Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In SL communication, a resource allocation manner of cooperation between terminals is considered to reduce transmission collision problems caused by hidden nodes, half duplex restrictions, and the like in a resource allocation mode selected by the terminals autonomously. At present, the sending of the cooperation information between the terminals can be triggered by the cooperation request information or event triggering, wherein the cooperation request information triggers to send the cooperation request information to another terminal which needs to request cooperation for one terminal, and after receiving the request information, the other terminal sends the cooperation information to one terminal; and after the event triggering is carried out, after the transmission collision problem caused by hidden nodes, half-duplex limitation and the like is detected for one terminal, the cooperative information is actively sent to other terminals so as to avoid the problem. The collaboration request information may include a use resource of the collaboration terminal for sending collaboration information, and information such as priority and delay requirements of data transmission and collaboration information type of the terminal for requesting collaboration information, which is used for the collaboration terminal to send collaboration information. The cooperative information may include resource location information that the cooperative terminal suggests to request the cooperative terminal to select or a transmission collision indication detected by the cooperative terminal.
In SL communication, determining the resources used by the cooperative terminals to transmit the cooperative information may include the following ways: (1) resources indicated in the cooperation request information, (2) resources autonomously selected by the cooperative terminal through interception, (3) resources requested by the cooperative terminal to the base station for transmitting the cooperation information, (4) resources bound to a terminal ID or a subchannel ID or the like are configured at a higher layer, that is, the cooperative terminal can transmit the cooperation information through the resources bound to the terminal ID or the subchannel ID or the like, similarly to the PSFCH channel in the existing NR system.
Wherein the mode (1) can be used only for resource determination for transmitting the cooperation information based on the cooperation request information. If the mode (3) is adopted, the transmission of the cooperative information has higher time delay, and the cooperative terminal is required to support the connection communication with the base station. Mode (4) requires dividing dedicated resources for transmission of the cooperative information, and may consider transmission of the cooperative information for which the data amount is relatively small, such as whether or not a potential transmission collision indication occurs. The cooperative terminal can directly select resources to transmit the cooperative information in the resource pool in the resource allocation mode selected by the current terminal, and compared with the mode (3), the mode (2) has lower time delay and can transmit the cooperative information with larger data quantity to transmit. At present, the problem of transmission priority and transmission configuration parameters of the cooperative information needs to be further determined no matter which cooperative information is transmitted.
In the non-cooperative mode, the side link information sent by the legacy terminal is mainly triggered and sent by the higher layer service, and the priority of the terminal physical layer channel PSSCH (Physical sidelink share channel, physical side link shared channel)/PSCCH (Physical sidelink control channel ) is mainly determined according to the priority corresponding to the higher layer service logic channel. The existing PSFCH priorities bound with the PSSCH traffic channels and the terminal ID are determined according to the corresponding PSSCH traffic channels.
However, when the cooperative terminal transmits the cooperative information, there is a case that no higher-layer service logic channel triggers transmission, and the priority rule of the cooperative terminal needs to be redetermined to further determine the transmission configuration parameters of the information and process channel transmission collision between SL and UL and between SL and SL. And if the PSFCH channel is used to transmit the cooperative information, it is also necessary to re-determine whether the priority of the cooperative PSFCH is the same as the priority of the corresponding PSSCH traffic channel where transmission collision may occur.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
Fig. 1 (a) is a flowchart of an embodiment of the method of the present application, fig. 1 (b) is a schematic diagram of a default priority determination rule of an embodiment of the method of the present application, fig. 1 (c) is a schematic diagram of another default priority determination rule of an embodiment of the method of the present application, and fig. 1 (d) is a schematic diagram of a transmission configuration parameter determination of an embodiment of the method of the present application.
The application provides a configuration method for transmitting cooperative information between side link terminals, which comprises the following steps 101-102:
and 101, cooperative information, which is used for assisting the terminal to perform resource selection or resource reselection in the side link communication, and has transmission priority.
In step 101, the first terminal determines a transmission priority of the cooperation information.
After the first terminal receives the collaboration request information sent by the other terminals, or after the first terminal detects an event (such as detecting that the other terminals meet transmission collision due to hidden nodes or half-duplex limitation, and the like, and meet the condition of periodically sending the collaboration information), the first terminal sends one piece of collaboration information to assist the other terminals in resource selection or resource reselection, so as to avoid the problems of transmission collision and the like caused by hidden nodes or half-duplex limitation, and the like.
The network may configure a variety of collaboration information, and different collaboration information may contain different content or be transmitted using different channels.
For example, the network configures at least three kinds of collaboration information to be the first collaboration information, the second collaboration information, and the third collaboration information, respectively. The first collaboration information may include at least one information of a source terminal ID of the collaboration information, a destination terminal ID of the collaboration information, a time-frequency resource that the first terminal suggests to use, aging of the collaboration information, a purpose of use of the collaboration information (e.g., avoiding half duplex or hidden node problems), and the like. The second cooperative information may include at least one information of a source terminal ID of the cooperative information, a destination terminal ID of the cooperative information, a time-frequency resource that the first terminal does not suggest to use, aging of the cooperative information, a purpose of use of the cooperative information (e.g., avoiding a half duplex or hidden node problem), and the like. The third collaboration information may include at least one of a potential transmission collision indication, a potential transmission collision resource location indication, and the like. Wherein the first cooperation information and the second cooperation information can be indicated by PSCCH/PSSCH; the third cooperation information may be indicated using a channel similar to the PSFCH. It should be noted that the PSCCH/PSSCH and PSFCH used for the cooperative information transmission herein may be different from those of the existing system, the content and format of the transmission corresponding to the PSCCH/PSSCH and PSFCH, and the determination method of the usage resource. The first, second, and third collaboration information may be classified as different types of collaboration information, or two of them may be classified as the same type of collaboration information. For example, the first collaboration information and the second collaboration information may be classified into the same type of collaboration information, and the first collaboration information and the third collaboration information may be different types of collaboration information.
In step 101, the method for determining the transmission priority of the collaboration information by the first terminal includes at least one of the following modes one to four:
and in the first mode, the transmission priority of the cooperative information is configured through network protocol signaling.
The network may configure the transmission priority of the collaboration information through protocol signaling. Further alternatively, the network may configure multiple transmission priorities to correspond to different levels or types of collaborative information delivery requirements. The method for configuring the transmission priority of the cooperative information through the network protocol signaling comprises at least one of the following steps:
the transmission priority is configured independently for different types of collaboration information. For example, the transmission priority is independently configured for the first collaboration information, the second collaboration information and the third collaboration information.
And independently configuring transmission priority for the periodically transmitted collaboration information. For example, when the first terminal has multiple configuration periodic collaboration information to send, each configuration periodic collaboration information may correspond to a transmission priority.
The transmission priority is configured independently for different events triggering the transmission of the collaboration information. For example, transmission priorities based on an HARQ (Hybrid Automatic Repeat Request ) ACK/NACK measurement trigger, based on a transmission resource collision measurement trigger are different. Further, different thresholds for event-related measurements triggering the transmission of collaboration information may be configured with different priorities. For example, the overlapping rate of two transmission resources of a transmission collision occurring due to half duplex limitation or hidden node problem is measured, and the priority of corresponding cooperative information is different at different overlapping rates.
In step 101, when the transmission priority of the collaboration information is configured through network protocol signaling, a default priority determination rule is allowed to be configured.
The method for configuring default priority determining rules comprises at least one of the following rules one to five:
fig. 1 (B) provides a schematic view of a usage scenario of rule one and rule two, as shown in fig. 1 (B), a first terminal sends cooperation information to a terminal C to solve the hidden node problem, the first terminal detects resource positions reserved by information sent by a terminal a and a terminal B to the first terminal, and the corresponding transmission priorities are respectively transmission priority 1 and transmission priority 2.
The terminals in the resources reserved by the terminals herein include the first terminal and other terminals than the first terminal. Alternatively, the resources already reserved by the terminal may include resources scheduled to be reserved in the first terminal resource selection procedure. Alternatively, the resources already reserved by the terminal may further include reserved resources indicated in the collaboration information received by the first terminal.
And setting the transmission priority of the first rule and the cooperation information as the highest priority among the corresponding transmission priorities on the reserved resources detected by the first terminal.
In rule one, the transmission priority of the collaboration information corresponds to the highest priority between transmission priority 1 and transmission priority 2.
And setting the transmission priority of the second rule and the cooperation information as the lowest priority among the transmission priorities corresponding to the reserved resources detected by the first terminal.
In rule two, the transmission priority of the collaboration information corresponds to the lowest priority between transmission priority 1 and transmission priority 2.
Fig. 1 (c) provides a schematic view of a usage scenario of rules three to five, as shown in fig. 1 (c), a first terminal detects that a resource reserved by a terminal D for sending information to the first terminal collides with a resource reserved by a terminal E, and needs to send cooperation information to the terminal D or the terminal E to indicate resource reselection, and the transmission priorities corresponding to the resource reserved by the terminal D for sending information to the first terminal and the resource reserved by the terminal E are respectively a transmission priority 3 and a transmission priority 4.
And setting the transmission priority of the collaboration information as the highest priority among the corresponding transmission priorities on the detected resources which are potentially subject to transmission collision.
In rule three, the transmission priority of the collaboration information corresponds to the highest priority between transmission priority 3 and transmission priority 4.
And setting the transmission priority of the collaboration information as the lowest priority among the corresponding transmission priorities on the detected resources which are potentially subject to transmission collision.
In rule four, the transmission priority of the cooperative information corresponds to the lowest priority between transmission priority 3 and transmission priority 4.
And fifthly, setting the transmission priority of the collaboration information as the priority of the resource corresponding to the collaboration information destination terminal in the detected resources which are potentially subject to transmission collision.
In the fifth rule, the terminal D is used as a terminal for destination of the cooperative information, and the transmission priority of the cooperative information sent by the first terminal to the terminal D corresponds to the transmission priority of the corresponding resource of the terminal D in the transmission collision resource, that is, the transmission priority 3.
It should be further noted that, the method for configuring the default priority determining rule may be an extension of the above rule, for example, the transmission priority of the collaboration information is set to be an average priority among the transmission priorities corresponding to the reserved resources detected by the first terminal, and a randomly selected priority among the transmission priorities corresponding to the reserved resources detected by the first terminal. For example, the transmission priority of the cooperative information is set to be an average priority among the transmission priorities corresponding to the resources potentially subject to the transmission collision detected by the first terminal, and a randomly selected priority among the transmission priorities corresponding to the resources potentially subject to the transmission collision detected by the first terminal.
Further alternatively, different types of collaboration information may employ different default transmission priority determination rule methods as described above. For example, the first collaboration information/the second collaboration information adopts the rule one or the rule two; the third cooperation information adopts the rule III, the rule IV or the rule five.
And secondly, indicating the transmission priority of the collaboration information through the collaboration request information.
The collaboration request information, namely, the request information sent by other terminals to the first terminal, triggers the first terminal to send collaboration information to the first terminal for resource selection or resource reselection.
When the transmission priority of the cooperation information is indicated by the cooperation request information, the transmission priority of the cooperation information is implicitly or explicitly indicated by the cooperation request information:
for example, the implicit indication method may be that the implicit indication method carries a priority corresponding to the sending data of the collaboration request terminal in the collaboration request information, where the priority is the priority of the collaboration information.
For example, the collaboration request information explicitly indicates a collaboration information priority. Alternatively, the priorities of the different types of collaboration information may be explicitly indicated.
And in the third mode, the first terminal determines the transmission priority of the cooperative information in the device implementation.
And fourthly, obtaining the transmission priority of the cooperative information from the obtained transmission priority according to a preset criterion.
The method for obtaining the transmission priority of the cooperative information according to the preset criterion from the obtained transmission priority comprises at least one of the following cases one to three:
and in the first case, the acquired transmission priority and the finally determined transmission priority have a corresponding relation, and the transmission priority of the cooperative information is obtained according to the corresponding relation.
The network configures the first terminal to select one of the first mode, the second mode and the third mode to determine the transmission priority of the cooperative information. For example, when the network configures the transmission priority of the cooperative information in a manner, the manner one is selected. For another example, when the network configures a transmission priority of the cooperative information in the second mode, the second mode is selected. For another example, if neither of the first and second networks is configured, then the third mode is selected.
And in the second case, selecting the highest or lowest priority from the acquired transmission priorities as the transmission priority of the cooperation information.
The first terminal can combine in a mode one to determine the transmission priority of the cooperative information. For example, when the network configures the priority of the cooperative information in the first and second modes, the network configuration or the first terminal decides to select the highest or lowest priority among the transmission priorities of the cooperative information determined in the first and second modes as the priority of the cooperative information.
And thirdly, selecting the highest priority from the acquired transmission priority of the cooperative information and the transmission priority of other information transmitted simultaneously with the cooperative information as the transmission priority of the cooperative information.
In the third case, if the cooperative information and other information of the first terminal are transmitted on one channel, the channel transmission priority is the highest priority among the transmission priority of the cooperative information and the transmission priority of the other information transmitted simultaneously with the cooperative information. For example, the first terminal sends service information and collaboration information to one terminal at the same time, and collaboration information is transmitted in MACCE (Media access controlControlElement, media access control unit) on a PSSCH corresponding to the service information, and then the priority corresponding to the PSSCH is the highest priority among the transmission priorities of the service information and collaboration information.
It should be further noted that, under different usage scenarios, different manners may be used for determining the priority of the same type of collaboration information, or different implementation schemes under the same manner described above, for example, when the terminal that receives the first collaboration information only suggests that resources are used for resource selection based on the first collaboration information, the priority of the first collaboration information may be determined by the second manner; when the terminal receiving the first cooperation information is used for resource selection based on the first cooperation information and the channel state intercepted by the terminal, the priority of the first cooperation information can be determined in a mode one.
In step 101, the manner in which the first terminal obtains the network protocol signaling may be that the base station end sends, other terminals send, the device obtains according to the manner in which the protocol is written, or the manner in which the above several manners are determined jointly. The protocol signaling may be higher layer RRC signaling, physical layer signaling.
Step 102, sending configuration parameters of the collaboration information correspond to transmission priorities of the collaboration information.
In step 102, the first terminal determines a transmission configuration parameter of the cooperative information, where the transmission configuration parameter includes at least one of a transmission MCS (Modulation and Coding Scheme ) of the cooperative information, a number of transmission subchannels, a maximum transmission power, and a maximum retransmission number of the cooperative information.
In step 102, the method for determining the transmission configuration parameter of the collaboration information by the first terminal includes at least one of the following modes one to three:
in the first mode, the transmission configuration parameters of the collaboration information are configured through network protocol signaling.
The network may independently configure the transmit configuration parameters for different priorities of different types of collaboration information. The network configured cooperative information sending parameter comprises at least one of the sending MCS of the cooperative information, the number of transmission sub-channels, the maximum sending power, the maximum retransmission times of the cooperative information and the like.
Further alternatively, the network independently configures the transmission configuration parameters for different priority ranges of different types of collaboration information. I.e. the same priority range of the same type of collaboration information corresponds to the same transmission configuration parameters. For example, assuming that the transmission priority 1 and the transmission priority 2 of the first cooperative information belong to the same priority range, the first cooperative information of the transmission priority 1 and the first cooperative information of the transmission priority 2 correspond to the same transmission configuration parameter.
It should be further noted that, the network may configure the same type of collaboration information under different priorities to correspond to the same transmission configuration parameters.
And determining the sending configuration parameters of the cooperative information based on a congestion control method.
The method may be used in a scenario where the first terminal uses resources selected autonomously based on interception for transmitting the cooperation information.
Fig. 1 (d) is a schematic diagram of determining a transmission configuration parameter based on a congestion control method of a conventional system, where the congestion control method is used to determine a transmission configuration parameter of a traffic channel PSSCH. The main congestion control method is that a plurality of transmission priorities, CBR (channel busy rate ) grades and PSSCH sending parameter configuration mapping relations are configured at a high layer, different transmission priorities are configured corresponding to different CBR grades, and each mapping relation comprises a transmission priority threshold (sl-priorityThreshold), a default PSSCH sending parameter configuration indication (sl-DefaultTxConfigIndex), a CBR grade configuration index (sl-CBR-ConfigIndex), a CBR grade index and a PSSCH sending parameter configuration index map (sl-Tx-ConfigIndexList).
The first terminal determines a corresponding mapping relation between the CBR grade and PSSCH transmission parameter configuration according to the PSSCH transmission priority, determines a CBR grade index in CBR grade configuration in the mapping relation according to measurement CBR, further determines a final PSSCH transmission parameter configuration index according to mapping between the CBR grade index and the PSSCH transmission parameter configuration index, and acquires PSSCH transmission parameter configuration according to the PSSCH transmission parameter configuration information based on the CBR. And if the terminal does not conduct CBR measurement, determining PSSCH transmission parameter configuration indexes according to default PSSCH transmission parameter configuration instructions.
And thirdly, indicating the sending configuration parameters of the collaboration information through the collaboration request information.
In the third aspect, the cooperative request information explicitly indicates a transmission configuration parameter of the cooperative information, where the transmission configuration parameter includes at least one information of a transmission MCS of the cooperative information, the number of transmission subchannels, a maximum transmission power, a maximum retransmission number of the cooperative information, and the like.
In step 102, optionally, if the method for determining the transmission configuration parameters of the collaboration information includes at least two of the first to third modes, each transmission configuration parameter of the collaboration information is determined jointly according to the existing determination method.
That is, the transmission configuration parameters of the cooperative information are determined by the combination of the first mode and the third mode, for example, the lowest value of the first mode to the third mode is selected by the MCS, the lowest value of the first mode to the third mode is selected by the maximum retransmission number selection method, the lowest value of the first mode to the third mode is selected by the maximum transmission power selection method, and the lowest value of the first mode to the third mode is selected by the subchannel number selection method.
In step 102, the manner in which the first terminal obtains the network protocol signaling may be that the base station end sends, other terminals send, the device obtains according to the manner in which the protocol is written, or the manner in which the above several manners are determined jointly. The protocol signaling may be higher layer RRC signaling, physical layer signaling.
The invention provides a method for configuring transmission of cooperative information among SL terminals, which is a method for determining priority of SL physical layer information, is applied to side link communication and is used for assisting the terminals to process the problem of transmission collision among different channels.
Fig. 2 is a flowchart of an embodiment of a method of the present application for a network device.
The method according to any one of the embodiments of the first aspect of the present application, for a network device, includes the following steps 201 to 202:
step 201, a first signaling for indicating transmission priority of the collaboration information is sent.
