Description
Technical field
The present invention relates to the administrative skill of component carrier in carrier aggregation system, particularly relate to the carrier management method determining dependence between subscriber equipment (UE, UserEquipment) component carrier in a kind of carrier aggregation system.
Background technology
Long Term Evolution (LTE, LongTermEvolution) Frequency Division Duplexing (FDD) (FDD in system, FrequencyDivisionDuplex) version 8 of system is single-carrier system, within the system, up-link carrier and descending carrier only have a pair, therefore the descending carrier required for up-link carrier is unique, and the up-link carrier required for descending carrier is also unique.Under default condition, be defaulted as dependence between the two.The version 10 of the FDD system in long evolving system, i.e. advanced long-term evolution system is multicarrier system, runs multiple up-link carrier and multiple descending carrier in network, and according to current correlation standard, network can support at most 5 descending carriers.Subscriber equipment can configure multiple up-link carrier and multiple descending carrier simultaneously.Under default condition, between up-link carrier and descending carrier, there is no the dependence given tacit consent to.Therefore, carry out, in the process communicated, needing to determine dependence between the up-link carrier of subscriber equipment and descending carrier at subscriber equipment and network.Dependence between this carrier wave is the precondition ensureing subscriber equipment and network proper communication.The prerequisite of proper communication comprises: the dependence between the descending carrier at the up-link carrier at (1) clear and definite Random Access Channel (RACH, RandomAccessChannel) place and the response place of Stochastic accessing; (2) clearly for the Uplink Shared Channel (UL-SCH of transmitting uplink data, Uplink-SharedChannel) place up-link carrier and carrying physical mixed automatic repeat request indicating channel (PHICH, PhysicalHARQIndicatorChannel) descending carrier between dependence; (3) DSCH Downlink Shared Channel (DL-SCH of clear and definite downlink data transmission, Downlink-SharedChannel) place descending carrier and carrying Physical Uplink Control Channel (PUCCH, PhysicalUplinkControlChannel) up-link carrier between dependence; Etc..Dependence between above-mentioned may be summarized to be: DL relies on UL, or UL relies on DL.
Therefore, before realizing subscriber equipment and network-side communication, need to carry out clearly, to prevent the dependence ambiguity in communication process to the dependence of up-link carrier and descending carrier.Here, rely on ambiguity and refer to, at a time, the dependence carrier wave of up-link carrier is not specified, or the dependence carrier wave of up UL-SCH has multiple; Or at a time, the dependence carrier wave of descending carrier is not specified, or the dependence carrier wave of descending carrier has multiple.
In the version 10 of FDD system, do not provide how to determine subscriber equipment configure dependence between carrier wave, during practice, the dependence ambiguity of up-link carrier and descending carrier will be caused, thus affect the communication quality of subscriber equipment.Therefore, be necessary dependently between clear and definite carrier wave to determine mode.
