Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The embodiment of the present application provides a device group management method, which is applicable to various wireless communication systems capable of data or signaling transmission through a side link. For example: global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (general packet radio service, GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), general mobile communication system (Universal mobile telecommunication system, UMTS), worldwide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) system or new radio (NR), etc. In particular, this device group management method is particularly suitable for vehicle-to-vehicle (V2V) wireless communication systems in NR scenarios.

The first terminal device or the second terminal device involved in the embodiments of the present application may be user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, Terminals, wireless communication equipment, user agents, or user devices can also be cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital processing ( personal digital assistant, PDA), handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, in-vehicle devices, roadside units, wearable devices, terminal devices in 5G networks, or future evolution of public land The terminal devices in the mobile communication network (public land mobile network, PLMN), etc., are not limited in the embodiment of the present application. To facilitate understanding, in the embodiments of the present application, the first terminal device or the second terminal device will be collectively described.

Please refer to FIG. 1, which is a schematic structural diagram of a communication system provided by an embodiment of the present application. It can be seen from FIG. 1 that the communication system mainly includes a first terminal device and a second terminal device. Here, a side link is established between the first terminal device and the second terminal device, and the two can transmit data or signaling through the side link. In practical applications, the first terminal device or the above-mentioned second terminal device can realize the functions of joining, leaving, and sharing information or data with the member devices of the device group under the scheduling of the network device (such as the base station, etc.) . However, when the first terminal device or the second terminal device is in an area without network coverage, the first terminal device or the second terminal device cannot continue to implement the aforementioned functions because it cannot be connected to the network device.

Therefore, the main technical problem solved by the embodiments of the present application is: how to complete the grouping of terminal devices and the management of the device group without the assistance of network devices, so as to solve the problem that terminal devices cannot be grouped and managed in scenarios without network coverage. Problems to improve the applicability and practicality of the equipment group management method.

Please refer to FIG. 2, which is a schematic flowchart of a method for managing a device group according to an embodiment of the present application. This device group management method is suitable for the communication system shown in FIG. 1. As can be seen from Figure 2, the method may include the following steps:

S200: The first terminal device sends the first information to the second terminal device.

In some feasible implementations, the first terminal device may send the first information to the second terminal device through a certain side link between it and the second terminal device (the first side link is used in the following to replace the description) . The first information includes at least the device identities of all members in the device group where the first terminal device is located (for ease of understanding and distinction, the first device group will be substituted for the description below). It should be noted here that the first terminal device can be regarded as the leader of the first device group, and it can complete the management of the first device group through information interaction with each member of the first device group. The above-mentioned second terminal device is not a member of the first device group at the current moment.

In specific implementation, when detecting that the preset sending period is reached, the first terminal device may first determine the first information. For example, the first terminal device may use the first information sent to the second terminal device when the last sending period arrives as the first information to be sent this time. For another example, the first terminal device can also detect all the members (here assumed to be N1 members) included in the first device group at the current moment, obtain the device identification of each member of the N1 members, and use these N1 devices The identifier generates the above-mentioned first information. Here, N1 is a positive integer greater than or equal to 1 and less than or equal to N0. N0 is the preset upper limit of the number of members of the first device group, and N0 is a positive integer greater than or equal to 1. It should also be noted here that the device identification of a certain member may be the physical identification of the member, or may be the location of the time-frequency resource reserved by the first terminal device for the member, and this application does not make specific restrictions. After the first terminal device determines the first information, it can use the physical sidelink control channel (PSCCH) and the physical sidelink broadcast channel (PSBCH) on the first sidelink. ) Or a channel such as a physical sidelink shared channel (PSSCH) to send the first information to the second terminal device. Optionally, the first terminal device may send the foregoing first information to the second terminal device in the form of broadcast, multicast, or unicast.

Please refer to FIG. 3 together below. FIG. 3 is a schematic diagram of some possible information formats provided by an embodiment of the present application. As shown in Figure 3, the embodiment of the present application provides four information formats, including format 1, format 2, format 3, and format. The specific content contained in the information in different formats is different. To put it another way, it is for the recipient of the information. After it has determined which format the received information belongs to, it can determine which fields are included in the received information. What information the field contains to determine whether and how to interpret the information it receives.

In an optional implementation, the first terminal device may generate the foregoing first information according to Format 1. In other words, the above-mentioned first information may include a content indication identifier (corresponding to the F field in format 1), a format identifier (corresponding to the type field in format 1), a device quantity parameter (corresponding to the length field in format 1), and N1 device IDs (corresponding to the device ID 1, device ID 2, device ID 3, etc. in format 1) and other content. Here, the foregoing content indication identifier is specifically used to indicate whether the first information is empty. For example, suppose the above content indication identifier is a bit, and when the value of the bit is 1, it may indicate that the first information is not empty. When the value of this bit is 0, it may indicate that the above-mentioned first information is empty. The above-mentioned format indication identifier is the first identifier state, and is used to indicate that the format of the first information is format 1. It should be noted that the embodiments of this application provide 4 formats, therefore, the above-mentioned format indicator can have at least four different identification states, including the first identification state described above and the second identification state that will be mentioned later. , The third identification status and the fourth identification status, in this way, the above four formats can be correspondingly indicated through the four different states of the format indicator identification. Here, the format identification of the first identification state is used to correspond to the indication format 1, the format identification of the second identification state is used to correspond to the indication format 2, the format identification of the third identification state is used to correspond to the indication format 3, and the format of the fourth identification state The identifier is used to correspond to the instruction format 4. Here, different identification states may specifically be embodied as different values of the format identification. The aforementioned device quantity parameter indicates the current number of members included in the first device group, and also indicates the number of device identifiers included in the first information. Using the preset format to send the first information can enable the receiver of the first information to correctly parse the first information according to the format, which can reduce the receiver’s parsing operations on invalid first information, and ensure the first information. 1. The accuracy and reliability of the transmission of information.

In yet another optional implementation, the first terminal device may also generate the foregoing first information according to Format 3. That is to say, the above first information not only includes the content indication identifier (corresponding to the F field in format 3), format identifier (corresponding to the type field in format 3), and the first device quantity parameter (corresponding to the length1 field in format 3) , It may also include the second device quantity parameter (such as the length2 field in format 3), the device identifiers of the N3 members that need to perform resource reconfiguration, and the resource reconfiguration parameters corresponding to each member (such as the device identifier 1 in format 3). And the resource reconfiguration parameter 1) corresponding to the device identifier 1. Here, N3 is a positive integer greater than or equal to 1 and less than or equal to N1. The foregoing resource reconfiguration parameters may include transmission power configuration parameters, the maximum number of hops for multi-hop transmission, time-frequency resource parameters, etc., which are not specifically limited in this application. The aforementioned second device quantity parameter indicates the number of members that need to perform resource reconfiguration (ie, N3). The first terminal device sends the first information generated in format 3 by broadcast or multicast. On the one hand, the members of the first device group can implement resource reconfiguration based on the first information, and on the other hand, it can also make non- A terminal device (such as a second device) that is a member of the first device group can determine whether to request to join the first device group based on the first information. One type of information implements two functions at the same time, avoiding the increase in the complexity of the information format caused by using different information to implement different functions, and simplifies the device group management method.

It should be added that before the first device group is established, the first terminal device may first determine whether there are one or more device groups in its surroundings. For example, the first terminal device may try to search for and receive information in the same format as the above-mentioned first information. If the first terminal device receives one or more pieces of information in the same format as the above-mentioned first information, it can be determined that there are group leaders of one or more device groups in its surroundings. Then, the first terminal device may send information to the leader of one or more device groups to request to join the one or more device groups. If the group leader of the one or more device groups refuses to join the first terminal device, the first terminal device may establish a first device group by itself. Or, if the first terminal device determines that there is no group leader of any device group in its surroundings, it can also establish a first device group by itself. It can be understood that after establishing the first device group, the first terminal device can send information in the same format as the first information to its surrounding terminal devices, so that the surrounding terminal devices can initiate requests to it. Join this newly created first device group.

S210: If the second terminal device determines that it will request to join the first device group where the first terminal device is located, generate second information.

In some feasible implementation manners, after receiving the first information, the second terminal device may generate second information if it is determined according to the first information that it wants to request to join the first device group. Here, the foregoing second information may include the device identifiers of N2 members among the foregoing N1 members. The signal quality measurement result between each of the N2 members and the second terminal device is less than the preset first threshold. Here, N2 is a positive integer greater than or equal to 1 and less than or equal to N1.

In specific implementation, after receiving the above-mentioned first information, the second terminal device may first measure the signal quality between the first terminal device and the second terminal device to obtain the signal quality measurement result (for the convenience of distinction, the following will be The first signal quality measurement result replaces the description). Optionally, the foregoing first signal quality measurement result may specifically be reference signal received power (RSRP) or reference signal received quality (RSRQ) between the first terminal device and the second terminal device. ) And other parameters, this application does not make specific restrictions. After detecting the first signal quality measurement result, the second terminal device may determine whether the first signal quality measurement result is equal to or greater than the preset fourth threshold. If the second terminal device determines that the first signal quality measurement result is equal to or greater than the fourth threshold, it is determined that it can request to join the aforementioned first device group. If the second terminal device determines that the first signal quality measurement result is less than the fourth threshold, it may determine that it does not request to join the first device group.

It should be added that after the second terminal device receives the same type of information as the first information sent by the group leader of multiple device groups including the first device group, the second terminal device can detect this information separately. The channel quality between each of the multiple team leaders and the second terminal device is used to obtain multiple channel quality measurement results. Then, the second terminal device may select one or more channel quality measurement results greater than the fourth threshold from the multiple channel quality measurement results, and randomly select a channel quality measurement result from the one or more channel quality measurement results As a result, the device group corresponding to the randomly selected channel quality measurement result is determined as the device group that it wants to join. Alternatively, the second terminal device may also select a channel quality measurement result with the largest value from one or more channel quality measurement results, and determine the device group corresponding to the channel quality measurement result with the largest value as the device group it wants to join. For example, suppose that the second terminal device receives the leader of the first device group (that is, the above-mentioned first terminal device), the leader of the third device group (assuming the third terminal device), and the leader of the fourth device group (here (Assumed to be the fourth terminal device) after the first, eighth, and ninth information sent by the second terminal device, the second terminal device can separately communicate with the above-mentioned first terminal device, third terminal device, and fourth terminal device. The quality is measured to obtain the first channel quality measurement result, the second channel quality measurement result, and the third channel quality measurement result. Then, assuming that the second terminal device determines that the first channel quality measurement result, the second channel quality measurement result, and the third channel quality measurement result are all greater than the foregoing fourth threshold, it can randomly select the first channel quality measurement result, the second channel quality measurement result, and the second channel quality measurement result. A first channel quality measurement result is selected from the channel quality measurement result and the third channel quality measurement result. Assuming that the first channel quality measurement result is randomly selected, the second terminal device can determine that it can request to join the aforementioned first device group. Alternatively, the second terminal device may also select the largest value among the above-mentioned first channel quality measurement result, second channel quality measurement result, and third channel quality measurement result. Assuming that the value of the second channel quality measurement result is the largest here, the second terminal device determines that it can request to join the third device group.

After the second terminal device determines that it wants to request to join the first device group, it may first parse the first information to determine that the first device group includes N1 members based on the N1 device identifiers included in the first information. In the scenario where the type of the first information is format 1, after receiving the first information, the second terminal device may first extract the content indicator included in the first information, and determine the content indicator according to the content indicator. Whether the first message is empty. If the first terminal device determines that the first information is not empty according to the content indication identifier, it continues to extract the format identifier included in the first information, and then determines the format of the first information according to the identifier status of the format identifier. When the second terminal device determines that the format of the first information is format 1, it can be determined that the first information is mainly used by the first terminal device to broadcast to its surrounding terminal devices (including members or non-members of the first device group) Or multicast all members of the current first device group, that is, the first information includes the member identifiers of all members in the first device group. Then, the second terminal device can extract the device quantity parameter (ie, N1) contained in the first information, and extract N1 device identifiers from the N1 fields after the length field. In the scenario where the type of the first information is format 3, the second terminal device's parsing process for the first information is the same as the above-mentioned parsing process, and the second terminal device only needs to obtain the N1 devices included in the first information The identification can stop the analysis of the first information.

After obtaining the above N1 device identifiers, the second terminal device can respectively detect the channel quality between each of the N1 members corresponding to the above N1 device identifiers and the second terminal device to obtain N1 channel quality measurement results . Thereafter, the second terminal device may determine N2 channel quality measurement results from the above N1 channel quality measurement results according to the preset first threshold. Here, the N2 channel quality measurement results are all less than the foregoing first threshold. In other words, the channel quality between the N2 members corresponding to the N2 channel quality measurement results and the second terminal device is poor.
