Description

TECHNICAL FIELD

[0001] The present disclosure relates to a communication mechanism, and in particular, to a method of communication operation and a user equipment (UE). BACKGROUND

[0002] In 5G New Radio (NR) systems, Synchronization Signal / PBCH (Physical Broadcast Channel) Block (SSB) burst is introduced to support beam sweeping. SSB burst is realized by Time Division Multiplexing (TDM) to change beam direction and transmitted as a burst in the downlink. SSB burst is confined within a 5 millisecond window and transmitted with a periodicity of 5, 10, 20, 40, 80 or 160 milliseconds, with a default of 20 milliseconds. The SSB transmission pattern of each SSB burst is configured using a Radio Resource Control (RRC) parameter named ssb-PositionsInBurst.

[0003] In ssb-PositionsInBurst, the first / leftmost bit corresponds to SS / PBCH block index 0, the second bit corresponds to SS / PBCH block index 1, and so on. A value of 0 in the bitmap indicates that the corresponding SS / PBCH block is not transmitted, while a value of 1 indicates that the corresponding SS / PBCH block is transmitted. The network configures the same pattern in this field as in the corresponding field in ServingCellConfigCommonSIB.

[0004] The SSB transmission pattern is typically configured using a short, medium or long bitmap, supporting up to 4, 8 and 64 beams per SSB burst, respectively.

[0005] Referring to Figure 1 , which shows a schematic diagram of SSB burst. In Figure 1 , ssb-PositionsInBurst can be, for example, [1111 1111] and the SSB transmission pattern (i.e. SSB bitmap) can correspond to a medium bitmap, which indicates up to 8 beams per SSB burst.

[0006] However, to ensure continuous synchronization coverage, the current system configuration keeps SSB transmission always on, even in energy saving configurations, such as Network Energy Saving (NES) defined in 3GPP Release 18. This “always on” approach can lead to unnecessary energy consumption in certain cases.

[0007] Referring to Figure 2 , which shows a schematic diagram of the NES concept.

[0008] As Figure 2As shown, for Rel-18 NES, a UE can be configured with a non-NES cell and at least one NES cell, where the NES cell supports NES operation and the non-NES cell can be a primary cell (PCell) or a primary SCell (PSCell).

[0009] In Release 18, cell DTX (discontinuous transmission) is introduced to improve network energy efficiency, allowing scheduling of inactive state for power saving for certain periods.

[0010] For example, a UE can receive a physical downlink shared channel (PDSCH) during a cell DTX on duration, and the UE can not receive the PDSCH during a cell DTX off duration.

[0011] Referring to Figure 3 , a diagram showing the relationship between DTX duration and SSB transmission.

[0012] In Figure 3 , a UE can receive a PDSCH during a cell DTX on duration, and the UE can not receive the PDSCH during a cell DTX off duration.

[0013] As seen in Figure 3 , SSBs continue to be transmitted even during the cell DTX off duration, resulting in potential inefficiency. For example, energy consumption can be a serious issue due to SSBs always being on. In addition, the network configures the same pattern in this field as the corresponding field in ServingCellConfigCommonSIB.

[0014] In addition, the association between SSBs and channel state information reference signals (CSI-RSs), such as beam pairing and quasi co-location (QCL), also affects CSI measurement and reporting overhead, especially when multiple SSBs and CSI-RSs are involved in the configuration.

[0015] Referring to Figure 4 , a diagram showing quasi co-location relationship between SSB beams and CSI-RS beams.

[0016] In Figure 4 , a network node (e.g., a base station) can transmit 4 SSB beams represented by SSB#0 to SSB#3 and 12 CSI-RS beams represented by CSI-RS 0 to CSI-RS11.

[0017] As seen in Figure 4As shown, there is a quasi co-location relationship between SSB#0 and CSI-RS 0 to CSI-RS2, between SSB#1 and CSI-RS 3 to CSI-RS 5, between SSB#2 and CSI-RS 6 to CSI-RS 8, and between SSB#3 and CSI-RS 9 to CSI-RS11.

[0018] In this case, the quasi co-location relationship between SSB beams and CSI-RS beams can be indicated by a signaling named nzp-CSI-ResourceToAddModList as shown. Figure 4

[0019] Referring to Figure 5 , which shows a SSB diagram for cell planning.

[0020] In Figure 5 , which shows that the number and configuration of CSI-RS beams that are quasi co-located (QCLed) with each SSB beam directly impact the beam planning efficiency and UE measurement workload.

[0021] For example, as Figure 5 shown on the left, when SSB#0 is selected, the UE monitors CSI-RS 0 to CSI-RS 5, providing more CSI-RS candidates but resulting in higher CSI reporting overhead.

[0022] In contrast, as Figure 5 shown on the right, selecting SSB#2 requires the UE to monitor only CSI-RS 0 and CSI-RS1, resulting in fewer CSI-RS candidates and reduced reporting overhead.

[0023] However, as mentioned above, the always-on periodic SSB transmission can consume unnecessary network energy. In addition, the semi-statically configured SSB transmission pattern can not reflect its immediate spatial domain characteristics (beams). SUMMARY

[0024] Therefore, the present application proposes a communication operation method and a UE, which can be used to solve the above technical problems.

[0025] Embodiments of the present application provide a communication operation method performed by a UE. The method comprises: receiving first signaling for indicating first information related to a first SSB set; and receiving second signaling for indicating second information related to a second SSB set.

[0026] ​Embodiments of the present invention provide a UE including a transceiver and a processor. The processor is coupled to the transceiver and configured to perform: receiving first signaling for indicating first information associated with a first SSB set; and receiving second signaling for indicating second information associated with a second SSB set.

[0059] Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Where possible, the same reference numerals are used in the drawings and description to refer to the same or similar parts.

[0060] See Figure 6 It displays a UE function block diagram according to an embodiment of the present invention.

[0061] In this embodiment of the invention, the UE 600 can be implemented as various types of communication devices. These include smartphones, tablets with cellular connectivity, laptops equipped with 5G modems, and fixed wireless access (FWA) devices. Furthermore, the UE can take the form of Internet of Things (IoT) terminals, such as smart meters or industrial sensors, in-vehicle communication units for connected or autonomous vehicles, customer premises equipment (CPE), augmented reality / virtual reality (AR / VR) headsets with mobile broadband capabilities, and drones or unmanned aerial vehicles (UAVs) with integrated 5G modules. These devices typically integrate the necessary protocol stacks, physical layer components, and radio interfaces to communicate with 5G network infrastructure.

[0062] exist Figure 6In this UE 600, a transceiver 602 and a processor 604 are included. The transceiver 602 can be configured to transmit and receive signals with other devices within its coverage area. The transceiver 602 is capable of performing analog-to-digital signal conversion (ADC), digital-to-analog signal conversion (DAC), modulation, demodulation, signal amplification, low-pass filtering, and band-pass filtering. For example, the transceiver 602 is configured to provide received signal information to the processor 604, modulate data received from the processor 604 into a modulated signal, and transmit the modulated signal to other devices.

[0063] In some embodiments, the UE 600 may also include other components, such as an antenna module for implementing the aforementioned functions of the transceiver 602 and the processor 604.

[0064] Processor 604 may be coupled to transceiver 602. Processor 604 may be, for example, a general-purpose processor, a special-purpose processor, a conventional processor, a digital signal processor (DSP), multiple microprocessors, one or more microprocessors associated with a DSP core, a controller, a microcontroller, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) circuit, any other type of integrated circuit (IC), a state machine, etc.

[0065] In this embodiment of the invention, the transmission / reception of UE 600 can be performed by the processor 604 of UE 600 controlling the transceiver 602 of UE 600.

[0066] In this embodiment of the invention, processor 604 may be configured to execute the communication operation method proposed in this invention, which will be discussed in detail below.

[0067] See Figure 7 It displays a flowchart of a communication operation method according to an embodiment of the present invention.

[0068] In step S710, the processor 604 controls the transceiver 602 to receive a first signaling for indicating first information related to the first SSB set.

[0069] In this embodiment, the first signaling may be Radio Resource Control (RRC) signaling, Medium Access Control-Control Element (MAC-CE) signaling, or Downlink Control Information (DCI).

[0070] The first information may include, for example, at least one of the following: a first configuration, a first cycle, a first bitmap, a first center frequency, a first frequency offset, or a first transmission configuration indication (TCI).

[0071] More specifically, the first configuration may include one or more of a first period, a first bitmap, a first center frequency, or a first frequency offset.

[0072] In one embodiment, the first SSB set may include a plurality of first SSBs, and the first bitmap may include a plurality of first bits corresponding to the plurality of first SSBs in the first SSB set. In this case, the first bit value of one of the plurality of first bits indicates that the corresponding first SSB in the first SSB set has been transmitted, and the second bit value of one of the plurality of first bits indicates that the corresponding first SSB in the first SSB set has not been transmitted.

[0073] For example, UE 600 may receive a first signaling that carries a first bitmap indicating the transmission status of each SSB in a first SSB set. The first bitmap may include multiple first bits, each corresponding to one of the first SSBs. A bit value "1" may indicate that the corresponding first SSB has been transmitted, while a bit value "0" may indicate that the corresponding first SSB has not been transmitted.

[0074] See Figure 8A and Figure 8B ,in Figure 8A This diagram illustrates the coverage area of ​​the first SSB (Special Support Bundle) according to an embodiment of the present invention. Figure 8B Display according to Figure 8A First SSB set style diagram.

[0075] In an embodiment, network node 800 (which may be a gNB) may transmit a first SSB set, wherein the first SSB set may form a first SSB burst 810.

[0076] In one embodiment, the first information carried by the first signaling may indicate the first bitmap of the first SSB burst 810.

[0077] In one embodiment, the first SSB set may include a plurality of first type SSBs and / or a plurality of second type SSBs.

[0078] In one embodiment, the second type SSB can be divided into multiple subsets corresponding to multiple first type SSBs, each of the multiple first type SSBs having a first beam coverage range, each of the multiple second type SSBs having a second beam coverage range, and the first beam coverage range of one of the multiple first type SSBs covering the second beam coverage range of each of the multiple second type SSBs in the corresponding subset.

[0079] To better understand, Figure 8A and Figure 8B This can be used as an example, but the invention is not limited thereto.

[0080] exist Figure 8A and Figure 8BIn this context, the first set of SSBs may illustratively include SSB#0 to SSB#7, where SSB#0 and SSB#1 may be first type SSBs, and SSB#2 to SSB#7 may be second type SSBs.

[0081] In an embodiment, SSB#2 to SSB#7 can be divided into two subsets, wherein the first subset of the two subsets may include SSB#2 to SSB#4 and correspond to SSB#0, and the second subset of the two subsets may include SSB#5 to SSB#7 and correspond to SSB#1.

[0082] In addition, SSB#0 and SSB#1 may have first beam coverage ranges CV0 and CV1 respectively, and SSB#2 to SSB#7 may have second beam coverage ranges CV2 to CV7 respectively.

[0083] exist Figure 8A In this configuration, the first beam coverage area CV0 of SSB#0 covers the second beam coverage areas CV2 to CV4 of SSB#2 to SSB#4. In this case, SSB#0 can be understood as having a quasi-co-located relationship with SSB#2 to SSB#4.

[0084] Furthermore, the first beam coverage area CV1 of SSB#1 covers the second beam coverage area CV5 to CV7 of SSB#5 to SSB#7. In this case, SSB#1 can be understood as having a quasi-co-located relationship with SSB#5 to SSB#7.

[0085] In this embodiment of the invention, UE 600 may be a specific type of UE that supports NES functionality, and therefore may be referred to as an NES UE. In contrast, UEs that do not support NES functionality may be referred to as conventional UEs, but the invention is not limited thereto.

[0086] In this embodiment of the invention, the NES UE can be informed of the quasi-co-address relationship between the first type SSB and the second type SSB. On the other hand, a conventional UE may not be aware of the quasi-co-address relationship between the first type SSB and the second type SSB.

[0087] exist Figure 8A and Figure 8B In this process, network node 800 can transmit a corresponding first signaling (e.g., MAC-CE signaling) to UE600. The first signaling can accordingly indicate first information of the first SSB set, such as first configuration, first period (e.g., P0), first bit map, first center frequency, first frequency offset, or first TCI.

[0088] Furthermore, since network node 800 transmits SSB#0 to SSB7, the first bitmap may be, for example, [11111111].

[0089] In this case, UE 600 (e.g., NES UE) can communicate with the NES cell via either the first type SSB or the second type SSB and report the SSB selection result to network node 800.

[0090] In one embodiment, the UE 600 monitors multiple first-type SSBs and / or multiple second-type SSBs for at least one of physical downlink control channel detection, beam failure detection, beam failure recovery, or radio link monitoring.

[0091] In one embodiment, if UE 600 communicates with the NES cell via a first type SSB (e.g., SSB#0 or SSB#1), UE 600 may follow conventional behavior. That is, UE 600 may communicate with the NES cell periodically.

[0092] In another embodiment, if UE 600 communicates with the NES cell via a second type SSB (e.g., one of SSB#2 to SSB#7), UE 600 knows that UE 600 can fall back to a first type SSB (e.g., SSB#0 or SSB#1) if needed.

[0093] See Figure 8C Its display is based on Figure 8A A schematic diagram of CSI-RS that has a quasi-co-address relationship with the first SSB set.

[0094] exist Figure 8C In this context, SSB#2 can have a quasi-co-address relationship with CSI-RS 0 and CSI-RS 1; SSB#3 can have a quasi-co-address relationship with CSI-RS 2 and CSI-RS 3; SSB#4 can have a quasi-co-address relationship with CSI-RS 4 and CSI-RS 5; SSB#5 can have a quasi-co-address relationship with CSI-RS 6 and CSI-RS 7; SSB#6 can have a quasi-co-address relationship with CSI-RS 8 and CSI-RS 9; and SSB#7 can have a quasi-co-address relationship with CSI-RS 10 and CSI-RS 11.

[0095] exist Figures 8A-8C In this scenario, UE 600 can perform CSI measurements and reports on CSI-RS 0 to CSI-RS11, but the present invention is not limited thereto.

[0096] See Figure 8D Its display is based on Figures 8A-8C Traditional UE operation diagram.

[0097] exist Figure 8D In this context, the traditional UE 899 is unaware of the aforementioned quasi-co-address relationship between the first type SSB and the second type SSB.

[0098] In an embodiment, the conventional UE 899 may be configured with an SSB transmission pattern: a medium bitmap {ssb-PositionsInBurst[1100 0000]} with a period of P0. In this case, the conventional UE 899 can communicate with the NES cell through one of the first type of SSBs (e.g., SSB#0 or SSB#1) and report its selection result to the network node 800, but the invention is not limited thereto.

[0099] In one embodiment, if the SSB transmission pattern is unknown to the legacy UE 899, the legacy UE 899 may perform blind SSB detection for initial access. The legacy UE 899 then communicates with the NES cell through one of the detected SSBs and reports its selection result to the network node 800.

[0100] However, a traditional UE 899 may not initially know whether the selected SSB corresponds to a Type 1 SSB or a Type 2 SSB.

[0101] If a legacy UE 899 communicates with an NES cell using a Type 1 SSB, the legacy UE 899 can continue to follow legacy behavior. Conversely, if a legacy UE 899 accesses an NES cell using a Type 2 SSB, the legacy UE 899 can be notified to switch from a Type 2 SSB to a Type 1 SSB. This notification can be provided via RRC signaling, MAC-CE, and / or Downlink Control Information (DCI) indicating the transmission configuration indication status of the Control Resource Set (CORESET), such as CORESET#0, but the invention is not limited thereto.

[0102] Back Figure 7 In step S720, the processor 604 controls the transceiver 602 to receive a second signaling for indicating second information related to the second SSB set.

[0103] In one embodiment, the second signaling may be DCI signaling, MAC-CE, or RRC.

[0104] In one embodiment, the second information may include at least one of the following: a second configuration, a second period, a second bitmap, a second center frequency, a second frequency offset, a second TCI, or quasi-co-address information.

[0105] In one embodiment, the second configuration may include one or more of a second period, a second bitmap, a second center frequency, or a second frequency offset.

[0106] In one embodiment, the second SSB set may include a plurality of second SSBs, and the second bitmap may include a plurality of second bits corresponding to the plurality of second SSBs in the second SSB set. In this case, the first bit value of one of the plurality of second bits indicates that the corresponding second SSB in the second SSB set has been transmitted, and the second bit value of one of the plurality of second bits indicates that the corresponding second SSB in the second SSB set has not been transmitted.

[0107] For example, UE 600 may receive second signaling (e.g., RRC signaling) carrying a second bitmap indicating the transmission status of a second set of SSBs. The second bitmap may include multiple second bits, each corresponding to one of the second SSBs. A bit value "1" may indicate that the corresponding second SSB has been transmitted, while a bit value "0" may indicate that the corresponding second SSB has not been transmitted.

[0108] In embodiments of the present invention, the second SSB set may include multiple first-type SSBs. For example, the second SSB set may include... Figure 8D SSB#0 and SSB#1 in the middle, Figure 8D The examples provided are intended to aid understanding, but the invention is not limited thereto.

[0109] exist Figure 8D In this context, a second set of SSBs (e.g., SSB#0 and SSB#1) can form a second SSB burst 820.

[0110] In one embodiment, the second information carried by the second signaling indicates the second bitmap of the second SSB burst 820.

[0111] In one embodiment, if no second period is provided or indicated, the period of the second SSB set may be set to a preset period or the first period of the first SSB set.

[0112] In one embodiment, if no second bitmap is provided or indicated, the second bitmap of the second SSB set may be set to a preset bitmap or the first bitmap of the first SSB set.

[0113] In one embodiment, if a second center frequency is not provided or indicated, the center frequency of the second SSB set may be set to a preset center frequency or the first center frequency of the first SSB set.

[0114] In one embodiment, if no second frequency offset is provided or indicated, the frequency offset of the second SSB set may be set to a preset frequency offset or a first frequency offset of the first SSB set.

[0115] In one embodiment, UE 600 may further perform a first communication operation according to a first signaling. In various embodiments, the first communication operation may include at least one of physical downlink control channel (PDCCH) monitoring, CSI measurement, CSI reporting, beam failure detection (BFD), beam failure recovery (BFR), radio link monitoring (RLM); or physical downlink shared channel reception.

[0116] In one embodiment, the UE 600 monitors multiple first-type SSBs for at least one of physical downlink control channel detection, beam failure detection, beam failure recovery, or radio link monitoring.

[0117] In one embodiment, UE 600 may further perform a second communication operation according to a second signaling. In various embodiments, the second communication operation may include at least one of physical downlink control channel monitoring, CSI measurement, CSI reporting, beam failure detection, beam failure recovery; or physical downlink shared channel reception.

[0118] In one embodiment, the first communication operation may be performed in a first period, and the second communication operation may be performed in a second period.

[0119] For example, UE 600 may determine a first specific SSB (e.g., any one of SSB#0 to SSB#7) belonging to a plurality of first SSBs, and perform a first communication operation using the first specific SSB in a first period. Furthermore, UE 600 may determine a second specific SSB (e.g., SSB#0 or SSB#1) belonging to a plurality of second SSBs, and perform a second communication operation using the second specific SSB in a second period.

[0120] In one embodiment, at least one SSB in the first SSB set has a quasi-co-location relationship with at least one SSB in the second SSB set.

[0121] In one embodiment, the first period and the second period can be the cell DTX on duration and the cell DTX off duration, respectively.

[0122] See Figure 9 It shows a schematic diagram of the cell DTX mechanism according to an embodiment of the present invention.

[0123] exist Figure 9In this context, UE 600 may receive first signaling (e.g., Media Access Control Layer Control Element Signaling) carrying a first bitmap of a first set of SSBs (e.g., SSB#0 to SSB#7) indicating a first period 910 (e.g., cell DTX on-time duration). For example, the first bitmap may be characterized as “mediumBitmap{ssb-PositionsInBurst-NES[1111 1111]}”.

[0124] In addition, UE 600 may receive a second signaling (e.g., radio resource control) carrying a second bitmap of a second set of SSBs (e.g., SSB#0 and SSB#1) indicating a second period 920 (e.g., cell DTX off duration). For example, the second bitmap may be characterized as “mediumBitmap{ssb-PositionsInBurst-NES[1100 0000]}”.

[0125] In other words, network node 800 can transmit SSB#0 to SSB#7 in the first period 910, which is beneficial to channel capacity. On the other hand, network node 800 can transmit SSB#0 and SSB#1 in the second period 920, which is beneficial to NES.

[0126] From another perspective, cell coverage will not be degraded because the first type of SSB (e.g., SSB#0 and SSB#1) can also support the same cell coverage as the second type of SSB (e.g., SSB#2 to SSB#7), so that the control link can be maintained.

[0127] exist Figure 9 In this context, the first period of the first SSB set (e.g., P0) may be different from the second period of the second SSB set (e.g., P1). Furthermore, the second period of the second SSB set (e.g., P1) may be a multiple of the first period of the first SSB set (e.g., P0) (e.g., P1 = K * P0, where K is a positive integer).

[0128] Furthermore, traditional UEs will not be affected by the specification because Type 1 SSB transmissions remain the same in both Phase 1 (910) and Phase 2 (920).

[0129] In one embodiment, UE 600 (e.g., NES UE) can communicate with the NES cell via a first type SSB (e.g., SSB#0 or SSB#1) or a second type SSB (e.g., any one of SSB#2 to SSB#7) and report the selection result to network node 800 in the first period 910.

[0130] On the other hand, UE 600 (e.g., NES UE) can communicate with the NES cell via a first type SSB (e.g., SSB#0 or SSB#1) and report the selection result to network node 800 in the second period 920.

[0131] In one embodiment, if UE 600 communicates with the NES cell via a second type SSB (e.g., any one of SSB#2 to SSB#7) during the first period 910 (e.g., the cell-DTX on duration), UE 600 knows that UE 600 can fall back to the corresponding first type SSB (e.g., SSB#0 or SSB#1) when (or before) transitioning from the first period 910 to the second period 920.

[0132] For example, if UE 600 communicates with the NES cell via SSB#2 during the first period 910, UE 600 knows that it can fall back to SSB#0, which has a quasi-co-location relationship with SSB#2, when transitioning from the first period 910 to the second period 920 (or before). As another example, if UE 600 communicates with the NES cell via SSB#6 during the first period 910, UE 600 knows that it can fall back to SSB#1, which has a quasi-co-location relationship with SSB#6, when transitioning from the first period 910 to the second period 920 (or before).

[0133] See Figure 10 According to Figure 9 This diagram illustrates different SSB transmission patterns in different cycles.

[0134] exist Figure 10 In the first period 910, network node 800 may transmit a first SSB burst 1010 in a first cycle (e.g., P0), wherein the first SSB burst 1010 may include Figure 9 SSB#0 to SSB#7.

[0135] Furthermore, network node 800 may transmit a second SSB burst 1020 in a second period (e.g., P1) during the second phase 920, wherein the second SSB burst 1020 may include Figure 9 SSB#0 and SSB#1 (i.e., SSB#2 to SSB#7 are not transmitted).

[0136] In an embodiment, a first type of SSB (e.g., SSB#0 and SSB#1) can be used for physical downlink control channel detection (a physical downlink control channel with a set of control resources having a transmission configuration indication state (e.g., SSB#0 or SSB#1 or a CSI-RS having a quasi-co-address relationship with SSB#0 or #1)).

[0137] Furthermore, the first and second types of SSBs can be used for physical downlink shared channel reception, but the present invention is not limited thereto.

[0138] See Figure 11A According to Figure 10 This diagram illustrates the behavior of the UE during the first period.

In this case, UE 600 can monitor first type SSBs (e.g., SSB#0 and SSB#1) for physical downlink control channel detection, beam failure detection, beam failure recovery, and radio link monitoring. Furthermore, UE 600 can monitor the first and second types of SSBs for time / frequency synchronization, CSI measurement, and physical downlink shared channel reception, but the invention is not limited thereto.

[0140] See Figure 11B According to Figure 11A This diagram illustrates the CSI measurements and reporting performed during the first period.

[0141] In an embodiment, during the first period 910, the UE 600 may use CSI-RS 0 to CSI-RS11, which have quasi-co-located relationships with SSB#2 to SSB#7, to perform CSI measurements and reports.

[0142] See Figure 12 According to Figure 10 This diagram illustrates the behavior of the UE during the second period.

[0143] exist Figure 12 In the second period 920, UE 600 can be configured / indicated to have a second period P1 and a second bitmap characterized as “mediumBitmap{ssb-PositionsInBurst-NES[1100 0000]}”. In this case, UE 600 can monitor first type SSBs (e.g., SSB#0 and SSB#1) for physical downlink control channel detection, beam failure detection, beam failure recovery, and radio link monitoring. Furthermore, UE 600 can monitor both first and second type SSBs for time / frequency synchronization and CSI measurements.

[0144] In this case, UE 600 does not need to perform CSI measurements and reporting for Type 2 SSBs (e.g., SSB#2 to SSB#7). Furthermore, UE 600 does not perform CSI measurements and reporting for CSI-RS 0 to CSI-RS11, which have quasi-co-located relationships with Type 2 SSBs.

[0145] In one embodiment, Figure 10 In this scenario, network node 800 can transmit only one bitmap to a traditional UE (e.g., Figure 8D (Traditional UE 899 in China).

[0146] For example, a conventional UE is configured with a period P0 and a bitmap characterized as “mediumBitmap{ssb-PositionsInBurst[1100 0000]}”.

[0147] In this case, the traditional UE can communicate with the NES cell through one of the first type SSBs (e.g., SSB#0 or SSB#1) and report the selection result to the network node 800.

[0148] In addition, a traditional UE can perform a measurement on a first type of SSB (e.g., SSB#0 or SSB#1) and select one of the first type of SSBs, and then report the selection result to the network node 800.

[0149] Therefore, traditional UEs will not be affected by the specification because Type 1 SSB transmission remains the same in both Phase 1 910 and Phase 920.

[0150] See Figure 13 Its display is based on Figure 10 A schematic diagram of no SSB transmission in the second period.

[0151] exist Figure 13 In the first period 910, network node 800 may transmit a first SSB burst 1010 in a first cycle (e.g., P0), wherein the first SSB burst 1010 may include Figure 9 SSB#0 to SSB#7.

[0152] However, network node 800 may not transmit any SSB bursts in the second phase 920 (i.e., SSB#0 to SSB#7 are not transmitted).

[0153] In some embodiments, Figure 13 The scenario can be applied to specific situations, such as short cell DTX shutdown duration (i.e., shorter second period 920) and / or auxiliary cell without SSB, but the invention is not limited thereto. In this case, the traditional UE may not need to... Figure 13 It is supported in contexts.

[0154] See Figure 14 Its display is based on Figure 13 A schematic diagram of UE behavior in the first and second periods.

[0155] exist Figure 14 In the first period 910, UE 600 can be configured / indicated by a first bitmap characterized as “mediumBitmap{ssb-PositionsInBurst-NES[1111 1111]}”, with a first period of P0. In this case, UE 600 can monitor the first and second types of SSBs for time / frequency synchronization, CSI measurement, and physical downlink shared channel reception. In addition, UE 600 can monitor the first type of SSB for physical downlink control channel detection, beam failure detection, beam failure recovery, and radio link monitoring, but the invention is not limited thereto.

[0156] In the second phase 920, UE 600 can be configured / indicated by a second bitmap characterized as “mediumBitmap{ssb-PositionsInBurst-NES[0000 0000]}”. In this case, UE 600 may not monitor any SSB for time / frequency synchronization, CSI measurement, physical downlink control channel detection, beam failure detection, beam failure recovery, and radio link monitoring.

[0157] In some embodiments, network node 800 may transmit a first type of SSB and a subset of the first type of SSB to handle different coverage areas with different traffic loads.

[0158] See Figure 15A It shows a schematic diagram of configuring SSB transmission patterns in response to traffic load according to an embodiment of the present invention.

[0159] exist Figure 15A In this invention, the first period T0 and T2 can be, for example, the duration of cell DTX on, and the second period T1 and T3 can be, for example, the duration of cell DTX off, but the invention is not limited thereto.

[0160] In this embodiment, assuming that the traffic load in the first beam coverage area CV0 is high and the traffic load in the first beam coverage area CV1 is low during the first period T0, network node 800 may transmit a first SSB burst 1510 in a first period (e.g., P0) during the first period T0, wherein the first SSB burst 1510 may include Figure 9 SSB#0 to SSB#4.

[0161] In this case, the transmitted SSB#0 and SSB#2 through SSB#4 can be used to handle the high-volume load in the first beam coverage area CV0.

[0162] On the other hand, the already transmitted SSB#1 is sufficient to handle the low-volume load in the first beam coverage area CV1, so SSB#5 to SSB#7 do not need to be transmitted.

[0163] See Figure 15B Its display is based on Figure 15A A schematic diagram illustrating the CSI measurements and reporting performed during the first phase.

[0164] In an embodiment, during the first period T0, the UE 600 may use CSI-RS 0 to CSI-RS 5, which have quasi-co-located relationships with SSB#2 to SSB#4, to perform CSI measurements and reports.

[0165] In addition, UE 600 can perform CSI measurements and reporting without using CSI-RS 6 to CSI-RS11, which have quasi-co-located relationships with SSB#5 to SSB#7.

[0166] See Figure 16A Its display is based on Figure 15A A schematic diagram of UE behavior in the first period.

[0167] exist Figure 16A In the first period T0, UEs 1610 and 1620 (e.g., NES UEs) can be configured / indicated to have a first bitmap characterized as “mediumBitmap{ssb-PositionsInBurst-NES[11111000]}” with a first period P0. In this case, UEs 1610 and 1620 can monitor first type SSBs (e.g., SSB#0 and SSB#1) for physical downlink control channel detection, beam failure detection, beam failure recovery, and radio link monitoring. Furthermore, UEs 1610 and 1620 can monitor SSB#0 through SSB#4 for time / frequency synchronization, CSI measurement, and physical downlink shared channel reception, but the invention is not limited thereto.

[0168] exist Figure 16A In this scenario, UE 1610 can use SSB#2, and UE 1620 can use SSB#1. Since UE 1620 uses SSB#1, UE 1620 does not need to monitor SSB#5 to SSB#7 for time / frequency synchronization and CSI measurements, but the present invention is not limited thereto.

[0169] See Figure 16B Its display is based on Figure 16A A schematic diagram of UE behavior during the second period.

[0170] exist Figure 16B In the second period T1 and / or T3, UE 1610 can configure / indicate a second bitmap characterized as “mediumBitmap{ssb-PositionsInBurst-NES[1100 0000]}” with a second period P1. That is, network node 800 can transmit a second SSB burst 1520 including SSB#0 and SSB#1.

[0171] In this embodiment, UE 1610 may monitor first-type SSBs (e.g., SSB#0 and SSB#1) in the second periods T1 and / or T3 for physical downlink control channel detection, beam failure detection, beam failure recovery, and radio link monitoring. Furthermore, UE 1610 may monitor first-type SSBs (e.g., SSB#0 and SSB#1) in the second periods T1 and / or T3 for time / frequency synchronization and CSI measurement.

[0172] In this embodiment, UE 1610 is not required to perform CSI measurements and reporting on the second type SSB (e.g., SSB#2 to SSB#7) during the second period T1 and / or T3. Furthermore, UE 1610 does not perform CSI measurements and reporting on CSI-RS 0 to CSI-RS 11, which have a quasi-co-located relationship with the second type SSB, during the second period T1 and / or T3.

[0173] exist Figure 16B In this case, it is assumed that UE 1610 uses SSB#0 in the second period T1 and / or T3. In this case, UE 1610 may not need to monitor SSB#2 to SSB#7 for time / frequency synchronization and CSI measurements in the second period T1 and / or T3.

[0174] See Figure 17A Its display is based on Figure 15A A diagram illustrating the configuration of SSB transport patterns in response to traffic load.

[0175] Assuming that the traffic load is low in the first beam coverage area CV0 and high in the first beam coverage area CV1 during the first period T2, network node 800 may transmit a first SSB burst 1710 in the first period T2 with a first cycle (e.g., P0), wherein the first SSB burst 1710 may include Figure 9 SSB#0, SSB#1, and SSB#5 through SSB#7.

[0176] In this case, the transmitted SSB#1 and SSB#5 to SSB#7 can be used to handle the high-flow load in the first beam coverage area CV1 during the first period T2.

[0177] On the other hand, the transmitted SSB#0 is sufficient to handle the low traffic load in the first beam coverage area CV0, so SSB#2 to SSB#4 do not need to be transmitted in the first period T2.

[0178] See Figure 17B Its display is based on Figure 17A A schematic diagram of UE behavior in the first period.

[0179] exist Figure 17B In the first period T2, UE 1610 can configure / indicate the first period P0 and the first bitmap characterized as “mediumBitmap{ssb-PositionsInBurst-NES[1100 0111]}”. In this case, UE 1610 can monitor the first type of SSB (e.g., SSB#0 and SSB#1) in the first period T2 for physical downlink control channel detection, beam failure detection, beam failure recovery, and radio link monitoring. In addition, UE 1610 can monitor SSB#0, SSB#1, and SSB#5 to SSB#7 in the first period T2 for time / frequency synchronization, CSI measurement, and physical downlink shared channel reception, but the invention is not limited thereto.

[0180] exist Figure 17B In this scenario, UE 1610 can use SSB#0 in the first period T2. Since UE 1610 uses SSB#0, UE 1610 does not need to monitor SSB#2 to SSB#4 for time / frequency synchronization and CSI measurement in the first period T2, but the present invention is not limited thereto.

[0181] In the embodiment, network node 800 in the scenarios of Figures 15 to 17 may transmit only one bitmap to the traditional UE (e.g., Figure 8D (Traditional UE 899 in China).

[0182] For example, a traditional UE can be configured with a period P0 and a bitmap characterized as “mediumBitmap{ssb-PositionsInBurst[1100 0000]}”.

[0183] In this case, a conventional UE can monitor the first type of SSB (e.g., SSB#0 and SSB#1) for time / frequency synchronization and CSI measurements.

[0184] In addition, a conventional UE can measure the first type of SSB (e.g., SSB#0 and SSB#1), select one of the first type of SSB, and report the selection result to the network node 800 accordingly.

[0185] Therefore, traditional UEs will not be affected by the specification because the first type of SSB transmission remains the same in the first period T0, T2 and the second period T1, T3.

[0186] In some embodiments of the present invention, network node 800 may preset the transmission of a first SSB set. That is, network node 800 may be configured to operate continuously by following the mechanism corresponding to the first period in the above embodiments.

[0187] In this case, network node 800 can switch from transmitting the first SSB set to transmitting the second SSB set under certain specific conditions. That is, network node 800 can be configured to switch to operation by following the mechanism corresponding to the second period in the above embodiments under certain specific conditions.

[0188] See Figure 18 The embodiment of the invention shows a schematic diagram of switching between transmitting a first SSB set in a first period and transmitting a second SSB set in a second period.

[0189] exist Figure 18 In the second period 1810 and / or 1830, network nodes may transmit a second SSB set (e.g., Figure 9 The NES UE can be configured to receive the second set of SSBs (SSB#0 and SSB#1) by default.

[0190] In one embodiment, a network node may decide to switch from transmitting the second SSB set in the second period 1810 to transmitting the first SSB set in the first period 1820 (e.g., Figure 9 (SSB#0 to SSB#7 in the first period). In this case, the network node may send a first SSB indicator SID1 to the NES UE before the first period 1820, wherein the first SSB indicator SID1 may indicate the activation of the first SSB set (e.g., SSB#0 to SSB#7).

[0191] Therefore, the NES UE can perform a first communication operation (e.g., SSB reception) for the first period 1820 according to the first SSB indicator SID1.

[0192] In embodiments of the present invention, the activation and / or deactivation of the first period 1820 can be determined in various ways.

[0193] See Figure 19 Its display is based on Figure 18 A diagram illustrating the different options for starting and / or stopping the first phase.

[0194] In Option 1, the NES UE may receive a second SSB indicator SID2 to stop performing the first communication operation during the first period 1910. That is, the NES UE may switch from receiving the first SSB set (e.g., SSB#0 to SSB#7) to receiving the second SSB set (e.g., SSB#0 and SSB#1) in response to receiving the second SSB indicator SID2. In Option 1, the NES UE may begin receiving the first SSB set (e.g., SSB#0 to SSB#7) during the first period 1910 after receiving the first SSB indicator SID1. And the NES UE may stop receiving the first SSB set (e.g., SSB#0 to SSB#7) during the first period 1910 after receiving the second SSB indicator SID2.

[0195] In some embodiments, the second SSB indicator SID2 may be downlink control information signaling, media access control control element, or radio resource control signaling.

[0196] In option 2, the first SSB indicator SID1 can initiate transmission of the first SSB set (e.g., SSB#0 to SSB#7) in the first period 1920. Transmission of the first SSB set (e.g., SSB#0 to SSB#7) in the first period 1920 can be deactivated after a time duration (e.g., B), where the time duration (e.g., B) can be pre-configured, fixed, configurable, or indicated by the first SSB indicator SID1. That is, the first SSB indicator SID1 can carry information about the time duration (e.g., B) of the first period 1920. In response to the time duration (e.g., B), the NES UE can accordingly determine the end time of the first period 1920. In this case, in response to determining that the end time of the first period 1920 has arrived, the NES UE can stop performing the first communication operation during the first period 1920. In other words, the NES UE can switch from receiving the first SSB set (e.g., SSB#0 to SSB#7) to receiving the second SSB set (e.g., SSB#0 and SSB#1) in response to the end time of the first period 1920.

[0197] In Option 3, the first SSB indicator SID1 can initiate the transmission of the first SSB set (e.g., SSB#0 to SSB#7) in the first period 1930. The transmission of the first SSB set (e.g., SSB#0 to SSB#7) in the first period 1930 can be deactivated after a number of first SSB bursts (e.g., W) have been transmitted, wherein the number of first SSB bursts (e.g., W) can be pre-configured, fixed, configurable, or indicated by the first SSB indicator SID1. In Option 3, the NES UE can begin receiving the first SSB set (e.g., SSB#0 to SSB#7) in the first period 1930 after the NES UE receives the first SSB indicator SID1. And the NES UE can stop receiving the first SSB set (e.g., SSB#0 to SSB#7) in the first period 1930 after the NES UE receives W first SSB bursts. In response to the number of first SSB bursts (e.g., W), if W first SSB bursts have been transmitted (e.g., in... Figure 19 If W=2), the NES UE may stop performing the first communication operation during the first period 1930. That is, the NES UE may switch from receiving the first SSB set (e.g., SSB#0 to SSB#7) to receiving the second SSB set (e.g., SSB#0 and SSB#1) after W first SSB bursts have been transmitted.

[0198] In embodiments that transmit a first SSB indicator SID1 and / or a second SSB indicator SID2, the NES UE can receive an SSB by following the SSB pattern indicated in the first SSB indicator SID1 and / or the second SSB indicator SID2.

[0199] For example, when the NES UE receives the first SSB indicator SID1 indicating SSB#0 to SSB#7, the NES UE may accordingly receive SSB#0 to SSB#7 during, for example, a first period 1910 (which may be a period corresponding to high traffic load).

[0200] Furthermore, when the NES UE receives the second SSB indicator SID2 indicating SSB#0 to SSB#4, the NES UE can accordingly receive SSB#0 to SSB#4 in the period following the first period 1910 (which may be one or more periods corresponding to low traffic load).

[0201] See Figure 20 Its display is based on Figure 18 and Figure 19 A schematic diagram of UE behavior.

[0202] exist Figure 20In the second phase 1810, network nodes can preset the transmission of the second SSB burst 2020 (which includes SSB#0 and SSB#1).

[0203] In an embodiment, a network node may send a first SSB indicator SID1 to the NES UE, wherein the first SSB indicator SID1 may indicate the initiation of a first SSB burst 2010 (which includes SSB#0 to SSB#7).

[0204] After the first phase 1820 ends, network nodes can transmit the second SSB burst 2020 (which includes SSB#0 and SSB#1) again in the second phase 1830.

[0205] In an embodiment, the NES UE may use SSB#0 to SSB#7 for at least one of physical downlink control channel monitoring and physical downlink shared channel reception.

[0206] In one embodiment, if the NES UE monitors a second type of SSB (e.g., SSB#2 to SSB#7) for at least one physical downlink control channel, it may be associated with a first type of SSB (e.g., SSB#0 and SSB#1) when needed.

[0207] exist Figure 20 In the second period 1810 and 1830 (which can be understood as a preset period), the NES UE configuration / indicator has a second bitmap characterized as “mediumBitmap{ssb-PositionsInBurst-NES[11000000]}” with a second period of P1.

[0208] In this case, the NES UE can monitor the first type of SSB (e.g., SSB#0 and SSB#1) in the second period 1810 and 1830 for time / frequency synchronization, physical downlink control channel monitoring, and / or physical downlink shared channel reception.

[0209] In addition, NES UEs may not monitor second-type SSBs (e.g., SSB#2 to SSB#7) for time / frequency synchronization, physical downlink control channel monitoring, and / or physical downlink shared channel reception in the second periods 1810 and 1830.

[0210] The NES UE can communicate with the NES cell via a first type SSB (e.g., SSB#0 and SSB#1) during the second periods 1810 and 1830, and the NES UE can monitor the first type SSB for CSI measurement, beam failure detection, beam failure recovery, and radio link monitoring during the second periods 1810 and 1830.

[0211] On the other hand, for the first period 1820 (which can be understood as the indication period), the NES UE configuration / indication has a first bitmap characterized as “mediumBitmap{ssb-PositionsInBurst-NES[1111 1111]}” with a first period of P0.

[0212] In this case, the NES UE can monitor first-type SSBs and second-type SSBs (e.g., SSB#0 to SSB#7) in the first period 1820 for time / frequency synchronization, physical downlink control channel monitoring, and / or physical downlink shared channel reception.

[0213] The NES UE can communicate with the NES cell via a first type SSB and a second type SSB (e.g., SSB#0 to SSB#7) during the first period 1820, and the NES UE can monitor the first type SSB and the second type SSB (e.g., SSB#0 to SSB#7) during the first period 1820 for CSI measurement, beam failure detection, beam failure recovery, and radio link monitoring.

[0214] In an embodiment, during the first period 1820, the NES UE may use CSI-RS (e.g., with quasi-co-addressable relationships to SSB#2 through SSB#7) Figure 11B CSI-RS 0 to CSI-RS 11 perform CSI measurements and reports, and a schematic diagram can be found in the diagram. Figure 11B .

[0215] exist Figure 20 In this scenario, if the NES UE communicates with the NES cell via a second type SSB (e.g., SSB#2) during the first period 1820 (i.e., the indication period), the NES UE is aware that it can fall back to the corresponding first type SSB (e.g., SSB#0, which has a quasi-co-located relationship with SSB#2) after the first period 1820 ends. For example, the reference signal for the transmission configuration indication state can be changed from SSB#2 to SSB#0, and the transmission configuration indication state of the control resource set can be changed from SSB#2 to SSB#0.

[0216] In some embodiments, the first SSB indicator SID1 may carry different bit combinations corresponding to different SSB combinations, which may be exemplarily shown in Table 1 below.

[0217]

[0218] Table 1

[0219] See Figure 21 It shows a schematic diagram of using different cycles in the first and second periods according to an embodiment of the present invention.

[0220] exist Figure 21 In this context, the second period (e.g., P1) can be K times the first period (e.g., P0), where K can be a positive integer. In this case, the mechanism for transmitting CSI reports in the first period 2110 and the second period 2120 can be implemented in different ways.

[0221] See Figure 22 Its display is based on Figure 21 A schematic diagram of the CSI report transmission mechanism.

[0222] exist Figure 21 In the first period 2110, the UE can transmit the corresponding CSI report at time points T00, T00+N, T00+2N and T00+3N (N is the period).

[0223] However, the strategy for the UE to transmit CSI reports during the second period 2120 may differ among different options.

[0224] In Option 1, if no updated CSI report is determined, the UE may not transmit the CSI report. For example, if the CSI report determined at time point T00+4N is the same as the CSI report determined at time point T00+3N, the UE may not transmit the CSI report at time point T00+4N. Similarly, if the CSI report determined at time point T00+6N is the same as the CSI report determined at time point T00+5N, the UE may not transmit the CSI report at time point T00+6N. Likewise, if the CSI reports determined at time points T00+8N and T00+9N are the same as the CSI report determined at time point T00+7N, the UE may not transmit the CSI reports determined at time points T00+8N and T00+9N.

[0225] In Option 2, if no updated CSI report is determined, the UE may transmit the previous CSI report. For example, if the CSI report determined at time point T00+4N is the same as the CSI report determined at time point T00+3N, the UE may retransmit the corresponding CSI report for time point T00+3N at time point T00+4N. Similarly, if the CSI report determined at time point T00+6N is the same as the CSI report determined at time point T00+5N, the UE may retransmit the corresponding CSI report for time point T00+5N at time point T00+6N. Likewise, if the CSI reports determined at time points T00+8N and T00+9N are the same as the CSI report determined at time point T00+7N, the UE may retransmit the corresponding CSI report for time point T00+7N at time points T00+8N and T00+9N.

[0226] In option 3, the UE may use different periods to transmit CSI reports in the first period 2110 and the second period 2120, and the resources used for transmitting CSI reports in the first period 2110 and the second period 2120 are the same physical uplink control channel resources. For example, the period for transmitting CSI reports in the first period 2110 may be N, and the period for transmitting CSI reports in the second period 2120 may be M. In this case, for the second period 2120, the UE may transmit CSI reports at time points T11 and T11+M, but the invention is not limited thereto.

[0227] In option 4, the UE can use different periods to transmit CSI reports in the first period 2110 and the second period 2120, but the resources used for transmitting CSI reports in the first period 2110 and the second period 2120 can be different physical uplink control channel resources. For example, the period for transmitting CSI reports in the first period 2110 can be N, and the period for transmitting CSI reports in the second period 2120 can be M. In this case, for the second period 2120, the UE can transmit CSI reports at time points T11 and T11+M, but the invention is not limited to this.

[0228] In option 5, the UE may transmit any CSI reports non-periodically during the second period 2120. On the other hand, the transmission of CSI reports in the second period 2120 may be non-periodic.

[0229] In this embodiment of the invention, the UE's SSB monitoring and CSI measurement / reporting can be configured in different styles.

[0230] See Figure 23 The present invention illustrates, according to an embodiment of the invention, the configuration of SSB monitoring and CSI measurement / reporting using different styles.

[0231] exist Figure 23 In this configuration, the SSB monitoring of UE 600 can be configured using a first pattern, which can be [1111 1111] to indicate SSB#0 to SSB#7. Therefore, UE 600 can monitor SSB#0 to SSB#7.

[0232] Furthermore, the CSI measurement / reporting of UE 600 can be configured by a second pattern, which can be [1111 1000] to indicate CSI-RS 0 to CSI-RS 5 that have quasi-co-address relationships with SSB#0 to SSB#4. Therefore, UE 600 can perform CSI measurements and reporting for CSI-RS 0 to CSI-RS 5, but not for CSI-RS 6 to CSI-RS11.

[0233] In one embodiment, considering periodic CSI-RS measurements / reports used for CSI acquisition (e.g., channel quality indicator, rank indicator, precoding matrix indicator), the UE 600 can perform the following in a first period (e.g. Figure 21 In the first phase (2110), monitoring corresponds to CSI-RS resources, but in the second phase (e.g.) Figure 21 During the second phase (2120), the corresponding CSI-RS resources are not monitored.

[0234] For the first period (e.g., cell DTX on-time duration or indication period), if the corresponding bits in both the first and second styles indicate, for example, '1', the UE 600 can receive / monitor the corresponding CSI-RS resource for CSI acquisition.

[0235] In addition, UE 600 can execute CSI reports associated with CSI report configuration IDs.

[0236] On the other hand, if the corresponding bits in both the first and second patterns indicate, for example, '0', the UE 600 may not receive / monitor the corresponding CSI-RS resource for CSI acquisition. Furthermore, the UE 600 may not execute the CSI report associated with the CSI report configuration ID (e.g., ignore the CSI report configuration ID).

[0237] In one embodiment, an aperiodic CSI report may be triggered to the UE 600 if necessary.

[0238] For the second period (e.g., cell DTX off duration or preset period), if the corresponding bits in both the first and second styles indicate '1' or '0', the UE 600 may not receive / monitor the corresponding CSI-RS resources for CSI acquisition. Furthermore, the UE 600 may not execute the CSI report associated with the CSI report configuration ID (e.g., ignore the CSI report configuration ID).

[0239] In one embodiment, considering periodic CSI-RS measurements / reports for beam management (e.g., reference signal received power, reference signal received quality), the UE 600 can monitor the corresponding CSI-RS resources in a first period and a second period.

[0240] For the first period (e.g., cell DTX on duration or indication period) and the second period (e.g., cell DTX off duration or preset period), if the corresponding bits in both the first and second patterns indicate, for example, '1', the UE 600 can receive / monitor the corresponding CSI-RS resources for beam management. Furthermore, the UE 600 can execute a CSI report associated with the CSI report configuration ID.

[0241] On the other hand, if the corresponding bits in both the first and second patterns indicate, for example, '0', the UE 600 may not receive / monitor the corresponding CSI-RS resources for beam management. Furthermore, the UE 600 may not execute the CSI report associated with the CSI report configuration ID (e.g., ignore the CSI report configuration ID).

[0242] In one embodiment, if UE 600 communicates with the NES cell via CSI-RS#n, it also knows that UE 600 can fall back to SSB#k according to the first and second patterns (if CSI-RS#n and SSB#k have a quasi-co-address relationship). For example, the transmission configuration indication state reference signal changes from CSI-RS#n to SSB#k, where CSI-RS#n and SSB#4 have a quasi-co-address relationship. Therefore, the control resource set transmission configuration indication state changes from CSI-RS#n to SSB#4.

[0243] See Figure 24 This illustrates another schematic diagram showing the configuration of SSB monitoring and CSI measurement / reporting using different styles according to embodiments of the present invention.

[0244] exist Figure 24 In this configuration, UE 600SSB monitoring can be configured using a first style, which can be [1111 1111] to indicate SSB#0 to SSB#7. Therefore, the NES UE can monitor SSB#0 to SSB#7.

[0245] Furthermore, the NES UE's CSI measurements / reports can be configured using a second style, which can be [1111 0000] to indicate CSI-RS 0 to CSI-RS 7, which have quasi-co-address relationships with SSB#0 to SSB#3. Therefore, the NES UE can perform CSI measurements and reports for CSI-RS 0 to CSI-RS 7, but not for CSI-RS 8 to CSI-RS 15.

[0246] In summary, this invention achieves flexible control of network-side energy consumption by configuring hybrid SSB types, including a first type SSB with a larger coverage area and a second type SSB with a smaller coverage area. Compared with the traditional on-demand SSB transmission scheme that relies on network-triggered activation, the proposed hybrid SSB transmission strategy allows the network to use only the first type SSB to maintain time and frequency synchronization with the UE during energy-saving operation periods, while disabling the second type SSB to reduce transmission power.

[0247] This approach allows the network to achieve longer idle periods without transmitting multiple SSBs, thereby enhancing overall power efficiency. This hybrid SSB configuration offers a balance between synchronization reliability and energy performance, making it particularly effective when transitioning between high-density and low-traffic scenarios, supporting dynamic energy adaptation and system optimization.
