Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method for configuring a sidelink resource pool, a network device, a terminal, and a storage medium. Background Art

[0002] In Sidelink communication, when there is traffic to be transmitted between user equipments (UEs), the traffic data between the UEs does not need to be forwarded by the base station, but is directly transmitted from the data source UE to the target UE through the air interface. The wireless link between the UEs is called a sidelink.

[0003] In sidelink communication, both the sending and receiving of information are performed in a resource pool. The terminal determines the sending resource pool and the receiving resource pool through network configuration or pre-configuration, and the UE only sends sidelink information in the sending resource pool and only receives sidelink information sent by other UEs in the receiving resource pool. The sending resource pool of UE-A can be the receiving resource pool of UE-B.

[0004] However, during the SL (Sidelink) positioning process, when the UE fails to select a transmission resource that meets the requirements through sensing, it will increase the RSRP (reference signal received power) detection threshold until the number of selected candidate resources meets the requirements, and transmit the SL PRS (positioning reference signal) and / or SL positioning information (positioning assistance data, positioning request, positioning feedback, positioning measurement quantities, and positioning results, etc.) on the corresponding resources. At this time, due to the high RSRP threshold, the selected transmission resources are more interfered, which will affect the SL positioning performance (when the resources are more scarce, the RSRP threshold is larger, and this impact is more serious). Or, in some cases, the random selection method is switched during the sensing process, and interference problems will also be faced at this time. In addition, due to the high latency requirements for SL positioning (such as public safety scenarios, vehicle-to-everything scenarios, etc.), if the transmission of SL PRS and / or SL positioning information is delayed, it will affect the positioning latency, and thus also affect the positioning performance. Summary of the Invention

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein.

[0023] For ease of description, some of the nouns or terms involved in this application document are described below:

[0024] SL: Sidelink, sidelink.

[0025] PRS: positioning reference signal, positioning reference signal.

[0026] BWP: Bandwidth part, bandwidth part.

[0027] NR: New radio, new radio.

[0029] UE: User Equipment, user equipment.

[0030] Sub-channel: sub-channel.

[0031] RB: Resource block, resource block.

[0032] RE: Resource element, resource element.

[0033] PSFCH: Physical Sidelink Feedback Channel, physical sidelink feedback channel.

[0034] HARQ: Hybrid Automatic Repeat Request, hybrid automatic repeat request.

[0035] SCI: Sidelink control information, Sidelink control information.

[0036] DCI: Downlink control information, downlink control information.

[0037] PC5-RRC: ProSe Direct Communication 5-Radio Resource Control, direct communication - radio resource control.

[0038] MAC: Medium Access Control layer Control Element, medium access control layer control element.

[0039] It should be noted that the method provided by the present invention is applicable to NR sidelink and its subsequent evolved versions.

[0040] The overall design idea of NR sidelink is similar to that of LTE sidelink, mainly for direct communication, and the capabilities of the 5G NR network are correspondingly extended, that is, a sidelink design based on the NR uplink is adopted. Considering the implementation complexity and gain, only the CP-OFDM (Cycle Prefix-Orthogonal Frequency Division Multiplexing) waveform is supported, and sidelink transmission based on the DFT-S-OFDM (Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing) waveform is not supported.

[0041] In actual network deployment, NR sidelink involves multiple network coverage states, namely full network coverage, no network coverage, and partial network coverage. Further, for different network coverage scenarios, NR sidelink supports a network control-based resource allocation scheme (mode 1) and a UE self-selected resource scheme (mode 2). To balance efficiency and fairness, and to achieve flexible resource usage and indication, NR sidelink introduces SCI, whose design idea is similar to DCI, aiming to indicate information such as the resources occupied by the UE and modulation and coding.

[0042] NR sidelink supports multiple transmission types, including unicast, multicast, and broadcast, where multicast is further divided into connection-based multicast and connectionless multicast. To ensure the reliability of data transmission, NR sidelink supports a feedback mechanism, and uses the PSFCH channel to transmit feedback information. The corresponding HARQ feedback methods are divided into two types: HARQ-ACK / NACK and HARQ-NACK, and the latter is only applicable to the connectionless multicast mode.

[0043] NR sidelink supports BWP configuration, and its definition is similar to that of NR BWP. On a carrier, at most one BWP can be (pre)-configured, and this BWP is used for both sidelink transmission and reception simultaneously. In licensed spectrum, if the UE configures both sidelink BWP and uplink BWP simultaneously, it is necessary to ensure that the SCS on both links is the same. Further, multiple resource pools can be configured on one sidelink BWP, with a maximum of 16 receiving resource pools and 8 transmitting resource pools supported. The resource pools are divided into multiple sub-channels in the frequency domain, and these sub-channels refer to the set of multiple (not less than 10) consecutive and non-overlapping RBs in a single slot. Further, sidelink resource allocation, sensing, and resource selection are all based on sub-channels as the smallest unit.

[0044] In sidelink communication, both the sending and receiving of information are carried out in resource pools. The terminal determines the sending resource pool and receiving resource pool through network configuration or pre-configuration, and the UE only sends sidelink information in the sending resource pool and only receives sidelink information sent by other UEs in the receiving resource pool. The sending resource pool of UE-A can be the receiving resource pool of UE-B.

[0045] Specifically, the receiving resource pools do not distinguish types, and the sending resource pools are divided into the following types:

[0046] Normal resource pool: The sending resource pool used by the terminal when working in autonomous selection of transmission resources;

[0047] Scheduled resource pool: The sending resource pool used by the terminal when working in network-allocated transmission resources. At this time, the terminal receives the scheduling information sent by the network and determines the transmission resources allocated by the network in the scheduled resource pool;

[0048] Abnormal resource pool: The sending resource pool used by the terminal when working in autonomous selection of transmission resources. This resource pool is only used in some abnormal situations and uses a random selection method to select transmission resources;

[0049] Discovery resource pool: A dedicated resource pool used for the NR sidelink discovery process;

[0050] Power-saving resource pool: The NR sidelink communication resource pool used for power saving.

[0051] The above content introduces some related background technologies of the present invention to facilitate the subsequent understanding of the embodiments of the present invention.

[0052] According to an embodiment of the present invention, an embodiment of a method for configuring a sidelink resource pool is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system including at least a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0053] This method embodiment can also be executed in an electronic device, a similar control device or a computer terminal including a memory and a processor. Taking the electronic device as an example, the electronic device can include one or more processors and a memory for storing data. Optionally, the above-mentioned electronic device can also include a communication device for communication functions and a display device. Those of ordinary skill in the art can understand that the above structural description is only illustrative and does not limit the structure of the above-mentioned electronic device. For example, the electronic device can also include more or fewer components than the above structural description, or have a different configuration from the above structural description.

[0054] The processor can include one or more processing units. For example: the processor can include a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP) chip, a microcontroller unit (MCU), a field-programmable gate array (FPGA), a neural-network processing unit (NPU), a tensor processing unit (TPU), a processing device of an artificial intelligent (AI) type processor, etc. Among them, different processing units can be independent components or integrated in one or more processors. In some instances, the electronic device can also include one or more processors.

[0055] The memory can be used to store computer programs, such as the computer program corresponding to the configuration method of the sidelink resource pool in the embodiments of the present invention. The processor realizes the above-mentioned configuration method of the sidelink resource pool by running the computer program stored in the memory. The memory may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memories, or other non-volatile solid-state memories. In some instances, the memory may further include a memory remotely disposed relative to the processor, and these remote memories can be connected to the electronic device through a network. Examples of the above network include but are not limited to the Internet, an enterprise intranet, a local area network, a mobile communication network, and combinations thereof.

[0056] The communication device is used to receive or send data via a network. Specific examples of the above network may include a wireless network provided by a communication provider of a mobile terminal. In one instance, the communication device includes a network interface controller (NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one instance, the communication device may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly. In some embodiments of the present solution, the communication device is used to connect to mobile devices such as mobile phones and tablets, and can send instructions to the electronic device through the mobile devices.

[0057] Figure 1 is a flowchart of a configuration method of a sidelink resource pool according to an embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0058] Step S101, configure a first type of resource pool and a second type of resource pool for the terminal to transmit positioning-related information, where the positioning-related information includes a sidelink positioning reference signal and / or sidelink positioning information; wherein, the second type of resource pool is only used for transmitting positioning-related information when the terminal meets a preset rule; the first type of resource pool is not used for transmitting positioning-related information when the terminal meets a preset rule.

[0059] Specifically, the first type of resource pool and the second type of resource pool for transmitting positioning-related information can perform unidirectional transmission (send or receive) and / or bidirectional transmission (send and receive).

[0060] Optionally, the first type of resource pool and the second type of resource pool are configured according to configuration information, and the configuration information can be read from a preset configuration file.

[0061] Optionally, the configuration information can also be queried and obtained from a network database, and the configuration information required for the first type of resource pool and the second type of resource pool is pre-stored in the network database.

[0062] Specifically, the terminal uses the second type of resource pool to send or receive sidelink positioning reference signals and / or sidelink positioning information only when the preset rules are met. When the terminal does not meet the preset rules, the first type of resource pool can be used to send and receive the sidelink positioning reference signals and / or sidelink positioning information.

[0063] It should be noted that the preset rules are the rules for determining whether the terminal can normally process the sidelink positioning reference signals and / or sidelink positioning information in the first type of resource pool.

[0064] It can be understood that if the terminal meets the preset rules, it indicates that the terminal cannot normally process the sidelink positioning reference signals and / or sidelink positioning information in the first type of resource pool. At this time, the second type of resource pool is used to process the sidelink positioning reference signals and / or sidelink positioning information.

[0065] In some embodiments of the present invention, the first type of resource pool and the second type of resource pool include a positioning dedicated resource pool, and the positioning resource pool is dedicated to sending and receiving sidelink positioning reference signals and sidelink positioning information.

[0066] In the embodiments of the present invention, the first type of resource pool and the second type of resource pool for transmitting positioning-related information are configured for the terminal, and the positioning-related information includes sidelink positioning reference signals and / or sidelink positioning information; wherein, the second type of resource pool is only used for the transmission of positioning-related information when the terminal meets the preset rules; the first type of resource pool is not used for the transmission of positioning-related information when the terminal meets the preset rules. By setting the first type of resource pool and the second type of resource pool, when there are no suitable resources or the interference of the transmission resources in the first type of resource pool is relatively large, the terminal can use the second type of resource pool to send and receive sidelink positioning reference signals and / or sidelink positioning information according to the preset rules, thereby solving the technical problem that the sidelink positioning performance is affected when there are no suitable transmission resources and / or the interference of the transmission resources is relatively large.

[0067] Optionally, configuring the first type of resource pool and the second type of resource pool for transmitting positioning-related information for the terminal includes: configuring one second type of resource pool for the terminal.

[0068] It should be noted that multiple second type of resource pools can also be configured for the terminal.

[0069] Optionally, configuring the first type of resource pool and the second type of resource pool for transmitting positioning-related information for the terminal includes: configuring that the first type of resource pool is also used for transmitting non-positioning information.

[0070] Specifically, the first type of resource pool can be configured to transmit positioning-related information and non-positioning-related information. Correspondingly, in addition to the positioning dedicated resource pool, the first type of resource pool can also include one or more of a normal resource pool, a scheduling resource pool, an exception resource pool, a discovery resource pool, or an energy-saving resource pool.

[0071] Optionally, configuring the first type of resource pool and the second type of resource pool for the terminal to transmit positioning-related information includes: configuring the first frequency domain resource for transmitting the sidelink positioning reference signal and the second frequency domain resource for transmitting the sidelink positioning information in the second type of resource pool to satisfy: the first frequency domain resource and the second frequency domain resource do not overlap in the frequency domain, and / or, the starting points of the frequency domain resources of the first frequency domain resource and the second frequency domain resource are the same and the bandwidth of the first frequency domain resource is greater than the bandwidth of the second frequency domain resource.

[0072] Specifically, when configuring the second type of resource pool for the terminal, the configured first frequency domain resource and second frequency domain resource satisfy: the first frequency domain resource and the second frequency domain resource do not overlap at all (i.e., frequency division multiplexing). Exemplarily, the frequency domain interval between the frequency domain resource for transmitting the sidelink positioning reference signal and the frequency domain resource for transmitting the sidelink positioning information is X1 (X1 is a natural number) sub-channels / RBs / REs.

[0073] Specifically, when configuring the second type of resource pool for the terminal, the configured first frequency domain resource and second frequency domain resource satisfy: the starting points of the frequency domain resources of the first frequency domain resource and the second frequency domain resource are the same and the bandwidth of the first frequency domain resource is greater than the bandwidth of the second frequency domain resource.

[0074] Optionally, when configuring the second type of resource pool for the terminal, the configured first frequency domain resource and second frequency domain resource satisfy: the widths of the first frequency domain resource and the second frequency domain resource are less than or equal to X2 (X2 is a positive integer) sub-channels / RBs / REs.

[0075] Optionally, the sidelink positioning information includes at least one of positioning assistance data, a positioning request, a positioning feedback, positioning measurement quantities, and a positioning result.

[0076] Optionally, the preset rule is used to characterize the degradation of the sidelink positioning performance of the terminal.

[0077] Optionally, configuring the first type of resource pool and the second type of resource pool for the terminal to transmit positioning-related information includes: configuring the starting point of the frequency domain of the second type of resource pool to be the same as the starting point of the frequency domain of the bandwidth part or the carrier, or, configuring the ending point of the frequency domain of the second type of resource pool to be the same as the ending point of the frequency domain of the bandwidth part or the carrier, or, configuring the midpoint of the frequency domain of the second type of resource pool to be the same as the midpoint of the frequency domain of the bandwidth part or the carrier.

[0078] It can be understood that the above configuration is for configuring the frequency domain resources of the second type of resource pool.

[0079] Optionally, configuring a first type of resource pool and a second type of resource pool for a terminal includes: configuring that the second type of resource pool and the first type of resource pool do not overlap in the frequency domain.

[0080] Specifically, the fact that the second type of resource pool and the first type of resource pool do not overlap in the frequency domain can avoid frequency domain resource conflicts between the second type of resource pool and the first type of resource pool when processing communication information.

[0081] Optionally, configuring a first type of resource pool and a second type of resource pool for a terminal includes: configuring that the second type of resource pool is located in the intelligent transportation system frequency band.

[0082] Specifically, the second type of resource pool occupies time domain and frequency domain resources in the ITS band (Intelligent Transportation System band). Exemplarily, the second type of resource pool occupies the topmost or bottommost spectrum resources in the intelligent transportation system frequency band, and the bandwidth is R1 MHz (R1 > 0), where R1 is a preset value.

[0083] Optionally, configuring a first type of resource pool and a second type of resource pool for a terminal includes: configuring that the distance between the first type of resource pool and the second type of resource pool in the frequency domain is less than or equal to a first preset distance value, and / or, the distance between the first type of resource pool and the second type of resource pool in the time domain is less than or equal to a second preset distance value.

[0084] It can be understood that the fact that the distance between the first type of resource pool and the second type of resource pool in the frequency domain is less than or equal to a first preset distance value, and / or, the distance between the first type of resource pool and the second type of resource pool in the time domain is less than or equal to a second preset distance value can make the handover between the first type of resource pool and the second type of resource pool easier to implement.

[0085] Optionally, configuring a first type of resource pool and a second type of resource pool for a terminal includes: configuring that the frequency domain width of the second type of resource pool is greater than or equal to or less than the frequency domain width of the first type of resource pool.

[0086] Optionally, configuring a first type of resource pool and a second type of resource pool for a terminal includes: configuring that the second type of resource pool is located on the primary cell or the secondary cell in the carrier aggregation scenario.

[0087] Optionally, the method for configuring the sidelink resource pool further includes: configuring that when the terminal meets a preset rule, it switches from transmitting positioning-related information by the first type of resource pool to transmitting positioning-related information by the second type of resource pool.

[0088] Specifically, configure the preset rule as the switching condition of the resource pool. When the terminal meets the preset rule, it indicates that the performance of the first type of resource pool for transmitting positioning-related information degrades, and then switch to the second type of resource pool to transmit the positioning-related information.

[0089] Optionally, the method for configuring the sidelink resource pool further includes: when the frequency-domain width of the second type of resource pool is greater than or equal to the frequency-domain width of the first type of resource pool, configuring the second type of resource pool for the terminal further includes: when the positioning-related information to be transmitted is a sidelink positioning reference signal, configuring the terminal to extend the sequence length of the sidelink positioning reference signal to be transmitted, so as to map the sidelink positioning reference signal to the switched second type of resource pool to end.
