Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of method and apparatus of allocating cell information.
Background technology
At LTE(Long Term Evolution, Long Term Evolution) system and before wireless communication system in, have only a carrier wave in the sub-district.Wherein, the maximum bandwidth of the carrier wave in the LTE system is 20MHz, as shown in Figure 1.At LTE-A(Long Term Evolution-Advanced, the Long Term Evolution enhancing) in the system, the peak rate of system has huge raising than LTE, requirement reaches descending 1Gbps and up 500Mbps, requires if only use a maximum bandwidth can't reach above-mentioned peak rate as the carrier wave of 20MHz.Therefore, the LTE-A system needs the operable bandwidth of terminal extension, introduced CA(Carrier Aggregation thus, carrier aggregation) technology, promptly, with same eNB(base station) under a plurality of continuous or discrete carrier aggregation together, be UE service simultaneously, so that required speed to be provided.The above-mentioned carrier wave that condenses together is called CC(Component Carrier, member carrier again).Each sub-district can corresponding member carrier, and the member carrier of the sub-district correspondence under the different e NB can not polymerization.
For the UE that guarantees LTE can work under the carrier wave of each polymerization, require the maximum bandwidth of each carrier wave to be no more than 20MHz.The distribution of carriers schematic diagram of LTE-A sub-district, as shown in Figure 2.Have under the base station 4 can polymerization carrier wave, the base station can be simultaneously on 4 carrier waves and UE carry out transfer of data, to improve throughput of system.In the LTE-A system, UE can be aggregated in simultaneously and carry out signaling scheduling and professional transmission on a plurality of carrier waves.Angle from resource allocation, three kinds of ascending resource configurations RAN1 can being introduced are tied on certain up-link carrier, this up-link carrier is main carrier (PCC), and the ascending resource of binding comprises channel-quality feedback (CQI), specific schedule request (DSR) and ascending HARQ feedback.In a plurality of carrier waves that UE uses, the carrier wave beyond the main carrier is auxilliary carrier wave (SCC).Main carrier choose be the UE level other, that is, do not require that all UE in the system are certain to use identical main carrier.In addition, the up-downgoing carrier wave that constitutes main carrier need satisfy the corresponding relation that system information SIB2 indicates.
The resident sub-district of UE comprises main plot and auxilliary sub-district, corresponding respectively main carrier and auxilliary carrier wave when pre-polymerization.The LTE-A system all is the sub-district of backward compatibility R8/9 in all sub-districts of R10 version, that is, all there is downlink resource each sub-district, and system information broadcast is all arranged.UE can directly read broadcasting on the main plot, obtain system information.The notice of system information is also consistent with R8/9 with the mode of change, and the mode by dedicated signaling is notified to UE by the base station.UE does not need read system information broadcasting on auxilliary sub-district.
As the resource beyond the main plot, auxilliary sub-district only is configured use at the connected state of UE by the base station.It is that UE adds new auxilliary sub-district that the base station is used RRC connection reconfiguration message usually, and this message comprises information such as the common configuration relevant with assisting the sub-district, specialized configuration and auxilliary cell number.Change the common configuration relevant with auxilliary sub-district if desired, the base station can adopt the mode of this auxilliary sub-district of deletion and then interpolation to realize, but not adopts the mode of revising common configuration.When switching, can be that UE disposes auxilliary sub-district, comprise the information such as common configuration, specialized configuration and auxilliary cell number relevant in the switching command with auxilliary sub-district by switching command in the sub-district, similar when the sub-district is assisted in its configuration mode and initial interpolation.
In R8/9, physical layer standard has defined seven kinds of UL/DL configuration modes, and is as shown in table 1.
Wherein, D represents the DL subframe, and U represents the UL subframe, and S represents the special subframe of TDD system.In the R11 system, a plurality of member carriers that the CA terminal is used can belong to different frequency bands, and the frequency band spacing of ownership also may be bigger, therefore, the member carrier that uses of CA terminal may and other system, for example TD-SCDMA, share frequency band or use adjacent frequency band, as shown in Figure 3.The LTE-A terminal resides in three sub-district: Cell1, Cell2 and Cell3, and wherein, Cell1 and Cell2 use Band1, and Cell3 uses Band2.For avoiding TDD system up-downgoing cross interference, Band1 should use the TDD UL/DL configuration mode that can coexist with 3G TDD Band A, and Band2 then should use the TDD UL/DL configuration mode that can coexist with 3G TDD Band B.If Band A is different with the TDD UL/DL configuration mode that Band B uses, then the TDD UL/DL configuration mode of Band1 and Band2 use is also inequality.If a terminal can take a plurality of Band, and different B and can support different TDD UL/DL configuration modes, and terminal can be used different transceivers at different B and.
In realizing process of the present invention, the inventor finds prior art, and there are the following problems at least:
LTE R10 only supports all identical scene of UL/DL configuration mode of a plurality of TDD sub-district that UE is resident, support the situation of different UL/DL configuration modes for different B and, if still according to the mechanism works of R10, UE can't obtain the UL/DL configuration mode on the TDD sub-district (mainly being auxilliary sub-district), and functions such as up-downgoing scheduling, HARQ feedback are produced harmful effect.
