Description
Technical field
The application relates to communication technical field, more specifically, relates to a kind of method that down control channel resources distributes.
Background technology
Supporting that, in senior Long Term Evolution (LTE-A) system of carrier aggregation, scheduling authorization is supported two kinds of send modes, i.e. this carrier dispatching and across carrier dispatching.This carrier dispatching (SCC) back compatible REL-8/9 agreement, the descending distribution of a carrier wave and uplink authorization are by Physical Downlink Control Channel (PDCCH) scheduling of this carrier wave.Across carrier dispatching (CCC): the descending distribution of a carrier wave and uplink authorization can be dispatched by the PDCCH of other carrier waves.
In Rel-10 agreement, main carrier (PCC) must adopt this carrier dispatching.If the multiple carrier waves of UE polymerization (CC) can adopt across carrier dispatching on SCC.One by the SCC across carrier dispatching, and its scheduling CC can be PCC, can be also other SCC.
UE is by the SCC across carrier dispatching
xupper reception Physical Downlink Shared Channel (PDSCH), first will obtain two information, and one is that instruction UE is at SCC
xthe upper frequency domain resource position of distributing of PDSCH and the down link control information (DCI) of modulation coding mode (MCS), another is that UE is at SCC
xon PDSCH primary sign positional information.Rel-10 realizes in the following ways:
First DCI information: UE will monitor the Physical Control Format Indicator Channel (PCFICH) of scheduling on CC, obtains the symbolic number that the PDCCH of this scheduling CC takies, and then the PDCCH of this CC is carried out to blind Detecting, and then obtains its DCI information corresponding on SCCx.
PDSCH primary sign positional information on SCCx: inform UE by RRC reallocation message.
Adopt across after carrier dispatching, the PDSCH resource of a CC can also can be dispatched by other CC by this CC scheduling.Therefore on the descending sub frame of a CC, may not only there is the UE of this carrier dispatching but also have the UE across carrier dispatching.Be that UE1 adopts intersection carrier dispatching referring to the left figure of accompanying drawing 1, UE1 is notified by RRC the PDSCH primary sign position on CC2; Right figure is that UE2 adopts this carrier dispatching, and the symbolic number that UE2 control information takies obtains by PCFICH.
The PDCCH adopting in LTE-REL8/9 system takies orthogonal frequency division multiplexi (OFDM) symbolic number dynamic adjustment algorithm, can reduce the expense of PDCCH channel on to the basis of PDCCH demand meeting system as far as possible, thereby improve the downlink resource utilance of system.
Because the PDSCH primary sign position across carrier dispatching UE obtains by RRC message, RRC message belongs to high-level signaling, obtained and can not be sent in time in corresponding subframe across the PDSCH primary sign position of carrier dispatching UE by RRC message, the OFDM symbolic number that therefore can not take PDCCH is dynamically adjusted timely.So in LTE-REL8/9, PDCCH takies the algorithm that OFDM symbolic number dynamically adjusts and can not be applicable to, and dispatches the LTE-A system across carrier dispatching user and this carrier dispatching on a PDSCH simultaneously.

Are method flow schematic diagrames that down control channel resources distributes referring to accompanying drawing 2, specifically comprise the following steps: be called UE1 for the user across carrier dispatching in the present invention, the user of local scheduling is called UE2.UE1 can comprise multiple users, and UE2 can comprise multiple users.
201, numerical value A corresponding to the position of the initial OFDM symbol of the PDSCH of UE1, judges whether A equals the configurable minimum value of OFDM symbol of Physical Downlink Control Channel (PDCCH).
PDCCH takies 1-4 OFDM symbol, includes the PDSCH that takies multiple OFDM symbols after PDCCH.
When there is UE1 and UE2 on a PDSCH time, first judge whether A equals the configurable minimum value of OFDM symbol of PDCCH simultaneously.According to agreement regulation, in the time that a descending sub frame sends PDCCH, if system bandwidth is less than or equal to 10 Resource Block, the configurable minimum value of OFDM symbol is 2 OFDM symbols; If system bandwidth is more than or equal to 10 Resource Block, the configurable minimum value of OFDM symbol is 1 OFDM symbol.
