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, different data are launched in the different antennae position on the identical running time-frequency resource of transmitting terminal, owing to can estimating each channel by channel estimating at receiving terminal, even if the therefore different data of each antenna transmission, after the signal matrix of MIMO (MIMO), still can solve the transmitting data on each antenna at receiving terminal.
In LTE system, in order to meet the demand of E-UTRA, LTE system is supported up using MIMO technique.The up basic antenna configuration of LTE is 1 × 2, i.e. a transmitting antenna and two reception antennas.In order to save power and to reduce radio frequency expense, expect to use the more power amplifier of peanut in end side.On the other hand, in order to improve accessible data rate and wider covering to be provided, the up Antenna Selection Technology that used of LTE, as shown in Figure 1.
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).PUCCH channel format can be divided into two large classes, and totally 6 kinds: the first kind comprises 3 kinds of forms, i.e. format 1,1a, 1b, Equations of The Second Kind comprises 3 kinds of forms, i.e. format 2,2a, 2b.First kind PUCCH is used for transmitting SR (Scheduling Request, dispatch request) and ACK (Acknowledgement, confirm)/NACK (Negative Acknowledgement, non-confirmation) signaling, wherein, format 1 for transmit SR, format 1a for the ACK/NACK, the format 1b that transmit single codeword stream for transmitting the ACK/NACK of two streams of code words.Equations of The Second Kind PUCCH is mainly used in transmitting CQI (Channel Quality Indicator, channel quality instruction), wherein 2 transmission CQI of format, format 2a is for transmit the ACK/NACK of CQI and single codeword stream simultaneously, and format 2b is for transmit the ACK/NACK of CQI and two streams of code words simultaneously.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; Equations of The Second Kind PUCCH shared RB number in a time slot notifies to all UE in community by broadcast channel, is semi-static preparation.In addition, for fear of the waste of code resource, LTE system has also defined mixing RB, the multiplexing first kind and Equations of The Second Kind PUCCH channel.In system, whether exist mixing RB to prepare, and in a time slot, have at most one to mix RB.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.
