Wherein,

Concrete value see 36.104 agreements for details.

Above-mentioned ρ _BAnd ρ _ADefinite method that parameter is concrete can adopt prior art.

If

Then according to value and the ρ of CRS EPRE _B, ρ _AValue, definite PDSCH EPRE power sends data.

Wherein, the value of CRS EPRE is pre-configured default value.

If

Then can select to take one of following four kinds of schemes to handle, specifically describe as follows:

Scheme one:

Suppose β=calculating gross power/gross power, namely

So:

Base station side: the transmitting power of each RE of PDSCH is (ρ _AP _CRS)/β, P _CRSBe the transmitting power of each residential quarter dedicated reference symbols, namely the transmitting power of each RE has been reduced β doubly, because the EPRE of CRS is constant, so the EPRE ratio of the EPRE of PDSCH and CRS changes.

The UE side: know the transmitting power of each RE of PDSCH and the transmitting power of CRS according to higher level parameters, wherein, the transmitting power of each RE of PDSCH is ρ _AP _CRS, and the EPRE of CRS is constant, so the EPRE ratio of the EPRE of PDSCH and CRS is constant.

Scheme two:

Suppose β=calculating gross power/gross power, namely So,

Base station side: the transmitting power of each RE of PDSCH is (ρ _AP _CRS)/β, the transmitting power of CRS is P _CRS/ β, so, the EPRE ratio of the EPRE of PDSCH and CRS is constant.

The UE side: know the transmitting power of each RE of PDSCH and the transmitting power of CRS according to higher level parameters, wherein, the transmitting power of each RE of PDSCH is ρ _AP _CRS, and the EPRE of CRS is constant, so the EPRE ratio of the EPRE of PDSCH and CRS is constant.

Scheme three:

Determine the resource distribution failure of the certain customers of current successful Resources allocation.

Scheme four:

The current dispatched users for the treatment of is carried out resource again and distributed.

Scheme four for carry out before each user resource allocation can Resources allocation judgement, when distributing the PRB resource namely in subframe each user, consider to remain the limiting factor that available horsepower can be supported the PRB number, guarantee that the transmitting power of each OFDM symbol can not surpass maximum transmission power.Concrete steps are as described below:

Step 1: utilize following formula statistics successful Resources allocation user's gross power P _Allocated

$P_{\mathrm{allocated}}=\underset{i=0}{\overset{N}{\mathrm{\Σ}}}{P}_{{\mathrm{ue}}_i}$

Wherein, N is the number of users of successful Resources allocation,

Be i the shared power of successful Resources allocation user, be shown below:

$P_{{\mathrm{ue}}_i}=12\·{\mathrm{\ρ}}_{A\_{\mathrm{ue}}_i}\·P_{\mathrm{CRS}}\·N_{{\mathrm{ue}}_i}^{\mathrm{PRB}}$

Wherein,

It is the PRB number that i user becomes the distribution of work.

Step 2: determine to remain the maximum resource number that available horsepower can be distributed to user j.

Suppose that the next dispatched users of determining is ue _j, so, according to residue available horsepower P _AvailableAnd ue _jThe performance number of each PRB, determine to distribute to ue _jAvailable PRB number N _{Power_available}

Remaining available horsepower is:

$P_{\mathrm{available}}=P_{\max }^{\left(p\right)}-P_{\mathrm{allocated}}$

Ue _jThe performance number of each PRB is shown below:

$P_{{\mathrm{ue}}_j}^{\mathrm{PRB}}=12\·{\mathrm{\ρ}}_{A\_{\mathrm{ue}}_j}{P}_{\mathrm{CRS}}$

Ue _jAvailable PRB number is at most:

$N_{\mathrm{power}\_\mathrm{available}}=P_{\mathrm{available}}/P_{{\mathrm{ue}}_j}^{\mathrm{PRB}}$

Step 3: determine the PRB number that the user distributes.

According to ue _jAvailable PRB number N _{Power_available}Restriction, be ue _jDetermine that the PRB number that finally can distribute is N _{Power_available}

The pluses and minuses of above-mentioned four kinds of schemes are as follows respectively:

The pluses and minuses of scheme one: scheme is simple, but because the UE side thinks that the EPRE ratio of the EPRE of PDSCH and CRS is constant, and the EPRE ratio of the EPRE of base station side PDSCH and CRS has changed, so, the situation that this scheme can cause UE side and base station to understand differently and cause occurs, and influences the data demodulates of UE side.

The pluses and minuses of scheme two: scheme is simple, and the UE side thinks that the EPRE ratio of the EPRE of PDSCH and CRS is constant, understands with base station side to be consistent, so can not influence data demodulates.But because the UE side thinks that the transmitting power of CRS is P _CRS, and the transmitting power of base station side CRS is P _CRS/ β is so the situation that has caused UE side and base station side to understand differently and cause can influence channel estimating.

The pluses and minuses of scheme three: scheme is simple, but because the descending scheduling module has been given user's success Resources allocation, but because the restriction of power can not be dispatched this user, so, may cause quality of services for users (QoS) to be guaranteed, system resource can not fully be used.

The pluses and minuses of scheme four: because the descending scheduling module has successfully been distributed resource for dispatched users, because the restriction of power need be carried out resource again and distribute, increased the complexity of scheduling.But because this scheme does not influence data demodulates, channel estimating, and user's qos requirement, and system resource is fully used, and therefore, consider to reduce under the situation of complexity as far as possible, realize the power protection.
