Description

[0001] This application is a divisional application filed again for a divisional application. The application number of the divisional application targeted is 202210298409.0, the application number of the original application is 201910365273.9, the filing date of the original application is April 30, 2019, and the entire content of the original application is incorporated herein by reference. Technical Field

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

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

[0004] Currently, Technical Specification (TS) 38.133 defines the scheduling restrictions for radio resource management (RRM) measurements caused by the mixed subcarrier spacing and receive beam scanning. Among them, the mixed subcarrier spacing means that the subcarrier spacing of the synchronization signal and the physical broadcast channel block (SSB) is different from that of the data. When the terminal device does not support receiving two different subcarrier spacings simultaneously, scheduling restrictions will occur; the reason why receive beam scanning causes scheduling restrictions is that the receive beam used by the terminal device during measurement is different from the receive beam used when receiving data in the serving cell. Therefore, the terminal device cannot transmit and receive data with the serving cell during measurement. The so-called scheduling restriction means that the terminal device may not receive data on the specified symbol.

[0005] The current RRM measurements are based on the downlink timing of the terminal device, but the CLI measurements are based on the timing determined by the terminal device itself. Generally, there is an advance compared to the downlink timing of the terminal device. Therefore, the scheduling restrictions of the existing RRM measurements are not applicable to CLI measurements, and it is currently unclear on which symbols the terminal device will have scheduling restrictions during CLI measurements. Summary of the Invention

[0006] Embodiments of this application provide a communication method and device for clarifying the scheduling restrictions generated when a terminal device performs CLI measurements.

[0007] In a first aspect, a first communication method is provided. The method includes: The terminal device determines whether the terminal device supports receiving and transmitting signals other than a first reference signal during the measurement process, where the first reference signal is used by the terminal device to perform measurements during the measurement process; when the terminal device does not support receiving and transmitting 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, where 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 and / or N time domain symbols after the first time domain symbol, and N is a positive integer.

[0008] This method can be executed by a first communication device. The first communication device can be a communication device or a communication device that can support the functions required for the communication device to implement this method, such as a chip system. Exemplarily, the communication device is a terminal device.

[0009] In an embodiment of the present application, the terminal device may 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 it does not support receiving and transmitting signals other than the first reference signal during the measurement process, then 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 transmitting any signals. Similarly, the network device may also only send the first reference signal to the terminal device within the first time domain range. Of course, the network device may also not send the first reference signal to the terminal device, but does not send signals other than the first reference signal to the terminal device and does not receive any signals from the terminal device. That is to say, if the measurement of the first reference signal by the terminal device affects the signal reception and transmission, both the terminal device and the network device can determine the scheduling restrictions when the terminal device is performing the measurement. Thus, the terminal device may not receive signals other than the first reference signal and does not transmit any signals on the time domain symbols with scheduling restrictions, so as to avoid interference to the reception and transmission of other signals caused by the measurement as much as possible.

[0010] In combination with the first aspect, in a possible implementation manner 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 serving cell of the terminal device; or, the value of N is determined according to the frequency range to which the frequency of the serving cell of the terminal device belongs; or, the value of N is determined according to the timing advance of the terminal device in the serving cell; or, the value of N is determined according to the maximum value of the timing advance when the terminal device measures the first reference signal.

[0011] Regarding the value of N, there are multiple possible determination methods. Which method to specifically select can be configured by the network device or specified by the protocol, etc., which is relatively flexible.

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

[0013] The value of N can be determined by the network device, and after the network device determines it, it can inform the terminal device. Thus, the terminal device does not need to determine the value of N anymore, 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 manner of the first aspect, the method further includes: the terminal device sends a second message to the network device, and 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 after the terminal device determines it, it can inform the network device. As a result, the network device does not need to determine the value of N anymore, which can make the terminal device and the network device consistent in the value of N and reduce the workload of the network device.

[0016] Combined with the first aspect, in a possible implementation manner of the first aspect, the method further includes: the terminal device sends a second message to the network device, and 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 have to send the 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, and the network device can determine the value of N by itself according to the maximum value of the timing advance when the terminal device measures the first reference signal.

[0018] Combined with the first aspect, in a possible implementation manner of the first aspect, the method further includes: when the terminal device determines that the terminal device supports receiving and sending other signals except the first reference signal during the measurement process, and the terminal device determines not to adopt the beam scanning method 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 other signals except the first reference signal.

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

[0020] In combination with the first aspect, in a possible implementation manner of the first aspect, the method further includes: when the terminal device determines that the terminal device supports receiving and transmitting signals other than the first reference signal during the measurement process, and the terminal device determines to adopt 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 not to adopt a beam scanning method when measuring the first reference signal, then the receiving beam used by the terminal device during measurement may be different from the receiving beam used when receiving the downlink data of the serving cell. Therefore, during the measurement process, the terminal device cannot receive the downlink signal from the serving cell. Thus, even if the terminal device determines that it supports receiving and transmitting signals other than the first reference signal during the measurement process, the terminal device can also only receive the first reference signal within the first time domain range. It can be understood that 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 transmit any signals. Similarly, the network device can also only send the first reference signal to the terminal device within the first time domain range. Of course, the network device may also not send the first reference signal to the terminal device, but does not send signals other than the first reference signal to the terminal device and does not receive any signals from the terminal device. In this way, interference to the reception and transmission of other signals caused by measurement is minimized.

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

[0023] The terminal device can send the capability information of the terminal device to the network device, so that the network device can determine whether the terminal device supports receiving and transmitting signals other than the first reference signal during the measurement process according to the capability information of the terminal device. Of course, the network device can also determine whether the terminal device supports receiving and transmitting signals other than the first reference signal during the measurement process according to other factors, and no specific limitation is made.

[0024] Second aspect, a second communication method is provided. The method includes: A network device determines whether a terminal device supports receiving and transmitting signals other than a first reference signal during a measurement process, where the first reference signal is used for the terminal device to perform measurements during the measurement process; When it is determined that the terminal device does not support receiving and transmitting 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, where 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] This method can be executed by a second communication device, which can be a communication device or a communication device capable of supporting the functions required for the communication device to implement this method, such as a chip system. Exemplarily, the communication device is a network device.

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

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

[0028] In combination with the second aspect, in a possible implementation manner 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 value of N.

[0029] In combination with the second aspect, in a possible implementation manner 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 when the terminal device measures the first reference signal.

[0030] In combination with the second aspect, in a possible implementation manner of the second aspect, the method further includes: when the network device determines that the terminal device supports receiving and transmitting 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 manner during the measurement process, the network device transmits the first reference signal to the terminal device within the first time domain range, and receives and / or transmits 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 manner of the second aspect, the method further includes: when the network device determines that the terminal device supports receiving and transmitting signals other than the first reference signal during the measurement process, and the network device determines that the terminal device adopts a beam scanning manner during the measurement process, the network device only transmits the first reference signal within the first time domain range.

[0032] In combination with the second aspect, in a possible implementation manner of the second aspect, for the network device to determine whether the terminal device supports receiving and transmitting signals other than the first reference signal during the measurement process, it includes: the network device receives the capability information of the terminal device from the terminal device, and the network device determines whether the terminal device supports receiving and transmitting signals other than the first reference signal during the measurement process according to the capability information.

[0035] This method can be executed by a third communication device. The third communication device may be a communication device or a communication device capable of supporting the functions required for the communication device to implement this method, such as a chip system. Exemplarily, the communication device is a terminal device.

[0036] If there is no restriction on the minimum difference of cyclic shifts, the terminal device can only detect in the worst - case scenario, that is, the detection window corresponding to each cyclic shift is the time resolution of a single cyclic shift (at least 1 / 48 time - domain symbols). This may lead to the terminal device missing or misdetecting the first reference signal, reducing the measurement accuracy. However, through the method provided in the embodiments of the present application, the minimum distance between the cyclic shifts of multiple first reference signals on the same time - domain symbol and the same comb is defined. The terminal device can correspondingly adjust the size of the detection window corresponding to each cyclic shift during detection, so that the measured first reference signal can fall into the corresponding detection window as much as possible, improving the measurement accuracy.

[0037] In combination with the third aspect, in a possible implementation manner 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 serving cell of the terminal device belongs; or, the value of M is determined according to the sub - carrier spacing of the serving cell of the terminal device.

[0038] The value of M can also be determined by the terminal device. After the terminal device determines it, it can inform the network device. Thus, the network device does not need to determine the value of M anymore, 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 manner of the third aspect, the method further includes: the terminal device receives a first message from the network device, and the first message is used to indicate the value of M.

[0040] The terminal device can determine the value of M by itself according to one of the above - mentioned several methods. Or the value of M can also be determined by the network device. After the network device determines it, it can send the value of M to the terminal device, so that the terminal device does not need to determine the value of M.

[0042] This method can be executed by a fourth communication device.

[0047] This method can be executed by a fifth communication device. The fifth communication device may be a communication device or a communication device capable of supporting the functions required for the communication device to implement this method, such as a chip system. Exemplarily, the communication device is a terminal device.

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

[0170] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0171] The following explains some terms in the embodiments of the present application to facilitate understanding by those skilled in the art.

[0172] 1) A terminal device includes a device that provides voice and / or data connectivity to a user. For example, it may include a handheld device with wireless connection capabilities, or a processing device connected to a wireless modem. The terminal device can communicate with the core network via a radio access network (RAN) and exchange voice and / or data with the RAN. The terminal device may include a user equipment (UE), a wireless terminal device, a mobile terminal device, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point (AP), a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, etc. For example, it may include a mobile phone (or a "cellular" phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, computer-integrated or vehicle-mounted mobile device, a smart wearable device, etc. For example, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. It also includes restricted devices, such as devices with lower power consumption, or devices with limited storage capacity, or devices with limited computing capacity, etc. For example, it includes information sensing devices such as barcodes, radio frequency identification (RFID), sensors, global positioning system (GPS), laser scanners, etc.

[0173] By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. A wearable device, also known as a wearable intelligent device, is a general term for devices developed by applying wearable technology to the intelligent design of daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is directly worn on the body or integrated into the user's clothes or accessories. A wearable device is not just a hardware device, but also realizes powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable intelligent devices include those with complete functions and large sizes that can achieve complete or partial functions without relying on a smartphone, such as smart watches or smart glasses, etc., and those that only focus on a certain type of application function and need to cooperate with other devices such as smartphones, such as various smart bracelets for vital sign monitoring, smart helmets, and smart jewelry.

[0174] 2) Network devices, for example, including access network (AN) devices, such as base stations (for example, access points), which may refer to devices in the access network that communicate with wireless terminal devices through one or more cells over the air interface. Or, for example, in a V2X technology, the network device is a roadside unit (RSU). The base station can be used to mutually convert the received air frames and Internet Protocol (IP) packets, and act as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network. The RSU can be a fixed infrastructure entity that supports vehicle-to-everything (V2X) applications and can exchange messages with other entities that support V2X applications. The access network device can also coordinate the attribute management of the air interface. For example, the access network device may include an evolved Node B (NodeB or eNB or e-NodeB, evolutional Node B) in a Long Term Evolution (LTE) system or a Long Term Evolution - Advanced (LTE-A) system, or may also include a next-generation Node B (gNB) in a 5th generation (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. The embodiments of the present application do not limit this.

[0175] Of course, the network device may further include a core network device. However, since the technical solution provided by the embodiments of this application mainly relates to an access network device, hereinafter, unless otherwise specified, the "network device" described hereinafter refers to an access network device.

[0176] 3) RRM measurement refers to the measurement performed by a terminal device to support radio resource management and mobility management. The measurement target, measurement quantity, and corresponding reporting criteria, etc., are generally configured by the network. Common RRM measurements include synchronization signal (SS)-RSRP measurement, or SS-reference signal received quality (RSRQ), etc. The terminal device can perform measurements according to the configuration of the network device and report the measurement results to the network device.

[0177] 4) In the embodiments of this application, the terms "system" and "network" can be used interchangeably. "At least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c can be single or multiple.

[0178] Moreover, unless otherwise stated, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, time sequence, priority, or importance of multiple objects. For example, the first identifier and the second identifier are only used to distinguish different identifiers, rather than indicating differences in the content, priority, or importance of these two identifiers, etc.

[0179] Some concepts related to the embodiments of this application are introduced above. Next, the technical features of the embodiments of this application are introduced.

[0180] In the NR WI RIM / CLI of Rel-16, CLI measurements on the terminal device side are introduced, mainly for evaluating the interference level of the uplink transmission of neighboring cell terminal devices on the terminal device in the serving cell receiving downlink data from the serving cell when using dynamic uplink-downlink ratios. CLI measurements can include two types of measurements: SRS-RSRP and CLI-RSSI. Among them, SRS-RSRP measures the RSRP of the SRS from the terminal device in the neighboring cell, and CLI-RSSI measures the RSSI 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 scenario for CLI measurement. Figure 1 It includes network device 1, network device 2, terminal device 1, and terminal device 2. Among them, 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 SRS, or 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 neighboring 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, thus interfering with the receiving 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, other devices from cell 2, or, other devices from terminal device 2 and cell 2, or, devices from terminal device 2 and other cells, or, devices from other cells, or, other devices from cell 2 and other cells, or, devices from terminal device 2, other devices from cell 2, and other cells) to determine the interference level and make corresponding scheduling decisions or cooperate with network device 2, etc.

[0182] Of course, Figure 1 This is an example where the two cells are provided by different network devices. It is also possible that cell 1 where terminal device 1 is located and cell 2 where terminal device 2 is located are provided by the same network device, but cell 1 and cell 2 are adjacent. Then, the SRS sent by terminal device 2 may also be received by terminal device 1, thus interfering with the transceiver process of terminal device 1. In this case, terminal device 1 can also measure the RSRP or RSSI of the SRS from terminal device 2 to determine the interference level.

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

[0184] Regarding the timing of CLI measurement, according to the conclusion of RAN1, it is determined by the implementation of the terminal device. The timing of CLI measurement refers to when the terminal device should detect the reference signal for CLI measurement when performing CLI measurement. The reference signal for CLI measurement is sent by the terminal device in the neighboring cell. Therefore, relative to the downlink timing of the terminal device in the serving cell, the timing of CLI measurement generally has a time advance relative to the downlink timing of the serving cell.

[0185] The current RRM measurement is based on the downlink timing of the terminal device in the serving cell. Among them, 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, the measurement of CLI is based on the timing determined by the terminal device itself, and the timing determined by the terminal device itself generally has an advance relative to the downlink timing of the terminal device. Therefore, the scheduling restrictions of the existing RRM measurement are not applicable to the CLI measurement, and it is currently unclear on which symbols the terminal device will have scheduling restrictions when performing CLI measurement.

[0186] Currently, TS 38.133 defines the scheduling restrictions caused by the hybrid subcarrier spacing and the receive beam scanning for RRM measurement. Among them, the hybrid subcarrier spacing means that the subcarrier spacing of the SSB is different from the subcarrier spacing of the data, and scheduling restrictions will occur when the terminal device does not support receiving two different subcarrier spacings simultaneously; the reason why the receive beam scanning causes scheduling restrictions is that the receive beam used by the terminal device during measurement is different from the receive beam used when receiving data in the serving cell. Therefore, the terminal device cannot perform data transmission with the serving cell during measurement. The so-called scheduling restriction means that the terminal device can not receive data on the specified symbols.

[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 may determine whether the terminal device supports receiving and sending 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 sending 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. Receiving only the first reference signal within the first time domain can be understood as the terminal device only receiving the first reference signal within the first time domain, not receiving other signals other than 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 other signals other than the first reference signal may not be received on the time domain symbols with scheduling restrictions, and no signals may be sent. Clarifying the scheduling restrictions can minimize the failure of receiving and sending other signals caused by the inability of the terminal device to simultaneously receive and send the first reference signal and other signals, as well as 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 may 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 from 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 context] is, for example, an access network device, such as a base station. Among them, the network device corresponds to different devices in different systems. For example, in the 4th generation (4G) mobile communication technology system, it can correspond to an eNB, and in the 5G system, it can correspond to a gNB. If the embodiments of the present application are applied to a future communication system, then the network device can correspond to the access network device in the future communication system.

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

[0191] The embodiments of the present application provide a first communication method. Please refer to Figure 3 , which is the flowchart of this method. In the following introduction process, this method is applied to Figure 2 the network architecture shown as an example. In addition, this method can be executed by two communication devices. These two communication devices are, for example, a first communication device and a second communication device. Among them, the first communication device can be a network device or a communication device that can support the network device to implement the functions required for this 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 for this 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 for this 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 for this method. Of course, it can also be other communication devices, such as a chip system. And there are no restrictions 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 for this method, and so on. Among them, the network device is, for example, a base station.

[0192] For the convenience of introduction, in the following, this method is taken as an example of being executed by a network device and a terminal device, that is, taking the first communication device as a network device and the second communication device as a terminal device as an example. If this embodiment is applied to Figure 2 the network architecture shown, therefore, the network device described below can be Figure 2 the network device in the network architecture shown, and the terminal device described below can be Figure 2 the terminal device in the network architecture shown. Other devices described below can be terminal devices. For example, it is in Figure 2A terminal device in a neighboring cell of the serving cell of the terminal device shown, or it can also be a network device, such as Figure 2 other network devices not shown in the figure. The neighboring cell of the serving cell can be Figure 2 provided by the network device shown, or it can also be Figure 2 provided by another network device not shown in the figure.

[0193] S31. The terminal device determines whether the terminal device supports receiving and transmitting other signals in addition to the first reference signal during the measurement process, and the first reference signal is used for the terminal device to perform measurements during the measurement process.

[0194] The first reference signal can be a reference signal for the terminal device to perform measurements. The first reference signal is, for example, SRS, or it can also be other reference signals, such as a channel state information-reference signal (CSI-RS), etc., and there is no specific limitation. There may be multiple reference signals, but only the reference signal used for the terminal device in the embodiments of the present application to perform measurements is called the first reference signal. Correspondingly, it can also be understood that the measurement process described in the embodiments of the present application is the measurement process corresponding to the first reference signal, or rather, during 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 can be called the first device. The first device can be a terminal device, or it can also be a network device, etc., and there is no limitation on the type of the first device.

[0196] For the terminal device, the capability information of the terminal device can be determined. The capability information of the terminal device can indicate various capabilities of the terminal device, and the capability information of the terminal device concerned in the embodiments of the present application is the capability that can indicate whether the terminal device supports receiving and transmitting other signals in addition to the first reference signal during the measurement process. Thus, the terminal device can determine that the terminal device supports receiving and transmitting other signals in addition to the first reference signal during the measurement process, or the terminal device does not support receiving and transmitting other signals in addition to the first reference signal during the measurement process. As for whether the terminal device also determines other capability information of the terminal device, the embodiments of the present application do not make any limitations.

[0197] For example, if the terminal device is affected or significantly affected by other signals transmitted or received during the measurement process in addition to the first reference signal, the capability information may indicate that the terminal device does not support transmitting or receiving other signals during the measurement process in addition to the first reference signal. The measurement process here may refer to CLI measurement or other measurement processes. Additionally, transmitting or receiving other signals during the measurement process in addition to the first reference signal can be understood as receiving other signals during the measurement process in addition to the first reference signal, or transmitting any signal (including the first reference signal and other signals) during the measurement process, or receiving other signals during the measurement process in addition to the first reference signal and transmitting any signal during the measurement process.

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

[0199] S32. The network device determines whether the terminal device supports transmitting or receiving other signals during the measurement process in addition to the first reference signal.

[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 the network device receives the capability information from the terminal device, it can determine whether the terminal device supports transmitting or receiving other signals during the measurement process in addition to the first reference signal according to the capability information. For this, reference can be made to Figure 3 S34 in which the terminal device sends the 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 can indicate whether the terminal device supports transmitting or receiving other signals during the measurement process in addition to the first reference signal. Among them, S34 can occur before S32 and after S31.

[0201] Similarly, the capability information sent by the terminal device to the network device can be information capable of indicating the capability of whether the terminal device supports transmitting or receiving other signals during the measurement process in addition to the first reference signal. As for whether the terminal device also sends other capability information of the terminal device to the network device, the embodiments of the present application do not make limitations.

[0202] S33. When it is determined that the terminal device does not support receiving and transmitting signals other than the first reference signal during the measurement process, the network device only transmits the first reference signal within the first time domain range. Then, the terminal device only receives the first reference signal within the first time domain range. 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. 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. N can be a positive integer.

[0203] Before S32 and after S31, or before S31, the network device can also configure the terminal device to perform measurements. For example, configure the terminal device to perform SRS-RSRP measurements, or configure the terminal device to perform CLI-RSSI measurements, or can also configure the terminal device to perform other measurements. And the network device can configure the time domain symbols for the terminal device to perform measurements. The time domain symbol where the first reference signal configured by the network device for the terminal device to perform measurements 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 receiving and transmitting signals other than the first reference signal during the measurement process, then the network device may not send signals other than the first reference signal to the terminal device within the first time domain range. This can be understood as that the network device can send the first reference signal for measurement (or may not send the first reference signal) to the terminal device within the first time domain range, and can also send signals other than the first reference signal to the terminal device. However, for signals other than the first reference signal, the network device does not expect the terminal device to correctly receive them, and the network device also does not expect the terminal device to send any signals within the first time domain range. Since the network device does not expect the terminal device to send any signals within the first time domain range, one implementation manner of the network device is that the network device may not detect (or described as, receive) any signals from the terminal device within the first time domain range.

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

[0206] If the terminal device determines that it does not support receiving and transmitting signals other than the first reference signal during the measurement process, then the terminal device only receives the first reference signal within the first time domain range. This can be understood as that 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. Or it can also be described as that the terminal device does not expect to receive and transmit signals other than the first reference signal within the first time domain range. Among them, since the terminal device needs to perform measurement within the first time domain range, it can only receive the first reference signal for measurement, such as SRS, within the first time domain range, without receiving signals other than the first reference signal and without sending any signals, so as to avoid the influence of the signal receiving and transmitting process on the measurement process.

[0207] The first time domain symbol is the symbol where the first reference signal for which the network device configures the terminal device to perform measurement is located. Or rather, the first time domain symbol is the time domain symbol where the first reference signal from other devices that the network device configures the terminal device to measure is located. That is to say, the first time domain symbol is the time domain symbol configured by the network device for the terminal 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 network device-configured terminal device for measurement. The measurement mentioned here, for example, is CLI measurement, or it can also be other measurements. The time domain symbol is, for example, an orthogonal frequency division multiplexing (OFDM) symbol.

[0209] Taking the measurement as a CLI measurement as an example, this section describes how a network device configures the first time-domain symbol. If the measurement is a CLI measurement, the first reference signal is sent by other terminal devices. For the network device, it can obtain information such as the uplink-downlink ratio of the cell where other terminal devices are located and the transmission configuration of the reference signal, and thus determine the time-domain symbol for other cell terminal devices to send the first reference signal based on this information. The network device can determine the time-domain symbol for other cell terminal devices to send the first reference signal as the first time-domain symbol. Or, if the network device cannot obtain information such as the uplink-downlink ratio of the cell where other terminal devices are located or the transmission configuration of the reference signal, or the information obtained by the network device is not accurate enough, then the network device can configure the terminal device to receive the first reference signal from other terminal devices on multiple time-domain symbols. That is to say, 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 the information of the first time-domain symbol to the terminal device. After receiving the information of the first time-domain symbol, the terminal device can determine the first time-domain range by considering the timing of other terminal devices based on the first time-domain symbol. For example, for another terminal device that is far away from the terminal device and has a long timing, the terminal device can determine that it needs to start detecting the first reference signal from the other terminal device N time-domain symbols before the first time-domain symbol, and N is, for example, the number of time-domain symbols corresponding to the timing of the other terminal device. That is to say, the terminal device will detect the first reference signal from the other terminal device within the first time-domain range.

[0210] As can be seen from the previous section, although the network device configures the terminal device to perform measurements on the first time-domain symbol, since the other device sending the first reference signal may be a terminal device in an adjacent cell or may be other network devices, etc., the timing of the measurement will be different. For example, it may be advanced relative to the first time-domain symbol configured by the network device. Therefore, when the terminal device performs measurements, it may actually perform measurements 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 means that the terminal device actually performs 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 means that the terminal device actually performs 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 means that the terminal device actually performs measurements on the first time-domain symbol and the second time-domain symbol.

[0212] Therefore, as described in S33, the first time-domain symbol where the first reference signal is located means that the first time-domain symbol is the time-domain symbol configured by the network device for the terminal device to measure the first reference signal, while the time-domain symbol actually measured by the terminal device for the first reference signal is the time-domain symbol included in the first time-domain range.

[0213] It should be noted here that the first time-domain symbol is the symbol configured by the network device for measurement. In the scenario where the terminal device measures the first reference signal, the first reference signal is sent by the transmitting end on the first time-domain symbol. In other possible scenarios, the network device can configure the first time-domain symbol, but there may be no first reference signal for measurement on the first time-domain symbol, and then the terminal device does not perform measurement.

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

[0215] Regarding the value of N, it can be determined by the network device, and after the network device determines it, it can tell the terminal device. For example, the network device determines the value of N and sends a first message to the terminal device, and the first message is used to indicate the value of N, so that the terminal device determines the value of N. Or, the network device may not tell the terminal device 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 amount when the terminal device measures the first reference signal, then the terminal device can determine the value of N according to the maximum value of the timing advance amount 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 value of the timing advance amount when the terminal device measures the first reference signal, then it can also be considered that the two operations of the network device indicating the maximum value of the timing advance amount when the terminal device measures the first reference signal through the first message and indicating the value of N through the first message are equivalent.

[0216] Alternatively, the value of N can also be determined by the terminal device. Further, after determining the value of N, the terminal device can 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 can 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 value (or the maximum value of the timing advance) when the terminal device measures the first reference signal. Then the network device can determine the value of N according to the maximum timing advance value 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 value when the terminal device measures the first reference signal, it can also be considered that the two operations of the terminal device indicating the maximum timing advance value when the terminal device measures the first reference signal through the second message and indicating the value of N through the second message are equivalent.

[0217] Whether the network device determines the value of N or the terminal device determines the value of N, the following determination method can be adopted:

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

[0219] For example, the value of N is pre-configured by the network device for the terminal device, or the value of N is pre-configured in the terminal device, or the value of N can also be specified by the protocol. For example, 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. Or rather, the value of N is related to the sub-carrier spacing of the serving cell of the terminal device.

[0221] Since the length of the time domain symbol is different for different sub-carrier spacings, the number of second time domain symbols included in the first time domain range can be determined according to the sub-carrier spacing of the serving cell of the terminal device.

[0222] 3. The value of N is determined according to the frequency range to which the serving cell of the terminal device belongs. Or rather, the value of N is related to the frequency range to which the serving cell of the terminal device belongs.

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

[0224] Of course, the above division method of frequency is just an example. In practical applications, the frequency can also be divided into more ranges, and the values of N corresponding to different frequency ranges can be different. The division point of 6 GHz is just an example. Even if the frequency is only divided into two ranges, other division points can also be selected. Naturally, the values of N are also just examples, and the specific values are 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, or rather, the value of N is related to the timing advance of the terminal device in the serving cell.

[0226] Regarding the timing advance, it can be understood from the perspective of relative time. The timings defined in the communication protocol are all relative times. Generally, a time reference point is defined in the communication protocol (this time reference point can be the starting moment of the radio 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, and 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] Then the value of N can be determined according to TA. For example, the value of N is equal to the number of symbols corresponding to TA, or the value of N can also be a function of TA. For example, N = k × T, or N = k + T, etc. Here, 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 rather, 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 introduced. Which one is selected in actual application can be determined by the network device or the terminal device, or can also be specified by the protocol. In addition, the embodiment of the present application does 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 protection scope of the embodiment of the present application.

[0231] As described above, the terminal device does not support the sending and receiving of other signals except the first reference signal during the measurement process. Then there is another case where the terminal device may also support the sending and receiving of other signals except the first reference signal during the measurement process. In this case, there are also different further considerations.

[0232] If the terminal device supports sending and receiving other signals in addition to the first reference signal during the measurement process, then 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 receiving beam method or a beam scanning method. If the beam scanning method is used, the receiving beam used by the terminal device during measurement is different from the receiving beam used when receiving data from the service cell. Therefore, when the terminal device is measuring, if the service cell sends a signal to the terminal device, the terminal device cannot receive it.

[0233] Given this situation, if the network device determines that the terminal device supports transmitting 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 beam scanning during this measurement process, then the network device can send the first reference signal to the terminal device within the first time domain range, or can receive the first signal from the terminal device within the first time domain range, or can send the first signal to the terminal device within the first time domain range, or can receive the first signal from the terminal device and send the third signal to the terminal device within the first time domain range. Both the first signal and the third signal are signals other than the first reference signal, and the types of the first signal and the third signal can be the same or different. Correspondingly, if the terminal device determines that the terminal device supports transmitting and receiving signals other than the first reference signal during the measurement process, and the terminal device determines that it does not adopt beam scanning during this measurement process, then the terminal device can receive the first reference signal within the first time domain range, or can send the first signal to the network device within the first time domain range, or can receive the first signal from the network device within the first time domain range, or can send the first signal to the network device and receive the third signal from the network device within the first time domain range. That is to say, if the terminal device supports transmitting and receiving signals other than the first reference signal during the measurement process, and the terminal device does not adopt beam scanning during this measurement process, then in addition to receiving the first reference signal within the first time domain range, the terminal device can also transmit and receive other signals. The transmission and reception processes 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 transmission and reception processes of other signals, and this method can improve communication efficiency.

[0234] Alternatively, if the network device determines that the terminal device supports receiving and transmitting signals other than the first reference signal during the measurement process, and the network device determines that the terminal device uses beam scanning during the measurement process, then 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 follows: the network device can send the first reference signal for measurement to the terminal device within the first time domain range, or it can also not send the first reference signal to the terminal device. However, for signals other than the first reference signal, the network device can refrain from sending any of them to the terminal device. Moreover, the network device can also refrain from receiving any signals from the terminal device within the first time domain range. Correspondingly, if the terminal device determines that it supports receiving and transmitting signals other than the first reference signal during the measurement process, and the terminal device determines that it uses beam scanning during the measurement process, then the terminal device only receives the first reference signal within the first time domain range. This can be understood as follows: 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. Or it can also be described as: the terminal device does not expect to receive and transmit signals other than the first reference signal within the first time domain range. Among them, since the terminal device needs to perform measurements within the first time domain range, it can only receive the first reference signal for measurement, such as SRS, within the first time domain range, without receiving signals other than the first reference signal and without sending any signals, so as to avoid interference to the signal reception and transmission process caused by the measurement process.

[0235] In the embodiments of this application, the impact of the terminal device on data transmission during measurement is clarified, enabling the network device and the terminal device to have a consistent understanding of time domain symbols with scheduling restrictions, and can avoid as much as possible 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 simultaneously, as well as the resulting waste of network resources.

[0236] Next, consider another issue. In the SRS configuration of LTE, a terminal device can send SRS through one antenna port or multiple antenna ports. When a terminal device sends SRS through multiple antenna ports, the cyclic shifts corresponding to the SRS sent through different antenna ports are different, and the difference between different cyclic shifts is: the number of maximum cyclic shifts / the number of antenna ports.

[0237] If a network device configures multiple terminal devices to send SRS on the same comb of the same symbol, the cyclic shifts of the SRSs used by different terminal devices are configured separately by the network device. One terminal device does not know the configuration of the SRS sent by other terminal devices, and there is no restriction when the network device configures the cyclic shifts of the SRSs of different terminal devices. When a terminal device detects an SRS, it needs to use a detection window. It can be understood that for each SRS that the terminal device needs to receive, a corresponding detection window will be set, 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 SRSs configured by the network device. If the minimum difference between the cyclic shifts of the SRSs configured by the network device is smaller, the length of the detection window is smaller. Since the total length of the detection by the terminal device is fixed, the smaller the length of the detection window, the more the number of detection windows. Currently, there is no restriction when the network device configures the cyclic shifts of the SRSs. Therefore, the terminal device can only set the maximum number of detection windows corresponding to the 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 very likely to fall outside the detection window corresponding to the SRS. Then the terminal device cannot detect the SRS within the detection window corresponding to the SRS and will consider the detection to fail. Or it is also possible that the difference between the cyclic shifts of two SRSs is relatively small, and the timings of the two SRSs arriving at the terminal device for measurement are different, which may cause the two SRSs received by the terminal device to overlap. Then the terminal device will only consider that it has received one SRS and consider the other SRS to have a detection failure.

[0238] In view of this, the embodiment of the present application provides a second communication method. Through this method, the problem of detection errors caused by unreasonable setting of the detection window can be solved. Please refer to Figure 4 , which is the flowchart of this method. In the following introduction process, it is assumed that this method is applied to Figure 2Take the network architecture shown as an example. In addition, this method can be executed by two communication devices, such as a first communication device and a second communication device. Among them, the first communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by this method, or the first communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by this method. Of course, it can also be other communication devices, such as a chip system. The same applies to the second communication device. The second communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by this method, or the second communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by this method. Of course, it can also be other communication devices, such as a chip system. And there are no restrictions 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 capable of supporting the terminal device to implement the functions required by this method, and so on. Among them, the network device is, for example, a base station.

[0239] For the sake of convenience in introduction, hereinafter, take the example that this method is executed by a network device and a terminal device, that is, take the example that the first communication device is a network device and the second communication device is a terminal device. If this embodiment is applied to Figure 2 the network architecture shown, therefore, the network device described hereinafter can be Figure 2 the network device in the network architecture shown, and the terminal device described hereinafter can be Figure 2 the terminal device in the network architecture shown. Other devices described hereinafter can be terminal devices, such as terminal devices in the neighboring cells of the serving cell of the terminal device shown in Figure 2 , or can also be network devices, such as other network devices not drawn in Figure 2 . The neighboring cells of the serving cell can be provided by Figure 2 the network device shown, or can also be provided by Figure 2 another network device not drawn in

[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 differences between any two of the multiple cyclic shifts corresponding to the multiple first reference signals configured by the network device is greater than or equal to M. 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 measurements, such as CLI measurements, or other measurements.

[0242] The first reference signal may be a reference signal for the terminal device to perform measurements. The first reference signal is, for example, SRS, or it may also be other reference signals, such as CSI-RS, etc., without specific limitations. There may be multiple reference signals, but only the reference signal used by the terminal device in the embodiments of this application to perform measurements is called the first reference signal. Correspondingly, it can also be understood that the measurement process described in the embodiments of this application is the measurement process corresponding to the first reference signal. Or rather, in the described 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. 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 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 it may also be a network device, etc., without limitations on the type of the first device.

[0244] The first reference signal may be sent in the form of a sequence. Then, the network device may configure a cyclic shift for each first reference signal, and the cyclic shifts corresponding to different first reference signals are different, so that the terminal device can distinguish different first reference signals. Since the cyclic shifts corresponding to different first reference signals are different, there will be a corresponding difference between two cyclic shifts. For multiple first reference signals, multiple cyclic shifts may correspond, and there will be a difference between every two of the first reference signals. Among them, the first reference signal and the cyclic shift may be in a one-to-one correspondence. In the embodiments of this application, among the differences between every two of the multiple cyclic shifts corresponding to the multiple first reference signals configured by the network device, the smallest difference is greater than or equal to M. That is to say, among the multiple cyclic shifts configured by the network device, the difference between any two cyclic shifts needs to be greater than or equal to M. It can be understood that the difference between the cyclic shifts described here may refer to the actual difference between the cyclic shifts or the absolute value of the actual difference between the cyclic shifts.

[0245] For example, the network device configures M = 1. Moreover, the network device configures 4 first reference signals, namely 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 be 2, cyclic shift 2 to be 3, cyclic shift 3 to be 5, and cyclic shift 4 to be 7. Then 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 these 4 first reference signals configured by the network device meet the requirements.

[0246] Regarding the value of M, one of the following methods can be used to determine it:

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

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

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

[0250] 2. The value of M is determined according to the maximum timing error that the terminal device can handle, or rather, 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 normally measure the first reference signal and meet the requirements of the corresponding measurement indicators. 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 according to 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 also 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, where G represents the length of a CP. For a comb, when the number of detection windows corresponding 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 of detection windows corresponding is 8, then the terminal device will set 8 detection windows, each detection window corresponding 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 serving cell of the terminal device belongs, or rather, the value of M is related to the frequency range to which the frequency of the serving cell of the terminal device belongs.

[0254] The frequency can be divided into different ranges. For example, a relatively coarse-grained division method is to divide the frequency into high frequency and low frequency. For example, a frequency greater than or equal to 6 GHz is high frequency, and a frequency less than 6 GHz is low frequency. For high frequency, 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 small, the possibility that the first reference signal falls into the detection window corresponding to other cyclic shifts is small, and the terminal device may still be able to receive the first reference signal from other devices normally. Therefore, in this case, M can be set to be small so that the terminal device can receive as many first reference signals as possible to improve the measurement accuracy. For example, M = 2.

[0255] For low frequencies, the cell radius is relatively large. 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 large. If the terminal device sets the length of the detection window to be small, reception errors may occur. For example, the first reference signal may fall outside the detection window, or multiple first reference signals may be superimposed, etc. Therefore, in this case, M can be set to be large so that the terminal device can improve the measurement accuracy. For example, M = 4.

[0256] Of course, the way of dividing frequencies here is just an example. In actual applications, frequencies can also be divided into more ranges, and the values of N corresponding to different frequency ranges can be different. The division point of 6 GHz is also just an example. Even if the frequencies are only divided into two ranges, other division points can be selected. Naturally, the value of M is also just an example, and the specific value 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 rather, the value of M is related to the subcarrier spacing of the serving cell of the terminal device.

[0258] If the subcarrier spacing is different, the length of the time-domain symbol will also be different. Therefore, the value of M can also be determined according to the subcarrier spacing of the serving cell of the terminal device.

[0259] The above introduces several ways to determine the value of M. In actual applications, which one to choose can be configured by the network device or can also be specified by the protocol. In addition, the embodiments of the present application do not limit the way to determine the value of M. For example, in addition to the above several determination methods, other possible ways to determine the value of M are also within the protection scope 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. The measurement configuration information is used to instruct the terminal device to measure multiple first reference signals.

[0261] After the network device determines the measurement configuration information, it can send the measurement configuration information to the terminal device.

[0262] Among them, the value of M can be determined by the network device, and after determining the value of M, the network device 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. 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. That is, the network device can send 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] Or, 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 again. Whether it is the network device or the terminal device, when determining the value of M, it can adopt one of the several determination methods described in S41, and the determination methods adopted by the network device and the terminal device should be the same, so as to ensure 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 differences between any 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.

[0265] The terminal device expects that the minimum value of the differences between any two of 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 does not initially determine whether the network device has adopted such a configuration. Therefore, the terminal device can first determine whether the minimum value of the differences between any two of the multiple cyclic shifts corresponding to the multiple first reference signals is greater than or equal to M. If the minimum value of the differences between any two of the multiple cyclic shifts corresponding to the multiple first reference signals is less than M, the terminal device can not measure (or it can be described as that the terminal device does not expect (not expected) to measure, or the terminal device does not require (not required) to measure) these multiple first reference signals. That is, as long as one of the differences between any two of the multiple cyclic shifts corresponding to the multiple first reference signals is less than M, the terminal device can not measure these multiple first reference signals.

[0266] If the minimum value of the differences between the cyclic shifts corresponding to multiple first reference signals determined by the terminal device is greater than or equal to M, the terminal device can measure the multiple first reference signals according to the measurement configuration information.

[0267] If no limit is imposed on the minimum difference of cyclic shifts, then the terminal device can only detect in the worst-case scenario, that is, the detection window corresponding to each cyclic shift is the time resolution of a single cyclic shift (minimum 1 / 48 time domain symbols). This may cause the terminal device to miss or misdetect the first reference signal, reducing the measurement accuracy. By means of the method provided in the embodiments of the present application, the minimum distance between the cyclic shifts of multiple first reference signals on the same time domain symbol and the same comb is defined, and the terminal device can correspondingly adjust the size of the detection window corresponding to each cyclic shift during detection, so that the measured first reference signal can fall into the corresponding detection window as much as possible, improving the measurement accuracy.

[0268] Or, to solve the same problem as the Figure 4 problem to be solved by the embodiment shown, the embodiments of the present application provide a third communication method. By means of this method, the problem of detection errors caused by unreasonable detection window settings can be solved. Please refer to Figure 5 , which is the flowchart of this method. In the following introduction, this method is applied to the Figure 2 network architecture shown as an example. In addition, this method can be executed by two communication devices. These two communication devices are, for example, a first communication device and a second communication device. Among them, the first communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by this method, or the first communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by this method. Of course, it can also be other communication devices, such as a chip system. The same applies to the second communication device. The second communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by this method, or the second communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by this method. Of course, it can also be other communication devices, such as a chip system. And no limitation is imposed on the implementation manners 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 capable of supporting the terminal device to implement the functions required by this method, and so on. Among them, the network device is, for example, a base station.

[0269] For ease of introduction, in the following text, it is assumed that this method is executed by a network device and a terminal device. That is, it is assumed that the first communication device is a network device and the second communication device is a terminal device. If this embodiment is applied to Figure 2 the network architecture shown, therefore, the network device described in the following text can be Figure 2 the network device in the network architecture shown, and the terminal device described in the following text can be Figure 2 the terminal device in the network architecture shown. Other devices described in the following text can be terminal devices. For example, they can be terminal devices in the neighboring cells of the serving cell of the terminal device shown in Figure 2 , or they can also be network devices. For example, they can be Figure 2 other network devices not drawn in. The neighboring cells of the serving cell can be provided by the network device shown in Figure 2 , or they can also be provided by Figure 2 another network device not drawn in.

[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 no 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 can be a reference signal for the terminal device to perform measurements. The first reference signal is, for example, SRS, or it can also be other reference signals, such as CSI-RS, etc., without specific limitation. There may be multiple reference signals, but only the reference signals used by the terminal device in the embodiments of this application to perform measurements are called first reference signals. Correspondingly, it can also be understood that the measurement process described in the embodiments of this application corresponds to the first reference signal, or rather, during the described 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. 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 can be sent by the first device. Of course, if there are multiple first reference signals, the multiple first reference signals can come from at least one first device. The first device can be a terminal device, or it can also be a network device, etc. There is no limitation on the type of the first device.

[0273] Among the multiple first reference signals indicated by the measurement configuration information, there are no 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 can configure the terminal device to perform measurements, such as CLI measurements, or it can also be other measurements. The first reference signal is, for example, SRS, or it can also be other reference signals, such as CSI-RS, etc., without specific limitations. The first reference signal can be sent by the first device. Of course, if there are multiple first reference signals, the multiple first reference signals can come from at least one first device.

[0275] The first device can be a terminal device, or it can also be a network device, etc., without limitations on the type of the first device.

[0276] As introduced above, if the network device configures multiple terminal devices to send SRS on the same comb of the same symbol, the cyclic shifts of the SRSs used by different terminal devices are configured separately by the network device. A terminal device does not know the configuration of the SRSs sent by other terminal devices, and there are no restrictions when the network device configures the cyclic shifts of the SRSs of different terminal devices. This results in the terminal device having to set the detection window according to the maximum number, and the length of the detection window is small, resulting in a greater possibility of the terminal device misdetecting or missing the reference signal bandwidth. Therefore, in the embodiments of this application, among the multiple first reference signals configured by the network device, there are no two first reference signals located on the same time domain symbol and corresponding to the same comb. That is to say, 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 both the time domain symbols and the corresponding combs of any two reference signals are different. In this way, the possible problems are avoided, and the detection accuracy of the terminal device is improved.

[0277] For example, a network device is configured with 4 first reference signals, namely first reference signal 1, first reference signal 2, first reference signal 3, and first reference signal 4. Among them, 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 the combs corresponding to first reference signal 1 and first reference signal 3 are the same, the corresponding time domain symbols are different, and although the time domain symbols corresponding to first reference signal 2 and first reference signal 3 are the same, the corresponding combs are different. That is to say, there are no two first reference signals located on the same time domain symbol and corresponding to the same comb.

[0278] As an optional implementation manner, in addition to indicating that the terminal device measures multiple first reference signals, the measurement configuration information may also indicate that the terminal device measures multiple second reference signals, and the multiple second reference signals are located on the same time domain symbol and correspond to the same comb.

[0279] The second reference signal may also be a reference signal for the terminal device to perform measurements. The second reference signal is, for example, SRS, or it may also be other reference signals, such as CSI-RS, etc., and specific ones are not limited. There may be multiple reference signals, but only the reference signals for the terminal device to perform measurements in the embodiments of the present application are called first reference signals or second reference signals. Or rather, in the described measurement process, the terminal device needs to measure first reference signals, or measure first reference signals and second reference signals.

[0280] The second reference signal may be sent by a second device. Of course, if there are multiple second reference signals, the multiple second reference signals may come from at least one second device. The second device may be a terminal device, or it may also be a network device, etc., and the type of the second device is not limited. Moreover, the type of the first device and the type of the second device may be the same, for example, both are terminal devices, or the type of the first device and the type of the second device may also be different, for example, the first device is a terminal device and the second device is a network device. In addition, for the same device, it may be able to send both first reference signals and second reference signals, then this device can be both the first device and the second device.

[0281] For example, the network device is also configured with two second reference signals, namely the second reference signal 1 and the second reference signal 2. Among them, the second reference signal 1 corresponds to time domain symbol 1, the second reference signal 2 corresponds to time domain symbol 1, the second reference signal 1 corresponds to comb1, and the second reference signal 2 also corresponds to comb1. It can be seen that the time domain symbols corresponding to the second reference signal 1 and the second reference signal 2 are the same, and the corresponding combs are also the same.

[0282] 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. The measurement configuration information is used to instruct the terminal device to measure multiple reference signals.

[0283] After determining the measurement configuration information, the network device can send the measurement configuration information to the terminal device.

[0284] S53. When the terminal device determines that there are no 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.

[0285] Among them, when the terminal device determines that among the multiple first reference signals, there are no at least two first reference signals that are located on the same time domain symbol and correspond to the same comb, it can also be described as that when the terminal device determines the time domain symbol where each first reference signal is located and the corresponding comb, there are no other first reference signals.

[0286] The terminal device expects that there are no at least two first reference signals among the multiple first reference signals configured by the network device that are located on the same time domain symbol and correspond to the same comb. However, initially, the terminal device is not sure whether the network device has adopted such a configuration. Therefore, the terminal device can first determine whether there are no 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. If the terminal device determines that there are no 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, the terminal device can measure the multiple reference signals according to the measurement configuration information.

[0287] If the network device is also configured with multiple second reference signals through measurement configuration information, then the terminal device can determine whether there are at least two second reference signals among the multiple second reference signals that are not 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 on the same time domain symbol and correspond to the same comb, the determination result of the terminal device is also that the multiple second reference signals are on the same time domain symbol and correspond to the same comb. Then the terminal device can not measure the multiple second reference signals to reduce the measurement error.

[0288] Through the method provided by the embodiments of the present application, there are no two first reference signals among the multiple first reference signals configured by the network device on the same time domain symbol and corresponding to the same comb, which fundamentally solves the reason for the problem of misdetection or missed detection of reference signals by the terminal device, and helps to improve the measurement accuracy of the terminal device.

The processor is mainly used to process communication protocols and communication data, control the terminal device, execute software programs, process data of software programs, etc. The memory is mainly used to store software programs and data. The radio frequency circuit is mainly used for the conversion between baseband signals and radio frequency signals and the processing of radio frequency signals. The antenna is mainly used to transmit and receive radio frequency signals in the form of electromagnetic waves. The input / output device, such as a touch screen, a display screen, a keyboard, etc., is mainly used to receive data input by the user and output data to the user. It should be noted that some types of terminal devices may not have an input / output device.

[0352] When data needs to be sent, after the processor performs baseband processing on the data to be sent, it outputs a baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then sends the radio frequency signal outwards in the form of electromagnetic waves through the antenna. When data is sent to the terminal device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data. For the sake of convenience of description, Figure 18 only one memory and one processor are shown in the figure.
