Description
Technical field
The present invention relates to the mobile device signal receiving/transmission method in mobile communication system, particularly to the mobile device signal receiving/transmission method in a kind of time division synchronous-code division multiple access system.
Background technology
Along with Time Division-Synchronous Code Division Multiple Access (is called for short, TD-SCDMA) the deepening constantly of system evolved process, such as N frequency point networking, high-speed packet access and (are called for short, HSPA), multimedia broadcasting and multicast (is called for short, MBMS), high ferro (is called for short, HST) technology such as covering successively puts it over and application, effectively promotes the market manifestation of TD-SCDMA system.
But, N frequency point networking technology inevitably introduces comparatively prominent co-channel interference composition while promoting system spectrum utilization rate, improves Interference Signal Code Power (being called for short, the ISCP) grade of system. Described interference includes substantially tying down the handling capacity of HSPA business, controls the series performance of the transmitting-receiving success rate of channel, serious reduction user's impression.
In HST covering scene, for solving mobile equipment (being called for short, UE) frequently switching and gravity treatment problem, macrocell is generally adopted to cover, it is main stream approach that Base Band Unit (is called for short, BBU) strategy of arranging net of+remote antenna unit (being called for short, RRU). Described solution principle is that multiple RRU launches the signal from same BBU, and namely multiple RRU belong to same logic district, and its function is equivalent to many antennas of same base station. Obviously, in each RRU overlay area crossover position, receive signal resonance counteracting and/or Doppler frequency shift mutation effect is objective reality. The mechanism of production of Doppler's mutation effect is as follows:
Doppler frequency shift fdCalculating formula is:
Wherein, v is UE translational speed; �� is carrier wavelength; �� is UE moving direction and the angle receiving signal arrival bearing; When UE is in RRU marginal position, i.e. the aliasing overlay area of two RRU, UE moving direction receives signal angle �� with the RRU away from side1And receive signal angle �� with the RRU near side2Just supplementary angle each other in theory, therefore receives two RRU signals and carries Doppler frequency-shift opposite sign and absolute difference is aboutUE is for obtaining preferably receptivity, it is necessary in the aliasing overlay area of described two RRU, receives the instantaneous saltus step amount of signal Doppler frequency shift that is dominant and reachesThis is the Doppler frequency shift mutation effect under HST scene. Moving equipment translational speed, 2025MHz system operating frequency for 450km/h, the sudden change of described Doppler frequency shift may be up to 1.6875kHz. Additionally, aforementioned two RRU mentioned receive signal and carry Doppler frequency-shift opposite sign, it is also possible to causing that two with in frequency RRU edge scene, UE receives signal resonance and offsets, and brings distorted signals.
Existing mobile equipment generally uses the radio-frequency channel based on omnidirectional (to be called for short, passage, mean the antenna element possessing the predetermined coupling feature of predetermined radiation direction) signal transmit-receive method, in the face of the technological difficulties such as described co-channel interference, Doppler's saltus step, evaded essentially by the mode attempting introducing complicated software solution.
Resist for co-channel interference, existing software solution is to disturb elimination (abbreviation, IC) technology is representative, but, described scheme is owing to requiring that substantial amounts of fast Fourier transform (is called for short, FFT), channel estimating, the contour overhead operations of iterative repetition can obtain preferably effect, UE cannot be simultaneous for multiple business time-slot and process in real time, it is necessarily required to the IC effect of sacrificial section business time-slot, it is fatal that HSPA high speed downlink grouped is accessed high-speed data service impacts such as (being called for short, HSDPA) by described sacrifice.
Resist for Doppler frequency shift sudden change, the frequency deviation of main flow is estimated (to be called for short, FOE) with the FOE scheme that exports based on joint-detection equilibrium for representative, for supporting that the Doppler frequency shift of up to 1.6875kHz suddenlys change, the program is only capable of using the limited quantity symbol enforcement in close midamble territory in joint-detection equilibrium output to estimate, described symbol is except limited sample size is by except lifting estimate variance, the immediately balanced output symbol midamble smearing effects owing to being caused by wireless propagation environment of the data field 2 in midamble territory, the distortion of symbolic information can have a strong impact on FOE performance equally.
