Fig. 1 is refer to, the uplink and downlink timeslot method of adjustment of tdd communication systems provided in an embodiment of the present invention is being answered During for the centralized management equipment, comprise the following steps：
Step 11, centralized management equipment judges whether self-interference cluster meets default time slot ratio regularization condition.
Here, the default time slot ratio regularization condition can be set as needed.For example, time slot ratio adjusts item Part can receive the time slot ratio adjustment order from webmaster, for example, when the uplink and downlink for wishing some self-interference cluster of adjustment During time slot ratio, adjustment order can be manually entered, and specifies the target configuration information of uplink and downlink timeslot adjustment.In another example when Gap ratio regularization condition can also be carries out the number of cells or small that some direction adjusts time slot ratio for request in self-interference cluster Area's ratio exceeds corresponding thresholding, at this point, the time slot ratio adjust request that centralized management equipment can be sent according to each base station, The number of cells of expectation adjustment direction of the statistics with identical uplink and downlink timeslot ratio, according to the number of cells or described small Whether ratio of area's quantity in the multiple cell exceeds corresponding thresholding, when judging whether the self-interference cluster meets default Gap ratio regularization condition.
Here, the time slot ratio adjust request can also carry to represent having for the time slot ratio adjust request The second indication information of time is imitated, at this point, the further current time of the centralized management equipment and the adjustment of each time slot ratio please The effective time asked determines currently valid time slot ratio adjust request, and then counts described with identical uplink and downlink timeslot The number of cells of the expectation adjustment direction of ratio.
Step 12, when meeting the time slot ratio regularization condition, the centralized management equipment determines uplink and downlink timeslot tune Whole target configuration information, the corresponding base station of each cell into the self-interference cluster send one and carry uplink and downlink timeslot tune The time slot ratio adjustment order of whole target configuration information.
Here, exceed in number of cells/ratio of the expectation adjustment direction with identical uplink and downlink timeslot ratio It, can be according to the expectation adjustment direction of these cells, to be adjusted to current time slot ratio, for example, working as during corresponding thresholding It is that when increasing ascending resource and reducing downlink resource, can suitably increase the quantity of ascending time slot/subframe, subtract it is expected adjustment direction The quantity of few descending time slot/subframe；In another example when it is to increase downlink resource and reduce ascending resource it is expected adjustment direction, it can Suitably to increase the quantity of descending time slot/subframe, the quantity of ascending time slot/subframe is reduced.
By above step, the cell that the embodiment of the present invention realizes from centralized management equipment root into self-interference cluster issues Time slot ratio adjustment order, dynamic adjusts the uplink and downlink timeslot ratio of all cells in self-interference cluster, it is achieved thereby that in the time-division Uplink and downlink timeslot is dynamically adjusted in duplex communication system, to adapt to the dynamic change of uplink and downlink business, optimizes resource utilization.
It refer to Fig. 2, the uplink and downlink timeslot method of adjustment of another tdd communication systems provided in an embodiment of the present invention, When applied to the centralized management equipment, comprise the following steps
Step 21, what the base station that centralized management equipment is received in self-interference cluster was sent is used to ask to adjust the one of the base station The time slot ratio adjust request of the uplink and downlink timeslot ratio of cell, the cell are the cell in the self-interference cluster.
Here, as a kind of realization method, the time slot ratio adjust request can be the described of the expression base station The current uplink and downlink timeslot ratio of cell does not meet the asymmetric event message of practical business demand.For example, the base station is being sentenced The current uplink and downlink timeslot ratio for the cell of breaking is not when meeting practical business demand, to centralized management equipment send described in it is not right Claim event message, to ask adjustment time slot ratio.
Above-mentioned time slot ratio adjust request usually carries the identification information of the base station and the cell, in order to Centralized management equipment identifies the source of the request.As a kind of realization method, above-mentioned time slot ratio adjust request can also carry There is the first indication information of the expectation adjustment direction of the uplink and downlink timeslot ratio of the cell, for example, it is desirable to which adjustment direction is to increase Add ascending resource and reduce downlink resource or increase downlink resource and reduce ascending resource etc. or even institute can also be provided The desired uplink and downlink timeslot configuration of cell is stated, such as in 7 kinds of ascending-descending subframes configuration of existing TD-LTE system protocol definition Any one.
Step 22, the time slot ratio adjust request that the centralized management equipment is sent according to each base station received, Judge whether the self-interference cluster meets default time slot ratio regularization condition.
Here, when the default time slot ratio regularization condition can be that request carries out the adjustment of some direction in self-interference cluster The number of cells or cell ratio of gap ratio exceed corresponding thresholding, at this point it is possible to the time slot ratio sent according to each base station Adjust request, the number of cells of expectation adjustment direction of the statistics with identical uplink and downlink timeslot ratio, according to the cell number Whether the ratio of amount or the number of cells in the multiple cell judges whether the self-interference cluster full beyond corresponding thresholding The default time slot ratio regularization condition of foot.
Here, the time slot ratio adjust request can also carry to represent having for the time slot ratio adjust request The second indication information of time is imitated, at this point, the further current time of the centralized management equipment and the adjustment of each time slot ratio please The effective time asked determines currently valid time slot ratio adjust request, and then counts described with identical uplink and downlink timeslot The number of cells of the expectation adjustment direction of ratio.
Step 23, when meeting the time slot ratio regularization condition, the centralized management equipment determines uplink and downlink timeslot tune Whole target configuration information, the corresponding base station of each cell into the self-interference cluster send one and carry uplink and downlink timeslot tune The time slot ratio adjustment order of whole target configuration information.
Here, exceed in number of cells/ratio of the expectation adjustment direction with identical uplink and downlink timeslot ratio It, can be according to the expectation adjustment direction of these cells, to be adjusted to current time slot ratio, for example, working as during corresponding thresholding It is that when increasing ascending resource and reducing downlink resource, can suitably increase the quantity of ascending time slot/subframe, subtract it is expected adjustment direction The quantity of few descending time slot/subframe；In another example when it is to increase downlink resource and reduce ascending resource it is expected adjustment direction, it can Suitably to increase the quantity of descending time slot/subframe, the quantity of ascending time slot/subframe is reduced.
By above step, the embodiment of the present invention realizes the self-interference sent by centralized management equipment according to each base station The time slot ratio adjust request of cell in cluster, the cell into self-interference cluster issue time slot ratio adjustment order, and dynamic adjustment is certainly The uplink and downlink timeslot ratio of all cells in cluster is disturbed, it is achieved thereby that dynamically adjusting uplink and downlink in tdd communication systems Time slot to adapt to the dynamic change of uplink and downlink business, optimizes resource utilization.
In addition, in order to ensure all cells in self-interference cluster can the configuration of synchronous adjustment uplink and downlink timeslot, above-mentioned After step 23, each cell that the centralized management equipment may also wait for receiving in the self-interference cluster passes through own base station The confirmation message for time slot ratio adjustment order sent.If in a default time-out time, institute is not received yet The above-mentioned confirmation message that all cells in self-interference cluster are sent is stated, then the corresponding base of each cell into the self-interference cluster Stand send one for cancel adjustment respective cell uplink and downlink timeslot ratio mandatum cassatorium, so as to cancel each cell up and down The adjustment operation of row time slot ratio.
It continues with reference to figure 3, the uplink and downlink timeslot adjustment side of tdd communication systems provided in an embodiment of the present invention Method when applied to base station, comprises the following steps：
Step 31, base station receives the one of centralized management equipment transmission for adjusting the upper and lower of the first community of the base station The time slot ratio adjustment order of row time slot ratio, the first community is the cell in self-interference cluster.
Step 32, the base station adjusts the target configuration for the uplink and downlink timeslot adjustment that order carries according to the time slot ratio Information adjusts the uplink and downlink timeslot ratio of the first community；
Wherein, the self-interference cluster includes multiple cells, any cell in the multiple cell with it is the multiple small At least one cell in area is there are co-channel interference, and any cell is not present with the cell outside the self-interference cluster and is done with frequency It disturbs.
By above step, the time slot ratio that base station can be sent according to centralized management equipment adjusts order, and dynamic adjusts Uplink and downlink timeslot.
It continues with reference to figure 4, the uplink and downlink timeslot tune of another tdd communication systems provided in an embodiment of the present invention Adjusting method when applied to base station, comprises the following steps：
Step 41, base station sends one for asking to adjust the uplink and downlink of the first community of the base station to centralized management equipment The time slot ratio adjust request of time slot ratio, the first community are the cell in self-interference cluster；
Here, the time slot ratio adjust request can carry the expectation of the uplink and downlink timeslot ratio of the first community First indication information of adjustment direction, to represent desired adjustment direction to centralized management equipment.
Step 42, the base station is used to adjust the first community in receive the centralized management equipment transmission one After the time slot ratio adjustment order of uplink and downlink timeslot ratio, the uplink and downlink timeslot tune of order carrying is adjusted according to the time slot ratio Whole target configuration information adjusts the uplink and downlink timeslot ratio of the first community.
In above step, base station asks to carry out the time slot ratio tune of the first community in self-interference cluster to centralized management equipment Adjustment order whole, and that centralized management equipment is waited to issue carries out the adjustment of uplink and downlink timeslot based on the adjustment order.
Before above-mentioned steps 41, base station can also judge the current uplink and downlink timeslot ratio of the first community of this base station Whether example meets practical business demand, and when being unsatisfactory for practical business demand, into above-mentioned steps 41.Here, the time slot Ratio adjust request can be that the current uplink and downlink timeslot ratio for the first community for representing the base station does not meet actual industry The asymmetric event message of business demand.
It, can basis when whether the current uplink and downlink timeslot ratio for judging the first community meets practical business demand The resource requirement of the uplink and downlink business of the first community is with current uplink and downlink timeslot ratio or according to the first community The resource utilization ((such as uplink and downlink Physical Resource Block PRB utilization rates etc.)) of uplink and downlink business, judges that described first is small Whether the current uplink and downlink timeslot ratio in area meets practical business demand, and then determine the uplink and downlink timeslot ratio of first community It is expected adjustment direction.
For example, the resource requirement ratio in the uplink and downlink business of first community reaches beyond current uplink and downlink timeslot ratio One pre-determined threshold (i.e. the former subtract the latter difference be greater than or equal to first pre-determined threshold, the first pre-determined threshold be one Positive number), then illustrate that the demand of current ascending resource is more, the demand of downlink resource is less, and in current uplink and downlink timeslot ratio Ascending resource it is less, downlink resource is more, judges that the current uplink and downlink timeslot ratio of first community is unsatisfactory for reality at this time Business demand, and the expectation adjustment direction of the uplink and downlink timeslot ratio of first community is to increase ascending resource and reduce downlink to provide Source.Reach the second pre-determined threshold less than current uplink and downlink timeslot ratio in the resource requirement ratio of the uplink and downlink business of first community (i.e. the latter subtracts the former difference more than or equal to second pre-determined threshold, and the second pre-determined threshold is a positive number), then say The demand of bright current ascending resource is less, and the demand of downlink resource is more, and the ascending resource in current uplink and downlink timeslot ratio More, downlink resource is less, also judges that the current uplink and downlink timeslot ratio of first community is unsatisfactory for practical business demand at this time, And the expectation adjustment direction of the uplink and downlink timeslot ratio of first community is to reduce ascending resource and increase downlink resource.
In another example first community uplink (or downlink business) resource requirement uplink and downlink business resource aggregate demand In ratio, the difference with current uplink and downlink timeslot ratio, if more than or equal to the 3rd pre-determined threshold, to judge first community Current uplink and downlink timeslot ratio whether be unsatisfactory for practical business demand, and then according to uplink and downlink business demand and when front upper and lower Row time slot, to determine above-mentioned expectation adjustment direction.
For another example according to the resource utilization of the uplink and downlink business of the first community, for example, when the resource of uplink service Utilization rate be more than the 4th pre-determined threshold, and the resource utilization of downlink business be less than five pre-determined thresholds when, judge first community Current uplink and downlink timeslot ratio be unsatisfactory for practical business demand, and the expectation adjustment side of the uplink and downlink timeslot ratio of first community To being to increase ascending resource and reduce downlink resource, etc..
The embodiment of the present invention can be pre-configured strategy and corresponding thresholding according to various, come judge first community it is current on Whether descending time slot ratio meets practical business demand, and then when being unsatisfactory for, the above-mentioned phase is determined according to practical business demand It hopes adjustment direction, no longer repeats one by one herein.
It is understood that avoid whether the current uplink and downlink timeslot ratio of first community meets practical business demand The frequent change of judging result, base station can configure a wave filter or hysteresis for judging thresholding, for example, for above-mentioned the The resource requirement ratio of the uplink and downlink business of one cell beyond current uplink and downlink timeslot ratio reach the first pre-determined threshold when, judge The current uplink and downlink timeslot ratio of first community is unsatisfactory for the scene of practical business demand, can set the 6th pre-determined threshold, when The resource requirement ratio of the uplink and downlink business of first community and the difference of current uplink and downlink timeslot ratio from the first pre-determined threshold by When being gradually down to six pre-determined thresholds, just judge that the current uplink and downlink timeslot ratio of first community meets practical business demand, without It is once the resource requirement ratio of the uplink and downlink business of first community is less than first in advance with the difference of current uplink and downlink timeslot ratio Gating judges that the current uplink and downlink timeslot ratio of first community meets practical business demand in limited time, here, the 6th pre-determined threshold To be less than a positive number of the 5th pre-determined threshold.
