Description

A kind of distribution method of down control channel resources and device

Technical field

The present invention relates to moving communicating field, relate in particular to distribution method and the device of a kind of down control channel resources in mobile communication system.

Background technology

At third generation partner program (3rd Generation Partnership Project, 3GPP) Long Term Evolution (Long Term Evolution, LTE) or the senior evolution (LTE-advanced of LTE, LTE-A) in system, the downlink multi-access access way adopts multiple access access (Orthogonal Frequency Division Multiple Access, OFDMA) mode of OFDM usually.The downlink resource of system has been divided into orthogonal frequency division multiplexing multiple access (Orthogonal Frequency Division Multiple, OFDM) symbol from the time, from frequency, has been divided into subcarrier.Certain subcarrier in certain OFDM symbol is called resource element (Resource Element, RE).According to the standard of LTE version 8/9/10, a descending sub frame includes two time slots, and each time slot has 7 or 6 OFDM symbols, namely contains altogether 14 or 12 OFDM symbols.Wherein, while adopting normal Cyclic Prefix (Cyclic Prefix, CP) length, each time slot comprises 7 OFDM symbols, and while adopting the CP length of expanding, each time slot comprises 6 OFDM symbols.According to the standard of LTE version 8/9/10, defined Resource Block (Resource Block, RB), a RB comprises 12 subcarriers on frequency domain, be a time slot on time domain, namely comprises 7 or 6 OFDM symbols, and therefore a RB comprises 84 or 72 RE.On same sub-carrier in a subframe, a pair of RB of two time slots is referred to as RB couple, and namely Resource Block is to (RB pair).The various data of carrying on subframe are to mark off various physical channels to organize mapping on the physics running time-frequency resource of subframe.Various physical channels can be divided into two classes substantially: control channel and Traffic Channel.Correspondingly, the data of control channel carrying can be described as controls data or control information, and the data of Traffic Channel carrying can be described as business datum.in version 10 and LTE system before, Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) with Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) it is the time-division in a subframe, PDCCH is carried in front n OFDM symbol of a subframe, wherein, n can be 1, 2, 3, any one in 4, and by Physical Control Format Indicator Channel (Physical Control Format Indicator Channel, PCFICH) determine, breaing up on the whole system bandwidth after by interleaving treatment on frequency domain, to obtain frequency diversity gain, the downlink data of its scheduling is from n+1 sign-on mapping of this subframe.subscriber equipment (User Equipment, UE) based on the specific reference signal in residential quarter (Cell-specific reference signals, CRS) magnitude of load and the polymerization level according to PDCCH carried out demodulation to PDCCH in the search volume of PDCCH, after decoding, with the specific Radio Network Temporary Identifier of this UE (Radio Network Temporary Identity, RNTI) descrambling cyclic redundancy check (CRC) code (Cyclic Redundancy Check, CRC) carry out the PDCCH of verification and definite this UE oneself, and according to the schedule information in this PDCCH, its data of dispatching are done corresponding reception or transmission processing.A complete PDCCH is comprised of one or several control channel element (Control Channel Element, CCE), and a CCE is comprised of 9 resource element groups (Resource Element Group, REG), and a REG accounts for 4 RE.Can be formed by 1,2,4 or 8 CCE according to 8/9/10, one PDCCH of LTE version.

in LTE system after version 10, multi-user's multiple-input and multiple-output (Multiple-Input Multiple-Out-put, MIMO) and collaborative multicast communication (Coordinated Multiple Points, CoMP) etc. the introducing of technology makes the control channel capacity limited, therefore can introduce the PDCCH that transmits based on MIMO precoding mode, this PDCCH can be based on the specific reference signal of UE (UE-specific reference signals, DMRS) carry out demodulation, call Physical Downlink Control Channel (the enhance Physical Downlink Control Channel of enhancing in the following text, ePDCCH), accordingly, the Physical Control Format Indicator Channel of a kind of enhancing of definable (enhance Physical Control Format Indicator Channel, ePCFICH).EPDCCH is in the control area of front n symbol of a subframe, but in the zone of the transmitting downlink data of this subframe, and with PDSCH be frequency division, can take different RB from PDSCH.In LTE version 11, the ePDCCH reference signal is that the reference signal of the PDSCH of the multiplexing transmission mode 9 that defines in version 10 is the DMRS structure, and can use the reference signal of 4 DMRS ports, i.e. DMRS port 7,8,9 and 10.

According to the mapping mode of ePDCCH, ePDCCH can be divided into ePDCCH and the distributed ePDCCH of local formula.To the ePDCCH of local formula, ePDCCH concentrates and to be mapped in a PRB or adjacent PRB, and base station can be reported according to the channel status of UE like this, and the selective channel condition is the upper ePDCCH that sends of PRB preferably, thereby obtain frequency scheduling, gains.To distributed ePDCCH, ePDCCH disperses to be mapped on a plurality of PRB, thereby can obtain the benefit of frequency diversity.Below as can be known, systematically the PDCCH resource is by time-multiplexed mode and PDSCH co-operation, and the PDCCH resource shows indication by the PCFICH channel.And the ePDCCH resource is mode and PDSCH co-operation by frequency division multiplexing.When ePDCCH resource and PDCCH resource were present in system simultaneously, the configuration information of ePDCCH, be also that resource information can transmit radio resource control (Radio Resource Control, RRC) message arrangement by the signaling of PDCCH.But under the self-existent scene of ePDCCH resource, namely when there is not the PDCCH resource in system yet, the collocation method of ePDCCH resource or discloses unsettled problem.
