Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment technical scheme done and further elaborate.
Embodiment 1
In order to solve, existing LTE system frequency resource utilization rate is low waits deficiency, present embodiments provides the method for adjustment of a kind of downlink reference signal, as it is shown in figure 1, the present embodiment method comprises the following steps:
Step S101: obtain terminal and receive the bit error rate of data；
After base station issues data to terminal, receiving the related data that terminal is sent, wherein just include terminal and receive the bit error rate of data, the bit error rate is to weigh the index of data data at the appointed time transmission accuracy.Generally, gross yards × 100% of the error code in the bit error rate=transmission/transmit, the bit error rate is relevant with the density of current base station and the downlink reference signal of terminal, also relevant with current network signal transmission environment.
Step S102: the bit error rate according to obtaining obtains down channel quality；
Here, the bit error rate can reflect that whether the density of the downlink reference signal of current base station and terminal is suitable, also can reflect the quality of current network signal transmission environment, therefore, directly related property according to the bit error rate and down channel quality, just can obtain down channel quality by the bit error rate；Specifically how to obtain down channel quality by the bit error rate belongs to prior art, repeats no more herein.
Step S103: the down channel quality obtained and setting threshold value are compared and obtain comparative result；
The percentage ratio that setting threshold value accounts for down channel quality ideally according to current downlink channel quality herein is arranged, for reflecting the quality condition of down channel, the threshold value pre-set includes two, one is set the channel quality higher limit that threshold value is corresponding, and one is set the channel quality lower limit that threshold value is corresponding；Wherein, channel quality higher limit is used for representing that current network signal transmission environment is fine, it is possible to reduce downlink reference signal density, such as: channel quality higher limit can be set to 80%；Correspondingly, channel quality lower limit represents that current network signal transmission environment is good not, in order to ensure data transmission quality, reduces the bit error rate, it is possible to increase downlink reference signal density, such as: channel quality higher limit can be set to 50%.
Concrete, described down channel quality and setting threshold value are compared, if the channel quality higher limit that described down channel quality is corresponding higher than described setting threshold value, then needs to reduce the density of downlink reference signal；During the described down channel quality channel quality lower limit corresponding lower than described setting threshold value, then need to improve the density of downlink reference signal；If described down channel quality is between channel quality higher limit corresponding to described setting threshold value and channel quality lower limit corresponding to described setting threshold value, that is: described down channel quality is corresponding not higher than described setting threshold value channel quality higher limit, also it is not less than the channel quality lower limit that described setting threshold value is corresponding, then need not adjust the density of downlink reference signal.
