In this approach, mainly using making the base station for being equipped with first kind antenna and the second class antenna be in full duplex State, i.e., on any running time-frequency resource, two class antennas of base station are in a kind of transmission, in addition a kind of received working method. Reciprocity is equally had based on uplink channel information and descending channel information, is in the premise of full duplex state in guarantee base station Under, obtaining the between the first channel information between the first Terminal Type and first kind antenna, the first Terminal Type and the second class antenna Between third channel information, the second Terminal Type and the second class antenna between two channel informations, the second Terminal Type and first kind antenna When four channel informations, different acquisition modes can also be selected according to the following table 1:
Table 1
First kind antenna Second class antenna First Terminal Type Second Terminal Type
Mode 1 It sends It receives It receives It sends
Mode 2 It sends It receives It sends It receives
Mode 3 It receives It sends It receives It sends
Mode 4 It sends It receives It sends It receives
In upper table, any one mode first kind antenna and the second class antenna are in a kind of transmission, another kind of received Working method arbitrarily selects both of which into mode 4 from above-mentioned mode 1, on different running time-frequency resources, allows two kinds of selection In the antenna and terminal pilot signal transmitted for sending working method in mode, connect in the antenna for receiving working method with terminal Pilot signal is received, the first channel information, the first Terminal Type and the second class between the first Terminal Type and first kind antenna can be obtained Second channel information, the second Terminal Type between antenna and the third channel information between first kind antenna, the second Terminal Type and second The 4th channel information between class antenna.Based on the above principles, when the base station for being equipped with first kind antenna and the second class antenna is in When full duplex state, according to permutation and combination process, one, which shares 6 kinds of modes, may be implemented to obtain the purpose of channel information.By every kind For the working method of antenna and terminal under mode it is found that in the second way, selection is mode 2 and mode 3.Other residues 5 kinds acquisition channel information mode, can refer to the second way working principle, details are not described herein again.
In addition, the uplink and downlink signal-to-noise ratio under each pattern can also be calculated by channel information, it can also by signal-to-noise ratio It is measured with the performance to system, the present embodiment is not especially limited this.
For example, as shown in fig. 7, the first channel information between the first Terminal Type and first kind antenna is g1, the first Terminal Type Second channel information between the second class antenna is g2, the third channel information between the second Terminal Type and first kind antenna be h1, The 4th channel information between second Terminal Type and the second class antenna is h2.It can when calculating the uplink and downlink signal-to-noise ratio under each pattern To be calculated using such as the formula in the following table 2:
Table 2
Wherein, PBSFor the power of transmission channel, kUEFor interference channel information, PUEFor the power of interference channel, σ is noise Coefficient.
It should be noted that one kind is in i.e. two class antennas since the base station most of the time is in full duplex state Send working method, it is another kind of in receiving working method, base station can by normal sending method, by pilot signal with it is pending The signal sent is sent together, and receives signal and measurement result, to obtain different channel informations.Based on the above principles, The second way can be adapted for base station conventional operational state, and first way is since base station is in half-duplex state, thus It can be adapted for certain special occasions.
The present embodiment does not limit the mode for obtaining the 5th channel information between the first Terminal Type and the second Terminal Type specifically Determine, including but not limited to the following two kinds mode:
First way: the second Terminal Type is fed back after the pilot signal for receiving the transmission of the first Terminal Type second is received 5th channel information of Terminal Type and first kind terminal room；
The second way: the first Terminal Type is fed back after the pilot signal for receiving the transmission of the second Terminal Type first is received The 5th channel information between Terminal Type and the second Terminal Type.
There is reciprocity due to being equally based on uplink channel information and descending channel information, it can be according to above-mentioned two Kind working method is received by the first Terminal Type pilot signal transmitted, the second Terminal Type respectively, or is led by the transmission of the second Terminal Type Frequency signal, the first Terminal Type receive, to obtain the 5th channel information between the first Terminal Type and the second Terminal Type.
602: according to the first channel information, second channel information, third channel information, the 4th channel information and the 5th channel Information calculates the uplink bit error rate and downlink bit error rate of every kind of default antenna operating mode；
There are mainly two types of default antenna operating modes, i.e., first kind antenna is at transmission working method, the second class antenna Reception working method, this reality are in transmission working method, first kind antenna in receiving working method or the second class antenna Example is applied to be not specifically limited in this embodiment.
The present embodiment not to according to the first channel information, second channel information, third channel information, the 4th channel information and The mode of uplink bit error rate and downlink bit error rate that 5th channel information calculates every kind of default antenna operating mode is made specifically It limits, including but not limited to: according to the first channel information, second channel information, third channel information, the 4th channel information and the Five channel informations determine the total bit number of every kind of default antenna operating mode uplink, total errored bit number of uplink, downlink always than The errored bit number of special number and downlink, by total errored bit number of uplink divided by the available uplink errored bit of total bit number of uplink Rate, by total errored bit number of downlink divided by the available downlink bit error rate of total bit number of downlink.
603: the sum of uplink bit error rate and downlink bit error rate of every kind of default antenna operating mode are calculated, it will most subtotal The corresponding default antenna operating mode of result is calculated as the antenna operating mode chosen.
It, can be by first by the table 1 in step 602 it is found that every kind of default antenna operating mode respectively corresponds both of which Class antenna is sent, the second class antenna receives and is used as first antenna operating mode, first kind antenna is received, the second class antenna is sent As the second antenna operating mode.Wherein, first antenna operating mode corresponds to both of which, respectively mode 1 and mode 2, Second antenna operating mode equally corresponds to both of which, respectively mode 3 and mode 4.
Therefore, the sum of uplink bit error rate and the downlink bit error rate under each pattern can be first calculated, arrangement is compared The sum of uplink bit error rate and downlink bit error rate under each pattern are determined according to the corresponding mode of minimum value therein and are chosen Antenna operating mode.
In the sum of uplink bit error rate and the downlink bit error rate for calculating each pattern, and select minimum value therein corresponding Mode can be indicated with following formula:
Wherein, the corresponding label of i intermediate scheme, mode 1 is corresponding marked as 1,2,3,4 to mode 4,Table Show in mode marked as the uplink bit error rate under i situation,Indicate that downlink in the case of mode is marked as i misses ratio Special rate.So that some functional obtains the function of minimum value, that is, take the sum of uplink bit error rate and downlink bit error rate The corresponding mode of minimum value label.
Such as, however, it is determined that under four kinds of modes, uplink bit error rate is corresponding with the minimum value of the sum of downlink bit error rate Mode marked as 1, it is determined that in the case of mode 1, the sum of uplink bit error rate and downlink bit error rate can reach minimum Value.Due to the corresponding antenna operating mode of mode 1 be first antenna operating mode, at this point, using first antenna operating mode as The antenna operating mode of selection.
It should be noted that it is practical when carrying out signal transmission, in order to guarantee optimum performance, needs to combine consideration user and match Selection to mode and antenna operating mode, wherein user's matching method refers to which selects when measuring channel information The corresponding terminal of user, which is in, sends working method, and the corresponding terminal of which user, which is in, receives working method.On considering State at the same two kinds of factors if, entire treatment process will lead to very big pilot-frequency expense, and therefore, more feasible method is will to use Family pairing and the selection of antenna operating mode are separately handled, again using method provided in this embodiment to day after user's pairing Line operating mode is selected, and the selection course of complicated antenna operating mode is completed by being divided into two simplified steps.Its In, the mode of user's pairing can have the following two kinds matching method:
The first matching method: traversing the possibility of all user's pairings, including a possibility that each user's uplink and downlink business, The corresponding terminal of i.e. each user and is selected so that base station is believed sending for sending working method or receive working method Number when antenna operating mode with the sum of minimum uplink bit error rate and downlink bit error rate or there is maximum up-link capacity With the Antenna Operation mode of the sum of downlink capacity；
Second of matching method: it first determines that each user is uplink service or downlink business, which uplink is then determined The user of business and the user of downlink business match, and selecting so that base station is when sending signal, there is minimum uplink to miss ratio The antenna operating mode of the sum of special rate and downlink bit error rate or antenna with the sum of maximum up-link capacity and downlink capacity Working method.
It should be noted that since the first matching method considers a possibility that all, thus can be carried out best use Family matches and selects corresponding antenna operating mode, to guarantee optimum performance.But due to possible in the first matching method Situation is very more, spends expense bigger when being handled.And in second of matching method, due to first determining each use Pairing between the uplink and downlink business at family and user, thus situation is less, the expense spent when being handled is also relatively It is few.In a practical situation, it can according to need and selected, the present embodiment is not especially limited this.
For example, in the first matching method, if there is 10 users, each possibility for having uplink and downlink business per family, Thus have 2 10 power kinds may, a possibility that adding subsequent pairing, in total a possibility that it is very more, cause to handle more The expense spent when kind possibility is bigger.And second of matching method is between the uplink and downlink and user for determining each user After pairing, at this time only a kind of possibility, therefore, the expense that when processing spends are smaller.
Method provided in this embodiment, by obtaining the first Terminal Type and the second Terminal Type and first kind antenna and the second class Channel information between antenna, and the channel information between the first Terminal Type and the second Terminal Type is obtained, believed according to the channel got Breath calculates the uplink and downlink parameter under every kind of default antenna operating mode, according to the uplink and downlink parameter of every kind of default antenna operating mode Choose antenna operating mode.Due to that can be chosen according to channel information to antenna operating mode, it can adapt to letter The real-time change of road information, flexibility is preferable, and the efficiency for transmitting signal is higher.
