Description

Technical Field

[0001] This invention relates to a method for using user equipment, a method for using network devices, and user equipment. Background Technology

[0002] Figure 1 This is a schematic diagram illustrating Static Time Division Duplex (TDD) and Subband Full Duplex (SBFD). (Reference) Figure 1 In time-division duplex operation, a new type of time resource is introduced: subband full-duplex. In subband full-duplex, downlink and uplink subbands are allocated within the same symbol. However, in time-division duplex, downlink and uplink frequency bands are not allocated within 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 enable simultaneous transmission / reception and reduce interference between adjacent channels, separate antenna panels can be supported. For example, panel 1 can be used for uplink transmission, and panel 2 for downlink reception. However, the same beam used for downlink reception (e.g., beam #A) may exist not only in subband full-duplex resources but also in non-subband full-duplex resources, leading to performance degradation due to inappropriate beaming application for downlink reception in both subband and non-subband full-duplex resources.

[0284] The embodiments disclosed herein can be applied to unlicensed frequency bands, licensed frequency bands, non-DRX mode, DRX mode, or power-saving mode, but are not limited thereto.

[0285] In one example,

[0286] User equipment can communicate with a gNB (or network) using a carrier aggregation (CA) system. In this case, the user equipment can be configured with multiple serving cells.

[0287] User equipment can receive the physical downlink shared channel (or transmit the PUSCH) on the serving cell A of the gNB based on the downlink control information received in the serving cell B of the gNB.

[0288] User equipment can receive physical downlink shared channel (or transmit PUSCH) on the serving cell of gNB according to downlink control information, where the downlink control information may indicate a priority index.

[0293] User equipment can be configured with respect to the repetition of the physical downlink control channel used for receiving / monitoring downlink control information, wherein each repetition of the downlink control information may be transmitted by different time domain resources, frequency domain resources, or transmission configuration indications.

[0297] Figure 3A This is a schematic diagram illustrating the monitoring of the search space set used for receiving downlink control information. (Reference) Figure 3A User equipment can monitor and search a space set to receive downlink control information based on the transmission configuration indication status associated with the corresponding control resource set. For example, the downlink control information is associated with a search space set identifier / identifier, where the search space set is associated with time-domain related parameters. The search space set identifier / identifier can be further associated with a control resource set identifier / identifier, where the control resource set is associated with frequency-domain related parameters. Furthermore, the control resource set identifier / identifier can be further associated with a transmission configuration indication status identifier / identifier, where the transmission configuration indication status is associated with space-domain related parameters.

[0298] Figure 3B This is a diagram illustrating the Transmission Configuration Indicator (TCI) status within the Media Access Control (MAC) control element (CE). (See reference) Figure 3B In the Transmission Configuration Indication status indication, a search space set (identifier / identifier) ​​can be associated with a control resource set (identifier / identifier). A control resource set can be initiated with a Transmission Configuration Indication status.

[0299] Figure 4A This is a diagram illustrating the common type search space set. (See reference) Figure 4AThe search space set used for the physical downlink control channel can be a common type monitored by a set of user equipment, such as control resource set zero containing system information.

[0300] Figure 4B This is a schematic diagram illustrating a specific search space set for a user device. (Reference) Figure 4B The search space set used for the physical downlink control channel can be of a user equipment specific type monitored by a single user equipment, such as for downlink / uplink scheduling.

[0301] Figure 5A This is a schematic diagram illustrating downlink (DL) scheduling on a non-Unified Transport Configuration Indicator (TCI) framework. (Reference) Figure 5A If the scheduling offset between the scheduled downlink control information and the scheduled physical downlink shared channel is greater than or equal to a threshold, such as during the duration of decoding the downlink control information, the user equipment may assume a quasi-co-bit assumption of the physical downlink shared channel indicated by the transmission configuration indication field in the scheduled downlink control information.

[0302] Figure 5B This is a diagram illustrating the code points in the transmission configuration indication field. (Reference) Figure 5B In the transmission configuration indication field of downlink control information, the code point indicates the transmission configuration indication status identifier / identifier. For example, the code point "0" indicates transmission configuration indication status identifier / identifier 0.

[0303] Figure 6A This is a schematic diagram illustrating the two transmission configuration indication states used for downlink reception, and Figure 6B This is a schematic diagram illustrating the allocation of control resource set (CORESET) resources for a physical downlink shared channel with a transmission configuration indication field. (Reference) Figure 6A and Figure 6B There may be two control resource sets associated with two separate transport configuration indication states. If the scheduling offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume that the quasi-co-occurrence assumption of the physical downlink shared channel used for the control resource set is associated with the monitored search space that has the lowest control resource set identifier / identifier in the most recent time slot. For example, the lowest control resource set identifier / identifier is "#0".

[0304] Figure 7A This is a schematic diagram illustrating the two transmission configuration indication states used for downlink reception, and Figure 7B This is a schematic diagram illustrating the allocation of control resource sets for physical downlink shared channels without a transmission configuration indication field. (Reference) Figure 7A and Figure 7BThere may be two control resource sets associated with two separate transport configuration indication states. If the scheduling offset between the scheduled downlink control information and the scheduled physical downlink shared channel is greater than or equal to a threshold, and if the downlink control information does not contain a transport configuration indication field, the user equipment may assume that the quasi-co-occurrence assumption of the physical downlink shared channel used for the control resource set is associated with the monitored search space that has the lowest control resource set identifier / identifier in the most recent time slot. For example, the lowest control resource set identifier / identifier is "#0".

[0305] Figure 8 This is a schematic diagram illustrating the framework for downlink (DL) scheduling transmission configuration indication. (Reference) Figure 8 When a user equipment transmits the last symbol of a PUCCH containing downlink control information that corresponds to a transmission configuration indication state indication without downlink allocation, or HARQ-ACK information for a physical downlink shared channel scheduled by downlink control information carrying a transmission configuration indication state indication, and if the indicated transmission configuration indication state differs from a previous indication, the indication of the transmission configuration indication state with a transmission configuration indication state identifier / identifier may be applied from the first time slot, which may be at least a symbol after the last symbol of the PUCCH (e.g., the time of beam application). For example, if the transmission configuration indication field of downlink control information #1 indicates transmission configuration indication state #y, transmission configuration indication state #y will be applied after beam application using transmission configuration indication state #x.

[0306] Figure 9A This is a diagram illustrating resource allocation in Time Division Duplex (TDD). (Reference) Figure 9A In time-division duplex, time domain resources may be split between the downlink and uplink, which may lead to increased uplink latency.

[0307] Figure 9B This is a diagram illustrating resource allocation in Subband Full-Duplex (SBFD). (Reference) Figure 9B In sub-band full-duplex, the feasibility of allowing downlink and uplink to coexist is permitted. Sub-bands do not overlap with full-duplex on the gNB side within traditional time-division duplex frequency bands.

[0308] Figure 9C This is a schematic diagram illustrating beam management with non-subband full-duplex symbols, and Figure 9D This is a schematic diagram illustrating beam management using sub-band full-duplex symbols. (Reference) Figure 9C and Figure 9D The network may prepare two sets of reference signals for beam management, for example,

[0309] A set of functions for non-subband full-duplex, such as the first channel state information report;

[0310] Another set is used for sub-band full-duplex, for example, second channel status information reporting.

[0311] Figure 10 This is a schematic diagram illustrating the scheduling downlink control information used to determine time and frequency resources. (Reference) Figure 10 Regardless of resource type, a preset transmission configuration indication state is configured for potential physical downlink shared channel (PHS) reception. This is used when scheduling downlink control information is used to determine time and / or frequency resources. A preset transmission configuration indication state used for controlling the reception of non-subband full-duplex symbols may be used for potential PHS shared channel reception in subband full-duplex symbols, leading to performance degradation or a reduction in PHS shared channels scheduled with inappropriate preset transmission configuration indication states. Therefore, for downlink (e.g., physical downlink control channel) reception over duplex operation, the transmission configuration indication state for each resource type will be considered. The preset transmission configuration indication state determination for PHS shared channel reception over both non-uniform and uniform transmission configuration indication frameworks will be considered.

[0312] Figure 11 This is a schematic diagram illustrating a wireless communication network architecture 1 according to an exemplary embodiment of this disclosure. (See reference...) Figure 11 A wireless communication network architecture 1 (e.g., a Long Term Evolution (LTE) system, an LTE-A system, an LTE-Pro 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 components that provide connectivity to the network. The UE communicates with the network (e.g., a core network (CN), an evolved packet core (EPC) network, an evolved shared terrestrial radio access network (E-UTRAN), a 5G core (5GC), or the Internet) through the radio access network established by one or more base stations.

[0313] 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, including but not limited to mobile phones, tablet computers, 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.

[0314] The base station NW can be configured to provide communication services based on 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 (EDGE) Radio Access Network (GERAN), Shared Packet Radio Service (GPRS), Shared Mobile Communications System (UMTS, commonly referred to as 3G) based on Basic Wideband Code Division Multiple Access (W-CDMA), High-Speed ​​Packet Access (HSPA), LTE, LTE-A, eLTE (evolved LTE, such as LTE connected to 5GC), NR (commonly referred to as 5G), and / or LTE-APro. However, the scope of this disclosure should not be limited to the protocols mentioned above.

[0315] 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 Evolution (EDGE) Radio Access Network (GERAN), a next-generation eNB (ng-eNB) in an Evolved Shared Terrestrial Radio Access (E-UTRA) base station connected to a 5GC, a next-generation Node B (gNB) in a 5G Access Network (5G-AN), and any other device capable of controlling wireless communications and managing radio resources within the cell. A base station NW can connect to the network via a wireless interface to serve one or more user equipment.

[0316] A base station (BS) NW (or network device) is operable to provide radio coverage to a specific geographic area using multiple cells included in a radio access network. The base station NW supports cell operation. Each cell is operable 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) provides service to one or more UEs within its radio coverage area (e.g., each cell schedules downlink (DL) and optional uplink (UL) resources for downlink and optional uplink packet transmissions for at least one UE within its radio coverage area). The base station NW can communicate with one or more UEs in a wireless communication system through multiple cells. It should be noted that, for uplink, the UE is the transmitter performing uplink transmission, and the network (node) is the receiver performing uplink reception. For downlink, the UE is the receiver performing downlink reception, and the network (node) is the transmitter performing downlink transmission.

[0317] A base station NW may include a network node NN and one or more TRPs, such as TRP#1 and TRP#2.

[0318] The network node NN can 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 Evolved 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.

[0319] A Transceiver Point (TRP) (e.g., TRP#1 or TRP#2), also considered a Remote Radio Head (RRH), may be a transceiver under 5G NR and / or 4G wireless communication system protocols. A TRP can communicatively connect to a Network Node (NN). A NN can connect in a wireless communication system through one or more TRPs to serve one or more User Equipments (UEs). For example, TRP#1 and TRP#2 serve one UE, while TRP#2 serves another UE, but this is not a limitation.

[0320] As described 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 can serve as the basis for the NR waveform. Scalable OFDM digital systems, 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 can be configured according to channel conditions and / or service applications.

[0321] 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. Furthermore, the character " / " in this disclosure generally indicates that the related objects are in an "or" relationship.

[0322] To facilitate understanding of the technical solutions of the embodiments disclosed herein, the technical concepts related to the embodiments disclosed herein are described below.

[0323] Figure 12 This is a flowchart illustrating an exemplary embodiment of a method according to this disclosure. (See reference...) Figure 12This method can be implemented by a user equipment. The user equipment receives downlink information configuration (step S1210). Specifically, the downlink information configuration is associated with time-domain and frequency-domain information of the received downlink information. The time-domain information may indicate resource allocation in the time domain. The frequency-domain information may indicate resource allocation in the frequency domain. In one embodiment, the downlink information configuration may be further associated with spatial-domain information of the received downlink information. The spatial-domain information may indicate resource allocation in the spatial domain.

[0324] The user equipment receives downlink information for scheduling the Physical Downlink Shared Channel (PDSCH) (step S1220). The downlink information may be, for example, a control resource set identifier / identifier, a search space set identifier / identifier, a transmission configuration indication status identifier / identifier, a reference reference signal identifier / identifier, and / or spatial reception parameters. The user equipment can configure its downlink reception based on the downlink information.

[0325] The user equipment receives the physical downlink shared channel based on the downlink information and the first transmission configuration indication state (step S1230). Specifically, the first transmission configuration indication state includes one or more parameters for configuring the relationship between the downlink reference signal and one or more demodulation reference signal ports of the physical downlink shared channel.

[0326] In one embodiment, the user equipment may receive configuration to configure downlink information to be received in at least one of the following resource types: a first resource type or a second resource type.

[0327] In one embodiment, the received downlink information is associated with a first resource type and a second resource type (both).

[0328] In one embodiment, the time offset between downlink information and the physical downlink shared channel is less than a threshold. The time unit for the time offset can be a time slot, a symbol, or another time unit.

[0329] In one embodiment, the user equipment may assume that the quasi-co-location assumption for the control resource set is associated with the monitored search space that has the lowest control resource set identifier / identifier in the latest time slot.

[0330] In one embodiment, the latest timeslot is associated with the same resource type as the timeslot used to receive the physical downlink shared channel.

[0331] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume a quasi-co-location assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest time slot, wherein the latest time slot may be associated with a subband full-duplex / non-subband full-duplex symbol respectively.

[0332] For example, Figure 13A This is a schematic diagram illustrating the relationship between control resource sets and resource types, according to an example embodiment of this disclosure. (See reference...) Figure 13A The control resource set #1 associated with the first transmission configuration indication state is configured as a non-subband full-duplex resource, while the control resource set #2 associated with the second transmission configuration indication state is configured as a subband full-duplex resource. Figure 13B This is a schematic diagram illustrating the allocation of resources in a control resource set, based on an example embodiment of this disclosure. (See reference...) Figure 13B If the time offset between the downlink control information scheduled by control resource set #1 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume the quasi-co-location assumption for control resource set #1 in the latest time slot.

[0333] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume a quasi-co-position assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest timeslot, wherein the lowest control resource set identifier / identifier is selected from the control resource set associated with the same resource type as the scheduled physical downlink shared channel and / or from the control resource set associated with both resource types, and / or the latest timeslot is selected from the timeslot associated with the control resource set associated with the same resource type as the scheduled physical downlink shared channel and / or from the timeslot associated with the control resource set associated with both resource types.

[0334] For example, Figure 14A This is a schematic diagram illustrating the relationship between control resource sets and resource types, according to an example embodiment of this disclosure. (See also...) Figure 14A The control resource set #1 associated with the first transmission configuration indication state is configured as a non-subband full-duplex resource, while the control resource set #3 associated with the third transmission configuration indication state is configured as a subband full-duplex resource and a non-subband full-duplex resource. Figure 14B This is a schematic diagram illustrating the allocation of resources in a control resource set, according to an example embodiment disclosed herein. (See reference...) Figure 14B If the time offset between the downlink control information scheduled by control resource set #1 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume the quasi-co-location assumption for control resource set #1 in the latest time slot.

[0335] In one embodiment, the minimum control resource set identifier / identifier is selected from at least one control resource set associated with the same resource type as the time slot for receiving the physical downlink shared channel.

[0336] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume a quasi-co-position assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest time slot, wherein the lowest control resource set identifier / identifier is selected from the control resource set associated with the same resource type as the scheduled physical downlink shared channel and / or the control resource set associated with both resource types.

[0337] For example, Figure 15A This is a schematic diagram illustrating the relationship between control resource sets and resource types, according to an example embodiment of this disclosure. (See also...) Figure 15A The control resource set #3 associated with the third transmission configuration indication state is configured as sub-band full-duplex resource and non-sub-band full-duplex resource. Figure 15B This is a schematic diagram illustrating the allocation of resources in a control resource set, according to an example embodiment disclosed herein. (See reference...) Figure 15B If the time offset between the downlink control information scheduled by control resource set #3 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume the quasi-co-location assumption for control resource set #3 in the latest time slot.

[0338] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume a quasi-co-position assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest time slot, wherein the lowest control resource set identifier / identifier is selected from the control resource set associated with the same resource type as the scheduled physical downlink shared channel and / or the control resource set associated with two resource types.

[0339] For example, Figure 16A This is a schematic diagram illustrating the relationship between control resource sets and resource types, according to an example embodiment of this disclosure. (See also...) Figure 16A The control resource set #1 associated with the first transmission configuration indication state is configured as a non-subband full-duplex resource, while the control resource set #3 associated with the third transmission configuration indication state is configured as a subband full-duplex resource and a non-subband full-duplex resource. Figure 16B This is a schematic diagram illustrating the allocation of resources in a control resource set, according to an example embodiment disclosed herein. (See reference...) Figure 16B If the time offset between the downlink control information scheduled by control resource set #3 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume a quasi-co-location assumption for control resource set #3 with two resource types.

[0340] In one embodiment, at least one control resource set is configured with a group index value, and / or the group index value is associated with a resource type.

[0341] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume a quasi-co-position assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest timeslot, wherein the lowest control resource set identifier / identifier is selected from control resource sets associated with the same resource type as the scheduled physical downlink shared channel and / or control resource sets associated with two resource types. The control resource set may be configured with a control resource set pool index value, for example via RRC, wherein the control resource set pool index value may be associated with a resource type.

[0342] For example, Figure 17A This is a schematic diagram illustrating the relationship between control resource sets and resource types, according to an example embodiment of this disclosure. (See also...) Figure 17A There are control resource sets #1 associated with a first transmission configuration indication state, control resource sets #2 associated with a second transmission configuration indication state, and control resource sets #3 associated with a third transmission configuration indication state. These control resource sets are configured with a control resource set pool index 0 associated with non-subband full-duplex resources. There are also control resource sets #3 associated with a third transmission configuration indication state, control resource sets #4 associated with a fourth transmission configuration indication state, and control resource sets #5 associated with a fifth transmission configuration indication state. These control resource sets are configured with a control resource set pool index 1 associated with subband full-duplex resources.

[0343] Figure 17B This is a schematic diagram illustrating the allocation of resources in a control resource set, according to an example embodiment disclosed herein. (See reference...) Figure 17B If the time offset between the downlink control information scheduled by control resource set #3 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume the quasi-co-location assumption used by control resource set #3 associated with the subband full-duplex resource in the latest time slot.

[0344] In one embodiment, the user equipment may assume a quasi-co-bit assumption with the lowest control resource set identifier / identifier among multiple control resource sets configured with group index values ​​associated with the same type of time slot as the received physical downlink shared channel.

[0345] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume, respectively, the use of a quasi-co-bit assumption with the lowest control resource set identifier / identifier in the control resource set configured with the control resource set pool index value associated with the subband full-duplex / non-subband full-duplex symbol.

[0346] For example, Figure 18 This is a schematic diagram illustrating the relationship between control resource sets and resource types, and their resource allocation, according to an example embodiment disclosed herein. (See reference...) Figure 18 There are control resource sets #1 associated with a first transmission configuration indication state and #2 associated with a second transmission configuration indication state, which are configured with a control resource set pool index 0 associated with non-subband full-duplex resources. There are also control resource sets #3 associated with a third transmission configuration indication state and #4 associated with a fourth transmission configuration indication state, which are configured with a control resource set pool index 1 associated with subband full-duplex resources. If the time offset between the downlink control information scheduled by control resource set #1 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume the quasi-co-bit assumption used by control resource set #1, which is configured with a control resource set pool index 0 associated with non-subband full-duplex resources.

[0347] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a sub-band full-duplex / non-sub-band full-duplex symbol, the user equipment may assume, respectively, the use of a quasi-co-bit assumption with the lowest control resource set identifier / identifier in a control resource set configured with control resource set pool index values ​​associated with sub-band full-duplex / non-sub-band full-duplex symbols. A control resource set may be configured with one or two control resource set pool index values.

[0348] For example, Figure 19 This is a schematic diagram illustrating the relationship between control resource sets and resource types, and their resource allocation, according to an example embodiment disclosed herein. (See reference...) Figure 19There are control resource sets #1 associated with a first transmission configuration indication state, #2 associated with a second transmission configuration indication state, and #0 associated with a zeroth transmission configuration indication state. These control resource sets are configured with a control resource set pool index 0 associated with non-subband full-duplex resources. There are also control resource sets #3 associated with a third transmission configuration indication state, #4 associated with a fourth transmission configuration indication state, and #0 associated with a zeroth transmission configuration indication state. These control resource sets are configured with a control resource set pool index 1 associated with subband full-duplex resources. If the time offset between the downlink control information scheduled by control resource set #1 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume the quasi-co-bit assumption used by control resource set #1, which is configured with control resource set pool index 0 associated with non-subband full-duplex resources.

[0349] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume, respectively, the use of a quasi-co-bit assumption with the lowest control resource set identifier / identifier in the control resource set configured with the control resource set pool index value associated with the subband full-duplex / non-subband full-duplex symbol.

[0350] Option 1: A control resource set can be configured with one or two control resource set pool index values.

[0351] Option 2: When a control resource set is not configured with any control resource set pool index value, the control resource set may be associated with a control resource set pool index value (e.g., the first, second, or third control resource set pool index value).

[0352] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume a quasi-co-position assumption with the lowest control resource set identifier / identifier in the control resource set associated with the subband full-duplex / non-subband full-duplex symbol, respectively.

[0353] Option 3: When a control resource set is not configured with any control resource set pool index value, the control resource set can be associated with subband full-duplex and non-subband full-duplex.

[0354] In one embodiment, the user equipment may assume a quasi-co-location assumption for the control resource set associated with the monitored search space, which has the lowest control resource set identifier / identifier in the latest time slot and is located among multiple control resource sets associated with a common type of the search space set.

[0355] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume a quasi-co-occurrence assumption for the control resource set associated with the monitored search space, which has the lowest control resource set identifier / identifier in the latest timeslot and is located among the control resource sets associated with the common type of the search space set. In one embodiment, when the monitored search space set is associated with a control resource set, the user equipment may apply a transmission configuration indication state as a preset quasi-co-occurrence assumption for physical downlink shared channel reception.

[0356] For example, Figure 20A This is a schematic diagram illustrating a preset transmission configuration indication state determination considering the search space set type according to an exemplary embodiment of this disclosure. (Reference) Figure 20A The first transmission configuration indication state associated with control resource set 0, which is associated with the common search space set, is configured with sub-band full-duplex symbols and non-sub-band full-duplex symbols. The first state associated with control resource set 0, which is associated with the user equipment-specific search space set, is configured with only non-sub-band full-duplex symbols, while the second state associated with control resource set 1, which is associated with the user equipment-specific search space set, is configured with only sub-band full-duplex symbols.

[0357] Figure 20B This is a schematic diagram illustrating the allocation of control resource sets according to an exemplary embodiment of this disclosure. (Reference) Figure 20B If the time offset between the scheduled downlink control information of the search space set 1 with the user equipment specific type and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume a quasi-co-location assumption for the control resource set 0 associated with the search space set 0.

[0358] In one embodiment, the user equipment may assume a quasi-co-location assumption for the control resource set associated with the monitored search space, which has the lowest control resource set identifier / identifier in the latest timeslot and is located among multiple control resource sets associated with a common type of the search space set. When there are multiple common search space sets in the latest timeslot, the control resource set with the highest priority is determined according to a first priority rule. In one embodiment, the order of the first priority rule is predefined as descending order: a first type of physical downlink control channel associated with system information; and a second type of physical downlink control channel not associated with system information.

[0359] In one embodiment, the user equipment may assume a quasi-co-location assumption for the control resource set associated with the monitored search space, which has the lowest control resource set identifier / identifier in the latest time slot and is located among multiple control resource sets associated with a common type of the search space sets. When multiple search space sets have the same highest priority according to a first priority rule, the user equipment may determine the control resource set associated with the lowest search space set identifier / identifier among the multiple search space sets with the same highest priority.

[0360] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, and this physical downlink shared channel is scheduled in a subband full-duplex / non-subband full-duplex symbol, the user equipment may assume a quasi-co-occurrence assumption for this control resource set in the control resource set associated with the common type of the search space set in the latest time slot. In one embodiment, when there are multiple common search space sets in the latest time slot, the user equipment may determine the control resource set with the highest priority according to a first priority rule, wherein the order of the first priority rule can be predefined / fixed / configured in the following descending order:

[0361] Type 0 - Physical downlink control channel;

[0362] Type 0A - Physical Downlink Control Channel;

[0363] Type 1 - Physical Downlink Control Channel;

[0364] Type 2 - Physical Downlink Control Channel;

[0365] Type 3 - Physical Downlink Control Channel.

[0366] In one embodiment, when multiple search space sets have the same highest priority according to a first priority rule, the user equipment may determine the control resource set associated with the lowest search space set identifier / identifier among the multiple search space sets with the same highest priority.

[0367] For example, Figure 21 This is a schematic diagram illustrating the determination of a preset transport configuration indication state considering the search space set type according to an example embodiment of this disclosure. (See reference...) Figure 21The first transmission configuration indication state associated with control resource set 0, which is associated with a shared search space set configured with type 0 physical downlink control channels, is configured with sub-band full-duplex symbols and non-sub-band full-duplex symbols. The first state associated with control resource set 0, which is associated with a user equipment-specific search space set configured with type 3 physical downlink control channels, is configured with only non-sub-band full-duplex symbols, while the second state associated with control resource set 1, which is associated with a user equipment-specific search space set configured with type 3 physical downlink control channels, is configured with only sub-band full-duplex symbols. If the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume a quasi-co-position assumption in the latest timeslot for control resource set 0 associated with shared type 0 physical downlink control channels.

[0368] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in subband full-duplex / non-subband full-duplex symbols, the user equipment may assume a quasi-co-position assumption for the control resource set associated with the monitoring search space having the lowest control resource set identifier / identifier in the latest timeslot, wherein the latest timeslot may be associated with subband full-duplex / non-subband full-duplex symbols respectively.

[0369] For example, Figure 22A This is a schematic diagram illustrating the determination of a preset transport configuration indication state considering the search space set type according to an example embodiment of this disclosure. (See reference...) Figure 22A The third state associated with the control resource set 2, which is associated with the user equipment-specific search space set, is configured with only non-subband full-duplex symbols, while the fourth state associated with the control resource set 4, which is associated with the user equipment-specific search space set, is configured with only subband full-duplex symbols. Figure 22B This is a schematic diagram illustrating the allocation of resources in a control resource set according to an example embodiment of this disclosure. (See reference...) Figure 22B If the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume a quasi-co-location assumption for the control resource set 2 associated with the user equipment-specific search space set 2 in the latest timeslot.

[0370] Figure 23 This is a flowchart illustrating a method for applying a transmission configuration indication state having a control resource set according to an example embodiment of this disclosure. (See also:) Figure 23The User Equipment (UE) determines whether there are any monitored search space sets in the latest timeslot (step S2310). If there are one or more monitored search space sets in the latest timeslot, the UE determines whether at least one search space set in the monitored search space sets is configured as a common type (step S2320). If there are no search space sets configured as common types in the monitored search space sets in the latest timeslot (e.g., only search space sets configured as UE-specific), the UE determines whether the resource type of the latest timeslot is the same as the resource type received by the Physical Downlink Shared Channel (step S2330). If the latest timeslot is the same as the resource type received by the Physical Downlink Shared Channel, the UE may apply the transmission configuration indication state associated with the lowest control resource set identifier / identifier in the latest timeslot (step S2340). If the latest timeslot is different from the resource type received by the Physical Downlink Shared Channel, the UE may determine the timeslot before the latest timeslot as the new latest timeslot (step S2350) and return to step S2310. Furthermore, if there is no monitored search space set in the latest time slot, the user equipment can determine the time slot before the latest time slot as the new latest time slot (step S2350) and return to step S2310.

[0371] However, if one or more search space sets are configured as common type in the latest time slot, the user equipment determines whether multiple control resource sets are associated with the common search space set in the latest time slot (step S2360). If multiple control resource sets are associated with the common search space set in the latest time slot, the user equipment may determine one control resource set from the multiple control resource sets according to a priority rule, such as a first priority rule (step S2370). Then, the user equipment applies a transmission configuration indication state for the control resource set associated with the monitored common search space set in the latest time slot (step 2380). If only one control resource set is associated with the common search space set in the latest time slot, the user equipment applies a transmission configuration indication state for the control resource set associated with the monitored common search space set in the latest time slot (step 2380).

[0372] In one embodiment, when (if or under certain circumstances) the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in subband full-duplex / non-subband full-duplex symbols:

[0373] Option 1: The user equipment may assume a quasi-co-location assumption for the control resource set associated with the monitored search space, which has the lowest control resource set identifier / identifier among the control resource sets associated with the common type of search space set in the latest time slot.

[0374] In one embodiment, when the monitored search space set is associated with a control resource set (if or under certain circumstances), the user equipment may apply the transport configuration indication state as a preset quasi-co-location assumption for physical downlink shared channel reception.

[0375] In one embodiment, when (if or under certain circumstances) the reference signal in the transmission configuration indication state is configured to initiate a non-subband full-duplex resource type in the minimum control resource set, at least one search space set associated with the minimum control resource set may be common.

[0376] Option 2: The user equipment may assume a quasi-co-location assumption for the minimum set of control resources associated with the monitored search space.

[0377] In one embodiment, when the monitored search space set is associated with a control resource set (if or under certain circumstances), the user equipment may apply the transport configuration indication state as a preset quasi-co-location assumption for physical downlink shared channel reception.

[0378] In one embodiment, when the monitored search space set is associated with two control resource sets (if or under certain circumstances), the user equipment may apply the transmission configuration indication state associated with subband full-duplex / non-subband full-duplex symbols as a preset quasi-co-position assumption for physical downlink shared channel reception.

[0379] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in subband full-duplex / non-subband full-duplex symbols, the user equipment may assume a quasi-co-occurrence assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest time slot. In one embodiment, when the monitored search space set is associated with a control resource set, the user equipment may apply the transmission configuration indication state as a preset quasi-co-occurrence assumption for physical downlink shared channel reception.

[0380] For example, Figure 24A This is a schematic diagram illustrating the determination of a preset transmission configuration indication state considering the search space set type according to an exemplary embodiment of this disclosure. (Reference) Figure 24A The control resource set 0 associated with the first transmission configuration indication state is configured to have both non-subband full-duplex and subband full-duplex resources. Figure 24B This is a schematic diagram illustrating the allocation of resources in a control resource set according to an exemplary embodiment of this disclosure. (See reference) Figure 24B If the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume a quasi-co-position assumption for the control resource set 0 associated with the common search space set 0 in the latest time slot.

[0381] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in subband full-duplex / non-subband full-duplex symbols, the user equipment may assume a quasi-co-occurrence assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest time slot. In one embodiment, when the monitored search space set is associated with / indicated by two control resource sets, the user equipment may apply the transmission configuration indication state associated with the subband full-duplex / non-subband full-duplex symbols as a preset quasi-co-occurrence assumption for physical downlink shared channel reception.

[0382] For example, Figure 25A This is a schematic diagram illustrating the determination of a preset transmission configuration indication state considering the search space set type according to an exemplary embodiment of this disclosure. (Reference) Figure 25A User equipment specific search space set 1 is associated with control resource set 0 and control resource set 1. Control resource set 0, associated with the first transmission configuration indication state, is configured only with non-subband full-duplex resources, while control resource set 1, associated with the first transmission configuration indication state, is configured only with subband full-duplex resources. Figure 25B This is a schematic diagram illustrating the allocation of resources in a control resource set according to an exemplary embodiment of this disclosure. (See reference) Figure 25B If the time offset between the scheduled downlink control information of search space set 1 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may apply the second transmission configuration indication state associated with the subband full-duplex symbol as a preset quasi-co-occurrence assumption for physical downlink shared channel reception, and may assume a quasi-co-occurrence assumption for controlling resource set 1.

[0383] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in subband full-duplex / non-subband full-duplex symbols, the user equipment may assume a quasi-co-occurrence assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest time slot. In one embodiment, when the monitored search space set is associated with a control resource set, the user equipment may apply the transmission configuration indication state as a preset quasi-co-occurrence assumption for physical downlink shared channel reception.

(Reference) Figure 26AUser equipment-specific search space set 2 is associated with control resource set 2. Control resource set 2, associated with the third transmission configuration indication state, is configured only with non-subband full-duplex resources. Figure 26B This is a schematic diagram illustrating the allocation of resources in a control resource set according to an exemplary embodiment of this disclosure. (See reference) Figure 26B If the time offset between the scheduling downlink control information of search space set 2 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may apply the third transmission configuration indication state associated with the non-subband full-duplex symbol as the preset transmission configuration indication state, and may assume the quasi-co-position assumption for controlling resource set 2.

[0385] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in subband full-duplex / non-subband full-duplex symbols, and / or the physical downlink shared channel is scheduled in a fixed / predetermined / configured symbol position (e.g., the first / last half-slot), the user equipment may assume a quasi-co-occurrence assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest slot, wherein the user equipment may monitor only the user equipment-specific search space set in the latest slot. In one embodiment, when the monitored search space set is associated with one control resource set, the user equipment may apply a transmission configuration indication state as a preset quasi-co-occurrence assumption for physical downlink shared channel reception. In one embodiment, when the monitored search space set is associated with two control resource sets, the user equipment may apply the transmission configuration indication state associated with subband full-duplex / non-subband full-duplex symbols as preset quasi-co-occurrence assumptions for physical downlink shared channel reception, respectively.

[0386] For example, Figure 27A This is a schematic diagram illustrating the preset transmission configuration indication state of the Physical Downlink Shared Channel (PDSCH) scheduled from the downlink control information (DCI) of the search space (SS) associated with two control resource sets, according to an exemplary embodiment of this disclosure. (See reference...) Figure 27A Control resource set 0, associated with shared search space set 0 and the first transmission configuration indication state, is configured with subband full-duplex resources and non-subband full-duplex resources. Control resource set 0, associated with user equipment specific search space set 1 and the first transmission configuration indication state, is configured with non-subband full-duplex resources, while control resource set 1, associated with user equipment specific search space set 1 and the second transmission configuration indication state, is configured with subband full-duplex resources.

[0463] In one embodiment, the time offset between the downlink information and the scheduled physical downlink shared channel is greater than a threshold, and the downlink information lacks a transmission configuration indication field. In one embodiment, the user equipment may assume that the first transmission configuration indication state or quasi-co-bit assumption of the physical downlink shared channel is the same as the transmission configuration indication state or quasi-co-bit assumption applied to the control resource set for the channel associated with the downlink information.

[0464] In one embodiment, when (if or under certain circumstances) the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in subband full-duplex / non-subband full-duplex symbols, (Option 1) the user equipment may assume that the quasi-co-occurrence assumption used for the physical downlink shared channel is the same as the transmission configuration indication state or quasi-co-occurrence assumption applied to the control resource set used for the transmission of the physical downlink control channel.

[0465] For example, Figure 53A This is a schematic diagram illustrating the determination of a preset transmission configuration indication state when the scheduling offset is greater than a threshold, according to an exemplary embodiment of this disclosure. (See reference...) Figure 53A The first transmission configuration indication state associated with the shared search space set 0 and control resource set 0 is configured with non-subband full-duplex resources. Figure 53B This is a schematic diagram illustrating the allocation of search space set resources according to exemplary embodiments of this disclosure. (Reference) Figure 53B If the time offset between the scheduling downlink control information of search space set 0 and the scheduling physical downlink shared channel is less than a threshold, the user equipment may assume that the quasi-co-location assumption used to control resource set 0 is the same as the first transmission configuration indication state, wherein the first transmission configuration indication state is a preset transmission configuration indication state.

[0466] In one embodiment, the user equipment may assume that the first transmission configuration indication state or quasi-co-bit assumption of the physical downlink shared channel is the same as the transmission configuration indication state or quasi-co-bit assumption applied to the control resource set of the channel associated with downlink information. In one embodiment, if two transmission configuration indication states are configured in the first transmission configuration indication state (when or if), the user equipment may apply one of the two transmission configuration indication states associated with the same resource type of the time slot used to receive the physical downlink shared channel. In one embodiment, if two reference signals (RSs) are configured in the first transmission configuration indication state (when or if), the user equipment may apply one of the two reference signals associated with the same resource type of the time slot used to receive the physical downlink shared channel.

[0467] In one embodiment, when (if or under certain circumstances) the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in subband full-duplex / non-subband full-duplex symbols;

[0468] When (if or under certain circumstances) the control resource set is configured with two transmission configuration indication states, the user equipment may apply the transmission configuration indication states associated with subband full-duplex / non-subband full-duplex as the preset quasi-co-bit assumption for physical downlink shared channel reception.

[0469] When (if or under certain circumstances) the transmission configuration indication state is configured with two reference signals, the user equipment may apply the reference signals associated with subband full-duplex / non-subband full-duplex as the preset quasi-co-bit assumption for physical downlink shared channel reception respectively;

[0470] When (if or under certain circumstances) the reference signal is associated with two receive beams, the user equipment may apply the receive beams associated with subband full-duplex / non-subband full-duplex as a preset quasi-co-position assumption for physical downlink shared channel reception.

[0471] For example, Figure 54A This is a schematic diagram illustrating the determination of a preset transmission configuration indication state when the scheduling offset is greater than a threshold, according to an exemplary embodiment of this disclosure. (See reference...) Figure 54A The first transmission configuration indication state associated with the control resource set is configured with non-subband full-duplex resources, and the second transmission configuration indication state associated with the control resource set is configured with subband full-duplex resources. Figure 54B This is a schematic diagram illustrating the resource allocation of the search space set according to an exemplary embodiment of this disclosure. (See reference) Figure 54B If the time offset between the scheduled downlink control information of the control resource set and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume that the second transmission configuration indication state is used for the quasi-co-location assumption of the control resource set, wherein the second transmission configuration indication state is a preset transmission configuration indication state.

[0472] In one embodiment, the user equipment may not expect downlink information to be received in different resource types along with the physical downlink shared channel.

[0473] In one embodiment, when (if or under certain circumstances) the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in subband full-duplex / non-subband full-duplex symbols, (Option 2) the user equipment may not expect the scheduled physical downlink control channel and the scheduled physical downlink shared channel to be in different non-subband full-duplex symbols and subband full-duplex symbols.

[0474] For example, Figure 55A This is a schematic diagram illustrating the determination of a preset transmission configuration indication state when the scheduling offset is greater than a threshold, according to an exemplary embodiment of this disclosure. (See reference...) Figure 55A The second transmission configuration indication state associated with control resource set #2 is configured with subband full-duplex resources. Figure 55B This is a schematic diagram illustrating the resource allocation of a control resource set according to an exemplary embodiment of this disclosure. (See reference) Figure 55B If the time offset between the scheduled downlink control information of control resource set #2 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume that the preset transmission configuration indication state is used for the quasi-co-location assumption of control resource set #2.

[0475] In one embodiment, the user equipment can obtain a quasi-co-bit assumption for the physical downlink shared channel from a first transmission configuration indication state indicated by the lowest code point of the transmission configuration indication state region bit applicable to the physical downlink shared channel in the portion bandwidth (BWP) of the scheduled cell. The lowest code point of the transmission configuration indication state region bit can be predefined / fixed / configured.

[0476] In one embodiment, the user equipment may assume that the quasi-co-location assumption of the physical downlink shared channel used for scheduling derives from the transmission configuration indication state indicated by the lowest / predefined / fixed / configured code point of the transmission configuration indication state area applicable to the physical downlink shared channel in a portion of the bandwidth of the scheduling cell. In one embodiment, when (if or under certain circumstances) the time offset between the scheduled physical downlink shared channel and the control resource set associated with the monitoring search space having the lowest control resource set identifier / identifier in the latest time slot associated with the sub-band full-duplex symbol is greater than a predefined / fixed / configured value, wherein the lowest / predefined / fixed / configured code point of the transmission configuration indication state area is between code points associated with the sub-band full-duplex symbol.

[0477] For example, Figure 56 This is a schematic diagram illustrating the allocation of control resource sets for a pre-determined preset transmission configuration indication state according to an exemplary embodiment of this disclosure. (Reference) Figure 56 If the time offset between the scheduled downlink control information of control resource set #1 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume that the state of the control resource set #1 is indicated by a preset transmission configuration according to a predetermined rule.

[0478] In one embodiment, the transmission configuration indication status region is associated with the same resource type as the time slot used to receive the physical downlink shared channel.

[0479] In one embodiment, the first transmission configuration indication state is associated with separate parameters for sub-band full-duplex (SBFD) symbols and non-sub-band full-duplex symbols. In another embodiment, the first transmission configuration indication state is a uniform transmission configuration indication state.

[0480] Figure 57 This is a schematic diagram illustrating a field for indicating a transmission configuration indication state according to an exemplary embodiment of this disclosure. (Reference) Figure 57 In the MAC CE's transport configuration indication status startup, field C iThe transmission configuration indication status group index can be indicated. In the transmission configuration indication status area of ​​the downlink control information, the field of transmission configuration indication status identifier / identifier i can indicate the transmission configuration indication status identified by the transmission configuration indication status identifier / identifier. An initiated transmission configuration indication status can be associated with at least one of the following: {subband full-duplex symbol, non-subband full-duplex symbol (none)}.

[0481] If field C i Setting it to "0", the i-th transmission configuration indication status identifier / identifier may be associated with a non-subband full-duplex symbol, or used for the i-th transmission configuration indication status identifier / identifier received in a physical downlink shared channel within a non-subband full-duplex symbol. If field C i Setting it to "1" indicates that the i-th transmission configuration indication status identifier / identifier may be associated with a sub-band full-duplex symbol, or is used for the i-th transmission configuration indication status identifier / identifier received in a physical downlink shared channel within a sub-band full-duplex symbol. For example, fields C0 to C7 are set to "0" to indicate the transmission configuration indication status identifier / identifier, respectively. 0,0 To the transmission configuration indication status identifier / identifier 0,0 Associated with NOT subband full-duplex symbols. Field C8 to field C 15 Setting it to "1" indicates the transmission configuration indication status flag / identifier. 1,0 To the transmission configuration indication status identifier / identifier 1,7 Associated with sub-band full-duplex symbols. If the code point of the transmission configuration indication status area associated with a non-sub-band full-duplex symbol is, for example, "0", the transmission configuration indication status identifier / identifier indicates the transmission configuration indication status identifier / identifier. 0,0 If the code point of the transmission configuration indication status area associated with the sub-band full-duplex symbol is, for example, "7", the transmission configuration indication status identifier / identifier indicates the transmission configuration indication status identifier / identifier. 1,7 .

[0482] In one embodiment, the user equipment may obtain its quasi-co-location assumption for the scheduled physical downlink shared channel from the transmission configuration indication state indicated by the lowest / predefined / fixed / configured code point of the transmission configuration indication state region in the initiation BWP for the scheduled cell. In one embodiment, the transmission configuration indication state region code point is used when (if or in some cases) the time offset between the scheduled physical downlink shared channel and the control resource set associated with the monitoring search space having the lowest control resource set identifier / identifier in the latest time slot associated with the sub-band full-duplex symbol is greater than a predefined / fixed / configured value.

[0483] For example, Figure 58 This is a schematic diagram illustrating the allocation of control resource sets for a pre-determined preset transmission configuration indication state according to an exemplary embodiment of this disclosure. (See reference...) Figure 58 If the time offset between the scheduled downlink control information of control resource set #1 and the scheduled physical downlink shared channel is less than a threshold, the user equipment may assume a quasi-co-bit assumption for control resource set #1, for example, transmission configuration indication status identifier / identifier 1,0, wherein the preset transmission configuration indication status can be indicated by the lowest code point of the transmission configuration indication status area.

[0484] Figure 59 This is a schematic diagram illustrating a field for indicating a transmission configuration indication state according to an exemplary embodiment of this disclosure. (See reference) Figure 59 In the MAC CE's transport configuration indication status startup, field C i It can indicate a status identifier / identifier that includes a transmission configuration indication. i，2 Does the eight-byte variable exist? If this field is set to "1", it contains a transport configuration indication status identifier / identifier. i，2 The eight bytes may be present. If this field is set to "0", it contains a transport configuration indication status identifier / identifier. i，2 The eight bytes may be missing. The transport configuration indicates the status identifier / identifier. i，j The field can indicate the transmission configuration indication state identified by TCI-StateID, where i can be the code point index of the downlink control information transmission configuration indication field, and the transmission configuration indication state identifier / identifier. i，j This indicates the j-th transmission configuration indication state indicated by the i-th code point in the downlink control information transmission configuration indication field. "R" is a reserved bit and can be set to 0.

[0485] For example, field C0 is set to "1" and includes a transport configuration indication status flag / identifier. 0,2 The eight bytes are present. If the code point of the transmission configuration indication field in the downlink control information is "0", the first transmission configuration indication state associated with the non-subband full-duplex symbol is the transmission configuration indication state identifier / identifier. 0,1 The second transmission configuration indication state associated with the sub-band full-duplex symbol is a transmission configuration indication state identifier / identifier. 0,2 If the code point of the transmission configuration indication field in the downlink control information is "1", the first transmission configuration indication state associated with the non-subband full-duplex symbol is the transmission configuration indication state identifier / identifier. 1,1 The second transmission configuration indication state associated with the sub-band full-duplex symbol is a transmission configuration indication state identifier / identifier. 1,2 .

[0486] In one embodiment, if the lowest code point of the Transmission Configuration Indication field is associated with two initiated Transmission Configuration Indication states, a first Transmission Configuration Indication state associated with the same resource type for the time slot used to receive the Physical Downlink Shared Channel is applied.

[0487] In one embodiment, the user equipment may obtain its quasi-co-occurrence assumption for the scheduled physical downlink shared channel from the transmission configuration indication state indicated by the lowest code point of the transmission configuration indication field of the physical downlink shared channel in the BWP applicable to the scheduling cell. In one embodiment, the time offset between the scheduled physical downlink shared channel and the control resource set associated with the monitored search space having the lowest control resource set identifier / identifier in the latest time slot associated with the sub-band full-duplex symbol is greater than a predetermined / fixed / configured value, wherein the lowest code point of the transmission configuration indication field is between code points associated with the sub-band full-duplex symbol. In one embodiment, when the lowest code point of the transmission configuration indication field is associated with two initiated transmission configuration indication states, the user equipment may apply the lowest transmission configuration indication state identifier / identifier and / or apply the transmission configuration indication state associated with the sub-band full-duplex symbol.

[0488] In one embodiment, the user equipment may be configured with at least one transmission configuration indication state for SPS-Physical Downlink Shared Channel reception, such as a first transmission configuration indication state and a second transmission configuration indication state, wherein the first transmission configuration indication state may be configured / associated with a non-subband full-duplex resource, and / or the second transmission configuration indication state may be configured / associated with a subband full-duplex resource. In one embodiment, when (if or under certain circumstances) the SPS-Physical Downlink Shared Channel is in a non-subband full-duplex resource, the user equipment may receive the SPS-Physical Downlink Shared Channel through the first transmission configuration indication state. In one embodiment, when (if or under certain circumstances) the SPS-Physical Downlink Shared Channel is in a subband full-duplex resource, the user equipment may receive the SPS-Physical Downlink Shared Channel through the second transmission configuration indication state.

[0489] Figure 60 This is a schematic diagram illustrating an inappropriate transmission configuration indication state, according to an exemplary embodiment of this disclosure. (See reference) Figure 60Using an improperly preset transmission configuration indication state (shared transmission configuration indication state) for a scheduled physical downlink shared channel may result in performance degradation. There may be no monitoring opportunities (MOs) in the time slots of the scheduled physical downlink shared channel, where the channel is in sub-band full-duplex symbols (or in non-sub-band full-duplex symbols respectively). The monitored search space with the lowest control resource set identifier / identifier in the latest time slot is a non-sub-band full-duplex symbol (or in sub-band full-duplex symbols respectively). Therefore, a resource type-specific shared beam is required.

[0490] Figure 61A This is a schematic diagram illustrating a Media Access Control (MAC) Control Element (CE) field used to indicate the state of a transmission configuration indication, according to an exemplary embodiment of this disclosure. Reference Figure 61A In the MAC CE's transmission configuration indication state initiation, the Ci field indicates the transmission configuration indication state group index. In the transmission configuration indication field of the downlink control information, the transmission configuration indication state IDi field indicates the transmission configuration indication state identified by the transmission configuration indication state ID. An initiated transmission configuration indication can be associated with at least one of the following: {subband full-duplex symbol, non-subband full-duplex symbol (none)}.

[0491] If field C i Setting it to "0", the i-th transmission configuration indication status identifier / identifier may be associated with a non-subband full-duplex symbol, or used for the i-th transmission configuration indication status identifier / identifier for physical downlink shared channel reception in a non-subband full-duplex symbol. If field C i Setting it to "1" indicates that the i-th transmission configuration indication status identifier / identifier may be associated with a sub-band full-duplex symbol, or is used for the i-th transmission configuration indication status identifier / identifier received in a physical downlink shared channel within a sub-band full-duplex symbol. For example, fields C0 to C7 are set to "0" to indicate the transmission configuration indication status identifier / identifier, respectively. 0,0 To transport configuration indication status identifier / identifier 0,0 Associated with NOT subband full-duplex symbols. Field C8 to field C 15 Setting it to "1" indicates the transmission configuration indication status flag / identifier. 1,0 To transport configuration indication status identifier / identifier 1,7 Associated with subband full-duplex symbols. Figure 61B This is a schematic diagram illustrating the Downlink Control Information (DCI) transmission configuration indication field, according to an exemplary embodiment of this disclosure. Reference Figure 61B If the code point of the transmission configuration indication field is, for example, "0", the first transmission configuration indication state associated with the non-subband full-duplex symbol is the transmission configuration indication state identifier / identifier. 0,0The second transmission configuration indication state associated with the sub-band full-duplex symbol is a transmission configuration indication state identifier / identifier. 1,0 If the code point of the Transmission Configuration Indication field is, for example, "7", the first Transmission Configuration Indication state associated with the non-subband full-duplex symbol is the Transmission Configuration Indication state identifier / identifier. 0,7 The second transmission configuration indication state associated with the sub-band full-duplex symbol is a transmission configuration indication state identifier / identifier. 1,7 .

[0492] In one embodiment, when (if or in any case) the user equipment transmits the last symbol of a physical uplink control channel having hybrid automatic repeat request acknowledgment information corresponding to downlink control information carrying a transmission configuration indication status indication and without downlink allocation, or a physical downlink shared channel scheduled by downlink control information carrying a transmission configuration indication status indication, and when (if or in any case) the indicated transmission configuration indication status differs from the previously indicated one, the transmission configuration indication status with a transmission configuration indication status identifier / identifier may be applied from the first time slot, which may be at least a symbol after the last symbol of the physical uplink control channel (e.g., the time of beam application).

[0493] For example, Figure 62A This is a schematic diagram illustrating a media access control layer control element field for indicating a transmission configuration indication state according to an exemplary embodiment of this disclosure. (See reference) Figure 62A If the code point in the Transmission Configuration Indication field is, for example, "1", the first Transmission Configuration Indication state associated with the non-subband full-duplex symbol is the Transmission Configuration Indication state identifier / identifier. 0,1 The second transmission configuration indication state associated with the sub-band full-duplex symbol is a transmission configuration indication state identifier / identifier. 1,1 . Figure 62B This is a timing diagram illustrating the common beam initiation of duplex operation according to an exemplary embodiment of this disclosure. (See reference...) Figure 62B If the code point of the transmission configuration indication field in downlink control information #1 is "1", the transmission configuration indication status identifier / identifier associated with the non-subband full-duplex symbol is... 0,1 and the transmission configuration indication status flag / identifier associated with the sub-band full-duplex symbol 1,1 The status identifier / identifier will be indicated using the transport configuration. 0,0 and transmission configuration indication status identifier / identifier 1,0 The beamforming application is applied afterward.

[0494] In one embodiment, when (if or under certain circumstances) the offset between the received downlink control information and the corresponding physical downlink shared channel is less than a threshold:

[0495] When the indicated transmission configuration indication state is associated with the physical layer cell identifier / identifier of the serving cell (if or under certain circumstances), the indicated transmission configuration indication state associated with the subband full-duplex symbol (or non-subband full-duplex symbol) can be applied to physical downlink shared channel reception on the subband full-duplex symbol (or non-subband full-duplex symbol).

[0496] For example, Figure 63 This is a schematic diagram illustrating the selection of a transport configuration indication state associated with the same resource type according to an exemplary embodiment of this disclosure. (See reference...) Figure 63 The Transmission Configuration Indication State #0, associated with the Physical Layer Cell Identifier / Identifier of the serving cell, is associated with non-subband full-duplex symbols, while the Transmission Configuration Indication State #1, associated with the Physical Layer Cell Identifier / Identifier of the same serving cell, is associated with subband full-duplex symbols. If the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, the user equipment may apply the Transmission Configuration Indication State #1 associated with the subband full-duplex symbol to physical downlink shared channel reception on the subband full-duplex symbol.

[0497] In one embodiment, when (if or under certain circumstances) the semi-persistent scheduling physical downlink shared channel is in a non-subband full-duplex resource, the user equipment can receive the semi-persistent scheduling physical downlink shared channel via the transmission configuration indication state of the application associated with the non-subband full-duplex resource. In another embodiment, when (if or under certain circumstances) the semi-persistent scheduling physical downlink shared channel is in a subband full-duplex resource, the user equipment can receive the semi-persistent scheduling physical downlink shared channel via the transmission configuration indication state of the application associated with the subband full-duplex resource.

[0498] In one embodiment, when (if or under certain circumstances) the offset between the received downlink control information and the corresponding physical downlink shared channel is less than a threshold:

[0499] When (if or under certain circumstances) an indication's transmission configuration indication state is associated with a physical layer cell identifier / identifier that is different from the serving cell and the indication's transmission configuration indication state is associated with a subband full-duplex symbol,

[0500] The transmission configuration indication state associated with a non-subband full-duplex symbol can be applied to physical downlink shared channel reception on non-subband full-duplex symbols; and / or

[0501] User equipment may not expect the physical downlink shared channel to be scheduled in the subband full-duplex symbol.

[0502] For example, Figure 64 This is a schematic diagram illustrating the selection of a transport configuration indication state associated with the same resource type according to an exemplary embodiment of this disclosure. (See reference...) Figure 64Transmission configuration indication state #0 associated with the serving cell is associated with non-subband full-duplex symbols, while transmission configuration indication state #1 associated with non-serving cells is associated with subband full-duplex symbols. If the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, the user equipment may apply transmission configuration indication state #0 associated with non-subband full-duplex symbols to physical downlink shared channel reception on non-subband full-duplex symbols, without expecting the physical downlink shared channel to be scheduled in subband full-duplex symbols.

[0503] In one embodiment, when (if or under certain circumstances) the offset between the received downlink control information and the corresponding physical downlink shared channel is less than a threshold:

[0504] When (if or under certain circumstances) an indication's transmission configuration indication state is associated with a physical layer cell identifier / identifier that is different from the serving cell and the indication's transmission configuration indication state is associated with a subband full-duplex symbol,

[0505] The transmission configuration indication state associated with the non-subband full-duplex symbol can be applied to physical downlink shared channel reception on the non-subband full-duplex symbol; and / or

[0506] User equipment may not expect the physical downlink shared channel to be scheduled in the subband full-duplex symbol.

[0507] For example, Figure 65 This is a schematic diagram illustrating the selection of a transport configuration indication state associated with the same resource type according to an exemplary embodiment of this disclosure. (See reference...) Figure 65 The transmission configuration indication state #0 associated with the serving cell is associated with non-subband full-duplex symbols, while the transmission configuration indication state #1 associated with non-serving cells is associated with subband full-duplex symbols. If the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, the user equipment may apply the transmission configuration indication state #1 associated with the subband full-duplex symbol to the physical downlink shared channel reception on the subband full-duplex symbol, and does not expect the physical downlink shared channel to be scheduled in non-subband full-duplex symbols.

[0508] In one embodiment, when (if or under certain circumstances) the offset between the received downlink control information and the corresponding physical downlink shared channel is less than a threshold:

[0509] When (if or under certain circumstances) an indication's transmission configuration indication state is associated with a physical layer cell identifier / identifier that is different from the serving cell and the indication's transmission configuration indication state is associated with a subband full-duplex symbol,

[0510] The transmission configuration indication state associated with the sub-band full-duplex symbol (or non-sub-band full-duplex symbol) can be applied to physical downlink shared channel reception on the sub-band full-duplex symbol (or non-sub-band full-duplex symbol).

[0511] For example, Figure 66 This is a schematic diagram illustrating the selection of a transport configuration indication state associated with the same resource type according to an exemplary embodiment of this disclosure. (See reference...) Figure 66 The transmission configuration indication state #0 associated with the serving cell is associated with a non-subband full-duplex symbol, while the transmission configuration indication state #1 associated with a non-serving cell is associated with a subband full-duplex symbol. If the time offset between the scheduled downlink control information and the scheduled physical downlink shared channel is less than a threshold, the user equipment can apply the transmission configuration indication state #1 associated with the subband full-duplex symbol to the physical downlink shared channel reception on the subband full-duplex symbol.

[0512] Figure 67 This is a schematic diagram illustrating the allocation of channel state information-reference signal resources for each sub-band full-duplex symbol according to an exemplary embodiment of this disclosure. (Reference) Figure 67 In the allocation of channel state information-reference signal resources, there may be two additional parameters.

For example, channel state information reporting is performed based on the most recent channel state information-reference signal associated with sub-band full-duplex and the channel state information-reference signal associated with non-sub-band full-duplex.

(See reference) Figure 81 There may be a situation where (if or under certain circumstances) the user equipment is configured with the higher-layer parameter reportQuantity set to “cri-RI-PMI-CQI” for channel state information reporting.

[0535] When (if or under certain circumstances) the most recent channel state information-reference signal used for channel state information reporting is a sub-band full-duplex channel state information-reference signal; and / or

[0536] When (if or under certain circumstances) the channel state information from the sub-band full-duplex channel state information-reference signal and the non-sub-band full-duplex channel state information-reference signal may have the same CRI and RI values. For example, if the channel state information-reference signal associated with sub-band full-duplex and the channel state information-reference signal associated with non-sub-band full-duplex have the same CRI and RI values, then as Figure 81 The diagram shows the channel state information (CSI) reports for the most recent CSI-reference signal associated with subband full-duplex and for CSI-reference signals associated with non-subband full-duplex. Subband PMI / CQI may originate from measurements of CSI-reference signals associated with subband full-duplex in downlink subband frequency resources. Subband PMI / CQI may also originate from measurements of CSI-reference signals associated with non-subband full-duplex in downlink out-of-subband frequency resources.

[0537] In one embodiment, when (if or under certain circumstances) the user equipment is configured with the higher-layer parameter reportQuantity set to "cri-RI-PMI-CQI" for channel state information reporting, a situation may arise where...

[0538] When (if or under certain circumstances) the most recent channel state information-reference signal used for channel state information reporting is a sub-band full-duplex channel state information-reference signal;

The start of a portion of the bandwidth might be, for example, the second physical resource block. There might be seven subbands A0, A1, A2, A3, A4, A5, and A6 allocated for PMI / CQI reporting.

[0545] In one embodiment, regarding the Channel Quality Indicator (CQI), when the higher-level parameter cqi-BitsPerSubband in the Channel State Information Report Configuration (CSI-ReportConfig) is not configured (if or under certain circumstances), a 2-bit subband differential CQI can be defined for each subband index s as follows:

[0546] Subband offset level = Subband CQI index - Wideband CQI index; and / or

[0547] The mapping from 2-bit subband differential CQI values ​​to offset levels is shown in the table.

[0548] In one embodiment, there may be a situation where, (if or under certain circumstances) the user equipment is configured with a channel state information reporting configuration, its high-level parameter reportQuantity is set to 'cri-RI-PMI-CQI':

[0549] When (if or under certain circumstances) the channel state information-reference signal most recently used for channel state information reporting is a sub-band full-duplex channel state information-reference signal;

[0550] When (if or under certain circumstances) the channel state information from the sub-band full-duplex channel state information-reference signal and the non-sub-band full-duplex channel state information-reference signal may have different CRI and / or RI values; and / or

[0551] When (if or under what circumstances) the higher-level parameter cqi-BitsPerSubband in the Channel State Information Reporting configuration is configured.

[0552] by Figure 81 As an example, if there are different CRI and / or RI values ​​between the Channel State Information (CSI) reference signal associated with sub-band full-duplex and the CSI reference signal associated with non-sub-band full-duplex, then the most recent CSI report for both the sub-band full-duplex and non-sub-band full-duplex CSI reference signals is executed. It should be noted that the CSI from the non-sub-band full-duplex CSI reference signal may be outdated. Therefore, this CSI information may not be useful for downlink scheduling in the base station network.

[0561] In one embodiment, there may be a situation where, (if or under certain circumstances) the user equipment is configured with a channel state information reporting configuration, its high-level parameter reportQuantity is set to 'cri-RI-PMI-CQI':

[0562] When (if or under certain circumstances) the channel state information-reference signal most recently used for channel state information reporting is a non-subband full-duplex channel state information-reference signal.

[0563] For example, Figure 86 This is a schematic diagram illustrating the channel measurement time limitation according to an exemplary embodiment of this disclosure. (Reference) Figure 86 The most recent channel state information (CSO) reference signal associated with the non-subband full-duplex is used for CSO reporting, but the most recent CSO reference signal associated with the subband full-duplex is not used for CSO reporting. Note that in this case, the conventional behavior is followed, i.e., the latest CSO information is based on the most recent CSO reference signal.

[0564] also, Figure 87 This is a schematic diagram illustrating the allocation of channel measurement resources according to an exemplary embodiment of this disclosure. (See reference) Figure 87 Subband PMI / CQI may originate from measurements of channel state information-reference signals associated with non-subband full-duplex frequency resources within the downlink subband.

[0565] Figure 88 This is a schematic diagram illustrating an initial channel state information report based on a first sub-band full-duplex channel state information-reference signal according to an exemplary embodiment of this disclosure. (Reference) Figure 88There may be a situation where (if or under certain circumstances) the physical downlink shared channel carries an SP CSI-RS (Semi-Persistent CSI-RS) activation command or a P CSI-RS (Periodic CSI-RS) resource reconfiguration. A potential issue is whether or how to report the subband PMI / CQI for frequency resources outside the downlink subband.

[0566] Figure 89 This is a schematic diagram illustrating the allocation of channel state information reporting resources according to an exemplary embodiment of this disclosure. (See reference...) Figure 89 Regarding the channel state information-reference signal associated with subband full-duplex, in frequency resources outside the downlink subband, the subband CQI index may be set to "0" or the subband differential CQI value may be set to "3". The subband PMI / CQI may originate from the measurement results of the subband full-duplex channel state information-reference signal in frequency resources inside the downlink subband.

[0567] Figure 90 This is a schematic diagram illustrating the sub-band full-duplex and non-sub-band full-duplex channel state information-reference signal configuration according to an exemplary embodiment of this disclosure. Reference Figure 90 The parameter “nzp-CSI-RS-Resource” indicates “firstresourceMapping”, where qcl-InfoPeriodicCSI-RS is the first transmission configuration indicator status identifier / identifier configuration for non-subband full-duplex type in the traditional configuration, and “second resourceMapping”, where qcl-InfoPeriodicCSI-RS is the first or second transmission configuration indicator status identifier / identifier configuration for subband full-duplex type.

[0568] In one embodiment, only allocated physical resource blocks within downlink available physical resource blocks are considered valid for the physical downlink shared channel.

[0569] In one embodiment, an allocated physical resource block that falls outside the downlink available physical resource block is considered invalid. In some embodiments, an allocated physical resource block that falls outside the downlink available physical resource block should not be used.

[0570] In one embodiment, the user equipment may receive a channel state information reporting configuration, wherein for channel state information reporting subbands that overlap with at least one physical resource block within a downlink available physical resource block and at least one physical resource block outside a downlink available physical resource block, only the physical resource blocks within the downlink available physical resource block are used for reporting. The user equipment may report channel state information according to the channel state information reporting configuration.

[0571] In one embodiment, the user equipment can receive a channel state information report configuration, wherein the channel state information report configuration is associated with channel state information-reference signal resources. For channel state information-reference signal resources overlapping with the sub-band full-duplex sub-band boundary, only the channel state information-reference signal frequency resources within the downlink available physical resource block are valid. The user equipment can report channel state information according to the channel state information report configuration.

[0572] In one embodiment, the user equipment can receive a channel state information report configuration, wherein the channel state information report configuration is associated with channel state information-reference signal resources, and the channel state information-reference signal mapping applies only to channel state information-reference signal resources within downlink available physical resource blocks. The user equipment can report channel state information according to the channel state information report configuration.

[0573] In one embodiment, the user equipment may receive a channel state information reporting configuration, wherein the channel state information reporting configuration is associated with channel state information-reference signal resources, and the channel state information-reference signal resources mapped to resource blocks outside the downlink available physical resource blocks are traversed. The user equipment may report channel state information according to the channel state information reporting configuration.

[0574] Figure 91 This is a schematic diagram illustrating the reporting of each sub-band full-duplex channel state information - reference signal sub-band channel state information according to an exemplary embodiment of this disclosure. (Reference) Figure 91 There might be a channel state information (CSA) reporting instance where the most recent CSA-reference signal associated with subband full-duplex and the CSA-reference signal associated with non-subband full-duplex are used for CSA reporting. To reduce CSA overhead, the user equipment may not need to report subband precoding matrix indications / channel quality indications for downlink subband external frequency resources. For example, the "subbands6" of the first CSI-ReportingBand of the CSA-reference signal associated with non-subband full-duplex is set to "111111", while the "subbands6" of the second CSI-ReportingBand of the CSA-reference signal associated with subband full-duplex is set to "110011", where "0" corresponds to frequency resources outside the downlink subband.

[0575] There may be multiple channel state information selection indicators. For example, Figures 92A to 92C This is a schematic diagram illustrating a channel state information selection indication according to an exemplary embodiment of this disclosure. (Reference) Figure 92AChannel state information report instances can be non-subband full-duplex channel state information - reference signal channel state information and subband full-duplex channel state information - reference signal channel state information. (Reference) Figure 92B When the channel state information of a non-subband full-duplex channel state information - reference signal might not be reported due to lack of updates, the channel state information reporting instance might be the channel state information of a subband full-duplex channel state information - reference signal. Figure 92C When the channel state information (CSO) of a sub-band full-duplex CSO-reference signal might not be reported due to lack of updates, the CSO reporting instance might be the CSO of a non-sub-band full-duplex CSO-reference signal. However, in these cases, it can be problematic how the base station network knows which one or two CSO information entries to report.

[0576] Table (3) shows the channel state information selection indication:

[0577] Table (3)

[0578]

[0579] In one embodiment, there may be a situation where (if or in this case) the user equipment is configured to report dynamic channel state information of the non-subband full-duplex channel state information-reference signal and / or the subband full-duplex channel state information-reference signal. For example, Figures 93A to 93B This is a schematic diagram illustrating a channel state information selection indication according to an exemplary embodiment of this disclosure. (Reference) Figure 93A If the channel state information selection indicator value is set to "3", the channel state information of the non-subband full-duplex channel state information - reference signal will be reported, but the channel state information of the subband full-duplex channel state information - reference signal will not be reported because it has not been updated. Figure 93B If the channel state information selection indicator value is set to "2", the channel state information of the sub-band full-duplex channel state information - reference signal will be reported, but the channel state information of the non-sub-band full-duplex channel state information - reference signal will not be reported because it has not been updated.

[0580] In one embodiment, there may be a situation where (if or in this case) the user equipment is configured to report two channel state information: non-subband full-duplex channel state information-reference signal and subband full-duplex channel state information-reference signal. For example... Figures 94A to 94B This is a schematic diagram illustrating a channel state information selection indication according to an exemplary embodiment of this disclosure. (Reference) Figure 94AIf the channel state information selection indicator value is set to "1", the channel state information of the sub-band full-duplex channel state information - reference signal will be reported, but the channel state information of the non-sub-band full-duplex channel state information - reference signal will not be reported because it has not been updated. Figure 94B If the channel state information selection indicator value is set to "0", the channel state information of the non-subband full-duplex channel state information - reference signal will be reported, but the channel state information of the subband full-duplex channel state information - reference signal will not be reported because it has not been updated.

[0581] Figure 95 This is a timing diagram illustrating a channel state information selection indication according to an exemplary embodiment of this disclosure. (See reference...) Figure 95 If there is a channel state information (CSO) reference signal associated with non-subband full-duplex, the CSO information of the non-subband full-duplex CSO reference signal may be discarded or expired due to its low priority. If there is a CSO reference signal associated with subband full-duplex and the channel state information selection indicator value is set to "3", the CSO information of the full-duplex CSO reference signal may be reported.

[0582] In one embodiment, the channel state information selection indicator may be configurable. In one embodiment, when (if or in this case) the channel state information selection indicator is not configured:

[0583] User equipment can report two channel state information: non-subband full-duplex channel state information - reference signal and subband full-duplex channel state information - reference signal, and / or

[0584] User equipment can preset the priority of channel state information, for example...

[0585] High priority: Channel state information of non-subband full-duplex channel state information-reference signal (or subband full-duplex channel state information-reference signal);

[0586] Low priority: Channel state information of sub-band full-duplex channel state information - reference signal (or non-sub-band full-duplex channel state information - reference signal).

[0587] In one embodiment, for subband full-duplex channel state information reporting, the user equipment may be configured to at least one of the following:

[0588] Both:

[0589] Channel state information for non-subband full-duplex channel state information - reference signal and subband full-duplex channel state information - reference signal;

[0590] dynamic:

[0591] Channel state information of non-subband full-duplex channel state information - reference signal and / or subband full-duplex channel state information - reference signal.

[0592] In one embodiment, the user equipment can be configured to prioritize channel state information as follows:

[0593] Non-subband full-duplex channel state information - the channel state information of the reference signal can have higher priority;

[0594] Subband full-duplex channel state information - the channel state information of the reference signal can have a higher priority;

[0595] None: The priority of channel state information is determined by the user equipment.
