Technical field

The embodiment of the present invention relates to wireless communication technology field, particularly relates to wireless communications method, base station and terminal (UserEquipment, UE).

Background technology

In LTE system, consider the reason such as test complexity, physical layer channel design, the bandwidth of community is not that arbitrary value can configure, and must be configured to one of 6 kinds of cellular standards bandwidth of LTE protocol regulation.But the bandwidth that some operator possible applies for not is one of above-mentioned 6 kinds of standard bandwidths, that such as apply for is 12M, then can only use at most and be less than and immediate standard bandwidth 10M, and other 2M bandwidth causes the waste of frequency spectrum resource because not using.

In addition, in order to the performance requirement of satisfied communication system of new generation, by disposing lower powered base station or transmitting/receiving node in macro base station (MacroeNodeB) coverage in systems in which, as micro-base station (microeNodeB), scytoblastema station (picoeNodeB), Home eNodeB (HomeeNodeB), relay station (RelayeNodeB), the access points (accesspoint) such as remote radio front end (RRH), the hot spot region that can strengthen in macro base station coverage covers, indoor blind spot covers, the cell edge covering that macro base station is administrative, and promote community average throughput, cell edge throughput, the uplink/downlink availability of frequency spectrum etc. of community.The transmit power level of each network node may be different, may overlap be there is in the coverage of each node, in order to improve the spectrum utilization efficiency of system, low power base station and macro base station can be made further to carry out spectrum reuse wholly or in part, or use close frequency spectrum.Like this, between each node just may there is interference in signal transmission.Control channel, mainly Physical Downlink Control Channel (PDCCH) carrying over the whole width, and interference can affect the performance of control channel or data channel Channel Detection and the reliability of transmission.Control channel is more important compared to data channel, and therefore the interference of control channel is more urgently to be resolved hurrily.

In order to solve above mentioned problem, the spectrum efficiency of further raising system and user throughput, reduce interference effect, and carrier wave section (CarrierSegment) is suggested in enhancing LTE (LTE-A) system as a kind of technology.Carrier wave section is the frequency band expanded on standard bandwidth basis, and as shown in Figure 1, the subdistrict frequency band that bandwidth is B comprises the frequency band (bandwidth is standard bandwidth B0) of the standard bandwidth shown in dash area and the extending bandwidth of standard bandwidth frequency band both sides.The extending bandwidth section of comprising 1 (Segment1) and section 2 (Segment2) in Fig. 1, section 1 and section 2 are the aforementioned carrier wave section mentioned.

For support LTERel8/9 agreement, and do not support the UE of LTERel-10 agreement, be Rel8/9UE hereinafter referred to as this UE, standard bandwidth frequency band can only be used, and carried out accessing and transfer of data by the Rel8/9 cell carrier of this standard bandwidth frequency band as a standard, PDCCH is carried on the wide band each several part of this index zone.Carrier wave section, comprises Segment1 and Segment2, does not carry PDCCH, can not be used by Rel8/9UE.

As can be seen from the above description, carrier wave section is the extending bandwidth of a backward compatibility, and carrier wave section still belongs to the frequency range of this community, can not be independent.The introducing of carrier wave section, the support of community to nonstandard bandwidth is made to become possibility, namely in whole non-standard frequency band, mark off the community of frequency band as Rel8/9 compatibility of a standard bandwidth, the part of both sides is as expansion, do not support the UE of carrier wave section like this, such as Rel8/9UE, the resource on compatible community can be used, and support that the UE of carrier wave section is except can using the resource on compatible community, the carrier wave section resource that both sides can also be used to expand, thus the frequency spectrum resource of operator can be utilized more fully, and because the resource of additional extension part does not carry PDCCH, therefore the expense of control signal is also reduced, thus lifting spectrum efficiency.

In current LTE standard, only propose the concept of carrier wave section, discuss the feature of carrier wave section.But how to realize this feature in a network also not relate to.
