Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of processing method and system of Downlink Control Information.
Background technology
Radio frames (radio frame) in Long Term Evolution (LTE, the Long Term Evolution) system comprises the frame structure of FDD (FDD, Frequency Division Duplex) pattern and time division duplex (TDD, TimeDivision Duplex) pattern.In the frame structure of fdd mode, the radio frames of 10 milliseconds (ms) is that 0.5ms, numbering from 0 to 19 time slot (slot) are formed by 20 length, and time slot 2i and 2i+1 composition length are subframe (subframe) i of 1ms.In the frame structure of tdd mode, the radio frames of a 10ms is longly formed for the field of 5ms (half frame) by two, and a field comprises that 5 length are the subframe of 1ms, and subframe i is defined as 2 and longly is time slot 2i and the 2i+1 of 0.5ms.In above-mentioned two kinds of frame structures; For standard cyclic prefix (Normal CP, Normal Cyclic Prefix), the symbol that it is 66.7 microseconds (us) that time slot comprises 7 length; Wherein the CP length of first symbol is 5.21us, and the length of all the other 6 symbols is 4.69us; For extended cyclic prefix (Extended CP, Extended CyclicPrefix), a time slot comprises 6 symbols, and the CP length of all symbols is 16.67us.
The version number of LTE corresponding to version (Release, R) 8, it increases the corresponding version number of version is R9 (Release 9).Following three kinds of downlink physical control channels have been defined among the LTE: physical down control format indicating channel (PCFICH, Physical Control Format Indicator Channel); The automatic repeat requests indicating channel of physical mixed (PHICH, Physical Hybrid Automatic Retransmission RequestIndicator Channel); Physical Downlink Control Channel (PDCCH, Physical Downlink ControlChannel).
Wherein, The PCFICH loaded information is used in reference to the OFDM (OFDM that is shown in transmission PDCCH in the sub-frame; Orthogonal Frequency Division Multiplexing) number of symbol; On first OFDM symbol of subframe, send, the place frequency location by system descending bandwidth and cell ID (ID, Identity) definite.
PHICH is used to carry acknowledgement/non-acknowledgement (ACK/NACK) feedback information of uplink transmission data.The number of PHICH, time-frequency position can be definite with sub-district ID by the system message in the Physical Broadcast Channel (PBCH, Physical Broadcast Channel) of the descending carrier at PHICH place.
PDCCH is used for bearing downlink control information (DCI, Downlink Control Information), comprising: uplink and downlink schedule information, and uplink power control information.The form of DCI (DCI format) is divided into following several kinds: DCI format 0, DCI format 1, DCI format 1A, DCI format 1B, DCI format 1C, DCI format 1D, DCI format 2, DCI format 2A, DCI format 3 and DCI format 3A etc.; Wherein:
DCI format 0 is used to indicate the scheduling of Physical Uplink Shared Channel (PUSCH, Physical Uplink SharedChannel);
DCI format 1, DCI format 1A, DCI format 1B, DCI format 1C, DCI format1D are used for the different mode of a PDSCH code word scheduling;
DCI format 2, DCI format 2A are used for the different mode of space division multiplexing;
DCI format 3, DCI format 3A are used for the different mode of the power control instruction of Physical Uplink Control Channel (PUCCH, PhysicalUplink Control Channel) and PUSCH.
The physical resource of physical downlink control channel PDCCH transmission is with control channel element (CCE; ControlChannel Element) is unit; The size of a CCE is 9 resource element group (REG; ResourceElement Group), i.e. 36 resource elements (Resource Element), a PDCCH possibly take 1,2,4 or 8 CCE.These four kinds of PDCCH sizes for taking 1,2,4,8 CCE adopt tree-shaped polymerization (Aggregation), and the PDCCH that promptly takies 1 CCE can begin from any CCE position; The PDCCH that takies 2 CCE begins from even number CCE position; The CCE position of the integral multiple of the PDCCH that takies 4 CCE since 4; The CCE position of the integral multiple of the PDCCH that takies 8 CCE since 8.In a radio frames; If adopt conventional CP (Cyclic Prefix; Cyclic Prefix); Can carry the physical resource of PDCCH on preceding 1 to 3 OFDM symbol of first time slot of each subframe, and physical resource that can bearing downlink shared channel (PDSCH, PhysicalDownlink Shared Channel) on the remaining symbol.
To each polymerization grade (Aggregation level) definition search volume (Search space), comprise the search volume of public (common) and the search volume of subscriber equipment (UE, User Equipment) proprietary (UE-Specific).OFDM symbolic number that the controlled area that the CCE number of whole search volume is indicated by PCFICH in each descending sub frame is shared and the group number of PHICH are confirmed.UE DCI format by transmission mode of living in the search volume carries out blind Detecting to all possible PDCCH code check.
