Technical field
The present invention relates to the mobile communication technology field, relate in particular to power compensating method and device in a kind of speech business.
Background technology
In the speech business in the prior art, can transmit corresponding speech data and relevant signaling by code channel.Therefore, in the same speech frame in speech business, may only carry speech data (being Frame), also may when carrying speech data, also carry relevant signaling (being the data signaling frame).
In existing speech business technology, the appearance of data signaling frame will cause corresponding channel-decoding gain to worsen.For example, using convolution code (CC) to carry out channel coding/decoding, and when 2 virtual resource units (VRU) had only speech data to transmit, the value of the transformat combination of this moment indication (TFCI) was 22, namely represents only to be Frame by the code channel transmission.At this moment, if use adaptive multi-rate (AMR) technology, then therefore bit (bit) number of the audio data stream behind the coding total bit number that will can carry greater than 2 VRU, need remove about data flow of about 15%.At this moment, mode that generally can be by inner-loop power control compensates the coding gain of above-mentioned channel, thereby improves the accuracy of transfer of data.
Yet, when same use convolution code (CC) is carried out channel coding/decoding, if what transmit on 2 VRU is the data signaling frame that carries signaling, the value of the TFCI of this moment is 23, and the bit number of resulting data flow will be far longer than total bit number that 2 VRU can carry after using the AMR technology to encode.In the case, may need to remove about data flow of about 36%.So, for the situation of only transmitting Frame, when there is the data signaling frame in the up direction in speech business, will cause tangible channel-decoding gain to worsen, and this channel-decoding gain deterioration is difficult to compensate by the mode of inner-loop power control.
Therefore, in current 3G system, when there is the data signaling frame in the up direction in speech business, network side will at first be preset a power factor correspondence table, and this power factor correspondence table is used for being recorded in the power factor that adopts under the different TFC situations; Then, network side is notified UE in the signaling that business is set up, require UE according to the situation of the TFC of reality and above-mentioned power factor correspondence table, determines employed power factor, thereby above-mentioned channel-decoding gain deterioration is compensated.
In the prior art, above-mentioned processing method has apparent in view compensating action for the less scene of signaling bag in the up data signaling frame.Its reason is that UE will select corresponding power factor according to the power factor correspondence table, thereby the direct corresponding transmitting power of lifting improves the value of the signal to noise ratio (snr) of base station (NodeB) when side is decoded.
Yet, for the up signaling frame that greatly needs a plurality of radio frames to send owing to the signaling bag to finish, if use above-mentioned power compensating method, then only can be in a radio frames the corresponding transmitting power of lifting, in follow-up radio frames, will thereby reduce corresponding transmitting power again owing to the former of inner-loop power control, thereby make and in follow-up radio frames, can't carry out above-mentioned power back-off again, thereby will cause the lasting deterioration of channel-decoding gain.When the important long letter of transmission makes, cause signaling decoding to continue the high-rise flow process failure that failure causes easily.Simultaneously, under this scene, the decoding efficiency of Frame also will worsen, thereby causes the decline of user's perception.
