The first terminal and the second terminal include, but are not limited to, a mobile station (MS), a mobile terminal (Mobile Terminal), a mobile telephone (Mobile Telephone), a mobile phone (handset), and a portable device (ortable equipment), etc., the first The terminal can communicate with one or more core networks via a Radio Access Network (RAN). For example, the user equipment can be a mobile phone (or "cellular" phone), a computer with wireless communication function, and the like. The user device can also be a portable, pocket, handheld, computer built-in or in-vehicle mobile device.

The first channel characteristic indication information is used to indicate that the first terminal demodulates the interference signal by using a specific channel characteristic, that is, the interference signal is demodulated by using the first channel characteristic in this embodiment. The first channel characteristic indication information may directly carry related information of the first channel characteristic, or instruct the first terminal to select a required first channel characteristic from among a plurality of channel characteristics sent by the first network device to the first terminal. Etc., can be set according to actual needs. The first channel characteristic in this embodiment includes at least one of the following: delay spread of the channel experienced by the signal, Doppler spread of the channel, Doppler shift of the channel (Doppler Shift), the average gain of the channel, the average delay of the channel (Average delay)

Step 102: Demodulate the received signal according to the first channel characteristic.

Among them, the signal includes an interference signal and a useful signal. The first terminal demodulates the received signal according to the first channel characteristic, and specifically, the first terminal performs coherent demodulation on the received signal according to the first characteristic to delete the interference signal, that is, demodulate the interference from the signal. After the signal, delete it. How to perform demodulation according to channel characteristics belongs to the prior art and will not be described herein.

A useful signal is a signal that needs to be received by the first terminal, such as a PDSCH (Physical Downlink Shared Channel) signal or an EPDCCH (Enhanced Physical Downlink Control) designed in a Long-Term Evolution (LTE) system. Channel, Enhanced Physical Downlink Control Channel) signal, which can be used to transmit data or signaling. An interfering signal is a signal that interferes with a useful signal.

It should be noted that the first terminal may first delete the interference signal according to the first channel characteristic, and then demodulate the useful signal, and the first terminal may simultaneously perform the operation of deleting the interference signal and demodulating the useful signal, or the first terminal. Multiple Input Multiple Output (MIMO) or Multiple-User Multiple Input Multiple Output (MU-MIMO) combined reception for interference signals and useful signals. In this embodiment, the order of execution of demodulation of the interference signal and demodulation of the useful signal is not limited, and may be specifically set according to actual needs.

According to the method of wireless signal processing of the present embodiment, the first terminal performs the interference deletion operation by acquiring the first channel characteristic corresponding to the interference signal, so that the interference signal is deleted more thoroughly, and finally the demodulation performance of the useful signal is ensured, that is, both Demodulation of interference signals and useful signals

This embodiment provides a method for wireless signal processing based on Embodiment 1.

In this embodiment, step 101 is specifically illustrated. Specifically, step 101 of any one of the following manners may be implemented. Mode A: receiving the channel characteristic indication information sent by the first network device to which the first terminal belongs, where the first channel characteristic indication information includes the first channel characteristic of the interference signal sent by the at least one second network device or the at least one second terminal The first channel characteristic of the transmitted interference signal, the first terminal determines the first channel characteristic of the interference signal according to the first channel characteristic indication information.

In actual applications, other network devices may cause significant interference to the first terminal. As shown in FIG. 2A, when the first network device 210 and the second network device 211 simultaneously send signals to the first terminal 212 and the second terminal 213, respectively, the signal sent by the first network device 210 is related to the second network device 211. The signal sent to the second terminal 213; ^ interference. In addition, other terminals may also cause significant interference to the first terminal. As shown in FIG. 2B, at a certain point in time, the first network device 220 sends a downlink signal to the first terminal 222, and the second terminal 223 sends an i-line signal to the second network device 221. If the first terminal 222 and the first terminal When the communication of the second terminal 223 is small, the uplink signal sent by the second terminal 223 may cause significant interference to the downlink signal sent by the first network device 220 received by the first terminal 222.

In this embodiment, the second terminal is different from the first terminal, and the manner of determining the second terminal is not limited. For example, the terminal may be a terminal whose absolute value of the channel fading of the first terminal is less than a preset threshold, and the preset threshold may be based on actual conditions. Need to set. For example, the first terminal measures, according to the indication of the first network device to which the first terminal belongs, the RS sent by the first network device and the RS sent by the second terminal, where the first network device may send only the second terminal. The information of the RS is used to notify the first terminal, including the time information, the frequency information, and the like of the second terminal, and further, the identifier information of the second terminal is notified to the first terminal, and the reference signal receiving power corresponding to the two RSs is reported ( The reference network Received Power (RSRP), the first network device can compare the difference between the two RSRPs. When the value of the difference is lower than the preset threshold, the second terminal is considered to be obvious to the first terminal. The first network device instructs the first terminal to measure a certain RS. When the RSRP corresponding to the RS is higher than a certain threshold, the first terminal sends a message to the first network device, reporting that the RS is the first. The first network device determines that the source corresponding to the RS (ie, the second terminal) causes significant interference to the first terminal according to the information.

It should be noted that the “home” in the first network device to which the first terminal belongs according to the embodiment indicates that the first network device can send signaling, data, or receive signaling sent by the first terminal to the first terminal. The operation of the data, that is, the first terminal can communicate with the first network device, and does not indicate that the first terminal is set in the first network device.

Mode B: receiving, according to the first channel characteristic indication information, among the multiple channel characteristics acquired in advance, selecting the first terminal and the first terminal The first channel characteristic of the corresponding interfering signal.

The plurality of channel characteristics may be sent to the first terminal in advance by the first network device, and may be sent by using the semi-static signaling, or may be obtained by the first terminal measuring the RS. Then, the first network device may select to send the first channel characteristic indication information to the first terminal by using dynamic signaling. The first terminal selects a first channel characteristic of the interference signal from the plurality of channel characteristics according to the first channel characteristic indication information.

In the prior art, signaling includes semi-static signaling and dynamic signaling. Before the first terminal receives the new semi-static signaling, the first terminal always uses the information indicated by the semi-static signaling, such as RRC (Radio Resource Control) signaling. Dynamic signaling is characterized in that one dynamic signaling only corresponds to a limited one or more transmissions, such as PDCCH (Physical Downlink Control Channel) signaling. The first network device first uses the semi-static signaling to send the channel characteristic with a large amount of information to the first terminal, and then uses the dynamic signaling with less information to indicate that the first terminal uses one of the channel characteristics, thereby reducing the signaling overhead. Reduce the burden on the network.

The first channel characteristic indication information in mode B may be a bit, a number, a letter, or a combination of numbers and letters. The first terminal can learn the specific content represented by the first channel characteristic indication information according to the preset rule. For example, when the first channel characteristic indication information is 1, it may indicate that the first channel characteristic is selected as the interference channel by using the first channel characteristic among the plurality of channel characteristics. The pre-special need to specify that the ordering of multiple channel characteristics may be determined by bit position information of each channel characteristic, or a set of channel characteristics may be preset in advance, and may be set according to actual needs. I will not repeat them here.

The mode C: receiving the first channel characteristic indication information sent by the first network device to which the first terminal belongs, where the first channel characteristic indication information is used to indicate that the first terminal uses the same channel characteristic demodulation signal as the useful signal;

The first channel characteristic of the interference signal is determined to be the same channel characteristic as the useful signal based on the first channel characteristic indication information.

In a system using Multiple-User Multiple Input Multiple Output (MU-MIMO) technology, the interference signal can also come from the same network device as the wanted signal, and interference signals may occur at this time. First channel characteristics and useful signals The case where the second channel characteristics are the same. In this case, the first terminal can extract the second channel characteristic of the useful signal to demodulate the interference signal and delete the interference signal.

Mode D: receiving, by the first network device, the first channel characteristic indication information that is sent by the first terminal, and selecting, according to the first channel characteristic indication information, the interference signal from the plurality of channel characteristics acquired by the first terminal by measuring the RS First channel characteristics.

The first terminal can obtain the channel characteristics by measuring the RS signal, and can obtain multiple channel characteristics through one RS, or obtain a channel characteristic through one RS, that is, obtain multiple channel characteristics by measuring multiple RSs. How to obtain channel characteristics by measuring RS belongs to the prior art and will not be mentioned here. The first channel characteristic indication information in the mode D may be a bit, a number, a letter or a combination of a number and a letter. According to a preset rule, the first terminal may know which is a channel characteristic corresponding to the first channel characteristic indication information. For example, when the first characteristic indication information is 1, it indicates that the channel characteristic obtained by measuring the first RS is used as the channel characteristic.

It should be noted that the measurement RS is measured by the configuration information line of the RS for measurement, and the configuration information of the RS for measurement includes one or more of the following information: frequency information of the RS, time information of the RS, RS power information, RS sequence information, RS message, RS antenna port information, etc.

And receiving: the first channel characteristic indication information sent by the first network device to which the first terminal belongs; determining, according to the first channel characteristic indication information, the configuration information of the plurality of pre-acquired RSs for measuring Quasi co-location information;

The first channel characteristic of the interference signal is determined according to the quasi co-location information of the interference signal.

The first channel characteristic indication information may be sent by using dynamic signaling, and the configuration information of multiple RSs for measurement may be sent by using semi-static signaling. The quasi-co-location information of the present embodiment indicates that the signal and the certain CSI-RS are both from the same network device, and therefore the channels of the signals are the same, that is, the quasi-co-location of the signals, so that the UE can measure the CSI-RS according to the CSI-RS. The determined channel characteristics and the signal are processed. In the embodiment of the present invention, the quasi-co-location information of the interference signal indicates that the interference signal has the same channel characteristics as a certain CSI-RS, so that the UE can facilitate the UE according to the CSI-RS. The determined channel characteristics are measured to process the interfering signals.

The first channel characteristic indication information may be a number, a letter, or a combination of numbers and letters. For example, as shown in Table 1, two signaling bits are used to indicate which RS is co-located with the interference signal. It is assumed that the first terminal receives four RSs, which are the first RS, the second RS, the third RS, and the fourth RS, respectively, and the correspondence between the first channel characteristic indication information and the content thereof is as shown in Table 1.

Table 1 First channel characteristic indication information indicating content

00 interference signal and first RS quasi-co-location

01 Interference signal and second RS quasi-co-location

10 interference signal and third RS quasi-co-location

11 The interference signal and the first RS, the second RS, the third RS, and the fourth RS in the first RS quasi-co-location table 1 are actually a group of RSs respectively, and the group RS^—the network device transmits the same at several moments. An RS of a characteristic, such as a plurality of RSs having the same period and time offset, occupying the same time-frequency resource, and/or using the same sequence, corresponding to the same configuration information, in the embodiment of the present invention, each group having the same characteristics The same RS is regarded as the same RS. The following is the same as the RS of the embodiment of the present invention, which can represent the RSs with the same characteristics sent by the same network device at several moments. That is, the first network device sends configuration information of the RS for measurement to the first terminal, and the first terminal periodically measures the corresponding RS according to the configuration information of the RS for measurement to obtain channel characteristics, and the specific operation is bribe technology. I don't want to talk about it here.

The multiple RSs having the same period and time offset may be, for example, a transmission time interval of 5 ΤΉ and a time offset of 1 ,, and may be specifically numbered 1, 6 , 11... ΤΉ It can be set according to actual needs, for example, 1 millisecond. The first terminal obtains the quasi-co-location information ^ of the interference signal according to Table 1, and can acquire the first channel characteristic of the interference signal according to the quasi-co-location information.

The first channel characteristic indication information may also be 1 bit, as shown in Table 2.

Table 2

It can be seen from 2 that the first channel characteristic of the interference signal may be the same as the useful signal, because in the system using the MU-MIMO technology, the interference signal can also come from the same network device as the useful signal. At the time, the first channel characteristic of the interference signal is the same as the second channel characteristic of the useful signal.

In addition, the first channel characteristic indication information may not only indicate which RS signal is common to the interference signal. The address can also represent the mapping mode information of the interference signal.

For example, as shown in FIG. 3A and FIG. 3B, FIG. 3A is a schematic diagram of mapping manner information of an uplink DM RS and a data signal, and mapping manner information of a downlink DM RS and a data signal, that is, FIG. 3A is an uplink DM RS and data for demodulation. FIG. 3B is a schematic diagram of mapping mode information of a downlink DM RS and a data signal used for demodulation. FIG. The data signal in this embodiment is a useful signal. At this time, the first channel characteristic indication information may use a 2-bit signaling field, as shown in Table 3. This facilitates flexible indication to the first terminal that the interference signal is an uplink interference signal or a downlink interference signal, and reduces signaling overhead. The specific first terminal is obtained from the prior art according to the information of the demodulated DM RS and the data signal.

Optionally, the configuration information of the multiple RSs for measurement included in the foregoing manner includes at least one configuration information of the uplink RS for measurement.

The method of wireless signal processing corresponding to this method is particularly suitable for flexible duplex (Flexible

In a communication system, a transmitting device, a receiving device or a duplex transmitting device, a receiving device, or a receiving device, which are involved in time-varying different adaptations of traffic adaptation, interference adaptation, resource adaptation, etc. Or the receiving device can change the allocation of the uplink resource or the downlink resource correspondingly according to the change of the service, the interference situation, the resource utilization, and the like, where the uplink resource or the downlink resource includes the time and/or the frequency resource.

Mode F: Before step 101, the first terminal first receives the first network to which the first terminal belongs. The configuration information of the DM RS for demodulation sent by the network device and the mapping mode information of the useful signal, and the second channel characteristic of the useful signal is obtained according to the mapping mode information.

The configuration information of the DM RS for demodulation and the mapping mode information of the useful signal, and the first channel characteristic indication information may be respectively sent in different signaling. In the method F, the first network device first goes to the first terminal. The configuration information of the DM RS for demodulation and the mapping mode information of the useful signal are sent, so that the first terminal acquires the second channel characteristic of the useful signal. In this manner, the first channel characteristic indication information that is sent by the first network device that the first terminal belongs to in step 101 includes: receiving, by the first network device that the first terminal belongs, the first channel characteristic indication information, the first channel characteristic The indication information is used to indicate that the first channel characteristic and the second channel characteristic are the same.

The second channel characteristic here is the channel characteristic of the useful signal. The mapping mode information in the mode F is used to indicate that the first terminal uses the mapping information of the configuration information of the uplink DMRS for demodulation and the useful signal, or uses the configuration information and the useful signal of the downlink DM RS for demodulation. Mapping mode information. In this way, the first terminal can use the second channel characteristic to demodulate the signal to acquire the interference signal and delete the interference signal.

Manner G: receiving configuration information of the DM RS for demodulation sent by the first network device and mapping mode information of the interference signal, and acquiring the first channel characteristic of the interference signal according to the mapping mode information.

In the mode G, the first channel characteristic indication information sent by the first network device includes mapping information of the configuration information of the DM RS for demodulation and the interference signal, and the interference signal can acquire the interference according to the mapping mode information. The first channel characteristic of the signal.

Optionally, in this embodiment, before step 101, the method further includes:

Sending the type indication information of the first terminal to the first network device, so that the first network device determines, according to the type indication information, whether to send the first channel characteristic indication information to the first terminal, where the type indication information is used to indicate whether the first terminal can identify The first channel characteristic indicates information. Specifically, the type indication information may include interference deletion capability identification information of the first terminal or identification information of an operating system of the first terminal.

The first network device may determine whether the first terminal has interference cancellation capability before sending the first channel type indication information to the first terminal, because the first terminal may not have the interference cancellation (interference cancellation) capability. Specifically, the interference deletion capability identification information that is reported by the first terminal, indicating whether the first terminal has interference cancellation capability, or The device determines that the identifier information is the version information of the operating system according to the identifier information of the operating system of the first terminal reported by the first terminal. For example, when the operating system of the first terminal is only supported

When the version of LTE R1 1 is used, it is determined that the first terminal does not have the capability of performing an interference deletion operation on the PDSCH signal. When the operating system of the first terminal is a version supporting LTE R12, it is determined that the first terminal has a PDSCH signal. The ability to perform interference removal operations. The first network device sends the first channel characteristic indication information to the first terminal, or the first network device determines, according to the identifier information of the operating system of the first terminal, when the interference cancellation capability identifier information indicates that the first terminal has the interference deletion capability. When the first terminal has the interference cancellation capability, the first channel characteristic indication information is sent to the first terminal.

Alternatively, optionally, before step 101, the method further includes:

The interference deletion mode configuration information sent by the first network device is received, and the interference deletion mode configuration information is used to configure the first terminal to enter the interference deletion mode.

The first network device can directly configure the first terminal to enable the first terminal to enter the interference deletion mode, that is, can identify the first channel characteristic indication information sent by the first network device, and perform corresponding processing according to the first channel characteristic indication information. . In addition, it should be noted that the step may be performed after the first network device determines that the first terminal does not have the interference deletion capability according to the type indication information reported by the first terminal, that is, when the first network device identifies that the first terminal does not After the interference cancellation capability is performed, the configuration information is sent to the first terminal to have interference cancellation capability. The operation can be performed according to actual needs, and will not be described here.

It should be noted that the other network device, that is, the first network device that is not the first terminal, may also send the first channel characteristic indication information to the first terminal in the foregoing manner. The settings can be made according to actual needs, and will not be described here.

In an actual application, the method for determining the first channel characteristic of the interference signal by using the first terminal in the embodiment may be used according to an actual situation, and the interference deletion operation is performed according to the first channel characteristic, so that the interference signal is deleted more. In addition, before the first network device sends the first channel characteristic indication information, the first network device may determine whether the interference cancellation capability is performed by using the type indication information reported by the first terminal, or directly configure the first terminal to enter the interference. The deletion mode prevents the first terminal from transmitting the first channel characteristic indication information to the first terminal.

Embodiment 3 This embodiment further supplements the method of wireless signal processing of the above embodiment. That is, in the above embodiment, the first network device may send the channel characteristic indication information of the useful signal to the first terminal, so that the first terminal acquires the second channel characteristic of the useful signal according to the channel characteristic indication information.

The specific manner may be any one or more of the following ways:

Method a: receiving second channel characteristic indication information of the useful signal sent by the first network device, and determining a second channel characteristic of the useful signal according to the second channel characteristic indication information;

The signal is demodulated according to the second channel characteristic to obtain a useful signal.

The second channel characteristic indication information may be a combination of a bit, a number, a letter, or a combination of a number and a letter. The specific implementation is similar to the first channel characteristic indication information, and details are not described herein.

The second channel characteristic indication information is different from the first channel characteristic indication information, that is, the first network device sends two channel characteristic indication information to the first terminal, where the first channel characteristic indication information is used to indicate that the first terminal acquires The first channel characteristic of the interference signal, the second channel characteristic indication information is used to indicate that the first terminal acquires the second channel characteristic of the useful signal.

Specifically, the second channel characteristic indication information may include a second channel characteristic of the useful signal directly, or may be a manner of indicating how the first terminal acquires the second channel characteristic. For example, how the first terminal obtains the second channel characteristic of the useful signal according to the second channel characteristic indication information, and the first network device may send multiple channel characteristics to the first terminal in advance, and may specifically send the semi-static signaling, It may be that the first terminal measures the RS to acquire a plurality of channel characteristics. Then, the first network device can select to send the second channel characteristic indication information to the first terminal by using dynamic signaling. The first terminal selects a second channel characteristic of the useful signal from the plurality of channel characteristics according to the second channel characteristic indication information. There are many other ways for the first terminal to acquire the second channel characteristic, and details are not described herein again.

In the prior art, signaling includes semi-static signaling and dynamic signaling. Before the first terminal receives the new semi-static signaling, the first terminal will always use the information indicated by the semi-static signaling, such as RRC signaling. Dynamic signaling is characterized in that one dynamic signaling only corresponds to a limited one or more transmissions, such as PDCCH signaling. The first network device first uses the semi-static signaling to send the channel characteristic with a large amount of information to the first terminal, and then uses the dynamic signaling with less information to indicate that the first terminal uses one of the channel characteristics, thereby reducing the signaling overhead. Reduce the burden on the network.

The second channel characteristic indication information may be a group of bits, numbers, letters or numbers and letters Hehe. The first terminal may learn the specific content represented by the first channel characteristic indication information according to the preset rule. For example, when the second channel characteristic indication information is 1, it may indicate that the second channel characteristic is selected as the interference signal by selecting the first channel characteristic among the plurality of channel characteristics. The preset rule can be stored in each network device or each terminal in a list manner.

It should be specially noted that the ordering of the channel characteristics may be determined by the bit position information of each channel characteristic, or the order of a set of channel characteristics may be preset, which may be set according to actual needs, and is no longer Narration.

The sending operation or the receiving operation of the first network device may be the direct behavior of the first network device, or the first network device may control the sending operation or the receiving operation indirectly through the device connected to the wired or wireless manner. The first terminal and the second terminal include but are not limited to a mobile station, a mobile terminal, a mobile phone, a mobile phone, a portable device, etc., and the first terminal can communicate with one or more core networks via a radio access network, for example, a user equipment It can be a mobile phone (or "cellular" phone), a computer with wireless communication capabilities, etc., and the user device can also be a portable, pocket, handheld, computer built-in or in-vehicle mobile device.

Step 402: Send first channel characteristic indication information to the first terminal, so that the first terminal determines the first channel characteristic of the interference signal according to the first channel characteristic indication information, and demodulates the received signal according to the first channel characteristic. . Among them, the signal includes an interference signal and a useful signal.

The first channel characteristic indication information is used to indicate that the first terminal demodulates the interference signal by using a specific channel characteristic, that is, the interference signal is demodulated by using the first channel characteristic in the embodiment. The first channel characteristic indication information may directly carry related information of the first channel characteristic, or instruct the first terminal to select a required first channel characteristic from among a plurality of channel characteristics sent by the first network device to the first terminal. Etc., can be set according to actual needs.

The first channel characteristic in this embodiment includes at least one of the following: delay spread of the channel experienced by the signal, Doppler spread of the channel, Doppler shift of the channel (Doppler Shift), the average gain of the channel, the average delay of the channel (Average delay)

The first terminal specifically determines the first channel characteristic of the interference signal according to the first channel characteristic indication information, and how to demodulate the received signal according to the first channel characteristic. For details, refer to the description in the first embodiment to the third embodiment. I will not repeat them here. It should be noted that the first terminal may first delete the interference signal according to the first channel characteristic, and then demodulate the useful signal, and the first terminal may simultaneously perform the operation of deleting the interference signal and demodulating the useful signal. In this embodiment, the execution sequence of the demodulation of the interference signal and the demodulation of the useful signal is not limited, and specifically Set according to actual needs.

It is conceivable that the first channel characteristic indication information may include both the first channel characteristic of the interference signal and the second channel characteristic of the useful signal.

Embodiment 5

This embodiment is further described in detail based on the method of wireless signal processing in the fourth embodiment. In the embodiment, the manner in which the first network device indicates that the first channel characteristic indication information is sent is mainly described.

Method H: acquiring a first channel characteristic of an interference signal sent by at least one second network device that causes interference to the first terminal that belongs to the first network device, and generating first channel characteristic indication information, the first channel characteristic indication information The first channel characteristic of the interference signal transmitted by each second network device is included; or

And selecting, according to the measurement report reported by the first terminal, the at least one second terminal that causes interference to the first terminal, acquiring the first channel characteristic of the interference signal sent by the second terminal, and generating the first channel characteristic indication information, the first channel The characteristic indication information includes the first channel characteristic of the interference signal transmitted by each second terminal.

This mode H only further explains step 401. Specifically, the first network device may obtain the first channel characteristic of the interference signal sent by each second network device by using the central control node, or select the second terminal by using the measurement report reported by the first terminal. In the mode H, the first channel characteristic is directly added to the first channel characteristic indication information, so that when the first terminal receives the first channel characteristic indication information, the first channel characteristic can be directly obtained, and the received signal is received. Demodulation is performed, that is, the interference signal is demodulated, and the interference signal is deleted.

In this embodiment, the second terminal is different from the first terminal, for example, the terminal with the absolute value of the channel fading of the first terminal is less than a preset threshold, and the preset threshold may be set according to actual needs. For example, the first terminal, according to the indication of the first network device to which the first terminal belongs, measures the RS sent by the first network device and the RS sent by the second terminal (the RS sent by the second terminal does not need to be notified first) The terminal network), and reporting the reference signal received power (RSRP) corresponding to the two RSs, the first network device can compare the difference between the two RSRPs, when the value of the difference is lower than the ^^ value When the threshold is preset, the second terminal is considered to have significant interference to the first terminal; or the first terminal measures an RS, and when the RSRP corresponding to the RS is lower than a certain threshold, the first terminal is first The network device sends a message, and reports that the source corresponding to the RS (ie, the second terminal) causes significant interference to the first terminal.

Method I: This method I further describes step 402.

Before the first channel characteristic indication information is sent to the first terminal, the method further includes:

Sending a multi-word feature to the first terminal;

Transmitting the first channel characteristic indication information to the first terminal, so that the first terminal determines, according to the first channel characteristic indication information, the first channel characteristic of the interference signal, including:

The first channel characteristic indication information is sent to the first terminal, so that the first terminal selects a channel feature of the interference signal corresponding to the first terminal among the plurality of channel characteristics acquired in advance according to the first channel characteristic indication information.

The first network device may obtain multiple channel characteristics through the central control node, and then send multiple channel characteristics to the first terminal, and then generate first channel characteristic indication information, where the first channel characteristic indication information is used to indicate that the first terminal is in Among the plurality of channel characteristics acquired in advance, the first channel characteristic of the interference signal corresponding to the first terminal is selected.

For example, when the first channel characteristic indication information is 1, it may indicate that the first channel characteristic is selected as the interference channel by using the first channel characteristic among the plurality of channel characteristics. The preset rule can be stored in each network device or each terminal in a list manner.

It should be specially noted that the ordering of the channel characteristics may be determined by the bit position information of each channel characteristic, or the order of a set of channel characteristics may be preset, which may be set according to actual needs, and is no longer Narration. In the method I, the manner of the first terminal is the same as the mode B, and is not mentioned here.

In the prior art, signaling includes semi-static signaling and dynamic signaling. Before the first terminal receives the new semi-static signaling, the first terminal always uses the information indicated by the semi-static signaling, such as signaling. Dynamic signaling is characterized in that a single dynamic signal corresponds to only a limited one or more transmissions, such as PDCCH signaling. The first network device first uses the semi-static signaling to send the channel characteristic with a large amount of information to the first terminal, and then uses the dynamic signaling with less information to indicate that the first terminal uses one of the channel characteristics, thereby reducing the signaling overhead.

Transmitting, by the first terminal, first channel characteristic indication information, so that the first terminal is configured according to the first channel The sexual indication information selects the first channel characteristic of the interference signal from the first terminal by measuring the multiple characteristics of the RS.

In this mode K, step 402 is further explained. The first network device first sends configuration information of multiple RSs for measurement to the terminal, and the terminal uses the configuration information of the RS for measurement to measure the RS to obtain channel characteristics. The first terminal can obtain the channel characteristics by measuring the RS signal, and can obtain multiple channel characteristics through one RS, or obtain a channel characteristic through one RS, that is, obtain multiple channel characteristics by measuring multiple RSs. How to obtain the channel characteristics by measuring the RS is specific to the prior art and will not be mentioned here. At this time, the first channel characteristic indication information indicates that the first terminal selects the first channel characteristic of the interference signal from the plurality of channel characteristics of the first terminal by measuring the RS. The specific implementation manner of the first-sentence indication information and the implementation and manner of the first terminal D are not mentioned here.

It should be noted that the configuration information of the RS for measurement of the mode K and the mode L may include at least one configuration information of the uplink RS for measurement.

Mode N: Before sending the first channel characteristic indication information to the first terminal, the method further includes: sending, to the first terminal, mapping information of the configuration information of the RS for demodulation and the useful signal, so that the first terminal according to the mapping manner The information acquires a second channel characteristic of the useful signal.

In the mode N, the first channel characteristic indication information is specifically used to indicate that the first channel characteristic and the second channel characteristic are the same.

The mapping mode information in the mode N may be as shown in FIG. 3A or FIG. 3B. The first terminal acquires the corresponding second channel characteristic according to the configuration information of the RS for measurement and the mapping mode information of the useful signal, and then receives the identifier. a first channel having the same channel characteristics as the second channel characteristics When the characteristic indication information is used, the second channel characteristic is used to demodulate the interference signal, and the interference signal is deleted.

The first network device may determine whether the first terminal has interference cancellation capability before sending the first channel type indication information to the first terminal, because the first terminal may not have the interference cancellation (interference cancellation) capability. The information may be determined by the first terminal to indicate whether the first terminal has the interference deletion capability identification information of the interference cancellation capability or the identifier information of the operating system of the first terminal. The identifier information may be version information of the operating system. For example, when the operating system of the first terminal is a version supporting LTE R11, the first network device determines that the first terminal does not have the capability of performing an interference deletion operation on the PDSCH signal, and the operating system of the first terminal supports the LTE R12. The first network device determines that the first terminal has the capability of performing an interference delete operation on the PDSCH signal.
