[0105] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0106] In some implementations, in intra-band CA and / or inter-band CA, the adaptive SSB may include an on-demand SSB (OD SSB). For connected-mode terminals configured with CA, specified procedures and signaling methods for on-demand SSB SCell operation can be supported. For example, specified triggering methods can be supported, and the following triggering methods can be selected: a terminal uplink wake-up signal using an existing signal / channel, a cell on / off indication via backhaul, or Scell ​​activation / deactivation signaling.

[0107] Specifically, the OD SSB transmission can be used by the terminal for at least one of the following: SCell time / frequency synchronization, L1 / L3 measurements, SCell activation; and the SSB supports frequency ranges 1 (FR1) and FR2 in the non-shared spectrum on demand. For example, during SCell activation, the terminal can perform SCell measurements based on the OD SSB.

[0108] In some implementations, compared to a conventional SSB, the SSB in an OD SSB or OD SSB SCell is not always transmitted; transmission can be reduced based on network or terminal needs, thereby achieving energy savings on the network side. For example, the network device triggers the transmission of an OD SSB based on signaling, and the terminal receives the OD SSB based on this triggering signaling; or, the terminal sends a request to the network device when it needs an SSB, and the network device sends an OD SSB based on the terminal's request. To distinguish it from a conventional SSB, an OD SSB can refer to an OD SSB or an SSB in an OD SSB SCell.

[0109] In some implementations, when the OD SSB is triggered for SCell activation, the OD SSB period can be as short as possible, such as shortening the measurement cycle, enabling the terminal to complete the measurement quickly, thereby improving measurement efficiency and saving network power. The above measurement process is called "fast L3 measurement" in the RAN4 protocol. Referring to Figure 1B, the measurement window corresponding to fast L3 measurement, or fast mode, is called the fast mode window or fast measurement window. This measurement window can also be called a time window.

[0110] For deactivated SCells, compared to activated or soon-to-be-activated SCells, the OD SSB period can be longer or sparser, thereby reducing the frequency of OD SSB measurements by the terminal and saving terminal power consumption. This measurement process can be called "slow measurement". As shown in Figure 1B, the window corresponding to slow measurement is located after the fast measurement window.

[0111] In this embodiment, as shown in Figure 1B, the rapid measurement window can be denoted as T. f (or T) fast The window corresponding to the subsequent slow speed can be denoted as T. s (or T) slow Measurement methods based on OD-SSB timing-balanced power consumption and reliability measurement results may include: in T fast The periodicity of OD-SSB-based measurements is limited, and thereafter, as in T... slow The terminal can perform relaxed measurement or stopped measurement through network-configured parameters. For example, the network device can configure the secondary cell measurement cycle (measCycleSCell) parameter, causing the terminal to perform T... fast The subsequent relaxation measurement or cessation of measurement.

[0112] In some implementations, in T fast Subsequently, after an OD SSB activation or deactivation time window, the terminal can perform SCell measurements based on the conventional or legacy SCell deactivation measurement method, which refers to measuring according to the measCycleSCell configuration. For example, referring to Figure 1B, at T fastAfterwards, an activated OD SSB is available, but the terminal is not required to measure SCell based on the periodicity of the OD SSB. Instead, SCell measurement is performed according to the measCycleSCell configuration or general requirements.

[0113] It's worth noting that in the related discussions, `measCycleSCell` can only be used for SCells in a deactivated state. For example, see the following description of the `measCycleSCell` field: This parameter is only used when the SCell is configured on the frequency indicated by the `measObjectNR` field and is in a deactivated state. The gNB configures this parameter whenever a SCell is configured on the frequency indicated by `measObjectNR`, but the field also indicates this when the SCell is not configured. Possible values ​​for this parameter include: `sf160` corresponding to 160 sub-frames, `sf256` corresponding to 256 sub-frames, etc.

[0114] For example, the detection period (T) of the primary synchronization signal (PSS) or secondary synchronization signal (SSS) of the deactivation SCell in FR1 is... PSS / SSS_sync_intra As shown in Table 1-1:

[0115] Table 1-1

[0116] Where DRX stands for Discontinuous Reception, Ceil represents the round-up operation, and K... p Configurable via network, CSSF intra This indicates an additional scaling factor.

[0117] In some implementations, in T fast Afterwards, the SCell may be in an active state, such as when the SCell is in T. fast It is then activated, but at this point it does not meet the application conditions for measCycleSCell, meaning measCycleSCell is unavailable.

[0118] As shown in Figure 1C, the network device can simultaneously send SCell activation and OD SSB activation signals at time t1, or in other words, the terminal receives both signals at time t1 (sending and receiving are corresponding actions; the following embodiment describes sending as an example). The network device sends a SCell activation completed signal at time t2 and an OD SSB deactivation signal at time t3. After t1, T... fast In this process, the terminal can measure the OD SSB once per OD SSB cycle, where Tc1 represents the OD SSB cycle. In T... fast Afterwards and before t3, the terminal can revert to legacy measurement. After t3, the terminal can adopt legacy measurement. In legacy measurement, the measurement cycle may differ from Tc1. Referring to the scenario shown in Figure 1C, the SCell is in an activated state before receiving the deactivation signaling, such as in Tc1. fast During the subsequent time interval [t2, t3], the SCell is active, and if L3 reporting is configured during SCell activation, the terminal needs to measure the SCell during this period. However, since measCycleSCell is unavailable during SCell activation, the measurement of the SCell will not occur during T... fast It is still unclear how the terminal will measure the measurement.

[0119] In some implementations, the terminal needs to activate the SCell based on measurements from the OD SSB. For example, in the scenarios shown in Figures 1C to 1E, or in a SCell activation scenario with L3 reporting during SCell activation.

[0120] As shown in Figure 1D, in the time domain, the network device can sequentially send at least one of the following: SCell configuration signaling, SCell activation signaling, OD SSB triggering signaling, or SCell activation completion signaling. The OD SSB triggering signaling does not need to be sent separately; it is triggered by the terminal after receiving the SCell activation signaling. In this scenario, the OD SSB can be activated during the period from when the terminal receives the SCell activation signaling to when SCell activation is complete.

[0121] As shown in Figure 1E, in the time domain, the network device can sequentially send at least one of the following: SCell configuration signaling, SCell activation signaling, SCell activation completion signaling, or OD SSB triggering signaling. The OD SSB triggering signaling does not need to be sent separately; it is triggered by the terminal after receiving the SCell activation signaling. In this scenario, the OD SSB can be activated when the terminal receives the SCell activation signaling and SCell activation is complete, or it can be activated after SCell activation is complete.

[0122] Based on the above description, as shown in Figures 1C to 1D, the measurement requirements for deactivating SCells in conventional measurements are not applicable to all OD-SSB scenarios. fast Subsequent measurements. At T fast Subsequently, there was a lack of effective measurement methods for performing SCell measurements on the terminal.

[0123] Figure 2 is an interactive schematic diagram of a measurement method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method, which includes:

[0124] In step S2101, terminal 101 receives configuration information sent by network device 102.

[0125] In some embodiments, network device 102 sends configuration information to terminal 101.

[0126] In some embodiments, the configuration information is used to configure the secondary cell measurement cycle measCycleSCell.

[0127] Optionally, measCycleSCell is used for the SCell that is active after the measurement window.

[0128] Optionally, the SCell that is active after the measurement window can be a SCell that is active after being activated using OD SSB.

[0129] Optionally, the applicable conditions or Radio Resource Management (RRM) measurement requirements in this configuration information may include: when the SCell is configured on the frequency indicated by the measObjectNR field and is in a deactivated state; or when the SCell is configured on the frequency indicated by the measObjectNR field and is in an active state after the measurement window (or is in an active state after the SCell is activated using OD-SSB after the measurement window). The gNB configures this parameter whenever a SCell is configured on the frequency indicated by measObjectNR, but the field also indicates this when the SCell is not configured. Possible values ​​for this parameter include: sf160 corresponding to 160 subframes, sf256 corresponding to 256 subframes, etc.

[0130] It is worth emphasizing that measCycleSCell can reuse existing fields, but the applicable conditions or definition methods of measCycleSCell differ from those of existing fields. Alternatively, in some embodiments, new fields can be configured to apply to measCycleSCells that are active SCells after the measurement window.

[0131] In some embodiments, the measurement window may be as described in step S2103.

[0132] In step S2102, network device 102 sends OD SSB to terminal 101.

[0133] In some embodiments, network device 102 sends OD SSB to terminal 101 on SCell, and terminal 101 receives OD SSB on SCell, or in other words, receives SCell OD SSB.

[0134] In some embodiments, the OD SSB is used for at least one of the following: SCell time-frequency synchronization, L1 or L3 measurement, and SCell activation. This disclosure describes embodiments using the OD SSB for SCell activation as an example.

[0135] In some embodiments, OD SSB refers to an adaptive SSB method in which network devices can reduce the number of SSBs sent based on demand. For example, the network device triggers the transmission of OD SSB based on trigger signaling, and the terminal receives OD SSB based on trigger signaling; or, the terminal sends a request to the network device when it needs an SSB, and the network device sends an OD SSB based on the request. Compared with conventional SSB, the above OD SSB methods can reduce the number of SSBs sent by the network device, thereby achieving network energy saving.

[0136] In some embodiments, in conjunction with the descriptions of Figures 1C to 1E, network device 102 can activate or trigger the transmission of OD SSB via signaling.

[0137] In some embodiments, in conjunction with the description of FIG1B or FIG1C, at least for a period of time (such as within the measurement window T described below) fast Within (the specified range), network device 102 can send OD SSB according to the OD SSB cycle or transmission cycle. In the measurement window T fast Subsequently, the period during which network device 102 sends OD SSB can be longer than the period within the measurement window.

[0138] In step S2103, terminal 101 determines the first measurement cycle after the measurement window based on the first parameter.

[0139] In some embodiments, the transmission period of the OD SSB in the measurement window is less than a preset value.

[0140] Optionally, the preset value can represent a constant.

[0141] Optionally, the default values ​​can be defined by the protocol or configured by the network device.

[0142] Optionally, the transmission period of OD SSB is less than a preset value, indicating that the period of OD SSB is as short as possible within the measurement window, and OD SSB is more frequent.

[0143] Alternatively, referring to Figure 1B, the measurement window can refer to the fast measurement window T. f or T fast Within this measurement window, terminal 101 can receive and measure OD SSB based on the period or transmission period of OD SSB; for example, within the measurement window, the measurement period of OD SSB by terminal 101 is equal to the period or transmission period of OD SSB.

[0144] Optionally, the measurement period of OD SSB in the measurement window is less than a preset value.

[0145] In some embodiments, within a measurement window, terminal 101 can receive and measure OD SSB according to the transmission cycle of OD SSB, such that the actual measurement cycle of OD SSB is the same as the transmission cycle within the measurement window.

[0146] In some embodiments, for measurements after the measurement window, such as T in Figure 1B or Figure 1C s or T slow For the measurement, terminal 101 needs to determine the first measurement period based on the first parameter. Outside the measurement window, the actual measurement period of the OD SSB may differ from the transmission period.

[0147] Optionally, the first measurement period indicates the applicable T fast The actual measurement period measured in subsequent time periods or windows, for example, applicable to T. slow The actual measurement cycle of the measurement.

[0148] In some embodiments, the first parameter is determined by the terminal 101 based on the parameters configured by the network device 102.

[0149] In the first example, the first parameter is determined based on the measCycleSCell configured in network device 102 in step S2101. This example applies to scenarios where network device 102 is configured with measCycleSCell, such as the scenario executed in step S2101. For example, the first parameter is the same as measCycleSCell, or it is determined based on a calculation of measCycleSCell and other parameters.

[0150] In an optional example of this example, the first parameter includes measCycleSCell, as if the first parameter were the same as measCycleSCell.

[0151] In this alternative example, terminal 101 can determine the first measurement period based on measCycleSCell. For example, the first measurement period is the same as the period value of measCycleSCell, or the first measurement period is determined based on the calculation of measCycleSCell with other parameters or constants.

[0152] In the second example, the first parameter can be at least one of the following: the measurement period of the OD SSB, and a preset period value.

[0153] In this example, the measurement period of OD SSB can be configured by network device 102. Alternatively, the measurement period of OD SSB can be denoted as T. c2 Alternatively, it can be denoted as Tc_odssb. Optionally, network device 102 can configure the measurement period of the OD SSB using the above configuration information, or configure the measurement period of the OD SSB using separate signaling.

[0154] In this example, the preset period value can represent a fixed period value, which can be predefined by the protocol or configured by the network. For example, optionally, the preset period value is 160 milliseconds (ms).

[0155] In this example, terminal 101 can determine the first measurement cycle based on the measurement cycle of OD SSB and / or a preset cycle value.

[0156] Optionally, the first measurement period is the maximum value between the measurement period of the OD SSB and a preset period value. For example, the first measurement period is determined based on the following formula: max(T c2 [160ms]

[0157] This example can be applied to scenarios where network device 102 is not configured with measCycleSCell, such as when step S2101 is not executed.

[0158] In step S2104, after the measurement window, terminal 101 receives OD SSB according to the first measurement cycle.

[0159] In some embodiments, after the measurement window, terminal 101 receives OD SSB sent by network device 102 on SCell according to a first measurement cycle.

[0160] In step S2105, terminal 101 measures the OD SSB after the measurement window.

[0161] In some embodiments, terminal 101 can measure the window after T, such as... slow The SCell OD SSB inside is used for measurement.

[0162] In some embodiments, after the measurement window, the SCell can be either active or deactivated.

[0163] Optionally, the SCell in an active state can be activated based on OD SSB after the measurement window.

[0164] In step S2106, terminal 101 determines the second measurement cycle based on the first measurement cycle.

[0165] In some embodiments, the second measurement period is the period from when the terminal sends the measurement window to the network device, after which the measurement results are received.

[0166] For example, after the measurement window, such as in T slow Within the first measurement cycle, terminal 101 performs measurements and reports the measurement results to the network device according to the second measurement cycle.

[0167] In some embodiments, the second measurement period can be determined based on the first measurement period, such as by determining the second measurement period based on the first measurement period and the number of measurements.

[0168] Optionally, the terminal 101 may report a measurement result once during each second measurement cycle. A single measurement result can be determined based on multiple measurements within the second measurement cycle, where each measurement in the multiple measurements may refer to a measurement within a first measurement cycle.

[0169] In some embodiments, for intra-frequency measurements without a measurement gap, the second measurement period (TSB_measurement_period_intra) can be determined as shown in Tables 2-1 to 2-4:

[0170] Table 2-1 Measurement period (deactivation SCell) for same-frequency measurements without measurement intervals (FR1)

[0171] The meanings of the parameters in Table 2-1 can be found in the description of the embodiment in Table 1-1.

[0178] In step S2107, terminal 101 sends the measurement result to network device 102 according to the second measurement cycle.

[0179] In some embodiments, terminal 101 performs multiple measurements based on a first measurement cycle, and can report the measurement results determined based on the multiple measurements according to a second measurement cycle.
