Technical Field

[0002] In a communication system, there are usually management nodes (also called scheduling nodes) and managed nodes (also called scheduled nodes). For example, in an in-vehicle wireless communication system, the managed nodes may be in the form of sensors, microphone arrays, speaker arrays, and other devices. The managed nodes can implement in-vehicle services such as active noise reduction and in-car calls, but the implementation of such services results in high power consumption of the managed nodes during the communication process, which is not conducive to energy saving and consumption reduction of the managed nodes.

[0028] Figure 1A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a terminal 11 and a network side device 12. Among them, the terminal 11 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal side devices, and the wearable device includes: a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0029] The channel monitoring method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0030] Please refer to 2. Figure 2 A channel monitoring method provided in an embodiment of the present application is applied to a first node. Figure 2 As shown, the channel monitoring method includes the following steps:

[0031] Step 201: Acquire configuration parameters, where the configuration parameters are used to instruct the first node to perform non-continuous channel monitoring.

[0032] It should be noted that the first node is a communication node in the communication system. In some implementation scenarios, the first node may also be referred to as a managed node, a scheduled node, or a terminal node. Accordingly, the communication system also includes a second node corresponding to the first node. In some implementation scenarios, the second node may also be referred to as a management node or a scheduling node. The solution provided in the embodiment of the present application may be applied in different communication systems, such as a vehicle-mounted wireless short-range communication system, an LTE system, an NR system, and the like.

[0033] For example, taking the vehicle-mounted wireless short-range communication system as an example, the first node may be called a T-node (Terminal Node, T-Node), or a scheduled node; the second node may be called a C-node (ControlNode, C-Node), or a scheduling node. The T-node may be a variety of device forms such as a sensor, a microphone array, a speaker array, etc. If there are multiple domains, such as domains related to control keys and vehicle access, such as a keyless entry and start system (Passive Entry Passive Start, PEPS), domains for controlling related devices through online applications and cloud services (such as T-BOX as the main control, Telematics BOX), domains for controlling the vehicle body (such as controlling windows, doors, lamps, etc.), and domains for controlling media-related devices (such as controlling microphones, speakers, etc.), the C-node may refer to the main central control center in the vehicle, or to the control nodes in each domain, and the T-node may refer to specific vehicle-mounted devices (such as microphones, speakers, etc.), or to the control nodes in each domain. At this time, these control nodes can be regarded as T-nodes that are uniformly connected to the vehicle central control center.

[0034] In addition, the vehicle-mounted wireless short-range communication system also includes a link for carrying data transmission from the control node (C node) to the managed node (T node) (Communication link for the data transmission from the Control Node, CT link), which can also be called a CT link, or a management node sending link, or a terminal node receiving link; and also includes a link for carrying data transmission from the managed node to the management node (Communication link for the data transmission from the Terminal Node, TC link), which can also be called a TC link, or a management node receiving link, or a terminal node sending link.

[0035] In the embodiment of the present application, there may be different implementation methods for the first node to obtain the configuration parameters.

[0036] Optionally, step 201 may include at least one of the following:

[0037] Acquire configuration parameters configured by the second node through high-layer signaling or layer 2 signaling;

[0038] Obtain configuration parameters of broadcast channels or other public channel indications;

[0039] Get the configuration parameters specified by the protocol;

[0040] When the first node is in a non-connected state, acquiring a saved configuration parameter, where the configuration parameter is configured by the second node when the first node is in a connected state;

[0041] Gets the preconfigured configuration parameters.

[0042] The above different implementation methods are described in detail below.

[0043] In a first implementation, the first node may obtain configuration parameters configured by the second node through high-level signaling or layer 2 signaling. For example, when the first node is in a connected state, the first node may be connected to other nodes through a channel and be in an activated state; for example, the first node and the second node are connected through a channel, and the second node can configure the configuration parameters to the first node through high-level signaling or layer 2 signaling. Alternatively, when the first node is in a non-connected state, the configuration parameters configured by the second node through high-level signaling or layer 2 signaling may be obtained, and the configuration parameters may be sent through broadcast information. Among them, the non-connected state may include multiple conditions such as an inactive state and an idle state.

[0044] In a second implementation, the first node obtains configuration parameters indicated by a broadcast channel or other public channels. For example, when the first node is in a non-connected state, the first node may obtain configuration parameters indicated by the second node through a broadcast channel or other public channels.

[0045] In a third implementation, the first node may obtain configuration parameters specified by the protocol. That is, the configuration parameters are specified by the protocol, such as directly writing the parameters in text in the protocol, and there is no need to configure through the second node or other communication devices.

[0046] In a fourth implementation, when the first node is in a non-connected state, a saved configuration parameter is obtained, and the configuration parameter is configured by the second node when the first node is in a connected state. For example, when the first node was previously in a connected state, the configuration parameter configured by the second node obtained when it was in a connected state is saved, that is, the first node does not release the configuration parameter after entering the non-connected state, and then after the first node enters the non-connected state, the channel can be non-continuously monitored based on the saved configuration parameter.

[0047] In a fifth implementation, the first node may obtain pre-configured configuration parameters. It should be noted that the pre-configuration in this implementation may refer to factory pre-configuration in the communication device, and different communication devices may have different pre-configurations.

[0048] In addition, the first node may also obtain configuration parameters including at least one of the above implementations, such as obtaining configuration parameters configured by the second node through high-level signaling or layer 2 signaling and based on a broadcast channel or other public channel indication. Of course, the first node may also obtain configuration parameters in other specific implementations, which are not listed one by one in the embodiments of the present application.

[0049] In an embodiment of the present application, regardless of whether the first node is in a connected state or a disconnected state, it is possible to obtain configuration parameters for instructing the first node to perform non-continuous channel monitoring based on a corresponding method, thereby enabling the first node to perform non-continuous channel monitoring based on the configuration parameters to save power consumption of the first node.

[0050] Optionally, the configuration parameters include at least one of the following:

[0051] an identifier of the first node;

[0052] an identifier of the second node;

[0053] The time domain and / or frequency domain position of the resource that the first node needs to monitor;

[0054] A resource set where resources that the first node needs to monitor are located;

[0055] A monitoring parameter used by the first node to monitor the resource;

[0056] a correspondence between the identifier of the first node and the resources that need to be monitored;

[0057] A correspondence between the index identifier of the first node and the resource to be monitored;

[0058] A correspondence between the identifier of the second node and the resources that need to be monitored;

[0059] A correspondence between the index identifier of the second node and the resource to be monitored;

[0060] The threshold value corresponding to the reference signal;

[0061] Measurement related configuration;

[0062] Multiple-input multiple-output MIMO maximum number of transmission streams configuration;

[0063] The type of control signaling that needs to be monitored;

[0064] The channel type to monitor.

[0065] The identifier of the first node or the identifier of the second node includes at least one of the following:

[0066] Layer 2 identification;

[0067] Equipment identification;

[0068] Device type identification;

[0069] Device domain identifier;

[0070] Physical layer identification;

[0071] Access ID.

[0072] It should be noted that when the method is applied to an in-vehicle wireless short-range communication system, the first node can be called a T node, and the device type identifier of the T node can be used to indicate whether the T node belongs to an entertainment device or a safety-related device; or, the device domain identifier can also be used to indicate whether the T node belongs to a T-box domain or a body control domain.

[0073] Among them, the layer 2 identifier can be a representation used for addressing when performing layer 2 communication, and is applicable to T nodes and C nodes. The device identifier can be based on each different hardware device and other associated identifiers. This identifier can be globally unique, or unique to a single vehicle-mounted wireless short-range communication system, or unique to a certain control domain, etc., and is applicable to T nodes and C nodes. The device domain identifier can also be applicable to T nodes and C nodes. The physical layer identifier is used to identify a C node or T node at the physical layer during communication, such as a radio network temporary identifier (Radio Network Temporary Identity, RNTI).

[0074] In addition, the access identifier may refer to an identifier used by the second node for access, such as a service set identifier (SSID). For example, the configuration parameter may include an identifier of the second node, and the identifier of the second node includes a device identifier and an access identifier. Based on the obtained device identifier and access identifier of the second node, the first node can know which second node manages or schedules the first node, thereby monitoring the relevant channel.

[0075] It should be noted that the resource that the first node needs to monitor may refer to a specific location that needs to be monitored, that is, a time domain location and a frequency domain location for monitoring. In an embodiment of the present application, the configuration parameters may include a specific time domain and / or frequency domain location of the resource that the first node needs to monitor, and based on the specific time domain location and / or frequency domain location, the resource location that needs to be monitored can be determined.

[0076] The resource set where the resources that the first node needs to monitor are located may refer to potential specific locations that need to be monitored, and the specific locations that actually need to be monitored may be determined by other information in the configuration parameters, such as each node based on an identifier, the correspondence between the identifier and the resources that need to be monitored, and other information.

[0077] Optionally, the monitoring parameter used by the first node to monitor the resource includes at least one of the following:

[0078] Duration of monitoring;

[0079] The duration of non-monitoring after a single monitoring session ends;

[0080] Monitoring cycle;

[0081] The starting position of monitoring;

[0082] An offset value used to indicate the start position of monitoring.

[0083] It can be understood that based on the set of resources that the first node needs to monitor, it is also possible to determine the duration of the monitoring of the channel by the first node, or the monitoring period, etc. Among them, the duration of the monitoring can be determined by a timer, or can be a fixed time, and the fixed time can be an absolute time or an integer multiple of the minimum unit of scheduling. Optionally, the resources that need to be monitored do not include system overhead resources indicated by the system overhead resource indication channel, and active noise reduction service resources indicated by the active noise reduction service resource pool indication information.

[0084] In an embodiment of the present application, the configuration parameter may also include a correspondence between the identifier of the first node and the resource to be monitored. For example, it may be a correspondence between the device identifier of the first node and the time domain position to be monitored, or a correspondence between the device type identifier of the first node and the frequency domain position to be monitored, etc.

[0085] The configuration parameters may also include a correspondence between the identifier of the second node and the resource to be monitored, for example, a correspondence between the layer 2 identifier of the second node and the position to be monitored, or a position relationship between the device identifier of the second node and the frequency domain position to be monitored, etc.

[0086] It should be noted that in the vehicle-mounted wireless short-range communication system, if there are multiple domains, it may be required to monitor a specific domain or to access a domain that has been previously accessed or configured. In addition, if the control node of each domain is used as the second node, that is, the C node, the monitoring position, monitoring period, etc. of different C nodes may also be different. For example, the resource set that needs to be monitored may be related to the C node (such as the identifier of the C node, the domain to which the C node belongs, the broadcast access ID of the C node such as the SSID, etc.), so that the monitoring positions of different domains can be staggered, thereby avoiding collision interference, and also helping the T node to access multiple domains at the same time.

[0087] In the embodiment of the present application, the configuration parameters may also include a correspondence between the index identifier of the first node and the resource to be monitored, such as a correspondence between the index identifier of the first node and the location to be monitored, etc. The index identifier of the first node may be obtained by calculating the identifier of the first node, such as performing a truncation operation, a hash operation, a mapping operation, etc. on the identifier of the first node.

[0088] The configuration parameters may also include a correspondence between the index identifier of the second node and the resource to be monitored, such as a correspondence between the index identifier of the second node and the location to be monitored, etc. The index identifier of the second node may be obtained by calculating the identifier of the second node, such as performing a truncation operation, a hash operation, a mapping operation, etc. on the identifier of the second node.

[0089] The configuration parameters may also include thresholds corresponding to reference signals, and the reference signals may include channel state information reference signals (CSI-RS), demodulation reference signals (DMRS), sounding information reference signals (SRS), etc.

[0090] The configuration parameters may also include measurement-related configurations, and the measurement-related configurations include at least one of the following: a measurement object, a measurement period, a measurement quantity, a measurement identifier, and a measurement reporting location. The measurement quantity may include at least one of a reference signal received power (RSRP) and a reference signal received quality (RSRQ).

[0091] The configuration parameters also include a multi-input multi-output (MIMO) maximum transmission stream number configuration.

[0092] The configuration parameters may also include a control signaling type that needs to be monitored. The control signaling type may be a format indicating a specific downlink control information (Downlink Control Information, DCI), or a DCI indicating a specific type of service.

[0093] The configuration parameter may further include a channel type to be monitored. Optionally, the channel type to be monitored includes at least one of the following:

[0094] Synchronous channel;

[0095] Broadcast channel;

[0096] A channel for the second node to send dynamic scheduling signaling;

[0097] A channel for the second node to send semi-persistent scheduling signaling;

[0098] Data transmission channel;

[0099] Data receiving channel.

[0100] It should be noted that the above configuration parameters are not necessarily sent in the same configuration message. For example, at the beginning of the access process, the first node obtains the identifier of the second node, and in the subsequent high-level signaling or layer 2 signaling from the second node to the first node, the first node obtains the resources that need to be monitored. For another example, at the beginning of the access process, the first node obtains the identifier configured by the second node to the first node, and in the subsequent high-level signaling or layer 2 signaling, the first node obtains the resources that need to be monitored.

[0101] Step 202: Perform non-continuous channel monitoring based on the configuration parameters.

[0102] It can be understood that after the first node obtains the configuration parameters, it can also perform non-channel monitoring based on the configuration parameters. For example, the configuration parameters include the time domain and frequency domain positions of the resources that the first node needs to monitor, the starting position of the monitoring, and the monitoring period, and then based on these configuration parameters, the first node can also perform non-continuous channel monitoring on the resources at the corresponding frequency domain position and time domain position based on the monitoring period and the starting position of the monitoring.

[0103] In an embodiment of the present application, the first node obtains configuration parameters, such as the type of channel to be monitored, the starting position of monitoring, the resource set where the resources to be monitored are located, etc., and then the first node can perform non-continuous monitoring of the channel based on the configuration parameters, so that the first node can perform subsequent transmission or access operations according to the monitored information, thereby reducing the power consumption of the first node.

[0104] Optionally, step 202 may include:

[0105] Based on the configuration parameters, reference signal measurement is performed on the channel to be monitored at the corresponding resource set.

[0106] As described above, the reference signal may include CSI-RS, DMRS, SRS, etc. After acquiring the configuration parameters, the first node can determine the corresponding resource set based on the configuration parameters, and then perform reference signal measurement on the channel to be monitored at the corresponding resource set.

[0107] It should be noted that the corresponding resource set may be determined by at least one of the following:

[0108] Preconfigured configuration parameters;

[0109] an identifier of the first node;

[0110] An index identifier of the first node;

[0111] a correspondence between the identifier of the first node and the resources that need to be monitored;

[0112] A correspondence between the index identifier of the first node and the resource to be monitored;

[0113] an identifier of the second node;

[0114] A correspondence between the identifier of the second node and the resources that need to be monitored;

[0115] The corresponding relationship between the index identifier of the second node and the resources that need to be monitored.

[0116] Optionally, when the RSRP and / or RSRQ of the parameter signal is greater than or equal to the corresponding access threshold, the method further includes:

[0117] Sending measurement reporting information to the second node; or,

[0118] Access information is sent on the access channel.

[0119] That is to say, when the first node performs reference signal measurement on the channel to be monitored at the corresponding resource set based on the configuration parameters, if the RSRP of the reference signal is greater than or equal to the corresponding access threshold, and / or the RSRQ of the reference signal is greater than or equal to the corresponding access threshold, the first node sends measurement reporting information to the second node, and the measurement reporting information is used to indicate that when the first node performs reference signal measurement on the monitored channel, the RSRP and / or RSRQ of the reference signal is greater than or equal to the corresponding access threshold.

[0120] Alternatively, the first node may also send access information on an access channel, where the access information is used to indicate that when the first node measures the reference signal on the monitored channel, the RSRP and / or RSRQ of the reference signal is greater than or equal to a corresponding access threshold.

[0121] In the embodiment of the present application, the first node performs non-continuous monitoring of the channel based on the acquired configuration parameters. When the first node monitors the preset signaling, the method may further include:

[0122] Perform a preset operation based on the indication information in the preset signaling.

[0123] That is, the first node can perform relevant operations according to the monitored information. The preset signaling includes at least one of the following:

[0124] signaling including an identification of the first node;

[0125] A signaling including an index identifier of the first node;

[0126] The signaling is scrambled by the identifier of the first node or the index identifier of the first node.

[0127] signaling including an identification of the second node;

[0128] A signaling including an index identifier of the second node;

[0129] The signaling is scrambled by the identifier of the second node or the index identifier of the second node.

[0130] For example, if the preset signaling includes the identifier of the first node or is encrypted with the identifier of the first node, the preset signaling is indicated to the first node, and then the first node performs a preset operation based on the preset information.

[0131] It should be noted that in some implementation scenarios, the preset signaling may only include the identifier of the second node. In this case, all first nodes connected to the second node can regard the preset signaling as an instruction to themselves, that is, it does not distinguish which first node the preset signaling is sent to, but is sent to all first nodes connected to the second node.

[0132] In addition, in some implementation scenarios of multiple control domains, the preset signaling sent by the centrally controlled second node may include the identifier of the control node in each control domain (at this time, the control node can be regarded as the second node compared to the first node in each control domain). At this time, if the identifier received by the first node is the identifier of the control node of the domain to which it has access, it is also considered that the identifier is used to indicate that the preset signaling is for itself.

[0133] Optionally, the preset operation includes at least one of the following:

[0134] Data reception;

[0135] Data transmission;

[0136] State switching, wherein the state switching is switching from a connected state to a disconnected state or from a disconnected state to a connected state;

[0137] Activate the configured sending resources;

[0138] Activates a configured receive resource.

[0139] In an embodiment of the present application, the first node performs a preset operation based on the indication information in the preset signaling. For example, if the preset signaling includes the identifier of the first node, the first node may perform preset operations such as data transmission, data reception, and state switching on the corresponding channel. For another example, if the preset signaling includes the identifier of the second node, the first nodes connected to the second node are determined based on the identifier of the second node, and then the first node connected to the second node may perform preset operations such as data transmission and data reception on the corresponding channel.

[0140] In the embodiment of the present application, when the first node receives the preset signaling, the first node may perform subsequent preset operations when the preset signaling meets the control signaling type that needs to be monitored configured in the configuration parameters.

[0141] It should be noted that the first node may include a connected state and a non-connected state, and the non-connected state may include multiple possibilities such as an idle state and an inactive state. Different states may include the following differences.

[0142] Different states can be defined from the perspective of data transmission, such as the frequency of transmission: the connected state requires continuous data transmission, while the unconnected state does not. Specifically, the connected state may monitor the C link continuously or periodically based on the configuration or broadcast channel indication. The same cycle includes the awake state and the dormant (sleep) state. The awake state monitors, and the dormant state does not monitor. The connected state can send data at any time; the unconnected state may monitor the C link occasionally (periodically or non-periodically) based on the configuration or broadcast channel indication. When hearing information related to itself, it needs to access or restore the link, and then send or receive subsequent data. To send data in the unconnected state, it may also need to access or restore the link.

[0143] Different states are defined based on their security mechanisms and security levels: the connected state is security activated, and the unconnected state is unsecurity activated.

[0144] Different states are defined based on whether the context of the terminal needs to be stored in different states: in the connected state, the second node has the context of the first node, and in the unconnected state, there is no context.

[0145] Different states are defined based on whether different signaling configurations are required in different states: the connection state requires the first node and the second node to perform signaling configuration interaction, while the non-connection state does not require (or does not require too much) signaling configuration interaction.

[0146] Different states are distinguished based on the behavior of the first node: for example, the connected state is that the second node schedules the first node to send and receive data, and the unconnected state is that the first node needs to access first after receiving the signaling, and then send and receive subsequent data.

[0147] Specifically, for the inactive state and the idle state, the inactive state may have the same characteristics as the connected state in some cases, such as, the inactive state may be securely activated, or the inactive state is that the second node has the context of the first node, or the inactive state needs to access first after receiving the signaling, and the access at this time is a fast connection recovery, etc. This embodiment will not go into details.

[0148] It should be noted that the switching of the first node from the non-connected state to the connected state may be achieved by sending an access message on an access channel.

[0149] Optionally, when the first node monitors preset signaling on the first channel, performing a preset operation based on indication information in the preset signaling includes:

[0150] Perform a preset operation on the second channel based on the indication information in the preset signaling.

[0151] That is, after the preset signaling is heard on channel A, subsequent preset operations may be performed on channel B. For example, if the preset signaling is heard on a channel used for dynamic scheduling signaling, sending or receiving may be performed on a data sending or data receiving channel; for another example, if the preset signaling is heard on a channel used for dynamic scheduling signaling, access information may be sent on an access channel.

[0152] In order to better understand the technical solutions provided by the embodiments of the present application, several different implementation methods will be described in detail below.

[0153] In the first implementation, if the first node is in a connected state, the signaling sent to the first node is determined by the identifier of the first node, and subsequent preset operations are performed according to the signaling instructions. The specific implementation steps are as follows:

[0154] Step 11: The second node informs the first node of configuration parameters through high-layer signaling or layer 2 signaling configuration, or broadcast channel indication, and the configuration parameters may include an identifier of the first node;

[0155] Step 12: The first node performs non-continuous channel monitoring on a channel used for dynamic scheduling signaling (e.g., a C-link dynamic scheduling signaling channel) based on the configuration parameters, wherein the configuration parameters include monitoring parameters. Within a monitoring cycle, the first node can be divided into an awake state and a dormant state. In the awake state, the first node monitors the C-link dynamic scheduling signaling channel or other channels according to the configured monitoring duration, and enters the dormant state after the monitoring duration. In the dormant state, the first node does not monitor the C-link dynamic scheduling signaling channel;

[0156] Step 13: Further, the first node receives a preset signaling when monitoring the C link dynamic scheduling signaling channel, where the preset signaling is scrambled by the physical layer identifier of the first node, or the signaling includes other identifiers of the first node;

[0157] Step 14: Based on the indication of the preset signaling, the first node performs a preset operation, such as sending and receiving subsequent services, at the resource location and / or channel indicated by the preset signaling.

[0158] In the second implementation, if the first node is in a non-connected state, the signaling sent to the first node is determined by the identifier of the first node, and access is performed. The specific implementation steps are as follows:

[0159] Step 21: The second node informs the first node of configuration parameters and / or an identifier of the first node through high-layer signaling or layer 2 signaling configuration, or broadcast channel indication;

[0160] Step 22: The first node obtains a resource set where the resources to be monitored are located based on the configuration parameters of the second node; this resource set is common to all first nodes, that is, all resources to be monitored by the first nodes are in this resource set; and according to the corresponding relationship between the identifier of the first node and the resources to be monitored agreed upon in the protocol, such as a formula based on the identifier of the first node as input, a specific resource location is calculated, and the C link dynamic scheduling signaling channel or other channels are monitored at the specific resource;

[0161] Step 23: The first node receives a preset signaling, where the preset signaling is scrambled by the physical layer identifier of the first node, or the preset signaling includes other identifiers of the first node;

[0162] Step 24: The first node sends an access message on an access channel based on the preset signaling;

[0163] Step 25: The first node successfully accesses the second node, and the configuration parameters previously configured by the second node through high-level signaling or layer 2 signaling, or indicated by the broadcast channel and sent to the first node are no longer effective, and the first node begins to continuously monitor the C-link dynamic scheduling signaling channel; alternatively, the second node may configure or indicate new configuration parameters to the first node through high-level signaling or layer 2 signaling, or through the broadcast channel, and the first node monitors based on the new configuration parameters.

[0164] It should be noted that, in step 24, if the first node further defines an idle state and an inactive state, an access message may be sent for the idle state, and a link fast recovery message may be sent for the inactive state. Of course, in some implementation scenarios, the inactive state may also be other names, mainly referring to the link connection between the first node and the second node being between the idle state and the inactive state.

[0165] In a third implementation, if the first node does not define a connected state or a non-connected state, the first node may perform non-continuous channel monitoring based on a pre-configured or broadcast channel indication. The specific implementation steps are as follows:

[0166] Step 31: The second node informs the first node of configuration parameters and / or an identifier of the first node through high-layer signaling or layer 2 signaling configuration, or broadcast channel indication;

[0167] Step 32: The first node obtains the resource set where the resource to be monitored is located and the corresponding monitoring parameters based on the configuration parameters of the second node; and according to the corresponding relationship between the identifier or index identifier of the first node and the resource to be monitored agreed upon in the protocol, such as the result calculated by a formula based on the identifier of the first node as input, or the first node identifier is truncated, hashed or directly mapped and then corresponds to a specific resource location; optionally, in combination with other indication information in the monitoring parameters, the specific resource location is obtained, and during the awake state specified by the monitoring parameters, the C link dynamic scheduling signaling channel or other channels are monitored at the specific resource location; the specific resource location may also be directly indicated by the second node;

[0168] Step 33: The first node receives a preset signaling, where the preset signaling is scrambled by the physical layer identifier of the first node, or the preset signaling includes other identifiers of the first node;

[0169] Step 34: The first node performs a preset operation at the resource location and / or channel indicated by the signaling based on the indication information of the preset signaling, such as sending and receiving subsequent services (or the preset signaling does not indicate a specific channel, and after the first node receives the preset signaling, it defaults to the preset channel for subsequent actions, such as monitoring the C-link dynamic scheduling signaling channel, or receiving data on the data receiving channel); or, the first node can also activate the configured sending resources and / or activate the configured receiving resources based on the preset signaling; the sending resources and receiving resources can be used to send or receive active noise reduction services, or other types of services.

[0170] In the fourth implementation, the implementation scenario is the first node access when multiple control domains coexist, including the following specific implementation steps:

[0171] Step 41: The second node (A) notifies the first node of configuration parameters through high-layer signaling or layer 2 signaling configuration, or broadcast channel indication;

[0172] Step 42: The first node (B) determines the corresponding resource to be monitored based on the identifier of the control node in the control domain to which it accesses (in this case, the control node is the second node compared to B, and the control node is the first node compared to A; or the control node is the second node compared to B, and the control node is another second node compared to A) according to the corresponding relationship between the identifier and the resource set, and monitors the channel at the specific resource; the channel to be monitored in this case may be: at least one of the synchronization channel, the broadcast channel, the C-link dynamic scheduling signaling channel, and other newly defined scheduling channels;

[0173] Step 43: The first node receives a preset signaling, where the preset signaling is scrambled by the physical layer identifier of the first node, or the preset signaling includes other identifiers of the first node;

[0174] Step 44: The first node performs a preset operation at the resource location and / or channel indicated by the signaling based on the indication information of the preset signaling, such as sending and receiving subsequent services (or the preset signaling does not indicate a specific channel, and after the first node receives the preset signaling, it defaults to the preset channel for subsequent actions, such as monitoring the C-link dynamic scheduling signaling channel, or receiving data on the data receiving channel); or, the first node can also activate the configured sending resources and / or activate the configured receiving resources based on the preset signaling; the sending resources and receiving resources can be used to send or receive active noise reduction services, or other types of services.

[0175] In the fifth implementation, if the first node defines a connected state and a non-connected state, the first node in the non-connected state performs non-continuous monitoring of the channel based on the configuration in the connected state. The specific implementation steps are as follows:

[0176] Step 51: The second node sends configuration parameters to the first node for non-continuous channel monitoring; the configuration parameters include a first configuration parameter and a second configuration parameter, the first configuration parameter is used for non-continuous channel monitoring in a connected state, and the second configuration parameter is used for non-continuous channel monitoring in a non-connected state;

[0177] Step 52: The first node performs non-continuous monitoring of the channel in the connected state according to the first configuration parameter used in the connected state;

[0178] Step 53: The second node sends a preset signaling to instruct the first node to perform a state transition, and the first node changes from a connected state to a non-connected state;

[0179] Step 54: the first node enters a non-connected state according to a preset signaling, and at this time performs non-continuous monitoring of the channel based on the second configuration parameter for the non-connected state previously sent by the second node.

[0180] In an embodiment of the present application, the first node performs non-continuous monitoring of the relevant channel by acquiring configuration parameters, and can perform preset operations such as data transmission and reception based on the received preset signaling, thereby reducing the power consumption of the first node.

[0181] It should be noted that in the embodiment of the present application, if the first node defines a connected state or a non-connected state, the solution provided in the embodiment of the present application implements specific steps (such as the above-mentioned implementation methods 1 and 2) based on the corresponding state (connected state or non-connected state), and if the first node does not distinguish between a connected state and a non-connected state, the solution provided in the embodiment of the present application can implement specific steps (such as the above-mentioned implementation methods 3 and 4) regardless of the state. Of course, the specific implementation methods of the embodiment of the present application are not limited to the five described above, and they are not listed one by one here.

[0182] Please refer to 3. Figure 3 is another channel monitoring method provided in an embodiment of the present application, and the channel monitoring method is applied to the second node. Figure 3 As shown, the channel monitoring method includes the following steps:

[0183] Step 301: Send configuration parameters to a first node, where the configuration parameters are used to instruct the first node to perform non-continuous channel monitoring.

[0184] It should be noted that the second node in the embodiment of the present application is a communication node corresponding to the first node in the communication system. For example, in some implementation scenarios, the second node may also be referred to as a management node, or a scheduling node; the first node may also be referred to as a managed node, or a scheduled node, or a terminal node. For example, taking the vehicle-mounted wireless short-range communication system as an example, the first node may be referred to as a T-node (Terminal Node, T-Node), or a scheduled node; the second node may be referred to as a C-node (Control Node, C-Node), or a scheduling node. For details, please refer to the above Figure 2 The specific description in the embodiments is not repeated in this embodiment.

[0185] In the embodiment of the present application, step 301 may include:

[0186] An assistance message sent by a first node is received, and configuration parameters are sent to the first node based on the assistance message.

[0187] That is, before the second node sends configuration parameters to the first node, the first node sends an auxiliary message to the second node, and then the second node sends configuration parameters for non-continuous channel monitoring to the first node based on the auxiliary message.

[0188] Optionally, the assistance message includes at least one of the following:

[0189] an identifier of the first node;

[0190] An index identifier of the first node;

[0191] measurement-related configuration required by the first node;

[0192] a reference signal threshold required by the first node;

[0193] configuration parameters required by the first node;

[0194] The maximum number of multiple-input multiple-output MIMO transmission streams configuration required by the first node.

[0195] For example, the auxiliary message includes the identifier of the first node and / or the index identifier of the first node, and then the second node can determine to which first node the configuration parameters are sent based on the identifier of the first node and / or the index identifier of the first node.

[0196] Alternatively, the auxiliary message includes the required measurement-related configuration, or in some expressions, it may also be referred to as a preferred measurement-related configuration. The measurement-related configuration may include at least one of a measurement object, a measurement period, a measurement quantity, a measurement identifier, and a measurement reporting configuration. The second node sends configuration parameters to the first node based on the required measurement-related configuration, and the configuration parameters correspondingly include measurement-related configurations, such as a measurement object, a measurement period, a measurement quantity, and the like.

[0197] It can be understood that the auxiliary message may also include the reference signal threshold that the node prefers or requires, the configuration parameters that the first node prefers or requires, the MIMO maximum transmission stream number configuration that the first node prefers or requires, etc., then the second node can configure the configuration parameters accordingly based on the specific content of the auxiliary message, which are not listed one by one in this embodiment.

[0198] Optionally, step 301 may further include:

[0199] The configuration parameters are sent to the first node based on high-layer signaling or layer 2 signaling.

[0200] That is to say, the second node may send the configuration parameters to the first node based on high-level signaling or layer 2 signaling. For example, when the first node is in a connected state, there is a channel connection between the first node and the second node, and then the second node can configure the configuration parameters to the first node through high-level signaling or layer 2 signaling. Alternatively, when the first node is in a non-connected state, it is also possible to obtain the configuration parameters configured by the second node through high-level signaling or layer 2 signaling, and the configuration parameters may be sent by the second node through broadcast information. Among them, the non-connected state may include various conditions such as inactive state and idle state.
