Abstract
The invention discloses a method for activating the ABS configuration of a small base station, an ABS configuration method and a base station. The method for activating the ABS configuration of the small base station includes the following steps that: a macro base station receives reference signal receiving power (RSRP) information which is reported by UE (user equipment) in the coverage range of the macro base station, wherein the RSRP information contains reference signal receiving power (RSRP Serving) of the macro base station and reference signal receiving power (RSRP Neighbour) of the small base station, wherein the small base station is in the coverage range of the macro base station; the macro base station receives an small base station ABS configuration activating request transmitted by the small base station, wherein the small base station ABS configuration activating request is transmitted when the small base station evaluates that the load of the small base station is smaller than a second preset threshold value; and the macro base station activates the ABS configuration of the small base station according to the small base station ABS configuration activating request and the load situation of macro base station users in a small base station CRE coverage range.
Description
Technical field
The present invention relates to communication technical field, be specifically related to activate method that little base station ABS configures, ABS collocation method and base station.
Background technology
Mobile communication standard organizes 3GPP to propose heterogeneous network in the standardization of LTE-Advanced, the i.e. network of macro base station Macrocell and little base station mixed networking, its medium and small base station comprises far-end radio node, low power nodes (as femto base station Picocell, Home eNodeB, relaying etc.).
Macro base station the make user equipment (UE) number that be connected to little base station different from little base-station transmitting-power is far smaller than the UE number being connected to macro base station, cause macro base station and little load of base station unbalance.Therefore, 3GPP proposes coverage extension technology CRE (CellRangeExpansion), after CRE is opened in little base station, the UE of macro base station is preferentially switched to little base station, reach the effect of load balancing, such as the Reference Signal Received Power RSRP (ReferenceSignalReceivingPower) of little base station is added that certain deviant is to increase its descending coverage, thus make the UE near the macro base station edge of little base station select to be linked into little base station.
UE in the CRE coverage of little base station can be subject to the strong descending interference of adjacent macro base station.In order to effectively solve interference problem, 3GPP proposes interference coordination technique eICIC between enhancement type district (enhancedInter-CellInterferenceCoordination).To be macro base station reduce transfer of data to protect the transfer of data of little base station to time domain eICIC in almost blank subframe ABS (AlmostBlankSubframe), ABS requires that macro base station only sends cell special reference CRS (Cell-specificreferencesignals) and necessary signal, as Physical Broadcast Channel PBCH signal, master sync signal PSS (PrimarySynchronousSignal), auxiliary synchronous signals SSS (SecondarySynchronizationSignal), not transmitting physical DSCH Downlink Shared Channel PDSCH signal (PhysicalDownlinkSharedChannel).
Therefore, effective ABS collocation method and activate little base station ABS configure method macro base station and little load of base station equilibrium are played a key effect.
The way of prior art is: when macro base station load evaluation value higher than predetermined threshold value and little load of base station assessed value lower than the second predetermined threshold value time, macro base station activates little base station ABS and configures, and ABS configuration to be macro base station formulate based on the loading condition of little base stations all in its coverage and the loading condition of self.
Prior art Problems existing is: existing ABS configuration is owing to considering loading condition and the loading condition of self of the little base station of all activated ABS configuration in macro base station coverage, thus the time that ABS is configured is longer; The method that existing activation little base station ABS configures, owing to considering the overall load situation of little base station and macro base station, have ignored the loading condition of the user equipment (UE) of the macro base station be in the CRE coverage of little base station.Such as, macro base station heavier loads and reach predetermined threshold value, and the load being in the user equipment (UE) of the macro base station in the CRE coverage of little base station is comparatively light, now, the load balancing effect that little base station is opened after CRE is not obvious.
