Vehicle to everything (V2X) using New Radio (NR) technology requires the function of discovering resources to implement functions such as unicast and multicast communication establishment. This application uses the existing control channel/data channel (Physical Sidelink Control Channel/Physical Sidelink Shared Channel, PSCCH/PSSCH) physical channel to carry this function. Specifically, PSCCH/PSSCH channel resources at a specific time-frequency position are used to carry discovery information. That is, the transmitting terminal (Tx UE, also referred to as transmitting user equipment) can send discovery information on the PSCCH/PSSCH at a specific time-frequency resource location, and the receiving terminal (Rx UE, also referred to as receiving user equipment) can send discovery information in this Obtain discovery information at a specific time-frequency resource location. Please refer to FIG. 1. FIG. 1 is a schematic diagram of a communication resource configuration solution provided by an embodiment of the present application.

Among them, the filled grids represent resources used to transmit discovery information, and the blank grids represent other data used to transmit. In addition, different from LTE D2D sending synchronization signals in all directions, NR V2X synchronization signals need to consider the directional beam (beam), which introduces multiple synchronization signal blocks (Sidelink SS/PBCH block, S-SSB) to realize the beam Repetition (beam repetition) or beam sweeping (beam sweeping). Correspondingly, discovery resources should also have a certain directionality. Therefore, it is necessary to consider how to associate the directional S-SSB with discovery resources.

In this application, receiving terminal and sending terminal can refer to various forms of user equipment, access terminal, user unit, user station, mobile station, mobile station (Mobile Station, MS), remote station, remote terminal, mobile equipment , User terminal, terminal equipment (terminal equipment), wireless communication equipment, user agent or user device, etc. The terminal device can also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), Handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in 5G networks, or future evolution of the public land mobile network (Public Land Mobile Network, PLMN for short) The terminal equipment in) is not limited in this embodiment of the present application.

Based on the foregoing solution, an embodiment of the present application proposes a communication resource configuration method. Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a communication resource configuration method provided by an embodiment of the present application. The method includes but is not limited to the following steps:

S201: The receiving terminal searches for a discovery resource corresponding to the resource location on the PSCCH/PSSCH physical channel according to the resource location indicated by the discovery resource indication information, where the discovery resource is a resource in the PSCCH/PSSCH resource pool.

Wherein, the resource location indicated by the discovery resource indication information includes the time domain resource location of the discovery resource, and/or the frequency domain resource location of the discovery resource; the time domain resource location is the target time in the control channel/data channel PSCCH/PSSCH resource pool The position of the slot, the frequency domain resource position is the position of the target frequency domain resource in the target time slot, and the granularity indicated by the frequency domain resource position is the same as the granularity of the PSCCH/PSSCH resource pool. The discovery resource indication information may also include the number of repetitions, period, and so on.

Further, in specific implementation, the base station can indicate the discovery resource indication information according to actual application requirements. Among them, the equipment that provides base station functions in 5G NR includes the evolving Node B (gNB); it can also be used in the sending terminal Or, the discovery resource indication information is pre-configured in the receiving terminal. The embodiments of the present application are not limited, and several possible implementation manners are shown below.

In an implementation manner, the base station indicates a group of resource parameters of discovery resources as discovery resource indication information; and/or, a group of resource parameters of discovery resources are pre-configured as discovery resource indication information in the sending terminal or the receiving terminal. Therefore, the sending terminal searches for the discovery resource corresponding to the resource location on the PSCCH/PSSCH physical channel according to the resource location indicated by the discovery resource indication information, so as to send the discovery information on the discovery resource. The receiving terminal searches for the discovery resource corresponding to the resource location on the PSCCH/PSSCH physical channel according to the resource location indicated by the discovery resource indication information. Among them, the resource parameters of the discovery resource include, but are not limited to, time domain resource location, frequency domain resource location, number of repetitions, period, etc. The time domain resource position is the position of at least one target time slot in the PSCCH/PSSCH resource pool selected according to the fixed time domain rule starting from the Kth time slot in each cycle; the frequency domain resource position is from each target time slot The location of the target frequency domain resource selected according to a fixed frequency hopping rule. Specifically, the target time slot position can be determined by the period and time domain offset. For example, in the PSCCH/PSSCH resource pool, starting from the K1 time slot in each cycle, the L1 time slot is selected as the fixed time domain rule. Target time slot. Among them, the fixed time domain law does not impose restrictions, such as selecting a target time slot continuously; or selecting a target time slot every k time slots, and the value of k is a positive integer greater than or equal to 1. Secondly, K1 and L1 are positive integers, and their values can be customized according to requirements. For example, K1 is a positive integer such as 2, 3, and L1 is a positive integer such as 2, 3. Furthermore, the target frequency domain resource is selected from each target time slot according to the fixed frequency hopping rule. If the M1 frequency domain resource is selected as the target frequency domain resource in each target time slot, the fixed frequency hopping rule is determined by the value of M1. Frequency hopping is achieved by selecting the value of M1 according to a fixed rule; for example, the value of M1 is a

positive integer

0, 1, 2, 3, ... that increases in sequence; and the value of M1 is an

even number

0, 2, 4, …; Another example is the value of M1 is an

odd number

1, 3, 5, …, and so on.

For example, see Figure 3. If the period in the PSCCH/PSSCH physical channel is 160ms, K1 is equal to 3, and L1 is equal to 3; then in each period, starting from the third time slot, select 3 consecutive time slots as the target Time slot. If the third time slot is used as the first target time slot, the fourth time slot is used as the second target time slot, and the fifth time slot is used as the third target time slot. Then the frequency domain resource with M1 equal to 0 is selected as the target frequency domain resource from the first target time slot, the frequency domain resource with M1 equal to 1 is selected from the second target time slot as the target frequency domain resource, and the frequency domain resource with M1 equal to 1 is selected from the third target time slot. The frequency domain resource with M1 equal to 2 is selected as the target frequency domain resource.

In an implementation manner, the discovery resource indication information is determined according to the system master information block (Sidelink Master Information Block, SL-MIB) in the synchronization signal block S-SSB, and the resource location of the discovery resource is indicated through the SL-MIB. Specifically, since the available information bits of the SL-MIB are relatively limited, in the 3GPP communication protocol, the resource parameters of the discovery resource are defined in the form of a table, and the table can be stored in the storage device of the receiving terminal or the sending terminal. The sending terminal selects the target entry index in the table according to actual application requirements, and finds the resource parameters of a set of corresponding discovery resources in the table according to the target entry index, as the discovery resource indication information. Then, according to the resource location indicated by the discovery resource indication information, the discovery resource corresponding to the resource location is searched on the PSCCH/PSSCH physical channel to send the discovery information on the discovery resource. In addition, the sending terminal carries the target entry index in the SL-MIB in the S-SSB. Furthermore, after detecting the S-SSB, the receiving terminal finds the resource parameters of the corresponding set of discovery resources in the table through the target entry index in the SL-MIB, as the discovery resource indication information. Then, according to the resource location indicated by the discovery resource indication information, the discovery resource corresponding to the resource location is searched on the PSCCH/PSSCH physical channel. One possible table format is shown below.

Table 1 Resource parameters of discovery resources

表项索引Entry index	时域资源位置Time domain resource location	频域资源位置Frequency domain resource location	周期cycle	重复次数repeat times
0000	To	To	To	To
0101	To	To	To	To
……	To	To	To	To

Among them, each entry index corresponds to a set of resource parameters of discovery resources, and the entry index can be represented by 00, 01, etc. There is no restriction on the way of indicating the position of the time domain resource. For example, it can be indicated by an absolute time offset in each cycle; it can also be indicated by a position offset relative to the S-SSB time. There is no restriction on the way of indicating the location of frequency domain resources. For example, it can be directly indicated by the frequency domain resource number in the PSCCH/PSSCH resource pool. For example, assuming that the channel bandwidth is 10 RBs and the frequency domain granularity unit is 2 RBs, then The frequency domain resources are numbered from 0 to 4, then the values 0 to 4 are the resource numbers; it can also be indicated by the position offset relative to the frequency domain of the S-SSB, please refer to Figure 4, which is an implementation of this application The example provides a schematic diagram of a discovery resource. As shown in the figure, the frequency domain resource position of the discovery resource is upwardly offset by 20 RBs relative to the S-SSB.

Optionally, some resource parameters can be reflected in the table by means of joint indication, such as the time domain resource location and the number of repetitions, and the frequency domain resource and the number of repetitions. For example, taking the time domain resource location and the number of repetitions as an example, please refer to FIG. 5. FIG. 5 is a schematic diagram of a discovery resource provided by an embodiment of the present application. As shown in the figure, two types of joint indication time domain resource locations are shown And the number of repetition implementations, corresponding to the entry index of Table 1, 00 can be used to indicate the first implementation of jointly indicating the location of time domain resources and the number of repetitions, 01 represents the second implementation of jointly indicating time domain resource locations and the number of repetitions the way. The first specific implementation manner for jointly indicating the location of time domain resources and the number of repetitions is to start with the K2 as the first time slot, and select a time slot as the discovery resource every X equals to 1 time slot, and there is a total of L2 in this cycle. Equal to 4 discovery resources, that is, the number of repetitions is 4. The second specific implementation manner for jointly indicating the location of time domain resources and the number of repetitions is to start with the second time slot K2, and select a time slot as the discovery resource every X equals to 3 time slots, and there is a total of L2 in this cycle. Equal to 2 discovery resources, that is, the number of repetitions is 2. For another example, taking frequency domain resources and the number of repetitions, please refer to FIG. 6, which is a schematic diagram of a discovery resource provided by an embodiment of the present application. As shown in the figure, two specific implementation manners for jointly indicating the location of frequency domain resources and the number of repetitions are shown. In both implementation manners, the time domain resource location of the discovery resource is 2 consecutive times starting from the first time slot of K2. The frequency domain resource location of the discovery resource is different. It is obtained by frequency hopping in each time slot according to a fixed rule. For example, if the M2 frequency domain resource is selected as the frequency domain resource in each time slot, you can pass The value of M2 is selected according to a fixed rule to achieve frequency hopping; for example, the value of M2 is a positive integer that increases in sequence; and the value of M2 is a positive integer that decreases in sequence, and so on.

In one implementation, the discovery resource indication information is determined according to the system information block (Sidelink System Information Block, SL-SIB) indicated by the SL-MIB. The SL-MIB indicates the location of the SL-SIB, which is located under the SL-SIB location. The SL-SIB bears discovery resource indication information. The specific implementation manner of the SL-SIB carrying the discovery resource indication information under the SL-SIB location is not limited.

For example, since the amount of information that can be carried by SL-SIB is not limited, the resource parameters of discovery resources can be directly carried in SL-SIB. Specifically, the resource parameter of the discovery resource is pre-configured in the sending terminal or the receiving terminal, and the sending terminal uses the pre-configured resource parameter of the discovery resource as the discovery resource indication information. Then, according to the resource location indicated by the discovery resource indication information, the discovery resource corresponding to the resource location is searched on the PSCCH/PSSCH physical channel to send the discovery information on the discovery resource. In addition, the sending terminal carries the discovery resource indication information in the SL-SIB. After detecting the S-SSB, the receiving terminal decodes the SL-SIB according to the indication of the SL-MIB or according to the fixed resource location to obtain the resource parameter of the discovery resource, and use the resource parameter of the discovery resource as the discovery resource indication information. Then, according to the resource location indicated by the discovery resource indication information, the discovery resource corresponding to the resource location is searched on the PSCCH/PSSCH physical channel. Among them, the specific indication method of the resource parameter can refer to the method described in the above two implementation manners, which will not be repeated here.

In another example, the discovery resource indication information is obtained by looking up a table according to an entry index, the entry index is determined according to the SL-SIB, and the table corresponding to the entry index includes resource parameters. Specifically, in the 3GPP communication protocol, the resource parameters of the discovery resource are defined in the form of a table, and the table can be stored in the storage device of the receiving terminal or the sending terminal. The sending terminal selects the target entry index in the table according to actual application requirements, and finds the resource parameters of a set of corresponding discovery resources in the table according to the target entry index, as the discovery resource indication information. Then, according to the resource location indicated by the discovery resource indication information, the discovery resource corresponding to the resource location is searched on the PSCCH/PSSCH physical channel to send the discovery information on the discovery resource. And the target entry index is carried in the SL-SIB. After detecting the S-SSB, the receiving terminal decodes the SL-SIB according to the instructions of the SL-MIB or according to the fixed resource location, and then finds the resource parameters of the corresponding set of discovery resources in the table according to the table entry index in the SL-SIB , As the indication information of the discovery resource. Then, according to the resource location indicated by the discovery resource indication information, the discovery resource corresponding to the resource location is searched on the PSCCH/PSSCH physical channel. Among them, the specific indication method of the resource parameter can refer to the method described in the above two implementation manners, which will not be repeated here.

It should be noted that the several specific implementations shown in step S201 of the present application can be implemented separately, or can be implemented in combination with any one or more of the several specific implementations described above, and this application is not limited.

S202: The receiving terminal obtains discovery information from the discovered discovery resource.

The sending terminal sends the discovery information on the discovery resource indicated by the discovery resource indication information, and the receiving terminal obtains the discovery information on the discovery resource.

Please refer to FIG. 7. FIG. 7 is a schematic flowchart of a communication resource configuration method provided by an embodiment of the present application. The communication resource configuration method includes but is not limited to the following steps:

S701: The receiving terminal searches for the discovery resource corresponding to the S-SSB according to the association relationship between the synchronization signal block S-SSB and the discovery resource. Then obtain the discovery information on the found discovery resources.

In practical applications, the association relationship between the S-SSB and the discovery resource can be determined by the sending terminal, or it can be agreed upon by the sending terminal and the receiving terminal in the communication protocol. This application is not limited, and several possible association relationships between S-SSB and discovery resources are shown below.

In an implementation manner, each S-SSB is associated with one or a group of discovery resources, where the group of discovery resources includes two or more of the discovery resources. If there are N S-SSBs, then each S-SSB is associated with one or a group of discovery resources, and there are N or N sets of discovery resources, and N is a positive integer greater than or equal to 2. For example, please refer to FIG. 8, which is a schematic diagram of an association relationship provided by an embodiment of the present application. As shown in the figure, S-SSB1, S-SSB2, and S-SSB3 respectively represent different synchronization signal blocks; 1 represents the first group of discovery resources, 2 represents the second group of discovery resources, and 3 represents the third group of discovery resources, where, A group of discovery resources includes two discovery resources. Each S-SSB is associated with a group of discovery resources. For example, S-SSB1 is associated with the first group of discovery resources, S-SSB2 is associated with the second group of discovery resources, and S-SSB3 is associated with the third group of discovery resources. Therefore, the receiving terminal detects the S-SSB1, can find the corresponding first group of discovery resources according to the S-SSB1, and obtain the discovery information from the first group of discovery resources. Similarly, when S-SSB2 and S-SSB3 are detected, they correspond to the second group of discovery resources and the third group of discovery resources, respectively.

In an implementation manner, since multiple S-SSBs may have a quasi co-located (QCL) relationship, the number of S-SSBs is not limited, and this application takes N S-SSBs as an example. Explain that N is a positive integer greater than or equal to 2. If N S-SSBs have a QCL relationship, it is determined that the discovery resources associated with the N S-SSBs also have the same QCL relationship. If it is determined that the discovery resources associated with each of the N S-SSBs also have the same QCL relationship, the discovery information obtained from the discovery resources associated with each of the N S-SSBs is merged. For example, please refer to FIG. 9, which is a schematic diagram of an association relationship provided in an embodiment of the present application. As shown in the figure, S-SSB1, S-SSB2, S-SSB3, and S-SSB4 respectively represent different synchronization signal blocks; 1 represents the first group of discovery resources, 2 represents the second group of discovery resources, and 3 represents the third group of discovery resources Resources, 4 represents the fourth group of discovery resources. Among them, a group of discovery resources includes two discovery resources. If S-SSB1 and S-SSB2 have a QCL relationship, the first group of discovery resources and the second group of discovery resources have the same QCL relationship. Therefore, the sending terminal can flexibly select the resource for sending the discovery information among the first group of discovery resources and the second group of discovery resources according to requirements. The receiving terminal determines that the first set of discovery resources and the second set of discovery resources have the same QCL relationship according to the association relationship between the S-SSB and the discovery resources, and then merges the discovery information obtained from the first set of discovery resources and the second set of discovery resources.

In an implementation manner, since multiple S-SSBs may have a quasi co-located (QCL) relationship, the number of S-SSBs is not limited, and this application takes N S-SSBs as an example. Explain that N is a positive integer greater than or equal to 2. If the N S-SSBs have a QCL relationship, the sending terminal arbitrarily selects one or a group of N or N sets of discovery resources associated with the N S-SSBs, and sends the discovery information as the target discovery resource. Furthermore, the receiving terminal determines the target discovery resource associated with the N S-SSBs, where the target discovery resource is any one or any group of the N or N sets of discovery resources associated with the N S-SSBs. For example, still take the schematic diagram of the association relationship shown in FIG. 9 as an example. If S-SSB1 and S-SSB2 have a QCL relationship, the target discovery resources associated with S-SSB1 and S-SSB2 are not restricted. For example, the first group of discovery resources whose time domain position is closest to S-SSB2 is taken as the target discovery resource. Another example is the second group of discovery resources as the target discovery resources. Taking the first group of discovery resources closest to S-SSB2 in the time domain as the target discovery resource as an example, the sending terminal only sends discovery information on the first group of discovery resources, and the receiving terminal detects S-SSB1 or S-SSB2 At that time, only the first group of discovery resources are used to obtain discovery information. According to the QCL relationship of the S-SSB, the discovery resources used to carry discovery information are reduced, which can make better use of channel resources and improve channel resource utilization.

In an implementation manner, since multiple S-SSBs may have a quasi co-located (QCL) relationship, the number of S-SSBs is not limited, and this application takes N S-SSBs as an example. Explain that N is a positive integer greater than or equal to 2. If N/M groups of S-SSBs are included in N S-SSBs, and the S-SSBs included in each group of S-SSBs have a QCL relationship, and the QCL relationship is fixed, then each group of S-SSBs Corresponding to one or a group of discovery resources, M is the number of repetitions. Specifically, if the QCL relationship of the S-SSB is fixed, the number of repetitions is 2; the number of S-SSBs is a maximum of 4, in fact, the number of S-SSBs with different QCL relationships is 4/2 = 2. Then only 2 groups will be configured when configuring discovery resources. For example, still take the schematic diagram of the association relationship shown in FIG. 9 as an example. If S-SSB1 and S-SSB2 have the same QCL, and S-SSB3 and S-SSB4 have the same QCL, then S-SSB1 and S-SSB2 can be called a set of S-SSB, S-SSB3 and S-SSB4 Called a set of S-SSB. When configuring the discovery resource, the sending terminal can associate one or a group of discovery resources corresponding to each group of S-SSBs for configuration. For example, S-SSB1 and S-SSB2 are associated with the first group of resources, and S-SSB3 and S-SSB4 are associated with the third group of resources. The number of discovery resources can be reduced, which is conducive to the receiving terminal to obtain discovery information. Therefore, when the receiving terminal detects S-SSB1 or S-SSB2, it finds the corresponding first group of discovery resources and obtains the discovery information from the first group of discovery resources; when the receiving terminal detects S-SSB3 or S-SSB4 , Find the corresponding third group of discovery resources, and obtain the discovery information from the third group of discovery resources.

It can be seen from this that, by associating the synchronization signal block S-SSB with the discovery resource in the embodiment of the present application, it is possible to find and monitor the corresponding discovery resource after the S-SSB is detected, thereby reducing communication resource consumption.
