Description

The recognition methods of carrier type and equipment

Technical field

The present invention relates to wireless communication field, relate in particular to a kind of recognition methods and equipment of carrier type.

Background technology

In long-term evolution upgrading (Long Term Evolution-Advanced, LTE-A) system, the peak rate of system has huge raising than Long Term Evolution (Long Term Evolution, LTE) system, requires to reach descending 1Gbps, up 500Mbps.Therefore, the LTE-A system needs the terminal extension available bandwidth, be about under same base station (eNB) a plurality of continuous or discrete carrier aggregation together, be subscriber equipment (User Equipment simultaneously, UE) service, to provide required speed, as shown in Figure 1.These carrier waves that condense together are called again member carrier (Component Carrier, CC).Each residential quarter can be a member carrier, and the residential quarter under different e NB (member carrier) can not polymerization.In order to guarantee that the UE in the LTE system can be in the carrier wave work of each polymerization, each carrier wave maximum is no more than 20MHz.

Downlink reference signal in the LTE-A system mainly comprises the exclusive reference signal in residential quarter (Cell-specific Reference Signals, CRS), downlink user DRS (Dedicated Reference Signal) (UE-specific Reference Signal, URS, perhaps also referred to as Downlink or Dedicated Reference Signal, DRS), location reference signals (Positioning Reference Signal, PRS), channel state information reference signals (Channel State Information Reference Signal, CSI-RS).

CRS supports 1,2,4 antenna port transmission, be mainly used in the data demodulates of down channel, and at each descending sub frame, there is transmission, at a Physical Resource Block (Physical Resource Block, PRB) mapping mode in as shown in Figure 2 a and 2 b, Fig. 2 a is the mapping mode under regular circulation prefix (Cyclic Prefix, CP), and Fig. 2 b is the mapping mode under expansion CP.CRS produces based on pseudo random sequence c (i), following formula (1), c (i) at each OFDM (Orthogonal Frequency Division Multiplexing, OFDM) symbol based on time-gap number n _s, OFDM symbol number l, cell ID

And the relevant parameter N of cyclic prefix type during _CPCarry out initialization, the CRS sequence of namely transmitting on each OFDM symbol is different, as shown in Equation (2).CRS sequence corresponding to 1 OFDM symbol is based on maximum bandwidth

(be generally 20MHz,, take Physical Resource Block (PRB) as unit, be 110PRB) in the CRS symbol numbers that needs on 1 antenna port produce, the single antenna port comprises 2 CRS symbols in a PRB on an OFDM symbol, therefore, the sequence length of CRS generation is This CRS sequence is mapped on each PRB in maximum bandwidth according to maximum bandwidth, if current downlink system bandwidth less than maximum bandwidth, actual use be CRS in PRB corresponding to the current downlink system bandwidth that is mapped to maximum bandwidth frequency band central authorities.

DRS supports 1 ~ 8 antenna port transmission, only in the upper transmission of the PRB at the downlink data place of adopting transmission mode 7 ~ 9.Version 10(Rel-10) regulation in, at DRS and Physical Broadcast Channel (Physical Broadcast Channel, PBCH) or synchronizing signal exist in same subframe in the overlapping PRB of resource, DRS does not send, therefore the downlink data based on the DRS demodulation can not be transmitted in these PRB, but the downlink data based on the CRS demodulation can be transmitted.

Cell searching is the first step that UE is linked into a residential quarter, and by this process, UE can obtain with the down-going synchronous that accesses residential quarter, obtain cell identity information (residential quarter ID) and residential quarter relevant configuration information, to guarantee the normal operation of UE in this residential quarter.Mainly comprise synchronization signal detection and the PBCH of Cell searching receive.

Synchronizing signal comprises master sync signal (Primary Synchronized Signal, PSS) and auxiliary synchronous signals (Secondary Synchronization Signal, SSS), be used for carrying out descending timing, find the radio frames original position to carry out digital received and sent.PSS and SSS only upload defeated (actual take 62 subcarriers, all the other subcarriers are as the protection interval) at 72 subcarriers of subdistrict frequency band central authorities.for the frame structure Class1, i.e. the frame structure of Frequency Division Duplexing (FDD) (Frequency Division Duplex, FDD) system, PSS and SSS transmit respectively on last and penultimate OFDM symbol of time slot 0 and 10, for frame structure type 2, be time-division duplex (, Time Division Duplex, TDD) frame structure of system, PSS transmits on the 3rd OFDM symbol of subframe 1 and 6, wherein subframe 1 is special subframe, comprise descending pilot frequency time slot (Downlink Pilot Time Slot, DwPTS), guard time (Guard Period, GP) and uplink pilot time slot (Uplink Pilot Time Slot, UpPTS), subframe 6 is only at 5 milliseconds of (Millisecond, ms) be special subframe in the configuration of the TDD up/down row of descending-up switching point, SSS transmits on last OFDM symbol of time slot 1 and 11, as shown in Figure 3 a and Figure 3 b shows, Fig. 3 a is the resource mapping schematic diagram of the synchronizing signal of FDD system, Fig. 3 b is the resource mapping schematic diagram of the synchronizing signal of TDD system.

PBCH is used for carrying Master Information Block (Master Information Block, MIB), mainly carry: the downlink system bandwidth of this residential quarter, physical mixed automatic repeat request indicating channel (Physical HARQ Indication Channel, PHICH) configuration and System Frame Number (System Frame Number, SFN).In addition, the different scrambling sequence of the cyclic redundancy check (CRC) of PBCH (Cyclic Redundancy Check, CRC) information use has been indicated the CRS antenna port number of base station.UE, by the scramble sequence of the CRC of blind check PBCH, can obtain this antenna port number.Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH), the channel such as PHICH, Physical Control Format Indicator Channel (Physical Control Format Indicator Channel, PCIFCH) all uses this CRS antenna port number transmission.PBCH upgrades take 40ms as the cycle, transmit on front four OFDM symbols of the 2nd time slot (being time slot 1) of the subframe 0 of each radio frames in 4 continuous radio frames, fixedly take 72 subcarriers of carrier frequency band central authorities on frequency domain, as shown in Fig. 4 a and Fig. 4 b, wherein, Fig. 4 a is the mapping mode under conventional CP, as Fig. 4 b, is the mapping mode under expansion CP.

In order further to improve resource utilization ratio, the version 11(Rel-11 of LTE-A system) determine to introduce new carrier type (Additional Carrier Type or New Carrier Type, NCT), with strengthen the system spectrum utilance, better support heterogeneous network, reduce power consumption.The NCT carrier wave only supports that 5ms is single antenna port (antenna port 0) the CRS transmission in cycle, and CRS is not used in the downlink data demodulation.In Rel-11, the NCT carrier wave can not work alone, and needs and the associated working of a tradition (legacy) carrier wave.Whether have certain deviation with the legacy carrier wave on time domain and frequency domain according to receiving terminal, be divided into sync carrier and asynchronous carrier wave, the latter need to carry out independent Time and Frequency Synchronization and process, so needs synchronous signal transmission on the NCT carrier wave.Consider that the downlink data on the NCT carrier wave needs based on the DRS demodulation, and on the legacy carrier wave, synchronizing signal and DRS exist resource overlapping,, in order to improve the down transmission efficiency of NCT carrier wave, need the new synchronous transmission of signal time-domain position of design to avoid overlapping with the resource of the downlink reference signals such as CRS and DRS.In addition, in Rel-12 and later release, the NCT carrier wave also may work alone, and therefore, also needs to transmit PBCH, and the PBCH transmission should avoid overlapping with the resource of the downlink reference signals such as CRS and DRS equally.

Synchronous transmission of signal resource on the NCT carrier wave is different from the legacy carrier wave, UE is when can not determine that its access carrier is NCT carrier wave or legacy carrier wave, can't obtain correct synchronization signal data, and then can't correctly receive PBCH, can not realize normal cell search process.

Concrete, in step 51, terminal, according to the PBCH that detects, is determined the carrier type of current carrier wave, specific implementation can adopt one of following three kinds of modes:

Mode one: the type of the restituted signal that uses according to the PBCH that detects, determine the carrier type of current carrier wave;

Concrete,, if the restituted signal that the PBCH that detects uses is the exclusive reference signal in residential quarter (CRS), determine that current carrier wave is first kind carrier wave; , if the restituted signal that the PBCH that detects uses is downlink user DRS (Dedicated Reference Signal) (DRS), determine that current carrier wave is the Equations of The Second Kind carrier wave.

Mode two:, according to time domain and/or the frequency domain resource at the PBCH place that detects, determine the carrier type of current carrier wave;

Concrete,, if meet the following conditions five and/or condition six, determine that current carrier wave is first kind carrier wave; Otherwise, determine that current carrier wave is the Equations of The Second Kind carrier wave; Wherein:

Scheme two: according to the OFDM symbol at the synchronizing signal place that the detects OFDM symbol with the CRS place that detects, the position relationship of the transmission sequence on time domain or place time slot or the position relationship of place subframe, determine the carrier type of current carrier wave;

, if there is simultaneously the symbol of the OFDM symbol at leading and the backward PSS place that detects in the OFDM at the CRS place that detects, determine that current carrier wave is first kind carrier wave; Otherwise, determine that current carrier wave is the Equations of The Second Kind carrier wave; Perhaps,

, if there is simultaneously the symbol of the OFDM symbol at leading and the backward SSS place that detects in the OFDM at the CRS place that detects, determine that current carrier wave is first kind carrier wave; Otherwise, determine that current carrier wave is the Equations of The Second Kind carrier wave; Perhaps,

This is because on the legacy carrier wave, CRS transmits in each subframe, there is transmission to I haven't seen you for ages on the OFDM of synchronizing signal front and back symbol, and on the NCT carrier wave CRS take 5ms as periodic transfer,, if predesignate on the NCT carrier wave CRS and synchronizing signal not in same subframe, can judge carrier type according to whether CRS all being detected on the OFDM of synchronizing signal front and rear symbol.

Scheme three: according to the OFDM symbol at the synchronizing signal place that detects and the OFDM symbol at the CRS place that detects, the OFDM symbol numbers at interval on time domain, and, the OFDM symbol at the OFDM symbol at the synchronizing signal place that detects and the CRS place that detects, the position relationship of the position relationship of the transmission sequence on time domain or place time slot or place subframe, determine the carrier type of current carrier wave;

Wherein, synchronizing signal comprises PSS and/or SSS.

Scheme four: whether identical with the subframe at the CRS place that detects according to the subframe at the synchronizing signal place that detects, determine the carrier type of current carrier wave;

Concrete,, if the subframe at the synchronizing signal place that detects is identical with the subframe at the CRS place that detects, determine that current carrier wave is first kind carrier wave; Otherwise, determine that current carrier wave is the Equations of The Second Kind carrier wave.This be because, on the legacy carrier wave, there is transmission in CRS in each subframe, CRS is only take 5ms as periodic transfer on the NCT carrier wave,, if CRS and the synchronizing signal predesignated on the NCT carrier wave are not transmitted in same subframe, can judge carrier type by whether UE detects simultaneously in same subframe synchronizing signal and CRS.
