A most important evolution tendency of the MIMO technology during Standardization Development is the extension of dimension.In LTE In Rel-8 (LTE8 ranks), 4 layers of MIMO transmission can be at most supported.Rel-9 (LTE9 ranks) emphasis is to MU-MIMO (Multi- User MIMO, multi-user's multiple-input, multiple-output) technology strengthened, TM (Transmission Mode, transmission mode) -8 MU- 4 downlink data layers can be at most supported in MIMO transmission.Rel-10 (10 rank), which is then introduced, supports 8 antenna ports further to improve The spatial resolution of channel condition information, and further by SU-MIMO (Single-User MIMO, single user multiple-input, multiple-output) Transmittability extend to most 8 data Layers.Rel-13 (13 rank) and Rel-14 (14 rank) introduce FD-MIMO (Full Dimension MIMO, full dimension multiple-input, multiple-output) technical support to 32 ports, realizes that the wave beam of full dimension and vertical direction is assigned Shape.
In order to further lift MIMO technology, extensive antenna technology is introduced in GSM.For base station, totally The extensive antenna of word can have up to 128/256/512 antenna oscillator, and up to 128/256/512 transmitting-receiving letter Machine, each antenna oscillator connect a transceiver.The pilot signal of 128/256/512 antenna port is up to by sending, So that terminal measure channel state information and feeding back.For terminal, the antenna array of 32/64 antenna oscillator can also be configured up to Row.By the wave beam forming of base station and terminal both sides, huge beam forming gain is obtained, to make up the letter that path loss is brought Number decay.Especially communicated in high band, such as on 30GHz frequencies, path loss causes the coverage of wireless signal extremely It is limited.By extensive antenna technology, the coverage of wireless signal can be expanded to can be practical scope in.
But in the normalized version of GSM, being all to support full digital antenna array at present, i.e., it is each Antenna oscillator has independent transceiver, it will so that the size of equipment, cost and power consumption significantly rise.Especially for The analog-digital converter (ADC) and digital analog converter (DAC) of transceiver, nearly ten years, its power consumption only reduces 1/10 or so, property It can be lifted also than relatively limited.In order to reduce the size of equipment, cost and power consumption, the technical scheme based on analog beam figuration is carried Go out, as depicted in figs. 1 and 2.Analog beam figuration is mainly characterized by by phase shifter to intermediate frequency (Fig. 1) or radiofrequency signal (figure 2) it is weighted figuration.Advantage is that all transmitting (reception) antennas only have a transceiver, realizes simply, reduces into Originally, size and power consumption.
In order to further lift simulation wave beam forming performance, a kind of digital analog mixed wave beam forming transmit-receive structure scheme quilt It is proposed, as shown in Figure 3.In figure 3, transmitting terminal and receiving terminal have respectivelyWithIndividual transceiver, transmitting terminal antenna oscillator NumberReceiving terminal antenna oscillator numberWave beam forming support maximum parallel transmission stream quantity beFig. 3 mixed-beam figuration structure is in digital beam forming flexibility and the low complex degree of analog beam figuration Between balance, there is the ability for supporting multiple data flows and multiple users figuration simultaneously, meanwhile, complexity is also controlled reasonable In the range of.
However, because analog beam figuration or numerical model analysis wave beam forming are firstly the need of hair in following extensive antenna system Sending end and the correct transceiving data of receiving terminal alignment beam direction ability, so need to carry out terminal reception wave beam training, and it is traditional Do not needed in system, the scheme of wave beam training is also received in the absence of terminal.
