Best Mode for Carrying Out the Invention

[0017] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings refer to the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present application detailed in the appended claims.

[0018] FIG. 1 shows a block diagram of a communication system provided by an exemplary embodiment of the present disclosure. The communication system can include an access network 12 and a user terminal 14.

[0019] The access network 12 includes several network devices 120. These network devices (also called access network devices) 120 may be base stations, which are configured on the access network to provide wireless communication functionality to user terminals (also simply called "terminals") 14. Base stations can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with base station functionality may differ. For example, in Long Term Evolution (LTE) systems, they are called eNodeB or eNB, and in 5G NR (New Radio) systems, they are called gNodeB or gNB. As communication technology evolves, the term "base station" may also change. In the embodiments of this disclosure, for convenience of explanation, the above-mentioned devices that provide wireless communication functionality to user terminals 14 are collectively referred to as network devices.

[0020] The user terminal 14 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user devices, mobile stations (MS), terminal devices, etc. For convenience of explanation, the above devices are collectively referred to as user terminals. The network device 120 and the user terminal 14 communicate with each other through some air interface technology, such as a Uu interface.

[0021] Exemplary, one cell may be associated with one base station, or multiple cells (i.e., at least two cells) may be associated with one base station. Between adjacent cells, there is an overlapping area covered by the beam, and within this overlapping area, the user terminal 14 can switch between cells.

[0022] For example, when a user terminal 14 accesses one cell, in the process of switching from that cell to an adjacent cell, the user terminal 14 first performs the adjacent cell measurement method provided in the embodiment of the present invention to perform beam measurement of the adjacent cell, and then performs dynamic switching between cells based on the beam measurement results.

[0023] The technical examples of the embodiments described herein include Global System of Mobile Communication (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS), Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Advanced Long Term Evolution (LTE-A) systems, New Radio (NR) systems, NR system evolution systems, Unlicensed Frequency Band LTE (LTE-based access to Unlicensed spectrum, LTE-U) systems, NR-U systems, Universal Mobile Telecommunication System (UMTS), and Worldwide Interoperability for Microwave Access. It can be applied to various communication systems, including Access (WiMAX), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication systems, and other communication systems.

[0024] Generally, conventional communication systems support a limited number of connections, making them relatively easy to implement. However, with advancements in communication technology, mobile communication systems will not only support conventional communication but also device-to-device (D2D), machine-to-machine (M2M), machine-type communication (MTC), vehicle-to-vehicle (V2V), and vehicle-to-everything (V2X) systems. The embodiments of this disclosure are also applicable to these communication systems.

[0025] Figure 2 shows a flowchart of a method for measuring adjacent cells provided by an exemplary embodiment of the present disclosure. The method is applied to a terminal of a communication system shown in Figure 1. The method includes the following steps 210 and 220.

[0026] In step 210, the setting information for the first measurement window is received, and the first measurement window is used to perform beam measurements based on the reference signal of the adjacent cell.

[0027] The terminal receives configuration information for a first measurement window (MW) transmitted from a network device over a Physical Downlink Shared Channel (PDSCH), and this configuration information is used to set the first configuration parameter of the first measurement window for the terminal. For example, the terminal receives configuration information for a first measurement window transmitted by a network device via Radio Resource Control (RRC) signaling.

[0028] Selectively, the setting information for the first measurement window is The first length of the first measurement window, The first period of the first measurement window, The first offset value of the first measurement window, and It includes at least one of the first setting parameters, namely the first timing advance (TA) of the first measurement window.

[0029] The length of the first measurement window described above refers to the length of the symbols occupied by the first measurement window in the time domain. The period of the first measurement window refers to the time interval between the start times (or end times) of each adjacent pair of first measurement windows. The offset value of the first measurement window refers to the offset value of the first measurement window relative to the start point in the time domain; that is, the time domain position of the first measurement window is the position of the start point plus the offset value of the first measurement window. Here, the start point is a TA millisecond before the subframe immediately preceding the setting information of the first measurement window.

[0030] Selectively, the reference signal of an adjacent cell includes at least one of the following: a synchronization signal block (SS / PBCH Block, SSB) and channel state information reference signals (CSI-RS).

[0031] Selectively, the first length of the first measurement window described above is determined by the duration of the adjacent cell's reference signal and the terminal's radio frequency retuning (RF retuning) time. As shown in Figure 3, an example of an adjacent cell measurement window is shown, illustrating the time-domain positional relationship between the first measurement window and the non-serving cell reference signals and radio frequency retuning time, where the non-serving cell is the adjacent cell.

[0032] Selectively, the first length of the first measurement window is greater than or equal to the sum of the duration of the adjacent cell's reference signal and twice the terminal's radio frequency retuning time. Exemplarily, as shown in Figure 3, the first length of the first measurement window includes the duration of the adjacent cell's reference signal and two radio frequency retuning times, where the two radio frequency retuning times are located before the start time and after the end time of the adjacent cell's reference signal, respectively.

[0033] In step 220, the reference signal of the adjacent cell is measured based on the first measurement window, and the beam measurement result of the adjacent cell is obtained.

[0034] For example, the terminal determines a first measurement window based on configuration information, measures the reference signal of an adjacent cell within the first measurement window, and obtains the beam measurement result of the adjacent cell.

[0035] The terminal periodically measures the reference signal of the adjacent cell based on a first measurement window. Selectively, the first period of the first measurement window is either different from or the same as the period of the reference signal of the adjacent cell. Exemplarily, as shown in Figure 3, both the first period of the first measurement window and the period of the reference signal of the adjacent cell are D1.

[0036] Selectively, if the first period of the first measurement window differs from the period of the reference signal of the adjacent cell, the first period of the first measurement window is an integer multiple of the period of the reference signal of the adjacent cell. Exemplarily, as shown in Figure 4, the first period D2 of the first measurement window is twice the period D1 of the reference signal of the adjacent cell.

[0037] For example, after obtaining beam measurement results from an adjacent cell, the terminal reports these beam measurement results to a network device, which then decides whether or not to switch the terminal's serving cell based on these beam measurement results.

[0038] In summary, the adjacent cell measurement method provided by this embodiment involves a terminal receiving setting information for a first measurement window, determining the first measurement window, and then measuring the reference signal of the adjacent cell based on the first measurement window to obtain the beam measurement result of the adjacent cell. This method is used in L1 / L2 based inter-cell mobility to support the terminal in achieving dynamic switching between cells based on the beam measurement results of adjacent cells. Network devices can obtain the beam measurement results of adjacent cells in real time, enable the terminal to switch serving cells via dynamic signaling, and reduce latency overhead due to mobility issues.

[0039] The serving cell of a terminal and its neighboring cells may use the same frequency or they may use different frequencies. For example, as shown in Figure 5, if the serving cell of a terminal and its neighboring cells use the same frequency, step 220 above can be achieved by step 322, which is shown below.

[0040] In step 322, if the serving cell and the adjacent cell use the same frequency and the reference signal of the adjacent cell is included in the activated Bandwidth Part (BWP) of the terminal, the reference signal of the adjacent cell is measured in a second measurement window to obtain the beam measurement result of the adjacent cell, the second measurement window is obtained by subtracting the terminal's radio frequency retuning time from the first measurement window, or the second measurement window is determined based on the duration of the adjacent cell's reference signal.

[0041] The serving cell and adjacent cells may be different cells corresponding to the same network device, or they may be different cells corresponding to different network devices.

[0042] To determine the second measurement window, the terminal subtracts twice the terminal's radio frequency retuning time from the first measurement window to obtain the second measurement window. Alternatively, the terminal may determine a second measurement window based on the duration of the reference signal of an adjacent cell. For example, the terminal may determine the duration of the reference signal of an adjacent cell as the time length of the second measurement window, and then determine the second measurement window based on the time length of the second measurement window.

[0043] For example, as shown in Figure 6, if the serving cell of a terminal and its neighboring cells use the same frequency, step 220 above may be implemented by step 324. The step is shown below.

[0044] In step 324, if the serving cell and the adjacent cell use the same frequency and the reference signal of the adjacent cell is included in the activated BWP of the terminal, the reference signal of the adjacent cell is measured within the first measurement window to obtain the beam measurement result of the adjacent cell.

[0045] Steps 322 and 324 are interchangeable. Compared to the measurement method in step 324, the measurement window length measured by the measurement method in step 322 is shorter, thus requiring fewer measurement resources.

[0046] For example, as shown in Figure 7, if the serving cell and adjacent cells of a terminal use the same or different frequencies, step 220 above can be accomplished by steps 422 to 424 below. The steps are shown below.

[0047] In step 422, if the reference signal of the adjacent cell satisfies the first condition, the reference signal of the adjacent cell is measured within the first measurement window to obtain the beam measurement result of the adjacent cell.

[0048] For example, the first condition described above may be pre-configured for the terminal by a network device, or the first condition described above may be pre-defined by a protocol.

[0049] If the reference signal of an adjacent cell satisfies the first condition, the terminal determines the first measurement window based on the setting information of the first measurement window and measures the reference signal of the adjacent cell within the first measurement window.

[0050] Selectively, the first condition is, Using different frequencies for the serving cell and adjacent cells, or This includes one of the following: the serving cell and the adjacent cell use the same frequency, and the reference signal of the adjacent cell is not entirely included in the activated BWP of the terminal.

[0051] For example, if the terminal's serving cell uses a different frequency than the adjacent cell, it measures the reference signal of the adjacent cell within the first measurement window. Alternatively, if the terminal's serving cell uses the same frequency as the adjacent cell, and the adjacent cell's reference signal is not entirely included in the terminal's activated BWP, it measures the reference signal of the adjacent cell within the first measurement window.

[0052] In step 424, if the reference signal does not satisfy the first condition, the reference signal of the adjacent cell is measured at the time-frequency position of the reference signal of the adjacent cell to obtain the beam measurement result of the adjacent cell.

[0053] For example, if the terminal determines that the serving cell and the adjacent cell use the same frequency and that the adjacent cell's reference signal is fully contained within the terminal's activated BWP, it will measure the adjacent cell's reference signal at the time-frequency position of the adjacent cell's reference signal to obtain the beam measurement result for the adjacent cell.

[0054] In other words, if the reference signal does not satisfy the first condition, measurement is performed directly at the time-frequency position of the reference signal in the adjacent cell. This reduces protocol changes and the occupation of computing resources because the terminal does not need to calculate the measurement window.

[0055] In summary, the neighboring cell measurement method provided by this embodiment considers both cases where the terminal's serving cell and neighboring cell use the same frequency and cases where they use different frequencies, thus resolving channel / signal contention issues between the terminal's serving cell and neighboring cells, as well as potential radio frequency retuning time issues. Furthermore, the terminal does not need to receive data from the serving cell within the measurement window.

[0056] In some embodiments, the terminal may also update the first measurement window while measuring adjacent cells. Exemplarily, the step of updating the first measurement window, as shown in Figure 8, is described below.

[0057] In step 510, the first update information for the first measurement window is received. The terminal receives first update information transmitted from the network device. Selectively, the first update information is included in the Media Access Control Layer (MAC Control Element, MAC CE) signaling. The full name of MAC is Medium Access Control. In other words, the terminal receives first update information transmitted by the network device via MAC CE signaling.

[0058] Selectively, the first update information includes at least the measurement setting identifier (IDentification, ID) associated with the adjacent cell and a second setting parameter for the first measurement window.

[0059] For example, the second setting parameter of the first measurement window includes the second period of the first measurement window.

[0060] Selectively, the second setting parameter is: The second length of the first measurement window, The second offset value of the first measurement window, and This includes at least one of the following: the second timing advance of the first measurement window.

[0061] In the embodiments of this application, the updating of the setting parameters of the first measurement window will be explained using the updating of the period of the first measurement window as an example. Exemplarily, the second period of the first measurement window is either the same as or different from the period of the reference signal of the adjacent cell. If the second period of the first measurement window is different from the period of the reference signal of the adjacent cell, the second period of the first measurement window is an integer multiple of the period of the reference signal of the adjacent cell.

[0062] In step 520, the setting parameters of the first measurement window are updated based on the first update information. The terminal updates the configuration parameters of the first measurement window based on the first update information, obtains the updated first measurement window, then measures the reference signal of the adjacent cell based on the updated first measurement window to obtain the beam measurement result of the adjacent cell, and reports the beam measurement result of the adjacent cell to the network device. Exemplaryly, the terminal updates the first period of the first measurement window to the second period and obtains the updated first measurement window.

[0063] In summary, the adjacent cell measurement method provided by this embodiment updates the period of a first measurement window based on first update information set by a network device, adjusts the beam measurement period of the adjacent cell and the reporting period of the beam measurement results according to the dynamically changing movement speed of the terminal, and supports beam measurement of adjacent cells by the terminal at different movement speeds. For example, if the terminal's movement speed is high, the measurement window period is updated to a smaller value, and if the terminal's movement speed is low, the measurement window period is updated to a larger value.

[0064] In another embodiment, the reference signal of an adjacent cell can be updated while the adjacent cell is being measured. Exemplarily, the step of updating the reference signal of an adjacent cell, as shown in Figure 9, is described below.

[0065] In step 610, the second update information for the reference signal is received. The terminal receives a second update from a network device. Selectively, the second update is included in the RRC signaling. Exemplarily, the terminal receives a second update transmitted by a network device via the RRC signaling.

[0066] In step 620, the setting parameters for the reference signal of the adjacent cell are updated based on the second update information. Before the update, the setting parameters for the adjacent cell's reference signal included a first time-frequency resource for the adjacent cell's reference signal and first measurement window information corresponding to the adjacent cell's reference signal, with the time-domain period corresponding to the first time-frequency resource matching the terminal's movement speed.

[0067] For example, the second update information includes a second time-frequency resource of the reference signal from an adjacent cell, and since the time-domain period corresponding to the second time-frequency resource matches the terminal's moving speed, the user can obtain beam measurement results in real time.

[0068] For example, the second update information further includes second measurement window information corresponding to the reference signal of an adjacent cell, such that the period of the terminal's first measurement window is the same as the period of the reference signal of the adjacent cell, or the period of the first measurement window is an integer multiple of the period of the reference signal of the adjacent cell.

[0069] The terminal updates the first time-frequency resource of the adjacent cell's reference signal to the second time-frequency resource, and updates the first measurement window information of the adjacent cell's reference signal to the second measurement window information.

[0070] In summary, the adjacent cell measurement method provided by this embodiment supports beam measurement of adjacent cells when the reference signal of the adjacent cell changes dynamically. For example, if the initial period of the adjacent cell measurement reference signal is large and measurement results cannot be obtained in real time when the user speed is too fast, the measurement settings can be updated via RRC signaling.

[0071] Figure 10 shows a flowchart of a method for measuring adjacent cells provided by an exemplary embodiment of the present disclosure. The method is applied to a network device of a communication system shown in Figure 1 and includes the following steps 710 and 720.

[0072] In step 710, setting information for the first measurement window is transmitted, and the first measurement window is used to perform beam measurements based on the reference signal of the adjacent cell. The network device sets the configuration information for the first measurement window on the terminal and sends the configuration information for the first measurement window to the terminal.

[0073] Selectively, the setting information for the first measurement window described above is: The first length of the first measurement window, The first period of the first measurement window, The first offset value of the first measurement window, and It includes at least one of the first setting parameters, which is the first timing advance of the first measurement window.

[0074] Selectively, the first length of the first measurement window is determined by the duration of the reference signal of the adjacent cell and the radio frequency retuning time of the terminal. Exemplarily, a network device determines the first length of the first measurement window based on the duration of the reference signal of the adjacent cell and the radio frequency retuning time of the terminal.

[0075] Selectively, the first length of the first measurement window is greater than or equal to the sum of the duration of the adjacent cell's reference signal and twice the terminal's radio frequency retuning time. Exemplarily, a network device determines that the first length of the first measurement window is greater than or equal to the sum of the duration of the adjacent cell's reference signal and twice the terminal's radio frequency retuning time.

[0076] Selectively, the first period of the first measurement window is either different from or the same as the period of the reference signal of the adjacent cell. Exemplarily, the network device determines that the first period of the first measurement window is the same as the period of the reference signal of the adjacent cell.

[0077] Selectively, if the first period of the first measurement window differs from the period of the reference signal of the adjacent cell, then the first period of the first measurement window is an integer multiple of the period of the reference signal of the adjacent cell. Exemplaryly, a network device determines that the first period of the first measurement window is G times the period of the reference signal of the adjacent cell, and that the value of G is an integer greater than 1.

[0078] In step 720, the terminal receives the beam measurement results of the adjacent cell, which were measured based on the reference signal of the adjacent cell.

[0079] In summary, the adjacent cell measurement method provided by this embodiment involves a network device setting configuration parameters for a first measurement window for a terminal, and L1 / L2 based inter-cell mobility supports beam measurement of adjacent cells by the terminal and dynamic switching between cells by the terminal.

[0080] In some embodiments, during measurement of adjacent cells, the network device sets first update information for the first measurement window for the terminal. As shown in Figure 11, the steps are as follows:

[0081] In step 810, first update information for the first measurement window is sent to the terminal, and the first update information is used to update the setting parameters of the first measurement window in the terminal.

[0082] Selectively, the first update information is included in the MAC CE signaling. That is, the network device sends the first update information to the terminal via MAC CE signaling.

[0083] Selectively, the first update information includes at least the measurement setting ID associated with the adjacent cell and the second setting parameter of the first measurement window.

[0084] For example, the second setting parameter of the first measurement window includes the second period of the first measurement window.

[0085] Selectively, the second setting parameter of the first measurement window is: The second length of the first measurement window, The second offset value of the first measurement window, and It may further include at least one of the second timing advances of the first measurement window.

[0086] Selectively, the beam measurement results include a Resource Indicator (RI) index of the reference signal corresponding to the optimal beam, in which case the network device calculates the beam rate of change based on the Reference Indicator index of the optimal beam, and if the beam rate of change changes, determines the first update information for the first measurement window based on the correspondence, the correspondence includes the correspondence between the beam rate of change and the setting parameters of the first measurement window.

[0087] As an example, Figure 12 shows the correspondence between the beam change rate and the period of the first measurement window. For example, if the beam change rate is greater than 0 and less than or equal to BCR0, the period of the first measurement window is T0, and if the beam change rate is greater than BCR0 and less than or equal to BCR1, the period of the first measurement window is T1. Alternatively, if the beam change rate is greater than or equal to 0 and less than BCR0, the period of the first measurement window is T0, and if the beam change rate is greater than or equal to BCR0 and less than BCR1, the period of the first measurement window is T1.

[0088] Selectively, for Beam Change Rate (BCR), the network device uses the first index RI. i and the second index RI i-1 The difference value is calculated, the first index is the index of the reference signal corresponding to the optimal beam reported in the i-th measurement, and the second index is the index of the reference signal corresponding to the optimal beam reported in the (i-1)th measurement, where i is a positive integer greater than 1, and T is the ratio of the difference value to the period of the first measurement window. i Calculate the beam change rate BCR i Obtain it.

[0089] For example, the formula for calculating the beam change rate is shown below.

number

[0090] For example, when the setting parameters of the first measurement window are updated, if the period of the first measurement window is the first period, then the setting parameters in the calculation process described above are the second period.

[0091] In summary, the adjacent cell measurement method provided by this embodiment involves a network device setting first update information to a terminal to update the period of the first measurement window, adjusting the beam measurement period of the adjacent cell and the reporting period of the beam measurement results according to the dynamically changing travel speed of the terminal, thereby supporting beam measurement of adjacent cells by terminals at different travel speeds.

[0092] In some embodiments, while measuring an adjacent cell, the network device sets a second update of the adjacent cell's reference signal for the terminal. As shown in Figure 13, the steps are as follows:

[0093] In step 910, a second update of the reference signal of the adjacent cell is sent to the terminal, and the second update is used to update the setting parameters of the reference signal of the adjacent cell.

[0094] Selectively, the second update information is included in the RRC signaling. Exemplaryly, a network device transmits the second update information of the reference signal of an adjacent cell to a terminal via RRC signaling.

[0095] Before the update, the setting parameters for the adjacent cell's reference signal included a first time-frequency resource for the adjacent cell's reference signal and first measurement window information corresponding to the adjacent cell's reference signal, with the time-domain period corresponding to the first time-frequency resource matching the terminal's movement speed.

[0096] For example, the second update information includes a second time-frequency resource of the reference signal from an adjacent cell, and since the time-domain period corresponding to the second time-frequency resource matches the terminal's moving speed, the user can obtain beam measurement results in real time.

[0097] For example, the second update information further includes second measurement window information corresponding to the reference signal of an adjacent cell, such that the period of the terminal's first measurement window is the same as the period of the reference signal of the adjacent cell, or the period of the first measurement window is an integer multiple of the period of the reference signal of the adjacent cell.
