Description

Technical Field

[0001] The present disclosure relates to communication technology, and more particularly to a resource coordination method, device, and storage medium. Background Art

[0002] Device-to-device (D2D) communication is a communication method based on sidelink (SL) transmission technology. For example, vehicle-to-everything (V2X), or the Internet of Vehicles (IoV), which uses D2D communication, has gained widespread adoption. IoV systems utilize direct end-to-end communication, resulting in higher spectrum efficiency and lower transmission latency.

[0003] In a D2D system, multiple terminals can form a communication group. When there are multiple communication groups in the system, especially when the communication groups are very close to each other, interference will occur between the communication groups.

[0082] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0083] The terms "first", "second", etc. in the specification, claims, and above-mentioned figures of the embodiments of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way are interchangeable where appropriate, so that the embodiments of the present disclosure described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or apparatus.

[0084] Figure 1 FIG. 1 is a schematic diagram of a communication system used in an embodiment of the present disclosure. Figure 1 As shown, the communication system includes at least a network device 11 and a terminal device 12. It is understandable that in an actual communication system, there may be one or more network devices 11 and terminal devices 12. Figure 1 One network device is taken as an example, and two terminal devices 12 are taken as an example.

[0085] exist Figure 1 In the figure, the network device 11 can be an access network device, for example, it can be an access device in a Long Term Evolution (LTE) network and its evolved network, such as an evolved base station (eNB or eNodeB), or it can also include a next generation node B (gNB) in a 5G NR system, or a relay station, or a base station in a future new network system, etc.

[0086] The terminal device 12 may also be referred to as a mobile terminal, user equipment (UE), access terminal, subscriber unit, subscriber station, mobile station, mobile station, user terminal, terminal, wireless communication device, user agent, or user apparatus. Specifically, it may be a smartphone, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, or other processing devices connected to a wireless modem, an in-vehicle device, a wearable device, or the like. In the disclosed embodiment, the terminal device has an interface for communicating with a network device.

[0087] In the following embodiments, the terminal device is referred to as terminal for short.

[0088] In sideline communication, according to the network coverage of the communicating terminal, it can be divided into sideline communication within the network coverage, sideline communication with partial network coverage, and sideline communication outside the network coverage, as shown below. Figure 2 , Figure 3 , Figure 4 shown.

[0089] like Figure 2 As shown: in sideline communication within network coverage, all terminals performing sideline communication are within the coverage of the same network device, so that the above terminals can perform sideline communication based on the configuration signaling of the network by receiving the configuration signaling of the network device.

[0090] like Figure 3 As shown in the figure: In the case of partial network coverage for sidelink communication, some terminals performing sidelink communication are located within the coverage area of the network device. These terminals can receive the configuration signaling of the network device and perform sidelink communication according to the configuration of the network device. However, terminals located outside the network coverage area cannot receive the configuration signaling of the network device. In this case, the terminals outside the network coverage area will determine the sidelink configuration based on the pre-configuration information and the information carried in the Physical Sidelink Broadcast Channel (PSBCH) sent by the terminals within the network coverage area, and perform sidelink communication.

[0091] like Figure 4 As shown: for sideline communication outside the network coverage, all terminals performing sideline communication are located outside the network coverage, and all terminals determine the sideline configuration according to the pre-configured information to perform sideline communication.

[0092] In one embodiment of the present disclosure, Figure 5As shown: For sideline communication with a central control node, multiple terminals form a communication group. The communication group has a central control node, which can also be called a cluster head (CH) terminal. The central control node has one of the following functions: responsible for the establishment of the communication group; the joining and leaving of cluster member (CM) terminals; resource coordination, allocating sideline transmission resources to other terminals, receiving sideline feedback information from other terminals; and resource coordination with other communication groups. Figure 5 In the example, terminal UE1 serves as a CH terminal, and UE2 and UE3 serve as CM terminals.

[0093] In NR-V2X, unicast, multicast and broadcast transmission modes are supported. For unicast transmission, there is only one receiving terminal, such as Figure 6 In the example, UE1 and UE2 perform unicast transmission; for multicast transmission, the receiving end is all terminals in a communication group, or all terminals within a certain transmission distance, such as Figure 7 In the example, UE1, UE2, UE3 and UE4 form a communication group, where UE1 sends data and the other terminal devices in the group are all receiving terminals. For the broadcast transmission mode, the receiving terminal is any terminal around the sending terminal, such as Figure 8 UE1 is a transmitting terminal, and the other terminals around it, UE2-UE6, are all receiving terminals.

[0094] The following two transmission modes are supported in sidelink communication. The first mode: The terminal's transmission resources are allocated by the network device, and the terminal sends data on the sidelink according to the resources allocated by the network device; the network device can allocate resources for a single transmission to the terminal, or it can allocate resources for semi-static transmission to the terminal. Figure 2 In the second mode, the terminal is within the coverage of the network, and the network allocates transmission resources for the terminal to use for side transmission. The second mode: the terminal selects a resource in the resource pool to transmit data. Figure 4 In the case where the terminal is outside the coverage area of the cell, the terminal autonomously selects transmission resources from the pre-configured resource pool for side transmission; or Figure 2 In the process, the terminal autonomously selects transmission resources from the resource pool configured by the network for side transmission.

[0095] Furthermore, based on the above two modes, for the communication group, the CH terminal can also allocate transmission resources to other terminals, for example, allocating transmission resources to other terminals in the communication group in the resource pool configured by the network, or allocating transmission resources to other terminals in the communication group in the resource pool pre-configured by the network.

[0096] The method of the embodiment of the present disclosure is applicable to a variety of scenarios, and is described below using the Internet of Vehicles system and smart home scenarios as examples.

[0097] For the Internet of Vehicles system: multiple vehicles form a communication group; the CH terminal allocates transmission resources to the CM terminal in the group. When two communication groups are very close to each other, interference coordination between the two communication groups needs to be considered;

[0098] In-vehicle communication scenarios: A vehicle contains a variety of terminal devices, such as speakers, audio equipment, cameras, and rearview mirrors, all of which can be controlled by a central control node within the vehicle. For example, the terminals within a vehicle constitute a communication group or system, and different vehicles have different communication groups. When one vehicle moves near another, interference coordination between the communication groups of the vehicles must be considered.

[0099] For home or indoor smart home scenarios: In smart home scenarios, the terminals in the home or indoor have communication functions, and the terminals in the home can form a communication group. The communication group usually has a central control node or CH terminal, such as a smartphone, smart TV, and user terminal equipment (CPE). For example, the terminals in the same home constitute a communication group, and different homes have different communication groups. The communication group within a home needs to consider interference coordination with the communication groups of other homes (such as neighbors).

[0100] In a scenario with multiple communication groups, transmission resources between different communication groups may conflict, and interference is likely to occur between the communication groups.

[0101] The technical concept of the method of the embodiment of the present disclosure is as follows: detecting other second communication groups existing around the current first communication group, and performing resource coordination to avoid or reduce interference between the first communication group and the second communication group.

[0102] The following specific embodiments are used to describe the technical solution of the present disclosure in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0103] The resource coordination method provided by the present disclosure is described below.

[0104] Figure 9 This is a flow chart of an embodiment of the resource coordination method provided by the present disclosure, such as Figure 9 As shown, the specific implementation steps of this embodiment include:

[0105] Step 101: The first terminal determines that a second communication group exists.

[0106] The first terminal is a terminal in the first communication group.

[0107] To fully utilize system transmission resources, a communication group can use all network-allocated transmission resources when no other second communication groups exist (or the communication groups are far apart, minimizing interference). However, if a second communication group exists, for example, if it is very close to the first communication group, the presence of the second communication group can interfere with the communication of the terminals in the first communication group, necessitating resource coordination. Therefore, it is first necessary to detect whether there are other second communication groups.

[0108] In the embodiment of the present disclosure, the first terminal is, for example, a group head terminal of the first communication group. The group head terminal is usually a terminal with a high capability level, such as having strong signal processing capabilities and not being subject to power restrictions.

[0109] In one embodiment, the number of the second communication groups may be one or more.

[0110] In this step, the existence of the second communication group may be determined by the first terminal's own detection result of the second communication group, or by the detection results of other terminals in the first communication group, which is not limited in the present disclosure.

[0111] The method for detecting the second communication group can, for example, be based on the measurement results of the signal or channel sent by the terminal of the second communication group, or by detecting whether there is identification information different from the identification information of the first communication group, etc., to determine whether the second communication group exists. The identification information of the communication group can, for example, be carried in certain signals or channels, such as synchronization signals, broadcast channels, etc.

[0112] Step 102: The first terminal performs resource coordination.

[0113] When the first terminal determines that there are other second communication groups around, resource coordination is required to avoid or reduce interference between the first communication group and the second communication group.

[0114] When performing resource coordination, for example, the terminals in the first communication group can avoid using the transmission resources used or reserved by other terminals (for example, the terminals in the current first communication group and the terminals in the other second communication groups), thereby avoiding resource conflicts with other terminals and reducing interference; for example, it can negotiate with other second communication groups so that each communication group uses different transmission resources; for example, it can also notify other second communication groups of the transmission resources used by the first communication group, or the transmission resources used to send a certain signal or channel, so as to avoid other second terminals from using these transmission resources to reduce interference, etc.

[0115] In the method of this embodiment, the first terminal determines other second communication groups existing around the current first communication group, performs resource coordination, reduces resource conflicts, and thus can reduce interference between the first communication group and the second communication group.

[0116] In one embodiment, there are multiple ways to determine the existence of the second communication group. Several possible implementations are described in detail below:

[0117] One implementation method A:

[0118] The first terminal determines that the second communication group exists according to the detection result of the first terminal.

[0119] In this manner, the first terminal detects the existence of the second communication group by itself, and determines the existence of the second communication group based on the detection result of the first terminal.

[0120] The first terminal may determine the existence of the second communication group based on its own detection result in the following ways:

[0121] Method a:

[0122] If the detection result of the first terminal includes: second identification information, the first terminal determines that the second communication group exists, wherein the second identification information is different from the first identification information of the first communication group.

[0123] Specifically, different communication groups may have different identification (ID) information, which may be carried in certain signals or channels transmitted by the terminal. Therefore, the presence of a second communication group can be determined by detecting the identification information. If second identification information different from the first identification information of the first communication group is detected, the presence of the second communication group is determined.

[0124] In one embodiment, the first terminal detects a synchronization signal or a broadcast channel to obtain the second identification information.

[0125] In one embodiment, for the same communication group, in order to maintain synchronization between terminals in the group, the group head terminal (or central control node) usually sends a synchronization signal. The synchronization signal carries the identification information of the communication group. The synchronization signals sent by the group head terminals of different communication groups correspond to different identification information. Therefore, in one embodiment, the first terminal can detect the ID in the synchronization signal and determine whether a second communication group exists based on the detected ID.

[0126] For example, when the first terminal detects an ID different from the ID of the first communication group, it can be determined that the second communication group exists.

[0127] In one embodiment, a broadcast channel may also be detected, and whether the second communication group exists may be determined based on ID information in the broadcast channel.

[0128] For example, Figure 10 As shown, CH1, UE1, and UE2 are the first communication group, and CH2, UE3, and UE4 are the second communication group. CH1 and CH2 send synchronization signals, corresponding to synchronization signal identifiers (Synchronization Signal Identity, SSID for short) 1 and SSID 2, respectively. CH1 detects the synchronization signal sent by CH2 and determines that its corresponding identification information is SSID 2. It has different identification information from the synchronization signal sent by CH1, so it can be determined that there is a second communication group.

[0129] Figure 10 In the embodiment, the first communication group and the second communication group may be asynchronous. When the central control node CH1 of the first communication group receives an uplink signal sent by other terminals in the communication group, that moment may correspond to the downlink transmission of the second communication group. Therefore, CH1 can receive the synchronization signal sent by the central control node CH2 of the second communication group. Alternatively, in other embodiments, the time slots for uplink transmission and downlink transmission between the first communication group and the second communication group are different. For example, a time slot used for uplink transmission for the first communication group may be used for downlink transmission for the second communication group. Therefore, CH1 can receive the synchronization signal sent by the central control node CH2 of the second communication group.

[0130] In one embodiment, the second identification information includes at least one of the following information: a Radio Network Temporary Identity (RNTI), communication group identification information, SSID, or a Sidelink Synchronization Signal Identity (SLSS ID).

[0131] In the above specific implementation, by detecting identification information, other second communication groups around the first communication group can be identified, which is easy to operate and can then coordinate resources to reduce interference between the first communication group and the second communication group.

[0132] Method b:

[0133] The first terminal measures a signal or channel sent by the second terminal;

[0134] If the detection result includes that the measurement result of the first terminal on the signal or channel from the second terminal exceeds the first threshold, the first terminal determines that the second communication group exists, wherein the second terminal is a terminal in the second communication group.

[0135] Specifically, a first terminal in a first communication group may receive signals or channels from other communication groups and measure the signals or channels of the other communication groups. If the measurement result exceeds a first threshold, the presence of a second communication group may be determined. If the measurement result is less than the first threshold, the other communication groups may be considered to be far away and resource coordination may not be required.

[0136] Exceeding the threshold refers to being greater than or equal to the first threshold.

[0137] In one embodiment, the first threshold is pre-configured, configured on the network side, or configured by the first terminal.

[0138] The second terminal may be a group head terminal or a group member terminal of the second communication group, which is not limited in this embodiment of the present disclosure.

[0139] In one embodiment, the measurement result includes a measurement result of at least one of the following signals: a synchronization signal, a demodulation reference signal (DMRS), a channel state information reference signal (CSI-RS), or a sounding reference signal (SRS); or the measurement result includes a measurement result of at least one of the following channels: PSBCH, physical sidelink shared channel (PSSCH), physical sidelink control channel (PSCCH), physical sidelink feedback channel (PSFCH), physical broadcast channel (PBCH), physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), physical downlink control channel (PDCCH), or physical uplink control channel (PUSCH). Channel, referred to as PUCCH).

[0140] In one embodiment, the synchronization signal may include at least one of the following signals: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a sidelink primary synchronization signal (S-PSS), and a sidelink secondary synchronization signal (S-SSS).

[0141] In one embodiment, the DMRS includes one of the following: PDSCH DMRS, PDCCH DMRS, PBCH DMRS, PUSCH DMRS, PUCCH DMRS, PSSCH DMRS, PSCCH DMRS, PSBCH DMRS.

[0142] It should be understood that the signal or channel in this embodiment can be any signal or channel transmitted between the group head and group members, or between group members, and the present disclosure is not limited to this.

[0143] In one embodiment, the measurement result includes at least one of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and Received Signal Strength Indicator (RSSI). For example, if the measurement result is a signal measurement result, the measurement result includes at least one of the following: RSRP or RSRQ; if the measurement result is a channel measurement result, the measurement result includes at least one of the following: SINR or RSSI.

[0144] If the measurement is for a signal, the measurement quantity is, for example, RSRP, RSRQ, etc.; if the terminal is for a channel measurement, the measurement quantity is, for example, SINR, RSSI, etc.

[0145] For example, for a communication group composed of vehicles, terminals in the communication group transmit data through side links. Therefore, the first terminal in the first communication group can measure the side signals or side channels of other communication groups to determine whether there is a second communication group.

[0146] For example, in the scenario of in-vehicle communication, the communication between the central control node and other terminals in the vehicle is usually carried out through uplink and downlink channels (PDSCH, PDCCH, PUSCH, PUCCH). Therefore, the first terminal can measure the uplink and downlink channels or signals sent by the terminal in another vehicle or the terminal in another communication group, and then determine whether there is a second communication group. In the in-vehicle scenario, since the communication groups of different vehicles may be asynchronous, when the central control node of the first communication group receives the uplink channel sent by other terminals in the communication group, this moment may correspond to the downlink transmission of another communication group. Therefore, the central control node can receive the downlink channel and downlink signal sent by the central control node of the other communication group.

[0147] In the above specific implementation, other second communication groups around the first communication group can be identified through measurement results of signals or channels, and then resource coordination can be performed to reduce interference between the first communication group and the second communication group.

[0148] In the above two methods, the first terminal determines other second communication groups existing around the first communication group through its own detection results.

[0149] Another implementation method B:

[0150] The first terminal obtains first indication information;

[0151] The first terminal determines the existence of the second communication group according to the first indication information; wherein the first indication information is used to indicate the existence of the second communication group.

[0152] In one embodiment, the first terminal obtains the first indication information, including:

[0153] The first terminal receives first indication information sent by a third terminal, where the third terminal is a terminal in the first communication group.

[0154] The third terminal may be any group member terminal in the first communication group.

[0155] Specifically, the first terminal may determine the existence of the second communication group based on the first indication information of other third terminals in the first communication group. The first indication information indicates the existence of the second communication group, and the second indication information may include information about the second communication group, such as identification information of the second communication group and information about terminals in the second communication group.

[0156] The manner in which the third terminal detects the second communication group may refer to the manner in which the first terminal detects the second communication group in the aforementioned embodiment, such as manner a and manner b, which will not be described in detail here.

[0157] For example, Figure 11As shown, CH1, UE1, and UE2 are the first communication group, and CH2, UE3, and UE4 are the second communication group. CH1 and CH2 send synchronization signals, corresponding to SSID 1 and SSID2, respectively. UE2 detects the synchronization signal sent by CH2 and determines that its corresponding identification information is SSID2, which has different identification information from the synchronization signal sent by CH1, so it can be determined that there is a second communication group.

[0158] Optionally, the first indication information is carried in sidelink control information (SCI), data media access layer control element (MAC Control Element, MAC CE) or radio resource control (PC5 Radio Resource Control, PC5-RRC) signaling; or,

[0159] The first indication information is carried in the PUCCH; or,

[0160] The first indication information is carried in the PUSCH.

[0161] Optionally, the first indication information is carried in a transmission channel between the group member terminal and the group head terminal.

[0162] In one embodiment, the third terminal is a terminal configured by the first terminal for detecting the second communication group, or the third terminal is a terminal in the first communication group whose measurement result of the signal or channel from the first terminal is less than or equal to the second threshold.

[0163] The third terminal can be a terminal configured by the first terminal to detect the existence of the second communication group, or it can be any group of member terminals in the first communication group that detects the existence of the second communication group based on the measurement results. For example, if the measurement result of the signal or channel of the first terminal is less than or equal to the second threshold, then the terminal acts as the third terminal to detect the existence of the second communication group.

[0164] In one embodiment, the second threshold is pre-configured, configured on the network side, or configured by the first terminal.

[0165] For example, when the RSRP measured by the third terminal of the first terminal is lower than the second threshold, it can be considered that the third terminal is far away from the first terminal, or is located at the edge of the first communication group. Such terminals are more likely to detect whether there are other communication groups around, so the existence of the second communication group is detected through the third terminal.

[0166] In one embodiment, the first terminal is configured to detect resources of the second communication group, such as resources for detecting identification information or resources for measuring signals or channels sent by terminals of the second communication group. The resources may include time domain resources and / or frequency domain resources.

[0167] For example, the first terminal configures a time window for the first terminal or the third terminal, and the first terminal or the third terminal measures a signal or channel sent by a terminal of the second communication group within the time window;

[0168] For another example, the first terminal configures a pattern for detecting the second communication group for the first terminal or the third terminal, and determines the time domain and / or frequency domain resources for detecting the second communication group based on the pattern.

[0169] In the above specific implementation, the first terminal determines other second communication groups around the first communication group based on the detection results of other third terminals, and then performs resource coordination to reduce interference between the first communication group and the second communication group.

[0170] In one embodiment, the first terminal needs to confirm whether to perform resource coordination before performing resource coordination, for example, performing resource coordination when certain conditions are met. For example, when the two communication groups are far apart, interference is low and resource coordination is not required; when the two communication groups are close together and interference is strong, interference coordination is required.

[0171] In one embodiment, for the case where the first terminal detects the existence of the second communication group (ie, implementation A), if the measurement result of the first terminal on the signal or channel from the second terminal exceeds a third threshold, the first terminal performs resource coordination.

[0172] Specifically, in this approach, interference coordination is triggered only when the first terminal's measurement of a signal or channel from the second terminal meets a preset condition. For example, if the first terminal's measurement of a signal or channel sent by the second terminal exceeds a third threshold, the first terminal performs resource coordination. For example, if the measurement does not exceed the third threshold, it indicates that the interference from the second communication group to the second communication group is minimal, and resource coordination may not be performed.

[0173] In another embodiment, for the case where the first terminal determines the existence of the second communication group through detection results of other third terminals (ie, implementation B), the method further includes:

[0174] The first terminal receives second indication information of the fourth terminal in the first communication group; the second indication information is used by the first terminal to determine to perform resource coordination.

[0175] Specifically, the first terminal determines to perform resource coordination according to the received second indication information sent by the fourth terminal; otherwise, even if it is determined that the second communication group exists, resource coordination is not required.

[0176] In one embodiment, the second indication information is sent by the fourth terminal when the measurement result of the second communication group exceeds a sixth threshold. If the measurement result does not exceed the sixth threshold, it indicates that the interference is small and no reporting is required.

[0177] For example, when the fourth terminal in the communication group measures RSRP and RSRQ for the signals of other communication groups, or measures RSSI and SINR for the channels of other communication groups, if the measurement result is higher than the sixth threshold, it means that the interference from other communication groups is strong, and the second indication information will be reported to the first terminal of the group head.

[0178] The fourth terminal and the third terminal may be the same terminal in the first communication group, or different terminals, which is not limited in this embodiment of the present disclosure.

[0179] In one embodiment, the second indication information is used to instruct the first terminal to perform resource coordination; or,

[0180] The second indication information is used to indicate that the measurement result of the fourth terminal on the terminals in the second communication group exceeds a fourth threshold; or,

[0181] The second indication information includes measurement results of the fourth terminal on the terminals in the second communication group.

[0182] Specifically, the second indication information may directly instruct the first terminal to perform resource coordination, eliminating the need for the first terminal to make further determinations. Alternatively, the second indication information may indicate that if the measurement result exceeds a fourth threshold, the first terminal may determine to perform resource coordination. The fourth threshold and the sixth threshold may be the same or different.

[0183] Alternatively, the second indication information includes measurement results of the fourth terminal on the terminals in the second communication group, and the first terminal determines whether to perform resource coordination based on the measurement results of the fourth terminal on the terminals in the second communication group.

[0184] In one embodiment, if the measurement result exceeds a fifth threshold, the first terminal performs resource coordination, wherein the fifth threshold and the sixth threshold may be the same or different.

[0185] In one embodiment, the second indication information is carried in SCI, MAC CE of data, or PC5-RRC signaling; or,

[0186] The second indication information is carried in the PUCCH; or,

[0187] The second indication information is carried in the PUSCH.

[0188] Optionally, the second indication information is carried in a transmission channel between the group member terminal and the group head terminal.

[0189] Among them, any threshold among the third threshold to the sixth threshold can be pre-configured, configured on the network side, or configured by the first terminal.

[0190] In the above specific implementation, before performing resource coordination, it is determined whether to perform resource coordination. In the case of less interference, resource coordination may not be required, thereby simplifying the operation of the first terminal and saving power consumption.

[0191] In one embodiment, resource coordination for the first terminal may be performed in a variety of ways, for example, the following ways may be used:

[0192] One implementation method 1-1:

[0193] The first terminal sends third indication information to the terminals in the first communication group, where the third indication information is used to instruct the terminals in the first communication group to autonomously select transmission resources.

[0194] Specifically, the group head terminal can usually allocate resources to the group member terminals in the communication group, or the transmission resources of the group member terminals are allocated by the network side. In order to avoid interference between terminals, the first terminal can instruct the terminals in the first communication group to autonomously select transmission resources.

[0195] The terminals in the first communication group may also include the third terminal and the fourth terminal in the aforementioned embodiment.

[0196] When the group head terminal allocates transmission resources to group member terminals within a communication group, the group member terminals generally do not need to listen and only need to transmit data using the resources allocated by the group head terminal. In one embodiment, when group member terminals within a communication group autonomously select transmission resources, the group member terminals within the communication group generally need to obtain transmission resources through listening. During the listening process, the terminals can avoid selecting transmission resources already used or reserved by other terminals (including terminals within the communication group and terminals within other communication groups), thereby avoiding resource conflicts with terminals in other communication groups and reducing interference.

[0197] In the above specific implementation manner, the terminals in the first communication group autonomously select transmission resources, which can avoid selecting transmission resources that have been used or reserved by other terminals (including terminals in this communication group and terminals in other communication groups), thereby avoiding resource conflicts with terminals in other communication groups and reducing interference.

[0198] In one embodiment, the third indication information is carried in SCI, MAC CE of data, or PC5-RRC signaling; or,

[0199] The third indication information is carried in the PDCCH; or,

[0200] The third indication information is carried in the PDSCH.

[0201] One implementation method 1-2:

[0202] The first terminal sends fourth indication information to the terminals in the first communication group, where the fourth indication information is used to instruct the activation of the autonomous listening mode of the terminals in the first communication group.

[0203] Specifically, the group head terminal can usually allocate resources to the group member terminals in the communication group, or the transmission resources of the group member terminals are allocated by the network side. In this case, the group member terminals do not need to listen. In order to avoid interference between terminals, the first terminal can send an indication message to the terminals in the first communication group. The indication message is used to indicate the activation of the autonomous listening mode of the terminal, or to indicate the activation of the listening function. After activating the autonomous listening mode, the terminals in the first communication group can avoid selecting transmission resources that have been used or reserved by other terminals (including terminals in this communication group and terminals in other communication groups) by listening, thereby avoiding resource conflicts with terminals in other communication groups and reducing interference.

[0204] In the above specific implementation manner, the terminals in the first communication group can avoid selecting transmission resources that have been used or reserved by other terminals (including terminals in this communication group and terminals in other communication groups) by listening, thereby avoiding resource conflicts with terminals in other communication groups and reducing interference.

[0205] In one embodiment, the fourth indication information is carried in SCI, MAC CE of data, or PC5-RRC signaling; or,

[0206] The fourth indication information is carried in the PDCCH; or,

[0207] The fourth indication information is carried in the PDSCH.

[0208] One implementation method 1-3:

[0209] The first terminal receives available resource information and / or unavailable resource information sent by terminals in the first communication group;

[0210] The first terminal coordinates resources within the first communication group according to the available resource information and / or the unavailable resource information.

[0211] Optionally, the first terminal receives resource indication information sent by terminals in the first communication group, and coordinates resources in the first communication group according to the resource indication information. Specifically, the resource indication information may include available resource indication information and / or unavailable resource indication information.

[0212] Specifically, the terminals in the first communication group can determine which resources are available resources or unavailable resources (i.e., transmission resources with strong interference) by listening. The terminals in the first communication group can report available resource information and / or unavailable resource information to the first terminal. For example, the available resource information and / or unavailable resource information can be transmitted to the first terminal in the form of a resource collection.

[0213] These available resource information and / or unavailable resource information can assist the first terminal in scheduling resources. For example, the first terminal allocates transmission resources in the available resource set to the terminals in the first communication group, or avoids allocating transmission resources in the unavailable resource set to the terminals in the first communication group, thereby achieving the purpose of avoiding or reducing interference between communication groups.

[0214] In the above-mentioned specific implementation manner, the terminals in the first communication group can send available resource information and / or unavailable resource information to the first terminal by listening. The first terminal allocates resources to the terminals in the first communication group based on the available resource information and / or unavailable resource information, avoiding allocating transmission resources within the unavailable resource set to the terminals in the first communication group, thereby achieving the purpose of avoiding or reducing interference between communication groups.

[0215] One implementation method 1-4:

[0216] The first terminal allocates resources to the first communication group and the second communication group, wherein the resources of the first communication group and the resources of the second communication group are different in the time domain and / or frequency domain;

[0217] The first terminal sends resource information of the second communication group to the terminals of the second communication group.

[0218] Specifically, when there are no other communication groups around, the first communication group can use all transmission resources allocated by the network to increase the transmission rate, but when there are other communication groups around, different transmission resources can be used between communication groups, for example, orthogonal transmission resources can be used to reduce interference between communication groups.

[0219] For example, communication groups multiplex transmission resources through time division and / or frequency division. For example, if the system bandwidth is 20 MHz, when two communication groups need to coordinate resources, each communication group can use 10 MHz bandwidth for data transmission to avoid interference.

[0220] Time division multiplexing means that different communication groups use different time resources for transmission;

[0221] Frequency division multiplexing means that different communication groups use different frequency domain resources for transmission.

[0222] In one embodiment, the terminals in the second communication group may select transmission resources according to the resource information of the second communication group allocated by the first terminal, thereby reducing interference between the first communication group and the second communication group.

[0223] The first terminal may send the resource information of the second communication group to the group head terminal or group member terminals of the second communication group, which is not limited in this embodiment of the present disclosure.

[0224] In one embodiment, for example, the group head terminal in the second communication group can coordinate resources based on the resource information of the second communication group allocated by the first terminal, and allocate resources to the group member terminals in the second communication group, thereby reducing interference between the first communication group and the second communication group.

[0225] In one embodiment, the resources of the first communication group and the second communication group are resources using different channels; or,

[0226] The resources of the first communication group and the second communication group are resources using different sub-bands; the sub-band includes at least one physical resource block (PRB); or,

[0227] The resources of the first communication group and the second communication group are resources using different interlace PRBs, and the interlace PRBs include M non-continuous PRBs in the frequency domain; M is an integer greater than 0.

[0228] For example, in an unlicensed spectrum, one channel corresponds to a bandwidth of 20 MHz. Transmission resources may include multiple channels. When resources are coordinated between communication groups, different communication groups may use different channels.

[0229] For example, a subband includes multiple PRBs. In sideline communications, frequency domain resources can be divided into multiple subbands, each subband includes N PRBs (for example, N = 5, 10, 15, 20, 50, 100, etc.). When resources are coordinated between multiple communication groups, different communication groups can use different subbands for data transmission.

[0230] For comb-tooth PRB: the comb-tooth PRB includes M non-continuous PRBs in the frequency domain, and a comb-tooth PRB pattern is composed of one PRB in every K PRBs. For example, for a bandwidth of 20 MHz, a subcarrier spacing of 15 kHz, and a system bandwidth including 100 PRBs, if K = 10, that is, one of every 10 PRBs constitutes a comb-tooth PRB pattern. For example, PRB 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 is a comb-tooth PRB pattern, and PRB 1, 11, 21, 31, 41, 51, 61, 71, 81, 91 is another comb-tooth PRB pattern, and so on. The system includes a total of 10 comb-tooth PRB patterns. When two communication groups perform resource coordination, different communication groups can use different comb-tooth PRB patterns. For example, the first communication group uses the first to fifth comb-tooth PRB patterns, and the second communication group uses the sixth to tenth comb-tooth PRB patterns.

[0231] In the above specific implementation, the first terminal allocates resources to the first communication group and the second communication group, and the terminals in the second communication group communicate according to the resources allocated to them by the first terminal. Since the resources of the first communication group and the resources of the second communication group are different in the time domain and / or frequency domain, the purpose of avoiding or reducing interference between the communication groups is achieved.

[0232] One implementation method 1-5

[0233] The first terminal sends fifth indication information to the terminals in the second communication group, where the fifth indication information includes one or more of the following information:

[0234] Channel information used by terminals in the first communication group;

[0235] resource pool configuration information of the first communication group;

[0236] semi-static transmission resource information of terminals in the first communication group;

[0237] Overload indicator (OI) information;

[0238] High Interference Indicator (HII) information; or

[0239] A first set of transmission resources of a first communication group.

[0240] Specifically, the first communication group may send fifth indication information to terminals in the second communication group. For example, the fifth indication information includes resource usage information of terminals in the first communication group, so as to prevent terminals in the second communication group from using resources of the first communication group. For example, channel information used by terminals in the first communication group, resource pool configuration information of the first communication group, and semi-static transmission resource information of terminals in the first communication group may be included.

[0241] For example, the first terminal may further send OI information and / or HII information to the terminals in the second communication group to indicate the interference situation of the first communication group.

[0242] In one embodiment, the first communication group can exchange the more important transmission resources of the first communication group with the terminals in the second communication group. These transmission resources are usually resources that do not want to be interfered with by other terminals, such as high-priority transmission resources, which are sent to the terminals in the second communication group through the first transmission resource set so that the terminals in the second communication group do not use these transmission resources, thereby reducing interference.

[0243] In one embodiment, the terminals in the second communication group can coordinate the resources in the second communication group based on the received fifth indication information to avoid or reduce the use of transmission resources used by the terminals in the first communication group, thereby reducing interference, wherein the fifth indication information is, for example, channel information used to indicate the use of terminals in the first communication group, or the first transmission resource set of the first communication group.

[0244] The terminal in the second communication group may be a group head terminal or a group member terminal of the second communication group, which is not limited in the present disclosure.

[0245] In one embodiment, the resources in the first transmission resource set are used to transmit one or more of the following signals: a sounding reference signal (SRS), a channel state information measurement reference signal (CSI-RS), a system information block (SIB), control information, resource scheduling information, and ultra-reliable low-latency communication (URLLC) data. The first terminal in the first communication group sends the transmission resource set to the terminal in the second communication group, and the terminal in the second communication group avoids using the transmission resources of the transmission resource set, thereby reducing interference to the first communication group.

[0246] In one embodiment, the fifth indication information is carried in at least one of the following signalings:

[0247] Broadcast channel signaling, SCI, MAC CE, PC5-RRC signaling.

[0248] In the above specific implementation, the first terminal sends the resource usage of the first communication group to the terminals in the second communication group. The terminals in the second communication group can coordinate resources according to the resource usage of the first communication group, thereby avoiding or reducing interference between communication groups.

[0249] The following example shows the resource coordination process between communication groups:

[0250] Example 1: Figure 12 As shown, UE1 is the terminal of communication group 1, CH1 is the group head terminal of communication group 1, UE3 is the terminal of communication group 2, and CH2 is the group head terminal of communication group 2; CH1 allocates transmission resources to UE1, and CH2 allocates transmission resources to UE3. When the two communication groups are far apart, the two communication groups can use all the transmission resources allocated by the network; when the two communication groups are close to each other, the terminal UE1 in communication group 1 can detect the existence of communication group 2, for example, by detecting the synchronization signal. If the result of UE1 measuring the signal or channel sent by CH exceeds the threshold, it will send an indication message to CH1 to notify CH1 that there are other communication groups around. Resources can be coordinated between CH1 and CH2. For example, transmission resources are used in a frequency division multiplexing manner, that is, each communication group uses half of the frequency domain resources, and schedules the terminals in the group separately in their respective communication groups.

[0251] Example 2: Figure 13 As shown, similar to Example 1, Example 2 differs from Example 1 in that the resource coordination method is different. When CH1 receives the indication information reported by UE1 and determines that there are other communication groups around, CH1 can modify the resource allocation method of the terminals in the group, from allocating transmission resources to the group head terminal to the terminal independently selecting transmission resources; in the terminal's autonomous selection of transmission resources, the terminal obtains transmission resources by listening. During the listening process, it can avoid selecting transmission resources that have been used or reserved by other terminals, thereby achieving interference between terminals in two communication groups.

[0252] Figure 14 A flowchart of another embodiment of the resource coordination method provided by the present disclosure is shown as follows: Figure 14 As shown, the specific implementation steps of this embodiment include:

[0253] Step 201: The third terminal determines that a second communication group exists; the third terminal is a terminal in the first communication group.

[0254] In this embodiment, the third terminal may be a member terminal of the first communication group. The third terminal detects the existence of the second communication group and determines the existence of the second communication group based on the detection result of the third terminal.

[0255] Step 202: The third terminal sends first indication information to the first terminal, where the first terminal is a terminal in the first communication group. The first indication information is used to indicate the existence of the second communication group.

[0256] After detecting the existence of the second communication group, the third terminal sends first indication information to the first terminal. The first terminal can determine the existence of the second communication group based on the first indication information and then coordinate resources to avoid or reduce interference between the first communication group and the second communication group.

[0257] In one embodiment, the third terminal determines that the second communication group exists, which can be achieved by:

[0258] The third terminal determines, according to the detection result of the third terminal, that the second communication group exists.

[0259] In one embodiment, the third terminal may determine the existence of the second communication group according to the detection result of the third terminal in the following ways:

[0260] Method a:

[0261] If the detection result of the third terminal includes: second identification information, the third terminal determines that the second communication group exists, wherein the second identification information is different from the first identification information of the first communication group.

[0267] If the detection result of the third terminal includes: a measurement result of the third terminal on the signal or channel from the second terminal exceeds a first threshold, the third terminal determines that the second communication group exists, wherein the second terminal is a terminal in the second communication group.

[0268] In one embodiment, the first threshold is pre-configured, configured on the network side, or configured by the first terminal of the first communication group.

[0269] In one embodiment, the third terminal is a terminal configured by the first terminal to detect the second communication group, or the third terminal is a terminal in the first communication group whose measurement result of the signal or channel from the first terminal is less than or equal to the second threshold.

[0270] In one embodiment, resources used to detect the second communication group are configured for the first terminal; the resources include time domain resources and / or frequency domain resources.

[0271] In one embodiment, the method further comprises:

[0272] The third terminal sends second indication information to the first terminal, where the second indication information is used by the first terminal to determine to perform resource coordination.

[0273] In one embodiment, the second indication information is used to instruct the first terminal to perform resource coordination; or,

[0274] The second indication information is used to indicate that a measurement result of the third terminal on the second communication group exceeds a fourth threshold; or,

[0275] The second indication information includes a measurement result of the third terminal on the second communication group.

[0276] In one embodiment, the second indication information is sent by the third terminal when the measurement result of the second communication group exceeds a sixth threshold.

[0277] In one embodiment, the measurement result includes a measurement result of at least one of the following signals: a synchronization signal, a DMRS, a CSI-RS, or an SRS; or the measurement result includes a measurement result of at least one of the following channels: PSBCH, PSSCH, PSCCH, PSFCH, PBCH, PDSCH, PUSCH, PDCCH, or PUCCH.

[0278] In one embodiment, if the measurement result is a signal measurement result, the measurement result includes at least one of the following: RSRP or RSRQ;

[0279] If the measurement result is a channel measurement result, the measurement result includes at least one of the following: SINR or RSSI.

[0280] In one embodiment, the method further comprises:

[0281] The third terminal receives third indication information sent by the first terminal, where the third indication information is used to instruct terminals in the first communication group to autonomously select transmission resources.

[0282] In one embodiment, the method further comprises:

[0283] The third terminal receives fourth indication information sent by the first terminal, where the fourth indication information is used to instruct activation of the autonomous listening mode of the terminals in the first communication group.

[0284] In one embodiment, the method further comprises:

[0285] The third terminal sends available resource information and / or unavailable resource information to the first terminal; the available resource information and / or the unavailable resource information are used by the first terminal to coordinate resources within the first communication group.

[0286] The implementation principle and technical effects of the above-mentioned third terminal side method are similar to those of the above-mentioned first terminal side method, and will not be repeated here.

[0287] Figure 15a A flow chart of another embodiment of the resource coordination method provided by the present disclosure is as follows Figure 15a As shown, the specific implementation steps of this embodiment include:

[0288] Step 301: The second terminal receives resource information of the second communication group sent by the first terminal, where the first terminal is a terminal in the first communication group and the second terminal is a terminal in the second communication group; the resources of the first communication group and the resources of the second communication group are different in time domain and / or frequency domain.

[0289] Specifically, the second terminal receives information sent by the first terminal, such as resource information of the second communication group, wherein, in order to avoid interference between the first communication group and the second communication group, the resources of the first communication group and the second communication group are different in time domain and / or frequency domain.

[0290] Optionally, the resources of the first communication group and the resources of the second communication group may be allocated by the first terminal or allocated by the network side.

[0291] Step 302: The second terminal performs resource coordination according to the resource information of the second communication group.

[0292] In this step, the second terminal coordinates the resources of the second communication group based on the received resource information of the second communication group, for example, allocating resources to the terminals in the second communication group. In one embodiment, the second terminal may determine the resources available to the terminals in the second communication group, for example, determining a set of available second transmission resources, and the terminals in the second communication group may use the resources in the second transmission resource set for data transmission.

[0293] The second terminal may be a group head terminal or a group member terminal in the second communication group, which is not limited in the embodiment of the present disclosure.

[0294] In one embodiment, the resources of the first communication group and the second communication group are resources using different channels; or,

[0296] The resources of the first communication group and the second communication group are resources using different comb-tooth PRBs, and the comb-tooth PRBs include M non-continuous PRBs in the frequency domain; M is an integer greater than 0.

[0297] In one embodiment, step 302 may be implemented as follows:

[0298] The second terminal determines, based on the resource information of the second communication group, a second transmission resource set used by the second communication group;

[0299] The second terminal uses the second transmission resource set for data transmission; or, the second terminal allocates transmission resources to terminals in the second communication group according to the second transmission resource set.

[0300] In one embodiment, the terminals in the second communication group may use the resources in the second transmission resource set for data transmission; wherein the second terminal may be a group head terminal or a group member terminal in the second communication group.
