Optionally, the first user equipment obtains each second user equipment in multiple second user equipment in preset range
The acquisition modes of orthogonal sequence corresponding to preselected uplink transmission resource can have following two optional embodiments：
In the first optional embodiment, cell coverage area is smaller, and specific network system architecture figure can be as
Shown in Fig. 2, all user equipmenies can carry out information resources application information interaction by D2D connections in cell coverage area,
Then the method for the orthogonal sequence of the first user equipment acquisition second user equipment can include following two steps：
Step 1, first user equipment establish and cell preset range in multiple second user equipment between number
According to connection；
Specific optional, second user equipment is in cell in addition to the first user equipment and preliminery application uplink transmission resource
User equipment, second user equipment is according to own service demand application uplink transmission resource, and the sequence group defined in system
Orthogonal sequence corresponding to interior selection.
First user equipment establish and cell preset range in multiple second user equipment between data connect, can be with
It is D2D connections, all user equipmenies (including the first user equipment and second user equipment) are by selected sequence in listening period
The first time slot mapping on default D2D running time-frequency resources.
Step 2, based on the default running time-frequency resource of data connection, first user equipment obtains the multiple the

It is specific optional, preset because the orthogonal sequence of itself is mapped in D2D by all user equipmenies on running time-frequency resource,
As shown in fig. 6, be a kind of default time-frequency resource maps figure of D2D data connection provided in an embodiment of the present invention, as illustrated,
CTU and code book CB maps to the default running time-frequency resource of D2D connections, therefore institute in the uplink transmission resource of all user equipmenies
There is user equipment to be based on the default running time-frequency resource, obtain the orthogonal sequence of other user equipmenies.
In the embodiment of the present invention, the first user equipment can based on the data connect default running time-frequency resource, obtain it is other
Orthogonal sequence in multiple second user equipment corresponding to the preselected uplink transmission resource of each second user equipment.
In second of optional embodiment, when MPS process is larger, region-wide orthogonal sequence information can not be met
Interaction, then the present embodiment presses some cooperative groups of region division to intra-cell users, incite somebody to action this by management user equipment (Master UE)
Resource bid state in cooperative groups interacts through base station and remaining cooperative groups in cell, so as to realize in a wider context
The resource bid interaction of user collaboration.Specific network architecture diagram is as shown in figure 3, the intra-cell users equipment is divided into two associations
Work group region.Each cooperative groups region includes a Master UE, as shown in figure 3, color is most deep in a cooperative groups region
User equipment be Master UE, in embodiments of the present invention by the first user equipment be Master UE exemplified by illustrated
Illustrate, certain first user equipment is that Master UE do not form limitation of the invention, and the first user equipment may not be
Master UE, the present invention are not construed as limiting.D2D connections are established between user equipment in each cooperative groups region.
First user equipment obtains the acquisition side of the orthogonal sequence corresponding to the preselected uplink transmission resource of the second equipment
Formula comprises the following steps two steps：
Step 1, the data between user equipment in the first user equipment foundation and the target cooperative groups region
Connection, and the user equipment that the default running time-frequency resource based on data connection is obtained in the target cooperative groups region is pre-
Orthogonal sequence corresponding to the uplink transmission resource of selection；
It is specific optional, the D2D connections between user equipment in the foundation of the first user equipment and target cooperative groups region,
And the default running time-frequency resource based on the D2D connections obtains the uplink money that all user equipmenies are preselected in the cooperative groups region
Orthogonal sequence corresponding to source.
It should be noted that when between the user equipment in the foundation of the first user equipment and the target cooperative groups region
After D2D connections, the orthogonal sequence of itself is mapped to the pre- of D2D connections by all user equipmenies in the first time slot of listening period
If on running time-frequency resource, therefore all user equipmenies in the target cooperative groups region can the default time-frequency based on the D2D connections
Resource obtains the orthogonal sequence that other user equipmenies are mapped.
Step 2, first user equipment, which receives, removes target association in the multiple cooperative groups region of base station forwarding
All user equipment pre-selections in the cooperative groups region that user equipment uploads are managed in each cooperative groups region outside work group region
The orthogonal sequence corresponding to uplink transmission resource selected.
It is specific optional, when the first user equipment needs to obtain the orthogonal sequence of user equipment in other cooperative groups regions
When, the data that the first user equipment is established between base station connect, and receive its other cooperative groups region forwarded from base station
The orthogonal sequence of each user equipment in the cooperative groups region that interior management user equipment uploads.
It should be noted that include a management user equipment in each cooperative groups region, and each cooperative groups area
Orthogonal sequence interactive mode in domain is a cooperative groups region with the interactive mode of orthogonal sequence in target cooperative groups region

Identical uplink transmission resource that the result non-zero of calculation has been existing other users equipment application, can not determine can not be at this
Target uplink transmission resource carries out transmitting uplink data, as shown in figure 4, identical time domain, frequency domain and code book can include 6
Pilot signal, it is the transmitting uplink data that can carry 6 user equipmenies, therefore the embodiment of the present invention can be according to actual general
Rate collision situation, budget threshold value is set, if the result of related operation is less than predetermined threshold value, the determination of the first user equipment can be
Target uplink transmission resource carries out transmitting uplink data (select the probability of same pilot signal smaller), if related operation
Result be more than predetermined threshold value, then the first user equipment can not target uplink transmission resource carry out transmitting uplink data (select
The probability for selecting same pilot signal is bigger).
If it should be noted that the first user equipment can not target uplink transmission resource carry out transmitting uplink data,
Continue to initiate resource selection again in next listening period.
