Description

Resource status confirmation method, device, system and storage medium

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on October 31, 2023, with application number 202311444356.X and invention name “Resource Status Confirmation Method, Device, System and Storage Medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a resource status confirmation method, device, system and storage medium. Background Art

[0003] The sending / receiving of sidelink-positioning reference signal (SL-PRS) between terminals can be carried out on a dedicated resource pool. When sending SL-PRS on a dedicated resource pool, there are two modes of resource allocation, wherein the resources allocated in mode 1 may include dynamic grant (DG) resources and configured grant (CG) resources dynamically scheduled by network equipment. Among them, the configured grant resources may include two types: configured grant type 1 (CG type1) and configured grant type 2 (CG type2). Among them, CG type2 means that the configuration grant requires the activation or deactivation of the SL-PRS resource grant provided by the physical downlink control channel (PDCCH). When the PDCCH activates the CGtype2 resource, the sending terminal stores the SL-PRS resource grant; when the PDCCH deactivates the CGtype2 resource, the sending terminal clears the stored SL-PRS resource grant.

[0004] However, when PDCCH activates the CGtype2 resource, but the terminal does not receive the PDCCH, or receives the PDCCH but does not provide feedback, the network device believes that the CGtype2 resource has been activated, but the terminal believes that it has not been activated. The network device will reserve the CGtype2 resource, but in fact the terminal will not send on the CGtype2 resource, resulting in a waste of resources.

[0005] Currently, there is a technology that feeds back the status of CGtype2 resources used for sidelink (SL) communication through a medium access control-control element (MAC-CE).

[0006] Therefore, how to confirm the status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool is a problem that needs to be solved.

[0068] The solution of this application is further described below with reference to the accompanying drawings.

[0069] Figure 1 shows a possible, non-limiting system diagram. As shown in Figure 1 , communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. Communication system 1000 may also include the Internet 300. RAN 100 includes at least one RAN node (e.g., 110a and 110b in Figure 1 , collectively referred to as 110) and at least one terminal (e.g., 120a-120j in Figure 1 , collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in Figure 1). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wiredly connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 may be separate physical devices, or they may be a single physical device that integrates core network logical functions and radio access network logical functions.

[0070] The RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a 4G or 5G mobile communication system, or a future-oriented evolutionary system (such as a 6G mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0071] RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and facilitates wireless access for terminals. Multiple RAN nodes 110 in communication system 1000 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminal 120j accessing RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.

[0072] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (such as 110a in Figure 1 ), a micro base station or an indoor station (such as 110b in Figure 1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Alternatively, a RAN node may be a server, a wearable device, a vehicle, or an onboard device. For example, the access network device in vehicle-to-everything (V2X) technology may be a roadside unit (RSU).

[0073] In another possible scenario, multiple RAN nodes assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a centralized unit-control plane (CU-CP), a centralized unit-user plane (CU-UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0074] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called an open-centralized unit (open-CU, O-CU), DU may also be called an open-distributed unit (open-distributed unit, O-DU), CU-CP may also be called an open-centralized unit-control plane (open-central unit-control plane, O-CU-CP), CU-UP may also be called an open-centralized unit-user plane (open-central unit-user plane, O-CU-UP), and RU may also be called an open-radio unit (open-radio unit, O-RU). For convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0075] A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal may be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.

[0076] The communication between the access network device and the terminal device follows a certain protocol layer structure. The protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, or a physical (PHY) layer. The user plane protocol layer may include at least one of the following: a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer.

[0077] For the network elements in the ORAN system and the corresponding protocol layer functions that can be implemented, please refer to the following Table 1:

[0078] Table 1

[0079] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0080] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal functionality.

[0081] In the embodiments of the present application, a base station is also referred to as an access network device. The device used to implement the functions of the access network device can be the access network device; it can also be a device that can support the access network device in implementing the functions, such as a chip system, a hardware circuit, a software module, or a hardware circuit and a software module. The device can be installed in the access network device or used in conjunction with the access network device. In the embodiments of the present application, only the device used to implement the functions of the access network device is used as an example, and the embodiments of the present application are not limited to the solutions of the embodiments of the present application.

[0082] It can be understood that the present application can be applied between access network equipment and terminals.

[0083] It should be understood that the number and type of each device in the communication system shown in Figure 1 are for illustration only, and the present application is not limited to this. In actual applications, the communication system may also include more terminals, more access network devices, and other network elements, such as core network devices, and / or network elements for implementing artificial intelligence functions.

[0084] It is understandable that all or part of the functions implemented by one or more of the terminals, access network devices, core network devices, or network elements for implementing artificial intelligence functions can be virtualized, that is, implemented by one or more of the proprietary processors or general-purpose processors and the corresponding software modules. Among them, since the terminal and the access network device involve an interface for air interface transmission, the transceiver function of the interface can be implemented by hardware. Core network equipment, such as operation administration and maintenance (OAM) network elements, can be virtualized. Optionally, one or more functions of the virtualized terminal, access network device, core network device, or network elements for implementing artificial intelligence functions can be implemented by cloud devices, such as cloud devices in an over the top (OTT) system.

[0085] Sidelink communication refers to terminal A sending the physical sidelink control channel (PSCCH) and the physical sidelink shared channel (PSSCH) and the demodulation reference signal (DMRS) for demodulating the corresponding channel on the resource pool. There is no SL-PRS transmission on this resource pool. During the sidelink communication process, terminal A sends PSCCH and PSSCH to terminal B. At the same time, terminal A may also send SL-PRS. The resource pool that can be used to send PSSCH and SL-PRS is called a shared resource pool, which means that the terminal can send PSSCH and SL-PRS on the same resource pool. As shown in Figure 2, a sidelink channel and signal mapping diagram of an example embodiment of the present application is shown. Taking 14 orthogonal frequency division multiplexing (OFDM) symbols in a time slot as an example, a resource mapping diagram for sending PSCCH, PSSCH, DMRS, and SL-PRS is illustrated. The PSCCH carries the first-level sidelink control information (SCI), SCI 1-A, which is used to schedule the PSSCH and the second-level SCI carried on the PSSCH. Both the first-level SCI and the second-level SCI are sidelink control information, containing complete control information for scheduling the PSSCH and the SL-PRS. DMRS is a demodulation reference signal used to demodulate data. SL-PRS is a positioning reference signal sent by terminal A.

[0086] In addition, the sending / receiving of SL-PRS between terminals can also be sent only on a dedicated resource pool. As shown in Figure 3, it is a schematic diagram of an SL-PRS dedicated resource pool as an example of an embodiment of the present application. Taking 14 OFDM symbols in a time slot as an example, the figure illustrates the resource mapping of PSCCH and SL-PRS transmission on a dedicated resource pool. Among them, the PSCCH channel carries the first-level SCI information SCI 1-B, which is used to schedule SL-PRS transmission. The first-level SCI belongs to the sidelink control information, which contains complete control information for scheduling SL-PRS.

[0087] This application mainly relates to transmitting SL-PRS on a dedicated resource pool.

[0088] When the SL-PRS is sent on a dedicated resource pool, there are two modes for resource allocation.

[0089] Mode 1: The resources for sending SL-PRS may be resources dynamically scheduled (dynamic grant, DG) by the access network device, or resources configured for grant (configured grant, CG).

[0090] Mode 2: The terminal autonomously determines the sending resources. Specifically, the upper layer (MAC / RRC layer) within the terminal requests the terminal to determine a resource set, and the upper layer selects resources from the resource set to send SL-PRS.

[0091] For resource allocation mode 1, the configuration of authorized resource CG includes two types:

[0092] Configuration authorization type 1 (CGtype1): The SL-PRS resource authorization is provided by the access network device to the sending terminal through dedicated signaling RRC. After receiving the configuration information, the sending terminal stores the SL-PRS resource authorization. When it needs to send SL-PRS, it directly uses the configured authorized resources to send SL-PRS.

[0093] Configuration Grant Type 2 (CGtype2): SL-PRS resource grants are activated or deactivated by the physical downlink control channel (PDCCH). When the PDCCH activates CGtype2 resources, the transmitting terminal stores the SL-PRS resource grants. When the PDCCH deactivates CGtype2 resources, the transmitting terminal clears the stored SL-PRS resource grants.

[0094] For CGtype1, the resource configuration provided by the access network equipment includes at least: resource pool index, CG index, CG period, time domain resource location, reference system frame number (SFN) in the time domain used to determine the resource time domain offset, time offset relative to the reference system frame number, SL-PRS resource identifier (ID), number of SL-PRS symbols, SL-PRS density in the frequency domain, and SL-PRS offset in the frequency domain.

[0095] For CGtype2, the resource configuration provided by the access network equipment includes at least: the CG index, the CG period, the SL-PRS resource identifier (ID), the number of SL-PRS symbols, the SL-PRS density in the frequency domain, and the SL-PRS offset in the frequency domain. The downlink control information DCI3_2 for scheduling SL-PRS resources is used to activate or deactivate CGtype2.

[0096] For CGtype2, when the downlink control information DCI3_2 is used to activate or deactivate SL-PRS CGtype2, if the terminal does not receive the PDCCH carrying DCI 3_2, or receives the PDCCH but does not feedback the acknowledgement (ACK) information of the correct receipt of the PDCCH to the access network device, the access network device cannot determine whether the terminal has correctly received the PDCCH, and thus cannot determine whether the SL-PRS CGtype2 is activated or deactivated. If the access network device believes that CGtype2 has been activated, but the terminal believes that it has not been activated, the access network device will reserve the resources corresponding to CGtype2, but the terminal will not send on the CGtype2 resources in time, resulting in a waste of resources.

[0097] Currently, there is no technology on how to provide feedback on the status of CG type 2.

[0098] For sidelink communications, including the transmission of PSCCH and PSSCH channels, there are also two modes of resource allocation.

[0099] Mode 1: The resources for sidelink communication may be resources dynamically scheduled by the access network device or configured authorized resources.

[0100] Mode 2: The terminal autonomously determines the transmission resources. Specifically, the upper layer within the terminal requests the terminal to determine a resource set, and the upper layer selects resources from the resource set for sidelink communication.

[0101] For resource allocation mode 1, configuring authorized resources includes two types:

[0102] CGtype1: The sidelink resource authorization is provided by the access network device to the sending terminal through the dedicated signaling RRC. After receiving the configuration information, the sending terminal stores the sidelink resource authorization. When sidelink communication is required, it directly uses the configured authorized resources for sidelink communication.

[0103] CGtype2: The sidelink resource authorization is activated or deactivated by PDCCH. When PDCCH activates the CGtype2 resource, the sending terminal stores the sidelink resource authorization; when PDCCH deactivates the CGtype2 resource, the sending terminal clears the stored sidelink resource authorization.

[0104] If the terminal receives PDCCH carrying downlink control information DCI 3_0 indicating a CGtype2 resource deactivation, the MAC entity of the sending terminal triggers the deactivation confirmation of the CGtype2 resource. After the terminal sends the media access control control element (MAC-CE) for the CGtype2 resource deactivation confirmation, the MAC entity clears the stored CGtype2 resource. Or, if the terminal receives PDCCH carrying downlink control information DCI 3_0 indicating a CGtype2 resource activation, the MAC entity of the sending terminal triggers the confirmation of the CGtype2 resource and stores the CGtype2 resource. The terminal sends the confirmation MAC-CE for the CGtype2 resource activation.

[0105] As shown in Figure 4, it is a schematic diagram of the format of a MAC-CE. The MAC header in the MAC-CE includes a special extended logical channel identifier (eLCID), which is used to associate the confirmation of the CG type 2 resource in the above side link communication scenario. Among them, the MAC-CE includes 8 fields (C i ), the C i The definition is as follows: If the terminal is configured with CGType2 and the index of the configured CG sl-ConfigIndexCG is i, then this field C i Indicates the activation or deactivation status of the CGType2 resource with index sl-ConfigIndexCG i. Otherwise, if the index sl-ConfigIndexCG of the configured CGType2 resource does not have i, then C i Ignored. When C i When set to 1, it indicates that the CGType2 resource corresponding to index sl-ConfigIndexCG i is confirmed to be activated. i When set to 0, it indicates that the CGType2 resource corresponding to index sl-ConfigIndexCG i is confirmed to be deactivated.

[0106] However, the above MAC-CE can only be used to confirm the activation or deactivation status of the CGType2 resources configured for sidelink communication, and cannot be used to confirm the activation or deactivation status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool. Or it is impossible to confirm both the activation or deactivation status of the CGType2 resources configured for sidelink communication and the activation or deactivation status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool.

[0107] In view of this, it is necessary to confirm the activation or deactivation status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool. Furthermore, it is possible to confirm the activation or deactivation status of the CGType2 resources configured for the sidelink communication, as well as the activation or deactivation status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool.

[0108] To solve the above problems, multiple embodiments are described below:

[0109] As shown in Figure 5, a flow chart of a resource status confirmation method provided in an embodiment of the present application is provided. Exemplarily, the method may include the following steps:

[0110] S501. An access network device sends downlink control information (DCI) to a terminal. Correspondingly, the terminal receives the downlink control information.

[0111] In this embodiment, the terminal is configured with at least one second configuration authorized resource. The at least one second configuration authorized resource is used to send the SL-PRS. The at least one second configuration authorized resource belongs to a resource in a dedicated resource pool for transmitting the SL-PRS.

[0112] The at least one second configured authorized resource is a CG type 2 resource. When the access network device schedules a configured authorized resource among the at least one second configured authorized resource to transmit an SL-PRS, the access network device may send downlink control information to the terminal, where the downlink control information is used to activate the first configured authorized resource. The first configured authorized resource is any one or more resources among the at least one second configured authorized resource. In addition, when the first configured authorized resource is to be released, the access network device may send downlink control information to the terminal, where the downlink control information is used to deactivate the first configured authorized resource.

[0113] Furthermore, the downlink control information includes an index of the first configuration authorization resource. Each configuration authorization resource has a unique index.

[0114] Exemplarily, the above downlink control information may be sent by the O-DU or the O-RU.

[0115] Exemplarily, the downlink control information is DCI3_2. The access network device may configure eight configuration authorization resources C1 to C8 for the terminal.

[0116] S502. In response to the downlink control information, the terminal sends first information to the access network device. Correspondingly, the access network device receives the first information.

[0117] Exemplarily, the first information may be received by the O-CU-CP.

[0118] After receiving the downlink control information, the terminal needs to provide feedback to the access network device regarding the status of the at least one second configuration authorization resource. Exemplarily, the status of each of the at least one second configuration authorization resource is provided to the access network device. This status includes an activated state and an inactivated state. Therefore, the terminal sends first information to the access network device. The first information indicates the status of the at least one configured second configuration authorization resource.

[0119] In addition, the method may further include: the terminal receiving DCI3_0 sent by the access network device, the DCI3_0 being used to activate or deactivate a fourth configuration authorization resource, the fourth configuration authorization resource being any one of the at least one third configuration authorization resource. The terminal sending second information to the access network device.

[0120] The first information includes a first identifier. The first identifier is different from a second identifier in the second information. The second information is used to indicate a status of at least one configured third configuration authorization resource, where the at least one third configuration authorization resource is used to send a PSCCH and / or a PSSCH, that is, the at least one third configuration authorization resource is used for sidelink communication.

[0121] By making the first identifier in the first information different from the second identifier in the second information, after the access network device receives the first information and the second information, it can distinguish whether the received information is the first information or the second information based on the first identifier and the second identifier, thereby distinguishing whether the received information is used to confirm the status of the CGType2 resource for sending SL-PRS, or the status of the CGType2 resource for confirming the side link communication configuration.

[0122] Exemplarily, the first information is a first MAC-CE, which is used to indicate the status of at least one second configuration authorization resource being configured. The format of the first MAC-CE can be referred to in FIG4 , which is the same as the format of the MAC-CE used to confirm the status of the CGType2 resource configured for the sidelink communication. The first MAC-CE includes 8 fields (C i ), the C i The definition is as follows:

[0123] If the terminal is configured with SL-PRS CGType2 and the index of the configured CG sl-PRS-ConfigIndexCG is i, then this field C iIndicates the activation or deactivation status of the SL-PRS CGType2 resource with index sl-PRS-ConfigIndexCG as i. Otherwise, if the configured SL-PRS CGType2 resource index sl-PRS-ConfigIndexCG does not have i, then C i Ignored. When C i When set to 1, it indicates that the SL-PRS CGType2 resource corresponding to index sl-PRS-ConfigIndexCG i is confirmed to be activated. i When set to 0, it indicates that the SL-PRS CGType2 resource corresponding to the index sl-PRS-ConfigIndexCG i is confirmed to be deactivated.

[0124] The first identifier is the first eLCID number, which is located at the beginning of the first MAC-CE. For example, the first eLCID code point is 253, and the corresponding index value is 317.

[0125] For example, if the terminal receives DCI 3_2 carried by PDCCH, indicating deactivation of an SL-PRS CGType2 resource, the MAC entity of the sending terminal triggers deactivation confirmation of the SL-PRS CGType2 resource. After the terminal sends MAC-CE for confirmation of deactivation of the SL-PRS CG Type2 resource, the MAC entity clears the stored SL-PRS CGType2 resource; or, if the terminal receives DCI 3_2 carried by PDCCH, indicating activation of an SL-PRS CGType2 resource, the MAC entity of the sending terminal triggers confirmation of the SL-PRS CGType2 resource and stores the SL-PRS CGType2 resource, and the terminal sends MAC-CE for confirmation of activation of the SL-PRS CGType2 resource.

[0126] The second information is a second MAC-CE, which is used to indicate the status of at least one configured third configuration authorization resource. The second information is used to respond to DCI3_0. The status includes an active state and an inactive state. The second identifier is a second eLCID number, which is located in the header of the second MAC-CE.

[0127] Verify the status of SL-PRS CGType2 resources on a dedicated SL-PRS resource pool without affecting the status of sidelink CG Type2 resources. It is also possible to verify the status of SL-PRS CGType2 resources and sidelink CG Type2 resources simultaneously, with the two verifications being independent. The index of the SL-PRS CGType2 resource and the index of the sidelink CG Type2 resource can be the same or different. The index configuration of the two resources is also independent.

[0128] According to a resource status confirmation method provided by an embodiment of the present application, when the terminal receives downlink control information sent by the access network device for activating or deactivating a first configuration authorization resource, the terminal sends first information to the access network device to indicate the status of at least one second configuration authorization resource configured. The first identifier included in the first information is different from the second identifier in the second information used to confirm the status of the CGType2 resource configured for the side link communication, thereby realizing the confirmation of the status of the CGType2 resource used to send SL-PRS, and does not conflict with the second information.

[0129] In another embodiment, a communication method is provided, comprising the following steps: an access network device sends first downlink control information to a terminal. Accordingly, the terminal receives the first downlink control information. Exemplarily, the first downlink control information may be DCI3_2. The terminal is configured with at least one second configuration authorization resource. The at least one second configuration authorization resource is used to send an SL-PRS. The at least one second configuration authorization resource belongs to a resource in a dedicated resource pool for transmitting an SL-PRS. The first downlink control information is used to activate the first configuration authorization resource. The first configuration authorization resource is any one or more resources among the at least one second configuration authorization resource. The access network device sends second downlink control information to the terminal. Accordingly, the terminal receives the second downlink control information. Exemplarily, the second downlink control information may be DCI3_0. The second downlink control information is used to activate or deactivate a fourth configuration authorization resource, which is any one of the at least one third configuration authorization resource. The first information includes a first identifier. The first identifier is different from the second identifier in the second information. The second information is used to indicate the status of at least one configured third configuration authorization resource. The at least one third configuration authorization resource is used to send PSCCH and / or PSSCH, that is, the at least one third configuration authorization resource is used for sidelink communication. The terminal sends the first information to the access network device in response to the above-mentioned first downlink control information. Accordingly, the access network device receives the first information. The first information is used to indicate the status of at least one configured second configuration authorization resource. The terminal sends the second information to the access network device in response to the above-mentioned second downlink control information. Accordingly, the access network device receives the second information. The second information is used to indicate the status of at least one configured third configuration authorization resource. It can be understood that this embodiment does not limit the transmission order of the first downlink control information and the second downlink control information, nor does it limit the transmission order of the first information and the second information.

[0130] The above embodiment describes how to confirm the status of the CGType2 resources configured for sidelink communication by using the first eLCID number in the newly defined first MAC-CE header, and the first MAC-CE does not conflict with the second MAC-CE used to confirm the status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool.

[0131] The following embodiments will describe the use of the existing MAC-CE for confirming the status of CGType2 resources of SL-PRS in the SL-PRS dedicated resource pool, while also confirming the status of CGType2 resources configured for sidelink communication.

[0132] As shown in Figure 6, it is a flowchart of another resource status confirmation method provided by an embodiment of the present application. Exemplarily, the method may include the following steps:

[0133] S601. The access network device sends downlink control information to the terminal. Correspondingly, the terminal receives the downlink control information.

[0134] Exemplarily, the downlink control information may be sent by the O-DU or the O-RU.

[0135] In this embodiment, the terminal is configured with at least one second configuration authorized resource. The at least one second configuration authorized resource is used to send the SL-PRS. The at least one second configuration authorized resource belongs to a resource in a dedicated resource pool for transmitting the SL-PRS.

[0136] The terminal is further configured with at least one third configured grant resource. The at least one third configured grant resource is used to send a PSCCH and / or a PSSCH, that is, the at least one third configured grant resource is used for sidelink communication.

[0137] The index of at least one second configuration authorization resource is different from the index of at least one third configuration authorization resource.

[0138] The at least one second configuration authorization resource and the at least one third configuration authorization resource are CG type 2 resources. When the access network device schedules a configuration authorization resource among the at least one second configuration authorization resource to transmit an SL-PRS, or schedules a configuration authorization resource among the at least one third configuration authorization resource for sidelink communication, the access network device may send downlink control information to the terminal, where the downlink control information is used to activate the first configuration authorization resource. The first configuration authorization resource is any one or more of the at least one second configuration authorization resource or the at least one third configuration authorization resource. In addition, when the first configuration authorization resource is to be released, the access network device may send downlink control information to the terminal, where the downlink control information is used to deactivate the first configuration authorization resource.

[0139] Furthermore, the downlink control information includes an index of the first configuration authorization resource. Each configuration authorization resource has a unique index.

[0140] S602. In response to the downlink control information, the terminal sends first information to the access network device. Correspondingly, the access network device receives the first information.

[0141] Exemplarily, the first information may be received by the O-DU or the O-RU.

[0142] After receiving the above-mentioned downlink control information, the terminal needs to feedback the status of the above-mentioned at least one second configuration authorization resource to the access network device. Therefore, the terminal sends the first information to the access network device. In this embodiment, the first information reuses the existing feedback information for confirming the status of the CGType2 resource configured for the side link communication. Therefore, the first information is used to indicate the status of the configured at least one second configuration authorization resource and / or at least one third configuration authorization resource. The index of the at least one second configuration authorization resource is different from the index of the at least one third configuration authorization resource.

[0143] By setting the index of at least one second configuration authorization resource to be different from the index of at least one third configuration authorization resource, when the access network device receives the above-mentioned first information, it can determine which resource the status of any one of the feedback resources corresponds to based on the index of the resource, thereby knowing the status of the CGType2 resource used to confirm the transmission of SL-PRS, and the status of the CGType2 resource used for side link communication configuration.

[0144] Exemplarily, the above-mentioned first information is MAC-CE, and the format of the MAC-CE can be referred to Figure 4. The MAC-CE includes a first field and / or a second field, the first field is used to indicate the status of at least one second configuration authorization resource, and the second field is used to indicate the status of at least one third configuration authorization resource. The status includes an activated state and an inactivated state. The sum of the number of the above-mentioned at least one second configuration authorization resource and at least one third configuration authorization resource is less than or equal to the first threshold. For example, the first threshold may be 8. For example, C1 to C4 of the MAC-CE correspond to the status of the CGType2 resource for transmitting SL-PRS, and C5 to C8 correspond to the status of the CGType2 resource for the sidelink communication configuration.

[0145] For example, in the SL-PRS dedicated resource pool, in the resource allocation mode, if the terminal is configured with a CGType2 resource index of sl-PRS-ConfigIndexCG for transmitting SL-PRS. The CGType2 resource index of sl-ConfigIndexCG is configured for sidelink communication in the sidelink communication resource pool. For the same terminal, the total number of CGType2 configuration sets for the configured SL-PRS and the number of CGType2 resource configuration sets for sidelink communication shall not exceed 8, and the index of the configured CGType2 of the SL-PRS is different from the index of the CGType2 resource for sidelink communication. The access network device does not configure the CGType2 index of the SL-PRS to be the same as the index value of the CGType2 for sidelink communication.

[0146] If the terminal receives DCI 3_2 carried by PDCCH, indicating deactivation of an SL-PRS CGType2 resource; or receives DCI 3_0 carried by PDCCH, indicating deactivation of a sidelink CGType2 resource, the MAC entity of the sending terminal triggers deactivation confirmation of the SL-PRS CGType2 resource in response to DCI 3_2 or the sidelink CGType2 resource in response to DCI 3_0. After the terminal sends a MAC-CE for deactivation confirmation of the SL-PRS CG Type2 resource and / or the sidelink CGType2 resource, the MAC entity clears the stored SL-PRS CGType2 resource and / or the sidelink CGType2 resource. Alternatively, if the terminal receives DCI 3_2 carried by the PDCCH indicating activation of an SL-PRS CGType2 resource, or receives DCI 3_0 carried by the PDCCH indicating activation of a sidelink CGType2 resource, the MAC entity of the sending terminal triggers confirmation of the SL-PRS CGType2 resource and / or the sidelink CGType2 resource, and stores the SL-PRS CGType2 resource or the sidelink CGType2 resource, and the terminal sends a confirmation MAC-CE for activation of the SL-PRS CGType2 resource and / or the sidelink CGType2 resource. Specifically, when DCI 3_0 is received, before receiving DCI 3_2, the terminal has not sent a confirmation message in response to 3_0. After receiving DCI 3_2, the terminal sends a confirmation message MAC-CE in response to DCI 3_0 and DCI 3_2, and the MAC-CE includes confirmation of the SL-PRS CGType2 resource and the sidelink CGType2 resource. Alternatively, when receiving DCI 3_2, the terminal has not sent a confirmation message in response to 3_2 before receiving DCI3_0. After receiving DCI3_0, the terminal sends a confirmation message MAC-CE in response to DCI 3_0 and DCI 3_2, which includes confirmation of SL-PRS CGType2 resources and sidelinkCGType2 resources.

[0147] Therefore, the same confirmation MAC-CE can be used to confirm the status of the SL-PRS CG Type 2 resource, or to simultaneously confirm the status of the SL-PRS CG Type 2 resource and the sidelink CG Type 2 resource.

[0148] According to a resource status confirmation method provided in an embodiment of the present application, by setting the index of the CGType2 resource configured for side link communication to be different from the index of the CGType2 resource of the SL-PRS in the SL-PRS dedicated resource pool, it is possible to confirm the status of the CGType2 resource configured for side link communication and the status of the CGType2 resource of the SL-PRS in the SL-PRS dedicated resource pool through one information.

[0149] The above embodiment describes that by setting the index of the CGType2 resource configured for sidelink communication to be different from the index of the CGType2 resource of the SL-PRS in the SL-PRS dedicated resource pool, it is possible to reuse the existing MAC-CE format for confirming the status of the CGType2 resource configured for sidelink communication, and also to confirm the status of the CGType2 resource of the SL-PRS in the SL-PRS dedicated resource pool.

[0150] The following embodiments will describe the time-sharing confirmation of the status of SL-PRS CG type2 resources or sidelink CG Type2 resources, which can not only confirm the status of SL-PRS CGType2 resources in the SL-PRS dedicated resource pool, but also confirm the status of CGType2 resources configured for sidelink communication.

[0151] As shown in Figure 7, a flow chart of another resource status confirmation method provided in an embodiment of the present application is provided. Exemplarily, the method may include the following steps:

[0152] S701. An access network device sends first downlink control information to a terminal. Correspondingly, the terminal receives the first downlink control information.

[0153] In this embodiment, the terminal is configured with at least one second configured authorized resource, and the at least one second configured authorized resource is used to carry the first channel or the first signal.

[0154] The at least one second configuration authorization resource is a CG type 2 resource. When the access network device schedules a configuration authorization resource among the at least one second configuration authorization resource to transmit a first channel or a first signal, the access network device may send first downlink control information to the terminal, where the first downlink control information is used to activate the first configuration authorization resource. The first configuration authorization resource is any one or more resources among the at least one second configuration authorization resource. In addition, when the first configuration authorization resource is to be released, the access network device may send first downlink control information to the terminal, where the first downlink control information is used to deactivate the first configuration authorization resource.

[0155] Furthermore, the first downlink control information includes an index of a first configured authorized resource.

[0156] S702. In response to the first downlink control information, the terminal sends first information to the access network device. Correspondingly, the access network device receives the first information.

[0157] After receiving the first downlink control information, the terminal needs to provide feedback to the access network device regarding the status of the at least one second configured authorization resource. Exemplarily, the status of each of the at least one second configured authorization resource is provided to the access network device. This status includes an activated state and an inactivated state. Therefore, the terminal sends first information to the access network device. The first information indicates the status of the at least one configured second configured authorization resource.

[0158] Exemplarily, the first information is a first MAC-CE, which is used to indicate the status of at least one configured second configuration authorization resource. The format of the first MAC-CE can be referred to FIG4 .

[0159] S703. The access network device sends second downlink control information to the terminal. Correspondingly, the terminal receives the second downlink control information.

[0160] In this embodiment, the terminal is configured with at least one fourth configured authorized resource, and the at least one fourth configured authorized resource is used to carry the second channel or the second signal.

[0161] The at least one fourth configured authorized resource is a CG type 2 resource. When the access network device schedules a configured authorized resource among the at least one fourth configured authorized resource to transmit a second channel or a second signal, the access network device may send second downlink control information to the terminal, where the second downlink control information is used to activate the third configured authorized resource. The third configured authorized resource is any one or more resources among the at least one fourth configured authorized resource. In addition, when the third configured authorized resource is to be released, the access network device may send second downlink control information to the terminal, where the second downlink control information is used to deactivate the third configured authorized resource.

[0162] Furthermore, the second downlink control information includes an index of a third configured authorization resource. The index of the first configured authorization resource included in the first downlink control information and the index of the third configured authorization resource included in the second downlink control information may be the same as or different from each other. The indexes of the at least one second configured authorization resource and the at least one fourth configured authorization resource are independently configured.

[0163] S704. In response to the second downlink control information, the terminal sends second information to the access network device. Correspondingly, the access network device receives the second information.

[0164] After receiving the second downlink control information, the terminal needs to provide feedback to the access network device regarding the status of the at least one fourth configured authorized resource. Exemplarily, the status of each of the at least one fourth configured authorized resource is provided to the access network device. This status includes an activated state and an inactivated state. Therefore, the terminal sends second information to the access network device. The second information indicates the status of the at least one configured fourth configured authorized resource.

[0165] Exemplarily, the second information is a second MAC-CE, which is used to indicate the status of at least one configured fourth configuration authorization resource. The format of the second MAC-CE can be referred to FIG4 .

[0166] The first channel is different from the second channel, and the first signal is different from the second signal, that is, the channel or signal carried by at least one second configuration authorized resource is different from the channel or signal carried by at least one fourth configuration authorized resource.

[0167] In this embodiment, the terminal does not receive the second downlink control information before sending the first information.

[0168] For example, for a terminal, if the terminal does not receive the second downlink control information before sending the first information, it can also be understood that the terminal does not expect the access network device to send the second downlink control information, or the terminal receives the second downlink control information after sending the first information. For an access network device, if the access network device does not send the second downlink control information before receiving the first information, it can also be understood that the access network device does not require the terminal to receive the second downlink control information before receiving the first information, or the access network device sends the second downlink control information after receiving the first information.

[0169] For example, in the SL-PRS dedicated resource pool, in resource allocation mode, if the terminal is configured with the SL-PRS CGType2 resource index of sl-PRS-ConfigIndexCG, the configured SL-PRS CGType2 index and the sidelink communication CGType2 resource index are independent, that is, the index values ​​can be the same or different.

[0170] As shown in Figure 8, which is a schematic diagram of resource status confirmation of the embodiment shown in Figure 7, after the access network device sends DCI 3_0 to activate or deactivate the sidelinkCGtype2 resource, before the access network device correctly receives the MAC-CE1 sent by the sending terminal to confirm the status of the sidelinkCGtype2, that is, within the time period T1 to T3, the access network device does not send DCI 3_2 to activate or deactivate the SL-PRS CGtype2 resource configured on the SL-PRS dedicated resource pool. Therefore, after the access network device receives the MAC-CE, the access network device and the terminal can have the same understanding: the MAC-CE corresponds to the confirmation of the status of the sidelink communication CGtype2 resource.

[0171] Alternatively, after the access network device sends DCI 3_2 to activate or deactivate the SL-PRS CGtype2 resources, before the access network device correctly receives the MAC-CE2 for resource confirmation for SL-PRS CGtype2 sent by the sending terminal, that is, within the time period T1 to T3, the access network device does not send DCI 3_0 to activate or deactivate the sidelink communication CGtype2 resources, so that after the access network device receives the MAC-CE, the access network device and the terminal can have the same understanding: the MAC-CE corresponds to the confirmation of the status of the SL-PRS CGtype2 resources.

[0172] Exemplarily, the first downlink control information and / or the second downlink control information may be sent by the O-DU or the O-RU; and the first information and / or the second information may be received by the O-CU-CP.

[0173] According to a resource status confirmation method provided by an embodiment of the present application, before sending first information for confirming the status of at least one second configuration authorization resource, the terminal does not receive second control information sent by the access network device for activating or deactivating a third configuration authorization resource, and the access network device does not require the terminal to receive second downlink control information before receiving the first information, so that both the terminal and the access network device confirm that the first information is used to confirm the status of at least one second configuration authorization resource, thereby achieving accurate feedback on the status of the configuration authorization resource.
