Description

Technical Field

[0001] 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

[0002] The sending / receiving of sidelink-positioning reference signal (SL-PRS) between terminals can be performed 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 one 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 needs to be activated or deactivated by the physical downlink control channel (PDCCH) to provide SL-PRS resource authorization. When PDCCH activates CGtype2 resources, the sending terminal stores the SL-PRS resource authorization; when PDCCH deactivates CGtype2 resources, the sending terminal clears the stored SL-PRS resource authorization.

[0003] However, when PDCCH activates the CGtype2 resources, but the terminal does not receive the PDCCH, or receives the PDCCH but does not provide feedback, the network device believes that the CGtype2 resources have been activated, but the terminal believes that they have not been activated. The network device will reserve the CGtype2 resources, but the terminal will not actually send on the CGtype2 resources, resulting in a waste of resources.

[0004] 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).

[0005] 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. Summary of the invention

[0006] The present application provides a resource status confirmation method, device, system and storage medium to realize confirmation of the status of CGType2 resources of SL-PRS in an SL-PRS dedicated resource pool without conflicting with the information used to confirm the status of CGType2 resources for side link communication.

[0066] The solution of the present application is further described below in conjunction with the accompanying drawings.

[0067] Figure 1 A possible, non-limiting system schematic is shown. Figure 1 As shown, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. The communication system 1000 may also include the Internet 300. The RAN 100 includes at least one RAN node (such as Figure 1 110a and 110b, collectively referred to as 110) and at least one terminal (such as Figure 1 RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be different physical devices, or may be the same physical device that integrates the core network logical function and the radio access network logical function.

[0068] RAN100 may be a cellular system related to the third generation partnership project (3GPP), for example, a 4G, 5G mobile communication system, or a future evolution system (for example, a 6G mobile communication system). RAN100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a wireless fidelity (wireless fidelity, WiFi) system. RAN100 may also be a communication system that integrates two or more of the above systems.

[0069] The RAN node 110, which may also be sometimes referred to as an access network device, a RAN entity or an access node, constitutes a part of the communication system to help the terminal achieve wireless access. The multiple RAN nodes 110 in the communication system 1000 may be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, for example, Figure 1 The network element 120i may be a helicopter or a drone, which may be configured as a mobile base station. For the terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication devices, for example Figure 1 The network elements 110a and 110b may be understood as communication devices having base station functions, and the network elements 120a-120j may be understood as communication devices having terminal functions.

[0070] 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 (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the example above), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an onboard device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU).

[0071] 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 can also 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).

[0072] 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 (opern-CU, O-CU), DU may also be called an open-distributed unit (opern-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 the convenience of description, CU, CU-CP, CU-UP, DU and RU are used as examples for description in this application. Any of the CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0073] The terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, for example, 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 wear, smart transportation, smart city, etc. The terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.

[0074] 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.

[0075] For the network elements in the ORAN system and the corresponding relationship between the protocol layer functions that can be implemented, please refer to the following Table 1:

[0078] Base stations and terminals can be fixed or movable. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0079] The roles of the base station and the terminal can be relative, for example, Figure 1 The helicopter or drone 120i in the figure can be configured as a mobile base station. For the terminal 120j that accesses the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between base stations. In this case, relative to 110a, 120i is also a base station. Therefore, base stations and terminals can be collectively referred to as communication devices. Figure 1 110a and 110b in the figure may be referred to as communication devices having base station functions. Figure 1 120a-120j in the figure can be called communication devices with terminal functions.

[0080] In the embodiments of the present application, the base station is also referred to as an access network device, and the device for implementing the function of the access network device may be an access network device; or it may be a device capable of supporting the access network device to implement the function, such as a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module. The device may be installed in the access network device or used in combination with the access network device. In the embodiments of the present application, only the device for implementing the function of the access network device is an access network device as an example for explanation, and the scheme of the embodiments of the present application is not limited.

[0081] It can be understood that the present application can be applied between access network equipment and terminals.

[0082] It should be understood that Figure 1 The number and type of each device in the communication system shown are for illustration only, and the present application is not limited thereto. 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.

[0083] 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 used to implement 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 the interface of 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 equipment, core network equipment, or network elements used to implement artificial intelligence functions can be implemented by cloud devices, such as cloud devices in over the top (OTT) systems.

[0084] 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 channels 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. For example Figure 2 As shown, it is a schematic diagram of a sidelink channel and signal mapping of an example embodiment of the present application, taking 14 orthogonal frequency division multiplexing (OFDM) symbols in a time slot as an example, and illustrating the resource mapping diagram of PSCCH, PSSCH, DMRS, and SL-PRS transmission. Among them, PSCCH carries the first-level sidelink control information (sidelink control information, SCI) SCI 1-A, which is used to schedule PSSCH and the second-level SCI carried on PSSCH. Both the first-level SCI and the second-level SCI belong to the sidelink control information, which contains complete control information for scheduling PSSCH and SL-PRS. DMRS is a demodulation reference signal for demodulating data. SL-PRS is a positioning reference signal sent by terminal A.

[0085] In addition, the sending / receiving of SL-PRS between terminals can also be sent only on a dedicated resource pool. Figure 3 As shown, 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 the 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 side link control information, which contains complete control information for scheduling SL-PRS.

[0086] The present application mainly relates to transmitting SL-PRS on a dedicated resource pool.

[0087] When the SL-PRS is sent on the dedicated resource pool, there are two modes of resource allocation.

[0088] Mode 1: The resources for sending SL-PRS may be resources dynamically scheduled (dynamic grant, DG) by the access network device, or resources configured with grant (configured grant, CG).

[0089] Mode 2: The terminal autonomously determines the sending resources. Specifically, the upper layer (MAC / RRC layer) inside the terminal requests the terminal to determine a resource set, and the upper layer selects resources from the resource set to send SL-PRS.

[0090] For resource allocation mode 1, the configuration of authorized resource CG includes two types:

[0091] Configuration authorization type 1 (CGtype1): The SL-PRS 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 SL-PRS resource authorization. When the SL-PRS needs to be sent, it directly uses the configured authorized resources to send the SL-PRS.

[0092] Configuration Grant Type 2 (CGtype2): SL-PRS resource grant is activated or deactivated by the physical downlink control channel (PDCCH). When PDCCH activates CGtype2 resources, the transmitting terminal stores the SL-PRS resource grant; when PDCCH deactivates CGtype2 resources, the transmitting terminal clears the stored SL-PRS resource grant.

[0093] 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 (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 (identifier, ID), number of SL-PRS symbols, SL-PRS density in the frequency domain, and SL-PRS offset in the frequency domain.

[0094] For CGtype2, the resource configuration provided by the access network device includes at least: CG index, CG period, 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. Downlink control information DCI3_2 for scheduling SL-PRS resources is used to activate or deactivate CGtype2.

[0095] 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 consent (acknowledgement, ACK) information of correctly receiving 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 resources of CGtype2 in time, resulting in a waste of resources.

[0096] There is currently no technology on how to provide feedback on the status of CG type2.

[0097] For sidelink communications, including the transmission of PSCCH and PSSCH channels, there are also two modes of resource allocation.

[0098] Mode 1: The resources for sidelink communication may be resources dynamically scheduled by the access network device, or configured authorized resources.

[0099] Mode 2: The terminal autonomously determines the sending resources. Specifically, the upper layer inside the terminal requests the terminal to determine a resource set, and the upper layer selects resources from the resource set for sidelink communication.

[0100] For resource allocation mode 1, configuring authorized resources includes two types:

[0101] CGtype1: The sidelink resource authorization is provided by the access network equipment 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 needed, it directly uses the configured authorized resources for sidelink communication.

[0102] 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.

[0103] 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) of the CGtype2 resource deactivation confirmation, the MAC entity clears the stored CGtype2 resources. 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, and the terminal sends the confirmation MAC-CE of the CGtype2 resource activation.

[0104] like Figure 4 As shown in FIG. 1 , a schematic diagram of the format of a MAC-CE is shown. The MAC header in the MAC-CE includes a special extended logic channel identifier (eLCID) number, which is used to associate the confirmation of the CG type2 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 configured CGType2 resource with index sl-ConfigIndexCG does not have i, then C i is ignored. 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.

[0105] However, the above MAC-CE can only be used to confirm the activation or deactivation status of the CGType2 resources configured for the 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 the sidelink communication and the activation or deactivation status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool.

[0106] 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, and to confirm the activation or deactivation status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool.

[0107] To solve the above problems, multiple embodiments are described below:

[0108] like Figure 5 FIG. 1 is a flow chart of a method for confirming resource status provided by an embodiment of the present application. Exemplarily, the method may include the following steps:

[0109] S501. The access network device sends downlink control information (DCI) to the terminal. Correspondingly, the terminal receives the downlink control information.

[0110] In this embodiment, the terminal is configured with at least one second configuration authorization resource. The at least one second configuration authorization resource is used to send the SL-PRS. The at least one second configuration authorization resource belongs to a resource of a dedicated resource pool for transmitting the SL-PRS.

[0111] The at least one second configuration authorization resource is a CG type2 resource. When the access network device schedules a configuration authorization resource in the at least one second configuration authorization resource to transmit SL-PRS, the access network device can send downlink control information to the terminal, and the downlink control information is used to activate the first configuration authorization resource. The first configuration authorization resource is any one or more resources in the at least one second configuration authorization resource. In addition, when the first configuration authorization resource is to be released, the access network device can send downlink control information to the terminal, and the downlink control information is used to deactivate the first configuration authorization resource.

[0112] Furthermore, the downlink control information includes an index of the first configuration authorization resource. Each configuration authorization resource has a unique index.

[0113] Exemplarily, the above downlink control information may be sent by the O-DU or the O-RU.

[0114] Exemplarily, the downlink control information is DCI3_2. The access network device may configure eight configuration authorization resources C1 to C8 for the terminal.

[0115] S502. The terminal sends first information to the access network device in response to the downlink control information. Correspondingly, the access network device receives the first information.

[0116] Exemplarily, the first information may be received by the O-CU-CP.

[0117] After receiving the downlink control information, the terminal needs to feed back the state of the at least one second configuration authorization resource to the access network device. Exemplarily, the state of each second configuration authorization resource in the at least one second configuration authorization resource is fed back to the access network device. The state includes an activated state and an inactivated state. Therefore, the terminal sends the first information to the access network device. The first information is used to indicate the state of the at least one second configuration authorization resource being configured.

[0118] In addition, the method may further include: the terminal receives DCI3_0 sent by the access network device, the DCI3_0 is used to activate or deactivate a fourth configuration authorization resource, the fourth configuration authorization resource is any one of the at least one third configuration authorization resource. The terminal sends second information to the access network device.

[0119] The first information includes a first identifier. The first identifier is different from a second identifier in the second information, and the second information is used to indicate the state of at least one third configured authorization resource configured, and the at least one third configured authorization resource is used to send PSCCH and / or PSSCH, that is, the at least one third configured authorization resource is used for sidelink communication.

[0120] 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 resources for sending SL-PRS, or for confirming the status of the CGType2 resources for the side link communication configuration.

[0121] Exemplarily, the first information is a first MAC-CE, and the first MAC-CE is used to indicate the state of at least one second configured authorization resource. The format of the first MAC-CE can refer to Figure 4 , which is the same format as 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:

[0122] 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 i. Otherwise, if the configured SL-PRS CGType2 resource with index sl-PRS-ConfigIndexCG does not have i, then C i is ignored. i When set to 1, it indicates that the SL-PRSCGType2 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 index sl-PRS-ConfigIndexCG i is confirmed to be deactivated.

[0123] The first identifier is a first eLCID number, and the first eLCID number is located at the header of the first MAC-CE. For example, the first eLCID code point is 253, and the corresponding index value is 317.

[0124] 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 confirmation of deactivation of the SL-PRS CGType2 resource. After the terminal sends MAC-CE for confirmation of deactivation of the SL-PRS CGType2 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 a MAC-CE for confirmation of activation of the SL-PRS CGType2 resource.

[0125] The second information is a second MAC-CE, and the second MAC-CE is used to indicate the state of at least one third configuration authorization resource configured. The second information is used to respond to DCI3_0. The state includes an activated state and an inactivated state. Among them, the second identifier is a second eLCID number, and the second eLCID number is located at the header of the second MAC-CE.

[0126] On the dedicated SL-PRS resource pool, the status of the SL-PRS CGType2 resource is confirmed without affecting the status of the sidelink communication CG type2 resource. It is also possible to simultaneously confirm the status of the SL-PRS CGType2 resource and the status of the sidelink communication CG type2 resource. The two confirmations are independent, and the index of the SL-PRSCGType2 resource and the index of the sidelink communication CG type2 resource can be the same or different. The index configuration of the two resources is also independent.

[0127] According to a resource status confirmation method provided by an embodiment of the present application, when a terminal receives downlink control information sent by an access network device for activating or deactivating a first configured authorization resource, the terminal sends first information to the access network device to indicate the status of at least one second configured authorization resource being 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 resources configured for the side link communication, thereby realizing confirmation of the status of the CGType2 resources used to send SL-PRS without conflicting with the second information.

[0128] In another embodiment, a communication method is also provided, which includes the following steps: the access network device sends first downlink control information to the 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 SL-PRS. The at least one second configuration authorization resource belongs to a resource of a dedicated resource pool for transmitting 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 of 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 at least one third configuration authorization resource. Wherein, the first information includes a first identifier. The first identifier is different from the second identifier in the second information, and the second information is used to indicate the state of at least one third configured authorization resource configured, and the at least one third configured authorization resource is used to send PSCCH and / or PSSCH, that is, the at least one third configured authorization resource is used for side link 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 state of at least one second configured authorization resource configured. 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 state of at least one third configured authorization resource configured. 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.

[0129] The above embodiment describes how to confirm the status of the CGType2 resources configured for the sidelink communication by means of 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.

[0130] 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 communications.

[0131] like Figure 6FIG. 1 is a flow chart of another resource status confirmation method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:

[0132] S601. The access network device sends downlink control information to the terminal. Correspondingly, the terminal receives the downlink control information.

[0133] Exemplarily, the downlink control information may be sent by the O-DU or the O-RU.

[0134] In this embodiment, the terminal is configured with at least one second configuration authorization resource. The at least one second configuration authorization resource is used to send the SL-PRS. The at least one second configuration authorization resource belongs to a resource of a dedicated resource pool for transmitting the SL-PRS.

[0135] The terminal is also configured with at least one third configuration grant resource. The at least one third configuration grant resource is used to send PSCCH and / or PSSCH, that is, the at least one third configuration grant resource is used for sidelink communication.

[0136] The index of at least one second configuration authorization resource is different from the index of at least one third configuration authorization resource.

[0137] The at least one second configuration authorization resource and the at least one third configuration authorization resource are CG type2 resources. When the access network device schedules a configuration authorization resource in at least one second configuration authorization resource to transmit SL-PRS, or schedules a configuration authorization resource in at least one third configuration authorization resource for side link communication, the access network device can send downlink control information to the terminal, and the downlink control information is used to activate the first configuration authorization resource. The first configuration authorization resource is any one or more resources in the at least one second configuration authorization resource or at least one third configuration authorization resource. In addition, when the first configuration authorization resource is to be released, the access network device can send downlink control information to the terminal, and the downlink control information is used to deactivate the first configuration authorization resource.

[0138] Furthermore, the downlink control information includes an index of the first configuration authorization resource. Each configuration authorization resource has a unique index.

[0139] S602. The terminal sends first information to the access network device in response to the downlink control information. Correspondingly, the access network device receives the first information.

[0140] Exemplarily, the first information may be received by the O-DU or the O-RU.

[0141] 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 resources configured for the sidelink 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.

[0142] 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 state of any one of the resources fed back corresponds to according to the index of the resource, thereby knowing the state of the CGType2 resource used to confirm the transmission of SL-PRS, and the state of the CGType2 resource used for side link communication configuration.

[0143] Exemplarily, the first information is MAC-CE, and the format of the MAC-CE can be referred to Figure 4 . Wherein, the MAC-CE includes a first field and / or a second field, the first field is used to indicate the state of at least one second configuration authorization resource, and the second field is used to indicate the state of at least one third configuration authorization resource. Wherein, the state includes an activated state and an inactivated state. The sum of the number of the at least one second configuration authorization resource and the 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 state of the CGType2 resources for transmitting SL-PRS, and C5 to C8 correspond to the state of the CGType2 resources for the sidelink communication configuration.

[0144] 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 of the configured SL-PRS and the number of CGType2 resource configuration sets of the 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 of the 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 of the sidelink communication.

[0145] If the terminal receives DCI 3_2 carried by PDCCH, indicating deactivation of a SL-PRS CGType2 resource; or receives DCI 3_0 carried by PDCCH, indicating deactivation of a sidelinkCGType2 resource, the MAC entity of the sending terminal triggers the deactivation confirmation of the SL-PRS CGType2 resource in response to DCI 3_2 or the sidelinkCGType2 resource in response to DCI 3_0. After the terminal sends the MAC-CE of the deactivation confirmation of the SL-PRS CG Type2 resource and / or the sidelinkCGType2 resource, the MAC entity clears the stored SL-PRS CGType2 resource and / or the sidelinkCGType2 resource. Alternatively, if the terminal receives DCI 3_2 carried by PDCCH indicating activation of a SL-PRS CGType2 resource, or receives DCI 3_0 carried by PDCCH indicating activation of a sidelinkCGType2 resource, the MAC entity of the sending terminal triggers confirmation of the SL-PRS CGType2 resource and / or the sidelinkCGType2 resource, and stores the SL-PRS CGType2 resource or the sidelinkCGType2 resource, and the terminal sends a confirmation MAC-CE for activation of the SL-PRS CGType2 resource and / or the sidelinkCGType2 resource. Specifically, when DCI 3_0 is received, before receiving DCI3_2, the terminal has not sent a confirmation message in response to 3_0, and after receiving DCI3_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 sidelinkCGType2 resource. Alternatively, when DCI3_2 is received, before receiving DCI3_0, the terminal has not sent a confirmation message in response to 3_2. After receiving DCI3_0, 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 SL-PRSCGType2 resources and sidelinkCGType2 resources.

[0146] Therefore, the same confirmation MAC-CE can be used to confirm the status of the SL-PRS CG type2 resource, or to simultaneously confirm the status of the SL-PRS CG type2 resource and the sidelink CG Type2 resource.

[0147] According to a resource status confirmation method provided in an embodiment of the present application, by setting the index of the CGType2 resources configured for side link communication to be different from the index of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool, it is possible to confirm both the status of the CGType2 resources configured for side link communication and the status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool through one information.

[0148] The above embodiment describes that by setting the index of the CGType2 resources configured for sidelink communication to be different from the index of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool, it is possible to confirm the status of the CGType2 resources of the SL-PRS in the SL-PRS dedicated resource pool by reusing the existing MAC-CE format for confirming the status of the CGType2 resources configured for sidelink communication.

[0149] 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 CGType2 resources of SL-PRS in the SL-PRS dedicated resource pool, but also confirm the status of CGType2 resources configured for sidelink communication.

[0150] like Figure 7 FIG. 1 is a flow chart of another resource status confirmation method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:

[0151] S701. The access network device sends first downlink control information to the terminal. Correspondingly, the terminal receives the first downlink control information.

[0152] 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 carry the first channel or the first signal.

[0153] The at least one second configuration authorization resource is a CG type2 resource. When the access network device schedules a configuration authorization resource in at least one second configuration authorization resource to transmit a first channel or a first signal, the access network device can send a first downlink control message to the terminal, and the first downlink control message is used to activate the first configuration authorization resource. The first configuration authorization resource is any one or more resources in the at least one second configuration authorization resource. In addition, when the first configuration authorization resource is to be released, the access network device can send a first downlink control message to the terminal, and the first downlink control message is used to deactivate the first configuration authorization resource.

[0154] Furthermore, the first downlink control information includes an index of a first configured authorization resource.

[0155] S702. The terminal sends first information to the access network device in response to the first downlink control information. Correspondingly, the access network device receives the first information.

[0156] After receiving the first downlink control information, the terminal needs to feed back the state of the at least one second configuration authorization resource to the access network device. Exemplarily, the state of each second configuration authorization resource in the at least one second configuration authorization resource is fed back to the access network device. The state includes an activated state and an inactivated state. Therefore, the terminal sends the first information to the access network device. The first information is used to indicate the state of the at least one second configuration authorization resource being configured.

[0157] Exemplarily, the first information is a first MAC-CE, and the first MAC-CE is used to indicate the state of at least one second configured authorization resource. The format of the first MAC-CE can refer to Figure 4 .

[0158] S703. The access network device sends second downlink control information to the terminal. Correspondingly, the terminal receives the second downlink control information.

[0159] In this embodiment, the terminal is configured with at least one fourth configuration authorized resource. The at least one fourth configuration authorized resource is used to carry the second channel or the second signal.

[0160] The at least one fourth configuration authorization resource is a CG type 2 resource. When the access network device schedules a configuration authorization resource in at least one fourth configuration authorization resource to transmit a second channel or a second signal, the access network device can send a second downlink control information to the terminal, and the second downlink control information is used to activate the third configuration authorization resource. The third configuration authorization resource is any one or more resources in the at least one fourth configuration authorization resource. In addition, when the third configuration authorization resource is to be released, the access network device can send a second downlink control information to the terminal, and the second downlink control information is used to deactivate the third configuration authorization resource.

[0161] Further, the second downlink control information includes an index of a third configuration authorization resource. The index of the first configuration authorization resource included in the first downlink control information and the index of the third configuration authorization resource included in the second downlink control information may be the same or different. The indexes of the at least one second configuration authorization resource and the at least one fourth configuration authorization resource are independently configured.

[0162] S704. The terminal sends second information to the access network device in response to the second downlink control information. Correspondingly, the access network device receives the second information.

[0163] After receiving the second downlink control information, the terminal needs to feedback the state of the at least one fourth configuration authorization resource to the access network device. Exemplarily, the state of each fourth configuration authorization resource in the at least one fourth configuration authorization resource is fed back to the access network device. The state includes an activated state and an inactivated state. Therefore, the terminal sends the second information to the access network device. The second information is used to indicate the state of the at least one fourth configuration authorization resource configured.

[0164] Exemplarily, the second information is a second MAC-CE, and the second MAC-CE is used to indicate the state of at least one fourth configured authorization resource that is configured. The format of the second MAC-CE can refer to Figure 4 .

[0165] 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.

[0166] In this embodiment, the terminal does not receive the second downlink control information before sending the first information.

[0167] Exemplarily, for a terminal, the terminal does not receive the second downlink control information before sending the first information, which can also be understood as 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, the access network device does not send the second downlink control information before receiving the first information, which can also be understood as 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.

[0168] For example, in the SL-PRS dedicated resource pool, in resource allocation mode, if the terminal is configured with SL-PRS CGType2 resource index sl-PRS-ConfigIndexCG, the configured SL-PRS CGType2 index is independent of the CGType2 resource index for sidelink communication, that is, the index values ​​can be the same or different.

[0169] like Figure 8 As shown, Figure 7A schematic diagram of resource status confirmation of the illustrated embodiment shows that after the access network device sends DCI 3_0 to activate or deactivate the sidelinkCGtype2 resources, before the access network device correctly receives the MAC-CE1 for status confirmation of the sidelinkCGtype2 sent by the sending terminal, that is, in the time period T1 to T3, the access network device does not send DCI 3_2 to activate or deactivate the SL-PRS CGtype2 resources configured on the SL-PRS dedicated resource pool, 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 sidelink communication CGtype2 resources.

[0170] 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 the SL-PRS CGtype2 sent by the sending terminal, that is, in 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.

[0171] 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.

[0172] 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.

[0173] It is understandable that the present application uses access network devices and terminals as examples of the execution subjects of the interactive illustrations, but the present application does not limit the execution subjects of the interactive illustrations.
