Description

[0001] This application is a divisional application. The original application has the application number 202080105844.6 and the original application date is October 23, 2020. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a method, apparatus and system for measuring re-synchronization signal (RSS). Background Technology

[0003] Radio resource management (RRM) measurements refer to measurements performed by terminal equipment to assist mobility management (such as handover or reselection of terminal equipment). RRM measurements may include reference signal received power (RSRP) measurements. In enhanced machine-type communication (eMTC), terminal equipment can perform RSRP measurements of a cell by measuring the cell's RSS.

[0004] However, in some cases, such as when the serving cell and neighboring cells are asynchronous, the terminal device cannot measure the RSS of the neighboring cell, which makes it impossible to measure the RSRP of the neighboring cell by measuring its RSS, thus reducing the reliability of communication. Summary of the Invention

[0005] This application provides a method, apparatus, and system for measuring RSS, which solves the problem that terminal devices cannot measure the RSS of neighboring cells.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] In a first aspect, this application provides a method for measuring RSS. A terminal device determines a time-domain location, which is the time-domain location of the neighboring cell's RSS within the timing of that neighboring cell, and determines a first sequence parameter of the neighboring cell's RSS. Then, the terminal device measures the neighboring cell's RSS based on the time-domain location and the first sequence parameter of the neighboring cell's RSS.

[0008] In this way, the terminal device can determine the time-domain position of the neighboring cell's RSS within the timing of that neighboring cell, as well as the first sequence parameters of the neighboring cell's RSS. Based on the time-domain position and the first sequence parameters of the neighboring cell's RSS, it can measure the neighboring cell's RSS, solving the problem of the terminal device being unable to measure the neighboring cell's RSS, especially when the serving cell and the neighboring cell are asynchronous. Accurate measurement of the neighboring cell's RSS makes it possible to further measure the neighboring cell's RSRP, thus providing a foundation for the terminal device to subsequently perform cell reselection or measurement reporting.

[0009] Optionally, in one possible implementation of this application, the time-domain location includes at least one of the following: the frame in which the neighboring cell's RSS is located, and the subframe in which the neighboring cell's RSS is located.

[0010] Optionally, in another possible implementation of this application, the method for "determining time-domain location" may include: the terminal device receiving first RSS configuration information about neighboring cells in the serving cell, the first RSS configuration information carrying first information for indicating time-domain location, and the terminal device determining the time-domain location based on the first information. Alternatively, the terminal device determines the time-domain location based on a first preset rule.

[0011] Thus, the terminal device can determine the time domain location using either of the two methods described above. Alternatively, the terminal device can first determine whether the time domain location can be determined based on the first RSS configuration information. If it can, the time domain location is directly determined based on the first RSS configuration information. If it cannot, the terminal device determines the time domain location according to the first preset rule.

[0012] Terminal devices can determine the frame or subframe in which the RSS of a neighboring cell is located during the timing of that neighboring cell through network device configuration or a first preset rule. The method of determining the frame or subframe in which the RSS of a neighboring cell is located through network device configuration allows each cell to configure different time-domain locations for its RSS, increasing network flexibility. The method of determining the frame or subframe in which the RSS of a neighboring cell is located through a first preset rule can determine the frame or subframe in which the RSS of a neighboring cell is located during the timing of that neighboring cell without adding extra signaling, effectively saving system resources.

[0013] Optionally, in another possible implementation of this application, the first information includes information indicating the target frame of the neighboring cell's RSS within the timing of the neighboring cell and overlapping with the first frame. If the first frame is the frame of the neighboring cell's RSS within the timing of the serving cell, the aforementioned method of "determining the time-domain location based on the first information" may include: the terminal device determining that the frame containing the neighboring cell's RSS is the target frame. Since the timing of the neighboring cell may differ from that of the serving cell, the number of frames overlapping with the first frame within the timing of the neighboring cell's RSS may be more than one. For example, there may be two frames overlapping with the first frame. In this case, the first information is used to indicate which of these two frames is the target frame.

[0014] Optionally, in another possible implementation of this application, if the first information includes information for indicating the configuration of bandwidth-limited / coverage-enhanced (BL / CE) subframes of neighboring cells, the above-mentioned method of "determining the temporal location based on the first information" may include: the terminal device determining that the subframe in which the RSS of the neighboring cell is located is a BL / CE subframe within the frame in which the RSS of the neighboring cell is located.

[0015] Optionally, in another possible implementation of this application, the first information includes information for indicating the target frame of the neighboring cell's RSS in the timing of the neighboring cell and in the frame overlapping with the first frame, and information for indicating the configuration of the neighboring cell's BL / CE subframe. If the first frame is the frame of the neighboring cell's RSS in the timing of the serving cell, the above-mentioned method of "determining the time domain location based on the first information" may include: the terminal device determining that the frame where the neighboring cell's RSS is located is the target frame, and determining that the subframe where the neighboring cell's RSS is located is the BL / CE subframe within the target frame.

[0016] Optionally, in another possible implementation of this application, if the time-domain location includes the frame where the RSS of the neighboring cell is located, the above-mentioned method of "determining the time-domain location according to the first preset rule" may include: the terminal device determines the frame in the timing of the neighboring cell that is closest to the first frame as the frame where the RSS of the neighboring cell is located, wherein the first frame is determined according to the second RSS configuration information about the neighboring cell.

[0017] Optionally, in another possible implementation of this application, if the time-domain location includes the subframe where the RSS of the neighboring cell is located, the above-mentioned method of "determining the time-domain location according to the first preset rule" may include: the terminal device determining the BL / CE subframe within the frame where the RSS of the neighboring cell is located, which has the same configuration as the BL / CE subframe of the serving cell, as the subframe where the RSS of the neighboring cell is located.

[0018] Optionally, in another possible implementation of this application, where the time-domain location includes the frame containing the neighboring cell's RSS and the subframe containing the neighboring cell's RSS, the above-mentioned method of "determining the time-domain location according to the first preset rule" may include: the terminal device determining the frame in the timing of the neighboring cell that is closest to the first frame as the frame containing the neighboring cell's RSS, wherein the first frame is determined according to the second RSS configuration information about the neighboring cell; and determining the BL / CE subframe within the frame containing the neighboring cell's RSS, which has the same configuration as the BL / CE subframe of the serving cell, as the subframe containing the neighboring cell's RSS.

[0019] Optionally, in another possible implementation of this application, the method for "determining the first sequence parameters of the neighboring cell's RSS" may include: the terminal device receiving third RSS configuration information about the neighboring cell in the serving cell, the third RSS configuration information carrying second information for indicating the first sequence parameters of the neighboring cell's RSS; and determining the first sequence parameters of the neighboring cell's RSS based on the second information. Alternatively, the terminal device determines the first sequence parameters of the neighboring cell's RSS according to a second preset rule.

[0020] The terminal device can determine the first sequence parameters of the RSS of neighboring cells through network device configuration or a second preset rule. The method of determining the first sequence parameters of the RSS of neighboring cells through network device configuration ensures that the terminal device can still correctly measure the RSS of neighboring cells even when different cells have different first sequence parameters. The method of determining the first sequence parameters of the RSS of neighboring cells through the second preset rule allows the value of the first sequence parameters to be determined without adding extra signaling.

[0021] Optionally, in another possible implementation of this application, the method of "determining the first sequence parameter of the RSS of the neighboring cell according to the second preset rule" may include: the terminal device determining the first sequence parameter of the RSS of the serving cell as the first sequence parameter of the RSS of the neighboring cell.

[0022] Optionally, in another possible implementation of this application, the RSS measurement method provided by this application may further include: the terminal device obtaining the first reference signal receiving power (RSRP) of the neighboring cell based on the measurement result of the RSS of the neighboring cell; and the terminal device measuring the RSS of the serving cell and obtaining the second RSRP of the serving cell based on the measurement result of the RSS of the serving cell. Then, the terminal device performs cell reselection or measurement reporting based on the first RSRP and the second RSRP.

[0023] A terminal can obtain the cell's RSRP and reference signal received quality (RSRQ) by measuring the cell's CRS. Based on the RSRP and RSRQ of neighboring cells and the serving cell, the terminal can then perform cell reselection or measurement reporting. Under certain conditions, cell measurements can be performed based on RSS. In this case, cell reselection or measurement reporting can be performed solely based on RSRP, and measuring RSRP based on RSS is more effective than measuring RSRP based on CRS.

[0024] Optionally, in another possible implementation of this application, the RSS measurement method provided by this application may further include: the terminal device performing a modulo operation on the period of the neighboring cell's RSS using a target value, and determining the result of the modulo operation as the frame number of the first frame. Here, the target value is determined based on the second RSS configuration information about the neighboring cell received in the serving cell, and the first frame is the frame of the neighboring cell's RSS within the timing of the serving cell. By performing the modulo operation, the range of the calculated frame number is effectively avoided from exceeding the range of the neighboring cell's RSS period.

[0025] Secondly, this application provides an RSS measuring device, which includes various modules for performing the RSS measuring method of the first aspect or any possible implementation thereof.

[0031] In a seventh aspect, this application provides a method for measuring RSS, wherein a network device determines first RSS configuration information about a neighboring cell and sends the first RSS configuration information. The first RSS configuration information carries first information. The first information is used to indicate the time-domain position of the determined neighboring cell's RSS within the neighboring cell's timing.

[0032] In this way, by sending the first RSS configuration information to the terminal device through the network device, the terminal device can determine the frame or subframe where the RSS of the neighboring cell is located according to the configuration of the network device. This allows each cell to configure different time-domain locations for the RSS, increasing network flexibility.

[0033] Optionally, in one possible implementation of this application, the time-domain location includes at least one of the following: the frame in which the neighboring cell's RSS is located, and the subframe in which the neighboring cell's RSS is located.

Here, the first frame is the frame of the neighboring cell's RSS in the timing of the serving cell.

The third RSS configuration information carries second information; the second information is used to indicate the first sequence parameters for determining the RSS of neighboring cells.

[0038] In this way, by sending third RSS configuration information to the terminal device through the network device, so that the terminal device can determine the first sequence parameters of the RSS of the neighboring cell through the configuration of the network device, it is ensured that the terminal device can still correctly measure the RSS of the neighboring cell even when different RSS first sequence parameters are configured in each cell.

[0055] In the embodiments of this application, the word "for example" is used to indicate that something is being described as an example, illustration, or description. Any embodiment or design that is described as "for example" in the embodiments of this application should not be construed as being better or more advantageous than other embodiments or design. Rather, the use of the word "for example" is intended to present the relevant concepts in a specific manner.

[0056] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this application, unless otherwise stated, "a plurality of" means two or more.

[0057] One method for measuring the RSRP of a neighboring cell is based on measuring the cell reference signal (CRS) of the neighboring cell. When a terminal device measures the CRS of a neighboring cell, it first needs to determine the time-domain location of the CRS. The CRS of a neighboring cell is transmitted in each subframe, therefore the terminal device can measure the CRS of the neighboring cell in any subframe of the neighboring cell's transmission resources.

[0058] With the rapid development of communication technology, RSRP measurement based on RSS has been introduced in eMTC of long-term evolution (LTE) systems. Measuring RSRP by measuring the RSS of neighboring cells has the advantages of shorter measurement cycle and higher measurement accuracy compared to measuring RSRP by measuring the CRS of neighboring cells.

[0059] When a terminal device measures the RSS of a neighboring cell, it first needs to determine the time domain location of the neighboring cell's RSS. Since RSS occurs periodically, the terminal device needs to determine the period of the neighboring cell's RSS and the time domain location of the first occurrence of the neighboring cell's RSS. This allows it to obtain the time domain location of the RSS of all periodically occurring neighboring cells. Finally, by measuring the RSS of neighboring cells over multiple periods, the RSRP of that neighboring cell can be obtained.

[0060] However, in the case of asynchronous cell operation (the timing of neighboring cells is different from that of the serving cell), there is a problem that the terminal device cannot determine the time domain position of the neighboring cell's RSS based on the timing of that neighboring cell, thus making it impossible to measure the RSS of the neighboring cell.

[0061] In addition, because the terminal device cannot obtain the first sequence parameter of the neighboring cell's RSS, it cannot correctly generate the sequence of the neighboring cell's RSS, thus making it impossible to measure the RSS of the neighboring cell.

[0062] In summary, there is currently a problem where terminal devices cannot measure the RSS of neighboring cells.

[0063] To address the aforementioned issues, embodiments of this application provide a method, apparatus, and system for measuring RSS. A terminal device can determine the time-domain position of the RSS of a neighboring cell within the timing of that neighboring cell, determine the first sequence parameters of the RSS of that neighboring cell, and measure the RSS of that neighboring cell based on the time-domain position and the first sequence parameters of the RSS of that neighboring cell.

[0064] The RSS measurement method provided in this application is applicable to communication systems. Figure 1 One structure of the communication system is shown. For example... Figure 1 As shown, the communication system may include a network device 11 and a terminal device 12. The network device 11 and the terminal device 12 establish a connection using either wired or wireless communication.

[0065] Network device 11 is used to send RSS configuration information (first RSS configuration information, second RSS configuration information, or third RSS configuration information) about neighboring cells to terminal device 12.

[0066] In some embodiments, network device 11 is a device in a communication system that connects terminal device 12 to a wireless network. Network device 11 is a node in a wireless access network, and can be called a base station, a radio access network (RAN) node, or a device. Currently, some network devices 11 can be: gNB, transmission reception point (TRP), evolved node B (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved node B, or home node B, HNB), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP), etc. Additionally, in a network architecture, network device 11 can include centralized unit (CU) nodes and distributed unit (DU) nodes. This structure separates the protocol layer of the eNB in ​​the LTE system. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0067] It should be noted that, in this embodiment, the serving cell and the neighboring cell may belong to the same network device 11. Alternatively, the serving cell and the neighboring cell may belong to different network devices. The serving cell belongs to network device 11, and the neighboring cell belongs to other network devices.

[0068] Terminal device 12 is configured to receive RSS configuration information about neighboring cells sent by network device 11 in the serving cell. Terminal device 12 is further configured to determine the time domain position of the neighboring cell's RSS in the timing of the neighboring cell according to the first RSS configuration information or the first preset rule, and determine the first sequence parameter of the neighboring cell's RSS according to the third RSS configuration information or the second preset rule, and measure the RSS of the neighboring cell according to the time domain position and the first sequence parameter of the cell's RSS.

[0069] In some embodiments, terminal device 12 may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, or a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the RAN. For example, terminal device 12 may be: a mobile phone, tablet computer, laptop computer, PDA, mobile internet device (MID), wearable device, virtual reality (VR) device, augmented reality (AR) device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, wireless terminal device in smart home, etc. Figure 1 The example shown is a mobile phone as the terminal device 12.

[0070] The basic hardware structures of the network device 11 and the terminal device 12 are similar, both including Figure 2 The components included in the communication device shown. The following are examples... Figure 2 Taking the communication device shown as an example, the hardware structure of network device 11 and terminal device 12 will be introduced.

[0071] like Figure 2 As shown, the communication device may include a processor 21 (or a processing circuit) and a communication interface 22 (or an interface circuit), the communication interface 22 being used to communicate with other devices or equipment.

[0072] Optionally, the communication device may further include a memory 23 for storing computer instructions. The processor 21 and the memory 23 are coupled to each other for implementing the RSS measurement method provided in the embodiments of this application below. Alternatively, the communication device may not include the memory 23, and the memory 23 may be located outside the communication device.

[0073] The processor 21, memory 23, and communication interface 22 are coupled together to implement the RSS measurement method provided in the following embodiments of this application. For example, when the processor 21 executes computer instructions stored in the memory 23, it causes the communication device to execute the RSS measurement method provided in the following embodiments of this application. Exemplarily, the communication device is a communication device (terminal device or network device), or a chip or other component disposed within the communication device.

[0074] If the communication device is a communication equipment, the communication interface 22 is implemented, for example, through a transceiver (or transmitter and receiver) in the communication equipment. The transceiver may be implemented through an antenna, feeder, and codec in the communication equipment. Alternatively, if the communication device is a chip located within the communication equipment, the communication interface 22 is, for example, the chip's input / output interface, such as input / output pins. This communication interface 22 is connected to the radio frequency transceiver components in the communication equipment to transmit and receive information via the radio frequency transceiver components.

[0075] Processor 21 is the control center of the communication device. It can be a single processor or a collective term for multiple processing elements. For example, processor 21 can be a general-purpose central processing unit (CPU) or other general-purpose processors. Among them, the general-purpose processor can be a microprocessor or any conventional processor, such as a graphics processing unit (GPU) or a digital signal processing unit (DSP).

[0076] The memory 22 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), disk storage media or other magnetic storage devices, or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer, but is not limited thereto.

[0077] In this embodiment, the software programs stored in the memory 22 are different for network device 11 and terminal device 12, therefore the functions implemented by network device 11 and terminal device 12 are different. The functions performed by each device will be described with reference to the following flowchart.

[0078] Communication interface 23 is used for connecting the communication device to other devices via a communication network, such as Ethernet, RAN, wireless local area networks (WLAN), etc. Communication interface 23 may include a receiving unit for receiving data and a transmitting unit for sending data.

[0079] It should be pointed out that, Figure 2 The structure shown does not constitute a limitation on the communication device, except Figure 2 In addition to the components shown, the communication device may include more or fewer components than illustrated, or combine certain components, or have different component arrangements.

[0080] Based on the above description of the hardware structure of the communication system and communication device, this application provides an RSS measurement method. The RSS measurement method provided in this application is described below with reference to the accompanying drawings. This RSS measurement method is applied in a scenario where the terminal device defaults to the neighboring cell having the same RSS period as the serving cell, and the time-domain location of the neighboring cell's RSS is determined.

[0081] It should be noted that, in the embodiments of this application, the neighboring cell can refer to a cell that is physically adjacent to the serving cell, or it can refer to a cell that is not physically adjacent to the serving cell. The embodiments of this application do not limit the physical location of the neighboring cell.

[0082] When RSS measurement methods are applied Figure 1 When the communication system shown is used, such as Figure 3 As shown, the method for measuring RSS may include the following steps 301-303.

[0083] 301. The terminal device determines its time domain location.

[0084] This time-domain location refers to the time-domain position of the neighboring cell's RSS within the neighboring cell's timing. The neighboring cell's timing refers to the time reference of its transmission resources.

[0085] Since RSS occurs periodically, the terminal device can first determine the time-domain position of the first occurrence of the neighboring cell's RSS within the neighboring cell's timing. Therefore, it can deduce all the time-domain positions of the neighboring cell's RSS within the neighboring cell's timing based on the period of the neighboring cell's RSS. This time-domain position can include at least one of the frames or subframes containing the neighboring cell's RSS.

[0086] Specifically, the terminal device can use the following three methods to determine the time domain position of the first occurrence of the neighboring cell's RSS in the neighboring cell's timing.

[0087] Method 1: The time-domain location can be determined by the terminal device based on the first RSS configuration information of the network device.

[0088] Method 2: The time domain location can be determined by the terminal device according to the first preset rule.

[0089] Method 3: The frame containing the neighboring cell's RSS in the time domain can be determined by the terminal device by checking whether it has received the second RSS configuration information sent by the network device. For example, if the timing of the serving cell and the neighboring cell are the same, when the terminal device receives the second RSS configuration information, it can determine the first frame of the neighboring cell's RSS in the serving cell's timing based on the second RSS configuration information, and identify the frame in the neighboring cell's timing that overlaps with the first frame as the frame containing the neighboring cell's RSS. Alternatively, if the terminal device does not receive the second RSS configuration information, it can obtain the frame of the serving cell's RSS in the serving cell's timing, and identify the frame in the neighboring cell's timing that overlaps with that frame as the frame containing the neighboring cell's RSS. The subframe containing the neighboring cell's RSS in the time domain can be obtained by the terminal device from other channels. For example, the subframe containing the neighboring cell's RSS can be pre-set in the terminal device, which the terminal device can directly obtain.

[0090] This application does not limit the specific method used to determine the time-domain location in its embodiments.

[0091] 302. The terminal device determines the first sequence parameter of the RSS of the neighboring cell.

[0092] The first sequence parameter of a neighboring cell's RSS is a parameter used to generate the sequence of events for that neighboring cell's RSS. For example, the first sequence parameter can be 'u'. Optionally, information related to the first sequence parameter can be configured in the neighboring cell's systemInfoUnchanged-BR-r15 information cell. The first sequence parameters of RSS may differ between different cells.

[0093] Specifically, the terminal device can determine the first sequence parameter of the RSS of the neighboring cell in the following three ways.

[0094] In Method 1, the first sequence parameter of the neighboring cell's RSS can be determined by the terminal device based on the third RSS configuration device of the network device.

[0095] Method 2: The first sequence parameter of the neighboring cell's RSS can be determined by the terminal device according to the second preset rule.

[0096] Method 3: The first sequence parameter of the neighboring cell's RSS can be obtained by the terminal device from other channels. For example, the first sequence parameter can be pre-set in the terminal device, which can directly obtain it.

[0097] This application does not limit the specific method used to determine the first sequence parameters in the embodiments.

[0098] It should be noted that, in this embodiment, the execution of steps 301 and 302 is not sequential. That is, the time-domain position of the neighboring cell's RSS within the neighboring cell's timing and the first sequence parameter of the neighboring cell's RSS can be determined simultaneously by the terminal device. For example, both can be determined by the terminal device based on the network device's configuration information. Alternatively, they can be determined using the same configuration information (i.e., the first RSS configuration information and the third RSS configuration information are the same). Or, the time-domain position of the neighboring cell's RSS within the neighboring cell's timing and the first sequence parameter of the neighboring cell's RSS may not be determined simultaneously by the terminal device. For example, one of them can be determined by the terminal device based on the network device's configuration information, and the other can be determined by the terminal device based on a corresponding preset rule. Alternatively, both can be determined by the terminal device separately based on corresponding preset rules.

[0099] Furthermore, when the terminal device in this embodiment uses method 3 in step 301 to determine the time-domain location, it needs to use one of methods 1 and 2 in step 302 to determine the first sequence parameter of the neighboring cell's RSS. Similarly, when the terminal device in this embodiment uses method 3 in step 302 to determine the first sequence parameter, it needs to use one of methods 1 and 2 in step 301 to determine the time-domain location. Of course, the terminal device in this embodiment can also use one of methods 1 and 2 in step 301 to determine the time-domain location and use one of methods 1 and 2 in step 302 to determine the first sequence parameter.

[0100] 303. The terminal device measures the RSS of the neighboring cell based on the time domain location and the first sequence parameter of the neighboring cell's RSS.

[0101] The terminal device can generate the RSS sequence of the neighboring cell based on all time-domain positions of the neighboring cell's RSS during the timing of the neighboring cell, as well as the first sequence parameter of the neighboring cell's RSS, thereby measuring the RSS of the neighboring cell.

[0102] The RSS measurement method provided in this application allows a terminal device to determine the time-domain position of a neighboring cell's RSS within the timing of that neighboring cell, as well as the first sequence parameters of that neighboring cell's RSS. Then, based on the time-domain position and the first sequence parameters of the neighboring cell's RSS, the RSS of the neighboring cell is measured. This solves the problem that terminal devices cannot measure the RSS of neighboring cells, especially enabling the measurement of the neighboring cell's RSS when the serving cell and the neighboring cell are asynchronous. Accurate measurement of the neighboring cell's RSS provides the possibility for further measurement of the neighboring cell's RSRP, thus providing a basis for the terminal device to subsequently perform cell reselection or measurement reporting.

[0103] Optionally, in the embodiments of this application, based on Figure 3 ,like Figure 4 As shown, when the time-domain location is determined by the terminal device based on the first RSS configuration information of the network device, the RSS measurement method provided in this application embodiment may further include the following step 301A, and the above step 301A may specifically include the following steps 301B-301C.

[0104] 301A. The network device sends the first RSS configuration information about the neighboring cell to the terminal device.

[0105] Specifically, the network device can first determine the first RSS configuration information about the neighboring cell, and then send the first RSS configuration information to the terminal device. The first RSS configuration information carries first information, which is used to indicate the time domain position of the neighboring cell's RSS in the timing of the neighboring cell.

[0106] It is understood that the first information carried in the aforementioned first RSS configuration information can be determined by the network device in different ways. Specifically, when the serving cell and the neighboring cell belong to the same network device, the network device can directly determine the first information and send it to the terminal device along with the first RSS configuration information. When the serving cell and the neighboring cell belong to different network devices, the network device of the serving cell can obtain the first information by communicating with the network device of the neighboring cell and send it to the terminal device along with the first RSS configuration information. Figure 4 The example shown is based on the fact that the serving cell and the neighboring cell belong to the same network device.

[0107] Furthermore, the first information carried in the aforementioned first RSS configuration information can be information that directly indicates the time-domain location. Alternatively, the first information can be information that indirectly indicates the time-domain location; that is, the time-domain location needs to be derived from the first information.

[0108] 301B. The terminal device receives the first RSS configuration information sent by the network device in the serving cell.

[0109] The terminal device can receive first RSS configuration information from the network device in the serving cell. The first RSS configuration information carries first information indicating the time domain position of the RSS of the neighboring cell in the timing of the neighboring cell. The serving cell belongs to the network device.

[0110] 301C: The terminal device determines the time domain location based on the first information.

[0111] When the first information includes information indicating the target frame of the neighboring cell's RSS within the timing of the neighboring cell and the frame overlapping with the first frame, the terminal device determining the time-domain location based on the first information may specifically include: the terminal device determining that the frame containing the neighboring cell's RSS is the target frame. Here, the first frame is the frame of the neighboring cell's RSS within the timing of the serving cell, i.e., a frame within the transmission resources of the serving cell. Since the timing of the neighboring cell may differ from that of the serving cell, the number of frames overlapping with the first frame within the timing of the neighboring cell's RSS may be more than one; for example, there may be two frames overlapping with the first frame. In this case, the first information is used to indicate which of these two frames is the target frame.

[0112] When the first information includes information for indicating the configuration of the BL / CE subframe of the neighboring cell, the terminal device determining the time domain location based on the first information may specifically include: the terminal device determining that the subframe in which the RSS of the neighboring cell is located is the BL / CE subframe within the frame in which the RSS of the neighboring cell is located.

[0113] When the first information includes information indicating the target frame of the neighboring cell's RSS in the timing of the neighboring cell and the frame overlapping with the first frame, and information indicating the configuration of the neighboring cell's BL / CE subframe, the terminal device can determine the time domain location based on the first information. Specifically, the terminal device can determine that the frame where the neighboring cell's RSS is located is the target frame, and determine that the subframe where the neighboring cell's RSS is located is the BL / CE subframe within the target frame.

[0114] based on Figure 3 ,like Figure 4 As shown, when the time domain location is determined by the terminal device according to the first preset rule, the above step 301 may specifically include the following step 301D.

[0115] 301D, the terminal device determines the time domain location according to the first preset rule.

[0116] When the time-domain location includes the frame where the RSS of the neighboring cell is located, the process by which the terminal device determines the time-domain location according to the first preset rule is as follows: The terminal device can determine the frame of the neighboring cell's RSS in the serving cell's timing according to the second RSS configuration information about the neighboring cell, that is, determine the first frame, and determine the frame in the timing of the neighboring cell that is closest to the first frame as the frame where the neighboring cell's RSS is located, or determine the frame in the timing of the neighboring cell that has the largest overlap time with the first frame as the frame where the neighboring cell's RSS is located.

[0117] The process by which a terminal device determines the frame closest to the first frame or the frame with the longest overlap time with the first frame during timing in neighboring cells can be as follows: The terminal device first determines the frames overlapping with the first frame during timing in neighboring cells. For these overlapping frames, the terminal device determines the distance between the header of each overlapping frame and the header of the first frame. Finally, the terminal device determines the overlapping frame corresponding to the minimum distance as the frame closest to the first frame or the frame with the longest overlap time. Alternatively, the terminal device can calculate the distance between the tail of each overlapping frame and the tail of the first frame, and determine the overlapping frame corresponding to the minimum distance as the frame closest to the first frame or the frame with the longest overlap time.

[0118] When the time-domain location includes the subframe containing the RSS of a neighboring cell, the process by which the terminal device determines the time-domain location according to the first preset rule is as follows: The terminal device obtains the configuration of the BL / CE subframe of the serving cell and determines the BL / CE subframe within the frame containing the RSS of the neighboring cell, whose configuration is the same as that of the BL / CE subframe of the serving cell, as the subframe containing the RSS of the neighboring cell. In other words, the terminal device assumes that the configuration of the BL / CE subframe of the neighboring cell is the same as that of the BL / CE subframe of the serving cell. In this case, the terminal device only meets the requirement of measuring the RSS of the neighboring cell if the actual configuration of the BL / CE subframe of the neighboring cell is the same as the assumed configuration.

[0119] When the time-domain location includes the frame where the neighboring cell's RSS is located and the subframe where the neighboring cell's RSS is located, the process by which the terminal device determines the time-domain location according to the first preset rule is as follows: The terminal device can determine the frame in the timing of the neighboring cell that is closest to the first frame as the frame where the neighboring cell's RSS is located, and determine the BL / CE subframe within the frame where the neighboring cell's RSS is located that has the same configuration as the BL / CE subframe of the serving cell as the subframe where the neighboring cell's RSS is located.

[0120] In existing technologies, when a terminal device determines that the time-domain position of a neighboring cell's RSS based on the neighboring cell's timing is the same as the time-domain position of the serving cell's RSS based on the serving cell's timing, or when determining the time-domain position of the neighboring cell's RSS based on the neighboring cell's timing based on a time-domain offset, it determines the first frame of the neighboring cell's RSS within the serving cell's timing, and then determines the frame overlapping with the first frame within the neighboring cell's timing. In asynchronous scenarios, the terminal device will identify two overlapping frames, and in this case, the terminal device cannot determine in which of these two frames the neighboring cell's RSS was sent.

[0121] For example, such as Figure 5 As shown, assume the first frame of the neighboring cell's RSS in the serving cell's timing is n. In asynchronous scenarios, the terminal device can determine the position of the frame header of the neighboring cell's transmission resources by detecting the neighboring cell's Primary / Secondary Synchronization Signal (PSS / SSS). In this case, by Figure 5 It can be seen that the terminal device identifies two frames overlapping with frame n during the timing of the neighboring cell, namely frame (m-1) and frame m. At this time, the terminal device cannot determine whether the RSS of the neighboring cell is sent in frame (m-1) or in frame m.

[0122] In addition, since the existing standard stipulates that the starting subframe for sending RSS is the first BL / CE subframe within the frame in which RSS is sent, the terminal device can only know the configuration of the BL / CE subframe of the serving cell and cannot know the configuration of the BL / CE subframe of the neighboring cell. This makes it impossible to determine the subframe position of the neighboring cell's RSS within its own frame, and thus impossible to measure the RSS of the neighboring cell.

[0123] In this embodiment, the terminal device can determine the frames of the neighboring cell's RSS in the timing of the neighboring cell through the configuration of the network device or a first preset rule (in combination with...). Figure 5 The terminal device can determine whether the neighboring cell's RSS is located in the frame (m-1) or frame m in the neighboring cell's timing, or in the subframe where the neighboring cell's RSS is located. The method of determining the frame or subframe where the neighboring cell's RSS is located through network device configuration allows each cell to configure different time-domain locations for its RSS, increasing network flexibility. The method of determining the frame or subframe where the neighboring cell's RSS is located through a first preset rule can achieve this without adding extra signaling, effectively saving system resources.

[0124] Optionally, in the embodiments of this application, based on Figure 4 ,like Figure 6As shown, when the first sequence parameter of the neighboring cell's RSS is determined by the terminal device according to the configuration of the network device, the RSS measurement method provided in this application embodiment may further include the following step 302A, and the above step 302 may specifically include the following steps 302B-302C.

[0125] 302A. The network device sends third-party RSS configuration information about neighboring cells to the terminal device.

[0126] Specifically, network devices can first determine the third RSS configuration information about neighboring cells, and then send this third RSS configuration information to terminal devices. The third RSS configuration information carries second information, which indicates the first sequence parameters for determining the RSS of neighboring cells.

[0127] It is understood that the second information carried in the aforementioned third RSS configuration information can be obtained by the network device through different methods. For a specific description of the method of obtaining the second information, please refer to the relevant description of the method of obtaining the first information in step 301A above, which will not be repeated here in this embodiment of the application.

[0128] Furthermore, the second information carried in the aforementioned third RSS configuration information can be information that directly indicates the first sequence parameters. Alternatively, the second information can be information that indirectly indicates the first sequence parameters; that is, the first sequence parameters need to be derived from the second information.

[0129] 302B. The terminal device receives third-party RSS configuration information sent by the network device in the serving cell.

[0130] The terminal device can receive third RSS configuration information from neighboring cells of the network device in the serving cell. The third RSS configuration information carries second information for indicating the first sequence parameters of the neighboring cell's RSS.

[0131] 302C. The terminal device determines the first sequence parameter of the neighboring cell's RSS based on the second information.

[0132] based on Figure 4 ,like Figure 6 As shown, when the first sequence parameter of the neighboring cell's RSS is determined by the terminal device according to the second preset rule, the above step 302 may specifically include the following step 302D.

[0133] 302D: The terminal device determines the first sequence parameters of the RSS of the neighboring cell according to the second preset rule.

[0134] The terminal device can first obtain the first sequence parameter of the RSS of the serving cell, and then determine the first sequence parameter of the RSS of the serving cell as the first sequence parameter of the RSS of the neighboring cell. In other words, the terminal device can assume that the value of u in the RSS of the neighboring cell is the same as the value of u in the RSS of the serving cell. In this case, the terminal device only meets the requirement of measuring the RSS of the neighboring cell if the actual value of the first sequence parameter of the RSS of the neighboring cell is the same as the assumed value.

[0135] Because the terminal device cannot obtain the first sequence parameter of the neighboring cell's RSS, it cannot correctly generate the sequence of the neighboring cell's RSS, thus making it impossible to measure the neighboring cell's RSS.

[0136] In this embodiment, the terminal device can determine the first sequence parameter of the RSS of a neighboring cell through the configuration of the network device or a second preset rule. The method of determining the first sequence parameter of the RSS of a neighboring cell through the configuration of the network device ensures that the terminal device can still correctly measure the RSS of neighboring cells even when different cells have different first sequence parameters for their RSS. The method of determining the first sequence parameter of the RSS of a neighboring cell through the second preset rule allows for the determination of the value of the first sequence parameter without adding extra signaling.

[0137] Optionally, in this embodiment, after performing step 303, the terminal device can obtain the first RSRP of the neighboring cell based on the measurement result of the RSS of the neighboring cell. Furthermore, the terminal device can measure the RSS of the serving cell based on the time-domain position of the serving cell's RSS in the serving cell's timing and the first sequence parameters of the serving cell's RSS, and obtain the second RSRP of the serving cell based on the measurement result. Afterwards, the terminal device can perform cell reselection or measurement reporting based on the first RSRP and the second RSRP.

[0138] A terminal can obtain the cell's RSRP and reference signal received quality (RSRQ) by measuring the cell's CRS. Based on the RSRP and RSRQ of neighboring cells and the serving cell, the terminal can then perform cell reselection or measurement reporting. Under certain conditions, cell measurements can be performed based on RSS. In this case, cell reselection or measurement reporting can be performed solely based on RSRP, and measuring RSRP based on RSS is more effective than measuring RSRP based on CRS.

[0139] It should be noted that the triggering condition for executing the RSS measurement method of this application embodiment when the terminal device is in a connected state can be changed. In the prior art, the terminal device triggers the execution of the RSS measurement method when it receives second RSS configuration information about neighboring cells sent by the network device. In this application embodiment, the terminal device triggers the execution of the RSS measurement method only when it receives second RSS configuration information about neighboring cells sent by the network device and determines that RSRQ is not configured as a reference value for measurement reporting in the measurement reporting configuration sent by the network device.

[0140] Optionally, in this embodiment, when the terminal device determines the frame of the neighboring cell's RSS in the serving cell's timing (i.e., determines the first frame), it can first determine a target value based on the second RSS configuration information about the neighboring cell received by the terminal device in the serving cell. Then, it uses the target value to perform a modulo operation on the period of the neighboring cell's RSS, and finally determines the frame number of the first frame using the result of the modulo operation. This overcomes the problem that the frame number directly calculated without performing the modulo operation may exceed the range of the neighboring cell's RSS period. For example, assuming the neighboring cell's RSS period is 160 milliseconds, or 16 frames, the range of the frame number calculated by the terminal device should be between [0, 1, 2, 3, 4... 15]. However, without performing the modulo operation, the directly calculated frame number may be greater than 15. This embodiment effectively avoids the problem of the calculated frame number exceeding the range of the neighboring cell's RSS period by performing the modulo operation.

[0141] It can be understood that the period of the RSS of the neighboring cell mentioned above is in frames, which is obtained by dividing the period of the RSS of the neighboring cell (in milliseconds) by 10 (10 means that a frame is 10 milliseconds).

[0142] It should be noted that the RSS configuration information carrying the first information (first RSS configuration information), the RSS configuration information carrying the second information (third RSS configuration information), and the RSS configuration information used to determine the first frame (second RSS configuration information) involved in the above embodiments can be the same piece of information, such as the same piece of RSS configuration information, or they can be different pieces of information.
