[Technical field]

[0001] TECHNICAL FIELD Embodiments of the present application relate to the field of communications, and in particular to a communication method and a communication device. [Background technology]

[0002] At present, enhanced mobile broadband (eMBB) user equipment (UE) exists in the 5G system. In addition, Internet of Things services (such as wearables, industrial sensors, video surveillance, etc.) have requirements for low cost and low complexity of terminal devices, so reduced capability (RedCap) UE is proposed. This type of UE is called low complexity (or reduced capability, or low cost) UE. Compared with eMBB UE, RedCap UE has one or more of the following characteristics: low device complexity and low device size.

[0003] Based on the above description, different types of UEs have different requirements. Currently, there is no related technology that can apply to the communication problem between RedCap UE and different network devices. Summary of the Invention [Means for solving the problem]

[0004] The embodiments of the present application provide a communication method and a communication device, in which a terminal device independently reports capability information supporting the transmission and / or reception of a reference signal, which solves the communication problem of a terminal device supporting the transmission and / or reception of a reference signal.

[0005] In order to solve the above technical problems, the embodiments of the present application provide the following technical solutions:

[0006] According to a first aspect, an embodiment of the present application provides a communication method, the communication method includes the steps of: a terminal device transmitting first capability information to a first network device, the first capability information indicating that the terminal device supports transmission and / or reception of the first information by using at most a first amount of resources, the first information including a reference signal; a terminal device transmitting second capability information to a second network device, the second capability information indicating that the terminal device supports transmission and / or reception of the second information by using at most a second amount of resources, the second information including at least one of data or control information; a terminal device acquiring first configuration information, the first configuration information indicating that an amount of resources configured for the first information is equal to or less than a first amount; and a terminal device acquiring second configuration information, the second configuration information indicating that an amount of resources configured for the second information is equal to or less than a second amount.

[0007] In the aforementioned technical solution, the terminal device may establish a communication connection to at least one network device. For example, the terminal device may report multiple capability information to the network device. The terminal device may report multiple capability information to one network device, or the terminal device separately reports multiple capability information to different network devices. For example, the terminal device transmits first capability information to a first network device, the first capability information indicating that the terminal device supports transmission and / or reception of the first information by using at most a first amount of resources, and the first information includes a reference signal. The terminal device transmits second capability information to a second network device (the second network device and the first network device may be the same network device), the second capability information indicating that the terminal device supports transmission and / or reception of the second information by using at most a second amount of resources, and the second information includes at least one of data or control information. The terminal device obtains first configuration information, and the first configuration information indicates that the amount of resources configured for the first information is equal to or less than a first quantity. The terminal device obtains second configuration information, and the second configuration information indicates that the amount of resources configured for the second information is equal to or less than a second amount. In this embodiment of the present application, the terminal device may report, by using the first capability information, that the terminal device supports the transmission and / or reception of the reference signal by using at most a first amount of resources, and the terminal device may report, by using the second capability information, that the terminal device supports the transmission and / or reception of the second information by using at most a second amount of resources. This avoids the terminal device from transmitting and / or receiving the second information by using the first amount of resources, which reduces the complexity of the terminal device and reduces the power consumption overhead of the terminal device.

[0008] In one possible implementation, the first quantity is greater than the second quantity.

[0009] In the above technical solution, the first quantity is the quantity of resources indicated by the first capability information, and the second quantity is the quantity of resources indicated by the second capability information. The first capability information is used to request resources corresponding to the first information (e.g., the first information is a reference signal), and the second capability information is used to request resources corresponding to the second information (e.g., the second information is data or control information). In this case, the first quantity is greater than the second quantity. In other words, the terminal device may request a large amount of resources for transmitting a reference signal and a small amount of resources for transmitting data. Therefore, the high-precision positioning requirements of the terminal device (e.g., RedCap UE) may be implemented without significantly increasing the complexity / cost / power consumption of the UE.

[0010] In one possible implementation, the first quantity belongs to a first set of quantities, and at least one quantity in the first set of quantities is greater than the second quantity; or The first quantity belongs to a first set of quantities, the second quantity is predefined, and at least one quantity in the first set of quantities is greater than the second quantity; the first quantity belongs to a first set of quantities and the second quantity belongs to a second set of quantities, and at least one quantity in the first set of quantities is greater than the second quantity; or the first quantity belongs to a first set of quantities and the second quantity belongs to a second set of quantities, and at least one quantity in the first set of quantities is greater than all quantities in the second set of quantities; or the first quantity is predefined and the second quantity is predefined, the first quantity being greater than the second quantity; or The first quantity is predefined and the second quantity is predefined, the first quantity being less than or equal to the second quantity.

[0011] In the above technical solution, the first quantity and the second quantity are determined separately by the terminal device. For example, the first quantity belongs to a first set of quantities, and at least one quantity in the first set of quantities is greater than the second quantity. The implementation form of the first set of quantities is not limited in this embodiment of the application. For example, the first set of quantities may include one component or may include multiple components, and the components are the quantities that constitute the first set of quantities. At least one quantity in the first set of quantities is greater than the second quantity. Therefore, the first quantity may be greater than the second quantity. The specific value of the first quantity is not limited in this specification.

[0012] For example, the first quantity belongs to a first set of quantities, the second quantity is predefined, and at least one quantity in the first set of quantities is greater than the second quantity, and the second quantity is predefined by the terminal device. For example, the terminal device predefines that the bandwidth of the second quantity is 20MHz, 40MHz, or 5MHz, or predefines that the bandwidth of the second quantity is 51 resource blocks (or 106 resource blocks, or 11 resource blocks). The first set of quantities may include one component or may include multiple components, and the components are quantities that constitute the first set of quantities. At least one quantity in the first set of quantities is greater than the second quantity. Thus, the first quantity may be greater than the second quantity. The specific value of the first quantity is not limited in this specification.

[0013] For example, the first quantity belongs to a first set of quantities, the second quantity belongs to a second set of quantities, and at least one quantity in the first set of quantities is greater than the second quantity. In this embodiment of the present application, the implementation of the first set of quantities and the second set of quantities is not limited. For example, the first set of quantities may include one component or may include multiple components, and the components are the quantities that make up the first set of quantities. The second set of quantities may include one component or may include multiple components, and the components are the quantities that make up the second set of quantities. At least one quantity in the first set of quantities is greater than the second quantity. Thus, the first quantity may be greater than the second quantity. The specific value of the first quantity is not limited herein.

[0014] For example, the first quantity belongs to a first set of quantities, the second quantity belongs to a second set of quantities, and at least one quantity in the first set of quantities is greater than all quantities in the second set of quantities. In this embodiment of the present application, the implementation of the first set of quantities and the second set of quantities is not limited. For example, the first set of quantities may include one component or may include multiple components, and the components are the quantities that make up the first set of quantities. The second set of quantities may include one component or may include multiple components, and the components are the quantities that make up the second set of quantities. At least one quantity in the first set of quantities is greater than all quantities in the second set of quantities. Thus, the first quantity may be greater than the second quantity. The specific value of the first quantity is not limited herein.

[0015] In this embodiment of the present application, the specific values ​​of the first quantity and the second quantity may be predefined. The terminal device may indicate whether the first quantity is valid by using the first capability information. In addition, the terminal device may indicate whether the second quantity is valid by using the second capability information. It should be noted that the terminal device may configure the first capability information and the second capability information separately. If the first quantity is greater than the second quantity, the high-precision positioning requirements of the terminal device (e.g., RedCap UE) may be implemented without significantly increasing the complexity / cost / power consumption of the UE. If the first quantity is equal to or less than the second quantity, the transmission bandwidth capability of the positioning reference signal may be less than the bandwidth capability of the data transmission, and the positioning reference signal may not be transmitted in the full bandwidth. This can effectively reduce the power consumption of the UE.

[0016] In one possible implementation, the resource is one or more of a bandwidth, a resource block, a carrier, a subband, a frequency range, a frequency segment, a frequency band, a subcarrier spacing, a bandwidth portion BWP, a frequency hopping interval, and a number of frequency hops within a particular time range.

[0017] In the above technical solution, the resource defined in this embodiment of the present application has multiple implementation forms. For example, the resource may be a bandwidth, or the resource may be a resource block. This is not limited in this embodiment of the present application. The related concepts of bandwidth, resource block, carrier, subband, frequency range, frequency segment, frequency band, subcarrier spacing, BWP, frequency hopping interval, and the number of frequency hops in a certain time range are not described again in this specification.

[0018] In one possible implementation, the method comprises: The terminal device transmits the third capability information to the first network device or the second network device. Further includes:

[0019] The third capability information is Whether the terminal device supports transmitting and / or receiving the first information in a carrier aggregation manner; and / or The terminal device supports transmission and / or reception of the first information by using up to M carriers, where M is a positive integer. Shows.

[0020] In the above technical solution, the third capability information indicates whether the terminal device supports the transmission and / or reception of the first information in a carrier aggregation manner. For example, the third capability information may be 1-bit indication information, and the indication information indicates whether the terminal device supports the transmission and / or reception of the first information in a carrier aggregation manner. In addition, the third capability information indicates that the terminal device supports the transmission and / or reception of the first information by using at most M carriers, where M is a positive integer. For example, the value of M may be carried in the third capability information. The terminal device transmits and / or receives the first information by using at most M carriers means that the maximum number of carriers used by the terminal device may be M carriers. Since the terminal device transmits the third capability information, the first network device or the second network device may determine whether the terminal device uses carrier aggregation and determine the number of carriers used for aggregation.

[0021] In one possible implementation, the method comprises: The terminal device transmits the fourth capability information to the first network device or the second network device. Further includes:

[0022] The fourth capability information is The terminal device does not support the transmission and / or reception of the second information in a carrier aggregation manner; or The terminal device supports transmission and / or reception of the second information by using up to N carriers, where N is a positive integer. Shows.

[0023] In the above technical solution, the fourth capability information indicates whether the terminal device supports the transmission and / or reception of the second information in a carrier aggregation manner. For example, the fourth capability information may be 1-bit indication information, and the indication information indicates that the terminal device does not support the transmission and / or reception of the second information in a carrier aggregation manner. In addition, the fourth capability information indicates that the terminal device supports the transmission and / or reception of the second information by using at most N carriers, where N is a positive integer. For example, the value of N may be carried in the fourth capability information. The terminal device transmits and / or receives the second information by using at most N carriers means that the maximum number of carriers used by the terminal device may be N carriers. Because the terminal device transmits the fourth capability information, the first network device or the second network device may determine that the terminal device does not use carrier aggregation and determine the number of carriers used for aggregation.

[0024] In one possible implementation, N is less than M, or N is less than or equal to M.

[0025] In the above technical solution, when N is less than M, the high-precision positioning requirement of the terminal device (e.g., RedCap UE) can be implemented without significantly increasing the complexity / cost / power consumption of the UE. N being less than or equal to M means that N is less than M or N=M. When N is less than M, the high-precision positioning requirement of the terminal device (e.g., RedCap UE) can be implemented without significantly increasing the complexity / cost / power consumption of the UE. When N=M, the transmission bandwidth capability of the positioning reference signal is equal to the bandwidth capability of data transmission. This simplifies the configuration manner of the transmission bandwidth of the positioning reference signal and the bandwidth of data transmission.

[0026] In one possible implementation, the method comprises: The terminal device transmits the fifth capability information to the first network device or the second network device. Further includes:

[0027] The fifth capability information is the terminal device supports generation of the first information according to the first algorithm; the terminal device supports generation of the first information according to a second algorithm; or The terminal device supports generation of the first information according to the first algorithm and the second algorithm. Shows.

[0028] The first algorithm and the second algorithm are different algorithms.

[0029] In the above technical solution, the algorithm of this embodiment of the present application may be a sequence generation method. The contents or quantities of the sequences generated by different algorithms are not completely the same. For example, the sequence ID used when the first algorithm generates a sequence is in the range of {0, ..., 1023}. For example, the sequence ID used when the second algorithm generates a sequence is in the range of {0, ..., 65535}.

[0162] In the embodiments of the present application, " / " may represent an "or" relationship between associated objects. For example, A / B may represent A or B. "And / or" may be used to indicate that there are three relationships between associated objects. For example, A and / or B may represent three cases: only A exists, both A and B exist, and only B exists. A and B may be singular or plural.

[0163] The terminal device in the embodiment of the present application may be called a terminal and may be a device having a wireless transceiver function. The terminal device may be located on land, including an indoor device, an outdoor device, a handheld device, or an in-vehicle device, may be located on the water surface (such as in a steamship), or may be located in the air (such as an aircraft, a balloon, or a satellite).

[0164] A terminal device in an mMTC scenario may be a reduced capability (REDCAP) terminal device. A REDCAP terminal device may also be referred to as a light terminal device. For example, a REDCAP terminal device in an NR system has a lower capability than that of a conventional terminal device. For example, compared with a conventional terminal device, a REDCAP terminal device has one or more of the following characteristics: a narrower supported bandwidth, a smaller number of configured antennas, a smaller maximum supported transmission power, a lower supported duplex capability (e.g., a conventional terminal device supports full-duplex frequency division duplex, and a REDCAP terminal device supports half-duplex frequency division duplex), and a weaker data processing capability (e.g., a REDCAP terminal device can process less data than a conventional terminal device in the same period, or a REDCAP terminal device takes a longer period than a conventional terminal device to process the same data). Thus, a REDCAP terminal device and a conventional terminal device may require different system information, a dedicated access network, a control channel with different performance, etc. A conventional terminal device may be a non-REDCAP terminal device, which mainly supports eMBB services and / or URLLC services. Compared to the REDCAP terminal device, the conventional terminal device may be considered as a high-capability terminal device or a terminal device with unlimited capabilities.

The base station in the 5G mobile communication system may also be called a transmission reception point (TRP) or a gNB. In the embodiment of the present application, the device configured to implement the function of the network device may be a network device, or may be a device, such as a chip system, that can support the network device in implementing the function. The device may be disposed on the network device or used together with the network device.

For example, the positioning server may be a location management function (LMF) or other functional entity that provides a positioning service.

[0168] The technical solutions provided in the embodiments of the present application may be applied to wireless communication between communication devices.

The technical solutions may be used for wireless communication between a scheduling entity and a lower entity. The scheduling entity may allocate resources to the lower entity. Those skilled in the art may use the technical solutions provided in the embodiments of the present application to perform wireless communication between other scheduling entities and lower entities, for example, wireless communication between a macro base station and a micro base station.

[0169] An embodiment of the present application provides a communication method. The method is applicable to a communication scenario between a terminal device and at least one network device, and may provide appropriate resources for the positioning service of different types of terminal devices. For example, to meet the communication requirements of various types of terminal devices, resources applicable to the positioning service of the REDCAP terminal device may be provided to the REDCAP terminal device. For example, the REDCAP terminal device supports a different bandwidth than a conventional terminal device, or supports a different aggregation level (AL) than a conventional terminal device, or supports a different number of candidate control channels than a conventional terminal device. In this embodiment of the present application, the terminal device transmits first capability information to a first network device, the first capability information indicating that the terminal device supports transmission and / or reception of the first information by using at most a first amount of resources, and the first information includes a reference signal.

[0170] In this embodiment of the present application, transfer can be understood as forwarding or reporting. Send means that the terminal device transmits information to the network device, for example, transmits reference signals, transmits data, or transmits control information. The data here may be data carried on a physical shared channel, and the reference signal does not belong to the data.

[0171] This embodiment of the present application relates to communication between a terminal device and at least one network device. For example, the terminal device may communicate with the network device. For example, the network device may be a base station or other communication entity that provides positioning and communication services to the terminal device. In this embodiment of the present application, the terminal device may report a plurality of capability information to the network device. In this embodiment of the present application, the terminal device transmits first capability information to the network device, the first capability information indicating that the terminal device supports transmission and / or reception of the first information by using at most a first amount of resources, the first information including a reference signal. The terminal device transmits second capability information to the network device, the second capability information indicating that the terminal device supports transmission and / or reception of the second information by using at most a second amount of resources, the second information including at least one of data or control information.

This avoids the terminal device from transmitting and / or receiving the second information by using the first amount of resources, which reduces the complexity of the terminal device and reduces the power consumption overhead of the terminal device.

[0172] This embodiment of the present application relates to communication between a terminal device and at least one network device. For example, the terminal device may communicate with two network devices. For example, the terminal device communicates with a first network device and a second network device separately. The first network device and the second network device are two different network devices. For example, the first network device is a positioning server, and the positioning server may provide a positioning service to the terminal device. The second network device may be a base station, and the base station may provide a communication service to the terminal device. In this embodiment of the present application, the first network device and the second network device may alternatively be the same network device. For example, the network device may be a base station. In the subsequent embodiments, an example in which the terminal device communicates with the first network device and the second network device separately is used for explanation.

[0173] This embodiment of the present application relates to the transmission and / or reception of the first information and the transmission and / or reception of the second information. Specifically, a number of application scenarios are included. For example, a terminal device transmits the first information and the second information. For example, a terminal device transmits the first information and receives the second information. For example, a terminal device receives the first information and transmits the second information. For example, a terminal device receives the first information and receives the second information. In this embodiment of the present application, the transmission and / or reception of the first information and the transmission and / or reception of the second information are not limited. In the subsequent embodiments, the transmission of the first information and the transmission of the second information are used as an example for explanation.

[0174] Figure 1 is a schematic flowchart of the interaction between a network device and a terminal device according to an embodiment of the present application. In the interaction procedure, step 101 to step 104 are described from the terminal device side, step 111 and step 113 are described from the first network device side, and step 112 and step 114 are described from the second network device side. The interaction procedure shown in Figure 1 mainly includes the following steps:

[0175] 101: A terminal device transmits first capability information to a first network device, the first capability information indicating that the terminal device supports transmitting and / or receiving the first information by using at most a first amount of resources, and the first information includes a reference signal.

[0176] In this embodiment of the present application, the terminal device transmits and / or receives information by using resources. The terminal device requests the network device to allocate resources. The terminal device reports capability information of the terminal device. The network device allocates resources to the terminal device based on the capability information of the terminal device.

[0177] Specifically, the terminal device transmits and / or receives the first information by using resources. The terminal device requests the network device to allocate resources. The terminal device reports first capability information of the terminal device to the first network device. The first capability information indicates that the terminal device supports the transmission and / or reception of the first information by using at most a first amount of resources, and the first information includes a reference signal. In this embodiment of the present application, the reference signal may be an uplink reference signal. For example, the uplink reference signal may be a sounding reference signal (SRS). In another example, the reference signal may alternatively be a downlink reference signal. For example, the downlink reference signal may be a positioning reference signal (PRS). It should be noted that in addition to the reference signal, the first information may further include other types of information. For example, the first information may be a control signal applicable to a specific scenario.

[0178] The terminal device generates first capability information, and the first capability information indicates that the terminal device supports the transmission and / or reception of the first information by using at most a first amount of resources. The at most a first amount of resources supported by the terminal device is a maximum amount of resources supported by the terminal device for transmitting and / or receiving the first information. For example, the maximum amount of resources supported by the terminal device is a first amount. In other words, the maximum capability of the terminal device is to transmit and / or receive the first information by using a first amount of resources, and the terminal device cannot transmit and / or receive the first information by using more than the first amount of resources.

[0179] In some implementations of this embodiment of the present application, it should be noted that the quantity in this embodiment of the present application can be understood as a number or amount. In this case, the first quantity of resources is a first number of resources. For example, when the resources are resource blocks (RB), the first quantity of resources is a first number of resource blocks. For example, when the subcarrier spacing is 120 kHz (for example, frequency range FR2), the first quantity of bandwidth is 66 resource blocks (or 132 resource blocks, or 264 resource blocks).

[0180] In some other implementations of this embodiment of the present application, it should be noted that the quantity in this embodiment of the present application may alternatively be understood as a size. In this case, the first quantity of resources is a first size of resources. For example, if the resource is a bandwidth, the first quantity of resources is a first size of bandwidth. For example, the first quantity of bandwidth is 100MHz, 200MHz, or 300MHz.

[0181] 111: A first network device receives first capability information transmitted by a terminal device, the first capability information indicating that the terminal device supports transmission and / or reception of the first information by using at most a first amount of resources, and the first information includes a reference signal.

[0182] The terminal device establishes a communication connection to a first network device. The terminal device transmits first capability information to the first network device. In this case, the first network device receives the first capability information transmitted by the terminal device. The first network device parses the first capability information. Since the first capability information indicates that the terminal device supports transmission and / or reception of the first information by using at most a first amount of resources, the first network device can obtain a maximum resource that can be used by the terminal device to transmit and / or receive the first information.

[0183] Optionally, in this embodiment of the present application, the first information includes a reference signal. For example, the reference signal is an uplink reference signal. For example, the uplink reference signal is a sounding reference signal (SRS) or an uplink positioning sounding reference signal (pos-SRS). For example, the reference signal is a downlink reference signal. For example, the downlink reference signal is a downlink positioning reference signal (PRS), a channel state information-reference signal (CSI-RS), or a synchronization signal and physical broadcast channel block (SSB). The positioning sounding reference signal pos-SRS or the sounding reference signal SRS is used by a peer device (communicating with the terminal device) to position the terminal device. The sounding reference signal SRS can be further used by a peer device performing communication to perform channel measurement.

[0184] 102: The terminal device sends second capability information to a second network device, the second capability information indicating that the terminal device supports transmitting and / or receiving second information by using up to a second amount of resources, and the second information includes at least one of data or control information.

[0185] The terminal device transmits and / or receives information by using the resource. The terminal device requests the network device to allocate the resource. The terminal device reports the capability information of the terminal device. The network device allocates the resource to the terminal device based on the capability information of the terminal device.

[0186] Specifically, the terminal device transmits and / or receives the second information by using resources. The terminal device requests the network device to allocate resources. The terminal device reports second capability information of the terminal device to the second network device. The second capability information indicates that the terminal device supports the transmission and / or reception of the second information by using at most a second amount of resources. The second information includes at least one of data or control information. The data may be data carried on a physical shared channel. The control information may be control information carried on a physical control channel.

[0187] Optionally, in this embodiment of the present application, the second information includes at least one type of data or control information. For example, the second information is data carried on a physical shared channel. The physical shared channel may be a physical downlink shared channel or a physical uplink shared channel. The control information may be information carried on a physical control channel. The physical control channel may be a physical uplink control channel and / or a physical downlink control channel. Furthermore, in some implementations of this embodiment of the present application, the second information may further include a sounding reference signal.

[0188] For example, the first information is a positioning sounding reference signal, and the second information is data. For example, the first information is a positioning sounding reference signal, and the second information is data or a sounding reference signal.

[0189] In some embodiments of the present application, the second information does not include a reference signal. In this embodiment of the present application, for different types of information, the terminal device separately reports capability information corresponding to the information. The terminal device may be classified into two types based on whether the information is a reference signal. For example, the first information includes a reference signal, and the second information does not include a reference signal. In this case, the terminal device may separately report the first capability information corresponding to the first information and the second capability information corresponding to the second information for the first information and the second information.

[0190] Additionally, it should be noted that reference signals are distinct from data, and reference signals are distinct from control information.

[0191] It should be noted that the order of step 101 and step 102 is not limited in the present application. In addition, the generation of the first capability information does not depend on the generation of the second capability information. Similarly, the generation of the second capability information does not depend on the generation of the first capability information. As an illustrative example, in FIG. 1, an example in which step 101 is performed first and then step 102 is performed is used for explanation, but this is not intended to limit this embodiment of the present application.

[0192] In some implementations of this embodiment of the present application, it should be noted that the quantity in this embodiment of the present application can be understood as a number or amount. In this case, the first quantity of resources is a first number of resources, and the second quantity of resources is a second number of resources. For example, when the resources are resource blocks, the first quantity of resources is a first number of resource blocks, and the second quantity of resources is a second number of resource blocks. For example, when the subcarrier spacing is 30 kHz (frequency range FR1), the bandwidth of the second quantity is 51 resource blocks (or 106 resource blocks, or 11 resource blocks). For example, when the subcarrier spacing is 120 kHz (frequency range FR2), the bandwidth of the first quantity is 66 resource blocks (or 132 resource blocks, or 264 resource blocks).

[0193] In some implementations of this embodiment of the present application, it should be noted that the quantity in this embodiment of the present application may alternatively be understood as a size. In this case, the first quantity of resources is a first size of resources, and the second quantity of resources is a second size of resources. For example, if the resource is a bandwidth, the first quantity of resources is a first size of bandwidth, and the second quantity of resources is a second size of bandwidth. For example, the second quantity of bandwidth is 20MHz, 40MHz, or 5MHz. For example, the first quantity of bandwidth is 100MHz, 200MHz, or 300MHz.

[0194] The following describes the first capability information and the second capability information. The first capability information indicates that the terminal device supports the transmission of the first information by using at most a first amount of resources. In other words, the first capability information indicates a first quantity, and the first amount of resources is the maximum bandwidth supported by the terminal device to transmit the first information.

[0195] The second capability information indicates that the terminal device supports the transmission of the second information by using at most a second amount of resources. In other words, the second capability information indicates a second quantity, and the second amount of resources is a maximum bandwidth supported by the terminal device (for transmitting the second information).

[0196] 112: A second network device receives second capability information transmitted by the terminal device, the second capability information indicating that the terminal device supports transmission and / or reception of second information by using up to a second amount of resources, and the second information includes at least one of data or control information.

[0197] A communication connection is established between the terminal device and the second network device, and the terminal device transmits second capability information to the second network device. In this case, the second network device receives the second capability information transmitted by the terminal device, and the second network device parses the second capability information. Since the second capability information indicates that the terminal device supports transmitting and / or receiving the second information by using at most a second amount of resources, the second network device can obtain the maximum resources that can be used by the terminal device to transmit and / or receive the second information.

[0198] It should be noted that the order of steps 111 and 112 is not limited in this application.

[0199] 113: The first network device sends first configuration information to the terminal device, optionally, the first configuration information indicating that a quantity of resources configured for the first information is less than or equal to a first quantity.

[0200] In this embodiment of the present application, the first network device may determine the first configuration information based on the first information. Specifically, the first network device performs the aforementioned step 111. The first network device obtains the first capability information sent by the terminal device, and the first network device parses the first capability information. Since the first capability information indicates that the terminal device supports the transmission and / or reception of the first information by using at most a first amount of resources, the first network device may obtain the maximum resources that can be used by the terminal device to transmit and / or receive the first information. The first network device may configure resources for the first information. For example, the first network device configures resources used by the terminal device to transmit and / or receive the first information. The first network device generates the first configuration information. The first configuration information indicates that the amount of resources configured for the first information is equal to or less than a first quantity. The first amount is obtained by parsing the first capability information by the first network device, or is obtained based on an indication of the first capability information.

[0201] For example, the first configuration information may be included in one or more of radio resource control (RRC), medium access control (MAC) signaling, and downlink control information (DCI), or the first configuration information may be included in signaling sent by the positioning service device to the terminal device. For example, the positioning service device is the first network device.

[0202] It should be particularly noted that in some implementations of this embodiment of the present application, the first configuration information indicates a manner of transmitting and / or receiving the first information. Manner of the first information: The first information is transmitted and / or received based on the bandwidth of the terminal device (i.e., the bandwidth of the second quantity). Alternatively, manner of the first information: The first information is transmitted and / or received based on the bandwidth of the first quantity.

[0203] Transmitting and / or receiving the first information based on the bandwidth of the terminal device may be understood as transmitting and / or receiving the first information by the terminal device based on a mechanism specified for the first type of terminal device according to the standard. The bandwidth of the first type of terminal device is equal to the bandwidth of the second quantity. For example, the first type of terminal device may be a reduced capability device. For example, the bandwidth of the second quantity may be 5 MHz or 20 MHz.

[0204] Transmitting and / or receiving the first information based on the bandwidth of the first quantity may be understood as transmitting and / or receiving the first information by the terminal device based on a mechanism specified for the second type of terminal device according to the standard. The bandwidth of the second type of terminal device is larger than the bandwidth of the first type of terminal device. For example, the second type of terminal device may be an advanced mobile broadband device. For example, the bandwidth of the first quantity may be 5 MHz, 20 MHz, 40 MHz, or 100 MHz.

[0205] In some embodiments of the present application, the first configuration information configured by the first network device does not exceed the first capability information reported by the terminal device. For example, the bandwidth of the positioning sounding reference signal reported by the terminal device is 100 MHz, and the transmission bandwidth of the positioning sounding reference signal configured by the first network device does not exceed 100 MHz. For example, the transmission bandwidth of the positioning sounding reference signal configured by the first network device is 20 MHz, 40 MHz, 80 MHz, or 100 MHz.

[0206] 103: The terminal device obtains first configuration information, and optionally, the first configuration information indicates that a quantity of resources configured for the first information is less than or equal to a first quantity.

[0207] In this embodiment of the present application, after the terminal device reports the first capability information, the terminal device may obtain first configuration information, where the first configuration information indicates a resource configuration for transmitting and / or receiving the first information. The first configuration information includes a resource indication configured for the first information. For example, if the first configuration information indicates a quantity of resources configured for the first information, the quantity of resources configured for the first information is equal to or less than the first quantity. In other words, the terminal device knows that the quantity of resources configured for the first information is equal to or less than the first quantity.

[0208] For example, a terminal device may obtain first configuration information from a first network device such that the terminal device knows that the quantity of resources configured for the first information is less than or equal to a first quantity.

[0209] 114: The second network device sends second configuration information to the terminal device, optionally, the second configuration information indicating that a quantity of resources configured for the second information is less than or equal to a second quantity.

[0210] In this embodiment of the present application, the second network device may determine the second configuration information based on the second information. Specifically, the second network device performs the aforementioned step 112. The second network device obtains the second capability information transmitted by the terminal device. The second network device parses the second capability information. Since the second capability information indicates that the terminal device supports the transmission and / or reception of the second information by using at most a second amount of resources, the second network device may obtain the maximum resources that can be used by the terminal device to transmit and / or receive the second information. The second network device may configure resources for the second information. For example, the second network device configures resources used by the terminal device to transmit and / or receive the second information. The second network device generates the second configuration information. The second configuration information indicates that the amount of resources configured for the second information is equal to or less than a second amount. The second amount is obtained by the second network device by parsing the second capability information or is obtained based on an indication of the second capability information.

[0211] For example, the second configuration information may be one or more of RRC signaling, MAC signaling, and DCI, or the second configuration information may be included in a signaling sent by the positioning service device to the terminal device. For example, the positioning service device is a second network device. The configuration in this embodiment of the present application may be understood as allocation or scheduling.

[0212] 104: The terminal device acquires second configuration information, optionally, the second configuration information indicating that a quantity of resources configured for the second information is less than or equal to a second quantity.

[0213] In this embodiment of the present application, after the terminal device reports the second capability information, the terminal device may obtain second configuration information, where the second configuration information indicates a resource configuration for transmitting and / or receiving the second information. The second configuration information includes a resource indication configured for the second information. For example, if the second configuration information indicates a quantity of resources configured for the second information, the quantity of resources configured for the second information is equal to or less than the second quantity. In other words, the terminal device knows that the quantity of resources configured for the second information is equal to or less than the second quantity.

[0214] Note that the order of 103 and 104 is not critical, and the order of 113 and 114 is not critical.

[0215] For example, the terminal device may obtain second configuration information from a second network device such that the terminal device knows that the quantity of resources configured for the second information is less than or equal to a second quantity.

[0216] In some embodiments of the present application, the first quantity is greater than the second quantity.

[0217] The first quantity is the quantity of resources indicated by the first capability information, and the second quantity is the quantity of resources indicated by the second capability information. The first capability information is used to request resources corresponding to the first information (e.g., the first information is a reference signal), and the second capability information is used to request resources corresponding to the second information (e.g., the second information is data or control information). In this case, the first quantity is greater than the second quantity. In other words, the terminal device may request a large amount of resources for transmitting a reference signal and a small amount of resources for transmitting data. Thus, the high-precision positioning requirements of the terminal device (e.g., RedCap UE) may be implemented without significantly increasing the complexity / cost / power consumption of the UE.

[0218] In this embodiment of the present application, increasing the radio frequency bandwidth does not significantly increase the cost of the UE, but the cost of the UE increases significantly with the bandwidth capability (i.e., baseband bandwidth) of the UE's data transmission (hereinafter simply referred to as data transmission). Therefore, in this embodiment of the present application, the positioning performance is improved and a significant increase in the complexity / cost of the UE is effectively avoided.

[0219] In some embodiments of the present application, the first quantity belongs to a first set of quantities, and at least one quantity in the first set of quantities is greater than the second quantity, or The first quantity belongs to a first set of quantities, the second quantity is predefined, and at least one quantity in the first set of quantities is greater than the second quantity; the first quantity belongs to a first set of quantities and the second quantity belongs to a second set of quantities, and at least one quantity in the first set of quantities is greater than the second quantity; or the first quantity belongs to a first set of quantities and the second quantity belongs to a second set of quantities, and at least one quantity in the first set of quantities is greater than all quantities in the second set of quantities; or the first quantity is predefined and the second quantity is predefined, the first quantity being greater than the second quantity; or The first quantity is predefined and the second quantity is predefined, the first quantity being less than or equal to the second quantity.

[0220] However, the first quantity and the second quantity are determined separately by the terminal device. For example, the first quantity belongs to a first set of quantities, and at least one quantity in the first set of quantities is greater than the second quantity. The implementation form of the first set of quantities is not limited in this embodiment of the application. For example, the first set of quantities may include one component or may include multiple components, and the components are the quantities that constitute the first set of quantities. At least one quantity in the first set of quantities is greater than the second quantity. Thus, the first quantity may be greater than the second quantity. The specific value of the first quantity is not limited in this specification.

[0221] For example, the first quantity belongs to a first set of quantities, the second quantity is predefined, and at least one quantity in the first set of quantities is greater than the second quantity, and the second quantity is predefined by the terminal device. For example, the terminal device predefines that the bandwidth of the second quantity is 20MHz, 40MHz, or 5MHz, or predefines that the bandwidth of the second quantity is 51 resource blocks (or 106 resource blocks, or 11 resource blocks). The first set of quantities may include one component or may include multiple components, and the components are quantities that constitute the first set of quantities. At least one quantity in the first set of quantities is greater than the second quantity. Thus, the first quantity may be greater than the second quantity. The specific value of the first quantity is not limited in this specification.

[0222] For example, the first quantity belongs to a first set of quantities, the second quantity belongs to a second set of quantities, and at least one quantity in the first set of quantities is greater than the second quantity. In this embodiment of the present application, the implementation of the first set of quantities and the second set of quantities is not limited. For example, the first set of quantities may include one component or may include multiple components, and the components are the quantities that make up the first set of quantities. The second set of quantities may include one component or may include multiple components, and the components are the quantities that make up the second set of quantities. At least one quantity in the first set of quantities is greater than the second quantity. Thus, the first quantity may be greater than the second quantity. The specific value of the first quantity is not limited herein.

[0223] For example, the first quantity belongs to a first set of quantities, the second quantity belongs to a second set of quantities, and at least one quantity in the first set of quantities is greater than all quantities in the second set of quantities. In this embodiment of the present application, the implementation of the first set of quantities and the second set of quantities is not limited. For example, the first set of quantities may include one component or may include multiple components, and the components are the quantities that make up the first set of quantities. The second set of quantities may include one component or may include multiple components, and the components are the quantities that make up the second set of quantities. At least one quantity in the first set of quantities is greater than all quantities in the second set of quantities. Thus, the first quantity may be greater than the second quantity. The specific value of the first quantity is not limited herein.

[0224] For example, the first quantity is predefined and the second quantity is predefined, the first quantity being greater than the second quantity.

[0225] For example, the first quantity is predefined and the second quantity is predefined, the first quantity being less than or equal to the second quantity.

[0226] In this embodiment of the present application, the specific values ​​of the first quantity and the second quantity may be predefined. The terminal device may indicate whether the first quantity is valid by using the first capability information. In addition, the terminal device may indicate whether the second quantity is valid by using the second capability information. It should be noted that the terminal device may configure the first capability information and the second capability information separately. If the first quantity is greater than the second quantity, the high-precision positioning requirements of the terminal device (e.g., RedCap UE) may be implemented without significantly increasing the complexity / cost / power consumption of the UE. If the first quantity is equal to or less than the second quantity, the transmission bandwidth capability of the positioning reference signal may be less than the bandwidth capability of the data transmission, and the positioning reference signal may not be transmitted in the full bandwidth. This can effectively reduce the power consumption of the UE.

[0227] In some embodiments of the present application, the resource is one or more of a bandwidth, a resource block, a carrier, a subband, a frequency range, a frequency segment, a frequency band, a subcarrier spacing, a bandwidth part (BWP), a frequency hopping interval, and a number of frequency hops in a particular time range. The resource defined in this embodiment of the present application has multiple implementation forms. For example, the resource may be a bandwidth, or the resource may be a resource block. This is not limited in this embodiment of the present application. The related concepts of the bandwidth, the resource block, the carrier, the subband, the frequency range, the frequency segment, the frequency band, the subcarrier spacing, the BWP, the frequency hopping interval, and the number of frequency hops in a particular time range are not described again in this specification.

[0228] In some embodiments of the present application, optionally, in addition to the steps mentioned above, the communication method provided in this embodiment of the present application further includes the following steps:

[0229] A1: The terminal device sends third capability information to the first network device or the second network device.

[0230] A2: The first network device or the second network device receives the third capability information sent by the terminal device.

[0231] The third capability information is Whether the terminal device supports transmitting and / or receiving the first information in a carrier aggregation manner; and / or The terminal device supports transmission and / or reception of the first information by using up to M carriers, where M is a positive integer. Shows.

[0232] The third capability information may be transmitted by the terminal device by using RRC signaling. The third capability information and the first capability information may be transmitted by the same signaling, or may be transmitted separately by using different signaling from the third capability information and the first capability information. This is not limited in this specification. In addition, the third capability information and the second capability information may be transmitted by the same signaling, or may be transmitted separately by using different signaling from the third capability information and the second capability information. This is not limited in this specification. The specific implementation form of the third capability information depends on the application scenario and is not limited in this specification.

[0233] In this embodiment of the present application, the third capability information indicates whether the terminal device supports the transmission and / or reception of the first information in a carrier aggregation manner. For example, the third capability information may be 1-bit indication information, and the indication information indicates whether the terminal device supports the transmission and / or reception of the first information in a carrier aggregation manner. In addition, the third capability information indicates that the terminal device supports the transmission and / or reception of the first information by using at most M carriers, where M is a positive integer. For example, the value of M may be carried in the third capability information. The terminal device transmits and / or receives the first information by using at most M carriers means that the maximum number of carriers used by the terminal device may be M carriers. Since the terminal device transmits the third capability information, the first network device or the second network device may determine whether the terminal device uses carrier aggregation and determine the number of carriers used for aggregation.

[0234] The following describes carrier aggregation. In some implementations of this embodiment of the present application, the terminal device may transmit the first information on a larger frequency resource through frequency hopping, carrier switching, carrier aggregation, combined frequency hopping and carrier switching, or combined frequency hopping and carrier aggregation. For example, the terminal device may transmit a positioning reference signal on a resource corresponding to a single carrier of up to 100 MHz to implement higher accuracy positioning.

[0235] For example, when different carriers overlap, the terminal device may transmit a positioning sounding reference signal on a larger frequency resource through carrier (CC) switching. According to such a method, the terminal device does not need to be able to transmit a positioning sounding reference signal in a carrier aggregation manner. This reduces the complexity of the UE. As shown in FIG. 2a, there are three carriers CC1, CC2, and CC3, each carrier is 100 MHz, and it is assumed that different carriers overlap. According to the method of joint frequency hopping and carrier switching, the UE may transmit a positioning sounding reference signal on a frequency resource of nearly 300 MHz to maintain low complexity of the terminal device. In other words, the UE does not need to have the ability to transmit a positioning sounding reference signal in a carrier aggregation manner, and can further implement higher-precision positioning.

[0236] As another example, when different carriers do not overlap, the terminal device may transmit a positioning sounding reference signal with a larger frequency resource through joint frequency hopping and carrier aggregation. As shown in FIG. 2b, it is assumed that there are three carriers, CC1, CC2, and CC3. CC2 overlaps with CC1 and CC3. It is assumed that each carrier is 100 MHz, and different carriers do not overlap. Therefore, carrier aggregation needs to be performed. For example, the UE may transmit a positioning sounding reference signal with a frequency resource of approximately 300 MHz according to the method of joint frequency hopping and carrier aggregation to implement a higher accuracy of positioning.

[0237] In some embodiments of the present application, optionally, in addition to the steps mentioned above, the communication method provided in this embodiment of the present application further includes the following steps:

[0238] B1: The terminal device sends fourth capability information to the first network device or the second network device.

[0239] B2: The first network device or the second network device receives the fourth capability information sent by the terminal device.

[0240] The fourth capability information is The terminal device does not support the transmission and / or reception of the second information in a carrier aggregation manner; or The terminal device supports transmission and / or reception of the second information by using up to N carriers, where N is a positive integer. Shows.

[0241] The fourth capability information may be transmitted by the terminal device by using RRC signaling. The fourth capability information and the first capability information may be transmitted by the same signaling, or may be transmitted separately by using a signaling different from the fourth capability information and the first capability information. This is not limited in this specification. In addition, the fourth capability information and the second capability information may be transmitted by the same signaling, or may be transmitted separately by using a signaling different from the fourth capability information and the second capability information. This is not limited in this specification. The specific implementation form of the fourth capability information depends on the application scenario and is not limited in this specification.

[0242] In this embodiment of the present application, the fourth capability information indicates whether the terminal device supports the transmission and / or reception of the second information in a carrier aggregation manner. For example, the fourth capability information may be 1-bit indication information, and the indication information indicates that the terminal device does not support the transmission and / or reception of the second information in a carrier aggregation manner. In addition, the fourth capability information indicates that the terminal device supports the transmission and / or reception of the second information by using at most N carriers, where N is a positive integer. For example, the value of N may be carried in the fourth capability information. The terminal device transmitting and / or receiving the second information by using at most N carriers means that the maximum number of carriers used by the terminal device may be N carriers. Because the terminal device transmits the fourth capability information, the first network device or the second network device may determine that the terminal device does not use carrier aggregation and determine the number of carriers used for aggregation.

[0243] Further, in some embodiments of the present application, N is less than M, or N is less than or equal to M.

[0244] When N is less than M, the high-precision positioning requirements of a terminal device (e.g., RedCap UE) can be implemented without significantly increasing the complexity / cost / power consumption of the UE. N being less than or equal to M means that N is less than M or N=M. When N is less than M, the high-precision positioning requirements of a terminal device (e.g., RedCap UE) can be implemented without significantly increasing the complexity / cost / power consumption of the UE. When N=M, the transmission bandwidth capability of the positioning reference signal is equal to the bandwidth capability of data transmission. This simplifies the configuration scheme of the transmission bandwidth of the positioning reference signal and the bandwidth of data transmission.

[0245] In some embodiments of the present application, optionally, in addition to the steps mentioned above, the communication method provided in this embodiment of the present application further includes the following steps:

[0246] C1: The terminal device sends fifth capability information to the first network device or the second network device.

[0247] C2: The first network device or the second network device receives the fifth capability information sent by the terminal device.

[0248] The fifth capability information is the terminal device supports generation of the first information according to the first algorithm; the terminal device supports generation of the first information according to a second algorithm; or The terminal device supports generation of the first information according to the first algorithm and the second algorithm. Shows.

[0249] The first algorithm and the second algorithm are different algorithms.

[0250] The fifth capability information may be transmitted by the terminal device by using RRC signaling. The fifth capability information and the first capability information may be transmitted by the same signaling, or may be transmitted separately by using different signaling from the fifth capability information and the first capability information. This is not limited in this specification. In addition, the fifth capability information and the second capability information may be transmitted by the same signaling, or may be transmitted separately by using different signaling from the fifth capability information and the second capability information. This is not limited in this specification. The specific implementation form of the fifth capability information depends on the application scenario and is not limited in this specification.

[0251] The algorithm in this embodiment of the present application may be a sequence generation method. The contents or quantities of sequences generated by different algorithms are not completely the same. For example, the sequence ID used when the first algorithm generates a sequence is in the range of {0, ..., 1023}. For example, the sequence ID used when the second algorithm generates a sequence is in the range of {0, ..., 65535}.

[0252] In some embodiments of the present application, optionally, in addition to the steps mentioned above, the communication method provided in this embodiment of the present application further includes the following steps:

[0253] D1: The terminal device sends sixth capability information to the first network device or the second network device.

[0254] D2: The first network device or the second network device receives the sixth capability information sent by the terminal device.

[0255] The sixth capability information includes at least one type of information: scrambling code information, location information, period information, spacing information, frequency hopping information, density information, reserved time information, tuning time information, non-simultaneous transmission information, and non-simultaneous reception information.

[0256] The scrambling code information includes at least one of a scrambling code range and a scrambling code value set.

[0257] The location information is a location where the first information is transmitted and / or received and can be supported by the terminal device.

[0314] From the exemplary description of the foregoing embodiment, it can be seen that the terminal device may establish a communication connection to at least one network device. For example, the terminal device may establish a communication connection to a first network device and a second network device separately, and the terminal device may report different capability information to the at least one network device separately, so that the terminal device reports multiple capability information to the network device. In other words, the terminal device may independently report different capability information to one network device, or the terminal device reports different capability information to different network devices separately.

In this embodiment of the present application, the terminal device may report that the terminal device supports the transmission and / or reception of a reference signal by using at most a first amount of resources by using the first capability information, and the terminal device may report that the terminal device supports the transmission and / or reception of the second information by using at most a second amount of resources by using the second capability information, so that the terminal device independently reports information regarding the capability of transmitting and / or receiving a reference signal. This solves the communication problem of the terminal device supporting the transmission and / or reception of a reference signal.

[0315] The following describes detailed application scenarios.

[0316] This embodiment of the present application may be applied to implement high precision positioning requirements of a terminal device (eg, RedCap UE) without significantly increasing the complexity / cost / power consumption of the UE.

[0317] In this embodiment of the present application, the UE determines the maximum resource (referred to as the "first resource") that can be used by the UE to transmit a positioning reference signal, and the UE determines the maximum resource (referred to as the "second resource") for data transmission (hereinafter simply referred to as data transmission). The UE is a new form of UE that is different from a normal UE. In order to implement high-precision positioning and low complexity, the first resource may be larger than the second resource. For example, the "transmission bandwidth capability of the positioning reference signal" is not limited to the "bandwidth capability of data transmission", and is configured such that the carrier aggregation (CA) capability of the positioning reference signal and the CA capability of the data transmission are different. Details are provided below.

[0318] (1) The "positioning reference signal transmission bandwidth capability" may be greater than the "data transmission bandwidth capability". For example, the data transmission bandwidth capability of a RedCap UE is 20 MHz, and the positioning reference signal transmission bandwidth capability of the RedCap UE may be 40 MHz, 60 MHz, 80 MHz, or 100 MHz, and the "positioning reference signal transmission bandwidth capability" may be less than or equal to the "data transmission bandwidth capability".

[0319] (2) If the uplink positioning reference signal supports CA, the UE's data transmission (uplink transmission or downlink reception) may not support CA.

[0320] This embodiment of the present application is applied to a 5G positioning scenario, and related network elements include an LMF, a base station (such as a gNB / ng-eNB), and a UE.

[0321] This embodiment of the present application is applied to a 5G positioning scenario, and the functions of the network elements include:

[0322] (1) The LMF sends an LTE Positioning Protocol (LPP) message to the UE, and the UE completes corresponding operations according to the instructions of the LPP message and reports position measurement information to the LMF accordingly. The network elements involved in this procedure include the LMF and the UE.

[0323] (2) The gNB / ng-eNB sends a radio resource control (RRC) message or a MAC control element (CE) to the UE, and the UE completes the corresponding operation according to the instruction of the RRC message or the MAC CE, and reports an acknowledgment message to the gNB / ng-eNB accordingly. Related network elements include the gNB / ng-eNB and the UE.

[0324] The interaction between the UE and the network unit in this embodiment of the present application is described from the UE side first.

[0325] The UE reports the (maximum) resource capability information of the UE's uplink positioning reference signal to the network unit (LMF / base station / other communication entity). The UE reports the (maximum) resource capability information of the UE's data transmission to the network unit. The UE may obtain the configuration information of the uplink positioning reference signal from the network unit. The UE transmits the SRS based on the configuration information of the positioning reference signal received from the network unit.

[0326] The (maximum) resource capability of the uplink positioning reference signal reported by the UE may be greater (or higher) than the (maximum) resource capability of the data transmission. Of course, the (maximum) resource capability of the uplink positioning reference signal reported by the UE may alternatively be less than or equal to the (maximum) resource capability of the data transmission.

[0327] The following provides a description from the network unit (LMF / base station / other communication entity) side.

[0328] The network unit may obtain from the UE (maximum) resource capability information of the UE's uplink positioning reference signal.

[0329] The network unit may obtain from the UE (maximum) resource capability information for data transmission of the UE.

[0330] The network unit may obtain configuration information of the UE's uplink positioning reference signal from the UE.

[0331] The network unit may receive a sounding reference signal SRS transmitted by the UE based on the reference signal configuration information.

[0332] In the 5G core network based positioning architecture, the LMF is responsible for supporting different types of location services related to the target UE, including UE positioning and forwarding assistance data to the UE. The control plane and user plane of the LMF are the Enhanced Serving Mobile Location Centre (E-SMLC) and the Secure User Plane Location (SUPL) Location Platform (SLP), respectively. The LMF may exchange information with the ng-eNB / gNB and the UE.

[0333] The information exchange may be information exchange between the LMF and the ng-eNB / gNB by using an NRPPa (NR Positioning Protocol Annex) message, such as obtaining PRS configuration information, SRS configuration information, cell timing information, and cell location information. NRPPa is a signaling protocol between the LMF and the base station in the 5G system. The NRPPa message is a message carrier for signaling / information exchange between the LMF and the base station.

[0334] In addition, the information exchange may be UE capability information transfer, auxiliary information transfer, measurement information transfer, etc., with the UE by using LTE Positioning Protocol (LPP) messages, and may be information used to assist the user in measurements or position calculations.

[0335] In a positioning architecture based on a 5G core network, an Access and Mobility Management Function (AMF) may receive a location service request related to a target UE from a Location Services (LCS) entity, and the AMF may initiate some location services on behalf of a specific target UE and forward the location service request to the LMF. After receiving the location information returned by the UE, the AMF returns the related location information to the LCS entity. The LCS is a management module for exchanging location traffic between the core network and outside the core network.

[0336] In a positioning architecture based on a 5G core network, the gNB / ng-eNB may provide measurement information for the target UE and forward the information to the LMF.

[0337] The following describes the application scenario in the embodiments of this application by using two embodiments. The embodiment 1 is described from the UE side, and the embodiment 2 is described from the network device side. As shown in Fig. 3a, step S01 and step S02 are performed by the UE, and step S03 and step S04 are performed by the network device.

[0338] EMBODIMENT 1 In order to improve positioning accuracy, the UE may transmit a positioning reference signal on more (or larger) resources. However, in order to avoid a significant increase in the cost of the UE, the UE may only communicate with peer devices or perform data transmission on fewer (or smaller) resources. In other words, the resources that can be used by the UE to transmit a positioning reference signal may be larger than the maximum resources that can be used when the UE communicates with peer devices or performs data transmission.

[0339] Since the UE can communicate with peer devices or perform data transmission only on fewer (or smaller) resources, the complexity of the baseband processing capability of the UE is low. For example, the baseband processing may include data processing, control channel processing, channel estimation, channel measurement, multi-antenna signal processing, etc. For example, the data processing may include receiving, decoding, detecting downlink data, and generating, encoding, shaping uplink data. However, since the UE may transmit positioning reference signals on more (or larger) resources, when the UE has high-precision positioning capability, the maximum baseband processing capability of the UE does not match (e.g., is the same or equivalent to) the maximum resource supported by the UE's uplink positioning reference signal, so the UE can implement low complexity or low cost. In addition, the UE can communicate with peer devices or perform data transmission only on fewer (or smaller) resources, and the power consumption overhead of the UE is reduced. This implements low power consumption.

[0340] It should be noted that the resource may be one or more of a bandwidth, a subband, a resource including one or more resource blocks, one or more carrier resources, a frequency range, a frequency segment, a frequency band, one or more subcarrier spacings, a number of subcarrier spacings, a bandwidth portion BWP, a frequency hopping interval, and a number of frequency hops.

[0341] Therefore, in this embodiment of the present application, in this embodiment of the present application, the UE determines the maximum resource (called "first resource") that can be used by the UE to transmit a positioning reference signal, and the UE determines the maximum resource (called "second resource") for data transmission. The UE is a new form of UE that is different from a normal UE. In order to implement high-precision positioning and low complexity, the first resource may be larger than the second resource. Figure 3b is a schematic diagram in which the first resource of the UE is 100 MHz and the second resource of the UE is 20 MHz.

[0342] Specifically, the UE may report to the LMF or the base station (or other communication entity) the (maximum) resource capability information of the UE's uplink positioning reference signal. The following describes important features of the first embodiment.

[0343] Step S01: The UE reports (maximum) resource capability information of the UE's uplink positioning reference signal to the LMF or base station (or other communication entity).

[0344] For example, the resource capability information of the uplink positioning reference signal includes one or more of the following: the maximum bandwidth that can be occupied when the UE transmits the positioning reference signal on a single carrier, whether the UE supports carrier aggregation CA of the uplink positioning reference signal, the number of carriers for which CA can be supported by the UE, the maximum bandwidth after the UE supports the positioning reference signal CA, the tuning time of the UE, etc. The frequency hopping position scenario is mainly considered. During the next frequency hop, the center frequency of the carrier needs to be adjusted. Therefore, a certain hardware adjustment time, called "tuning time", is required.

[0345] For example, the resource capability information of the uplink positioning reference signal may indicate that the UE supports generation of sequences based on Type 1, or that the UE supports generation of SRS sequences based on Type 2. Alternatively, the resource capability information of the uplink positioning reference signal may further indicate that the UE supports generation of sequences based on Type 1, or that the UE supports generation of sequences based on Type 2, or that the UE supports generation of sequences based on Types 1 and 2.

[0346] For example, the resource capability information of the uplink positioning reference signal may include scrambling code information used by the UE to generate the uplink positioning reference signal, The scrambling code information may be one or more of a scrambling code range and a scrambling code value set.

[0347] For example, the resource capability information of the uplink positioning reference signal may include one or more of location information, period information, spacing information, frequency hopping information, density information, reserved time information, tuning time information, non-simultaneous transmission information, and non-simultaneous reception information used by the UE to generate the uplink positioning reference signal.

[0348] The location information is for transmitting an uplink positioning reference signal and may be a location supported by the UE, such as a fixed location or a flexible location. Alternatively, the location where the UE transmits the uplink positioning reference signal is within a specific time of a synchronization signal block SSB. Since the location where the UE transmits the uplink positioning reference signal is within a specific time of the SSB, the UE can quickly perform synchronization tracking. This reduces power consumption. The UE may report a specific expected time value or range.

[0349] The period information may be a period for transmitting an uplink positioning reference signal that may be supported by the UE.

[0350] The interval information may be the (minimum) interval that may be supported by the UE between two consecutive transmissions of the uplink positioning reference signal.

[0351] The frequency hopping information may be one or more of: whether the uplink positioning reference signal of the UE supports frequency hopping, the number of hops at a particular time, the number of resource blocks RB occupied by each hop (or the frequency width occupied by the signal at each hop), the second resource width at each hop, the frequency hopping offset, the frequency resource range of the frequency hopping, and the subcarrier spacing information. At least one of the values ​​of the frequency hopping offset may allow the frequency resources of two adjacent uplink positioning reference signals to overlap. The first resource bandwidth is a bandwidth corresponding to the maximum resource that can be used by the UE to transmit the positioning reference signal. The second resource bandwidth is a bandwidth corresponding to the maximum resource for data transmission.

[0352] The density information may be the number of times that the UE transmits an uplink positioning reference signal within a particular time range.

[0353] The reserved time information may be a time length that needs to be reserved before the UE transmits an uplink positioning reference signal, or a time length that needs to be reserved after the UE transmits an uplink positioning reference signal, or a time length that needs to be reserved between two transmissions of an uplink positioning reference signal by the UE.

[0354] The tuning time information may be a switch time from an uplink positioning reference signal transmission to a next uplink positioning reference signal transmission by the UE.

[0355] The non-simultaneous transmission information may indicate that the UE does not support transmission of other uplink signals (of one or more types) when transmitting the uplink positioning reference signal.

[0356] The non-simultaneous reception information may indicate that the UE does not support reception of other downlink signals (of one or more types) when transmitting an uplink positioning reference signal.

[0357] Of course, some resource capability information of the uplink positioning reference signal of the UE may be pre-specified. In this way, the UE does not need to report pre-specified resource capability information. For example, reserved time information is pre-specified, or non-simultaneous transmission information is pre-specified, or non-simultaneous reception information is pre-specified. For example, the time that the UE needs to reserve before or after transmitting the uplink positioning reference signal is pre-specified. For example, it is pre-specified that the UE cannot transmit the physical uplink shared channel PUSCH and / or the physical uplink control channel PUCCH when transmitting the uplink positioning reference signal. For example, it is pre-specified that the UE cannot receive the PDSCH and / or the PDCCH when transmitting the uplink positioning reference signal. For example, it is pre-specified that the position where the UE transmits the uplink positioning reference signal is within n ms after the SSB. For example, n=5 or n=10.

[0358] Specifically, the resource capability of the UE is pre-specified, or the UE may further report the resource capability information of the UE to the LMF or the base station (or other communication entity). For example, the resource capability information of the UE is a (maximum) resource capability of data transmission. For example, the maximum bandwidth for the data transmission of the UE is pre-specified, or it is pre-specified that the data transmission of the UE does not support CA. For example,

[0359] Step S02: The UE reports (maximum) resource capability information of the UE's data transmission to the LMF or base station (or other communication entity).

[0360] For example, the resource capability information for data transmission includes one or more of the following: a maximum bandwidth for data transmission of the UE, a maximum baseband bandwidth for data transmission of the UE, a maximum radio frequency bandwidth for data transmission of the UE, carrier aggregation CA that the UE does not support for data transmission, a number of carriers for which CA can be supported by the UE data transmission, a maximum bandwidth after the UE data transmission supports CA of a positioning reference signal, a tuning time for data transmission of the UE, and the like.

[0361] The maximum bandwidth is the maximum bandwidth for data transmission of the UE.

[0362] The maximum baseband bandwidth and the maximum radio frequency bandwidth are explained below. First, the "baseband bandwidth" and the "radio frequency bandwidth" are explained.

[0363] The baseband bandwidth is the inherent frequency band (frequency bandwidth) of the original electrical signal transmitted by the source (information source also called the transmitting terminal) without any modulation (spectral shifting and transformation) performed on it, which is called the fundamental frequency band, or simply called baseband. The radio frequency bandwidth is the frequency band (frequency bandwidth) of the baseband signal with any modulation (spectral shifting and transformation) performed on it.

[0364] In this embodiment of the present application, maximum data transmission bandwidth=maximum baseband bandwidth≦maximum radio frequency bandwidth.

[0365] It should be noted that the (maximum) resource capability of the uplink positioning reference signal reported by the UE may be greater (or higher) than the (maximum) resource capability of the data transmission. Of course, the (maximum) resource capability of the uplink positioning reference signal reported by the UE may alternatively be less than or equal to the (maximum) resource capability of the data transmission.

[0366] FIG. 3b is a schematic diagram of a UE reporting the resource capability information of the UE's uplink positioning reference signal and the resource capability information of the UE to an LMF or a base station.

[0367] The following provides some illustrative examples.

[0368] For example, the resource capability information of the uplink positioning reference signal reported by the UE is as follows: {Bandwidth(RB):ENUMERATED{n50,n100,n200,n300,n400,…}. SCS:{15KHz,30KHz,...}. CA info}.

[0369] For example, the resource capability information of the uplink positioning reference signal reported by the UE is as follows: {Bandwidth(MHz):ENUMERATED{n10,n20,n40,n60,n100,n200,…}. SCS:{15KHz,30KHz,...}}.

[0370] For example, the bandwidth of the uplink positioning reference signal reported by the UE is 100 MHz, and the bandwidth of the UE is 20 MHz.

[0371] For example, the bandwidth of the uplink positioning reference signal reported by the UE is N RBs, and the bandwidth of the UE is M RBs, where N>M.

[0372] For example, the uplink positioning reference signal reported by the UE supports carrier aggregation, but the data transmission of the UE does not support carrier aggregation.

[0373] The UE may obtain configuration information for the uplink positioning reference signal from the LMF or a base station (or other communication entity).

[0374] For example, the configuration information of the uplink positioning reference signal includes one or more of: a. transmission information of the uplink positioning reference signal; and b. configuration information related to frequency hopping (FH).

[0375] a. Transmission information of uplink positioning reference signal For example, the transmission information of the uplink positioning reference signal includes a configuration of resources occupied for transmitting the uplink positioning reference signal and / or a configuration of a transmission scheme.

[0376] As mentioned above, the resource may be one or more of the following: bandwidth, BWP, RB, and subcarrier. The bandwidth configuration may include one or more of the following: bandwidth size, bandwidth position, center frequency indication, grid (raster) size, absolute frequency channel number, etc. The BWP configuration may include one or both of the following: BWP size and BWP position. The RB configuration may include one or more of the following: number of occupied RBs, occupied RB position, and starting RB position. The subcarrier configuration may include the supported subcarrier spacing. A "grid" is a type of bandwidth configuration parameter. The grid data is used to divide the space into regular grids. Each grid is called a unit. In the bandwidth configuration, the "grid size" refers to the granularity of dividing the entire frequency band.

[0377] For example, the transmission manner includes: whether the uplink positioning reference signal is transmitted based on the resource capability of the UE for the uplink positioning reference signal, or whether the uplink positioning reference signal is transmitted based on the resource capability of the UE for data transmission.

[0378] For example, the transmission manner includes whether the sequence of the uplink positioning reference signal is generated based on type 1 or whether the sequence of the uplink positioning reference signal is generated based on type 2.

[0379] For example, the transmission information of the uplink positioning reference signal may include scrambling code information used by the UE to generate the uplink positioning reference signal, The scrambling code information may be one or more of a scrambling code range and a scrambling code value set.

[0380] For example, the transmission information of the uplink positioning reference signal may include one or more of position information, period information, interval information, frequency hopping information, density information, guard time information, tuning time information, non-simultaneous transmission information, and non-simultaneous reception information of the uplink positioning reference signal.

[0381] The location information may be a location where an uplink positioning reference signal is transmitted. For example, the location where an uplink positioning reference signal is transmitted is within a specific time of an SSB. Since the location where a UE transmits an uplink positioning reference signal is specified to be within a specific time of an SSB, the UE can quickly perform synchronization tracking, which reduces power consumption.

[0382] The period information may be a period for transmitting the uplink positioning reference signal.

[0383] The interval information may be the (minimum) interval between two consecutive transmissions of the uplink positioning reference signal.

[0384] The density information may be the number of times that the uplink positioning reference signal is transmitted within a particular time range.

[0385] The reserved guard time information may be a length of time that needs to be reserved before an uplink positioning reference signal is transmitted, or a length of time that needs to be reserved after an uplink positioning reference signal is transmitted, or a length of time that needs to be reserved between two transmissions of an uplink positioning reference signal.

[0386] The tuning time information may be a switching time from an uplink positioning reference signal transmission to a next uplink positioning reference signal transmission.

[0387] The non-simultaneous transmission information may indicate that the UE does not transmit other uplink signal information (of one or more types) when transmitting the uplink positioning reference signal.

[0388] The non-simultaneous reception information may indicate that the UE does not receive other (one or more types of) downlink signal information when transmitting the uplink positioning reference signal.

[0389] b. Configuration information related to frequency hopping (FH) For example, configuration information related to frequency hopping may be Enable / Disable Frequency Hopping Includes one or both of the following:

[0390] Frequency hopping time domain configuration (one or more of starting position, interval, duration, number of symbols occupied by each hop, and frame / slot configuration).

[0391] Frequency hopping frequency domain configuration (one or more of starting RB position, number of RBs occupied by each hop (or one or more of frequency widths occupied by the signal at each hop), second resource width of each hop (e.g., used for phase estimation), number of hops on frequency at a particular time, frequency resource range of frequency hopping, subcarrier spacing information, and frequency hopping offset). At least one of the values ​​of the frequency hopping offset may allow frequency resources of two adjacent uplink positioning reference signals to overlap.

[0392] During frequency hopping transmission, for example, in FR1, the maximum number of RBs included in each hop is an integer multiple of 100 (or 50, or 106), or 1 / 2 or 1 / 4. For example, the value of the starting RB of the first hop is {0, ..., X-1}, where X is determined based on one or more of the number of hops on frequency, the remaining RBs, the carrier bandwidth, the BWP size, and the subcarrier spacing SCS. In particular, X=19, or X=49. The number of hops on frequency is the number of times the UE performs frequency hopping transmission on a specified frequency, and the remaining RBs refer to the number of RBs remaining after the UE transmits all SRSs in a frequency hopping manner on a specified frequency.

[0393] Alternatively, the UE may obtain indication information of the transmission scheme of the uplink positioning reference signal from the LMF or the base station (or other communication entity).

[0394] For example, the following defines a first mode and a second mode:

[0395] In the first mode, the uplink positioning reference signal is transmitted based on the uplink positioning reference signal resource capability of the UE.

[0396] In the second mode, the uplink positioning reference signal is transmitted based on the resource capability of the UE for data transmission.

[0397] For example, the LMF or base station (or other communication entity) indicates the transmission scheme for the UE with the following set: {first mode, no frequency hopping}, {second mode, frequency hopping}, and {second mode, no frequency hopping}.

[0398] For example, the LMF or base station (or other communication entity) indicates the transmission scheme for the UE with the following set: {first mode, no frequency hopping}, {second mode, frequency hopping}, {second mode, no frequency hopping}, and {first mode, frequency hopping}.

[0399] For example, the transmission scheme is predefined.

[0400] For example, if the resources occupied by the transmission of the uplink positioning reference signal are equal to or greater than the resource capability of the UE, the uplink positioning reference signal may be transmitted without frequency hopping (or without a frequency hopping indication) or may be transmitted via frequency hopping (or may be transmitted based on a frequency hopping indication).

[0401] For example, if the resources occupied by the transmission of the uplink positioning reference signal are equal to or less than the resource capability of the UE, the uplink positioning reference signal is transmitted by frequency hopping (or transmitted based on a frequency hopping indication).

[0402] For example, if the resource occupied by the transmission of the uplink positioning reference signal is equal to or larger than the resource capability of the uplink positioning reference signal of the UE, the uplink positioning reference signal is transmitted based on carrier aggregation. For example, if the resource capability of the uplink positioning reference signal of the UE is 100 MHz, the UE may transmit the uplink positioning reference signal in a carrier aggregation manner, and the occupied spectrum resource may be 100 MHz, 200 MHz, 300 MHz, etc.

[0403] For example, when the resources occupied by the transmission of the uplink positioning reference signal are equal to or less than the resource capability of the uplink positioning reference signal of the UE, the uplink positioning reference signal is transmitted based on a single carrier.

[0404] The resources occupied by the transmission of the uplink positioning reference signal may be greater than the resource capability of the UE. Depending on the configuration of the base station, the resources occupied by the transmission of the uplink positioning reference signal may be equal to or less than the resource capability of the UE. In particular, even if the resources occupied by the transmission of the uplink positioning reference signal are greater than the resource capability of the UE, the network may further configure the UE to transmit the uplink positioning reference signal in a frequency hopping manner to achieve better positioning performance. In particular, even if the resources occupied by the transmission of the uplink positioning reference signal are greater than the resource capability of the UE, the UE may further transmit the uplink positioning reference signal in a frequency hopping manner to achieve better positioning performance.

[0405] The configuration information of the uplink positioning reference signal includes transmission bandwidth information.

[0406] The UE transmits the SRS based on the configuration information received from the LMF or base station, which is the positioning reference signal.

[0407] Unless otherwise specified, in this embodiment of the present application, an example in which the resource is bandwidth is used to describe the implementation of this embodiment of the present application. However, it should be noted that if the resource has another definition, the definition is the same as the protected content of this embodiment of the present application.

[0408] Unless otherwise specified, in this embodiment of the present application, an uplink positioning reference signal is used as an example to describe the implementation of this embodiment of the present application. However, it should be noted that the uplink positioning reference signal in this embodiment of the present application may be replaced with other specific signals or channels (e.g., other uplink signals or channels, or other downlink signals or channels). This also belongs to the protection content of this embodiment of the present application. PRS: Downlink positioning.

[0409] In this embodiment of the application, a transmission can be a transmission and / or a reception: when a transmission on one side of a communication is transmitting, a transmission on the peer device of the communication is receiving.

[0410] In embodiment 1, the UE determines the maximum bandwidth for the UE to transmit the positioning reference signal, and the UE determines the maximum bandwidth for data transmission, which can effectively avoid a large increase in the complexity / cost of the UE and help reduce the power consumption of the UE while ensuring high-precision positioning.

[0411] At present, the maximum bandwidth of the positioning signal is closely coupled with the data transmission bandwidth of the UE. In embodiment 1, the UE determines the maximum bandwidth of the positioning signal, and the UE determines the data transmission bandwidth of the UE. In other words, the maximum bandwidth for transmitting the positioning reference signal by the UE is no longer limited to the data transmission bandwidth of the UE.

[0412] EMBODIMENT 2 Embodiment 2 is for a network unit. For example, the network unit may be an LMF, a base station, or other communication entity. As shown in Figure 3a, the method mainly includes the following steps:

[0413] Step S03: The network unit may obtain (maximum) resource capability information of the UE's uplink positioning reference signal from the UE.

[0414] For example, the resource capability information of the uplink positioning reference signal includes one or more of the following: a maximum bandwidth that can be occupied when the UE transmits the positioning reference signal on a single carrier, whether the UE supports carrier aggregation CA of the uplink positioning reference signal, the number of carriers on which CA can be supported by the UE, a maximum bandwidth after the UE supports positioning reference signal CA, a tuning time of the UE, etc.

[0415] For example, the resource capability information of the uplink positioning reference signal may indicate that the UE supports generation of sequences based on Type 1, or that the UE supports generation of sequences based on Type 2. Alternatively, the resource capability information of the uplink positioning reference signal may further indicate that the UE supports generation of sequences based on Type 1, or that the UE supports generation of sequences based on Type 2, or that the UE supports generation of sequences based on Types 1 and 2.

[0416] For example, the resource capability information of the uplink positioning reference signal may include scrambling code information used by the UE to generate the uplink positioning reference signal, The scrambling code information may be one or more of a scrambling code range and a scrambling code value set.

[0417] For example, the resource capability information of the uplink positioning reference signal may include one or more of location information, period information, interval information, frequency hopping information, density information, reserved time information, tuning time information, non-simultaneous transmission information, and non-simultaneous reception information of the uplink positioning reference signal of the UE.

[0418] The location information is for transmitting an uplink positioning reference signal and may be a location that can be supported by the UE, for example, a fixed location or a flexible location. Alternatively, the location where the UE transmits the uplink positioning reference signal is within a specific time of the SSB. Since the location where the UE transmits the uplink positioning reference signal is within a specific time of the SSB, the UE can quickly perform synchronization tracking, which reduces power consumption. The location information obtained from the UE may be an expected specific time value or range.

[0419] The period information may be a period for transmitting an uplink positioning reference signal that may be supported by the UE.

[0420] The interval information may be the (minimum) interval that may be supported by the UE between two consecutive transmissions of the uplink positioning reference signal.

[0421] The frequency hopping information may be one or more of: whether the uplink positioning reference signal of the UE supports frequency hopping, the number of hops at a particular time, the number of RBs occupied by each hop (or the frequency width occupied by the signal at each hop), the second resource width at each hop, a frequency hopping offset, a frequency resource range of the frequency hopping, and subcarrier spacing information. At least one of the values ​​of the frequency hopping offset may allow the frequency resources of two adjacent uplink positioning reference signals to overlap.

[0422] The density information may be the number of times that the UE transmits an uplink positioning reference signal within a particular time range.

[0423] The reserved time information may be a time length that needs to be reserved before the UE transmits an uplink positioning reference signal, or a time length that needs to be reserved after the UE transmits an uplink positioning reference signal, or a time length that needs to be reserved between two transmissions of an uplink positioning reference signal by the UE.

[0424] The tuning time information may be a switch time from an uplink positioning reference signal transmission to a next uplink positioning reference signal transmission by the UE.

[0425] The non-simultaneous transmission information may indicate that the UE does not support transmission of other uplink signals (of one or more types) when transmitting the uplink positioning reference signal.

[0426] The non-simultaneous reception information may indicate that the UE does not support reception of other downlink signals (of one or more types) when transmitting an uplink positioning reference signal.

[0427] Alternatively, the network unit may pre-specify some resource capability information of the uplink positioning reference signal of the UE. For example, reserved time information is pre-specified, or non-simultaneous transmission information is pre-specified, or non-simultaneous reception information is pre-specified. For example, the time that the UE needs to reserve before or after transmitting the uplink positioning reference signal is pre-specified. For example, it is pre-specified that the UE cannot transmit PUSCH and / or PUCCH when transmitting the uplink positioning reference signal. For example, it is pre-specified that the UE cannot receive PDSCH and / or PDCCH when transmitting the uplink positioning reference signal. For example, it is pre-specified that the position where the UE transmits the uplink positioning reference signal is within n ms after the SSB. For example, n=5 or n=10.

[0428] Specifically, the resource capability of the UE may be pre-specified, or the network unit may further obtain the resource capability information of the UE from the UE. For example, the resource capability information of the UE is a (maximum) resource capability of data transmission. For example, the maximum bandwidth for the data transmission of the UE is pre-specified, or the data transmission of the UE is pre-specified not to support CA. For example,

[0429] Step S04: The network unit may obtain from the UE (maximum) resource capability information of the UE's data transmission.

[0430] For example, the resource capability information for data transmission includes one or more of the following: a maximum bandwidth for data transmission of the UE, a maximum baseband bandwidth for data transmission of the UE, a maximum radio frequency bandwidth for data transmission of the UE, carrier aggregation CA that the UE does not support for data transmission, a number of carriers for which CA can be supported by the UE data transmission, a maximum bandwidth after the UE data transmission supports CA of a positioning reference signal, a tuning time for data transmission of the UE, and the like.

[0431] It should be noted that the (maximum) resource capability of the UE's uplink positioning reference signal may be greater (or higher) than the (maximum) resource capability of the data transmission. Of course, the (maximum) resource capability of the UE's uplink positioning reference signal may alternatively be less than or equal to the (maximum) resource capability of the data transmission.

[0432] The following provides some illustrative examples.

[0433] For example, the resource capability information of the uplink positioning reference signal obtained from the UE is as follows: {Bandwidth(RB):ENUMERATED{n50,n100,n200,n300,n400,…}. SCS:{15KHz,30KHz,...} CA info}

[0434] For example, the resource capability information of the uplink positioning reference signal obtained from the UE is as follows: {Bandwidth(MHz):ENUMERATED{n10,n20,n40,n60,n100,n200,…} SCS:{15KHz,30KHz,...}}

[0435] For example, the bandwidth of the uplink positioning reference signal obtained from the UE is 100 MHz, and the bandwidth of the UE is 20 MHz.

[0436] For example, the bandwidth of the uplink positioning reference signal obtained from the UE is N RBs, and the bandwidth of the UE is M RBs, where N>M.

[0437] For example, an uplink positioning reference signal obtained from a UE supports carrier aggregation, but the data transmission of the UE does not support carrier aggregation.

[0438] The network unit may send, to the UE, configuration information of the UE's uplink positioning reference signal.

[0439] For example, the configuration information of the uplink positioning reference signal includes one or more of: a. transmission information of the uplink positioning reference signal; and b. configuration information related to frequency hopping.

[0440] a. Transmission information of uplink positioning reference signal For example, the transmission information of the uplink positioning reference signal includes a configuration of resources occupied for transmitting the uplink positioning reference signal and / or a configuration of a transmission scheme.

[0441] As mentioned above, the resource may be one or more of a bandwidth, a BWP, an RB, and a subcarrier. The bandwidth configuration may include one or more of a bandwidth size, a bandwidth location, a center frequency indication, a grid (raster) size, an absolute frequency channel number, etc. The BWP configuration may include one or both of a BWP size and a BWP location. The RB configuration may include one or more of a number of occupied RBs, an occupied RB location, and a starting RB location. The subcarrier configuration may include a supported subcarrier spacing.

[0442] For example, the transmission manner includes: whether the uplink positioning reference signal is transmitted based on the resource capability of the UE for the uplink positioning reference signal, or whether the uplink positioning reference signal is transmitted based on the resource capability of the UE for data transmission.

[0443] For example, the transmission manner includes whether the sequence of the uplink positioning reference signal is generated based on type 1 or whether the sequence of the uplink positioning reference signal is generated based on type 2.

[0444] For example, the transmission information of the uplink positioning reference signal may include scrambling code information used by the UE to generate the uplink positioning reference signal, The scrambling code information may be one or more of a scrambling code range and a scrambling code value set.

[0445] For example, the transmission information of the uplink positioning reference signal may include one or more of position information, period information, interval information, frequency hopping information, density information, guard time information, and tuning time information of the uplink positioning reference signal.

[0446] The location information may be a location where an uplink positioning reference signal is transmitted. For example, the location where an uplink positioning reference signal is transmitted is within a specific time of an SSB. Since the location where a UE transmits an uplink positioning reference signal is specified to be within a specific time of an SSB, the UE can quickly perform synchronization tracking, which reduces power consumption.

[0447] The period information may be a period for transmitting the uplink positioning reference signal.

[0448] The interval information may be the (minimum) interval between two consecutive transmissions of the uplink positioning reference signal.

[0449] The density information may be the number of times that the uplink positioning reference signal is transmitted within a particular time range.

[0450] The reserved guard time information may be a length of time that needs to be reserved before an uplink positioning reference signal is transmitted, or a length of time that needs to be reserved after an uplink positioning reference signal is transmitted, or a length of time that needs to be reserved between two transmissions of an uplink positioning reference signal.

[0451] The tuning time information may be a switching time from an uplink positioning reference signal transmission to a next uplink positioning reference signal transmission.

[0452] The non-simultaneous transmission information may indicate that the UE does not transmit other uplink signal information (of one or more types) when transmitting the uplink positioning reference signal.

[0453] The non-simultaneous reception information may indicate that the UE does not receive other (one or more types of) downlink signal information when transmitting the uplink positioning reference signal.

[0454] b. Configuration information related to frequency hopping For example, configuration information related to frequency hopping may be Enable / Disable Frequency Hopping Includes one or both of the following:

[0455] Frequency hopping time domain configuration (one or more of starting position, interval, duration, number of symbols occupied by each hop, and frame / slot configuration).

[0456] Frequency hopping frequency domain configuration (one or more of starting RB position, number of RBs occupied by each hop (or one or more of frequency widths occupied by the signal at each hop), second resource width of each hop (e.g., used for phase estimation), number of hops on frequency at a particular time, frequency resource range of frequency hopping, subcarrier spacing information, and frequency hopping offset). At least one of the values ​​of the frequency hopping offset may allow frequency resources of two adjacent uplink positioning reference signals to overlap.

[0457] During frequency hopping transmission, e.g., in FR1, the maximum number of RBs included in each hop is an integer multiple of 100 (or 50, or 106), or ½ or ¼. For example, the value of the starting RB of the first hop is {0,…,X-1}, where X is determined based on one or more of the number of hops on frequency, the remaining RBs, the carrier bandwidth, the BWP size, and the SCS. In particular, X=19, or X=49.

[0458] Alternatively, the network unit may send, to the UE, an indication of the transmission manner of the UE's uplink positioning reference signal.

[0459] For example, the following defines a first mode and a second mode:

[0460] In the first mode, the uplink positioning reference signal is transmitted based on the uplink positioning reference signal resource capability of the UE.

[0461] In the second mode, the uplink positioning reference signal is transmitted based on the resource capability of the UE for data transmission.

[0462] For example, the network unit indicates the transmission scheme for the UE with the following set: {first mode, no frequency hopping}, {second mode, frequency hopping}, and {second mode, no frequency hopping}.

[0463] For example, the network unit indicates the transmission scheme for the UE with the following set: {first mode, no frequency hopping}, {second mode, frequency hopping}, {second mode, no frequency hopping}, and {first mode, frequency hopping}.

[0464] For example, the transmission scheme is predefined.

[0465] For example, if the resources occupied by the transmission of the uplink positioning reference signal are equal to or greater than the resource capability of the UE, the uplink positioning reference signal may be transmitted without frequency hopping (or without a frequency hopping indication) or may be transmitted via frequency hopping (or may be transmitted based on a frequency hopping indication).

[0466] For example, if the resources occupied by the transmission of the uplink positioning reference signal are equal to or less than the resource capability of the UE, the uplink positioning reference signal is transmitted by frequency hopping (or transmitted based on a frequency hopping indication).

[0467] For example, if the resource occupied by the transmission of the uplink positioning reference signal is equal to or larger than the resource capability of the uplink positioning reference signal of the UE, the uplink positioning reference signal is transmitted based on carrier aggregation. For example, if the resource capability of the uplink positioning reference signal of the UE is 100 MHz, the UE may transmit the uplink positioning reference signal in a carrier aggregation manner, and the occupied spectrum resource may be 100 MHz, 200 MHz, 300 MHz, etc.

[0468] For example, when the resources occupied by the transmission of the uplink positioning reference signal are equal to or less than the resource capability of the uplink positioning reference signal of the UE, the uplink positioning reference signal is transmitted based on a single carrier.

[0469] The resources occupied by the transmission of the uplink positioning reference signal may be greater than the resource capability of the UE. Depending on the configuration of the base station, the resources occupied by the transmission of the uplink positioning reference signal may be equal to or less than the resource capability of the UE. In particular, even if the resources occupied by the transmission of the uplink positioning reference signal are greater than the resource capability of the UE, the network may further configure the UE to transmit the uplink positioning reference signal in a frequency hopping manner to achieve better positioning performance. In particular, even if the resources occupied by the transmission of the uplink positioning reference signal are greater than the resource capability of the UE, the UE may further transmit the uplink positioning reference signal in a frequency hopping manner to achieve better positioning performance.

[0470] The network unit may receive the SRS transmitted by the UE based on the reference signal configuration information.

[0471] In embodiment 2, a network unit (e.g., LMF / base station / other communication entity) can send configuration information of the UE's positioning reference signal to the UE, and indicate or configure the transmission bandwidth, transmission manner, whether frequency hopping is performed, whether CA is supported, etc., so that different positioning traffic requirements can be met, which effectively avoids a significant increase in the complexity / cost / power consumption of the UE.

[0472] In embodiment 2, a network unit (e.g., LMF / base station / other communication entity) sends configuration information of positioning reference signal to UE, including an indication of transmission bandwidth and transmission scheme, a report of SRS bandwidth and frequency hopping integration capability, a detailed starting resource indication, etc. Currently, such fine-grained and flexible configuration is not performed for SRS configuration information.
