Gathering corresponding different PRACH resources may include：Different SR gathers the time-frequency of corresponding PRACH
It is different that the different and/or different SR of resource gathers corresponding random access sequence.
Like this, different types of Equations of The Second Kind node, the Equations of The Second Kind node of different working modes, not of the same trade or business
The Equations of The Second Kind node of service type or the Equations of The Second Kind node of different service types combination, will be gathered using difference SR
Corresponding PRACH resources carry out Stochastic accessing, it is to avoid same type of Equations of The Second Kind node application scheduling of resource
Excessively, other kinds of Equations of The Second Kind node is caused to ask the phenomenon dispatched at all.
Belong to the SR resources difference of the Equations of The Second Kind node configuration in same SR set.Like this, each
The SR resources of Equations of The Second Kind node are different, and each Equations of The Second Kind node sends tune using its SR resources are distributed to
Degree demand signalling.
Certainly, the SR resources belonged in same SR set can be randomly choosed for the Equations of The Second Kind node.I.e.
One or more SR resources are configured with a SR set, belong to the Equations of The Second Kind section in same SR set
Point, randomly chooses SR resources therein and sends scheduling request signaling.
It is different that different SR gathers corresponding dispatching priority；Wherein, the dispatching priority is described the
One class node responds the priority of the SR information that the Equations of The Second Kind node sends.Generally dispatching priority is higher,
The SR information that then the faster response Equations of The Second Kind node is sent by first kind node.The SR set and institute
The mapping relations for stating dispatching priority can be configured by the first kind node, or communication standard acquiescence
Configuration；The generation type of the mapping relations between the SR set and dispatching priority has various, not office

In step s 110, the SR resources of SR information will be sent according to secondary nodal point, will be determined corresponding
SR gathers, and determines corresponding dispatching priority according to SR set, according to dispatching priority response
SR information, if dispatching priority is high, the first kind node will respond the SR information faster, if
Dispatching priority is low, and the possible first kind node will likely respond the SR information after a while.
Like this, the first kind node according to dispatching priority, will have the response of the priority SR letters
Breath, is capable of the SR information of possible preecedence requirement quick response, while being capable of the SR letters of relatively slow response
Breath is just responded after a while again, it is clear that such that first kind node more has the response of the conditioning SR information,
Reduce because the randomness of response causes the phenomenon of users' satisfaction degree difference.
The corresponding SR response times window length of different dispatching priorities is different, and priority is higher, the SR
Response time window length is shorter；Step S130 may include：Ring in the corresponding SR of the dispatching priority

Step S140 specifically may include：Determined based on the dispatching priority send the confirmation and
Transmission delay between the schedule information；After the confirmation is sent, the transmission delay it
After send the schedule information.
For example, the confirmation and the schedule information are required for sending in the SR response times window,
If first sending the confirmation, according to during the transmission of the SR response times window and the confirmation
Carve, it may be determined that go out after how long the confirmation is sent, it is necessary to send the confirmation, this
Permission time interval between the individual confirmation and the schedule information is the maximum of the transmission delay
Value.The last first kind node needs to send the schedule information in the transmission delay, to enter in time
The response of row SR information and scheduling of resource, it is to avoid the access of request again of Equations of The Second Kind node and sending out for SR information
The phenomenon of congestion is accessed caused by sending.
Methods described also includes：
Sending to the Equations of The Second Kind node includes the Delay of the transmission delay.It is described in the present embodiment
The forward delay interval is directly informed Equations of The Second Kind node by the delayed data by first kind node, such second

When after receive the schedule information.
It is described that the Delay for including the transmission delay is sent to the Equations of The Second Kind node, including：
The Delay and the confirmation are carried out into combined coding, combined coding information is formed；
The combined coding information is sent to the Equations of The Second Kind node.
The confirmation and delayed data are carried out into combined coding in the present embodiment, one can reduce
The expense of the signaling of interaction between one class node and Equations of The Second Kind node, while by sending combined coding information,
Confirmation and delayed data can be disposably sent, is reduced between first kind node and Equations of The Second Kind node
Information interaction amount, reduces the power consumption of Equations of The Second Kind node.
Combined coding herein, such as represent confirmation using two 2 bits, this 2 bits " 00 "
Expression does not receive SR information；" 01 " represents the confirmation, and transmission delay is 1 quantization unit；
" 10 " represent the confirmation, and transmission delay is 2 quantization units；" 11 " represent the confirmation letter
Breath, and transmission delay is 3 quantization units.
As shown in figure 3, step S140 also may particularly include：
Step S141：After the confirmation is sent, the first scheduling letter is sent in the forward delay interval
Breath；First schedule information includes the Dispatch by appointment moment；
Step S142：When reaching at the Dispatch by appointment moment, the second schedule information is sent.
The schedule information may include the first schedule information and the second schedule information in the present embodiment.When first
Class node is current more busy, it is impossible to carry out scheduling of resource immediately, but must be in the SR response times
In window, the response SR information, completes the response of SR information, and this when is in order to avoid first kind node
Load is further exacerbated by, and the first kind node will first send described in the SR response times window
One schedule information.Include the Dispatch by appointment moment in first schedule information.So, when the Equations of The Second Kind
After node receives first schedule information, will know that in Dispatch by appointment reception to receive second
Schedule information.The first kind node determined according to situations such as itself load the Dispatch by appointment moment it
Afterwards, second schedule information will be sent at the Dispatch by appointment moment.So, the Equations of The Second Kind node is just
Second schedule information can successfully be received at the Dispatch by appointment moment, be wrapped in second schedule information
Parameter of scheduling of resource etc. is included, the response to SR information is this completes.
In the present embodiment when the confirmation is sent, individually the confirmation can be sent to often
One Equations of The Second Kind node, it is also possible to which the confirmation for being sent to multiple Equations of The Second Kind nodes is carried on into same message
In be sent to Equations of The Second Kind node.For example, the mode of use information polymerization, by the confirmation of multiple Equations of The Second Kind nodes
Information fusion is sent in same message, so reduces the transmission times of first kind nodal information.
