[0002] This application claims priority to Chinese Patent Application No. 202410577996.6, filed in China on May 10, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, specifically relating to a method, apparatus, terminal and network-side equipment for receiving and transmitting a Synchronization Signal Block (SSB). Background Technology

[0004] In some related technologies, terminals often directly receive SSBs using a default 20-millisecond (ms) period. This direct adherence to the default 20ms period leads to a low success rate in receiving SSBs. For example, in non-terrestrial network (NTN) scenarios, due to the large coverage area, satellites require a large number of beams for coverage. However, due to the limitations of satellite hardware, the number of beams that can be activated simultaneously is limited. Therefore, for terminals within a certain beam's coverage area, a satellite signal cannot be guaranteed at all times. During the initial access phase, the terminal assumes an SSB period of 20ms and attempts to receive SSBs. However, in some satellite coverage areas, beam coverage may not exist within the 20ms period, causing the terminal to be unable to receive SSBs for a certain period. Therefore, the terminal suffers from a low success rate in receiving SSBs. Summary of the Invention

The term "base station" is not limited to any specific technical terminology. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0064] Core network equipment, also known as core network nodes, core network functions, or core network elements, includes, but is not limited to, at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (or L-NEF), and Binding Support.

It should be noted that this application embodiment only uses core network equipment in the NR system as an example and does not limit the specific type of core network equipment. If the name of the core network equipment mentioned in this application embodiment changes in subsequent protocol versions (e.g., 6G), it will still be within the scope of protection of this application.

[0065] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0066] In some embodiments, a satellite system supporting beam hopping can include, as shown in Figure 2, a network management center (NCC), a gateway station (GW), satellites equipped with flexible payloads, and terminals.

[0067] Among them, the forward link from the gateway station to the terminal can adopt a beam-hopping working mode compatible with the DVB-S2X protocol, which sends the data stream of the gateway station to the satellite in time division multiplexing (TDM) mode, and switches different data streams to different beams through the satellite beam-hopping controller.

[0068] The reverse link references the DVB-RCS2 protocol. The terminal accesses the satellite in the form of Multi-Frequency Time Division Multiple Access (MF-TDMA) and transmits the data transparently to the ground gateway station or network control center through the satellite to establish a communication link between user terminals, thereby realizing the interconnection between any user terminals.

[0069] The NCC (Network Control Center) manages the entire satellite communication network. Its main functions include generating beam hopping control commands, user access control, resource allocation and management, user information management, system network management, system service statistics, and user cost statistics. The Network Control Center allocates time slot resources based on each user's service needs and generates a beam hopping time schedule, including parameters such as beam dwell time, beam hopping period, and revisit time. Satellite beam switching is performed synchronously according to this schedule.

[0070] Beam hopping technology, based on time slicing, achieves traditional multi-beam coverage with fewer beams, thus reducing the number of antennas required for satellites and facilitating satellite miniaturization. Compared to traditional resource allocation methods, Low Earth Orbit (LEO) satellites with BH antenna payloads can flexibly allocate resources in four dimensions: space, time, bandwidth, and power. This allows them to better adapt to non-uniform traffic demand distributions and highly dynamic topologies, thereby improving resource utilization and energy efficiency. The core of this technology research is the optimal allocation / scheduling of resources, including time, frequency, space, power, and energy efficiency.

[0071] The configuration information and working mechanism of hopping beams are shown in Figure 3. The parameters in Figure 3 are explained as follows:

[0072] Beam Hopping Slot (BHS), also known as beam dwell time, refers to the minimum duration allocated to a beam. The number of slots allocated to each beam can be determined based on Quality of Service (QoS) or capacity requirements. As the time carrier of physical frames, BHS is typically on the order of milliseconds.

[0073] The Beam Hopping Period (BHP) refers to the time required to traverse the assigned BHS sequence once. The number of BHS assigned to each beam can be obtained by a specific time slot allocation algorithm, and the cluster set of each beam and the order of the assigned BHS in the Beam Hopping Period can be obtained by designing the Beam Hopping Pattern.

[0074] Slot switch (SS), also known as protection time, physically refers to the time delay required for one beam to switch to another, typically on the order of microseconds. Switching can occur after each BHS (Band of Halves), or after multiple BHS (a beam may have multiple BHS). A dummy symbol block is usually set at the end of the service frame for switch protection.

[0075] Beam Revisit Time (RVT) is the interval between BHS resource blocks allocated to a beam. Because an excessively long beam revisit time can affect user terminal synchronization, even if a beam has no service demand within a specific beam hopping period (a beam in a non-hotspot area), a BHS should still be allocated within that period to send synchronization, broadcast, and other signaling messages in that time slot.

[0076] The hop number (HN) can also be called the hop beam slot number.

[0077] Beam Hopping Time Plan (BHTP) can take into account a combination of factors such as user requests, service forecasts, service awareness, or system resources. It is generated in advance by the NCC or service provider and sent to the satellite and ground systems.

[0078] The SSB receiving method, sending method, apparatus, terminal, and network-side equipment provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0079] Please refer to Figure 4, which is a flowchart of an SSB receiving method provided in an embodiment of this application. As shown in Figure 4, it includes the following steps:

[0080] Step 401: The terminal receives the SSB based on at least one of the transmission pattern information and frequency information;

[0081] The transmitted pattern information includes at least one of the following:

[0082] Beam hopping pattern information, SSB transmission activation pattern information, cell DTX pattern information, cell DRX pattern information;

[0083] The frequency information includes at least one of the following:

[0084] Frequency range, frequency band, frequency zone, frequency point.

[0085] The aforementioned transmission pattern information may be configured by the network-side equipment or agreed upon by the protocol. The aforementioned frequency information may be configured by the network-side equipment or agreed upon by the protocol.

[0086] The aforementioned hopping beam pattern information is used to explicitly or implicitly indicate the hopping beam pattern, which represents the transitions between beams, such as explicitly or implicitly indicating the hopping beam pattern shown in Figure 3 or Figure 5.

[0087] The aforementioned SSB transmission activation pattern information is used to explicitly or implicitly indicate the SSB transmission activation pattern, which represents the activation and inactivation times of SSB transmission, such as explicitly or implicitly indicating the SSB transmission activation pattern shown in Figure 6 or Figure 7.

[0088] The aforementioned cell DTX pattern information is used to explicitly or implicitly indicate the DTX pattern, which represents the transmission time and non-transmission time. For example, the DTX pattern shown in Figure 8 explicitly or implicitly indicates the DTX pattern. In this DTX pattern, the DTX period is 80ms, where "ON" indicates transmission and the state lasts for 50ms, and "OFF" indicates non-transmission and the state lasts for 30ms.

[0089] The aforementioned cell DRX pattern information is used to explicitly or implicitly indicate the DRX pattern, which represents the receiving time and the non-receiving time. For example, the DRX pattern shown in Figure 9 is explicitly or implicitly indicated. In this DRX pattern, the DRX period is 200ms, where "ON" indicates receiving and lasts for 160ms, and "OFF" indicates not receiving and lasts for 40ms.

[0090] In some implementations, the aforementioned frequency range (Radio Frequency, FR), frequency band, frequency zone, or frequency point can be the frequency range, frequency band, frequency zone, or frequency point where the frequency resources of the aforementioned SSB are located. This is not limited; for example, in some implementations, the aforementioned frequency range, frequency band, frequency zone, or frequency point can be the frequency range, frequency band, frequency zone, or frequency point where an SSB may exist, i.e., the frequency range, frequency band, frequency zone, or frequency point corresponding to a potential SSB; or, the aforementioned frequency range, frequency band, frequency zone, or frequency point is configured by the network-side equipment for the aforementioned terminal.

[0091] In some implementations, the aforementioned FR may include FR1 or FR2, the aforementioned frequency band may include the 2.4 GHz band, the 5 GHz band, the S band, or the Ka band, the aforementioned frequency band may include frequency band n255 or frequency band n256, and the aforementioned frequency point may be the Absolute Radio Frequency Channel Number (ARFCN).

[0092] In this embodiment of the application, receiving an SSB can also be referred to as detecting an SSB.

[0093] In this embodiment, the terminal receives an SSB based on at least one of transmission pattern information and frequency information. The transmission pattern information includes at least one of the following: beam hopping pattern information, SSB transmission activation pattern information, cell DTX pattern information, and cell DRX pattern information. The frequency information includes at least one of the following: frequency range, frequency band, frequency zone, and frequency point. Because the terminal receives the SSB based on at least one of the transmission pattern information and frequency information, it is easier for the terminal to receive the SSB, thereby improving the success rate of SSB reception, which can also be referred to as the detection success rate.

[0094] For example, based on the beam hopping pattern information, the time or period corresponding to the beam that the network-side device transmits SSB can be determined, and the SSB can be received within that time or period. Alternatively, the SSB can be received during the SSB transmission activation time based on the SSB transmission activation pattern information. Or, the SSB can be received during the transmission time based on the cell DTX pattern information. Or, the SSB can be received during the reception time based on the cell DRX pattern information. Alternatively, the SSB can be received within the frequency range, frequency band, frequency zone, or frequency point based on the frequency range, frequency band, frequency zone, or frequency point. This makes it easier for the terminal to receive the SSB, thereby improving the success rate of the terminal receiving the SSB.

[0095] In this embodiment of the application, it can be applied to both non-terrestrial networks (NTN) and terrestrial networks (TN). That is, the SSB mentioned above can be an SSB sent by the network-side equipment of the NTN, such as an SSB sent by a satellite received by a terminal, or the SSB mentioned above can be an SSB sent by the network-side equipment of the TN, such as an SSB sent by a base station received by a terminal.

[0096] As an optional implementation, the terminal receives the SSB based on at least one of the transmission pattern information and frequency information, including at least one of the following:

[0097] The terminal receives an SSB based on the transmitted pattern information and the first SSB cycle, wherein the first SSB cycle includes: the SSB cycle agreed upon by the network configuration or protocol;

[0098] The terminal determines the second SSB cycle based on the transmitted pattern information and receives SSBs according to the second SSB cycle;

[0099] The terminal determines the third SSB cycle based on the frequency information and receives SSBs according to the third SSB cycle.

[0100] The first SSB period mentioned above can be a predefined or network-configured SSB period. For example, for a terminal that is initially accessing the network, the first SSB period is 20ms, and there is no limitation on this. The first SSB period can also be 10ms or 40ms, etc.

[0101] Since SSBs are received based on the transmission pattern information and the first SSB period, this avoids the terminal directly receiving SSBs according to the first SSB period, making it easier for the terminal to receive SSBs and improving the success rate of SSB reception. For example, the time or period corresponding to the beam that the network-side device transmits the SSB is determined based on the beam hopping pattern information, and the SSB is received according to the first SSB period within that time or period; or, the SSB is received according to the SSB transmission activation pattern information within the SSB transmission activation time within the first SSB period; or, the SSB is received according to the cell DTX pattern information within the transmission time within the first SSB period; or, the SSB is received according to the cell DRX pattern information within the reception time within the first SSB period, making it easier for the terminal to receive SSBs and improving the success rate of SSB reception.

[0102] The aforementioned second SSB period can be an extended SSB period, with a duration longer than the aforementioned first SSB period, such as 40ms, 80ms, 100ms, 120ms, 160ms, etc. The terminal determines the second SSB period based on the transmission pattern information by either determining the second SSB period according to the mapping relationship between the transmission pattern information and the second SSB period, or by calculating the second SSB period based on the transmission pattern information using a calculation method agreed upon in the protocol. There is no specific limitation on this; for example, the second SSB period can be selected from SSB periods longer than the first SSB period based on the transmission pattern information.

[0103] Receiving SSBs according to the second SSB cycle makes it easier for the terminal to receive them, thus improving the success rate of SSB reception. For example, in NTN scenarios, some satellite coverage areas may not have beam coverage within a 20ms cycle, which may cause the terminal to be unable to receive SSBs for a certain period of time. The second SSB cycle is determined by the aforementioned transmission pattern information. This can be achieved by extending the SSB transmission cycle, meaning the terminal receives SSBs based on a longer SSB transmission cycle, thereby increasing the number of effectively received SSBs and ensuring SSB detection performance; or by having the network actually send SSBs for a longer period, allowing the terminal to receive SSBs based on a longer SSB transmission cycle, which can reduce unnecessary SSB detection attempts and improve the terminal's energy efficiency.

[0104] The aforementioned third SSB period can be an extended SSB period, with a duration longer than the aforementioned first SSB period, such as 40ms, 80ms, 100ms, 120ms, 160ms, etc. Specifically, the terminal determines the third SSB period based on the frequency information by determining it according to the mapping relationship between the frequency information and the third SSB period, or by pre-defining or configuring the third SSB period for the aforementioned frequency information, or by calculating the aforementioned third SSB period based on the frequency information using a calculation method agreed upon in the protocol, etc. There are no specific limitations on this; for example, the aforementioned third SSB period can be selected from SSB periods longer than the first SSB period based on the frequency information.

[0105] Receiving SSBs according to the third SSB cycle makes it easier for the terminal to receive SSBs, thus improving the success rate of SSB reception. For example, by determining the extended SSB cycle based on the frequency information mentioned above to obtain the aforementioned third SSB, the terminal receives SSBs based on a longer SSB cycle, increasing the number of effectively received SSBs and ensuring SSB detection performance; or, if the network side actually transmits SSBs for a longer period, the terminal receives SSBs based on a longer SSB transmission cycle, reducing unnecessary SSB detection attempts and improving the terminal's energy efficiency.

[0106] As an optional implementation, the hopping beam pattern information is used to indicate the beam activation pattern of the network-side device.

[0107] The aforementioned beam activation pattern can be the activation pattern of the beam coverage area of ​​the network-side device, such as the hopping beam pattern shown in Figure 3 or Figure 5.

[0108] In this embodiment, since the hopping beam pattern information is used to indicate the beam activation pattern of the network-side device, the terminal can determine the activation time of the beam corresponding to the terminal or the beam that transmits the SSB based on the beam activation pattern, and receive the SSB within the activation time, or determine the hopping beam period based on the beam activation pattern, and receive the SSB with the first SSB within the hopping beam period, thereby improving the success rate of the terminal receiving the SSB.

[0109] As an optional implementation, the hopping beam pattern information includes at least one of the following:

[0110] Beam skipping duration, BHP, beam switching time, RVT, HN, BHTP of at least one beam, and maximum beam revisit time.

[0111] The aforementioned hopping beam duration can be a BHS or beam dwell time, and the hopping beam duration can include one or more time slots, specifically the minimum duration allocated to a beam.

[0112] By using the aforementioned hopping beam duration, the terminal can determine the duration of the beam, thereby receiving SSBs based on that duration and improving the performance of SSB reception.

[0113] The aforementioned BHP refers to the time required to traverse the assigned beam hopping duration (such as BHS) sequence once.

[0114] The aforementioned BHP allows the terminal to receive SSBs within the BHP, thereby improving the performance of SSB reception.

[0115] The aforementioned beam switching time can also be called the guard time. Its physical meaning is the time delay required for one beam to switch to another, which is generally on the order of microseconds.

[0116] By adjusting the beam switching time, the terminal can better predict the duration of the next beam, thus enabling it to receive SSBs more effectively and improving its SSB reception performance.

[0117] The aforementioned RVT is the interval time between the hopping beam duration resource blocks allocated to the beam. The RVT of at least one beam can be the RVT of at least one beam that repeats within a BHP, such as beam 1 and beam 5 in Figure 5.

[0118] The RVT of at least one of the aforementioned beams enables the terminal to receive SSBs within the corresponding beam's RVT, thereby improving the performance of SSB reception.

[0119] In some implementations, since excessive beam revisit time may affect terminal synchronization, even if a beam has no service demand in a specific BHP (such as a beam in a non-hotspot area), a beam hopping duration can be allocated within the period to send synchronization, broadcast and other signaling during that beam hopping duration.

[0120] The aforementioned HN can also be referred to as the hopping beam slot number or hopping beam duration number, such as the HN corresponding to the duration of each hopping beam within the BHP.

[0121] The aforementioned HN allows the terminal to receive SSBs during the duration of the hopping beam corresponding to its own HN, thereby improving the performance of SSB reception.

[0122] The aforementioned BHTP is used to represent the beam hopping plan of network-side equipment, as shown in Figure 3 or Figure 5.

[0123] The BHTP terminal described above can determine the beam hopping plan, thereby receiving SSBs within the duration of the corresponding beam, thus improving the performance of SSB reception.

[0124] The maximum beam revisit time mentioned above represents the maximum allowed beam revisit time within the BHP, such as 640ms or 320ms.

[0125] The aforementioned maximum beam revisit time terminal can receive SSBs within the maximum beam revisit time, thereby improving the performance of SSB reception.

[0126] It should be noted that all or part of the above-mentioned beam hopping pattern information may be agreed upon by the protocol or pre-configured, and some of the content of beam hopping duration, BHP, beam switching time, RVT, HN, BHTP of at least one beam, and maximum beam revisit time may not be included in the above-mentioned beam hopping pattern information. For example, based on the relationship between beam hopping duration, BHP, beam switching time, RVT, HN, BHTP of at least one beam, and maximum beam revisit time, other content can be derived or calculated from one or more of the content. For example, beam hopping duration can be derived or calculated based on beam switching time, BHP or beam switching time can be derived or calculated based on beam hopping duration, and beam hopping duration, BHP, beam switching time, RVT, HN or maximum beam revisit time of at least one beam can be derived or calculated based on BHTP, etc., without specific limitations.

[0127] In some implementations, when the transmission pattern information includes the beam hopping pattern information, the terminal receives an SSB based on the transmission pattern information and the first SSB period, including at least one of the following:

[0128] The terminal receives an SSB according to the first SSB period within the beam hopping period, wherein the beam hopping period is the beam hopping period included in the beam hopping pattern information, or the beam hopping period is the beam hopping period determined based on the beam hopping pattern information, or the beam hopping period is a pre-configured or protocol-agreed beam hopping period.

[0129] The terminal receives an SSB according to the first SSB cycle within the RVT corresponding to the target HN. The RVT is the RVT included in the beam hopping pattern information, or the RVT is the RVT determined based on the beam hopping pattern information. The target HN is the HN corresponding to the terminal, or the target HN is the HN included in the beam hopping pattern information, or the target HN is the HN determined based on the beam hopping pattern information, or the target HN is a pre-configured or protocol-defined HN.

[0130] The aforementioned beam hopping period, which is determined based on the beam hopping pattern information, can be understood as the beam hopping pattern information not including the beam hopping period. The beam hopping period is determined based on the beam hopping pattern information, such as the beam hopping period determined based on at least one of the following in the beam hopping pattern information: BHTP, beam hopping duration, beam switching time, and RVT of at least one beam.

[0131] In the above embodiments, since the SSB is received according to the first SSB cycle within the beam-hopping period, the terminal can more easily receive the SSB, thereby improving the success rate of the terminal receiving the SSB. Taking the beam-hopping pattern information in Figure 5 as an example, within a beam-hopping period, some beams may be revisited, which will make the beam revisit time of that beam shorter than the beam-hopping period. In Figure 5, the beam-hopping period is 640ms, the beam revisit time of beam 5 is 160ms, and beam 3 is only visited once within a beam-hopping period, so the beam revisit time of beam 3 is 640ms. Assuming the terminal does not know the current HN or which beam it is in, and the beam hopping period is 640ms, then during initial access, the terminal continues to receive SSBs at the assumed first SSB period (e.g., 20ms). If the terminal fails to detect an SSB within a certain period, it may stop detecting SSBs for power saving purposes in the terminal implementation. However, since the beam hopping period is 640ms, the terminal can receive SSBs for at least 640ms of the first SSB period.

[0132] The aforementioned target HN can be one or more HNs within the BHP.

[0133] The RVT corresponding to the target HN mentioned above is the RVT of the beam corresponding to the target HN. If the beam does not repeat within the hopping beam period (BHP), then the RVT is equal to the hopping beam period. As shown in Figure 5, the hopping beam period is 640ms, the beam revisit time of beam 5 is 160ms, and beam 3 is only visited once within one hopping beam period, so the beam revisit time of beam 3 is 640ms.

[0134] The aforementioned RVT, which is determined based on the hopping beam pattern information, can be understood as the hopping beam pattern information not including this RVT. This RVT is determined based on the hopping beam pattern information, such as the RVT determined based on at least one of the following in the hopping beam pattern information: BHTP, hopping beam duration, beam switching time, and RVT of at least one beam.

[0135] The aforementioned target HN, which is determined based on the hopping beam pattern information, can be understood as HN not included in the hopping beam pattern information. The HN is determined based on the hopping beam pattern information, such as HN determined based on at least one of the following in the hopping beam pattern information: BHTP, hopping beam duration, beam switching time, and RVT of at least one beam.

[0136] In the above embodiments, since the SSB is received within the RVT corresponding to the target HN according to the first SSB cycle, the terminal can more easily receive the SSB, thereby improving the success rate of the terminal receiving the SSB. Taking the hopping beam pattern information diagram 5 as an example, assuming that the beam corresponding to the terminal's target NH is beam 5, then during the initial access, the terminal receives the SSB according to the first SSB cycle (e.g., a 20ms SSB cycle) in beam 5 with a beam revisit time of 160ms.

[0137] In some implementations, as shown in Figure 5, assuming the terminal is within the coverage area of ​​beam 5, the terminal can receive SSB according to the 20ms SSB period during initial access; if the terminal knows that the beam revisit time of the current beam 5 is 160ms, the terminal can also use the 160ms SSB period to receive SSB.

[0138] In some implementations, as shown in Figure 5, assuming the terminal is within the coverage area of ​​beam 3, the terminal can receive SSBs based on a 20ms SSB period during initial access. Knowing that the revisit time of beam 3 is 640ms, the terminal can also use a 640ms SSB period to receive SSBs. This 640ms SSB period can consist of four SSB periods of a maximum of 160ms each.

[0139] In some implementations, as shown in Figure 5, assuming the terminal does not know the current HN or which beam it is in, and the maximum beam revisit time specified in the protocol is 640ms, then during initial access, the terminal continues to receive SSBs with an assumed 20ms SSB period. If the terminal fails to detect an SSB within a certain period, it may stop detecting SSBs for power saving purposes in the terminal implementation. However, since the maximum beam revisit time is 640ms, the terminal can receive SSBs within 640ms with at least a 20ms SSB period.

[0140] As an optional implementation, when the transmission pattern information includes the beam hopping pattern information, one or more SSB indices correspond to one beam hopping duration. The beam hopping duration is the beam hopping duration included in the beam hopping pattern information, or the beam hopping duration is the beam hopping duration determined based on the beam hopping pattern information, or the beam hopping duration is a pre-configured or protocol-agreed beam hopping duration.

[0141] The aforementioned beam hopping duration, which is determined based on the beam hopping pattern information, can be understood as the beam hopping pattern information not including the beam hopping duration. The beam hopping duration is determined based on the beam hopping pattern information, such as the beam hopping duration determined based on at least one of the following in the beam hopping pattern information: BHTP, beam hopping duration, beam switching time, and RVT of at least one beam.

[0142] The above-mentioned one or more SSB indices corresponding to a single beam hopping duration can be one or more SSB indices corresponding to any beam hopping duration within the beam hopping pattern.

[0143] In some implementations, since one hop beam duration corresponds to one beam, it is also possible to have one or more SSB indices corresponding to one beam, such as one SSB index corresponding to a single beam.

[0144] In some implementations, since one HN corresponds to one hopping beam duration, it is also possible to have one HN corresponding to one or more SSB indices.

[0145] Because it corresponds to one or more SSB indices, this allows one or more SSBs to be transmitted within a single beam hopping duration, making it easier for the terminal to receive the SSBs and improving SSB reception performance. For example, as shown in Figure 10, the beam hopping duration is one beam hopping time slot, corresponding to 1ms. Beam 1 can correspond to multiple SSBs. For example, for Case A SSB pattern, beam 1 corresponds to 2 SSB indices; for Case B and Case CSSB patterns, beam 1 corresponds to 4 SSB indices. These SSB patterns are the SSB patterns defined in the protocol.

[0146] As an optional implementation, the SSB transmits activation pattern information to indicate at least one of the following:

[0147] SSB transmission period, active time of SSB transmission within the SSB transmission period, and inactive time of SSB transmission within the SSB transmission period.

[0148] The SSB transmission period mentioned above can be the SSB transmission period shown in Figure 6 or Figure 7. Within this period, part of the time is the active time for SSB transmission, and part of the time is the inactive time for SSB transmission. SSB is sent during the active time.

[0149] By using the aforementioned SSB transmission cycle, the terminal receives SSBs within the SSB transmission cycle, thereby improving the success rate of the terminal receiving SSBs.

[0150] The aforementioned SSB transmission activation time within the SSB transmission cycle refers to the period during which SSB transmission is active within the SSB transmission cycle, while the aforementioned SSB transmission inactivity time refers to the period during which SSB transmission is inactive within the SSB transmission cycle.

[0151] By utilizing the active or inactive SSB transmission time within the SSB transmission cycle, the terminal can receive SSBs during the active time, thereby improving the success rate of SSB reception.

[0152] If the SSB transmission activation pattern information is not within the SSB transmission cycle during the SSB transmission activation time or during the SSB transmission inactive time within the SSB transmission cycle, the terminal can determine the activation time or inactive time through the SSB transmission cycle.

[0153] In some implementations, the SSB transmission activation pattern information described above includes at least one of the following:

[0154] The pattern information of SSB transmission activation and deactivation times, SSB transmission cycle, the proportion of SSB transmission activation time within the SSB transmission cycle, and the proportion of SSB transmission deactivation time within the SSB transmission cycle.

[0155] The above at least one can be used to indicate the SSB transmission period, the active time of SSB transmission within the SSB transmission period, or the inactive time of SSB transmission within the SSB transmission period.

[0156] In some implementations, when the transmission pattern information includes the SSB transmission activation pattern information, the terminal determines a second SSB period based on the transmission pattern information and receives SSBs according to the second SSB period, including:

[0157] The terminal determines the second SSB period based on the SSB transmission activation pattern information and the first SSB period, and receives the SSB according to the second SSB period. The first SSB period includes the SSB period agreed upon by the network configuration or protocol.

[0158] The determination of the second SSB period based on the SSB transmission activation pattern information and the first SSB period can be achieved by extending the first SSB period based on the SSB transmission activation pattern information. The duration of the second SSB period can be equal to the SSB transmission activation time, or it can be greater than the SSB transmission activation time, etc., and there are no limitations on this.

[0159] Receiving SSBs according to the second SSB cycle makes it easier for the terminal to receive SSBs, thereby improving the success rate of the terminal receiving SSBs.

[0160] Optionally, receiving an SSB according to the second SSB cycle includes at least one of the following:

[0161] During the active time of SSB transmission within the SSB transmission cycle, SSB is received according to the second SSB cycle;

[0162] Specifically, during the inactive period of SSB transmission within the SSB transmission cycle, the terminal does not receive SSBs, or during the inactive period of SSB transmission within the SSB transmission cycle, the terminal receives SSBs according to the second SSB cycle.

[0163] In this embodiment, SSBs can be received according to the second SSB cycle during the activation time, thereby making it easier to receive SSBs and improving the success rate of terminal receiving SSBs.

[0164] The following example uses the SSB transmission activation pattern shown in Figure 6 or Figure 7.

[0165] In Figure 6, the SSB transmission activation pattern period of the network configuration is 120ms (=6*20ms), of which the activation time accounts for 80ms (4*20ms) and the inactive time accounts for 40ms (2*20ms). The patterns of the activation and inactive times are shown.

[0166] In Figure 6, the SSB transmission activation period configured in the network is 200ms (=10*20ms), of which the activation time occupies 100ms (3*20ms+2*20ms) and the inactive time occupies 100ms (2*20ms+3*20ms), showing the pattern of the activation and inactive times.

[0167] In some implementations, as shown in Figure 11, the terminal receives SSBs with the SSB transmission activation time (80ms) as the second SSB cycle.

[0168] It should be noted that the embodiments of this application are not limited to receiving SSBs according to the second SSB cycle within the SSB transmission activation time. For example, as shown in Figure 12, when the terminal receives SSBs with the SSB transmission activation time (80ms) as the SSB cycle, even if the timing point at which the terminal starts SSB detection is not aligned and no SSB is received in some cycles, the SSBs that the network side may send can still be detected normally in multiple second SSB cycles.

[0169] It should be noted that in the embodiments of this application, the SSB transmission activation pattern information is not limited to receiving SSB according to the second SSB cycle. For example, the SSB transmission activation pattern information can also be received according to the first SSB cycle. For example, the terminal only needs to receive SSB according to the first SSB cycle (such as a 20ms SSB cycle) during the SSB transmission activation time. During the non-activation time, it can not receive SSB.

[0170] As an optional implementation, when the transmitted pattern information includes at least one of cell DTX pattern information and cell DRX pattern information, the receiving of SSB according to the second SSB cycle includes at least one of the following:

[0171] Receive SSB according to the second SSB cycle within the DTX cycle;

[0172] During the DRX cycle, SSBs are received according to the second SSB cycle.

[0173] The aforementioned second SSB cycle can be an SSB cycle determined based on the cell DTX map information and the cell DRX map information. The second SSB cycle can be equal to multiple first SSB cycles, or the second SSB cycle can be greater than one first SSB cycle but less than two second SSB cycles. The second SSB cycle can be greater than the OFF time in the cell DTX map information and greater than the OFF time in the cell DRX map information.

[0174] In this embodiment, since the SSB is received according to the second SSB cycle within the DTX cycle or DRX cycle, the terminal can more easily receive the SSB, thereby improving the success rate of the terminal receiving the SSB.

[0175] As an optional implementation, when the transmitted pattern information includes cell DTX pattern information, the terminal receives an SSB based on the transmitted pattern information and the first SSB period, including:

[0176] The terminal receives the SSB according to the first SSB during the DTX transmission time of the cell;

[0177] Specifically, during the non-transmission period of the cell DTX, the terminal does not receive SSB; or, during the non-transmission period of the cell DTX, the terminal does not expect to receive SSB.

[0178] The aforementioned transmission time refers to the duration of "ON" in the cell DTX pattern, as shown in Figure 8. The aforementioned non-transmission time refers to the duration of "OFF" in the cell DTX pattern, as shown in Figure 8.

[0179] In this embodiment, since the SSB is received according to the first SSB during the cell DTX transmission time, the terminal can easily receive the SSB, thereby improving the success rate of the terminal receiving the SSB.

[0180] As an optional implementation, when the transmitted pattern information includes cell DRX pattern information, the terminal receives an SSB based on the transmitted pattern information and the first SSB period, including:

[0181] The terminal receives the SSB according to the first SSB within the reception time of the cell DRX;

[0182] Specifically, during the non-reception period of the cell DTX, the terminal does not receive SSB; or, during the non-reception period of the cell DTX, the terminal does not expect to receive SSB.

[0183] The aforementioned reception time refers to the duration of "ON" in the cell DRX pattern, as shown in Figure 9. The aforementioned non-reception time refers to the duration of "OFF" in the cell DRX pattern, as shown in Figure 9.

[0184] In this embodiment, since the SSB is received according to the first SSB within the reception time of the cell DRX, the terminal can easily receive the SSB, thereby improving the success rate of the terminal receiving the SSB.

[0185] The following examples, using Figures 8 and 9, illustrate this point:

[0186] In Figure 8, the DTX period is 80ms, with the "ON" state lasting for 50ms and the "OFF" state lasting for 30ms, as shown in the figure below.

[0187] In some implementations, the terminal only needs to detect / receive SSB during the assumed 20ms SSB period (first SSB period) during the "ON" state duration of the DTX cycle, and does not need to detect / receive SSB during the "OFF" state duration.

[0188] In some implementations, the terminal may also detect / receive SSBs using a second SSB period (80ms, determined by the state of the DTX period of 50ms and the first SSB period of 20ms).

[0189] In Figure 9, the DRX period is 200ms, with the "ON" state lasting for 160ms and the "OFF" state lasting for 40ms. The base station may send SSBs with a first SSB period of 20ms, but the current terminal is under the beam coverage area corresponding to SSB2.

[0190] In some implementations, the terminal only needs to receive SSBs during the "ON" state duration of the DRX cycle, either in the first SSB cycle or the second SSB cycle. During the "OFF" state duration, it may not receive SSBs. The second SSB cycle is determined to be 160ms based on the "ON" state duration of the DRX cycle and the first SSB cycle.

[0191] As an optional implementation, the transmission pattern information is determined by at least one of the following:

[0192] The location of the terminal is determined, the network is configured, the protocol is agreed upon, and pre-configured.

[0193] The frequency information is determined by at least one of the following:

[0194] Network configuration, protocol agreement, and pre-configuration.

[0195] The aforementioned determination of transmission pattern information based on the terminal's location can be achieved by determining the transmission pattern information according to a mapping relationship between location and transmission pattern information; alternatively, determining the transmission pattern information based on the terminal's location includes: determining the terminal's location and acquiring the transmission pattern information predefined or pre-configured for the terminal's location. For example, the terminal obtains location information (such as latitude and longitude) based on a Global Navigation Satellite System (GNSS), thereby acquiring the corresponding pre-configured or pre-defined transmission pattern information. Specifically, this could involve acquiring pre-configured or pre-defined SSB transmission activation pattern information, the beam coverage area where the terminal is located, or hopping beam pattern information, etc.

[0196] The above network configuration includes at least one of the following:

[0197] Configuration can be achieved through neighboring cell configuration information, TN cell SSB configuration, or non-cell defined synchronization signal block (NCD-SSB) configuration.

[0198] If the neighboring cell configuration information contains the above transmission pattern information or frequency information, the TN cell's SSB contains the above transmission pattern information or frequency information, and the NCD-SSB contains the above NCD-SSB configuration.

[0199] By configuring through neighboring cell configuration information, TN cell SSB configuration, and NCD-SSB configuration, it is possible to obtain transmission pattern information or frequency information before entering a certain cell, and then receive SSB based on the transmission pattern information or frequency information in that cell, thereby further improving the success rate of terminal receiving SSB.

[0200] As an optional implementation, the third SSB cycle includes one of the following:

[0201] The SSB period is predefined or preconfigured for the frequency information;

[0202] The SSB period corresponding to the minimum frequency band predefined or preconfigured for the frequency information;

[0203] The SSB period corresponding to the position of the sync raster is predefined or preconfigured for the frequency information;

[0204] The SSB period corresponding to the cell search time predefined or preconfigured for the frequency information;

[0205] The SSB period corresponding to the SSB position is predefined or preconfigured for the frequency information;

[0206] The SSB cycle for notifications from neighboring cells;

[0207] The period of the non-cell-defining SSB (NCD-SSB) notification is defined by the cell-defining SSB (CD-SSB).

[0208] The third SSB period mentioned above is longer than the first SSB period, such as 80ms, 160ms, 320ms, etc. For example, a specific long period (such as 80ms or 160ms, different from the default 20ms for TN) is predefined as the third SSB period for the aforementioned FR, frequency band, or frequency zone. Similarly, a specific long period is predefined as the third SSB period for a specific Time Division Duplex (TDD) or Frequency Division Duplex (FDD) frequency zone.

[0209] The aforementioned minimum frequency band, synchronization grid position, SSB position, or cell search time can be the minimum frequency band, synchronization grid position, or cell search time predefined by the aforementioned FR, frequency band, or frequency zone. This minimum frequency band, synchronization grid position, SSB position, or cell search time corresponds to an SSB period.

[0210] In some implementations, the cell search time can be used to limit the search time for the terminal to receive an SSB in the third SSB cycle, and if no SSB is found, the terminal can stop receiving an SSB.

[0211] This allows for the determination of the third SSB cycle by predefining or preconfiguring the minimum frequency band, synchronization grid position, SSB position, or cell search time for the aforementioned FR, frequency band (such as NTN band or specific frequency band), frequency band, synchronization grid position, SSB position, or cell search time.

[0212] The SSB period of the neighbor cell notification mentioned above can be the SSB period directly notified by the neighbor cell, or the frequency point or SSB location notified by the neighbor cell. The third SSB period is the SSB period corresponding to the frequency point or SSB location notified by the neighbor cell.

[0213] The aforementioned CD-SSB can be the CD-SSB of the NTN band, meaning that the period of the CD-SSB of the NTN band, i.e. the third SSB period, can be communicated through the NCD-SSB.

[0214] The above embodiments can determine the third SSB period in multiple ways, thereby enabling the terminal to receive SSBs more flexibly and more easily.

[0215] As an optional implementation, the method further includes at least one of the following:

[0216] The terminal receives a neighbor cell notification, which includes at least one of the following: frequency information, SSB location, SSB period, synchronization grid location, cell search time, and minimum frequency band.

[0217] The terminal receives an NCD-SSB, the NCD-SSB including neighbor cell configuration information, the neighbor cell configuration information including at least one of the following:

[0218] Frequency information, SSB location, SSB period, synchronization grid location, cell search time, minimum frequency band.

[0219] The SSB location, SSB period, synchronization grid location, cell search time, and minimum frequency band mentioned above are described in the corresponding descriptions of the above implementation methods and will not be repeated here.

[0220] In this implementation, the aforementioned relevant information can be obtained through neighbor cell notification or NCD-SSB, so that the terminal can better receive the SSB.

[0221] For example, in some implementations, the third SSB period is predefined as 80ms for NTN bands (such as n255, n256). In NTN scenarios, during initial access, the terminal always assumes that the initial access SSB reception will be performed with a third SSB period of 80ms. Additionally, a cell search time can be predefined; if the terminal fails to successfully detect an SSB within the cell search time, it can stop receiving SSBs.

[0222] For example, in some implementations, the third SSB period is predefined as 80ms for the TDD band of the NTN and 160ms for the FDD band of the NTN. This means that the terminal can assume that the SSB period of 80ms / 160ms is used for SSB reception on the corresponding band. In an NTN scenario, during initial access, the terminal always assumes an 80ms SSB period on the TDD band and a 160ms SSB period on the FDD band.

[0223] For example, in some implementations, when a terminal is in a TN cell near an NTN coverage area, the neighbor cell configuration information it receives may include configuration information that the neighbor cell is an NTN cell. This may include information such as the corresponding SSB period and synchronization grid position, which can help the terminal access the NTN cell more efficiently when it subsequently enters the NTN cell.

[0224] For example, in some implementations, when the terminal is in an NTN cell, the NCD-SSB received outside the initial BWP may carry configuration information including the neighboring cell being an NTN cell. This information may include the corresponding CD-SSB cycle, synchronization grid position, and other information, which can help the terminal access the NTN cell more efficiently when it subsequently enters the NTN cell.

[0225] In this embodiment, the terminal receives an SSB based on at least one of transmission pattern information and frequency information. The transmission pattern information includes at least one of the following: beam hopping pattern information, SSB transmission activation pattern information, cell DTX pattern information, and cell DRX pattern information. The frequency information includes at least one of the following: frequency range, frequency band, frequency zone, and frequency point. Because the SSB is received based on at least one of the transmission pattern information and frequency information, the terminal can more easily receive the SSB, thereby improving the success rate of SSB reception.
