Description

Technical Field

[0001] The present disclosure relates to the field of communications, and in particular to a method and apparatus for determining and indicating resource configuration. Background Art

[0002] With the development of wireless communication technology and the increasing demand of users for communication, in order to meet higher, faster and newer communication needs, the fifth generation mobile communication (5G, 5th Generation) technology has become the trend of future network development.

[0003] In a sidelink (also known as a direct link) communication system, when there is a service transmission between user equipments (UEs), the service data between the UEs does not pass through the network side, that is, it does not pass through the cellular link between the UE and the base station. Instead, it is directly transmitted from the data source UE to the target UE through the sidelink. Figure 1 is a schematic diagram of the Sidelink communication structure in the related art, such as Figure 1 As shown, this mode of direct communication between UEs has characteristics that are significantly different from the traditional cellular system communication mode. For short-range communication users that can use Sidelink communication, Sidelink communication not only saves wireless spectrum resources, but also reduces the data transmission pressure of the core network, can reduce system resource usage, increase the spectrum efficiency of the cellular communication system, reduce terminal transmission power consumption, and greatly save network operating costs.

[0004] In 5G communication systems, the minimum granularity of time domain resources is a symbol, which can be divided into: Cyclic Prefix-OFDM Orthogonal Frequency Division Multiplexing (CP-OFDM) or Discrete Fourier Transform Spread OFDM (DFT-S-OFDM).

[0005] Furthermore, a time slot includes 12 consecutive symbols of an extended cyclic prefix (extend CP) or 14 consecutive symbols of a normal cyclic prefix (normal CP). Figure 2 This is a schematic diagram showing the time slot in the 5G system in the related art. Figure 2As shown. Alternatively, a mini-slot can be composed of one or more consecutive symbols (less than or equal to 7 symbols). In the frequency domain, the minimum granularity of resources is a sub-carrier. Depending on the system configuration, the frequency domain width contained in each sub-carrier is different, including any one or more of the following: 15kHz, 30kHz, 60kHz, 120kHz, 240kHz. A frequency domain resource block (RB) can be formed by 12 consecutive sub-carriers. As mentioned above, the symbol or time slot or mini-slot is the resource unit of the time domain resource configuration in the 5G system, and the RB is the resource unit of the frequency domain resource configuration. When implementing Sidelink communication in the 5G communication system, the same time domain and frequency domain resource units should also be used as the basis to implement the configuration of Sidelink resources.

[0006] In a 5G system, the base station indicates the time and frequency domain resource configuration for cellular communication to cellular link users. This includes the symbol and slot division in the time domain, as well as the type of each symbol; the frequency domain includes the division of subcarriers and RBs. In the time domain, there are three symbol types: downlink symbols (DL symbols), uplink symbols (UL symbols), and flexible symbols (F symbols). Each symbol in each slot can be configured as any of these three symbol types. Figure 3 Schematic diagram of an example of symbol type configuration in a time slot in a 5G system in the related art. Figure 3 In the example shown, Example #1 contains 5 DL symbols (such as Figure 3 ), 5 UL symbols (such as Figure 3 ), and 4 Flexible symbols (such as Figure 3 (as shown by the blank squares in the figure). Among them, the DL symbol is used to carry downlink signals, that is, signals sent from the base station to the UE; the UL symbol is used to carry uplink signals, that is, signals sent from the UE to the base station; the Flexible symbol is a flexibly reconfigurable symbol, that is, the F symbol can be further reconfigured as a DL symbol or a UL symbol. In addition, the symbol type that has been configured as a DL symbol or a UL symbol cannot be changed. The symbol type and position in each slot are indicated by the system through signaling configuration. Other examples of symbol configuration in a slot are Figure 3 As shown in , I will not repeat it here.

[0007] When implementing sidelink communication in a 5G communication system, sidelink and cellular communication share resources, while ensuring that their resource allocation does not conflict. Because 5G cellular communication utilizes flexible resource allocation schemes and scheduling instructions, there is currently no solution for coordinating the allocation of cellular and sidelink communication resources in a 5G system. This disclosure proposes a solution to this problem. Summary of the Invention

[0008] The embodiments of the present disclosure provide a method and apparatus for determining and indicating resource configuration, so as to at least solve the problem in the related art that coordinated configuration of cellular communication resources and sidelink communication resources cannot be achieved in a 5G system.

[0009] According to an embodiment of the present disclosure, a method for determining resource configuration is provided, including: a first node obtains first configuration information and second configuration information, wherein the first configuration information is used to indicate the usage status of flexible resources in an edge link, and the second configuration information is used to indicate a first time domain resource in an edge link resource pool; based on the first configuration information and the second configuration information, the first node determines the second time domain resource in the edge link resource pool, wherein the second time domain resource is the first time domain resource or a subset of the first time domain resource.

[0038] The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0040] It should be noted that in a sidelink communication system, sidelink resources are used between UEs to transmit information. Depending on the specific application scenario and service type, sidelink communication methods include but are not limited to: device-to-device (D2D) communication, vehicle-to-vehicle (V2V) communication, etc. In the sidelink communication of related technologies, the UE uses resources in the sidelink resource pool to send sidelink signals. The sidelink resource pool includes:

[0041] The physical sidelink control channel (PSCCH) resource pool is used to carry sidelink control information; the physical sidelink shared channel (PSSCH) resource pool is used to carry sidelink data service information; the physical sidelink broadcast channel (PSBCH) resource pool is used to carry sidelink broadcast information; the physical sidelink discovery channel (PSDCH) resource pool is used to carry sidelink discovery signals; and the physical sidelink feedback channel (PSFCH) resource pool is used to carry sidelink feedback information.

[0042] Alternatively, a sidelink resource pool can be defined as a resource set that includes any one or more of the aforementioned sidelink channel resources. For example, a sidelink resource pool includes PSCCH, PSSCH, and PSFCH resources, rather than being referred to as a PSCCH resource pool, PSSCH resource pool, or PSFCH resource pool. It should be noted that both methods are ways of defining sidelink resources and do not affect the essence of the disclosed solution.

[0043] Typically, based on specific scenario requirements, the network configures a sidelink resource pool for a sidelink UE, or the system preconfigures a sidelink resource pool. The UE then uses resources in the sidelink resource pool to carry sidelink information. In network-side configuration or system-predefined configuration, any one or more of the aforementioned types of sidelink resource pools can be configured for a sidelink UE. The system can be a wireless communication network system, which can be considered to be determined by a higher-level node. The sidelink resource pool is a collection of predefined resources.

[0044] When a UE exchanges information on the sidelink, the transmitting UE sends Sidelink Control Information (SCI) on the PSCCH resource to indicate to the receiving UE the PSSCH resource used for the transmitted sidelink data information, as well as related control information such as the modulation and coding scheme (MCS), power control indication, and data retransmission indication. Furthermore, the transmitting UE sends sidelink data on the PSSCH resource indicated by the SCI. In addition, the UE can also send sidelink broadcast information on the PSBCH resource, send sidelink discovery information on the PSDCH resource, and provide feedback to the transmitting end on the PSFCH resource regarding the acknowledgment / non-acknowledgment (Ack / Nack) of received data packets.

[0045] The network side includes but is not limited to base stations (gNBs), relay stations (RNs), cell coordination entities (MCEs), gateways (GWs), mobility management equipment (MMEs), and Evolved Universal Terrestrial Radio Access Network (EUTRAN) operations, management, and maintenance (OAM) managers.

[0046] Optionally, the Sidelink resource pool is a group of resources used to carry Sidelink information or signals, which is configured by the network side through physical layer and / or high-layer signaling, or pre-configured by the system. Each Sidelink resource pool can contain one or more time domain resource units in the time domain, and the time domain resource unit includes any one or more of the following: symbol, slot, mini-slot; and contains one or more RBs in the frequency domain, and the multiple RBs contained can be continuous or discontinuous. Among them, the PSCCH resource pool, PSSCH resource pool, PSBCH resource pool, and PSDCH resource pool are all types of Sidelink resource pools. The configuration indication method for the Sidelink resource pool in this application can be applied to any one or more of the above resource pool configurations.

[0047] When sidelink resource pools share cellular communication time and frequency domain resources, they must be configured based on the existing time and frequency domain resources in the cellular link. For example, time domain resources in the sidelink resource pool can be further configured based on the symbol and slot divisions and symbol types indicated by the cellular link.

[0048] Because UEs can maintain both cellular and sidelink communications simultaneously, the configuration of the sidelink resource pool needs to minimize conflicts with cellular communication resources. In other words, the time and frequency domain resources contained in the sidelink resource pool should minimize impact on the resource configuration of the cellular link. In next-generation communication systems such as 5G systems, UEs performing cellular communications within a cell can determine the symbol type of each symbol in each slot in the time domain by receiving corresponding configuration signaling from a network-side node (such as a base station). Furthermore, based on the base station's scheduling instructions, the UE uses symbols of the corresponding symbol type to receive or transmit signals.

[0049] It should also be noted that since sidelink communication signals are transmitted by the UE and received by other nearby UEs supporting sidelink communication, to avoid interference from cellular downlink signals, UL symbols and / or F symbols should be used in the sidelink resource pool, rather than DL symbols. The UL symbols or F symbols referred to herein refer to UL symbols or F symbols configured by the base station for the cellular link in cellular communication. When all symbols in a slot are configured as F symbols, it is also referred to as an F slot. For simplicity, these symbols are collectively referred to as F resources in the following description. F resources refer to time-domain symbols configured as F symbols, or F slots. Furthermore, F resources are time-domain resources indicated as F symbols or F slots by the base station in the resource configuration for cellular communication (i.e., on the Uu interface between the base station and the UE). They can be F resources configured and indicated by the base station via a cell broadcast message, or F resources indicated in dedicated configuration information sent by the base station to the UE. The dedicated configuration information includes a UE-specific RRC message or a DCI indication.

[0050] Because F resources in the NR system can be further configured as DL resources or UL resources, they are highly flexible, allowing the same slot or symbol to have different configurations for different UEs. For example, slot #n contains several F symbols, which can be reconfigured as DL symbols for UE A and as UL symbols for UE B. However, when F resources are configured as DL resources, they cannot be used as sidelink resources. If the configuration is not properly coordinated, this may cause a conflict between the cellular communication configuration and the sidelink resource configuration. The solution proposed in this disclosure solves the problem of further configuring F resources configured for cellular communication in the NR system as sidelink resources, thereby avoiding resource configuration conflicts, improving resource utilization, and effectively realizing the sharing of cellular and sidelink communication resources.

[0051] Example 1

[0052] In this embodiment, a method for determining resource configuration is provided. Figure 4 is a flow chart of a method for determining resource configuration according to an embodiment of the present disclosure, such as Figure 4 As shown, the process includes the following steps:

[0053] Step S402: The first node obtains first configuration information and second configuration information, wherein the first configuration information is used to indicate the usage status of the flexible resource in the edge link, and the second configuration information is used to indicate the first time domain resource in the edge link resource pool;

[0054] Step S404: Based on the first configuration information and the second configuration information, the first node determines the second time domain resources in the edge link resource pool, wherein the second time domain resources are the first time domain resources or a subset of the first time domain resources.

[0055] It should be noted that the first node in the present disclosure includes but is not limited to: PC terminals, mobile terminals and other terminal devices. The second node in the present disclosure includes but is not limited to: base stations, network elements and other network side devices.

[0056] Among them, the first time domain resources of the side link resource pool or the second time domain resources of the side link resource pool refer to a set including one or more time domain resource units. The second configuration information indicates the first time domain resources of the side link resource pool. The first time domain resources may include time domain resources of any one or more resource types. The types of time domain resources include downlink resources, uplink resources, and flexible resources. According to the configuration indication of the first configuration information, the first node can further exclude the side link resources configured as unavailable in the first time domain resources of the side link resource pool, and determine the time domain resources that can actually be used for side link communication, that is, the second time domain resources in the side link resource pool. Therefore, the second time domain resources of the side link resource pool are the full set or subset of the first time domain resources.

[0057] Optionally, the first node obtains the first configuration information and the second configuration information through at least one of the following methods: the system predefines the first configuration information and / or the second configuration information; the system preconfigures the first configuration information and / or the second configuration information; the first node receives configuration indication signaling from the second node, wherein the configuration indication signaling is used to indicate the first configuration information and / or the second configuration information.

[0058] Optionally, the method also includes: the first node determines the configuration information of the time domain resource type according to the system pre-configuration or the configuration indication of the second node; wherein, the configuration information of the time domain source type is used to indicate the time domain resource type of each time domain resource unit, and the time domain resource type includes at least one of the following: downlink resources, the flexible resources, uplink resources, and the time domain resource unit includes at least one of the following: time slot, symbol.

[0059] Optionally, the first configuration information is used to indicate the usage status of the flexible resource in the side link, and is characterized in that: the first configuration information is used to indicate that the flexible resource is available for the side link, or that the flexible resource is unavailable for the side link. Indicating that the flexible resource is available for the side link is also called enabling the side link, which means that the flexible resource can be used for Sidelink communication and can be used as a resource in the Sidelink resource pool; correspondingly, indicating that the flexible resource is unavailable for the side link is also called disabling the side link, which means that the flexible resource cannot be used for Sidelink communication and cannot be used as a resource in the Sidelink resource pool.

[0060] Optionally, the flexible resources include the time slots and / or the symbols configured as the flexible resource type; the flexible resources include at least one of the following: flexible resources indicated in the cell public configuration, and flexible resources indicated in the first node dedicated configuration.

[0061] Optionally, based on the first configuration information and the second configuration information, the first node determines the second time domain resource, including: if the resource type of the first time domain resource is the downlink resource, then the first node determines that the first time domain resource is invalid, that is, the first time domain resource cannot be used for edge link communication and is not included in the second time domain resource of the edge link resource pool.

[0062] Optionally, based on the first configuration information and the second configuration information, the first node determines the second time domain resource, including: if the resource type of the first time domain resource is the uplink resource, then the first node determines that the first time domain resource is valid, that is, the first time domain resource is used for edge link communication and is included in the second time domain resource of the edge link resource pool.

[0063] Optionally, if the time domain resource type is the flexible resource, the first node determines the second time domain resource based on the first configuration information, including: when the first configuration information indicates that the flexible resource is available to the edge link, the first node determines that the first time domain resource is valid; when the first configuration information indicates that the flexible resource is not available to the edge link, the first node determines that the first time domain resource is invalid.

[0064] It should be pointed out that the three time domain types of resources, downlink resources (DL symbol and / or DL ​​slot), flexible resources (F symbol and / or F slot), and uplink resources (UL symbol and / or UL slot), are pre-configured by the system or indicated by the base station configuration, and are cell-level public configuration or UE-specific configuration, or the total collection of resources of cell-level public configuration and UE-specific configuration.

[0065] Optionally, the configuration indication signaling includes at least one of the following: cell common configuration signaling, the UE-specific high-layer signaling, downlink control information signaling (DCI), side link broadcast message, side link control indication (SCI) signaling.

[0066] Specifically, the cell public configuration information includes but is not limited to one or any combination of the following: system information (SI); master information block (MIB); system information block (SIB); other system information (OSI); and remaining system information (RMSI).

[0067] Specifically, the dedicated high-layer signaling may include but is not limited to: dedicated radio resource control (RRC, Radio Resource Control) signaling.

[0068] It should be noted that, provided there is no conflict, the method for carrying the indication information of resources used for sidelink communication can use any one or any combination of the above-mentioned system signaling. The UE can determine the type of signaling to receive based on system pre-defined or network-side configuration and obtain the corresponding resource configuration information for the sidelink resources.

[0069] In addition, it should be noted that multiple resource pools can be configured on the Sidelink at the same time, and the first configuration information and / or the second configuration information can be independently configured for each resource pool.

[0070] In addition, the UE may obtain the first configuration information and / or the second configuration information through pre-configuration. The system pre-configured first configuration information may be set to indicate whether the flexible resource is available or unavailable for Sidelink, and the pre-configured second configuration information may be set to indicate that the Sidelink resource pool includes all time domain resources.

[0071] Optionally, the first configuration information includes at least one of the following types: Type 0 first configuration information, wherein the Type 0 first configuration information is the first configuration information obtained by the first node according to system predefinition or preconfiguration; Type 1 first configuration information, wherein the Type 1 first configuration information is the first configuration information obtained by the first node according to the system broadcast message of the second node; Type 2 first configuration information, wherein the Type 2 first configuration information is the first configuration information obtained by the first node according to the dedicated high-level signaling configuration of the second node; Type 3 first configuration information, wherein the Type 3 first configuration information is the first configuration information obtained by the first node according to the dedicated dynamic signaling configuration of the second node.

[0072] Optionally, the first configuration information is used to indicate at least one of the following: whether the flexible resources in the cell-common configuration are available or unavailable to the side link; whether the flexible resources in the first node-dedicated configuration are available or unavailable to the side link; whether the flexible time slot resources in the flexible resources are available or unavailable to the side link; and whether the flexible symbol resources in the flexible resources are available or unavailable to the side link.

[0073] Optionally, the method further includes: when obtaining multiple types of the first configuration information, the first node determines the usage status of the flexible resource in the edge link according to a predefined priority rule.

[0074] Optionally, the first node obtains the type 0 first configuration information and the type 1 first configuration information, and when the type 0 first configuration information and the type 1 first configuration information have different indications on the same flexible resource, that is, one of the first configuration information indicates that the side link is available, and the other indicates that the side link is unavailable, the first node takes the indication of the type 1 first configuration information as a valid indication, and determines whether the flexible resource is available or unavailable for the side link based on the type 1 first configuration information.

[0075] Optionally, the first node obtains the type 1 first configuration information and the type 2 first configuration information. On the same flexible resource, if the indications of the type 1 first configuration information and the type 2 first configuration information are different, the first node takes the indication of the type 2 first configuration information as a valid indication and determines whether the flexible resource is available or unavailable for the edge link based on the type 2 first configuration information. The combination of other types of first configuration information and priority rules can be defined similarly.

[0076] Optionally, the second configuration information includes at least one of the following: a side link resource pool period, used to indicate the repetition time interval of the side link resource pool configuration; the side link resource pool configuration, used to indicate the first time domain resources contained in the side link resource pool within one side link resource pool period, wherein the first time domain resources include the time slot and / or the symbol; the offset of the side link resource pool period, used to indicate the relative offset of the starting position of the side link resource pool period relative to the boundary of the specified frame number; the offset of the side link resource pool configuration, used to indicate the relative offset of the side link resource pool configuration relative to the boundary of the side link resource pool period.

[0077] The sidelink resource pool period indicates the repetition time interval of the sidelink resource pool configuration. For example, when the period is configured as 40 ms, the time domain resource configuration in the indicated Sidelink resource pool is repeated with a period of 40 ms.

[0078] Specifically, the sidelink time domain resource configuration may indicate a slot index within a period, where the indicated slot is a resource in the sidelink resource pool. The indicated slot index is a sequential number of all slots included in the sidelink resource pool period.

[0079] Alternatively, the sidelink time domain resource configuration indicates time slots within the sidelink resource pool period in a bitmap format. The length of the bitmap sequence is less than or equal to the period value, and each bit in the bitmap corresponds to a slot within the period. When the corresponding bitmap indication bit is "1," it indicates that the corresponding slot is a resource in the sidelink resource pool; when the corresponding bitmap indication bit is "0," it indicates that the corresponding slot is not a resource in the sidelink resource pool. When the second configuration information indicates an offset within the period for the sidelink time domain resource configuration, the corresponding indication of the bitmap sequence begins by offsetting the offset value from the sidelink resource pool period boundary.

[0080] Specifically, it includes at least one of the following methods:

[0081] The first way: In one slot, it indicates the number n of sidelink symbols used for sidelink communication.

[0082] The second method: In a slot, the symbols used for sidelink communication are indicated based on a slot format indication (SFI).

[0083] The third method: In a slot, the number n of symbols used for sidelink communication and the starting symbol position k used for sidelink communication are indicated.

[0084] In addition, in all slots included in the sidelink resource pool indicated in the second configuration information, the sidelink symbol configuration in each slot may be the same or different.

[0085] When the sidelink symbol configuration in each slot is the same, the sidelink symbol configuration is indicated only once in the second configuration information.

[0086] When the sidelink symbol configuration in each slot is independent, the second configuration information indicates the corresponding sidelink symbol configuration for each slot;

[0087] The second configuration information may further group the indicated multiple slots, with the slots in each group having the same Sidelinksymbol configuration, and different slot groups having independent Sidelink symbol configurations, which are indicated separately.

[0088] Optionally, the offset is a value pre-configured by the system; the offset is the number of downlink time slots included in the side link resource pool period; the offset is the sum of the number of downlink time slots and flexible time slots included in the side link resource pool period; when the first configuration information indicates that the flexible resources are available to the side link, the offset is the number of downlink time slots included in the side link resource pool period; when the first configuration information indicates that the flexible resources are not available to the side link, the offset is the sum of the number of downlink time slots and flexible time slots included in the side link resource pool period.

[0089] Specifically, when the offset indicated in the second configuration information is the Sidelink resource pool period offset, the indicated offset refers to the offset of the starting position of the Sidelink resource pool period relative to the system frame number SFN (Systemframe number) or direct link frame number DFN (Direct Frame Number) boundary.

[0090] When the offset indicated in the second configuration information is the offset of the Sidelink time domain resource configuration within the period, the indicated offset refers to the relative offset of the Sidelink time domain resource indication information indicated in the second configuration information, such as a bitmap, relative to the boundary of the Sidelink resource pool period.

[0091] When offset represents the offset of the Sidelink time domain resource configuration within a period, the offset can be a preconfigured value or implicitly determined according to a predefined rule and does not need to be explicitly indicated in the second configuration information. For example, the offset value is equal to the number of DL slots within the Sidelink resource pool period, or the offset is equal to the sum of the number of DL slots and the number of F slots within the Sidelink resource pool period, or the offset value is determined according to the first configuration information. For example, when the first configuration information indicates that F resources are unavailable, the offset is equal to the sum of the number of DL slots and the number of F slots within the Sidelink resource pool period; when the first configuration information indicates that F resources are available, the offset is equal to the number of DL slots within the Sidelink resource pool period.

[0092] It should be noted that multiple sidelink resource pools can be configured on the same sidelink resource, and the above-mentioned sidelink resource pool configuration instructions are independent for each resource pool.

[0104] In order to better understand the technical solutions provided in the above embodiments, the following scenarios are also provided for better understanding:

[0105] Scenario 1:

[0106] The UE receives the cell system broadcast message, obtains the first configuration information (also called type 1 first configuration information) and the second configuration information configured by the base station, and further determines the time domain resource configuration in the Sidelink resource pool.

[0107] Figure 6 This is a resource configuration diagram based on scenario 1 according to an embodiment of the present disclosure. Figure 6As shown, the first configuration information received by the UE indicates that the cell-common F resources are not available for Sidelink (i.e., not enabled). The cell-common F resources are indicated by the base station through a system broadcast message, that is, the UE is determined by the DL, F, and UL resources indicated in the time domain resource type configuration (TDD-UL-DL-SlotConfig) indicated by the configuration on the cellular communication link, where slot #7, #8, and #9 are indicated as Fslots. The second configuration information indicates that the Sidelink resource pool period is 40ms. Taking the length of each slot as 1ms as an example, the second configuration information indicates a 40-bit bitmap sequence for indicating Sidelink slots.

[0108] Figure 7 This is another resource configuration diagram based on scenario 1 according to an embodiment of the present disclosure. Figure 7 As shown, among the multiple slots included in the Sidelink resource pool indicated in the second configuration information, slot #7, #8, and #9 are F slots. According to the instruction of the first configuration information, the F resource cannot be used as a Sidelink resource. The time domain resources included in the actual Sidelink resource pool include slots whose bits corresponding to all bitmap sequences are "1" except for the F slot.

[0109] Scene 2

[0110] The UE receives a dedicated RRC message from the base station, which indicates UE-specific first configuration information (also called type 2 first configuration information) and second configuration information to the UE. The UE determines the time domain resource configuration in the sidelink resource pool based on the configuration indication. Here, because the first configuration information and the second configuration information are indicated to the UE via UE-specific signaling, the sidelink resource pool determined by the UE based on the corresponding indication is a UE-specific sidelink resource pool or a group-specific sidelink resource pool of the sidelink communication group to which the UE belongs.

[0111] Figure 8 This is a resource configuration diagram based on scenario 2 according to an embodiment of the present disclosure. Figure 8 As shown, the first configuration information received by the UE indicates that the F resource is available for Sidelink (i.e., it is enabled), and the second configuration information indicates that the Sidelink resource pool period is 40ms. Taking the length of each slot as 1ms as an example, the corresponding slot index of the Sidelink slot indicated in the second configuration information is slot#1, #3, #5, ..., #39.

[0112] in addition, Figure 9This is another resource configuration diagram based on scenario 2 according to an embodiment of the present disclosure. Figure 9 As shown, the cellular communication resource structure configured by the base station is as follows: slots #0 to #4 are DL slots, slots #31 to #39 are UL slots, and the rest are F slots. Based on the instructions of the first and second configuration information, the UE uses the F resources as sidelink resources. The UE can determine that the actual sidelink resource pool contains the following slots: slots #5, #7, #9, ..., #37, and #39.

[0113] Scene 3

[0114] Figure 10 This is a resource configuration diagram based on scenario three according to an embodiment of the present disclosure. Figure 10 As shown, the UE receives the cell system broadcast message and obtains the first configuration information and the second configuration information configured by the base station. Among them, the first configuration information received by the UE indicates that the cell common F resource is available for Sidelink, and the second configuration information indicates that the Sidelink resource pool period is 10ms. Taking the length of each slot as 1ms as an example, the second configuration information indicates a 10-bit bitmap sequence for indicating Sidelink slots, indicating slot #4, #5, and #6 as Sidelink slots respectively. In addition, the second configuration information also indicates symbol #7 to #13 in each Sidelink slot as Sidelink resources.

[0115] Figure 11 This is another resource configuration diagram based on scenario three according to an embodiment of the present disclosure. Figure 11 As shown, among the multiple slots included in the Sidelink resource pool indicated in the second configuration information, slot#4 is a DL slot. The UE determines, based on the configuration indication, that slot#4 is not a resource in the Sidelink resource pool. All symbols in slot#5 are F symbols. The UE determines that symbol#7 to #13 in slot#5 are resources in the Sidelink resource pool. Slot#6 is a UL slot. The UE determines that slot#6 is a Sidelink resource.

[0116] Scene 4

[0117] Figure 12 This is a resource configuration diagram based on scenario 4 according to an embodiment of the present disclosure. Figure 12As shown, the UE receives the cell system broadcast message and obtains the first configuration information and the second configuration information configured by the base station. Among them, the type 1 first configuration information received by the UE indicates that the cell common F resource is not available for Sidelink. In addition, the UE also receives a dedicated RRC message from the base station, indicating the UE-specific type 2 first configuration information, which indicates that the F resource indicated in the first node dedicated configuration signaling is available for Sidelink. Figure 12 As shown in the figure above, the UE determines the configuration of the cell common F resource according to the configuration instruction of the base station on the cellular communication resource. Slot #3, #4, #5, and #6 are F slots. Figure 12 As shown in the figure below, after the base station reconfigures the F resources dedicated to the first node via RRC messages, slots #4 and #5 are F slots. Furthermore, the system-defined priority rule states that when a UE obtains multiple types of first indication information with different configuration instructions for the same F resource, the indication of the type 2 first configuration information prevails. This means that the indication of the type 1 first configuration information is invalid, and the F resources in slots #4 and #5 are sidelink available resources for this UE.

[0118] The second configuration information indicated in the broadcast message indicates that the Sidelink resource pool period is 10ms. Taking the length of each slot as 1ms as an example, the second configuration information indicates that the Sidelink resource pool includes slots #2, #3, #4, #5, #6, #7, and #8.

[0119] Figure 13 This is another resource configuration diagram based on scenario 4 according to an embodiment of the present disclosure. Figure 13 As shown in the above figure, according to the above configuration information, slot #3, #4, #5, and #6 are cell common F resources. The UE can determine based on the type 1 first configuration information indicated by the broadcast message that the corresponding slot is not a resource in the Sidelink common resource pool, and the Sidelink common resource pool includes slot #7 and #8.

[0120] like Figure 13 As shown in the following figure, slot #4 and #5 are F slots indicated by the UE-specific configuration, slot #6 is the UL slot indicated by the UE-specific configuration, and the type 2 first configuration information indicated in the UE-specific configuration indicates that F resources are available. Then, slot #4, #5, and #6 are resources in the UE-specific Sidelink resource pool, or resources in the Sidelink resource pool dedicated to the Sidelink communication group to which the UE belongs.

[0121] Scene 5

[0122] Figure 14 This is a resource configuration diagram based on scenario five according to an embodiment of the present disclosure. Figure 14 As shown, the second configuration information indicates that the sidelink resource pool period is 10ms, and the symbols used for sidelink in each slot are configured identically, namely symbols #5 through #11. For example, if each slot is 1ms long, the second configuration information indicates the 10-bit bitmap sequence "00111 11000" to indicate sidelink slots. This indicates the time domain resource configuration in the sidelink resource pool.

[0123] Figure 15 This is another resource configuration diagram based on scenario five according to an embodiment of the present disclosure. Figure 15 As shown in the figure, in another example, the second configuration information indicates that the sidelink resource pool period is 40ms, with 10ms as a group. The sidelink symbols in the slots within the same group have the same configuration, and are divided into four groups within the period. Taking a slot length of 1ms as an example, the second configuration information indicates slots #1, #3, #5, ..., #39 as sidelink slots. The sidelink symbols in the first group are configured as all symbols in the slots, the sidelink symbols in the second group are configured as slots #7 to #13, the sidelink symbols in the third group are configured as slots #4 to #8, and the sidelink symbols in the fourth group are configured as slots #11 and #12. The time domain resource configuration of the sidelink resource pool indicated in the second configuration information is shown in the figure.

[0124] Scene 6

[0125] On the dedicated carrier for sidelink communications, the system preconfigures first and second configuration information for the common sidelink resource configuration. The second configuration information indicates that the sidelink resource pool contains all time domain resources. For example, when indicated by a bitmap, the bitmap sequence is an all-ones sequence. Furthermore, the dedicated carrier has preconfigured time domain resource types. For example, all time domain resources are UL resources, or both F and UL resources, with the positions of the F and UL resources preconfigured by the system.

[0126] When the UE operates on a dedicated carrier, resources in the sidelink resource pool are determined through pre-configured first configuration information and second configuration information.

[0127] When the first configuration information indicates that F resources are available, then according to the instruction of the second configuration information, all time domain resources on the dedicated carrier are resources in the Sidelink resource pool. When the first configuration information indicates that F resources are unavailable, then the Sidelink resources include all UL resources.

[0128] Scene 7

[0129] The resource partitioning units used by the UE and the base station on the cellular communication link can differ from the resource partitioning units used by the UE on the sidelink. This means that the subcarrier spacing and slot length of the cellular communication uplink may differ from the subcarrier spacing and slot length of the sidelink. In this case, the indication of the time domain resources contained in the sidelink resource pool needs to be converted according to the resource partitioning units of the two.

[0130] Figure 16 This is a resource configuration diagram based on scenario seven according to an embodiment of the present disclosure. Figure 16 As shown, the slot length of the UE's cellular communication uplink is 0.5ms, the slot length of the Sidelink resource is 1ms, the first configuration information obtained by the UE from the base station indicates that F resources are available, the Sidelink resource pool period indicated in the second configuration information is 10ms, and the corresponding bitmap sequence is "00011 00011", where each bit corresponds to a slot on the Sidelink.

[0131] The UE determines the corresponding time domain resource type based on the DL, F, and UL resources indicated in the time domain resource type configuration indicated on the cellular communication link. Slots #14 to #19 on the cellular communication link are F slots, and the others are DL slots. Based on the pre-configured information, the UE can determine that the time domain resources included in the sidelink resource pool are sidelink slots #8 and #9.

[0132] Scene 8

[0133] Figure 17 is a resource configuration diagram based on scenario eight according to an embodiment of the present disclosure, such as Figure 17 As shown, the second configuration information indicates an offset, which is defined as the offset of the sidelink resource pool period relative to the SFN or DFN boundary. The sidelink resource pool period is determined based on the offset. The second configuration information indicates offset = 5ms and the sidelink resource pool period = 20ms. The period window of the sidelink resource pool is shown in the figure.

[0134] Figure 18is another resource configuration diagram based on scenario eight according to an embodiment of the present disclosure, such as Figure 18 As shown, the second configuration information indicates the offset, and the offset is defined as the offset of the Sidelink time domain resource configuration within the period, then the time domain indication of the Sidelink resource pool is determined according to the configuration of the offset. Take the bitmap indicating the slot contained in the Sidelink resource pool as an example. Figure 18 As shown, the Sidelink resource pool period is 10ms, offset=4ms, and slot length is 1ms, so the corresponding bitmap sequence length is 6, starting from slot#4 in the period.

[0135] In another example, the offset is a system predefined value, and the offset value is equal to the number of DL slots in the resource configuration of the cellular communication. The UE determines the corresponding offset value according to the resource configuration indication on the cellular communication link.

[0136] Scene Nine

[0137] The base station configures and indicates multiple sidelink resource pools through a system broadcast message, and indicates corresponding second configuration information and first configuration information for each resource pool respectively.

[0138] Figure 19 is a resource configuration diagram based on scenario nine according to an embodiment of the present disclosure, such as Figure 19 As shown, Figure 19 As shown, the base station is configured with two Sidelink resource pools, wherein the second configuration information is a common configuration, the bitmap indication is "00000 01111", the first configuration information of the first Sidelink resource pool (the upper resource pool) indicates that F resources are unavailable, and the first configuration information of the second Sidelink resource pool (the lower resource pool) indicates that F resources are available. The UE can accordingly determine that the first Sidelink resource pool includes slots #8 and #9, and the second Sidelink resource pool includes slots #6 to #9.

[0139] Scene 10

[0140] On the sidelink dedicated carrier, the system preconfigures first configuration information, namely, type 0 first configuration information, indicating that F resources are available. Furthermore, the UE obtains type 1 first configuration information from the base station, indicating that F resources are unavailable. According to the system's predefined rules for using first configuration information, if a UE has both type 0 and type 1 first configuration information, and both configurations indicate the same F resources, the indication in the type 1 first configuration information takes precedence, and the corresponding indication in the type 0 first configuration information becomes invalid.
