The first obtain manner: first kind terminal and Equations of The Second Kind terminal be pilot signal transmitted on different running time-frequency resource respectively, is received by first kind antenna and Equations of The Second Kind antenna;

In this approach, main employing be make the base station being provided with first kind antenna and Equations of The Second Kind antenna be in half-duplex state, the i.e. pilot signal transmitted on different running time-frequency resource by first kind terminal and Equations of The Second Kind terminal, first kind antenna and Equations of The Second Kind antenna receive the pilot signal sent.

It should be noted that, because uplink channel information and descending channel information have reciprocity, for the first channel information between first kind terminal and first kind antenna, namely first kind terminal is identical to channel information and the first kind antenna of first kind antenna to the channel information of first kind terminal, is the first channel information.Based on above-mentioned principle, the base station being provided with first kind antenna and Equations of The Second Kind antenna can be made equally to be in half-duplex state, and wherein, first kind antenna and Equations of The Second Kind antenna are all in transmission working method, and on different running time-frequency resource pilot signal transmitted, received by first kind terminal and Equations of The Second Kind terminal.To obtain the first channel information between first kind terminal and first kind antenna, obtain the measurement result that first kind terminal returns after receiving the pilot signal of first kind antenna transmission, according to the first channel information between measurement result determination first kind terminal and first kind antenna.

The second obtain manner: the pilot signal transmitted while that first kind antenna and first kind terminal being on the first running time-frequency resource, received by Equations of The Second Kind antenna and Equations of The Second Kind terminal, the pilot signal transmitted while that Equations of The Second Kind antenna and first kind terminal being on the second running time-frequency resource, is received by first kind antenna and Equations of The Second Kind terminal;

In this approach, what mainly adopt is make the base station being provided with first kind antenna and Equations of The Second Kind antenna be in full duplex state, and namely on any running time-frequency resource, two class antennas of base station are all in the working method that a class sends, an other class receives.Based on uplink channel information and descending channel information, there is reciprocity equally, under ensureing that base station is in the prerequisite of full duplex state, when obtaining the first channel information between first kind terminal and first kind antenna, second channel information, the 3rd channel information between Equations of The Second Kind terminal and first kind antenna, the 4th channel information between Equations of The Second Kind terminal and Equations of The Second Kind antenna between first kind terminal and Equations of The Second Kind antenna, different obtain manners can also be selected according to following table 1:

Table 1

	First kind antenna	Equations of The Second Kind antenna	First kind terminal	Equations of The Second Kind terminal
					Pattern 1	Send	Receive	Receive	Send
Pattern 2	Send	Receive	Send	Receive
					Mode 3	Receive	Send	Receive	Send
Pattern 4	Send	Receive	Send	Receive

In upper table, any one pattern first kind antenna and Equations of The Second Kind antenna are all in a class and send, the working method of another kind of reception, two kinds of patterns are selected arbitrarily from above-mentioned pattern 1 to pattern 4, on different running time-frequency resources, allow to be in two kinds of patterns selecting and send the antenna of working method and terminal pilot signal transmitted, be in the antenna and terminal receives pilot signals that receive working method, the first channel information between first kind terminal and first kind antenna can be obtained, second channel information between first kind terminal and Equations of The Second Kind antenna, the 3rd channel information between Equations of The Second Kind terminal and first kind antenna, the 4th channel information between Equations of The Second Kind terminal and Equations of The Second Kind antenna.Based on above-mentioned principle, when the base station being provided with first kind antenna and Equations of The Second Kind antenna is in full duplex state, according to permutation and combination process, one has the object that 6 kinds of modes can realize obtaining channel information.From the working method of antenna and terminal under often kind of pattern, in the second way, selection be pattern 2 and mode 3.The mode of other remaining 5 kinds of acquisition channel informations, with reference to the operation principle of the second way, can repeat no more herein.

In addition, can also be calculated the up-downgoing signal to noise ratio under often kind of pattern by channel information, can be weighed the performance of system by signal to noise ratio, the present embodiment does not do concrete restriction to this yet.

Such as, as shown in Figure 7, the first channel information between first kind terminal and first kind antenna is g1, second channel information between first kind terminal and Equations of The Second Kind antenna is g2, the 3rd channel information between Equations of The Second Kind terminal and first kind antenna is h1, the 4th channel information between Equations of The Second Kind terminal and Equations of The Second Kind antenna is h2.Can adopt as the formula in following table 2 calculates when calculating the up-downgoing signal to noise ratio under often kind of pattern:

Table 2

Wherein, P _bSfor the power of transmission channel, k _uEfor interference channel information, P _uEfor the power of interference channel, σ is noise factor.

It should be noted that, because the base station most of the time is all in full duplex state, namely in two class antennas, a class is in transmission working method, another kind ofly be in reception working method, normal send mode can be passed through in base station, pilot signal is sent together with signal to be sent, and Received signal strength and measurement result, thus obtain different channel informations.Based on above-mentioned principle, the second way goes for base station conventional operational state, and first kind of way is in half-duplex state due to base station, thus goes for some special occasions.

The present embodiment does not do concrete restriction to the mode of the 5th channel information obtaining first kind terminal and Equations of The Second Kind terminal room, includes but not limited to the following two kinds mode:

First kind of way: the 5th channel information of the Equations of The Second Kind terminal that reception Equations of The Second Kind terminal is fed back after receiving the pilot signal of first kind terminal transmission and first kind terminal room;

The second way: the 5th channel information of the first kind terminal that reception first kind terminal is fed back after receiving the pilot signal of Equations of The Second Kind terminal transmission and Equations of The Second Kind terminal room.

Owing to there is reciprocity based on uplink channel information and descending channel information equally, therefore, can be received by first kind terminal pilot signal transmitted, Equations of The Second Kind terminal respectively according to above-mentioned two kinds of working methods, or by Equations of The Second Kind terminal pilot signal transmitted, first kind terminal receives, thus obtains the 5th channel information of first kind terminal and Equations of The Second Kind terminal room.

602: calculate the up bit error rate of often kind of default antenna mode of operation and descending bit error rate according to the first channel information, second channel information, the 3rd channel information, the 4th channel information and the 5th channel information;

Default antenna mode of operation mainly contains two kinds, namely first kind antenna is in and sends working method, Equations of The Second Kind antenna and be in reception working method, or Equations of The Second Kind antenna is in and sends working method, first kind antenna is in reception working method, and the present embodiment is not specifically limited this.

The present embodiment is not to according to the first channel information, second channel information, 3rd channel information, 4th channel information and the 5th channel information calculate the up bit error rate of often kind of default antenna mode of operation and the mode of descending bit error rate does concrete restriction, include but not limited to: according to the first channel information, second channel information, 3rd channel information, 4th channel information and the 5th channel information determine total bit number that often kind of default antenna mode of operation is up, up total errored bit number, descending total bit number and descending errored bit number, up total errored bit number can be obtained up bit error rate divided by up total bit number, descending total errored bit number can be obtained descending bit error rate divided by descending total bit number.

603: calculate the up bit error rate of often kind of default antenna mode of operation and descending bit error rate sum, using default antenna mode of operation corresponding for minimum of computation result as the antenna operating mode chosen.

From the table 1 in step 602, often kind of default antenna mode of operation correspond to two kinds of patterns respectively, first kind antenna can be sent, Equations of The Second Kind antenna receive as the first antenna operating mode, using first kind antenna receive, Equations of The Second Kind antenna send as the second antenna operating mode.Wherein, the first antenna operating mode correspond to two kinds of patterns, is respectively pattern 1 and correspond to two kinds of patterns equally with pattern 2, second antenna operating mode, be respectively mode 3 and pattern 4.

Therefore, first can calculate the up bit error rate under often kind of pattern and descending bit error rate sum, up bit error rate relatively under arrangement often kind of pattern and descending bit error rate sum, the pattern corresponding according to minimum value wherein determines the antenna operating mode chosen.

Calculate the up bit error rate of often kind of pattern and descending bit error rate sum, and select pattern corresponding to minimum value wherein can represent with following formula:

i = \arg \min_{i = 1,2,3,4} {{BER}_{UL}^{(i)} + {BER}_{DL}^{(i)}}

Wherein, the label that i intermediate scheme is corresponding, the corresponding respectively label of pattern 1 to pattern 4 is 1,2,3,4, represent the up bit error rate under pattern label is i situation, represent the descending bit error rate when pattern label is i. make certain functional obtain the function of minimum value, namely get the label of the up bit error rate pattern corresponding with the minimum value of descending bit error rate sum.

Such as, if determine under four kinds of patterns, the label of the pattern that up bit error rate is corresponding with the minimum value of descending bit error rate sum is 1, then determine pattern 1 when, and up bit error rate and descending bit error rate sum can reach minimum value.Antenna operating mode due to pattern 1 correspondence is the first antenna operating mode, now, using the first antenna operating mode as the antenna operating mode chosen.

It should be noted that, actual in carrying out Signal transmissions, in order to ensure optimum performance, need to combine the selection considering user's matching method and antenna operating mode, wherein, user's matching method refers to when measuring channel information, selects terminal corresponding to which user to be in transmission working method, and terminal corresponding to which user is in reception working method.The words of two kinds of factors while of owing to considering above-mentioned, whole processing procedure can cause very large pilot-frequency expense, therefore, more feasible method is separately processed the selection of user's pairing and antenna operating mode, the method adopting the present embodiment to provide again after user's pairing is selected antenna operating mode, completes the selection course of complicated antenna operating mode by being divided into two steps simplified.Wherein, the mode of user's pairing can have the following two kinds matching method:

The first matching method: the possibility traveling through all users pairing, comprise the possibility of each user's up-downgoing business, namely the terminal that each user is corresponding be for transmission working method or receive working method, and select make base station send signal time there is the antenna operating mode of minimum up bit error rate and descending bit error rate sum or there is the Antenna Operation mode of maximum up-link capacity and downlink capacity sum;

The second matching method: first determine that each user is uplink service or downlink business, then determine that the user of which uplink service and the user of downlink business match, and select make base station send signal time there is the antenna operating mode of minimum up bit error rate and descending bit error rate sum or there is the Antenna Operation mode of maximum up-link capacity and downlink capacity sum.

It should be noted that, because the first matching method take into account all possibilities, thus can carry out optimal user pairing and select corresponding antenna operating mode, thus ensureing optimum performance.But because situation possible in the first matching method is very many, spend expense larger when processing.And in the second matching method, owing to first determining the pairing between the up-downgoing business of each user and user, thus situation is less, when processing, the expense of cost is also relatively less.In a practical situation, can select as required, the present embodiment does not do concrete restriction to this.

Such as, in the first matching method, if there are 10 users, then each use has the possibility of up-downgoing business per family, so just has the 10 power kinds possibilities of 2, adds the possibility of follow-up pairing, possibility is altogether very many, and the expense spent when causing processing multiple possibility is larger.And after the pairing of the second matching method between the up-downgoing determining each user and user, at this time only have a kind of possibility, therefore, the expense spent during process is less.
