In first stage, channel estimating is carried out to the common down channel of signal transmission in the terminal, confirms to characterize PMI (Precoding Matrix Index, the pre-coding matrix index) message of current channel characteristics, and is carried at and sends to the base station in the measurement report.
Wherein, Said PMI message is the signal quality of the base station side antenna that measures according to self of terminal; Select pre-coding matrix; And give the base station as the PMI information reporting with its index, the base station utilizes the corresponding pre-coding matrix of pre-coding matrix index that receives to carry out precoding to sending signal, reaches the purpose of the antenna of selecting to communicate between base station and the terminal.

Compared with prior art; In the report stage of communication; Consider the situation of the suffered interference in terminal, and, be the channel that the new PMI of terminal distribution confirms according to the order of severity of suffered interference; Avoid base station and the terminal bigger problem of suffered interference when communicating, improved base station and communication between terminals quality.
Below in conjunction with Figure of description various embodiments of the present invention are described in detail.
Embodiment one:
As shown in Figure 1, be the flow chart of a kind of method for communicating of present embodiment one, this method comprises:
Step 101: PMI that receiving terminal reports and interference parameter.
Wherein, the said PMI that receives is that the terminal is measured definite according to pilot signal to down channel.
In step 101, the terminal is measured the interfere information at terminal between self suffered Serving cell and neighbor cell, and confirms self suffered disturbed condition, offers the base station with interference parameter in form.
Simultaneously, the terminal is measured common down channel according to the pilot signal that the base station issues, and combines the Processing Algorithm of self storage, and the result after handling is reported the base station as PMI.
Number of data layers that lower floor's link can support and index information of pre-coding matrix etc. have been comprised among the said PMI.
Step 102: according to the corresponding relation between PMI and the interference threshold, whether judge the said interference parameter that receives greater than the corresponding interference threshold of the PMI that receives, if not, then execution in step 103; Otherwise execution in step 104.
In step 102, the corresponding relation between PMI and the interference threshold can be stored in the base station in advance, also can store the corresponding relation between PMI and the interference level in the base station, and the corresponding relation between interference level and the interference threshold.
Particularly, whether judge the said interference parameter that receives greater than the corresponding interference threshold of the PMI that receives, said method comprises:
The first step:, confirm the corresponding interference threshold of PMI that receives according to the corresponding relation between PMI and the interference threshold;
Particularly, if store the corresponding relation between PMI and the interference level, and the corresponding relation between interference level and the interference threshold, then confirm the corresponding suffered interference level in terminal of PMI that receives according to PMI and the corresponding relation between the interference level in the base station; Again according to the corresponding relation between interference level and the interference threshold, the corresponding interference threshold of confirming of said interference level.
Second step: the magnitude relationship between said interference parameter that relatively receives and the said definite interference threshold.
Step 103: when the said interference parameter that receives is not more than the interference threshold of the PMI correspondence that receives, utilize definite channel and the terminal of PMI that receives to communicate.
In step 103; When the comparative result between the said interference parameter that the receives interference threshold corresponding with the PMI that receives is not more than the latter for the former; Confirm the definite channel proper base station and the communication between terminals of PMI of terminal to report; That is to say that the channel that uses PMI to confirm between base station and the terminal communicates and the bigger situation of interference suffered in the communication process can not occur, can guarantee base station and communication between terminals quality; Therefore, utilize between base station and the terminal between channel that said PMI confirms and the terminal and communicate.
Step 104: confirm that corresponding interference threshold is not less than the PMI of interference parameter, and send the PMI that confirms that the channel that indicating terminal utilizes said definite PMI to confirm communicates to the terminal.
In step 104; When the comparative result between the said interference parameter that the receives interference threshold corresponding with the PMI that receives for the former during greater than the latter; Confirm the definite improper base station of channel and the communication between terminals of PMI of terminal to report; That is to say that the channel that uses PMI to confirm between base station and the terminal communicates and the bigger situation of interference suffered in the communication process may occur, can't guarantee base station and communication between terminals quality; Therefore, needing the base station is that new PMI is redistributed at the terminal.
Particularly, the base station is that the method that new PMI is redistributed at the terminal is:
The first step: the interference threshold of confirming to be not less than the interference parameter of terminal to report.
The interference threshold identical with the interference parameter of terminal to report confirmed on more excellent ground.
Second step; According to the PMI of this locality storage and the relation between the interference threshold, confirm the PMI that said interference threshold is corresponding.
Through embodiment one scheme; PMI that receiving terminal reports and interference parameter; According to the corresponding relation between PMI and the interference threshold, whether the interference parameter of judging terminal to report greater than the corresponding interference threshold of the PMI that reports, at said interference parameter during greater than the corresponding interference threshold of the PMI that reports; The definite channel of PMI of confirming terminal to report is not suitable for current communication environment; And confirm that again corresponding interference threshold is not less than the PMI of interference parameter, and send the PMI that confirms to the terminal, the channel that indicating terminal utilizes said definite PMI to confirm communicates; Avoid base station and the terminal bigger problem of suffered interference when communicating, improved base station and communication between terminals quality.
Embodiment two:
As shown in Figure 2, be the schematic flow sheet of a kind of method for communicating of present embodiment two.Present embodiment two is detailed descriptions of each step of present embodiment one, and said method comprises:
Step 201: in cycle report stage of communication process, a PMI and a plurality of interference parameter that receiving terminal reports.
In this step 201, base station and communication between terminals process are divided into two stages, and a stage is the report stage, perhaps is called negotiation phase; Another stage is the transmission stage, perhaps is called transmission phase signal.Usually, can base station and the communication between terminals process cycle of being divided into be carried out.
Said a plurality of interference parameter is meant at least one interference parameter.
In cycle report stage, the terminal is measured common down channel according to the pilot signal that the base station issues, and confirms that a PMI reports the base station; Because the base station need be confirmed the PMI that reports and whether be fit to base station and communication between terminals, can require the terminal in cycle report stage, reports a plurality of interference parameters; Also can be that terminal an interference parameter of in cycle report stage, gathering a plurality of different times and a PMI who confirms report the base station.
Step 202:, confirm the corresponding interference threshold of PMI that receives according to the corresponding relation between PMI and the interference threshold.
Wherein, the interference threshold that said PMI is corresponding is the set of the numerical value in an expression interval.
In step 202, the corresponding interference level of PMI that receives is confirmed according to the corresponding relation between PMI and the interference level in the base station; According to the corresponding relation between interference level and the interference threshold, confirm the interference threshold that said interference level is corresponding again, the interference threshold that the PMI that promptly receives is corresponding.
Step 203: judge each interference parameter that receives successively whether greater than the interference threshold of confirming, when greater than the number of the interference parameter of the interference threshold of confirming during greater than threshold value, execution in step 204; Otherwise, execution in step 205.
Wherein, said threshold value is N, and said N is a positive integer, and the size of N is confirmed according to actual needs, do not done concrete qualification here.
In step 203,, therefore, all compare with the interference threshold of confirming to each interference parameter of gathering because in the step 201, a plurality of interference parameters have constantly been gathered the different of report stage in the terminal.
Particularly, when each interference parameter compares with the interference threshold of confirming, wherein, judge that whether the said interference parameter that receives is greater than the maximum in the interference threshold interval of the PMI correspondence that receives to each terminal; Perhaps, judge that the said interference parameter receive is whether greater than the minimum value in the corresponding interference threshold interval of the PMI that receives; Perhaps, whether judge the said interference parameter that receives greater than a certain numerical value in the interference threshold interval of the PMI correspondence that receives, and write down the number of times of said interference parameter greater than the interference threshold of confirming.
Step 204: greater than the number of the interference parameter of the interference threshold of confirming during greater than threshold value, the interference parameter of confirming to receive is greater than the corresponding interference threshold of the PMI that receives, execution in step 206.
In step 204 since greater than the number of the interference parameter of the interference threshold of confirming greater than threshold value, explain then that in cycle report stage the suffered disturbed condition in terminal is more serious, the free PMI in terminal will be not suitable for base station and communication between terminals.
Step 205: when the number greater than the interference parameter of the interference threshold of confirming is not more than threshold value, confirm that the interference parameter that receives is not more than the corresponding interference threshold of PMI that receives, execution in step 210.
In step 205, owing to be not more than threshold value, explain then that in cycle report stage the suffered disturbed condition in terminal is slight relatively greater than the number of the interference parameter of the interference threshold of confirming, the free PMI in terminal possibly be fit to base station and communication between terminals.
Step 206: confirm that corresponding interference threshold is not less than the PMI of interference parameter.
In step 206, according to the corresponding relation between PMI and the interference level, and the corresponding relation between interference level and the interference threshold, confirm that corresponding interference threshold is not less than the PMI of interference parameter.
Step 207: judge to report in the terminal of identical PMI and interference parameter, receive the quantity of interfered with terminal whether to reach setting threshold, if then execution in step 208; Otherwise, execution in step 209.
Wherein, the said interference parameter that be meant by interfered with terminal to report is greater than the terminal of the corresponding interference threshold of the PMI that reports.
In step 207, judge to report in the terminal of identical PMI and interference parameter, when receiving the quantity of interfered with terminal to reach setting threshold, can adopt whole switching way switched by the PMI strategy of interfered with terminal, can save the communication resource like this.
Step 208: when receiving the quantity of interfered with terminal to reach setting threshold; Report the terminal of identical PMI and interference parameter to send PMI and the setting cycle T that satisfies each terminal interference parameter demand to all; And indicating terminal reports interference parameter in said T; And when the interference parameter that reports was not more than the interference threshold of the PMI correspondence that sends to this terminal, the channel that utilizes said definite PMI to confirm communicated.
Wherein, said setting threshold can be confirmed according to the base station current working state, also can set according to practical experience, and the size of concrete setting threshold is not done qualification.
In step 208; When the base station confirms to receive the quantity of interfered with terminal to reach setting threshold; Explain that the current terminal of identical PMI that reports receives interference ratio more serious; Interference parameter according to the terminal to report that reports identical PMI is different, for it distributes each terminal interference parameter corresponding PMI and setting cycle T.
The said PMI that satisfies each terminal interference parameter demand is meant according to the corresponding relation between PMI and the interference threshold, confirms that corresponding interference threshold is not less than the PMI of interference parameter.
Need to prove, when being terminal distribution PMI, existing and distribute identical PMI to give the situation of different terminal,, specifically do not limit distribution result as long as satisfy each terminal interference parameter demand.
The base station is that different terminal distributes setting cycle T when being terminal distribution PMI, said T can be identical, also can be different, and purpose is to verify the base station is whether the PMI of terminal distribution is fit to base station and communication between terminals, and concrete grammar is:
The first step: indicating terminal reports M interference parameter at said T in the cycle.
Wherein, said setting cycle T confirms that according to the requirement of communication the length of cycle T is not done concrete qualification.
Said M is a positive integer, the number of the interference parameter that gather in the cycle at T at the expression terminal.
Concrete, the terminal is divided into M time period with the T cycle, when each arrival, gathers the suffered interference in terminal in this time period as an interference parameter time period.
Second step:, confirm the corresponding interference threshold of PMI that distributes according to PMI that distributes and the corresponding relation between the interference threshold.
The 3rd step: whether judge interference parameter that T reports in the cycle successively greater than the interference threshold of confirming, when during greater than threshold value, continuing execution in step 204 greater than the number of the interference parameter of the interference threshold of confirming; Otherwise the channel that utilizes said definite PMI to confirm communicates.
Step 209: when receiving the quantity of interfered with terminal not reach setting threshold; Send PMI and the setting cycle T that confirms to receiving interfered with terminal; And indication receives interfered with terminal in said T, to report interference parameter; And when the interference parameter that reports was not more than the interference threshold that sends to this PMI that receives interfered with terminal correspondence, the channel that utilizes said definite PMI to confirm communicated.
In this step 209, when the base station confirms to receive the quantity of interfered with terminal not reach setting threshold, explain that it not is especially severe that current all terminals that report identical PMI receive to disturb, only be required to be to receive interfered with terminal to distribute PMI and the setting cycle T that confirms; Operation afterwards is identical with step 208, no longer describes.
Be with the difference of step 208, in step 209, realization be the adjustment that receives interfered with terminal PMI individually.
Step 210: utilize definite channel and the terminal of PMI that receives to communicate.
