detailed description

The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure. It is obvious that the described embodiments are a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

Referring to FIG. 1 , FIG. 1 is a structural diagram of a signal transmission system to which an embodiment of the present disclosure is applicable. As shown in FIG. 1 , the terminal 11 and the base station 12 are included, where the terminal may be a user equipment (User Equipment, UE) or Other terminal devices, such as mobile phones, tablet personal computers, laptop computers, personal digital assistants (PDAs), mobile Internet devices (MIDs), or wearable devices. A terminal device such as a device (Wearable Device), it should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present disclosure. The foregoing base station 12 may be a 5G base station (for example, gNB, 5G NR NB), or may be a 4G base station (for example, an eNB), or may be a 3G base station (for example, NB), etc., and it should be noted that, in the implementation of the present disclosure, The specific type of base station 12 is not limited in the example.

It should be noted that the specific functions of the foregoing terminal 11 and base station 12 will be specifically described by the following various embodiments.

Referring to FIG. 2, FIG. 2 is a flowchart of a signal transmission method according to an embodiment of the present disclosure. The method is applied to a terminal, as shown in FIG. 2, and includes the following steps:

Step 201: Receive a DCI sent by a base station.

The DCI may be scheduling information allocated by the base station for resources allocated by the terminal when the terminal transmits the uplink information, so that the terminal may perform transmission according to the DCI. The above-mentioned DCI may be DCI format 0_3 (DCI format 0_3) defined in the embodiment of the present disclosure. Of course, it is not limited thereto, and may also be DCI in other formats.

Step 202: Transmit physical resources by using the non-orthogonal multiple access data indicated by the DCI, and send an uplink signal to the base station.

The non-orthogonal multiple access data transmission physical resource can be understood as a physical resource that the terminal performs non-orthogonal transmission, for example, a physical resource block (PRB) that performs non-orthogonal transmission. In addition, the DCI may be indicated by information such as resource configuration information, identification, or serial number of the physical resource transmitted by the non-orthogonal multiple access data. And the non-orthogonal multiple access data transmission physical resource may be one or more non-orthogonal multiple access data transmission physical resources indicated by the DCI.

After receiving the DCI, the terminal may determine the non-orthogonal multiple access data transmission physical resource by using the information content in the DCI, and then send an uplink signal on the non-orthogonal multiple access data transmission physical resource, thereby implementing non-orthogonality. The uplink data transmission in the multiple access mode can increase the number of terminals simultaneously accessed, improve the access capability of the communication system, and provide a large number of terminal accesses, thereby improving the performance of the communication system.

It should be noted that, in the embodiment of the present disclosure, the foregoing method may be applied to the terminal shown in FIG. 1. In addition, in the implementation of the present disclosure, it can be applied to a 5G system, and can also be applied to an LTE system and a multi-carrier applied to a code division multiple access (CDMA) technology for uplink transmission, and is applied in this scenario. The above method can improve the number of terminals that are simultaneously accessed, improve the access capability of the communication system, and provide a large number of terminal accesses, thereby improving the performance of the communication system.

The embodiment of the present disclosure can implement uplink data transmission in the non-orthogonal multiple access mode by transmitting an uplink signal to the base station on the non-orthogonal multiple-address data transmission physical resource, and improve the terminal accessing the terminal at the same time. Quantity, and the performance of the communication system.

Referring to FIG. 3, FIG. 3 is a flowchart of another signal transmission method according to an embodiment of the present disclosure. The method is applied to a terminal. As shown in FIG. 3, the method includes the following steps:

Step 301: Receive a DCI sent by a base station, where the DCI is used to indicate a multiple access signature (MA signature).

Of course, the above-mentioned MA signature can also be translated into a multiple access identifier. That is to say, in the embodiment of the present disclosure, the multiple access identifier may also be referred to as a multiple access identifier.

Step 302: Use a non-orthogonal multiple access data corresponding to the multiple access identifier indicated by the DCI to transmit a physical resource, and send an uplink signal to the base station.

Step 301 and step 302, it is possible to configure a corresponding multiple access identifier for each non-orthogonal multiple access data transmission physical resource, for example, each non-orthogonal multiple access data transmission physical resource corresponds to one multiple access The identifier is added, so that only the above-mentioned multiple access identifier needs to be indicated in the DCI, that is, resource allocation for non-orthogonal transmission of the terminal can be implemented, thereby reducing the signaling overhead of the DCI, and further implementing the control signaling overhead based on extremely low. There are scheduled non-orthogonal multiple access uplink transmissions.

As an optional implementation manner, the DCI includes multiple access identifier allocation information, where the multiple access identifier allocation information is used to indicate one or more multiple access identifiers, and different multiple access identifiers. Have different serial numbers.

In this implementation manner, the non-orthogonal multiple access data transmission physical resource corresponding to one or more multiple access identifiers may be allocated to the terminal by using the multiple access identifier allocation information, and in addition, due to different multiple access identifiers Having different sequence numbers, such that the multiple access identifier allocation information only needs to carry the sequence number of one or more multiple access identifiers, that is, resource allocation for non-orthogonal transmission of the terminal can be implemented, thereby reducing DCI signaling. The overhead, in turn, enables scheduled non-orthogonal multiple access uplink transmission with very low control signaling overhead.

Optionally, when the multiple access identifier allocation information is used to indicate a multiple access identifier, the multiple access identifier allocation information includes a sequence number of the multiple access identifier indicated by the multiple access identifier;

In this embodiment, the multiple access identifier allocation information directly carries the sequence number of the multiple access identifier corresponding to the allocated non-orthogonal multiple access data transmission physical resource, so that the terminal can quickly and directly determine the assigned non-positive Multi-address data is transmitted to transmit physical resources, thereby improving transmission efficiency.

For example, if only one multiple access identification resource can be used for each non-orthogonal multiple access uplink transmission, the multiple access identification allocation information only needs to indicate the serial number of the multiple access identification. If the physical resource pool of the non-orthogonal multiple access transmission configured for the terminal by the configuration signaling corresponds to N multiple access identifiers, the information domain needs log ₂ (N) bits of information. If N=8, the information indicated by the different bit values of the information field is as shown in Table 1:

Table 1. Instructions for multiple access identification assignment information

Optionally, when the multiple access identifier allocation information is used to indicate multiple multiple access identifiers, the multiple access identifier allocation information includes an identifier number and an identifier sequence number, where the number of identifiers is The number of multiple access identifiers indicated by the multiple access identifier allocation information, where the identifier sequence number is one of multiple multiple access identifiers indicated by the multiple access identifier assignment information The serial number of the multiple access identifier, and the serial numbers of the multiple multiple access identifiers indicated by the multiple access identifier allocation information are consecutive.

The identifier number may be a sequence number of a multiple access identifier of a specific location preset, for example, a sequence number of the first multiple access identifier of the multiple multiple access identifiers, or multiple multiple accesses. The serial number of the multiple access identifier of the end of the identifier, or the serial number of the intermediate multiple access identifier of the plurality of multiple access identifiers, and the like.

Preferably, the identifier sequence number is a sequence number of the first multiple access identifier in the plurality of multiple access identifiers indicated by the multiple access identifier allocation information, and the initial multiple access identifier is Derefering a multiple access identifier with the smallest serial number among the plurality of multiple access identifiers;

or,

The identifier sequence number is a sequence number of the end multiple access identifier in the plurality of multiple access identifiers indicated by the multiple access identifier allocation information, and the ending multiple access identifier is the multiple multiple access identifiers The multiple access identifier with the highest sequence number in the access identifier.

In this embodiment, since only the identification sequence number and the number of identifiers are indicated, the signaling overhead can be reduced.

It should be noted that, in the embodiment of the present disclosure, the non-orthogonal multiple access data transmission physical resource may also be referred to as a multiple signature access resource (MA signature resource), because the non-orthogonal multiple access data transmission physical resource and multiple access The access identifier corresponds.

In this implementation manner, the non-orthogonal multiple access uplink transmission can use multiple MA signature resources, that is, the non-orthogonal multiple corresponding to multiple multiple access identifiers is used. Address data transfer physical resources. The multiple access identification assignment information needs to indicate the sequence number of all the multiple access identifiers used for the transmission. If the sequence numbers of the multiple access identifiers used by the uplink transmission are consecutive, the multiple access identifier allocation information may indicate the sequence numbers of the multiple multiple access identifiers through two sub-information fields, for example: one child The information field indicates the sequence number of the initial multiple access identification resource, and the other sub-information field is used to indicate the number of multiple access identification resources used for transmission (or the number of multiple access identification identifiers). As shown in table 2:

Table 2. Instructions for multiple access identification assignment information

Optionally, the multiple access identifier allocation information is used to indicate multiple multiple access identifiers by using a bitmap structure.

In this embodiment, if one or more multiple access identification resources can be used for each non-orthogonal multiple access uplink transmission, the multiple access identification allocation information may indicate all multiple accesses used for the transmission. Identifies the serial number of the resource. If the uplink transmission can use any number of multiple access identification resources, the multiple access identification assignment information can be bitmapped to indicate the multiple access identification resources employed. If there are N multiple access identifiers in the physical resource pool of non-orthogonal multiple access transmission (or may be referred to as a non-orthogonal multiple access data transmission physical resource set) configured by the configuration signaling for the terminal, the information domain needs N bits of information. Wherein, if the kth bit is 1, it indicates that the kth multiple access identification resource is used in the current transmission. If the kth bit is 0, it indicates that the kth multiple access identification resource is not transmitted this time. As shown in FIG. 4, FIG. 4 shows bit bitmap information of the multiple access identification allocation information when the first, second, and sixth multiple access identification resources are selected when N=8.

In the present embodiment, since the indication is performed by the bitmap method, the signaling overhead can be reduced.

As an optional implementation manner, the DCI includes a transmission parameter, where the transmission parameter includes at least one of the following:

New data indication, modulation scheme, coding rate, redundancy version, and power control configuration;

The new data indication is used to indicate to transmit new data or retransmit data.

It should be noted that, in the embodiment of the present disclosure, the new data may be understood as the initial data transmitted by the terminal, that is, the data is data that the terminal does not transmit.

The modulation mode and the coding rate are used to indicate a modulation mode and a coding rate used for transmitting new data. The power control configuration is used to indicate uplink power control, for example, a Transmitting power control (TPC) command.

In this implementation manner, the sequence number indicating the multiple access identifier in the DCI and the foregoing transmission parameter may be implemented, thereby avoiding excessive signaling transmission to save transmission resources.

The sending the uplink signal to the base station may include:

And transmitting an uplink signal to the base station according to the transmission parameter.

That is, the terminal performs transmission according to the transmission parameter indicated by the DCI, for example, using the modulation mode, the coding rate, the redundancy version, and the power control configuration indicated by the DCI.

Preferably, the DCI is DCI format 0_3 as an example, as shown in Table 3:

Table 3. DCI format 0_3 table of contents

It should be noted that, if the non-orthogonal multiple-address data transmission physical resource is pre-configured with a modulation mode, a coding rate, and a redundancy version, the modulation mode, the coding rate, and the redundancy version may not be configured in the foregoing transmission parameter. The orthogonal multiple access data transmission physical resource is not configured with a modulation mode, a coding rate, and a redundancy version, and the modulation mode, the coding rate, and the redundancy version may be configured in the foregoing transmission parameters.

It can be seen from the foregoing Table 1 that the DCI needs to indicate the frequency resource, the time resource, and whether the frequency hopping is used or the like, and the present embodiment can reduce the overhead of the control signaling, thereby improving the efficiency of system transmission.

In the above embodiment, the multiple access identifier allocation information used to indicate the sequence number of the multiple access identifier may be understood as: the multiple access access identifier resource allocation content in Table 1 is related to indicating the multiple access identifier resource. Information to implement a sequence number indicating one or more multiple access identities.

It should be noted that, in this embodiment, in addition to the resource allocation of the non-orthogonal transmission by using the indication multiple access identifier, the DCI can implement resource allocation of the non-orthogonal transmission by other means, for example, the above DCI. It is also possible to indicate the frequency information of the physical resources of the terminal non-orthogonal transmission, or the number of the PRB, and the like. In addition, the DCI described above includes an implementation of the transmission parameters, and can be applied to the embodiment shown in FIG. 2, and the same beneficial effects can be achieved, and are not described herein.

As an optional implementation manner, the non-orthogonal multiple-address data transmission physical resource corresponding to the multiple access identifier indicated by the DCI is used to send an uplink signal to the base station, including:

Determining, according to the multiple access identifier indicated by the DCI, a non-orthogonal multiple access data transmission physical resource corresponding to the multiple access identifier from a pre-configured non-orthogonal multiple access data transmission physical resource set;

Transmitting physical resources to the base station by using the non-orthogonal multiple access data to transmit uplink signals

The foregoing pre-configured non-orthogonal multiple access data transmission physical resource set may be configured before performing step 301. In addition, in this embodiment, the non-orthogonal multiple access data transmission physical resource set may also be referred to as a physical resource library of the non-orthogonal multiple access transmission of the foregoing terminal.

In this embodiment, uplink data transmission in the non-orthogonal multiple access mode may be implemented, and in addition, the non-orthogonal multiple access data transmission physical resource set configured by the terminal for non-orthogonal transmission is configured in advance, thereby performing non-orthogonal transmission. During the resource allocation process, the base station only needs to indicate the sequence number or other indication information of the non-orthogonal multiple access data transmission physical resource used by the terminal, thereby reducing the signaling overhead.

Optionally, each non-orthogonal multiple access data transmission physical resource in the non-orthogonal multiple access data transmission physical resource set is configured with a corresponding multiple access identifier, and each multiple access identifier is configured with a corresponding Resource configuration information.

Each non-orthogonal multiple access data transmission physical resource in the non-orthogonal multiple access data transmission physical resource set is configured with a corresponding non-orthogonal access identifier, and each non-orthogonal access identifier in the physical resource set may be The multiple access data transmission physical resource may correspond to a multiple access identifier (MA signature). Each of the non-orthogonal access identifiers is configured with a corresponding resource configuration. Each of the multiple access identifiers is configured with resource configuration information used on the corresponding orthogonal multiple access data transmission physical resource. For example, each multiple access identifier corresponds to a specific frequency resource, and corresponding resource configuration information used on the frequency resource, for example, a spreading code, a pattern, and a power. In addition, a certain De Modulation Reference Signal (DMRS) and modulation information can be configured.

In this embodiment, each non-orthogonal multiple access data transmission physical resource is configured with a corresponding multiple access identifier, and each multiple access identifier is configured with corresponding resource configuration information, so that during the transmission process, The base station only needs to indicate the multiple access identifier corresponding to the non-orthogonal multiple access data transmission physical resource used by the terminal, and the terminal can directly transmit according to the resource configuration information corresponding to the multiple access identifier, that is, in the transmission process. The base station does not need to indicate resource configuration information in the DCI, thereby saving signaling overhead.

Optionally, before receiving the DCI sent by the base station, the method further includes:

Receiving configuration signaling sent by the base station, where the configuration signaling is used to configure the non-orthogonal multiple access data transmission physical resource set.

The configuration signaling may be Radio Resource Control (RRC) signaling. Of course, it is not limited, and may be other signaling, for example, broadcast signaling.

In this implementation manner, the non-orthogonal multiple-access data transmission physical resources of the terminal, that is, the non-orthogonal multiple access of the user, may be implemented before the terminal performs non-orthogonal transmission. The physical resource library of the transfer. The configuration is performed by configuring signaling, so that the configuration can be flexibly configured to implement matching between the non-orthogonal multiple-access data transmission physical resources configured by the terminal and the service of the terminal, thereby improving the transmission performance of the communication system. Of course, in this embodiment, the non-orthogonal multiple-address data transmission physical resource set may be configured in other manners, for example, pre-defined in the protocol, and the like.

Optionally, the configuration signaling includes: a frequency resource information, a resource configuration information, and a sequence number of the multiple access identifier, where the frequency resource information is used to indicate a frequency resource corresponding to the multiple access identifier;

Is a frequency resource. The resource configuration information may be related configuration information of the frequency resource. In addition, in the foregoing configuration signaling, corresponding frequency resource information and resource configuration information corresponding to each multiple access identifier may be configured for each multiple access identifier. Of course, in some scenarios, multiple multiple access identifiers may be corresponding to the same resource configuration information, which is not limited.

Optionally, the resource configuration information includes at least one of the following:

Spreading code or sparse code allowed;

Allowable power;

In this implementation manner, the spreading code, the sparse code, the power, the pattern, the DMRS, the DMRS antenna port, the modulation mode, the coding rate, and the redundancy version may be pre-configured through configuration signaling, so that in the non-orthogonal transmission process, the base station There is no need to configure this information for the terminal, which in turn can reduce the signaling overhead of the DCI of the signal transmission process.

Further, the foregoing resource configuration information may further include: a modulation mode, a coding rate, and a redundancy version.

In this way, since the modulation mode, the coding rate, and the redundancy version can be pre-configured, the signaling overhead of the DCI of the signal transmission process can be reduced.

It should be noted that the implementation may be implemented in combination with the implementation of the DCI indication transmission parameter in the embodiment, where the resource configuration and the foregoing transmission parameter may be non-intersecting, for example, the resource configuration includes a modulation mode, For the coding rate and redundancy version, the above transmission parameters may not include the modulation mode, the coding rate, and the redundancy version. When transmitting the signal, the terminal may transmit according to the foregoing resource configuration information and the foregoing transmission parameter, for example, using a spreading code, a sparse code, a power, a pattern, a DMRS, a DMRS antenna port, a modulation mode, and a coding rate in the resource configuration information. And one or more of these redundancy versions, and the uplink signal transmission in combination with the power control configuration in the above transmission parameters.

The transmitting the uplink signal to the base station according to the frequency resource information and the resource configuration information may be: using the frequency resource information of the frequency resource information corresponding to the multiple access identifier indicated by the DCI, and according to the multiple access Identifying corresponding resource configuration information, and sending an uplink signal to the base station.

Further, in the present embodiment, resource configurations such as different DMRS or DMRS antenna ports can be arranged for different waveforms. For example, the configuration signaling is used as the RRC signaling, and the configuration signaling can be as shown in Table 4:

Table 4. RRC Configuration Information Field Content Table for Multiple Access Identification

The resource block allocation information may be understood as the frequency resource information. The sequence number of the multiple access identifier in the non-orthogonal multiple access data transmission physical resource set, the corresponding frequency resource information, and the corresponding resource configuration information are flexibly configured by using the foregoing table content.

In the foregoing implementation manner, the frequency resource information and the resource configuration information may be pre-configured through configuration signaling, so that in the non-orthogonal transmission process, the base station does not need to configure the information for the terminal, thereby reducing the signaling of the DCI of the signal transmission process.
