Optionally, the mode that trunking obtains resource pool includes but is not limited to following several implementations:

One of possible implementation: base station or network side equipment are to the configuration information of trunking transmission resource pool, and trunking is according to the configuration information of the resource pool acquisition information such as resource pool time frequency position and/or resource pool size.Specifically, base station can send the configuration information of resource pool by the control information transmitted on cellular link to trunking.

Alternatively possible implementation: trunking obtains the configuration information of resource pool by way of pre-configuration；Such as it is provided by agreement, or be pre-configured with according to the license of different regions wireless management mechanism and obtained by network side equipment.

S202: trunking sends the first control information in first resource.

Trunking can be according to the remote equipment dispatched by trunking determining the case where business and resource.

Wherein, the first control information is used to indicate the information (also referred to as whether remote equipment is by the information of trunking scheduling) for the remote equipment dispatched by trunking and the location information of the corresponding Secondary resource of scheduled remote equipment.

It is assumed that trunking dispatches 3 remote equipments, then its 3 remote equipment of instruction in the first control information is scheduled, and 3 remote equipments are respectively remote equipment 1, remote equipment 2 and remote equipment 4；The first resource of transmission the first control information, and the Secondary resource of the second control information of remote equipment 1 is transmitted, the Secondary resource of the second control information of remote equipment 2 is transmitted, the Secondary resource that the second of transmission remote equipment 2 controls information is as shown in Figure 3.Wherein, the first control information can periodically be sent.

In a kind of possible implementation, it can be carried in the corresponding Bypass Control information SCI of the first control information by the information of remote equipment and the location information of the corresponding Secondary resource of scheduled remote equipment that trunking is dispatched.It is that each remote equipment dispatched by trunking defines two domains in SCI, as shown in Figure 4, one domain is used to indicate the information for the remote equipment dispatched by trunking, such as: the information of remote equipment can be the local ident (Local ID) or interim ID of remote equipment, a remote equipment is identified with N-bit, can at most identify 2^NA remote equipment.Pass through the ID of 3 bit indication remote equipments, respectively C7, C6 and C5 in Fig. 4, can be used for identifying the information of 8 remote equipments.Another domain is used to indicate the location information of Secondary resource, in Fig. 4 by taking 5 bits as an example, respectively C4, C3, C2, C1 and C0.

In alternatively possible implementation, it is carried at by the information of remote equipment and the location information of Secondary resource that trunking is dispatched in the media access control control unit (Media Access Control Control Element, MAC CE) of the corresponding data of the first control information.

This mode is similar with mode shown in Fig. 4, the difference is that being that the remote equipment that each trunking is dispatched defines two domains in SCI in Fig. 4, and the remote equipment that this mode is each trunking scheduling in the MAC CE of the corresponding data of the first control information defines two domains, the definition mode in two domains is similar with Fig. 4, and details are not described herein again.

In another possible implementation, it is carried in the corresponding Bypass Control information SCI of the first control information by the information for the remote equipment that trunking is dispatched, the location information of the Secondary resource is carried in the MAC CE of the corresponding data of the first control information.As shown in figure 5, the corresponding SCI instruction of the first control information is set by relaying The information of the remote equipment of standby scheduling can indicate by the mode of bit map (bitmap, alternatively referred to as bitmap), the bit in bitmap corresponding with the associated each remote equipment of trunking.Indicate whether the associated remote equipment of trunking is scheduled in Fig. 5 by the bitmap of 8 bits, value by the way that corresponding bit position is arranged indicates whether corresponding remote equipment is scheduled, such as: if 1 indicates scheduled, 0 indicates not to be scheduled, if some remote equipment is scheduled, the value that the corresponding bit of the remote equipment is arranged is 1.It indicates not to be scheduled if 0 indicates scheduled, 1, if some remote equipment is scheduled, the value that the corresponding bit of the remote equipment is arranged is 0.In fig. 5, it is assumed that the value of bit is that 1 expression is scheduled, then remote equipment 1, remote equipment 2 and remote equipment 4 are scheduled, remaining remote equipment is not scheduled.The location information of Secondary resource is carried in the MAC CE of the corresponding data of first control information, as shown in Figure 5.Remote equipment first detects the corresponding SCI of the first control equipment, determines whether itself is scheduled, if scheduled, the MAC CE of the corresponding data of detection the first control information, to obtain the location information of Secondary resource.In mode shown in Fig. 5, the remote equipment being only scheduled needs to demodulate the MAC CE of the corresponding data of the first control information.

S203: trunking sends the second control information of the remote equipment dispatched by trunking in Secondary resource according to the location information of determining Secondary resource.

It wherein, include scheduling information in the second control information.

Optionally, trunking can also scramble its corresponding second control information by the relevant information of scheduled remote equipment before sending the second control information of scheduled remote equipment.Such as: relevant information can be identification information, such as can be Global ID or Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (CellRadioNetworkTemporaryIdentifier, C-RNTI), layer 2ID etc.；Such as: remote equipment 1 is dispatched by trunking, then the second control information of remote equipment 1 is scrambled by the identification information such as Global ID of remote equipment 1, so that remote equipment 1 correctly descrambles the second control information, and other remote equipments cannot correctly descramble the second control information of remote equipment 1.

It optionally, can also include second indication information in the second control information, second indication information is used to indicate the control information for the transfer resource that the second control information is dispatching of relays equipment；Alternatively, the second control information is to dispatch the control information of the transfer resource of remote equipment.I.e. second indication information is used to indicate the second control information and still bypasses downlink (Sidelink DL) control information for bypass uplink (Sidelink UL) control information.Second indication information can indicate by 1 bit, such as: 0 indicates bypass down link control information, and 1 indicates bypass uplink control information.Bypass downlink refers to trunking to the link of remote equipment；Bypass uplink refers to remote equipment to the link of trunking.

Correspondingly, remote equipment receives the first control information in first resource, and according to the location information of Secondary resource, determines Secondary resource, receives the second control information in Secondary resource.
