Description

Technical Field

[0001] This disclosure generally relates to methods of using user equipment, methods of using network equipment, and user equipment. Background Technology

[0002] Figure 1 This is a schematic diagram illustrating static time division duplex (TDD) and sub-band full duplex (SBFD). (Reference) Figure 1 In duplex operation, a new type of time resource, SBFD, is introduced. In SBFD, the downlink (DL) and uplink (UL) subbands are allocated in the same symbol. However, in Time Division Duplex (TDD), the DL and UL bands are not allocated in the same symbol.

[0003] Figure 2 This is a schematic diagram illustrating simultaneous transmission (Tx) and reception (Rx) in a multi-panel transmission scheme. (Reference) Figure 2 To achieve simultaneous Tx / Rx and reduce adjacent channel interference, separate antenna panels can be supported. For example, panel 1 can be used for UL transmission and panel 2 for DL ​​reception. However, the same beam used for DL ​​reception (e.g., beam #A) may be present not only in SBFD resources but also in non-SBFD resources, leading to performance degradation due to improper beam application for DL ​​reception in both SBFD and non-SBFD resources.

[0302] Figure 12 This is a schematic diagram illustrating a wireless communication network architecture 1 according to an exemplary embodiment of the present disclosure. (See reference...) Figure 12 A wireless communication network architecture 1 (e.g., a Long Term Evolution (LTE) system, an LTE-Advanced (LTE-A) system, an LTE-AdvancedPro system, or a 5G NR Radio Access Network (RAN)) typically includes at least one base station (BS) NW, at least one user equipment (UE), and one or more optional network elements providing connectivity to the network. The UE communicates with the network (e.g., a core network (CN), an evolved packet core (EPC) network, an evolved public terrestrial radio access network (E-UTRAN), a 5G core (5GC), or the Internet) through the RAN established by one or more base stations.

[0303] It should be noted that in this disclosure, user equipment may include, but is not limited to, mobile stations, mobile terminals or devices, or user communication wireless terminals. For example, user equipment may be a portable wireless device, which includes, but is not limited to, mobile phones, tablets, wearable devices, sensors, vehicles, or personal digital assistants (PDAs) with wireless communication capabilities. User equipment is configured to receive and transmit signals to one or more cells in a wireless access network via an air interface.

[0304] The base station NW may be configured to provide communication services according to at least one of the following radio access technologies (RATs): Global Microwave Access Interoperability (WiMAX), Global System for Mobile Communications (GSM, commonly referred to as 2G), GSM Enhanced Data Rate Evolution of GSM (GERAN), Public Packet Radio Service (GPRS), Public Mobile Communications System based on Basic Wideband Code Division Multiple Access (W-CDMA) (UMTS, commonly referred to as 3G), High-Speed ​​Packet Access (HSPA), LTE, LTE-A, eLTE (evolved LTE, e.g., LTE connected to 5GC), NR (commonly referred to as 5G), and / or LTE-A Pro. However, the scope of this disclosure should not be limited to the protocols mentioned above.

[0305] A base station (NW) may include, but is not limited to, a Node B (NB) in UMTS, an Evolved Node B (eNB) in LTE or LTE-A, a Radio Network Controller (RNC) in UMTS, a Base Station Controller (BSC) in a GSM / GSM Enhanced Data Rate GSM Evolution (EDGE) Radio Access Network (GERAN), a Next Generation eNB (ng-eNB) in an Evolved Public Terrestrial Radio Access (E-UTRA) BS connected to a 5GC, a Next Generation Node B (gNB) in a 5G Access Network (5G-AN), and any other means capable of controlling wireless communications and managing radio resources within the cell. The base station NW may connect to the network via a radio interface to serve one or more user equipment.

[0306] A base station (BS) NW (or network device) may be able to provide radio coverage for a specific geographic area using multiple cells included in the RAN. The base station NW may support cell operation. Each cell may be able to provide service to at least one user equipment (UE) within its radio coverage area. Specifically, each cell (often referred to as the serving cell) may provide service within its radio coverage area to serve one or more UEs (e.g., each cell schedules downlink (DL) and optional uplink (UL) resources for at least one UE within its radio coverage area for DL ​​and optional UL packet transmission). The base station NW may communicate with one or more UEs in a wireless communication system through multiple cells. It should be noted that for UL, the UE is the transmitter performing UL transmission, and the network (node) is the receiver performing UL reception. For DL, the UE is the receiver performing DL reception, and the network (node) is the transmitter performing DL transmission.

[0307] A base station NW may include a network node NN and one or more transceiver points, such as transceiver point #1 and transceiver point #2.

[0308] A network node NN may be, but is not limited to, a node B (NB) in LTE, an evolved node B (eNB) in LTE-A, a radio network controller (RNC) in UMTS, a base station controller (BSC) in GSM / GERAN, a new radio evolution node B (NR eNB) in NR, a next-generation node B (gNB) in NR, and any other device capable of controlling wireless communications and managing radio resources within one or more cells.

[0309] Transceiver points (e.g., transceiver point #1 or transceiver point #2), which may also be considered remote radio heads (RRHs), are transceivers under 5G NR and / or 4G wireless communication system protocols. Transceiver points may be communicatively connected to a network node (NN). A network node (NN) may be connected in the wireless communication system through one or more transceiver points to serve one or more user equipments (UEs). For example, transceiver points #1 and #2 serve one U.S. UE, while transceiver point #2 serves another U.S. UE, but this is not a limitation.

[0310] As mentioned above, the NR frame structure is designed to support flexible configuration to accommodate various next-generation (e.g., 5G) communication requirements, such as enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC), while meeting high reliability, high data rate, and low latency requirements. The orthogonal frequency division multiplexing (OFDM) technology agreed upon in 3GPP may serve as the baseline for the NR waveform. Scalable OFDM parameters, such as adaptive subcarrier spacing, channel bandwidth, and cyclic prefix (CP), may also be used. Furthermore, NR considers two coding schemes: (1) low-density parity-check (LDPC) codes and (2) polar codes. Coding scheme adaptation may be configured based on channel conditions and / or service applications.

[0311] It should be understood that the terms "system" and "network" used in this disclosure are generally used interchangeably. The term "and / or" in this disclosure describes the relationship between related objects only, meaning that there can be three relationships, for example, A and / or B, which can represent three cases: A exists alone, A and B exist simultaneously, or B exists alone. In addition, the character " / " in this disclosure generally indicates that related objects are in an "or" relationship.

[0312] To facilitate understanding of the technical solutions of the embodiments of this disclosure, the technical concepts related to the embodiments of this disclosure are described below.

[0313] It should be noted that downlink (e.g., Physical Downlink Control Channel, PDCCH) receptions may exist with a transmission configuration indication state, regardless of resource type. However, downlink (e.g., PDCCH) receptions may have an inappropriate transmission configuration indication state on duplex operation with subband full-duplex resources, leading to downlink channel detection failure. Therefore, for downlink (e.g., PDCCH) receptions on duplex operation, the transmission configuration indication state per resource type will be considered. Furthermore, spatial domain filter determination for searching the spatial set monitoring will be considered.

[0314] Figure 13 This is a flowchart illustrating a method according to an exemplary embodiment of the present disclosure. (See reference...) Figure 13 This method can be implemented by a user equipment. The user equipment receives a search space (SS) set configuration (step S1310). Specifically, the SS set configuration corresponding to the SS set configuration includes a first control resource set (CORESET). The first CORESET is configured with a first transmission configuration indication (TCI) state. The first TCI state is configured with a reference reference signal (RS). Furthermore, the reference RS is associated with spatial receiver (Rx) parameters. In one embodiment, the first CORESET is further associated with a serving cell identifier (ID). For example, the serving cell ID of base station NW, transceiver point #1, or transceiver point #2. The user equipment receives downlink control information (DCI) according to the SS set configuration (step S1320).

[0315] In one embodiment, the user equipment may be configured to receive a DCI or SS set associated with at least one of the following: a first resource type or a second resource type. The DCI may be, for example, a PDCCH. The downlink may be, for example, a PDCCH. In one embodiment, the received DCI or SS set is associated with a first resource type and a second resource type.

[0316] In one embodiment, a first resource type is associated with subband full-duplex or downlink. The first resource type can be, for example, subband full-duplex associated with subband full-duplex. However, the first resource type can also be, for example, non-subband full-duplex, such as TDD with downlink. A second resource type can be, for example, subband full-duplex associated with subband full-duplex. However, the second resource type can also be, for example, non-subband full-duplex, such as TDD with downlink.

[0317] In one embodiment, the SS set is configured with a second CORESET, the second CORESET is configured with a second TCI state, the first CORESET is associated with a first resource type, and the second CORESET is associated with a second resource type. In one embodiment, when monitoring the SS set in the first resource type, the user equipment can receive DCI through the first CORESET with the first TCI state. When monitoring the SS set in the second resource type, the user equipment can receive DCI through the second CORESET with the second TCI state.

[0318] In one embodiment, CORESET may be activated / configured to have a new field for applying at least one of the following: for example, non-subband full-duplex symbol, subband full-duplex symbol, or both non-subband full-duplex and subband full-duplex symbols.

[0319] Non-subband full-duplex symbol:

[0320] User equipment can monitor the SS set associated with CORESET in non-subband full-duplex symbols.

[0321] User equipment may not expect to monitor the SS set associated with CORESET in the subband full-duplex symbol.

[0322] Sub-band full-duplex symbol:

[0323] User equipment can monitor the SS set associated with CORESET in subband full-duplex symbols.

[0324] User equipment may not be expected to monitor the SS set associated with CORESET in non-subband full-duplex symbols.

[0325] Both non-subband full-duplex and subband full-duplex symbols:

[0326] User equipment can monitor the SS set associated with CORESET in both subband full-duplex symbols and non-subband full-duplex symbols.

[0327] For example, Figure 14A This is a schematic diagram illustrating an SS set associated with two control resource sets (CORESETs) according to an example embodiment of this disclosure. Figure 14B This is a schematic diagram illustrating resource allocation for monitoring an SS set according to an example embodiment of this disclosure. (Reference) Figure 14A and Figure 4BCORESET#1, associated with the first transmission configuration indication state, is configured as non-subband full-duplex, while CORESET#2, associated with the second transmission configuration indication state, is configured as subband full-duplex. The user equipment can then monitor the SS set in CORESET#1 through the first transmission configuration indication state and the SS set in CORESET#2 through the second transmission configuration indication state. The user equipment then receives downlink control information through CORESET#1 associated with the first transmission configuration indication state and through CORESET#2 associated with the second transmission configuration indication state.

[0328] In one embodiment, CORESET can be activated / configured to have a new field for applying at least one of the following: For example, both non-subband full-duplex and subband full-duplex symbols. The user equipment can monitor the SS set associated with CORESET in both subband full-duplex symbols and non-subband full-duplex symbols.

[0329] For example, Figure 15A This is a schematic diagram illustrating a common type SS set for non-subband full-duplex and subband full-duplex symbols according to an example embodiment of this disclosure. Figure 15B This is a schematic diagram illustrating resource allocation for monitoring an SS set according to an example embodiment of this disclosure. (Reference) Figure 15A and Figure 15B An SS set ID can be associated with / configured with one or more CORESET IDs. The type of the SS set can be a public type with an ID of 0. The first transmission configuration indication state associated with the CORESET ID is associated with / configured with both subband full-duplex symbols and non-subband full-duplex symbols. Therefore, the user equipment can monitor the SS set through the same transmission configuration indication state (e.g., the first transmission configuration indication state).

[0330] Figure 16 This is a flowchart illustrating an SS set associated with one or two CORESETs according to an example embodiment of this disclosure. (Reference) Figure 16To identify the association of SS sets, the user equipment can identify the number of CORESETs associated with the SS set (step S1610). When (or in some cases) a CORESET is associated with an SS set, the user equipment can identify the type of the SS set associated with the CORESET (step S1620). When (or in some cases) the type of the SS set is a common type, a transmission configuration indication state (e.g., a first transmission configuration indication state) associated with the CORESETID (e.g., 0) is associated / configured with both subband full-duplex symbols and non-subband full-duplex symbols. When (or in some cases) the type of the SS set is a user equipment-specific type, a transmission configuration indication state (e.g., a third transmission configuration indication state) associated with the CORESET ID (e.g., 2) is associated / configured with both subband full-duplex symbols and non-subband full-duplex symbols.

[0331] When (or in certain circumstances) two CORESETs are associated with an SS set, the user equipment can identify the type of the SS set associated with the CORESET (step S1630). When (or in certain circumstances) the type of the SS set is a common type, the two transmission configuration indication states (e.g., the first transmission configuration indication state and the second transmission configuration indication state) associated with the CORESET ID (e.g., 0 and 1) are associated / configured with non-subband full-duplex symbols and subband full-duplex symbols, respectively. When (or in certain circumstances) the type of the SS set is a user equipment-specific type, the two transmission configuration indication states (e.g., the first transmission configuration indication state and the second transmission configuration indication state) associated with the CORESET ID (e.g., 0 and 1) are associated / configured with non-subband full-duplex symbols and subband full-duplex symbols, respectively.

[0332] In one embodiment, a first CORESET is configured to have a second transport configuration indication state, the first transport configuration indication state being associated with a first resource type, and the second transport configuration indication state being associated with a second resource type. That is, a CORESET is configured with two transport configuration indication states, each associated with a different resource type.

[0333] In one embodiment, the SS set is configured as a user equipment (UE) specific type. When the SS set is monitored in a first resource type, the UE can receive downlink control information through a first CORESET with a first transmission configuration indication state, and / or when the SS set is monitored in a second resource type, the UE can receive downlink control information through a first CORESET with a second transmission configuration indication state.

[0334] Figure 17A This is a schematic diagram illustrating example embodiments of the present disclosure for user equipment-specific types of SS sets for non-subband full-duplex and subband full-duplex symbols. Reference Figure 17A CORESET can be activated / configured to have a first transport configuration indication state and / or a second transport configuration indication state, wherein

[0335] The non-subband full-duplex symbol is associated with the first transmission configuration indication state.

[0336] The subband full-duplex symbol is associated with the second transmission configuration indication state.

[0337] Figure 17B This is a schematic diagram illustrating resource allocation for monitoring an SS set according to an example embodiment of this disclosure. (Reference) Figure 17B When (or under certain circumstances) monitoring of the first search space occurs simultaneously in both subband full-duplex and non-subband full-duplex symbols and / or the first SS is configured as a user equipment-specific type, such as Figure 17A As shown,

[0338] User equipment can monitor the first search space in non-subband full-duplex symbols through the first transmission configuration indication state, and / or

[0339] User equipment can monitor the first search space in the subband full-duplex symbol by indicating the status through the second transmission configuration.

[0340] Then, if a user equipment-specific SS set is monitored through a first transmission configuration indication state, the user equipment can receive downlink control information through a CORESET with the first transmission configuration indication state. Alternatively, if a user equipment-specific SS set is monitored through a second transmission configuration indication state, the user equipment can receive downlink control information through a CORESET with the second transmission configuration indication state.

[0341] In one embodiment, a first CORESET is configured with a second transport configuration indication state. The first transport configuration indication state is associated with a first resource type, and the second transport configuration indication state is associated with a second resource type. That is, a CORESET has two transport configuration indication states, each associated with a different resource type. In one embodiment, the SS set is configured as a common type, and the user equipment can receive downlink control information through the first transport configuration indication state according to the SS set configuration in the first and second resource types.

[0342] Figure 18A This is a schematic diagram illustrating a common type SS set for non-subband full-duplex and subband full-duplex symbols according to an example embodiment of this disclosure. Reference Figure 18A CORESET can be activated / configured with a first transport configuration indication state and / or a second transport configuration indication state, wherein

[0343] The non-subband full-duplex symbol is associated with the first transmission configuration indication state.

[0344] The subband full-duplex symbol is associated with the second transmission configuration indication state.

[0345] Figure 18B This is a schematic diagram illustrating resource allocation for monitoring an SS set according to an example embodiment of this disclosure. (Reference) Figure 18B When (or under certain circumstances) the monitoring of the first search space occurs simultaneously in both subband full-duplex and non-subband full-duplex symbols and / or the first SS is configured as follows: Figure 18A When the common type is shown, the user equipment can monitor the first search space in non-subband full-duplex symbols and subband full-duplex symbols through a first transmission configuration indication state or a second transmission configuration indication state (e.g., according to RRC / MAC CE / DCI), wherein the first transmission configuration indication state or the second transmission configuration indication state may be the lowest (or highest) identifier among the active transmission configuration indication states. The user equipment can then receive downlink control information in non-subband full-duplex resources and subband full-duplex resources through the first transmission configuration indication state.

[0346] In one embodiment, the first CORESET is configured with a second transport configuration indication state (i.e., a CORESET is configured with two different transport configuration indication states), and the user equipment can receive a new field configuration for determining the transport configuration indication state association. The transport configuration indication state association is the association between a specific transport configuration indication state and a specific resource type.

[0347] Figure 19 This is a schematic diagram illustrating two SS sets for non-subband full-duplex and subband full-duplex symbols according to an example embodiment of this disclosure. Reference Figure 19 When (or under certain circumstances) the monitoring search space may occur in subband full-duplex and / or non-subband full-duplex symbols,

[0348] The search space can be configured with new fields for applying at least one of the following. For example,

[0349] First transmission configuration indication state and second transmission configuration indication state: Non-subband full-duplex symbols are associated with the first transmission configuration indication state, and subband full-duplex symbols are associated with the second transmission configuration indication state;

[0350] First transmission configuration indicates status;

[0351] The second transmission configuration indication state. That is, the transmission configuration indication state association is, for example, that a non-subband full-duplex symbol is associated with the first transmission configuration indication state and a subband full-duplex symbol is associated with the second transmission configuration indication state, the first transmission configuration indication state is associated with both non-subband full-duplex symbols and subband full-duplex symbols, or the second transmission configuration indication state is associated with both non-subband full-duplex symbols and subband full-duplex symbols.

[0352] In one embodiment, when (or in some cases) this field is not configured, the user equipment may apply default rules to determine the transport configuration indication state for SS monitoring, for example, applying a first transport configuration indication state.

[0353] For example, SS set #1, such as a UE-specific SS set (or a public SS set for advanced UEs), is configured with a first transmission configuration indication state and a second transmission configuration indication state. The first transmission configuration indication state monitors the non-subband full-duplex symbols, and the second transmission configuration indication state monitors the subband full-duplex symbols. SS set #2, such as a public SS set that may be transparent to UEs without subband full-duplex capability, is configured with only a first transmission configuration indication state, and the first transmission configuration indication state monitors both non-subband full-duplex symbols and subband full-duplex symbols.

[0354] In one embodiment, when the SS set is configured to select a first transmission configuration indication state and a second transmission configuration indication state based on a new field configuration, the user equipment can receive DCI in a first resource type via the first transmission configuration indication state, and the user equipment can receive DCI in a second resource type via the second transmission configuration indication state. That is, the transmission configuration indication state association is that non-subband full-duplex symbols are associated with the first transmission configuration indication state and subband full-duplex symbols are associated with the second transmission configuration indication state. Figure 19 For example, SS set #1 is configured to select a first transmission configuration indication state and a second transmission configuration indication state. The user equipment can receive DCI in a non-subband full-duplex symbol through the first transmission configuration indication state, and the user equipment can receive DCI in a subband full-duplex symbol through the second transmission configuration indication state.

[0355] In one embodiment, when the SS set is configured to select a first transmission configuration indication state or a second transmission configuration indication state based on a new field configuration, the user equipment can receive DCI in a first resource type and a second resource type via either the first transmission configuration indication state or the second transmission configuration indication state, respectively. That is, the transmission configuration indication state association is that the first transmission configuration indication state is associated with both non-subband full-duplex symbols and subband full-duplex symbols, or the second transmission configuration indication state is associated with both non-subband full-duplex symbols and subband full-duplex symbols. Figure 19 For example, SS set #2 is configured to select the first transmission configuration indication state, and the user equipment can receive DCI in both non-subband full-duplex symbols and subband full-duplex symbols through the first transmission configuration indication state.

[0356] Figure 20 This is a schematic diagram illustrating three SS sets for non-subband full-duplex and subband full-duplex symbols according to exemplary embodiments of the present disclosure. Reference Figure 20When (or under certain circumstances) the monitoring search space may occur in subband full-duplex and / or non-subband full-duplex symbols,

[0357] The search space may be configured with a new field for applying at least one of the following. For example,

[0358] First transmission configuration indication state and second transmission configuration indication state: Non-subband full-duplex symbols are associated with the first transmission configuration indication state and subband full-duplex symbols are associated with the second transmission configuration indication state;

[0359] First transmission configuration indicates status;

[0360] The second transmission configuration indicates the status.

[0361] In one embodiment, when (or in some cases) this field is not configured, the user equipment may apply default rules to determine the transport configuration indication state for SS monitoring, for example, applying the first transport configuration indication state.

[0362] For example, SS set #1, such as a UE-specific SS set (or a common SS set for advanced UEs), is configured with a first transmission configuration indication state and a second transmission configuration indication state, monitored in non-subband full-duplex symbols via the first transmission configuration indication state and in subband full-duplex symbols via the second transmission configuration indication state. SS set #2, such as a common SS set, is configured only with the first transmission configuration indication state and is monitored in both non-subband full-duplex symbols and subband full-duplex symbols via the first transmission configuration indication state. SS set #3, such as a UE-specific SS set, is configured only with the second transmission configuration indication state and is monitored in subband full-duplex symbols via the second transmission configuration indication state, but is expected to be monitored in non-subband full-duplex symbols.

[0363] In one embodiment, when the SS set is configured to select a first transmission configuration indication state or a second transmission configuration indication state based on a new field configuration, the user equipment can receive DCI in a first resource type via the first transmission configuration indication state, or receive DCI in a second resource type via the second transmission configuration indication state, respectively. That is, the transmission configuration indication state association is that the first transmission configuration indication state is associated with both non-subband full-duplex symbols and subband full-duplex symbols, or the second transmission configuration indication state is associated with both non-subband full-duplex symbols and subband full-duplex symbols. Figure 20 For example, SS set #3 is configured to select the second transmission configuration indication state, and the user equipment can receive DCI in the second transmission configuration indication state in a subband full-duplex symbol. Alternatively, if the SS set is configured to select either the first or second transmission configuration indication state based on a new field, the user equipment may not expect to receive DCI in the second resource type or the first resource type. Figure 20 For example, SS set #3 is configured to select the second transmission configuration indication state, and the user equipment may receive DCI in a subband full-duplex symbol through the second transmission configuration indication state, and / or the user equipment may not expect to receive DCI in a non-subband full-duplex symbol.

[0364] Figure 21 This is a flowchart illustrating a set of SSs associated with one or two transport configuration indication states according to exemplary embodiments of the present disclosure. (See also:) Figure 21 To identify the association of SS sets, the user equipment can identify whether the type of the SS set associated with the control resource set is a common type (step S2110). When (or in some cases) the type of the SS set is not a common type but a UE-specific type, the user equipment can identify whether the number of transmission configuration indication states activated for the control resource set is one (step S2120). When (or in some cases) the number of transmission configuration indication states activated for the control resource set is two (i.e., determined to be "No"), one control resource set identifier, for example, 2, is associated with two transmission configuration indication states, for example, a first transmission configuration indication state and a second transmission configuration indication state, which are associated / configured with subband full-duplex symbols and non-subband full-duplex symbols, respectively. When (or in some cases) the number of transmission configuration indication states activated for the control resource set is one (i.e., determined to be "Yes"), one control resource set identifier, for example, 1, is associated with one transmission configuration indication state, for example, a first transmission configuration indication state, which is associated / configured with both subband full-duplex symbols and non-subband full-duplex symbols.

[0365] When (or in certain circumstances) the type of the SS set is a UE-specific type, the user equipment can identify whether the number of transmission configuration indication states activated for the control resource set is one (step S2130). When (or in certain circumstances) the number of transmission configuration indication states activated for the control resource set is two (i.e., determined to be "No"), one control resource set identifier, for example, 0, is associated with two transmission configuration indication states, for example, a first transmission configuration indication state and a second transmission configuration indication state, or only one transmission configuration indication state, for example, a second transmission configuration indication state, is associated / configured with both subband full-duplex symbols and non-subband full-duplex symbols. When (or in certain circumstances) the number of transmission configuration indication states activated for the control resource set is one (i.e., determined to be "Yes"), one control resource set identifier, for example, 0, is associated with one transmission configuration indication state, for example, a first transmission configuration indication state, which is associated / configured with both subband full-duplex symbols and non-subband full-duplex symbols.

[0378] In one embodiment, the user equipment may not intend to monitor the search space set in symbols that fully / partially overlap with the corresponding control resource set and uplink subband. In one embodiment, when physical downlink control channel reception includes two physical downlink control channels from two respective search space sets, the physical downlink control channel candidate that ends later in time may be used for one of the purposes of determining the time offset between downlink control information reception and the corresponding physical downlink shared channel.

(Reference) Figure 30A The transmission configuration indication state can be configured to have up to two reference signals: a first reference signal, for example, for a first QCL-typeD, and a second reference signal, for example, for a second QCL-typeD.

[0380] Figure 30B This is a schematic diagram illustrating a transmission configuration indication status indication according to an exemplary embodiment of the present disclosure. (See reference) Figure 30B When configuring a physical downlink control channel for full-duplex operation (or subband full-duplex) in certain circumstances, at least one transmission configuration indication state indicator for the physical downlink control channel may be applied. The control resource set can be activated / configured using a first transmission configuration indication state, wherein...

[0381] The "V" field indicates whether the second reference signal is presented in the corresponding control resource set. If this "V" field is set to "0", the second reference signal is not presented. If this "V" field is set to "1", the second reference signal is presented.

[0382] In one embodiment, a first transmission configuration indication state is configured with a second reference signal. The first reference signal is associated with a first resource type, and the second reference signal is associated with a second resource type. That is, a transmission configuration indication state is configured with two different reference signals, each associated with a different resource type.

[0383] In one embodiment, the search space set is configured as a user equipment-specific type. When the search space set is monitored in a first resource type, the user equipment can receive downlink control information via a first transmission configuration indication state with a first reference signal, and / or when the search space set is monitored in a second resource type, the user equipment can receive downlink control information via a first transmission configuration indication state with a second reference signal.

[0385] The non-subband full-duplex symbol is associated with the first reference signal.

[0386] The sub-band full-duplex symbol is associated with the second reference signal.

[0387] Figure 31B This is a schematic diagram illustrating resource allocation for monitoring a search space set according to exemplary embodiments of the present disclosure. (See reference) Figure 31B When (or under certain circumstances) the monitoring of the first search space occurs in both subband full-duplex and non-subband full-duplex symbols and / or the first search space is configured as a user equipment-specific type,

[0388] User equipment can monitor the first search space in non-subband full-duplex symbols by the transmission configuration indication state associated with the first reference signal, and / or

[0389] User equipment (UE) can monitor a first search space in a sub-band full-duplex symbol via a transmission configuration indication state associated with a second reference signal. Then, if a UE-specific search space set is monitored in a non-sub-band full-duplex symbol, the UE can receive downlink control information via a first transmission configuration indication state with the first reference signal, and / or if a UE-specific search space set is monitored in a sub-band full-duplex symbol, the UE can receive downlink control information via a first transmission configuration indication state with a second reference signal.

[0390] In one embodiment, a first transmission configuration indication state is configured with a second reference signal. The first reference signal is associated with a first resource type, and the second reference signal is associated with a second resource type. That is, a transmission configuration indication state is configured with two different reference signals, each associated with a different resource type. In one embodiment, the search space set is configured as a common type, and the user equipment can receive downlink control information via the first reference signal based on the search space set configuration of the first and second resource types.

[0391] Figure 32A This is a schematic diagram illustrating the association between a common type of search space set and a reference signal according to exemplary embodiments of the present disclosure. (Reference) Figure 32A The transmission configuration indication state can be activated / configured to have a first reference signal and a second reference signal, wherein

[0392] The non-subband full-duplex symbol is associated with the first reference signal.

[0393] The sub-band full-duplex symbol is associated with the second reference signal.

[0394] Figure 32B This is a schematic diagram illustrating resource allocation for monitoring a search space set according to exemplary embodiments of the present disclosure. (See reference) Figure 32B When (or under certain circumstances) monitoring of the first search space occurs in both subband full-duplex and non-subband full-duplex symbols and / or the first search space is configured as common,

[0395] User equipment can monitor the first search space in non-subband full-duplex symbols and subband full-duplex symbols by means of a transmission configuration indication state associated with the first reference signal or the second reference signal (e.g., according to RRC / MAC CE / DCI).

[0396] The first or second reference signal may be the lowest (or highest) identifier among the reference signals. The user equipment can then receive downlink control information in subband full-duplex and non-subband full-duplex symbols via the first or second reference signal.

[0397] In one embodiment, a first transmission configuration indication state is configured to have a second reference signal (i.e., a transmission configuration indication state is configured to have two different reference signals), and the user equipment can receive a new field configuration for determining the transmission configuration indication state association. The transmission configuration indication state association is an association between a specific reference signal and a specific resource type associated with a transmission configuration indication state.

[0398] In one embodiment, when the search space set is configured to simultaneously select a first reference signal and a second reference signal according to a new field configuration, the user equipment can receive downlink control information via the first reference signal in a first resource type and via the second reference signal in a second resource type.

[0399] In one embodiment, when the search space set is configured to select a first reference signal or a second reference signal according to a new field configuration, the user equipment can receive downlink control information in a first resource type and a second resource type through a first transmission configuration indication state or a second transmission configuration indication state, respectively.

[0400] In one embodiment, when the search space set is configured to select a first reference signal or a second reference signal according to a new field configuration, the user equipment may receive downlink control information in a first resource type via a first transmission configuration indication state or in a second resource type via a second transmission configuration indication state, and / or the user equipment may not expect to receive downlink control information in the second resource type or the first resource type, respectively.

[0401] Figure 33This is a schematic diagram illustrating the association between two search space sets and two reference signals according to an exemplary embodiment of the present disclosure. (Reference) Figure 33 When (or under certain circumstances) the monitoring search space may be located in subband full-duplex and / or non-subband full-duplex symbols,

[0402] The search space may be configured to have a new field for applying at least one of the following. For example,

[0403] Both the first reference signal and the reference signal:

[0404] The non-subband full-duplex symbol associated with the first reference signal,

[0405] Subband full-duplex symbol associated with the second reference signal;

[0406] First reference signal;

[0407] The second reference signal. That is, the transmission configuration indication state association is, for example, one of the non-subband full-duplex symbols associated with the first reference signal and the subband full-duplex symbols associated with the second reference signal, the first reference signal associated with the non-subband full-duplex symbols and the subband full-duplex symbols, or the second reference signal associated with the non-subband full-duplex symbols and the subband full-duplex symbols.

[0408] In one embodiment, when (or in some cases) this field is not configured, the user equipment may apply default rules to determine a reference for search space monitoring, for example, applying a first reference signal.

[0409] For example, search space set #1, such as a user equipment-specific search space set (or a common search space set for advanced user equipment), is configured with a first reference signal and a second reference signal. It is monitored via the first reference signal in non-subband full-duplex symbols and via the second reference signal in subband full-duplex symbols. The user equipment can then receive downlink control information via the first reference signal in non-subband full-duplex symbols and via the second reference signal in subband full-duplex symbols. Search space set #2, for example, may be a transparent common search space set for user equipment without subband full-duplex capability, configured only with the first reference signal and monitored via the first reference signal in both non-subband full-duplex and subband full-duplex symbols. The user equipment can then receive downlink control information via a first transmission configuration indication state or a second transmission configuration indication state in both non-subband full-duplex and subband full-duplex symbols.

[0410] Figure 34 This is a schematic diagram illustrating the association of two search space sets and three reference signals according to exemplary embodiments of the present disclosure. (Reference) Figure 34When (or under certain circumstances) the monitoring search space may occur in subband full-duplex and / or non-subband full-duplex symbols, the search space may be configured with new fields for applying at least one of the following, for example,

[0411] Both the first reference signal and the reference signal:

[0412] The non-subband full-duplex symbol associated with the first reference signal,

[0413] Subband full-duplex symbol associated with the second reference signal;

[0414] First reference signal;

[0415] Second reference signal.

[0416] In one embodiment, when (or in some cases) this field is not configured, the user equipment may apply default rules to determine a reference for search space monitoring, for example, by applying a first reference signal.

[0417] For example, search space set #1, such as a user equipment-specific search space set (or a common search space set for advanced user equipment), is configured with a first reference signal and a second reference signal, monitored via the first reference signal in non-subband full-duplex symbols and via the second reference signal in subband full-duplex symbols. Search space set #2, such as a common search space set, is configured only with the first reference signal and monitored via the first reference signal in both non-subband full-duplex symbols and subband full-duplex symbols. Search space set #3, such as a common search space set, is configured only with the second reference signal in, for example, subband full-duplex symbols, and is a search space set that the user equipment can expect to monitor in non-subband full-duplex symbols. The user equipment can then receive downlink control information in non-subband full-duplex symbols via a first transmission configuration indication state, and may not expect to receive downlink control information in subband full-duplex symbols.

Figure 35B This is a schematic diagram illustrating a reference signal associated with a sub-band full-duplex symbol according to exemplary embodiments of the present disclosure. Reference Figure 35A and Figure 35B The base station (NW) can prepare a set of reference signals for beam management, which is shared between non-subband full-duplex and subband full-duplex resources. The same set is used for non-subband full-duplex (e.g., first channel state information reporting) and / or for subband full-duplex (e.g., second channel state information reporting). For example, this set of reference signals is a combination of reference signals #A, #B, and #C.

[0419] In one embodiment, the capability of the user equipment is capability #1, and the reference signal is received via the same receive beam. Beam tracking of a transmission configuration indication / reference signal is performed by a receive beam. For both non-subband full-duplex and subband full-duplex symbols, the transmission configuration indication (reference signal) is in the first transmission configuration indication state (reference signal #A), and the receive beam is receive beam #1.

[0420] In one embodiment, the capability of the advanced user equipment is capability #2, which refers to the reference signal received via different receive beams. Beam tracking of a transmission configuration indication / reference signal is performed by multiple receive beams. For non-subband full-duplex symbols, the transmission configuration indication (reference signal) is in a first transmission configuration indication state (e.g., reference signal #A), and the receive beam is receive beam #1. For subband full-duplex symbols, the transmission configuration indication (reference signal) is in a first transmission configuration indication state (e.g., reference signal #A), and the receive beam is receive beam #2.

(See reference...) Figure 36 Depending on the capabilities of the user equipment, the user equipment can maintain up to two receive beams for a reference signal (e.g., CSI-RS) in the channel state information report, where

[0422] The first receiving beam may correspond to the downlink reference signal in the non-subband full-duplex resource, and

[0423] The second receiving beam can correspond to the downlink reference signal in the subband full-duplex resource.

[0424] In one embodiment, a first reference signal is associated with a second space receiver parameter, which in turn is associated with a first resource type, and the second space receiver parameter is associated with a second resource type. That is, one reference signal is associated with two different space receiver parameters, each associated with a different resource type. Each space receiver parameter is associated with a specific receiving beam.

[0425] In one embodiment, the search space set is configured as a user equipment-specific type, and the user equipment can receive downlink control information via a first transmission configuration indication state having a first space receiver parameter when the search space set is monitored in a first resource type, and / or the user equipment can receive downlink control information via a first transmission configuration indication state having a second space receiver parameter when the search space set is monitored in a second resource type.

(See also:) Figure 37A and Figure 37B When (or) the monitoring of the first search space occurs in both subband full-duplex symbols and non-subband full-duplex symbols,

[0428] User equipment can monitor the first search space in non-subband full-duplex symbols by having a first reference signal with receiving beam #1, and / or

[0429] User equipment (UE) can monitor a first search space in a sub-band full-duplex symbol using a first reference signal with receive beam #2. Then, UE can receive downlink control information with a first transmission configuration indication state having receive beam #1 if a UE-specific search space set is monitored in a non-sub-band full-duplex symbol, and / or UE can receive downlink control information with a first transmission configuration indication state having receive beam #2 if a UE-specific search space set is monitored in a sub-band full-duplex symbol. Alternatively, UE can receive downlink control information with receive beam #1 in a non-sub-band full-duplex symbol and with receive beam #2 in a BFD symbol if a common search space set is monitored in a sub-band full-duplex symbol.

Figure 38 Depending on the capabilities of the user equipment, the user equipment can maintain up to three receive beams for a reference signal (e.g., CSI-RS) in the CSI report, where

[0431] The first receiving beam may correspond to the downlink reference signal in the non-subband full-duplex resource, and / or

[0432] The second receive beam may correspond to the downlink reference signal in the subband full-duplex resource, and / or

[0433] The third receive beam can correspond to the downlink reference signal in the subband full-duplex resource (switching).

[0434] Figure 39 This is a schematic diagram illustrating the association of a control resource set identifier and three receive beams according to exemplary embodiments of this disclosure. Reference Figure 39When (or) monitoring the first search space occurs in both subband full-duplex and non-subband full-duplex symbols,

[0435] User equipment can monitor the first search space in non-subband full-duplex symbols by receiving beam #1. In one embodiment, when / or the quality of the report reference signal without panel switching is greater than the quality of the report reference signal with panel switching, user equipment can monitor the first search space in subband full-duplex symbols by receiving beam #2. In one embodiment, when / or the quality of the report reference signal with panel switching is greater than the quality of the report reference signal without panel switching, user equipment can monitor the first search space in subband full-duplex symbols by receiving beam #3.

[0436] In one embodiment, a first reference signal is associated with a second space receiver parameter, which in turn is associated with a first CSI reporting configuration, and the second space receiver parameter is associated with a second CSI reporting configuration. That is, one reference signal is associated with two different space receiver parameters, each associated with a different CSI reporting configuration. Each space receiver parameter is associated with a specific receive beam.

[0437] In one embodiment, the first control resource set is configured with either a first CSI report configuration or a second CSI report configuration, and the user equipment can receive downlink control information according to the search space set in the first resource type or the second resource type, respectively.

[0438] Figure 40 This is a schematic diagram illustrating the association of two CSI report configurations and two receive beams according to exemplary embodiments of this disclosure. (See reference...) Figure 40 Depending on the capabilities of the user equipment, the user equipment can maintain up to two receive beams for a reference signal (e.g., CSI-RS) in one or more CSI reports, where

[0439] The first receiving beam may correspond to the downlink reference signal in the non-subband full-duplex resource, and / or

[0440] The second receiving beam can correspond to the downlink reference signal in the subband full-duplex resource.

[0441] In one embodiment, a first receiving beam may be associated with a first CSI report configuration, and a second receiving beam may be associated with a second CSI report configuration. However, in some embodiments, the user equipment may not be aware of the relationship between the CSI report configuration and the resource type, meaning that the user equipment may not be able to determine the receiving beam used to monitor the search space set based on the resource type.

[0442] In one embodiment, a first CSI report configuration corresponding to a non-subband full-duplex resource is configured as a first time-domain offset, for example, time-domain offset #1, and a second CSI report configuration corresponding to a non-subband full-duplex resource is configured as a second time-domain offset, for example, time-domain offset #2. For example, time-domain offset #1 corresponds to the nth time slot and the (n+2m)th time slot, where n and m are positive integers. Time-domain offset #2 corresponds to the (n+m)th time slot and the (n+3m)th time slot, where n and m are positive integers.

[0443] In one embodiment, if a physical downlink control channel is configured for full-duplex operation (or subband full-duplex), at least one transmission configuration indication state can be applied to indicate the physical downlink control channel. A control resource set can be activated / configured to a first transmission configuration indication state.

[0444] In one embodiment, in option 1, the field "CSI Report ID" may indicate the receive beam associated with the CSI Report ID. For example, Figure 41 This is a schematic diagram illustrating a transmission configuration indication status indication according to exemplary embodiments of the present disclosure. (See reference) Figure 41 The first CSI report ID corresponds to the non-subband full-duplex symbol, and the second CSI report ID corresponds to the subband full-duplex symbol.

[0445] In one embodiment, if a physical downlink control channel is configured for full-duplex operation (or subband full-duplex), at least one transmission configuration indication state can be applied to indicate the physical downlink control channel. A control resource set can be activated / configured to a first transmission configuration indication state.

[0446] In one embodiment, in option 2, there is a one-bit indication for at least one transmission configuration indication status indication. For example, Figure 42 This is a schematic diagram illustrating a transmission configuration indication status indication according to exemplary embodiments of the present disclosure. (See reference) Figure 42 The "V" field is a one-bit indicator. If this "V" field is set to "0", the received beam is associated with the first CSI report. If this "V" field is set to "1", the received beam is associated with the second CSI report.

[0447] In one embodiment, in option 3, there is a bitmap for at least one transmission configuration indication status indication. For example, refer to... Figure 42 The field "V1" can be configured for non-subband full-duplex symbols, and the field "V2" can be configured for subband full-duplex symbols. If V1 = "1", the receive beam is associated with the first CSI report. If the field V2 = "1", the receive beam is associated with the second CSI report.

[0448] In one embodiment, the user equipment may receive a channel state information (CSI) report configuration, wherein this CSI report configuration is associated with a downlink (DL) reference signal and a first resource type. The user equipment may then report the CSI based on this CSI report configuration.

[0449] In one embodiment, multiple transmission timings of the downlink reference signal within the first resource type are used for CSI derivation.

[0450] Figure 43 This is a schematic diagram illustrating the association of two CSI reporting configurations and two receive beams with non-subband full-duplex and subband full-duplex symbols, according to exemplary embodiments of this disclosure. Reference Figure 43 Depending on the capabilities of the user equipment, the user equipment can maintain up to two receive beams for a reference signal (e.g., CSI-RS) in one or more CSI reports, where

[0451] The first receiving beam may correspond to the downlink reference signal in the non-subband full-duplex resource, and / or

[0452] The second receiving beam can correspond to the downlink reference signal in the subband full-duplex resource.

However, in some embodiments, the user equipment may not be aware of the relationship between the CSI report configuration and the resource type. In this case, it means that the user equipment may not be able to determine the receive beam used to monitor the search space set based on the resource type.

[0454] In one embodiment, a first CSI report configuration corresponding to a non-subband full-duplex resource is configured with a first time-domain offset, and a second CSI report configuration corresponding to a non-subband full-duplex resource is configured with a first time-domain offset.

[0455] In one embodiment, the frequency resources of the downlink reference signal that overlap with the frequency resources of the downlink subband are punctured. Figure 43 For example, in the (n+m)th time slot, the downlink subband allocated for the downlink reference signal is separated by the uplink subband.

[0456] In one embodiment, the frequency resources of the downlink reference signal are applied only within the downlink resources. Figure 43For example, in the nth time slot, the frequency resources allocated for the downlink reference signal occupy the available resources of the downlink.

[0509] Option 3: If the search space monitoring may occur in the subband full-duplex symbol, the user equipment may not monitor the search space.

[0510] In one embodiment, a first control resource set is configured to have a second transmission configuration indication state, the first transmission configuration indication state being associated with a first resource type, and the second transmission configuration indication state being associated with a second resource type. That is, a control resource set is configured with two transmission configuration indication states, each associated with a different resource type. In one embodiment, a search space set is configured as a common type, and the user equipment can receive downlink control information in both the first and second resource types based on the search space set configuration and the second transmission configuration indication state.

Reference Figure 55A The control resource set can be activated / configured to have a first transmission configuration indication state and a second transmission configuration indication state, wherein

[0512] The non-subband full-duplex symbol is associated with the first transmission configuration indication state, and / or

[0513] The sub-band full-duplex symbol is associated with the second transmission configuration indication state. For example, for advanced user equipment or legacy user equipment, the user equipment can monitor the first search space in non-sub-band full-duplex symbols and sub-band full-duplex symbols through the second transmission configuration indication state, where the second transmission configuration indication state is the default transmission configuration indication state.

[0514] Figure 55B This is a schematic diagram illustrating resource allocation for monitoring a search space set according to an example embodiment of this disclosure. (See reference...) Figure 55B When monitoring of the first search space occurs simultaneously in both subband full-duplex and non-subband full-duplex symbols and / or the first search space is configured as common, the user equipment can monitor the first search space in both non-subband full-duplex symbols and subband full-duplex symbols via a first transmission configuration indication state or a second transmission configuration indication state (e.g., according to RRC / MAC CE / DCI), wherein the first transmission configuration indication state or the second transmission configuration indication state may be the state with the lowest (or highest) identifier among the active transmission configuration indication states. For example, the user equipment monitors the search space set in both non-subband full-duplex symbols and subband full-duplex symbols via the second transmission configuration indication state. The user equipment can then receive downlink control information in both non-subband full-duplex symbols and subband full-duplex symbols via a control resource set having the second transmission configuration indication state.

[0515] Figure 56 This is a schematic diagram illustrating the association between a search space set of common types and two transmission configuration indication states for non-subband full-duplex and subband full-duplex symbols according to an example embodiment of this disclosure. Reference Figure 56 The control resource set can be activated / configured to have a first transmission configuration indication state and a second transmission configuration indication state, wherein

[0516] The non-subband full-duplex symbol is associated with the first transmission configuration indication state, and / or

[0517] Subband full-duplex symbols are associated with a second transmission configuration indication state. For example, a user equipment can monitor a first search space in non-subband full-duplex symbols and subband full-duplex symbols through a first transmission configuration indication state, such as SSB, and a second transmission configuration indication state, such as CSI-RS, wherein the transmission configuration indication state is configured with SSB as the default transmission configuration indication state.

[0518] In one embodiment, a first transmission configuration indication state is configured to have a second reference signal, the first reference signal being associated with a first resource type and the second reference signal being associated with a second resource type. That is, a transmission configuration indication state is configured to have two different reference signals, each associated with a different resource type. In one embodiment, the search space set is configured as a common type, and the user equipment can receive downlink control information in the first and second resource types via the second reference signal according to the search space set configuration.

[0519] In one embodiment, when monitoring of the first search space occurs simultaneously in both subband full-duplex and non-subband full-duplex symbols and / or the first search space is configured as a common type, the user equipment can monitor the first search space in both non-subband full-duplex symbols and subband full-duplex symbols associated with the transmission configuration indication state configured as SSB.

For example, the user equipment monitors the search space set in both non-sub-band full-duplex symbols and sub-band full-duplex symbols via the second reference signal. The user equipment can then receive downlink control information in both non-sub-band full-duplex symbols and sub-band full-duplex symbols via the second reference signal.

[0524] In one embodiment, a first reference signal is associated with a second space receiver parameter, which in turn is associated with a first resource type, and the second space receiver parameter is associated with a second resource type. That is, one reference signal is associated with two different space receiver parameters, each associated with a different resource type. Each space receiver parameter is associated with a specific receive beam. In one embodiment, when the corresponding transmission configuration indication state is configured to use a synchronization signal block (SSB) as the reference signal, the user equipment may not expect to monitor the search space set with different receive beams.

Reference Figure 60A Within a control resource set, multiple search space sets may be monitored in the same resource type with different transmission configuration indication states. For example, a common search space set within the control resource set may be monitored with a first transmission configuration indication state in both non-subband full-duplex and subband full-duplex symbols. However, a user equipment-specific search space set within the control resource set may be monitored with a second transmission configuration indication state in subband full-duplex symbols.
