Description
Technical field
The present invention relates to LTE(Long Term Evolution, Long Term Evolution) mobile communication system technical field, particularly a kind of Physical Downlink Control Channel blind Detecting implementation method, device and subscriber equipment.
Background technology
3GPP(3rd Generation Partnership Project, third generation partner program) LTE system is 3G(3rd Generation, 3-G (Generation Three mobile communication system)) Long Term Evolution version.LTE system is compared existing GSM(Global System for MobileCommunications, global system for mobile communications), WCDMA(Wideband CodeDivision Multiple Access, Wideband Code Division Multiple Access (WCDMA)), the mobile communication system such as CDMA2000, provide higher user's peak rate, larger coverage and better community user QoS(Quality of Service, service quality) etc.LTE-A(LTE-Advanced, LTE evolution) system is the enhancing version of LTE, proposes more competitive system performance index.
LTE and lte-a system descending employing OFDMA(Orthogonal FrequencyDivision Multiple Access, OFDM) technology, the SC-FDMA(Single Carrier-Frequency Division MultipleAccess that peak-to-average force ratio is lower is adopted, single-carrier frequency division multiple access at up direction) technology.In addition, the multi-antenna technology MIMO(Multiple Input Multiple Output adopted in system, multiple-input and multiple-output) provide spatial multiplex gains and emission diversity gain.Therefore, LTE and lte-a system available resources comprise the dimensions such as time domain, frequency domain and spatial domain, base station is by scheduling and resource allocation algorithm, based on the channel information of intra-cell users flexibly reasonably for user distributes suitable time slot, PRB(Physical Resource Block, Physical Resource Block), MCS(Modulation andCoding Scheme, modulating-coding form), transmitting power, MIMO transmission scheme etc., to improve throughput of system, meet the rate requirement of Cell Edge User simultaneously.
In LTE and lte-a system, the control signal information of down channel with various types of DCI(Downlink Control Information, Downlink Control Information) transmit, these DCI are carried by PDCCH.
In the 10ms frame structure of LTE and lte-a system definition, the corresponding TTI(Transmission Time Interval of 1ms descending sub frame, Transmission Time Interval).In a TTI, PDCCH time domain takies front n(n<=3) individual OFDM(OrthogonalFrequency Division Multiplexing, OFDM) symbol, frequency domain takies whole system bandwidth.Other channel comprises as reference signal, PCFICH(PhysicalControl Format Indicator Channel, Physical Control Format Indicator Channel), PHICH(Physical HARQ Indicator Channel, Physical HARQ Indicator Channel) etc.Therefore, in each of the lower in row subframe, only have the reserved running time-frequency resource of limited quantity to can be used for transmitting Downlink Control Information, the PDCCH namely carrying DCI information can be very limited with running time-frequency resource.
The least unit that PDCCH resource is distributed is CCE(Control Channel Element, control channel element), 1 CCE comprises 9 REG(Resource Element Group, resource element group), and a REG comprises 4 RE(Resource Element, resource element), therefore a CCE contains 36 RE.LTE and LTE-A standard regulation allows CCE to have four kinds of AL(Aggregation Level, polymerization grade), AL=1,2,4 and 8, a corresponding PDCCH channel takies 1,2,4 or 8 CCE simultaneously respectively.
Different according to the DCI type of transmission, PDCCH comprises two class search volumes: CSS(Common Search Space, public search space) and USS(UE-specific SearchSpace, user-specific search volume).CSS position is fixing, place common detection information, and USS is for transmitting the information relevant to individual user, and the resource mapping in this space needs to carry out PDCCH resource distribution by base station to the user dispatched in community and determines.In this two classes search volume, user adopts the DCI information in blind checking method demodulation PDCCH, each UE(User Equipment, subscriber equipment) monitor the PDCCH Candidate Set in the USS of community simultaneously and carry out trial demodulation one by one.
In each TTI, UE does not also know which type of Downlink Control Information eNB will send, and not know that in this TTI it needs the DCI format received namely, equally do not know that its DCI is transmitted by the resource of what polymerization grade yet, therefore at each TTI, UE needs to carry out blind Detecting, is about to search for completely all possible situation (namely each PDCCH candidate) successively, to obtain the DCI information that it needs.Following regulation is had to the number of times that each UE carries out blind Detecting in standard:
Table 1
Can see, if searched for completely, each UE at each TTI according to its transmission mode, two kinds of DCI format may be had descending, and UE needs to carry out blind Detecting to 22 PDCCH candidates, namely UE needs at most blind Detecting 44 times, and its blind Detecting number of times is considerable.On the other hand, current UE is according to AL=1 when detection PDCCH, the order of 2,4,8 carries out blind Detecting, therefore when channel conditions is general, if also detected according to this order, computational resource will be wasted, because eNB is when channel conditions is general, very large probability can with AL=4,8 transmission PDCCH.In LTE system, it is too much that UE carries out blind Detecting number of times, the time delay of system acceptance and process downlink information can be caused to increase, if UE carries out a lot of number of times blind Detecting at every TTI simultaneously, also the electricity that it is too much is consumed, because most UE needs powered battery, electricity is limited, and therefore consumes power has directly had influence on Consumer's Experience.
