Description

SSB measurement method, SSB measurement indication method and device 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 airborne objects such as satellites. However, since satellites cover a much larger area than terrestrial network equipment (such as base stations), the total power of the satellites cannot support the simultaneous activation of all beams within their coverage area. Alternatively, the radiation energy of each satellite beam may be too small to meet the downlink signal transmission requirements in different directions within the satellite's coverage area.

[0003] In the 3GPP Release 19 NR NTN work proposal on downlink coverage enhancement, the above power problem is addressed by considering a method that does not activate all satellite beams simultaneously.

[0004] Figure 1 is a schematic diagram of the coverage area of ​​a satellite cell. As shown in Figure 1, during a specific 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 this specific period ends, the satellite's power may be concentrated on signal transmission on other beams, and so on. Using 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 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 terminal equipment (UE) in that area. Sending downlink signals or transmissions also includes sending the SS / PBCH block (SSB) of the NR cell.

[0005] Prior to Rel-19, 3GPP protocol versions used a default 20ms period for SSB detection to search for cells and initiate initial access. Considering that NTN downlink enhancement technology employs time-division multiplexing to provide coverage for different areas, 3GPP decided to extend the period of the half-frame carrying SSBs to a maximum of 160ms. This means that in cells using NTN downlink enhancement technology, terminal devices should receive SSBs at a 160ms period instead of the 20ms period during initial access. Therefore, the relevant 3GPP specifications need to be enhanced to support NTN downlink enhancement technology. In cells using this technology, terminal devices that do not support Rel-19 NR NTN downlink enhancement technology may experience limited or no operation.

[0006] 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

[0007] In existing technologies, for all SSB-based measurements, there is 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 for different cells with the same SSB frequency.

[0008] For terminal devices accessing via NR NTN networks, the SMTC configuration for measuring SSB applications typically includes a basic SMTC configuration, such as smtc or smtc1, and up to three SMTC configurations with additional offsets, such as smtc4list.

[0009] The basic SMTC configuration is of type SSB-MTC, including a period and offset / duration of the measurement window in which to receive SS / PBCH blocks, such as smtc and smtc1, as shown below:

[0010] The SMTC configuration for this additional offset is of type SSB-MTC4, which indicates the additional offset (offset of the measurement window in which to receive SS / PBCH blocks) in addition to the offset in the base SMTC, as well as a list of physical cell identifiers (PCIs that follow this SMTC) that follow this additional offset configuration, such as smtc4list, as shown below:

[0011] The SMTC configuration used to configure additional offsets does not include a period configuration. When measuring SSB in accordance with the additional SMTC configuration, the terminal device applies the period and duration indicated in the basic SMTC configuration.

[0012] The existing protocol also includes a configuration for an additional periodic SMTC, indicating an additional period beyond the period in the basic SMTC, and a list of physical cell identifiers (e.g., SMTC2 or SMTC2-LP) that follow each period of this configuration. The type of this SMTC configuration for the additional period is SSB-MTC2 or SSB-MTC2-LP. When measuring SSBs according to this additional periodic SMTC configuration, the terminal device applies the offset and duration indicated in the basic SMTC configuration. As shown below:

[0013] In current NR NTN technology, for co-frequency cells, terminal equipment can only apply the same measurement period and a maximum of four offsets within that period when measuring SSBs. However, in NR NTN downlink coverage enhancement technology, if some co-frequency cells have a half-frame containing SSBs with a period of 20ms, while others have a half-frame containing SSBs with a period of 160ms, the offsets for transmitting SSBs will differ depending on the activation time of the corresponding satellite beams within each period. Existing technology cannot meet the requirement of configuring different offsets for different periods.

[0014] Based on the current progress of RAN discussions, in implementing NR NTN downlink enhancement technology, terminal equipment assumes that the possible value of the occurrence period of a half-frame containing SSBs has increased by 160ms in addition to the existing 20ms. In other words, the period during which the terminal equipment can measure SSBs could be either 20ms or 160ms.

[0015] In existing NR NTN technology, for all cells under measurement with the same SSB frequency, the SMTC configuration followed by the terminal equipment includes only one SSB measurement period and a maximum of four offsets within that period. The terminal equipment cannot measure the SSB of one group of cells with a 20ms period and the SSB of another group of cells with a 160ms period. For example, existing NR NTN technology does not support the terminal equipment using a 20ms period SMTC configuration to measure the SSB of one group of cells while simultaneously using a 160ms period SMTC configuration to measure the SSB of another group of cells.

[0016] Even though NR NTN technology allows terminal devices to apply additional periods to measure the SSB of the second group of cells based on the SMTC configuration with additional periods, the existing technology cannot meet the requirements of DL-CE technology in Rel-19 when the positions of the half-frames containing SSBs in each cell of the second group of cells are different, or even different from the positions of the half-frames containing SSBs in each cell of the first group of cells. For example, the period of the basic SMTC configuration is 20ms, the offset is 3, the offsets of the three additional SMTC configurations with additional offsets are {6, 9, 12}, and the period of the SMTC configuration with additional periods is 160ms. However, the SMTC configuration with additional periods can only apply the offset of 3, and cannot indicate other positions within the 160ms period; the offset of the SMTC configuration with additional offsets can only be the position within the 20ms period of the basic SMTC configuration, and cannot indicate the offset within the 160ms period outside of 20ms.

[0017] To address one or more of the aforementioned problems, embodiments of this application provide a method for measuring SSB, an indication method for SSB measurement, and an apparatus.

[0018] According to one aspect of the embodiments of this application, a measurement device for an SSB is provided. The device is applied to a terminal device and includes: a processing unit that determines a first measurement window based on a first period and a first offset, and determines a second measurement window based on a second period and a second offset; and a receiving unit that receives and / or measures a first SSB (SS / PBCH block) in the first measurement window, and receives and / or measures a second SSB in the second measurement window.

[0019] According to another aspect of the embodiments of this application, an indication device for SSB measurement is provided.

The first period is used to indicate the period during which the terminal device receives and / or measures a first SSB, and the second period is used to indicate the period during which the terminal device receives and / or measures a second SSB.

[0020] According to another aspect of the embodiments of this application, a communication system is provided, the communication system including a terminal device and / or a network device, the terminal device including the above-described SSB measurement device according to the embodiments of this application, and the network device including the above-described SSB measurement indication device according to the embodiments of this application.

[0021] According to another aspect of the embodiments of this application, a method for measuring an SSB is provided, the method being applied to a terminal device, the method comprising: the terminal device determining a first measurement window based on a first period and a first offset, and determining a second measurement window based on a second period and a second offset; the terminal device receiving and / or measuring a first SSB (SS / PBCH block) in the first measurement window, and receiving and / or measuring a second SSB in the second measurement window.

[0022] According to another aspect of the embodiments of this application, a method for indicating SSB measurement is provided. The method is applied to a network device, and the method includes: the network device sending first information to a terminal device, the first information including at least a first period and / or a second period, the first period being used to indicate the period during which the terminal device receives and / or measures a first SSB, and the second period being used to indicate the period during which the terminal device receives and / or measures a second SSB.

[0027] One of the beneficial effects of the embodiments of this application is that:

[0028] When nearby cells may be using NR NTN downlink enhancement technology, the terminal device can use two different cycles, namely the first cycle and the second cycle, to receive and / or measure SSBs in multiple measurement windows with different offsets. Therefore, when the activation interval of the satellite beam is long, the corresponding cell can not only measure cells that transmit SSBs according to the second cycle (e.g., 160ms) as a long cycle, but also cells that transmit SSBs according to the first cycle (e.g., 20ms) as a short cycle. This avoids the power consumption of the terminal device and the problem of filtering smoothing caused by over-measurement, while also taking into account the measurement efficiency of measuring cells that transmit SSBs according to the short cycle.

[0029] In addition, the terminal device can also perform initial access based on the characteristics of the received SSB signal.

[0059] 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.

[0060] 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. The periods and start positions of the half frames including SSBs that these satellite beams can transmit are also different.

[0061] 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 the half frame, which includes the SSB, is 20ms.

[0062] In the downlink enhancement technology of NR NTN using Rel-19, since satellite power is dynamically shared among different satellite beams, there is a need for some beams to be activated at least once within 20ms. Therefore, in addition to 20ms, 3GPP is considering introducing 160ms as an additional default period for terminal equipment to receive SSB. That is, in NR NTN networks using DL-CE, network equipment may send SSB with a period of 160ms.

[0063] The cell in which the terminal device is measuring the SSB could be a TN network cell or an NR NTN network cell. NR NTN network cells may use Rel-19 NR NTN downlink enhancement technology and transmit SSBs at 160ms intervals. Therefore, the terminal device's reception interval may differ for different SSBs.

[0064] For example, for an SSB transmitted with a period of 160ms, the terminal device receives and measures the SSB with a period of not less than 160ms. For an SSB with a transmission period of less than 160ms (e.g., 20ms or less), the terminal device can receive the SSB with a shorter period than 160ms and perform more frequent SSB measurements, thereby shortening the duration of handover processes and avoiding problems such as wireless link failure or handover failure.

[0065] 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.

[0066] First aspect of the embodiments

[0067] This application provides a method for measuring SSB, which is applied to a terminal device, such as terminal device 102 in FIG2.

[0068] Figure 3 is a schematic diagram of an SSB measurement method according to an embodiment of this application. As shown in Figure 3, the method includes:

[0069] 301: The terminal device determines a first measurement window based on a first cycle and a first offset, and determines a second measurement window based on a second cycle and a second offset;

[0070] 302: The terminal device receives and / or measures the first SSB in the first measurement window, and receives and / or measures the second SSB in the second measurement window.

[0071] In this way, when there may be surrounding cells using NR NTN downlink enhancement technology, the terminal device can use two different cycles, namely the first cycle and the second cycle, to receive and / or measure SSBs in multiple measurement windows with different offsets. Therefore, when the activation interval of the satellite beam is long, the corresponding cell can not only measure cells that transmit SSBs according to the second cycle (e.g., 160ms) as the long cycle, but also cells that transmit SSBs according to the first cycle (e.g., 20ms) as the short cycle. This avoids the power consumption of the terminal device and the problem of filtering smoothing caused by over-measurement, while also taking into account the measurement efficiency of measuring cells that transmit SSBs according to the short cycle.

[0072] In the embodiments of this application, SSB refers to SS / PBCH block, that is, SS / PBCH block can be simply referred to as SSB.

[0073] In operation 301, the terminal device determines a first measurement window based on a first cycle and a first offset, and determines a second measurement window based on a second cycle and a second offset.

[0074] For example, the terminal device determines a first measurement window based on a first period, a first offset, and a first duration, and determines a second measurement window based on a second period, a second offset, and a second duration.

[0075] In the embodiments of this application, the first duration is the length of a first measurement window of the first SSB within the first period, or the measurement duration of the first SSB starting from a first offset. The second duration is the length of a second measurement window of the second SSB within the second period, or the measurement duration of the second SSB starting from a second offset.

[0076] In this embodiment of the application, the first period is the measurement period for measuring the first SSB; the first offset is used to indicate the measurement start position of the first SSB within the first period; the value range of the first offset is determined by the length T1 of the first period, for example, 0 to T1-1;

[0077] In this embodiment of the application, the second period is the measurement period for measuring the second SSB; the second offset is used to indicate the measurement start position of the second SSB within the second period; the value range of the first offset is determined by the length T2 of the first period, for example, 0 to T2-1;

[0078] In this embodiment of the application, the first period is the period of the first measurement window, and the first offset is the offset of the first measurement window.

[0079] In this embodiment of the application, the second period is the period of the second measurement window, and the second offset is the offset of the second measurement window.

[0080] In this embodiment, the second period is a longer period than the first period. For example, the first period is 20ms and the second period is 160ms. However, other values ​​may also be used for the first and second periods in this embodiment.

[0081] In the embodiments of this application, the unit of period is milliseconds (ms), which can also be replaced by the number of subframes, or represented by the number of frames. For example, the first period is 20ms or 20 subframes or 2 frames, and the second period is 160ms or 160 subframes or 16 frames.

[0082] In the embodiments of this application, the first SSB is an SSB associated with the first period and / or the first offset, and the terminal device receives and / or measures the first SSB according to the first period and / or the first offset.

[0083] In the embodiments of this application, the second SSB is an SSB associated with the second period and / or the second offset, and the terminal device receives and / or measures the second SSB according to the second period and / or the second offset.

[0084] In this embodiment of the application, the first SSB and the second SSB are SSBs sent at different periods;

[0085] In the embodiments of this application, the first SSB and the second SSB are SSBs received by the terminal device according to different cycles.

[0086] In this embodiment of the application, at least one of the first cycle and the second cycle is indicated by a network device.

[0087] In one implementation, both the first period and the second period are indicated by a network device. For example, the network device indicates the first period and the first period is less than 160 ms (e.g., 20 ms), and the network device indicates the second period and the second period is equal to 160 ms.

[0088] In another implementation, the first cycle is indicated by the network device, and the second cycle is determined by the terminal device, for example, the terminal device determines the second cycle according to the implementation.

[0089] For example, the first period is indicated by the network device and the first period is less than 160ms, and the second period is determined by the terminal device to be 160ms. That is, the network device indicates the first period and the first period is less than 160ms, and the terminal device determines the second period to be 160ms.

[0090] In another implementation, the second cycle is indicated by the network device, and the first cycle is determined by the terminal device, for example, the terminal device determines the second cycle according to the implementation.

[0091] For example, the second period is indicated by the network device and the second period is equal to 160ms, and the first period is determined by the terminal device to be 20ms. That is, the network device indicates the second period and the second period is equal to 160ms, and the terminal device determines the first period to be 20ms.

[0092] In this embodiment of the application, the first cycle and the second cycle can be indicated by a first information sent by the network device.

[0093] For example, prior to operation 301, the method may further include: the terminal device receiving first information indicated by the network device.

[0094] In this embodiment of the application, the first information includes at least one of the following:

[0095] This first cycle;

[0096] At least one of these first offsets;

[0097] The second cycle;

[0098] At least one of these second offsets;

[0099] At least one primary community;

[0100] At least one of the first SSBs;

[0101] At least one second cell;

[0102] At least one of the second SSBs;

[0103] At least one third community;

[0104] At least one third SSB.

[0105] In this embodiment of the application, the first cell is the cell that sends the first SSB; that is, the first SSB is the first SSB of the first cell, that is, the SSB transmitted on the first cell.

[0106] In this embodiment of the application, the second cell is the cell that sends the second SSB; that is, the second SSB is the second SSB of the second cell, i.e., the SSB transmitted on the second cell.

[0107] In the embodiments of this application, the first cell and / or the second cell may be a cell in a TN network or a cell in an NTN network.

[0108] As mentioned above, the first information may also include at least one third cell and / or at least one third SSB.

[0109] In the embodiments of this application, the third cell can also be referred to as a "long-cycle cell", and the third SSB can also be referred to as a "long-cycle SSB".

[0110] In the embodiments of this application, the third SSB is an SSB sent according to the third cycle, and / or the third SSB is an SSB received by the terminal device according to the third cycle.

[0111] In this embodiment of the application, the third cell is the cell that sends the third SSB; that is, the third SSB is the third SSB of the third cell, that is, the SSB transmitted on the third cell.

[0112] In this embodiment, the third period is a longer period than the first period, and / or the third period is the same length as the second period. For example, the third period is 160ms.

[0113] Alternatively, the third cycle and / or the third SSB may not be indicated by the first information. For example, the network device may indicate the third cycle and / or the third SSB by other information besides the first information.

[0114] In the embodiments of this application, the first cycle and / or at least one of the first cells and / or at least one of the first SSBs are indicated by the first SSB measurement timing configuration (SMTC);

[0115] In this embodiment of the application, the second cycle and / or at least one of the second cells and / or at least one of the second SSBs is indicated by the second SSB measurement timing configuration (SMTC);

[0118] In this embodiment of the application, the terminal device determines that the fifth SMTC is the fourth SMTC and / or the offset indicated by the fifth SMTC is the second offset based on the fact that at least one cell indicated by the fifth measurement timing configuration (SMTC) is the third cell and / or at least one SSB is the third SSB.

[0119] In this embodiment of the application, the terminal device determines that the sixth SMTC is the third SMTC and / or the offset indicated by the sixth SMTC is the first offset based on the fact that at least one cell indicated by the sixth measurement timing configuration (SMTC) is not the third cell and / or at least one SSB is not the third SSB.

[0120] 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.

[0121] In the embodiments of this application, at least one of the first SMTC, the second SMTC, the third SMTC, the fourth SMTC, the fifth SMTC, and the sixth SMTC is a first type SMTC or a second type SMTC.

[0122] For example, the first type of SMTC refers to newly introduced SMTCs; the second type of SMTC is an existing SMTC that has been reused or enhanced.

[0123] In this application embodiment, the second type of SMTC includes at least one of the following:

[0124] smtc1 in MeasObjectNR;

[0125] smtc2 in MeasObjectNR;

[0126] smtc in SIB2;

[0127] smtc2-LP in SIB2;

[0128] smtc in SIB4;

[0129] smtc2-LP in SIB4;

[0130] smtc in CellGroupConfig;

[0131] smtc in MeasIdleConfig.

[0132] In the embodiments of this application, the first SMTC and the second SMTC may be the same SMTC. For example, the same SMTC may indicate the first cycle and the second cycle.

[0133] In the embodiments of this application, the third SMTC and the fourth SMTC may be the same SMTC or belong to the same SMTC list. For example, the first offset and the second offset may be indicated in the same SMTC or in the same SMTC list.

[0134] In the case where the third SMTC and the fourth SMTC are the same SMTC, in one implementation, at least one of the first offsets and at least one of the second offsets are configured using different parameters within the same SMTC.

[0135] In another implementation where the third SMTC and the fourth SMTC are the same SMTC, at least one of the first offsets and at least one of the second offsets are configured using the same parameter in the same SMTC, and the terminal device determines the parameter value of the first offset and / or the parameter value of the second offset in the configuration of the same parameter.

[0136] For example, in the configuration of the same parameter, at least one parameter value within the first period range is determined as at least one of the first offsets, and at least one other parameter value in the configuration of the same parameter is determined as at least one of the second offsets; or,

[0137] In the configuration of the same parameter, the first half of the parameter value is determined to be at least one of the first offsets, and the second half of the parameter value is determined to be at least one of the second offsets; or,

[0138] Based on the number (e.g., denoted as N-offset) and / or the order of the first offset and / or the second offset indicated by the network device, determine the parameter value of the first offset and / or the parameter value of the second offset in the configuration of the same parameter.

[0139] Taking the number and / or order of first offsets indicated by network devices as an example, for instance, if the network device indicates that the value of the first offset precedes the value of the second offset, or if the network device does not indicate the order, and the terminal device defaults to determining that the value of the first offset precedes the value of the second offset: When all multiple first offsets are indicated by multiple SMTCs, for example, one first offset is indicated by a base SMTC and other first offsets are indicated by other SMTCs, then the first (N-offset-1) parameter values ​​in the same parameter configuration are used as the other first offsets; when all multiple first offsets are indicated by only the same parameter configuration in the same SMTC, then the first N-offset parameter values ​​in the same parameter configuration are used as the first offsets. If the network device indicates that the value of the first offset follows the value of the second offset, then the aforementioned first (N-offset-1) parameter values ​​or first N-offset parameter values ​​are replaced with the last (N-offset-1) parameter values ​​or last N-offset parameter values.

[0140] When the third SMTC and the fourth SMTC belong to the same SMTC list, at least one of the first offsets and at least one of the second offsets are configured using different SMTCs within the same SMTC list, and / or at least one cell or at least one SSB is indicated in each SMTC configuration. The terminal device receives or measures the at least one cell or at least one SSB indicated in the same SMTC configuration based on the offsets in each SMTC configuration.

[0141] If the terminal device determines that the cell is the first cell or the SSB is the first SSB based on the first information indicated by the network device, then the SMTC (third SMTC) is configured with the first offset; if the terminal device determines that the cell is the second cell or the SSB is the second SSB based on the first information indicated by the network device, then the SMTC (fourth SMTC) is configured with the second offset.

[0142] For example, if the cell is included in one or more first cells indicated in the first information, then the cell is a first cell; or if the SSB is included in one or more first SSBs indicated in the first information, then the SSB is a first SSB; or if the cell is not included in one or more long-cycle cells indicated in the first information, then the cell is a first cell; or if the SSB is not included in one or more long-cycle SSBs indicated in the first information, then the SSB is a first SSB.

[0143] For example, if the cell is included in one or more second cells indicated in the first information, then the cell is a second cell; or if the SSB is included in one or more second SSBs indicated in the first information, then the SSB is a second SSB; or if the cell is included in one or more long-cycle cells indicated in the first information, then the cell is a second cell; or if the SSB is included in one or more long-cycle SSBs indicated in the first information, then the SSB is a second SSB.

[0144] In this embodiment of the application, the terminal device may use the third cell as the second cell, and / or the terminal device may use other cells besides the third cell as the first cell;

[0145] Alternatively, “the third cell is designated as the second cell” can be replaced with “at least one of the second cells is indicated by the third cell”.

[0146] In this embodiment of the application, the terminal device may use the third SSB as the second SSB, and / or the terminal device may use any other SSB other than the third SSB as the first SSB.

[0147] Alternatively, “the third SSB is used as the second SSB” can be replaced with “at least one of the second SSBs is indicated by the third SSB”.

[0148] After determining the first measurement window and the second measurement window, in operation 302, the terminal device receives and / or measures the first SSB in the first measurement window, and receives and / or measures the second SSB in the second measurement window. The specific methods for receiving and / or measuring the first and second SSBs can be found in relevant technologies and will not be elaborated here.

[0149] Figure 4 is a timing diagram of receiving and / or measuring a first SSB and a second SSB according to an embodiment of this application. As shown in Figure 4(a), the terminal device determines a first measurement window based on a first period, a first offset, and a first duration, and receives and / or measures the first SSB within the first measurement window; the terminal device determines a second measurement window based on a second period, a second offset, and a second duration, and receives and / or measures the second SSB within the second measurement window.

[0150] In addition, the network device can also indicate multiple first offsets and multiple second offsets, as shown in Figure 4(b). Within a first period, two first measurement windows are determined based on two different first offsets, namely first offset 1 and first offset 2, and the first SSB is received and / or measured in these two first measurement windows respectively. Similarly, within a second period, two second measurement windows are determined based on two different second offsets, namely second offset 1 and second offset 2, and the second SSB is received and / or measured in these two second measurement windows respectively.

[0151] During the initial access process, for a half-frame containing an SSB that appears in the second period (e.g., 160ms), if the terminal device still receives the SSB in the first period (e.g., 20ms), it may not be able to detect a valid SSB signal at multiple expected locations of the terminal device. These invalid detections, in addition to wasting power, may also affect the terminal device's assessment of the SSB signal quality, thereby affecting the possibility of the terminal device using the SSB for access or handover. For a half-frame containing an SSB that appears in the first period (e.g., 20ms), if the terminal device receives the SSB in the first period (e.g., 160ms), it may affect the access time and the success rate of handover.

[0152] Since the terminal device may obtain the network device configuration during the initial access phase, it is impossible to determine the period of the SSB to be detected. Therefore, it is necessary to first determine the period of receiving and / or measuring the SSB, then determine the offset of the half-frame containing different SSBs within the measurement period, and finally complete the measurement of different SSBs.

[0153] In this embodiment of the application, the method may further include: the terminal device determining the period used to receive and / or measure the SSB during the initial access phase.

[0154] For example, the terminal device determines the period used to receive and / or measure the SSB during the initial access phase, including at least one of the following:

[0155] At the start of initial access, the terminal device uses the first period (e.g., 20ms) or the second period (e.g., 160ms) as the default period for receiving SSB, and / or, after access is completed, determines the period for receiving and / or measuring SSB according to the SMTC configuration of the network device.

[0156] During the initial first time period after initial access, the terminal device uses a first period (e.g., 20ms) as the default period for receiving SSBs. Based on the length of this first time period and the number of received SSBs, it determines the period for receiving and / or measuring SSBs, and then receives and / or measures SSBs according to the determined period. Alternatively, during an initial time period no longer than the second period (e.g., 160ms), the terminal device uses the first period as the default period for receiving and / or measuring SSBs. When multiple SSBs are received, the terminal device determines that the period for receiving and / or measuring SSBs is the first period. When fewer than two SSBs are received, the terminal device determines that the period for receiving and / or measuring SSBs is the first period. The period for measuring the SSB is the second period; for example, the length of the first time period is T, T is greater than or equal to 160ms, for example M = T / 160 (rounded down), and M is greater than 0. If the number of SSBs received by the terminal device N > M, then the terminal device determines that the period for receiving and / or measuring the SSB is 20ms. If N ≤ M, then the terminal device determines that the period for receiving and / or measuring the SSB is 160ms. In addition, it also includes the terminal device using 20ms as the default period for receiving and / or measuring SSBs within an initial time period of no more than 160ms. If multiple SSBs are received, then the terminal device determines that the period for receiving and / or measuring the SSB is 20ms.

[0157] When the terminal device starts to access the system, it uses the first cycle (e.g., 160ms) as the default cycle for receiving and / or measuring SSB. When access fails, for example, if no SSB is received or the strength or quality of the received SSB signal is lower than a specified threshold, it uses the second cycle (e.g., 160ms) as the default cycle for receiving and / or measuring SSB and tries to receive and / or measure SSB again.

[0158] The terminal device uses the first period (e.g., 20ms) as the period for receiving and / or measuring an SSB. When an SSB is received, it uses the SSB to measure and evaluate the SSB, and / or decodes the MIB in the SSB, and / or determines the period for receiving and / or measuring the SSB according to the indication in the MIB, and / or uses the SSB for initial access. That is, once an SSB is received, the SSB is measured and evaluated using the instantaneous SSB, without performing filtering or averaging based on multiple first SSBs before evaluating the first SSB, and / or decoding the MIB in the instantaneous SSB, and determining the period for receiving or measuring the SSB according to the indication in the MIB.

[0159] The terminal device uses the first cycle (e.g., 20ms) as the cycle for receiving and / or measuring SSBs, and continues to receive and / or measure SSBs until the number of SSB signals received meets a preset condition. Based on the number of SSB signals received that meet the preset condition, the terminal device decodes the MIB and / or the SIB associated with the SSB (e.g., SIB1, SIB19) in the SSB, and determines the cycle for receiving and / or measuring the SSB based on the indications in the MIB and / or the SIB, and / or evaluates whether it is suitable to make initial access through the SSB.

[0160] As can be seen from the above embodiments, when there may be surrounding cells using NR NTN downlink enhancement technology, the terminal device can use two different cycles, namely the first cycle and the second cycle, to receive and / or measure SSBs in multiple measurement windows with different offsets. Therefore, when the activation interval of the satellite beam is long, the corresponding cell can not only measure cells that transmit SSBs according to the second cycle (e.g., 160ms) as a long cycle, but also cells that transmit SSBs according to the first cycle (e.g., 20ms) as a short cycle. This avoids the power consumption of the terminal device and the problem of filtering smoothing caused by over-measurement, while also taking into account the measurement efficiency of measuring cells that transmit SSBs according to the short cycle.

[0161] In addition, the terminal device can also perform initial access based on the characteristics of the received SSB signal.

[0275] In this application embodiment, when the third SMTC and the fourth SMTC are the same SMTC, at least one first offset and at least one second offset are configured using different parameters within the same SMTC; or, at least one first offset and at least one second offset are configured using the same parameter within the same SMTC, and the terminal device determines the parameter value of the first offset and / or the parameter value of the second offset in the configuration of the same parameter; and / or,

[0276] In the case where the third SMTC and the fourth SMTC belong to the same SMTC list, at least one of the first offsets and at least one of the second offsets are configured using different SMTCs in the same SMTC list, and / or, at least one cell or at least one SSB is indicated in each SMTC configuration.

[0277] In this embodiment of the application, the terminal device determines the parameter value of the first offset and / or the parameter value of the second offset in the configuration of the same parameter, including:

[0278] In the configuration of the same parameter, at least one parameter value within the first period range is determined as at least one of the first offsets, and at least one other parameter value in the configuration of the same parameter is determined as at least one of the second offsets; or,

[0279] In the configuration of the same parameter, the first half of the parameter value is determined to be at least one of the first offsets, and the second half of the parameter value is determined to be at least one of the second offsets; or,

[0280] Based on the number and / or order of the first offset and / or the second offset indicated by the network device, determine the parameter value of the first offset and / or the parameter value of the second offset in the configuration of the same parameter.

[0281] In this embodiment of the application, the terminal device determines the period used to receive and / or measure the SSB during the initial access phase.

[0282] In this embodiment of the application, the terminal device determines the period used to receive and / or measure the SSB during the initial access phase, including at least one of the following:

[0283] At the start of initial access, the terminal device uses the first cycle or the second cycle as the default cycle for receiving SSBs, and / or, after access is completed, determines the cycle for receiving and / or measuring SSBs according to the SMTC configuration of the network device.

[0284] During the initial first time period after initial access, the terminal device uses the first period as the default period for receiving SSBs, and determines the period for receiving and / or measuring SSBs based on the length of the first time period and the number of SSBs received. Then, it receives and / or measures SSBs according to the determined period. Alternatively, during the initial time period not exceeding the second period, the terminal device uses the first period as the default period for receiving and / or measuring SSBs. When multiple SSBs are received, the terminal device determines that the period for receiving and / or measuring SSBs is the first period. When the number of SSBs received is less than two, the terminal device determines that the period for receiving and / or measuring SSBs is the second period.

[0285] When the initial access begins, the terminal device uses the first cycle as the default cycle for receiving and / or measuring SSB. When the access fails, it uses the second cycle as the default cycle for receiving and / or measuring SSB and tries to receive and / or measure SSB again.

[0286] The terminal device uses the first cycle as the cycle for receiving and / or measuring an SSB. When an SSB is received, it uses the SSB to measure and evaluate the SSB, and / or decodes the MIB in the SSB, and / or determines the cycle for receiving and / or measuring the SSB according to the indication of the MIB, and / or uses the SSB for initial access.

[0287] The terminal device uses the first cycle as the cycle for receiving and / or measuring SSBs, and continues to receive and / or measure SSBs until the number of SSB signals received meets a preset condition. Based on the number of SSB signals received that meet the preset condition, the terminal device decodes the MIB and / or the SIB associated with the SSB (e.g., SIB1, SIB19) in the SSB, and determines the cycle for receiving and / or measuring the SSB based on the indications in the MIB and / or the SIB, and / or evaluates whether it is suitable to make initial access through the SSB.

[0288] As can be seen from the above embodiments, when there may be surrounding cells using NR NTN downlink enhancement technology, the terminal device can use two different cycles, namely the first cycle and the second cycle, to receive and / or measure SSBs in multiple measurement windows with different offsets. Therefore, when the activation interval of the satellite beam is long, the corresponding cell can not only measure cells that transmit SSBs according to the second cycle (e.g., 160ms) as a long cycle, but also cells that transmit SSBs according to the first cycle (e.g., 20ms) as a short cycle. This avoids the power consumption of the terminal device and the problem of filtering smoothing caused by over-measurement, while also taking into account the measurement efficiency of measuring cells that transmit SSBs according to the short cycle.

[0289] In addition, the terminal device can also perform initial access based on the characteristics of the received SSB signal.

[0346] Fifth aspect of the embodiment

[0347] This application provides a terminal device that includes an SSB measuring device according to an embodiment of the third aspect.

[0348] Figure 8 is a schematic block diagram of the system configuration of a terminal device according to an embodiment of this application. As shown in Figure 8, the terminal device 800 may include a processor 810 and a memory 820; the memory 820 is coupled to the processor 810. It is worth noting that this figure is exemplary; other types of structures may also be used to supplement or replace this structure to implement telecommunications functions or other functions.

[0349] In one implementation, the function of the SSB's measuring device can be integrated into the processor 810.

[0350] The processor 810 is configured such that: the terminal device determines a first measurement window based on a first cycle and a first offset, and determines a second measurement window based on a second cycle and a second offset; the terminal device receives and / or measures a first SSB (SS / PBCH block) in the first measurement window, and receives and / or measures a second SSB in the second measurement window.

[0351] In another embodiment, the SSB measuring device can be configured separately from the processor 810. For example, the SSB measuring device can be configured as a chip connected to the processor 810, and the function of the SSB measuring device can be realized through the control of the processor 810.

[0352] As shown in Figure 8, the terminal device 800 may further include: a communication module 830, an input unit 840, a display 850, and a power supply 860.

[0360] In one implementation, the function of the SSB measurement indicator can be integrated into the processor 910.

[0361] The processor 910 can be configured such that the network device sends first information to the terminal device, the first information including at least a first period and / or a second period, the first period being used to indicate the period during which the terminal device receives and / or measures a first SSB, and the second period being used to indicate the period during which the terminal device receives and / or measures a second SSB.

[0362] In another embodiment, the SSB measurement indicator can be configured separately from the processor 910. For example, the SSB measurement indicator can be configured as a chip connected to the processor 910, and the function of the SSB measurement indicator can be realized through the control of the processor 910.

[0363] In addition, as shown in Figure 9, the network device 900 may also include a transceiver 940 and an antenna 950, etc.; the functions of the above components are similar to those in the prior art, and will not be described in detail here. It is worth noting that the network device 900 does not necessarily have to include all the components shown in Figure 9; furthermore, the network device 900 may also include components not shown in Figure 9, which can be referred to in related technologies.

[0364] As can be seen from the above embodiments, when there may be surrounding cells using NR NTN downlink enhancement technology, the terminal device can use two different cycles, namely the first cycle and the second cycle, to receive and / or measure SSBs in multiple measurement windows with different offsets.
