Description

Cell dormancy, dormancy information issue and processing method and equipment
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of cell dormancy, dormancy information issues and processing method and equipment.
Background technology
Along with the deployment of Home eNodeB, Microcell etc., traditional homogeneous network of only having macrocell is by the heterogeneous network that is progressively evolved to polytype community and coexists.Under heterogeneous network, macro base station (Marco eNB) can provide basic covering, home base stations (Local eNB) provides among a small circle and covers in macro base station coverage, as shown in Figure 1, wherein Local eNB can be trunking (RN), Home eNodeB (HeNB), micro-base station (Pico) etc.
Existing base station energy-saving mechanism is mainly for the scene that has overlapping covering, such as: by GSM EDGE Radio Access Network (GSM EDGE Radio Access Network, GERAN)/universal terrestrial access network (Universal Terrestrial Radio Access Network, general land wireless network (the Evolved Universal Terrestrial Radio Access Network of UTRAN)/evolution, E-UTRAN) community provides grand covering, E-UTRAN community covers as focus, and focus covers and is positioned at basic coverage.Take substantially cover with focus cover be all E-UTRAN community as example, as shown in Figure 2, wherein macrocell (Marco cell) provides basic covering to the scene of base station energy-saving, other home cell (Local cell) provide focus cover.
Under overlapping covering scene, the Main Function of Hot Spot is exactly the capacity of the basic coverage cell of shunting.Therefore consider in base station energy-saving, Hot Spot only need to just be necessary to open in the time having carrying shunting demand, can close to reach the object of base station energy-saving, i.e. so-called community activation/deactivation mechanism in other situation.Under the state of activation of community, can normally work in community, can normally send various physical layer signals and carry out transfer of data.Under the deactivation status of community, community can not send any signal, can not and user terminal (User Equipment, UE) between carry out data transmit-receive.
The energy-conservation mode by activation/deactivation Hot Spot of Hot Spot realizes.Concrete Hot Spot deexcitation mechanism mainly contains several as follows:
The first, control based on operation and maintenance entity (OAM);
The second, provide base station that focus covers in the time there is no transfer of data demand independently deexcitation whole/part community;
The 3rd, based on macro base station control.
In the time that the base station that provides focus to cover determines its lower certain community of deexcitation, can be switched to other community in the UE of connected state in Jiang Gai community, and in handover request, indicate switch reasons, avoid these communities that UE is switched to this deactivating cell again.In addition, provide base station that focus covers behind its lower certain or some community of deexcitation, by inter-base station interface its lower which community of having notified this focus coverage base station deexcitation of adjacent base station.
After Hot Spot is deactivated, once provide the base station of grand covering to have capacity shunting demand, exceed certain thresholding such as basic coverage cell covers, need so to activate one or more Hot Spot.If it is E-UTRAN community that the community of basic covering is provided, can use so X2Kou community to activate (CellActivation) process; If what basic covering was provided is UTRAN or GERAN community, need so to use Mobility Management Entity indication information transmission (MME Direct InformationTransfer) process of S1 mouth to realize the activation of Hot Spot.
The version 12(Rel-12 of Long Term Evolution (Long Term Evolution, LTE) system) will introduce new carrier type (New Carrier Type, NCT) based on objects such as energy-conservation and reduction interference.NCT compares with traditional community, may introduce some new particular design, such as mode, the exclusive pilot signal in Xin community (Cell-specific reference signals, CRS) pattern (pattern) etc. are found in Xin community.
In order to realize the energy-conservation object of NCT, the possible three kinds of working methods of NCT are as follows:
Mode 1: reduce community CRS expense, be revised as some ms(such as 5ms such as sent CRS by each descending sub frame) CRS of transmission;
Mode 2: dormancy (dormant) state is introduced in community, enter dormant state when not having UE or all UE all not to have data to send Shi Gai community in community;
Mode 3: the combination of mode 1 and mode 2,, in reducing community CRS expense, introduce community dormant state.
Above-mentioned three kinds of NCT working methods as shown in Figure 3.
For heterogeneous network, owing to there being a large amount of Local cell to exist in macro base station coverage, and the general coverage of these Local cell is all smaller, in the time that UE moves in macro base station coverage, UE may constantly carry out the handover operation between Macro cell and Local cell.Cause transfer of data to be interrupted for fear of frequent switching, a kind of mode is exactly to allow the simultaneously resource of polymerization Local eNB and Macro eNB of UE, but RRC connects and maintains under Marco eNB, and Local resource is only for transfer of data, i.e. carrying separates.
Carrying separate mode can allow UE select node transmission nearby, thereby can use lower power and higher MCS to send, and so just can reach the object of economize on electricity, reduction interference, elevator system throughput simultaneously.
To sum up, for heterogeneous network, existing base station energy-saving mechanism only has two kinds of modes to the processing that the local Hot Spot covering is provided: open completely or close completely.Once Hot Spot is closed completely, to no longer send any community and find relevant information, even if UE moves to the coverage of this Hot Spot, macro base station can not find that this Hot Spot can use in time, will be not easy to like this macro base station and judges whether open Hot Spot and more timely UE switched or carry separation.
