Translated fromChineseDescription
Technical field
The present invention relates to wireless communication technology field, be specifically related to a kind of generation method, device of pilot frequency sequence.
background technology
The transmission of 3GPP LTE system descending can adopt subscriber equipment (UE) dedicated pilot signal (UE SpecificReference Signal) to carry out the data channel demodulation of wave beam complex (Beamforming) pattern.The downstream data channel that LTE strengthens (LTE-Advance) system all adopts UE dedicated pilot signal to carry out demodulation.
The detailed process that terminal is carried out data demodulates by pilot signal comprises: receive pilot signal, carry out transmission channel response and estimate, then according to the channel response estimating, detect the data-signal of transmitting terminal according to this pilot signal.
Wherein, according to this pilot signal, carrying out transmission channel response estimates to comprise, the pilot frequency sequence that the pilot signal that the known transmitting terminal of receiving terminal sends is carried, in this locality, generate the pilot frequency sequence of receiving terminal, receiving terminal receives the pilot signal after the transmission of space, according to the pilot signal receiving and known transmission pilot frequency sequence, know the channel response of the space transmission channel of pilot signal, because data-signal and pilot signal experience identical space transmission channel, therefore, also just obtain the transmission channel response of data-signal.
At cellular communication system, different districts adopts different pilot frequency sequences, to realize interference randomization between pilot signal, reduces the impact of presence of intercell interference.Pilot frequency sequence is generated by pseudorandom (PN) sequence conventionally, under identical shift register structure, and the different PN sequence of the corresponding generation of different Shift register initialization sequences.
LTE and LTE-Advance need to strengthen downlink throughput capacity, many UE spatial reuse is a kind of effective performance enhancement method, LTE strengthens downlink throughput capacity and adopts the mode that increases descending many UE beamforming, and the employing of LTE-Advance enhancing downlink throughput capacity strengthens design on many UE of LTE spatial reuse transmission mode basis.Many UE spatial reuse transmission mode specifically refers to, the data of different UEs are transmitted on identical running time-frequency resource by spatial reuse.But, under many UE spatial reuse transmission mode, because space channel can not guarantee complete quadrature, between multiplexing UE data together, can there is phase mutual interference.
