Description
Technical field
The present invention relates to the indication of wireless communication system link information interaction mode, relate in particular to Notification Method and the emitter thereof of the multi-access mode of wireless link information transmitting in the third generation mobile communication system (LTE/LTE-Advanced, IMT-Advanced).
Background technology
At OFDM (OFDM, Orthogonal Frequency Division Multiplexing) in system, by data flow being decomposed into several sub data flows, in the mode of OFDM, transmit, each sub data flow has lower transmission bit rate like this, then each sub data flow is modulated to respectively to the transmitting that walks abreast on corresponding subcarrier.It is pointed out that between each subcarrier of OFDM, be not only mutually orthogonal, and subcarrier mutually have 1/2 overlapping.
In LTE system, need take into full account peak-to-average power ratio (PAPR, the Peak Average Power Ratio of user terminal (UE, User Equipment) end, be called for short peak-to-average force ratio) problem, that is to say that the instantaneous value of the output signal of transmitter has larger fluctuation.This will require more intrasystem parts (such as power amplifier, A/D or D/A converter etc.) to have very large linear dynamic range.And conversely, the non-linear of these parts also can produce nonlinear distortion to the larger signal of dynamic range, the harmonic wave producing can cause the phase mutual interference of subchannel, thereby affects the performance of ofdm system.
In LTE system, uplink multi-address has finally been selected the multiplexing multiple access of single carrier frequency division (SC-FDMA, Single Carrier-Frequency Division Multiple Access) mode, and very important reason is for solving PAPR problem.Because the information symbol of single-carrier system is directly modulated to (or information symbol is done to some and be simply out of shape) in time domain, so its PAPR value is lower.Review multicarrier system, owing to there being at one time a plurality of carrier waves transmission information symbol simultaneously, and the information symbol of each carriers carry is separate, so PAPR value is larger, generally than the large 2～3dB of single-carrier system.High PAPR has increased the requirement to parts linear properties such as transmitter power amplifiers, this point is especially unfavorable to UT, so more satisfactory scheme of uplink multi-address is the Single Carrier Frequency Division Multiple Access mode that adopts band Cyclic Prefix (CP, CirclePrefix), i.e. SC-FDMA.
But system adopts the multi-access mode of SC-FDMA can make the performance of system be restricted.Development along with the third generation mobile communication system, because more and more accessing preferably, peak-to-average force ratio problem solves, therefore the uplink multi-address mode of terminal can be not limited to SC-FDMA, by other uplink multi-address mode, can guarantee the superperformance of terminal, the uplink multi-address mode that other can candidate for example has the multiplexing multiple access of single carrier frequency division (clustered SC-FDMA) mode of orthogonal frequency division multiplexing multiple access (OFDMA) mode, sub-clustering and N the multiplexing multiple access of single carrier frequency division (N * SC-FDMA) mode arranged side by side etc.Have, terminal is being carried out in link information reciprocal process with system again, and especially, in random access procedure, its peak-to-average force ratio may change, and for adapting to this variation, may need terminal conversion uplink multi-address mode, or needs base station conversion downlink multi-access mode.This with regard to need transmitting-receiving two-end can by this moment or next multi-access mode constantly adopting notify to opposite end.
In LTE system, there are two kinds of multi-form random access procedures, i.e. random access procedure and the random access procedure based on non-competing based on competition.Conventionally, the former is for the random access of the most terminals under the switching state of non-community, and latter is for the random access of the terminal under the switching state of community.
As shown in Figure 1, the random access procedure based on competition mainly comprises following four steps:
Step 1: terminal (UE) is by a random access guiding (Preamble code) of selecting at random, at Physical Random Access Channel (PRACH, Physical Random Access CHannel) on, be transmitted to base station (Node-B or eNode-B, this eNode-B is called for short eNB);
Step 2: accidental access response message, after the transmitting of Preamble code having been detected, is returned to terminal in base station;
In this accidental access response message that base station is returned, comprise following information: the numbering of the Preamble code of receiving, the time adjustment amount of the Preamble code correspondence of receiving, and be the indication information of the ascending resource position of this terminal distribution.
Step 3: terminal, after receiving this accidental access response message, according to the wherein indication of ascending resource position, is launched upstream message on the ascending resource of base station assigns;
The unique ID that at least comprises this terminal in this upstream message of terminal transmitting.
Step 4: base station receives after the upstream message of terminal, returns to competition to the successful terminal of access and solves message.
This competition that base station is returned solves in message and at least comprises the unique ID that accesses successful terminal.
As shown in Figure 2, the random access procedure based on non-competing mainly comprises following three steps:
Step 0: base station (Node-B or eNB) is assigned to terminal (UE) by special random access preamble assignment messages by special random access preamble at down direction;
Step 1: terminal is launched this random access guiding at up direction by PRACH;
Step 2: accidental access response message is above returned to terminal at DSCH Downlink Shared Channel (DL_SCH, DownLink_Share CHannel) in base station.
At present, for take ofdm system as the research of basic multi-access mode be a focus, but the Notification Method research of its multi-access mode of system of multiple multi-access mode is less for adopting, does not still form standard, complete way and make the transmitting-receiving two-end of base station or terminal can be on suitable opportunity by effectively, expense is known the multi-access mode that opposite end transmitting wireless link information adopts flexibly.
