Description

Method of mobile communication, Apparatus and system

Technical field

The present invention relates to the communications field, be specifically related to a kind of method of mobile communication, Apparatus and system.

Background technology

Multiple-input and multiple-output (Multiple-Input Multiple-Out-put, MIMO) technology is at Wireless Fidelity (wireless fidelity, WIFI), Long Term Evolution (long term evolution, etc. LTE) be widely applied in wireless communication technology, MIMO space multiplexing technique can by being divided into list entries multiplex data stream parallel transmission simultaneously, along with the increase of dual-mode antenna number, increase substantially channel capacity.Along with global system for mobile communications (Global System for Mobile Communications, global evolution (the Enhanced Data rates for Global Evolution of GSM)/enhanced data transmission, EDGE) wireless access network (GSM/EDGE Radio Access Network, GERAN) number of users in communication system increases and requirement to transfer of data speed increment fast, and 3GPP is studying and MIMO technology is being applied in GERAN technology.

Existing space multiplexing technique is sent by different channels respectively by different antennas by multiplex data stream, such as, as shown in Figure 1, in GERAN system, suppose that there is two-way antenna base station, and have two-way initial data stream to need to launch, first, sign map is carried out, corresponding generation two-way maps data streams X0 and X1 by after two-way initial data stream respectively modulating-coding; Then, by training sequence 2 (Training sequence code corresponding with every road antenna respectively for two-way maps data streams, and (Training sequence code TSC1), TSC2) carry out pulse (burst) according to consensus standard to map, carry out phase rotating afterwards, send to terminal at antenna 1 and antenna 2 finally by after pulse-shaping.Terminal is after receiving two paths of data stream by two-way antenna, report carrier/interface ratio (the Carrier-to-Interference Ratio of reflection two paths of data stream simultaneously, CIR), so that the modulation coding mode of corresponding initial data stream is determined, for the modulating-coding of armed initial data stream according to the carrier/interface ratio of every circuit-switched data stream in base station.

Therefore, terminal must support that the carrier/interface ratio of two paths of data stream reports simultaneously, and signaling is more, and feedback overhead is large, and due to the problem that GERAN feedback time is longer and presence of intercell interference causes carrier/interface ratio to fluctuate, base station is difficult to exactly according to carrier/interface ratio determination modulation coding mode; In addition, if initial data stream adopts identical modulation coding mode, base station is in order to ensure that the two paths of data stream sent can both be correctly decoded by terminal, and the modulation coding mode that base station must be determined according to lower carrier/interface ratio is encoded to initial data stream, thus causes the decline of throughput.

Embodiment

Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail.

Fig. 2 is the treatment state reference diagram of the method for mobile communication that the embodiment of the present invention provides, 0 to M-1 M antenna is altogether comprised in base station side, each antenna can both send downlink data to terminal under base station controls in MIMO subchannel, and described terminal is including but not limited to subscriber equipmenies such as mobile phones.Base station is when issuing data first, first according to the modulation coding mode of acquiescence, modulating-coding is carried out by needing the initial data stream sent, obtain modulated data stream, again by sign map, generate M road maps data streams X0 to X(M-1), after afterwards Homogeneous phase mixing being carried out to M road maps data streams, generate M road blended data stream C0 to C(M-1), launched by different antennas.Particularly, every road blended data stream can be different according to transmitting antenna, in conjunction with different training sequence TSC (0) to TSC(M-1), to each road blended data stream in conjunction with respective training sequence, after carrying out pulse map and phase rotating respectively, carry out pulse-shaping, then send to terminal from the antenna of correspondence.

As shown in Figure 3, based on above-mentioned core concept, embodiments provide a kind of method of mobile communication, described method comprises:

301, according to modulation coding mode, modulating-coding is carried out to M road initial data stream, obtains M road modulated data stream, this M be greater than 1 positive integer, and M is not more than the number of antenna.

Wherein, initial data stream refers to the data flow before modulating-coding, can be bit data flow, give restriction herein; Identical modulation coding mode is adopted to carry out modulating-coding respectively to M road initial data stream.

It is to be noted, base station is when sending initial data stream first, the modulation coding mode pre-set can be adopted to carry out modulating-coding to M road initial data stream, and this modulation coding mode pre-set can be set in advance in inside of base station, is also configured by input equipment.

302, respectively sign map is carried out to M road modulated data stream, generates M road maps data streams.

303, M road maps data streams is mixed, generates M road blended data stream.

Specifically, base station mixes the maps data streams after sign map, and the symbol in the maps data streams of M road is mixed in blended data stream as far as possible equably, thus the symbol in different maps data streams can be sent on different antennas.

304, M road blended data stream is sent to terminal respectively on different antennas.

In step 304, M road blended data stream, flowing to horizontal pulse mapping, phase rotating and pulse-shaping process to M road blended data before different antennas sends to terminal, belongs to prior art, repeats no more herein.

305, receiving terminal obtains according to the carrier/interface ratio of described M road blended data stream and the carrier/interface ratio of the road maps data streams fed back.

Specifically, terminal according to the data received to base station feedback measurement report, can comprise carrier/interface ratio in this measurement report, the useful signal intensity namely on channel and the ratio of interference signal intensity after the data receiving base station transmission.In step 303, transmission blended data stream is launched by different antennae in base station, the carrier/interface ratio difference of every road blended data stream that terminal is received is larger, but because blended data stream mixes multichannel maps data streams, make terminal after the symbol in the blended data stream of every road is reduced into unmixing maps data streams, the carrier/interface ratio of the every road maps data streams obtained is substantially identical, therefore terminal only needs the carrier/interface ratio uploading a road maps data streams can react the carrier/interface ratio of whole maps data streams, determines modulation coding mode for base station.

It should be understood that terminal obtains the mode of the carrier/interface ratio of a road maps data streams, can have multiple choices, such as, the carrier/interface ratio of M road blended data stream is averaged by terminal, and this mean value is as the carrier/interface ratio of a road maps data streams; Terminal also can carry out solution mixing to the M road blended data stream received, blended data stream is reverted to the M road maps data streams before not having to mix, calculate the carrier/interface ratio of a wherein road maps data streams again, this road can be any road in the maps data streams of M road; Select the maximum or minimum CIR of a road CIR to report base station in the M road maps data streams that terminal can also obtain after separating mixing, will not limit herein.

306, according to the described carrier/interface ratio determination modulation coding mode of a described road maps data streams.

Concrete, base station is after the carrier/interface ratio receiving terminal feedback, and for different carrier/interface ratio determination modulation coding modes, this modulation coding mode is used for the modulating-coding next time needing the initial data stream of launching, such as carrier/interface ratio is poor, then select the coded system that code check is less.

Pass through the above embodiments, after maps data streams after sign map is blended in blended data stream by base station as far as possible equably, different antennas sends to terminal respectively, such terminal is through mixed blended data stream by the data that different antennae receives, after symbol in blended data stream is reverted to maps data streams, the carrier/interface ratio of each maps data streams is substantially identical, therefore terminal only needs the carrier/interface ratio reporting a road maps data streams, select the modulation coding mode of follow-up initial data stream according to the carrier/interface ratio of a road maps data streams of terminal to report for base station, decrease feedback information volume, simultaneously, multiple initial data stream adopts identical modulation coding mode, higher throughput can be obtained.

Below in step 303, base station is described several embodiments that maps data streams mixes.

The symbol of M road maps data streams, in units of single symbol, mixes by mode one, base station, obtains M road blended data stream.

Such as, as M=2, exchange every the symbol of a symbol to two-way maps data streams same position, obtain two-way blended data stream.

For maps data streams X0 and maps data streams X1, suppose that the symbol numbers of a road maps data streams in a pulse (burst) is N, the symbol of X0 in a pulse is [X0 (0), X0 (1), X0 (N-1)], the symbol of X1 in a pulse is [X1 (0), X1 (1), X1 (N-1)], so exchange every the symbol of a symbol to maps data streams X0 and X1 same position, mixed two-way blended data stream C0 and C1 can be obtained and be respectively:

C0=[X0(0),X1(1),X0(2),X1(3),…,X0(N-2),X1(N-1)]

C1=[X1(0),X0(1),X1(2),X0(3),…,X1(N-2),X0(N-1)]

In Fig. 4, the CIR of the CIR of 2 tunnel maps data streams and 2 tunnel blended data streams is compared, wherein, MIMO subchannel 0 respective antenna 0, MIMO subchannel 1 respective antenna 1.Left side is not for carrying out the carrier/interface ratio of the maps data streams mixed, right side is the carrier/interface ratio according to the mixed blended data stream of above-described embodiment, the CIR of 2 tunnel maps data streams of visible prior art is different, but through being after unit mixes with symbol, for symbol in maps data streams X0, such as X0 (0) and X0 (1) are although intersymbol CIR is widely different, and the CIR of maps data streams X0 and X1 is similar to identical as a whole.Therefore, terminal only needs the CIR to base station feedback one tunnel maps data streams can react the carrier/interface ratio of whole maps data streams, thus saves feedback overhead.
