Detailed ways

The method and device provided in the embodiments of the present application can be applied to a communication system. Figure 1 shows a schematic diagram of the structure of a communication system. The communication system 100 includes one or more network devices (the network device 110 and the network device 120 are shown in the figure), and one or more terminals that communicate with the one or more network devices. The terminal 114 and the terminal 118 shown in FIG. 1 communicate with the network device 110, and the terminal 124 and the terminal 128 shown in FIG. 1 communicate with the network device 120. It can be understood that network devices and terminals may also be referred to as communication devices.

Techniques described embodiment of the present invention may be used for various communication systems such as communication fourth generation (4 ^th generation, 4G) communication system, a communication system, 4.5G, 5G communication system, a variety of communication systems integration system, or future evolution system. For example, long-term evolution (LTE) system, new radio (NR) system, wireless-fidelity (WiFi) system, and 3rd generation partnership project (3GPP) related Communication systems, etc., as well as other such communication systems.

Figure 2 shows a schematic diagram of an example of a possible architecture of a communication system. As shown in Figure 2, the network equipment in the radio access network (RAN) is a centralized unit (CU) and a distributed unit (distributed unit). unit, DU) A base station with a separate architecture (such as gNodeB or gNB). The RAN can be connected to a core network (for example, it can be an LTE core network, or a 5G core network, etc.). CU and DU can be understood as the division of base stations from the perspective of logical functions. CU and DU can be physically separated or deployed together. Multiple DUs can share one CU. One DU can also be connected to multiple CUs (not shown in the figure). The CU and the DU can be connected through an interface, for example, an F1 interface. CU and DU can be divided according to the protocol layer of the wireless network. For example, the functions of the packet data convergence protocol (PDCP) layer and the radio resource control (radio resource control, RRC) layer are set in the CU, while the radio link control (RLC) and media access control The functions of the (media access control, MAC) layer and the physical layer are set in the DU. It can be understood that the division of CU and DU processing functions according to this protocol layer is only an example, and it can also be divided in other ways. For example, the CU or DU can be divided into functions with more protocol layers. For example, the CU or DU can also be divided into part of the processing functions with the protocol layer. In a design, part of the functions of the RLC layer and the functions of the protocol layer above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layer below the RLC layer are set in the DU. In another design, the functions of the CU or DU can also be divided according to service types or other system requirements. For example, it is divided by time delay, and functions whose processing time needs to meet the delay requirement are set in the DU, and functions that do not need to meet the delay requirement are set in the CU. The network architecture shown in FIG. 2 can be applied to a 5G communication system, and it can also share one or more components or resources with an LTE system. In another design, the CU may also have one or more functions of the core network. One or more CUs can be set centrally or separately. For example, the CU can be set on the network side to facilitate centralized management. The DU can have multiple radio frequency functions, or the radio frequency functions can be set remotely.

The function of the CU can be implemented by one entity, or the control plane (CP) and the user plane (UP) can be further separated, that is, the control plane (CU-CP) and the user plane (CU-UP) of the CU can have different functions It is realized by an entity, and the CU-CP and CU-UP can be coupled with the DU to jointly complete the function of the base station.

It is understandable that the embodiments provided in this application are also applicable to an architecture where the CU and DU are not separated.

The base station can contain one or more co-site or non-co-site TRPs. The network device may also be a wireless controller, CU, and/or DU in a cloud radio access network (CRAN) scenario. The network device can also be a server, a wearable device, a machine communication device, or a vehicle-mounted device, etc. The following description takes the network device as a base station as an example. The multiple network devices may be base stations of the same type, or base stations of different types. The base station can communicate with the terminal equipment, and can also communicate with the terminal equipment through the relay station. The terminal device can communicate with multiple base stations of different technologies. For example, the terminal device can communicate with a base station that supports an LTE network, can also communicate with a base station that supports a 5G network, and can also support communication with a base station of an LTE network and a base station of a 5G network. Double connection.

A terminal is a device with wireless transceiver function, which can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; it can also be deployed on the water (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons, etc.) And satellite class).

Wait.

In a wireless communication network, a terminal can use another terminal to forward data to a network device. This method can also be called terminal cooperation. However, when the network device controls the data transmission of the two terminals, a signaling storm will be generated, which in turn increases the communication overhead. For example, a network device needs to send signaling for data scheduling for two terminals respectively. When a terminal sends data to another terminal, it also needs to send signaling for data scheduling to the other terminal. When the terminals participating in the terminal cooperation As the number increases, the amount of signaling required will increase accordingly. Therefore, how to reduce the cost of terminal cooperative communication has become a problem that needs to be solved urgently.

In the embodiment provided in this application, a joint scheduling method is designed. In the method, the side link between the terminals and the uplink between the terminal and the network device are controlled through a kind of joint scheduling control information, so as to reduce the terminal coordination. Signaling overhead during communication.

For example, the time domain resource included in the physical resource may include at least one frame, at least one sub-frame, at least one slot, at least one mini-slot, and at least one time unit. , Or at least one time domain symbol, etc. For example, the frequency domain resources included in the physical resource may include at least one carrier (carrier), at least one component carrier (CC), at least one bandwidth part (BWP), and at least one resource block group (resource block group). block group, RBG), at least one physical resource-block group (PRG), at least one resource block (resource block, RB), or at least one sub-carrier (sub-carrier, SC), etc. For example, the airspace resources included in the physical resources may include at least one beam, at least one port, at least one antenna port, or at least one layer/space layer, or the like. For example, the code domain resources included in the physical resources may include at least one orthogonal cover code (OCC), or at least one non-orthogonal multiple access (NOMA) code, and so on.

The technical solution of the present application will be described in detail below with specific embodiments in combination with the drawings. The following embodiments and implementation manners can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. It should be understood that the functions explained in this application can be implemented by independent hardware circuits, using software running in combination with a processor/microprocessor or general-purpose computer, using application specific integrated circuits, and/or using one or more digital signal processors. achieve. When this application is described as a method, it can also be implemented in a computer processor and a memory coupled to the processor.

To make it easier to understand the embodiments in this application, some concepts or terms involved in this application are first briefly described.

Downlink (DL): The link from the network device to the terminal.

Uplink (uplink, UL): The link from the terminal to the network device.

Sidelink (SL): A link from one terminal to another one or more terminals. It can also be called side link, side link, device to device (D2D) link, vehicle to everything (V2X) link, or vehicle to vehicle (V2V) link.

Terminal grouping: It can also be called terminal clustering, terminal grouping, or terminal clustering. Two or more terminals form a terminal group (also called a terminal cluster, a terminal cooperation group, or a terminal cluster, etc.). The terminal group contains a cooperative terminal (also called a cluster head terminal, a cluster agent terminal, etc.). Or a cooperative user equipment (cooperating UE, CUE), etc.) and one or more target terminals (also referred to as a cluster member terminal, a cluster common terminal, or a target user equipment (target UE, TUE)). The terminals in the terminal group can communicate with network devices in a manner of terminal cooperation.

CUE: The UE in the terminal group that directly communicates with the network equipment, and can assist the TUE in the terminal group to communicate with the network equipment.

TUE: A UE in a terminal group that uses CUE to communicate with network equipment.

Take Figure 3 as an example to further illustrate terminal grouping, CUE and TUE. Fig. 3 shows a schematic diagram of a communication scenario 300. The communication scenario 300 illustrated in FIG. 3 includes a network device 310, a terminal 320, and a terminal 330. The terminal 320 and the terminal 330 form a terminal group 340, the terminal 320 is a CUE in the terminal group 340, and the terminal 330 is a TUE in the terminal group 330. The terminal 320 CUE can directly communicate with the network device 310, and the terminal 330 TUE communicates with the network device 310 through the terminal 320. It can be understood that FIG. 3 only takes one terminal group and one TUE included in the terminal group as an example for schematic illustration, and this application does not limit the number of terminal groups and the number of TUEs in the terminal group.

The terminal group communication (or called terminal cooperative communication) scenario illustrated in FIG. 3 can adapt to certain communication requirements. For example, when the terminal 330 TUE is an energy-sensitive terminal, and the terminal 320 CUE is an energy-insensitive terminal, the terminal 320 CUE and the terminal 330 TUE can form a terminal group 340, and the terminal 330 TUE passes through the terminal 320 CUE and the network device 310 To communicate. Since the terminal 320 CUE and the terminal 330 TUE in the terminal group 340 are generally close, the energy consumption of the terminal 330 TUE when communicating with the terminal 320 CUE is low, thereby prolonging the service life of the energy-sensitive terminal 330 TUE.

FIG. 4 is a schematic diagram of interaction of a communication method 400 provided by an embodiment of this application. In FIG. 4, the first terminal, the second terminal, and the network device are taken as an example of the execution body of the interaction signal to illustrate the communication method, but the present application does not limit the execution body of the interaction signal. For example, the network device in FIG. 4 may also be a chip, a chip system, or a processor that supports the network device to implement the method. For example, the first terminal in FIG. 4 may also be a chip, a chip system, or a processor that supports the first terminal to implement the method. For example, the second terminal in FIG. 4 may also be a chip, a chip system, or a processor that supports the second terminal to implement the method. As shown in FIG. 4, the method 400 of this embodiment may include a part 410, a part 420, and a part 430:

Part 410: The network device sends control information, and the first terminal and the second terminal receive the control information. Optionally, the network device sends the control information in a multicast manner. Optionally, the first terminal and the second terminal belong to the same terminal group. Further optionally, the first terminal is a TUE, and the second terminal is a CUE. For the description of the terminal group, TUE and CUE, refer to the description of the terminal group, TUE and CUE in FIG. 3. Optionally, the first terminal is an energy consumption sensitive terminal, and the second terminal is an energy insensitive terminal. The control information can be understood as a kind of joint scheduling control information, which can be used to schedule side link data between the first terminal and the second terminal, and can also be used to schedule the uplink between the second terminal and the network device. Road data.

Part 420: The first terminal sends data on the first resource according to the above control information, and the second terminal receives the data from the first terminal on the first resource according to the above control information. Optionally, the first terminal transmits the above-mentioned data on the sidelink channel, and the second terminal receives the data on the sidelink channel. The sidelink channel may be, for example, a physical sidelink shared channel (PSSCH). ), or physical sidelink discovery channel (PSDCH), etc.

Part 430: The second terminal sends the above data on the second resource according to the above control information, and the network device receives the data from the second terminal on the second resource. Optionally, the second terminal sends the above-mentioned data on the uplink channel, and the network device receives the data on the uplink channel. The uplink channel may be, for example, a physical uplink shared channel (PUSCH). In part 430, the second terminal sends the above-mentioned data according to the above-mentioned control information. It can be understood that the second terminal forwards the above-mentioned data from the first terminal to the network device according to the above-mentioned control information.

Through the above method, the network device can complete the joint scheduling of the side link and the uplink in the terminal coordinated communication through a piece of control information, so that the signaling overhead during the terminal coordinated communication can be reduced.

Optionally, the control information in the method 400 is carried in a physical channel, and the physical channel may be, for example, a physical downlink control channel (PDCCH) or the like. The control information can be transmitted more quickly through the physical channel, which can reduce the time delay in the terminal cooperative communication process.

Optionally, the control information in the method 400 is scrambled by one of the following radio network temporary identifiers (RNTI):

Group RNTI: This group of RNTI is used to identify a terminal group. For example, the group RNTI identifier may be used to identify a terminal group including the first terminal and the second terminal. The group of RNTI may be configured by the network device for the first terminal and/or the second terminal, may also be determined by the second terminal and notified to the first terminal, or determined by the first terminal and notified to the second terminal. In part 410, the first terminal and/or the second terminal may use the set of RNTI to descramble the control information when receiving the control information, and then further execute part 420 and/or part 430. For example, after the first terminal successfully descrambles the control information using the group of RNTIs, it can learn that the control information is used for joint scheduling, and send the above-mentioned data to the second terminal through the side link. For another example, after the second terminal successfully descrambles the control information using the group of RNTIs, it can learn that the control information is used for joint scheduling, and receive the above-mentioned data from the first terminal and forward the data to the network device.

Cell RNTI (cell RNTI, C-RNTI) of the first terminal: The C-RNTI of the first terminal is used to identify the first terminal. The first terminal may notify the second terminal of the C-RNTI of the first terminal through the side link, or the network device may notify the second terminal of the C-RNTI of the first terminal through the downlink. In part 410, the first terminal and/or the second terminal may use the C-RNTI of the first terminal to descramble the control information when receiving the control information, and then further execute part 420 and/or part 430. For example, when the first terminal does not initiate an uplink scheduling request, after the first terminal uses the C-RNTI of the first terminal to successfully descramble the control information, it can learn that the control information is used for joint scheduling, and send the control information to the first terminal through the side link. The second terminal sends the above-mentioned data. For another example, after the second terminal successfully descrambles the control information using the C-RNTI of the first terminal, it can learn that the control information is used for joint scheduling, and receive the above-mentioned data from the first terminal and forward the data to the network device.

C-RNTI of the second terminal: The C-RNTI of the second terminal is used to identify the second terminal. The second terminal may notify the first terminal of the C-RNTI of the second terminal through the side link, or the network device may notify the first terminal of the C-RNTI of the second terminal through the downlink. In part 410, the first terminal and/or the second terminal may use the C-RNTI of the second terminal to descramble the control information when receiving the control information, and then further execute part 420 and/or part 430. For example, after the first terminal successfully descrambles the control information using the C-RNTI of the second terminal, it can learn that the control information is used for joint scheduling, and send the above-mentioned data to the second terminal through the side link. For another example, when the second terminal does not initiate an uplink scheduling request, after the second terminal uses the C-RNTI of the second terminal to successfully descramble the control information, it can learn that the control information is used for joint scheduling and receive the control information from the first terminal. And forward the data to the network device.

The control information is scrambled through the above RNTI, so that the terminal can correctly recognize the control information.

In part 420, optionally, the first terminal sends data to the second terminal in an authorization-free manner on the first resource according to the above-mentioned control information. In part 420, optionally, the second terminal receives the above-mentioned data from the first terminal in an authorization-free manner on the first resource according to the above-mentioned control information. In part 430, optionally, the second terminal sends the above-mentioned data to the network device in an authorization-free manner on the second resource according to the above-mentioned control information. Through this method, the side link and/or uplink unlicensed communication can be activated through a piece of control information, so that the process of unlicensed communication can be simplified and the communication delay can be reduced.

The control information in the method 400 may have multiple possible implementation manners. The first terminal may obtain the first resource through the control information, and the second terminal may obtain the first resource and the second resource through the control information. A possible implementation manner of the control information will be described below with reference to the examples in FIGS. 5A to 5F.

● Time domain offset and frequency domain offset between R2 and R1.

In a possible implementation manner in which the second indication information indicates the offset between the second resource and the first resource, the second indication information is used to indicate the value of the offset between the second resource and the first resource. It can be understood that the value of the offset between the second resource and the first resource in this application may be positive, negative, or zero, which is not limited in this application. Through this embodiment, the offset value can be indicated more accurately, so that physical resources can be more fully utilized.

In an embodiment in which the control information includes the first indication information and the second indication information, optionally, the second indication information is used to indicate multiple second resources, or the number of second resources or the number of repetitions of the second resources is pre-defined. The number of repetitions of the second resource can be understood as the number of the second resource minus one. The multiple second resources in this embodiment may be multiple consecutive second resources in the time domain, or multiple second resources that are not consecutive in the time domain, or multiple consecutive second resources in the frequency domain. The second resource may also be multiple second resources that are not continuous in the frequency domain. Through this implementation manner, the quantity of the second resource can be increased, thereby improving the transmission reliability of the data carried on the second resource.

Through this implementation manner, the number of second resources or the number of repetitions of the second resources can be more accurately indicated, so that the physical resources can be more fully utilized.

Taking the first resource and the second resource illustrated in FIG. 5B or FIG. 5C as an example, the second indication information indicates that the number of the second resource is two, or the second indication information indicates that the number of repetitions of the second resource is one.

In another possible implementation manner in which the second indication information indicates multiple second resources, the second indication information is used to indicate a second index, and the second index corresponds to the number of second resources or the number of repetitions of the second resources . The corresponding relationship between the quantity of the second resource or the number of repetitions of the second resource and the second index may be predefined, or may be configured by the network device (for example, configured by the network device for the second terminal). Through this implementation manner, the quantity of the second resource or the number of repetitions of the second resource can be indicated in a quantified manner, thereby reducing the indication overhead.

Through this implementation manner, suitable resource patterns can be flexibly matched according to different business requirements, so as to meet different business requirements.

Take the first resource and the second resource shown in Figure 5D and Figure 5E as an example, the resource pattern is represented by [M,N] as an example, where M represents the number of resource units in time, and N represents the number of resource units in frequency. . The pattern of the first resource in Fig. 5D and Fig. 5E is [3,3]. The pattern of the second resource in FIG. 5D is [1, 9], and the pattern of the second resource occupies fewer resource units in time, thereby being able to meet the requirements of low-latency services. The pattern of the second resource in FIG. 5E is [9,1], and the pattern of the second resource occupies fewer resource units in frequency, so as to meet the requirements of low-bandwidth or narrow-bandwidth services.

The correspondence between the pattern of the second resource and the third index may be predefined, or configured by the network device (for example, configured by the network device for the second terminal). Through this embodiment, the pattern can be indicated in a quantified manner, thereby reducing the indication overhead.

In another possible implementation manner in which the second indication information indicates the pattern of the second resource, the second indication information is used to indicate the time domain scaling factor and/or the frequency domain scaling factor of the second resource relative to the first resource. The number of resource units included in the first resource and the number of resource units included in the second resource may be the same or different, which is not limited in this application. In the following, for convenience of description, the description is given by taking the same number of resource units included in the first resource as the number of resource units included in the second resource as an example. This implementation manner can be understood as indicating a change of the second resource pattern relative to the first resource pattern, so that more resource patterns can be flexibly indicated with a lower indication overhead.

Taking the first resource and the second resource shown in FIG. 5D as an example, the second indication information may indicate one of the following:

● The time-domain scaling factor of the second resource relative to the first resource is 1/3, which means that the number of resource units of the second resource in time is 1/3 of the number of resource units of the first resource;

● The frequency domain scaling factor of the second resource relative to the first resource is 3, which means that the number of resource units of the second resource in frequency is 3 times the number of resource units of the first resource;

● The time domain scaling factor of the second resource relative to the first resource is 1/3, and the frequency domain scaling factor of the second resource relative to the first resource is 3.

Taking the first resource and the second resource shown in FIG. 5E as an example, the second indication information may indicate one of the following:

●The time-domain scaling factor of the second resource relative to the first resource is 3, which means that the number of resource units of the second resource in time is 3 times the number of resource units of the first resource;

● The frequency domain scaling factor of the second resource relative to the first resource is 1/3, which means that the number of resource units of the second resource in frequency is 1/3 of the number of resource units of the first resource;

● The time domain scaling factor of the second resource relative to the first resource is 3, and the frequency domain scaling factor of the second resource relative to the first resource is 1/3.

In another possible implementation manner in which the second indication information indicates the pattern of the second resource, the second indication information is used to indicate a fourth index, and the fourth index corresponds to the time-domain scaling of the second resource relative to the first resource Coefficient and/or frequency domain scaling factor. The corresponding relationship between the time-domain scaling factor and/or frequency-domain scaling factor of the second resource relative to the first resource and the fourth index may be predefined or configured by the network device (for example, the network device is the second terminal Configuration). Through this embodiment, the time-domain scaling coefficient and/or the frequency-domain scaling coefficient can be indicated in a quantized manner, thereby reducing indication overhead.

Taking the first resource and the second resource illustrated in FIG. 5D and Table 5 as an example, the second indication information may indicate that the fourth index corresponding to the time domain scaling factor of the second resource relative to the first resource is 0.

Taking the first resource and the second resource illustrated in FIG. 5D and Table 6 as an example, the second indication information may indicate that the fourth index corresponding to the frequency domain scaling factor of the second resource relative to the first resource is 1.

Table 6

Fourth index Frequency domain scaling factor 0 1/3 1 3 2 1/2 3 2

Taking the first resource and the second resource illustrated in FIG. 5E and Table 5 as an example, the second indication information may indicate that the fourth index corresponding to the time domain scaling factor of the second resource relative to the first resource is 1.

Taking the first resource and the second resource illustrated in FIG. 5E and Table 6 as an example, the second indication information may indicate that the fourth index corresponding to the frequency domain scaling factor of the second resource relative to the first resource is 0.

In an embodiment in which the control information includes the first indication information and the second indication information, optionally, the second indication information is used to indicate a plurality of second resources, and is used to indicate a pattern of the second resource. Through this implementation manner, the number of second resources can be increased, and appropriate resource patterns can be flexibly matched according to different service requirements, so that the transmission reliability of data carried on the second resources can be improved while meeting different service requirements. For the specific method of indicating multiple second resources and indicating the second resource pattern, reference may be made to the description of the previous implementation manners, and details are not described herein again.

Taking the first resource and the second resource illustrated in FIG. 5F as an example, the second indication information may be used to indicate two second resources, and the pattern used to indicate one second resource is [1, 9].

In a possible implementation in which the pattern of the second resource is predefined, the time domain scaling factor and/or frequency domain scaling factor of the second resource relative to the first resource is predefined. Through this implementation manner, it is not necessary to indicate the time-domain scaling factor and/or the frequency-domain scaling factor, thereby reducing the indication overhead.

In another possible implementation manner of the control information in the method 400, the control information includes first indication information used to indicate the first resource, or the control information includes second indication information used to indicate the second resource, And there is a corresponding relationship between the second resource and the first resource. The corresponding relationship may be predefined or configured by the network device (for example, the network device is configured for the second terminal). When the control information includes the first indication information indicating the first resource, the second terminal can obtain the first resource, and obtain the second resource according to the first resource and the corresponding relationship between the second resource and the first resource. When the control information includes the second indication information indicating the second resource, the second terminal can obtain the second resource, and obtain the first resource according to the second resource and the corresponding relationship between the second resource and the first resource. Through this implementation manner, the indication information in the control information can be reduced, thereby reducing the indication overhead.

In the embodiment in which the second resource and the first resource have a corresponding relationship, optionally, there is a predefined offset between the second resource and the first resource. The offset includes one or more of time domain offset, frequency domain offset, code domain offset, or space domain offset. The size of the first resource may be smaller than or equal to the size of the second resource, for example, the size of the second resource is an integer multiple of the size of the first resource. The size of the first resource may also be greater than the size of the second resource, for example, the size of the first resource is an integer multiple of the size of the second resource. Through this implementation manner, the terminal can quickly obtain the second resource after obtaining the first resource, thereby reducing the processing delay and processing complexity of the terminal.

In the embodiment in which the second resource and the first resource have a corresponding relationship, optionally, the number of second resources or the number of repetitions of the second resource has a corresponding relationship with the size of the first resource. For example, the number of second resources (or the number of repetitions of the second resource) is directly proportional to the size of the first resource, or the number of second resources (or the number of repetitions of the second resource) is inversely proportional to the size of the first resource relationship. The quantity of the second resource (or the number of repetitions of the second resource) and the size of the first resource may also have other relationships (for example, a linear relationship, an exponential relationship, or a logarithmic relationship, etc.), which is not limited in this application. Through this implementation manner, the terminal can quickly obtain the number of second resources or the number of repetitions of the second resource after obtaining the size of the first resource, thereby reducing the processing delay and processing complexity of the terminal.

In the embodiment where the second resource has a corresponding relationship with the first resource, the pattern of the second resource has a corresponding relationship with the pattern of the first resource. For example, the second resource has a predefined time-domain scaling factor and/or frequency-domain scaling factor relative to the first resource. Through this implementation manner, the terminal can quickly obtain the pattern of the second resource after obtaining the pattern of the first resource, thereby reducing the processing delay and processing complexity of the terminal.

In another possible implementation manner of the control information in the method 400, the control information includes third indication information. Before sending the aforementioned data to the network device, the second terminal preprocesses the data according to the third indication information, and the preprocessing includes symbol-level equalization and/or symbol decision. Retransmitting data through symbol-level equalization and/or symbol decision can reduce the influence of channel frequency selectivity on data reception, thereby improving the reliability of data reception.

The method 400 may further include an optional part 440: the first terminal sends a scheduling request to the network device, and the network device receives the scheduling request. The scheduling request is used to request the network device to perform terminal cooperative communication. The network device sends the control information in part 410 to the first terminal and the second terminal according to the scheduling request. Through this implementation method, the joint scheduling of terminal cooperative communication can be initiated based on the request of the terminal, so that scheduling resources can be configured more reasonably and communication performance can be optimized.

In the method 400, optionally, the first terminal and/or the second terminal may determine the role of the control information in part 410 in a variety of ways. By determining the role of the control information, the first terminal and/or the second terminal can learn whether the control information is used for the joint scheduling of the side link and the uplink (that is, for the uplink scheduling and the side link scheduling), or It is used for independent scheduling of the side link and the uplink (that is, used for uplink scheduling or side link scheduling), which can adapt to the coexistence of joint scheduling and non-joint scheduling, and meet backward compatibility.

In a possible implementation manner for determining the role of the control information, the first terminal and/or the second terminal determine that the control information is used for joint scheduling or independent scheduling according to the RNTI. For example, when the first terminal and/or the second terminal successfully descrambling the control information using the first RNTI, it is determined that the control information is used for joint scheduling; when the first terminal and/or the second terminal successfully descrambling using the second RNTI When the control information is used, it is determined that the control information is used for independent scheduling; where the first RNTI and the second RNTI are different RNTIs.

In another possible implementation manner for determining the function of the control information, the first terminal and/or the second terminal determine that the control information is used for joint scheduling or independent scheduling according to a format of the control information. For example, when the format of the control information is the first format, the first terminal and/or the second terminal determine that the control information is used for joint scheduling; when the format of the control information is the second format, the first terminal and/or the second terminal The terminal determines that the control information is used for independent scheduling; where the first format and the second format are different formats. It can be understood that different formats may mean that the control information contains different content, and may also mean that the payload size of the control information is different.

In another possible implementation manner for determining the role of the control information, the first terminal and/or the second terminal determine that the control information is used for joint scheduling or independent scheduling according to the control resource set (CORESET) that carries the control information. Scheduling. For example, when the control information is carried by the first CORESET, the first terminal and/or the second terminal determine that the control information is used for joint scheduling; when the control information is carried by the second CORESET, the first terminal and/or the second terminal determine The control information is used for independent scheduling; wherein, the first CORESET and the second CORESET are different CORESETs. It can be understood that the physical resources contained in different CORESETs can be completely non-overlapping (that is, the physical resources contained in different CORESETs can be completely different), or the physical resources contained in different CORESETs can be partially overlapped (that is, the physical resources contained in different CORESETs can be Parts are the same).

In another possible implementation manner for determining the role of the control information, the first terminal and/or the second terminal determine that the control information is used for joint scheduling or independent scheduling according to the value indicated by the first indication field in the control information. For example, when the first indication field in the control information indicates the first value, the first terminal and/or the second terminal determines that the control information is used for joint scheduling; when the first indication field in the control information indicates the second value, The first terminal and/or the second terminal determine that the control information is used for independent scheduling; where the first value and the second value are different values. Optionally, the first indication field in the above control information may be one or more of the following indication fields: control information format indication field, frequency domain resource allocation domain, time domain resource allocation domain, modulation and coding scheme indication Domain, an indication domain containing the first indication information, an indication domain containing the second indication information, or an indication domain newly introduced in the control information.
