In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," and the like in the description and in the claims, and in the foregoing drawings, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present application. As shown in fig. 1, the communication system includes at least a network device 11 and a terminal device 12. It is understood that in an actual communication system, there may be one or more network devices 11 and one or more terminal devices 12, where the network device in fig. 1 is taken as an example, and the terminal device 12 is taken as an example.

In fig. 1, the network device 11 may be an access network device, for example, an access device in an LTE network and an evolved network thereof, such as an evolved Node B (eNB or eNodeB), or may also include a next generation Node B (gNB) in a 5G NR system, or a relay station, or a base station in a new network system in the future, and so on.

Terminal Equipment 12 may also be referred to as a mobile terminal, user Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a User terminal, a terminal, wireless communication Equipment, a User agent, or a User Equipment. Specifically, the device may be a smart phone, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA) device, a handheld device with a wireless communication function or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, or the like. In the embodiment of the application, the terminal device has an interface for communicating with the network device.

In the following embodiments, the terminal device is simply referred to as a terminal.

In the sidestream communication, according to the network coverage of the terminal performing communication, the sidestream communication is divided into the network coverage inside communication, the partial network coverage sidestream communication, and the network coverage outside communication, as shown in fig. 2, fig. 3, and fig. 4, respectively.

As shown in fig. 2: in the communication inside the network coverage, all terminals performing the sidestream communication are within the coverage area of the same network device, so that the terminals can perform the sidestream communication based on the configuration signaling of the network device by receiving the configuration signaling of the network device.

As shown in fig. 3: in the case of partial network coverage sidestream communication, a part of terminals performing sidestream communication is located in the coverage area of the network device, and the part of terminals can receive the configuration signaling of the network device and perform sidestream communication according to the configuration of the network device. In this case, the terminal outside the network coverage determines the sidestream configuration according to the pre-configuration information and the information carried in the sidestream broadcast channel PSBCH transmitted by the terminal within the network coverage, and performs sidestream communication.

As shown in fig. 4: for communication outside the network coverage, all terminals performing the sidestream communication are located outside the network coverage range, and all terminals determine sidestream configuration according to the pre-configuration information to perform the sidestream communication.

In one embodiment of the present application, as shown in fig. 5: for sideline communication with a central control node, a plurality of terminals form a communication group, the communication group is provided with the central control node, also called a group head (CH) terminal, and the central control node has one of the following functions: responsible for the establishment of communication groups; adding and leaving of group Member (CM) terminals; performing resource coordination, allocating sideline transmission resources for other terminals, and receiving sideline feedback information of other terminals; and performing resource coordination and other functions with other communication groups. As in fig. 5, terminal UE1 serves as a CH terminal, and UE2 and UE3 serve as CM terminals.

In NR-V2X, unicast, multicast and broadcast transmission modes are supported. For unicast transmission, the receiving end has only one terminal, as shown in fig. 6, unicast transmission is performed between UE1 and UE 2; for multicast transmission, the receiving end is all terminals in a communication group, or all terminals in a certain transmission distance, as in fig. 7, UE1, UE2, UE3, and UE4 form a communication group, where UE1 sends data, and other terminal devices in the group are all terminals of the receiving end; for the broadcast transmission method, the receiving end is any terminal around the sending end terminal, for example, in fig. 8, UE1 is the sending end terminal, and other terminals around it, UE2-UE6 are all terminals of the receiving end.

The following two transmission modes are supported in the sidestream communication. In a first mode: the transmission resource of the terminal is distributed by the network equipment, and the terminal sends data on the side uplink according to the resource distributed by the network equipment; the network device may allocate resources for single transmission to the terminal, and may also allocate resources for semi-static transmission to the terminal. As shown in fig. 2, the terminal is located in the coverage area of the network, and the network allocates transmission resources for sidelink transmission to the terminal. In the second mode: and the terminal selects one resource from the resource pool to transmit data. As shown in fig. 4, the terminal is located outside the coverage area of the cell, and the terminal autonomously selects transmission resources from a pre-configured resource pool to perform sideline transmission; or in fig. 2, the terminal autonomously selects a transmission resource from a resource pool configured by the network for sidelink transmission.

Further, on the basis of the two modes, for a communication group, the CH terminal may also allocate transmission resources for other terminals, for example, allocate transmission resources for other terminals in the communication group in a resource pool configured by the network, or allocate transmission resources for other terminals in the communication group in a resource pool pre-configured by the network.

The method provided by the embodiment of the application is suitable for various scenes, and the following description takes car networking systems, smart home scenes and the like as examples.

For a car networking system: a plurality of vehicles form a communication group; the CH terminal distributes transmission resources for the CM terminals in the group, and when the distance between two communication groups is very close, interference coordination between the two communication groups needs to be considered;

for an in-vehicle communication scenario: a variety of terminal devices, such as speakers, cameras, rear-view mirrors, etc., are included in the vehicle and may be controlled by a central control node in the vehicle. For example, terminals in one vehicle form a communication group or communication system, and different communication groups are used between different vehicles, and when one vehicle moves to the vicinity of another vehicle, interference coordination between the communication groups of the vehicles needs to be considered.

For a home or indoor smart home scene: in a smart home scene, a home or an indoor terminal has a communication function, and the terminals in the home can form a communication group, and the communication group usually has a central control node or a CH terminal, such as a smart phone, a smart television, and a Customer Premises Equipment (CPE); for example, terminals in the same home form a communication group, different communication groups exist among different homes, and the communication group in one home needs to consider interference coordination with communication groups (such as neighbors) in other homes.

In a scenario with multiple communication groups, transmission resources between different communication groups may collide, and interference between communication groups is likely to occur.

The technical concept of the method of the embodiment of the application is as follows: and 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.

The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

The resource coordination method provided by the present application is explained below.

Fig. 9 is a flowchart of an embodiment of a resource coordination method provided in the present application, and as shown in fig. 9, specific implementation steps of the embodiment include:

step 101, the first terminal determines that the second communication group exists.

Wherein the first terminal is a terminal within the first communication group.

In order to fully utilize the system transmission resources, when there is no other second communication group (or the communication groups are far away from each other and the interference is small), one communication group can use all the transmission resources allocated by the network; when a second communication group exists, for example, the second communication group is close to the first communication group, the existence of the second communication group may interfere with communication of terminals of the first communication group, and resource coordination is required. Therefore, it is first necessary to detect whether there are other second communication groups.

In this embodiment, the first terminal is, for example, a head-of-group terminal of the first communication group, and the head-of-group terminal is generally a high-capability-level terminal, such as a terminal having strong signal processing capability and being not limited by power.

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

In this step, the presence of the second communication group may be determined according to a detection result of the first terminal itself on the second communication group, or may be determined according to a detection result of another terminal in the first communication group, which is not limited in this application.

The manner of detecting the second communication group may determine whether the second communication group exists according to a measurement result of a signal or a channel sent by a terminal of the second communication group, or a manner of detecting whether identification information different from the identification information of the first communication group exists, for example, the identification information of the communication group may be carried in some signals or channels, such as a synchronization signal, a broadcast channel, and the like.

And 102, the first terminal performs resource coordination.

When the first terminal determines that other second communication groups exist around the first terminal, resource coordination needs to be carried out so as to avoid or reduce interference between the first communication group and the second communication group.

When performing resource coordination, for example, a terminal in the first communication group may avoid using transmission resources used or reserved by other terminals (for example, a terminal in the current first communication group and terminals in other second communication groups), so as to avoid resource collision with other terminals and reduce interference; for example, it may negotiate with other second communication groups, each using different transmission resources; for example, other second communication groups, transmission resources used by the first communication group, or transmission resources used for transmitting a certain signal or channel may be notified to avoid other second terminals using the transmission resources, to reduce interference, and so on.

In the method of this embodiment, the first terminal determines other second communication groups existing around the current first communication group, performs resource coordination, and reduces resource conflicts, thereby reducing interference between the first communication group and the second communication group.

In one embodiment, how to determine the existence of the second communication group can be achieved in various ways, and several possible implementations are described in detail below:

an implementation a:

and the first terminal determines that the second communication group exists according to the detection result of the first terminal.

In this method, the first terminal itself detects the presence of the second communication group, and determines the presence of the second communication group based on the detection result of the first terminal.

For the first terminal to determine the existence of the second communication group according to the detection result of the first terminal, the following several ways are adopted:

mode a:

if the detection result of the first terminal comprises: and the first terminal determines that a second communication group exists, wherein the second identification information is different from the first identification information of the first communication group.

Specifically, different communication groups may have different Identification (ID) information, which may be carried in some signals or channels transmitted by the terminal. Therefore, whether the second communication group exists can be determined by detecting the identification information, and if the second identification information different from the first identification information of the first communication group exists is detected, the second communication group exists.

In an embodiment, the first terminal detects a synchronization signal or a broadcast channel to obtain the second identification information.

In an embodiment, for the same communication group, in order to maintain synchronization between terminals in the group, a group head terminal (or a central control node) usually sends a synchronization signal, where the synchronization signal carries identification information of the communication group, and synchronization signals sent by group head terminals of different communication groups correspond to different identification information.

For example, when the first terminal detects an ID different from that of the first communication group, it may be judged that the second communication group exists.

In an embodiment, it is also possible to detect a broadcast channel and determine whether the second communication group exists according to ID information in the broadcast channel.

For example, as shown in fig. 10, CH1, UE1, and UE2 are first communication groups, CH2, UE3, and UE4 are second communication groups, CH1 and CH2 transmit Synchronization signals, and correspond to Synchronization Signal Identification (SSID) 1 and SSID 2, respectively, CH1 detects the Synchronization Signal transmitted by CH2 and determines that the corresponding identification information is SSID 2, and the Synchronization Signal transmitted by CH1 has different identification information, that is, it can be determined that there is a second communication group.

In fig. 10, the first communication group and the second communication group may be asynchronous, and when the central control node CH1 of the first communication group receives uplink signals sent by other terminals of the first communication group, the time may correspond to downlink transmission of the second communication group, so that the central control node CH1 may receive a synchronization signal sent by the central control node CH2 of the second communication group. Or, 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 certain time slot is used for uplink transmission for the first communication group, but may be used for downlink transmission for the second communication group, so that CH1 may receive the synchronization signal sent by the central control node CH2 of the second communication group.

In an embodiment, the second identification information comprises at least one of the following information: radio Network Temporary Identity (RNTI), communication group Identity information, synchronization Signal Identity SSID, or Sidelink Synchronization Signal Identity (SLSS ID).

In the foregoing specific embodiment, by detecting the identification information, other second communication groups existing around the first communication group can be identified, the operation is simple, and further, resource coordination can be performed to reduce interference between the first communication group and the second communication group.

Mode b:

a first terminal measures a signal or a channel sent by a second terminal;

and if the detection result comprises that the measurement result of the first terminal on the signal or the channel from the second terminal exceeds a first threshold, the first terminal determines that the second communication group exists, wherein the second terminal is a terminal in the second communication group.

Specifically, a first terminal in a first communication group may receive signals or channels of other communication groups, perform measurements on the signals or channels of the other communication groups, and determine that a second communication group exists when the measurement result exceeds a first threshold. When the measurement result is smaller than the first threshold, it may be considered that the other communication groups are far away, and resource coordination may not be required.

Wherein exceeding the threshold means being greater than or equal to the first threshold.

In an embodiment, the first threshold is preconfigured, network side configured or first terminal configured.

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 application.

In an embodiment, the measurements comprise measurements of at least one of the following signals: a synchronization Signal, a Demodulation Reference Signal (DMRS), a Channel State Information measurement Reference Signal (CSI-RS), or a Sounding Reference Signal (SRS); or, the measurement result comprises a measurement result of at least one of the following channels: a Physical Sidelink Broadcast Channel (PSBCH), a Physical Sidelink Shared Channel (psch), a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Feedback Channel (PSFCH), a Physical Broadcast Channel (PBCH), a Physical Downlink Shared Channel (PDSCH), a Physical Uplink Shared Channel (PUSCH), a Physical Downlink Control Channel (PDCCH), or a Physical Uplink Control Channel (PUCCH).

In an embodiment, the synchronization signal may include at least one of the following signals: primary Synchronization Signal (PSS), secondary Synchronization Signal (SSS), lateral Primary Synchronization Signal (S-PSS), and lateral Secondary Synchronization Signal (S-SSS).

In an embodiment, the DMRS comprises one of: PDSCH DMRS, PDCCH DMRS, PBCH DMRS, PUSCH DMRS, PUCCH DMRS, PSSCH DMRS, PSCCH DMRS, and PSBCH DMRS.

It should be understood that the signal or channel in this embodiment may be any signal or channel transmitted between the group head and the group member, or between the group member and the group member, and the present invention is not limited thereto.

In an embodiment, the measurement results include at least one of: RSRP, RSRQ, SINR, RSSI. For example, if the measurement result is a measurement result of a signal, the measurement result includes at least one of: a Reference Signal Received Power (RSRP) or a Reference Signal Received Quality (RSRQ); if the measurement result is a measurement result of a channel, the measurement result includes at least one of the following: the signal to noise ratio SINR or the received signal field strength indicates RSSI.

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

For example, for a communication group consisting of vehicles, data transmission is performed between terminals in the communication group through a sidelink, so that a first terminal in a first communication group can measure a sidelink signal or a sidelink channel of another communication group and further determine whether a second communication group exists.

For example, in the scenario of in-vehicle communication, the communication between the central control node and the other in-vehicle terminals is usually performed through uplink and downlink channels (PDSCH, PDCCH, PUSCH, PUCCH), and therefore, the first terminal may measure uplink and downlink channels or signals transmitted by another in-vehicle terminal or terminals of another communication group, and further determine whether or not the second communication group exists. In an in-vehicle scene, since communication groups of different vehicles may be asynchronous, when a central control node of a first communication group receives an uplink channel sent by other terminals of the communication group, the time may correspond to downlink transmission of another communication group, and thus the central control node may receive a downlink channel and a downlink signal sent by a central control node of another communication group.

In the foregoing embodiment, through the measurement result of the signal or the channel, other second communication groups existing around the first communication group can be identified, and resource coordination can be further performed to reduce interference between the first communication group and the second communication group.

In the two modes, the first terminal determines other second communication groups existing around the first communication group according to the detection result of the first terminal.

Another implementation mode B:

the first terminal acquires first indication information;

the first terminal determines that a second communication group exists according to the first indication information; wherein the first indication information is used for indicating that the second communication group exists.

In an embodiment, the obtaining, by the first terminal, the first indication information includes:

the first terminal receives first indication information sent by a third terminal, wherein the third terminal is a terminal in the first communication group.

Wherein the third terminal may be any one of the group member terminals in the first communication group.

Specifically, the first terminal may determine that the second communication group exists according to the first indication information of other third terminals in the first communication group. The first indication information indicates that the second communication group exists, and the second indication information may include information of the second communication group, such as identification information of the second communication group, information of terminals within the second communication group, and the like.

For the way that the third terminal detects the second communication group, reference may be made to the way that the first terminal detects the second communication group in the foregoing embodiment, for example, the way a and the way b, which are not described herein again.

For example, as shown in fig. 11, CH1, UE1, and UE2 are the first communication group, CH2, UE3, and UE4 are the second communication group, CH1 and CH2 transmit synchronization signals, SSID 1 and SSID 2 correspond to the synchronization signals detected by CH2, respectively, and UE2 determines that the corresponding identification information is SSID 2, and the identification information is different from the synchronization signal transmitted by CH1, i.e., it can determine that the second communication group exists.

Optionally, the first indication information is carried in sidelink control information SCI, a media access control unit MAC CE of data, or a radio resource control PC5-RRC signaling; or the like, or, alternatively,

the first indication information is carried in a Physical Uplink Control Channel (PUCCH); or the like, or, alternatively,

the first indication information is carried in a physical uplink control channel (PUSCH).

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

In an embodiment, the third terminal is a terminal configured for the first terminal to detect the second communication group, or the third terminal is a terminal in the first communication group whose measurement result on the signal or channel from the first terminal is less than or equal to the second threshold.

The third terminal may be a terminal configured by the first terminal and configured to detect the existence of the second communication group, or may be any group member terminal in the first communication group that detects the existence of the second communication group according to a measurement result, for example, if the measurement result of the signal or channel of the first terminal is less than or equal to the second threshold, the terminal serves as the third terminal and detects the existence of the second communication group.

In an embodiment, the second threshold is preconfigured, network side configured or first terminal configured.

For example, when a third terminal measures RSRP of the first terminal below a second threshold, the third terminal may be considered to be far away from the first terminal or located at an edge position of the first communication group, and such a terminal may more easily detect whether there are other communication groups around, and thus detect the presence of the second communication group by the third terminal.

In an embodiment, the first terminal is configured to detect resources of the second communication group. For example, resources for detecting identification information or resources for performing measurements on signals or channels transmitted by terminals of the second communication group. The resources may include time domain resources and/or frequency domain resources.

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 the signals or channels transmitted by the terminals of the second communication group within the time window;

for another example, the first terminal configures a pattern (pattern) for detecting the second communication group for the first terminal or the third terminal, and according to the pattern, time domain and/or frequency domain resources for detecting the second communication group can be determined. Wherein, the corresponding time frequency resource can be determined according to the detection pattern.

In the above specific embodiment, the first terminal determines, according to the detection result of the other third terminal, the other second communication groups existing around the first communication group, and may further perform resource coordination, so as to reduce interference between the first communication group and the second communication group.

In an embodiment, before performing resource coordination, the first terminal needs to confirm whether to perform resource coordination, for example, perform resource coordination when certain conditions are met. For example, when two communication groups are relatively far away, interference is low, and resource coordination is not needed; when the two communication groups are close to each other and the interference is strong, the interference coordination is needed.

In an embodiment, for a case where the first terminal detects the existence of the second communication group by itself (i.e. implementation a), if a measurement result of the first terminal on a signal or a channel from the second terminal exceeds a third threshold, the first terminal performs resource coordination.

Specifically, in this manner, only when the measurement result of the first terminal on the signal or the channel from the second terminal satisfies a preset condition, the first terminal needs to be triggered to perform interference coordination, for example, the measurement result of the first terminal on the signal or the channel sent by the second terminal exceeds a third threshold, and the first terminal performs resource coordination. For example, when the measurement result does not exceed the third threshold, it indicates that the interference of the second communication group to the second communication group is small, and the resource coordination may not be performed.

In another embodiment, for the case that the first terminal determines that the second communication group exists according to the detection result of the other third terminal (i.e. implementation B), the method further includes:

the first terminal receives second indication information of a fourth terminal of the first communication group; the second indication information is used for the first terminal to determine resource coordination.

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.

In an embodiment, the second indication information is sent by the fourth terminal when the measurement result of the second communication group exceeds the sixth threshold. If the interference is smaller than the sixth threshold, the report is not needed.

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

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 application.

In an embodiment, the second indication information is used to indicate the first terminal to perform resource coordination; or the like, or, alternatively,

the second indication information is used for indicating that the measurement result of the fourth terminal on the terminals in the second communication group exceeds a fourth threshold; or the like, or, alternatively,

the second indication information includes a measurement result of the fourth terminal on the terminals in the second communication group.

Specifically, the second indication information may directly indicate the first terminal to perform resource coordination, and the first terminal does not need to perform judgment any more. Or, the second indication information may indicate that the measurement result exceeds the fourth threshold, the first terminal may determine to perform resource coordination. Wherein the fourth threshold and the sixth threshold may be the same or different.

Or the second indication information includes a measurement result of the fourth terminal on the terminal in the second communication group, and the first terminal determines whether to perform resource coordination according to the measurement result of the fourth terminal on the terminal in the second communication group.

In an embodiment, if the measurement result exceeds the fifth threshold, the first terminal performs resource coordination. Wherein the fifth threshold and the sixth threshold may be the same or different.

In an embodiment, the second indication information is carried in the sidelink Control information SCI, a media access Control Element (MAC CE) of data, or a Radio Resource Control (PC 5 Radio Resource Control, PC 5-RRC) signaling; or the like, or, alternatively,

the second indication information is carried in a Physical Uplink Control Channel (PUCCH); or the like, or, alternatively,

and the second indication information is carried in a physical uplink control channel (PUSCH).

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

Wherein, any one of the third threshold to the sixth threshold may be preconfigured, configured by the network side or configured by the first terminal.

In the above specific embodiment, before performing resource coordination, whether to perform resource coordination is determined, and resource coordination may not be performed under the condition of small interference, thereby simplifying the operation of the first terminal and saving power consumption.

In an embodiment, resource coordination for the first terminal may be implemented in various manners, for example, in the following manners:

one implementation 1-1:

and the first terminal sends third indication information to the terminals in the first communication group, wherein the third indication information is used for indicating the terminals in the first communication group to autonomously select transmission resources.

Specifically, usually, the group head terminal may allocate resources to the group member terminals in the communication group, or the transmission resources of the group member terminals are allocated on the network side, and to avoid interference between the terminals, the first terminal may instruct the terminals in the first communication group to autonomously select the transmission resources.

The terminals in the first communication group may also include the third terminal and the fourth terminal in the foregoing embodiments.

When the group head terminal allocates transmission resources for the group member terminals in the communication group, the group member terminals are not required to perform interception generally, and only the resources allocated at the group head terminal are required to perform data transmission. In an embodiment, when a group member terminal in a communication group autonomously selects a transmission resource, the group member terminal in the communication group generally needs to acquire the transmission resource in an interception manner, and during an interception process, the terminal may avoid selecting the transmission resource that has been used or reserved by other terminals (including the terminal in the communication group and terminals in other communication groups), so that resource conflict with the terminals in other communication groups may be avoided, and interference is reduced.

In the foregoing specific embodiment, the terminal in the first communication group autonomously selects the transmission resource, so that it is possible to avoid selecting the transmission resource that has been used or reserved by other terminals (including the terminal in the present communication group and the terminals in other communication groups), and therefore, resource collision with the terminals in other communication groups can be avoided, and interference is reduced.

In an embodiment, the third indication information is carried in the sidelink Control information SCI, a media access Control Element (MAC CE) of the data, or a Radio Resource Control (PC 5 Radio Resource Control, PC 5-RRC) signaling; or the like, or, alternatively,

the third indication information is carried in a Physical Downlink Control Channel (PDCCH); or the like, or a combination thereof,

the third indication information is carried in a physical uplink control channel (PDSCH).

One implementation 1-2:

and the first terminal sends fourth indication information to the terminals in the first communication group, wherein the fourth indication information is used for indicating to activate the autonomous listening mode of the terminals in the first communication group.

Specifically, usually, the group head terminal may 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, and at this time, the group member terminals do not need to perform interception. In order to avoid interference between terminals, the first terminal may send, to the terminals in the first communication group, indication information, where the indication information is used to indicate that an autonomous listening mode of the terminal is activated or indicate that a listening function is activated, and after the autonomous listening mode is activated, the terminals in the first communication group may avoid, through listening, selecting a transmission resource that has been used or reserved by other terminals (including the terminals in the communication group and the terminals in other communication groups), so that resource collision between the terminals in other communication groups may be avoided, and interference may be reduced.

In the foregoing specific embodiment, the terminal in the first communication group may avoid selecting the transmission resource that has been used or reserved by another terminal (including the terminal in the present communication group and the terminal in another communication group), so that resource collision with the terminal in another communication group may be avoided, and interference may be reduced.

In an embodiment, the fourth indication information is carried in the sidelink Control information SCI, a media access Control Element (MAC CE) of data, or a Radio Resource Control (PC 5 Radio Resource Control, PC 5-RRC) signaling; or the like, or, alternatively,

the fourth indication information is carried in a Physical Downlink Control Channel (PDCCH); or the like, or, alternatively,

the fourth indication information is carried in a physical uplink control channel PDSCH.

One implementation 1-3:

the first terminal receives available resource information and/or unavailable resource information sent by terminals in a first communication group;

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

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.

Specifically, the terminals in the first communication group may determine which resources are available resources or unavailable resources (i.e., transmission resources with strong interference) through listening, and the terminals in the first communication group may report available resource information and/or unavailable resource information to the first terminal, for example, the available resource information and/or unavailable resource information may be delivered to the first terminal in a resource set manner.

The available resource information and/or the unavailable resource information may assist the first terminal in scheduling resources, for example, the first terminal allocates transmission resources to terminals in the first communication group in the available resource set, or avoids allocating transmission resources in the unavailable resource set to terminals in the first communication group, thereby achieving the purpose of avoiding or reducing interference between communication groups.

In the foregoing specific embodiment, the terminals in the first communication group may send the available resource information and/or the unavailable resource information to the first terminal in an interception manner, and the first terminal allocates resources to the terminals in the first communication group according to the available resource information and/or the unavailable resource information, so as to avoid 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.

One implementation 1-4:

the first terminal allocates resources for a first communication group and a second communication group, wherein the resources of the first communication group and the resources of the second communication group are different in time domain and/or frequency domain;

and the first terminal sends the resource information of the second communication group to the terminals of the second communication group.

Specifically, when there is no other communication group in the surroundings, the first communication group may use all transmission resources allocated by the network to increase the transmission rate, but when there is another communication group in the surroundings, different transmission resources may be used between the communication groups, for example, orthogonal transmission resources may be used to reduce interference between the communication groups.

For example, the communication groups multiplex transmission resources in a time division and/or frequency division manner, for example, the bandwidth of the system is 20mhz, and when two communication groups need resource coordination, each communication group can respectively use the bandwidth of 10 mhz for data transmission, thereby avoiding interference.

Time division multiplexing refers to different communication groups transmitting using different time resources;

frequency division multiplexing refers to different communication groups transmitting using different frequency domain resources.

In an 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, so as to reduce interference between the first communication group and the second communication group.

The first terminal may send the resource information of the second communication group to a group head terminal or a group member terminal of the second communication group, which is not limited in this embodiment of the present application.

In an embodiment, for example, a head-of-group terminal in the second communication group may perform resource coordination according to resource information of the second communication group allocated by the first terminal, and allocate resources to group member terminals in the second communication group, so as to reduce interference between the first communication group and the second communication group.

In an embodiment, the resources of the first communication group and the second communication group are resources using different channels; or the like, or, alternatively,

the resources of the first communication group and the second communication group are resources using different sub-bands; the sub-band comprises at least one physical resource block, PRB; or the like, or a combination thereof,

the resources of the first communication group and the second communication group are resources using different comb PRBs, and the comb PRBs comprise M discontinuous PRBs in a frequency domain; m is an integer greater than 0.

For example, in unlicensed spectrum, one channel corresponds to a 20MHz bandwidth, the transmission resource may include multiple channels, and different communication groups may use different channels when coordinating resources among the communication groups.

For example, one subband may include multiple PRBs, and in sidelink communications, the frequency domain resources may be divided into multiple subbands, each subband including N PRBs (e.g., N =5, 10, 15, 20, 50, 100, etc.), and when resource coordination is performed between multiple communication groups, different communication groups may use different subbands for data transmission.

For comb PRB (Interlace PRB): the comb PRB includes M PRBs non-contiguous in the frequency domain, one comb PRB pattern is formed by one PRB out of every K PRBs, for example, 15kHz subcarrier spacing for a bandwidth of 20MHz, the system bandwidth includes 100 PRBs, if K =10, i.e., one PRB out of every 10 PRBs forms one comb PRB pattern, for example, PRB 0,10, 20, 30, 40, 50, 60, 70, 80, 90 is one comb PRB pattern, PRB 1, 11, 21, 31, 41, 51, 61, 71, 81, 91 is another comb PRB pattern, and so on, the system includes 10 comb PRB patterns in total, and when two communication groups are resource coordinated, different communication groups may use different comb PRB patterns, for example, a first communication group uses first to fifth comb PRB patterns, and a second communication group uses sixth to tenth comb PRB patterns.

In the foregoing specific embodiment, the first terminal allocates resources to the first communication group and the second communication group, and the terminals in the second communication group perform communication according to the resources allocated to the terminals by the first terminal, so that the purpose of avoiding or reducing interference between the communication groups is achieved because the resources of the first communication group and the resources of the second communication group are different in the time domain and/or the frequency domain.

Implementation mode 1-5

channel information used by terminals within the first communication group;

resource pool configuration information for the first communication group;

semi-static transmission resource information of terminals in a first communication group;

load indicator (OI) information;

high Interference Indicator (HII) information; or the like, or, alternatively,

a first set of transmission resources of a first communication group.

Specifically, the first communication group may send fifth indication information to the terminals in the second communication group, where the fifth indication information includes resource usage of the terminals in the first communication group, for example, so as to avoid the terminals in the second communication group from using the resources of the first communication group. Such as channel information used by terminals within the first communication group, resource pool configuration information for the first communication group, semi-static transmission resource information for terminals within the first communication group, and so forth.

For example, the first terminal may also send OI information and/or HII information to terminals in the second communication group, indicating the interference situation of the first communication group.

In an embodiment, the first communication group may exchange, to the terminals in the second communication group, the more important transmission resources of the first communication group, which are usually the resources that are not desired to be interfered by other terminals, for example, the high priority transmission resources, and send the more important transmission resources to the terminals in the second communication group through the first set of transmission resources, so that the terminals in the second communication group do not use the more important transmission resources, thereby reducing interference.

In an embodiment, the terminals in the second communication group may coordinate resources in the second communication group according to the received fifth indication information, so as to avoid or reduce the use of transmission resources used by the terminals in the first communication group, thereby reducing interference, where the fifth indication information is, for example, channel information used to indicate the use of the terminals in the first communication group, or the first transmission resource set of the first communication group.

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 this application.

In an embodiment, the resources in the first set of transmission resources are used for transmitting one or more of the following signals: sounding Reference Signal (SRS), channel State Information measurement Reference Signal (CSI-RS), system Information Block (SIB), control Information, resource scheduling Information, and high Reliability Low Latency Communication (URLLC) data. The first terminal of the first communication group sends the transmission resource set to the terminal of the second communication group, and the terminal of the second communication group avoids using the transmission resource of the transmission resource set, so that the interference to the first communication group can be reduced.

In an embodiment, the fifth indication information is carried in at least one of the following signaling:

broadcast channel signaling, sidelink control information SCI, medium access control element MAC CE, radio resource control PC5-RRC signaling.

In the above specific embodiment, the first terminal sends the resource usage of the first communication group to the terminals in the second communication group, and the terminals in the second communication group may perform resource coordination according to the resource usage of the first communication group, thereby achieving the purpose of avoiding or reducing interference between the communication groups.

The following gives a specific example of the resource coordination process between communication groups:

example 1: as shown in fig. 12, UE1 is a terminal of communication group 1, CH1 is a head terminal of communication group 1, UE3 is a terminal of communication group 2, and CH2 is a head terminal of communication group 2; CH1 distributes transmission resources for UE1, CH2 distributes transmission resources for UE3, when two communication groups are far apart, two communication groups can use network to distribute all transmission resources; when two communication groups are close to each other, the terminal UE1 in the communication group 1 may detect the existence of the communication group 2, for example, by detecting a synchronization signal, if the result of measuring the signal or channel transmitted by the CH by the UE1 exceeds a threshold, the terminal UE1 may transmit indication information to the CH1 to notify that there are other communication groups around the CH1, and resource coordination may be performed between the CH1 and the CH2, for example, transmission resources are used in a frequency division multiplexing manner, that is, each communication group uses half of frequency domain resources, and terminals in the groups are scheduled in the respective communication groups, respectively.

Example 2: as shown in fig. 13, similar to example 1, example 2 is different from example 1 in that a resource coordination method is used, and when CH1 receives indication information reported by UE1 and determines that other communication groups exist around the terminal, CH1 may modify a resource allocation manner of the terminal in the group, and change from a group head terminal allocating transmission resources to a terminal autonomously selecting transmission resources; in the process that the terminal autonomously selects the transmission resources, the terminal acquires the transmission resources in an interception mode, and the transmission resources which are used or reserved by other terminals can be prevented from being selected in the interception process, so that the interference between the terminals in the two communication groups can be realized.
