in the configured Spatial Relation Info set can be applied as needed; or, any Spatial Relation Info in the configured Spatial Relation Info set is not limited to the Symbol type corresponding to the PUCCH transmission to which it is applied. Here, the unified configured Spatial Relation Info set can be determined based on spatialRelationInfoToAddModList and spatialRelationInfoToReleaseList in PUCCH-Config.

[0102] PUCCH Spatial Relation Info configuration mode 2: distinguish between Symbol types and apply respective configured Spatial Relation Info sets.

[0103] In determining the configured Spatial Relation Info set corresponding to a Symbol type, any of PUCCH Spatial Relation Info configuration mode 2-1 to PUCCH Spatial Relation Info configuration mode 2-3 can be used:

[0104] PUCCH Spatial Relation Info configuration mode 2-1: distinguish between the Symbol types corresponding to each Spatial Relation Info in the configuration information of the Spatial Relation Info.

[0105] At this time, the Spatial Relation Info corresponding to each Symbol type can still be placed in a unified configuration Spatial Relation Info set (i.e., the second set). For a certain Symbol type, the Spatial Relation Info corresponding to the Symbol type can be filtered out from the configuration Spatial Relation Info set as the configuration Spatial Relation Info set corresponding to the Symbol type.

[0106] Specifically, any one of the following modes 1 and 2 can be adopted:

[0107] Mode 1: Determine the Symbol type corresponding to each Spatial Relation Info based on the PUCCH-SpatialRelationInfoId value range in which the PUCCH-SpatialRelationInfoId of the Spatial Relation Info is located. Here, it is assumed that each Symbol type corresponds to an independent PUCCH-SpatialRelationInfoId value range (which can be specified by the protocol or configured by high-layer signaling); the PUCCH-SpatialRelationInfoId value ranges corresponding to different Symbol types do not intersect with each other. When configuring the Spatial Relation Info corresponding to a certain Symbol type, the PUCCH-SpatialRelationInfoId of the Spatial Relation Info is required to be located in the PUCCH-SpatialRelationInfoId value range corresponding to the Symbol type.

[0108] Mode 2: Introduce a new parameter (i.e., the first indication information) in the configuration information of each Spatial Relation Info to indicate the Symbol type corresponding to the Spatial Relation Info.

[0109] PUCCH Spatial Relation Info configuration mode 2-2: Determine the Symbol type corresponding to a certain Spatial Relation Info based on the position of the Spatial Relation Info in the unified configuration Spatial Relation Info set.

[0110] Here it is assumed that the Spatial Relation Info corresponding to each Symbol type is placed in a unified configured Spatial Relation Info set (i.e. the third set), and the unified configured Spatial Relation Info set is an ordered set, determined based on spatialRelationInfoToAddModList and spatialRelationInfoToReleaseList in PUCCH-Config.For example, the first configured spatialRelationInfoToAddModList is taken as the initial set of the unified configured Spatial Relation Info set; the newly added Spatial Relation Info in the later configured spatialRelationInfoToAddModList is sequentially added to the tail of the unified configured Spatial Relation Info set according to the order of appearance in the spatialRelationInfoToAddModList; the modified Spatial Relation Info can either overwrite the corresponding Spatial Relation Info in the unified configured Spatial Relation Info set or be sequentially added to the tail of the unified configured Spatial Relation Info set according to the order of appearance in the spatialRelationInfoToAddModList (in this case, the corresponding Spatial Relation Info in the unified configured Spatial Relation Info set needs to be deleted); the modified Spatial Relation Info can be placed before or after the newly added Spatial Relation Info, or the modified Spatial Relation Info and the newly added Spatial Relation Info can be sequentially added to the tail of the unified configured Spatial Relation Info set according to the order of appearance in the spatialRelationInfoToAddModList (in this case, the newly added Spatial Relation Info and the modified Spatial Relation Info added to the tail of the unified configured Spatial Relation Info set can be intermingled or alternated); and the corresponding Spatial Relation Info is deleted from the unified configured Spatial Relation Info set based on the configured spatialRelationInfoToReleaseList.

[0111] Further, determine the position region of Spatial Relation Info corresponding to a certain Symbol type in the above ordered set; the configured Spatial Relation Info set corresponding to the Symbol type is composed of all Spatial Relation Info in the position region. For example, the first N1 Spatial Relation Info in the ordered set corresponds to Symbol type 1 (e.g. non-SBFD symbol) and the remaining N2 Spatial Relation Info corresponds to Symbol type 2 (e.g. SBFD symbol) according to the protocol or higher layer signaling. When determining N1 and N2, assuming that the ordered set contains N Spatial Relation Info, any of the following methods can be used:

[0112] Agree N1 = floor(N / 2) (i.e. lower integral) or N1 = ceiling(N / 2) (i.e. upper integral) and N2 = N-N1, i.e. divide the Spatial Relation Info in the ordered set into two parts or approximately into two parts, and the two parts obtained correspond to two Symbol types respectively;

[0113] Configure or indicate N1 and N2 = N-N1.

[0114] PUCCH Spatial Relation Info configuration method 2-3: respectively configure and / or maintain the configured Spatial Relation Info set (i.e. the fourth set) corresponding to each Symbol type.

[0115] When the configuration parameters corresponding to each Symbol type are provided / determined based on a single / shared PUCCH-Config, the corresponding spatialRelationInfoToAddModList or spatialRelationInfoToReleaseList can be set for each Symbol type in the PUCCH-Config; based on the spatialRelationInfoToAddModList and spatialRelationInfoToReleaseList corresponding to a certain Symbol type, the configuration Spatial Relation Info set corresponding to the Symbol type is maintained. For example, a new spatialRelationInfoToAddModList or spatialRelationInfoToReleaseList is introduced in the PUCCH-Config for the SBFD symbol, and the spatialRelationInfoToAddModList and spatialRelationInfoToReleaseList in the related art are used to maintain the configuration Spatial Relation Info set corresponding to the non-SBFD symbol.

[0116] When the configuration parameters corresponding to each Symbol type are provided / determined based on their respective PUCCH-Configs, the configuration SpatialRelation Info set corresponding to a Symbol type can be maintained based on spatialRelationInfoToAddModList and spatialRelationInfoToReleaseList in the PUCCH-Config corresponding to the Symbol type.

[0117] The above provides exemplary descriptions of various PUCCH Spatial Relation Info configuration methods. Through the above PUCCH Spatial Relation Info configuration methods, the terminal can determine the Spatial Relation Info corresponding to the PUCCH from the configured Spatial Relation Info set based on the first time domain type corresponding to the PUCCH, so that the terminal can transmit the PUCCH according to the Spatial Relation Info corresponding to the PUCCH.

[0118] In some embodiments, the method further comprises:

[0119] The terminal receives second information from the network side device, and the second information is used to indicate the active spatial domain transmission parameter corresponding to the resource of the first uplink transmission.

[0120] The terminal determines the spatial domain transmission parameter corresponding to the first uplink transmission based on the first time domain type corresponding to the first uplink transmission, including:

[0121] The terminal determines the spatial domain transmission parameter corresponding to the first uplink transmission from the active spatial domain transmission parameter corresponding to the resource of the first uplink transmission based on the first time domain type corresponding to the first uplink transmission.

[0122] Optionally, the second information is used to indicate at least one of the following:

[0123] The active spatial domain transmission parameter corresponding to all uplink transmission occasions corresponding to the resource of the first uplink transmission.

[0124] Among the N time domain types corresponding to the resource of the first uplink transmission, the active spatial domain transmission parameter corresponding to each uplink transmission occasion corresponding to each time domain type, N is an integer greater than or equal to 1.

[0125] In this embodiment, the active spatial domain transmission parameter corresponding to each occasion among all occasions corresponding to a certain PUCCH resource is indicated by the second information, so that when the corresponding PUCCH transmission is initiated based on a certain occasion, the terminal can use the active spatial domain transmission parameter corresponding to the occasion to perform PUCCH transmission. It should be noted that not every occasion will have corresponding PUCCH transmission.

[0126] Optionally, among the N time domain types corresponding to the resource of the first uplink transmission, the active spatial domain transmission parameter corresponding to each uplink transmission occasion corresponding to each time domain type is indicated by the same MAC CE; or,

[0127] Among the N time domain types corresponding to the resource of the first uplink transmission, the active spatial domain transmission parameter corresponding to each uplink transmission occasion corresponding to each time domain type is indicated by different MAC CEs.

[0128] Here, the active spatial domain transmission parameter corresponding to each uplink transmission occasion corresponding to each time domain type is indicated by different MAC CEs, which can be understood as using independent MAC CEs to indicate the active spatial domain transmission parameter corresponding to each uplink transmission occasion corresponding to each time domain type.

[0129] Optionally, in the case that the N time domain types corresponding to the resources of the first uplink transmission are indicated by the same MAC CE, and each of the uplink transmission occasions corresponding to each of the time domain types corresponds to an activated spatial domain transmission parameter, the MAC CE comprises at least one of the following:

[0130] N first indication fields, the N first indication fields being used for respectively indicating the activated spatial domain transmission parameter corresponding to each of the N time domain types;

[0131] a second indication field, the second indication field being used for jointly indicating the activated spatial domain transmission parameter corresponding to each of the N time domain types.

[0132] Optionally, in the case that the N time domain types corresponding to the resources of the first uplink transmission are indicated by different MAC CEs, and each of the uplink transmission occasions corresponding to each of the time domain types corresponds to an activated spatial domain transmission parameter, the MAC CE comprises at least one of the following:

[0133] a third indication field, the third indication field being used for indicating the time domain type corresponding to the MAC CE;

[0134] a fourth indication field, the fourth indication field being used for indicating the activated spatial domain transmission parameter corresponding to the corresponding time domain type;

[0135] a fifth indication field, the fifth indication field being used for indicating an activation state or a deactivation state of the spatial domain transmission parameter corresponding to the corresponding time domain type.

[0136] For the convenience of understanding, the embodiments of the present application take the activation of a certain PUCCH resource corresponding to SpatialRelation Info as an example to exemplarily describe various PUCCH Spatial Relation Info activation modes.

[0137] PUCCH Spatial Relation Info activation mode 1: without distinguishing Symbol type, indicating that all Occasions of the PUCCH resource uniformly use / cross Symbol type to share the use of the activated Spatial Relation Info.

[0138] The PUCCH Spatial Relation Info activation mode 1 corresponds to the PUCCH Spatial Relation Info configuration mode 1.

[0139] The network-side device can use a MAC CE irrelevant to (or not considering the impact of) the Symbol type to indicate the activation / deactivation state of each SpatialRelation Info in a unified configuration Spatial Relation Info set for the PUCCH resource, and indicate a single activated Spatial Relation Info from the set as the SpatialRelation Info uniformly used by all Occasions of the PUCCH resource or shared and used across Symbol types.

[0140] The MAC CE here can be understood as a PUCCH spatial relation Activation / Deactivation MAC CE, or a MAC CE with the same or similar function.

[0141] For PUCCH Spatial Relation Info activation mode 1, the existing format of the PUCCH spatial relation Activation / Deactivation MAC CE can be followed. Based on the single activated Spatial Relation Info indicated by the MAC CE for the PUCCH resource, the PUCCH transmission in the Occasion corresponding to any Symbol type can be applied, or in other words, the Symbol type corresponding to the Occasion in which the PUCCH resource applies the indicated activated Spatial Relation Info for PUCCH transmission is not limited.

[0142] PUCCH Spatial Relation Info activation mode 2: respectively indicate the respective activated Spatial Relation Info for the Occasion corresponding to different Symbol types for the PUCCH resource.

[0143] Generally, PUCCH Spatial Relation Info activation mode 2 corresponds to PUCCH Spatial Relation Info configuration mode 2. Alternatively, PUCCH Spatial Relation Info activation mode 2 can also correspond to PUCCH Spatial Relation Info configuration mode 1.

[0144] In the case of using the MAC CE to indicate the activated Spatial Relation Info corresponding to each Symbol type to indicate the SpatialRelation Info applied by the PUCCH resource to the PUCCH transmission in the Occasion corresponding to each Symbol type, either of the PUCCH Spatial Relation Info activation mode 2-1 and the PUCCH Spatial Relation Info activation mode 2-2 can be adopted:

[0145] The PUCCH Spatial Relation Info activation mode 2-1 uses the same MAC CE to indicate the activated Spatial Relation Info corresponding to each (or at least one) Symbol type.

[0146] The PUCCH Spatial Relation Info activation mode 2-1 can be understood as a single MAC CE being used to indicate the activated Spatial Relation Info corresponding to more than one Symbol type.

[0147] Specifically, the existing format definition or indication limit of the PUCCH spatial relation Activation / Deactivation MAC CE can be adjusted, or a new MAC CE is introduced, and either of the PUCCH Spatial Relation Info activation mode 2-1-1 and the PUCCH Spatial Relation Info activation mode 2-1-2 is adopted:

[0148] The PUCCH Spatial Relation Info activation mode 2-1-1 distinguishes the Symbol type in the MAC CE and sets the Spatial Relation Info indication field (i.e., the first indication field) corresponding to each Symbol type respectively.

[0149] The Spatial Relation Info indication fields corresponding to each Symbol type can be arranged in sequence in the MAC CE based on the order of Symbol types. The order of Symbol types can be specified by the protocol or configured by higher layer signaling. For example, it is specified by the protocol that the Spatial Relation Info indication field corresponding to non-SBFD symbol appears first in a certain MAC CE, and then the Spatial Relation Info indication field corresponding to SBFD symbol appears after it.

[0150] Wherein, the Spatial Relation Info indication field corresponding to a certain Symbol type is used to indicate one of the following:

[0151] Indicate the activated Spatial Relation Info corresponding to a certain Symbol type as the Spatial Relation Info used by the PUCCH resource and the Occasion corresponding to the Symbol type.

[0152] Indicate the activation / deactivation state of each Spatial Relation Info corresponding to the Symbol type, to indicate a single activated Spatial Relation Info from the configured Spatial Relation Info set corresponding to the Symbol type, as the Spatial Relation Info used by the PUCCH resource and the Occasion corresponding to the Symbol type.

[0153] When referring to a certain Spatial Relation Info (to indicate whether it is the activated Spatial Relation Info corresponding to a certain Symbol type), it can be based on any of (1) and (2):

[0154] (1) PUCCH-SpatialRelationInfoId. When PUCCH Spatial Relation Info configuration mode 2 is adopted, and the Spatial Relation Info corresponding to PUCCH-SpatialRelationInfoId is indicated as activated, the network side needs to ensure that the activated Spatial Relation Info is located in the configured Spatial Relation Info set corresponding to the Symbol type.

[0155] (2) The position in the configured Spatial Relation Info set. Here, "the position in the configured Spatial Relation Info set" can be understood as the sequence number or subscript of the referenced Spatial Relation Info in the unified configured Spatial Relation Info set (when applied to PUCCH Spatial Relation Info configuration mode 1) or the sequence number or subscript of the Spatial Relation Info in the configured Spatial Relation Info set corresponding to the Symbol type (when applied to PUCCH Spatial Relation Info configuration mode 2) (it is required that the Spatial Relation Info set in these cases be maintained in the form of an ordered set).

[0156] PUCCH Spatial Relation Info activation mode 2-1-1 can be applied to PUCCH Spatial Relation Info configuration mode 1, PUCCH Spatial Relation Info configuration mode 2-1, PUCCH Spatial Relation Info configuration mode 2-2, and PUCCH Spatial Relation Info configuration mode 2-3.

[0157] PUCCH Spatial Relation Info activation mode 2-1-2: simultaneously indicate the activated Spatial Relation Info corresponding to each Symbol type in the MAC CE using the same Spatial Relation Info indication field (i.e., the second indication field).

[0158] For example (assuming example 1), the activated / deactivated state of each Spatial Relation Info in the unified configured Spatial Relation Info set can be indicated based on the PUCCH-SpatialRelationInfoId or the position in the configured Spatial Relation Info set, and N (assuming that the number of Symbol types corresponding to the activated Spatial Relation Info needs to be indicated is N) activated Spatial Relation Infos are indicated from the set to be applied to each Symbol type, respectively.

[0159] For example, assuming example 2, a single PUCCH-SpatialRelationlnfoId or a single location in the configured Spatial Relation Info set can be indicated by the Spatial Relation Info indication field in the MAC CE. Optionally, based on the indicated single ID or single location, and a predefined rule, N IDs or N locations are determined. For example, if the first ID / location is indicated in the MAC CE, then the determined N IDs / locations are: the first ID / location+i, i=0,…,N-1; or if the last ID / location is indicated in the MAC CE, then the determined N IDs / locations are: the last ID / location-i, i=0,…,N-1. Optionally, a modulo operation can be further introduced to avoid ID / location overflow. For example, each of the determined N IDs / locations is further subjected to a modulo operation with respect to (max ID+1) / total number of locations to obtain the final N IDs / locations (assuming each ID / location is numbered from 0).

[0160] PUCCH Spatial Relation Info activation mode 2-1-2 can be applied to PUCCH Spatial Relation Info configuration mode 1, PUCCH Spatial Relation Info configuration mode 2-1, PUCCH Spatial Relation Info configuration mode 2-2, and PUCCH Spatial Relation Info configuration mode 2-3.

[0161] When applied to PUCCH Spatial Relation Info configuration manner 1, a predefined rule can be introduced to determine the Symbol type corresponding to the N activated Spatial Relation Infos (for example, the N activated Spatial Relation Infos in example 1, or the N Spatial Relation Infos determined from the unified configuration Spatial Relation Info set based on the N IDs / positions determined in example 2). The predefined rule can be: the N activated Spatial Relation Infos are in ascending or descending order based on PUCCH-SpatialRelationInfoId or the positions in the configuration Spatial Relation Info set, and are one by one corresponding to the N Symbol types based on the order of the Symbol types (see the corresponding description in the foregoing). For example, in the 2 activated Spatial Relation Infos, the activated Spatial Relation Info with the smaller PUCCH-SpatialRelationInfoId corresponds to the non-SBFD symbol, and the activated Spatial Relation Info with the larger PUCCH-SpatialRelationInfoId corresponds to the SBFD symbol.

[0162] When applied to PUCCH Spatial Relation Info configuration manner 2-1, based on the configuration information of each Spatial Relation Info indicated as an activated state (based on example 1, or indicated in the manner of determining N IDs / positions in example 2), the Symbol type corresponding to each activated Spatial Relation Info can be known.

[0163] When applied to PUCCH Spatial Relation Info configuration manner 2-2, based on the position of each Spatial Relation Info indicated as an activated state in the unified configuration Spatial Relation Info set (based on example 1, or indicated in the manner of determining N IDs / positions in example 2), the Symbol type corresponding to each activated Spatial Relation Info can be known.

[0164] When applied to PUCCH Spatial Relation Info configuration mode 2-3, the activated Spatial Relation Info corresponding to each Symbol type can be determined based on Example 2:

[0165] When only a single ID is indicated in Example 2, it only applies to the case where the ID space of Spatial Relation Info corresponding to different Symbol types is allowed to overlap (i.e. the ID of Spatial Relation Info in the configured Spatial Relation Info set corresponding to each Symbol type only requires not to be repeated in the configured Spatial Relation Info set corresponding to the same Symbol type (i.e. the ID is required to be unique within a single Symbol type), and is allowed to be repeated in the configured Spatial Relation Info set corresponding to different Symbol types (i.e. the ID space corresponding to different Symbol types is allowed to overlap)), and at this time, based on the indicated single ID, a single Spatial Relation Info corresponding to this single ID is determined in the configured Spatial Relation Info set corresponding to each Symbol type respectively, as the activated Spatial Relation Info corresponding to each Symbol type respectively.

[0166] When only a single location is indicated in Example 2, based on the indicated single location, a single Spatial Relation Info corresponding to this single location is determined in the configured Spatial Relation Info set corresponding to each Symbol type respectively, as the activated Spatial Relation Info corresponding to each Symbol type respectively.

[0167] When N IDs / locations are determined in Example 2, the N IDs / locations can be corresponded to the N Symbol types one by one based on ascending order or descending order and based on the order of Symbol types (see the corresponding description in the foregoing), and then based on the ID / location corresponding to each Symbol type respectively, a single Spatial Relation Info corresponding to the ID / location is determined in the configured Spatial Relation Info set corresponding to each Symbol type respectively, as the activated Spatial Relation Info corresponding to each Symbol type respectively.

[0168] PUCCH Spatial Relation Info activation mode 2-2: use independent MAC CE to indicate the activated Spatial Relation Info corresponding to each (or certain) Symbol type.

[0169] PUCCH Spatial Relation Info activation mode 2-2 can be understood as a single MAC CE is only used to indicate the activated Spatial Relation Info corresponding to a single Symbol type, and the MAC CE contains information / fields for indicating the Symbol type.

[0170] Among the MAC CE corresponding to a certain Symbol type, the Spatial Relation Info indication field is used to indicate one of the following:

[0171] Indicate the activated Spatial Relation Info corresponding to the Symbol type (at this time, the Spatial Relation Info indication field is the fourth indication field), which is the Spatial Relation Info used by the Occasion corresponding to the PUCCH resource and the Symbol type;

[0172] Indicate the activation / deactivation state of each Spatial Relation Info corresponding to the Symbol type (at this time, the Spatial Relation Info indication field is the fifth indication field), so as to indicate a single activated Spatial Relation Info from the configured Spatial Relation Info set corresponding to the Symbol type, which is the Spatial Relation Info used by the Occasion corresponding to the PUCCH resource and the Symbol type.

[0173] When referring to a certain Spatial Relation Info (to indicate whether it is the activated Spatial Relation Info corresponding to the Symbol type), based on any one of (3) and (4):

[0174] (3) PUCCH-SpatialRelationInfoId. When PUCCH Spatial Relation Info configuration mode 2 is adopted, and the Spatial Relation Info corresponding to PUCCH-SpatialRelationInfoId is indicated as the active state, it is necessary to ensure by the network side that the active Spatial Relation Info is located in the configuration Spatial Relation Info set corresponding to the Symbol type.

[0175] (4) The location in the configuration Spatial Relation Info set. Here, "the location in the configuration Spatial Relation Info set" can be understood as the sequence number or subscript of the referenced Spatial Relation Info in the unified configuration Spatial Relation Info set (when applied to PUCCH Spatial Relation Info configuration mode 1) or the sequence number or subscript of the Spatial Relation Info in the configuration Spatial Relation Info set corresponding to the Symbol type (when applied to PUCCH Spatial Relation Info configuration mode 2) (it is required that the Spatial Relation Info set in these cases be maintained in the form of an ordered set).

[0176] PUCCH Spatial Relation Info activation mode 2-2 can be applied to PUCCH Spatial Relation Info configuration mode 1, PUCCH Spatial Relation Info configuration mode 2-1, PUCCH Spatial Relation Info configuration mode 2-2, and PUCCH Spatial Relation Info configuration mode 2-3.

[0177] Generally, when PUCCH Spatial Relation Info configuration manner 2 is adopted, for any Symbol type (e.g., Semi-static DL symbol configured as SBFD symbol, Semi-static flexible symbol configured as SBFD symbol, Semi-static UL symbol, etc.) corresponding to the Symbol(s) where PUCCH transmission can exist / occur, the corresponding configured Spatial Relation Info set is configured / determined. Optionally, the corresponding configured Spatial Relation Info set is configured / determined only for certain Symbol type(s), or is not configured / determined for certain Symbol type(s).

[0178] When no configured Spatial Relation Info set is configured / determined for PUCCH transmission (assume Case 1; can be understood as PUCCH Spatial Relation Info configuration manner 1 is adopted), or no configured Spatial Relation Info set is configured / determined for certain Symbol type (assume given Symbol type) corresponding to the Symbol(s) where PUCCH transmission exists / occurs (assume Case 2; can be understood as PUCCH Spatial Relation Info configuration manner 2 is adopted), for the Spatial relation / TCI state of PUCCH transmission (for Case 1), or for the Spatial relation / TCI state of PUCCH transmission within the Symbol corresponding to the given Symbol type (for Case 2), it can be one of the following:

[0179] When the network side does not configure the reference signal for UE to estimate the path loss (for example, no pathlossReferenceRSs parameter is provided), or before the network side provides the UE with dedicated configuration parameters, the UE can determine the Spatial relation / TCI state of the PUCCH transmission based on the SSB index used when the UE measures / reads the Synchronization Signal Block (SSB), that is, using the Spatial relation / TCI state corresponding to the SSB index as the Spatial relation / TCI state of the PUCCH transmission. When the SSB can be transmitted in the Symbol corresponding to each (or more than one) Symbol type, if there may be differences in transmission attributes between the SSBs transmitted in the Symbols corresponding to different Symbol types, for Case 1, when determining the Spatial relation / TCI state of the PUCCH transmission, the Symbol type corresponding to the reference SSB can be specified by the protocol or configured by the high layer signaling, for example, the protocol specifies to refer to the SSB corresponding to the non-SBFD symbol; for Case 2, when determining the Spatial relation / TCI state of the PUCCH transmission in the Symbol corresponding to a given Symbol type, the Symbol type corresponding to the reference SSB can be specified by the protocol or configured by the high layer signaling, for example, the protocol specifies to refer to the SSB corresponding to the given Symbol type (that is, the SSB and the Symbol type corresponding to the PUCCH transmission are the same).

[0180] When the network side configures the UE with reference signals for estimating path loss (e.g., provides the pathlossReferenceRSs parameter), the UE can determine the Spatialrelation / TCI state of the PUCCH transmission based on a predefined downlink reference signal for estimating path loss, i.e., use the Spatial relation / TCI state corresponding to the downlink reference signal for estimating path loss as the Spatial relation / TCI state of the PUCCH transmission; for example, the predefined downlink reference signal for estimating path loss is the referenceSignal corresponding to the pucch-PathlossReferenceRS-Id index 0. For Case 2, the network side can distinguish the Symbol type and configure the UE with reference signals for estimating path loss respectively, at this time, when determining the Spatial relation / TCI state of the PUCCH transmission, the predefined downlink reference signal for estimating path loss used corresponds to the given Symbol type.

[0181] The above describes the embodiments related to PUCCH transmission. The following describes the embodiments related to PUSCH transmission, taking the first uplink transmission including PUSCH as an example.

[0182] In some embodiments, the first uplink transmission includes PUSCH;

[0183] The method further includes:

[0184] The terminal determines the first time domain type;

[0185] The terminal determines the spatial domain transmission parameter corresponding to the first uplink transmission based on the first time domain type corresponding to the first uplink transmission, including:

[0186] The terminal determines the spatial domain transmission parameter corresponding to the first uplink transmission based on the SRS resource corresponding to the first time domain type.

[0187] PUSCH transmission (also referred to as PUSCH sending) includes codebook based PUSCH transmission and non-codebook based PUSCH transmission.

[0188] When it is needed to differentiate the time domain type to determine the uplink transmission properties (including Spatial relation, power control, etc. properties), for the configuration of SRS resource for Codebook based PUSCH transmission (usage parameter of SRS resource set is configured as 'codebook') or Non-Codebook based PUSCH transmission (usage parameter of SRS resource set is configured as 'nonCodebook'), either of the following ways can be adopted:

[0189] configuring corresponding SRS resource set for different Symbol type respectively within the same SRS-Config;

[0190] configuring corresponding SRS-Config for different Symbol type respectively (at this time, a single SRS-Config only contains SRS resource set corresponding to the Symbol type corresponding to this SRS-Config).

[0191] It can be understood that in the above case, PUSCH transmission also needs to differentiate Symbol type, at this time, the Symbol type corresponding to the PUSCH transmission and the SRS resource it refers to are the same.

[0192] Here, the "referenced SRS resource" can be understood as the SRS resource that the UE refers to when determining the set of antenna ports and the transmission beam corresponding to the PUSCH transmission. For Codebook-based PUSCH transmission, the UE uses the same antenna ports as the SRS ports in the SRS resource to transmit the PUSCH; for Non-Codebook-based PUSCH transmission, the UE performs one-to-one mapping from the indicated SRS resource indicator (SRI) (corresponding to one or more single-port SRS resources) to the indicated dedicated demodulation reference signal (DM-RS) port and its corresponding PUSCH layer {0...v-1}, and the UE uses the same antenna ports as the SRS ports in the SRS resource indicated by the SRI to transmit the PUSCH. The "referenced SRS resource" can be indicated in the uplink scheduling downlink control information (DCI) (for example, indicated by the SRI field in the DCI format 0_1) or indicated by the high-layer configuration parameter of the Type-1 configured grant (CG) (for example, indicated by the parameter ConfiguredGrantConfig->rrc-ConfiguredUplinkGrant->srs-ResourceIndicator; here, "->" is used to represent a certain field in the previous message or field, for example, ConfiguredGrantConfig->rrc-ConfiguredUplinkGrant->srs-ResourceIndicator represents the srs-ResourceIndicator parameter in the rrc-ConfiguredUplinkGrant sub-field of the ConfiguredGrantConfig field, and similar expressions throughout the text follow the interpretation here).

[0193] Optionally, the terminal determines the first time domain type, including at least one of the following:

[0194] The terminal determines the first time domain type based on third information from the network side device, and the third information is used for scheduling the first uplink transmission.

[0195] The terminal determines a first time domain type corresponding to the first uplink transmission based on a time domain position where the first uplink transmission is located.

[0196] The third information can be understood as uplink scheduling DCI.

[0197] For a Serving cell / BWP enabled with SBFD, the network side can indicate the Symbol type corresponding to the PUSCH through the uplink scheduling DCI. It should be noted that the network side can also indicate the Symbol type corresponding to the SRS through the uplink scheduling DCI, or the network side can indicate the Symbol type corresponding to the PUSCH and the SRS through the uplink scheduling DCI (as known from the foregoing description, the Symbol types corresponding to the two are the same, so the same indication can be used); to avoid repetition, this will not be described in detail.

[0198] Optionally, the terminal determines the first time domain type based on third information from the network side device, including at least one of the following:

[0199] The third information includes a sixth indication field, the sixth indication field being used to indicate the time domain type corresponding to the first uplink transmission, and the terminal determines the first time domain type based on the sixth indication field;

[0200] The terminal determines the first time domain type based on a time domain position of the third information.

[0201] Optionally, the time domain types corresponding to the time domain units where the transmission occasions of the first uplink transmission are located are all the first time domain type; or,

[0202] The time domain types corresponding to the time domain units where the transmission occasions of the first uplink transmission are located are the same time domain type.

[0203] Optionally, in a case where the time domain types corresponding to the time domain units where at least part of the transmission occasions of the first uplink transmission are located are not the first time domain type, the method further includes at least one of the following:

[0204] The terminal discards the at least part of the transmission occasions;

[0205] The terminal adjusts the time domain types corresponding to the time domain units where the at least part of the transmission occasions are located to the first time domain type;

[0206] The terminal postpones the at least part of the transmission occasions to the time domain units corresponding to the first time domain type.

[0207] Optionally, in a case where the time domain types corresponding to the time domain units where the transmission occasions of the first uplink transmission are located are more than one, the method further includes at least one of the following:

[0208] the terminal discards the transmission occasion of the first uplink transmission;

[0209] the terminal postpones the transmission occasion of the first uplink transmission until the time domain unit where the transmission occasion of the first uplink transmission is located corresponds to one time domain type;

[0210] the terminal transmits the first uplink transmission based on a target time-frequency resource in the time domain unit corresponding to a second time domain type in the time domain unit where the transmission occasion of the first uplink transmission is located, wherein the second time domain type is any one of the plurality of time domain types corresponding to the time domain unit where the transmission occasion of the first uplink transmission is located, and the target time-frequency resource is the time-frequency resource of the transmission occasion of the first uplink transmission in the time domain unit corresponding to the second time domain type.

[0211] It should be noted that the target time-frequency resource can be a time-frequency resource in a part of the time domain unit corresponding to the first uplink transmission, and therefore, transmitting the first uplink transmission based on the target time-frequency resource can be understood as a part of the uplink transmission split from the first uplink transmission.

[0212] For ease of understanding, the embodiments of the present application take PUSCH Symbol type as an example to exemplarily illustrate the determination manner of various PUSCH Symbol types.

[0213] PUSCH Symbol type determination manner 1: explicitly indicating Symbol type in uplink scheduling DCI.

[0214] A new indication field can be introduced in the corresponding DCI format, or the indication bits of the existing indication field in the DCI format can be reinterpreted to explicitly indicate the Symbol type corresponding to PUSCH / SRS. For example, 1 bit in the DCI format is used for indication, and a value of 0 represents a non-SBFD symbol and a value of 1 represents an SBFD symbol.

[0215] Optionally, the UE performs one of the following (a) and (b):

[0216] (a) The UE expects that all the scheduled PUSCHs (corresponding to each PUSCH occasion) are located in the symbols corresponding to the indicated Symbol type.

[0217] (b) When the scheduled PUSCH occupies symbols corresponding to other Symbol types in addition to the indicated Symbol type, one of the following (b.1) to (b.3) is performed:

[0218] (b.1) The UE adjusts all the symbols corresponding to the other Symbol type to the indicated Symbol type, and performs the PUSCH transmission operation, e.g., the UE performs the scheduled PUSCH transmission operation based on the existing specification. This approach can be understood as supporting dynamic (Dynamic) SBFD.

[0219] (b.2) The UE discards the PUSCH occasion occupying at least one symbol corresponding to the other Symbol type, and performs the PUSCH transmission operation for the PUSCH occasion occupying only the symbols corresponding to the indicated Symbol type. Optionally, when the number of symbols corresponding to the other Symbol type occupied by a certain PUSCH occasion is greater than or equal to XI (XI is specified by the protocol or configured by higher layer signaling), or the ratio of the symbols corresponding to the other Symbol type to the symbols (assuming the first symbol) corresponding to the indicated Symbol type occupied by the PUSCH occasion is greater than or equal to X2 (X2 is specified by the protocol or configured by higher layer signaling), the UE can use the time-frequency resources within the first symbol of the PUSCH occasion to perform the corresponding PUSCH transmission operation, without discarding.

[0220] (b.3) UE postpones the PUSCH occasion which occupies at least one symbol corresponding to other symbol type until the PUSCH occasion only occupies symbols corresponding to the indicated symbol type, at this time, UE performs the PUSCH transmission operation for the PUSCH occasion. Optionally, the next PUSCH occasion after the PUSCH occasion keeps the relative time domain position with the PUSCH occasion to determine its initial time domain position, and then performs the necessary postponement operation according to the foregoing description, and so on. Generally, such operation can be applied to the scenario where PUSCH repetition Type A is configured. Optionally, when the number of symbols occupied by a certain PUSCH occasion corresponding to other symbol type is greater than or equal to Y1 (Y1 is specified by the protocol or configured by higher layer signaling), or the proportion of symbols occupied by the PUSCH occasion corresponding to other symbol type and the symbols corresponding to the indicated symbol type (assuming the first symbol) is greater than or equal to Y2 (Y2 is specified by the protocol or configured by higher layer signaling), for the PUSCH occasion, UE uses the time-frequency resources within the second symbol where the PUSCH occasion is located to perform the corresponding PUSCH transmission operation without postponing.

[0221] PUSCH Symbol type determination method 2: determine the symbol type based on the time domain position of the scheduled PUSCH.

[0222] PUSCH Symbol type determination method 2 can be understood as: using the symbol type corresponding to the symbol where the scheduled PUSCH (corresponding to each PUSCH occasion) is located to determine the symbol type corresponding to the PUSCH, at this time, there is no need to explicitly indicate the symbol type in the uplink scheduling DCI.

[0223] Optionally, UE performs one of the following (x) and (y):

[0224] (x) UE expects that all the scheduled PUSCHs (corresponding individual PUSCH occasions) are located within the symbols corresponding to a single Symbol type. Optionally, UE expects that the single Symbol type corresponding to a single PUSCH occasion allows PUSCH transmission (i.e. the symbols corresponding to this Symbol type contain Uplink / Flexible resources, including Uplink resources within Full UL symbols, Uplink resources within UL subbands of SBFD symbols, Flexible resources within Full flexible symbols, etc.); further, UE expects that the time-frequency resources corresponding to a single PUSCH occasion are located within Uplink / Flexible resources.

[0225] (y) When a certain PUSCH occasion of the scheduled PUSCHs occupies symbols corresponding to more than one Symbol type (assume corresponding N Symbol types), perform any one of (y.1) to (y.3):

[0226] (y.1) UE drops this PUSCH occasion;

[0227] (y.2) UE postpones this PUSCH occasion (based on Slot / Symbol granularity) until the symbols occupied by this PUSCH occasion correspond to a single Symbol type; optionally, it is required that the time-frequency resources corresponding to this PUSCH occasion are located within Uplink / Flexible resources;

[0228] (y.3) The UE performs corresponding PUSCH transmission operation based on the time-frequency resources within the symbols corresponding to each of the N symbol types for the PUSCH occasion. Optionally, the UE performs corresponding PUSCH transmission operation for the time-frequency resources within the symbols corresponding to a certain symbol type for the PUSCH occasion only when the number or proportion of symbols corresponding to the symbol type is greater than or equal to Z (Z is specified by the protocol or configured by higher layer signaling). Optionally, for a single PUSCH occasion, the number of symbol types for which corresponding PUSCH transmission operation is performed is not more than N1 (N1 is specified by the protocol or configured by higher layer signaling). In actual selection, the UE can determine the symbol type sequence based on any one of (y.3.1) and (y.3.2) to select no more than N1 symbol types from the symbol type sequence:

[0229] (y.3.1) The N symbol types are arranged in descending order based on the number or proportion of symbols corresponding to each symbol type to obtain a symbol type sequence;

[0230] (y.3.2) From the N symbol types, N2 symbols whose corresponding frequency domain resources of the PUSCH occasion are located within the uplink / flexible resources are selected, and the N2 symbol types are arranged in descending order based on the number or proportion of symbols corresponding to each symbol type to obtain a symbol type sequence.

[0231] PUSCH Symbol type determination method 3: determining the symbol type based on the time domain position of the uplink scheduling DCI.

[0232] PUSCH Symbol type determination method 3 can be understood as: using the symbol type corresponding to the symbol where the uplink scheduling DCI or the control resource set (CORESET) detecting the uplink scheduling DCI is located to determine the symbol type corresponding to the PUSCH, for example, the symbol type corresponding to the symbol where the uplink scheduling DCI is located is non-SBFD symbol, then the symbol type corresponding to the PUSCH is determined as SBFD symbol. At this time, there is no need to explicitly indicate the symbol type in the uplink scheduling DCI.

[0233] After determining the Symbol type, the UE can perform the related operations in the PUSCH Symbol type determination manner 1, which will not be repeated here.

[0234] It should be noted that for the SRS resource set whose usage parameter is configured as 'nonCodebook', the base station can configure a single associated NZP CSI-RS resource for the SRS resource set. Similarly, it is required that the associated NZP CSI-RS resource and the SRS resource set correspond to the same Symbol type.

[0235] In summary, for the Serving cell / BWP enabled with SBFD, the determination of the Spatial relation / TCI state corresponding to the uplink Channel / Signal (including configuration, activation, indication, etc.), the embodiments of the present application give various feasible determination methods and the corresponding UE behavior, so as to match different SBFD deployment scenarios, to flexibly and efficiently realize the SBFD operation, and also realize the uplink transmission of the terminal in the flexible duplexing scenario.
