Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The invention provides a kind of method of scheduling user's set, be applicable to the mobile communications network under multi-access point framework, need to be provided with multiple base station or access point under this mobile communications network, and between neighboring access point, adjacent base station, between adjacent access point and base station requirement can communicate mutually.
Based on said system framework, embodiments provide a kind of method of scheduling user's set, be mainly used in uplink communication and the downlink communication of management user device.
Flow process is downlink communication scheduling flow as shown in Figure 1, specifically comprises:
101, the multi-upstream access point of descending access point determination subscriber equipment.
Wherein, descending access point for current for described subscriber equipment provides access point or the base station of downstream service and upstream service simultaneously.Under there are quality problems or need to carry out the situations such as system load balancing in the up channel of subscriber equipment and descending access point, the uplink service of this subscriber equipment is all likely needed to be separated with downlink business, two access points or base station is allowed to manage respectively, in embodiments of the present invention, the management of downlink business is still managed by descending access point, and uplink service then needs to reselect new multi-upstream access point and manages.
It should be noted that in addition, the embodiment of the present invention only relates to the constant situation of descending access point, if when quality problems appear in the down channel of subscriber equipment and descending access point, then follows prior art conventional means, for user reselects new descending access point.And after redefining new descending access point, complete every flow process that the embodiment of the present invention provides.
About the selection embodiment of the present invention of multi-upstream access point provides a kind of method at this, comprise: described descending access point, according to the current uplink signal-channel quality of access point loading condition, described subscriber equipment and uplink service information, judges whether to need the up-downgoing business of described subscriber equipment to be separated; Need if determine to be separated, then described descending access point notifies that the channel quality between described subscriber equipment and neighboring access point measured by described subscriber equipment, and sends request the signaling of carrying uplink service to neighboring access point; Described descending access point is defined as described multi-upstream access point by one that agrees in the neighboring access point of the described subscriber equipment uplink service of carrying.
In addition, also it should be added that, conveniently many base stations are to the management of same subscriber equipment, when uplink service is separated with downlink business, descending access point needs for a new cell ID redistributed by subscriber equipment, and notifies multi-upstream access point and subscriber equipment.Such subscriber equipment just can carry out uplink communication according to this cell ID and multi-upstream access point.
102, described descending access point receives the subscriber equipment feedback information that multi-upstream access point sends, and described subscriber equipment feedback information is sent to multi-upstream access point by subscriber equipment, comprises upstream data, uplink channel information and descending channel information.
Wherein, upstream data generally can comprise PUSCH(Physical Uplink Shared Channel, Physical Uplink Shared Channel) the middle data transmitted, uplink channel information generally comprises the signaling relevant to uplink communication, as at PUCCH(Physical Uplink Control CHannel, physical uplink control channel) the middle SR(scheduling request transmitted, dispatch request), at PUSCH(Physical Uplink SharedChannel, Physical Uplink Shared Channel) the middle BSR(Buffer Status Report transmitted, Buffer Status Report) and power report etc., descending channel information generally can comprise the signaling relevant to downlink communication, as descending channel feedback, downlink data ACK/NACK(receive/does not receive) etc.Above Information Availability is dispatched in access point or base station the up-downgoing of subscriber equipment.
103, described descending access point is according to described subscriber equipment feedback information, carries out descending scheduling to described user input device.
The method of the scheduling user's set that the embodiment of the present invention provides, by the uplink information using optimum multi-upstream access point to obtain subscriber equipment, and this information is forwarded to descending access point descending access point can be dispatched according to the downlink communication of subscriber equipment feedback information to subscriber equipment accurately, uplink scheduling has then been come by the multi-upstream access point of optimum, can solve in prior art cause because up-downgoing channel quality is unbalanced cannot provide up-downgoing scheduling accurately for subscriber equipment, up-downgoing covers the problems such as unbalanced, presence of intercell interference.
Relevant to the descending scheduling of above-mentioned subscriber equipment, the embodiment of the present invention also provides corresponding uplink scheduling flow process, as shown in Figure 2, comprising:
201, multi-upstream access point receives the subscriber equipment feedback information that subscriber equipment sends, and described subscriber equipment feedback information comprises upstream data, uplink channel information and descending channel information; Wherein, described multi-upstream access point is the optimum access point of the uplink communication of subscriber equipment.
202, described multi-upstream access point is according to described subscriber equipment feedback information, carries out uplink scheduling to described user input device.
The method of the scheduling user's set that the embodiment of the present invention provides, by the uplink information using optimum multi-upstream access point to obtain subscriber equipment, and the uplink scheduling completed subscriber equipment, can solve in prior art cause because up-downgoing channel quality is unbalanced cannot provide up-downgoing scheduling accurately for subscriber equipment, up-downgoing covers the problems such as unbalanced, presence of intercell interference.
In conjunction with the above-mentioned description to technical solution of the present invention, the embodiment of the present invention provides following two kinds of concrete implementations for the realization of step 103, respectively as shown in Figure 3 and Figure 4.
Method flow is as shown in Figure 3 applied to the rate of information throughput between described descending access point and described multi-upstream access point higher than under the condition of predetermined threshold value, with this understanding, transmission delay between multi-upstream access point and descending access point can be very low, therefore, the information being forwarded to descending access point by multi-upstream access point can be thought real-time, and descending like this access point just can directly use the information got to carry out subsequent treatment.
Wherein, the setting principle of predetermined threshold value is the real-time of guarantee information transmission, can set according to the empirical value of the transmission delay between networking configuration and base station access point.
The method flow process specifically comprises:
A1031, described descending access point carry out demodulation to described descending channel information.
A1032, described descending access point carry out descending scheduling according to the descending channel information after demodulation to described user input device.
Above flow process can think that descending access point directly receives user input device feedack, and its specific implementation flow process can follow the conventional flow process of prior art, and the embodiment of the present invention does not do too much description to this.
Method flow is as shown in Figure 4 applied to the rate of information throughput between described descending access point and described multi-upstream access point not higher than under the condition of predetermined threshold value, with this understanding, transmission delay between multi-upstream access point and descending access point can be higher, therefore, the information being forwarded to descending access point by multi-upstream access point cannot be thought real-time, and descending like this access point just needs to do certain delay process when the information using multi-upstream access point to forward.
The method flow process specifically comprises:
B1031, described descending access point carry out demodulation in t to described descending channel information, obtain the first downlink channel control signaling, and receiving the second downlink channel control signaling of described multi-upstream access point transmission, described second downlink channel control signaling carries out demodulation in t-Δ t to described descending channel information by described multi-upstream access point and obtains.
Wherein, t is described descending access point carries out demodulation moment to described descending channel information, and Δ t is for by the time of transmitting described subscriber equipment feedback information between described multi-upstream access point and described descending access point and spending.
The subscriber equipment feedback information received due to multi-upstream access point is real-time, therefore its demodulation result can be more accurate, now, the demodulation result that multi-upstream access point just can be allowed to make with regard to self is sent to descending access point and carries out reference for descending access point, but the transmission delay between multi-upstream access point and descending access point, the demodulating information sent by multi-upstream access point so just causing descending access point to receive in t is actual is the demodulation result of multi-upstream access point in t-Δ t, therefore this execution mode of the present invention will adjust the demodulation result of descending access point in t in conjunction with the demodulation difference between t-Δ t up-downgoing access point.
B1032, the 3rd downlink channel control signaling obtained in the demodulation of t-Δ t stored according to described second downlink channel control signaling and described descending access point, described first downlink channel control signaling is adjusted, and according to the first downlink channel control signaling after adjustment, descending scheduling is carried out to described user input device.
The principle of this adjustment uses in t-Δ t exactly, second downlink channel control signaling and described descending access point store the difference between the 3rd downlink channel control signaling, namely the difference between the actual demodulation result that the correct demodulation result completed in t-Δ t at multi-upstream access point and descending access point complete in t-Δ t, the first downlink channel control signaling that descending access point is made in t is calibrated, to ensure the first downlink channel control signaling more convergence channel control signal accurately after adjusting.
And the difference between the actual demodulation result that completes in t-Δ t of the correct demodulation result that completes in t-Δ t of multi-upstream access point and descending access point can be embodied in the difference of channel quality information, the difference of scheduling resource etc.
Above two kinds of methods provide different implementation method under different delay for step 103 between base station or access point, and the communication issue existed when having taken into full account that networking is disposed, can provide the management precision of up-downgoing service detach effectively.

Wherein, descending access point is when for described user equipment allocation uplink transmission resource, be not will carry out uplink transmission resource according to the information such as up channel and upstream control signaling, but dispatched by multi-upstream access point, resource A can be expressed as, but user directly can not get this resource information from multi-upstream access point, therefore need to inform which part resource the resource A that user specifically uses is on earth by descending access point, this part informs that signaling is transmitted in downlink communication, and the resource B that resource A specifically takies is only that descending access point determines.That is, descending access point is described user equipment allocation uplink transmission resource according to described uplink scheduling information, exactly resource A is converted to the process of resource B.This Resourse Distribute flow process be applicable to the embodiment of the present invention follow-up provide all about descending access point be the flow process of described user equipment allocation uplink transmission resource according to described uplink scheduling information.
This implementation method is the distribution being completed scheduling resource by multi-upstream access point, but because the downlink communication quality between multi-upstream access point and subscriber equipment is difficult to be guaranteed, therefore, the good descending access point of down channel quality can be forwarded to be sent to subscriber equipment in the good situation of time delay, ensure the uplink of subscriber equipment.
