Embodiment
Embodiments provide a kind of method and apparatus adjusting terminal uplink transmitting power, for suppressing uplink interference, and solving the problem that transmitting power and uplink interference level rise mutually, promoting network performance.
See Fig. 2, a kind of method adjusting terminal uplink transmitting power that the embodiment of the present invention provides comprises:
S201: the first kind interference relevant parameter and the Equations of The Second Kind interference relevant parameter that receive the transmission of each community.
First kind interference relevant parameter at least comprises IoT, also may comprise service quality (Quality of Service, QoS); Equations of The Second Kind interference relevant parameter comprises: strong descending interference Neighboring Cell List, and edge termination number and/or edge termination occupied bandwidth.
Wherein, IoT is measured by base station equipment to obtain; The preparation method of strong descending interference Neighboring Cell List is: cell base station is terminal configuration A3 event, terminal is measured and A3 reporting events by downstream signal, qualified adjacent area is reported to base station, such as, the adjacent area of downstream signal intensity level difference within 6 decibels (dB) is reported to.The reporting information of base station statistics terminal, selects n the strong descending interference Neighboring Cell List DL of community composition reporting number maximum
i, i is the numbering of this community, and n can be set to 1,2 or other integers.
S202: according to the first kind interference relevant parameter of each community, determine the problem cells being subject to uplink interference.
Step S202 specifically comprises: according to the IoT of each community, determines region-wide average IoT; According to the community that IoT exceeds predetermined threshold value than described region-wide average IoT, determine the problem cells being subject to uplink interference.
Particularly, determine that the method for region-wide average IoT is as follows: the uplink interference level that moment t cell i reports is designated as IoT
it (), then region-wide average IoT namely
Wherein, α is filter coefficient and 0≤α≤1, and N is community sum.Determining IoT
avgafter (t), IoT will be met
i(t) >IoT
avgt the community of ()+offset is defined as the problem cells being subject to uplink interference, wherein, offset is predetermined threshold value.
Further, when the first kind interference relevant parameter receiving the transmission of each community comprises QoS, exceed the community of predetermined threshold value than described region-wide average IoT according to IoT, determine the problem cells being subject to uplink interference, comprise: judge whether the QoS that IoT exceeds the community of predetermined threshold value than described region-wide average IoT can meet preset need, and if so, Bu Jianggai community is defined as the problem cells being subject to uplink interference, otherwise, this community is defined as the problem cells being subject to uplink interference.
S203: according to the Equations of The Second Kind interference relevant parameter of each community, determine that the interference described problem cells being produced to uplink interference produces community.
Step S203 specifically comprises: according to the strong descending interference Neighboring Cell List of each community, determine the community being subject to the descending interference in described problem cells; To the community of the descending interference in described problem cells be subject to, be defined as the community described problem cells being produced to uplink interference, and join the uplink interference Neighboring Cell List of described problem cells; According to the uplink interference Neighboring Cell List of described problem cells, determine that the interference described problem cells being produced to uplink interference produces community.
Because the edge termination in a community receives the stronger descending interference in another base station, so this edge termination also can produce stronger uplink interference to another base station.Uplink interference Neighboring Cell List can build in the following manner: for community j, travels through the strong descending interference Neighboring Cell List { DL of each community
i, i=1 ..., N}, finds the community of the descending interference being subject to community j, these communities is joined the uplink interference Neighboring Cell List UL of j
j.See Fig. 3, it is the schematic diagram being obtained uplink interference Neighboring Cell List by strong descending interference Neighboring Cell List.
Next, according to the uplink interference Neighboring Cell List of described problem cells, determine that the interference described problem cells being produced to uplink interference produces community, comprise: according to edge termination number and/or the edge termination occupied bandwidth of each community, determine region-wide average edge number of terminals and/or region-wide average edge terminal occupied bandwidth; Edge termination number in the uplink interference Neighboring Cell List of described problem cells is greater than the community that described region-wide average edge number of terminals and/or edge termination occupied bandwidth are greater than described region-wide average edge terminal occupied bandwidth, produces community as the interference described problem cells being produced to uplink interference.That is, both edge termination number and region-wide average edge number of terminals can have been compared, also edge termination occupied bandwidth and region-wide average edge terminal occupied bandwidth can be compared, edge termination number and region-wide average edge number of terminals can also be compared simultaneously, and edge termination occupied bandwidth and region-wide average edge terminal occupied bandwidth, to determine that the interference described problem cells being produced to uplink interference produces community.Region-wide average edge number of terminals is identical with the computational methods of region-wide average IoT with the computational methods of region-wide average edge terminal occupied bandwidth: be X by the edge termination number scale that moment t cell i reports
it (), region-wide average edge number of terminals is designated as X
avg(t), or the edge termination occupied bandwidth that moment t cell i reports is designated as X
it (), region-wide average edge terminal occupied bandwidth is designated as X
avg(t), then
Wherein, α is filter coefficient and 0≤α≤1, and N is community sum.Because the uplink interference degree of the community in uplink interference Neighboring Cell List to problem cells is different, thus this step has carried out further screening to uplink interference Neighboring Cell List, and the determined interference of this step produces the main interference source that community is actually problem cells.
S204: for each problem cells, notifies that the interference this problem cells being produced to uplink interference produces community reduction terminal uplink transmitting power; And/or, when determining that this problem cells is not interference generation community other problem community being produced to interference, notify that terminal uplink transmitting power is improved in this problem cells.
Described notice produces community reduction terminal uplink transmitting power to the interference that this problem cells produces uplink interference, comprising: notify that the interference to this problem cells generation uplink interference produces the dynamic power control desired value of the edge termination that community reduces and this problem cells is closed on; And/or, notify that the interference this problem cells being produced to uplink interference produces the value that community reduces parameter alpha.
Wherein, notify the dynamic power control desired value of the edge termination that interference generation community reduces and this problem cells is closed on this problem cells being produced to uplink interference, specific implementation is as follows: the decline degree X decibel (dB) carrying SINR_target in the notification, and the cell ID of problem cells; Be convenient to the corresponding terminal of interference generation cell notification and carry out SINR_target adjustment, reduce uplink transmission power.And notice produces to the interference that this problem cells produces uplink interference the value that community reduces parameter alpha, the uplink transmission power disturbing all edge terminations producing community can be made to reduce.
Describedly notify that terminal uplink transmitting power is improved in this problem cells, specifically comprise: notify that the value of parameter P0 is improved in this problem cells.
Particularly, the degree of value that P0 is improved in notice problem cells is that the lifting of the value of YdB, parameter P0 makes the uplink transmission power of all terminals of problem cells raise, disturbs in order to resist adjacent area.Because not indication problem community promotes the value of parameter alpha, the value of parameter alpha still maintains a lower level, and the rising of the uplink transmission power of the edge termination of problem cells is relatively less, avoids the interference strengthened other adjacent area.
It should be noted that and can determine arbitrary problem cells whether simultaneously for the interference of other community produces community according to step S203.In step S204, only when determining that this problem cells is not interference generation community other problem community being produced to interference, just notify that terminal uplink transmitting power is improved in this problem cells, like this, the appearance of the problem that uplink transmission power and uplink interference level can be avoided to rise.
Alternatively, after step S204, when determining that the uplink interference level of arbitrary problem cells returns to normal level, such as, when IoT returns to region-wide average IoT, notify that this problem cells and its interference origin cause of formation community are by the value before the uplink power control Parameter reconstruction such as P0, alpha, SINR_target to amendment.
