Description

SSB measurement methods, configuration methods and devices Technical Field

[0001] This application relates to the field of communications. Background Technology

[0002] In 5G's NR NTN (Non-Terrestrial Network) technology, terminal devices can access wireless networks by directly connecting to satellites. The coverage of the wireless network provided by satellites is related to the satellite's altitude; the higher the satellite's altitude, the larger the area of ​​the Earth it can cover.

[0003] Figure 1 is a schematic diagram of the Earth's surface coverage by satellites at a certain altitude. Taking Figure 1 as an example, as shown in Figure 1, for a Low Earth Orbit (LEO) satellite at an altitude of 600 km, assuming a minimum elevation angle of 30° for the terminal equipment, the coverage area can reach 2,285,851 km². 2 If the minimum allowable elevation angle for terminal devices is reduced to 10°, the Earth's surface that a satellite could cover would be significantly larger. For such a vast coverage area, to ensure that terminal devices at different locations receive signals from the satellite with a 5MHz bandwidth, the satellite's total transmission power would need to exceed 10 kilowatts. This would be extremely difficult to achieve for satellites powered by solar energy. For satellites in higher orbits, the covered area would likely be even larger, requiring even higher total transmission power. This would also be very difficult for satellites powered by solar panels.

[0004] In the 3GPP Release 19 NR NTN work proposal on downlink coverage enhancements (DL-CE) technology, the above-mentioned power issue is considered to be addressed by not activating all the satellite beams at the same time.

[0005] Figure 2 is a schematic diagram of the coverage area of ​​a satellite cell. As shown in Figure 2, during a specific time period, the satellite's transmit power is concentrated on ensuring signal transmission on a portion of the satellite beams. This means the satellite can only provide NTN downlink service to the areas corresponding to these satellite beams. After the specific time period ends, the satellite's power may be concentrated on signal transmission on other beams, and so on. By employing a time-division multiplexing approach, the satellite can dynamically and flexibly allocate its total power across different beams to provide NTN downlink service to the entire area within its satellite footprint. This also means that for a specific area or location within the satellite, the NTN network coverage provided by that satellite is discontinuous in time. Only when the satellite activates the beam corresponding to that area with sufficient power can the NTN network providing coverage from that satellite send downlink signals or transmissions to the UEs in that area. Sending downlink signals or transmissions also includes sending the Synchronization Signal / PBCH Block (SSB) of the NR cell.

[0006] Considering that satellites use a time-division multiplexing approach to provide coverage for areas corresponding to thousands of beams within their entire satellite footprint, the period for a satellite to activate a specific beam to transmit SSBs may exceed 20ms. In 3GPP protocol versions prior to Rel-19, the UE (User Equipment) defaults to detecting SSBs at a 20ms interval to search for cells, which can result in situations where no cell is found within 20ms. In other words, the NR NTN downlink coverage enhancement technology in Rel-19 may not be compatible with UEs from versions prior to Rel-19.

[0007] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0008] Currently, for all SSB-based measurements, there can be at most one measurement object per SSB frequency; the parameter values ​​of the SS / PBCH block measurement timing configuration (SMTC) are identical for all measurement objects with the same SSB frequency. Therefore, a terminal device uses the same SMTC-related configurations for different cells with the same SSB frequency, including the primary measurement timing configuration smtc1, a secondary measurement timing configuration smtc2 which can provide a shorter period than the primary measurement timing configuration, the long-period configuration SSB-MTC3List for measuring the SSB of neighboring cells at the same frequency, and the SSB-MTC4List which can be configured with additional offsets.

[0009] For cells operating at the same frequency, the terminal equipment measures the SS / PBCH blocks of these cells, with the measurement period determined by the relevant SMTC configuration. SS / PBCH blocks can also be abbreviated as SSBs. Since the SMTC configuration is identical for the same SSB frequency, SSB measurements for cells operating at the same frequency can only apply the period configuration of the primary measurement timing, or the short period indicated by the secondary measurement timing configuration, or the long period timing configuration; the measurement timing configuration period cannot be configured separately for each cell. When measuring the SSB of cells operating at the same frequency, the offset of the measurement timing configuration can either be applied using the primary measurement timing configuration, or a fixed additional offset can be used; different offsets cannot be configured for different cells.

[0010] When applying NR NTN DL-CE, the downlink signals, including SSBs, that network devices can transmit in a given area may be discontinuous. If a terminal device assumes that half-frames containing SSBs occur at 20ms intervals, and the period for activation of the beam covering that area exceeds 20ms, and the deactivation time also exceeds 20ms, the terminal device may not be able to detect any SSB transmission within the expected 20ms, thus affecting the access of terminal devices in that area and subsequent downlink information reception. The period during which network devices provide SSBs in that area is limited by the period for activation of the beam covering that area and the duration of deactivation within that period.

[0011] Based on current RAN discussions, in implementing NR NTN downlink enhancement technologies, terminal devices assume that the maximum period of occurrence of half-frames containing SSBs has been extended from 20ms to 160ms. This means the period during which the terminal device can measure SSBs may be extended to a maximum of 160ms. However, due to different satellite power sharing patterns, the period during which network devices can transmit SSBs may vary depending on the satellite beam. For satellite beams with high activation frequencies and long activation durations, network devices can transmit SSBs with shorter periods. For beams with low activation frequencies, network devices may have to use longer periods, or even the maximum period of 160ms, to transmit SSBs. Therefore, when terminal devices measure SSBs for different beams, the applied SS / PBCH block measurement timing configuration (SMTC) may use a shorter period or may have to use a larger period, such as 160ms.

[0012] In the existing technology, for all cells to be measured with the same SSB frequency, the SMTC that the terminal device can obtain is the same. That is, by configuring the main measurement timing configuration, a measurement period of SSB, the corresponding offset, and the duration can be obtained. By configuring the second measurement timing configuration smtc2, an additional period with a shorter period than the period in the main measurement timing configuration can be obtained. Alternatively, a period with a longer period than the period in the main measurement timing configuration can be obtained through SSB-MTC3List, or an additional offset different from the main measurement timing configuration can be obtained through SSB-MTC4List.

[0013] In an NTN network, the terminal equipment may need to measure far more than four cells employing Downlink Coverage Enhancements (DL-CE) technology. The beam activation patterns for these DL-CE cells may differ, for example, employing different activation periods and different offsets within those periods. In existing technologies, these cells can be configured with a maximum of three SMTC periods, with the same offset within each period, or a maximum of two initial offsets within each SMTC period, with the two different offsets corresponding to the same period. This is insufficient to address the situation where different cells may use different periods and offsets within each period to transmit SSBs after the introduction of DL-CE technology.

[0014] In addition, there is currently no beam-based SMTC configuration. If beams within the same cell are not activated with the same period and offset, different beam configurations may require different SMTCs, which is not supported by existing technology.

[0015] To address one or more of the aforementioned problems, embodiments of this application provide a method, configuration method, and apparatus for measuring SSB.

As shown in Figure 3, the communication system 100 may include a network device 101 and a terminal device 102. For simplicity, Figure 3 only uses one terminal device and one network device as an example for illustration, but the embodiments of this application are not limited thereto.

[0059] In this embodiment of the application, network device 101 and terminal device 102 can transmit existing services or services that can be implemented in the future. For example, these services may include, but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0060] In the embodiments of this application, higher-layer signaling may be, for example, Radio Resource Control (RRC) signaling; for example, referred to as an RRC message, including MIB, system information, dedicated RRC messages; or referred to as an RRC information element. Higher-layer signaling may also be, for example, Medium Access Control (MAC) signaling; or referred to as a MAC control element. However, this application is not limited to these.

[0061] In Rel-19, NR NTN downlink enhancement technology refers to the use of satellite power sharing. This involves dynamically allocating the total transmit power of a satellite to different beams and / or beam patterns and / or beam sizes. By obtaining a satellite beam with sufficient power, network devices can send downlink signals or downlink transmissions to terminal devices within the coverage area of ​​that beam. When these downlink signals or transmissions reach the terminal devices, they have sufficient signal strength to be detected or resolved by the terminal devices. For satellite beams without sufficient power, they cannot be used to send signals with sufficient strength to be detected or resolved by the terminal devices.

[0062] The satellite power sharing mechanism or beam hopping mechanism of NR NTN downlink enhancement technology makes the downlink transmission of satellite cells or cell beams discontinuous in time. In other words, in NR NTN downlink enhancement technology based on satellite power sharing, the period and start position of the SSB transmitted by network equipment through satellite beams need to match the power sharing pattern between satellite beams. Different satellite beams are activated at different periods and at different start times within the period. These satellite beams can also transmit half-frames including SSBs at different periods and at different start positions within the period.

[0063] In TN, downlink transmission is unrestricted, and network devices typically send SSBs at a period of no more than 20ms. When a terminal device initially accesses the network, it assumes that the period of a half frame, which includes the SSB, is 20ms.

[0064] In downlink enhanced CE (DL-CE) NTN networks, due to power sharing, the activation time and period of different beams may be different. Therefore, the transmission of SSBs through these beams may also be limited. For example, if some beams in a cell are synchronously activated with a period of 80ms and the duration of activation is less than 20ms, then the minimum period for transmitting SSBs in that cell is 80ms. For example, at the time positions of 20ms, 40ms, and 60ms after the start of an SSB transmission, since none of the beams in the cell have been activated, SSBs cannot be transmitted.

[0065] In a downlink enhanced CE (DL-CE) NTN network, for example, if beams 1-4 within a cell are synchronously activated with a period of 80ms and beams 5-8 are synchronously activated with a period of 40ms, then the minimum period for beams 1-4 to transmit SSBs is 80ms, and the minimum period for beams 5-8 to transmit SSBs is 40ms. Therefore, at time points 20ms and 60ms after a cell starts transmitting SSBs through beams 1-8, all beams within the cell cannot transmit SSBs; at time point 40ms, only beams 5-8 can transmit SSBs, while beams 1-4 cannot transmit SSBs.

[0066] In this embodiment of the application, cells in both the NTN network and the TN network may be candidate cells for the terminal device to measure the SSB.

[0067] Figure 4 is a schematic diagram of candidate cells to be measured by the terminal device according to an embodiment of this application. As shown in Figure 4, the candidate cells to be measured by the terminal device include cells within the satellite footprint, namely satellite cells (NTN cells), including cell 1 and cell 3; in addition, the candidate cells to be measured by the terminal device also include TN cells, namely cell 2.

[0068] In cell 1, beams 1 and 2 are activated and deactivated simultaneously, as are beams 3 and 4. Beams 1 and 3 are not activated simultaneously. The activation periods and / or time-domain positions of beams 1 and 3 are different, and the duration of each activation may also differ. Therefore, the period and duration for SSB transmission on beams 1 and 3 are also different. When a terminal device wants to measure SSBs in the cell, the same SMTC (Segmented Mode and Time Coefficient) can be applied when measuring SSBs transmitted on beams 1 and 2, such as period, offset, and duration. However, when measuring SSBs transmitted on beams 3 and 4, a different SMTC is required.

[0069] Figure 5 is a timing diagram for measuring SSBs transmitted on different beams in a cell according to an embodiment of this application. As shown in Figure 5, for the cell 1 described above, the same SMTC can be applied when measuring SSBs transmitted on beams 1 and 2, namely period 2, offset 2, and duration 2; while when measuring SSBs transmitted on beams 3 and 4, the same other SMTC is applied, namely period 1, offset 1, and duration 1.

[0070] In cell 3, all beams use a synchronous activation mechanism, so all beams can apply the same SMTC period, offset, and duration.

[0071] Figure 6 is another timing diagram for measuring SSBs transmitted on different beams in a cell according to an embodiment of this application. As shown in Figure 6, for the cell 3 described above, the same SMTC can be applied when measuring SSBs transmitted on beams 1-4, i.e., the same period 3, offset 3, and duration 3.

[0072] Cell 2 is a TN cell. For Cell 2, network devices are not limited by beam activation issues when sending SSBs and can continuously send them at 20ms intervals. Measuring the SMTC configuration corresponding to the SSB of Cell 2 only requires considering the performance of the terminal devices. For example, when generally measuring the performance of a supervised cell, the terminal device uses a longer SMTC period to reduce measurement overhead. During handover preparation, the terminal device uses a shorter SMTC period to quickly obtain the performance of the candidate cell.

[0073] Therefore, when the terminal device measures the SSB on cell 1, cell 2, and cell 3, it may be necessary to apply different SMTCs.

[0074] Various embodiments of the present application will now be described with reference to the accompanying drawings. These embodiments are merely exemplary and are not intended to limit the scope of the present application.

[0075] First aspect of the embodiments

[0076] This application provides a method for measuring SSB, which is applied to a terminal device, such as terminal device 102 in FIG3.

[0077] Figure 7 is a schematic diagram of an SSB measurement method according to an embodiment of this application. As shown in Figure 7, the method includes:

[0078] 701: The terminal device receives first information from the network device, the first information being used at least to configure the SSB measurement timing configuration (SMTC) of the first measurement object;

[0079] 702: The terminal device measures the SSB transmitted on the first measurement object according to the SMTC used for the first measurement object.

[0080] In this embodiment of the application, the first measurement object includes beam-related measurement objects and / or cell-related measurement objects.

[0081] In the embodiments of this application, SSB refers to SS / PBCH block, that is, SS / PBCH block can be simply referred to as SSB.

[0082] In the embodiments of this application, the SS / PBCH block measurement timing configuration can also be referred to as the SSB measurement timing configuration. In addition, the SS / PBCH block measurement timing configuration or the SSB measurement timing configuration can be simply referred to as SMTC.

[0083] In the embodiments of this application, the SMTC configured by the network device for the first measurement object can also be referred to as the SMTC at the first measurement object level, that is, the SMTC configured by the network device is a beam-level and / or cell-level SMTC.

[0084] In this way, the terminal device measures the SSBs transmitted on the beam and / or cell according to the SMTC configuration of the network device for beam-related measurement objects and / or cell-related measurement objects. Therefore, when the beams of cells and / or cells are activated in different patterns, the terminal device can measure the SSBs transmitted on different cells or cell beams separately, ensuring the reliability of downlink transmission in NTN or TN.

[0085] In this embodiment of the application, the first information received by the terminal device from the network device is used at least to configure the SMTC of the first measurement object, and the configuration of the SMTC of the first measurement object includes at least one of the following:

[0086] The first cycle is the measurement cycle for measuring the SSB transmitted on the first measurement object;

[0087] A first offset, which is used to indicate the measurement start position of the SSB transmitted on the first measurement object within the first cycle;

[0088] The first duration is the measurement duration of the SSB transmitted on the first measurement object within the first cycle.

[0089] In this embodiment of the application, the first information may further include relevant information about the first measurement object, which is used to indicate the first measurement object to which the SMTC configuration is applied, for example, indicating at least one of the beam, beam group, cell, and cell group to which the SMTC is applied.

[0090] The first measurement object configured by the SMTC in the application network device configuration includes beam-related measurement objects and / or cell-related measurement objects. For example, the beam-related measurement object includes a first beam and / or a first beam group; the cell-related measurement object includes a first cell and / or a first cell group.

[0091] The following sections provide specific explanations for different scenarios regarding the first measurement object (beam-related measurement object and / or cell-related measurement object) configured for this SMTC on the application network equipment.

[0092] In this embodiment of the application, when the beam-related measurement object includes a first beam, the configuration of the SMTC for the first beam includes at least one of the following:

[0093] The first relevant information of the first beam; for example, the first relevant information of the first beam includes at least one of the identifier, index and pointer of the first beam;

[0094] The second cycle is the measurement cycle for measuring the SSB transmitted on the first beam;

[0095] The second offset is used to indicate the measurement start position of the SSB transmitted on the first beam within the second period.

[0096] The second duration is the measurement duration of the SSB transmitted on the first beam within the second period.

[0097] In this embodiment of the application, for the case where the beam-related measurement object includes a first beam group and the first beam group includes multiple second beams, in this case, all the second beams in the first beam group are synchronously activated beams, and the SMTC configuration for the first beam group is the SMTC configuration common to all the second beams in the first beam group.

[0098] In this case, the configuration of the SMTC for the first beam group includes at least one of the following:

[0099] The second relevant information of the first beam group; for example, the second relevant information of the first beam group includes relevant information of all second beams belonging to the first beam group, and the relevant information of the second beam includes at least one of the identifier, index and pointer of the second beam;

[0100] The third period is the measurement period for measuring the SSBs transmitted on all the second beams in the first beam group;

[0101] The third offset is used to indicate the measurement start position of the SSBs transmitted on all the second beams in the first beam group within one of the third cycles.
