Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of synchronizing information sending and receiving method, down control channel mapping and analytic method, ascending control information sending method.
Background technology
When terminal access LTE residential quarter, need through a series of cell search process.Through these, terminal just can be determined time and frequency parameter, and the uplink signal that has accurate timing for the descending control of demodulation, data channel signal and transmission is necessary, and terminal also can be obtained some system core parameters simultaneously.
The Cell searching flow process as shown in Figure 1, at first terminal detects master sync signal PSS and obtains cell set ID and physical layer time slot timing information, by SSS, detect and obtain residential quarter ID, CP type, radio frames timing information and dual-mode again, for the detection of downlink reference signal and broadcast channel PBCH provides prior information.After downlink reference signal and PBCH detected and complete, terminal had just completed time and the Frequency Synchronization with base station, and has obtained the system informations such as system bandwidth, System Frame Number, descending HARQ indicating channel resource information and transmitting antenna.Finally by the correct decoding to DSCH Downlink Shared Channel PDSCH, obtain the system configuration information that SIB message carries and complete cell search process.
Obviously, be synchronously a step of most critical in cell search process fast and accurately, the down-going synchronous of broad sense can be thought and also comprises the PBCH detection.In the LTE system, also fully take into account synchronous importance, adopted time diversity and diversity antenna technology to guarantee the correct reception of synchronizing signal.Fig. 2 has provided emission time domain, the frequency-domain structure figure of synchronizing signal and broadcast channel under the tdd mode, wherein at PBCH on frequency domain and PSS, SSS, all occupied near the 1.08MHz bandwidth the center frequency point, the purpose of design of this point is to consider the wide property of multi-band of LTE, LTE supports the terminal access residential quarter of the multiple different bandwidth of 20MHz～1.4MHz, even above-mentioned design can guarantee that the 1.4MHz bandwidth terminals also can the complete PSS of getting, SSS and PBCH signal, complete down-going synchronous and obtain system information.On time domain, 10ms is in the frame period, PSS and SSS signal repeat to send the acquisition time diversity twice, on the 0th, 5 subframes, send SSS respectively, 1st, on 6 subframes, send PSS, design had not only reduced the possibility that synchronizing signal that the radio propagation channel decline causes loses but also the quick 5ms access residential quarter that guaranteed terminal like this.From in the PSS/SSS frame, repeat different, LTE designs on the one hand PBCH and disperses each MIB of transmission at 40ms, the possibility of the MIB information drop-out that the decline of reduction radio propagation channel causes, also adopt multi-antenna emission diversity and forward error correction coding to promote the detection performance on the other hand.
Although LTE has adopted multiple technologies to guarantee the down-going synchronous performance, because wide support makes synchronizing signal and PBCH can only be fixed on the 1.08MHz emission of center frequency point annex to multi-band.If strong broad-band interference has just been covered this 1.08MHz bandwidth, so terminal must normal synchronized, separate MIB message, cause the terminal can't access network.
LTE meets the designing requirements such as the large capacity, high transfer rate large coverage of system, adopts the resource distribution of real-time configurable ground, system parameters etc.Obviously, the correct reception of above-mentioned configuration information is that terminal completes accurately, the prerequisite of high speed data transfer.LTE design base station configuration information is mainly carried by down control channel PDCCH, and control format indicating channel PCFICH carries the OFDM symbolic information that PDCCH takies, and descending HARQ indicating channel provides HARQ to feed back to terminal.Ascending control channel is mainly used in transmitting resource scheduling information and the ACK/NACK feedback messages such as CQI, PMI, RI.Although in Fig. 1 not the parsing to control channels such as PDCCH explain, it remains the prerequisite that correct parsing PDSCH carries SIB message.
For control channel, LTE has designed relatively-stationary position, as shown in Figure 3.Due to descending employing distributed resource allocation, to obtain frequency diversity, design (1～3) individual OFDM symbols carry PCFICH, PHICH and PDCCH that descending control area takies each descending sub frame; And ascending resource distributes the centralized frequency-hopping mode that adds of employing to obtain frequency diversity, and in order to guarantee the continuity of upstream data resource, the upload control zone concentrates on the edge band place.Although the frequency domain dispatching that the LTE system adopts makes up-downgoing shared channel PDSCH and PUSCH can well dodge interference, but distribute inflexible control channel for resource, in case disturbing appears in its control area, the means such as control channel repeated encoding that only depend on the LTE system are not enough to effectively to anti-interference, cause terminal can't obtain Downlink Control Information, and then correctly resolve PDSCH, perhaps base station can't obtain uplink feedback information, by flexible dispatching, makes PUSCH dodge interference.

[embodiment mono-]
In the present embodiment one, a kind of method of sending and receiving of synchronizing information is provided, by a plurality of ad-hoc locations in system bandwidth, has been formed for sending the frequency band of synchronizing signal and PBCH, while preventing that center frequency-band is disturbed, cause terminal can't obtain synchronizing information, be unfavorable for the problem of Cell searching.
The sending method of described synchronizing information comprises:
Base station obtains the current system condition;
During greater than particular value, base station a plurality of ad-hoc locations in system bandwidth are formed for sending the frequency band of synchronizing signal and PBCH when system bandwidth;
One or more frequency band of base station selection sends synchronizing signal and PBCH.
Concrete, the current system condition that base station obtains comprises: descending disturbed condition.In the present embodiment, described descending disturbed condition obtains by the following method: ascending time slot detects the uplink interference situation of each RB, and carries out the filtering processing, obtains the disturbance state of each RB, under tdd mode, can be equivalent to the descending identical interference that also is subject to.In addition, the current system condition obtained of base station also comprises: near the RB disturbed condition current system bandwidth and center frequency point.For down control channel and data channel, mapping obtains the special-purpose RBG BITMAP of interference of down control channel and downstream data channel interference RB BITMAP respectively.
In the present embodiment, the condition that base station a plurality of ad-hoc locations in system bandwidth are formed for sending the frequency band of synchronizing signal and PBCH comprises: near a plurality of RB center frequency point are interfered, and are preferred, and near continuous 6 RB center frequency point are interfered; Reach system bandwidth greater than particular value, preferred, described particular value is 10MHz.
At this, consider that synchronizing information (comprising synchronizing signal PSS, SSS and broadcast channel PBCH) has mainly occupied near 6 RB of center frequency point, therefore, in order to reduce the spending of system, (special when being preferably near center frequency point a plurality of RB and being interfered, when near 6 above RB center frequency point are interfered), ability a plurality of ad-hoc locations in system bandwidth are formed for sending the frequency band of synchronizing signal and PBCH.In other embodiment of the application, also can in the situation that near the RB center frequency point be not interfered, a plurality of ad-hoc locations are formed for sending the frequency band of synchronizing signal and PBCH in system bandwidth, this increase system spending of naming a person for a particular job, but it also can bring the advantage of order of diversity simultaneously, therefore, the application does not do restriction to this.
In the present embodiment, another condition that base station a plurality of ad-hoc locations in system bandwidth are formed for sending the frequency band of synchronizing signal and PBCH is: system bandwidth is greater than particular value, and special, described particular value is 10MHz.At this, to consider when system bandwidth is larger, the frequency band that utilizes in system bandwidth a plurality of ad-hoc locations to be formed for sending synchronizing signal and PBCH more can be saved frequency spectrum resource.In other embodiment of the application, also can in the situation that system bandwidth less in system bandwidth a plurality of ad-hoc locations be formed for sending the frequency band of synchronizing signal and PBCH, for example system bandwidth is in the situation of 5MHz, comparatively speaking, the frequency spectrum resource that it brings is saved not obvious, but does not hinder it as a kind of alternative.

Then, one or more frequency band of base station selection sends synchronizing signal and PBCH, namely chooses one or more ad-hoc location and sends synchronizing signal and PBCH.In the present embodiment, base station sends synchronizing signal and PBCH according to disturbing power to choose one or more ad-hoc location.Concrete, if choosing an ad-hoc location, base station sends synchronizing signal and PBCH, choose and disturb a minimum frequency band to send synchronizing signal and PBCH; If base station will be chosen two ad-hoc locations and send synchronizing signals and PBCH, choose and disturb minimum and time two little frequency bands send synchronizing signal and PBCH waits the like.In addition, base station also can directly send synchronizing signal and PBCH on the ad-hoc location of all formation, at this moment, can save base station scans to obtain the work of the signal disturbed condition on each ad-hoc location.When base station sends synchronizing signal and PBCH on a plurality of ad-hoc locations, terminal, when obtaining synchronizing signal and PBCH, will obtain selecting to merge gain.
In the present embodiment, for the situation of system bandwidth less than particular value (being preferably 10MHz), take following scheme to send synchronizing information: base station is chosen and is disturbed little frequency as new center frequency point in current available frequency band, in the 1.08MHz bandwidth of new center frequency point annex, send synchronizing signal and PBCH.At this, consider the system bandwidth less, the frequency spectrum resource waste less that frequency hopping causes, avoided forming a plurality of transmission synchronizing signals and PBCH frequency band and the problem of increase system spending simultaneously.
After base station has completed the transmission of synchronizing signal and PBCH, then, the reception of terminal for synchronizing information will be introduced.Wherein, terminal is corresponding for the transmission of synchronizing information with base station for the reception of synchronizing information.Please refer to Fig. 5, it is the terminal reception synchronizing signal of the embodiment of the present invention and the receive mode schematic diagram of PBCH, and is specific as follows:
When terminal was obtained system bandwidth greater than particular value, terminal detected ad-hoc location in system bandwidth;
The detected value that ad-hoc location detected when terminal is during greater than threshold value, and terminal is obtained synchronizing signal and PBCH on this ad-hoc location.
wherein, terminal can realize by two kinds of modes again for the decoding of synchronizing information: one, the detected value that an ad-hoc location detected when terminal is during greater than threshold value, terminal is obtained synchronizing signal and PBCH on this ad-hoc location, and terminal stops detecting, in case namely terminal detects a synchronizing information on ad-hoc location, terminal namely stops the detection of synchronizing information, in this kind implementation, can save the detection time of terminal for synchronizing information, they are two years old, the detected value that an ad-hoc location detected when terminal is during greater than threshold value, terminal is obtained synchronizing signal and PBCH on this ad-hoc location, and terminal continues to detect, until detected all ad-hoc locations, be that terminal will detect all ad-hoc locations, and obtain all synchronizing signals and PBCH, and the detected value that a plurality of ad-hoc locations detected when terminal is during greater than threshold value, terminal will be obtained on these a plurality of ad-hoc locations synchronizing signal and PBCH are by the order of diversity combination (wherein, pressing the order of diversity combination can be according to the signal to noise ratio size of each ad-hoc location, multiply by different coefficients, this is prior art, the application is not construed as limiting this), obtain final synchronizing signal and PBCH, in this kind implementation, terminal can obtain selecting to merge gain.
When terminal was obtained system bandwidth less than particular value, terminal can be by receiving the frequency handover information that Paging message is carried on Paging chance position, and after obtaining new frequency point information, residential quarter is reconstructed on new frequency, carries on business.At this moment, in the 1.08MHz bandwidth of new center frequency point annex, obtain synchronizing signal and PBCH.
