Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Should understand, technical scheme of the present invention can be applied to various communication systems, for example: global system for mobile telecommunications (GSM, Global System of Mobile communication) system, code division multiple access (CDMA, Code Division Multiple Access) system, Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple Access) system, GPRS (GPRS, General PacketRadio Service), Long Term Evolution (LTE, Long Term Evolution) system, advanced Long Term Evolution (LTE-A, Advanced long term evolution) system, universal mobile telecommunications system (UMTS, Universal Mobile Telecommunication System) etc.
Will also be understood that, in embodiments of the present invention, the base station can be the base station (BTS among the GSM, Base Transceiver Station), also can be base station (NB, NodeB) among the WCDMA, can also be evolved base station (eNB or the eNodeB among the LTE, or access point (AP, Access Point) Evolutional Node B).The LTE heterogeneous network that the embodiment of the invention will be disposed take macro base station and small base station describes as example, but the embodiment of the invention is not limited to this, and for example, when small base station was RRH (Remote Radio Head), the embodiment of the invention was applicable equally.In addition, the embodiment of the invention also can be used for homogeneous network.
In the LTE system, the base station (for example, eNodeB) can send PDSCH at carrier wave, and need to send the PDCCH corresponding with this PDSCH.The information such as resource allocation information, modulation coding mode and transmission block size that comprise PDSCH corresponding to scheduling among this PDCCH.PDCCH has two kinds of scheduling modes, and a kind of is the PDSCH that a PDCCH on the carrier wave can dispatch this carrier wave, and another kind is that a PDCCH on the carrier wave can dispatch the PDSCH on other carrier waves, namely strides carrier dispatching.
According to the embodiment of the invention, when striding carrier dispatching, introduce the concept of scheduling carrier wave and the carrier wave that is scheduled.The PDCCH of scheduling carrier wave can dispatch the PDSCH of this scheduling carrier wave self, also can dispatch the PDSCH of the carrier wave that is scheduled, the PDCCH of carrier wave of being scheduled can be empty (not transmitted power), the transmitted power of PDCCH of carrier wave of perhaps being scheduled can be lower, disturbs thereby can not produce peripheral base station.Especially, under the isomery deployment scenario, if macro base station has used a carrier wave as the above-mentioned carrier wave that is scheduled, and the small base station in the macro base station coverage selects this carrier wave as the carrier wave of oneself, even the scheduling carrier wave of conduct oneself, because macro base station uses this carrier wave as being scheduled carrier wave, and the zone of the PDCCH on the carrier wave that is scheduled transmitting power is 0 or lower, so the interference to the PDCCH zone of small base station on this carrier wave is low, guaranteed the quality of wireless channel of small base station on this carrier wave, reduced co-channel interference, particularly the co-channel interference in RE zone.For same base station, the PDCCH of its carrier wave that is scheduled also can dispatch it with the PDCCH of scheduling carrier wave, and the PDCCH Resource Supply that namely is scheduled uses to PDSCH.Because the transmitting power of PDSCH is less, therefore also low to disturbing on every side, like this, when guaranteeing to reduce interference, resource corresponding to PDCCH zone of vacating obtained effective utilization.
The present invention mainly solves the problem of co-channel interference in the LTE network design scene, and from the angle of frequency domain based on carrier aggregation technology, introduce scheduling carrier wave and the carrier wave that is scheduled, solve interference problem.According to the embodiment of the invention, for fear of co-channel interference, can coordinate the carrier wave configuration between the base station, so that the scheduling carrier wave that is disturbed the base station can be different from the scheduling carrier wave of interference base station, perhaps be disturbed the scheduling carrier wave of base station corresponding to the carrier wave that is scheduled (namely the carrier wave that is scheduled with interference base station is identical) of interference base station.Alternatively, if there is the base station of using single carrier wave, also can coordinate to use the scheduling carrier wave of the base station of a plurality of carrier waves to be different from the carrier wave of the base station of using single carrier wave, perhaps coordinate to use the carrier wave of carrier wave corresponding to the base station of using single carrier wave that be scheduled of the base station of a plurality of carrier waves.This needs to carry out between the base station the mutual of carrier information, the particularly information interaction of the scheduling characteristic of carrier wave.According to the embodiment of the invention, the scheduling characteristic of carrier wave is used to indicate the base station and uses this carrier wave as the scheduling carrier wave carrier wave that still is scheduled.The base station of mentioning according to the embodiment of the invention with a carrier set that is scheduled that carrier wave is corresponding, referring to can be by the set of the carrier wave of this carrier dispatching in this base station.Similarly, the base station of mentioning according to the embodiment of the invention with a scheduling carrier wave set that carrier wave is corresponding, refer in this base station the set of the carrier wave that can dispatch this carrier wave.All kinds of carrier waves " difference " or " identical " of describing among all embodiment of the present invention can be center frequency point " difference " or " identical " of carrier wave, perhaps can be frequency band " difference " or " identical " of carrier occupancy.All kinds of carrier set of describing among all embodiment of the present invention, all the band information that takies of available carrier wave identifies carrier wave.
According to existing LTE technology, the residential quarter of base station is all corresponding with a carrier wave, therefore, scheduling carrier wave or the carrier wave that is scheduled that all embodiment of the present invention describe also can be corresponding with the residential quarter of base station, namely in actual applications, the information of the scheduling characteristic of the carrier wave that transmits between the different nodes that the present invention mentions (for example, the information of another base station configuration carrier wave of the information of a base station configuration carrier wave and request) also can represent with the scheduling characteristic of residential quarter.The scheduling carrier wave information of be scheduled carrier wave or the carrier wave that is scheduled of the scheduling carrier wave that transmits between the different nodes that the embodiment of the invention is mentioned (for example, the information of another base station configuration carrier wave of the information of a base station configuration carrier wave and request), can represent that with the scheduling carrier wave of be scheduled carrier wave or the residential quarter of residential quarter perhaps the dispatching cell be scheduled residential quarter or the residential quarter of residential quarter represents.
In practical communication system, main carrier and scheduling carrier wave are the concepts that can be equal to fully, and the carrier wave that is scheduled herein also can expand to the concept of auxiliary carrier wave.Therefore, all embodiment of the present invention are based on the description of scheduling carrier wave, the carrier wave that is scheduled, and also can correspondence expand to the description of main carrier (or Pcell), auxiliary carrier wave (or Scell).

For example, in downlink transfer, PDCCH and PDSCH time division multiplexing are in a subframe.In subframe, PCFICH (Physical Control Format Indicator Channel, Physical Control Format Indicator Channel) indication PDCCH shared OFDM (Orthogonal Frequency Division Multiplexing in subframe, OFDM) symbol numbers can be called the number that PDCCH takies the OFDM symbol here.If the second base station need to use the carrier wave of the first base station as the carrier wave that is scheduled of oneself, then the number of the OFDM symbol that the PDCCH of the first base station on this carrier wave takies need to be known in the second base station, in order to correctly dispose the physical channel of the carrier wave at place, the second base station, comprise the number of the OFDM symbol that takies that disposes PDCCH and the number of the OFDM symbol that PDSCH takies.For example, the first base station has used this carrier wave as scheduling carrier wave, and used 3 OFDM symbols to be PDCCH, the residue symbol is PDSCH, the second base station obtains this information, select this carrier wave to be the carrier wave that is scheduled, only keep corresponding OFDM symbol on this carrier wave that is scheduled and be PDSCH, the OFDM position corresponding with the PDCCH of the first base station be transmitted signal not.The number of its OFDM symbol of taking at the PDCCH of this carrier wave that the second base station can be notified by X2 interface/OAM in the first base station.PCFICH also can be sky, and at this moment, the number of the OFDM symbol that PDCCH takies can obtain by both sides' agreement.Alternatively, because the summation of the OFDM symbol numbers in subframe equals the OFDM symbol numbers sum that OFDM symbol numbers and PDSCH take that takies of PDCCH, so the number of the OFDM symbol that also can take according to the PDSCH in the subframe is determined the number of the OFDM symbol that PDCCH takies.At this moment, what transmit between the first base station and the second base station is the Radio Resource that PDSCH takies, the number of the OFDM symbol that takies such as PDSCH.In addition, the Radio Resource that the second base station takies based on the PDCCH of the above-mentioned carrier wave that is scheduled, can determine the to be scheduled PDCCH Radio Resource of vacating of carrier wave, the Radio Resource of the PDCCH that these are vacated can be used as PDSCH and uses, and utilizes the PDCCH of its corresponding scheduling carrier wave that it is dispatched.Because the transmitting power of PDSCH is less, therefore also low to disturbing on every side, like this, when guaranteeing to reduce interference, resource corresponding to PDCCH zone of vacating obtained effective utilization.
According to embodiments of the invention, above-mentioned the first base station is macro base station, and above-mentioned the second base station is small base station, and perhaps above-mentioned the first base station is that small base station and above-mentioned the second base station are macro base station.For example, the scheduling carrier wave that can make a base station not use another base station to use perhaps not with the scheduling carrier wave of this scheduling carrier wave as this base station, thereby avoids two scheduling carrier waves between the base station to bump.
