Description

[0001] This application is a divisional application. The application number of the original application is 201910365273.9, and the original application date is April 30, 2019. The entire content of the original application is incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0003] CLI measurement on the terminal device side was introduced in the new radio (NR) work item (WI) remote interference mitigation (RIM) / cross link interference (CLI) of version (Rel)-16. It is mainly used to evaluate the interference level of the uplink transmission of the terminal device of the neighboring cell on the terminal device of the serving cell receiving the downlink data of the serving cell when using dynamic uplink and downlink matching. CLI measurement can include two measurements: sounding reference signal (SRS)-reference signal received power (RSRP), and CLI-received signal strength indicator (RSSI). Among them, SRS-RSRP is the RSRP measurement of the SRS of the terminal device from the neighboring cell, and CLI-RSSI is the RSSI measurement from the specified time-frequency resources. Among them, the timing of CLI measurement is determined by the implementation of the terminal device according to the conclusion of RAN1.

[0004] Currently, technical specification (TS) 38.133 defines scheduling restrictions for radio resource management (RRM) measurements due to mixed subcarrier spacing and beam scanning. Mixed subcarrier spacing refers to the difference between the subcarrier spacing of the synchronization signal and physical broadcast channel block (SSB) and the subcarrier spacing of data. Scheduling restrictions occur when the terminal device does not support simultaneous reception of two different subcarrier spacings. Beam scanning causes scheduling restrictions because the beam used by the terminal device during measurement is different from the beam used when receiving data from the serving cell. Therefore, the terminal device cannot transmit data with the serving cell during measurement. The so-called scheduling restriction means that the terminal device may not receive data on specified symbols.

[0005] Current RRM measurements are based on the terminal device's downlink timing, but CLI measurements are based on the terminal device's self-determined timing, which is typically ahead of the terminal device's downlink timing. Therefore, existing scheduling restrictions for RRM measurements do not apply to CLI measurements. It is currently unclear which symbols the terminal device will be subject to scheduling restrictions for when performing CLI measurements. Summary of the Invention

[0006] The embodiments of the present application provide a communication method and device for clarifying the scheduling restrictions generated by a terminal device when performing CLI measurement.

[0007] In a first aspect, a first communication method is provided, which includes: a terminal device determines whether the terminal device supports sending and receiving signals other than a first reference signal during a measurement process, and the first reference signal is used by the terminal device to perform measurement during the measurement process; when the terminal device does not support sending and receiving signals other than the first reference signal during the measurement process, the terminal device only receives the first reference signal within a first time domain range, and the first time domain range includes a first time domain symbol and a second time domain symbol, the first time domain symbol is a time domain symbol configured by a network device, and the second time domain symbol includes N time domain symbols before the first time domain symbol and / or N time domain symbols after the first time domain symbol, and N is a positive integer.

[0008] The method may be performed by a first communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip system.

[0009] In an embodiment of the present application, a terminal device may determine whether the terminal device supports the transmission and reception of signals other than the first reference signal during the measurement process. If the terminal device determines that the terminal device does not support the transmission and reception of signals other than the first reference signal during the measurement process, the terminal device may only receive the first reference signal within the first time domain range. Receiving only the first reference signal within the first time domain range can be understood as the terminal device only receiving the first reference signal within the first time domain range, not receiving signals other than the first reference signal, and not sending any signals. Similarly, the network device may only send the first reference signal to the terminal device within the first time domain range. Of course, it may also not send the first reference signal to the terminal device, but not send signals other than the first reference signal to the terminal device, nor receive any signals from the terminal device. In other words, if the terminal device's measurement of the first reference signal affects the transmission and reception of signals, the terminal device and the network device can both determine the scheduling restrictions of the terminal device when performing the measurement, so that the terminal device may not receive signals other than the first reference signal or send any signals on time domain symbols with scheduling restrictions, so as to minimize interference with the transmission and reception of other signals due to the measurement.

[0010] In combination with the first aspect, in a possible implementation of the first aspect, the value of N is a predefined value; or, the value of N is determined according to the subcarrier spacing of the service cell of the terminal device; or, the value of N is determined according to the frequency range to which the frequency of the service cell of the terminal device belongs; or, the value of N is determined according to the timing advance of the terminal device in the service cell; or, the value of N is determined according to the maximum value of the timing advance measured by the terminal device for the first reference signal.

[0011] There are multiple possible ways to determine the value of N. The specific method can be configured by the network device or specified by the protocol, which is relatively flexible.

[0012] In combination with the first aspect, in a possible implementation of the first aspect, the method further includes: the terminal device receiving a first message from the network device, where the first message is used to indicate a value of N.

[0013] The value of N can be determined by the network device, and the network device can inform the terminal device after determination, so that the terminal device does not need to determine the value of N again, which can make the terminal device and the network device consistent in the value of N and reduce the workload of the terminal device.

[0014] In combination with the first aspect, in a possible implementation of the first aspect, the method further includes: the terminal device sending a second message to the network device, where the second message is used to indicate the value of N.

[0015] The value of N can also be determined by the terminal device, and the terminal device can inform the network device after determination, so that the network device no longer needs to determine the value of N. This can make the terminal device and the network device consistent in the value of N and reduce the workload of the network device.

[0016] In combination with the first aspect, in a possible implementation of the first aspect, the method further includes: the terminal device sends a second message to the network device, where the second message is used to indicate the maximum value of the timing advance when the terminal device measures the first reference signal.

[0017] The terminal device does not need to send a specific value of N to the network device, but only indicates to the network device the maximum value of the timing advance when the terminal device measures the first reference signal. The network device can determine the value of N based on the maximum value of the timing advance when the terminal device measures the first reference signal.

[0018] In combination with the first aspect, in a possible implementation of the first aspect, the method also includes: when the terminal device determines that the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, and the terminal device determines that the beam scanning method is not adopted during the measurement process, the terminal device receives the first reference signal within the first time domain range, and sends and / or receives a first signal, where the first signal is a signal other than the first reference signal.

[0019] If the terminal device determines that the beam scanning method is not used when measuring the first reference signal, then the receiving beam used by the terminal device when performing the measurement and the receiving beam used when receiving the downlink data of the service cell can be the same. Therefore, if the terminal device determines that the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, the terminal device can receive not only the first reference signal within the first time domain, but also other signals except the first reference signal, and can also send any signal. For the network device, it can also send not only the first reference signal within the first time domain, but also any signal from the terminal device, and can also send other signals except the first reference signal to the terminal device. Because the measurement process will not affect other signal receiving and sending processes, or has little impact on other signal receiving and sending processes, the measurement process and other signal receiving and sending processes can be performed synchronously to improve communication efficiency.

[0020] In combination with the first aspect, in a possible implementation of the first aspect, the method also includes: when the terminal device determines that the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, and the terminal device determines to use a beam scanning method during the measurement process, the terminal device only receives the first reference signal within the first time domain range.

[0021] If the terminal device determines that the beam scanning method is not used when measuring the first reference signal, then the receiving beam used by the terminal device when performing the measurement and the receiving beam used when receiving the downlink data of the service cell may be different. In this case, during the measurement process, the terminal device cannot receive the downlink signal from the service cell. Therefore, even if the terminal device determines that the terminal device supports the transmission and reception of other signals in addition to the first reference signal during the measurement process, the terminal device can only receive the first reference signal within the first time domain. It can be understood that the terminal device only receives the first reference signal within the first time domain, does not receive other signals except the first reference signal, and does not send any signals. Similarly, the network device can only send the first reference signal to the terminal device within the first time domain. Of course, it can also not send the first reference signal to the terminal device, but does not send other signals except the first reference signal to the terminal device, nor does it receive any signals from the terminal device. In this way, interference with the reception and transmission of other signals due to measurement can be avoided as much as possible.

[0022] In combination with the first aspect, in a possible implementation of the first aspect, the method further includes: the terminal device sends capability information of the terminal device to the network device, and the capability information is used to indicate whether the terminal device supports sending and receiving other signals other than the first reference signal during the measurement process.

[0023] The terminal device may send the capability information of the terminal device to the network device, so that the network device may determine, based on the capability information of the terminal device, whether the terminal device supports transmitting and receiving signals other than the first reference signal during the measurement process. Of course, the network device may also determine whether the terminal device supports transmitting and receiving signals other than the first reference signal during the measurement process based on other factors, and the specific factors are not limited thereto.

[0024] According to a second aspect, a second communication method is provided, which includes: a network device determines whether a terminal device supports sending and receiving signals other than a first reference signal during a measurement process, and the first reference signal is used by the terminal device to perform measurements during the measurement process; when it is determined that the terminal device does not support sending and receiving signals other than the first reference signal during the measurement process, the network device does not send signals other than the first reference signal to the terminal device within a first time domain range, and the first time domain range includes a first time domain symbol and a second time domain symbol, the first time domain symbol is a time domain symbol configured by the network device, and the second time domain symbol includes N time domain symbols before the first time domain symbol and / or N time domain symbols after the first time domain symbol, and N is a positive integer.

[0025] The method may be performed by a second communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip system.

[0026] In combination with the second aspect, in a possible implementation of the second aspect, the value of N is a predefined value; or, the value of N is determined according to the subcarrier spacing of the service cell of the terminal device; or, the value of N is determined according to the frequency range to which the frequency of the service cell of the terminal device belongs; or, the value of N is determined according to the timing advance of the terminal device in the service cell of the terminal device; or, the value of N is determined according to the maximum value of the timing advance of the terminal device when measuring the first reference signal.

[0027] In combination with the second aspect, in a possible implementation of the second aspect, the method further includes: the network device receiving a second message from the terminal device, where the second message is used to indicate a value of N.

[0028] In combination with the second aspect, in a possible implementation of the second aspect, the method further includes: the network device sending a first message to the terminal device, where the first message is used to indicate a value of N.

[0029] In combination with the second aspect, in a possible implementation of the second aspect, the method further includes: the network device sends a first message to the terminal device, where the first message is used to indicate the maximum value of the timing advance of the terminal device when measuring the first reference signal.

[0030] In combination with the second aspect, in a possible implementation of the second aspect, the method also includes: when the network device determines that the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, and the network device determines that the terminal device does not adopt the beam scanning method during the measurement process, the network device sends the first reference signal to the terminal device within the first time domain range, and receives and / or sends a first signal to the terminal device, where the first signal is a signal other than the first reference signal.

[0031] In combination with the second aspect, in a possible implementation of the second aspect, the method also includes: when the network device determines that the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, and the network device determines that the terminal device adopts a beam scanning method during the measurement process, the network device only sends the first reference signal within the first time domain range.

[0032] In combination with the second aspect, in a possible implementation of the second aspect, the network device determines whether the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, including: the network device receives capability information of the terminal device from the terminal device, and the network device determines whether the terminal device supports sending and receiving signals other than the first reference signal during the measurement process based on the capability information.

[0034] According to a third aspect, a third communication method is provided, which includes: a terminal device receives measurement configuration information from a network device, the measurement configuration information being used to instruct the terminal device to measure multiple first reference signals; when the terminal device determines that the minimum value of the difference between two of the multiple cyclic shifts corresponding to the multiple first reference signals is greater than or equal to M, the terminal device measures the multiple first reference signals according to the measurement configuration information; wherein the multiple first reference signals are first reference signals located on the same time domain symbol and corresponding to the same comb structure.

[0035] The method may be performed by a third communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip system.

[0036] If the minimum difference of the cyclic shift is not restricted, the terminal device can only detect according to the worst case, that is, the detection window corresponding to each cyclic shift is the time resolution of a single cyclic shift (the minimum is 1 / 48 of the time domain symbol). This may cause the terminal device to miss or misdetect the first reference signal, thereby reducing the accuracy of the measurement. However, the method provided in the embodiment of the present application defines the minimum distance between the cyclic shifts of multiple first reference signals on the same comb of the same time domain symbol. The terminal device can adjust the size of the detection window corresponding to each cyclic shift accordingly during detection, so that the measured first reference signal can fall into the corresponding detection window as much as possible, thereby improving the accuracy of the measurement.

[0037] In combination with the third aspect, in a possible implementation of the third aspect, the value of M is a predefined value; or, the value of M is determined according to the maximum timing error that the terminal device can handle; or, the value of M is determined according to the frequency range to which the frequency of the service cell of the terminal device belongs; or, the value of M is determined according to the subcarrier spacing of the service cell of the terminal device.

[0038] The value of M can also be determined by the terminal device, and the terminal device can inform the network device after determination, so that the network device does not need to determine the value of M again, which can make the terminal device and the network device consistent in the value of M and reduce the workload of the network device.

[0039] In combination with the third aspect, in a possible implementation of the third aspect, the method further includes: the terminal device receives a first message from a network device, where the first message is used to indicate a value of M.

[0040] The terminal device can determine the value of M by itself according to one of the above methods, or the value of M can also be determined by the network device. After determination, the network device can send the value of M to the terminal device, thereby eliminating the need for the terminal device to determine the value of M.

[0041] In a fourth aspect, a fourth communication method is provided, which includes: a network device determines measurement configuration information, wherein the measurement configuration information is used to instruct a terminal device to measure multiple first reference signals, and the minimum value of the difference between each of the multiple cyclic shifts corresponding to the multiple first reference signals configured by the network device is greater than or equal to M, and the multiple first reference signals are first reference signals located on the same time domain symbol and corresponding to the same comb structure; the network device sends the measurement configuration information to the terminal device.

[0042] The method may be performed by a fourth communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip system.

[0044] In combination with the fourth aspect, in a possible implementation of the fourth aspect, the method further includes: the network device sending a first message to the terminal device, where the first message is used to indicate a value of M.

[0047] The method may be performed by a fifth communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip system.

[0048] Through the method provided in the embodiment of the present application, no two first reference signals among the multiple first reference signals configured by the network device are located in the same time domain symbol and correspond to the same comb. This is equivalent to fundamentally solving the cause of the problem of false detection or missed detection of reference signals by the terminal device, and helps to improve the measurement accuracy of the terminal device.

[0049] In combination with the fifth aspect, in a possible implementation of the fifth aspect, the measurement configuration information is further used to instruct the terminal device to measure multiple second reference signals, where the multiple second reference signals are located on the same time domain symbol and correspond to the same comb structure.

[0050] If the measurement configuration information also instructs the terminal device to measure multiple second reference signals, and the multiple second reference signals are located on the same time domain symbol and correspond to the same comb structure, then the terminal device may not measure multiple second reference signals to avoid problems such as false detection or missed detection that may occur during the measurement process.

The RSU may be a fixed infrastructure entity that supports vehicle-to-everything (V2X) applications and may exchange messages with other entities that support V2X applications. The access network equipment may also coordinate attribute management of the air interface. For example, the access network device may include an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in a long term evolution (LTE) system or long term evolution-advanced (LTE-A), or may also include a next generation node B (next generation node B, gNB) in a fifth generation mobile communication technology (5G) new radio (NR) system, or may also include a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (Cloud RAN) system, and the embodiments of the present application are not limited.

[0175] Of course, network equipment can also include core network equipment, but because the technical solutions provided in the embodiments of this application mainly involve access network equipment, in the following text, unless otherwise specified, the "network equipment" described below refers to access network equipment.

[0176] 3) RRM measurements are measurements performed by terminal devices to support radio resource management and mobility management. The measurement targets, measurement quantities, and corresponding reporting criteria are generally configured by the network. Common RRM measurements include synchronization signal (SS) RSRP measurements or SS reference signal received quality (RSRQ). Terminal devices can perform measurements based on the network device's configuration and report the measurement results to the network device.

[0177] 4) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0178] Furthermore, unless otherwise indicated, ordinal numbers such as "first" and "second" in the embodiments of this application are used to distinguish multiple objects and are not used to define the order, timing, priority, or importance of multiple objects. For example, the first identifier and the second identifier are only used to distinguish different identifiers and do not indicate differences in the content, priority, or importance of the two identifiers.

[0179] The above introduces some concepts involved in the embodiments of the present application. The following introduces the technical features of the embodiments of the present application.

[0180] The CLI measurement on the terminal device side was introduced in the NR WI RIM / CLI of Rel-16. It is mainly used to evaluate the interference level of the uplink transmission of the terminal device in the neighboring cell on the downlink data received by the terminal device in the serving cell when a dynamic uplink and downlink ratio is used. CLI measurement can include two measurements: SRS-RSRP and CLI-RSSI. Among them, SRS-RSRP is the RSRP measurement of the SRS from the terminal device in the neighboring cell, and CLI-RSSI is the RSSI measurement from the specified time-frequency resources. The reference signal can be SRS or other reference signals.

[0181] For reference Figure 1 , which is a schematic diagram of a CLI measurement scenario. Figure 1 The system includes network device 1, network device 2, terminal device 1, and terminal device 2, wherein terminal device 1 is distributed in cell 1 provided by network device 1, and terminal device 2 is distributed in cell 2 provided by network device 2. At certain moments, terminal device 2 sends an SRS, or sends an uplink control channel or an uplink data channel to cell 2, and terminal device 1 receives a downlink control channel or a downlink data channel from network device 1. Since cell 2 and cell 1 are adjacent cells, the uplink information (SRS, uplink control channel, or uplink data channel) sent by terminal device 2 may also be received by terminal device 1, thereby interfering with the reception process of terminal device 1. Therefore, network device 1 can configure terminal device 1 to measure the RSRP or RSSI of the SRS from terminal device 2 (or, from other devices in cell 2, or from terminal device 2 and other devices in cell 2, or, from terminal device 2 and devices in other cells, or, from devices in other cells, or, from other devices in cell 2 and devices in other cells, or, from terminal device 2, other devices in cell 2 and devices in other cells), so as to determine the interference level, and make corresponding scheduling decisions or cooperate with network device 2 based on the interference level.

[0182] certainly, Figure 1 This example assumes two cells are provided by different network devices. Alternatively, cell 1, where terminal device 1 is located, and cell 2, where terminal device 2 is located, may be provided by the same network device, but cells 1 and 2 are adjacent. In this case, the SRS transmitted by terminal device 2 may also be received by terminal device 1, causing interference to terminal device 1's transmission and reception. In this case, terminal device 1 can also measure the RSRP or RSSI of the SRS transmitted by terminal device 2 to determine the interference level.

[0183] Regarding the measurement configuration of SRS-RSRP, according to RAN1's ​​conclusion, it is the same as the configuration for configuring the terminal device to transmit SRS. This measurement configuration may include SRS time-frequency resource information, comb structure (comb) information, SRS root sequence and cyclic shift, etc. Comb means, for example, a resource block (RB) includes 12 subcarriers in the frequency domain, and SRS may not be transmitted on every subcarrier. For example, SRS may be transmitted on every other subcarrier. This frequency domain distribution of SRS can be called comb. Currently, there are two main types of comb, and the corresponding values ​​are comb=2 and comb=4. If comb=2, it means that the corresponding reference signal will be transmitted on every 2 subcarriers in the frequency domain, and if comb=4, it means that the corresponding reference signal will be transmitted on every 4 subcarriers in the frequency domain.

[0184] Regarding CLI measurement timing, according to RAN1, it's determined by the terminal device's implementation. CLI measurement timing refers to when the terminal device detects the reference signal used for CLI measurements. The reference signal used for CLI measurements is transmitted by the terminal device in the neighboring cell. Therefore, the CLI measurement timing is generally advanced relative to the terminal device's downlink timing in the serving cell.

[0185] Current RRM measurements are based on the downlink timing of the terminal device in the serving cell, where the downlink timing of the terminal device in the serving cell refers to the moment when the terminal device receives the downlink signal in the serving cell. However, CLI measurements are based on the timing determined by the terminal device itself, which is generally ahead of the downlink timing of the terminal device. Therefore, the scheduling restrictions of existing RRM measurements cannot be applied to CLI measurements. It is currently unclear on which symbols the terminal device will generate scheduling restrictions when performing CLI measurements.

[0186] Currently, TS 38.133 defines scheduling restrictions for RRM measurements due to mixed subcarrier spacing and receiving beam scanning. Mixed subcarrier spacing refers to the difference between the subcarrier spacing of the SSB and the subcarrier spacing of the data. Scheduling restrictions occur when the terminal device does not support simultaneous reception of two different subcarrier spacings. The reason why receiving beam scanning causes scheduling restrictions is that the receiving beam used by the terminal device during measurement is different from the receiving beam used when receiving data from the serving cell. Therefore, the terminal device cannot transmit data with the serving cell during measurement. The so-called scheduling restriction means that the terminal device may not receive data on a specified symbol.

[0187] In view of this, a technical solution of an embodiment of the present application is provided. In an embodiment of the present application, a terminal device can determine whether the terminal device supports receiving and transmitting signals other than the first reference signal during the measurement process. If the terminal device determines that the terminal device does not support receiving and transmitting signals other than the first reference signal during the measurement process, the terminal device can only receive the first reference signal within the first time domain range. Receiving only the first reference signal within the first time domain range can be understood as the terminal device only receiving the first reference signal within the first time domain range, not receiving other signals except the first reference signal, and not sending any signals. In other words, if the terminal device believes that the measurement of the first reference signal will affect the reception and transmission of the signal, the terminal device can determine the scheduling restrictions of the terminal device when performing the measurement, so that it can not receive other signals except the first reference signal on the time domain symbols with scheduling restrictions, and not send any signals. Clarifying the scheduling restrictions can minimize the failure of receiving and transmitting other signals caused by the terminal device being unable to receive and transmit the first reference signal and other signals at the same time, and the resulting waste of network resources.

[0188] Please refer to Figure 2 , which is an application scenario of an embodiment of the present application. Figure 2 It includes network equipment and terminal equipment, and the terminal equipment is connected to the network equipment. Figure 2 The number of terminal devices in the example is just an example. In actual applications, the network device can provide services for multiple terminal devices. The network device, as well as all or part of the multiple terminal devices, can use the method provided in the embodiment of the present application to determine the scheduling restrictions. In addition, Figure 2 The terminal device in the service cell needs to measure the reference signal from the terminal device in the neighboring cell of the service cell where the terminal device is located, but Figure 2 The neighboring area of ​​the service cell where the terminal device is located is not drawn, nor is the terminal device in the neighboring area. The neighboring area of ​​the service cell where the terminal device is located can belong to the same network device as the service cell, that is, Figure 2 or, the neighboring area of ​​the serving cell where the terminal device is located may belong to a different network device than the serving cell, for example, the serving cell belongs to Figure 2 The network equipment in the service cell can belong to Figure 2 Another network device not shown.

[0189] Figure 2The network device in the present invention is, for example, an access network device, such as a base station. The network device corresponds to different devices in different systems. For example, in a fourth-generation mobile communication technology (4G) system, it may correspond to an eNB, and in a 5G system, it may correspond to a gNB. If the embodiments of the present application are applied to future communication systems, the network device may correspond to an access network device in the future communication system.

[0190] The following describes the technical solutions provided by the embodiments of the present application in conjunction with the accompanying drawings. In the embodiments of the present application, the concepts of "carrier" and "cell" can be interchanged.

[0191] This application embodiment provides a first communication method, see Figure 3 , which is the flow chart of this method. In the following introduction, this method is applied to Figure 2 Take the network architecture shown as an example. In addition, the method can be performed by two communication devices, such as a first communication device and a second communication device, wherein the first communication device can be a network device or a communication device that can support the network device to implement the functions required by the method, or the first communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required by the method, of course, it can also be other communication devices, such as a chip system. The same is true for the second communication device. The second communication device can be a network device or a communication device that can support the network device to implement the functions required by the method, or the second communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required by the method, of course, it can also be other communication devices, such as a chip system. There is no restriction on the implementation methods of the first communication device and the second communication device, for example, the first communication device can be a network device, the second communication device is a terminal device, or the first communication device and the second communication device are both network devices, or the first communication device and the second communication device are both terminal devices, or the first communication device is a network device, and the second communication device is a communication device that can support the terminal device to implement the functions required by the method, and so on. Wherein, the network device is, for example, a base station.

[0192] For the sake of convenience, the following takes the method executed by the network device and the terminal device as an example, that is, the first communication device is the network device and the second communication device is the terminal device as an example. Figure 2 The network architecture shown, therefore, the network devices described below can be Figure 2 The network devices in the network architecture shown in the figure, the terminal devices described below can be Figure 2 The other devices described below may be terminal devices, such as Figure 2The terminal device in the neighboring area of ​​the service cell of the terminal device shown in , or it can also be a network device, such as Figure 2 Other network devices not shown in the figure. The neighboring area of ​​the serving cell can be Figure 2 The network equipment shown is provided, or it can be Figure 2 Provided by another network device not shown.

[0193] S31. The terminal device determines whether the terminal device supports sending and receiving signals other than a first reference signal during a measurement process, where the first reference signal is used by the terminal device to perform measurement during the measurement process.

[0194] The first reference signal may be a reference signal used by the terminal device to perform measurements, and the first reference signal may be, for example, an SRS, or may be other reference signals, such as a channel state information reference signal (CSI-RS), etc., without specific limitation. There may be multiple reference signals, but only the reference signal used by the terminal device in the embodiment of the present application to perform measurements is called the first reference signal. Correspondingly, it can be understood that the measurement process described in the embodiment of the present application is a measurement process corresponding to the first reference signal, or in other words, in the measurement process, the terminal device needs to measure the first reference signal. For example, the network device configures the terminal device to measure reference signal 1, and the terminal device may receive reference signal 1 and reference signal 2, but the network device does not configure the terminal device to measure reference signal 2, then reference signal 1 is the first reference signal, and reference signal 2 is not the first reference signal.

[0195] The other device that sends the first reference signal may be referred to as a first device. The first device may be a terminal device, or a network device, etc. There is no limitation on the type of the first device.

[0196] For a terminal device, the capability information of the terminal device can be determined. The capability information of the terminal device can indicate multiple capabilities of the terminal device. The capability information of the terminal device concerned in the embodiments of the present application is the ability to indicate whether the terminal device supports the transmission and reception of signals other than the first reference signal during the measurement process. Thus, the terminal device can determine whether the terminal device supports the transmission and reception of signals other than the first reference signal during the measurement process, or whether the terminal device does not support the transmission and reception of signals other than the first reference signal during the measurement process. As to whether the terminal device also determines other capability information of the terminal device, the embodiments of the present application do not impose any restriction.

[0197] For example, if the terminal device is affected by the measurement process or is greatly affected by the measurement process when sending and receiving signals other than the first reference signal during the measurement process, the capability information may indicate that the terminal device does not support sending and receiving signals other than the first reference signal during the measurement process. The measurement process here may refer to CLI measurement, or it may be other measurement processes. In addition, sending and receiving signals other than the first reference signal during the measurement process may be understood as receiving signals other than the first reference signal during the measurement process, or sending any signal (including the first reference signal and other signals) during the measurement process, or receiving signals other than the first reference signal during the measurement process, and sending any signal during the measurement process.

[0198] Other signals other than the first reference signal may include control signals, such as a physical uplink control channel (PUCCH) or a physical downlink control channel (PDCCH), or data signals, such as a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH), or control signals and data signals, etc., without specific limitation.

[0199] S32: The network device determines whether the terminal device supports sending and receiving signals other than the first reference signal during the measurement process.

[0200] For example, after the terminal device determines the capability information of the terminal device, it can send the capability information to the network device. After receiving the capability information from the terminal device, the network device can determine whether the terminal device supports sending and receiving other signals in addition to the first reference signal during the measurement process based on the capability information. Figure 3 In S34, the terminal device sends capability information of the terminal device to the network device, and the network device receives the capability information from the terminal device. The capability information may indicate whether the terminal device supports sending and receiving signals other than the first reference signal during the measurement process. S34 may occur before S32 and after S31.

[0201] Similarly, the capability information sent by the terminal device to the network device may be information indicating whether the terminal device supports the ability to transmit and receive signals other than the first reference signal during the measurement process. Whether the terminal device also sends other capability information of the terminal device to the network device is not limited in this embodiment of the present application.

[0202] S33. When it is determined that the terminal device does not support transmitting or receiving signals other than the first reference signal during the measurement process, the network device transmits only the first reference signal within a first time domain range, and the terminal device receives only the first reference signal within the first time domain range, where the first time domain range includes a first time domain symbol and a second time domain symbol, where the first time domain symbol is a time domain symbol configured by the network device, and the second time domain symbol includes N time domain symbols preceding the first time domain symbol and / or N time domain symbols following the first time domain symbol. N may be a positive integer.

[0203] Before S32 and after S31, or before S31, the network device may further configure the terminal device to perform measurement, such as configuring the terminal device to perform SRS-RSRP measurement, or configuring the terminal device to perform CLI-RSSI measurement, or may further configure the terminal device to perform other measurements. The network device may also configure a time domain symbol for the terminal device to perform measurement. The time domain symbol where the first reference signal configured by the network device for the terminal device to perform measurement is located is the first time domain symbol.

[0204] The terminal device can perform measurements according to the configuration of the network device. If the network device determines that the terminal device does not support the sending and receiving of signals other than the first reference signal during the measurement process, the network device may not send other signals except the first reference signal to the terminal device within the first time domain. It can be understood that the network device can send the first reference signal for measurement to the terminal device within the first time domain (or may not send the first reference signal), and may also send other signals except the first reference signal to the terminal device, but for signals other than the first reference signal, the network device does not expect the terminal device to receive them correctly, and the network device does not expect the terminal device to send any signals within the first time domain. Since the network device does not expect the terminal device to send any signals within the first time domain, one implementation of the network device is that the network device may not detect (or describe as, receive) any signals from the terminal device within the first time domain.

[0205] Alternatively, if the network device determines that the terminal device does not support the transmission and reception of signals other than the first reference signal during the measurement process, then since the network device does not expect the terminal device to correctly receive signals other than the first reference signal, the network device may send the first reference signal for measurement to the terminal device within the first time domain (or may not send the first reference signal), but may not send signals other than the first reference signal to the terminal device within the first time domain, and the network device does not expect the terminal device to send any signals within the first time domain. Since the network device does not expect the terminal device to send any signals within the first time domain, one implementation of the network device is that the network device may not detect (or be described as receiving) any signals from the terminal device within the first time domain.

[0206] If the terminal device determines that the terminal device does not support the transmission and reception of signals other than the first reference signal during the measurement process, the terminal device only receives the first reference signal within the first time domain range. This can be understood as the terminal device only receiving the first reference signal within the first time domain range, not receiving signals other than the first reference signal, and not sending any signals. Or it can also be described as the terminal device not expecting to receive or send signals other than the first reference signal within the first time domain range. Among them, because the terminal device is to perform measurements within the first time domain range, it can only receive the first reference signal used for measurement, such as SRS, within the first time domain range, and not receive signals other than the first reference signal, nor send any signals, so as to avoid the signal reception and transmission process being affected by the measurement process.

[0207] The first time domain symbol is the symbol of the first reference signal that the network device configures the terminal device to measure, or in other words, the first time domain symbol is the time domain symbol of the first reference signal from other devices that the network device configures the terminal device to measure, that is, the first time domain symbol is the time domain symbol used by the terminal device configured by the network device to perform measurement.

[0208] The first time domain symbol may include one time domain symbol or multiple time domain symbols, which is related to the number of time domain symbols occupied by the terminal device configured by the network device for measurement. The measurement described herein may be, for example, a CLI measurement, or may be other measurements. The time domain symbol may be, for example, an orthogonal frequency division multiplexing (OFDM) symbol.

[0209] The following describes how the network device configures the first time domain symbol, taking the CLI measurement as an example. If the measurement is a CLI measurement, the first reference signal is sent by another terminal device. The network device can obtain information such as the uplink and downlink ratios and reference signal transmission configuration of the cell where the other terminal device is located, and thereby determine the time domain symbol at which the terminal device in the other cell sends the first reference signal based on this information. The network device can determine the time domain symbol at which the terminal device in the other cell sends the first reference signal as the first time domain symbol. Alternatively, if the network device cannot obtain information such as the uplink and downlink ratios or reference signal transmission configuration of the cell where the other terminal device is located, or if the information obtained by the network device is not accurate enough, the network device can configure the terminal device to receive the first reference signal from the other terminal device on multiple time domain symbols. In other words, in this case, the first time domain symbol may include more time domain symbols. After configuring the first time domain symbol, the network device can send information about the first time domain symbol to the terminal device. After receiving the information about the first time domain symbol, the terminal device can determine the first time domain range based on the first time domain symbol and taking into account the timing of the other terminal devices. For example, if another terminal device is farther away from the terminal device and has a longer timing, the terminal device may determine that it needs to start detecting the first reference signal from the other terminal device N time domain symbols prior to the first time domain symbol, where N is, for example, the number of time domain symbols corresponding to the timing of the other terminal device. In other words, the terminal device will detect the first reference signal from the other terminal device within the first time domain range.

[0210] According to the introduction in the previous paragraph, although the network device configures the terminal device to perform measurements in the first time domain symbol, the other device sending the first reference signal may be a terminal device in a neighboring area, or may be other network devices, etc., resulting in different measurement timings, for example, it may be ahead of the first time domain symbol configured by the network device. Therefore, when the terminal device performs measurements, it may actually measure within the first time domain range. The first time domain range includes the first time domain symbol, or includes the second time domain symbol, or includes the first time domain symbol and the second time domain symbol. The second time domain symbol may include one time domain symbol or multiple time domain symbols.

[0211] Among them, if the first time domain range only includes the first time domain symbol, it indicates that the terminal device is actually performing measurements on the first time domain symbol configured by the network device; or, if the first time domain range only includes the second time domain symbol, it indicates that the terminal device is actually performing measurements on the second time domain symbol; or, if the first time domain range includes the first time domain symbol and the second time domain symbol, it indicates that the terminal device is actually performing measurements on the first time domain symbol and the second time domain symbol.

[0212] Therefore, as stated in S33, the first time domain symbol is the time domain symbol where the first reference signal is located, which means that the first time domain symbol is the time domain symbol that the network device configures the terminal device to measure the first reference signal, and the time domain symbol that the terminal device actually measures the first reference signal is the time domain symbol included in the first time domain range.

[0213] It should be noted that the first time domain symbol is a symbol configured by the network device for measurement. In a scenario where the terminal device measures the first reference signal, the first reference signal is sent by the transmitter on the first time domain symbol. In other possible scenarios, the network device can configure the first time domain symbol, but the first reference signal for measurement may not exist on the first time domain symbol, and the terminal device does not perform measurement.

[0214] Although the network device configures the terminal device to perform measurements in the first time domain symbol, since the other device sending the first reference signal may be a terminal device in a neighboring area, or may be other network devices, etc., it generally causes the measurement timing to be advanced relative to the downlink timing of the terminal device in the serving cell. Therefore, the second time domain symbol may include the N time domain symbols before the first time domain symbol. Of course, to be on the safe side, the second time domain symbol may also include the N time domain symbols after the first time domain symbol, or include the N time domain symbols before the first time domain symbol, and the N time domain symbols after the first time domain symbol. In this way, the scheduling restrictions are also clarified.

[0215] The value of N can be determined by the network device, and the network device can tell the terminal device after the determination. For example, the network device determines the value of N and sends a first message to the terminal device. The first message is used to indicate the value of N, so that the terminal device determines the value of N. Alternatively, the network device may not inform the terminal device of the specific value of N. For example, the network device can send a first message to the terminal device, and the first message does not indicate the value of N, but indicates the maximum value of the timing advance when the terminal device measures the first reference signal. Then the terminal device can determine the value of N based on the maximum value of the timing advance when the terminal device measures the first reference signal. Of course, if the terminal device determines that the value of N is equal to the number of symbols corresponding to the maximum value of the timing advance when the terminal device measures the first reference signal, then it can also be regarded as that the network device indicates the maximum value of the timing advance when the terminal device measures the first reference signal through the first message, and indicates the value of N through the first message. These two operations are equivalent.

[0216] Alternatively, the value of N may also be determined by the terminal device. Further, after determining the value of N, the terminal device may notify or report it to the network device. For example, the terminal device determines the value of N and sends a second message to the network device. The second message is used to indicate the value of N, so that the network device determines the value of N. Alternatively, the terminal device may not inform the network device of the specific value of N. For example, the terminal device may send a second message to the network device, and the second message does not indicate the value of N, but indicates the maximum timing advance (or the maximum value of the timing advance) when the terminal device measures the first reference signal. The network device may then determine the value of N based on the maximum timing advance when the terminal device measures the first reference signal. Of course, if the value of N determined by the terminal device is equal to the number of symbols corresponding to the maximum timing advance when the terminal device measures the first reference signal, then it can also be considered that the terminal device indicates the maximum timing advance when the terminal device measures the first reference signal through the second message, and indicates the value of N through the second message. These two operations are equivalent.

[0217] Whether the value of N is determined by the network device or the terminal device, the following determination method can be used:

[0218] 1. The value of N is a predefined value.

[0219] For example, the value of N is preconfigured by the network device to the terminal device, or the value of N is preconfigured in the terminal device, or the value of N can also be specified by a protocol, such as N=2, or N can also take other values.

[0220] 2. The value of N is determined according to the sub-carrier spacing (SCS) of the serving cell of the terminal device. In other words, the value of N is related to the sub-carrier spacing of the serving cell of the terminal device.

[0221] Different subcarrier spacings result in different lengths of time domain symbols. Therefore, how many second time domain symbols the first time domain range includes can be determined based on the subcarrier spacing of the service cell of the terminal device.

[0222] 3. The value of N is determined according to the frequency range of the service cell of the terminal device, or in other words, the value of N is related to the frequency range of the service cell of the terminal device.

[0223] Frequencies can be divided into different ranges. For example, a coarser-grained division method is to divide frequencies into high frequencies and low frequencies. For example, frequencies greater than or equal to 6 GHz are high frequencies, while frequencies less than 6 GHz are low frequencies. For high frequencies, the radius of the cell is small, so the timing advance used by signals from other devices is relatively small. That is, when measuring the first reference signal, the timing of receiving the first reference signal may not be much advanced relative to the downlink timing of the terminal device in the serving cell. Therefore, the value of N can be relatively small, such as N=1. For low frequencies, the radius of the cell is large, so the timing advance used by signals from other devices is relatively large. That is, when measuring the first reference signal, the timing of receiving the first reference signal may be much advanced relative to the downlink timing of the terminal device in the serving cell. Therefore, the value of N can be relatively large, such as N=2.

[0224] Of course, the frequency division method described here is only an example. In actual applications, the frequency ranges can be divided into more ranges, and the value of N can be different for different frequency ranges. The 6 GHz division point is only an example. Even if the frequency ranges are divided into only two ranges, other division points can be used. Naturally, the value of N is only an example and is not limited to this.

[0225] 4. The value of N is determined according to the timing advance (TA) of the terminal device in the serving cell. In other words, the value of N is related to the timing advance of the terminal device in the serving cell.

[0226] The timing advance can be understood from the perspective of relative time. The timing specified in the communication protocol is relative time. Generally speaking, a time reference point is defined in the communication protocol (this time reference point can be the start time of the wireless frame for downlink reception determined according to the synchronization signal). The uplink transmission timing in the communication protocol usually has a certain offset relative to this time reference point. This offset is the timing advance. The timing advance of the terminal device in the serving cell is the offset of the timing of the terminal device in the serving cell relative to this time reference point.

[0227] The value of N can be determined based on TA. For example, N can be equal to the number of symbols corresponding to TA, or it can be a function of TA. For example, N = k × T, or N = k + T, etc., where T represents the number of symbols corresponding to TA, and k is a coefficient.

[0228] 5. The value of N is determined according to the maximum value of the timing advance when the terminal device measures the first reference signal, or in other words, the value of N is related to the maximum value of the timing advance when the terminal device measures the first reference signal.

[0229] During the measurement process, the terminal device may need to measure the first reference signals from multiple other devices. For different devices, the timing advance determined by the terminal device may be different. For example, for devices that are farther away, the timing advance determined by the terminal device may be larger. Before a measurement process begins, the terminal device can determine the corresponding timing advance for all first reference signals that need to be measured (or for all devices that send first reference signals), and then the value of N can be determined based on the timing advance with the largest value among these timing advances (that is, the maximum value of the timing advance). For example, the value of N can be greater than or equal to the number of symbols corresponding to the timing advance with the largest value, so as to minimize interference with the transmission and reception of signals during the measurement process.

[0230] As described above, several methods for determining the value of N are described. In actual applications, the method selected can be determined by the network device or terminal device, or can also be specified by the protocol. In addition, the embodiments of the present application do not limit the method for determining the value of N. For example, in addition to the several determination methods described above, other possible methods for determining the value of N are also within the scope of protection of the embodiments of the present application.

[0231] As described above, the terminal device does not support the transmission and reception of signals other than the first reference signal during the measurement process. Alternatively, the terminal device may support the transmission and reception of signals other than the first reference signal during the measurement process. In this case, further considerations may arise.

[0232] If the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, the measurement method used by the terminal device when measuring the first reference signal can also be considered. For example, when measuring the first reference signal, the terminal device can use a fixed receive beam method or a beam scanning method. If the beam scanning method is used, the receive beam used by the terminal device during measurement is different from the receive beam used when receiving data from the serving cell. Therefore, if the serving cell sends a signal to the terminal device during the measurement, the terminal device will not be able to receive it.

[0233] Taking this situation into consideration, if the network device determines that the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, and the network device determines that the terminal device does not adopt a beam scanning method during the measurement process, the network device can send a first reference signal to the terminal device within the first time domain range, or receive a first signal from the terminal device within the first time domain range, or send a first signal to the terminal device within the first time domain range, or receive a first signal from the terminal device within the first time domain range and send a third signal to the terminal device, the first signal and the third signal are both signals other than the first reference signal, and the types of the first signal and the third signal can be the same or different. Accordingly, if the terminal device determines that the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, and the terminal device determines that a beam scanning method is not adopted during the measurement process, the terminal device can receive the first reference signal within the first time domain range, or send a first signal to the network device within the first time domain range, or receive a first signal from the network device within the first time domain range, or send a first signal to the network device within the first time domain range and receive a third signal from the network device. That is to say, if the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, and the terminal device does not adopt beam scanning during the measurement process, then the terminal device can send and receive other signals in addition to receiving the first reference signal within the first time domain range. The sending and receiving process of other signals will not be affected by the measurement process, or will be less affected by the measurement process, which can ensure the quality of the sending and receiving process of other signals, and this method can improve communication efficiency.

[0234] Alternatively, if the network device determines that the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, and the network device determines that the terminal device adopts a beam scanning method during the measurement process, the network device does not send signals other than the first reference signal to the terminal device within the first time domain range. This can be understood as the network device may send the first reference signal for measurement to the terminal device within the first time domain range, or may not send the first reference signal to the terminal device, but may not send any signals other than the first reference signal to the terminal device, and the network device may not receive any signals from the terminal device within the first time domain range. Correspondingly, if the terminal device determines that the terminal device supports sending and receiving signals other than the first reference signal during the measurement process, and the terminal device determines that a beam scanning method is adopted during the measurement process, the terminal device only receives the first reference signal within the first time domain range. This can be understood as the terminal device only receives the first reference signal within the first time domain range, does not receive signals other than the first reference signal, and does not send any signals. Alternatively, it can be described as the terminal device not expecting to send or receive signals other than the first reference signal within the first time domain range. Among them, because the terminal device needs to perform measurements within the first time domain range, it can only receive the first reference signal used for measurement, such as SRS, within the first time domain range, and not receive other signals except the first reference signal, nor send any signal, so as to avoid the signal reception and transmission process being interfered with by the measurement process.

[0235] In the embodiments of the present application, the impact of the terminal device on data transmission during measurement is clarified, so that the network device and the terminal device have a consistent understanding of the time domain symbols with scheduling restrictions, and can minimize the failure of receiving and transmitting other signals caused by the terminal device's inability to simultaneously receive and transmit the first reference signal and other signals, as well as the resulting waste of network resources.

[0236] Next, let's consider another issue. In LTE's SRS configuration, a terminal device can transmit SRS through a single antenna port or through multiple antenna ports. When a terminal device transmits SRS through multiple antenna ports, the cyclic shifts corresponding to the SRS transmitted through different antenna ports are different. The difference between the different cyclic shifts is: the maximum number of cyclic shifts / the number of antenna ports.

[0237] If the network device configures multiple terminal devices to send SRS on the same comb structure (comb) of the same symbol, the cyclic shift of the SRS used by different terminal devices is configured separately by the network device. One terminal device does not know the configuration of the SRS sent by other terminal devices, and the network device has no restrictions when configuring the cyclic shift of the SRS of different terminal devices. When the terminal device detects the SRS, it needs to use a detection window. It can be understood that the terminal device will set a corresponding detection window for each SRS that needs to be received, and the terminal device will detect the corresponding SRS within the detection window. The length of the detection window is determined by the minimum difference between the cyclic shifts of the SRS configured by the network device. The smaller the minimum difference between the cyclic shifts of the SRS configured by the network device, the smaller the length of the detection window. The total length of the terminal device detection is fixed, so the smaller the length of the detection window, the greater the number of detection windows. Currently, network devices have no restrictions when configuring the cyclic shift of SRS, so terminal devices can only set the maximum number of detection windows corresponding to comb. For example, if comb = 2, the terminal device needs to set 8 detection windows. If comb = 4, the terminal device needs to set 12 detection windows. It can be seen that the length of the detection window is relatively small. For an SRS, if the timing advance determined by the terminal device is not accurate enough, the SRS is likely to fall outside the detection window corresponding to the SRS. The terminal device will not be able to detect the SRS within the detection window corresponding to the SRS and will consider the detection to have failed. Alternatively, it is possible that the difference between the cyclic shifts of the two SRSs is relatively small, and the timing of the two SRSs arriving at the terminal device performing the measurement is different, which may cause the two SRSs received by the terminal device to overlap. In this case, the terminal device will only consider that one SRS has been received and that the detection of the other SRS has failed.

[0238] In view of this, the embodiment of the present application provides a second communication method, which can solve the problem of detection errors caused by unreasonable detection window settings. Figure 4 , which is the flow chart of this method. In the following introduction, this method is applied to Figure 2Take the network architecture shown as an example. In addition, the method can be performed by two communication devices, such as a first communication device and a second communication device, wherein the first communication device can be a network device or a communication device that can support the network device to implement the functions required by the method, or the first communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required by the method, of course, it can also be other communication devices, such as a chip system. The same is true for the second communication device. The second communication device can be a network device or a communication device that can support the network device to implement the functions required by the method, or the second communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required by the method, of course, it can also be other communication devices, such as a chip system. There is no restriction on the implementation methods of the first communication device and the second communication device, for example, the first communication device can be a network device, the second communication device is a terminal device, or the first communication device and the second communication device are both network devices, or the first communication device and the second communication device are both terminal devices, or the first communication device is a network device, and the second communication device is a communication device that can support the terminal device to implement the functions required by the method, and so on. Wherein, the network device is, for example, a base station.

[0239] For the sake of convenience, the following takes the method executed by the network device and the terminal device as an example, that is, the first communication device is the network device and the second communication device is the terminal device as an example. Figure 2 The network architecture shown, therefore, the network devices described below can be Figure 2 The network devices in the network architecture shown in the figure, the terminal devices described below can be Figure 2 The other devices described below may be terminal devices, such as Figure 2 The terminal device in the neighboring area of ​​the service cell of the terminal device shown in , or it can also be a network device, such as Figure 2 Other network devices not shown in the figure. The neighboring area of ​​the serving cell can be Figure 2 The network equipment shown is provided, or it can be Figure 2 Provided by another network device not shown.

[0240] S41. The network device determines measurement configuration information, where the measurement configuration information is used to instruct the terminal device to measure multiple first reference signals, and the minimum value of the difference between each of the multiple cyclic shifts corresponding to the multiple first reference signals configured by the network device is greater than or equal to M, and the multiple first reference signals are reference signals located on the same time domain symbol and corresponding to the same comb structure.

[0241] The network device may configure the terminal device to perform a measurement, such as a CLI measurement, or other measurements.

[0242] The first reference signal may be a reference signal used by the terminal device to perform measurements. The first reference signal may be, for example, SRS, or may be other reference signals, such as CSI-RS, etc., without specific limitation. There may be multiple reference signals, but only the reference signal used by the terminal device in the embodiment of the present application to perform measurements is called the first reference signal. Correspondingly, it can be understood that the measurement process described in the embodiment of the present application is a measurement process corresponding to the first reference signal, or in other words, in the measurement process, the terminal device needs to measure the first reference signal. For example, the network device configures the terminal device to measure reference signal 1, and the terminal device may receive reference signal 1 and reference signal 2, but the network device does not configure the terminal device to measure reference signal 2, then reference signal 1 is the first reference signal, and reference signal 2 is not the first reference signal.

[0243] The first reference signal may be sent by a first device. Of course, if there are multiple first reference signals, the multiple first reference signals may come from at least one first device. The first device may be a terminal device or a network device, and there is no limitation on the type of the first device.

[0244] The first reference signal can be sent in the form of a sequence. The network device can then configure a cyclic shift for each first reference signal. Different first reference signals correspond to different cyclic shifts, allowing the terminal device to distinguish between different first reference signals. Since different first reference signals correspond to different cyclic shifts, there will be a corresponding difference between the two cyclic shifts. Multiple first reference signals can correspond to multiple cyclic shifts, and there will be a difference between each two first reference signals. The first reference signal and the cyclic shift can have a one-to-one correspondence. In an embodiment of the present application, the network device can configure the minimum difference between the multiple cyclic shifts corresponding to the multiple first reference signals to be greater than or equal to M. In other words, among the multiple cyclic shifts configured by the network device, the difference between any two cyclic shifts must be greater than or equal to M. It will be understood that the difference between the cyclic shifts mentioned here can refer to the actual difference between the cyclic shifts or the absolute value of the actual difference between the cyclic shifts.

[0245] For example, a network device is configured with M = 1. Furthermore, the network device is configured with four first reference signals: first reference signal 1, first reference signal 2, first reference signal 3, and first reference signal 4. First reference signal 1 corresponds to cyclic shift 1, first reference signal 2 corresponds to cyclic shift 2, first reference signal 3 corresponds to cyclic shift 3, and first reference signal 4 corresponds to cyclic shift 4. The network device can configure cyclic shift 1 to 2, cyclic shift 2 to 3, cyclic shift 3 to 5, and cyclic shift 4 to 7. The difference between cyclic shift 1 and cyclic shift 2 is 1, the difference between cyclic shift 1 and cyclic shift 3 is 3, the difference between cyclic shift 1 and cyclic shift 4 is 6, the difference between cyclic shift 2 and cyclic shift 3 is 2, and the difference between cyclic shift 3 and cyclic shift 4 is 2. Since M = 1, it can be seen that the cyclic shifts of the four first reference signals configured by the network device meet the requirements.

[0246] The value of M can be determined in one of the following ways:

[0247] 1. The value of M is a predefined value.

[0248] For example, the value of M is preconfigured by the network device for the terminal device, or the value of M is preconfigured in the terminal device, or the value of M can also be specified by the protocol. For example, the value of M is the maximum number of configurable cyclic shifts divided by 2, or M can also take other values. Of course, if M = the maximum number of configurable cyclic shifts / 2, then the maximum number of first reference signals configured by the network device for the same symbol and the same comb structure is 2. The terminal device then only needs to set two detection windows during detection.

[0249] The maximum number of configurable cyclic shifts is related to comb. For example, if comb=2, the maximum number of configurable cyclic shifts is 8; if comb=4, the maximum number of configurable cyclic shifts is 12.

[0250] 2. The value of M is determined based on the maximum timing error that the terminal device can handle. In other words, the value of M is related to the maximum timing error that the terminal device can handle.

[0251] For example, the timing determined by the terminal device for the first reference signal (or the timing determined for the signal from other devices) may be relatively accurate, or may not be accurate enough, that is, there may be a timing error. Generally speaking, if the timing error determined by the terminal device is less than or equal to the maximum timing error that the terminal device can handle, then although there is an error between the arrival time of the first reference signal and the timing determined by the terminal device, the terminal device can still receive and measure the first reference signal normally and meet the corresponding measurement index requirements. However, if the timing error determined by the terminal device is greater than the maximum timing error that the terminal device can handle, the terminal device may not be able to receive or process the first reference signal normally. Therefore, the value of M can be determined based on the maximum timing error that the terminal device can handle.

[0252] The maximum timing error that the terminal device can handle is, for example, the length of a cyclic prefix (CP), or it may be other lengths. For example, the maximum timing error that the terminal device can handle is the length of the CP, and the time resolution corresponding to a single cyclic shift is f, then M can be equal to G / f, and G represents the length of a CP. Among them, for a comb, when the number corresponding to the detection window is the largest, the length of a detection window represents the time resolution of the cyclic shift corresponding to the detection window. For example, if comb=2, the number of cyclic shifts is 8, and the maximum number corresponding to the detection window is 8, then the terminal device will set 8 detection windows, each detection window corresponds to a cyclic shift, and the length of a detection window is the time resolution of the cyclic shift corresponding to the detection window.

[0253] 3. The value of M is determined according to the frequency range to which the frequency of the service cell of the terminal device belongs. In other words, the value of M is related to the frequency range to which the frequency of the service cell of the terminal device belongs.

[0254] Frequencies can be divided into different ranges. For example, a coarser-grained division method is to divide frequencies into high frequencies and low frequencies. For example, frequencies greater than or equal to 6 GHz are high frequencies, while frequencies less than 6 GHz are low frequencies. For high frequencies, the radius of the cell is smaller. When the terminal device receives the first reference signal from other devices, the error between the actual reception time and the timing determined by the terminal device for the first reference signal may also be relatively small. Then, even if the terminal device sets the length of the detection window to be smaller, the possibility of the first reference signal falling into the detection window corresponding to other cyclic shifts is also smaller, and the terminal device may be able to normally receive the first reference signal from other devices. Therefore, in this case, M can be set to be smaller so that the terminal device can receive as many first reference signals as possible and improve the accuracy of the measurement. For example, M = 2.

[0255] For low frequencies, the cell radius is larger. Therefore, when a terminal device receives a first reference signal from another device, the error between the actual reception time and the timing determined by the terminal device for that first reference signal may be relatively large. Therefore, if the terminal device sets the detection window length to a smaller value, reception errors may occur. For example, the first reference signal may fall outside the detection window, or multiple first reference signals may overlap. Therefore, in this case, M can be set larger to improve the terminal device's measurement accuracy. For example, M = 4.

[0256] Of course, the frequency division method described here is only an example. In actual applications, the frequency ranges can be divided into more ranges, and the value of N can be different for different frequency ranges. The 6 GHz division point is only an example; even if the frequency ranges are divided into only two ranges, other division points can be used. Naturally, the value of M is only an example and is not limited to this.

[0257] 4. The value of M is determined according to the subcarrier spacing of the serving cell of the terminal device, or in other words, the value of M is related to the subcarrier spacing of the serving cell of the terminal device.

[0258] Different subcarrier spacings result in different lengths of time domain symbols, so the value of M can also be determined based on the subcarrier spacing of the serving cell of the terminal device.

[0259] As described above, several methods for determining the value of M are described. Which method is selected in actual applications can be configured by the network device or specified by the protocol. In addition, the embodiments of the present application do not limit the method for determining the value of M. For example, in addition to the several determination methods described above, other possible methods for determining the value of M are also within the scope of protection of the embodiments of the present application.

[0260] S42. The network device sends measurement configuration information to the terminal device, and the terminal device receives the measurement configuration information from the network device, where the measurement configuration information is used to instruct the terminal device to measure multiple first reference signals.

[0261] After determining the measurement configuration information, the network device may send the measurement configuration information to the terminal device.

[0262] The value of M can be determined by the network device, and after the network device determines the value of M, it can send the value of M to the terminal device. For example, the network device sends a first message to the terminal device, and the terminal device receives the first message from the network device, and the first message is used to indicate the value of M. For example, in addition to indicating the value of M, the first message can also carry the measurement configuration information in S42, which is equivalent to the network device sending both the measurement configuration information and the value of M to the terminal device through the first message, or the first message only indicates the value of M, and the measurement configuration information in S42 is carried in other messages, that is, the network device can also send the measurement configuration information and the value of M to the terminal device through different messages. If the network device sends the measurement configuration information and the value of M to the terminal device through different messages, then the network device can send the measurement configuration information first and then send the value of M, or send the value of M first and then send the measurement configuration information, or send the measurement configuration information and the value of M at the same time.

[0263] Alternatively, the network device can determine the value of M, and the terminal device can also determine the value of M, without the network device sending the value of M to the terminal device. Both the network device and the terminal device can use one of the several determination methods described in S41 when determining the value of M. The determination methods used by the network device and the terminal device should be the same, so that the values ​​of M determined by the network device and the terminal device are the same.

[0264] S43. When the terminal device determines that the minimum value of the difference between each of the multiple cyclic shifts corresponding to the multiple first reference signals is greater than or equal to M, the terminal device measures the multiple first reference signals according to the measurement configuration information.

[0265] The terminal device expects that the minimum value of the difference between the multiple cyclic shifts corresponding to the multiple first reference signals configured by the network device is greater than or equal to M, but the terminal device is not initially sure whether the network device has adopted this configuration. Therefore, the terminal device can first determine whether the minimum value of the difference between the multiple cyclic shifts corresponding to the multiple first reference signals is greater than or equal to M. If the minimum value of the difference between the multiple cyclic shifts corresponding to the multiple first reference signals is less than M, the terminal device may not measure (or be described as, the terminal device does not expect (not expected) measurement, or, the terminal device does not need (not required) measurement) these multiple first reference signals. That is to say, among the differences between the multiple cyclic shifts corresponding to the multiple first reference signals, as long as one difference is less than M, the terminal device may not measure these multiple first reference signals.

[0266] If the terminal device determines that the minimum value of the difference between two of the multiple cyclic shifts corresponding to the multiple first reference signals is greater than or equal to M, the terminal device may measure the multiple first reference signals according to the measurement configuration information.

[0267] If the minimum difference of the cyclic shift is not restricted, the terminal device can only detect according to the worst case, that is, the detection window corresponding to each cyclic shift is the time resolution of a single cyclic shift (the minimum is 1 / 48 of the time domain symbol). This may cause the terminal device to miss or misdetect the first reference signal, thereby reducing the accuracy of the measurement. However, the method provided in the embodiment of the present application defines the minimum distance between the cyclic shifts of multiple first reference signals on the same comb of the same time domain symbol. The terminal device can adjust the size of the detection window corresponding to each cyclic shift accordingly during detection, so that the measured first reference signal can fall into the corresponding detection window as much as possible, thereby improving the accuracy of the measurement.

[0268] Or, to resolve Figure 4 The embodiment shown in FIG2 is intended to solve the same problem. The embodiment of the present application provides a third communication method, which can solve the problem of detection errors caused by unreasonable detection window settings. Figure 5 , which is the flow chart of this method. In the following introduction, this method is applied to Figure 2 Take the network architecture shown as an example. In addition, the method can be performed by two communication devices, such as a first communication device and a second communication device, wherein the first communication device can be a network device or a communication device that can support the network device to implement the functions required by the method, or the first communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required by the method, of course, it can also be other communication devices, such as a chip system. The same is true for the second communication device. The second communication device can be a network device or a communication device that can support the network device to implement the functions required by the method, or the second communication device can be a terminal device or a communication device that can support the terminal device to implement the functions required by the method, of course, it can also be other communication devices, such as a chip system. There is no restriction on the implementation methods of the first communication device and the second communication device, for example, the first communication device can be a network device, the second communication device is a terminal device, or the first communication device and the second communication device are both network devices, or the first communication device and the second communication device are both terminal devices, or the first communication device is a network device, and the second communication device is a communication device that can support the terminal device to implement the functions required by the method, and so on. Wherein, the network device is, for example, a base station.

[0269] For the sake of convenience, the following takes the method executed by the network device and the terminal device as an example, that is, the first communication device is the network device and the second communication device is the terminal device as an example. Figure 2 The network architecture shown, therefore, the network devices described below can be Figure 2 The network devices in the network architecture shown in the figure, the terminal devices described below can be Figure 2 The other devices described below may be terminal devices, such as Figure 2 The terminal device in the neighboring area of ​​the service cell of the terminal device shown in , or it can also be a network device, such as Figure 2 Other network devices not shown in the figure. The neighboring area of ​​the serving cell can be Figure 2 The network equipment shown is provided, or it can be Figure 2 Provided by another network device not shown.

[0270] S51. The network device determines measurement configuration information, where the measurement configuration information is used to instruct the terminal device to measure multiple first reference signals, and among the multiple first reference signals indicated by the measurement configuration information, there are not at least two first reference signals located on the same time domain symbol and corresponding to the same comb structure.

[0271] The first reference signal may be a reference signal used by the terminal device to perform measurements. The first reference signal may be, for example, SRS, or may be other reference signals, such as CSI-RS, etc., without specific limitation. There may be multiple reference signals, but only the reference signal used by the terminal device in the embodiment of the present application to perform measurements is called the first reference signal. Correspondingly, it can be understood that the measurement process described in the embodiment of the present application corresponds to the first reference signal, or in other words, in the measurement process, the terminal device needs to measure the first reference signal. For example, the network device configures the terminal device to measure reference signal 1, and the terminal device may receive reference signal 1 and reference signal 2, but the network device does not configure the terminal device to measure reference signal 2, then reference signal 1 is the first reference signal, and reference signal 2 is not the first reference signal.

[0272] The first reference signal may be sent by a first device. Of course, if there are multiple first reference signals, the multiple first reference signals may come from at least one first device. The first device may be a terminal device or a network device, and there is no limitation on the type of the first device.

[0273] Among them, among the multiple first reference signals indicated by the measurement configuration information, there are not at least two first reference signals located on the same time domain symbol and corresponding to the same comb. It can also be described as that, among the multiple first reference signals indicated by the measurement configuration information, there are no other first reference signals in the time domain symbol where each first reference signal is located and the corresponding comb.

[0274] The network device may configure the terminal device to perform a measurement, such as a CLI measurement, or other measurement. The first reference signal may be, for example, an SRS, or other reference signals such as a CSI-RS, without specific limitation. The first reference signal may be sent by the first device. Of course, if there are multiple first reference signals, the multiple first reference signals may come from at least one first device. The first device may be a terminal device, or a network device, etc., without limitation to the type of the first device.

[0275] As mentioned above, if a network device configures multiple terminal devices to send SRS on the same comb of the same symbol, the cyclic shift of the SRS used by different terminal devices is configured separately by the network device, and one terminal device does not know the configuration of the SRS sent by other terminal devices, and the network device has no restrictions when configuring the cyclic shift of the SRS of different terminal devices. This results in the terminal device being able to set the detection window only according to the maximum number, and the length of the detection window is small, resulting in a high possibility of false detection or missed detection of the reference signal bandwidth by the terminal device. Therefore, in an embodiment of the present application, the network device can configure multiple first reference signals, and there are no two first reference signals located on the same time domain symbol and corresponding to the same comb, that is, among the multiple first reference signals configured by the network device, the time domain symbols corresponding to any two reference signals are different, or the combs corresponding to any two reference signals are different, or the time domain symbols and the corresponding combs corresponding to any two reference signals are different. In this way, possible problems are avoided and the accuracy of terminal device detection is improved.

[0276] For example, a network device is configured with four first reference signals: first reference signal 1, first reference signal 2, first reference signal 3, and first reference signal 4. First reference signal 1 corresponds to time domain symbol 1, first reference signal 2 corresponds to time domain symbol 2, first reference signal 3 corresponds to time domain symbol 2, and first reference signal 4 corresponds to time domain symbol 3. First reference signal 1 corresponds to comb1, first reference signal 2 corresponds to comb2, first reference signal 3 corresponds to comb1, and first reference signal 4 corresponds to comb2. It can be seen that although first reference signal 1 and first reference signal 3 correspond to the same comb, they correspond to different time domain symbols. While first reference signal 2 and first reference signal 3 correspond to the same time domain symbol, they correspond to different combs. In other words, no two first reference signals are located on the same time domain symbol and correspond to the same comb.

[0277] As an optional implementation, the measurement configuration information may instruct the terminal device to measure multiple first reference signals as well as multiple second reference signals, where the multiple second reference signals are located on the same time domain symbol and correspond to the same comb.

[0278] The second reference signal may also be a reference signal used by the terminal device to perform measurements. The second reference signal may be, for example, an SRS, or may be another reference signal, such as a CSI-RS, without limitation. There may be multiple reference signals, but only the reference signal used by the terminal device to perform measurements in the embodiments of the present application is referred to as the first reference signal or the second reference signal. In other words, during the measurement process, the terminal device needs to measure the first reference signal, or the first reference signal and the second reference signal.

[0279] The second reference signal can be transmitted by a second device. Of course, if there are multiple second reference signals, the multiple second reference signals can come from at least one second device. The second device can be a terminal device, or it can also be a network device, etc. There is no restriction on the type of the second device. Furthermore, the type of the first device and the type of the second device can be the same, for example, both are terminal devices, or the type of the first device and the type of the second device can be different, for example, the first device is a terminal device and the second device is a network device. In addition, the same device may be able to transmit both the first reference signal and the second reference signal, so the device can function as both the first device and the second device.

[0280] For example, the network device is also configured with two second reference signals, namely second reference signal 1 and first reference signal 2. Second reference signal 1 corresponds to time domain symbol 1, second reference signal 2 corresponds to time domain symbol 1, second reference signal 1 corresponds to comb1, and second reference signal 2 also corresponds to comb1. Therefore, second reference signal 1 and second reference signal 2 correspond to the same time domain symbol and the same comb.

[0281] S52. The network device sends measurement configuration information to the terminal device, and the terminal device receives the measurement configuration information from the network device, where the measurement configuration information is used to instruct the terminal device to measure multiple reference signals.

[0282] After determining the measurement configuration information, the network device may send the measurement configuration information to the terminal device.

[0283] S53. When the terminal device determines that there are not at least two first reference signals among the multiple first reference signals that are located on the same time domain symbol and correspond to the same comb structure, the terminal device measures the multiple first reference signals according to the measurement configuration information.

[0284] In which, the terminal device determines that among multiple first reference signals, there are not at least two first reference signals located on the same time domain symbol and corresponding to the same comb. It can also be described as that the terminal device determines that among multiple first reference signals, each first reference signal is located in the time domain symbol and the corresponding comb and there are no other first reference signals.

[0285] The terminal device expects that at least two of the multiple first reference signals configured by the network device do not reside on the same time domain symbol and correspond to the same comb. However, the terminal device is initially unsure whether the network device has adopted this configuration. Therefore, the terminal device may first determine whether at least two of the multiple first reference signals do not reside on the same time domain symbol and correspond to the same comb. If the terminal device determines that at least two of the multiple first reference signals do not reside on the same time domain symbol and correspond to the same comb, the terminal device may measure the multiple reference signals according to the measurement configuration information.

[0286] If the network device also configures multiple second reference signals through measurement configuration information, the terminal device can determine whether at least two of the multiple second reference signals are located on the same time domain symbol and correspond to the same comb. However, since the multiple second reference signals configured by the network device are located on the same time domain symbol and correspond to the same comb, the terminal device's determination result is that the multiple second reference signals are located on the same time domain symbol and correspond to the same comb. In this case, the terminal device may not measure the multiple second reference signals to reduce measurement errors.

[0287] Through the method provided in the embodiment of the present application, no two first reference signals among the multiple first reference signals configured by the network device are located in the same time domain symbol and correspond to the same comb. This is equivalent to fundamentally solving the cause of the problem of false detection or missed detection of reference signals by the terminal device, and helps to improve the measurement accuracy of the terminal device.
