Description

[0001] This application claims priority to Chinese patent application No. 202010739294.5, filed on July 28, 2020, and entitled “A method and terminal for providing auxiliary information”, 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 an information configuration method, device and system. Background Art

[0003] With the development of communication technology, the Internet of Things technology has also developed rapidly. At present, the sidelink (SL) has been introduced into the Internet of Things technology to support direct communication between terminals. Based on sidelink communication, two terminals can send data directly without sending the data to the network device first and then forwarding it by the network device, thereby greatly reducing the data delay. In sidelink communication, relevant information needs to be configured for the terminal in advance.

[0004] In some communication scenarios of sidelink communication, the terminal can autonomously select the sidelink resources for data transmission in the sidelink. In this communication scenario, it is necessary to pre-configure a perception window for the terminal so that the terminal performs a sensing operation within the perception window to determine the available sidelink resources required for the data. Among them, the window area of ​​the perception window is a period of time. The sensing operation refers to collecting perception information, determining the channel occupancy status based on the perception information, and determining the available sidelink resources based on the channel occupancy status. Among them, the perception information includes channel measurement information, etc.

[0005] On this basis, discontinuous reception (DRX) technology is also introduced in sidelink communication, so that the terminal can switch between active state and sleep state, thereby reducing the power consumption of the terminal. After the introduction of DRX technology, it is necessary to configure the DRX cycle for the terminal additionally, and the DRX cycle includes an activation window and a sleep window. The terminal is in an active state within the activation window, and senses the physical downlink control channel (PDCCH) or the physical sidelink control channel (PSCCH). The terminal is in a sleep state within the sleep window, and does not sense or receive downlink signals to save power consumption. Among them, the window areas of the activation window and the sleep window are both time resources. When the terminal is in a sleep state, it cannot perform the sensing operation because it cannot detect the physical sidelink shared channel-reference signal receiving power (PSSCH-RSRP) and the received signal strength indication (RSSI) measurement.

[0006] Since the sensing window and the sleep window of the terminal are configured separately, the configured sensing window and the sleep window may conflict, that is, the window areas of the sensing window and the sleep window overlap. In this case, the terminal will not know whether to perform the sensing operation or be in the sleep state. Summary of the invention

[0007] The present application provides an information configuration method and device, which can be used to solve the problem of conflict between a sensing window and a sleep window in the related art.

[0008] In order to solve the above technical problems, the embodiments of the present application provide the following technical solutions:

[0009] In a first aspect, an information configuration method is provided, which is applied to a communication device, including: the communication device generates first configuration information and sends the first configuration information. The first configuration information is used to indicate a conflict resolution strategy when a sleep window conflicts with a perception window. The sleep window refers to a time resource that needs to be in a discontinuous reception sleep state, and the perception window refers to a time resource that needs to perform a perception operation.

[0010] In an embodiment of the present application, by sending the first configuration information to configure the conflict resolution strategy when the sleep window and the perception window conflict, the terminal that receives the first configuration information can execute the corresponding conflict resolution strategy when the sleep window and the perception window conflict, thereby solving the problem of not knowing whether to perform the perception operation or stay in the sleep state when the sleep window and the perception window conflict, thereby reducing the power consumption overhead of the device while ensuring the smooth progress of data services.

[0011] It should be noted that the conflict resolution strategy is a strategy for resolving conflicts between the sleep window and the perception window, and may be operation-related information of operations to be performed when conflicts occur between the sleep window and the perception window. The time resources of the sleep window and the perception window include time domain resources and / or frequency domain resources.

[0012] It should also be noted that the sleep window and the perception window can be configured through configuration information, or can be configured through standard regulations or negotiated by the communication device and the terminal. The embodiment of the present application does not limit the configuration method of the sleep window and the perception window. For example, the communication device can configure the DRX cycle for the terminal by sending DRX configuration information. The DRX configuration information includes the DRX cycle, and the DRX cycle includes the activation window and the sleep window.

[0013] Optionally, sending the first configuration information may include one or more of the following methods:

[0014] The first implementation method: before sending the DRX configuration information or the perception window configuration information, send the first configuration information.

[0015] As an example, the first configuration information may be sent via RRC, MAC CE, or SCI before sending the DRX configuration information or the perception window configuration information.

[0016] It should be noted that the DRX configuration information is used to indicate the sleep window, and the sensing window configuration information is used to indicate the sensing window. For example, the sensing window configuration information includes one or more of the sensing window period, the time resource size information of the sensing window, and the resource location information.

[0017] That is, in the first implementation, the first configuration information may be configured separately before configuring the sleep window or the perception window, thereby avoiding changes to the sleep window or the perception window configuration process and increasing reliability.

[0018] The second implementation method: sending second configuration information, where the second configuration information includes the first configuration information and one or more of the following information: DRX configuration information, or perception window configuration information.

[0019] As an example, the first configuration information may be carried in the DRX configuration information and sent, or the first configuration information may be carried in the perception window configuration information and sent, or the second configuration information carrying the first configuration information, the DRX configuration information and the perception window configuration information may be sent.

[0020] That is, in the second implementation, the first configuration information may be sent via DRX configuration information and / or perception window configuration information, thereby reducing signaling overhead.

[0021] The third implementation method: before sending the DRX configuration information or the perception window configuration information, send the first sub-information; send the third configuration information, the third configuration information includes the second sub-information and one or more of the following information: DRX configuration information, or perception window configuration information.

[0022] The first sub-information is a part of the first configuration information, and the second sub-information is another part of the first configuration information.

[0023] That is, a part of the first configuration information is sent separately outside the DRX configuration information or the perception window configuration information, and another part of the first configuration information is sent through the DRX configuration information or the perception window configuration information. In this way, the flexibility of information configuration can be increased.

[0024] Optionally, the first configuration information includes one or more of the following information:

[0025] The first type of information: perception operation indication information, which is used to instruct to perform a perception operation within a target sleep window, where the target sleep window refers to all or part of the sleep windows that conflict with the perception window.

[0026] That is, in the first type of information, the sensing operation indication information may indicate that when a conflict occurs between the sleep window and the sensing window, the sensing operation is performed in the target sleep window without putting the device in the sleep state.

[0027] By using the first type of information, the target sleep window can be converted into a perception window without performing the function of the sleep window, thereby avoiding the conflict between the perception operation in the target sleep window and the sleep state.

[0028] The second type of information: indication information of a sub-window, where the sub-window is a window associated with a target sleep window; a perception operation needs to be performed in the sub-window associated with the target sleep window, and windows other than the sub-window in the target sleep window need to be in a sleep state; or, a sub-window associated with the target sleep window needs to be in a sleep state, and a perception operation needs to be performed in windows other than the sub-window in the target sleep window.

[0029] It should be noted that the sub-window is a window associated with part or all of the target dormant window. For example, the sub-window is part or all of the target dormant window, or is a window overlapping part or all of the target dormant window.

[0030] In a possible implementation manner, the indication information of the sub-window is used to indicate the sub-window.

[0031] In another possible implementation, the indication information of the sub-window is used to indicate the sub-window, and is also used to indicate that the sub-window associated with the target sleep window is in a sleep state, and that a perception operation is performed in a window other than the sub-window in the target sleep window, or that the sub-window associated with the target sleep window is in a sleep state, and that a perception operation is performed in a window other than the sub-window in the target sleep window.

[0032] As an example, the indication information of the subwindow may be the resource location information of the subwindow, used to indicate the time resource where the subwindow is located. Alternatively, the indication information of the subwindow may be the location information of the subwindow in the target sleep window, used to indicate the location of the subwindow in the target sleep window.

[0033] By using the second type of information, the device that receives the indication information of the sub-window can perform the perception operation in a part of the target sleep window and be in a sleep state in another part of the target sleep window, thereby avoiding the conflict between the perception operation in the target sleep window and being in a sleep state.

[0034] In a possible implementation manner, the first configuration information may further include first window indication information or second window indication information.

[0035] The first window indication information is used to indicate that the sub-window is a perception sub-window, that is, to indicate that a perception operation is performed in the sub-window associated with the target sleep window and that windows other than the sub-window in the target sleep window are in a sleep state.

[0036] The second window indication information is used to indicate that the sub-window is a dormant sub-window, that is, to indicate that the sub-window associated with the target dormant window is in a dormant state and that a sensing operation is performed in windows other than the sub-window in the target dormant window.

[0037] The third type of information: indication information of available sidelink resources, where the indication information of available sidelink resources is used to indicate the sidelink resources required for data transmission configured when the target sleep window is in a sleep state.

[0038] It should be noted that the available sidelink resources may include time domain resources and / or frequency domain resources for transmitting data.

[0039] By using the third type of information, available sidelink resources can be reserved for the terminal through the first configuration information, so that the terminal can be in sleep state within the target sleep window without performing perception operations, and can also transmit data based on the reserved available sidelink resources to ensure the smooth progress of data services.

[0040] Optionally, the indication information of the sub-window includes one or more of the following information:

[0041] The first type of information: the window size information of the sub-window, the starting position of the sub-window is the starting position of the target dormant window, or the ending position of the sub-window is the ending position of the target dormant window.

[0042] In the first type of information, the sub-window is a front portion of the window or a back portion of the window in the target dormant window.

[0043] It should be noted that the window size information of the sub-window is used to indicate the window size of the sub-window. The window size of the sub-window may include the size of the sub-window in the time domain and / or the size of the sub-window in the frequency domain.

[0044] It should also be noted that whether to use the starting position of the target sleep window as the starting position of the sub-window, or to use the ending position of the target sleep window as the ending position of the sub-window, can be determined by standard regulations or negotiated in advance by the communication device and the terminal, or can be configured through configuration information, and the embodiments of the present application do not limit this.

[0045] As an example, the indication information of the sub-window may include first indication information or second indication information in addition to the window size information of the sub-window. The first indication information is used to indicate the starting position of the sub-window, and the starting position of the sub-window is the starting position of the target dormant window. The second indication information is used to indicate the end position of the sub-window, and the end position of the sub-window is the end position of the target dormant window.

[0046] The second type of information: the starting position information and the ending position information of the subwindow.

[0047] In the second information, the sub-window is a part of the window or the whole window in the target sleep window, and may be a window in the front part or the back part of the target sleep window, or a window in the middle part of the target sleep window.

[0048] The starting position information and the ending position information of the sub-window are used to determine the time resource where the sub-window is located. As an example, the starting position information and the ending position information of the sub-window may include time domain position information and / or frequency domain position information. As another example, the starting position information and the ending position information of the sub-window may also be the starting position information and the ending position information of the sub-window in the target sleep window.

[0049] The third type of information: In the third type of information, the sub-windows are multiple windows spaced apart from each other in the target dormant window. The indication information of the sub-windows includes the starting position information of the first window among the multiple windows, the ending position information of the last window, and the spacing rule of the multiple windows.

[0050] It should be noted that the starting position information of the first window and the ending position information of the last window may include time domain position information and / or frequency domain position. Alternatively, the starting position information of the first window may be the starting position information in the target sleep window, and the ending position information of the last window may be the ending position information in the target sleep window.

[0051] In addition, the spacing rule of multiple windows is used to indicate how the multiple windows are spaced apart. For example, the spacing rule of multiple windows may include window size information of each window in the multiple windows and window size information of the intervals between the windows.

[0052] In one embodiment, the spacing rule of multiple windows can be the window indication information of each resource unit in the multiple resource units included in the target window. The target window refers to the window between the starting position of the first window and the ending position of the last window. The target window includes multiple resource units, and the window indication information of the resource unit is used to indicate whether the resource unit belongs to a subwindow.

[0053] The resource unit may include a time domain unit and / or a frequency domain unit. For example, the resource unit may be a subframe or a time slot in the time domain. For example, if the window indication information of a resource unit is 1, it indicates that the time resource where the resource unit is located belongs to the subwindow; if the window indication information of a resource unit is 0, it indicates that the time resource where the resource unit is located does not belong to the subwindow.

[0054] Optionally, if the first configuration information includes indication information of available sidelink resources, before sending the first configuration information, an auxiliary perception operation may be performed to obtain indication information of available sidelink resources, and then the first configuration information including the indication information of available sidelink resources may be sent.

[0055] That is, the communication device can determine the available sidelink resources required for the data by performing the auxiliary sensing operation, and configure the determined available sidelink resources to the terminal to reserve the available sidelink resources for the terminal. In this way, the availability of the available sidelink resources can be guaranteed.

[0056] In a second aspect, an information configuration device is provided, wherein the information configuration device has the function of implementing the information configuration method in the first aspect. The information configuration device includes at least one module, wherein the at least one module is used to implement the information configuration method provided in the first aspect.

The target sleep window refers to part or all of the sleep windows of the terminal that conflict with the perception window of the terminal.

[0064] In an embodiment of the present application, by receiving first configuration information, a corresponding conflict resolution strategy is executed based on the first configuration information when a conflict occurs between the sleep window and the perception window, thereby solving the problem of not knowing whether to perform a perception operation or remain in a sleep state when a conflict occurs between the sleep window and the perception window, thereby reducing the power consumption overhead of the device and ensuring the smooth progress of data services.

[0065] Optionally, receiving the first configuration information includes the following implementations:

[0066] The first implementation method: before receiving the DRX configuration information or the perception window configuration information, the first configuration information is received separately.

[0067] It should be noted that the DRX configuration information is used to indicate the sleep window, and the perception window configuration information is used to indicate the perception window.

[0068] A second implementation method is to receive second configuration information, where the second configuration information includes the first configuration information and an indication of one of the following configuration information: DRX configuration information, or perception window configuration information.

[0069] That is, the second configuration information may be received, and the first configuration information may be acquired from the second configuration information.

[0072] That is, a part of the information in the first configuration information is received separately, and another part of the information in the first configuration is received through the DRX configuration information or the perception window configuration information.

[0073] It should be noted that the terminal can receive the first configuration information sent by the communication device in a directionally manner, and can also receive the first configuration information sent by the communication device in an undirected manner, such as receiving the first configuration information broadcast by the communication device through an antenna. The embodiment of the present application does not limit the manner in which the terminal receives the first configuration information.

[0074] Optionally, based on the first configuration information, executing the conflict resolution strategy in the target sleep window includes the following situations:

[0075] The first case: if the first configuration information includes perception operation indication information, the perception operation is performed within the target sleep window based on the first configuration information.

[0076] That is, the sensing operation is performed within the target sleep window without being in the sleep state, thereby avoiding the conflict between the sensing operation within the target sleep window and being in the sleep state.

[0077] The second case: If the first configuration information includes indication information of a sub-window, the perception operation is performed in the sub-window of the target sleep window, and the window other than the sub-window in the target sleep window is in a sleep state; or, the window is in a sleep state in a sub-window determined in the target sleep window, and the perception operation is performed in the window other than the sub-window in the target sleep window.

[0078] That is, the sensing operation is performed in a part of the target sleep window, and the device is in a sleep state in another part of the target sleep window, thereby avoiding the conflict between the sensing operation in the target sleep window and the sleep state.

[0079] It should be noted that, based on standard regulations, rules negotiated in advance with the communication device, or relevant information carried by the first configuration information, it can be determined whether to perform the perception operation in a sub-window of the target sleep window and be in a sleep state in a window other than the sub-window, or to be in a sleep state in a sub-window of the target sleep window and perform the perception operation in a window other than the sub-window.

[0080] In a possible implementation, if the first configuration information also includes first window indication information, the terminal can perform a sensing operation in a sub-window determined from the target sleep window based on the indication information of the sub-window, and be in a sleep state in a window other than the sub-window in the target sleep window. If the first configuration information also includes second window indication information, the terminal can be in a sleep state in a sub-window determined from the target sleep window based on the indication information of the sub-window, and perform a sensing operation in a window other than the sub-window in the target sleep window.

The second window indication information is used to indicate that the sub-window is a sleep sub-window, that is, to indicate that the sub-window associated with the target sleep window is in a sleep state, and that the perception operation is performed in the windows other than the sub-window in the target sleep window.

[0082] The third case: the first configuration information includes indication information of available sidelink resources, the device is in a sleep state within a target sleep window, and data transmission is performed based on the available sidelink resources.

[0083] That is, the reserved available sidelink resources can be determined based on the first configuration information, so that even if the sensing operation cannot be performed in the target sleep window, there are available sidelink resources for data transmission, thereby ensuring the smooth progress of data services.

[0084] Optionally, in the case where the first configuration information includes indication information of the sub-window, the sub-window may also be determined from the target sleep window based on the indication information of the sub-window.

[0085] In a possible implementation, based on the indication information of the sub-window, the sub-window is determined from the target dormant window, including the following situations:

[0086] The first case: when the indication information of the sub-window includes window size information, based on the window size information, the sub-window is determined from the target sleep window with the start position of the target sleep window as the start position or the end position of the target sleep window as the end position.

[0087] The second case: when the indication information of the sub-window includes the starting position information and the ending position information, the sub-window is determined from the target sleep window based on the starting position information and the ending position information.

[0088] The third situation: the indication information of the sub-window includes the starting position information of the first window among the multiple windows spaced apart from each other, the ending position information of the last window, and the spacing rule of the multiple windows. Based on the starting position information of the first window, the ending position information of the last window, and the spacing rule of the multiple windows, the multiple windows are determined from the target dormant window, and the multiple windows are used as sub-windows.

[0089] In a possible implementation, if the interval rule of multiple windows is the window indication information of each resource unit in the multiple resource units included in the target window, the target window refers to the window between the starting position of the first window and the ending position of the last window, and the window indication information of each resource unit is used to indicate whether each resource unit belongs to a subwindow, then multiple windows can be determined from the target window based on the window indication information of each resource unit in the multiple resource units included in the target window. The target window can be determined based on the starting position information of the first window and the ending position information of the last window.

[0090] In an embodiment of the present application, the indication information of the sub-window may include different information forms. By determining the sub-window based on the indication information of different sub-windows, the flexibility and usability of configuring the sub-window can be improved, and it can be applicable to different information configuration scenarios.

The memory 203 may exist independently and be connected to the processor 201 via the communication bus 202. The memory 203 may also be integrated with the processor 201.

[0135] The transceiver 204 uses any transceiver-like device for communicating with other devices or communication networks, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.

[0136] In a specific implementation, as an embodiment, the processor 201 may include one or more CPUs, such as Figure 2 CPU0 and CPU1 are shown in the figure.

[0137] In a specific implementation, as an embodiment, the communication device may include multiple processors, such as Figure 2 201 and processor 205 shown in FIG. Each of these processors may be a single-core processor or a multi-core processor.

The embodiment of the present application does not limit the type of the communication device.

[0140] The memory 203 is used to store the program code 210 for executing the solution of the present application, and the processor 201 is used to execute the program code 210 stored in the memory 203. The communication device can implement the following by means of the processor 201 and the program code 210 in the memory 203: Figure 7 The information configuration method provided by the embodiment.

[0141] The information configuration method provided in the embodiment of the present application can be applied to sidelink communication scenarios, such as sidelink communication scenarios in the Internet of Things. In sidelink communication, data can be sent directly between two terminals without first sending the data to a network device and then forwarding it by the network device, thereby greatly reducing data latency.

[0142] The sidelink communication may be sidelink communication based on LTE, sidelink communication based on 5G NR, or sidelink communication based on other communication networks, which is not limited in the embodiments of the present application.

[0143] Sidelink communication scenarios such as Figure 3 As shown, Figure 3 is a schematic diagram of a communication system provided by an embodiment of the present application, the system comprising: a transmitter terminal (Tx terminal) 10, a receiver terminal (Rx terminal) 20, and a terminal 30. It should be understood that Figure 3 A transmitting terminal 10, a receiving terminal 20, and a terminal 30 are shown.

[0144] The receiving terminal 20 in the embodiment of the present application refers to a terminal capable of receiving service data sent by the sending terminal 10. Of course, the receiving terminal 20 can send service data in addition to receiving service data. The sending terminal 10 refers to a terminal capable of sending service data. Of course, the sending terminal 10 can also receive service data sent by other devices (such as the terminal 30 or the network device 40) in addition to sending service data. The sending terminal and the receiving terminal are relative concepts.

[0145] It can be understood that in the embodiment of the present application, the sending terminal 10 and the receiving terminal 20 are capable of sidelink communication, and one or more of the sending terminal 10 or the receiving terminal 20 adopts a power saving mode, that is, the sending terminal 10 or the receiving terminal 20 switches between a sleep state and an active state within a cycle.

[0146] The terminal 30 is used to configure a DRX configuration for the transmitting terminal 10 or the receiving terminal 20, and / or to sense a time resource (a sense window) of a sidelink resource. Figure 3 In the example, the receiving terminal 20 and the sending terminal 10 communicate with the same terminal 30. In the actual process, the DRX configuration is configured for the receiving terminal 20 and the sending terminal 10, and / or the terminals used to perceive the time resources of the sidelink resources may also be different terminals. For example, the terminal 30 configures the DRX configuration for the sending terminal 10, and / or, the time resources for perceiving the sidelink resources. For example, the terminal 30 configures the DRX configuration for the receiving terminal 20, and / or, the time resources for perceiving the sidelink resources. It is worth noting that the terminal configured with the DRX configuration for the receiving terminal 20 (or the sending terminal 10) and the terminal configured with the time resources for perceiving the sidelink resources may be the same terminal or different terminals, and the embodiments of the present application do not limit this.

[0147] It is worth noting that, when the DRX configuration of the receiving terminal 20 and / or the time resources for sensing the sidelink resources are configured by the transmitting terminal 10, the terminal 30 may be omitted.

[0148] In a possible implementation, the communication system may further include: a network device 40. A second interface (e.g., a Uu interface) is provided between the network device 40 and the sender terminal 10, the receiver terminal 20, and the terminal 30. The user plane of the Uu interface mainly transmits user data; the control plane transmits related signaling, establishes, reconfigures, and releases various mobile communication radio bearer services.

[0149] The network device 40 is used to configure the DRX configuration (e.g., sleep window and activation window) for the sender terminal 10 or the receiver terminal 20, and / or, for the time resource of the sidelink resource. When the network device 40 is included in the communication system, if the time resource and DRX configuration of the sender terminal 10 (or the receiver terminal 20) for sensing the sidelink resource are configured by the network device 40, then the terminal 30 can also be omitted. Of course, when the network device 40 is included in the communication system, if the DRX configuration of the sender terminal 10 (or the receiver terminal 20) is configured by the network device 40, then the time resource of the sensing sidelink resource of the sender terminal 10 (or the receiver terminal 20) can be configured by the terminal 30, and the terminal 30 needs to be reserved. Of course, the terminal 30 can also configure the DRX configuration for the sender terminal 10 (or the receiver terminal 20), and the network device 40 configures the time resource of the sensing sidelink resource for the sender terminal 10 (or the receiver terminal 20), and the embodiment of the present application does not limit this. The sender terminal 10 and the receiver terminal 20 can access different network devices. Figure 1 In the example, the two devices are connected to the same network device.

[0150] Among them, there is a first interface for direct communication between the sender terminal 10 and the receiver terminal 20, the sender terminal 10 and the terminal 30, or the receiver terminal 20 and the terminal 30, and the first interface can be called a PC5 interface. The transmission link on the PC5 interface for communication between terminals can be called a side link. For example, the PC5 interface can use a dedicated frequency band (such as 5.9GHz).

[0151] In order to improve the safety and intelligence of the traffic system, the system concept of intelligent transportation is gradually emerging. In the near future, the development of intelligent transportation systems will focus on the field of intelligent highway traffic systems, which is commonly known as vehicle to everything (V2X). V2X communication includes vehicle to vehicle (V2V) communication, vehicle to roadside infrastructure (V2I) communication and vehicle to pedestrian (V2P) communication. V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, and improve traffic efficiency. For example, communication with facilities such as traffic lights, campuses and railway crossings. The vehicle networking system is a sidelink transmission technology based on long-term evolution (LTE) V2V or new air interface V2V. Unlike the traditional LTE system or NR in which communication data is received or sent through network equipment, the vehicle networking system adopts terminal-to-terminal direct communication.

[0152] With the evolution of communication technology, the 3rd generation partnership project (3GPP) introduced support for V2V sidelink and V2X sidelink services in LTE during Release 14 and Release 15 to expand the 3GPP platform to other IoT industries such as automobiles. In addition, LTE V2X is supplemented by New Air Interface V2X to achieve advanced V2X services and support interoperability with LTE V2X.

[0153] Please refer to Figure 4 , Figure 4 : is a V2X sidelink architecture diagram provided in an embodiment of the present application. Figure 4 As shown in the figure, the V2X sidelink architecture is divided into two types: independent deployment and dual connection deployment, covering the following scenarios. Figure 4 Figure (a) in Figure 4 Figure (b) in Figure 4 Figure (c) in Figure 4 Figure (d) in Figure 4 Figure (e) and Figure 4 Figure (f) in the figure corresponds to scenario 1, scenario 2, scenario 3, scenario 4, scenario 5 and scenario 6. Among them, scenario 1-scenario 3 are independent deployment scenarios, and scenario 4-scenario 6 are dual-connectivity deployment scenarios, that is, multi-radio access technology dual connectivity (MR-DC) scenarios.

[0154] Among them, independent deployment refers to the working mode in which the terminal is connected to one base station, such as the working mode in which the terminal is connected to one 4G base station or one 5G base station in scenarios 1-3. Dual-connection deployment refers to the working mode in which the terminal is connected to two base stations, such as the working mode in which the terminal is connected to one 4G base station and one 5G base station in scenarios 4-6. Multi-radio access technology (MR) refers to multiple radio access technologies, such as evolved-UTRA (E-UTRA) and NR.

[0155] like Figure 4 As shown, in scenario 1, the terminal ( Figure 4The vehicle equipment or vehicle-mounted terminal in the vehicle shown in the figure accesses the 5G core network (5G core network, 5GC) through NR and connects to the new radio node B (NR node B, gNB) to implement NR V2X SL and LTE V2X SL. In scenario 2, the terminal accesses 5GC through E-UTRA and connects to the next generation evolved node B (next generation-evolved node B, ng-eNB) to implement NR V2X SL and LTE V2X SL. In scenario 3, the terminal accesses the evolved packet core network (evolved packe core, EPC) through E-UTRA and connects to the evolved node B (evolved node B, eNB) to implement NR V2X SL and LTE V2X SL. In scenarios 1-3, the gNB, ng-eNB and eNB respectively manage or configure the terminals performing V2X communication in LTE Sidelink and NR Sidelink.

[0156] In actual process, the terminal may access multiple network devices (eg, a primary base station or a secondary base station).

[0157] Among them, the primary base station can be the first base station that the terminal accesses during the random access process. The primary base station is responsible for establishing a control plane connection with the core network control plane entity, transmitting signaling messages, and deciding whether to create a secondary base station for the terminal. In addition, the primary base station can also select a secondary base station for the terminal. The primary base station supports the signaling plane access management of the terminal and the diversion of the user plane.

[0158] The secondary base station can be a second base station other than the primary base station, and is used to provide additional wireless resources for the terminal. There may be no direct control plane connection between the secondary base station and the core network control plane entity. The secondary base station supports user plane offloading of the terminal.

[0159] In one example, in an embodiment of the present application, the secondary base station and the primary base station may be base stations of the same network standard. For example, the network standards corresponding to the secondary base station and the primary base station are respectively evolved Node Bs (evolved Node B, eNB or eNodeB) in a 4G system. For another example, the network standards corresponding to the secondary base station and the primary base station may both be the next generation Node B (The Next Generation Node B, gNB) in an NR system.

[0160] In another example, the secondary base station and the primary base station in the embodiment of the present application may be base stations of different network standards. For example, the network standard corresponding to the primary base station is the eNB in ​​the 4G system, and the network standard corresponding to the secondary base station is the gNB in ​​the NR system. Alternatively, the network standard corresponding to the primary base station is the gNB under the NR system, and the network standard corresponding to the secondary base station is the eNB under the 4G system.

[0161] like Figure 4 As shown, in scenario 4, the terminal is connected to the main gNB (MgNB) and the secondary eNB (SeNB) respectively to implement NR V2X SL and LTE V2X SL. In scenario 5, the terminal is connected to the main eNB (MeNB) and the secondary eNB (SgNB) respectively to implement NR V2X SL and LTE V2X SL. In scenario 6, the terminal is connected to the main node (MN) and the secondary node (SN) respectively to implement NR V2X SL and LTE V2X SL. In scenarios 4-6, the main node manages or configures the terminal performing V2X communication in LTE sidelink and NR sidelink.

[0162] When the various solutions described in the embodiments of the present application can be applied to V2X scenarios, they can be applicable to the following fields: unmanned driving, automated driving (ADS), driver assistance (ADAS), intelligent driving, connected driving, intelligent network driving, and car sharing. Of course, the various solutions described in the embodiments of the present application can also be applied to the interaction between a bracelet and a mobile phone, or between VR glasses and a mobile phone.

[0163] NR can support unicast, multicast and broadcast transmission of sidelink within coverage, outside coverage and in partial coverage situations. Unicast refers to a one-to-one communication mode between terminals, that is, one terminal communicates with another specific terminal. Multicast refers to a one-to-group communication mode between terminals, that is, one terminal communicates with a group of terminals. Broadcast refers to a one-to-all communication mode between terminals, that is, one terminal communicates with all other terminals. In sidelink communication, the physical channels used for transmission include the physical sidelink control channel (PSCCH), the physical sidelink shared channel (PSSCH) and the physical sidelink feedback channel (PSFCH).

[0164] It should be noted that in communication networks such as NR, sidelink needs to transmit data based on resource pools. Resource pool is a logical concept. A resource pool includes multiple resources, including one or more time domain resources and frequency domain resources. Any resource in the resource pool is used to transmit data. When the terminal performs data transmission, it is necessary to first determine the sidelink resource from the resource pool, and then perform data transmission based on the determined sidelink. There are mainly two ways to determine resources: one is that the terminal is controlled by the network device, and according to the instruction information of the network device, a resource is selected from the resource pool as a sidelink resource for data transmission; the other is that the terminal autonomously selects a resource from the resource pool randomly as a sidelink resource for data transmission. Among them, the sidelink resource can be a resource for sending data or a resource for receiving data.

[0165] As an example, the resource determination method includes the following two methods:

[0166] Mode 1 (mode1), resource allocation mode of network scheduling.

[0167] Mode 1: When the terminal is in a radio resource control (RRC) connection state and performs data transmission with a network device, the network device communicating with the terminal can schedule sidelink resources for the terminal for transmitting sidelink service data. For example, the terminal sends a scheduling request (SR) and a sidelink buffer status report (BSR) to the network device. The sidelink BSR is used to determine the amount of sidelink communication data of the terminal. Based on the sidelink BSR, the network device can determine the amount of sidelink communication data of the terminal and schedule the sidelink resources required for the terminal to transmit sidelink service data. The network device uses the configured sidelink radio network temporary identity (SL-radio network temporary identity, SL-RNTI) to schedule sidelink resources for sidelink communication.

[0168] Mode 2 (mode2): resource selection mode selected by the terminal independently.

[0169] Mode 2, the terminal selects sidelink resources from a resource pool (usually including one or more sidelink resources). For example, when the terminal is within the coverage of the network, the resource pool is the resource broadcast by the network device in the system information. When the terminal is outside the coverage of the network, the resource pool is the resource preconfigured for the terminal. The resource pool may be a specific resource pool for the terminal, that is, only the terminal can select sidelink resources in the resource pool. Or the resource pool may be a resource pool shared by multiple terminals including the terminal, that is, the remaining terminals except the terminal can also select resources in the resource pool. For the latter, when the terminal autonomously selects resources in the resource pool, the terminal can perform perception of the resource pool to select sidelink resources.

[0170] In the case where the terminal autonomously selects resources for data transmission, the terminal can determine the transmission resources required for the data by performing a sensing operation. The sensing operation can be implemented using transmit sensing (TX sensing) technology. In the scenario where the transmission resources required for the data are determined by the sensing operation, it is usually necessary to pre-configure a sensing window for the terminal so that the terminal performs the sensing operation within the sensing window.

[0171] As an example, the information configuration method provided in the embodiment of the present application can be applied to mode 2 of sidelink communication. In mode 2, the terminal autonomously selects resources for data transmission. For example, the available sidelink resources required for data are determined by performing a sensing operation within a sensing window.

[0172] Among them, the sensing operation refers to collecting sensing information, determining the channel occupancy status according to the sensing information, and determining the available sidelink resources based on the channel occupancy status. Among them, the sensing information includes channel measurement information, etc. The channel measurement information may include the reference signal receiving power (RSRP) and received signal strength indication (RSSI) of PSSCH, etc.

[0173] As an example, see Figure 5 , Figure 5 is a schematic diagram of a sensing operation provided by an embodiment of the present application, such as Figure 5 As shown, the sensing operation may include the following steps:

[0174] Step 501: Collect perception information, where the perception information includes channel measurement information such as PSSCH-RSRP and RSSI.

[0175] Step 502: Based on the perception information, high-energy resources are excluded from the optional resources to form a candidate resource set.

[0176] Step 503: Select resources from the candidate resource set as available sidelink resources, and perform data transmission on the available sidelink resources.

[0177] Step 504: Determine whether to reselect resources.

[0178] If resource reselection is required, the process returns to step 501 to continue collecting sensing information, so as to exclude high-energy resources from the selectable resources based on the sensing information, form a candidate resource set, and then select an available sidelink resource from the resource candidate set. If resource reselection is not required, the process returns to step 503 to continue using the available sidelink resource selected in step 503 for data transmission, that is, data transmission is performed on the same sidelink resource in step 503.

[0179] This application can refer to the process of the terminal performing the sensing operation. Figure 5 Description.

[0180] At present, DRX technology is introduced in sidelink communication to reduce the power consumption of terminals. DRX technology means that the terminal only turns on the receiver to enter the active state when necessary to receive downlink data and signaling, and turns off the receiver to enter the dormant state at other times to stop receiving downlink data and signaling. This is a working mode that saves terminal power consumption.

[0181] In a wireless network, when data needs to be transmitted, the terminal must always monitor the PDCCH and send and receive data according to the instruction message sent by the network side, which will lead to large power consumption of the terminal and data transmission delay. Therefore, the 3GPP standard protocol introduced the DRX energy saving strategy in the LTE system, which is defined in the physical layer media access control (MAC).

[0182] Discontinuous reception (DRX) means that the terminal turns on the receiver to enter the activated state (also called the active state) only when necessary to receive downlink data and signaling. At other times, the receiver is turned off to enter the sleep state (also called the inactive state). When the terminal is in the sleep state, the terminal stops receiving downlink data and signaling. DRX is a working mode of the terminal that saves terminal power consumption. DRX is divided into idle state DRX and connected state DRX. Since idle state DRX has no RRC connection and terminal-specific bearer, it is achieved by sensing the paging channel. Connected state DRX refers to the DRX feature when the terminal is in the RRC connected state, which is achieved by monitoring the physical downlink control channel (PDCCH) or PSCCH. The schematic diagram of the DRX mechanism is shown in the figure Figure 6 As shown, in the time domain, time is divided into continuous DRX cycles (DRX cycles).

[0183] The DRX cycle includes an activation window and a sleep window. The activation window is also called the active period, and the activation window is timed by the DRX duration timer (drx-onDurationTimer). In the activation window, the terminal senses PDCCH or PSCCH. The sleep window is also called the inactive period. In the sleep window, the terminal does not sense or receive downlink signals to save power consumption. The DRX duration timer refers to: when the DRX cycle starts, the duration of on duration, during which the terminal is in an activated state (also called awake state). The DRX cycle can include a short DRX cycle and a long DRX cycle. A long DRX cycle is generally an integer multiple of a short DRX cycle. Please refer to Figure 6, Figure 6 This is a schematic diagram of a DRX cycle provided in an embodiment of the present application. Figure 6 Figure (a) shows a long DRX cycle. Figure 6 Figure (b) shows a short DRX cycle.

[0184] Typical application scenarios of DRX include: services that are not sensitive to latency and do not need to receive and send data most of the time, such as browsing web pages, receiving emails, and file transfer services based on file transfer protocol (FTP). Services that generate rare small packets, such as presence services. Periodic continuous small packet services, such as voice over internet protocol (VoIP) services. Automatic neighbor relation (ANR) measurement.

[0185] Since the perception window and sleep window of the terminal are configured separately, the configured perception window and sleep window may conflict, that is, the window areas of the perception window and the sleep window overlap. In this case, the terminal will not know whether to perform the perception operation or be in a sleep state, which may cause the terminal to be unable to perform the perception operation normally, and then be unable to perceive the available sidelink resources required for subsequent data transmission, resulting in data services being unable to proceed smoothly. In order to solve this problem, an embodiment of the present application provides a method for configuring a conflict resolution strategy for a terminal through configuration information, so that the terminal executes a corresponding conflict resolution strategy when a conflict occurs between the sleep window and the perception window, so as to solve the problem of the conflict between the sleep window and the perception window, thereby reducing the power consumption overhead of the terminal while ensuring the smooth progress of the data service.

[0186] The interactive subjects of the information configuration method provided in the embodiment of the present application are communication devices and terminals. The communication device can be a base station or a terminal in the above-mentioned sidelink communication scenario, and the terminal can be a terminal in the above-mentioned sidelink communication scenario.

[0187] Figure 7 1 is a flowchart of an information configuration method provided by an embodiment of the present application, wherein the interaction subjects of the method are a communication device and a terminal. The communication device is a device for configuring information, which may be a network device or a terminal, etc. The terminal is a device for configuring information. Figure 7 As shown, the method comprises the following steps:

[0188] Step 701: The communication device generates first configuration information, where the first configuration information is used to indicate a conflict resolution strategy when a conflict occurs between a sleep window and a perception window.

[0189] In an embodiment of the present application, in order to solve the problem that the terminal does not know which operation to perform when the sleep window and the perception window conflict, a method is proposed in which a communication device configures a conflict resolution strategy for the terminal through configuration information so that the terminal performs the corresponding conflict resolution strategy when the sleep window and the perception window conflict. Before configuring the conflict resolution strategy for the terminal, the communication device needs to generate first configuration information for indicating the conflict resolution strategy.

[0190] It should be noted that the conflict resolution strategy is a strategy for resolving the conflict between the sleep window and the perception window, and may be operation-related information of an operation that needs to be performed when the sleep window conflicts with the perception window.

[0191] The sleep window refers to the time resources that need to be in the sleep state, and the terminal is in the sleep state within the sleep window. For example, the sleep window can be configured through DRX configuration information. For example, the communication device or other devices outside the communication device configure the DRX configuration information for the terminal. Among them, the DRX configuration information is used to indicate the sleep window. For example, the DRX configuration information may include a DRX cycle, and the DRX cycle includes an activation window and a sleep window. Of course, the sleep window can also be specified by the standard or negotiated by the communication device and the terminal, and the embodiment of the present application does not limit the configuration method of the sleep window.

[0192] The perception window refers to the time resources required to perform the perception operation. The perception operation is used to determine the available sidelink resources required for the data. For example, the perception operation refers to collecting perception information, determining the channel occupancy status based on the perception information, and determining the available sidelink resources based on the channel occupancy status. The perception information includes channel measurement information, etc. Among them, the available sidelink resources include available sending resources or available receiving resources. The available sending resources are used to send data, and the available receiving resources are used to receive data. The available sidelink resources may include time domain resources and / or frequency domain resources.

[0193] The perception window can be configured through the perception window configuration information. For example, the communication device or other devices outside the communication device configure the perception window configuration information for the terminal. Among them, the perception window configuration information is used to indicate the perception window. For example, the perception window configuration information may include one or more of the perception window period, the time resource size information of the perception window, and the resource location information. Of course, it may also include other relevant information of the perception window, which is not limited in the embodiment of the present application. Of course, the perception window can also be specified by the standard or negotiated by the communication device and the terminal, and the embodiment of the present application does not limit the configuration method of the perception window.

[0194] In addition, time resources refer to resource regions composed of time domain resources and / or frequency domain resources. For example, time resources may include resource regions composed of a section of time domain resources and all frequency domain resources, or resource regions composed of a section of time domain resources and a section of frequency domain resources.

[0195] As an example, the first configuration information may include one or more of the following information:

[0196] The first type of information: perceptual operation instruction information.

[0197] It should be noted that the sensing operation indication information is used to indicate that the sensing operation is performed in the target sleep window. The target sleep window refers to part or all of the sleep windows that conflict with the sensing window. For example, the target sleep window refers to the sleep window that conflicts with the sensing window. Alternatively, the target sleep window refers to the part of the sleep window that conflicts with the sensing window, that is, the part of the sleep window that overlaps with the sensing window.

[0198] In the first type of information, the perception operation indication information may indicate that when a sleep window conflicts with a perception window, the perception operation is performed in the target sleep window without switching the device state to the sleep state.

[0199] In this way, the target sleep window can be converted into a sensing window without performing the function of the sleep window, thereby avoiding the conflict between the sensing operation in the target sleep window and the sleep state.

[0200] The second type of information: indication information of a child window, where the child window is a window in the target dormant window.

[0201] It should be noted that the indication information of the sub-window may be the resource location information of the sub-window, which is used to characterize the time resource where the sub-window is located. Alternatively, the indication information of the sub-window may be the location information of the sub-window in the target sleep window, which is used to characterize the location of the sub-window in the target sleep window. The indication information of the sub-window may include the indication information of the time domain and / or frequency domain of the sub-window.

[0202] The sub-window is a window associated with the target dormant window, specifically a window associated with part or all of the windows of the target dormant window. For example, the sub-window may be part or all of the windows in the target dormant window, or a window overlapping part or all of the windows in the target dormant window, etc. The configured sub-window may be a sensing sub-window that needs to perform a sensing operation, or a dormant sub-window that needs to be in a dormant state.

[0203] A sensing operation needs to be performed in the subwindow associated with the target sleep window, and the windows other than the subwindow in the target sleep window need to be in a sleep state; or, the subwindow associated with the target sleep window needs to be in a sleep state, and the windows other than the subwindow in the target sleep window need to be in a sleep state. For example, a sensing operation needs to be performed in the subwindow of the target sleep window, and the windows other than the subwindow in the target sleep window need to be in a sleep state; or, the subwindow in the target sleep window needs to be in a sleep state, and the windows other than the subwindow in the target sleep window need to be in a sleep state.

[0204] If the sub-window is a perception sub-window, the perception operation needs to be performed in the sub-window associated with the target sleep window, and the windows in the target sleep window other than the sub-window need to be in a sleep state. That is, the sub-window associated with the target sleep window is used as a perception window to perform the perception operation, and the other windows in the target sleep window are still used as sleep windows to be in a sleep state. In this way, the device that receives the indication information of the sub-window can perform the perception operation in a part of the window of the target sleep window, and be in a sleep state in another part of the window of the target sleep window, thereby avoiding the conflict between the perception operation in the target sleep window and being in a sleep state.

[0205] If the sub-window is a dormant sub-window, the sub-window associated with the target dormant window needs to be in a dormant state, and the windows other than the sub-window in the target dormant window need to perform a sensing operation. That is, the sub-window associated with the target dormant window is used as a dormant window to be in a dormant state, and the other windows in the target dormant window are used as sensing windows to perform a sensing operation. In this way, the device that receives the indication information of the sub-window can perform a sensing operation in a part of the window of the target dormant window and be in a dormant state in another part of the window of the target dormant window, thereby avoiding the conflict between the sensing operation in the target dormant window and being in a dormant state.

[0206] As an example, the indication information of the sub-window is used to indicate the sub-window. In addition, the action of the terminal that receives the indication information of the sub-window can be configured through other configuration information, standard regulations or advance negotiation, that is, the terminal that receives the indication information of the sub-window is configured to perform a perception operation in the sub-window associated with the target sleep window, and be in a sleep state in a window other than the sub-window in the target sleep window, or be in a sleep state in the sub-window associated with the target sleep window and perform a perception operation in a window other than the sub-window in the target sleep window.

[0207] As another example, the indication information of the sub-window can not only indicate the sub-window, but also indicate the action of the terminal that receives the indication information of the sub-window, that is, it can also be used to indicate performing a perception operation in a sub-window associated with the target sleep window, being in a sleep state in a window other than the sub-window in the target sleep window, or being in a sleep state in a sub-window associated with the target sleep window, and performing a perception operation in a window other than the sub-window in the target sleep window.

[0208] The third type of information: information indicating available sidelink resources.

[0209] Among them, the available sidelink resources may include time domain resources and / or frequency domain resources for transmitting data. The available sidelink resources refer to the sidelink resources required for data transmission when in a dormant state within a target dormant window. That is, through the indication information of the available sidelink resources, the terminal that receives the indication information of the available sidelink resources can be configured to be in a dormant state within the target dormant window, and to perform data transmission based on the available sidelink resources indicated by the indication information of the available sidelink resources.

[0210] It should be noted that the time domain position of the available sidelink resources is generally after the time domain position of the target sleep window, so that the terminal can perform data transmission based on the available sidelink resources after the target sleep window ends. For example, the time domain position of the available sidelink resources is a period of time T after the time domain end position of the target sleep window, T≥0.

[0211] As an example, the indication information of available sidelink resources is used to indicate the available sidelink resources. In addition, the action of the terminal that has received the indication information of available sidelink resources can be configured through other configuration information, standard provisions or advance negotiation, that is, the terminal that has received the indication information of available sidelink resources is configured to be in a sleep state within a target sleep window, and perform data transmission based on the available sidelink resources indicated by the indication information of available sidelink resources.

[0212] As another example, the indication information of available sidelink resources is not only used to indicate the available sidelink resources, but also can be used to indicate the action of the terminal that has received the indication information of available sidelink resources, that is, it can also be used to indicate being in a sleep state within a target sleep window and performing data transmission based on the available sidelink resources indicated by the indication information of available sidelink resources.

[0213] In the case where the sleep window conflicts with the perception window, the perception operation may not be successfully performed in the perception window where the conflict occurs, and the available sidelink resources required for subsequent data transmission cannot be determined, resulting in the data service not being able to proceed smoothly. In order to solve this problem, the embodiment of the present application can reserve available sidelink resources for the terminal by configuring the first configuration information for the terminal, so that when the terminal cannot perform the perception operation in the target sleep window, it still has available sidelink resources for data transmission, thereby ensuring the smooth progress of the data service.

[0214] Step 702: The communication device sends first configuration information.

[0215] As an example, the communication device sending the first configuration information may include the following implementations:

[0216] The first implementation method: before sending the DRX configuration information or the perception window configuration information, send the first configuration information.

[0217] As an example, before sending DRX configuration information or perception window configuration information, the first configuration information may be sent through RRC, a media access control (MAC) control element (CE) or sidelink control information (SCI).

[0218] That is, in the first implementation, the first configuration information may be configured separately before configuring the sleep window or the perception window, thereby avoiding changes to the sleep window or the perception window configuration process and increasing reliability.

[0219] The second implementation method: sending second configuration information, where the second configuration information includes the first configuration information and one or more of the following information: DRX configuration information, or perception window configuration information.

[0220] As an example, the first configuration information may be carried in the DRX configuration information and sent, or the first configuration information may be carried in the perception window configuration information and sent, or the second configuration information carrying the first configuration information, the DRX configuration information and the perception window configuration information may be sent.

[0221] That is, in the second implementation, the first configuration information may be sent via DRX configuration information and / or perception window configuration information, thereby reducing signaling overhead.

[0222] The third implementation method: before sending the DRX configuration information or the perception window configuration information, send the first sub-information; send the third configuration information, the third configuration information includes the second sub-information and one or more of the following information: DRX configuration information, or perception window configuration information.

[0223] The first sub-information is a part of the first configuration information, and the second sub-information is another part of the first configuration information.

[0224] That is, a part of the first configuration information is sent separately outside the DRX configuration information or the perception window configuration information, and another part of the first configuration information is sent through the DRX configuration information or the perception window configuration information. In this way, the flexibility of information configuration can be increased.

[0225] It should be noted that the communication device can send the first configuration information to the terminal in a directed manner, such as sending the first configuration information to the terminal through unicast or multicast, or can send the first configuration information non-directionally through broadcasting, etc. The embodiment of the present application does not limit the sending method of the first configuration information.

[0226] Step 703: The terminal receives first configuration information.

[0227] The terminal may receive the first configuration information sent by the communication device, for example, by receiving the first configuration information broadcast by the communication device through an antenna.

[0228] As an example, the communication device receiving the first configuration information may include the following implementations:

[0229] The first implementation method: before receiving the DRX configuration information or the perception window configuration information, receiving the first configuration information.

[0230] That is, in addition to the DRX configuration and the perception window configuration, the first configuration information that is configured separately is received.

[0231] A second implementation method: receiving second configuration information, where the second configuration information includes the first configuration information and one or more of the following information: DRX configuration information, or perception window configuration information.

[0232] That is, the second configuration information may be received, and the first configuration information may be acquired from the second configuration information.

[0233] The third method: before receiving the DRX configuration information or the perception window configuration information, receive the first sub-information; receive the third configuration information, the third configuration information including the second sub-information and one or more of the following information: DRX configuration information, or perception window configuration information.

[0234] The first sub-information is a part of the first configuration information, and the second sub-information is another part of the first configuration information.

[0235] That is, a part of the information in the first configuration information is received separately, and another part of the information in the first configuration is received through the DRX configuration information or the perception window configuration information.

[0236] Step 704: Based on the first configuration information, a conflict resolution strategy is executed in a target sleep window, where the target sleep window refers to all or part of the sleep windows of the terminal that conflict with the perception window of the terminal.

[0237] The sleep window of the terminal may include multiple target sleep windows, and a conflict resolution strategy may be executed in each target sleep window to avoid conflicts between the sensing operation and the sleep state.

[0238] As an example, based on the first configuration information, executing the conflict resolution strategy in the target sleep window may include the following implementations:

[0239] The first implementation method: when the first configuration information includes perception operation indication information, the perception operation is performed in the target sleep window based on the first configuration information.

[0240] That is, the sensing operation is performed within the target sleep window without being in the sleep state, thereby avoiding the conflict between the sensing operation within the target sleep window and being in the sleep state.

[0241] Please refer to Figure 8 , Figure 8 is a schematic diagram of executing a conflict resolution strategy based on perception indication information provided by an embodiment of the present application, Figure 8 The solid-line frame in the figure is the sensing window, the dotted-line frame is the sleep window, the cross-hatched frame is the target sleep window for the sensing operation, and the diagonal-line frame is the available sidelink resource. Figure 8 As shown in Figure (a), in the prior art, when a sleep window conflicts with a perception window, the terminal does not know whether to perform a perception operation or switch to an idle state in the conflicting part of the window, which may cause the terminal to be unable to perform the perception operation normally, and further unable to perceive the available sidelink resources required for subsequent data transmission, resulting in the inability to carry out data services smoothly.

[0242] In the present application embodiment, Figure 8 Figure (b) and Figure 8 As shown in FIG. (c), after receiving the first configuration information including the sensing operation indication information, the terminal can perform the sensing operation in the target sleep window when the sleep window conflicts with the sensing window. By performing the sensing operation in the target sleep window, the available sidelink resources required for the data can be sensed. Figure 8 In Figure (b), the target sleep window refers to the sleep window that conflicts with the perception window. Figure 8 In Figure (c), the target sleep window refers to the part of the sleep window that conflicts with the perception window.

[0243] By sending perception operation indication information, the terminal can be instructed to perform perception operations in the sleep window that conflicts with the perception window when a conflict occurs between the sleep window and the perception window, without putting the device in a sleep state. This avoids the conflict between the perception operation in the target sleep window and the sleep state, and reduces the power consumption of the device while ensuring the smooth progress of data services.

[0244] The second implementation method: If the first configuration information includes indication information of a sub-window, a perception operation is performed in a sub-window of the target sleep window, and the window other than the sub-window in the target sleep window is in a sleep state; or, the window other than the sub-window in the target sleep window is in a sleep state, and a perception operation is performed in a window other than the sub-window in the target sleep window.

[0245] For the second implementation, in the following Fig.10 The details are described in the embodiments and will not be repeated here.

[0246] A third implementation manner: if the first configuration information includes indication information of available sidelink resources, the device is in a sleep state within a target sleep window, and after the sleep state ends, data transmission is performed based on the available sidelink resources.

[0247] Please refer to Fig. 9 , Fig. 9 This is a schematic diagram of another conflict resolution strategy based on available sidelink resources provided in an embodiment of the present application. Fig. 9 The solid-line frame is the sensing window, the dotted-line frame is the sleep window, the vertical-line frame is the target sleep window in the sleep state, and the diagonal-line frame is the available sidelink resource. Fig. 9 As shown in Figure (a), in the prior art, when a sleep window conflicts with a sensing window, the terminal does not know whether to perform a sensing operation or switch to an idle state in the conflicting window, which may cause the terminal to fail to perform a sensing operation normally, and thus fail to sense the available sidelink resources required for subsequent data transmission, resulting in data services not being able to proceed smoothly. Fig. 9 As shown in Figure (b), in an embodiment of the present application, after receiving the first configuration information including indication information of available sidelink resources, the terminal can be in a sleep state within the target sleep window when a sleep window conflicts with the perception window, without performing a perception operation, and after the sleep state ends, data transmission is performed on the configured available sidelink resources.

[0248] It should be noted that if the indication information of available sidelink resources is configured for the terminal, then in the multicast or broadcast scenario, it is also necessary to configure available sidelink resources that can be distinguished from each other for each device in the group, that is, to configure different available sidelink resources for each device in the group. As an example, when configuring available sidelink resources for each device in the group, the available sidelink resources of each device in the group can be associated with the device identification of each device in the group.

[0249] As an example, if the communication device is a terminal, before the communication device sends the indication information of the available sidelink resources to the terminal, the communication device may also perform an auxiliary sensing operation for the terminal to determine the available sidelink resources of the terminal through the auxiliary sensing operation, and configure the determined available sidelink resources to the terminal through the first configuration information. In this way, when the sleep window conflicts with the perception window, the terminal can be in a sleep state in the target sleep window that conflicts with the perception window based on the indication information of the available sidelink resources, and then perform data transmission based on the available sidelink resources configured by the first terminal.

[0250] That is, in a scenario where the first terminal configures information for the second terminal, the available sidelink resources configured by the first terminal for the second terminal can be determined by the first terminal performing an auxiliary sensing operation. In addition, the second terminal can also reserve receiving resources to receive the first configuration information sent by the first terminal through the reserved receiving resources.

[0251] In the third implementation method, available sidelink resources can be reserved for the terminal by sending indication information of available sidelink resources. In this way, even if the terminal is in a sleep state in a target sleep window that conflicts with the perception window and does not perform a perception operation, data transmission can be performed based on the reserved available sidelink resources, thereby avoiding the conflict between the perception operation in the target sleep window and the sleep state, reducing the power consumption overhead of the equipment while ensuring the smooth operation of data services.

[0252] It should be noted that the embodiments of the present application can be applicable to scenarios such as unicast, multicast or broadcast.

[0253] In an embodiment of the present application, by sending the first configuration information, a conflict resolution strategy can be configured for the terminal when a conflict occurs between the sleep window and the perception window, so that the terminal executes the corresponding conflict resolution strategy when a conflict occurs between the sleep window and the perception window, thereby solving the problem that the terminal does not know whether to perform a perception operation or remain in a sleep state when a conflict occurs between the sleep window and the perception window, thereby reducing the power consumption overhead of the device while ensuring the smooth progress of data services.

[0254] Next, taking the case where the first configuration information includes indication information of a sub-window as an example, the information configuration method provided in the embodiment of the present application is exemplarily described.

[0255] Fig.10 is a flowchart of another information configuration method provided by an embodiment of the present application, wherein the interaction subjects of the method are a communication device and a terminal, such as Fig.10 As shown, the method comprises the following steps:

[0256] Step 1001: A communication device generates first configuration information, where the first configuration information includes indication information of a sub-window, where the sub-window is a window in a target dormant window.

[0257] It should be noted that the target sleep window refers to part or all of the sleep windows that conflict with the perception window. The sub-window is a window associated with the target sleep window, specifically a window associated with part or all of the windows of the target sleep window. For example, the sub-window is part or all of the windows in the target sleep window, or is a window that overlaps part or all of the windows in the target sleep window.

[0258] The indication information of the sub-window is used to indicate the sub-window. The indication information of the sub-window may be the resource location information of the sub-window, which is used to characterize the time resource where the sub-window is located. Alternatively, the indication information of the sub-window is the location information of the sub-window in the target sleep window, which is used to characterize the location of the sub-window in the target sleep window. The indication information of the sub-window may include the indication information of the time domain and / or frequency domain of the sub-window.

[0259] In addition, the indication information of the sub-window can also be used to indicate that the sensing operation is performed in a part of the target sleep window, and the other part of the target sleep window is in a sleep state. In this way, the device receiving the indication information of the sub-window can perform the sensing operation in a part of the target sleep window and be in a sleep state in another part of the window, thereby avoiding the conflict between the sensing operation in the target sleep window and being in a sleep state.

[0260] For example, the indication information of the sub-window is used to indicate that the sensing operation is performed in the sub-window associated with the target sleep window, and the windows other than the sub-window in the target sleep window are in a sleep state. Alternatively, the indication information of the sub-window is used to indicate that the sub-window associated with the target sleep window is in a sleep state, and the sensing operation is performed in the windows other than the sub-window in the target sleep window.

[0261] As an example, the indication information of the sub-window includes one or more of the following information:

[0262] 1) Window size information of the sub-window, the starting position of the sub-window is the starting position of the target dormant window, or the ending position of the sub-window is the ending position of the target dormant window.

[0263] In the first type of information, the sub-window is a front portion of the window or a back portion of the window in the target dormant window.

[0264] The window size information of the sub-window is used to indicate the window size of the sub-window. The window size of the sub-window may include the size of the sub-window in the time domain and / or the size of the sub-window in the frequency domain.

[0265] As an example, the window size information of the sub-window may include a duration T, which is used to indicate that a duration T starting from the start time of the target sleep window is used as the sub-window, or a duration T ending from the end time of the target sleep window is used as the sub-window, where T≥0.

[0266] It should be noted that whether to use the starting position of the target sleep window as the starting position of the sub-window, or to use the ending position of the target sleep window as the ending position of the sub-window, can be determined by standard regulations or negotiated in advance by the communication device and the terminal, or can be configured through configuration information, and the embodiments of the present application do not limit this.

[0267] As an example, the indication information of the sub-window may include first indication information or second indication information in addition to the window size information of the sub-window. The first indication information is used to indicate the starting position of the sub-window, and the starting position of the sub-window is the starting position of the target dormant window. The second indication information is used to indicate the end position of the sub-window, and the end position of the sub-window is the end position of the target dormant window.

[0268] 2) The starting position information and ending position information of the subwindow.

[0269] In the second information, the sub-window is a part of the window or the whole window in the target sleep window, and may be a window in the front part or the back part of the target sleep window, or a window in the middle part of the target sleep window.

[0270] The starting position information and the ending position information of the sub-window are used to determine the time resource where the sub-window is located. As an example, the starting position information and the ending position information of the sub-window may include time domain position information and / or frequency domain position information. For example, if the target sleep window is a full frequency domain window, the starting position information and the ending position information of the sub-window may include the starting position information and the ending position information in the time domain.

[0271] As another example, the starting position information and the ending position information of the sub-window may also be the starting position information and the ending position information of the sub-window in the target dormant window. For example, the starting position information of the sub-window may be the relative position information or distance information between the starting position of the sub-window and the starting position of the target dormant window, and the ending position information of the sub-window may be the relative position information or distance information between the ending position of the sub-window and the ending position of the target dormant window.

[0272] 3) The starting position information of the first window among the multiple windows spaced apart from each other included in the sub-window, the ending position information of the last window among the multiple windows, and the spacing rule of the multiple windows.

[0273] In the third information, the sub-windows are multiple windows spaced apart from each other in the target dormant window. The indication information of the sub-windows includes the starting position information of the first window among the multiple windows, the ending position information of the last window, and the spacing rule of the multiple windows.

[0274] It should be noted that the starting position information of the first window and the ending position information of the last window may include time domain position information and / or frequency domain position. For example, if the target sleep window is a full frequency domain window, the starting position information of the first window is the starting position information in the time domain, and the ending position information of the last window is the ending position information in the time domain.

[0275] Alternatively, the starting position information of the first window may be the starting position information in the target sleep window, and the ending position information of the last window may be the ending position information in the target sleep window. For example, the starting position information of the first window may be the relative position information or distance information between the starting position of the first window and the starting position of the target sleep window, and the ending position information of the last window may be the relative position information or distance information between the ending position of the last window and the ending position of the target sleep window.

[0276] In addition, the spacing rule of multiple windows is used to indicate how the multiple windows are spaced. For example, the spacing rule of multiple windows may include the window size information of each window in the multiple windows, and the window size information of the intervals between the windows. For another example, the spacing rule of multiple windows may be the window indication information of each resource unit included in the target window. Among them, the target window refers to the window between the starting position of the first window and the ending position of the last window. The target window includes multiple resource units, and the resource units may include time domain units and / or frequency domain units. For example, the resource unit may be a subframe or time slot in the time domain. The window indication information of the resource unit is used to indicate whether the resource unit belongs to a subwindow. For example, if the window indication information of a resource unit is 1, it means that the resource unit belongs to the subwindow; if the window indication information of a resource unit is 0, it means that the resource unit does not belong to the subwindow.

[0277] Please refer to Table 1, which is an exemplary description of an interval rule for multiple windows provided in an embodiment of the present application. As shown in Table 1, assuming that the target window includes 10 time slots in the time domain, the interval rule for multiple windows may include window indication information for each of the 10 time slots. For these 10 time slots, if the window indication information of a time slot is 1, it means that the time slot belongs to a sub-window, and if the window indication information of a time slot is 0, it means that the time slot does not belong to a sub-window. As shown in Table 1, time slots 1 and 2 belong to sub-windows, time slots 3 and 4 do not belong to sub-windows, time slots 5 and 6 belong to sub-windows, time slots 7 and 8 do not belong to sub-windows, and time slots 9 and 10 belong to sub-windows. In this way, the 10 time slots can be divided into 3 windows spaced apart from each other.

[0278] Table 1

[0279]

[0280] As an example, the first configuration information may include first window indication information or second window indication information in addition to the indication information of the sub-window.

[0281] The first window indication information is used to indicate that the subwindow is a sensing subwindow, and the sensing subwindow refers to a subwindow that needs to perform a sensing operation. Accordingly, the subwindow indication information is used to indicate that the sensing operation is performed in the subwindow associated with the target sleep window, and that the windows other than the subwindow in the target sleep window are in a sleep state.

[0282] The second window indication information is used to indicate that the sub-window is a dormant sub-window, and the dormant sub-window refers to a sub-window that needs to be in a dormant state. Accordingly, the sub-window indication information is used to indicate that the sub-window associated with the target dormant window is in a dormant state and to perform a sensing operation in windows other than the sub-window in the target dormant window.

[0283] In a possible implementation, the first window indication information and the second window indication information may also be sent separately outside the indication information of the sub-window. For example, the first configuration information is sent through DRX configuration information, and the first configuration information includes the indication information of the sub-window. Before sending the first configuration information through DRX configuration information, the first window indication information or the second window indication information is sent through RRC, MAC CE or SCI.

[0284] Step 1002: The communication device sends first configuration information to the terminal.

[0285] That is, the communication device may send the first configuration information to the terminal based on the DRX configuration information.

[0286] Step 1003: The terminal receives first configuration information.

[0287] Step 1004: The terminal determines a sub-window from the target sleep window based on the sub-window indication information included in the first configuration information.

[0288] The operation of determining the sub-window from the target dormant window based on the indication information of the sub-window may include the following implementation methods:

[0289] The first implementation method: if the indication information of the sub-window includes window size information, based on the window size information, the sub-window is determined from the target sleep window with the start position of the target sleep window as the start position or the end position of the target sleep window as the end position.

[0290] In the first implementation, the child window is a portion of the window at the front or the portion of the window at the back of the target dormant window. Figure 11-Figure 16 , Figure 11-Figure 16 Schematic diagram of several sub-window-based indication information conflict resolution strategies provided in the embodiments of the present application. Fig.11 As shown, Fig.11 The child window in is the part of the window behind the target dormant window. Fig.14 As shown, Fig.14 The sub-window in is the front part of the target dormant window.

[0291] The second implementation manner: if the indication information of the sub-window includes the starting position information and the ending position information, the sub-window is determined from the target dormant window based on the starting position information and the ending position information.

[0292] In the second implementation, the child window can be a partial window near the front or a partial window near the back of the target sleep window, or a partial window in the middle of the target sleep window. Fig.12 and Fig.15 , Fig.12 and Fig.15 The sub-window in is the middle part of the target dormant window.

[0293] A third implementation method: If the indication information of the sub-window includes the starting position information of the first window among multiple windows spaced from each other, the ending position information of the last window, and the spacing rule of the multiple windows, then based on the starting position information of the first window, the ending position information of the last window, and the spacing rule of the multiple windows, multiple windows are determined from the target dormant window, and the multiple windows are used as sub-windows.

[0294] As an example, if the spacing rule of multiple windows is the window indication information of each resource unit in the multiple resource units included in the target window, the target window refers to the window between the starting position of the first window and the ending position of the last window, and the window indication information of each resource unit is used to indicate whether each resource unit belongs to a subwindow, then multiple windows can be determined from the target window based on the window indication information of each resource unit in the multiple resource units included in the target window. The target window can be determined based on the starting position information of the first window and the ending position information of the last window.

[0295] In a third implementation, the sub-window includes multiple windows that are spaced apart from each other. Fig.13 and Fig.16 , Fig.13 and Fig.16 The sub-windows in the target dormant window are multiple windows that are spaced apart from each other in the target dormant window.

[0296] Step 1005: The terminal performs a sensing operation in a subwindow of the target sleep window and is in a sleep state in a window other than the subwindow in the target sleep window, or is in a sleep state in a subwindow of the target sleep window and performs a sensing operation in a window other than the subwindow in the target sleep window.

[0297] It should be noted that the terminal can determine whether the sub-window is a perception sub-window or a sleep sub-window based on standard regulations, rules negotiated in advance with the communication device, or relevant information carried by the first configuration information, and then determine whether to perform a perception operation in a sub-window of the target sleep window and be in a sleep state in a window other than the sub-window, or to be in a sleep state in a sub-window of the target sleep window and perform a perception operation in a window other than the sub-window.

[0298] For example, if the first configuration information also includes first window indication information, the terminal can perform a sensing operation in a sub-window determined from the target sleep window based on the indication information of the sub-window, and be in a sleep state in a window other than the sub-window in the target sleep window. If the first configuration information also includes second window indication information, the terminal can be in a sleep state in a sub-window determined from the target sleep window based on the indication information of the sub-window, and perform a sensing operation in a window other than the sub-window in the target sleep window.

[0299] Please refer to Fig.11 , Fig.12 and Fig.13 , Figure 11-13 It is a schematic diagram of three conflict resolution strategies based on the indication information of the perception sub-window provided in the embodiments of the present application. Figure 11-13 The solid-line frame in the figure is the perception window, the dotted-line frame is the sleep window, the black-dot frame is the perception sub-window used to perform the perception operation, and the diagonal-line frame is the available sidelink resource. Fig.11 Figure (a) in Fig.12 Figure (a) and Fig.13 As shown in (a) of FIG. 1 , in the prior art, when a sleep window conflicts with a sensing window, the terminal does not know whether to perform a sensing operation or switch to an idle state in the conflicting part of the window, which may cause the terminal to be unable to perform a sensing operation normally, and thus unable to sense the available sidelink resources required for subsequent data transmission, resulting in data services being unable to proceed smoothly. In the embodiment of the present application, Fig.11 Figure (b) in Fig.12 Figure (b) and Fig.13 As shown in (b) of FIG. 1 , after receiving the first configuration information including the indication information of the sub-window, the terminal can, when the sleep window conflicts with the perception window, perform the perception operation in the perception sub-window in the target sleep window and be in the sleep state in the window other than the perception sub-window in the target sleep window. The target sleep window refers to the sleep window that conflicts with the perception window.

[0300] Please refer to Fig.14 , Fig.15 and Fig.16 , Figure 14-16 It is a schematic diagram of three conflict resolution strategies based on the indication information of the dormant sub-window provided in the embodiments of the present application. Figure 14-16 The solid-line frame in the figure is the sensing window, the dotted-line frame is the dormant window, the black frame is the dormant child window in dormant state, and the diagonal-line frame is the available sidelink resource. Fig.14 Figure (a) in Fig.15 Figure (a) and Fig.16As shown in (a) of FIG. 1 , in the prior art, when a sleep window conflicts with a sensing window, the terminal does not know whether to perform a sensing operation or switch to an idle state in the conflicting part of the window, which may cause the terminal to be unable to perform a sensing operation normally, and thus unable to sense the available sidelink resources required for subsequent data transmission, resulting in data services being unable to proceed smoothly. In the embodiment of the present application, Fig.14 Figure (b) in Fig.15 Figure (b) and Fig.16 As shown in (b) of FIG. 1 , after receiving the first configuration information including the indication information of the sub-window, the terminal can be in a dormant state in the dormant sub-window in the target dormant window and perform a perception operation in the window other than the dormant sub-window in the target dormant window when the dormant window conflicts with the perception window. The target dormant window refers to the dormant window that conflicts with the perception window.

[0301] It should be noted that Figure 11-Figure 16 The target sleep window is taken as an example to refer to the sleep window that conflicts with the perception window. In other cases, the target sleep window may also be a part of the sleep window that conflicts with the perception window.

[0302] In an embodiment of the present application, by sending indication information of a sub-window, the terminal can be instructed to perform a perception operation in a part of the target sleep window that conflicts with the perception window, and to be in a sleep state in another part of the target sleep window when a conflict occurs between the sleep window and the perception window, thereby avoiding the conflict between the perception operation in the target sleep window and the sleep state, reducing the power consumption overhead of the device while ensuring the smooth progress of data services.
