4. Configuration mode of side link resource of terminal
First, pre-configuration
Such as pre-configuring the sidelink resources for the terminal by the operator or pre-configuring the sidelink resources for the terminal in a predefined manner in a standard protocol.
Through the pre-configured configuration mode, the side link resources can be configured for a plurality of terminals, and in the specific implementation, the network management system of an operator can respectively send pre-configured information to each terminal, wherein the pre-configured information is used for respectively configuring the side link resources for each terminal. Since the preconfiguration information is sent to a plurality of terminals, the sidelink resource configured by the preconfiguration information can be used for broadcast transmission between the terminals, for example, the sidelink resource configured by the preconfiguration information can be used by the terminal 1 to broadcast data and/or control information, and other terminals, for example, the terminal 2, can receive data and/or control information on the sidelink resource. Of course, in practical applications, the sidelink resource configured by the pre-configuration information may also be used for multicast transmission and/or for unicast transmission, which is not limited in this application.
Optionally, the one or more terminals may refer to terminals under the service of the operator.
Alternatively, the one or more terminals may refer to one or more terminals that may receive the operator pre-configuration information, for example, all terminals served by one cell. Mode two, system information configuration or RRC common information configuration
Such as system information or RRC common information sent by the access network device to the terminal. The system information or common RRC information may be a cell-level parameter.
In a specific implementation, the access network device may send system information or RRC common information to a group of terminals, where the system information or RRC common information is used to configure sidelink resources for each terminal. Since the system information or the RRC common information is sent to a group of terminals, the sidelink resource configured by the system information or the RRC common information may be used for multicast transmission between terminals in the group, for example, the sidelink resource configured by the system information or the RRC common information may be used by the terminal 1 to multicast data and/or control information, and other terminals in the group, for example, the terminal 2, may receive data or control information on the sidelink resource.
Optionally, the group of terminals may include one or more terminals.
Alternatively, the group of terminals may refer to one or more terminals that may receive the system information or the RRC common information. For example, a cell may divide the terminals it serves into multiple groups, of which the group is one.
Certainly, in practical applications, the sidelink resource configured by the system information or the RRC common information may also be used for unicast transmission and/or broadcast transmission, which is not limited in the present application.
Mode three, RRC dedicated information configuration
Such as RRC dedicated information sent by the access network device to the terminal. The RRC dedicated information may be parameters at the terminal level (or referred to as UE level parameters) for which parameter configuration is performed.
For the configuration mode of the RRC dedicated information, the dedicated RRC resource may be configured for a single terminal, and in a specific implementation, the dedicated RRC information may be sent by the access network device to the single terminal, where the dedicated RRC information is used to configure the dedicated link resource for the terminal. Since the RRC dedicated information is addressed to a single terminal, the sidelink resource configured by the RRC dedicated information may be used for unicast transmission between terminals in the group, for example, the terminal 1 may unicast data or control information to the terminal 2 using the sidelink resource configured by the RRC dedicated information.
Certainly, in practical applications, the sidelink resource configured by the RRC dedicated information may also be used for broadcast transmission and/or multicast transmission, and the application is not limited in this application.
5. Type of transmission
In this application, the transmission types may include unicast, multicast, broadcast, and the like. Here, unicast (unicast) may refer to communication between one terminal and another terminal. Multicast (groupcast) may refer to communication between one terminal and a group of terminals. Broadcast (broadcast) may refer to communication between one terminal and a plurality of terminals. Alternatively, broadcasting may refer to communication between one terminal and all terminals in a cell, or understood as communication between one terminal and groups of terminals.
6. Type of service
In the present application, the service types may include unicast service, multicast service, broadcast service, and the like.
Alternatively, the traffic types may include enhanced Mobile Broadband (eMBB) traffic, ultra-Reliable and Low-Latency Communication (URLLC) traffic, machine Type Communication (MTC) traffic, and the like.
As shown in fig. 2, a method for configuring sidelink resources provided by the present application includes the following steps:
in step 201, the first terminal receives first configuration information of a sidelink resource sent by the network device, where the sidelink resource configured by the first configuration information includes a first sidelink bandwidth part BWP resource, and the first sidelink BWP resource includes a sidelink sending BWP resource and/or a sidelink receiving BWP resource.
In one implementation, the network device is a network management system of an operator, and the first configuration information may be pre-configuration information, where the first configuration information is used by the terminal to determine the sidelink resource. For example, the first configuration information may include information of one or more sidelink resources, or the first configuration information is used to indicate one or more sidelink resources, and the first terminal may determine, after receiving the first configuration information, the one or more sidelink resources that the first configuration information includes or indicates. 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 transmit BWP resource and/or a sidelink receive BWP resource. In this implementation, the first terminal may be any terminal under base station coverage or outside base station coverage, that is, terminals under base station coverage or outside base station coverage may be referred to as a first terminal, or it is understood that, for terminals under base station coverage or outside base station coverage, the sidelink resources may be configured through the first configuration information, and of course, terminals under base station coverage or outside base station coverage may also be referred to as a second terminal. For example, when only one terminal is referred to, the terminal may be referred to as a first terminal, and when two terminals are referred to, for distinction, one terminal may be referred to as a first terminal and the other terminal may be referred to as a second terminal. Accordingly, communication between terminals under or outside the coverage of the base station may use the first sidelink BWP resource configured by the first configuration information, where the communication may include transmitting 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 control information and/or data and the like sent by the second terminal. It is understood that the first sidelink BWP resource configured by the network management system through the pre-configuration information may support broadcast transmission, or may be understood as a sidelink communication in which the transmission type is broadcast, or may be understood as a sidelink communication in which a broadcast service may be supported. Of course, the first sidelink BWP resource configured by the network management system through the pre-configuration information may also support multicast and/or unicast, or may be understood as sidelink communication whose transmission type is multicast and/or transmission type is unicast, or may be understood as sidelink communication which may also support multicast service and/or unicast service.
In yet another implementation, the network device is an access network device, and the first configuration information may be system information or RRC common information, and the first configuration information is used for the terminal to determine the sidelink resource. For example, the first configuration information may include information of one or more sidelink resources, or the first configuration information is used to indicate one or more sidelink resources, and the first terminal may determine, after receiving the first configuration information, the one or more sidelink resources that the first configuration information includes or indicates. 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 transmit BWP resource and/or a sidelink receive BWP resource. It should be noted that, in this implementation, the first terminal may be any terminal in a group of terminals under the coverage of the base station, that is, any terminal in the group of terminals under the coverage of the base station may be referred to as a first terminal, or it is understood that, for any terminal in the group of terminals under the coverage of the base station, the configuration of the sidelink resource may be performed through the first configuration information, and of course, any terminal in the group under the coverage of the base station may also be referred to as a second terminal. For example, when only one terminal is mentioned, any terminal in the group may be referred to as a first terminal, and when two terminals in the group are mentioned, for distinction, one terminal may be referred to as a first terminal and the other terminal may be referred to as a second terminal. Accordingly, any two terminals in a group under the coverage of the base station can communicate with each other using the first BWP resource configured by the first configuration information, where the communication may include transmitting 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 sends control information and/or data to the second terminal, and the second terminal receives the control information and/or data sent by the first terminal. It is understood that the first sidelink BWP resource configured by the access network device through the system information configuration or the RRC common information may support multicast, or may be understood as sidelink communication whose transmission type is multicast, or may be understood as sidelink communication which may support multicast service. Of course, the first sidelink BWP resource configured by the access network device through the system information configuration or the RRC common information may also support unicast and/or broadcast, or be understood as a sidelink communication with a transmission type of unicast and/or a transmission type of broadcast.
In yet another implementation, the network device is an access network device, and the first configuration information may be RRC dedicated information, where the first configuration information is used by the terminal to determine the sidelink resource. For example, the first configuration information may include information of one or more sidelink resources, or the first configuration information is used to indicate one or more sidelink resources, and the first terminal may determine, after receiving the first configuration information, the one or more sidelink resources that the first configuration information includes or indicates. The sidelink resource configured by the first configuration information comprises a first sidelink BWP resource, and the first sidelink BWP resource may comprise a sidelink transmit BWP resource and/or a sidelink receive BWP resource. In this implementation, the first terminal may be any terminal under the coverage of the base station, that is, any terminal under the coverage of the base station may be referred to as a first terminal, or it is understood that any terminal under the coverage of the base station may perform the configuration of the sidelink resource through the first configuration information, and of course, any terminal under the coverage of the base station may also be referred to as a second terminal. For example, when only one terminal is mentioned, any terminal under the coverage of the base station may be referred to as a first terminal, and when two terminals under the coverage of the base station are mentioned, for distinction, one terminal may be referred to as a first terminal and the other terminal may be referred to as a second terminal. Therefore, when any two terminals under the coverage of the base station are configured with the first bypass BWP resource, the two terminals can communicate with each other using the first bypass BWP resource configured by the first configuration information, where the communication can include sending control information and/or data, and the communication can 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 the second terminal receives the control information and/or data sent by the first terminal. It is understood that the first bypass link BWP resource configured by the access network device through the RRC dedicated information may support unicast, or may be understood as a transmission type that may be supported as unicast, or may be understood as supporting unicast traffic. Of course, the first sidelink BWP resource configured by the access network device through the RRC dedicated information may also support multicast and/or broadcast, or may be understood as a sidelink communication with a transmission type of multicast and/or a transmission type of broadcast, or may be understood as a sidelink communication with a multicast service and/or a broadcast service.
Step 202, the first terminal performs sidelink communication with the second terminal on the sidelink transmitting BWP resource and/or the sidelink receiving BWP resource according to the first configuration information.
As one implementation, the first configuration information includes information of a first bypass BWP resource, and the first bypass BWP resource includes information of a bypass transmission BWP resource and/or a bypass reception BWP resource, and the first terminal may communicate with the second terminal according to the first bypass BWP resource included in the first configuration information. The specific meaning of the communication here can refer to the related description in step 201 above.
That is, the first configuration information is used to indicate the first bypass BWP resource, i.e., the first configuration information itself does not include the first bypass BWP resource, but the first configuration information indicates the first bypass BWP resource, so that the first terminal may determine the first bypass BWP resource according to the first configuration information, and the first bypass BWP resource may include the bypass transmission BWP resource and/or the bypass reception BWP resource, and thus the first terminal may communicate with the second terminal according to the first bypass BWP resource. The specific meaning of the communication here can refer to the related description in step 201 above. For example, the first configuration information may indicate frequency domain positions, such as a frequency domain starting position and a bandwidth of the first bypass BWP resource, a frequency domain starting position and a frequency domain ending position of the first bypass BWP resource, and the like. As another example, the first configuration information may also indicate an identification and/or index of the first bypass BWP resource, etc.
Based on the above steps 201-202, the first sidelink BWP resource is configured to the first terminal by the first configuration information, the first sidelink BWP resource comprises a sidelink transmission BWP resource and/or a sidelink reception BWP resource, so that the first terminal can transmit 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. Therefore, 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 frequency domain resource and/or the same center frequency resource (center frequency point). Under the condition of pairing, the terminal can receive and/or send signals without changing frequency domain resources or central frequency points, so that the processing complexity of the terminal is reduced. Of course, the sidelink transmitting BWP resource and the sidelink receiving BWP resource included in the first sidelink BWP resource may not be paired resources. The present application is not limited.
Alternatively, the out-of-coverage terminal may receive only sidelink signals with a transmission type of broadcast or only broadcast, or only sidelink signals of broadcast traffic. Since the broadcasted sidelink signal requires that all terminals can receive and/or transmit, the transmission resources and/or reception resources of the broadcasted signal may be limited within a certain bandwidth, so that in this case the sidelink transmission resources and the sidelink reception resources may be located in the same sidelink BWP. The terminal does not need to change the frequency domain position of the BWP when receiving and transmitting control information and/or data on the side link resources. For example, when the sidelink resource is preconfigured, the preconfigured sidelink sending BWP and the sidelink receiving BWP may be paired, that is, the sidelink sending BWP and the sidelink receiving BWP are the same, and at this time, the terminal may perform sidelink communication in the sidelink BWP pair, including sending and/or receiving control information and/or data on the sidelink resource.
Optionally, since the out-of-coverage terminal needs to support broadcast, multicast and unicast sidelink communication, the sending sidelink resource may be a sidelink BWP with smaller bandwidth resource, and the receiving sidelink resource may be a sidelink BWP with larger bandwidth resource. The sidelink transmit BWP and sidelink receive BWP configured at this time may be different. For example, when the sidelink resources are pre-configured, the sidelink transmitting BWP and the sidelink receiving BWP are not paired. When the terminal receives and transmits control information and/or data on the side link resource, the frequency domain position of the BWP needs to be changed. I.e. the sidelink transmitting BWP is different from the sidelink receiving BWP. For example, as shown in fig. 4 in particular, a diagram of a BWP pairing situation for side link transmission and side link reception is shown.
Alternatively, the concept of pairing may relate to the relationship of frequency domain resources only, and does not limit the relationship of time domain resources.
In addition, there may be multiple configurations for the configuration of the sidelink resource, because the terminal only needs to transmit on a segment of resource when transmitting the sidelink signal, and the sidelink transmission BWP may be a segment of frequency domain resource with relatively small bandwidth. The terminal needs to receive sidelink signals under multiple transmission types, and in order to ensure that the terminal can receive sidelink signals sent by other terminals, the sidelink reception BWP may be a segment of frequency domain resource with a relatively large bandwidth. I.e., the sidelink transmitting BWP and the sidelink receiving BWP may be different frequency domain resources, i.e., may be referred to as a sidelink transmitting BWP and a sidelink receiving BWP are not paired. In this case, the terminal may operate on a small bandwidth BWP when transmitting the sidelink signal, thereby achieving the effect of saving power for the terminal, and the receiving BWP may be a large bandwidth BWP, thereby avoiding missing or missing of the sidelink signal.
Optionally, the pairing schemes corresponding to different configuration modes may be different.
For example, the pre-configured sidelink transmitting BWP and sidelink receiving BWP may be paired, and the system information and/or RRC signaling configured sidelink transmitting BWP and sidelink receiving BWP may not be paired.
The sidelink transmission BWP may be different from the sidelink reception BWP, such as when the network device configures sidelink resources to the terminal through system information. That is, the system information configured sidelink transmitting BWP and the sidelink receiving BWP may not be paired. For example, when the network device configures the sidelink resource to the terminal through RRC signaling, the sidelink transmission BWP and the sidelink reception BWP may be different. That is, the sidelink sending BWP and sidelink receiving BWP configured by RRC signaling may not be paired.
Further, whether the terminal supports sidelink transmitting BWP and sidelink receiving BWP pairing may be terminal-dependent capabilities.
For example, the capability of the terminal may be whether the terminal supports different bandwidths for a transmission link (TX Chain) and a reception link (RX Chain), or whether the terminal supports switching between a side link transmission BWP and a side link reception BWP.
For example, if the bandwidth of the transmit link (TX Chain) and the bandwidth of the receive link (RX Chain) supported by the terminal are different, the terminal may support the unpaired sidelink transmit BWP and sidelink receive BWP, and the paired sidelink transmit BWP and sidelink receive BWP. For example, if the bandwidth of the terminal that does not support the transmission link (TX Chain) is different from the bandwidth of the reception link (RX Chain), the terminal may support only the sidelink transmission BWP and the sidelink reception BWP pairing.
For example, if the terminal supports handover of a sidelink transmission BWP and a sidelink reception BWP, the terminal may support unpaired sidelink transmission BWP and sidelink reception BWP, and paired sidelink transmission BWP and sidelink reception BWP. The UE may only support the sidelink-send BWP and sidelink-receive BWP pairing, e.g. if the terminal does not support the handover of sidelink-send BWP and sidelink-receive BWP.
As an implementation manner, when the first terminal supports pairing, before step 201, the first terminal may also report the pairing capability of the first terminal to the network device (such as an access network device or a network management system), where the pairing capability is used to indicate that the first terminal supports pairing.
As another implementation manner, when the first terminal does not support pairing, before the step 201, 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), where the pairing capability is used to indicate that the first terminal does not support pairing.
In this way, the network device may configure the first terminal with appropriate sidelink resources depending on whether the first terminal supports pairing.
For the above step 201, different implementation methods are given below for explanation.
In the first implementation method, the first configuration information in 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 sidelink reception BWP resource configured by the first configuration information includes a sidelink transmission resource configured by the second configuration mode and/or a sidelink transmission resource configured by the third configuration mode.
Optionally, the sidelink transmission resource may be a sidelink transmission BWP resource and/or a sidelink transmission resource pool.
It should be noted that, in the above expression (or referred to as the first expression), the sidelink reception BWP resource is a reception resource corresponding to the first terminal. The sidelink transmission resource configured by the second configuration is a transmission resource with respect to a second terminal communicating with the first terminal, but may be a reception resource with respect to the first terminal. The sidelink transmission resource configured by the third configuration belongs to a transmission resource for a third terminal communicating with the first terminal, but may be a reception resource with respect to the first terminal. Wherein the second terminal and the third terminal may be the same terminal.
Optionally, the above technical solution may also adopt the following second expression: that is, the first configuration information is sent to the first terminal in the first configuration manner, and the sidelink reception BWP resource configured by the first configuration information includes a sidelink reception resource configured by the second configuration manner and/or a sidelink reception resource configured by the third configuration manner. In this case, the term "reception" refers to the first terminal.
Optionally, if the transmission direction of the signal carried on the resource is ignored, the following third expression manner may also be adopted in the above technical solution: the first configuration information is sent to the first terminal by adopting a first configuration mode, and the sidelink BWP resource configured by the first configuration information comprises a sidelink resource configured by a second configuration mode and/or a sidelink resource configured by a third configuration mode.
The following embodiments are described by way of example in the first expression.
For this implementation, a plurality of application scenarios are included, which are described below.
In an implementation, the first configuration is system information configuration or RRC common information configuration, and the second configuration is pre-configuration, and the system information configuration or RRC common information configuration sidelink reception BWP resource may include a pre-configured sidelink transmission resource. Based on the implementation, the first terminal may receive both the system information or the RRC common information and the pre-configuration information, and the system information configuration or the RRC common information configuration sidelink reception BWP resource includes a pre-configured sidelink transmission resource. The system information configured or RRC common information configured sidelink reception BWP resource includes a pre-configured sidelink transmission resource on which other terminals, such as the second terminal, can transmit a broadcast sidelink signal, so that the first terminal can receive the broadcast sidelink signal on the system information or RRC common information sidelink reception BWP resource. In addition, in actual communication, since other terminals such as a third terminal may perform multicast sidelink signal transmission on the sidelink transmission resource configured by the system information or RRC common information, the first terminal may receive the multicast sidelink signal on the sidelink reception BWP resource of the system information or RRC common information. Therefore, when the system information configured or RRC common information configured sidelink reception BWP resource is activated, the first terminal may receive both multicast data and/or control information and broadcast data and/or control information on the system information configured or RRC common information configured sidelink reception BWP resource. Or, it is understood that the system information configuration or RRC common information configuration sidelink reception BWP resource may support sidelink communication with a broadcast transmission type or multicast transmission type. Or, it is understood that the system information configuration or RRC common information configuration sidelink reception BWP resource may support sidelink communication for both broadcast type services and multicast type services.
Optionally, the BWP resource may be activated through configuration information, or through control information, or according to a preset rule, or through other manners, which is not limited in this application.
Alternatively, the activated BWP resource in this application may be understood as the BWP resource currently operated or communicating by the terminal. On the physical level, "activation" can be achieved, for example, by switching the radio frequency, or adjusting the filter tap coefficients. Such as activating BWP resources by turning on radio frequencies of the corresponding BWP resources, or activating BWP resources by adjusting filter tap coefficients of the corresponding BWP resources, etc.
Optionally, the terminal may receive at least one of a Physical Sidelink Shared Channel (PSCCH), a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Discovery Channel (PSDCH), and a Physical Sidelink Broadcast Channel (PSBCH) on the activated BWP resource. And/or the terminal may further transmit at least one of an uplink reference signal (including an uplink DMRS), a Physical Sidelink Shared Channel (psch), a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink uplink Control Channel (PSCCH), a Physical Sidelink Discovery Channel (PSDCH), a Physical Sidelink Broadcast Channel (PSBCH), on the activated BWP resource.
The explanation of the concept of "activation" of BWP resources herein is also applicable to other places related to "activation" in this application, and will not be described in detail later.
In yet another implementation, the first configuration is RRC dedicated information configuration, the second configuration is pre-configuration, and the third configuration is system information configuration or RRC common information configuration, and the sidelink reception BWP resource configured by the RRC dedicated information may include a pre-configured sidelink transmission resource and/or a system information configuration or RRC common information configured sidelink transmission resource. Based on this implementation, the first terminal may receive both RRC dedicated information and pre-configured information, and/or system information or RRC common information, and the sidelink reception BWP resource configured by the RRC dedicated information includes a pre-configured sidelink transmission resource, and/or a sidelink transmission resource configured by the system information or RRC common information. For example, when the sidelink reception BWP resource configured by the RRC dedicated information includes the preconfigured sidelink transmission resource, the first terminal may receive the broadcast sidelink signal on the preconfigured sidelink reception BWP resource since other terminals, such as the second terminal, may perform transmission of the broadcast sidelink signal on the preconfigured sidelink transmission resource. In addition, in actual communication, since other terminals, such as a third terminal, may perform transmission of multicast or unicast sidelink signals on the sidelink transmission resource configured by the RRC dedicated information, the first terminal may receive the multicast or unicast sidelink signals on the sidelink reception BWP resource configured by the RRC dedicated information. Therefore, when the RRC dedicated information configured sidelink reception BWP resource is activated, the first terminal may receive both unicast or multicast data and/or control information and broadcast data and/or control information on the RRC dedicated information configured sidelink reception BWP resource. Or, it is understood that the sidelink reception BWP resource configured by the system information configuration or the RRC common information configuration may support sidelink communication with a transmission type of unicast or a transmission type of multicast, or may support sidelink communication with a transmission type of broadcast. Alternatively, it is understood that the peer link reception BWP resource configured by the RRC dedicated information may support peer link communication of unicast type traffic or multicast type traffic, or may support peer link communication of broadcast type traffic. For another example, when the RRC dedicated information configured sidelink reception BWP resource includes a system information configured sidelink transmission resource or an RRC common information configured sidelink transmission resource, since other terminals such as the second terminal may perform multicast or broadcast sidelink signal transmission on the system information configured sidelink transmission resource or the RRC common information configured sidelink transmission resource, the first terminal may receive the multicast or broadcast sidelink signal on the system information configured sidelink reception BWP resource or the RRC common information configured sidelink reception BWP resource. In addition, in actual communication, since other terminals such as a third terminal can perform unicast sidelink signal transmission on the sidelink transmission resource configured by the RRC dedicated information, the first terminal can receive the unicast sidelink signal on the sidelink reception BWP resource of the system information or RRC common information. Therefore, when the RRC dedicated information configured sidelink reception BWP resource is activated, the first terminal may receive both unicast data and/or control information and multicast or broadcast data and/or control information on the RRC dedicated information configured sidelink reception BWP resource. Or, it is understood that the sidelink reception BWP resource configured by the system information configuration or the RRC common information configuration may support sidelink communication with a transmission type of unicast or with a transmission type of multicast or with a transmission type of broadcast. Or, it is understood that the sidelink reception BWP resource configured by the RRC dedicated information may support sidelink communication for unicast type traffic, or may support sidelink communication for multicast type traffic or broadcast type traffic. For another example, when the RRC dedicated information configured sidelink reception BWP resource includes a pre-configured sidelink transmission resource and a sidelink transmission resource including a system information configuration or an RRC common information configuration, since other terminals such as the second terminal may transmit a multicast sidelink signal on the system information configuration or the RRC common information configured sidelink transmission resource and other terminals such as the third terminal may transmit a broadcast sidelink signal on the pre-configured sidelink transmission resource, the first terminal may receive the multicast and/or broadcast sidelink signal on the system information configuration or the RRC common information configured sidelink reception BWP resource. In addition, in actual communication, since other terminals such as a fourth terminal can perform unicast sidelink signal transmission on the sidelink transmission resource configured by the RRC dedicated information, the first terminal can receive the unicast sidelink signal on the sidelink reception BWP resource of the system information or RRC common information. Therefore, when the RRC dedicated information configured sidelink reception BWP resource is activated, the first terminal may receive both unicast data and/or control information and multicast data and/or control information and broadcast data and/or control information on the RRC dedicated information configured sidelink reception BWP resource. Or, it is understood that the sidelink reception BWP resource configured by the RRC dedicated message may support sidelink communication with a unicast transmission type, sidelink communication with a multicast transmission type, and sidelink communication with a broadcast transmission type. Or, it is understood that the sidelink reception BWP resource configured by the RRC dedicated information may support sidelink communication for unicast-type traffic, sidelink communication for multicast-type traffic, and sidelink communication for broadcast-type traffic.
In yet another implementation, the first configuration is pre-configured, the second configuration is RRC dedicated information configuration, and the third configuration is system information configuration or RRC common information configuration, and the pre-configured sidelink reception BWP resource may include a sidelink transmission resource configured by RRC dedicated information configuration and/or a sidelink transmission resource configured by system information configuration or RRC common information configuration. Based on this implementation, the first terminal may receive both the provisioning information and the RRC dedicated information and/or receive the system information or the RRC common information, and the sidelink reception BWP resource configured by the provisioning information includes a sidelink transmission resource configured by the RRC dedicated information and/or a sidelink transmission resource configured by the system information or the RRC common information. For example, when the preconfigured sidelink reception BWP resource includes an RRC dedicated information configured sidelink transmission resource, the first terminal may receive the unicast sidelink signal on the RRC dedicated information configured sidelink reception BWP resource since other terminals, such as the second terminal, may perform the unicast sidelink signal transmission on the RRC dedicated information configured sidelink transmission resource. In addition, in actual communication, since other terminals, such as a third terminal, may perform multicast or broadcast sidelink signal transmission on the preconfigured sidelink transmission resource, the first terminal may receive the multicast or broadcast sidelink signal on the preconfigured sidelink reception BWP resource. Therefore, when the preconfigured sidelink receiving BWP resource is activated, the first terminal may receive both unicast data and/or control information and broadcast and/or multicast data and/or control information on the preconfigured sidelink receiving BWP resource. Alternatively, the pre-configured sidelink reception BWP resource may support sidelink communications with a unicast transmission type or a multicast transmission type. Or it is understood that the pre-configured sidelink reception BWP resource may support sidelink communication for both unicast type traffic and broadcast type traffic or multicast type traffic. For another example, when the preconfigured sidelink reception BWP resource includes a system information configured or RRC common information configured sidelink transmission resource, since other terminals, such as the second terminal, may perform transmission of the multicast or unicast sidelink signal on the system information configured or RRC common information configured sidelink transmission resource, the first terminal may receive the multicast or broadcast sidelink signal on the preconfigured sidelink reception BWP resource. In addition, in actual communication, since other terminals such as a third terminal may perform transmission of the broadcast sidelink signal on the preconfigured sidelink transmission resource, the first terminal may receive the broadcast sidelink signal on the sidelink reception BWP resource of the system information or RRC common information. Therefore, when the preconfigured sidelink receiving BWP resource is activated, the first terminal may receive both broadcast data and/or control information and multicast or unicast data and/or control information on the preconfigured sidelink receiving BWP resource. Alternatively, the pre-configured sidelink reception BWP resource may support sidelink communications with either a broadcast transmission type or a multicast transmission type or a unicast transmission type. Or, it is understood that the pre-configured sidelink reception BWP resource may support sidelink communication for multicast type traffic or unicast type traffic, or for broadcast type traffic. For another example, when the preconfigured sidelink reception BWP resource includes a sidelink transmission resource configured by RRC dedicated information and a sidelink transmission resource configured by system information or RRC common information, since other terminals, for example, the second terminal, may transmit a multicast sidelink signal on the sidelink transmission resource configured by system information or RRC common information, and other terminals, for example, the third terminal, may transmit a unicast sidelink signal on the sidelink transmission resource configured by RRC dedicated information, the first terminal may receive the multicast and/or unicast sidelink signal on the system information configured or RRC common information configured sidelink reception BWP resource. In addition, in actual communication, since other terminals, such as a fourth terminal, may perform the transmission of the broadcast sidelink signal on the preconfigured sidelink transmission resource, the first terminal may receive the broadcast sidelink signal on the preconfigured sidelink reception BWP resource. Therefore, when the preconfigured sidelink receiving BWP resource is activated, the first terminal may receive both unicast data and/or control information, multicast data and/or control information, and broadcast data and/or control information on the preconfigured sidelink receiving BWP resource. Or, it is understood that the preconfigured sidelink receiving BWP resource may support sidelink communication with a unicast transmission type, sidelink communication with a multicast transmission type, or sidelink communication with a broadcast transmission type. Or, it is understood that the preconfigured sidelink reception BWP resource may support sidelink communication for both unicast type traffic and multicast type traffic, as well as broadcast type traffic.
It should be noted that the unicast type service may also be referred to as a unicast service, the multicast type service may also be referred to as a multicast service, and the broadcast type service may also be referred to as a broadcast service.
It should be noted that, if the first terminal receives multiple pieces of configuration information and one piece of configuration information configures one type of sidelink resource, the first terminal is subject to the sidelink resource configured later. For example, the first terminal receives the sidelink resource pre-configured by the network management system and receives the sidelink resource configured by the access network device, and then the sidelink resource configured by the access network device is used as the standard. For example, if the first terminal receives the sidelink resource configured by the access network device through the RRC common information and receives the sidelink resource configured by the access network device through the RRC dedicated information, the sidelink resource configured by the access network device through the RRC dedicated information is used as the standard.
It should be noted that, if the first terminal receives multiple pieces of configuration information, one piece of configuration information configures one type of sidelink resource, for example, the configuration information may be one or more of pre-configuration information, system information, RRC common information, and RRC dedicated information. If the first terminal receives the RRC dedicated information, the first terminal takes the sidelink resource configured by the RRC dedicated information as a standard; if the terminal does not receive the RRC dedicated information but receives the system information or the RRC common information, taking the sidelink resources configured by the system information or the RRC common information as the standard; and if the terminal does not receive the system information or the RRC public information and the terminal does not receive the RRC dedicated information, the side link resource configured by the pre-configuration information is used as the standard. For example, if the first terminal receives the sidelink resource preconfigured by the network management system and receives the sidelink resource configured by the access network device, the sidelink resource configured by the access network device is used as the standard. For example, if the first terminal receives the sidelink resource configured by the access network device through the RRC common information and receives the sidelink resource configured by the access network device through the RRC dedicated information, the sidelink resource configured by the access network device through the RRC dedicated information is used as the criterion.
It should be noted that, in a specific implementation of the first implementation method, when configuring the sidelink to receive the BWP resource, the first configuration information may include an identifier of the sidelink transmission resource configured by the second configuration method and/or an identifier of the sidelink transmission resource configured by the third configuration method.
For example, the second configuration mode configures 4 sidelink transmission resources, and the identifiers are resource 1, resource 2, resource 3, and resource 4, respectively. If the sidelink reception BWP resource configured by the first configuration information includes sidelink transmission resource 1 and sidelink transmission resource 2 configured by the second configuration method, the first configuration information may include the identifier of the sidelink transmission resource configured by the second configuration method, that is, resource 1 and resource 2.
For example, the third configuration mode configures 4 sidelink transmission resources, and the identifiers are resource 5, resource 6, resource 7, and resource 8, respectively. If the sidelink receiving BWP resource configured by the first configuration information includes the sidelink transmission resource 7 and the sidelink transmission resource 8 configured by the third configuration mode, the first configuration information may include the identifier of the sidelink transmission resource configured by the third configuration mode, that is, the resource 7 and the resource 8.
Through the above configuration, the first configuration information includes an identifier of the sidelink transmission resource configured by the second configuration, such as a resource pool identifier, or a transmission BWP identifier, and/or the first configuration information includes an identifier of the sidelink transmission resource configured by the third configuration, such as a resource pool identifier, or a transmission BWP identifier. The terminal and/or the network device may be understood as: when the configuration information of the receiving BWP includes the identifier of the sidelink transmission resource, the sidelink transmission resource corresponding to the identifier of the sidelink transmission resource (the "transmission" is for the second terminal and/or the third terminal) is the sidelink reception resource of the first terminal, and the first terminal may receive the sidelink signal in the sidelink reception resource.
In the second implementation method, the sidelink reception BWP resource configured by the first configuration information in step 201 is a sidelink reception BWP resource of the first transmission type, where the sidelink reception BWP resource of the first transmission type includes a sidelink transmission resource of the second transmission type and/or a sidelink transmission resource of the third transmission type.
In the above expression (which may also be referred to as a first expression), the sidelink reception BWP resource is a reception resource for the first terminal. The sidelink transmission resource of the second transmission type is a transmission resource with respect to a second terminal communicating with the first terminal, but may be a reception resource with respect to the first terminal. The sidelink transmission resource of the third transmission type may belong to a transmission resource for a third terminal in communication with the first terminal, but may be a reception resource with respect to the first terminal. Wherein the second terminal and the third terminal may be the same terminal.
Optionally, the above technical solution may also adopt the following second expression: i.e. the first configuration information, is sent to the first terminal and the sidelink reception BWP resource of the first transmission type comprises a sidelink reception resource of the second transmission type and/or a sidelink reception resource of the third transmission type. In this case, the term "reception" refers to the first terminal.
Optionally, if the transmission direction of the signal carried on the resource is ignored, the following third expression manner may also be adopted in the foregoing technical solution: the first configuration information is sent to the first terminal and the sidelink BWP resource of the first transmission type comprises a sidelink resource of the second transmission type and/or a sidelink resource of the second transmission type.
The following examples are all described by way of example in the first expression.
For the implementation, various application scenarios are included, which are described below.
In one implementation, the first transmission type is multicast and the second transmission type is broadcast, and the multicast sidelink reception BWP resource may include a broadcast sidelink transmission resource. Based on the implementation, the first configuration information may configure a sidelink reception BWP resource that may be multicast, and the multicast sidelink reception BWP resource may include a broadcast sidelink transmission resource. Since other terminals, such as the second terminal, may transmit the broadcast sidelink signal on the broadcast sidelink transmission resource, the first terminal may receive the broadcast sidelink signal on the multicast sidelink reception BWP resource. In addition, in actual communication, since other terminals, such as a third terminal, may perform multicast side link signal transmission on the multicast side link transmission resource, the first terminal may receive the multicast side link signal on the multicast side link reception BWP resource. Therefore, when the multicast sidelink reception BWP resource is activated, the first terminal may receive both multicast data and/or control information and broadcast data and/or control information on the multicast sidelink reception BWP resource. Or, it is understood that the multicast sidelink reception BWP resource may support sidelink communication with a broadcast transmission type or multicast transmission type. Or it is understood that the multicast sidelink reception BWP resource may support sidelink communication for both broadcast type traffic and multicast type traffic.
In yet another implementation, the first transmission type is unicast, the second transmission type is broadcast, and the third transmission type is multicast, and the unicast sidelink reception BWP resource includes a broadcast sidelink transmission resource and/or a unicast sidelink transmission resource. Based on the implementation, the unicast sidelink reception BWP resource may include a broadcast sidelink transmission resource, and/or a multicast sidelink transmission resource. For example, when the unicast sidelink reception BWP resource includes a broadcast sidelink transmission resource, the first terminal may receive the broadcast sidelink signal on the unicast sidelink reception BWP resource since other terminals, such as the second terminal, may transmit the broadcast sidelink signal on the broadcast sidelink transmission resource. In addition, in actual communication, since other terminals, such as a third terminal, may perform unicast sidelink signal transmission on the unicast sidelink transmission resource, the first terminal may receive the unicast sidelink signal on the unicast sidelink reception BWP resource. Thus, when the unicast sidelink reception BWP resource is activated, the first terminal may receive both unicast data and/or control information and broadcast data and/or control information on the unicast sidelink reception BWP resource. Alternatively, the unicast sidelink reception BWP resource may support sidelink communications with a transmission type of unicast or broadcast. Or it is understood that the unicast sidelink reception BWP resource may support sidelink communication for both unicast type traffic and broadcast type traffic. For another example, when the unicast sidelink reception BWP resource includes a multicast sidelink transmission resource, the first terminal may receive the multicast sidelink signal on the unicast sidelink reception BWP resource since other terminals, such as the second terminal, may perform multicast sidelink communication on the multicast sidelink transmission resource. In addition, in actual communication, since other terminals such as a third terminal can perform unicast sidelink signal transmission on the unicast sidelink transmission resource, the first terminal can receive the unicast sidelink signal on the unicast sidelink reception BWP resource. Therefore, when the unicast sidelink reception BWP resource is activated, the first terminal may receive both unicast data and/or control information and multicast data and/or control information on the unicast sidelink reception BWP resource. Alternatively, the unicast sidelink reception BWP resource may support sidelink communication with a unicast transmission type or multicast transmission type. Or, it is understood that the unicast sidelink reception BWP resource may support sidelink communication for both unicast-type traffic and multicast-type traffic. For another example, when the unicast sidelink reception BWP resource includes a broadcast sidelink transmission resource and a multicast sidelink transmission resource, the first terminal may receive the multicast and/or broadcast sidelink signal on the unicast sidelink reception BWP resource, since other terminals, such as the second terminal, may transmit the multicast sidelink signal on the multicast sidelink transmission resource, and other terminals, such as the third terminal, may transmit the broadcast sidelink signal on the broadcast sidelink transmission resource. In addition, in actual communication, since other terminals, such as a fourth terminal, may perform unicast sidelink signal transmission on the unicast sidelink transmission resource, the first terminal may receive the unicast sidelink signal on the unicast sidelink reception BWP resource. Therefore, when the unicast sidelink reception BWP resource is activated, the first terminal may receive both unicast data and/or control information, multicast data and/or control information, and broadcast data and/or control information on the unicast sidelink reception BWP resource. Or, it is understood that the unicast sidelink reception BWP resource may support sidelink communication with a transmission type of unicast, sidelink communication with a transmission type of multicast, or sidelink communication with a transmission type of broadcast. Or, it is understood that the unicast sidelink reception BWP resource may support sidelink communication for both unicast-type traffic and multicast-type traffic, as well as broadcast-type traffic.
In yet another implementation, the first transmission type is broadcast, the second transmission type is unicast, and the third transmission type is multicast, and the broadcasted sidelink reception BWP resource includes a multicast sidelink transmission resource and/or a unicast sidelink transmission resource. Based on the implementation, the broadcasted sidelink reception BWP resource may comprise a unicast sidelink transmission resource and/or a multicast sidelink transmission resource. For example, when the broadcasted sidelink reception BWP resource comprises a unicast sidelink transmission resource, the first terminal may receive the unicast sidelink signal on the unicast sidelink reception BWP resource since other terminals, such as the second terminal, may transmit the unicast sidelink signal on the unicast sidelink transmission resource. In addition, in actual communication, since other terminals such as a third terminal may perform the transmission of the broadcast sidelink signal on the broadcast sidelink transmission resource, the first terminal may receive the broadcast sidelink signal on the broadcast sidelink reception BWP resource. Thus, when the broadcasted sidelink reception BWP resource is activated, the first terminal may receive both unicast data and/or control information and broadcast data and/or control information on the broadcasted sidelink reception BWP resource. Alternatively, the broadcast sidelink reception BWP resource may support sidelink communications with a unicast transmission type or a broadcast transmission type. Or, it is understood that the broadcasted sidelink reception BWP resource may support sidelink communications for both unicast-type traffic and broadcast-type traffic. For another example, when the broadcast sidelink reception BWP resource includes a multicast sidelink transmission resource, the first terminal may receive the multicast sidelink signal on the broadcast sidelink reception BWP resource since other terminals, such as the second terminal, may transmit the multicast sidelink signal on the multicast sidelink transmission resource. In addition, in actual communication, since other terminals such as a third terminal may perform the transmission of the broadcast sidelink signal on the broadcast sidelink transmission resource, the first terminal may receive the broadcast sidelink signal on the broadcast sidelink reception BWP resource. Thus, when the broadcasted sidelink reception BWP resource is activated, the first terminal may receive both broadcasted data and/or control information and multicast data and/or control information on the broadcasted sidelink reception BWP resource. Or, it is understood that the broadcast sidelink reception BWP resource may support sidelink communications with a broadcast transmission type or multicast transmission type. Or it is understood that the broadcasted sidelink reception BWP resource may support sidelink communication for both multicast type traffic and broadcast type traffic. For another example, when the broadcast sidelink reception BWP resource includes a unicast sidelink transmission resource and a multicast sidelink transmission resource, the first terminal may receive the multicast and/or unicast sidelink signals on the broadcast sidelink reception BWP resource, since other terminals, such as the second terminal, may transmit multicast sidelink signals on the multicast sidelink transmission resource and other terminals, such as the third terminal, may transmit unicast sidelink signals on the unicast sidelink transmission resource. In addition, in actual communication, since other terminals such as a fourth terminal may perform transmission of the broadcast side-link signal on the broadcast side-link transmission resource, the first terminal may receive the broadcast side-link signal on the broadcast side-link reception BWP resource. Therefore, when the broadcasted sidelink reception BWP resource is activated, the first terminal may receive both unicast data and/or control information, multicast data and/or control information, and broadcast data and/or control information on the broadcasted sidelink reception BWP resource. Or, it is understood that the broadcast sidelink reception BWP resource may support sidelink communication with a unicast transmission type, sidelink communication with a multicast transmission type, or sidelink communication with a broadcast transmission type. Or, it is understood that the broadcast sidelink reception BWP resource may support sidelink communication for both unicast-type traffic and multicast-type traffic, as well as broadcast-type traffic.
It should be noted that the unicast type service may also be referred to as a unicast service, the multicast type service may also be referred to as a multicast service, and the broadcast type service may also be referred to as a broadcast service.
It should be noted that, if the first terminal receives multiple pieces of configuration information and one piece of configuration information configures one type of sidelink resource, the first terminal is subject to the sidelink resource configured later. For example, the first terminal receives the broadcasted sidelink resource first, and receives the multicast sidelink resource again, and takes the multicast sidelink resource as the standard. For example, if the first terminal receives the multicast sidelink resource first and receives the unicast sidelink resource again, the unicast sidelink resource is used as the standard.
It should be noted that, if the first terminal receives multiple pieces of configuration information, one piece of configuration information configures one type of sidelink resource, for example, the sidelink resource may be one or more of a broadcast sidelink resource, a multicast sidelink resource, and a unicast sidelink resource. If the terminal receives the unicast sidelink resource, the first terminal may take the unicast sidelink resource as a reference; if the terminal does not receive the unicast sidelink resource but receives the multicast sidelink resource, the multicast sidelink resource can be used as the standard; if the terminal does not receive the multicast sidelink resource, and the terminal does not receive the unicast sidelink resource, the broadcast sidelink resource may be used as the standard. For example, if the first terminal receives the broadcasted sidelink resource and receives the multicast sidelink resource, the multicast sidelink resource may be used as the criterion. For example, if the first terminal receives the multicast sidelink resource and receives the unicast sidelink resource, the unicast sidelink resource may be used as the standard.
It should be noted that, for the second implementation method, in a specific implementation, the configuration information of the first transmission type sidelink receiving BWP resource may include an identifier of a sidelink transmission resource of the second transmission type and/or an identifier of a sidelink transmission resource of the third transmission type.
For example, there are 4 sidelink transmission resources of the second transmission type, and the identifiers are resource 1, resource 2, resource 3, and resource 4, respectively. If the sidelink reception BWP resource of the first transmission type includes sidelink transmission resource 1 and sidelink transmission resource 2 of the second transmission type, the identification of the sidelink transmission resource of the second transmission type, that is, resource 1 and resource 2, may be included in the configuration information of the sidelink reception BWP resource of the first transmission type.
For example, there are 4 sidelink transmission resources of the third transmission type, and the identifiers are resource 5, resource 6, resource 7, and resource 8, respectively. If the sidelink reception BWP resource of the first transmission type includes a sidelink transmission resource 7 and a sidelink transmission resource 8 of a third transmission type, the identification of the sidelink transmission resource of the third transmission type, i.e. resource 7 and resource 8, may be included in the configuration information of the sidelink reception BWP resource of the first transmission type.
By the above configuration, the configuration information of the first transmission type sidelink receiving BWP resource includes an identifier of a sidelink transmitting resource of the second transmission type, such as a resource pool identifier, or a transmitting BWP identifier, and/or the configuration information of the first transmission type sidelink receiving BWP resource includes an identifier of a sidelink transmitting resource of the third transmission type, such as a resource pool identifier, or a transmitting BWP identifier. The terminal and/or the network device may be understood as: when the configuration information of the receiving BWP includes the identifier of the sidelink transmission resource, the sidelink resource corresponding to the identifier of the sidelink transmission resource is a sidelink reception resource of the first terminal, and the first terminal may receive a sidelink signal in the sidelink reception resource.
In the third implementation method, the sidelink reception BWP resource configured by the first configuration information in step 201 is a sidelink reception BWP resource of the first service type, where the sidelink reception BWP resource of the first service type includes a sidelink transmission resource of the second service type and/or a sidelink transmission resource of the third service type.
In the first expression (which may also be referred to as a first expression), the sidelink reception BWP resource is a reception resource for the first terminal. The sidelink transmission resource of the second traffic type is a transmission resource with respect to a second terminal communicating with the first terminal, but may be a reception resource with respect to the first terminal. The sidelink transmission resource of the third traffic type may belong to a transmission resource for a third terminal in communication with the first terminal, but may be a reception resource with respect to the first terminal. Wherein the second terminal and the third terminal may be the same terminal.
Optionally, the technical solution may also adopt a second expression manner as follows: i.e. the first configuration information, is sent to the first terminal and the sidelink reception BWP resource of the first traffic type comprises a sidelink reception resource of the second traffic type and/or a sidelink reception resource of the second traffic type. In this case, the term "reception" refers to the first terminal.

Or, it is understood that the sidelink reception BWP resource for unicast traffic may support sidelink communication for both unicast-type traffic and broadcast-type traffic. For another example, when the sidelink reception BWP resource of the unicast service includes a sidelink transmission resource of the multicast service, since other terminals, such as the second terminal, may perform sidelink communication for multicast on the sidelink transmission resource of the multicast service, the first terminal may receive the multicast sidelink signal on the sidelink reception BWP resource of the unicast service.

In yet another implementation, the first service type is a broadcast service, the second service type is a unicast service, and the third service type is a multicast service, and the BWP resource received by the sidelink of the broadcast service includes a sidelink transmission resource of the multicast service, and/or a sidelink transmission resource of the unicast service. Based on the implementation, the sidelink reception BWP resource for the broadcast traffic may include a sidelink transmission resource for the unicast traffic and/or a sidelink transmission resource for the multicast traffic. For example, when the sidelink reception BWP resource of the broadcast service includes a sidelink transmission resource of the unicast service, the first terminal may receive the unicast sidelink signal on the sidelink reception BWP resource of the unicast service because other terminals, such as the second terminal, may perform transmission of the unicast sidelink signal on the sidelink transmission resource of the unicast service. In addition, in actual communication, since other terminals such as a third terminal may perform transmission of the broadcast sidelink signal on the sidelink transmission resource of the broadcast service, the first terminal may receive the broadcast sidelink signal on the sidelink reception BWP resource of the broadcast service. Therefore, when the sidelink reception BWP resource of the broadcast service is activated, the first terminal may receive both unicast data and/or control information and broadcast data and/or control information on the sidelink reception BWP resource of the broadcast service. Or, it is understood that the sidelink reception BWP resource of the broadcast service may support sidelink communication with a transmission type of unicast or sidelink communication with a transmission type of broadcast. Or it is understood that the sidelink reception BWP resource for broadcast traffic supports sidelink communication for both unicast and broadcast type traffic. For another example, when the sidelink reception BWP resource of the broadcast service includes a sidelink transmission resource of the multicast service, the first terminal may receive the multicast sidelink signal on the sidelink reception BWP resource of the broadcast service because other terminals, such as the second terminal, may transmit the multicast sidelink signal on the sidelink transmission resource of the multicast service. In addition, in actual communication, since other terminals such as a third terminal may perform transmission of the broadcast sidelink signal on the sidelink transmission resource of the broadcast service, the first terminal may receive the broadcast sidelink signal on the sidelink reception BWP resource of the broadcast service. Therefore, when the sidelink reception BWP resource of the broadcast service is activated, the first terminal may receive both the broadcasted data and/or control information and the multicasted data and/or control information on the sidelink reception BWP resource of the broadcast service. Or, it is understood that the sidelink reception BWP resource of the broadcast service may support sidelink communication with a broadcast transmission type or multicast transmission type. Or, it is understood that the sidelink reception BWP resource of the broadcast service may support sidelink communication for both multicast-type services and broadcast-type services. For another example, when the BWP resource for broadcast service includes a BWP resource for unicast service and a BWP resource for multicast service, the first terminal may receive the multicast and/or unicast sidelink signals on the BWP resource for broadcast service because other terminals, such as the second terminal, may transmit multicast sidelink signals on the BWP resource for multicast service and other terminals, such as the third terminal, may transmit unicast sidelink signals on the BWP resource for unicast service. In addition, in actual communication, since other terminals such as a fourth terminal may perform transmission of the broadcast sidelink signal on the sidelink transmission resource of the broadcast service, the first terminal may receive the broadcast sidelink signal on the sidelink reception BWP resource of the broadcast service. Therefore, when the sidelink reception BWP resource of the broadcast service is activated, the first terminal may receive both unicast data and/or control information, multicast data and/or control information, and broadcast data and/or control information on the sidelink reception BWP resource of the broadcast service. Or, it is understood that the sidelink reception BWP resource of the broadcast service may support sidelink communication with a unicast transmission type, sidelink communication with a multicast transmission type, or sidelink communication with a broadcast transmission type. Or, it is understood that the sidelink reception BWP resource of the broadcast service may support sidelink communication of unicast type service, sidelink communication of multicast type service, and sidelink communication of broadcast type service.
It should be noted that the unicast type service may also be referred to as a unicast service, the multicast type service may also be referred to as a multicast service, and the broadcast type service may also be referred to as a broadcast service.
It should be noted that, if the first terminal receives multiple pieces of configuration information, and one piece of configuration information configures one type of sidelink resource, the first terminal takes the sidelink resource configured later as the standard. For example, the first terminal receives the sidelink resource of the broadcast service first, and receives the sidelink resource of the multicast service again, and then the sidelink resource of the multicast service is used as the standard. For example, if the first terminal receives the sidelink resource of the multicast service first and receives the sidelink resource of the unicast service, the sidelink resource of the unicast service is used as the standard.
It should be noted that, if the first terminal receives multiple pieces of configuration information, one piece of configuration information configures one type of sidelink resource, for example, the sidelink resource may be one or more of a sidelink resource of a broadcast service, a sidelink resource of a multicast service, and a sidelink resource of a unicast service. If the first terminal receives the sidelink resource of the unicast service, the sidelink resource of the unicast service can be used as the standard; if the side link resource of the unicast service is not received, but the side link resource of the multicast service is received, the side link resource of the multicast service can be used as the standard; if the sidelink resource of the multicast service is not received, and the sidelink resource of the unicast service is not received, the sidelink resource of the broadcast service may be used as the standard. For example, if the first terminal receives the sidelink resource of the broadcast service and receives the sidelink resource of the multicast service, the sidelink resource of the multicast service may be used as the criterion. For example, if the first terminal receives the sidelink resource of the multicast service and receives the sidelink resource of the unicast service, the sidelink resource of the unicast service may be used as the standard.
In yet another implementation, the first service type is an eMBB service, and the second service type is a URLLC service, and the sidelink reception BWP resource of the eMBB service includes a sidelink transmission resource of the URLLC service. Based on the implementation, the first configuration information configures a sidelink reception BWP resource of the eMBB service, and the sidelink reception BWP resource of the eMBB service may include a sidelink transmission resource of the URLLC service. Since other terminals, such as the second terminal, may perform the transmission of URLLC service sidelink signals on the sidelink transmission resource of the URLLC service, the first terminal may receive the sidelink signals of the URLLC service on the sidelink reception BWP resource of the eMBB service. In addition, in actual communication, since another terminal such as a third terminal can transmit the sidelink signal of the eMBB service on the sidelink transmission resource of the eMBB service, the first terminal can receive the sidelink signal of the eMBB service on the sidelink reception BWP resource of the eMBB service. Therefore, when the sidelink reception BWP resource of the eMBB service is activated, the first terminal may receive data and/or control information of the eMBB service or data and/or control information of the URLLC service on the sidelink reception BWP resource of the eMBB service. Alternatively, the sidelink reception BWP resource for the eMBB service supports sidelink communication for both URLLC services and eMBB services.
In yet another implementation, the first service type is an MTC service, the second service type is a URLLC service, and the third service type is an eMBB service, and the BWP resource received by the sidelink of the MTC service includes a sidelink transmission resource of the URLLC service, and/or a sidelink transmission resource of the eMBB service. Based on the implementation, the sidelink reception BWP resource of the MTC traffic may include a sidelink transmission resource of URLLC traffic, and/or a sidelink transmission resource of eMBB traffic. For example, when the sidelink reception BWP resource of the MTC traffic includes a sidelink transmission resource of the URLLC traffic, since other terminals, such as the second terminal, may transmit the URLLC traffic sidelink signal on the sidelink transmission resource of the URLLC traffic, the first terminal may receive the URLLC traffic sidelink signal on the sidelink reception BWP resource of the MTC traffic. In addition, in actual communication, since other terminals such as a third terminal may perform the sending of the sidelink signal of the MTC traffic on the sidelink sending resource of the MTC traffic, the first terminal may receive the sidelink signal of the MTC traffic on the sidelink receiving BWP resource of the MTC traffic. Therefore, when the sidelink receiving BWP resource of the MTC service is activated, the first terminal may receive both the data and/or control information of the MTC service and the data and/or control information of the URLLC service on the sidelink receiving BWP resource of the MTC service. Or, it is understood that the sidelink reception BWP resource of the MTC traffic supports sidelink communication of both the MTC traffic and the URLLC traffic. For another example, when the sidelink reception BWP resource of the MTC service includes a sidelink transmission resource of an eMBB service, the first terminal may receive a sidelink signal of the eMBB service on the sidelink reception BWP resource of the MTC service, since other terminals, such as the second terminal, may perform sidelink communication of the eMBB service on the sidelink transmission resource of the eMBB service. In addition, in actual communication, since other terminals, such as a third terminal, may perform the sending of the sidelink signal of the MTC service on the sidelink sending resource of the MTC service, the first terminal may receive the sidelink signal of the MTC service on the sidelink receiving BWP resource of the MTC service. Therefore, when the BWP resource is activated, the first terminal may receive the data and/or the control information of the MTC service, or the data and/or the control information of the eMBB service on the BWP resource. Or, it is understood that the sidelink reception BWP resource of the MTC service may support sidelink communication of MTC services and also support sidelink communication of eMBB services. For another example, when the BWP resource received by the sidelink of the MTC service includes a sidelink transmission resource of a URLLC service and a sidelink transmission resource of an eMBB service, since other terminals, such as the second terminal, may transmit sidelink signals of the eMBB service on the sidelink transmission resource of the eMBB service, and other terminals, such as the third terminal, may transmit URLLC service sidelink signals on the sidelink transmission resource of the URLLC service, the first terminal may receive the sidelink signals of the eMBB service and/or the URLLC service on the BWP resource received by the sidelink of the MTC service. In addition, in actual communication, since other terminals, such as the fourth terminal, may perform the sending of the sidelink signal of the MTC service on the sidelink sending resource of the MTC service, the first terminal may receive the sidelink signal of the MTC service on the sidelink receiving BWP resource of the MTC service. Therefore, when the BWP resource is activated, the first terminal may receive the data and/or control information of the MTC service, the data and/or control information of the eMBB service, and the data and/or control information of the URLLC service on the BWP resource. Or, it is understood that the sidelink receiving BWP resource of the MTC service may support sidelink communication of MTC service, also may support sidelink communication of eMBB service, and also may support sidelink communication of URLLC service.
In yet another implementation, the first service type is URLLC service, the second service type is MTC service, and the third service type is eMBB service, where the BWP resource received by the sidelink of URLLC service includes sidelink transmission resource of eMBB service and/or sidelink transmission resource of MTC service. Based on the implementation, the sidelink reception BWP resource of the URLLC service includes a sidelink transmission resource of the MTC service, and/or includes a sidelink transmission resource of the eMBB service. For example, when the sidelink reception BWP resource of the URLLC traffic includes a sidelink transmission resource of the MTC traffic, since other terminals, such as the second terminal, may perform transmission of a sidelink signal of the MTC traffic on the sidelink transmission resource of the MTC traffic, the first terminal may receive the sidelink signal of the MTC traffic on the sidelink reception BWP resource of the URLLC traffic. In addition, in actual communication, since other terminals, such as a third terminal, may perform the transmission of the sidelink signal of the URLLC service on the sidelink transmission resource of the URLLC service, the first terminal may receive the sidelink signal of the URLLC service on the sidelink reception BWP resource of the URLLC service. Therefore, when the sidelink reception BWP resource of the URLLC service is activated, the first terminal may receive both the data and/or control information of the MTC service and the data and/or control information of the URLLC service on the sidelink reception BWP resource of the URLLC service. Or, it is understood that the sidelink receiving BWP resource of the URLLC service may support sidelink communication of MTC service as well as URLLC service. For another example, when the sidelink reception BWP resource of the URLLC service includes a sidelink transmission resource of the eMBB service, since another terminal, such as the second terminal, may transmit the sidelink signal of the eMBB service on the sidelink transmission resource of the eMBB service, the first terminal may receive the sidelink signal of the eMBB service on the sidelink reception BWP resource of the URLLC service. In addition, in actual communication, since other terminals, such as a third terminal, can perform the transmission of the sidelink signal of the URLLC service on the sidelink transmission resource of the URLLC service, the first terminal can receive the sidelink signal of the URLLC service on the sidelink reception BWP resource of the URLLC service. Therefore, when the sidelink reception BWP resource of the URLLC service is activated, the first terminal may receive both the data and/or control information of the URLLC service and the data and/or control information of the eMBB service on the sidelink reception BWP resource of the URLLC service. Or, it is understood that the sidelink receiving BWP resource of the URLLC service may support sidelink communication for the eMBB service or the URLLC service. For another example, when the BWP resource for rllc service includes a BWP resource for MTC service and a BWP resource for eMBB service, the first terminal may receive the eMBB service and/or the MTC service sidelink signal on the BWP resource for rllc service, because other terminals, such as the second terminal, may transmit eMBB service sidelink signals on the BWP resource for eMBB service and other terminals, such as the third terminal, may transmit MTC service sidelink signals on the BWP resource for MTC service. In addition, in actual communication, since other terminals, such as the fourth terminal, may perform the transmission of the sidelink signal of the URLLC service on the sidelink transmission resource of the URLLC service, the first terminal may receive the sidelink signal of the URLLC service on the sidelink reception BWP resource of the URLLC service. Therefore, when the sidelink reception BWP resource of the URLLC service is activated, the first terminal may receive the data and/or control information of the MTC service, the data and/or control information of the eMBB service, and the data and/or control information of the URLLC service on the sidelink reception BWP resource of the URLLC service. Or, it is understood that the sidelink receiving BWP resource of the URLLC service may support sidelink communication of MTC service, also may support sidelink communication of eMBB service, and also may support sidelink communication of URLLC service.
It should be noted that, if the first terminal receives multiple pieces of configuration information and one piece of configuration information configures one type of sidelink resource, the first terminal takes the sidelink resource configured later as the standard, that is, the sidelink resource configured later covers the sidelink resource configured earlier. For example, the first terminal receives the sidelink resource of the URLLC service first and receives the sidelink resource of the eMBB service, and the sidelink resource of the eMBB service is used as the standard, that is, the latter can cover the former. For example, the first terminal receives the sidelink resource of the eMBB service first and receives the sidelink resource of the MTC service, the sidelink resource of the MTC service is used as the standard, that is, the former can be covered by the latter.
It should be noted that, if the first terminal receives multiple pieces of configuration information, one piece of configuration information configures one type of sidelink resource, for example, the sidelink resource may be one or more of a sidelink resource of an eMBB service, a sidelink resource of a URLLC service, and a sidelink resource of an MTC service. If the first terminal receives the sidelink resource of the MTC service, the sidelink resource of the MTC service can be used as the standard; if the sidelink resource of the MTC service is not received, but the sidelink resource of the URLLC service is received, the sidelink resource of the URLLC service can be used as a standard; if the sidelink resource of the URLLC service is not received, and the sidelink resource of the MTC service is not received, the sidelink resource of the eMBB service may be used as the standard. For example, if the first terminal receives the sidelink resource of the eMBB service and receives the sidelink resource of the URLLC service, the sidelink resource of the URLLC service may be used as the reference. For example, if the first terminal receives the sidelink resource of the URLLC service and receives the sidelink resource of the MTC service, the sidelink resource of the MTC service may be used as the reference.
It should be noted that, for the third implementation method, in a specific implementation, the configuration information of the sidelink receiving BWP resource of the first traffic type may include an identifier of a sidelink transmission resource of the second traffic type, and/or an identifier of a sidelink transmission resource of the third traffic type.
For example, there are 4 sidelink transmission resources of the second service type, and the identifiers are resource 1, resource 2, resource 3, and resource 4, respectively. If the sidelink reception BWP resource of the first traffic type includes sidelink transmission resource 1 and sidelink transmission resource 2 of the second traffic type, the identification of the sidelink transmission resource of the second traffic type, that is, resource 1 and resource 2, may be included in the configuration information of the sidelink reception BWP resource of the first traffic type.
For example, there are 4 sidelink transmission resources of the third service type, and the identifiers are resource 5, resource 6, resource 7, and resource 8, respectively. If the sidelink reception BWP resource of the first traffic type includes a sidelink transmission resource 7 and a sidelink transmission resource 8 of the third traffic type, the identification of the sidelink transmission resource of the third traffic type, that is, the resource 7 and the resource 8, may be included in the configuration information of the sidelink reception BWP resource of the first traffic type.
By the above configuration, the configuration information of the first transmission type sidelink receiving BWP resource includes an identifier of a sidelink transmitting resource of the second transmission type, such as a resource pool identifier, or a transmitting BWP identifier, and/or the configuration information of the first transmission type sidelink receiving BWP resource includes an identifier of a sidelink transmitting resource of the third transmission type, such as a resource pool identifier, or a transmitting BWP identifier. The terminal and/or the network device may be understood as: when the configuration information of the receiving BWP includes the identifier of the sidelink transmission resource, the sidelink transmission resource corresponding to the identifier of the sidelink transmission resource (here, "transmitting" is with respect to the second terminal and/or the third terminal) is the sidelink reception resource of the first terminal, and the first terminal may receive the sidelink signal in the sidelink reception resource.
Based on the first implementation method, the second implementation method, or the third implementation method, multiple service types can be simultaneously supported on one sidelink BWP receiving resource, for example, a broadcast service and a unicast service are simultaneously supported, or a broadcast service and a multicast service are simultaneously supported, or a unicast service, a multicast service, and a broadcast service are simultaneously supported. For another example, the method supports the URLLC service and the MTC service simultaneously, or supports the URLLC service and the eMBB service simultaneously, or supports the MTC service, the eMBB service and the URLLC service simultaneously.

In this implementation, the embodiment shown in fig. 3 is then the same as the embodiment shown in fig. 2.
In yet another possible implementation, the first sidelink BWP resource may include a sidelink transmit resource pool and/or a sidelink receive resource pool. I.e. the first sidelink BWP resource is not further divided into sidelink sending BWP resource and sidelink receiving BWP resource.
Based on the above steps 201-202, the first side link BWP resource is configured to the first terminal through the first configuration information, so that the first terminal can send control information and/or data to the second terminal on the first side link BWP resource, and the first terminal can also receive the control information and/or data sent by the second terminal or other terminals on the first side link BWP resource. Therefore, the configuration of the side link resources for the terminal is realized. That is to say, all the implementations of the above steps 201 to 202 and the details thereof can be applied to the embodiment of fig. 3.
Optionally, all the implementations of steps 301 to 302 and the details thereof may be applied to the embodiment of fig. 2.
Optionally, the first configuration information in the embodiment of fig. 3 may be the same configuration information as the first configuration information in the embodiment of fig. 2, or may also be configuration information different from the first configuration information in the embodiment of fig. 2, or the first configuration information in the embodiment of fig. 3 and the first configuration information in the embodiment of fig. 2 may be in different configuration manners, or different signaling in the same configuration manner, or different information contents in the same signaling.
For the embodiment shown in fig. 3, different configurations of sidelink resources are given below.

Based on the first configuration mode, a network device, such as a network management system, may configure a first BWP resource for a first terminal in a pre-configured manner, where the first BWP resource includes a resource pool, and the resource pool may include, for example, a sending resource pool and/or a receiving resource pool. The transmission resource pool may be used for the terminal to transmit control information and/or data, and the reception resource pool may be used for the terminal to receive control information and/or data. Based on the configuration mode, the first terminal is configured with the sidelink resource through the BWP resource.

The sending resource pool may be used for the terminal to send control information and/or data, and the receiving resource pool may be used for the terminal to receive control information and/or data. Based on the configuration mode, the first terminal is configured with the sidelink resource in the form of BWP resource.
In yet another implementation, the sidelink resources configured by the second configuration information include a resource pool (herein, the resource pool may be referred to as a third resource pool, for example), where the third resource pool is determined according to the first sidelink BWP resources configured by the first configuration information. Or, it is understood that, instead of configuring the first terminal with the sidelink resource in the form of a BWP resource, the second configuration information configures the sidelink resource for the first terminal in the form of a resource pool, and the configured resource pool is derived from the first sidelink BWP resource.
Optionally, the BWP resource may be configured in a form, that is, the terminal may receive the BWP resource configured in different configuration modes. The configuration of the BWP resources in a plurality of flexible configuration modes can be realized.
Optionally, through the configuration in the form of the resource pool, it may be avoided that multiple BWP resources are configured in different configuration manners, for example, only one BWP resource may be configured, and when the resource is configured in a subsequent configuration manner, the resource pool may be further configured in the BWP resource, which may simplify the processing complexity of the network device and the terminal.
Optionally, a first bypass BWP identifier may be included in the configuration information of the resource pool, that is, the resource location of the resource pool may be determined according to the bandwidth resource corresponding to the first bypass BWP identifier. The specific frequency domain resource of the resource pool may be a partial resource of the bandwidth resource corresponding to the first bypass BWP identifier.
Based on the first configuration mode, after receiving the second configuration information or when receiving the second configuration information, the first terminal may optionally receive third configuration information, where a configuration mode corresponding to the third configuration information is RRC dedicated information configuration.
In one implementation, the sidelink resource configured by the third configuration information includes a third sidelink BWP resource, and the sidelink resource configured by the third sidelink BWP resource includes a resource pool (the resource pool may be referred to as a fourth resource pool, for example), which may include a sending resource pool and/or a receiving resource pool, for example. The sending resource pool may be used for the terminal to send control information or data, and the receiving resource pool may be used for the terminal to receive control information or data. Based on the configuration mode, the first terminal is configured with the sidelink resource in the form of BWP resource.
In yet another implementation, the third configuration information includes a fifth resource pool, wherein the fifth resource pool is determined according to the first sidelink BWP resource configured by the first configuration information. Or, it is understood that, instead of configuring the sidelink resource for the first terminal in the form of a BWP resource, the third configuration information configures the sidelink resource for the first terminal in the form of a resource pool, and the configured resource pool is obtained from the first sidelink BWP resource.
Optionally, a first bypass BWP identifier may be included in the configuration information of the resource pool, that is, the resource location of the resource pool may be determined according to the bandwidth resource corresponding to the first bypass BWP identifier. The frequency domain resource of the resource pool may be a partial resource of the bandwidth resource corresponding to the first side link BWP identifier.
In yet another implementation, the third configuration information includes a sixth resource pool, wherein the sixth resource pool is determined according to the second sidelink BWP resource configured by the second configuration information. Or, it is understood that, instead of configuring the first terminal with the sidelink resource in the form of a BWP resource, the third configuration information configures the sidelink resource for the first terminal in the form of a resource pool, and the configured resource pool is derived from the second sidelink BWP resource.
Optionally, a second sidelink BWP identifier may be included in the configuration information of the resource pool, that is, the resource location of the resource pool may be determined according to the bandwidth resource corresponding to the second sidelink BWP identifier. The frequency domain resource of the resource pool may be a partial resource of the bandwidth resource corresponding to the BWP identifier of the second sidelink.
In yet another implementation, the third configuration information includes a fifth resource pool determined according to the first sidelink BWP resource configured by the first configuration information and a sixth resource pool determined according to the second sidelink BWP resource configured by the second configuration information. Or, it is understood that, instead of configuring the sidelink resource for the first terminal in the form of a BWP resource, the third configuration information configures the sidelink resource for the first terminal in the form of a resource pool, and the configured resource pool is obtained from the first sidelink BWP resource and the second sidelink BWP resource.
Optionally, a first sidelink BWP identifier or a second sidelink BWP identifier may be included in the configuration information of the resource pool, that is, the resource location of the resource pool may be determined according to the bandwidth resource corresponding to the first sidelink BWP identifier or according to the bandwidth resource corresponding to the second sidelink BWP identifier. The specific frequency-domain resource of the resource pool may be a partial resource of the bandwidth resource corresponding to the first sidelink BWP identifier or a partial resource of the bandwidth resource corresponding to the second sidelink BWP identifier.
A second configuration mode, where the configuration mode corresponding to the first configuration information in step 301 is system information configuration or RRC common information configuration, and the first bypass BWP resource includes a resource pool (the resource pool may be referred to as a seventh resource pool, for example).
Based on the second configuration mode, a network device, such as an access network device, may configure a first sidelink BWP resource for the first terminal in a system information configuration or RRC common information configuration manner, where the first sidelink BWP resource includes a resource pool, and the resource pool may include, for example, a transmission resource pool and/or a reception resource pool. The sending resource pool may be used for the terminal to send control information or data, and the receiving resource pool may be used for the terminal to receive control information or data. Based on the configuration mode, the first terminal is configured with the sidelink resource through the BWP resource.
Based on the second configuration mode, after receiving the first configuration information or when receiving the first configuration information, the first terminal may further receive fourth configuration information, where a configuration mode corresponding to the fourth configuration information is RRC dedicated information configuration.
In one implementation, the sidelink resource configured by the fourth configuration information includes a fourth sidelink BWP resource and the fourth sidelink BWP resource includes a resource pool (the resource pool herein may be referred to as an eighth resource pool, for example), which may include a transmitting resource pool and/or a receiving resource pool, for example. The sending resource pool may be used for the terminal to send control information or data, and the receiving resource pool may be used for the terminal to receive control information or data. Based on the configuration mode, the first terminal is configured with the sidelink resource through the BWP resource.
In yet another implementation, the sidelink resource configured by the fourth configuration information includes a resource pool (herein, the resource pool may be referred to as a ninth resource pool, for example), where the ninth resource pool is determined according to the first sidelink BWP resource configured by the first configuration information. Or, it is understood that, instead of configuring the sidelink resource for the first terminal in the form of a BWP resource, the fourth configuration information configures the sidelink resource for the first terminal in the form of a resource pool, and the configured resource pool is obtained from the first sidelink BWP resource.
Optionally, a first bypass BWP identifier may be included in the configuration information of the resource pool, that is, the resource location of the resource pool may be determined according to the bandwidth resource corresponding to the first bypass BWP identifier. The specific frequency domain resource of the resource pool may be a partial resource of the bandwidth resource corresponding to the first bypass BWP identifier.
Based on the above configuration mode, it is implemented to configure the sidelink resource for the first terminal, and specifically, configure the sidelink BWP resource for the first terminal, which may be configured in the form of BWP resource or in the form of resource pool.
