Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method and device for searching neighboring cells of a different system, a storage medium, and a terminal device. Background Art

[0002] Currently, in the New Radio (NR) system, the User Equipment (UE) needs to measure the neighboring cells in order to switch or redirect the UE. The measurements include inter-frequency measurements and inter-system measurements within the NR system. When the UE performs these measurements, a special measurement gap is required. In the measurement gap, the UE specifically measures the neighboring cells and does not transmit other data information. When the resources configured to the UE are located in the measurement time window of the Gap in the time domain, the UE will not be able to transmit the corresponding information on these resources when performing inter-frequency / inter-system measurements, which will affect the user experience. The NR protocol introduces an RRM measurement time configuration window based on the synchronization signal block (SSB), called the SMTC window. The UE obtains the measurement period and time of all SSBs through the SMTC.

[0003] However, for NR and Long Term Evolution (LTE) multi-mode scenarios, due to the uncertainty of time alignment between LTE and NR systems, when the UE receives data according to the configured SMTC, it cannot be sure that there must be SSB in the SMTC window. The UE will not be able to search for neighboring cells according to the SMTC window configuration, and will not be able to establish a secondary cell group (SCG) or initiate a handover from LTE to NR, affecting the user experience. Summary of the invention

[0004] The present invention provides a heterosystem neighbor cell search method and device, a storage medium, and a terminal device, which can improve the success rate of neighbor cell search, and improve communication efficiency and user experience.

[0005] To solve the above technical problems, on the first aspect, an embodiment of the present invention provides a method for searching for neighboring cells of a different system. The method for searching for neighboring cells of a different system includes: detecting SSB within the SMTC window in the current measurement cycle; at least when SSB is not detected within the SMTC window of the current measurement cycle, iteratively moving the position of the SMTC window in the next measurement cycle, and detecting SSB within the SMTC window of the next measurement cycle, until SSB is detected within the SMTC window, and the position of the SMTC window after the movement is different from the position of the SMTC window before the movement; and reporting information on the detected SSB.

[0006] Optionally, moving the SMTC window to the position of the next SMTC measurement period includes: moving the SMTC window according to a preset offset within the next SMTC measurement period, and the preset offset is less than or equal to the length of the SMTC window.

[0007] Optionally, the STMC window has a starting position and an ending position, and moving the STMC window according to a preset offset includes: increasing or decreasing the starting position and the ending position of the SMTC window by the preset offset to obtain the position of the moved SMTC window.

[0008] Optionally, after moving the SMTC window to the position of the next SMTC measurement cycle, the step of: if the SMTC window is located in the Tth measurement cycle and the T+1th measurement cycle, then redetermining the position of the SMTC window in the T+2th measurement cycle, where T represents the next SMTC measurement cycle and is a positive integer greater than or equal to 1.

[0009] Optionally, the re-determining the position of the SMTC window in the N+2th measurement cycle includes: determining the original starting position and the original ending position of the SMTC window in the T+2th measurement cycle according to the starting position, the ending position and the preset offset of the SMTC window in the Tth measurement cycle;

[0010] The original starting position and the original ending position are modulo the length of the measurement period to obtain the final starting position and the final ending position of the SMTC window in the T+2th measurement period.

[0011] Optionally, the heterosystem neighbor cell search method also includes: if SSB is detected in the SMTC window in the Tth measurement cycle, determining that the position of the SMTC window in the measurement cycle after the Tth measurement cycle is the same as the position of the SMTC window in the Tth measurement cycle, which is a positive integer greater than or equal to 1.

[0012] Optionally, when SSB is not detected at least in the current measurement cycle, iteratively moving the SMTC window to the position of the next measurement cycle includes: when SSB is not detected in the current measurement cycle, iteratively moving the SMTC window to the position of the next measurement cycle; or, when SSB is not detected in the current measurement cycle and several consecutive measurement cycles before it, iteratively moving the SMTC window to the position of the next measurement cycle.

[0013] In a second aspect, an embodiment of the present invention provides a heterosystem neighbor cell search device, the device comprising: a detection module, used to detect SSB in the SMTC window in the current measurement cycle; a windowing module, used to iteratively move the position of the SMTC window in the next measurement cycle, and detect SSB in the SMTC window of the next measurement cycle at least when SSB is not detected in the SMTC window of the current measurement cycle, until SSB is detected in the SMTC window, and the position of the SMTC window after the movement is different from the position of the SMTC window before the movement; a reporting module, used to report information of the detected SSB.

[0014] In a third aspect, an embodiment of the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program executes the steps of the heterosystem neighbor area search method when executed by a processor.

[0015] In a fourth aspect, an embodiment of the present invention provides a terminal device, including a memory and a processor, wherein the memory stores a computer program that can be executed on the processor, and the processor executes the steps of the heterosystem neighbor area search method when running the computer program.

[0016] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0017] Since the transmission of the SMTC window and SSB is periodic, when the terminal device fails to detect the SSB in the SMTC window of the current measurement cycle, it means that the SSB is unlikely to be detected in the SMTC window of the subsequent measurement cycle. In the technical solution of the present invention, by moving the position of the SMTC window in the next measurement cycle, the SSB may fall within the SMTC window, and then by iteratively moving the SMTC window, the SSB can be detected in the SMTC window after a certain movement, thereby improving the success rate of neighbor search, communication efficiency and user experience.

[0018] Furthermore, the STMC window is moved according to a preset offset, and by setting the preset offset to be less than or equal to the length of the SMTC window, the STMC window moved multiple times can fully cover each time position within the detection period, thereby increasing the probability of successful SSB detection and further improving the success rate of neighboring area search.

[0024] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, long term evolution (LTE) systems, fifth generation (5G) systems, NR systems, and future evolution systems or multiple communication fusion systems.

The technical solution of the present application is also applicable to different network architectures, including but not limited to relay network architecture, dual link architecture, Vehicle-to-Everything (vehicle-to-anything communication) architecture and other architectures.

[0025] This application mainly relates to the communication between terminal equipment and network equipment. Among them:

[0026] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS) (also referred to as a base station device), which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, the equipment providing base station functions in the second generation (2nd-generation, 2G) network includes a base transceiver station (BTS), the equipment providing base station functions in the third generation (3rd-generation, 3G) network includes a node B (NodeB), the equipment providing base station functions in the fourth generation (4th-generation, 4G) network includes an evolved node B (evolved NodeB, eNB), in wireless local area networks (WLAN), the equipment providing base station functions is an access point (access point, AP), the equipment providing base station functions in NR is the next generation node base station (gNB), and the evolving node B (ng-eNB), wherein the gNB and the terminal device communicate using NR technology, and the ng-eNB and the terminal device communicate using Evolved Universal Terrestrial Radio Access (E-UTRA) technology, and both gNB and ng-eNB can be connected to the 5G core network. The network equipment in the embodiment of the present application also includes equipment that provides base station functions in future new communication systems, etc.

[0027] The terminal equipment in the embodiments of the present application may refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents or user devices. The terminal equipment may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolving Public Land Mobile Network (PLMN), etc., which is not limited in the embodiments of the present application. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0028] As described in the background technology, for NR and Long Term Evolution (LTE) multi-mode scenarios, due to the uncertainty of time alignment between LTE and NR systems, when the UE receives data according to the configured SMTC, it cannot be sure that there must be SSB in the SMTC window. The UE will not be able to search for neighboring cells according to the SMTC window configuration neighbor search, and will not be able to establish a secondary cell group (SCG) or initiate a handover from LTE to NR, affecting the user experience.

[0029] like Figure 1 As shown in the figure, the periods of the SMTC window and SSB are both 2 radio frames, that is, 20 milliseconds (ms). Due to the time misalignment between the LTE and NR systems, the SMTC window is at the head of a period and the SSB is in the middle of a period. If the UE detects SSB according to the current configuration of the SMTC window, it will not be able to search for neighboring cells.

[0030] In the technical solution of the present invention, by moving the position of the SMTC window in the next measurement cycle, the SSB is likely to fall within the SMTC window, and then by iteratively moving the SMTC window, the SSB can be detected in the SMTC window after a certain movement, thereby improving the success rate of neighboring area search, improving communication efficiency and user experience.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Figure 2 The present invention is a flowchart of a method for searching neighboring cells of a different system according to an embodiment of the present invention.

[0033] The heterogeneous system neighbor cell search method of the embodiment of the present invention can be used in a terminal device, that is, each step of the method can be executed by the terminal device, or by a chip in the terminal device.

[0034] Specifically, the heterosystem neighboring area search method may include the following steps:

[0035] In step 201, SSB is detected within the SMTC window in the current measurement cycle;

[0036] In step 202, at least when the SSB is not detected in the SMTC window of the current measurement cycle, iteratively move the position of the SMTC window in the next measurement cycle, and detect the SSB in the SMTC window of the next measurement cycle, until the SSB is detected in the SMTC window, and the position of the SMTC window after the movement is different from the position of the SMTC window before the movement;

[0037] In step 203, the detected SSB information is reported.

[0038] It should be pointed out that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0039] It is understandable that, in a specific implementation, the heterogeneous system neighbor cell search method can be implemented in the form of a software program, and the software program runs in a processor integrated inside a chip or a chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0040] The embodiments of the present invention can be applied to a scenario where a terminal device performs cell measurement between different communication systems, such as LTE and NR, or between various subsequent evolved communication systems.

[0041] In this embodiment, the measurement period refers to the period of the SMTC window, and each measurement period has an SMTC window. The terminal device can detect SSB within the SMTC window, and the terminal device does not need to detect SSB outside the SMTC window. The position of the SMTC window in the current measurement period can be pre-configured by the network device through high-level signaling, or it can be determined in the previous iteration process.

[0042] Specifically, the measurement period can be the same as the transmission period of the SSB, for example, it can be 5ms, 10ms, 20ms, 40ms, 80ms or 160ms. The SMTC window has a duration, which can be set according to the number of SSBs of the measured cell, for example, it can be 1ms, 2ms, 3ms, 4ms or 5ms.

[0043] In the specific implementation of step 202, when SSB is not detected in the SMTC window in one or more measurement cycles, the position of the SMTC window in the measurement cycle can be moved. The process of moving the position of the SMTC window in the measurement cycle is an iterative process, and the stopping condition of the iteration is that SSB is detected in the SMTC window.

[0044] Specifically, the position of the SMTC window in the measurement period is a relative position. For example, the position of the SMTC window before the movement is at the head of the measurement period, and the position of the SMTC window after the movement is in the middle of the measurement period.

[0045] In the specific implementation of step 203, the terminal device can obtain the information of the SSB in the SMTC window, and the information of the SSB can be the measurement period and time of the SSB. The terminal device can report the information of the SSB to a network device, such as a base station or a core network.

[0046] In a non-limiting embodiment, the STMC window is moved according to a preset offset in the next SMTC measurement cycle, and the preset offset is less than or equal to the length of the SMTC window.

[0047] In an embodiment of the present invention, by setting a preset offset less than or equal to the length of the SMTC window, the STMC window moved multiple times can fully cover each time position within the detection period, thereby increasing the probability of successful SSB detection and further improving the success rate of neighboring area search.

[0048] For example, see Figure 3 , the measurement cycle is two radio frames of 20ms. In the measurement cycle of radio frame N and radio frame N+1, the terminal device did not detect SSB in the SMTC window. Then in the measurement cycle of radio frame N+2 and radio frame N+3, the position of the SMTC window can be moved, and the terminal device still did not detect SSB in the SMTC window. In the measurement cycle of radio frame N+4 and radio frame N+5, the position of the SMTC window can continue to be moved. The terminal device detects SSB in the SMTC window, so stop moving the SMTC window. In the measurement cycle of radio frame N+6 and radio frame N+7, the position of the SMTC window is the same as its position in the previous measurement cycle.

[0049] Furthermore, the STMC window has a starting position and an ending position, and the starting position and the ending position of the SMTC window are increased or decreased by the preset offset to obtain the position of the moved SMTC window.

[0050] Specifically, Figure 3 For example, increasing the preset offset of the starting position and the ending position means moving the SMTC window to the right, and decreasing the preset offset of the starting position and the ending position means moving the SMTC window to the left.

[0051] In a non-limiting embodiment, if the SMTC window is located in the Tth measurement cycle and the T+1th measurement cycle, the position of the SMTC window is re-determined in the T+2th measurement cycle, where T represents the next SMTC measurement cycle and T is a positive integer greater than or equal to 1.

[0052] In this embodiment, the SMTC window is located in the Tth measurement cycle and the T+1th measurement cycle, which means that the SMTC window spans two measurement cycles. In this case, in order to ensure the accuracy of the measurement, the position of the SMTC window can be re-determined in the next measurement cycle after the two measurement cycles, that is, the T+2th measurement cycle.

[0053] Specifically, the re-determined position of the SMTC window may be the initial position of the SMTC window configured by the high-layer signaling.

[0054] Furthermore, the position of the SMTC window can also be re-determined in the following manner: determine the original starting position and original ending position of the SMTC window in the T+2 measurement cycle based on the starting position, ending position and preset offset of the SMTC window in the Tth measurement cycle; take the modulo of the original starting position and original ending position with the length of the measurement cycle to obtain the final starting position and final ending position of the SMTC window in the T+2 measurement cycle.

[0055] Please refer to Figure 4, in the measurement cycle of radio frame N+2 and radio frame N+3, the SMTC window is located at 4-9ms, and the terminal device does not detect SSB in the SMTC window. In the measurement cycle of radio frame N+4 and radio frame N+5, the position of the SMTC window can be moved to 8-13ms, and the terminal device does not detect SSB in the SMTC window. In the measurement cycle of radio frame N+6 and radio frame N+7, the position of the SMTC window is continued to be moved to 12-17ms, and the terminal device does not detect SSB in the SMTC window. In the measurement cycle of radio frame N+8 and radio frame N+9, the position of the SMTC window is continued to be moved to 16-21ms, and the terminal device does not detect SSB in the SMTC window. Since the SMTC window spans two measurement cycles at this time, the range of 20-25 can be modulo 20 to determine the position in the SMTC window as 0-5ms in the measurement cycle of radio frame N+12 and radio frame N+13.

[0056] In the embodiment of the present invention, the position of the SMTC window after the movement partially overlaps with the position of the SMTC window before the movement, for example, 0-5ms and 4-9ms overlap by 1ms in time. The reason for this setting is that the detection effect of the terminal device at the boundary position of the SMTC window is poor. Through the above method, the SSB detection of the terminal device at the overlapping position can be made more accurate, thereby improving the success rate of SSB detection.

[0057] In a non-limiting embodiment, when no SSB is detected in a single measurement cycle, the position of the SMTC window in the next measurement cycle is iteratively moved.

[0058] Alternatively, when no SSB is detected in the current measurement cycle and several consecutive measurement cycles before the current measurement cycle, the SMTC window is iteratively moved to the position of the next measurement cycle.

[0059] By setting the operation of triggering the movement of the SMTC window only when SSB is not detected in several measurement cycles, the robustness of SSB detection can be guaranteed, and unnecessary power consumption caused by the terminal misdetecting SSB and triggering window movement can be avoided.

[0060] Please refer to Figure 5 The embodiment of the present invention further discloses a heterogeneous system neighboring area search device. The heterogeneous system neighboring area search device 50 may include:

[0061] A detection module 501, configured to detect SSB within the SMTC window in the current measurement cycle;

[0063] The reporting module 503 is used to report the detected SSB information.

[0064] The embodiment of the present invention performs neighbor cell search by moving the SMTC window, so that the terminal device can still try to discover and search for neighbor cells in different existing network or private network scenarios when SSB cannot be detected in the SMTC window, thereby increasing the neighbor cell search capability and scenario compatibility of the device.
