Description
Technical field
The present invention relates to long evolving system middle port configuring technical, relate in particular to a kind of method and device that obtains antenna for base station port arrangement parameter.
Background technology
In order to satisfy the demand that growing big bandwidth high-speed mobile inserts, third generation partner program (3GPP, Third Generation Partnership Projects) releases senior Long Term Evolution (LTE-Advanced, Long-Term Evolution advance) standard, LTE-Advanced is for Long Term Evolution (LTE, Long-Term Evolution) evolution of system has kept the core of LTE, adopt a series of technology that frequency domain, spatial domain are expanded on this basis, to reach purposes such as improving the availability of frequency spectrum, increase power system capacity.
Wireless relay (Relay) technology is one of technology among the LTE-Advanced, is intended to the coverage of Extended Cell, reduces the area, dead angle in the communication, balanced load, shift the business of hot zones, saving subscriber equipment (UE, User Equipment) is the transmitting power of terminal.As shown in Figure 1, (RN, Relay-Node), these newly-increased RN and Donor-eNB carry out wireless connections to increase some via nodes between original base station (Donor-eNB) and UE.Wherein, the Radio Link between Donor-eNB and the RN is called back haul link (backhaul link), and the Radio Link between RN and the UE is called access link (accesslink).Downlink data arrives Donor-eNB earlier, passes to RN then, and RN transfers to UE again, otherwise upstream data then.
When access link and back haul link are shared same frequency range, RN need keep being connected on the one hand with Donor-eNB, it is mutual and downlink data is mutual to finish upstream data in the back haul link, need again on the other hand to keep being connected with UE, it is mutual and downlink data is mutual to finish upstream data in the access link, and this will cause the conflict of RN data processing.For addressing this problem, the special back haul link descending sub frame of introducing disposes pseudo-Multicast Broadcast Single Frequency Network (Fake MBSFN, Fake Multicast Broadcast Single FrequencyNetwork), in Fake MBSFN subframe, RN and Donor-eNB carry out data interaction, but the UE in access link does not send signal.
In the LTE system, Donor-eNB adopts the multi-antenna transmitting transferring technology, the single antenna configuration can be arranged as Antenna Port 0, two-antenna configuration such as Antenna Port 0 and Antenna Port 1, four antenna configurations be Antenna Port 0, Antenna Port 1, Antenna Port 2 and Antenna Port 3 or other antenna configurations for example.Adopt different antenna configurations, the different different specific reference signals (Cell-specific reference signals) and different transmission signals in sub-district of antenna port transmission, the UE that is in connection status need measure specific reference signal in sub-district and/or reporting measurement result, also needs to receive the signal of different antennae transmission simultaneously.In the LTE system, Master Information Block (the MIB that UE or RN generally send by the decoding sub-district, Master Information Block) obtains antenna configuration parameters such as antenna port number, MIB itself does not comprise antenna configuration parameters, but MIB need use the scrambling of antenna port configuration parameter, like this, UE or RN can obtain to insert the antenna port configuration parameter of sub-district by blind Detecting from MIB.
After RN inserts the Donor-eNB jurisdiction district and is in normal operating conditions, only receive the signal that Donor-eNB sends at the back haul link descending sub frame, because only in the specific sub-frame scheduling of Donor-eNB, therefore very possible RN can't receive the MIB that Donor-eNB sends to MIB.For example, as shown in Figure 2, subframe # 3 and subframe # 8 are the back haul link descending sub frame, and subframe # 0 is used to dispatch MIB, and RN can only receive the signal that Donor-eNB sends at subframe # 3 and subframe # 8, therefore, RN does not receive the MIB that Donor-eNB sends, thereby can't know the antenna port configuration parameter of Donor-eNB, the variation of the antenna port configuration of Donor-eNB can't be known, thereby the defeated signal of multi-antenna transmitting after the variation can not be effectively received.Because antenna port configuration directly influence the signal transmission manner, the untimely antenna port configuration parameter of knowing Donor-eNB of RN can not keep and being connected of network side, and then can't be that UE under its covering serves.
In addition, in prior protocols, have only when current area switches to Target cell, network side is Radio Resource control (RRC mutual between base station and the UE, Radio Resource Control) signaling just comprises the mobile control information (mobility Control Info) that carries Target cell antenna port configuration parameter, when not switching, network side can not notified the antenna port configuration parameter of UE or its Serving cell that is inserted of RN.When RN can not receive the MIB that Donor-eNB sends, need to solve the problem that RN obtains the antenna port configuration parameter of its Donor-eNB sub-district of inserting.

In the present embodiment, with reference to shown in Figure 4, the identical M that is of the SFN of sub-district Cell_1 and RN jurisdiction district numbering, and the subframe that comprises among this SFN alignment, wherein, M is between 0～1023, comprise 0 and 1023 arbitrary integer.Be provided with in Fake MBSFN sub-frame configuration parameter, subframe #03 and subframe #08 are used for the descending scheduling of Donor-eNB to RN.According to prior protocols, the subframe #00 of sub-district Cell_1 is used to dispatch MIB.
When the antenna port configuration parameter of sub-district Cell_1 will change, RN need obtain the antenna port configuration parameter of the sub-district Cell_1 after the change, so that can continue to receive the downlink data signal that Donor-eNB sends, with reference to shown in Figure 5, idiographic flow is as follows:
Descending scheduling subframe and the MIB scheduling subframe of step 501-502:Donor-eNB by checking RN, judge whether RN can receive the MIB of self, if, then continue step 502, RN is by resolving received MIB, the antenna port configuration parameter of sub-district Cell_1 after acquiring change also continues step 505-506, otherwise, continue step 503;
Here, if the descending scheduling subframe of RN comprises MIB scheduling subframe, then RN can receive MIB, otherwise RN can not receive MIB.
Therefore, in the present embodiment, the result that step 501 is judged is for denying.
Step 503:Donor-eNB sends the dedicated signaling of the antenna port configuration parameter of the sub-district Cell_1 after carrying change to RN;
Here, dedicated signaling can be MAC layer control signaling or rrc layer signaling;
In the practical application, described dedicated signaling can be that (RRCConnection Reconfiguration) or signalings such as RRC connection reconstruction (RRC ConnectionReestablishment) or RRC parameter configuration are reshuffled in the RRC connection in the rrc layer signaling.Particularly, can in as the rrc layer signaling of dedicated signaling, increase the cell that is used to carry the antenna port configuration parameter, as disposing the cell that increases the antenna port configuration parameter in (radioResourceConfigDedicated) information in the dedicated radio resources that RRC connects in reshuffling.

Step 504:RN receives the dedicated signaling that Donor-eNB sent, the antenna port configuration parameter of the sub-district Cell_1 after acquiring change;
Behind the antenna port configuration parameter of sub-district Cell_1 after step 505:RN acquires change, return response message to Donor-eNB;
Concrete, the response message that RN returns to Donor-eNB can be that RRC connects to reshuffle and finishes or the RRC connection reconstruction is finished or the RRC parameter configuration such as finishes at signaling.
Step 506:RN uses the antenna port configuration parameter of the sub-district Cell_1 after changing, carries out data and measures the specific reference signal in sub-district with Donor-eNB by antenna port 0 and antenna port 1.
Particularly, RN adopts existing MIMO technique (MIMO, Multiple Input MultipleOutput) the antenna port configuration parameter of the sub-district Cell_1 after technology use to change, receive the base station by the antenna port that changes configuration send data and the measurement etc. of finishing the specific reference signal in sub-district.
For example, the antenna port number of sub-district Cell_1 after the change is 2, adopts antenna port 0 and antenna port 1, then behind the antenna port configuration parameter of the sub-district Cell_1 of RN after receiving change, the data-signal that reception antenna port 0 and antenna port 1 sends, and the measurement of measuring the specific reference signal in the sub-district of antenna port 0 and antenna port 1.Need to prove that the time-frequency position of the reference signal that the sub-district of different antennae port transmission is specific is stipulated by agreement.
In the practical application, RN is behind the antenna port configuration parameter of the sub-district Cell_1 after the change that receives the Donor-eNB transmission, can use this antenna port configuration parameter immediately, perhaps also can after Donor-eNB returns response message, use this antenna port configuration parameter again at RN.In the present embodiment, step 506 also can be carried out before step 505.In addition, step 505 is an optional step, also can save according to the practical application needs.
