Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a method, device and system for configuring an uplink reference signal that supports bandwidth expansion. Background Art

[0002] The minimum channel bandwidth supported by the current fifth generation mobile communication technology (5th Generation Mobile Communication Technology, referred to as 5G) New Radio (NR) is 5MHz. With the growing demand for dedicated spectrum with available bandwidth less than 5MHz, the existing standards need to be enhanced to support channel bandwidth less than 5MHz. According to the current protocol, there are the following problems: 1. The user equipment (UE) supports 3MHz small bandwidth scheduling, but the corresponding configuration options are not reflected in the positioning information exchange process, resulting in the network being unable to execute the small bandwidth scheduling strategy under bandwidth shortage conditions, affecting the user experience; 2. The UE is a device that supports millimeter waves, but the positioning information exchange process does not include 800MHz, 1600MHz and 2000MHz bandwidth options, resulting in the network being unable to utilize millimeter wave bandwidth resources under congestion, causing resource waste and scheduling inefficiency.

[0065] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0066] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0067] In related technologies, in addition to the Sub-6 GHz frequency band, millimeter waves between 30GHz and 300GHz are also an important part of 5G. Its advantages lie not only in the continuous 400MHz and 600MHz spectrum and up to 4Gbps-5Gbps uplink and downlink rates, but also in the ability to integrate with various cutting-edge technologies to meet the needs of various emerging vertical applications, while providing stable wireless data transmission while being flexibly deployed. In the 3GPP standard, generally speaking, frequency bands above 6GHz are collectively referred to as FR2 bands, which are further subdivided into two sub-bands FR2-1 (24250MHz–52600MHz) and FR2-2 (52600MHz–71000MHz), while those below 6GHz are referred to as FR1 bands.

[0068] For the scenario where the Next Generation Radio Access Network (NG-RAN) node is gNB (gNodeB), the core network positioning element location management function starts the positioning information exchange process and requests the UE's positioning information from the NG-RAN node (also known as the base station).

[0069] In order to control out-of-band interference and ensure the quality of in-band signals, such as Figure 1 As shown, all physical resource blocks within the channel bandwidth of the user equipment but not covering the minimum guard band can be used. 3GPP Long Term Evolution (LTE) and NR both define channel bandwidth (Channel Bandwidth), guard bandwidth (Guardband) and transmission bandwidth configuration (Transmission Bandwidth Configuration, referred to as TBC). From the RF perspective, insertion loss refers to the degree of signal loss caused by the filter, and the guard bandwidth / transition band is the frequency interval from the cutoff frequency (the frequency at which the insertion loss is equal to 3dB) to the maximum insertion loss value. The guard bandwidth is a frequency band used to suppress adjacent channel interference and reduce the error vector magnitude (EVM). It is located at the edge of the channel bandwidth and is not used to transmit data.

[0070] LTE provides several available channel bandwidths of 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz. The protection bandwidth of LTE accounts for 10% of the channel bandwidth (except 1.4MHz). For LTE in the Orthogonal Frequency Division Multiple Access (OFDMA) system, channels are multiplexed in resource elements (RE) and resource blocks (RB). The specific protection bandwidth configuration is shown in the following table:

[0071] Channel bandwidth 1.4MHz 3MHz 5MHz 10MHz 15MHz 20MHz Number of RBs in the frequency domain 6 15 25 50 75 100 Maximum available bandwidth / MHz 1.08 2.7 4.5 9 13.5 18 Unilateral protection bandwidth / kHz 160 150 250 500 750 1000

[0072] However, the protection bandwidth of NR is different from that of LTE in the following three aspects:

[0073] 1) The ratio of the protection bandwidth to the channel bandwidth is not fixed. In order to design the protection bandwidth according to the actual interference situation, such as Figure 2 As shown, NR only specifies the minimum guard band. For FR1 and FR2, the sum of the minimum guard bands on both sides accounts for 2% to 21% and 5% to 7% of the channel bandwidth respectively.

[0074] 2) The protection bandwidths on both sides of the channel bandwidth may be different, that is, Figure 2 asymmetric as shown in;

[0075] 3) When the channel bandwidth is determined, the number of PRBs used by LTE is fixed, while the number of PRBs used by NR can be changed.

[0076] The transmission bandwidth configuration specifically refers to the maximum number of resource blocks (RBs) available within the channel bandwidth, denoted by NRB, and the channel bandwidth is denoted by BWChannel. According to the 3GPP protocol, the minimum guard bandwidth can be calculated using the formula (BWChannel x1000(kHz)-NRB*SCS*12) / 2-SCS / 2, that is, the minimum guard band = (channel bandwidth-maximum number of resource blocks*12*subcarrier spacing-subcarrier spacing) / 2.

[0077] Therefore, the minimum bandwidth of NR designed for a specific UE channel bandwidth and SCS is as follows (in kHz):

[0078]

[0079] The current minimum channel bandwidth supported by 5G NR is 5MHz. With the growing demand for dedicated spectrum with available bandwidth less than 5MHz, the existing standards need to be enhanced to support channel bandwidth less than 5MHz.

[0080] In the current protocol, the basic process of Class 1 positioning is as follows:

[0081]

[0082]

[0083] According to the current protocol, there are the following problems:

[0084] The UE supports 3MHz small bandwidth scheduling, but the corresponding configuration options are not reflected in the positioning information exchange process, resulting in the network being unable to implement the small bandwidth scheduling strategy under bandwidth shortage conditions, affecting user experience;

[0085] The UE is a device that supports millimeter waves, but the bandwidth options of 800MHz, 1600MHz and 2000MHz are not included in the positioning information exchange process. As a result, the network cannot utilize millimeter wave bandwidth resources under congested conditions, causing resource waste and inefficient scheduling.

[0086] Based on the above requirements and reason analysis, the current 3GPP Rel-17 protocol cannot meet the NR positioning enhancement requirements and needs to be standardized through a new standardization method to meet the network's requirements for independently controlling the positioning bandwidth configuration of each type of UE in bandwidth-limited or millimeter wave scenarios.

[0087] In order to solve the above-mentioned problem, relevant solutions are provided in the embodiments of the present application, which are described in detail below.

[0088] According to an embodiment of the present application, a method embodiment of an uplink reference signal configuration method supporting extended bandwidth is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0089] Figure 3 is a flowchart of a method for configuring an uplink reference signal supporting bandwidth extension according to an embodiment of the present application, such as Figure 3 As shown, the method comprises the following steps:

[0090] Step S302: The base station receives a positioning information request message for the terminal device sent by a location management function (LMF) entity, and initializes a positioning information exchange process, wherein the positioning information request message is used by the location management function entity to request the positioning information of the terminal device from the base station;

[0091] Step S304, when the positioning information request message includes a requested sounding reference signal SRS transmission characteristics field (Requested SRS Transmission Characteristics IE), the base station applies the requested SRS transmission characteristics field when configuring SRS transmission for the terminal device, wherein the requested SRS transmission characteristics field includes configuration information of supporting an extended small bandwidth for the FR1 frequency band and / or supporting an extended large bandwidth for the FR2 frequency band.

[0092] According to the above steps, when the positioning information request message includes the requested SRS transmission characteristics field, the base station applies the requested SRS transmission characteristics field when configuring SRS transmission for the terminal device, thereby achieving the purpose of meeting the new air interface positioning enhancement requirements, thereby achieving the technical effect of meeting the network's requirements for independently controlling the positioning bandwidth configuration of each type of terminal device in bandwidth-limited or millimeter wave scenarios.

[0093] Before step S302, the base station receives a radio resource control RRC message sent by the terminal device that carries the terminal device's support capability for extended bandwidth, and determines whether to configure SRS extended bandwidth for the terminal device according to the support capability for extended bandwidth. The above RRC message includes but is not limited to: RRC establishment request message or RRC recovery request message.

[0094] The SRS transmission characteristic field requested in step S304 includes configuration information for supporting an extended small bandwidth of the FR1 band and / or supporting an extended large bandwidth of the FR2 band, wherein the extended small bandwidth of the FR1 band includes: a channel bandwidth less than 5 MHz; the extended large bandwidth of the FR2 band includes: a channel bandwidth greater than 400 MHz.

[0095] In addition, it can be understood that, when the base station can provide positioning information, the base station sends a positioning information response message to the location management function entity in response to the positioning information request message; and in the following cases, the base station sends a positioning information failure message to the location management function entity in response to the positioning information request message, for example:

[0096] 1. When the positioning information request message contains the requested SRS transmission characteristics field and the base station cannot configure any SRS transmission for the terminal device, a positioning information failure message is sent to the location management function entity in response to the positioning information request message.

[0097] 2. When the handover process of the terminal device is triggered, the base station sends a positioning information failure message carrying a cause value (appropriate cause value) corresponding to the handover situation to the location management function entity.

[0098] 3. When the base station is unable to provide positioning information, the base station sends a positioning information failure message to the location management function entity in response to the positioning information request message.

[0099] Optionally, uplink reference signal configuration scenarios supporting extended bandwidth include but are not limited to the following two scenarios: 1. The requested SRS transmission characteristic field contains configuration information for supporting an extended large bandwidth for the FR2 frequency band, and the base station sends a positioning information response message to the location management function entity; 2. The requested SRS transmission characteristic field contains configuration information for supporting an extended small bandwidth for the FR1 frequency band, and the base station sends a positioning information failure message to the location management function entity.

[0100] The following describes the above two scenarios respectively:

[0101] Scenario 1: For mmWave positioning configuration, and the scenario where positioning information exchange is successful, in this scenario, the NG-RAN node is the gNB; the LMF sends a positioning information request (POSITIONING INFORMATION REQUEST) message to the gNB, which contains the requested SRS transmission characteristics field (Requested SRS Transmission Characteristics IE), such as Figure 4 As shown, the following steps are included:

[0102] Step S402: The base station receives a radio resource control RRC message sent by the terminal device and carrying the terminal device's support capability for extended bandwidth. Optionally, the RRC message includes: an RRC establishment request message or an RRC recovery request message.

[0103] Specifically, the Next Generation Node B-Central Unit (gNB-CU) receives the radio resource control resumption (RRC Resume) request message sent by the terminal, where the gNB-CU refers to the control plane part of the base station, which is responsible for handling network control, scheduling and management functions, communicating with the user equipment and managing the radio resources of the base station.

[0104] It is understandable that the extended bandwidth support capability includes: the support capability of extending a small bandwidth for the FR1 frequency band and / or the support capability of extending a large bandwidth for the FR2 frequency band.

[0105] Optionally, it is determined that SRS extended bandwidths of 800 MHz, 1600 MHz and 2000 MHz can be configured for the terminal according to the support capability of the terminal device for the extended bandwidth carried in the RRC recovery request message.

[0106] It should be noted that, when the requested SRS transmission characteristic field includes the spatial relationship information and the period list of each SRS resource, the base station determines a one-to-one mapping relationship between the spatial relationship information and the period list item of each SRS resource item.

[0107] In step S404, the LMF sends a positioning information request message including the requested SRS transmission characteristics field to the gNB to start the positioning information exchange process, where the positioning information exchange process refers to the process of transmitting and exchanging positioning information through different communication methods and technologies.

[0108] Exemplarily, the field containing the SRS configuration requested by the UE (Requested SRS TransmissionCharacteristics) is defined as follows:
