First characteristic of channel configured information is used to indicate that first terminal demodulates interference signal using the specific characteristic of channel, i.e., demodulate interference signal using first characteristic of channel in the present embodiment.First characteristic of channel configured information can directly carry the relevant information of first characteristic of channel, or indicate that first terminal selects first required characteristic of channel etc. from several characteristics of channel that the-network equipment is sent to first terminal in advance, it can specifically be set according to actual needs. First characteristic of channel in the present embodiment includes at least one of following information：The delay spread for the channel that signal is undergone（Delay Spread), the doppler spread (Doppler Spread) of channel, the Doppler frequency shift of channel（Doppler Shift), the average gain (Average gain) of channel, the average delay (Average delay) of channel

Step 102, the signal received is demodulated according to first characteristic of channel.

Wherein, signal includes interference signal and useful signal.First terminal is demodulated according to first characteristic of channel to the signal received, can be specifically that first terminal carries out coherent demodulation according to the first characteristic to the signal received, to delete interference signal, i.e., demodulated from signal after interference signal, deletion action is carried out to it.How to be demodulated according to the characteristic of channel and belong to prior art, will not be repeated here.

Useful signal is the signal for needing to receive first terminal, for example in Long Term Evolution (Long-Term Evolution, LTE) PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel designed in system）Signal or EPDCCH (Enhanced Physical Downlink Control Channel, enhanced Physical Downlink Control Channel) signal, it can be used for transmission data or signaling.Interference signal is the signal interfered to useful signal.

It is to be noted that, first terminal first can first delete interference signal according to first characteristic of channel, then re-demodulation goes out useful signal, first terminal can also simultaneously carry out deleting interference signal and demodulate the operation of useful signal, or first terminal uses multiple-input, multiple-output (Multiple Input Multiple Output, MIMO) or multi-user's multiple-input, multiple-output to interference signal and useful signal（Multiple-User Multiple Input Multiple Output, MU-MIMO) combine the operation received.In the present embodiment, the execution sequence of the demodulation of the demodulation useful signal of interference signal is not limited, can specifically be set according to actual needs.

The present embodiment provides a kind of method of wireless signal processing based on embodiment one.

The present embodiment mainly carries out concrete example explanation to step 101, and any one specific that may be selected in the following manner realizes step 101. Mode A:Receive that the first network equipment of first terminal ownership sends the says characteristic configured information, first characteristic of channel configured information includes first characteristic of channel of the interference signal transmitted by first characteristic of channel or at least one second terminal for the interference signal that at least one second network equipment is sent, and first terminal determines first characteristic of channel of interference signal according to first characteristic of channel configured information.

In practical application, other network equipments are likely to result in first terminal to be significantly interfered with.As shown in Figure 2 A, when the network equipment 211 of first network equipment 210 and second sends signal to first terminal 212 and second terminal 213 respectively simultaneously, the signal transmitted by first network equipment 210 can be sent to the signal of second terminal 213 to second network equipment 211；^ is disturbed.In addition, other terminals can also cause to significantly interfere with to the first terminal.As shown in Fig. 2 B, on some time point, first network equipment 220 sends downstream signal to first terminal 222, second terminal 223 sends out i row signals to second network equipment 221 simultaneously, if first terminal 222 and the letter of second terminal 223 hand over small, the downstream signal that the first network equipment 220 that the upward signal that second terminal 223 is sent can be received to first terminal 222 is sent causes obvious interference.

In the present embodiment, second terminal is different from first terminal, determines that the mode of second terminal is not limited, for example, can be terminal of the absolute value less than predetermined threshold value with the channel fading of first terminal, and the predetermined threshold value can be set according to actual needs.For example, the instruction for the first network equipment that first terminal is belonged to according to first terminal, measure the RS that the RS and second terminal of the transmission of first network equipment are sent, the information for the RS that first network equipment only can send the second terminal notifies first terminal, RS temporal information, frequency information etc. are sent including second terminal, further the identification information of second terminal can also be notified first terminal, and report the corresponding Reference Signal Received Power of the two RS（Reference Signal Received Power, RSRP), then first network equipment can just compare the two RSRP difference, when the ^ ^ values of the difference are less than predetermined threshold value, then it is assumed that second terminal causes to significantly interfere with to first terminal；Or first network equipment indicates that first terminal measures a certain RS, when the corresponding RSRP of the RS are higher than a certain threshold value, then first terminal then sends message to first network equipment, report that the RS causes to significantly interfere with to first terminal, first network equipment can then determine that the corresponding transmission sources of the RS (i.e. second terminal) cause to significantly interfere with to first terminal according to the information.

It is to be noted that, " ownership " in the first network equipment of first terminal ownership illustrated by the present embodiment represents that first network equipment can be transmitted signaling, data to first terminal or receive the operation such as signaling, data that first terminal is sent, i.e. first terminal can be communicated with first network equipment, be not offered as first terminal and be arranged in first network equipment.

Mode B:Receive that the first network equipment of first terminal ownership sends the says characteristic configured information；According to the first characteristic of channel configured information in the multiple characteristics of channel obtained in advance, select and first terminal First characteristic of channel of corresponding interference signal.

Multiple characteristics of channel can be sent to first terminal in advance from first network equipment, can specifically be sent using semi-static signaling or multiple characteristics of channel are got by first terminal measurement RS.Then, first network equipment can select to send the first characteristic of channel configured information to first terminal using dynamic signaling.First terminal selects first characteristic of channel of interference signal according to first characteristic of channel configured information from multiple characteristics of channel.

In the prior art, signaling includes semi-static signaling and dynamic signaling.First terminal is before new semi-static signaling is received, and first terminal can be always using the information indicated by the semi-static signaling, such as RRC (Radio Resource Control, wireless heterogeneous networks）Signaling.Dynamic signaling is characterised by that a dynamic signaling only corresponds to limited one or many transmission, such as PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) signaling.First network equipment first sends the larger characteristic of channel of information content using semi-static signaling to first terminal, then indicates that first terminal uses one of characteristic of channel by the less dynamic signaling of information content, can reduce signaling consumption, mitigate the burden of network.

The first characteristic of channel configured information in mode B can be the combination of bit, numeral, letter or numeral and letter.Particular content of the first terminal according to represented by preset rules can know the first characteristic of channel configured information.For example, when the first characteristic of channel configured information is 1, first characteristic of channel as interference signal using the 1st characteristic of channel of selection in multiple characteristics of channel can be represented.This it is pre- it should be noted that, for the sequence of multiple characteristics of channel, can be determined by the bit position information of each characteristic of channel, or pre-set a set of characteristic of channel sequence, it specifically can according to actual needs be set, will not be repeated here.

Mode C:The first characteristic of channel configured information that the first network equipment of first terminal ownership is sent is received, the first characteristic of channel configured information is used to indicate that first terminal is used and useful signal identical characteristic of channel demodulated signal；

According to the first characteristic of channel configured information determine interference signal first characteristic of channel be and the useful signal identical characteristic of channel.

Using multi-user's multiple-input, multiple-output（Multiple-User Multiple Input Multiple Output, MU-MIMO) in the system of technology, interference signal can also come from the same network equipment with useful signal, now be possible to first characteristic of channel and useful signal for occurring interference signal Second channel characteristic identical situation.In this case, first terminal can just take the second channel characteristic of useful signal to demodulate interference signal, and delete the interference signal.

Mode D:Receive the first characteristic of channel configured information that the first network equipment of first terminal ownership is sent；According to the first characteristic of channel configured information, from first terminal by selecting first characteristic of channel of interference signal in measuring multiple characteristics of channel that RS is got.

First terminal can obtain the characteristic of channel by measuring RS signals, can obtain multiple characteristics of channel by a RS or obtain one by a RS to say characteristic, i.e., be obtained by measuring multiple RS and say characteristic more.How to belong to prior art by measuring the RS acquisitions characteristic of channel, no longer praise state herein.The first characteristic of channel configured information in mode D can be the combination of bit, numeral, letter or numeral and letter, and according to preset rules, first terminal can know which is the characteristic of channel corresponding with first characteristic of channel configured information.For example, when ￡ characteristics configured information is 1, shows to use by the 1st RS of measurement the characteristic of channel that obtains as the and say characteristic.

It is pointed out that measurement RS is measured by the configuration information row of the RS for measurement, the configuration information for the RS of measurement includes the one or more in following information：RS frequency information, RS temporal information, RS power information, RS sequence information, RS speech breath, RS antenna port information etc..

Mode Ε:Receive the first characteristic of channel configured information that the first network equipment of first terminal ownership is sent；Accurate co-located (Quasi co-location) information of dry 4 outstanding signals is determined in the multiple RS for being used to measure obtained in advance configuration information according to the first characteristic of channel configured information；

According to the accurate co-located information of interference signal, first characteristic of channel of interference signal is determined.

Wherein, the first characteristic of channel configured information can be sent with ^ with dynamic signaling, and multiple RS for being used to measure configuration information can be sent using semi-static signaling.The accurate co-located information representation signal of the present embodiment is all from the identical network equipment with some CSI-RS, therefore the channel of these signals it is special ' mesh is same, i.e. these signal standards are co-located, are easy to UE the characteristic of channel and then to be handled according to determined by the measurement to the CSI-RS signal；In embodiments of the present invention, the accurate co-located information of interference signal is to represent that interference signal and some CSI-RS have the identical characteristic of channel, is easy to UE characteristics of channel according to determined by the measurement to the CSI-RS to handle interference signal.

First characteristic of channel configured information can be the combination of numeral, letter or numeral and letter.For example shown in table 1, indicate that interference signal and which RS standard are co-located using 2 signaling bits.Assuming that first terminal have received 4 RS, respectively the first RS, the 2nd RS, the 3rd RS and the 4th RS, the first characteristic of channel configured information represents that the corresponding relation of content is as shown in table 1 with it.

Table 1 First characteristic of channel configured information represents content

00 interference signal and the first RS standards are co-located

01 interference signal and the 2nd RS standards are co-located

10 interference signals and the 3rd RS standards are co-located

11 interference signals and the first RS in the accurate co-located tables 1 of the 4th RS, 2nd RS, 3rd RS and the 4th RS are actually one group of RS respectively, the RS with identical characteristic that group RS ^-network equipment is sent at some moment, for example with same period and time migration, occupy identical running time-frequency resource and/or use mutually homotactic multiple RS, its correspondence identical configuration information, the RS that this every group has identical characteristic is accordingly to be regarded as same RS in the embodiment of the present invention, it is same below, i.e. institute of the embodiment of the present invention '] some RS when, the RS with identical characteristic that consolidated network equipment is sent at some moment can be represented.I.e. first network equipment sends the configuration information of the RS for measurement to first terminal, and first terminal periodically measures corresponding RS to obtain the characteristic of channel according to the configuration information of the RS for being used for measurement, and concrete operations are bribery technology, and Bile is not stated herein.

Wherein, multiple RS with same period and time migration for example can be：Cycle is 5 Τ, time migration is 1 Τ Τ (Transmission Time Interval, Transmission Time Interval）, can be specifically numbering be 1,6,11...... Τ.Τ can specifically be set according to actual needs, such as 1 millisecond.First terminal learns the accurate co-located information ^ of interference signal according to table 1, it is possible to according to first characteristic of channel of the accurate co-located acquisition of information to interference signal.

First characteristic of channel configured information can also be 1 bit, specifically can be as shown in table 2.

Table 2

It can be seen that in 2, the of interference signal says characteristic and is possible to identical with useful signal, this is due to, in the system for having used MU-MIMO technologies, interference signal can also come from the same network equipment with useful signal, now, will occur first characteristic of channel of interference signal and the second channel characteristic identical situation of useful signal.

In addition, the first characteristic of channel configured information can not only indicate interference signal with which RS standard altogether Location, also may indicate that the mapping mode information of interference signal.

For example shown in Fig. 3 A and Fig. 3 B, the schematic diagram of respectively up DM RS and data-signal mapping mode information and the mapping mode information of descending DM RS and data-signal, that is Fig. 3 A are the schematic diagram for the up DM RS of demodulation and the mapping mode information of data-signal, and Fig. 3 B are the schematic diagram for the descending DM RS of demodulation and the mapping mode information of data-signal.Data-signal in the present embodiment is useful signal.Now, the first characteristic of channel configured information can use the signaling field of 2 bits, specifically can be as shown in table 3.So it is easy to flexibly indicate that interference signal is uplink interference signal or descending interference signal to first terminal, and reduces signaling consumption.If specific first terminal belongs to prior art according to the characteristic of channel of the DM RS and the mapping mode acquisition of information of data-signal of the demodulation data-signal, no longer go to live in the household of one's in-laws on getting married herein

Alternatively, with upper type it is multiple be used for measure RS configuration information at least include one be used for measure up RS configuration information.

The method of the corresponding wireless signal processing of the manner is particularly suitable for use in flexible duplex（Flexible

Duplex) in communication system, it is related to the emitter, the emitter of reception device or duplex, reception device of the different up-downlink directions of corresponding time-varying such as service adaptation, interference adaptation, resource adaptation, i.e. involved emitter or reception device can be with changes situations such as business, disturbed condition and the utilization of resources, correspondingly change the distribution of ascending resource or downlink resource, wherein ascending resource or downlink resource includes time and/or frequency resource.

Mode F:Before step 101, first terminal receives the first net of first terminal ownership first The configuration information and the mapping mode information of useful signal for the DM RS for being used to demodulate that network equipment is sent, and according to the second channel characteristic of the mapping mode acquisition of information useful signal.

Configuration information and the mapping mode information of useful signal for the DM RS of demodulation, and first characteristic of channel configured information can be issued respectively in different signalings, in the manner F, first network equipment first issues the configuration information and the mapping mode information of useful signal of the DM RS for demodulation to first terminal, so that first terminal gets the second channel characteristic of useful signal.So, the first characteristic of channel configured information that the first network equipment of the reception first terminal ownership in step 101 is sent is specifically included：The first characteristic of channel configured information that the first network equipment of first terminal ownership is sent is received, the first characteristic of channel configured information is used to indicate that first characteristic of channel is identical with second channel characteristic.

Here second channel characteristic is the characteristic of channel of useful signal.Mapping mode information in mode F is used for configuration information and the mapping mode information of useful signal for indicating the up DMRS that first terminal is used for demodulating, or using the configuration information and the mapping mode information of useful signal of the descending DM RS for demodulating.So, first terminal to obtain interference signal, and can delete the interference signal using second channel characteristic come demodulated signal.

Mode G:The configuration information and the mapping mode information of interference signal for the DM RS for being used to demodulate that first network equipment is sent are received, and according to first characteristic of channel of mapping mode acquisition of information interference signal.

In the manner G, just include the configuration information and the mapping mode information of interference signal of DM RS for demodulation in the first characteristic of channel configured information that first network equipment is sent, interference signal can just get first characteristic of channel of interference signal according to the mapping mode information.

Alternatively, in the present embodiment, before step 101, in addition to：

The type indication information of first terminal is sent to first network equipment, so that the-network equipment judges whether to send the first characteristic of channel configured information to first terminal according to type indication information, type indication information is used to indicate whether first terminal can recognize the first characteristic of channel configured information.Specifically, type indication information can include the identification information of the interference deletion ability label information of first terminal or the operating system of first terminal.

Because first terminal is possible to delete without interference（Interference Cancellation, interference is deleted）Ability, first network equipment to first terminal before the first channel type configured information is sent, be accomplished by judging whether the first terminal possesses interference deletion ability, can specifically be reported by first terminal indicate the first terminal whether have the interference of interference deletion ability delete ability label information or The identification information of the operating system for the first terminal that person reports according to first terminal judges that the identification information can be the version information of operating system.For example, when the operating system of first terminal is only to support

During LTE R1 1 version, judge that the first terminal does not have the ability for PDSCH signals disturb deletion action, when the operating system of first terminal is to support LTE R12 version, judge that the first terminal has the ability for PDSCH signals disturb deletion action.When disturbing the deletion ability label message identification first terminal to possess interference deletion ability, first network equipment sends the first characteristic of channel configured information to first terminal, or when first network equipment goes out the first terminal according to the identification information judgment of the operating system of first terminal and possesses interference deletion ability, the first characteristic of channel configured information is sent to first terminal.

Either, alternatively, before step 101, in addition to：

The interference puncturing pattern configuration information that the-network equipment is sent is received, interference puncturing pattern configuration information is used to configure first terminal into interference puncturing pattern.

First network equipment can be configured directly to first terminal, first terminal is set to enter interference puncturing pattern, the first characteristic of channel configured information that first network equipment is sent can be recognized, and respective handling is carried out according to first characteristic of channel configured information.In addition, it should be noted that, the step may be located on after the type indication information that first network equipment reports according to first terminal judges the first terminal without interference deletion ability, i.e. after first network equipment identifies first terminal without interference deletion ability, configuration information is issued to the first terminal and makes it have interference deletion ability.It specifically can according to actual needs be operated, will not be described here.

It is pointed out that other network equipments, i.e., the first network equipment that not first terminal belongs to, can also send the first characteristic of channel configured information to first terminal through the above way.It specifically can according to actual needs be set, will not be repeated here.
