[0055] As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0059] 1. LTE D2D / V2X

[0060] Device-to-device communication is a sidelink (SL) transmission technology based on D2D. Unlike traditional cellular systems, where communication data is received or sent via base stations, the IoV system uses direct end-to-end communication, resulting in higher spectrum efficiency and lower transmission latency. As shown in Figures 1A and 1B, the 3rd Generation Partnership Project (3GPP) provides two transmission modes: Mode A and Mode B.

[0061] Mode A: The terminal's transmission resources are allocated by the base station, and the terminal sends data on the sidelink based on the resources allocated by the base station. The base station can allocate resources for a single transmission or for semi-static transmission.

[0062] Mode B: The vehicle terminal selects a resource in the resource pool for data transmission.

[0063] In 3GPP, D2D is divided into different phases for research.

[0064] (1) Proximity-based Service (ProSe): In Rel-12 / 13, device-to-device communication was studied for ProSe scenarios, mainly targeting public safety services.

[0065] In ProSe, by configuring the position of the resource pool in the time domain, for example, the resource pool is non-continuous in the time domain, the UE can transmit / receive data discontinuously on the sidelink, thereby achieving power saving.

[0066] (2) Vehicle-to-everything (V2X): In Rel-14 / 15, the vehicle-to-everything (V2X) system was studied for vehicle-to-vehicle communication scenarios, mainly targeting relatively high-speed vehicle-to-vehicle and vehicle-to-pedestrian communication services.

[0067] In V2X, since the on-board system has continuous power supply, power efficiency is not the main issue, but the delay of data transmission is the main issue. Therefore, the system design requires the terminal equipment to perform continuous transmission and reception.

[0068] (3) Wearable devices, i.e., Further Enhancements to LTE Device to Device (FeD2D): In Rel-14, this scenario studies the scenario of wearable devices accessing the network through mobile phones, mainly targeting scenarios with low mobile speed and low power access.

[0069] In FeD2D, 3GPP concluded during its pre-research phase that a base station could configure the remote terminal's discontinuous reception (DRX) parameters through a relay terminal. However, because this topic has not yet entered the standardization phase, the specific details of how DRX is configured remain unresolved.

[0070] (4) Multi-carrier: In Rel-15LTE V2X, a multi-carrier mechanism is introduced. Specifically, the multi-carrier mechanism is reflected in the UE's ability to support: packet segmentation, transmitting data packets using multiple carriers to improve data transmission rate; packet replication, copying the same data packet twice and sending it using two carriers to improve transmission reliability; and multi-carrier reception enhancement at the receiving end. Specifically, for packet replication: V2X sidelink communication supports sidelink packet replication and is executed at the Packet Data Convergence Protocol (PDCP) layer of the UE. For sidelink packet replication for transmission, the PDCP protocol data unit (PDU) is replicated at the PDCP entity. The replicated Packet Data Protocol (PDP) PDU of the same PDCP entity is submitted to two different Radio Link Control (RLC) entities and associated with two different sidelink logical channels respectively. The replicated PDP PDU of the same PDCP entity is only allowed to be transmitted on different sidelink carriers. The UE can activate or deactivate sidelink packet replication based on (pre) configuration. Sidelink packet replication is not applicable for transmissions with the Rel-14 transmission profile. The ProSe Per-Packet Reliability (PPPR) value for supporting sidelink packet replication may be (pre-)configured via a PPPR threshold. For UE autonomous resource selection and scheduled resource allocation, the UE shall perform sidelink packet replication for data with configured PPPR values ​​until packet replication is unconfigured for these PPPR values. For scheduled resource allocation, the UE reports the amount of data associated with one or more PPPR values ​​and the destination to which the data belongs via a sidelink Buffer Status Report (BSR). The mapping of PPPR values ​​to logical channel groups may be configured by the eNB and the PPPR value reflected by the associated logical channel group identifier (ID) included in the sidelink BSR. A list of one or more PPPR values ​​may be reported by a Radio Resource Control (RRC) connected UE in the sidelink UE information.

[0071] 2.NR V2X

[0072] Based on LTE V2X, NR V2X is not limited to broadcast scenarios, but has been further expanded to unicast and multicast scenarios, and the application of V2X is studied in these scenarios.

[0073] Similar to LTE V2X, NR V2X will also define two resource authorization modes, Mode-1 / 2, which are similar to Mode A and Mode B mentioned above. Furthermore, the user may be in a mixed mode, that is, they can use both Mode-1 and Mode-2 to acquire resources. The resource acquisition is indicated by the sidelink grant, that is, the sidelink grant indicates the time-frequency position of the corresponding physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH) resources.

[0074] Unlike LTE V2X, in addition to the feedback-free, UE-initiated Hybrid Automatic Repeat reQuest (HARQ) retransmission, NR V2X introduces feedback-based HARQ retransmission, which is not limited to unicast communication but also includes multicast communication.

[0075] Similar to LTE V2X, in NR V2X, power efficiency is not a major issue because the on-board system has continuous power supply, but data transmission latency is the main issue. Therefore, the system design requires terminal devices to perform continuous transmission and reception.

[0076] The sidelink terminal triggers the sidelink RRC reconfiguration procedure in the following scenarios:

[0077] Release sidelink data bearer in unicast communication;

[0078] Establishing a sidelink data bearer in unicast communication;

[0079] Modify the relevant configuration of the sidelink data bearer in unicast communication;

[0080] In the terminal-to-network relay scenario, the direct communication interface (Proximity Communication 5, PC5) relay RLC channel between the Layer 2 relay terminal and the remote terminal (or remote terminal) is released;

[0081] In the terminal-to-network relay scenario, a PC5 relay RLC channel is established between the Layer 2 relay terminal and the remote terminal;

[0082] In a terminal-to-network relay scenario, modify the configuration parameters related to the PC5 relay RLC channel between the Layer 2 relay terminal and the remote terminal;

[0083] Reconfiguration of NR sidelink measurement reporting related parameters;

[0084] Reconfiguration of sidelink channel state information (CSI) reference signal resources and CSI reporting delay bounds;

[0085] Reconfigure the DRX of the line link on the opposite terminal side.

[0086] 3. Terminal to network relay

[0087] The remote terminal performs measurement reporting and includes information such as the relay terminal identifier, serving cell identifier, and RSRP measurement in the measurement reporting information. When the remote terminal performs a link switch from a non-direct path to a direct path, it is recommended for the serving relay terminal to use SL-RSRP for sidelink measurements. When the remote terminal performs a link switch from a direct path to a non-direct path, Sidelink Discovery (SD)-RSRP is used to perform sidelink measurements. In addition, when performing measurement reporting, two new measurement reporting triggering events are defined for terminal-to-network relay switching. Event 1 When the link quality of the serving relay terminal is lower than the configured threshold value, and, optionally, the link quality of the adjacent cell is higher than the configured threshold value, the remote terminal performs measurement reporting. Event 2 When the link quality of the serving cell is lower than the configured threshold value, and the optional relay terminal link quality is higher than the configured threshold value, the remote terminal performs measurement reporting. In addition, to assist the remote terminal in performing a direct-to-indirect link handover, a new timer is introduced. When the remote terminal receives an RRC reconfiguration message indicating a direct-to-indirect link handover, the remote terminal starts the timer. When the timer expires, the remote terminal performs an RRC re-establishment.

[0088] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0089] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0090] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0105] In one embodiment, the auxiliary information includes at least one of the following service information: estimated size of a data packet; service transmission period. For example, the service information may also be referred to as a traffic pattern.

For example, if each transmission round includes one initial transmission and two retransmissions, then three transmissions constitute one round.

[0112] In some examples, the first time domain period may be a long period, and the second time domain period may be a short period. For example, the short period is 1 ms-99 ms, and the long period is 100 ms, 200 ms, 300 ms, ..., 1000 ms.

[0148] In the embodiment of the present application, a relay node configures a resource pool for a terminal, thereby reducing signaling interaction between the terminal and the communication network.

[0149] FIG6 is a schematic flow chart of a sideline communication method 600 according to an embodiment of the present application. The method may optionally be applied to the system shown in FIG1A and / or FIG1B , but is not limited thereto. The method includes at least part of the following contents.

[0150] S610: A first terminal receives first information in which a first relay node assists the first terminal in performing a measurement function.

[0151] The first terminal accesses a first network, and the first network includes the first relay node.

[0152] In an embodiment of the present application, after a first relay node assists a first terminal in performing a measurement function, the first relay node may send first information to the first terminal. The first information includes measurement results corresponding to various measurement functions. For example, a measurement of the relay node corresponds to a first measurement result, and a measurement of the resource pool corresponds to a second measurement result.

[0153] In one embodiment, the measurement function includes measuring a second relay node, where the second relay node is a relay node that is selectable or detectable by the first terminal. In an embodiment of the present application, the second relay node can be a relay node in the first network or a relay node in a network other than the first network.

[0154] In one embodiment, the measurement of the second relay nodes includes: the first relay node using an artificial intelligence algorithm to measure one or more second relay nodes around the first terminal. For example, the first relay node may measure selectable or detectable relay nodes within a certain area and / or distance range around the first terminal. The first relay terminal may first limit the area and / or distance range before measuring, or may first measure and then filter based on the area and / or distance range.

[0155] In one implementation, the first information includes a first measurement result, where the first measurement result includes relevant information of the second relay node obtained by the first relay node through measurement.

[0156] In one embodiment, the relevant information of the second relay node includes at least one of the following:

[0157] The permanent group member identifier of the second relay node;

[0158] The measured absolute value of the second relay node;

[0159] The timestamp of the measurement execution behavior of the first relay node.

[0160] In one embodiment, as shown in FIG7 , based on the above method, the method 700 further includes: S710, the first terminal receives first control information sent by the first relay node, and the first control information is used to control the first terminal to enable measurement of the second relay node. In an embodiment of the present application, the measurement result obtained by the first terminal from measuring the second relay node can be used to compare with the measurement result obtained by the first relay terminal from measuring the second relay node. The comparison process can be performed on the first terminal or on the first relay node. If the comparison is performed on the first terminal, the comparison result can be sent to the first relay node as described below. If the comparison is performed on the first relay node, the comparison result does not need to be sent.

[0161] In one embodiment, the first control information includes third configuration information, where the third configuration information is used to configure periodic measurement of the first terminal, where the periodic measurement includes periodically performing measurement on the second relay node.

[0162] In one embodiment, the third configuration information includes at least one of the following:

[0163] Measure the first cycle;

[0164] Measure the second cycle;

[0165] the number of measurements in the first cycle and / or the second cycle;

[0166] The measurement start offset value in the first cycle and / or the second cycle.

[0167] For example, the first cycle is a long cycle and the second cycle is a short cycle. The number of measurements within a cycle may indicate the number of times the first terminal performs measurements on the second relay node within the cycle. The intra-cycle measurement start offset may indicate the position at which measurements on the second relay node are started within a cycle.

[0168] In one implementation, the third configuration information is carried via radio resource control signaling or MAC CE.

[0169] In one implementation, the first control information includes a first indication, where the first indication is used to indicate whether the first terminal needs to measure the second relay node.

[0170] In one implementation, the first indication is a relay enable indication, and the relay enable indication is used to instruct the first terminal to measure the second relay node, or to instruct the first terminal to activate measurement of the second relay node.

[0171] In one implementation, the first indication is a relay disabling indication, which is used to instruct the first terminal not to measure the second relay node, or to instruct the first terminal to deactivate measurement of the second relay node.

[0172] In one embodiment, the first indication is carried via MAC CE or physical layer signaling.

[0173] In the embodiments of the present application, the control information for periodic enabling and the control information including the first indication may be the same signaling or two different signalings. If the control information for periodic enabling contains more content, it can be carried using RRC signaling or MAC CE. If the first indication only requires a small number of bits, such as 1 bit, and needs to be more dynamic, it can be carried using MAC CE or physical layer signaling.

[0174] In one embodiment, as shown in FIG7 , the method further includes: S720 , the first terminal sends a first comparison result to the first relay node, where the first comparison result includes a relay measurement result obtained by the first terminal comparing its own measurement result with the first measurement result.

[0175] In one embodiment, the first comparison result includes: an offset value of measurement quantities of the first relay node and the first terminal for the second relay node. The measurement quantity of the first terminal for the second relay node is the measurement quantity of the first terminal for the second relay node at a time closest to the time indicated by the timestamp of the measurement quantity of the first relay node; and the offset value of the measurement quantity exceeds an offset threshold configured by the first relay node for the first terminal.

[0176] For example, the timestamp indicating time T1 indicates the measurement value M1 of the first relay node for the second relay node. The measurement value M2 of the first terminal for the second relay node at time T2, which is closest to the timestamp indicating time T1, is calculated based on the difference between M1 and M2, or the absolute value of the difference. If the offset value exceeds the offset threshold configured on the first terminal, it may indicate that the first terminal needs to provide feedback of the first comparison result to the second relay terminal. If the offset value does not exceed the offset threshold, the first terminal may not provide feedback of the first comparison result.

[0177] In one embodiment, the measurement function includes: measuring the resource pool. For example, the measurement of the resource pool may include sensing measurement of the resource pool and / or measurement of the busyness (Channel Busy Ratio, CBR, also known as channel occupancy ratio) of the resource pool.

[0178] In one embodiment, the measurement of the resource pool includes: the first relay node uses an artificial intelligence algorithm to perform perception measurement and / or CBR measurement on the resource pool configured for the first terminal.

[0179] In one embodiment, the first information includes a second measurement result, and the second measurement result includes the available resource set information and / or the resource pool CBR of the first terminal obtained by measurement by the first relay node.

[0180] In one embodiment, the available resource set information of the first terminal measured by the first relay node includes time domain information and / or frequency domain information of the available resources; wherein the time domain information includes the time domain location of the available resources, and the frequency domain information includes the frequency domain range of the available resources. For example, the time domain location of the available resources included in the time domain information may be expressed in units of time slots, subframes, milliseconds, symbols, etc. The frequency domain range of the available resources included in the frequency domain information may be expressed in units of subchannels, carriers, bandwidths, radio resource block sets, etc.

[0181] In one embodiment, as shown in FIG7 , the method further includes: S730 , the first terminal receives second control information sent by the first relay node, where the second control information is used to control the first terminal to enable measurement of the resource pool.

[0182] In one embodiment, the second control information includes fourth configuration information, where the fourth configuration information is used to configure periodic measurement of the first terminal, where the periodic measurement includes periodically performing measurement of the resource pool.

[0183] In one embodiment, the fourth configuration information includes at least one of the following:

[0184] Measure the third cycle;

[0185] Measure the fourth cycle;

[0186] Number of measurements in the third and / or fourth cycles;

[0187] The measurement start offset value is / are measured in the third cycle and / or the fourth cycle.

[0188] For example, the third cycle may be a long cycle, and the fourth cycle may be a short cycle. The number of measurements within a cycle may indicate the number of times the first terminal performs measurements on the resource pool within the cycle. The measurement start offset within a cycle may indicate the position at which measurements on the resource pool are started within a cycle.

[0189] In one implementation, the fourth configuration information is carried via radio resource control signaling or a medium access control element (MAC CE).

[0190] In one embodiment, the second control information includes a second indication, where the second indication is used to indicate whether the first terminal needs to measure the resource pool.

[0191] In one embodiment, in a scenario where perception measurement is performed on a resource pool, the second indication includes a perception enable indication, which is used to activate the perception measurement function of the first terminal for the resource pool; or, the second indication includes a perception disable indication, which is used to deactivate the perception measurement function of the first terminal for the resource pool.

[0192] In one embodiment, in the scenario of perceptual measurement of a resource pool, the method further includes:

[0193] The first terminal sends a second comparison result to the first relay node, where the second comparison result includes a perception measurement result of the first terminal comparing the available resources perceived by the first terminal with the available resources reported by the first relay node. If the first terminal first sends the available resources perceived by the first terminal to the first relay terminal, the available resources perceived by the first terminal can be directly compared with the available resources perceived by the first relay terminal at the first relay terminal, resulting in a comparison result similar to the second comparison result.

[0194] In one embodiment, the reporting condition of the second comparison result includes: the resource error number is greater than a resource error number threshold configured by the first relay node for the first terminal. If the resource error number is greater than the resource error number threshold, the first terminal sends the second comparison result to the first relay node.

[0195] In one embodiment, the second comparison result includes the mismatched resource index and / or the resource error number. For example, if the available resource indexes perceived by the first terminal include R11, R12, and R13, and the available resource indexes perceived by the first relay terminal include R12, R13, and R14, then the mismatched resource indexes include R11 and R14.

[0196] In one embodiment, the resource error number is obtained based on the current resource error, the number of resources in the available resource set of the first terminal measured by the first relay node, and the number of resources in the available resource set perceived by the first terminal. For example, the resource error number = the current resource error + |the number of resources in the available resource set of the first terminal - the number of resources in the available resource set perceived by the first terminal|.

[0197] In one embodiment, the method further includes: for all resources in the available resource set reported by the first relay node, the first terminal obtains the current resource error by taking the following steps:

[0198] If the resource index reported by the first relay node is found in the set of available resources perceived by the first terminal itself, skipping the resource index;

[0199] If the resource index reported by the first relay node cannot be found in the set of available resources perceived by the first terminal itself, the current resource error is increased by 1;

[0200] After traversing the available resource set reported by the first relay node, the current resource error is obtained.

[0201] For example, the first terminal's available resources include three resources indexed as R21, R22, and R23, and the first relay terminal's available resources include three resources indexed as R22, R23, R24, and R25. Traversing the first relay node's available resource set, since R24 and R25 are not in the first terminal's available resource indexes, the current resource error is 2. Resource error number = 2 + |5 - 3| = 4.

[0202] In one embodiment, in a scenario where CBR measurement is performed on a resource pool, the second indication includes a CBR enable indication, which is used to activate the CBR measurement function of the first terminal for the resource pool; or, the second indication includes a CBR disable indication, which is used to deactivate the CBR measurement function of the first terminal for the resource pool.

[0203] In one embodiment, the second indication is carried via MAC CE or physical layer signaling.

[0204] In one embodiment, in a scenario of measuring the CBR of a resource pool, the method further includes:

[0205] The first terminal sends a third comparison result to the first relay node, where the third comparison result includes a CBR measurement result obtained by comparing the resource pool CBR measured by the first terminal with the resource pool CBR reported by the first relay node. If the first terminal first sends the resource pool CBR measured by the first terminal to the first relay terminal, the resource pool CBR measured by the first terminal can be directly compared with the resource pool CBR measured by the first relay terminal at the first relay terminal, resulting in a comparison result similar to the third comparison result.

[0206] In one embodiment, the reporting condition of the third comparison result includes: the absolute value of the resource pool CBR error is greater than a configured resource pool CBR error threshold.

[0207] In one embodiment, the resource pool CBR error is obtained based on the resource pool CBR measured by the first relay node and the resource pool CBR measured by the first terminal. For example, resource pool CBR error = |resource pool CBR measured by the first relay node - resource pool CBR measured by the first terminal|.

[0208] In the embodiment of the present application, the relay node assists the terminal in performing measurements, which can reduce the resource overhead caused by control plane measurements and signaling interactions.

[0261] In the embodiment of the present application, the relay node assists the terminal in performing measurements, which can reduce the resource overhead caused by control plane measurements and signaling interactions.

[0263] Example 1: Master relay node A configures a resource pool for a user terminal

[0264] Step 1: After a user terminal successfully accesses a mesh network and establishes a unicast connection with a peer user terminal, when the user terminal's upper layer generates service data, the user terminal can report the service quality of service (QoS) to the primary relay node A.

[0279] Step 2: In one example, if the user terminal is configured with a resource selection method based on specific time-frequency domain rules, the user terminal needs to report user auxiliary information including a service pattern to the primary relay node A. Specifically, the service pattern may include at least one of the following information:

[0280] Estimated packet size;

[0282] Step 3: The primary relay node A configures specific time-frequency domain rules for the user terminal based on the user auxiliary information and QoS information. Specifically, the time-frequency domain rules may include at least one of the following information:

[0283] The starting position of the time domain of available resources;

[0284] The starting position of the available resource frequency domain;

[0285] The long period of available resource time domain, specifically, the long period is used to indicate the resource interval length between each two initial resource transmissions;

[0286] A short period in the time domain of available resources, specifically, the short period is used to indicate the duration of the resource interval between the initial transmission resource and the retransmission resource or between the retransmission resources within a round of transmission;

[0287] Frequency domain hopping granularity A, specifically, the granularity A is used to indicate the resource hopping granularity between every two initial transmission resources;

[0288] Frequency domain hopping granularity B, specifically, the granularity B is used to indicate the resource hopping granularity between the initial transmission resource and the retransmission resource or between the retransmission resources within a transmission round;

[0289] Number of times the initial transmission resource is used;

[0290] The total number of times initial transmission resources and retransmission resources are used in one transmission round.

[0291] Similar to the above-mentioned sending resource pool, the master relay node A may also configure a receiving resource pool for the user terminal. Specifically, the information type included in the receiving resource pool configuration is part or all of the information type included in the sending resource pool configuration information.

[0292] Example 2: Primary relay node A assists the user terminal in performing control plane functions

[0293] Example 2-1: Primary relay node A assists the user terminal in performing measurements on the optional relay nodes

[0294] Specifically, the master relay node A can assist the user terminal in measuring the surrounding relay nodes under the premise of introducing an artificial intelligence algorithm, and feed back the measurement results to the user terminal.

[0295] Step 1: Optionally, the primary relay node A may control the user node to enable measurement of the optional relay node in at least one of the following ways:

[0296] Method 1: The primary relay node A may configure periodic measurement activities for the user terminal.

[0297] Specifically, the primary relay node A may configure at least one of the following parameters for the user terminal:

[0298] Measuring long periods;

[0299] Short cycles are measured within the cycle;

[0300] Number of measurements within a cycle;

[0301] The measurement start offset value within the cycle.

[0302] The user terminal performs measurement on the optional relay nodes according to the periodic configuration.

[0303] Mode 2: Optionally, the primary relay node may indicate to the user terminal whether to perform measurement on the optional relay node by explicitly indicating measurement enable and / or measurement disable.

[0304] Step 2: The primary relay node A performs measurements on the optional relay nodes for the user terminal and feeds back the measurement results to the relay node A. Specifically, the measurement result feedback includes at least one of the following information:

[0305] Permanent group member ID of optional relay node;

[0306] The absolute value of the measurement of the optional relay node;

[0307] The timestamp of the measurement.

[0308] There is no time sequence restriction for the above steps 1 and 2. They can be performed one after the other or in parallel.

[0309] Step 3: The user terminal compares its own measurement results and performs regression analysis.

[0310] Optionally, the primary relay node A can configure a measurement offset threshold for the user terminal. Specifically, after the user terminal receives the measurement report fed back by the primary relay node A, if the offset between the measurement of the primary relay node A and the measurement of the user terminal at the time closest to the timestamp displayed exceeds the configured offset threshold, the user terminal feeds back the measurement offset to the primary relay node A.

[0311] Example 2-2: Primary relay node A assists a user terminal in performing resource pool awareness:

[0312] Specifically, the master relay node A can assist the user terminal in perceiving the configured sending resource pool and selecting resources for the user terminal under the premise of introducing an artificial intelligence algorithm.

[0313] Specifically, when the main relay node A configures a sending resource pool for the user terminal and configures a resource acquisition method based on the main relay node A-assisted perception, the main relay node A can assist the user terminal in performing perception and / or resource pool busyness measurement within the configured resource pool.

[0314] Scenario 1: Perception measurement.

[0315] The master relay node may report all available resource sets in the resource pool to the user terminal.

[0316] An example of a reporting method is as follows: Resource Index (resourceIndex)

[0317] Indicates the available resource candidates within the [T1, T2] window. A value of 1 indicates the resource candidates on the subframe indicated by sl-SubframeRef, from subchannel 0 to sensingSubchannelNumber-1. A value of 2 indicates the resource candidates on the first subframe after the subframe indicated by sl-SubframeRef, from subchannel 0 to sensingSubchannelNumber-1 (if the subchannel number (numSubchannel) of the resource pool is greater than the sensing subchannel number (sensingSubchannelNumber), a value of 101 indicates the resource candidates on the subframe indicated by sl-SubframeRef, from subchannel 1 to sensingSubchannelNumber), and so on.

[0318] (Indicates the available resource candidates within the[T1,T2]window.Value 1 indicates the resource candidate on the subframe indicated by sl-SubframeRef,from subchannel 0 to sensingSubchannelNumber-1.Value 2 indicates the resource candidate on the first subframe following the subframe indicated by sl-SubframeRef,from subchannel 0 to sensingSubchannelNumber-1(Value 101 indicates the resource candidate on the subframe indicated by sl-SubframeRef,from subchannel 1 to sensingSubchannelNumber,if the numSubchannel of the resource pool is larger than sensingSubchannelNumber)and so on.)

[0319] Similar to Example 2-1, primary relay node A can configure periodic measurement activities for user terminals. Similar periodic parameters are used to perform periodic perception measurements on the resource pool. Primary relay node A can configure a perception enable indication and / or a perception disable indication for the user terminal. The perception enable indication can activate the user terminal's perception function for the resource pool. The perception disable indication can deactivate the user terminal's perception function for the resource pool. Additionally, primary relay node A can configure an available resource error threshold for the user terminal.

[0320] Furthermore, when the user terminal receives a perception report from relay node A regarding the resource pool, the user terminal can compare the available resources reported by relay node A with the available resources perceived by the user terminal. Specifically, for all resources within the set of available resources reported by relay node A, if the resource index reported by relay node A is found within the set of available resources perceived by the user terminal itself, the resource index is skipped; if the resource index reported by relay node A cannot be found within the set of available resources perceived by the user terminal, the current resource error is incremented by 1; after traversing the set of available resources reported by relay node A, the resource error number is calculated using the following formula.

[0321] Resource error number = current resource error + |number of resources in the resource set of relay node A - number of resources in the available resource set perceived by the user terminal|.

[0322] If the resource error number is greater than the configured resource error number threshold, the user terminal reports the resource set report of the unmatched resource index (resource index) and the resource error number to the relay node A.

[0323] Scenario 2: Busyness and idleness measurement.

[0324] Further, the master relay node A may report the measured resource pool busyness and idleness and the resource pool busyness and idleness error threshold to the user terminal for the resource pool busyness and idleness measured by the master relay node A. Optionally, the master relay node A may also configure a CBR enable / disable indication for the user terminal.

[0325] When the user terminal receives the resource pool busyness measured by the primary relay node A, the resource pool busyness error = the resource pool busyness measured by the primary relay node A - the resource pool busyness measured by the user terminal.

[0326] If the absolute value of the resource pool busy-idle degree error is greater than the configured resource pool busy-idle degree error threshold, the user terminal reports the resource pool busy-idle degree error to the master relay node A.

[0327] Similar to Scenario 1, primary relay node A can configure periodic measurement activities for the user terminal. Similar periodic parameters are used to periodically measure the busyness of the resource pool. Primary relay node A can configure a busyness enable indication and / or a busyness disable indication for the user terminal. The busyness enable indication can activate the user terminal's busyness measurement function for the resource pool. The busyness disable indication can deactivate the user terminal's busyness measurement function for the resource pool.
