Alternatively, the network device may also individually send the group RNTI and the identifier of the terminal device in the terminal device group to each terminal device in the terminal device group.

The manner in which the network device performs resource scheduling based on the grouping of the terminal device will be described in detail below.

Referring to FIG. 2 , an embodiment of the present application provides a resource determination method, which can be applied to the foregoing communication system. The method includes the following steps.

S201: The network device sends resource configuration information to a plurality of terminal devices included in a terminal device group, where the resource configuration information is used to indicate a first transmission resource. Exemplarily, FIG. 2 illustrates a network device and a terminal device group, and the terminal device group includes three terminal devices, namely UE1, UE2 and UE3.

The first transmission resource includes a first uplink resource, and the first uplink resource refers to a transmission resource that can be used by at least one terminal device in the terminal device group to send uplink data. Considering that there are multiple resource scheduling methods for the transmission resources used by the network device to send uplink data to the terminal device, such as dynamic scheduling (dynamic grant, DG) and semi-static scheduling (configured grant, CG), under different scheduling methods, the network device indicates The first transmission resources are different. The network device may determine different resource configuration information for different resource scheduling methods.

For example, when the network device adopts a dynamic scheduling method, that is, resource scheduling needs to be performed before each data transmission, the first transmission resource indicated by the network device to the terminal device group may include the time domain resources and/or frequency resources scheduled this time. Domain resources, the network device sends resource configuration information to multiple terminal devices in the terminal device group, where the resource configuration information includes indication information for indicating the time domain resources and/or frequency domain resources scheduled this time.

For another example, when the network device adopts a semi-persistent scheduling method, that is, when initial resource scheduling is performed before initial data transmission, the network device may send resource configuration information to multiple terminal devices in the terminal device group during initial resource scheduling. The resource configuration information includes indication information for indicating one time-domain resource unit initially scheduled by the network device and period information for indicating a preset period between every two time-domain resource units for subsequent scheduling. Then, the network device can indicate to the terminal device group through the resource configuration information that the first transmission resource includes multiple time domain resource units that can be used by the terminal device group, and every two adjacent time domain resource units are separated by a preset period.

S202, any terminal device in the terminal device group determines the second transmission resource used by the terminal device according to its identifier (index) and resource configuration information in the terminal device group. The available second transmission resources corresponding to different terminal devices are different, and the available second transmission resources corresponding to a single terminal device may be the same as or different from the first transmission resources.

Specifically, as shown in FIG. 2 , that is, UE1 may determine the second transmission resource used by UE1 according to the identification and resource configuration information of UE1 in the terminal equipment group; UE2 may determine the second transmission resource used by UE2 according to the identification and resource configuration information of UE2 in the terminal equipment group , to determine the second transmission resource used by the UE2; the UE3 may determine the second transmission resource used by the UE3 according to the identifier of the UE3 in the terminal equipment group and the resource configuration information. In a possible implementation manner, UE1, UE2, and UE3 have a second transmission resource that can be used by a terminal device, which is the first transmission resource, but the second transmission resources used by UE1, UE2, and UE3 are different.

The following describes in detail the manner in which the network device sends the resource configuration information in the dynamic scheduling manner. The network device may carry a first identifier in the resource configuration information, where the first identifier is used to indicate configuration information of the first transmission resource in the resource allocation list. The resource allocation list includes configuration information of multiple transmission resources.

Optionally, the network device may send the second DCI scrambled by the group RNTI on the first PDCCH, and the second DCI carries resource configuration information; each terminal device in the terminal device group parses the data added by the group RNTI by monitoring the first PDCCH. The second DCI that is disturbed can obtain the resource configuration information.

Optionally, the resource allocation list may be a pre-configured default table in each terminal device; or, the resource allocation list may also be configured by the network device to the terminal device group. Based on this, when the aforementioned RRC message on the first PDSCH carries the resource allocation list, any terminal device in the terminal device group can search for the configuration of the first transmission resource in the resource allocation list carried in the RRC message based on the resource configuration information information. When the RRC message on the first PDSCH does not carry the resource allocation list or the terminal device does not obtain the aforementioned RRC message, any terminal device in the terminal device group may search for the first transmission in the preconfigured default table based on the resource configuration information Configuration information for the resource.

Optionally, the resource allocation list includes a time-domain resource allocation list and/or a frequency-domain resource allocation list. Then the network device may use the first time domain resource assignment (Time donmain resource assignment, TDRA) field and/or the first frequency domain resource assignment (Frequency donmain resource assignment, FDRA) field as the aforementioned first identifier. Any terminal device in the terminal device group can search for the configuration information of the time domain resources included in the first transmission resource in the time domain resource allocation list based on the first time domain resource allocation field; any terminal device in the terminal device group can be based on the first time domain resource allocation. A frequency domain resource allocation field, which searches the frequency domain resource allocation list for configuration information of frequency domain resources included in the first transmission resource.

Optionally, the network device may configure resources for each terminal device in the terminal device group by carrying the resource allocation list in the RRC message sent by the first PDSCH, and by sending the first DCI indicating the first PDSCH on the first PDCCH. Assignment list. During specific implementation, the network device may use the resource allocation entity to encapsulate the configuration information of the transmission resource in the resource allocation list. For example, the resource allocation list includes multiple resource allocation entities, and each resource allocation entity includes configuration information of a transmission resource.

Optionally, the aforementioned configuration information of the transmission resource refers to a related parameter used to determine the time domain position and/or the frequency domain position of the transmission resource. For example, the network device carries the time domain resource allocation list (PUSCH-TimeDomainAllocationList) of the PUSCH in the RRC message. The time domain resource allocation list of the PUSCH includes multiple resource allocation entities, and each resource allocation entity includes configuration information of a transmission resource. The configuration information specifically includes an offset value of the time slot between the first PDCCH and the PUSCH, where the offset value is used to indicate the time slot occupied by the PUSCH; and a start symbol and a length (startSymbolAndLength), where the startSymbolAndLength is used to indicate the time slot occupied by the PUSCH The symbols that can be occupied by the transmission of uplink data in the time slot. Symbols that can be occupied by uplink data are transmitted in the time slot occupied by the PUSCH. Then, the terminal equipment group can determine the configuration information of the time domain resources that the terminal equipment group can use to send uplink data based on the time domain resource allocation list of the PUSCH.

In the embodiment of the present application, the network device performs resource configuration based on the terminal device group, which reduces the resources occupied by sending PUSCH scheduling information, such as the RRC signaling overhead and the resources occupied by the PDCCH, etc., thereby avoiding the impact on the transmission of other service data. In scenarios where the number of terminal devices is large and dense, such as video surveillance cameras on roads.

The manner in which each terminal device in the terminal device group determines the second transmission resource will be described below with respect to the dynamic scheduling manner.

Based on the resource configuration information sent by the network device in the dynamic scheduling mode, each terminal device in the terminal device group may offset or divide the first transmission resource indicated by the resource configuration information to determine the available second transmission resource. transfer resources. The first terminal device represents any terminal device in the terminal device group, and the determination of the second transmission resource used by the first terminal device in the dynamic scheduling mode may be implemented by referring to any one of the following modes 1 to 3.

Manner 1: The first terminal device may offset the first transmission resource according to the identifier of the first terminal device in the terminal device group and the first identifier to determine the second transmission resource used by the first terminal device.

Optionally, the first terminal device may first determine the second identifier according to the identifier of the first terminal device in the terminal device group and the first identifier, and then determine the configuration indicated by the second identifier in the resource allocation list. information, and determine the second transmission resource used by the first terminal device according to the configuration information indicated by the second identifier. That is, it can be understood that the second identifier is used to indicate the configuration information of the second transmission resource in the resource allocation list.

Illustratively, a schematic structural diagram of a resource offset is shown in FIG. 3 . Specifically, a time domain resource allocation list is shown. Each resource allocation entity in the time domain allocation list includes configuration information of a time domain resource, and different resource allocation entities use different time domain resource allocation TDRA fields for indication. As shown in FIG. 3 , the first TDRA field in the resource configuration information sent by the network device indicates the first resource allocation entity in the time domain resource allocation list, which means that the first resource allocation entity contains the configuration information of the first transmission resource . The terminal device group includes UE1, UE2, and UE3, and the first terminal device is any one of UE1, UE2, or UE3. The identifiers of UE1, UE2, and UE3 may be consecutively increasing numbers.

In an optional implementation, it is assumed that the first TDRA field occupies 4 bits (4 bits) and is "0000", the identifier of UE1 may be "0000", the identifier of UE2 is "0001", and the identifier of UE3 is "0010" . When the identifier of the first terminal device in the terminal device group is "0000", the first terminal device may determine that the second identifier includes the first TDRA field, and search for the first resource in the time domain resource allocation list based on the first TDRA field assigning entity, thereby determining that the second transmission resource used by the first terminal device includes the time domain resource corresponding to the first resource assigning entity. When the identifier of the first terminal device in the terminal device group is "0001", the first terminal device may determine that the second identifier includes the second TDRA field "0001", and search for the first terminal device in the time domain resource allocation list based on the second TDRA field. two resource allocation entities, thereby determining that the second transmission resource used by the first terminal device includes the time domain resource corresponding to the second resource allocation entity.

If the first terminal device is UE3, the first terminal device may divide and obtain a transmission resource unit numbered RGB4 in the first transmission resource.

Further, considering the situation that the terminal equipment fails to transmit uplink data and needs to be retransmitted; if multiple terminal equipments in the terminal equipment group use the same hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) process identifier such as HARQ process during initial transmission ID, the network device can determine the terminal device that fails to transmit based on the difference in the second transmission resources used by different terminal devices, and then independently schedule the uplink resources for the terminal device that fails to transmit. If each terminal device in the terminal device group uses different HARQ process IDs in combination with their identifiers in the terminal device group during initial transmission, the network device can determine the terminal device that fails to transmit based on the HARQ process ID of the terminal device, and then separately Perform uplink resource scheduling on the terminal equipment that fails to transmit.

In addition, optionally, the network device may carry the identifier of the designated terminal device in the terminal device group in the resource configuration information to indicate that only the designated terminal device is allowed to use the first transmission resource.

The manner in which the network device sends the resource configuration information in the semi-persistent scheduling manner will be described in detail below.

For ease of understanding, the following table 1 also shows the manner of consecutively numbering multiple time-domain resource units that can be scheduled: N represents the number of time-domain resource units, and N is a natural number starting from 0. For example, when N is 0, it indicates a time-domain resource unit initially scheduled by the network device; when N is 1, it indicates the second schedulable time-domain resource unit; when N is 2, it indicates the third schedulable time-domain resource unit; and so on.

The first terminal device represents any terminal device in the terminal device group. In the semi-persistent scheduling mode, the first terminal device determines the second transmission resource used by the first terminal device and may be implemented with reference to the following modes 1 to 4.

Manner 1: The network device may include, in the resource configuration information, the number of terminal devices in the terminal device group and/or the number of the time domain resource units that any terminal device in the terminal device group can use continuously. Then, the first terminal device can be divided into the following three cases according to the resource configuration information including different contents, and determine the second transmission resource used by the first terminal device.

The first case: the resource configuration information includes the number of terminal devices in the terminal device group, but does not include the number of the time domain resource units that can be continuously used by any terminal device in the terminal device group. The first terminal device is pre-configured with the default quantity value of its continuous use time domain resource units, then the first terminal device can use the identifier of the first terminal device in the terminal device group, the aforementioned default The number of terminal devices in the terminal device group determines the second transmission resource used by the first terminal device.

Case 2: The resource configuration information includes the number of the time domain resource units that can be used continuously by any terminal device in the terminal device group, but does not include the number of terminal devices in the terminal device group. Then, the first terminal device can determine the number of terminal devices in the terminal device group according to the RRC message from the network device, where the RRC message carries the identifier of each terminal device in the terminal device group. Furthermore, the first terminal device can use the identifier of the first terminal device in the terminal device group, the number of terminal devices in the terminal device group, and the time domain that any terminal device in the terminal device group can use continuously. The number of resource units determines the second transmission resource used by the first terminal device.

Case 3: The resource configuration information includes the number of the time domain resource units that can be used continuously by any terminal device in the terminal device group, and the number of terminal devices in the terminal device group. Then, the first terminal device determines the second transmission resource used by the first terminal device according to the identifier of the first terminal device in the terminal device group and the quantity included in the foregoing resource configuration information.

As shown in Figure 6, a schematic diagram of time domain resource division is shown. UE1, UE2, and UE3 follow the cyclic sequence of UE1->UE2->UE3->UE1. First, UE1 continuously uses two time-domain resource units, and UE2 continuously uses UE1. After using 2 time-domain resource units, and then using 2 time-domain resource units continuously, UE3 uses 2 time-domain resource units continuously after UE2 uses 2 time-domain resource units continuously, and then when UE3 uses 2 time-domain resource units continuously After the domain water resource unit, return to UE1 to continuously use 2 time domain resource units.

Method 2: The network device may include the number of terminal devices in the terminal device group and/or the first duration in the resource configuration information, where the first duration is used to indicate the time when any terminal device in the terminal device group can be used continuously Domain Resource Unit. Then, the first terminal device can be divided into the following three cases according to the resource configuration information including different contents, and determine the second transmission resource used by the first terminal device.

The first case: the resource configuration information includes the number of terminal devices in the terminal device group, but does not include the first duration; the first terminal device is preconfigured with the default duration of its continuous use time domain resource unit, then the first The terminal device may determine the second transmission resource used by the first terminal device according to the identifier of the first terminal device in the terminal device group, the aforementioned default duration, and the number of terminal devices in the terminal device group.

Case 2: The resource configuration information includes the first duration, but does not include the number of terminal devices in the terminal device group. Then, the first terminal device can determine the number of terminal devices in the terminal device group according to the RRC message from the network device, where the RRC message carries the identifier of each terminal device in the terminal device group. Furthermore, the first terminal device may determine the second transmission resource used by the first terminal device according to the identifier of the first terminal device in the terminal device group, the number of terminal devices in the terminal device group and the first duration.

Case 3: The resource configuration information includes the first duration and the number of terminal devices in the terminal device group. Then the first terminal device determines the first terminal according to the identifier of the first terminal device in the terminal device group, the first duration included in the foregoing resource configuration information, and the number of terminal devices in the terminal device group. The second transmission resource used by the device.

Specifically, in the above three cases, the first terminal device may determine the time period during which the first terminal device uses the first duration according to the identifier of the first terminal device in the terminal device group and the number of devices in the terminal device group. Indicates the order of time domain resource units. Furthermore, the first terminal device may determine the second transmission resource used by the first terminal device among the first transmission resources according to the sequence.

Exemplarily, it is assumed that the terminal equipment group includes UE1, UE2, and UE3, that is, the number of terminal equipments in the terminal equipment group is 3, and the foregoing first duration includes 2 time domain resource units. As shown in Figure 7, a schematic diagram of time domain resource division is shown. UE1, UE2, and UE3 follow the cyclic sequence of UE1->UE2->UE3->UE1. First, UE1 continuously uses two time-domain resource units included in the first duration. , UE2 continuously uses the 2 time domain resource units included in the first duration after UE1 continuously uses the 2 time domain resource units included in the first duration, and UE3 continuously uses the 2 time domain resource units included in the first duration at UE2 After that, the 2 time-domain resource units included in the first duration are used continuously, and after UE3 continuously uses the 2 time-domain water resources units included in the first duration, it returns to UE1's continuous use of the 2 time-domain resources included in the first duration resource unit.

Mode 3: The resource configuration information of the network device includes a hybrid automatic repeat request process identifier (HARQ process ID) corresponding to each terminal device in the terminal device group. The first terminal device may determine the second transmission resource used by the first terminal device according to the identifier of the first terminal device in the terminal device group and the HARQ process identifier corresponding to the first terminal device.

Optionally, the network device may include, in the resource configuration information, the identifier of each terminal device in the terminal device group and the HARQ process ID associated with each terminal device identifier. Then, the first terminal device may first look up the HARQ process ID associated with the identification of the first terminal device from the resource configuration information to determine the HARQ process ID corresponding to the first terminal device. Furthermore, the first terminal device can determine the second transmission resource used by the first terminal device according to the HARQ process ID corresponding to the first terminal device, and the second transmission resource includes at least one time domain resource unit, and the time of the at least one time domain resource unit. The domain position depends on the HARQ process ID corresponding to the first terminal device, and the number of time domain resource units included in the second transmission resource depends on the number of HARQ process IDs corresponding to the first terminal device.

Specifically, the network device can determine multiple HARQ process IDs based on the following calculation formula, and configure different HARQ process IDs to different terminal devices through resource configuration information, that is, configure different transmission resources to different terminal devices.

HARQ Process ID=[floor(CURRENT_symbol/periodicity)]modulo nrofHARQ-Processes;

CURRENT_symbol=(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot);

Among them, floor represents the rounding down operation, modulo represents the modulo operation; CURRENT_symbol represents the conversion symbol (symbol) based on the starting time domain position of the time domain resource unit, and the conversion is obtained before the starting time domain position of the aforementioned time domain resource unit. numberOfSlotsPerFrame refers to the number of consecutive time slots in each frame; numberOfSymbolsPerSlot refers to the number of consecutive symbols in each time slot.

Exemplarily, referring to a semi-persistent scheduling resource configuration method shown in Table 2 below, the number of HARQ processes (nrofHARQ-Process) is 16, the subcarrier spacing (SCS) is 15Khz, and each time slot is 15Khz. It includes 14 symbols (numbered 0 to D), periodicity is 14 symbols, timeDomainOffset is 1 time slot, S=4, L=6 as an example, a time domain resource unit initially scheduled by the network device includes the system frame number SFN In the frame numbered 5, there are 6 symbols numbered 4-9 in the time slot numbered 1. The difference between the start symbol of any subsequent schedulable time-domain resource unit and the start symbol of the previous time-domain resource unit is one cycle, that is, 14 symbols, and any time-domain resource unit includes 6 symbols; The time-domain resource units include 6 symbols numbered 4-9 in the time slot numbered 2 in the frame of the system frame number 5. For ease of understanding, the following table 1 also shows the manner of consecutively numbering multiple time-domain resource units that can be scheduled: N represents the number of time-domain resource units, and N is a natural number starting from 0. For example, when N is 0, it indicates a time-domain resource unit initially scheduled by the network device; when N is 1, it indicates the second schedulable time-domain resource unit; when N is 2, it indicates the third schedulable time-domain resource unit; and so on.

Furthermore, based on the above calculation method, the HARQ Process ID corresponding to the time domain resource unit whose sequence number is N in the system frame number SFN=5 can be determined. Referring to the parameters in Table 3 below, it is concluded that the HARQ Process ID corresponding to the time domain resource unit with sequence number 0 in SFN=5 is 3; the HARQ Process ID corresponding to the time domain resource unit with sequence number 1 in SFN=5 is 4; the HARQ Process ID corresponding to the time domain resource unit with sequence number 2 in SFN=5 is 5.
