For example, the access network device sends RRC specific information to the terminal. The RRC-specific information may be terminal-level parameters (or called UE-level parameters), and parameter configuration is performed for the terminal.

For the configuration method of RRC-specific information, a single terminal can be configured with sidelink resources. In a specific implementation, the access network device can send RRC-specific information to a single terminal. The RRC-specific information is used to configure sidelink resources for the terminal . Since the RRC-specific information is sent to a single terminal, the side-link resources configured by the RRC-specific information can be used for unicast transmission between the terminals in the group. For example, the terminal 1 can use the side-link resources configured by the RRC-specific information to The terminal 2 unicast sends data or control information.

Of course, in practical applications, the sidelink resources configured by the RRC specific information can also be used for broadcast transmission and / or multicast transmission, which is not limited in this application.

V. Transmission type

In this application, transmission types may include unicast, multicast, and broadcast. Among them, unicast (unicast) may refer to communication between one terminal and another terminal. Multicast (groupcast) can refer to the communication between a terminal and a group of terminals. Broadcast (broadcast) may refer to the communication between a terminal and multiple terminals. Optionally, broadcast may refer to communication between one terminal and all terminals in the cell, or understood as communication between one terminal and multiple groups of terminals.

As shown in FIG. 2, this is a method for configuring sidelink resources provided by the present application. The method includes the following steps:

Step 201: The first terminal receives first configuration information of the sidelink resource sent by the network device. The sidelink resource configured by the first configuration information includes a first sidelink bandwidth part BWP resource, and the first sidelink BWP resource includes The side link sends BWP resources and / or the side link receives BWP resources.

In an implementation manner, the network device is an operator's network management system, and the first configuration information may be pre-configuration information, and the first configuration information is used by the terminal to determine the side link resource. For example, the first configuration information may include information on one or more sidelink resources, or the first configuration information is used to indicate one or more sidelink resources. After receiving the first configuration information, the first terminal may determine The first configuration information includes or indicates one or more sidelink resources. The sidelink resources configured by the first configuration information include a first sidelink BWP resource, and the first sidelink BWP resource may include a sidelink sending BWP resource and / or a sidelink receiving BWP resource. It should be noted that, in this implementation manner, the first terminal may be any terminal under the coverage of the base station or outside the coverage of the base station, that is, the terminal under the coverage of the base station or outside the coverage of the base station may be referred to as the first terminal, or understood as, Terminals under the coverage of the base station or outside the base station can configure the sidelink resources through the first configuration information. Of course, the terminals under the coverage of the base station or outside the base station can also be referred to as second terminals. For example, when only one terminal is mentioned, the terminal can be called the first terminal, and when two terminals are mentioned, one terminal can be called the first terminal and the other terminal can be called the second terminal to distinguish it. . Therefore, the terminals under or under the coverage of the base station can communicate using the first side-link BWP resource configured by the first configuration information, where the communication may include sending control information and / or data, and the communication may include receiving Control information and / or data. For example, the communication between the first terminal and the second terminal includes: the first terminal may send control information and / or data to the second terminal, and / or, the first terminal may receive the control information and / or data sent by the second terminal Wait. It can be understood that the first sidelink BWP resource configured by the network management system through the preconfiguration information can support broadcast transmission, or it can be understood that it can support sidelink communication whose transmission type is broadcast, or can be understood as a sideband that can support broadcast services. Link communication. Of course, the first sidelink BWP resource configured by the network management system through the pre-configuration information can also support multicast and / or unicast, or it can be understood that it can also support a sidechain with a transmission type of multicast and / or a transmission type of unicast Road communication, or it can be understood that it can also support side-link communication of multicast services and / or unicast services.

In yet another implementation manner, the network device is an access network device, and the first configuration information may be system information or RRC public information. The first configuration information is used by the terminal to determine the sidelink resource. For example, the first configuration information may include information on one or more sidelink resources, or the first configuration information is used to indicate one or more sidelink resources. After receiving the first configuration information, the first terminal may determine The first configuration information includes or indicates one or more sidelink resources. The sidelink resources configured by the first configuration information include a first sidelink BWP resource, and the first sidelink BWP resource may include a sidelink sending BWP resource and / or a sidelink receiving BWP resource. It should be noted that in this implementation, the first terminal may be any terminal in a group of terminals covered by a base station, that is, any terminal in a group of terminals covered by a base station may be called a first terminal, or understood as For any terminal in a group of terminals covered by the base station, the side link resources can be configured through the first configuration information. Of course, any terminal in the group covered by the base station can also be called a second terminal. For example, when only one terminal is mentioned, any terminal in the group may be referred to as the first terminal, and when two terminals in the group are mentioned, one terminal may be referred to as the first terminal for distinction , Another terminal is called a second terminal. Therefore, any two terminals in a group covered by the base station can communicate using the first side-link BWP resource configured by the first configuration information. The communication here may include sending control information and / or data, and the communication may This includes receiving control information and / or data. For example, the communication between the first terminal and the second terminal includes: the first terminal sends control information and / or data to the second terminal, and includes the second terminal receiving control information and / or data sent by the first terminal. It can be understood that the first sidelink BWP resource configured by the access network device through system information configuration or RRC common information can support multicast, or it can be understood that it can support sidelink communication whose transmission type is multicast, or understand In order to support the side-link communication of the multicast service. Of course, the first sidelink BWP resource configured by the access network device through system information configuration or RRC common information can also support unicast and / or broadcast, or it can be understood that the transmission type can also support unicast and / or transmission type Broadcast sidelink communication, or it can be understood that unicast services and / or sidelink communication of broadcast services can also be supported.

In yet another implementation manner, the network device is an access network device, and the first configuration information may be RRC-specific information, and the first configuration information is used by the terminal to determine the sidelink resource. For example, the first configuration information may include information on one or more sidelink resources, or the first configuration information is used to indicate one or more sidelink resources. After receiving the first configuration information, the first terminal may determine The first configuration information includes or indicates one or more sidelink resources. The sidelink resources configured by the first configuration information include a first sidelink BWP resource, and the first sidelink BWP resource may include a sidelink sending BWP resource and / or a sidelink receiving BWP resource. It should be noted that, in this implementation, the first terminal may be any terminal covered by the base station, that is, any terminal covered by the base station may be referred to as the first terminal, or understood as any terminal covered by the base station The configuration of the sidelink resources is performed through the above first configuration information. Of course, any terminal covered by the base station may also be called a second terminal. For example, when only one terminal is mentioned, any terminal covered by the base station may be referred to as the first terminal, and when two terminals covered by the base station are referred to, one terminal may be referred to as the first terminal for distinction. The other terminal is called a second terminal. Therefore, when any two terminals under the coverage of the base station are configured with the first sidelink BWP resource, then the two side terminals can communicate using the first sidelink BWP resource configured by the first configuration information. Communication may include sending control information and / or data, and communication may include receiving control information and / or data. For example, the communication between the first terminal and the second terminal includes: the first terminal sends control information and / or data to the second terminal, and includes the second terminal receiving control information and / or data sent by the first terminal. It can be understood that the first sidelink BWP resource configured by the access network device through the RRC dedicated information can support unicast, or it can be understood that the transmission type that can be supported is unicast, or it can be understood that the unicast service is supported. Of course, the first sidelink BWP resource configured by the access network device through RRC-specific information can also support multicast and / or broadcast, or it can be understood that it can also support a sidechain with a transmission type of multicast and / or a transmission type of broadcast Road communication, or understood as side link communication that can also support multicast services and / or broadcast services.

Step 202: The first terminal performs sidelink communication with the second terminal on the sidelink transmission BWP resource and / or the sidelink reception BWP resource according to the first configuration information.

As an implementation manner, the first configuration information includes information of a first sidelink BWP resource, and the first sidelink BWP resource includes information of a sidelink sending BWP resource and / or a sidelink receiving BWP resource, then the first The terminal may communicate with the second terminal according to the first sidelink BWP resource included in the first configuration information. For the specific meaning of the communication here, reference may be made to the relevant description in step 201 above.

That is, the first configuration information is used to indicate the first sidelink BWP resource, that is, the first configuration information itself does not include the first sidelink BWP resource, but the first configuration information indicates the first sidelink BWP resource, thereby The first terminal may determine the first sidelink BWP resource according to the first configuration information, and the first sidelink BWP resource may include a sidelink sending BWP resource and / or a sidelink receiving BWP resource, and then the first terminal may The first sidelink BWP resource communicates with the second terminal. For the specific meaning of the communication here, reference may be made to the relevant description in step 201 above. For example, the first configuration information may indicate the frequency domain position, for example, the frequency domain start position of the first sidelink BWP resource and the bandwidth of the first sidelink BWP resource, and the frequency domain of the first sidelink BWP resource Start position and end position in frequency domain, etc. For another example, the first configuration information may also indicate the identification and / or index of the first sidelink BWP resource, and so on.

Based on the above steps 201-202, the first sidelink BWP resource is configured to the first terminal through the first configuration information, and the first sidelink BWP resource includes a sidelink sending BWP resource and / or a sidelink receiving BWP Resources, so that the first terminal can send control information and / or data on the sidelink transmission BWP resource, and / or the first terminal can receive control information and / or data on the sidelink reception BWP resource. Thus, the configuration of the side link resources for the terminal is realized.

It should be noted that the sidelink sending BWP resource and the sidelink receiving BWP resource included in the first sidelink BWP resource configured by the first configuration information may be paired resources, where the paired resources may also be understood as the same The frequency domain resource and / or the same center frequency resource (center frequency point). In the case of pairing, the terminal can receive and / or send signals without changing the frequency domain resource or the center frequency point, reducing the processing complexity of the terminal. Of course, the side-link transmission BWP resource and the side-link reception BWP resource included in the first side-link BWP resource may not be paired resources. This application is not limited.

Optionally, because the terminal outside the coverage may receive only the side signal of the broadcast type or only the side signal of the broadcast, or only the side signal of the broadcast service. Because the broadcast sidelink signal requires that all terminals can receive and / or transmit, the transmission resources and / or reception resources of the broadcast signal can be limited to a certain bandwidth, so in this case the sidelink transmission resources and The sidelink reception resources may be located in the same sidelink BWP. At this time, the terminal does not need to change the frequency domain position of the BWP when receiving and sending control information and / or data on the side link resource. For example, when the side link resources are pre-configured, the pre-configured side link sending BWP and the side link receiving BWP can be paired, that is, the side link sending BWP and the side link receiving BWP are the same, and the terminal can be in the side link Road BWP centering performs side-link communication, including sending and / or receiving control information and / or data on side-link resources.

Optionally, because the terminal outside the coverage needs to support broadcast, multicast, and unicast sidelink communication, the sending sidelink resource may be a sideband BWP with a smaller bandwidth resource, and the receiving sidelink resource may It is a side link BWP with large bandwidth resources. The side-link transmission BWP and the side-link reception BWP configured at this time may be different. For example, when the side link resources are pre-configured, the side link sending BWP and the side link receiving BWP are not paired. When the terminal receives and sends control information and / or data on the side link resource, it needs to change the BWP frequency domain position. That is, the side link transmission BWP and the side link reception BWP are different. For example, as shown in FIG. 4, it is a schematic diagram of the pairing situation of the side link sending BWP and the side link receiving BWP.

Optionally, the concept of pairing may only involve the relationship of frequency domain resources, and does not limit the relationship of time domain resources.

In addition, there can be multiple configuration methods for the configuration of the sidelink resources, because the terminal only needs to send on a section of resources when sending the sidelink signal. In this case, the BWP sent by the sidelink can be a section of relatively small bandwidth. Domain resources. The terminal needs to receive sidelink signals under multiple transmission types. In order to ensure that the terminal can receive sidelink signals sent by other terminals, the sidelink reception BWP can be a frequency domain resource with a relatively large bandwidth. That is, the side link sending BWP and the side link receiving BWP may be different frequency domain resources, that is, it may be called that the side link sending BWP and the side link receiving BWP are not paired. In this case, the terminal can work on a small-bandwidth BWP when sending the sidelink signal, which can achieve the effect of energy saving of the terminal. In addition, the receiving BWP can be a large-bandwidth BWP, which can avoid the miss of the sidelink signal or Missed inspection.

Optionally, the matching schemes corresponding to different configuration methods may be different.

For example, the pre-configured sidelink transmission BWP and the sidelink reception BWP can be paired, and the sidelink transmission BWP and the sidelink reception BWP configured by the system information and / or RRC signaling can be unpaired.

For example, when the network device configures the side link resource to the terminal through the system information, the side link sending BWP may be different from the side link receiving BWP. That is, the side-link transmission BWP and the side-link reception BWP configured by the system information may not be paired. For example, when the network device configures the side link resource to the terminal through RRC signaling, the side link sending BWP and the side link receiving BWP may be different. That is, the side link sending BWP and the side link receiving BWP configured by RRC signaling may not be paired.

Further, whether the terminal supports pairing of side-link transmission BWP and side-link reception BWP may depend on the capability of the terminal.

For example, the capability of the terminal may be whether the terminal supports different transmission link (TX Chain) and reception link (RX Chain) bandwidths, or whether the terminal supports switching between side link transmission BWP and side link reception BWP.

For example, if the terminal supports a different transmission link (TX Chain) bandwidth and a reception link (RX Chain) bandwidth, the terminal can support side-link transmission BWP and side-link reception BWP not paired, and, side-link transmission BWP Pair with the side link receiving BWP. For example, if the terminal does not support the bandwidth of the transmission link (TX) and the bandwidth of the reception link (RX), the terminal may only support pairing of the side link transmission BWP and the side link reception BWP.

For example, if the terminal supports the switching between side-link transmission BWP and side-link reception BWP, the terminal may support the pairing of side-link transmission BWP and side-link reception BWP, and the pairing of side-link transmission BWP and side-link reception BWP . For example, if the terminal does not support the switching of the side-link transmission BWP and the side-link reception BWP, the UE may only support the pairing of the side-link transmission BWP and the side-link reception BWP.

As an implementation manner, when the first terminal supports pairing, the first terminal may also report the pairing capability of the first terminal to a network device (such as an access network device or a network management system) before step 201 above. The pairing capability is used to Instruct the first terminal to support pairing.

As another implementation manner, when the first terminal does not support pairing, the first terminal may also report the pairing capability of the first terminal to a network device (such as an access network device or a network management system) before step 201 described above. Used to indicate that the first terminal does not support pairing.

In this way, the network device can configure appropriate sidelink resources for the first terminal according to whether the first terminal supports pairing.

For the above step 201, different implementation methods are described below.

Implementation method one, the first configuration information in the above step 201 corresponds to the first configuration mode, that is, the first configuration information is sent to the first terminal in the first configuration mode, and the side link configured by the first configuration information receives the BWP resource It includes sidelink transmission resources configured in the second configuration mode, and / or sidelink transmission resources configured in the third configuration mode.

Optionally, the sidelink transmission resources may be sidelink transmission BWP resources and / or sidelink transmission resource pools.

It should be noted that, in the above-mentioned expression method (or referred to as the first expression method), the sidelink reception BWP resource is a reception resource relative to the first terminal. The side-link transmission resource configured by the second configuration mode is a transmission resource relative to a second terminal communicating with the first terminal, but may be a reception resource relative to the first terminal. The side-link transmission resource configured in the third configuration mode belongs to the transmission resource for the third terminal communicating with the first terminal, but may be the reception resource relative to the first terminal. The second terminal and the third terminal may be the same terminal.

Optionally, the above technical solution may also adopt the second expression manner as follows: That is, the first configuration information is sent to the first terminal by using the first configuration manner, and the sidelink receiving BWP resource configured by the first configuration information includes the first Sidelink receiving resources configured in the second configuration mode, and / or sidelink receiving resources configured in the third configuration mode. At this time, the so-called "reception" is relative to the first terminal.

Optionally, if the transmission direction of the signal carried on the resource is ignored, the above technical solution may also adopt the following third expression: the first configuration information is sent to the first terminal in the first configuration, and the first The sidelink BWP resource configured by the configuration information includes the sidelink resource configured by the second configuration mode, and / or the sidelink resource configured by the third configuration mode.

The following embodiments are described using the first form of expression as an example.

For this implementation, it includes multiple application scenarios, which are described separately below.

In an implementation manner, the first configuration mode is system information configuration or RRC common information configuration, and the second configuration mode is pre-configuration, then the sidelink receiving BWP resource configured by system information configuration or RRC public information may include pre-configuration Sidelink transmission resources. Based on this implementation, the first terminal may receive both system information or RRC common information and pre-configured information, and the sidelink received BWP resources configured by the system information or RRC common information include pre-configured sidelink transmission Resources. The sidelink receiving BWP resource configured by the system information configuration or RRC common information includes a preconfigured sidelink transmission resource, because other terminals such as the second terminal can broadcast sidelinks on the preconfigured sidelink transmission resource Signal transmission, so the first terminal can receive the broadcast sidelink signal on the sidelink receiving BWP resource of the system information or RRC common information. In addition, in actual communication, since other terminals such as a third terminal can send multicast sidelink signals on the sidelink transmission resources configured by the system information or RRC common information, the first terminal can send The multicast sidelink signal is received on the sidelink receiving BWP resource of the RRC common information. Therefore, when the side information receiving BWP resource configured by the system information configuration or RRC common information is activated, the first terminal can both receive the group on the side information receiving BWP resource configured by the system information configuration or RRC common information. The broadcasted data and / or control information may also receive the broadcasted data and / or control information.

Optionally, the activation of the BWP resource in this application may be the activation of the BWP resource through configuration information, the activation of the BWP resource through control information, or the activation of the BWP resource according to a preset rule, or it may also be through other means. Activate BWP resources, specifically, this application does not limit it.

Optionally, the activated BWP resource in this application may be understood as the BWP resource currently operated or communicated by the terminal. At the physical level, "activation" can be achieved, for example, by switching the radio frequency or adjusting the filter tap coefficients. For example, the resource for activating BWP is to turn on the radio frequency of the corresponding BWP resource, or the resource for activating BWP is to adjust the filter tap coefficient of the corresponding BWP resource.

Optionally, the terminal can receive a physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH), a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH), and a physical sidelink discovery channel on the activated BWP resource. At least one of Physical Sidelink Discovery Channel (PSDCH), Physical Sidelink Broadcast Channel (Physical Sidelink Broadcast Channel, PSBCH). And / or, the terminal can also send an uplink reference signal (including uplink DMRS), a physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH), and a physical sidelink control channel (Physical Sidelink Control Channel) on the activated BWP resource. PSCCH), physical sidelink uplink control channel (physical sidelink upcontrol channel, PSUCCH), physical sidelink discovery channel (Physical Sidelink Discovery Channel, PSDCH), physical sidelink broadcast channel (Physical Sidelink Broadcast Channel, PSBCH) At least one item.

Therefore, the first terminal can receive the multicast or broadcast sideband on the sidelink receiving BWP resource configured by the system information or RRC common information. Link signal. In addition, in actual communication, since other terminals such as a third terminal can send unicast sidelink signals on the sidelink transmission resources configured by the RRC dedicated information, the first terminal can send the system information or RRC public information The unicast sidelink signal is received on the sidelink receiving BWP resource.
