Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a reference signal processing method, apparatus, terminal and medium. Background Technology

[0002] Currently, in unlicensed communication systems, network-side equipment can employ Directional Listen Before Talk (Directional LBT) to monitor channels in a specific beam direction of the unlicensed spectrum. When the channel is determined to be idle, the network-side equipment can access it and transmit data (e.g., reference signals) to the User Equipment (UE) through the channel during the Channel Occupancy Time (COT). The UE can then receive the reference signals transmitted by the network side for Radio Link Monitoring (RLM).

[0003] However, since the channel may be busy in the direction of the transmitted reference signal beam, the network-side equipment may fail to transmit the Directional LBT in the direction of the transmitted reference signal, and the reference signal cannot be transmitted. At this time, the UE is still receiving the reference signal and performing RLM in that beam direction. Therefore, the accuracy of the RLM result performed by the UE based on the reference signal is poor.

[0004] This results in poor communication quality for the UE. Summary of the Invention

[0005] This application provides a reference signal processing method, apparatus, terminal, and medium that can solve the problem of poor communication quality of UE.

[0006] In a first aspect, a reference signal processing method is provided, comprising: a UE receiving target indication information from a network-side device; and the UE performing a target operation when a preset condition is met between a first spatial range and a target spatial range; wherein the first spatial range is obtained based on the spatial range of a first channel or based on the spatial indication information; the first channel is a channel carrying the target indication information; the spatial indication information is indication information included in the target indication information; the target spatial range is the spatial range of a reference signal configured by the network-side device; and the target operation includes at least one of the following: receiving a reference signal from the network-side device and measuring the reference signal.

[0007] Secondly, a reference signal processing apparatus is provided, comprising a receiving module and an execution module. The receiving module is configured to receive target indication information from a network-side device. The execution module is configured to perform a target operation when preset conditions are met between a first spatial range and a target spatial range. The first spatial range is obtained based on the spatial range of a first channel or based on spatial indication information; the first channel is a channel carrying target indication information, the spatial indication information being indication information included in the target indication information; the target spatial range is the spatial range of a reference signal configured by the network-side device; the target operation includes at least one of the following: receiving a reference signal from the network-side device and measuring the reference signal.

[0008] Thirdly, a terminal is provided, the terminal including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the method described in the first aspect.

[0009] Fourthly, a terminal is provided, including a processor and a communication interface, wherein the communication interface is used to receive target indication information from a network-side device. The processor is used to perform a target operation when preset conditions are met between a first spatial range and a target spatial range. The first spatial range is obtained based on the spatial range of a first channel or based on spatial indication information; the first channel is a channel carrying target indication information, the spatial indication information being indication information included in the target indication information; the target spatial range is the spatial range of a reference signal configured by the network-side device; the target operation includes at least one of the following: receiving the reference signal from the network-side device and measuring the reference signal.

[0010] Fifthly, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0011] In a sixth aspect, a chip is provided, the chip including a processor and a communication interface coupled to the processor, the processor being used to run programs or instructions to implement the steps of the method described in the first aspect.

[0012] In a seventh aspect, a computer program / program product is provided, the computer program / program product being stored in a non-volatile storage medium, the program / program product being executed by at least one processor to perform the steps of the method as described in the first aspect.

[0013] In this embodiment of the application, the UE can receive target indication information from the network-side device to obtain a first spatial range based on the spatial range of the first channel carrying the target indication information (or the spatial indication information included in the target indication information), and then determine whether the first spatial range and the target spatial range of the reference signal configured by the network-side device meet a preset condition. If it is determined that the first spatial range and the target spatial range meet the preset condition, the UE can receive the reference signal from the network-side device and / or measure the reference signal. Since the UE can first receive target indication information from the network-side device to obtain the first spatial range of the signal to be transmitted by the network-side device, the UE can determine whether the first spatial range of the signal to be transmitted meets the preset conditions with the target spatial range of the reference signal transmitted by the network-side device through a channel in a certain beam direction. This allows the UE to determine whether the beam range of the signal to be transmitted covers the beam range of the reference signal transmitted through a channel in a certain beam direction. If the beam range of the signal to be transmitted covers the beam range of the reference signal transmitted through a channel in a certain beam direction, the UE can receive the reference signal from the network-side device and / or measure the reference signal for RLM. Therefore, this avoids the problem of the UE still receiving the reference signal and performing RLM in the beam direction when the network-side device fails the Directional LBT in the beam direction of the reference signal transmission and the reference signal cannot be transmitted. This improves the accuracy of the RLM result performed by the UE based on the reference signal, thereby improving the UE's communication quality. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] 1. Unauthorized communication systems

[0025] Unlicensed bands can supplement licensed bands to help operators expand service capacity. Because unlicensed bands are shared by multiple technologies (Radio Access Technology, RATs), such as Wi-Fi, radar, and LTE-LAA, in some countries or regions, their use must comply with regulations to ensure fair sharing of the resource by all communication devices. These regulations include requirements such as Listen Before Talk (LBT) and Maximum Channel Occupancy Time (MCOT).

[0026] When a communication device needs to send information, it must first perform LBT on a designated channel to perform energy detection (ED) on the surrounding wireless transmission environment. When the detected energy value is lower than a preset threshold, the channel is judged to be idle, and transmission can only be carried out through the channel at this time. The channel time occupied by the transmission cannot exceed MCOT. Conversely, the channel is judged to be busy, and transmission cannot be carried out through the channel at this time.

[0027] The communication equipment can be network-side equipment, UE, Wireless-Fidelity Access Point (Wi-FiAP), etc.

[0028] 2. LBT

[0029] Commonly used LBT types (category) can be divided into category 1, category 2 and category 4.

[0030] For Category 1: LBT means that the sender does not perform LBT, i.e., no LBT or immediate transmission.

[0031] For Category 2: LBT is a one-shot LBT, meaning the sender performs an LBT before transmission. If the sender detects that the channel is idle, it will transmit through that channel; if the sender detects that the channel is busy, it will not transmit through that channel.

[0032] For Category 4: LBT is a back-off channel listening mechanism. When the transmitter detects that the channel is busy, it backs off and continues listening until the channel is empty.

[0033] Currently, in the unlicensed frequency band of 57-71GHz, considering the impact of beamforming and the issue of hidden nodes, LBT is further divided into the following methods:

[0034] (Quasi-)Omni-directional LBT: Power detection is performed using an omnidirectional or quasi-omnidirectional receiving antenna, which is the traditional LBT method;

[0035] Directional LBT: Power detection is performed using a directional receiving antenna;

[0036] Wide-beam LBT: LBT is performed before COT begins using a wide sensing beam that can cover all transmitted beams. It should be noted that the definition of "cover" is still under discussion.

[0037] Per-beam LBT: Before COT begins, LBT is performed for each transmit beam separately.

[0038] 3. Transmission Configuration Indicator (TCI) Status

[0039] Network-side equipment can use Radio Resource Control (RRC) signaling to configure one or more TCI states for each control resource set (CORESET). When multiple TCI states are configured, a TCI state can be indicated or activated by the Media Access Control (MAC) control element (CE). In this way, when a UE is listening to a channel in a certain beam direction, it can use the same quasi-colocation (QCL), i.e., the same TCI state, to listen to that channel across the entire search space within the CORESET. In other words, the UE can determine which receive beam to use to receive the channel based on the TCI state.

[0044] The reference signal processing method, apparatus, terminal, and medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0045] Figure 2 A flowchart of a reference signal processing method provided in an embodiment of this application is shown. Figure 2As shown, the reference signal processing method provided in this application embodiment may include the following steps 101 and 102.

[0046] Step 101: The UE receives target indication information from the network-side device.

[0047] Optionally, in this embodiment of the application, the aforementioned target indication information may specifically be: COT indication information. Specifically, the COT indication information may be: Downlink Control Information (DCI), and the format of the DCI may be DCI 2_0.

[0048] Optionally, in this embodiment of the application, the target indication information may include: the time domain range of COT and the frequency domain range of COT.

[0049] Optionally, in this embodiment of the application, the network-side device may include a reference signal among the signals it can transmit during the channel occupancy time.

[0050] The reference signal may include at least one of the following: Synchronous signal and PBCH block (SSB), Time Reference Signal (TRS), Channel State Information Reference Signal (CSI-RS), Demodulation Reference Signal (DMRS), etc.

[0051] In this embodiment of the application, the first spatial range is obtained based on the spatial range of the first channel or based on spatial indication information; the first channel is a channel carrying target indication information, and the spatial indication information is the indication information included in the target indication information.

[0052] It is understandable that the UE can obtain the first spatial range through the first channel, or it can obtain the first spatial range from the target indication information.

[0053] If the UE can obtain the first spatial range from the target indication information, the target indication information also includes the first spatial range, that is, the target indication information includes: the time domain range of COT, the frequency domain range of COT and the first spatial range.

[0054] Further optionally, in the embodiments of this application, the first channel can be any of the following: Physical downlink control channel (PDCCH), Physical downlink shared channel (PDSCH), etc.

[0055] Step 102: If the preset conditions are met between the first airspace range and the target airspace range, the UE performs the target operation.

[0056] In this embodiment of the application, the target airspace range is: the airspace range of the reference signal configured by the network-side device.

[0057] Optionally, in this embodiment, the reference signal may specifically be a reference signal transmitted by the network-side device through a channel in the direction of the target beam. The UE can receive the relevant configuration of the reference signal from the network-side device, which includes the spatial range of the reference signal, so that the UE can determine whether the first spatial range and the target spatial range meet preset conditions.

[0058] Optionally, in this embodiment of the application, the above-mentioned preset conditions include: the target airspace range is within the first airspace range.

[0059] Further, optionally, in this embodiment of the application, the above-mentioned preset conditions may specifically include one or more of the following:

[0060] The time domain range of the reference signal is within the time domain range of the COT;

[0061] The frequency domain range of the reference signal is within the frequency domain range of the COT;

[0062] The target airspace is within the first airspace.

[0063] In this embodiment of the application, the target operation includes at least one of the following: receiving a reference signal from a network-side device and measuring the reference signal.

[0064] In this embodiment of the application, if the first spatial range and the target spatial range meet the preset conditions, it can be considered that the first spatial range that the network-side device can transmit covers the target spatial range of the reference signal transmitted through the channel in a certain beam direction. Therefore, the UE can receive the reference signal from the network-side device and / or measure the reference signal.

[0065] This application provides a reference signal processing method in which a UE can receive target indication information from a network-side device, obtain a first spatial range based on the spatial range of a first channel carrying the target indication information (or the spatial indication information included in the target indication information), and then determine whether the first spatial range and the target spatial range of a reference signal configured by the network-side device meet a preset condition. If the preset condition is met, the UE can receive the reference signal from the network-side device and / or measure the reference signal. Since the UE can first receive target indication information from the network-side device to obtain the first spatial range of the signal to be transmitted by the network-side device, the UE can determine whether the first spatial range of the signal to be transmitted meets the preset conditions with the target spatial range of the reference signal transmitted by the network-side device through a channel in a certain beam direction. This allows the UE to determine whether the beam range of the signal to be transmitted covers the beam range of the reference signal transmitted through a channel in a certain beam direction. If the beam range of the signal to be transmitted covers the beam range of the reference signal transmitted through a channel in a certain beam direction, the UE can receive the reference signal from the network-side device and / or measure the reference signal for RLM. Therefore, this avoids the problem of the UE still receiving the reference signal and performing RLM in the beam direction when the network-side device fails the Directional LBT in the beam direction of the reference signal transmission and the reference signal cannot be transmitted. This improves the accuracy of the RLM result performed by the UE based on the reference signal, thereby improving the UE's communication quality.

[0066] The following will illustrate this with four different examples.

[0067] For Example 1 and Example 2:

[0068] Optionally, in this embodiment of the application, the first spatial domain range is obtained based on the spatial domain range of the first channel; the first spatial domain range includes at least one of the following:

[0069] The transmit beam range of the first quasi-co-located QCL source reference signal;

[0070] The transmission beam range of the first channel;

[0071] In this embodiment of the application, the first QCL source reference signal is: a first type of QCL source reference signal corresponding to the transmission configuration indication (TCI) state of the first channel.

[0072] In this embodiment of the application, before the network-side device sends target indication information to the UE through the first channel, the network-side device may send the relevant configuration of the beam of the first channel to the UE, so that the UE can determine the first QCL source reference signal according to the TCI state in the relevant configuration, and / or determine the transmission beam range of the first channel according to the beam range in the relevant configuration.

[0073] Example 1:

[0074] Optionally, in this embodiment of the application, the first spatial domain range includes: the transmission beam range of the first QCL source reference signal; the target spatial domain range is within the first spatial domain range, including any one of the following:

[0075] The reference signal and the first QCL source reference signal have a first QCL relationship;

[0076] The reference signal and the first QCL source reference signal have a second QCL relationship.

[0077] Further optionally, in the embodiments of this application, the first QCL relationship can be a direct Type D QCL relationship; the second QCL relationship can be an indirect Type D QCL relationship.

[0078] It is understandable that the UE can determine whether the target spatial range is within the first spatial range by determining whether there is a direct or indirect Type D QCL relationship between the reference signal and the first QCL source reference signal.

[0079] In this embodiment of the application, the reference signal and the first QCL source reference signal have a first QCL relationship, including any one of the following:

[0080] The reference signal is the same as the first QCL source reference signal, and the target QCL source reference signal is the same as the first QCL source reference signal.

[0081] In this embodiment of the application, the target QCL source reference signal is: the first type of QCL source reference signal corresponding to the TCI state of the reference signal.

[0082] Further optionally, in the embodiments of this application, the relevant configuration of the beam in the target beam direction may include the TCI state of the reference signal, so that the UE can determine the target QCL source reference signal according to the relevant configuration.

[0083] In this embodiment of the application, the reference signal and the first QCL source reference signal have a second QCL relationship, including:

[0084] The second QCL source reference signal is the same as the first QCL source reference signal.

[0085] In this embodiment of the application, the second QCL source reference signal is: the Nth level QCL source reference signal of the first type of reference signal; N is a positive integer greater than 1.

[0086] Further optionally, in this embodiment of the application, the first type can specifically be: Type D.

[0087] Further optionally, in this embodiment, the TCI state of the reference signal may include multiple types, each type corresponding to at least one QCL source reference signal. Thus, the UE can first determine the QCL source reference signal 1 corresponding to the first type in the TCI state of the reference signal. Reference signal 1 is the first-level QCL source reference signal of the first type of the reference signal. The TCI state of reference signal 1 may include multiple types, each type corresponding to at least one QCL source reference signal. Then, the UE can determine the QCL source reference signal 2 corresponding to the first type in the TCI state of reference signal 1. Reference signal 2 is the second-level QCL source reference signal of the first type of the reference signal. The TCI state of reference signal 2 may include multiple types, each type corresponding to at least one QCL source reference signal. Next, the UE can determine the QCL source reference signal 3 corresponding to the first type in the TCI state of reference signal 2. Reference signal 3 is the third-level QCL source reference signal of the first type of the reference signal. The TCI state of reference signal 3 may include multiple types, each type corresponding to at least one reference signal, and so on.

[0088] For example, such as Figure 3 As shown, assuming the reference signal is CSI-RS5, the first QCL source reference signal is SSB1, and the Type D of CSI-RS5...

[0089] The first-level QCL source reference signal is CSI-RS4, and the Type D QCL source reference signal of CSI-RS4 is CSI-RS1. Then, the Type D second-level QCL source reference signal of CSI-RS5 is CSI-RS1, and so on. The Type D third-level QCL source reference signal of CSI-RS5 is SSB1. That is, the Type D third-level QCL source reference signal of CSI-RS5 is the same as the first QCL source reference signal. Thus, it can be considered that there is an indirect Type D QCL relationship between the reference signal and the first QCL source reference signal.

[0090] Example 2:

[0091] Optionally, in this embodiment of the application, the first spatial domain range includes: the transmission beam range of the first channel; the target spatial domain range within the first spatial domain range includes:

[0092] The reference signal and the first channel have a third QCL relationship.

[0093] Further optionally, in the embodiments of this application, the third QCL relationship can specifically be: a direct or indirect Type EQCL relationship.

[0094] Optionally, in this embodiment of the application, the reference signal and the first channel have a third QCL relationship, including:

[0095] The transmission direction referenced by the target QCL source is covered within the transmission direction of the first channel.

[0096] In this embodiment of the application, the target QCL source reference includes at least one of the following: the bearer channel of the target signal and the third QCL source reference signal; the target QCL source reference is determined based on the second type of QCL information corresponding to the TCI state of the reference signal.

[0097] Further optionally, in the embodiments of this application, the target QCL source reference can be any of the following: CSI-RS, SSB, signal bearer channel, etc.

[0098] Further optionally, in this embodiment of the application, the second type can specifically be: Type E.

[0099] It is understandable that the UE can determine whether the target airspace range is within the first airspace range by determining whether the transmission direction of the target QCL source reference covers the transmission direction of the first channel.

[0100] Optionally, in the embodiments of this application, the QCL information includes at least one of the following:

[0101] Service area signage;

[0102] Bandwidth portion BWP;

[0103] QCL source reference;

[0104] QCL type.

[0105] In this embodiment of the application, the QCL source reference includes at least one of the following: the signal carrying channel and the QCL source reference signal.

[0106] Further optionally, in the embodiments of this application, the UE may determine the bearer channel of the signal in the QCL source reference as the bearer channel of the target signal; and / or determine the QCL source reference signal in the QCL source reference as the third QCL source reference signal, so as to determine the target QCL source reference.

[0107] For Examples 3 and 4:

[0108] Optionally, in this embodiment of the application, the first airspace range is obtained based on airspace indication information. Specifically, in conjunction with... Figure 2 ,like Figure 4 As shown, step 101 above can be specifically implemented through step 101a below.

[0109] Step 101a: The UE receives control information from the network-side device and parses the control information according to the target parameters to obtain target indication information, thereby obtaining airspace indication information.

[0110] Further optionally, in this embodiment of the application, the control information may specifically be: DCI, and the format of the DCI may be DCI 2_0.

[0111] Optionally, in the embodiments of this application, the target parameter includes at least one of the following:

[0112] Service area signage;

[0113] Position information in the DCI (Discretionary Airspace Indication) system;

[0114] Target list.

[0115] Thus, since the UE can parse the control information to obtain the airspace indication information and determine the first airspace range without needing to determine the first airspace range based on other information, the time spent determining the first airspace range can be reduced.

[0116] Optionally, in this embodiment of the application, the first airspace range includes at least one of the following:

[0117] The transmission beam range of the M first reference signals;

[0118] The transmission beam range of the Q second reference signals.

[0119] In this embodiment of the application, the M first reference signals are: reference signals indicated by the airspace indication information, or reference signals in the reference signal group indicated by the airspace indication information.

[0120] Further optionally, in the embodiments of this application, the airspace indication information may indicate the identifiers of M first reference signals to indicate M first reference signals; or, it may indicate the identifiers of at least one reference signal group to indicate M first reference signals.

[0121] In this embodiment, the Q second reference signals are: QCL source reference signals of the first type corresponding to the target TCI state; the target TCI state is: the TCI state indicated by the spatial indication information, or the TCI state in the TCI group indicated by the spatial indication information; M and Q are both positive integers.

[0122] Further optionally, in the embodiments of this application, the airspace indication information may indicate the identifier of the target TCI state to indicate the target TCI state; or, it may indicate the identifier of at least one TCI group to indicate the target TCI state.

[0123] Example 3:

[0124] Optionally, in this embodiment of the application, the first spatial domain range includes: the transmission beam range of the M first reference signals; the target spatial domain range is within the first spatial domain range, including any one of the following:

[0125] There is a first QCL relationship between the reference signal and the T first reference signals;

[0126] There is a second QCL relationship between the reference signal and the T first reference signals.

[0127] In this embodiment of the application, the T first reference signals are: the first reference signal among the M first reference signals; T is a positive integer.

[0128] It is understandable that the UE can determine whether the target spatial domain is within the first spatial domain by determining whether there is a specific direct or indirect Type D QCL relationship between the reference signal and the T first reference signals.

[0129] In this embodiment of the application, the reference signal and the T first reference signals have a first QCL relationship, including any one of the following:

[0130] The reference signal is the same as the T first reference signals, and the target QCL source reference signal is the same as the T first reference signals.

[0131] In this embodiment of the application, the target QCL source reference signal is: the first type of QCL source reference signal corresponding to the TCI state of the reference signal.

[0132] In this embodiment of the application, the reference signal and the T first reference signals have a second QCL relationship, including:

[0133] The second QCL source reference signal is the same as the T first reference signals.

[0134] In this embodiment of the application, the second QCL source reference signal is: the Nth level QCL source reference signal of the first type of reference signal; N is a positive integer greater than 1.

[0135] Optionally, in this embodiment of the application, the first spatial domain range includes the transmission beam range of M first reference signals; wherein, when the M first reference signals are reference signals indicated by spatial domain indication information, the target list is a reference signal list.

[0136] It is understood that the target reference includes at least one of the following:

[0137] Service area signage;

[0138] Position information in the DCI (Discretionary Airspace Indication) system;

[0139] Reference signal list.

[0140] Optionally, in this embodiment of the application, when the M first reference signals are reference signals in the reference signal group indicated by the spatial domain indication information, the target list is the QCL source reference signal group list.

[0141] It is understood that the target reference includes at least one of the following:

[0142] Service area signage;

[0151] The reference signal and the R second reference signals have a second QCL relationship.

[0152] In this embodiment of the application, the R second reference signals are: the second reference signals among the Q second reference signals; R is a positive integer.

[0153] It is understandable that the UE can determine whether the target spatial domain is within the first spatial domain by determining whether there is a specific direct or indirect Type D QCL relationship between the reference signal and the R second reference signals.

[0154] In this embodiment of the application, the reference signal and the R second reference signals have a first QCL relationship, including any one of the following:

[0155] The reference signal is the same as R second reference signals, and the target QCL source reference signal is the same as R second reference signals.

[0157] In this embodiment of the application, the reference signal and the R second reference signals have a second QCL relationship, including:

[0158] The second QCL source reference signal is the same as the R second reference signals.

[0159] In this embodiment of the application, the second QCL source reference signal is: the Nth level QCL source reference signal of the first type of reference signal; N is a positive integer greater than 1.

[0160] Optionally, in this embodiment of the application, the first spatial domain range includes the transmission beam range of Q second reference signals; wherein, when the target TCI state is the TCI state indicated by the spatial domain indication information, the target list is a TCI state list.

[0173] Optionally, in the embodiments of this application, combined with Figure 2 ,like Figure 5 As shown, step 102 above can also be replaced by step 103.

[0174] Step 103: If the preset conditions are not met between the first airspace range and the target airspace range, the UE cancels the execution of the target operation.

[0175] Further, optionally, in the embodiments of this application, the preset conditions may specifically include one or more of the following:

[0176] The time domain range of the reference signal is not within the time domain range of the COT;

[0177] The frequency domain range of the reference signal is not within the frequency domain range of the COT;

[0178] The target airspace is not within the first airspace.

[0179] It should be noted that the method for determining the target airspace range when it is not within the first airspace range can refer to the method for determining the target airspace range when it is within the first airspace range, and will not be repeated here in the embodiments of this application.

[0180] In this embodiment of the application, if the first spatial range and the target spatial range do not meet the preset conditions, it can be considered that the reference signal sent through the channel in a certain beam direction cannot be transmitted within the channel occupancy time that the network-side device can transmit. Therefore, the UE can cancel receiving the reference signal from the network-side device and / or cancel measuring the reference signal.

[0181] Thus, since the UE can cancel receiving the reference signal from the network-side device and / or cancel measuring the reference signal if it determines that the beam range of the transmission to be sent by the network-side device does not cover the beam range of the reference signal transmitted through the channel in a certain beam direction, the UE can avoid the problem of the UE still receiving the reference signal and performing RLM in that beam direction when the network-side device fails the Directional LBT in the beam direction in which the reference signal is transmitted and the reference signal cannot be transmitted. In this way, the communication quality of the UE can be improved.

[0182] It should be noted that the reference signal processing method provided in this application embodiment can be executed by a UE, or by a control module in the UE for executing the reference signal processing method.

[0201] The reference signal processing apparatus provided in this application embodiment can first receive target indication information from the network-side device to obtain the first spatial range of the signal to be transmitted by the network-side device. This allows the reference signal processing apparatus to determine whether the first spatial range of the signal to be transmitted satisfies a preset condition with the target spatial range of a reference signal transmitted by the network-side device through a channel in a certain beam direction. This determines whether the beam range of the signal to be transmitted covers the beam range of the reference signal transmitted through a channel in a certain beam direction. If the beam range of the signal to be transmitted covers the beam range of the reference signal transmitted through a channel in a certain beam direction, the reference signal processing apparatus can receive the reference signal from the network-side device and / or measure the reference signal for RLM. Therefore, it avoids the problem of the reference signal processing apparatus still receiving the reference signal and performing RLM in the beam direction where the network-side device fails to transmit the reference signal due to a failure of the Directional LBT in the beam direction. This improves the accuracy of the RLM result performed by the reference signal, thereby enhancing the communication quality of the reference signal processing apparatus.

[0209] In this embodiment, the radio frequency unit 101 receives downlink data from the network-side device and processes it for the processor 110; additionally, it sends uplink data to the network-side device. Typically, the radio frequency unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, etc.

It is understood that the aforementioned modem processor may also not be integrated into processor 110.

[0212] The radio frequency unit 101 is used to receive target indication information from the network-side device.

[0213] The processor 110 is used to perform target operations when preset conditions are met between the first airspace range and the target airspace range.

[0214] Wherein, the first spatial range is obtained based on the spatial range of the first channel or based on spatial indication information; the first channel is a channel carrying target indication information, and the spatial indication information is the indication information included in the target indication information; the target spatial range is the spatial range of the reference signal configured by the network-side device; the target operation includes at least one of the following: receiving the reference signal from the network-side device and measuring the reference signal.

[0215] The terminal provided in this application embodiment can first receive target indication information from the network-side device to obtain the first spatial range of the signal to be transmitted by the network-side device. This allows the terminal to determine whether the first spatial range of the signal to be transmitted satisfies a preset condition with the target spatial range of a reference signal transmitted by the network-side device through a channel in a certain beam direction. This determines whether the beam range of the signal to be transmitted covers the beam range of the reference signal transmitted through the channel in a certain beam direction. If the beam range of the signal to be transmitted covers the beam range of the reference signal transmitted through the channel in a certain beam direction, the terminal can receive the reference signal from the network-side device and / or measure the reference signal for RLM. Therefore, this avoids the problem of the terminal still receiving the reference signal and performing RLM in the beam direction where the network-side device fails to transmit the reference signal, thus improving the accuracy of the RLM result based on the reference signal and enhancing the terminal's communication quality.

[0216] Optionally, in this embodiment of the application, the first airspace range is obtained based on airspace indication information.

[0217] The radio frequency unit 101 is specifically used to receive control information from network-side devices.

[0218] The processor 110 is also used to parse the control information according to the target parameters to obtain target indication information.

[0219] Thus, since the terminal can parse the control information to obtain the airspace indication information and determine the first airspace range without relying on other information, the time spent determining the first airspace range can be reduced.

[0220] Optionally, in this embodiment of the application, the processor 110 is further configured to cancel the execution of the target operation if the preset conditions are not met between the first airspace range and the target airspace range.

[0221] Thus, since the terminal can cancel receiving the reference signal from the network-side device and / or cancel measuring the reference signal if it determines that the beam range of the transmission to be sent by the network-side device does not cover the beam range of the reference signal transmitted through the channel in a certain beam direction, the terminal can avoid the problem of the terminal still receiving the reference signal and performing RLM in that beam direction when the network-side device fails the Directional LBT in the beam direction of the reference signal transmission and the reference signal cannot be transmitted. In this way, the communication quality of the terminal can be improved.
