Description
Technical field
The present invention relates to mobile radio communications system, particularly relate to a kind of method of reseptance and equipment that is used for the soft merging of paging receiving channel in the ofdm system.
Background technology
Now, third generation partner plan (being called for short 3GPP) standardization body has set about beginning its existing system standard is carried out long-term evolution (LTE).About the discussion of LTE, OFDM (OFDM) technology will be as the down physical layer transmission technology among the LTE according at present, and single-carrier frequency division multiple access insert (being called for short SC-FDMA) will be as the upstream physical layer transmission technology among the LTE.
Be a kind of multi-carrier modulation communication technology on the OFDM technological essence, its basic principle is the data flow of a two-forty to be decomposed into several rate data streams transmit simultaneously on one group of mutually orthogonal subcarrier.The OFDM technology is because its multicarrier character has performance advantage aspect a lot.(1) significant advantage of OFDM technology is because data parallel transmission on a plurality of subcarriers respectively, and the length of the symbol on each subcarrier increases accordingly, has alleviated because channel delay brings the influence of intersymbol interference; Add protection on each symbol at interval by further giving, promptly introduce Cyclic Prefix (CP), under the situation of channel delay, can eliminate intersymbol interference (ISI) fully less than circulating prefix-length.Like this, each subcarrier has all experienced flat fading channel.(2) availability of frequency spectrum height of OFDM technology, ofdm signal are actual on frequency domain an overlapping, and this overlapping on improved the availability of frequency spectrum to a great extent.(3) ability of the anti-narrow band interference of OFDM technology and frequency selective fading is stronger.By with chnnel coding and being used in combination of interweaving, can strengthen the frequency diversity and the time diversity effect of ofdm system, thereby resist narrow band interference and frequency selective fading effectively.(4) OFDM technology modulation and demodulation can be realized by baseband I FFT/FTT conversion, and IFFT/FFT has ripe quick calculation method, can realize in dsp chip and hardware configuration easily.
The communication system of LTE also needs paging channel, to realize the paging to subscriber equipment.According to the discussion among the present LTE, the control information relevant with paging comprises two parts, and promptly (Paging Indicator, PI) and paging information (Paging Information), the control information relevant with paging as shown in Figure 1 for paging indication information.
Wherein, the control information that comprises of paging indication information has:
Group identifier (Group ID): the user who is used to indicate needs to receive follow-up paging channel PCH organizes;
Map information (Mapping Information): the residing position of paging channel PCH that is used to indicate the needs decoding.
The control information that paging information comprised has:
Subscriber equipment identifier (User ID): the identifier that is used to indicate the subscriber equipment of base station institute paging.In the W-CDMA system, use user's interim identification code (Temporary MobileSubscriber Identity, TMSI) or international mobile subscriber identity (InternationalMobile Station Identity is IMSI) as the identifier of subscriber equipment.
Reason identifier (Cause ID): the reason that is used to indicate pagings such as type of service.
Paging has two kinds of channels to finish as can be seen, and a kind of is the channel of transmission PI, and another is the paging channel PCH of transmitting paging information.
According to the discussion among the present LTE, the channel of transmission PI can have two kinds, and a kind of is descending one deck/two layer (L1/L2) control channel, and another kind is the independently channel PICH of transmission PI.Utilize this two kinds of Channel Transmission PI, characteristics separately are:
● descending L1/L2 control channel
●PICH
At present, have company to propose will be under receiving same base station to adopt when the channel of transmission PI and PCH on the different sectors mode of soft merging, the soft merging mode that it proposed is specific as follows:
For the channel of transmission PI, require:
The channel of transmission PI information is a synchronous transmission on each sector under the same base station;
The PI information of transmitting on each sector under the same base station is identical, that is to say that the paging group identifier of transmission and indicated PCH resource information are identical;
The employed running time-frequency resource of channel of transmission PI information is identical on each sector under the same base station;
The employed scrambler of transmission PI information is all identical with orthogonal sequence on each sector under the same base station.
For PCH, require:
Transmission PCH is a synchronous transmission on each sector under the same base station;
On each sector under the same base station among the PCH transmitting paging information identical;
The employed running time-frequency resource of transmission PCH is identical on each sector under the same base station;
The employed scrambler of transmission PI information is all identical with orthogonal sequence on each sector under the same base station.
After above-mentioned constraints had been arranged, (Single Frequency Network, SFN) soft merging mode had received the transmission channel of PI and PCH channel just can to adopt single frequency network in the paging information receiving course.
Although adopt the soft merging mode of SFN can obtain bigger receiving gain,, therefore can have influence on the transmission of other data services because its constraints is more.
Adopt the soft merging mode of SFN, need to guarantee under the same base station that the shared running time-frequency resource of PCH transmission in each sector is identical.Yet owing to have different loads on the different districts under the same base station, the user that the user of different high-speed mobile and low speed move, if the transfer resource of priority allocation PCH, the user that must have a lot of downlink data transmission so can't guarantee to assign to optimum frequency resource; And if the employed frequency resource of priority allocation transfer of data user is difficult to so again guarantee that PCH is transmitted in each sector under the same base station on same running time-frequency resource, make that the soft merging of SFN is difficult to use.
In addition, because therefore the PCH channel is difficult to adopt local formula (Localized) transmission of frequency selectivity gain, and can uses distributed (distributed) transmission not from the channel quality report of subscriber equipment.Yet for the distributed transmission based on Resource Block pattern (Block Wised), the shared subcarrier of distributed transmission depends on the number N D of the Resource Block of total virtual distributed transmission
VRB, therefore owing to have different N in the different sectors under same base station
DVRBDemand can't guarantee that equally the PCH in the different sectors adopts identical running time-frequency resource, makes the soft merging mode of SFN to work too.
Therefore be necessary that the reception that designs other strengthens mode, to be implemented under the prerequisite that does not influence other data traffic transmission performances, improves the receptivity of paging information.

Embodiment
The present invention proposes the method for the soft merging of a kind of PCH, and has provided step and the equipment of realizing this soft merging receive mode.
At first the present invention has provided the PCH soft combination method that proposes in order to realize, the operating procedure that the base station is required, as shown in Figure 2:
At first base station configuration is transmitted the moment and the time interval of PI channel, the moment and the time interval of transmission PI channel, modulation coding mode (the Modulation Coding Scheme of transmission PI channel, MCS) and the channel Mapping of PCH, in addition, also to dispose the running time-frequency resource channel Mapping 201 of transmitting the channel of PI under the same base station in all sectors.Subscriber equipment need be known under the same base station that the base station disposes the running time-frequency resource channel Mapping of the channel of transmission PI in all sectors, the method of knowing can be to be fixed up by standard, also can be the channel of PI is transmitted in the base station in all sectors under the same base station in the broadcast channel in each sector under same base station running time-frequency resource channel Mapping information.Subscriber equipment has obtained after the above-mentioned information that the base station disposed, and just can know the running time-frequency resource position of other sectored transmissions PI channel under the same base station, just can receive under the same base station channel of transmission PI in each sector.
Afterwards, the base station channel Mapping running time-frequency resource that will use transmission PI channel indicated in the broadcast channel sends the PI information 202 of each sector.It should be noted that common base station can be in broadcast channel gives the resource of a plurality of transmission of each sector configuration PI, and in paging each time, the base station can use one or more resource to transmit PI.
Then, the base station channel Mapping running time-frequency resource that will use the indicated PCH of PI information that each sector sends sends the paging information 203 of each sector.
Afterwards, after the request of access at random that paged user sent has been received in the base station, can send response 204 to it.
It should be noted that the base station sends PI in each sector channel can be PICH independently, also can be the L1/L2 control channel.In addition, the channel Mapping running time-frequency resource of indicated PCH is different in the PI information that sends in each sector under the same base station.
Afterwards, provided the soft merging method of reseptance of PCH proposed by the invention subscriber equipment performing step as shown in Figure 3:
At first, the information 301 relevant that subscriber equipment will be known with paging, except knowing the moment and the time interval of transmission PI channel, modulation coding mode (the Modulation CodingScheme of transmission PI channel, MCS) and the channel Mapping information of PCH, outside, also to know the running time-frequency resource map information that transmits the channel of PI under the same base station in all sectors.That is to say that subscriber equipment will be informed in the shared running time-frequency resource of transmission PI channel in all sectors under the same base station.Subscriber equipment knows that the method for above-mentioned information can be by the standard above-mentioned information that is fixed up, or by broadcast channel broadcasts.
Secondly, subscriber equipment receives the channel of transmission PI in each sector under the same base station, that is to say according to the shared running time-frequency resource information of transmission PI channel in all sectors under indication cycle in 301 and the same base station, periodically receive the channel 302 of the transmission PI of all sectors under the same base station, detect paging group identifier and the running time-frequency resource map information that transmits PCH in each channel.The channel that it should be noted that transmission PI can be PICH independently, also can be the L1/L2 control channel.In addition, the running time-frequency resource of the transmission PCH that indicates in the PI information in each sector under the same base station is different.
Judge whether then correctly to have detected PI information 303, if do not detect then continue periodically to receive under the same base station channel 302 of transmission PI in all sectors; If detected, also to judge whether the group paged 304 at this user place, if there is not the paged channel 302 that transmits PI under the same base station in all sectors that continues so periodically to receive, if paged, to judge whether that also the channel of plural sectored transmissions PI is correctly received 305:
If, that is to say the channel that has detected in the plural sector transmission PI, 306 receive the indicated a plurality of PCH of corresponding a plurality of PI so with regard to mode with soft merging;
If not, that is to say the channel that has only detected transmission PI in the sector, 307 just with the indicated PCH of common mode (mode that does not have soft merging) the corresponding PI of reception so.
After receiving PCH, obtained information transmitted in the PCH, will judge this PCH whether paging be the identifier 308 of this subscriber equipment, if not, then continue periodically to receive under the same base station channel 302 of transmission PI in all sectors; If then 309 subscriber equipmenies will be initiated the initial request that inserts on Random Access Channel.
It should be noted that subscriber equipment when receiving the channel of transmission PI, receive the channel of the transmission PI that a plurality of sector sent same base station under, but the PCH that transmit the sector of having only the channel of the PI that those transmitted correctly to be received understands by soft merging.Therefore soft merging receive mode proposed by the invention is actually a kind of optionally soft merging mode.
Wherein, the performing step of the soft merging of a plurality of PCH is as shown in Figure 4 in the step 306:
At first subscriber equipment receives do radio frequency from the signal of antenna, mould/number conversion and go circulation prefix processing 401, secondly resulting signal is done fast Fourier transform (FFT) 402, and then each sector PCH channel Mapping information of indicating among the PI according to each sector transmission that receives is done the PCH channel 403 that channel Mapping obtains each sector to the signals of 402 outputs, afterwards each PCH channel is done the soft bit (Soft Bit) 404 that soft demodulation (Soft Demodulation) obtains each PCH channel, thereafter again with the soft bit addition 405 on each PCH channel, soft bit after just can being combined is at last done deinterleaving, separate chnnel coding 406, thereby finished the process of the soft merging of PCH.
The present invention gives the hardware of the required subscriber equipment of PCH soft combination method that realization proposes and realizes block diagram, as shown in Figure 5:
The channel Mapping information of these transmission PI channel will send the channel receiver 504 of the channel of transmission PI to, and this receiver will remove to receive the channel of each sectored transmissions PI under the same base station according to the channel Mapping information of each sectored transmissions PI channel.And the signal of the PI information that receives on each channel passed to PI information decoding device 505, the PI information on the transmission PI channel of a plurality of sectors that PI information decoding device can be decoded success again be passed to the channel Mapping information of PI information translater 506 with transmission PCH in these sectors that comprise in the identification PI information.
The channel Mapping information of the PCH of a plurality of sectors under the same base station of being identified will be passed to PCH receiver 507, the PCH receiver will be opened the Signal Separation of the last transmission of each PCH according to the channel Mapping information of each PCH, and they are made the soft bit signal that soft demodulation obtains the last transmission of each PCH respectively.Afterwards, the soft bit signal of the last transmission of each PCH is passed to adder 508 do soft merging, and the signal after will merging is passed to paging information decoder 509 and is decoded, decoded paging information signal will send to paging information translater 510 and identify paging information, and resulting paging information will be issued high level and carry out follow-up operation.
