Abstract
Description
Technical Field
[0001] This invention relates to a wireless communication technology, and more specifically, to a communication operation method and a user device. Background Technology
[0002] With the evolution of wireless communication technologies such as 5G New Radio (NR), the demand for network performance and energy efficiency is increasing. In the Carrier Aggregation (CA) architecture, user equipment in the RRC_CONNECTED state can be configured with multiple serving cells, including the primary cell (PCell) and one or more secondary cells (SCell).
[0003] In existing communication systems, the Synchronization Signal / Physical Broadcast Channel Block (SSB) is crucial for subcell management, such as for subcell activation, time / frequency synchronization, and beam management. Traditional SSBs are typically transmitted at a fixed period (e.g., between 5 milliseconds and 160 milliseconds). Furthermore, user equipment (UEs) must report Channel State Information (CSI) based on configuration data from the network to assist the base station in scheduling and link adaptation. For semi-persistent scheduling (SPS) CSI reporting, explicit enable and disable commands are usually required to control the start and end times of the reporting procedure.
[0004] However, to reduce network operating costs and minimize environmental impact, Network Energy Savings (NES) has become an important development direction. In recent years, concepts related to Service Shields (SSBs) have been proposed for application in scenarios with low traffic loads or low user equipment mobility. In such architectures, the coordination between SSB reception and the corresponding CSI measurement and reporting mechanisms remains a crucial issue that needs to be addressed in related technologies.

[0158] First, let me introduce some related technologies.
[0159] Figure 1 This is a schematic diagram illustrating SPS CSI reporting according to an embodiment of the present invention. (Refer to...) Figure 1 The transmission of SPS CSI reports typically involves an enable phase and a disable phase. Upon receiving an SPS CSI report enable instruction, the User Equipment (UE) begins executing SPS CSI reports. Subsequently, the UE periodically transmits CSI reports. The UE only stops executing SPS CSI reports upon receiving an explicit SPS CSI report disable instruction.
[0160] When the expected traffic load on a SCell does not exhibit frequent bursts (low SCell activation rate) and user equipment mobility is low (low SCell addition / modification rate), frequent SSB-based measurements are unnecessary, and the SCell's SSB can be disabled. SSB can then be reactivated when needed. For Rel-19 Network Energy Saving (NES), Radio Access Networks Working Group 1 (RAN1) specifies SSB-less SCell operation for inter-band carrier aggregation (CA) and proposes on-demand SSB SCell operation. On-demand SSB transmission can be used by the UE for at least: SCell time / frequency synchronization and beam management for SCell activation.
[0161] Figure 2 This is a schematic diagram illustrating on-demand SSB according to an embodiment of the present invention. (Refer to...) Figure 2Compared to "Always-on SSB," which transmits periodically (e.g., with long periods) to maintain the radio link, "On-demand SSB (OD-SSB)" is transmitted only when necessary (e.g., for SCell activation) and typically has shorter periods. Case #1 is a scenario where there is no Always-on SSB on the cell. The SCell transmits an SSB only when triggered (on demand). Once triggered, OD-SSB transmissions can be periodic within a period. Case #2 is a scenario where Always-on SSB is transmitted periodically on the cell. The cell maintains Always-on SSB (e.g., with longer periods) for basic link maintenance and activates OD-SSB (e.g., with shorter periods) when active communication or measurement is required, such as SCell activation. It should be noted that when the expected traffic load on the SCell is not frequently bursty and UE mobility is low, SSB-based measurements do not need to be performed frequently, and the SCell's SSB can be turned off.
[0162] For cells that support SCell operations for OD-SSB, at least if the RRC also configures and enables SCell and provides OD-SSB configuration, RRC-based signaling can be used to indicate OD-SSB transmission on the cell; in addition, MAC CE-based signaling can also be used to indicate OD-SSB transmission on the cell.
[0163] For cells that support SCell operations with OD-SSB, from the UE's perspective, at least the following options for disabling OD-SSB transmission are supported.
[0164] Figure 3A This is a schematic diagram illustrating the first deactivation option for OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 3A The first deactivation option is an explicit instruction mechanism, whereby the network sends a specific command to terminate SSB transmission. This mechanism gives the network control over the duration of SSB bursts. The UE continuously monitors SSBs after OD-SSB is enabled until it receives an explicit deactivation signal. For example... Figure 3A As shown, the process includes:
[0165] Instruction: The network transmits an instruction (e.g., OD-SSB activation) at point A to begin the transmission of that OD-SSB.
[0166] Disabling (e.g., via MAC CE): Subsequently, the network transmits a MAC-CE to disable the OD-SSB. The UE then stops receiving the OD-SSB after processing this instruction.
[0167] In one embodiment, the UE may determine a first number of SSB bursts and stop receiving the first transmission of the first SSB until the first number of SSB bursts are received.
[0168] In one embodiment, the UE may determine a first number of SSB bursts indicated or provided by DCI, RRC configuration, or MAC-CE.
[0169] Figure 3B This is a schematic diagram illustrating a second deactivation option for OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 3B The second deactivation option is an implicit termination mechanism based on the configured number of bursts. A limited number (N) of SSB bursts will be transmitted. Once N bursts are received or the corresponding time period expires, the UE stops receiving SSB bursts. Figure 3B As shown, the process includes:
[0170] Instruction: Enable OD-SSB on the network.
[0171] N OD-SSB bursts (e.g., N equals 4): Configure to specify N bursts (e.g., N=4). The UE precisely monitors 4 bursts, then stops monitoring.
[0172] It should be noted that the CSI reporting procedure for OD-SSB is still open to further discussion. For example, for CSI reporting similar to SPS, a deactivation command may not be necessary.
[0173] Figure 4 This is a schematic diagram illustrating a communication system 100 according to an embodiment of the present invention. (Refer to...) Figure 4 The communication system 100 (e.g., a Long Term Evolution (LTE) system, an LTE-Advanced (LTE-A) system, an Advanced Professional LTE system, a 5G New Radio Access Network (RAN), or a 6G Radio Access Network) typically includes at least one network device 110, at least one user equipment (UE) 120, and one or more optional network components for providing connectivity to the network. The UE 120 communicates with the network (e.g., a Core Network (CN), an Evolved Packet Core (EPC) network, an Evolved Universal Terrestrial Radio Access Network (E-UTRAN), a 5G Core (5GC), or the Internet) through the radio access network established by one or more network devices 110.
[0174] Network device 110 (which may be referred to as a base station) can be used to provide communication services according to at least one of the following radio access technologies (RATs): Worldwide Interoperability for Microwave Access (WiMAX), Global System for Mobile Communications (GSM, commonly referred to as 2G), GSM Enhanced Data rates for GSM Evolution Radio Access Network (GERAN), General Packet Radio Service (GPRS), Universal Mobile Telecommunication System (UMTS, commonly referred to as 3G) based on wideband-code division multiple access (W-CDMA), high-speed packet access (HSPA), LTE, Advanced LTE, Evolved LTE (eLTE, e.g., LTE connected to a 5G core), New Radio (commonly referred to as 5G), and / or Advanced Specialized LTE. However, the scope of the invention should not be limited to the above-mentioned protocols.
[0175] Network device 110 may include, but is not limited to: a node B (NB) in UMTS, an evolved node B (eNB) in LTE or LTE-A, a radio network controller (RNC) in UMTS, a base station controller (BSC) such as in GSM / GSM Enhanced Data rates for GSM Evolution, EDGE Radio Access Network (GERAN), a next-generation eNB (ng-eNB) connected to an Evolved Universal Terrestrial Radio Access (E-UTRA) base station connected to 5GC, a next-generation node B (gNB) such as in a 5G Access Network (5G-AN), and any other means capable of controlling wireless communication and managing intracellular radio resources. Network device 110 may be connected to serve one or more UEs to the network via a radio interface.
[0176] Network device 110 (or base station) is operable to provide wireless coverage to a specific geographic area using multiple cells included in a radio access network. Network device 110 can support cell operation. Each cell is operable to provide service to at least one UE within its wireless coverage area. Specifically, each cell (generally referred to as the serving cell) can provide service to one or more UEs 120 within its wireless coverage area (e.g., each cell schedules downlink and optional uplink resources for at least one UE 120 within its wireless coverage area for downlink and optional uplink packet transmissions). Network device 110 can communicate with one or more UEs 120 in a wireless communication system via multiple cells. It should be noted that, for the uplink, UE 120 is the transmitter performing uplink transmission, and network device 110 is the receiver performing uplink reception. For the downlink, UE 120 is the receiver performing downlink reception, and network device 110 is the transmitter performing downlink transmission.
[0177] Network device 120 may include network node NN and one or more transmission reception points (TRPs).
[0178] It should be noted that in this invention, UE 120 may be, but is not limited to, a mobile station, mobile terminal, device, or user communication wireless terminal. For example, the user equipment may be a portable wireless device, including but not limited to mobile phones, tablet computers, wearable devices, sensors, vehicles, or personal digital assistants (PDAs) with wireless communication capabilities. UE 120 is used to receive and transmit signals to one or more cells in the radio access network via the air interface.
[0179] It should be understood that the terms "system" and "network" used in this invention are generally used interchangeably. The term "and / or" in this invention describes the relationship between related objects only, meaning that three relationships can exist. For example, A and / or B can mean three cases: only A exists, A and B exist simultaneously, or only B exists. Furthermore, the character " / " in this invention generally indicates that the related objects are in an "or" relationship.
[0180] To facilitate understanding of the technical solutions of the embodiments of the present invention, the following describes the technical concepts related to the embodiments of the present invention.
[0181] Figure 5 This is a flowchart illustrating a communication operation method according to an embodiment of the present invention. The method can be executed by UE 120. (Refer to...) Figure 5 In step S510, UE 120 receives a first signaling for enabling a first transmission of the Synchronization Signal / Physical Broadcast Channel Block (SSB). Specifically, the first signaling is a control signaling / message for triggering SSB transmission, such as an OD-SSB burst. In one embodiment, the first signaling may be an enable instruction for a first SSB (e.g., an On-demand SSB, OD-SSB). The first signaling may trigger the transmission of an SSB burst on the SCell. In one embodiment, the first signaling is indicated or provided by Downlink Control Information (DCI), RRC configuration, or Medium Access Control-Control Element (MAC-CE). For example, UE 120 receives a MAC-CE indicating the enabling of OD-SSB.
[0182] In step S520, UE 120 receives the first transmission of the first SSB according to the first signaling. Specifically, upon receiving the first signaling, UE 120 determines the radio resources for the first SSB and begins receiving. This allows UE 120 to perform synchronization or measurement on the OD-SSB. In one embodiment, the first SSB may be an OD-SSB burst. Upon receiving the instruction, UE 120 begins monitoring the configured resources.
[0183] In one embodiment, the CSI report for the OD-SSB can be configured as "periodic," "semi-persistent scheduling (SPS)," "SPS-like," or "aperiodic." In one embodiment, if the OD-SSB's CSI report is configured as "periodic," the corresponding CSI report for the OD-SSB can be reported on a first uplink channel (e.g., PUCCH). In one embodiment, if the OD-SSB's CSI report is configured as "semi-persistent scheduling" or "semi-persistent scheduling," the corresponding CSI report for the OD-SSB can be reported on a second uplink channel (e.g., PUCCH or PUSCH). In one embodiment, if the OD-SSB's CSI report is configured as "aperiodic," the corresponding CSI report for the OD-SSB can be reported on a third uplink channel (e.g., PUSCH).
[0184] In one embodiment, the instruction to enable CSI reporting for OD-SSB may be:
[0185] The same as the OD-SSB enable command, or
[0186] Additional instructions following the OD-SSB enable instruction transmission.
[0187] In one embodiment, if the OD-SSB enable command is transmitted via MAC-CE, the CSI-reported enable command can be transmitted after a delay of ΔT following the ACK transmission of the OD-SSB enable command.
[0188] For example, Figure 6 A schematic diagram illustrating the OD-SSB activation procedure according to an embodiment of the present invention. (Refer to...) Figure 6 The process begins with the activation of OD-SSB. Time point A is defined as the start time of the first time slot containing the SSB index of the first actual transmission within the first "possible" OD-SSB burst. The CSI-reported activation instruction (e.g., via MAC-CE or DCI) will not occur until at least ΔT delay after UE120 transmits a signaling (e.g., ACK) to network device 110 (e.g., gNB) in response to the activation of OD-SSB transmission.
[0189] In one embodiment, the OD-SSB activation command may be a CSI reporting activation command. For example, the OD-SSB activation process begins with an OD-SSB activation command. The OD-SSB activation command further indicates a CSI reporting activation command. After UE 120 transmits this signaling (e.g., ACK) to network device 110 (e.g., gNB), UE 120 begins reporting CSI corresponding to the received OD-SSB burst. That is, OD-SSB and CSI reporting require only a shared activation command.
[0190] In one embodiment, UE 120 may receive a second signaling for disabling a first transmission of a first SSB, and stop receiving the first transmission of the first SSB according to the second signaling.
[0191] In one embodiment, the second signaling is indicated or provided by DCI, RRC configuration, or MAC-CE.
[0192] In one embodiment, the deactivation command for OD-SSB CSI reporting may not be necessary, since from the UE's point of view, at least the following options are supported to deactivate OD-SSB transmission.
[0193] Option 1: Provide an explicit deactivation indication for OD-SSB via MAC-CE for OD-SSB transmission indication;
[0194] Option 2: After indicating OD-SSB, configure / indicate to transmit N OD-SSB bursts.
[0195] by Figure 6 As an example, the configuration indicates 4 OD-SSB bursts. CSI reporting is disabled after 4 CSI reports have been transmitted.
[0196] Figure 7 This is a schematic diagram illustrating the CSI report of an OD-SSB without a deactivation instruction, according to an embodiment of the present invention. (Refer to...) Figure 7 This method involves an implicit deactivation of CSI reporting. This scenario corresponds to "semi-persistent scheduling (SPS-like)" CSI reporting that does not require an explicit deactivation instruction. As shown in the figure, "Option 2: N OD-SSB bursts, where N=4" means that the number of OD-SSB transmissions is pre-configured. UE 120 enables reception at time point A, counts OD-SSB bursts, and stops receiving / reporting after N OD-SSB bursts.
[0197] In one embodiment, the UE 120 may set a counter for a first SSB used to count the number of SSB bursts.
[0198] If the counter of the first SSB expires, stop receiving the first transmission of the first SSB; and
[0199] If the counter of the first SSB has not expired, the first transmission of the first SSB is received.
[0200] In one embodiment, for the configuration / indication of the number of N OD-SSB bursts to be transmitted after OD-SSB is enabled, OD-SSB can be associated with a counter. If the counter has not expired (Counter>0), OD-SSB is transmitted. If the counter expires (Counter<=0), OD-SSB transmission is stopped.
[0201] For example, Figure 8 This is a schematic diagram illustrating the implicit deactivation mechanism of the OD-SSB associated with the counter according to an embodiment of the present invention. (Refer to...) Figure 8 A counter is defined as a variable used to count the number of SSB bursts. When OD-SSB is enabled (or at time point A), the counter is set to N (e.g., N=4). Time point A is the start time of the first time slot containing the SSB index of the first actual transmission within the first "possible" OD-SSB burst, which is located at least T time slots after the time slot in which UE 120 receives signaling from network device 110 (e.g., gNB) to indicate OD-SSB transmission, where T is not less than T_min (e.g., T_min = ...). And m and (These are parameters related to parametrics and processing capacity). The counter decrements with each cycle P (or each SSB burst). At Counter = 4, 3, 2, 1: these correspond to actual OD-SSB transmissions (Counter > 0). At Counter = 0: the counter expires. This corresponds to a virtual OD-SSB (Counter <= 0), where no actual OD-SSB transmission occurs.
[0202] Figure 9 This is a flowchart illustrating a method for a method of implicitly disabling the OD-SSB associated with a counter decrement mechanism according to an embodiment of the present invention. (Refer to...) Figure 9In step S910, UE 120 receives an OD-SSB enable command. UE 120 sets Counter=N and Timer=P at time point A. In step S920, UE 120 receives an OD-SSB, which is associated with a counter. In step S930, UE 120 checks if the Timer has expired. Here, "expired" is defined as the counter reaching a threshold, for example, zero (or less than or equal to zero) in a decrement mechanism. If the Timer has not expired, UE 120 continues to receive OD-SSBs. However, in step S940, if the Timer expires, Counter is decremented (e.g., Counter = Counter - 1). In step S950, UE 120 checks if Counter is less than or equal to 0. In step S960, if Counter is greater than 0, UE 120 sets the Timer to period P and continues to receive OD-SSBs. In step S970, if Counter is less than or equal to 0, UE 120 stops receiving OD-SSB.
[0203] In one embodiment, the UE 120 may set a counter for the first SSB to count the number of SSB bursts.
[0204] If the counter of the first SSB expires, stop receiving the first transmission of the first SSB; and
[0205] If the counter of the first SSB has not expired, the first transmission of the first SSB is received.
[0206] In one embodiment, for the configuration / indication of N OD-SSB bursts to be transmitted after OD-SSB is enabled, the CSI report may meet the following criteria:
[0207] CSI reports can be transmitted when the corresponding OD-SSB's counter has not expired (e.g., Counter > 0);
[0208] CSI reporting can be stopped or deactivated when the corresponding OD-SSB counter expires (e.g., Counter <= 0).
[0209] For example, Figure 10 This is a schematic diagram illustrating the CSI reporting mechanism for OD-SSB using a counter, according to an embodiment of the present invention. (Refer to...) Figure 10, Enabled: At time point A, the counter is initialized (set Counter = N = 4). Enabled phase: In the time intervals when Counter = N, N - 1, N - 2, and 1 (e.g., N = 4), the OD-SSB bursts are transmitted in the actual transmission manner. At time t1 to time t4, since the counters of the corresponding OD-SSBs have not expired (Counter > 0), UE 120 performs CSI reporting respectively. Expired: After the 4th SSB burst, Counter becomes 0. Subsequent SSB bursts are "virtual OD-SSBs" (not transmitted). After UE 120 learns the counter status, since the counter of the corresponding OD-SSB has expired (Counter <= 0), CSI reporting stops at time t5.
[0210] Alternatively, the counter can be implemented as an incrementing variable. Figure 11 is a flowchart illustrating the implicit deactivation mechanism of OD-SSB associated with the counter increment mechanism according to an embodiment of the present invention. Refer to Figure 11 , in step S1110, UE 120 starts the OD-SSB procedure and sets Counter (e.g., initially 0 or 1) and Timer (e.g., initially with period P) at time point A. In step S1120, UE 120 receives the OD-SSB. UE 120 checks if the Timer has expired. If the Timer has not expired (e.g., Counter < N), UE 120 continues to receive the OD-SSB (step S1130). In step S1140, Counter is then incremented (e.g., Counter = Counter + 1) and the Timer is reset. In step S1150, UE 120 checks if Counter is greater than or equal to N. If not, in step S1160, UE 120 sets the Timer to period P. If Counter reaches its limit value (greater than or equal to N), UE 120 stops receiving the SSB (step S1170) as the end of the OD-SSB procedure.
[0211] In one embodiment, the CSI reporting can conform to the following situations:
[0212] When the counter of the corresponding OD-SSB has not expired (e.g., Counter < N), the CSI reporting can be transmitted;
[0213] When the counter of the corresponding OD-SSB has expired (e.g., Counter >= N), the CSI reporting can be stopped / deactivated / dropped (or not updated).
[0214] For example, Figure 12This is a schematic diagram illustrating the CSI reporting mechanism for OD-SSB using a counter, according to an embodiment of the present invention. (Refer to...) Figure 12 At time t0, CSI reporting is enabled. At time t1, CSI reporting is transmitted (Counter has not expired or Counter > 0). Subsequently, CSI reporting is stopped / disabled (no corresponding measurement resource or Counter <= 0). δ is the minimum processing time for CSI measurements.
[0215] In one embodiment, UE 120 may receive a first channel state information (CSI) report configuration, receive a third signaling, and transmit a first CSI report according to the third signaling, the third signaling being used to enable a first CSI report corresponding to a first SSB and configured by the first CSI report configuration.
[0216] Figure 13 This is a flowchart illustrating a method for implementing a CSI reporting mechanism for OD-SSB using a counter, according to an embodiment of the present invention. (Refer to...) Figure 13 The transmission of CSI reports is conditionally performed based on a counter. In step S1310, UE 120 receives an enable instruction for CSI reporting of OD-SSB and sets the counter. In step S1320, for a CSI reporting opportunity, UE 120 performs CSI reporting of OD-SSB, where OD-SSB is associated with the counter. In step S1330, UE 120 checks whether the Counter is greater than 0. If yes, in step S1340, UE 120 may perform CSI reporting, for example, reporting CSI of OD-SSB. If no, in step S1350, UE 120 may not perform CSI reporting, for example, stopping reporting CSI of OD-SSB.
[0217] In one embodiment, for the configuration / indication of the number of N OD-SSB bursts to be transmitted after OD-SSB is enabled, OD-SSB may be associated with a state. When in a first state (e.g., State 0), no OD-SSB transmission occurs. When in a second state (e.g., State 1), OD-SSB transmission occurs.
[0218] For example, Figure 14 This is a schematic diagram illustrating the implicit deactivation mechanism of the OD-SSB associated with a state, according to an embodiment of the present invention. (Refer to...) Figure 14OD-SSB is associated with a state, such as a first state (e.g., State 0) and a second state (e.g., State 1). The first state indicates no OD-SSB transmission (or a virtual transmission), while the second state indicates actual OD-SSB transmission. UE 120 sets the state to the second state (State 1) at time A, which corresponds to the start time of the first actual transmitted SSB burst. The duration of the enabled state (State 1) is calculated as N. P, where N is the number of SSB bursts and P is the period of the SSB bursts. Therefore, at time point A+N P, UE 120 will transition back to the first state (State 0). Time point A and time point A+N The time interval between P is designated as State 1, during which UE 120 expects valid SSB transmissions and can perform the corresponding CSI report. Outside this time interval, the state is State 0, and UE 120 may not perform valid SSB transmissions.
[0219] Figure 15 This is a flowchart illustrating a method for a state-associated implicit deactivation mechanism of the OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 15 First, in step S1510, the state is set to "State 0", and OD-SSB transmission is not performed. In step S1520, UE 120 receives an OD-SSB enable command. Based on the enable command and configured parameters (e.g., N OD-SSB bursts and their period P), UE 120 sets the state to "State 1" at time point A (step S1530). UE 120 is also scheduled at time point A+N. P transitions to "State 0". In step S1540, UE 120 monitors OD-SSB based on the current state. If the current time is within the time interval [A, A+N]... If the state is within P), then the state is State 1, and UE 120 receives OD-SSB. UE 120 checks whether the Nth OD-SSB has been received (e.g., at time A+N). (P) (Step S1550). After UE 120 receives the Nth OD-SSB (e.g., at its arrival time A+N). When P), the state changes to State 0, OD-SSB is no longer transmitted, and UE120 stops receiving OD-SSB (step S1560).
[0220] In one embodiment, for the configuration / indication of N OD-SSB bursts to be transmitted after OD-SSB is enabled, the CSI report may meet the following criteria:
[0221] When the corresponding OD-SSB is in the first state (e.g., State 0), the CSI report may not be transmitted;
[0222] CSI reports can be transmitted when the corresponding OD-SSB is in the second state (e.g., State 1).
[0223] For example, Figure 16 This is a schematic diagram illustrating a CSI reporting mechanism utilizing the state of the OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 16 The timeline shows multiple CSI reporting opportunities (times t0 to t5). The minimum processing time δ for CSI measurements is also indicated. At time t0, CSI reporting is enabled. During the period from time t1 to time t4, the corresponding SSB burst is active (e.g., State 1 and corresponding to an actual transmitted SSB), so CSI reporting is transmitted. However, at time t5, the corresponding SSB burst transitions to another state (e.g., State 0 and corresponding to a virtual transmitted SSB), so CSI reporting is stopped or disabled.
[0224] In one embodiment, UE 120 may set the state of a first SSB used for counting the number of SSB bursts.
[0225] If the state of the first SSB is in the first state, stop transmitting the first CSI report corresponding to the first SSB; and
[0226] If the state of the first SSB is the second state, transmit the first CSI report corresponding to the first SSB.
[0227] Figure 17 This is a flowchart illustrating a method for utilizing the CSI reporting mechanism of the OD-SSB of the present invention, according to an embodiment of the present invention. (Refer to...) Figure 17 In step S1710, UE 120 receives an enable instruction for CSI reporting of the OD-SSB. In step S1720, for the CSI reporting timing, UE 120 performs CSI reporting of the OD-SSB associated with the state. In step S1730, UE 120 checks whether the state is a second state (e.g., State 1). If yes, in step S1740, UE 120 reports the CSI of the OD-SSB. That is, UE 120 can perform CSI reporting. If no, in step S1750, UE 120 stops reporting CSI (i.e., the CSI reporting procedure is disabled). That is, UE 120 may not perform CSI reporting.
[0228] In one embodiment, CSI reports may meet the following criteria:
[0229] When the corresponding OD-SSB is in the first state (e.g., State 0), the CSI report may not be transmitted or updated;
[0230] CSI reports can be transmitted when the corresponding OD-SSB is in the second state (e.g., State 1).
[0231] For example, Figure 18 This is a schematic diagram illustrating an embodiment of the present invention that utilizes a non-periodic CSI reward mechanism based on a state. (Refer to...) Figure 18 If the OD-SSB is in State 1 (Second State), aperiodic CSI reports can be transmitted. Conversely, if the state is State 0 (First State), aperiodic CSI reports may not be transmitted or updated. As shown in the diagram, at time t0, reports are enabled (e.g., by granting DCI via the uplink). At time t1, because the corresponding SSB burst falls within the State 1 time interval, aperiodic CSI reports are transmitted. At time A+N... After P, the state becomes State 0, and no non-periodic rewards are sent.
[0232] Figure 19 This is a schematic diagram illustrating an explicit deactivation mechanism for an OD-SSB with a deactivation command (e.g., via MAC-CE) according to an embodiment of the present invention. (Refer to...) Figure 19 The MAC-CE provides an explicit OD-SSB deactivation indication for OD-SSB transmission. OD-SSB is enabled at time A. Subsequently, OD-SSB is deactivated at time B (e.g., via MAC-CE).
[0233] In one embodiment, an explicit deactivation indication of the OD-SSB is used via MAC-CE. This OD-SSB may be associated with a state. When in a first state (e.g., State 0), no OD-SSB transmission occurs. When in a second state (e.g., State 1), OD-SSB transmission occurs.
[0234] For example, Figure 20 This is a schematic diagram illustrating an explicit deactivation mechanism for the OD-SSB associated with a state, according to an embodiment of the present invention. (Refer to...) Figure 20 At time A, the first actual SSB burst begins. At time B, UE 120 receives an OD-SSB deactivation command (e.g., via MAC CE). At time C, UE 120 sends an ACK corresponding to the deactivation command. offset It is a fixed, pre-configured, or configurable value, for example, O. offset Greater than or equal to 0. Time interval [A, C+O] offsetThis is defined as State 1 and corresponds to OD-SSB transmission. At time point C+O offset After that, the state transitions to State 0, corresponding to no OD-SSB transmission.
[0235] Figure 21 This is a flowchart illustrating a method for a state-associated explicit deactivation mechanism for OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 21 In step S2110, State is set to 0. In step S2120, UE 120 receives an OD-SSB enable command. In step S2130, UE 120 sets State to 1 at time point A. In step S2140, UE 120 receives OD-SSB. In step S2150, UE 120 checks whether it has received an OD-SSB disable command (e.g., at time point B). If not, it continues to receive commands. If yes, in step S2160, UE 120 at time point C+0... offset Set State = 0, and then stop receiving OD-SSB.
[0236] Figure 22 This is a schematic diagram illustrating a CSI reporting mechanism utilizing the state of the OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 22 At time t0, CSI reporting is enabled. From time t1 to time t4, the corresponding SSB burst is active (State 1 and corresponds to an actual transmitted SSB), thus CSI reporting is transmitted. However, at time t5, the corresponding SSB burst transitions to another state (State 0 and corresponds to a virtual transmitted SSB), thus stopping or disabling CSI reporting.
[0237] Figure 23 This is a flowchart illustrating a method for utilizing the CSI reporting mechanism of the OD-SSB of the present invention, according to an embodiment of the present invention. (Refer to...) Figure 23 In step S2310, UE 120 receives an enable instruction for CSI reporting of the OD-SSB. In step S2320, for the CSI reporting timing, UE 120 performs CSI reporting of the OD-SSB associated with the State. In step S2330, UE 120 checks whether the State is greater than 0 (i.e., State 1). If yes, UE 120 reports the CSI of the OD-SSB (step S2340). That is, UE 120 can perform CSI reporting. If no, UE 120 stops reporting CSI (step S2350) (i.e., disables the CSI reporting procedure). That is, UE 120 may not perform CSI reporting.
[0238] In one embodiment, CSI reports may meet the following criteria:
[0239] When the OD-SSB is in State 0, the CSI report may not be transmitted or updated.
[0240] When the OD-SSB is in State 1, CSI reports can be transmitted.
[0241] For example, Figure 24 This is a schematic diagram illustrating a CSI reporting mechanism utilizing the state of the OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 24 Initially, from time t1 to time t4, CSI reports are transmitted because they correspond to an "actually transmitted OD-SSB" (State 1). At time t5, the report timing corresponds to an "invalid OD-SSB" (State 0). In one embodiment, UE 120 may report the CSI of the "most recent valid" SSB resource after receiving a deactivation instruction for the OD-SSB, instead of simply discarding the report.
[0242] In one embodiment, CSI reports may meet the following criteria:
[0243] When the corresponding OD-SSB is in State 0, the CSI report may not be transmitted or updated.
[0244] CSI reports can be transmitted when the corresponding OD-SSB is in State 1 (second state).
[0245] For example, Figure 25 This is a schematic diagram illustrating an aperiodic CSI reward mechanism utilizing the state of the OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 25 At time t0, aperiodic CSI reporting has been enabled (e.g., via uplink-authorized DCI). Since time t1 falls within the time interval [A, C+O] of State 1. offset Within this timeframe, non-periodic returns are transmitted. However, if the non-periodic returns occur at time point C+O... offset If triggered after (State 0), it will not be transmitted.
[0246] Figure 26 This is a flowchart illustrating a method for explicitly deactivating an OD-SSB in its usage state according to an embodiment of the present invention. (Refer to...) Figure 26In step S2610, State is set to 0. In step S2620, UE 120 receives an OD-SSB enable command. In step S2630, UE 120 sets State to 1 at time point A. In step S2640, UE 120 receives an OD-SSB command. In step S2650, UE 120 checks whether it has received an OD-SSB disable command (e.g., at time point B). If not, it continues to receive commands. If yes, in step S2660, UE 120 sets State to 1 at time point C+0. offset (For example, O) offset >= 0) Stop receiving OD-SSB and set State=0.
[0247] In one embodiment, for an explicit deactivation indication of OD-SSB transmitted via MAC-CE, OD-SSB may be associated with a state. When in a first state (e.g., State 0), OD-SSB transmission is not performed. When in a second state (e.g., State 1), OD-SSB transmission is performed.
[0248] For example, Figure 27 This is a schematic diagram illustrating an explicit deactivation mechanism for the OD-SSB associated with a state, according to an embodiment of the present invention. (Refer to...) Figure 27 At time point A, the first actual SSB transmission begins. At time point B, UE 120 receives the OD-SSB deactivation command. At time point C, UE 120 sends back an ACK corresponding to the deactivation command, where O offset The value equals 0. The valid time interval (State 1) is defined as [A, C).
[0249] Figure 28 This is a flowchart illustrating a method for utilizing the CSI reporting mechanism of the OD-SSB of the present invention, according to an embodiment of the present invention. (Refer to...) Figure 28 In step S2810, UE 120 receives an enable instruction for CSI reporting of the OD-SSB. In step S2820, for the CSI reporting timing, UE 120 executes the corresponding OD-SSB CSI reporting associated with the state. In step S2830, UE 120 checks whether the state is the second state (or State 1). If yes, in step S2840, UE 120 reports the CSI corresponding to the OD-SSB. That is, UE 120 can execute CSI reporting. If no, in step S2850, UE 120 stops OD-SSB CSI reporting (that is, the CSI reporting procedure is disabled). That is, UE 120 may not execute CSI reporting.
[0250] In one embodiment, the timing of a CSI report may be associated with a state for an explicit deactivation indication of OD-SSB via MAC-CE for OD-SSB transmission indication. When in a first state (e.g., State 0), there are no (updated) resources available for a CSI report. When in a second state (e.g., State 1), there are (updated) resources available for a CSI report.
[0251] For example, Figure 29 This is a schematic diagram illustrating an explicit deactivation mechanism for the OD-SSB associated with a state, according to an embodiment of the present invention. (Refer to...) Figure 29 State 1 (effective for reporting) begins at time A+S+δ. δ is the minimum processing time for CSI measurements. While in State 1, there are (updated) resources available for CSI reporting. At time C+O... offset Start with State 0 (invalid). offset It is a fixed, pre-configured, or configurable value, for example, O. offset Greater than or equal to 0. When in State 0, there are no (updated) resources available for CSI reports.
[0252] Figure 30 This is a schematic diagram illustrating an explicit deactivation mechanism for the OD-SSB associated with a state, according to an embodiment of the present invention. (Refer to...) Figure 30 At time point A, the first actual SSB transmission begins. At time point B, UE 120 receives the OD-SSB deactivation command. At time point C, UE 120 sends back an ACK corresponding to the deactivation command. During the State 1 time interval [A+S+δ, C+O...] offset Within the State 1 timeframe, there are (updated) resources available for CSI reporting. However, outside the State 1 timeframe, there are no (updated) resources available for CSI reporting.
[0253] Figure 31 This is a flowchart illustrating a method for a state-associated explicit deactivation mechanism for OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 31 In step S3110, UE 120 sets State=0. In step S3120, UE 120 receives an OD-SSB enable command. In step S3130, UE 120 receives OD-SSB at time point A. In step S3140, UE 120 sets State=1 at time point A+S+δ. In step S3150, UE 120 determines whether it has received a disable command (e.g., at time point B). If not, UE 120 continues to receive OD-SSB. If yes, in step S3160, UE 120 at time point C+O... offsetStop receiving / reporting and set State=0.
[0254] In one embodiment, the timing of a CSI report may be associated with a state for an explicit deactivation indication of OD-SSB via MAC-CE for OD-SSB transmission indication. When in a first state (e.g., State 0), there are no (updated) resources available for a CSI report. When in a second state (e.g., State 1), there are (updated) resources available for a CSI report.
[0255] For example, Figure 32 This is a schematic diagram illustrating a CSI reporting mechanism utilizing the state of the OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 32 The CSI reporting is enabled at time t0. In the time interval from time t1 to time t4, the CSI reporting occurs because it falls within the State 1 time interval (A+S+δ to C+O) corresponding to the actual transmission of the OD-SSB. offset Within t5, CSI reports are transmitted. At time t5, the effective window (State 0 and corresponding to the virtual OD-SSB) has expired, and there are no corresponding updated measurement resources, so no CSI reports are sent.
[0256] Figure 33 This is a flowchart illustrating a method for utilizing the CSI reporting mechanism of the OD-SSB of the present invention, according to an embodiment of the present invention. (Refer to...) Figure 33 In step S3310, UE 120 receives an enable command for CSI reporting of OD-SSB. In step S3320, UE 120 determines the State for the CSI reporting timing. In step S3330, UE 120 checks if the State is State 1. If yes, in step S3340, UE 120 reports CSI to OD-SSB. That is, UE 120 can perform CSI reporting. If no, in step S3350, UE 120 stops CSI reporting of OD-SSB (that is, the CSI reporting procedure is disabled). That is, UE 120 may not perform CSI reporting.
[0257] In one embodiment, the timing of a CSI report may be associated with a state for an explicit deactivation indication of OD-SSB via MAC-CE for OD-SSB transmission indication. When in a first state (e.g., State 0), there are no (updated) resources available for a CSI report. When in a second state (e.g., State 1), there are (updated) resources available for a CSI report.
[0258] For example, Figure 34This is a schematic diagram illustrating an explicit deactivation mechanism for the OD-SSB associated with a state, according to an embodiment of the present invention. (Refer to...) Figure 34 The time interval for State 1 is defined as [A+S+δ to C). Any reward opportunity falling after point C corresponds to State 0 (no resources), therefore, CSI rewards are stopped.
[0259] Figure 35 This is a flowchart illustrating a method for a state-associated explicit deactivation mechanism for OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 35 In step S3510, State is set to 0. In step S3520, UE 120 receives an OD-SSB enable command. In step S3530, UE 120 receives OD-SSB at time point A. In step S3540, UE 120 sets State to 1 at time point A+S+δ. In step S3550, UE 120 determines whether a disable command has been received (e.g., at time point B). If not, UE 120 continues to receive OD-SSB. If yes, in step S3560, UE 120 stops receiving / reporting at time point C and sets State to 0.
[0260] In one embodiment, the timing of a CSI report may be associated with a state for an explicit deactivation indication of OD-SSB via MAC-CE for OD-SSB transmission indication. When in a first state (e.g., State 0), there are no (updated) resources available for a CSI report. When in a second state (e.g., State 1), there are (updated) resources available for a CSI report.
[0261] For example, Figure 36 This is a schematic diagram illustrating a CSI reporting mechanism utilizing the state of the OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 36 The time interval for State 1 is [A+δ, C). Here, the start time is simplified to A+δ (assuming S is negligible or included). CSI reports within the time interval from time t1 to time t4 are valid for the actual transmitted OD-SSB. Since the CSI report at time t5 corresponds to a virtual OD-SSB after time point C, and it has no resources for CSI reports, this CSI report is invalid.
[0262] Figure 37 This is a flowchart illustrating a method for utilizing the CSI reporting mechanism of the OD-SSB of the present invention, according to an embodiment of the present invention. (Refer to...) Figure 37In step S3710, UE 120 receives an enable command for CSI reporting of the OD-SSB. In step S3720, UE 120 determines the State used for CSI reporting timing. In step S3730, UE 120 checks whether the state is the second state (or State 1). If yes, in step S3740, UE 120 reports the corresponding OD-SSB CSI. That is, UE 120 can perform the corresponding OD-SSB CSI reporting. If no, in step S3750, UE 120 stops the corresponding OD-SSB CSI reporting (that is, the CSI reporting procedure is disabled). That is, if the state is the first state (or State 0), UE 120 may not perform CSI reporting.
[0263] In one embodiment, CSI reports may meet the following criteria:
[0264] When the corresponding OD-SSB is in the first state (e.g., State 0), the CSI report may not be transmitted or updated;
[0265] CSI reports can be transmitted when the corresponding OD-SSB is in the second state (e.g., State 1).
[0266] For example, Figure 38 This is a schematic diagram illustrating a CSI reporting mechanism utilizing the state of the OD-SSB according to an embodiment of the present invention. (Refer to...) Figure 38 The time interval for State 1 is defined as [A+δ, C). Since times t1, t2, t3, and t4 fall within this time interval, the corresponding CSI reports are sent. However, the CSI report at time t5 is invalid because it corresponds to a virtual OD-SSB after time point C, and it has no resources available for CSI reporting.
[0267] In one embodiment, for periodic CSI reporting, the UE may report its CSI based on the following conditions:
[0268] Proposal 1A:
[0269] CSI reports can be transmitted / restored / enabled when the corresponding OD-SSB counter has not expired (Counter>0).
[0270] When the corresponding OD-SSB counter expires (Counter<=0), the CSI report can be silenced / discarded / stopped / disabled.
[0271] Proposal 1A':
[0272] When the corresponding OD-SSB is in State 0, CSI reports can be silenced / discarded / stopped / disabled.
[0273] When the corresponding OD-SSB is in State 1, CSI reports can be transmitted / restored / enabled.
[0274] Proposal 1B:
[0275] When the corresponding OD-SSB is in State 0, CSI reports can be silenced / discarded / stopped / disabled.
[0276] When the corresponding OD-SSB is in State 1, CSI reports can be transmitted / restored / enabled.
[0277] Proposal 1B':
[0278] When the CSI reporting time is in State 0, the CSI report can be silenced / discarded / stopped / deactivated.
[0279] When the CSI reporting timing is in State 1, CSI reporting can be transmitted / restored / enabled.
[0280] In one embodiment, UE 120 may receive a fourth signaling for providing a second SSB configuration, receive a second transmission of the second SSB according to the fourth signaling, receive a first CSI report configuration, receive a fifth signaling for enabling a first CSI report corresponding to the first report SSB configured by the first CSI report configuration, and transmit the first CSI report according to the fifth signaling. The fifth signaling may be the same as or different from the first signaling.
[0281] In one embodiment, the first reporting SSB is determined to be one of the first SSB and the second SSB based on the priority of the first SSB and the second SSB.
[0282] In one embodiment, the first reward SSB is predefined as one of the first SSB and the second SSB.
[0283] In one embodiment, the first report SSB is configured by receiving a sixth signaling message for configuring the first report SSB.
[0284] In one embodiment, the first reward SSB is the nearest valid SSB between the first SSB and the second SSB.
[0285] In one embodiment, the fourth signaling is indicated or provided by DCI, RRC configuration or MAC-CE; and / or the fifth signaling is indicated or provided by DCI, RRC configuration or MAC-CE.
[0286] Figure 39 This is a schematic diagram illustrating the periodic relationship between OD-SSB and Always-on SSB according to an embodiment of the present invention. (Refer to...) Figure 39 Both SSB types (OD-SSB and Always-on SSB) coexist. Always-ON SSB This is the cycle of Always-on SSB (usually quite long). P OD-SSB This is the OD-SSB cycle (usually shorter). T Always-ON SSB This is the previous Always-on SSB location. OD-SSB It is the starting position of OD-SSB.
[0287] In one embodiment, T Always-ON SSB and T OD-SSB There is no time difference between them. Configure a single CSI report configuration, where CSI resources can come from both Always-on SSB and OD-SSB.
[0288] In one embodiment, T Always-ON SSB and T OD-SSB The time difference between them is limited to P. OD-SSB Multiples of (e.g., K) P OD-SSB (where K is an integer equal to 1 and / or greater than 1). Configure independent CSI reporting configurations, where for each configuration, CSI resources can come from Always-on SSB or OD-SSB.
[0289] In one embodiment, for a single CSI report configuration where CSI resources originate from both Always-on SSB and OD-SSB, different types of SSBs may have different priorities. UE 120 may transmit CSI reports based on one of a first set of SSBs (e.g., Always-on SSB) and a second set of SSBs (e.g., OD-SSB).
[0290] In one embodiment, for a single CSI report configuration where CSI resources originate from both Always-on SSB and OD-SSB, different types of SSBs may have the same priority. UE 120 may transmit CSI reports based on both a first set of SSBs (e.g., Always-on SSB) and a second set of SSBs (e.g., OD-SSB).
[0291] In one embodiment, for a single CSI report configuration, the CSI resources come from both Always-on SSB and OD-SSB, and the UE 120 receives the CSI report configuration. The CSI report configuration may include at least one first SSB set (e.g., Always-on SSB, with a first index) and a second SSB set (e.g., OD-SSB, with a second index).
[0292] Before point A (OD-SSB is not enabled), UE 120 transmits CSI reports based on the first SSB set of the SSB group (e.g., Always-on SSB).
[0293] During the period from time point A to time point B (OD-SSB is enabled).
[0294] Proposal 2A-1: UE 120 transmits CSI reports based on the second SSB set (e.g., OD-SSB) of the SSB group (e.g., the second SSB set has higher priority, e.g., higher or lower resource / set index).
[0295] Proposal 2A-2: UE 120 transmits CSI reports based on the most recent available resources of the first SSB set (e.g., Always-on SSB) or the second SSB set (e.g., OD-SSB) of the SSB group (e.g., the first and second SSB sets have the same priority).
[0296] After point B (when OD-SSB is disabled), UE 120 transmits CSI reports based on the first SSB set of the SSB group (e.g., Always-on SSB).
[0297] In one embodiment, for a single CSI report configuration, CSI resources simultaneously originate from Always-on SSBs (set 0) and OD-SSBs (set 1) with different priorities, and the set index is associated with the priority of the CSI report; for example, a higher set index corresponds to a higher CSI report priority. [Implicit indication]. In another embodiment, UE 120 may receive the priority of the CSI resource set from the network. [Explicit indication].
[0298] For example, Figure 40 This is a schematic diagram illustrating CSI reports with different priorities according to an embodiment of the present invention. (Refer to...) Figure 40Prior to time point A, UE 120 reported based on set 0 (Always-on SSB, lower priority). At time point A, when set 1 (OD-SSB, higher priority) was enabled, UE 120 switched to reporting based on set 1. Counters (e.g., Counter=3, 2, 1) tracked OD-SSB bursts. When OD-SSB bursts were exhausted (Counter=0), UE 120 switched back to reporting based on set 0 (Always-on SSB).
[0299] In one embodiment, in case A, when UE 120 receives an OD-SSB enable instruction, for a CSI reporting opportunity after time point A+Offset, if the Counter>0 and / or State>0 of the SSB corresponding to the CSI reporting opportunity, UE 120 may perform CSI measurement / reporting based on a second SSB set (e.g., OD-SSB). Offset may be a higher-layer configuration or a fixed value >=0. In one embodiment, in case B, UE 120 may instead perform CSI measurement / reporting based on a first SSB set (e.g., Always-onSSB).
[0300] In one embodiment, for a single CSI reporting configuration, the CSI resources come from Always-onSSB (set 0) and OD-SSB (set 1) with the same priority, and the UE 120 can report the CSI of the nearest valid SSB resource.
[0301] For example, Figure 41 This is a schematic diagram illustrating CSI reports with the same priority according to an embodiment of the present invention. (Refer to...) Figure 41 Sets 0 and 1 have the same priority. For any given return timing (e.g., time t4), UE 120 selects the "nearest valid SSB" resource. If the OD-SSB burst is more recent in time and valid, the OD-SSB burst is used. If the Always-on SSB is more recent in time, the Always-on SSB is used.
[0302] In one embodiment, a single CSI report configuration can be configured with report types: {periodic, semi-persistent scheduling, semi-persistent-like scheduling, aperiodic, event-triggered, UE-initiated}. CSI reports can be triggered by DCI (aperiodic, single report).
[0303] In one embodiment, UE 120 may receive a seventh signaling for providing a second SSB configuration, receive a second transmission of the second SSB according to the seventh signaling, receive a first CSI report configuration, receive a second CSI report configuration, transmit a first CSI report corresponding to the first SSB and configured by the first CSI report configuration, and transmit a second CSI report corresponding to the second SSB and configured by the second CSI report configuration.
[0304] In one embodiment, UE 120 may transmit a first CSI report corresponding to the first SSB and configured by the first CSI report configuration if the first CSI report is enabled, and stop transmitting the first CSI report if the first CSI report is not enabled.
[0305] In one embodiment, UE 120 may receive a second CSI report configuration, and, if the first CSI report is not transmitted, transmit a second CSI report corresponding to the second SSB and configured by the second CSI report configuration.
[0306] In one embodiment (Proposal 2B), a separate CSI reporting configuration is provided, wherein the CSI resources come from Always-onSSB or OD-SSB.
[0307] Proposal 2B-1: If OD-SSB transmission is performed, only one CSI report can be transmitted (e.g., because of its higher priority, the UE transmits the CSI report according to the second configuration of the SSB (e.g., OD-SSB)).
[0308] Proposal 2B-2: More than one CSI report can be transmitted (e.g., the UE transmits CSI reports simultaneously according to the first configuration of the SSB (e.g., Always-on SSB) and the second configuration of the SSB (e.g., OD-SSB).
[0309] In one embodiment (Proposal 2B), a separate CSI reporting configuration is provided, wherein the CSI resources come from Always-onSSB or OD-SSB.
[0310] Proposal 2B-1: Only one CSI report configuration (e.g., different priorities) can be transmitted.
[0311] The UE receives the SSB group / pairing configuration, where
[0312] SSB groups / pairs must contain at least a first configuration of SSB (e.g., Always-on SSB) and a second configuration of SSB (e.g., OD-SSB).
[0313] If CSI reporting for OD-SSB is not transmitted / enabled, CSI reporting is based on the SSB's default configuration (e.g., the SSB's first configuration (e.g., Always-on SSB)).
[0314] If CSI reports for OD-SSB are transmitted / enabled, the CSI reports are based on the SSB configuration with higher priority (e.g., the second configuration of the SSB (e.g., OD-SSB)).
[0315] Proposal 2B-2: Allow more than one CSI report configuration (e.g., the same priority) to be transmitted.
[0316] For example, Figure 42 This is a schematic diagram illustrating, according to an embodiment of the present invention, the use of a counter to perform CSI reporting for only one CSI reporting configuration at a time. (Refer to...) Figure 42 Regarding Proposal 2B-1, UE 120 is configured with multiple CSI report configurations, such as a first configuration (Config. 0) associated with a first SSB set (e.g., Always-on SSB) and a second configuration (Config. 1) associated with a second SSB set (e.g., OD-SSB). Config. 1 (OD-SSB) has a higher priority than Config. 0 (Always-on SSB). Switching between configurations is controlled by the Counter of OD-SSB. During time intervals where Counter > 0 (e.g., Counter = 3, 2, 1): OD-SSB is active. UE 120 transmits CSI reports according to Config. 1. Simultaneously, UE 120 may stop, discard, or disable CSI reports for Config. 0 to conserve resources or avoid collisions. During time intervals where Counter is less than or equal to 0 (e.g., Counter = 0): OD-SSB transmission ends. UE 120 stops transmitting CSI reports according to Config. 1. Meanwhile, UE 120 recovers or transmits CSI reports according to Config. 0.
[0317] Figure 43 This is a schematic diagram illustrating, according to an embodiment of the present invention, CSI reporting using only one CSI report configuration at a time, taking advantage of the state. (Refer to...) Figure 43Regarding Proposal 2B-1, the handover between configurations is controlled by the state of OD-SSB. In State 1 (OD-SSB enabled): UE 120 transmits CSI reports for high-priority Config. 1 (OD-SSB) and stops / discards CSI reports for Config. 0 (Always-on SSB). In State 0 (OD-SSB disabled): UE 120 stops CSI reports for Config. 1 and transmits / resumes CSI reports for Config. 0. During the time interval from time t2 to time t4 (State 1), only CSI reports for OD-SSB are transmitted. At time t5 (State 0), CSI reports for Always-on SSB are resumed, but no CSI reports for OD-SSB are transmitted.
[0318] In one embodiment, in case A, when UE 120 receives the OD-SSB enable command, the timing of the CSI report after time point A+Offest is...
[0319] If the Counter of the SSB corresponding to the CSI reporting timing is > 0 and / or the State is > 0, the UE can perform CSI measurement / reporting according to Config. 1 of Group A (OD-SSB).
[0320] If the Counter of the SSB corresponding to the CSI reporting timing is <= 0 and / or the State is <= 0, the UE can silence / discard / stop / disable CSI measurement / reporting according to Config. 0 of Group A (Always-on SSB). In one embodiment, in case B, the UE 120 can instead perform CSI measurement / reporting according to Config. 0 of Group A (Always-on SSB).
[0321] For example, Figure 44 This is a schematic diagram illustrating, according to an embodiment of the present invention, the use of a counter to perform CSI reporting configurations with more than one CSI report at the same time. (Refer to...) Figure 44 Regarding Proposal 2B-2, UE 120 checks a counter for a specific CSI reporting timing. If the timing corresponds to Config. 1 and Counter is greater than 0, then the OD-SSB CSI reporting is transmitted. If the timing corresponds to Config. 1 and Counter is less than or equal to 0, then the OD-SSB CSI reporting is not transmitted. However, UE 120 performs CSI measurement / reporting according to Config. 0 (Always-on SSB) of Group A.
[0322] Figure 45This is a schematic diagram illustrating, according to an embodiment of the present invention, how to perform CSI reporting by utilizing a state to use more than one CSI reporting configuration at the same time. (Refer to...) Figure 45 Regarding Proposal 2B-2, UE 120 checks the state of a specific CSI reporting timing. If the timing corresponds to Config. 1 and State is State 1, then the OD-SSB CSI reporting is transmitted. If the timing corresponds to Config. 1 and State is State 0, then the OD-SSB CSI reporting is not transmitted. However, UE 120 performs CSI measurement / reporting according to Config. 0 (Always-on SSB) of Group A.

Figure 46 In step S4610, network device 110 transmits first signaling. In step S4620, network device 110 transmits the first transmission of the first SSB according to the first signaling. For a detailed description, please refer to the above embodiment.
