Referring to fig. 1, an embodiment of the present invention provides a reference signal transmission processing method, as shown in fig. 1, the method includes the following steps:

step 101, sending first indication information to a user equipment, where the first indication information is used to indicate reference signal set information, and the reference signal set information includes at least one of a first reference signal and a second reference signal, where the first reference signal and the second reference signal are multiplexed on a time-frequency resource.

The reference signal transmission processing method provided by the embodiment of the invention is mainly applied to network side equipment and used for controlling the sending of the reference signal.

Specifically, the sending of the reference signal includes a first sending scenario sent by the network side device to the user terminal, and a second sending scenario sent by the user terminal to the network side device. In this embodiment, for the processing of the reference signal in the first transmission scenario, the network side device notifies the user terminal of the reference signal to be sent through the first indication information. The reference signal set information may only include the first reference signal, may only include the second reference signal, and may also include both the first reference signal and the second reference signal. When the reference signal set information includes the first reference signal and the second reference signal at the same time, that is, the second reference signal is used as the first reference signal, at this time, the user terminal receiving the first indication information may demodulate the first reference signal and the second reference signal at the same time according to the second reference signal sent by the network side.

After receiving the first indication information, the ue may demodulate at least one of the first reference signal and the second reference signal according to the indicated reference signal set information. In this embodiment, the multiplexing manner of the first reference signal and the second reference signal on the time-frequency resource may be set according to actual needs, and for different multiplexing manners and different types of reference signals included in the reference signal set information, reference signals that the user terminal may demodulate are also different, which is described in detail in the following embodiments.

In this way, in the embodiment of the present invention, first indication information is sent to a user equipment, where the first indication information is used to indicate reference signal set information, and the reference signal set information includes at least one of a first reference signal and a second reference signal, where the first reference signal and the second reference signal are multiplexed on a time-frequency resource. Since the first reference signal and the second reference signal are configured to be multiplexed, the first reference signal does not need to be configured separately, and therefore, the system overhead of the reference signal is reduced.

It should be noted that the types of the first Reference signal and the second Reference signal may be set according to actual needs, for example, in this embodiment, the first Reference signal is one of a channel State Information Reference signal CSI-rs (channel State Information Reference signal), a downlink tracking Reference signal trs (time Reference signal), or a demodulation Reference signal dmrs (demodulation Reference signal) of a downlink shared physical channel. The second reference signal is one of a demodulation reference signal DMRS of a synchronization signal block SS-block, a demodulation reference signal DMRS of a downlink shared physical channel, a channel state information reference signal CSI-RS or a downlink tracking reference signal TRS. Specifically, when the second reference signal is CSI-RS or TRS, the second reference signal may be transmitted periodically or aperiodically, and is not limited herein.

In the network side device, the first reference signal and the second reference signal may be transmitted simultaneously or may not be transmitted simultaneously, which is not further limited herein.

Further, the number of physical Resource blocks PRB (physical Resource block) occupied by the second reference signal may be less than or equal to the number of PRBs occupied by the multiplexing reference information, or may be greater than the number of PRBs occupied by the multiplexing reference information. The multiplexing of the first reference signal and the second reference signal on the time-frequency resource may be different for different states, which is described in detail below:

in an embodiment, when the number of PRBs occupied by the second reference signal is less than or equal to the number of PRBs occupied by the multiplexing reference information, the multiplexing manner of the first reference signal and the second reference signal on the time-frequency resource may include: and taking the second reference signal as the first reference signal, or the first reference signal is orthogonal or quasi-orthogonal to the second reference signal.

Specifically, when the first reference signal is orthogonal or quasi-orthogonal to the second reference signal, the first reference signal includes a base sequence or a primitive polynomial that uses the same as the second reference signal.

In another embodiment, when the number of PRBs occupied by the second reference signal is greater than the number of PRBs occupied by the multiplexing reference information, the first reference signal includes a first partial reference signal and a second partial reference signal, wherein the occupied physical resource blocks PRB of the first partial reference signal coincide with the PRBs occupied by the second reference signal, and the generation method of the first partial reference signal is the same as the generation method of the second reference signal, and the second partial reference signal is generated by one generation method or at least two generation methods, wherein,

when the second partial reference signal is generated by a generation method, the generation method of the second partial reference signal is the same as or different from the generation method of the second reference signal; and

when the second partial reference signal is generated by the at least two generation methods, one of the at least two generation methods is the same as the generation method of the second reference signal or both of the at least two generation methods are different from the generation method of the second reference signal.

In this embodiment, the first partial reference signal is a reference signal in which all PRBs occupied by the first reference signal and the second reference signal are overlapped. The generation method of the second part of reference signals beyond the PRB occupied by the second reference signal may be one, or may be multiple. Each generation method can generate one reference signal block, a plurality of reference signal blocks can be combined in sequence to form a second part of reference signals, and the first reference signals are synthesized by the first part of reference signals and the second part of reference signals. In this embodiment, the first partial reference signal may be the same as the second reference signal or the first partial reference signal may be orthogonal or quasi-orthogonal to the second reference signal.

Further, the ue needs to demodulate the reference signal, and the ue needs to obtain the resource used by the reference signal and the corresponding resource location. In this embodiment, the first indication information is further used to indicate resources and resource locations used by the first reference signal and/or the second reference signal.

For better understanding of the present invention, the DMRS with the second reference signal SS-block is taken as an example, and the following is described in detail:

in the first case: and the network side equipment configures the SS-block DMRS and generates a second reference signal according to the configured SS-block DMRS. And then, sending the first indication information to the specified user terminal, wherein the first indication information is used for indicating the first reference signal and the second reference signal, and comprises the resource used by the second reference signal, the sequence generation mode, the resource position and the like. So that the user terminal receiving the first indication information can demodulate the first reference signal and the second reference signal.

In the second case: and the network side equipment generates a first reference signal according to the SS-block DMRS generating method. And then, sending the first indication information to the specified user terminal, wherein the first indication information is used for indicating the first reference signal and comprises the resource used by the first reference signal, the sequence generation mode, the resource position and the like. So that the user terminal receiving the first indication information can demodulate the first reference signal.

In the third case: when the number of PRBs occupied by the first reference signal is greater than the number of PRBs occupied by the SS-block DMRS, that is, when the bandwidth in which the first reference signal needs to be configured is greater than the bandwidth of the DMRS, the first reference signal may be configured to be obtained by one or more generation methods. Specifically, the bandwidth overlapping portion of the first reference signal and the DMRS (i.e., the first partial reference signal) may be configured to be obtained according to the DMRS generation method; the second reference signals of the excess portion (i.e., the second reference signals of the above portion) may be obtained by additionally configuring one or more generation methods, where one of the one or more additionally configured methods may be the same as the generation method of the DMRS, or all of the additionally configured generation methods may be different from the generation method of the DMRS.

Further, referring to fig. 2, an embodiment of the present invention further provides a reference signal processing method, as shown in fig. 2, the method includes:

step 201, sending second indication information to the user terminal, where the second indication information is used to indicate the user terminal to configure and generate at least one of a first reference signal and a second reference signal;

step 202, receiving and demodulating at least one of a first reference signal and a second reference signal sent by the user equipment, wherein the first reference signal and the second reference signal are multiplexed on a time-frequency resource.

Specifically, the sending of the reference signal includes a first sending scenario sent by the network side device to the user terminal, and a second sending scenario sent by the user terminal to the network side device. In this embodiment, for the processing of the reference signal in the second sending scenario, the network side device notifies the user terminal to configure and generate the reference signal through the second indication information, and sends the reference signal on the specified time-frequency resource. The network side device may demodulate at least one of the first reference signal and the second reference signal sent by the user terminal. The user terminal may transmit the first reference signal and the second reference signal separately, or may transmit the first reference signal and the second reference signal simultaneously. When the first reference signal and the second reference signal are simultaneously transmitted, that is, the second reference signal is used as the first reference signal, at this time, the network side device may simultaneously demodulate the first reference signal and the second reference signal for the second reference signal transmitted by the user terminal receiving the first indication information.

In this embodiment, the multiplexing manner of the first reference signal and the second reference signal on the time-frequency resource may be set according to actual needs, and for different multiplexing manners and different types of reference signals included in the reference signal set information, reference signals that the user terminal may demodulate are also different, which is described in detail in the following embodiments.

In this way, in the embodiment of the present invention, second indication information is sent to the user terminal, where the second indication information is used to indicate that the user terminal configures to generate at least one of the first reference signal and the second reference signal; and receiving at least one of a first reference signal and a second reference signal sent by the user equipment, wherein the first reference signal and the second reference signal are multiplexed on time-frequency resources. Since the first reference signal and the second reference signal are configured to be multiplexed, the first reference signal does not need to be configured separately, and therefore, the system overhead of the reference signal is reduced.

It should be noted that the types of the first Reference signal and the second Reference signal may be set according to actual needs, for example, in this embodiment, the first Reference signal is a channel sounding Reference signal srs (sounding Reference signal); the second reference signal is a demodulation reference signal DMRS of the uplink shared physical channel. Specifically, when the second reference signal is the SRS, the second reference signal may be transmitted periodically or aperiodically, and is not limited herein.

when the second partial reference signal is generated by a generation method, the generation method of the second partial reference signal is the same as or different from the generation method of the second reference signal;

Further, the network side device that the user equipment needs to transmit the reference signal also needs to configure the resource and the resource location used by the reference signal. In this embodiment, the second indication information is further used to indicate a resource and a resource location used by the ue to configure and generate the first reference signal and/or the second reference signal.

For better understanding of the present invention, the second reference signal is taken as an SRS for example, and the following is described in detail:

in the first case: the network side device configures the relevant information for generating the first reference signal in the second indication information of the first reference signal of the user terminal, and at this time, the second indication information may directly indicate that the second reference signal is sent as the first reference signal (that is, the second indication information indicates the first reference signal and the second reference signal). At this time, the user terminal generates an SRS according to the information on the SRS and transmits the SRS. And the network side equipment demodulates the SRS according to the received SRS, and demodulates the first reference signal according to the received SRS.

In the second case: the network side equipment configures relevant information for generating the first reference signal in second indication information of the first reference signal of the user terminal, at the moment, the second indication information indicates that the generation mode of the first reference signal is the generation mode of the SRS, the user terminal generates and transmits the first reference signal according to the generation mode of the SRS, the first reference signal is orthogonal or quasi-orthogonal to the SRS, and the first reference signal comprises a base sequence or a primitive polynomial which is the same as the SRS. The network side device may receive and demodulate the first reference signal.

In the third case: when the number of PRBs occupied by the first reference signal is greater than the number of PRBs occupied by the SRS, that is, when the bandwidth in which the second reference signal needs to be configured is greater than the bandwidth of the SRS, the first reference signal may be configured to be obtained by one or more generation methods, and specifically, a portion where the bandwidth of the first reference signal coincides with the bandwidth of the SRS (that is, the first partial reference signal) may be configured to be obtained according to the SRS generation method; the second reference signal beyond the part (i.e., the second partial reference signal) may be obtained by additionally configuring one or more generation methods, wherein one generation method of the additionally configured one or more generation methods may be the same as the SRS generation method, or all the generation methods of the additionally configured additional reference signals may be different from the SRS generation method.

Further, referring to fig. 3, an embodiment of the present invention further provides a reference signal transmission processing method, as shown in fig. 3, the method includes:

step 301, receiving first indication information sent by a network side device, where the first indication information is used to indicate reference signal set information, and the reference signal set information includes at least one of a first reference signal and a second reference signal;

step 302, receiving the first reference signal and/or the second reference signal sent by the network side device, and demodulating the first reference signal and/or the second reference signal according to the first indication information, where the first reference signal and the second reference signal are multiplexed on a time-frequency resource.

The reference signal transmission processing method provided by the embodiment of the invention is mainly applied to the user terminal and is used for controlling the receiving and demodulation of the reference signal.

In this way, in the embodiment of the present invention, first indication information sent by a network side device is received, where the first indication information is used to indicate reference signal set information, and the reference signal set information includes at least one of a first reference signal and a second reference signal; and receiving the first reference signal and/or the second reference signal sent by the network side device, and demodulating the first reference signal and/or the second reference signal according to the first indication information, wherein the first reference signal and the second reference signal are multiplexed on a time-frequency resource, and a first reference signal and a second reference signal are configured for multiplexing, so that a first reference signal does not need to be configured separately, and thus, the system overhead of the reference signal is reduced.

It should be noted that the types of the first reference signal and the second reference signal may be set according to actual needs, for example, in this embodiment, the first reference signal is one of a channel state information reference signal CSI-RS, a downlink tracking reference signal TRS, or a demodulation reference signal DMRS of a downlink shared physical channel. The second reference signal is one of a demodulation reference signal DMRS of a synchronization signal block SS-block, a demodulation reference signal DMRS of a downlink shared physical channel, a channel state information reference signal CSI-RS or a downlink tracking reference signal TRS. Specifically, when the second reference signal is CSI-RS or TRS, the second reference signal may be transmitted periodically or aperiodically, and is not limited herein.

In the network side device, the first reference signal and the second reference signal may be transmitted simultaneously or may be transmitted at different times, which is not further limited herein.

Further, referring to fig. 4, an embodiment of the present invention further provides a reference signal processing method, as shown in fig. 4, the method includes:

step 401, receiving second indication information sent by a network side device, where the second indication information is used to indicate a user equipment to configure and generate at least one of a first reference signal and a second reference signal;

step 402, generating and sending at least one of the first reference signal and the second reference signal according to the second indication information, wherein the first reference signal and the second reference signal are multiplexed on a time-frequency resource.

In this way, in the embodiment of the present invention, second indication information sent by a network side device is received, where the second indication information is used to indicate that a user terminal configures to generate at least one of a first reference signal and a second reference signal; and generating and sending at least one of the first reference signal and the second reference signal according to the second indication information, wherein the first reference signal and the second reference signal are multiplexed on time-frequency resources. Since the first reference signal and the second reference signal are configured to be multiplexed, the first reference signal does not need to be configured separately, and therefore, the system overhead of the reference signal is reduced.

It should be noted that the types of the first reference signal and the second reference signal may be set according to actual needs, for example, in this embodiment, the first reference signal is a channel sounding reference signal SRS; the second reference signal is a demodulation reference signal DMRS of the uplink shared physical channel. Specifically, when the second reference signal is the SRS, the second reference signal may be transmitted periodically or aperiodically, and is not limited herein.

For better understanding of the implementation of the present invention, a specific form of multiplexing the first reference signal and the second reference signal is described below, as shown in fig. 5, and a detailed description is given below for different multiplexing situations.

The first reference signal 501 is one of a channel state information reference signal CSI-RS, a downlink tracking reference signal TRS, or a demodulation reference signal DMRS of a downlink shared physical channel. The second reference signal 502 is one of a demodulation reference signal DMRS of a synchronization signal block SS-block, a demodulation reference signal DMRS of a downlink shared physical channel, a channel state information reference signal CSI-RS, or a downlink tracking reference signal TRS. For example, the first reference signal is a CSI-RS and the second reference signal is a SS-block DMRS; the first reference signal is a CSI-RS, and the second reference signal is PDSCH DMRS; the first reference signal is PDSCH DMRS and the second reference signal is a CSI-RS or a TRS.

In one example, the start position of the frequency domain between the second reference signal 502 and the first reference signal 501 may be offset, as shown.

The third case is the multiplexing state shown in c of fig. 5, in which the bandwidth of the first reference signal 501 is greater than the bandwidth of the second reference signal, wherein the solid-line box represents the first reference signal 501 and the dashed-line box represents the second reference signal 502. Specifically, the first reference signal 501 includes a first part of reference signal 5011 coinciding with the PRB occupied by the second reference signal 502 and a second part of reference signal 5012 exceeding the first part, wherein the first part of reference signal 5011 is generated by the same method as the second reference signal 502, and the second part of reference signal 5012 may include one or more generation methods. When the second partial reference signal 5012 is generated by one generation method, the generation method of the second partial reference signal 5012 is the same as or different from that of the second reference signal 502; when the second partial reference signal 5012 is generated by at least two generation methods, there is one generation method among the at least two generation methods that is the same as the generation method of the second reference signal 502 or all the generation methods are different from the generation method of the second reference signal 502.
