Description

Technical Field

[0001] This invention relates to a method for using a user device, a method for using a network device, and a user device. Prior Technology

[0002] Figure 1 is a schematic diagram illustrating Static Time Division Duplex (TDD) and Subband Full Duplex (SBFD). Referring to Figure 1, a new type of time resource, subband full duplex, is introduced in duplex operation. In subband full duplex, downlink and uplink subbands are allocated in the same symbol. However, in time division duplex, downlink and uplink subbands are not allocated in the same symbol.

[0003] Figure 2 is a schematic diagram illustrating simultaneous transmission (Tx) and reception (Rx) in a multi-panel transmission scheme. Referring to Figure 2, separate antenna panels can be supported to enable simultaneous transmission / reception and reduce interference between adjacent channels. For example, panel 1 is used for uplink transmission, and panel 2 is used for downlink reception. However, the same beam used for downlink reception (e.g., beam #A) may exist not only in sub-band full-duplex resources but also in non-sub-band full-duplex resources, leading to performance degradation due to inappropriate beam application for downlink reception in both sub-band and non-sub-band full-duplex resources.

Referring to Figure 4A, the search space set used for the entity downlink control channel can be a common type monitored by a set of user equipment, such as control resource set zero containing system information.

[0040] Figure 4B is a schematic diagram illustrating a user equipment-specific search space set. Referring to Figure 4B, the search space set used for a physical downlink control channel can be a user equipment-specific type monitored by a single user equipment, such as for downlink / uplink scheduling.

[0041] Figure 5A is a schematic diagram illustrating downlink (DL) scheduling on a non-uniform Transport Configuration Indication (TCI) framework. Referring to Figure 5A, if the scheduling offset between the scheduled downlink control information and the scheduled entity 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-location assumption for the entity downlink shared channel indicated by the Transport Configuration Indication field in the scheduled downlink control information.

[0042] Figure 5B is a schematic diagram illustrating the code points in the transmission configuration indication field. Referring to Figure 5B, in the transmission configuration indication field of downlink control information, the code points indicate the transmission configuration indication status identification code. For example, code point "0" indicates the transmission configuration indication status identification code ₀.

[0043] Figure 6A is a schematic diagram illustrating two transmission configuration indication states for downlink reception, while Figure 6B is a schematic diagram illustrating the allocation of control resource set (CORESET) resources for an entity downlink shared channel with transmission configuration indication fields. Referring to Figures 6A and 6B, there may be two control resource sets associated with two transmission configuration indication states respectively. If the scheduling offset between the scheduled downlink control information and the scheduled entity downlink shared channel is less than a threshold, the user equipment may assume that the quasi-co-bit assumption of the entity downlink shared channel used for the control resource set is associated with the monitored search space having the lowest control resource set identifier in the nearest time slot. For example, the lowest control resource set identifier is "#0".

[0044] Figure 7A is a schematic diagram illustrating two transmission configuration indication states for downlink reception, while Figure 7B is a schematic diagram illustrating the allocation of control resource sets for an entity downlink shared channel without a transmission configuration indication field. Referring to Figures 7A and 7B, there may be two control resource sets associated with two transmission configuration indication states, respectively. If the scheduling offset between the scheduled downlink control information and the scheduled entity downlink shared channel is greater than or equal to a threshold, and if the downlink control information does not present a transmission configuration indication field, the user equipment may assume that the quasi-co-occurrence assumption of the entity downlink shared channel used for the control resource set is associated with the monitored search space that has the lowest control resource set identifier in the nearest time slot. For example, the lowest control resource set identifier is "#0".

[0045] Figure 8 is a schematic diagram illustrating the downlink (DL) scheduling transmission configuration indication framework. Referring to Figure 8, when a user equipment transmits the last symbol of a PUCCH containing downlink control information that corresponds to a transmission configuration indication status indication without downlink allocation, or HARQ-ACK information for an entity downlink shared channel scheduled by downlink control information carrying a transmission configuration indication status indication, and if the indicated transmission configuration indication status differs from a previous indication, the indication of the transmission configuration indication status with a transmission configuration indication status identifier may be applied starting from the first time slot, which may be at least a symbol after the last symbol of the PUCCH (e.g., the beam application time). For example, if the transmission configuration indication field of downlink control information #1 indicates transmission configuration indication status #y, transmission configuration indication status #y will be applied after beam application using transmission configuration indication status #x.

[0046] Figure 9A is a schematic diagram illustrating resource allocation in Time Division Duplex (TDD). Referring to Figure 9A, in TDD, time-domain resources may be split between downlink and uplink, which may lead to increased uplink latency.

[0047] Figure 9B is a schematic diagram illustrating resource allocation in Sub-Band Full-Duplex (SBFD). Referring to Figure 9B, in Sub-Band Full-Duplex, the feasibility of simultaneous downlink and uplink is allowed. Sub-bands do not overlap with full-duplex on the gNB side within the traditional time-division duplex band.

[0048] Figure 9C is a schematic diagram illustrating beam management for non-sub-band full-duplex symbols, while Figure 9D is a schematic diagram illustrating beam management for sub-band full-duplex symbols. Referring to Figures 9C and 9D, the network may prepare two sets of reference signals for beam management, for example, A set of features for non-subband full-duplex communication, such as first channel status information reporting; Another set is used for sub-band full-duplex, for example, second channel status information reporting.

[0049] Figure 10 is a schematic diagram illustrating the scheduling downlink control information used to determine time and frequency resources. Referring to Figure 10, a preset transmission configuration indication state is configured for potential entity downlink shared channel reception, regardless of resource type. When scheduling downlink control information is used to determine time and / or frequency resources, the preset transmission configuration indication state used to control the reception of non-subband full-duplex symbols may be used for potential entity downlink shared channel reception in subband full-duplex symbols, resulting in performance loss or a reduction in entity downlink shared channels scheduled using inappropriate preset transmission configuration indication states. Therefore, for downlink (e.g., entity downlink control channel) reception in full-duplex operation, the transmission configuration indication state for each resource type will be considered. The preset transmission configuration indication state determination for entity downlink shared channel reception on both non-uniform and uniform transmission configuration indication frameworks will be considered.

[0050] Figure 11 is a schematic diagram illustrating a wireless communication network architecture 1 according to an exemplary embodiment of the present disclosure. Referring to Figure 11, the 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, and one or more optional network elements providing network connectivity.

The base station NW can connect to a network via a wireless interface to serve one or more user devices.

[0054] A base station (BS) NW (or network device) is operable to provide wireless coverage to a specific geographic area using multiple cells contained in a radio access network. The base station NW supports the operation of the cells. Each cell is operable to provide service to at least one user equipment (User Equipment) within its wireless coverage area. Specifically, each cell (often referred to as a serving cell) can provide service to one or more User Equipments within its wireless 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 User Equipment within its wireless coverage area). The base station NW can communicate with one or more User Equipments in a wireless communication system through multiple cells. It should be noted that, for uplink, the User Equipment is the transmitter performing uplink transmission, and the network (node) is the receiver performing uplink reception. For downlink, the User Equipment is the receiver performing downlink reception, and the network (node) is the transmitter performing downlink transmission.

[0055] A base station NW may include a network node NN and one or more TRPs, such as TRP#1 and TRP#2.

[0057] A TRP (e.g., TRP#1 or TRP#2), also known as a Remote Radio Header (RRH), may be a transceiver under 5G NR and / or 4G radio communication system protocols. A TRP can communicatively connect to a Network Node (NN). The NN can connect in the radio communication system through one or more TRPs to serve one or more user equipments. For example, TRP#1 and TRP#2 serve one user equipment, while TRP#2 serves another user equipment, but this is not limited to this.

[0058] As mentioned above, the NR frame structure is designed to support flexible configuration to accommodate various next-generation (e.g., 5G) communication requirements, such as enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC), while meeting high reliability, high data rate, and low latency requirements. 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. The coding scheme can be configured according to channel conditions and / or service applications.

[0059] 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 situations: A exists alone, A and B exist simultaneously, or B exists alone. In addition, the character " / " in this disclosure generally indicates that the related objects are in an "or" relationship.

[0060] To facilitate understanding of the technical solutions of the embodiments disclosed herein, the technical concepts related to the embodiments disclosed herein are described below.

[0061] Figure 12 is a flowchart illustrating a method according to an exemplary embodiment of the present disclosure. Referring to Figure 12, this 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 for receiving 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 for receiving downlink information. The spatial-domain information may indicate resource allocation in the spatial domain.

[0062] The user equipment receives downlink information for the scheduling entity downlink shared channel (PDSCH) (step S1220). The downlink information may be, for example, a control resource set identifier, a search space set identifier, a transmission configuration indication status identifier, a reference reference signal identifier, and / or space reception parameters. The user equipment can configure its downlink information reception based on the downlink information.

[0063] 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.

[0064] 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.

[0065] In one embodiment, the received downlink information is associated with a first resource type and a second resource type (both).

[0066] In one embodiment, the time offset between downlink information and the entity downlink shared channel is less than a threshold. The time unit for the time offset can be a time slot, a symbol, or other time unit.

[0067] 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 identification code in the latest time slot.

[0068] In one embodiment, the latest time slot is associated with the same resource type as the time slot used for receiving the downlink shared channel of the entity.

[0069] 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 a quasi-co-location assumption for the control resource set associated with the monitored search space having the lowest control resource set identification code in the latest time slot, wherein the latest time slot may be associated with a sub-band full-duplex / non-sub-band full-duplex symbol respectively.

[0070] For example, Figure 13A is a schematic diagram illustrating the association between control resource sets and resource types, according to an example embodiment of this disclosure. Referring to Figure 13A, control resource set #1 associated with a first transmission configuration indication state is configured as a non-sub-band full-duplex resource, while control resource set #2 associated with a second transmission configuration indication state is configured as a sub-band full-duplex resource. Figure 13B is a schematic diagram illustrating the allocation of control resource sets, according to an example embodiment of this disclosure. Referring to Figure 13B, if the time offset between the downlink control information scheduled by control resource set #1 and the downlink shared channel of the scheduled entity is less than a threshold, the user equipment may assume a quasi-co-location assumption for control resource set #1 in the latest time slot.

[0071] 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 a quasi-co-position assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier in the latest time slot, wherein the lowest control resource set 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, and / or the latest time slot is selected from the time slot associated with the control resource set associated with the same resource type as the scheduled physical downlink shared channel and / or the time slot associated with the control resource set associated with both resource types.

[0072] For example, Figure 14A is a schematic diagram illustrating the association between control resource sets and resource types, according to an example embodiment of this disclosure. Referring to Figure 14A, control resource set #1 associated with a first transmission configuration indication state is configured as a non-sub-band full-duplex resource, while control resource set #3 associated with a third transmission configuration indication state is configured as a sub-band full-duplex resource and a non-sub-band full-duplex resource. Figure 14B is a schematic diagram illustrating the allocation of control resource sets, according to an example embodiment of this disclosure. Referring to Figure 14B, if the time offset between the downlink control information scheduled by control resource set #1 and the downlink shared channel of the scheduled entity is less than a threshold, the user equipment may assume a quasi-co-location assumption for control resource set #1 in the latest time slot.

[0073] In one embodiment, the minimum control resource set identifier is selected from at least one control resource set associated with the same resource type as the downlink shared channel of the receiving entity.

[0074] 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 a quasi-co-position assumption for the control resource set associated with the monitored search space having the lowest control resource set identification code in the latest time slot, wherein the lowest control resource set identification code 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.

[0075] For example, Figure 15A is a schematic diagram illustrating the association between control resource sets and resource types, according to an example embodiment of this disclosure. Referring to Figure 15A, control resource set #3, associated with the third transmission configuration indication state, is configured as a sub-band full-duplex resource and a non-sub-band full-duplex resource. Figure 15B is a schematic diagram illustrating the resource allocation of control resource sets, according to an example embodiment of this disclosure. Referring to Figure 15B, if the time offset between the downlink control information scheduled by control resource set #3 and the downlink shared channel of the scheduled entity is less than a threshold, the user equipment may assume a quasi-co-location assumption for control resource set #3 in the latest time slot.

[0076] 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 a quasi-co-position assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier in the latest time slot, wherein the lowest control resource set 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.

[0077] For example, Figure 16A is a schematic diagram illustrating the association between control resource sets and resource types, according to an example embodiment of this disclosure. Referring to Figure 16A, control resource set #1 associated with a first transmission configuration indication state is configured as a non-sub-band full-duplex resource, while control resource set #3 associated with a third transmission configuration indication state is configured as a sub-band full-duplex resource and a non-sub-band full-duplex resource. Figure 16B is a schematic diagram illustrating the resource allocation of control resource sets, according to an example embodiment of this disclosure. Referring to Figure 16B, if the time offset between the downlink control information scheduled by control resource set #3 and the downlink shared channel of the scheduled entity is less than a threshold, the user equipment may assume a quasi-co-location assumption for control resource set #3 having two resource types.

[0078] 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.

[0079] 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 a quasi-co-bit assumption for the control resource set associated with the monitored search space having the lowest control resource set identifier in the latest time slot, wherein the lowest control resource set 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 via, for example, RRC, wherein the control resource set pool index value may be associated with a resource type.

[0080] For example, Figure 17A is a schematic diagram illustrating the association between control resource sets and resource types, according to an example embodiment of this disclosure. Referring to 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-sub-band full-duplex resources. There are also control resource sets #3 associated with the 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 sub-band full-duplex resources.

[0081] Figure 17B is a schematic diagram illustrating the allocation of resources in the control resource set, according to an example embodiment of this disclosure. Referring to Figure 17B, if the time offset between the downlink control information scheduled by control resource set #3 and the downlink shared channel of the scheduled entity is less than a threshold, the user equipment may assume the quasi-co-location assumption used by control resource set #3 associated with the sub-band full-duplex resources in the latest time slot.

[0082] In one embodiment, the user equipment may assume a quasi-co-bit assumption with the lowest control resource set identifier among multiple control resource sets configured with group index values ​​of the same type as the time slots of the downlink shared channel of the receiving entity.

[0083] 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 a quasi-co-bit assumption with the lowest control resource set identification code in the control resource set configured with the control resource set pool index value associated with the sub-band full-duplex / non-sub-band full-duplex symbol, respectively.

[0084] For example, Figure 18 is a schematic diagram illustrating the association between control resource sets and resource types and their resource allocation, according to an example embodiment of this disclosure. Referring to Figure 18, there are control resource sets #1 associated with a first transmission configuration indication state and control resource sets #2 associated with a second transmission configuration indication state, these control resource sets are configured with control resource set pool index 0 associated with non-sub-band full-duplex resources, and there are control resource sets #3 associated with a third transmission configuration indication state and control resource sets #4 associated with a fourth transmission configuration indication state, these control resource sets are configured with control resource set pool index 1 associated with sub-band full-duplex resources. If the downlink control information scheduled by control resource set #1 has a time offset less than a threshold from the scheduled entity downlink shared channel, the user equipment may assume the quasi-co-bit assumption used by control resource set #1 configured with control resource set pool index 0 associated with non-sub-band full-duplex resources.

[0085] 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 identification code 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.

[0086] For example, Figure 19 is a schematic diagram illustrating the association between control resource sets and resource types and their resource allocation, according to an example embodiment of this disclosure. Referring to Figure 19, 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 #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-sub-band 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 #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 sub-band full-duplex resources. If the downlink control information scheduled by control resource set #1 has a time offset less than a threshold from the scheduled entity downlink shared channel, 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-sub-band full-duplex resources.

[0087] 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 a quasi-co-bit assumption with the lowest control resource set identification code in the control resource set configured with the control resource set pool index value associated with the sub-band full-duplex / non-sub-band full-duplex symbol, respectively. Option 1: A control resource set can be configured with one or two control resource set pool index values. 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).

[0088] 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 a quasi-co-bit assumption with the lowest control resource set identification code in the control resource set associated with the sub-band full-duplex / non-sub-band full-duplex symbol, respectively. 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 sub-band full-duplex and non-sub-band full-duplex.

[0089] In one embodiment, the user equipment may assume a quasi-co-location assumption for a set of control resources associated with a monitored search space, which has the lowest control resource set identifier in the latest time slot and is located among a plurality of control resource sets associated with a common type of the search space set.

[0090] 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 a quasi-co-occurrence assumption for the control resource set associated with the monitored search space. This control resource set has the lowest control resource set identifier in the latest time slot and is located among 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.

[0091] For example, Figure 20A 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. Referring to Figure 20A, a first transmission configuration indication state associated with control resource set 0 associated with a common search space set is configured with sub-band full-duplex symbols and non-sub-band full-duplex symbols. A first state associated with control resource set 0 associated with a user equipment-specific search space set is configured with only non-sub-band full-duplex symbols, while a second state associated with control resource set 1 associated with a user equipment-specific search space set is configured with only sub-band full-duplex symbols.

[0092] Figure 20B is a schematic diagram illustrating the allocation of control resource sets according to an exemplary embodiment of the present disclosure. Referring to Figure 20B, if the time offset between the scheduling downlink control information of search space set 1 with user equipment specific type and the downlink shared channel of the scheduled entity is less than a threshold, the user equipment may assume a quasi-co-location assumption for control resource set 0 associated with search space set 0.

[0093] In one embodiment, the user equipment may assume a quasi-co-location assumption for control resource sets associated with the monitored search space. This control resource set has the lowest control resource set identifier in the latest time slot 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 time slot, 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: downlink control channels for first-type entities associated with system information; and downlink control channels for second-type entities not associated with system information.

[0094] 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 in the latest time slot and is located among multiple control resource sets associated with a common type of 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 among the multiple search space sets with the same highest priority.

[0095] In one embodiment, when the time offset between the scheduled downlink control information and the scheduled entity downlink shared channel is less than a threshold, and this entity downlink shared channel is scheduled in a sub-band full-duplex / non-sub-band full-duplex symbol, the user equipment may assume a quasi-co-location 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: Type 0 - Entity Downlink Control Channel; Type 0A - Entity Downlink Control Channel; Type 1 - Entity Downlink Control Channel; Type 2 - Entity Downlink Control Channel; Type 3 - Entity Downlink Control Channel. 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 among the multiple search space sets with the same highest priority.

[0096] For example, Figure 21 is a schematic diagram illustrating the determination of a preset transmission configuration indication state considering the search space set type according to an example embodiment of this disclosure. Referring to Figure 21, the first transmission configuration indication state associated with control resource set 0, which is associated with a shared search space set configured with a type 0-entity downlink control channel, 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 a type 3-entity downlink control channel, 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 a type 3-entity downlink control channel, is configured with only sub-band full-duplex symbols. If the time offset between the scheduled downlink control information and the scheduled entity downlink shared channel is less than a threshold, the user equipment may assume a quasi-co-position assumption for control resource set 0 associated with the shared type search space set 0 configured with a type 0-entity downlink control channel in the latest time slot.

[0097] 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 sub-band full-duplex / non-sub-band 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 identification code in the latest time slot, wherein the latest time slot may be associated with sub-band full-duplex / non-sub-band full-duplex symbols respectively.

[0098] For example, Figure 22A 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 the present disclosure. Referring to Figure 22A, the third state associated with control resource set 2 associated with the user equipment-specific search space set is configured with only non-sub-band full-duplex symbols, while the fourth state associated with control resource set 4 associated with the user equipment-specific search space set is configured with only sub-band full-duplex symbols. Figure 22B is a schematic diagram illustrating the allocation of control resource sets according to an exemplary embodiment of the present disclosure. Referring to Figure 22B, if the time offset between the scheduled downlink control information and the scheduled entity downlink shared channel is less than a threshold, the user equipment may assume a quasi-co-position assumption for control resource set 2 associated with user equipment-specific search space set 2 in the latest time slot.

[0099] Figure 23 is a flowchart illustrating a method for applying a transmission configuration indication state with a control resource set according to an example embodiment of the present disclosure. Referring to Figure 23, the user equipment determines whether there are any monitored search space sets in the latest time slot (step S2310). If there are one or more monitored search space sets in the latest time slot, the user equipment determines whether at least one search space set in the monitored search space sets in the latest time slot is configured as a common type (step S2320). If there are no search space sets configured as a common type in the monitored search space sets in the latest time slot (e.g., only search space sets configured as user equipment specific), the user equipment determines whether the resource type of the latest time slot is the same as the resource type received by the physical downlink shared channel (step S2330). If the resource type of the latest time slot is the same as the resource type received by the physical downlink shared channel, the user equipment may apply a transmission configuration indication state associated with the lowest control resource set identifier in the latest time slot (step S2340). If the latest time slot is different from the resource type received by the physical downlink shared channel, 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. 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.

[0100] However, if one or more search space sets are configured as a 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).

[0172] In one embodiment, when (if or under certain circumstances) the time offset between the scheduling downlink control information and the scheduled physical downlink shared channel is less than a threshold, wherein the physical downlink shared channel is scheduled in sub-band full-duplex / non-sub-band full-duplex symbols; When (if or under certain circumstances) the control resource set configuration has two transmission configuration indication states, the user equipment can apply the transmission configuration indication states associated with sub-band full-duplex / non-sub-band full-duplex as the preset quasi-co-bit assumption for entity downlink shared channel reception, respectively; When (if or under certain circumstances) the transmission configuration indicates that there are two reference signals, the user equipment can apply the reference signals associated with sub-band full-duplex / non-sub-band full-duplex respectively as the preset quasi-co-bit assumption for physical downlink shared channel reception; When (if or under certain circumstances) the reference signal is associated with two receive beams, the user equipment can apply the receive beams associated with sub-band full-duplex / non-sub-band full-duplex as the preset quasi-co-location assumption for physical downlink shared channel reception.

[0173] For example, FIG54A 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 the present disclosure. Referring to FIG54A, a first transmission configuration indication state associated with a control resource set is configured with non-subband full-duplex resources, and a second transmission configuration indication state associated with a control resource set is configured with subband full-duplex resources. FIG54B is a schematic diagram illustrating the resource allocation of a search space set according to an exemplary embodiment of the present disclosure. Referring to FIG54B, if the time offset between the scheduling downlink control information of the control resource set and the scheduling entity 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.

[0174] In one embodiment, the user equipment may not expect downlink information and physical downlink shared channels to be received in different resource types.

[0175] 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 sub-band full-duplex / non-sub-band 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-sub-band full-duplex symbols and sub-band full-duplex symbols.

[0176] For example, FIG55A 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 the present disclosure. Referring to FIG55A, the second transmission configuration indication state associated with control resource set #2 is configured with sub-band full-duplex resources. FIG55B is a schematic diagram illustrating the resource allocation of the control resource set according to an exemplary embodiment of the present disclosure. Referring to FIG55B, if the time offset between the scheduling downlink control information of control resource set #2 and the scheduling entity 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.

[0177] In one embodiment, the user equipment can obtain the quasi-co-bit assumption of the physical downlink shared channel from a first transmission configuration indication state indicated by the lowest code point of the transmission configuration indication status field applicable to the physical downlink shared channel in the partial bandwidth (BWP) of the scheduling cell. The lowest code point of the transmission configuration indication status field can be predefined / fixed / configured.

[0178] In one embodiment, the user equipment may assume that the quasi-co-occurrence assumption of the physical downlink shared channel used for scheduling derives from the transmission configuration indication status indicated by the lowest / predefined / fixed / configured code point in the transmission configuration indication status field applicable to the physical downlink shared channel within 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 identification code 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 in the transmission configuration indication status field is between code points associated with the sub-band full-duplex symbol.

[0179] For example, Figure 56 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 the present disclosure. Referring to Figure 56, if the time offset between the scheduling downlink control information of control resource set #1 and the scheduling entity downlink shared channel is less than a threshold, the user equipment may assume a quasi-co-location assumption for control resource set #1 based on a pre-determined rule using the preset transmission configuration indication state.

[0180] In one embodiment, the transmission configuration indication status field is associated with the same resource type as the time slot used for the receiving entity's downlink shared channel.

[0181] 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.

[0182] Figure 57 is a schematic diagram illustrating fields for indicating a transmission configuration indication state according to an exemplary embodiment of the present disclosure. Referring to Figure 57, during the initiation of the transmission configuration indication state in the MAC CE, field Ci may indicate a transmission configuration indication state group index. In the transmission configuration indication state fields of the downlink control information, the field for the transmission configuration indication state identifier i may indicate the transmission configuration indication state identified by the transmission configuration indication state identifier. The initiated transmission configuration indication state may be associated with at least one of the following: {sub-band full-duplex symbol, non-sub-band full-duplex symbol (none)}.

[0183] If field Ci is set to "0", the i-th transmission configuration indication status identifier may be associated with a non-sub-band full-duplex symbol, or used for the i-th transmission configuration indication status identifier received in the physical downlink shared channel within a non-sub-band full-duplex symbol. If field Ci is set to "1", the i-th transmission configuration indication status identifier may be associated with a sub-band full-duplex symbol, or used for the i-th transmission configuration indication status identifier received in the physical downlink shared channel within a sub-band full-duplex symbol. For example, fields C0 to C7 are set to "0", indicating that transmission configuration indication status identifiers 0,0 to 0,0 are associated with non-sub-band full-duplex symbols, respectively. Fields C8 to C15 are set to "1", indicating that transmission configuration indication status identifiers 1,0 to 1,7 are associated with sub-band full-duplex symbols, respectively. If the code point of the transmission configuration indication status field associated with a non-sub-band full-duplex symbol is, for example, "0", the transmission configuration indication status identification code indicates transmission configuration indication status identification code 0,0. If the code point of the transmission configuration indication status field associated with a sub-band full-duplex symbol is, for example, "7", the transmission configuration indication status identification code indicates transmission configuration indication status identification code 1,7.

[0184] In one embodiment, the user equipment can obtain its quasi-co-bit assumption for the scheduled entity downlink shared channel from the transmission configuration indication status indicated by the lowest / predefined / fixed / configured code point in the transmission configuration indication status field of the entity downlink shared channel in the startup BWP applicable to the scheduling cell. In one embodiment, the transmission configuration indication status field code point in the lowest / predefined / fixed / configured code point in the code point associated with the sub-band full-duplex symbol is used when (if or in some cases) the time offset between the scheduled entity downlink shared channel and the control resource set associated with the monitoring search space having the lowest control resource set identification code in the latest time slot associated with the sub-band full-duplex symbol is greater than a predefined / fixed / configured value.

[0185] For example, Figure 58 is a schematic diagram illustrating the allocation of control resource sets for a predetermined preset transmission configuration indication state according to an exemplary embodiment of the present disclosure. Referring to Figure 58, if the time offset between the scheduling downlink control information of control resource set #1 and the downlink shared channel of the scheduling entity 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 state identification code 1, 0, wherein the preset transmission configuration indication state can be indicated by the lowest code point of the transmission configuration indication state field.

[0186] Figure 59 is a schematic diagram illustrating fields for indicating transmission configuration indication states according to an exemplary embodiment of the present disclosure. Referring to Figure 59, during the initiation of the transmission configuration indication state of the MAC CE, field Ci may indicate the presence of an octet containing transmission configuration indication state identification codes i, 2. If this field is set to "1", the octet containing transmission configuration indication state identification codes i, 2 may exist. If this field is set to "0", the octet containing transmission configuration indication state identification codes i, 2 may not exist. The field containing transmission configuration indication state identification codes i, j may indicate the transmission configuration indication state identified by the TCI-State ID, where i may be the code point index of the downlink control information transmission configuration indication field, and the transmission configuration indication state identification codes i, j may represent 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 may be set to 0.

[0187] For example, field C0 is set to "1", and an octet containing transmission configuration indication status identification codes 0 and 2 is present. If the code point of the transmission configuration indication field in the downlink control information is "0", the first transmission configuration indication status associated with a non-sub-band full-duplex symbol is transmission configuration indication status identification code 0 and 1, and the second transmission configuration indication status associated with a sub-band full-duplex symbol is transmission configuration indication status identification code 0 and 2. If the code point of the transmission configuration indication field in the downlink control information is "1", the first transmission configuration indication status associated with a non-sub-band full-duplex symbol is transmission configuration indication status identification code 1 and 1, and the second transmission configuration indication status associated with a sub-band full-duplex symbol is transmission configuration indication status identification code 1 and 2.

[0188] In one embodiment, when 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 of the time slot used for the downlink shared channel of the receiving entity is applied.

[0189] In one embodiment, the user equipment may obtain its quasi-co-location assumption for the scheduled entity downlink shared channel from the transmission configuration indication state indicated by the lowest code point of the transmission configuration indication field of the entity downlink shared channel in the BWP applicable to the scheduling cell. In one embodiment, the time offset between the scheduled entity downlink shared channel and the control resource set associated with the monitored search space having the lowest control resource set identification code 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 identification code and / or apply the transmission configuration indication state associated with the sub-band full-duplex symbol.

[0190] In one embodiment, the user equipment may be configured with at least one transmission configuration indication state for SPS-entity downlink shared channel reception, such as a first transmission configuration indication state and a second transmission configuration indication state. 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 the SPS-entity downlink shared channel is in a non-subband full-duplex resource, the user equipment can receive the SPS-entity downlink shared channel through the first transmission configuration indication state. In another embodiment, when the SPS-entity downlink shared channel is in a subband full-duplex resource, the user equipment can receive the SPS-entity downlink shared channel through the second transmission configuration indication state.

[0191] Figure 60 is a schematic diagram illustrating an inappropriate transmission configuration indication state, according to an exemplary embodiment of this disclosure. Referring to Figure 60, a scheduling entity downlink shared channel using an inappropriate preset transmission configuration indication state (shared transmission configuration indication state) may suffer performance degradation. There may be no monitoring opportunities (MOs) in the time slots of the scheduling entity downlink shared channel, where the scheduling entity downlink shared channel is in a sub-band full-duplex symbol (or in non-sub-band full-duplex symbols respectively). The monitored search space with the lowest control resource set identification code 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.

[0192] Figure 61A is a schematic diagram illustrating a Media Access Control (MAC) Control Element (CE) field used to indicate a transmission configuration indication state, according to an exemplary embodiment of this disclosure. Referring to Figure 61A, in the initiation of a transmission configuration indication state in the MAC CE, field Ci may indicate a transmission configuration indication state group index. In the transmission configuration indication field of downlink control information, the transmission configuration indication state IDi field may indicate the transmission configuration indication state identified by the transmission configuration indication state ID. An initiated transmission configuration indication may be associated with at least one of the following: {sub-band full-duplex symbol, non-sub-band full-duplex symbol (none)}.

[0193] If field Ci is set to "0", the i-th transmission configuration indication status identifier may be associated with a non-sub-band full-duplex symbol, or used for the i-th transmission configuration indication status identifier received by the physical downlink shared channel in a non-sub-band full-duplex symbol. If field Ci is set to "1", the i-th transmission configuration indication status identifier may be associated with a sub-band full-duplex symbol, or used for the i-th transmission configuration indication status identifier received by the physical downlink shared channel in a sub-band full-duplex symbol. For example, fields C0 to C7 are set to "0", indicating that transmission configuration indication status identifiers 0,0 to 0,0 are associated with non-sub-band full-duplex symbols, respectively. Fields C8 to C15 are set to "1", indicating that transmission configuration indication status identifiers 1,0 to 1,7 are associated with sub-band full-duplex symbols, respectively. Figure 61B is a schematic diagram illustrating the downlink control information (DCI) transmission configuration indication fields, according to an exemplary embodiment of this disclosure. Referring to 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-sub-band full-duplex symbol is the transmission configuration indication state identification code 0,0, and the second transmission configuration indication state associated with the sub-band full-duplex symbol is the transmission configuration indication state identification code 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-sub-band full-duplex symbol is the transmission configuration indication state identification code 0,7, and the second transmission configuration indication state associated with the sub-band full-duplex symbol is the transmission configuration indication state identification code 1,7.

[0194] In one embodiment, when (if or in some cases) the user equipment transmits the last symbol of an entity 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 an entity downlink shared channel scheduled by downlink control information carrying a transmission configuration indication status indication, and when (if or in some cases) the indicated transmission configuration indication status differs from a previously indicated one, the indicated transmission configuration indication status with a transmission configuration indication status identifier may be applied starting from the first time slot, which may be at least a symbol following the last symbol of the entity uplink control channel (e.g., the time of beam application).

[0195] For example, FIG62A 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 the present disclosure. Referring to FIG62A, if the code point of the transmission configuration indication field is, for example, "1", the first transmission configuration indication state associated with a non-sub-band full-duplex symbol is transmission configuration indication state identification code 0,1, and the second transmission configuration indication state associated with a sub-band full-duplex symbol is transmission configuration indication state identification code 1,1. FIG62B is a timing diagram illustrating the common beam initiation of duplex operation according to an exemplary embodiment of the present disclosure. Referring to FIG62B, if the code point of the transmission configuration indication field of downlink control information #1 is "1", the transmission configuration indication state identification codes 0,1 associated with a non-sub-band full-duplex symbol and 1,1 associated with a sub-band full-duplex symbol will be applied after beam application using transmission configuration indication state identification codes 0,0 and 1,0.

[0196] In one embodiment, when (if or under certain circumstances) the offset between the reception of downlink control information and the corresponding entity's downlink shared channel is less than a threshold:

[0197] When the indicated transmission configuration indication state is associated with the entity layer cell identification code of the serving cell (if or under certain circumstances), the indicated transmission configuration indication state associated with the sub-band full-duplex symbol (or non-sub-band full-duplex symbol, respectively) can be applied to entity downlink shared channel reception on the sub-band full-duplex symbol (or non-sub-band full-duplex symbol, respectively).

[0198] For example, Figure 63 is a schematic diagram illustrating the selection of a transmission configuration indication state associated with the same resource type according to an exemplary embodiment of this disclosure. Referring to Figure 63, transmission configuration indication state #0 associated with the physical layer cell identifier of the serving cell is associated with a non-sub-band full-duplex symbol, while transmission configuration indication state #1 associated with the physical layer cell identifier of the same serving cell is associated with a sub-band 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 transmission configuration indication state #1 associated with the sub-band full-duplex symbol to physical downlink shared channel reception on the sub-band full-duplex symbol.

[0199] In one embodiment, when (if or under certain circumstances) the semi-persistent scheduling entity downlink shared channel is in a non-sub-band full-duplex resource, the user equipment can receive the semi-persistent scheduling entity downlink shared channel through the transmission configuration indication state of the application associated with the non-sub-band full-duplex resource. In another embodiment, when (if or under certain circumstances) the semi-persistent scheduling entity downlink shared channel is in a sub-band full-duplex resource, the user equipment can receive the semi-persistent scheduling entity downlink shared channel through the transmission configuration indication state of the application associated with the sub-band full-duplex resource.

[0200] In one embodiment, when (if or under certain circumstances) the offset between the reception of downlink control information and the corresponding entity's downlink shared channel is less than a threshold: When (if or under certain circumstances) a transmission configuration indication state is associated with an entity layer cell identifier that is different from the serving cell and the transmission configuration indication state is associated with a sub-band full-duplex symbol, The transmission configuration indication state associated with a non-sub-band full-duplex symbol can be applied to physical downlink shared channel reception on the non-sub-band full-duplex symbol; and / or User equipment may not expect the physical downlink shared channel to be scheduled in the sub-band full-duplex symbol.

[0201] For example, Figure 64 is a schematic diagram illustrating the selection of a transmission configuration indication state associated with the same resource type according to an exemplary embodiment of this disclosure. Referring to Figure 64, the transmission configuration indication state #0 associated with the serving cell is associated with a non-sub-band full-duplex symbol, while the transmission configuration indication state #1 associated with the non-serving cell is associated with a sub-band 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 may apply the transmission configuration indication state #0 associated with the non-sub-band full-duplex symbol to the physical downlink shared channel reception on the non-sub-band full-duplex symbol, without expecting the physical downlink shared channel to be scheduled in the sub-band full-duplex symbol.

[0202] In one embodiment, when (if or under certain circumstances) the offset between the reception of downlink control information and the corresponding entity's downlink shared channel is less than a threshold: When (if or under certain circumstances) a transmission configuration indication state is associated with an entity layer cell identifier that is different from the serving cell and the transmission configuration indication state is associated with a sub-band full-duplex symbol, The transmission configuration indication state associated with a non-sub-band full-duplex symbol can be applied to physical downlink shared channel reception on the non-sub-band full-duplex symbol; and / or User equipment may not expect the physical downlink shared channel to be scheduled in the sub-band full-duplex symbol.

[0203] For example, Figure 65 is a schematic diagram illustrating the selection of transmission configuration indication states associated with the same resource type according to an exemplary embodiment of this disclosure. Referring to Figure 65, transmission configuration indication state #0 associated with the serving cell is associated with a non-subband full-duplex symbol, while transmission configuration indication state #1 associated with the 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 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, without expecting the physical downlink shared channel to be scheduled in a non-subband full-duplex symbol.

[0204] In one embodiment, when (if or under certain circumstances) the offset between the reception of downlink control information and the corresponding entity downlink shared channel is less than a threshold: When (if or under certain circumstances) a transmission configuration indication state is associated with an entity layer cell identifier that is different from the serving cell and the transmission configuration indication state is associated with a sub-band full-duplex symbol, The transmission configuration indication state associated with the sub-band full-duplex symbol (or the non-sub-band full-duplex symbol) can be applied to the physical downlink shared channel reception on the sub-band full-duplex symbol (or the non-sub-band full-duplex symbol).

Referring to Figure 68, the field "Fm" indicates the activation / deactivation status of the frequency position outside the m-th downlink subband. The field of the channel status information-reference signal resource configuration identifier indicates the mapping between the activated frequency position outside the downlink subband and the channel status information-reference signal resource. In one embodiment, when (if or under certain circumstances) the field of the channel status information-reference signal resource configuration identifier is set to all "1", the activation / deactivation status of the frequency position outside the m-th downlink subband can be applied to all channel status information-reference signal resources.

[0222] Figure 76 is a schematic diagram illustrating the non-contiguous channel state information-reference signal resource allocation of a channel state information-reference signal resource according to an exemplary embodiment of the present disclosure. Referring to Figure 76, there may be three additional parameters in the channel state information-reference signal resource configuration. These three additional parameters are "2ndstartingRB", "2ndnrofRBs", and "3rdnrofRBs", where "startingRB" is the resource block (RB) at which this channel state information resource begins relative to shared resource block #0, and "nrofRBs" is the number of resource blocks (RBs) that this channel state information resource spans.

[0223] Figure 77 is a schematic diagram illustrating two connected, non-contiguous channel state information-reference signal resources according to an exemplary embodiment of this disclosure. Referring to Figure 77, there may be two additional parameters in the channel state information-reference signal resource configuration. These two additional parameters are "3rd starting RB" and "3rd number of RBs", where "starting RB" is the resource block (RB) at which this channel state information resource begins relative to shared resource block #0, and "number of RBs" is the number of resource blocks (RBs) that this channel state information resource spans.

[0224] Figure 78 is a schematic diagram illustrating the sub-band full-duplex and non-sub-band full-duplex channel status information-reference signal configuration according to an exemplary embodiment of the present disclosure. Referring to Figure 78, option 2-1 "Discontinuous Channel Status Information-Reference Signal Resource Allocation" in option 2 of parameter "nzp-CSI-RS-Resource" indicates a "first resource mapping" for the non-sub-band full-duplex type and a "second resource mapping" for the sub-band full-duplex type in the conventional configuration.

[0226] Figure 80 is a schematic diagram illustrating the channel measurement time restriction according to an exemplary embodiment of this disclosure. Referring to Figure 80, a situation may arise when the higher-level parameter `timeRestrictionForChannelMeasurements` in the channel status information reporting configuration is set to "Configured" (if or under certain circumstances). If there are frequency resources for channel status information—reference signal resources—associated with full-duplex channel status information outside the downlink subband, a question may arise regarding whether / how to report the subband PMI / CQI of the frequency resources outside the downlink subband.

[0227] Figure 81 is a schematic diagram illustrating the channel measurement time restriction according to an exemplary embodiment of the present disclosure. Referring to Figure 81, when (if or under certain circumstances) the higher-level parameter timeRestrictionForChannelMeasurements in the channel status information reporting configuration is set to "Configured", the user equipment may derive the channel measurements used to calculate the channel status information reported in uplink time slot n based solely on the most recent sub-band full-duplex channel status information-reference signal and the non-sub-band full-duplex channel status information-reference signal. For example, channel status information reporting is performed based on the most recent channel status information-reference signal associated with sub-band full-duplex and the channel status information-reference signal associated with non-sub-band full-duplex.

[0228] Figure 82 is a schematic diagram illustrating channel measurement resource allocation according to an exemplary embodiment of this disclosure. Referring to Figure 81, a situation may occur when (if or under certain circumstances) the user equipment is configured with a channel status information reporting configuration where the higher-level parameter reportQuantity is set to "cri-RI-PMI-CQI". When (if or under certain circumstances) the most recent channel status information reference signal used for channel status information reporting is a sub-band full-duplex channel status information reference signal; and / or When (if or under certain circumstances) the channel status information from the sub-band full-duplex channel status information-reference signal and the non-sub-band full-duplex channel status information-reference signal may have the same CRI and RI values. For example, if the channel status information-reference signal associated with sub-band full-duplex and the channel status information-reference signal associated with non-sub-band full-duplex have the same CRI and RI values, then channel status information reporting is performed for the most recent channel status information-reference signal associated with sub-band full-duplex and the channel status information-reference signal associated with non-sub-band full-duplex, as shown in Figure 81. Sub-band PMI / CQI may come from the measurement results of the channel status information-reference signal associated with sub-band full-duplex in downlink sub-band frequency resources. Sub-band PMI / CQI may come from the measurement results of the channel status information-reference signal associated with non-sub-band full-duplex in downlink out-of-sub-band frequency resources.

[0229] In one embodiment, when the user equipment is configured with the higher-level parameter reportQuantity set to "cri-RI-PMI-CQI" for channel status information reporting (if or under certain circumstances), a situation may occur where... When (if or under certain circumstances) the most recent channel status information reference signal used for channel status information reporting is a sub-band full-duplex channel status information reference signal; When (if or under certain circumstances) the channel status information from the sub-band full-duplex channel status information-reference signal and the non-sub-band full-duplex channel status information-reference signal may have the same CRI and RI values; When the higher-level parameter cqi-BitsPerSubband in the channel status information report configuration is not configured (if or under certain circumstances), for each sub-band index s of the downlink out-of-subband frequency resource. Taking Figure 82 as an example, for the sub-band PMI / CQI derived from the measurement results of the channel status information-reference signal associated with non-sub-band full-duplex in the downlink out-of-subband frequency resource, the sub-band offset level (s) = sub-band CQI index (s) - wideband CQI index, where the sub-band CQI index is configured based on the measurement results of the non-sub-band full-duplex channel status information-reference signal, and the wideband CQI index is configured based on the measurement results of the sub-band full-duplex channel status information-reference signal.

[0230] Figure 83 is a schematic diagram illustrating a subband precoding matrix indication (PMI) / channel quality indication (CQI) report according to an exemplary embodiment of this disclosure. Referring to Figure 83, a portion of the bandwidth may, for example, be 24 physical resource blocks, and the subband size NPRB SB may, for example, be 4 physical resource blocks. The start of the portion of the bandwidth may, for example, be the second physical resource block. There may be seven subbands A0, A1, A2, A3, A4, A5, A6 allocated for PMI / CQI reporting. The size of the first subband A0 is... .if Then the size of the final subband A6 is , or if Then the size of the final subband A6 is .

[0231] Table (1) shows the mapping from subband differential CQI values ​​to offset levels. Table (1) Subband difference CQI value Offset level 0 0 1 1 2 ≥ 2 3 ≤-1 In one embodiment, regarding the Channel Quality Indicator (CQI), when the higher-level parameter cqi-BitsPerSubband in the Channel Status Information Report Configuration (CSI-ReportConfig) is not configured (if or under certain circumstances), a 2-bit sub-band differential CQI can be defined for each sub-band index s as follows: Subband Offset Level = Subband CQI Index - Wideband CQI Index; and / or The mapping from 2-bit subband differential CQI values ​​to offset levels is shown in the table.

[0232] In one embodiment, there may be a situation where, (if or under certain circumstances) the user equipment is configured with a channel status information reporting configuration, its high-level parameter `reportQuantity` is set to 'cri-RI-PMI-CQI': When (if or under certain circumstances) the channel status information reference signal most recently used for channel status information reporting is a sub-band full-duplex channel status information reference signal; When (if or under certain circumstances) the channel status information from the sub-band full-duplex channel status information-reference signal and the non-sub-band full-duplex channel status information-reference signal may have different CRI and / or RI values; and / or When (if or under what circumstances) the high-level parameter cqi-BitsPerSubband in the channel status information report configuration is configured.

[0233] Using Figure 81 as an example, if there are different CRI and / or RI values ​​between the channel status information reference signal associated with sub-band full-duplex and the channel status information reference signal associated with non-sub-band full-duplex, then the channel status information report for the most recent channel status information reference signal associated with both sub-band full-duplex and non-sub-band full-duplex is executed. It should be noted that the channel status information from the non-sub-band full-duplex channel status information reference signal may be outdated. Therefore, this channel status information may not be useful for downlink scheduling in the base station network. Figure 84 is a schematic diagram illustrating the allocation of channel measurement resources according to an exemplary embodiment of this disclosure. Referring to Figure 84, in frequency resources outside the downlink subband, the subband CQI index may be set to "0".

[0234] In one embodiment, there may be a situation where, (if or under certain circumstances) the user equipment is configured with a channel status information reporting configuration, its high-level parameter `reportQuantity` is set to 'cri-RI-PMI-CQI': When (if or under certain circumstances) the channel status information reference signal most recently used for channel status information reporting is a sub-band full-duplex channel status information reference signal; When (if or under certain circumstances) the channel status information from the sub-band full-duplex channel status information-reference signal and the non-sub-band full-duplex channel status information-reference signal may have different CRI and / or RI values; and / or When (if or under certain circumstances) the high-level parameter cqi-BitsPerSubband in the channel status information report configuration is not configured.

[0235] For example, Figure 85 is a schematic diagram illustrating the allocation of channel measurement resources according to an exemplary embodiment of this disclosure. Referring to Figure 85, in frequency resources outside the downlink subband, the subband differential CQI value may be set to "3". Furthermore, Table (2) is a mapping of subband differential CQI values ​​to offset levels. Table (2) Subband difference CQI value Offset level 0 0 1 1 2 ≥ 2 3 ≤-1

[0236] In one embodiment, there may be a situation where, (if or under certain circumstances) the user equipment is configured with a channel status information reporting configuration, its high-level parameter `reportQuantity` is set to 'cri-RI-PMI-CQI': When (if or under certain circumstances) the channel status information reference signal most recently used for channel status information reporting is a non-sub-band full-duplex channel status information reference signal.

[0237] For example, Figure 86 is a schematic diagram illustrating the channel measurement time limitation according to an exemplary embodiment of this disclosure. Referring to Figure 86, the most recent channel state information-reference signal associated with non-sub-band full-duplex is used for channel state information reporting, but the most recent channel state information-reference signal associated with sub-band full-duplex is not used for channel state information reporting. Note that in this case, conventional behavior is followed, i.e., the latest channel state information is based on the most recent channel state information-reference signal.

[0238] Furthermore, Figure 87 is a schematic diagram illustrating the allocation of channel measurement resources according to an exemplary embodiment of this disclosure. Referring to Figure 87, the sub-band PMI / CQI may originate from the measurement results of channel state information-reference signals associated with non-sub-band full-duplex frequency resources within the downlink sub-band.

[0239] Figure 88 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. Referring to Figure 88, there may be a situation where (if or under certain circumstances) the entity downlink shared channel carries an SP CSI-RS (Semi-Persistent CSI-RS) start command or a P CSI-RS (Periodic CSI-RS) resource reconfiguration. A potential issue is whether or how to report the sub-band PMI / CQI of frequency resources outside the downlink sub-band.

[0240] Figure 89 is a schematic diagram illustrating the allocation of channel status information reporting resources according to an exemplary embodiment of this disclosure. Referring to Figure 89, regarding the channel status information-reference signal associated with sub-band full-duplex, in frequency resources outside the downlink sub-band, the sub-band CQI index may be set to "0" or the sub-band differential CQI value may be set to "3". The sub-band PMI / CQI may originate from the measurement results of the sub-band full-duplex channel status information-reference signal in frequency resources within the downlink sub-band.

[0241] Figure 90 is a schematic diagram illustrating the sub-band full-duplex and non-sub-band full-duplex channel status information-reference signal configuration according to an exemplary embodiment of the present disclosure. Referring to Figure 90, the parameter "nzp-CSI-RS-Resource" indicates "first resourceMapping", where qcl-InfoPeriodicCSI-RS is the first transmission configuration indication status identification code configuration for non-sub-band full-duplex type in the conventional configuration, and "second resourceMapping", where qcl-InfoPeriodicCSI-RS is the first or second transmission configuration indication status identification code configuration for sub-band full-duplex type.

[0242] In one embodiment, only allocated entity resource blocks within downlink available entity resource blocks are considered valid for entity downlink shared channels.

[0243] In one embodiment, allocated entity resource blocks that fall outside of downlink available entity resource blocks are considered invalid. In some embodiments, allocated entity resource blocks that fall outside of downlink available entity resource blocks should not be used.

[0244] In one embodiment, the user equipment can receive channel status information report configuration, wherein for channel status information reporting sub-bands 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 can report channel status information according to the channel status information report configuration.

[0245] In one embodiment, the user equipment can receive a channel status information report configuration, wherein the channel status information report configuration is associated with channel status information-reference signal resources. For channel status information-reference signal resources overlapping with the boundaries of a full-duplex sub-band, only the channel status information-reference signal frequency resources within the downlink available physical resource block are valid. The user equipment can report channel status information according to the channel status information report configuration.

[0246] In one embodiment, the user equipment can receive a channel status information report configuration, wherein the channel status information report configuration is associated with channel status information-reference signal resources, and the channel status information-reference signal mapping applies only to channel status information-reference signal resources within downlink available entity resource blocks. The user equipment can report channel status information according to the channel status information report configuration.

[0247] In one embodiment, the user equipment may receive a channel status information report configuration, wherein the channel status information report configuration is associated with channel status information-reference signal resources, and the channel status information-reference signal resources mapped to resource blocks outside the downlink available entity resource blocks are traversed. The user equipment may report channel status information according to the channel status information report configuration.

[0248] Figure 91 is a schematic diagram illustrating a sub-band channel status information report for each sub-band full-duplex channel status information-reference signal according to an exemplary embodiment of this disclosure. Referring to Figure 91, there may be an example of a channel status information report where the most recent channel status information-reference signal associated with sub-band full-duplex and the channel status information-reference signal associated with non-sub-band full-duplex are used for channel status information reporting. To reduce channel status information overhead, the user equipment may not need to report sub-band precoding matrix indications / channel quality indications for downlink sub-band external frequency resources. For example, the "subbands6" of the first CSI-ReportingBand of the channel status information-reference signal associated with non-sub-band full-duplex is set to "111111", while the "subbands6" of the second CSI-ReportingBand of the channel status information-reference signal associated with sub-band full-duplex is set to "110011", where "0" corresponds to frequency resources outside the downlink sub-band.

[0249] There may be multiple channel status information selection indications. For example, Figures 92A to 92C are schematic diagrams illustrating channel status information selection indications according to an exemplary embodiment of this disclosure. Referring to Figure 92A, a channel status information reporting instance may be channel status information for a non-sub-band full-duplex channel status information-reference signal and channel status information for a sub-band full-duplex channel status information-reference signal. Referring to Figure 92B, when the channel status information for a non-sub-band full-duplex channel status information-reference signal may not be reported because it has not been updated, a channel status information reporting instance may be channel status information for a sub-band full-duplex channel status information-reference signal. Referring to Figure 92C, when the channel status information for a sub-band full-duplex channel status information-reference signal may not be reported because it has not been updated, a channel status information reporting instance may be channel status information for a non-sub-band full-duplex channel status information-reference signal. However, in these cases, it may be problematic how the base station network knows which one or two channel status information to report.

[0250] Table (3) shows the channel status information selection instructions: Table (3) Channel status information selection indicator value illustrate 0 Channel status information for both non-sub-band full-duplex CSI-RS and sub-band full-duplex CSI-RS High priority: Channel status information of non-subband full-duplex CSI-RS Low priority: Channel status information of sub-band full-duplex CSI-RS 1 Channel status information for both non-sub-band full-duplex CSI-RS and sub-band full-duplex CSI-RS High priority: Channel status information of sub-band full-duplex CSI-RS Low priority: Channel status information of non-subband full-duplex CSI-RS 2 Non-subband full-duplex CSI-RS 3 Sub-band full-duplex CSI-RS

For example, Figures 93A and 93B are schematic diagrams illustrating a channel status information selection indication according to an exemplary embodiment of the present disclosure. Referring to Figure 93A, if the channel status information selection indication value is set to "3", the channel status information of the non-sub-band full-duplex channel status information-reference signal will be reported, but the channel status information of the sub-band full-duplex channel status information-reference signal will not be reported because it has not been updated. Referring to Figure 93B, if the channel status information selection indication value is set to "2", the channel status information of the sub-band full-duplex channel status information-reference signal will be reported, but the channel status information of the non-sub-band full-duplex channel status information-reference signal will not be reported because it has not been updated.

[0252] In one embodiment, there may be a situation where (if or in this case) the user equipment is configured to report the channel status information of both the non-sub-band full-duplex channel status information-reference signal and the sub-band full-duplex channel status information-reference signal. For example, Figures 94A and 94B are schematic diagrams illustrating a channel status information selection indication according to an exemplary embodiment of the present disclosure. Referring to Figure 94A, if the channel status information selection indication value is set to "1", the channel status information of the sub-band full-duplex channel status information-reference signal will be reported, but the channel status information of the non-sub-band full-duplex channel status information-reference signal will not be reported because it has not been updated. Referring to Figure 94B, if the channel status information selection indication value is set to "0", the channel status information of the non-sub-band full-duplex channel status information-reference signal will be reported, but the channel status information of the sub-band full-duplex channel status information-reference signal will not be reported because it has not been updated.

Referring to Figure 95, if there is a channel status information reference signal associated with non-sub-band full-duplex, the channel status information of the non-sub-band full-duplex channel status information reference signal may be discarded or expired due to its low priority. If there is a channel status information reference signal associated with sub-band full-duplex and the channel status information selection indication value is set to "3", the channel status information of the full-duplex channel status information reference signal may be reported.

In one embodiment, when (if or in this case) the channel status information selection indicator is not configured: User equipment can report two channel status information: non-subband full-duplex channel status information - reference signal and subband full-duplex channel status information - reference signal, and / or User equipment can preset the priority of channel status information, for example, High priority: Channel status information of non-sub-band full-duplex channel status information - reference signal (or sub-band full-duplex channel status information - reference signal); Low priority: Channel status information of sub-band full-duplex channel status information - reference signal (or non-sub-band full-duplex channel status information - reference signal).

[0255] In one embodiment, for sub-band full-duplex channel status information reporting, the user equipment may be configured to at least one of the following: Both: Non-sub-band full-duplex channel status information - reference signal and sub-band full-duplex channel status information - reference signal channel status information; dynamic: Non-sub-band full-duplex channel status information - reference signal and / or sub-band full-duplex channel status information - reference signal channel status information. In one embodiment, the user equipment may be configured to prioritize channel status information as follows: Non-subband full-duplex channel status information - the channel status information of the reference signal can have higher priority; Sub-band full-duplex channel status information - the channel status information of the reference signal can have higher priority; None: The priority of channel status information is determined by the user equipment.

The channel status information selection indicator may not be displayed. 0-bit overhead Channel status information selection indicator 2-bit overhead Sub-band full-duplex channel status information - the reference signal may have higher priority. The channel status information selection indicator may not be displayed. 0-bit overhead Channel status information selection indicator 2-bit overhead none Channel status information selection indicator 1-bit overhead Channel status information selection indicator 2-bit overhead
