Description

[Technical Field]

[0001] The present invention relates generally to a method for use by a user equipment, a method for use by a network device, and a user equipment. [Background technology]

[0002] Figure 1 is a schematic diagram illustrating static time division duplexing (TDD) and sub-band full duplexing (SBFD). Referring to Figure 1, a new time resource type, SBFD, is introduced for duplex operation. In SBFD, downlink (DL) sub-bands and uplink (UL) sub-bands are assigned to the same symbol. However, in time division duplexing (TDD), the DL band and the UL band are not assigned to the same symbol.

[0003] FIG. 2 is a schematic diagram illustrating simultaneous transmission (Tx) and reception (Rx) in a multi-panel transmission scheme. Referring to FIG. 2, for simultaneous Tx / Rx and adjacent channel interference reduction, separate antenna panels may be supported, e.g., panel 1 for UL transmission and panel 2 for DL ​​reception. However, the same beam for DL ​​reception (e.g., beam #A) may exist not only in SBFD resources but also in non-SBFD resources, resulting in performance degradation due to improper application of the beam for DL ​​reception on both SBFD and non-SBFD resources.

The UE is configured to receive and transmit signals over an air interface to one or more cells in a radio access network.

[0051] The base station NW can be configured to provide communication services according to at least one of the following radio access technologies (RAT): Worldwide Interoperability (WiMAX), Global System for Mobile Communications (GSM, often referred to as 2G), Enhanced Data Rate for GSM (EDGE) Radio Access Network (GERAN), General Packet Radio Service (GPRS), Universal Mobile Telecommunications System based on basic Wideband Code Division Multiple Access (W-CDMA) (UMTS, often referred to as 3G), High Speed ​​Packet Access (HSPA), LTE, LTE-A, eLTE (evolved LTE, e.g., LTE connected to 5GC), NR (often referred to as 5G), and / or LTE-APro. However, the scope of the present invention should not be limited to the above-mentioned protocols.

[0052] The base station NW may include, but is not limited to, a Node B (NB) such as UMTS, an Evolved Node B (eNB) such as LTE or LTE-A, a Radio Network Controller (RNC) such as UMTS, a Base Station Controller (BSC) such as GSM / GSM Enhanced Data Rates for GSM Evolution (EDGE) Radio Access Network (GERAN), a Next Generation eNB (ng-eNB) such as an Evolved Universal Terrestrial Radio Access (E-UTRA) BS connected with 5GC, a Next Generation Node B (gNB) such as a 5G Access Network (5G-AN), and other devices capable of controlling radio communications and managing radio resources within a cell. The BSNW can be connected to provide services to one or more UEs via a radio interface to the network.

[0053] A base station (BS) NW (also called a network device) is operable to provide wireless coverage to a specific geographic area using multiple cells included in the RAN. The BSNW may support the operation of cells. Each cell may be operable to serve at least one UE within its wireless coverage. Specifically, each cell (often called a serving cell) can serve one or more UEs within its wireless coverage (e.g., each cell schedules downlink (DL) and optionally uplink (UL) resources to at least one UE within its wireless coverage for DL ​​and optionally UL packet transmissions). The BSNW can communicate with one or more UEs in a wireless communication system via multiple cells. Note that in the UL case, the UE is the transmitter performing UL transmission, and the network (node) is the receiver performing UL reception. In the DL case, the UE is the receiver performing DL reception, and the network (node) is the transmitter performing DL transmission.

[0054] The base station NW may include a network node NN and one or more TRPs, such as TRP#1, TRP#2, etc.

[0055] The network node NN may be, but is not limited to, a Node B (NB) such as in LTE, an Evolved Node B (eNB) such as in LTE-A, a Radio Network Controller (RNC) such as in UMTS, a Base Station Controller (BSC) such as in GSM / GERAN, a New Radio Evolved Node B (NReNB) such as in NR, a Next Generation Node B (gNB) such as in NR, and other devices capable of controlling radio communications and managing radio resources within one or more cells.

[0056] A TRP (e.g., TRP#1 or TRP#2), which may also be considered a remote radio head (RRH), may be a transceiver based on a protocol of a 5G NR wireless communication system and / or a protocol of a 4G wireless communication system. The TRP may be communicatively connected to a network node NN. The network node NN may be connected to provide services to one or more UEs via one or more TRPs in the wireless communication system. For example, but not limited to, TRP#1 and TRP#2 may serve one UE, and TRP#2 may serve another UE.

[0057] As described above, the NR frame structure supports flexible configuration to address various next-generation (e.g., 5G) communication requirements, such as enhanced mobile broadband (eMBB), massive machine-wide communications (mMTC), and ultra-reliable low-latency communications (URLLC), while meeting the requirements of high reliability, high data rates, and low latency. The orthogonal frequency division multiplexing (OFDM) technology agreed upon by 3GPP can serve as the baseline for NR waveforms. Scalable OFDM numerology, such as adaptive subcarrier spacing, channel bandwidth, and cyclic prefix (CP), may also be used. Furthermore, two coding schemes are considered for NR: (1) low-density parity-check (LDPC) codes and (2) polarity codes. The coding scheme adaptation can be configured based on channel conditions and / or service applications.

[0058] It should be understood that the terms "system" and "network" used in the present invention are often used interchangeably. The term "and / or" in the disclosure is only a relational relationship that describes related objects, for example, A and / or B means that three types of relationship can exist, and can refer to three situations: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in the disclosure generally indicates that the related objects are in an "or" relationship.

[0059] In order to facilitate understanding of the technical solutions of the embodiments of the present invention, the following describes technical concepts related to the embodiments of the present invention.

[0060] Note that DL (e.g., Physical Downlink Control Channel, PDCCH) reception can occur in the TCI state regardless of the resource type. However, DL (e.g., PDCCH) reception may result in an inappropriate TCI state during duplex operation using SBFD resources, resulting in DL channel detection failure. Therefore, for DL ​​(e.g., PDCCH) reception in duplex operation, the TCI state for each resource type is taken into account. In addition, the spatial domain filter for monitoring the SS set is also considered.

[0061] FIG. 13 is a flowchart illustrating a method according to an exemplary embodiment of the present invention. Referring to FIG. 13, the method may be implemented by a UE. The UE receives a search space (SS) set configuration (step S1310). Specifically, an SS set corresponding to the SS set configuration is configured in a first control resource set (CORESET). The first CORESET is configured in a first transmission configuration indication (TCI) state. The first TCI state is configured with one reference reference signal (RS). Furthermore, the reference RS is associated with a spatial receiver (Rx) parameter. In one embodiment, the first CORESET is further associated with a serving cell identity (ID). For example, the serving cell ID of the base station NW, TRP#1, or TRP#2. The UE receives downlink control information (DCI) according to the SS set configuration (step S1320).

[0062] In one embodiment, the UE may receive a configuration for receiving DCI or an SS set associated with at least one of a first resource type or a second resource type. The DCI may be, for example, a PDCCH. The DL may be used for, for example, a PDCCH. In one embodiment, the received DCI or SS set is associated with the first resource type and the second resource type.

[0063] In one embodiment, the first resource type is associated with subband full duplex or DL. The first resource type may be, for example, SBFD associated with subband full duplex. However, the first resource type may also be non-SBFD, such as, for example, TDD with DL. The second resource type may be, for example, SBFD associated with subband full duplex. However, the second resource type may also be non-SBFD, such as, for example, TDD with DL.

[0064] In one embodiment, the SS set is configured in a second CORESET, the second CORESET is configured in 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, for the SS set monitored in the first resource type, the UE may receive DCI via the first CORESET in the first TCI state. For the SS set monitored in the second resource type, the UE may receive DCI via the second CORESET in the second TCI state.

[0065] In one embodiment, CORESET may be activated / configured with a new field to apply to, for example, at least one of non-SBFD symbols, SBFD symbols, or both non-SBFD and SBFD symbols. Non-SBFD symbols: The UE may monitor the SS set associated with the CORESET in non-SBFD symbols. It is possible that the UE does not intend to monitor the SS set associated with the CORESET in the SBFD symbol. SBFD Symbol: The UE may monitor the SS set associated with the CORESET in the SBFD symbol. It is possible that the UE does not intend to monitor the SS set associated with the CORESET in non-SBFD symbols. For both non-SBFD and SBFD symbols: The UE may monitor the SS set associated with the CORESET in both SBFD and non-SBFD symbols.

[0066] For example, Figure 14A is a schematic diagram showing one SS set associated with two control resource sets (CORESETs) according to one embodiment of the present invention, and Figure 14B is a schematic diagram showing resource allocation for monitoring the SS sets according to one embodiment of the present invention. Referring to Figures 14A and 14B, CORESET#1 associated with a first TCI state is configured with non-SBFD, and CORESET#2 associated with a second TCI state is configured with SBFD. The UE can then monitor the SS set in CORESET#1 in the first TCI state and monitor the SS set in CORESET#2 in the second TCI state. The UE then receives DCI in CORESET#1 associated with the first TCI state and receives DCI in CORESET#2 associated with the second TCI state.

[0067] In one embodiment, the CORESET may be activated / configured using a new field to apply at least one of the following: For example, both non-SBFD and SBFD symbols: The UE may monitor the SS set associated with the CORESET on both SBFD and non-SBFD symbols.

[0068] For example, Figure 15A is a schematic diagram showing a common-type SS set used for non-SBFD symbols and SBFD symbols according to one embodiment of the present invention, and Figure 15B is a schematic diagram showing resource allocation for monitoring the SS set according to one embodiment of the present invention. Referring to Figures 15A and 15B, one SS set ID can be associated / configured with one or more CORESETIDs. The type of the SS set is a common type, and its ID is 0. The first TCI state associated with the CORESETID is associated / configured with both SBFD symbols and non-SBFD symbols. Therefore, the UE can monitor the SS set in the same TCI state, for example, the first TCI state.

[0069] 16 is a flowchart showing SS sets associated with one or two CORESETs according to an exemplary embodiment of the present invention. Referring to FIG. 16, to identify the association of the SS sets, the UE may identify the number of CORESETs associated with the SS sets (step S1610). If one CORESET is associated with the SS set, the UE may identify the type of SS set associated with the CORESET (step S1620). If the type of the SS set is a common type, one TCI state, e.g., the first TCI state, associated with a CORESETID, e.g., 0, is associated / configured with both SBFD symbols and non-SBFD symbols. If the type of the SS set is a UE-specific type, one TCI state, e.g., the third TCI state, associated with a CORESETID, e.g., 2, is associated / configured with both SBFD symbols and non-SBFD symbols.

[0070] When two CORESETs are associated with an SS set, the UE can identify the type of the SS set associated with the CORESET (step S1630). When the type of the SS set is a common type, two TCI states, for example, the first TCI state and the second TCI state, associated with CORESETID, for example, 0 and 1, are associated / configured with non-SBFD symbols and SBFD symbols, respectively. When the type of the SS set is a UE-specific type, two TCI states, for example, the first TCI state and the second TCI state, associated with CORESETID, for example, 0 and 1, are associated / configured with non-SBFD symbols and SBFD symbols, respectively.

[0071] In one embodiment, a first CORESET is configured with a second TCI state, the first TCI state being associated with a first resource type, and the second TCI state being associated with a second resource type, i.e., one CORESET is configured with two TCI states, each associated with a different resource type.

[0072] In one embodiment, the SS set is configured with a user equipment (UE) specific type, and if the SS set is monitored in a first resource type, the UE can receive DCI via a first CORESET in a first TCI state, and if the SS set is monitored in a second resource type, the UE can receive DCI via the first CORESET in a second TCI state.

[0073] 17A is a schematic diagram illustrating a UE-specific type SS set used for non-SBFD symbols and SBFD symbols according to an exemplary embodiment of the present invention. Referring to FIG. 17A, CORESET is activated / configured in the first TCI state and / or the second TCI state, Non-SBFD symbols are associated with the first TCI state; The SBFD symbol is associated with a second TCI state.

[0074] 17B is a schematic diagram illustrating resource allocation for monitoring a set of SSs according to an exemplary embodiment of the present invention. Referring to FIG. 17B, if monitoring of the first search space occurs over both SBFD and non-SBFD symbols and / or the first SS is UE-specifically configured as shown in FIG. 17A, The UE may monitor a first search space for non-SBFD symbols according to a first TCI state; and / or The UE may monitor the first search space for SBFD symbols according to the second TCI state. And, if the UE-specific SS set is monitored in the first TCI state, the UE may receive DCI via CORESET in the first TCI state. Alternatively or additionally, if the UE-specific SS set is monitored in the second TCI state, the UE may receive DCI via CORESET in the second TCI state.

[0075] In one embodiment, a first CORESET is configured with a second TCI state, the first TCI state is associated with a first resource type, and the second TCI state is associated with a second resource type. That is, one CORESET is configured with two TCI states, each associated with a different resource type. In one embodiment, the SS sets are configured with a common type, and the UE can receive DCI in the first resource type and the second resource type according to the SS set configuration in the first TCI state.

[0076] 18A is a schematic diagram illustrating a common type SS set used for non-SBFD symbols and SBFD symbols according to an exemplary embodiment of the present invention. Referring to FIG. 18A, CORESET is activated / configured in the first TCI state and / or the second TCI state; Non-SBFD symbols are associated with the first TCI state, The SBFD symbol is associated with a second TCI state.

[0077] 18B is a schematic diagram illustrating resource allocation for monitoring an SS set according to an exemplary embodiment of the present invention. Referring to FIG. 18B, if monitoring of the first search space occurs in both SBFD symbols and non-SBFD symbols and / or if the first SS is configured with a common type as shown in FIG. 18A, the UE may monitor the first search space in the non-SBFD symbols and SBFD symbols according to a first TCI state or a second TCI state (e.g., according to RRC / MACCE / DCI), where the first TCI state or the second TCI state may have the lowest ID (or highest ID) among the activated TCI states. The UE may then receive DCI in the non-SBFD resources and SBFD resources according to the first TCI state.

[0078] In one embodiment, a first CORESET is configured with a second TCI state (i.e., one CORESET is configured with two different TCI states), and the UE may receive a new field configuration to determine the TCI state association, which is the association of a particular TCI state with a particular resource type.

[0079] 19 is a schematic diagram illustrating two SS sets used for non-SBFD and SBFD symbols according to an exemplary embodiment of the present invention. Referring to FIG. 19, where monitoring of the search space can occur for SBFD and / or non-SBFD symbols: The search space can be configured with NEW fields to apply at least one of the following, for example: Both the first and second TCI states: non-SBFD symbols associated with the first TCI state and SBFD symbols associated with the second TCI state; 1st TCI state, That is, the association of the TCI states is, for example, either a non-SBFD symbol associated with the first TCI state and an SBFD symbol associated with the second TCI state, a first TCI state associated with a non-SBFD symbol and an SBFD symbol, or a second TCI state associated with a non-SBFD symbol and an SBFD symbol. In one embodiment, if the field is not set (or if it is), the UE may apply a default rule for determining the TCI state of the SS monitoring, for example, the first TCI state.

[0080] For example, SS set #1, i.e., a UE-specific SS set (or a common SS set in the case of advanced UEs), is configured with both the first TCI state and the second TCI state and is monitored by the first TCI state in non-SBFD symbols and by the second TCI state in SBFD symbols. SS set #2, e.g., a common SS set that may be transparent to UEs without SBFD capabilities, is configured with only the first TCI state and is monitored by the first TCI state in non-SBFD symbols and SBFD symbols.

[0081] In one embodiment, when the new field configuration configures an SS set to select both the first TCI state and the second TCI state, the UE can receive DCI in the first TCI state in the first resource type, and the UE can receive DCI in the second TCI state in the second resource type. That is, the TCI state association is non-SBFD symbols associated with the first TCI state and SBFD symbols associated with the second TCI state. Taking Figure 19 as an example, when SS set #1 is configured to select both the first TCI state and the second TCI state, the UE can receive DCI in the first TCI state in the non-SBFD symbols and in the second TCI state in the SBFD symbols.

[0082] In one embodiment, when an SS set is configured to select either the first TCI state or the second TCI state according to the new field configuration, the UE can receive DCI of the first resource type and the second resource type in either the first TCI state or the second TCI state, respectively. That is, the TCI state association is the first TCI state associated with non-SBFD symbols and SBFD symbols, or the second TCI state associated with non-SBFD symbols and SBFD symbols. Taking Figure 19 as an example, SS set #2 is configured to select the first TCI state, and the UE can receive DCI in non-SBFD symbols and SBFD symbols in the first TCI state.

[0083] 20 is a schematic diagram illustrating three SS sets used for non-SBFD and SBFD symbols according to an exemplary embodiment of the present invention. Referring to FIG. 20, where monitoring of the search space can occur for SBFD and / or non-SBFD symbols: The search space can be configured with NEW fields to apply at least one of the following, for example: Both the first and second TCI states: non-SBFD symbols associated with the first TCI state and SBFD symbols associated with the second TCI state; 1st TCI state, This is the second TCI state. In one embodiment, if (or when) the field is not set, the UE may apply a default rule for determining the TCI state of the SS monitoring, for example, the first TCI state.

[0084] For example, SS set #1, i.e., a UE-specific SS set (or a common SS set in the case of an advanced UE), may be configured with both the first and second TCI states and monitored by the first TCI state in non-SBFD symbols and by the second TCI state in SBFD symbols. SS set #2, e.g., a common SS set, may be configured with only the first TCI state and monitored by the first TCI state in non-SBFD and SBFD symbols. SS set #3, e.g., a UE-specific SS set, may be configured with only the second TCI state and monitored by the second TCI state in SBFD symbols, but may be scheduled to monitor the SS set in non-SBFD symbols.

[0085] In one embodiment, when an SS set is configured to select either the first TCI state or the second TCI state according to the new field configuration, the UE can receive DCI in the first resource type according to the first TCI state or in the second resource type according to the second TCI state, respectively. That is, the TCI state association is the first TCI state associated with non-SBFD symbols and SBFD symbols, or the second TCI state associated with non-SBFD symbols and SBFD symbols. Taking FIG. 20 as an example, SS set #3 is configured to select the second TCI state, and the UE can receive DCI in the SBFD symbols according to the second TCI state. Alternatively or additionally, when an SS set is configured to select either the first TCI state or the second TCI state according to the new field configuration, the UE may not plan to receive DCI in the second resource type or the first resource type, respectively. Taking FIG. 20 as an example, SS set #3 is configured to select the second TCI state, and the UE can receive DCI according to the second TCI state in an SBFD symbol, and / or the UE may not plan to receive DCI in a non-SBFD symbol.

[0086] FIG. 21 is a flowchart showing SS sets associated with one or two TCI states according to an exemplary embodiment of the present invention. Referring to FIG. 21, to identify the association of an SS set, the UE can identify whether the type of the SS set associated with the CORESET is a common type (step S2110). If the type of the SS set is not a common type but a UE-specific type, the UE can identify whether the number of TCI states activated for the CORESET is one (step S2120). If the number of TCI states activated for the CORESET is two (i.e., the determination is "no"), one CORESETID (e.g., 2) associated with two TCI states, e.g., the first TCI state and the second TCI state, is associated / configured with SBFD symbols and non-SBFD symbols, respectively. If the number of TCI states activated for the CORESET is one (i.e., the determination is "yes"), one CORESETID (e.g., 1) associated with one TCI state, e.g., the first TCI state, is associated / configured with both SBFD symbols and non-SBFD symbols.

[0087] If the type of the SS set is a UE-specific type, the UE can identify whether the number of TCI states activated for CORESET is one (step S2130). If the number of TCI states activated for CORESET is two (i.e., the determination is "no"), one CORESETID, e.g., 0, associated with two TCI states, e.g., the first TCI state and the second TCI state, is associated / configured with both SBFD symbols and non-SBFD symbols of one TCI state, e.g., the second TCI state only. If the number of TCI states activated for CORESET is one (i.e., the determination is "yes"), one CORESETID, e.g., 0, associated with one TCI state, e.g., the first TCI state, is associated / configured with both SBFD symbols and non-SBFD symbols.

A field "V2" may indicate the functionality of at least one TCI state indicated by the i-th codepoint of the TCI field. For example, if this field "V2" is set to "0", the second TCI state is not displayed. If this field "V2" is set to "1", the second TCI state is displayed.

[0091] When a PDCCH (or SBFD) for duplex operation is configured, the CORESET may be activated / configured in the third TCI state and / or the fourth TCI state. The field "V3" may indicate the functionality of at least one TCI state indicated by the i-th codepoint of the TCI field. For example, if this field "V3" is set to "0", the third TCI state is not displayed. If this field "V3" is set to "1", the third TCI state is displayed. The field "V4" may indicate the functionality of at least one TCI state indicated by the i-th codepoint of the TCI field. For example, if this field "V4" is set to "0", the fourth TCI state is not displayed. If this field "V4" is set to "1", the fourth TCI state is displayed.

Referring to Figure 27B, in the SFN scheme, only one TRP uses DL resources. In the SBFD scheme, only one TRP supports duplex operation.

[0095] For example, Figure 28 is a schematic diagram illustrating a TCI state indication according to an exemplary embodiment of the present invention. Referring to Figure 28, if "sfnSchemePdcch" is set, CORESET may be activated / configured in the first TCI state and / or the second TCI state. If PDCCH (or SBFD) for duplex operation is configured, CORESET may be activated / configured in the third TCI state and / or the fourth TCI state. Fields "S1" and "S2" indicate DL resource types and / or SBFD resource types. For example, if field "S1" is set to "0", the first TCI state is used only for DL ​​resource types. If field "S1" is set to "1", the first TCI state is used for DL ​​and SBFD resource types. If field "S2" is set to "0", the second TCI state is used only for DL ​​resource types. If field "S2" is set to "1", the second TCI state is used for DL ​​and SBFD resource types.

[0096] For example, Figure 29A is a schematic diagram illustrating a TCI status indication according to an exemplary embodiment of the present invention. Referring to Figure 29A, field "V2" is set to "1", field "V3" is set to "0", field "V4" is set to "0", field "S1" is set to "1", and field "S2" is set to "0".

[0098] In one embodiment, the UE may not plan to monitor SS sets in symbols where the UL subband of the corresponding CORESET fully / partially overlaps. In one embodiment, if a PDCCH reception includes two PDCCHs from two search space sets each, the PDCCH candidate that ends later in time may be used as one of the purposes for determining the time offset between the reception of the DLDCI and the reception of the corresponding PDSCH. If one SS set among the linked SS sets in a PDCCH repetition is not monitored, the PDCCH candidate associated with the monitored SS may be used.

[0099] 30A is a schematic diagram illustrating an association between a TCI state and two reference RSs according to an exemplary embodiment of the present invention. Referring to FIG. 30A, a TCI state can be configured with up to two reference RSs, i.e., for example, a first reference RS in the case of a first QCL-type D and a second reference RS in the case of a second QCL-type D.

If this field "V" is set to "0", the secondary reference RS is not displayed. If this field "V" is set to "1", the secondary reference RS is displayed.

[0101] In one embodiment, a first TCI state is configured with a second Reference RS, where the first Reference RS is associated with a first resource type and the second Reference RS is associated with a second resource type, i.e., one TCI state is configured with two different Reference RSs, each associated with a different resource type.

[0102] In one embodiment, the SS set is configured with a UE-specific type, and if the SS set is monitored in a first resource type, the UE can receive DCI with a first TCI state on a first reference RS, and / or if the SS set is monitored in a second resource type, the UE can receive DCI with a first TCI state on a second reference RS.

[0104] 31B is a schematic diagram illustrating resource allocation for monitoring a set of SSs according to an exemplary embodiment of the present invention. Referring to FIG. 31B, if monitoring of the first search space occurs over both SBFD and non-SBFD symbols and / or the first SS is configured with a UE-specific type: The UE may monitor a first search space for non-SBFD symbols according to the TCI state associated with the first reference RS. The UE may monitor the first search space in the SBFD symbol according to the TCI state associated with the second reference RS, and may receive DCI according to the first TCI state on the first reference RS if the UE-specific SS set is monitored in the non-SBFD symbol, and / or may receive DCI according to the first TCI state on the second reference RS if the UE-specific SS set is monitored in the SBFD symbol.

[0105] In one embodiment, a first TCI state is configured with a second reference RS, where the first reference RS is associated with a first resource type and the second reference RS is associated with a second resource type. That is, one TCI state is configured with two different reference RSs, each associated with a different resource type. In one embodiment, the SS set is configured with a common type, and the UE can receive DCI according to the SS set configuration in the first resource type and according to the second resource type in the first reference RS.

[0106] 32A is a schematic diagram illustrating the association of a common type SS set with one reference RS according to an exemplary embodiment of the present invention. Referring to FIG. 32A, a TCI state is activated / configured in a first reference RS and a second reference RS; The non-SBFD symbols are associated with a first reference RS; The SBFD symbol is associated with a second reference RS.

[0107] 32B is a schematic diagram illustrating resource allocation for monitoring a set of SSs according to an exemplary embodiment of the present invention. Referring to FIG. 32B, when monitoring of the first search space occurs in both SBFD and non-SBFD symbols and the first SS is commonly configured: The UE may monitor the first search space for non-SBFD symbols and SBFD symbols depending on the TCI state (eg, according to RRC / MACCE / DCI) associated with the first reference RS or the second reference RS. The first reference RS or the second reference RS may be the lowest ID (or the highest ID) among the reference RSs, and the UE may receive DCI in both SBFD symbols and non-SBFD symbols via the first reference RS or the second reference RS.

[0108] In one embodiment, a first TCI state is configured with a second reference RS (i.e., one TCI state is configured with two different reference RSs), and the UE may receive a new field configuration to determine the association of the TCI state, which is an association of one TCI state with a specific reference RS associated with a specific resource type.

[0109] In one embodiment, when the SS set is configured to select both the first reference RS and the second reference RS according to the new field configuration, the UE can receive DCI via the first reference RS in the first resource type and DCI via the second reference RS in the second resource type.

[0110] In one embodiment, when the SS set is configured to select either the first reference RS or the second reference RS according to the new field configuration, the UE can receive DCI of the first resource type and the second resource type in either the first TCI state or the second TCI state, respectively.

[0111] In one embodiment, when the SS set is configured to select either the first reference RS or the second reference RS according to the new field configuration, the UE can receive DCI in the first resource type according to the first TCI state or receive DCI in the second resource type according to the second TCI state, respectively, and the UE may not plan to receive DCI in the second resource type or the first resource type, respectively.

[0112] 33 is a schematic diagram illustrating the association of two SS sets with two reference RSs according to an exemplary embodiment of the present invention. Referring to FIG. 33, where monitoring of the search space can occur on SBFD and / or non-SBFD symbols, The search space can be configured with NEW fields to apply at least one of the following, for example: Both the primary and reference RS: a non-SBFD symbol associated with the first reference RS; SBFD symbols associated with the second reference RS; 1st reference RS, The second reference RS, i.e., the association of the TCI state is, for example, any of a non-SBFD symbol associated with the first reference RS and an SBFD symbol associated with the second reference RS, a non-SBFD symbol and the first reference RS associated with the SBFD symbol, or a non-SBFD symbol and the second reference RS associated with the SBFD symbol. In one embodiment, if the field is not set, the UE may apply a default rule for determining the reference for SS monitoring, for example, the first reference RS.

[0113] For example, SS set #1, i.e., a UE-specific SS set (or a common SS set for advanced UEs), is configured with both a first reference RS and a second reference RS and is monitored by the first reference RS in non-SBFD symbols and by the second reference RS in SBFD symbols. The UE can then receive DCI on the first reference RS in non-SBFD symbols and on the second reference RS in SBFD symbols. SS set #2 (e.g., a common SS set that may be transparent to UEs without SBFD capability) is configured with only the first reference RS and is monitored by the first reference RS in non-SBFD symbols and SBFD symbols. The UE can then receive DCI in the first TCI state or the second TCI state in non-SBFD symbols and SBFD symbols, respectively.

[0114] 34 is a schematic diagram illustrating the association of two SS sets with three reference RSs according to an exemplary embodiment of the present invention. Referring to FIG. 34, if the monitoring of the search space can occur in SBFD and / or non-SBFD symbols, the search space can be configured in the NEW field to apply at least one of the following: Both the primary and reference RS: a non-SBFD symbol associated with the first reference RS; SBFD symbols associated with the second reference RS; 1st reference RS, This is the second reference RS. In one embodiment, if the field is not set, the UE may apply a default rule for determining the reference for SS monitoring, for example, apply the first reference RS.

[0115] For example, SS set #1, i.e., a UE-specific SS set (or a common SS set in the case of an advanced UE), is composed of both the first and second reference RSs and is monitored by the first reference RS in non-SBFD symbols and by the second reference RS in SBFD symbols. SS set #2 (e.g., a common SS set) is composed of only the first reference RS and is monitored by the first reference RS in non-SBFD symbols and SBFD symbols. SS set #3, e.g., a common SS set, is composed of only the second reference RS in SBFD symbols, and the UE can schedule the SS set to be monitored in non-SBFD symbols. The UE may then receive DCI due to the first TCI condition in non-SBFD symbols, but may not schedule DCI in SBFD symbols.

[0116] FIG. 35A is a schematic diagram showing one RS associated with a non-SBFD symbol according to an exemplary embodiment of the present invention, and FIG. 35B is a schematic diagram showing one RS associated with an SBFD symbol according to an exemplary embodiment of the present invention.

[0129] In one embodiment, a first Rx beam may be associated with a first CSI reporting configuration, and a second Rx beam may be associated with a second CSI reporting configuration. However, in some embodiments, the UE may not recognize the relationship between the CSI reporting configuration and the resource type.

Referring to Figure 47, the first CSI report ID corresponds to a non-SBFD symbol, and the second CSI report ID or the third CSI report ID corresponds to an SBFD symbol.

[0152] 48 is a schematic diagram illustrating separate CSI reports corresponding to separate Rx beams according to an exemplary embodiment of the present invention.

[0157] In one embodiment, at least one of the following is associated with a resource type: First Core Set, First TCI condition, or Reference RS. Additionally, the UE may schedule an SS set associated with the first CORESET to be monitored in the resource type.

[0158] In one embodiment, when (or if) a CORESET is configured / activated in the TCI state, the UE may schedule the SS set associated with the CORESET to be monitored with one of the resource types. For example, Figure 49A is a schematic diagram illustrating implicit resource type association according to one embodiment of the present invention, and Figure 49B is a schematic diagram illustrating resource allocation for monitoring the SS set according to one embodiment of the present invention. For example, with reference to Figure 49A, non-SBFD resources are determined as the default resource type.

[0159] Figure 49B is a schematic diagram illustrating resource allocation for monitoring SS sets according to an exemplary embodiment of the present invention. Referring to Figure 49B, if (or if) non-SBFD resources are determined as the default resource type for monitoring the first CORESET, the SS set may be monitored in the non-SBFD symbols of time slot n, where n is a positive integer. The SS set may not be monitored in the SBFD symbols of time slot n+m, where m is a positive integer. The SS set may be monitored in the non-SBFD symbols of time slot n+2m.

[0160] In one embodiment, if a CORESET is configured / activated in the TCI state: If the SS set is of a common type, the UE may presume that the SS set associated with the CORESET monitored on one of the resource types (eg, non-SBFD symbols) is the default resource type. If the SS set is of a UE-specific type, the UE may schedule the SS set associated with the CORESET monitored on one of the resource types (eg, SBFD symbols) as the default resource type.

[0161] In one embodiment, when a CORESET is configured / activated in a TCI state, the CORESET and / or the TCI state and / or the reference RS may be associated / configured with a resource type. The UE may schedule the SS set associated with the CORESET to be monitored in the resource type. For example, Figure 50A is a schematic diagram illustrating explicit resource type association according to an example of the present invention. Referring to Figure 50A, a first CORESET, a first TCI state, and a first reference RS are configured with SBFD resources by configuration.

[0162] Figure 50B is a schematic diagram illustrating resource allocation for monitoring SS sets according to an exemplary embodiment of the present invention. Referring to Figure 50B, when SBFD resources are configured to monitor the first CORESET, the SS set may not be monitored in non-SBFD symbols of time slot n (n is a positive integer). The SS set may be monitored in time slot n+m of SBFD symbols, where m is a positive integer. The SS set may not be monitored in non-SBFD symbols of time slot n+2m.

[0163] In one embodiment, when monitoring of an SS set is associated with a reference RS, the SS set may be monitored in a resource type corresponding to the reference RS measured in the CSI reporting configuration, and the reference RS may be associated with the resource type in the CSI reporting configuration, for example.

[0164] In one embodiment, when a CORESET is configured / activated in a TCI state and / or a reference RS, the UE may presume that a resource type, e.g., an SS set associated with the CORESET monitored in one of the non-SBFD symbols, is the default resource type. For example, Figure 51A is a schematic diagram illustrating implicit resource type association according to an example of the present invention. Referring to Figure 51A, non-SBFD resources are determined as the default resource type.

[0165] Figure 51B is a schematic diagram illustrating resource allocation for monitoring an SS set according to an exemplary embodiment of the present invention. Referring to Figure 51B, if (or when) non-SBFD resources are determined as the default resource type for monitoring the first CORESET, the SS set may be monitored in the non-SBFD symbols of time slot n, where n is a positive integer. The SS set may not be monitored in the SBFD symbols of time slot n+m, where m is a positive integer. The SS set may be monitored in the non-SBFD symbols of time slot n+2m.

[0166] In one embodiment, when a CORESET is configured / activated in the TCI state and / or reference RS: If the SS set is of a common type, the UE may schedule the SS set associated with the CORESET monitored on one of the resource types, eg, non-SBFD symbols, as the default resource type. If the SS set is of a UE-specific type, the UE may schedule the SS set associated with a resource type, for example, CORESET, monitored in one of the SBFD symbols as the default resource type.

[0167] In one embodiment, when (or if) a CORESET is configured / activated with a TCI state and / or a reference RS, the UE may schedule the SS set associated with the CORESET to be monitored in a resource type. In this case, the CORESET and / or the TCI state and / or the reference RS may be associated / configured with a resource type. For example, Figure 52A is a schematic diagram illustrating explicit resource type association according to an example of the present invention. Referring to Figure 52A, a first CORESET, a first TCI state, and a first reference RS are configured with SBFD resources by configuration.

[0168] Figure 52B is a schematic diagram illustrating resource allocation for monitoring SS sets according to an exemplary embodiment of the present invention. Referring to Figure 52B, when SBFD resources are configured to monitor the first CORESET, the SS set may not be monitored in non-SBFD symbols of time slot n, where n is a positive integer. The SS set may be monitored in time slot n+m of SBFD symbols, where m is a positive integer. The SS set may not be monitored in non-SBFD symbols of time slot n+2m.

[0169] Figure 53A is a schematic diagram illustrating the association of a common type SS set with one TCI state according to one embodiment of the present invention, and Figure 53B is a schematic diagram illustrating resource allocation for monitoring the SS set according to one embodiment of the present invention. With reference to Figures 53A and 53B, a CORESET may be activated / configured in the first TCI state and / or the second TCI state. If a CORESET is CORESET zero and the corresponding SS set is of a common type: Option 1 shown on the left side of Figure 53B: The UE may not expect the search space to be monitored with SBFD symbols (i.e., implementation by gNB).
