Description
Technical field
The present invention relates to wireless communication field, more particularly to a kind of is the method and apparatus of terminal distribution down channel.
Background technology
With the development of the communication technology, LTE system has turned into the trend of future network development.In the prior art, to LTE
The power distribution mode of the downlink of eNodeB base stations takes constant power distribution mechanism in system, i.e., for PDSCH
（Physical Dowlink Shared Channel, Physical Downlink Shared Channel）In each RB resource allocation identical work(
Rate value.As shown in figure 1, being the power distribution schematic diagram of the downlink of eNodeB base stations in existing LTE system, it is assumed that for
It is 20W that eNodeB base stations can be used power resource, 100 RB resources is had in the downlink, then use constant power
Distribution mechanism, the performance number that each RB resource is obtained is 200mW.
Because LTE system uses AMC（Adaptive Modulation and Coding, Adaptive Modulation and Coding）
Technology, the transmission power in the ability for possessing fast dispatch, with 3G systems to downlink channel carries out fast power control not
Together, downlink traffic channel is adopted as the mode of each channel resource allocation identical transmission power in LTE system, mainly passes through
AMC technologies and dispatching technique carry out channel circumstance adaptation, but this mode is not particularly suited for any LTE deployment scenarios, reason
It is as follows：
In typical in-door covering scene, carried out by the simulation result and test data of eNodeB downlinks
Analysis is it is recognised that as the SINR of user terminal（Signal to Inferterence plus NoiseRatio, signal to noise ratio）
When reaching 22.2dB, LTE system PDSCH will be using highest MCS grades, when making user's end by way of increasing transmission power
When the SINR at end is more than 22.2dB, LTE system still uses highest MCS grades, and user rate is no longer lifted, in such case
Under, increase transmission power for terminal service rate lifting will without in all senses, causing the waste of power resource on the contrary, and
The user relatively low for SINR, lifting transmission power can be obviously improved MCS grades, so as to bring substantially carrying for user rate
Rise.Therefore the existing mode for each channel resource allocation identical transmission power is not optimal power allocation scheme.
As shown in table 1, be in certain region LTE indoor covering systems covering under RSRP（ReferenceSignal
Receiving Power, Reference Signal Received Power）With the distribution table of the SINR of user terminal：
Table 1
As shown in Table 1, under various different scenes, by LTE indoor covering systems（RSRP>=-105dBm）Surveyed
Amount, it is found that the probability that the SINR of user terminal is distributed between 18.77dB ~ 29.16dB reaches 50%, i.e., in LTE in-door coverings
Under scape, the SINR that user terminal obtains signal in 50% region can exceed 18.77dB, the original constant power distribution of LTE system
Mode will cause the waste of power resource.
Therefore, can only use the mode of firm power that transmission power is distributed for downlink in existing LTE system, but
This mode will cause the transmission power of the preferable user terminal distribution of channel to exceed the transmission power of itself needs, Huo Zhexin
The need for the transmission power of the poor user terminal distribution in road can not meet itself, so, cause LTE system in the prior art
After carrying out power distribution, there is the relatively low problem of transmission power resource utilization.
The content of the invention
The method and apparatus that a kind of transmission power to down channel is adjusted is the embodiment of the invention provides, for solving
After certainly LTE system carries out constant power distribution in the prior art, the problem for causing transmission power resource utilization relatively low.

Network side is according to being terminal distribution suitable down channel the need for terminal, it is to avoid be terminal point present in prior art
The too high waste for causing of the transmission power of the down channel matched somebody with somebody, targetedly for the suitable down channel of terminal distribution improves
The utilization rate of down channel transmission power, meets different demands of the multiple users to network.
Each embodiment of the invention is described in detail with reference to Figure of description.
As shown in Fig. 2 being a kind of flow chart of method for terminal distribution down channel of the invention, methods described bag
Include：
Step 101：The signal to noise ratio SINR information that receiving terminal is reported.
In a step 101, when the signal to noise ratio SINR information of terminal to report is received, network side can perform industry to terminal
Be engaged in need channel power judged, further determine terminal need downlink transmission power.
More preferably, network side performed following operation before the signal to noise ratio SINR information for receiving terminal to report：
First, the transmission power of the down channel of each SINR information needs is calculated.
Specifically, due in LTE system, when terminal it is affected by noise different, it is necessary to down channel transmitting
Power is different, that is, the SINR information for gathering it is different, it is necessary to down channel transmission power it is different, wherein：SINR information numerical value
It is bigger, it is necessary to down channel transmission power it is lower.
Secondly, the corresponding relation set up between the transmission power of SINR information and the down channel being calculated.
Specifically, the corresponding relation between SINR information and the transmission power of down channel is locally stored in network side, such as
Shown in table 2：
| Transmission power | SINR information |
| 50mW | Not less than 28dB |
| 200mW | 18dB~28dB |
| 355mW | No more than 18dB |
Table 2
This ensure that the real-time of frequency domain resource scheduling, has broken the principle distributed according to constant power, it is more suitable for network
The development of system, improves the utilization rate of Internet resources.
More preferably, network side performed following operation before the signal to noise ratio SINR information for receiving terminal to report：
First, multiple down channels are divided into different groups by the quantity of the transmission power according to the down channel being calculated,
Wherein, the transmission power of down channel is identical in each group and be that each component matches somebody with somebody an identification information.
Specifically, the quantity of the transmission power that statistics determines according to SINR information, according to the quantity of statistics by one
The down channel of eNodeB base stations is divided, wherein, the transmission power of down channel is identical in each group and be each component
With an identification information, at least one down channel is contained in each group.
It should be noted that the down channel of base station can be divided into the quantity by the quantity according to statistics
Group.
For example：The transmission power of determination is 50mW, 200mW and 355mW, that is, have 3 different transmission powers, one
The quantity of eNodeB base station down channels is 99, according to homeostatic principle, an eNodeB base station down channel is divided into 3 groups, often
The quantity of the down channel included in a group is 33, then for the identification information that first group of down channel determines is to meet 3K；It is
The identification informations of two groups of down channel determinations are to meet 3K+1；For the identification information that the 3rd group of down channel determines meets 3K+2,
Wherein, K is 0 ~ 32 positive integer.

Transmission power adjusting module, for the probable value and noise that are occurred according to each the history signal to noise ratio SINR information for determining
Than the corresponding relation between SINR information, it is determined that the corresponding probability of signal to noise ratio SINR information of the terminal to report for receiving
Value, and the transmission power that will be calculated of probable value using the determination is adjusted, and obtains the corresponding tune of the SINR information
Transmission power after whole；
First sets up module, is additionally operable to set up the corresponding pass between SINR information and the transmission power of the down channel after adjustment
System.
