Description

Technical Field

[0001] Embodiments of the present application relate to Internet of Things technology, and more particularly, to a method, apparatus, device, and storage medium for indicating the status of a device in a sidelink. Background Art

[0002] Device-to-device (D2D) communication is a sidelink transmission technology (SL). Unlike traditional cellular systems where communication data is received or sent through base stations, the Internet of Vehicles system uses direct device-to-device communication, resulting in higher spectrum efficiency and lower transmission latency.

[0003] The 3rd Generation Partnership Project (3GPP) defines two transmission modes: Mode A and Mode B. In Mode A, the device's transmission resources are allocated by the base station, and the device transmits data on the sidelink based on the resources allocated by the base station. The base station can allocate resources for a single transmission or for semi-static transmission. In Mode B, the onboard device selects a resource from the resource pool for data transmission. Generally speaking, users within network coverage will obtain resources and configurations for sidelink transmission from their base station. In the sidelink power saving mechanism, the power saving mechanism configuration parameters will also be configured by the network to the device within its coverage range, and further sent by the device to the other device with which it conducts sidelink communication. The two parties communicate based on this configuration. In the sidelink power saving mechanism, when the receiving (receive, abbreviated as: Rx) device receives a message that requires a reply from the transmitting (transmit, abbreviated as: Tx) device, it needs to apply for resources from its network to transmit the reply message to the Tx device. At this time, since the network knows the discontinuous reception (DRX) configuration of the Tx device, it will not issue the configuration authorization in time because it believes that the Tx device is in a sleep state, resulting in transmission failure.

[0056] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] The terms "first", "second", etc. in the specification, claims, and above-mentioned drawings of the embodiments of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0058] Taking the Internet of Vehicles as an example, the Internet of Vehicles system adopts direct device-to-device communication, so it has higher spectrum efficiency and lower transmission delay. Figure 1 This is a schematic diagram of a vehicle-mounted device side link transmission, such as Figure 1 As shown, 3GPP defines two transmission modes: Mode A and Mode B.

[0059] Mode A: The transmission resources of the on-board equipment are allocated by the base station, and the on-board equipment sends data on the sidelink according to the resources allocated by the base station. The base station can allocate resources for single transmission to the on-board equipment, or allocate resources for semi-static transmission to the on-board equipment.

[0060] Mode B: The on-board device selects a resource from the resource pool for data transmission.

[0061] In 3GPP, D2D is divided into different phases for research.

[0062] -Proximity based Service (ProSe): Device-to-device communication in Rel-12 / 13 is studied for ProSe scenarios, mainly targeting public safety services.

[0063] In ProSe, by configuring the position of the resource pool in the time domain, for example, the resource pool is discontinuous in the time domain, the device can transmit / receive data discontinuously on the side link, thereby achieving power saving.

[0064] Vehicle-to-X (V2X): In Rel-14 / 15, the V2X system focused on vehicle-to-vehicle communication scenarios, primarily targeting relatively high-speed vehicle-to-vehicle and vehicle-to-pedestrian communication services.

[0065] In V2X, since the on-board system has continuous power supply, power efficiency is not the main issue, but the delay of data transmission is the main issue. Therefore, the system design requires the terminal equipment to perform continuous transmission and reception.

[0066] - Wearable devices (FeD2D): In Rel-14, this scenario studies the scenario of wearable devices accessing the network through mobile phones, mainly targeting scenarios with low mobile speed and low power access.

[0067] Compared with Long Term Evolution (LTE), in the research of new radio (NR) networks, NR V2X, based on LTE V2X, is not limited to broadcast scenarios, but further expanded to unicast and multicast scenarios, and the application of V2X is studied in these scenarios.

[0068] Similar to LTE V2X, NR V2X will also define the two resource authorization modes mentioned above, mode-A and mode-B. Furthermore, users may be in a mixed mode, that is, they can use mode-A to obtain resources and mode-B to obtain resources at the same time.

[0069] Unlike LTE V2X, in addition to the feedback-free, device-initiated HARQ retransmission, NR V2X introduces feedback-based Hybrid Automatic Repeat reQuest (HARQ) retransmission, which is not limited to unicast communications but also includes multicast communications.

[0070] Similar to LTE V2X, in NR V2X, power efficiency is not a major issue because the on-board system has continuous power supply, but data transmission latency is the main issue. Therefore, the system design requires terminal devices to perform continuous transmission and reception.

[0071] Figure 2 FIG. 1 is a schematic diagram of resource configuration for sidelink transmission in the prior art. Figure 2As shown, during existing sidelink device communications, users within network coverage will obtain resources and configurations for sidelink transmission from their base station. In the sidelink power-saving mechanism, the network will also configure power-saving mechanism configuration parameters for devices within its coverage area. These devices will then transmit these parameters to the other device with which they are engaging in sidelink communication, and both parties will communicate based on these configurations.

[0072] The main differences between the sidelink power saving technology and the existing uplink and downlink power saving technologies are:

[0073]

[0074] According to the above table, in the sidelink power saving mechanism, when the Rx device receives a message from the Tx device that requires a reply, it needs to apply for resources from its own network to transmit the reply message to the Tx device. At this time, because the network knows the DRX configuration of the Tx device, it will not issue the configuration authorization in time because it believes that the Tx device is in a dormant state, resulting in transmission failure. The reason for this problem is that there are both relatively static configurations (on duration timer) and relatively dynamic situations (in active timer) in the DRX mechanism. Therefore, the device should report the relevant dynamic situation to its network to avoid the above problem. The following issues should be considered when the device reports to the network:

[0075] - When the report is triggered;

[0076] - What signal carries the report?

[0077] - What should be included in the report.

[0078] To address the above issues, this application provides a method for reporting the status of the other device to the network in a sidelink power saving mechanism, so that the network can fully understand the DRX status of the other device and enable the Rx device to obtain transmission resources in a timely manner when it needs to reply to the message from the Tx device. The methods for reporting to the network here mainly include the following three forms:

[0079] 1. Physical layer signaling;

[0080] 2. Media Access Control Control Element (MAC CE)

[0081] 3. Radio Resource Control (RRC) signaling.

[0082] The following is a detailed description of the method for indicating the device status in the side link provided by this application through a specific implementation method. The technical solution provided by this application can be applied in any side link transmission scenario, involving a first device at the transmitting end, a second device at the receiving end, and a network device serving the second device. In this solution, the first device and the second device can be vehicles, vehicle-mounted devices, mobile phones, tablet computers, wearable devices, and other terminal devices capable of device-to-device transmission, and this solution does not impose any restrictions on this.

[0083] Figure 3 A flow chart of a first embodiment of a method for indicating the status of a device in a side link provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the method for indicating the device status in the side link includes the following steps:

[0084] S101: Send a first message to a second device via a sidelink.

[0085] In this step, the first message sent by the first device to the second device is a message that requires a response. The first message can be any of the following information that requires a response:

[0086] Physical layer information;

[0087] MAC CE information, such as CSI report scheduling information, etc.

[0088] Radio Link Control (RLC) layer information, such as RLC status report scheduling information.

[0089] Packet Data Convergence Protocol (PDCP) layer information.

[0090] RRC signaling, such as device capability acquisition information, measurement report scheduling information, RRC reconfiguration information, etc.

[0091] S102: The DRX state is activated for the first time.

[0092] In this step, the first device enters the DRX activation state after a period of time after sending the first message to the second device, that is, enters the state of waiting to receive a response from the second device. Specifically, the first device can enter the DRX activation state at a first time. The first time is a time period. The first device enters the DRX activation state at the beginning of the first time and maintains the DRX activation state during the first time. The first time is determined based on the first message.

[0093] Specifically, if the first message is physical layer information, the first time is the time slot corresponding to the physical layer information. In sidelink transmission, when the first message is physical layer information, the first device sends the first message to the second device via the sidelink data channel (Physical Sidelink Share Channel, abbreviated as: PSSCH), and the second device needs to transmit response information to the first device via the sidelink feedback channel (Physical Sidelink Feedback Channel, abbreviated as: PSFCH). Therefore, the first time refers to the time slot where the PSFCH is located, that is, the time slot corresponding to the PSSCH that transmits the physical layer information.

[0094] If the first message is information other than physical layer information, the first time is a time period during which a timer configured for DRX is used. In a specific implementation of this situation, the first device starts a first timer some time after sending the first message. The first time is a time period during which the first timer is used. The duration of the first timer is determined according to the DRX configuration of the first device.

[0095] S103: Send first indication information to the network device.

[0096] In this step, the second device receives a first message sent by the first device via the sidelink, where the first message is a message requiring a response. At this point, due to the DRX configurations of the two devices, the network may believe that the first device is in DRX sleep mode, and therefore cannot obtain resources in a timely manner to respond to the first device.

[0097] In this solution, after receiving the first message requiring a response from the first device, the second device may send an indication message to the network device, that is, send the first indication message. The first indication message is used to indicate that the first device has sent a message requiring a response and / or that the first device is in a DRX activated state.

[0098] The network device receives the first indication information sent by the second device. Based on the first indication message, the network device can know that the first device has sent a message that requires a response to the second device and / or the first device is in a DRX activation state, that is, the first device is waiting for the response of the second device. Therefore, the network device can configure a responsive sidelink transmission resource to the second device so that the second device can send a responsive message to the first device based on the resource.

[0099] In a specific implementation of this solution, the first indication information may use a physical layer address to distinguish a first device configured for DRX that performs sidelink communication with a second device. That is, the first indication information includes the physical layer address, and the physical layer address indicates the first device in the DRX-activated state. Alternatively, the first device configured for DRX that performs sidelink communication with the second device may be distinguished by adding a DRX configuration identifier. That is, the first indication information may include the DRX configuration identifier to indicate the first device in the DRX-activated state to the network device. This solution does not limit the specific method used to indicate the network device.

[0100] Figure 4 The flowchart of the second embodiment of the method for indicating the status of the device in the side link provided by the embodiment of the present application is as follows: Figure 4 As shown, based on the above embodiment, on the second device side, the method for indicating the device status in the sidelink further includes the following steps:

[0101] S104: Acquire sidelink transmission resources.

[0102] S105: Send a second message in response to the first message to the first device through the sidelink transmission resource.

[0103] In this solution, after sending the first indication information to the network device, the second device needs to obtain side link transmission resources to respond to the first device.

[0104] In one implementation, the network device may configure a responsive sidelink transmission resource for the second device, so that the second device can send a responsive message to the first device based on the resource pair.

[0105] After configuring the sidelink transmission resources for the second device to respond to the first device, the network device sends the sidelink transmission resources to the second device.

[0106] After acquiring the sidelink transmission resource, the second device sends a second response message to the first device through the sidelink transmission resource, that is, responds to the first message sent by it.

[0107] Optionally, in addition to obtaining sidelink transmission resources according to the configuration of the network device, the second device can also select appropriate resources from a pre-configured sidelink resource pool to respond to the first device, and this solution does not impose any restrictions on this.

[0108] For the first device, if the first message sent is physical layer information, the second message responded by the second device is received in the time slot corresponding to the physical layer.

[0109] If the first message sent is information other than physical layer information, a second message in response to the second device is received during the timing of the first timer, and the timing of the first timer is stopped if the second message is successfully received.

[0110] The aforementioned embodiment provides a method for indicating the status of a device in a sidelink. After the first device sends a first message requiring a response to the second device, the first device enters a DRX activation state immediately. After receiving the first message requiring a response, the second device sends a first indication message to the network device to which the second device is connected, indicating that the first device requires a response or is in a DRX activation state, so that the network device can know that the first device has sent a message requiring a response or is in a DRX activation state based on the first indication message, and can promptly configure transmission resources for the sidelink for the second device. The second device can respond to the first message sent by the first device based on the resources. A method for reporting the status of the sending device to the network in a sidelink power saving mechanism is provided, so that the network side can promptly configure resources, and the second device can promptly reply to messages requiring a response in the sidelink, thereby avoiding transmission failures.

[0111] Based on the above embodiments, the method for indicating the status of a device in a sidelink provided by the present application is described in detail below through several specific implementations.

[0112] Figure 5 The flowchart of the third embodiment of the method for indicating the status of the device in the side link provided by the embodiment of the present application is as follows: Figure 5 As shown, the method for indicating the device status in the side link specifically includes the following steps:

[0113] S201: Send a first message requiring a response to a second device.

[0114] After the first device sends a first message requiring a response to the second device, an RTT timer may be started.

[0115] S202: The DRX state is activated for the first time.

[0116] S203: The second device sends UCI / MAC CE / RRC signaling to the network device.

[0117] In this solution, there is no order between S202 and S203.

[0118] S204: Acquire sidelink transmission resources.

[0119] S205: Send a second message in response to the first message to the first device.

[0120] Based on the above steps, in this solution, the second device as the receiving end can send UCI, MAC CE, or RRC signaling to the network device to indicate the status of the first device or send a message that requires a response. Specific implementation methods include the following:

[0121] Implementation method 1: reporting via physical layer signaling

[0122] The first implementation uses a physical layer address to distinguish a first device configured with DRX that is performing sidelink communication with a second device. Specifically, the physical layer address is included in the report message to indicate to the network that the first device is in the DRX active state. The specific steps are as follows:

[0123] 1. The first device sends a first message that requires a reply to the second device. The first message may be: physical layer information; MAC CE information, such as CSI report scheduling information; RLC layer information, such as RLC status report scheduling information; PDCP layer information; RRC signaling, such as UE capability acquisition information, measurement report scheduling information, RRC reconfiguration information, etc.

[0124] After sending the first message to the second device, the first device starts the RTT timer.

[0125] 2. The first device enters the DRX active state and prepares to receive a reply message from the second device, that is, a second message in response.

[0126] The active state is indicated by the INACTIVE timer, and the INACTIVE timer starts after the RTT timer expires.

[0127] 3. The second device receives the first message sent by the first device.

[0128] 4. The second device reports UCI information to the network, which indicates that the first device is waiting for a response and is in DRX active state;

[0129] The UCI information may include address information of the first device. For example, the address information may be transmitted using one or more bits. For example, in the BSR information, the address information is 5 bits. The priority of the UCI information is the same as the priority of the first message from the first device.

[0130] On the network device side, the network device receives first indication information, i.e., UCI information, sent by the second device, and confirms based on the UCI information that the first device has sent a message requiring a response to the second device and / or that the first device is in a discontinuous reception DRX activation state.

[0131] 5. The second device obtains the sidelink transmission resource through mode 1 / mode 2. That is, the transmission resource can be selected from the sidelink transmission resource pool or configured by the network device.

[0132] In one implementation, the network device may configure a sidelink transmission resource for the second device to respond to the first device, and send the sidelink transmission resource to the second device.

[0133] 6. The second device replies to the first message sent by the first device, that is, it can send a second message to the first device via the sidelink transmission resource.

[0134] 7. If the first device receives a response message from the second device, it stops the INACTIVE timer.

[0135] If the INACTIVE timer times out and no response information is received from the second device, it is considered that the transmission has failed.

[0136] Optionally, after responding to the first message from the first device, the second device may further include the following steps:

[0137] 8. The second device sends a second indication to the network device. The second indication information is used to instruct the first device to enter the DRX sleep state. Alternatively, the first device may determine that the first device enters the DRX sleep state when a first timer of the first device times out.

[0138] The second indication information may also be UCI. Its specific indication method is similar to the first indication information, except that it indicates that the first device enters the DRX sleep state. The UCI sent in the second indication information also includes the address information of the first device, and a bit may be added to the information to indicate the DRX sleep state of the first device. In this case, a bit may also be added to the first indication information to indicate the DRX sleep state of the first device. For example, 1 may be used to indicate active, and 0 may be used to indicate dormant.

[0139] Optionally, the priority of the UCI is the same as the priority of the first message.

[0140] The second implementation is to add a DRX configuration identifier (DRX_configuration_ID) parameter to distinguish the first device configured for DRX in sidelink communication with the second device. That is, each device maintains the DRX_configuration_ID parameter and includes it in the report message to indicate to the network that the device is in the DRX active state. The specific steps are as follows:

[0141] 1. The first device sends a first message that requires a reply to the second device. The first message may be: physical layer information; MAC CE information, such as CSI report scheduling information; RLC layer information, such as RLC status report scheduling information; PDCP layer information; RRC signaling, such as UE capability acquisition information, measurement report scheduling information, RRC reconfiguration information, etc.

[0142] After sending the first message to the second device, the first device starts the RTT timer.

[0143] 2. The first device enters the DRX active state and prepares to receive a reply message from the second device, that is, a second message in response.

[0144] The active state is indicated by the INACTIVE timer, and the INACTIVE timer starts after the RTT timer expires.

[0206] The method for indicating the status of the device in the side link provided in any of the aforementioned embodiments is an explanation of the unicast scenario. For the multicast scenario, the technical solution provided in this application is also applicable. Specifically, the first device can send a first message that requires a reply to multiple second devices in the group at the same time. For the multiple second devices in the group that receive the first message, they can report to the network device through the solutions provided in the aforementioned embodiments, so as to obtain the side link transmission resources in time and respond to the message sent by the first device. For the first device, before the INACTIVE timer expires, if the first device receives responses from all multiple second devices, the INACTIVE timer is stopped, otherwise it is considered that the transmission with the unresponsive second device has failed.

[0207] These second devices may also report to the network device that the first device is in the DRX sleep state, which is not limited in this solution.

[0208] Figure 6 A schematic diagram of a multicast scenario in a side link provided in an embodiment of the present application is shown in FIG.

Devices 1 through 4 can report to the network device according to the solution provided in the previous embodiment to obtain sidelink transmission resources and respond to device 0. As shown in the figure, device 0 successfully receives the response messages from devices 1 and 3 and replies successfully. However, devices 2 and 4 do not, so device 0 can assume that the transmission between them and devices 2 and 4 has failed.

[0209] The various embodiments of the present application provide a method for indicating the device status in the side link, and provide a method for reporting the DRX status of the other party's device to the network in the side link power saving mechanism, so that the network can fully understand the DRX status of the other party's device, so that the Rx device can obtain the sending resources in time when it needs to respond to the message from the Tx device, thereby avoiding or reducing the problem of transmission failure.
