Description

A kind of launching technique of multiaerial system and device
Technical field
The present invention relates to the communications field, be specifically related to a kind of launching technique and device of multiaerial system.
Background technology
In radio communication, if all use many antennas at transmitting terminal and receiving terminal, can take the mode of spatial reuse to obtain higher speed, the different data of the i.e. emission of different antennae position on the identical running time-frequency resource of transmitting terminal, owing to can estimate each channel by channel estimating at receiving terminal, even therefore different data of each antenna emission after the signal matrix through MIMO (MIMO), still can solve emission data on each antenna at receiving terminal.
In the LTE system, in order to satisfy the demand of E-UTRA, the LTE system supports up using MIMO technique.The up basic antenna configurations of LTE is 1x2, i.e. a transmitting antenna and two reception antennas.In order to save power and to reduce the radio frequency expense, use the more power amplifier of peanut in the end side expectation.On the other hand, in order to improve accessible data rate and wider covering to be provided, the up day line options technology of having used of LTE, as shown in Figure 1.
The LTE uplink physical channel comprises Physical Random Access Channel (PRACH, Physical RandomAccess Channel), Physical Shared Channel (PUSCH, Physical uplink shared channel) and Physical Uplink Control Channel (PUCCH, Physical uplink control channel).The PUCCH channel format can be divided into two big classes, and totally 6 kinds: the first kind comprises 3 kinds of forms, i.e. format 1,1a, 1b, and second class comprises 3 kinds of forms, i.e. format 2,2a, 2b.First kind PUCCH is used to transmit SR (Scheduling Request, dispatch request) and ACK (Acknowledgement, confirm)/NACK (Negative Acknowledgement, non-affirmation) signaling, wherein, format 1 is used to transmit the ACK/NACK that ACK/NACK, format 1b that SR, format 1a be used to transmit single codeword stream are used to transmit two streams of code words.The second class PUCCH is mainly used in transmission CQI (Channel Quality Indicator, the channel quality indication), wherein 2 of format transmit CQI, format 2a is used for transmitting simultaneously the ACK/NACK of CQI and single codeword stream, and format 2b is used for transmitting simultaneously the ACK/NACK of CQI and two streams of code words.First kind PUCCH shared RB (Resource Block) in a time slot counts relevant with the quantity of down control channel unit (CCE, Control Channel Element), is dynamic change; The second class PUCCH shared RB number in a time slot is notified to all UE in the sub-district by broadcast channel, is semi-static preparation.In addition, for fear of the waste of sign indicating number resource, the LTE system has also defined mixing RB, the multiplexing first kind and the second class PUCCH channel.Whether exist mixing RB to prepare in the system, and in a time slot, have one to mix RB at most.In common sub-frame of uplink, PUCCH is positioned at the both sides of PUSCH frequency band, and the channel architecture of PUCCH as shown in Figure 2.
For different forms and different Cyclic Prefix (CP, Cyclic Prefix) length, the quantity and the residing position of reference signal (RS, the Reference Signal) symbol of PUCCH channel the inside can be different, as shown in Figure 3.
For the PUCCH channel, different user (UE, User Equipment) is undertaken multiplexing by the mode of sign indicating number branch (CDM) or frequency division (FDM).First kind PUCCH, available resource n_r is by three sub-resource representation (n_cs, n_oc, n_PRB), wherein n_cs represents the resource sequence number of cyclically shifted sequences (CS, circular shift), n_oc represents orthogonal code (OC, orthogonal covering) resource sequence number, the resource sequence number of n_PRB represents physical Resource Block (PRB, physical resource block).For example, when cyclic shift be spaced apart 1 the time, each symbol of Physical Resource Block the inside has 12 cyclically shifted sequences resources, and 3 orthogonal codes are arranged, so each PRB can a multiplexing 12x3=36 UE; When cyclic shift be spaced apart 2 the time, then each PRB can multiplexing (12/2) x3=18 UE.The second class PUCCH, (n_cs, n_PRB), orthogonal resource as shown in Figure 4 by two sub-resource representations for available resource n_r.
Evolve to the LTE-Advanced stage by LTE, in order to obtain higher transmission rate, the LTE-Advanced system supports the configuration of up 4 transmitting antennas.For the PUCCH channel,, come the emitter of appropriate design 4 antennas according to its format characteristic for backward compatibility LTE system and acquisition better transmission property.
