Embodiment
Embodiments provide sending, receiving method and the relevant apparatus of the control signal that a kind of E-TFC selects, for improving the feedback accuracy of SR and solving the problem of base station to subscriber equipment feedback IO.
For making goal of the invention of the present invention, feature, advantage can be more obvious and understandable, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, the embodiments described below are only the present invention's part embodiments, and not all embodiments.Based on the embodiment in the present invention, the every other embodiment that those skilled in the art obtains, all belongs to the scope of protection of the invention.
The sending method of the control signal that a kind of E-TFC that the embodiment of the present invention provides selects, as shown in Figure 2, comprising:
201, base station obtains the control signal that E-TFC selects, and wherein, control signal comprises: double-current channel quality ratio (SR, Signal to Noise Ratio Ratio) and/or interference biased (IO, InterferenceOffset).
In embodiments of the present invention, the control signal that base station obtains E-TFC selection can comprise following three kinds of modes: base station obtains SR, and base station obtains IO, and base station obtains SR and IO, and the control signal that is base station obtains at least comprises the one of SR and IO.
In UL-MIMO, because main flow is different with the characteristic of channel of secondary flow process, need to use different parameter scheduling.Base station uses the channel quality of inner-loop power control adjustment main flow, on this basis, double-current channel quality can be used to select than for the E-TFC realized for secondary flow, base station obtains double-current channel quality ratio, concrete, above-mentioned double-current channel quality ratio can be estimated in the following way and obtains: base station is according to one of the optimum chosen group of orthogonal precoding and the uplink channel estimation that obtains according to the major-minor pilot tone that UE reports, and according to the double-current transmitting power that absolute grant value is estimated, the Signal to Interference plus Noise Ratio (SINR) of (such as after equilibrium treatment) after drawing the process in main flow and secondary flow, suppose that the Signal to Interference plus Noise Ratio after main flow process is SINR1, Signal to Interference plus Noise Ratio after secondary flow process is SINR2, then double-current channel quality ratio SR can get with following formula: SR=SINR2/SINR1.And adopt the hypothesis of equal transmit power based on UE side mainstream data channel E-DPDCH and secondary flow data channel S-E-DPDCH when double fluid, the main flow scheduling authorization value SGp that UE can issue according to base station and SR calculates the equivalent scheduling authorization value SGs in secondary flow, thus realizes selecting to adjust to the E-TFC of secondary flow.Such as, calculate according to formula S Gs=SR*SGp, wherein, the scheduling authorization value of secondary flow that what SGs represented is.Decibel (dB) form that SR also can be defined as SINR2/SINR1 ratio or the side-play amount be defined as in SGp quantification form, at this moment computing formula is specially SGs=SGp-SR.Certainly, the embodiment of the present invention also can be obtained by other evaluation method and representation and issue the channel quality ratio information of above-mentioned double fluid, such as, reception Signal to Interference plus Noise Ratio before base station can directly use equilibrium treatment in major-minor pilot tone, to estimate double-current channel quality ratio, adopts main flow E-TFCI to be biased and represents; Or, double fluid channel quality ratio can be the transmission power offset amount of secondary flow relative to main flow, and secondary flow and main flow adopt equal-wattage transmission data, but when E-TFC selects, secondary flow should deduct this power offset on main flow through-put power basis, to adjust transmission block size.Concrete restriction is not done to the representation of double-current channel quality ratio herein.
In UL MIMO, two data flow in double fluid use identical code channel set, disturb so can produce between stream, and do not exist between stream under single stream case and disturb.Therefore when the main flow in single current and double fluid adopt identical transmitting power, experience identical channel and receiver end noise identical when, in double fluid, the Signal to Interference plus Noise Ratio of main flow is less than the Signal to Interference plus Noise Ratio of single current.Disturb to tackle between stream, base station need to UE to issue between stream E-TFC that interference biased IO, UE carry out main flow under double-stream mode select time, disturb the difference in channel quality of generation between the stream needing to consider that base station side issues.Between above-mentioned stream, interference can be estimated in the following way and obtains: base station is according to one of the optimum chosen group of orthogonal precoding and the uplink channel estimation of major-minor pilot tone acquisition that reports according to UE, and according to the transmitting power P1 of main flow on the double fluid that absolute grant value is estimated, the Signal to Interference plus Noise Ratio (SINR) of (after equilibrium treatment) after drawing main flow process, suppose that the Signal to Interference plus Noise Ratio after main flow process is SINR1, when base station estimation simultaneously adopts power P 1 to carry out single current transmitting, the Signal to Interference plus Noise Ratio SINRs of (after equilibrium treatment) after the single current process obtained, then IO can be defined as SINR1/SINRs or its dB form.Certainly, it is biased that the embodiment of the present invention also can obtain interference between above-mentioned stream by other evaluation method, such as, base station can be that user device configuration many groups is gathered with reference to E-TFC, and equipment for indicating user uses a certain group of reference E-TFC set to select for E-TFC as disturbing between stream to be biased when stream transmission; Or, main flow that between stream, interference is biased when can also be stream transmission is used for scheduling authorization value that E-TFC selects relative to relative to the side-play amount of scheduling authorization value being used for E-TFC selection during single-stream transmission, main flow is when E-TFC selects, the basis of the scheduling authorization value that should issue in base station deducts this power offset, to adjust transmission block size.Be not construed as limiting herein.
202, at least 6 symbols of control signal by least two continuous print subframes of destination channel feed back to subscriber equipment by base station, wherein, control signal at least takies 6 bits altogether, if control signal comprises SR, then SR at least takies 4 bits, and the spreading factor of destination channel is 256, and 1 system-frame of destination channel comprises 5 subframes, each subframe comprises 3 time slots, and each time slot comprises 10 symbols.
In inventive embodiments, the base station destination channel taken that sends control signaling meets following feature: 1 system-frame of destination channel includes 5 subframes, each system-frame is the length of 10ms, each subframe includes 3 time slots, each time slot includes 10 symbols, and the spreading factor (SF, Spreading Factor) of destination channel is 256, that is, the number of chips that 1 symbol of destination channel that the embodiment of the present invention provides comprises after spreading is 256.
