Description

Communication means and the base station of using this communication means
Technical field
The present invention relates to communication technical field, more specifically, relate to the base station of communication means and application communication method.
Background technology
Many antennas (MIMO:Multiple In Multiple Out) Radio Transmission Technology is used to the space resources in the wireless transmission at transmitting terminal and many antennas of receiving terminal configuration, obtains spatial reuse gain and space diversity gain.Information theory research shows that the capacity of mimo system is along with the minimum value linear growth of number of transmit antennas and reception antenna number.The sketch map of mimo system is as shown in Figure 1, and among Fig. 1, many antennas of transmitting terminal and receiving terminal constitute the multi-antenna wireless channel, comprise spatial information (si).In addition, OFDM (OFDM) technology has stronger anti-fading ability and higher frequency efficiency, is fit to the high speed data transfer in multi-path environment and the fading environment.With the MIMO-OFDM technology that MIMO technology and OFDM technology combine, become the core technology of next-generation mobile communications.
For example, 3GPP (3G (Third Generation) Moblie gpp) tissue is the international organization in the moving communicating field, and she plays an important role in the standardization effort of 3G cellular telecommunication art.The 3GPP tissue designs EUTRA (UMTS of evolution and continental rise radio insert) and EUTRAN (the UMTS net of evolution and continental rise radio access network) since the second half year in 2004, and this project also is called as LTE (Long Term Evolution) project.The down link of LTE system adopts the MIMO-OFDM technology exactly.In April, 2008,3GPP is organized in the China Shenzhen meeting, begins to inquire into the standardization effort (being called as the LTE-A system at present) of 4G cellular communication system.At the meeting, the notion of a kind of " multi-antenna multi-base station cooperation " by name obtains extensive concern and support, and its core concept is that a plurality of base stations of employing are that a user or a plurality of user provide communication service simultaneously, thereby improves the message transmission rate of cell boundary users.
By the end of in March, 2010, about the multi-antenna multi-base station cooperation, the main reference standard file of main conclusions: 3GPP TR 36.814 V9.0.0 (2010-03); " Further advancements forE-UTRA physical layer aspects (Release 9) ", (report of 3GPP organizational technology, numbering: 36.814; Version: V9.0.0; Date: in March, 2010, " future development of the physical layer aspect that the general continental rise radio of evolution inserts "), summarize as follows:
● the subscriber equipment under the multi-antenna multi-base station service need be reported the channel status/statistical information of the link between each cell base station and the subscriber equipment to one group of sub-district.This group sub-district is called the measuring assembly of multi-antenna multi-base station transmission.
● the cell base station of subscriber equipment actual feedback information can be a sub-set of measuring assembly, is called the cooperation set of multi-antenna multi-base station transmission.(measuring assembly that the cooperation set of multi-antenna multi-base station transmission and multi-antenna multi-base station transmit can be identical).
● the cell base station in the cooperation set of multi-antenna multi-base station transmission participates in directly or indirectly in the transmission of the PDSCH (Physical Downlink Shared Channel: Physical Downlink Shared Channel, the i.e. data channel of subscriber equipment) to subscriber equipment and goes.
● many base stations are participated in the cooperation transmission manner directly; Be called JP (Joint Processing; Combined Treatment), requires to share many base stations of giving the participation cooperation to the PDSCH signal of subscriber equipment, can be subdivided into two kinds of methods; A kind of JT of being called (Joint Transmission: unite emission) refers to that many base stations are simultaneously to its PDSCH signal of subscriber equipment emission; Another kind is called DCS (Dynamic Cell Selection: dynamic cell is selected), is engraved in when referring to each in many base stations, only selects the strongest base station of signal link to its PDSCH signal of subscriber equipment emission.
● many base stations are participated in the cooperation transmission manner indirectly, are called CB/CS (CoordinatedBearmforming/Coordinated Scheduling: wave beam coordination/scheduling is coordinated), do not require and share many base stations of giving the participation cooperation to the PDSCH signal of subscriber equipment.In the method, pass through launching beam/resource of the PDSCH of coordination different user devices between many base stations, reach the purpose that suppresses the phase mutual interference;
● for the subscriber equipment that has disposed multi-antenna multi-base station cooperation transmission, feedback information is being fed back to the master separately to each base station, and feedback transmission occurs on the ascending resource of serving BS.
Aspect JP, in order to obtain better system performance, subscriber equipment often need obtain more channel condition information, and this just needs a plurality of base stations to send quality good channel state information-downlink reference signal confession subscriber equipment detection channel status.In order to improve the quality of BTS channel state information-downlink reference signal; A kind of data mechanism (PUSCH muting) of mourning in silence is proposed in the LTE-A system; Promptly for the channel condition information-downlink reference signal that makes other base stations does not receive bigger interference, the transfer of data of base station is mourned in silence in the position of the channel condition information-downlink reference signal of other base stations.Referring to non-patent literature: 3GPP TSG RAN WG1, R1-106522, Huawei; HiSilicon, NTT Docomo, Samsung; LG Electronics; CATT, Panasonic, " Way forward on CSI-RS andmuting configurations exchange over X2 interface ".
Aspect CB/CS; Have a kind of down transmitting power control method based on the frequency spectrum resource piece in the LTE system: the base station is a unit with the frequency spectrum resource piece; Send the transmitting power indication to adjacent base station; This indication is a reporting unit with the frequency spectrum resource piece, for each frequency spectrum resource piece, indicates transmitting power and whether surpasses preset thresholding.Receive the base station of transmitting power indication, can take measures such as scheduling of resource, avoid the user who is subject to disturb is assigned to the frequency spectrum resource piece at strong jamming place.Referring to document: 3GPP TS36.423, " X2 application protocol " (the 3GPP standardization document, numbering: 36.423, " application protocol of X2 interface ").This down transmitting power control method has simple and flexible, the less advantage of signaling consumption.
In addition, 3GPP research report 36.814 (3GPP TR 36.814 V9.0.0, EvolvedUniversal Terrestrial Radio Access (E-UTRA); Further advancements forE-UTRA physical layer aspects has defined some notions and the basic terms in the multi-antenna multi-base station collaboration scenario in 3GPP).
Serving cell (Serving cell) refers to the sub-district of single transmission PDCCH (Physical Downlink Control Channel) information, and this is a notion existing among the LTE.
Subscriber equipment in the multi-antenna multi-base station cooperation need be reported the channel status/statistical information of the link between each cell base station equipment and the subscriber equipment to one group of sub-district.This group sub-district is called multi-antenna multi-base station cooperation measuring assembly (measurement set).The sub-district of subscriber equipment actual feedback information can be a sub-set of measuring assembly, is called to report set (reported cells).Measuring assembly can be identical with multi-antenna multi-base station team work set (cooperating set), and the cell base station equipment in latter's set is participated in the transmission to the Physical Downlink Shared Channel of subscriber equipment directly or indirectly.Cooperation set can be not transparent to subscriber equipment yet.For the subscriber equipment that is configured to the multi-antenna multi-base station modality for co-operation, the form that feedback is fed back separately with every sub-district is main, and feedback transmission is carried out on the ascending resource of Serving cell.
The 50th meeting of 3GPP RAN further revised the cooperation of LTE Rel-11 multi-antenna multi-base station research contents (RP-101425, Revised SID Proposal:Coordinated Multi-pointOperation for LTE, Samsung).For enlarging application range; Also brought into the goal in research of multi-antenna multi-base station cooperation such as distributed RRU unconventional deployment scenario such as (Remote Radio Unit, wireless remote modules) in heterogeneous network (heterogeneous networks) and/or the sub-district.According to the conclusion of the 63bis time meeting of 3GPP RAN1, the multi-antenna multi-base station joint study will be carried out to following four deployment scenario:
Scene 1: multi-antenna multi-base station cooperation in standing;
Scene 2: multi-antenna multi-base station cooperation between standing;
Scene 3: many sub-districts ID: all the transmission points during macrocell covers have different sub-district ID;
Scene 4: share sub-district ID: all the transmission points during macrocell covers have identical sub-district ID.
A total hypothesis is that the communication between the transmission point is low delay in above-mentioned all scenes; Limitless volumes; This also is to adopt the benefit the most direct that distributed RRU brought; Because the medium that connects this moment between the transmission point generally is an optical fiber, the restriction of transmission delay and bandwidth is just not too strict.In above-mentioned multi-antenna multi-base station collaboration scenario; No matter whether share sub-district ID between the transmission point; In order to obtain effective CSI (channel condition information) feedback of each transmission point, each transmission point needs independently CSI-RS (channel state information reference signals) form (pattern).
In present standardization is discussed; Still there is not concrete grammar to be used for realizing multi-antenna multi-base station collaboration scenario 4; Mourn in silence with data and/or down transmitting power control is relevant, base station equipment background communication (backhaul communication) method, this problem has constituted the main research contents of patent of the present invention.

In Fig. 2, the covering of base station BS 200 also has 5 distributed RRU down, is respectively R 202, and R 204, and R 206, R 208 and R 210.6 transmission point R 200～R 210 that comprise base station BS 200 have identical sub-district ID.5 distributed RRU have different sub-ID.The covering of base station BS 100 also has 3 distributed RRU down, is respectively R 102, R 104 and R 106.4 transmission point R 100～R 106 that comprise base station BS 100 have identical sub-district ID.The covering of base station BS 300 also has 2 distributed RRU down, is respectively R 302 and R 304.3 transmission point R 300～R 304 that comprise base station BS 300 have identical sub-district ID.All RRU all link to each other through optical fiber with relevant base station, in Fig. 2, are illustrated as dotted line.
In Fig. 2, base station BS 100, BS 200 and BS 300 pass through X2 interface BH 400, and BH402 and BH404 are connected with each other, and in Fig. 2, are illustrated as chain-dotted line.In the LTE-A system, three node layer network configurations of base station, wireless network control unit and core net are simplified to the two-layer node structure.Wherein, the function of wireless network control unit is divided into the base station, and the base station is coordinated through the wireline interface of " X2 " by name with the base station and communicated by letter.It is pointed out that in the future communications system, also possibly exist wave point to coordinate and communicate by letter between the base station.Interface BH 400, BH 402 and BH404 just illustrate to have the medium of communicating by letter between the base station, and the concrete form of this communication media can be the wireline communication network that meets various communication standards (like IPv4, IPv6 etc.).
Below, be given in the basic skills that the realization data are mourned in silence in the multi-antenna multi-base station collaboration scenario 4 with reference to Fig. 3.For the sake of simplicity, at first only, the realization of this method is described with the angle of adjacent base station BS 200 and BS 300.Fig. 5 shows the service area of adjacent base station BS 200 and BS 300 formations.
As shown in Figure 3, at step S301, base station BS 300 receives from the data of base station BS 200 information of mourning in silence.The said data information of mourning in silence is the oriented communication information DS 700 that is sent to base station BS 300 from base station BS 200 shown in Figure 5.The said data information of mourning in silence comprises the mourn in silence indication of position of ID and the designation data of base station BS 300 at least.The ID of base station BS 300 is used for functions such as message route.Said indication can be the positional information of the CSI-RS of the RRU (R 208 and/or R 210) closer with the geographical position of base station BS 300, perhaps can also be the positional information of the CSI-RS of RRU (R 208 and/or R 210) closer with the geographical position of base station BS 300 and base station BS 200.The said data information of mourning in silence can be through producing and transmission in the method for describing with reference to figure 4 after a while.
Then, at step S302, base station BS 300 is carried out data and is mourned in silence according to indication.Particularly; Can carry out data in the position of the CSI-RS of the RRU closer with the geographical position of base station BS 300 (R 208 and/or R 210) and mourn in silence, perhaps can also be that the position of the CSI-RS of RRU (R 208 and/or R 210) closer with the geographical position of base station BS 300 and base station BS 200 is carried out data and mourned in silence.
It is to be noted; If the positional information of the CSI-RS of the RRU (R 208 and/or R 210) that the geographical position of said indication indication and base station BS 300 is closer; Among the said oriented communication information DS 700; The sub-ID that can also comprise the RRU closer with the geographical position of base station BS 300 (R 208 and/or R 210) is so that base station BS 300 is made more excellent selection to its data strategy of mourning in silence.Such as, when the data resource operating position of base station BS 300 is comparatively nervous, base station BS 300 its transfer of data of only can selecting to mourn in silence in the position of channel condition information-downlink reference signal of R 208 or R 210.For another example; Base station BS 300 can pass through scheduling of resource; Restriction is from the downlink of the nearer RRU (for example R 302) of R 208 and/or R 210, reaches the effect of its transfer of data of mourning in silence in the position of channel condition information-downlink reference signal of R 208 and/or R 210; But, for R 304, because it is far away from R 208 and/or R 210, base station BS 300 can not make its data mourn in silence, thereby improves near R 304 quality of services for users.
If the positional information of the RRU (R 208 and/or R 210) that the geographical position of said indication indication and base station BS 300 is closer and the CSI-RS of base station BS 200; In the said oriented communication information; The sub-ID that also comprises the ID of base station BS 200 and/or the RRU closer with the geographical position of base station BS 300 (R 208 and/or R 210) is so that base station BS 300 is made more excellent selection to its data strategy of mourning in silence.Such as, when the data resource operating position of base station BS 300 is comparatively nervous, base station BS 300 its transfer of data of only can selecting to mourn in silence in the position of the channel condition information-downlink reference signal of R 208 or R 210 or base station BS 200.For another example; Base station BS 300 can pass through scheduling of resource; Restriction is from the downlink of the nearer RRU (for example R 302) of the RRU (R 208 and/or R 210) closer with the geographical position of base station BS 300 and/or base station BS 200, reaches the effect of its transfer of data of mourning in silence in the position of the channel condition information-downlink reference signal of RRU closer with the geographical position of base station BS 300 (R 208 and/or R 210) and/or base station BS 200; But, for R 304, because it is far away from RRU (R208 and/or R 210) and/or the base station BS 200 closer with the geographical position of base station BS 300, base station BS 300 can not make its data mourn in silence, thereby improves near R 304 quality of services for users.
Below, the method for base station BS 200 sides is described with reference to Fig. 4.At first, at step S401, produce the data information of mourning in silence.As stated, the said data information of mourning in silence comprises the mourn in silence indication of position of ID and the designation data of the strong jamming base station BS 300 of base station BS 200 at least.
Base station BS 200 can be confirmed its strong jamming base station in several ways, and obtains the ID of strong jamming base station.The most simple a kind of mode is based on signal strength signal intensity and with the principle of range attenuation adjacent base station is confirmed as the strong jamming base station, and obtains the ID of adjacent base station.Because base station and RRU are fixtures generally, belong to the capital construction facility.Therefore, can learn the ID of adjacent base station in advance through network planning table between the base station.Particularly, investigate the base station BS 200 among Fig. 5, it is adjacent with base station BS 300.Therefore, the ID that in data are mourned in silence information, comprises base station BS 300.
In addition, base station BS 200 can know in its 5 RRU (R 202～210) that when arranging RRU R 208 and R 210 are closer with the geographical position of base station BS 300, may receive the larger interference from base station BS 300.Therefore, be necessary to ask channel condition information-downlink reference signal of 300 couples of R of base station BS 208 and R 210 to protect, promptly make base station BS 300 in channel condition information-downlink reference signal position of R 208 and R 210, its transfer of data of mourning in silence.Thereby, the mourn in silence positional information of the CSI-RS that comprises R 208 and R 210 in the information of data.Certainly, data are mourned in silence and also can be comprised the positional information with the CSI-RS of the closer base station BS in the geographical position of base station BS 300 200 self in the information.
In addition, the sub-ID of R 208 and R 210 is known to base station BS 200, thereby as described with reference to Fig. 3, data are mourned in silence can also comprise the sub-ID of the RRU closer with the geographical position of base station BS 300 (R 208 and/or R 210) in the information.Certainly, data are mourned in silence and can be comprised the ID of base station BS 200 self in the information.
Then, at step S402, base station BS 200 is sent in the data that produce among the step S401 mourn in silence information, i.e. oriented communication information DS 700 shown in Fig. 5 through background communication link BH 402 to base station BS 300.
