Description

Technical Field

[0001] This disclosure relates to a method for receiving a multi-entity downlink shared channel (multi-PDSCH) and user equipment (UE) using the same method. Prior Technology

[0002] In wireless communication systems, especially 5G systems, base stations (BSs) can use different symbol types to transmit and receive signals depending on subcarrier allocation configurations. One such configuration is called Subband-Fully-Duplex (SBFD) symbol, where the BS (e.g., gNB) can transmit and receive simultaneously in different subbands. To manage self-interference, spatial separation may be required between the BS's transmission and reception, resulting in different antenna configurations or beamforming settings for transmission and reception.

[0003] In contrast, non-SBFD symbols do not support simultaneous transmission and reception. The BS must switch between transmission and reception in a time-division manner, eliminating the need for complex interference control. Therefore, the antenna configuration of the BS during non-SBFD symbols may differ significantly from that used during SBFD symbols.

[0004] Differences in spatial configuration between SBFD and non-SBFD symbols can pose challenges for the UE, especially when the UE needs to receive multiple physical downlink shared channels (PDSCHs) across different symbol types. In particular, if the UE applies a fixed spatial reception configuration inconsistent with the BS's changing transmission mode, the UE may fail to decode downlink transmissions correctly. Summary of the Invention

[0010] The UE can schedule multiple PDSCHs from a single downlink control information (DCI) and a DCI field "Transmission Configuration Indication" (if the DCI field exists) indicating the status of a single transmission configuration indication (TCI). The network (or BS) can transmit signaling to the UE to configure timeDurationForQCL or tci-PresentInDCI to the UE. The UE can receive the DCI from the network, where the DCI can indicate the reception of multiple PDSCHs. Multiple PDSCHs can include PDSCHs associated with different symbol types (e.g., a first symbol type and a second symbol type different from the first symbol type). If the physical downlink shared channel (PDSCH) scheduling offset of all PDSCHs is greater than or equal to timeDurationForQCL, then: Case 1: If tci-PresentInDCI is enabled (e.g., if the TCI field is included in the DCI), the UE can use a single quasi-co-location (QCL) assumption based on a single DCI field "Transmission Configuration Indicator" indicator code point to receive each scheduled PDSCH, as shown in Figure 1. Figure 1 illustrates a PDSCH reception schematic 100 according to an embodiment of this disclosure, where "D" represents the downlink reception time slot. That is, the UE can use the QCL assumption indicated by the TCI field of the DCI to receive the PDSCH; Case 2: If tci-PresentInDCI is disabled (e.g., if the TCI field is not included in the DCI), the UE can use a single QCL assumption of multiple PDSCHs scheduled by a single DCI to receive each scheduled PDSCH, as shown in Figure 2, where Figure 2 illustrates a PDSCH reception schematic 200 according to an embodiment of this disclosure. In other words, the UE can use the QCL assumption of DCI reception to receive PDSCH.

[0011] The UE can receive multiple PDSCHs scheduled by a single DCI and a single DCI field "Transmission Configuration Indication" indicating the status of a single TCI (if the DCI field exists). If the PDSCH scheduling offset of any scheduled PDSCH is less than timeDurationForQCL, the UE can use the QCL assumption of the preset beam to receive any scheduled PDSCH. If the PDSCH scheduling offset of each scheduled PDSCH is greater than or equal to timeDurationForQCL, then: Case 1: If tci-PresentInDCI is enabled, the UE can use the single QCL assumption based on the single DCI field "Transmission Configuration Indication" indicator code point to receive each scheduled PDSCH; Case 2: If tci-PresentInDCI is disabled, the UE can use the single QCL assumption of multiple PDSCHs scheduled by the single DCI to receive each scheduled PDSCH.

[0012] Figure 3 illustrates a PDSCH reception schematic 300 according to an embodiment of this disclosure. Assume tci-PresentInDCI is enabled. The UE can determine whether the time offset (e.g., PDSCH scheduling offset) between the DCI and the PDSCH resource indicated by the DCI is greater than or equal to timeDurationForQCL. Since the time offset corresponding to the first PDSCH is less than timeDurationForQCL, the UE can use the QCL assumption of a preset beam to receive the first PDSCH. Since the time offset corresponding to the second PDSCH (or the third or fourth PDSCH) is greater than or equal to timeDurationForQCL, the UE can use the QCL assumption indicated by the TCI field to receive the second PDSCH (or the third or fourth PDSCH).

[0013] Figure 4 illustrates a PDSCH reception schematic 400 according to an embodiment of this disclosure. Assume tci-PresentInDCI is disabled. The UE can determine whether the time offset (e.g., PDSCH scheduling offset) between the DCI and the PDSCH resource indicated by the DCI is greater than or equal to timeDurationForQCL. Since the time offset corresponding to the first PDSCH is less than timeDurationForQCL, the UE can use the QCL assumption of a preset beam to receive the first PDSCH. Since the time offset corresponding to the second PDSCH (or the third or fourth PDSCH) is greater than or equal to timeDurationForQCL, the UE can use the QCL assumption of the DCI to receive the second PDSCH (or the third or fourth PDSCH). For example, if the UE has already received the DCI using a specific spatial filter, the UE can use the same spatial filter to receive the second PDSCH (or the third or fourth PDSCH).

[0014] In time division duplexing (TDD), time-domain resources are divided between the downlink (DL) and uplink (UL). Allocating a limited duration for the uplink in TDD results in reduced coverage and increased latency. The feasibility of allowing simultaneous downlink and uplink (i.e., full-duplex) in conventional TDD bands, or more specifically, allowing non-overlapping full-duplex subbands at the BS (e.g., gNB) end, warrants investigation. For SBFD operation, the gNB can use a first antenna setting to perform DL or UL in a non-SBFD symbol type, and can use a second antenna setting to perform both DL and UL simultaneously in an SBFD symbol type, where the second antenna setting can differ from the first antenna setting.

[0015] Figure 5 illustrates a schematic diagram 500 of a separate antenna configuration for a first symbol type and a second symbol type according to an embodiment of this disclosure, where "U" represents a time slot used for uplink transmission. The second symbol type may be different from the first symbol type, or the modulation and coding scheme (MCS) of the second symbol type may be different from the MCS of the first symbol type. For example, the first or second symbol type may include a non-SBFD symbol type, an SBFD symbol type, a symbol type used only for communication, a symbol type used for communication and sensing, a symbol type used for power saving mode, or a symbol type used for normal mode.

[0016] In this disclosure, embodiments applied to one set of symbol types can also be applied to another set of symbol types. For example, the QCL assumption method for determining SBFD symbol types and non-SBFD symbol types can also be applied to determining QCL assumptions for symbol types used only for communication and symbol types used for both communication and sensing, or to determining QCL assumptions for symbol types used for power-saving mode and symbol types used for normal mode.

[0017] Referring to Figure 5, antenna setting 1 can be applied to non-SBFD symbols. When antenna setting 1 is applied, the gNB can use both panels 1 and 2 to perform DL transmission or UL reception. Antenna setting 2 can be applied to SBFD symbols. When antenna setting 2 is applied, the gNB can use panel 1 to perform DL transmission and use panel 2 to perform UL reception.

[0018] Figure 6 illustrates a schematic diagram 600 of ISAC operation in different symbol types according to an embodiment of this disclosure. In integrated sensing and communication (ISAC) operation, the gNB may perform communication only within a symbol of a first symbol type, or may perform both communication and sensing within a symbol of a second symbol type. In ISAC operation, the gNB may use a first antenna setting to perform communication, and may use a second antenna setting to perform both communication and sensing.

[0019] Figure 7 illustrates a schematic diagram 700 of separate antenna settings of different symbol types according to an embodiment of this disclosure. Antenna setting 1 can be applied for communication only. When antenna setting 1 is applied, the gNB can use both panel 1 and panel 2 to perform DL transmission or UL reception. Antenna setting 2 can be applied for both communication and sensing. When antenna setting 2 is applied, the gNB can use panel 1 to perform both communication (e.g., DL transmission) and sensing (e.g., transmitting a sensing signal), or the gNB can use panel 2 to perform both communication (e.g., UL reception) and sensing (e.g., receiving a sensing signal).

[0020] Figure 8 illustrates a schematic diagram 800 of DL reception across different symbol types according to an embodiment of this disclosure. Multiple PDSCHs scheduled by a single DCI can span both non-SBFD symbol types and SBFD symbol types. For UL transmissions or DL ​​receptions spanning SBFD and non-SBFD symbols in different time slots (each transmission / reception within a time slot has all SBFD or all non-SBFD symbols), one of the following configurations can be provided to the SBFD-aware UE: Configuration 1: Transmissions / receptions can be in both SBFD and non-SBFD symbols, as shown in Figure 8; and Configuration 2: Transmissions / receptions can be restricted to SBFD symbols only or non-SBFD symbols only. Configuration 1 informs the UE to receive multiple PDSCHs across different symbol types. Configuration 2 informs the UE not to receive multiple PDSCHs across different symbol types.

[0021] In one embodiment, the configuration provided to the SBFD-aware UE may be related to the UE's capabilities. For example, if the UE reports its AcerSymType capability to the network, the network may configure Configuration 1 to the UE. The UE may perform UL transmissions across SBFD symbol types and non-SBFD symbol types based on Configuration 1, or the UE may perform DL receptions across SBFD symbol types and non-SBFD symbol types based on Configuration 1.

[0022] In one embodiment, the configurations (e.g., configuration 1 or 2) can be DL reception and UL transmission configurations, respectively. For example, if the UE reports acrossTwoSymType UL capability to the network, the network can configure UL transmission configuration 1 for the UE. The UE can perform UL transmissions across SBFD symbol types and non-SBFD symbol types based on configuration 1. For example, if the UE reports acrossTwoSymType DL capability to the network, the network can configure DL reception configuration 1 for the UE. The UE can perform DL reception across SBFD symbol types and non-SBFD symbol types based on configuration 1.

[0023] In one embodiment, configuration 1 or configuration 2 can be configured for a specific transmission / reception type, such as UL / DL transmission / reception configured at a higher layer. In one embodiment, for dynamically scheduled UL / DL transmission / reception, the UE can preset to perform UL / DL transmission / reception across SBFD symbol types and non-SBFD symbol types (if any).

[0024] Figure 9 illustrates a potential problem 900 in SBFD operation according to an embodiment of this disclosure. In one embodiment, the UE can use the same QCL assumption to receive multiple PDSCHs across different symbol types (e.g., non-SBFD symbol type and SBFD symbol type). However, the gNB can use different antenna settings for non-SBFD symbols and SBFD symbols respectively. If the UE uses only a single QCL assumption to receive multiple PDSCHs, the multi-PDSCH reception efficiency may be reduced.

[0025] Figure 10 illustrates a possible problem in ISAC operation according to an embodiment of this disclosure. In one embodiment, the UE can use the same QCL assumption to receive multiple PDSCHs across different symbol types (e.g., symbols used only for communication and symbols used for both communication and sensing). However, the gNB can use different antenna settings for different symbol types. If the UE uses only a single QCL assumption to receive multiple PDSCHs, the multi-PDSCH reception efficiency may be reduced.

[0026] In one embodiment, the UE may determine separate QCL assumptions for multiple PDSCH receptions in different symbol types.

[0027] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI. The first set of PDSCHs in the multiple PDSCHs can be associated with a first symbol type, and the second set of PDSCHs in the multiple PDSCHs can be associated with a second symbol type. If the UE receives DCI in the first symbol type, the UE can use the QCL assumptions of the DCI reception to receive the first set of PDSCHs, and the UE can use the QCL assumptions indicated by the DCI to receive the second set of PDSCHs. If the UE receives DCI in the second symbol type, the UE can use the QCL assumptions of the DCI reception to receive the second set of PDSCHs, and the UE can use the QCL assumptions indicated by the DCI to receive the first set of PDSCHs.

[0028] Figure 11 illustrates a multi-PDSCH reception schematic 1100 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set can be greater than or equal to timeDurationForQCL. Since the UE has already received DCI in a non-SBFD symbol type under the first QCL assumption, the UE can use the first QCL assumption to receive the first PDSCH set, and the UE can use the second QCL assumption to receive the second PDSCH set, wherein the second QCL assumption is indicated by the DCI. The second QCL assumption can be the same as or different from the first QCL assumption.

[0029] Figure 12 illustrates a multi-PDSCH reception schematic 1200 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set can be greater than or equal to timeDurationForQCL. Since the UE has already received DCI in the SBFD symbol type under the first QCL assumption, the UE can use the first QCL assumption to receive the second PDSCH set, and the UE can use the second QCL assumption to receive the first PDSCH set, wherein the second QCL assumption is indicated by the DCI. The second QCL assumption can be the same as or different from the first QCL assumption.

[0030] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI, where the PDSCH scheduling offset of one PDSCH set can be greater than or equal to timeDurationForQCL. The PDSCH set can be associated with a specific symbol type. If the UE receives DCI in a specific symbol type, the UE can use the QCL assumptions for DCI reception to receive the PDSCH set. The UE can ignore the TCI field in the DCI. If the UE receives DCI in other symbol types, the UE can use the QCL assumptions indicated by the DCI to receive the PDSCH set, where the QCL assumptions can be indicated by the TCI field in the DCI.

[0031] Figure 13 illustrates a multi-PDSCH reception schematic 1300 according to an embodiment of this disclosure, wherein the PDSCH set is associated with a non-SBFD symbol type. Since the UE has already received DCI in a non-SBFD symbol type, the UE can use the QCL assumption of DCI reception to receive the PDSCH set.

[0032] Figure 14 illustrates a multi-PDSCH reception schematic 1400 according to an embodiment of this disclosure, wherein the PDSCH set is associated with non-SBFD symbols. Since the UE has already received DCI in the SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the PDSCH set.

[0033] Figure 15 illustrates a QCL hypothesis selection flowchart according to an embodiment of this disclosure. In step S151, the UE may receive the DCI of the scheduled multiple PDSCHs. In step S152, the UE may determine whether the DCI is received in an SBFD symbol type. If the DCI is received in an SBFD symbol type, the UE may execute step S153. If the DCI is not received in an SBFD symbol type (e.g., the DCI is received in a non-SBFD symbol type), the UE may execute step S154. In step S153, the UE may use the QCL hypothesis received by the DCI to receive the PDSCH associated with the SBFD symbol type (if any). The UE may use the QCL hypothesis indicated by the DCI to receive the PDSCH associated with a non-SBFD symbol type (if any). In step S154, the UE may use the QCL hypothesis received by the DCI to receive the PDSCH associated with a non-SBFD symbol type (if any). The UE may use the QCL hypothesis indicated by the DCI to receive the PDSCH associated with the SBFD symbol type (if any).

[0034] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI, where the PDSCH scheduling offset of one PDSCH set in the multiple PDSCHs can be greater than or equal to timeDurationForQCL. The PDSCH set can be associated with a symbol type, and the QCL indicated by the DCI is assumed to be available for receiving the PDSCH set. The symbol type of the DCI can be the same as or different from the symbol type of the PDSCH set.

[0035] Figure 16 illustrates a multi-PDSCH reception schematic 1600 according to an embodiment of this disclosure, wherein the PDSCH set is associated only with non-SBFD symbol types. The UE can use the QCL assumption indicated by the DCI to receive the PDSCH set.

[0036] Figure 17 illustrates a flowchart of QCL hypothesis selection according to an embodiment of this disclosure. In step S171, the UE may receive the DCI of scheduled multiple PDSCHs. In step S172, the UE may determine whether the multiple PDSCHs span two symbol types. If the multiple PDSCHs span two symbol types, the UE may execute step S174. If the multiple PDSCHs do not span two symbol types, the UE may execute step S173. In step S173, the UE may use the QCL hypothesis indicated by the DCI to receive the multiple PDSCHs. In step S174, the UE may determine whether the DCI is received in an SBFD symbol type. If the DCI is received in an SBFD symbol type, the UE may execute step S175. If the DCI is not received in an SBFD symbol type (e.g., the DCI is received in a non-SBFD symbol type), the UE may execute step S176. In step S175, the UE may use the QCL hypothesis received by the DCI to receive the PDSCH associated with the SBFD symbol type (if any). The UE may use the QCL assumption indicated by the DCI to receive PDSCH (if any) related to non-SBFD symbol types. In step S176, the UE may use the QCL assumption received by the DCI to receive PDSCH (if any) related to non-SBFD symbol types. The UE may use the QCL assumption indicated by the DCI to receive PDSCH (if any) related to SBFD symbol types.

[0037] In one embodiment, the UE may assume that the serving cell's demodulation reference signal (DM-RS) port is quasi-co-addressable with one or more reference signals (RS), wherein the RS may be associated with QCL parameters for DCI quasi-co-address indication used for control resource set (CORESET). The CORESET may be associated with the monitoring search space having the lowest controlResourceSetID in the last time slot, wherein one or more CORESETs within the serving cell's active bandwidth part (BWP) in the last time slot may be monitored by the UE.

[0038] Figure 18 illustrates a PDSCH reception schematic 1800 according to an embodiment of this disclosure. The UE can determine whether the time offset (e.g., PDSCH scheduling offset) between the DCI and the PDSCH resource indicated by the DCI is greater than or equal to timeDurationForQCL. Since the time offset corresponding to the first PDSCH is less than timeDurationForQCL, the UE can use the QCL assumption of a preset beam to receive the first PDSCH. Since the time offset corresponding to the second PDSCH (or the third or fourth PDSCH) is greater than or equal to timeDurationForQCL, the UE can use the QCL assumption indicated by the TCI field of the DCI to receive the second PDSCH (or the third or fourth PDSCH).

[0039] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI. The first set of multiple PDSCHs can be associated with a first symbol type, and the second set of multiple PDSCHs can be associated with a second symbol type. If the UE receives DCI in the first symbol type, the QCL assumption indicated by the DCI can be used to receive the first PDSCH set, and the QCL assumption of the preset beam can be used to receive the second PDSCH set. If the UE receives DCI in the second symbol type, the QCL assumption indicated by the DCI can be used to receive the second PDSCH set, and the QCL assumption of the preset beam can be used to receive the first PDSCH set.

[0040] Figure 19 illustrates a PDSCH reception schematic 1900 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set may be greater than or equal to timeDurationForQCL. Since the UE has already received DCI in a non-SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the first PDSCH set, and the UE can use the QCL assumption of a preset beam to receive the second PDSCH set.

[0041] Figure 20 illustrates a PDSCH reception schematic 2000 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set can be greater than or equal to timeDurationForQCL. Since the UE has already received DCI in the SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the second PDSCH set, and the UE can use the QCL assumption of a preset beam to receive the first PDSCH set.

[0042] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI, and the multiple PDSCHs can be associated with a specific symbol type. If the UE receives the DCI in a specific symbol type, the UE can use the QCL assumption indicated by the DCI to receive the multiple PDSCHs. If the UE receives the DCI in other symbol types, the UE can use the QCL assumption of a preset beam to receive the multiple PDSCHs. The UE can ignore the TCI field in the DCI.

[0043] Figure 21 illustrates a PDSCH reception schematic 2100 according to an embodiment of this disclosure, wherein the PDSCH set is associated with the SBFD symbol type. It is assumed that the UE has already received DCI in the SBFD symbol type. Since DCI and multiple PDSCHs are associated with the same symbol type, the UE can use the QCL assumption indicated by the DCI to receive multiple PDSCHs.

[0044] Figure 22 illustrates a PDSCH reception schematic 2200 according to an embodiment of this disclosure, wherein the PDSCH set is associated with the SBFD symbol type. It is assumed that the UE has already received DCI in a non-SBFD symbol type. Since DCI and multiple PDSCHs are associated with different symbol types, the UE can use the QCL assumption of a preset beam to receive multiple PDSCHs.

[0045] Figure 23 illustrates a flowchart of QCL hypothesis selection according to an embodiment of this disclosure. In step S231, the UE may receive the DCI of the scheduled multiple PDSCHs. In step S232, the UE may determine whether the DCI is received in an SBFD symbol type. If the DCI is received in an SBFD symbol type, the UE may execute step S233. If the DCI is not received in an SBFD symbol type (e.g., the DCI is received in a non-SBFD symbol type), the UE may execute step S234. In step S233, the UE may use the QCL hypothesis indicated by the DCI to receive the PDSCH associated with the SBFD symbol type (if any). The UE may use the QCL hypothesis of a preset beam to receive the PDSCH associated with a non-SBFD symbol type (if any). In step S244, the UE may use the QCL hypothesis indicated by the DCI to receive the PDSCH associated with a non-SBFD symbol type (if any). The UE may use the QCL hypothesis of a preset beam to receive the PDSCH associated with the SBFD symbol type (if any).

[0046] Figure 24 illustrates a flowchart of QCL hypothesis selection according to an embodiment of this disclosure. In step S241, the UE may receive the DCI of scheduled multiple PDSCHs. In step S242, the UE may determine whether the multiple PDSCHs span two symbol types. If the multiple PDSCHs span two symbol types, the UE may execute step S244. If the multiple PDSCHs do not span two symbol types, the UE may execute step S243. In step S243, the UE may use the QCL hypothesis indicated by the DCI to receive the multiple PDSCHs. In step S244, the UE may determine whether the DCI is received in an SBFD symbol type. If the DCI is received in an SBFD symbol type, the UE may execute step S245. If the DCI is not received in an SBFD symbol type (e.g., the DCI is received in a non-SBFD symbol type), the UE may execute step S246. In step S245, the UE may use the QCL hypothesis indicated by the DCI to receive the PDSCH associated with the SBFD symbol type (if any). The UE can use the QCL assumption of a preset beam to receive PDSCH (if any) associated with a non-SBFD symbol type. In step S246, the UE can use the QCL assumption indicated by the DCI to receive PDSCH (if any) associated with a non-SBFD symbol type. The UE can use the QCL assumption of a preset beam to receive PDSCH (if any) associated with an SBFD symbol type.

[0047] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The first set of multiple PDSCHs can be associated with a first symbol type, and the second set of multiple PDSCHs can be associated with a second symbol type. If the first symbol type is an SBFD symbol type, the QCL assumption indicated by the DCI can be used to receive the first PDSCH set, and the QCL assumption of a preset beam can be used to receive the second PDSCH set. If the second symbol type is an SBFD symbol type, the QCL assumption indicated by the DCI can be used to receive the second PDSCH set, and the QCL assumption of a preset beam can be used to receive the first PDSCH set.

[0048] Figure 25 illustrates a PDSCH reception schematic 2500 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets may be greater than or equal to timeDurationForQCL. Assume the UE has already received DCI in a non-SBFD symbol type. Since the first PDSCH set is associated with a non-SBFD symbol type, the UE can use the QCL assumption of a preset beam to receive the first PDSCH set. Since the second PDSCH set is associated with an SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the second PDSCH set.

[0049] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The PDSCH scheduling offset of one PDSCH set among the multiple PDSCHs can be greater than or equal to timeDurationForQCL, wherein the PDSCH set can be associated with a specific symbol type. If the specific symbol type is a non-SBFD symbol type, the QCL assumption of a preset beam can be used to receive the PDSCH set. The UE can ignore the TCI field in the DCI. If the specific symbol type is an SBFD symbol type, the QCL assumption indicated by the DCI can be used to receive the PDSCH set.

[0050] Figure 26 illustrates a PDSCH reception schematic 2600 according to an embodiment of this disclosure, wherein the PDSCH set is associated with a non-SBFD symbol type. It is assumed that the UE has already received DCI in a non-SBFD symbol type. Since the PDSCH set is associated with a non-SBFD symbol type, the UE can use a preset beam QCL assumption to receive the PDSCH set.

[0051] Figure 27 illustrates a PDSCH reception schematic 2700 according to an embodiment of this disclosure, wherein the PDSCH set is associated with the SBFD symbol type. It is assumed that the UE has already received DCI in a non-SBFD symbol type. Since the PDSCH set is associated with the SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the PDSCH set.

[0052] Figure 28 illustrates a flowchart of QCL assumption selection according to an embodiment of this disclosure. In step S281, the UE can receive the DCI of the scheduled multiple PDSCHs. In step S282, the UE can use the QCL assumption indicated by the DCI to receive the PDSCH associated with the SBFD symbol type (if any). The UE can use the QCL assumption of a preset beam to receive the PDSCH associated with a non-SBFD symbol type (if any).

[0053] Figure 29 illustrates a flowchart of QCL assumption selection according to an embodiment of this disclosure. In step S291, the UE can receive the DCI of scheduled multiple PDSCHs. In step S292, the UE can determine whether the multiple PDSCHs span two symbol types. If the multiple PDSCHs span two symbol types, the UE can proceed to step S293. If the multiple PDSCHs do not span two symbol types, the UE can proceed to step S294. In step S293, the UE can use the QCL assumption indicated by the DCI to receive PDSCHs associated with SBFD symbol types (if any). The UE can use the QCL assumption of a preset beam to receive PDSCHs associated with non-SBFD symbol types (if any). In step S294, the UE can use the QCL assumption indicated by the DCI to receive multiple PDSCHs.

[0054] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The first set of multiple PDSCHs can be associated with a first symbol type, and the second set of multiple PDSCHs can be associated with a second symbol type. The first PDSCH in the first set can be closer to the DCI than the first PDSCH in the second set. That is, the time interval between the DCI and the first PDSCH in the first set can be less than the time interval between the DCI and the first PDSCH in the second set. A preset beam QCL assumption can be used to receive the first PDSCH set. A DCI-indicated QCL assumption can be used to receive the second PDSCH set.

[0055] Figure 30 illustrates a PDSCH reception schematic 3000 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets can be greater than or equal to timeDurationForQCL. Since the first PDSCH set is closer to the DCI, the UE can use the QCL assumption of a preset beam to receive the first PDSCH set. Since the first PDSCH set is farther from the DCI, the UE can use the QCL assumption indicated by the DCI to receive the second PDSCH set.

[0056] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI, and the PDSCH scheduling offset of the multiple PDSCH set can be greater than or equal to timeDurationForQCL, wherein the PDSCH set can be associated with a specific symbol type. The QCL of a preset beam is assumed to be available for receiving the PDSCH set. The UE can ignore the TCI field in the DCI.

[0057] Figure 31 illustrates a PDSCH reception schematic 3100 according to an embodiment of this disclosure, wherein the PDSCH set is associated with a non-SBFD symbol type. It is assumed that the UE has already received DCI in a non-SBFD symbol type. Since the PDSCH set is associated with a non-SBFD symbol type, the UE can use the QCL assumption of a preset beam to receive the PDSCH set.

[0058] Figure 32 illustrates a flowchart of QCL hypothesis selection according to an embodiment of this disclosure. In step S321, the UE may receive the DCI of scheduled multiple PDSCHs, wherein the multiple PDSCHs may include PDSCHs associated with SBFD symbol types and non-SBFD symbol types respectively. In step S322, the UE may determine whether the PDSCH associated with the non-SBFD symbol type is closer to the DCI. If the PDSCH associated with the non-SBFD symbol type is closer to the DCI, the UE may execute step S323. If the PDSCH associated with the SBFD symbol type is closer to the DCI, the UE may execute step S324. In step S323, the UE may use the QCL hypothesis of a preset beam to receive the PDSCH associated with the non-SBFD symbol type (if any). The UE may use the QCL hypothesis indicated by the DCI to receive the PDSCH associated with the SBFD symbol type (if any). In step S324, the UE may use the QCL hypothesis of the preset beam to receive the PDSCH associated with the SBFD symbol type (if any). The UE may use the QCL assumption indicated by the DCI to receive PDSCH (if any) associated with a non-SBFD symbol type.

[0059] Figure 33 illustrates a flowchart of QCL hypothesis selection according to an embodiment of this disclosure. In step S331, the UE can receive the DCI of scheduled multiple PDSCHs. In step S332, the UE can determine whether the multiple PDSCHs span two symbol types. If the multiple PDSCHs span two symbol types, the UE can proceed to step S334. If the multiple PDSCHs do not span two symbol types, the UE can proceed to step S333. In step S333, the UE can use the QCL hypothesis indicated by the DCI to receive the multiple PDSCHs. In step S334, the UE can determine whether the PDSCH associated with a non-SBFD symbol is closer to the DCI. If the PDSCH associated with a non-SBFD symbol is closer to the DCI, the UE can proceed to step S335. If the PDSCH associated with an SBFD symbol is closer to the DCI, the UE can proceed to step S336. In step S335, the UE can use the QCL hypothesis of a preset beam to receive the PDSCH associated with a non-SBFD symbol type (if any). The UE can use the QCL assumption indicated by the DCI to receive PDSCH related to the SBFD symbol type (if any). In step S336, the UE can use the QCL assumption of the preset beam to receive PDSCH related to the SBFD symbol type (if any). The UE can use the QCL assumption indicated by the DCI to receive PDSCH related to non-SBFD symbol types (if any).

[0060] The UE can be configured with a TCI state table, which can contain N TCI states, where N is a positive integer. Some code points in the TCI state table (e.g., the first N / 2 TCI states) can be associated with non-SBFD symbol types, while other code points (e.g., the last N / 2 TCI states) can be associated with SBFD symbol types. The network or UE can determine the bit length of the TCI field in the DCI based on the number of N TCI states or the number of N / 2 TCI states. For example, the number of TCI states for SBFD symbol types (e.g., N / 2 TCI states) can be the same as the number of TCI states for non-SBFD symbol types (e.g., N / 2 TCI states). If the number of TCI states of a symbol type is N / 2 indicated to the UE, the UE can determine that the total number of TCI states for both symbol types is equal to N, and the UE can correspondingly determine the bit length of the TCI field.

[0061] Table 1 shows an example of a TCI state table. Code points "00" and "01" can be associated with non-SBFD symbol types. Code points "10" and "11" can be associated with SBFD symbol types. Table 1 TCI column TCI Status Identification (ID) 00 #A0 01 #A1 10 #B0 11 #B1

[0062] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The first set of multiple PDSCHs can be associated with a first symbol type, and the second set of multiple PDSCHs can be associated with a second symbol type. If the code point in the TCI field of the DCI is associated with the first symbol type, the UE can use the QCL assumption of the corresponding code point to receive the first PDSCH set, and the UE can use the QCL assumption of a preset beam to receive the second PDSCH set. If the code point in the TCI field of the DCI is associated with the second symbol type, the UE can use the QCL assumption of the corresponding code point to receive the second PDSCH set, and the UE can use the QCL assumption of a preset beam to receive the first PDSCH set.

[0063] Figure 34 illustrates a PDSCH reception schematic 3400 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The UE may be configured with a TCI status table 340, which includes code points "00" and "01" corresponding to non-SBFD symbol types and code points "10" and "11" corresponding to SBFD symbol types. Assuming the UE has received a DCI, where the TCI field indicates code point "00" corresponding to a non-SBFD symbol type. Based on code point "00", the UE can use the QCL assumption corresponding to TCI status ID "#A0" to receive the first PDSCH set, and the UE can use the QCL assumption of a preset beam to receive the second PDSCH set.

[0064] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI, and the PDSCH scheduling offset of the multiple PDSCHs can be greater than or equal to timeDurationForQCL, wherein the multiple PDSCHs can be associated with a specific symbol type. The UE may not expect the code points of the TCI state in the DCI to be associated with other symbol types.

[0065] Figure 35 illustrates a PDSCH reception schematic 3500 according to an embodiment of this disclosure, wherein the PDSCH set is associated with a non-SBFD symbol type. The UE may be configured with a TCI state table 350, which includes code points "00" and "01" corresponding to non-SBFD symbol types and code points "10" and "11" corresponding to SBFD symbol types. Assume the UE has received a DCI, where the TCI field of the DCI indicates code point "10" corresponding to the SBFD symbol type. Since the PDSCH set is associated with a non-SBFD symbol type, the UE may not expect the code points in the TCI field of the DCI to be associated with the SBFD symbol type. Therefore, the UE may not use the TCI state corresponding to the indicated code point (i.e., "10") to receive the PDSCH set. In one example, the UE may use the TCI state of a preset beam or the TCI state used for receiving the DCI to receive the PDSCH set.

[0066] Figure 36 illustrates a QCL hypothesis selection flowchart according to an embodiment of this disclosure. In step S361, the UE may receive the DCI of scheduled multiple PDSCHs. In step S362, the UE may determine whether the multiple PDSCHs span two symbol types. If the multiple PDSCHs span two symbol types, the UE may execute step S364. If the multiple PDSCHs do not span two symbol types, the UE may execute step S363. In step S363, the UE may not expect the symbol type of the multiple PDSCHs to be different from the symbol type of the code point in the TCI field of the DCI. In step S364, the UE may determine whether the code point in the TCI field of the DCI is associated with a non-SBFD symbol type. If the code point is associated with a non-SBFD symbol type, the UE may execute step S365. If the code point is associated with an SBFD symbol type, the UE may execute step S366. In step S365, the UE may use the QCL hypothesis indicated by the DCI to receive the PDSCH associated with the non-SBFD symbol type (if any). The UE can use the QCL assumption of a preset beam to receive PDSCH (if any) related to the SBFD symbol type. In step S366, the UE can use the QCL assumption indicated by the DCI to receive PDSCH (if any) related to the SBFD symbol type. The UE can use the QCL assumption of a preset beam to receive PDSCH (if any) related to non-SBFD symbol types.

[0067] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI, and the PDSCH scheduling offset of the multiple PDSCHs can be greater than or equal to timeDurationForQCL, wherein the multiple PDSCHs can be associated with a specific symbol type. If the TCI state in the DCI is associated with other symbol types, the UE can use the QCL assumption of a preset beam to receive the multiple PDSCHs.

[0068] Figure 37 illustrates a PDSCH reception schematic 3700 according to an embodiment of this disclosure, wherein the PDSCH set is associated with a non-SBFD symbol type. The UE may be configured with a TCI status table 370, which includes code points "00" and "01" corresponding to non-SBFD symbol types and code points "10" and "11" corresponding to SBFD symbol types. Assuming the UE has received a DCI, where the TCI field of the DCI indicates code point "10" corresponding to the SBFD symbol type. Since the TCI field indicated by the DCI is associated with the SBFD symbol type, the UE can use a preset beam QCL assumption to receive the PDSCH set.

[0069] Figure 38 illustrates a QCL assumption selection flowchart according to an embodiment of this disclosure. In step S381, the UE can receive the DCI of scheduled multiple PDSCHs. In step S382, the UE can determine whether the multiple PDSCHs span two symbol types. If the multiple PDSCHs span two symbol types, the UE can proceed to step S384. If the multiple PDSCHs do not span two symbol types, the UE can proceed to step S383. In step S383, if the symbol type of the multiple PDSCHs is different from the symbol type of the code point in the TCI field of the DCI, the UE can use the QCL assumption of the preset beam to receive the multiple PDSCHs. In step S384, the UE can determine whether the code point in the TCI field of the DCI is associated with a non-SBFD symbol type. If the code point is associated with a non-SBFD symbol type, the UE can proceed to step S385. If the code point is associated with an SBFD symbol type, the UE can proceed to step S386. In step S385, the UE can use the QCL assumption indicated by the DCI to receive the PDSCH associated with a non-SBFD symbol type (if any). The UE can use the QCL assumption of a preset beam to receive PDSCH related to the SBFD symbol type (if any). In step S386, the UE can use the QCL assumption indicated by the DCI to receive PDSCH related to the SBFD symbol type (if any). The UE can use the QCL assumption of a preset beam to receive PDSCH related to non-SBFD symbol types (if any).

[0070] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI. The first set of multiple PDSCHs can be associated with a first symbol type, and the second set of multiple PDSCHs can be associated with a second symbol type. The TCI field in the DCI can point to one or more code points (e.g., two code points), the first code point can be associated with the first symbol type, and the second code point can be associated with the second symbol type. The UE can use the QCL assumption of the first code point to receive the first set of PDSCHs, and the UE can use the QCL assumption of the second code point to receive the second set of PDSCHs.

[0071] Figure 39 illustrates a PDSCH reception schematic 3900 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The UE may be configured with a TCI status table 390, which contains code points "0" and "1", each code point corresponding to both a non-SBFD symbol type and an SBFD symbol type. For example, code point "0" indicates the TCI status ID "#A0" corresponding to the non-SBFD symbol type and the TCI status ID "#B0" corresponding to the SBFD symbol type, and code point "1" indicates the TCI status ID "#A1" corresponding to the non-SBFD symbol type and the TCI status ID "#B1" corresponding to the SBFD symbol type. Assume the UE has received a DCI, where the code point in the TCI field of the DCI is "0". Based on code point "0", the UE can use the QCL assumption corresponding to TCI state ID "#A0" to receive the first PDSCH set, and the UE can use the QCL assumption corresponding to TCI state ID "#B0" to receive the second PDSCH set.

[0072] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. A first set of multiple PDSCHs can be associated with a first symbol type, and a second set of multiple PDSCHs can be associated with a second symbol type. The number of PDSCHs in the first set can be greater than the number of PDSCHs in the second set. A QCL assumption indicated by the DCI can be used to receive the first set of PDSCHs, and a QCL assumption with a preset beam can be used to receive the second set of PDSCHs.

[0073] Figure 40 illustrates a PDSCH reception schematic 4000 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type, wherein the number of the first PDSCH set is greater than the number of the second PDSCH set. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set may be greater than or equal to timeDurationForQCL. Since the number of the first PDSCH set is greater than the number of the second PDSCH set, the UE can use the QCL assumption indicated by the DCI to receive the first PDSCH set, and the UE can use the QCL assumption of a preset beam to receive the second PDSCH set.

[0074] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI. A first set of multiple PDSCHs can be associated with a first symbol type, and a second set of multiple PDSCHs can be associated with a second symbol type, wherein the number of PDSCHs in the first set can be equal to the number of PDSCHs in the second set. The UE can receive the first and second PDSCH sets according to any embodiment disclosed herein.

[0075] Figure 41 illustrates a PDSCH reception schematic 4100 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type, wherein the number of the first PDSCH set is equal to the number of the second PDSCH set. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set may be greater than or equal to timeDurationForQCL. Since the number of PDSCHs in the first PDSCH set is equal to the number of PDSCHs in the second PDSCH set, the UE can use a preset beam QCL assumption to receive the first PDSCH set (e.g., the first symbol type is a non-SBFD symbol type), and the UE can use a QCL assumption indicated by the DCI to receive the second PDSCH set (e.g., the second symbol type is an SBFD symbol type).

[0076] Figure 42 illustrates a QCL assumption selection flowchart according to an embodiment of this disclosure. In step S421, the UE may receive the DCI of scheduled multiple PDSCHs. In step S422, the UE may determine whether condition A is met. Specifically, the UE may determine whether the number of PDSCHs associated with non-SBFD symbol types is greater than the number of PDSCHs associated with SBFD symbol types. If the number of PDSCHs associated with non-SBFD symbol types is greater than the number of PDSCHs associated with SBFD symbol types, the UE may determine that condition A is met and proceed to step S423. If the number of PDSCHs associated with non-SBFD symbol types is less than the number of PDSCHs associated with SBFD symbol types, the UE may determine that condition A is not met and proceed to step S424. In step S423, the UE may use the QCL assumption indicated by the DCI to receive PDSCHs associated with non-SBFD symbol types (if any). The UE may use the QCL assumption of a preset beam to receive PDSCHs associated with SBFD symbol types (if any).

[0077] In step S424, the UE can determine whether condition B is satisfied. Specifically, the UE can determine whether the number of PDSCHs associated with non-SBFD symbol types is equal to the number of PDSCHs associated with SBFD symbol types. If the number of PDSCHs associated with non-SBFD symbol types is equal to the number of PDSCHs associated with SBFD symbol types, the UE can determine that condition B is satisfied and proceed to step S425. If the number of PDSCHs associated with non-SBFD symbol types is not equal to the number of PDSCHs associated with SBFD symbol types (i.e., the number of PDSCHs associated with non-SBFD symbol types is less than the number of PDSCHs associated with SBFD symbol types), the UE can determine that condition B is not satisfied and proceed to step S426. In step S425, the UE can receive multiple PDSCHs following any embodiment of this disclosure. In step S426, the UE can use the QCL assumption indicated by the DCI to receive PDSCHs associated with SBFD symbol types (if any). The UE can use the QCL assumption of a preset beam to receive PDSCHs associated with non-SBFD symbol types (if any).

[0078] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. A first set of multiple PDSCHs can be associated with a first symbol type, and a second set of multiple PDSCHs can be associated with a second symbol type. A TCI field indicated by the DCI can be applied to either the first or second symbol type. The symbol type to be applied to by the TCI field (e.g., the first or second symbol type) can be explicitly indicated by the DCI, radio resource control (RRC) configuration, or medium access control (MAC) control element (CE), or can be implicitly predefined by the specification. If the TCI field is applied to the first symbol type, the QCL assumption indicated by the DCI can be used to receive the first PDSCH set. A preset beam QCL assumption can be used to receive the second PDSCH set. If the TCI field is applied to the second symbol type, the QCL assumption indicated by the DCI can be used to receive the second PDSCH set, and the preset beam QCL assumption can be used to receive the first PDSCH set.

[0079] Figure 43 illustrates a PDSCH reception schematic 4300 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets may be greater than or equal to timeDurationForQCL. The UE may receive an indication (e.g., via DCI or other signaling) wherein the indication informs the UE that the TCI field of the DCI applies to the SBFD symbol type. Based on the indication, the UE can receive the second PDSCH set using the QCL assumption indicated by the DCI, and the UE can receive the first PDSCH set using the QCL assumption of a preset beam.

[0080] In one embodiment, the UE may be configured with one or more TCI state tables (e.g., two TCI state tables), wherein a first TCI state table may be associated with a first symbol type, and a second TCI state table may be associated with a second symbol type. In one embodiment, the number of TCI states in the first TCI state table may be the same as the number of TCI states in the second TCI state table. For example, the UE may be instructed to receive multiple PDSCHs spanning a first symbol type and a second symbol type. In response, the UE may be configured with a first TCI state table associated with the first symbol type and a second TCI state table associated with the second symbol type. Table 2 shows an example of a first TCI state table associated with a non-SBFD symbol type, and Table 3 shows an example of a second TCI state table associated with an SBFD symbol type. In one embodiment, the code point of the TCI field in the DCI may indicate a sequence. The UE may obtain the TCI state from the first TCI state table or from the second TCI state table using the sequence indicated by the DCI. For example, the code point "000" in the TCI field may indicate a first sequence. The UE can obtain the TCI status ID (e.g., #A0) from the first entry of the first TCI status table, or the UE can obtain the TCI status ID (e.g., #B0) from the first entry of the second TCI status table. Table 2 TCI column TCI Status ID 000 #A0 … … 111 #A7 Table 3 TCI column TCI Status Identification (ID) 000 #B0 … … 111 #B7

[0081] Figure 44 illustrates a PDSCH reception schematic 4400 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets may be greater than or equal to timeDurationForQCL. The UE may receive the DCI and obtain the code point of the TCI field in the DCI, wherein the TCI field may be applied to both the first and second TCI state tables. Assume the code point is "000". Since the first PDSCH set is associated with a non-SBFD symbol type, the UE may use the QCL assumption (e.g., #A0) indicated by the first TCI state table and the DCI to receive the first PDSCH set. Since the second PDSCH set is associated with an SBFD symbol type, the UE may use the QCL assumption (e.g., #B0) indicated by the second TCI state table and the DCI to receive the second PDSCH set.

[0082] Figure 45 illustrates a PDSCH reception schematic 4500 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets may be greater than or equal to timeDurationForQCL. Since the UE receives DCI in a non-SBFD symbol type, the UE can use the QCL assumption of the DCI reception to receive the first PDSCH set. The UE can use the QCL assumption indicated by the TCI field of the DCI to receive the second PDSCH set. Since the second PDSCH set is associated with an SBFD symbol type, the UE can obtain the QCL assumption from the second TCI status table according to the TCI field.

[0083] Figure 46 illustrates a PDSCH reception schematic 4600 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets can be greater than or equal to timeDurationForQCL. Since the number of PDSCHs in the first PDSCH set is greater than the number of PDSCHs in the second PDSCH set, the UE can use the QCL assumption indicated by the DCI to receive the first PDSCH set, and the UE can use the QCL assumption of a preset beam to receive the second PDSCH set. Since the first PDSCH set is associated with a non-SBFD symbol type, the UE can obtain the QCL assumption from the first TCI status table according to the TCI field of the DCI.

[0084] In one embodiment, the UE may be configured with a TCI state table, and each code point indicated by the TCI field in the DCI may be associated with a column of the TCI state table, wherein each column of the TCI state table may contain one or more TCI states (e.g., two TCI states), wherein the first TCI state may be associated with a first symbol type and the second TCI state may be associated with a second symbol type. Table 4 shows an example of a TCI state table. The code point "000" in the TCI field may indicate the first column of the TCI state table, wherein the first column contains the TCI state ID "#A0" corresponding to the first symbol type (e.g., non-SBFD symbol type) and the TCI state ID "#B0" corresponding to the second symbol type (e.g., SBFD symbol type). Table 4 TCI column TCI Status ID TCI Status ID 000 #A0 #B0 … … … 111 #A7 #B7

[0085] Figure 47 illustrates a PDSCH reception schematic 4700 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets may be greater than or equal to timeDurationForQCL. The UE may receive DCI and obtain code points from the TCI field of the DCI, wherein the code points may indicate a first TCI state corresponding to a non-SBFD symbol type and a second TCI state corresponding to an SBFD symbol type in the TCI state table. The UE may use the first TCI state indicated by the DCI to receive the first PDSCH set, and the UE may use the second TCI state indicated by the DCI to receive the second PDSCH set.

[0086] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. A first set of multiple PDSCHs may be associated with a first symbol type, and a second set of multiple PDSCHs may be associated with a second symbol type. The DCI may contain one or more TCI fields (e.g., two TCI fields). The first TCI field may be associated with the first symbol type, and the second TCI field may be associated with the second symbol type. The UE can receive the first PDSCH set using the QCL assumption indicated by the first TCI field. The UE can receive the second PDSCH set using the QCL assumption indicated by the second TCI field.

[0087] Figure 48 illustrates a PDSCH reception schematic 4800 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets may be greater than or equal to timeDurationForQCL. The UE may receive a DCI, wherein the DCI may contain a first TCI field associated with a non-SBFD symbol type and a second TCI field associated with an SBFD symbol type. The UE may receive the first PDSCH set using the QCL assumption indicated by the first TCI field. The UE may receive the second PDSCH set using the QCL assumption indicated by the second TCI field.

[0088] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The PDSCH scheduling offset of the multiple PDSCH set can be greater than or equal to timeDurationForQCL, and the PDSCH set can be associated with a specific symbol type. The DCI can contain one or more TCI fields (e.g., two TCI fields). The first TCI field can be associated with a first symbol type, and the second TCI field can be associated with a second symbol type. If the specific symbol type is the same as the first symbol type, the UE can receive the PDSCH set using the QCL assumption indicated by the first TCI field. The UE can ignore the second TCI field. If the specific symbol type is the same as the second symbol type, the UE can receive the PDSCH set using the QCL assumption indicated by the second TCI field. The UE can ignore the first TCI field.

[0089] Figure 49 illustrates a PDSCH reception schematic 4900 according to an embodiment of this disclosure, wherein the PDSCH set is associated with a non-SBFD symbol type. The PDSCH scheduling offset of the PDSCH set may be greater than or equal to timeDurationForQCL. The UE may receive a DCI, wherein the DCI may contain a first TCI field corresponding to a non-SBFD symbol type and a second TCI field corresponding to an SBFD symbol type. The UE may receive the PDSCH set using the QCL assumption indicated by the first TCI field. The UE may ignore the second TCI field in the DCI.

[0090] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The first set of multiple PDSCHs can be associated with a first symbol type, and the second set of multiple PDSCHs can be associated with a second symbol type. If the UE receives the DCI in the first symbol type, the QCL assumptions for DCI reception can be used to receive the first set of PDSCHs (if any). The QCL assumptions for a preset beam can be used to receive the second set of PDSCHs (if any). If the UE receives the DCI in the second symbol type, the QCL assumptions for DCI reception can be used to receive the second set of PDSCHs (if any). The QCL assumptions for a preset beam can be used to receive the first set of PDSCHs (if any).

[0091] Figure 50 illustrates a PDSCH reception schematic 5000 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets may be greater than or equal to timeDurationForQCL. Assume the UE has already received DCI in a non-SBFD symbol type. Since the first PDSCH set is associated with a non-SBFD symbol type, the UE can use the QCL assumption for DCI reception to receive the first PDSCH set. The UE can use the QCL assumption for a preset beam to receive the second PDSCH set.

[0092] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI. The first set of multiple PDSCHs can be associated with a first symbol type, and the second set of multiple PDSCHs can be associated with a second symbol type. The UE can use the QCL assumption of a preset beam to receive either the first set of PDSCHs or the second set of PDSCHs.

[0093] Referring to Figure 50. In one embodiment, since the UE has received the DCI and the DCI does not contain the TCI field, the UE can use the QCL assumption of the preset beam to receive the first PDSCH set and the second PDSCH set.

[0094] In one embodiment, the UE may be configured with a TCI state table, wherein the TCI state table may contain code points pointing to empty entries. Table 5 shows an example of a TCI state table containing code point "11" pointing to empty entries. Table 5 TCI column TCI Status ID 00 #A0 01 #A1 10 #A2 11 N / A

[0095] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI, and the PDSCH scheduling offset of the multiple PDSCH set can be greater than or equal to timeDurationForQCL, wherein the code point of the TCI field in the DCI can point to an empty entry in the TCI status table. In response to the code point pointing to an empty entry, the UE can correspondingly use the QCL assumption of a preset beam to receive the PDSCH set.

[0096] Figure 51 illustrates a PDSCH reception schematic 5100 according to an embodiment of this disclosure, wherein the PDSCH set may be associated with one or more symbol types. Assume the UE has received a DCI and the code point "11" in the TCI field of the DCI points to an empty entry in the TCI status table 510. In response to the code point "11" pointing to an empty entry in the TCI status table 510, the UE can use the QCL assumption of a preset beam to receive the PDSCH set.

[0097] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI. The first set of multiple PDSCHs can be associated with a first symbol type, and the second set of multiple PDSCHs can be associated with a second symbol type. The code points in the TCI field of the DCI can point to empty entries in the TCI state table. If the UE receives DCI in the first symbol type and the code points in the TCI field of the DCI point to empty entries in the TCI state table, the UE can use the QCL assumption of DCI reception to receive the first set of PDSCHs, and the UE can use the QCL assumption of a preset beam to receive the second set of PUSCHs. If the UE receives DCI in the second symbol type and the code points in the TCI field of the DCI point to empty entries in the TCI state table, the UE can use the QCL assumption of DCI reception to receive the second set of PDSCHs, and the UE can use the QCL assumption of a preset beam to receive the first set of PUSCHs.

[0098] Figure 52 illustrates a PDSCH reception schematic 5200 according to an embodiment of this disclosure, wherein a first PDSCH set may be associated with a non-SBFD symbol type and a second PDSCH set may be associated with an SBFD symbol type. Assume the UE has received DCI in a non-SBFD symbol type and the code point "11" in the TCI field of the DCI points to an empty entry in the TCI status table 520. In response to the code point "11" pointing to an empty entry in the TCI status table 520, the UE can use the QCL assumption of DCI reception to receive the first PDSCH set, and the UE can use the QCL assumption of a preset beam to receive the second PUSCH set.

[0099] For DCI repeated reception, the UE can receive the first DCI and the second DCI using the first QCL assumption and the second QCL assumption respectively. The UE can schedule multiple PDSCHs from the DCI. If one or more PDSCHs are related to the QCL assumption of the DCI reception, the UE can use the second QCL assumption to receive one or more PDSCHs.

[0100] For DCI repeated reception, the UE can receive the first DCI and the second DCI using the first QCL assumption and the second QCL assumption respectively. The UE can schedule multiple PDSCHs from the DCI. If one or more PDSCHs are related to the QCL assumption of the DCI reception, the UE can use the first QCL assumption to receive one or more PDSCHs.

[0101] Figure 53 illustrates a schematic diagram 5300 of DCI reception according to an embodiment of the present disclosure, wherein DCI reception may include first DCI reception and second DCI reception, and the plurality of cases may include: Case 1: The UE may use a first QCL assumption to receive the first DCI in a non-SBFD symbol type, and the UE may use a second QCL assumption to receive the second DCI in a non-SBFD symbol type; Case 2: The UE may use a first QCL assumption to receive the first DCI in a non-SBFD symbol type, and the UE may use a second QCL assumption to receive the second DCI in an SBFD symbol type; Case 3: The UE may use a first QCL assumption to receive the first DCI in an SBFD symbol type, and the UE may use a second QCL assumption to receive the second DCI in a non-SBFD symbol type; and Case 4: The UE may use a first QCL assumption to receive the first DCI in an SBFD symbol type, and the UE may use a second QCL assumption to receive the second DCI in an SBFD symbol type.

[0102] In one embodiment, when the UE is configured with SBFD resources, the UE may not be configured with DCI repetition. If the UE is configured with DCI repetition, the first DCI candidate resource and the second DCI candidate resource of the DCI repetition may not span different symbol types, or the first DCI candidate resource and the second DCI candidate resource of the DCI repetition may not overlap with the UL subband.

[0103] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. A first set of PDSCHs may be associated with a first symbol type, and a second set of PDSCHs may be associated with a second symbol type. The UE can provide one or more MCSs (e.g., two MCSs). The UE can receive the first and second PDSCH sets using the QCL assumption indicated by the DCI, where the first MCS can be applied to the first PDSCH set, and the second MCS and / or the first MCS can be applied to the second PDSCH set.

[0104] Figure 54 illustrates a PDSCH reception schematic 5400 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets may be greater than or equal to timeDurationForQCL. The UE may use the QCL assumption indicated by the DCI to receive the first and second PDSCH sets. Different MCSs may be applied to different symbol types. For example, the first MCS may be applied to the first PDSCH set, and a second MCS different from the first MCS may be applied to the second PDSCH set.

[0105] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The first PDSCH set in the multiple PDSCHs can be associated with a first symbol type, and the second PDSCH set in the multiple PDSCHs can be associated with a second symbol type. The UE can have a first MCS provided by the DCI and a second MCS provided by RRC configuration, MAC CE, or the DCI. The first MCS in the DCI can be applied to the first PDSCH set, and the first MCS and / or the second MCS can be applied to the second PDSCH set if the following conditions are met: the first symbol type is a non-SBFD symbol type, and the second symbol type is an SBFD symbol type; the first symbol type is an SBFD symbol type, and the second symbol type is a non-SBFD symbol type; the UE receives the DCI in the first symbol type; or the code point of the TCI field in the DCI is associated with the first symbol type. In one embodiment, the second MCS can be associated with an increment value (delta value) corresponding to the first MCS. For example, the second MCS can be equal to the sum of the first MCS and the increment value.

[0106] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. A first set of PDSCHs may be associated with a first symbol type, and a second set of PDSCHs may be associated with a second symbol type. The DCI may include an SBFD resource availability field with one bit. If the SBFD resource availability field indicates "1", the UE can receive the first PDSCH set using a first QCL assumption, and the UE can receive the second PDSCH set using a second QCL assumption. The first and second QCL assumptions can be determined by any embodiment in this disclosure. If the SBFD resource availability field indicates "0", the UE can receive the first and second PDSCH sets using the QCL assumption indicated by the DCI.

[0107] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI. The first set of PDSCHs in the multiple PDSCHs can be associated with a first symbol type, and the second set of PDSCHs in the multiple PDSCHs can be associated with a second symbol type. If the UE receives DCI in the first symbol type, the UE can use the QCL assumption indicated by the DCI to receive the first set of PDSCHs, and the UE may not receive the second set of PDSCHs. If the UE receives DCI in the second symbol type, the UE can use the QCL assumption indicated by the DCI to receive the second set of PDSCHs, and the UE may not receive the first set of PDSCHs.

[0108] Figure 55 illustrates a PDSCH reception schematic 5500 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set may be greater than or equal to timeDurationForQCL. Since the UE receives DCI in a non-SBFD symbol type, the UE can use the QCL indicated by the DCI to assume reception of the first PDSCH set, and the UE may not receive the second PDSCH set.

[0109] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI. The first set of PDSCHs in the multiple PDSCHs can be associated with a first symbol type, and the second set of PDSCHs in the multiple PDSCHs can be associated with a second symbol type. If the UE receives DCI in the first symbol type, the UE can use the QCL assumption indicated by the DCI to receive the second set of PDSCHs, and the UE may not receive the first set of PDSCHs. If the UE receives DCI in the second symbol type, the UE can use the QCL assumption indicated by the DCI to receive the first set of PDSCHs, and the UE may not receive the second set of PDSCHs.

[0110] In one embodiment, if the DCI does not contain a TCI field, the UE can perform DL reception using either the DCI reception or the QCL assumption of a preset beam, instead of using the QCL assumption indicated by the DCI.

[0111] Referring to Figure 55. In one embodiment, since the UE receives the DCI in a non-SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the second PDSCH set, and the UE may not receive the first PDSCH set.

[0112] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The first set of PDSCHs in the multiple PDSCHs can be associated with a first symbol type, and the second set of PDSCHs in the multiple PDSCHs can be associated with a second symbol type. If the first symbol type is an SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the first PDSCH set, and the UE may not receive the second PDSCH set. If the second symbol type is an SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the second PDSCH set, and the UE may not receive the first PDSCH set.

[0113] Referring to Figure 55. In one embodiment, since the second PDSCH set is associated with the SBFD symbol type, the UE can receive the second PDSCH set using the QCL assumption indicated by the DCI, and the UE may not receive the first PDSCH set.

[0114] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The first set of PDSCHs in the multiple PDSCHs can be associated with a first symbol type, and the second set of PDSCHs in the multiple PDSCHs can be associated with a second symbol type. If the first symbol type is not an SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the first PDSCH set, and the UE may not receive the second PDSCH set. If the second symbol type is not an SBFD symbol type, the UE can use the QCL assumption indicated by the DCI to receive the second PDSCH set, and the UE may not receive the first PDSCH set.

[0115] Referring to Figure 55. In one embodiment, since the first PDSCH set is associated with a non-SBFD symbol type, the UE can receive the first PDSCH set using the QCL assumption indicated by the DCI, and the UE may not receive the second PDSCH set.

[0116] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The first set of PDSCHs in the multiple PDSCHs can be associated with a first symbol type, and the second set of PDSCHs in the multiple PDSCHs can be associated with a second symbol type. The first PDSCH in the first set can be closer to the DCI than the first PDSCH in the second set. That is, the time interval between the DCI and the first PDSCH in the first set can be less than the time interval between the DCI and the first PDSCH in the second set. The UE can use the QCL assumption indicated by the DCI to receive the first PDSCH set, and the UE can choose not to receive the second PDSCH set.

[0117] Figure 56 illustrates a PDSCH reception schematic 5600 according to an embodiment of this disclosure, wherein a first PDSCH set is associated with a non-SBFD symbol type, and a second PDSCH set is associated with an SBFD symbol type. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set may be greater than or equal to timeDurationForQCL. It is assumed that the UE has already received DCI in a non-SBFD symbol type. Since the first PDSCH in the first PDSCH set is closer to the DCI, the UE can assume to receive the first PDSCH set using the QCL indicated by the DCI, and the UE may not receive the second PDSCH set.

[0118] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. A first set of PDSCHs in the multiple PDSCHs can be associated with a first symbol type, and a second set of PDSCHs in the multiple PDSCHs can be associated with a second symbol type. The first PDSCH in the first set can be closer to the DCI than the first PDSCH in the second set. The UE can receive the second PDSCH set using the QCL assumption indicated by the DCI, and the UE may choose not to receive the first PDSCH set.

[0119] Referring to Figure 56. In one embodiment, since the first PDSCH in the first PDSCH set is closer to the DCI, the UE can use the QCL assumption indicated by the DCI to receive the second PDSCH set, and the UE may not receive the first PDSCH set.

[0120] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. The first PDSCH set in the multiple PDSCHs can be associated with a first symbol type, and the second PDSCH set in the multiple PDSCHs can be associated with a second symbol type. If the code point in the TCI field of the DCI is associated with the first symbol type, the UE can use the QCL assumption of the corresponding code point to receive the first PDSCH set, and the UE may not receive the second PDSCH set. If the code point in the TCI field of the DCI is associated with the second symbol type, the UE can use the QCL assumption of the corresponding code point to receive the second PDSCH set, and the UE may not receive the first PDSCH set.

[0121] Figure 57 illustrates a PDSCH reception schematic 5700 according to an embodiment of this disclosure, wherein a first PDSCH set may be associated with a non-SBFD symbol type and a second PDSCH set may be associated with an SBFD symbol type. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set may be greater than or equal to timeDurationForQCL. Assume that the UE has already received DCI in a non-SBFD symbol type and the code point "00" in the TCI field of the DCI is associated with a non-SBFD symbol type. In response to the code point "00" being associated with a non-SBFD symbol type, the UE may assume to receive the first PDSCH set using the QCL corresponding to the TCI state ID "#A0", and the UE may choose not to receive the second PDSCH set.

[0122] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. A first set of PDSCHs may be associated with a first symbol type, and a second set of PDSCHs may be associated with a second symbol type. The number of PDSCHs in the first set may be greater than the number of PDSCHs in the second set. The UE can receive the first set of PDSCHs using the QCL assumption indicated by the DCI, and the UE may choose not to receive the second set of PDSCHs.

[0123] Figure 58 illustrates a PDSCH reception schematic 5800 according to an embodiment of this disclosure, wherein a first PDSCH set may be associated with a non-SBFD symbol type and a second PDSCH set may be associated with an SBFD symbol type. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set may be greater than or equal to timeDurationForQCL. Since there are more PDSCHs in the first PDSCH set, the UE can use the QCL indicated by the DCI to receive the first PDSCH set, and the UE may not receive the second PDSCH set.

[0124] In one embodiment, the UE can receive multiple PDSCHs scheduled by DCI. A first set of PDSCHs in the multiple PDSCHs can be associated with a first symbol type, and a second set of PDSCHs in the multiple PDSCHs can be associated with a second symbol type. The number of PDSCHs in the first set of PDSCHs can be equal to the number of PDSCHs in the second set of PDSCHs. The UE can receive either the first set of PDSCHs or the second set of PDSCHs according to any embodiment disclosed herein.

[0125] In one embodiment, the UE can receive multiple PDSCHs scheduled by the DCI. A first set of PDSCHs in the multiple PDSCHs can be associated with a first symbol type, and a second set of PDSCHs in the multiple PDSCHs can be associated with a second symbol type. The symbol type applied by the TCI field (e.g., the first symbol type or the second symbol type) can be explicitly indicated by the DCI, RRC configuration, or MAC CE, or can be implicitly predetermined by the specification. If the TCI field is applied to the first symbol type, the UE can use the QCL assumption indicated by the DCI to receive the first PDSCH set, and the UE may not receive the second PDSCH set. If the TCI field is applied to the second symbol type, the UE can use the QCL assumption indicated by the DCI to receive the second PDSCH set, and the UE may not receive the first PDSCH set.

[0126] Figure 59 illustrates a PDSCH reception schematic 5900 according to an embodiment of this disclosure, wherein a first PDSCH set may be associated with a non-SBFD symbol type and a second PDSCH set may be associated with an SBFD symbol type. The PDSCH scheduling offset of the first PDSCH set and the second PDSCH set may be greater than or equal to timeDurationForQCL. The UE may receive an indication that informs the UE that the TCI field of the DCI is applied to the SBFD symbol type. Since the TCI field of the DCI is applied to the SBFD symbol type, the UE may use the QCL indicated by the DCI to assume reception of the second PDSCH set, and the UE may not receive the first PDSCH set.

[0127] In one embodiment, for a DCI receiving multiple PDSCHs scheduled by the DCI, the first set of PDSCHs may be associated with a first symbol type, and the second set of PDSCHs may be associated with a second symbol type. The hybrid automatic repeat request (HARQ) acknowledgment (ACK) information corresponding to the multiple PDSCHs scheduled by the DCI can be multiplexed with a single entity uplink control channel (PUCCH), where the PUCCH can be in a time slot determined based on K1. K1 can be indicated by the PDSCH-to-HARQ_feedback timing indicator field in the DCI. If the PDSCH-to-HARQ_feedback timing indicator field does not exist in the DCI, K1 can be provided by dl-DataToUL-ACK. K1 can indicate the time slot offset between the time slot of the last PDSCH scheduled by the DCI and the time slot carrying the HARQ-ACK information of the corresponding multiple PDSCHs. If the final PDSCH is related to the first symbol type, the UE can use the QCL assumption indicated by the DCI to receive the first PDSCH set, and the UE may not receive the second PDSCH set. If the final PDSCH is related to the second symbol type, the UE can use the QCL assumption indicated by the DCI to receive the second PDSCH set, and the UE may not receive the first PDSCH set.

[0128] Figure 60 illustrates a PDSCH reception schematic 6000 according to an embodiment of this disclosure, wherein a first PDSCH set may be associated with a non-SBFD symbol type and a second PDSCH set may be associated with an SBFD symbol type. The PDSCH scheduling offset of the first and second PDSCH sets may be greater than or equal to timeDurationForQCL. The UE may receive the DCI and obtain K1 (e.g., K1=1) from the PDSCH to HARQ_feedback timing indication field in the DCI. Since the last PDSCH is associated with the SBFD symbol type, the UE may assume that it receives the second PDSCH set using the QCL indicated by the DCI, and the UE may not receive the first PDSCH set.

[0129] Figure 61 illustrates a flowchart of a method for receiving multiple PDSCHs according to an embodiment of the present disclosure, wherein the method can be performed by a UE. In step S611, downlink control information (DCI) is received from the network, wherein the DCI indicates the reception of multiple PDSCHs.

[0130] Figure 62 illustrates a schematic diagram of a UE 620 according to an embodiment of the present disclosure, wherein the UE 620 may implement the methods described in Figures 1-61, as well as exemplary embodiments and alternative variations thereof. The UE 620 may include a processor 621, a storage medium 622, and a transceiver 623. The processor 621 is coupled to the storage medium 622 and the transceiver 623.

[0131] Processor 621 can be implemented using programmable units, such as microprocessors, microcontrollers, digital signal processors (DSPs), field-programmable gate arrays (FPGAs), etc. The functionality of processor 621 can also be implemented by discrete electronic devices or ICs. It should be noted that the functionality of processor 621 can be implemented in hardware or software.

[0132] Storage media 622 may be, for example, any type of fixed or removable random access memory (RAM), read-only memory (ROM), flash memory, hard disk drive (HDD), solid state drive (SSD), or similar element, or a combination thereof, configured to record multiple modules or various applications executable by processor 621.

[0133] Transceiver 623 can be configured to transmit and receive signals separately in radio frequency. Transceiver 623 can also perform operations such as low-noise amplification, impedance matching, frequency mixing, up- or down-frequency conversion, filtering, and amplification. Transceiver 623 may include one or more digital-to-analog (D / A) converters or analog-to-digital (A / D) converters configured to convert from analog signal format to digital signal format during uplink signal processing and from digital signal format to analog signal format during downlink signal processing. Transceiver 623 may include an antenna array, which may include one or more antennas to transmit and receive omnidirectional or directional antenna beams.

[0134] The concept of "different symbol types" can be applied to: SBFD (e.g., a first symbol type that is not SBFD and a second symbol type that is SBFD); ISAC (e.g., a first symbol type that only communicates and a second symbol type that combines communication and sensing); or network energy saving (NES) (e.g., a first symbol type that is power-saving mode and a second symbol type that is normal mode).

[0135] The multiple PDSCHs in this disclosure can be: PDSCH repetitions (PDSCH repetitions can span SBFD symbol types and non-SBFD symbol types in different time slots, where each repetition has all SBFD symbol types or all non-SBFD symbol types); or multiple PDSCHs scheduled by a single DCI (multiple PDSCHs scheduled by a single DCI can span SBFD symbol types and non-SBFD symbol types in different time slots, where each PDSCH has all SBFD symbol types or all non-SBFD symbol types).

[0136] For multi-PDSCH reception spanning SBFD and non-SBFD symbol types across different time slots (each PDSCH having all SBFD symbol types or all non-SBFD symbol types), the following options can be applied: Option 1: Separate frequency domain resource allocation (FDRA) configuration / indication / interpretation can be applied to both SBFD and non-SBFD symbol types; Option 2: A single FDRA configuration / indication can be applied to one symbol type (e.g., SBFD or non-SBFD symbol type), and one or more resource block (RB) offset configuration / indication / determination can be provided to the UE to determine resources for other symbol types; Option 3: Physical resource blocks available in the DL within the time slot and in the SBFD symbol type. PDSCHs overlapping with RBs outside of a block (PRB) can be invalid (e.g., PDSCHs in a time slot can be discarded); Option 4: Only PDSCHs in one symbol type can be valid, while PDSCHs in other symbol types can be invalid; Option 5: For PDSCHs overlapping with RBs outside of the DL available PRB in a time slot within an SBFD symbol, only the assigned PRB within the DL available PRB can be considered valid; or Option 6: The gNB can not schedule any PDSCHs in the SBFD symbol type within a time slot to allow PDSCHs to overlap with PRBs outside of the DL available PRB.

[0137] The network (or BS) in this disclosure may be a cell, service cell, transmission reception point (TRP), unlicensed cell, unlicensed service cell, unlicensed TRP, next generation node B (gNodeB), gNB, eNodeB (evolved node B), or eNB, but is not limited to these.

[0138] Combinations of the embodiments disclosed in this disclosure are not excluded.

[0139] Based on the above, some low-complexity or low-cost UEs may not be able to support simultaneous reception of multiple downlink shared channels across different symbol types. These limitations require the BS to adjust scheduling strategies or transmission configurations according to the UE's capabilities. This disclosure provides a solution that enables accurate downlink reception at the UE even when downlink transmissions cross different symbol types. The UE disclosed in this disclosure can determine whether to receive multiple PDSCHs across different symbol types based on the reception configuration related to the UE's capabilities. If the UE determines that it will not receive multiple PDSCHs across different symbol types, the UE can determine the configuration of the symbols to be received and receive the symbols accordingly. If the UE determines that it will receive multiple PDSCHs across different symbol types, the UE can apply various configurations (e.g., TCI states) to receive multiple PDSCHs.
