Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, and system for measuring a resynchronization signal (RSS). Background Art

[0002] Radio resource management (RRM) measurements refer to measurements performed by a terminal device to assist mobility management (such as switching or reselection of a terminal device). RRM measurements may include reference signal received power (RSRP) measurements. In enhanced machine type communication (eMTC), a terminal device can measure the RSRP of a cell by measuring the RSS of the cell. However, in certain situations, such as when the serving cell and the neighboring cell are asynchronous, the terminal device cannot measure the RSS of the neighboring cell, resulting in the inability to measure the RSRP of the neighboring cell by measuring the RSS of the neighboring cell, thereby reducing the reliability of communication. Summary of the Invention

[0003] The present application provides a method, device and system for measuring RSS, which solves the problem that a terminal device cannot measure the RSS of a neighboring cell.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] In a first aspect, the present application provides a method for measuring an RSS, wherein a terminal device determines a time domain position, which is the time domain position of the RSS of a neighboring cell in the timing of the neighboring cell, and determines a first sequence parameter of the RSS of the neighboring cell. The terminal device then measures the RSS of the neighboring cell based on the time domain position and the first sequence parameter of the RSS of the neighboring cell.

[0006] In this way, the terminal device can determine the time domain position of the neighboring cell's RSS in the timing of the neighboring cell, as well as the first sequence parameter of the neighboring cell's RSS, and thus can measure the neighboring cell's RSS based on the time domain position and the first sequence parameter of the neighboring cell's RSS, solving the problem that the terminal device cannot measure the neighboring cell's RSS, especially when the serving cell and the neighboring cell are asynchronous. By accurately measuring the neighboring cell's RSS, it is possible to further measure the neighboring cell's RSRP, thereby providing a basis for the terminal device to subsequently perform cell reselection or measurement reporting.

[0007] Optionally, in a possible implementation of the present application, the time domain position includes at least one of the following: a frame where the RSS of the neighboring cell is located, and a subframe where the RSS of the neighboring cell is located.

[0008] Optionally, in another possible implementation of the present application, the above-mentioned method of "determining the time domain location" may include: the terminal device receives first RSS configuration information about a neighboring cell in a serving cell, the first RSS configuration information carrying first information for indicating the time domain location, and the terminal device determines the time domain location based on the first information. Alternatively, the terminal device determines the time domain location based on a first preset rule.

[0009] In this way, the terminal device can determine the time domain location using either of the two aforementioned methods. Alternatively, the terminal device can first determine whether the time domain location can be determined based on the first RSS configuration information. If so, the terminal device directly determines the time domain location based on the first RSS configuration information. If not, the terminal device determines the time domain location based on the first preset rule.

[0010] The terminal device can determine the frame of the neighboring cell's RSS in the neighboring cell's timing, or the subframe in which the neighboring cell's RSS is located, through the configuration of the network device or the first preset rule. The method of determining the frame or subframe in which the neighboring cell's RSS is located through the configuration of the network device allows each cell to configure a different time domain location for the RSS, thereby increasing network flexibility. The method of determining the frame or subframe in which the neighboring cell's RSS is located through the first preset rule can determine the frame or subframe in which the neighboring cell's RSS is located in the neighboring cell's timing without adding additional signaling, thereby effectively saving system resources.

[0011] Optionally, in another possible implementation of the present application, the first information includes information for indicating a target frame in a frame overlapping with the first frame in the timing of the neighboring cell, and in a case where the first frame is a frame in which the RSS of the neighboring cell is in the timing of the serving cell, the above-mentioned method of "determining the time domain position based on the first information" may include: the terminal device determines that the frame in which the RSS of the neighboring cell is located is the target frame. Since the timing of the neighboring cell may be different from the timing of the serving cell, the number of frames in which the RSS of the neighboring cell is in the timing of the neighboring cell and overlaps with the first frame may be more than one. For example, there may be two frames that overlap with the first frame. In this case, the first information is used to indicate which of the two frames is the target frame.

[0012] Optionally, in another possible implementation of the present application, when the first information includes information for indicating the configuration of a bandwidth limited / coverage enhanced (BL / CE) subframe of a neighboring cell, the above-mentioned method of "determining the time domain position based on the first information" may include: the terminal device determines that the subframe where the RSS of the neighboring cell is located is the BL / CE subframe within the frame where the RSS of the neighboring cell is located.

[0013] Optionally, in another possible implementation of the present application, the first information includes information for indicating a target frame in a frame overlapping with the first frame in the timing of the neighboring cell and the RSS of the neighboring cell, and information for indicating the configuration of the BL / CE subframe of the neighboring cell. In the case where the first frame is a frame in the timing of the neighboring cell's RSS in the serving cell, the above-mentioned method of "determining the time domain position based on the first information" may include: the terminal device determines that the frame in which the RSS of the neighboring cell is located is the target frame, and determines that the subframe in which the RSS of the neighboring cell is located is the BL / CE subframe within the target frame.

[0014] Optionally, in another possible implementation of the present application, when the time domain position includes the frame where the RSS of the neighboring cell is located, the above-mentioned method of "determining the time domain position 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 based on the second RSS configuration information about the neighboring cell.

[0015] Optionally, in another possible implementation of the present application, when the time domain position includes the subframe where the RSS of the neighboring cell is located, the above-mentioned method of "determining the time domain position according to the first preset rule" may include: the terminal device determines the BL / CE subframe within the frame where the RSS of the neighboring cell is located and having the same configuration as the BL / CE subframe of the serving cell as the subframe where the RSS of the neighboring cell is located.

[0016] Optionally, in another possible implementation of the present application, when the time domain position includes the frame where the RSS of the neighboring cell is located and the subframe where the RSS of the neighboring cell is located, the above-mentioned method of "determining the time domain position 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 based on the second RSS configuration information about the neighboring cell; and determines the BL / CE subframe within the frame where the RSS of the neighboring cell is located and having the same configuration as the BL / CE subframe of the serving cell as the subframe where the RSS of the neighboring cell is located.

[0017] Optionally, in another possible implementation of the present application, the method of "determining the first sequence parameter of the RSS of a neighboring cell" 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 parameter of the RSS of the neighboring cell; and determining the first sequence parameter of the RSS of the neighboring cell based on the second information. Alternatively, the terminal device determines the first sequence parameter of the RSS of the neighboring cell based on a second preset rule.

[0018] The terminal device can determine the first sequence parameters of the RSS of the neighboring cell through the configuration of the network device or the second preset rule. Among them, the method of determining the first sequence parameters of the RSS of the neighboring cell through the configuration of the network device ensures that the terminal device can still correctly measure the RSS of the neighboring cell under the condition that each cell is configured with different first sequence parameters of the RSS. The method of determining the first sequence parameters of the RSS of the neighboring cell through the second preset rule can clarify the value of the first sequence parameters without adding additional signaling.

[0019] Optionally, in another possible implementation of the present application, the above-mentioned 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 determines the first sequence parameter of the RSS of the serving cell as the first sequence parameter of the RSS of the neighboring cell.

[0020] Optionally, in another possible implementation of the present application, the RSS measurement method provided in the present application may further include: the terminal device obtains a first reference signal received power (RSRP) of the neighboring cell based on the measurement result of the RSS of the neighboring cell. The terminal device measures the RSS of the serving cell, and obtains a second RSRP of the serving cell based on the measurement result of the RSS of the serving cell. The terminal device then performs cell reselection or measurement reporting based on the first RSRP and the second RSRP.

[0021] The terminal can obtain the RSRP and reference signal received quality (RSRQ) of the cell by measuring the CRS of the cell, and then perform cell reselection or measurement reporting based on the RSRP and RSRQ of the neighboring cell and the RSRP and RSRQ of the serving cell. When certain conditions are met, the cell measurement is based on the RSS. In this case, the cell reselection or measurement reporting can be based only on the RSRP, and the effect of measuring RSRP based on the RSS is better than that of measuring RSRP based on the CRS.

[0022] Optionally, in another possible implementation of the present application, the RSS measurement method provided in the present application may further include: the terminal device uses the target value to perform a modulo operation on the period of the RSS of the neighboring cell, and determines the result of the modulo operation as the frame number of the first frame. 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 RSS of the neighboring cell in 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 period of the neighboring cell RSS.

[0029] In a seventh aspect, the present 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 RSS of the neighboring cell in the timing of the neighboring cell.

[0030] In this way, the first RSS configuration information is sent to the terminal device through the network device so that 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, allowing each cell to configure different time domain positions of the RSS, thereby increasing network flexibility.

[0031] Optionally, in a possible implementation of the present application, the time domain position includes at least one of the following: a frame where the RSS of the neighboring cell is located, and a subframe where the RSS of the neighboring cell is located.

[0053] In the embodiments of this application, words such as "for example" and "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "for example" is intended to present the relevant concepts in a concrete manner.

[0054] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "plurality" means two or more.

[0055] One method for measuring the RSRP of a neighboring cell is to measure the cell reference signal (CRS) of the neighboring cell. When a terminal device measures the CRS of a neighboring cell, it must first determine the time domain location of the CRS of the neighboring cell. The CRS of the neighboring cell is transmitted in every subframe, so the terminal device can measure the CRS of the neighboring cell in any subframe within the transmission resources of the neighboring cell.

[0056] With the rapid development of communication technology, RSS-based RSRP measurement has been introduced in the long-term evolution (LTE) eMTC system. Measuring RSRP by measuring the RSS of neighboring cells has the advantages of shorter measurement period and higher measurement accuracy compared to measuring RSRP by measuring the CRS of neighboring cells.

[0057] When a terminal device measures the RSS of a neighboring cell, it must first 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 the terminal device to determine the time domain location of the RSS of all periodic neighboring cells. Finally, by measuring the RSS of neighboring cells over multiple periods, the RSRP of the neighboring cell can be obtained.

[0058] However, in the case of cell asynchrony (the timing of the neighboring cell is different from the timing 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 neighboring cell's timing, resulting in the inability to measure the neighboring cell's RSS.

[0059] In addition, since the terminal device cannot obtain the first sequence parameter of the RSS of the neighboring cell, it cannot correctly generate the sequence of the RSS of the neighboring cell, thereby failing to measure the RSS of the neighboring cell.

[0060] In summary, there is currently a problem that a terminal device cannot measure the RSS of a neighboring cell.

[0061] In order to solve the above problems, the embodiments of the present application provide an RSS measurement method, apparatus and system, in which the terminal device can determine the time domain position of the RSS of a neighboring cell in the timing of the neighboring cell, and determine the first sequence parameters of the RSS of the neighboring cell, and measure the RSS of the neighboring cell based on the time domain position and the first sequence parameters of the RSS of the neighboring cell.

[0062] The RSS measurement method provided in the embodiment of the present application is applicable to a communication system. Figure 1 FIG. 1 shows a structure of the communication system. 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 a wired communication method or a wireless communication method.

[0063] The network device 11 is configured to send RSS configuration information (first RSS configuration information, second RSS configuration information, or third RSS configuration information) about a neighboring cell to the terminal device 12 .

[0064] In some embodiments, the network device 11 is a device in a communication system that connects the terminal device 12 to a wireless network. The network device 11 is a node in a radio access network, which can be called a base station, or a radio access network (RAN) node or 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 (Wifi) access point (AP). In addition, in one network structure, the network device 11 can include a centralized unit (CU) node and a distributed unit (DU) node. This structure splits the protocol layer of the eNB in ​​the LTE system, placing some of the protocol layer functions in the CU for centralized control, and distributing some or all of the remaining protocol layer functions in the DU, which is centrally controlled by the CU.

[0065] It should be noted that in the embodiment of the present application, 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 the network device 11, and the neighboring cell belongs to another network device.

[0066] The terminal device 12 is configured to receive, in the serving cell, RSS configuration information about the neighboring cell sent by the network device 11. The terminal device 12 is further configured to determine, based on the first RSS configuration information or the first preset rule, a time domain position of the RSS of the neighboring cell in the timing of the neighboring cell, and determine, based on the third RSS configuration information or the second preset rule, a first sequence parameter of the RSS of the neighboring cell, and measure the RSS of the neighboring cell based on the time domain position and the first sequence parameter of the RSS of the cell.

[0067] In some embodiments, the 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-built-in, or vehicle-mounted mobile device that exchanges language and / or data with the RAN. For example, the terminal device 12 may be: a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self-driving (self-driving), a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in a smart city (smart city), a wireless terminal device in a smart home (smart home), etc. Figure 1 In the figure, the terminal device 12 is taken as a mobile phone as an example.

[0068] 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 are as follows. Figure 2 Taking the communication device shown as an example, the hardware structure of the network device 11 and the terminal device 12 is introduced.

[0069] like Figure 2As 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 may be used to communicate with other devices or equipment.

[0070] 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 to implement the RSS measurement method provided in the following embodiments of this application. Alternatively, the communication device may not include the memory 23; the memory 23 may be located external to the communication device.

[0071] The processor 21, the memory 23, and the communication interface 22 are coupled to each other to implement the RSS measurement method provided in the following embodiments of the present application. For example, when the processor 21 executes the computer instructions stored in the memory 23, the communication device executes the RSS measurement method provided in the following embodiments of the present application. Exemplarily, the communication device is a communication device (terminal device or network device), or a chip or other component provided in the communication device.

[0072] If the communication device is a communication device, the communication interface 22 is implemented, for example, by a transceiver (or transmitter and receiver) in the communication device, for example, the transceiver is implemented by an antenna, a feeder, and a codec in the communication device. Alternatively, if the communication device is a chip provided in the communication device, the communication interface 22 is, for example, an input / output interface of the chip, such as an input / output pin, etc. The communication interface 22 is connected to a radio frequency transceiver component in the communication device to transmit and receive information through the radio frequency transceiver component.

[0073] The processor 21 is the control center of the communication device and can be a single processor or a collective term for multiple processing elements. For example, the processor 21 can be a general-purpose central processing unit (CPU) or other general-purpose processor. The general-purpose processor can be a microprocessor or any conventional processor, for example, a graphics processing unit (GPU) or a digital signal processor (DSP).

[0074] The memory 22 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto.

[0075] In the embodiment of the present application, the network device 11 and the terminal device 12 have different software programs stored in the memory 22, so the network device 11 and the terminal device 12 implement different functions. The functions performed by each device will be described in conjunction with the following flowchart.

[0076] The communication interface 23 is used to connect the communication device to other devices via a communication network, which may be Ethernet, RAN, wireless local area network (WLAN), etc. The communication interface 23 may include a receiving unit for receiving data and a sending unit for sending data.

[0077] It should be pointed out that Figure 2 The structure shown in the figure does not constitute a limitation on the communication device. Figure 2 In addition to the components shown, the communication device may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0078] Based on the introduction of the hardware structure of the above-mentioned communication system and communication device, an embodiment of the present application provides a method for measuring RSS. The RSS measurement method provided by the embodiment of the present application is described below in conjunction with the accompanying drawings. The RSS measurement method is applied to a scenario where the terminal device defaults to the period of the RSS of the neighboring cell being the same as the period of the RSS of the serving cell, and determines the time domain position of the RSS of the neighboring cell.

[0079] It should be noted that the neighboring cell involved in the embodiments of the present application may refer to a cell that is physically adjacent to the serving cell, or may refer to a cell that is not physically adjacent to the serving cell. The embodiments of the present application do not limit the physical location of the neighboring cell.

[0080] When the RSS measurement method is applied to Figure 1 When the communication system shown in Figure 3As shown, the RSS measurement method may include the following steps 301 to 303.

[0081] 301. The terminal device determines the time domain location.

[0082] The time domain position is the time domain position of the RSS of the neighboring cell in the timing of the neighboring cell, wherein the timing of the neighboring cell refers to the time reference of the transmission resource of the neighboring cell.

[0083] Since RSS appears periodically, the terminal device can first determine the time domain position where the RSS of the neighboring cell first appears in the timing of the neighboring cell, and then calculate all time domain positions of the RSS of the neighboring cell in the timing of the neighboring cell based on the period of the RSS of the neighboring cell. The time domain position may include at least one of the frame where the RSS of the neighboring cell is located or the subframe where the RSS of the neighboring cell is located.

[0084] Specifically, the terminal device may use the following three methods to determine the time domain position where the RSS of the neighboring cell first appears in the timing of the neighboring cell.

[0085] In method 1, the time domain position can be determined by the terminal device according to the first RSS configuration information of the network device.

[0086] Method 2: The time domain position can be determined by the terminal device according to the first preset rule.

[0087] Method 3, the frame where the RSS of the neighboring cell in the time domain position is located can be determined by the terminal device by judging whether the second RSS configuration information sent by the network device is received. For example, when the timing of the serving cell is the same as the timing of the neighboring cell, when the terminal device receives the second RSS configuration information, it can determine the first frame of the RSS of the neighboring cell in the timing of the serving cell according to the second RSS configuration information, and determine the frame in the timing of the neighboring cell that overlaps with the first frame as the frame where the RSS of the neighboring cell is located. Alternatively, when the terminal device does not receive the second RSS configuration information, it can obtain the frame of the RSS of the serving cell in the timing of the serving cell, and determine the frame in the timing of the neighboring cell that overlaps with the frame as the frame where the RSS of the neighboring cell is located. The subframe where the RSS of the neighboring cell in the time domain position is located can be obtained by the terminal device from other channels. For example, the subframe where the RSS of the neighboring cell is located can be pre-set in the terminal device, and the terminal device can obtain it directly.

[0088] The embodiments of the present application do not limit the specific method used to determine the time domain position.

[0089] 302. The terminal device determines a first sequence parameter of the RSS of a neighboring cell.

[0090] The first sequence parameter of the RSS of a neighboring cell is a parameter used to generate the sequence of the RSS of the neighboring cell. For example, the first sequence parameter may be u. Optionally, information related to the first sequence parameter may be configured by the systemInfoUnchanged-BR-r15 information element of the neighboring cell. The first sequence parameter of the RSS of different cells may be different.

[0091] Specifically, the terminal device may determine the first sequence parameter of the RSS of the neighboring cell in the following three ways.

[0092] In mode 1, the first sequence parameter of the RSS of the neighboring cell may be determined by the terminal device according to the third RSS configuration device of the network device.

[0093] In mode 2, the first sequence parameter of the RSS of the neighboring cell may be determined by the terminal device according to a second preset rule.

[0094] In mode 3, the first sequence parameter of the RSS of the neighboring cell may be obtained by the terminal device from other channels. For example, the first sequence parameter may be pre-set in the terminal device and the terminal device may directly obtain it.

[0095] The embodiment of the present application does not limit the specific method for determining the first sequence parameter.

[0096] It should be noted that, in the embodiment of the present application, there is no order relationship between the execution of the above steps 301 and 302. That is to say, the time domain position of the RSS of the neighboring cell in the timing of the neighboring cell and the first sequence parameter of the RSS of the neighboring cell may be determined simultaneously by the terminal device. For example, both are determined by the terminal device according to the configuration information of the network device. For example, both are determined by the same configuration information (that is, the first RSS configuration information and the third RSS configuration information are the same configuration information). Alternatively, the time domain position of the RSS of the neighboring cell in the timing of the neighboring cell and the first sequence parameter of the RSS of the neighboring cell may not be determined simultaneously by the terminal device. For example, one of the two is determined by the terminal device according to the configuration information of the network device, and the other is determined by the terminal device according to the corresponding preset rules. Alternatively, both are determined by the terminal device according to the corresponding preset rules.

[0097] In addition, when the terminal device of the embodiment of the present application adopts the method 3 in the above step 301 to determine the time domain position, it is necessary to adopt one of the methods 1 and 2 in the above step 302 to determine the first sequence parameter of the RSS of the neighboring cell. Similarly, when the terminal device of the embodiment of the present application adopts the method 3 in the above step 302 to determine the first sequence parameter, it is necessary to adopt one of the methods 1 and 2 in the above step 301 to determine the time domain position. Of course, the terminal device of the embodiment of the present application may also adopt one of the methods 1 and 2 in the above step 301 to determine the time domain position, and adopt one of the methods 1 and 2 in the above step 302 to determine the first sequence parameter.

[0098] 303. The terminal device measures the RSS of the neighboring cell according to the time domain position and the first sequence parameter of the RSS of the neighboring cell.

[0099] The terminal device may generate a sequence of the RSS of the neighboring cell according to all time domain positions of the RSS of the neighboring cell in the timing of the neighboring cell and a first sequence parameter of the RSS of the neighboring cell, thereby measuring the RSS of the neighboring cell.

[0100] The RSS measurement method provided in the embodiment of the present application enables the terminal device to determine the time domain position of the RSS of the neighboring cell in the timing of the neighboring cell, and to determine the first sequence parameters of the RSS of the neighboring cell. Then, the RSS of the neighboring cell is measured based on the time domain position and the first sequence parameters of the RSS of the neighboring cell. This solves the problem that the terminal device cannot measure the RSS of the neighboring cell, especially when the serving cell and the neighboring cell are asynchronous, the RSS of the neighboring cell can be measured. By accurately measuring the RSS of the neighboring cell, it is possible to further measure the RSRP of the neighboring cell, thereby providing a basis for the terminal device to subsequently reselect the cell or report the measurement.

[0101] Optionally, in the embodiment of the present application, based on Figure 3 ,like Figure 4 As shown, when the time domain position is determined by the terminal device according to the first RSS configuration information of the network device, the RSS measurement method provided in the embodiment of the present application can also include the following steps 301A, and the above step 301 can specifically include the following steps 301B-301C.

[0102] 301A. The network device sends first RSS configuration information about a neighboring cell to the terminal device.

[0103] Specifically, the network device may first determine first RSS configuration information about the neighboring cell and then send the first RSS configuration information to the terminal device, wherein the first RSS configuration information carries first information for indicating the time domain position of the RSS of the neighboring cell in the timing of the neighboring cell.

[0104] It can be understood that the first information carried in the above-mentioned 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 carry it in the first RSS configuration information and send it to the terminal device. When the serving cell and the neighboring cell belong to different network devices, the network device to which the serving cell belongs can communicate with the network device to which the neighboring cell belongs to obtain the first information, and carry it in the first RSS configuration information and send it to the terminal device. Figure 4 The example in which the serving cell and the neighboring cell belong to the same network device is used.

[0105] In addition, the first information carried in the first RSS configuration information may be information that directly indicates the time domain location. The first information may also be information that indirectly indicates the time domain location, that is, the time domain location can only be obtained by deduction based on the first information.

[0106] 301B. The terminal device receives the first RSS configuration information sent by the network device in the serving cell.

[0107] The terminal device may receive first RSS configuration information from a network device in a serving cell, the first RSS configuration information carrying first information for indicating a time domain position of an RSS of a neighboring cell in a timing of the neighboring cell, wherein the serving cell belongs to the network device.

[0108] 301C. The terminal device determines the time domain position according to the first information.

[0109] In the case where the first information includes information for indicating a target frame in a frame that overlaps with the first frame in the timing of the neighboring cell and in the RSS of the neighboring cell, the terminal device determining the time domain position based on the first information may specifically include: the terminal device determining that the frame in which the RSS of the neighboring cell is located is the target frame. The first frame is the frame in which the RSS of the neighboring cell is in the timing of the serving cell, that is, the frame in the transmission resources of the serving cell. Since the timing of the neighboring cell may be different from the timing of the serving cell, the number of frames in which the RSS of the neighboring cell overlaps with the first frame in the timing of the neighboring cell may be more than one. For example, there may be two frames that overlap with the first frame. In this case, the first information is used to indicate which of the two frames is the target frame.

[0110] In the case where 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 position based on the first information may specifically include: the terminal device determining that the subframe where the RSS of the neighboring cell is located is the BL / CE subframe within the frame where the RSS of the neighboring cell is located.

[0111] In the case where the first information includes information for indicating a target frame in a frame overlapping with the first frame in the timing of the neighboring cell's RSS, and information for indicating the configuration of the neighboring cell's BL / CE subframe, the terminal device determining the time domain position based on the first information can specifically 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.

[0112] based on Figure 3 ,like Figure 4 As shown, in the case where the time domain position is determined by the terminal device according to the first preset rule, the above step 301 may specifically include the following step 301D.

[0113] 301D. The terminal device determines the time domain position according to the first preset rule.

[0114] In the case where the time domain position includes the frame where the RSS of the neighboring cell is located, the process of the terminal device determining the time domain position according to the first preset rule is: the terminal device can determine the frame of the RSS of the neighboring cell in the timing of the serving cell based on 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 RSS of the neighboring cell is located, or determine the frame in the timing of the neighboring cell that has the largest overlapping time with the first frame as the frame where the RSS of the neighboring cell is located.

[0115] The process of the terminal device determining the frame that is closest to the first frame or the frame that overlaps with the first frame for the longest time in the timing of the neighboring cell may be as follows: the terminal device first determines the frame that overlaps with the first frame in the timing of the neighboring cell. For these overlapping frames, the terminal device determines the distance between the frame header of each overlapping frame and the frame header of the first frame respectively. Finally, the terminal device determines the overlapping frame corresponding to the minimum distance as the frame that is closest to the first frame or the frame that overlaps with the first frame for the longest time. Of course, the terminal device may also calculate the distance between the frame end of each overlapping frame and the frame end of the first frame, and determine the overlapping frame corresponding to the minimum distance as the frame that is closest to the first frame or the frame that overlaps with the first frame for the longest time.

[0116] In the case where the time domain position includes the subframe where the RSS of the neighboring cell is located, the process for the terminal device to determine the time domain position according to the first preset rule is: the terminal device obtains the configuration of the BL / CE subframe of the serving cell, and determines 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. That is, the terminal device assumes that the configuration of the BL / CE subframe of the neighboring cell is the same as the configuration of the BL / CE subframe of the serving cell. In this case, the terminal device meets the requirement of measuring the RSS of the neighboring cell only when the actual configuration of the BL / CE subframe of the neighboring cell is the same as the assumed configuration.

[0117] In the case where the time domain position includes the frame where the RSS of the neighboring cell is located and the subframe where the RSS of the neighboring cell is located, the process of the terminal device determining the time domain position according to the first preset rule is: 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 RSS of the neighboring cell is located, and determine the BL / CE subframe within the frame where the RSS of the neighboring cell is located that 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.

[0118] Because in the prior art, when a terminal device determines that the time domain position of the 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 the time domain offset, the terminal device determines the neighboring cell's RSS in the first frame of the serving cell's timing, and then determines the frame that overlaps with the first frame in the neighboring cell's timing. In an asynchronous scenario, the terminal device will determine two overlapping frames, and at this time the terminal device cannot determine in which of the two frames the neighboring cell's RSS was sent.

[0119] For example, Figure 5 As shown in FIG, it is assumed that the first frame of the neighboring cell's RSS in the timing of the serving cell is n. In an asynchronous scenario, the terminal device can determine the position of the frame header of the neighboring cell's transmission resource by detecting the primary / secondary synchronization signal (PSS / SSS) of the neighboring cell. In this case, Figure 5 It can be seen that the terminal device determines two frames that overlap with frame n in 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 frame m.

[0120] In addition, since the existing standard stipulates that the starting subframe for sending RSS is the first BL / CE subframe in the frame that sends RSS, but the terminal device can only know the configuration of the BL / CE subframe of the serving cell, it cannot know the configuration of the BL / CE subframe of the neighboring cell, resulting in the inability to determine the subframe position of the neighboring cell RSS in its frame, and thus the inability to measure the RSS of the neighboring cell.

[0121] In the embodiment of the present application, the terminal device can determine the RSS of the neighboring cell in the timing of the neighboring cell through the configuration of the network device or the first preset rule (combined with Figure 5 , the terminal device can determine that the frame where the RSS of the neighboring cell is located in the timing of the neighboring cell is one of frame (m-1) and frame m), or the subframe where the RSS of the neighboring cell is located. Among them, the method of determining the frame or subframe where the RSS of the neighboring cell is located through the configuration of the network device allows each cell to configure a different time domain position of the RSS, thereby increasing network flexibility. The method of determining the frame or subframe where the RSS of the neighboring cell is located through the first preset rule can achieve the determination of the frame or subframe where the RSS of the neighboring cell is located in the neighboring cell timing without adding additional signaling, thereby effectively saving system resources.

[0122] Optionally, in the embodiment of the present application, based on Figure 4 ,like Figure 6 As shown, when the first sequence parameter of the RSS of the neighboring cell is determined by the terminal device according to the configuration device of the network device, the RSS measurement method provided in the embodiment of the present application can also include the following steps 302A, and the above step 302 can specifically include the following steps 302B-302C.

[0123] 302A. The network device sends third RSS configuration information about a neighboring cell to the terminal device.

[0124] Specifically, the network device may first determine third RSS configuration information about the neighboring cell, and then send the third RSS configuration information to the terminal device. The third RSS configuration information carries second information, and the second information is used to indicate a first sequence parameter for determining the RSS of the neighboring cell.

[0125] It is understood that the second information carried in the third RSS configuration information can be obtained by the network device in different ways. For a detailed description of the method for obtaining the second information, reference can be made to the description of the method for obtaining the first information in step 301A above, which will not be repeated in this embodiment of the present application.

[0126] In addition, the second information carried by the third RSS configuration information may be information directly indicating the first sequence parameter. The second information may also be information indirectly indicating the first sequence parameter, that is, the first sequence parameter can only be obtained by deduction based on the second information.

[0127] 302B. The terminal device receives the third RSS configuration information sent by the network device in the serving cell.

[0128] The terminal device may receive third RSS configuration information of a neighboring cell from the network device in the serving cell, where the third RSS configuration information carries second information for indicating a first sequence parameter of the RSS of the neighboring cell.

[0129] 302C. The terminal device determines a first sequence parameter of the RSS of the neighboring cell according to the second information.

[0130] based on Figure 4 ,like Figure 6 As shown, when the first sequence parameter of the RSS of the neighboring cell is determined by the terminal device according to the second preset rule, the above step 302 may specifically include the following step 302D.

[0131] 302D. The terminal device determines a first sequence parameter of the RSS of the neighboring cell according to a second preset rule.

[0132] 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 of the RSS of the neighboring cell is the same as the value of u of the RSS of the serving cell. In this case, the terminal device meets the requirement of measuring the RSS of the neighboring cell only when the actual value of the first sequence parameter of the RSS of the neighboring cell is the same as the assumed value.

[0133] Since the terminal device cannot obtain the first sequence parameter of the RSS of the neighboring cell, it cannot correctly generate the sequence of the RSS of the neighboring cell, thereby failing to measure the RSS of the neighboring cell.

[0134] In an embodiment of the present application, a terminal device can determine the first sequence parameter of the RSS of a neighboring cell through the configuration of a network device or a second preset rule. Determining the first sequence parameter of the RSS of a neighboring cell through the configuration of a network device ensures that, even when different cells are configured with different first sequence parameters of the RSS, the terminal device can still correctly measure the RSS of the neighboring cell. Determining the first sequence parameter of the RSS of a neighboring cell through the second preset rule can clarify the value of the first sequence parameter without adding additional signaling.

[0135] Optionally, in an embodiment of the present application, after executing step 303 above, the terminal device may obtain a first RSRP of the neighboring cell based on the measurement result of the RSS of the neighboring cell. The terminal device may measure the RSS of the serving cell based on the time domain position of the RSS of the serving cell in the timing of the serving cell and the first sequence parameter of the RSS of the serving cell, and obtain a second RSRP of the serving cell based on the measurement result of the RSS of the serving cell. Thereafter, the terminal device may perform cell reselection or measurement reporting based on the first RSRP and the second RSRP.

[0136] The terminal can obtain the RSRP and reference signal received quality (RSRQ) of the cell by measuring the CRS of the cell, and then perform cell reselection or measurement reporting based on the RSRP and RSRQ of the neighboring cell and the RSRP and RSRQ of the serving cell. When certain conditions are met, the cell measurement is based on the RSS. In this case, the cell reselection or measurement reporting can be based only on the RSRP, and the effect of measuring RSRP based on the RSS is better than that of measuring RSRP based on the CRS.

[0137] It should be noted that the triggering conditions for executing the RSS measurement method of the embodiment of the present application 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 the second RSS configuration information about the neighboring cell sent by the network device. In the embodiment of the present application, the terminal device triggers the execution of the RSS measurement method only when it receives the second RSS configuration information about the neighboring cell sent by the network device and determines that RSRQ in the measurement reporting configuration sent by the network device is not configured as the reference value for measurement reporting.

[0138] Optionally, in an embodiment of the present application, when the terminal device determines the frame of the neighboring cell's RSS in the timing of the serving cell, that is, when determining 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, and then use the target value to perform a modulo operation on the period of the neighboring cell's RSS, and finally determine the result of the modulo operation as the frame number of the first frame. This overcomes the problem that the frame number directly calculated may exceed the range of the period of the neighboring cell's RSS when the modulo operation is not performed. For example, assuming that the period of the neighboring cell's RSS is 160 milliseconds, that is, 16 frames, then the range of the frame number calculated by the terminal device should be between [0, 1, 2, 3, 4...15]. However, when the modulo operation is not performed, the frame number directly calculated may be greater than 15. By performing a modulo operation, the embodiment of the present application effectively avoids the problem that the calculated frame number exceeds the range of the period of the neighboring cell's RSS.

[0139] It can be understood that the period of the RSS of the neighboring cell is in frames, which is obtained by dividing the period of the RSS of the neighboring cell (in milliseconds) by 10 (10 means that one frame is 10 milliseconds).

[0140] 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 information, for example, the same RSS configuration information, or different information.

[0141] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of method. In order to realize the above functions, it includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily appreciate that, in combination with the algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in a hardware or computer software driven hardware manner depends on the specific application and design constraints of the technical solution.
