[0058] Figure 1 Examples of application scenarios 100 in which some exemplary embodiments of the present disclosure may be implemented are illustrated. Application scenario 100 (which is part of a communication network) includes terminal devices and network devices.

[0059] In the description of the exemplary embodiments of this disclosure, network environment 100 may also be referred to as communication system 100 (e.g., part of a communication network). Communication system 100 may be a non-terrestrial or terrestrial system.

[0060] For illustrative purposes only, various aspects of the example embodiments will be described in the context of one or more terminal devices and network devices communicating with each other. However, it should be understood that the description herein can be applied to other types of devices or other similar devices referred to using other terms.

[0061] like Figure 1 As shown, the communication network 100 may include network device 110 (which may also be referred to as eNB, gNB, or BS). The communication network 100 may also include terminal device 120 (which may also be referred to as user equipment 120 or UE 120). Although... Figure 1 Only one network device 110 and one terminal device 120 are shown, but the number of network devices and terminal devices is unlimited. In other words, there can be one or more network devices 110 and one or more terminal devices 120 in the network.

[0062] Network device 110 can provide services to terminal device 120, and network device 110 and terminal device 120 can transmit data and control information to each other. In some embodiments, network device 110 and terminal device 120 can communicate via a direct link / channel.

[0063] In communication system 100, the link from network device 110 to terminal device 120 is called the downlink (DL), and the link from terminal device 120 to network device 110 is called the uplink (UL). In the downlink, network device 110 is a transmitting (TX) device (or transmitter), and terminal device 120 is a receiving (RX) device (or receiver). In the uplink, terminal device 120 is a transmitting (TX) device (or transmitter), and network device 110 is an RX device (or receiver). It should be understood that network device 110 can provide one or more serving cells. Figure 1 As shown, network device 110 provides a serving cell 102, and terminal device 120 resides on serving cell 102. In some embodiments, network device 110 may provide multiple serving cells, and terminal device 120 may switch between serving cells from a source cell to a target cell during its movement.

[0065] It should be understood that Figure 1 The number of devices, their connections, and types shown are for illustrative purposes only and do not represent any limitation. Communication system 100 may include any suitable number of devices appropriate for implementing embodiments of this disclosure.

[0066] The work item for network power saving in Rel-19 has been approved. It is agreed to specify (multiple) procedures and signaling methods in Rel-19 to support UE operation in connected modes with Carrier Aggregation (CA) configured for both in-band and inter-band CA. Considering factors such as... Figure 2 The different OD-SSB scenarios shown are consistent with the following premise. Specifically, scenario 1 assumes there is no regular SSB transmission in the SCell and OD-SSB can only be triggered from time to time. Scenario 2 assumes there is always-on SSB (AO-SSB) transmission in the SCell and on-demand SSB can be triggered additionally.

[0067] For the established scenarios and conditions, the gNB can trigger OD-SSB in at least the following scenarios / conditions: Scenario #2 and Condition #1, Scenario #2 and Condition #2, Scenario #2A and Condition #1, and Scenario #2A and Condition #2. Scenario #2A refers to "when the UE receives the SCell activation command (e.g., as defined in TS 38.321)," and Scenario #3A refers to "after the UE receives the SCell activation command (e.g., as defined in TS 38.321), until SCell activation is complete." Scenario 3B refers to "when SCell activity is complete and the SCell is activated" or "after SCell activation is complete and the SCell is activated."

[0068] like Figure 3 As shown, there are several possible scenarios regarding the relationship between AO-SSB and OD-SSB in Case 2, including: - Scenario 1 (i.e., Figure 3 Case 2-1): OD-SSB and AO-SSB have the same frequency and the same offset but different periods. - Scenario 2 (i.e., Figure 3 Case 2-2): OD-SSB and AO-SSB have the same frequency, different offsets, and different periods. - Scenario 3 (i.e., Figure 3 Cases 2-3): OD-SSB and AO-SSB are at different frequencies.

[0069] Regarding the timing of the UE's expected transmission of OD-SSB bursts from the network, the following is agreed upon. For multiple SSB bursts indicated by MAC CE via OD-SSB SCell operation, the UE expects to send multiple on-demand SSB bursts from time instance A, which is determined as follows. - Time instance A is the start of the first time slot containing the on-demand SSB burst [candidate SSB index 0 or first actually transmitted SSB index], which is at least T after the UE receives signaling from the gNB indicating on-demand SSP transmission. The SSB time domain location of the on-demand SSB burst is configured by the gNB. - The value of T is not less than the existing timeline required for SCell activation and UE MAC CE processing. - T is not less than Where time slot n+m is the time slot used for PUCCH transmission indicated by HARQ-QCK information when the UE receives MAC CE signaling to indicate the end of on-demand SSB transmission in time slot n. As defined in the current specification. The above applies at least to SCells with on-demand SSB transmission and cells with signaling transmission that use the same digital technology.

[0070] It is agreed that Tmin is expressed as MAC processing time, that is, 3ms plus the time used to reply to the MAC command with a Hybrid Automatic Repeat Request (HARQ), i.e., T HARQ This is the same timing used for receiving the SCell activation MAC CE. However, some additional processing time may be required to receive the first OD-SSB. The UE may need additional implementation work to receive the OD-SSB and needs time to adjust the advance time of measurements on the OD-SSB. Considering different UE implementations, additional processing time may be required in some cases, but OD-SSB-based measurements do not always require additional processing time. Therefore, some UE requirement needs to be specified on the UE side to prepare for receiving the first OD-SSB burst after receiving the OD-SSB activation command.

[0071] This disclosure targets objects related to OD-SSB transmission, specifically how Radio Resource Management (RRM) requirements are affected by processing time. This disclosure proposes defining UE requirements, such as an OD-SSB activation delay. This is a time period during which the UE should be prepared (able) to receive the first OD-SSB burst after receiving an OD-SSB (e.g., MAC CE) activation command. The OD-SSB activation delay can be determined based on the type of message indicating OD-SSB activation, the OD-SSB SCell or cell state, and the relationship between always-on SSBs and OD-SSBs. The OD-SSB activation delay requirement applies if the UE needs to receive the OD-SSB in response to an OD-SSB (MAC CE) activation command. Therefore, the UE should be able to receive the (OD-)SSB no later than the defined activation delay. Note that in this disclosure, the terms "OD-SSB activation" and "OD-SSB triggering" are used interchangeably.

[0072] This disclosure generally addresses issues involving SCells. However, this is only a non-limiting example and it must be understood that the principle can be applied to any cell, such as a primary cell (PCell), a primary-secondary cell (PSCell), or an SCell.

[0073] The OD-SSB activation delay may include a basic processing time based on the message type of the OD-SSB activation. If the OD-SSB activation is indicated by a MAC command, the OD-SSB activation delay includes: the MAC CE processing time Tmin, and an additional processing time determined based on the OD-SSB SCell scenario and whether the OD-SSB is triggered on a SCell without an AO-SSB or on a measurement SCell (with an AO-SSB).

[0074] If OD-SSB activation is caused by Radio Resource Control (RRC) messages (e.g., RRCReconfiguration If the OD-SSB activation indication is given, the activation delay includes: the RRC process or processing delay, the time to send the RRC message in response to the OD-SSB activation indication, and additional processing time, which is determined based on the OD-SSB SCell scenario and whether the OD-SSB is triggered on a SCell without an AO-SSB or on a measurement SCell (with an AO-SSB).

[0075] If OD-SSB activation is indicated by downlink control information (DCI), the activation delay includes: DCI processing time and additional processing time, which is determined based on the OD-SSB SCell scenario and whether the OD-SSB is triggered on a SCell without an AO-SSB or on a measurement SCell (with an AO-SSB).

[0076] Similarly, when SSB adaptation is enabled, UE requirements also apply, such as what is termed an SSB adaptation delay. The UE should be at least prepared (able to) receive the first SSB burst after the SSB adaptation delay, either after receiving a message triggering SSB adaptation or after determining that SSB adaptation should be performed (e.g., based on the occurrence of an event). The SSB adaptation delay can further consider the SSB configuration before and after adaptation. The UE can indicate the length of the additional processing time based on its implementation. Therefore, UE requirements are determined based on UE capabilities.

[0077] Figure 4 An example of a process flow 400 for OD-SSB activation delay according to some exemplary embodiments of the present disclosure is illustrated. For ease of understanding, reference will be made to... Figure 1 Describe the processing flow 400. It should be understood that, although referenced... Figure 1 The communication network 100 has already described the process flow 400, but the process flow 400 can also be applied to other similar communication scenarios.

[0078] At 401, network device 110 (which may be interchangeably referred to as "NW") sends OD-SSB triggering signaling 402 for the cell to terminal device 120 (which may be interchangeably referred to as "UE"). Therefore, at 403, terminal device 120 receives OD-SSB triggering signaling 402 from network device 110. The state of the cell on which OD-SSB is transmitted can be PCell, PSCell, or SCell. OD-SSB triggering signaling 402 can be RRC signaling, MAC CE, or DCI.

[0079] At 404, terminal device 120 determines an OD-SSB trigger delay. After this OD-SSB trigger delay, the terminal device is ready to monitor or receive the first OD-SSB in an OD-SSB burst following the reception of the OD-SSB trigger signaling. In some embodiments, terminal device 120 may determine the OD-SSB trigger delay based on at least one of the following: the message type of the OD-SSB trigger signaling 402, the state of the cell on which the OD-SSB is received, or the relationship between the OD-SSB and the AO-SSB. In some embodiments, the terminal device is not required to monitor or receive an OD-SSB within the OD-SSB trigger delay following the reception of the OD-SSB trigger signaling.

[0080] At point 405, network device 110 determines the OD-SSB trigger delay. After this OD-SSB trigger delay, the terminal device is ready to monitor or receive the first OD-SSB in the OD-SSB burst following the reception of the OD-SSB trigger signaling. Therefore, terminal device 120 and network device 110 can have common knowledge regarding the trigger delay. Although embodiments related to the determination of the trigger delay are described from the perspective of terminal device 120 in this disclosure, it should be understood that it also applies to network device 110. In this way, both the UE side and the network side are aware of the timing used to receive the first OD-SSB.

[0081] Figure 5 The illustration shows a schematic diagram of the additional processing time for OD-SSB activation according to some example embodiments of the present disclosure.

[0082] like Figure 5 As shown, the OD-SSB triggering delay from OD-SSB activation to the first OD-SSB burst can include the basic processing time (Tmin) and the additional processing time (T) for adapting the terminal device to monitor or receive the OD-SSB. Add_Proc This additional processing time can be determined based on the OD-SSB cell status and the relationship between AO-SSB and OD-SSB.

[0083] In one respect, additional processing time can be applied and included in the trigger delay if any of the following conditions are met (this can be applied to both case 1 and case 2): - If the UE did not receive any AO-SSB or OD-SSB from the SCell before or after the SCell was added, this means that the UE first received an SSB from the SCell when the OD-SSB was triggered on the SCell. - If the UE has not recently received any AO-SSB or OD-SSB on the SCell (e.g., within a certain period before receiving the OD-SSB activation command). In this case, if the UE has not measured the SCell within a certain period (e.g., after a previous successful detection / measurement / reception of an OD-SSB), the UE may need additional time to prepare to receive the OD-SSB. This specific time period can be related to the measurement cycle ( MeascycleSCell (or associated with a timer.) - If the SCell (and associated OD-SSB) is not in the same FR2 band as any active serving cell, or is not adjacent to any serving cell in the same FR1 band.

[0084] On the other hand, the additional processing time is determined based on the relationship between AO-SSB and OD-SSB in Case 2. Specifically, additional processing time can be applied and included in the trigger delay if any of the following conditions are met: - If OD-SSB and AO-SSB are on the same carrier frequency (i.e., Figure 3 In case 2-1 / 2-2), no additional processing time is required because the UE has already measured the AO-SSB on the carrier frequency. Alternatively, if the UE is configured with an SSB Measurement Timing Configuration (SMTC) for measuring the OD-SSB and this SMTC is different from the SMTC used for measuring the AO-SSB, the UE may require additional processing time. Otherwise, no additional processing time is required. Alternatively, the UE can determine the required processing time based on the determination of the OD-SSB and the AO-SSB on the cell at different frequency locations on the same carrier frequency. - If the cell's OD-SSB and AO-SSB are on different carrier frequencies (i.e., Figure 3 In cases 2-3), the UE may require additional processing time to receive the OD-SSB. Alternatively, if the OD-SSB is not within the UE Active Bandwidth (BWP) portion that includes the OD-SSB, additional processing time is required. In this case, additional processing time may be necessary to account for at least the BWP handover time for the UE to switch to another BWP to receive the OD-SSB. - If the Physical Cell Identifiers (PCIs) of AO-SSB and OD-SSB are different, additional processing time is considered or allowed; if the PCIs are the same, no additional processing time is required.

[0085] In some embodiments, the additional processing time can be the same regardless of whether the OD-SSB is triggered by DCI, MAC CE, or RRC. The basic processing time can be determined based on the message type of the OD-SSB trigger signaling.

[0086] Additional processing time can be determined based on whether only the MAC CE for the triggering OD-SSB command is received (Scenario 2) or both the MAC CE for the SCell activation command and the MAC CE for the triggering OD-SSB command are received in the same time slot or simultaneously (Scenario 2A) (which means that the additional processing time required for Scenario 2A can be longer than that for Scenario 2).

[0087] The UE determines the required processing time based on the fact that the OD-SSB trigger signaling and the cell activation command are received together in the same message. In other words, if the MAC CE for the Cell activation command and the MAC CE for the triggering OD-SSB command are received in the same message, the trigger delay (Tmin + additional processing time) applies.

[0088] Figure 6 The illustration shows flowcharts illustrating the application of additional processing time in cases 1 and 2 according to some example embodiments of the present disclosure.

[0089] In step 601, the UE receives an SCell reconfiguration message for adding the SCell to the CA operation, wherein the SCell is configured with an OD-SSB. This message may include the OD-SSB configuration for case 1, and may also additionally include the AO-SSB configuration for case 2.

[0090] After adding the message to the SCell, the UE does not need to measure the OD-SSB before receiving the OD-SSB activation command. For case 2, the UE can also monitor the OD-SSB in the SCell.

[0091] In step 602, the UE receives an OD-SSB activation command indicating that an OD-SSB should be sent.

[0092] In step 603, the UE checks whether any of the listed conditions are met. In one example, if the UE has already received the OD-SSB before receiving the OD-SSB activation in step 2, the UE can determine, as shown in step 604, that no additional processing time is required. In another example, if the OD-SSB and AO-SSB are on the same carrier frequency based on the SSB configuration in step 1, the UE can determine that no additional processing time is required. Otherwise, the UE determines in step 605 that additional processing time is required.

[0093] In step 606, the UE can determine the OD-SSB activation delay based on the additional processing time determined in steps 604 and 605, and prepare to receive the OD-SSB after (Tmin + additional processing time). Note that the UE can prepare to receive the OD-SSB well before the activation delay ends.

[0094] In step 607, the UE receives the OD-SSB in the SCell.

[0095] When SSB adaptation is enabled, UE requirements may also apply, such as what is called an SSB adaptation delay. The UE should be at least prepared (able to) receive the first SSB burst after the SSB adaptation delay, either after receiving a message triggering SSB adaptation or after determining that SSB adaptation should be performed. The SSB adaptation delay can further consider the SSB configuration before and after adaptation.

[0096] Figure 7 An example of a process flow 700 for SSB adaptation delay according to some exemplary embodiments of the present disclosure is illustrated. For ease of understanding, reference will be made to... Figure 1 The processing flow is described in section 700. It should be understood that, although referenced... Figure 1 The communication network 100 describes the process flow 700, but the process flow 700 can also be applied to other similar communication scenarios.

[0097] At point 701, network device 110 sends an SSB adaptation command 702 to terminal device 120. The SSB adaptation command 702 can be considered a trigger for SSB adaptation by the terminal device. Therefore, at point 703, terminal device 120 receives the SSB adaptation command 702 from network device 110. In some embodiments, terminal device 120 may determine the trigger for SSB adaptation based on the occurrence of an event at terminal device 120.

[0098] At 704, terminal device 120 determines an SSB adaptation delay. After this SSB adaptation delay, the terminal device is ready to monitor or receive the first SSB in the SSB burst following the triggering of SSB adaptation. In some embodiments, within the SSB adaptation delay following the triggering of SSB adaptation, terminal device 120 does not need to monitor or receive the adapted SSB. In some embodiments, the SSB adaptation delay may be determined based at least on the SSB configuration before and after adaptation.

[0099] At point 705, network device 110 also determines the SSB adaptation delay, after which the terminal device is ready to monitor or receive the first SSB in the SSB burst following the triggering of SSB adaptation. Therefore, terminal device 120 and network device 110 can have common knowledge regarding the SSB adaptation delay. Although embodiments related to the determination of the SSB adaptation delay are described from the perspective of terminal device 120 in this disclosure, it should be understood that it also applies to network device 110. In this way, both the UE side and the network side are aware of the timing used to receive the SSB adaptation.

[0100] In some embodiments, the terminal device may determine whether the processing time required for adapting the terminal device to receive or monitor the adapted SSB is needed in the SSB adaptation delay. If processing time is required, the terminal device 120 may include the processing time in the SSB adaptation delay.

[0101] If SSB adaptation is indicated via MAC CE, the adaptation delay includes the base processing time Tmin and an additional processing time determined based on the SSB configuration before and after adaptation. The additional processing time can be applied (required) and included in the SSB adaptation delay if any of the following conditions are met: - If the SSB is adapted to the same carrier frequency and only has periodic adaptation, no additional processing time is required. If the SSB is adapted to different carrier frequencies, additional processing time is required. - If the power level is adapted after adaptation (e.g., along with the cycle), additional processing time is required. - If a time offset is applied after adaptation, additional processing time is required. Otherwise, no additional processing time is required. - If the spatial relationships change after adaptation, additional processing time will be required. Otherwise, no additional processing time is required.

[0102] In some embodiments, if SSB adaptation is implicitly determined, for example when certain events or conditions are met, the adaptation delay includes only the additional processing time determined above based on the SSB configuration before and after adaptation.

[0103] In some embodiments, the terminal device may send an indication of the length of the processing time to the network device. For example, if the triggering of SSB adaptation is based on the occurrence of a corresponding event locally, the length of the processing time may be notified to the network device, if necessary.

[0104] Figure 8 The diagram illustrates a flowchart of the application of additional processing time for SSB adaptation according to some example embodiments of this disclosure. The UE applies the additional processing time if any one of a set of conditions is met.

[0105] In step 801, the UE receives an SCell reconfiguration message for adding an SCell to the CA operation, wherein the SCell is configured with SSB adaptation features. At least two SSB configurations are configured by the network, and the SSB is sent in an alternative manner based on the SSB adaptation indication message.

[0106] In step 802, after the message is added to the SCell, the UE can monitor the SSB in the SCell, such as SSB#1 (i.e., the SSB before adaptation).

[0107] In step 803, the UE receives an SSB adaptation indication or command that indicates the SSB needs to be adapted (e.g., switched to the second SSB#2 configured by the network).

[0108] In step 804, the UE checks whether any of the above conditions are met. In one example, if the SSB is adapted on the same carrier frequency and has only periodic adaptation, then as shown in step 805, the UE determines that no additional processing time is required. Otherwise, in step 806, the UE determines that additional processing time is required.

[0109] In step 807, the UE determines the SSB adaptation delay based on the additional processing time determined in steps 805 and 806, and is prepared to receive another SSB after SSB adaptation (Tmin plus additional processing time if necessary).

[0110] In step 808, the UE receives the adapted SSB in the SCell.

For ease of understanding, reference will be made to... Figure 1 Method 900 is described from the perspective of terminal device 120.
