Description

The present application claims priority to Chinese Patent Application No. 201410193509.2, entitled "A Control Information Transmission Method and Apparatus", filed on May 08, 2014, the entire contents of in.

Technical field

The present application relates to the field of communications technologies, and in particular, to a control information transmission method and device.

Background technique

The performance of a cellular network is typically limited by inter-cell and intra-cell interference. In a traditional cellular network, the terminal estimates the noise and covariance matrix of inter-cell interference, and suppresses inter-cell interference by receiving the shaped vector, such as Minimum Mean Square Error-Interference Rejection Combiner (MMSE-IRC). ) Receiver.

In recent years, as the processing power of the terminal is improved, it is possible to suppress and/or eliminate inter-cell interference by the terminal receiving algorithm, for example, introducing a symbol level interference canceling (SLIC) or a maximum likelihood receiver. Advanced receivers are used to suppress and/or eliminate interference between cells and cells to improve the demodulation performance of the target signal. At present, the receiving algorithm of the terminal using the advanced receiver may require a priori information related to the interference signal when performing interference signal suppression and/or cancellation, that is, the interference signal parameter needs to be configured in advance for the terminal. The interference signal parameters may be configured by the network and notified to the terminal through network signaling (such as high-level signaling), or the terminal may obtain the interference signal parameters by using a blind detection manner, or a combination of the foregoing two methods, that is, the network is The terminal configures the set of interference signal parameters, and then the terminal performs blind detection on the interference signal parameters in the set to determine the interference signal parameters received during data transmission.

The high-level signaling configuration interference signal parameter is a semi-static configuration mode. Once the terminal interference signal parameter is notified, the terminal will perform reception calculation according to the configured interference signal parameters for a relatively long period of time. Due to dynamic scheduling and frequency selective scheduling, the actual interfering signals are highly dynamic and may change every sub-frame. Therefore, using high-level signaling to configure interference signal parameters may impose restrictions on the scheduling of neighbors. If the interference signal parameters of the neighboring cell and the local cell are consistent with the interference signal parameters of the high layer signaling during the current data transmission, the performance of the receiving algorithm of the terminal is good, that is, the interference signal can be suppressed and/or eliminated, otherwise, the terminal The receiving algorithm reduces the reception performance of the terminal due to calculation based on the error interference signal parameters. In order to ensure the performance of the terminal using the advanced receiver, the neighboring area must transmit data to the interference signal parameters of the terminal according to the network configuration, but this will greatly limit the flexibility of scheduling, thereby causing network performance. decline.

In summary, the configuration of the existing interference signal parameters may limit the scheduling of the neighboring cell and the local cell, thereby reducing scheduling flexibility and causing degradation of network performance.

Based on any of the foregoing embodiments, the indication information carried in the DCI may be the bit information added in the DCI, or may be the existing bit information in the DCI (ie, multiplexing the existing bits in the DCI). Information as an indication).

Based on any of the foregoing embodiments, in step 12, the parameter information of the parameter information of the interference signal indicating the interference of the terminal to the current data transmission and the parameter information of the interference signal configured by the high layer signaling are indicated by the indication information carried in the DCI. The relationship between parameter values includes the following four preferred implementations:

Mode 1, by using the indication information, whether the parameter value of the parameter information of the interference signal indicating that the terminal interferes with the current data transmission is consistent with the parameter value of the configured parameter information.

1. The indication that the parameter value of the parameter information of the interference signal that causes the terminal to interfere with the current data transmission is consistent with the parameter value of the configured parameter information by using the indication information includes:

If it is determined that the parameter values of the parameter information of the interference signal causing interference to the current data transmission are the same as the parameter values of the configured same parameter information, the parameter indicating the interference signal of the terminal causing interference to the current data transmission by using the indication information The parameter value of the information is consistent with the parameter value of the configured parameter information;

Or, if it is determined that the parameter values of the parameter information of the interference signal that interferes with the current data transmission belong to the parameter value set of the configured same parameter information, the indication information is used to indicate that the terminal interferes with the current data transmission. The parameter value of the parameter information of the signal is consistent with the parameter value of the configured parameter information, wherein each configured parameter value set contains at least one parameter value.

Preferably, the parameter values in the different parameter value sets are partially different or all different.

In the embodiment of the present application, the parameter value of each parameter information of the interference signal that interferes with the current data transmission belongs to the configured parameter value set of the same parameter information, and refers to each of the interference signals that interfere with the current data transmission. Parameter information, the parameter value of the parameter information belongs to a set of parameter values of the configured parameter information.

For example, if the parameter information of two types of interference signals is configured, which are respectively the modulation mode and the transmission mode of the interference signal, the modulation mode of the interference signal that satisfies the determined interference to the current data transmission belongs to the configured modulation mode. Parameter value set, and the transmission mode of the interference signal causing interference to the current data transmission belongs to the parameter value set of the configured transmission mode, and the parameter value of the parameter information of the interference signal causing interference to the current data transmission and the configured parameter The parameter values of the information are consistent.

In this mode, when the terminal runs the reception detection algorithm, the interference suppression/cancellation is performed by using the parameter values of the appropriate parameter information according to the indication information of the DCI.

2. The indication that the parameter value of the parameter information of the interference signal that causes the terminal to interfere with the current data transmission is inconsistent with the parameter value of the configured parameter information by using the indication information includes:

If it is determined that the parameter value of the at least one parameter information of the interference signal that interferes with the current data transmission is different from the configured parameter value of the same parameter information, the indication information is used to indicate that the terminal interferes with the current data transmission. The parameter value of the parameter information of the interference signal is inconsistent with the parameter value of the configured parameter information (ie, indicating that the terminal should not make any assumptions about the value of various parameter information); or

If it is determined that the parameter value of the at least one parameter information of the interference signal that interferes with the current data transmission does not belong to the configured parameter value set of the same parameter information, the indication information is used to indicate that the terminal interferes with the current data transmission. The parameter value of the parameter information of the interference signal is inconsistent with the parameter value of the configured parameter information (ie, indicating that the terminal should not make any assumptions about the values of various parameter information), wherein each configured parameter value set includes at least A parameter value.

Preferably, the parameter values in the different parameter value sets are partially different or all different.

In this mode, when the terminal runs the receiving detection algorithm, the terminal should not use the configured parameter information for interference suppression/cancellation.

For example, the parameter value of the parameter information of the interference signal that causes the terminal to interfere with the current data transmission to be consistent with the parameter value of the configured parameter information may be used. If the bit information is “0”, the current data is indicated. The parameter value of the parameter information of the interference signal transmitting the interference is inconsistent with the parameter value of the parameter information of the configured interference signal; if the bit information is "1", the parameter parameter information indicating the interference signal causing interference to the current data transmission The value is consistent with the parameter value of the parameter information of the configured interference signal.

Manner 2: If a parameter information is configured for the terminal through the high layer signaling, step 12 is specifically:

1. If it is determined that the parameter value of the parameter information of the interference signal causing interference to the current data transmission is the same as one of the parameter values of the configured parameter information, the parameter indicating the parameter information that the terminal has configured is indicated by the indication information. Among the values, the parameter values of the same parameter information of the interference signal that interfere with the current data transmission are the same.

In this manner, the parameter value of the parameter information of the interference signal indicating that the terminal interferes with the current data transmission by using the indication information is which parameter value of the parameter information configured by the high layer signaling.

In this mode, when the receiving detection algorithm is run, the terminal performs interference suppression/cancellation according to the indication information of the DCI and the parameter value of the appropriate parameter information.

2. If it is determined that the parameter value of the parameter information of the interference signal that interferes with the current data transmission is different from any of the parameter values of the configured parameter information, the terminal is instructed to transmit the current data by using the indication information. The parameter value of the parameter information of the interference signal causing the interference is not the parameter value of the configured parameter information (ie, the terminal is not supposed to make any assumptions about the values of the various parameter information).

In this mode, when the terminal runs the receive detection algorithm, the terminal should not use the configured parameter information to perform interference suppression/cancellation.

For example, if the modulation mode of the interference signal configured for the terminal through the high layer signaling includes {QPSK, 16QAM}, the modulation mode of the interference signal that the terminal interferes with the current data transmission may be indicated by the 1-bit information in the DCI, such as “ 0′′ indicates that the modulation mode of the interference signal that interferes with the current data transmission is the configured QPSK modulation mode, and “1” indicates that the modulation mode of the interference signal that causes interference to the current data transmission is the configured 16QAM modulation mode; or, The 2-bit information in the DCI indicates the modulation mode of the interference signal that the terminal interferes with the current data transmission. For example, “00” indicates that the modulation mode of the interference signal that interferes with the current data transmission is not the configured modulation mode, and “01” indicates the pair. The modulation mode of the interference signal caused by the current data transmission is the configured QPSK modulation mode, and the “10” indicates that the modulation mode of the interference signal that causes interference to the current data transmission is the configured 16QAM modulation mode.

For another example, if the transmission mode of the network configuration terminal interference signal is {TM4, TM9}, the transmission mode of the interference signal needs to be indicated by 1 bit or 2 bits in the DCI.

For another example, if the cell identifier of the network configuration terminal interference signal includes {CELL-ID1, CELL-ID2} (a specific example, such as CELL-ID1=101, CELL-ID2=231), then 1 bit is needed in the DCI or 2 bits indicate the cell identity of the interference signal. The cell identity may determine a scrambling sequence of the interference signal, and the like.

For another example, if the possible values of the network configuration terminal interference signal P _A include {P _A1 , P _A2 } (a specific example, such as P _A1 =0 dB, P _A2 =−2 dB), then 1 bit is needed in the DCI or 2 bits indicate P _{A of the} interference signal.

Manner 3: If a parameter information is configured for the terminal by using the high layer signaling, step 12 is specifically:

1. If it is determined that the parameter value of the parameter information of the interference signal that causes interference to the current data transmission belongs to at least one parameter value set in the parameter value set of the configured parameter information, the indication information is used to indicate the parameter that the terminal has configured. The set of parameter values of the information includes a set of parameter values of parameter values of the parameter information of the interfering signals that interfere with the current data transmission; wherein each set of configured parameter values includes at least one parameter value.

Preferably, the parameter values in the different parameter value sets are partially different or all different.

In this manner, the network has configured a parameter value set of reference information of multiple interference signals for the terminal through high layer signaling. In the DCI, the terminal indicates that the parameter value of the reference information of the interference signal that interferes with the current PDSCH transmission belongs to which of the plurality of parameter value sets configured by the upper layer.

In this mode, when the terminal runs the reception detection algorithm, according to the indication information of the DCI, the terminal uses the parameter value set of the parameter information of the appropriate interference signal to perform interference suppression/cancellation.

2. If it is determined that the parameter value of the parameter information of the interference signal causing interference to the current data transmission does not belong to any parameter value set of the configured parameter information, the interference signal indicating that the terminal interferes with the current data transmission by using the indication information The parameter value of the parameter information is not the parameter value of the configured parameter information (ie, indicating that the terminal should not make any assumptions about the values of various parameter information); wherein each parameter value set contains at least one parameter value, and different parameter values The parameter values in the collection are partially or completely different.

In this mode, when the terminal runs the receiving detection algorithm, it should not use the configured parameter value set to perform interference suppression. System / elimination.

For example, if the modulation mode of the network configuration terminal interference signal includes {QPSK, 16QAM} and {16QAM, 64QAM}, the modulation mode of the interference signal indicating that the current data transmission is interfered by the 1-bit information in the DCI belongs to the configured mode. Which parameter value set is available. Or, the modulation mode of the interference signal that causes the terminal to interfere with the current data transmission through the 2-bit information in the DCI, for example, “00” indicates that the modulation mode of the interference signal that interferes with the current data transmission is not the parameter in any parameter set. Similarly, "01" indicates that the modulation mode of the interference signal that causes interference to the current data transmission belongs to the configured set {QPSK, 16QAM}, and "10" indicates that the modulation mode of the interference signal that causes interference to the current data transmission belongs to the configured set. {16QAM, 64QAM}.

For another example, if the transmission mode of the network configuration terminal interference signal is {TM4, TM7} and {TM8, TM9}, the transmission mode of the interference signal indicating that the terminal interferes with the current data transmission by 1 or 2 bits in the DCI can be indicated. Which set of parameter values is assigned to which one.

Mode 4: If at least two types of parameter information are configured for the terminal by using the high layer signaling, step 12 is specifically:

1. If it is determined that the parameter values of the parameter information of the interference signal causing interference to the current data transmission are respectively the parameter value sets of the same parameter information in the combination formed by the parameter value sets of the configured parameter information, the The indication information, the combination formed by the parameter value set indicating each parameter information that the terminal has configured, includes a combination of the parameter value sets to which the parameter values of the parameter information of the interference signal causing interference to the current data transmission respectively belong, wherein each The configured set of parameter values contains at least one parameter value.

Preferably, the parameter values contained in the different parameter value sets are partially different or all different.

Preferably, in the combination formed by the set of parameter values of the configured parameter information, each combination includes one parameter value set of each parameter information that is configured, and the parameter sets of at least one parameter information in different combinations are different.

In this manner, the network has configured, by the high layer signaling, a combination of a plurality of parameter value sets of each reference information including the interference signal for the terminal. The parameter value of each reference information of the interference signal that causes the terminal to interfere with the current PDSCH transmission in the DCI belongs to which of the plurality of combinations of the high layer configuration.

In this mode, when the terminal runs the reception detection algorithm, the interference suppression/cancellation is performed by using an appropriate combination according to the indication information of the DCI.

2. If it is determined that the parameter value of the at least one parameter information of the interference signal causing interference to the current data transmission does not belong to any parameter value set of the same parameter information in the combination formed by the parameter value set of each configured parameter information, then By using the indication information, the parameter value of the parameter information of the interference signal indicating that the terminal interferes with the current data transmission is not the parameter value of the configured parameter information (ie, indicating that the terminal should not make any assumptions about the values of the various parameter information); Each set of configured parameter values contains at least one parameter value.

Preferably, the parameter values contained in the different parameter value sets are partially different or all different.

In this mode, when the terminal runs the receiving detection algorithm, the terminal should not use the configured parameter information for interference suppression/cancellation.

For example, suppose that three types of parameter information are configured for the terminal through high-level signaling, which are respectively a modulation mode, a transmission mode, and a resource allocation type, and the configured parameter values include two combinations, and the combination of the first parameter value set is : modulation mode {QPSK, 16QAM}, transmission mode {TM4, TM7}, resource allocation type Type 0; combination of the second parameter set: modulation mode {16QAM, 64QAM}, transmission mode {TM8, TM9}, resource allocation Type 1; The parameter value of the parameter information of the interference signal indicating that the terminal interferes with the current data transmission by 1 bit in the DCI is the configured combination, as shown in Table 1.

Table 1;

DCI bit Modulation Transmission mode Resource allocation type 0 QPSK, 16QAM TM4, TM7 Type 0 1 16QAM, 64QAM TM8, TM9 Type 1

The parameter value of the parameter information of the interference signal that can indicate that the terminal interferes with the current data transmission through the 2 bits in the DCI is the configured combination, as shown in Table 2.

Table 2;

For example, it is assumed that three types of parameter information are configured for the terminal through high-level signaling, namely, cell identity, CFI, and system bandwidth. The configured parameter values include two combinations. The combination of the first parameter set is: cell identifier {CELL -ID1, CELL-ID2}, CFI{1,2}, system bandwidth 10MHz; the combination of the second parameter set is: cell identifier {CELL-ID3, CELL-ID4}, CFI{2,3}, system bandwidth 20MHz . Then, the parameter value of the parameter information of the interference signal indicating that the terminal interferes with the current data transmission through the 1-bit information in the DCI is the configured combination, as shown in Table 3.

Based on any of the foregoing embodiments, in step 22, according to the indication information carried in the DCI, the parameter value of the parameter information of the interference signal that interferes with the current data transmission and the parameter information of the interference signal that has been configured through the high layer signaling are determined. The relationship between parameter values includes the following four preferred implementations:

The first method corresponds to the above manner 1. Specifically:

According to the indication information carried in the DCI, it is determined whether the parameter value of the parameter information of the interference signal that interferes with the current data transmission is consistent with the parameter value of the configured parameter information.

In this manner, the method further includes:

If it is determined that the parameter value of the parameter information of the interference signal that interferes with the current data transmission is inconsistent with the parameter value of the configured parameter information, when the reception detection algorithm is executed, the interference suppression/cancellation is not performed based on the configured parameter information. .

Specifically, if it is determined that the parameter value of the parameter information of the interference signal that interferes with the current data transmission is consistent with the parameter value of the configured parameter information, when the reception detection algorithm is run, based on the parameter value of the configured parameter information, The advanced receiver algorithm is used for interference suppression/cancellation; if it is determined that the parameter value of the parameter information of the interference signal causing interference to the current data transmission is inconsistent with the parameter value of the configured parameter information, then when the reception detection algorithm is run, Interference suppression/cancellation should be performed using the configured parameter information. In this case, the traditional interference suppression/cancellation algorithm can be used for data demodulation (ie, traditional receiver algorithm), such as Minimum Mean Square Error (MMSE). Algorithms, etc., perform interference suppression/cancellation.

The second method corresponds to the above method 2. Specifically:

Determining, according to the indication information, a parameter value that is the same as a parameter value of the parameter information of the interference signal that interferes with the current data transmission among the parameter values of the configured parameter information;

Or, according to the indication information, determining that the parameter value of the parameter information of the interference signal that causes interference to the current data transmission is not the parameter value of the configured parameter information.

In this manner, the method provided by the present application further includes:

If it is determined that the parameter value of the parameter information of the configured parameter information is the same as the parameter value of the parameter information of the interference signal that interferes with the current data transmission, when the receiving detection algorithm is operated, the interference is caused based on the current data transmission. Interference suppression/cancellation of the parameter value of the parameter information of the interference signal;

If it is determined that the parameter value of the parameter information of the interference signal that interferes with the current data transmission is not the parameter value of the configured parameter information, when the reception detection algorithm is executed, the interference suppression/cancellation is not performed based on the configured parameter information.

The parameter value set to which the parameter value of the parameter information of the interference signal for transmitting interference belongs, uses an advanced receiver algorithm for interference suppression/cancellation; if it is determined that the parameter value of the parameter information of the interference signal that causes interference to the current data transmission is not The parameter value of the configured parameter information should not use the configured parameter information to perform interference suppression/cancellation when running the receiving detection algorithm. In this case, the traditional interference suppression/cancellation algorithm can be used for data demodulation (ie, traditional The receiver algorithm), such as the MMSE algorithm, performs interference suppression/cancellation.

It should be noted that, if the number of parameter values included in the parameter value set is two or more, the parameter value in the parameter value set is blindly checked when the reception detection algorithm is executed.
